Description

  The present invention relates to a concealment seal for a peeling device that can be peeled off using an automatic peeling device.

  Personal information (eg, address, name, age or questionnaire response) may be written on a postcard or other delivery. In such a case, it is now common practice to conceal the personal information part by sticking an adhesive concealment seal called a “protective seal” or the like on the personal information part.

  Postcards or other deliverables (collectively referred to herein as postcards) in which such personal information portions are concealed by a concealment seal are mailed or delivered, and the contents of the described information In order to confirm the above, an operation for removing the concealment seal is performed at the mailing address or the shipping address. Conventionally, such an operation for removing the concealment seal has been performed manually by an office worker.

  Opportunities for using such leaf documents in which the personal information portion is concealed by the concealment seal tend to increase year by year with the enforcement of the Personal Information Protection Law in recent years. The work of removing the concealment seal of the leaf document in which the personal information portion is concealed by the concealment seal cannot be dealt with only by the manual operation by the clerk. For this reason, the use of an automatic peeling-seal device that separates a leaf document to which such a peeling seal has been attached into a peeling seal and a leaf document body is increasing.

  As the peel seal automatic peeling apparatus, for example, an apparatus having a configuration as shown in FIG. In the peeling seal automatic peeling apparatus as shown in FIG. 7, the leaf document (32) supplied with the concealment seal supplied to the leaf document supply unit (31) is indicated by an arrow in the transport unit (33). And is supplied to the separation and separation unit (34). In the separation and separation unit (34), the leaf document body is held by the leaf document holder body (35) of the leaf document (32) to which the concealment seal is applied, and the release seal is concealed by the concealment seal. It is held in the trunk (36). Then, the body seals (35) and (36) rotate in the directions of the arrows in FIG. 7, whereby the peel seal is peeled from the main body of the leaf document. The peel seal thus peeled off is wound up and collected from the concealment seal gripping body portion (36) by the concealment seal winding portion (38). The leaf document body is collected by a separate collection mechanism (37) provided separately.

  In the case of using the peeling seal automatic peeling apparatus as described above, it is important that the leaf document main body and the peeling seal are suitably peeled at the peeling and separating unit (34). For example, when the adhesive strength of the peel seal is very strong, it is difficult to peel the peel seal using such a peel seal automatic peeling device. On the other hand, when the adhesive strength of the peel seal is very weak, there is a possibility that the peel seal may be peeled off from the leaf document when the leaf document is mailed or delivered.

  The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a concealing seal for a peeling device that can suitably peel the peeling seal from the main body of a leaf document using an automatic peeling seal peeling device. It is to provide.
