Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for turning over a cylindrical sock fabric with a heel formed using a sock knitting machine so that the back knitted fabric of the sock fabric is exposed on the front side as a pre-step to the toe sewing process. .

When sock fabric is knitted using a conventional sock knitting machine, the welt part at the beginning of knitting hangs downward into the cylinder and is knitted sequentially from the heel to the toe. It appears and is not turned over.

To form a suture at the toe, it is necessary to turn the sock fabric inside out, so either turn it over manually or slightly push the tip of the sock fabric into the mouth of the suction tube and turn it inside out into the suction tube to cause suction. However, since all of this is done manually, it is inefficient and requires a lot of effort.

The present invention eliminates such drawbacks, and an embodiment thereof will be described in detail with reference to the drawings.A plurality of cams 3 are mounted on the outer peripheral edge of a pedestal 2 having a circular hole 1 in the center. A rotary plate 5 fixed radially and at equal intervals and having a circular hole 4 in the center is mounted rotatably, and a plurality of grooves 6 are provided radially and circularly in the center. A guide member 8 provided with a hole 7 is placed on the rotary plate 5 so that the rotary plate 5 is rotatable.

To prevent rotation of the rotary plate 5, circular grooves 5' and 5' are provided on the upper and lower surfaces of the rotary plate 5, respectively, and steel plates 9 are fitted into appropriate positions on the pedestal 2 and the guide member 8. By rolling the steel plate 9 along the circular concave grooves 5', 5', the pedestal 2 and the guide member 8 are fixed, and only the rotary plate 5 is made rotatable.

A large cylinder 11 having a thick diameter and having a vertical groove 10 connected to the groove 6 from the mouth part split by a predetermined length is inserted into the circular holes 1, 4, and 7. It fits into the communication hole formed in communication and is fixed to the pedestal 2.

A plurality of index rods 14 are bent into an L shape at one end, and have a locking protrusion 12 at the rising end thereof, and a cam follower 13 that contacts the cam 3 at the other end. 6
The pair of index rods 14 are slidably inserted into the index rods 14 so that they can move forward and backward in the centripetal direction by rotation of the rotary plate 5, and each locking protrusion 12 of the index rods 14 is always pulled in the centripetal direction and maintained in a state of contact. 14 are connected by a tension spring 15.

A small cylinder 18 has a suction pipe 16 connected to the lower end of the large cylinder 11 and has a diameter that allows the sock fabric 17 to be inserted loosely therein.
is loosely inserted into the upper opening of the large cylinder 11 so that it can be raised and lowered freely.

As a means for raising and lowering the small cylinder 18, a mechanism is used in which a projection 19 provided at an appropriate position on the outer wall of the small cylinder 18 is engaged with a worm 20.

Since the present invention is constructed in this way, the sock fabric 17 is loosely inserted into the small cylinder 18 with the rubber knitted welt part facing down, and the locking protrusions 12 and 12 are in contact with each other while grasping the toe part.
... is covered with the welt portion, and then the rotary plate 5 is rotated by a predetermined angle and fixed, and each index rod 14 is guided outward by the guide member 8 and advances, and each index rod 14 is locked. The protrusions 12 expand to expand and grip the welt portion of the sock fabric 17.

By gradually lowering the small cylinder 18 of the welt part in this extended gripping state, the front knitted fabric of the sock fabric 17 is pressed by the lower edge of the small cylinder 18 and pushed down so as to cover the outer peripheral wall of the small cylinder 18, and the sock When the front and back sides of the knitted fabric 17 have been reversed, the worm 20 is reversed to raise the small cylinder 1.8 and return it to its original position, and then the rotary plate 5 is rotated by a predetermined angle to rotate the index rod 14... When the sock fabric 17 is retracted and returned to its original position, the grip of the welt part by the locking protrusion 12 is released, and the turned-over sock fabric 17 is moved to the suction pipe 1.
It is conveyed by air suction from 6.

As described above, the device of the present invention is robust and durable, and is a useful invention that operates reliably.
