Description

Technical Field

[0001] This invention relates to the field of round steel cutting and stacking technology, specifically to a round steel cutting and stacking device and its usage method. Background Technology

[0002] Round steel refers to solid long steel bars with a circular cross-section. Round steel is divided into three types: hot-rolled, forged, and cold-drawn. It is commonly used as reinforcing bars, bolts, and various mechanical parts, as well as blanks for manufacturing mechanical parts and seamless steel pipes. When producing or further processing round steel, a large number of round steel bars need to be fed onto a conveyor belt in sequence for transportation.

[0003] In the prior art, patent number CN116605664A, entitled "A Round Steel Cutting and Stacking Device and Method Thereof," relates to the field of round steel cutting technology. It solves the problem of time-consuming and labor-intensive round steel cutting, stacking, and transfer, saving manpower and resources. The device includes a conveying mechanism and a storage trolley. The storage trolley is equipped with a storage tray, and its height is lower than that of the conveying mechanism. The trolley is connected to the discharge end of the conveying mechanism via an inclined transition plate. The conveying mechanism includes a conveying unit for conveying round steel. Two rows of opposing push blocks are fixed along the length of the conveying unit, with each row containing several arc-shaped push blocks whose shape matches the round steel. The bottom of the storage tray's internal space is inclined, and baffles are fixed on both sides of the transition plate. The width of both the transition plate and the storage tray is the same as the length of the round steel.

[0004] However, existing palletizing devices cannot stack round steel bars evenly. When there are gaps between the round steel bars, it is difficult to remove them. Summary of the Invention

[0005] The purpose of this invention is to provide a round steel bar unloading and stacking device and its usage method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a round steel bar unloading and stacking device, comprising:

[0007] The lifting rod has a movable frame fixed to its bottom, an arc-shaped plate fixed to its bottom, a swing shaft at the end of the arc-shaped plate, a swing plate on the surface of the swing shaft, an electromagnetic plate fixed to the bottom of the swing plate, a groove on the surface of the swing plate, a rubber plate on the surface of the groove, a rubber strip at the end of the rubber plate, an L-shaped plate on the surface of the movable frame, a motor at the end of the L-shaped plate, a gear at the end of the motor, a connecting block fixed to the end of the L-shaped plate, and a transverse sliding plate inside the connecting block.

[0008] Preferably, the lifting rod can drive the movable frame to move. A support seat is placed at the bottom of the movable frame. A side plate is fixed on the surface of the support seat. A slot is opened on the surface of the side plate. Through slots are opened on the surfaces of the lifting rod and the movable frame. A round steel is placed at the bottom of the movable frame. An electromagnetic plate can attract the round steel to the surface. Two sets of swing plates are provided at the bottom of the movable frame. Limit plates are fixed on both sides of the bottom of the swing plates.

[0009] Preferably, the surface of the movable frame is provided with a swing groove, and a rotating shaft is provided in the swing groove. The rotating shaft can rotate in the swing groove and is fixed to the end of the L-shaped plate. The L-shaped plate can swing along the rotating shaft. The surface of the movable frame is fixed with a first extension block and a second extension block. A pushing device is provided inside the first extension block. Two sets of positioning plates are inserted into the surface of the first extension block. The positioning plates can extend and retract inside the first extension block. The pushing device is connected to the end of the positioning plate and pushes the positioning plate to move.

[0010] Preferably, the surface of the second extension block is provided with an insertion groove, and the positioning plate can be inserted into the insertion groove after it moves. A connecting block is fixed at the other end of the L-shaped plate, and a motor is fixed on the surface of the L-shaped plate. The motor swings with the L-shaped plate. A gear is provided at the end of the motor, and the motor can drive the gear to rotate. A transverse plate is inserted into the inside of the connecting block, and the transverse plate can move inside the connecting block. The surface of the transverse plate is provided with a tooth groove, and the tooth groove meshes with the teeth on the surface of the gear. After the gear rotates, it can drive the transverse plate to move.

[0011] Preferably, one end of the transverse plate is fixed with a top holding plate, the top holding plates at the ends of the two sets of transverse plates are close to each other, the top holding plates move with the transverse plates, the tooth groove is located at the top of the transverse plate, and multiple sets of tooth grooves are provided.

[0012] Preferably, a limit strip is fixed to one end of the swing plate, and a swing shaft is provided at the other end of the swing plate. An arc plate is fixed to the bottom of the moving frame. The swing plate is hinged to the end of the arc plate through the swing shaft. The swing plate can swing along the swing shaft. After the swing plate is tilted, the round steel can roll on the surface of the electromagnetic plate. After the round steel rolls on the surface of the electromagnetic plate, it presses against the surface of the rubber strip and the rubber plate, so that the rubber strip and the rubber plate are retracted into the inside of the groove.

[0013] Preferably, a cylinder is fixed in the through groove, and a piston rod is provided at the end of the cylinder. The cylinder can drive the piston rod to move up and down. A dispersing rod is fixed at the other end of the piston rod. The dispersing rod moves up and down with the piston rod. A plug-in rod is fixed at the other end of the dispersing rod. A horizontal groove is opened on the surface of the swing plate. An inner groove is opened inside the horizontal groove. The end of the dispersing rod is located in the horizontal groove. The two sides of the plug-in rod are inserted into the inner groove.

[0014] Preferably, the end of the dispersing rod can move in the transverse groove, and both ends of the plug rod can move in the inner groove. When the dispersing rod descends, the swing plate swings along the swing axis.

[0015] Preferably, when the movable frame moves between the side plates, the L-shaped plate and the transverse plate are located in the slot, and the L-shaped plate and the transverse plate can move in the slot. The round steel is placed on the surface of the support, and the side plates play a limiting role for the round steel.

[0016] A method of using a round steel bar unloading and stacking device includes the following steps:

[0017] Step 1: Rolling. The lifting rod moves the moving frame, causing the round steel to adhere to the bottom of the electromagnetic plate. The piston rod is driven by the cylinder inside the slot to move downward. The piston rod moves the dispersing rod, which in turn moves the connecting rod, causing the swing plate to swing around the swing axis. The connecting rod moves in the inner slot, causing the swing plate to be in an inclined state. The round steel rolls on the surface of the electromagnetic plate, so that the round steel on both sets of electromagnetic plates is concentrated in the middle of the moving frame. When the round steel rolls on the surface of the electromagnetic plate, it will contact the rubber plate and rubber strip. Under the support of the rubber plate and rubber strip, the round steel keeps rolling slowly and prevents it from falling off the surface of the electromagnetic plate.

[0018] Step 2: Stacking. When the moving frame moves between the side plates, the gear is driven by the motor to rotate. The teeth on the surface of the gear mesh with the grooves on the surface of the transverse plate. The rotation of the gear drives the transverse plate to move. The top holding plate at the end of the transverse plate moves with the transverse plate and holds the already stacked round steel on the surface, so that the stacked round steel is moved to both sides. After the round steel on the electromagnetic plate falls off, it is located in the middle position, so that the round steel can be evenly stacked on the surface of the support.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention proposes a method where the swing plate is tilted, and the round steel rolls on the surface of the electromagnetic plate. This concentrates the round steel on both sets of electromagnetic plates in the middle of the moving frame. As the round steel rolls on the electromagnetic plate, it comes into contact with the rubber plate and rubber strip. The rubber plate and rubber strip hold the round steel in place, preventing it from falling off the electromagnetic plate. The limiting plate and limiting strip also act as limiters, keeping the round steel on the surface of the swing plate. When the moving frame moves between the side plates, the motor drives the gear to rotate. The teeth on the gear surface mesh with the grooves on the transverse plate surface. The rotation of the gear drives the transverse plate to move. The top plate at the end of the transverse plate moves with the transverse plate and holds the already stacked round steel on the surface. This moves the stacked round steel to both sides, and the round steel that falls off the electromagnetic plate is located in the middle, allowing the round steel to be evenly stacked on the surface of the support.

[0034] Example 2: Based on Example 1, the lifting rod 1 can drive the movable frame 2 to move. A support 3 is placed at the bottom of the movable frame 2. A side plate 4 is fixed to the surface of the support 3. A slot 5 is opened on the surface of the side plate 4. Through slots 6 are opened on the surfaces of the lifting rod 1 and the movable frame 2. A round steel 7 is placed at the bottom of the movable frame 2. The electromagnetic plate 10 can attract the round steel 7 to the surface. Two sets of swing plates 8 are set at the bottom of the movable frame 2. Limit plates 9 are fixed on both sides of the bottom of the swing plates 8. One end of the swing plates 8 is fixed A limit bar 26 is provided, and a swing shaft 22 is provided at the other end of the swing plate 8. An arc plate 21 is fixed at the bottom of the movable frame 2. The swing plate 8 is hinged to the end of the arc plate 21 through the swing shaft 22. The swing plate 8 can swing along the swing shaft 22. After the swing plate 8 is tilted, the round steel 7 can roll on the surface of the electromagnetic plate 10. After the round steel 7 rolls on the surface of the electromagnetic plate 10, it presses against the surface of the rubber strip 25 and the rubber plate 24, so that the rubber strip 25 and the rubber plate 24 are retracted into the interior of the groove 23 and fixed in the through groove 6. A cylinder 30 is provided, and a piston rod 35 is provided at the end of the cylinder 30. The cylinder 30 can drive the piston rod 35 to move up and down.

When the dispersing rod 31 descends, the swing plate 8 swings along the swing axis 22. The dispersing rod 31 drives the plug rod 32 to move, so that the swing plate 8 swings around the swing axis 22, and the plug rod 32 moves in the inner groove 34, so that the swing plate 8 is in an inclined state. The round steel 7 rolls on the surface of the electromagnetic plate 10, so that the round steel 7 on the surfaces of the two sets of electromagnetic plates 10 are concentrated in the middle position of the moving frame 2.

[0035] The surface of the movable frame 2 is provided with a swing groove 15, in which a rotating shaft 18 is provided. The rotating shaft 18 can rotate in the swing groove 15 and is fixed to the end of the L-shaped plate 16. The L-shaped plate 16 can swing along the rotating shaft 18. A first extension block 11 and a second extension block 13 are fixed to the surface of the movable frame 2. A pushing device is provided inside the first extension block 11. Two sets of positioning plates 12 are inserted into the surface of the first extension block 11. The positioning plates 12 can extend and retract inside the first extension block 11. The pushing device is connected to the end of the positioning plate 12 and pushes the positioning plate 12 to move it. The movable frame 2 moves to the side. When the plates 4 are in the slot 5, the L-shaped plate 16 and the transverse plate 27 are located in the slot 5 and can move in the slot 5. The round steel 7 is placed on the surface of the support 3, and the side plate 4 acts as a limit for the round steel 7. The round steel 7 will contact the rubber plate 24 and the rubber strip 25. Under the support of the rubber plate 24 and the rubber strip 25, the round steel 7 is kept rolling slowly to prevent the round steel 7 from falling off the surface of the electromagnetic plate 10. The limiting plate 9 and the limiting strip 26 act as a limit to keep the round steel 7 on the surface of the swing plate 8. When the moving frame 2 moves between the side plates 4, the gear 19 is driven to rotate by the motor 20.

[0036] The surface of the second extension block 13 is provided with an insertion groove 14. After the positioning plate 12 moves, it can be inserted into the insertion groove 14. The other end of the L-shaped plate 16 is fixed with a connecting block 17. The surface of the L-shaped plate 16 is fixed with a motor 20. The motor 20 swings with the L-shaped plate 16. The end of the motor 20 is provided with a gear 19. The motor 20 can drive the gear 19 to rotate. The inside of the connecting block 17 is inserted with a transverse plate 27. The transverse plate 27 can move inside the connecting block 17. The surface of the transverse plate 27 is provided with a toothed groove 29. The toothed groove 29 meshes with the teeth on the surface of the gear 19. After the gear 19 rotates, it can drive the transverse plate 27 to move. One end of the transverse plate 27 is fixed with a top holding plate 28. The top holding plates 28 at the ends of the two sets of transverse plates 27 approach each other. The top holding plates 28 move with the transverse plate 27. The toothed groove 29 is located on the top of the transverse plate 27, and multiple sets of toothed grooves 29 are provided.

[0037] The lifting rod 1 moves the moving frame 2, causing the round steel 7 to adhere to the bottom of the electromagnetic plate 10. The cylinder 30 inside the through groove 6 drives the piston rod 35 downwards. The piston rod 35 moves the dispersing rod 31, which in turn moves the insertion rod 32, causing the swing plate 8 to swing around the swing axis 22. The insertion rod 32 moves within the inner groove 34, tilting the swing plate 8. The round steel 7 rolls on the surface of the electromagnetic plate 10, concentrating the round steel 7 on both sets of electromagnetic plates 10 at the center of the moving frame 2. As the round steel 7 rolls on the electromagnetic plate 10, it contacts the rubber plate 24 and rubber strip 25. The rubber plate 24 and rubber strip 25 support the round steel 7, preventing it from detaching from the electromagnetic plate 10. The limiting plate 9 and limiting strip 26 also limit the movement, keeping the round steel 7 within the swing plate. When the moving frame 2 moves between the side plates 4 and the moving plate 8, the gear 19 is driven to rotate by the motor 20. The teeth on the surface of the gear 19 mesh with the grooves 29 on the surface of the transverse plate 27. The rotation of the gear 19 drives the transverse plate 27 to move. The top plate 28 at the end of the transverse plate 27 moves with the transverse plate 27. The top plate 28 presses against the surface of the already stacked round steel 7, so that the stacked round steel 7 is moved to both sides. After the round steel 7 on the surface of the electromagnetic plate 10 falls, it is located in the middle position, so that the round steel 7 can be evenly stacked on the surface of the support 3. The L-shaped plate 16 can swing around the rotating shaft 18, so that the transverse plate 27 is located on both sides of the moving frame 2, which will not affect the adsorption of the round steel 7 by the electromagnetic plate 10. The positioning plate 12 is pushed by the pushing device inside the first extension block 11, so that the positioning plate 12 is stuck on the surface of the L-shaped plate 16, which can realize the position stability of the L-shaped plate 16.
