There is also a technology that sets a separate sorting trolley for each layer of the collection basket of the sorting shelf, and uses an elevator to supply goods to the sorting trolley on each layer. In this solution, the elevator can only supply goods to the sorting trolley on one layer at a time, and the efficiency is still low. Utility Model Content

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-2 The efficient logistics sorting system shown in the figure comprises a multi-layered sorting device A, and also comprises an elevator B capable of transporting goods to each of the sorting devices A; the sorting device A comprises a delivery unit 1, and the delivery unit 1 runs along a delivery path 2, and a cargo placement unit 3 is arranged on the side of the delivery path 2; Figure 3 As shown, the elevator B has multiple supply units 4 that are aligned vertically and staggered in the vertical direction, so that the elevator B can supply multiple sorting devices A at the same time. Therefore, the elevator B can supply multiple sorting devices A at the same time, effectively improving the sorting efficiency. Since all the supply units 4 are aligned vertically, the space required for the lifting of multiple supply units 4 can be reduced, and the space required for the operation of the efficient logistics sorting system can be reduced; it also includes an input device 5 with a fixed vertical position, and the input device 5 can transfer goods to the supply unit 4. Since the position of the input device 5 is fixed, the staff or the sorting machine can load the goods at a fixed point, that is, place the goods on the input device 5, wait for the supply unit 4 to be aligned with the input device 5, and transfer the goods between the input device 5 and the supply unit 4, which can reduce the difficulty of loading goods and reduce risks.

[0020] Preferably, the relative positions of all the supply units 4 are fixed, the supply units 4 move up and down synchronously, and the spacing between adjacent supply units 4 is equal to the spacing between adjacent sorting devices A, so that the structural complexity and driving difficulty can be reduced, and all the supply units 4 can be lifted and lowered as a whole. In other embodiments, each supply unit 4 can also move up and down separately, and each supply unit 4 has a lifting drive device.

[0021] Preferably, all the supply units 4 are mounted on a lifting frame 6, and the lifting frame 6 is driven by a driving device to perform lifting motion.

[0022] Preferably, the input device 5 is equipped with a cargo information acquisition device, which may be a barcode scanner that can acquire identifiable codes such as barcodes and QR codes on commodities or express delivery. The cargo information acquisition device may also be an RFID scanner that can acquire label information of an RFID label pre-placed on the cargo, and the cargo information acquisition device may also be in other forms.

[0023] Preferably, the number of input devices 5 can be one, preferably, the number of input devices 5 is multiple, all the input devices 5 are staggered in the vertical direction, and the multiple input devices 5 can simultaneously supply goods to the same number of supply units 4. In this way, the supply efficiency can be improved, and each input device 5 has a goods information acquisition device.

[0024] Preferably, a shelf 7 is installed on one side of the sorting device A, and the cargo unit 3 is a cargo container placed on the shelf 7, and the cargo unit 3 can be disassembled and replaced relative to the shelf 7. During operation, the control system will assign a sorting task to each cargo unit 3, and the sorting task is generally an order task, or a classification task, and the following description will be based on the order task. The order task contains one or more target goods. When all the goods are collected in the cargo unit 3, the sorting task corresponding to the cargo unit 3 is completed, and the cargo unit 3 can be removed and an empty cargo unit 3 can be placed.

[0025] An efficient logistics sorting method, which is based on the above-mentioned efficient logistics sorting system, is implemented by a control system capable of controlling the operation of the elevator B and scheduling the movement of the delivery unit 1. The method includes the following steps S101-S104 (the step numbers are not used to limit the order of implementation of the steps):

[0026] Step S101, allocating the cargo placement unit 3 to a sorting task; a sorting task is generally an order task or a classification task, such as classifying express delivery by region.

[0027] Step S102, obtaining information of the goods to be sorted on the input device 5; based on the information of the goods to be sorted, the sorting task to which the goods to be sorted belong can be known. Here, the form of the goods to be sorted is not limited, and can be specific commodities, parts, express delivery, parcels, etc.

[0028] Step S103, driving the supply unit 4 of the elevator B to move upward and downward, so that the supply unit 4 receives the goods to be sorted from the input device 5, and distributes the goods to be sorted received from the input device 5 to the sorting device A at the target layer;

[0029] Step S104 , the delivery unit 1 of the sorting device A receives the goods to be sorted provided by the supply unit 4 , moves along the delivery path 2 to the storage unit 3 corresponding to the goods to be sorted, and delivers the goods to be sorted to the storage unit 3 .

[0030] Preferably, in this embodiment, when the lifting frame 6 is raised to the top, the supply unit 4 at the top corresponds to the sorting device A at the top, that is, only the supply unit 4 at the top can supply the sorting device A at the top, and so on, the two supply units 4 at the top can both supply the second sorting device A from the top downward, and the three supply units 4 at the top can both supply the third sorting device A from the top downward. Based on this, the above step S102 of making each supply unit 4 receive the goods to be sorted from the input device 5 includes the following steps s201-S203:

[0031] Step S201, obtaining the target layer corresponding to the goods to be sorted according to the information of the goods to be sorted on the input device 5;

[0032] Step S202, obtaining a first judgment result according to whether the supply unit 4 corresponding to the target layer is in an empty state;

[0033] Step S203, when the first judgment is no, after at least one of the supply units 4 corresponding to the target layer outputs the goods to be sorted, the elevator B is controlled to operate so that the supply unit 4 corresponding to the target layer docks with the input device 5 for the goods to be sorted.

[0034] Preferably, the control system reads the information of a plurality of consecutive goods to be sorted, and the step S103 described in which the supply unit 4 receives the goods to be sorted from the input device 5 and distributes the goods to be sorted received from the input device 5 to the sorting device A at the target layer includes:

[0035] Determine whether there is a situation that satisfies the following conditions at the same time: behind the goods to be sorted that are about to be output, there is at least one goods to be sorted that is consistent with its target layer, and there are multiple idle supply units 4 that can reach the target layer; if so, make the continuous goods to be sorted corresponding to the same target layer reach the same number of supply units 4; here, there can be goods that reach other target layers between the goods to be sorted corresponding to the same target layer, as long as the elevator B has enough supply units 4 to accommodate at least two adjacent goods to be sorted corresponding to the same target layer and the goods that reach other target layers that may be located between these goods to be sorted. For example, the target layers of three consecutive goods to be sorted are 3, 2, and 3, respectively, and the elevator B needs to have three empty supply units 4. In this case, multiple supply units 4 play a role of cache, realizing continuous supply to the same sorting device A, which can reduce the number of round trips.

[0036] It is determined whether there are multiple goods to be sorted with different target floors, and there are multiple vacant supply units 4 on the elevator B that meet the target floor layout; if yes, the goods to be sorted are respectively delivered to the supply units 4 according to the target floor layout. For example, if the target floors of three consecutive goods are 3, 4, and 5, respectively, and there are three consecutive vacant supply units 4 on the elevator B, the three consecutive goods to be sorted are arranged in order from bottom to top. The above situation is not limited to continuous goods to be sorted, but can also be two goods to be sorted separated by other goods to be sorted, such as three continuous goods to be sorted whose target layers are 2, 5, and 4 respectively, wherein the layout feature of the two goods to be sorted whose target layers are 2 and 4 is that there is one layer between them, wherein the elevator B has three empty supply units 4, and two supply units 4 meet the above layout feature, then the two goods to be sorted whose target layers are 2 and 4 are respectively transported to the two supply units 4 that meet the layout feature, and the other goods to be sorted, here the goods to be sorted whose target layer is 5, are transported to the other empty supply units 4. In this case, when the lifting frame 6 is parked at one position, it can realize the simultaneous supply of multiple pairs of sorting devices A, thereby improving the supply efficiency.

[0037] By adopting the above-mentioned sorting method, the supply buffer can be performed on the same sorting device A as needed, and multiple sorting devices A can be supplied at the same time, thereby reducing the moving stroke of the lifting frame 6 and improving the sorting efficiency.

[0038] Preferably, in a preferred solution, the step S013 described in which the supply unit 4 receives the goods to be sorted from the input device 5 and delivers the goods to be sorted received from the input device 5 to the sorting device A at the target layer includes:

[0039] The running distance and the number of tasks corresponding to each docking scheme of the lifting frame 6 when the number of docking times N is less than the preset number are counted, and the optimal docking scheme is selected based on multiple factors including the number of docking times, the running distance and the number of tasks. The above preset number is less than the total number of supply units 4. The number of tasks is the total number of input tasks (the input device 5 delivers the goods to be sorted to the supply unit 4) and output tasks (the supply unit 4 delivers the goods to be sorted to the delivery unit 1) that can be performed.

[0040] Specifically, the above-mentioned docking scheme is that the lifting frame 6 docks at a different height each time in N times, and each docking position has a scheme in which an input task or an output task can be implemented.

[0041] The optimal docking scheme is selected based on a variety of factors including the number of stops, the running distance and the number of tasks. Specifically, the docking scheme is selected as the optimal docking scheme according to the principle of fewer stops, shorter running distance and more tasks. When the number of stops is the same: if the running distance is the same, the docking scheme with more executable tasks is selected; if the number of executable tasks is the same, the docking scheme with shorter running distance is selected. When the number of stops is different: the number of stops and the running distance can be unified by running time, that is, the time required for each stop handover and the time required for the lifting distance of the lifting frame 6 to rise and fall corresponding to the running distance are determined to calculate the total running time. The number of stops and the running distance can be combined, and then the average time spent on each executable task is calculated based on the total running time and the number of executable tasks, and the docking scheme with short average time is preferentially selected.

[0042] In addition, the optimal docking scheme can also be selected based on the principle of reducing the number of detentions. The number of detentions is used to count the detention time of the goods to be sorted on the supply unit 4. Each time the supply unit 4 stops at a position and the goods to be sorted are not output, the number of detentions of the goods to be sorted is increased by 1. When the goods that have been detained for many times are delivered, the total number of detentions of the corresponding goods to be sorted on the supply unit 4 can be greatly reduced. In this way, the delivery of the detained goods can be guaranteed to have priority, preventing the goods from being delayed in delivery. In actual operation, the priority of the number of detentions, the shortest running distance, and the average time spent on each executable task can be set as needed to determine the optimal docking scheme.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
