Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a roller part cleaning device for a spinning machine, and more particularly to a cleaning device for a top clear rear cross section of a roller part.

(Prior art) In general, spinning machines such as roving frames and spinning frames are equipped with two or more sets of rollers with different surface speeds, and the so-called roller draft system uses the difference in surface speed to sequentially thin the fiber bundle. 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 is provided with a top clear lacrosse 5 and a bottom clear lacrosse 6 that circulate while being pressed against the surfaces of the fiber regulating portions of the top rollers 1a to 4a and bottom rollers 1b to 4b. There is. In an apparatus using the clear lacrosses 5, 6, it is preferable that the adhesion surface of each clear lacrosse 5, 6 be removed so that a clean portion is always pressed against each roller. For this purpose, scrapers 7 and 8 are provided which come into contact with the upper surface of the top clear rear cloth 5 and the lower surface of the bottom clear rear cloth 6, respectively, and serve to scrape off the adhered cotton on the respective clear rear cloths 5 and 6. And bottom clear lacrosse 6
The adhered cotton is scraped off by the scraper 8, and the scraped cotton 9 falls onto the roller beam 10 under its own weight, and is sucked through the suction port 11a formed in the suction duct 11 extending along the longitudinal direction of the machine. It is automatically suctioned and removed into the duct 11. On the other hand, the cotton adhered to the top clear rear 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 cloth 5 is usually located higher than the head of the operator, it is difficult to remove the scraped cotton 9 manually. In order to overcome this inconvenience, some machines have installed a mobile dedicated cleaning device on the roving frame, but since the dedicated cleaning device is installed, the entire device becomes 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 the spinning machine stand is equipped with a cleaning device. The cleaning device is divided into an intake chamber and a cotton collection chamber by a net, and a cotton collection box in which an intake fan is installed in the intake chamber, and a top clear cloth cleaning member of the roller part of the spinning machine to collect the collected cotton. It consists of a suction pipe whose one end is connected to the cotton collection chamber for suction. The tip of the suction pipe is movably arranged between an operating position corresponding to the top clearing cloth of the roller part and a standby position on the automatic pipe changer.

(Function) The device of the present invention is operated by an automatic pipe changer when the tip of the suction pipe extending from the cotton collecting chamber communicating with the suction chamber is placed at a position corresponding to the top clear cloth cleaning member of the roller part of the spinning machine. At the same time, it moves along the longitudinal direction of the spinning machine stand, and sequentially suctions the cotton removed from the top clear cloth of each roller part arranged on the spinning machine stand, and stores it in the cotton collection chamber.

After the pipe changing machine performs the pipe changing operation, the suction pipe is moved to a standby position on the automatic pipe changing machine so that its tip does not interfere with the running of the pipe changing machine.

(Example) Examples 1 to 3 which embody this invention will be described below.
This will be explained according to the diagram. Note that the configurations of the roller part, clear lacrosse, etc. disposed on the roving frame frame 12 are the same as those in the conventional apparatus, and are given the same reference numerals and explanations thereof will be omitted.

On the upper part of the tube changer 14, which moves intermittently along the rails 13 laid along the longitudinal direction of the roving frame frame 12 and performs tube change work, there is a section approximately in the center on the opposite side of the roving frame frame 12. A support bracket 15 is fixedly attached to the support bracket 15. A cotton collection box 19 is provided on the support bracket 15 and is divided into an intake chamber 17 and a cotton collection chamber 18 by a net 16, and an intake fan 21 driven by a motor 20 is provided in the intake chamber 17. ing. Further, the cotton collection chamber 18 is provided with a door 22 with a handle 22a.

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 rotatably arranged at its base end, and is rotatably arranged in an operating position corresponding to the opening 25a of the cover 25 of the part 24. roller part 2
A suction pipe 27 for suctioning the scraped cotton 9 scraped by the scraper 7 as a top clear cloth cleaning member of No. 4 has its base end connected to the cotton collection chamber 18 and the base end of the support arm 26. A flexible portion 27a is provided at a corresponding portion, and a nozzle 28 attached to the tip of the suction pipe 27 is connected to the tip of the support arm 26, and the support piece 2
9 is fixed to the support arm 26, and 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 rough system is completely wound onto the bobbin by the operation of the roving frame and a full bobbin 30 is formed, the operation of the machine is stopped and the bobbin rail 31 is
descends to the doffing position. And pipe change machine 14
moves along the rail 13 and pipe replacement 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 nozzle 28 of the suction pipe 27 is rotated by the cover 25 as the support arm 26 is rotated.
is moved to a position that can correspond to the opening 25a. Next, the motor 20 is driven to rotate the suction fan 21, and a suction airflow is generated in the suction pipe 27 that is sucked from the nozzle 28 and guided to the suction chamber 17 via the cotton collecting chamber 18.

In this state, when the pipe changing machine 14 sequentially moves from one end of the roving frame frame 12 to the other end for pipe changing work, the nozzle 28 of the suction pipe 27
The scraping cotton 9 that is scraped off from the top clearing cloth 5 by the scraper 7 and accumulated on the front surface of the scraper 7 is successively suctioned away. The cotton sucked from the nozzle 28 is collected into the cotton collection chamber 18 via the suction pipe 27. After the tube changer 14 has moved to the other end of the roving frame frame 12, the rotary cylinder 23 is activated and the suction pipe 27 is moved to the standby position together with the support arm 26. The cotton accumulated in the cotton collection 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.

Note that the present invention is not limited to the above-mentioned embodiments, and for example, as shown in FIGS. 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). With this configuration, the cotton in the cotton collection chamber 18 is automatically discharged to the cotton collection duct by connection with the connection pipe 32. In addition, the suction pipe 27 is connected to the support arm 2.
Rotary cylinder 2 directly without supporting with 6
3, or use a motor instead of the rotary cylinder 23 to rotate the support arm 26.
Alternatively, the suction pipe 27 may be configured to rotate. 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 outlet of the exhaust pipe (not shown) that guides the exhaust air from the intake chamber 17 is provided in a part of the mechanism of the pipe changer 14 where it is particularly necessary to prevent the accumulation of fluff, and the The pipe changer itself may be cleaned using the exhaust air.

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-kuriyara cloth is automatically suctioned and removed, which eliminates the complicated work of the operator, and also Since the cleaning device that suctions and removes water is installed on the tube changer that runs along the spinning machine table, there is no need for a drive mechanism to move the cleaning device along the spinning machine table, and the device can be made more compact. Manufacturing costs are low. Furthermore, cleaning is performed every time the spinning machine is doffed, which matches the normal cleaning cycle, and the pipe changing machine sequentially performs complex doffing of the spinning machine, which has the excellent effect of increasing operating efficiency as a cleaning device. play.
Also, since the top clear rear cross of the roller part is located at the back of the spinning machine stand, it is necessary to insert the suction pipe into the back of the spinning machine stand, and the suction pipe should protrude in a direction perpendicular to the direction of movement of the pipe changing machine. It is necessary to do so. This state poses a problem when the automatic tube changer moves between spinning machine stands, but in the present invention, the suction pipe is movably arranged in a standby position above the automatic tube changer. It has become possible to mount the suction pipe on the automatic pipe changer without interfering with the running of the pipe changer.
