Description

Technical Field

[0001] The present application relates to the field of parking machinery, and in particular to a transportation control method for a three-dimensional parking garage with a ring distribution line. Background Art

[0002] A mechanical three-dimensional parking garage is a mechanical device that integrates vehicle handling, parking, and storage. In the current design of three-dimensional parking garages, a number of pallets for parking vehicles are set in the shelves of the parking garage, and a number of lanes are set under the shelves. Stackers for storing or taking out pallets are set in the lanes. These lanes correspond to the entrances and exits of the parking garage one by one. However, during use, the number of vehicles entering the entrances and exits of the parking garage will be affected by factors such as the road section and time, resulting in different traffic volumes at each entrance and exit. The number of pallets that the stackers in the lanes corresponding to each entrance and exit need to store and take is not the same. In other words, in the same time period, the stackers in some lanes are running at full load, while the stackers in some lanes are running at low load. The utilization efficiency of each stacker is low, which affects the efficiency of storing and retrieving vehicles in the three-dimensional parking garage. Summary of the invention

[0003] In view of this, the present application provides a conveying control method for a three-dimensional parking garage with a ring distribution line, which is used to solve the problem of low vehicle storage and retrieval efficiency caused by different numbers of pallets stored and retrieved by each stacker in the same time period in each lane of the existing warehouse-type mechanical three-dimensional parking garage.

[0004] In order to solve the above technical problems, this application adopts the following technical solutions:

[0005] According to an embodiment of the present application, a conveying control method for a three-dimensional parking garage with a ring distribution line is applied to a three-dimensional parking garage, and the three-dimensional parking garage includes:

[0006] Shelves, the shelves include multiple layers, and multiple pallets are arranged in the shelves;

[0007] A stacker is provided throughout each layer of the shelf, and the stacker includes at least one;

[0008] The circular distribution line comprises a circular track and a plurality of circular conveying vehicles arranged on the circular track, and roller conveyors are arranged on the circular conveying vehicles;

[0009] The roller conveyor line includes a first roller conveyor unit, a second roller conveyor unit, a third roller conveyor unit, and a pallet extracting mechanism. The second roller conveyor unit and the third roller conveyor unit are symmetrically arranged on both sides of the stacker entrance and exit and are connected to the stacker entrance and exit. The second roller conveyor unit is provided with a pallet unstacking machine.

[0010] Control methods include:

[0011] S100, the stacker extracts a plurality of pallets from the shelf and conveys the plurality of pallets to the second roller conveyor unit;

[0012] S200, the second roller conveyor group splits the multiple pallets into single pallets through the pallet destacker and conveys them to the ring conveyor vehicle of the ring distribution line;

[0013] S300, the circular conveyor transports the pallet to the first roller conveyor unit;

[0014] S400, after the pallet supporting vehicle, the first roller conveyor unit conveys the pallet to the circular conveyor vehicle of the circular distribution line;

[0015] S500, the circular conveyor transports the pallet to the third roller conveyor unit;

[0016] S600: The third roller conveyor unit transports the pallet carrying the vehicle to the entrance and exit of the stacker, and the stacker stores the pallet carrying the vehicle into the shelf.

[0017] In a preferred embodiment of the present application, the first roller conveyor group includes several, that is, the three-dimensional parking garage can include several vehicle entrances and exits. In practical applications, taking the parking process as an example, any stacker can extract a pallet from the shelf, and split multiple pallets into single pallets through the second roller conveyor group and then transport them to the ring distribution line. The controller of the ring distribution line can detect whether there is a pallet at the vehicle entrance and exit corresponding to each vehicle access port. If there is no pallet, the ring conveyor vehicle will transport the pallet to the first roller conveyor group corresponding to the vehicle entrance and exit to wait for the driver to park the vehicle. After the pallet supports the vehicle, the first roller conveyor group transports the pallet to the ring conveyor vehicle of the ring distribution line. At this time, the controller of the ring distribution line can detect the stacker that is currently idle or about to complete the vehicle storage and retrieval task, and make the ring conveyor vehicle transport the pallet to the third roller conveyor group of the corresponding stacker. The third roller conveyor group of the corresponding stacker can transport the pallet carrying the vehicle to the stacker entrance and exit, and the stacker will store the pallet carrying the vehicle in the shelf.

[0018] In one embodiment of the present application, the second roller conveyor group includes a first roller conveyor and a second roller conveyor, and conveying a plurality of pallets to the second roller conveyor group includes:

[0019] S101, the stacker extracts a plurality of pallets from the shelf and places them on the first roller conveyor;

[0020] S102: The first roller conveyor transports the plurality of stacked pallets to the second roller conveyor, and the second roller conveyor is provided with a pallet destacking machine.

[0021] In one embodiment of the present application, the second roller conveyor unit splits a plurality of pallets into single pallets through a pallet destacker and conveys the pallets to a circular conveyor vehicle of a circular distribution line, comprising:

[0022] S201, the destacker destacker destackers multiple stacked pallets and places a single pallet on the second roller conveyor;

[0023] S202: The second roller conveyor transports the pallet to the roller conveyor disposed on the circular conveyor vehicle.

[0024] Specifically, when parking demand is detected at a vehicle entrance or exit, the circular conveyor vehicle can travel to the second roller conveyor group where pallets are stored on the second roller conveyor. At this time, the destacker can separate multiple stacked pallets and place a single pallet on the second roller conveyor. The second roller conveyor then transports the pallet to the roller conveyor set on the circular conveyor vehicle.

[0025] In one embodiment of the present application, the circular conveyor transports the pallet to the first roller conveyor unit, including:

[0026] S301, the circular conveyor vehicle transports the pallet to the first roller conveyor unit along the circular track.

[0027] That is to say, the endless conveyor vehicle can transport the pallet to the first roller conveyor unit corresponding to the vehicle entrance and exit where parking is required.

[0028] In one embodiment of the present application, the first roller conveyor group includes a third roller conveyor, a fourth roller conveyor, and a fifth roller conveyor;

[0029] After the pallet carrier vehicle, the first roller conveyor unit transports the pallet to the circular conveyor vehicle of the circular distribution line, including:

[0030] S401, the third roller conveyor and the fourth roller conveyor sequentially transport the pallet on the circular conveyor vehicle to the fifth roller conveyor, and wait for the driver to drive the vehicle onto the pallet;

[0031] S402: After the pallet supports the vehicle, the fifth roller conveyor, the third roller conveyor and the fourth roller conveyor are reversed to transport the pallet to the circular conveyor vehicle.

[0032] S403, when the fourth roller conveyor reverses to convey the pallet carrying the vehicle, it rotates horizontally by 180 degrees.

[0033] Specifically, since the fourth roller conveyor rotates 180° horizontally when conveying the pallet carrying the vehicle, the driver does not need to back up and turn the vehicle when parking. In other words, the vehicle can enter the warehouse directly with its front facing away from the vehicle entrance and exit, and the pallet carrying the vehicle is rotated 180° horizontally by the fourth roller conveyor. At this time, when the driver takes the vehicle, the front of the vehicle faces the vehicle entrance and exit, and the vehicle can leave the warehouse directly.

[0034] In one embodiment of the present application, the circular conveyor transports the pallet to the third roller conveyor assembly.

[0035] S501, the circular conveyor vehicle moves counterclockwise along the circular track to the third roller conveyor unit.

[0036] Specifically, when an idle stacker is detected or the stacker is about to complete the task of storing and retrieving a vehicle, the circular conveyor vehicle can transport the pallet carrying the vehicle to the third roller conveyor group corresponding to the stacker.

[0037] In one embodiment of the present application, the third roller conveyor group includes a sixth roller conveyor and a seventh roller conveyor;

[0038] The third roller conveyor unit transports the pallet with the vehicle to the stacker entrance and exit, and the stacker stores the pallet with the vehicle in the shelf, including

[0039] S601, the sixth roller conveyor transports the pallet carrying the vehicle to the seventh roller conveyor;

[0040] S602, the stacker takes the pallet carrying the vehicle from the seventh roller conveyor and stores the pallet carrying the vehicle into the shelf, thus completing the vehicle storage process.

[0041] In one embodiment of the present application, the vehicle picking process is performed in reverse order to the vehicle storage process, and the fourth roller conveyor no longer rotates horizontally by 180°.

[0042] The following is a detailed introduction to the vehicle retrieval process. When the driver picks up the vehicle at the vehicle access port, the idle stacker closest to the vehicle can take out the pallet carrying the vehicle and transport it to the seventh roller conveyor of the corresponding third roller conveyor group, and then the seventh roller conveyor will transport it to the sixth roller conveyor, and then the sixth roller conveyor will transport the pallet carrying the vehicle to the roller conveyor of the circular conveyor. The circular conveyor transports the pallet carrying the vehicle to the third roller conveyor of the first roller conveyor group at the vehicle entrance and exit where the driver is waiting, and then the third roller conveyor and the fourth roller conveyor transport the pallet carrying the vehicle to the fifth roller conveyor. At this time, the fourth roller conveyor does not need to rotate. When the pallet reaches the fifth roller conveyor, the driver can take the vehicle away.

[0043] In a preferred embodiment of the present application, the annular distribution line can be of any shape, such as an "O" shape, an "L" shape, etc., and can be matched according to the conditions of the plot, and there is no limitation here.

[0044] The above technical solution of the present application has at least one of the following beneficial effects:

[0045] The conveying control method of the three-dimensional parking garage with a ring distribution line in the embodiment of the present application uses a ring conveyor line to transport pallets, so that each vehicle entrance and exit and the stacker of each lane no longer correspond one to one. The pallets can be reasonably distributed according to the vehicle entrance and exit traffic and the processing efficiency of the stacker. The pallet processing load of each stacker is balanced, which increases the freedom of position selection and effectively improves the efficiency of storing and retrieving vehicles in the three-dimensional parking garage. At the same time, the conveying control method of the three-dimensional parking garage in the present application realizes the automation of transportation and storage of vehicles and pallets, further improving the efficiency of storing and retrieving vehicles.

DETAILED DESCRIPTION

[0054] In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the embodiment of the present application will be clearly and completely described below in conjunction with the drawings of the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0055] Unless otherwise defined, the technical terms or scientific terms used in this application should be understood by people with ordinary skills in the field to which this application belongs. The "first", "second" and similar words used in this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, similar words such as "one" or "one" do not indicate quantity restrictions, but indicate the existence of at least one. Similar words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0056] Since the number of vehicles at each entrance and exit of a three-dimensional parking garage is affected by factors such as road sections and time, the traffic volume at each entrance and exit is different, and the number of pallets that the stackers in the lanes corresponding to each entrance and exit need to store and retrieve is different, resulting in an unbalanced load on each stacker and low efficiency in storing and retrieving vehicles. At the same time, the existing three-dimensional parking garage has a low degree of automation and requires manual monitoring of the parking conditions at each vehicle entrance and exit. In order to solve the above problems, the present application provides a transportation control method for a three-dimensional parking garage with a ring distribution line.

[0057] The following first describes in detail the transportation control method of a three-dimensional parking garage with a ring distribution line according to an embodiment of the present application with reference to the accompanying drawings.

[0058] Figure 1 This is a flow chart of a method for controlling the transport of a three-dimensional parking garage with a ring distribution line according to an embodiment of the present application. The control method is applied to a three-dimensional parking garage, combined with Figure 1 and Figure 2 and Figure 3 As shown, the three-dimensional parking garage includes: a shelf 100, a stacker 120, a ring distribution line 200 and a roller conveyor line 300. Among them, the shelf 100 includes multiple layers, and multiple pallets 110 are arranged in the shelf 100; the stacker 120 runs through each layer of the shelf 100, and the stacker 120 includes at least one part; the circular distribution line 200 includes a circular track 210 and multiple circular conveyor vehicles 220 arranged on the circular track 210, and the circular conveyor vehicles 220 are provided with roller conveyors 230. The outer side of the circular distribution line 200 is also provided with a maintenance platform 240 for repairing the circular conveyor vehicles 220; the roller conveyor line 300 includes a first roller conveyor group 320, a second roller conveyor group 310, and a third roller conveyor group 350. The first roller conveyor group 320 is arranged on the outer side of the circular distribution line 200, the second roller conveyor group 310 and the third roller conveyor group 350 are symmetrically arranged on both sides of the entrance and exit of the stacker 120 and are connected to the entrance and exit of the stacker 120, and the second roller conveyor group 310 is provided with a destacking machine 313.

[0059] Control methods include:

[0060] S100, the stacker extracts a plurality of pallets from the shelf and conveys the plurality of pallets to the second roller conveyor unit;

[0061] S200, the second roller conveyor group splits the multiple pallets into single pallets through the pallet destacker and conveys them to the ring conveyor vehicle of the ring distribution line;

[0062] S300, the circular conveyor transports the pallet to the first roller conveyor unit;

[0063] S400, after the pallet supporting vehicle, the first roller conveyor unit conveys the pallet to the circular conveyor vehicle of the circular distribution line;

[0064] S500, the circular conveyor transports the pallet to the third roller conveyor unit;

[0065] S600: The third roller conveyor unit transports the pallet carrying the vehicle to the entrance and exit of the stacker, and the stacker stores the pallet carrying the vehicle into the shelf.

[0066] In a preferred embodiment of the present application, the first roller conveyor group 320 includes several first roller conveyor groups 320, a vehicle entrance and exit is provided at the first roller conveyor group 320, and a parking reflector 340 is provided at the vehicle entrance and exit, that is, the three-dimensional parking garage may include several vehicle entrances and exits. In practical applications, taking the parking process as an example, any stacker 120 can extract a pallet 110 from the shelf 100, and separate the multiple pallets 110 into a single pallet 110 through the second roller conveyor group 310 and then transport them to the annular distribution line 200. The controller of the annular distribution line 200 can detect whether there is a pallet 110 at the vehicle entrance and exit corresponding to each vehicle access port. If there is no pallet 110, the annular conveyor 220 will transport the pallet 110 to the first roller conveyor group 320 corresponding to the vehicle entrance and exit to wait for the driver to park the vehicle. After the pallet 110 supports the vehicle, the first roller conveyor group 320 conveys the pallet 110 to the circular conveyor vehicle 220 of the circular distribution line 200. At this time, the controller of the circular distribution line 200 can detect the stacker 120 that is currently idle or is about to complete the vehicle storage and retrieval task, and enable the circular conveyor vehicle 220 to transport the pallet 110 to the third roller conveyor group 350 corresponding to the stacker 120. The third roller conveyor group 350 corresponding to the stacker 120 can transport the pallet 110 carrying the vehicle to the entrance and exit of the stacker 120, and the stacker 120 will store the pallet 110 carrying the vehicle in the shelf 100. That is to say, when transporting the pallet 110 through the circular distribution line 200, the vehicle entrance and exit do not need to correspond one to one with the entrance and exit of the stacker 120. When a parking demand is detected at the vehicle entrance and exit, the circular conveyor vehicle 220 can extract the pallet 110 from the second roller conveyor group 310 under any idle stacker 120. At the same time, when there is a vehicle on the pallet 110, the stacker 120 that is idle or about to complete the storage and retrieval work can be detected, and the pallet 110 carrying the vehicle can be transported to the corresponding stacker 120, so that the stacker 120 and the pallet 110 can be flexibly called, thereby improving the utilization efficiency of the stacker 120 and improving the efficiency of vehicle storage and retrieval.

[0067] In one embodiment of the present application, the second roller conveyor group includes a first roller conveyor and a second roller conveyor; conveying a plurality of pallets to the second roller conveyor group includes:

[0068] S101, the stacker extracts a plurality of pallets from the shelf and places them on the first roller conveyor;

[0069] S102: The first roller conveyor transports the plurality of stacked pallets to the second roller conveyor, and the second roller conveyor is provided with a pallet destacking machine.

[0070] That is to say, the first roller conveyor 311 and the second roller conveyor 312 are used to specifically transport empty pallets 110. The second roller conveyor group 310 for transporting empty pallets 110 and the third roller conveyor group 350 for transporting pallets 110 loaded with vehicles are respectively provided, which can effectively improve the efficiency of the stacker 120.

[0071] In one embodiment of the present application, the second roller conveyor unit splits a plurality of pallets into single pallets through a pallet destacker and conveys the pallets to a circular conveyor vehicle of a circular distribution line, comprising:

[0072] S201, the destacker destacker destackers multiple stacked pallets and places a single pallet on the second roller conveyor;

[0073] S202: The second roller conveyor transports the pallet to the roller conveyor disposed on the circular conveyor vehicle.

[0074] Specifically, when a parking demand is detected at a vehicle entrance or exit, the circular conveyor 220 can travel to the second roller conveyor group 310 where the pallet 110 is stored on the second roller conveyor 312, and the destacker 313 can destacker the multiple stacked pallets 110 and place a single pallet 110 on the second roller conveyor 312, and then the second roller conveyor 312 transports the pallet 110 to the roller conveyor 230 provided on the circular conveyor 220. By transporting the empty pallet 110 by the circular conveyor 220, the pallet 110 can be quickly transported to the vehicle entrance or exit, further improving the efficiency of storing and retrieving vehicles.

[0075] In one embodiment of the present application, the circular conveyor transports the pallet to the first roller conveyor unit, including:

[0076] S301, the circular conveyor vehicle transports the pallet counterclockwise along the circular track to the first roller conveyor unit.

[0077] That is, the endless conveyor vehicle 220 can transport the pallet 110 counterclockwise to the first roller conveyor unit 320 corresponding to the vehicle entrance or exit where parking is required.

[0078] In one embodiment of the present application, the first roller conveyor group includes a third roller conveyor, a fourth roller conveyor, and a fifth roller conveyor;

[0079] After the pallet carrier vehicle, the first roller conveyor unit transports the pallet to the circular conveyor vehicle of the circular distribution line, including:

[0080] S401, the third roller conveyor and the fourth roller conveyor sequentially transport the pallet on the circular conveyor vehicle to the fifth roller conveyor, and wait for the driver to drive the vehicle onto the pallet;

[0081] S402: After the pallet supports the vehicle, the third roller conveyor, the fourth roller conveyor and the fifth roller conveyor are reversed to transport the pallet to the circular conveyor vehicle.

[0082] S403, the fourth roller conveyor rotates horizontally 180° when conveying the pallet carrying the vehicle;

[0083] Specifically, since the fourth roller conveyor 322 rotates horizontally 180° when conveying the pallet 110 carrying the vehicle, the driver does not need to park the vehicle in reverse and turn the vehicle around when parking. In other words, the front of the vehicle can enter the warehouse directly, with the front of the vehicle facing away from the vehicle entrance and exit, and the pallet 110 carrying the vehicle is rotated horizontally 180° by the fourth roller conveyor 322. At this time, when the driver retrieves the vehicle, the front of the vehicle faces the vehicle entrance and exit, and the front of the vehicle can be directly taken out of the warehouse. This effectively improves the efficiency of storing and retrieving vehicles and the user experience.

[0084] In one embodiment of the present application, the circular conveyor transports the pallet to the third roller conveyor unit S501, and the circular conveyor moves counterclockwise along the circular track to the third roller conveyor unit.

[0085] Specifically, when an idle stacker 120 is detected or the stacker 120 is about to complete the vehicle storage and retrieval task, the circular conveyor 220 can transport the pallet 110 carrying the vehicle to the third roller conveyor group 350 corresponding to the stacker 120. By transporting the pallet 110 carrying the vehicle to the idle stacker 120, the utilization efficiency of the stacker 120 can be effectively improved.

[0086] In one embodiment of the present application, the third roller conveyor group includes a sixth roller conveyor and a seventh roller conveyor;

[0087] The third roller conveyor unit transports the pallet with the vehicle to the stacker entrance and exit, and the stacker stores the pallet with the vehicle in the shelf, including

[0088] S601, the sixth roller conveyor transports the pallet carrying the vehicle to the seventh roller conveyor;

[0089] S602, the stacker takes the pallet carrying the vehicle from the seventh roller conveyor and stores the pallet carrying the vehicle into the shelf, thus completing the vehicle storage process.

[0090] In one embodiment of the present application, the vehicle picking process is performed in reverse order to the vehicle storage process, and the fourth roller conveyor 322 no longer rotates horizontally by 180°.

[0091] The following is a detailed description of the car pick-up process: Figure 4As shown, when the driver picks up a vehicle at the vehicle access port, the idle stacker 120 closest to the vehicle can take out the pallet 110 carrying the vehicle and convey it to the seventh roller conveyor 352 of the corresponding third roller conveyor group 350, and then conveyed by the seventh roller conveyor 352 to the sixth roller conveyor 351, and then the sixth roller conveyor 351 transports the pallet 110 carrying the vehicle to the roller conveyor 230 of the circular conveyor vehicle 220. The circular conveyor 220 transports the pallet 110 carrying the vehicle to the vehicle entrance and exit where the driver is waiting, and transports the pallet 110 carrying the vehicle to the third roller conveyor 321 of the corresponding first roller conveyor group 320, and then the third roller conveyor 321 and the fourth roller conveyor 322 transport the pallet 110 carrying the vehicle to the fifth roller conveyor 323. At this time, the fourth roller conveyor 322 does not need to rotate. When the pallet 110 arrives at the fifth roller conveyor 323, the driver can take the vehicle away. Then, the empty pallet 110 can be stored in the shelf 100 again. Specifically, Figure 5 As shown, the empty pallets 110 can be transported to the circular conveyor 220 by reversely using the third roller conveyor 321, the fourth roller conveyor 322 and the fifth roller conveyor 323, and then the circular conveyor 220 drives the pallets 110 to move on the circular track 210 and arrive at the second roller conveyor 312, where the pallets 110 are stacked by the destacker 313. After a certain number of pallets 110 are stacked, they arrive at the first roller conveyor 311 and wait for the stacker 120 to be idle before moving the pallets 110 to the shelf 100.

[0092] like Figure 6 and Figure 7 As shown, in the preferred embodiment of the present application, the annular distribution line 200 can be of any shape, such as an "O" shape, i.e., an O-shaped annular distribution line 250, or an "L" shape, i.e., an L-shaped annular distribution line 260, which can be matched according to the conditions of the plot and is not limited here.

[0093] The conveying control method of the three-dimensional parking garage with the annular distribution line 200 of the embodiment of the present application uses the annular conveyor line to transport the pallets 110, so that each vehicle entrance and exit and the stacker 120 of each lane no longer correspond one to one. The pallets 110 can be reasonably distributed according to the vehicle flow at the vehicle entrance and exit and the processing efficiency of the stacker 120, and the pallet 110 processing load of each stacker 120 is balanced, which effectively improves the utilization efficiency of the stacker 120, improves the freedom of position selection, and effectively improves the efficiency of storing and retrieving vehicles in the three-dimensional parking garage. At the same time, the conveying control method of the three-dimensional parking garage of the present application realizes the automation of the transportation and storage of vehicles and pallets 110, further improving the efficiency of storing and retrieving vehicles.

[0094] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
