Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a sewing device, and more particularly to a sewing device for stitching the edges of a long cloth having a relatively wide width such as curtains and sheets.

[Background of the invention]

Conventionally, a curtain or the like is completed as a product by stitching both edges (upper and lower edges) thereof, and a general electric sewing machine is used for the work. However, according to the work using this general electric sewing machine, since the object is long and has a width, it is difficult to carry out the feeding work, and the weight causes the direction to shift, and the sewing needle is extremely It caused a heavy burden.

[Purpose of device]

The present invention has been made in view of the above-mentioned conventional circumstances, and provides a sewing device which solves such a problem and can smoothly perform a work of sewing both edges of a curtain or the like. Is intended.

[Means for solving the problem]

In order to achieve this object, a sewing device according to the present invention comprises a first roller which rotates in conjunction with a drive motor of a sewing machine and a continuously variable transmission, and a first roller which is arranged at an appropriate interval from the first roller. A sewing machine having an endless belt wound around two rollers along the working direction of the sewing machine, and means for running the endless belt in forward and reverse directions. The rollers are accommodated between a pair of worktables supported by height-adjustable stanchions, the worktables can be brought into and out of contact with the sewing machine by casters, and the endless belts have antistatic processing on the surface. In addition, the meandering prevention is performed in the recess formed in the first roller and the second roller, and a plurality of return rollers are arranged in parallel between the first roller and the second roller. Done It is characterized in that there.

[Action]

With the above-mentioned configuration, the material such as the curtain is advanced on the endless belt along with the sewing work on the sewing machine, and the operator is not burdened.
You can work smoothly.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a sewing device embodying the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a front view thereof.

In these figures, 1 is a sewing machine, and this sewing machine 1
Is an electric type equipped with a drive motor 3 which is turned on and off by a push type power switch 2. A drive shaft 3a of the drive motor 3 is connected to a continuously variable transmission 5 to a pulley mechanism via transmission means 4 such as a V belt or a timing belt.
The electromagnetic clutch 7 is connected via. Here, the pulley in this pulley mechanism is formed with an oblique kerf, and it is not necessary to loosen and move the pulley itself when the belt is unhooked. A shaft 8 is connected to the electromagnetic clutch 7 by a transmission means 4, and the tip of the shaft 8 is connected to one end of a first roller 9 by the transmission means 4. An endless belt 11 is wound around the first roller 9 and a second roller 10 arranged in parallel at a predetermined distance. The surface of this endless belt 11 is antistatic processed,
It is designed to prevent the cloth on which it is placed from being caught. Also, there is a recess in the center of the first roller 9 and the second roller 10.
9a and 10a are formed, and meandering is prevented by engaging a protrusion formed on the back surface of the endless belt 11 therewith.

In addition, the first roller 9 and the second roller 10 are columns 12
・ It is accommodated within the width of the left and right worktables 13a ・ 13b supported by 12, and the adjustment bolts 14 are attached to the columns 12, 12.
・ 14 ... is attached so that the height position can be adjusted. Further, casters 15 and 15 are provided under the supplementary frame that is installed between the appropriate columns 12 and 12, so that the position of the endless belt 11 can be brought into contact with and separated from the sewing machine 1. It can accommodate the width of fabric such as curtains. At that time, the workbench 13a is in a superposed state,
The overlapped portion does not protrude so that no void is generated, and a key groove 8a attached to the base end of the shaft 8 corresponds thereto. Further, the workbench 13b also serves as a side wall surface cover.

Further, a plurality of return rollers 16, 16, ... Are arranged side by side at a predetermined interval between the first roller 9 and the second roller 10, and the return rollers 16, 16 ... Operated by the workbench 13b
It is controlled by a timer inside a box housed inside and is controlled by abrupt switching, and is executed by operating a power unit 18 dedicated to reverse rotation. In addition, numeral 19 in the figure is a receiving box for the cloth to be sent.

The sewing apparatus according to this embodiment is configured as described above. When a carten or the like having a length and a width is placed on the endless belt 11 and the sewing machine 1 performs the sewing operation on the edge thereof, the sewing machine 1 Since the endless belt 11 runs along with the work speed of (1), most of the curtains and the like, which have been very obstructive in the past, proceed with the sewing work, which makes the work very easy. Further, when the other end of the curtain or the like is also sewn, the endless belt 11 is moved backward to return the position, and the positions can be exchanged for work.

[Effect of device]

As described above, according to the sewing device of the present invention, the work of sewing the edge of a long fabric having a width can be smoothly performed without burden, and the work can be facilitated and made more efficient. It has become a thing.
