Description

-1- 2431l70 pparatus on a spinning room machine, especially a spinning

preparation machine, for depositing fibre sliver The invention relates to an apparatus on a spinning room machine, especially a spinning preparation machine, for example a flat card, draw frame, combing machine, integrated drafting system, roller card or the like, for depositing fibre sliver. In a device known from DE 102 05 061 A there is a delivery device (coiler plate) for depositing fibre sliver and a substantially planar receiving support surface for receiving and collecting the fibre sliver in the form of a can-less fibre sliver package, the receiving support surface being substantially unenclosed, the receiving support surface and the delivery device being displaceable relative to one another in a depositing area in which the fibre sliver is depositable, the receiving support surface being movable back and forth horizontally, the delivery device being in a fixed position during deposition of the fibre sliver, and in which the receiving support surface is lowerable vertically during deposition of the fibre sliver.

It is an aim of the invention to improve such an apparatus to the effect that the production of the fibre sliver package can be considerably improved.

The invention provides an apparatus on a spinning room machine for depositing fibre sliver, comprising: a delivery device for delivering fibre sliver; a receiving support having a support receiving surface for receiving and collecting the fibre sliver that is deposited thereon by the delivery device, the receiving support surface being substantially unenclosed and being lowerable during deposition; and a displacement device for effecting relative horizontal displacement of the delivery device and the receiving support surface; wherein the delivery device and the receiving support are in contact with the fibre sliver deposited in the form of a fibre sliver package, whereby the fibre sliver package is deposited as a sliver package, whereby the fibre sliver package is positioned stably during the relative movement of the delivery device and the receiving support surface.

Because the delivery device and the receiving support surface are in contact with the deposited fibre sliver, vertical force is exerted on the can-less sliver package as early as in the draw frame, so that the sliver package is pre-compressed. Furthermore, the sliver package is stable to tipping over during the horizontal back and forth displacement. That stability is important, because the displacement of the sliver package can be effected without cans, containers or the like, that is to say there is no support means for the side and end faces.

Advantageously, the horizontal stroke of the receiving support surface is adjustable. Advantageously, the length of the sliver package is adjustable by means of the horizontal stroke. Advantageously, the horizontal stroke is predeterminable by the drive control means of the receiving support surface for predetermining the length of the sliver package.

Preferably, the receiving support surface is raisable and lowerable vertically. Advantageously, the length of the receiving support surface corresponds to the maximum stroke in the longitudinal direction beneath the rotary plate. Advantageously, the receiving support surface is associated with a pressure device, for example a pusher or the like. Advantageously, the receiving support surface displaces the deposited fibre sliver (sliver bundle) back and forth along the deposition path. Advantageously, the receiving support surface is capable of conveying the deposited fibre sliver (sliver bundle) out of the depositing area after deposition. Advantageously, the deposited fibre sliver (sliver package or package group) is displaceable, especially is displaceable out of the depositing area. Advantageously, there is a raising and lowering device for the receiving support surface.

Advantageously, the receiving support surface is a lifting base, for example a board or the like. Preferably, the lifting base or the like is constructed so as to have good sliding properties on the upper side. Advantageously, for supporting the deposition process, fixing elements or the like are provided on the surface of the receiving support surface. Advantageously, the deposited fibre sliver (sliver package or package group) is displaceable jolt- free or almost jolt-free in the depositing area.

Advantageously, the alteration in the speed of the displacement device at turning points on deceleration and acceleration takes place substantially continuously (steplessly). Advantageously, the displacement device is associated with a controllable drive device, for example a drive motor. Advantageously, the controllable drive device is connected to an electronic control and regulation device. Advantageously, the driven displacement device is able to effect stable displacement of the deposited fibre sliver (sliver package or packages).

Fig. la, lb shows a draw frame 1, for example a draw frame of the kind known as the TD 03 (Trade Mark) made by TrUtzschjer GmbH & Co. KG of Mänchengladbach, Germany. A plurality of fibre slivers, coming from an upstream lattice (feed table), enter a drafting system 2, are - 11 drafted therein and, after the outlet of the drafting system 2, combined to form a fibre sliver 12. The fibre sliver 12 passes through a rotary plate 3 and is then deposited in rings on a base which moves back and forth in the direction of arrows A and B, for example a support plate 4 having a rectangular top face 4, to form a can- less fibre sliver package 5. The support plate 4 is driven by a controllable drive motor 6 which is connected to an electronic control and regulation device 7, for example a machine controller (see Fig. 4). Reference numeral 8 denotes a cover sheet of the sliver delivery device which is adjoined by the rotary plate panel 9. The rotary plate panel 9 is in a fixed position. The rotary plate 3 is rotatably mounted within the panel 9. K denotes the working direction (flow of fibre material) inside the draw frame 1, while the fibre sliver is delivered by the rotary plate 3 substantially in the vertical direction. Reference numeral 10 denotes the depositing area, reference numeral 11 denotes the region outside the depositing area 10. The depositing area 10 for the fibre sliver 12 comprises the path g in accordance with Fig. lb. The support plate 4 is moved horizontally back and forth beneath the rotary plate 3 while the fibre sliver 12 is being deposited. Fig. la shows one end position and Fig. lb shows the other end position of the support plate 4 which moves back and forth horizontally in direction A, B beneath the rotary plate 3 during deposition of the fibre sliver 12. The fibre sliver package 5 is moved back and forth corresponding to A, B - in the direction of arrows C, D beneath the rotary plate 3. Once the end position shown in Fig. la has been reached, the support plate 4 travels in the direction of arrow A, the support plate 4 being accelerated, driven at a constant speed and then braked. Once the end position shown in Fig. lb has been reached, the support plate 4 - 12 travels back in the direction of arrow B, the support plate 4 being accelerated, driven at a constant speed and then braked. Switching-over between the back and forth movements is effected by the control device 7 in conjunction with the drive motor 6 (see Fig. 4).

The variable-speed electric motor 6 drives the support plate 4 at a joltfree or almost jolt-free speed.

In particular, the acceleration and the braking are jolt- free or almost jolt-free. The speed between acceleration and braking is constant. By that means, the fibre sliver package 5 remains stable both during the back and forth movement in the depositing area 10 according to Fig. la and lb and during the movement out of the depositing area according to Fig. 2. The movements are so controlled that the production rate achieved is as high as possible, without the fibre sliver package 5 (sliver bundle) slipping or even tipping over.

While the fibre sliver 12 is being deposited, the control device 7 (see Fig. 4) controls the back and forth movement of the support plate 4 in order to produce a stable can-less fibre sliver package 5. In accordance with one embodiment, the rotary plate 3 rotates in a fixed position and deposits the fibre sliver 12 on the support plate 4 at a substantially constant deposition force The constant deposition force is achieved inter alia by deposition of a constant amount of fibre sliver 12 per fibre material layer of the fibre sliver 12. If, for example, the rotary plate 3 deposits fibre sliver 12 on the support plate 4 or on top of already deposited fibre sliver rings, each layer of fibre sliver rings receives a substantially constant amount of fibre sliver 12 either during the forward movement or during the backward movement. Because the amount of fibre sliver 12 per layer is constant, stability of the fibre sliver package 5 is - 13 - achieved.

The amount by which the support plate 4 moves back and forth is also controlled by the increasing stability of the fibre sliver package 5. Whenever the support plate 4 reaches the turn-round point of either the forward or backward movement, the control means 7 brakes the support plate 4, the support plate 4 reaching a border region 402a or 402b of the fibre sliver package 5, and accelerates the support plate 4 when the support plate 4 leaves the border region 402a or 402b. Between the border regions 402a and 402b on each side of the fibre sliver package 5, the control means 7 controls the support plate 4 at a constant speed. The border region 402a or 402b is the location at each end of the fibre sliver package 5 where the fibre sliver rings deposited on the support plate 4 do not completely overlap one another (see Fig. 3a, 3b).

The border region 402a or 402b is located shortly before the turn-round point of the movement of the support plate 4 at each end of the fibre sliver package 5. In contrast, in the non-border region 404, either during the forward or return movement of the support plate 4, the rearward edge of each fibre sliver ring is also arranged from above on the forward edge of the previously deposited fibre band ring.

With regard to the small amount of fibre sliver that is deposited in the border region 402a or 402b, the control device 7 brakes the support plate 4 so that more fibre sliver 12 can be deposited in the border region 402a or 402b and accelerates the support plate 4 to a constant speed in the non-border region 404. The braking of the support plate 4 results in an increase in the amount of fibre sliver deposited in the border region 402a or 402b, because the rotary plate 3 deposits the fibre sliver 12 at a constant rate irrespective of the movement of the w - 14 - support plate 4. Whenever the support plate 4 is braked, more fibre sliver 12 can be deposited at that point, which corresponds to the non- overlapping fibre sliver rings close to the turn-round points. The non- uniform speed of the support plate 4 allows a substantially uniform amount of fibre sliver 12 which is deposited in both border regions 402a and 402b and in the non-border region 404 of the fibre sliver package 5 for each layer of fibre sliver 12 during the back and forth movement of the support plate 4. The non-uniform speed of the support plate 4 results in a substantially uniform density of fibre sliver 12 at all points of the fibre sliver package 5. The uniform density of the fibre sliver 12 enables the fibre sliver package 5 to be formed stably on the support surface 5 and allows the fibre sliver package 5 to be accelerated and braked forwards and backwards, avoiding the possibility of the can-less laterally unsupported fibre sliver package 5 becoming unstable or at risk of tipping over.

After the deposition of the fibre sliver package 5 on the surface 4 is complete, according to Fig. 2 the support plate 4, together with the fibre sliver package 5, moves Out of the sliver delivery device in the direction of arrow I. The control means 7 controls the movement of the support plate 4 so that a switch-over is made from the back and forth movement (arrows A, B) for the sliver deposition to the outward movement (arrow I) out of the depositing area 10 into the discharge region 11.

Fig. 3a shows a plan view of a ring-shaped fibre sliver package 5 which has been deposited freely on the top face 4 of the support plate 4. Fig. 3b shows a side view of the fibre sliver package 5 which is arranged freely on the support plate 4. Fig. 3c shows a front view of the fibre sliver package 5, which has been positioned freely on the support plate 4. As shown in Fig. 3a to 3c, - 15 - the fibre sliver package 5 is formed from fibre sliver rings stacked in a substantially rectangular shape. The rectangular shape of the fibre sliver package 5 is created by the way in which the fibre sliver 12 has been deposited. The rotation of the rotary plate 3 by which the fibre sliver 12 is delivered forms a layer of overlapping rings of fibre sliver 12 on a receiving surface 4a of the support plate 4, and the back and forth movement of the support plate 4 under the control of the control device 7 establishes the locations at which the fibre sliver rings are formed on the receiving surface 4. The movement of the support plate 4 has the effect that the deposited fibre sliver rings are arranged on the receiving surface 4i of the support plate 4 staggered relative to one another and partly overlapping one another, which creates the substantially rectangular shape of the fibre sliver package 5 - seen in plan view. At each end of the fibre sliver package 5 caused by the change in the direction of the back and forth movement of the support plate 4 - the fibre sliver package 5 has rounded ends to the rectangular shape, as Fig. 3a clearly shows. The rectangular shape of the fibre sliver package 5 is advantageous, because - as compared with conically or cylindrically shaped fibre sliver packages - it promotes the stability of the fibre sliver package 5.

Fig. 3a shows a plan view of the fibre sliver 12 of the fibre sliver package 5 deposited in a ring arrangement. Fig. 3b and 3c show in side view and in front view, respectively, the fibre sliver package 5 standing freely, that is to say without a can, container or the like, on the upper face 4i of the support plate 4. In respect of the dimensions of the fibre sliver package 5, the length according to Fig. 3a is denoted by reference letter a, the width according to Fig. 3c by reference letter b arid the height according to Fig. 3c by reference letter c. With regard to the dimensions of the support plate 4, the length according to Fig. 3a is denoted by reference letter d, the width according to Fig. 3a by reference letter e and the height according to Fig. 3c by reference letter f. Reference numeral 5 (Fig. 3a) denotes the upper face, reference numeral 5 (Fig. 3b) a long side face and reference letter 53 (Fig. 3c) a short end face of the substantially cuboidal fibre sliver package 5 which is of substantially rectangular cross-section. The other long side face 52, the other short end face 54 and the base surface 56 are not shown.

According to Fig. 4, there is an electronic control and regulation device 7, for example a machine controller, to which a controllable drive motor 6 for the horizontal displacement of the support plate 4, a controllable drive motor 13 for the vertical displacement of the support plate 4 and a controllable drive motor 14 for the rotary plate 2 are connected. A raising and lowering device is mounted on a carriage 20, which raising and lowering device consists of a framework, guide rollers and a flexible transport element, which can be moved in the direction of arrows L and M. The vertically displaceable (see arrows E, F in Fig. la) support plate 4 is provided with two driver elements 15a, 15b. Those driver elements iSa, 15b, which are arranged on the opposite narrow sides of the support plate 4, rest on support elements 16a, 16b, which are attached to perpendicularly arranged flexible transport elements, for example toothed belts 17a, 17b circulating around toothed belt wheels. One of the guide rollers 18a is driven by a motor 13. The motor 13 is in the form of a reversible motor, which can run at different speeds and in both directions of rotation. On arrival of an empty support plate 4, the driver elements l5a, 15b lie - 17 - on the support elements 16a, 16b located at the bottom, so that upward movement of the support elements 16a, 16b brings about an upward movement of the driver elements 15a, 15b and accordingly of the support plate 4. The transport elements 16a, 16b are attached, by means of holding elements 19a, 19b of the framework, to the carriage 20, which is moved horizontally back and forth in the direction of arrows 0, p by a circulating transport element 21, for example a toothed belt circulating around toothed belt wheels.

The rotary plate 3 held by the fixed rotary plate panel 9 deposits fibre sliver 12 on the support plate 4, the resulting fibre sliver package 5standing on the support plate 4 and being moved back and forth in the direction of arrows A, B (see Fig. la). During the ongoing fibre sliver deposition, the upper fibre sliver rings of the fibre sliver package 5 are preferably constantly or substantially constantly in contact with the underside 9a of the rotary plate panel 9. The deposited fibre sliver 12 of the fibre sliver package 5 presses against the underside 9a and against the lower cover face 3a of the rotary plate 3. In order that a pre-determined constant pressing force is exerted vertically on the deposited fibre sliver 12, the open-loop and closed-loop control device 7 regulates the speed of the motor 13 so that the force exerted by the uppermost layer of the fibre sliver 12 remains constant. In other words, the speed of the motor 13 is such that the rate (amount) of downward movement of the support elements 16a, 16b, which are attached to the flexible transport elements 17a, 17b, in conjunction with the speed of fibre sliver deposition by the rotary plate 3 driven by the motor 14 ensures uniform compression of the fibre sliver 12 in each height position of the downwardly moving support plate 4. After each - 18 - stroke g (see Fig. ib) in the horizontal direction, the support plate 4 is displaced downwards by a pre-set amount. That pre-set amount can correspond to the thickness of a single layer of the fibre sliver. The can- less fibre sliver package 5 is pressed against the lower faces 9a and 3a of the rotary plate panel 9 and the rotary plate 3 during the horizontal back and forth movement as a consequence of the resilience inherent in the fibre sliver 12 and as a consequence of the pressing force of the displaceable support plate 4. The fibre sliver package 5 is accordingly stabilised both positively and non- positively during the horizontal back and forth movement.

Fig. 4 shows the carriage 20 with the holding device 19a, 19b, for example framework 19. The holding elements 19a, 19b hold two conveyor belts 17a, 17b, which are able to move the support plate 4 upwards or downwards in the direction of arrows L, M. The can-less fibre sliver package 5 is arranged on the top face 4 of the support plate 4. During fibre sliver deposition, the support plate 4 is moved back and forth in the direction of arrows A, B. Once each corresponding end position (see Fig. la, ib) has been reached, the support plate 4 is displaced downwards in direction E in principle by less than the thickness of a fibre sliver, for example 10 mm, with the aid of the drive motor 13, in order to create a substantially constant space (or room) for the next layer of fibre sliver material to be deposited. The substantially constant room relates to the region between the upper side of the laterally unsupported fibre sliver package 5 and the base surface 3a of the rotary plate 3 and produces a constant filling force per deposited fibre sliver layer.

The substantially constant space allows only substantially constant room for fibre sliver 12 deposited for each fibre sliver layer. A fibre sliver layer represents the amount - 19 - of fibre sliver 12 that is deposited between an individual pair of movement turn-round points for the support plate 4 (that is to say from the point at which the movement of the support plate 4 changes direction as far as the next turn-round point). Deposition of the fibre sliver in the substantially constant space allows a substantially constant density of fibre sliver 12 at all locations within the fibre sliver package 5, which promotes the stability of the fibre sliver package 5.

The substantially constant space formed by lowering (arrow E in Fig. 1) the support plate 4 is filled directly and immediately by the fibre sliver 12 constantly flowing in from the rotary plate 3. During sliver deposition, the upper side of the fibre sliver package 5 presses, with no spacing, against the base surface 3a of the rotary plate 3 and against the base surface 9a of the rotary plate panels 9. There is constant contact. The deposited fibre sliver mass of the fibre sliver package 5 is pressed against the lower faces 3a and 9c as a consequence of the resilience inherent in the fibre sliver 12 and as a consequence of the biasing force of the displaceable support plate 4. At the same time, this results in pre-compactjon of the fibre sliver package 5, which is advantageous for further discharge and further transport of the fibre sliver package 5. As will be apparent from the above, the holding elements l9a and 19b of framework 19 are outside the footprint of the support plate 4. They do not serve to enclose, or laterally support, the sliver package arid do not form a part of the receiving support surface.

Fig. 5 shows a fibre sliver package 5a on a support plate 4 during sliver deposition in the depositing area 10. Reference numeral 20 denotes the carriage (guide device, holding device) which is movable back and forth horizontally. The fibre sliver package 5a is displaced - 20 - horizontally in direction C, D of its longitudinal axis, that is to say in the direction of its long side faces.

Parallel to and spaced apart from a side face 5 there is a fixed side wall 22a which is independent of the carriage 20 and prevents any falling fibre material or the like from entering the machine. The length of the path g (see Fig. ib) (stroke length) is variable by means of the motor 6 (see Fig. 4), so that the length a (see Fig. 3b) of the fibre sliver package 5a is adjustable. Downstream of the depositing area 10 there is arranged the discharge region 11 in which a transport pallet 25 is located on which the two fibre sliver packages 5b, 5c are stored one next to the other.

According to Fig. 6a, 6b, through-holes 4.1.1. are arranged in the top face 4a of the support plate 4.1, through which, according to Fig. 6a, there project the tips 23.1. of conical lugs which are mounted on the top face of a plate 23 arranged on the side 4b remote from the top face 4. The plate 23 can be raised and lowered in the direction of arrows Q, Q2, so that when the plate 23 is lowered in direction Q2 the tips 23.1 become disengaged from the holes 4.1.1 according to Fig. 6b. According to Fig. 6a, the tips 23.1 project through the holes 4.1.1 for only a short time at the start of fibre sliver deposition, so that the first layer of fibre sliver deposited is held on the regularly smooth top face 4 and does not slide off the top face 4. As soon as the layer of fibre sliver is lying stably on the top face 4, the tips 23.1 are lowered out of engagement in direction Q2, so that at a later stage during discharge the fibre sliver package 5 can slide down from the top face 4 without problems.

According to Fig. 7a to 7c, in the top face 4a of the support plate 4.2 there are arranged longitudinal grooves 4.2.1 into which according to Fig. 7b elongate lifting - 21 - rods 24a, 24b or the like are insertable in direction R1, R2 underneath the lower side 56 of the fibre sliver package 5. In accordance with Fig. 7c, the lifting rods 24a, 24b can be raised in direction S1, S2, with the result that the lower side 56 of the fibre sliver package is lifted away from top face 4 of the support plate 4, so that the support plate 4 can be displaced in direction W underneath the fibre sliver package 5 and without frictional contact with the fibre sliver package 5 (see Fig. lOd) According to Fig. 8, the support plate 4, together with a fibre sliver package 5d, is located in the discharge region 11 above the top face 25 of the transport pallet 25. Transverse to the longitudinal axis of the fibre sliver packages Sb, 5c, that is to say in the direction of their short side or end faces 53, 54, the transport pallet 25 is inclined at an angle a of, for example, 70 to the horizontal, On the side face 252 of the transport pallet 25 close to the base, according to Fig. 8a there is mounted a supporting wall 26, for example a smooth sheet metal wall or the like, which forms an angle of 90 with the top face 25 of the transport pallet 25.

As a result, the fibre sliver package 5c leans against the support wall 26. The fibre sliver package 5b leans against the inclined fibre sliver package 5c in contact therewith.

By virtue of their inclination, the fibre sliver packages 5b, 5c are supported stably on the transport pallet 25 and are secured against tipping over and the like. As also shown in Fig. 8a, the smooth side wall 22b is displaceable in the direction of arrows T1. T2, so that during the discharge of the fibre sliver package 5d troublesome frictional contact with the stored fibre sliver package 5b is avoided. According to Fig. 8b, there is a supporting d - 22 - element 98, for example a perpendicular supporting wall, which can be inclined by about 5 to 100 in the horizontal direction about a pivot bearing 99, in order to incline the discharge fibre sliver package 5a against the stored and inclined fibre sliver package 5b. One or more of the supporting walls 22b, 98 can be adapted to couple and decouple with the receiving support surface.

According to Fig. 9, the storage means is in the form of a belt storage means, in which there is a conveyor belt 29 endlessly circulating around two guide rollers 28a, 28b driven by a motor 27. On the upper belt portion 29 there are arranged, one after the other in direction U1 and lying horizontally on the belt, an empty transport pallet 25a, a transport pallet 5b loaded with a fibre sliver package 5c and a transport pallet 25c loaded with four fibre sliver packages 5b, 5c, Sd, 5e. On one end face 252 of each transport pallet 25a, 25b, 25c there is mounted a supporting wall 26a, 26b, 26c or the like, which is arranged inclined at an angle 1 of about from 50 to 10 relative to the vertical. By virtue of the inclination of the supporting wall 262, the fibre sliver packages 5b, 5c, Sd, 5e are positioned stably on the transport pallets 25b and 25c. Each time a fibre sliver package 5 has been unloaded onto the transport pallet 25b, the upper belt portion 29 moves on in direction U1 by the width b (see Fig. 3c) of a fibre sliver package 5. During or after the loading of the transport pallet 25b, the already full transport pallet 25c can be transported away. Once the transport pallet 25b has been loaded with four fibre sliver packages 5, the upper belt portion 29 is moved in direction U1 so that the full transport pallet 25b moves into the position for being transported away and the empty transport pallet 25a moves into the (middle) position for - 23 - discharge of the fibre sliver packages 5. A fresh empty transport pallet 25a' is then placed on the upper belt portion 29.

In accordance with Fig. lOa, driven by the motor 6, in the course of being discharged from the sliver- depositing area 10 a support plate 4, together with a can- less fibre sliver package Sd, is moved horizontally in direction I and arrives at a position spaced apart by distance h above the top face 25 of the transport pallet 25 (see Fig. 10') and in parallel next to a fibre sliver package 5c already stored on the top face 25 (Fig. lOb).

A holding-back element 27 is then displaced horizontally in direction V1 from a position outside the transport pallet 25 (Fig. lOb) to a position in front of the end face 54 of the fibre sliver package 5d (by a drive device not shown) and spaced apart by distance i above the top face 4 of the support plate 4 (see Fig. 10') (Fig. lOc).

Then - driven by the motor 6 - the support plate 4 alone, without the fibre sliver package 5d, is moved back horizontally in direction J beneath the holding-back element 27 (see Fig. lOd). In the course of that movement in direction J, the fibre sliver package 5d - held in place by the holding-back element 27 - slides of f the smooth surface 4 of the support plate 4, so that the fibre sliver package 5d is removed from the support plate 4. At the same time - as shown in Fig. lOd - the fibre sliver package 5d is deposited on the surface 25 of the transport pallet 25. The distance Ii between the lower face 42 of the support plate 4 and the upper side 25 of the transport pallet 25 (see Fig. 10') is small, so that when sliding off the support plate 4 the fibre sliver package 5d falls onto the transport pallet 25 without problems.

Finally, the holding-back element 27 is moved back horizontally in direction V2 (Fig. lOe).

- 24 - In the position according to Fig. ].Oc, the support plate 4 can be rotated (not shown) about its longitudinal axis through an angle of about from 50 to 100, so that the fibre sliver package 5d is inclined in the direction towards and parallel to the side face 52 of the deposited, inclined fibre sliver package 5b. The rotation of the support plate 4 assists the downward sliding movement of the fibre sliver package 5d from the top face 4.

Alternatively (or additionally) a sheet metal wall or the like can be moved horizontally into the region above the transport pallet 25, which wall can be inclined about a longitudinal axis, so that the fibre sliver package Sd is inclined in the direction towards and parallel to the side face 52 of the fibre sliver package 5.

According to Fig. 11, four can-less fibre sliver packages 5a to 5d are arranged one next to the other on the top face 25. of a transport pallet 25. The sliver end or the end of the last ring of fibre sliver of a top layer (top face 5) is joined to the sliver end or the end of the first ring of fibre sliver of a base layer (base surface 56) of adjacent fibre sliver packages. In the example shown in Fig. 11, the sliver end of the last ring of fibre sliver of the top layer (top face 55) of fibre sliver package 5a is joined to the sliver end of the first ring of fibre sliver of the base layer (base surface 56) of fibre sliver package 5b. The same applies to the sliver ends and the joining together thereof in respect of the further fibre sliver packages 5c and 5d. In that way, by joining together the sliver ends, a single total fibre sliver package consisting of a plurality of individual fibre sliver packages 5a to 5d is created. In the case of supply to and working-off on sliver-fed machines (Fig. 15 to 17 and 19 to 21), it is possible - beginning with the top layer (top face 56) of the fibre sliver package 5d - - 25 - f or all fibre sliver packages of the total fibre sliver package to be worked-off one after the other in a single operation and without interruptions.

In accordance with Fig. 12, there is a fork-lift truck 31 for transporting the transport pallet 25 with fibre sliver packages 5a to 5d arranged on the top face 25. Transverse to the direction of the longitudinal axis of the fibre sliver packages 5a to 5d - that is to say parallel to the short end faces 53 and 54 of the fibre sliver packages 5a to 5d - the transport pallet 25 is inclined at an angle 7 to the horizontal. The correspondingly inclined forks 32 of the fork-lift truck 31 engage under the transport pallet 25 transverse to the longitudinal axes of the fibre sliver packages 5a to 5d.

The side faces 51, 5 of the fibre sliver packages 5a to 5d and the supporting wall 26 are inclined at an angle relative to the vertical. The bundle 5' consisting of the fibre sliver packages 5a to 5d is supported stably for transport and secured against slipping, tipping over or the like, in particular by virtue of its being inclined relative to the vertical, its leaning against the supporting wall 26 and its being supported above the centre of gravity of the bundle 5' or its having a low centre of gravity below the supporting means.

In accordance with the configuration according to Fig. 13 - in which a fork-lift truck 31 according to Fig. 12 or a corresponding transport vehicle is used - there is a transport pallet 25 carrying fibre sliver packages 5a to 5d, which transport pallet is inclined by an angle 6 transversely with respect to the direction of the long- itudinal axes of the fibre sliver packages 5a to 5d, the forks 32a, 32b of the fork-lift truck 31 engaging under the fibre sliver packages 5a to 5d in the direction of the - 26 - longitudinal axes. The forks 32a, 32b are rotatable about a common longitudinal axis which extends in the longitudinal direction thereof.

In accordance with Fig. 14, six draw frames la to if, for example Trützschler TD 03, are arranged in a row one next to the other. At the inlet of each draw frame la to if there is a respective lattice 35 (feed table) with six round cans 36 (positions 35 and 36 for only one draw frame la are shown), from which six fibre slivers to be drafted are each supplied to the drafting mechanism 2 of a respective draw frame la to if. At the outlet of each draw frame la to if, can-less fibre sliver packages 5 are produced in the respective depositing area 10 (see inter alia Fig. 1, 2, 4 and 5). The draw frames la to if are both sliver-fed and sliverdelivering spinning machines.

After the outlet of each draw frame ia to if there is a respective storage device 30a to 30f, to which - from one side - the can-less fibre sliver packages 5 produced in the draw frame la to if are discharged and in which the can-less fibre sliver packages 5 are stored on transport pallets 25. On the respective other side and along the storage devices 30a to 30f there is arranged a rail guide means 37 on which (in accordance with the example shown in Fig. 14) two driven transport vehicles 38a, 38b are moved back and forth in the direction of arrows W1, W2. The storage devices 30a to 30f are by that means so positioned that they lie in a common path for the transport vehicles 38a, 38b. At an end region of the rail guide means 37 (in Fig. 14 in the region after the storage device 30f) there are arranged, transversely with respect to the rail guide means 37, a conveyor device 39, for example a roller conveyor, conveyor belt or the like, for transport pallets loaded with fibre sliver packages 5 (full pallets) and a conveyor device 40, for example a roller belt, conveyor * -27- belt or the like, for empty transport pallets 25 (empty pallets). The conveyor device 39 leads to a press 41 having a binding device 42, downstream of which there are arranged a scales 43 and a labelling device 44. A further conveyor device 45 for forwarding and transporting the bound fibre sliver packages 5, which can consist of a bundle 5' of a plurality of individual fibre sliver packages, is provided.

In the example shown in Fig. 14, the transport vehicle 38a carries two transport pallets 25a, 25b each having a bundle 5', 5' of four can-less fibre sliver packages 5, the transport pallets 25a, 25b having been conveyed out of the storage device 30a and loaded onto the transport vehicle 38a. Accordingly, in the storage device 30a there are two empty storage positions for two empty transport pallets 25'. In each of the storage devices 30b to 30e there are two empty transport pallets 25' for receiving can-less fibre sliver packages 5 or bundles 5'.

In the storage device 30f, two empty storage positions for two empty transport pallets 25' are shown. On the transport vehicle 38b there are arranged two empty pallets 25', 25''. In operation, the transport vehicle 38a travels to one end of the conveyor device 39, where pallets 25a, with the bundles 5', 5'', 25b are loaded one after the other and forwarded to the press 41 in the direction of arrow X. Here the bundles 5', 5'' are provided with base and cover boards (not shown), for example of corrugated cardboard, fibreboard or the like, pressed, bound and - removed from the transport pallets 25 - discharged on the conveyor device 45 in the form of bound bundles. The empty transport pallets 25' separated from the bundles 5' 5'' are conveyed by means of a cross- conveyor 46 to the conveyor device 40 from where they are loaded in direction Y onto one of the transport vehicles 38a or 38b.

In accordance with Fig. 15, at the inlet of a draw frame 1, for example Trützschler TD 03, there is arranged a feed table 35 (lattice) which is associated with two transport pallets 25a, 25b. Four independent can-less fibre sliver packages 5.1 to 5.4 are stably arranged one next to the other on the transport pallet 25a, and four independent can-less fibre sliver packages 5.5 to 5.8 are stably arranged one next to the other on the transport pallet 25b. The fibre sliver packages 5.]. to 5.8 are worked-off individually, that is to say in the case of four fibre sliver packages 5.1 to 5.4 and 5.5. to 5.8 on a transport pallet 25a and 25b there are in each four working-off points. The draw frame 1 is supplied with eight fibre slivers (Cf. fibre slivers 82 in Fig. 20).

Such an arrangement creates a space-optimised version.

In accordance with Fig. 16, upstream of the inlet of the draw frame 1, for example Trützschler TD 03, there is likewise arranged the feed table 35 (lattice) which is associated, however, with eight transport pallets 25a to 25h. On each transport pallet 25a to 25h there are stably arranged one next to the other four can-less fibre sliver packages - for example fibre sliver packages 5.1, 5.2, 5.3, 5.4 on transport pallet 25a - which in the embodiment according to Fig. 11 are joined to one another by their sliver ends. In that way, the fibre sliver packages on a transport pallet, for example fibre sliver packages 5.1, 5.2, 5.3, 5.4 on transport pallet 25a, are unwound one after the other without interruption, bringing the advantage of long sliver run lengths. Where there are four fibre sliver packages on each transport pallet, the run time for a total fibre sliver package is quadrupled. Such an arrangement creates an efficiency- optimjsed version.

In the draw frames la to if shown in Fig. 14, which are sliver-fed and sliver-delivering spinning machines, 1 -29- instead of being supplied with round cans 36 each lattice can be supplied with can-less fibre sliver packages 5, f or example in the maimer shown in Fig. 15 and 16.

According to Fig. 17, the sliver packages produced according to the invention are used in so-called direct spinning. The method of automating the yarn production process, especially in spinning mills having rotorspinning machines, is advantageously based on the use of can-less fibre sliver packages 5 of elongate cross- section. Such a fibre sliver package 5 on an elongate supports 25 can be exactly oriented and stably positioned by readily obtainable means on a selected operating position of the rotor spinning machine. The automatic process of yarn production is controlled by a control centre 50 which determines the exchange of the supports, for example transport palettes 25, under the spinning positions of the rotor-spinning machines 51a to 51d, for example on the basis of the sum of two logic signals - the reaching or exceeding of a predetermined spinning time of a spinning position, so that the spinning operation was interrupted at that spinning position. To optimise the process of exchanging the support 25s, the control centre draws on the knowledge of information relating to the pure spinning time of the individual spinning positions since the last exchange of the support 25 of the spinning position in question. As loading station for the supports 25, the spinning mill has at least one flat card 52a to 52c, for example Trützschler TC 03, each of which contains an integrated drafting system 53a to 53c, for example Trützschler IDF, and a rotary plate 54a to 54c. Each flat card 52a to 52c is associated with a storage device 55a, 55b and 55c for transport pallets 25' loaded with fibre sliver packages 5 and for empty transport pallets 25''.

The storage devices 55a, 55b, 55c can be in the form of belt storage means, for example in the manner shown in Fig. 9. Between the rotor spinning machines 51a to 51d and the storage devices 55a to 55c there is installed in the plane of the floor of the spinning mill an induction loop 56 by means of which the sig-nals from the control centre and the reactions of the sensors from and/or to at least one automatically controlled transport carriage 57, having at least one transport pallet 25 for each of the can-less fibre sliver packages 5, are transmitted.

Reference numeral 58 denotes an intermediate storage means (buffer) for transport pallets 25 having can-less fibre sliver packages 5 and for empty transport pallets 25'. The rotor-spinning machines 51a to 51d are sliver-fed spinning machines.

Fig. 18 shows a flat card 52, for example a flat card of the kind known as TC 03 (Trade Mark), made by Trützschler GmbH & Co. KG, as a sliverdelivering spinning room machine. The card has a feed roller 60, feed table 61, lickers-in 62a, 62b, 62c, cylinder 63, doffer 64, stripper roller 65, nip rollers 66, 67, web guide element 68, web funnel 69, delivery rollers 70, 71 and revolving card top 59. Downstream of the outlet of the flat card 52 there is arranged a sliver-depositing device 72, in which the rotating rotary plate 54 is located in a rotary plate panel 73, above which there is arranged the drafting system 53, for example Trützschler IDF. The fibre sliver 74 produced by the flat card 52 passes by way of a sliver funnel through the drafting system 53, a sliver funnel with delivery rollers, then the sliver channel of the rotary plate 54 and is deposited in the form of a can- less fibre sliver package 5 on a support plate 4, which is moved back and forth horizontally in direction A, B during deposition and after each stroke is lowered in direction E. The fibre sliver package 5 is stably positioned in a manner corresponding to that shown inter alia in Fig. la, lb and 4.

According to Fig. 19, a flyer 75, a sliver-fed spinning room machine, has a spindle and spool device 76, a flyer drafting system 77 and an upstream feed table 35 (lattice). Beneath the lattice 35 there are four can-less fibre sliver packages 5a to 5d, the fibre sliver packages 5a, Sb being stably positioned on a transport pallet 25a and the fibre sliver packages 5c, 5d being stably positioned on a transport pallet 25b.

In accordance with Fig. 20, a combing preparation machine 80, a sliverfed and sliver-delivering spinning room machine, has two feed tables 35a, 35b (lattice) arranged parallel to one another, six transport pallets 25 to 256 carrying stably positioned can-less fibre sliver packages 5i to 56 (only 5 shown) being arranged beneath the feed table 35a and six transport pallets 257 to 2512 carrying stably positioned can-less fibre sliver packages 57 to 512 being arranged beneath the feed table 36a. The feed tables 35a, 36a have a guide pulley 81 above each of the fibre sliver packages 5 to 512. The fibre slivers 82 withdrawn from the fibre sliver packages 5 to 512, after being guided by the guide pulleys 81, pass into two drafting systems 83a, 83b of the combing preparation machine 80 which are arranged one after the other. From the drafting system 83a, the fibre sliver web that has been formed is guided over the web table 84 and, at the outlet of the drafting system 83b, laid one on top of the other with the fibre sliver web produced therein. The two fibre sliver webs are drawn into a downstream drafting system 83c, and the fibre material produced in the drafting system 83c is deposited, using a downstream rotary plate 84, in rings on a substantially rectangular support plate 4 which is movable back and forth in the longitudinal direction to form a can-less fibre sliver package 5. The fibre sliver package 5 is stably positioned in a manner corresponding to that shown in Figures la, lb and 4. The can-less fibre sliver package 5 is then supplied to a combing machine (see Fig. 21) .

According to Fig. 21, a combing machine 90 has six combing heads 91a to 91f arranged in a row one next to the other. Each combing head 91a to 91f is associated with a transport pallet 25 to 256, there being two can-less fibre sliver packages 5i to 512 (only 5 shown) stably positioned on each transport pallet 25 to 256. The fibre slivers 92 that have been deposited in rings are drawn off from the fibre sliver packages 51 to 512 which seen in plan view - are substantially rectangular. For that purpose, above the fibre sliver packages 5 to 512 there is a lattice framework 93 with guide pulleys (see Fig. 20).

The fibre slivers 92 are combed in the combing heads 91a to 91f and supplied by way of the sliver table 94 to a drafting system 95, in whichthe fibre slivers 92 are combined to form a single fibre sliver 96. In the downstream sliver deposition step, a rotary plate 97 deposits the fibre sliver 96 in ring form in the form of a can-less fibre sliver package 5 on a substantially rectangular support plate 4 which is movable back and forth in the longitudinal direction. The fibre sliver package 5 is stably positioned in a manner corresponding to that shown in Figures la, lb and 4. The can-less fibre sliver package is then supplied to a spinning machine or a storage means.

The afore-mentioned components - as well as the fibre sliver packages 5 can, as required, be provided singly or multiply. The component names chosen are also not to be interpreted in the narrow sense of the words, but are to be understood as being synonyms for a certain kind of machine or system component. For example, in the context of the present invention the term "draw frame" 1 represents one or more sliver-delivering or sliver- producing machine(s) to which sliver is supplied from, and/or from which sliver is formed into, can-less sliver packages using the apparatus and/or method of the invention. The fibre sliver packages 5 have a substantially rectangular shape in the configurations shown. Various types of spinning machine can be used as sliver-fed (sliver-processing) spinning room machines, for example ring-spinning or open-end spinning machines, and also draw frames, flyers, combing preparation machines or combing machines, which are supplied with fibre slivers for the production of fibre structures (roving, wound lap, fibre sliver, yarn), from sliver packages provided using the apparatus and/or method of the invention. For the explanation in Fig. 17, an open-end spinning machine has been chosen solely as an exemplary embodiment. The particular construction of the storage devices is, in principle, also of no significance for the present invention; in principle, a storage position for the fibre sliver packages 5 is sufficient for that purpose. The fibre sliver packages 5 produced in the draw frame 1 are preferably arranged as a group on a support by means of which they are always transported back and forth as a complete unit between the individual components of the system. According to the exemplary embodiments shown in Fig. 14 and 17, a plurality of transport vehicles is provided, each of which is able to receive a group of canless fibre sliver packages 5 in the form of a unit which it conveys from the (sliver-delivering or sliver- producing) draw frame 1 to a sliver-processing or sliver- using textile machine for further processing or to intermediate storage. In the exemplary embodiments shown in Fig. 14 and 17, the transport vehicles are in the form of automatic units - the drive means of which is not shown for reasons of clarity of the drawings which can travel along a path between the individual components of the S system. The term "path" or "track" is not to be understood in the narrow sense of the word; it should also include infrared or ultrasonic guide means or the like. If the transport vehicle is steered manually, the terni "path" also includes any kind of route along which the transport vehicle is or can be transported.

In spinning, cans, also called spinning cans, are hollow bodies (containers) which are used for the deposition, housing and removal of fibre slivers. The cans are forwarded, transported, stored and supplied. Such cans are in the form of rectangular cans enclosed on all sides by walls, that is to say having four side walls and a base wall, with the exception of the open upper side, which is used as a filling and removal opening for the fibre sliver. In contrast, the invention relates to canless fibre sliver packages 5, that is to say there are no cans, containers or the like for the fibre sliver. The fibre sliver is deposited, withdrawn, forwarded, stored and supplied in the form of a can- less fibre sliver package 5.

The sliver is deposited onto a surface that is substantially unenclosed and which in particular does not include any partial or full circumferentially extending wall for providing lateral support to the sliver package during deposition. Whilst the sliver package is transported for further processing without the use of a can or other structure having an encircling wall that encloses the sliver package, it is within the scope of the invention for lateral support to be provided during transport of the sliver package away from the depositing area for further processing as will be apparent from Figs. Ia 35- Ba, 9, 12 and 13.

In accordance with the invention, the deposited, collected fibre sliver (referred to herein as a "fibre sliver package") is typically in the form of a collection of deposited rings of sliver arranged in successive layers, and are advantageously in substantially freely deposited form. In the fibre sliver packages, which as mentioned are advantageously in substantially freely deposited form, in addition to being free of any cans or containers, the fibre sliver packages do not require securing by ties, tape or other fastening devices for circu.mferentially retaining the sliver. It is a particular advantage of the invention that the fibre sliver package, in freely deposited form, is of a structure that is sufficiently stable that the fibre sliver package is able to be formed and/or transported and/or delivered to a feed position at a downstream sliver-fed machine substantially without disruption to the fibre sliver package.
