Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on the method of
To provide a new means for accurately and easily peeling off sheets of fabric.

When sewing various types of fabrics, a work style is often used in which a large number of fabrics cut into the same shape are stacked together, and each layer is peeled off from the top and fed to the sewing process. In this case, it is known to mechanize and automate the feeding of each sheet in response to the automation of sewing. For this reason, compressed air or clothing has been used as a conventional means for automatically peeling off and taking out one piece of fabric from the uppermost surface of a stack of fabrics.

For example, Japanese Patent Publication No. 45-32796 discloses a method in which the uppermost layer of fabric is made to float by injecting air, then wound around a roller via a needle, and then transferred to the next process.

However, in the conventional method described above, the fabric is transferred to the next process by keeping the fabric wrapped around the roller and further rotating the roller in the winding direction. In this case, if the fabric falls off the roller during transfer to the next process, the layered state of the fabric group will be incomplete, and there will be a problem that the separation of the fabric, which should be done one by one, will not be reliable. There is.

The present invention solves the above-mentioned problems.
This product has been improved so that the automatic peeling of sheets can be performed accurately and easily.The feature is that when peeling the fabric one by one from the top layer of the laminated fabric group, the top layer of fabric is While blowing air, a clothing roll with clothing laid on the roll circumferential surface is lowered into contact with one end of the fabric, and the clothing roller is rotated in the normal direction under the pressure of the other end of the fabric, and the clothing roll is placed on one end of the fabric. is wound through the locking of the clothing, the same fabric is peeled off by raising the clothing roller, an intermediary plate is positioned below the top layer of fabric, and the top layer is reversed by reversing the clothing roller. The second layer of dough is dropped onto an intermediary plate, and the uppermost layer of dough is transferred to the next process side by the intermediary plate.

The present invention will be described in detail below with reference to the illustrated embodiments. In FIGS. 1 and 2, a fabric 1 having an appropriate knitting or weaving structure and cut into a desired shape is placed on a laminating table 2. Mounted and supported as a group. At this time, as illustrated in FIG.
A pinion 5, which can rotate forward and backward, is engaged with the pinion 5 at a fixed position, so that the pinion 5 is raised and lowered through forward and reverse rotation, and through sensing by a phototube or other sensing member 6, one of the top layer fabrics 1 is moved up and down. Each time a sheet is peeled off, the stacking table 2 is of a type that automatically rises by one sheet of fabric, and of course, the structure that can be raised and lowered is equally effective even in cases other than the illustrated example. Further, on one side of the stacking table 2, a presser member 7 is provided for pressing one end of the fabric 1 that is in contact with a clothing roller, which will be described later, and the other end opposite to the other end.
However, in the illustrated example, the piston rod 8 of the air cylinder 8
It is provided to be movable up and down by being supported by a, and is provided so as to press and support the other end side of the fabric 1 together with the laminated fabric group. In FIG. 1, the presser member 7
The other end of the dough 1 is extended from the outside to press it, but this is a pressing member shaped to cross the other end of the dough 1 in the form of a bridge, as illustrated in FIG. The same effect can be obtained by using a downward pressing type as the holding member 7a, and a structure other than the illustrated example may be used for the lifting and lowering structure of the holding members 7, 7a. Further, above the pressing member 7, there is an air nozzle 9 for injecting pressurized air slightly diagonally downward toward the upper surface of the uppermost layer of the fabric 1 and toward one end of the fabric 1.
A plurality of them are arranged as shown in the fourth figure. That is, by continuously jetting pressurized air from the same nozzle 9 toward one end of the fabric 1, a beat phenomenon is created on one side of the fabric, thereby causing the uppermost layer of fabric 1 to
This is to create a releasing action between the cloth 1 and the next second cloth 1, and a timer or the like is used to spray air continuously for a fixed period of time. In this case, the injection port of the nozzle 9 may be a slit-like opening having an appropriate width other than the pipe-like opening shown in the illustration.

In the present invention, above the air nozzle 9, a clothed roller 10 which can be raised and lowered as illustrated in FIGS. 1 and 4 is disposed. The same roller 10 is roll 10a
Clothes 10b are laid around the circumferential surface of the holding lever 13, one end of which is pivotally supported by a pin shaft 11 and is movable elastically by a tension spring 12. At the other end, the clothing roller 10 is supported on a shaft so that it can freely rotate in forward and reverse directions, and by attaching a constant torque reversible motor 14 to the roller 10, it can freely rotate in forward and reverse directions. Further, a piston rod 15a of a separate air cylinder 15 is slidably inserted into the middle of the holding lever 13 through a sliding hole 17, and an engaging head 16 of the rod 15a is inserted loosely.
is engaged with the lever 13, so that the clothing roll 10 can be moved up and down onto and away from the surface of the uppermost layer of fabric via the lever 13. That is, by moving the piston rod 15a of the air cylinder 15 downward from the lever-up state shown in FIG.
Through the weight of the clothed roller 10, the holding lever 13 rotates downward about the pin shaft 11, and the clothed roller 10 lowers while stretching the tension spring 12 downward due to its own weight, thereby removing the uppermost layer. The roller 10 comes into contact with the upper surface of the cloth 1, and at this time, the roller 10 is elastically supported in a state of contact with the weight of the roller 10 and the spring 12, and as a result, the clothing 10
b engages with one side of the uppermost layer of fabric, but prevents the needles of the clothing 10b from reaching the first side of the second layer of fabric, and the elasticity of the spring 12 allows the needles of the clothing 10b to
Make sure that 0b is only the first (top layer) fabric 1,
Moreover, a state in which they are engaged by lightly approaching and separating can be obtained. When the clothed roller 10 is raised, the lever 13 is pulled up and the clothed roller 10 is raised by the engaging movement of the engaging head 16 of the piston rod 15a of the air cylinder 15.
The structure shown on the right side in FIG. 1 is an example of a structure for taking out and transporting the uppermost layer of fabric 1 peeled off by the clothing roller 10 to the next process side. That is, Fig. 1, Fig. 5, Fig. 6, Fig. 7
In the figure, a conveyor 1 is connected in series with a stacking table 2.
8 is provided so as to be able to circulate freely via driving and driven rollers 19, 19, receives the fabric 1 held at one end by the clothing roller 10 on the carrier surface of the conveyor 18, and transfers it to the Conveyor 1
An intermediary plate 20 for transferring onto the conveyor 8 is arranged parallel to the conveyor 18 so as to be able to reciprocate. As shown in the figure, one end of the intermediary plate 20 is pivotally supported by a pin shaft 24 on a support rod 23 which is erected on a reciprocating block 22 which is supported on a guide rail 21 so as to be movable back and forth. By being connected to the piston rod 25a of the air cylinder 25 installed on the moving block 22,
Through the lifting and lowering of the piston rod 25a, the pin shaft 2

At the same time, an air injection part 27 having a slit-shaped injection port 27a extending in the width direction of the plate is provided, and a part of the plate 20 near the air injection part 27 is rotatable up and down via a rotary air cylinder 28 or the like. A fabric presser piece 29 is provided. Regarding the reciprocating movement of the reciprocating block 22, as shown in the figure,
Drives block 22, driven sprocket 30,3
By connecting it to a reciprocating chain 31 which is stretched between 0 and 31 so that it can freely rotate in forward and reverse directions, the reciprocating movement of the chain 31 is performed. for,
Limit switches A, B, and C as members for regulating the forward and backward movements and necessary operations are appropriately arranged as shown in the first figure.

In peeling off the top layer of fabric 1 from a group of laminated fabrics according to the present invention, in the case of the embodiment, the sequence shown in FIG. It will be carried out by.

First, in the state shown in FIG.
Pressurized air is injected from the air nozzle 9 through a timer or the like onto the surface for a certain period of time, and the uppermost layer of fabric 1 is beaten, thereby changing the fabric 1 and the second fabric 1 from a close state to a loose state. At the same time, the piston rod 15a of the air cylinder 15 is moved downward from the state shown in FIG. 1 as shown in FIG. The roller 10 is automatically held by the pin shaft 11 of the holding lever 13.
The roller 1 is lowered by rotating around the fulcrum.
0 is brought into contact with one surface of the uppermost layer of fabric in the floating state. At this time, prior to the lowering, the clothing roller 10 is rotated counterclockwise via the reversible motor 14, as shown in FIG. 3A.
At the same time, the presser member 7 is lowered by the air cylinder 8 to press and support the other end of the fabric 1 on the opposite side.

Since the clothing roller 10 descends due to its own weight, it descends against the tension spring 12, so as shown in FIG. The lowering of the clothing roller 10 is stopped in a state where the weight of the roller 10 and the lever 13 and the tension spring 12 are balanced, and the uppermost layer is It will come in contact with one side of the fabric. As a result, the clothing 10b on the same roller 10 rotates together with the rotation of the roller 10 and engages one side of the uppermost layer of fabric, but the needles of the clothing 10b reach the first side of the second layer of fabric. The fabric 1 of the top layer is brought into a state of light elastic contact and engagement to prevent the uppermost layer of fabric 1 from turning.
One end is engaged with the clothing 10b and stretched in the rotational direction of the arrow, and then wrapped around the same roller 10, and at this time, the tensile force of the fabric 1 and the constant torque of the reversible motor 14 are balanced. . Further, the leading edge 1a of the fabric 1 is in a bent state hanging from the roll circumferential surface as shown in the figure.

After wrapping only the uppermost layer of fabric 1 around the roller circumferential surface without the risk of the second fabric 1 being attached as described above, as shown in FIG. 3B, the air injection from the air nozzle 9 is stopped, The clothing roller 10, around which one end of the fabric 1 is wrapped, is raised to the old position by pulling up the piston rod 15a of the air cylinder 15 and simultaneously raising the holding lever 13 by the engaging head 16 of the rod 15a. Thus, the uppermost layer of fabric 1 is completely separated from the second fabric 1 side, except for the other end pressed by the presser member 7. At the same time, the intermediary plate 20, which is in the state shown in FIG. The tip side is advanced above the group of laminated fabrics 1 on the lamination table 2 in a horizontal position, and in this advanced position, the limit switch A is indicated, the air cylinder 25 of the block 22 is driven, and its piston rod is By retracting 25a, the intermediate plate 20 is tilted forward using the pin shaft 24 as a fulcrum. Next, as shown in FIG. 3C, the clothing roller 10 in the raised position is rotated counterclockwise via the reversible motor 14, and pressurized air is applied from the air nozzle 9 toward the top layer of fabric that has been peeled off. By spraying, the cloth 10b is rotated in the opposite direction and the cloth 1 is disengaged from the needle.
One end of the fabric 1 falls onto the inclined intermediary plate 20, and by the air jetted from the air nozzle 9 and the air jetted from the air injection part 27 at the front end of the plate 20, which is driven as the intermediary plate 20 advances, The wrinkles of the fallen fabric 1 are smoothed out. At this time, air nozzle 9 and air injection part 2
The air injection from 7 is performed for a certain period of time and then stopped. After the falling dough 1 is stretched by air, the dough holding piece 29 on the intermediary plate 20 is rotated downward as shown from the solid line to the dotted line in FIG. At the same time, the presser member 7 on the other end side is raised to release the other end side of the fabric 1. Next, as shown in FIG. 3D, the intermediate plate 20 in the inclined state is adjusted to a horizontal position by the air cylinder 25, and the reciprocating block 22, which is stopped at the limit switch A position, is moved to the limit switch via the reciprocating chain 31. This will cause it to retreat toward the B side. The uppermost layer of fabric 1 thus peeled off is held by the fabric presser piece 29 and transferred to the intermediary plate 2.
It will cross over onto the conveyor 18 together with 0. When the intermediary plate 20 is moved back, the reciprocating block 22 is sensed by the limit switch C disposed between the limit switch A and the limit switch B, and the fabric presser piece 29 is moved from the rotational prone position to the position shown in FIG. By standing up and rotating as shown and releasing the support for the fabric 1, the fabric 1 will completely fall onto the conveyor 18 as shown in FIG. That is, this intermediate plate 20
By setting the retraction speed of the intermediary plate 20 to be faster than the conveyance speed of the conveyor 18 in the same direction as the intermediary plate 20, one end of the reciprocating block 22 is moved back on the intermediary plate 20. As shown in FIG. 3, the dough 1 escapes due to the retreat speed of the plate 20 being faster than that of the conveyor 18, and completely falls onto the conveyor 18, and is carried out by the conveyor 18 to the next process. As a result, the reciprocating block 22 reaches the limit switch B position and stops at this position, and the intermediary plate 20 also stops at the same time, preparing for the next advance. On the other hand, on the stacking table 2 side, the peeling and removal of the top layer fabric 1 is completed, and the fabric 1 rises by one fabric through the sensing member 6, and the second fabric 1 takes over as the top layer position, and the air nozzle 9 is moved again. The peeling operation following the injection of pressurized air is repeated.

According to the present invention, by floating the uppermost layer of the laminated fabric group by jetting air and winding it with a clothing roll, it can be reliably peeled upward from the lower layer fabric group. Then, a mediating plate is positioned below the top layer of fabric that has been reliably peeled off,
Reversing the peeling roll ensures that the top layer of fabric falls onto the intermediary plate. This results in
The transfer of the uppermost layer of fabric to the next process by the intermediary plate is ensured, there is no error in transferring the fabric, and each piece of fabric can be reliably peeled one by one from the layered group of fabrics.
