Positioning method of empty bobbin in textile machine [Technical field]

The present invention relates to a method for supplying empty bobbins in a textile machine such as a ring spinning machine, a draw twister, and a twisting machine.

(Background technology)

Transfer rails arranged along spindle rows of spinning machines

'Rui supplies an egg tray with an empty bobbin from the end of the machine onto a mounting transfer member such as a transfer belt, and supplies it to the pipe change position on the mounting transfer member corresponding to each spindle. In the pipe replacement work to replace the empty tray with the full bobbin on a machine such as a spinning frame in batches, the empty tray with empty bobbin A better positioning accuracy is required for the train rows. An empty bobbin supply system using a transfer rail is disclosed in Japanese Patent Application Laid-Open No. 57-161133, in which a dog tray having a concave portion on the lower surface is about a spindle row pitch. A pipe is supplied from the end of the machine onto the transfer rail that is driven back and forth, and each spindle and the corresponding tube changer cooperates with the transfer rail and the transfer claw that can be engaged and disengaged with the recess as the transfer rail reciprocates. This feeding method, which can supply to the position, is more advantageous than the transfer belt method in positioning the dog tray.

Moderate positioning accuracy can be obtained. However, the feeding of empty trays with empty bobbins onto the loading / transferring members called transfer rails is performed by feeders that use a constantly driven conveyor or drop feeders that use slopes. Even when the machine is operating other than during the change, the supply pressure acts on the empty tray with the bobbins aligned on the change position on the mounted transfer member. Or the vibration of the machine drive acts on the beg tray with empty bobbin above the transfer position. For this reason, there is a disadvantage that the empty tray with the empty bobbin at the relocation position is shifted to a position that hinders the exchanging operation, and smooth exchanging operation cannot be expected.

Therefore, in the present invention, a peg tray provided along each of the spindle rows is provided for a textile machine such as a ring spinning machine in which a large number of spindles are arranged in parallel in the machine direction. An egg tray with an empty bobbin is introduced from one end of a machine base onto the loading / transporting member of the transporting means, and the reciprocating motion of a predetermined stroke is provided to the loading / transporting member. A method of sequentially supplying the dog tray with an empty bobbin to each pipe change position on the mounting transfer member corresponding to each of the spindles by repeating the one cycle transfer operation of the above. Immediately before the start of the refilling operation of the refilling means for exchanging the full bobbin on the bindle and the empty bobbin on the above-mentioned tray, the transfer operation of the above-mentioned tray transfer means is performed at least once. . .

That is, the pair of spindle trains is paired with the spindle train by the above-mentioned drag tray transfer means. After the empty bobbin supply to the corresponding position is completed, immediately before the start of pipe replacement, the above-mentioned transfer operation of the dog tray is performed for at least one cycle. By this cycle operation, an empty tray with empty pobins is arranged at each of the above-mentioned refill positions, and a large number of empty bobbins on the tray and full bobbins on the spindle thus arranged at the refill positions are provided. Batch replacement is performed without any problem.

The hydraulic cylinder mechanism 26 is operated based on the transmission of the doffing signal, and the empty bobbin 30 on the transfer rails 13 and 19 and the bobbin 29 on the spindle 9 are exchanged via the intermediate peg 10. . Next, the operation of the present embodiment will be described with reference to the flowchart of FIG.

By the bobbin request signal from the winder 8 after the completion of the refilling, all the bogie trays with bobbins on the transfer rails 13 and 19 have been replaced by bobbin trays with empty bobbins, and each of the rails 13, 19, 21, air cylinders 14, 20, 23, feed lever 22 and lead switches S1a, S1b, S2a, S2b, S3a, S3b. The tray transfer means is in the arrangement state command (hereinafter referred to as the initial state) in FIG. When the doffing starts, the air cylinder 20 protrudes, whereby the transfer rail 19 is taken up as shown in FIG. 4 (a). As it moves forward to the feed conveyor 3 side, the lead switch S 2 a is strongly switched to 0N, and the lead switch S 2 b is turned off. The air cylinder 23 is protruded by the OFF signal of the lead switch S2b, the feed lever 22 moves forward as shown in FIG. 4 (b), and the lead switch S3 a is set to 0N, lead switch S 3 b Forced OFF. In response to the ON signal of the lead switches S3a and S2a, both air cylinders 14 and 20 are immersed, and the transfer rail 13 moves to the direction change rail 21 side as shown in FIG. 4 (c). At the same time, the lead switch S 1 a is turned off, the lead switch S ib is turned on, the transfer rail 19 moves back to the direction change rail 21, and the lead switch S is turned off. 2a is turned off, and lead switch S2b is turned on. In the course of the reciprocating movement of the transfer rails 13 and 19, the beg tray 5 with empty bobbins on the transfer rails 13 and 19 is transferred by the forward movement of the transfer rails 13 and 19, and is moved by the forward movement. As shown in a) and (b), the tip of the locking piece 16 has the recess 5a of the leading egg tray 5A with empty bobbin and the recess of the trailing egg tray 5B with empty bobbin 5B. Change to 5a. When the transfer rails 13 and 19 return, the tip of the locking piece 16 abuts in the recess 5 a of the subsequent empty bobbin tray 5 B, and the empty bobbin Ray 5 is prevented from retreating. Therefore, by one reciprocating operation of the transfer rails 13 and 19, the egg tray 5 with an empty bobbin on the transfer rail 13 is transferred to the direction change rail 21 by the pitch of nine rows of spindles. The empty tray 5 with empty bobbins on the transfer rail 19 is transferred to the take-out conveyor 3 by the pitch described above, and the empty bobbin on the transfer rails 13 and 19 is attached. Dog tray 5 is placed at the replacement position.

Subsequently, the air cylinder 23 is immersed by the ON signal of the double switches S 1 b and S 2, and the feed lever 22 is returned to the initial state as shown in FIG. 4 (d). To the soldier, the dossic switch S3a is switched off and the lead switch S3b is switched on.-The reversal of the transmission lever 22 causes a change in the direction switch 21 on the transfer rail 13. The empty tray 5C with the empty bobbin at the communication part is transferred onto the turning rail 21 and, accordingly, the empty bobbin at the communication part with the transfer rail 19 on the turning rail 21. The attached tray 5 is transferred onto the transfer rail 19. In response to the ON signal of the lead switch S3b, the air cylinder 1: protrudes and the transfer rail 13 returns to the supply conveyor 2 side, and the lead switch S1a or * 0N. , Lead switch S1b is turned off. When the transfer rails 13 return, the egg tray transfer means returns to the initial state shown in FIGS. 4 (e) and 1 and stops.

In this way, the tag tray transfer means performs one cycle transfer operation from the initial state to the initial state as shown by F in FIG. 5, whereby the transfer rails 13 and 19 are transferred. With an empty bobbin above, even if the Zug tray 5 is displaced from the replacement position due to the influence of the shake while the machine is operating, it will be aligned with the transfer position and the subsequent replacement will be performed without any trouble. You. That is, the present invention can sequentially supply the egg tray 5 with the empty bobbin to the transfer position on the transfer rails 13 and 9 corresponding to the spindles 9 by repeating one cycle transfer operation. One-cycle transfer operation F of the tray transfer means In this embodiment, the arrangement of the dog tray 5 with an empty bobbin to the change position is changed in the most accurate state by linking the off-set command signal and the one-cycle transfer operation F. The operation can be performed.

In this embodiment, the transfer operation of the egg tray transfer means prior to the pipe change is performed only in one cycle, but the transfer operation may be performed in two or more cycles.

When the pipe replacement operation is completed as described above, the cycle transfer operation F is performed by the full bobbin request signal from the winder 8. This cycle transfer operation F is performed by the counting device 25. Stops until the number of tray counts reaches the specified value, that is, until the full bobbin 29 on the transfer rails 13 and 19 corresponding to the nine rows of spindles replaces the empty bobbin 30 and then stops. Is done.

The present invention is not limited to the above-mentioned embodiment. For example, instead of the doffing command signal, the one-cycle transfer operation F of the bung tray transfer means is performed based on a full notice signal. The transfer may be performed before the pipe change, or the worker may perform the one-cycle transfer operation of the bag tray transfer means by operating the push button based on the full notice lamp.

Further, the supply stopping device 24 can be omitted in the above-described embodiment. Even in such a case, the positional displacement of the empty tray 5 with the empty bobbin caused by the supply pressure of the supply conveyor 2 can be reduced. It can be absorbed by the one-cycle transfer operation of the kit tray transfer means. Further, the present invention is also applicable to an empty bobbin supply system disclosed in Japanese Patent Application Laid-Open No. 57-161133. As described above in detail, according to the present invention, the empty tray with the bobbin can be sequentially supplied to each of the replacement positions on the mounting transfer member corresponding to each of the spindles by repeating the operation of one cycle of the transfer operation. Since the transfer operation of the above-mentioned tag tray transfer means is performed at least one cycle immediately before the start of the pipe change, the vibration of the machine or the supply pressure is applied to the tag tray with an empty bobbin on the mounting transfer section 栻. In the case of pipe replacement, the empty tray with empty bobbin can be properly aligned at the pipe replacement position on the loading and transferring member even if the pipes have the adverse effect of causing displacement. This has an excellent effect that the replacement can be performed without any trouble.
