Description

  The present invention relates to a system for inspecting peeling of a delivery body superposed by a releasable adhesive and an overlay delivery body.

  2. Description of the Related Art In recent years, a delivery body in which a surface on which concealment information is formed with a releasable adhesive such as a concealment postcard is press-bonded to the entire surface is frequently used. Such a sending body is required not to cause peeling until it reaches the recipient, while it must be easily peeled off when the delivered body is peeled off. In particular, even a slight peeling of the corners until reaching the destination owner leads to a full peeling, so that it is necessary to inspect and deal with a partial peeling such as a full peeling or a corner before the sending.

  Conventionally, as an inspection method for the glued state, air is blown on the glued flaps of envelopes, the unglueed parts of the flaps are forcibly raised, and the shadows caused by the rising are imaged with a CCD camera. It has been proposed to compare the imaged image data with a judgment criterion that has already been set using an image checker to judge whether the pasting state of the entire flap portion is good or bad (Patent Document 1).

  However, pressure-bonding with a releasable adhesive on a concealed sending body with information concealment requires no peeling during the sending path from the time of sending body preparation, but easy to peel off the overlapping sending body. Since it must be peeled off, it is adhered in a very delicate adhesive state in relation to the concealment information printing ink, and the state of peeling by photographing the shadow of the peeled portion as proposed in Patent Document 1 above There is a problem that the method of judging the problem is that, when the peeled surface is large or the peeled part is completely bent, a shadow does not occur and a judgment error occurs.

  Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to provide an overlay sending body peeling inspection system and an overlay sending body that can reliably determine any peeling state of the overlapping portion of the sending body. .

  In order to solve the above-mentioned problem, in the invention of claim 1, an inspection system for inspecting peeling of a corner portion of an overlap sending body in which at least two pieces are pressure-bonded all over with a re-peelable adhesive to conceal information. A crimping portion that superimposes the overlapping pieces to form the overlay sending body is provided in the transport path, and is provided on the downstream side of the crimping portion in the transport path and is transported. An imaging unit that captures an image of a corner portion of the overlay sending body, and imaging data received from the imaging unit, and compared with a color determination pattern stored in advance in the storage unit, And a control unit that includes a determination unit that determines whether or not the corner portion is peeled off.

  The invention according to claim 2 is an overlay sending body in which at least two pieces are entirely pressure-bonded by a re-peelable adhesive to conceal information, and the peeled state is overlapped at a predetermined corner of the overlay surface. A determination pattern mark to be identified with a color different from the opposite surface is formed.

  According to the present invention, at least two pieces are imaged at the corners of the overlap sending body in which the information is concealed by pressing the entire surface with an adhesive that can be removed again, and stored in advance in the storage unit based on the imaging data. Compared with the color judgment pattern, it is determined whether or not the corners of the overlapping sending body are peeled off, so that even if there is no shadow due to peeling of the overlapping parts of the sending body, peeling due to the difference in color It is possible to determine the state, and it is possible to reliably determine any peeling state.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a conceptual configuration diagram of a peeling inspection system according to the present invention. In FIGS. 1A and 1B, the peeling inspection system 11 includes a pressure-bonding section 13 that folds and crimps a piece with a predetermined pressure by a pressure roller in a conveyance path of a conveyance belt 12 constituting a part of the conveyance means. And an imaging unit 14 including a color sensor is provided on the upstream side of the crimping unit 13 in the transport path. The overlap sending body transported by the transport belt 12 will be described with reference to FIG. 3, but the system up to the crimping section 13, a paper supply section (not shown), a releasable adhesive application section, a cutting section, a folding section. Is provided.

  The imaging unit 14 captures the corners 21A and 21B of the superimposed sending body 21 being conveyed as shown in the illustrated imaging line, and the width direction of the transport belt 12 corresponding to the corners 21A and 21B ( It is provided at a position in the direction perpendicular to the transport direction.

  Next, FIG. 2 shows a block diagram of a control unit in the peeling inspection system. In FIG. 2, the control unit 31 includes a control processing unit 32, a reception unit 33, a determination unit 34, a storage unit 35, and a conveyance control unit 36.

  The control processing unit 32 controls the system as a whole, and includes a program for this purpose. Note that illustration of a memory developed for executing the program is omitted. The receiving unit 33 is an interface that receives imaging data from the imaging unit 14.

  The determination unit 34 identifies the colors of the corners 21A and 21B of the superimposed sending body based on the imaging data received by the reception unit 33, and compares it with the color determination patterns stored in the storage unit 35 in advance. Thus, it is determined whether or not the corners 21A and 21B of the overlap sending body are peeled off, and a program for this is provided. The color determination pattern stored in the storage unit 35 includes a color itself, a color pattern, a determination pattern mark (described in FIG. 3), and the like, and is stored according to the sending object to be inspected. The conveyance control unit 36 outputs a conveyance control signal for controlling conveyance of the conveyance means (conveyance belt 12).

  The determination result by the determination unit 34 is, for example, output as a determination output signal when the control processing unit 32 is abnormal (peeling occurs). For example, the determination result is picked up by a pick upper (not shown) provided on the downstream side. Or excluded and made to be remanufactured.

  Here, FIG. 3 shows an explanatory view of the overlay sending body to be inspected. In FIG. 3A, the overlay sending body 21 has an upper piece 22 and a lower piece 23 which are continuous at a fold line 24, and one side (the concealment information printing side) and the opposite side are colored (here, the color itself). However, it may be a pattern) (see FIG. 3C), a removable adhesive (removable adhesive) 25 is formed on the one surface, and this surface is formed on this surface. The concealing information (not shown) is printed, and the releasable adhesives 25 are overlapped with each other at the fold line 24 so that the entire surface is pressure-bonded. The corners of the continuous upper piece 22 and lower piece 23 of the sending body 21 become the corners 21A and 21B to be inspected when they are superimposed as shown in FIG.

  3B is basically the same as that shown in FIG. 3A, except that each corner of the lower piece 23 has a different color from the opposite surface of the overlapping surface. The determination pattern marks 26A and 26B to be identified are formed. The determination pattern marks 26A and 26B may be filled spot marks or pattern marks. These determination patterns are stored in the storage unit 35 of the control unit 31 for determination. Then, the corners 21A, 21B on which the determination pattern marks 26A, 26B are formed when the corners of the continuous upper piece 22 and lower piece 23 of the sending body 21 are overlapped as shown in FIG. Are to be inspected.

  In the present embodiment, the overlap sending body 21 has been described as two pieces, but three pieces may be overlapped in a so-called Z-fold. In this case, the inspection may be performed on the opposite corner of the other surface after performing the corner on one surface.

  FIG. 4 and FIG. 5 are explanatory diagrams of the peeling inspection state in the present invention. 4A shows a case where peeling occurs at one corner 21A of the overlap sending body 21 shown in FIG. 3A, based on the imaging data of the imaging line by the imaging unit 14. FIG. Thus, the determination unit 34 specifies the color (color itself) and determines whether the color is different from the determination pattern (color itself) stored in the storage unit 35. Here, a determination result that the colors are different is made, and the control processing unit 32 outputs a determination output signal. If no peeling occurs, the determination result is the same color.

  FIG. 4B shows a state where the corners 21A and 21B are peeled off, and the determination unit 34 performs the same determination process as in FIG. 4A.

  FIG. 5A shows a case where peeling occurs at the corner portion 21A of the overlap sending body 21 corresponding to FIG. 3B, based on the imaging data of the imaging line by the imaging unit 14. The determination unit 34 specifies the determination pattern mark 26A and determines whether or not the determination pattern mark is a determination pattern mark stored in the storage unit 35. FIG. 5B shows a state where the corners 21A and 21B are peeled off, and the determination unit 34 performs the same determination process as in FIG. 5A.

  Note that the color difference and the determination pattern mark are also applied to each of the overlapping sending bodies 21 corresponding to FIGS. It can be inspected by the same determination process as described above depending on the presence or absence of.

  In this way, even if there is no shadow due to peeling of the overlapping corner portion of the overlapping sending body 21, it is possible to determine the peeling state based on the difference in color, and it is possible to reliably determine any peeling state. Is.

  The overlay sending body peeling inspection system and the overlay sending body according to the present invention are used in the sending body manufacturing industry and the inspection apparatus manufacturing industry for inspecting the adhesion state of the information concealment sending body which is superimposed and pressure-bonded by the removable adhesive. Is possible.
