Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention travels a sliver opening work in a spinning machine such as an open-end spinning machine or an adsorption twisting spinning machine using a sliver as a raw material along a spinning machine stand. The present invention relates to a sliver knurling method automatically performed by a possible working machine.

[Prior art] In recent years, various kinds of automation have been advanced in spinning factories, and sliver ken exchange has been automated in open-end spinning machines and the like. However, sliver knitting work still depends on human labor, which is a bottleneck for labor saving. ing. Japanese Patent Application Laid-Open No. 53-81730 discloses a guide member having a sliver passage which is disposed close to a feed roller for feeding a sliver supplied from a can into a fiber opening device (split device) and has an upper opening. Is provided so that it can be pulled out to the front of the machine base, the guide member is pulled out by a pull rod provided on the working machine, and the end of the sliver contained in the can is gripped by the gripping device provided at the tip of the turning arm to guide the sliver. A method of automatically slivering the sliver by returning the guide member to a predetermined position after guiding the sliver into the guide passage of the member is disclosed.

[Problems to be Solved by the Invention] However, in the above-described method, the upper side of the guide passage is opened because the holding device releases the holding of the sliver end to introduce the sliver into the guide passage of the guide member. It is constituted by a guide groove. Then, the sliver is guided by the guide groove whose upper part is opened at the time of spinning, and is supplied between the feed roller and the presser. Therefore, unlike the case of using a trumpet-shaped condenser in which the outlet side has a reduced diameter, the sliver is supplied between the feed roller and the presser without being compressed in advance so that the sliver is easily sandwiched between the feed roller and the presser. There is a problem in that the supply is not performed smoothly, the supply is uneven, and the yarn quality is reduced.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to automatically and reliably perform a sliver knitting operation to a spinning unit, and furthermore, a sliver between a feed roller and a presser. An object of the present invention is to provide a sliver kissing method that does not hinder supply.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, a sliver take-out device that takes out a sliver from a can to a work machine that can travel along a spinning machine stand that uses a sliver as a raw material, A condenser take-out device, which is equipped on the spinning unit and takes out the condenser formed so that the outlet side has a reduced diameter from the spinning unit, and a sliver taking-out means for taking out the sliver from the outlet side of the condenser are provided. With the spindle stopped at the position corresponding to the spinning unit requiring work, take out the condenser from the spinning unit, take out the sliver from the can, place the sliver connected to the can at the condenser inlet side, and pull the sliver in that state. After pulling out the sliver end from the outlet side of the condenser by the After the condenser is returned to the predetermined position of the spinning unit with the distance between the dressers expanded, the sliver end is inserted between the feed roller and the presser, and then the distance between the feed roller and the presser is returned to the spinning distance. I made it.

[Operation] In the method of the present invention, the capacitor is removed from the spinning unit and placed at a predetermined position during the sliver tying operation by the working machine, the sliver is removed from the can by the sliver removal device, and the sliver connected to the can is connected to the inlet of the capacitor. Placed on the side. In this state, the sliver take-off means acts on the sliver from the outlet side of the condenser to draw out the sliver end to the outlet side, and then the condenser is returned to a predetermined position of the spinning unit. At that time, the distance between the feed roller and the presser is set to allow the passage of the sliver end, and after the sliver end is inserted between the feed roller and the presser, the distance between the feed roller and the presser is changed to the distance at the time of spinning. And the sliver kissing operation is completed.

And a position retreated from the position between the nipper 22 and the sliver cut roller 23 (the position shown in FIGS. 1 (h) and 1 (i)).

Next, a sliver knitting operation by the working machine 16 configured as described above will be described.

At the position corresponding to the spinning unit 2 where sliver mashing was required due to sliver breakage, can exchange, etc.
Is stopped, the sliver gripping arm 18 is rotated to a position for gripping the sliver S in the can 3 as shown in FIG. Further, the guide device 20 is operated, and the guide rod 24 is projected toward the guide hole 13 of the condenser 4. As shown in FIG. 4 (a), when the condenser 4 is arranged at a predetermined position, the axes of the guide rod 24 and the guide hole 13 are shifted. And since the tip of the guide rod 24 is tapered, the guide rod 24 can enter the guide hole 13 while the tip is tapered, even if the axis is shifted, and the axis of the tip of the guide rod 24 is The lower portion engages with the lower portion of the inner surface of the guide hole 13. When the guide rod 24 further advances after the tip of the guide rod 24 engages the guide hole 13, the capacitor 4 and the presser 6
4B, is rotated counterclockwise in FIG. 4B to the position where the axis of the guide hole 13 coincides with the axis of the guide rod 24. . Then, the guide rod 24 stops at a position where its tip is inserted into the guide hole 14 of the presser 6, and as shown in FIGS. 5 (a) and 5 (b), the interval between the presser 6 and the feed roller 5 is sliver. The state is maintained at a distance that allows the passage of S. On the other hand, while the guide rod 24 moves to the protruding position,
17 grasps the sliver S, and the sliver grasping arm 18 is rotated to a predetermined sliver insertion position to be in the state shown in FIG.

Next, the condenser take-out device 19 is operated, and the condenser take-out arm 26 is disposed at a position corresponding to the slit 15 of the condenser 4 as shown by a chain line in FIG.
In this state, the solenoid 28 is operated and the pin 27 is slit.
After being projected into 15, the condenser take-out device 19 is operated again, and the condenser take-out arm 26 is moved backward. Then, the condenser 4 is moved to the sliver insertion position along the guide rod 24 with the movement of the condenser draw-out arm 26. During the movement of the condenser 4, the sliver S hanging from the holding device 17 is introduced into the guide passage 4a,
When the capacitor 4 is placed at the predetermined sliver insertion position, the state shown by the solid line in FIG. 6 is obtained.

Next, the operation of inserting the sliver into the capacitor body 10 is performed according to FIG. As shown in FIG. 1 (a), the sliver insertion wire 21 moves toward the outlet 10a of the capacitor main body 10 through the space between the sliver cut roller 23 and the nipper 22 disposed at the open position. Ten
And stops at the position where the hooking portion 21a has passed below the sliver S, and the state shown in FIG. 1B is obtained. In this state, the gripping of the sliver S by the gripping device 17 is released, and the sliver S falls and the end of the sliver S hangs down behind the entrance of the condenser body 10 as shown in FIG. . As a result, the sliver S is guided to the step portion 4b of the guide passage 4a, and the sliver insertion wire 21
(C) of FIG.

Next, the sliver insertion wire 21 is pulled back, and the
Is moved toward the outlet 10a, and the sliver S is guided to the inside of the hooking portion 21a during the movement as shown in FIG. 1 (d). Since the hook 21a is located on a plane including the diagonal line of the outlet 10a, the sliver S is reliably guided to the inside of the hook 21a as the hook 21a moves.
The movement of the sliver insertion wire 21 is further continued from the state of FIG. 1 (d), and the sliver S is pulled out from the outlet 10a of the capacitor body 10 as shown in FIGS. 1 (e) and 1 (f).
Is also withdrawn from exit 10a. After the hook 21a has passed through the sliver cut roller 23, the nippers 22 are moved to the nip position as shown in FIG.
Is gripped by the nipper 22 in the vicinity of. Then, after the sliver insertion wire 21 returns to the standby position and the sliver S comes out of the hooking portion 21a, as shown in FIG. 1 (h), the sliver cut roller 23 is placed at the sliver gripping position and 1 The sliver S is rotated in the direction of the arrow in FIG. 1 (i), and is cut between the nipper 22 and the sliver cut roller 23. Therefore, the length of the sliver S protruding from the outlet 10a of the capacitor body 10 always becomes a length suitable for sliver opening.

Next, the condenser pull-out arm 26 is again moved to the forward position shown by the chain line in FIG. 6, and the condenser 4 is guided and moved by the guide rod 24, and is mounted on the stud 11 of the spinning unit 2. At this time, the presser 6 is a guide rod
24, the sliver S is held at a position that allows the sliver S to pass from the feed roller 5 so that when the condenser 4 is mounted on the stud 11, the end of the sliver S protruding from the outlet 10a is connected to the fifth end. It is securely inserted between the feed roller 5 and the presser 6 as shown by a chain line in FIG. Next, after the solenoid 28 is demagnetized and the pin 27 is released from the inside of the slit 15,
Is moved backward to the standby position. On the other hand, the guide device 20 is operated, and the guide rod 24 is retracted.
24 is separated from the guide holes 14 and 13 of the presser 6 and the condenser 4, and the presser 6 and the condenser 4 return to predetermined positions by the action of the spring 12. Thereby, the end of the sliver S is gripped between the feed roller 5 and the presser 6, and
The kissing operation ends.

After the knitting operation, if the work machine 16 is equipped with a piecing device, the piecing operation is continued. On the other hand, when the working machine 16 performs only the sliver knitting work, the working machine 16 starts running after the knitting work is completed, stops at a position corresponding to the spinning unit 2 requiring the knitting work, and performs the same work. Is repeated, and the spinning unit 2 after the end of the knitting operation is spliced by the splicing machine, and then spinning is resumed.

The present invention is not limited to the above-described embodiment.For example, a tapered guide surface may be provided on the inlet side of the guide hole 13, a configuration in which the capacitor draw-out arm 26 is operated by a cylinder, or a sliver insertion wire. When the sliver end is pulled out of the outlet 10a from the outlet 10a, the sliver gripping arm 18 is held by the gripping device 17 during the sliver opening work so that the length of the sliver end protruding from the outlet 10a becomes a length suitable for staking. The nipper 22 and the sliver cut roller 23 may be configured so as to stop at a position arranged near the position 10, and omit the sliver cut roller 23. Also, guide rod 24
In place of the configuration in which the presser 6 is disposed at a position having a gap allowing passage of the sliver end between the feeder 5 and the feed roller 5 by the action of The presser 6 may be temporarily arranged at a position where the sliver end is allowed to pass by the action of (1). Further, the end of the sliver S is inserted into the capacitor body 10 as sliver take-up means, and the outlet is provided.
A method of applying a suction airflow to the sliver S from the 10a side may be used.

[Effects of the Invention] As described above in detail, according to the present invention, the sliver can be automatically and reliably attached to the spinning unit, and the sliver is inserted into the condenser whose outlet side has a reduced diameter. As a result, the sliver is smoothly supplied between the feed roller and the presser, and the quality of spun yarn can be prevented from deteriorating.
