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.
- The invention relates to an apparatus in a spinning room for providing a can-less fiber sliver package (feed material) for a sliver-fed spinning machine, such as a draw frame, flyer, combing preparation machine, combing machine, spinning machine.
- In earlier U.S. application Ser. No. 10/350,016 there is disclosed an apparatus in which from an upstream sliver-delivering spinning machine, for example a draw frame, or from an upstream storage means, the can-less fiber sliver package can be supplied to the sliver-fed spinning machine by a transport device.
- It is an aim of the present invention to improve such an apparatus to the effect that fiber sliver (feed material) can be made available in a simple manner.
- The invention provides an apparatus in a spinning room for making available at least one fiber sliver package to a sliver-fed machine having at least one feed position, comprising a transport arrangement for transporting one or more fiber sliver packages from an upstream sliver-delivering machine or a storage station to a said sliver-fed machine, wherein the transport arrangement is arranged to supply at least one said fiber sliver package to a said feed position and the fiber sliver package(s), the sliver package being stably positioned at said feed position.
- By means of the measures taken according to the invention, fiber material (feed material) is made available to a sliver-fed spinning room machine in a simpler and significantly more efficient manner. A particular advantage is obtained by the arrangement of, for example, four fiber sliver packages on a support, for example a pallet. The arrangement of the fiber sliver packages immediately adjacent to one another on the support, without cans, saves a considerable amount of space. If the ends of adjacent fiber sliver packages are joined together, a large package consisting of four individual packages is obtained on each pallet, which enables processing efficiency to be optimized.
- Advantageously, the transport arrangement comprises at least one transport device and at least one support, wherein a said transport device is arranged for common transport of at least one said support, and at least one stably positioned fiber sliver package received on said support.
- Advantageously, the fiber sliver package is supported on the transport device for example on a said support (e.g. transport pallet). Advantageously, more than one fiber sliver package is supported on the transport pallet. Advantageously, the number of fiber sliver packages, preferably 3, 4, 6 or 8, on the transport device, for example on a transport pallet, corresponds to the number of fiber sliver packages to be supplied to the downstream processing device.
- Advantageously, the support, for example a transport pallet, is associated with a supporting element, for example a supporting wall, mounted on one side. Advantageously, the supporting element is associated with a side face of the first deposited fiber sliver package. Advantageously, the supporting element is in fixed position. Advantageously, the supporting element is mounted on the support, for example a transport pallet. Advantageously, the supporting element is in the form of walls, rods, transport belts or the like. Advantageously, the supporting element consists of, or is coated with, a material that promotes sliding. Advantageously, the supporting element, for example a supporting wall or the like, is inclinable by, or is inclined by, about from 5 to 10°. Advantageously, the support, for example a transport pallet, is inclinable or is inclined by an angle preferably of from 5 to 10°.
- Advantageously, the support, for example a transport pallet, has on its underside insertion openings for transport apparatus and/or for coupling to transport apparatus, for example fork-lift trucks.

- Advantageously, there is in each case an empty storage position on which a fiber sliver package is positionable. Advantageously, there is in each case at least one empty storage position for fiber sliver packages to be supplied. Advantageously, a support, for example a transport pallet, provided with deposited fiber sliver packages is transportable to a further textile machine, for example a spinning room machine, or to a storage means. The transport may be effected partly manually.
- The transport arrangement preferably comprises a mobile transport apparatus, especially a transport vehicle. Advantageously, the transport apparatus is track-guided, for example by means of an induction loop or the like, or is rail-guided. The transport apparatus may instead be freely movable. Advantageously, the support provided (loaded) with deposited fiber sliver packages is positionable directly on a transport apparatus. Advantageously, the transport apparatus is a wagon or the like, or a fork-lift truck or the like. Advantageously, the transport apparatus is drivable back and forth by means of drive means, for example a drive motor.
- Advantageously, displacement of the fiber sliver bundle onto and off the support is effected by pushing.
- Advantageously, the sliver ends of the fiber sliver packages are joinable to one another. Advantageously, the sliver ends of the fiber sliver packages are positioned for joining. The sliver ends may be joinable to one another manually. Instead, the sliver ends may be joinable to one another by means of a device. Advantageously, in the case of fiber sliver packages that are arranged one next to the other, one after the other, the sliver end of the lowermost layer of one fiber sliver package is joinable to the sliver end of the uppermost layer of the other (adjacent) fiber sliver package. By joining together the sliver ends, a single total fiber sliver package consisting of a plurality of individual fiber sliver packages can advantageously be created.
- Advantageously, at least one side element, for example a wall or the like, associated with the transport device is inclinable by, or is inclined by, about from 5 to 10°. Preferably the apparatus is a can-less apparatus. Advantageously, in respect of the fiber sliver package the transport to a subsequent processing device or to a storage means is effected without cans, containers or the like. Advantageously, the fiber sliver package is movable by mechanical means, which effects the displacement of the fiber sliver package into the feed positions without additional cans, containers or the like. Advantageously, the mechanical means is a pressure device, for example a slider or the like.
- Advantageously, the fiber sliver is deposited by a sliver delivering machine in ring form to form fiber sliver packages. Advantageously, the sliver bundle is movable horizontally. Advantageously, the fiber sliver package is transported onto a support. Advantageously, the transport arrangement comprises a conveyor device, for example a belt conveyor, suspended conveyor or the like associated with one or more supports for the fiber sliver packages.
- Advantageously, the fiber sliver package is displaceable in jolt-free or substantially jolt-free manner during deposit of sliver to form a fiber sliver package and/or during transport thereof. Advantageously, the alteration in the speed of the displacement device on the acceleration and deceleration paths 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 open-loop and closed-loop control device. Advantageously, the driven displacement device is able to effect stable displacement of the fiber sliver package.
- Advantageously, the fiber sliver package is can-less. Advantageously, the fiber sliver package is elongate in cross-section. Advantageously, there is a supporting wall or the like which is able to support the fiber sliver package during displacement thereof onto the support and/or a side element associated with the support, which supporting wall or the like and/or side element is inclinable or inclined about a horizontal axis.
- Advantageously, the fiber sliver package is displaceable in a stably supported state. Advantageously, the fiber sliver package is supportable at the center of gravity or above the center of gravity. As mentioned, the transport arrangement may have a support, for example a transport pallet, for receiving the can-less fiber sliver package. Advantageously, the support and an associated supporting element are approximately L-shaped. Advantageously, the support can be elevated on the side remote from the supporting element. Advantageously, a pneumatic cylinder or the like can be used for elevation. Advantageously, as a result of the elevation, the fiber sliver package, inclinable against the supporting element and/or against a further fiber sliver package, is transferable into a stable position. Advantageously, the support is a standard pallet.
- Advantageously, a number of fiber sliver packages appropriate to further processing is transportable together on the support, for example a transport pallet. Advantageously, a transport device is provided for common transport of the support, for example a transport pallet, and at least one stably positioned fiber sliver package.
- Advantageously, a plurality of processing devices, for examples machines, and/or storage means can be served by a transport arrangement comprising a rail- or track-guided, or freely movable transport device. Advantageously, the processing devices, for example machines, and/or storage means are so positioned that they are arranged along a common path for the transport device. Advantageously, the transport of the support, for example a transport pallet, to one or more feed positions (unwinding positions) provided on the further processing machines is effected. Advantageously, the feed position is selected from the lattice (feed table) of a draw frame, the lattice of a flyer, and the lattice of a combing preparation machine. Advantageously, the feed position is the spinning position of a spinning machine (direct spinning).
- Advantageously, the fiber sliver packages are provided with an identification mark, for example a barcode, color marker or the like. The identification mark relates to the production conditions, the fiber material quality, or to test values. Advantageously, the identification mark allows a mixture of fiber sliver packages to be assembled at the feed positions. Advantageously, the assembly of fiber sliver packages to form a mixture can be effected at feed positions. The processing of the fiber sliver packages on the sliver-fed spinning machine can be effected individually. Instead, the processing of a plurality of fiber sliver packages present on a support can be effected simultaneously. Advantageously, the number of working-off points (sliver-detachment points) corresponds to the number of fiber sliver packages on a support, for example a transport pallet. Advantageously, the fiber sliver packages are processed one after the other, the ends of adjacent fiber sliver packages being joined together. Advantageously, processing one after the other is effected without interruption. Advantageously, in the case of a plurality of fiber sliver packages arranged on a support, some are processed individually and some are processed one after the other. Advantageously, in the case of direct spinning fiber sliver packages at the feed positions are exchanged individually. Advantageously, in the case of direct spinning fiber sliver packages at the feed positions are exchanged in blocks, for example four fiber sliver packages on one support (transport pallet). Advantageously, the number of fiber sliver packages is selectable so that they can in each case be matched to the way in which the sliver-fed spinning machines are distributed.
- The invention also provides an apparatus in a spinning room for providing a can-less fiber sliver package (feed material) for a sliver-fed spinning machine, for example a draw frame, flyer, combing preparation machine, combing machine, or spinning machine, in which from an upstream sliver-delivering spinning machine, for example a draw frame, or from an upstream storage means, the can-less fiber sliver package can be supplied to the sliver-fed spinning machine by a transport device, wherein at least one can-less fiber sliver package can be supplied to the feed positions of the sliver-fed spinning machine and stably positioned at the feed positions.
- Moreover, the invention provides a transport system in a textile fiber processing installation, for transporting at least one can-less fiber sliver package along a predetermined path within the textile fiber processing installation between a can-less fiber sliver package delivery station and a sliver-fed machine, the transport system comprising a transport device adapted to receive can-less fiber sliver packages from the fiber sliver package delivery station, carry the received can-less fiber sliver package(s) in a stably positioned manner and to deliver those can-less fiber sliver packages to the sliver-fed machine, and the transport system being adapted to deliver the fiber sliver package(s) to a feed location of the sliver-fed machine in such a manner that the fiber sliver package(s) are stably positioned during taking-off of sliver therefrom by the sliver-fed machine.

FIGS. 1 a and 1 b show anexemplary draw frame 1, for example, a Trützschler draw frame TD 03. A plurality of fiber slivers, coming from an upstream lattice (feed table), enter adrafting system 2, are drafted therein and, after the outlet of thedrafting system 2, are combined to form afiber sliver 12. Thefiber sliver 12 passes through arotary 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-lessfiber sliver package 5.Support plate 4 can have, for example, a rectangulartop face 4 1. Referring toFIG. 4 , thesupport plate 4 can be driven by acontrollable drive motor 6 which is connected to an electronic control and regulation device 7, for example, a machine controller. Referring back toFIGS. 1 a, 1 b,reference numeral 8 denotes a cover sheet of the sliver-depositing device which is adjoined by therotary plate panel 9. K denotes the working direction (flow of fiber material) inside thedraw frame 1, while the fiber sliver is delivered by therotary plate 3 substantially in the vertical direction.Reference numeral 10 denotes the depositing area,reference numeral 11 denotes the region outside the depositingarea 10. The depositingarea 10 for the fiber sliver comprises the region g in accordance withFIG. 1 b. Thesupport plate 4 is moved horizontally back and forth beneath therotary plate 3 while thefiber sliver 12 is being deposited.FIG. 1 a shows one end position andFIG. 1 b shows the other end position of thesupport plate 4 which moves back and forth horizontally in directions A, B beneath therotary plate 3 during deposition of thefiber sliver 12. Thefiber sliver package 5 is moved back and forth, corresponding to directions A, B, in the direction of arrows C, D beneath therotary plate 3. Once the end position shown inFIG. 1 a has been reached, thesupport plate 4 travels in the direction of arrow A, thesupport plate 4 being accelerated, driven at a constant speed and then braked. Once the end position shown inFIG. 1 b has been reached, thesupport plate 4 travels back in the direction of arrow B, thesupport 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 (seeFIG. 4 ). - The variable-speed
electric motor 6 drives thesupport 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 thefiber sliver package 5 remains stable both during the back and forth movement in the depositingarea 10 according toFIG. 1 a and 1 b and during the movement out of the depositingarea 10 according toFIG. 2 . The movements are so controlled that the production rate achieved is as high as possible, without the fiber sliver package 5 (sliver bundle) slipping or even tipping over. - While the
fiber sliver 12 is being deposited, the control device 7 (seeFIG. 4 ) controls the back and forth movement of thesupport plate 4 in order to produce a stable can-lessfiber sliver package 5. In accordance with one exemplary embodiment, therotary plate 3 rotates in a fixed position and deposits thefiber sliver 12 on thesupport plate 4 at a substantially constant deposition force. The constant delivery force is achieved, among other factors, by delivery of a constant amount offiber sliver 12 per fiber material layer of thefiber sliver 12. If, for example, therotary plate 3deposits fiber sliver 12 on thesupport plate 4 or on top of already deposited fiber sliver rings, each layer of fiber sliver rings receives a substantially constant amount offiber sliver 12 either during the forward movement or during the backward movement. Because the amount offiber sliver 12 per layer is constant, stability of thefiber 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 thefiber sliver package 5. Whenever thesupport plate 4 reaches the turn-round point of either the forward or backward movement, the control means 7 brakes thesupport plate 4, thesupport plate 4 reaching aborder region FIGS. 3 a, 3 b) of thefiber sliver package 5, and accelerates thesupport plate 4 whenever thesupport plate 4 leaves theborder region border regions fiber sliver package 5, the control means 7 controls thesupport plate 4 at a constant speed. Theborder region fiber sliver package 5 where the fiber sliver rings deposited on thesupport plate 4 do not completely overlap one another. - The
border region support plate 4 at each end of thefiber sliver package 5. In contrast, in thenon-border region 404, either during the forward or return movement of thesupport plate 4, the rearward edge of each fiber sliver ring is also arranged from above on the forward edge of the previously deposited fiber band ring. - With regard to the small amount of fiber sliver that is deposited in the
border region support plate 4 so thatmore fiber sliver 12 can be deposited in theborder region support plate 4 to a constant speed in thenon-border region 404. The braking of thesupport plate 4 results in an increase in the amount of fiber sliver deposited in theborder region rotary plate 3 delivers thefiber sliver 12 at a constant rate irrespective of the movement of thesupport plate 4. Whenever thesupport plate 4 is braked,more fiber sliver 12 can be deposited at that point, which corresponds to the non-overlapping fiber sliver rings close to the turn-round points. The non-uniform speed of thesupport plate 4 allows a substantially uniform amount offiber sliver 12 which is deposited in bothborder regions FIGS. 3 a, 3 b) of thefiber sliver package 5 for each layer offiber sliver 12 during the back and forth movement of thesupport plate 4. The non-uniform speed of thesupport plate 4 results in a substantially uniform density offiber sliver 12 at all points of thefiber sliver package 5. The uniform density of thefiber sliver 12 enables thefiber sliver package 5 to be formed stably on thesupport surface 4 and allows thefiber sliver package 5 to be accelerated and braked forwards and backwards, avoiding the possibility of the can-less laterally unsupportedfiber sliver package 5 becoming unstable or at risk of tipping over. - After the deposition of the
fiber sliver package 5 on thesurface 4 is complete, as shown inFIG. 2 , thesupport plate 4, together with thefiber sliver package 5, moves out of the sliver delivery device in the direction of arrow I. The control means 7 controls the movement of thesupport 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 depositingarea 10 into thedischarge region 11. -
FIG. 3 a shows a plan view of a ring-shapedfiber sliver package 5 which has been deposited freely on thetop face 4 1 of thesupport plate 4.FIG. 3 b shows a side view of thefiber sliver package 5 which is arranged freely on thesupport plate 4.FIG. 3 c shows a front view of thefiber sliver package 5, which has been positioned freely on thesupport plate 4. As shown inFIGS. 3 a to 3 c, thefiber sliver package 5 is formed from fiber sliver rings stacked in a substantially rectangular shape. The rectangular shape of thefiber sliver package 5 is created by the way in which thefiber sliver 12 has been deposited. The rotation of therotary plate 3 by which thefiber sliver 12 is delivered forms a layer of overlapping rings offiber sliver 12 on a receivingsurface 4 1 of thesupport plate 4, and the back and forth movement of thesupport plate 4 under the control of the control device 7 establishes the locations at which the fiber sliver rings are formed on the receivingsurface 4 1. The movement of thesupport plate 4 has the effect that the deposited fiber sliver rings are arranged on the receivingsurface 4 1 of thesupport plate 4 staggered relative to one another and partly overlapping one another, which creates the substantially rectangular shape of thefiber sliver package 5, seen in plan view. At each end of thefiber sliver package 5, caused by the change in the direction of the back and forth movement of thesupport plate 4, thefiber sliver package 5 has rounded ends to the rectangular shape, asFIG. 3 a clearly shows. The rectangular shape of thefiber sliver package 5 is advantageous, because, as compared with conically or cylindrically shaped fiber sliver packages, it promotes the stability of thefiber sliver package 5. -
FIG. 3 a shows a plan view of thefiber sliver 12 of thefiber sliver package 5 deposited in a ring arrangement.FIGS. 3 b and 3 c show in side view and in front view, respectively, thefiber sliver package 5 standing freely, that is to say without a can, container or the like, on theupper face 4 1 of thesupport plate 4. In respect of the dimensions of thefiber sliver package 5, the length according toFIG. 3 a is denoted by reference letter a, the width according toFIG. 3 c by reference letter b and the height according toFIG. 3 c by reference letter c. With regard to the dimensions of thesupport plate 4, the length according toFIG. 3 a is denoted by reference letter d, the width according toFIG. 3 a by reference letter e and the height according toFIG. 3 c by reference letter f.

The otherlong side face 5 2, the othershort end face 5 4 and thebase 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 acontrollable drive motor 6 for the horizontal displacement of thesupport plate 4, acontrollable drive motor 13 for the vertical displacement of thesupport plate 4, and acontrollable drive motor 14 for therotary plate 3. A raising and lowering device is mounted on acarriage 20, which raising and lowering device consists of a framework, guiderollers FIG. 1 a) includes twodriver elements driver elements support plate 4, rest onsupport elements toothed belts guide rollers 18 a is driven by amotor 13. Themotor 13 is in the form of a reversible motor, which can run at different speeds and in both directions of rotation. On arrival of anempty support plate 4, thedriver elements support elements support elements driver elements support plate 4. Thetransport elements elements carriage 20, which is moved horizontally back and forth in the direction of arrows O, P by a circulatingtransport element 21, for example a toothed belt circulating around toothed belt wheels. - The
rotary plate 3 held by the fixedrotary plate panel 9deposits fiber sliver 12 on thesupport plate 4, the resultingfiber sliver package 5 standing on thesupport plate 4 and being moved back and forth in the direction of arrows A, B (seeFIG. 1 a). During the ongoing fiber sliver deposition, the upper fiber sliver rings of thefiber sliver package 5 are constantly in contact with theunderside 9 a of therotary plate panel 9. The depositedfiber sliver 12 of thefiber sliver package 5 presses against theunderside 9 a and against thelower cover face 3 a of therotary plate 3. In order that a pre-determined constant pressing force is exerted vertically on the depositedfiber sliver 12, the control and regulation device 7 regulates the speed of themotor 13 so that the force exerted by the uppermost layer of thefiber sliver 12 remains constant. In other words, the speed of themotor 13 is such that the rate (amount) of downward movement of thesupport elements flexible transport elements rotary plate 3 driven by themotor 14 ensures uniform compression of thefiber sliver 12 in each height position of the downwardly movingsupport plate 4. After each stroke g (seeFIG. 1 b) in the horizontal direction, thesupport 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 fiber sliver. The can-lessfiber sliver package 5 is pressed against the lower faces 9 a and 3 a of therotary plate panel 9 and therotary plate 3 during the horizontal back and forth movement as a consequence of the resilience inherent in thefiber sliver 12 and as a consequence of the pressing force of thedisplaceable support plate 4. Thefiber sliver package 5 is accordingly stabilized actively and passively during the horizontal back and forth movement. -
FIG. 4 shows thecarriage 20 with the holdingdevices elements belts support plate 4 upwards or downwards in the direction of arrows L, M. The can-lessfiber sliver package 5 is arranged on thetop face 4 1 of thesupport plate 4. During fiber sliver deposition, thesupport plate 4 is moved back and forth in the direction of arrows A, B (seeFIGS. 1 a and 1 b). Once each corresponding end position has been reached, thesupport plate 4 is displaced downwards in direction E (FIG. 1 a) by less than the thickness of a fiber sliver, for example, 10 mm, with the aid of thedrive motor 13, in order to create a substantially constant space (or room) for the next layer of fiber sliver material to be substantially immediately deposited into. The substantially constant space relates to the region between the upper side of the laterally unsupportedfiber sliver package 5 and thebase surface 3 a of therotary plate 3 and produces a constant force pressure per deposited fiber sliver layer. The substantially constant space allows only substantially constant room forfiber sliver 12 deposited for each fiber sliver layer. A fiber sliver layer represents the amount offiber sliver 12 that is deposited onto thefiber 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 thesupport plate 4 changes direction to the next subsequent point at which the support plate changes direction). Deposition of thefiber sliver 12 in the substantially constant space allows a substantially constant density offiber sliver 12 at all locations within thefiber sliver package 5, which promotes the stability of thefiber 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 thefiber sliver 12 constantly flowing in from therotary plate 3. During sliver deposition, the upper side of thefiber sliver package 5 presses, with no spacing, against thebase surface 3 a of therotary plate 3 and against thebase surface 9 a of therotary plate panels 9. There is constant contact. The deposited fiber sliver mass of thefiber sliver package 5 is pressed against the lower faces 3 a and 9 a as a consequence of the resilience inherent in thefiber sliver 12 and as a consequence of the biasing force of thedisplaceable support plate 4. At the same time, this results in pre-compaction of thefiber sliver package 5, which is advantageous for further discharge and further transport of thefiber sliver package 5. -
FIG. 5 shows afiber sliver package 5 a on asupport plate 4 during sliver deposition in the depositingarea 10.Reference numeral 20 denotes the carriage (guide device, holding device) which is movable back and forth horizontally. Thefiber sliver package 5 a is displaced horizontally in direction C, D of its longitudinal axis (seeFIG. 1 a), that is to say in the direction of its long side faces. Parallel to and spaced apart from aside face 5 of thesliver package 5 a, there is a fixedside wall 22 a which is independent of thecarriage 20 and prevents any falling fiber material or the like from entering the machine. The length of the path g (seeFIG. 1 b) (stroke length) is variable by means of the motor 6 (seeFIG. 4 ), so that the length a (seeFIG. 3 a) of thefiber sliver package 5 a is adjustable. Downstream of the depositingarea 10 there is arranged thedischarge region 11 in which atransport pallet 25 can be located. Twofiber sliver packages pallet 25. - Referring to
FIGS. 6 a and 6 b, an exemplary embodiment 4.1 of thesupport plate 4 is shown. Through-holes 4.1.1 can be arranged in thetop face 4 1 of the support plate 4.1. Aplate 23 can be arranged on the opposite side of support plate 4.1, and can include conical lugs having tips 23.1. As shown inFIG. 6 a, the tips 23.1 can project through the through holes 4.1.1. Theplate 23 can be raised and lowered in the direction of arrows Q1, Q2 (FIG. 6 b) so that when theplate 23 is lowered in direction Q2 the tips 23.1 become disengaged from the holes 4.1.1 according toFIG. 6 b. According toFIG. 6 a, the tips 23.1 project through the holes 4.1.1 for a short time only at the start of fiber sliver deposition, so that the first layer of fiber sliver deposited is held on the regularly smoothtop face 4 1 and does not slide off thetop face 4 1. As soon as the layer of fiber sliver is lying stably on thetop face 4 1, the tips 23.1 are lowered out of engagement in direction Q2, so that at a later stage during discharge thefiber sliver package 5 can slide down from thetop face 4 1 without problems. -
FIGS. 7 a to 7 c show another exemplary embodiment of a support plate. According toFIGS. 7 a to 7 c, thetop face 4 1 of the support plate 4.2 can define longitudinal grooves 4.2.1. As shown inFIG. 7 b, elongate liftingrods fiber sliver package 5. In accordance withFIG. 7 c, the liftingrods fiber sliver package 5 is lifted away fromtop face 4 1 of the support plate 4.2, so that the support plate 4.2 can be displaced in direction W underneath the fiber sliver package S and without frictional contact with the fiber sliver package 5 (see alsoFIG. 10 d). - According to
FIG. 8 , the support plate (hidden from view), together with afiber sliver package 5 d, can be located in the discharge region above thetop face 25 1 of thetransport pallet 25. Transverse to the longitudinal axis of thefiber sliver packages FIGS. 3 a-3 c), thetransport pallet 25 can be inclined at an angle α of, for example, approximately 7° to the horizontal. As shown inFIG. 8 a, on theside face 25 2 of thetransport pallet 25 close to the base, there can be mounted a supportingwall 26, for example, a smooth sheet metal wall or the like. The supportingwall 26 can form an angle of about 90° with respect to thetop face 25 1 of thetransport pallet 25. As a result, thefiber sliver package 5 c can lean against thesupport wall 26. The adjacentfiber sliver package 5 b can lean against the inclinedfiber sliver package 5 c in contact therewith. By virtue of their inclination, thefiber sliver packages transport pallet 25 and are secured against tipping over and the like. As also shown in FIG. 8 a, thesmooth side wall 22 b is displaceable in the direction of arrows T1, T2, so that during the discharge of thefiber sliver package 5 d troublesome frictional contact with the storedfiber sliver package 5 b can be avoided. According toFIG. 8 b, there is shown an exemplary supportingelement 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 dischargedfiber sliver package 5 d against the stored and inclinedfiber sliver package 5 b. One or more of the supportingwalls - According to
FIG. 9 , an exemplary storage apparatus is shown in the form of a belt storage. Aconveyor belt 29 endlessly circulates around twoguide rollers motor 27. On theupper belt portion 29 1 there are arranged, one after the other in direction U1 and lying horizontally on the belt, anempty transport pallet 25 a, atransport pallet 25 b loaded with afiber sliver package 5 c, and atransport pallet 25 c fully loaded with fourfiber sliver packages end face 25 2 of eachtransport pallet wall wall 26, thefiber sliver packages transport pallets fiber sliver package 5 has been unloaded onto thetransport pallet 25 b, theupper belt portion 29 1 moves in direction U1 by the width b (seeFIG. 3 c) of afiber sliver package 5. During or after the loading of thetransport pallet 25 b, the alreadyfull transport pallet 25 c can be transported away. Once thetransport pallet 25 b has been loaded with fourfiber sliver packages 5, theupper belt portion 29, is moved in direction U1 so that thefull transport pallet 25 b moves into the position for being transported away and theempty transport pallet 25 a moves into the (middle) position for discharge of the fiber sliver packages 5. A fresh empty transport pallet (not shown) is then placed on theupper belt portion 29 1. - In accordance with
FIG. 10 a, driven by themotor 6, in the course of being discharged from the sliver-depositingarea 10, asupport plate 4, together with a can-lessfiber sliver package 5 d, is moved horizontally in direction I and arrives at a position spaced apart by distance h above thetop face 25 1 of the transport pallet 25 (seeFIG. 10 ′) and in parallel next to afiber 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 (seeFIG. 10 c) of thefiber sliver package 5 d (by a drive device not shown) and spaced apart by distance i above thetop face 4 1 of the support plate 4 (seeFIG. 10 ′). Then, driven by themotor 6, thesupport plate 4 is moved back alone, without thefiber sliver package 5 d, horizontally in direction J beneath the holding-back element 27 (seeFIG. 10 d). In the course of that movement in direction J, thefiber sliver package 5 d, held in place by the holding-back element 27, slides off thesmooth surface 4 1 of thesupport plate 4, so that thefiber sliver package 5 d is removed from thesupport plate 4. At the same time, as shown inFIG. 10 d, thefiber sliver package 5 d is deposited on thesurface 25 1 of thetransport pallet 25. The distance h between thelower face 4 2 of thesupport plate 4 and theupper side 25 1 of the transport pallet 25 (seeFIG. 10 ′) is small, so that when sliding off thesupport plate 4 thefiber sliver package 5 d is lowered onto thetransport 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, thesupport plate 4 can be rotated (not shown) about its longitudinal axis through an angle of about from 5° to 10°, so that thefiber sliver package 5 d is inclined in the direction towards and parallel to the side face of the deposited, inclinedfiber sliver package 5 c. The rotation of thesupport plate 4 assists the downward sliding movement of thefiber sliver package 5 d from thetop 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 thefiber sliver package 5 d to incline in the direction towards and parallel to the side face of thefiber sliver package 5. - According to
FIG. 11 , four can-lessfiber sliver packages 5 a to 5 d are arranged one next to the other on thetop face 25 1 of atransport pallet 25. The sliver end or the end of the last ring of fiber sliver of a top layer (top face 5 5) is joined to the sliver end or the end of the first ring of fiber sliver of a base layer (base surface 5 6) of adjacent fiber sliver packages. In the example shown inFIG. 11 , the sliver end of the last ring of fiber sliver of the top layer (top face 55) offiber sliver package 5 a is joined to the sliver end of the first ring of fiber sliver of the base layer (base surface 5 6) offiber sliver package 5 b. The same applies to the sliver ends and the joining together thereof in respect of the furtherfiber sliver packages fiber 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 fiber sliver packages of the total fiber sliver package, beginning with the top layer (top face 5 5) offiber 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 thetransport pallet 25 withfiber sliver packages 5 a to 5 d arranged on itstop face 25 1. Transverse to the direction of the longitudinal axis of thefiber sliver packages 5 a to 5 d (e.g., parallel to the short end faces of thefiber sliver packages 5 a to 5 d), thetransport pallet 25 can be inclined at an angle γ to the horizontal. The correspondinglyinclined forks 32 of the fork-lift truck 31 can engage under thetransport pallet 25 transverse to the longitudinal axes of thefiber sliver packages 5 a to 5 d. The side faces of thefiber sliver packages 5 a to 5 d and the supportingwall 26 can be inclined at an angle relative to the vertical. Thebundle 5′ comprisingfiber 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 supportingwall 26, and its being supported above the center of gravity of thebundle 5′ or its having a low center of gravity below the supporting means. - The exemplary configuration of
FIG. 13 can use the fork-lift truck 31 ofFIG. 12 , or a similar transport vehicle.Transport pallet 25 supportsfiber 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 thefiber sliver packages 5 a to 5 d. Theforks fiber sliver packages 5 a to 5 d in the direction of their longitudinal axes. Theforks - Referring to
FIG. 14 , sixdraw frames 1 a to 1 f, 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 eachdraw frame 1 a to 1 f. Eachlattice 35 can have sixround cans 36.Reference numbers draw frame 1 a only. Each set of sixround cans 36 can supply six fiber slivers to be drafted to the drafting system 2 (seeFIG. 1 a) of arespective draw frame 1 a to 1 f. At the outlet of eachdraw frame 1 a to 1 f, can-lessfiber 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 eachdraw frame 1 a to 1 f there can be arespective storage device 30 a to 30 f, to which, from one side, the can-lessfiber sliver packages 5 produced in thedraw frame 1 a to 1 f are discharged and in which the can-lessfiber sliver packages 5 are stored ontransport pallets 25. On the respective other side and along thestorage devices 30 a to 30 f there can be arranged arail guide 37 on which (in accordance with the example shown inFIG. 14 ) two driventransport vehicles 38 a, 38 b are moved back and forth in the direction of arrows W1, W2. Thestorage devices 30 a to 30 f can be positioned so that they lie in a common path with thetransport vehicles 38 a, 38 b. At an end region of the rail guide 37 (for example, in the region to the right of thestorage device 30 f inFIG. 14 ) there can be arranged, transversely with respect to therail guide 37, a conveyor device 39 (e.g., a roller conveyor, conveyor belt or the like) fortransport pallets 25 loaded with fiber sliver packages 5 (full pallets). There can also be a second conveyor device 40 (e.g., a roller belt, conveyor belt or the like) forempty transport pallets 25. Theconveyor device 39 leads to apress 41 having abinding device 42, downstream of which there can be arranged scales 43 and alabelling device 44. After that there can be provided afurther conveyor device 45 for forwarding and transporting the boundfiber sliver packages 5, which can consist of abundle 5′ of a plurality of individual fiber sliver packages. - In the exemplary embodiment shown in
FIG. 14 , the transport vehicle 38 a carries twotransport pallets bundle 5′, 5″ of four can-lessfiber sliver packages 5, thetransport pallets storage device 30 a and loaded onto the transport vehicle 38 a. Accordingly, in thestorage device 30 a there are two empty storage positions for twoempty transport pallets 25′. In each of thestorage devices 30 b to 30 e there are twoempty transport pallets 25′ for receiving can-lessfiber sliver packages 5 orbundles 5′. In thestorage device 30 f, two empty storage positions for twoempty transport pallets 25′ are shown. On thetransport vehicle 38 b there can be arranged twoempty pallets 25′, 25″. In operation, the transport vehicle 38 a can travel to one end of theconveyor device 39, wherepallets bundles 5′, 5″ , are loaded one after the other and forwarded to thepress 41 in the direction of arrow X. At thepress 41, thebundles 5′, 5″ can be provided with base and cover boards (not shown), for example of corrugated cardboard, fiberboard or the like, pressed, bound, removed from thetransport pallets 25, and discharged onto theconveyor device 45 in the form of bound bundles. Theempty transport pallets 25′ separated from thebundles 5′, 5″ can be conveyed by means of a cross-conveyor 46 to theconveyor device 40 from where they are loaded in direction Y onto one of thetransport vehicles 38 a or 38 b. - In accordance with the exemplary embodiment of
FIG. 15 , at the inlet of adraw frame 1, for example a Trützschler TD 03, there can be arranged a feed table 35 (lattice) which can be associated with twotransport pallets transport pallet 25 a, and four independent can-less fiber sliver packages 5.5 to 5.8 are stably arranged one next to the other on thetransport pallet 25 b. The fiber sliver packages 5.1 to 5.8 can be worked off individually. For example, in the case of four fiber sliver packages 5.1 to 5.4 and 5.5. to 5.8 ontransport pallets draw frame 1 can be supplied with eight fiber slivers (cf. the fiber slivers 82 inFIG. 20 ). Such an arrangement can create a space-optimized version. - In accordance with
FIG. 16 , upstream of the inlet of thedraw frame 1, for example a Trützschler TD 03, there can be arranged the feed table 35 (lattice) which can be associated with eighttransport pallets 25 a to 25 h. On eachtransport pallet 25 a to 25 h there can be stably arranged one next to the other four can-less fiber sliver packages, for example fiber sliver packages 5.1 ontransport pallet 25 a. In accordance with the exemplary embodiment shown inFIG. 11 , the packages 5.1 are joined to one another by their sliver ends. In that way, the fiber sliver packages on a transport pallet, for example fiber sliver packages 5.1 ontransport pallet 25 a, are unwound one after the other without interruption, bringing the advantage of long sliver run lengths. Where there are four fiber sliver packages on each transport pallet, the run time for a total fiber 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 withround cans 36, eachlattice 35 may be supplied with can-lessfiber 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 fiber sliver packages having elongate cross-sections. Such a fiber 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 acontrol center 50 which determines the appropriate time for exchange of the supports, for example,transport pallets 25, under the spinning positions of the rotor-spinningmachines 51 a to 51 d. For example, thecontrol center 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 optimize the process of exchanging thesupports 25, thecontrol center 50 can draw on the knowledge of information relating to the pure spinning time of the individual spinning positions since the last exchange of thesupports 25 of the spinning position in question. - As the loading station for the
supports 25, the spinning mill can have at least oneflat card 52 a to 52 c, for example a Trützschler TC 03. Each flat card can contain anintegrated drafting system 53 a to 53 c, for example a Trützschler IDF, and arotary plate 54 a to 54 c. Eachflat card 52 a to 52 c can be associated with astorage device storage devices FIG. 9 . Between the rotor-spinningmachines 51 a to 51 d and thestorage devices 55 a to 55 c there can be installed in the plane of the floor of the spinning mill aninduction loop 56. The signals from thecontrol center 50 and the reactions of the sensors from and/or to at least one automatically controlledtransport carriage 57 can be transmitted by the induction loop. Thetransport carriage 57 can have at least onetransport pallet 25 for each of the can-less fiber sliver packages 5.Reference numeral 58 denotes an intermediate storage means (buffer) for transport pallets having can-less fiber sliver packages and for empty transport pallets. The rotor-spinningmachines 51 a to 51 d are sliver-fed spinning machines. -
FIG. 18 shows theflat card 52, for example, a Trützschler flat card TC 03, as a sliver-delivering spinning room machine, having afeed roller 60, feed table 61, lickers-in 62 a, 62 b, 62 c,cylinder 63,doffer 64,stripper roller 65, niprollers web guide element 68,web funnel 69,delivery rollers card top 59. Downstream of the outlet of theflat card 52, there can be arranged a sliver-depositingdevice 72, in which the rotatingrotary plate 54 is located in arotary plate panel 73, above which there is arranged thedrafting system 53, for example, a Trützschler IDF. Thefiber sliver 74 produced by theflat card 52 can pass by way of a sliver funnel through thedrafting system 53, through a sliver funnel with delivery rollers, then through the sliver channel of therotary plate 54, and is ultimately deposited in the form of a can-lessfiber sliver package 5 on asupport plate 4. Thesupport 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. Thefiber sliver package 5 can be stably positioned in a manner corresponding to that shown previously, for example, inFIGS. 1 a, 1 b, and 4. -
FIG. 19 shows a flyer 75 (a sliver-fed spinning room machine) having a spindle andspool device 76, aflyer drafting system 77, and an upstream feed table 35 (lattice). Beneath thelattice 35 there are four can-lessfiber sliver packages 5 a to 5 d, thefiber sliver packages transport pallet 25 a and thefiber sliver packages 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 sixtransport pallets 25 1 to 25 6 carrying stably positioned can-lessfiber sliver packages 5 1 to 5 6 (only 5 1 shown) being arranged beneath the feed table 35 a, and sixtransport pallets 25 7 to 25 12 carrying stably positioned can-lessfiber 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 aguide pulley 81 above each of thefiber sliver packages 5 1 to 5 12. The fiber slivers 82 withdrawn from thefiber sliver packages 5 1 to 5 12, after being guided by the guide pulleys 81, can pass into twodrafting systems preparation machine 80. The draftingsystems drafting system 83 a, the fiber sliver web that has been formed is guided over the web table 84 and, at the outlet of thedrafting system 83 b, laid one on top of the other with the fiber sliver web produced therein. The two fiber sliver webs are drawn into adownstream drafting system 83 c, and the fiber material produced in thedrafting system 83 c is deposited, using a downstreamrotary plate 84, in rings on a substantiallyrectangular support plate 4 which is movable back and forth in the longitudinal direction to form a can-lessfiber sliver package 5. Thefiber sliver package 5 can be stably positioned in a manner corresponding to that shown previously, for example, inFIGS. 1 a, 1 b and 4. The can-lessfiber sliver package 5 can then be supplied to a combing machine (seeFIG. 21 ). - Referring to
FIG. 21 , a combingmachine 90 has six combingheads 91 a to 91 f arranged in a row one next to the other. Each combinghead 91 a to 91 f can be associated with atransport pallet 25 1 to 25 6, there being two of the can-lessfiber sliver packages 5 1 to 5 12 (only 5 1 illustrated) stably positioned on eachtransport pallet 25 1 to 25 6. The fiber slivers that have been deposited in rings are withdrawn from thefiber sliver packages 5 1 to 5 12 which, when seen in plan view, are substantially rectangular. For that purpose, above thefiber sliver packages 5 1 to 5 12 there is alattice framework 93 with guide pulleys (seeFIG. 20 ). The fiber slivers 92 are combed in the combingheads 91 a to 91 f and supplied by way of the sliver table 94 to adrafting system 95, in which the fiber slivers 92 are combined to form asingle fiber sliver 96. In the downstream sliver deposition step, arotary plate 97 deposits thefiber sliver 96 in ring form in the form of a can-lessfiber sliver package 5 on a substantiallyrectangular support plate 4 which is movable back and forth in the longitudinal direction. Thefiber sliver package 5 can be stably positioned in a manner corresponding to that shown previously, for example, inFIGS. 1 a, 1 b, and 4. The can-less fiber sliver package can then be supplied to a spinning machine or a storage means. - The afore-mentioned components, as well as the
fiber 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). Thefiber 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 fiber slivers for the production of fiber structures (roving, wound lap, fiber sliver, yarn). For the explanation inFIG. 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 thefiber sliver packages 5 is sufficient for that purpose. Thefiber sliver packages 5 produced in thedraw 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 inFIG. 14 and 17, a plurality of transport vehicles can be provided, each of which is able to receive a group of can-lessfiber 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 inFIGS. 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 fiber 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 fiber sliver. In contrast, the invention relates to can-less
fiber sliver packages 5, that is to say there are no cans, containers or the like for the fiber sliver. The fiber sliver is deposited, withdrawn, forwarded, stored and supplied in the form of a can-lessfiber 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.
