Description

[Technical field]

[0001] The present invention relates to a work station apparatus, and more particularly to a work station apparatus that is arranged near an automated warehouse and allows workers to perform picking operations and the like. [Background technology]

[0002] A stacker crane or shuttle cart in an automated warehouse transports packages to store and retrieve them. A picking station may be provided behind the racks in the automated warehouse. In this case, the stacker crane or shuttle cart retrieves the packages to the picking station. Then, a worker picks items from within the packages at the picking station.

[0003] A sorting system and a sorting method for a facility in which work stations are arranged in an automated warehouse are known (see Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] WO 2012 / 32865 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above case, since the stacker crane and shuttle cart are a source of danger to workers, it is preferable that the workers cannot approach them. However, providing a conveyor between the stacker crane or shuttle cart and the worker to ensure sufficient distance, or providing a light curtain to detect the approach of the worker, etc., would be costly.

[0006] An object of the present invention is to provide a work station apparatus in which the work location of an operator is located away from the loading / unloading apparatus. [Means for solving the problem]

[0007] In the following, several aspects will be described as means for solving the problems. These aspects can be arbitrarily combined as necessary. According to one aspect of the present invention, a work station apparatus is disposed near an automated warehouse having a rack and an input / output device. The work station apparatus includes a pusher device and a pull-out table. The pusher device is disposed adjacent to the rack and moves the load by pushing it from the rack side to the work area located away from the rack. The pull-out table is disposed on the working area side of the pusher device, and has an upper surface on which an operator can pull out and place the baggage pushed out by the pusher device toward himself or herself. The storage / retrieval device is a device for storing and retrieving luggage into and from the rack.

[0008] In this device, a pusher device and a drawer table are provided between the worker in the work area and the loading / unloading device of the automated warehouse. In other words, by providing the pusher device and the drawer table, the worker can be kept away from the loading / unloading device of the automated warehouse. In this device, the pusher device allows the worker to easily pull the baggage out towards the front. The reason is that, unlike a conveyor, when using a pusher device, the resistance generated when the baggage moves can be set small, so less force is required to pull it out. In this device, the pull-out table allows the worker to work at a position away from the pusher device.

[0009] The pusher device may have a swivel belt extending between the rack and the pull-out table, and a pusher provided outside the swivel belt and capable of pushing luggage at an upper position. In this device, when the rotating belt is driven, the pushing part moves and pushes the luggage. In this device, the pushing section can push the luggage in both directions in the conveying direction, facilitating the loading and unloading of luggage.

[0010] The work station apparatus may further include a controller operable to control the pusher apparatus. The controller is The pusher device is moved to a push end position at the time of delivery to push the baggage to the removal position, The pusher may be maintained in the retrieval end position until the worker next pulls out the item onto the pull-out table and subsequently returns the item to the removal position. In this device, when the worker returns the item to the removal position, the item hits the pushing section and is positioned accordingly, thus simplifying the worker's task of returning the item.

[0011] The controller is By driving the swivel belt, the pushing unit may be moved from the end position for pushing the luggage when it is removed from the warehouse, passing below, to an upper position on the working area side, and then the pushing unit may be caused to push the luggage toward the loading / unloading device. In this device, luggage placed at the end of pushing at the time of retrieval is automatically returned to the loading / unloading device side by the pusher device.

[0012] The controller is When the next package is to be removed after the package has been removed from the drawer table, the pusher is placed in the lower position in advance. When storing a package and then storing the next package, the pushing unit may be positioned in the upper position in advance. As described above, when consecutive deliveries are made, the pushing unit is already in the lower position, so that the packages can be put into the pusher device quickly. Also, when consecutive deliveries are made, the pushing unit is already in the upper position, so that the worker can easily return the packages to the take-out position. The pushing section can start pushing the next load quickly.

[0013] The drawer table may have a flat first portion on the loading / unloading device side, and a second portion rotatably mounted on the first portion and movable between a flat position and an upright position rotated upward. In this device, by moving the second part of the drawer table to the upright position, the worker can approach the pusher device, thereby improving workability. Also, for example, when the worker pulls out a package onto the drawer table, the worker can stop the package by hitting it against the second part by moving the second part of the drawer table to the upright position. Furthermore, for example, when an operator places an external item on the drawer table, the second portion of the drawer table can be moved to the flat posture position, making it easier for the operator to place the item on the drawer table. Effect of the Invention

[0014] In the work station apparatus according to the present invention, the work location of the worker can be located away from the loading / unloading device. [Brief description of the drawings]

[0016] 1. First embodiment (1) Overview of the automated warehouse An automated warehouse 100 according to a first embodiment will be described with reference to Figures 1 and 2. Figure 1 is a schematic side view of the automated warehouse according to the first embodiment. Figure 2 is a schematic plan view of the automated warehouse. In the following description, the left-right direction in Figure 1 is referred to as a first direction (arrow Y), the depth direction of the paper in Figure 1 is referred to as a second direction (arrow X), and the up-down direction in Figure 1 is the vertical direction (arrow Z).

[0017] The automated warehouse 100 has a plurality of shelves 21 and is a system capable of storing goods on each shelf 21 and retrieving goods stored on each shelf 21. The automated warehouse 100 includes a rack 1, a plurality of transport vehicles 3, an entrance station 7, an outgoing station 9, an entrance lifting device 11, and an outgoing lifting device 13.

[0018] A pair of racks 1 and transport vehicles 3 constitute a unit 4, and the automated warehouse 100 has a plurality of units 4. The numbers of the units 4 may be expressed as a "system," and the units 4 are a type of automated warehouse unit. In unit 4, the luggage is carried in from an input conveyor (not shown) to a storage station 7. Also, in unit 4, the luggage is carried out from a delivery station 9 to an output conveyor (not shown). The output conveyor is destined for a sorting area where the luggage is collected according to its shipping destination and shipped by truck or the like.

[0019] (2) Rack Each shelf 21 of the rack 1 extends long in the first direction and has a plurality of openings 22. Each opening 22 is a unit of shelf on which a package W is placed, and has the same length in the first direction. The shelves 21 are arranged on both sides in the second direction with respect to the transport vehicle 3 and the rails 5 (described later).

[0020] A plurality of packages can be stored in each opening 22. The openings 22 may be separate or integrally formed. In other words, a single shelf board constituting the shelf level 21 may be divided to form a plurality of openings 22 in the shelf level 21. The baggage W is a case, a tray, a cardboard box, a collapsible container, etc., and contains the baggage.

[0021] (3) Transport vehicle The multiple transport vehicles 3 (an example of an entry / exit device) are each capable of traveling along a first direction at a height corresponding to each shelf level 21. Specifically, rails 5 extending linearly in the first direction are laid at a height corresponding to each shelf level 21, and the transport vehicles 3 can travel back and forth in the first direction on the rails 5. In other words, the transport vehicles 3 are shuttle carts. The transport vehicle 3 has a transfer device 15 and is capable of transferring the cargo W in the second direction between the frontage 22 of the corresponding shelf 21. The transfer device 15 is, for example, a rear hook type. However, the type of the transfer device is not limited.

[0022] (4) Lifting device The storage lifting device 11 is disposed between the rack 1 and the storage station 7, and includes a lifting mechanism (not shown) and a lifting platform 53. The lifting mechanism is a known technology, and raises and lowers the lifting platform 53 in the vertical direction along a support 55. The lifting platform 53 includes a lifting platform conveyor 57 for transferring the cargo W between the storage station 7 and the shelf 21. In addition, each shelf 21 is provided with a storage conveyor 23 at a portion adjacent to the storage lifting device 11 in the first direction. Therefore, the cargo W is delivered by the two conveyors operating in conjunction with each other. The storage conveyor 23 functions as a buffer conveyor for storing cargo.

[0023] The outgoing lifting device 13 is provided on the same side as the incoming lifting device 11 with respect to the rack 1 in the first direction. The outgoing lifting device 13 is disposed between the rack 1 and the outgoing station 9, and has a lifting mechanism (not shown) and a lifting platform 63. The lifting mechanism is a known technology, and raises and lowers the lifting platform 63 in the vertical direction along a support (not shown). The lifting platform 63 has a lifting platform conveyor 67 that transfers the baggage W between the outgoing station 9 and the shelf 21. In addition, each shelf 21 is provided with an outgoing conveyor 25 at a portion adjacent to the outgoing lifting device 13 in the first direction. Therefore, the two conveyors operate in conjunction with each other to transfer the baggage W. The outgoing conveyor 25 functions as a buffer conveyor for storing the baggage.

[0024] (5) Receiving station and leaving station The storing station 7 is disposed on one side in the first direction of the rack 1. The storing station 7 receives the baggage W to be stored in the rack 1 from a carry-in conveyor (not shown). The storing station 7 has a station conveyor 7a.

[0025] The outgoing station 9 is disposed on the same side as the incoming station 7 in the first direction with respect to the rack 1. The outgoing station 9 receives the baggage W taken out from the rack 1. The outgoing station 9 has a station conveyor 9a. The locations and numbers of the entrance and exit stations are not particularly limited.

[0026] (6) Configuration of Work Station Equipment A work station 101 (an example of a work station) will be described with reference to Fig. 2 and Fig. 5 to Fig. 17. Fig. 5 to Fig. 10 are schematic side views of the work station. Fig. 11 to Fig. 17 are schematic plan views of the work station. The work station device 101 is a facility where goods are picked from the luggage W that is to be delivered to the outside from the automated warehouse 100. Specifically, the luggage W is supplied to the work station device 101 by a transfer device 15 of the transport vehicle 3. In addition, the transfer device 15 can return the luggage W on the work station device 101 to the automated warehouse 100.

[0027] The work station device 101 is disposed near the automated warehouse 100. Specifically, the work station device 101 is disposed on the rear side of the rack 1. "The rear side of the rack 1" means the side opposite the internal passage of the rack 1, that is, the external side of the rack 1. However, a part of the work station device 101 is disposed inside the rack 1 (described later).

[0028] 2 and 5, the work station device 101 includes a pusher device 102 and a drawer table 103 (an example of a drawer table). In this embodiment, there are two pusher devices 102 arranged at intervals from each other in the first direction, and there are also two drawer tables 103 arranged at intervals from each other in the first direction. A work area A is provided at a position away from the rack 1 in the first direction, more specifically, on the opposite side of the drawer table 103 from the rack 1. The work area A is an area where a worker O works on packages.

[0029] The pusher device 102 is disposed adjacent to the rack 1, specifically, on the rear side of the rack 1, with a portion of the pusher device 102 disposed inside the rack 1 and the remainder disposed outside the rack 1. The pusher device 102 moves the luggage W between the rack 1 and the work area A by pushing it in a second direction (described later). The drawer table 103 is disposed on the working area A side of the pusher device 102, and has an upper surface 103a on which the worker O can draw out and place the baggage W pushed out by the pusher device 102.

[0030] As described above, the pusher device 102 and the drawer table 103 are provided between the worker O in the work area A in the second direction and the transport vehicle 3 of the automated warehouse 100. In other words, by providing the pusher device 102 and the drawer table 103 side by side in the second direction, the worker O can be kept away from the transport vehicle 3 of the automated warehouse 100. Furthermore, as described above, by using the pusher device 102, the worker O can easily pull the baggage W forward. The reason for this is that, unlike a conveyor, when using the pusher device 102, the resistance acting on the baggage W from the sliding surface (for example, the upper surface of the support base 113 described later) can be set small, so that the force required for the worker O to pull out the baggage W is small.

[0031] (7) Detailed description of the pusher device The pusher device 102 has a swivel belt 109 extending between the rack 1 and the drawer table 103, and a pusher arm 111 that is provided on the outside of the swivel belt 109 and can push the luggage W at an upper position. In this case, the pusher arm 111 can push the luggage W to both sides in the second direction, making it easy to store and retrieve the luggage W. Note that the swivel belt 109 "extending between the rack 1 and the drawer table 103" means that the swivel belt 109 extends in the first direction and has a structure and arrangement that allows the luggage W to be transported between the rack 1 side and the drawer table 103.

[0032] The pusher device 102 further has a support table 113 on which the luggage W can slide, as shown in FIG. 11. The support table 113 may have a flat upper surface or a roller conveyor. The support table 113 has a placement position 113a on the rack 1 side and a removal position 113b on the work area A side. In this embodiment, the placement position 113a and the removal position 113b partially overlap, but they may be completely separated. Note that the pusher arm 111 is located higher than the upper surface of the support table 113 in the upper position.

[0033] As shown in FIG. 11, the revolving belt 109 is a pair of members arranged on both outer sides of the support base 113 in the first direction. The pusher arm 111 is a cylindrical member, and both ends are connected to a pair of swivel belts 109. The pusher arm 111 is rotatable about its axial center. Therefore, when the pusher arm 111 comes into contact with the baggage W, excessive force is unlikely to be applied to the baggage W. The pusher device 102 includes a motor for driving the rotating belt 109, a reduction mechanism, a pulley, and the like, which are not shown.

[0034] When the pair of swivel belts 109 are driven, the pusher arm 111 moves in the second direction above and below the pair of swivel belts 109 as the pair of swivel belts 109 rotate. That is, the pusher arm 111 can be located at an upper position and a lower position of the pair of swivel belts 109. The pusher arm 111 can move to the upper position, which is the start position of pushing when leaving the warehouse (the end position of the swivel belt 109 on the transport vehicle 3 side, where it is close to or abuts the side of the luggage W at the loading position 113a on the transport vehicle 3 side, see Figure 6), the end position of pushing when leaving the warehouse (the intermediate position in the movement direction, specifically, the position where it is close to or abuts the side of the luggage W at the removal position 113b on the transport vehicle 3 side, see Figure 7), the start position of pushing when entering the warehouse (the end position of the swivel belt 109 on the work area A side, where it is close to or abuts the side of the luggage W at the removal position 113b on the work area A side, see Figure 10), and the end position of pushing when entering the warehouse (the intermediate position in the conveying direction, specifically, the position where it is close to or abuts the side of the luggage W at the loading position 113a on the work area A side). The pusher arm 111 can move to a lower first position (a position below the placement position 113a, see FIG. 5) and a lower second position (a position below the removal position 113b) as the lower position.

[0035] (8) Control configuration of the work station device The control configuration of the work station apparatus 101 will be described with reference to Fig. 3. Fig. 3 is a block diagram showing the control configuration of the work station apparatus 101. The work station apparatus 101 has a controller 51. The controller 51 is a computer system having a processor (e.g., a CPU), a storage device (e.g., a ROM, a RAM, a HDD, an SSD, etc.), and various interfaces (e.g., an A / D converter, a D / A converter, a communication interface, etc.) The controller 51 performs various control operations by executing a program stored in a storage unit (corresponding to a part or all of the storage area of ​​the storage device).

[0036] The controller 51 may be configured with a single processor, or may be configured with multiple independent processors for each control. A part or all of the functions of each element of the controller 51 may be realized as a program executable by a computer system constituting the controller. In addition, a part of the functions of each element of the controller 51 may be configured by a custom IC.

[0037] The controller 51 is connected to the pusher device 102 and the display device 71 . A load sensor 73 is connected to the controller 51. The load sensor 73 is a sensor that detects that a load W is placed on the support base 113. Although not shown, sensors for detecting the size, shape and position of the luggage W, sensors and switches for detecting the state of each device, and an information input device are connected to the controller 51.

[0038] (9) Control operation of work station equipment The control operation of the work station 101 will be described with reference to Fig. 4. Fig. 4 is a flow chart showing the control operation of the work station. The control flow charts described below are merely examples, and each step may be omitted or replaced as necessary. In addition, a plurality of steps may be executed simultaneously, or some or all of the steps may be executed in an overlapping manner. Furthermore, each block in the control flowchart is not limited to a single control operation, but can be replaced with a plurality of control operations represented by a plurality of blocks. The operation of each device is the result of commands from the controller 51 to each device, and these are represented by each step of the software application.

[0039] The actions (storing, retrieving, picking, etc.) performed by the worker O are instructed by a display device 71 (FIG. 3). In step S1, it is determined whether an operation of retrieval or retrieval is to be performed. Specifically, the controller 51 makes the above determination based on a command from a higher-level controller (not shown). If it is retrieval, the process proceeds to step S2, and if it is retrieval, the process proceeds to step S5.

[0040] (9-1) Exit operation In step S2, the pusher arm 111 is moved to the lower first position as shown in Figures 5 and 11. Specifically, the controller 51 causes the pusher device 102 to perform the above-mentioned operations. This action is performed, for example, if the previous action was removal from the warehouse. When the pusher arm 111 is already in the lower first position, the above operation is omitted.

[0041] In step S3, the process waits for the luggage W to be placed on the placement position 113a of the support platform 113. Specifically, the controller 51 executes the above-mentioned determination based on a signal from the luggage presence sensor 73. The luggage W is transferred by the transfer device 15.

[0042] In step S4, the pusher arm 111 moves to the outgoing pushing start position as shown in Figures 6 and 12, and then moves to the outgoing pushing end position as shown in Figures 7 and 13, thereby moving the luggage W to the removal position 113b of the support platform 113. Specifically, the controller 51 causes the pusher device 102 to execute the above operation. This allows the worker O to pull out the luggage W to the working position of the pull-out table 103 as shown in Figures 8 and 14. After that, the process returns to step S1. Next, the worker O performs work on the package W. Specifically, the worker O picks up products (not shown) from the package W and transfers them to another container. As mentioned in step S2, in the case of continuous unloading (when the next luggage is unloaded after the worker O removes the luggage W), the pusher arm 111 is placed in the lower position before the transfer device 15 puts the luggage W into the pusher device 102. As a result, the luggage W can be quickly put into the pusher device 102.

[0043] (9-2) Warehousing operation In step S5, the pusher arm 111 is moved to a push end position for taking out the goods (an example of an upper position). Specifically, the controller 51 causes the pusher device 102 to execute the above-mentioned operation. This operation is performed, for example, when the previous operation was taking in the goods. If the pusher arm 111 is already in the exit push end position, the above operation is omitted. Also, the upper position is not limited to the exit push end position.

[0044] In step S6, the process waits for the luggage W to be placed at the removal position 113b of the support platform 113. Specifically, as shown in Figs. 9, 14 and 15, when the worker O pushes the luggage W to the removal position 113b, the controller 51 executes the above-mentioned judgment based on a signal from the presence sensor 73. In this way, when the worker O returns the luggage W to the removal position 113b, the luggage W is positioned by hitting the pusher arm 111 that is at the removal-time pushing end position. This simplifies the work of the worker O returning the luggage W.

[0045] In step S7, the pusher arm 111 moves from the unloading end position to the loading start position as shown in Figs. 10 and 16, passing below, and then to the loading end position as shown in Fig. 17, thereby pushing the luggage W to the placement position 113a. Specifically, the controller 51 causes the pusher device 102 to drive the swivel belt 109 to perform the above operation. After that, the process returns to step S1. The luggage W is taken into the transport vehicle 3 by the transfer device 15. As mentioned in step S5, in the case of successive storage (when a package W is stored and then the next package W is stored), the pusher arm 111 is moved to the upper position before the worker O puts the next package W into the pusher device 102. This simplifies the work of the worker O to return the package W to the removal position 113b.

[0046] 2. Second embodiment In the first embodiment, the drawer table is fixed, but it may have another configuration. Such an embodiment will be described as a second embodiment with reference to Figures 18 and 19. Figures 18 and 19 are schematic side views of a work station apparatus according to the second embodiment. The basic configuration and basic operation of the second embodiment are the same as those of the first embodiment.

[0047] The work station apparatus 101A has a pull-out table 103A. The drawer table 103A has a flat first portion 103A1 on the transport vehicle 3 side, and a rotatable second portion 103A2 on the opposite side of the first portion 103A1 from the transport vehicle 3. The second portion 103A2 is rotatable between a flat position (FIG. 18) and an upright position (storage position, FIG. 19) rotated upward. The second portion 103A2 is connected to the first portion 103A1 via a rotating portion 103A3. Although not shown, the second portion 103A2 is held in both of the above positions by a stopper.

[0048] In this embodiment, by moving the second portion 103A2 of the drawer table 103A to the upright position, the worker O can approach the pusher device 102, thereby improving workability. Furthermore, for example, when the worker O pulls out a package from the support base 113 (not shown) to the drawer table 103A, the worker O can stop the package W by hitting it against the second portion 103A2 by moving the second portion 103A2 of the drawer table 103A to the upright position as shown in Fig. 19. Furthermore, even in this state, the worker O can take out the package W from the drawer table 103A. Also, for example, when worker O places luggage W located outside on drawer table 103A, the luggage W can be easily placed on drawer table 103A by moving second portion 103A2 of drawer table 103A to a flat posture position as shown in FIG. 18.

[0049] 3. Common features of the embodiments The above first and second embodiments have the following configurations and functions in common. The work station apparatus (for example, the work station apparatus 101, 101A) is disposed near an automated warehouse having racks and a storage / retrieval apparatus. The work station apparatus includes a pusher apparatus and a pull-out table. A pusher device (for example, the pusher device 102) is disposed adjacent to a rack and moves a load by pushing it from the rack side to a work area side located away from the rack. The pull-out table (eg, pull-out table 103) is disposed on the working area side of the pusher device, and has an upper surface (eg, upper surface 103a) on which a worker can pull out and place the baggage pushed out by the pusher device. In this device, a pusher device and a drawer table are provided between the worker in the work area and the loading / unloading device of the automated warehouse. In other words, by providing the pusher device and the drawer table, the worker can be kept away from the loading / unloading device of the automated warehouse.

[0050] 4. Other embodiments Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the invention. In particular, the multiple embodiments and modifications described in this specification can be arbitrarily combined as necessary. (1) Modified example of pusher device The number of pairs of pusher device and pull-out table may be one, or three or more. The pusher device may have other configurations, and may be composed of a rotating belt, a protrusion provided on the outside of the rotating belt, and a claw that moves back and forth.
