Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide fastener manufacturing apparatus for continuously and automatically finishing a long slide fastener chain.

2. Description of the Related Art As shown in Japanese Utility Model Publication No. Sho 45-12162, for example, a conventional continuous and automatic slide fastener manufacturing apparatus draws a leading fastener chain forward by a second gripper and a stopper next fastener chain. The second gripper is automatically stopped by the limit switch by detecting the foremost end of the dentition of the tooth, and the cutter operates in the vertical direction to cut the fastener chain at a predetermined position.
When the cutting is completed, the cutter opens in the vertical direction, and the first gripper grips the space portion of the fastener chain from both sides. During this time, the second gripper again moves forward to guide the cut front fastener chain out of the machine and drop it downward. Then, in the space in front of the next fastener chain, the parts holder and the supporting caulking rod approach the movement line of the fastener chain, and the slider and the front stopper are held and fixed between them to stand by. Next, while opening the first gripper in a Y-shape, the lower end of the parts holder is passed through and the slider and the front stopper are inserted and mounted, and the front stopper is fixed by caulking. Then, the fastener chain is changed from the first gripper to the second gripper, the tip of the fastener chain is clamped by the second gripper, and when the transfer is started, each operating unit returns to the original position and the fastener chain of the rear fastener chain is returned. Prepare for processing. Thus, there has been known a slide fastener manufacturing apparatus in which cutting of a fastener chain and attachment of a slider and a front stopper are continuously performed automatically.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In a conventional slide fastener manufacturing apparatus, when a slider and a front stopper are attached and a fastener chain is replaced, and a first gripper begins to move backward, the slider is held and fixed. The holder also rises and returns to its original position, and the fastener chain is transferred by the second clipper, so the finished slide fastener is always discharged in the closed state, and a step to activate the slider is required to open it. The second gripper detects the foremost end of the tooth row of the next fastener chain and automatically stops it by the limit switch. It is of a length, and the point that you cannot freely change the length of the slide fastener It was a problem.

Therefore, the present invention is a compact device in which a slider and a stopper can be automatically and continuously attached, and a finishing short slide fastener can be finished in a desired state such as a closed state or an open state, and An object of the present invention is to provide a slide fastener manufacturing apparatus in which the length of the short slide fastener can be freely changed.

In order to solve the problems of the prior art, the present invention, as shown in FIG. 1, has a slide fastener chain F, which is a continuous slide fastener, having a bottom stop T and a slider S attached thereto and having a proper length. In an apparatus for manufacturing a fastener, a gripper device 1 for gripping a tip portion of a slide fastener chain F for finishing and transporting it along a machining line, and a slide fastener chain provided in the transporting direction of the slide fastener chain F so as to be sequentially adjacent to each other. The cutting device 2 for cutting F into a predetermined length, the bottom stopper mounting device 3 for mounting the bottom stopper T, the slider holding device 4 for mounting the slider S, and the timing for releasing the slider S held by the slider holding device 4 are described. A slider holding control device 5 for controlling and a stopper capable of adjusting the stop position of the gripper device 1. It is composed of the device 15.

Next, the cutting device 2 will be described. The cutting device 2 cuts the rear part of the chain F, so that the chain F is fed to the side to which the chain F is fed, and the presence or absence of the chain and the chain of the chain sensing device 21 for preventing the chain from returning. Guide 22
It is provided near the exit of The cutting device 2 is composed of a cutter 23 having a blade at the lower end and a pedestal provided below the chain transfer path, and lowers the cutter 23 from above to cut the chain F.

The lower stopper attachment device 3 is provided in the vicinity of the downstream side of the cutting device 2, and is composed of a forming punch 24, a cutting punch 25, a bender 26, and a die 27 provided below the transfer path of the chain. . The bottom stop sheet metal supplied to the receiving part of the bender 26 is cut into a certain length by a cutting punch 25, and the cut sheet metal is bent by a forming punch 24 to descend, and the ascending lower die 27 Attach the lower stopper T to the chain F in cooperation with. The work of attaching the lower stopper fitting T is performed at the same time as the cutting work when the gripper device 1 first stops.

The slider holding device 4 is provided in the vicinity of the downstream side of the lower stopper mounting device 3 and is located below the transfer path of the chain F, and is held and transferred by the gripper device 1 to the chain F. The slider S is inserted and attached to the tip of the. The slider holding device 4 has a slider holder 28, and a lever for holding the slider S by lowering an elevating rod 30 provided on the slider holder 28.
29 is rotated around the axis pin 31 to move to the position indicated by the chain double-dashed line in FIG. 1, the slider S is supplied to the tip of the slider holder 28 from a slider supply unit (not shown), and the elevating rod 30 is raised to move the lever. 29 is erected, the puller of the slider S is pressed by the clamper 32, and the slider S is held and stands by. Then, at the time of mounting, the slider holder 28 is raised, and the slider S is inserted through the tip of the chain F opened in the Y shape by the gripper device 1 and mounted. A slider sensing device is provided above the slider holder 28.
33 is provided, and the presence or absence of the slider S is sensed by the abutment of the slider S that has risen for mounting. If the slider S is not present, the upper microswitch operates to stop the device. ing.

Finally, the slider holding control device 5 will be described.
The slider holding control device 5 is a device for controlling the timing of releasing the holding of the slider S inserted in the chain F by the slider holding device 4, and is arranged in parallel with the guide bar 6 for guiding the gripper device 1.
