Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and more specifically, to a warehousing logistics sorting system. Background Art

[0002] With the rise of e-commerce, the logistics industry has developed rapidly. When goods are transported to a transfer station for warehousing, the goods need to be sorted and sent to different locations, which requires the use of sorting devices. Currently, when sorting goods, the goods are generally disinfected. When sorting existing goods, the goods are usually directly placed on the conveyor belt and disinfectant is sprayed onto the surface of the goods manually. Manual spraying is time-consuming and laborious, and the side of the goods in contact with the conveyor belt is not easily disinfected, thus easily causing the risk of virus transmission. Therefore, it needs to be improved. Summary of the Invention

[0003] The purpose of the present invention is to provide a warehousing logistics sorting system to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A warehousing logistics sorting system includes a first conveyor belt, a second conveyor belt, and a flat plate. The flat plate is located between the output end of the first conveyor belt and the input end of the second conveyor belt. The upper belt surface of the second conveyor belt is higher than the upper belt surface of the first conveyor belt. The upper surface of the flat plate is at the same height as the upper belt surface of the first conveyor belt. It further includes a disinfection chamber arranged above the first conveyor belt and the second conveyor belt. The input end of the first conveyor belt and the output end of the second conveyor belt are both outside the disinfection chamber. A plurality of spraying pipes are installed in the disinfection chamber;

[0006] A barcode scanner is installed on one side of the disinfection chamber located on the side of the second conveyor belt. A plurality of conveying racks are arranged on both sides of the second conveyor belt. A plurality of weighing and sorting mechanisms are arranged on the second conveyor belt. The weighing and sorting mechanism includes a weighing plate and a third conveyor belt. Third side plates are fixedly connected to both sides of the top of the weighing plate. The third conveyor belt is arranged between the two third side plates. The third conveyor belt is perpendicular to the second conveyor belt. The third conveyor belt conveys the goods to the corresponding conveying racks;

[0007] A turning mechanism is arranged on one side of the third conveyor belt for turning the goods on the flat plate and sending them onto the third conveyor belt. When the third conveyor belt is above the second conveyor belt, the turning mechanism is located on the side of the third conveyor belt close to the flat plate.

[0008] Preferably, it further includes two first side plates. Two first conveyor rollers are rotatably installed between the two first side plates. The first conveyor belt is sleeved on the two first conveyor rollers. A plurality of first support feet are fixedly connected to the bottom of the first side plate.

[0009] Preferably, both sides of the flat plate are fixedly connected to two first side plates respectively. A through hole is formed in the top of the flat plate, and a baffle is slidably arranged in the through hole. A fixed block is fixedly connected to the bottom end of the baffle, and a cylinder is installed at the bottom of the flat plate. The end of the piston rod of the cylinder is fixedly connected to the fixed block.

[0010] Preferably, it further includes two second side plates. Two second conveying rollers are rotatably installed between the two second side plates. The second conveyor belt is sleeved on the two second conveying rollers. A plurality of second support feet are fixedly connected to the bottom of the second side plate. The first side plate and the second side plate on the same side are fixedly connected.

[0011] Preferably, it further includes a driving assembly for simultaneously driving the first conveying roller and the second conveying roller to rotate. The driving assembly includes a first main pulley, a first driven pulley, a first belt, a first motor, a second main pulley, a second driven pulley and a second belt. One end of the first conveying roller at the second conveyor belt penetrates through the first side plate, and one end of the second conveying roller at the first conveyor belt penetrates through the second side plate. One end of the first conveying roller at the second conveyor belt and one end of the second conveying roller at the first conveyor belt are on the same side. The first driven pulley and the second main pulley are both fixedly connected to the first conveying roller at the second conveyor belt. The second driven pulley is fixedly connected to one end of the second conveying roller at the first conveyor belt. The first motor is installed on the first side plate. The first main pulley is fixedly connected to the end of the output shaft of the first motor. The first belt is sleeved on the first main pulley and the first driven pulley. The second belt is sleeved on the second main pulley and the second driven pulley.

[0012] Preferably, a water guide pipe is fixedly connected to the top of the disinfection chamber. It further includes a connecting pipe for connecting the water guide pipe and the spraying pipe. A plurality of atomizing nozzles are installed on the spraying pipe. A water pump is installed on the side wall of the disinfection chamber. The water inlet end of the water pump is connected to a first water pipe, and the water outlet end of the water pump is connected to a second water pipe. The end of the second water pipe away from the water pump is connected to the water guide pipe.

[0013] Preferably, the weighing and sorting mechanism further includes a bottom plate and a connecting strip. The weighing plate is slidably arranged on the bottom plate. A pressure sensor is installed on the top of the bottom plate. The bottom inner wall of the weighing plate abuts against the pressure sensor. The connecting strip is fixedly connected to the bottom of the bottom plate. The side of the connecting strip away from the bottom plate is fixedly connected to the second conveyor belt. Two third conveying rollers are rotatably installed between two third side plates. The third conveyor belt is sleeved on the two third conveying rollers. A third motor is installed on one of the third side plates. The end of the output shaft of the third motor is coaxially connected to the end of one of the third conveying rollers.

[0014] Preferably, the flipping mechanism includes a rotating shaft, a second motor, and a plurality of flap plates fixedly connected to the rotating shaft. When the third conveyor belt is above the second conveyor belt, two mounting seats are fixedly connected to the third side plate close to the flat plate. The rotating shaft is rotatably mounted on the two mounting seats, and the second motor is mounted on one of the mounting seats. The end of the output shaft of the second motor is coaxially connected to one end of the rotating shaft; a plurality of through grooves adapted to the flap plates are formed on the flat plate.

[0015] Preferably, a groove is formed in the inner wall of one of the through grooves, and an infrared sensor is installed in the groove; when the infrared sensor detects that the flap plate enters the through groove, the air cylinder pushes the fixed block to move the top end of the baffle plate into the through hole.

[0016] Preferably, the conveying frame is fixedly connected to the second side plate, and a plurality of rollers are rotatably mounted on the conveying frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] First of all, after the goods are conveyed to the disinfection chamber on the first conveyor belt, the disinfectant sprayed by the atomizing nozzle can disinfect all sides of the goods except the side in contact with the first conveyor belt at the bottom. When the goods are flipped and conveyed to the third conveyor belt by the flipping mechanism, the side of the goods in contact with the first conveyor belt at the bottom is flipped forward. At this time, the disinfectant sprayed by the atomizing nozzle can disinfect the side of the goods in contact with the first conveyor belt at the bottom, so that the goods can be thoroughly disinfected and the risk of virus transmission can be avoided.

[0019] Secondly, when the goods are flipped and conveyed to the third conveyor belt, the goods will exert pressure on the third conveyor belt, and the weighing plate will squeeze the pressure sensor. When the pressure sensor detects that the pressure value is greater than or equal to the first set value, the pressure sensor will transmit a signal to the controller, and the controller controls the second motor to work, driving the rotating shaft and the flap plate to rotate, and rotating the flap plate to a horizontal state so that the flap plate does not contact the bottom surface of the goods, so that the disinfectant can be better sprayed on the bottom of the goods, further strengthening the disinfection of the bottom of the goods.

[0020] Thirdly, when a flap plate enters the through groove and the infrared sensor detects that the flap plate enters the through groove, it will transmit a signal to the controller. The controller controls the air cylinder to push the fixed block to drive the top end of the baffle plate to move into the through hole. At this time, under the conveying force of the first conveyor belt, the goods will move forward along the flat plate to the position of the third conveyor belt. When the goods are lifted and flipped by the flap plate, the goods are in contact with the third conveyor belt, and the goods will not fall down to the surface of the third conveyor belt. For some fragile items, it is not easy for the goods to be damaged due to falling.

[0021] Finally, the barcode scanner can scan the barcodes on the goods to identify the locations where the goods should be transported. When the third conveyor belt moves to the conveyor rack at the corresponding location, the third motor operates to drive the third conveyor belt to convey the goods to the conveyor rack, thus realizing the sorting of the goods' transportation locations; when the goods are on the third conveyor belt, when the barcode scanner has identified the location where the goods are to be transported and the pressure sensor detects the weight of the goods, when the pressure value detected by the pressure sensor is greater than or equal to the second set value, a signal will be transmitted to the controller, and the controller will control the third motor to rotate clockwise, thereby driving the third conveyor belt to rotate clockwise and conveying the goods to the conveyor rack on one side of the corresponding location; when the pressure value detected by the pressure sensor is less than the second set value and greater than or equal to the first set value, a signal will be transmitted to the controller, and the controller will control the third motor to rotate counterclockwise, thereby driving the third conveyor belt to rotate counterclockwise and conveying the goods to the conveyor rack on the other side of the corresponding location, so as to perform weight sorting on the goods transported to the same location, greatly improving the sorting efficiency.

[0040] The present invention provides a technical solution:

[0041] A warehousing and logistics sorting system, please refer to Figures 1 - 3 , which includes a first conveyor belt 10, a second conveyor belt 20 and a flat plate 30. The flat plate 30 is located between the output end of the first conveyor belt 10 and the input end of the second conveyor belt 20. The conveying directions of the first conveyor belt 10 and the second conveyor belt 20 are the same. The upper belt surface of the second conveyor belt 20 is higher than the upper belt surface of the first conveyor belt 10. The upper surface of the flat plate 30 is at the same height as the upper belt surface of the first conveyor belt 10. The first conveyor belt 10 is used to convey goods onto the flat plate 30.

[0042] Please refer to Figures 4 - 7 , and it further includes two first side plates 12. Two first conveyor rollers 11 are rotatably installed between the two first side plates 12. The first conveyor belt 10 is sleeved on the two first conveyor rollers 11. The bottom of the first side plate 12 is fixedly connected with a plurality of first support feet 13. The first support feet 13 are used to stably support the first side plate 12. Both sides of the flat plate 30 are fixedly connected with the two first side plates 12 respectively; it further includes two second side plates 22. Two second conveyor rollers 21 are rotatably installed between the two second side plates 22. The second conveyor belt 20 is sleeved on the two second conveyor rollers 21. The bottom of the second side plate 22 is fixedly connected with a plurality of second support feet 23. The first side plate 12 and the second side plate 22 on the same side are fixedly connected together.

[0043] Please refer to Figure 2 and Figure 14, further comprising a driving assembly for simultaneously driving the first conveying roller 11 and the second conveying roller 21 to rotate. The driving assembly includes a first main pulley 80, a first driven pulley 81, a first belt 82, a first motor 83, a second main pulley 84, a second driven pulley 85 and a second belt 86. One end of the first conveying roller 11 located at the second conveyor belt 20 passes through the first side plate 12, and one end of the second conveying roller 21 located at the first conveyor belt 10 passes through the second side plate 22. One end of the first conveying roller 11 located at the second conveyor belt 20 and one end of the second conveying roller 21 located at the first conveyor belt 10 are on the same side. The first driven pulley 81 and the second main pulley 84 are both fixedly connected to the first conveying roller 11 located at the second conveyor belt 20. The second driven pulley 85 is fixedly connected to one end of the second conveying roller 21 located at the first conveyor belt 10. The first motor 83 is fixedly installed on the first side plate 12 by bolts. The first main pulley 80 is fixedly connected to the end of the output shaft of the first motor 83. The first belt 82 is sleeved on the first main pulley 80 and the first driven pulley 81. The second belt 86 is sleeved on the second main pulley 84 and the second driven pulley 85.

[0044] Starting the first motor 83 to work can drive the first main pulley 80 to rotate, thereby driving the first belt 82 and the first driven pulley 81 to rotate, and further driving the first conveying roller 11 and the second main pulley 84 to rotate. When the first conveying roller 11 rotates, it can drive the first conveyor belt 10 to move towards the flat plate 30. The rotation of the second main pulley 84 can drive the second belt 86 and the second driven pulley 85 to rotate, thereby driving the second conveying roller 21 to rotate, so as to drive the second conveyor belt 20 to move. The driving and conveying directions of the second conveyor belt 20 and the first conveyor belt 10 are the same; the driving of the second conveyor belt 20 and the first conveyor belt 10 shares one first motor 83, making the synchronization of the conveying of the second conveyor belt 20 and the first conveyor belt 10 better, and only using one first motor 83 saves more electric energy.

[0045] For the convenience of disinfecting the goods, please refer to Figures 1 - 3 , Figure 13 , further comprising a disinfection chamber 50 provided above the first conveyor belt 10 and the second conveyor belt 20. The disinfection chamber 50 straddles the first conveyor belt 10 and the second conveyor belt 20. The bottom of the disinfection chamber 50 is fixedly connected to the first side plate and / or the second side plate. The input end of the first conveyor belt 10 and the output end of the second conveyor belt 20 are both outside the disinfection chamber 50. Only part of the first conveyor belt 10 and the second conveyor belt 20 is located inside the disinfection chamber 50. A plurality of spray pipes 55 are installed in the disinfection chamber 50; when the goods are placed at the input end of the first conveyor belt 10, the goods will be conveyed by the first conveyor belt 10 into the disinfection chamber 50, and the disinfectant liquid sprayed by the spray pipes 55 can disinfect the surface of the goods.

[0046] Specifically, please refer to Figure 13 , a water guide pipe 54 is fixedly connected to the top of the disinfection bin 50. Both ends of the water guide pipe 54 are closed. A connecting pipe 57 for connecting the water guide pipe 54 and the spraying pipe 55 is also included. The connecting pipe 57 passes through the disinfection bin 50. The top end of the connecting pipe 57 is connected to the water guide pipe 54. A number of atomizing nozzles 56 are installed on the spraying pipe 55. Each atomizing nozzle 56 is arranged at a different angle along the circumferential direction of the spraying pipe 55, which is convenient for more thorough disinfection of the surface of the goods. A water pump 51 is fixedly installed on the side wall of the disinfection bin 50 through bolts. The water inlet end of the water pump 51 is connected to a first water pipe 52, and the water outlet end of the water pump 51 is connected to a second water pipe 53. One end of the second water pipe 53 far from the water pump 51 is connected to the water guide pipe 54; the second water pipe 53, the water guide pipe 54, the connecting pipe 57, and the spraying pipe 55 are communicated in sequence.

[0047] During use, one end of the first water pipe 52 far from the water pump 51 is connected to the external disinfectant. The water pump 51 is started to work, and the disinfectant can be pumped out. The disinfectant passes through the first water pipe 52, the water pump, the second water pipe 53, the water guide pipe 54, the connecting pipe 57, the spraying pipe 55, and the atomizing nozzles 56 in sequence, and finally is sprayed on the surface of the goods from the atomizing nozzles 56.

[0048] Please refer to Figure 11 , Figure 12 , a number of weighing and sorting mechanisms are provided on the second conveyor belt 20. The weighing and sorting mechanism includes a weighing plate 42, a bottom plate 43, a connecting strip 44, and a third conveyor belt 40. Third side plates 41 are fixedly connected to both sides of the top of the weighing plate 42. The third conveyor belt 40 is arranged between the two third side plates. The third conveyor belt 40 is perpendicular to the second conveyor belt 20. The weighing plate 42 is slidably arranged on the bottom plate 43. Specifically, a groove is formed by the bottom of the bottom plate 43 recessing upward. Sliders 420 are fixedly connected to both sides of the groove. Slide grooves 430 are formed on both sides of the bottom plate 43. The sliders 420 are slidably arranged in the slide grooves 430; a pressure sensor 45 is installed on the top of the bottom plate 43. The bottom of the inner wall of the weighing plate 42 is always in contact with the pressure sensor 45. The connecting strip 44 is fixedly connected to the bottom of the bottom plate 43. One side of the connecting strip 44 far from the bottom plate 43 is fixedly connected to the second conveyor belt 20. Two third conveyor rollers are rotatably installed between the two third side plates. The third conveyor belt is sleeved on the two third conveyor rollers. A third motor is installed on one of the third side plates. The output shaft end of the third motor is coaxially connected to the end of one of the third conveyor rollers.

[0049] In order to facilitate the transfer of goods from the flat plate 30 to the third conveyor belt by flipping, a flipping mechanism for flipping the goods on the flat plate 30 onto the third conveyor belt 40 is provided on one side of the third conveyor belt 40. When the third conveyor belt 40 is located above the second conveyor belt 20, the flipping mechanism is located on the side of the third conveyor belt 40 close to the flat plate 30; the flipping mechanism includes a rotating shaft 47, a second motor 49, and a plurality of flap plates 48 fixedly connected to the rotating shaft 47. When the third conveyor belt 40 is located above the second conveyor belt 20, two mounting seats 46 are fixedly connected to the third side plate 41 on the side close to the flat plate 30. The rotating shaft 47 is rotatably installed on the two mounting seats 46, and the second motor 49 is fixedly installed on one of the mounting seats 46 by bolts. The end of the output shaft of the second motor 49 is coaxially connected to one end of the rotating shaft 47; a plurality of through grooves 300 adapted to the flap plates 48 (which means that the size of the flap plates 48 matches the size of the through grooves 300, the number of the flap plates 48 is the same as the number of the through grooves 300, and the positions of the flap plates 48 also correspond one by one to the positions of the through grooves 300) are provided on the flat plate 30.

[0050] When there is no goods on the third conveyor belt 40, the flap plates 48 are in a vertical state (as Figure 11 shown). As the second conveyor belt 20 drives, it drives the flipping mechanism to move. When the flap plates 48 move into the through grooves 300, the flap plates 48 will drag and lift the bottom of the goods on the flat plate 30 when moving upward. When the third conveyor belt 40 moves above the second conveyor belt 20, the goods are flipped and conveyed onto the third conveyor belt 40, and the bottom of the goods is flipped towards the first conveyor belt 10. At this time, when the atomizing nozzle 56 sprays disinfectant, the bottom of the goods can be disinfected, avoiding the bottom of the goods from always contacting the first conveyor belt 10 without being disinfected, making the disinfection of the goods more thorough, effectively avoiding the spread of the virus, and greatly improving the practicability of the device.

[0051] It should be noted that when the goods are conveyed onto the third conveyor belt 40, the goods will exert pressure on the third conveyor belt 40, and the weighing plate 42 will squeeze the pressure sensor 45. When the pressure sensor 45 detects that the pressure value is greater than or equal to the first set value, the pressure sensor 45 will transmit a signal to the controller, and the controller controls the second motor 49 to work, driving the rotating shaft 47 and the flap plates 48 to rotate, turning the flap plates 48 to a horizontal state so that the flap plates 48 do not contact the bottom surface of the goods, allowing the disinfectant to be better sprayed on the bottom of the goods, further strengthening the disinfection of the bottom of the goods; when the goods are conveyed out of the third conveyor belt 40, the pressure value detected by the pressure sensor 45 will be less than the first set value. At this time, the pressure sensor 45 transmits a signal to the controller, and the controller controls the second motor 49 to work, driving the rotating shaft 47 and the flap plates 48 to rotate, turning the flap plates 48 to a vertical state.

[0052] It should be noted that the width of the goods conveyed in the present invention is greater than the width of the flat plate 30. When the goods are conveyed from the first conveyor belt 10 to the position of the flat plate 30, the goods are placed on both the first conveyor belt 10 and the flat plate 30 at the same time.

[0053] To prevent the goods from falling off during conveyance on the flat plate 30, please refer to Figures 8 - 10 , a through hole 302 is provided in the top of the flat plate 30, a baffle 31 is slidably provided in the through hole 302, a fixed block 32 is fixedly connected to the bottom end of the baffle 31, a cylinder 33 is fixedly installed at the bottom of the flat plate 30 by bolts, and the end of the piston rod of the cylinder 33 is fixedly connected to the fixed block 32. When the flap 48 does not enter the through groove 300, the cylinder 33 pushes the fixed block 32 to drive the top end of the baffle 31 to move above the top of the flat plate 30 (as Figure 8 shown). When the goods are conveyed from the first conveyor belt 10 to the flat plate 30, the baffle 31 can block the goods to prevent the goods from continuing to move forward along the flat plate 30 and falling off the flat plate 30.

[0054] Please refer to Figures 8 - 10 , a groove 301 is provided in the inner wall of one of the through grooves 300, and an infrared sensor 34 is installed in the groove 301; when the infrared sensor 34 detects that the flap 48 enters the through groove 300, the cylinder 33 pushes the fixed block 32 to move the top end of the baffle 31 into the through hole 302; when a flap 48 enters the through groove 300 and the infrared sensor 34 detects that the flap 48 enters the through groove 300, it will transmit a signal to the controller, and the controller controls the cylinder 33 to push the fixed block 32 to drive the top end of the baffle 31 to move into the through hole 302. At this time, under the conveying force of the first conveyor belt 10, the goods will move forward along the flat plate 30 to the position of the third conveyor belt 40. At this time, when the goods are lifted and flipped by the flap 48, the goods are in contact with the third conveyor belt 40, and the goods will not fall down onto the surface of the third conveyor belt 40. For some fragile items, it is not easy for the goods to be damaged due to falling; when the flap 48 leaves the through groove 300 and the infrared sensor 34 does not detect the flap 48, it will transmit a signal to the controller, and the controller controls the cylinder 33 to push the fixed block 32 to drive the top end of the baffle 31 to move above the top of the flat plate 30 to facilitate blocking the subsequent goods.

[0055] A barcode scanner 6 is installed on one side of the disinfection chamber 50 located on the second conveyor belt 20. A number of conveying frames 70 are provided on both sides of the second conveyor belt 20. The conveying frames 70 are fixedly connected to the second side plate 22, and a number of rollers 71 are rotatably installed on the conveying frames 70; specifically, the conveying frames 70 are symmetrically arranged on both sides of the second conveyor belt 20. The goods on the two corresponding conveying frames 70 on both sides are conveyed to the same location, and the two corresponding conveying frames 70 on both sides are used to further sort the goods of different weights at the same location. The third conveyor belt 40 conveys the goods to the corresponding conveying frames 70.

[0056] When the goods are conveyed out of the disinfection bin 50 on the third conveyor belt 40, the barcode scanner 6 can scan the barcode on the goods to identify the location where the goods should be conveyed (when the goods are placed on the first conveyor belt 10, one side of the barcode faces forward. When the goods are flipped and conveyed onto the third conveyor belt 40, the barcode faces upward, facilitating scanning by the barcode scanner 6). When the third conveyor belt 40 moves to the conveyor rack 70 at the corresponding location, the third motor operates to drive the third conveyor belt 40 to convey the goods onto the conveyor rack 70, thereby realizing the sorting of the goods' transportation locations.

[0057] When the goods are on the third conveyor belt 40, when the barcode scanner 6 has identified the location where the goods are to be conveyed and the pressure sensor 45 detects the weight of the goods, when the pressure value detected by the pressure sensor 45 is greater than or equal to the second set value, a signal will be transmitted to the controller, and the controller will control the third motor to rotate clockwise, thereby driving the third conveyor belt 40 to rotate clockwise and conveying the goods onto the conveyor rack 70 on one side of the corresponding location; when the pressure value detected by the pressure sensor 45 is less than the second set value and greater than or equal to the first set value, a signal will be transmitted to the controller, and the controller will control the third motor to rotate counterclockwise, thereby driving the third conveyor belt 40 to rotate counterclockwise and conveying the goods onto the conveyor rack 70 on the other side of the corresponding location, so as to perform weight sorting on the goods transported to the same location, greatly improving the sorting efficiency; when the goods are conveyed away from the third conveyor belt 40, the pressure value detected by the pressure sensor 45 is less than the first set value, and at this time the controller will control the third motor to stop working, saving electrical energy.

[0058] When the pressure sensor 45 detects that the pressure value is greater than or equal to the first set value and the barcode scanner 6 fails to identify the location where the goods are to be conveyed, the third motor does not operate.

[0059] It should be added that the second motor, the third motor, the pressure sensor, the air cylinder, the barcode scanner, and the infrared sensor are all electrically connected to the controller.
