[0002]
[Prior art]
7 and 8 show a conventional label tape 70 with release paper. In this label tape 70, an adhesive layer 72 is applied and formed on the back surface of the label base paper 71, and a thermosensitive color former layer (or non-heat sensitive agent layer) 73 is applied and formed on the surface of the label base paper 71. A label 74 is formed by applying a print 74 to a necessary portion on the agent layer 73, and these labels D are continuously pasted on a strip-shaped release paper 75. The label tape 70 is wound in a roll shape and supported by the shaft of the printing apparatus. Then, after the leading end is pulled out and necessary indications such as the expiration date and the production date are given to the thermosensitive color former layer 73 by a thermal head or the like, the label D is peeled off from the release paper 75, and the label D is peeled off. Affixed to products.
[0003]
However, in such a label tape 70, after the label D is affixed, the release paper 75 remains, which not only requires time and effort for disposal as waste, but also wastes resources. Therefore, a label tape has been developed in which labels are continuously connected without using the release paper 75. In such a label tape, there is an adhesive layer on the back side, so that when it is rolled up, the label surface is non-adhesive so that the outer label does not stick to the overlapping inner label surface. The material is coated. When using this label tape without release paper, a single-leaf label formed by cutting the label tape into a predetermined size for one label with a cutting device is guided to the transfer path and conveyed by a separate belt conveyor. It transfers to a to-be-adhered thing, for example, cardboard, and sticks.
[0004]
[Problems to be solved by the invention]
However, the label tape without release paper has a property that the single-leaf label is easily curled because the label surface is coated with a non-adhesive material as described above. For this reason, the single-leaf label after cut | disconnecting with a cutting device had the fault that it fell out from a transfer path | route, without being reliably guided in the said transfer path | route.
[0005]
In addition, when the curl remains on the single-leaf label even when it is fed out from the transfer path to the adherend and stuck to the adherend with the label sticking roller, there is a drawback that it is difficult to stick cleanly. The present invention has been made in view of such circumstances, and even if a single-leaf label obtained by cutting a label tape is curled, the single-leaf can be reliably guided to the conveyor and transferred, and the curl can be corrected during the transfer. An object is to provide a label transfer device.

At this time, since at least the surface of the transfer roller 82 on the cutter device 50 side is subjected to knurling 82A and 82B among the plurality of transfer rollers 82, the single-leaf label a is placed between the transfer roller 82 and the transport belt 29. It becomes easy to be invited.
[0020]
Further, the single-leaf label a sandwiched between the transfer roller 82 and the transport belt 29 is sandwiched and transported by the plurality of transport rollers 82 and the transport belt 29 and reliably transferred. Further, since the sheet is transferred while being nipped between the transfer roller 82 and the conveying belt 29, the curl of the single-leaf label a can be corrected during nipping and conveying. Thereby, when sticking the single-leaf label a on a to-be-adhered thing, it can stick beautifully.
[0021]
The single-leaf label a transferred by the single-leaf label transfer device is transported to the position of the label application roller 62 and sent onto a product (attachment) C or the like transported by a separate belt conveyor B or the like. Then, the single label a is pressed against the product C by the label applying roller 62. Therefore, the label a is securely attached to the product C.
[0022]
【The invention's effect】
