Description

Technical Field

[0001] The present invention relates to the technical field of turnover sorting, and particularly to a turnover sorting machine for logistics sorting. Background Art

[0002] A turnover sorting machine for logistics sorting is an automated device based on a robotic arm or a turnover mechanism. It combines advanced image recognition technology and precise mechanical structure design to achieve efficient and accurate sorting operations. When the goods reach the turnover area, detection devices such as photoelectric sensors identify the goods information. After the control box receives the sensor signal, it issues an instruction to the turnover mechanism. According to the instruction, the turnover mechanism performs a flipping action to flip the goods by a certain angle, and then pushes them to the designated sorting outlet or collection container.

[0003] For example, the publication number is CN109794418A. This invention relates to the technical field of automated equipment, specifically a turnover sorting machine, which includes a frame body, a code reading device, an unloading device, a reset track, and sorting chutes. A running track is provided on the frame body. The code reading device is arranged above the running track, the unloading device is arranged below the running track, and the reset track is arranged below the running track. A number of turnover trolleys are provided on the running track. A linear motor is also arranged on one side of the running track. The sorting chutes are arranged on both sides of the running track at the unloading device. By adopting a number of unique "one vehicle with two trays" structure turnover trolleys, the sorting efficiency is greatly improved compared with the cross-belt sorting machine with the same configuration, and the equipment cost is greatly reduced; by adopting a tray-type bearing structure, the sorting adaptability is extremely strong, the performance is stable and it is convenient to use; the main line operation is driven by a linear motor, and the unloading and reset mechanisms of the sorting trolleys adopt a pure mechanical structure design, and the energy consumption of the whole set of equipment is very low.

[0004] In the above-mentioned prior art, a lifting rod is arranged at the bottom of each turnover trolley for the turnover trolley to deflect. The turnover trolley is driven by a linear motor to move to the bottom of the code reading structure for code reading work, and finally reaches the sorting position. The turnover is driven by the lifting rod to make the goods slide and be collected. However, this kind of sorting equipment is usually very long, and the number of turnover trolleys used is also very large. Therefore, setting a lifting rod in each turnover trolley for deflection work will increase cost resources. Moreover, among the sorted goods, there are fragile items and electronic devices, which will generate a large impact force when sliding and are likely to cause damage to the items. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the prior art that this kind of sorting equipment is usually very long, and the number of turnover trolleys used is also very large. Therefore, setting a lifting rod in each turnover trolley for deflection work will increase cost resources. Moreover, among the sorted goods, there are fragile items and electronic devices, which will generate a large impact force when sliding and are likely to cause damage to the items.

The turnover component includes a support plate, the support plate is fixed on one side inside the sorting table, and cylinders are fixedly connected to both sides of the top end of the support plate, and a first air rod is arranged at one end of the cylinder.

[0007] As a preferred implementation manner, a pushing deflection head is fixedly connected to the end of the first air rod away from the cylinder, a push rod is rotatably connected to the middle of the pushing deflection head, a push block is fixedly connected to the end of the push rod away from the pushing deflection head, a sliding sleeve is slidably connected to the middle of the push rod, fourth connection heads are rotatably connected to both sides in the radial direction of the sliding sleeve, a support plate is fixedly connected to the bottom end of the fourth connection head, and the bottom end of the support plate is fixedly connected to the support plate. A turning block is arranged at the bottom end of the turnover plate, and a turnover component is arranged at the sorting place. When the turnover plate rotates to the position of the push block, the push block is in contact with the groove. Start the cylinder, the cylinder drives the first air rod to extend, the first air rod pushes the pushing deflection head to slide, the pushing deflection head pushes the push rod to move, the push rod pushes the turning block, and the push rod is limited by the sliding sleeve. Therefore, the push rod gradually changes from an inclined state to a vertical state, and the turnover plate is pushed to deflect with the first connection head as the axis, realizing inclined discharging. Therefore, there is no need to set a lifting rod at the bottom of each turnover plate to drive the deflection block to incline, reducing resources.

[0008] As a preferred implementation manner, a support convex block is fixedly connected to the middle of the top end of the electric slider, a first connection head is rotatably connected to the top end of the support convex block, a turnover plate is fixedly connected to the top end of the first connection head, baffles are fixedly connected to both sides inside the turnover plate, a turning block is fixedly connected to one side of the bottom end of the turnover plate, and a groove is opened at the bottom end of the turning block, and the groove is slidably connected to the push block. A turning block is arranged at the bottom end of the turnover plate, and a turnover component is arranged at the sorting place. The goods are placed on the turnover plate during work and are located in the middle of the baffle. Then, it is conveyed by the electric slider, and the reading is carried out through the bottom of the code reading device. After the reading is completed, it is conveyed to the support plate, and the turnover plate rotates to the position of the push block.

[0009] As a preferred embodiment, third connectors are fixedly connected to both sides of the bottom end of the turnover plate and located at both sides of the first connector. A spring tube is rotatably connected to the middle of the third connector. One end of the spring tube far away from the third connector is fixedly connected to a second connector. The bottom end of the second connector is fixedly connected to the top end of the electric slider. After the discharging is completed, the first air rod drives the push rod to retract, and the sliding sleeve gradually tilts. Then, with the applied force decreasing, the turnover plate returns to the horizontal position by the pulling force and the pushing force of the spring tube. Subsequently, the electric slider continues to move, enabling the next turnover plate for discharging to repeat the operation.

[0010] As a preferred embodiment, the discharging limiting assembly includes a support frame which is fixed on one side of the top end of the support plate close to the air cylinder. Guide plates are fixedly connected to both sides of the top end of the support frame. The support frame is used for supporting the guide plates, and the guide plates are used for supporting the sliding rod and the connecting block, facilitating the fixation of the limiting plate to assist in discharging.

[0011] As a preferred embodiment, a guide chute is formed in the middle of the guide plate. A sliding rod is slidably connected to the inside of the guide chute. One end of the sliding rod close to the support frame is fixedly connected to a connecting rod. The bottom end of the connecting rod is fixedly connected to a first fixing sleeve which is fixedly connected to the first air rod. When the first air rod extends, it drives the first fixing sleeve to move. The first fixing sleeve drives the connecting rod to move, and the connecting rod drives the sliding rod to slide along the track of the guide chute.

[0012] As a preferred embodiment, a connecting block is fixedly connected to the end of the sliding rod far away from the support frame. The connecting block is slidably connected to the guide chute. A second air rod is fixedly connected to the bottom end of the connecting block. The bottom end of the second air rod is rotatably connected to a fifth connector. The bottom end of the fifth connector is fixedly connected to a fixed limiting plate. A telescopic limiting plate is slidably connected to the bottom end of the fixed limiting plate. When the second air rod is started, it drives the fifth connector to move downward. The fifth connector drives the fixed limiting plate to move. The fixed limiting plate drives the telescopic limiting plate and the fixed rod to move. The telescopic limiting plate moves above the goods and gently contacts the goods. The sliding rod drives the connecting block to move. The connecting block drives the second air rod to move. The second air rod drives the fixed limiting plate to move, and the moving direction of the fixed limiting plate is consistent with the inertial sliding direction of the goods when the turnover plate tilts. Therefore, the slow movement can be realized through the friction between the goods and the telescopic limiting plate and the movement of the fixed limiting plate, thus avoiding the collision and damage of the items caused by the too-fast sliding of the goods.

[0013] As a preferred embodiment, a first spring is fixedly connected at equal intervals at the top inside the fixed limit plate, the top of the first spring is fixedly connected to the fixed limit plate, a second fixed sleeve is fixedly connected to the top of the second air rod at the fifth connection head, a second spring is fixedly connected to one side of the second fixed sleeve, and the end of the second spring away from the second fixed sleeve is fixedly connected to the fixed limit plate. When the fixed rod drives the fixed limit plate to deflect, the second spring is stretched. When the second air rod retracts, the fixed rod loses the applied force, causing the second spring to start pulling back and driving the fixed limit plate back to its original position. The first spring can reduce the applied pressure when the telescopic limit plate contacts the goods, preventing the goods from being unable to slide due to excessive pressure.

[0014] As a preferred embodiment, the auxiliary deflection assembly includes a fixed rod, the fixed rod is fixed in the middle of both sides of the fixed limit plate, a fixed cylinder is fixedly connected to the bottom end of the fixed rod, a telescopic rod is slidably connected to the bottom end of the fixed cylinder, the telescopic rod penetrates through the fixed cylinder, the fixed rod drives the fixed cylinder to move down, the fixed cylinder drives the telescopic rod to move down, the telescopic rod drives the deflection block to move down, and finally contacts the inside of the turnover plate. As the telescopic limit plate contacts the goods, the telescopic rod compresses the third spring, enabling the deflection block to contact the turnover plate when adapting to goods of different heights.

[0015] As a preferred embodiment, a third spring is fixedly connected inside the fixed cylinder, the bottom end of the third spring is fixedly connected to the top end of the telescopic rod, the bottom end of the telescopic rod is fixedly connected to a deflection block. When the turnover plate deflects, the force applied by the deflection block to the turnover plate causes the deflection block to deflect with the deflection of the turnover plate. The deflection block drives the fixed cylinder to deflect, the fixed cylinder drives the fixed rod to deflect, and the fixed rod drives the fixed limit plate to deflect, enabling the fixed limit plate to deflect synchronously with the turnover plate, facilitating the telescopic limit plate to be at the same angle as the goods.

[0016] The beneficial effects of the present invention are as follows:

[0017] In the present invention, a turning block is provided at the bottom end of the turnover plate, and a turning assembly is provided at the sorting location. When the turnover plate rotates to the push block, the push block is attached to the groove, the air cylinder is started, the air cylinder drives the first air rod to extend, the first air rod pushes the deflection head to slide, the pushed deflection head pushes the push rod to move, the push rod pushes the turning block, and the push rod is limited by the sliding sleeve. Therefore, the push rod gradually changes from an inclined state to a vertical state and drives the turnover plate to deflect with the first connection head as the axis, realizing inclined discharging. Therefore, there is no need to provide a lifting rod at the bottom end of each turnover plate to drive the deflection block to incline, reducing resources.

[0018] In the present invention, when the second air rod is activated, the second air rod drives the fifth connector to move downward. The fifth connector drives the fixed limit plate to move, and the fixed limit plate drives the telescopic limit plate and the fixed rod to move. The telescopic limit plate moves above the goods and gently contacts the goods. When the first air rod extends, it drives the first fixed sleeve to move. The first fixed sleeve drives the connecting rod to move, and the connecting rod drives the sliding rod to slide along the trajectory of the guiding chute. The sliding rod drives the connecting block to move, and the connecting block drives the second air rod to move. The second air rod drives the fixed limit plate to move, and the moving direction of the fixed limit plate is the same as the inertial sliding direction of the goods when the turnover plate tilts. Therefore, slow movement can be achieved through the friction between the goods and the telescopic limit plate and the movement of the fixed limit plate, thereby avoiding the collision and damage of items caused by the too-fast sliding of the goods.

[0019] In the present invention, the fixed rod drives the fixed cylinder to move downward, the fixed cylinder drives the telescopic rod to move downward, and the telescopic rod drives the deflection block to move downward until it finally contacts the inside of the turnover plate. As the telescopic limit plate contacts the goods, the telescopic rod compresses the third spring, enabling the deflection block to contact the turnover plate when adapting to goods of different heights. Then, when the turnover plate deflects, the force exerted by the deflection block on the turnover plate causes the deflection block to deflect along with the deflection of the turnover plate. The deflection block drives the fixed cylinder to deflect, the fixed cylinder drives the fixed rod to deflect, and the fixed rod drives the fixed limit plate to deflect, making the fixed limit plate deflect synchronously with the turnover plate, facilitating the same angle between the telescopic limit plate and the goods.

[0032] As Figure 1 - Figure 8As shown, at one end of the first air rod 412 away from the air cylinder 411, a pushing deflection head 413 is fixedly connected. At the middle of the pushing deflection head 413, a push rod 414 is rotatably connected. At one end of the push rod 414 away from the pushing deflection head 413, a push block 415 is fixedly connected. At the middle of the push rod 414, a sliding sleeve 416 is slidably connected. On both radial sides of the sliding sleeve 416, a fourth connecting head 417 is rotatably connected. At the bottom end of the fourth connecting head 417, a support plate 418 is fixedly connected. The bottom end of the support plate 418 is fixedly connected to the support plate 41. In the middle of the top end of the electric slider 31, a support convex block 35 is fixedly connected. At the top end of the support convex block 35, a first connecting head 34 is rotatably connected. At the top end of the first connecting head 34, a turnover plate 32 is fixedly connected. On both sides inside the turnover plate 32, baffles 33 are fixedly connected. At one side of the bottom end of the turnover plate 32, a turning block 39 is fixedly connected. At the bottom end of the turning block 39, a groove 310 is formed. The groove 310 is slidably connected to the push block 415.

[0033] In this embodiment, a turning block 39 is arranged at the bottom end of the turnover plate 32, and a turning component is arranged at the sorting place. The worker puts the goods on the turnover plate 32 and at the middle of the baffle 33. Then, it is conveyed by the electric slider 31. The conveying passes through the bottom end of the code reading device 2 for code reading. After the code reading is completed, it is conveyed to the support plate 41. When the turnover plate 32 rotates to the push block 415, the push block 415 abuts against the groove 310. The air cylinder 411 is started. The air cylinder 411 drives the first air rod 412 to extend. The first air rod 412 pushes the deflection head 413 to slide. The pushing deflection head 413 pushes the push rod 414 to move. The push rod 414 pushes the turning block 39. And the push rod 414 is limited by the sliding sleeve 416. Therefore, the push rod 414 gradually changes from an inclined state to a vertical state, and drives the turnover plate 32 to deflect with the first connecting head 34 as the axis, realizing inclined unloading. Therefore, there is no need to arrange a lifting rod at the bottom end of each turnover plate 32 to drive the deflection block 434 to incline, reducing resources. After the unloading is completed, the first air rod 412 drives the push rod 414 to retract, and the sliding sleeve 416 gradually inclines. And the turnover plate 32 is horizontal between the pulling force and the pushing force of the spring tube 37 as the applied force decreases. Then, the electric slider 31 continues to move, so that the next turnover plate 32 for unloading repeats the operation.

[0034] As Figure 1 - Figure 8As shown in the figure, a guiding chute 422 is provided in the middle of the guiding plate 421. A sliding rod 425 is slidably connected inside the guiding chute 422. One end of the sliding rod 425 close to the support frame 42 is fixedly connected with a connecting rod 424. The bottom end of the connecting rod 424 is fixedly connected with a first fixing sleeve 423. The first fixing sleeve 423 is fixedly connected with the first air rod 412. One end of the sliding rod 425 away from the support frame 42 is fixedly connected with a connecting block 426. The connecting block 426 is slidably connected with the guiding chute 422. The bottom end of the connecting block 426 is fixedly connected with a second air rod 427. The bottom end of the second air rod 427 is rotatably connected with a fifth connecting head 428. The bottom end of the fifth connecting head 428 is fixedly connected with a fixed limiting plate 429. The bottom end of the fixed limiting plate 429 is slidably connected with a telescopic limiting plate 4210. At the top end inside the fixed limiting plate 429, a first spring 4211 is fixedly connected at equal intervals. The top end of the first spring 4211 is fixedly connected with the fixed limiting plate 429. At the top end of the second air rod 427 where it is located at the fifth connecting head 428, a second fixing sleeve 4212 is fixedly connected. One side of the second fixing sleeve 4212 is fixedly connected with a second spring 4213. One end of the second spring 4213 away from the second fixing sleeve 4212 is fixedly connected with the fixed limiting plate 429.

[0035] In this embodiment, when the second air rod 427 is started, the second air rod 427 drives the fifth connecting head 428 to move downward. The fifth connecting head 428 drives the fixed limiting plate 429 to move. The fixed limiting plate 429 drives the telescopic limiting plate 4210 and the fixed rod 43 to move. The telescopic limiting plate 4210 moves above the goods and gently contacts the goods. And the first air rod 412 extends to drive the first fixing sleeve 423 to move. The first fixing sleeve 423 drives the connecting rod 424 to move. The connecting rod 424 drives the sliding rod 425 to slide along the track of the guiding chute 422. The sliding rod 425 drives the connecting block 426 to move. The connecting block 426 drives the second air rod 427 to move. The second air rod 427 drives the fixed limiting plate 429 to move. And the moving direction of the fixed limiting plate 429 is consistent with the inertial sliding direction of the goods when the turnover plate 32 is tilted. Therefore, slow movement can be realized through the friction between the goods and the telescopic limiting plate 4210 and the movement of the fixed limiting plate 429, so as to avoid the collision and damage of items caused by the too-fast sliding down of the goods.

[0036] As Figure 1 - Figure 8 As shown in the figure, the auxiliary deflection assembly includes a fixed rod 43. The fixed rod 43 is fixed in the middle of both sides of the fixed limiting plate 429. The bottom end of the fixed rod 43 is fixedly connected with a fixed cylinder 431. The bottom end of the fixed cylinder 431 is slidably connected with a telescopic rod 432. The telescopic rod 432 penetrates through the fixed cylinder 431. Inside the fixed cylinder 431, a third spring 433 is fixedly connected. The bottom end of the third spring 433 is fixedly connected with the top end of the telescopic rod 432. The bottom end of the telescopic rod 432 is fixedly connected with a deflection block 434.

[0037] In this embodiment, the fixed rod 43 drives the fixed cylinder 431 to move downward, the fixed cylinder 431 drives the telescopic rod 432 to move downward, the telescopic rod 432 drives the deflection block 434 to move downward, and finally it contacts the inside of the turnover plate 32. As the telescopic limiting plate 4210 contacts the goods, the telescopic rod 432 compresses the third spring 433, so that the deflection block 434 contacts the turnover plate 32 when adapting to goods of different heights. Then, when the turnover plate 32 deflects, the force exerted by the deflection block 434 on the turnover plate 32 causes the deflection block 434 to deflect along with the deflection of the turnover plate 32. The deflection block 434 drives the fixed cylinder 431 to deflect, the fixed cylinder 431 drives the fixed rod 43 to deflect, and the fixed rod 43 drives the fixed limiting plate 429 to deflect, so that the fixed limiting plate 429 deflects synchronously with the turnover plate 32, facilitating the telescopic limiting plate 4210 to be at the same angle as the goods.

[0038] Working principle: First, a turning block 39 is arranged at the bottom of the turnover plate 32, and a turning component is arranged at the sorting position. During operation, goods are placed on the turnover plate 32 and located in the middle of the baffle 33. Then, it is conveyed by the electric slider 31. The conveying passes through the bottom of the code reading device 2 for code reading. After the code reading is completed, it is conveyed to the support plate 41. When the turnover plate 32 rotates to the push block 415, the push block 415 is in contact with the groove 310. The second air rod 427 is started, and the second air rod 427 drives the fifth connector 428 to move downward. The fifth connector 428 drives the fixed limit plate 429 to move. The fixed limit plate 429 drives the telescopic limit plate 4210 and the fixed rod 43 to move. The telescopic limit plate 4210 moves above the goods and gently contacts the goods. The fixed rod 43 drives the fixed cylinder 431 to move downward. The fixed cylinder 431 drives the telescopic rod 432 to move downward. The telescopic rod 432 drives the deflection block 434 to move downward and finally contacts the inside of the turnover plate 32. As the telescopic limit plate 4210 contacts the goods, the telescopic rod 432 compresses the third spring 433, so that the deflection block 434 contacts the turnover plate 32 when adapting to goods of different heights. The cylinder 411 is started, and the cylinder 411 drives the first air rod 412 to extend. The first air rod 412 pushes the deflection head 413 and the first fixed sleeve 423 to slide. The pushing deflection head 413 pushes the push rod 414 to move. The push rod 414 pushes the turning block 39. The push rod 414 is limited by the sliding sleeve 416. Therefore, the push rod 414 gradually changes from an inclined state to a vertical state and pushes the turnover plate 32 to deflect around the first connector 34 to achieve inclined discharging. Therefore, there is no need to arrange a lifting rod at the bottom of each turnover plate 32 to drive the deflection block 434 to incline, reducing resources. When the turnover plate 32 deflects, the force exerted by the deflection block 434 on the turnover plate 32 causes the deflection block 434 to deflect along with the deflection of the turnover plate 32. The deflection block 434 drives the fixed cylinder 431 to deflect. The fixed cylinder 431 drives the fixed rod 43 to deflect. The fixed rod 43 drives the fixed limit plate 429 to deflect, so that the fixed limit plate 429 deflects synchronously with the turnover plate 32, facilitating the telescopic limit plate 4210 to be at the same angle as the goods. The extension of the first air rod 412 drives the first fixed sleeve 423 to move. The first fixed sleeve 423 drives the connecting rod 424 to move. The connecting rod 424 drives the sliding rod 425 to slide along the track of the guiding chute 422. The sliding rod 425 drives the connecting block 426 to move. The connecting block 426 drives the second air rod 427 to move. The second air rod 427 drives the fixed limit plate 429 to move, and the moving direction of the fixed limit plate 429 is the same as the inertial sliding direction of the goods when the turnover plate 32 inclines. Therefore, slow movement can be realized through the friction between the goods and the telescopic limit plate 4210 and the movement of the fixed limit plate 429, thus avoiding the collision and damage of items caused by the too-fast sliding of the goods.
