Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sock accumulating device, and more particularly to a sock collecting device that collects a predetermined number of inspected socks extracted from a sock inspection template of a sock inspection machine by a sock extraction device. The present invention relates to a method and device for accumulating socks by stacking them each time.

Before a sock can be put on the market as a product, it must be inspected. Inspection of socks is to check for unevenness that occurs when the socks are finished setting, or for poor sewing on the sock toe area, etc., and conventionally, socks are inspected using a single piece of sock that is rotatably erected by an appropriate means. One worker places the socks to be inspected one by one on the inspection template, rotates the template and inspects the socks on both sides of the template, distinguishes between defective and non-defective products, and picks out the non-defective products. For example, in preparation for the packaging of socks, a predetermined number of socks were stacked in bundles.

Since the process of conventional sock inspection work is largely dependent on the manual labor of workers, the degree of fatigue of the workers involved is high, and on the other hand, the work efficiency of the inspection is low.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a sock accumulating device for collecting inspected socks in which no defective parts are found in such socks inspection work into bundles after removing them from the inspection template. .

The sock accumulating device according to the present invention is characterized in that the socks pulled out from the template by the sock extracting device are conveyed horizontally in one direction by an appropriate conveyance member, and In front of
The transported socks are transferred in a direction perpendicular to the transport direction, and the socks are transferred from the transport member onto a receiving plate, and then the socks are placed one after another at a predetermined timing on a stacking plate located directly below the receiving plate. The transferred socks are guided and regulated on one side by a fixed guide member and allowed to fall, and are successively stacked and stacked on the stacking board. When a predetermined number of socks have been stacked, a carry-out member is positioned directly below the stacking board. The accumulated socks are allowed to fall while being guided and regulated on one side by a fixed guide member, and then the dropped accumulated socks are carried out of the system from the accumulation position by a carrying-out member. It's there.

direction) so that it can move forward and backward across the sock conveying surface of the conveyor belt 12.

Next, the sock receiving plate 40 horizontally disposed at the position where the socks H are transferred by the transfer plate 30 will be explained.

As shown in FIG. 3, a flat sock receiving plate 40 is disposed horizontally flush with or slightly below the sock conveying surface formed by the conveyor belt 12, and is placed on the side of the receiving plate 40 as appropriate. The tip of a piston rod 41a of an air cylinder 41 which is fixedly disposed horizontally is fixed by a means, and the receiving plate 40 is configured to be movable back and forth in the direction of arrow F in FIG. 3 by the operation of the air cylinder 41. ing.

As shown in FIG. 3, the receiving plate 40 has three parallel notched grooves 40 extending from the conveyor belt 12 side.
Notches a, 40b, and 40c are formed, and guide rods, which will be described later, are loosely inserted into the notch grooves 40a, 40b, and 40c, respectively.

Next, the sock accumulating member 50 provided directly below the receiving plate 40 will be described with reference to FIG. 3.

Immediately below the receiving plate 40, a stacking plate 51 is horizontally disposed with an appropriate spacing for stacking socks, and on the sides of the stacking plate 51, a horizontally fixed position is provided using an appropriate means. The tip of the piston rod 52a of the air cylinder 52 is fixed, and the actuation of the air cylinder 52 causes the stacking plate 51 to
is configured to be able to move forward and backward in the direction of arrow G in FIG.

A rectangular frame-shaped guide frame 53a is fixedly arranged between the receiving plate 40 and the collecting plate 51 with an appropriate distance between the receiving plate 40 and the collecting plate 51, respectively. Three guide rods 53b are provided above the outer surface of the side guide frame 53a.
53c and 53d are standing upright.

The guide rods 53b, 53c, and 53d fit into the cutout grooves 40a, 40b, and 40 of the receiving plate 40, as described above.
It is loosely inserted into c.

The guide frame 53a and guide rods 53b, 5

serves as a sock guide when the receiving plate 40 moves in the direction of the arrow F in FIG. Also, the guide frame 53a
The stacking plate 51 moves in the direction of arrow G in FIG. 3 to guide and regulate one side of a plurality of socks accumulated in a bundle so that they fall to a predetermined position on a carry-out member 60, which will be described next. It functions as a guide.

A carry-out member 60 is provided directly below the stacking plate 51 for carrying out the socks stacked in a bundle on the stacking plate 51 from the sock stacking position.

As shown in FIG. 3, the carrying-out member 60 is constructed by a conveyor belt 62 stretched around a pair of conveyor rollers 61a and 61b, and one of the conveyor rollers is driven by an appropriate drive source (not shown). By doing so, the bundled socks that have fallen onto the carrying-out member 60 are carried out to a predetermined position.

Next, the operation of the sock accumulating device having the above structure will be explained in relation to the sock inspection machine and the sock extraction device, including other embodiments.

First, an operator attaches socks H to the sock inspection template 1 of the sock inspection machine 2 shown in FIG. 1 at the first work station position shown in FIG.

In this installation work, the sock H, which was turned inside out during the sock toe linking work, is
As shown in Figure C, it is worn while being turned inside out. Of course, if the socks are turned inside out, they may be attached to the template 1 as they are.

Although a curved template 1 is shown in FIGS. 1 and 2, a flat template may also be used. A curved template has the advantage that it is easier to put on and remove the sock than a flat template.
(The following will be explained using a curved template as shown.)
By applying an appropriate color to the template 1, it is possible to easily inspect the socks H attached to the template 1.

The template 1 on which the socks H are attached as described above at the first work station in FIG. 1 reaches the second work station on the endless track in the state shown in FIG. Therefore, the worn socks H are inspected while rotating the template 1 as shown in FIG. 2D.

At the second work station position, defective products are pulled out from the template 1 by the worker as a result of the inspection, and non-defective products are removed from the second work station (sock removal position) while remaining attached to the template 1. Move sequentially to

First, inspected socks are continuously extracted from the template 1a (see FIG. 1) that has reached the third work station of the sock inspection machine 2 by a sock extraction device.

The template 1a that reaches the sock removal position is rotated by the operator during the sock inspection at the second work station, but is configured so that it can be fixed in place by a suitable locking member. After the inspection, the template is fixed with its curved surface facing the center of the sock inspection machine 2, as shown in FIG. 1, and the sock is removed from the template 1a in this state.

First, the air cylinder 22 of the sock removal auxiliary member 20 shown in FIG. 3 is activated to bring the presser 26, whose surface is coated with synthetic rubber, into contact with the template 1a from the state shown in FIG. 4A. It is brought into close contact with the sock attached to the template 1a and is slid upward along the curved surface of the template 1a to the state shown in FIG. 4B. At this time, the template 1a is simultaneously pressed against the circumferential surface formed by the conveyor belt 12.
As shown in FIG. 4B, the inspected socks H are attached to the template 1a by the running of the conveyor belt 12 and the sliding of the presser 26, and the toe part of the inspected socks H escapes from the template 1a and becomes the roller 11b. conveyor belt 12
It is inserted into the nip of the

Since the air cylinder 22 is urged toward the stopper 20 by the spring 25, the presser 26 can slide along the curved surface of the template 1a while constantly pressing the template 1a against the conveyor belt 12. I can do it.

When the toe portion of the sock is inserted into the nip portion of the sock removal member 10, the presser 26 of the sock removal auxiliary member 20 is returned to its original position as shown in FIG. 4C by the return movement of the air cylinder 22 and the action of the spring 25. At the same time, the template 1a also leaves the conveyor belt 12, but the inspected socks H are pulled out from the template 1a by being pinched by the conveyor belt 12 and the nip of the roller 11b, and are moved to the upper guide plate 17. The sock is then guided and conveyed on the sock conveying surface of the conveyor belt 12.

When the sock end of the sock H is detected by the sensor 16 on the sock conveying surface of the conveyor belt 12 and comes to rest on the conveyor belt 12 as shown in FIG. Therefore, the sock H is advanced in the direction of the arrow E in FIG. 3 from the solid line position to the chain line position, and the sock H is pushed out onto the sock receiving plate 40 while maintaining its flat shape, and delivered.

Next, by operating the air cylinder 41, the receiving plate 40 on which the socks H have been transferred is advanced in the direction of the arrow F in FIG. The sock accumulating member 50 falls to a predetermined position on the accumulating plate 51 of the sock accumulating member 50 located directly below the receiving plate 40 in a horizontal state while being guided and regulated by.

The transfer plate 30 transfers the socks H one by one to the sock receiving plate 40 and returns to the standby position shown by the solid line in FIG. 51 and return to the original position shown by the solid line in Figure 3.

By repeating the above operations, a plurality of socks H are stacked in a bundle on the stacking board 51 as shown in FIG. From this state, the stacking plate 51 is moved by the arrow G in FIG. 3 by the operation of the air cylinder 52.
The accumulated socks are guided and regulated on one side by the guide frame 53a and dropped to a predetermined position on the carry-out member 60, and the carried-out member 60 moves the accumulated socks in a bundle in a predetermined direction. It will be transported to After the stacking board 51 drops the bundled socks onto the carrying-out member 60, it returns to the position shown by the solid line in FIG. 3 and prepares for the next sock stacking operation.

Note that the guide frame 53a and the guide rods 53b, 53
A fixed guide member 53 consisting of c and 53d.
is integrally fixed to the frame (not shown) of the device, but this fixed guide member 53 is not limited to the configuration shown in FIG. Any device may be used as long as it guides and restricts the socks placed on each sock to be maintained at the placement position when moving in the directions of arrows F and G.

In FIG. 3, a carry-out member 60 is provided below the stacking plate 51 with a distance corresponding to the thickness of the socks stacked in a bundle, and guide plates 63a and 63b are fixedly arranged on both sides of the carry-out member 60. However, it goes without saying that the carrying-out member 60 can function similarly even if it is provided directly below the stacking plate 51. In this case, it is necessary to open the side of the guide frame 53a from which the bundled socks are taken out.

In the case where the above-mentioned separation is provided between the stacking board 51 and the carrying-out member 60 as shown in FIG. The socks accumulated in step 51 are temporarily transferred to the conveyor belt 62 of the carrying-out member 60.
After supplying the socks by dropping them onto the conveyor belt 62, the stacking board 51 is returned to its original position as shown by the solid line in FIG. By placing the bundled socks on top of the sock 51, the socks accumulated twice can be carried out at once in a bundle. At this time, naturally, the conveyor belt 62 of the carrying-out member 60 must be configured to run intermittently.

Next, another embodiment of the sock accumulating member 50 will be described.

First, FIG. 6A shows a pair of upper and lower stacking plates 70a and 70b provided below a sock receiving plate 40 at an appropriate interval, a receiving plate 40, and a fixed arrangement at the side end of each stacking plate. This is an integrated member composed of a fixed guide member 71.

This accumulating member first collects the socks H dropped from the sock receiving plate 40 and collects them on the upper accumulating plate 70a.
After stacking a predetermined number of sheets as shown in FIG. dropping and supplying a bundle of socks to a predetermined position on the accumulation board 70b;
Furthermore, the upper stacking plate 70a is returned to its original position as shown in FIG. 7D, and the socks are stacked again, and the stacked socks are first placed on the lower stacking plate 70b as shown in FIG. 6E. The bundle of socks is stacked on top of the bundled socks. Thereafter, the lower stacking plate 70b is moved as shown in FIG. 6F, and the stacked socks are dropped and supplied onto the carrying-out member 60 via the fixed guide member 71.

That is, if the socks H are dropped directly from the receiving plate 40 onto the stacking board 70b below, the socks will come apart, making it difficult to stack the socks in a bundle correctly at a predetermined position on the stacking board 70b. Then, the upper accumulating plate 70a receives and partially accumulates the socks, and by stacking the partially accumulated socks, a large number of socks are transferred to the lower accumulating plate 70b.
They can be stacked horizontally in a bundle.

Although the case where the above-mentioned stacking plates are configured as a pair of upper and lower stackers has been described, by increasing the number of stacking plates, a larger number of socks can be stacked in a bundle and fed onto the carrying-out member 60. can. For example, the lower stacking plate 70b of the stacking member shown in FIG. 6A.
As shown in FIG. 6E, stacking plates are provided at appropriate intervals below the stacking plate 70b to receive the socks accumulated on the stacking plate 70b as shown in FIG. 6E. , accumulation board 7
By supplying and placing the socks newly accumulated on 0b in the state shown in FIG. 6E on the bundled socks previously supplied on the new accumulation board, the socks shown in FIG. It is possible to accumulate twice the number of socks. In FIG. 6E, a case is shown in which five socks are accumulated on each of the accumulation plates 70a and 70b, but it is of course possible to accumulate two socks, for example. Since the spacing between the stacking plates 70a and 70b and the spacing between the receiving plate 40 and the stacking plate 70a are narrowed, the sock stacking operation performed by dropping the socks horizontally can be performed more reliably.

The fixed guide member 71 includes the guide frame 53a and the guide frame 5 previously explained with reference to FIG.
Guide rods 53b, 53c fixedly fixed to 3a,
53d integrally constitute the fixed guide member 53, the fixed guide member 71 in FIG.
40c and the pair of upper and lower stacking plates 70a, 70b can be integrally formed through appropriate notch grooves (not shown).

Next, as shown in FIG. 7A, an accumulation plate 72 is arranged horizontally below the sock receiving plate 40 with an appropriate interval (corresponding to at least the thickness of one sock). A fixed guide member 73 is fixedly disposed at the side end of the stacking plate 72 and extends from above the carrying-out member 60 to above the receiving plate 40 . Each time a sock H is dropped horizontally from the receiving plate 40, the accumulating plate 72 descends by the thickness of one sock, and as shown in FIG. 7B, a predetermined number of socks are stacked on the accumulating plate 72. Accumulate.

Thereafter, by moving the stacking plate 72 horizontally as shown in FIG. It is meant to be supplied as it falls.

Although the drive mechanism for the stacking plate 72 is not shown in the drawings, for example, an air cylinder is installed horizontally on the side of a sliding body screwed onto a vertical screw shaft, and the tip of the piston rod of the air cylinder is used to move the stacking plate 72. The stacking plate 72 is fixed to the side surface of the direction, and by rotating the screw shaft with an appropriate driving source and sliding the sliding body along an appropriate guide rod, the stacking plate 72 is reciprocally raised and lowered, and the air cylinder is operated. Therefore, the stacking plate 72 can be moved back and forth in the horizontal direction.

The template from which the inspected socks H have been removed is moved from the third work station position of the sock inspection machine 2 shown in FIG. 1 to the first work station position in preparation for the next sock inspection operation. The holding tool 26 of the sock removal assisting member 20 is momentarily activated to press the template against the conveyor belt 12 and to release the sock toe attached thereto from the template. This does not prevent the sock inspection machine 2 from continuously moving around on the endless track.

By repeating the above operations, the inspected socks attached to the template of the sock inspection machine 2 are automatically and continuously extracted from the template, and a predetermined number of socks are stacked in a bundle. It is.

According to the above-mentioned sock extraction and stacking device, the conventional work of manually pulling inspected socks from the template of a sock inspection machine and stacking a predetermined number of socks into bundles can now be done automatically. It can be carried out continuously, and one worker attaches the socks to the inspection template, inspects them, then distinguishes between good and defective socks, pulls them out from the template, and collects the good socks in a bundle. Compared to the conventional method, the efficiency of sock inspection work can be significantly improved, and worker fatigue can be reduced, allowing workers to concentrate on the sock inspection work, thereby reducing inspection errors. can be reduced.

The above description has been about the case where inspected socks are extracted from the sock inspection template of the sock inspection machine and accumulated in a bundle. The same procedure can be applied to the case where finished socks are removed from the template and collected.

According to the sock stacking device of the present invention, it is possible to automatically and continuously stack a predetermined number of inspected socks extracted from a sock inspection template and transport them to a predetermined position in the stacked state. By configuring the member accumulating plate in several stages or by configuring the accumulating plate so that it can be raised and lowered, the socks that are supplied by falling horizontally from the receiving plate can be correctly stacked and accumulated at a predetermined position on the accumulating plate, and are aligned. The socks that have been stacked in an orderly manner can be carried out to a predetermined position.
