    CROSS-REFERENCE TO RELATED APPLICATIONS
  • This application claims priority of German Application No. 10 2006 012 580.0, filed Mar. 16, 2006. This application is additionally a continuation-in-part of U.S. application Ser. No. 11/247,276, filed Oct. 12, 2005, which application is a continuation-in-part of U.S. application Ser. No. 10/350,016, filed Jan. 24, 2003, (now abandoned), the latter application claiming priority from German Patent Application No. 10205061.9 filed Feb. 7, 2002, which priority is also claimed in the present application. The contents of all of the foregoing applications are incorporated herein by reference in their entirety.
  • BACKGROUND OF THE INVENTION
  • The invention relates to an apparatus on a spinning machine, especially a spinning preparation machine such as a flat card, draw frame, combing machine, integrated drafting system, roller card or the like, for depositing fiber sliver. The machine includes a delivery device (coiler plate) for delivering 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 is substantially unenclosed. The receiving support surface and the delivery device are displaceable relative to one another in a depositing area in which the fibre sliver is depositable. The receiving support surface is movable back and forth horizontally. The delivery is located in a fixed position during delivery of the fibre sliver. The receiving support surface is lowerable vertically during delivery of the fibre sliver.
  • Such an apparatus is known from earlier U.S. application Ser. No. 10/350,016.
  • SUMMARY OF THE INVENTION
  • The aim of the present invention is to improve such an apparatus to the effect that the production of the fibre sliver package is considerably improved. According to one exemplary embodiment, an apparatus on a spinning machine for depositing fibre sliver, comprises: a delivery device comprising a coiler plate adapted to deliver fibre sliver in the form of a can-less fibre sliver package; a substantially planar receiving support surface onto which the fibre sliver is deposited, the receiving support surface being adapted to move back and forth in a deposition area with respect to the delivery device through a substantially horizontal stroke, the receiving support surface also being adapted to move away from the delivery device in a substantially vertical stroke during delivery of the fibre sliver; wherein the delivery device and the receiving support surface are both adapted to remain in contact with the fibre sliver as it is deposited in the form of a can-less fibre sliver package, such that the fibre sliver package is stabilized during the substantially horizontal stroke and during lowering of the receiving support surface.
  • Because the delivery device and the receiving support surface are in contact with the deposited fibre sliver, vertical pressure can be 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 against tipping over during the horizontal back and forth displacement. That stability is important, because the displacement of the sliver package is effected without cans, containers or the like, that is to say there is no support structure for the side and end faces of the sliver package.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Embodiments of the invention are discussed in detail below. In describing embodiments, specific terminology is employed for the sake of clarity. However, the invention is not intended to be limited to the specific terminology so selected. While specific exemplary embodiments are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations can be used without departing from the spirit and scope of the invention. All references cited herein are incorporated by reference as if each had been individually incorporated.
  • FIGS. 1 a and 1 b show an exemplary draw frame 1, for example, a Trützschler draw frame TD 03. A plurality of fibre slivers, coming from an upstream lattice (feed table), enter a drafting system 2, are drafted therein and, after the outlet of the drafting system 2, are 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 to form a can-less fibre sliver package 5. Support plate 4 can have, for example, a rectangular top face 4 1. Referring to FIG. 4, the support plate 4 can be driven by a controllable drive motor 6 which is connected to an electronic control and regulation device 7, for example, a machine controller. Referring back to FIGS. 1 a, 1 b, reference numeral 8 denotes a cover sheet of the sliver-depositing device which is adjoined by the rotary plate 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 comprises the region g in accordance with FIG. 1 b. The support plate 4 is moved horizontally back and forth beneath the rotary plate 3 while the fibre sliver 12 is being deposited. FIG. 1 a shows one end position and FIG. 1 b shows the other end position of the support plate 4 which moves back and forth horizontally in directions 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 directions A, B, in the direction of arrows C, D beneath the rotary plate 3. Once the end position shown in FIG. 1 a 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. 1 b has been reached, the support plate 4 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 jolt-free or nearly jolt-free speed. In particular, the acceleration and the braking are jolt-free or nearly jolt-free. The speed between acceleration and braking is constant. By that, it is meant that the fibre sliver package 5 remains stable both during the back and forth movement in the depositing area 10 according to FIG. 1 a and 1 b and during the movement out of the depositing area 10 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 exemplary 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 delivery force is achieved, among other factors, by delivery 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 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 402 a or 402 b (see FIGS. 3 a, 3 b) of the fibre sliver package 5, and accelerates the support plate 4 whenever the support plate 4 leaves the border region 402 a or 402 b. Between the border regions 402 a and 402 b 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 402 a or 402 b 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.
  • The border region 402 a or 402 b can be 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 402 a or 402 b, the control device 7 brakes the support plate 4 so that more fibre sliver 12 can be deposited in the border region 402 a or 402 b 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 402 a or 402 b, because the rotary plate 3 delivers the fibre sliver 12 at a constant rate irrespective of the movement of the 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 402 a and 402 b and in the non-border region 404 (FIGS. 3 a, 3 b) 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 4 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, as shown in 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. 3 a shows a plan view of a ring-shaped fibre sliver package 5 which has been deposited freely on the top face 4 1 of the support plate 4. FIG. 3 b shows a side view of the fibre sliver package 5 which is arranged freely on the support plate 4. FIG. 3 c shows a front view of the fibre sliver package 5, which has been positioned freely on the support plate 4. As shown in FIGS. 3 a to 3 c, 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 4 1 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 1. The movement of the support plate 4 has the effect that the deposited fibre sliver rings are arranged on the receiving surface 4 1 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. 3 a 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. 3 a shows a plan view of the fibre sliver 12 of the fibre sliver package 5 deposited in a ring arrangement. FIGS. 3 b and 3 c 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 4 1 of the support plate 4. In respect of the dimensions of the fibre sliver package 5, the length according to FIG. 3 a is denoted by reference letter a, the width according to FIG. 3 c by reference letter b and the height according to FIG. 3 c by reference letter c. With regard to the dimensions of the support plate 4, the length according to FIG. 3 a is denoted by reference letter d, the width according to FIG. 3 a by reference letter e and the height according to FIG. 3 c by reference letter f. Reference numeral 5 5 (FIG. 3 a) denotes the upper face, reference numeral 5 1 (FIG. 3 b) a long side face and reference numeral 5 3 (FIG. 3 c) a short end face of the substantially cuboidal fibre sliver package 5 which is of substantially rectangular cross-section. The other long side face 5 2, the other short end face 5 4 and the base surface 5 6 are not shown.
  • According to FIG. 4, there is shown an electronic control and regulation device 7, for example, a machine controller. The electronic control and regulation device 7 can be connected to 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 3. A raising and lowering device is mounted on a carriage 20, which raising and lowering device consists of a framework, guide rollers 18 a, 18 b, and a flexible transport element, which can be moved in the direction of arrows L and M. The vertically displaceable support plate 4 (see arrows E, F in FIG. 1 a) includes two driver elements 15 a, 15 b. Those driver elements 15 a, 15 b, which are arranged on the opposite narrow sides of the support plate 4, rest on support elements 16 a, 16 b, which are attached to perpendicularly arranged flexible transport elements, for example toothed belts 17 a, 17 b circulating around toothed belt wheels. One of the guide rollers 18 a 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 15 a, 15 b lie on the support elements 16 a, 16 b located at the bottom, so that upward displacement of the support elements 16 a, 16 b brings about an upward movement of the driver elements 15 a, 15 b and accordingly of the support plate 4. The transport elements 16 a, 16 b are attached, for example, by means of holding elements 19 a, 19 b of the framework, to the carriage 20, which is moved horizontally back and forth in the direction of arrows O, 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 5 standing on the support plate 4 and being moved back and forth in the direction of arrows A, B (see FIG. 1 a). During the ongoing fibre sliver deposition, the upper fibre sliver rings of the fibre sliver package 5 are constantly in contact with the underside 9 a of the rotary plate panel 9. The deposited fibre sliver 12 of the fibre sliver package 5 presses against the underside 9 a and against the lower cover face 3 a of the rotary plate 3. In order that a pre-determined constant pressing force is exerted vertically on the deposited fibre sliver 12, the control and regulation 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 16 a, 16 b, which are attached to the flexible transport elements 17 a, 17 b, 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 stroke g (see FIG. 1 b) in the horizontal direction, the support plate 4 is displaced downwards by a pre-set amount. This 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 9 a and 3 a 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 stabilized actively and passively during the horizontal back and forth movement.
  • FIG. 4 shows the carriage 20 with the holding devices 19 a, 19 b. The holding elements 19 a, 19 b hold two belts 17 a, 17 b, 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 1 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 (see FIGS. 1 a and b). Once each corresponding end position has been reached, the support plate 4 is displaced downwards in direction E (FIG. 1 a) 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 substantially immediately deposited into. The substantially constant space relates to the region between the upper side of the laterally unsupported fibre sliver package 5 and the base surface 3 a of the rotary plate 3 and produces a constant force pressure 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 of fibre sliver 12 that is deposited onto the fibre sliver package 5 between a pair of movement turn-around points for the support plate 4 (that is to say from one point at which the support plate 4 changes direction to the next subsequent point at which the support plate changes direction). Deposition of the fibre sliver 12 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 the support plate 4 (see arrow E in FIG. 1 a) 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 3 a of the rotary plate 3 and against the base surface 9 a 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 3 a and 9 a 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-compaction of the fibre sliver package 5, which is advantageous for further discharge and further transport of the fibre sliver package 5.
  • FIG. 5 shows a fibre sliver package 5 a 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 5 a is displaced horizontally in direction C, D of its longitudinal axis (see FIG. 1 a), that is to say in the direction of its long side faces. Parallel to and spaced apart from a side face 5 of the sliver package 5 a, there is a fixed side wall 22 a 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. 1 b) (stroke length) is variable by means of the motor 6 (see FIG. 4), so that the length a (see FIG. 3 a) of the fibre sliver package 5 a is adjustable. Downstream of the depositing area 10 there is arranged the discharge region 11 in which a transport pallet 25 can be located. Two fibre sliver packages 5 b, 5 c can be stored one next to the other on the pallet 25.
  • Referring to FIGS. 6 a and 6 b, an exemplary embodiment 4.1 of the support plate 4 is shown. Through-holes 4.1.1 can be arranged in the top face 4 1 of the support plate 4.1. A plate 23 can be arranged on the opposite side of support plate 4.1, and can include conical lugs having tips 23.1. As shown in FIG. 6 a, the tips 23.1 can project through the through holes 4.1.1. The plate 23 can be raised and lowered in the direction of arrows Q1, Q2 (FIG. 6 b) 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. 6 b. According to FIG. 6 a, the tips 23.1 project through the holes 4.1.1 for a short time only 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 1 and does not slide off the top face 4 1. As soon as the layer of fibre sliver is lying stably on the top face 4 1, 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 1 without problems.
  • FIGS. 7 a to 7 c show another exemplary embodiment of a support plate. According to FIGS. 7 a to 7 c, the top face 4 1 of the support plate 4.2 can define longitudinal grooves 4.2.1. As shown in FIG. 7 b, elongate lifting rods 24 a, 24 b or the like can be inserted in direction R1, R2 underneath the lower side of the fibre sliver package 5. In accordance with FIG. 7 c, the lifting rods 24 a, 24 b can be raised in direction S1, S2, with the result that the lower side of the fibre sliver package 5 is lifted away from top face 4 1 of the support plate 4.2, so that the support plate 4.2 can be displaced in direction W underneath the fibre sliver package 5 and without frictional contact with the fibre sliver package 5 (see also FIG. 10 d).
  • According to FIG. 8, the support plate (hidden from view), together with a fibre sliver package 5 d, can be located in the discharge region above the top face 25 1, of the transport pallet 25. Transverse to the longitudinal axis of the fibre sliver packages 5 b, 5 c, that is to say in the direction of their short side or end faces 5 3, 5 4 (shown, e.g., in FIGS. 3 a-3 c), the transport pallet 25 can be inclined at an angle α of, for example, approximately 7° to the horizontal. As shown in FIG. 8 a, on the side face 25 2 of the transport pallet 25 close to the base, there can be mounted a supporting wall 26, for example, a smooth sheet metal wall or the like. The supporting wall 26 can form an angle of about 90° with respect to the top face 25 1, of the transport pallet 25. As a result, the fibre sliver package 5 c can lean against the support wall 26. The adjacent fibre sliver package 5 b can lean against the inclined fibre sliver package 5 c in contact therewith. By virtue of their inclination, the fibre sliver packages 5 b, 5 c are supported stably on the transport pallet 25 and are secured against tipping over and the like. As also shown in FIG. 8 a, the smooth side wall 22 b is displaceable in the direction of arrows T1, T2, so that during the discharge of the fibre sliver package 5 d troublesome frictional contact with the stored fibre sliver package 5 b can be avoided. According to FIG. 8 b, there is shown an exemplary supporting element 98, for example, a perpendicular supporting wall, which can be inclined by about 5 to 10° in the horizontal direction about a pivot bearing 99, in order to incline the discharged fibre sliver package 5 d against the stored and inclined fibre sliver package 5 b. One or more of the supporting walls 22 b, 98 can be adapted to couple and decouple with the receiving support surface (hidden from view).
  • According to FIG. 9, an exemplary storage apparatus is shown in the form of a belt storage. A conveyor belt 29 endlessly circulates around two guide rollers 28 a, 28 b driven by a motor 27. On the upper belt portion 29 1, there are arranged, one after the other in direction U1, and lying horizontally on the belt, an empty transport pallet 25 a, a transport pallet 25 b loaded with a fibre sliver package 5 c, and a transport pallet 25 c fully loaded with four fibre sliver packages 5 b, 5 c, 5 d, 5 e. On one end face 25 2 of each transport pallet 25 a, 25 b, 25 c there is mounted a supporting wall 26 a, 26 b, 26 c or the like, which can be arranged inclined at an angle β of about from 5° to 10° relative to the vertical. By virtue of the inclination of the supporting wall 26, the fibre sliver packages 5 b, 5 c, 5 d, 5 e can be positioned stably on the transport pallets 25 b and 25 c. Each time a fibre sliver package S has been unloaded onto the transport pallet 25 b, the upper belt portion 29 1 moves in direction U1 by the width b (see FIG. 3 c) of a fibre sliver package 5. During or after the loading of the transport pallet 25 b, the already full transport pallet 25 c can be transported away. Once the transport pallet 25 b has been loaded with four fibre sliver packages 5, the upper belt portion 29 1 is moved in direction U1 so that the full transport pallet 25 b moves into the position for being transported away and the empty transport pallet 25 a moves into the (middle) position for discharge of the fibre sliver packages 5. A fresh empty transport pallet (not shown) is then placed on the upper belt portion 29 1.
  • In accordance with FIG. 10 a, 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 5 d, is moved horizontally in direction I and arrives at a position spaced apart by distance h above the top face 25 1 of the transport pallet 25 (see FIG. 10′) and in parallel next to a fibre sliver package 5 c already being stored on the top face 25 1 (FIG. 10 b). A holding-back element 27 is then displaced horizontally in direction V1 from a position outside the transport pallet 25 (FIG. 10 b) to a position in front of the end face 5 4 (see FIG. 10 c) of the fibre sliver package 5 d (by a drive device not shown) and spaced apart by distance i above the top face 4 1 of the support plate 4 (see FIG. 10′). Then, driven by the motor 6, the support plate 4 is moved back alone, without the fibre sliver package 5 d, horizontally in direction J beneath the holding-back element 27 (see FIG. 10 d). In the course of that movement in direction J, the fibre sliver package 5 d, held in place by the holding-back element 27, slides off the smooth surface 4 1 of the support plate 4, so that the fibre sliver package 5 d is removed from the support plate 4. At the same time, as shown in FIG. 10 d, the fibre sliver package 5 d is deposited on the surface 25 1 of the transport pallet 25. The distance h between the lower face 4 2 of the support plate 4 and the upper side 25 1 of the transport pallet 25 (see FIG. 10′) is small, so that when sliding off the support plate 4 the fibre sliver package 5 d is lowered onto the transport pallet 25 without problems. Finally, the holding-back element 27 is moved back horizontally in direction V2 (FIG. 10 e).
  • In the position according to FIG. 10 c, the support plate 4 can be rotated (not shown) about its longitudinal axis through an angle of about from 5° to 10°, so that the fibre sliver package 5 d is inclined in the direction towards and parallel to the side face of the deposited, inclined fibre sliver package 5 c. The rotation of the support plate 4 assists the downward sliding movement of the fibre sliver package 5 d from the top face 4 1.
  • Alternatively (or additionally) a sheet metal wall or the like can be adapted to move horizontally into the region above the transport pallet 25, and incline about its longitudinal axis, causing the fibre sliver package 5 d to incline in the direction towards and parallel to the side face of the fibre sliver package 5.
  • According to FIG. 11, four can-less fibre sliver packages 5 a to 5 d are arranged one next to the other on the top face 25 1 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 5) is joined to the sliver end or the end of the first ring of fibre sliver of a base layer (base surface 5 6) 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 5 5) of fibre sliver package 5 a is joined to the sliver end of the first ring of fibre sliver of the base layer (base surface 5 6) of fibre sliver package 5 b. The same applies to the sliver ends and the joining together thereof in respect of the further fibre sliver packages 5 cand 5 d. In that way, by joining together the sliver ends, a single total fibre sliver package comprising a plurality of individual fibre sliver packages 5 a to 5 d is created. When supplied to and worked off on sliver-fed machines (e.g., those shown in FIGS. 15 to 17 and 19 to 21), all fibre sliver packages of the total fibre sliver package, beginning with the top layer (top face 5 5) of fibre sliver package 5 d, can 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 5 a to 5 d arranged on its top face 25 1. Transverse to the direction of the longitudinal axis of the fibre sliver packages 5 a to 5 d (e.g., parallel to the short end faces of the fibre sliver packages 5 a to 5 d), the transport pallet 25 can be inclined at an angle γ to the horizontal. The correspondingly inclined forks 32 of the fork-lift truck 31 can engage under the transport pallet 25 transverse to the longitudinal axes of the fibre sliver packages 5 a to 5 d. The side faces of the fibre sliver packages 5 a to 5 d and the supporting wall 26 can be inclined at an angle relative to the vertical. The bundle 5′ comprising fibre sliver packages 5 a to 5 d can be supported stably for transport and secured against slipping, tipping over or the like, for example, 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.
  • The exemplary configuration of FIG. 13 can use the fork-lift truck 31 of FIG. 12, or a similar transport vehicle. Transport pallet 25 supports fibre sliver packages 5 a to 5 d. Transport pallet 25 can be inclined by an angle δ transversely with respect to the direction of the longitudinal axes of the fibre sliver packages 5 a to 5 d. The forks 32 a, 32 b of the fork-lift truck (not shown) can engage under the fibre sliver packages 5 a to 5 d in the direction of their longitudinal axes. The forks 32 a, 32 b are rotatable about a common longitudinal axis which extends in the longitudinal orientation thereof.
  • Referring to FIG. 14, six draw frames 1 a to If, for example Trützschler TD 03, can be arranged in a row one next to the other. A lattice 35 (feed table) can be located at the inlet of each draw frame 1 a to 1 f. Each lattice 35 can have six round cans 36. Reference numbers 35 and 36 are shown for draw frame 1 a only. Each set of six round cans 36 can supply six fibre slivers to be drafted to the drafting system 2 (see FIG. 1 a) of a respective draw frame 1 a to 1 f. At the outlet of each draw frame 1 a to 1 f, can-less fibre sliver packages 5 are produced in the respective depositing area 10 (see, e.g., FIGS. 1 a, 1 b, 2, and 5). The draw frames 1 a to 1 f can be both sliver-fed and sliver-delivering spinning machines. After the outlet of each draw frame 1 a to 1 f there can be a respective storage device 30 a to 30 f, to which, from one side, the can-less fibre sliver packages 5 produced in the draw frame 1 a to 1 f 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 30 a to 30 f there can be arranged a rail guide 37 on which (in accordance with the example shown in FIG. 14) two driven transport vehicles 38 a, 38 b are moved back and forth in the direction of arrows W1, W2. The storage devices 30 a to 30 f can be positioned so that they lie in a common path with the transport vehicles 38 a, 38 b. At an end region of the rail guide 37 (for example, in the region to the right of the storage device 30 f in FIG. 14) there can be arranged, transversely with respect to the rail guide 37, a conveyor device 39 (e.g., a roller conveyor, conveyor belt or the like) for transport pallets 25 loaded with fibre sliver packages 5 (full pallets). There can also be a second conveyor device 40 (e.g., a roller belt, conveyor belt or the like) for empty transport pallets 25. The conveyor device 39 leads to a press 41 having a binding device 42, downstream of which there can be arranged scales 43 and a labelling device 44. After that there can be provided 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.
  • In the exemplary embodiment shown in FIG. 14, the transport vehicle 38 a carries two transport pallets 25 a, 25 b each having a bundle 5′, 5″ of four can-less fibre sliver packages 5, the transport pallets 25 a, 25 b having been conveyed out of the storage device 30 a and loaded onto the transport vehicle 38 a. Accordingly, in the storage device 30 a there are two empty storage positions for two empty transport pallets 25′. In each of the storage devices 30 b to 30 e there are two empty transport pallets 25′ for receiving can-less fibre sliver packages 5 or bundles 5′. In the storage device 30 f, two empty storage positions for two empty transport pallets 25′ are shown. On the transport vehicle 38 b there can be arranged two empty pallets 25′, 25″. In operation, the transport vehicle 38 a can travel to one end of the conveyor device 39, where pallets 25 a, 25 b, holding bundles 5′, 5″, are loaded one after the other and forwarded to the press 41 in the direction of arrow X. At the press 41, the bundles 5′, 5″ can be provided with base and cover boards (not shown), for example of corrugated cardboard, fibreboard or the like, pressed, bound, removed from the transport pallets 25, and discharged onto the conveyor device 45 in the form of bound bundles. The empty transport pallets 25′ separated from the bundles 5′, 5″ can be 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 38 a or 38 b.
  • In accordance with the exemplary embodiment of FIG. 15, at the inlet of a draw frame 1, for example a Trützschler TD 03, there can be arranged a feed table 35 (lattice) which can be associated with two transport pallets 25 a, 25 b. Four independent can-less fibre sliver packages 5.1 to 5.4 are stably arranged one next to the other on the transport pallet 25 a, 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 25 b. The fibre sliver packages 5.1 to 5.8 can be worked off individually. For example, in the case of four fibre sliver packages 5.1 to 5.4 and 5.5. to 5.8 on transport pallets 25 a and 25 b, respectively, there can be four working-off points in each case. The draw frame 1 can be supplied with eight fibre slivers (cf. the fibre slivers 82 in FIG. 20). Such an arrangement can create a space-optimised version.
  • In accordance with FIG. 16, upstream of the inlet of the draw frame 1, for example a Trützschler TD 03, there can be arranged the feed table 35 (lattice) which can be associated with eight transport pallets 25 a to 25 h. On each transport pallet 25 a to 25 h there can be stably arranged one next to the other four can-less fibre sliver packages, for example fibre sliver packages 5.1 on transport pallet 25 a. In accordance with the exemplary embodiment shown in FIG. 11, the packages 5.1 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 on transport pallet 25 a, 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 can optimize efficiency.
  • Reverting to FIG. 14, the draw frames 1 a to 1 f shown there may be sliver-fed and sliver-delivering spinning machines, and instead of being supplied with round cans 36, each lattice 35 may be supplied with can-less fibre sliver packages 5, for example in the manner shown in FIGS. 15 or 16.
  • Referring to FIG. 17, the apparatus according to the invention can be used in so-called direct spinning. The method of automating the yarn production process, especially in spinning mills having rotor-spinning machines, can advantageously be based on the use of can-less fibre sliver packages having elongate cross-sections. Such a fibre sliver package can be precisely and stably positioned on an elongated support (e.g., support 25 described previously) in a selected operating position of the rotor-spinning machine by readily available means. The automatic process of yarn production can be controlled by a control centre 50 which determines the appropriate time for exchange of the supports, for example, transport pallets 25, under the spinning positions of the rotor-spinning machines 51 a to 51 d. For example, the control centre 50 can operate on the basis of the sum of two logic signals. The logic signals can represent, for example, the reaching or exceeding of a predetermined spinning time of a spinning position, so that the spinning operation can be interrupted at that spinning position. To optimise the process of exchanging the supports 25, the control centre 50 can draw on the knowledge of information relating to the pure spinning time of the individual spinning positions since the last exchange of the supports 25 of the spinning position in question.
  • As the loading station for the supports 25, the spinning mill can have at least one flat card 52 a to 52 c, for example a Trützschler TC 03. Each flat card can contain an integrated drafting system 53 a to 53 c, for example a Trützschler IDF, and a rotary plate 54 a to 54 c. Each flat card 52 a to 52 c can be associated with a storage device 55 a, 55 b, 55 c for transport pallets loaded with fibre sliver packages, and for empty transport pallets. The storage devices 55 a, 55 b, 55 c can be in the form of belt storage means, for example, in the manner shown in FIG. 9. Between the rotor-spinning machines 51 a to 51 d and the storage devices 55 a to 55 c there can be installed in the plane of the floor of the spinning mill an induction loop 56. The signals from the control centre 50 and the reactions of the sensors from and/or to at least one automatically controlled transport carriage 57 can be transmitted by the induction loop. The transport carriage 57 can have at least one transport pallet 25 for each of the can-less fibre sliver packages 5. Reference numeral 58 denotes an intermediate storage means (buffer) for transport pallets having can-less fibre sliver packages and for empty transport pallets. The rotor-spinning machines 51 a to 51 d are sliver-fed spinning machines.
  • FIG. 18 shows the flat card 52, for example, a Trützschler flat card TC 03, as a sliver-delivering spinning room machine, having a feed roller 60, feed table 61, lickers-in 62 a, 62 b, 62 c, 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 can be 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, a Trützschler IDF. The fibre sliver 74 produced by the flat card 52 can pass by way of a sliver funnel through the drafting system 53, through a sliver funnel with delivery rollers, then through the sliver channel of the rotary plate 54, and is ultimately deposited in the form of a can-less fibre sliver package 5 on a support plate 4. The support plate 4 can be moved back and forth horizontally in directions A, B during deposition. The support plate can be lowered in direction E after each stroke. The fibre sliver package 5 can be stably positioned in a manner corresponding to that shown previously, for example, in FIGS. 1 a, 1 b, and 4.
  • FIG. 19 shows a flyer 75 (a sliver-fed spinning room machine) having 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 5 a to 5 d, the fibre sliver packages 5 a, 5 b being stably positioned on a transport pallet 25 a and the fibre sliver packages 5 c, 5 d being stably positioned on a transport pallet 25 b.
  • Referring to FIG. 20, a combing preparation machine 80 (a sliver-fed and sliver-delivering spinning room machine) has two feed tables 35 a, 35 b (lattice) arranged parallel to one another. The combing preparation machine also has six transport pallets 25 1 to 25 6 carrying stably positioned can-less fibre sliver packages 5 1 to 5 6 (only 5 1 shown) being arranged beneath the feed table 35 a, and six transport pallets 25 7 to 25 12 carrying stably positioned can-less fibre sliver packages 5 7 to 5 12 (not shown) being arranged beneath the feed table 35 b. The feed tables 35 a, 35 b can have a guide pulley 81 above each of the fibre sliver packages 5 1 to 5 12. The fibre slivers 82 withdrawn from the fibre sliver packages 5 1 to 5 12, after being guided by the guide pulleys 81, can pass into two drafting systems 83 a, 83 b of the combing preparation machine 80. The drafting systems 83 a, 83 b can be arranged one after the other. From the drafting system 83 a, the fibre sliver web that has been formed is guided over the web table 84 and, at the outlet of the drafting system 83 b, 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 83 c, and the fibre material produced in the drafting system 83 c 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 can be stably positioned in a manner corresponding to that shown previously, for example, in FIGS. 1 a, 1 b and 4. The can-less fibre sliver package 5 can then be supplied to a combing machine (see FIG. 21).
  • Referring to FIG. 21, a combing machine 90 has six combing heads 91 a to 91 f arranged in a row one next to the other. Each combing head 91 a to 91 f can be associated with a transport pallet 25 1 to 25 6, there being two of the can-less fibre sliver packages 5 1 to 5 12 (only 5 1 illustrated) stably positioned on each transport pallet 25 1, to 25 6. The fibre slivers that have been deposited in rings are withdrawn from the fibre sliver packages 5 1 to 5 12 which, when seen in plan view, are substantially rectangular. For that purpose, above the fibre sliver packages 5 1 to 5 12 there is a lattice framework 93 with guide pulleys (see FIG. 20). The fibre slivers 92 are combed in the combing heads 91 a to 91 f and supplied by way of the sliver table 94 to a drafting system 95, in which the fibre slivers 92 are combined to form a single fibre sliver 96. In the down-stream 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 can be stably positioned in a manner corresponding to that shown previously, for example, in FIGS. 1 a, 1 b, and 4. The can-less fibre sliver package can then be supplied to a spinning machine or a storage means.
  • The afore-mentioned components, as well as the fibre sliver packages 5, can be provided singly or multiply, as required. The component names used herein are 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” represents one or more sliver-delivering or sliver-producing machine(s). The fibre sliver packages 5 have a substantially rectangular shape in the configurations shown. Various kinds of spinning machines can be used as sliver-fed (sliver-processing) spinning machines, for example, ring-spinning or open-end spinning machines, but 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). 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 can be provided, each of which is able to receive a group of can-less 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-consuming textile machine for further processing or to intermediate storage. In the exemplary embodiments shown in FIGS. 14 and 17, the transport vehicles are in the form of automatic units, the drive means of which are not shown for reasons of clarity of the drawings, which can travel along a path between the individual components of the system. The term “path” or “track” is not to be understood in the narrow sense of the word; it is intended also to include infrared or ultrasonic guide means or the like. If the transport vehicle is steered manually, the term “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 can be used for the deposition, housing, and removal of fibre slivers. The cans can be forwarded, transported, stored, and supplied. Such cans can be 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 can-less 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 embodiments illustrated and discussed in this specification are intended only to teach those skilled in the art the best way known to the inventors to make and use the invention. Nothing in this specification should be considered as limiting the scope of the invention. All examples presented are representative and non-limiting. The above-described embodiments of the invention may be modified or varied, without departing from the invention, as appreciated by those skilled in the art in light of the above teachings. It is therefore to be understood that the invention may be practiced otherwise than as specifically described.
