As shown in Fig. 9 and Fig. 13, step S103 is to put the unstitched socks 100 outside the outer tube 22, lower the outer tube 22 of the sock pressing unit 20, the first driving group 23, and the pressing ball 24 to Enter the unstitched sock 100 , make the unstitched sock 100 outside the outer tube 22 , and the pressure rollers 64 , 74 are located at the loose sock position and outside the unstitched sock 100 .

As shown in Fig. 9 and Fig. 14, step S104 is to press the unstitched sock 100, so that the pressure wheels 64, 74 are moved to the sock pressing position, so that they can be pressed against the outer tube 22 and press the unstitched sock 100 together. .

As shown in Fig. 9 and Fig. 15, step S105 is to push the unstitched sock 100 toward the top, make the pressure wheel 64 on the left side rotate counterclockwise, and the pressure wheel 74 on the right side rotate clockwise, and the The pre-sewn end 101 of the unsewn sock 100 is pushed toward the top end until the open end 102 is located outside the bottom opening 221 of the outer tube 22 .

As shown in Fig. 9 and Fig. 16, step S106 is to open the first chamber 25 of the sock pressing unit 20, make the pressing ball 24 drop away from the bottom opening 221 of the outer tube 22, and the first air pumping group 28 is opened to The first chamber 25 has a suction force.

As shown in Fig. 9 and Fig. 17, step S107 is to make the open end 102 of the unstitched sock 100 enter the first chamber 25, make the pressure wheel 64 on the left side rotate clockwise, and the pressure wheel 64 on the right side rotate clockwise. Turning the wheel 74 counterclockwise, the unstitched sock 100 can be pushed toward the bottom end, and the open end 102 can be sucked into the first chamber 25 in cooperation with the suction force in the first chamber 25 .

As shown in Figure 9 and Figure 18, step S108 is to complete the first turning over, when the open end 102 is located in the first chamber 25, the predetermined suture end 101 moves toward the bottom end and is located outside the bottom opening 221, The unstitched sock 100 has become the state where the inner surface 103 is outside, and then the outer cylinder 22 of the sock pressing unit 20, the first driving group 23, and the pressing ball 24 are raised, and the pressing wheels 64, 74 are lowered to the position At the top of the sleeve 83 , at this moment, the pressure ball 24 is in an open position relative to the bottom opening 221 .

As shown in Fig. 9, Fig. 19, Fig. 1 and Fig. 3, step S109 is to complete the stitching, first order the removing device 13 to transfer the predetermined stitching end 101 of the unsewn sock 100 to the turning unit 121, and then make the pressing The ball 24 rises to the closed position, and then one of the half-column coils 1011 of the predetermined sewing end 101 is turned over to the bottom of the other semi-column coil 1012 through the turning unit 121, and then the two stitches that are matched to each other are passed through a sewing needle 122. The two half-row stitches 1011, 1012 are stitched together to form a stitched end 101', and a stitched sock 100' is produced at the same time. At this time, the pressure ball 24 is located in the half-row stitches 1011, 1012.

As shown in Fig. 10 and Fig. 20, step S201 is to move the stitched sock 100' towards the bottom end, first make the outer tube 22 of the sock pressing unit 20, the first driving group 23, and the pressing ball 24 descend, and then Let the pressing ball 24 drop to the top of the sleeve 83, then the sewing end 101' is pressed by the pressing ball 24, and at the same time, the pressing wheels 64, 74 abut against the outside of the pressing ball 24 and press the sewn sock The opposite side of 100' is 104.

As shown in FIG. 10 and FIG. 21 , step S202 is to separate the stitched sock 100 ′ from the outer tube 22 , to rotate the pressure wheel 64 on the left side clockwise, and to rotate the pressure wheel 74 on the right side counterclockwise. Then the seamed sock 100 ′ can be pulled toward the bottom, so that the open end 102 can move toward the bottom and get out of the first chamber 25 .

As shown in Fig. 10 and Fig. 22, step S203 is to put the stitched sock 100' outside the sleeve 83, make the pressure wheel 64 on the left side continue to rotate clockwise, and the pressure wheel 74 on the right side Continue to rotate counterclockwise, and at the same time make the pressure rollers 64, 74 descend, and the stitched sock 100' can be quickly pulled toward the bottom end, and the stitched sock 100' can be placed outside the sleeve 83, At this moment, except the open end 102 of the seamed sock 100 ′ is still the reverse side 104 , other parts have become the front side 103 outside, and the pressing wheels 64 , 74 keep pressing the open end 102 .

As shown in Fig. 10 and Fig. 23, step S204 is to push the stitched sock 100' toward the top, so that the pressure rollers 64, 74 can be raised to quickly push the stitched sock 100' toward the top, so that the seam The end 101 ′ breaks away from the sleeve 83 .

As shown in Figure 10 and Figure 24, step S205 is to press the seamed sock 100', make the pressure ball 24 drop to the top of the sleeve 83 and cooperate with each other to press the seamed sock 100', and the seamed end 101 ' is sucked in the guide tube 91.

As shown in Figure 10 and Figure 25, step S206 is to turn over the open end 102 of the stitched sock 100', make the pressure wheel 64 on the left side rotate clockwise, and the pressure wheel 74 on the right side rotate counterclockwise , and the pressure rollers 64, 74 descend simultaneously, so that the open end 102 can move toward the bottom end and become the front side 103 outside.

As shown in Fig. 10 and Fig. 26, step S207 is to loosen the stitched sock 100', and make the pressing ball 24 rise to loosen the stitched sock 100'.

As shown in Fig. 10 and Fig. 27, step S208 is to remove the stitched socks 100', raise the pressure rollers 64, 74, cooperate with the guide tube 91 to generate suction force on the stitched end 101', and then Quickly push the seamed sock 100' toward the top, so that the open end 102 is disengaged from the sleeve 83, and finally the seamed sock 100' is sucked into the guide tube 91 and dropped into a collection box (not shown).

To sum up the above, the sock turning device and the sock turning method of the present invention have the following effects and advantages:

The present invention presses and pushes and pulls the unstitched socks 100 by the pressure wheels 64, 74, and only needs to use a small suction force to complete the turning over, and can improve the success rate of turning over to improve work efficiency. The stitched sock 100' can be automatically turned over and removed, which can improve the working efficiency of sock making.
