Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for grasping bundled socks when the socks are picked up and bundled by a sock extraction device from a chuck member and transported to the next process position for processing. It is related to.

Conventional Technology Conventionally, in a sock finishing machine, a group of heat-set socks is extracted from a foot mold, bundled, grabbed, and transferred to the next process position, as disclosed in Japanese Patent Application Laid-Open No. 1986-
No. 63064 and JP-A-56-123456 are known.

These techniques involve grasping the toe portion of a group of socks using the chuck of a sock extraction device, pulling out the socks by lifting the chuck, and pulling the rolls from both sides of the group of socks to form a bundle of pulled socks. to force Then, the roughly central part of the hanging socks in a bundle is sorted out, and the socks are gripped vertically with two sets of upper and lower nipping plates, and after the chuck is released, the roll is moved and the socks are separated. While adjusting the disturbance and returning the roll to its original position,
The sandwich plate that grips the sock vertically is moved horizontally from the position where it grips the sock to the next process position outside the sock extraction device, releases the grip on the sock, and places the sock on the next process position cradle. The structure is such that the sandwich plates are replaced in a bundle and then the sandwich plates are returned to their original positions.

Problems to be Solved by the Invention However, the conventional technology has the following problems.

In the conventional technique, as shown in FIG. 12, the sock 1 is gripped by dividing the roughly central part of the bundled socks using two sets of sandwiching plates 30a, 30a with a predetermined interval between them. However, when a bundle of socks is pinched and held by a sandwich plate, the pinched state of the socks is the first.
Since the sock is pinched from both fulcrums a and b shown in Figure 3, the pinching pressure of the sock acts from points c and d, so the bundled socks bulge on the front side.
The front part is concave and uneven. Furthermore, when the socks are completely gripped, if the gripping interval of the sandwich plates (dimension e shown in Fig. 13) is not appropriate compared to the thickness of the bundled socks, the gripping state of the socks may be too strong or Therefore, if it is too weak, the sock will fall off from the sandwich plates 30a, and if it is too strong, the sock will be forced into contact with the sandwich plate, causing the finished sock to partially fall off. The texture of the socks is damaged due to excessive pressure, which poses a quality problem.

In order to prevent this, it is possible to adjust the gripping interval of the sandwich plate each time according to the thickness of the bundled socks, but it is also a hassle to adjust it every time the type or thickness of the socks changes. Furthermore, even with this method, the unevenness of the gripping state of the socks cannot be completely resolved, and an extra work remains to be done in the subsequent process, so an improvement measure is desperately needed.

The present invention provides a method for receiving socks pulled into a bundle by a sock extractor from a chuck member of the sock extractor and transferring them to the next process position. Japanese Patent Application No. 56-63064) and Japanese Patent Application No. 55-25742 (Japanese Patent Application

Next, its effect will be explained.

When the sock foot groups finished on the track 4 in the sock finishing machine are conveyed in a collected state to the sock removal section position, stopped and positioned, the sock lifting device B is moved as shown in FIGS. 1 and 2. The grip plate 16 is inserted into the lower position between each last, grasps each sock opening, moves up along the last 2, and tucks up the sock 1 onto the last 2.

On the other hand, the chuck plate 1 of the sock extraction device E
7 is lowered in accordance with the rise of the grip plate 16, and when the grip plate corrects the inclination of the tops of each foot shape and makes them equally spaced, the chuck plate 17 is inserted between the tops of each foot shape. Then, the toe part 7 and heel part 8 of the sock are grasped together with the last 2, and then the chuck plate 17 is raised upward and in front of the toe of the last 2, and the sock 1 is pulled out from the last 2 all at once. As shown by the two-dot chain line in Figure 2, it is suspended above the top of the foot.

At this time, the rolls 18 of the gathering roll member D are located below the chuck plate 17 and gather the rolls 18, 18 together from both sides of the group of socks 1 suspended, as shown in FIG. 11a. After bunching them toward the center, the air cylinder 35 of the sandwich plate rotation member J shown in FIG. 6 is operated to extend the piston rod and rotate the sandwich shaft 32, and the two dotted lines in FIG. As shown in , two sets of sandwich plates 30, 30 and a support rod 41 are rotated about a sandwich shaft 32 as a fulcrum. Then, the two sets of sandwich plates 3
0 and 30 are placed parallel to each other at appropriate intervals on both sides of the socks 1 which have been extracted and bundled by the sock extraction device E, as shown by the two-dot chain lines in FIGS. 11b and 10. .

Next, the rotary actuator 44 of the sandwich plate separating member K shown in FIG. 5 is operated to move the sandwich plates 30, 3.
0 close to each other and vertically grip the substantially center part and lower end of the bundled socks 1, and the chuck member C.
The chuck plate 17 releases its grip on the sock 1, and the pinch plate 30 receives the sock 1 from the chuck plate 17 (FIG. 11c). At this time, the support rod 41 is located on the side where the bundled socks 1 are turned horizontally.

Next, after moving the roll 18 in one direction to straighten out the disordered socks 1 in the bundle (FIG. 11d),
While the sandwich plate 30 is being lowered by the sock transfer processing device G and transferred to the outside of the sock extraction device E, the vertical grip of the sock by the sandwich plate is changed to the horizontal direction, and the air cylinder 40 of the sock support member M is activated. The support rod 41 is moved toward the toe of the sock to support the bundled sock 1 from below (FIG. 11e).

Next, when the next process position, the pedestal 10 (in this embodiment, the pedestal is used as a conveyor) is reached (Fig. 11f), the air cylinder 35 shown in Fig. 6 is operated in reverse to remove the sandwich plate 30 and the support rod. 41, and as shown in Fig. 11g, the bundled socks 1 are placed on the pedestal 10 in a well-balanced manner, and after that, the sandwich plate 30 and the support rod 41 rise and return to their original positions to stand by. One step is completed.

Effects of the Invention Since the present invention is configured as described above, the socks pulled out by the sock extraction device and made into a bundle can be held in parallel by being held in a parallel state.
It can respond to changes in the thickness of bundled socks, and
Since bundles of socks can be gripped with appropriate and uniform pressure, the extra man-hours required to adjust the spacing between the sandwich plates and to even out misaligned socks in the post-process are eliminated, resulting in labor savings and quality improvements. We can expect improvement.
