Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device on a roller part and a flyer support rail in a roving frame.

In the roller part of a roving frame, the surfaces of the fiber regulating parts of the upper and lower rollers in the fiber passage section are conventionally cleaned using roller cleaning devices, such as clear rough cloth that circulates in pressure contact with the rollers, or scratchers made of flexible materials. Let it work,
The scraped waste cotton was disposed of using suction airflow.

However, a large amount of fluff accumulates on the roller neck part other than the fiber passing part, and on the container, guide, collector, etc. which are the fiber passing part but are not cleaned, and the support rail that supports the flyer on the upper part accumulates. Fly fluff generated by the rotation and vibration of the roving thread passing above it tends to accumulate on the upper surface, and especially at the flyer top where the roving thread is introduced, a large amount of fluff is deposited on the upper surface because the roving thread contacts the flyer top while rotating. This caused a defect in that fly fluff was generated and accumulated, and this fly fluff sometimes formed into clumps and was carried into the passing roving, impairing the quality of the wound product.

In order to eliminate this defect, a blow pipe is conventionally provided between each fiber part of the upper and lower rollers to guide the generated fluff to the front of the roller part, and the blow pipe is located in front of the roller part, and the fluff is deposited on the upper surface. A cleaning device in which a blow pipe and an intake pipe are arranged at the front end of a flyer support rail and the rear end of a roller beam, respectively, and the air flow generated by the action of both pipes is made to flow to the upper surface of the support rail and roller beam. (Unexamined Japanese Patent Publication No. 4
No. 9-2937) was proposed, but this air flow causes the waste scraped off the comb installed on the underside of the Clear Lough Floss to float to the surface, so it is not sucked into the intake pipe but wrapped around the comb drive unit. Another problem arises in that the comb drive absorbs the oil, thereby reducing the smooth operation of the comb drive.

The purpose of this invention is to install an air control plate in front of the comb to guide the air flow injected from the blowpipe installed at the front end of the flyer support rail to the intake pipe installed at the rear end of the roller beam. By installing a cleaning device on the roller part and flyer support rail of a roving frame, it is possible to eliminate the flotation and scattering of waste cotton fed from the comb, which is a conventional defect, and to ensure smooth operation of the comb drive unit, etc. Our goal is to provide the following.

Hereinafter, an embodiment embodying the present invention will be explained with reference to the drawings.

supported.

A comb 28 is fixed to a mounting plate 29 having an inverted U-shaped cross section and welded to the upper surface of the support fitting 26, and when the operating arm 15 is reciprocated back and forth, the connecting rod 21. Support metal fittings 24.
26 and the mounting plate 29, it can be swung back and forth to remove waste adhered to the clear luff cloth 13.

Reference numeral 30 indicates the front surface of an L-shaped mounting bracket 31 fixed to the lower surface of the support bracket 24 with the screws 25, and the mounting plate 29.
It is an air control plate welded to the front of the roller beam 1, and its lower end is bent slightly backward to direct the airflow flowing from the front to the roller beam 1.
It is designed to be able to focus on the upper surface.

32 is a support rail that supports the upper part of the fryer 33, and a drive mechanism (for rotating the fryer 33) is provided inside.
(not shown) is attached.

Reference numeral 34 denotes a blow pipe which is disposed at the upper part of the front side of the support rail 32 and communicates with the blow air duct 35, and the air blown out from the blow nozzle 34a (this may be a slit) is directed to the support rail. The liquid flows along the upper surface of 32 toward the roller beam 1 side.

Reference numeral 36 denotes an intake pipe arranged at the upper edge of the rear end of the roller beam 1 and communicating with the intake duct 37, and the intake opening 36
a allows the air passing between the upper surface of the roller beam 1 and the lower edge of the air control plate 30 to be sucked in.

Next, the operation of the cleaning device on the roller part and the flyer support rail in the roving frame constructed as described above will be explained.

Now, when the roving frame is in operation, air blown from a blowpipe (not shown) disposed between the fiber passing sections of the top and bottom rollers 3 to 6, 7 to 10 blows the roller necks, condensers, guides, etc. The fluff that is about to accumulate on the collector etc. is guided to the front of the roller part along with the accompanying airflow due to the rotation of the rollers and the running of the fiber bundle, and the fluff is deposited on the support rail 32, and is removed from the roller part to the flyer top 33a. The fly fluff generated by the rotation and vibration of the roving that leads to this is also deposited on the support rail 32, and these fluff are blown out from the blowpipe 34 and moved by the air flow flowing along the upper surface of the support rail 32 to the roller beam 1. The air is sucked in by the intake pipe 36 through the space between the air intake pipe 36 and the air control plate 30, and is guided to the intake duct 37.

On the other hand, the waste cotton B attached to the Clear Floss 13 is removed by the comb 2.
8, the air is continuously scraped off, moved downward and sucked into the intake pipe 36.

At this time, since there is an air control plate 30 in front of the waste cotton, floating is suppressed, and the upper surface of the roller beam 1 and the air control plate 3
0 and is reliably guided to the intake pipe .

In this embodiment of the present invention, the air control plate 30 is attached to the front surface of the mounting plate 29 of the comb 28 and the mounting bracket 31, so that the air flow sent from the support rail 32 side is directed to the upper surface of the roller beam 1. By rectifying the flow along the comb 28 side and preventing the air from rising toward the comb 28 side, the waste cotton B drawn out from the comb 28 can be reliably guided to the intake pipe 36, and the scattering of fluff to the outside of the machine can be prevented. This prevents the comb drive unit from getting wrapped in waste cotton and absorbing its oil, allowing the comb drive unit to operate smoothly.

In the embodiment described above, the air control plate 30 was installed just in front of the comb 28 so as to interlock with the comb, but it may be fixed so as to be located in front of the comb 28 using the roller stand 2.

In these cases, it is desirable to bring the upper edge of the air control plate 30 as close to the clear luff cloth 13 as possible.

In this way, the present invention provides for the front end of the flyer support rail and the rear end of the roller beam adjacent to the support rail.
A blower pipe and an intake pipe are respectively provided, and in front of the clear luff cleaning comb, air flow that is injected from the blower pipe and flows on the upper surface of the flyer support rail and roller beam with fluff placed thereon is directed to the intake pipe. By disposing the air control plate for guiding, there is an effect that the floating and scattering of waste cotton drawn out from the comb can be prevented, and smooth operation of the comb drive unit etc. can be performed.
