A holding tool 53 that can swing around the center is provided, and the holding tool 53 is driven by a rotary actuator 54.

Next, a processing method using the above device will be explained.

A large number of stocking fabrics 20 are randomly stored in the packet 18, and the elevating body 7 is lowered while being rotated by the motor 19, and the vacuum suction port 10 or the grip claw 1 is lowered.
3 grabs the stocking fabric 20 and raises the elevating body 7.

When the sensor 16 detects the lower end of the stocking fabric 20 rising together with the elevating body 7, the elevating body 7 stops.

Next, the rotless cylinder 8 is operated to move the lifting tool 9 to the position indicated by the chain line in FIG.

Since the lower end of the stocking fabric 20 is at the same height as the rotating pipe 24 according to the sensor 16, the suction port 27 of the rotating vibe 24 faces the lower end of the stocking fabric 20 at this position, and is connected to the hollow rotating shaft 22. Since the solenoid valve 25 is also open during suction by the vacuum suction device, when the lower end of the stocking fabric 20 comes to one end of the rotating pipe 24, it is sucked into the rotating vibrator 24.

At the same time, the hoisting tool 9 releases stocking fabric raising.

At this time, if the lower end of the stocking fabric 20 is the toe, the stocking fabric 20 is sucked into the rotating vibrator 24 without resistance, and its tip is detected by the sensor 26, and the waistband part 29 of the stocking material 20 is moved as shown in FIG. When located at the suction port 27 of the rotating pipe 24 as shown by the chain line, the stocking fabric 20 inside the vibrator 24 rotates 180° together with the vibrator 24 and faces the suction part 33 of the reversing vibe 30. At this opposing position, the solenoid valve 25 is closed and the suction of the vibrator 24 is stopped.

Since the suction part 33 has a large diameter, the stocking fabric 2
0 is sucked from the waistband portion 29 into the reversing vibe 30 and further into the supplying vibe 35.

In addition, if the lower end of the stocking fabric 20 that has come to the turning pipe 24 is the waistband part 29 as described above, the waistband part 29 has a much thicker material than the toes, so the turning pipe 24 It is not sucked into the suction port 27 and is sucked, and since it is no longer sucked, it hangs down with its toes down.

In this state, the stocking fabric 20 is not detected by the sensor 26, so the signal from the sensor 26 is sent to the motor 31, and the motor 31 moves the reversing vibrator 30 to 18.
Rotate it by 0° so that the suction part 33 is on the lower side as shown by the chain line in FIG.

On the other hand, the rotating pipe 24 by the motor 23 rotates 180 degrees to move the toe of the hanging stocking fabric 20 to the second position.
Since the stocking fabric 20 is made to face the suction part 33 as shown in FIG.

At this time, the solenoid valve 25 is closed and the suction of the vibrator 24 is stopped.

As mentioned above, the stocking fabric 20 is attached to the suction vibrator 35 with either the toe or the waistband portion 29 at the top.
sucked inside.

After that, the effect is as mentioned above. It is almost the same as that described in 56685 publication.

That is, when the leading end of the stocking fabric 20 supplied from the supply vibrator 35 to the vibrator 44 is the toe, the solenoid valve 46 is opened and the solenoid valve 47 is closed, so that the airflow by the vacuum suction device flows toward the blocking plate 50. The stocking fabric 20 is temporarily stored in a compressed state at the toe of the blocking plate 50.

Then, by closing the electromagnetic valve 46 and opening the electromagnetic valve 47, the airflow flows toward the blocking plate 51.
The stocking fabric 20, which has been waiting at the section , enters the delivery device 36 from the waistband section 29 and is stopped when it hits the stop plate 51. For this action, it is preferable to provide a nozzle on the left side of the blocking plate 50 to inject the airflow.

When the waistband portion 29 reaches the right end in this manner, the rotary actuator 54 is activated to rotate the presser 53 below the elongated hole of the stopper plate 51 as shown in FIG.
Waistband part 2 of stocking fabric 20 as shown in C
Hold 9.

In this state, the solenoid valve 47 is closed again, and the solenoid valve 46 is opened to cause the airflow in the delivery device 36 to flow to the left, thereby stretching the stocking fabric 20 to the left with the two waistband portions on the right.

At this time, it is preferable to provide a nozzle at the right end of the delivery device 36 to inject the airflow.

Next, when the two electromagnetic valves 46 and 47 are closed and the cylinder 42 is operated to open the opening/closing semi-cylinder 39, the stocking material 20 with the waistband portion 29 on the right side is dropped.

Also, the stocking fabric 2 supplied from the supply vibe 35
If the beginning of 0 is the waistband part 29, the solenoid valve 46 is closed, the solenoid valve 47 is opened, the airflow is caused to flow to the right, and the waistband part 29 is placed to the right in the delivery device 36 and the stop plate 51
After that, the stocking fabric 20 with the waistband portion 29 on the right side can be removed by the same operation as in the case of the stocking fabric 20 described above.

By repeating the above operations, the stocking fabric 20 with the waistband portion 29 on the right side is neatly accumulated in a collection box (not shown) provided at the bottom of the delivery device 36. However, in addition to the embodiments described above, the waistband portion 29 can also be aligned to the left.

Incidentally, the apparatus for carrying out the method of this invention is suitable as an apparatus for supplying stocking fabric for the invention previously filed by the present applicant (Japanese Patent Application No. 62-224454). That is, the device of this earlier application has a vertically cylindrical vacuum suction means that can be opened and closed, a disc-shaped rotary table that rotates around a vertical axis and has a friction ring fixed on its outer periphery, and the vacuum suction A freely rotatable endless belt that can be contacted and separated is arranged above the means on the outer periphery of the table, and a small hole is provided at the upper end of the vacuum suction means for locking the waistband portion of the upper end of the vacuum-suctioned material with the toe as the lower end. is provided, and the waistband part protruding above the small hole is rotated on the side by a rotation i".
- The material is clamped by the peripheral edge of the pull and the endless belt in contact with the peripheral edge, and the vacuum suction means that has stopped suction is released to release the material, and the material is transferred by the table and belt to the next part of the fixed guide. a waistband forming means that pinches the waistband protruding above the guide and table to give it a normal shape while the material sandwiched between the guide and the table is moved together with the table; A waistband that holds the waistband portion of two materials horizontally vertically by holding the waistband portion horizontally and holding the waistband portion sideways by the holding means. A holding means for the band portion;
Expand the waistband held by the holding means and rise! ll! This is a device for attaching pantyhose material to a first manufacturing machine.

Therefore, the supply vibrator 35 shown in FIG. 2 of the device embodying the present invention is attached to the pantyhose material attachment device using a vertically cylindrical shape that can be opened and closed for vacuum suction. facing the top of the means,
The stocking fabric that has moved inside the suction vibrator 35 with the toe at the top may be used as a pantyhose material to be sucked by the vacuum suction means.

However, some suction vibrators 35 move with the waistband section at the beginning, so in this case, either a switching valve is used to prevent it from entering the vacuum suction means, or
Only the stocking fabric with the toes at the top may be suctioned by the suction vibrator 35.

Effect> As described above, the method of this invention involves lifting a part of a large number of randomly stored stocking fabrics using a lifting tool until the lower end is at a predetermined position, and Since this part is sucked by the suction port of the vacuum suction-type rotating vibrator, even if several pieces of stocking fabric are lifted up at the same time, only the stocking fabric hanging at the bottom will be sucked into the rotating pipe.
The other stocking fabrics return to their original positions and wait for the next donation, so the stocking fabrics can be sucked up one by one without the need for human intervention.

In addition, when the toe of the stocking fabric that has been sucked is at the top, it is sucked until the waistband is near the suction port, then it is rotated, the waistband is sucked into the next vacuum suction reversing pipe, and the rotation is performed. When the waistband part of the stocking fabric is sucked by the suction port of the vibrator and becomes droopy, turn the inverted pipe over and place the suction port near the toe of the stocking fabric hanging down, and then insert the stocking from the toe to the inverted pipe. Since the device sucks the fabric, even stocking fabric in a random state can be sent to the next aligning and discharging device in an orderly manner, with either the waistband or the toe at the beginning. The process of aligning the stocking fabric in the direction can be done efficiently by using a toothpick, and the subsequent processing of the stocking fabric becomes easy.
