Description

  The present invention relates to a label co-up prevention apparatus and a co-up prevention method, and more specifically, a label co-up prevention capable of preventing a label from being peeled off together with an unnecessary sheet when the unnecessary sheet is peeled off from the release sheet. The present invention relates to a device and a joint rising prevention method.

  2. Description of the Related Art Conventionally, when forming a label, a technique is known in which a closed-loop notch is formed on an adhesive sheet temporarily attached to a strip-like release sheet via an adhesive layer using a die cutting device or the like. Then, the adhesive sheet region positioned inside the cut is used as a label, and the adhesive sheet region positioned outside the cut is used as an unnecessary sheet. The unnecessary sheet is peeled off from the release sheet by the unnecessary sheet collecting device, and is conveyed to the next step as a state in which only the label is adhered on the release sheet.

  In the unnecessary sheet collecting apparatus, there may be a case where a desired number of labels cannot be obtained due to a so-called co-up phenomenon in which the label is peeled off from the release sheet together with the unnecessary sheet. This is because the blade of the die cutting device or the like is chipped or worn, and the label is partially connected to the unnecessary sheet, or the adhesive layer between the label and the unnecessary sheet is formed after cutting by the die cutting device or the like. This is due to the fact that they adhere to each other.

  Here, as an apparatus for preventing co-up of labels, for example, there is one disclosed in Patent Document 1. Patent Document 1 includes a table and a plate that is provided on the table and folds back unnecessary sheets. In this document, when an unnecessary sheet is folded by a plate and peeled off from the release sheet, the label is urged toward the release sheet by the plate.

Japanese Patent Laid-Open No. 2002-1844

  However, in Patent Document 1, it is said that if the distance between the plate and the table is made too small in order to sufficiently exert the urging force to the label by the plate, the unnecessary sheet is rubbed with the plate tip and easily cut. There is an inconvenience. If the gap between the plate and the table is widened to eliminate such inconvenience, the biasing force to the label will be insufficient, so that the biasing force to the label can be maintained moderately and unnecessary sheets can be avoided from being cut. Inconvenience that it is very difficult to adjust the interval to achieve both. In addition, since it is necessary to perform adjustment work every time the adhesive sheet is changed, there is also a disadvantage that work efficiency is remarkably lowered.
