Description

[Detailed Description of the Invention] Technical Field The present invention relates to a device that automatically collects waste cotton etc. from endless clearers installed at the upper and lower parts of the roller part of a roving frame using suction airflow. .

Prior art and its problems A conventional roving frame is equipped with an endless clearer device at the upper and lower parts of the roller part, and the lower endless clearer, which has a relatively large amount of attached cotton, removes the scraped cotton. However, since the upper endless clearer, which has a relatively small amount of attached cotton, is not equipped with a new-machine clearer, the scraped cotton has to be removed manually. I was removing it by twisting it. However, in recent years, there has been a demand for roving machines with a new automatic clearer attached to the upper endless clearer in order to save labor in cleaning work, and in response to this demand, a cleaning device for the roving machine was developed. 57−
It has already been disclosed in Publication No. 59878. However, the cleaning device for a roving frame disclosed in Japanese Utility Model Application Publication No. 57-59878 connects a fixed pipe to a mounting pipe equipped with an upper air intake opening, and connects the fixed pipe to a single pipe placed behind the roller beam. A moving pipe that is moved in the longitudinal direction of the machine body via a belt is provided between the intake pipe and a lower intake opening is attached to the belt, and the moving pipe and the lower intake opening are connected to the machine via the belt. By moving the table in the longitudinal direction, the upper intake opening and the lower intake opening alternately communicate with one intake pipe to alternately suck the scraped waste cotton, and the moving pipe and the lower intake opening alternately communicate with one intake pipe. Since the belt with the lower intake opening is placed below the supply sliver entering the roller part, fly fluff tends to accumulate on the belt, and if the accumulated fluff is left unattended, it will damage the belt and the guide section. A clogging occurs between the belts and the belt slips, causing malfunction. For this reason, the fluff accumulated on this long belt must be manually removed periodically, which is not necessarily satisfactory as an apparatus whose main purpose is to save labor in cleaning work.

Outline and Purpose In view of the shortcomings of the prior art, this draft has been developed to include an upper duct that connects multiple sets of upper nozzles for sucking the scraped waste from the upper endless clearer, and a suction unit for sucking the scraped waste from the lower endless clearer. The lower duct, which connects multiple sets of lower nozzles for suctioning water, is connected to a shared pneumatic box, and a suction switching valve is installed on the pneumatic box side of the upper and lower ducts to alternately switch the suction of both ducts. It is characterized by the fact that it automatically collects scraped cotton etc. from the endless clearers installed at the upper and lower parts of the roller part by suction airflow, and there is no need to increase the capacity of the newer motor. A pneumatic box using a small-capacity motor can be used, and it has a simple structure with few moving parts.There are no problems caused by clogging of air lint as with conventional devices, and the suction can be changed over a long period of time. It is an object of the present invention to provide a device for collecting waste cotton scraped off from a clearing machine in a roving frame, which can be carried out stably and eliminate manual cleaning work.

Embodiment Hereinafter, the present invention will be explained in detail with reference to an embodiment shown in the drawings. In Fig. 1, 1 is a roller beam, 2 is a roller stand arranged at a predetermined interval (usually every 4 spindles) in the longitudinal direction of the roller beam 1, and on this roller stand 2 is a 4-wire roller part.

As shown in FIG. 2, the lower duct 23 fixedly installed at the rear of the roller beam 1 and the upper duct 18 fixedly installed above the rear side of the roller part have their respective open end ends at the machine base end. A common pneumatic box 24 installed in the room is inserted into the cotton collecting chamber 25 from the side and top sides, and its opening end surfaces 23a and 18a are opposed at right angles, and between the opposing opening end surfaces 23a and 18a, A suction switching valve 26 is provided to alternately switch the suction of both ducts 23 and 18. This suction switching valve 26
As shown in FIG. 3, a shielding plate 28 that alternately closes the opening of the upper duct 18 and the opening of the lower duct 23 is connected to a swing shaft 27 supported in the width direction of the duct. A swing shaft 27 with the shield plate 28 connected thereto
is connected to a small motor 31 via a worm wheel 29 and a worm 30, and a switch dog 32 is rotatably attached to the end of the swing shaft 27, and the swing position of the shield plate 28 is set at the swing end of the switch dog 32. Two limit switches 33, 34 are provided for detection, and these two limit switches 33, 34
is electrically connected to the small motor 32 via a relay, timer, etc. (not shown), and the small motor 32 alternately repeats normal rotation and reverse rotation at fixed time intervals. Accordingly, the shielding plate 28 alternately closes the openings of the two ducts 18 and 23, and the suction of both ducts is automatically switched.

In the above-described embodiment configured in this way, as shown in the figure, the shielding plate 28 of the suction switching valve 26 is pressed against the open end surface 18a of the upper duct 18 to close the opening, and the other end of the lower duct 23 is closed. When the roving machine starts operating with the opening communicating with the cotton collecting chamber 25 of the pneumatic box 24, the pneumatic motor 35 and the fan 36 are started at the same time, and the lower duct 23, which is in communication with the cotton collecting chamber 25 of the pneumatic box 24, starts operating. A suction airflow is generated in the lower nozzle 22 and the comb 15 is drawn from the lower surface of the lower endless clearer 14.
Scraped waste cotton and top rail 21
The lower nozzle 22 continuously sucks the fluff carried by the blowing air from the side to the roller beam 1 side for a certain period of time, and the sucked scraped fluff and fluff are stored in the lower procedure duct 23. The cotton is carried by the suction airflow into the cotton collecting chamber 25 of the pneumatic box 24 and collected one after another. On the other hand, the upper duct 18 and the upper nozzle 1

Since the shielding plate 28 of No. 6 blocks the suction airflow, the cotton adhering to the upper endless clearing roller 12 is scraped off by the comb 13 and is removed from the upper surface of the upper endless clearing roller 12. is maintained. Then, after a certain period of time has passed since startup,
A timer (not shown) operates and the suction switching valve 26
The small motor 31 rotates in reverse, and the shielding plate 28 that was blocking the opening of the upper duct 18 rotates clockwise from the solid line position in FIG. When the section is closed, the switch dog 32 pushes the limit switch 34 and the small motor 31 is stopped. As a result, the opening of the upper duct 18 is opened and the pneumatic box 24 is opened.
The opening of the lower duct 23, which was in communication with the cotton collection chamber 25 and was open, is closed by the shielding plate 28 of the suction switching valve 26. As a result, the suction by the lower duct 23 and lower nozzle 22 is interrupted,
In turn, a suction airflow is generated in the upper duct 18, the flexible pipe 19, and the upper nozzle 17, and the scraped waste cotton scraped by the comb 13 from the upper surface of the upper endless clearer 12 is transferred to the upper nozzle 1.
