[Industrial applications]

 BACKGROUND OF THE INVENTION The present invention relates to a plate-shaped pad material used in a clearing device, which is provided in a spinning machine provided with a drafting device so as to correspond to a draft roller.

[0002]

[Prior Art]

 As a clearer device for a draft roller, it is well known that a cleaning pad material such as leather, synthetic leather, rubber, synthetic rubber or laminated non-woven fabric is brought into contact with the peripheral surface of the draft roller. Further, these cleaning pad materials are bent and held by bending, and the curved surface side is pressed against the draft roller, or the edges of these cleaning pad materials (hereinafter simply referred to as pad materials) are brought into contact with the draft roller. There are things to hold. Of these, the latter one in which the edge of the pad material is brought into contact with the draft roller is recommended from the viewpoint of cleaning effect.

On the other hand, various means have been proposed and put to practical use as means for holding and holding these pad materials against the draft roller, but such a clearer device must be cleaned regularly or at any time. Since it has to be installed, it is configured to be detachable from the draft roller. That is, such a clearer device is generally constructed by attaching a pad material facing one spinning staff (between roller stands) to one support member, and this pad attachment support member is used for the roller stand or the roller. The support device attached via the stand is detachably supported.

By the way, in such a clearer device in which the edge of the pad material is brought into contact with the peripheral surface of the draft roller, the edge of the individual pad material is brought into full contact with the flut formed on the peripheral surface of the roller. The support members must be securely held between the staffs, and each pad material must be uniformly held by the support members. On the other hand, in a clearer device that uses such a pad material, a press plate is generally used to attach and hold the pad material to the support member, and each pad material is sandwiched and supported by the support member. .. Therefore, when attaching the pad material to the support member, the pressing plate is tightened while aligning the tip edges of the pad material using a special restriction jig. Also, when replacing any one of the pad materials, all the pad materials are not evenly contacted with the draft roller unless the positional relationship between the support member and the tip edge of the protruding pad is fixedly attached to the other pad material. Therefore, such a clearer device requires time and effort to assemble it.

FIG. 8 and FIG. 9 (both of which are assembly development exploded views) show a part of a clearer device configured by attaching a conventional pad material, and the cut pad material 17 as described above is shown in FIG. In this example, the support frame 16 is sandwiched and supported by the holding plate 18. The support frame 16 and the holding plate 18 are formed to have a length for each staff, and the support frame 16 has curved edges 16a, 16a at its front and rear edges. In addition, a notch 16b for projecting a pad is formed on the edge 16a on the side where the pad material 17 is projected. When assembling, the countersunk screw 19 is used to screw into the screw hole 19b of the holding plate 18 through the hole 19a formed in the support frame and the long hole 17a formed in the pad to tighten the pad material. The tip edges (right side in the figure) of 17 are aligned. The pressing plate 18 has a width that can be accommodated in the curved edges 16a, 16a of the support frame 16.

Further, in the example of FIG. 9, the tip side of the pad material 17 is attached by inclining to one side, and the pad protruding side of the support frame 20 is formed as an inclined bending portion 20b, and a bending edge 20a is formed on the rear side. When the pad material 17 is sandwiched, the guide plate 21 is interposed, and the tip 21a of the inner plate 21 is formed with the same inclination and short as the bent portion 20b of the support frame, and the tip of the pad material 17 is tightened by tightening the holding plate 22. The edge is projected so as to be inclined in substantially the same direction as the bent portion 20b. When tightening, a round head screw 23 is used to press through the hole 23a of the support frame 20, the long hole 17a of the pad, and the hole 23b of the guide plate. It is fastened by being screwed into the screw hole 23c of the plate 22. However, in all of these cases, the tip edge of the pad material 17 is required to be projected in a straight line and a fixed length from the support frame when tightening, and a special jig is required. In addition, screw heads and screws are projected on the support frame, and steps are formed on the side of the support frame where the pads are projected to promote the accumulation of fly cotton.

【Example】

 The present invention will be described in detail below with reference to the drawings. However, the drawings show an example of specific embodiments of the present invention, and the present invention is not limited to these illustrated examples, but is in accordance with the gist of the preceding and the following. Even if a part of the configuration is changed, the same operation can be performed.

The pad material is made of leather, synthetic leather, rubber, synthetic rubber, or laminated nonwoven fabric, preferably synthetic rubber material having excellent abrasion resistance and static eliminability. (a), (b), (c), ears 13a, 13a are formed on both side edges thereof as shown in FIG. 5, and the distance from the front side root portion of the ears 13a to the tip edge 13b and the ears 13a The distance from the root portion on the rear surface side to the rear edge 13c is almost the same. Further, this distance regulates the protruding length of the pad 13. As shown in FIG. 3, the width dimension excluding the ears 13a corresponds to the length of the flute portion 5c of the draft roller 5, and the cutout window 12a of the support frame 12 to be described later allows only this portion to pass through the ears 13a. (Break portion in FIG. 3).

FIG. 2 (side sectional view) shows an example of a drafting device provided with the pad material 13 of the present invention, and the drafting device shows only a main part. That is, the clearer device 1 is shown as being opposed to the back bot mroller 5 of the draft device. In addition to this, it can be applied to the front bot m roller 3 or the bot m apron 4b as well, and is required. Depending on the situation, it is possible to install a pair of draft rollers. In the illustrated draft device, the apron draft section is formed by the front bot mroller 3, the front top roller 3a, the apron roller 4, the cradle roller 4a, and the aprons 4b and 4c hung on them, and the back bot m roller 5 and A representative example is a backtop roller 5a, 6 is a trumpet guide attached to the traverse bar 7, 8 and 8a are rotary clearers which are opposed to the front roller pair 3 and 3a, and 9 is a rotary clearer. It is a suction cleaner nozzle. FIG. 3 (side view) shows a part in the direction of the arrow in FIG. 2. In these figures, the support frame 12 of the clearer device 1 is a metal plate with a thickness of about 1 mm cut into the length dimension between the staffs. Is folded into two and the gap between the folds is such that the pad material 13 can be easily inserted. On the bent side, cutout windows 12a are formed so as to correspond to the flute portions 5c of the draft roller 5, respectively. In forming the cutout window 12a, it is recommended to perform pre-punching before bending the support frame, but it may be bent and then cut. In addition, the bent outer peripheral surface is circular as shown in FIGS. 2 and 4 (partially sketched view of the main part fractured), or only the corners are circular as shown in FIG. 5 (assembled explanatory sketch). May be

When attaching the pad material 13 to the support frame 12, as shown by an arrow in FIG. 5, the pad material 13 is inserted from the opening end side of the support frame 12 so as to protrude from the cutout window 12a, and the ears 13a are bent respectively. The position is regulated by making contact with the inner surface. Reference numeral 15 indicates a stopper for supporting the pad material 13 inserted in the support frame 12. The stopper 15 is formed by bending a cut elastic steel plate into a U shape as shown in FIG. The upper side) is formed long and an inner bent portion 15a is formed at the tip thereof, and the bent portion 15a is formed as a notch portion 15b in which the central portion is cut to the side surface, and the other side surface is a tongue piece portion. 15c. On the other hand, the stopper 15 is disposed on the opening end side of the support frame 12 and serves to support the pad material 13 in the support frame 12. The figure shows a groove into which the bent portion 15a of the stopper 15 is inserted. The hole 14 is formed in advance on either side of the support frame 12, and a step portion 14a (FIG. 5) is formed on the opening side edge of the slot hole 14.

When assembling, the pad material 13 is inserted into the support frame 12 as described above, and then the stopper 15 is spread out as shown by the arrow while the bent portion 15a of the bent portion 15a is first formed on the opening end side of the support frame 12. , 15a are inserted into and engaged with the slots 14, and then the tongue portion 15c is fitted on the outside of the other side bent portion. The pad material 13 is sandwiched and held by the support frame 12 only by this fitting, but the bent portion 15a of the stopper 15 is formed to be longer than the thickness of the metal plate material of the support frame 12 so that the bent portion 15a The pad material 13 can be directly pressed by the tip of the. The cutout portion 15b of the bent portion 15a is made to coincide with the stepped portion 14a of the slot 14 so as to serve as a hook portion of the lever type bar tool when the stopper 15 is detached from the support frame 12. is there.

In holding the clearer thus constructed against the draft roller, a suitable mounting bracket can be provided on the roller stand to support the clearer. However, the bracket 10 as shown in FIGS. 2 and 3 is used. Is preferred. Immediately, the bracket 10 is attached while sandwiching the roller stand 2 with the tightening screw 11 of the slide metal 5b of the draft roller while maintaining the positional relationship with the draft roller 5. A partly open vertical groove 10a which is tightly fitted and receives and supports the support frame 12 at the bottom of the groove, and the pad material 13 bends in contact with the draft roller. Conveniently, the contact portions 10b and 10c formed in the above are supported and held.

Further, as shown in FIG. 6 (partially cutaway side view), the draft roller is configured such that the frutes of the frute portion are inclined with respect to each other. For such a draft roller 5c, a pad material is used. It is preferable that the leading edge of 13 also match this inclination. Therefore, in the pad material according to the present invention, if the tip edge line is a pad 13d whose inclination lines are not parallel to the root portions of the ear portions 13a, the inclination adjustment work becomes unnecessary. FIG. 7 (side sectional view) shows a clearer device applied to the front roller 3 of the draft device, and a bracket 10d having a specially inclined bracket shape, and if necessary, a supporting frame insertion vertical groove for this bracket 10d. Even when 10a is arranged in a substantially horizontal state, the clearer is stably supported by the repulsive force, as described above, because the pad material 13 is bent by contact with the roller. The pad material of the present invention is not limited to the above example, and has at least one abutting tip line (a portion that linearly abuts the draft roller), and the ears 13a, 13a are formed on both sides thereof. Then, the entire pad material may have any shape as long as it regulates the protruding length of the contact tip line.

[Effect of the device]

 Since the present invention is constructed in this manner, it is extremely easy to attach and replace the pad material, and moreover, when attaching the pad material, it is possible to perform accurate position regulation simply by inserting. Also, since this pad material can be easily replaced, its tip edge can be used as a working edge, and if the tip edge becomes worn, it can be turned over and replaced, and it has two tip edges. In the case of objects, they can be used as they are by changing the position of the other edge. The replacement time can be extremely short. Furthermore, since a plurality of pad materials can be evenly contacted with the roller, the cleaning effect is improved and the accumulation of cotton wool is eliminated. Further, there is an effect that the configuration is simple and can be provided at low cost.
