Description

Technical Field

[0001] The invention relates to an automatic dispatching method for a relay-type vertical sorting machine, belonging to the technical field of control methods. Background Art

[0002] Vertical sorters are widely used in automated logistics systems. Traditional vertical sorters are mostly single-unit reciprocating or circular sorters. Single-unit reciprocating sorters have limited efficiency and can only transport a fixed amount of goods at a time. While they are ideal for short-distance transport, their efficiency is limited in high-rise, long-distance transport. Circular sorters offer high efficiency but are also suitable for short distances. They are not suitable for high-rise, long-distance transport due to the combined effects of site and height. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides an automatic scheduling method for a relay-type vertical sorting machine. The automatic scheduling method for a relay-type vertical sorting machine uses multiple vertical sorting machines in the same shaft for relay transmission, effectively improving the transmission efficiency, thereby improving the transmission efficiency and achieving more precise equipment control.

[0004] The present invention is achieved through the following technical solutions.

[0005] The present invention provides an automatic scheduling method for a relay-type vertical sorting machine, wherein the cargo signal is a signal emitted by an electronic component when cargo is present at a pickup position of an elevator car, and the task number is an identification number assigned when the elevator car is in an idle state, and the method comprises the following steps:

[0006] S1. Check: Get the delivery task information and cyclically check whether there is a loading signal at each pickup location;

[0007] S2. Find the task number: For the pickup location with the loading signal, traverse and calculate to find the task number closest to it, and open the synchronization lock for the task number closest to it;

[0008] S3. Issue pickup instruction: Send a pickup instruction to the elevator car corresponding to the task number and simultaneously start the pickup control process, unlock the synchronization lock of the corresponding task number and cancel it; the pickup instruction includes the pickup location and target location;

[0009] S4, automatic transport: The elevator car enters the pickup control process according to the pickup instruction, first moves to the pickup position and stops, then loads the goods, and then the elevator car moves to a relatively close position and stops; the relatively close position is the position closer to the target position and the maximum range position;

[0010] S5. Cargo release reset: If the relative close position is the target position, the cargo will be unloaded; if the relative close position is the maximum range position, the current elevator car will send a cargo signal to wait for other elevator cars to arrive at the unloading position, then receive the cargo, and then move to the initial position and set the task number.

[0011] The unloading is to open the drum in the unloading direction until a period of time after the loading signal is generated.

[0012] The receiving of goods is to open the drum in the down direction for a period of time.

[0013] The loading is performed by opening the roller in the loading direction to pick up the goods until the loading signal disappears and the goods are empty for a period of time.

[0014] The maximum range position is the furthest position to which the elevator car can travel from an initial position.

[0015] Before opening the roller, first check whether the landing door is open, and if it is not open, alarm will be issued.

[0016] After the period of time, check whether the layer is closed. If it is closed, proceed to the next step. If it is not closed, an alarm is issued.

[0017] In step S1, when the cargo signal is cyclically checked, the task number is queried at the same time.

[0018] In step S5, after receiving the goods, the other elevator cars send a pickup completion instruction to the current elevator car.

[0019] The beneficial effects of the present invention are: using multiple vertical sorting machines for relay transmission in the same shaft, effectively improving the transmission efficiency, thereby improving the transmission efficiency, achieving more accurate equipment control, and automatically scheduling the elevator, avoiding the multi-link impact caused by scheduling through the upper computer.

[0021] Figure 2 It is a schematic diagram of the operating principle of the present invention. DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0023] The first embodiment of the present invention relates to an automatic scheduling method for a relay-type vertical sorting machine, wherein the cargo loading signal is a signal emitted by an electronic component when cargo is present at a pickup position of an elevator car, and the task number is an identification number assigned when the elevator car is in an idle state, and the method comprises the following steps:

[0024] S1. Check: Get the delivery task information and cyclically check whether there is a loading signal at each pickup location;

[0025] S2. Find the task number: For the pickup location with the loading signal, traverse and calculate to find the task number closest to it, and open the synchronization lock for the task number closest to it;

[0026] S3. Issue pickup instruction: Send a pickup instruction to the elevator car corresponding to the task number and simultaneously start the pickup control process, unlock the synchronization lock of the corresponding task number and cancel it; the pickup instruction includes the pickup location and target location;

[0027] S4, automatic transport: The elevator car enters the pickup control process according to the pickup instruction, first moves to the pickup position and stops, then loads the goods, and then the elevator car moves to a relatively close position and stops; the relatively close position is the position closer to the target position and the maximum range position;

[0028] S5. Cargo release reset: If the relative close position is the target position, the cargo will be unloaded; if the relative close position is the maximum range position, the current elevator car will send a cargo signal to wait for other elevator cars to arrive at the unloading position, then receive the cargo, and then move to the initial position and set the task number.

[0029] The second embodiment of the present invention is substantially the same as the first embodiment, mainly in that, during unloading, the drum is opened in the unloading direction until a certain period of time has passed after the loading signal is generated.

[0030] Furthermore, to receive the goods, the drum is opened for a period of time in the down direction.

[0031] Furthermore, before opening the drum, check whether the floor door is open, and if it is not open, an alarm is issued.

[0032] Furthermore, after a period of time, check whether the layer is closed. If it is closed, proceed to the next step. If it is not closed, an alarm is issued.

[0033] Furthermore, loading is carried out by opening the roller in the loading direction to pick up the goods until the loading signal disappears and the goods are empty for a period of time.

[0034] The third embodiment of the present invention is substantially the same as the first embodiment, primarily in that the maximum range position is the furthest position to which the elevator car can travel from the initial position.

[0035] Furthermore, in step S1, when the cargo signal is cyclically checked, the task number is queried at the same time.

[0036] Furthermore, in step S5, after receiving the goods, the other elevator cars send a pickup completion instruction to the current elevator car.

[0037] Based on the above, a typical overall operation mode of the present invention is as follows Figure 1 、 Figure 2 As shown, the details are as follows:

[0038] After the system starts, the primary car T1 task executes: the system automatically checks each elevator car pickup location (or locations) for cargo. When car T1 is idle and cargo is transferred to the car pickup location, the system analyzes the logical information of each pickup location (such as task number, source address, and destination address), compares the task numbers, finds the task with the lowest number among the current pickup locations, and selects this task as the current task to be executed. The tasks to be executed are processed step by step. First, according to the source address information of the task (i.e. the floor address where the goods are located), the address for the car to pick up the goods is issued. After the car receives the pick-up instruction, it automatically runs to the source address of the task. After the car stops, the door opening instruction for the pick-up position is issued. After the floor door is opened, the goods at the pick-up position are transferred to the car through the roller to complete the pick-up. At the same time, the door closing instruction for the pick-up position is issued, the floor door is automatically closed, and the relay elevator T2 is authorized to perform task search; secondly, according to the target address information of the task (i.e. the floor address where the goods are about to be delivered), the address for the car to release the goods is issued. After the car receives the release instruction, it automatically runs to the target address of the task. After the car stops, the goods can be picked up by signaling to T2. When the T2 car runs to the handover position with T1, the goods in the T1 car are transferred to the T2 car through the car roller to complete the delivery. After the task is completed, the relevant information is reset and the next task can be processed.

[0039] After the system is started, the relay car T2 will execute the task: the system will automatically check in a loop whether there is any cargo at the delivery position of car T1. When car T2 is idle and finds that there is cargo at the delivery position of T1, the system will analyze and process the logical information of the cargo at the delivery position (such as task number, source address, and target address), and use this task as the current task to be executed. The tasks to be executed are processed step by step. First, according to the source address information of the parsed task (i.e., the delivery position of T1, which is also the handover position with T2), the car pickup walking address is issued. After receiving the pickup instruction, the car automatically runs to the task source address. After the car stops, it is determined whether T1 has a pickup signal. If there is a pickup signal, the cargo at the delivery position of T1 is transferred to car T2 through the roller to complete the pickup, and the pickup completion instruction is issued at the same time. Secondly, if T2 is the final relay, based on the task's target address (i.e., the floor address where the goods are to be delivered), the elevator car's drop-off location is issued. Upon receiving the drop-off command, the elevator car automatically moves to the task's target address. After the elevator car stops, it issues a door-opening command at the delivery location. Once the floor door opens, the elevator transfers the goods to the target location via the elevator roller, completing the delivery. Simultaneously, a door-closing command is issued at the delivery location, causing the floor door to automatically close. After the task is completed, the relevant information is reset, and the next task can be processed. If there are N relay elevators, the relay elevator T3 is authorized to perform the task search. Thirdly, based on the task's target address (i.e., the floor address where the goods are to be delivered), the elevator car's drop-off location is issued. Upon receiving the drop-off command, the elevator car automatically moves to the task's target address. After the elevator car stops, a pickup signal is sent to T3. When T3 reaches the handover position with T2, the goods in T2 are transferred to T3 via the elevator roller, completing the delivery. After the task is completed, the relevant information is reset, and the next task can be processed. If there are N relay cars, the relay transmission will continue according to this rule until it reaches the final target floor position.
