Description

Description: TECHNICAL FIELD The present invention relates to a sliver feeding method and device in a spinning machine that feeds a sliver to a roller part of a drawing machine, a roughing machine, and the like, and in particular, it is spun from a carding machine. It is effective when supplying the slide bar to the roller part of the drawing machine at high speed.

2. Description of the Related Art Conventionally, as a device for supplying a sliver spun from a carding machine to a draft part of a drawing machine, Japanese Patent Laid-Open No. Sho 60-75619
As disclosed in Japanese Patent Laid-Open No. 60-155730 and Japanese Patent Laid-Open No. 60-155730, a creel having a plurality of lifting rollers that rotate in one direction is arranged behind a roller part, and a sliver is supplied below the lifting rollers. It is known that a reserve box as a source is provided, and a sliver pulled up from the reserve box is hooked on one of the lifting rollers and placed on the lifting roller to supply the sliver.

Problems to be Solved by the Invention In the conventional device, the sliver between the sliver and the lifting rollers pulled up from the reserve box and supplied to the roller part causes an illegal draft between the reserve box and the lifting rollers and between the lifting rollers. There was a problem that the sliver was easily cut during the time when it occurred. In particular, when the sliver supply speed has been increased as in recent years, the sliver's illegal drafts and sliver cutouts increase, which is a big problem.
Further, the same problem as described above also occurs when a sliver is fed into a can by a lifting roller in a kneading machine or a roving machine, and particularly when a comber sliver or the like in which the parallelism of fibers is provided. It was a big problem.

Therefore, in order to solve the above problems, the present invention provides a ring guide that is rotated in one direction by the rotation of a lifting roller in a conveying passage of a sliver, and contacts the sliver with the ring guide. The feature of this is that the sliver is conveyed while being false twisted.

When the working lifting roller rotates, the sliver is pulled up from the sliver supply source, conveyed toward the roller part, and supplied to the roller part. In this case, the rotation of the lifting roller causes the ring guide to rotate in one direction, and the sliver comes into contact with the ring guide to cause rolling of the sliver, resulting in false twisting of the sliver. Therefore, the frictional force between the fibers of the sliver in the sliver pulling up part and the lifting roller bridging part increases, making it difficult for false drafts to occur, making it difficult to cut the sliver, and the false twist of the sliver is almost twisted near the roller part. You can go back and do a good sliver draft in the roller part.

Embodiment FIG. 1 to FIG. 5 show a plurality of carding machines A1, A2 ... An (collectively referred to as carding machine A) and one drawing machine B with an automatic leveler.
This is shown when the sliver forming machine 1 in which is connected is used. As is well known, a roller part 3 is provided in the frame body 2 of the drawing machine B, and a creel 4 as a sliver supply device is provided behind the roller part 3. In the creel 4, reference numeral 5 is a creel beam supported by a plurality of columns 6, and is connected to the frame body 2. A large number of lifting rollers 7 are rotatably supported on the creel beam 5 with a required space. These lifting rollers 7 are rotated in the direction of the arrow by a drive motor of the drawing machine B via a transmission mechanism (not shown) incorporated in the creel beam 5. The lifting roller 7
A ring guide 8 is integrally attached to the lifting roller 7a corresponding to each of the carding machines A1, A2 ... An. The ring guide 8 is a disc 9 that projects like a collar from the peripheral surface of the lifting roller 7a as shown in FIGS.
The outer surface of the disk 9 is a smooth curved surface 9a.
To prevent the sliver S from being caught. A ring-shaped fixed guide 10 is fixed to the creel beam 5 via a mounting bracket 11. The fixed guide 10 is located substantially directly below the ring guide 8 so as to prevent the sliver S with the lifting roller 7 from passing over the ring guide 8. However, depending on the kind of the sliver S, the sliver S is a ring guide. The fixed guide 10 may be omitted if there is no risk of overcoming the number 8. Next, below the lifting roller 7, a calendar roller 12 of a carding machine A exemplified as a sliver supply source is arranged. The spinning ability of the carding machine A is controlled by an inverter so as to be synchronized with the rotation speed of the lifting roller 7 of the drawing machine B as disclosed in Japanese Patent Laid-Open No. 60-155730. . As shown in FIG. 3, the position of the calendar roller 12 is deviated to the side opposite to the sliver hooking portion 13 side with respect to the ring guide 8, and the sliver S spun from the calendar roller 12 is pulled up and lifted. Roller 7a sliver hook
When it is hooked on 13, the sliver S is bent into a dogleg shape and comes into contact with the ring guide 10. The carding machine A is provided with a well-known reserve box 14 below the calender roller 12 so as to temporarily pool the sliver S spun from the calender roller 12 when the supply sliver S is cut.

In the case of the above configuration, the carding machine A is used before the automatic operation.
Of the lifting roller 7a by pulling up the sliver S spun from the calendar roller 12 of
The roller part 3 of the kneading machine B is hooked onto the lifting roller 7 as shown in FIGS. 3 to 5 and placed on each lifting roller 7.
Then, when the automatic operation is started, each lifting roller 7 of the creel 4 rotates in one direction, and the sliver S is spun from the calendar roller 12. The sliver S spun from the calender roller 12 is pulled up by the rotation of the lifting roller 11 and is conveyed toward the roller part 3 and supplied to the roller part 3. In this case, the sliver S pulled up from the calendar roller 12 is the lifting roller 7a as shown in FIGS.
It comes into contact with the surface of the ring guide 8 that rotates together with the ring guide 8 to cause rolling in the direction of the arrow, and false twist is applied. This false twist is well applied to the sliver S between the sliver hooking portion 13 and the calendar roller 12, and between the sliver hooking portion 13 and the next lifting roller 7b, and the sliver S in those portions is twisted.
The strength of. Therefore, it is possible to reduce the false draft and the sliver break in the sliver S and the sliver S between the lifting rollers 7a and 7b when the sliver is pulled up. The false twist of the sliver S is almost returned during the transportation by the lifting roller 7. The ring guide 8 having the above structure can be assembled by simply fixing it to the lifting roller 7a, and can be easily implemented on an existing machine base.

In the above embodiment, the spinning capacity of the carding machine A is made to follow the sliver supply capacity of the drawing machine B, and the sliver S spun from the calendar roller 12 in normal operation is directly pulled up onto the lifting roller 7. However, as shown in FIG. 3 of JP-A-60-75619, when the sliver is pulled up from the reserve box onto the lifting roller in the normal operation, the sliver supply part is constituted by the reserve box. The position of the reserve box may be deviated to the side opposite to the sliver hook portion side with respect to the ring guide. Further, only the position of the fixed guide disposed below the ring guide may be offset to the side opposite to the sliver hooking portion side with respect to the ring guide so that the sliver being pulled up contacts the ring guide. .

FIGS. 6 and 7 show different embodiments of the present application, and show the case where the present invention is applied to a single drawing machine or roving machine. In this embodiment, the positions of the sliver cans 15 and the ring-shaped fixed guide 10e exemplified as the sliver supply part are displaced to the side opposite to the sliver hooking part 13e side with respect to the ring guide 8e of the lifting roller 7ae, and the sliver cans 1
The sliver Se that is pulled up from inside is bent in a V shape and contacts the surface of the ring guide 8e, and false twist is applied to the sliver Se. A ring guide 16 similar to the ring guide 8e is also integrally attached to the lifting roller 7be next to the lifting roller 7ae. The position of the ring guide 16 is offset to the same side as the sliver hooking portion 13e side with respect to the ring guide 8e, and the sliver Se is placed on the sliver hooking portion 17 on the offset side of the ring guide 16. . Therefore, when the sliver Se is supplied by the lifting rollers 7ae and 7be, the sliver Se bends and comes into contact with both the ring guide 8e and the ring guide 16, and the sliver Se becomes an arrow by both the ring guides 8e and 16. False twist is applied in the same direction as indicated by. It should be noted that the same reference numerals as those of the above-described embodiment or equivalent components are denoted by the same reference numerals and the letter e is added to omit duplicate description. Also in the next embodiment, the letter "f" is added in the same manner and duplicate explanation is omitted.

FIG. 8 and FIG. 9 show another different embodiment of the present application, in which the ring guides 8f and 16f are integrally formed on the lifting roller 7af for hooking the sliver Sf that is being lifted and the subsequent lifting rollers 7bf, respectively. Installed on the ring guide 8f, 16f
The sliver Sf is arranged in a meandering manner on the lifting rollers 7af, 7bf such that the positions of the sliver hooking parts 13f, 17f with respect to the sliver are alternately reversed.
In this embodiment, the ring guides 8f and 16f alternately false-twist the sliver Sf between the lifting rollers 7a and 7bf in the opposite direction. Therefore, the sliver Sf being pulled up from the sliver can 15f is the ring guide 8f.
The false twist is applied by the arrow direction (clockwise direction toward the sliver feed direction) in Fig. 9, and the ring guides 8f and 16f are provided on the sliver Sf between the lifting rollers 7af and 7bf.
This time, false twist is applied in the opposite direction (counterclockwise to the sliver feed direction), and between the next lifting rollers 7bf and 7bf, false twist is applied again in the sliver feed direction to the right. .

As described above, according to the present invention, a ring guide that rotates in one direction is arranged in the conveying passage of the sliver, and the sliver is brought into contact with the ring guide during conveyance of the sliver to false twist the sliver. Since the sliver is hung and false twisted while being conveyed, even if the sliver is conveyed using a lifting roller, it is possible to reduce the false draft of the sliver at the sliver lifting portion and the lifting roller bridging portion. At the same time, it is possible to prevent the sliver from breaking at those portions, and it is possible to improve the work efficiency in the sliver supply work and the quality of the spun sliver. In addition, since the ring guide is provided integrally with the lifting roller so that the ring guide rotates in synchronization with the lifting roller, the ring guide can be implemented on an existing machine base at low cost.
