[0037] The embodiments of the present application provide a conveying device, a sorting system and a control method of the sorting system. The following are described in detail respectively.

[0038] Firstly, the embodiments of the present application provide a conveying device.

[0039] Figure 1 The structure of an embodiment of the conveying device provided by the embodiments of the present application is shown. As shown in the figure, Figure 1 The conveying device 100 is mainly used in the logistics transfer site. The conveying device 100 includes a first conveying structure 110, an unloading area 140 and a sorting area 150. The input end of the first conveying structure 110 is connected with the unloading area 140, and the output end of the first conveying structure 110 is connected with the sorting area 150. When the truck or other cargo transport tool enters the logistics transfer site, it will move to the unloading area 140 of the conveying device 100 for unloading. The unloaded cargo is conveyed to the sorting area 150 or other areas of the conveying device 100 by the first conveying structure 110.

[0040] The conveying device 100 further includes a passageway 160 between the unloading area 140 and the sorting area 150. The passageway 160 is used for the walking of workers or transport tools such as forklifts and ground bulls. Since the passageway 160 is located between the unloading area 140 and the sorting area 150 of the conveying device 100, the first conveying structure 110 of the conveying device 100 is partially located above the passageway 160 and intersects with the passageway 160, which blocks the passageway 160 and prevents personnel or transport tools from passing through the passageway 160, resulting in inconvenience in using the conveying device 100.

[0041] In order to avoid the above problems, the first conveying structure 110 of the conveying device 100 in the embodiments of the present application includes an unloading conveying assembly 111 and a telescopic conveying assembly 113. The input end of the unloading conveying assembly 111 is connected with the unloading area 140. When the truck or other cargo transport tool moves to the unloading area 140 of the conveying device 100 for unloading, the unloaded cargo is manually or by a carrying tool carried to the unloading conveying assembly 111, and the cargo is conveyed out by the unloading conveying assembly 111.

[0042] It should be noted that the input end of the unloading transfer component 111 is connected to the unloading area 140. This can be because the input end of the unloading transfer component 111 is located in the unloading area 140, or the input end of the unloading transfer component 111 is extended to the unloading area 140 through other transfer structures 1111. The only requirement is that the goods in the unloading area 140 can be moved to the input end of the unloading transfer component 111 and then transferred out by the unloading transfer component 111.

[0043] For example, the first conveying structure 110 further includes a second conveying component 112. The output end of the second conveying component 112 is connected to the input end of the unloading conveying component 111. The input end of the second conveying component 112 is located in the unloading area 140, so that the input end of the unloading conveying component 111 is connected to the unloading area 140. The second conveying component 112 can be a belt conveying structure 1111, a roller conveying structure 1111, etc., and is not limited here.

[0044] The telescopic transmission assembly 113 has an extended position and a retracted position. The telescopic transmission assembly 113 is a transmission assembly with a variable length, which can be a transmission belt structure, a transmission roller structure, a transmission chain structure, etc., as long as the length of the telescopic transmission assembly 113 can be changed, there is no limitation here.

[0045] Among them, the telescopic transmission component 113 is in the extended position (e.g. Figure 1 As shown in the structure of the telescopic conveyor assembly 113 on the left side, the telescopic conveyor assembly 113 is located above the channel 160. The input end of the telescopic conveyor assembly 113 is connected to the output end of the unloading conveyor assembly 111, and the output end of the telescopic conveyor assembly 113 is connected to the sorting area 150. Thus, when goods are moved from the unloading area 140 onto the unloading conveyor assembly 111, the unloading conveyor assembly 111 can transfer the goods on it from its output end to the telescopic conveyor assembly 113, and then through the telescopic conveyor assembly 113 to the sorting area 150, so that operators can sort the goods.

[0046] It should be noted that the telescopic transmission component 113 is in the extended position (e.g., Figure 1 When the structure of the telescopic transfer component 113 on the left is shown, the input end of the telescopic transfer component 113 is connected to the output end of the unloading transfer component 111. Alternatively, the input end of the telescopic transfer component 113 can be connected to the output end of the unloading transfer component 111, or the input end of the telescopic transfer component 113 can be kept at a certain distance from the output end of the unloading transfer component 111. The only requirement is that the goods on the unloading transfer component 111 can be transferred from its output end to the telescopic transfer component 113.

[0047] In addition, when the telescopic conveying assembly 113 is in the extended position, the output end of the telescopic conveying assembly 113 is in abutment with the sorting area 150, which can be that the output end of the telescopic conveying assembly 113 is located in the sorting area 150, or the output end of the telescopic conveying assembly 113 is extended to the sorting area 150 through other conveying structures 1111, as long as the goods on the telescopic conveying assembly 113 can be conveyed from the output end thereof to the unloading area 140.

[0048] For example, the first conveying structure 110 further comprises a third conveying assembly 114, the third conveying assembly 114 is located on the opposite sides of the passageway 160 with the unloading conveying assembly 111, the output end of the third conveying assembly 114 is located in the sorting area 150, and the output end of the telescopic conveying assembly 113 is in abutment with the input end of the third conveying assembly 114, so that the output end of the telescopic conveying assembly 113 is in abutment with the sorting area 150. The third conveying assembly 114 can be a belt conveying structure 1111, a roller conveying structure 1111, etc., which is not limited herein.

[0049] When the telescopic conveying assembly 113 is in the retracted position, the telescopic conveying assembly 113 is located on the same side or opposite sides of the passageway 160 with the unloading conveying assembly 111. Thus, when the telescopic conveying assembly 113 is in the retracted position, the telescopic conveying assembly 113 can be staggered with the passageway 160, so that personnel or transportation tools on the passageway 160 of the conveying device 100 can pass through.

[0050] It can be understood that, by abutting the input end of the unloading conveying assembly 111 of the conveying device 100 with the unloading area 140, the telescopic conveying assembly 113 is located above the passageway 160 when the telescopic conveying assembly 113 is in the extended position, the input end of the telescopic conveying assembly 113 is in abutment with the output end of the unloading conveying assembly 111, the output end of the telescopic conveying assembly 113 is in abutment with the sorting area 150, and the telescopic conveying assembly 113 is located on the same side or opposite sides of the passageway 160 with the unloading conveying assembly 111 when the telescopic conveying assembly 113 is in the retracted position.

[0051] When it is needed to convey the goods in the unloading area 140 to the sorting area 150, the telescopic conveying assembly 113 can be in the extended position, so that the input end of the telescopic conveying assembly 113 is in abutment with the output end of the unloading conveying assembly 111, and the output end of the telescopic conveying assembly 113 is in abutment with the sorting area 150. Then, the unloading conveying assembly 111 and the telescopic conveying assembly 113 are controlled to operate, so that the unloading conveying assembly 111 and the telescopic conveying assembly 113 can convey the goods in the unloading area 140 to the sorting area 150.

[0052] When there is a need for a person or a transport tool to pass through the channel 160 of the conveying device 100, the telescopic conveying assembly 113 can be controlled to be in the retracted position, and the telescopic conveying assembly 113 can be staggered with the channel 160, so that the person or the transport tool can pass through the channel 160 of the conveying device 100. Thus, the problem that the channel 160 of the conveying device 100 is blocked by the conveying assembly above the channel 160, and the person or the transport tool cannot pass through the channel 160 is solved, and the use of the conveying device 100 is more convenient.

[0053] Optionally, the output end of the telescopic conveying assembly 113 is connected with the sorting area 150, the input end of the telescopic conveying assembly 113 is disconnected with the output end of the unloading conveying assembly 111 when the telescopic conveying assembly 113 is in the retracted position, and the telescopic conveying assembly 113 and the unloading conveying assembly 111 are located on opposite sides of the channel 160, so that the channel 160 is not blocked by the telescopic conveying assembly 113 above the channel 160.

[0054] Specifically, the telescopic conveying assembly 113 includes a first telescopic conveying mechanism 1131 and a first fixed conveying mechanism 1132 distributed in sequence from the input end to the output end of the telescopic conveying assembly 113, the output end of the first fixed conveying mechanism 1132 is the output end of the telescopic conveying assembly 113, the input end of the first telescopic conveying mechanism 1131 is the input end of the telescopic conveying assembly 113, and the first telescopic conveying mechanism 1131 can slide relative to the first fixed conveying mechanism 1132 along the conveying direction of the telescopic conveying assembly 113.

[0055] When the first telescopic conveying mechanism 1131 slides relative to the first fixed conveying mechanism 1132 along the input end to the output end of the telescopic conveying assembly 113 to a position staggered with the channel 160, the telescopic conveying assembly 113 is in the retracted position; when the first telescopic conveying mechanism 1131 slides relative to the first fixed conveying mechanism 1132 along the output end to the input end of the telescopic conveying assembly 113 to above the channel 160, and the output end of the first telescopic conveying mechanism 1131 is connected with the input end of the first fixed conveying mechanism 1132, and the input end of the first telescopic conveying mechanism 1131 is connected with the output end of the unloading conveying assembly 111, the telescopic conveying assembly 113 is in the extended position.

[0056] In other embodiments, the input end of the telescopic conveying assembly 113 is connected with the output end of the unloading conveying assembly 111, the output end of the telescopic conveying assembly 113 is disconnected with the sorting area 150 when the telescopic conveying assembly 113 is in the retracted position, and the telescopic conveying assembly 113 and the unloading conveying assembly 111 are located on the same side of the channel 160, so that the channel 160 is not blocked by the telescopic conveying assembly 113 above the channel 160.

[0057] Specifically, the telescopic conveying assembly 113 comprises a second fixed conveying mechanism and a second telescopic conveying mechanism arranged in sequence along the input end to the output end of the telescopic conveying assembly 113, the input end of the second fixed conveying mechanism is the input end of the telescopic conveying assembly 113, the output end of the second telescopic conveying mechanism is the output end of the telescopic conveying assembly 113, and the second telescopic conveying mechanism can slide relative to the second fixed conveying mechanism along the conveying direction of the telescopic conveying assembly 113.

[0058] When the second telescopic conveying mechanism slides relative to the second fixed conveying mechanism along the output end to the input end of the telescopic conveying assembly 113 to a position offset from the channel 160, the telescopic conveying assembly 113 is in the retracted position; when the telescopic conveying mechanism slides relative to the second fixed conveying mechanism along the input end to the output end of the telescopic conveying assembly 113 to above the channel 160, and the output end of the second telescopic conveying mechanism is connected to the sorting area 150, and the input end of the second telescopic conveying mechanism is connected to the output end of the second fixed conveying mechanism, the telescopic conveying assembly 113 is in the extended position.

[0059] Optionally, the unloading conveying assembly 111 comprises a plurality of conveying structures 1111 connected in sequence along the input end to the output end of the unloading conveying assembly 111. The conveying speeds of the plurality of conveying structures 1111 gradually increase in the direction from the input end to the output end of the unloading conveying assembly 111. Thus, when the unloading conveying assembly 111 is conveying a plurality of goods, the spacing between adjacent two goods can be increased, so that the goods are more convenient to be conveyed to the sorting area 150 by the telescopic conveying assembly 113.

[0060] In other embodiments, the plurality of conveying structures 1111 operate independently of each other. Thus, when the unloading conveying assembly 111 is conveying a plurality of goods, when the telescopic conveying assembly 113 moves from the extended position to the retracted position, the plurality of conveying structures 1111 can be sequentially stopped in the order from the output end to the input end of the unloading conveying assembly 111. Thus, the goods on the unloading conveying assembly 111 can be prevented from falling from the output end, and as many goods as possible can be stacked on the unloading conveying assembly 111.

[0061] When the telescopic conveying assembly 113 moves to the extended position and starts to operate, the conveying speeds of the plurality of conveying structures of the unloading conveying assembly 111 can gradually increase in the direction from the input end to the output end of the unloading conveying assembly 111, so as to increase the spacing between adjacent two goods.

[0062] In the embodiments of the present application, the telescoping of the telescopic conveying assembly 113 of the conveying device 100 can be controlled by a controller or manually, and of course, when controlled by the controller, the conveying device 100 is more convenient to use.

[0063] Optionally, the conveying device 100 comprises a controller (not shown in the figure), which is electrically connected with the telescopic conveying assembly 113 and controls the operation state of the telescopic conveying assembly 113, so as to move the telescopic conveying assembly 113 to the extended position or the retracted position.

[0064] The conveying device 100 comprises a sensor 120, which is used to detect whether the channel 160 has a passing demand and outputs a corresponding first signal when detecting that the channel 160 has a passing demand.

[0065] The sensor 120 can actively detect the channel 160 to detect whether the channel 160 has a passing demand. For example, the sensor 120 is a photoelectric sensor 120, a proximity sensor 120, etc. The sensor 120 detects whether there is a person or a transportation tool in a preset area close to the telescopic conveying assembly 113 on the channel 160. If there is, it is detected that the channel 160 has a passing demand and a corresponding first signal is output. If not, it is detected that the channel 160 has no passing demand and a corresponding second signal is output.

[0066] In other embodiments, the sensor 120 is a button, a switch, a remote control receiver, etc. If the sensor 120 is triggered by a person on the channel 160, the sensor 120 detects that the channel 160 has a passing demand and outputs a corresponding first signal. If the sensor 120 is not triggered by a person on the channel 160, the sensor 120 detects that the channel 160 has no passing demand and outputs a corresponding second signal.

[0067] In the embodiments of the present application, the sensor 120 can be arranged on one side of the telescopic conveying assembly 113 along the length direction of the channel 160, or the sensor 120 can be arranged on both sides of the telescopic conveying assembly 113 along the length direction of the channel 160. Of course, the latter can detect both sides of the telescopic conveying assembly 113.

[0068] Optionally, the controller is electrically connected with the sensor 120 and the telescopic conveying assembly 113, respectively. The controller is used to receive the first signal and control the telescopic conveying assembly 113 to retract to the retracted position according to the first signal. Thus, when the channel 160 has a passing demand, the controller can automatically control the telescopic conveying assembly 113 to retract to the retracted position according to the first signal output by the sensor 120.

[0069] Optionally, the controller is used to receive the second signal and control the telescopic conveying assembly 113 to extend to the extended position according to the second signal. Thus, when the channel 160 has no passing demand, the controller can automatically control the telescopic conveying assembly 113 to extend to the extended position according to the second signal output by the sensor 120.

[0070] Optionally, the conveying device 100 comprises a detection assembly 121 for detecting whether there is an obstacle within a preset range of the channel 160 from the telescopic conveying assembly 113 and outputting a corresponding third signal when detecting the obstacle. The obstacle includes people, vehicles, and the like.

[0071] The detection assembly 121 is electrically connected to the controller, and the controller is configured to receive the third signal when controlling the telescopic conveying assembly 113 to extend, and control the telescopic conveying assembly 113 to stop extending according to the third signal. Thus, when the detection assembly 121 detects that there is an obstacle within the preset range of the channel 160 from the telescopic conveying assembly 113 during the process of controlling the telescopic conveying assembly 113 to extend, the controller can timely control the telescopic conveying assembly 113 to stop extending, so as to avoid the telescopic conveying assembly 113 colliding with the obstacle, and improve the safety of the conveying device 100.

The abnormal goods in the unloading area 140 that have abnormal sizes, weights, shapes, etc. are separately conveyed to the sorting area 150 by the first conveying structure 110 for sorting, so as to improve the conveying efficiency of the conveying device 100. Of course, the first conveying structure 110 can also be used to convey ordinary goods, which is not limited here.

[0080] The embodiment of the present application also provides a conveying device control method, which is mainly used for the conveying device 100 described above. As shown in Figure 2 The conveying device control method comprises steps 200 to 230, and the details are as follows:

[0081] 200, detecting whether the channel of the conveying device has a passing demand.

[0082] The sensor 120 described above can be used to detect whether the channel 160 of the conveying device 100 has a passing demand. Alternatively, a manual method can be used to detect whether the conveying device 100 has a passing demand.

[0083] 210, if the channel has a passing demand, detecting whether the telescopic conveying component of the conveying device is in an extended position.

[0084] When it is detected that the channel 160 has a passing demand, the telescopic conveying component 113 of the conveying device 100 can be detected to determine whether it is in an extended position. The controller can be used to detect whether the telescopic conveying component 113 is in an extended position. Specifically, the latest state of the controller controlling the telescopic conveying component 113 can be queried. When the controller last controls the telescopic conveying component 113 to extend, it is detected that the telescopic conveying component 113 is in an extended position; otherwise, it is detected that the telescopic conveying component 113 is in a retracted position. Alternatively, a manual method can be used to determine whether the telescopic conveying component 113 is in an extended position.

[0085] 220、if the telescopic conveying assembly is in the extended position, control the telescopic conveying assembly to retract to the retracted position, and control the unloading conveying assembly of the conveying device to stop running.

[0086] When the channel 160 has a passing demand and the telescopic conveying assembly 113 is in the extended position, the telescopic conveying assembly 113 can be staggered with the channel 160 by controlling the telescopic conveying assembly 113 to retract to the retracted position, so that personnel or a transport tool on the channel 160 of the conveying device 100 can pass. At the same time, by controlling the unloading conveying assembly 111 of the conveying device 100 to stop running, it can be avoided that the unloading conveying assembly 111 continues to convey goods, causing the goods to fall from the output end of the unloading conveying assembly 111.

[0087] In the embodiment of the application, the conveying device control method can further include the following steps:

[0088] 230、if the channel has no passing demand, detect whether the telescopic conveying assembly of the conveying device is in the extended position.

[0089] The specific way of detecting whether the telescopic conveying assembly 113 of the conveying device 100 is in the extended position can refer to the above-mentioned way, which will not be described here again.

[0090] 240、if the telescopic conveying assembly is not in the extended position, control the telescopic conveying assembly to extend to the extended position.

[0091] When the channel 160 has no passing demand and the telescopic conveying assembly 113 is not in the extended position, by controlling the telescopic conveying assembly 113 to extend to the extended position, the input end of the telescopic conveying assembly 113 can be timely docked with the output end of the unloading conveying assembly 111, so that the goods on the unloading conveying assembly 111 can be conveyed to the telescopic conveying assembly 113, thereby improving the conveying efficiency of the conveying device 100.
