Description

  The present invention relates to a sheet sticking apparatus.

  2. Description of the Related Art Conventionally, there has been known a pasting apparatus that recognizes a single-piece label affixed to release paper with a sensor and affixes the label to an adherend (see, for example, Patent Document 1). In the sticking device described in Patent Document 1, a reflective sensor is used to detect a label.

JP 2008-114901 A

  However, since the labeling device described in Patent Document 1 uses a reflective sensor to detect the label, if the label is transparent, or if the label is the same color as the release paper, the label and release paper Is indistinguishable, and as a result, there is an inconvenience that the adhesive sheet cannot be attached. When a transmission type sensor is used instead of the reflection type sensor, there are the same disadvantages as the reflection type sensor. Although it is conceivable to use a contact sensor instead of the reflective sensor, the contact member of the contact sensor comes into contact with the label surface, which may damage the label surface or cut from the belt-shaped adhesive sheet. If the outer portion is not removed, there is a disadvantage that the step between the release paper and the label cannot be recognized.

  The present invention provides a sheet sticking device that can reliably recognize the position of an adhesive sheet with a simple configuration, accurately print a predetermined position in the adhesive sheet, and stick it to an adherend. is there.

  The printing unit 6 includes a thermal head 61 that is connected to the control unit 52 and performs printing on the adhesive sheet AS1, and a platen roller 62 provided to face the thermal head 61 with the raw fabric RS interposed therebetween. .

  The pressing means 8 includes a linear motion motor 81 as a drive device and an adsorption plate 83 fixed to the output shaft 82 of the linear motion motor 81. The suction plate 83 has a plurality of suction ports (not shown), and is configured such that the suction sheet AS1 can be sucked and held from the base sheet BS side by the suction ports.

In the above sheet sticking apparatus 1, the procedure for sticking the adhesive sheet AS1 to the adherend AH will be described.
First, the raw fabric RS is set as shown in FIG. Then, when the feeding means 2 drives the rotation motor 27 and feeds the original fabric RS, the processing means 4 drives the rotation motors 45 and 46 at a predetermined timing, and die cuts according to the speed at which the original fabric RS is fed. The roller 42 and the platen roller 44 are rotated. Along with this rotation, the cutting blade 41 forms a cut CU having a depth that does not penetrate the release sheet RL from the base sheet BS side, and forms a rectangular adhesive sheet AS1 inside the cut CU. Further, along with this rotation, heat is applied to the base sheet BS by the heater 43 disposed on the die cut roller 42, and the position where the heat is applied changes color and a mark MA is attached.

  Thereafter, when the original fabric RS is fed out, the mark MA is recognized by the sensor 51 and a signal to that effect is output to the control means 52. The control means 52 recognizes the position of the adhesive sheet AS1 based on the signal from the sensor 51.

  Thereafter, when the control means 52 determines that the adhesive sheet AS1 has reached the printable range of the thermal head 61 based on the recognition result of the sensor 51, the control means 52 controls the thermal head 61 to print on the adhesive sheet AS1. Do.

Then, when it is recognized by the sensor (not shown) that the leading end of the adhesive sheet AS1 in the feeding direction has reached the vicinity of the bent edge 72 of the peeling plate 71, the feeding operation of the original fabric RS is temporarily stopped. It will be in a standby state.
Next, when the adherend AH is transported on a transport path CV such as a conveyor, it is recognized by a sensor (not shown) and stops at a predetermined position below the suction plate 83. When it is confirmed that the adherend AH is stopped, the feeding means 2 drives the rotation motor 27 to feed out the raw RS, and by this feeding, the peeling sheet RL is bent by the peeling means 7 and the adhesive sheet AS1 is peeled off. The sheet RL is fed out from the bent edge 72 toward the suction plate 83 against the bending force of the sheet RL. When the adhesive sheet AS1 is sent out, the pressing means 8 drives suction means such as a suction pump or an ejector (not shown), and the adhesive sheet AS1 is sucked and held by the suction port of the suction plate 83.

  When the adhesive sheet AS1 is held by the suction plate 83, the pressing means 8 drives the linear motion motor 81 to lower the suction plate 83 and bring the adhesive layer AD of the adhesive sheet AS1 into contact with the adherend AH for adhesion. After pressing and sticking the sheet AS1 to the adherend AH, the suction means is stopped and the suction plate 83 is raised. When the adhesive sheet AS1 is attached to the adherend AH, each part is returned to the initial position. Thereby, the sticking of the peeled adhesive sheet AS1 to the adherend AH is completed, and thereafter the same operation as described above is repeated.

According to the above embodiment, the following effects can be obtained.
That is, since the mark MA different from the color of the base sheet BS is attached to the base sheet BS, even when the adhesive sheet AS1 is transparent or the same color as the release sheet RL, the cut CU at the time of forming the adhesive sheet AS1 There is no need to provide an image pickup means for confirming the shape.
For example, the position of the adhesive sheet AS1 can be recognized by the recognition means 5 such as a reflective sensor.
Furthermore, it is not necessary to prepare in advance the strip-shaped release sheet RL to which the adhesive sheet AS1 is attached at regular intervals, and the configuration is not complicated.
Moreover, since the mark MA is attached to the base material sheet BS when a closed loop cut is made in the belt-like adhesive sheet AS0, the configuration can be simplified and the application time can be shortened.
