Has a rectangular frame composed of four blades 15, 15, 15, and 15. The film sheet 2 can be pulled out to any linear shape. Since the die 8 is formed by combining an inexpensive blade 15 with a plurality of die sets 14, compared to a rotary blade made by cutting in the related art, it does not take much time to make by cutting, and the accuracy such as height adjustment is also easier. Can be manufactured at low cost.

As an inexpensive and general method of manufacturing a die, there is a method in which a groove is cut to a predetermined length by a saw or a laser, and a spring blade is embedded in the groove. It cannot be used when it is not possible to open the inside of the blade and press the inside of the blade as in the case where a suction head is provided. On the other hand, in the embodiment of the present invention, the blade 15 can be easily set on the die set 14 by dividing the blade 15.

The die 8 is a bottom part 1 of a base 17 of an attaching part 11 driven by a speed control motor (a label removing / conveying motor) 16 via a belt conveyor.
8 and linearly moves horizontally from the origin position to the sticking side as the base 17 moves horizontally. The conveying speed of the film sheet 2 and the films 10 and the moving speed of the die 8 are adjusted to the same speed, and the combined blades 15, 1, and 1 of the die 8 are adjusted.
It is desirable that the shape formed by 5, 15, and 15 and the dimensions of the extracted film sheet be the same. As shown in FIG. 9, a mounting portion 27 of the sticking cylinder 21 is provided on the upper surface of the base 17, and the sticking cylinder 21 is mounted on the mounting portion 27 so as to be able to move up and down.

Inside the die 8, there is a space 20 for the suction head 19. In this space 20, the suction head 19 connected to the lower part of the sticking cylinder 21 of the sticking part 11 is attached.
The suction head 19 moves horizontally together with the die 8 until the peeled film 10 is peeled off at the peeling edge 12, and the peeled film 10 is vacuum-adsorbed and held before peeling and then peeled. After peeling, the films 10 pulled out by the lowering of the application cylinder 21 on the application side
Can be attached to the adherend 7. That is, since the removed films 10 are adhered to the adherend 7 after being peeled off from the backing paper, the glue does not adhere to a device (roller) for transporting the film sheet 2 or a removing device (platen shaft). Since the suction head 19 is separate from the die 8 and is not baked, it is easy to form a suction hole. The die set 14 of the die 8 is provided with a hook block 23 that comes into contact with a hook pin 22 of the platen shaft 9 described later.

As shown in FIGS. 4 and 8, the platen shaft 9 combined with the die 8 for pulling out the film sheet 2 has a D-cut surface 24 and a torsion spring 25 for rotation on one end. A hook pin 22 is provided at the other end, and the hook block 23 of the die 8 comes into contact with the hook pin 22 so that the platen shaft 9 rotates against the rotational force of the torsion spring 25. It is composed.

Therefore, there is a distance between the film sheet 2 and the surface of the platen shaft 9 until the hooking block 23 of the die 8 comes into contact with the hooking pin 22 and the platen shaft 9 rotates. When rotation is started, the eight cutting dies and the film sheet 2 approach the platen shaft 9, and the film sheet 2 can be pulled out to a required shape. Blades 15, 15, 1 of die 8
5 and 15 adjust the axial position of the platen shaft 9 so as to approach the distance of cutting the film 10 while leaving the mount 3 on the surface of the platen shaft 9, and the line position or the point contact with the film 10 is predetermined. Films 10 in the shape of
Only to be able to overtake. Therefore, even a thin film can be pulled out by adjusting the axial position of the platen shaft 9.

At the same time as the pulling is completed, the contact between the hook block 23 and the hook pin 22 is released, and the platen shaft 9 is returned to the original position by automatically rotating in reverse by the torsion spring 25 for rotation. Film sheet 2
Is on the D-cut surface 24 so that the film sheet 2 does not come off when the die 8 returns to the origin side.

A peeling edge 12 is provided in the vicinity of the platen shaft 9. The peeled film 10 is bent at an acute angle by the peeling edge 12 so that the film 10 can be peeled off from the backing paper 3. Further, a work transfer unit 13 for transferring the adherend 7 obliquely below the platen shaft 9 is provided, and by lowering the sticking cylinder 21, the films 10 pulled out and separated and held by the suction head 19 are efficiently removed. It is configured so that it can be stuck to the adherend 7 well.

Next, how to use the film sticking apparatus shown in the embodiment of the present invention will be described with reference to the flowchart shown in FIG. 10 and FIG. FIG. 10 is a flowchart in the case where the films are labels, and FIG.

Shows a state in which it is located on the sticking side after finishing, and (e) shows a state in the middle of returning to the origin side.

First, the film sheet 2 is set on the supply reel 4 of the sticking device 1, and the leading end of the film sheet 2 is pulled out and transported by rollers, the platen shaft 9, the peeling edge 12, the capstan roller 26 and the pinch roller 27.
Then, it is wound around the take-up reel 5 and set. At this time, as shown in FIG. 4A, the platen shaft 9 has the D-cut surface 24 facing upward, and even if the films 2 pass over the D-cut surface 24, the rotation of the torsion spring 25 causes the platen shaft 9 to rotate. The platen shaft 9 does not rotate, and the D-cut surface 24 remains facing upward.

When a start instruction is given after the film sheet 2 is loaded, the speed control motor 16
Is turned on, the film sheet 2 is conveyed, and the base 17 of the sticking unit 11 moves toward the platen shaft 9 together with the die 8.

Eventually, the hook block 23 of the die 8 comes into contact with the hook pin 22 of the platen shaft 9 to rotate the platen shaft 9 against the rotational force of the torsion spring 25 for rotation. When the platen shaft 9 rotates, FIG.
As shown in (b), the blades 15, 15, 15, 1
Numeral 5 approaches a distance (adjusting the axial position of the platen shaft 9 in advance so that the film 10 is cut) while leaving the mount 3 on the surface of the platen shaft 9 and drawing a line on the film 10. Figure 4 with continuous contact or point contact
As shown in (c), only the films 10 can be pulled out into a predetermined shape.

Since the film 10 can be pulled out into a predetermined shape and held by the suction head 19 at the same time, even if only the films 10 are peeled off the backing paper 3 by the peeling edge 12,
There is no displacement. According to the flowchart of FIG. 10, the suction valve 19 is turned on at the same time as the start, according to the flowchart of FIG.
, The conveying speed of the film sheet 2 and the die 8
By adjusting the moving speed of the substrate to the same speed, it is possible to carry out peeling without causing a positional shift even if the suction is performed before peeling.

FIG. 4 shows that the die 8 has passed the peeling edge 12.
When reaching the sticking side as shown in (d), the position is confirmed by a labeling blade sticking position sensor (not shown),
The clutch is turned off, the speed control motor 16 is turned off, and the horizontal movement of the attaching section 11 stops.

When the moving of the sticking section 11 in the horizontal direction is stopped, the vacuum switch is turned on and the sticking cylinder 21 is lowered if the pulled film 10 is securely sucked by the suction head 19, and the work transport unit is moved. The film 10 is attached to the 13 adherend 7.

After the application is completed, the application cylinder 21 moves up to its original position. When the sticking cylinder 21 has finished ascending to the original position, the clutch is turned on, the speed control motor 16 rotates in the reverse direction, and the sticking part 11 and the die 8 return to the original origin position as shown in FIG. Move horizontally and return.

When the speed control motor (label removal / conveyance motor) 16 is turned off, the stepping motor 30 is turned off in parallel with the attaching step.
At N, the film sheet 2 slightly returns. This is to reduce the amount of wasted film sheet 2 by reducing the pitch between the films to be removed.

At this time, the platen shaft 9 returns to the original position by the action of the torsion spring 25 for rotation, that is, the D-cut surface 24 comes directly above, and the film sheet 2 returns through the D-cut surface 24 (see FIG. 4 (d)), the die 8 also takes the position on the D cut 24 and returns to the origin position, so that the film sheet 2 and the films 10 are not cut.

According to the film sticking apparatus 1 of the embodiment of the present invention, the process of removing the films 10 into a desired shape and the step of attaching the removed films 10 to the adherend 7 are performed in a continuous process. It can be performed efficiently (efficiently), and the peeled film 10 is peeled off from the backing paper and attached to the adherend 7, so that the glue adheres to the device for transporting the film sheet 2 or the device for removing the film sheet 2. There is no.
