Abstract

PURPOSE:To prevent wrinkles or slacks of a cloth material and conserve labor by making the shift amplitude of a bucket larger than the maximum shake-off width above a mounting element, temporarily stopping the bucket at the maximum shift positions on the right and left, or slowing the shift speed directly before reaching these positions. CONSTITUTION:A bucket 15 at the lower end of swing arm 14 is swung to the right and left via the arms 14 by the rotation of a crank 16, a clutch brake 18 is activated by signals outputted when lugs 19 face a sensor at the maximum shift position of the arm 14 on the right and left, thus the bucket 15 is temporarily stopped at the maximum shift positions. A cloth material 22 fed into the bucket 15 by a feed roll 21 at a constant speed is slacked in a U-shape and is mounted on a saddel-type mounting element 25 by hitting it from the lateral direction, thereby wrinkles or slacks caused by the contact friction in the up-and-down direction are prevented from occuring.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for shaking off a fabric.

Generally, to shake off a fabric, a swinging arm 2 is attached and fixed to a frame 1, a packet 3 is provided at the tip of the swinging arm 2, and the swinging arm 2 is moved as shown in FIG. The swing arm 2 is connected to a crank 5 by a drive arm 4 and rotated by a motor 6 to swing the swing arm 2 from side to side about its fulcrum 7, thereby allowing the fabric article to be fed by the feed roll 8. 9 is shaken out onto the cloth truck LO and folded. In Figure 1, 1-
1 is a guide frame, and 12 is a motor that rotationally drives the feed roll 8. In this way, in the conventional fabric object shaking-off device that takes off the fabric object 9 and folds it, the fabric area ratio IO
A crease is left on the folded part of the fabric object 9 that is shaken off inside. Therefore, when something like a raised fabric is shaken off and folded as the fabric article 9, the hair of the raised fabric may be broken at the folded part, leaving a clear crease, which will be used in subsequent steps. But since it cannot be fixed,
This resulted in a significant reduction in product value. Therefore, when shaking off the fabric material 9, which has a fluffy surface like a raised fabric and has a large coefficient of friction, and a smoother back surface, it is possible to shake it off by placing it in a saddle shape instead of having a fabric area ratio of 10. Using a tool, the packet 3 is swung across the saddle-shaped mounting device, and thereby the fabric article 9 is shaken off from the packet 3 so as to be distributed left and right onto the saddle-shaped mounting device. It has been considered and is being implemented to sequentially load the vehicles. In this case, the fabric object 9 that is newly shaken off from the packet 3
The (raised fabric) is placed on the saddle-shaped mounting device from side to side, and runs downward while contacting the surface of the fabric article 9 hanging down from the top of the saddle-shaped mounting device. Then, by reversing the packet 3, it is folded back at the lower end and now runs upward while contacting the surface of the part that was previously shaken off. At this time, the surface of the fabric object 9 placed on the saddle-shaped mounting device and hanging down is the raised surface, and the surface of the fabric object 9 that is newly shaken off is in contact with the raised surface. When the surface is a raised surface, the fabric material 9 that is newly shaken off does not run smoothly downward due to frictional resistance, resulting in wrinkles and sagging. In addition, when the opposing surfaces of the part of the newly shaken-off fabric 9 that runs upward from the folded part at the lower end and the part that previously ran downward are raised surfaces, due to frictional resistance, The upward running force of the upward running section pulls up the part that ran downward first, resulting in wrinkles and sagging. Therefore, in order to avoid such problems, one worker is always present and uses a stick to guide the fabric items that are shaken off from the packets so that the fabric items that are placed from the packets do not wrinkle or sag. However, it is extremely inefficient to have one worker guide the fabric items that are shaken out of the packet.

The present invention was developed in view of the above circumstances, and it is possible to transport a long fabric article with different coefficients of friction on the front and back sides at a constant speed, and move it from the packet onto a saddle-shaped mounting device by swinging or horizontal reciprocating motion of the packet. A method for shaking off fabric articles sequentially placed on a saddle-shaped mounting device so as to distribute them left and right, the method of shaking off fabric objects sequentially on a saddle-shaped mounting device, in which the movement amplitude of the packet is distributed to the left and right of the fabric objects placed on the saddle-shaped mounting device. The maximum distribution amount, including the thickness of the upper part of the mounting device, is set to be larger than the thickness, and the bucket 1- is temporarily stopped at the left and right maximum movement position, or the movement speed is slowed just before reaching the maximum movement position. By doing so
, a fabric characterized in that the fabric newly shaken off from the packet gradually forms a U-shape on the side of the fabric that has already been placed on the saddle-shaped mounting device. The first gist is a method for shaking off objects, and the device for realizing this includes a swinging arm that swings left and right around a fulcrum, a drive source that drives this swinging arm, and the tip of the swinging arm. A packet for shaking off fabric objects provided in the packet, a constant speed feeding mechanism for continuously feeding fabric objects into this packet at a constant speed, and a mechanism for distributing the fabric objects shaken off from the packet to the left and right. Equipped with a saddle-shaped mounting device to place the packet in the same state and a swing arm temporary stop mechanism, the movement amplitude of the packet can be adjusted to
The distribution amount on the saddle-shaped mounting device is set so that the maximum distribution amount including the thickness of the upper part of the mounting device is larger than the thickness of the fabric to be placed, and the above-mentioned shaking is performed at the maximum movement position of the packet. The second aspect is a fabric shake-off device in which a movable arm temporary stop mechanism operates to temporarily stop a packet at that position.

That is, the present invention increases the moving amplitude of packets,
In addition, in order to temporarily stop the packet at the left and right maximum movement position or to slow down its movement speed, the fabric object newly shaken off from the packet is already placed on the saddle-shaped mounting device. They gradually form a U-shape on the sides of the fabric that is currently being shaken off and overlap from the lateral direction. Therefore, the fabric that is newly shaken off does not wrinkle or sag. To be more specific, the present invention allows a newly shaken-off fabric object to be dropped from top to bottom in contact with the outer surface of an already placed fabric object, and then is dropped at the lower end. Rather than inverting and pulling upwards, the newly shaken-off fabric object is stacked on top of the already placed fabric object from the side, so that the newly shaken-off fabric object and No contact friction occurs between the fabric objects already placed. Therefore, even if the raised surfaces with a large friction coefficient come into contact with each other, wrinkles and sagging will occur due to the contact friction. That's why.

Next, the present invention will be explained in detail based on examples.

FIG. 2 is a perspective view of one embodiment of the invention.

In the figure, 13 is a frame, and this frame 13
The swing arm 14 is marked with a mounting number.

A packet 15 is provided at the lower end of this swing arm 14. Reference numeral 16 denotes a crank, and the crank 16 and the swing arm 14 are connected by a drive arm 17 so that the swing arm 14 swings left and right as the crank 16 rotates. Reference numeral 18 denotes a clutch brake that transmits driving force from a motor (not shown) to the crank 16 through a belt to rotate the crank 16. The crank 16 is provided with a pair of protrusions 19 as shown, and the protrusions 19 face the sensor 2o at the maximum left and right movement position of the swing arm 14. The sensor 2o outputs a signal at the time of this encounter, operates the clutch brake 18, temporarily stops the crank 16, and thereby temporarily stops the packet 15 at the maximum movement position. 21 is a feed roll;
It is rotationally driven by a motor (not shown) and feeds the fabric 22 into the packet 15 at a constant speed as indicated by the arrow. 2
3 is a rotating shaft of the crank 16, 24 is a guide roll that acts as a guide for the fabric object 22, and 25 is a saddle-shaped mounting device on which the fabric object 22 shaken off from the packet 15 is placed horizontally. . A string 26 hangs down from the top of the packet 15 and has a pressing rod 27 at its lower end, thereby preventing the fabric object 22 from slipping off. Bucket above) 15
The traveling vehicle 29 mounted on the fixed frame 28 (FIG. 3) on the side is placed on the lower side of the guide frame 30 having a horizontal U-shaped cross section, and the traveling vehicle 29 is moved by the swinging of the swinging arm 14. By running along the lower side of the guide frame 30, it moves left and right. In this case, the total weight of the packet 15 is supported by the lower side of the guide frame 30 via the traveling vehicle 29.゛Then, the swing arm 14 is
As shown in the figure, it passes through the inside of the telescopic cylinder 31 provided on the side of the packet 15, and when swinging from side to side, the telescopic cylinder 31
1 is moved up and down along the swing arm 14 by the action of the linear ball bearing 32, and the packet 15 is smoothly moved left and right. What is noteworthy is the fifth
As shown in the figure, the amplitude of movement of this packet 15 is the maximum distribution of the fabric object 22 placed on the saddle-shaped mounting device 25, including the thickness of the mounting device 25, which is greater than the thickness S1. The maximum moving position of packet 15 (
The vehicle is designed to temporarily stop at the position shown in the figure.

As described above, according to this device, the packet 15 temporarily stops at the maximum movement position, so that, as shown in FIG. Then, it becomes the state shown by the two-dot chain line, and finally the state shown by the solid line. In this case, as the fabric object 22 hangs down, the portion of the fabric object 22 indicated by point a moves to the right side as shown by the arrow, and the portion of the fabric object 22 indicated by the dotted chain line point a moves to the right side as shown by the arrow, and the portion of the fabric object 22 that is indicated by the dotted chain line point a moves to the right side as the fabric object 22 hangs down. Thing 2
It comes into contact with 2 from the side. Similarly, the portion indicated by the dotted double-dashed line and the portion indicated by the solid line point C come to abut from the lateral direction on the fabric article 22 already placed. Therefore, the surface including these abutting points a, b, and c is a raised surface, and 1. Even if the surface of the fabric object 22 placed on the saddle-shaped mounting device 25 is a raised surface, points a,
b.

The surface containing C only comes into contact with the surface of the fabric object 22 placed above from the lateral direction, and no vertical friction occurs as in the conventional case, so wrinkles and sagging due to vertical contact friction occur. does not occur. That is, according to the conventional device,
As the newly shaken-off fabric hangs down while coming into contact with the fabric placed on the saddle-shaped mounting device, large contact friction occurs, causing wrinkles in the newly shaken-off fabric. This will cause sagging. However, according to this device, the newly shaken-off fabric object 22 comes into contact with and overlaps the fabric object 22 already placed on the saddle-shaped mounting device 25 from the lateral direction. Almost no contact friction occurs. Therefore, wrinkles and sagging due to contact friction do not occur. and,
As shown in the figure, the newly shaken-off fabric objects 22 are gradually shaken off in a U-shape, so that the newly shaken-off fabric objects 22 do not come into contact with each other. Therefore, even when the opposing U-shaped surfaces of the newly shaken-off fabric object 22 are raised surfaces and have a large friction coefficient, contact friction does not occur, so that the friction is caused by contact friction. No wrinkles or sagging. In addition, since the pressing rod 27 at the tip of the string 26 attached to the packet 15 presses one side of the upper part of the fabric object 22 placed on the mounting tool 25, it overlaps with the opposite side. The overlapping surface of the fabric object 22 (newly shaken off) and the fabric object 2 facing that surface
2 (already placed) is a smooth surface, so that even if the newly overlapping fabric object 22 tries to slide downward due to its own weight, it will be prevented from slipping, and the newly overlapping fabric object 22 will be accurately placed. It starts to overlap.

In particular, in this device, it is preferable to set the transition speed, movement distance (stroke), and pause time of the packet 15 as follows.

In other words, the packet transfer speed V1 is ■!, where the cloth speed is ■! It is preferable to set ≧V. In other words, the transition speed 1 of the packet 15 is determined by the cloth feeding speed V (m/5ee
), the fabric object 22 that is shaken off from the packet 15 is placed on the saddle-shaped mounting device 25 when the bucket) 15 crosses the saddle-shaped mounting device 25. This prevents wrinkles from forming at the top of the inverted U-shape of the fabric 22 and its vicinity. In addition, the movement ratio %il (stroke) S (FIG. 4(b)) of the packet 15 is determined by the amount of the fabric article 22 placed on the saddle-shaped placement device 25.
It is desirable that the maximum distribution amount including the thickness of the upper part of No. 5 is set as follows for the thickness S1.

S>31+0.4m In other words, by setting like this, packet 1
The fabric objects 22 that are shaken off from 5 gradually come to form a U-shape, and as the value becomes smaller than this, the fabric objects 22 that are newly shaken off tend to come into contact with each other. Undesirable. Further, by setting the packet suspension time T1 to , the newly shaken-off fabric object 22 can form a proper U-shape.

Here, L indicates the length, which is not shown in FIG. 5(a), and S and Sl are as described above. Furthermore, if this is arranged in a U-shaped length, the movement of the pin 15 is as shown in Fig. 5(b).

In the above embodiment, the packet 15 is swung by the oscillating mechanism, but it may be reciprocated by a horizontal reciprocating mechanism. Further, a limit switch may be provided in place of the sensor 20, and the bucket I-15 may be stopped for a certain period of time after passing the limit switch.

In the present invention, since the fabric object is shaken off as described above, the fabric object can be placed on the saddle-shaped mounting tool from side to side without wrinkles or sagging. therefore,
This eliminates the need for the worker to guide the fabric items that are shaken out of the packet, which has been done up until now, resulting in labor savings.
