Description

Technical Field

[0001] This application claims priority to Korean Patent Application No. 10-2021-0170702, filed on December 2, 2021, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to an automated conveying and feeding device for various raw materials and auxiliary materials provided in rolls, and more particularly to an automated conveying and feeding device capable of automatically performing a series of feeding and dispensing operations, wherein the rolled materials are automatically released from a storage tank and delivered to an overhead lifting transport system (OHT), and the rolled materials are received when the OHT arrives at a facility designated as its destination. Background Technology

[0003] With the development of technology and the increasing demand for mobile devices, the demand for secondary batteries as an alternative to fossil fuels has increased rapidly, and people have conducted a lot of research on secondary batteries that can meet various needs.

[0004] In terms of battery casing shape, secondary batteries are mainly divided into cylindrical batteries with electrode components embedded in cylindrical metal cans, prismatic batteries with electrode components embedded in prismatic metal cans, and pouch batteries with electrode components embedded in pouch-shaped casings made of aluminum laminates. Regarding materials, there is also a high demand for lithium secondary batteries with high energy density, high discharge voltage, and good output stability, such as lithium-ion batteries and lithium-ion polymer batteries.

[0005] The electrode assembly embedded in the battery casing is a rechargeable power generation device made of a positive / separator / negative electrode stacked structure. Electrode assemblies are divided into jelly roll electrode assemblies and stacked electrode assemblies. Jelly roll electrode assemblies are formed by placing a separator between elongated sheet-like positive and negative electrodes coated with active material and winding the positive and negative electrodes and the separator. Stacked electrode assemblies are formed by sequentially stacking multiple positive and negative electrodes, each having a predetermined size, with a separator layer between the positive and negative electrodes. Furthermore, as an electrode assembly with a further advanced structure, a hybrid of jelly roll electrode assemblies and stacked electrode assemblies, a stacked / folded electrode assembly has also been developed. This stacked / folded electrode assembly is formed by folding a complete battery with a positive / separator / negative electrode structure of a predetermined unit size or a dual battery using a long, continuous separator with a positive (negative) / separator / negative (positive) / separator / positive (negative) electrode structure of a predetermined unit size.

[0006] Here, the positive electrode sheet, separator sheet and negative electrode sheet constituting the electrode assembly including the stacked structure of unit electrodes are provided in the form of rolls, and the raw material and auxiliary material sheets are continuously supplied and processed in a roll-to-roll manner between the unwinding machine and the rewinding machine.

[0007] When sheets supplied in roll form are collectively referred to as roll materials, a series of manufacturing processes begin with the installation of the roll materials on the winding machine. Therefore, in order to ensure that the manufacturing process proceeds smoothly and without interruption, the roll materials should be supplied in a timely manner and installed on the winding machine.

[0008] However, in the past, rolled materials were manually loaded from the warehouse using trolleys, then transported to the corresponding winding machines and manually fed into them. Each winding machine required several rolls of material per reference time, making the simultaneous transport of these rolls a heavy task for the operators.

[0009] When rushing to process large volumes of rolled material, raw materials and auxiliary materials may be damaged during processing, and quality problems may arise due to inadequate manufacturing management—this is a major concern. Furthermore, when tasks are rushed, there is a risk of accidents due to errors in handling heavy rolled material. Therefore, a series of processes requiring automation, including the release, conveying, and input of rolled material, have begun to emerge.

[0012] (Patent Document 1) Japanese Patent Registration No. 2993895 (Registration Date: October 22, 1999) Summary of the Invention

[0013] [Technical Issues]

[0014] The purpose of this invention is to provide an automatic conveying and feeding device for rolled materials, which can automatically perform a series of processes such as loading, releasing, conveying and inputting rolled materials.

[0015] [Technical Solution]

[0016] This invention provides an automated conveying and feeding device for rolled materials. In one embodiment, the automated conveying and feeding device for rolled materials includes: a roll buffer configured to receive rolled materials loaded on a carriage in the X-axis direction and convey the received rolled materials in the YZ plane; a conveying device configured to receive rolled materials from the roll buffer in the X-axis direction, move the rolled materials to a set position in the XY plane while they are loaded on the conveying device, and convey the rolled materials upward in the Z-axis direction; and an overhead lifting transport system (OHT) configured to receive rolled materials loaded on the conveying device which has moved upward in the Z-axis direction, and having at least one or more track-guided vehicles configured to move along a conveying track to a destination.

[0017] In a specific implementation, the movement of the rolled material between the roll buffer and the conveying device, and between the conveying device and the track-guided vehicle, can be done in a rod-to-rod manner.

[0018] Therefore, rods configured to be inserted into the hollow hub of the rolled material can be installed on each of the roll buffer, conveyor, and track-guided vehicle.

[0019] Furthermore, a push unit configured to push the rolled material loaded through the rod via the hollow hub can be provided on each of the roll buffer, the conveyor, and the track-guided vehicle.

[0020] In one embodiment, the movement of the rolled material between the roll buffer and the conveyor, and between the conveyor and the track guide vehicle, can occur when the rods mounted on the roll buffer, the conveyor, and the track guide vehicle are aligned with each other, and the pushing unit pushes the rolled material loaded through the rods of the hollow hub.

[0021] In a specific embodiment, the roll buffer may include a turntable disposed on the YZ plane and at least two or more rods disposed on the circumference of the turntable, and the turntable may rotate about a rotation axis passing through the center of the circumference in the X-axis direction, and due to the rotation of the turntable, the roll material loaded by the at least two or more rods on the turntable may be brought into access to the conveying device.

[0022] Here, multiple rolls of material can be loaded via at least two or more rods on a turntable.

[0023] Furthermore, the push unit provided in the roll buffer may include a pusher frame configured to move linearly in the Y-axis direction and a pusher configured to move linearly in the X-axis direction, the pusher being able to push the last portion of a plurality of rolls of material loaded by the at least two or more rods on the turntable so as to release one of the foremost rolls of material at a time.

[0024] Furthermore, in a specific embodiment, the conveying device may include: a base frame extending in the Y-axis direction; an intermediate frame configured to move linearly on the base frame in the Y-axis direction; a column configured to move linearly on the intermediate frame in the X-axis direction and extend in the Z-axis direction; and a conveying unit configured to move linearly on the column having a rod in the Z-axis direction, and a pushing unit configured to push the rear of the rolled material loaded through the rod of the hollow hub is mounted thereon.

[0025] Here, the conveying unit can linearly move at least the distance between the rod of the buffer and the rod of the track-guided vehicle in the Z-axis direction.

[0026] Furthermore, in a specific embodiment of the rail-guided vehicle, a pusher unit may be located at the rear of the rod of the rail-guided vehicle and pushes the rear of the rolled material loaded through the rod via the hollow hub.

[0027] In addition, the conveying unit may also include a slider of the conveying unit configured to move linearly together with the rod and the push unit. The rod of the conveying unit, which moves linearly due to the slider, may stop at the rod of the winding buffer or the rod of the track guide vehicle and be connected to the rod of the winding buffer or the rod of the track guide vehicle.

[0028] Meanwhile, in one embodiment, a chuck device configured to compress the inner surface of the hollow hub of the loaded coiled material can be disposed in the rod of the conveying unit.

[0029] In addition, the automated conveying and feeding equipment may also include a winding port disposed on the track of the conveying rail, the winding port having a rod capable of connecting to a rod of a track-guided vehicle.

[0030] In addition, the track-guided vehicle may also include a slider configured to move the rod of the track-guided vehicle and the push unit linearly together, the rod of the track-guided vehicle moving linearly due to the slider being able to stop at the rod at the winding machine port and be connected to the rod at the winding machine port.

[0031] In one embodiment, a chuck device configured to compress the inner surface of a hollow hub carrying rolled material can be disposed in the rod of a track-guided vehicle.

[0032] Here, the protruding step of the locking step that forms the hollow hub can be set on the end of the chuck device set in the rod of the track-guided vehicle.

[0033] [Beneficial Effects]

[0034] Using the automated conveying and feeding device of this invention, by loading large quantities of rolled material onto the roll buffer, sufficient time can be ensured until the material is exhausted on site, and the rolled material can be automatically supplied from the roll buffer to its destination in a rod-to-rod manner. Therefore, by applying the automated conveying and feeding device of this invention, operators of the winding equipment are freed from the arduous side task of simultaneously transporting rolled material, allowing them to focus more on their primary tasks, and significantly reducing the risk of damage to the rolled material during transport.

[0035] Furthermore, the automatic conveying and feeding equipment of the present invention also includes various components such as sliders and chuck devices. This improves the efficiency of conveying and feeding rolled materials in a rod-to-rod manner and ensures stable operation of the equipment.

[0036] The beneficial effects of the present invention are not limited to those described above. Those skilled in the art should clearly understand other unmentioned beneficial effects from the following detailed description. Attached Figure Description

[0049] Since the present invention can be modified in various ways and can have various implementations, specific implementations will be described in detail below.

[0050] However, this does not limit the invention to specific embodiments. All modifications, equivalents or alternatives included within the spirit and scope of the invention should be understood as belonging to the invention.

[0051] In this invention, terms such as “comprising” or “having” should be understood to specify the presence of features, numbers, steps, operations, elements, components or combinations thereof, without excluding the possibility of the presence or addition of one or more other features, numbers, steps, operations, elements, components or combinations thereof.

[0052] Furthermore, in this invention, when a portion such as a layer, film, region, or plate is described as being "on" another portion, this includes not only the case where the portion is "directly on" the other portion, but also the case where another portion exists between them. Conversely, when a portion, such as a layer, film, region, or plate, is described as being "below" another portion, this includes not only the case where the portion is "directly below" the other portion, but also the case where another portion exists between them. Additionally, in this application, being "disposed on" can include not only being disposed on an upper portion, but also being disposed on a lower portion.

[0053] This invention relates to an automatic conveying and feeding device for rolled materials.

[0054] In one embodiment, the automated conveying and feeding equipment for rolled materials includes a roll buffer, a conveying device, and an overhead lifting transport system (OHT).

[0055] The roll buffer receives rolled material loaded on a carriage in the X-axis direction and conveys the received rolled material in the YZ plane. Additionally, a conveyor receives rolled material from the roll buffer in the X-axis direction, moves the received rolled material onto the conveyor to a set position in the XY plane, and conveys the rolled material upwards in the Z-axis direction. In subsequent processes, a track-guided vehicle in the OHT receives the rolled material loaded onto the conveyor, which has already moved upwards in the Z-axis direction, and moves it along the trajectory of the conveyor track to its destination. Multiple track-guided vehicles can be configured.

[0056] In a specific embodiment, the wound material moves in a rod-to-rod manner between the winding buffer and the conveying device, and between the conveying device and the track-guided vehicle. A rod refers to a rod member configured to be inserted into a hollow hub of the wound material; the hollow hub, which can be mounted on the winding machine, is located at the center of the wound material. Considering that the wound material contains a hollow hub, and the winding machine contains rods corresponding to the hollow hubs, the present invention is configured such that a series of automated processes, including loading, releasing, conveying, and inputting the wound material, are performed in a rod-to-rod manner.

[0057] [Invention Method]

[0058] Hereinafter, specific embodiments of the automatic conveying and feeding equipment for rolled materials of the present invention (hereinafter referred to as "automatic conveying and feeding equipment") will be described with reference to the accompanying drawings.

[0059] Figure 1 This is a view showing the overall structure of the automatic conveying and feeding device 10 according to the present invention. In describing the invention, in order to clearly understand the invention, the same terms will be used to refer to elements having the same function, but different reference numerals will be used for elements referred to by the same term in order to clearly distinguish these elements.

[0060] refer to Figure 1 The automatic conveying and feeding device 10 of the present invention includes a roll buffer 100, a conveying device 200, and an overhead lift transport system (OHT) 300. As described above, in the present invention, the rolled material 30 moves in a rod-to-rod manner between the roll buffer 100 and the conveying device 200, and between the conveying device 200 and the track-guided vehicle 320. The rod-to-rod manner can be understood more clearly from the description of specific embodiments of each component.

[0061] Figure 2 This is a view illustrating the roll buffer 100 included in the present invention. The roll buffer 100 is a place for temporarily storing roll material 30, and the roll buffer 100 holds a certain amount of roll material 30, which is manually released from the warehouse using a carriage 20. In this way, the roll buffer 100 is used to prevent the roll material 30 used in the winding machine equipment from being exhausted in a short period of time.

[0062] The roll buffer 100 along the X-axis direction (based on...) Figure 1 The coordinate axis) receives the rolled material 30 loaded on the carriage 20 and transports the received rolled material 30 on the YZ plane.

[0063] exist Figure 2 In the specific embodiment shown, the roll buffer 100 includes a turntable 110 disposed on the YZ plane and at least two or more rods 120 disposed on the circumference of the turntable 110. In the X-axis direction, a large quantity of rolled material 30 brought in by the carriage 20 is loaded in a stack through each rod 120. In the example shown, four rods 120 are provided, and each rod 120 can hold a maximum of ten rolls of material 30. To ensure the roll buffer 100 effectively provides cushioning, as many rods 120 as possible can be provided.

[0064] Turntable 110 rotates about a rotation axis 112 that passes through the center of a circumference formed by a plurality of rods 120 in the X-axis direction, and the rolled material 30 loaded by the rods 120 approaches the conveyor 200 due to the rotation of turntable 110. That is, each rod 120 can approach the conveyor 200 sequentially by rotating turntable 110 (360° divided by the number of rods) by 90°, and after all the rolled material 30 loaded by one rod 120 has been released, turntable 110 is rotated to provide rolled material 30 loaded by subsequent rods 120 to the conveyor 200.

[0065] The method of using turntable 110 has several advantages, such as allowing multiple rods 120 to be set in a limited space, allowing the roll material 30 to be supplied sequentially and continuously by rotation, and allowing additional roll material 30 to be loaded through empty rods 120 before all the roll material 30 on turntable 110 is exhausted.

[0066] Figure 3 This is a view illustrating the conveying device 200 included in the present invention. The conveying device 200 receives rolled material 30 from the roll buffer 100 in the X-axis direction, moves to a set position in the XY plane with the received rolled material 30 loaded on the roll buffer 100, and conveys the rolled material 30 upward in the Z-axis direction. Figure 3 In the specific embodiment shown, the conveying device 200 includes a base frame 210, an intermediate frame 220, a column 230, and a conveying unit 240.

[0067] A base frame 210, placed on the floor surface, extends along the Y-axis, and an intermediate frame 220 moves linearly along the Y-axis on the base frame 210. The movement of the intermediate frame 220 in the Y-axis direction is achieved by a general configuration such as a linear motor and guide rails, and the lateral distance with the roll buffer 100 is adjusted by the movement of the intermediate frame 220 in the Y-axis direction (based on the figures).

[0068] The column 230 is a column member mounted on the intermediate frame 220 and extending in the Z-axis direction. The column 230 moves linearly in the X-axis direction on the intermediate frame 220. The movement of the column 230 in the X-axis direction is also achieved by a general configuration such as a linear motor and guide rails, and the longitudinal distance with the roll buffer 100 is adjusted by the movement of the column 230 in the X-axis direction (based on the figures).

[0069] Furthermore, a conveyor unit 240 configured to move linearly in the Z-axis direction is coupled to the column 230. The movement of the conveyor unit 240 is also achieved by a linear motor or the like, and a short rod 242 corresponding to the rod 120 of the roll buffer 100 is provided inside the conveyor unit 240, which moves in the height direction.

[0070] Multiple linear movements occur from the intermediate frame 220 to the conveying unit 240, ultimately achieving three-axis movement in the X, Y, and Z directions. In this way, the conveying unit 240 can be positioned at any position in the three-dimensional coordinate system within the range of motion.

[0071] Figure 4 It is shown Figure 2 Volume buffer 100 and Figure 3 A view showing the arrangement of the conveyor 200. Figure 5 This is a front view of the arrangement of the roll buffer 100 and the conveyor 200. The rod 120 in the roll buffer 100 is located within the rotation radius of the turntable 110, and due to the three-axis motion, the conveying unit 240 of the conveyor can approach the rolled material 30 loaded on the roll buffer 100. Of course, the longitudinal and lateral spacing between the roll buffer 100 and the conveyor 200 is within the range of movement of the conveying unit 240 in the XY plane.

[0072] As described above, in the automatic conveying and feeding device 10 of the present invention, the rolled material 30 moves between the roll buffer 100 and the conveying device 200 in a rod-to-rod manner. That is, the rod 120 provided in the roll buffer 100 and the rod 242 provided in the conveying device 200 are coaxially aligned with each other, and the rolled material 30 moves from the roll buffer 100 to the conveying unit 240 of the conveying device 200 via the aligned rods 120 and 242. Here, the present invention includes pushing units 130, 246, and 326 configured to provide a force allowing the rolled material 30 to move.

[0073] Figure 6 This is a view showing the rod-to-rod conveying of the rolled material 30 between the roll buffer 100 and the conveyor 200. When the rolled material 30 is conveyed between the roll buffer 100 and the conveyor 200 in a rod-to-rod manner, the push unit 130 provided in the roll buffer 100 moves the rolled material 30 because the rolled material 30 is loaded in the roll buffer 100.

[0074] Figure 2 The push unit 130 disposed in the roll buffer 100 is clearly shown in the figure. Referring to this figure, the push unit 130 of the roll buffer 100 includes a pusher frame 132 and a pusher 134. The pusher frame 132 is configured to move linearly in the Y-axis direction, and the pusher 134 is configured to move linearly on the pusher frame 132 in the X-axis direction. The pusher frame 132 adjusts the distance between the push unit 130 and the rod 120. That is, the pusher frame 132 moves backward in the negative Y-axis direction to prevent interference during the rotation of the turntable 110, and moves forward in the Y-axis direction to bring the pusher 134 closer to the roll material 30 during the release of the roll material 30. In this way, the distance is adjusted.

[0075] refer to Figure 6 The pusher unit 130 is positioned close to the rod 120 of the turntable 110, and the pusher 134 pushes the last portion of the multiple rolls of material 30 loaded on the rod 120 on the turntable 110 to release one of the foremost rolls of material 30 at a time. Here, the rod 242 mounted on the conveyor unit 240 at the end of the forming conveyor 200 is aligned so that the three-dimensional position of the rod 242 is coaxial with the rod 120, and the pusher 134 of the roll buffer 100 operates relative to the rod 120. Therefore, the foremost roll of material 30 pushed out by the pusher 134 of the roll buffer 100 moves to the rod 242 of the conveyor unit 240.

[0076] The conveying unit 240 of the conveying device 200 that receives the rolled material 30 loaded in the roll buffer 100 moves so that the three-dimensional position of the conveying unit 240 moves toward the track guide vehicle 320 of the OHT 300, that is, moves upward along the column 230.

[0077] Figure 7 This is a view showing a track-guided vehicle 320. The track-guided vehicle 320 shown is an automated electric vehicle configured to move along a track 310 mounted on the ceiling to a set or input destination, and the track-guided vehicle 320 is provided with a handling device that can receive materials from the starting point and deliver the received materials to the destination.

[0078] Rod 322 and push unit 326 are provided as material handling devices in the track-guided vehicle 320 of the present invention. Figure 7 The image shows the state of the coiled material 30 loaded via rod 322. Here, the image also illustrates... Figure 7 The vehicle body frame, drive unit, etc. are set in the track-guided vehicle 320, but since these configurations are known components, their detailed descriptions will be omitted.

[0079] refer to Figure 1 The track-guided vehicle 320 receives the rolled material 30 loaded on the conveying unit 240 of the conveying device 200, which has been moving upward in the Z-axis direction, and moves it to the destination along the track 310. Although omitted in the figures, the conveying track constitutes a circular trajectory starting from the conveying device 200 as the starting point, passing through the destination (such as a winding machine) and returning to the conveying device 200.

[0080] Figure 8This is a view showing the rod-to-rod transport of rolled material 30 between the conveyor 200 and the track guide vehicle 320. Because the conveyor unit 240 of the conveyor 200 releases the rolled material 30 from the roll buffer 100 disposed below the conveyor unit 240 and transports the rolled material 30 to the track guide vehicle 320 disposed above the conveyor unit 240, the conveyor unit 240 may be able to linearly move at least the distance (height) between the rod 120 of the roll buffer 100 and the rod 322 of the track guide vehicle 320 in the Z-axis direction.

[0081] refer to Figure 8 The conveying of rolled material 30 between the conveyor 200 and the track-guided vehicle 320 in a rod-to-rod manner is conceptually equivalent to... Figure 6 The rolled material 30 is conveyed in a rod-to-rod manner between the roll buffer 100 and the conveyor 200. Figure 8 In the transport and Figure 6 The only difference in the conveying process is that, since the rolled material 30 is loaded on the conveying unit 240, the pushing unit 246 provided in the conveying unit 240 is operated.

[0082] The conveying unit 240, moving upward in the Z-axis direction, moves to a set point in the XYZ coordinate system, making the rod 242 of the conveying unit 240, which loads the roll material 30, coaxial with the rod 322 of the track guide vehicle 320. The pushing unit 246 of the conveying unit 240 pushes the rear of the roll material 30 with the two rods 242 and 322 aligned with each other, conveying the roll material 30 between the conveying device 200 and the track guide vehicle 320 in a rod-to-rod manner.

[0083] As described above, by using the automatic conveying and feeding device 10 of the present invention, by loading a large amount of roll material 30 onto the roll buffer 100, sufficient time can be ensured until the material is exhausted on site, and the roll material 30 can be automatically supplied from the roll buffer 100 to the destination in a rod-to-rod manner.

[0084] Therefore, by applying the automatic conveying and feeding device 10 of the present invention, the operator of the winding machine can be freed from the heavy side task of transporting the coiled material 30 at the same time, thus allowing him to concentrate more on the main task and greatly reducing the risk of damage to the coiled material 30 during the movement of the coiled material 30.

[0085] Figure 8 This is a view showing the rod-to-rod conveying of rolled material 30 between the conveyor 200 and the track-guided vehicle 320. (View) Figure 8As shown in the right figure, the conveying unit 240 of the conveying device 200 may also include a slider 248, which is configured to cause the rod 242 and the push unit 246 to move linearly together.

[0086] The rod 242 of the conveying unit 240, which moves linearly due to the slider 248, can stop at and connect with the rod 120 of the roll buffer 100 and the rod 322 of the track guide vehicle 320. After the rod 242 stops, the push unit 246 moves the roll material 30, and after the conveying of the roll material 30 is completed, the slider 248 moves the rod 242 and the push unit 246 back to their original positions.

[0087] Thus, when conveying the coiled material 30 in a rod-to-rod manner, in addition to simply making the opposing rods 242 and 322 coaxial with each other, the slider 248 also connects the rods 242 and 322 so that they form a single axis. In this way, the slider 248 ensures that the coiled material 30 moves stably without being caught in the middle or falling off.

[0088] In particular, since the rod-to-rod conveying of the rolled material 30 between the conveying unit 240 and the track-guided vehicle 320 is carried out at a height, it is difficult to resolve problems when the movement of the rolled material 30 malfunctions, and there is a high concern about accidents caused by the rolled material 30 falling. Furthermore, since the slider 248 significantly extends the effective length of the rod 242, the additional effect of reducing the risk of accidental interference or collisions can be achieved by shortening the rod 242 of the conveying unit 240 that performs the three-dimensional motion.

[0089] Figure 9 This is a view showing the configuration of the pusher unit 326 and slider 328 provided in the track guide vehicle 320. The slider 328 provided in the track guide vehicle 320 also causes the rod 322 and the pusher unit 326 to move linearly together. The addition of the slider 328 to the configuration of the track guide vehicle 320 is a result of providing a winding machine port 400 as a docking system in various winding devices (not shown) for handling the rolled material 30.

[0090] Figure 10 The diagram shows a winding machine port 400, which corresponds to the destination of receiving the coiled material 30 transported by the track-guided vehicle 320. A rod 410 corresponding to the hollow hub 32 of the coiled material 30 is provided in the winding machine port 400. Here, the configuration (not shown) for mounting the coiled material 30 received at the winding machine port 400 onto the winding machine equipment is beyond the scope of this invention and will therefore be omitted from description.

[0091] Figure 10 This is a view showing the rod-to-rod conveying of rolled material 30 between the track-guided vehicle 320 and the winding machine port 400. In this invention, for the rod-to-rod conveying of rolled material 30, equivalent structures and methods are always maintained, and the rod 410 of the winding machine port 400, which matches the movement trajectory of the track-guided vehicle 320, is in a direction and height that allows the rod 410 to be coaxial with the rod 322 of the track-guided vehicle 320.

[0092] like Figure 9 As shown, the track-guided vehicle 320 also includes a slider 328 configured to cause the rod 322 and the push unit 326 to move linearly together. Furthermore, as... Figure 10 As shown, the rod 322 of the track guide vehicle 320, which moves linearly due to the slider 328, can stop at and connect to the rod 410 of the winding machine port 400. After the rod 322 stops, the push unit 326 pushes the wound material 30 and moves the wound material 30 to the rod 410 of the winding machine port 400. Furthermore, after the conveying of the wound material 30 is completed, the slider 328 moves the rod 322 and the push unit 326 back to their original positions.

[0093] Additionally, an auxiliary device may be provided for stably maintaining the movement of the coiled material 30 occurring at a height. This device is chuck devices 244 and 324, and references known devices in which a plurality of radially moving jaws secure members are used. In an exemplary embodiment of the invention, a universal chuck with three electrically or pneumatically operated jaws is used.

[0094] Figure 11 This is a view showing a chuck device 244 disposed in the rod 242 of the conveying unit 240 of the conveying device 200. The chuck device 244 shown is an example in which the rod 242 is formed as a hollow structure and three jaws are disposed in the space of the rod 242. The chuck device 244 disposed in the rod 242 of the conveying unit 240 presses against the inner surface of the hollow hub 32 of the rolled material 30, thereby firmly fixing the rolled material 30 to the rod 242. The fixed state of the rolled material 30, secured by the chuck device 244, remains stable even during the three-dimensional movement of the conveying unit 240.

[0095] Figure 12 This is a view showing the chuck device 324 disposed in the rod 322 of the track-guided vehicle 320. The chuck device 324 of the track-guided vehicle 320 has a structure substantially equivalent to that of the chuck device 244 of the conveyor 200, and three jaws press against the inner surface of the hollow hub 32 of the rolled material 30.

[0096] However, since the track-guided vehicle 320 is frequently subjected to various inertial forces, such as acceleration, braking, and centrifugal force, while moving along the trajectory of the transport track 310 and traveling in curved tracks, the rolled material 30 can be secured more reliably. To this end, the chuck device 324 of the track-guided vehicle 320 has a protruding step 325 at its end to form a locking step for the hollow hub 32. By constraining the hollow hub 322 from falling outwards towards the rod 322 through the protruding step 325, the secured state of the rolled material 30 is reliably maintained even when the track-guided vehicle 320 travels in complex tracks.

[0097] The present invention has been described in detail above using the accompanying drawings and embodiments. However, the configurations illustrated or described in the drawings or embodiments are only some embodiments of the present invention and do not represent the full technical essence of the present invention. Therefore, it should be understood that various equivalent methods and modifications that can replace the corresponding configurations may exist at the time of filing this application.
