Description

[Technical Field]

[0001] One aspect of the present invention relates to an automated warehouse system. [Background technology]

[0002] There is known a loading device for loading a roll material (coil material) in which a product is wound around a shaft core extending in one direction onto a pallet. For example, Patent Document 1 shown below discloses a loading device that loads roll material that has been lowered by an overhead crane in a vertical position (a position in which the shaft core extends horizontally) onto a pallet in a horizontal position (a position in which the shaft core extends vertically). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2017-122001 Summary of the Invention [Problem to be solved by the invention]

[0004] However, pallets, which are commonly used as transportation means, are generally large in size, and storing roll materials on pallets in an automated warehouse requires space. For this reason, there is a demand for roll materials that have been transported on pallets to be stored separately from the pallets.

[0005] Therefore, an object of one aspect of the present invention is to provide an automated warehouse system that can separate roll material that has been transported on a pallet from the pallet and store it in a rack. [Means for solving the problem]

[0006] An automated warehouse system according to one aspect of the present invention provides a rack for storing roll material, with the product wound around an axis extending in one direction, the rack having a support part for supporting the product part, a stacker crane having a transfer part capable of supporting the product part of the roll material and for loading and unloading the roll material into the rack, a roll turning device having a rotating member including a first arm that can be inserted into an insertion hole formed in a pallet and a second arm that can support the product part of the roll material, and a rotation drive part that rotates the rotating member about a horizontal axis as a rotation axis, and a loading member on which the roll material can be placed, the stacker crane and the roll turning device and a controller for controlling the roll turning device and the conveying device, wherein when a first state is defined as a state of the turning member in which a first arm is inserted into an insertion hole of a pallet with roll material placed thereon so that the axis of the pallet extends in the vertical direction, and a second state is defined as a state of the turning member in which a second arm supports the roll material so that the axis of the roll material extends in the horizontal direction, the controller controls the turning device to change the turning member from the first state to the second state, and after the turning member has rotated to the second state, controls the conveying device to transport the loading member with the roll material placed thereon to the stacker crane.

[0007] In an automated warehouse system with this configuration, the pallet on which the roll material is placed can be rotated to separate the roll material from the pallet and transfer it to a conveying device. The conveying device then transfers the transferred roll material to a stacker crane, which then transfers the roll material to a rack. In other words, in an automated warehouse system with this configuration, roll material that has been transported on a pallet can be separated from the pallet and stored in a rack.

[0008] In one aspect of the automated warehouse system of the present invention, when the extension direction of the rotation axis of the rotation device in the second state is defined as a first direction and the direction perpendicular to the first direction is defined as a second direction, the conveying device has a switching unit that switches the conveying direction of the roll material from the first direction to the second direction or from the second direction to the first direction, the rack is configured to store multiple roll materials along the first direction, and the stacker crane is configured to be movable along the first direction and may transfer the roll materials along the second direction. In this configuration, the roll materials are stored in the rack so that the extension direction of the axis of the roll material coincides with the extension direction of the rack. Racks are generally more resistant to shaking in the extension direction than to shaking in the width direction, so the amount of shifting of the roll material during an earthquake can be reduced.

[0009] In an automated warehouse system according to one aspect of the present invention, the conveying devices may be arranged in a plurality of rows along the movement direction of the stacker crane, and may have a plurality of connection sections that can be used for transfer by the stacker crane, and a sorting section that transports the loaded material along the arrangement direction of the plurality of connection sections. With this configuration, the conveying devices can deliver the roll material to one of the connection sections while the stacker crane is placing the roll material on the rack, or the stacker crane can deliver the roll material to one of the connection sections while the conveying device is transporting the roll material, thereby improving transport efficiency.

[0010] In an automated warehouse system according to one aspect of the present invention, a mounting member may be provided corresponding to each of the plurality of connection sections, and when one mounting member is between the sorting section and the roll rotating device, the controller may prohibit other mounting members from being sent out from the connection section. This configuration reliably prevents the mounting members from colliding with each other on the conveying device. [Effects of the Invention]

[0011] According to one aspect of the present invention, roll material that has been transported on a pallet can be separated from the pallet and stored in a rack. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] An automated warehouse system 100 according to one embodiment will be described below with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated descriptions will be omitted.

[0014] The automated warehouse system 100 is a system that separates roll material R that is transported on a pallet P from the pallet P and stores the roll material R in a rack 7. As shown in FIG. 1 , the automated warehouse system 100 includes a first conveying device 1, a roll rotating device 2, a second conveying device (conveying device) 3, a stacker crane 5, a rack 7, and a controller 9. For ease of explanation, in this embodiment, the conveying direction of the first conveying device 1 may be referred to as the X direction (second direction), the direction perpendicular to the X direction in a plan view as the Y direction (first direction), and the vertical direction as the Z direction. The X direction, Y direction, and Z direction are perpendicular to one another.

[0015] The first conveying device 1 conveys the roll material R placed on the pallet P in the X direction from the upstream process on the upstream side to the roll turning device 2. As shown in FIGS. 5(A) and 5(B), the pallet P is a loading platform having a loading surface F on which the roll material R is placed and insertion holes H for inserting the forks of a forklift. The roll material R has a product RP wound around a shaft C. Examples of the product RP include steel plate, copper plate, aluminum plate, electric wire (cable), paper, fiber, thread, etc. The portion that becomes the shaft C may be provided with a core material or may be hollow.

[0016] Fig. 5(A) shows the roll material R placed on the pallet P as viewed from the conveying direction (X direction) of the first conveying device 1, and Fig. 5(B) shows the roll material R placed on the pallet P as viewed from the Y direction. The pallet P is placed on the first conveying device 1 so that the extension direction of the insertion holes H of the pallet P coincides with the X direction.

[0017] As shown in Figures 1 and 2, the first conveying device 1 has first conveyors 11 and a guide unit 13. The first conveyors 11 support both ends of the underside of the pallet P and convey it. The first conveyors 11 are belt conveyors or chain conveyors. The guide unit 13 is disposed at the downstream end of the first conveying device 1. The guide unit 13 guides the pallet P, which has been conveyed to the downstream end of the first conveying device 1, to a predetermined position. In this embodiment, the first arm 21 of the rotating member 23 in the first state guides the pallet P so that it is inserted into the insertion hole H.

[0018] The roll rotating device 2 includes a rotating member 23 and a rotation drive unit 25. The rotating member 23 includes two first arms 21, 21 that can be inserted into insertion holes H formed in the pallet P and two second arms 22, 22 that can support the product portions RA of the roll material R. The extension directions of the two first arms 21, 21 and the extension directions of the two second arms 22, 22 are perpendicular to each other. The second arms 22, 22 have contact portions 22A, 22A at their contact points with the product portions RA. The contact portions 22A, 22A are formed of a material such as resin so as not to damage the product portions upon contact. The rotation drive unit 25 rotates the rotating member 23 about a rotation axis 24 that extends horizontally. The rotation drive unit 25 is controlled by the controller 9.

[0019] The rotating member 23 is rotatable about a horizontal axis as a rotation axis 24 between a first state (see FIG. 3(A)) in which the two first arms 21 extend along the X direction and the two second arms 22 extend along the Z direction, and a second state (see FIG. 3(B)) in which the two first arms 21 extend along the Z direction and the two second arms 22 extend along the X direction. More specifically, the rotating member 23 rotates from the first state in which the first arms 21 are inserted into the insertion holes H of the pallet P on which the roll material R is placed so that the axis C extends vertically, to a second state in which the second arms 22 support the roll material R so that the axis C of the roll material R extends horizontally. When the rotating member 23 rotates to the second state, the transfer of the roll material R to the second conveyor 3 is completed. In other words, when the rotation of the rotating member 23 is completed, the roll material R is handed over to the skid S. When the rotation of the rotating member 23 is completed, the roll material R is separated from the pallet P (it has no part supported by the pallet P).

[0020] The second conveying device 3 conveys a skid (placing member) S, on which roll material R can be placed, in both directions between the stacker crane 5 and the roll turning device 2. Specifically, the second conveying device 3 conveys the skid S between a position where the roll material R is transferred by the stacker crane 5 and a position where the roll material R is transferred by the roll turning device 2. As shown in FIG. 1 , the second conveying device 3 has a first conveying section 31, a switching section 33, a second conveying section 35, a sorting section 37, and two connecting sections 39, 39.

[0021] The skid S is a member on which the product portion RA of the roll material R can be placed. As shown in FIG. 6(B), the skid S has a first flat plate portion S1, an upright portion S2 extending from the first flat plate portion S1, a second flat plate portion S3 connected to the upright portion S2 and supporting the roll material R, and a contact portion S4 that contacts the roll material R. The upright portion S2, the second flat plate portion S3, and the contact portion S4 form a placement portion S5 on which the roll material R is placed. Four placement portions S5 are formed at the four corners of the first flat plate portion S1. That is, the skid S supports the roll material R using the four placement portions S5. The two placement portions S5, S5 arranged in the Y direction are spaced apart so that the second arms 22, 22 can fit therein. In this embodiment, two skids S, S are provided, and two (plural) skids are provided corresponding to two (plural) connection portions 39, 39, which will be described in detail later.

[0022] As shown in FIGS. 1 to 4, the first conveying section 31 receives the roll material R from the roll turning device 2 in a state in which the extension direction of the axis C of the roll material R is the X direction. The received roll material R is placed on four placement sections S5. The first conveying section 31 conveys the skid S on which the roll material R is placed or the empty skid S on which the roll material R is not placed along the X direction.

[0023] The first conveying section 31 includes second conveyors 31A, a second drive section 31B, and a guide section 32. The second conveyors 31A support both ends of the underside of the skid S and convey it. The second conveyor 31A is a belt conveyor or a chain conveyor. The second drive section 31B drives the second conveyors 31A. The guide section 32 is arranged along the extension direction of the second conveyors 31A. The guide section 32 guides an empty skid S, which is not carrying a roll material R and which has been transported from the switching section 33 to the first conveying section 31, to a predetermined position. In this embodiment, when the two second arms 22 of the rotating member 23 in the first state rotate to the second state, the guide section 32 guides the empty skid S, which is not carrying a roll material R, to enter between two sets of two placement sections S5 arranged in the Y direction.

[0024] 1 and 6(A), the switching unit 33 switches the conveying direction of a skid S carrying a roll material R or an empty skid S carrying no roll material R, which is conveyed along the X direction, to the Y direction, and conveys the skid S along the Y direction. Also, the switching unit 33 switches the conveying direction of a skid S carrying a roll material R or an empty skid S carrying no roll material R, which is conveyed along the Y direction, to the X direction, and conveys the skid S along the X direction.

[0025] The switching unit 33 includes third conveyors 33A, a third drive unit 33B, fourth conveyors 33C, a fourth drive unit 33D, and a guide unit 33E. The third conveyors 33A are belt conveyors or chain conveyors, and transport skids S carrying roll material R or empty skids S carrying no roll material R along the X direction. The third drive unit 33B drives the third conveyors 33A. The fourth conveyors 33C are belt conveyors or chain conveyors, and transport skids S carrying roll material R or empty skids S carrying no roll material R along the Y direction. The fourth drive unit 33D drives the fourth conveyors 33C.

[0026] The third conveyors 33A, 33A are provided so as to be able to move up and down between an upper position and a lower position. The third conveyors 33A, 33A are driven to move up and down by a drive unit (not shown). When the third conveyors 33A, 33A are located in the upper position, the third conveyors 33A, 33A are located above the fourth conveyors 33C, 33C, and when the third conveyors 33A, 33A are located in the lower position, the third conveyors 33A, 33A are located below the fourth conveyors 33C, 33C. That is, when transporting a skid S with roll material R placed thereon or an empty skid S without roll material R placed thereon along the X direction, the third conveyors 33A, 33A are driven in the upper position, and when transporting a skid S with roll material R placed thereon or an empty skid S without roll material R placed thereon along the Y direction, the third conveyors 33A, 33A are driven in the lower position and the fourth conveyors 33C, 33C are driven.

[0027] The guide portion 33E is disposed along one of the fourth conveyors 33C, and is disposed on the opposite side of the pair of fourth conveyors 33C, 33C from the first transport portion 31. The guide portion 33E functions as a stopper for the roll material R transported in the X direction by the third conveyors 33A, 33A.

[0028] The second transport section 35 has fifth conveyors 35A, 35A, a fifth drive section 35B, and guide sections 35C, 35C. The fifth conveyors 35A, 35A support both ends of the underside of the skid S and transport it. The fifth conveyors 35A, 35A are belt conveyors or chain conveyors. The fifth drive section 35B drives the fifth conveyors 35A, 35A. The guide sections 35C, 35C are arranged along the extension direction of the fifth conveyors 35A, 35A, and are arranged to sandwich the fifth conveyors 35A, 35A. The guide sections 35C, 35C guide the skid S in the Y direction to prevent the position of the skid S from shifting in the X direction.

[0029] The sorting unit 37 transports skids S carrying roll material R or empty skids S carrying no roll material R in the Y and X directions along the arrangement direction (X direction) of the two (plural) connecting units 39. The sorting unit 37 moves the skids S carrying the skids S in the X direction to sort the skids S to one connecting unit 39 or the other connecting unit 39. The sorting unit 37 includes sixth conveyors 37A, a sixth drive unit 37B, guide units 37C, and a running unit 37D. The sixth conveyors 37A support both ends of the underside of the skids S while transporting them. The sixth conveyors 37A are belt conveyors or chain conveyors. The sixth drive unit 37B drives the sixth conveyors 37A. The guide units 37C are arranged along the extension direction of the sixth conveyors 37A, sandwiching the sixth conveyors 37A. The guide units 37C guide the skid S in the Y direction to prevent the position of the skid S from shifting in the X direction. The running unit 37D moves the sixth conveyors 37A, the sixth drive unit 37B, and the guide units 37C along the Y direction.

[0030] Two (or more) connection sections 39, 39 are arranged along the movement direction (X direction) of the stacker crane 5. The connection sections 39, 39 transport skids S on which roll material R is placed or empty skids S on which no roll material R is placed in the Y direction between the sorting section 37 and the stacker crane 5 (positions where transfer by the stacker crane 5 is possible). The connection sections 39, 39 are transport sections arranged at positions where the stacker crane 5 can transfer the roll material R.

[0031] Each of the connecting portions 39, 39 transports a skid S with a roll material R placed thereon or an empty skid S without a roll material R placed thereon in the Y direction. Each of the connecting portions 39, 39 has a seventh conveyor 39A, a seventh drive unit 39B, and guide units 39C, 39C. The seventh conveyors 39A, 39A support both ends of the underside of the skid S while transporting it. The seventh conveyors 39A, 39A are belt conveyors or chain conveyors. The seventh drive unit 39B drives the seventh conveyors 39A, 39A. The guide units 39C, 39C are arranged along the extension direction of the seventh conveyors 39A, 39A, and are arranged to sandwich the seventh conveyors 39A, 39A. The guide units 39C, 39C guide the skid S in the Y direction to prevent the skid S from shifting in the X direction.

[0032] The stacker crane 5 has a transfer section 57 capable of supporting the product portion RA of the roll material R, and transfers the roll material R into and out of the rack 7. The stacker crane 5 is provided so as to be movable in the X direction, and transfers the roll material R along the Y direction. The transfer section 57 of the stacker crane 5 is a so-called sliding fork of a body support.

[0033] The stacker crane 5 mainly includes a traveling section 51, a mast 53, a lifting section 55, and a transfer section 57. The traveling section 51 moves along the X direction while supporting the mast 53 and the transfer section 57. The traveling section 51 is driven by a drive section (not shown). The mast 53 is a columnar member erected from the traveling section 51 and extending in the Z direction. The lifting section 55 is provided so as to be movable up and down along the extension direction of the mast 53. The lifting section 55 is driven by a drive section (not shown). The transfer section 57 is provided on the lifting section 55. The transfer section 57 is provided so as to be extendable in the Y direction. The transfer section 57 extends and contracts to transfer the roll material R between the rack 7 and the connection section 39. As shown in FIG. 7(C), the transfer section 57 has a recess 57A formed therein that supports the roll material R. The recess 57A extends in the X direction. The recess 57A is provided in approximately the center of the transfer section 57 in the Y direction. The recess 57A is provided to support the product portion RA of the roll material R, and stably positions the roll material R.

[0034] As shown in Figures 1, 7(A), and 7(B), the rack 7 stores a plurality of roll materials R. The rack 7 has a pillar portion 71, a support portion 73, and a storage portion 75. The pillar portion 71 extends in the Z direction. In this embodiment, a pair of pillar portions 71, 71 arranged at a predetermined interval in the Y direction are aligned in the X direction. The support portion 73 is a member that supports the roll materials R and is attached so as to straddle the pair of pillar portions 71, 71.

[0035] As shown in FIG. 7(A), the roll material R is supported by two support portions 73, 73 adjacent to each other in the X direction. The storage portion 75 is configured to be able to store the roll material R by these two support portions 73. As shown in FIG. 7(B), each of the multiple roll materials R is supported by the support portion 73 with the axis C extending in the X direction. A recess 73A is formed in the support portion 73 and is located approximately in the center of the support portion 73 in the Y direction. The recess 73A is arranged to support the product portion RA of the roll material R and stably position the roll material R. The storage portions 75 are arranged in both the X direction and the Z direction.

[0036] 1, the racks 7 are arranged opposite each other in the Y direction. More specifically, the two racks 7, 7 are arranged opposite each other in the Y direction so as to sandwich the travel area of ​​the stacker crane 5 extending in the X direction.

[0037] The controller 9 controls the roll turning device 2, the second conveying device 3, and the stacker crane 5. The controller 9 is provided so as to be able to communicate with the roll turning device 2, the second conveying device 3, and the stacker crane 5 by wire or wirelessly. The controller 9 is disposed, for example, on the machine base of the first conveying section 31 that constitutes the second conveying device 3.

[0038] The controller 9 rotates the rotation shaft 24 of the rotation member 23 by 90 degrees around the horizontal axis. Specifically, the controller 9 controls the rotation drive unit 25 to rotate the rotation member 23 from a first state in which the first arms 21, 21 are inserted into the insertion holes H of the pallet P on which the roll material R is placed so that the extension direction of the axis C of the roll material R is along the vertical direction to a second state in which the second arms 22, 22 support the roll material R so that the extension direction of the axis C of the roll material R is along the horizontal direction. After the rotation member 23 has rotated to the second state, the controller 9 controls the second conveyance device 3 to transport the skid S on which the roll material R is placed to the stacker crane 5, and after the skid S has withdrawn from the roll turning device 2, controls the rotation drive unit 25 to return the rotation member 23 to the first state.

[0039] As described above, the two skids S are arranged corresponding to the multiple connection sections 39, respectively. The controller 9 controls the second conveying device 3 so that when one skid S is between the sorting section 37 and the roll turning device 2, the other skids S are not sent out from the connection section 39. The same number of skids S (two in this embodiment) as the number of connection sections 39 are arranged, and each skid S has a predetermined connection section 39 (two in this embodiment) to which it will arrive. For example, while the roll turning device 2 is transferring the roll material R to the first conveying section 31, the controller 9 causes an empty skid S to wait at the connection section 39 on the right side shown in FIG. 1, and then conveys the skid S carrying the roll material R in the first conveying section 31 to the connection section 39 on the left side shown in FIG. 1, and then conveys the empty skid S at the connection section 39 on the right side shown in FIG. 1 to the first conveying section 31.

[0040] Whether or not a skid S is present on the second conveying device 3 can be determined, for example, by appropriately installing a sensor to detect the skid S on the conveying path of the second conveying device 3, or by managing the operating status of each piece of equipment that makes up the automated warehouse system 100.

[0041] The effects of the automated warehouse system 100 of the above embodiment will be described. In the automated warehouse system 100 of the above embodiment, the roll material R can be separated from the pallet P and handed over to the second conveying device 3 by rotating the pallet P on which the roll material R is placed. The handed over roll material R is then handed over to the stacker crane 5 by the second conveying device 3, and the stacker crane 5 transfers the roll material R to the rack 7. In other words, in the automated warehouse system 100 configured as described above, the roll material R that has been transported while placed on the pallet P can be separated from the pallet P and stored in the rack 7.

[0042] In the automated warehouse system 100 of the above embodiment, the conveying device has a switching unit 33 that switches the conveying direction of the roll material from the X direction to the Y direction or from the Y direction to the X direction, the rack 7 is configured to be able to store multiple roll materials R along the X direction, and the stacker crane 5 is provided to be able to move along the X direction and transfers the roll material along the Y direction. As a result, the roll material R is stored in the rack 7 so that the extension direction of the axis C of the roll material R coincides with the extension direction (X direction) of the rack 7. Generally, the rack 7 is more resistant to vibration in the extension direction than to vibration in the width direction (direction perpendicular to the extension direction), so the amount of displacement of the roll material R during an earthquake can be reduced.

[0043] In the automated warehouse system 100 of the above embodiment, the second conveying device 3 has two connection parts 39, 39 and a sorting part 37. This makes it possible for the second conveying device 3 to transfer the roll material R to one of the connection parts 39 while the stacker crane 5 is placing the roll material R on the rack 7, or for the stacker crane 5 to transfer the roll material R to one of the connection parts 39 while the second conveying device 3 is transporting the roll material R, thereby improving transport efficiency.

[0044] In the automated warehouse system 100 of the above embodiment, the controller 9 prohibits other skids S from being sent out from the connection section 39 when one skid S is between the sorting section 37 and the roll rotating device 2, thereby reliably preventing one skid S from interfering with other skids S on the second conveying device 3.

[0045] Although one embodiment has been described above, one aspect of the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the invention.

[0046] In the above embodiment of the automated warehouse system 100, an example has been described in which the second conveying device 3 is provided with a switching unit 33 that switches the conveying direction of the skid S, but the system may also be configured not to include the switching unit 33. That is, the second conveying device 3 may be configured to convey the skid S carrying the roll material R in the X direction to the rack 7 after receiving the roll material R from the roll turning device 2 without switching the conveying direction. In this case, the rack 7 is arranged to extend along the Y direction (i.e., so that the storage unit 75 is aligned in the Y direction). The rack 7 may store the roll material R in a state in which the extension direction of the axis C extends in the Y direction.

[0047] In the above-described embodiment and modified example of the automated warehouse system 100, an example has been described in which the second conveying device 3 has two connection parts 39, 39, but only one connection part 39 may be provided, or three or more connection parts 39 may be provided. As a modified example, when only one connection part 39 is provided, the sorting part 37 may not be provided.

[0048] In the above embodiment and modified example of the automated warehouse system 100, an example has been described in which the sorting section 37 moves in the X direction, but multiple connection sections 39 and the roll rotating device 2 may be connected by providing, for example, a branch conveyor or the like.

[0049] In the above-described embodiment and modified example of the automated warehouse system 100, the roll material R supplied via the first conveying device 1 is changed in position by the roll turning device 2 and stored in the rack 7. However, the present invention is not limited to this. For example, the roll material R removed from the rack 7 may be changed in position by the roll turning device 2 and sent to the first conveying device 1. In this case, the roll turning device 2 does not necessarily need to return the rotating member 23 from the second state to the first state after the skid S is withdrawn from the roll turning device 2. The rotating member 23 may be rotated from the second state to the first state only when subsequent (continuous) storage is to be performed. In other words, when receiving the roll material R removed from the rack 7 after the skid S is withdrawn, the roll turning device 2 may remain in the second state without returning from the second state to the first state.

[0050] In the above embodiment and modified example of the automated warehouse system 100, a stacker crane 5 has been used as an example of a device for transferring roll material R to the rack 7, but a shuttle conveying device that moves on rails laid along the extension direction of the rack 7, a lifting device that moves along the up and down direction of the rack 7, or a combination of these devices may also be applied.
