Description

  The present invention relates to a store system that performs work first-in first-out using an automated guided vehicle.

Basic store methods include a fixed location method, a free location method, and a double transaction method.
The fixed location method is a method for determining a storage place for each type of work. However, the fixed location method lacks flexibility for process changes and layout changes, and is not space efficient. This is because the storage location is determined for the convenience of the take-out side. The free location method is a method in which various works are stored in an empty place, and the double transaction method is a method in which a fixed location method and a free location method are combined. However, the free location method and the double transaction method basically require inventory management, and it is necessary to always match the management data with the work itself (inventory is necessary). In the double transaction method, it is possible to install a shooter in the storage unit and omit data management. However, when handling heavy objects, it is necessary to increase the weight of the equipment and install it on the floor. Lack of flexibility for layout changes.

  Further, in Patent Document 1, an automatic guided vehicle that can automatically travel along a non-orbital travel line is provided, and a plurality of article storage spaces are provided in an arbitrary part along the travel line in the travel direction and the vertical direction. A warehouse system using an automatic guided vehicle in which a shelf is provided and a transfer robot is provided on the automatic guided vehicle to deliver an article to and from the article storage space of the shelf is disclosed.

Next, the operation of the store system 1 according to the embodiment of the present invention will be described.
First, an operation in which the automatic guided vehicle 2 travels along the carry-in route 15 (black coating in FIG. 1) and stores the transported carriage 3a that accommodates the workpiece W in the store area 11 will be described.
First, when the automated guided vehicle 2 is towing an empty transported cart 3b, the automated guided vehicle 2 receives and stores the information “active cart is being pulled” from the management system via the AGV control device 40. Yes. Subsequently, the automatic guided vehicle 2 pulls the empty transported carriage 3b and travels on the carry-in route 15 toward the store entrance 10 (in one direction). Then, the automatic guided vehicle 2 enters the store entrance 10 when the stored information “Towing empty cart” coincides with the detection ID tag 35 during towing the empty cart pasted near the store entrance 10. To do.

Next, at the store entrance 10, one or a plurality of workpieces W are received into the empty transported carriage 3 b. Subsequently, the automatic guided vehicle 2 receives the information of “work ID” and “under towing” as information of the received work W from the management system via the AGV control device 40 and updates the storage. Subsequently, the automatic guided vehicle 2 pulls the transported carriage 3a that accommodates the workpiece W, exits the store entrance 10, and travels along the carry-in route 15 in one direction (the direction of the arrow).
Next, the automated guided vehicle 2 has the stored “work ID” and each of the work ID tags 41 to 50 pasted at the entrances of the first to tenth store lanes 21 to 30 of the store area 11. The vehicle travels in one direction along the carry-in route 15 while checking each other.

  When the “work ID” stored in the automatic guided vehicle 2 matches, for example, the work ID tag 42 affixed to the entrance of the second store lane 22, the automatic guided vehicle 2 moves from the carry-in route 15 to the second store. Enter the lane 22. The automatic guided vehicle 2 is positioned in the second store lane 22 until the front carriage detection device is activated, that is, the rearmost (most entrance side) where the automatic guided vehicle 2 is stored in the second store lane 22. The vehicle travels until the distance to the transported carriage 3a reaches a predetermined value or less. Then, when the forward cart detection device of the automatic guided vehicle 2 is activated, the connection between the automatic guided vehicle 2 and the transported cart 3a is released by a signal from the AGV control device 40. At this time, the transported carriage 3a that has been carried into the rear of the transported carriage 3a that is stored in the second store lane 22 and located at the rearmost (most entrance side) is automatically moved by the carriage coupling mechanism 5 described above. It will be in the state connected with.

If no carriage 3a is stored in the ninth store lane 29 as in the ninth store lane 29, the automatic guided vehicle 2 is placed in the front row of the ninth store lane 29 (mostly It travels to the exit side), and the connection between the automatic guided vehicle 2 and the transported carriage 3a is released by a signal from the AGV control device 40.
Next, after the connection with the transported carriage 3 a is released, the automatic guided vehicle 2 runs backward in the second store lane 22 and exits from the second store lane 22. Subsequently, the automatic guided vehicle 2 receives information of “non-traction” from the management system via the AGV control device 40 and updates the storage.
Next, the automatic guided vehicle 2 that has returned to the carry-in route 15 travels in one direction in a state in which the guided carts 3 a and 3 b are not pulled, and is finally stored in the automatic guided vehicle 2. When the “non-traction” information matches the non-traction detection ID tag 36 affixed to the entrance of the empty cart standby area 12, the vehicle enters the empty cart standby area 12 from the carry-in route 15.

Next, the automatic guided vehicle 2 is connected to an empty transported carriage 3b located on the most exit side in the empty carriage standby area 12 by a signal from the AGV control device 40. Subsequently, when the automatic guided vehicle 2 moves forward to leave the empty cart standby area 12, the pulled transported cart 3 b and the empty transported cart 3 b located behind the guided cart 3 are The connection is released. Subsequently, the automatic guided vehicle 2 pulls the empty transported carriage 3 b to leave the empty carriage standby area 12 and returns to the carry-in route 15.
Next, the automated guided vehicle 2 receives the information “pulling the empty carriage” from the management system via the AGV control device 40, updates the memory, travels in the carry-in route 15 in one direction, and is described above. The operation is repeated.

Next, the automatic guided vehicle 2 travels along the unloading route 17 (indicated by white in FIG. 1), transports the transported carriage 3 a containing the workpiece W from the store area 11 to the store outlet 16, and unloads the workpiece W. explain.
First, when the automatic guided vehicle 2 pulls the transported carriage 3a in which the workpiece W is accommodated and travels along the unloading route 17 in one direction (the direction of the arrow), the automatic guided vehicle 2 is Information of “work ID”, “during towing”, and “store exit” as information of the work W accommodated in the transported carriage 3a is stored. When this automated guided vehicle 2 passes the store exit detection ID 37 affixed in the vicinity of the store exit 16, the stored "store exit" information matches the store exit detection ID tag 37. The transport vehicle 2 enters the store outlet 16 and the work W in the transported carriage 3a is unloaded.

At this time, the automatic guided vehicle 2 receives the information “pulling the empty cart” from the management system via the AGV control device 40 and updates the memory only when all the workpieces W in the cart 3a are carried out. . Other than that, for example, when all the workpieces W are not carried out for some reason (not empty), the currently stored information, that is, the information of “being towed” and “work ID” is held.
Next, the automatic guided vehicle 2 exits from the store exit 16 and travels along the carry-out route 17 in one direction (the direction of the arrow).

  Next, when the automatic guided vehicle 2 traveling in one direction on the unloading route 17 stores information indicating that the empty cart is being pulled, the stored information indicating that the empty cart is being pulled is stored. The automatic guided vehicle 2 enters the empty cart standby area 12 from the carry-out route 17 in line with the detection ID tag 35 during towing empty cart pasted at the entrance of the empty cart standby area 12. The automatic guided vehicle 2 travels in the empty cart standby area 12 until the front cart detection device is activated. When the forward cart detection device of the automatic guided vehicle 2 is activated, the connection between the automatic guided vehicle 2 and the empty transported cart 3b is released by a signal from the AGV control device 40. At this time, the empty transported carriage 3b that has been carried in is automatically connected by the truck connecting mechanism 5 behind the empty transported truck 3b that is stored in the empty cart standby area 12 and is located closest to the entrance. It will be in a state to be.

  Next, the automatic guided vehicle 2 runs backward in the empty cart standby area 12 and exits from the empty cart standby area 12. Subsequently, the automated guided vehicle 2 that has left the empty cart standby area 12 receives information on “work ID” and “non-traction” that needs to be carried out from the management system via the AGV control device 40 and updates the storage. .

  On the other hand, when the automatic guided vehicle 2 that has pulled the transported carriage 3a with the workpiece W remaining therein exits the store exit 16 and travels in the unloading route 17 in one direction, Since the memory is in a held state, the automated guided vehicle 2 uses the stored “work ID” and the work ID pasted at the exits of the first to tenth store lanes 21 to 30 in the store area 11. The vehicle travels in one direction along the carry-out route 17 while collating with each of the tags 51-60. When the “work ID” stored in the automatic guided vehicle 2 matches, for example, the work ID tag 56 pasted at the exit of the sixth store lane 26, the automatic guided vehicle 2 moves from the carry-out route 17 to the sixth store. The vehicle enters the lane 26, and at the front row (most exit side) of the sixth store lane 26, the connection between the automatic guided vehicle 2 and the guided vehicle 3a is released by a signal from the AGV control device 40. In the store system 1, after the unmanned transport vehicle 2 once carries out the transport operation of the transported carriage 3 a located in the front row in each store lane 21 to 30, the transported carriage 3 a described above is returned. As long as the operation is not performed, the front row of each store lane 21 to 30 is vacant due to the action of the carriage coupling mechanism 5. Subsequently, the automatic guided vehicle 2 that has left the sixth store lane 26 receives information on “work ID” and “non-traction” that needs to be carried out from the management system via the AGV control device 40 and updates the storage. To do.

Next, the automatic guided vehicle 2 is in a non-traction state, and the stored “work ID” and the work ID tag 51 pasted at the exits of the first to tenth store lanes 21 to 30 of the store area 11 are stored. The vehicle travels in one direction on the carry-out route 17 while collating with each of ˜60.
When the “work ID” stored in the automatic guided vehicle 2 matches, for example, the work ID tag 54 pasted at the exit of the fourth store lane 24, the automatic guided vehicle 2 moves from the carry-out route 17 to the fourth store. Enter the front row in the lane 24. Subsequently, the automatic guided vehicle 2 is connected to the transported carriage 3 a stored in the front row (most exit side) of the fourth store lane 24 by a signal from the AGV control device 40. Subsequently, when the automatic guided vehicle 2 moves forward to leave the fourth store lane 24, the pulled carriage 2 a and the rear carriage 3 a are disconnected by the carriage coupling mechanism 5.
When the transported carriage 3a is not stored in the frontmost row (most exit side) as in the first store lane 21, the automatic guided vehicle 2 further enters the first store lane 21. Connected to the transported carriage 3a stored in the next row, exits the first store lane 21, returns to the carry-out route 17 and travels in one direction. Also at this time, the pulled carriage 3a and the carriage 3a behind it are disconnected by the carriage coupling mechanism 5 when passing through the front row (most exit side) of the first store lane 21. The

  Next, in addition to the currently stored “work ID”, the automatic guided vehicle 2 receives and stores information on “towing” and “store exit” from the management system via the AGV control device 40. Then, the unmanned transport vehicle 2 travels in one direction along the unloading route 17, and the “store exit” information stored in the unmanned transport vehicle 2 is stored at the store exit detection ID tag. If it coincides with 37, it enters the store exit 16 and the work W in the transported carriage 3a is carried out. Thereafter, the above-described operation is repeated.

As described above, in the store system 1 according to the embodiment of the present invention, the transport route of the automatic guided vehicle 2 is such that the transported carriage 3a that accommodates the work W is stored in each store lane 21 to 30 of the store area 11.
