Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, and specifically refers to a material sorting mechanism. Background Technology

[0002] In industrial production lines, round tubes are a common type of workpiece, typically requiring multiple steps such as conveying, gripping, cutting, and placement. Existing automated production lines usually use conveyor belts to transport workpieces. However, some workstations have different functions, locations, and elevations, necessitating transfer between different workstations. Traditionally, this relies on manual operation, where workers manually move the round tubes from one workstation to the next. This method is labor-intensive, requiring workers to repeatedly bend over and lift the tubes, and is inefficient. The speed of manual handling is limited by the worker's physical strength, making it difficult to match the pace of automated production lines. Furthermore, slippage and collisions can occur during manual handling. Therefore, an automated material handling mechanism is needed to replace manual material handling, enabling the automated transport of workpieces to the next workstation. Summary of the Invention

[0003] The purpose of this invention is to provide a simple and automated material feeding mechanism to replace manual material feeding, enabling the workpiece to be automatically transported to the next workstation.

[0004] The purpose of this utility model is achieved as follows:

[0005] A material sorting mechanism includes a material sorting device located on one side of a transport station. The material sorting device includes a material sorting base, rotating seats at both ends of the material sorting base, and a loading base. A material sorting plate is rotatably mounted on the rotating seat, driving the material sorting plate to rotate around the rotating seat. The material sorting plate can be raised or lowered relative to the material sorting base. The loading base is equipped with a transmission device and a driving cylinder. The transmission device includes a transmission rod rotatably connected to the loading base, a material sorting crank rod mounted on the transmission rod, and a first transmission part and a second transmission part mounted on the material sorting crank rod. The first and second transmission parts protrude from the material sorting crank rod and extend towards the rotating seat, and can rotate synchronously with the transmission rod. The first transmission part and the second transmission part... The two transmission parts form an angle between them. The second transmission part is connected to the material feeding plate. The drive cylinder is equipped with a retractable piston rod, which is connected to the first transmission part. When the piston rod drives the first transmission part to rotate the material feeding crank, the transmission rod rotates with the material feeding crank, causing the second transmission part to rotate synchronously and drive the material feeding plate to rise. At this time, the material feeding plate moves upward synchronously. The front end of the material feeding plate is equipped with a material stop. When the workpiece on the transport station moves towards the material feeding and sorting device, the end of the workpiece can abut against the material stop and restrict the workpiece from continuing to roll and be transported. When the piston rod retracts and resets, the workpiece is released from the restriction and is rolled and transported to the upper surface of the material feeding plate and then to the next station.

[0006] Furthermore, the piston rod end is connected to a hydraulic cylinder joint, the first transmission part is provided with a first connecting hole, the first connecting hole is provided with a first connecting shaft, and the hydraulic cylinder joint is connected to the first connecting shaft.

[0007] Furthermore, the feeding plate is provided with a feeding connecting plate, the second transmission part is provided with a second connecting hole, the second connecting hole is provided with a second connecting shaft, one end of the feeding connecting plate is connected to the second connecting shaft, and the other end is connected to the feeding plate.

[0008] Furthermore, several reinforcing ribs are provided between the first and second transmission parts and the feeding crank.

[0009] Furthermore, the number of the material sorting devices is two, and the material sorting devices can be respectively located at both ends of the transmission rod.

[0010] Furthermore, the rotating seat is provided with a rotating shaft, and one end of the feeding plate is connected to the rotating seat through the rotating shaft.

[0011] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0012] This utility model relates to an automated material handling mechanism. Compared to existing manual handling methods, this application can improve work efficiency, reduce labor intensity, maintain production rhythm, and prevent injury or accidents to workers when workpieces come into contact with them. The mechanism uses a piston rod on a drive cylinder to raise or lower a material handling plate. One end of the material handling plate rotates with a rotating base. When the drive cylinder extends the piston rod, the material handling plate is pushed by the piston rod and rotates around the rotating base. The transmission device consists of a transmission rod, a material handling crank, a first transmission part, and a second transmission part. The first and second transmission parts protrude from the material handling crank and extend towards the rotating base. It can rotate synchronously with the transmission rod. When the first rotating part drives the material-feeding crank to rotate synchronously, the second rotating part also rotates synchronously with the material-feeding crank, realizing multi-stage linkage. Since both the first and second rotating parts face the rotating seat, when the piston rod extends, the apex of the second rotating part will rise with the rotation process, thereby raising the material-feeding plate. By forming a lever structure, the extension and retraction of the piston rod can be accurately converted into the lifting and lowering height of the material-feeding plate through the crank angle. It is suitable for workstations with strict requirements for workpiece position. The drive cylinder acts directly on the first transmission part through the piston rod, using the crank principle to convert linear motion into rotational motion. The second transmission unit then drives the lifting plate to rise and fall, resulting in a simple and efficient power transmission path with low energy loss. This ensures strict synchronization between the piston rod's movement and the lifting of the lifting plate, avoiding slippage or delay issues that may occur with traditional chain / belt drives. Furthermore, its placement at both ends of the lifting seat saves more longitudinal space compared to parallel linkage mechanisms, making it particularly suitable for side installation in narrow transport stations. This invention uses a lifting method to smoothly lift the lifting plate from the bottom of the workpiece, avoiding surface scratches that may be caused by traditional grippers. It is especially suitable for handling sheet metal and box-shaped workpieces. This invention also prevents large batches of workpieces from being stacked excessively and becoming impossible to sort. When the workpiece rolls towards the material sorting device, it can reach the stop section, at which point the workpiece can no longer move. When the piston rod retracts, the first transmission part drives the material sorting crank to rotate, causing the second transmission part to rotate counterclockwise from a high point to a low point. At this time, the material sorting plate can descend, and the stop section can no longer block the workpiece. The workpiece rolls to the upper surface of the material sorting plate due to inertia. At this time, the piston rod extends again, causing the first transmission part to drive the material sorting crank to rotate, causing the second transmission part to rotate clockwise from a low point to a high point. The workpiece can continue to roll to the next transport position. At this time, the raised material sorting plate can restrict the rolling of the next workpiece through the stop section, so that each workpiece is transported in an orderly queue.

Detailed Implementation

[0029] The present invention will be further described below with reference to specific embodiments:

[0030] A material sorting mechanism includes a material sorting device 1 located on one side of a transport station 20. The transport station 20 includes a feeding belt 21 and a material sorting belt 22. The feeding belt 21 is inclined relative to the material sorting belt 22 and can roll and transport workpieces placed at the end of the feeding belt 21 towards the material sorting belt 22. The material sorting device 1 includes a material sorting seat 2, a rotating seat 3 located at both ends of the material sorting seat 2, and a loading seat 4. A material sorting plate 5 is rotatably mounted on the rotating seat 3, driving the material sorting plate 5 to rotate around the rotating seat 3. The material sorting plate 5 can be raised or lowered relative to the material sorting seat 2. The loading seat 4 is equipped with a transmission device 6 and a driving cylinder 7. The transmission device 6 includes a transmission rod 9 rotatably connected to the loading seat 4, a material sorting crank 23 mounted on the transmission rod 9, a first transmission part 10 and a second transmission part 11 mounted on the material sorting crank 23, and the first transmission part 10 and the second transmission part 11 protruding from the material sorting seat 4. The material guide rod 23 extends towards the rotating seat 3 and can rotate synchronously with the transmission rod 9. An angle is formed between the first transmission part 10 and the second transmission part 11. The second transmission part 11 is connected to the material guide plate 5. The drive cylinder 7 is provided with a telescopic piston rod 8. The piston rod 8 is connected to the first transmission part 10. When the piston rod 8 drives the first transmission part 10 to rotate the material guide rod 23, the transmission rod 9 rotates with the material guide rod 23, causing the second transmission part 11 to rotate synchronously and drive the material guide plate 5 to rise. At this time, the material guide plate 5 moves upward synchronously. The front end of the material guide plate 5 is provided with a stop part 26. When the workpiece on the transport station 20 moves towards the material guide sorting device 1, the end of the workpiece can abut against the stop part 26 and restrict the workpiece from continuing to roll and be conveyed. When the piston rod 8 retracts and resets, the workpiece is released from restriction and is rolled and conveyed to the upper surface of the material guide plate 5 and then to the next station.

[0031] This utility model is an automated material feeding mechanism. Compared with existing manual handling, this application can improve work efficiency, reduce the labor intensity of workers, maintain production rhythm, and avoid injury or accidents to workers when workpieces come into contact with them. The piston rod 8 on the drive cylinder 7 drives the feeding plate 5 to rise or fall. One end of the feeding plate 5 rotates with the rotating seat 3. When the drive cylinder 7 drives the piston rod 8 to extend, the feeding plate 5 is pushed by the piston rod 8 and thus rotates around the rotating seat 3. The transmission device 6 consists of a transmission rod 9, a feeding crank 23, a first transmission part 10, and a second transmission part 11. The first transmission part 10 and the second transmission part 11 protrude from the feeding crank 23 and rotate towards the center. The seat 3 extends in the direction of rotation and can rotate synchronously with the transmission rod 9. When the first rotating part drives the material-feeding crank 23 to rotate synchronously, the second rotating part also rotates synchronously with the material-feeding crank 23, realizing multi-level linkage. Since both the first and second rotating parts face the rotating seat 3, when the piston rod 8 extends, the apex of the second rotating part will rise with the rotation process, thereby raising the material-feeding plate 5. By forming a lever structure, the extension and retraction of the piston rod 8 can be accurately converted into the lifting and lowering height of the material-feeding plate 5 through the crank angle, which is suitable for workstations with strict requirements for workpiece position. The drive cylinder 7 acts directly on the first transmission part 10 through the piston rod 8, using the crank principle to convert linear motion into linear motion. The rotational motion, via the second transmission unit 11, drives the lifting plate 5 to rise and fall. This power transmission path is simple and efficient, with low energy loss, ensuring strict synchronization between the piston rod 8 and the lifting of the lifting plate 5. This avoids slippage or delay issues that may occur with traditional chain / belt drives. Furthermore, its placement at both ends of the lifting seat 2 saves longitudinal space compared to parallel linkage mechanisms, making it particularly suitable for side installation in narrow transport stations. This invention uses a lifting method to smoothly lift the lifting plate 5 from the bottom of the workpiece, avoiding surface scratches that may be caused by traditional grippers. It is especially suitable for handling sheet metal and box-shaped workpieces. This invention also prevents large batches of workpieces from being stacked excessively and becoming impossible to sort. When workpieces are being lifted and sorted... When the workpiece rolls in direction 1, it can reach the stop part 26, at which point the workpiece can no longer move. When the piston rod 8 retracts, the first transmission part 10 drives the material-pushing crank 23 to rotate, causing the second transmission part 11 to rotate counterclockwise from a high point to a low point. At this time, the material-pushing plate 5 can descend, and the stop part 26 can no longer block the workpiece. The workpiece rolls to the upper surface of the material-pushing plate 5 due to inertia. At this time, the piston rod 8 extends again, causing the first transmission part 10 to drive the material-pushing crank 23 to rotate, causing the second transmission part 11 to rotate clockwise from a low point to a high point. The workpiece can continue to roll to the next transport position. At this time, the raised material-pushing plate 5 can restrict the rolling of the next workpiece through the stop part 26, so that each workpiece is transported in an orderly queue.

[0032] Preferably, the piston rod 8 is connected to a hydraulic cylinder joint 12 at its end, and a first connecting hole 13 is provided on the first transmission part 10. A first connecting shaft 14 is provided in the first connecting hole 13. The hydraulic cylinder joint 12 is connected to the first connecting shaft 14. During the extension and retraction process, the piston rod 8 may have slight radial swing or installation misalignment. The hydraulic cylinder joint 12 can automatically adjust the angle to avoid rigid interference between the piston rod 8 and the first transmission part 10, reduce structural deformation or seal wear, and improve transmission smoothness.

[0033] Preferably, the material feeding plate 5 is provided with a material feeding connecting plate 15, and the second transmission part 11 is provided with a second connecting hole 16. A second connecting shaft 17 is provided in the second connecting hole 16. One end of the material feeding connecting plate 15 is connected to the second connecting shaft 17, and the other end is connected to the material feeding plate 5. As an intermediate connecting member, the material feeding connecting plate 15 can absorb some of the vibration and impact during the transmission process, avoid direct rigid contact between the material feeding plate 5 and the transmission rod 9, make the lifting and lowering of the workpiece more stable, optimize the force distribution, and extend the service life.

[0034] Preferably, a number of reinforcing ribs 18 are provided between the first transmission part 10 and the second transmission part 11 and the feed crank 23 to improve the structural strength and rigidity, avoid bending deformation, increase torsional resistance, and disperse stress concentration.

[0035] Preferably, there are two material sorting devices 1, which can be respectively located at both ends of the transmission rod 9. The transport station 20 is located between the two material sorting devices 1. The transport station 20 also includes a transport base 24. The feeding belt 21 and the material sorting belt 22 are located on the upper surface of the transport base 24. The transport base 24 has a vertical oblong hole 25. The transmission rod 9 passes through the oblong hole 25. A baffle is also provided at one end of the transport base 24. The baffle extends vertically upward and is located at the end of the material sorting belt 22. The baffle part 26 is located on one side between the feeding belt 21 and the material sorting belt 22, thereby restricting the rolling and stacking of workpieces, speeding up the work efficiency, and enabling the production line to simultaneously sort multiple workpieces at one time. The operation of the two material sorting devices 1 is realized through one transmission rod 9. Figure 13 As shown, the circular part represents the workpiece being blocked by the stop part 26. At this time, the workpiece is on the inclined feed belt 21 and still has the inertia of rolling downwards. When the drive cylinder 7 drives the movement, the workpiece rolls towards the feeding belt 22 with inertia. At this time, the workpiece located on the feeding belt 22 can be removed by other automated tools such as a transport trolley. During the removal process, the drive cylinder 7 drives the feeding plate 5 to lift up and restrict the workpiece being rolled and transported on the next feed belt 21.

[0036] Preferably, the rotating seat 3 is provided with a rotating shaft 19, and one end of the feeding plate 5 is connected to the rotating seat 3 through the rotating shaft 19.
