Description

[0001] The invention relates to a device for the semi-automatic preparation for the reuse of winding cores and a method for the semi-automatic preparation for the reuse of the winding cores using the device.

[0002] In the production of various products, raw materials are often delivered on rolls and used as so-called "coilware." The rolls (coils) are constructed in such a way that the raw material to be processed is wound or wound onto a core or spool. The production process chain often includes various roll-to-roll processes in which the material is processed continuously. For a continuous process, the material from the rolls is spliced ​​together to form an endless web. This is done, for example, by an automated splicing process. To prevent breakage, remnants of the material remain as a buffer on the core (winding core, coil core). Before the core can be fed into a new winding process, the residual material on the core must be removed, and the core may need to be cleaned.

[0003] It is generally known that the cores are prepared using a purely manual process along with the remaining material. However, a high degree of manual labor in the process chain leads to high personnel costs. Furthermore, manual processes can create unergonomic working conditions for employees. Especially with high production volumes, a manual preparation process can negatively impact the entire manufacturing process.

[0004] Furthermore, highly automated devices for preparing cores are already known. These include, for example, fully automated process plants. In such devices, the cores are prepared fully automatically, for example, mechanically, chemically, or using ultrasound. Such highly automated processes have long cycle times, low flexibility, and use large quantities of liquids. To ensure a continuous supply of cores, the required number of cores in circulation must be high in such devices. Highly automated devices are therefore associated with high investment costs.

[0005] In the technical field of battery cell manufacturing, particularly the production of battery electrodes, production takes place in a cleanroom or dry room. Among other things, anode and cathode materials on reels are used to manufacture the battery electrodes. Due to the large space requirements and high fluid consumption, highly automated equipment for preparing the winding cores cannot be used in such a dry room. However, for efficient battery cell production, it is essential that the equipment for preparing the cores for reuse is directly integrated into the factory's material flow.

[0006] German patent DE 30 30 845 A1 describes a device for unwinding a web, in particular a paper web, from a core. The device has a fully automated station for supporting the core carrying the paper web, in which the core is fixed in a predetermined position and can be driven to rotate in order to unwind the paper web. Before unwinding, the cores to be unwound are manually placed on a platform.

[0007] EP 1 667 927 A1 describes a highly automated device for reprocessing used cores for material rolls. The cores are fed to the reprocessing unit via a conveyor-like feeder with separation elements. The device includes a fully automatic removal device for stripping the residual material from the cores and a subsequent cleaning station with a container filled with hot water.

[0008] Another well-known approach is to use disposable cores that are discarded after a single use. However, from an ecological and economic perspective, this approach is not sustainable.

[0009] The object of the present invention is to provide an improved device for preparing winding cores for reuse, in which the aforementioned disadvantages are at least partially overcome. Furthermore, it is an object of the present invention to provide an improved method for preparing winding cores for reuse, in which the aforementioned disadvantages are at least partially overcome.

[0010] This problem is solved by the device according to claim 1 and the method according to claim 11.

[0011] Further advantageous embodiments of the invention will become apparent from the dependent claims and the following description of preferred embodiments of the present invention.

[0012] A first aspect of the invention relates to a device for the semi-automatic preparation of winding cores for reuse, comprising a preparation device for preparing the winding cores for reuse and an interface device for loading with winding cores to be prepared, wherein the preparation device can be loaded with the winding cores to be prepared via the interface device using a mobile transport device.

[0013] The device can be a workstation. The device can be a workstation within a process chain. The workstation can be an associated part of a larger process chain. In one embodiment, the device can be a workstation in a process chain for the production of battery electrodes or battery cells, located in a dry room or cleanroom. The device can be used for the production of battery electrodes for the automotive sector. Furthermore, the device can be used, for example, for the production of battery electrodes for IT, smartphones, stationary storage devices, or other technical fields.

[0014] In this context, the term "semi-automatic" means that the device combines manual and automatic or automated components. Unlike a fully automatic device, in a semi-automatic device, some components or parts thereof are designed to be operated with the assistance of an operator. Other components or parts, however, are designed for fully automatic operation. These components or parts can be operated without direct operator interaction.

[0015] Preparing cores for reuse can include unwinding residual material from the winding spool. Preparing cores for reuse can include cleaning the winding spool. Preparing cores for reuse can include unwinding residual material and cleaning the winding spool. Alternatively, or in addition to unwinding the residual material, it can be cut off the core.

[0016] The preparation device and the interface device are arranged in a coupled manner.

[0017] The preparation device can be designed to be operated manually or partially manually. The preparation device can be designed to prepare one winding core. The preparation device can be designed to prepare several winding cores simultaneously.

[0018] The interface device can be configured for semi-automatic or fully automatic operation. The interface device can be fully automatically loaded with the winding cores to be prepared via the mobile transport device.

[0019] In this context, "loadable" means that the device or preparation device can be supplied via the interface device using the mobile transport device. "Loadable" in this context also means that the device or preparation device can be equipped with the mobile transport device via the interface device.

[0020] The mobile transport device can deliver the winding cores to be prepared. The mobile transport device can pick up the winding cores to be prepared from another device or workstation within the higher-level process chain and deliver them to the device according to the invention. The mobile transport device can be selected according to a requirements profile and / or a degree of automation. The mobile transport device can be an automatic mobile transport device. The mobile transport device can be an autonomously functioning mobile transport device. The mobile transport device can be a manual mobile transport device. The mobile transport device can be, for example, an automated guided vehicle (AGV), a pallet truck, or a material carrier with wheels.The device can be designed such that the preparation device can be loaded with winding cores from various mobile transport devices via the interface device. The mobile transport device can include a holder or support for one or more winding cores. Alternatively, the mobile transport device can include a holder or support for a transport box. The transport box can be designed to hold the winding cores.

[0021] The device according to the invention allows for a more compact workstation for preparing winding cores for reuse compared to a fully automated device. The device according to the invention can be operated in a cleanroom or dry room. The device according to the invention reduces costs compared to a fully automated device.

The device according to the invention eliminates the need for heavy lifting by employees.The device according to the invention reduces the number of winding cores in circulation compared to fully automated devices. The device according to the invention allows the winding cores to be reused multiple times compared to disposable cores.

[0022] There are embodiments in which the device can be supplied with the winding cores via the interface device, regardless of the operating state of the preparation device.

[0023] The device can be loaded with winding cores to be prepared while one or more winding cores are being prepared in the preparation device. The loading process can be decoupled from the operating state of the preparation device. The preparation device can be in an active operating state while the device is being loaded with winding cores via the interface device. Alternatively, the preparation device can be in an inactive operating state while the device is being loaded with winding cores via the interface device.

[0024] This optimizes the work process. This allows downtime to be avoided or reduced. This allows working conditions for employees to be designed more ergonomically than with manual preparation. This allows the preparation device to be used efficiently. This allows the device according to the invention to be loaded flexibly.

[0025] There are embodiments in which the interface device further comprises an intermediate storage unit for the winding cores to be prepared, which is coupled to the preparation device.

[0026] The intermediate storage unit can function as a material storage unit. The intermediate storage unit can function as a buffer. The intermediate storage unit can be designed to store or buffer several winding cores to be prepared. The intermediate storage unit can be designed to accommodate several winding cores to be prepared.

[0027] The intermediate storage unit can be designed as a chute. The intermediate storage unit can include a chute-like section. The material storage unit can essentially function like a Kanban rack. The material storage unit can essentially be designed like a Kanban rack. The intermediate storage unit can be designed and coupled to the preparation device in such a way that automatic material feeding of the winding cores to be prepared to the preparation device is possible. The coupling can be made via one side of the intermediate storage unit.

[0028] The intermediate storage unit is designed such that the winding cores can roll along it. The intermediate storage unit can include a rail-like section. The winding cores can roll along the rail-like intermediate storage unit. The winding cores can roll along the rail-like intermediate storage unit to the preparation device.

[0029] Alternatively or additionally, the intermediate storage unit can include a conveyor belt. The conveyor belt can include an electric drive.

[0030] In another embodiment, the intermediate storage unit can comprise a transport box. In this case, the preparation device can be manually loaded from the transport box.

[0031] This decouples the loading or delivery via the mobile transport device from the preparation cycle of the preparation device. This makes the preparation device independent of the loading via the mobile transport device. As a result, the device according to the invention can be loaded efficiently by the mobile transport device. This allows for more ergonomic working conditions for employees compared to manual loading or delivery. This also allows the preparation device to be operated independently of the number of winding cores to be prepared in the intermediate storage area.

[0032] There are embodiments in which the interface device further includes a delivery interface for feeding with the mobile transport device, which is coupled to the intermediate storage.

[0033] The delivery interface can be coupled to the intermediate storage in such a way that the winding cores can roll from the delivery interface into the intermediate storage.

[0034] The delivery interface is located on the side of the interface device that is accessible to the mobile transport device. The delivery interface serves to transfer the winding cores from the mobile transport device. The delivery interface can be designed to interact automatically with the mobile transport device during loading.

[0035] The delivery interface and the mobile transport device can be coordinated. The mobile transport device can also include an interface for receiving the winding cores. The delivery interface can interact with the interface for receiving the winding cores on the mobile transport device.

[0036] This allows the loading of the device according to the invention to be automated. This allows the loading of the device according to the invention to be carried out independently of an employee. This saves personnel. This allows the working conditions for employees to be designed more ergonomically than with manual preparation. This allows the number of winding cores in circulation to be reduced compared to fully automatic devices.

[0037] There are embodiments in which the delivery interface includes an adaptable receiving device for receiving the winding cores to be prepared.

[0038] The adaptable receiving device can be adjustable. The adaptable receiving device can be adapted via a relative movement to the interface device or intermediate storage. For example, the adaptable receiving device can be adjustable in a vertical direction. The vertical adjustment can be achieved using suitable mechanical and / or electrical components. Control can be provided by a control unit. The control of the receiving device can be synchronized with the position of the mobile transport device. The receiving device can interact with the mobile transport device via the control unit.

[0039] Alternatively or additionally, the mobile transport device can include an adaptable receiving unit for receiving the winding cores to be prepared. The optional adaptable receiving unit on the mobile transport device can be designed and configured essentially like the adaptable receiving unit of the delivery interface. The integration of the adaptable receiving unit into the mobile transport device can be achieved using methods familiar to those skilled in the art (design-related methods).

[0040] The receiving device can include receiving blocks. These blocks are designed to hold the winding cores to be prepared. The receiving blocks can, for example, have a V-shaped support surface. Alternatively, they can have a rounded support surface or another suitable support surface. The specific design and construction of the receiving device can vary depending on its function.

[0041] The following describes an exemplary operation of the adaptable receiving device, in which the device is loaded with winding cores (winding cores to be prepared) via the interface device using the mobile transport device. In a first operating state, the mobile transport device moves towards the interface device with a winding core. During this first operating state, the receiving blocks of the adaptable receiving device are at a height lower than the height of the winding core on the mobile transport device (alternatively: lower than the height of a support for the winding core on the mobile transport device). In a second operating state, the winding core is located above the receiving blocks. During this second operating state, the receiving blocks are moved upwards to lift the winding core out of the mobile transport device.In a third operating state, the mobile transport device, without the winding core, moves out of the area of ​​the interface device. The receiving blocks then move downwards with the winding core and place it down. Once the receiving blocks are back in their starting position, the winding cores roll from the delivery interface onto the intermediate storage area.

[0042] This automates the loading of the winding cores to be prepared. This makes the device semi-automated. This saves on personnel. This allows for more ergonomic working conditions for employees compared to manual preparation. This reduces the number of winding cores in circulation compared to fully automated devices.

[0043] There are embodiments in which the interface device further comprises a singulation device for singulating the winding cores to be prepared, which is arranged at the intermediate storage.

[0044] The singulation device is designed to separate the winding cores to be prepared before they enter the preparation device from the interface device. The singulation device can separate the winding cores to be prepared. The singulation device can be arranged at the intermediate storage area in a transition zone to the preparation device.

[0045] The singulation device can include mechanical components. Alternatively or additionally, the singulation device can include electrical components. Alternatively or additionally, the singulation device can include electromechanical components. Actuation of the singulation device can be mechanical or electromechanical. For example, the singulation device can be actuated via an operating device. The operating device can be foot-operated. The operating device can be hand-operated. This allows, for example, an employee to operate the singulation device as soon as they need another winding core in the preparation device.

[0046] This allows for more ergonomic working conditions for employees compared to manual preparation. The preparation device can operate independently or decoupled from the fill level of the intermediate storage. This allows the employee to control the feeding of the preparation device.

[0047] There are embodiments in which the preparation device includes a withdrawal device with which winding cores can be coupled.

[0048] The dispensing device is designed such that winding cores can be coupled to it. The dispensing device may include a receptacle for one or more winding cores. The dispensing device or the receptacle may include a support on both sides for receiving the winding cores. The dispensing device may be designed such that the winding core is rotatably mounted within it. For the rotatable mounting of the winding cores, the dispensing device may additionally include one or more rotatable rollers. The roller may be electrically driven.

[0049] A winding core, previously separated by the singulation device, can be fed into the take-off device. The winding core can automatically fall or roll into the take-off device after the singulation device has been activated. In the take-off device, any residual material on the winding core is separated or unwound. This separation or unwinding can be done manually by an operator. The unwound winding core can then be cleaned. This cleaning can also be done manually; for example, the operator can wipe the core with an optional cleaning agent.

[0050] This allows for more efficient preparation of the winding cores for reuse compared to manual preparation processes. It also allows for more ergonomic working conditions for employees compared to manual preparation. Furthermore, it keeps equipment costs lower than for a fully automated system. Finally, it enables employees to identify and reject defective winding cores through visual inspection.

[0051] Optionally, the fume hood can include an additional drive. This drive can be electric, for example, an electric motor. Furthermore, optionally, the fume hood can include an automatic cleaning device. This cleaning device can be operated, for example, mechanically and / or with a cleaning agent (e.g., alcohol).

[0052] Optionally, the preparation device can include a logistics interface. This interface could, for example, be an interface to a Manufacturing Execution System (MES). The logistics interface can also include an identification device or a scanning unit. If a logistics interface is present, each winding core can include an identification element, such as a chip or a code. This allows for the transmission and storage of additional information. For example, employees can record defective cores in the system or automate the collection and delivery of transport boxes or containers for the remaining material.

[0053] The aforementioned optional modifications or components can be combined with the device according to the invention as desired. This depends on the specific requirements. The optional modifications or components can increase the level of automation of the device or the preparation device.

[0054] The components described as optional also provide the advantages described above. These optional components can further enhance or improve the advantages described above.

[0055] There are embodiments in which the preparation device includes a removal interface for removing the winding cores prepared for reuse.

[0056] Removal can be done manually. The removal interface can be designed so that the employee can remove the prepared winding cores via the removal interface. The removal interface can optionally include a locking mechanism. Access to the preparation device can be ensured via the removal interface.

[0057] Alternatively, the removal process can be automated. For example, removal can be carried out by a robot or a suitable AGV (Automated Guided Vehicle). Removal can be automated, for instance, if the preparation of the winding cores (unwinding, mechanical cleaning) is also automated.

[0058] The device can include a transport box. The transport box can be designed to hold the prepared winding cores. The transport box can be positioned, for example, behind or beside the employee. The prepared winding core can be removed via the dispensing interface and collected in the transport box. The prepared winding cores can then be made available again for the production process.

[0059] This allows the device according to the invention to be simplified compared to fully automatic devices. Defective winding cores can be sorted out by visual inspection by an employee. This allows the device according to the invention to be designed more compactly overall compared to fully automatic devices. As a result, the costs for the device according to the invention can be kept lower than for a fully automatic device.

[0060] There are embodiments in which the preparation device includes a receiving container designed to directly receive residual material separated from the winding core.

[0061] The receiving container can be a recycling container. It can be located below the preparation device. Direct collection of residual material means that the receiving container is arranged or positioned so that the residual material falls directly into it after unwinding. This eliminates the need for additional transfer of the residual material by the operator. Once the receiving container is full, it can be replaced with an empty one. If a winding core is being prepared with a different type of residual material, the receiving container can be exchanged. This allows the residual material to be recycled separately.

[0062] This optimizes the work process. It allows downtime to be avoided or reduced. It enables more ergonomic working conditions for employees compared to manual preparation. It allows for efficient use of the preparation equipment. It saves work steps. It enables the single-stream recycling of residual material on the winding core.

[0063] There are embodiments that further include an enclosure, wherein the enclosure surrounds the preparation device.

[0064] The enclosure can be cabin-like. The enclosure can be a cleaning room. The enclosure can be transparent or semi-transparent. The enclosure can include an extraction system. The enclosure can be fully enclosed. The enclosure can optionally include an access door at the dispensing interface. The enclosure can optionally include an access door at the singulation device or in the intermediate storage area. This allows the enclosure to be opened or closed as needed. The enclosure and / or the access doors can be designed like a fume hood.

[0065] This protects the employee from particle emissions. It also protects the surrounding production area, such as the cleanroom for battery cell production. This allows the device to be operated in a cleanroom or dry environment.

[0066] A second aspect of the invention relates to a method for the semi-automatic preparation of winding cores for reuse, comprising: - Provision of the device according to the invention; - Delivery and loading of winding cores to be prepared with a mobile transport device via an interface device to a preparation device; - Preparing for the reuse of winding cores within the preparation device; and - Removing winding cores prepared for reuse from the preparation device.

[0067] The provision of the device according to the invention corresponds to a device for the semi-automatic preparation for the reuse of winding cores with the features described above. The exact design of the device can be selected according to the requirements profile.

[0068] Delivery is carried out via the mobile transport device. The mobile transport device can be one of the previously described mobile transport devices. Multiple mobile transport devices can also deliver and load the winding cores to be prepared. Delivery and loading can be automated. Delivery and loading can be controlled by a system. Delivery and loading can be autonomous.

[0069] Preparing winding cores for reuse can be done manually. Preparing winding cores for reuse can also be done semi-automatically. Preparation involves interaction between an operator and the preparation device. The degree of automation can be selected or increased according to the requirements of the device according to the invention.

[0070] The prepared winding cores can be removed manually. Alternatively, an employee can remove them. The employee can then remove the prepared winding cores from the preparation device.

[0071] Alternatively, the removal process can be automated. For example, removal can be carried out by a robot or a suitable AGV (Automated Guided Vehicle). Removal can be automated, for instance, if the preparation of the winding cores (unwinding, mechanical cleaning) is also automated.

[0072] The advantages described above for the device according to the invention apply in the same way to the method according to the invention.

[0073] Exemplary embodiments of the invention are now described by way of example and with reference to the accompanying drawings. Identical or similar parts are designated by uniform reference numerals. The drawings show: Fig. 1 schematically a first embodiment of a device according to the invention; Fig. 2 schematically a second embodiment of the device according to the invention; Fig. 3A to 3D different examples of a mobile transport device; Fig. 4A, Fig. 4B Two embodiments for receiving winding cores using the mobile transport device; Fig. 5A, Fig. 5B two embodiments of a delivery interface of an interface device; Fig. 6 a schematic representation of a process for loading using the mobile transport device; Fig. 7 a schematic representation of an embodiment of a preparation device; Fig. 8 a third embodiment of the device according to the invention; and Fig. 9 schematically a method according to the invention.

[0074] Fig. Figure 1 schematically shows a first embodiment of a device 1 according to the invention. The device 1 comprises a preparation device 3 and an interface device 5. To prepare winding cores 50 for reuse, the winding cores 50 with residual material 51 are delivered by a mobile transport device 70. The mobile transport device 70 then feeds the preparation device 3 with the winding cores 50, 51 to be prepared via the interface device 5.

[0075] Device 1 in Fig. 1 further includes a receiving container 30, an enclosure 40 and a transport box 60.

[0076] The receiving container 30 serves to directly receive residual material 51 that is separated from the winding core 50. The receiving container 30 is arranged below the preparation device 3.

[0077] The preparation device 3 is surrounded by the enclosure 40. The enclosure 40 encloses the preparation device 3. The receiving container 30 is arranged inside the enclosure 40. The enclosure 40 includes an optional extraction system (not shown). The preparation device 3 is accessible via a sliding first access door 41. During loading with the mobile transport device 70, the preparation device 3 is accessible via the interface device 5 through a sliding second access door 43. After loading, the second access door 43 can be closed.

[0078] The transport box 60 is used to hold prepared winding cores 50. After the winding cores 50 have been prepared, they are placed in the transport box 60. The transport box 60 is positioned so that it is ergonomically accessible to an employee.

[0079] Fig. Figure 1 shows the device 1 in an operating state with an exemplary employee M. Employee M stands outside the enclosure 40 in front of the preparation device 3. The first access door 41 is open. Employee M operates the preparation device 3 through the first access door 41. A winding core 50 with residual material 51 is inserted into the preparation device 3. Employee M can remove the residual material 51 from the winding core 50 and optionally wipe or clean the winding core 50. The residual material 51 is picked up directly by the receiving container 30 located below it. After preparation, employee M places the winding core 50 into the transport box 60. The preparation direction 3 is fed or supplied via the interface device 5 using the mobile transport device 70 from another side of the enclosure 40. The feeding or supplying takes place while employee M is standing at his work area.

[0080] Fig. Figure 2 shows a second embodiment of the device 1 according to the invention. The second embodiment of the device 1 differs from the first embodiment in that the second embodiment is extended by additional components. The additional components are optional and can be combined as desired. In contrast to Fig. 1 includes the interface device 5 of the device 1 in Fig. 2 furthermore an intermediate storage device 7, a delivery interface 9 and a singulation device 13. In contrast to Fig. 1 includes the preparation device 3 of the device 1 in Fig. 2 further a withdrawal device 15. The device 1 can be supplied with the winding cores 50 to be prepared with residual material 51 via the interface device 5, independently of an operating state of the preparation device 3.

[0081] The intermediate storage unit 7 is designed like a chute. It slopes downwards towards the preparation device 3. The intermediate storage unit 7 receives several winding cores 50 to be prepared, along with residual material 51. The winding cores 50 are arranged one behind the other on the intermediate storage unit 7. Due to the chute-like design of the intermediate storage unit 7, the winding cores 50 roll from the delivery interface 9 towards the preparation device 3 without any additional drive.

[0082] The delivery interface 9 is used for loading with the mobile transport device 70. The delivery interface 9 is coupled to the intermediate storage unit 7. The coupling is located on the side of the interface device 5 that is opposite the preparation device 3. The coupling is designed such that the winding cores 50 can roll from the delivery interface 9 into the intermediate storage unit 7. Regardless of the operating state of the preparation device 3, the device 1 is loaded with winding cores 50, 51 via the delivery interface 9.

[0083] The singulation device 13 is arranged at the intermediate storage unit 7. The singulation device 13 is arranged in the area in front of the preparation device 3. In Fig. Figure 2 shows the preparation device 3 in an active state. In the active state, the singulation device 13 extends beyond the intermediate storage unit 7. This prevents the winding cores 50 and 51 from rolling further. In a non-active state (not shown), the singulation device 13 does not extend beyond the intermediate storage unit 7. In the non-active state, the singulation device 13 is retracted. As a result, the winding cores 50 and 51 continue to roll towards the preparation device 3. The singulation device 13 is in Fig. 2. For example, an actuating device 13a is used to switch between the active and inactive states. For example, the actuating device 13a can be actuated by the foot of employee M.

[0084] The take-off device 15 is coupled to the winding cores 50 or the winding cores 50 with residual material 51 in the operating state. The coupling between the take-off device 15 and the winding core 50 exists regardless of whether residual material 51 is present on the winding core 50 or not. A winding core 50 with residual material 51 to be prepared is separated by the singulation device 13 and rolls along the intermediate storage 7 to the take-off device 15. The take-off device 15 can be designed such that the winding core 50 falls or rolls directly into the take-off device 15 after rolling from the intermediate storage 7.

[0085] The Fig. Figures 3A to 3D show four different embodiments of a mobile transport device 70, 70A, 70B, 70C, 70D. The device 1 according to the invention is not limited to the use of a specific mobile transport device 70.

[0086] Fig. Figure 3A shows an AGV (Automated Guided Vehicle) with a double-sided receptacle for the winding core 50, 51 as a mobile transport device 70A.

[0087] Fig. Figure 3B shows an AGV (cantilever AGV) with a pin for receiving the winding core 50, 51 as a mobile transport device 70B.

[0088] Fig. 3C shows a manual electric forklift or pallet truck as a mobile transport device 70C.

[0089] Fig. 3D shows a manual goods carrier as a mobile transport device 70D.

[0090] The Fig. 4A and Fig. Figures 4B each show an embodiment for receiving winding cores 50, 51 using the mobile transport device 70.

[0091] Fig. Figure 4A shows the mounting of the winding core 50, 51 with a double-sided mounting 71. The double-sided mounting 71 comprises two mounting blocks, each with a V-shaped contact surface. A cylindrical section projects from both sides of the winding core 50, 51. The double-sided mounting 71 receives the winding core 50, 51 via the double-sided cylindrical section.

[0092] Fig. Figure 4B shows the mounting of the winding core 50, 51 with a pin for mounting 71 (mounting pin 71). The winding core 50 is penetrated by a round recess. The round recess is arranged concentrically or coaxially to an outer geometry of the cylindrical winding core 50. The mounting pin 71 projects into the round recess and receives the winding core 50.

[0093] The Fig. 5A and Fig. Figure 5B shows an embodiment of the delivery interface 9. In both embodiments, the delivery interface 9 comprises an adaptable receiving device 11. A winding core 50, 51 to be prepared is received via the receiving device 11. The delivery interface 11 is adaptable or adjustable in a vertical direction. The adaptation of the delivery interface 11 is carried out via a control unit (not shown). Fig. 5A and Fig. In Figure 5B, the delivery interface 11 is exemplified by receiving blocks with a V-shaped contact surface. The receiving blocks are each arranged on an inner side of the rail-like delivery interface 9.

[0094] Fig. Figure 5A shows an embodiment in which the mobile transport device 70 includes a core support on both sides. Loading or delivery of the winding cores 50, 51 to be prepared is carried out from the front. The mobile transport device 70 for the embodiment in Fig. 5A, for example, is one of the ones in the Fig. 3A, Fig. 3C or Fig. 3D representation of mobile transport devices 70A, 70C or 70D. The mobile transport device 70 moves between the rail-like delivery interface to load the interface device 5 with the winding core 50, 51 to be prepared.

[0095] Fig. Figure 5B shows an embodiment in which the mobile transport device 70 has a receiving pin 71 or a core support on both sides.

The several delivery interfaces 9 are arranged parallel to one another. Feeding is carried out in parallel via several mobile transport devices 70. Optionally, the winding cores 50, 51 can be positioned in a workpiece carrier via the delivery interface 9. The intermediate storage 7 comprises a conveyor belt-like section. The conveyor belt-like section is designed such that the winding cores 50, 51, fed in parallel to one another and to be prepared, are transported to the preparation device 3. In the third embodiment, the removal of the prepared winding cores 50 can, for example, be automated.

[0106] Fig.Figure 9 schematically shows a method 100 according to the invention. The method 100 comprises four process steps. The process steps are represented as blocks 110, 120, 130, 140. The blocks are arranged one below the other and each is connected by arrows.

[0107] The device 1 according to the invention is provided in block 110.

[0108] In block 120, the winding cores 50, 51 to be prepared are delivered with the mobile transport device 70 and fed to the preparation device 3 via the interface device 5.

[0109] In block 130, the winding cores 50 are prepared within the preparation device 3. The residual material 51 is removed from the winding cores 50. Optionally, the winding cores 50 are wiped and / or cleaned with a cleaning agent.

[0110] In block 140, the prepared winding cores 50 are removed from the preparation device 3 for reuse. The prepared winding cores 50 can then be placed in the transport box 60.
