Abstract

The invention provides a moving device of a pull head. Only a part is used for locking the pull head and a special drive source is not required, so that the structure is simple and the cost is low. The device comprises a body (10), an arm (2) and a spring, wherein the arm (2) can be supported in a rotary mode relative to the body (1), the spring can push and press the arm (2), the body is provided with a channel (13) through which a long zip of a zip can move, the arm is provided a base (21) which can be supported on the body in a rotary mode, a front end portion (23) which is arranged on the opposite side of the base and a middle portion (22) which is arranged between the base (21) and the front end portion (23), the front end portion is provided with a first projection (24), and the middle portion is provided with a second projection (27). When the arm is pushed and pressed by the spring and moves to a position which is close to the channel, the pull head (4) is hooked by the first projection, when a lower stopper abuts against the second projection, the second projection is pushed upwards by the lower stopper, the arm resists the press of the spring and moves to a position which is far away from the channel, and the first projection is unhooked with the pull head.

Description

Technical field [0001] The present invention relates to a slider moving device, in particular to a slider moving device for moving a slider mounted on a long zipper chain from a position away from the top stop to a position close to the top stop. Background technique [0002] In the manufacturing process of the zipper, the long zipper chain with the zipper element and the slider attached is cut to a predetermined length to obtain Picture 12 Zipper per unit length shown. Then, the quality of the zipper needs to be checked. [0003] The inspection items include, for example, whether there is a top stop, whether the top stop is firmly installed, whether there is a pull tab on the slider, whether the zipper element can pass through the inside of the slider correctly, whether there is a bottom stop, or a bottom stop. Whether the stop is firmly installed, etc. [0004] The inspection can be performed by equipment such as an image inspection unit, but due to the high price, the image insp...
