Description

DETAILED DESCRIPTION OF THE INVENTION +3) The present invention relates to a method and apparatus for sewing reinforcing interlining material for the upper collar of clothes in a self-QJ manner.

For more information about the conventional reinforcing interlining for the upper collar, that is, the reinforcing interlining that is used as a single piece on the back side of the upper collar of men's and women's clothing. As shown in Figure 1, the front interlining (0) and the back interlining (0 wings) are arranged in several rows above and below (
This reinforcing interlining (0) is usually sewn by hand using a human sewing machine, and is made by stitching the reinforcing interlining (0) over the top and bottom. The fabric was constructed while being fed, and there was no automatic construction machine for this construction. Therefore, reinforcing interlining (0) obtained in addition to construction workers
The number of workers involved in cutting out the die and constructing the upper collar is usually on the side, which is not desirable from the point of view of labor saving. In addition, when hand-feeding using a sewing machine, not only does the straight stitching of the hemline stitch become poor, but also the front and back top interlinings are usually cut biased against the warp and weft of the fabric, so the front and back interlinings are separated. There was a fatal problem in that the finish of the stitching deteriorated in areas where the expansion and contraction ratios were different, and the intervals between the sewn rows tended to be uneven.

On the other hand, an automatic upper collar composing machine has recently been provided (4), but the configuring mechanism of this machine is to continuously feed the fabric while simultaneously performing scoop stitching with a sewing machine needle. If the sewing machine needle is distorted during assembly, the sewing finish will not necessarily be good, and the sewing machine needle may be damaged during assembly work.

The invention of the tree was made in consideration of the points mentioned above, and since it is an automatic composing machine, it can produce the same finish as when hand-feeding fabric to a sewing machine, and also eliminates the poor straightness and stitching that are common with hand-feeding. An object of the present invention is to provide an automatic sewing method and a device thereof that do not cause irregularities in sewing intervals.

The purpose of the above is that the mechanism that fully grasps and feeds the two pieces of interlining to be sewn performs intermittent feeding in synchronization with the sewing machine while the sewing machine is sewing, and continuous fast forwarding for other feeding and return operations. This is achieved by automatically selecting two types of movement, intermittent and continuous, using the feed mechanism. According to the present invention, the operator's hand is only required when introducing the interlining material into the device and when taking out the reinforcing interlining material after sewing. By having the worker who was previously working take over this task, only one worker can sew the reinforcing interlining, which can greatly contribute to labor savings. As mentioned above, since the interlining is fed intermittently in synchronization with the machine stitching, it is possible to achieve a better finish on the sewn portion than with conventional hand-feed stitching.

Preferred embodiments of the wooden invention will be described in detail below with reference to the drawings. Figure 2 is a schematic plan view of an apparatus for applying the method of the present invention, and Figure 3 is a side view of the same.

Simultaneously with the operation of the constituent mechanism, the movable table mountain is intermittently moved laterally in synchronization with the first drive system, and the sewing machine (21) performs hemlock stitching.

@Step 4: Both the third and second drive systems are operated continuously to move the table to the starting position of the primary row.)
Go back quickly. Fifth step--Similar to the third step, it is performed by operating the first drive system. The moving table 11) is operated in a tight manner to quickly return to the initial set position. Seventh step: The air cylinder (13) operates to release the grip on the holder (12).

By carrying out such a process, the method of the present invention allows the front interlining material and the back interlining material, which have different elasticity, to be securely gripped along the longitudinal direction of both interlining materials with the holder, and then to be moved laterally in synchronization with the feeding of the thinner. Because both interlining materials are fed intermittently in the direction, the
By eliminating the poor stitching, it becomes possible to sew with good straightness. Furthermore, since the spacing between the rows of the structure is ensured by the vertical feed (K), there is no irregularity in the spacing between the sewing rows.

Inventive device l-J: By programming the desired sewing method in the electric control device (6) in advance, the operator can complete the sewing work by simply introducing and deriving the double interlining metal setting position. This is done automatically.Moving table 11)
Since the holder (12) is installed in the holder (12) and each process is carried out via the two magnetic clutches (43), the structure is simple, there is no mechanical strain, and the product is highly durable. Ru. Since the sewing machine motor (2) and the moving table are synchronously connected by the ratchet mechanism (23), synchronization of intermittent feed in the lateral direction of the moving table (1) is ensured, and the sewing machine motor (2) can be operated with one sewing machine motor (2). Enough.

Since the moving table (1) is equipped with a stepping motor (5) to feed the holder (12) in the vertical direction, the spacing between the sewing rows can be determined accurately. Since the servo motor +33 is used to feed and return the movable table mountain in the lateral direction, the movable table (
1) can enable rapid continuous movement. Sewing machine (21)
By intermittently sending the movable table (1) laterally in synchronization with the constructional movement of the sewing machine (21) only during sewing, it is possible to eliminate the generation of strain on the sewing machine needle.
It is possible to improve the finish of sewing and reduce time and economic losses due to breakage of sewing machine needles.
