As shown in FIG. 5 disclosed in Japanese Patent Publication No. 183, a suction duct 42 is provided behind the roller beam 41 along the machine longitudinal direction.
And a blower pipe 44 disposed at the front end of the flyer rail 43 and an intake pipe 46 communicating with the suction duct 42 behind the draft device 45. A device has been proposed and implemented for sucking and removing cotton dust or cotton dust scraped off from the clear cloth 47 by the suction duct 42 by the action of the suction airflow of the pipe 46. In general, the suction duct 42 has a filter box 48 connected to one end thereof as shown in FIG. 6, and the suction duct 42 is rotated by driving a fan 50 provided in a room partitioned by a filter 49.
A suction airflow toward the filter box 48 is generated inside,
The cotton dust sucked into the suction duct 42 is collected in the filter box 48.

(Problems to be solved by the invention) However, in the device using the suction duct 42, the fan 50 needs to be constantly driven during operation of the machine base, and the power consumption thereof is extremely large at about 3 KW. There is a problem that the ratio is large compared to the power consumption of the main motor for the main body of the stand being 9 to 11 KW.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning device for a roving machine, which can reliably remove dust and the like on the upper surfaces of the flyer rail and the roller beam and consumes less power.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, a belt conveyor is provided on the rear side of the roller beam along the machine longitudinal direction, and a flyer rail is provided at the front end of the flyer rail. And a blower tube that blows out an air stream flowing toward the belt conveyor side on the upper surface of the roller beam, and a cover for preventing the passage of cotton flies on the side opposite to the blower tube across the belt conveyor. At the end of the stand, there was provided a removing device for removing fly dust and the like accumulated on the belt conveyor.

(Operation) In the device of the present invention, the air flow blown out from the air blow tube provided at the front end of the flyer rail flows toward the belt conveyor on the flyer rail and the upper surface of the roller beam,
The fly dust to be deposited on the flyer rail or the roller beam is carried onto the belt conveyor by the air flow and is deposited on the belt conveyor. The waste cotton continuously scraped from the clear cloth and dropped on the roller beam is also carried on the belt conveyor by the action of the air flow. A part of the cotton dust blown off by the airflow tries to pass on the belt conveyor, but this cotton dust is received by the cover and is reliably placed on the belt conveyor. Then, the fly dust accumulated on the belt conveyor is conveyed to the machine base end by the movement of the belt conveyor, and is removed from the belt conveyor by the removing device provided at the machine base end.

(Embodiment 1) A first embodiment embodying the present invention will be described below with reference to FIGS. Behind the roller beam 2 on which the draft device 1 is installed, a belt conveyor 4 is provided over the entire length in the machine longitudinal direction via a support bracket 3 fixed to the roller beam 2. The belt 5 of the belt conveyor 4 is a driving roller 6 arranged on the out end side of the machine base,
It is wound between driven rollers (not shown) arranged on the gear end side, and its upper surface is the upper surface of the roller beam 2 by a plurality of guide rollers 7 (only one is shown) arranged between both rollers. It is designed to move at almost the same height position. A chain wheel 9 is fitted and fixed to one end of a rotary shaft 8 of the drive roller 6 so as to be integrally rotatable, and a chain 12 is wound between the chain wheel 9 and the chain wheel 11 fitted and fixed to the output shaft 10a of the motor 10. It is hung.

On the other hand, a blower pipe 16 connected to a blower duct (not shown) via a pipe 15 is provided above the front end of the flyer rail 14.
Is provided over the entire length of the flyer rail 14, and the intake pipe 16 is provided with a large number (1) of air nozzles 16a for blowing out an air flow flowing toward the belt conveyor 4 on the upper surfaces of the flyer rail 14 and the roller beam 2. (Only one is shown). In addition, a cover 13 is fixed to the support bracket 3 along the belt conveyor 4 in order to prevent fly dust or the like carried by the action of the air flow blown from the blower tube 16 from passing through the belt conveyor 4. .

As shown in FIG. 2, a guide groove 17a extending vertically is provided at a position corresponding to the one-end drive roller 6 of the support bracket 3.
A pair of slants 17 (only one of which is shown) are provided upright, and a take-up roller 18 having a cloth around which fibers or the like are easily attached is wound around the sland 17, and a support shaft 18a protruding from both ends thereof is provided. It is movably supported along the guide groove 17a.

Next, the operation of the device configured as described above will be described. During the operation of the roving frame, cotton wool or the like generated from the roller part of the draft device 1 or the roving yarn connected to the flyer top 19 from the roller part falls on the upper surface of the flyer rail 14. Further, the cotton swabs scraped off from the clearer cloth 20 as the roller part cleaning means provided in the draft device 1 falls on the roller beam 2. Flyer rail 1
No. 4 blowing nozzle 16a of the blowing pipe 16 provided at the front end
The air is constantly blown from the above so as to generate an air flow flowing toward the belt conveyor 4 on the upper surfaces of the flyer rail 14 and the roller beam 2. Therefore, the cotton wool, waste cotton, and the like dropped on the upper surfaces of the flyer rail 14 and the roller beam 2 are carried onto the belt 5 of the belt conveyor 4 by the action of the air flow. When the strength of the air flow is strong, the cotton dust and the like may pass over the belt 5, but in this embodiment, since the cover 13 is provided over the entire length of the belt conveyor 4, it is carried by the air flow. The cotton dust and the like are surely deposited on the belt 5.

The belt 5 is driven at a constant low speed by the motor 10,
The cotton wool accumulated on the belt 5 is gradually taken up by the take-up roller 18.
Move to the position corresponding to. The take-up roller 18 is rotated with the rotation of the belt 5 due to the frictional force with the belt 5, and the wind cotton or the like on the belt 5 is stripped from the belt 5 and wound around the roller. Therefore, the fly dust and the like carried to the position corresponding to the take-up roller 18 by the movement of the belt 5 is taken up by the take-up roller 18 and removed from the belt 5. The take-up roller 18 gradually moves upward along the guide groove 17a as the amount of cotton fly or the like taken up by the take-up roller 18 increases. After the cotton wool or the like is wound to some extent on the winding roller 18, the wound cotton wool or the like is collected by the operator.

Since the moving speed of the belt 5 is extremely low, the electric power used by the motor 10 may be about 40 W, which is extremely smaller than the electric power used for driving the fan for generating the suction airflow in the suction duct of the conventional apparatus of 3 KW. .

Second Embodiment Next, a second embodiment will be described with reference to FIGS. In this embodiment, a comb for scraping is provided in place of the take-up roller 18 as a removing device for removing the fly cotton and the like accumulated on the belt 5, and the wiped cotton and the like are removed along the spinning machine stand. This is a great difference from the apparatus of the above-mentioned embodiment in that the traveling cleaner is moved automatically to recover the collected material. In the second embodiment as well, in the same manner as the first embodiment, in order to prevent the cotton dust and the like carried by the action of the air flow from passing over the belt 5, a cover (illustration is made along the belt 5 is provided. Is omitted) is fixed. The traveling cleaner 21 reciprocates along the machine longitudinal direction to blow away the cotton dust accumulated on the bobbin rails of the spinning machine stand and suck and remove the cotton dust accumulated on the floor surface. The cotton box 22 is stopped at a position corresponding to the suction nozzle 23, and the cotton wool collected during one reciprocation is delivered to the cotton box 22.

A pair of brackets 24 (only one of which is shown) is fixed in parallel on the lower surface of the support bracket 3 near the end thereof so as to be movable along an elongated hole 24a formed in the bracket 24. A support shaft 25 is supported. The spindle 25 has a comb 26 at one end and a weight 2 at the other end.
A pair of levers 28 to which 7 is fixed (only one is shown)
By the action of the weight 27, the tip of the comb 26 is rotatably supported while being constantly biased by the belt 5. The other end of a drive lever 31 having a cam follower 30 engaging with an eccentric cam 29 integrally rotatably fixed to the output shaft 10a of the motor 10 at one end is rotatably connected to the substantially central portion of the support shaft 25. ing. A shooter 32 is provided on the outer side of the bracket 24 to collect the cotton wool scraped off from the belt 5 by the comb 26. One of the shooters 32 is opened to allow movement of the drive lever 28 and the drive lever 31, and the traveling cleaner 21 is provided at a position corresponding to the suction nozzle 23 of the cotton collecting box 22 in the discharge port 33 provided at the lower portion. The other end of a flexible tube 35, which has a discharge port 34 connected to a suction nozzle 21a provided in the traveling cleaner 21 when stopped, is connected to the other end. The nozzle 21a of the traveling cleaner 21 is configured such that the suction action of the cotton collection box 22 acts on the flexible tube 35 when the discharge port 34 of the flexible tube 35 is connected.

Next, the operation of the device configured as described above will be described. By driving the motor 10, the belt 5 is moved in the direction of the arrow in FIG. 3, the eccentric cam 29 is rotated, and the drive lever 31 is reciprocally moved, so that the lever 28 supported by the support shaft 25.
Are reciprocated in synchronization with the drive lever 31. Lever 28
The reciprocating motion of the reciprocating motion causes the comb 26 attached to the tip thereof to reciprocate while being pressed against the belt 5. On the other hand, as in the case of the apparatus of the above-described embodiment, the fly dust and the like carried on the belt 5 by the action of the air flow blown out from the air blow nozzle 16a and deposited on the belt 5 are moved to the machine base end as the belt 5 moves. When it moves and reaches a position corresponding to the comb 26, it is scraped off by the comb 26 and collected by the shooter 32. The cotton wool and the like deposited and deposited on the belt 5 are moved to a position corresponding to the comb 26 while being adhered to the belt 5 even after the belt 5 passes through the revolving portion corresponding to the drive roller 6. On the other hand, the traveling cleaner 21 reciprocates along the spinning machine stand and temporarily stops when it reaches a position corresponding to the suction nozzle 23 of the cotton collection box 22. At this time, the nozzle 21
The discharge port 34 of the flexible tube 35 is connected to a, the suction work of the suction nozzle 23 of the cotton collection box 22 also acts on the flexible tube 35, and the cotton swabs collected in the shooter 32 pass through the flexible tube 35. It is automatically collected in the cotton collection box 22. That is, in the apparatus of this embodiment, the cotton wool and the like removed from the belt 5 is automatically collected via the traveling cleaner 21.

The present invention is not limited to the above-described embodiments. For example, instead of constantly driving the belt 5 of the belt conveyor 4 at a constant speed, the belt 5 may be intermittently driven at predetermined intervals, or the second embodiment may be used. The cotton wool scraped off by the comb 26 in the apparatus may be collected in a cotton collection box provided below the shooter 32.

(Effects of the Invention) As described in detail above, according to the present invention, the fly dust on the upper surface of the flyer rail and the roller beam can be reliably removed, and the power consumption is greatly reduced as compared with the device using the conventional suction duct. It has an excellent effect that it can.
