4. PESCRIPTION

Field of Invention

The present invention relates to a waste minimiser and suction less waste collection system for ringframe to be used in Textile Spinning Machineries.

BACKGROUND OF THE INVENTION

In ringframes feed material (roving) will be continuously fed to drafting rollers to get drafted down to desired thickness and the drafted fibers will be twisted and wound on to a package as yarn.

There are many reasons for breakage of yarn in between the nip of the drafting delivery rollers and the package. A suction system is provided to suck the drafted fieece of fibers delivered from the delivery roller following a yarn break still attended by the ringframe worker.

The suction motor will work continuously and through the suction tubes with slots provided at every delivery point the fiber fieece will be sucked to the central filter box if there is yarn break. The roving will continué to feed even if there is a yarn break and go as waste continuously till the ringframe sider attend to it.

SUMMARY OF INVENTION

My invention is to collect the waste without suction arrangement and stop the feeding of roving completely following a yarn break.

DETAILED PESCRIPTION:

Clearer roller (13) placed under the front bottom delivery roller(ll) with support by a specially designed spring loaded bracket(14). Spring loaded bracket(14) holds the clearer roller(13) always in touch with front bottom delivery roller(ll) under a defined load. As the clearer roller(13) is in touch with front bottom delivery roller(ll) under a defined load the clearer roller(13) will revolve at a surface speed equal to the surface speed of the bottom delivery roller(ll). The revolving clearer roller(13) will observe the fiber fieece drafted out from the particular delivery point where there is yarn break. The dimensions of the Spring loaded bracket(14) is designed so that it will not allow the clearer roller(13) to touch the running yarn(15) and also In any chance in absence of the clearer roller(13), the spring loaded bracket(14) will not touch the front bottom delivery roller(ll). The surface finish of the clearer roller(13) is suitably done to attract and wind the ftber fleece immediately, following a yarn break.

Two stopper wedges(4 & 5) are fitted to the wedge bracket(3) as in drawing and the same is moved forward and backward by an electromagnetic traverse system(2). The electromagnetic traverse system(2) is fitted on the drafting arm bar(l).

The electromagnetic coil(2) get energized following a yarn break signal from Individual spindle monitoring system fitted in the ringframé and moves forward the wedges (4 & 5) through the wedge bracket(3) towards the back pair of rollers (7&8) and middie pair of aprons (9&10).

The wedges(4 & 5) are suitably designed, so that when they move forward, the back wedge (4) will get inserted in between back pair of rollers (7&8) and the front wedge (5) will get inserted in between the middie pair of aprons (9&10) simultaneously. As the wedges (4 & 5) get inserted between the Back pair rollers (7&8) and middie pair of aprons (9&10) the drive transmission to the back top roller(7) and top apron(lO) will be cut off and due to the same, feeding of the roving (R) to the front Pair of drafting rollers (11&12) will be stopped. Once the ringframé worker pulí back the wedge bracket(3) the wedges (4&5) will reléase the roving(6) and the roving(6) will get fed to the front pair of rollers (11&12) to continué the spinning of yarn.

Thé stopper wedges(4&5) are suitably designed, so that it will only sepárate the back pair of rollers (7&8) and middie pair of aprons (9&10) from transmitting the drive to stop feeding of roving(6), but still the back pair of rollers(7&8) and middie pair of aprons (9&10) will have grip on the roving(6), so that the roving(R) will not be pulled by the front pair of drafting rollers(ll&12).

Both the stoppers wedges(4&5) are suitably designed so that it will not disturb the roving(6) While stop the feeding and reléase of the roving(6) by ringframé worker.

The roving(R) left out in between the middie pair of apron's(9&10) nipping point and front pair of delivery rollér's(ll&12) nipping point, will only be drafted out as waste and the same is observed and wound by the clearer roller(13).

5. CLAIMS

I claim

1. A waste minimiser and. suction less waste collection system for ringframe which comprises of clearer roller (13) placed under the front bottom delivery roller(ll) with support by a specially designed spring loaded bracket(14) and Spring loaded bracket(14) holds the clearer roller(13) always in touch with front bottom delivery roller(ll) under a defined load.

2. A waste minimiser and suction less waste collection system for ringframe as claimed in claim no.l wherein as the clearer roller(13) is in touch with front bottom delivery roller(ll) under a defined load the clearer roller(13) will revolve at a surface speed equal to the surface speed of the bottom delivery roller(ll)

3. A waste minimiser and suction less waste collection system for ringframe as claimed in claim nos.l and 2 wherein the revolving clearer roller(13) will observe the fiber fleece drafted out from the particular delivery point where there is yarn break

4. A waste minimiser and suction less waste collection system for ringframe as claimed in claim nos.l, 2 and 3 wherein, two stopper wedges(4 & 5) are fitted to the wedge bracket(3) as in drawing and the same is moved forward and backward by an electromagnetic traverse system(2) and the electromagnetic traverse system(2) is fitted on the drafting arm bar(l).

5. A waste minimiser and suction less waste collection system for ringframe as claimed in claim nos.l, 2, 3 and 4 wherein the electromagnetic coil(2) get energized following a yarn break signal from Individual spindle monitoring system fitted in the ringframe and moves forward the wedges (4 & 5) through the wedge bracket(3) towards the back pair of rollers (7&8) and middle pair of aprons (9&10).
