In the figure, 20 is a switch, 26 is a relay, 27
Is a timer, 30 is a speed controller for adjusting the amount of air flowing in, and 31 is a guide plate for preventing blurring of the cylinder rod 16a.

The transfer jacks A and B can be paired using the above-described apparatus, for example, as follows. That is, first, as shown on the left side of FIG. 4, the lever main body 7 a is made horizontal, and both holding plates 5 are removed from the rear wall 4 b of the jack holder 11. Next, as shown in FIG. 5, the levers 10a of the left and right jack pressures 10 are moved in the elongated holes 12a of the slide guide 12 against the gravity of the weights 15a, and are moved outside the bent portions 8b of the stoppers 8 so as to move outward. It is located closer (see the two-dot chain line in FIG. 5). As a result, the jack holder 1
One guide groove 4c comes to the outside. Next,
A large number of transfer jacks A,
Insert B in a row. At this time, of the transfer jacks A and B, the long one A is inserted into the right guide groove 4c, and the short one B is inserted into the left guide groove 4c. The transfer jacks A and B are set in a vertical position with the hooks 2a and 2b facing upward, and the butt 3
a, 3b rest on the upper surface of the rear wall 4b of the jack holder 11. In this state, the hook portions 2a and 2b come out from the upper surface of the front wall 4a of the jack holder 11. Thereafter, the holding plate 5 is fixed to the rear wall 4b by the set lever 7, and the lever 8d of the stopper 8 is turned downward. Thereby, the weight 1 of the lever 10a
5a pulls the jack pressure 10 toward the center by gravity, and the jack pressure 10 pushes the transfer jacks A and B against the guide 13 side.

When the switch 20 is turned on in this state, a timer 27 is operated, and after a set time, the solenoid valve 24 is turned on, and air flows into the cylinder 16. This allows
As shown in FIG. 6, the cylinder 16 is pushed out to move the pair of left and right jack pushing pieces 17 forward, and the jack pushing pieces 17 push the rear portions of the butt portions 3a and 3b of the transfer jacks A and B forward.
The extruded transfer jacks A and B hit the pins 13a provided on the extruding guide 13, rotate around the pins 13a, and tilt forward to be received by the receiving portions 14a formed on the pairing base 14 (see FIG. 7).
At this time, the striker 25 comes into contact with the front electric contact 29 to turn off the solenoid valve 24, so that the air flows out of the cylinder 16 to draw the cylinder 16 into operation. When the cylinder 16 is retracted by a predetermined distance, the striker 25 contacts the rear electrical contact 28 and starts counting for the next extrusion. Then, while the cylinder 16 is waiting for the next pushing, the pair of transfer jacks A and B received by the receiving portion 14a are picked up by hand and inserted into the groove on the upper surface of the transfer dial.

As described above, according to this embodiment, the transfer jacks A and B can be automatically paired, and the time required for the pairing operation can be reduced. For this reason, the time required for the exchange work of the transfer jacks A and B can be greatly reduced. For example, in the case of a pantyhose knitting machine having 400 needles, the above exchange work can be performed in 10 to 20 minutes.

Further, in this embodiment, a jack pressure 10 is provided as a means for pressing the transfer jacks A and B against the push-out guide 13, and a wire 15 having a weight 15a attached to one end of a lever 10a fixed by the jack pressure 10 is provided. It has. Then, the transfer jacks A and B in the guide groove 4c
The transfer jacks A and B can be pressed against the push-out guide 13 with a constant strength by the appropriately set gravity of the weight 15a irrespective of the quantity. For this reason, the jack pressure 10 presses the transfer jacks A and B against the pushing guide 13 with excessive force, making it difficult to push the transfer jacks A and B, and forcing the pushing pieces 17 to push the transfer jacks A and B. Transfer jacks A and B smoothly without damage
Can be extruded. On the contrary, the force for pressing the transfer jacks A and B is insufficient, and a gap is generated between the transfer jacks A and B and the push-out guide 13 without causing troubles such as the transfer jacks A and B not being pushed out. The transfer jacks A and B can be reliably pushed out.

In the jack pairing device of this embodiment, since the set lever 7 having the adjusting screw 7b and the holding screw 7c is attached to the jack holder 11, the attached holding plate 5 can be quickly fixed. By adjusting the pressing force of the holding plate 5 with the adjusting screw 7b and the holding screw 7c, the holding plate 5 can be sufficiently fixed.

In the above embodiment, a jack pressure 10 is provided for each of the transfer jacks A and B as a means for pressing the transfer jacks A and B against the push-out guide 13. The push guide 13 was pressed against the push guide 13, but one weight was provided and both jack pressures 1
0 may be pressed.

In the above embodiment, when the transfer jacks A and B are inserted into the guide grooves 4c, the stoppers 8 are provided so as to resist the pressing of the jack pressure 10, but they are not particularly provided. Is also good. A support for receiving the gravity of the weight 15a is provided below the weight 15a, and the weight 15a is placed on the support to relieve the tension of the wire 15 so that the jack pressure 10a is reduced.
May be released.

Further, in the above embodiment, as means for positioning and holding the holding plate 5 on the jack holder 11,
Although the locking pin 4d and the set lever 7 are provided, the invention is not particularly limited to this. That is, a hinge mechanism is provided at the rear edge of the surface where the receiving table 6 and the pressing plate 5 are in contact with each other, and the pressing plate 5 is rotated clockwise about the hinge mechanism so that the guide groove 4c is opened. Is also good. At this time, a certain amount of gravity may be applied to the pressing plate 5 to sufficiently prevent the transfer jacks A and B from rattling.

In the above-described embodiment, as the means for receiving the forwardly inclined transfer jacks A and B, pins 13a are formed coaxially on both right and left sides of the push-out guide 13. Jack holder 11 may be formed so as to protrude coaxially from the end face on the center side of the front wall 4a. As the receiving means, a receiving portion 14a is not provided on the pairing base 14, but as shown in FIG.
3, a block 33 having an upwardly inclined surface 33a may be formed.
