A well-known structure that can be fed intermittently in the direction of the arrow is used.

The operation of attaching a pasting strip to cloth using the pasting strip fixing device will be explained below. As the first and second cylinders 31 and 32 operate as described below, the cutting rod 33 passes through the insertion portion 26 from the position on the side of the material receiving surface as shown in FIG.
move forward towards. When the cutting edge 46 passes the position of the material receiving surface 25 during the forward movement, the cutting edge 46 cuts (punches in this example) the adhesive piece from the material 58.

The cut adhesive piece is carried toward the cloth receiving surface 20 while being sucked to the tip surface of the cutting rod 33 by the suction effect through the suction hole 48. Then, the sticking piece is pressed against the cloth 12a on the cloth receiving surface 20 by the pressing surface 47 on the tip end surface of the cutting rod 33. As a result of this pressing, the heat of the cloth receiving surface 20 is transmitted through the cloth 12a to the adhesive provided on one surface of the sticking piece, and the adhesive is heated, and the sticking piece is adhered to the cloth 12a with the adhesive. Thereafter, the cutting rod 33 is raised to the position shown in FIG. 2 by the action of the cylinder 31. As a result, one pasting piece of cloth 12a
The fixing is completed.

After that, the tape 58 is sent by the feeding device 59, and the cloth 1
The cloth 12a is moved along the cloth receiving surface 20 by the action of the driving device 7, and zero or more operations are repeatedly performed, and the cloth 12a
A large number of adhesive strips are attached one after another.

The above-mentioned adhesion may be performed using high frequency adhesion means or an adhesive applied to the adhesive piece.

Next, the driving of the cutting rod 33 by the first and second cylinders 31, 32 will be explained in detail with reference to FIG. 3.4. When the solenoid valve 52 is switched from the illustrated state, air from the compressor 53 enters the first and second cylinders 31.32 through their respective ports 36.41. This allows the piston 38.4 in each cylinder to
3 moves forward in the direction of the arrow in FIG. 4 (4), and the cutting rod 33 moves forward accordingly. In this case, since the flow rate of air from the port 37 of the first cylinder is restricted by the throttle valve 54, the piston 38 moves slowly. For this reason, as shown in FIG. 4 (bl), both pistons 38 and 43 move forward together while the advancing/retracting rod 44 of the piston 43 remains in contact with the piston 38. As the cutting rod 33 moves forward as described above, the As shown in FIG. 4 (C1), the tip of the cutting rod contacts the material 5S, and the cutting edge 46 cuts the pasting piece 58a from the material as shown in FIG. 4(d). In this case, as shown in the figure, Since the cutting rod 33 is driven forward by the combined force of the respective pistons 38, 43 of both cylinders 31, 32, even if the material 58 is a hard material, the pasting piece 58a can be securely attached. As described above, the cut adhesive piece 58a is carried while being attracted to the tip end face of the cutting rod 33. During the carrying process, the piston 43 of the second cylinder 32 is moved as shown in FIG. 4+81. In order to complete the movement to the forward end, the cutting rod 33 is then driven forward only by the forward force of the piston 38 in the first cylinder 31.Then, as shown in FIG. Accordingly, the pasting piece 58a is attached to the cloth 12a.
be forced to. When the pressing is completed as described above, the solenoid valve 52 is switched again to the state shown in FIG. 3. Air from the compressor 53 then flows from the boat 37 into the first cylinder 31 through the check valve 55. As a result, the piston 38 retreats at high speed to the position shown in FIGS. 3 and 4(a), and the cutting rod 33 also retreats together. In addition, since the piston 38 comes into contact with the advancing/retracting rod 44 of the second cylinder 32 during this retreating process, the piston 43 also moves as shown in FIGS.
It is moved back to the position shown in Figure +81.

When operating the first and second cylinders 31 and 32 as described above, in this embodiment both cylinders are operated by one control device f.
It is connected to a driving fluid source 53 via f52. Therefore, the operation of both cylinders 31, 32 can be controlled by only one control device W52. However, it is also possible for each cylinder 31, 32 to be connected to a separate drive fluid source via a separate control device.

Next, the second cylinder 32 may apply a force directly to the cutting rod 33 to advance it, i.e., as shown in phantom in FIG.
° is attached to the base 22. On the other hand, the cutting rod 33 has a receiving piece 64.
is fixed with a fixture 65. and the second cylinder 32°
The tip of the advancing/retracting rod 44'' is made to face the receiving piece 64. With this structure as well, when the cutting edge 46 of the cutting rod 33 passes through the position of the material receiving surface 25, it will not touch the cutting rod 33. The force that advances the second cylinder 3
It can be added by 2゛.

Next, different embodiments of the present application will be described. In the circuit 51 of FIG. 3, the throttle valve 54 and the check valve 55 may be removed. In this case, the operation of each cylinder 31, 32 will be as follows. Since the areas of the piston 38 and the piston 43 are extremely small (for example, the former is 16φ and the latter is 30 to 40φ), the piston 38 moves ahead of the piston 43 as shown in FIG.

When the tip of the cutting rod 33 comes into contact with the material 5B, the cutting rod 33 and the piston 38 cannot punch out the material 58 with only the force of the piston 38 if the material 58 is hard.
will stop at that position. When the advancing/retracting rod 44 of the piston 43, which has moved forward after a delay, comes into contact with the piston 38, the forward forces of both pistons 43, 38 are combined and applied to the cutting rod 33. Then, the adhesive piece 58a is punched out from the material 58 by this force. The subsequent operations are similar to those described above. In order to reduce the impact noise generated when the forward/retractable rod 44 comes into contact with the piston 38, it is preferable to attach a sound damping member 61 made of an elastic material to the main body 40 of the second cylinder 32. It is preferable to attach a similar muffling member 62 in order to weaken the impact sound when the piston 43 collides therewith.

Next, FIGS. 7 and 8 each show further different embodiments of the present application, in which the example in FIG. This shows an example in which the tip of the retractable rod 44 is provided with a narrow diameter portion 44b.

〔Effect of the invention〕

As described above, in the present invention, by repeatedly advancing and retreating the cutting rod 33, the sticking piece 58a is cut from the material 58 of the sticking piece, the sticking piece 58a is carried to the cloth 12a, and the sticking piece The operation of pressing the pieces 58a onto the cloth 12a can be repeated one after another, and the effect is that the pasting pieces 58a can be applied one after another to the cloth 12a.

Moreover, in the case of overlaying the pasting piece 58a, even if the pasting piece 58a is made of a hard material, the pasting piece 5
When cutting the material 58a, the adhesive piece 58a can be reliably cut from the material 58 using a large force, which is the combined force of the first and second cylinders 31 and 32.

Moreover, even with such a large force for cutting, the second cylinder 32 only applies forward force to the cutting rod 33 when the cutting edge 46 of the cutting rod 33 cuts the adhesive piece 58a. When pressing the pasting piece 58a onto the cloth 12a, the second cylinder 32 is no longer connected to the cutting rod 3.
3 is no longer exerted on the first cylinder 31
It also has the advantage that it can be pressed softly with the force of a chisel, thereby preventing damage to the cloth 12a.
