Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a marking device that makes marks on each sheet of laminated woven fabric by one operation.

[Conventional technology]

As a device that marks the same position on each layer of woven fabric in one operation, as a means of marking at the same position on multiple layers of woven fabric, making it advantageous for cutting, sewing, etc. of clothing fabric, and adapting it to mass production. For example, Tokukaisho
Those described in No. 53-59560 or Japanese Utility Model Publication No. 57-43851 are known.

In these devices, a tube needle communicating with an ink tank is moved up and down in conjunction with a pump device formed by a cylinder and a plunger to penetrate the laminated fabrics.

[Problem that the invention attempts to solve]

In the above-mentioned conventional system, a fluid cylinder device is used to move the tube needle up and down, and since this mechanism is used in combination with an ink extrusion pump device, the structure is extremely complicated and requires a lot of effort to maintain and manage. Also, there was an inconvenience that the cost was high.

[Means for solving problems]

The present invention eliminates the above-mentioned conventional disadvantages and uses a gear mechanism driven by an electric motor to move the marking tube needle up and down, thereby simplifying the drive mechanism, facilitating manufacturing, and reducing maintenance management. This provides a marking device that is easy to use, easy to operate, and can be obtained at a low cost. The gears attached to the drive shaft rotate together with the shaft, but move up and down along the shaft, and the gears attached to the screw shaft engage with each other. is screwed into a screw shaft, and as the gear rotates, the elevator plate supports these gears together and moves up and down together, the upper end communicates with the ink tank, and the lower end faces toward the laminated fabric. A thin tube needle is attached, and the middle of the tube needle is movably held by a support piece provided between the base plate and the elevator plate so as to move up and down guided by a drive shaft and a screw shaft. The upper and lower surfaces are supported by coil springs so that they can move up and down.

[Effect]

In the present invention, as shown in the illustrated embodiment, when a substrate 1 is placed on a laminated woven fabric a and a motor 2 is driven to rotate a drive shaft 3, the screw is engaged with a gear 5 on the shaft. The gear 6 on the shaft 4 rotates. In this case, since the screw shaft 4 is fixed, the gear 6 rotates and moves downward from the solid line in the same figure along the screw shaft 4. Along with this, the elevator plate 7 is also connected to the drive shaft 3 and the screw shaft 4. The pipe needle 8 is guided and moved downward, and the tube needle 8 attached to the lifting plate 7 is moved downward and inserted through the laminated fabric a. The tip of the needle 8 is a conductive plate 11
When the solenoid 12 comes in contact with the on-off valve 1, the solenoid 12 is energized.
0 is opened and the ink in the tank 9 is sent into the tube needle 8 and discharged from the tip. At this point, the motor 2 is switched to change the direction of rotation, and in order to change the direction of rotation of the gears 5 and 6, the elevator plate 7 and the tube needle 8 move upward, and the needle 8
During the upward movement, ink is discharged from the tip to mark each layer of the laminated woven fabric a, and the cloth is stopped at the upward movement position. While the needle 8 is moving up and down, the support plate 16 holding the middle of the needle 8 moves up and down while maintaining the horizontal position while expanding and contracting the coil spring 15, thereby holding the needle 8 in a vertical position.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

A drive shaft 3 rotated by a motor 2 and a screw shaft 4 parallel to the shaft 3 were provided on a substrate 1 placed on a multilayered woven fabric a. In the illustrated example, the screw shafts 4 are arranged on both sides with the drive shaft 3 in the middle, both screw shafts 4, 4 are fixedly established on the substrate 1, and the drive motor 2 of the drive shaft 3 is connected to the screw shafts 4, 4, It was installed on the receiving frame 1a bound to the upper end of the frame 4. Therefore, the motor 2
In the case where it is installed on a support frame (not shown) separately provided on the base piece 1, the two screw shafts 4 are not required as described above, and a single screw shaft can be used without any problem.

Gears 5, 6, and 7 are attached to the rotating shaft 3 and the screw shafts 4 and 4 on both sides, respectively, and engaged with each other. Insert the gear 3 into the square hole, or insert the gear 3 into the drive shaft 3.
A key groove in the axial direction is provided in which the gear 5 may be fitted with a key, so that the gear 5 rotates together with the shaft 3 but can move up and down in the axial direction of the shaft 3.

Also, the gear 6 is attached by screwing into the screw shaft 4, and the screw shaft 4 is fixed to the base piece 1, so when the gear 6 rotates, the gear 6 moves up and down along the shaft 4 due to the screw engagement with the shaft 4. I made it move.

An elevating plate 7 is provided which encases and supports these gears 5 and 6 and moves up and down together with the up and down movements of these gears.A tube needle 8 is provided on this with its lower end facing the laminated fabric a, and its tip The ink was communicated with the ink discharge port of the ink tank 9 via the on-off valve 10, and the on-off valve 10 was opened at appropriate times to send ink into the pipe needle 8 and discharge it from the lower tip.

The opening/closing operation of the on-off valve 10 is performed, for example, when the tube needle 8 moves downward and passes through the laminated fabric, and the tip of the tube needle 8 comes into contact with the conductive plate 11 laid on the underside of the laminated fabric. The power supply circuit of the operating solenoid 12 is closed, and the normally closed on-off valve 10 is suction operated to open the ink discharge passage.
In the drawing, 13 indicates an ink flow rate control valve.

In the illustrated example, the pipe needle 8 attached to the elevator plate 9 is
A gear 14 is fixed to this, and the gear 13 is engaged with the gear 6 screwed into the screw shaft 4, so that the rotation of the drive shaft 2 causes the tube needle 8 to be moved together with the gear 14 through the gears 5 and 6. The tube needle 8 is moved up and down by the vertical movement of the elevator plate 7, which rotates and moves up and down together with the gears 5 and 6, and is inserted into and extracted from the laminated fabric a. The above rotation of the tube needle 8 facilitates insertion and extraction, and when the tube needle 8 is extracted, ink is ejected from the tip of the tube needle 8 so that markings are made on each sheet of the woven fabric a. One of the supporting pieces 16 is installed horizontally by loosely fitting onto the drive shaft 3 and the screw shaft 4 between the base piece 1 and the elevator plate 7, and the upper and lower surfaces are held by coil springs 15 fitted onto each shaft 3, 4. provide one or more sheets,
The middle part of the tube needle 8 is movably held by the support piece 16, and the vertical posture of the tube needle 8 is always maintained, so that the tube needle 8 can be inserted into and removed from the fabric a accurately.

Incidentally, the motor 2 is of a reversible type so that the direction can be changed, so that when it rotates in the normal direction, the tube needle 8 is moved downward, and when it is rotated in the reverse direction, it is moved upward.

[Effect of idea]

According to the present invention, the tube needle is mounted perpendicularly to the lifting plate, and the tube needle is inserted into and extracted from the fabric by the vertical movement of the lifting plate. Since the movement is carried out by a shaft, the mechanism is extremely simple and the operation is accurate.Also, while the tube needle moves up and down with the lifting plate, it is held in the middle by a support piece, so it does not tilt during up and down movement. Therefore, it has the effect of making it possible to mark a large number of woven fabrics at accurate positions without causing any deviation in the position of the markings.
