Description

Description: TECHNICAL FIELD The present invention relates to a clearer device for a draft roller of a spinning machine provided with a drawing device, and more particularly to a method in which a cut piece of a clearer material is reduced in length between roller stands. On the formed clearer support frame, a pad clearer whose leading edge is projected and held is attached so as to press against the peripheral surface of the draft roller, and the clearer is positively moved in the front-rear direction or along the peripheral surface of the draft roller. To facilitate the cleaning effect and handling operation.

[Related Art] As a clearer device for a bottom draft roller, a cut piece of a clearer material made of leather, synthetic leather, rubber, synthetic rubber, or a laminated nonwoven fabric is held in a clearer support frame formed to a length between roller stands. There is known a clearer device in which one edge of a clearer material is protruded from the clearer material and abuts against the peripheral surface of the draft roller. The applicant has already proposed the structure, mounting and supporting means of such a pad clearer (Japanese Patent Application No.
177438, Jitsuin 61-115848).

By the way, it has been found that such a clearer device can provide a remarkable cleaning effect as compared with the conventional rotary type clearer device.However, if the clearer device is used continuously for a long time, the clearer debris accumulates on the contact edge of the clearer material. The drawback is that it has been pointed out. From these, a means for intermittently moving the contact contact portion of the clearer material was developed, or a means for intermittently opening the contact contact portion was studied. However, it is difficult to positively remove the deposited clearer debris simply by swinging the pad-type clearer device, and if the abutting edge of the clearer material is intermittently strongly pressed or weakened or separated. It turned out to be effective. Also, with the conventional clearer mounting and supporting device, the clearer attachment / detachment operation was not easy. Therefore, it has been desired to provide a mounting support device that is easy to handle and easy to maintain.

[Problems to be Solved by the Invention] According to the present invention, when the above-described pad clearer is provided opposite to the draft roller, the peripheral surface of the draft roller or the draft roller is maintained while maintaining the clearer support frame in a substantially constant relationship with the draft roller. Actively intermittently move in the direction away from the peripheral surface,
In addition, the attachment support means is intended to positively move the clearer support frame along a locus of a predetermined sliding groove in order to facilitate the mounting / removal operation of the clearer support frame from the front side.

[Means for Solving the Problems] A mounting device for a pad clearer according to the present invention is characterized in that a cut piece of a clearer material made of rubber, synthetic rubber, or the like is provided on each end of a clearer supporting frame formed to a length between roller stands. In a mounting device for a pad clearer in which an edge is protruded and held to face a draft roller, sliding members are arranged at both ends of a clearer support frame, and the sliding member is concentric or eccentric with a draft roller shaft. The slide bracket is loosely fitted to the support bracket attached to the roller stand, and the clearer support frame is fitted with an elastic plate for holding the position and an elastic plate for operation. The front ends of the working rings fitted to the rear draft rollers are opposed to each other, so that the clearer support frame can be moved in the front-rear direction without tilting. And the summary.

[Operation and Examples] Hereinafter, the present invention will be described in detail with reference to the drawings. However, the drawings show specific examples of the present invention, and the present invention is not limited to the illustrated examples. The present invention can be similarly implemented by changing a part of the configuration or changing a part of the design along the line. FIG. 1 (side view) shows a case where the mounting device of the pat clearer of the present invention is independently used for a front bomb draft roller constituting a drawing device of a ring spinning machine. It can be used in the same way for draft rollers of other spinning machinery and can also be mounted on other draft rollers of the same drawing device, respectively, and if necessary these clearer devices can be linked to one another to form one clearer. It is also possible to move the support frame simultaneously with other clearer support frames.

In FIG. 1, 1 is a front bottom draft roller, 2 is a bottom apron roller, 3 is a third bottom roller, 4 is a back bottom roller (these rollers are hereinafter referred to as draft rollers), and these draft rollers are shown. At the upper part, a front top roller 1a, a top apron roller 2a, a third top roller 3a and a back top roller 4a are arranged, and these draft rollers are respectively supported by roller stands 6, 6, and the top roller group is a weighting arm. 7 to be loaded on the draft roller. Although not shown in the figure, a suction duct of a pneumatic clearer is often provided on the front lower side (the left side in the figure) of the front draft roller 1 in many cases. The mounting device of the pat clearer of the present invention is shown as 5, which is provided on the front bottom roller 1 alone. Although the bottom apron device provided on the draft roller 2 is of the short apron type, it can be installed on another long apron type in the same manner. That is, the mounting device 5 according to the present invention is provided for each interval (staff) between the roller stands 6 and 6, and the clearer device includes a plurality of weights (4 to 8) between the staffs on a clearer support frame 8 formed to the length of the staff. (The figure shows six weights.) The clearer material 9 is attached to each of the spinning portions.

On the other hand, as shown in FIG. 2 (a front view in the direction of arrow A in FIG. 1), the draft roller 1 is formed by a flute portion 1b and a cylindrical portion 1c having a slightly smaller diameter than the flute portion 1b. All devices are placed on this flute 1b. Therefore, the cylindrical portion 1c of the draft roller forms a space on the outer periphery. On the other hand, as shown in FIGS. 2 and 4 (a partially enlarged front view on the left side of FIG. 2), the pad clearer device is a clearer support frame 8 in which a metal plate is folded in two in accordance with the length between staff members. Is used to form a projecting window hole of the clearer material on the bending side to make the clearer material 9 protrude. And as the clearer material 9, the ears 9a on both sides
Is formed to restrict the protruding length so that both edges can be exchanged and used. Reference numeral 9b denotes a mooring stopper for the clearer material 9, which is formed by bending an elastic steel plate as shown in FIG. 5 (schematic drawing for explanation of the structure). On the open side, and a bent portion of the tip is projected inward from a window hole 8 a formed in one side of the support frame 8 to fix the clearer material 9.

The essential part of the present invention lies in the mounting device 5 of the pad clearer device thus formed, and the mounting device 5 is shown in FIG. 3 (an enlarged sectional view in the direction of the arrow along the cutting line III-III in FIG. 2). As shown in FIG. 1 (a partially enlarged view) and FIG. 4, both ends of the clearer support frame 8 are supported by a support bracket 10 attached to the roller stand 6. And support bracket 10
As shown in FIG. 5, a mounting portion 10a to be fitted to the front thin portion 6a of the roller stand 6 and a protrusion formed on both sides of the roller stand 6 with the roller stand 6 interposed therebetween, and a sliding groove is formed in the protrusion.
11 are formed respectively. 10b is a mounting screw. The sliding groove 11 is formed concentrically with the axis of the draft roller 1 as shown in FIG. 3 and is open at the front thereof, but is formed eccentrically or linearly as described later. You may.

On the other hand, in mounting the clearer support frame 8 in the sliding groove 11 of the support bracket 10, a sliding member 12 that moves along the sliding groove 11 as shown in FIG. An anchor portion of the clearer support frame 8 is formed on one of the side walls. That is, FIG. 5 shows the receiving seat on the side wall of the sliding member 12.
The receiving seat 13 fits and supports the lower ends of both ends of the clearer support frame 8. FIG. 6 (drawing) shows a supporting member 14 formed on the side wall of the sliding member 12 in place of the receiving seat 13.
The support portion 14 is fitted into the bending gap of the clearer support frame 8 and supports the support frame 8 at its top.
The sliding member 12, the receiving seat 13, and the support portion 14
It is recommended to use a synthetic resin material as an integral part. The roller bracket 6 is used as the support bracket 10.
The support bracket 15 may be mounted on the back side of the slide portion of the roller stand 6 as shown in FIG. 7 (side view), or the slide groove 11 may be mounted on the front side. Is shown as an open groove, but it may be formed as a non-open groove as shown in FIG. 8 (operational side view). In addition, these sliding grooves 11 show the movement trajectory of the sliding member 12 as a curved line, but as shown in FIG. 9 (side view schematically), the sliding groove 11 extends in a direction orthogonal to the axis of the draft roller and with the roller group. It may be a parallel linear sliding groove 11b.

On the other hand, as shown in FIG. 2 and FIG. 3, the clearer support frame 8 attached to the support brackets 10 and 15 via the sliding member 12 has elastic plates 16 for position holding on both sides thereof at the center. The operation elastic plates 17 are fixed to the respective members. Although the means for attaching these elastic plates 16 and 17 is not shown, a window hole is formed and inserted in the bent end side of the queerer support frame 8, and a wedge piece is inserted from the open side of the bottom to fasten, Alternatively, the holding plate is screwed onto the support frame and clamped, for example, to be fixed. The position holding elastic plate 16 is moored to the front side of the ten server 19 whose front end bent portion is stretched between the roller stands, and the operating elastic plate 17 is bent at its front end in a hook shape to form the rear draft roller 2. It is located on the lower side. The position holding elastic plate 16 may be a bifurcated tip and fitted under the ten server 19, or may be inserted under the ten server 19 and moored. You may. That is, as shown in FIG. 3, the clearer support frame 8 is configured to hold the position where the clearer material 9 contacts the peripheral surface of the draft roller 1 with an appropriate pressure by the elastic plate 16. The elastic plate material contacting the front side of the cylindrical portion 1c of the draft roller 1 may be formed integrally with the position holding elastic plate 16, or these elastic plate materials may be further attached to the clearer support frame 8.

On the other hand, an operating ring indicated by 18 is fitted to the cylindrical portion of the rear draft roller 2, and a hook 18a is formed at one end of the operating ring 18. And this hook 18a is draft roller 2
Is engaged with the hook-shaped portion of the operating elastic plate 17 to pull the operating elastic plate 17 rearward, and slide the clearer support frame 8 rearward against the position holding elastic plate 16. . When the engagement of the hooks 18a is released, the clearer support frame returns by the restoring force of the elastic plate 16. FIG. 8 shows these operations, in which the sliding groove formed in the support bracket 15 is an arc locus centered on the point Oa eccentric with the axis O of the draft roller 1, The selection of the amount of eccentricity can be freely selected by changing the mounting position of the support bracket 15 by sliding. That is, the clearer support frame 8 moves from the dashed line position to the dashed position when the operating elastic plate 17 is pulled back to the dotted line position, and returns to the dashed line position again when the engagement is released. Since this movement follows the sliding groove trajectory without tilting the clearer support frame 8 by the sliding groove 11 and the sliding member 12, the clearer material 9 attached to the clearer support frame 8 is restored as shown by a dotted line. Then, the contact pressure with the draft roller 1 is reduced or slightly separated to remove accumulated clearer debris, and the change in the contact pressure improves the cleaning effect.

[Effect of the Invention] Since the mounting device for the pad clearer of the present invention is configured as described above, the pad clearer device can be moved without tilting with respect to the draft roller, and the contact pressure of the clearer material can be changed. Therefore, a clearer having an extremely excellent cleaning effect can be obtained. In addition, the attaching means does not complicate the draft portion, maintenance and management are easy, and attachment / detachment operation of the clearer device is easy.
