ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a slide fastener finishing apparatus which forms a slider and a stop portion in a fastener chain and particularly, the present invention relates to a slide fastener finishing apparatus, in which a pair of right and left element rows as a fastener chain are inserted from a rear opening of a slider with being coupled each other, each of the element rows separated after insertion are coupled again and the stop portion for joining one element coupling end portion to other element coupling end portion is formed.
2. Description of the Related Art
Conventionally, a slide fastener finishing apparatus has been in heavy use in order to obtain a slide fastener finished product by mounting a slider and a stop portion to a fastener chain to be attached to a fly of pants, clothes, a bag or the like.
According to this conventional slide fastener finishing apparatus, for example, with a pull of a slider located on a lower side, the slider is held by a slider holding portion of a support table and respective front end portions of the fastener chain, of which element rows are separated from side to side, are held by fingers, so that these front end portions are inserted from a shoulder of the slider with right and left portions thereof being aligned. Respective element rows after insertion are discharged backward from a rear opening of the slider with being coupled and then, a lower stop implement, which is supplied to a lower stop portion forming portion disposed at a chain downstream side of the slider holding portion, is hammered into a fastener tape by a punch to be attached thereto. For example, an example of this kind of a slide fastener finishing apparatus is described in Japanese Patent Publication No. 51-185 and Japanese Patent Publication No. 59-48085.
Alternatively, for example, Japanese Utility Model Publication No. 6-36737 discloses a slider fit-in apparatus as other slide fastener finishing apparatus for attaching two sliders to a fastener chain with opposing their shoulders or rear openings each other. According to the slider fit-in apparatus disclosed in this publication, an upper plate of one slider is kept in a horizontal state by a slider holding portion disposed at an upper end portion of a slider holding block and the slider is held by gripping a pull hanging downward. In adjacent to the slider holding block, a rotary table, on which a plurality of slider holding portions each having the same constitution are provided in the form of radiation, are arranged rotatably around a horizontal axis, so that the slider is sequentially held at the slider holding portion with rotating this rotary table by gripping a pull of the other slider to be sequentially transmitted from a supply portion. A shoulder or a rear opening of the other slider held at this slider holding portion is positioned with being opposed to the shoulder or the rear opening of one slider by the rotation of the rotary table.
The one slider holds the slider as described above in such a manner that the shoulder or the rear opening of the slider is directed to a chain introduction side by a manual labor to be supplied to the slider holding portion of the slider holding block with the pull of the slider is hanging. The other slider is held at the slider holding portion of the rotary table and rotated, and then the slider stops toward the chain introduction side under the condition that the shoulder or the rear opening of the slider is opposed to the shoulder or the rear opening of the one slider.
After the other slider is supplied, when the rotation of the rotary table stops, the fastener chain is transmitted to a fastener chain insertion position of the slider and the fastener chain is inserted from the shoulder or the rear opening of the pair of sliders held along a transfer path of the fastener chain.
Further, Japanese Patent No. 2631048 discloses one example of other slide fastener finishing apparatus. The slide fastener finishing apparatus disclosed in this publication comprises a lower stop implement attaching device for attaching a lower stop implement disposed at the chain upstream side along the transfer path of the fastener chain and a slider holding device for attaching the slider disposed rotatably at the chain downstream side of the lower stop implement attaching device around the horizontal axis. The fastener chain is transmitted from the chain upstream side to the downstream side across the lower stop implement attaching device and the slider holding device by a gripper device.
In order to finish the slide fastener with using this conventional slide fastener finishing apparatus, it is necessary for the slider to be supplied to a slider supplying position located above the slider holding device with hanging the pull and directing the shoulder of the slider toward the chain introduction side. In the supplied slider, the pull of the slider is held at the slider holding device and then, the slider holding device is rotated by 180 degrees downward, so that the pull of the slider is held at a front side to make the slider stand at a slider insertion position.
A pair of right and left element rows of a fastener chain is gripped by the gripper device with being coupled, transmitted along the transfer path of the fastener chain and inserted from the rear opening of the slider, so that the slider is mounted to the fastener chain. After that, under the condition that the element rows are coupled, the lower stop implements are attached for each required length of the fastener chain from the upper plate side of the slider by the lower stop implement attaching device disposed on the chain upstream side of the slider holding device and then, the fastener chain is cut.
Alternatively, as other slide fastener finishing apparatus, for example, Japanese Patent Publication No.
59-51819
discloses the lower stop implement attaching apparatus, which forms a space in the continuous element rows as well as hammers the lower stop implement into a fastener tape at the end portion of this space by shearing and cutting a portion of a head in the element rows of the fastener chain to be transferred with the pair of right and left element rows engaged each other.
Further, Japanese Patent Publication No.
6-71446
discloses a slide fastener manufacturing apparatus for attaching a lower stop implement by a lower stop implement attaching device disposed at an upstream side of a chain of a slider holding device in such a manner that a front end of a fastener chain with the element rows being closed is gripped by a gripper device, the fastener chain is inserted from a rear opening of a slider held by the slider holding device with the pull being located on the underside thereof and the element rows are separated.
Generally, in the case of obtaining a slide fastener finished product by attaching a single slider and a stop implement to a fastener chain, for example a pair of separated upper stop implements is formed at one end of the fastener chain in advance and then, other end portion of the fastener chain is inserted from a shoulder of the slider under the condition that the right and left element rows of the fastener chain are separated. After respective inserted element rows are transmitted backward from the rear opening of the slider with being engaged with each other, the lower stop implement for connecting element coupling end portions is formed in the fastener chain.
By the way, for example, in a traveling bag opened and closed by a slide fastener, there is a case that a single slider is inserted in a fastener chain and the stop implements for connecting element coupling end portions are formed respectively at the opposite ends of this chain.
In order to finish the slide fastener to be used for the opening portion of such a traveling bag or the like, at first, a stop implement for connecting the element coupling end portions is formed at a portion inlying by a certain length from one end of the fastener chain whose element rows being coupled wit
