Technical Field

[0001] The present invention relates to the technical field of logistics management, and in particular to a control method and device for a material transportation system, a material transportation system and a medium. Background Art

[0002] With the rapid development of the economy and the continuous changes in consumption patterns, the logistics and warehousing industries are facing increasing challenges. In order to meet consumers' demand for fast, accurate and efficient logistics services, companies need to improve the automation and intelligence level of logistics and warehousing. As a key link in the logistics and warehousing process, the performance and efficiency of the sorting system directly affect the operation of the entire logistics chain. Therefore, improving logistics efficiency is particularly important.

[0003] The existing technology often uses a single-layer elevator to transport materials. The single-layer elevator is fed from the conveyor line that issues the request and transports the materials to the specified location. However, there are many conveyor lines in logistics and warehousing. The above method requires the elevator to frequently travel between different conveyor lines, which has low transportation efficiency and high energy consumption. Summary of the invention

[0004] In view of this, the present invention provides a control method, device, material transportation system and medium for a material transportation system to solve the problem that the prior art requires a single-layer elevator to frequently travel back and forth between different conveyor lines, resulting in low transportation efficiency and high energy consumption costs.

[0005] In a first aspect, the present invention provides a control method for a material transportation system, the system comprising a multi-layer elevator, a conveyor line group, and a lifting channel running through the conveyor line group up and down, wherein the conveyor line group comprises a plurality of conveyor lines spaced apart in the up and down directions, the multi-layer elevator comprises at least a first cargo platform and a second cargo platform spaced apart in the up and down directions; the multi-layer elevator moves up and down in the lifting channel, the height difference between two adjacent cargo platforms is consistent with the height difference between two adjacent conveyor lines, and the method applied to the multi-layer elevator comprises:

[0006] When a signal indicating that there is cargo and a request for feeding are detected on the first conveying line, the multi-storey elevator is controlled to move to a position where the first cargo platform is aligned with the height of the first conveying line, and the cargo is received by using the first cargo platform;

[0007] Determine a second conveyor line that is aligned with the second cargo platform in height, and if it is detected that the second conveyor line sends a cargo signal and a feed request, use the second cargo platform to receive the cargo;

[0008] Determine the destination conveying lines corresponding to the goods on the first cargo platform and the goods on the second cargo platform respectively, and control the multi-layer elevator to transport the goods on the first cargo platform and the goods on the second cargo platform to the destination conveying lines.

[0009] Beneficial effects: When the present invention detects the cargo signal and feed request of the first conveyor line, it controls the first loading platform of the multi-layer elevator to dock at the first conveyor line to load and receive the cargo. The height difference between two adjacent loading platforms of the multi-layer elevator is set to be consistent with the height difference between two adjacent conveyor lines, so that the second loading platform is highly aligned with the second conveyor line, which is convenient for receiving the cargo of the second conveyor line using the second loading platform. In this way, the multi-layer elevator can meet the feeding needs of multiple conveyor lines in one receiving process, load as much cargo as possible, thereby improving transportation efficiency and reducing energy consumption, and finally transporting the cargo to the corresponding destination conveyor line to realize the transportation of material layer change. In addition, material layer change transportation can be realized without installing a layer cutting mechanism, reducing the system installation cost.

[0010] In some optional embodiments, after determining the second conveyor line aligned with the height of the second cargo platform, the method further includes:

[0011] If it is detected that the second conveyor line has not issued a signal of goods and a request for feeding, the multi-storey elevator is controlled to move to a position where the second cargo platform is aligned with the height of the third conveyor line;

[0012] If it is detected that the third conveyor line sends a signal of goods being present and a request for feeding, the second loading platform is used to receive the goods from the third conveyor line.

[0013] Beneficial effect: When the present invention controls the multi-storey elevator to move to a position where the first cargo platform is highly aligned with the first conveyor line, if the second conveyor line currently aligned with the second cargo platform has no demand for goods, the elevator will continue to be controlled to move so that the second cargo platform will be docked on the conveyor line with demand for goods, thereby realizing the loading of goods on the multi-storey elevator and improving transportation efficiency.

[0014] In some optional embodiments, controlling the multi-layer elevator to transport the first cargo platform cargo and the second cargo platform cargo to the destination conveying line includes:

[0015] When it is detected that the multi-storey elevator moves to a position where the first cargo platform or the second cargo platform is aligned with the height of any conveyor line, a fourth conveyor line aligned with the height of the first cargo platform and a fifth conveyor line aligned with the height of the second cargo platform are determined;

[0016] If it is detected that the fourth conveyor line is the destination conveyor line for the goods on the first cargo platform, the goods on the first cargo platform are transported to the fourth conveyor line;

[0017] And / or, if it is detected that the fifth conveyor line is the destination conveyor line for the goods on the second cargo platform, the goods on the second cargo platform are transported to the fifth conveyor line.

[0018] Beneficial effect: When the embodiment of the present invention detects that the multi-layer elevator moves to a position where the first cargo platform or the second cargo platform is highly aligned with any conveyor line, it will detect whether there is a destination conveyor line for the cargo platform's goods in the conveyor line currently aligned with the cargo platform. If so, the goods will be directly transported to the corresponding destination conveyor line to avoid the elevator moving to other conveyor lines and then returning to the current conveyor line to unload the goods, thereby saving the elevator's moving time and improving material transportation efficiency.

[0019] In some optional embodiments, when it is detected that the multi-storey elevator moves to a position where the first cargo platform is aligned with the first conveyor line in height, determining a fourth conveyor line aligned with the first cargo platform in height and a fifth conveyor line aligned with the second cargo platform in height includes:

[0020] Determine a conveyor line other than the first conveyor line that is aligned with the height of the first cargo platform as the fourth conveyor line; wherein the first conveyor line and the fourth conveyor line are respectively located on both sides of the same height of the lifting pipeline;

[0021] The conveying line other than the second conveying line that is aligned with the height of the second cargo platform is determined as the fifth conveying line; wherein the second conveying line and the fifth conveying line are respectively located on both sides of the same height of the lifting pipeline.

[0022] Beneficial effect: When the present invention detects that the multi-story elevator has moved to the position where the first cargo platform is aligned in height with the first conveyor line, it determines whether there is a destination conveyor line among the fourth conveyor line aligned in height with the first cargo platform and the fifth conveyor line aligned in height with the second cargo platform. When it is detected that the fourth conveyor line and / or the fifth conveyor line are the destination of the goods, the corresponding goods are directly transported to the fourth conveyor line and / or the fifth conveyor line, avoiding the elevator moving to other conveyor lines and then returning to the current conveyor line to unload the goods, thereby reducing the number of times the elevator moves and improving material transportation efficiency.

[0024] When it is detected that the cargo photoelectric signal of any conveyor line sends out the cargo signal and the material-in-place photoelectric signal sends out the material-feeding request, the destination of the cargo of the corresponding conveyor line is obtained according to the cargo signal and the material-feeding request.

[0025] Beneficial effect: After receiving the cargo signal and feed request, the multi-storey elevator of the present invention analyzes them to obtain the destination of the cargo in the feed request, which is convenient for guiding the movement process and path planning of the multi-storey elevator, so as to transport the cargo to the target conveyor line and ensure smooth material supply in production, warehousing and other links.

[0030] In some optional embodiments, the lifting channel is provided with a plurality of groups of deceleration photoelectric and in-position photoelectric, and the position of each group of deceleration photoelectric and in-position photoelectric corresponds to the height of the corresponding conveyor line; controlling the multi-layer elevator to move to a position where the first cargo platform is aligned with the height of the first conveyor line includes:

[0031] In the process of controlling the multi-storey elevator to move up and down, if a deceleration signal is detected from the deceleration photoelectric corresponding to the first conveying line, the multi-storey elevator is controlled to decelerate;

[0032] When the arrival signal emitted by the arrival photoelectric device corresponding to the first conveying line is detected, the multi-layer elevator is controlled to stop moving.

[0033] Beneficial effect: The present invention sets deceleration photoelectric and arrival photoelectric at the corresponding height of each conveyor line, and controls the multi-layer elevator to decelerate after receiving the deceleration signal of the photoelectric, so that the multi-layer elevator can be smoothly and accurately moved when reaching the height position of the conveyor line, thereby avoiding collision due to excessive speed, preventing damage to the elevator and goods, and ensuring the transportation quality of goods.

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0050] In order to meet consumers' demand for fast, accurate and efficient logistics services, enterprises need to improve the automation and intelligence level of logistics and warehousing. The relevant technology requires single-layer elevators to frequently travel between different conveyor lines, which has low transportation efficiency and high energy consumption costs.

[0051] Therefore, the embodiment of the present invention provides a control method for a material transportation system, which uses a multi-layer elevator to transport materials, quickly and accurately transports items to a designated location, and improves the efficiency and accuracy of logistics operations. Transportation companies using multi-layer elevators can greatly improve transportation efficiency, reduce costs and energy consumption, and thus obtain higher economic benefits.

[0052] According to an embodiment of the present invention, a material transportation system is provided. Figure 1 As shown, the material transportation system includes a multi-layer elevator 101, a conveyor line group 102 and a lifting channel 103 that runs through the conveyor line group 102 from top to bottom, wherein the conveyor line group 102 includes a plurality of conveyor lines spaced apart in the vertical direction, and the multi-layer elevator 101 includes at least a first cargo platform and a second cargo platform spaced apart in the vertical direction.

[0053] It should be noted that the multi-layer elevator 101 moves up and down in the lifting channel, and the height difference between two adjacent cargo platforms is consistent with the height difference between two adjacent conveyor lines, ensuring that when the multi-layer elevator 101 stops in the lifting channel 103, each cargo platform can be aligned with the conveyor line at the corresponding height.

[0054] Specifically, the multi-storey elevator 101 is used to: when detecting the cargo signal and feed request of the first conveyor line, control the multi-storey elevator 101 to move to the position where the first cargo platform is highly aligned with the first conveyor line, and use the first cargo platform to receive the cargo; determine the second conveyor line that is highly aligned with the second cargo platform, and if it is detected that the second conveyor line sends a cargo signal and a feed request, use the second cargo platform to receive the cargo; determine the destination conveyor lines corresponding to the cargo on the first cargo platform and the cargo on the second cargo platform, respectively, and control the multi-storey elevator 101 to transport the cargo on the first cargo platform and the cargo on the second cargo platform to the destination conveyor lines.

[0055] The detailed working principle and control process of the multi-storey elevator 101 are described in detail in the specific description of the method embodiment below, which will not be repeated here.

[0056] According to an embodiment of the present invention, an embodiment of a control method for a material transportation system is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0057] In this embodiment, a control method for a material transportation system is provided, which can be used for example Figure 1 The multi-layer elevator 101 shown, such as a double-layer elevator, a triple-layer elevator, etc., Figure 2 is a flow chart of a control method of a material transportation system according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0058] Step S201, when detecting the cargo signal and feed request of the first conveyor line, controlling the multi-storey elevator to move to a position where the first cargo platform is aligned with the height of the first conveyor line, and using the first cargo platform to receive the cargo.

[0059] In some optional embodiments, the lifting channel is provided with multiple groups of deceleration photoelectric and in-position photoelectric, and the position of each group of deceleration photoelectric and in-position photoelectric corresponds to the height of the corresponding conveyor line. In the process of controlling the up and down movement of the multi-layer elevator, if a deceleration signal is detected from the deceleration photoelectric corresponding to the first conveyor line, the multi-layer elevator is controlled to decelerate, and when an in-position signal is detected from the in-position photoelectric corresponding to the first conveyor line, the multi-layer elevator is controlled to stop moving.

[0060] Specifically, the deceleration photoelectric sensor is used to send a deceleration signal to the controller of the elevator when the elevator approaches the corresponding conveyor line during the operation of the elevator, so that the elevator starts to decelerate. The in-place photoelectric sensor is used to detect whether the elevator has accurately reached the corresponding height of the conveyor line. It can provide an accurate in-place signal to the controller of the elevator, indicating that the elevator has reached the expected height, thereby triggering subsequent operations, etc. Photoelectric devices such as deceleration photoelectric sensors and in-place photoelectric sensors generally work by emitting and receiving light. When an object blocks the light, the photoelectric sensor will detect the signal change.

[0061] The present invention arranges deceleration photoelectric devices and arrival photoelectric devices at the corresponding height of each conveyor line, and controls the multi-storey elevator to decelerate after receiving the deceleration signal of the photoelectric devices, so that the multi-storey elevator can be smoothly and accurately moved when reaching the height position of the conveyor line, thereby avoiding collision due to excessive speed, preventing damage to the elevator and goods, and ensuring the transportation quality of the goods.

[0062] Step S202, determining the second conveyor line that is highly aligned with the second cargo platform, and if it is detected that the second conveyor line sends a cargo signal and a feed request, the second cargo platform is used to receive the cargo.

[0063] Specifically, since the height difference between the first cargo platform and the second cargo platform is consistent with the height difference between the first conveyor line and the second conveyor line, when the multi-storey elevator stops at the position where the first cargo platform is aligned with the height of the first conveyor line, the height of the second cargo platform of the multi-storey elevator is also aligned with the height of the second conveyor line, so that the cargo of the second conveyor line can be loaded onto the second cargo platform.

[0064] It should be noted that the number of cargo platforms of a multi-storey elevator can be three or more. As long as the height difference is consistent, the cargo platform can be aligned with the height of the corresponding conveyor line during each stop of the elevator. In this way, the multi-storey elevator can meet the feeding needs of multiple conveyor lines in one receiving process and load as much cargo as possible, thereby improving transportation efficiency.

[0065] Step S203, determining the destination conveying lines corresponding to the goods on the first cargo platform and the goods on the second cargo platform respectively, and controlling the multi-layer elevator to transport the goods on the first cargo platform and the goods on the second cargo platform to the destination conveying lines.

[0066] Specifically, after determining the destination of the cargo on each cargo platform, each time the multi-layer elevator stops, it can be detected whether there is a destination conveyor line in the conveyor line currently aligned with the height of the cargo platform. If so, unloading can be carried out directly to realize material transportation.

[0067] The control method of the material transportation system provided in this embodiment controls the first loading platform of the multi-layer elevator to dock at the first conveyor line to load and receive goods when the cargo signal and feed request of the first conveyor line are detected. The height difference between two adjacent loading platforms of the multi-layer elevator is set to be consistent with the height difference between two adjacent conveyor lines, so that the second loading platform is aligned with the height of the second conveyor line, which is convenient for receiving the goods of the second conveyor line using the second loading platform. In this way, the multi-layer elevator can meet the feeding needs of multiple conveyor lines in one receiving process, load as much goods as possible, thereby improving transportation efficiency and reducing energy consumption, and finally transporting the goods to the corresponding destination conveyor line to realize the transportation of material layer change. In addition, material layer change transportation can be realized without installing a layer cutting mechanism, which reduces the system installation cost.

[0068] In this embodiment, a control method for a material transportation system is provided, which can be used for example Figure 1 The multi-layer elevator 101 shown, such as a double-layer elevator, a triple-layer elevator, etc., Figure 3 is a flow chart of a control method for a material transportation system according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0069] Step S301, when detecting the signal of cargo presence and the feeding request of the first conveyor line, control the multi-storey elevator to move to the position where the first cargo platform is aligned with the height of the first conveyor line, and use the first cargo platform to receive cargo. Figure 2 The description of step S201 of the illustrated embodiment will not be repeated here.

[0070] Step S302, determining the second conveyor line that is highly aligned with the second cargo platform, and if it is detected that the second conveyor line sends a cargo signal and a feed request, the second cargo platform is used to receive the cargo.

[0071] In some optional embodiments, if it is detected that the second conveyor line has not issued a signal of cargo and a request for feeding, the multi-layer elevator is controlled to move to a position where the second loading platform is aligned with the height of the third conveyor line. If it is detected that the third conveyor line has issued a signal of cargo and a request for feeding, the second loading platform is used to receive the cargo of the third conveyor line. It should be noted that the third conveyor line can be a conveyor line located on the lower layer of the second conveyor line and adjacent to the second conveyor line. The elevator is first controlled to move to the third conveyor line, and then the signal of cargo and the request for feeding are detected. This can not only simplify the control process, but also allow the elevator to pass through as many conveyor lines as possible during the up and down movement of the elevator, so as to quickly load the cargo on the second loading platform.

[0072] In addition, the third conveyor line can also be any conveyor line except the first conveyor line and the second conveyor line. It can also first detect which conveyor line has sent a goods signal and a feed request, and then control the second cargo platform to be highly aligned with the corresponding conveyor line. This method can reduce the waiting time of the conveyor line and quickly meet the purchase needs of the corresponding conveyor line.

[0073] When the present invention controls the multi-story elevator to move to a position where the first cargo platform is highly aligned with the first conveyor line, if the second conveyor line currently aligned with the second cargo platform has no demand for goods, the elevator continues to be controlled to move so that the second cargo platform stops at the conveyor line with demand for goods, thereby realizing cargo loading of the multi-story elevator and improving transportation efficiency.

[0074] Step S303, determining the destination conveying lines corresponding to the goods on the first cargo platform and the goods on the second cargo platform respectively, and controlling the multi-layer elevator to transport the goods on the first cargo platform and the goods on the second cargo platform to the destination conveying lines.

[0075] Specifically, the above step S303 includes:

[0076] Step S3031, determining the destination conveying lines corresponding to the goods on the first loading platform and the goods on the second loading platform respectively.

[0077] In some optional embodiments, each conveyor line is equipped with a cargo photoelectric indicator and a material in place photoelectric indicator. When it is detected that the cargo photoelectric indicator of any conveyor line sends a cargo signal and the material in place photoelectric indicator sends a feed request, the destination of the cargo of the corresponding conveyor line is obtained based on the cargo signal and the feed request.

[0078] Specifically, after receiving the cargo signal and feed request, the multi-storey elevator will analyze it to obtain the destination of the cargo in the feed request, so as to guide the movement process and path planning of the multi-storey elevator, so as to transport the cargo to the target conveyor line and ensure smooth material supply in production, warehousing and other links.

[0079] Furthermore, the multi-story elevator can obtain the destination conveyor line corresponding to the first cargo platform's cargo according to the destination of the cargo on the first conveyor line, and obtain the destination conveyor line corresponding to the second cargo platform's cargo according to the destination of the cargo on the second conveyor line or the third conveyor line. Thus, based on the destination of the cargo on the corresponding conveyor line obtained through analysis, the final destination of the multi-story elevator in a material transportation process can be determined, thereby transporting the cargo on the cargo platform to the target conveyor line, realizing layer-changing transportation of materials and improving transportation efficiency.

[0080] Step S3032, when it is detected that the multi-storey elevator moves to a position where the first cargo platform or the second cargo platform is aligned with the height of any conveyor line, determine the fourth conveyor line aligned with the height of the first cargo platform and the fifth conveyor line aligned with the height of the second cargo platform.

[0081] In some optional embodiments, a conveyor line other than the first conveyor line that is aligned with the height of the first cargo platform is determined as the fourth conveyor line, and a conveyor line other than the second conveyor line that is aligned with the height of the second cargo platform is determined as the fifth conveyor line. The first conveyor line and the fourth conveyor line are respectively located on both sides of the same height of the lifting pipeline, and the second conveyor line and the fifth conveyor line are respectively located on both sides of the same height of the lifting pipeline.

[0082] Specifically, see again Figure 1 Since the lifting pipe for the elevator to move up and down runs through the conveyor line group from top to bottom, there are conveyor lines on both sides of the lifting pipe. In this way, every time the elevator stops, at least two conveyor lines are aligned with the height of a certain layer of the cargo platform. One of these two conveyor lines may be the conveyor line for sending goods, and the other may be the conveyor line for the destination of the goods.

[0083] That is to say, when the multi-storey elevator stops at the position where the first cargo platform is aligned with the first conveyor line in height, the fourth conveyor line located on the other side of the lifting pipe will be aligned with the first cargo platform. Due to the consistent height difference, the second conveyor line and the fifth conveyor line will be aligned with the second cargo platform, except that the second conveyor line and the fifth conveyor line are located on both sides of the same height of the lifting pipe.

[0084] Therefore, when the embodiment of the present invention detects that the multi-story elevator has moved to the position where the first cargo platform is highly aligned with the first conveyor line, it determines whether there is a destination conveyor line among the fourth conveyor line aligned with the first cargo platform and the fifth conveyor line aligned with the second cargo platform. When it is detected that the fourth conveyor line and / or the fifth conveyor line are the destination of the goods, the corresponding goods are directly transported to the fourth conveyor line and / or the fifth conveyor line, avoiding the elevator moving to other conveyor lines and then returning to the current conveyor line to unload the goods, thereby reducing the number of times the elevator moves and improving material transportation efficiency.

[0085] Step S3033, if it is detected that the fourth conveyor line is the destination conveyor line for the goods on the first cargo platform, the goods on the first cargo platform are transported to the fourth conveyor line, and / or, if it is detected that the fifth conveyor line is the destination conveyor line for the goods on the second cargo platform, the goods on the second cargo platform are transported to the fifth conveyor line.

[0086] When the embodiment of the present invention detects that the multi-layer elevator moves to a position where the first cargo platform or the second cargo platform is highly aligned with any conveyor line, it will detect whether there is a destination conveyor line for the cargo platform's goods in the conveyor line currently aligned with the cargo platform. If so, the goods will be directly transported to the corresponding destination conveyor line to avoid the elevator moving to other conveyor lines and then returning to the current conveyor line to unload the goods, thereby saving the elevator's movement time and improving material transportation efficiency.

[0087] The following takes the multi-layer elevator as a double-layer elevator as an example, and describes in detail the control method of the material transportation system of the present invention in combination with a specific application example. Figure 4 As shown, in the material transportation system of this application example, conveyor lines A1, A2, B1, B2, C1, and C2 are high-altitude conveyor lines, among which A1, A2, B1, and B2 are used to transport goods to the ground material port. A1 and A2 are 4 meters from the ground, B1 and B2 are 3.4 meters from the ground, and C1 and C2 are 2.8 meters from the ground.

[0088] See again Figure 4 Conveyor lines D1, D2, E1, and E2 are ground conveyor lines. D1 and D2 are 1.3 meters from the ground, and E1 and E2 are 0.7 meters from the ground. High-altitude materials are transported by high-altitude conveyor lines A1, B1, and C1 to conveyor lines A2, B2, and C2 or D1, E1 or D2, and E2. Ground materials are transported by D1, E1 or D2, and E2 to A2, B2, and C2 in the air.

[0089] The optoelectronic layout of the material transportation system provided in this application example is as follows Figure 5 As shown, a1, a2, b1, b2, c1, c2, d1, d2, e1, e2 are the corresponding conveyor line's cargo photoelectrics, which are used to determine whether the conveyor line has cargo; a3, b3, c3, d3, d4, e3, e4 are the corresponding conveyor line's feeding in place photoelectrics, which are used to stop the cargo and determine whether the conveyor line has feeding application; 2, 4, 5, 8, 9, 12, 13, 15 are the deceleration photoelectrics of the double-layer elevator's in place photoelectrics, 1, 3, 6, 7, 10, 11, 14, 16 are the double-layer elevator's in place photoelectrics, and in place photoelectrics can also be set in the elevator's cargo platform. The function of the photoelectrics at 15.16 is to transport the material on the highest floor to the lowest floor, and to transport the material on the lowest floor to the highest floor.

[0090] When a1 has a signal of cargo and a3 has a request for feeding, if the elevator is idle, the upper loading platform of the elevator will slow down from 2 and stop at 1 photoelectric position, and cargo A1 will enter the upper loading platform. At the same time, it is determined whether b1 has a signal of cargo and a request for feeding from b3. If so, cargo B1 will enter the lower loading platform of the elevator together; if not, it is determined whether cargo A1 is going to A2. If so, cargo A1 on the upper loading platform will directly enter A2. If not, it is determined whether c1 has a signal of cargo and a request for feeding from c3.

[0091] If c1 has a signal of goods and c3 has a request for feeding, the lower loading platform will slow down from 5 and stop at 6 photoelectric position, and the C1 goods will enter the lower loading platform of the elevator. At this time, it is judged whether the destination of A1 goods is B2 and whether the destination of C1 goods is C2. If one of them is satisfied, the materials on this layer will be sent out first; if neither of them is satisfied, it is judged whether the destination of C1 goods is D1 or D2. If so, the lower loading platform will slow down from 9 and stop at 10 photoelectric position. If not, it is judged whether the destination of A1 goods is D1, D2 and whether the destination of C1 goods is E1, E2. If one of them is satisfied, the lower loading platform will slow down from 13 and stop at 14 photoelectric position to send out the materials on this layer first; if A1 is going to E1, E2, the lower loading platform will slow down from 15 and stop at 16 photoelectric position, and the materials of A1, B1 and C1 have been sent out.

[0092] When there is a signal of cargo in d1 and d2 and a request for feeding in d3 and d4, it is determined whether the destination of the material is A2. If so, the material is placed on the upper loading platform of the elevator. At the same time, it is determined whether there is a request for feeding in the lower level where the elevator is located. If so, the upper and lower levels are fed at the same time, that is, it is determined whether there is a signal of cargo in e1 and e2 and whether there is a request for feeding in e3 and e4. If so, the material is placed on the lower level. Then, the elevator transports the material to the aerial conveyor lines A1, B1, and C1. Similarly, if there is a situation where B1 transports materials to A2 and C1 transports materials to A1, when the elevator is transporting upwards, it should first be determined whether the above two situations exist. If so, the material should be transported to the elevator first, that is, the material should be transported to the upper loading platform.
