Description

Detailed Description of the Invention (Industrial Application Field) The present invention is directed to the cutting of woven fabrics, particularly flexible woven fabrics or rubberized woven fabrics used for cuffs, collars, hems and other necessary parts of clothing. In addition, the present invention relates to a flexible woven fabric sheet cutter device for cutting soft felt and other flexible woven fabrics.

(Prior Art) Conventionally, there is an apparatus for cutting flexible woven fabric, particularly when cutting woven fabric into short widths, there is an apparatus that simply cuts the woven fabric supported by rollers using a cutting blade.

However, in conventional fabric cutting devices, even if the fabric supported by a roller is sent out by the roller, the fabric is pushed too much and wrinkles occur before it reaches the receiver that determines the size, and the fabric is not supported by a roller. If you pull the woven fabric while gripping the tip with a roller, the woven fabric will stretch longer than the specified size due to its flexibility, and if you cut it in that state, the cut woven fabric will stretch by the amount that has been stretched. There were drawbacks such as shrinkage and dimensional variations in the cut woven fabric, resulting in defective products that could not be sold as products.

(Problems to be Solved by the Invention) The present invention aims to eliminate the above-mentioned conventional drawbacks.

That is, cutting woven fabrics, especially flexible woven fabrics or clothing cuffs,
Cuts rubber-containing woven fabrics used for collars, hems, and other necessary parts of clothing to specified dimensions without shrinking or stretching them, preventing the occurrence of defective products and efficiently producing products with uniform dimensions. An object of the present invention is to provide a flexible woven fabric sheet cutter device that can cut sheets of flexible woven fabric.

(Means for Solving the Problems) The present invention provides a feed roller 2 and a feed roller 2 provided on a machine base 1.
A gas jet hole 5 that spouts gas upward so as to float the sheet 8 in a path through which the flexible sheet 8 passes between the upper blade 9 and the lower blade 3 that move up and down in front of the sheet 8; An upper receiving plate 6 is provided at an appropriate interval above the gas jet holes 5 so that the sheet 8 does not float more than necessary, and the sheet 8 sent out by the feed roller 2 is floated by the gas from the gas jet holes 5 while being placed above the front of the sheet 8. In addition to feeding the sheet into the blade 9 and the lower blade part 3, a receiver 7 whose dimensions can be adjusted to a fixed size is provided on the machine base 1 in front of the upper blade 9 and the lower blade 3, and the tip of the sheet 8 reaches the receiver 7. When the sheet 8 is cut by the upper blade 9 that engages with the lower blade 3, a receiving plate 11 for receiving the sheet 8 to be cut is provided below the receiving body 7 so as to be movable forward and backward. Woven fabric sheet cutter device.

(Function) In the present invention, the sheet 8, which is a flexible woven fabric that is elastic and has elasticity woven into it, for example, is not pinched, but is moved by a needle roller 13 (instead of the needle roller 13, it is suspended or fed by other means). The sheet 8, which is fed by a device (which may also be fed by a device) and sent out via the feed roller 2, floats up due to the gas ejected from the gas ejection hole 5 when it passes above the gas ejection hole 5.

Then, the lifted sheet 8 contacts the upper receiving plate 6 and passes between the upper blade 9 and the lower blade 3, and its tip hits the receiving body 7 for regulating the size to a certain size, and at the same time it moves below the receiving plate 7. The upper blade 9 descends while riding on a receiving plate 11 that can move forward and backward to cut the sheet 8 to a predetermined size. Immediately after cutting, the receiving plate 11 moves back, so the sheet 8 cut to a predetermined size is transferred to a belt conveyor. 12 and move in the removal direction.

The upper blade 9 is guided by a groove 30 provided in the machine base 1 and moves up and down. Further, the upper end of the receiving plate 11 is swung back and forth by a rod 16 that is movable back and forth, thereby moving the receiving plate 11 back and forth from side to side. The vertical movement of the upper blade 9 and the swinging of the rod 16 are caused by an eccentric shaft 15;
This is done by operating the grooved eccentric cam 18.

Further, these operations are performed in series by power 514 (for example, a motor).

(Example) Hereinafter, the present invention will be explained in detail based on the drawings.

In the present invention, a machine base 1 is provided with a pair of feed rollers 2 for feeding the sheet 8 forward, and a roller 13 with needles planted in the feed roller 2 to feed the sheet 8 while preventing slippage. . Also, at the tip of the feed roller 2, there is a lower blade 3 at the tip.
A lower blade holder 4 is provided, and an upper receiving plate 6 is positioned above a large number of gas ejection holes 5 formed in the inner upper surface of the lower blade holder 4. The lower blade holder 4 is hollow inside, and compressed air from the compressor 10 is introduced into the lower blade holder 4 through the ventilation pipe 31.
Furthermore, the mechanism is such that air is ejected from the gas ejection holes 5. Further, at the tip of the lower blade 3, there is a long hole 32 and a screw 26 for adjusting the tip position of an adjusting rod 34 that regulates the length.
A receiver 7 is provided at the tip of the sheet 8 to position the tip of the sheet 8. A receiver plate 11 is provided below the receiver 7. After the sheet 8 is cut, the receiving plate 11 is configured to move back and drop the sheet 8 downward.

Below this receiving plate 11, the tip of a belt conveyor 12 provided outside the machine base 1 is positioned, and the sheet 8 cut to a certain size is transported to the packaging position, and the sheets are stacked and packaged. do.

As shown in FIGS. 1 and 4, as an example of the operating mechanism of the upper blade 9 and the receiving plate 11, the upper blade 9 connects a power source 14 such as a motor to an eccentric shaft 15 and a rod 16 to the shaft portion 17 of the upper blade 9. The upper blade 9 is guided by the groove 30 and moved up and down. Further, the receiving plate 11 allows the movement of the roller 19 in the groove of the grooved eccentric cam 18 to move the operating rod 21 back and forth through the link mechanism 20, and allows the protrusion 23 provided on the receiving plate 11 to be loosely inserted into the elongated hole 22 at the upper end of the operating rod 21. , converts the back and forth movement of the operating rod 21 into the forward and backward movement of the receiving plate 11.

In addition, as an example of the structure of the belt conveyor 12, an upper main body having the belt conveyor 12 can be moved vertically in parallel by a link mechanism 24. This link mechanism 24 is moved up and down and fixed in position by, for example, a hydraulic cylinder 25.

In the figure, 27 indicates the receiving plate 11 in order to enable the receiving plate 11 to move forward and backward.
29 is a tensilon shaft that applies tension to the sheet 8 fed to the needle roller 13.

Since the present invention is constructed as described above, the flexible sheet 8 is supplied to the feed roller 2 via the needle roller 13, and the sheet 8 is fed by a predetermined size.

Then, the sheet 8 that comes out from the feed roller 2 is transferred to the lower blade holder 4.
When the upper surface is encountered, it is lifted by the gas from the gas outlet 5 provided in the lower blade holder 4, but since there is an upper receiving plate 6 above the gas outlet 5, wrinkles are prevented from forming. . When the leading edge of the sheet 8 sent out in this manner passes through the lower blade holder 4 and reaches the receiver 7,
The upper blade 9 descends and cuts the sheet 8. The timing at which the upper blade 9 descends is determined by the power 1l11 of the feed roller 2 and the upper blade 9.
4 as a common power source, the speed is adjusted through a gear mechanism or the like. In addition, if a different power source is used, the time when the sheet 8 comes into contact with the receiver 7 can be detected by light,
A conceivable mechanism is a mechanism in which the upper blade 9 is operated by rotating the power source 14 based on detection using electrostatic or contact sensors.

Next, in parallel with the cutting by the upper blade 9 or after the cutting is completed, the receiving plate 11 is moved backward, and the cut sheet 8 falls below the receiving plate 11 and is sequentially placed on the belt conveyor 12 located below. At this time, the sheets 8 that have been cut and overlapped one after another on the belt conveyor 12 become thicker and come into contact with the lower surface of the receiving plate 11. The height of the conveyor 12 is reduced. This pertco 2 bear 12
The height adjustment may be performed in accordance with the number of cuttings.

When the cutting of a predetermined amount of sheets 8 is completed, the belt conveyor 12 is operated to tie the cut products with a string and package them.

When changing the width of the seat 8, loosen the screw 26 and adjust the adjustment rod 33 along the long hole 32. After setting the receiver 7 at the desired position and determining the specified dimensions, tighten the screw, and then proceed as described above. Work in a similar process. However, it is necessary to adjust the timing of cutting by the upper blade 9.

That is, when the sheet 8 is spread out during cutting, if the cutting is performed at a timing before spreading, the sheet 8 will be cut before it reaches the receiver 7. Please note that timing adjustment can be performed using light, electrostatic,
If a mechanism for detecting contact with various sensors is built into the machine from the beginning (for example, by attaching the above sensor to the receiver 7 and controlling the power source 14 based on this), no adjustment may be necessary, resulting in labor savings. is also possible.

(Effects of the Invention) As explained above, according to the present invention, when cutting a woven fabric that expands and contracts due to flexibility and causes uneven cut products to be cut into particularly short widths, the woven fabric does not wrinkle. Alternatively, when cutting rubber-containing woven fabric, etc., there is no need to consider the elongation of the rubber because the structure does not require pulling the tip of the woven fabric, and the woven fabric is always kept in the same state due to the gas from the gas outlet. By being supplied to the cutting blade, it is easy to cut to a uniform predetermined length, and there is no variation in the product after cutting, and there is no need to cut the raw material woven fabric additionally, thus reducing manufacturing costs. I can do it. Furthermore, since the position of the receiver can be changed, it is easy to change the width of the sheet.
The cut sheets can be transported and packaged in a stacked state on a belt conveyor, making it easy to process the cut sheets in the next process.The structure is also simple and can be produced in large quantities at low cost. It has excellent effects such as:
