Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sticking piece fastening device for fastening a decorative or naming sticking piece to a cloth.

[Conventional technology]

Conventionally, the above-mentioned sticking pieces are cut by a worker one by one from the material and fastened to a cloth. However, workability is extremely poor. Therefore, the applicant company has a cloth receiving surface for attaching a cloth, and a cutting rod insertion portion which is a material receiving surface for attaching the material of the attaching surface and penetrates from one surface to the other surface. Material receiving surface is provided in a state where the cloth receiving surface and the other surface of the material receiving surface are opposed to each other, further comprising a first cylinder, wherein the edge of the tip surface of the cylinder has a material of an attached piece. The cutting rod is cut from the side of the material receiving surface by the operation of the cylinder, and the cutting rod, which is the cutting edge for cutting the sticking piece from The present invention has devised and used a sticking piece fixing device which is connected so as to be able to move forward and backward to a position where the cloth reaches the cloth receiving surface through the portion.

[Problems to be solved by the invention]

However, in the above-mentioned apparatus, if a strong one is used for the cylinder so that the sticking piece can be reliably cut from the material even if the sticking piece is hard, the force of pressing the cut sticky piece against the cloth by the cutting rod also increases. However, there was a problem that a scratch was made on the cloth.

The present invention has been made in view of the above points, the purpose thereof is to perform the work of fastening the attached piece to the cloth with good workability, and even if the material of the applied piece is hard Provided is a sticking piece fixing device that can cut a sticking piece reliably from the material, and can press the cut sticky piece against a cloth softly to prevent damage to the cloth. It is.

[Means for solving the problem]

In order to achieve the above object, the present invention employs the means described in the claims, and the operation is as follows.

[Action]

The cutting rod is advanced by the first cylinder. When the cutting edge passes through the position of the material receiving surface during the forward movement, the force of the second cylinder is applied. At this time, the attached piece is cut from the material of the attached piece. The cut piece is carried toward the cloth on the cloth receiving surface by the cutting rod. In the process, the force by which the second cylinder advances the cutting rod disappears. After extinction, the cutting rod is advanced only by the first cylinder. When the sticking piece carried by the cutting rod abuts on the cloth on the cloth receiving surface, the sticking piece is pressed against the cloth by the cutting rod advanced only by the first cylinder.

In the course of the advance, the cutting edge 46
When the blade passes the position, the cutting edge 46 cuts the sticking piece from the material 58 (punching in the present example). The cut sticky piece is carried toward the cloth receiving surface 20 in a state where the cut sticky piece is sucked on the tip end surface of the cutting rod 33 by the suction effect through the suction hole 48. Then, the attached piece is pressed against the cloth 12a on the cloth receiving surface 20 by the pressing surface 47 at the tip end surface of the cutting rod 33. By this pressing, the heat of the cloth receiving surface 20 is transmitted to the adhesive provided on one surface of the attached piece through the cloth 12a and heated, and the attached piece is adhered to the cloth 12a with the adhesive. Thereafter, the cutting rod 33 is raised to the position shown in FIG. This completes the fastening of one sticking piece to the cloth 12a. Then feeder 59
, The cloth 58a is moved along the cloth receiving surface 20 by the operation of the driving device 7. The above operation is repeatedly performed, and a large number of attached pieces are successively fixed to the cloth 12a. The bonding may be performed by high-frequency bonding means or an adhesive applied to the attached piece.

Next, the first and second cylinders will be described with reference to FIGS.
The driving of the cutting rod 33 by the 31, 32 will be described in detail.
When the solenoid valve 52 is switched from the illustrated state, air from the compressor 53 flows into the first and second cylinders 31 and 32 from the respective ports 36 and 41. Thereby, the pistons 38, 43 in each cylinder advance in the direction of the arrow in FIG. 4 (a), and the cutting rod 33 advances accordingly. In this case, since the amount of air flowing out from the port 27 of the first cylinder is restricted by the restrictor valve 54, the piston 38 moves slowly. Therefore, as shown in FIG. 4 (b), the advancing / retracting rod 44 of the piston 43 is kept in contact with the piston 38 and both pistons 38, 43
Moves forward together. With the advance of the cutting rod 33 as described above, the distal end surface of the cutting rod comes into contact with the material 58 as shown in FIG. 4C, and the cutting edge 46 is separated from the material as shown in FIG. Cut 58a. In this case, as is clear from the figure, the cutting rod 33 is attached to each piston 38,
43 is driven forward by the combined force of each of 43, even if the material 58 is a hard material,
58a can be cut reliably. The cut attachment piece 58a is adsorbed and carried on the tip end surface of the cutting rod 33 as described above. As shown in FIG. 4 (e), the piston 43 of the second cylinder 32 finishes moving to the forward end in the course of the transportation, and thereafter the piston 43 advances only by the forward force of the piston 38 in the first cylinder 31. Drive. Then, as shown in FIG. 4 (f), the sticking piece 58a is pressed against the cloth 12a by the cutting rod 33 by the forward force of the piston 38. When the pressing is completed as described above, the solenoid valve 52 is switched again to the state shown in FIG. Then, the air from the compressor 53 flows into the first cylinder 31 from the port 37 through the check valve 55. As a result, the piston 38 retreats at a high speed to the position shown in FIGS. 3 and 4 (a), and the cutting rod 33 also retreats integrally. During this retreating process, the piston 38 is moved by the reciprocating rod 44 of the second cylinder 32.
The piston 43 is also retracted to the position shown in FIGS. 3 and 4 (a).

When operating the first and second cylinders 31 and 32 as described above, in this embodiment, both cylinders are connected to one control device 52.
Is connected to a fluid source 53 for driving. Therefore, the operation of both cylinders 31, 32 can be controlled only by the control of one control device 52. However, each of the cylinders 31 and 32 may be connected to an individual drive fluid source via an individual control device. Next, the second cylinder 32 includes a cutting rod 33.
Alternatively, a force for directly advancing it may be added. That is, the second cylinder 32 'is attached to the base 22, as indicated by the imaginary line in FIG. On the other hand, the cutting rod 33 has a receiving piece 64.
Is fixed with the fixture 65. Then, the tip of the advancing / retracting rod 44 'in the second cylinder 32' is opposed to the receiving piece 64. With this configuration, the second cylinder 32 'applies a force to advance the cutting rod 33 when the cutting edge 46 of the cutting rod 33 passes through the position of the material receiving surface 25. Can be.

Next, different embodiments of the present invention will be described. The third
In the illustrated circuit 51, the throttle valve 54 and the check valve 55 may be eliminated. In this case, the operation of each cylinder 31, 32 is as follows. Since the area of the piston 38 and the piston 43 is extremely small in the former (for example, 16φ in the former and 30 to 40φ in the latter), the piston 38 moves ahead of the piston 43 as shown in FIG. When the distal end surface of the cutting rod 33 comes into contact with the material 58, if the material 58 is hard,
Since it is not possible to punch out 58, the cutting rod 33 and piston 38
Stops at that position. Then, when the advancing / retracting rod 44 of the piston 43, which has advanced with a delay, comes into contact with the piston 38, the advancing forces of the pistons 43, 38 are combined to act on the cutting rod 33. And the sticking piece 58a is punched out of the material 58 by the force. Subsequent operations are the same as those described above. In order to reduce an impact sound when the advancing / retreating rod 44 abuts on the piston 38, it is preferable to attach a muffling member 61 made of an elastic material. Also, the main body of the second cylinder 32
It is preferable that a similar silencing member 62 is additionally provided on 40 so as to reduce the impact sound when the piston 43 collides therewith.

Next, FIGS. 7 and 8 show still another embodiment of the present invention, in which the example of FIG.
FIG. 8 shows an example in which a small-diameter portion 44b is provided at the distal end of the reciprocating rod 44.

〔The invention's effect〕

As described above, in the present invention, by repeatedly moving the cutting rod 33 forward and backward, the sticking piece 58
a, and the operation of pressing the attached piece 58a to the cloth 12a can be repeated one after another, and the effect of being able to stop the applied piece 58a one after another on the cloth 12a. is there.

Moreover, in the case where the sticking piece 58a is fixed, even when the sticking piece 58a is made of a hard material, when the sticking piece 58a is cut from the material 58, the force generated by the first and second two cylinders 31, 32 is used. It is characterized in that the sticking piece 58a can be reliably cut from the material 58 with a large force combined with.

In addition, even if the cutting is performed with such a large force, the second cylinder 32 has the cutting edge 46 of the cutting rod 33 attached to the sticking piece 58.
Since only a forward force is applied to the cutting rod 33 when cutting at a, when the cut sticking piece 58a is pressed against the cloth 12a, the force exerted by the second cylinder 32 on the cutting rod 33 is no longer present. There is also a feature that the cloth 12a can be prevented from being damaged in advance by being able to be pressed softly with only the force of the one cylinder 31.
