Description

The invention relates to a winding device for winding webs of material, in particular fibrous webs to a winding roll with a winding roll to be wound during the winding process and at least partially wrapped by the web carrier roll.

Winding devices in the form of support roll winder devices are previously known in a variety of prior art designs. These comprise at least two rotatably mounted support rollers, which are arranged axially parallel to each other and rotatably supported. The support rollers together form a winding bed for receiving and supporting a winding roll. The winding roll is formed by winding the web about a sleeve, wherein the web is guided around one of the two support rollers over a portion of the circumference. This is a drivable carrier roll. However, the web to be wound up often has a greater length than can be wound up on the corresponding winding roll. This is the case, in particular, when the material web is unwound from a larger master roll or is wound up continuously in the on-line construction of the winding apparatus into a machine for producing the material web during the production process. This implies that the finished winding roll must be removed from the winding device and a new coiled sleeve must be inserted into the winding bed. For this purpose, the material web is to be cut, wherein the end of the material web lying behind the separation point viewed in the material web running direction is glued to the finished wound reel while the end lying in front of the separation region the web must be attached to the newly inserted sleeve. For this purpose, for example, transfer rollers can be used, which serve to stick adhesive strips on the material web.

The severing of the material web is carried out according to a first embodiment, either at standstill of the machine manually by the operator or via appropriate separation devices that are effective on the material web in the free train usually. From the publication DE 198 04 411 A1 For this purpose, for example, a method for passing a material web from a winding roll to a winding tube and a winding device in the form of a Doppeltragwalzenrollers previously known. This comprises a separating device and an adhesive applicator. In this embodiment, the web is lifted and cut in the separation area before severing from the support roller. The separation is effected by the action of the separating element on the material web in free tension, wherein the corresponding tensile stress on the material web is generated by the forces in the winding nips, in particular the winding nip through which the material web passes to the winding roll. The clamping means are released after inserting a new winding tube of the resulting by the separation process web edge and the clamping device is moved back in the web running direction. The separation process takes place here by lowering and displacement of the winding roll on one of the support rollers with the winding nip and forming a portion of the free train between the support roller and the winding roll, wherein in the region of the free train, the separating element in the form of cutting knives is effective.

From the publication DE 198 08 041 A1 is a method for passing a material web from a winding roll to a winding tube previously known, in which the web is completely severed by a distance before a transfer area and the cutting line is pasted over with an adhesive tape. For this purpose, the winding device at a distance in front of the transfer area on a cutting device, which is arranged downstream of an applicator, which covers the previously generated cutting line with an adhesive tape.

Another winding device with integrated cutting device for severing the material web in a winding or sleeve change is from the document WO 97/47546 A1 previously known. The embodiment relates to a Doppeltragwalzenwickelvorrichtung, wherein the separating device can be arranged in the region of the winding bed.

Each of these mentioned embodiments is characterized in that the separation process of the material web takes place in front of the winding tube in the free train of the material web, whereby it is brought to tension. Common to the embodiments is that the device for the realization of the separation process has to be stopped, which is very detrimental to the productivity. The realization of a free train of material web in the separation area is very expensive in terms of additional control devices and the required control engineering effort. For the purpose of applying an adhesive in the region of the cut edges fixed adhesive nozzles or adhesive tape dispensers are usually provided in the device, which are arranged distributed over the working width of these. The required effort for installation and control is relatively high.

A generic winding device is from the document WO 92/06911 A1 previously known. This discloses an embodiment for severing an endlessly moving material web which is wound onto a winding roll in a double-take-up winder. For this purpose, a separating device is employed in the region of the intermediate space between the two support rollers to which the material web to the winding roller leading support roller. This comprises a slidable over the width of the support roller laser cutting device, which is arranged between two adhesive-applying nozzles and allows separation of the web in the supported by the support roller wrap. The disadvantage of this design is a high technical control effort and the necessary for safety reasons and to avoid damage to the winding device overhead for shielding. Because the surface of the Carrier roller must not be damaged in terms of their nature by the separation process, to effect for this with the winding operations no impairment of the wound web, the laser must be controlled from the surface of the support roller reflected and shielded from the environment.

The invention therefore an object of the invention to develop a winding device such that the disadvantages mentioned are avoided and a separation of the web during the winding process with low design and control effort is feasible without having to stop the entire machine and also the number of means is reduced for the application of adhesive.

The solution according to the invention is characterized by the features of claims 1 and 3. Advantageous embodiments are described in the subclaims.

The winding device for winding webs of material, in particular fibrous webs to a winding roll with, the winding roll to be wound during the winding process and supported by the web at least partially wrapped support roll, with at least one on the outer circumference of the support roller in the wrap through the web to this engageable and on the Material web effective separating device for separating the material web at an angle to the running direction of the material web, according to a first embodiment, characterized in that the separating device is designed as a mechanical separating device, comprising at least one separating element in the form of a cutting device. According to a second embodiment, the separating device is designed as a water cutting separator.

The solution according to the invention makes it possible on the one hand to sever the material web during ongoing operation, that is to say stopping the device is not necessary. The productivity and utilization of the device This can be considerably increased. Furthermore, the solution according to the invention is characterized by a simple and space-saving design. On a complex shielding, as in the prior art can be omitted. The cutting depth can be reproduced by the simple adjustability of the cutting element or the water jet and the action on the surface supporting the material web can be avoided by the formation and adjustment of the cutting element, in particular surface damage to the support roller.

According to the first embodiment, the separating device used comprises at least one separating element which can be moved over the width of the material web with respect to its movement transversely across the material web. In a separating device according to the second embodiment, in addition to a design with only one or a group of movable nozzles also conceivable that the width of the material web is completely covered by a series of juxtaposed and individually or jointly controllable nozzles, which at a distance to Carrier roller are arranged and can be activated and deactivated only by controlling the supply of the corresponding cutting medium. In this case, the design and control engineering effort is low.

In versions with axially displaceable separating element, the displaceability can be realized in different ways. In particular, according to a first embodiment, the separating element can either be moved parallel to the bearing axis of the carrier roll in the widthwise direction or can be moved over the extension in the width direction of the carrier roll and in the circumferential direction in a superimposed movement parallel to the surface of the carrier roll. Further conceivable is a mobility within a linear guide, which is arranged inclined in the direction of movement relative to a horizontal plane.

The former case has the advantage that, regardless of the nature of the design of the separating element no special requirements with respect to the alignment with respect to the surface of the support roller or the material web roll supported by this are required. The resulting cutting edge on the material web is always inclined. The angle of inclination relative to the material web running direction can be described as a function of the feed rate of the separating element and the feed rate of the material web in the web web travel direction.

According to the second alternative, the individual separating element is moved in such a way to the surface of the support roller and the material web supported thereon that the movement is composed of a movement transversely to the material web travel direction and in the material web travel direction. Depending on the design, the cutting edge can be influenced by appropriate control of the velocity components in the respective direction. When guiding parallel to the surface can be dispensed with balancing devices and adjusting devices.

The third variant is analogous to the second of generating a straight or slightly inclined cutting edge. However, this is characterized by a simple design of the guideway, with standardized linear guides can be used.

With regard to the configuration of the individual separating element, there are a plurality of possibilities. According to a first embodiment, this is designed as a mechanical cutting device, preferably in the form of a so-called pinch knife. In this case, the separation process takes place by direct contact of the separating element with the surface of the material web in the support region on the support roller. Depending on the type and design of the carrier roll used, the separation can be generated directly by a cut or a tearing process.

According to the second embodiment, water jets are used as a separation medium. The cutting force can be adjusted in a simple manner by controlling the parameters at the outlet nozzles. This embodiment has the advantage that it is independent of the position of the guide device relative to the support roller by the possibility of alignment of the nozzle. In particular, with an inclined design of the guide for the separating element, a distance adjustment between the guide and the surface is not required.

When using individual separating elements, these are across the width of the support roller, and thus the supported material supported by this web. The separating element can be designed to be movable parallel to the bearing axis of the support roller or in the circumferential direction parallel to the surface / outer circumference of the support roller. According to a further embodiment, the separating element is guided in an extending in the width direction of the support roller and inclined relative to the running direction guide track, the inclination preferably in the range between 0.5 to 10 °, more preferably 0.5 to 5 °, most preferably 0.5 to 2 °. In this case, with a simplified design of the guide, the separating element is preferably assigned means for compensating for a change in distance between the guide track and the surface or outer circumference of the carrier roller in the direction of movement along the guide track.

If mechanical cutting devices are used, means for setting the separating element in a predefined angle, preferably 90 ° with respect to a tangent to the surface of the support roller on the outer circumference are advantageously provided to avoid tilting and realization of a simple cut. This is done in a simple manner via the articulated connection to an axis parallel to the bearing axis of the support roller or on both sides of the cutting element associated guide rollers.

Structurally, the single separating element in the simplest case can be guided on a bearing and guide device. The bearing and guide device is opposite the roller is adjustable The guide is made by means of rolling or slide mounted carriages.

In order to ensure a smooth change of a coil, the separation device is viewed in the web direction of travel provided at least one means for application of application agent, in particular adhesive on the web in the region of the cutting edges produced at the cutting process on the web. As a result, the material web can be glued in the area of the cutting edge on the winding side with the winding, while the material web is material web roll side with the adhesive edge of the new sleeve can be fed and secured thereto. For this purpose, the devices can be guided on the bearing and guide device of the separating element or on a separate bearing and guide device parallel to the bearing and / or guide device of the separating element. In order to carry out the adhesive edge in a timely manner with the separation process and, if possible, parallel to the cutting edge, the devices and the separating element are preferably positively coupled in their movement across the width of the winding device.

The FIGS. 1a and 1b illustrate in a schematic simplified representation of the basic structure of a winding device 1 according to the invention for winding material webs M, in particular in the form of paper, cardboard or tissue webs in two views. The winding device 1 comprises at least one during the winding process of the wound web of material M at least partially wrapped in the circumferential direction of the support roller 2. The winding device 1 is formed in the illustrated case by way of example in a particularly advantageous embodiment as a double carrier rollers winding device. This comprises in addition to the support roller 2, a further support roller 3. Both support rollers 2 and 3 are axially parallel to each other, rotatably mounted and together form a winding bed 4 for receiving a coil 5. The winding bed 4 is of the theoretically possible contact area of the coil 5 at the outer peripheries 6 and 7 of the support rollers 2 and 3 are formed. The winding 5 is formed by Winding the material web M to a sleeve 8, wherein the material web M is guided around the support roller 2. The sleeve 8 or later by rolling up the material web M from this resulting winding 5 forms with the two support rollers 2 and 3 by the linear or surface contact on the outer peripheries 6 and 7, the winding nips 9 and 10. Depending on the configuration of the support rollers. 2 and 3, in particular with regard to the sizes of their diameters and the arrangement of their bearing axes L ₂ and L ₃ to each other in the vertical and horizontal directions, the winding bed 4 in a horizontal plane or inclined thereto. The bearing axes L ₂ and L ₃ coincide with the axes of rotation of the support rollers 2 and 3. If a predefined winding size D _{soll of} the roll 5, which can be described by the diameter of the roll 5, is reached, this is removed from the winding device 1. For this purpose, it is necessary to separate the winding 5 from the material web M, which is guided around the support roller 2. According to the invention, a separating device 11 is provided for this purpose, which separates the winding 5 from the part of the material web M to be fed outside of the roll 5, wherein the separation takes place in a region supporting the material web M, the wrapping region 16 on the support roll 2, ie the separation takes place not in the free train of the material web M. The separation device 11 according to the invention the transfer roller 2 can be assigned, which is also driven, and serves to realize a separation of the material web M transversely to the direction of the web M or at an angle to the direction of the material web M before Depending on the design of the separating device 11 and arrangement, the material web M is perpendicular to the material web running direction before entering the central gap 9 separated on the first support roller 2 or cut edges 18, 19 inclined to this generated. In the simplest case, the separating device 11 comprises, for this purpose, a bearing and / or guide device 12, on which at least one separating element 13 can be guided parallel to the support roller 2 over the width of the material web M in the region which encloses the support roller. This offers the advantage that the separating element can be used for a large number of different embodiments of winding devices 1, wherein the respective assignment takes place via the design of the bearing and / or guide device 12, which corresponds to the respectively required width of Carrier roller 2 is customizable. The width of the support roller is here designated b ₂ and corresponds to the installation in the winding device 1 of the width direction CD of the machine. In FIG. 1a For this purpose, a coordinate system is indicated, wherein the x-direction corresponds to the guide direction of the material web M, while the y-direction corresponds to the width direction of the winding device 1. The z-direction describes the height direction. The FIG. 1a illustrates a view in the xz-plane of the winding device 1, which corresponds to a view from the right, while the FIG. 1b a view from the front clarifies. Visible here is in particular the location of the separating device 11. Die Figure 1c exemplifies the employment of the separating element 13 in the form of a cutting element 14, in particular in the form of a knife 20 to the outer periphery 6 of the support roller. 2

The FIG. 1a illustrates an embodiment with a movable, that is adjustable separating element 13, wherein the separating element 13 is adjustable with respect to its position in the width direction for the realization of the separation process. According to Figure 1c is the separating element 13 in a particularly advantageous embodiment in a simple manner as a cutting element 14, in particular knife 20 is formed. The cutting edge 15 of the cutting element can be adjusted against the outer circumference 6 of the carrier web 2 looped around by the material web M in the wrapping region 16 before entering the winding nip 9. The angle of attack is according to the detail view X off FIG. 1a denoted by β. The separating element 13, in particular the cutting element 14 is adjustable in the bearing and guide device 12 along this parallel to the outer periphery 6 of the support roller 2. In this regard, there are different possibilities. In the FIGS. 1a and 1b an arrangement with parallel to the bearing axis L ₂ arranged separating device 11 is shown. The bearing and guide device 12 extends axially parallel to the bearing axis 2, whereby the writable by this guide track is parallel to the axis. The distance between the guide 17 formed in this surface to the support roller 2 is constant over the extension of the support roller 2 in the width direction. The separating element 13 is displaceable only in the guide 17, wherein its position in Width direction changes. The adjustment to the outer circumference is the same across the width, so that the position is maintained in the x-direction during the adjustment process in the guide 17. In this embodiment, depending on the winding speed and thus the peripheral speed of the material web M on the outer circumference 6 of the material web M an inclined to material web running direction running cut edge 18, 19 generated at the web end regions in the separation area, as in Figure 1d shown. In this case, the winding 5 associated cutting edge 19 advantageously forms the end of the roll 5 and the cutting edge 18 in complementary manner to the separated web part M the beginning of a newly wound up winding 5. The cut edge course is exemplary in the Figure 1d reproduced, wherein the inclination relative to the material web running direction can be influenced by the superposition of material web running speed and feed speed of the separating element. Figure 1d illustrates only in a view of the material web M the course of the cutting edges. The end part of the roll 5 is shown in the unwound position. The resulting by the cutting edge course of the material web M at the end of the roll 5 is denoted by 19, while the remaining material web portion to be wound, here designated M, and the cutting edge present after the cutting process is denoted by 18.

The knife 20 is designed in a particularly advantageous manner as a crushing knife. This allows in addition to easy handling a quick cutting width adjustment and blade change and is particularly suitable for cutting thin materials. The wedge-shaped knife edge presses directly on a counter surface, here the surface of the support roller 2 and squeezes the material apart.

In contrast, the clarify FIGS. 2a to 2d in an analogous version to the versions in the FIGS. 1a to 1d an arrangement with a separating element in the form of a cutting element 14, in particular a knife 20, in which according to Figure 2d a cut edge course 18, 19 at the Material web M is generated, which is aligned perpendicular to the material web travel direction. In this case, the separation process is achieved by a straight cut, as it were, parallel to the axis of the roll 5 L ₅ . In this case, the separating device 11 is set against the support roller 2, in particular in the z-direction at an angle γ, thereby depending on the speed of the web M along the outer circumference 6 on the support roller 2 and the feed rate of the cutting element 14 in the camp - And guide means 12 results in a straight course of the cutting edge 18 and 19 respectively. When using a mechanical cutting element, which touchingly acts on the material web M, the course of the lateral surface of the support roller 2 in the circumferential direction is also taken into account, so that via the separating device 11, in particular the bearing and guide device 12 and / or the connection of the separating element 13th at this, always a concern of the separating element 13 is ensured on the outer circumference 6. This can be done by appropriate additional inclination of the bearing and guide device 12 in the x direction or via adjustment mechanisms in the connection between the separating element 13 and the bearing and guide device 12. In the first case would be resulting from the bearing and guide means guideway parallel to the surface of the support roller 2. In this case, no special measures regarding the management of the separating element 13 are required. In the second case, the guide can be arranged inclined as a linear guide in the vertical direction. The resulting due to this arrangement different distances of the guide track from the surface of the support roller 2 in the direction of the guide are compensated by appropriate means for compensating for a change in distance in the connection between the separating element 13 and guide 17 in the movement within the guide 17.

In the embodiments according to the FIGS. 1 and 2 the separating element 13 is designed as a contacting separating element, which separates in direct operative connection with the material web M and the mating surface supporting this on the outer circumference 6 of the carrier roll 2. In this embodiment, the separating element 13 is formed as a mechanical separating element, which along the outer periphery the support roller 2 in the width direction of this guide is mounted. According to a particularly advantageous embodiment, a straight guide is used in which the separating element 13 in the form of the cutting element 14 by means of a carriage 21 is movable. In order to guide the cutting element 14, in particular the cutting edge always perpendicular to the surface of the outer periphery 6 of the support roller 2, means 22 may be provided which allow a setting of the cutting element 14 in the desired manner on the outer circumference 6. These can, depending on the design and arrangement of the guide 17, comprise means 28 for compensating for the change in distance between the guide track and the surface of the carrier roller 2. The cutting element 14 is guided over a bearing element 23 in the guide 17. The bearing element 23 is formed by a carriage 21 in the simplest case. At this, the knife 20 is mounted virtually pivotally and slidably guided in the bearing and guide device 12 over the width direction of the support roller 2. The connection to the carriage 21 via a hinge 24. The hinge 24 is designed and arranged such that it allows mobility about an axis parallel to the surface of the support roller 2. The means 22 further comprise on both sides of the cutting element 14 arranged rolling or sliding elements, for example in the form of guide rollers 25 or runners.

According to an advantageous development of the embodiment according to the FIGS. 1 to 3 can at the bearing and guide means 12 and at least one means 26 for applying a pasty medium, which simultaneously serves the application of glue or an adhesive agent on the material web M in the region of the cut edges 18, 19 are provided, so that here at the same time Function of the beginning and Endverklebung can be realized, that is, in particular the application in web direction before or after the cutting edge. For this purpose, corresponding sub-devices are to be placed on the bearing and guide device 12 in a corresponding manner.

FIG. 4a illustrated by a detail view according to the FIGS. 1c and 3a the arrangement of the devices 26 on the storage and / or Guide device 12 of the separating element 13. The arrangement of the devices 26, preferably in the form of a nozzle, takes place on both sides of the theoretical guideway of the separating element 13 immediately adjacent to this viewed in the material web running direction in front of and / or behind the separating element 13 FIG. 4a the bearing and guide device 12 of the separating element 13 are used with. The guideway of the devices 26 is parallel to the guideway of the separating element 13. It is conceivable, however, as in FIG. 4b exemplified to provide 26 separate guides for the devices. However, these are also preferably parallel to the bearing and / or guide device 12 of the separating device 11. The arrangement of the devices 26 is displaceable, wherein the sliding movement with the movement of the separating element positively coupled or synchronously, whereby the cut is accompanied by simultaneous application of the application means. It is also conceivable to control the devices 26 such that their movement is slightly upstream or downstream of the movement of the separating element 13.

When forming the cutting elements 14 in the form of knives are doing according to the FIGS. 5a and 5b 2 different effects achieved depending on the design of the support roller. Is the support roller 2 according to the FIG. 5a formed as a steel roller, causes the action of the cutting element 14 by employment on the outer circumference 6 a section through the material web M, while according to FIG. 5b with the same design of the cutting element 14, but elastic formation of the surface of the support roller 2 by a reference 27 an elastic deformation of the material web M is effected, which is characterized by the impressions in the reference 27 and by squeezing a rupture of the material web M in the effective range of Cutting elements 14 causes. As a result, in analogy to FIG. 5a although cut edges, which are visually of those according to FIG. 5a hardly distinguishable, but with a corresponding resolution considered by the different effects are clearly differentiated.

The designs in the FIGS. 1 to 4 represent particularly advantageous embodiments. However, especially in the embodiment according to FIG. 2 To dispense with the additional Ausjustierung the cutting element 14, and separating devices 11 can be used, which are based on other principles. According to FIG. 6 the separating device 11 is designed as a water jet cutting device 30. This comprises in the simplest case one on a bearing and guide device 12, which is arranged parallel to the surface of the support roller 2, but at least parallel to the bearing axis L _{2 of} the support roller 2, over the width direction, that is preferably parallel to the bearing axis L ₂ slidably disposed nozzle 8, from which a jet of water emerges at great speed. It is also conceivable here to provide a series of nozzles extending over the width of the material web, which nozzles are arranged parallel to one another in the width direction next to one another and can be actuated at the same time.

The in the FIG. 6 illustrated embodiment has the advantage that here usually no readjustment with respect to the distance between the separator 11 and the surface of the support roller 2 must be made depending on the desired cutting or separating edge, but the separating elements 13 guided directly along the writable by the guide track can be, no matter whether a vertical course of the cutting edge is desired or an inclined with different distances are compensated by the intensity of the water jet used.

The FIGS. 7a to 7c illustrate in a simplified schematic representation of the possibilities of adjustability of the separating device 11 in order to spend this in the desired position in the desired separation process and in non-operation in a parking position. It can according to an embodiment in FIG. 7b the position of the bearing and guide device 12 of the separator 11 in all functional states, that is, operation of the separator 11 or non-operation, are maintained unchanged, that is, this is stationary. The separating device 11 is either activated / deactivated or the separating element 13 is in the non-active position from the extension of the support roller 2 in Moved out width direction, which is why the bearing and guide device 12 is longer than the width of the support roller 2 executed.

In contrast, the clarify FIGS. 7a and 7c Versions with complete separate adjustability of the bearing and guide device 12 via actuators. Depending on the winding width, it is also conceivable here, the bearing and guide device 12 according to Figure 7a to make completely pivotable, wherein the pivoting preferably takes place upwards or downwards, that is in the z-direction. Furthermore, according to FIG. 7c the bearing and guide device 12 be designed to be displaceable in the x direction.

With respect to the concrete structural design, there are a variety of possibilities, but in detail at the discretion of the skilled person.
