Abstract
The body of a rotary type clearer is in the form of a shaft-like rotary member having narrow scraping blades (11). And a member of transmitting torque to the shaft-like rotary member having narrow scraping blades is in the form of an elastic roller (12) adapted to be pressed against the small diameter neck portion (15) of the bottom roller. Thereby, a peripheral speed differential is produced between the clearer body and the bottom roller, so that the fly and clearer wastes adhering to the surface of the bottom roller are efficiently removed. The narrow scraping blades assist in the scraping of fly and clearer wastes.
Description
- The present invention relates to improvements in a clearer for bottom rollers in textile machines.
- The draft part of a textile machine, particularly a post-process textile machine, such as a flyer frame or spinning frame is equipped with a rotary clearer having a friction member such as a hair-implanted fabric or napped fabric applied thereto to serve as a scraper for removing fly and clearer wastes.
- In a conventional rotary clearer device, the clearer body is pressed against the fluted surface of the bottom roller of a textile machine under a pressing force provided by a support spring, and the bottom roller and the clearer body are rotated at the same peripheral speed by friction contact, thereby removing the fly and clearer wastes adhering to the fluted surface.
- In the conventional rotary clearer device described above, since the fluted surface of the bottom roller and the clearer body are rotated by contact at the same peripheral speed, the surface of the clearer is not given the peripheral speed differential necessary for scraping fly and clearer wastes; thus, sufficient cleaning effect has not been attained. For this reason, the amount of fly and other fiber wastes adhering to the fluted surface of the bottom roller increases with the passage of operating time, causing sliver breakage, yarn breakage and other troubles.
- To solve the problem described above, the present invention provides a rotary clearer for removing fly and clearer wastes adhering to the surface of a bottom roller, wherein the body of the rotary clearer is formed of a shaft-like rotary member having a narrow scraping blade.
- Further, a member for transmitting torque to the shaft-like rotary member provided with the narrow scraping blade is in the form of an elastic roller adapted to be pressed against the small diameter neck portion of the bottom roller.
- The transmission of torque for rotating the clearer body from the small diameter neck portion of the bottom roller by the pressing of the elastic roller results in producing a predetermined peripheral speed differential between the fluted surface of the bottom roller and the front end portion of the scraping blade of the clearer body, thereby the fly and clearer wastes adhering to the fluted surface is positively scraped. Further, the body of the clearer being formed of the shaft-like rotary member having narrow scraping bladed assists in the scraping of fly and clearer wastes. As a result further enhancing the cleaning effect on the fluted surface of the bottom roller attained by the peripheral speed differential.

- In Figs. 1 and 2, the
reference number 1 denotes a front bottom roller; 2 denotes a second bottom roller; 3 denotes a back bottom roller; 4 denotes an apron; and 5 denotes an apron draft device composed of the apron 5 and a tenser bar 6 and interposed between front andsecond bottom rollers 1 and 2. Thereference number 7 denotes a pneumatic flute disposed forwardly of and below thefront bottom roller 1; 8 denotes a plate spring serving as a rotary support member for the rotaryclearer body 10; and 9 denotes a path of travel for a spun yarn. - The
body 10 of the clearer is molded of an elastically deformable synthetic resin material, e.g., urethane resin. As shown in Figs. 1 and 5, it is formed as a shaft-like rotary member provided with a spiral vane-likenarrow scraping blade 11 forming a predetermined inclinational angle 0 with the axis of thefront bottom roller 1. Thereference number 12 denotes elastic rollers each transmitting torque to thebody 10 of the clearer, each elastic roller being composed of a cylindricalurethane resin layer 13 attractively held on the smalldiameter neck portion 15 of thefront bottom roller 1, and amagnet 14 contained in theurethane resin layer 13. Thebody 10 of the clearer is formed of a highly elastic synthetic resin of high friction coefficient, e.g., urethane resin, and its length and the height of thenarrow scraping blade 11 are controlled so that the front edge line portion of thenarrow scraping blade 11 is urged to abut against thefluted surface 16 of thefront bottom roller 1 over the entire length thereof under elastic pressing force, thereby a peripheral speed differential is produced between a fluted surface of thebottom roller 1 and a front end portion of thenarrow scraping blade 11. The width t of thenarrow scraping blade 11 is preferably not more than 1 mm. As for the narrow scraping blade, besides the spiral vane-like scraping blade 11 shown in Figs. 1 and 5, planar vane-like scraping blades 11A extending parallel with the axis of thefront bottom roller 1 as shown in Figs. 2 and 4. only one narrow scraping blade may be used, but in both cases of the spiral vane-like scraping blade 11 and the planar vane-like scraping blade 11A, a plurality may be fixed around the shaft-like rotary member at a predetermined angular spacing. For example, thebody 10 of the clearer shown in Fig. 4A has a single planar vane-like scraping blade 11A fixed thereto to extend axially, and in thebody 10 of the clearer shown in Fig. 4B, three planar vane-like scraping blades 11A are fixed thereto at an angular spacing of 120° to extend axially. Further, in thebody 10 of the clearer shown in Fig. 4C, two planar vane-like scraping blades 11A are fixed thereto at an angular spacing of 180° to extend axially. Alternatively, as shown in Figs. 6A and 6B, planar vane-like scraping blades 11A may be separately prepared in the form of planar plates, mounted at their roots on ashaft 21 by using set plates 11B and fixed in position by set bushings 11C. The number ofscraping blades body 10 of the clearer is constructed of a shaft-like rotary member having two or more spiral vane-like scraping blades 11, these spiral vane-like scraping blades 11 form a multiple thread construction around the shaft-like rotary member. - While the
elastic roller 12 shown in Figs. 1 and 5 is formed of a concentric fit structure comprising a cylindricalurethane resin layer 13 and amagnet 14, theelastic roller 12 shown in Figs. 2 and 4 is formed of only a cylindricalurethane resin layer 13 of large friction coefficient. In the case where the diameter of thefluted surface 16 of thefront bottom roller 1 is 25 mm and the diameter of the smalldiameter neck portion 15 is 23 mm, in order to produce a predetermined peripheral speed differential between thefluted surface 16 of thefront bottom roller 1 and thescraping blade elastic roller 12 shown in Figs. 1 and 5 is so dimensioned that the cylindricalurethane resin layer 13 has an outer diameter of 21 mm. In this case, the radius of the spiral vane-like scraping blade 11 and planar vane-like scraping blade 11A measured from the center of theelastic roller 12 is about 11 mm so that the front end edge line portion of the scraping blade can be pressed against thefluted surface 16 of thefront bottom roller 1 for cleaning while maintaining the peripheral speed differential as it is being elastically deformed. - In the case where the
elastic roller 12 is formed of aurethane resin layer 13 and amagnet 14 mounted therein, a torque transmission system with little slippage can be formed between thebottom roller 1 and theelastic roller 12 by utilizing the attractive force of themagnet 14 acting through theurethane resin layer 13. On the other hand, in the case where theelastic roller 12 is composed of aurethane resin layer 13 alone as shown in Figs. 2 and 4, aplate spring 8 is used as a support member for theelastic roller 12. - In the
rotary clearer 20 shown in Figs. 1 and 5, ashaft 21 made of aluminum or stainless steel which is suitable for preventing decrease of the magnetic force of themagnet 14 is used as a rotary support member for theclearer body 10 andelastic roller 12. In contrast, in the rotary clearer 20 shown in Figs. 2 and 4, since theelastic roller 12 composed of theurethane resin layer 13 is used, ashaft 21 made of iron is used. In each case, the end of theshaft 21 is formed with a male thread 21a, and theclearer body 10,elastic roller 12,first collar 18, andsecond collar 22 are fitted on theshaft 21 in a predetermined order and are clamped and fixed in position by using anend nut 17 of synthetic resin formed with a female thread 17a adapted for threaded engagement with the male thread 21a, and around nut 19 formed with a female thread 19a. - In the embodiment shown Fig. 1, a
front bottom roller 1 havingfluted surfaces 16 for six spindles is rotatably supported between unillustrated roller stands, and corresponding thereto sixclearer bodies 10 each having spiral vane-like blade 11 are opposed to thefluted surfaces 16. In this case, to prevent relative axial positional shift between theclearer body 10 and thefluted surface 16, it is desirable that the threeclearer bodies 10 positioned at the left-hand side between the roller stands have their spiral vane-like scraping blades 11 turned right-handed and the three clearer bodies (not shown) positioned at the right-hand side between the roller stands have their spiral vane-like scraping blades turned left-handed. - As can be understood from the description given above, torque for the
clearer body 10 is transmitted from the smalldiameter neck portion 15 of thefront bottom roller 1 by theelastic roller 12 pressed thereagainst, whereby a predetermined peripheral speed differential is produced between thefluted surface 16 of thefront bottom roller 1 and the front end portion of thescraping blade clearer body 10 and thefluted surface 16 is strongly rubbed. Therefore, the fiber wastes such as fly and clearer wastes adhering to thefluted surface 16 is positively scraped by the rubbing of thescraping blade clearer body 10 of shaft-like rotary member havingnarrow scraping blades fluted surfaces 16 of thefront bottom roller 1 in a concentrated load fashion. For this reason, in contrast to the use of a conventional rotary clearer device in the form of a round roller, a higher cleaning effect is produced with less power consumption. - Further, by using an
elastic roller 12 of urethane resin with high friction coefficient as a member for transmitting torque to theclearer body 10, the attracting function of themagnet 14 is improved. - In the above embodiment, an example in which the
rotary clearer 20 has been mounted on thefront bottom roller 1 of a spinning frame having an apron type draft mechanism has been described; however, as indicated by thereference number 10A in Fig. 2, the clearer device of the invention may also be mounted is such a manner as to form common cleaning means to act on both theback roller 3 and theapron 4 wrapped around the second bottom roller 2. The use of the device of the invention is not limited to spinning frames but it may also be used as a rotary type clearer 20 for post-process textile machines such as winders and flyer frames. - The use of the device of the invention adapted to produce a predetermined peripheral speed differential between the clearer body and the bottom roller efficiently removes fly and clearer wastes adhering to the surface of the bottom roller. The fly and clearer wastes scraped from the surface of the bottom roller are slung by the spiral vane-like scraping blades or planar vane-like scraping blades; thus, the fluted surface of the bottom roller is kept clean without applying special cleaning thereto. As a result, entry of fiber wastes into the path of travel of the yarn being spun is prevented, minimizing the occurrence of yarn breakage and knotted yarn formation.
