Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a device for automatically attaching hooks and hooks to clothing (men's and other).

Conventional technology> In the conventional automatic hook-driving car, the hook and the seat plate are continuously fed out from the hopper through the loading plate, and the hook and seat plate are placed between the driving pressurizing body and the receiving plate. In some cases, the hook and the seat plate are directly fed by separate feeding mechanisms, and similarly to the above, the hook and the seat plate are fed by separate feeding mechanisms, and the hook and seat plate are fed once just before being fed to the opening between the pressing body and the receiving plate. The mainstream method is to stop the supply and reliably feed the seat plates one by one in the same manner as a hook and hook, and to alternately perform the feeding operation and the driving operation. In both of the above examples, since the seat plate is circular, there is no directionality in the opening of the hook when crimping the seat plate and the hook hook, so only the direction of hooking the hook to the fabric is determined for the hook hook. As shown in the ellipse 1.

<Problems to be solved by the invention> However, in the former continuous feeding method of the above-mentioned conventional examples, the hooks and seat plates may not be reliably fed to the predetermined positions, may be overlapping, and the hooks and seat plates may not be fed properly. Since the guide directly leads to the driving position, there is a drawback that the supply guide gets in the way and is difficult to repair.

In addition, in the latter example, since the guide member is supplied to one set during the guidance, even if the guide member is not repeatedly struck, the guide member is placed toward a predetermined position between the pressurizing body and the receiving plate. As in the former case, the supplementary work (T1) is difficult.

In addition, in each of the above examples, the seat plate and the hook hook have a unique feeding mechanism, which results in a complicated structure and high cost.In addition, in the above conventional examples, the seat plate is not circular in shape, but the hook hook has a specific shape. On the other hand, if the material has a certain directionality, it is impossible to caulk the two together.

Accordingly, the present invention provides a mounting device that can be easily used for repairs such as dry firing and overlapping, and can also be caulked when the seat plate has directionality with respect to the hook.

Means for Solving the Problems〉 A crimping mechanism consisting of a receiving plate that holds the seat plate and an upper pressurizing body that attracts the hook and allows the direction to be changed in accordance with the direction of the seat plate. , a transfer mechanism that transfers the seat plate and the hook hook to the converting mechanism and turns the upper pressurizing body; an intermittent feeding mechanism that takes out the seat plate one by one fed from a hopper dedicated to the seat plate; and a hook hook. This method consists of an intermittent feed lflblm in which the hooks are sequentially fed from a hook-dedicated hopper and are taken out one by one while changing the direction of the hooks.

Intermittent feeding of the seat plate fed from the hopper exclusively for seat plates 1) The R structure feeds the seat plate one by one to the seat plate holding recess of the transfer mechanism, and the hook hook fed from the hopper exclusively for hook hooks. While changing the direction of the hook hook by intermittent feeding 8% mechanism, 1
The pieces are supplied to the hook holding section of the transfer machine.

Then, the transfer mechanism that receives and holds the seat plate and the hook is moved toward the caulking mechanism, and the seat plate is held by the receiving plate of the caulking mechanism, and the pressurizing body is rotated by a predetermined angle on the horizontal plane. After at least suctioning and holding the hook, the transfer mechanism is withdrawn, so that the pressurizing body is reversed by the rotation angle to align the direction of the hook with the direction of the seat plate, and then the crimping mechanism performs a calving operation. Start.

The roller 14 to be transferred is pivotally mounted.

As shown in FIG. 2, the arm 15 is connected to the pressurizing body 9
When the arm 15 moves forward, a portion of the pressurizing body 9 protruding toward one side is pushed to rotate the pressurizing body 9 by a predetermined angle of 90°. ing.

Next, the two intermittent feeding mechanisms C and D are installed opposite to each other at the back of both sides of the moving plate 4 (see FIGS. 2 and 3) in the transfer mechanism B. Of these, the intermittent feeding mechanism VT will be described first. , the support member 19 of the side plate 19 is attached to the front of the support angle 18 attached to the left side of the machine frame 17 (Fig. 3).
is installed with its lower end inclined in the direction of the transfer mechanism B, and the inclined downward end of the guide plate 19° corresponds to the hook holder 8 of the transfer mechanism B. The body 26 is screwed on, and the detail 27 of the hook hook holder 31 is vertically inserted into the cylindrical body 26 so that it can rotate freely, and the holder 3] is aligned with the inclined upper end of the guide plate 19. or the cylindrical body 2 in a direction perpendicular to the guide plate 19.
A hook hook is supplied from a hopper (not shown) exclusively for hook hooks through the 141 member 34 so as to match the id member 34 connected at an angle to the hook hook. A crank plate 28 having a pin 29 projecting downward from the lower surface is fixed to the lower end of the shaft portion 27, and a pin 3 projecting from the lower end surface of the cylindrical body 26.
0 to the upper surface of the crank plate 28.
It is fitted into an arcuate recess (not shown) provided in order to limit the rotation angle of the shaft.

The swing lever 2 is attached to the lower surface of the support member 20 protruding from the lower side of the support member 19 of the guide plate 19' by means of M22.
A kink spring 2 is mounted on the pongee 22 at the same time as the pongee 22.
One end of the lever 3 is hooked to the lever 21, and the other end is hooked to the support 20 so that the lever is always pivoted clockwise (in the direction of the arrow in FIG. 4). is a roller 2 in contact with a cam surface 4'' provided at the rear of the movable plate 4;
4 is pivotally mounted, and a long hole 25 is formed at the other end, and by fitting the long hole 25 with a pin 29 protruding from the crank plate 28 and swinging the lever 21, the crank plate 28
is rotated 90'.

Further, a stopper 32 having a roller 32" pivotally attached to the upper end thereof is pivotally mounted on the transfer mechanism B side of the support body 20 with a pongee 32", and a spring 33 is tensioned between the lever 32 and the support member 19. so that the lever 32 is always faced and rotated clockwise (FIG. 5), and the roller 32' is connected to the hook hook holder 8.
It is provided so as to come into contact with the back surface of the pushing piece 7' set at .

Next, the seat plate intermittent feed fivtD is installed at a position symmetrical to the above-mentioned feed mechanism C with the transfer mechanism B in between.

That is, a support metal fitting 36 is attached to the upper surface of a mounting metal fitting 35 attached to the left side of the machine frame 17, and an id groove (not shown) for guiding the seat plate is provided on the support metal fitting 36. A notching feed lever 38, which has a roller 39 pivotally attached to its lower end that comes into contact with the cam surface 4' of the movable plate 4, is pivotally supported near the rear upper part of the metal fitting 36 by a pin 37, and the lever 38 is attached to a support portion. The lever 38 is rotated counterclockwise at all times.
A spring (not shown) is interposed between the lever 38 and the support tH3, and a washer supplied from a hopper (not shown) via the idle member 40 is installed on the support fitting 36. In the sutra, uke is configured to receive.

Next, before explaining the series of operations, the first preparatory operation will be described. First, a large number of hook hooks are continuously supplied from a special hopper through the id member 34 in the same posture as shown in Fig. 3. One of the most advanced hooks is held with its foot part inserted into the groove 31' of the holding part 31.

When the transfer mechanism B is moved forward in the second state, the cam surface 4'' of the moving plate 4 pushes the roller 24, causing the lever 21 to swing counterclockwise against the holding elastic force. The pin 29 at the ft!! end of the lever 21 rotates the crank plate 28 and the detail 27 by 90° clockwise, changing the direction of the hook in the holding part 31 at the upper end, and changing the direction of the hook in the upper end notch 26 of the cylindrical body 26. After passing through the guide plate 19, only one hook is sent to the guide plate 19, and the hook slides down along the slope of the guide plate 19, and the catch is stopped by the stopper 32, where it waits for its turn. A large number of seat plates, b, . Waiting for their turn.

At this point, full-fledged operation will begin, and when the start switch of the automatic circuit is pressed, the movable plate 4 will move backward (in the direction of the solid arrow in Figure 1), and the cam surface 4' will kick the roller 39, so that the notch feed lever 38 will move clockwise. The most advanced one of the rows of seat plates slides down through the id groove in the support metal fitting 36, and the seat plate is inserted into the through-holding hole 5 of the movable plate 4.

At the same time, when the pusher piece 7 protruding from the side of the holding device 8 pushes the roller 32 and rotates the stopper 32 counterclockwise, the hook whose foot was stopped by the stopper 32 is released. is released and slides down along the inclination of the guide plate and enters the holding member 8.

In this way, the seat plate b is held at the bottom and the hook a is held just above it.In this state, when the transfer mechanism B, that is, the moving plate 4 is advanced, the roller 39 is released from the cam surface 4'. The lever 38 rotates due to the restoring elasticity, and the next seat plate 1
Preparations are made to send out the pieces.

At the same time, the pushing piece 7' releases the roller 32', so the stopper 31 returns to its original function, and when the driven plate 6 is further advanced together with the movable plate 4, the driven plate 6 eventually touches the side of the receiving plate 2. The movement of the moving plate 4 is blocked and stopped due to contact with the movable plate 4.
moves further forward on the receiving plate 2 and holds and transfers the seat plate in the penetrating holding hole 5 and the hook a in the holding JA-8, respectively. At this time, the arm 15 of the pushing plate 16 roller 14
8 protrudes forward from the holding part 8, so each hook a in the holding hole 5 passing through the holding tool 81 and the seat plate are temporally preceded by the time they intervene between the recess 3 and the holding part 10. The roller 14 presses the arm of the pressurizing body 9 and rotates it by 90 degrees, so that when the operation is completed, the hook a and the seat plate 2 are connected to the recess 3 of the receiving plate 2 and the pressurizing body 9. It will be supplied to the corresponding position of the holding section 10.

At this time, a cam surface 4'' formed at the rear of the moving plate 4 is
presses the roller 24, rotates the lever 21 counterclockwise as described above, and operates to supply one hook in the holding portion 31 to the primary side of the stopper 32 in preparation for the next driving.

Next, when the hook and the seat plate are installed in the correct position, the movable plate moves back again and the cam surface 4゛ pushes the roller 39, and the pushing piece 7゛ pushes the roller 32゛ and repeats the same process. Ready for action.

Then, the roller 14 of the 7-m 15 separates from the side surface of the pressure body 9 at the same time as the movable plate 4 moves backward, so the pressure body 9
It rotates 90 degrees clockwise due to the restoring force of the hinge 12. Then, the hook hook a is corrected so that it is in the same direction as the seat plate, and when the seat plate is placed in this state, a predetermined attachment part of the clothing is interposed between the hook hook line and the pressure device 5!11 is lowered. It is something that is caulked.

Furthermore, in order to match the direction of the seat plate and the hook in the above, as is clear from the functional diagram of FIG. Moreover, the seat plate is fed as is without changing its direction, but the hook changes its direction by 90 degrees when going from the γ-id member 34 to the id plate 19, and is sent as it is to the pressurizing body, so the rear part thereof is pressurized. By rotating the body 90 degrees, the hook has been rotated 180 degrees, and can be aligned with the direction of the seat plate.

<Effects of the Invention> The crimping mechanism of the device of the present invention is different from the conventional one in that the hook and seat plate are independently guided between the pressurizing body and the receiving plate by separate feeding mechanisms. Unlike conventional methods, the system uses a single operation cylinder to extrude and supply the parts all at once, which reduces the number of parts and simplifies the configuration. This significantly reduces manufacturing costs and reduces parts inventory. Management becomes easier. Furthermore, instead of directly feeding the hook and seat plate between the pressurizing body and the receiving plate as in the past, they are first held on the transfer WIItR and then fed. Therefore, the state of the seat board and hook hook can be clearly seen, making management even easier. Trouble such as overlapping due to a malfunction or driving only on one side can be quickly detected, and is the most distinctive feature of the present invention. The advantage is that it can be assembled by matching the direction of the hook to the directional deformed seat plate, making it extremely versatile, and has unique advantages such as extremely easy workability and repair in the event of trouble. has.
