Abstract

PURPOSE:To handle a variety of sewed products having different sizes by forming right and left spit plates for automatically regulating the length of a retaining plate in frame states, and providing sub plates separable with the surface of a base plate inside the plates. CONSTITUTION:When the size of a product is varied, novel needle sewing data is read in a RAM at a standby position such as by a selection button, a start pedal is then pressed, and then a retaining plate 1 opens two split plates 1a, 1b to a maximum limit by automatic control means of an automatic sewing machine, detected by origin sensors, returned to newly selected dimensional data position, the plates 1a, 1b are coupled, cloth (b) is then retained by a retaining pedal to a standby state. When the start pedal is pressed in this state, sewing with new data can be continued. Front cloth is first returned front side down on a base plate (a), developed, retained by sub plates 5a, 5b, then rear cloth is turned at rear side front by covering the upper surfaces of the plates 5a, 5b, front and rear cloths are superposed, placed on the plate (a) in a state that the peripheral edges of the front and rear cloths are suppressed by left and right framelike split plates 1a, 1b to be sewn on the profile.

る。(Prior art) In an industrial sewing machine, the processed fabric that is flattened against the fixed base plate is suppressed by a presser plate, and the sewing machine needle moves up and down at a predetermined position on the plywood. 1. Join the contours of the regular-shaped sewing product by moving it back and forth and left and right using automatic control means in the x and y axis directions of the automatic sewing machine. After that, it is automatically returned to the standby position to prepare for the next sewing process L, and this process is repeated to perform continuous sewing. For example, JP-A-53-89542 discloses a device in which the holding plate is divided into a plurality of parts so that the left and right lengths can be adjusted, and the adjustment means is simplified.

間に無駄が多く作動効率の低下原因となる。(Problems to be Solved by the Invention) In the above-mentioned automatic sewing machines and conventional sewing machines, the fabric presser plate for shaping the fabric used in the shell is adjusted to the dimensions of the sewn product each time when the dimensions of the sewn product differ. It is necessary to replace the presser plate with a suitable one, and it takes time to attach and detach it, which wastes a lot of labor and time and causes a decrease in operating efficiency.

In terms of expanding and contracting the length, the problem of being able to deal with shaped products of different dimensions without having to be replaced is solved, and the movable plate can be moved and adjusted step by step using a large number of small engagement holes. , the operating means is characterized in that it is made movable by simply loosening the flat head screw, and the expansion and contraction state is stabilized by tightening the flat head screw.In this case, the means for loosening or tightening the flat head screw is unknown, but There is no other automatic means other than manual operation for the above operation, and the length adjustment is also step-by-step, making manual fine-tuning difficult and wasteful of labor and time, just like replacing the presser plate. A decrease in operating efficiency due to this is unavoidable.

At a predetermined standby position, the presser plate is moved with the processed fabric suppressed by the vertical movement of the presser plate to perform the sewing operation by the automatic braking mechanism, and after completing the predetermined stitching, it returns to the standby position again. Returns to the original position, replaces the processed material at that position, and repeats the next sewing. However, when the dimensions of the sewn product change, if the appropriate one is selected from the data set in the initial input, the sewing machine returns to the standby position. The locking operation of the locking means is released and the two divided plates are separated, and the separated divided plate is immovably locked by the second locking means, so that the other divided plate is The dividing plate is moved by a predetermined amount by an automatic control means based on the above selection data to automatically adjust the length of the presser plate formed by both dividing plates, and then the first and second locking means are respectively restored to separate the two dividing plates. Sewing can now be performed using new data while the plates are connected together.

の効果を有する。(Effects of the Invention) According to the present invention, sewing is performed by suppressing and moving the processed fabric from the standby position on the plywood to the sewing operation position by the automatic control means in the x and y axis directions of the automatic sewing machine, and the specified sewing is completed. After that, the presser plate for the processed fabric that is returned to the standby position is divided into two left and right divided plates, and one of the divided plates is integrally joined or separated from the other divided plate.
Since the locking means and the second locking means capable of holding the dividing plate immovably in the standby position are provided, when the dimensions of the product change due to the size of the product, new data can be stored in the standby position and the first locking means can hold the dividing plate immovably in the standby position. By releasing, both dividing plates are separated,
Then, one dividing plate is kept immovable by the second locking means, and the other dividing plate is moved and adjusted by the automatic control means in the x and y axis directions of the automatic sewing machine according to the new data to automatically and accurately join to a predetermined dimension. This allows you to immediately start sewing the next product, which greatly improves work efficiency and saves labor compared to the conventional method of replacing the fabric presser or manually adjusting the split presser plate. This has the effect of saving time and making the sewing work by automatic control even more advantageous, and also making the sewing process more convenient by using a secondary plate if necessary.

おける加工生地押え装置。[Scope of Claims] 1. Automatic control means for controlling the presser plate holding down the processed fabric in the x and y axis directions of the automatic sewing machine together with the fabric at a standby position relative to the sewing operation position of the sewing machine needle on the fixed base plate of the automatic sewing machine. The machine is moved back and forth from side to side and returned to the standby position after completing the specified sewing process.
The presser plate is divided into two left and right parts, one of which is connected to the automatic control mechanism of the automatic sewing machine, and the other dividing plate is provided so that it can be separated from the connected dividing plate. A first locking means capable of connecting the plates together and releasing the connection in the standby position, and a second locking means capable of locking the separated divided plates in the standby position which are normally released, are provided. A workpiece material presser for an industrial sewing machine, characterized in that the other dividing plate is moved by a set amount by the automatic control means to automatically adjust the length of the presser plate by both dividing plates. 2. The two left and right divided plates constituting the presser plate are each formed into a frame shape, and a sub-plate is provided inside each of them, which can be moved toward and away from the base plate surface regardless of the frame-shaped divided plates. A processed material pressing device for an industrial sewing machine according to claim 1.
