Description

  The present invention relates to a seal processing apparatus for producing a seal such as a label having an adhesive layer on the back surface, which is partially perforated.

  The seal is a sheet in which an adhesive layer made of an adhesive and a sealing base material are laminated on a release paper by cutting only the sealing base material and the adhesive layer without cutting the release paper with a half-cut blade. The desired outer shape is formed. By providing double half-cutting blades, a seal having a hole with a desired shape can be formed.

  Even if the adhesive is cut once, it adheres to each other. Therefore, when the formed seal is peeled off from the release paper and taken out, there may be a case where an unnecessary unnecessary portion is taken out together. If the sticking of stickers is automated, troubles will occur if such unnecessary parts are attached.

Therefore, Patent Document 1 describes a method in which an unnecessary portion is attached and hardly peeled off by ultrasonically heating the adhesive layer. Patent Document 2 describes a device that winds and removes unnecessary portions on the outer periphery of the seal in advance, but this method can remove only unnecessary portions on the outer periphery of the seal, Unnecessary parts inside cannot be removed.

  In order to solve the above problems, in view of the above problems, it is an object of the present invention to provide a seal processing apparatus capable of previously removing unnecessary portions inside a seal with a hole.

  In order to solve the above problems, a seal processing apparatus according to the present invention is capable of contacting and separating from a base that supports a sheet in which a release paper is adhered to a seal base material via an adhesive layer, and the base. A half-cut blade that cuts the seal base material to form an outer peripheral shape of the seal without cutting the release paper, and an inner side of the half-cut blade. And a full-cut blade that cuts the adhesive layer together with the release paper.

  According to this structure, the boundary of the seal | sticker outer periphery of a sealing base material can be cut | disconnected by a half cut blade, and the sealing base material of the part used as a seal can be cut | disconnected from the surrounding sealing base material. At the same time, the sheet can be cut at the boundary inside the seal by the full cut blade, and the unnecessary sealing substrate inside the seal can be separated together with the release paper. Thereby, before taking out the sealing part of a sealing base material from an outer peripheral part, the sealing base material inside a seal | sticker can be removed from a sheet | seat with release paper.

  Further, the seal processing apparatus of the present invention drives the pressure separation of the head to the base, the torque when the half-cut blade comes into contact with the sheet, and when the full-cut blade comes into contact with the sheet For example, a drive mechanism such as a mechanism using a two-stage cam may be provided.

  According to this configuration, cutting with a half-cut blade can be performed under optimal conditions, and cutting with a full-cut blade can also be performed under optimal conditions.

  Moreover, the seal processing apparatus of the present invention may include a separating unit that is provided inside the full-cut blade and pushes the seal substrate away from the full-cut blade.

  According to this configuration, it is possible to prevent unnecessary portions of the sealing base material inside the separated seal from adhering to the full-cut blade, and it is possible to perform continuous sealing die cutting.

  In the seal processing apparatus of the present invention, the full-cut blade may be a punch, and the base may be a die having a punch hole that meshes with the punch.

  According to this configuration, the seal substrate inside the seal can be removed together with the release paper from the sheet at the same time as the inside of the seal is cut off.

  Since the seal processing apparatus according to the present invention has a half-cut blade and a full-cut blade, the seal outer peripheral portion is cut by half-cut to keep the seal held by release paper, and at the same time with a full-cut blade. By cutting the inner peripheral portion of the seal, the excess seal substrate inside the seal can be removed together with the release paper. As a result, it becomes easy to take out only the necessary seal from the sheet, the efficiency of the sticking operation of the seal is high, and automation is also facilitated.

  Hereafter, the sealing processing apparatus 1 of one embodiment of this invention is demonstrated, referring drawings. FIG. 1 shows a seal sticking line 3 having a seal processing apparatus 1 and a sticking work robot 2 according to the present invention.

  The seal sticking line 3 forms a seal 6 with a hole by processing a sheet 5 supplied by pitch feeding from a sheet reel 4 with a seal processing apparatus 1, and a seal formed by the sticking work robot 2. 6 is taken out and adhered to a predetermined position of the product 7.

  As shown in detail in FIG. 2, the sheet 5 is a sheet in which a sealing substrate 10 is attached to the upper surface of a release paper 8 via a layer of an adhesive 9. The seal 6 is formed by cutting the seal substrate 10 together with the adhesive 9 into a desired hole shape.

  In the seal processing apparatus 1, a head 14 is disposed on a frame 12 provided on a base 11 that supports a sheet 5 supplied from a seat reel 4 so as to be moved up and down by an electric cylinder 13. The head 14 moves up and down along the slide guide 15 and moves so as to contact and separate from the base 11.

  The head 14 holds a Thomson blade (half-cut blade) 16 corresponding to the outer peripheral shape of the seal 6 on the bottom surface facing the base 11, and an implantation plate 17 having a hole in the center is attached. Further, the head 14 has a punch (full cut blade) 18 corresponding to the inner peripheral shape of the seal 6 and projecting downward from the Thomson blade 16 in the hole of the implantation plate 17, that is, inside the Thomson blade 16. Is attached. The punch 18 has a pressing member 20 urged by a spring 19 on the outer periphery thereof so as to protrude downward from the punch 18. Further, the punch 18 is provided with an air hole 21 that opens at the center of the tip thereof and that can eject compressed air. The base 11 is a table that supports the sheet 5 when the Thomson blade 16 bites into the seal substrate 10, and is a die in which punch holes 22 that correspond to the inner peripheral shape of the seal 6 and engage with the punch 18 are formed. is there. Non-adhesive treatment is applied to the outer periphery of the punch 18 and the inner periphery of the punch hole 22 so that the adhesive 9 is difficult to adhere.

  When the head 14 is lowered, first, the pressing member 20 comes into contact with the surface of the sheet 5, that is, the upper surface of the seal base 10, and the sheet 5 is fixed between the pressing member 20 and the base 11. Then, the punch 18 punches the seal substrate 10 together with the release paper 8. The descending speed of the head 14 during this period, that is, the driving speed by the electric cylinder 13 is about 100 mm / sec.

  Thereafter, the head 14 further descends at a speed of 5 mm / second, and the Thomson blade 16 bites into the seal substrate 10. At the same time, compressed air is ejected from the air holes 21 of the punch 18, and the sheet 5 pulled out from the front end of the punch 18 is forcibly pushed away from the front end of the punch 18 (separating means). The head 14 stops at a position where the Thomson blade 16 cuts the sealing base material 10 and the adhesive 9 layer, but the release paper 8 does not cut and slightly bites. The error of the stop position of the head 14 by the electric cylinder 13 is 0.02 mm or less.

  Then, the head 14 rises and is separated from the sheet 5. As a result, the sheet 5 has a layer of the adhesive 9 on the release paper 8, which is cut into a desired shape from the surrounding sealing base material 10 and the inner sealing base material 10 is removed into the desired shape. The seal 6 composed of the seal base material 10 and the excess seal base material 10 around the seal 6 remain.

  When the sticking line 3 takes out the seal 6 from the sheet 5 by the sticking work robot 2, first, the seal substrate 10 and the release paper 8 are each wound up by a winding device (not shown), so that the sheet 5 The release paper 8 is peeled off. Then, the seal substrate 10 with the adhesive 9 from which the release paper 8 has been removed is taken out by the suction head of the sticking work robot 2 only on the seal 6 portion on the receiving base 23 to which the adhesive 9 does not adhere. It is.

  The pitch feed amount of the sheet 5 for each elevation of the head 14 may be determined so that the interval between the seals 6 is wider than about 3 mm so that the excess seal substrate 10 can be continuously wound.

  In the present embodiment, since the outer periphery and the inner periphery of the seal 6 are cut by one head 14, there is no positional shift between the outer periphery shape and the inner periphery shape of the seal 6. Therefore, when the outer shape of the seal 6 is matched with the outer shape of the product 7 and pasted, the position of the hole in the product 7 and the position of the hole in the seal 6 exactly match.

  In this embodiment, since the seal substrate 10 inside the seal 6 is punched out together with the release paper 8 by the punch 18 and removed from the sheet 5, the seal 6 is removed from the sheet 5 by the sticking work robot 2. The surplus portion of the base material 10 is not taken out with it and does not cause trouble.

  If the seal base material 10 remains inside the seal 6, when the shape of the hole of the seal 6 is complicated, the seal 9 is sealed by the adhesive 9 when trying to pull the seal 6 away from the inner seal base material 10. The seal base material 10 in the inner peripheral portion 6 is pulled, which may lead to breakage or deformation of the seal 6. However, in the present embodiment, since the inner seal base 10 is removed from the seal 6 while accurately shearing the inner periphery of the seal 6 with the punch hole 22 and the punch 18, the seal base 10 is damaged or deformed. And the reproducibility of the shape of the hole of the seal 6 is high.

  When the sheet 5 is punched by the punch 18, the resistance of the electric cylinder 13 increases. Therefore, the electric cylinder 13 generates a larger torque than when only the sealing substrate 10 is cut by the Thomson blade 16. When the head 14 is used to drive with a cam instead of the electric cylinder 13, a two-stage cam may be used so that a two-stage torque can be generated.

  In the present embodiment, compressed air is used as the separating means for pushing and separating the sheet 5 punched into the punch 18, but a pusher protruding from the punch 18 may be provided inside the punch 18.
