CONSTITUTION:A cleaning pad 2 in an almost horizontal state is brought into contact with a draft roller 6, the bent outer surface of the pad is slanted downward, the tip edge of the pad is kept along the flute of the draft roller and the bent part of the pad is vibrated. A pad attaching beam material 3 receives resistance force of the arrow C and tilting force of the arrow B by the bent contact of the pad 2. Both the ends of the beam material are inserted into an open type groove supported by three points to regulate revolution in the arrow D direction opposing to the tilting force in the arrow B direction and attaching and detaching of the beam material is readily carried out.

Description

[Detailed description of the invention] [Field of application in business a] A clearer device installed opposite to a draft roller constituting a drafting section of a spinning machine provided with a drafting device, the cleaning member being made of a padding material and When this is attached to a beam material and brought into contact with a draft roller, it automatically brushes off peeled fibers and dust caused by cleaning to prevent them from accumulating, and also holds the pad securely in position and makes it easy to attach and detach the clearer. It is designed to be easy to perform.

[Prior Art] As a draft roller clearer device, one in which a cleaning material such as synthetic leather, rubber, synthetic rubber, or laminated nonwoven fabric is brought into contact with the peripheral surface of the draft roller is well known. In addition, when placing these cleaning materials opposite to the draft roller, it is necessary to bend the cleaning material into a curved shape and hold it so that this curved surface comes into surface contact with the draft roller, or to cut the cleaning material as described above and cut the edge of the cleaning material. It is also well known that there is a device in which a draft roller is brought into contact with a draft roller. On the other hand, when considering the cleaning effect, in the former surface contact type, peeled fiber waste and dust tend to adhere and accumulate on the front or rear side of the clearer material, and this scum must be removed, which poses management problems. . In addition, since the contact force is relatively weak, it is not expected to be very effective in removing impurities such as honeydew that enter the grooves of the roller. On the other hand, in the latter case, a pad type clearer in which the tI4 edge of the cleaning material is brought into contact with the draft roller surface, the contact pressure per unit of the roller contact surface is high, so the cleaning effect is good.
Moreover, relatively little cotton sludge is deposited on the edge of the pad, so this pad-type clearer has come into widespread use recently.

However, even in this pad-type clearer, a cotton layer tends to adhere to the contact area between the pad and the draft roller, and this layer gradually accumulates and becomes a lump that is taken up again by the draft roller or falls and becomes the spun yarn. It may become twisted and cause a fraudulent system to be created. In addition, in such a pad-type clearer, the cleaning pad for one staff is generally attached to a single piece or a beam made of one piece with the contact side tip protruding, and this beam is urged toward the draft roller. The support means is intended to fix the beam in a fixed position, and it is time-consuming to attach and detach the beam. It takes. Moreover, this attachment/detachment is done behind the draft device out of sight of the operator, and is actually done by hand. For pad-type clearers, the deposited cotton layer is automatically brushed off to eliminate the deposited cotton layer, and the beams that attach and support the pad can be easily attached and removed by hand, and the pad can be held in position accurately. It is requested that the device be a device.

[Problems to be Solved by the Invention] Therefore, the present invention provides a means for immediately brushing off the cotton sludge peeled off from the draft roller in a pad-type clearer device to keep the tip of the pad clean at all times. The purpose of the present invention is to provide a support device in which attachment and detachment of a pad-type clearer device can be done extremely easily by groping, and the cleaning pad can be held in an accurate position.

[Means for Solving the Problems] That is, in the present invention, the pad of the pad type clearer device is conventionally arranged so as to be in contact with the lower part of the draft roller in the direction of rotation, and the beam material supporting this pad is made of a spring. In many cases, the rollers are biased towards the roller side or are fixedly arranged. That is, FIG. 3 (explanatory sectional view) shows an example of a conventional pad-type clearer device, in which the pad 2 is opposed to the front roller 6 at the lower part of the roller in the direction of rotation (arrow) (at a 45-degree angle in the figure). angle). Therefore, the cotton slag 10 peeled off from the roller 6 is likely to accumulate on the curved outer surface of the pad 2, and the larger the angle of arrangement, the closer the curved outer surface becomes to horizontal, further increasing the amount of cotton slag 10 deposited. Further, these accumulated cotton slags gradually hang down and adhere to the top surface or side wall surface of the beam material 3. Therefore, in the present invention, FIG. 4 (explanatory sectional view)
As shown in the figure, the pad 2 is brought into contact with the axis of the draft roller 6 from a substantially horizontal position, and the beam material 3 that attaches and supports the pad 2 is attached at three points by utilizing the pad's bending resistance. It is constructed so that it can be easily inserted and supported in the insertion groove supported by the holder.

[Function] That is, by bringing the cleaning pad into contact with the draft roller in a substantially horizontal state, the curved outer surface of the pad is directed downward, and the tip edge of the pad is actively aligned with the flute formed on the draft roller to form a crest of the flute. The bent part of the pad is moved by the trough and the cotton sludge that has peeled off at the tip edge is immediately brushed off. As shown in Fig. 5 (cross-sectional diagram for explaining the action), the pad-attached beam material that comes into contact with each other in this way is moved in the direction of arrow B by the reaction force shown by arrow C due to the bending contact of pad 2 and by the contact pressure caused by the rotation of the roller. Since it is tilted to
Both ends of the beam are inserted into open grooves supported at three points that oppose each other and regulate the direction of the arrow, thereby ensuring reliable support and facilitating attachment and detachment of the beam.

[Example] The present invention will be described in detail below based on the drawings. However, the drawings show an example of the implementation of the present invention, and the present invention is not limited to the illustrated example. The same implementation is possible even if the configuration of is changed. FIG. 1 (side sectional view) is a schematic view showing an example of a draft device to which the present invention is applied, and FIG. 2 (bottom view) shows the direction to the arrow in FIG. 1.

In these figures, the pad-type clearer device 1 of the present invention is most effective when installed opposite the front bottom roller 6, but it can also be applied to a third bottom roller or a back bottom roller that has a slow rotation speed due to the roller 6. It can be applied not only to draft rollers but also to gripping and take-out rollers as long as they are rollers that form flutes. - As the cleaning pad 2 used in the strength tree invention, cleaning materials that have been used in the past or will be developed in the future can be used, but the preferred material is antistatic synthetic rubber material. A stiff material with relatively strong bending elasticity is preferable, and this elasticity may be maintained by the thickness of the pad material. On the other hand, as a beam material 3 for attaching and supporting such a pad 2, various devices have been proposed in the past, such as Japanese Utility Model Publication No. 54-24535 and Japanese Utility Model Publication No. 35-27939, but the beam material 3 used in the present invention is Any material can be used as long as it allows the pad 2 to protrude and hold uniformly. FIGS. 1, 2, and 8 (corresponding to FIG. 2 showing other configuration examples of the present invention) show the beam material 3 made of a metal plate bent into a U-shape. A pad protrusion hole 3a is formed on the end side to allow the pad 2 to protrude, and the pad 2 has ears 2a, 2a on both sides thereof.The length of the pad 2 to be projected is regulated by a hole 1, and the pad is inserted from the bottom side of the bent opening. Reference numeral 2 shows a beam member which is clamped and fixed by lips 9 so as to close the insertion side and sandwich the folded walls on both sides, but a beam member having another structure may be used. Furthermore, the third
In Figures to Figures 5, this beam 3 is replaced by two beam plates [3,
3a shows the pad 2 sandwiched between the pads 2 and 3a. Also the first
The figure shows only the bottom side of the apron drafting device, which is composed of a bottom apron roller 7, a tensile bar 7a, and an apron 7b that is passed over them, in order to understand the embodiment of the present invention. In the pad clearer 2 arranged in this way, as explained in FIG. 4 above,
The tip edge 2c of the pad 2 is provided along the flute 6a of the trough/roller 6, and the bending fluctuates in accordance with the protrusions and troughs of the flute 6a. Since the front roller 6 rotates at a relatively high speed, this fluctuation causes vibration.
Since the peeled cotton layer is immediately released downward, it can be brushed off downward. Therefore, in a case tilted as shown in Fig. 3, even if vibrations occur as described above, cotton slag tends to accumulate on the curved surface, and this surface and the grooves of the flute tend to pinch the peeled cotton sinter. It is not good for a person to leave.

On the other hand, in the pad-type clearer provided in this manner, the beam members 3 tend to move in the directions of arrows C and B, respectively, and can be held in position by restricting these movements.

However, in order to restrict and hold these, it is also possible to screw both ends of the beam material 3 to appropriate brackets, or form a fitting part or an insertion groove to attach it, but these attachment methods do not work. Fixing means are required. Especially beam material 3
In order to support the machine in a horizontal state and to allow it to be attached and detached in a part out of sight of the worker, it is necessary to insert the support device so that it rests on the shelf and maintain the position by this insertion. is necessary. The support device 4 of the present invention satisfies these requirements. That is, the support device 4
As shown in the figure and FIG. 2, the intermediate stands provided on the roller stand 5, excluding the roller stands on both sides of the draft line, are comprised of brackets that support one end of the beams 3, 3 on both sides, respectively. is the set screw 8 of the bearing member 8 that supports the bottom apron device.
Attach the bottom side 4e formed on the support device 4 to the roller stand 5 using a. The beam support groove 4a formed in the support device 4 is a groove whose lower front part is open as shown in FIG. , a bottom support part 4d is formed on the back side, and an abutment part 4c is formed on the lower rear side. Therefore, beam material 3
As shown by chain lines on both ends thereof, the support groove 48 can be inserted from the lower front part of the tip of the support groove 48 while tilting regardless of the roller 6 formed wider than the thickness of the beam material 3. Then, the pad 2 is brought into contact with the bottom support part 4d and the contact part 4C.
When the beam 3 is pushed up so as to be brought into pressure contact with the roller 6, the beam 3 comes into close contact with the bottom support portion 4d due to the bending repulsion force of the pad 2, and the friction force of the pad 2 causes the beam 3 to contact the joint portion 4b and the contact portion 4C. held in close position. On the other hand, the beam 3 can be easily removed by pushing down the front of the beam 3 with both hands against the bending force of the pad 2. 7th
The figure (side view) shows another example of the structure of the support device of the present invention, in which the joint part 4b is formed with a joint part 4e that also makes contact with a part of the front top surface of the beam material 3. Removal can be performed in the same manner as described above. Note that some draft rollers 6 have flutes inclined to each other as shown in FIG. 8, and for such a roller flute 6b, the tip edge of the pad 2 is provided along this inclination. In FIG. 8, one end of the clamping support clip 9 of the pad 2 is bent and engaged with the slot 3b formed in the side wall, and the tip of this bent piece is made to reach the pad 2. Although support is shown, any suitable lip device may be used.

[Effects of the Invention] Since the pad-type clearer of the present invention is constructed as described above, the cleaned cotton layer is extremely less likely to adhere and accumulate on the pad and the supporting beam material, thereby improving the cleaning effect. Moreover, the support device has a simple structure and can reliably hold the position, and the pad attachment beam can be easily attached and detached, so that it can be operated by hand.
