The sheet is folded in half in the width direction of the member 180. Furthermore, when the folding part 16 pushes the adhesive member 180 from above, the adhesive member 180 is attached to the upper part of the side plate 150C of the work 150.

  Specifically, in the tension generating unit 14, the sandwiching portion 56 sandwiches the adhesive member 180 of the portion adhered to the upper surface 50 A of the adhesive table 50 with the adhesive table 50. Therefore, the tension generating unit 14 generates a tension (5 to 10 N / 8 mm) in the adhesive member 180 when the folding unit 16 presses the adhesive member 180. Thereby, the non-adhesive surface of the adhesive member 180 contacts along the bent bending surface 30, and the bending surface 30 contacts the non-adhesive surface of the contacting portion so that the non-adhesive surface of the adhesive member 180 is convex. Fold it in half in the width direction.

  When the folding portion 16 is further moved downward, as shown in FIGS. 7 and 8, the pair of opposing surfaces 22 B and 24 B of the folding portion 16 are non-adhesive on the adhesive member 180 folded in half by the folding surface 30. The surfaces are brought into contact with each other to adhere the adhesive surfaces of the contacted portions. As a result, an adhesive portion 180A (see FIG. 10) in which the adhesive surfaces are adhered to each other is formed.

  When the folding portion 16 is further moved downward, as shown in FIGS. 8 and 9, the cutting blade 18 disposed so as to straddle the pair of opposing surfaces 22B and 24B adheres to the adhesion portion 180A The member 180 is cut in the width direction of the adhesive member 180. Thus, the folding unit 16 moves to the cutting position.

  Specifically, as shown in FIG. 14, since the fold portion 16 is formed with a recess 36 which is recessed relative to the other portion so as to straddle the pair of opposing surfaces 22B and 24B, The cutting blade 18 and the pair of opposing surfaces 22B and 24B are separated in the device depth direction. Thereby, the cutting blade 18 cuts the adhesive member 180 in a portion separated from the adhesive portion 180A in the width direction of the adhesive member 180.

  Here, the configuration of the folding portion 516 of the cutting device 510 according to the modification and the operation of the folding portion 516 will be described. First, the configuration of the folding unit 516 will be mainly described in terms of portions different from the folding unit 16. As shown in FIG. 18, the concave portion 36 is not formed in the folded portion 516, and the pair of opposing surfaces 522B and 524B extend to the intersecting surfaces 522C and 524C facing the front side in the device depth direction.

  Therefore, the cutting blade 18 cuts the end (the J portion in the figure) of the adhesive portion 180A. Therefore, the adhesive surfaces on the other side opposite to the side on which the adhesive portion 180A is formed with respect to the cutting blade 18 may adhere to each other.

  On the other hand, in the folded portion 16 of the present embodiment, as shown in FIG. 14, a recessed portion 36 recessed relative to the other portion is formed so as to straddle the pair of facing surfaces 22B and 24B. ing. For this reason, the cutting blade 18 and the pair of opposing surfaces 22B and 24B are separated in the device depth direction, whereby the cutting blade 18 cuts the adhesive member 180 in a portion separated from the adhesive portion 180A in the width direction of the adhesive member 180. Do. Therefore, adhesion of the adhesive surfaces on the other side opposite to the one side on which the adhesive portion 180A is formed with respect to the cutting blade 18 is suppressed.

  In this manner, when the adhesive member 180 is cut in the width direction of the adhesive member 180 (when the folding portion 16 reaches the cutting position), the control unit 130 controls the moving mechanism 40 of the moving unit 20 in the cutting device 10. As shown in FIGS. 9 and 10, the folding unit 16 disposed at the cutting position is moved to the initial position. Thus, the adhesive portion 180A of the adhesive member 180 is pulled out between the pair of opposing surfaces 22B and 24B, and is separated from the folding portion 16 in the vertical direction. The adhesive portions 180A do not adhere to the work 150 because the adhesive surfaces are adhered to each other.

  When the folding unit 16 moves to the initial position, the control unit 130 controls the motor 62 of the tension generating unit 14 in the cutting device 10 to open the pinching unit 56 in the closed position as shown in FIGS. 10 and 11. Move to the position. Thereby, the adhesion member 180 of the part adhered to the upper surface 50A of the adhesion base 50 is opened to the outside.

  When the pinching portion 56 in the closed position moves to the open position, the worker takes out the workpiece 150 from the gripping portion 110A of the workpiece gripping portion 110, and ends the series of operations. Subsequently, in the case where the adhesive member 180 is attached to another work 150, the adhesive member 180 is attached to the other work 150 by repeating the above-described operation.

  On the other hand, when peeling off the adhesive member 180 from the waste toner box 160 collected from the market, the worker can easily grasp the adhesive portion 180A and pull the adhesive member 180 (the adhesive portion 180A is not formed The adhesive member 180 is peeled off from the waste toner box 160 in a short time as compared with the case.

(Summary)
As described above, in the cutting device 10, the adhesive member 180 is folded in half in the width direction to adhere the adhesive surfaces to only the portion of the adhesive member 180 on the work 150 side (one side) with respect to the cutting blade 18 An adhesive portion 180A is formed.

  In addition, the folding portion 16 is formed with a recess 36 recessed relative to the other portions so as to straddle the pair of opposing surfaces 22B and 24B, and the cutting blade 18 and the pair of opposing surfaces 22B and 24B are formed. Are separated in the device depth direction. Therefore, as described above, compared to the cutting device 510 according to the modified embodiment in which the concave portion 36 is not formed in the folded portion 516, the side opposite to the side on which the adhesive portion 180A is formed with respect to the cutting blade 18 It is suppressed that the adhesive surfaces on the other side of the adhesive stick together.

  Further, in the cutting device 10, the adhesive member 180 is cut only by moving the folding portion 16 from the initial position to the cutting position.

  In addition, in the folding portion 16, the adhesive surface of the portion where the adhesive member 180 is in contact with the folding surface 30 for folding the adhesive member 180 in half and the non-adhesive surface of the adhesive member 180 folded in half by the folding surface 30 And a pair of opposing surfaces 22B and 24B for adhering the For this reason, the number of parts is reduced as compared to the case where the bending surface 30 and the opposing surfaces 22B and 24B are respectively formed on separate parts.

  Moreover, the cutting blade 18 is attached to the cross surfaces 22C and 24C of the folding part 16, and the recess 36 is formed on the cross surfaces 22C and 24C, so that the cutting blade 18 and the pair of opposing surfaces 22B and 24B are in the device depth direction. It is designed to be separated by Therefore, attaching the cutting blade 18 to a component separate from the folding portion 16 reduces the number of components as compared to the case where the cutting blade 18 and the pair of opposing surfaces 22B and 24B are separated.

  In addition, a tension generating unit 14 is provided which causes the adhesive member 180 to be in tension when the folding unit 16 presses the adhesive member 180. For this reason, the adhesive member 180 is cut without the worker gripping the part of the cutting blade 18 opposite to the work 150 side.

  In addition, by the adhesive member 180 being sandwiched between the adhesive base 50 and the sandwiching portion 56, tension is generated in the adhesive member 180. For this reason, the adhesive member 180 is cut more reliably than in the case where tension is generated in the adhesive member 180 simply by causing the adhesive surface of the adhesive member 180 to adhere to the adhesive base 50.
