Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener chain having a space portion in which a meshing element row is intermittently cut off at a predetermined interval and having a lower stopper at one end of the space portion. The present invention relates to a continuous attachment method of a slider and an upper stop metal fitting and a device for sequentially mounting a slider to an element row from a space portion and subsequently tightening an upper stop metal fitting to the other end of the space portion.

[0002]

2. Description of the Related Art A continuous fastener chain (hereinafter, simply referred to as a chain) in which a space portion lacking an element row is intermittently formed between meshing element rows having a predetermined length is supplied, and the space portion After attaching the lower stopper to one end, the slider is passed through, then the upper stopper is attached, and then the chain is cut into units of product length in a desired process to obtain a slide fastener. Then, attaching the lower stopper, passing the slider,
The bottom stopper is generally attached by a dedicated device. In this way, when each finishing process is independent, especially when the slider threading device and the attachment device for the upper stopper are independent, attach the upper stopper until the slider threading for each finishing lot is completed. It has no choice but to stop it, which is a factor that hinders the improvement of productivity.
In addition, in this case, it is highly likely that the slider will slide on the element row and fall out of the space by the time the upper stopper is attached.

In view of this, a composite finishing apparatus has been proposed, for example, in Japanese Examined Patent Publication No. 63-7761, in which the slider passage and the attachment of the upper stopper are continuously performed on a single apparatus. According to the attachment device for the slider and the upper stopper disclosed in this publication, the chain is stopped when the space portion of the chain that continuously travels with the lower stopper forward is detected, and the left and right tapes are gripped by the gripper. At the same time, open the same space part to the left and right, set the slider held on the slider holder in the expanded space part, then release the grip by the gripper and feed the chain forward, The meshing element array is separated at the front part while passing through the meshing element array from the rear mouth end. The upper stopper holder is inserted into the space part during the chain feeding, the space portion is expanded to the left and right, and the tips of the separated element rows are brought into contact with the upper stopper holder. At this time, the caulking punch is operated and the left and right upper stoppers held by the holder are caulked, and at the same time, the expansion lever inserted adjacent to the chain downstream side of the holder moves the space part to the left and right. Expanded to
At the same time as the upper stopper fitting attached to the chain is separated from the upper stopper holder, the holder is released from the space portion, and then the expanding lever is also detached from the space portion to start the progressive feeding of the chain.

[0004]

However, in the above-mentioned composite finishing device, not only the number of operating members is large,
In particular, since the gripper is moved between the gripping operation and the releasing operation of the chain in the forward direction of the chain and is separated in the left-right direction, a complicated operation is combined, so that the mechanism becomes complicated and high speed is supported. Difficult to do. In addition, since the space portion is opened diagonally to the left and right at the attachment site of the upper stopper, the left and right core cord portions are also opened diagonally to each other, and the upper stopper metal is likely to be attached obliquely to the core cord portion. .

The present invention was developed in order to solve the above problems, and its purpose is to reliably slide a slider with a relatively simple operation and to make the left and right core cords substantially parallel to each other to provide an upper stopper. It is an object of the present invention to provide a method of attaching a slider and an upper stopper, and a device for the same, which can be surely attached in an accurate posture.

[0006]

SUMMARY OF THE INVENTION The above object is to provide a method in which a slider and an upper stopper are sequentially attached to a fastener chain which is continuously supplied and has a space portion intermittently at predetermined intervals between meshing element rows. Then, when the space portion reaches the slider passage portion, the supply of the fastener chain is stopped, a chain split member is inserted into the space portion, and the space portion is expanded to the left and right.
The slider held by the slider holder is transferred and positioned in an expansion space formed between the chain splitting member and the end of the meshing element row, and a fastener chain is supplied for a predetermined distance to provide left and right elements. Introducing the row from the rear mouth end of the slider and pulling it out from the front guide mouth end while separating the element row into right and left, after the element row has been led out a predetermined length from the guide mouth end of the slider Inserting the left and right tape expanding members into the space, and expanding the left and right core cord portions substantially in parallel between the chain expanding member and the left and right tape expanding members, and then separating the separated parts. Achieved by a method of attaching a slider and a top stop fitting of a continuous fastener chain, characterized in that it includes attaching top stop fittings to the left and right ends of the element row, respectively. . Further, according to the method of the present invention, after the slider is transferred and positioned, the core cord pulling means brings the core cord portions of the left and right fastener tapes on the upper stopper metal fitting side closer to each other to ensure the slider passage.

Further, the above object is a device which is arranged in a running path of a fastener chain having a space portion intermittently at a predetermined interval between the meshing element rows, and which sequentially attaches a slider and a top stop fitting to the chain running. A slider supply part installed below the path, a slider holder that moves up and down between the slider supply part and the chain travel path, a predetermined distance in the chain travel direction with respect to the slider holder, and the chain A mounting means for the upper stop fittings arranged above and below the traveling path, and a chain split member disposed between the slider holder and the mounting means for the upper stop fittings and moving up and down inside and outside the chain traveling path; Arranged so as to sandwich the attachment means of the upper stopper with the chain expanding member,
A continuous fastener chain slider and a bottom stopper fitting device having a width substantially equal to that of the chain split member and provided with left and right tape expanding members that move up and down in and out of the chain running path. To be achieved.

According to a preferred embodiment, the slider holder has a slider accommodating portion on its upper surface, and a pin member that is biased and protrudes from a side portion of the slider accommodating portion toward the accommodating portion. A pull tab engaging member is provided below the slider accommodating portion, and a core cord pulling member that allows the left and right core cord portions at the ends of the space portion to approach each other is provided at a portion where the slider is passed through the core cord portion. The space splitting members of the chain splitting member and the left and right tape expanding members are formed of chevron-shaped plate members.

[0009]

First, the chain feeding means is driven to feed the chain. At this time, the lower stopper is already attached to the space portion. Then, after the space portion where the slider is inserted is detected next time during the traveling of the chain, the chain is stopped after a predetermined time has elapsed. At the time of this stop, the substantially central portion of the space portion corresponds to the installation position of the slider holder and the chain split member.

When the chain stops, the chain splitting member moves downward, the lower end is inserted into the space portion, and the space portion expands to the left and right. When the space part is expanded, the slider holder that holds one slider supplied from the slider supply part on the upper surface rises, and the rear opening is directed toward the end of the element row, and then horizontally in the running path of the chain. Positioned and fixed to.

When the slider is set, the core cord moving member is operated in the approaching direction, and the distance between the core cords at one end of the left and right space portions is narrowed. Then, the chain that has been stopped until then is sent for a predetermined distance, the end of the element row adjacent to the core string portion is inserted from the rear opening end of the slider, and it is sequentially separated left and right at the front guide port. To be done. The feed distance of the chain at this time is equal to the distance at which the end portions of the left and right element rows reach the upper stopper fitting position.

When the chain is fed and the end portion of the element row reaches the upper stopper fitting portion, the chain stops and the tape expanding member is inserted into the space portion and the space portion SP.
Expand to the left and right. At this time, the plate width of the tape expanding member is set to be larger than the plate width of the chain splitting member by the size of the element meshing head portion, so that the left and right end faces of the tape expanding member support the left and right core cord portions. The opening width is approximately equal to the expansion width that supports the left and right element rows on the left and right end faces of the chain split member, and between the chain split member and the tape expansion member is the space between the left and right core cord portions and the element row end portions. Will be held almost parallel.

In this way, when the space portion is expanded while maintaining the parallel state by the chain splitting member and the tape expanding member, the attachment means of the upper stop fitting operates to attach the upper stop fitting to the end portion of the element row. . At the time of this attachment, since the left and right space portions and the element row are parallel to each other as described above, the left and right upper stoppers can be surely attached along the core cord portion and the element row.

When the attachment of the upper stopper is completed, all the operating members are retracted from the road surface of the chain to return to the standby position. Then, the chain feeding means (not shown) is driven to start the progressive feeding of the chain. By repeating this operation in sequence, the slider is intermittently passed through the continuous chain at a predetermined interval from the space portion, and the upper stop metal fittings are automatically automatically sequentially attached to the left and right element row ends adjacent to one end of the space portion. It is attached.

The tape expanding member 7 has the same structure as the chain splitting member 5, and the plate width W-2 thereof is the plate width W-1 of the chain splitting member 5.
It is set larger than the element meshing head size. As with the chain splitting member 5, the tape expanding member 7 also moves up and down at a predetermined timing and at a predetermined timing by an operating means such as an air cylinder (not shown) to cooperate with the chain splitting member 5 to create a space. The left and right element rows E adjacent to the ends of the space portion SP are expanded in parallel with the left and right core cord portions of the portion SP. In addition, the operation means of each of the above constituent members in the present embodiment is performed based on an operation command in accordance with an operation procedure from a control device (not shown).

Next, the slider S and the upper stop metal fitting TS for the chain C continuously fed by the apparatus of the illustrated embodiment are shown.
The attachment will be described together with the operation of each component.

FIG. 3 is an explanatory view showing an operation procedure of a method of attaching the upper stop TS, and the stop member forming method of the continuous chain C according to the present invention will be described with reference to FIGS. 1 and 2 mainly.

First, a chain feed means such as a feed roll (not shown) is driven to feed the chain C in the forward direction as shown in FIG. At this time, as described above, the lower stopper BS is already attached to the upstream end of the space SP. Then, a predetermined time elapses after the space portion SP through which the slider is to be inserted next time during the traveling of the chain C is detected by the space portion detecting means (not shown) including a swing lever that turns on and off the limit switch. Chain C stops. At the time of this stop, the substantially central portion of the space portion SP corresponds to the installation position of the slider holder 3 and the chain split member 5.

When the chain C stops, the chain splitting member 5 moves downward, the lower end is inserted into the space portion SP, and the space portion SP expands left and right (upper and lower in FIG. 6). When the space portion SP is expanded, one slider S supplied from the slider supply chute 4 is placed in the upper pocket 31a.
And the slider holder 3 which is held and fixed by the one side wall of the pocket 31a and the pin member 33 ascends.
As shown in FIG. 6, the slider S is horizontally positioned and fixed in the traveling path of the chain C with its guide column S-1 facing the upstream side of the chain. At this time, as described above, the slider pull PM is accommodated in the notch 31b on the chain upstream side surface of the slider holder 3 in a hanging state, and is also engaged so as to project from the upper end of the rotating lever 34 toward the block body 31. The same posture is maintained by being locked by the claw portion 33a.

When the slider holder 3 reaches the above-mentioned position, the core cord part shifting member 2b provided on the second chain guide 2 is actuated in the approaching direction as shown by the arrow in FIG. The interval between the core cord portions BP at one end of the is narrowed as shown in FIG. Subsequently, the chain C that has been stopped until then is fed back a predetermined distance L, and the element row E adjacent to the core string portion BP is opened from the opening end S-2 opening at the downstream end of the slider S. It is fitted and is separated into right and left by the guide pillar S-1 on the upstream side. The reverse feeding distance L of the chain C at this time is the distance at which the end portions of the element row E separated into the right and left reach just above the curling surface 62a of the curling die 62.

The chain C is sent back to the element array E.
When the end portion of the tape reaches just above the curling surface 62a, the chain C stops and the tape expanding member 7 descends, the lower end thereof is inserted into the space portion SP, and the space portion SP of the same portion is moved as shown in FIG. Expand to the left and right. At this time, the plate width W-1 of the tape expanding member 7 is equal to the plate width W of the chain splitting member 5.
-2 is set larger than the size of the element meshing head, so the expansion width for supporting the left and right core cord portions BP on the left and right end surfaces of the tape expansion member 7 is The spread width for supporting the element row E is substantially equal to each other, and the left and right core cord portions BP are held in a substantially parallel state between the chain split member 5 and the tape spread member 7.

When the space portion SP is held in a parallel state and expanded by the chain splitting member 5 and the tape expanding member 7 in this manner, the curling die 62 rises and the left and right element rows adjacent to one end of the space portion SP. The end portion of E is fitted into the guide groove 62b, and one end of the space portion SP is positioned on the left and right curling surfaces 62a. At this time, the upper stopper metal fitting TS is supplied to the punch surface 61a of the caulking punch 61 through a supply chute (not shown), and the punch surface 6
It is held in a pocket portion (not shown) of 1a.

In this state, when the curling die 62 stops at the upper limit position, the caulking punch 61 descends and caulks the upper stopper metal fitting TS to the end of the element row E (see FIG. 9). At the time of this crimping, since the left and right space portions SP and the element row E are parallel to each other as described above, the left and right upper stoppers TS are also reliably attached along the core string portion BP and the element row E.

When the attachment of the upper stopper metal fitting TS is completed, all the above-mentioned operating members are retracted from the chain traveling road surface and returned to the standby position. Then, the chain feeding means (not shown) is driven to start the progressive feeding of the chain C. By repeating this operation in sequence, the slider S is intermittently passed through the continuous chain from the space portion at a predetermined interval, and the upper stoppers TS are automatically attached to the left and right ends of the space portion S sequentially.

In the above embodiment, the lower stopper is attached to the rear end of the space portion of the continuous chain by the lower stopper attaching device in the preceding stage of the apparatus of the present invention. Since the case where it is supplied to the device has been described, the chain sent in the forward direction is once sent backward to mount the slider through and the upper stopper metal. When the lower stopper is attached to the front end of the space portion when it is fed, the chain feed can be performed in the forward direction by arranging the constituent members in the above embodiment in the reverse direction of the chain flow direction. It is possible. Further, the method and apparatus of the present invention can naturally be applied to a fastener chain to which a bottom stopper is not attached.

[0032]

As is apparent from the above description, according to the method and apparatus for mounting the slider through and the upper stop fitting in the continuous chain of the present invention, the slider through and the upper stop fitting can be continuously mounted on a single device. Since it is done, unlike the conventional method where each finish is done on a separate machine, it is not necessary to stop the subsequent equipment in lot units, and when attaching the top stop metal fittings, the left and right core cords and the top stop A simple mechanism between the ends of the element row to which the metal fittings are attached maintains a substantially parallel state, so the left and right upper stop fittings can be reliably attached, and speedup is also supported in combination with the simplification of the mechanism. Therefore, not only can productivity be significantly improved, but also high-quality slide fasteners can be produced.
