Description

[Detailed Description of the Invention] [Industrial field of application] A fleece guide arranged immediately in front of a front detaching roller of a combing machine used in a spinning process, in particular, an endless apron type top clearer device is provided. In the detaching roller pair, the spun fleece can be correctly introduced into the sliverchin, but it can also be used in the detaching roller pair provided with other clearer devices.

[Prior Art] A sliver chin that is inclined downward is disposed immediately in front of the front detaching roller of a conventional combing machine, and guides and collects while receiving the piecing continuous fleece sent from the pair of detaching rollers. While taking it out as a sliver. A stationary cylindrical clearer or a rocking apron-type clearer device is provided above the detaching roller group to clean the surface of the top detaching roller to prevent wrapping of fibers. FIG. 2 (side sectional schematic view) shows, as an example, a detaching roller portion of a combing machine provided with an apron type clearer device. The front top detaching roller 2 is arranged above the front bottom detaching roller 1. It is driven intermittently in the direction of the arrow. A back bottom detaching roller 1a and a back top detaching roller 2a are disposed behind these rollers, and the top detaching roller 2a is one that reciprocates as shown by a chain line. . As the top detaching roller 2a, there is a top detaching roller 2a that does not reciprocate but sends out a fiber group at a feed ratio of forward and reverse rotation (not shown).

On the other hand, the supply fiber group is gripped by the feed roller 8, the cushion plate 6 and the nippers 7 and is intermittently sent out by a certain length by the retracting operation of the nippers 7 and the rotation of the feed roller 8. Then, the sent-out fiber group is combed by the rotation of the cylinder 3 to which the cylinder comb 4 is attached, and is paired with the back detaching roller pair.
It is joined to the fleece ends gripped by 1a and 2a, drawn in, combed again by the lowering operation of the top comb 9, and sent out from the front detaching roller pair 1 and 2. Immediately before the pair of front detaching rollers 1 and 2, a sliver chin shown as 15 is fixedly arranged, and the sliver chin 15 is integrally formed by bending a bottom plate 15a and side walls 15b on both sides thereof. The fleece sent out from the pair of detaching rollers 1 and 2 is taken out as a sliver while being focused by the sliver chin 15.

On the other hand, an apron clearer device is arranged above the pair of top detaching rollers 2, 2a, and the endless apron 10 is hung on the beam member 12, the clearer roller 11 and the clearer guides 13, 13a, and the clearer is installed. It is intermittently moved in the direction of the arrow by driving the Yala roller. A comb 14a, which is in contact with the apron 10 by its own weight, is supported above the beam 12 by the comb lever 14 to remove the fiber waste attached to the apron 10. And these beam materials 1
2, the clearer roller 11 and the comb lever 14 are attached or locked to both side frames (not shown) so that the entire clearer device is always in contact with the surface of the top detaching roller group 2, 2a. It is configured. There is also 10 below the apron 10 of such a clearer device.
A guard, shown as a, is provided and the guard 10a is provided over the entire width of the clearer device.

By the way, in such a detaching roller device,
As shown in FIG. 2 (a partially enlarged view of FIG. 2), the air contained in the fleece that is sent out as the front detaching roller pair 1 and 2 is rotated is released and the front side of the front detaching roller pair is released. An air flow as shown by the arrow line is formed at. That is, there is a downward airflow formed on the Bottom detaching roller 1 side and an upward airflow formed on the top detaching roller 2 side, and these air streams jump by increasing the nip number of the combing machine (speeding up). Tend to become stronger as it increases. On the other hand, among the airflows generated in this way, most of the descending airflow is provided because the roller-side edge of the bottom plate 15a of the slivertin 15 forms a gap B from the surface of the Bottom detaching roller 1. From the gap B to the lower cavity of the bottom plate 15a, and only slightly to the upper surface side of the bottom plate 15a. However, since the ascending airflow is provided with an apron clearer device so as to cover the entire width of the top detaching roller 2, there is no escape port, and the upward airflow is bent along the guard 10a of the clearer device as indicated by the arrow line. Flowing. Although a gap A is formed between the guard 10a and the top detaching roller 2, the guard 10a
Since a wide cavity is not formed between the apron 10 and the apron 10, the air flow does not flow into this gap A and most of it flows as shown by the arrow line. The fleece F sent out from the pair of front detaching rollers 1 and 2 by such a phenomenon forms a floating portion Fa by an ascending air current, as shown in FIG. 4 (an action diagram similar to FIG. 3). When this raised part Fa falls to the bottom plate 15a, a folded part is formed in the fleece, or a group is formed on the fleece that is evenly aligned due to this rise, or fleece disorder is generated and it does not become a uniform sliver. Sometimes.

[Problems to be Solved by the Invention] Therefore, the present invention is intended to prevent the above-mentioned rise of the fleece so as to obtain a uniform comb sliver even if the speed of the combing machine is increased.

[Means for Solving the Problem] That is, the present invention provides a bottom detaching roller and a top detaching roller in a comber having a sliver chin on the fleece take-out side of a detaching roller pair consisting of a bottom detaching roller and a top detaching roller. A face plate corresponding to the bottom plate of the sliverchin is extended from a position in the vicinity of the contact portion with the touching roller, where a slight gap is provided between the peripheral surface of the top detaching roller and the fleece by the face plate and the sliverchin. It is a combed fleece guide formed with a guide for adjusting the spinning of the.

[Operation] That is, as shown in FIG. 5 (operation explanatory view similar to FIG. 3), the face plate 16 is formed slightly below the front top detaching roller 2 by forming a slight gap with the roller 2. The face plate 16 is arranged at the bottom plate 15
It is provided so as to correspond to a, and is configured to allow the ascending airflow to sufficiently escape from this gap, and even if the fleece floats up, the lift up is regulated low under the face plate 16. is there.

[Embodiment] The present invention will be described below with reference to the drawings, but the drawings show one example of a specific embodiment of the present invention, and the present invention is not limited to the illustrated examples, but is configured in accordance with the spirit of the preceding and following description. The same effect can be obtained even if a part of is changed. Figure 1 (side sectional view)
Shows that the fleece guide according to the present invention is applied to the detaching roller portion provided with the apron type clearer device illustrated in FIG. Ie face plate
The metal plate 16 is formed of metal or a transparent plate, and is attached to and supported by both side walls 15b of the sliverchin 15 so as to be detachable. The face plate 16 is preferably a flat plate whose lower surface is finished smoothly,
If necessary, a downwardly bent corrugation may be formed on the roller side. The face plate may be entirely made of a transparent synthetic resin material, but it is necessary to take measures to remove static electricity so that static electricity generated around the face plate is not charged, and it is necessary to provide a ground wire to ground the machine plate. Although the face plate 16 is provided on the side of the sliver chin 15, the support plate is provided on both side frames of the apron clearer device to support the face plate 16 if necessary, or part of the roller stand. A support arm may be attached to this to support the face plate 16 thereon, and these support and mounting means can be freely selected. Also, the figure shows the one applied to the detaching roller equipped with the apron clearer device, but it is also applicable to the front detaching roller pair provided with the cylindrical clearer device that is fixedly installed over the top detaching rollers 2 and 2a. Can be provided.

[Advantage of the Invention] Since the fleece guide of the comber of the present invention is configured by disposing the face plate above the sliverchin bottom plate in correspondence with the bottom plate, the fleece can be prevented from rising.
It is possible to obtain a uniform Comma Sliver. Further, the structure thereof is extremely simple, and a slight improvement can provide a comber machine having high productivity.
