Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art The present invention is an improvement of the slider forward moving device in the slider pull tab attaching device, which was previously filed by the present applicant (Japanese Patent Application No. Hei 5-231076). Insert the clamper by lowering the slider sandwiched by the holding claws into the opening of the puller connecting part, then cover the opening of the connecting part where the clamper is inserted with the fall prevention piece, open the holding claw to the left and right, and slide the slider. At the same time as releasing the clamp, blow air on the slider from the ejection hole and tilt it forward so that it does not interfere with the tightening work of the next opening, and the connection part of the puller with the slider is conveyed next. It was done.

[0003]

In the above-mentioned slider forward-moving device, air is blown onto the slider and is pushed forward, so that the slider is apt to sway, and therefore the clamper may come out of the opening of the connecting portion. The problem is that there is a limit to the high-speed work because it is sprayed. Therefore, the present invention improves the above-mentioned problems, and the slider can be surely moved forward without the clamper coming out of the opening of the connecting portion, and the slider provided with the slider forwarding device that enables efficient and high-speed production. It is an object of the present invention to provide a puller attaching device.

[0004]

In order to achieve the above object, the present invention has a carrying groove in which the opening of the connecting portion of the puller can be erected and moved upward, and a puller hanging in the carrying groove. A puller that is conveyed from above the clamper of the slider that is sandwiched by the holding claws that reciprocate up and down along the conveyance groove of the puller conveyance device that consists of a conveyance plate that conveys the In the slider puller attaching device, a clamper insertion portion for sequentially inserting the slider into the puller to attach the slider to the puller, and a crimping portion for crimping the connection portion of the puller with the slider clamper inserted therein are provided. , A movable guide plate which is operated by the slider forward tilting cylinder and reciprocates diagonally backward is arranged,
Insert the tape sliding groove of the slider, which is clamped by the holding claws and dropped onto the puller connecting portion, into the movable guide plate, insert the clamper into the puller connecting portion, and then retract the movable guide plate diagonally downward. The slider is moved forward and sent to the next crimping section. In addition, a fixed guide plate is provided along the conveyance groove from the clamper insertion part to the caulking part at a position where it will be connected to the movable guide plate at the position where the slider is tilted forward and retracted, and the tilted slider is moved onto the fixed guide plate. You may make it convey it. Furthermore, a guide that can insert a movable guide plate at a position facing the tape sliding groove of the clamped slider on the holding surface of the holding claw that clamps the slider of the clamper insertion part and inserts the clamper into the puller connection part A groove may be provided.
