Description

  The present invention relates to a technology for managing the quality of envelopes that are used for direct mail and produced by an envelope bag making machine.

  One form of direct mail (DM) for individuals is to use an envelope for DM instead of a postcard, but the quality of the envelope for DM that encloses and seals a form on which personal information is printed If a defect is mixed, a form will be sent out from the DM envelope during mailing, leading to leakage of personal information. Therefore, it is necessary to make efforts to eliminate the defective quality of the DM envelope.

One way to prevent envelope quality defects is to install an inspection machine in the envelope bag making machine that produces the envelope, and to check the quality of the envelope produced by the envelope bag making machine online. As an apparatus for inspecting the quality of envelopes produced by an envelope bag making machine, Patent Document 1 discloses an envelope pasting portion inspection apparatus for inspecting the application state of glue applied to envelope paper.

  Certainly, an envelope produced by an envelope bag making machine by installing an inspection machine for inspecting specific quality defects, such as an envelope pasting part inspection device disclosed in Patent Document 1, in the envelope bag making machine. Although it is possible to detect specific quality defects (for example, poor gluing) that occur in the past, no data is available to identify the cause of the quality defect, so take fundamental measures to prevent quality defects. I couldn't.

  Furthermore, in order to prevent quality defects from being mixed into a DM envelope that encloses and seals a form on which personal information is printed, not only specific quality defects but also actions that lead to quality defects are It is necessary to notify the post-process what has occurred in the bag machine, but it was not considered to notify the post-process that an operation that led to poor quality occurred in the envelope bag machine.

  Therefore, the present invention can obtain data for specifying the cause of the quality defect of the envelope, and can notify the subsequent process that the operation leading to the quality defect has occurred in the envelope bag making machine. An object is to provide a quality control device for an envelope bag making machine.

The quality control device of the present invention that solves the above-described problems is a PLC (Programmable Logic Controller) in the control panel that controls the envelope bag making machine in the quality control device that manages the quality of the envelope produced by the envelope bag making machine.
