DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slider puller mounting device for automatically mounting a puller to a slider for opening and closing a slide fastener, and more particularly to a slider pulling device in a clamper insertion portion.

[0002]

BACKGROUND OF THE INVENTION The present invention is an improvement of a slider pulling device in a slider puller attaching device which was previously filed by the applicant of the present invention (Japanese Patent Application No. 5-231076). Lower the slider sandwiched by the holding claws into the opening of the connecting portion of the puller and insert the clamper, then cover the opening of the connecting portion where the clamper is inserted with the fall-off prevention piece, open the holding claws to the left and right, and At the same time as releasing the pinch, blow air to the slider from the ejection hole and tilt it forward so that it does not interfere with the work of caulking the next opening, so that the connector of the puller with the slider attached is transported next. It was done.

[0003]

In the above-described device for moving the slider forward, air is blown to the slider and the slider is tilted forward, so that the slider easily fluctuates, so that the clamper may come out of the opening of the connecting portion. The problem is that there is a limit to the speed-up work because it is sprayed. Therefore, the present invention improves the above-mentioned problem, and enables a slider to be reliably moved forward without the clamper coming out of the opening of the connecting portion, and a slider provided with a slider forward moving device that enables efficient and high-speed production. The purpose of the present invention is to provide a puller mounting device.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a transport groove which can be hooked and moved upward through an opening of a connecting portion of a puller, and a puller which is hooked on the transport groove. Along the transport groove of the puller transport device consisting of a transport plate intermittently and sequentially transported to each of the processing sections described below, a slider clamper sandwiched by holding claws reciprocating up and down is connected to the puller transported from above A clamp insertion portion for inserting a slider into a handle by inserting the clamper into the portion, and a slider puller mounting device sequentially provided with each processing portion of a caulking portion for caulking a connecting portion of the handle into which the slider clamper is inserted; In addition, a movable guide plate that is operated by the slider forward tilting cylinder and reciprocates obliquely rearward is arranged,
After inserting the tape sliding groove of the slider, which is sandwiched by the holding claws and lowered onto the connecting portion of the handle, into the movable guide plate, and inserting the clamper into the connecting portion of the handle, the movable guide plate is retreated diagonally downward. The slider is moved forward and sent to the next caulking section. In addition, a fixed guide plate is provided along the transport groove from the clamper insertion part to the caulking part at the position where the slider is moved forward and retracted and connected to the movable guide plate, and the slider moved forward is moved onto the fixed guide plate. May be transported. Further, a guide capable of inserting the movable guide plate at a position on the holding surface of the holding claw for holding the slider of the clamper insertion portion and inserting the clamper into the connecting portion of the puller, facing the tape sliding groove of the held slider. A groove may be provided.

An L-shaped movable guide plate 34 is disposed at a position near the connecting portion 5 that is anchored to the movable member 1. This movable guide plate 34
Is a piston 37 attached to a slider forward tilting cylinder 36 provided along the substrate 15 of the puller chute 13.
As shown in FIG. 4, the slider 1 is pulled down diagonally rearward to move the slider 1 forward, and after sending the slider 1 moved forward to the next step, the slider 1 is pushed up diagonally forward to return to the original position. I have. The movable guide plate 34 is positioned when the clamper 3 is inserted. The movable guide plate 34 is provided on the left and right holding surfaces of the holding claws 29 which descend with the slider 1 therebetween, as shown in FIG. 8, a guide groove 31 formed opposite to the tape sliding groove 9 is provided, and when the guide groove 31 is lowered to insert the clamper 3 into the opening 6 above the connecting portion 5, it is movable on the way. The vertical portion 35 of the guide plate 34 is inserted into the guide groove 31 of the holding claw 29 to position the clamper 3, and is further lowered as shown in FIG. 3 so that the clamper 3 is securely inserted into the opening 6 of the connecting portion 5. It is to be inserted. Then, after the clamper 3 is inserted into the connecting portion 5, the holding claws 29 are opened right and left by the holding cylinder 32 to release the slider 1, and then the lifting cylinder 3
3 causes the holding claws 29 to rise and return to the supply position of the next slider 1. As shown in FIG. 3, the slider 1 inserts the clamper 3 into the connecting portion 5 of the pull 4, and
The movable guide plate 34 is released from the holding claws 29 with the vertical portion 35 of the movable guide plate 34 inserted therein, and then the movable guide plate 34 is moved obliquely downward by the piston 36 for moving the slider forward as shown in FIG. Then, the slider 1 is pulled forward with the slider 1 kept as it is, and the upper part of the opening 6 of the connecting part 5 is opened so as not to hinder the caulking operation, and the slider 1 is conveyed to the next step. .

As shown in FIG. 1, the inspection unit 38 has a pull-sensing phototube 39 and a slider-sensing phototube 40 arranged with the transport groove 11 interposed therebetween. Regarding 5, the presence or absence of the slider 1 and the handle 4 is detected and confirmed by the photoelectric tube. The connecting portion 5 into which the clamper 3 has been inserted in the clamper insertion portion 25 is
The slider 1, which has been moved forward, is moved to the fixed guide plate 41, which is connected to the movable guide plate 34 at the front-down position, by the conveyance of the connecting portion 5. The tape is also transferred, and the tape is transported together with the connecting portion 5 while maintaining a fixed posture with the fixed guide plate 41 inserted into the tape sliding groove 9. The fixed guide plate 41 is provided up to the point where the finished product is discharged, and if necessary, is connected to the next device so that the product can be easily delivered. The locking claw 22 for transporting the connecting portion 5 from the clamper insertion portion 25 to the inspection portion 38 and from the inspection portion 38 to the caulking portion 43 is provided with a fall-off prevention cover 42 as shown in FIG. The clamper 3 does not protrude from the opening 6 of the connecting portion 5 inside.

The caulking portion 43 is disposed above the transport plate 21 similarly to the clamper insertion portion 25, and comprises a punch 44 which reciprocates up and down as shown in FIG. 1, and connects the puller 4 into which the clamper 3 is inserted. The opening 6 of the part 5 is being caulked and finished. The connection portion 5 that has completed the inspection is conveyed to a position below the punch 44 by the locking claws 22 of the transport plate 21 while preventing the projections from falling out by the fall-off prevention cover 42, and the locking claws 22 are retracted by the retreat of the transport plate 21. Release, and then the punch 44 descends and the opening 6 of the connecting portion 5 is opened.
Is pressurized and closed to complete the mounting of the handle 4 to the slider 1. Then, as shown in FIG.
The finished product to which is attached is configured to be discharged out of the machine from the end of the transport groove 11 by a locking claw 22 provided at the final end of the transport plate 21.
