The present invention relates to a device for automatically attaching slider parts such as pull tabs, locking rakes, springs and covers to a slider body in an automatic assembly device that sequentially assembles a slider for a slide fastener.

The turntable, which holds several slider bodies at circumferentially equal intervals, rotates intermittently through a series of work stations or units arranged around it, pulling tabs, locking rakes, springs and covers sequentially. An automatic slider assembly apparatus of the type which automatically attaches various slider components such as the slide fastener sliders in order is proposed. Upon attachment, each slider component is transferred straight from the chute onto each slider body on the turntable, and then attached to the slider body by clinching or pressing.

In such a structure, each work station or unit requires two separate devices, namely a component supply device and a component attachment device, so that the slider assembly is bulky and structurally complex. Since the slider parts to be attached are rather small and light, it is difficult to accurately set such parts at a desired position on the slider body when carrying the parts straight from the chute to the slider body as in the prior art. This difficulty is even more pronounced when the slider part is elastic, because such slider parts are likely to deviate from their desired position on the slider body after being transported by their elasticity.

Therefore, the object of this design is simple and compact in structure, and it is possible to receive the slider parts stably from the chute, and to attach the slider parts accurately to the desired position on the slider body, and the slider parts which can be provided in the slider assembly extremely easily. To provide an attachment.

The apparatus for attaching the slider component to the slider body in a device for assembling a slide fastener slider, provided in accordance with this design, includes a swingable support block and an elongated attachment rod slidably mounted to the support block. At one end of the applicator rod there is an actuating part which can be located between a first position receiving the supplied slider part and a second position attaching this slider part to the slider body according to the swinging motion of the support block, the support block being a spring means. Is pushed in the direction in which the operating portion is placed in the first position. A linear motion plate cam is hooked to this support block to push the support block against the spring means to move the actuation to the second position. The actuating block is connected to the plate cam and can be caught on the other end of the applicator rod, pushing the applicator rod in the direction of attaching the slider component to the slider body while the work piece is held in the second position. The drive means is operatively connected to the cam plate to reciprocate the cam plate.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The principles of this design are particularly useful when implemented in the attachment 10 for attaching the locking rake to the slider body where the pull tab is pre-assembled.

The attacher 10 has a generally rectangular support block 11 rotatably mounted by a shaft 12 on a base or turntable 14 which can rotate intermittently, so as to slide on the support block 11. It is installed and extends in the longitudinal direction through the support block 11 is composed of an elongated attachment rod 15, both ends protruding from the support block (11). One end of the attachment rod 15 has an actuating part 16 and the other end has a cam commodity in the form of a roller 17, and the roller 17 has a linear motion plate cam installed to slide on the frame 13. It is retained so that it may contact with the cam surface 18a of 18. The support block 11 also comprises a cam follower in the form of a roller 19 which is held in rolling contact with the cam face 18a of the plate cam 18. The plate cam 18 can reciprocate to oscillate the support block 11 about the shaft 12 such that the activator 16 moves back and forth toward the outlet 20a of the component supply chute 20. You can do it.

The actuator block 21 is fixed to the rear end of the plate cam 18 and is caught by a roller 17 on the applicator rod 15 so that the applicator rod 15 can be pushed forward. The actuator block 21 is connected to the piston rod 22a of the hydraulic cylinder 22, so that when the cylinder 22 is operated, the actuator block 21 and the plate cam 18 connected thereto reciprocate to support the block. (11) and the attachment rod 15 supported by this are rocked. A tension spring 23 extends between the lever 24 and the frame 13 integrally connected to the support block 11 via the shaft 12 to push the support block 11 clockwise in FIG. Although the swing momentum of the support block 11 is essentially determined by the cam face 18a shape of the plate cam 18, the stop bolt 25 for limiting the clockwise rotational movement of the support block 11 is provided with a frame 13 It is screwed through the bracket 26 fixed to the).

The stop bolt 25 is fixed in place so that it can be adjusted by a nut 27 tightened thereon, and one end of the stop bolt is in contact with one side wall of the support block 11 at a normal time to move the operating part 16. It serves to hold in the position close to the outlet 20a of the chute 20. The protruding length of the stop bolt 25 extending between the bracket 26 and the support block 11 can be adjusted by the nut 27 so that the position of the actuating portion 16 can be accurately positioned relative to the spout outlet 20a. Adjusted.

When the cylinder 22 is operated to extend the piston rod 22a, the actuator block 21 and the plate cam 18 are advanced so that the raised portion of the cam surface 18a is caught by the cam follower 19. When caught in this way, the support block 11 is turned by the plate cam 18 in the half-direction of FIG. 1 against the force of the tension spring 23 about the milia shaft 12, and thus the operating portion 16. Is formed on the outer circumferential wall of the turntable 14 at equal circumferential intervals and descends toward the plurality of recesses 28 which receive the slider bodies. This counterclockwise rotational momentum of the support block 11 is limited by the stop bolt 29 screwed through the bracket 26 alongside the stop bolt 25, which stop bolt 29 is thereon. It is fixed in place to be adjusted by the tightened nut 30. One end of the stop bolt 29 usually faces the side wall of the support block 11. Since the protruding length of the stop bolt 29 extending between the bracket 26 and the support block 11 can be adjusted by the nut 30, the position of the actuating portion 16 is the groove portion 28 of the turntable 14. Is precisely adjusted for.

When the piston rod 22a of the cylinder 22 is further extended, the actuator block 21 is engaged with the roller 17 as shown in FIG. 2, pushing the attacher rod 15 forward. The forward movement of the piston rod 22a is limited by the stop bolt 31 screwed through the bracket 32 fixed to the plate cam 18. The maintenance bolt 31 is fixed in a fixed position so as to be adjustable by a nut 33 tightened thereon, and one end of the stop bolt 31 is usually facing the end surface of the frame 13. The protruding length of the stop bolt 31 which extends between the bracket 32 and the frame 13 can be adjusted by the nut 33 so that the actuating part 16 moves to the fifth position when the piston rod 22a is fully extended. Take the position of the island. When the piston rod 22a is retracted, the attachment rod 15 is moved backward by the force of a pair of compression springs 34, which act between the attachment rod 15 and the support block 11 to act.

As shown in FIG. 2, the actuating portion 16 of the applicator rod 15 has a lower guide member 35, a first push pad 36 slidably positioned on the guide member 35, and a first press. And a second push pad 37 that is slidably positioned on the pad 36. The pressing pads 36 and 37 are usually backed off from the front end of the guide member 35. The actuator 16 is also elastically connected to the guide member 35 to form a pair of side plates 38 together with the guide member 35 and the push pads 36, 37 to form a pocket 39. (Only one is shown), and the pocket 39 houses the locking rake 40 to be attached to the slider body 41 (FIG. 5). The side plates 38 are normally forced to retract one another. Retain the locking rake to the end and end of the pocket 39 so as not to fall off the operating portion (16).

The guide member 35, the first and second push pads 36, 37 and the side plate 38 are all burnt to the body of the attacher rod 15 by compression springs (not shown) acting therebetween. Since they are sexually connected, they can move with the applicator rod 15 if there is no load on the compression springs, and can move independently of one another if the compression springs are deformed by the force applied to the respective members 35-38. . The upper guide plate 20b of the chute 20 carries each locking rake 40 in the pocket 39 stably, but the operating part 16 when the operating part angularly moves back and forth from the chute 20. It protrudes from the exit 20a so as not to get caught.

Before explaining the operation of the attacher 10, the umbrella slider body 41 and the locking rake 40 to be assembled thereon will be described with reference to FIGS. 3A and 3D. The slider body 41 includes a pair of substantially inverted U-shaped lugs 42 disposed on the upper blade 43 and spaced side by side. At one end of the approximately rectangular pull tab 44, the pivot 45 is received so as to rotate in the lugs 42, and two holes 46a, 46b are provided near both ends of the pull tab 44. Is formed. One end of the locking rake 40 formed by bending the elastic sheet metal strip into an approximately ε shape is connected to the retaining portion 47, the other end is the locking portion 48, and the portion extending from the locking portion 48 is approximately inverted U-shaped. The pressing part 49 is used. As shown in Figure 3 (b), the locking rake 40 is assembled with the slider body 41 from the upper side of the upper blade 43, wherein the pull tab 41 is laid flat on the upper blade 43 Retained in reclining position.

In the assembling operation, the retaining portion 47 is pressed into the vertical hole 50 formed at the front end of the slider body 41, and then the pair of lateral shoulders 47a protrudes into the hole 50. The locking projection 51 is caught on the third (c) as well. When the locking rake 40 is assembled on the slider body 41 in this way, the pressing portion 49 abuts against the pivot 45 of the pull cap 44 by the elasticity of the locking rake 40, and the locking portion 48. Protrudes through the hole 52 of the upper blade 43 into the approximately Y-shaped guide channel 53 in the slider body 41. When the pull tab 44 rotates from the lying position of FIG. 3 (b) to the inclined position of FIG. 3 (d), the cam 54 on the pivot 45 is locked by the pressing plate 49 of the locking rake 40. The part 48 is withdrawn from the guide channel 53 into the hole 52.

The component attacher 10 operates as follows: For purposes of illustration, the operation begins with the components of the attacher 10 in the state of FIG. In this state, the piston rod 22a of the cylinder 22 is fully retracted to hold the plate cam 18 in the retracted position. Since the support block 11 is coupled to the stop bolt 25, the rotation of the shaft 12 is prevented by the force of the tension spring 23. In this coupled state, the actuator 16 is located close to the outlet 20a of the chute 20. The turntable 14 is held such that at least one recess 28 is retained facing the component attacher 10, and the lock rake carried from the chute 20 into the pocket 39 of the actuator 16 40, one is elastically retained in the pocket 39 (FIG. 2).

When the cylinder 22 is operated to extend its piston rod 22a, the actuator block 21 and the flake cam 18 are advanced. When the plate cam 18 moves forward, the raised part of the cam surface 18a is bitten by the cam follower 19, and the support block 11 is centered on the shaft 12 against the force of the tension spring 23. It rotates clockwise to abut the stop bolt 29 (FIGS. 1-4). When the support block 11 is caught by the stop bolt 29, the operating portion 16 is located close to the groove 28, facing the slider body 41, wherein the slider body 41 is pull tab 44 ) Is held in the recess 28 while lying flat on the upper blade 43 of the slider body 41.

When the piston rod 22a is further extended, the actuator block 21 is engaged with the roller 17 and pushes the roller 17 forward. Thus, when the attachment rod 15 is advanced toward the slider body 41, the locking rake 40 is moved onto the slider body 41 until the locking rake 40 and the slider body 41 are assembled together as shown in FIG. Will be pressed.

A series of attaching parts is described in detail below with reference to FIGS. 3 (c) to 5. When the applicator rod 15 moves forward, all the parts 35-38 in the actuator 16 move towards the slider body 41. The side plate 38 is engaged with the lugs 42 of the slider body 41 and the guide member 32 protrudes through the hole 46a of the pull tab 44 to form the lower edge of the hole 52 (first). When combined with the upper blade 43 of the slider body 41 adjacent to (5 degrees), the operating portion 16 is stopped. At this time, the locking rake 40 is supported on the guide member 35. As the applicator rod 15 continues to advance, the first and second push pads 36 and 37 move forward to press the locking rake 40 onto the slider body 41.

The pressing portion 49 of the locking rake 40 is the pivot 45 of the pull tab 44 while the locking portion 48 protrudes through the guide channel 53 of the slider body 41 through the hole 52. When combined with the first movement of the push pad 36 is finished. Then, the second push pad 37 is further advanced until the transverse shoulders 47a are caught on the locking projection 51 to move the retaining portion 47 of the locking rake 40 to the slider body 41. Push in the hole (50). Immediately thereafter, the stop bolt 31 engages with the frame 13 to stop the forward movement of the piston rod 22a. Then, when the cylinder is operated to retract the piston rod 22a, the attachment block 21 and the plate cam 18 move backwards, and the attachment rod 15 and the support block 11 are compressed springs, respectively. Forces 34 and tension springs 23 return to the initial positions of FIG.

Thereafter, in order to prepare the attacher 10 for attaching the next locking rake 40, the turntable 14 is angularly moved by an angle corresponding to the distance between the adjacent recesses 28 so that the next recess 28 is provided. Position the slider body 41 held in the). The front slider body 41 to which the locking rake 40 is attached is carried to the next processing station. The component attacher 10 then repeats the operation cycle described above.

An example of a slide fastener assembling apparatus is shown in FIG. 6, wherein the component attacher 10 is provided with one of the continuous work units arranged circumferentially around the turntable 14. In accordance with the intermittent rotational movement of the turntable 14, the slider body 41 is supplied one by one to the groove 28 by the slider body supply unit 55, and then the pull tab 44 is pulled tab attaching machine. (56) is applied to the slider body (41), and then the locking rake (40) is applied to the slider body (41) by the component attacher (10) of this invention, and finally the slider assembled is the discharge unit ( Discharged at 61). Inspection devices 58, 59 and 60 are identified between adjacent processing units 55, 56, 10 and 57 which identify good sliders in the volume sliders. The inspection units 58, 59, 60 are electrically connected to the discharge unit 57 and the other discharge unit 61, so that the two discharge units which separately discharge the good slider and the bad slider ( 57), 61 controls the operation.

As described above, according to the pivoting motion of the support block 11, the actuating portion 16 of the attachment rod 15 has a first position for receiving the slider component, that is, the locking rake 40 from the chute 20; A single pendulum motion is made between the second positions proximate the slider body 41 held on the turntable 14. In the second position, the actuating portion 16 makes a movement to push the locking rake 40 to the slider body 41 in response to a linear reciprocation of the attachment rod 15. This structure makes it possible to accurately attach the slider part to the slider body even if the slider part is relatively small, light and sometimes elastic.

The above-mentioned rocking motion of the support block 11 and the linear reciprocating motion of the actuator 15 also take place via the plate cam 18 and the actuator block 21 connected to the drive means by a single drive means 22.

The component attacher 10 configured in this way is simple and compact in structure, so that the attacher can be installed in the automatic slider assembly extremely easily.
