[Problems to be solved by the device]

 In the conventional devices disclosed in Japanese Patent Laid-Open No. 62-62935 and Japanese Utility Model Laid-Open No. 63-177964, the floating fibers are adsorbed on the filter belt by the suction airflow generated by the rotation of the rotary impeller. , It is carried to the position of the suction nozzle by the filter belt which moves at the same time and collected.

Most of the fibers adsorbed on the filter belt are adsorbed on the front surface of the filter belt, but some of the fibers may pass through the eyes of the filter belt and be bridged to the front and back of the filter belt. In this case, if the fiber is adsorbed on the front side of the filter for a long time, it is recovered by suction with the suction nozzle, but if the fiber is adsorbed while passing through most of the filter belt, it is recovered with the suction nozzle. Instead, it goes around with the belt as it is. These latter fibers are entangled with other fibers when left standing and fixed to the filter belt to reduce the suction airflow generated on the filter surface by the rotation of the rotary impeller.

In order to solve this, there is a method of providing a scraper on the outside of the filter as in Japanese Utility Model Laid-Open No. 63-177964, but (1) the problem that the fibers attached to the inside of the filter cannot be removed, (2) If the scraper is only applied from the outside, the filter is pushed by the scraper and dents inward, and the force of the scraper to contact the filter is weakened accordingly, and the function of removing the fibers deteriorates.

[0007]

[The purpose of the device]

 The purpose of the present invention is to solve the problem that as described above, fly dust adheres to the filter belt and becomes difficult to remove, the amount of air passing through the filter belt decreases, and the dust collecting function of the dust collector deteriorates. To do.

[0008]

[Means for Solving the Problems]

 The present invention is provided with a duct suction airflow generating means, an intake opening, and a filter belt that moves around while covering the opening. The present invention sandwiches the filter belt from both sides of the filter belt. The filter belt cleaning mechanism in the dust collector device of the spinning machine is characterized in that a removing device for removing the dust and the like adsorbed on the filter belt is provided. That is, in the present invention, a scraper (a cotton wool removing means) that comes into contact with the front and back of the dust collector filter belt is provided.

[0009]

In the present invention, since the filter is sandwiched by the scraper from both sides, there is no problem that the scraper is pressed and swelled by one scraper to deteriorate the function of scraping the fiber.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a state in which a suction airflow generation device is installed in a ring spinning machine, and the rotary impeller 1 is rotatably mounted around a horizontal rotary shaft 1a extending in the machine longitudinal direction at the lower rear part of the roller part R. It is arranged over the length. The intake opening corresponding to the roller part R is formed by the dust box 3, the intake opening corresponding to the spindle part S is formed by the dust box 4, and the exhaust opening 6 is formed obliquely downward. The rotary impeller 1 is surrounded by the dust boxes 3 and 4 over the entire length of the machine base. The rotary impeller 1 is set to rotate at all times or in synchronization with the operation of the machine base.

The filter belt 2 is attached to the intake side of the suction airflow generating device configured as described above from the upper surface and both side surfaces.

That is, as shown in FIG. 2, filter belt guide pulleys 2a are rotatably supported around the vertical axis on both the left and right ends of the longitudinal direction of the spinning machine, respectively. The filter belt 2 goes around.

In the cleaning device of the present invention, when the rotary impeller 1 is rotated, the suction airflow F1 is generated in the air intake openings of the dust boxes 3 and 4, and the suction airflow F1 continuously connects the front bottom roller at the time of yarn breakage. The fleece supplied, the fiber debris generated in the roller part R and the spindle part S, and the fiber debris in the air are adsorbed on the filter belt 2 for cleaning. The blowout airflow F2 from the exhaust opening 6 is arranged in the same direction as the airflow F4 generated by the rotation of the chin pulley 5. The blown air flow F2 from the rotary impeller 1 blows off the machine base in the same direction as the air flow F4 generated on the floor by the chin pulley 5, and flows to the downstream parallel spinning machine side.

A large number of the spinning machines shown in FIG. 1 are installed in parallel, and during the working hours of the factory, the exhaust airflow F2 from the suction airflow generator installed in each spinning machine and the chin pulley 5 of each spinning machine are used. The generated airflow F4 generates an airflow in a certain direction in the room, which floats between the machine bases or cleans the fiber debris on the floor. In addition, the airflow supplied from the air conditioning equipment is attracted to the airflow in the room, which is a better condition for air conditioning.

As described above, in the cleaning device of the present invention, the rotation of the rotary impeller 1 causes the suction air flow F1 to be generated in the intake openings of the dust boxes 3 and 4, and when the yarn breaks, the suction air flow F1 is generated. The fleece continuously supplied from the front bottom roller, the fiber debris generated in the roller part R and the spindle part S, and the fiber debris floating in the air are adsorbed on the filter belt 2. The fiber waste adhering to the filter belt 2 is moved to the suction nozzle 7 provided near the filter belt 2 along with the circulation of the filter belt 2 and sucked by the suction nozzle 7.

Most of the fiber debris is removed from the filter belt 2 by the suction nozzle 7, but the fiber debris left on the filter belt 2 without being removed is scraped off from the filter belt 2 by the scraper 8 of the present invention.

As shown in FIGS. 2 and 3, the scraper 8 of the present invention is attached immediately after the suction nozzle 7 so as to come into contact with the filter belt 2 from both sides. That is, in this embodiment, as shown in FIG. 3, plate-shaped scraper blades 8a are attached to the front and back of the filter belt 2 by the brackets 9 by the bolts 10 and the nuts 11, respectively.

After most of the fibers are collected by the suction nozzle, the scraper blade 8 a scrapes off the fibers entwined with the filter belt 2. Since the filter belt 2 is sandwiched by the scraper blades 8a from both sides, there is no problem that the scraper blade 8a is pressed by one scraper blade 8a and swells to reduce the fiber scraping function of the scraper blade 8a on the pressing side.

Another embodiment is shown in FIG. In this embodiment, the scraper wheel 8b made of a brush wheel is in contact with the front and back of the filter belt 2, and the traveling of the filter belt 2 causes the scraper wheel 8b to rotate by friction and wind up the residual fibers of the filter belt 2. The diameter of the scraper wheel 8b gradually increases due to the wound fibers. Therefore, the scraper wheel 8b is constantly pressed against the filter belt 2 with an appropriate force by the spring 12 and the like. The scraper wheel 8b is occasionally cleaned by the operator.

[0020]

[Effect of the device]

 According to the present invention, the fibers entangled in the filter belt can be removed, and stable suction performance of the filter belt can be obtained for a long period of time.
