2. Description of the Related Art As a conventional example of this kind, JP-A-55-44
The invention described in Japanese Patent Publication No. 420 is known. This example relates to a transported object aligning apparatus including a plurality of traveling bodies for sending out a plurality of transported objects such as tiles which are supported and sent in advance at predetermined intervals only in two ways, a dense state and a diffused state. It is a device that can accurately and quickly change the interval between conveyed items.

Since the traveling bodies having fixed fingers for holding the conveyed objects such as tiles are connected by the pantograph mechanism, the traveling bodies move to the gathering position while maintaining the equal intervals by driving the cylinder. It was impossible to freely change the intervals after the movement of each traveling body by driving the cylinders.

[0004]

The problem to be solved is that when the conveyed products are sent to the next process, the conveyed products are in a collective state and cannot be arranged at arbitrary and constant intervals.

[0005]

SUMMARY OF THE INVENTION The basic structure of the present invention is to provide a plurality of holding control mechanisms for conveyed articles in a conveyed article aligning apparatus for aligning conveyed articles such as tile substrates at regular intervals. An interval adjusting mechanism that adjusts the intervals between the plurality of holding control mechanisms, and the plurality of holding control mechanisms and the interval adjusting mechanism are vertically movable via the elevating control mechanism and the reciprocating control mechanism and from one side to the other side. It is provided so as to be able to reciprocate over a period of time, and the intervals between a large number of conveyed product groups are arbitrarily set and arranged in a collective state.

[0006]

[Operation] By moving the holding control mechanism to one side and lowering it through the elevating control mechanism and the reciprocating control mechanism,
The conveyed goods group located on one side was held via the holding control mechanism, and the conveyed goods group held by the holding control mechanism was moved from one side to the other side by the reciprocating control mechanism and moved to the other side. The conveyed object group is adjusted at regular intervals by the interval adjusting mechanism, and then the held state of the conveyed object group is released, and the conveyed object group is aligned in the collective state.

A holding member 64 adjacent to the feeding member 66
Is fixed to the feeding member 66, and the reciprocating movement of the feeding member 66 acts on the holding member 64.

A pair of sandwiching piece support members 82 and 84 are provided so as to face each other between the lower end portions of both sides of the holding member 64. First guide shafts 92, 94 of a book are provided, and the first guide shafts 92, 94 are symmetrically fixed at one end to the sandwiching piece support members 82, 84 respectively and at the other end at the sandwiching piece. The supporting members 82 and 84 penetrate each of them and are further fixed to the holding member 64 (see FIG. 6).

Further, referring to FIG. 6, one end of the one first guide shaft 92 is fixed to the right supporting member 84 for the sandwiching piece, and the left end penetrates the supporting member 82 for the sandwiching piece and the left side of It is slidably supported by a holding member 64.

The other end of the other first guide shaft 94 is fixed to the left sandwiching piece support member 82, and the right end penetrates the sandwiching piece support member 84 and slides on the right holding member 64. It is movably supported.

In this way, the two first guide shafts 92, 9
4 is controlled so that the sandwiching piece support members 82, 84 for supporting the sandwiching pieces 88, 88, which will be described later, can slide by sliding from one side to the other side and from the other side to the one side. ing. That is, it is provided for the purpose of suppressing that one sandwiching piece does not slide but stands still.

Further, two second guide shafts 80, 80 for guiding are provided below the first guide shafts 92, 94, and both side ends of these second guide shafts 80, 80 are sandwiched by a pair. It penetrates the upper side of the piece support members 82 and 84 and is fixed to the lower end portions on both sides of the holding member 64 (see FIG. 6).

Further, a pair of support members 82, 84 for sandwiching pieces.
A cylinder 86 is supported on the inner side below, and one end of the cylinder 86 is projected to the outside of the sandwiching piece support member 84 and is connected to a rod (not shown), and the rod is a pneumatic mechanism. The cylinder 86 can be expanded and contracted by driving an air pressure mechanism.

In order to sandwich the tile base W, the sandwiching pieces 8 are provided below the pair of sandwiching piece supporting members 82 and 84, respectively.
8 and 88 are vertically provided, and cushioning members 90 are attached to the inside of these sandwiching pieces 88 and 88 so as not to damage the tile base W when the tile base W is sandwiched.

Therefore, when the cylinder 86 expands and contracts, the pair of sandwiching pieces 88, 8 attached to the pair of sandwiching piece support members 82, 84 constituting the holding control mechanism 62.
8 is the first guide shaft 92, 94 and the second guide shaft 80,
The spacing is adjusted from one side to the other side via 80, and the tile base W is sandwiched through the cushioning material 90 (see FIG. 7).

The structure of the holding control mechanism 62 is as described above, and 16 of the above-mentioned structures are arranged in a row as is apparent from FIGS. 4 and 5. However, of the 16 holding control mechanisms 62, one of the support plates 4
The above-mentioned feed member 66 is attached to one holding control mechanism 62 adjacent to the four side, and one holding control mechanism 62 adjacent to the other support plate 46 is fixed to the support plate 46.

In the specific example of the holding control mechanism 62 described above, the pair of sandwiching pieces 88, 88 attached to the pair of sandwiching piece supporting members 82, 84 widen or narrow the interval. Although the tile base W is held and the held tile base W is released, a so-called vacuum suction mechanism having a large number of suction cups may be adopted as the holding control mechanism instead of this embodiment ( See Japanese Utility Model Publication No. 52-23555).

The cylinder 86 is provided in each of the 16 holding mechanisms 62, and the cylinder 86 has been explained as a basic example to operate integrally. However, although not shown, the control of the cylinder 86 is controlled electrically or mechanically. Alternatively, each cylinder 86 may be operated independently. For example, the inventor also plans to suspend the operation of each of the 16 holding control mechanisms 62, or to suspend the operation of every two of them.

That is, in the case where the conveyed product supplied from the conveyor 12 is large, all the holding control mechanisms 6
It is necessary to consider that the operation of the holding control mechanism 62 can be suspended for every one or two in order to avoid the trouble that the two do not operate.

Next, the interval adjusting mechanism 71 will be described.
As shown in FIGS. 1 and 5, the gap adjusting mechanism 71 is for adjusting the gap between the holding control mechanisms 62 arranged in a row. That is, this is for setting the adjacent intervals of the tile base W groups held by the plurality of holding control mechanisms 62 to a desired interval and a set state and mounting them on the pallet 16.

Links are supported at the central portions of the upper surfaces of the respective holding members 64 adjacent to each other via pins 70, and a large number of links constitute a pantograph mechanism 72 as a whole. Therefore, since the plurality of holding members 64 are connected by the pin 70 and the pantograph mechanism 72, the holding members 64 are expanded and contracted according to expansion and contraction of the pantograph mechanism 72.
The interval between them is adjusted arbitrarily.

Of course, since the holding member 64 constitutes a part of the holding control mechanism 62 as described above, the space between the holding control mechanisms 62 is changed according to the movement of the holding member 64 in the left-right direction in the drawing. Needless to say, is set at an arbitrary interval.

Although it has been described that the feed member 66 moves in the axial direction of the guide bars 48, 48 by receiving the rotational force of the rotary shaft 50, its control will be described.

The rotary shaft 50 is rotated by the drive of the servo motor 60 described above, and the feed member 66 located on the side of the one support plate 44 is moved in the left-right direction in the drawing, thereby the pantograph. As a result of the mechanism 72 expanding and contracting, the intervals between the plurality of holding control mechanisms 62 are adjusted.

Guide rails 74 are provided along the support member 34 on both sides of the support member 34 beside the servo motor 60. The guide rails 74 are located near one support plate 44. A plurality of detection mechanisms 76 for detecting the position of the holding control mechanism 62 are provided.

A detection piece 78 is provided above the feed member 66, and the position of the holding control mechanism 62 is detected by the proximity of the detection mechanism 76 and the detection piece 78, and necessary information is sent to the servo motor 60. The holding control mechanism 62 is accurately positioned as a result, or the position of the detection mechanism 76 is changed as necessary.

Another configuration related to the present invention will be described with reference to FIG. On the base end side of the conveyor 12 for transportation,
Although it has been described that the clay kneader 15 is provided, another one for sending the tile base W cut by the cutter 17 to the conveyor 12 for conveyance is provided at the base ends of the clay kneader 15 and the conveyor 12 for conveyance. Is provided with a conveyor 19.

A finishing machine 21 for adjusting the shape of the cut tile base material W is provided on the base end side of the transfer conveyor 12.

In the above example, the holding control mechanism 62
The time for adjusting the interval of the tile base W group held by was explained after moving the tile base W group from one side to the other side, but the interval adjustment time is for the tile base W group. Not restricted after moving. In the aggregated state, the interval may be adjusted before the group of tile bases W held by the holding control mechanism 62 is opened, so the interval adjustment time may be during the rising of the group of tile bases W. However, it may be moving.

Next, the operation of the embodiment of the present invention will be described. The tile base material W extruded by the clay kneader 15 and cut into a certain size by the cutting machine 17 is edge-finished by the finishing machine 21 to obtain the tile base material W.

The group of tile base materials W, which has been subjected to edge finishing, is supplied to the conveyor 12 at regular time intervals, and 16 tile base materials W groups are mounted on the conveyor 12 at regular intervals. Then, the traveling carriage 20 is conveyed below the ascending / descending control mechanism 31 and the reciprocating control mechanism 39, which are a part of the configuration.

When a certain number of tile base materials W are conveyed below the traveling carriage 20 or the like, the holding control mechanism 62 located on the other side (for example, the sending conveyor 14 side) causes the lift control mechanism 31 and the reciprocating mechanism. It is moved to one side (for example, the conveyer 12 side) via the control mechanism 39, and is also lowered toward the tile base material W group located below.

Next, the holding control mechanism 62 holds the group of tile base materials W mounted on the conveyor 12 at regular intervals.

Then, the holding control mechanism 62 holding the group of tile base materials W together with the space adjusting mechanism 71 is lifted through the elevating control mechanism 31 and the reciprocating control mechanism 39, and is also located on the other side. It is moved toward the 14 side.

Therefore, the spacing of the tile base W group held by the holding control mechanism 62 is adjusted by the control of the spacing adjusting mechanism 71, and then the held tile base W group is controlled by the holding control mechanism 62. It is released from the holding control mechanism 62, mounted in a collective state on the pallet 16 of the delivery conveyor 14 on the other side with a constant interval, and delivered to the next process.

However, the interval adjustment time is not limited to after the tile base W group is moved, as described above,
It may be rising on one side, or may be moving from one side to the other.

[0063]

Since the present invention has the above-mentioned structure, it has the following advantages. Even if the type and size of the transported items are different,
It is possible to arbitrarily set the interval between the conveyed objects and arrange them in a gathered state as needed.
