Description
[0001] Cross - reference to related applications
[0002] This application claims the priority of Korean Patent Application No. 10 - 2023 - 0184821, filed with the Korean Intellectual Property Office on December 18, 2023, and all rights derived therefrom under 35 U.S.C. 119, the entire contents of which are incorporated herein by reference. Technical field
[0003] The present disclosure relates to a roll transfer device and method. Background art
[0004] A secondary battery is a battery that can be reused through discharging, which converts chemical energy into electrical energy, and charging, which converts electrical energy into chemical energy.
[0005] Examples of secondary batteries include nickel - cadmium batteries, nickel - hydrogen batteries, lithium - ion batteries, or lithium - ion polymer batteries.
[0006] Such a secondary battery includes a negative electrode, a positive electrode, an electrolyte, and a separator, and stores and generates electricity by utilizing the voltage difference between different negative and positive electrode materials.
[0007] Among methods for manufacturing secondary batteries, a method for manufacturing a lithium - ion secondary battery includes: stacking a first separator, an anode plate, a second separator, and an anode plate; winding them multiple times to form an electrode assembly; sealing the electrode assembly in a case; and injecting an electrolyte into the case.
[0008] In this case, the separator is provided and supplied in the form of a wound roll, and this separator cannot increase its diameter due to material characteristics, so the roll should be frequently replaced during the winding process.
[0009] In this way, in order to replace the roll, when storing the roll wound with the separator, workers classify the rolls according to the type of the corresponding separator and supply the classified rolls to the manufacturing equipment.
[0010] Meanwhile, the position and center of the roll installed on the manufacturing equipment should be accurately identified so that the defect rate of the product can be reduced.
[0011] In this manner, in order to accurately match the position and center of the cylinder, a centering work is performed by directly pressing the roll core on both sides of the cylinder with the same force using a cylinder. Due to the heavy load of the cylinder and the friction with the roll core, it is difficult to perform the centering work by pressing the roll core, and the centering work may not be performed, thereby possibly reducing the reliability of the centering work. Summary of the Invention
[0012] An object of the present disclosure is to provide a cylinder transfer device and method that facilitate centering work on a cylinder stored in a left eccentric state or a right eccentric state to improve the reliability of the cylinder centering work.
[0013] The object of the present disclosure is not limited to the above object, and other objects of the present disclosure not mentioned herein will be clearly understood by those skilled in the art from the following description of the present disclosure.
[0014] According to an aspect of the present disclosure, a cylinder transfer device designed to achieve the above object includes: a plurality of frame units that constitute an external appearance; a pair of holding units that are spaced apart from each other in a first direction inside the frame unit and support a roll core seated on the pair of holding units; a pair of lifting units that are provided on two upper sides in the first direction inside the frame unit to lift the cylinder in a second direction and are connected to each other by a first plate; a pair of alignment units that are provided on the first plate and are provided on both sides in the first direction to align the position of the cylinder in the first direction; and a pair of transfer units that transfer a cylinder with a roll core seated on the pair of holding units in a third direction by simultaneously moving the pair of holding units in the third direction, wherein the pair of alignment units linearly move with different strokes in the first direction to align in the first direction when the cylinder with a roll core seated on the pair of holding units is eccentric in the first direction.
[0015] According to another aspect of the present disclosure, a cartridge transfer device designed to achieve the above object includes: a plurality of holding units spaced apart from each other in a first direction and supporting a cartridge core portion disposed on the plurality of holding units; a pair of lifting units provided on two upper sides in the first direction to lift the drum in a second direction and connected to each other by a connection plate; a pair of alignment units provided on the connection plate and disposed on both sides in the first direction to align the positions of the cartridges in the first direction; and a pair of transfer units that transfer the cartridge having the cartridge core portion disposed on the holding unit pair in a third direction by simultaneously moving the holding unit pair in the third direction, wherein the alignment unit includes: a pair of linear motion LM guides spaced apart from each other in the third direction on the connection plate and extending in the first direction; a moving plate coupled to the pair of linear motion LM guides by one or more linear motion LM blocks to linearly move in the first direction; a pair of support blocks provided adjacent to the linear motion LM guides on the connection plate and spaced apart from each other in the first direction; a rotating shaft connecting the pair of support blocks; a driving motor connected to the rotating shaft through a coupler on the connection plate to transmit a driving force to the rotating shaft; a carrier disposed on the rotating shaft and coupled to the lower surface of the moving plate; an extension frame disposed on the lower surface of the moving plate and extending downward through an opening formed at a position spaced apart from each other by the pair of linear motion LM guides in the connection plate; a hand block disposed in the extension frame and inserted into the cartridge core portion disposed on the upper portion of the holding unit; and an inner diameter detection sensor disposed inside the hand block to detect the inner diameter of the cartridge core portion. When the cartridge core portion is disposed on the holding unit pair, the moving plate linearly moves in the first direction by driving of the driving motor, and at the same time, the extension frame and the hand block linearly move in the first direction to insert the hand block into the cartridge core portion. When the inner diameter detection sensor detects the inner diameter of the cartridge core portion, the driving of the driving motor is stopped to stop the insertion of the hand block. In a state where the hand block is inserted into the cartridge core portion, the cartridge is lifted by the pair of lifting units. In a state where the cartridge is eccentric in the first direction, the distances from the starting positions of each of the cartridge core portions on both sides in the first direction to the position where the inner diameter detection sensor detects the inner diameter of the cartridge core portion are calculated, so that the driving motors of each of the pair of alignment units are driven with different strokes. The fifth plate, the extension frame, and the hand block of each of the pair of alignment units move in the first direction with different strokes together with the cartridge in the first direction to align the cartridge eccentric in the first direction in the first direction.
[0016] According to one aspect of the present disclosure, a cylinder transfer method designed to achieve the above object includes: placing a cylinder core part at a position between holding unit pairs by an unmanned transport vehicle or a forklift, the holding unit pairs being spaced apart from each other in a first direction and facing each other; inserting a hand block of each of a pair of alignment units provided on both sides of the cylinder core part into the cylinder core part at both sides of the cylinder in the first direction; in a state where the hand blocks are inserted into the cylinder core part, lifting the cylinder in a second direction by a pair of lifting units spaced apart from each other in the first direction; aligning the cylinder in the first direction by driving each of the pair of alignment units with different scrolls to correspond to an initial position of each of the cylinder core parts on both sides of the eccentric cylinder in the first direction; lowering the cylinder aligned in the first direction in the second direction by lowering the pair of lifting units in the second direction to place the cylinder core part on the holding unit pairs again; when rotating the cylinder core part by rotating any one of a pair of seating rollers provided in the holding unit pairs for placing the cylinder thereon, identifying a unique identification number of a material to be wound on the cylinder by a barcode reader; and moving the cylinder in a third direction by moving the holding unit pairs in the third direction by moving a pair of transfer units in the third direction, the holding unit pairs being respectively provided in the pair of transfer units, and the cylinder being placed on the holding unit pairs.
[0017] Details of other embodiments are included in the detailed description and the drawings.
[0018] In a cylinder transfer device and method according to some embodiments of the present disclosure, in a state where a cylinder stored in a left-eccentric or right-eccentric state is lifted by a lifting unit to minimize friction, instead of pressing the cylinder core part with the same force from both the left and right sides, by calculating a distance detected by an inner diameter detection sensor from an initial position of storing the cylinder core part, alignment units on both the left and right sides move in a left-right direction with different strokes together with the cylinder to align the cylinder, thereby simplifying the centering operation and improving the position accuracy during the transfer operation to enhance the reliability of the cylinder centering operation.
[0019] The effects of the embodiments according to the present disclosure are not limited to the above effects, and more different effects are included in the following description of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The advantages and features of the present disclosure, as well as the methods for achieving these advantages and features, will become apparent from the following more detailed description of the embodiments with reference to the accompanying drawings.

In the drawings, the embodiments of the present disclosure are defined by the scope of the claims. Throughout the specification, the same reference numerals denote the same elements.
[0031] The terms used in this document are for the purpose of embodiments only and are not intended to limit the present disclosure. In the present disclosure, unless otherwise mentioned, the singular forms are intended to include the plural forms. The terms "comprises" and / or "comprising" used in this document specifically refer to the existence of the described elements, steps, operations, and / or objects, but do not exclude the existence or addition of one or more other elements, steps, operations, and / or objects.
[0032] Figure 1 is a schematic perspective view of a cylinder of a cylinder transfer device according to some embodiments of the present disclosure. Figure 2 is a schematic perspective view of a cylinder transfer device according to some embodiments of the present disclosure.
[0033] Referring to Figure 1 and Figure 2 According to some embodiments of the present disclosure, the cylinder transfer device 100 may include a frame unit 110, a holding unit 120, a lifting unit 130, an alignment unit 140, and a transfer unit 150.
[0034] According to some embodiments of the present disclosure, a plurality of frame units 110 may be arranged along a first direction D1, a second direction D2, and a third direction D3 to form the outer shape of the cylinder transfer device 100.
[0035] The frame unit 110 may have a shape that is open forward and backward along the third direction D3. That is, the stored cylinder 10 is transferred along the third direction D3 from the front by an automatic guided vehicle (AGV) or a forklift, and then transferred to the stacker crane at the back.
[0036] The frame unit 110 may include a third plate 111.
[0037] The third plate 111 may be disposed inside the frame unit 110 for the arrangement of the lifting unit 130. The third plate 111 may be disposed above both sides of the frame unit 110 along the first direction D1 and the second direction D2. The third plate 111 may be provided with a first linear motion LM guide pair 132 of the lifting unit 130.
[0038] Figure 3 is a schematic partial perspective view of the holding unit and the transfer unit of a cylinder transfer device according to some embodiments of the present disclosure. Figure 4 is a schematic partial perspective view of the holding unit of a cylinder transfer device according to some embodiments of the present disclosure.
[0039] The holding units 120 may be disposed inside the plurality of frame units 110. The holding units 120 may be disposed in pairs at intervals in the first direction D1. The holding units 120 may have the shape of supporting the core part 11 mounted thereon.
[0040] The holding unit 120 may include a second plate 121, a mounting roller 122, and a first drive motor 124.
[0041] The second plates 121 may be disposed in pairs at intervals in the first direction D1. The second plates 121 may have the shape of supporting the mounting roller 122 mounted therein. The second plates 121 may rotatably support the mounting roller 122.
[0042] The shaft 123 of the mounting roller 122 may pass through and be coupled to the pair of second plates 121. The pair of second plates 121 may be disposed on the workbench 151.
[0043] The pair of second plates 121 may move in the third direction D3 when disposed on the workbench 151. In this case, the third direction D3 may be a direction orthogonal to the first direction D1 on the plane.
[0044] The mounting roller 122 may be rotatably coupled to the second plate 121 through the shaft 123. The mounting rollers 122 may be disposed in pairs adjacent to each other or in surface contact with each other in the third direction D3.
[0045] The mounting roller 122 may rotate. The pair of mounting rollers 122 may rotate respectively. The core part 11 mounted on the mounting roller 122 may rotate by the rotation of the pair of mounting rollers 122.
[0046] Any one of the pair of mounting rollers 122 may rotate. Since the pair of mounting rollers 122 are disposed adjacent to each other or in surface contact with each other, the rotation of any one of the pair of mounting rollers 122 causes the other one to also rotate.
[0047] In the case where the core part 11 is rotated by the rotation of any one of the pair of mounting rollers 122, the other mounting roller 122 may also rotate. The pair of mounting rollers 122 may support the rotation of the core part 11.
[0048] The first drive motor 124 may be disposed on the workbench 151. The first drive motor 124 may be connected to the mounting roller 122.
[0049] The first drive motor 124 is arranged to rotate the mounting roller 122. The first drive motor 124 may be connected to the controller. The first drive motor 124 may be actuated by the controller to rotate the mounting roller 122. The first drive motor 124 may be connected to the shaft 123 of any one of the pair of mounting rollers 122 to rotate the mounting roller 122.
[0050] The first drive motor 124 can be connected to the shaft 123 of the mounting roller 122 via a drive pulley 125 and a timing belt 126. The drive pulley 125 and the timing belt 126 can transmit the driving force from the first drive motor 124 to the shaft 123 of the mounting roller 122 to rotate the mounting roller 122.
[0051] The bobbin transfer device 100 according to some embodiments of the present disclosure may further include a seating detection sensor. The holding unit 120 may include a seating detection sensor.
[0052] The seating detection sensor can detect the seating of the bobbin core portion 11. That is, the seating detection sensor can detect that the bobbin core portion 11 of the bobbin 10 stored in the bobbin transfer device 100 is seated on the mounting roller pair 122 by means of an unmanned transport vehicle or a forklift, etc.
[0053] In addition, the seating detection sensor can detect that the bobbin 10 positioned in the first direction D1 aligned by the alignment unit 140 is lowered by the lifting unit 130 and then seated on the mounting roller pair 122.
[0054] The seating detection sensor can transmit a signal for detecting that the bobbin core portion 11 has been seated to the controller. The seating detection sensor can have a shape provided on the second plate 121 or the mounting roller 122.
[0055] The holding unit 120 can move along the third direction D3 on the workbench 130 of the transfer unit 150. Therefore, the bobbin 10 on which the unique identification number of the material wound around the bobbin 10 is identified can be transferred to the stacker crane.
[0056] The bobbin transfer device 100 according to some embodiments of the present disclosure may further include a barcode reader. The barcode reader can identify the unique identification coating for the material wound around the bobbin 10. The barcode reader can be connected to the controller. The barcode reader can have a shape provided on the frame unit 110 or the workbench 151. The barcode reader can be provided above the holding unit 120.
[0057] The barcode reader can identify the unique identification number at a specific position by means of the bobbin 10 rotating according to the rotation of the mounting roller pair 122. That is, in a state where the position of the bobbin 10 in the first direction 10 is aligned by the alignment unit 140, the bobbin 10 also rotates due to the rotation of the bobbin core portion 11 rotating according to the rotation of the mounting roller pair 122, so that the barcode reader can uniformly identify the unique identification number at a specific position.
[0058] This enables the unique identification code of the material wound around the bobbin 10 to be conveniently identified even when the bobbin 10 carried and stored in the bobbin transfer device 100 is not stored in place.
[0059] In this way, the barcode reader can identify the unique identification code of the bobbin 10 in a state where the bobbin 10 is aligned along the first direction D1 and even in a state where the bobbin 10 is not aligned along the first direction 10.
[0060] Figure 5 and 6 are schematic partial perspective views showing the lifting unit and the alignment unit of the bobbin transfer device according to some embodiments of the present disclosure. Figure 7 is a schematic perspective view showing the lifting unit of the bobbin transfer device according to some embodiments of the present disclosure.
[0061] The lifting unit 130 may be provided in the upper part inside the frame unit 110. The lifting unit 130 may be provided to be spaced apart from another lifting unit inside the frame unit 110 along the first direction D1. The lifting unit 130 may be provided in pairs on the two upper sides inside the frame unit 120 along the first direction D1 and the second direction D2.
[0062] The pair of lifting units 130 may be connected to each other by a first plate 131 (connection plate). In this case, the first plate 131 (connection plate) may include an opening H formed at a position where the second linear motion LM guide rails 141 of the alignment unit 140 are spaced apart from each other. The extension frame 149 of the alignment unit 140 may extend downward through the opening H formed in the first plate 131 (connection plate).
[0063] The pair of lifting units 130 may lift and lower the bobbin 10 in which the bobbin core portion 11 is mounted on the pair of holding units 120.

[0065] The first linear motion LM guide rail 132 may be provided on a third plate 111, and the third plate is provided on the two upper sides inside the plurality of frame units 110 along the first direction D1 and the second direction D2. The first linear motion LM guide rails 132 may be provided in pairs and spaced apart from each other along the third direction D3. The first linear motion LM guide rail 132 may have a shape extending along the second direction D2.
[0066] The fourth plate 134 may be disposed on the first linear motion LM guide rail 132. The fourth plate 134 may be arranged to be linearly movable along the second direction D2. The fourth plate 134 may be coupled to the first linear motion LM guide rail 132 by one or more first linear motion LM blocks 133.
[0067] The second drive motor 135 may be disposed on the fourth plate 134. The second drive motor 135 may raise and lower the fourth plate 134. The second drive motor 135 may be connected to the controller.
[0068] The second drive motor 135 may raise and lower the fourth plate 134 in a state where the hand block B of the alignment unit 140 is inserted into the core part 11. The second drive motor 135 may be used as a power source for raising and lowering the cylinder 10.
[0069] The lifting unit pair 130, the first plate 131 (connecting plate) connecting the lifting units, and the alignment unit 140 may be lifted integrally by the actuation of the second drive motor 135.
[0070] The second drive motor 135 may include a first pinion 136 disposed outside the fourth plate 134 along the first direction D1.
[0071] The first rack 137 may be disposed outside the fourth plate 134 along the first direction D1. The first rack 137 may have a shape extending along the second direction D2.
[0072] By actuating the second drive motor 135 by the controller, the first rack 137 may engage with the first pinion 136 to form a gear meshing.
[0073] The fourth plate 134 may be raised and lowered by the gear meshing of the first rack 137 and the first pinion 136. The fourth plate 134 may be raised and lowered in a state where the hand block B is inserted into the core part 11 by the gear meshing of the first rack 137 and the first pinion 135.
[0074] In this way, the lifting of the cylinder 10 in which the fourth plate 134 is lifted by the actuation of the second drive motor 135 may be restricted by a dog sensor. The dog sensor may be connected to the controller.
[0075] Figure 8 It is a schematic perspective view showing an alignment unit of a cylinder transfer device according to some embodiments of the present disclosure.
[0076] Refer to Figure 5 、 Figure 6 and Figure 8, the alignment unit 140 may be provided on the first plate 131 (connection plate). The alignment unit 140 may be provided in pairs on both sides along the first direction D1. The alignment unit 140 aligns the position of the cylinder 10 along the first direction D1.
[0077] The pair of alignment units 140 may linearly move with different strokes along the first direction D1, such that the pair of alignment units 140 may store in an eccentric state along the first direction D1, so that the cylinder 10 with the cylinder core portion 11 disposed on the pair of holding units 120 is aligned along the first direction D1.
[0078] The alignment unit 140 may include a second linear motion LM guide rail 141, a fifth plate 143 (moving plate), a support block 144, a rotating shaft 145, a third drive motor 146, a carrier 148, an extension frame 149, a hand block B, and an inner diameter detection sensor S.
[0079] The second linear motion LM guide rail 141 may be provided on the first plate 131 (connection plate). The second linear motion LM guide rails 141 may be provided in pairs and spaced apart from each other along the third direction D3. The second linear motion LM guide rails 141 may have a shape extending along the first direction D1.
[0080] The fifth plate 143 (moving plate) may be coupled to the second linear motion LM guide rail 141. The fifth plate 143 (moving plate) may be coupled to one or more second linear motion LM blocks 142. One or more second linear motion LM blocks 142 may be coupled to the second linear motion LM guide rail 141. The fifth plate 143 (moving plate) may be arranged to be linearly movable along the first direction D1.
[0081] The support block 144 may be fixed on the first plate 131 (connection plate). The support block 144 may be arranged adjacent to the second linear motion LM guide rail 141. The support blocks 144 may be arranged in pairs and spaced apart from each other along the first direction D1.
[0082] Bearings are provided inside the pair of support blocks 144. One end and the other end of the rotating shaft 145 in the first direction D1 are respectively rotatably mounted on the bearings provided in the pair of support blocks 144. The pair of bearings fixes the rotating shaft 145 to a non-eccentric position. The pair of bearings supports the weight of the rotating rotating shaft 145 and the load applied to the rotating shaft 145.
[0083] The rotating shaft 145 connects the pair of support blocks 144 in the first direction D1. The rotating shaft 145 may move the carrier 148 along the first direction D1 by the driving force transmitted by the third drive motor 146.
[0084] The rotating shaft 145 may have a ball screw shape. The rotating shaft 145 may convert the rotational movement of the third driving motor 146 into a linear movement of the carrier 148 disposed on the rotating shaft 145. The rotating shaft 145 may be rotated by the third driving motor 146 to linearly move the carrier 148 in the first direction D1 on one side or the other side in the first direction D1 toward the support block 144 on one side or the support block 144 on the other side.
[0085] The third driving motor 146 may be fixed to the first plate 131 (connection plate). The third driving motor 146 is connected to either one of the pair of support blocks 144 to transmit a driving force to the rotating shaft 145.
[0086] The third driving motor 146 is connected to the rotating shaft 145 through a coupler 147. Even if the concentricity (concentric axis) of the rotating shaft 145 is offset during the movement of the carrier 148, the coupler 147 may hold the rotating shaft 145 and rotate the rotating shaft 145 in a specific axial direction.
[0087] The third driving motor 146 generates a rotational force and transmits the driving force to the rotating shaft 145 having a ball screw shape. The third driving motor 146 may be connected to a controller. The controller may actuate the third driving motor 146.
[0088] The carrier 148 may be coupled to the lower surface of the fifth plate 143 (moving plate). The carrier 148 may be disposed on the rotating shaft 145 and may linearly move in the first direction D1 by the driving force transmitted by the third driving motor 146. The fifth plate 143 (moving plate) may linearly move in the first direction D1 in a state where the fifth plate 143 (moving plate) is disposed on the second linear motion LM guide 141 by the linear movement of the carrier 148.
[0089] The extension frame 149 may be fixed to the lower surface of the fifth plate 143 (moving plate). The extension frame 149 may be disposed at a position spaced apart from the lower surface of the fifth plate 143 (moving plate) by the second linear motion LM guide pair 141. The extension frame 149 may have a shape extending downward through the opening H of the first plate 131 (connection plate).
[0090] The hand block B may be disposed on the extension frame 149. The hand block B may be disposed at the lower end of the extension frame 149. The hand block B may be inserted into the core portion 11 provided on the upper portion of the holding unit 120 by the actuation of the third driving motor 146. The hand block B may be inserted into the core portion 11 provided on the pair of mounting rollers 122.
[0091] The inner diameter detection sensor S can be disposed inside the hand block B. The inner diameter detection sensor S can detect the inner diameter of the core part 11 during the process of inserting the hand block B into the core part 11. The inner diameter detection sensor S can be connected to the controller.
[0092] That is, when the core part 11 is installed on the pair of holding units 120 facing each other along the first direction D1, the fifth plate 143 (moving plate) can linearly move along the first direction D1 by the drive of the third drive motor 146. At the same time, the extension frame 149 and the hand block B can also linearly move along the first direction D1 integrally with the fifth plate 143 (moving plate), so that the hand block B can be inserted into the core part 11.
[0093] When the hand block B is inserted into the position where the inner diameter detection sensor S can detect the inner diameter of the core part 11, the controller can receive the inner diameter detection signal of the core part 11 from the inner diameter detection sensor S, and stop the drive of the third drive motor 146 to stop the insertion of the hand block B.
[0094] The controller raises and lowers the cylinder 10 by actuating the pair of lifting units 130 in a state where the hand block B is inserted into the core part 11.
[0095] The controller calculates the distances from the initial positions of each of the two sides of the core part 11 in the first direction D1 to the position where the inner diameter detection sensor S detects the inner diameter of the core part 11 in a state where the cylinder 10 is eccentric in the first direction D1.

[0100] Reference Figure 3 and Figure 9 The transfer units 150 may be provided in pairs spaced apart from each other in the first direction D1 to simultaneously move the holding unit pair 120 in the third direction D3.
[0101] The pair of transfer units 150 may transfer the cylinder 10 in the third direction D3, in which the core portion 11 of the cylinder is mounted on the pair of holding units 120 on both sides in the first direction D1.
[0102] Each of the pair of transfer units 150 may include a workbench 151, a mounting frame 152, a third linear motion LM guide 153, a sixth plate 155, a fourth drive motor 156, a second pinion 157, and a second rack 158.
[0103] The workbenches 151 may be provided in pairs spaced apart from each other in the first direction D1. The workbenches 151 may have a shape extending in the third direction D3. The pair of holding units 120 may be respectively provided on the upper surfaces of the pair of workbenches 151.
[0104] The mounting frames 152 may be provided in pairs spaced apart from each other in the first direction D1 on the upper surfaces of the workbenches 151. The mounting frames 152 may have a shape extending in the third direction D3.
[0105] The third linear motion LM guides 153 may be provided on the upper surfaces of each of the pair of mounting frames 152. The third linear motion LM guides 153 may have a shape extending in the third direction D3.
[0106] The sixth plate 155 may be provided on the third linear motion LM guide 153. The sixth plate 155 may be provided to be linearly movable in the third direction D3. The sixth plate 155 may be coupled to the third linear motion LM guide 153 through one or more third linear motion LM blocks 154. The holding unit 120 may be provided on the upper surface of the sixth plate 155.
[0107] The fourth drive motor 156 may be provided on the sixth plate 155. The fourth drive motor 156 may linearly move the sixth plate 155 in the third direction D3. The fourth drive motor 156 may be connected to the controller.
[0108] The fourth drive motor 156 may move the sixth plate 155 in the third direction D3 in a state where the core portion 11 of the cylinder is mounted on the pair of mounting rollers 122. The fourth drive motor 156 may have a shape serving as a power source for transferring the cylinder 10 to the stacker crane.
[0109] The holding unit pair 120 and the cylinder 10 disposed on the holding unit pair 120 can be integrally linearly moved in the third direction D3 with respect to each other by the fourth drive motors 156 on both sides in the first direction D1.
[0110] The fourth drive motors 156 may include second pinions 157 disposed at the lower side of the sixth plate 155 in the second direction D2.
[0111] The second racks 158 may be disposed on the inner side of any one of the mounting frame pairs 152 in the first direction D1. The second racks 158 may have a shape extending in the third direction D3.
[0112] The second racks 158 may be configured to engage with the second pinions 157 by actuating the fourth drive motors 156 by the controller.
[0113] Through the gear engagement of the second racks 158 and the second pinions 157, the sixth plate 155 may move in the third direction D3. The sixth plate 155 may linearly move through the engagement of the second racks 158 and the second pinions 157, and the holding unit 120 in a state where the cylinder core part 11 is disposed is provided on the sixth plate.
[0114] That is, in a state where the cylinder core part 11 is again disposed on the holding unit pair 120, when the cylinder 10 aligned in the first direction D1 is lowered by the lowering of the lifting unit pair 130, the sixth plate 155 linearly moves in the third direction D3 by the driving of the fourth drive motors 156, and thus the holding unit pair 120 also moves in the third direction D3, so that the cylinder 10 can be transferred to the stacker crane.
[0115] Figure 10 is a flowchart showing a cylinder transfer method according to some embodiments of the present disclosure.
[0116] Refer to Figure 10 , the cylinder core parts 11 on both sides of the cylinder 10 carried and stored by the unmanned transport vehicle or the forklift are respectively disposed on the holding unit pair 120 (S110).
[0117] The carried and stored cylinders 10 may be between the holding unit pairs 120 disposed to face each other with a space therebetween in the first direction D1. Subsequently, the cylinder core parts 11 on both sides of the cylinder 10 are disposed on the holding unit pair 120.
[0118] In a state where the cylinder core part 11 is disposed on the mounting rollers pair 122 of the holding unit 120, the controller actuates the third drive motor 146 of the alignment unit 140, so that the hand blocks B of the alignment unit pair 140 disposed on both sides of the cylinder 10 are respectively inserted into the cylinder core parts 11 on both sides of the cylinder 10 in the first direction D1.
[0119] When the fifth plate 143 (moving plate) moves along the first direction D1 driven by the third drive motor 146, the hand block B is also inserted into the core part 11 while moving along the first direction D1 (S120).
[0120] When the inner diameter detection sensor S of the hand block B inserted into the core part 11 detects the inner diameter of the core part 11, the controller stops the insertion of the hand block B.
[0121] The controller actuates the second drive motor 135 in a state where the hand block B is inserted into the core part, so that the cylinder 10 is lifted and lowered along the second direction D2 by the lifting unit pair 130 spaced apart from each other along the first direction D1 (S130).
[0122] Subsequently, the controller calculates the distances from the initial positions of each of the core parts 11 on both sides in the first direction D1 to the positions where the inner diameter detection sensor S detects the inner diameter of the core part 11 while the cylinder 10 is lifted and lowered along the first direction D1 in an eccentric state.
[0123] The controller allows the third drive motor 146 of each of the alignment unit pairs 140 to be driven with different strokes according to the calculated distances. The fifth plate 143 (moving plate), the extension frame 149, and the hand block B of each of the alignment unit pairs 140 also move integrally along the first direction D1 with different strokes together with the cylinder 10 by the third drive motor 146 driven with different strokes, so that the cylinder 10 eccentric along the first direction D1 is aligned along the first direction D1 (S140).
[0124] When the position of the cylinder 10 is aligned along the first direction D1, the controller actuates the second drive motor 135 again, so that the cylinder 10 is lowered along the second direction D2 by the lowering of the cylinder 10 along the second direction D2 by the lifting unit pair 130, so that the core parts 11 on both sides in the first direction D1 are again installed on the holding unit pair 120 (S150).
[0125] Subsequently, the controller drives the first drive motor 124 to rotate either one of the installation roller pairs 122, and rotates the core part 11 and rotates the cylinder 10 by the rotation of the installation roller 122.
[0126] When the core part 11 is set at a specific position in a state where the cylinder 10 and the core part 11 are continuously rotating, the barcode reader recognizes the unique identification number provided at the specific position, so that the material wound on the cylinder 10 can be recognized and the recognition signal is sent to the controller (S160).
[0127] When the unique identification number of the cylinder 10 is recognized, the controller stops the drive of the first drive motor 124 to stop the rotation of the cylinder 10.
[0128] Subsequently, the controller drives the fourth drive motor 156 to linearly move the sixth plate 155 in the third direction D3, so that the holding unit pairs 120 provided on the sixth plate 155 of each of the transfer unit pairs 150 can also linearly move in the third direction D3 to transfer the cylinder 10 installed on the holding unit pairs 120 to the stacker crane (S170).
[0129] When the transfer of the cylinder 10 is completed, the controller operates the fourth drive motor 156 again so that the holding unit pairs 120 can return to their original positions by the sixth plate 155 moving in the direction opposite to the third direction D3, so that the alignment and transfer processes of the cylinder 10 can be continuously performed.
[0130] As described above, in the cylinder transfer device and method according to some embodiments of the present disclosure, in a state where the cylinder 10 stored in a left eccentric or right eccentric state is lifted and lowered by the lifting unit 130 to minimize friction, instead of pressing the cylinder core 11 with the same force from both the left and right sides, by calculating the distance detected by the inner diameter detection sensor S from the initial position where the cylinder core is stored, the alignment units 140 on both the left and right sides move with different strokes in the left-right direction together with the cylinder 10 to align the cylinder, thereby simplifying the centering operation and improving the position accuracy during the transfer operation to improve the reliability of the cylinder centering operation.
[0131] Although embodiments of the present disclosure have been described with reference to the drawings, it is obvious to those skilled in the art that the present disclosure can be embodied in other specific forms without departing from the technical idea and basic features of the present disclosure. Therefore, the above embodiments should be considered illustrative in all respects and not restrictive.
