The pulleys 57a and 57b, the cam plates 58 and 59, the rods 60 and 61, 62 and 63, the cranks 64 and 65, and the pivot plates 66 and 67 are supported by 68).

On the other hand, one side of the transfer table 11 is coupled to the repair guide 69 for supplying again the sock (S) sewing is poor, the repair guide 69 is formed in a semi-circular arc inside The socks S are supplied to the inner side of the first transfer chains 12a and 12b and the second transfer chains 16a and 16b to be sewn in the cutting unit 30 and the sewing unit 40 and 41. This will be done.

Reference numeral 70 in the figure represents the expectation.

Socks sewing device according to the present invention configured as described above when the worker to supply the socks (S) to sew into the inlet 15, the transfer is made through the transfer unit 10 and the socks to be sewn in the cutting unit 30 At the same time as cutting the upper end of the (S) is sewn in the first and second sewing parts 40, 41 are made.

That is, the socks S supplied into the inlet part 15 are transported by the first transmission chain 25 by the rotational force according to the driving of the chain transfer motor 21, and the operation of the first transmission chain 25 is performed. As the rotary sprockets 23 and 24 rotate, the second and third transmission chains 26 and 27 wound thereon transmit the rotational force to the sprockets 14b and 18b, and the sprocket 14b. The sprockets 13b and 17b meshed with the rotation of the blade 18b rotate to drive the second transfer chains 16a and 16b.

At the same time, the sprocket 18a engaged with the sprocket 14b is rotated, and the sprocket 17a engaged with the sprocket is rotated so that the first transfer chains 12a and 12b rotate to transfer the socks S. will be.

Meanwhile, the socks S passing through the first transfer chains 12a and 12b flow into the cutting unit 30 through the second transfer chains 16a and 16b and flow into the cutting unit 30. The sock S is cut by the sewing unit by the forward operation of the cutting blade 31.

When the cutting force 30 is transmitted to the rotating shaft 53 through the belt 51 according to the driving of the drive motor 51, the rotating force is forward, backward from the rod 56 through the cam 55 again By being transmitted to the operation is to cut the upper end of the sock (S) supplied by cutting edge 31 is advanced.

Subsequently, the socks S transferred according to the operations of the second transfer chains 16a and 16b are made to be sewn in the sewing units 40 and 41.

That is, the rotational force according to the driving of the drive motor 51 is transmitted to the rotation shaft 53 through the belt 52, and this rotational force is again pulleys 57a and 57b and the cam plate through the belts 52a and 52b. Crank 64 through rods 60, 61, 62, 63 coupled to the pulleys 57a, 57b and cam plates 58, 59. When the transfer to the 65 and the rotating plate 66, 67, the longitudinal needle 43 and the cross needle 42 is to cross each other to sew the socks (S).

At this time, the longitudinal needle 43 and the cross needle 42 is sewing while repeatedly crossing each other by the operation of the rods 60, 61, 62, 63 to move forward and backward in the opposite direction.

The socks S sewn by the sewing units 40 and 41 are transferred by the operation of the second transfer chains 16a and 16b to complete sewing.

On the other hand, if the sewing state is bad in the sewing unit 40, 41, the worker puts the bad socks (S) back into the repair guide 69 so that the sewing is made in the sewing unit 40 (41). Done.

That is, the socks S introduced into the repair guide 69 are cut by the sewing parts 40 and 41 after the upper part is cut by the cutting blade 31 of the cutting part 30 and repaired. This makes it possible to reduce the defective rate accordingly.

As described above, according to the present invention, the transfer and sewing are performed according to the operation of different driving motors, so that the structure is simple and noise is minimized. It has various effects, such as minimizing the defective rate.
