Description

[Detailed Description of the Invention] Object of the Invention (Industrial Application Field) The present invention relates to a roller part cleaning device for a spinning machine.
More specifically, the present invention relates to a cleaning device for the top clear floss portion of the roller part.

(Prior art) In general, spinning machines such as roving frames and fine spinning machines are equipped with two or more sets of rollers with different surface speeds, and the difference in surface speed is used to sequentially thin the fiber bundle, a so-called O-rad draft. type draft devices are widely used. In this type of drafting device, in order to obtain a spun yarn of constant quality, it is necessary to maintain a constant regulating effect on the fibers passing between the upper and lower rollers, and it is necessary to keep the peripheral surface of the rollers clean at all times. As shown in FIG. 6, a conventional roller cleaning device includes top rollers 1a to 4a and bottom roller 1b.
The top clear rear floss 5 and the bottom clear rear floss 6 circulate while being pressed against the surface of the fiber Iff regulating portion of ~4b.
There are some that have . In the apparatus using this Clear Lafloss 5.6 (A), it is preferable to remove the adhesion surface of each Clear Lafloss 5.6 so that a clean part is always pressed against each roller. A scraper 7.8 is disposed that comes into contact with the upper surface of the loss 5 and the lower surface of the bottom clear rough floss 6, respectively, and serves to scrape off the adhered cotton on each of the clear rough floss 5.6. The adhered cotton is scraped off by a scraper 8, and the scraped cotton 9 is moved by its own weight to a roller beam 10.
The suction duct 11 falls upward and passes through the suction port 11a formed in the suction duct 11 extending along the longitudinal direction of the machine.
automatically removed by suction. On the other hand, the adhered cotton on the top clear rough cloth 5 is scraped off by the scraper 7, and the scraped cotton 9 accumulates on the front surface of the scraper 7. Then, the scraped cotton 9 is periodically removed manually.

However, since the top clear luff cloth 5 is usually placed higher than the head of the worker, it is difficult to remove the scraped cotton 9 manually. In order to overcome this inconvenience, a mobile dedicated cleaning device was installed on the roving frame frame, but since the dedicated cleaning device was installed, the entire device became larger and more expensive.

(Problems to be Solved by the Invention) The present invention solves the troublesome manual work and the problems that equipping the spinning machine itself with a cleaning device increases the size and cost of the device.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, an automatic tube changer that moves along the longitudinal direction of one spinning machine is equipped with a cleaning device. The cleaning device consists of a cotton collection box that is divided into an intake chamber and a cotton collection chamber by a net, and an intake fan is installed in the intake chamber, and a cotton collection box that collects cotton using a top clear cloth cleaning member of the roller part of the spinning machine. and a suction vibrator, one end of which is connected to the cotton collecting chamber.

(Function) The device of the present invention automatically changes pipes when the tip of the suction vibrator extending from the cotton collecting chamber communicating with the suction chamber is placed at a position corresponding to the top clear rough cloth cleaning member of the roller part of the spinning machine. It moves along the longitudinal direction of the spinning machine table together with the spinning machine table, and sequentially sucks up the cotton removed from the top clear cloth of each roller part arranged on the spinning machine table and stores it in the cotton collection chamber.

(Embodiment) An embodiment embodying the present invention will be described below with reference to FIGS. 1 to 3. Note that the configurations of the roller part, clear rough cloth, etc. disposed on the roving frame frame 12 are the same as those in the conventional device, and are given the same reference numerals and explanations thereof will be omitted.

Rail 1 laid along the longitudinal direction of the roving frame frame 12
A support bracket 15 is fixed to the upper part of the tube changer 14, which moves intermittently along the roving frame 3 and performs tube change work, at approximately the center on the opposite side from the roving frame frame 12. Support bracket 15
A cotton collection box 19 partitioned into an intake chamber 17 and a cotton collection chamber 18 by a net 16 is disposed above, and an intake fan 21 driven by a motor 20 is disposed within the intake chamber 17. In addition, the cotton collection room 18 has a door 2 with a handle 22a.
2 is provided.

On the side of the upper roving frame frame 12 of the tube changer 14, a hydraulically operated rotary cylinder 23 is used to establish a standby position parallel to the longitudinal direction of the tube changer 14 shown in FIG. A support arm 26 is pivotally arranged in an operating position corresponding to the opening 25a of the cover 25 of the part 24,
It is rotatably disposed at its base end. A suction vibrator 27 that sucks the scraped cotton 9 scraped off by the scraper 7 as a member for cleaning the top clear rough cloth of the roller part 24 has its base end connected to the cotton collection chamber 18 and is connected to the support arm 26. A flexible portion 27a is provided at a portion corresponding to the base end, and a nozzle 27a attached to the tip of the suction vibrator 27 is connected to the tip of the support arm 26 and fixed to the support arm 26 by a support piece 29. The distal end side of the flexible portion 27a is configured to be movable integrally with the support arm 26.

Next, the operation of the apparatus configured as described above will be explained. Now, when the roving frame is operated to fully wind the roving around the bobbin to form a full bobbin 30, the operation of the frame is stopped and the bobbin rail 31 is lowered to the doffing position.

Then, the pipe changing machine 14 moves along the rails 13 and pipe changing work is performed.

Before the pipe changing machine 14 starts moving along the rail 13 for pipe changing work, the rotary cylinder 23 is activated and the support arm 26 is rotated approximately 90 degrees from the standby position to the working position, and the suction vibrator 27 is rotated approximately 90 degrees. As the support arm 26 rotates, the nozzle 28 is moved to a position that can correspond to the opening 25a of the cover 25.

Next, the motor 20 is driven, the suction fan 21 is driven to rotate, and the suction pipe 27 receives suction from the nozzle 28 into the collection chamber 1.
A suction airflow is generated which is guided to the suction chamber 17 via the air.

In this state, the pipe changer 14 is moved to the Rover frame 12 for pipe change work.
As the suction vibrator 27 moves sequentially from one end to the other, the nozzle 28 of the suction vibrator 27 sequentially corresponds to the opening 25a provided in the cover 25, and the top clear luff cloth 5 is scraped off by the scraper 7. The scraping cotton 9 accumulated on the front surface is successively removed by suction. The cotton sucked from the nozzle 28 passes through the suction vibrator 27 and is collected into the cotton collection chamber 18. After the tube changer 14 has moved to the other end of the roving frame i 12, the rotary cylinder 23 is activated and the suction vibrator 27 is moved to the standby position together with the support arm 26. The cotton accumulated in the cotton collecting chamber 18 is manually taken out by an operator by opening the door 22 during the standby time of the pipe changing machine 14 until the next pipe changing operation is required.

d. This invention is not limited to the above-mentioned embodiment. For example, as shown in FIG. A discharge port 34 may be provided with a door 33 that is automatically opened and closed in response to the connection and disconnection of the connection pipe 32 of (1). In this case, the connecting pipe 32
The cotton in the cotton collection chamber 18 is automatically discharged to the cotton collection duct. Alternatively, the suction vibrator 27 may be configured to be rotated directly by the rotary cylinder 23 without being supported by the support arm 26, or a motor may be used instead of the rotary cylinder 23 to rotate the suction vibrator 27 or the support arm 26.
or rotate the suction vibrator 27 so that its tip is covered 25.
It may be arranged in a fixed state at a predetermined position that can correspond to the opening 25a.

Further, the tube changing machine may be provided with a roller part or a blower for cleaning the upper surface of the flyer rail. Furthermore, the intake chamber 17
An outlet of an exhaust pipe (not shown) that guides the exhaust air is provided in a part of the mechanism of the tube changer 114 where it is particularly necessary to prevent the accumulation of fluff, and the outlet of the exhaust pipe (not shown) that guides the exhaust air from the cotton collection box 19 is used to change the tube. The machine itself may also be cleaned.

Further, in the above embodiments, the present invention is embodied in a tube changing machine for a roving frame, but it may also be embodied in a tube changing machine for a fine spinning machine.

Effects of the Invention As described in detail above, according to the present invention, the scraped cotton scraped from the top clear rough cloth is automatically suctioned and removed, which eliminates the laborious work of the operator and eliminates the scraping process. The cleaning device that suctions and removes the cotton is equipped on the tube changer that runs along the spinning machine table, so there is no need for a drive mechanism to move the cleaning device along the spinning machine table, making the device more compact. Moreover, the manufacturing cost is low. Furthermore, cleaning is performed every time a spinning machine is doffed, which matches the normal cleaning cycle, and since a single tube changer can doff multiple spinning machines in sequence, it has the excellent effect of increasing operating efficiency as a cleaning device. play.
