The delivery device 2 and receiving surface 3 are movable relative to each other, for example by rotating to deliver the sliver in a coiled arrangement. The receiving surface may also be movable horizontally C, D to form the sliver pile. The deposited sliver is arranged to be moved by mechanical means, such as a carriage 3 or conveyor belt. The receiving surface may also be able to be displaced vertically and means may be provided for transferring the sliver pile to a further support.

Description

Fibre sliver deposit apparatus for a spinning preparation machine, especially a draw frame or carding machine.

5 The invention relates to an apparatus at a spinning preparation machine, especially a draw frame or carding machine. Arrangements are known in which, at the outlet of the spinning preparation machine, a fibre sliver is delivered 10 by a delivery device and deposited on a base, the delivery device and the base being movable relative to one another, and the fibre sliver (sliver bundle) deposited on the base being arranged to be supplied to a processing machine located downstream.

15 In one known apparatus (EP 0 457 099), the fibre sliver produced by the machine (carding machine, draw frame) delivering the fibre sliver is deposited in a spinning can of rectangular cross-section. In that arrangement, the spinning can is moved back and forth in the depositing 20 area. After the sliver, which is deposited in a ring arrangement, has been filled into the can, the can, together with the fibre sliver, is conveyed out of the depositing area and supplied to a device located downstream. A plurality of filled cans are held in

- 2 - intermediate stores and, from there, are supplied to, example, a spinning machine. Transportation of the cans between the store and the spinning machine is performed on a transportation carriage. A disadvantage of the apparatus 5 is the high outlay in terms of apparatus. In addition, a large number of cans (empty cans) have to be brought into the depositing area of the machines (draw frame, carding machine) delivering the fibre sliver, and the cans filled with fibre bundles (full cans) have to be moved out again 10 from the depositing area. Added to the fact that the machine has to be structurally adapted in order to match the can, and the onerous handling, together with the additional work of conveying and transporting the cans, the outlay on the cans themselves (purchase, storage, repair 15 and the like) is very substantial. Finally, the fibre sliver has to be taken out of the cans again at the processing machine located downstream.

: is an aim of the invention to provide an apparatus of the kind described at the beginning that avoids or 20 mitigates the mentioned disadvantages and, especially, that makes possible, by simple means, displacement of the deposited fibre sliver (fibre bundle) within the depositing area and/or out from the depositing area of the machine and

that allows the outlay in terms of apparatus to be substantially reduced.

The invention provides a fibre deposit apparatus at a spinning preparation machine, comprising a delivery device 5 for delivering fibre sliver and a substantially planar receiving surface for receiving and collecting the fibre sliver, the receiving surface and the delivery device being displaceable relative to one another within a depositing area in which the fibre sliver is to be deposited, and the arrangement comprising means for displacing the collected fibre sliver from the deposit area.

The fact that the deposited fibre sliver (fibre bundle) as such can be displaced by mechanical means both within the depositing area during sliver deposition and out from 15 the depositing area after sliver deposition makes it possible to simplify processing of the fibre sliver very substantially. It is no longer necessary for the fibre slivers to be removed from cans or the like at the processing machine located downstream, for example a 20 spinning machine. Structural adaptation of the machine (draw frame, carding machine) delivering the fibre sliver in order to match a can is not required. In particular, all outlay relating to the purchase, storage, repair and the like of a large number of cans is entirely avoided.

l 4 - The invention also provides an apparatus at a spinning preparation machine, especially a draw frame or carding machine, in which, at the exit, a fibre sliver is delivered by a delivery device and deposited on a base, the delivery 5 device and the base being movable relative to one another, and in which the fibre sliver (sliver bundle) deposited on the base is arranged to be supplied to a processing machine located downstream, wherein the deposited fibre sliver (sliver bundle) is arranged to be moved by mechanical 10 means, which brings about displacement of the fibre sliver (fibre bundle) within the depositing area and/or out from the depositing area without additional containers or the like. The invention thus offers the possibility of a can-

free transport system between a sliver-delivering machine IS and a downstream sliver-receiving machine.

Advantageously, the delivery device is a rotary revolving plate. Advantageously, the fibre sliver is arranged to be deposited in a ring arrangement. The delivery device may be stationary. Advantageously, the 20 base is movable back and forth horizontally.

Advantageously, the sliver bundle is arranged to be moved back and forth horizontally. The base may be arranged in stationary manner. The base may be arranged to be raised and lowered vertically. The base may be a conveyor belt.

- 5 The base may be a transportation device, for example a carriage. The conveyor belt may be arranged on the carriage. The length of the conveyor belt may correspond to the maximum displacement in the longitudinal direction S beneath the revolving plate. The length of the conveyor beet may correspond to at least twice the maximum displacement in the longitudinal direction beneath the revolving plate and extend out from the depositing area.

The mechanical means may be a pushing device, for example a 10 slider or the like. Advantageously, a displacement device for the deposited fibre sliver (sliver bundle) is associated with the depositing area. Advantageously, the displacement device displaces the deposited fibre sliver (sliver bundle) back and forth along the deposition path.

15 Preferably, the displacement device is capable of conveying or transporting the deposited fibre sliver (sliver bundle) away from the depositing area after deposition. The deposited fibre sliver (sliver bundle) may be arranged to be displaced. The deposited fibre sliver (sliver bundle) 20 may be arranged to be displaced within the depositing area.

Preferably, the deposited flbre sliver (sliver bundle) is arranged to be displaced out from the depositing area.

Advantageously, the deposited fibre sliver (sliver bundle) is arranged to be displaced out from the depositing area by

means of the upper portion of the conveyor belt. A lifting and lowering device may be provided for the base. The lifting and lowering device may comprise at least two belt parts. The lifting and lowering device may have a lifting 5 and lowering cylinder, for example a hydraulic or pneumatic cylinder. The lifting and lowering device may comprise a scissors framework. The lifting and lowering device may comprise spring elements. The base may be a lifting platform for example a plate or the like. Advantageously, 10 the lifting platform or the like is, on its upper surface, in a form conducive to sliding. Advantageously, for assisting the deposition process, fixing elements or the like are provided. Advantageously, the deposited fibre sliver (sliver bundle) is conveyed away from the depositing 15 area onto a base. The base may be a transportation tray or the like. A conveyor device arranged outside the depositing area may be associated with the base for the deposited fibre sliver (sliver bundle). A transportation device arranged outside the depositing area, for example a 20 hanging conveyor or the like, is associated with the base for the deposited fibre sliver (sliver bundle).

Preferably, the deposited fibre sliver (sliver bundle) is arranged to be displaced out from the depositing area in jolt-free or almost jolt-free manner. Preferably, the

- 7 change in the velocity of the displacement device in the course of starting-up and braking is carried out in a substantially continuous (stepless) manner. Preferably, the deposited fibre sliver (sliver bundle) is arranged to 5 be displaced out from the depositing area at uniform velocity. Preferably, a controllable drive device, for example a drive motor, is associated with the displacement device. Preferably, the controllable drive device is connected to an electronic control and regulation device.

10 Preferably, the driven displacement device is capable of brining about stable displacement of the deposited fibre sliver (sliver bundle). Preferably, the deposited fibre sliver (sliver bundle) is arranged to be displaced within the depositing area in jolt-free or almost jolt-free 15 manner. The fibre sliver may be freely deposited in the depositing area. Advantageously, the fibre sliver is arranged to be displaced in freely deposited form.

The invention further provides a method of depositing fibre sliver, comprising delivering the fibre sliver onto a 20 substantially planar receiving surface. Advantageously, the deposit of sliver is substantially without any lateral support. Advantageously, the receiving surface is displaced back and forth during deposit of the fibre sliver, the displacement being substantially jolt-free,

whereby the deposited fibre is substantially self-

supporting during the displacement.

Certain illustrative embodiments of the invention will be described hereinafter in greater detail with reference 5 to the accompanying drawings, in which: Fig. la is a diagrammatic side view of a draw frame together with an apparatus according to the invention with a carriage used for sliver deposition in 10 an end position beneath the revolving plate; Fig. lb is a diagrammatic side view of the draw frame and apparatus according to Fig. la, but with the carriage in the other end position beneath the revolving plate; Fig. lc is a diagrammatic side view of the draw frame and apparatus according Figs. la, lb, but with the carriage to 20 the outside of the sliver-depositing device; Fig. 2 is a perspective view of a draw frame with a second embodiment of the invention having a sliver-delivering

- 9 device using a conveyor belt for sliver deposition; Fig. 3 is a diagrammatic side view of a carding machine together with an apparatus 5 according to the invention; Figs. 4a, 4b are a top view (Fig. 4a) and side view (Fig. 4b) of the sliver bundle freely deposited on the surface of the carriage; 10 Fig. 5a is a diagrammatic side view of an embodiment having, for sliver deposition and as conveying-away device, a conveyor belt that can be raised and lowered, during the depositing procedure, wherein 15 the movement back and forth is carried out by means of a carriage; Fig. 5b is a diagrammatic side view of the embodiment of Fig. 5a during the conveying-away procedure; 20 Fig. 6a is a diagrammatic side view of an embodiment having a push device for changing of the sliver bundle; and Fig. 6b is a diagrammatic side view of an embodiment having a lifting device and a

l relatively long conveyor belt which serves, at the same time, for both movement back and forth and for conveying-away. 5 Figs. la to lc show in diagrammatic side view, a high performance draw frame 1 (autoleveller draw frame), for example the HSR 1000 (trade mark) high-performance draw frame made by Trutzschler GmbH & Co. KG of Monchengladbach, Germany. The fibre slivers, coming from cans (not shown), 10 enter a drawing mechanism, are drawn out therein and, after the exit from the drawing mechanism, are combined to form a fibre sliver. The fibre sliver passes through a revolving plate 2 and is then deposited as a sliver bundle 4 in a ring arrangement on a base, for example a carriage 3 having 15 a rectangular upper surface 3a, which moves back and forth in the direction of arrows A and B. The carriage 3 is driven by a controllable drive motor 5, which is connected to an electronic control and regulation device 6, for example a machine control means. Reference numeral 10 20 denotes a cover plate for the sliver-depositing device (coiler), which cover plate is connected to the supporting plate 7. Reference letter F denotes the work direction (flow of fibre material) in the draw frame, the fibre sliver 4 being deposited by the revolving plate 2 in a

substantially perpendicular direction. Reference numeral 8 denotes the depositing area, reference numeral 9 denoting the area to the outside of the depositing area 8. The depositing area 8 encompasses the region a according to 5 Fig. lb. Fig. la shows one end position and Fig. lb shows the other end position of the carriage 3, which moves back and forth horizontally beneath the revolving plate 2 in directions A, B. during deposition of the fibre sliver 4.

10 The sliver bundle 4 is likewise moved back and forth beneath the revolving plate 2 in the direction of arrows A, B. After it has reached the end position shown in Fig. la, the carriage 3 moves in the direction of arrow C, during which the carriage 3 is accelerated, driven at constant 15 velocity and then braked. After it has reached the end position shown in Fig. lb, the carriage 3 moves back in the direction of arrow D, during which the carriage 3 is accelerated, driven at constant velocity and then braked.

Switching-over between the back and forth movements is 20 accomplished by means of the control device 6 in conjunction with the drive motor 5. After deposition of the sliver bundle 4 on the surface 3a has been completed, the carriage 3, together with the sliver bundle 4, moves out from the sliver-depositing device (coiler) in the direction

- 12 of arrow E. The control means 6 switches over the movement of the carriage 3 when the back and forth movement (arrows A, B) during sliver deposition is changed to movement out (arrow E) from the depositing area 8.

5 The variable-speed electric motor 5 drives the carriage 3 at jolt-free or almost jolt-free velocity. In particular, acceleration and braking are carried out in jolt-free or almost jolt-free manner, that is, smoothly.

The velocity between acceleration and braking is constant.

10 By that means it is ensured that the sliver bundle 4 remains stable both during movement back and forth within the depositing area 8 according to Figs. la and lb and during movement out from the depositing area 8 according to Fig. lo. The movements are so controlled that a production 15 rate which is as high as possible is achieved, without the sliver bundle slipping or, even, tipping over.

Fig. 2 shows that, in the case of the draw frame according to Fig. 1, round cans 44 are arranged beneath the sliver intake 45 and the feed slivers 46 are drawn off by 20 way of rollers and supplied to the drawing mechanism. After passing through the drawing mechanism 11, the drawn-out sliver 12 reaches the revolving plate 2 and is deposited in rings on a rectangular plate 13. The plate 13 is arranged on an endless revolving conveyor belt 14, which is driven

- 13 by a controllable electric motor 15, which brings about the movement of the conveyor belt 14, together with the plate 13 and the sliver bundle 4, back and forth in the direction of arrows G. H. The electric motor 15 is 5 connected to an electronic control and regulation device 6.

Fig. 3 shows a carding machine, for example a high-

performance DK903 (trade mark) carding machine made by Trutzschler GmbH & Co. KG, having a feed roller 16, feed table 17, lickers-in 18a, 18b, 18c, cylinder 19, doffer 20, 10 stripper roller 21, nip rollers 22, webcollecting element 24, web funnel 25, draw-off rollers 26, revolving card top 28 and caller 29. Curved arrows indicate the directions of rotation of the rollers. Reference letter I denotes the work direction of the carding machine. Above the coiler 15 cover plate 30 there is a housing 31 in which a rotary revolving plate 2 is located. The base is in the form of a carriage 3, which has, on its upper surface, a rectangular plate 30. The carriage 3 is moved back and forth in the direction of arrows K, L by means of a drive device, for 20 example a controlled motor 32, during deposition of the fibre sliver 4 by the revolving plate 2.

Fig. 4a shows, in a top view, a fibre sliver bundle 4 freely deposited in a ring arrangement on the surface 3a of

the carriage 3. Fig. 4b shows, in a side view, the fibre sliver bundle 4 standing free on top of the carriage In the embodiment of Fig. 5a, there is provided a carriage 3 on the upper surface of which there is arranged 5 a holding apparatus 34a, 34b, for example posts, on which a conveyor belt 33 is so mounted that its height can be adjusted in the direction of arrows M, N. The sliver bundle 4 is deposited on the upper portion 33a of the conveyor belt 33. During sliver deposition, the carriage 3 10 moves back and forth in the direction of arrows C, D. Each time an end position is reached (compare Figs. la, lb), the conveyor belt 33 is adjusted downwards in direction M by about one fibre sliver thickness, for example 10 mm, by means of a drive motor (not shown). Referring to Fig. 5b, 15 when fibre sliver deposition has been completed, the upper portion 33a of the belt is moved in direction R. for example by means of a controlled drive motor (not shown), so that the sliver bundle 4 is slid onto a substantially level support surface 35 located alongside, for example a 20 transportation tray. That edge of the support surface 35 which faces the carriage 3 is, for example, bevelled-off, rounded-off or the like.

In the embodiment of Fig. 6a, there is arranged on the carriage 3 a lifting platform 36, for example a plate,

which can be mounted on holding elements in a manner known per se, for example from DE 44 07 849 Al, and adjusted in the direction of arrows O. P. On the carriage 3 there is provided a supporting element 37, for example a post, on 5 which a pushing device 38 is mounted by way of a suitable controlled drive element 39, for example a pneumatic cylinder, spindle drive or the like. Each time an end position is reached, the platform 36 is adjusted downwards in direction P by about one fibre sliver thickness, for 10 example 10mm. When deposition of the sliver bundle 4 on the surface of the lifting platform 36 has been completed, the pushing device 38 is moved against the sliver bundle 4 in the direction of arrow S so that the sliver bundle 4 is pushed from the lifting platform 36 onto the support 15 surface 35 as a result of direct contact pressure from the pushing device 38. The support surface 35 rests on a stand 40 or the like, can be taken off the surface of the stand 40 together with the sliver bundle 4 and can be supplied to a processing device located downstream, for 20 example a spinning machine, or a store.

In the embodiment of Fig. 6b, there is provided a lifting plate 41, which can be raised and lowered by means of lifting elements 42a, 42b, for example controlled pneumatic cylinders, in the direction of arrows T. U. and

V, W. On the surface of the lifting plate 41 there is provided a conveyor belt 43, the belt portions of which can be moved in the direction of arrows X, Y. The drive and control means for the conveyor belt 43 correspond to the 5 kind shown in Fig. 2. During deposition, the upper portion 43a of the belt is moved back and forth in the direction of arrows X, Y beneath the revolving plate 2.

After the fibre sliver has been deposited in the form of a sliver bundle 4 on the upper portion 43a of the belt, the 10 drive motor 15 (see Fig. 2) is so controlled by the control means 6 (see Fig. 2) that the upper portion 43a of the belt moves the sliver bundle 4 out from the depositing area 8 beneath the revolving plate 4 and unloads it onto a support surface 35.

15 In contrast to the known apparatus in which the sliver is deposited in a can having an upstanding and circumferentially continuous wall enclosing the base, the receiving surface of the invention is open in that it is substantially unenclosed by any such can wall. Therefore, 20 the arrangement is such that the deposited fibre is without or substantially without lateral support and is thus free-

standing or substantially free-standing during movement of the receiving surface. It will be appreciated that the apparatus will then be arranged to effect a movement which,

during braking and acceleration, is smooth, that is continuous and substantially jolt-free. The invention in particular includes fibre deposit apparatus having a delivery device and a substantially planar, 5 circumferentially substantially unenclosed, receiving surface for receiving and collecting fibre sliver delivered by the delivery device, the receiving device and the delivery device being displaceable relative to one another within a depositing area in which the fibre sliver is to be 10 deposited, and the arrangement comprising means for displacing the collected fibre sliver from the depositing area. Except where it is clear that the contrary is intended, the term "fibre sliver" as used herein is to be understood 15 to include any continuous band of loose fibres and, for example, as including fibre structures of the kind produced by a carding machine and fibre structures of the kind typically produced by a draw frame.
