Description

[Detailed Description of the Invention] The present invention relates to a device for feeding out a long piece of dough, for example, a long cylindrical piece of dough, to a fixed size. By using a rack and pinion system and a continuously variable transmission to send the fabric forward, even if the coefficient of friction varies depending on the thickness or type of fabric, etc. It is an object of the present invention to enable fixed-quantity feeding at an appropriate speed by increasing and decreasing the speed of the pinion.

Conventionally, when manufacturing underwear made of cloth, a long piece of fabric is cut to obtain fabric for the body, sleeves, gusset, etc.
For example, it is essential that the body fabric or the like does not contain any defective parts such as fraying, irregular knitting, or damaged parts.

Normally, in this process, a long length of fabric is cut using a stretching machine, but after extending the fabric, it is cut to size, and then the fabric cut to size is cut into one piece. It takes a lot of man-hours and a lot of manpower to manually stack the fabric one by one while also inspecting the fabric, and then cut the stacked fabric into the desired shape.

In addition, when cutting laminated fabric, if the cutting line has a complicated curve or a sharp mountain shape, if you try to cut it manually, it will take a lot of time in addition to the required fabric area. A play piece is required to facilitate the half-cut 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 the cylindrical fabric in the longitudinal direction at fixed size intervals is a particularly important issue.

That is, since long fabrics are flexible and easily deformed, regardless of whether they are cylindrical or flat, it is extremely difficult to feed them to a fixed size, and furthermore, the fabric expands and contracts during feeding. Since then, it has become increasingly difficult to dispense it in a fixed amount.

Further, due to changes in the thickness of the fabric and different coefficients of friction, different speeds may occur in the fabric feeding, which is not desirable for fabric feeding devices.

If accurate and smooth feeding of each length of long fabric to the specified size and normalization of the feeding speed are not ensured, fabric processing in the next process, such as fabric cutting, will be disrupted, which will only lead to a decrease in fabric yield. This will lead to a decline in the quality of the underwear product.

The present invention was devised in view of the above-mentioned circumstances, and its structural features include: an apparatus for placing dough on a mold having a cut-out portion on the front edge and sending the dough forward; The formwork is provided with a conveying member that is long in the fabric feeding direction, racks are formed on the conveyance member at predetermined intervals in the longitudinal direction, a pinion rotating body is provided that engages with the racks, and the fabric is placed on the formwork. A pair of rotating bodies for feeding out the fabric are provided, and a continuously variable transmission is provided for driving the pinion rotating body and the rotating body for feeding the fabric in forward and reverse directions, and the formwork and the rotating body for feeding the fabric are synchronized with respect to the fabric feeding direction. In addition, a one-way clutch is provided in the transmission system of the dough feed-out rotary body for transmitting power only in the dough feed-out direction.

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. 7 and 8, a long tubular knitted fabric Q is attached to the guide roller 3 and the guide plate 2, and then to the core material 18.

When the fabric Q is a flat fabric, it is placed on the core material 18 and, in short, is attached to it.

At this time, the fabric Q is brought into a swollen state by the eccentric rollers 25, 26, 27 of the positioning and locking device 23 provided on the core material 18, as particularly illustrated in FIGS.
As shown in the figure, the left and right side edges 20a and 21a of the guide arms 20.21 of the core material 18 take a feeding preparation position that prevents the material Q from shifting in the width direction, and the feeding end of the material Q is moved to the formwork 6. While positioned at the cutting edge 6a of the fabric Q, the fabric presser body 29 is advanced toward the formwork 6 through the extension of the cylinder device 30, and presses the fabric Q.

Next, only the cutting blade 38 for half-cutting in the cutting device B is lowered, and the cutting edge 6a of the formwork 6 cooperates with the cutting blade 38 to cut the seventh cutter.
As shown in Figure 1, the area near the edge of the fabric is cut into an appropriate shape and marked with T.
is the cutting waste.

Thereafter, the tubular knitted fabric Q is moved to the right in the figure, and this movement is performed by raising and retracting the cutting blade 38 for half-cutting, and then starting the continuously variable transmission 15.

That is, if the transmission 15 is started in the normal rotation direction, the transmission body 16
The pinion rotating body 14 rotates in the feeding direction via the rotating body 14, and the rotating body 14 is engaged with the rack 7 of the conveying member 4 of the formwork 6, and the pair of left and right conveying members connected by the formwork 6. Since the wheels 5 provided at 4 can freely roll on the rails 1, the dough Q held between the dough presser body 29 and the formwork 6 is moved to the right.

Along with this forward movement of the conveyance 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, but this is done by the transmission body 17 and gears 12 and 13;
The core material 18 ensures that the fabric is fed at a fixed length while preventing the fabric from swinging laterally.

In addition, the coefficient of friction changes depending on the thickness and type of fabric Q.
Along with this, the pinion rotating body 14, the pair of rotating bodies 8, 8
is continuously variable by a continuously variable transmission 15 to appropriately correct the four feeds according to each fabric.

During this fabric feeding process, the cut waste T shown in FIG. 8 is pushed forward by the formwork 6 and collected into the collection box 40 by air suction.

Next, the conveyance body 42 in the relay conveyance device C moves to the left in the figure and is placed on the lower surface of the formwork 6 and waits, and the fabric Q is pressed by the fabric pressers 46 and 48 of the relay conveyance device C.
is pressed and the fabric presser body 29 provided on the formwork 6 is released through the contraction operation of the cylinder device 34, and then the formwork 6 is moved back.

That is, when the continuously variable transmission 15 is reversed, the wheels 5 of the conveying member 4 roll on the rails 1, and the formwork 6 returns to the retracted position on the lower surface of the core material 18.

This is done because the pinion rotating body 14 is engaged with the rack 7 of the conveying member 4, but in this case, the rotating body 8
A one-way clutch is built into the transmission system on the side, and the dough feed-out rotating body 8 is not rotated by the retreating movement of the formwork 6, so there is no shrinkage of the dough Q, and moreover, the dough Q is held in the presser body 4.
Since it is pressed at 8.48, it completely prevents shrinkage.

Furthermore, even if the formwork 6 moves back, the fabric does not sag because the conveying body 42 of the relay conveying device C supports the leading edge of the fabric.

Thereafter, the fabric presser body 29 provided in the formwork 6 advances against the formwork 6 through the extension of the cylinder device 34 and presses the fabric Q, and the large cutter 38 and the half cutter of the cutting device B 39 descends in one direction to obtain a sizing material R having a desired shape as shown in FIG. 8.

In addition, in FIG. 8, T1 is the waste at this time.

During the cutting operation of the cutting device B, the guide regulating device 36 restricts the horizontal vibration of the formwork 6.

Thereafter, the cutters 38 and 39 of the cutting device B and the fabric presser body 46 of the offshore conveyance device C are raised, and then the continuously variable transmission 15 is driven in the forward rotation direction, and the cylinder device (not shown) of the relay conveyance device C is moved upward. through which they move together to the right.

At this time, since the formwork 6 supports the fabric Q and the fabric Q is held by the fabric presser 29, the fabric Q is sent out by a fixed size in the same manner as described above.

The speed of the housing and formwork 6 is continuously variable through the engagement of the rack 7 and the pinion 14, and similarly, the dough feed rotary body 8 is synchronously driven in the feeding direction.

In the above specific example, when the formwork 6 moves forward, the conveyor 42 waits far from the sending end, and before the formwork 6 retreats, the conveyor 42 waits on the lower surface of the formwork 6. body 4
2 may be on standby in advance.

Further, after the relay conveyance device C moves onto the stacking device and releases the fabric presser 48, the relay conveyance device 42 is moved to the left in the figure until it reaches the bottom surface of the formwork 6, and the sizing fabric R is Transferred to stacking equipment.

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 49 of the stacking device rotates to the right and transfers to the final conveyance device E.

The present invention is as described above, and when the dough is placed on the formwork 6 and fed, the pinion rotating body is placed on the rack 7 provided on the formwork 6.
4 is driven under continuously variable speed, the speed of the rotating body 14 is continuously variable even when the thickness or type of dough changes, and the rotating body 14 is driven at a continuously variable speed to feed the dough placed on the formwork 6 while sandwiching it. The rotating bodies 8, 8 are provided with rotating bodies 8, 8, and the speed of the rotating bodies 8, 8 is continuously variable in the dough feeding direction in synchronization with the formwork 6, making it possible to feed the dough at a constant speed and in a fixed amount. It is very profitable.

In addition, since the transmission system of the dough feeding rotors 8, 8 is provided with a one-way clutch that transmits power only in the dough feeding direction, the dough is fed at a constant speed and a fixed amount, and the formwork 6 is retreated to prepare for the next feeding. When doing so, there is an advantage that there is no need to return the fabric that has been sent, and there is no shrinkage of the fabric.
