Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an industrial sewing machine device used to perform stitching such as quilting on a futon or the like in a desired sewing pattern.

In general, this type of sewing machine device has a sewing machine body mounted on a machine frame, in which a sewing machine head equipped with a needle and a sewing machine base equipped with a corresponding hook are operated in synchronization. On the other hand, a support base is provided between the head part and the base part to support an article to be sewn, such as a futon, so as to be able to move freely in the front-rear direction and the left-right direction relative to the head part. In this type of sewing machine device,
When moving the needle on the surface of the workpiece such as a futon, the position, spacing, and direction of the sewing lines can be freely changed to create a large number of stitches, including straight lines, zigzag, curved lines, circular stitches, and a variety of other stitches. It is desirable to be able to freely sew a wide variety of complex sewing patterns in which lines are combined in various shapes, and to be able to sew them quickly and efficiently in a short period of time. In response to the need for increasingly complex and diversified designs of sewing patterns for products such as quilted futons, there has been an urgent need to supply them at low cost.

This type of sewing machine device, which has been widely used mainly for making it possible to freely sew complicated and diverse sewing patterns, has only one main body of the sewing machine, consisting of a head section and a base section, mounted on the machine frame. It was one-headed. In the case of this type, the - sewing machine bodies are fixedly installed in fixed positions on the stationary machine frame and are operated for sewing, while the workpiece support base is moved in the front, back, left and right directions. The method is the most common. However, this method requires a large area for installation due to the movement of the support stand back and forth, left and right, so in order to reduce that area, we decided to use the machine frame 1]
The IJ is installed so that it can be moved in the rearward direction, and the head and base of one sewing machine are synchronized with each other using a pair of upper and lower guide members that are parallel to each other and are provided on the machine frame. Japanese Patent Publication No. 56-8638 has already known a system in which the sewing machine is guided and supported so as to be movable in the left and right directions in synchronization with each other while performing the sewing operation.

However, in any case, this one-head type is equipped with only one sewing machine body with a head part and a base part. The needle can be moved freely by sequentially tracing all the sewing lines of the sewing pattern on the nine sides of the workpiece, which allows for any desired variety of stitches. Although it is possible to freely sew complex sewing patterns, it has the serious disadvantage that it takes a lot of time to sew and the sewing efficiency is extremely low.

On the other hand, among this type of sewing machine devices, there has conventionally been a multi-head type sewing machine in which a plurality of sewing machine bodies including a head portion and a bottom portion are mounted on a machine frame mainly for improving sewing efficiency. However, in the case of this conventional multi-head type, multiple sewing machine bodies,
The head part and the base part are fixedly mounted in a fixed position on the machine frame in parallel in the left and right direction with a predetermined interval from each other, with the head part and base part corresponding to each other. Even if they could be moved, the mutual spacing settings could only be adjusted slightly at the start of operation, and they could not be moved at all during operation. In this case, while these multiple sewing machine bodies are operated in conjunction with each other to sew simultaneously, the work to be sewn is placed on the support stand and moved linearly or slightly left and right in one direction, front and back. The sewing machine feeds the sewing machine continuously while moving the sewing machine, but also moves the support stand freely in the front-rear direction and left-right direction. The sewing of the sewing lines of each part was divided among the members, and a desired sewing pattern was sewn. Therefore, in this case, a plurality of sewing machine bodies are placed in a fixed position on the machine frame at a predetermined position r1. Although the sewing machine is fixed and immovable at intervals of iJ, it is possible to sew the sewing lines of various parts of the sewing pattern using multiple needles at the same time, which improves the efficiency of sewing. Although it is advantageous, it is merely a matter of ensuring that the needles are moved uniformly at regular intervals and in the same direction, and for this purpose a predetermined method is used so that the sewing lines trace the same pattern. Although it is effective for efficiently sewing a specific relatively simple sewing pattern such as one that consists of sewing lines lined up at intervals, it is not effective for sewing other complicated and diverse sewing patterns. is bad and inconvenient or impossible;
There are major restrictions on the sewing patterns that can be sewn, and a wide variety of complicated sewing patterns cannot be sewn freely.

In view of the above-mentioned circumstances, the present invention is of a multi-headed type,
The head parts and the knife parts of a plurality of sewing machine bodies are installed so as to be guided and supported by a pair of upper and lower guide members of the machine frame so that the corresponding parts can sew individually in synchronization and can be moved in the left and right directions. A support frame for supporting an object to be sewn, such as a futon, is placed between the head section and the base section on a support stand that is movable in the longitudinal direction relative to the machine frame. To provide a sewing machine device which can freely and efficiently sew a variety of desired complicated sewing patterns in a short time by being rotatably installed.
