Description

The present invention relates to a station device and an automated warehouse system.

As an example of technology related to station devices, Patent Document 1 describes a positioning device for transferring a pallet on which items are placed to a stacker crane. In the positioning device described in Patent Document 1, the items and pallet are transferred to a loading mechanism, and the items and pallet are positioned together by a centering device.

JP 2011-111273 A

In the above-mentioned technology, when a pallet carrying a roll is transferred to a station device, the roll and pallet are positioned together, so even if the roll is misaligned with respect to the pallet, the misalignment is not eliminated. Therefore, for example, when the roll and pallet are supplied from the station device to a manufacturing device, there is a risk that the roll will interfere with the manufacturing device.

The present invention aims to provide a station device and an automated warehouse system that can position pallets and rolls.

The station device according to the present invention is a station device onto which a pallet having a receiving member for a roll of core material is transferred, and includes a pallet support section that supports the underside of the pallet, a core material support section that is positioned above the pallet support section and supports the core material from below, a pallet guide section that guides the pallet so that the position of the pallet supported by the pallet support section is determined, and a core material guide section that guides the core material so that the position of the core material supported by the core material support section is determined, and in the vertical direction, the distance from the upper surface of the pallet support section to the point of contact of the core material support section with the core material is greater than the distance from the underside of the pallet to the point of contact of the receiving member with the core material.

When a pallet carrying a roll is transferred, this station device can support the roll's core material and the pallet in a separate state, and the supported pallet and core material can be positioned by the pallet guide section and the core material guide section, respectively. This makes it possible to position the pallet and roll separately.

In the station device according to the present invention, the pallet guide section may be provided adjacent to and above the pallet support section, and the core material guide section may be provided adjacent to and above the core material support section. In this case, the above-mentioned effect of enabling the positioning of the pallet and rolls can be specifically realized. In addition, when the pallet is transferred to the station device by a stacker crane or a transport vehicle, the amount of movement of the pallet in the vertical direction can be reduced.

In the station device according to the present invention, a travel space in which the transport vehicle can travel may be provided below the pallet support section. In this case, the transport vehicle can enter the station device by utilizing the travel space.

In the station device according to the present invention, the pallet guide section and the core material guide section may respectively guide the pallet and the core material so that the center position of the core material in the first direction in which the core material extends coincides with the center position of the pallet in the first direction. In this case, it becomes possible to center the pallet and the core material in the first direction.

In the station device according to the present invention, the surface of the pallet guide section and the surface of the core material guide section may be formed of resin. In this case, it is possible to suppress the generation of metal powder due to wear of the pallet guide section and the core material guide section.

The automated warehouse system according to the present invention may include the above-mentioned station device, a rack in which pallets are stored, a stacker crane that travels along a track and transfers the pallets, and a control unit that controls the stacker crane. Since this automated warehouse system includes the above-mentioned station device, it can achieve the above-mentioned effect of being able to position the pallets and rolls respectively.

In the automated warehouse system according to the present invention, the station device is adjacent to the track, and the control unit may execute control to control the stacker crane to transfer the pallet to the station device when the pallet is to be removed from the warehouse. In this case, when the pallet is to be removed from the warehouse, the pallet can be transferred to the station device and each can be positioned.

The automated warehouse system according to the present invention includes another station device, separate from the station device, to which the pallet is transferred and which supports the underside of the pallet without supporting the core material, and the other station device is adjacent to the track, and when the pallet is to be removed from the warehouse, if the pallet has been transferred to the station device at least once, the control unit may execute control to control the stacker crane to transfer the pallet to the other station device. In this case, when the pallet is to be removed from the warehouse, if the pallet has been transferred to the station device at least once, each of the station devices has already been positioned, so that the pallet can be transferred to the other station device and removed from the warehouse without repositioning each of the station devices.

The automated warehouse system according to the present invention includes another station device, separate from the station device, to which the pallet is transferred and which supports the underside of the pallet without supporting the core material, and the other station device is adjacent to the track, and the control unit may execute control to transfer the pallet to the station device when the pallet is stored, and execute control to control the stacker crane to transfer the pallet to the other station device when the pallet is removed from the warehouse. In this case, when the pallet is stored, the pallet is transferred to the station device and each can be positioned.

The present invention provides a station device and an automated warehouse system that can position pallets and rolls.

The following describes the embodiments in detail with reference to the drawings. In the description of each drawing, the same or corresponding parts are given the same reference numerals, and duplicate descriptions may be omitted.

As shown in FIG. 1, the automated warehouse system 1 is a system that stores pallets 20 carrying rolls 10 received from, for example, an external supplier, and supplies the rolls 10 to manufacturing equipment in a factory using an automated guided vehicle. The automated warehouse system 1 includes an automated warehouse 30 that stores the pallets 20, an automated guided vehicle 40 that transports the pallets 20, a conveyor 60 that transports the pallets 20, and a controller (control unit) 100 that is a control device that manages the automated warehouse system 1. The automated warehouse 30 includes racks 50, a stacker crane 70, and station equipment 80.

In the following, the terms "upper" and "lower" correspond to the upper and lower vertical directions. The "Z direction" is the vertical direction, which is the row direction of the racks 50. The "X direction" is the horizontal direction, which is the longitudinal direction of the racks 50. The "Y direction" is the horizontal direction perpendicular to the X and Z directions, which is the direction in which the racks 50 are arranged side by side.

The automated warehouse 30 is installed, for example, inside a building. The automated warehouse 30 stores the pallets 20 transported by the conveyor 60 in the racks 50 using the stacker crane 70. The automated warehouse 30 transfers the pallets 20 stored in the racks 50 to the station device 80 using the stacker crane 70. The automated guided vehicle 40 lifts the pallets 20 transferred to the station device 80 and transports them to manufacturing equipment in the factory.

In the automated warehouse 30, the racks 50 are arranged in pairs, facing each other with a gap in the Y direction, with the X direction as the longitudinal direction. The racks 50 have multiple placement sections on which the pallets 20 are placed one by one. The placement sections are arranged in the X direction and the Z direction. The racks 50 store the pallets 20 in a matrix in the X direction and the Z direction. A first rack 50A, which is one rack 50 of a pair of adjacent racks 50, and a second rack 50B, which is the other rack 50, are arranged adjacent to each other and facing each other, for example. The racks 50 may store pallets carrying other materials, etc.

The conveyor 60 is a device that transports the pallets 20. At the destination of the conveyor 60, the conveyor 60 is adjacent to a running rail 71 (described later) of a stacker crane 70. In this embodiment, the conveyor 60 constitutes a storage station in the automated warehouse 30. For example, the pallets 20 are transferred onto the conveyor 60 directly from the automated guided vehicle 40 or via an overhead crane or robot arm (not shown) (the same applies below). After being transported by the conveyor 60, the pallets 20 are stored in the rack 50 by the stacker crane 70.

The stacker crane 70 travels along a traveling rail (track) 71 that is installed in the X direction between the racks 50 facing each other in the Y direction in each automated warehouse 30. The stacker crane 70 includes a traveling cart that can travel along the traveling rail 71, and a lifting platform that can be raised and lowered along a mast on the traveling cart and is provided with a transfer device. The stacker crane 70 transports the pallet 20 between the placement part of the rack 50 and the conveyor 60 installed outside the rack 50 and the station device 80 installed inside the rack 50. The stacker crane 70 transfers (loads and unloads) the pallet 20 to the placement part of the rack 50, the conveyor 60, and the station device 80. The operation of the stacker crane 70 is controlled by the controller 100.

The stacker crane 70 is not particularly limited, and various known stacker cranes can be used. In this embodiment, the stacker crane 70 is a fork type that scoops up and transfers the pallet 20 with a slide fork. The stacker crane 70 may be, for example, a clamp type that clamps both sides of the pallet 20 to hold it and transfer it.

The station device 80 is a device to which the pallet 20 is transferred. In this embodiment, the station device 80 is provided inside the rack 50 and adjacent to the running rail 71. The station device 80 is provided, for example, in place of multiple placement units arranged in the lower layer of the rack 50. The station device 80 is provided with a running space in which the automatic guided vehicle 40 can run. The station device 80 constitutes an outgoing station in the automatic warehouse 30. That is, in this embodiment, there is only one type of outgoing station. When the pallet 20 is outgoing from the automatic warehouse 30, the stacker crane 70 transfers the pallet 20 from the rack 50 to the station device 80. The pallet 20 transferred to the station device 80 is transported to a manufacturing device in the factory by the automatic guided vehicle 40.

The automated guided vehicle 40 is a transport cart that travels unmanned on the floor surface F. An AGV (Automatic Guided Vehicle) is used as the automated guided vehicle 40. Hereinafter, the "automated guided vehicle 40" will be simply referred to as the "transport vehicle 40". The transport vehicle 40 can transfer the pallet 20 from the station device 80. The transport vehicle 40 has a platform 41 that can be raised and lowered (moved in the Z direction). The transport vehicle 40 is, for example, a lifter-type AGV. The platform 41 has an upper surface 41a. The transport vehicle 40 lifts the pallet 20 with the upper surface 41a of the raised platform 41, and transports the pallet 20 while supporting the lower surface 21b (described later) of the pallet 20 with the upper surface 41a.

The transport vehicle 40 travels along the Y direction, approaches the rack 50, and enters the travel space provided in the station device 80. The transport vehicle 40 travels, for example, along a route that is set in advance for the rack 50. The transport vehicle 40 can travel based on a two-dimensional code such as a data matrix code or a QR code (registered trademark) installed on the floor surface F. The guidance method used by the transport vehicle 40 is not particularly limited, and may be, for example, a magnetic guidance type or a laser guidance type. The travel route of the transport vehicle 40 is configured, for example, by a magnetic tape (magnetic marker), a laser reflector, or a rail. The operation of the transport vehicle 40 is controlled by a controller 100.

The controller 100 is an electronic control unit consisting of a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The controller 100 controls various operations of the stacker crane 70, the transport vehicle 40, etc. The controller 100 can be configured as software in which a program stored in the ROM is loaded onto the RAM and executed by the CPU, for example. The controller 100 may also be configured as hardware such as electronic circuits. The controller 100 executes various controls by cooperation between hardware such as the CPU, RAM, and ROM and software such as programs.

The controller 100 controls the operation of the stacker crane 70. The controller 100 controls the stacker crane 70 so that the pallet 20 transported by the conveyor 60 is stored in the rack 50 by the stacker crane 70. When the pallet 20 is removed from the rack 50, the controller 100 controls, for example, the stacker crane 70 so that the pallet 20 is always transferred to the station device 80. In addition, the controller 100 controls the transport vehicle 40 so that the pallet 20 is transported from the station device 80 to a manufacturing device in the factory.

The roll 10, pallet 20, and station device 80 will be described in detail with reference to Figures 2 to 5.

As shown in FIG. 2, the roll 10 extends along the X direction (first direction). The roll 10 is, for example, a core material wrapped around a thin plate (core body). The roll 10 is, for example, a base material roll of an aluminum thin plate or a copper thin plate used in the secondary battery electrode plate manufacturing process. The roll 10 has a core material 10a and a roll body 10b. The roll 10 is taken out of a wooden box or the like by a worker or the like, and the core material 10a is placed on a receiving member 22 (described later) of the pallet 20 and placed on the pallet 20. The core material 10a is a member that holds an article, for example, a sheet-like or fibrous article, by wrapping the article around it, and is, for example, a rod-like member. The core material 10a is, for example, a resin or metal shaft body. The core material 10a has a first protrusion 11 that protrudes from one end side in the X direction to the outside of the roll body 10b, and a second protrusion 12 that protrudes from the other end side in the X direction to the outside of the roll body 10b. The roll 10 is placed on the pallet 20 by supporting the first protrusion 11 and the second protrusion 12 of the core material 10a on the pallet 20.

As shown in Figs. 2 and 3, the pallet 20 has a plate portion 21 extending along the X and Y directions, and two receiving members 22. The plate portion 21 is a rectangular plate with the thickness direction being in the Z direction. The plate portion 21 includes a planar upper surface 21a and a lower surface 21b. The plate portion 21 constitutes a base that can be lifted by the slide fork of the stacker crane 70 and the loading platform 41 of the transport vehicle 40. The pallet 20 is made of, for example, resin or metal. For example, the pallet 20 is a dedicated pallet for loading rolls 10.

The receiving member 22 is a member that receives the core material 10a of the roll 10 placed on the pallet 20. The receiving member 22 is erected on the upper surface 21a of the plate portion 21. The receiving member 22 extends along the Z direction. The receiving member 22 includes an end portion 23 provided on the upper side. The end portion 23 is shaped so as to be able to support the core material 10a from below, and forms a V-shaped groove that opens upward when viewed from the X direction, for example. The receiving members 22 are arranged side by side with a gap between them in the X direction. The gap between the two receiving members 22 corresponds to, for example, the length of the core material 10a.

The first receiving member 22A, which is located on one side of the two receiving members 22 in the X direction, receives the first protrusion 11 of the core material 10a at its end 23. The second receiving member 22B, which is located on the other side of the two receiving members 22 in the X direction, receives the second protrusion 12 of the core material 10a at its end 23. In other words, the core material 10a is supported by being supported at both ends by the first receiving member 22A and the second receiving member 22B. At this time, the inner surface of each end 23 abuts against the first protrusion 11 and the second protrusion 12.

The station device 80 is placed on a pallet 20 carrying a roll 10. The station device 80 has a number of support columns 81 extending in the Z direction, a pair of pallet support sections 82 that support the pallet 20 from below, a pallet guide section 83 provided adjacent to and above the pallet support sections 82, a pair of core material support sections 84 that support the core material 10a from below, and a pair of core material guide sections 85 provided adjacent to and above the core material support sections 84.

2, 3 and 4, the pair of pallet support parts 82 are fixed to and supported by a plurality of (for example, four) pillars 81. The plurality of pillars 81 may be pillars independent of the rack 50 in FIG. 1, or may be pillars of the rack 50. The pair of pallet support parts 82 are arranged to face each other in the X direction. The pair of pallet support parts 82 are, for example, rectangular frame-shaped extending in the Y direction, and are composed of four square steel pipes (square pipe material). The pair of pallet support parts 82 include an upper surface 82a and a lower surface 82b. Each upper surface 82a is, for example, flat, and supports the lower surface 21b of the pallet 20. The upper surfaces 82a are provided to be at the same height as each other in the Z direction, and are located on the same horizontal plane. The distance in the X direction between the pair of pallet support parts 82 (the gap between the pair of pallet support parts 82) is narrower than the width of the pallet 20 in the X direction. The distance in the X direction between the pair of pallet support parts 82 is wider than the width in the X direction of the loading platform 41 of the transport vehicle 40. The width in the Y direction between the pair of pallet support parts 82 is each larger than the width of the pallet 20 in the Y direction.

Below the pallet support 82, a travel space S is provided in which the transport vehicle 40 can travel. The travel space S is defined by four pillars 81 and the lower surface 82b of the pallet support 82. The travel space S is configured so that the transport vehicle 40 can pass along the Y direction. The lower surface 82b defining the travel space S is located above the loading platform 41 in the most lowered state (see Figures 2 and 3). The travel space S communicates with the space between the upper pallet support 82 and the core material support 84 through the atrium between the pair of pallet support parts 82. The transport vehicle 40 that has entered the travel space S can raise the loading platform 41 above the pair of pallet support parts 82 through the atrium (see Figure 7 (b)). The distance between the two pillars 81 aligned in the X direction is wider than the width of the transport vehicle 40 in the X direction (see Figures 2 and 4). This allows the transport vehicle 40 to pass between the two pillars 81 and enter and exit the travel space S.

The pallet guide portion 83 is disposed close to and above the pallet support portion 82. The pallet guide portion 83 guides the pallet 20 so that the pallet 20 supported by the pallet support portion 82 is positioned. The pallet guide portion 83 is, for example, a guide for guiding the pallet 20. The pallet guide portion 83 is provided on the upper surface 82a of the pallet support portion 82. The pallet guide portion 83 includes four first pallet guide portions 86 that guide the pallet 20 so that the pallet 20 is positioned in the X direction, and four second pallet guide portions 87 that guide the pallet 20 so that the pallet 20 is positioned in the Y direction.

As shown in Figures 2 and 4, the four first pallet guide parts 86 are tapered members having an inclined surface (surface) 86a. The inclined surface 86a is inclined with respect to the Z direction when viewed from the Y direction. The inclined surface 86a is a flat surface that extends along the Y direction and inclines inward (towards the center position C3 of the pallet 20, away from the support 81) as it extends downward when viewed from the Y direction. The inclined surface 86a of the first pallet guide parts 86 is formed of a resin such as nylon.

As shown in FIG. 4, two of the four first pallet guide parts 86 are arranged in an area on one side of the center position C1 in the Y direction of each of a pair of pallet support parts 82. One of the two first pallet guide parts 86 is provided on the upper surface 82a of one pallet support part 82. The other of the two first pallet guide parts 86 is provided on the upper surface 82a of the other pallet support part 82. The two first pallet guide parts 86 are provided facing each other in the X direction. The distance in the X direction between the lower ends of the inclined surfaces 86a of the two first pallet guide parts 86 corresponds to the horizontal width of the pallet 20 in the X direction.

The other two of the four first pallet guide parts 86 are arranged in an area on the other side of the center position C1 in the Y direction of each of the pair of pallet support parts 82. One of the other two first pallet guide parts 86 is provided on the upper surface 82a of one pallet support part 82. The other of the other two first pallet guide parts 86 is provided on the upper surface 82a of the other pallet support part 82. The other two first pallet guide parts 86 are provided facing each other in the X direction. The distance in the X direction between the lower ends of the inclined surfaces 86a of the other two first pallet guide parts 86 corresponds to the horizontal width of the pallet 20 in the X direction.

As shown in Figures 3 and 4, the four second pallet guide parts 87 are tapered members having an inclined surface (surface) 87a. The inclined surface 87a is inclined with respect to the Z direction when viewed from the X direction. The inclined surface 87a is a flat surface that extends along the X direction and inclines inward (towards the center position C1 of the pallet support part 82) as it extends downward when viewed from the X direction. The inclined surface 87a of the second pallet guide parts 87 is formed of a resin such as nylon.

As shown in FIG. 4, two of the four second pallet guide parts 87 are disposed on the upper surface 82a of one of the pallet support parts 82. The two second pallet guide parts 87 are disposed facing each other in the Y direction. The distance in the Y direction between the lower ends of the inclined surfaces 87a of the two second pallet guide parts 87 corresponds to the horizontal width of the pallet 20 in the Y direction.

The other two of the four second pallet guide parts 87 are arranged on the upper surface 82a of the other pallet support part 82. The other two second pallet guide parts 87 are arranged facing each other in the Y direction. The distance in the Y direction between the lower ends of the inclined surfaces 87a of the other two second pallet guide parts 87 corresponds to the horizontal width of the pallet 20 in the Y direction.

As described above, the four first pallet guide parts 86 and the four second pallet guide parts 87 are arranged to correspond to the four corners of the pallet 20 placed on the pallet support part 82. The four first pallet guide parts 86 and the four second pallet guide parts 87 position the pallet 20 in the X direction and the Y direction. For example, when the pallet 20 is placed on the pallet support part 82 from above, it is positioned in the X direction by being guided by the inclined surfaces 86a of the four first pallet guide parts 86, and is positioned in the Y direction by being guided by the inclined surfaces 87a of the four second pallet guide parts 87.

As shown in Figs. 2, 3 and 5, the pair of core support parts 84 is supported by four pillars 81. The pair of core support parts 84 is arranged above the pallet support part 82. The pair of core support parts 84 is arranged to face each other in the X direction. Each of the pair of core support parts 84 has a frame-shaped member 88 extending in the Y direction and a support member 90 provided on the upper surface 88a of the frame-shaped member 88. The frame-shaped member 88 is fixed to the pillar 81. The frame-shaped member 88 is formed by joining two frame bodies whose thickness direction is the Z direction. Each frame body is, for example, a rectangular frame shape and is formed by four square steel pipes (square pipe material). The frame-shaped member 88 may be one frame body or a rectangular plate shape. The frame-shaped member 88 includes a planar upper surface 88a and a lower surface 88b. The upper surfaces 88a are provided to be at the same height as each other in the Z direction and are located on the same horizontal plane. The distance in the X direction between the pair of frame-shaped members 88 (the gap between the pair of frame-shaped members 88) is narrower than the width in the X direction of the core material 10a. The distance in the X direction between the pair of frame-shaped members 88 is wider than the width in the X direction of the roll body 10b. The distance in the X direction between the pair of frame-shaped members 88 is wider than the distance in the X direction between the first receiving member 22A and the second receiving member 22B.

The pair of support members 90 are provided at the center positions of the upper surfaces 88a in the Y direction. The support members 90 have grooves that open upward. The grooves of the support members 90 include an inclined surface (surface) 91 on the inner surface. The inclined surface 91 is inclined with respect to the Z direction when viewed from the X direction. The inclined surface 91 is a plane that extends along the X direction and inclines inward (toward the center position of the core material support section 84) as it moves downward when viewed from the X direction. The inclined surface 91 of the support member 90 is formed of a resin such as nylon. When the core material 10a is placed from above, the pair of support members 90 support the core material 10a from the lower side with the inclined surface 91. When the core material 10a of the roll 10 is placed on the core material support section 84, each inclined surface 91 of the pair of support members 90 guides the core material 10a to be positioned in the Y direction.

The pair of core material guide portions 85 are disposed adjacent to and above the core material support portion 84. The pair of core material guide portions 85 guide the core material 10a so that the position of the core material 10a supported by the core material support portion 84 is determined. The core material guide portion 85 is, for example, a guide that guides the core material 10a. The pair of core material guide portions 85 are provided on the upper surfaces 84a of the pair of core material support portions 84, respectively. The pair of core material guide portions 85 are provided in positions adjacent to the outside of the support member 90 in the X direction.

The core material guide portion 85 is a tapered member having an inclined surface (surface) 85a. The inclined surface 85a is inclined with respect to the Z direction when viewed from the Y direction. The inclined surface 85a is a flat surface that extends along the Y direction and inclines inward (towards the center position C2 of the core material 10a, the side away from the support 81) as it extends downward when viewed from the Y direction. The inclined surface 85a of the core material guide portion 85 is formed of a resin such as nylon.

One of the pair of core material guides 85 is disposed on the upper surface 84a of one of the core material support parts 84. The other of the pair of core material guides 85 is disposed on the upper surface 84a of the other core material support part 84. The pair of core material guides 85 are disposed to face each other in the X direction. The distance in the X direction between the lower ends of the inclined surfaces 85a of the pair of core material guides 85 corresponds to the width of the core material 10a in the X direction. When the core material 10a of the roll 10 is placed on the core material support part 84, each inclined surface 85a of the pair of core material guides 85 guides the core material 10a to position it in the X direction.

The pallet guide section 83 and the core material guide section 85 respectively guide (correct) the pallet 20 and the core material 10a so that the center position C2 of the core material 10a in the X direction coincides with the center position C3 of the pallet 20 in the X direction. For example, the center of the gap between the lower ends of the inclined surfaces 86a of a pair of first pallet guide sections 86 facing each other in the X direction and the center of the gap between the lower ends of the inclined surfaces 85a of a pair of core material guide sections 85 facing each other in the X direction are configured to coincide with each other.

As shown in Figures 2 and 3, in the Z direction, the distance L1 from the upper surface 82a of the pallet support portion 82 to the contact point P of the core material support portion 84 with the core material 10a is greater than the distance L2 from the lower surface 21b of the pallet 20 to the contact point Q of the receiving member 22 with the core material 10a. As a result, when the pallet 20 is transferred to the station device 80, the station device 80 supports the core material 10a and the pallet 20 in a separated state.

In addition, in the Z direction, the distance L1 from the upper surface 82a of the pallet support portion 82 to the contact point P with the core material 10a of the core material support portion 84 is smaller than the sum of the distance L2 and the maximum height H (see FIG. 7 described below) of the upper surface 41a of the loading platform 41 when the loading platform 41 of the transport vehicle 40 is operated in the Z direction. This allows the transport vehicle 40 to transport the pallet 20 while placing the core material 10a on the pallet 20 when the loading platform 41 is moved upward.

The contact point P may be any point that is located at the lowest of the contact points between the core material support portion 84 and the core material 10a when the pallet 20 is transferred to the station device 80. In the first embodiment, the contact point P is located on the inclined surface 91 of the support member 90, and may be located, for example, between the upper end and the lower end, or at the upper end or the lower end. Furthermore, when the inclined surface 91 and the core material 10a are in continuous contact, the contact point P may be any point that is located at the lowest position in the Z direction among the contact areas between the inclined surface 91 and the core material 10a.

The contact point Q may be the point located at the lowest position in the Z direction among the contact points between the receiving member 22 and the core material 10a when the core material 10a is placed on the pallet 20. In the first embodiment, the contact point Q is the contact point between the end 23 of the receiving member 22 and the core material 10a. For example, the contact point Q may be the contact point between the inner surface of the end 23 that forms the V-shaped groove and the core material 10a. For example, when the receiving member 22 and the core material 10a are in continuous contact, the contact point P may be the point located at the lowest position in the Z direction among the contact areas between the receiving member 22 and the core material 10a.

In addition, in the station device 80, as shown in FIG. 2, the space between the pallet support part 82 and the core material support part 84 is open in the Y direction. This makes it possible to transport the pallet 20 into the space between the pallet support part 82 and the core material support part 84 from the Y direction.

Next, referring to Figures 6 and 7, an example of removing a pallet 20 carrying rolls 10 from a rack 50 via a station device 80 will be described.

First, the pallet 20 carrying the roll 10 is transferred from the rack 50 onto the slide fork of the stacker crane 70. Here, the roll 10 is placed on the pallet 20 with the center position C2 in the X direction of the core material 10a shifted to one side in the X direction with respect to the center position C3 in the X direction of the pallet 20, as shown in FIG. 6(a).

Then, the slide fork of the stacker crane 70 carrying the pallet 20 is inserted from the Y direction into the space between the pallet support section 82 and the core support section 84 in the station device 80. This positions the core 10a of the roll 10 above the core support section 84, and positions the roll body 10b of the roll 10 between the pair of core support sections 84 in the X direction.

Next, as shown in FIG. 6(b), the slide fork of the stacker crane 70 is lowered to unload the pallet 20 into the station device 80. Specifically, the slide fork is lowered to separate the roll 10 from the pallet 20 and support it on the core material support part 84, and then the slide fork is lowered to support the pallet 20 on the pallet support part 82. In other words, when unloading using the stacker crane 70, the core material 10a is placed on the upper roll receiver first, and after the core material 10a is separated from the pallet 20, the pallet 20 is placed on the pallet support part 82. Then, the slide fork of the stacker crane 70 is withdrawn from the space between the pallet support part 82 and the core material support part 84 in the station device 80.

At this time, the core material 10a of the roll 10 abuts appropriately against any of the inclined surfaces 85a of the pair of core material guide parts 85 and slides along the inclined surfaces 85a. As a result, the core material 10a is pushed out and moved appropriately in the X direction by the inclined surfaces 85a, and its position in the X direction is positioned at a position corresponding to the space between the pair of core material guide parts 85 (see Figures 2 and 5). In addition, the pallet 20 abuts appropriately against any of the inclined surfaces 86a of the four first pallet guide parts 86 and slides along the inclined surfaces 86a. As a result, the pallet 20 is pushed out and moved appropriately in the X direction by the inclined surfaces 86a, and its position in the X direction is positioned at a position corresponding to the space between the four first pallet guide parts 86 (see Figures 2 and 4). The pallet 20 abuts appropriately against any of the inclined surfaces 87a of the four second pallet guide parts 87 and slides along the inclined surfaces 87a. As a result, the pallet 20 is pushed out and moved appropriately in the Y direction by the inclined surface 87a, and its position in the Y direction is positioned at a position corresponding to the space between the four second pallet guide parts 87 (see Figures 3 and 4). As a result, the center position C2 of the core material 10a in the X direction and the center position C3 of the pallet 20 in the X and Y directions are corrected (centered) so that they coincide in the X direction.

As shown in FIG. 7(a), the transport vehicle 40 enters the travel space S from the Y direction, and is stopped within the travel space S so that the loading platform 41 is positioned below the pallet 20. At this time, the transport vehicle 40 is stopped so that the center position in the X direction of the loading platform 41 of the transport vehicle 40 corresponds to the center position C2 in the X direction of the pallet 20.

Finally, as shown in FIG. 7(b), the loading platform 41 of the transport vehicle 40 is raised above the pair of pallet support parts 82 through the gap between them, and the pallet 20 is lifted (loaded from below). As a result, the core material 10a of the roll 10 is supported again by the receiving member 22 of the pallet 20, and the pallet 20 is lifted by the loading platform 41 while the core material 10a is separated from the core material support parts 84. As a result, the transport vehicle 40 lifts the pallet 20 on which the roll 10 is loaded, with the center position C2 of the core material 10a in the X direction and the center position C3 of the pallet 20 in the X direction coinciding in the X direction. That is, the transport vehicle 40 loads the pallet 20 with the core material 10a positioned relative to the pallet 20 (with the roll 10 loaded on the pallet 20 based on their respective center positions (centers)). As described above, when the transport vehicle 40 loads the pallet 20, the pallet 20 and the roll 10 are scooped up from below in this order, so that the pallet 20 and the core material 10a are centered. The transport vehicle 40 raises the platform 41 carrying the pallet 20 to a position between the pallet support section 82 and the core material support section 84 in the station device 80. The transport vehicle 40 then travels to the manufacturing device and supplies the pallet 20 carrying the roll 10 to the manufacturing device.

The effects of the automated warehouse system 1 and station device 80 according to the first embodiment will be described below. In general, when a pallet 20 carrying a roll 10 is transferred, the roll 10 may be misaligned with respect to the pallet 20. For example, when a worker in a factory places a roll 10 brought into a factory on the pallet 20, the roll 10 may be misaligned with respect to the pallet 20, and the pallet 20 and the core material 10a may not be accurately centered. In this case, in the station device according to the conventional technology, the roll 10 and the pallet 20 are positioned together, so even if the roll 10 is misaligned with respect to the pallet 20, the misalignment is not eliminated. Therefore, when the roll 10 is supplied to the manufacturing device by the transport vehicle 40, there is a risk that the roll 10 may interfere with the manufacturing device due to the severe competition.

In contrast, the station device 80 of the automated warehouse system 1 according to the first embodiment is equipped with a mechanism (centering mechanism) that centers the roll 10 and the pallet 20 when the pallet 20 is released from the automated warehouse 30. Thus, when the station device 80 transfers the pallet 20 carrying the roll 10, it can support the core material 10a of the roll 10 and the pallet 20 in a separated state, and can position the supported pallet 20 and core material 10a by the pallet guide unit 83 and the core material guide unit 85, respectively. As a result, it becomes possible to position the pallet 20 and the roll 10, respectively.

For example, when the pallet 20 is lifted from below in the Z direction by the stacker crane 70 and the transport vehicle 40, the core material 10a can be positioned in the X and Y directions relative to the pallet 20, and the pallet 20 can be transferred in a state where the center position C2 of the core material 10a in the X direction and the center position C3 of the pallet 20 in the X direction are aligned (centered). Therefore, when the roll 10 and pallet 20 are supplied to a manufacturing device in a factory, the roll 10 and pallet 20 can be prevented from interfering with the device. As a result, they can be handled without interfering with the manufacturing device.

In the station device 80, the pallet guide section 83 may be provided adjacent to and above the pallet support section 82, and the core material guide section 85 may be provided adjacent to and above the core material support section 84. In this case, the above-mentioned effect of enabling the positioning of the pallet 20 and the roll 10 can be specifically realized. In addition, when the pallet 20 is transferred to the station device 80, the core material 10a is supported by the core material support section 84 immediately after being positioned by the core material guide section 85. Then, the pallet 20 is supported by the pallet support section 82 immediately after being positioned by the pallet guide section 83. This makes it possible to reduce the amount of movement of the pallet 20 in the vertical direction when the pallet 20 is transferred to the station device 80.

In the station device 80, a travel space S in which the transport vehicle 40 can travel is provided below the pallet support section 82. In this case, the transport vehicle 40 can enter the station device 80 using the travel space S. Specifically, the transport vehicle 40 can enter below the pallet support section 82 and the core material support section 84. This allows the transport vehicle 40 to place the roll 10 on the pallet 20 while positioning the pallet 20 and the core material 10a of the roll 10, respectively, when the transport vehicle 40 lifts the pallet 20 and the roll 10 from below in the Z direction. In other words, the pallet 20 and the core material 10a of the roll 10 can be positioned by transferring the pallet 20 and the roll 10 from the automated warehouse 30 to the transport vehicle 40.

In the station device 80, the inclined surfaces 86a, 87a of the pallet guide section 83 and the inclined surface 85a of the core material guide section 85 are formed of a resin such as nylon. In this case, it is possible to suppress the generation of metal powder due to wear of the pallet guide section 83 and the core material guide section 85. Specifically, the generation of metal powder due to the pallet 20 rubbing against the pallet guide section 83 is suppressed, and the generation of metal powder due to the core material 10a rubbing against the core material guide section 85 is suppressed. This makes it possible to suppress problems caused by the metal powder in the device to which the roll 10 is supplied.

In the station device 80, the pallet guide unit 83 and the core material guide unit 85 respectively guide the pallet 20 and the core material 10a so that the center position C2 of the core material 10a in the X direction coincides with the center position C3 of the pallet 20 in the X direction. In this case, it is possible to center the pallet 20 and the core material 10a in the X direction. As a result, it is possible to more reliably prevent the roll 10 and the pallet 20 from interfering with the device to which the roll 10 is supplied.

The automated warehouse system 1 includes a station device 80, a rack 50 on which the pallets 20 are stored, a stacker crane 70 that travels along a traveling rail 71 and transfers the pallets 20, and a controller 100 that controls the stacker crane 70. Because the automated warehouse system 1 includes the station device 80, it is possible to realize the effect of enabling the positioning of the pallets 20 and the rolls 10. Specifically, in the automated warehouse system 1, the stacker crane 70 can place the pallet 20 on the station device 80. This enables the positioning of the pallets 20 and the rolls 10.

In the automated warehouse system 1, the station device 80 is adjacent to the traveling rail 71, and when the pallet 20 is to be removed, the controller 100 executes control to control the stacker crane 70 to transfer the pallet 20 to the station device 80. In this case, when the pallet 20 is removed, the pallet 20 can be transferred to the station device 80 and each can be positioned. Specifically, when the pallet 20 carrying the rolls 10 is removed from the rack 50, the stacker crane 70 transfers the pallet 20 from the rack 50 to the station device 80. This makes it possible to position the pallet 20 and the rolls 10.

[Second embodiment]
Next, a second embodiment will be described. In the description of this embodiment, the points similar to those of the first embodiment will be omitted, and differences will be described.

As shown in FIG. 8, the automated warehouse system 101 according to the second embodiment differs from the first embodiment in that a station device 80 constitutes an input station in the automated warehouse 30 instead of the conveyor 60 (see FIG. 1). The automated warehouse system 101 differs from the first embodiment in that another station device 180 constitutes an output station in the automated warehouse 30 instead of the station device 80 (see FIG. 1). The station device 80 is provided outside the rack 50. The other station device 180 is provided inside the rack 50.

In the automated warehouse system 101 according to the second embodiment, the automated warehouse 30 stores the pallet 20 transferred to the station device 80 by the transport vehicle 40 in the rack 50 using the stacker crane 70. Then, the automated warehouse 30 transfers the pallet 20 stored in the rack 50 to another station device 180 using the stacker crane 70. The automated warehouse 40 lifts the pallet 20 transferred to the other station device 180 and transports it to a manufacturing device in the factory. At this time, the station device 80 is provided adjacent to the running rail 71 outside the rack 50. Thus, in the second embodiment, the station device 80 is a mechanism that performs centering of the roll 10 and the pallet 20 in the X direction when the pallet 20 is stored in the automated warehouse 30.

The other station device 180 is provided inside the rack 50 and is adjacent to the running rail 71. The other station device 180 has the pallet 20 transferred thereto and supports the underside 21b of the pallet 20 without supporting the core material 10a. The other station device 180 may be any ordinary station device to which the pallet 20 can be transferred. For example, the other station device 180 may be a station device that does not have a core material support portion 84 and a core material guide portion 85 compared to the station device 80, or may be any other station device other than those described above.

When a pallet 20 is received, the controller 100 controls the transport vehicle 40 to transfer the pallet 20 to the station device 80. The controller 100 controls the stacker crane 70 to store the pallet 20 transferred to the station device 80 in the rack 50. When a pallet 20 is removed, if the pallet 20 has been transferred to the station device 80 at least once (has a transfer history), the controller 100 controls the stacker crane 70 to transfer the pallet 20 to another station device 180. The controller 100 controls the transport vehicle 40 to transport the pallet 20 from the other station device 180 to a manufacturing device in the factory.

The controller 100 acquires the transfer history of the pallets 20. As an example, a barcode that identifies each pallet 20 is provided for each pallet 20. When a pallet 20 is transferred to the station device 80, the barcode is read by a barcode reader or the like provided in the station device 80, and the read information is output to the controller 100. This allows the controller 100 to determine whether each pallet 20 has been transferred to the station device 80 at least once based on the received information. Note that the method by which the controller 100 acquires the transfer history of the pallets 20 is not particularly limited, and various known methods can be used.

In the automated warehouse system 101, when a pallet 20 is removed from the rack 50, if the pallet 20 has been transferred to a station device 80 at least once, the pallet 20 can be transferred to another station device 180 and removed from the rack 50 without repositioning the rolls 10 because the pallet 20 and rolls 10 have already been positioned before the pallet 20 is removed from the rack 50. This eliminates the need to position the pallet 20 using the station device 80 when removing the pallet 20 from the rack 50. As a result, the time required to remove the pallet 20 from the rack 50 can be reduced.

Specifically, in the automated warehouse system 101, when a pallet 20 is stored, the controller 100 may execute control to transfer the pallet 20 to a station device 80, and when the pallet 20 is removed, the controller 100 may execute control to control the stacker crane 70 to transfer the pallet 20 to another station device 180. In this case, when the pallet 20 is stored, the pallet 20 can be transferred to the station device 80 and positioned. This eliminates the need to position the pallet 20 using the station device 80 when removing it from the rack 50. As a result, the time required to remove the pallet 20 from the rack 50 can be shortened.

The automated warehouse system 101 according to the second embodiment also provides the same effects as the first embodiment.

[Third embodiment]
Next, a third embodiment will be described. In the description of this embodiment, the points similar to those of the first embodiment will be omitted, and only the points that are different will be described. As shown in Fig. 9, an automated warehouse system 201 according to the third embodiment differs from the first embodiment in that another station device 180, separate from the station device 80, is provided inside the rack 50, forming a shipping station. In the automated warehouse system 201, the station device 80 is provided in a rack 50 separate from the rack 50 in which the other station device 180 is provided.

In the automated warehouse system 201 according to the third embodiment, the automated warehouse 30 transfers the pallet 20 from the conveyor 60 to the station device 80, and then stores the pallet 20 in the rack 50. The automated warehouse 30 then removes the pallet 20 from the rack 50 in the same manner as in the second embodiment. At this time, since the pallet 20 has been transferred once to the station device 80 when it was stored in the rack 50, the controller 100 executes control to transfer the pallet 20 to another station device 180 when removing the pallet 20. Note that the controller 100 acquires the transfer history of the pallet 20 in the same manner as in the second embodiment.

In the automated warehouse system 301, the pallet 20 is transferred to the station device 80 at least once after it is transported by the conveyor 60 and before it is removed from the rack 50. This allows the pallet 20 and the roll 10 to be positioned at any time after it is transported by the conveyor 60 and before it is removed from the rack 50.

The automated warehouse system 201 according to the third embodiment also provides the same effects as the first embodiment.

Note that the station device 80 in the third embodiment may be provided in at least one of the two racks 50. For example, as shown in FIG. 10, in an automated warehouse system 301 according to a modified example of the third embodiment, the station device 80 may be provided in a rack 50 in which another station device 180 is provided.

[Fourth embodiment]
Next, a fourth embodiment will be described. In the description of this embodiment, the same points as in the first embodiment will be omitted, and differences will be described. As shown in FIG. 11, an automated warehouse system 401 according to the fourth embodiment differs from the first embodiment in that another station device 180 constitutes a retrieval station in the automated warehouse 30 and that a station device 80 is provided outside the rack 50. The other station device 180 is provided inside the rack 50 instead of the station device 80 in FIG. 1. In the fourth embodiment, the pallet 20 is transferred to the station device 80 provided outside the rack 50 at least once before being transferred to the source of the conveyor 60.

In the automated warehouse system 401 according to the fourth embodiment, the automated warehouse 30 transfers the pallet 20 to the station device 80 by the transport vehicle 40. The automated warehouse 30 transfers the pallet 20 from the station device 80 to the source of the conveyor 60 by the automated guided vehicle 40, a robot arm, a ceiling crane, or the like. The automated warehouse 30 stores the pallet 20 transported by the conveyor 60 in the rack 50 by the stacker crane 70. Then, the automated warehouse 30 takes the pallet 20 out of the rack 50 in the same manner as in the second embodiment. At this time, since the pallet 20 has a history of having been transferred to the station device 80 in the past, the controller 100 executes control to transfer the pallet 20 to another station device 180 when taking out the pallet 20. The controller 100 acquires the transfer history of the pallet 20 in the same manner as in the second embodiment.

In the automated warehouse system 401, the pallet 20 is placed on the station device 80 at least once between the time it arrives at the factory and the time it is stored in the rack 50. In this case, in the automated warehouse system 401, the pallet 20 and the roll 10 are each positioned before the pallet 20 is removed from the rack 50, so that the time required to remove the pallet 20 from the rack 50 can be shortened.

The automated warehouse system 401 according to the fourth embodiment also provides the same effects as the first embodiment.

The first to fourth embodiments have been described above, but one aspect of the present invention is not limited to the above embodiments, and various modifications are possible without departing from the spirit of the invention.

In the first embodiment, the station device 80 is provided inside the rack 50, but the outgoing station may be configured outside the rack 50. In this case, too, when the pallet 20 is to be outgoing, the controller 100 controls the stacker crane 70 to transfer the pallet 20 from the rack 50 to the station device 80.

In the fourth embodiment, the station device 80 was located at the origin of the conveyor 60, but it may be located on the transport path of the pallet 20 until the pallet 20 is stored in the rack 50. For example, in the automated warehouse system 201, the station device 80 may be located at the entrance of a factory, and the pallet 20 may be transferred to the station device 80 immediately after the roll 10 is placed on the pallet 20.

In the third embodiment, the pallet 20 is transferred from the conveyor 60 to the station device 80, and then stored in the rack 50. However, it is sufficient that the pallet 20 is transferred to the station device 80 before it is removed from the rack 50. For example, when removing the pallet 20 from the automated warehouse 30, the pallet 20 may be transferred to the station device 80, and then the stacker crane 70 may be used to transfer the pallet 20 to another station device 180 for removal from the warehouse.

In the first to fourth embodiments described above, the pallet 20 is transferred to the station device 80 at least once before the pallet 20 is removed from the rack 50, but this is not limited to the above. For example, after the pallet 20 is removed from the rack 50, the pallet 20 may be placed on the station device 80 at least once when the pallet 20 is transported from the rack 50 to a manufacturing device in a factory by the transport vehicle 40.

In the first to fourth embodiments described above, the four first pallet guide parts 86 and the four second pallet guide parts 87 need only be able to position the pallet 20 in the X and Y directions. For example, the four first pallet guide parts 86 may be a plurality of rollers capable of positioning the pallet 20 in the X direction. The four second pallet guide parts 87 may be a plurality of rollers capable of positioning the pallet 20 in the Y direction. The rollers may be configured to be rotatable, for example, using bearings or the like, and may guide and position the pallet 20 with their peripheral surfaces.

In addition, for example, since the station device 80 only requires that the pallet 20 be positioned in the X and Y directions, a pusher capable of positioning the pallet 20 in the X direction may be provided in place of the four first pallet guide parts 86, and a pusher capable of positioning the pallet 20 in the Y direction may be provided in place of the four second pallet guide parts 87. The pusher is, for example, a cylinder or the like configured to push the pallet 20 inward (towards the center position C3 of the pallet 20, away from the support 81).

In the first to fourth embodiments described above, the pair of core material guide parts 85 need only be able to position the core material 10a in the X direction. For example, the pair of core material guide parts 85 may be a plurality of rollers that can position the core material 10a in the X direction. Also, for example, in the station device 80, since it is only necessary to be able to position the core material 10a in the X direction, a pusher that can position the core material 10a in the X direction may be provided instead of the pair of core material guide parts 85.

In the first to fourth embodiments described above, the lower surface 21b may be a location that comes into contact with the upper surface 82a of the pallet support part 82 when the pallet 20 is supported by the pallet support part 82. For example, when the pallet 20 is supported by the pallet support part 82 at a plurality of protruding parts that protrude downward from the pallet 20 in the Z direction, the lower surface 21b may be each of the contact points with the upper surface 82a of the pallet support part 82 at the plurality of protruding parts.

In the first to fourth embodiments, when the pallet 20 is transferred to the station device 80, a stacker crane 70 or a transport vehicle 40 is used, but this is not limited to the above. The pallet 20 may be transferred to the station device 80 by hand, for example, by a worker in a factory, or by other means other than those described above. In addition, if the pair of support members 90 are provided with a gap wider than the width of the pallet 20 in the X direction, the pallet 20 may be transferred from above to the station device 80 by, for example, a ceiling crane in a factory.

In the above embodiment, for convenience of explanation, the X direction and the Y direction are used for explanation, but the direction of the station device 80 is not particularly limited. For example, if the station device 80 in the above embodiment is rotated 90 degrees around the vertical direction, the X direction in the description of the above embodiment corresponds to the Y direction, and the Y direction in the description of the above embodiment corresponds to the X direction.

The components in the above embodiments and modifications are not limited to the materials and shapes described above, and various materials and shapes can be applied. The components in the above embodiments or modifications can be applied to the components in other embodiments or modifications as desired. Parts of the components in the above embodiments or modifications can be omitted as appropriate without departing from the gist of one aspect of the present invention.
