[0070] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0071] With the continuous development of the logistics industry, the requirements for item sorting in logistics centers are also getting higher and higher.

[0072] Currently, items are identified by manual recognition or an automated system to achieve the sorting operation of items.

[0073] However, such item sorting operations have low efficiency.

[0074] In order to overcome the defects in the prior art, the present application provides a sorting system, including a track device, an adjustment device and a transfer device.

The transfer device is movably located in the first channel and the second channel, respectively, and the transfer device loads corresponding articles and delivers the articles to the corresponding sorting positions. The adjustment devices are respectively connected to the two ends of the track device. When the transfer device moves to the end of the guide rail, the transfer device moves to the guide rails of other layers through the adjustment device, thereby realizing the movement of the transfer device on the guide rails of each layer of the track device, and delivering the articles to different sorting positions of the track device. Through such a sorting system, accurate sorting of articles is achieved, and the efficiency of sorting operations of articles is improved.

[0075] The contents of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application more clearly and in detail.

Figure 7 for Figure 6 A partial enlarged view of the dotted box part.

[0077] like Figures 1 - 7 As shown, an embodiment of the present application provides a sorting system 100 , including: a track device 110 , an adjustment device 130 and at least two transfer devices 120 .

[0078] The track device 110 includes at least two stacked guide rails 111 , the guide rail 111 has a first channel 112 and a second channel 113 adjacent to each other, and a sorting position 114 is provided on the side of the first channel 112 and the second channel 113 facing away from each other.

[0079] At least two transfer devices 120 are movably located in the first channel 112 and the second channel 113 ; the transfer devices 120 are configured to load items and deliver the items to the sorting position 114 .

[0080] The adjusting devices 130 are respectively connected to two ends of the track device 110 .

[0081] When the transfer device 120 moves to the end of the guide rail 111 , the transfer device 120 moves to the guide rail 111 of another layer through the adjustment device 130 .

[0082] According to the sorting system 100 provided in the embodiment of the present application, the track device 110 has multiple layers of guide rails 111, each layer of guide rails 111 has and adjacent first channels 112 and second channels 113, the transfer device 120 can load items and move in the first channel 112 and the second channel 113 at the same time, and deliver the items to the sorting position 114 on the side opposite to the first channel 112 and the second channel 113, the number of items that the sorting system 100 can sort is increased, and the efficiency of the sorting operation of the sorting system 100 for items is improved. At the same time, the transfer device 120 moves to the guide rails 111 of other layers through the adjustment device 130, realizing the sorting and delivery operation of items in the track devices 110 of different layers of the track device 110, and improving the efficiency of the sorting operation of items.

[0083] The specific structure of the sorting system 100 and various possible implementations are described in detail below.

[0084] It should be noted that the articles in this embodiment may be goods, or express parcels, etc. For example, the goods may be beverages, daily necessities, etc. packaged in packages or boxes.

[0085] It can be understood that the track device 110 includes at least two layers of stacked guide rails 111. Of course, the number of guide rails 111 can also be three, four or more layers. The multiple layers of guide rails 111 can be stacked in sequence along the Z direction.

[0086] For example, Figure 3 As shown, the track device 110 includes a track frame 115, and the guide rails 111 in this embodiment are arranged in four layers. The guide rails 111a, 111b, 111c, and 111d are sequentially connected to the track frame 115 along the Z direction, and the guide rails 111 of each layer form a first channel 112 and a second channel 113 through the track frame 115. The first channel 112 and the second channel 113 are adjacent to each other along the Y direction in the plane where the guide rails 111 of each layer are located. It can be understood that the first channel 112 and the second channel 113 can be staggered in the Z direction, or can be arranged in parallel, and this embodiment does not make specific requirements for this.

[0087] On one side of the first channel 112 of each layer, which faces away from the second channel 113 in the Y direction, there is a sorting position 114. On one side of the second channel 113 of each layer, which faces away from the first channel 112 in the Y direction, there is also a sorting position 114. It should be noted that the number of sorting positions 114 outside the first channel 112 and the second channel 113 of each layer can be one or more. When the number of sorting positions 114 outside the first channel 112 and the second channel 113 of each layer is multiple, the sorting positions 114 can be arranged at intervals in the X direction in sequence. The distance between adjacent sorting positions 114 can be the same or different, and this embodiment does not make specific requirements for this.

[0088] At least two transfer devices 120 load items and move within the first channel 112 and the second channel 113, thereby driving the items to move to the corresponding sorting positions 114 and delivering the items to the sorting positions 114, realizing the sorting operation of the items.

[0089] Exemplarily, the transfer device 120a is correspondingly arranged with the first channel 112, and the loading device a moves relative to the guide rail 111 in the X direction within the first channel 112. The transfer device 120b is correspondingly arranged with the second channel 113, and the transfer device 120b moves relative to the guide rail 111 in the X direction within the second channel 113. In this way, the transfer device 120a and the transfer device 120b can carry items simultaneously and deliver the items to the sorting positions 114 of the corresponding layer, improving the operation efficiency of the sorting system 100.

[0090] When the transfer device 120 moves to the end of the guide rail 111, under the action of the adjusting device 130, the transfer device 120 moves to the guide rail 111 of other layers.

[0091] It can be understood that in this embodiment, the adjusting device 130a is arranged along the X direction at the end of the track device 110, and the adjusting device 130b is arranged along the X direction at the other end of the track device 110. The adjusting device 130a and the adjusting device 130b are opposite to each other in the X direction.

[0092] The transfer device 120a moves within the first channel 112 corresponding to any layer of the guide rails 111b, 111c, and 111d. When the transfer device 120a moves to the adjusting device 130a, the transfer device 120a can move from the guide rail 111b to the guide rail 111a through the adjusting device 130a; or from the guide rail 111c to the guide rail 111b or 111a; it can also move from the guide rail 111d to the guide rail 111c, 111b, or 111a. That is to say, the transfer device 120a realizes the downward adjustment along the Z direction on each layer of the guide rail 111 through the adjusting device 130a. Or, the transfer device 120a can realize the upward movement along the Z direction on each layer of the guide rail 111 through the adjusting device 130a.

[0093] When the transfer device 120a moves to the adjusting device 130b, the transfer device 120a can move from the guide rail 111a to the guide rail 111b, 111c, or 111d through the adjusting device 130b; or from the guide rail 111b to the guide rail 111c or 111d; it can also move from the guide rail 111c to the guide rail 111d. That is to say, the transfer device 120a realizes the upward adjustment along the Z direction on each layer of the guide rail 111 through the adjusting device 130b. Or, the transfer device 120a can realize the downward adjustment along the Z direction on each layer of the guide rail 111 through the adjusting device 130b.

[0094] It should be noted that the moving directions of the transfer device 120a along the Z direction through the adjusting device 130a and the adjusting device 130b are opposite, which is convenient for the automatic control of the sorting system 100 to improve the operating efficiency of the sorting system 100.

[0095] The transfer device 120b moves within the second channel 113 corresponding to any layer of the guide rails 111b, 111c, and 111d. When the transfer device 120b moves to the adjusting device 130a, the transfer device 120b can move from the guide rail 111a to the guide rail 111b, 111c, or 111d through the adjusting device 130a; or from the guide rail 111b to the guide rail 111c or 111d; it can also move from the guide rail 111c to the guide rail 111d. That is, the transfer device 120b realizes the upward adjustment along the Z direction on each layer of the guide rail 111 through the adjusting device 130a. Or, the transfer device 120b can realize the upward movement along the Z direction on each layer of the guide rail 111 through the adjusting device 130a.

[0096] When the transfer device 120b moves to the adjustment device 130b, the transfer device 120b can be moved from the guide rail 111b to the guide rail 111a through the adjustment device 130b; or from the guide rail 111c to the guide rail 111b or the guide rail 111a; it can also be moved from the guide rail 111d to the guide rail 111c, the guide rail 111b or the guide rail 111a. That is to say, the transfer device 120b realizes the upward adjustment in the Z direction on each layer of the guide rail 111 through the adjustment device 130b. Or, the transfer device 120b can realize the downward adjustment in the Z direction on each layer of the guide rail 111 through the adjustment device b.

[0097] It should be noted that the moving directions of the transfer device 120a along the Z direction through the adjustment device 130a and the adjustment device 130b are opposite, which is convenient for the automatic control of the sorting system 100 to improve the operation efficiency of the sorting system 100.

[0098] It is not difficult to understand that the adjustment device 130a can drive the transfer device 120a and the transfer device 120b to rise or fall at the same time. Correspondingly, the adjustment device 130b can drive the transfer device 120a and the transfer device 120b to fall or rise at the same time. Or, the adjustment device 130a drives the transfer device 120a to rise or fall, and at the same time drives the transfer device 120b to fall or rise. Correspondingly, the adjustment device 130a drives the transfer device 120a to fall or rise, and at the same time drives the transfer device 120b to rise or fall. In this way, through different motion control methods of the adjustment device 130, the transfer device 120 can move quickly on each layer of the guide rail 111, thereby improving the operation efficiency of the sorting system 100.

[0099] It should be noted that the transfer device 120 in this embodiment can be a movable trolley or a mobile robot, etc., and the embodiments of the present application do not make specific requirements in this regard. In addition, during the movement of the transfer device 120, it can be in an empty state or in a state of loading items.

[0100] In some embodiments, the transfer device 120 includes a base 121, a conveyor belt 122, a communication component 123, traveling wheels 124, and limiting wheels 125. The conveyor belt 122 is disposed on the base 121, and the conveyor belt 122 makes a rotary motion relative to the base 121. The traveling wheels 124 and the limiting wheels 125 are connected to the bottom of the base 121. When the transfer device 120 moves on the guide rail 111, the traveling wheels 124 and the guide rail 111 are in contact along the Z direction, the traveling wheels 124 rotate, and the transfer device 120 moves on the guide rail 111. During the movement of the transfer device 120, the limiting wheels 125 and the guide rail 111 are in contact along the Y direction to prevent the transfer device 120 from derailing, ensure the stable movement of the transfer device 120 in each layer of the guide rail 111 along the X direction, and ensure the safety and stability of the sorting system 100, and improve the sorting operation efficiency of the sorting system 100.

[0101] The communication component 123 is disposed on the base 121. The communication component 123 is used for receiving and transmitting wireless signals. Through the communication component 123, various working conditions of the operation of the transfer device 120 can be obtained. At the same time, the transfer device 120 can also work according to the wireless instructions obtained by the communication component 123.

[0102] In a possible embodiment, the moving directions of the transfer device 120 in the first channel 112 and the second channel 113 are opposite. That is to say, the transfer device 120a can move from one side of the adjusting device 130a to the other side of the adjusting device 130b in the first channel 112, or can move from one side of the adjusting device 130b to the other side of the adjusting device 130a; correspondingly, the transfer device 120b can move from one side of the adjusting device 130b to the other side of the adjusting device 130a in the first channel 112, or can move from one side of the adjusting device 130a to the other side of the adjusting device 130b.

[0103] In this way, through the optimized design of the moving paths of the transfer device 120 in the corresponding first channel 112 and second channel 113, it is beneficial to the flexible design of the sorting system 100, thereby improving the sorting operation efficiency of the sorting system 100 for items.

[0104] Possibly, the adjusting device 130 has a third channel 132 and a fourth channel 133. Both the third channel 132 and the fourth channel 133 extend along the first direction (Z direction). The end of the first channel 112 along the second direction (X direction) communicates with the third channel 132, and the end of the second channel 113 along the second direction communicates with the fourth channel 133; the first direction (Z direction) intersects with the second direction (X direction). Connection components 134 are provided in both the third channel 132 and the fourth channel 133. The connection components 134 drive the transfer device 120 to move to the guide rails 111 on other layers. In this way, through the independent channel design of the adjusting device 130, the independent movement of the transfer device 120 in different channels is realized, so as to ensure the reliable operation of the sorting system 100 and further improve the sorting operation efficiency of the sorting system 100.

[0105] Combined Figures 1 - 7 , in this embodiment, the guide rail 111 extends along the second direction (X direction), and the second direction can be the X direction marked in the figure. Adjusting devices 130a and 130b are respectively provided at both ends of the guide rail 111 along the X direction. The adjusting devices 130a and 130b include a housing 131, and the housing 131 has a third channel 132 and a fourth channel 133. The third channel 132 and the fourth channel 133 are arranged adjacent to each other. Among them, the third channel 132 extends along the Z direction, and the third channel 132 and the first channel 112 are correspondingly arranged. It can be understood that the end of each first channel 112 along the X direction facing the adjusting device 130a communicates with the third channel 132 of the adjusting device 130a, and the end of each first channel 112 along the X direction facing the adjusting device 130b communicates with the third channel 132 of the adjusting device 130b.

[0106] The end of each second channel 113 along the X direction facing the adjusting device 130a communicates with the fourth channel 133 of the adjusting device 130a, and the end of each second channel 113 along the X direction facing the adjusting device 130b communicates with the fourth channel 133 of the adjusting device 130b.

[0107] When the transfer device 120 moves to the end of the guide rail 111, the transfer device 120a is located at the communication point of the first channel 112 and the third channel 132, and the transfer device 120b is located at the communication point of the second channel 113 and the fourth channel 133. The transfer devices 120a and 120b are moved along the Z direction through the adjusting device 130, that is to say, the adjusting device 130 drives the transfer device 120 to move to other guide rails 111 of the track device 110. At this time, during the movement of the transfer devices 120 in the first channel 112 and the second channel 113, the loaded items are delivered to the sorting position 114. Of course, the transfer devices 120 in the first channel 112 and the second channel 113 can also move empty.

[0108] Specifically, the transfer device 120 moves along the Z direction through the connection component 134. The connection component 134 is located in the third channel 132 and the fourth channel 133 and moves along the Z direction in the third channel 132 and the fourth channel 133. As Figures 5 - 7 shown, the movement of the connection component 134 in the third channel 132 and the fourth channel 133 rotates along the Z direction.

[0109] The connection component 134 includes a connection plate 1341. The connection plate 1341 moves along the Z direction. The transfer device 120 moves into the corresponding third channel 132 and fourth channel 133. The transfer device 120 and the connection plate 1341 are in contact with each other along the Z direction. In this way, the connection plate 1341 rises or falls along the Z direction to drive the transfer device 120 to move along the Z direction to each layer of guide rails 111.

[0110] Figure 8 It is a schematic diagram of the connection component in the sorting system provided by the embodiment of the present application.

[0111] As Figure 8 shown, the connection plate 1341 has a connection surface 1342 and a limiting surface 1343. The traveling wheels 124 of the transfer device 120 move on the connection surface 1342, and the transfer device 120 enters the corresponding third channel 132 and fourth channel 133. The limiting wheels 125 of the transfer device 120 are in contact with and move relative to the limiting surface 1343. The setting of the limiting surface 1343 can keep the transfer device 120 and the connection plate 1341 stable during the common movement, and at the same time prevent the transfer device 120 from disconnecting from the connection plate 1341 when entering the third channel 132 or the fourth channel 133. A guiding surface 1344 can be provided at the end of the limiting surface 1343 of the connection plate 1341 along the X direction. There is an included angle between the guiding surface 1344 and the limiting surface 1343. The guiding surface 1344 forms a horn-shaped structure, which is beneficial to the transfer device 120 moving onto the connection plate 1341, and the movement of the transfer device 120 is smoother.

[0112] It should be noted that the guiding surface 1344 in this embodiment can be provided at one end of the limiting surface 1343 along the X direction, and this end can be close to the side of the guide rail 111 so that the transfer device 120 can move onto the connection plate 1341. Of course, guiding surfaces 1344 can be provided at both ends of the limiting surface 1343 along the X direction, which can reduce the mold opening cost of the transfer device 120.

[0113] The connection plate 1341 is also provided with a stopper 1345, which is arranged along the X direction on the side of the connection plate 1341 away from the transfer device 120, and is connected to the connection surface 1342 of the connection plate 1341 along the Y direction. The transfer device 120 moves along the X direction on the connection plate 1341, and the stopper 1345 stops and limits the transfer device 120, preventing the transfer device 120 from excessively moving on the connection plate 1341, thereby ensuring the stability and safety of the sorting system 100.

[0114] Possibly, the adjustment device 130 includes a connecting frame 135 and three slide rail assemblies 136, the three slide rail assemblies 136 are arranged at intervals on the connecting frame 135, and form a third channel 132 and a fourth channel 133, the connecting assembly 134 is rotatable and slidably connected relative to the slide rail assemblies 136; on adjacent slide rail assemblies 136, the connecting assembly 134 is aligned in the third channel 132 and the fourth channel 133 along the first direction (Z direction). Through the connection between the connecting assembly 134 and the slide rail assembly 136, the transfer device 120 is moved along the Z direction, and the transfer device 120 can move to different guide rails 111 of the track device 110 to complete the sorting and delivery operation of the items. The connection components 134 in the same channel are aligned to ensure stable movement of the transfer device 120 relative to the connection components 134 along the X direction, and to prevent the transfer device 120 from falling from the adjustment device 130 due to the tilt of the connection components 134, thereby ensuring reliable and safe operation of the sorting system 100 and further improving the sorting operation efficiency of the sorting system 100.

[0115] In this embodiment, the slide rail assembly 136a, the slide rail assembly 136b and the slide rail assembly 136c are arranged in sequence along the Y direction and connected to the connecting frame 135. The slide rail assembly 136a and the slide rail assembly 136b form the third channel 132, and the slide rail assembly 136b and the slide rail assembly 136c form the fourth channel 133. The connecting assembly 134 is respectively connected to the slide rail assembly 136a, the slide rail assembly 136b and the slide rail assembly 136c, and the connecting assembly 134 slides relative to the slide rail assembly 136 along the Z direction.

[0116] In some embodiments, the sliding path of the connecting assembly 134 relative to the slide rail assembly 136 is a rotation path.

[0117] Specifically, each slide rail assembly 136 includes a first slide rail 1361 and a second slide rail 1362, and the first slide rail 1361 and the second slide rail 1362 are arranged on the connecting frame 135. The first slide rail 1361 is an annular track, and the connecting assembly 134 is connected to the first slide rail 1361 and slides through the first slide rail 1361. A first guide wheel 1346 corresponding to the first slide rail 1361 is arranged on the side of the connecting plate 1341 away from the connecting surface 1342 along the Y direction, and the first guide wheel 1346 is located in the first slide rail 1361 and slides relative to the first slide rail 1361. The arrangement of the first guide wheel 1346 can reduce the friction between the connecting assembly 134 and the slide rail assembly 136, improve the movement smoothness and stability between the connecting assembly 134 and the slide rail assembly 136, and can also reduce the energy consumption of the sorting system 100.

[0118] The second slide rail 1362 extends in the Z direction, and a second guide wheel 1347 corresponding to the second slide rail 1362 is provided on the side of the connecting plate 1341 away from the connecting surface 1342 in the Y direction, and the second guide wheel 1347 is located in the second slide rail 1362. In this embodiment, the movement of the connecting assembly 134 in the X direction is limited by the cooperation between the second guide wheel 1347 and the second slide rail 1362, and the tilting rotation of the connecting assembly 134 around the X axis is limited, so as to ensure that the connection between the transfer device 120 and the connecting assembly 134 is stable during the movement of the connecting assembly 134, thereby improving the stability and safety of the sorting system 100 and the sorting operation efficiency of the sorting system 100.

[0119] Figure 9 This is an isometric view of a partial structure of an adjustment device in a sorting system provided in an embodiment of the present application. Figure 10 for Figure 9 A partial enlarged view of the dotted box part.

[0120] In addition, combined Figure 5 , Figure 6 , Figure 9 , Figure 10, the connecting plates 1341 on both sides of the third channel 132 along the Y direction are flush with each other in the Z direction, and the connecting plates 1341 on both sides of the fourth channel 133 along the Y direction are flush with each other in the Z direction. It can be understood that the connecting plates 1341 on the slide rail assembly 136a and the connecting plates 1341 on the slide rail assembly 136b need to drive the transfer device 120 to move along the Z direction simultaneously in the third channel 132, and the connecting plates 1341 on the slide rail assembly 136b and the connecting plates 1341 on the slide rail assembly 136c need to drive the transfer device 120 to move along the Z direction simultaneously. Among them, the connecting surface 1342 of each connecting plate 1341 abuts against the transfer device 120 along the Z direction. Therefore, the connecting plates 1341 in the same channel are flush with each other in the Z direction, which can prevent the transfer device 120 from tilting, so that the transfer device 120 can move smoothly along the Z direction through the adjusting device 130.

[0121] Possibly, the adjusting device 130 further includes a driving component 137. The driving components 137 are provided in one-to-one correspondence with the slide rail assemblies 136. The driving component 137 is connected to the connecting component 134, and the driving component 137 is configured to drive the connecting component 134 to move so as to drive the transfer device 120 to move.

[0122] Combined Figures 5 - 9 As shown, the driving components 137 are provided in one-to-one correspondence with the slide rail assemblies 136 and are connected to the connecting component 134. That is to say, there are three driving components 137 in this embodiment, which are respectively connected to the connecting components 134 on the corresponding slide rail assemblies 136, so as to drive the connecting component 134 to drive the transfer device 120 to move along the Z direction.

[0123] Exemplarily, each driving component 137 includes a motor 1371, a transmission shaft 1372, a transmission wheel 1373 and a transmission belt 1374. The motor 1371 is arranged on the cross beam 1351 of the connecting frame 135 along the Z direction. The motor 1371, the transmission shaft 1372 and the transmission wheel 1373 are arranged in sequence along the X direction. The output shaft of the motor 1371 and the transmission shaft 1372 can be connected through a coupling (not shown in the figure). The transmission wheel 1373 is connected to the transmission shaft 1372. The transmission belt 1374 is sleeved on the transmission wheel 1373 and rotates under the drive of the motor 1371. The connecting plate 1341 is connected to the transmission belt 1374, and through the mutual cooperation of the driving component 137, the movement along the Z direction is realized.

[0124] In some embodiments, the driving component 137 further includes a reducer 1375. The reducer 1375 is connected between the output shaft of the motor 1371 and the transmission shaft 1372 to reduce the torque of the motor 1371.

[0125] It can be understood that the connecting components 134 in the third channel 132 move in the same direction under the drive of the drive component 137, and the connecting components 134 in the fourth channel 133 move in the same direction under the drive of the drive component 137. Thus, with such a structural arrangement in this embodiment, the transfer device 120a can be lifted / descended in the Z direction, while the transfer device 120b descends / ascends in the Z direction, reducing the space occupation ratio of the adjustment device 130, lowering the cost of the sorting system 100, and simplifying the design of the automatic control of the sorting system 100.

[0126] In some embodiments, in at least one layer of the guide rail 111, the same end of the extending directions of the first channel 112 and the second channel 113 are interconnected; when the transfer device 120 is located at the interconnected position of the first channel 112 and the second channel 113, the article is transferred between the first channel 112 and the second channel 113. Thus, no matter which transfer device 120 the article is loaded on in the first channel 112 and the second channel 113, the article can be delivered to the sorting position 114 of the first channel 112 or the second channel 113, improving the operation efficiency of article sorting.

[0127] Combined with Figure 2 and Figure 3 , in the bottom layer of the guide rail 111, both ends of the first channel 112 and the second channel 113 along the X direction are interconnected. At this time, the transfer device 120a in the first channel 112 loads the article and moves to the end close to the adjustment device 130b, and there is an empty transfer device 120b staying at the end close to the adjustment device 130b in the adjacent second channel 113. The article loaded on the transfer device 120a is transferred to the transfer device 120b in the second channel 113 at the interconnected position of the first channel 112 and the second channel 113. The transfer device 120b moves along the X direction towards the adjustment device 130a. During the movement, the transfer device 120b can deliver the article to the sorting position 114 of the second channel 113 in the bottom layer. The transfer device 120b that has completed the transfer of the article for sorting can continue to load the article or move to the adjustment device 130a in an empty state, rise to other layers through the adjustment device 130a, move to the adjustment device 130b, and descend to other layers or the bottom layer through the adjustment device 130b.

[0128] When the transfer device 120b loads the article and moves to the guide rail 111 of other layers through the adjustment device 130a, the transfer device 120b can deliver the article to the sorting position 114 of the second channel 113 corresponding to the guide rail 111 of other layers.

[0129] Correspondingly, the transfer device 120b in the second channel 113 loads the articles and moves to the end close to the adjustment device 130a. An empty transfer device 120a stays at the end close to the adjustment device 130a in the adjacent first channel 112. The articles loaded on the transfer device 120b are transferred to the transfer device 120a in the first channel 112 at the connection between the second channel 113 and the first channel 112. The transfer device 120a moves along the X direction towards the adjustment device 130b. During the movement, the transfer device 120a can deliver the articles to the sorting position 114 of the first channel 112 at the bottom layer. The transfer device 120a that has completed the sorting and delivery of the articles can continue to load the articles or move to the adjustment device 130b in an empty state, rise to other layers through the adjustment device 130b, move to the adjustment device 130a, and descend to other layers or the bottom layer through the adjustment device 130a.

[0130] When the transfer device 120a loads the articles and moves to the guide rail 111 on other layers through the adjustment device 130b, the transfer device 120a can deliver the articles to the sorting position 114 of the first channel 112 corresponding to the guide rail 111 on other layers.

[0131] It should be noted that when the articles are transferred between the first channel 112 and the second channel 113, the movement of the articles can be driven by the rotation of the conveyor belt 122 of the transfer device 120. In addition, the above part describes the implementation mode in which the corresponding first channel 112 and the second channel 113 at both ends along the X direction are connected in the guide rail 111 at the bottom layer. Of course, the articles can also be transferred at the connection between the first channel 112 and the second channel 113 when one end of the corresponding first channel 112 and the second channel 113 along the X direction is connected.

[0132] In addition, the ends of the corresponding first channel 112 and the second channel 113 on any layer of the guide rail 111 can be connected to each other, so that the transfer device 120 loaded with articles can move between the first channel 112 and the second channel 113 on any layer. Of course, the ends of the corresponding first channel 112 and the second channel 113 on each layer of the guide rail 111 can be connected to each other. This part does not limit which specific layer of the guide rail 111 the first channel 112 and the second channel 113 are connected.

[0133] Exemplarily, the rail device 110 includes a connecting member 116. The same ends of the first channel 112 and the second channel 113 are communicated through the connecting member 116; articles are transferred between the first channel 112 and the second channel 113 through the connecting member 116. In this way, the articles are transferred between the first channel 112 and the second channel 113 through the connecting member 116, which can prevent the articles from falling during the transfer process, improve the stability of the mutual transfer of the articles in the first channel 112 and the second channel 113, further prevent the articles from falling or getting stuck in a certain position, resulting in the stopping of the sorting system 100, thereby ensuring the sustainability of the sorting operation of the sorting system 100 for the articles and improving the sorting operation efficiency.

[0134] In this embodiment, the connecting member 116 can be arranged in the Z direction at the communication position between the corresponding first channel 112 and the second channel 113 of the bottom guide rail 111, and the connecting member 116 is relatively stably connected. The top surface of the connecting member 116 in the Z direction is substantially flush with the plane where the conveyor belts 122 of the transfer device 120a and the transfer device 120b are located, so that articles can be transferred between the first channel 112 and the second channel 113. Of course, according to the communication situation of the first channel 112 and the second channel 113 on different layers of the guide rail 111, the connecting member 116 can be correspondingly arranged at the communication position between the first channel 112 and the second channel 113.

[0135] It should be noted that the connecting member 116 can be a plate member. As the conveyor belt 122 of the transfer device 120 rotates, the articles move through the connecting member 116 under the action of inertia. The connecting member 116 can also be a conveyor belt. The conveyor belt can move under the action of a driving roller. As the conveyor belt 122 of the transfer device 120 rotates, the articles move onto the conveyor belt, and the conveyor belt rotates to drive the articles to be transferred at the communication position between the first channel 112 and the second channel 113.

[0136] Possibly, referring to Figures 1 - 3 , the sorting system 100 further includes a storage member 140, and the storage member 140 is arranged in one-to-one correspondence with the sorting position 114; the storage member 140 is configured to receive the articles delivered to the sorting position 114. In this way, it is convenient for the subsequent operation of the articles after being sorted by the sorting system 100.

[0137] Figure 11 It is a top view of the connection state between the transfer device and the adjustment device in the sorting system provided by the embodiment of the present application. Figure 12 It is Figure 11 The partial enlarged view of the dashed box part in Figure 13 It is the axonometric Figure 2 . Figure 14 It is Figure 13 The partial enlarged view of part Ⅰ in Figure 15 It isFigure 13 Partial enlarged view of part II.

[0138] In some embodiments, the sorting system 100 further includes a detection component, which is respectively arranged on the rail device 110, the transfer device 120, and the adjustment device 130; the detection component is configured to respectively detect the relative positions of at least one of the connections between the transfer device 120 and the adjustment device 130, and between the adjustment device 130 and the rail device 110; the controller 160 is electrically connected to the detection component, the transfer device 120, the rail device 110, and the adjustment device 130. In this embodiment, by arranging the detection component to detect the relative positions between the components of the sorting system 100, the stability and reliability of the operation between the components during the operation of the sorting system 100 are ensured, thereby improving the operation efficiency of the sorting system 100 for sorting items.

[0139] Specifically, the detection component includes a first detector 150, which is arranged on the transfer device 120, and the detection end of the first detector 150 faces the connection component 134; the first detector 150 is configured to detect the relative position between the transfer device 120 and the connection component 134, and the controller 160 responds to the detection signal of the first detector 150 to control the transfer device 120 to stop at the connection component 134; and / or, the detection component further includes a second detector 151, which is arranged on the connecting frame 135, and the second detector 151 is respectively arranged corresponding to the first channel 112 and the second channel 113, and the detection end of the second detector 151 faces the transfer device 120; the second detector 151 is configured to detect the relative position between the transfer device 120 and the connecting frame 135, and the controller 160 responds to the detection signal of the second detector 151 to control the connection component 134 to drive the transfer device 120 to move. The controller 160 performs in-position detection on the movement of the transfer device 120 into the adjustment device 130 through the detection signals of the first detector 150 and / or the second detector 151, so as to improve the movement stability and safety of the sorting system 100, and further improve the operation efficiency of the sorting system 100.

[0140] Combined with Figure 1 、 Figure 2 、 Figure 13 、 Figure 15, the detection component includes a first detector 150. The first detector is disposed on the transfer device 120. A first detection member 1349 corresponding to the first detector 150 is disposed on the connection plate 1341. The detection end of the first detector 150 faces the connection plate 1341. The transfer device 120 moves onto the connection plate 1341 and enters the third channel 132 and the fourth channel 133 of the corresponding adjustment device 130 along the X direction. A detection signal is formed between the first detector 150 on the transfer device 120 and the first detection member 1349, and the detection signal can reflect the relative position between the transfer device 120 and the adjustment device 130.

[0141] It can be understood that the detection signal formed between the first detector 150 and the first detection member 1349 is fed back to the controller 160. The controller 160 determines based on this detection signal that the transfer device 120 has been relatively stably connected to the connection plate 1341, that is, the transfer device 120 has moved into place relative to the connection plate 1341. At this time, the controller 160 can send out a wireless command signal. The communication component 123 of the transfer device 120 receives this command, the transfer device 120 stops, and parks on the corresponding connection plate 1341, and at the same time waits for the adjustment device 130 to start.

[0142] Combined with Figure 1 , Figure 2 , Figure 13 , Figure 14 , the detection component further includes a second detector 151. The second detector 151 is electrically connected to the controller 160. The second detector 151 is disposed on the connection frame 135 of the adjustment device 130 and is located at the connection of the first channel 112 and the third channel 132 and at the connection of the second channel 113 and the fourth channel 133. And the detection end of the second detector 151 faces the transfer device 120 along the X direction. Second detection members 126 are disposed on both sides of the transfer device 120 along the X direction. When the transfer device 120 is located at the connection of the third channel 132 and the corresponding first channel 112, and at the connection of the fourth channel 133 and the corresponding second channel 113, a detection signal is formed between the second detection member 126 of the transfer device 120 and the second detector 151 to reflect the relative position between the transfer device 120 and the adjustment device 130. It can be understood that the second detector 151 feeds back this detection signal to the controller 160, and the controller 160 can determine that the transfer device 120 has entered the corresponding third channel 132 and fourth channel 133 and has been in place relative to the connection plate 1341, so as to control the connection component 134 to drive the transfer device 120 to move along the Z direction.

[0143] In this way, the controller 160 jointly determines the positioning of the transfer device 120 in the third channel 132 and the fourth channel 133 based on the detection signals respectively sent by the first detector 150 and the second detector 151, thereby ensuring the stability and reliability of the sorting system 100 and further improving the sorting operation efficiency of the sorting system 100.

[0144] In some embodiments, the detection assembly includes a third detector 152. The third detector 152 is disposed on the connecting frame 135 and is correspondingly disposed with the driving assembly 137 respectively. The detection end of the third detector 152 faces the connecting assembly 134. The third detector 152 is configured to detect the relative position between the connecting assembly 134 and the connecting frame 135. The controller 160 controls the connecting assembly 134 to stop in response to the detection signal of the third detector 152, so that the transfer device 120 moves between the guide rail 111 and the connecting assembly 134. In this way, through the coordinated control of the third detector 152 and the controller 160, the connecting assembly 134 is docked to receive the transfer device 120, and the connecting assembly 134 is docked layer by layer relative to the guide rail 111, ensuring the smooth movement of the transfer device 120 between the guide rail 111 and the connecting assembly 134, and further ensuring the movement consistency and stability of the connecting assemblies 134 in the third channel 132 and the fourth channel 133.

[0145] Combined Figure 5 、 Figure 6 、 Figure 11 、 Figure 13 、 Figure 14, the third detector 152 and the controller 160 are electrically connected, and the adjusting device 130 and the controller 160 are electrically connected. The third detector 152 is disposed on the connecting frame 135 of the adjusting device 130, and the third detector 152 is located at the communication of the first channel 112 and the third channel 132 and the communication of the second channel 113 and the fourth channel 133. Correspondingly, a third detecting member 1348 corresponding to the third detector 152 is disposed on the connecting plate 1341. The connecting plate 1341 moves along the Z direction under the driving action of the driving assembly 137. When the connecting plate 1341 reaches the ends of the corresponding first channel 112 and the second channel 113 along the Z direction, a detection signal is formed between the third detector 152 and the third detecting member 1348 on the connecting plate 1341, and the detection signal is fed back to the controller 160. The controller 160 can then determine that the connecting plate 1341 has reached the ends of the corresponding first channel 112 and the second channel 113, and then control the adjusting device 130 to temporarily stop, so that the transfer device 120 on each layer of the guide rail 111 enters the third channel 132 and the fourth channel 133; or the transfer device 120 on each layer of the guide rail 111 leaves from the third channel 132 and the fourth channel 133 and enters the corresponding first channel 112 and the second channel 113 of each layer of the guide rail 111 to complete the sorting and delivery of the articles.

[0146] It is not difficult to understand that the driving assembly 137 and the slide rail assembly 136 are correspondingly arranged, and each driving assembly 137 drives the connecting component 134 on the corresponding slide rail assembly 136 to move along the Z direction. Thus, through the setting of the third detector 152, it can be ensured that the connecting components 134 on each slide rail assembly 136 move in the same position along the Z direction under the driving of the driving assembly 137, thereby ensuring the stability of the transfer device 120 moving along the Z direction through the connecting component 134, so as to make the transfer device 120 move smoothly between the connecting component 134 and the guide rail 111.

[0147] Possibly, the detection assembly includes a fourth detector 153. The fourth detector 153 is correspondingly disposed on at least one side of the third channel 132 and the fourth channel 133 along the first direction (Z direction); the detection ends of the fourth detector 153 respectively face the transfer device 120 in the third channel 132 and the fourth channel 133; the fourth detector 153 is configured to detect the relative position between the transfer device 120 and the connecting frame 135; the controller 160 responds to the detection signal of the fourth detector 153 to control the connecting component 134 to stop rotating and issue a prompt signal. By arranging the fourth detector 153 along the Z direction of the third channel 132 and the fourth channel 133, it can be timely prompted when the driving assembly 137 drives the connecting component 134 to fail and drives the transfer device 120 to move in the reverse direction. Thus, the staff can take emergency stop measures for the adjusting device 130 in time to prevent structural damage to the sorting system 100.

[0148] Combined with Figure 1 、 Figure 2 、 Figures 11 - 14 Figures 11 - 14 There may be two fourth detectors 153, and the two fourth detectors 153 are sequentially arranged at intervals along the Z direction on the opposite sides of the corresponding third channel 132 and fourth channel 133. When the fourth detector 153 faces the transfer device 120. When the transfer device 120 moves along the Z direction in the corresponding third channel 132 and fourth channel 133, there may be an abnormal control of the drive assembly 137 in the adjustment device 130, resulting in the drive assembly 137 driving the connection assembly 134 to reverse. When a detection signal is formed between the fourth detector 153 and the second detection member 126 of the transfer device 120, the controller 160 controls the connection assembly 134 to stop rotating in a timely manner according to the detection signal of the fourth detector 153, and issues a prompt signal so that the staff can make a timely response, thereby ensuring the stability and reliability of the operation of the sorting system 100.

[0149] It should be noted that the first detector 150, the second detector 151, the third detector 152, and the fourth detector 153 in this embodiment may be photoelectric sensors, pressure sensors, travel switches, etc., and the detection signals formed by the corresponding first detector 150, second detector 151, third detector 152, and fourth detector 153 may be corresponding photoelectric signals, pressure signals, and electrical signals, etc.

[0150] Optionally, the sorting system 100 further includes a first conveyor line, and the first conveyor line is respectively arranged at the ends of the first channel 112 and / or the second channel 113. Through the arrangement of the first conveyor line in this embodiment, the automation degree of the sorting system 100 and the sorting operation efficiency of the sorting system 100 can be improved.

[0151] It is not difficult to understand that the first conveyor line can be arranged at the end of the first channel 112, and the transfer device 120 moving into the first channel 112 is conveyed through the first conveyor line. The first conveyor line can also be arranged at the end of the second channel 113, and the transfer device 120 moving into the second channel 113 is conveyed through the first conveyor line.

[0152] Of course, the first conveyor line can be respectively arranged at the ends of the first channel 112 and the second channel 113 at the same time. The ends on the same side can also be the ends on different sides. In this way, the transfer device 120 in the first channel 112 and the second channel 113 can be conveyed with items at the same time to improve the sorting efficiency of the items.

[0153] It should be noted that the first conveyor line can be provided corresponding to the first channels 112 and / or the second channels 113 of each layer, or only provided for the first channels 112 and / or the second channels 113 of a certain layer among them. This part has no requirements in this regard.

[0154] See Figure 1 and Figure 2 , the sorting system 100 further includes a second conveyor line 170. Along the moving direction of the transfer device 120 in the first channel 112 and the second channel 113, the second conveyor line 170 is provided at the ends of the first channel 112 and the second channel 113. In this way, the no-load probability of the transfer device 120 moving to the second conveyor line 170 in the first channel and the second channel 113 can be increased, thereby improving the operation efficiency of the sorting system 100 and realizing efficient sorting of items.

[0155] It is not difficult to understand that the transfer device 120 can move along the X direction in the first channel 112 from the adjusting device 130a to the adjusting device 130b. The transfer device 120 can load items and move in the first channel 112 to the adjusting device 130b. Through the adjusting device 130b, it moves to other layers of the guide rail 111 to complete the sorting and delivery of items.

[0156] Or, when the transfer device 120 loads items and moves in the first channel 112 and moves to the connection between the first channel 112 and the second channel 113, the items are transferred to the transfer device 120 in the second channel 113, and during the process of the transfer device 120 in the second channel 113 moving along the X direction from the adjusting device 130b to the adjusting device 130a, the sorting and delivery of items are completed.

[0157] Correspondingly, the moving directions of the transfer device 120 in the second channel 113 and the transfer device 120 in the first channel 112 are opposite, and the working principle and working process are the same, so this part will not be elaborated here.

[0158] In this way, when the moving directions of the transfer device 120 in the first channel 112 and the second channel 113 are opposite, the second conveyor line 170 is arranged along the moving direction of the transfer device 120, which can increase the no-load probability of the transfer device 120 at the connection between the first channel 112 and the second channel 113, reduce the waiting time for the transfer of items at the connection between the first channel 112 and the second channel 113, and thus improve the operation efficiency of the sorting system 100.

[0159] It should be noted that the number of the first conveyor line and the second conveyor line 170 corresponding to the first channel 112 and the second channel 113 in this application can be one or multiple, and the specific number is not required in this embodiment.

[0160] In some embodiments, such asFigure 2 As shown in Figure Figure 2 , the sorting system 100 further includes a power supply device 180, which is located in the first channel 112 and the second channel 113 at the bottom layer, and extends along the extension direction of the guide rail 111. The power supply device 180 is configured to supply power to the transfer device 120 in the corresponding first channel 112 and second channel 113. In this way, the transfer device 120 can be charged each time it moves in the guide rail 111 at the bottom layer, realizing the on-line charging of the transfer device 120 during the sorting operation, saving the charging time of the transfer device 120, and improving the sorting operation efficiency of the sorting system 100.

[0161] The sorting system 100 provided by the embodiment of the present application includes: a track device 110, an adjusting device 130, and at least two transfer devices 120. Among them, the track device 110 includes at least two layers of stacked guide rails 111. The guide rail 111 has adjacent first channels 112 and second channels 113. On the sides of the first channel 112 and the second channel 113 facing away from each other, there are sorting positions 114. At least two transfer devices 120 are movably located in the first channel 112 and the second channel 113; the transfer device 120 is configured to load items and deliver the items to the sorting position 114. The adjusting device 130 is respectively connected to both ends of the track device 110. When the transfer device 120 moves to the end of the guide rail 111, the transfer device 120 moves to the guide rail 111 of other layers through the adjusting device 130. Through such a setting, the sorting operation efficiency of the sorting system 100 for items is improved.
