Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a device for automatically attaching a hook and a hook to clothing (for gentlemen and others).

<Conventional technology> A conventional automatic hook driving machine continuously feeds a hook and a seat plate from a hopper through a guide member, and separates the hook and the seat plate between the driving and pressing body and the receiving plate respectively. In the case where the feed mechanism is directly supplied by the feeding mechanism, or just before the hook and the seat plate are supplied between the driving and pressing body and the receiving plate by the respective feeding mechanisms respectively as described above, the supply is temporarily stopped and surely stopped. The mainstream is that one hook hook and one seat plate are supplied, and the supply operation and the driving operation are alternately performed. In any of the above examples, since the seat plate is circular, there is no direction between the hook plate and the hook hook when the seat plate and the hook hook are crimped, so that only the hook hook is hooked to the fabric. It is configured as follows.

<Problems to be Solved by the Invention> However, in the former continuous supply method, the hook and the seat plate are not reliably supplied to a predetermined position, or are repeatedly struck, or the hook and the seat plate are supplied. Since the guide is directly connected to the driving position, there is a drawback that the supply guide is obstructed and repair is difficult.

In the latter example, the guide member is fixed to a predetermined position between the pressurizing body and the receiving plate even if the sheet is not repeatedly struck, since one set is supplied during the guidance. Repair work is difficult as in the former case.

Further, in each of the above examples, the seat plate and the hook hook are provided with their own feed mechanisms, so that the configuration is complicated and the cost is high. On the other hand, when it has a certain direction, it is impossible to caulk both.

In view of the above, the present invention provides a mounting device which can easily cope with an empty hit, an overstrike and other repairs, and can be caulked when the seat plate has directionality with respect to the hook and hook.

<Means for Solving the Problems> A swaging mechanism including a receiving plate holding the seat plate, and an upper pressing body that can be changed in direction by sucking the hook hook and matching the direction of the seat plate. A transfer mechanism for transferring the seat plate and the hook hook to the caulking mechanism to turn the upper pressing body, an intermittent feed mechanism for taking out one seat plate fed from the seat plate dedicated hopper, and a hook hook dedicated The intermittent feeding mechanism takes out one piece while changing the direction of the hook and hook sequentially fed from the hopper.

<Operation> The intermittent feeding mechanism supplies the seat plate fed from the hopper exclusively for the seat plate to the seat plate holding recess of the transfer mechanism, and intermittently feeds the hook hook fed from the hopper dedicated to the hook hook. While changing the direction of the hook and hook by a mechanism, one piece is supplied to the hook and hook holding section of the transfer mechanism. Then, the transfer mechanism held by receiving the seat plate and the hook hook is moved toward the caulking mechanism, the seat plate is held by the receiving plate of the caulking mechanism, and the pressing body is rotated by a predetermined angle on a horizontal plane. At the very least, after the hook hook is sucked and held, the transfer mechanism is retracted, whereby the pressurizing body is reversed by the rotation angle so that the direction of the hook hook matches the direction of the seat plate, and then the caulking mechanism starts the caulking operation. Start.

<Example> Hereinafter, the present invention will be described in detail with reference to examples shown in the drawings. The present invention provides a caulking mechanism A, a transfer mechanism B,
It consists of intermittent feed mechanisms C and D for feeding hook hooks and a seat plate. Of these, as shown in FIG.

Is fixed to the pressing rod 13 of the descending pressing device 11 so as to rotate 90 °, a spring 12 is wound around the pressing rod 13, and one end of the spring 12 is connected to the pressing body 9. And the other end of the spring 12 is anchored on the pressing rod 13 to press the pressing body 9 so as to always rotate clockwise (the direction of the arrow in FIG. 2). Then, by closing an operation switch (not shown), the pressurizing body 9 is lowered, and the hook a held on the lower surface holding portion 10 of the pressurizing body 9 is lowered toward the seat plate b to approach the cloth. It is configured so that both are swaged between them.

Next, as shown in FIG. 2, the transfer device B has a cam surface 4 'formed on the side surface of the distal end, and a through-holding hole 5 for indenting and holding the seat plate b at the center of the upper surface. The moving plate 4 is installed in a direction perpendicular to the line of action of the pressurizing body 9, that is, in a horizontal direction, and the hook and hook holding portions 10 of the pressurizing body 9 and the recesses of the seat plate The receiving plate 2 is advanced toward the space 3 so that the through-holes 5 (see FIG. 1) coincide with the recesses 3 and the movable plate 4 has an upper surface. The holding portion 8 of the hook hook a is fixedly provided at a position directly above the holding hole 5 with a fixed gap between the movable plate 4 and the holding member 8 and is held by the holding member 8. The hook hook a and the seat plate b in the through-hole 5 are made to correspond to each other up and down, and the lower surface of the moving plate 4 is further provided with the bottom of the through-hole 5 as shown in FIG. A follower plate 6 acting as a movable plate is provided at the same height as the receiving plate 2 so as to slide back and forth with the movement of the movable plate 4 as shown by an arrow in the figure, and a front end of the follower plate 6. Is brought into contact with the side surface of the receiving plate 2, and thereafter, only the movable plate 4 is further advanced toward the caulking mechanism A. An arm 15 extending forward from the front end of the holder 8 projects from the upper edge of the push plate 16 attached to the upper surface of the moving plate 4. A roller 14 that rolls in contact with the roller is pivotally mounted.

The arm 15 is connected to the pressing body 9 as apparent from FIG.
When the arm 15 moves forward on the operation line deviated from the center of rotation of the pressurizing member 9 and pushes the protruding portion of the pressing member 9 to one side, the pressing member 9 is rotated by a predetermined angle by 90 °. ing.

Next, the two intermittent feed mechanisms C and D are installed opposite to both sides (see FIGS. 2 and 3) of the moving plate 4 in the transfer mechanism B, and the intermittent feed mechanism C will be described first. A support member 19 of a guide plate 19 'is attached to the front surface of a support angle 18 attached to the right side surface (FIG. 3) of the machine frame 17 with its lower end inclined toward the transfer mechanism B. The inclined lower end is made to correspond to the hook and hook holder 8 of the transfer mechanism B, and a cylindrical body 26 is screwed on the front surface near the end of the support angle 18, and the axis of the hook and hook holder 31 is inserted into the cylindrical body 26. The part 27 is inserted vertically and is freely rotatable, and the holding part 31 is aligned with the inclined upper end of the guide plate 19 ', or the guide plate 19'
A hook hook is supplied from a hook hook dedicated hopper (not shown) via the guide member 34 so as to coincide with a guide member 34 which is inclinedly connected to the cylindrical body 26 in a direction perpendicular to the above. At the lower end of the shaft 27, a crank plate 28 having a pin 29 projecting downward from the lower surface is fixed, and the lower end of the pin 30 projecting from the lower end surface of the cylindrical body 26 is fixed to the upper surface of the crank plate 28. The crank plate 28 is fitted into an arc-shaped recess (not shown) formed to limit the rotation angle of the crank plate 28.

A swing lever 21 is pivotally mounted on a lower surface of a support 20 projecting below the support member 19 of the guide plate 19 ′ by a shaft 22 and one end of a kick spring 23 mounted on the shaft 22 is attached to the swing lever 21. The lever 21 is hooked, and the other end is hooked on the support 20 so that the lever can be constantly turned clockwise (the direction of the arrow in FIG. 4). A roller 24 in contact with a cam surface 4 "provided at the rear portion is pivotally mounted, and a slot 25 is formed at the other end.
The crank plate 28 is rotated by 90 ° by fitting a pin 29 protruding from the lever and swinging the lever 21.

On the transfer mechanism B side of the support 20, a stopper 32 having a roller 32 'pivoted on the upper end is pivotally mounted on a shaft 32 ", and a spring 33 is stretched between the stopper 32 and the support member 19. 5, the stopper 32 is always turned clockwise in FIG. 5, and the roller 32 'is fixed to the hook and hook holder 8 by the pushing piece 7'.
To be in contact with the back surface.

Next, the intermittent feed mechanism D of the seat plate is installed at a position symmetrical to the feed mechanism C with the transfer mechanism B interposed therebetween, as shown in FIG.

That is, a support bracket 36 is mounted on the upper surface of a mounting bracket 35 mounted on the left side surface of the machine frame 17, a guide groove (not shown) for guiding a seat plate is provided on the support bracket 36, and the support bracket 36 is provided. A notch feed lever having a roller 39 pivotally attached to the lower end thereof at the lower end thereof, the roller 39 being in contact with the cam surface 4 'of the moving plate 4;
The lever 38 is pivotally supported by a pin 37, and a spring (not shown) is interposed between the lever 38 and the support portion of the lever 38 so that the lever 38 always rotates counterclockwise with respect to the support portion. The guide member 40 is configured to receive a washer supplied from a hopper (not shown) via a guide groove provided on the support bracket 36.

Next, if you describe the first preparation operation before explaining the series of operations,
First, a large number of hooks a, a,... Are continuously supplied from the dedicated hopper through the guide member 34 in a uniform posture as shown in FIG. Put your feet inside and are held.

In this state, when the transfer mechanism B is advanced once, the cam surface 4 ″ of the moving plate 4 pushes the roller 24 and the lever
The lever 21 is swung counterclockwise with respect to the horizontal plane against the holding elasticity, and the pin 29 at the other end of the lever 21 causes the crank plate 28 and the shaft 27 to rotate 90 ° clockwise with respect to the horizontal plane. As it rotates, the hook hook in the upper holding portion 31 also changes its direction, and passes through the upper notch 26 'of the cylindrical body 26 to the guide plate 19'.
The hook hook slides down along the inclination of the guide plate 19 'and is received by the stopper 32, where it waits for a turn. On the other hand, in the seat plate supplied from the hopper dedicated to the seat plate, a large number of seat plates b, b,... Are waiting for their turn.

Here, it is assumed that the full-scale operation is started. When the start switch of the automatic circuit is pressed, the movable plate 4 moves backward (in the direction of the solid line arrow in FIG. 1) and the cam surface 4 'kicks the roller 39, so that the notch feed lever 38 is turned clockwise. , The topmost one of the row of seat plates is slid down through the guide groove in the support bracket 36 and is put into the through-hole 5 of the movable plate 4.

At the same time, when the roller 32 'is pushed by the pushing piece 7' protruding to the side of the holder 8 and the stopper 32 is rotated counterclockwise in FIG. 5, the foot is received by the stopper 32. The hook hook is released and slides down along the inclination of the guide plate and enters the holder 8.

In this way, the seat plate b is located below and the hook hook a is located immediately above the seat plate b.
When the transfer mechanism B, that is, the moving plate 4 is advanced in this state, the roller 39 is released from the cam surface 4 ', the lever 38 is rotated by the restoring elasticity, and the next seat plate 1 is moved.
Preparations are made to send out the individual.

At the same time, the pushing piece 7 'releases the roller 32' so that the stopper 32 returns to its original function, and when the driven plate 6 is further advanced together with the moving plate 4, the driven plate 6 is eventually moved as shown in FIG. The moving plate 4 abuts on the side surface of the receiving plate 2 and stops, and the moving plate 4 further advances on the receiving plate 2, and the seat plate b in the through-holding hole 5 and the hook hook a in the holder 8. The roller 14 of the arm 15 of the push plate 16 projects forward from the holder 8 at this time.
Before the hooks a and the seat plate b in the through-holding hole 5 intervene between the recess 3 and the holding portion 10, the roller
14 presses the longitudinal piece of the pressurizing body 9 to rotate 90 °,
At the end of the operation, the hook and hook a and the seat plate b are supplied to the corresponding positions of the recess 3 of the receiving plate 2 and the holding portion 10 of the pressing body 9.

At this time, a cam surface 4 ″ formed at the rear of the moving plate 4
Presses the roller 24 to rotate the lever 21 counterclockwise with respect to the horizontal plane as described above, and supplies one hook hook in the holding portion 31 to the primary side of the stopper 32 so as to prepare for the next driving. Works.

Next, when the hook and the seat plate are mounted in their proper positions, the moving plate retreats again and pushes the roller 39 on the cam surface 4 ', and the pushing piece 7' pushes the roller 32 'to repeat the same. Be prepared for operation.

Then, the roller 14 of the arm 15 separates from the side surface of the pressing body 9 at the same time as the retreating operation of the moving plate 4, so that the pressing body 9 is turned by 90 ° clock by the restoring force of the spring 12 as shown by an arrow in FIG. Rotate in the direction. Then, the hook a is modified so that it is in the same direction as the seat b, and in this state, the seat b and the hook a
The pressurizing device 11 is lowered and caulked by interposing a predetermined attachment portion of the clothing between them.

It should be noted that, in the above description, to make the directions of the seat plate and the hook hook coincide with each other, as is clear from the functional schematic diagram of FIG. The seat plate is supplied as it is without changing the direction. However, the hook hook changes its direction by 90 ° when going from the guide member 34 to the guide plate 19 ′ and is sent to the pressing body as it is. By turning, the hook hook
This means that the seat has been rotated by 180 °, so that it can match the direction of the seat plate.

<Effect of the invention> The caulking mechanism of the device of the present invention is such that the hook hook and the seat plate are independently guided between the pressurizing body and the receiving plate by a separate feed mechanism as before. In contrast, a single operation cylinder or the like extrudes and supplies all at once, so the number of parts is reduced and the structure can be simplified, the production cost is significantly reduced, and the inventory of parts is further reduced by reducing the number of parts. It will be easier. Further, the hook hook and the seat plate are not directly supplied between the pressing body and the receiving plate as in the past, but are supplied once after being held on the transfer mechanism. It is easy to manage because it understands the appearance of hooks and hooks well, and it is easy to find troubles such as repeated overstrikes due to failures and driving on only one side, and the most characteristic feature of the present invention is the direction It is possible to assemble the deformable seat plate by matching the directions of the hooks and hooks, and has a special effect such as extremely high versatility, and extremely easy workability and easy repair in case of trouble.
