Filed Nov. 9, 1966, Ser. No. 593,054 4 Claims. (Cl. 19-107) ABSTRACT OF THE DISCLOSURE A card in which waste and flat strips are fed to respective intake members constituted by pairs of rollers rotating in opposite directions which feed the strips and Waste to respective adjacent ducts connected to a shutoli mechanism which periodically opens the ducts simultaneously for the separate elimination of the flat strips and Waste without their intermixing.

The present invention relates to apparatus for carding and cleaning cotton fibers, and more particularly concerns cotton cards finding application in the textile industry.

Known in the prior art is a card in which flat strips and wastes are pneumatically eliminated from the intake members of the flat stripper and conveyor along separate air ducts (see Patent 84,310, class 76b10 and complementary Patent 124,850, class 76bl0 issued in the U.S.S.R.).

The drawbacks presented by the aforementioned card are high air consumption for the continuous elimination of card strips and waste from the machine into a common pneumatic system.

Moreover, a damper closing the air duct of the pneumatic system does not ensure either a good sealing of the air ducts or the simultaneous elimination of waste and flat strippings from one automatic control station.

This card also presents the drawback of having a flat stripper with intake members which do not ensure periodic pneumatic elimination of card strips.

An object of the present invention is to provide a card in which simultaneous automatic elimination of flat strips and waste is carried out according to a preset program with a minimum air consumption.

Another object of the present invention is to provide intake members arranged close to the flat stripper and card conveyor which promote periodic pneumatic elimination of flat strips.

With this and other objects in view, the card is constructed so that the elimination of fiat strips and waste from the intake members of the flat stripper and conveyor is effected pneumatically along separate air ducts. According to the invention, a shut-off arrangement is provided through which separate air ducts are led, ensuring periodic and simultaneous elimination of flat strips and waste without their being mixed together; the intake members are in the corm of a pair of rollers rotating in opposite directions and disposed adjacent to air ducts provided at this point with a slot of the same length as the rollers.

It is expedient to use a shut-01f arrangement in the form of an electromagnetic valve with a spring-loaded disk having two through holes, said disk being connected with the electromagnet armature and enclosed in a sealed housing with through holes for attaching the ends of air ducts.

ice

In this way in the proposed card, a periodic and simultaneous elimination of waste and fiat strips from intake members is ensured according to a preset program with their transfer into air ducts of the pneumatic system. This allows a reduction in air and current consu-mption.

A better understanding of the objects and advantages of the present invention will be obtained from the following description of an embodiment of the proposed card and the accompanying drawings, in which:

FIG. 1 is an elevation view of a card provided with an arrangement for periodic pneumatic elimination of waste and flat strips according to the invention;

FIG. 2 is a perspective view of the shut-off arrangement and intake members in the air ducts, according to the invention; and

FIG. 3 is a perspective view of the shut-01f arrangement, according to the invention.

In FIG. 1 there is shown a card comprising a feeding unit 1, a receiving or taker-in unit 2, a main cylinder 3, belts 4, a doffer 5, a dofier comb 6, delivery rollers 7 and a coiler 8 for coiling the sliver in the container 9. Additionally there are provided intake members 10 and 11, the latter being constituted as two pairs of rollers rotating in opposite directions.

One pair of rollers 12 is provided at the Waste elimination conveyor 13, while the second pair of rollers 14 is arranged at the fiat stripper.

The rollers in

pairs

12 and 14 are driven in opposite rotation by the drive (not shown in the drawing) of the card, through sprockets 16 (FIG. 2), chain transmission 17, and gear 18.

The rollers 12 are located adjacent the air ducts 19 and the rollers 14 adjacent air ducts 20. At the point of their contact with the

rollers

12 and 14, the

air ducts

19 and 20 are provided with

slots

21 and 22 of the same length as the rollers.

The

air ducts

19 and 20 are connected to a central pneumatic system by means of

intermediate air ducts

23, 24, 25 and 26.

For periodic elimination of waste and flat strips along the

air ducts

19, 20, 23, 24, 2S and 26, the latter are equipped with a shut-01f device in the shape of an electromagnetic valve 27.

The electromagnetic valve 27 is made as a rotatable disk 28 (FIG. 3) fixed on a shaft 29 connected with a lever 30. The disk 28 is enclosed between the

walls

31 and 32 which when secured together form a hermetically sealed housing. Two coaxial holes are provided in the

walls

31 and 32 and two holes in the disk 28, the latter being arranged between the walls, so that its holes in non-Working position do not coincide with the holes in

Walls

31 and 32.

The ends of the

intermediate air ducts

23 and 25 fit into the holes of wall 31 and the

air ducts

24 and 26 fit into the holes of the wall 32.

For turning the disk 28, the lever 30 is connected with the armature of an electromagnet 33 (FIG. 2) by means of rod 34.

For returning the disk 28 (FIG. 3) into initial position the lever 30 is connected with a spring 35.

The shut-off arrangement ensures the simultaneous periodic opening and closing of

air ducts

19, 20, 23, 24, 25, 26 and the connection of the intake devices 10 and 11 with the pneumatic system serving for the periodic .automxatic elimination of waste and flat strips from the intake devices 10 and 11 of the card according to a preset program.

1 The card with the automatic arrangement for periodic pneumatic elimination of waste and flat strips according to a preset program operates in the following way:

The flat strips removed by the mechanism 15 from the belts 4 are forwarded, in any convenient manner known in the art, to the intake device 10 with the rollers 14 rotating in opposite directions.

The pair of rollers 14 grasps the flat strips and uniformly feeds them throughout the full width of the rollers through the slot 22 into the air duct 20. At the same time, the second pair of rollers 12 of the intake device 11 grasps the waste removed by the conveyor 13 from under the card and feeds the waste through slot 21 into the air duct 19.

The external programming automatic station (not shown in the drawing) at preset time intervals energizes the electromagnet 33 (FIG. 2) which turns the disk 28 by means of lever 30 and rod 34 in order to bring in coincidence the through holes of the disk with the holes in

walls

31 and 32.

In the air ducts of the central pneumatic system, a vacuum is created, and as a result fiat strips are eliminated via the

air ducts

19, 23 and 24 and the waste via the

air ducts

20, 25 and 26. According to a preset program the automatic station after a certain delay deenergizes the electromagnet 33, and the rotatable disk 28 is returned by the spring 35 into initial position thus closing the holes in the air ducts.

The disk 28 enclosed in a hermetically sealed housing excludes any possibility of undesirable air suction into the pneumatic system which allows periodic simultaneous elimination of waste and flat strips with minimum air consumption, while the intake devices 10 and 11 ensure flat strips and waste accumulation for subsequent periodic elimination from the card.

What is claimed is:

1. In a card, a device for the elimination of flat strips and waste comprising first and second intake members adapted for respectively receiving flat strips and waste, said members each including a pair of rollers rotating in opposite directions and air ducts for the pneumatic elimination of the fiat strips and waste delivered to the intake members, said air ducts being positioned adjacent said rollers and having respective slots of the same length as the rollers and extending coextensive therewith, and shutofif means coupled to said ducts for periodically and simultaneously opening the ducts for the separate elimination of flat strips and waste without their intermixing.
