Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that feeds out a long length of fabric into fixed size units, and more specifically, the present invention relates to a device that feeds out a long length of fabric to a fixed size, and more specifically, a device that feeds out a long length of cylindrical knitted or woven fabric to a fabric processing device, such as a fabric cutting device. It relates to a sending device.

BACKGROUND ART Conventionally, in manufacturing underwear made of cloth, there is a step of cutting a long piece of cloth to obtain cloth for the body, sleeves, gossamer, etc.

Normally, in this process, a long length of fabric is cut using a spreading machine, but after the fabric is spread, it is cut into pieces of specified size.
Next, the fabrics that have been cut to size are stacked one by one while also inspecting the fabric, and then the stacked fabrics are cut into the desired shape, which requires a lot of man-hours and a lot of manpower.

Also, when cutting laminated fabric, if the cutting line is, for example, a complicated curve or a sharp mountain shape, if you try to cut this by hand, you will need to cut the area of the fabric, as well as the required fabric area. A play piece is required to facilitate manual half-cutting work.

That is, the fabric width and fabric length are required to be larger than necessary, which increases the amount of cutting waste and reduces the yield of cut fabrics.

In order to solve this problem, there is a need to develop a means to feed out a long piece of fabric in fixed size increments and continuously and automatically cut it into the desired shape. For example, the means for feeding out cylindrical dough into fixed sizes is a particularly important issue.

That is, regardless of whether it is cylindrical or flat, long fabrics are flexible and easily deformable, making it extremely difficult to feed them to a fixed size, and furthermore, the fabric expands and contracts during feeding. For this reason, it is becoming increasingly difficult to dispense it in a quantitative manner.

If accurate and smooth unwinding or unwinding of each length of long fabric is not guaranteed, fabric processing in the next process, such as fabric cutting, will be disrupted, which will not only reduce the fabric yield but also cause damage to the finished product. This will lead to a decline in the quality of underwear.

In view of the above-mentioned circumstances, the inventors of the present invention have discovered that when feeding out a long piece of fabric at regular size intervals, the fabric is placed on a core frame and fed out while being guided to maintain its shape. Hold the dough with a presser foot and send it out, and at this time,
By driving the pair of dough feed-out rotors in synchronization, there is no expansion or contraction during the dough feed-out process.
Moreover, they have succeeded in providing a device that not only provides accurate positioning but also has a simple configuration and accurate interlocking between each device.

In order to achieve such an object, the present invention provides a device for feeding out a long cylindrical fabric, which includes a pair of fabric feeding rotors having mutually meshing gears and interlocking with each other in synchronization; A core material that holds the clamped long fabric; It is overlapped with this core material, has a cutting edge of a desired shape along the fabric cutting line at the fabric feeding end, and is capable of reciprocating in the fabric feeding direction. a formwork; a formwork driving means for reciprocating the formwork in the fabric feeding direction; a rack that engages with a drive pinion provided on the rotary body and moves along with the reciprocation of the formwork; a rotary body; A one-way clutch that is interposed between the drive pinions and connects with the drive pinion to rotate only when the mold moves forward in the dough feed direction to drive the rotating body synchronously in the dough feed direction; It is characterized by comprising a freely movable dough presser;

The operation of the dough feeding device A according to the present invention will be explained in detail, and the related operations of the subsequent devices B to E will be explained for reference.

In FIGS. 8 and 9, a long tubular knitted fabric Q is attached to the guide roller 3 and the guide plate 2, and then to the core material 19.

When the fabric Q is a flat fabric, it is placed on the core material 19 and, in short, is fixed.

At this time, the fabric Q is brought into a swollen state by the eccentric rollers 26, 27, and 28 of the positioning and locking device 24 provided on the core material 19, as particularly illustrated in FIGS.
As shown in the figure, the left and right side edges 22 of the guide arms 21 of the core material 19 take a feeding preparation position that prevents the fabric Q from shifting in the width direction, and the feeding end of the fabric Q is set at the cutting edge 6a of the formwork 6. The cylinder device 35 is positioned at
The fabric presser body 30 advances toward the formwork 6 through the extension of the fabric Q, and presses the fabric Q (see FIG. 8, 1).

Next, as shown in FIG. 82, only the small cutting blade 40 in the cutting device B is lowered to cut the cutting edge 40a of the cutting blade 40.
However, when it descends onto the cutter receiving member 39, the cutting edge 40a descends to the position shown by the two-dot chain line 40a outside the edge cutout 6a of the formwork 6, as shown in FIG. be cut.

That is, with the edge of the dough positioned on the cutter receiving member 39 outside the edge molding part 6a of the formwork 6, the cutting edge 40a is
When the material is lowered onto the cutter receiving member 39 and the material is cut, the cutting edge 40a descends along the outer edge of the edge molding portion 6a, so that the material is accurately cut without any deviation in shape or dimension. is the cutting waste.

Thereafter, the tubular knitted fabric A is moved to the right in the figure, and this movement is performed by the extension operation of the drive means 15 after the half-cut cutting blade 40 is raised and retreated.

That is, the piston ram 17 of the driving means 15 is connected to the formwork 6 as shown in FIG. Since it is movable, the dough Q held between the dough presser 30 and the formwork 6 is moved to the right as shown in FIG. 8.

Along with this forward movement of the conveying member 4, a pair of dough feed rotary bodies 8 rotate in the dough feeding direction in synchronization with the forward movement of the formwork 6, and the dough is moved in a state where the core material 19 prevents the dough from swaying laterally. Fixed size feed of fabric is guaranteed.

That is, a rack 7 is formed on one side of the conveying member 4 as shown in FIGS. 1 and 3, and a pinion 14 is mounted on this rack 7.
3, the forward movement of the conveying member 4 causes the pinion 14 to rotate about its axis, and in FIG. 3, the upper fabric delivery rotary body 8 is actively rotated about its axis.

The upper dough feeding rotary body 8 and the lower dough feeding rotary body 8 are connected to each other by synchronized interlocking means using left and right sets of gears 12 and 13. It is actively rotated in synchronization with the movement of the formwork 6 in the direction.

At this time, as shown in FIGS. 5 and 6, the eccentric rollers 26, 27, 28 of the positioning and locking device 24 separate the upper and lower parts of the material Q from each other as the material Q is fed, and the material is fed out. Since it is engaged with the rotating body 8, the core material 19 secures the proper position even when the fabric is fed, and the fabric does not get damaged or expand or contract due to the 80 rotations of the rotating body, and the left and right edges of the core material 19 Accurate fixed-dimension feeding is performed in a state where lateral wobbling due to 22 is prevented.

As shown in FIG. 8, during the fabric feeding process, the cut waste T shown in FIG. 9 is pushed forward by the formwork 6 and collected into the collection box 42 by air suction.

Next, as shown in FIG. 8, the conveyance body 44 in the relay conveyance device C moves to the left in the figure and is superimposed on the lower surface of the formwork 6 and waits, and the fabric presser body of the relay conveyance device C After pressing the dough Q at 48 and 50 and releasing the dough presser 30 provided in the formwork 6 through the contraction operation of the cylinder device 35, the formwork 6 is moved back as shown in FIG. let

That is, when the fluid cylinder device of the drive means 15 shown in FIG. It is.

At this time, even if the pinion 14 is engaged with the rack 7 of the conveyance member 4, this pinion 14 has a one-way clutch built therein, and does not rotate the fabric delivery rotor 8 depending on the backward movement of the formwork 6. Therefore, there is no shrinkage of the fabric Q, and since the fabric Q is pressed by the presser body 48.degree. 50, the occurrence of shrinkage is completely prevented.

Therefore, even if the formwork 6 moves back as shown in FIG. 8, the fabric does not sag because the conveying body 44 of the relay conveying device C supports the leading edge of the fabric.

Thereafter, the fabric presser body 30 provided in the formwork 6 advances against the formwork 6 through the extension of the cylinder device 35 and presses the fabric Q, and the large cutter 40 of the cutting device B and the small The cutter 41 is lowered together as shown in FIG. 8, and a sizing material R having a desired shape is obtained as shown in FIG. 9, FIG.

During the cutting operation of the cutting device B, the guide regulating device 37 restricts the horizontal vibration of the formwork 6.

Thereafter, the cutters 40, 41 of the cutting device B and the fabric presser body 48 of the relay conveyance device C rise as shown in FIG. Both are moved to the right through the external cylinder device as shown in FIG. 8.

At this time, since the formwork 6 supports the fabric Q and also holds the fabric Q with the fabric presser 30, the fabric Q is fed by a fixed size from the X position to the Y position in the same way as described above. Become.

In other words, as the formwork 6 moves forward, the material feeding rotary body 8 is synchronously driven in the feeding direction through the engagement of the rack 7 and the pinion 14.

In addition, in the above specific example, when the formwork 6 moves forward, the carrier 44 is placed far from the sending end of the formwork 6 (see FIG. 8, 3).
Although the carrier 44 is placed on the lower surface of the form 6 before the form 6 is retreated, the carrier 44 may be placed in advance as shown in FIGS. 1 to 9.

Further, after the relay conveyance device C moves onto the stacking device and the fabric presser body 50 is released, the relay conveyance device 44 moves to the left in the figure until it reaches the bottom surface of the formwork 6, as shown in FIG. 8 and 9. Then, the fixed size fabric R is transferred to a stacking device.

Each time this process is repeated, the stacking device is lowered one after another, and after stacking the required number of sized fabrics R on the device,
The conveyor 51 of the stacking device rotates to the right in FIG. 8 and transfers to the final conveyance device E.

As described above, the present invention has the following advantages as a device that feeds a long cylindrical fabric to a cutting device at regular size intervals.

A core material to which the cylindrical fabric is attached is provided, and this core material is locked and clamped by a pair of fabric feed rotating bodies, so when the cylindrical fabric is fed out, the fabric is shaped by the core material and fed in. There is no lateral vibration of the cylindrical fabric.

In addition, since the cylindrical fabric is supported by the formwork and pinched by the fabric presser before being sent out, combined with the core material, the cylindrical fabric does not sway laterally.

Furthermore, the pair of dough feed rotors rotates in the dough feeding direction only when the mold moves in the dough feeding direction, and is synchronized with the movement of the mold, so there is no need to forcibly stretch the dough. , guarantees a constant feed amount.

Moreover, the feeding of the dough by this rotary body is accomplished only by a rack interlocked with the formwork, a drive pinion engaged with the rack and provided on the rotary body, a one-way latch, gears, etc. It is simple and useful in terms of manufacturing and assembly.

In particular, since the reciprocating movement of the formwork and the dough feeding rotation of the rotating body are linked by the above-mentioned set of gears and one-way clutches, there is a greater possibility of delays and malfunctions than if they were linked by electrical equipment. Therefore, it is advantageous that the fabric is prevented from expanding or contracting itself and can be delivered accurately, thereby preventing deterioration of the quality of the product.
