Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for dividing a sock fabric continuously knitted by a double cylinder sock knitting machine, and for taking out a back knitted fabric by turning it over to the front side.

The double-cylinder sock knitting machine (Ripunitsuta) has an upper cylinder and a lower cylinder installed opposite each other, and double-ended needles can be freely transferred to the upper and lower cylinders. By pulling down the sock fabric with a take-up roll installed below the lower cylinder, the sock fabric is pulled down to prevent back stitches from overlapping and to make the knitted fabric uniform. It is necessary to remove the knitting yarn from the needle at each stitch and separate the socks one leg at a time using air suction, or to remove the long sock fabric from the knitting machine, insert scissors into the cutting position, and remove the threads to separate each leg one at a time. However, according to the former method of dividing the sock fabric, even if the sock fabric has a very short size at the beginning of knitting, even if it is suctioned with air, there is little pulling effect, and problems such as damage to the needle or slider due to the removal of the knitting yarn are likely to occur. In addition, the knitted fabric may be damaged and lose its texture, and the latter parting work is simple and requires patience, and if the scissors are inserted in the wrong position, it will result in defective products. There is a risk of contamination when taking out the sock fabric from the tank.

In addition, a device is proposed that sprays hot air or water on the sock fabric that has been pulled down and hanging down below the take-up roll device to separate it from the heat-soluble or water-soluble knitting yarn portion that has been knitted into the knitted fabric in advance. However, since the sock fabric divided by this device has not been turned over, it requires a tow stitching step and an additional step of turning the front and back sides of the knitted fabric.

In a device that takes out sock fabric by suctioning air in a suction pipe, the sock fabric forms a lump in the recovery tank, and it is necessary to align the sock fabric in preparation for the toe-sewing process.

The present invention has been provided in view of the above circumstances, and an embodiment thereof will be described in detail with reference to the drawings.The bearing is provided with plates 2, 2 facing each other at one end of the bed 1, covered with sock fabric 18, and moved.

Since the present invention is constructed in this manner, the continuously knitted sock fabric 18 is placed on the winding roll 4 from the insertion opening of the tube body 3.
, 4', the sock fabric 18 is fed to the cutting device 20 while being pinched by the bells N7, 17 and the tube body 3.

At this time, the phototube 19 detects the location of the sock fabric 18 where the heat-soluble or water-soluble yarns to be cut are knitted, measures the timing at which the cut location reaches the cutting device 20, and sends a delay signal to cut the sock fabric. The movement of 18 is temporarily stopped, and hot air or water is injected from the nozzle 2σ to melt and cut the chain yarn, separating each leg one by one.

The divided sock fabric 18 is sandwiched between the take-up rolls 34, 34' while being pinched by the bells) 25, 25 and the tube body 3, and then held between the tube bodies 35 and the bells) 46, 46. 35, and when the tip of the sock fabric 18 comes into contact with the limit switch 67, the belt 46° 460 movement first stops, and then the torque motor 38 operates to retract the advancing/retracting rod 38' and retracting the tubular body 35. When a space is formed between the abutting portion 3da and the end surface of the tube body 3, the belt 46° 46 is reversed by the transmission of the delay signal, so that the base end of the sock fabric 18 slightly covers the abutting portion 35'.

At this time, the blower 55 operates to suck the air in the suction pipe 36, so that the sock fabric 18 is sucked into the suction pipe 36 from the abutting portion 35' while turning over the front and back, and reaches the storage chamber 54.

At this time, the gripping device 64 moves forward, and the movable claw 63 and the fixed claw 6
3 reaches into the storage chamber 54, catches the lump-like sock fabric 18 in the storage chamber 54, and takes it out while pulling it out by retracting the gripping device 64.

When the sock fabric 18 covering the tube body 35 is sucked, the torque motor 38 becomes inactive and the tension springs 41, 4
The tube body 35 is pulled back to its original position by the tensile force of 1, and the abutting portion 35' abuts against the end surface of the tube body 3, so that the sock fabric 18 that is sent over the tube body 3 can be transferred to the tube body 35. Prepare accordingly.
