Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an open-end spinning machine using sliver as raw material;
The present invention relates to a method for sliver sliver slitting in a spinning machine such as an adsorption heating spinning machine, in which the work is automatically carried out by a working machine that can run along the spinning frame frame.

[Conventional technology] In recent years, various types of automation have progressed in spinning factories, and sliver can exchange is becoming automated in open-end spinning machines, etc., but sliver spouting still relies on manual labor, which is a bottleneck in labor savings. It becomes. A method of sliver tipping is disclosed in Japanese Patent Application Laid-Open No. 53-81730, which has a sliver passageway that is disposed close to a feed roller that feeds the sliver supplied from a can to a fiber opening device (dividing device) and is open at the top. A guide member is provided in front of the machine so that it can be pulled out, and the guide member is pulled out using a pull rod installed on the working machine, and the end of the sliver stored in the can is gripped by a gripping device installed at the tip of the rotating arm, and the sliver is removed. A method is disclosed in which the sliver is automatically kissed by guiding the sliver into the guide passage of the guide member and then returning the guide member to a predetermined position.

[Problems to be Solved by the Invention] However, in the above method, the gripping device introduces the sliver into the guide passage of the guide member by releasing its grip on the end of the sliver, so the upper side of the guide passage is open. It is composed of a guide groove. During spinning, the sliver is guided by a guide groove that is open at the top and is fed between the feed roller and the presser. Therefore, unlike when using a trumpet-shaped capacitor whose diameter is reduced on the exit side, the sliver is supplied between the feed roller and the presser without being compressed in advance so that it can be easily pinched between the feed roller and the presser. There is a problem in that the supply is not carried out smoothly, causing uneven supply and reducing yarn quality.

The present invention has been made in view of the above problems, and includes:
The purpose is to provide a method for feeding sliver to the spinning unit that can be carried out automatically and reliably, and that does not interfere with the feeding of sliver between the feed roller and the presser. It's about doing.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a working machine that can run along a spinning machine frame that uses sliver as a raw material.
A sliver take-out device that takes out sliver from a can, a capacitor take-out device that takes out a capacitor that is installed in a spinning unit and is formed so that the exit side is reduced in diameter, and a sliver take-out device that takes out sliver from the exit side of the condenser. means is provided, and with the working machine stopped at a position corresponding to the spinning unit where the sliver tip is to be worked, the condenser is taken out from the spinning unit,
While taking out the sliver from the can, the sliver connected to the can is placed on the inlet side of the condenser, and in this state, the sliver end is pulled out from the outlet side of the condenser by the sliver take-up means, and then the gap between the feed roller and the presser is widened. After the capacitor was returned to a predetermined position in the spinning unit and the sliver end was inserted between the feed roller and the presser, the spacing between the feed roller and the presser was returned to the spacing at the time of spinning.

[Function] In the method of the present invention, when the sliver tip is attached by the work machine, the capacitor is taken out from the spinning unit and placed in a predetermined position, and the sliver is taken out from the can by the sliver take-out device, and the sliver connected to the can is placed in the condenser. located on the entrance side. In this state, the sliver taking-off means acts on the sliver from the outlet side of the condenser, the sliver end is pulled out to the outlet side, and then the condenser is returned to a predetermined position in the spinning unit. At this time, the distance between the feed roller and the presser is arranged to allow the sliver end to pass through, and after the sliver end is inserted between the feed roller and the presser, the distance between the feed roller and the presser is adjusted to the same distance as the spacing at the time of spinning. When the sliver tip is restored, the work is completed.

The sliver S end gripped by the gripping device 17 can be placed above the capacitor 4 taken out from the spinning unit 2 to the sliver insertion position, and can be rotated to the position shown in FIGS. 3 and 6. . Further, the gripping device 17 is opened and closed by a solenoid. The guide device 20 is composed of a cylinder, and when the working machine 16 stops at a predetermined position corresponding to the spinning unit 2 for the sliver opening operation, the guide device 20 is located at a position where it can be inserted into the guide holes 13 and 14 of the condenser 4 and the presser 6 and the operation is performed. The guide rod 24 has a guide rod 24 that can be moved in and out of the standby position in the machine 16, and the guide rod 24 extends parallel to the stud 11 that supports the capacitor 4, and the axis of the guide hole 13°14 and the axis of the guide rod 24 are parallel to each other. It is fixed at a position that is slightly offset from the .

The capacitor extractor 19 is provided with a capacitor extractor arm 26 driven by a four-bar parallel link 25 extending parallel to the guide rod 24, and a slit 15 formed in the capacitor 4 at the tip of the extractor arm 26.
A solenoid 28 (shown in dashed lines in FIG. 5(a)) is equipped with a pin 27 that can be engaged with the solenoid 28 (shown in dashed lines in FIG. 5(a)). Also, nipper 2

2 and the sliver cut roller 23 (positions shown in FIGS. 1(h) and 1(i)).

Next, the sliver machining operation by the working machine 16 constructed as described above will be explained.

The working machine 16 is located at the position corresponding to the spinning unit 2 where sliver cutting is required due to sliver breakage, can replacement, etc.
After the sliver gripping arm 18 has stopped, the sliver gripping arm 18 is rotated to a position where it grips the sliver S in the can 3, as shown in FIG. Also, the guide device 20 is operated and the guide rod 2
4 is projected toward the guide hole 13 of the capacitor 4. As shown in FIG. 4(a), when the capacitor 4 is placed in a predetermined position, the guide rod 24 and the guide hole 1
3 has its axis shifted, so after the tip of the guide rod 24 engages with the guide hole 13, the guide rod 24
As the capacitor 4 moves forward, the capacitor 4 together with the presser 6 is rotated counterclockwise in FIG. 4(b) about the stud 1 against the biasing force of the spring 12. Then, the guide rod 24 stops at the position where its tip is inserted into the guide hole 14 of the presser 6, and the distance between the presser 6 and the feed roller 5 is equal to the sliver as shown in FIGS. 5(a) and 5(b). The distance 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, the gripping device 17 grips the sliver S, and the sliver gripping arm 18
is rotated to a predetermined sliver insertion position, resulting in the state shown in FIG.

Next, the capacitor extractor 19 is activated, and the capacitor extractor arm 26 is placed at a position where its tip corresponds to the slit 15 of the capacitor 4, as shown by the chain line in FIG. In this state, the solenoid 28 is activated to project the pin 27 into the slit 15, and then the capacitor extraction device 19 is activated again to move the capacitor extraction arm 26 backward.

Then, as the capacitor pull-out arm 26 moves, the capacitor 4 is moved along the guide rod 24 to the sliver insertion position. During the movement of the capacitor 4, the gripping device 17
When the sliver S hanging down from the capacitor 4 is introduced into the guide passage 4a and the capacitor 4 is placed at a predetermined sliver insertion position, the state shown by the solid line in FIG. 6 is reached.

Next, the sliver is inserted into the capacitor body 10 according to FIG. Sliver cut roller 23 and nipper 22 placed in the open position as shown in FIG. 1(a)
The sliver insertion wire 21 moves toward the outlet 10a of the capacitor body 10 through the gap, enters the capacitor body 10 from the outlet 10a, and stops at the position where the hooking part 21a passes below the sliver S. Figure 1 (b
). In this state, the gripping device 17 releases the sliver S, and the sliver S falls to the seventh position.
As shown in the figure, the end of the sliver S is connected to the capacitor body 1.
It passes behind the entrance part of 0 and hangs down. As a result, the sliver S is guided to the stepped portion 4b of the guide passage 4a and placed on the sliver insertion wire 21 (see FIG. 1).
The state becomes C).

Next, the sliver insertion wire 21 is pulled back and the hooking part 21
a is moved toward the exit 10a side, and during the movement, the first
As shown in Figure (d), the sliver S is guided inside the hook 21a. Since the hooking portion 21a is arranged so as to be located on a plane including the diagonal line of the outlet 10a, the hooking portion 21a
As the sliver 1a moves, the sliver S is reliably guided inside the hook 21a. The movement of the sliver insertion wire 21 continues from the state shown in FIG. 1(d), resulting in the state shown in FIG. 1(e).

As shown in (f), the capacitor body 1O is pulled out from the outlet 10a, and the sliver S is also pulled out from the outlet 10a. After the hook 21a passes the sliver cut roller 23, the nipper 22 is moved to the nip position as shown in FIG. 1(g), and the sliver S is gripped by the nipper 22 near the outlet 10a. After the sliver insertion wire 21 returns to the standby position and the sliver S is pulled out from the hooking part 21a as shown in FIG. 1. The sliver S is rotated in the direction of the arrow in Fig. 1 (i), and the sliver S is
and the sliver cut roller 23. Therefore, the length of the sliver S protruding from the outlet 10a of the capacitor body 10 is always a length suitable for sliver gating.

Next, the capacitor pull-out arm 26 is again moved to the forward position shown by the chain line in FIG. At this time, the presser 6 is held at a position that allows the passage of the sliver S from the feed roller 5 by the guide rod 24, so that when the capacitor 4 is attached to the stud 11, the outlet 10a
The end of the sliver S protruding from the feed roller 5 is securely inserted between the feed roller 5 and the presser 6 as shown by the chain line in FIG. 5(b). Next, after the solenoid 28 is demagnetized and the pin 27 is removed from the slit 15, the capacitor pull-out arm 26 is moved backward to the standby position. On the other hand, the guide device 20 is operated and the guide rod 24 is retracted, and the guide rod 24 is disengaged from the guide holes 14 and 13 of the presser 6 and the condenser 4, and the presser 6 and the condenser 4 are placed in predetermined positions by the action of the spring 12. Return. As a result, the end of the sliver S is transferred to the feed roller 5.
and the presser 6, and the mouthing operation is completed.

After the splicing operation is completed, if the work machine 16 is equipped with a yarn splicing device, the yarn splicing operation is continued. On the other hand, when the working machine 16 is used only for sliver tipping work, the working machine 16 starts traveling after the work is completed, and the tipping is located at the position corresponding to the spinning unit 2 that requires the work. After stopping and repeating the same operation, the spinning unit 2 after the splicing operation is spliced by a splicing machine, and then spinning is restarted.

Note that the present invention is not limited to the above embodiments,
For example, a tapered guide surface may be provided on the entrance side of the guide hole 13, the capacitor drawing arm 26 may be configured to operate with a cylinder, or when the sliver insertion wire 21 draws out the end of the sliver from the outlet 10a, In order to ensure that the length of the protruding sliver end is suitable for kissing, the sliver tipper is designed to stop the sliver gripping arm 18 at a position where the gripping device 17 is located close to the capacitor body lO during operation. Configure nipper 2
2 and the sliver cut roller 23 may be omitted. Also, instead of arranging the presser 6 at a position where there is a gap between it and the feed roller 5 that allows the passage of the end of the sliver by the action of the guide rod 24, a cam surface that engages with the presser 6 is provided on the capacitor 4. It is also possible to form a cam surface so that the presser 6 is temporarily placed in a position that allows the sliver end to pass through. Furthermore, as the sliver drawing means for inserting the end of the sliver S into the capacitor body 10, a method of applying suction airflow to the sliver S from the outlet 10a side may be used.

[Effects of the Invention] As detailed above, according to the present invention, the operation of attaching the sliver to the spinning unit can be carried out automatically and reliably, and the condenser has a reduced diameter on the outlet side. Since the sliver is inserted through the presser, the sliver is smoothly fed between the feed roller and the presser, and deterioration in the quality of the spun yarn can be prevented.
