Description

[0001] Title: Arrangement comprising a spinning preparation machine and a creel device, as well as a set of such an arrangement and a self-propelled fiber belt can

[0002] Description

[0003] The invention relates to an arrangement in the spinning preparation process comprising: a spinning preparation machine and a creel device for feeding the spinning preparation machine with fiber ribbons from a plurality of fiber ribbon cans that can be provided in an installation area of ​​the creel device, as well as a set of such an arrangement and a self-propelled fiber ribbon can.

[0004] From EP 3 165 636 A1, an arrangement with such a gate device for a double-head line is known. The gate device has, for each drawing device of the double-head line, a longitudinal beam that can be positioned above the installation area and which has several take-off devices arranged one behind the other.

[0005] In cases where the system is supplied with fiber slivers from various sources, such as different carding or pre-drawing stations, the properties of the supplied slivers vary depending on the source. This is particularly true when processing cotton fibers. To ensure consistent quality of the fiber slivers doubled and drawn by the drawing devices, each individual feed point is supplied with fiber slivers from a consistent source to maintain a uniform mix. This results in a significant workload for handling the fiber sliver cans at the creel unit.

[0006] The invention is based on the objective of providing an arrangement comprising a spinning preparation machine and a creel device for feeding the spinning preparation machine with fiber slivers from a plurality of fiber sliver cans that can be provided within a single installation area of ​​the creel device. This arrangement enables simplified feeding and unloading of the fiber sliver cans and requires little space. Furthermore, a set consisting of such an arrangement and a self-propelled fiber sliver can is to be provided.

[0007] To solve the problem, an arrangement in the spinning preparation process is proposed, comprising: a spinning preparation machine with a first drawing device; a creel device for feeding the first drawing device with fiber slivers from a plurality of fiber sliver cans that can be provided in a setup area of ​​the creel device; wherein the creel device has a longitudinal beam that can be positioned with respect to a vertical axis above the setup area, which extends in a longitudinal direction and which has several take-off devices arranged one behind the other with respect to the longitudinal direction, wherein the take-off devices are each configured to take one of the fiber slivers from one of the fiber sliver cans; and a track network that has an entry track on which the fiber sliver cans can be moved into the setup area and an exit track on which the fiber sliver cans can be moved out of the setup area.

[0008] A track network within the meaning of the invention corresponds to the predetermined movement paths along which the self-propelled fiber tape cans can move. The track network can include a device by which the movement path of the fiber tape cans can be predetermined or defined. A track of the track network thus defines a movement path of the fiber tape cans. For example, an entry track of the track network defines the movement path of the fiber tape cans when they are moved into the setup area, and an exit track of the track network defines the movement path when the fiber tape cans are moved out of the setup area.

[0009] The inventive design of a track network allows the fiber tape cans to be guided into and out of the installation area. This prevents collisions between empty and subsequent cans and reduces the space required for the movement of the fiber tape cans, thus minimizing the overall footprint of the arrangement.

[0010] In one possible embodiment, the spinning preparation machine can be designed as a line with the first drawing device or as a double-head line with the first drawing device and a second drawing device.

[0011] In the case of a double-headed drawing unit, the first and second drawing units can be connected to each other via an intermediate element. The gate assembly can be designed to feed the first and second drawing units with fiber tapes from the multitude of fiber tape cans that can be provided in the setup area of ​​the gate assembly. The gate assembly has, for each drawing unit, a longitudinal beam that can be positioned above the setup area with respect to a vertical axis and extends in a longitudinal direction, comprising several discharge devices arranged one behind the other with respect to the longitudinal direction. The track network can have a discharge track for each drawing unit, along which the fiber tape cans can be moved out of the setup area.This design of the track network makes it easier to move the fiber tape cans out of the installation area of ​​the arrangement without the fiber tape cans assigned to the first stretching device and the fiber tape cans assigned to the second stretching device interfering with each other.

[0012] In one possible embodiment, the entry lane can be arranged parallel to the longitudinal direction, overlapping the intermediate element. Alternatively, or in combination, the entry lane can run between the two longitudinal beams. In this context, it is also conceivable that one of the longitudinal beams is arranged between the entry lane and one of the exit lanes. In other words, the first longitudinal beam associated with the first stretcher can be arranged between the entry lane and the first exit lane, and the second longitudinal beam associated with the second stretcher can be arranged between the entry lane and the second exit lane. These technical solutions allow for a space-saving design of the arrangement.

[0013] In another possible embodiment, the track network can have a discharge lane for each stretching device, along which the fiber tape cans can be moved out of the setup area. The discharge lanes can be provided as an alternative to the exit lanes or in combination with them. One of the exit lanes can be arranged between the entry lane and one of the discharge lanes. This arrangement makes the removal of the emptied fiber tape cans more flexible.

[0014] In another possible embodiment, the track network can include a cross track for each gate release device, running transversely to the longitudinal direction and connecting the entry lane with one of the exit lanes. In particular, several cross tracks can be provided, arranged such that the entry lane is connected to both exit lanes.

[0015] In another possible embodiment, the route network can be described by reference points. These reference points can be marked, for example, by RFID tags. The reference points can therefore also be referred to as reference point markers. The reference points can be interconnected via a guide track. The guide track can be formed, at least in sections, by one or more magnetic strips.

[0016] In one possible embodiment, each discharge device of the gate assembly can have a reference point serving as a distribution point at the interface between the entry track and one of the cross tracks. In the case of a double-headed track, one discharge device per longitudinal beam can share a common distribution point. Specifically, these two discharge devices can be arranged in a transverse plane that is orthogonal to the longitudinal direction.

[0017] Each dispensing device can have a dispensing position where the fiber tape canister can be positioned to dispense the corresponding fiber tape. A dispensing reference point can be provided at each dispensing position. Each dispensing device can also have an intermediate storage position where the fiber tape canister can be positioned for transferring it to the dispensing position. An intermediate storage reference point can be provided at each intermediate storage position. For each dispensing device, the dispensing reference point and the intermediate storage reference point can be located on the corresponding cross track or on a common cross track. The dispensing reference points associated with one of the longitudinal beams can be located on the exit track associated with that longitudinal beam.

[0018] To solve the problem, a set is further proposed, comprising: an arrangement according to a previously described embodiment, and at least one self-propelled fiber tape can, wherein the self-propelled fiber tape can is guided on the track network by a guiding device of the arrangement. The set can also be referred to as an arrangement.

[0019] In one possible embodiment of the set, the self-propelled fiber belt container can have a width. The width can correspond to the diameter of a cylindrical envelope whose cylinder axis runs vertically when the fiber belt container is on a flat surface. For round containers, the width can correspond to the diameter of the round container. A distance between the entry track and the exit track can be greater than or equal to twice the width of the self-propelled fiber belt container and can, in particular, be less than three times the width of the self-propelled fiber belt container.

[0020] The following section explains, with reference to the figures, a possible embodiment of the arrangement according to the invention with a double-head section and an associated gate. This shows:

[0032] Figure 11 shows a longitudinal view of the arrangement from Figure 1 at a gate position with an active can at the extraction position and a free intermediate storage position.

[0033] Figures 1 to 11, which are described together below, show an arrangement 1 according to the invention with a creel device 2. The creel device 2, as is known per se, serves to feed a downstream spinning preparation machine 3, here a double-head drawing unit or a double-head drawing unit, with a plurality of fiber slivers 5 that can be provided in movable fiber sliver cans 4. The fiber sliver cans 4 are shown as round cans by way of example.

[0034] On a stationary floor 6, in particular the floor of a spinning mill, on which the arrangement 1 is installed, a setup area 8 is defined at or below the creel device 2, in which the fiber sliver cans 4 or the fiber slivers 5 are provided. The setup area 8 can be formed by a section of the floor 6 and can therefore also be referred to as the setup area. The spinning preparation machine 3, as is known per se, serves to homogenize the fiber slivers 5 provided by the upstream creel device 2. A control unit 13 is provided, which is configured to control the spinning preparation machine 3 and the creel device 2 together, and which can be installed in the spinning preparation machine 3.

[0035] To clarify the orientation of arrangement 1 in space, a longitudinal axis X, a transverse axis Y, and a vertical axis Z are specified, defined in terms of a fixed Cartesian coordinate system and indicated by corresponding arrows. The vertical axis Z is perpendicular to the ground 6. Terms such as "below," "below," "above," or "below" represent spatial references to arrangement 1.

[0036] Arrangement 1 is specifically designed for the use of self-propelled vehicles 14 in spinning mills. The fiber tape cans 4 can be moved autonomously by means of the self-propelled vehicles 14. The arrangement of fiber tape cans 4 and self-propelled vehicle 14 can be referred to as a self-propelled fiber tape can. The self-propelled fiber tape cans can each have a width B_4. The vehicles 14 can be permanently connected to the fiber tape can 4, as shown here, so that the unit consisting of vehicle 14 and fiber tape can 4 can be referred to as a "self-propelled spinning can". Such a self-propelled spinning can is shown in European patent application EP 4276228 A1 filed by the applicant. Instead of a fixed or permanent connection, it can also be provided that the vehicle 14 can, for example, pick up and put down the fiber tape can 4 or attach and move it laterally.In principle, arrangement 1 is also suitable for use in spinning mills where the fiber tape cans 4 are moved manually by the operator.

[0037] The spinning preparation machine 3, as a double-head unit, comprises a first drawing device 70 and a second drawing device 70', arranged side by side, each with a drawing unit for drawing pre-loaded fiber strips 5. The first drawing device 70 and the second drawing device 70' each extend longitudinally in a direction parallel to the longitudinal axis X. The two drawing devices 70, 70' are connected to each other via an intermediate element. In this case, the intermediate element is designed as a platform 71, from which an operator has access to both drawing devices 70, 70' and their respective drawing units. The platform 71 also extends longitudinally in a direction parallel to the longitudinal axis X and has a width B_71.

[0038] The gate assembly 2 comprises, for each stretching device 70, 70', a longitudinal beam 7, 7' arranged above the installation area 8 with respect to the vertical axis Z. The longitudinal beams 7, 7' are each supported on the ground 6 by a support device with supports 90. In this case, three supports 90 are provided. The position of the supports 90 is shown in Figure 3 and applies analogously to the embodiments shown in Figures 4 and 5. For the sake of clarity, an explicit representation of the position of the supports 90 in Figures 4 and 5 is omitted. The longitudinal beams 7, 7' each extend in a longitudinal direction that is aligned parallel to the longitudinal axis X. The longitudinal beams 7, 7' are thus aligned parallel to each other and have a distance D_7 between them. The longitudinal beams 7, 7' are designed in a mirror-symmetrical manner with respect to a vertical plane which contains the entrance track E of the route network 18 described below.The statements regarding the first stretching device 70 and the longitudinal beam 7 therefore apply analogously to the second stretching device 70' and the associated longitudinal beam 7'. For the sake of clarity, Figure 2 therefore only shows the side of the double-headed stretcher with the first stretching device 70 and the associated longitudinal beam 7. It will be understood by those skilled in the art that this view in Figure 2 corresponds to an arrangement according to the invention with a single stretcher. In the subsequent figures, the reference numerals that refer to half of the arrangement with the second stretcher 70' and the second longitudinal beam 7' are additionally marked with a superscript.

[0039] The gate assembly 2 has, for each drawing device 70, 70' and each longitudinal beam 7, 7', by way of example, six gate positions 38 for a 6-fold doubling, which are designated in Figure 2 by reference numerals 38.1, 38.2, 38.3, 38.4, 38.5, 38.6. For this purpose, several, here six, draw-off devices 9 are arranged one behind the other on each of the longitudinal beams 7, 7' in the direction of the longitudinal axis X, in order to be able to simultaneously draw off and feed the fiber slings 5 ​​from up to six of the fiber sling cans 4 for each drawing device 70, 70'.

[0040] To ensure continuous operation of the arrangement 1, it is necessary that at least one fiber tape can 4 filled with fiber tape 5 is always available at the respective gate position 38. The fiber tape cans 4 from which the fiber tape 5 is currently being drawn are referred to as active cans, regardless of which of the can positions 16, 17 they are currently located in. The active cans 4 are designated by reference numeral 4.1 in the figures. The subsequent fiber tape cans filled with fiber tape 5, which provide replenishment at the gate assembly 2, are referred to as follower cans and are designated by reference numeral 4.2 in the figures. Empty fiber tape cans 4, from which the fiber tape 5 has already been drawn at the gate assembly 2, are designated as empty cans and are designated by reference numeral 4.3. In Figure 1, the active cans 4.1 are also shown with half hatching, and the follower can 4.2 is shown with full hatching.The hatching pattern describes the properties of the fiber tape 5 contained in the respective fiber tape cans 4. Identical hatching patterns thus correspond to identical properties of the contained fiber tape 5. For example, fiber tapes supplied from a specific upstream processing station will have the same hatching pattern. The fiber tape cans 4 can be marked with an identical hatching pattern if they are supplied by a specific upstream carding or drawing unit. It is therefore evident that the arrangement according to the invention advantageously enables a uniform mixture of fiber tapes 5 in order to keep the properties of the drawn fiber tape as constant as possible.

[0041] Each take-up device 9 is provided with a deflecting element 10 for deflecting the fiber strip 5 coming from the respective fiber strip can 4 towards one of the longitudinal ends 15 of the longitudinal beam 7, 7' facing the spinning preparation machine 3. The deflecting elements 10 can be feed rollers coupled to the drive train of a motor 11 and thus rotatably driven. The deflecting elements 10 extend orthogonally to the longitudinal axis of the respective longitudinal beam 7, 7' and are arranged on the longitudinal side of the respective longitudinal beam 7, 7' that faces away from the entry track E described below. In other words, the deflecting elements 10 are arranged on the longitudinal side of the respective longitudinal beam 7, 7' that faces away from the other longitudinal beam. In principle, it is also conceivable that the deflection elements 10 are arranged on the longitudinal side of the respective longitudinal beam 7, 7' that faces the other longitudinal beam.The longitudinal beams 7, 7' can therefore be described as single-row gate beams.

[0042] The driven deflecting element 10 can be associated with a traveling upper roller 12, with which the respective deflecting element 10 forms a roller pair between which the respective fiber strip 5 can be guided. On the side of the respective take-off device 9 facing away from the spinning preparation machine 3, a guide ring 23 can be arranged, through which the respective fiber strip 5 is guided during take-off.

[0043] At one end of each of the two longitudinal beams 7, 7', remote from the respective stretching device 70, 70', a motor 11, which is connected to the drive devices 9 and is preferably an electric motor, is attached to the longitudinal beam 7, 7'. For this purpose, a drive train can be accommodated in the longitudinal beam 7, 7', which is coupled to the respective drive devices 9. The control unit 13 can be configured to control the two motors 11.

[0044] Furthermore, the gate device 2 can include at least one display device 24, wherein the control unit 13 is configured to display information on the at least one display device 24, for example, to indicate whether manual intervention by the operator on the gate device 2 is necessary. In a further embodiment, a separate display device 24 can be arranged adjacent to each trigger device 9. The respective display device 24 can, for example, be arranged on top of the longitudinal beam 7 so that the display information is clearly visible from a distance. The display devices 24 are designed here, in particular, as rod-shaped signal lights. The display information can be represented, for example, by different colors.

[0045] Each take-up device 9 has several, here two, associated can positions permanently assigned within the setup area 8. A first can position can be designated as take-up position 16 and a second can position as intermediate storage position 17. The can positions are illustrated with dashed circles in Figures 2 to 5. The intermediate storage position 17 can be located below the longitudinal beam 7, 7' of the associated take-up device 9. The take-up position 16 is located on the side of the associated intermediate storage position 17 that faces away from the entry lane E described below. Each can position 16, 17 is integrated into a track network 18 of the spinning mill, in which the driverless, self-propelled fiber tape cans 4, 14 can move under the control of a higher-level guidance system 33. The connection between the guidance system 33 and the vehicles 14 is preferably a radio link.The control unit 13 can communicate with the control unit 33 via a radio link and / or a wired connection. The control unit 33 can also be referred to as the central control computer.

[0046] The track network 18 can include a guide track 19 arranged on the ground 6, which is defined by reference points 20 between which magnetic strips are arranged. The magnetic strips do not necessarily have to extend from one reference point to the other, but can also cover a partial area between two reference points. For the sake of clarity, similar reference points are usually only marked once with a corresponding reference symbol in the figures. To characterize special reference points, the reference symbol 20 is also given a suffix.

[0047] The reference points 20 can, for example, be marked by RFID tags. Accordingly, the terms reference point and reference point marking are used synonymously here. Radio Frequency Identification (RFID) technology allows the contactless transmission of data stored on the RFID tags or transponders. Alternatively, the markers can be a barcode or a two-dimensional code – also known as a QR code (quick response code). The respective RFID tag contains, for example, a unique identifier for the respective reference point 20. Using a reading device attached to the vehicle 14, the address information can be read and transmitted to the higher-level control unit 33. This unit can then transmit commands to the vehicle 14, which the vehicle 14 is to execute at the respective reference point 20. Furthermore, the vehicle 14 can follow the guide track 19 using the reading device.For example, the reading device includes a track reading device, here for following the magnetic tapes, and a point reading device, here in the form of an RFID reading unit for reading the RFID tags. At each waypoint in the route network 18, where the vehicle 14 may be able to execute a command, such a reference point 20 can be provided, which may in particular be equipped with its own RFID tag.

[0048] In particular, the combined view of Figures 1 and 3 to 5 reveals the track network 18 and the associated guide track 19, on which the cans 4 can move within the area of ​​the arrangement 1. The intended directions of travel for the self-propelled fiber tape cans 4 are indicated by arrows in the figures. The track network 18 is defined by a grid of reference points 20, which are connected via the guide track 19. A reference point 20.16, 20.16' is located on the floor 6 at each take-up position 16, 16', and a reference point 20.17, 20.17' is located at each intermediate storage position 17, 17'. If the reading device of vehicle 14 reads one of the reference points 20.16, 20.16' or 20.17, 20.17', vehicle 14 sends the corresponding identifier to the control device 33 and thus informs it that the vehicle is at a defined extraction position 16, 16' or intermediate storage position 17, 17'.The guidance device 33 in turn sends the corresponding information to the control unit 13 of the arrangement 11 and forwards movement commands to the self-propelled fiber belt cans 4, 14.

[0049] The reference points 20.16, 20.16' of the take-off positions 16, 16' are arranged on a departure track A, A', each extending parallel to the longitudinal axis X. The departure track A, A' is connected to a transition section 80 of the track network 18, which connects the setup area 8 with other areas of the track network 18, for example, with the belt unloading device of an upstream spinning preparation machine. The departure track A, A' thus serves both for positioning active cans 4.1, 4.1' on one of the take-off positions 16, 16' and simultaneously as a departure track for empty cans 4.3 from the setup area 8.

[0050] Each extraction position 16, 16' is assigned a distribution point 20. E. In this case, the opposing extraction positions 16, 16' of the two longitudinal beams 7, 7' share a common distribution point 20. E. The distribution points 20. E are located on an entry track E, which extends parallel to the longitudinal axis X. The entry track E is connected to the transition section 80 of the track network 18. The entry track E thus serves as an entry point for subsequent cans 4.2, 4.2' into the setup area 8.

[0051] Each extraction position 16, 16' is connected to its corresponding distribution point 20, E via a cross-track Q, Q' of the track network 18. The cross-track Q, Q' runs transversely, essentially orthogonally, to the longitudinal beams 7, 7'. The cross-track Q, Q' also runs transversely, essentially orthogonally, to the entry track E and its corresponding exit track A, A', respectively. A reference point 20, 17, 20, 17' of an intermediate storage position 17, 17', which is assigned to the corresponding extraction position 16, 16', is arranged on each cross-track Q, Q'. The reference points 20, 17, 20, 17' are aligned with each longitudinal beam 7, 7' in the direction of the longitudinal axis X.

[0052] At least two cross paths Q, Q', which are assigned to a common track alignment 70, 70', have a distance D_QQ that is greater than or equal to the sum of the width B_4 of the self-propelled fiber belt can 4, 14 and the longitudinal extent X of the support 90. This ensures that the self-propelled fiber belt can 4, 14 can be guided past the support 90 via the cross path without collision. The smallest possible distance D_QQ is desirable, depending on the positioning accuracy of the self-propelled fiber belt can 4, 14 on the guide track 19, which is enabled by the control system 33.

[0053] The entry lane E is spaced at a distance D_EA from the exit lanes A and A' that is greater than or equal to twice the width B_4 of the arrangement consisting of the transport container 4 and the vehicle, i.e., the self-propelled fiber belt container 4, 14. This distance can be, in particular, 2.05 times, 2.1 times, 2.2 times, 2.5 times, or 3 times the width B_4 of the self-propelled fiber belt container. Advantageously, the entry lane E is spaced at the same distance D_EA from the exit lanes A and A'. The smallest possible distance D_EA is desirable, depending on the positioning accuracy of the self-propelled fiber belt container 4, 14 on the guide track 19, which is enabled by the control system 33.

[0054] The distance D_AA between the departure lanes A, A' is greater than or equal to four times the width B_4 of the self-propelled fiber belt container 4, 14. In particular, the distance between the departure lanes A, A' can be 4.05 times, 4.1 times, 4.2 times, 4.5 times, or 5 times the width B_4 of the self-propelled fiber belt container. These configurations ensure that the self-propelled fiber belt container 4, 14 can move on the entry lane E without collision. The smallest possible distance D_AA is desirable, depending on the positioning accuracy of the self-propelled fiber belt container 4, 14 on the guide lane 19, which is enabled by the control system 33.

[0055] The setup area 8 is the area required to move the self-propelled fiber tape cans 4 in the area of ​​the longitudinal beams 7, 7' to the can positions 16, 16' and 17, 17'. The setup area 8 can extend, for example, in the longitudinal direction X from the spinning preparation machine 3 to an end of the longitudinal beams 7, 7' opposite the spinning preparation machine 3, or to the transition section 80 of the drafting network 18. In the transverse direction Y, the outer boundaries of the setup area 8 can be defined such that a self-propelled fiber tape can 4, 14 is just within the setup area 8 when the self-propelled fiber tape can 4, 14 travels along an outer track of the drafting network 18.

[0056] A self-propelled fiber tape can 4, guided by the control unit 33 to feed one of the stretching devices 70, 70' at a specific take-off position 16, 16', enters the setup area 8 via the entry track E and follows the entry track E until it reaches the distribution point 20, E, which is assigned to the specific take-off position 16, 16'. The fiber tape can 4 then turns onto the corresponding cross track Q, Q' and positions itself at the intermediate storage position 17, 17', which is assigned to the specific take-off position 16, 16'. If the corresponding take-off position 16, 16' is free, the fiber tape can 4 is directed to it by the control unit 33. There, the fiber tape 5 is taken off the fiber tape can 4. The fiber tape can 4, after complete removal, is used as empty can 4.3 together with the empty cans 4.3 of the further gate positions 38 along the departure tracks A, A' from the assembly area 8 are directed onto the transition section 80.

[0057] Figure 4 shows a first alternative of the track network 18 and the associated guide track 19, on which the cans 4 move in the area of ​​arrangement 1. In this case, the discharge positions 16, 16' are arranged on the respective cross track Q, Q' between the entry track E and the associated exit track A, A'. This design has the advantage that the empty cans 4.3, which are arranged on the discharge positions 16, 16, can be guided independently of one another to the transfer section 80. However, a disadvantage is the increased space requirement.

[0058] Figure 5 shows a second alternative of the track network 18 and the associated guide track 19, on which the cans 4 move in the area of ​​arrangement 1. In addition to the configuration of Figure 3, diversion tracks C, C' are arranged parallel to the departure tracks A, A'. The diversion tracks C, C' are connected to the transfer section 80 and, via the cross tracks, to the departure tracks A, A'. The distance D_AC of the respective diversion track C, C' from the adjacent departure track A, A' is greater than or equal to the width B_4 of the self-propelled fiber belt can. This configuration has the advantage that the empty cans 4.3, which are arranged on the departure tracks A, A', can be guided independently of one another to the transfer section 80. However, a disadvantage is the increased space requirement.Therefore, the smallest possible distance D_AC should be aimed for, depending on the positioning accuracy of the self-propelled fiber tape can 4, 14 on the guide track 19 made possible by the control system 33.

[0059] As can be seen particularly in Figure 6, a detection device 25, connected to the control unit 13, is provided below the longitudinal beam 7 of each dispensing device 9 for detecting an object in a detection area 26 of the respective detection device 25. The respective detection device 25 is oriented such that its detection area 26 is located below the associated dispensing device 9 with respect to the vertical axis Z. The control unit 13 is configured to recognize, depending on the signals received by the detection devices 25, whether the respective fiber tape can 4, from which the fiber tape 5 is dispensed at the respective dispensing device 9, is in the dispensing position 16 or the intermediate storage position 17. When the fiber band 5 is pulled off, centrifugal forces act on the fiber band 5, so that the path of the fiber band 5 forms the geometry of a balloon, which is also known as the “pulling balloon” 34.The respective detection device 25 is oriented such that at least a portion of the pull-off balloon 34 formed during the pull-off process is detected by the detection area 26 when the fiber tape 5 is pulled off from the pull-off position 16, 16'. It is sufficient if the fiber tape 5 occasionally crosses the detection area 26.

[0060] Each detection device 25 comprises a transmitter and a receiver. The detection devices 25 are designed as reflective photoelectric sensors. As is known per se, the transmitter emits light or a light beam into the surroundings, here the associated detection area 26. When an object enters the path of the light beam, the light is reflected from the object's surface. The receiver in the reflective photoelectric sensor registers the reflected light. The respective detection device 25 processes the received light signal and converts it into an electrical signal, which is then forwarded to the control unit 13.

[0061] Each detection device 25 is attached to a holding element 42 that extends from the longitudinal beam 7 towards the base 6. The holding elements 42 are spaced apart from the dispensing devices 9 so that the detection devices 25 can view the respective dispensing balloon 34 laterally. Each detection device 25 is oriented such that the respective fiber tape 5 cannot be detected or does not cross the respective detection area 26 when the fiber tape can 4, from which the fiber tape 5 is dispensed, is in the intermediate storage position 17, 17'.

[0062] Figure 6 further shows that each take-up device 9 is equipped with a tape break sensor device 21, arranged on the longitudinal beam 7 and connected to the control unit 13. The tape break sensor device 21 can, for example, comprise an optical sensor 30 directed towards a guide 31, wherein a measuring chamber 22 is defined between the optical sensor 30 and the guide 31, which the sensor 30 monitors. The guide 31 serves to guide the fiber tape 5, taken from the respective take-up device 9, through the measuring chamber 22. For example, the optical sensor 30 can be directed towards a guide 31 designed as a wall, along which the fiber tape 5 is moved. Alternatively, the tape break sensor device 21 can, for example, comprise contact rollers, which, for example, together with the deflecting element 10 designed as a feed roller, form a pair of rollers between which the respective fiber tape 5 can be guided.

[0063] Thus, the control unit 13 can determine for each gate position 38 individually, based on the signals received by the detection devices 25 and the signals received by the tape break sensor devices 21, whether a fiber tape 5 is being pulled off at gate position 38 and whether the fiber tape can 4, from which the fiber tape 5 is currently being pulled off, is at the pull-off position 16, 16' or at the intermediate storage position 17, 17'. The control unit 13 can display the status on the display device 24 assigned to the respective gate position 38, for example, whether manual intervention is necessary.

[0064] Specifically, the control unit 13 can indicate on the display device 24 assigned to the respective gate position 38 whether an unintended tape break has occurred. The signal from the tape break sensor devices 21 is sufficient for this purpose. In this case, the display device 24 can, for example, flash red.

[0065] Furthermore, the control unit 13 can indicate on the display device 24 assigned to the respective gate position 38 that the fiber tape 5 is being pulled from an active canister 4.1 positioned at the take-up position 16 and that one end of the fiber tape 5 of the active canister 4.1 must be connected to one end of the fiber tape of the subsequent canister 4.2, which is positioned at the associated intermediate storage position 17. In this state, the tape break sensor devices 21 send a signal to the control unit 13 indicating that no tape break has occurred, and the detection devices 25 send a signal indicating that the take-up balloon 34 is being moved within the detection area 26. Additionally, the control unit 13 has been informed by the master controller 33 about the positioning of a fiber tape canister 4 at the intermediate storage position 17. In this case, the display device 24 can, for example, flash yellow. This state is shown in Figure 7.

[0066] Furthermore, the control unit 13 can indicate on the display device 24 assigned to the respective gate position 38 that the fiber tape 5 is being pulled from an active can 4.1 positioned at the pull-out position 16 and that no further action is required. In this state, the tape break sensor device 21 sends a signal to the control unit 13 indicating that no tape break has occurred, and the detection device 25 sends a signal indicating that the pull-out balloon 34 is moving within the detection area 26. The display device 24 can, for example, output a continuous green signal in this case. This state is shown in Figures 8 and 11.

[0067] Furthermore, the control unit 13 can indicate on the display device 24 assigned to the respective gate position 38 that the fiber tape 5 is being drawn from an active canister 4.1 positioned at the intermediate storage position 17 and that the active canister 4.1 is being moved from the intermediate storage position 17 to the draw-off position by the control unit 33. To achieve this state, the detection devices 25 send a corresponding signal to the control unit 33 via the control unit 13 when the draw-off balloon 34 swings out of the detection area 26. This change of state is shown by the sequence in Figures 8 and 9. In this case, shown in Figures 9 and 10, the display device 24 can, for example, output a green flashing signal.

[0068] The gate assembly 2 also has at least one acknowledgement button 39, one acknowledgement button 39 for each gate position 38. The operator can press this button, for example, to inform the control unit 13 that a manual intervention has been carried out. The display of the respective indicator device 24 can then change.

[0069] Figures 7 to 11 show a sequence of events at one of the creel positions 38. Initially, the respective fiber sliver can 4 is positioned at creel position 38 as the active can 4.1 at the take-off position 16, as shown in Figure 7. The fiber sliver 5 is thus taken from the active can 4.1. During the take-off of the fiber sliver 5, centrifugal forces act, so that the path of the fiber sliver 5 forms the geometry of the take-off balloon 34, as can be seen in Figure 7. The higher-level control unit 33 coordinates the movements of all fiber sliver cans 4 and will always strive to provide two fiber sliver cans 4 at creel positions 38, i.e., one active can and one follower can, in order to ensure an uninterrupted production process of the spinning preparation machine 3.

[0070] When the control unit 13 is informed by the higher-level control unit 33 that the respective intermediate storage position 17 is occupied by another fiber tape can 4, i.e., the subsequent can, as shown in Figure 7, the control unit 13 controls the respective indicator device 24 to light up or flash yellow. The change to yellow signals to the operator that manual intervention, in this case the piecing process, is necessary. During the pending piecing process, the operator must connect the tape end 40 of the active can 4.1 with the tape beginning 41 of the subsequent can 4.2, as shown in Figure 8. Once the piecing process has been carried out, the operator confirms this by pressing the associated acknowledge button 39. The control unit 13 then controls the respective indicator device 24 to light up green.

[0071] As long as the control unit 13 has not yet received notification that the respective intermediate storage position 17 is occupied by a subsequent can 4.2, the control unit 13 controls the respective display device 24 to also light up in green.

[0072] When the fiber belt 5 of the active canister 4.1, located at the take-off position 16, runs dry, the belt skips and the fiber belt 5 is pulled from the fiber belt canister 4 located at the intermediate storage position 17, 17'. As shown in Figure 9, the take-off balloon 34 moves out of the detection area 26. Subsequently, the empty canister 4.3, located at the take-off position 16, 16', is guided along the departure track A, A' or the diversion track C, C' to the transfer section 80.

[0073] The active canister 4.1, positioned at the intermediate storage position, is subsequently moved to the now-vacant extraction position 16, while the fiber tape 5 is extracted. The extraction balloon 34 then returns to the detection area. Reference numeral
