Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a jig setting device for fixing a set to be sewn. For example, the present invention relates to a jig setting device suitable for use in manufacturing a pad insert (constructed by stitching a resin frame and a half net) of a bag built-in pad in a steering wheel of an automobile.

<Prior Art> Usually, an automatic sewing machine M as shown in FIG. 5 is used to sew the resin frame 1 and the half net 3 in manufacturing the insert as described above.

These automatic sewing machines M are provided with a jig 7 for fixing the set 5 to be sewn.
And a pressing member 11 for pressing the set 5 to be sewn, and an automatic feeding means 13 for automatically feeding. In general, the fixing jig 7 is integrated with the feeding lever 14 of the automatic feeding means 13 by fixing means 8 such as screwing as shown in FIG. The automatic feeding means 13 includes a pulse motor (not shown) for x-axis and y-axis controlled by a microcomputer, and a transmission member such as a rack and pinion that connects the pulse motor and the feed lever 14. And a feed lever 14 driven by the conductive member.

<Problems to be Solved by the Invention> As described above, since the fixing jig 7 is connected to the automatic feeding means by the screw fixing means 8 which is not easily attached and detached, the sewn object including the resin frame and the half net is sewn. It is necessary to set the set 5 on the fixing jig 7 directly at the sutured portion. At this time, as shown in the figure, the space 1 between the sewing machine needle 15 and the fixing jig 7 is narrow (usually 20 mm), and the setting workability is poor. At this time, the net may be caught by the sewing machine needle and damaged. Since the set workability is poor, the set work time becomes long, and consequently, the idle time of the sewing machine operation becomes long and the operation rate of the sewing machine decreases.

Further, the half nets of the insert have different shapes from each other, and the fixing jigs also have different shapes (see FIG. 1).
Therefore, it is impossible to manufacture the set inserts one by one, because the fixing jigs 7 need to be changed alternately, and work efficiency is reduced. In particular, it was difficult to continuously transfer the assembled inserts to the pad forming process in a flow work.

It is an object of the present invention to provide a jig setting device for fixing a sutured set that can solve the above problems.

<Means for Solving the Problems> The present invention solves the above problems by the following configurations.

In a jig set device for fixing a set to be sewn attached to a sewing machine main body of an automatic sewing machine, the sewing machine main body automatically feeds a fixing jig of the set to be sewn together with a pressing member for pressing the set to be sewn. The automatic feeding means and the fixing jig have a locking means interposed between the automatic feeding means and the fixing jig for connecting the fixing jig to the automatic feeding means with one-touch operation. A jig transport carriage provided with at least a pair of feed-in slide rails, from which a pair of holding slide rails are formed protruding from the means in the direction of the sutured portion, and the fixing jigs can be fed into the holding slide rails. A jig setting device for fixing a set to be sewn, comprising:

<Embodiment> An embodiment of the present invention will be described below with reference to FIGS. The same parts as those in the above-described example are designated by the same reference numerals, and similar parts are designated by corresponding reference numerals with suffixes, and the whole or part of the description is omitted.

Further, in this embodiment, one of the splits of the pad insert set is set as the A type and the other is set as the B type, and the set insert is manufactured by alternately stitching them. Then, the fixing jig used for each is 7A,
7B.

The jig setting device for fixing the sutured set of the present invention is attached to the sewing machine body of the automatic sewing machine M as shown in FIG.

This sewing machine body is provided with a jig 7A (7B) for fixing the set to be sewn.
And a pressing member 11 for pressing the set to be sewn, and an automatic feeding means 13 for automatically feeding. Up to this point, the configuration is the same as the above-mentioned example.

In the above structure, first, the fixing jig 7A is provided between the automatic feeding means 13 and the fixing jig 7A (7B).
There is a locking means for connecting (7B) to the automatic feeding means 13 with one touch. In the illustrated example, it is as follows.

The fixing jig 7A has lock pins 9 on both upper surfaces on the base side.
A is formed. On the other hand, a pair of lock holes 12 and 12 are formed at the base of the pressing member 11 which is integrated with the automatic feed means and is a part of the automatic feed means, corresponding to the lock pins 9A and 9A. . A lock pin 9B is similarly formed on the other fixing jig 7B.
At this time, the only difference between the lock pins 9A and 9B is the difference in length. Due to this difference in length, the lock pin 9A,
When 9B is fitted in the lock hole 12, the presence or absence of protrusion from the upper surface of the pressing member 11 is detected by a photoelectric tube or the like (not shown), and the detection signal is input to the microcomputer, and the microcomputer detects the next stage. In the stitching process, the feeding means can instruct to perform a feeding movement corresponding to the jig. Further, the shape of the end of the fixing jig may be changed depending on the product type, and it may be detected by a photoelectric tube or the like and a detection signal may be sent. The locking means is not limited to the above-described configuration, and may be detachable from the feed lever 14 by a spring clip or the like with one touch.

Next, the automatic feeding means 13 is integrated with a pair of holding slide rails 21 and 21 that sandwich the sutured portion and project in that direction.

In the illustrated example, the slide rails 21 and 21 are the feed lever 1
4 are integrally formed to project from both side portions of the slide rail 21, and the slide rails 21 and 21 are fixed on the fixing jig 7A (7
B) is a plurality of pairs of rollers 10 formed on both sides of the lower surface thereof.
A roller group consisting of is engaged to enable traveling.
Here, the roller group is not inevitable, but the fixing jig 7A.
Grooves corresponding to the rails may be formed on both sides of (7B) to eliminate the roller group. Further, it can be replaced by another conventional sliding means.

Further, the holding slide rails 21 and 21 are fixed to the fixing jig 7
A jig transport carriage 25 having at least a pair of feed slide rails is provided so that A (7B) can be fed.

In the illustrated example, two pairs of feed-in slide rails 23 and 23 are formed, and one carriage 25 is used to form a pair of fixing jigs 7.
A and 7B can be held and conveyed. Here, trolley 2
The conveyance means 5 is a roller conveyor 27,
A caster may be attached to the belt conveyor and the dolly, and the rail conveyor or the trolley may be run on the rail or the ground. Also, the trolley is
It may be configured such that one unit can hold one fixing jig.

A positioning stopper (not shown) is preferably attached to the conveyor in order to reliably stop the carriage 25 at a fixed position. Furthermore, when the transporting means is automated, it is desirable to be able to stop automatically with a limit switch or the like. It should be noted that, although it is outside the scope of the present invention, it is also conceivable that a person directly carries the fixing jig between the holding slide rails.

Next, a usage mode of the above-mentioned embodiment will be described. Here, the fixing jig and the pressing member are moved or rotated manually or automatically.

As shown in FIG. 2, in the A type fixing jig 7A,
The half net 3A and the resin frame 1A are set. Here, the fixing jig 7A includes the rails 23, 23 of the carriage 25.
Set above, the rails 23, 23 are in the same row as the holding slide rails 21, 21 respectively.

Next, as shown in FIG. 3, the fixing jig 7A is pushed into the sutured portion, that is, the position immediately above the needle plate 19, that is, until it abuts on the stopper surface 14a formed on the feed lever 14. At this time, since the holding slide rails 21 and 21 and the feed-in slide rails 23 and 23 are on the same row, they can be smoothly pushed into a predetermined position.

Then, the pressing member 11 is tilted down to press the sutured set. At this time, the lock pin 9A of the fixing jig 7A is fitted into the lock hole 12 of the pressing member 11, and the fixing jig 7A is
It is fixed immovably on the rails 21 and 21. And
The lock pin 9A is in a state of protruding to the upper surface of the pressing member 11.

Next, a start switch (not shown) is turned on. Then,
Since the signal "present" of the lock pin 9A projecting from the upper surface of the pressing member 11 is input to the microcomputer from the photoelectric switch, the pulse motor is driven by the command from the microcomputer, and the feed lever 14,
That is, the fixing jig 7A is caused to perform an A type suturing motion, and a predetermined, ie, A type, suturing operation is performed. A
In the case of the same stitching pattern of B type, the output by the photoelectric switch is not necessary. During this sewing operation, as shown in FIG. 1, the half net 3B and the resin frame 1B are set on the B type fixing jig 7B to complete the setup operation.

After completing the A-type suturing work, the pressing member 11 is raised and the fixing jig 7A is pulled out to the front. And trolley 2
5 in the direction of the white arrow to fix the B type fixing jig 7
B is set to a position where it can be fed to the suture site. That is, the feed-in slide rails 23, 23 and the holding slide rails 21, 21 are arranged in a line. Then, the work from above is repeated. It should be noted that the removal of the one-sided crack of the insert after the stitching is performed during the B-type stitching operation.

<Operations and effects of the invention> As described above, the jig setting device for fixing the sutured set of the present invention automatically feeds the fixing jig between the automatic feeding means and the fixing jig with one touch. Locking means that can be coupled to the means is interposed, a pair of holding slide rails are formed from the automatic feeding means so as to protrude in the direction with the sutured portion in between, and at least the fixing jig can be fed into the holding slide rails. A jig carrier cart provided with a pair of feeding slide rails is arranged. By having the above characteristics, the following operational effects are exhibited.

(1) Since the fixing jig can be attached to and detached from the automatic feeding means with one touch, the set of the set to be sewn consisting of the resin frame body and the half-divided net to the fixing jig is at a position different from the sewn site, that is, It can be performed at a site where there is no interference member such as a sewing machine needle. Therefore, the workability of setting the set to be sewn is good, and there is no danger of the net being caught on the sewing machine needle and being damaged as in the conventional case. In addition, the set workability is good, and the next sewing operation can be set up while the sewing machine is operating, which significantly improves the operation rate of the sewing machine.

(2) Even if the insert halves have different shapes from each other and the fixing jigs have different shapes, the fixing jigs 7 can be alternately set up for the next sewing operation, and they can be assembled one by one. It becomes possible to manufacture inserts. Therefore, the set inserts can be manufactured one by one, and the set inserts can be continuously transferred in the pad forming process.
