Description

Technical Field

[0001] The present invention belongs to the technical field of logistics sorting, and specifically relates to an automated logistics item sorting device and sorting method for logistics. Background Art

[0002] With the rapid development of the logistics industry, people send express parcels more and more frequently, which greatly promotes the development of the logistics industry. However, with the development of the logistics industry, a problem also arises, that is, the increase in logistics items. Therefore, with the increase in logistics items, a large number of logistics items are stacked together, and a sorting device is needed to achieve material sorting. In the existing automated logistics item sorting devices for logistics, when sorting, they usually use a limiting component in combination with a sensor and a control system based on PLC control to achieve the sorting of logistics items of different volumes. By limiting the volume and height of the logistics items and cooperating with a pressure sensor to start the electric push rod, the sorting and transportation of large-volume logistics items are realized. However, in fact, after sorting logistics items of different volumes, the sorting step is completed, and it is actually impossible to further sort according to the specific situation of the logistics items. Therefore, additional sorting operations are still required after obtaining the sorted logistics items, and there are still many deficiencies in the comprehensive sorting of logistics items.

[0003] In addition, in the existing automated logistics item sorting devices for logistics, when sorting large-volume logistics items, since the logistics items on the conveyor belt move forward by the driving force of the belt and compress the pressure sensor, when the system controls the electric push rod to act and push the logistics items on the conveyor belt from the side, the actual logistics items still have a moving trend in the forward direction when they are laterally stressed. There is a large damping when the actual large-volume logistics items move laterally, and there is rotation of the logistics items during the pushing for sorting. The actual pushing effect for sorting is poor, and there are situations of tipping and offset of the logistics items. The sorting stability of the actual large-volume logistics items is poor.

[0008] Preferably, the number of the bottom frames and the electric push rods is two each. The two electric push rods correspond to the two flip-type sorting tables one by one, and the electric push rods are located below the flip-type sorting tables.

[0010] Preferably, the push-type sorting mechanism includes a side seat, a distribution frame, a sleeve, a push rod, and a second spring.

The connecting frame is fixedly connected to the end face of the movable plate and is communicated with the first rectangular opening. The air outlet is formed in the bottom surface of the connecting frame and inclines downward towards the first conveyor.

[0013] The present invention also provides a sorting method for an automated logistics part sorting device for logistics, including the following sorting steps:

[0014] First step: Start the air supply mechanism, so that the air compressor in the air supply mechanism passes air into the communicating plate through the air pipe, enters the communicating hole along the top hole in the communicating plate, and passes into the second rectangular opening and the second rectangular opening of the movable plate, and passes into the connecting frame and blows downward towards the first conveyor, and start the first conveyor, the second conveyor, and the third conveyor;

[0015] Step 2: Logistics items of different large volumes, small volumes, large masses, and small masses are placed on the first conveyor and transported towards the front end of the rack plate through the top belt. When the small-volume logistics item moves to the tail of the first conveyor, it is pushed onto the middle inclined platform and slides down along the middle inclined platform to the second conveyor, and continues to be transported forward. When the large-volume logistics item slides down along the middle inclined platform, it contacts the communication plate, and at the same time compresses the communication mechanism sleeved in the middle of the communication plate, causing the movable plate in the communication mechanism to move and the through holes on its side to communicate with the side holes in the communication plate. As the movable plate moves, while sealing the communication hole, the gas is input into the middle pipe through the side holes and through holes in the communication plate and introduced into the push-type sorting mechanism, causing the push rod in the push-type sorting mechanism to move from one side of the large-volume logistics item, and pushing the large-volume logistics item to slide from one side of the middle inclined platform to the other side and automatically slide onto the third conveyor when there is no limit of the communication plate, and be transported away along the third conveyor, completing the sorting of large-volume logistics items;

[0016] Step 3: When the second conveyor and the third conveyor transport small-volume and large-volume logistics items respectively, as the logistics items slide down to the top of the flip-type sorting table through the top of the guiding mechanism, at this time the logistics items are blocked by the baffle limit. At this time, the component force of the logistics item along the sorting inclined platform acts on the pressure sensor, and the pressure sensor transmits the sensed pressure signal to the control system according to the set pressure value. When the control system recognizes that the pressure value exceeds the set value, it controls the corresponding electric push rod to rise and push the flip-type sorting table to flip, causing the logistics item with a large mass on the upper part to slide down along one side. When the control system recognizes that the pressure value does not reach the set value, it recognizes the logistics item with a light mass and causes the corresponding electric push rod to contract. As the bottom of the flip-type sorting table loses the supporting force, the torsion spring in the corresponding flip-type sorting table elastically acts and drives the sorting inclined platform to flip in the reverse direction, causing the logistics item with a light mass to slide down to the other side, completing the sorting of logistics items of different masses.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention utilizes an intermediate inclined platform placed between a first conveyor and a second conveyor with a height difference, and cooperates with a connecting plate above the intermediate inclined platform to achieve the limit and block of large-volume logistics items, ensuring the downward transportation of small-volume logistics items. At the same time, in cooperation with the power air provided by the air supply mechanism, after the large-volume logistics item slides down along the top of the intermediate inclined platform and compresses the connecting mechanism, the through holes in the connecting mechanism are connected to the inside of the connecting plate, so that the fed gas is introduced into the push-type sorting mechanism through the intermediate pipe, realizing the pushing of the large-volume logistics item static on the top of the intermediate inclined platform, moving from one side of the intermediate inclined platform to the other side, and then being smoothly sorted under the condition of losing the limit of the connecting plate and sliding into the third conveyor for sorting and transportation. At the same time, in cooperation with the guiding mechanism installed at the front ends of the second conveyor and the third conveyor, the corresponding logistics items are guided and slid onto the flip-type sorting table, and the pressure sensor on the flip-type sorting table transmits signals to the control system. According to the set signal value in the control system, it is judged whether the quality of the logistics item exceeds the set value. When it exceeds the set value, the corresponding electric push rod below is controlled to act and push the flip-type sorting table to flip, turning the logistics item with a large mass to one side. When the signal value is lower than the set value, the electric push rod is controlled to contract, and then with the elastic reset of the torsion spring in the flip-type sorting table, the flip-type sorting table is reversely flipped, and the logistics item with a light mass is turned to the other side, completing the sorting of heavy and light logistics items. Similarly, a set of pressure sensors and electric push rods cooperate with the control system to complete the action process. By changing the arrangement position and adding an air supply mechanism and a connecting mechanism, the automatic sorting of logistics items of different volumes is realized, and then the secondary sorting of heavy and light logistics items is further completed. During the actual pre-stage sorting of different volumes, there is no need to introduce new sensor components. Under the reasonable arrangement of the existing sensor positions, double sorting is completed, and the use effect is good.

[0019] 2. The present invention utilizes an intermediate inclined platform arranged between a first conveyor and a second conveyor with a height difference. During the actual sorting process of logistics items of different volumes, the large-volume logistics items to be sorted are static on the top surface of the inclined intermediate inclined platform. Thus, when the push rod is pushed to move and push the logistics item under the action of pneumatic thrust, the actual logistics item moves horizontally while being stationary, effectively avoiding interference with the horizontal sorting of the logistics item under the friction and push of the belt in the conveyor, making the pushing of the actual logistics item more stable and reliable, avoiding deflection during the pushing of the logistics item, and improving the sorting effect.

[0020] 3. By reusing the flowing air provided by the air supply mechanism, which is started before the logistics sorting, as different types of logistics items are transported on the first conveyor, in cooperation with the connecting frame whose top is parallel to the middle inclined table, the air outlet is inclined towards the logistics items transported at the top of the first conveyor for wind blowing and dust removal, realizing the blowing and dust removal of the logistics items during the logistics transportation, while blowing out the dust at the top of the first conveyor, maintaining the cleanliness of the logistics items and the first conveyor, and at the same time cooperating with the flowing air formed by the logistics sorting equipment environment to improve the comfort of the monitoring personnel and reduce the equipment environment temperature.

The guiding inclined plate 113 is fixedly inclined on the top surface of the guiding table 111. A flip-type sorting table 12 is rotatably sleeved at the front end of the guiding table 111. The flip-type sorting table 12 includes a sorting inclined table 121, a pressure sensor 122, a sleeve rod 123, a sleeve ring 124, and a torsion spring 125. The pressure sensor 122 is fixedly installed on the top surface of the sorting inclined table 121. A partition plate 13 is fixedly connected to the end surface of the guiding table 111. Baffle plates 14 are fixedly connected to both sides of the partition plate 13. The number of the flip-type sorting tables 12 is two and they respectively correspond to the front ends of the second conveyor 7 and the third conveyor 8. An air supply mechanism 23 and a mounting column 17 are respectively fixedly installed on the outer side surfaces of the two frame plates 1. A mounting rod 18 is fixedly connected to the side surface of the mounting column 17. A communication plate 19 located above the intermediate inclined table 9 is fixedly connected to the end surface of the mounting rod 18. A top hole 21 and a side hole 20 that communicate with each other are respectively opened on the top surface and the side surface of the communication plate 19. The top hole 21 is communicated with the air supply mechanism 23. A socket 25 is opened on the front surface of the communication plate 19. A communication mechanism 22 is movably sleeved inside the socket 25. The communication mechanism 22 includes a movable plate 221, a through hole 222, a connecting plate 223, and a first spring 224. The movable plate 221 is movably sleeved in the socket 25. The connecting plate 223 is fixedly connected to the rear end of the movable plate 221 and is located on the back surface of the communication plate 19. The first spring 224 is fixedly connected between the connecting plate 223 and the communication plate 19. A push-type sorting mechanism 24 is fixedly installed on the side surface of one frame plate 1. An intermediate pipe 28 is fixedly connected and communicated between the push-type sorting mechanism 24 and the communication plate 19. One end of the intermediate pipe 28 is communicated with the side hole 20.

[0037] First Embodiment: Start the first conveyor 6, the second conveyor 7, and the third conveyor 8. Place logistics items of different large volumes, small volumes, large masses, and small masses on the first conveyor 6 and transport them towards the front end of the frame plate 1 through the top belt. When the small-volume logistics item moves to the tail of the first conveyor 6, it is pushed onto the middle inclined table 9 and slides down along the middle inclined table 9 to the second conveyor 7, and continues to be transported forward. Keep the air supply mechanism 23 started, and the air compressor 232 transports gas into the communication plate 19. When the large-volume logistics item contacts the communication plate 19 while sliding down along the middle inclined table 9, it cannot continue to be transported, and compresses the communication mechanism 22 sleeved in the middle of the communication plate 19, causing the movable plate 221 in the communication mechanism 22 to move and the through hole 222 on its side to communicate with the side hole 20 in the communication plate 19. The gas in the communication plate 19 enters the middle pipe 28 through the side hole 20 and the through hole 222, and is introduced into the push-type sorting mechanism 24, so that gas enters the distribution box 242 in the push-type sorting mechanism 24, and the gas enters the upper and lower two sets of sleeves 243. In the sleeves 243, the push rod 244 moves from one side of the large-volume logistics item and pushes the large-volume logistics item to slide from one side of the middle inclined table 9 to the other side, and automatically slides down to the third conveyor 8 when there is no limit of the communication plate 19, and is transported away along the third conveyor 8. After the large-volume logistics item is sorted, the communication mechanism 22 resets, and the through hole 222 and the side hole 20 are gradually staggered. During the staggering process, the gas in the communication plate 19 is led out through the first rectangular opening 225 and the second rectangular opening 226 on the movable plate 221 in the movable plate 221, and cooperates with the elastic reset of the second spring 245 to make the air pressure in the sleeve 243 partial vacuum, pull the push rod 244 to reset, and continue sorting. After the sorting of the large-volume logistics item is completed, when the second conveyor 7 and the third conveyor 8 transport small-volume and large-volume logistics items respectively, as the logistics items slide down to the top of the flip-type sorting table 12 through the top of the guiding mechanism 11, at this time, the logistics items are limited and blocked by the baffle 14. At this time, the component force of the logistics item along the sorting inclined table 121 acts on the pressure sensor 122, and the pressure sensor 122 transmits the sensed pressure signal to the control system. When the control system identifies the pressure value and judges that the pressure value exceeds the set value according to the set pressure value, it is judged as a logistics item with a large mass and controls the corresponding electric push rod 16 to rise to push the flip-type sorting table 12 to flip, and the logistics item with a large mass on the upper part slides down along one side obliquely. When the control system identifies that the pressure value does not reach the set value, it is identified as a logistics item with a light mass and makes the corresponding electric push rod 16 contract. As the bottom side of the flip-type sorting table 12 loses the supporting force, the torsion spring 125 in the corresponding flip-type sorting table 12 elastically acts and drives the sorting inclined table 121 to flip in the reverse direction, and the logistics item with a light mass slides down to the other side, completing the sorting of logistics items of different masses.

[0038] First, by placing the intermediate inclined platform 9 between the first conveyor 6 and the second conveyor 7 with a height difference above and below, and cooperating with the connecting plate 19 above the intermediate inclined platform 9, the limiting and blocking of large-volume logistics items are realized, ensuring the downward transportation of small-volume logistics items. At the same time, cooperating with the power air provided by the air supply mechanism 23, after the large-volume logistics item slides down along the top of the intermediate inclined platform 9 and compresses the connecting mechanism 22, the through hole 222 in the connecting mechanism 22 is connected to the inside of the connecting plate 19, so that the fed gas is introduced into the push-type sorting mechanism 24 through the intermediate pipe 28, realizing the pushing of the large-volume logistics item static on the top of the intermediate inclined platform 9, moving from one side of the intermediate inclined platform 9 to the other side, and being smoothly sorted after losing the limitation of the connecting plate 19 and sliding into the third conveyor 8 for sorting and transportation. At the same time, cooperating with the guiding mechanism 11 installed at the front ends of the second conveyor 7 and the third conveyor 8, the corresponding logistics items are guided and slid onto the flipping sorting table 12, cooperating with the pressure sensor 122 on the flipping sorting table 12 to transmit signals to the control system, and judging whether the quality of the logistics item exceeds the set value according to the set signal value in the control system. When it exceeds the set value, the corresponding electric push rod 16 below is controlled to act and push the flipping sorting table 12 to flip, turning the logistics item with a large mass to one side, and when the signal value is lower than the set value, the electric push rod 16 is controlled to contract, and then with the elastic reset of the torsion spring 125 in the flipping sorting table 12, the flipping sorting table 12 is reversely flipped, and the logistics item with a light mass is turned to the other side, completing the sorting of heavy and light logistics items. Similarly, when a set of pressure sensors 122 and electric push rods 16 cooperate with the control system to complete the action process, by changing the layout position and adding the air supply mechanism 23 and the connecting mechanism 22, the automatic sorting of logistics items of different volumes is realized, and then the secondary sorting of heavy and light logistics items is further completed. In fact, when sorting different volumes at the previous stage, there is no need to introduce new sensor components. Under the reasonable layout of the existing sensor positions, double sorting is completed, and the use effect is good.

[0039] In addition, by arranging the intermediate inclined platform 9 between the first conveyor 6 and the second conveyor 7 with a height difference, during the actual sorting process of logistics items of different volumes, the large-volume logistics items to be sorted are static on the top surface of the inclined intermediate inclined platform 9. Thus, when the push rod 244 is pushed to move and push the logistics item under the action of pneumatic thrust, the actual logistics item moves horizontally while being stationary, effectively avoiding the interference of the lateral sorting of the logistics item under the friction and push of the belt in the conveyor, making the pushing of the actual logistics item more stable and reliable, avoiding the deflection of the logistics item during the pushing process, and improving the sorting effect.

[0040] Such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, the number of guiding inclined plates 113 is two. The upper ends of the two guiding inclined plates 113 are close to each other and symmetrically distributed on both sides of the partition plate 13. The two ends of the guiding inclined plate 113 are respectively fixedly connected to the frame plate 1 and the guiding platform 111. The sleeve rod 123 is fixedly connected to the side surface of the sorting inclined platform 121. The sleeve ring 124 is fixedly sleeved on the outer surface of the sleeve rod 123. The sleeve rod 123 and the sleeve ring 124 are rotatably sleeved in the stepped hole 114. The torsion spring 125 is sleeved on the outer surface of the sleeve rod 123. One end of the torsion spring 125 is fixedly connected to the sleeve ring 124, and the other end of the torsion spring 125 is fixedly connected in the stepped hole 114. The number of the bottom frames 15 and the electric push rods 16 is two. The two electric push rods 16 correspond to the two flip-type sorting platforms 12 one by one. The electric push rod 16 is located below the flip-type sorting platform 12.

[0041] During the use process, the guiding inclined plate 113 is used to guide the logistics parts to stably slide onto the flip-type sorting platform 12 for the next reverse sorting. And through the socket connection of the sleeve ring 124 and the stepped hole 114, the rotation stability is maintained. Cooperating with the torsion spring 125, it is maintained horizontally under the push of the bottom electric push rod 16. When the electric push rod 16 moves downward, the elastic reset of the torsion spring 125 is utilized to realize the reverse rotation of the flip-type sorting platform 12.

[0042] As Figure 1 、 Figure 12 、and Figure 13 As shown in the figure, the air supply mechanism 23 includes a fixing plate 231, an air compressor 232 and an air pipe 233. The fixing plate 231 is fixedly connected to the outer side surface of the frame plate 1. The air compressor 232 is fixedly installed on the top surface of the fixing plate 231. The air pipe 233 is fixedly connected between the connecting plate 19 and the air compressor 232. One end of the air pipe 233 is fixedly sleeved inside the top hole 21. The push-type sorting mechanism 24 includes a side seat 241, a distribution frame 242, a sleeve 243, a push rod 244 and a second spring 245. The side seat 241 is fixedly connected to the side surface of the frame plate 1. The distribution frame 242 is fixedly installed on the top surface of the side seat 241. The sleeve 243 is fixedly connected to the side surface of the distribution frame 242. The push rod 244 is movably sleeved inside the sleeve 243. One end of the second spring 245 is fixedly connected in the distribution frame 242, and the other end of the second spring 245 is fixedly connected to the inner end of the push rod 244.

[0043] During the use process, the air supply mechanism 23 is used to provide flowing gas. On the one hand, it is used to blow the logistics parts and the conveying environment. On the other hand, it is used to push the large-volume logistics parts for sorting. By utilizing the elasticity of the second spring 245, it is convenient to discharge the gas during the reset process of the movable plate 221 to realize the reset of the push rod 244.

[0044] As Figure 1 、 Figure 8 、 Figure 9, Figure 10 and Figure 11 As shown, the back side of the connecting plate 19 is fixedly connected to a mounting frame 26, which is located on the outside of the connecting plate 223. One end of the second connecting frame 3 is fixedly connected to an intermediate plate 27, which is located just above the middle of the intermediate ramp 9. The connecting mechanism 22 also includes a first rectangular opening 225, a second rectangular opening 226, a connecting frame 227 and an air outlet 228. The first rectangular opening 225 and the second rectangular opening 226 are respectively opened on the end face and the side face of the movable plate 221, the first rectangular opening 225 and the second rectangular opening 226 are connected, the connecting frame 227 is fixedly connected to the end face of the movable plate 221 and is connected to the first rectangular opening 225, and the air outlet 228 is opened on the bottom face of the connecting frame 227 and is inclined downward toward the first conveyor 6.

[0045] During use, further limiting is achieved by utilizing the intermediate plate 27 to ensure that when sliding along the intermediate inclined platform 9, it can stably slide to the other side of the intermediate inclined platform 9, thereby improving the sorting position accuracy. The connecting mechanism 22 is utilized to realize the connection control in the connecting plate 19. When sorting is required, the movable plate 221 moves to connect the through hole 222 with the side hole 20, thereby allowing the gas to be introduced into the push-type sorting mechanism 24 and realizing sorting push. After the movable plate 221 is reset, as its second rectangular opening 226 is connected with the connecting hole 29, the input gas in the connecting plate 19 enters the first rectangular opening 225, and the purging is completed through the connecting frame 227 in cooperation with the gas outlet 228.

[0046] Second embodiment: Before sorting, start the air supply mechanism 23 first, so that the air compressor 232 in the air supply mechanism 23 passes air into the connecting plate 19 through the air pipe 233, and enters the connecting hole 29 along the top hole 21 in the connecting plate 19, and passes into the first rectangular opening 225 and the second rectangular opening 226 of the movable plate 221, and passes into the connecting frame 227 to be purged downward toward the first conveyor 6. When the large volume pushes the connecting mechanism 22 to move, as the second rectangular opening 226 and the first rectangular opening 225 in the movable plate 221 are offset from the connecting hole 29, the gas in the connecting plate 19 is laterally input into the intermediate tube 28 along the side holes 20 and the connecting hole 222 below.

[0047] First, by reusing the flowing air provided by the air supply mechanism 23, it is started before the logistics sorting. As different types of logistics items are transported on the first conveyor 6, in cooperation with the connecting frame 227 whose top is parallel to the middle inclined platform 9, the air outlet 228 is tilted towards the logistics items transported at the top of the first conveyor 6 for wind blowing and dust removal, realizing the blowing and dust removal of the logistics items during logistics transportation. At the same time, the dust on the top of the first conveyor 6 is blown out to maintain the cleanliness of the logistics items and the first conveyor 6. At the same time, in cooperation with the flowing air formed by the logistics sorting equipment environment, the comfort of the monitoring personnel is improved and the equipment environment temperature is reduced.

[0048] The present invention also provides a sorting method for an automated logistics item sorting device for logistics, including the following sorting steps:

[0049] Step 1: Start the air supply mechanism 23, so that the air compressor 232 in the air supply mechanism 23 passes air into the connecting plate 19 through the air pipe 233, and enters the connecting hole 29 through the top hole 21 in the connecting plate 19, and is introduced into the first rectangular opening 225 and the second rectangular opening 226 of the movable plate 221, and is introduced into the connecting frame 227 and blown downward towards the first conveyor 6, and start the first conveyor 6, the second conveyor 7, and the third conveyor 8;

[0050] Step 2: Logistics items of different large volumes, small volumes, large masses, and small masses are placed on the first conveyor 6 and transported towards the front end of the frame plate 1 through the top belt. When the small-volume logistics items move to the tail of the first conveyor 6, they are pushed onto the middle inclined platform 9 and slide downward along the middle inclined platform 9 to the second conveyor 7 and continue to be transported forward. While the large-volume logistics items contact the connecting plate 19 when sliding downward along the middle inclined platform 9, at the same time, the connecting mechanism 22 sleeved in the middle of the connecting plate 19 is compressed, so that the movable plate 221 in the connecting mechanism 22 moves and the through hole 222 on its side is connected to the side hole 20 in the connecting plate 19. As the movable plate 221 moves, the connecting hole 29 is sealed, and at the same time, the gas passes through the side hole 20 and the through hole 222 in the connecting plate 19 and is input into the middle pipe 28 and introduced into the push-type sorting mechanism 24, so that the push rod 244 in the push-type sorting mechanism 24 moves from one side of the large-volume logistics item and pushes the large-volume logistics item to slide from one side of the middle inclined platform 9 to the other side and automatically slide onto the third conveyor 8 when there is no limit of the connecting plate 19 and is transported away along the third conveyor 8, completing the sorting of the large-volume logistics items;

[0051] Step 3: When the second conveyor 7 and the third conveyor 8 transport small-volume and large-volume logistics items respectively, as the logistics items slide down to the top of the flip-type sorting table 12 through the top of the guiding mechanism 11, at this time, the logistics items are limited and blocked by the baffle 14. At this time, the component force of the logistics items along the sorting inclined table 121 acts on the pressure sensor 122. The pressure sensor 122 transmits the sensed pressure signal to the control system according to the set pressure value. When the control system identifies that the pressure value exceeds the set value, it controls the corresponding electric push rod 16 to rise and push the flip-type sorting table 12 to flip, so that the logistics items with a large mass on the upper part slide down obliquely along one side. When the control system identifies that the pressure value does not reach the set value, it identifies the logistics items with a light mass and causes the corresponding electric push rod 16 to contract. As the flip-type sorting table 12 loses the supporting force at the bottom, the torsion spring 125 in the corresponding flip-type sorting table 12 elastically acts and drives the sorting inclined table 121 to flip in the reverse direction, so that the logistics items with a light mass slide down to the other side, completing the sorting of logistics items with different masses.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

8. The sorting method of the automated logistics part sorting equipment for logistics according to claim 7, characterized in that: It includes the following sorting steps: The first step: Start the air supply mechanism (23), so that the air compressor (232) in the air supply mechanism (23) passes air through the air pipe (233) into the communication plate (19), and enters the communication hole (29) along the top hole (21) in the communication plate (19), and then enters the first rectangular opening (225) and the second rectangular opening (226) of the movable plate (221), and enters the communication frame (227) and blows downward towards the first conveyor (6). At the same time, start the first conveyor (6), the second conveyor (7), and the third conveyor (8). The second step: Logistics items of different large volumes, small volumes, large masses, and small masses are placed on the first conveyor (6) and transported towards the front end of the frame plate (1) through the top belt. When the small-volume logistics items move to the tail of the first conveyor (6), they are pushed onto the intermediate inclined table (9) and slide down along the intermediate inclined table (9) to the second conveyor (7), and continue to be transported forward. When the large-volume logistics items slide down along the intermediate inclined table (9), they contact the communication plate (19), and at the same time compress the communication mechanism (22) sleeved in the middle of the communication plate (19), so that the movable plate (221) in the communication mechanism (22) moves and the through hole (222) on its side is connected to the side hole (20) in the communication plate (19). As the movable plate (221) moves, while the communication hole (29) is sealed, the gas in the communication plate (19) is input into the intermediate pipe (28) through the side hole (20) and the through hole (222), and then enters the push-type sorting mechanism (24), so that the push rod (244) in the push-type sorting mechanism (24) moves from one side of the large-volume logistics item, and pushes the large-volume logistics item to slide from one side of the intermediate inclined table (9) to the other side, and automatically slides onto the third conveyor (8) when there is no limit from the communication plate (19), and is transported away along the third conveyor (8), completing the sorting of the large-volume logistics items. Step 3: When the second conveyor (7) and the third conveyor (8) transport small and large volume logistics items respectively, as the logistics items slide down along the top of the guiding mechanism (11) and fall onto the top of the flip - type sorting table (12), at this time, the logistics items are limited and blocked by the baffle (14). At this time, the component force of the logistics items along the sorting inclined table (121) acts on the pressure sensor (122). The pressure sensor (122) transmits the sensed pressure signal to the control system according to the set pressure value. When the control system identifies that the pressure value exceeds the set value, it controls the corresponding electric push rod (16) to rise and push the flip - type sorting table (12) to flip, so that the logistics items with a large mass on the upper part slide down obliquely along one side. When the control system identifies that the pressure value does not reach the set value, it identifies the logistics items with a light mass and makes the corresponding electric push rod (16) contract. As the flip - type sorting table (12) loses the supporting force at the bottom, the torsion spring (125) in the corresponding flip - type sorting table (12) elastically acts and drives the sorting inclined table (121) to flip in the reverse direction, sliding the logistics items with a light mass to the other side, completing the sorting of logistics items with different masses.
