Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an attachment machine for attaching studs to clothing fabric, and particularly relates to an attachment machine for attaching directional parts such as triangular studs to be attached to the opening corners of pockets. It is something.

BACKGROUND OF THE INVENTION Normally, a component mounting machine feeds upper parts such as rivets and lower parts such as washers sent from a chute to a crimping punch and a crimping die using a pusher mechanism that reciprocates, and the crimping bunch The crimping die is adapted to crimp the clothing fabric interposed between the crimping die and the crimping die.

If the tacks are non-directional, you can simply push the tacks along the guide groove, but as shown in Figure 12, triangular tacks attached to the opening corners of clothing pockets or tacks with directional properties on the surface can be used. If the button is decorated with certain characters, symbols, patterns, etc., the stud or button must be set in the crimping punch with the stud or button facing in the specified direction.

Conventionally, the direction setting mechanism that can determine the direction of a stud or button has been to rotate the button in a guide groove while pushing it with a pusher, and then use a tab formed on the back side of the button head to engage the pusher. The button is oriented in a certain direction by being latched onto the metal, and the caulking die is fed to the rotating positioning head, and by rotating the positioning column of this head by a certain angle, the button is oriented in a certain direction. Japanese Patent Publication No. 59-11682 discloses a button mounting device oriented in the direction of the button. The orienting means of this conventional device connects a pinion to the positioning column via a coupling element such as a universal joint, and the pinion is driven by a rack that is reciprocated by an air cylinder.

Problems to be Solved by the Invention However, in the conventional device described above, the lower part set on the crimping die side is rotated by a certain angle to orient it in a predetermined direction, and the upper part set on the crimping punch side It does not rotate in a predetermined direction. In order to rotate the upper part on the crimping punch side by a predetermined angle, the crimping punch side must move up and down, and if the lower end of the punch contacts the clothing fabric and then rotates, it will damage the fabric and the parts. This poses a problem in that the fabric may be rotated, which may pose a danger to the worker. Furthermore, as shown in Fig. 12, with triangular rivets, etc., it is necessary to rotate and tighten one rivet, but there are cases where the other rivet does not need to be rotated. There was no device that could do both, which was inconvenient.

The present invention has been made focusing on the above problems, and includes:
Equipped with a direction setting device that does not damage the triangular studs or directional upper parts of the clothing and upper parts and is safe for the worker, and can also be used when there is no need to change the direction of the upper parts. The purpose of this invention is to provide a parts mounting machine.

Means for Solving the Problems According to the present invention, the above-mentioned problems are solved by forming a gear in the pocket holder of the punch mechanism in a parts attaching machine that caulks and attaches a component to a fabric using a punch and a die of a punch mechanism. , a rack operating mechanism having a rack that meshes with the gear is provided, and when the component is rotated at a predetermined angle and crimped onto the fabric, an upper pusher is provided that sets the component in the pocket of the pocket holder when the punch mechanism descends. After retreating from the lower end of the descending pocket holder, the pocket holder is rotated by a predetermined angle due to the retreat of the rack, and
After the rotation of the pocket holder stops, the punch mechanism comes into contact with the fabric, and when the punch mechanism rises, the pocket holder of the punch mechanism is placed above the fabric, and the pocket holder rotates at a predetermined angle, and the parts are removed. If there is no need to rotate the pocket holder, this can be solved by providing a component mounting machine characterized in that a slideable stopper is fitted into a notch formed in the pocket holder to prevent rotation.

Pocket holder (18) that constitutes the working punch mechanism (10)
) is rotated by a predetermined angle by the rack (23) of the rack operating mechanism (2B) during the descent of the punch mechanism (10), and after the pocket holder (18) stops rotating, it contacts the fabric and punches the part (16). Attach it to the fabric using the die (35). After attaching the parts, after the punch mechanism (10) is separated above the fabric, the pocket holder (18) rotates at a predetermined angle and the punch mechanism (10) rises, so there is no risk of damage to the fabric or to the operator. dangers are prevented. In addition, if it is not necessary to rotate the component to attach it to the fabric, the rotation of the pocket holder (18) can be prevented by fitting the stopper (24) into the flat notch (61) formed in the pocket holder (18). blocked.

Therefore, two operations can be performed with one component mounting machine.

The rotation rod (3) is provided with a rack operating mechanism (26) that advances and retreats the rack (23) via a rod (25).
) are connected. Further, the rotating rod (3) is provided with a pin (27) made of a bolt so as to be adjustable. A rotatable lever (28) is rotatably supported on the shaft (4), and the lever (28) is connected to the pin (27).
) is fitted with a roller (29) that comes into contact with the rotary rod (3).
The rotation of the pin (27) causes the rotation of the pin (27). And shi/(-(2g) is normally biased clockwise by a tension coil spring (3o). Also, at the lower end of the lever (28) there is a connection from the chute (31) to the upper button shear guide (32). A rod (34) is connected to reciprocate an upper pusher (33) that sets the upper part sent into the pocket (19), and
A lever (37) is connected to the die (35) for reciprocating a lower pusher (36) for setting the lower part.

The rack actuating mechanism (26) is connected to the other end of the rod (25) which is connected to the pivot rod (3), as shown in detail in FIGS. 5 and 6. 1 connecting plate (
40), and a second connecting plate (41) that fits and interlocks with this.
The second connecting plate (41) and the bolt (42) connect the disc spring (
The rack (2) is frictionally coupled via the rack (43)
3).

As shown in FIG. 6, the first connecting plate (40) includes:
The convex portion (45) is formed by forming the concave portion (44). Further, the second connecting plate (41) has a convex part (47) formed by forming a concave part (48) at a position facing the concave part (44), and the first connecting plate (40) and the second connecting plate (41) are connected to each other by fitting the convex portions (45, 47) into the respective concave portions (44, 48).

Then, in a state where the first connecting plate (40) and the second connecting plate (41) are fitted and connected, a play of a distance (D) is formed between both the convex portions (45, 47). There is. Also the second
The connecting plate (41) is provided with a long hole (48) at a position opposite to the four parts (4B). The second connecting plate (41) and the rack (23) are connected by a clamping force through this elongated hole (48) by a bolt (42) and a disc spring (43), which is larger than the frictional force caused by this clamping force. Press the second connecting plate (41
) can slide within the elongated hole (48).

The side plate (50) that constitutes a part of the upper pusher guide (32) is pivotally supported by a bin (51), and the upper parts fed from the chute (31) are passed through the upper pusher guide (32). 32) is rotatable so that if it jams, it can be removed.

Next, the operation according to the present invention will be explained based on FIGS. 2 to 11.

First, if there is no need to rotate the upper part, push the stopper (24) to the left along the guide groove (62) against the compression spring (64) with your finger as shown in Fig. 4, and remove the pocket holder (18). into the notch (61). Then, as shown in FIG. 3, the stopper fixing lever (65) is pushed down by the compression spring (68), and the lower end of the stopper fixing lever (65) is pressed down to the stopper (24).
the stopper (24).

Since the stopper (24) and the notch (61) of the pocket holder (18) fit together, the pocket holder (18) is prevented from rotating by the stopper (24).

If it is necessary to rotate the upper part by a predetermined angle and tighten it to the fabric, push the stopper fixing lever (65) upward with your finger as shown in FIG.

Then, the compression spring (64) returns and the stopper (24)
) is moved outward to the state shown in Figure 4, and the stopper (24) and the notch (18) of the pocket holder (18)
61) is disengaged, and the pocket holder (+8) becomes rotatable. Therefore, the second crimping device can be used both when the upper part needs to be rotated and when it does not need to be rotated.

Next, the operation of rotating the pocket holder (18) will be explained. When the air cylinder (1) operates, the piston rod (2) rises and the rotating rod (3) rotates counterclockwise. and a rod (25) connected to the rotating rod (3)
, the first connecting plate (40) moves to the right in FIG. 6 by the play distance (D), and as shown in FIG.
The convex portion (45) of the connecting plate (4o) collides with the convex portion (47) of the second connecting plate (41). At this time, the upper pusher (33) on the lever (28) also moves to the right, and the tip (33a) of the upper pusher (33) retreats from the crimping part.

During this operation, the bottle (11) of the rotating rod (3)
) is not in contact with the impactor (12) of the figure 5 lever (6), so the figure 5 lever (6) does not rotate, and therefore the punch (1
6) does not descend. That is, before the punch (16) starts its downward movement, the tip (33a) of the upper pusher (33)
is set back from the caulking part to ensure work safety.

When the rotating rod (3) further rotates from the state shown in Fig. 7, the bottle (11) of the rotating rod (3) and the impactor (12) of the figure 5 lever (6) come into contact with each other, and the figure 5 lever (6) is the rotating rod (3)
The punch mechanism (10) rotates as the punch mechanism (10) rotates, and the punch mechanism (10) begins to descend via the rod (7) and toggle link (9). At the same time, the first connecting plate (40) further moves, and since the convex portions (45, 47) of the first and second connecting plates (40, 41) are in contact with each other, the second connecting plate (41) slides to the right as shown in Figure 8, and since the rack (23) is frictionally connected to the second connecting plate (41), it moves backward to the right in conjunction with the second connecting plate (41). do. Then, the pocket holder (18) that is engaged with the rack (23) is rotated by a predetermined angle, that is, 90 degrees, and the pocket holder (18) is rotated by a predetermined angle, that is, 90 degrees,
Rotate the upper part set 90 degrees to set it in the correct position. In other words, by rotating the upper part by a predetermined angle while the punch mechanism (10) is not fully lowered, the inconvenience of damage to the fabric or danger to the operator due to the rotation of the punch mechanism (10) can be avoided. are doing.

A stopper (24) is located at a position where the pocket holder (18) rotates by a predetermined angle (FIG. 4), and this stopper (24) prevents the pocket holder (18) from rotating. Figure 9 shows the rotating rod (3
) is rotated. That is, by preventing rotation of the pocket holder (18), the rack (23) is also prevented from retreating. However, as the rotation rod (3) rotates, the second connecting plate (41) moves along the long hole (48) against the frictional force of the disc spring (43), and the punch mechanism (1) moves along the long hole (48).
0) also decreases. At the same time, the upper pusher (33) also retreats. That is, it is necessary that the pocket holder (18) be prevented from rotating before the punch mechanism (10) enters the completely lowered state (crimped state B). This prevents damage to fabrics and the like and safety of workers. Also, as the upper pusher (33) retreats, the upper part moves from the chute (31) to the upper pusher guide (32).
). Then punch the part in place (1
6) and the die (35) to tighten the fabric.

FIGS. 10 and 11 are diagrams showing the operation of the rack operating mechanism (26) when the punch mechanism (10) is raised after crimping of the component to the fabric is completed. First, when the parts have been tightened to the fabric, the air cylinder (1
) stops operating and the lever (28) is activated by the tension coil spring (
30) in a clockwise direction in FIG. Then, the first connecting plate (40) moves to the left by a distance (D) within the recess (46) of the second connecting plate (41), as shown in FIG. 10, via the wood (25). At this time, the punch mechanism (10) is also raised by the action of the tension coil spring (13) via the toggle link (9), and the punch mechanism (10)
G) is separated upward from the fabric. Therefore, punch (16
) is in contact with the fabric, the pocket holder (18)
Since it does not rotate, there is no damage to the fabric or any operational hazards. Further, as the first connecting plate (40) moves, the upper pusher (33) also moves, and the upper pusher guide (3
2) Start guiding the upper part inside towards the pocket (19).

Figure 11 shows the case where the rotating rod (3) and lever (28) are rotated clockwise, and are pushed by the second connecting plate (41) or the first connecting plate (40). ,Disc spring(
The pocket holder (18) is moved forward to the left by the rack (23) which is friction-coupled by 43).
is rotated by a predetermined angle. At this time, the punch mechanism (10) is rising, and the upper pusher (33) is also moving forward. When the tip of the rack (23) collides with the stopper (49), the forward movement of the rack (23) is stopped, and the rotation of the pocket holder (18) is also stopped.

From the state shown in FIG. 11, the rotating rod (3) etc. further rotate to return to the initial position as shown in FIG. 6.

Effects of the Invention As described above, according to the present invention, when it is necessary to rotate the upper part by a predetermined angle and attach it to the fabric, the pocket holder is rotated by a predetermined angle by the rack while the punch mechanism is lowering during crimping. When the crimping is finished, the punch mechanism rises and the pocket holder is rotated by the rack after separating from the fabric.Also, when attaching the upper part to the fabric without rotating it, the stopper prevents rotation of the pocket holder with one touch. Therefore, it can be used in cases where there is a need to rotate the upper part in a two-mounted parts mounting machine, or when there is no need to rotate the upper part.

In addition, when rotating the triangular stud or directional upper part set in the pocket to tighten it to the fabric, the part is rotated before the pocket contacts the fabric, which may cause damage to the fabric or parts. This has the advantage that it can be prevented and is also safe for workers.
