METHOD AND DEVICE FOR IDENTIFICATION OF PAPER ROLL

The present invention relates to a method and apparatus for attaching a tag to a core of a material web reel, such as a paper roll, and to writing and reading the tag information. This invention relates to a previous invention, patent application FI20040808.

At paper mills, the mill's information system must always be aware of each of the 10 cores and paper rolls in the production process. If a roll cannot be recognized, it must be stopped during the normal production process. The tag primarily tells which roll or sleeve is involved. Other information related to the roll, such as dimensions and weight, may also be included in the tag, or may be found by the tag in the factory data system. Identification, using 15 order numbers, is known at what stage the order is going.

There are several types of tags and systems in use. In some cases, the ink jet is marked with an ink jet on the outer surface of the jacket, or the cartridge identification information is transferred to the # # * ·: · winder by completely manual methods. Ink jet marking is • »ΙΦ x • · m: V 20 readable between sleeve manufacturing station - winder. With the winder, the paper web obscures the label, and the paper roll needs to be re-labeled. Initially, you can • · · attach a barcode sticker to the end of the roll and / or create an inkjet · · · label. When packing a roll, a label printed by a laser printer, for example, is attached to the packaging s V:

A major problem with known solutions is the use of multiple tags. This results in the need for multiple, duplicate writing and reading devices. Some of these also need to be moved, which requires commercial equipment.

5 Radio identification technology largely solves the problems described above by reducing the number of tags. Radio tags, called RFID tags, are still expensive, but their price trend is declining. The radio tag, the so-called tag, is preferably affixed to the sleeve, near the end of the reel. Both writing and reading of the tag is performed by a transceiver 10 called a tranceiver. The Tranceiver antenna is positioned so that the impact area extends as far as the tag. Writing means transferring information to an identifier, and reading means transferring information from an identifier

The object of the invention is to reduce the problems associated with known solutions, in particular by reducing the number of tags. Even at the core manufacturing station, the tag attached to the core can still be read even after the winder. The RFID tag can be read and / or written without light beam or direct contact. The RFID port is capable of recognizing the entire contents of the load being transferred * # t; j · automatically, without having to read the rolls one by one.

Figure 2 is a sectional view of a sleeve according to one embodiment of the invention.

Figure 3 is an end view of the sleeve of Figure 2.

Fig. 4 shows an end view of a sleeve with a stopper.

In the system of Figure 1, the tag mounting apparatus 3 is disposed adjacent to the core preparation area 5 as described in patent application FI 20040808. The sleeve preparation area covers a system in which the lengths of paper rolls 10 are cut from the parent sleeves and, if necessary, the ends of the sleeves are machined and / or provided with plugs and / or the like.

The tag mounting apparatus 3 has means for attaching the tag, RFID tag 2, or barcode label 9, to the sleeve 1. The tag mounting apparatus 3 is preferably located on one end of the sleeve preparation track at its last position. The mounting apparatus, in a preferred embodiment thereof, comprises means for detaching the tags 2 from the web 10 and means for attaching the tag 2 to the sleeve 1 by means of mangling, compression and / or gluing. The tag is attached to one end of the sleeve 1, after which it ·· · ί 20 is most preferably read. In the case of RFID tag 2, both the writing of the * identification information to the tag and the number of information contained in the tag ·· «^ • • i *, ·· * is performed by tranceiver 4. The sleeve 1 can then be transported to the ·« · 'winder. In Fig. 1, the sleeve ID is in the tag mounting position and previously: · · v: the treated cores IA, IB and 1C are on a conveyor 6 which moves the prepared cores • · * * · '···' out of the core preparation area 5 and is further transferred to the winder.

• · t · t: Prepared cores can also be delivered to the winder in wagons or • * "equivalent.

• · • t * ** *: Figures 2,3 and 4 illustrate embodiments associated with tag placement.

The tag, either based on a barcode or RFID, is attached to the mount 7, 4 119055, for example, on a wafer which is most preferably cup-shaped or square with folded corners or the like. The fastener may be made of paper, cardboard, plastic or the like. On sockets fitted with a plug 8, the tag is attached to the plug.

The preferred positioning of the disc 8 is at a depth within which the inch of the winder barely reaches. With a depth of just a few centimeters, the tag is still readable. This barcode tag can be read automatically even after the winder, right down to the packaging. The RFID tag is 10 readable and / or writable even after packaging and even in the customer process.

Within the scope of the invention, solutions other than those described above may be contemplated. For example, the location where the tag is installed may vary from what is described. However, it is essential that the installation takes place before the sleeve is removed from the sleeve preparation area, which can cover a wide area including the conveyor 6.
