Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an attachment machine for attaching studs to clothing fabric, and particularly to an attachment machine for attaching directional parts such as triangular studs to be attached to the corner of a pocket opening. It is.

BACKGROUND TECHNOLOGY Normally, a component mounting machine supplies upper parts such as rivets and lower parts such as washers sent from a chute to a caulking punch and a caulking die using a pusher mechanism that reciprocates. The crimping punch and the crimping die are designed to crimp the clothing fabric interposed between the crimping punch 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 11, triangular tacks attached to the opening corners of clothing pockets, or tacks with directional properties on the surface can be used. In the case of buttons with certain characters, symbols, patterns, etc., the rivets or buttons must be crimped and punch-set in a predetermined direction.

Conventionally, as a direction setting mechanism that can determine the direction of a stud or button in this way, the button is rotated in a guide groove while being pushed with a pusher, and the dove formed on the back side of the button head is attached to the latch of the pusher. By locking, the button is oriented in a certain direction and supplied to a positioning head that also serves as a crimping die, and by rotating the positioning column of this head by a certain angle, the button is oriented in a certain direction. A button mounting device for this purpose is disclosed in Japanese Patent Publication No. 11682/1982. The orienting means of this prior art device is such that a pinion is connected 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, the above-mentioned conventional device rotates the lower part set on the crimping die side 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 parts in a predetermined direction. Then, to rotate the upper part on the caulking punch side by a predetermined angle,
The crimping punch side moves up and down, and if the lower end of the punch rotates after contacting the clothing fabric, it may damage the fabric and its parts, and the fabric will also rotate, so the worker should not A problem arises in that there is a risk of danger.

The present invention has been made in view of the above-mentioned problems, and provides direction setting that does not damage clothing, triangular studs that are upper parts, or upper parts that have directionality, and is also safe for workers. The object of the present invention is to provide a parts mounting machine equipped with a device.

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 punch mechanism descends, the upper pusher for setting the component in the pocket of the pocket holder retreats from the lower end of the descending pocket holder, and then the pocket holder is released from the rack. As the pocket holder rotates by a predetermined angle as it moves backward, the punch mechanism comes into contact with the fabric after the rotation of the pocket holder stops, and when the punch mechanism rises, the pocket holder of the punch mechanism is in a position where it is spaced above the fabric. This problem can be solved by providing a parts mounting machine that is characterized by being able to rotate through a predetermined angle.

Function Pocket holder 1 constituting punch mechanism 10
8 is rotated by a predetermined angle by the rack 23 of the rack operating mechanism 26 during the descent of the punch mechanism 10, and after the rotation of the pocket holder 18 has stopped, it comes into contact with the fabric and the part is crimped and attached to the fabric by the punch 16 and die 35. . After attaching the parts, after the punch mechanism 10 is separated above the fabric, the pocket holder 1 is
Since the punch mechanism 10 is raised while the punch mechanism 8 is rotated by a predetermined angle, damage to the fabric etc. and danger to the operator are prevented.

Embodiments Hereinafter, the present invention will be described based on embodiments shown in the drawings.

In FIG. 1, reference numeral 1 denotes an air cylinder, and at the tip of its piston rod 2, a rotating rod 3 is pivotally supported by a frame 5 via a shaft 4. Further, an L-shaped lever 6 is pivotally supported on the shaft 4. One end of the rod 7 is connected to one end of the longer lever of this L-shaped lever 6,
The other end of the rod 7 is connected to a toggle link 9 via a pin 8. A punch mechanism 10 is connected to the other end of one link of the toggle link 9, and when the air cylinder 1 is actuated, the piston rod 2 is raised and the rotating rod 3 is rotated counterclockwise. The provided pin 11 is the L-shaped lever 6
By contacting the impactor 12 provided at
When the punch mechanism 10 opens, the punch mechanism 10 descends. The return, so-called raising, of the punch mechanism 10 is caused by the contraction of the tension coil spring 13 provided on the pin 8 of the toggle link 9 when the operation of the air cylinder 1 is stopped.
will rise.

The punch mechanism 10 is configured to move up and down within a holder 14 attached to the frame 5, and a punch 16 is fixed to the lower end of a ram 15 as shown in FIGS. 2 and 3. , a pocket holder 18 is fitted via a bush 17. At the lower end of the pocket holder 18, pockets 19 for holding triangular studs or a directional upper part are provided and biased by a spring 20 so as to face each other. The pocket holder 18 has a cylindrical shape, and a gear 21 having an angle of at least 90 degrees is formed on the side surface of the pocket holder 18, as shown in FIG. 3, so as to function as a pinion.
A rack 23, which will be described in detail later, has a gear 22 that meshes with this gear 21.
The pocket holder 18 rotates when the pocket holder moves forward and backward, and the position of the upper part can be rotated by 90 degrees. 24 is a stopper when the pocket holder 18 rotates.

The rotating rod 3 is provided with a rack operating mechanism 26 for moving the rack 23 forward and backward 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 lever 28 is rotatably supported on the shaft 4, and a roller 29 that comes into contact with the pin 27 is attached to the lever 28, and is rotated via the pin 27 by the rotation of the rotating rod 3. I'm starting to do that. The lever 28 is normally biased clockwise by a tension coil spring 30. Further, a rod 34 is connected to the lower end of the lever 28 for reciprocating the upper pusher 33 that sets the upper part sent from the chute 31 to the upper pusher guide 32 into the pocket 19. A lever 37 is connected thereto for reciprocating a lower pusher 36 for setting parts.

The rack actuating mechanism 26 includes a first rod 25 connected to the other end of the rod 25, which is connected to the pivot rod 3, as shown in detail in FIGS. 4 and 5.
It is composed of a connecting plate 40, a second connecting plate 41 which is fitted and interlocked with the connecting plate 40, and a rack 23 which is frictionally connected to the second connecting plate 41 with a bolt 42 via a disc spring 43.

As shown in FIG. 5, the first connecting plate 40 has a concave portion 44 and a convex portion 45.
is formed. Further, a convex portion 47 is formed in the second connecting plate 41 by forming a concave portion 46 at a position opposite to the concave portion 44, so that the first connecting plate 40 and the second connecting plate 41 are connected to each other in the concave portion 44, The convex portions 45 and 47 are fitted into the convex portions 46 and are connected to each other.
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 protrusions 45 and 47. Further, the second connecting plate 41 is provided with a long hole 48 at a position opposite to the recess 46 . The second connecting plate 41 is connected to the bolt 42 and the disc spring 43 through this elongated hole 48.
and the rack 23 are connected by clamping pressure, and the second connecting plate 41 can be slid within the elongated hole 48 with a force greater than the frictional force caused by the clamping pressure. Reference numeral 49 denotes a stopper made of a bolt provided on the tip side of the rack 23 to allow fine adjustment. The side plate 50, which constitutes a part of the upper pusher guide 32, is pivotally supported by a pin 51, and if the upper part fed from the chute 31 jams inside the upper pusher guide 32, the side plate 50 It is rotatable so that it can be removed.

Next, the operation according to the present invention will be explained based on FIGS. 5 to 10.

First, when the air cylinder 1 is operated, the piston rod 2 is raised and the rotating rod 3 is rotated counterclockwise. Then, the first connecting plate 40 is moved to the right in FIG. 5 by the play distance D via the rod 25 connected to the rotating rod 3, and the first
Convex portion 45 of connecting plate 40 and convex portion 4 of second connecting plate 41
7 collides. At this time, the upper pusher 33 is also moved to the right by the lever 28, and the tip 33a of the upper pusher 33 retreats from the crimped portion. During this operation, the pin 11 of the rotating rod 3 is in the L position.
Since it is not in contact with the impactor 12 of the lever 6, it is L.
The lever 6 does not rotate and therefore the punch 16 does not descend. That is, before the punch 16 starts its downward movement, the tip 33a of the upper pusher 33 is moved back from the crimping part to ensure safety of the work.

When the rotating rod 3 further rotates from the state shown in FIG. The punching 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 both the protrusions 45 and 47 of the first and second connecting plates 40 and 41 are in contact with each other, the second connecting plate 41 moves as shown in FIG. slide to the right, and rack 23 is in the second position.
Since it is frictionally connected to the connecting plate 41, it moves backward in the right direction in conjunction with the second connecting plate 41. Then, the pocket holder 18 engaged with the rack 23 is rotated by a predetermined angle, that is, 90 degrees, and the upper part set in the pocket 19 is rotated 90 degrees to set it in the correct state. In other words, by not allowing the punch mechanism 10 to descend completely, that is, by rotating the upper part by a predetermined angle during its descent, the inconvenience of damage to the fabric or danger to the operator due to the rotation of the punch mechanism 10 is avoided.

A stopper 24 is located at a position where the pocket holder 18 rotates by a predetermined angle (Fig. 3),
This stopper 24 allows the pocket holder 18 to be
rotation is prevented. FIG. 8 shows a case where the rotating rod 3 is still rotated in this state. That is, by preventing the pocket holder 18 from rotating, the rack 23 is also prevented from retreating. However, as the rotation rod 3 rotates, the second connecting plate 41 moves along the elongated hole 48 against the frictional force of the disc spring 43, and the punch mechanism 10 also descends. At the same time, the upper pusher 33 also retreats. That is, the punch mechanism 1
This is because the rotation of the pocket holder 18 must be prevented before the pocket holder 18 enters the state in which the pocket holder 0 is completely lowered (crimped state). This prevents damage to fabrics and the like and safety of workers. Further, as the upper pusher 33 retreats, the upper part is fed from the chute 31 to the upper pusher guide 32. The parts are then crimped onto the fabric at a predetermined position between the punch 16 and the die 35.

FIGS. 9 and 10 are diagrams showing the operation of the rack actuating mechanism 26 when the punch mechanism 10 is raised after the crimping of the component to the fabric is completed. First, when the crimping of the parts to the fabric is completed, the operation of the air cylinder 1 is stopped and the lever 28 is rotated clockwise in FIG. 1 by the tension coil spring 30. Then, the first connecting plate 40 is connected to the second connecting plate 40 via the rod 25, as shown in FIG.
The connecting plate 41 is moved in the recess 46 by a distance D to the left. At this time, the punch mechanism 10 also has a toggle link 9.
The punch 16 is lifted up by the action of the tension coil spring 13 through the punch 16, and the punch 16 is separated upward from the fabric. Therefore, since the pocket holder 18 does not rotate while the punch 16 is in contact with the fabric, there is no risk of damage to the fabric or operational hazards. Further, as the first connecting plate 40 moves, the upper pusher 33 also moves and begins to guide the upper part within the upper pusher guide 32 toward the pocket 19.

FIG. 10 shows the case where the rotating rod 3 and the lever 28 are further rotated clockwise, and the second
The rack 23 is pushed by the connecting plate 41 or the first connecting plate 40 and is frictionally coupled by a disc spring 43.
As the pocket holder 18 moves forward to the left, the pocket holder 18 rotates 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. 10, the rotating rod 3 and the like further rotate to return to the initial position as shown in FIG. 5.

Effects of the Invention As described above, according to the present invention, during crimping, the pocket holder is rotated by a predetermined angle by the rack while the punch mechanism is lowering, and when crimping is completed, the punch mechanism is raised and separated from the fabric. Since the pocket holder is rotated by a rack, when the triangular stud set in the pocket or the directional upper part is rotated at a predetermined angle and tightened to the fabric, the part can be tightened without the pocket contacting the fabric. This has the advantage of being able to prevent damage to fabrics, parts, etc., and being safe for workers.
