[0001] The present invention relates to a textile machine in a spinning preparation machine, a

[0002] A self-propelled transport vehicle for a sliver can and a construction unit of such a textile machine and a method for

[0003] Run this method of constructing the unit. Background Art

[0004] In spinning preparation machines, textile fibers are prepared for the spinning process.

[0005] In the process, the fibers are separated, parallelized and formed into fiber strands.

[0006] The fiber sliver coiling device places the fiber sliver into the transport can in a swing coil to

[0007] From one processing station to another. Here, the transport cans are used as

[0008] The empty cans are fed to the sliver coiling device and after filling are removed from the sliver as full cans.

[0009] The coiling unit is transported to the next processing unit. In order to achieve the most time-efficient

[0010] To change from full to empty cans and avoid possible idle time, the empty cans are positioned at the fiber

[0011] The sliver coiler is in the waiting position. This full

[0012] The cans move from the filling position. At the same time, the empty cans move from the waiting position to the filling position.

[0013] In order to move the transport can to the sliver coiling device or from the sliver coiling device to the

[0014] To move to the next processing device, a self-propelled transport vehicle is known.

[0015] DE 10 20 22 11 1 675 A1 discloses a self-propelled transport vehicle for transporting cans.

[0016] The transport vehicle has an electrical energy store and a charging station for charging the energy store.

[0017] Charging port for charging. Summary of the invention

[0018] The object of the present invention is to provide a textile machine which can be used for transporting

[0019] Time-efficient charging of a self-propelled transport vehicle for transporting cans.

[0020] A corresponding construction unit consisting of a self-propelled transport vehicle for transporting cans and such a textile machine, as well as a method for operating the construction unit are provided.

[0021] In order to solve the above-mentioned problem, a textile machine is proposed, comprising: a fiber sliver coiling device for placing fiber sliver coils into transport cans, which is arranged at a filling position; a moving path, on which a self-propelled transport vehicle for transporting the transport cans can be moved from a waiting position to a filling position; and a charging station, which is designed to charge an energy storage device of the self-propelled transport vehicle when the self-propelled transport vehicle is positioned at the waiting position.

[0022] The textile machine according to the invention has the following advantages: a waiting position is assigned to the textile machine and the charging station can charge the energy storage device of the self-propelled transport vehicle while the transport vehicle usually stops unproductively at the waiting position of the textile machine in order to be subsequently filled at the filling position. The textile machine thus makes it possible to convert unproductive waiting time into effective charging time. Thus, a higher time utilization of the transport cans can be achieved, since a separate charging stop at an external charging station and the corresponding travel path there can be omitted.

[0023] In one possible embodiment of the textile machine, a fiber strip processing device for processing the fiber strip is arranged upstream of the fiber strip coiling device in the transport direction of the fiber strip. The fiber strip processing device can be a carding machine, a drawing machine, a combing machine or a lap machine. The fiber strip processing device can deliver the processed fiber strip to the fiber strip coiling device at an adjustable or controllable delivery speed.

[0024] In one possible embodiment, the fiber strip coiling device can include a rotatably driven coiling disk, which is arranged vertically above a can turntable that is also rotatably driven. The transport can can be positioned on the can turntable during the coiling of the fiber strip. Therefore, the filling position is arranged on the can turntable. The coiling disk and the can turntable can be driven in accordance with the conveying speed in such a way that the fiber strip is coiled in the transport can in a cycloidal manner.

[0025] In one possible embodiment, the movement path can be formed at least partially by a base plate of the frame. The frame can carry, for example, a fiber sliver coiling device and / or a drafting mechanism. The movement path can be formed at least partially by a substantially flat surface of the base plate. The movement path can also be formed partially by a ramp.

[0026] In one possible embodiment, the charging station can be connected to the rack. In particular, the charging station can be fastened to the bottom plate of the rack and / or integrated into the bottom plate. It is also conceivable that the charging station is integrated into the housing of the rack. The waiting position can be arranged on the bottom plate of the rack.

[0027] In a possible embodiment, the movement path can be formed at least partially by a placement surface on which the textile machine can be positioned. The placement surface can be the floor of a spinning mill. In this case, the waiting position can be arranged on the placement surface. The shortest distance between the waiting position and the frame can be less than or equal to the clear width of the movement path in the bottom area of ​​the frame.

[0028] In a possible embodiment, the waiting position can be alternatively arranged on the bottom plate or placement surface of the rack, wherein the shortest distance between the waiting position and the rack is less than or equal to the clear width of the moving path in the bottom plate area of ​​the rack. In particular, the shortest distance between the waiting position and the rack can be equal to half of the clear width of the moving path in the bottom plate area of ​​the rack.

[0029] In a possible embodiment, the waiting position and the filling position can both be marked by a position mark. The position mark can be detectable by a sensor device of the self-propelled transport vehicle. The position mark can be designed as an image mark or an RFID transponder, for example.

[0030] In one possible embodiment, the charging station can have electrical charging contacts that can be contacted with a charging interface of the self-propelled transporter. The charging station or the electrical charging contacts can be connected to an electrical grid. The charging contacts can be spring-mounted in the housing of the charging station.

[0031] Alternatively or in combination, the charging contacts can be movably supported in the housing of the charging station. The charging contacts can be supported in the housing in particular in such a way that they can be moved toward and away from the waiting position. It is conceivable that the charging contacts are movably supported in the housing of the charging station in such a way that they can be moved transversely, in particular orthogonally, to the movement path. Thus, when the self-propelled transport vehicle is positioned in the waiting position, the charging contacts can be moved vertically from below toward the charging interface. The charging contacts can include one or more contact pins, which can contact complementary charging contacts of the charging interface. In particular, the contact pins can be inserted into complementary recesses of the charging interface.

[0032] In one possible embodiment, the movement path can include cleaning openings which are arranged around the waiting position and are fluidically connected to the suction device.

[0033] In order to achieve this object, a construction unit is also proposed which consists of a self-propelled transport vehicle for transporting transport cans and a textile machine of the above-described design.

[0034] The self-propelled transporter can have at least one drive wheel and at least one support wheel, by means of which the self-propelled transporter can move onto the base surface. The support wheel can also be referred to as a control wheel. The self-propelled transporter can have a drive unit in the form of an electric motor, which drives the at least one drive wheel. The self-propelled transporter can have an energy storage device, such as a battery. The energy storage device can be electrically connected to the drive unit. The energy storage device can be electrically connected directly to the charging interface or indirectly via an onboard charger.

[0035] In one possible embodiment, the transport can can be mounted on a self-propelled transport vehicle or fastened on the self-propelled transport vehicle. In an alternative embodiment, the self-propelled transport vehicle can be integrated into the end section of the bottom side of the transport can.

[0036] In addition, in order to solve the described task, a method for operating a construction unit in the previously described design is provided, comprising the following steps: a self-propelled transport vehicle moves to a waiting position of a textile machine; while the self-propelled transport vehicle is positioned at the waiting position, an energy storage device of the self-propelled transport vehicle is charged with the aid of a charging station; the self-propelled transport vehicle moves from the waiting position to a filling position; while the self-propelled transport vehicle is positioned at the filling position, a fiber loop is placed into a transport can.

[0037] In a possible embodiment of the method, in order to charge the energy storage device of the self-propelled transport vehicle, the charging contacts of the charging station can be moved until the charging contacts are in contact with the charging interface of the self-propelled transport vehicle. In this case, this movement can be carried out toward the waiting position or in the vertical direction away from the bottom plate of the frame.

[0038] Alternatively or in combination, in order to charge the energy storage device of the self-propelled transport vehicle, the self-propelled transport vehicle can be moved towards the charging station until the charging interface comes into contact with the charging contacts of the charging station.

[0039] In a possible embodiment of the method, the movement of the self-propelled transporter to the waiting position and / or the movement of the self-propelled transporter from the waiting position to the filling position can be controlled by the central control device. The central control device can be designed to control or coordinate the movement of multiple self-propelled transporters. For this reason, when the position mark, such as the mark of the waiting position or the filling position is detected by the sensor device of the self-propelled transporter, the central control device can transmit control instructions to the self-propelled transporter. These control instructions can include the rotation of the self-propelled transporter around its vertical axis, the translation of the self-propelled transporter along the longitudinal axis (forward driving / reverse driving), the combination of rotation and translation or the sequence of rotation and translation. The sequence can also include a waiting time. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Described later together Figures 1 to 5, a textile machine 1 according to the invention is shown in a first embodiment, which is placed on a placement surface 38 of a spinning mill. The textile machine 1 comprises a fiber strip processing device for processing a fiber strip 2 and a fiber strip coiling device 5 for coiling the fiber strip 2 into a transport can 25. The fiber strip processing device generates or processes the fiber strip 2 and conveys the fiber strip to the fiber strip coiling device 5 at an adjustable conveying speed. Figure 1 and Figure 2 For the sake of clarity, only the fiber strip coiling device 5 is shown, and the fiber strip processing device is omitted. The fiber strip processing device can be designed as a carding machine, a drawing machine, a combing machine or a strip lap machine, for example.

[0053] The fiber sliver coiling device 5 comprises rollers 6 which deflect the fiber sliver 2 in a known manner towards a rotatable coiling disk which is arranged vertically above a can carousel 10 which is also driven rotatably. The coiling disk is constructed on the lower side of the fiber sliver coiling device 5 and is therefore covered by the cover of the fiber sliver coiling device 5 in these figures. During the coiling of the fiber sliver 2, the transport can (which can be referred to as a full can 25 regardless of the actual filling level) is positioned on the can carousel 10. A filling position 14 is defined on the can carousel 10 overlapping with the axis of rotation of the can carousel 10 and is marked by a filling position marking. The coiling disk and the can carousel 10 can be driven in such a way, depending on the conveying speed, that the fiber sliver is coiled in the transport can 25 in a cycloidal manner.

[0054] The transport cans 24, 25 have a cylindrical storage space in a known manner, which is open vertically upward and is bounded vertically downward by a spring-loaded base. As the transport cans 24, 25 are gradually filled with fiber strips 2, the bases of the transport cans 24, 25 move vertically downward due to the deadweight of the fiber strips 2 against the spring force.

[0055] The transport cans are moved as empty cans 24 by a self-propelled transport vehicle 26 to the filling position and after filling are moved away from the filling position 14 as full cans 25. In the present case, the self-propelled transport vehicle 26 is integrated into the bottom end section of the transport cans 24, 25. However, it is also conceivable that the transport cans 24, 25 are mounted on a corresponding self-propelled transport vehicle or are connected to it.

[0056] The self-propelled transporter 26 has two drive wheels 28, which can be driven independently of each other by a drive unit 27 designed as a motor. The drive axes of the drive wheels 28 extend substantially horizontally here. The self-propelled transporter 26 also has four support wheels 29, wherein two are arranged in the region of the vehicle head and two are arranged in the region of the vehicle tail. The support wheels 29 are all supported on the chassis of the self-propelled transporter 26 in a manner that can pivot around a pivot axis, wherein the pivot axis is orthogonal to the drive axis orientation of the drive wheels 28. The self-propelled transporter 26 is therefore designed to perform a translational movement along the longitudinal axis, a rotational movement around the vertical axis, and a combined translation-rotational movement. At least a portion of the support wheels 29 can be spring-loaded in the direction of the pivot axis.

[0057] The self-propelled transporter 26 further comprises an energy store 30 which can supply energy to the drive unit 27. The energy store 30 is designed in the present case as a battery and is connected via an onboard charger to a charging interface 31. The charging interface 31 is in the present case formed on the outer circumference of the self-propelled transporter 26 in the rear region.

[0058] The textile machine 1 comprises a charging station 21 which is designed to charge an energy storage device 30 of a self-propelled transport vehicle 26 and to connect it to the power grid. For this purpose, the charging station 21 has charging contacts 23 which are designed to complement the charging interface 31. In the present example, the charging contacts 23 have two connecting pins 43 which can be inserted into complementary recesses in the charging interface 31. The connecting pins 43 are spring-mounted on the charging contacts 23.

[0059] The charging contacts 23 are movably and in particular spring-loaded in the housing 22 of the charging station 21. In the present case, the charging contacts can be moved parallel to the surface of the movement path, such as in combination with Figure 3 and Figure 4 Of course, a touch protection for the charging contacts 23 can be provided to prevent people from touching the charging contacts 23, especially when the charging contacts 23 are connected to the charging interface 31. The charging station 21 can include a power electronics device instead of the onboard charger of the self-propelled transport vehicle 26.

[0060] The charging station 21 is movably fastened to the frame 7. The charging station 21 is firmly connected to the push element 20 of the moving device 18 of the frame 7. The moving device 18 is designed to move the transport can toward the filling position parallel to the movement path 11 described in further detail below. For this purpose, the moving device 18 has a linear drive 18, to which the push element 20 is firmly connected. The push element 20 can be moved by the linear drive 18 toward the filling position. The moving device 18 is also designed to move the full can 25 away from the filling position 14. For this purpose, the moving device 18 has a further push element (not shown here) that can be moved parallel to the push element 20.

[0061] exist Fig. 9 , an alternative design and arrangement of the charging station 21 and the charging interface 31 is shown. Here, the charging station 21 is integrated into the floor element 9. The charging contacts 23 can be moved in a direction transverse to, in particular orthogonal to, the movement path 11. The charging interface 31 is arranged on the bottom side in the rear region of the self-propelled transport vehicle 26. The charging contacts 23 can thus be moved from the surface of the floor element 9 toward the charging interface 31 until the charging contacts 23 are connected to the charging interface 31. Of course, this alternative design of the charging station 21 and the charging interface 31 can be used for all embodiments of the textile machine 1 disclosed here.

[0062] Figures 1 to 5 The textile machine 1 comprises a frame 7, which comprises a carrier device 8 and a base plate for supporting a part of the fiber coiling device 5 arranged above the can carousel 10. In the present case, the base plate has a base element 9 as well as an ascending ramp 15 and a descending ramp 16. The ascending ramp 15 and the descending ramp 16 are arranged on each side of the base element 9 in order to compensate for the height difference between the placement surface 38 and the surface of the base element 9.

[0063] The surface of the floor element 9 together with the surfaces of the ascending ramp 15 and the descending ramp 16 form a travel path 11 on which a self-propelled transport vehicle 26 can move to transport the transport cans. The transport vehicle 26 is to move along a path marked by a travel track 17, which can be detected by a sensor device 32 of the self-propelled transport vehicle 26. The sensor device 32 is arranged in the head region of the self-propelled transport vehicle 26.

[0064] The travel track 17 consists of a plurality of straight line sections. The travel track 17 can be, for example, an image mark or a magnetic strip on the floor surface. Markings of different positions are provided at defined landmarks of the travel track 17. In addition to the filling position 14 described above, these are also the first turning position 12, the waiting position 13, the second turning position 39, the entry position 40 and the exit position 41 in the present case. These markings can be detected by the sensor device 32 of the self-propelled transport vehicle 27.

[0065] These tags are designed as RFID transponders in the current example. The sensor device 32 includes an RFID reader / writer corresponding thereto. The self-propelled transporter 26 moves along the travel track 17 until the RFID reader / writer passes the RFID transponder. The self-propelled transporter 26 performs the previous movement until it is centered above the tag. The self-propelled transporter 26 establishes a wireless connection with a central control device 37 and notifies the central control device of the identification code read from the RFID transponder. In response, the central control device 37 sends a motion command or a motion command sequence to the self-propelled transporter 26 based on the identification code, and the motion command or motion command sequence is subsequently processed by the transporter. Here, the motion command can include a command about a motion rotating around a specific angle amount, a command about a motion translating to the next tag, and a waiting time in a motion command sequence.

[0066] Specifically, in the present example, the self-propelled transport vehicle 26 first moves upwards along the travel track 17 on the movement path 11, over the ascending ramp 15 and onto the floor element 9. The sensor device 32 detects the magnetic strip and reacts automatically in the event of a possible deviation from the travel track 17. The self-propelled transport vehicle 26 then drives over the marking of the first turning position 12 with the sensor device 32, reads the identification code of the first turning position marking with an RFID reader and sends the identification code to the central control device 37.

[0067] The central control device 37 then informs the self-propelled transport vehicle 26 at the first turning position mark: perform a 90-degree clockwise turn and then back up. The self-propelled transport vehicle 26 executes this instruction and then detects the mark of the waiting position 13. There, the self-propelled transport vehicle 26 receives the instruction to wait from the central control device 37. At the same time, the central control device 37 moves the charging contact 23 toward the charging interface 31 until the two are in contact and the energy storage device 30 is charged.

[0068] Alternatively, it is conceivable to omit the marking of the waiting position 13. Instead, the self-propelled transport vehicle 26 is driven backward until the charging interface 31 contacts the charging contact 23. In this case, the charging contact 23 can be mounted on the housing 22 in a fixed or spring-like manner.

[0069] The transport can 24 remains in the waiting position 13 until the preceding transport can 25 is completely filled. When the preceding transport can 25 has been filled, the displacement device 18 is activated by the control device 36 or the central control device 37 of the textile machine 1, and the linear drive 19 moves the push element 20 together with the transport can 24 toward the filling position 14. The size of the movement path associated with this is selected in this case so that the sensor device 32 can detect the mark of the entry position 40. At the entry position 40, the self-propelled transport vehicle 26 receives the instruction from the central control device 37 to move forward to the next mark (here, the mark of the filling position 14). The self-propelled transport vehicle 26 then moves to the filling position 14 and disconnects the contact between the charging contact 23 and the interface 31 there.

[0070] The displacement device 18 moves the filled full can 25 toward the removal position 41 by means of a further push element (not shown here). The push element 20 and the further push element are spaced apart from one another in such a way that contact between the empty can 24 and the full can 25 is avoided. The size of the displacement path is selected in such a way that the full can 25 can detect the marking of the removal position 41. At the removal position 41, the self-propelled transport vehicle 26 receives the command from the central control device 37 to move forward to the next marking (here, the marking of the second turning position 39).

[0071] Next, the self-propelled transport vehicle 26 with the sensor device 32 passes the mark of the second turning position 39, reads the identification code of the second turning position mark with the RFID reader and sends the corresponding identification code to the central control device 37. The central control device 37 then notifies the self-propelled transport vehicle 26 at the first turning position mark: perform a 90-degree clockwise turn and then drive forward. As a result, the self-propelled transport vehicle 26 can leave the moving path 11. At the same time, the moving device 18 reaches its initial position, so that the new empty can 24 can be moved to the waiting position.

[0072] Described later together Figure 6 and Figure 7In the figure, a textile machine 1 according to the invention is shown in a second embodiment, which is placed on a placement surface 38 of a spinning mill. The textile machine 1 is designed as a double-eye drawing frame and comprises a first fiber strip processing device 3 and a second fiber strip processing device 3', both of which are in the form of a drawing frame 4, which are arranged side by side in a known manner and are connected by a small platform 35. Each fiber strip processing device 3, 3' is provided with a fiber strip coiling device 5 for placing the fiber strip coils into a transport can. Each drawing frame processes a corresponding fiber strip and conveys the fiber strip toward the fiber strip coiling device 5 at an adjustable conveying speed. The first fiber strip processing device 3 and the second fiber strip processing device 3' are designed to be essentially symmetrical to each other. Therefore, the structure of the double-eye drawing frame is subsequently explained with the help of the first fiber strip processing device 3.

[0073] The fiber strip coiling device 5 is similar to Figures 1 to 5 In the second embodiment, the transport cans 24, 25, the self-propelled transport vehicle 26 and the charging station 21 of the first embodiment are used. Therefore, reference is briefly made to Figures 1 to 5 Illustration in the background.

[0074] The textile machine 1 in the second embodiment comprises a frame 7, which comprises a supporting device 8 and a base plate, which is used to support the fiber strip processing device 3 and the fiber strip coiling device 5, which are arranged above the can carousel 10. The charging station 21 is firmly connected to the frame 7 in the second embodiment. In the current case, the base plate has a base element 9 that is flush with the placement surface 38. The surface of the base element 9 forms a movement path 11, on which a self-propelled transport vehicle 26 for transporting transport cans can move. The transport vehicle 26 should move along a route marked with a travel track 17 as described above, and the route has markings of a first turning position 12, a waiting position 13, a filling position 14 and an exit position 41. The corresponding markings designed according to the first embodiment can be detected by the sensor device 32 of the self-propelled transport vehicle 27. As explained in the context of the first embodiment, the self-propelled transport vehicle 26 moves along the travel track 17 with the aid of an identification code.

[0075] Specifically, in the present example, the self-propelled transport vehicle 26 travels on the movement path 11 through the opening on the long side of the frame 7 onto the floor element 9. The sensor device 32 detects the magnetic strip 17. Next, the self-propelled transport vehicle 26 drives over the mark of the first turning position 12 with the sensor device 32, reads the identification code of the first turning position mark with the RFID reader and sends the identification code to the central control device 37.

[0076] The central control device 37 then informs the self-propelled transport vehicle 26 at the first turning position mark: perform a 90 degree counterclockwise turn and then wait. Therefore, in the present case, the first turning position 12 and the waiting position 13 coincide. The waiting position 13 is arranged on the floor element 9. The central control device 37 and / or the control device 36 of the textile machine 1 then moves the charging contact 23 of the charging station 21 towards the charging interface 31 until the two are in contact and the energy storage device 30 is charged.

[0077] The transport can 24 remains in the waiting position 13 until the preceding transport can 25 is completely filled. When the preceding transport can 25 has been filled, a signal is sent from the control device 36 of the textile machine 1 to the central control device 37 that the filling process is finished. The central control device 37 itself sends a movement command "move forward to the next mark" to the empty can 24 and the full can 25. The full can 25 is thus moved from the can carousel 10 and replaced by the empty can 24.

[0078] Therefore, the displacement device 18 can be omitted with the second embodiment. However, it is also conceivable that the second embodiment is equipped with the displacement device 18 and that the can change is carried out in a manner similar to the first embodiment, wherein a marking of the entry position 40 is additionally provided.

[0079] Finally, the self-propelled transport vehicle 26 moves along the travel path 11 through an opening of the machine frame 7 arranged at the end side.

[0080] Depend on Figure 7 Combination Fig. 9 It can be seen that in the area of ​​the waiting position 13, a cleaning device 33 is integrated into the floor element 9. A plurality of cleaning openings 34 are arranged around the waiting position 13, which are fluidically connected to a central suction device 42. If an empty can 24 is positioned in the waiting position 13, the energy store 30 can be charged and the empty can 24 can be sucked from below at the same time. This suction can remove dirt from the wheels, which could cause a blockage of the wheels.

[0081] exist Figure 8 In the embodiment, a first textile machine 1 according to the invention and a second textile machine 1' according to the invention are arranged parallel to each other, both of which are designed in the third embodiment. The third embodiment differs from the second embodiment only in the positioning of the waiting position 13 and the charging station 21. In this regard, with regard to the common points, reference is briefly made to the above description in the context of the second embodiment.

[0082] In a third embodiment of the textile machine 1, the travel path 11 extends over the base element 9 and the support surface 38. The waiting position 13 is arranged on the support surface 38. The shortest distance between the waiting position 13 and the machine frame 7 is at most the clear width B of the travel path 11 in the region of the base element 9 of the machine frame 7. Specifically, the distance between the waiting position 13 and the machine frame 7 is half the clear width B of the travel path 11 in the region of the base element 9 of the machine frame 7. The charging station 21 is arranged in such a way that when an empty can 24 is placed on the waiting position 13, contact can be established between the charging contacts 23 and the charging interface 31.

[0083] For the sake of clarity, the clear width B of the travel path 11 is Figure 6 The clear width B describes the maximum width of an object that can be moved along the travel rails 17 in the area of ​​the floor element 9 through the travel path 11. The clear width B can therefore be referred to as the maximum passage width. The openings on the long sides and the end sides of the frame 7 have a width at least equal to the clear width B.

[0084] A passage is formed between the first textile machine 1 and the second textile machine 1', which passage has a width at least equal to the clear width B. A waiting position 13' is arranged in the passage, at which the empty cans of the second fiber processing device 3' of the first textile machine 1 and the empty cans of the first fiber processing device 3 of the second textile machine can be placed. The charging station 21' is arranged in such a way that when the empty can 24 is placed in the waiting position 13', contact can be established between the charging contacts 23 of the charging station 21' and the charging interface 31 of the empty can 24.

[0085] For this purpose, the control device 36 of the first textile machine 1 and / or the control device 36 of the second textile machine 1 ′ can move the charging contact 23 . In other words, the three charging stations are connected to the control devices of one or more textile machines. It is also conceivable that the charging stations are directly connected to the central control device 37 .

[0086] exist Fig.10 1 shows a method for operating a construction unit consisting of a self-propelled transport vehicle for transporting cans and the previously described textile machine. Starting from the starting point S of the method, the self-propelled transport vehicle 26 moves to the waiting position 13 of the textile machine in process step V10.

[0087] While the self-propelled transport vehicle 26 is positioned at the waiting position 13, in process step V20, the energy storage device 30 of the self-propelled transport vehicle 27 is charged by means of the charging station 21. To charge the energy storage device 30, the charging contacts 23 of the charging station 21 can be moved toward the waiting position 13 until the charging contacts 23 come into contact with the charging interface 31 of the self-propelled transport vehicle 27. Alternatively or in combination, to charge the energy storage device 30 of the self-propelled transport vehicle 27, the self-propelled transport vehicle 26 can be moved toward the charging station 21 until the charging interface 31 comes into contact with the charging contacts 23 of the charging station 21.

[0088] Next, in process step V30, the self-propelled transport carriage 27 is moved from the waiting position 13 to the filling position 14. While the self-propelled transport carriage 26 is positioned at the filling position 14, in process step V40, the fiber loop is placed in a transport can.

[0089] In step V50 , the self-propelled transport vehicle 26 is moved away from the filling location 14 when the transport can is completely filled.

[0090] The movement of the self-propelled transport vehicle 27 to the waiting position 13 in step V10 , the movement of the self-propelled transport vehicle 27 from the waiting position 13 to the filling position 14 and / or the movement of the self-propelled transport vehicle 27 away from the filling position 14 are all controlled by the central control device 37 .
