Description

Technical Field

[0001] This utility model relates to the field of logistics conveying equipment technology, specifically to an anti-collision and anti-tipping device for automated production lines. Background Technology

[0002] In modern warehousing and logistics systems, automated pallet conveyor lines are widely used. Currently, operators typically use forklifts to place pallets carrying goods at the beginning of the conveyor line. To prevent pallets from slipping off the side of the line or tipping over during transport, anti-tipping blocks are usually installed on the outermost side of the conveyor line.

[0003] However, existing anti-tipping blocks are generally installed in a forward-facing manner. The outermost anti-tipping block of the automated pallet conveyor line is installed in a conventional forward-facing manner. When operators use forklifts to place pallets on the conveyor line, collisions between the forks and the anti-tipping blocks occur frequently. This collision not only causes the goods to shake violently, but also accelerates the wear and tear of equipment parts, significantly affecting the service life of the production line. The total length of conventional forklift forks is shorter than the total length of the pallet. At the same time, the anti-tipping blocks prevent the pallet from being placed completely and stably against the surface of the conveyor line. Its outer side can only rest on the anti-tipping blocks. During the conveying process, the large height difference will generate inertial downward force, making the pallet risk of tipping over when moving, which threatens the safety of the goods.

[0004] Therefore, there is an urgent need for an anti-tipping device that can effectively reduce forklift collisions while ensuring stable pallet transport. Utility Model Content

The bottom end of the slide table is slidably connected to the support rail through the sliding groove.

[0010] As a preferred embodiment of the present invention, the surface of the second wedge block is provided with a sloping groove, and the bottom of the first wedge block is fixedly provided with a sloping protrusion, the sloping protrusion being slidably connected to the sloping groove.

[0011] As a preferred technical solution of this utility model, the top end of the semi-threaded screw is fixedly connected to the bottom end of the anti-tipping block, the threaded part of the semi-threaded screw is threaded with a nut, and notches are provided on the top of both sides of the sliding column, with the nut located inside the notch.

[0012] As a preferred technical solution of this utility model, the damping rubber pad is made of soft and hard rubber laminated and pressed together. A spring steel sheet is fixedly installed inside the damping rubber pad. Through holes are opened on the surface of the damping rubber pad and the top of the sliding column. The smooth round part of the semi-threaded screw is inserted and connected to the through holes.

[0013] As a preferred technical solution of this utility model, the self-locking component includes a rotating shaft, one end of which is fixedly connected to one end of a double-ended lead screw, and the other end of the rotating shaft is fixedly provided with a ratchet. A wrench position is provided in the middle of one side of the ratchet, and a pawl is engaged with the ratchet.

[0014] As a preferred technical solution of this utility model, a support shaft is fixedly provided on one side of the pawl, one end of the support shaft is rotatably connected to one side of the bracket, a torsion spring is sleeved on the surface of the support shaft, one end of the torsion spring is engaged with the pawl, and the other end of the torsion spring is engaged with a protruding plate, one side of the protruding plate is fixedly connected to one side of the bracket.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The anti-tipping block is securely installed on the outermost bracket of the conveyor line using a vertical fixing method, with the top of the anti-tipping block slightly higher than the bracket. This innovative installation method effectively buffers the impact force generated when the forklift places the pallet by changing the force direction and position of the anti-tipping block. The damping rubber pad provides cushioning and shock absorption between the anti-tipping block and the sliding column. At the same time, the design of the anti-tipping block being slightly higher than the bracket significantly reduces the risk of goods collision, forming a stable protective barrier, reducing the inertial downward force caused by height differences, and reducing the risk of pallet tipping during movement. It can provide effective support for goods during pallet transportation, greatly avoiding goods tipping and effectively ensuring the safe and stable operation of the automated pallet conveyor line.

[0017] 2. The double-ended lead screw can drive two adjustment components to move simultaneously. The adjustment components can adjust the height of the two anti-tipping blocks at the same time, which can cope with the manufacturing tolerances and wear of the equipment and pallets, and is suitable for pallets of different specifications and work processes. It can adapt to complex real-world working conditions. At the same time, the top of the anti-tipping block can be adjusted to be slightly higher than the support. The self-locking component can lock the double-ended lead screw to prevent it from rotating in the opposite direction, thus ensuring the load-bearing capacity of the anti-tipping block.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 An anti-collision and anti-tipping device for an automated production line includes a bracket 1. Two sliding columns 2 are slidably mounted on the top of one side of the bracket 1. Anti-tipping blocks 7 are fixedly mounted on the top of the sliding columns 2. Damping rubber pads 6 are mounted on the bottom of the anti-tipping blocks 7. Semi-threaded screws 10 are fixedly mounted on both sides of the bottom of the anti-tipping blocks 7. A wedge-shaped block 4 is fixedly mounted on the bottom of the sliding columns 2. A double-ended lead screw 14 is rotatably mounted in the middle of one side of the bracket 1. Adjustment components 15 for height adjustment of the wedge-shaped blocks 4 are mounted on both sides of the double-ended lead screw 14. A self-locking component 16 is mounted on one end of the double-ended lead screw 14. By vertically mounting the anti-tipping blocks 7 on the outside of the pallet conveyor line, the device effectively prevents tipping and tipping. Using a vertical fixing method, it is firmly installed on the outermost bracket 1 of the conveyor line, so that the top of the anti-tipping block 7 is slightly higher than the bracket 1. This innovative installation method can effectively buffer the impact force generated when the forklift places the pallet by changing the force direction and position of the anti-tipping block 7. The setting of the damping rubber pad 6 can provide buffering and shock absorption between the anti-tipping block 7 and the sliding column 2, significantly reducing the risk of goods collision. At the same time, the design of the anti-tipping block 7 being slightly higher than the bracket 1 forms a stable protective barrier, which can provide effective support for the goods during pallet transportation, greatly avoiding the tipping of goods and effectively ensuring the safe and stable operation of the automated pallet conveyor line. In this embodiment, preferably, the adjusting component 15 includes a slide table 1501. A threaded sleeve 1504, threadedly connected to the double-ended lead screw 14, is provided in the middle of the slide table 1501. A wedge block 1502, slidably connected to the first wedge block 4, is fixedly provided at the top of the slide table 1501. A groove 1505 is provided in the middle of the bottom end of the slide table 1501. A support rail 17 is fixedly provided on one side of the bracket 1. The bottom end of the slide table 1501 is slidably connected to the support rail 17 via the groove 1505. A sloping groove 15 is provided on the surface of the second wedge block 1502. 03. The bottom of the wedge block 4 is fixed with a sloping protrusion 5. The sloping protrusion 5 is slidably connected to the sloping groove 1503. The rotational motion of the double-ended screw 14 can be converted into the linear motion of the slide table 1501 through the threaded sleeve 1504. The slide table 1501 can drive the wedge block 2 1502 to move horizontally. The support rail 17 can support and guide it. The wedge block 2 1502 can drive the wedge block 4 to move vertically by relying on the sloping groove 1503 and the sloping protrusion 5, so as to adjust the height of the slide column 2 and the anti-tipping block 7. In this embodiment, preferably, the self-locking assembly 16 includes a rotating shaft 1601. One end of the rotating shaft 1601 is fixedly connected to one end of the double-ended lead screw 14. A ratchet 1602 is fixedly provided at the other end of the rotating shaft 1601. A wrench position 1603 is provided in the middle of one side of the ratchet 1602. A pawl 1604 is engaged with the ratchet 1602. A support shaft 1605 is fixedly provided on one side of the pawl 1604. One end of the support shaft 1605 is rotatably connected to one side of the bracket 1. A torsion spring 1606 is sleeved on the surface of the support shaft 1605. One end of the torsion spring 1606 is connected to the pawl 1604. The torsion spring 1606 is engaged with a protruding plate 1607 at the other end. One side of the protruding plate 1607 is fixedly connected to one side of the bracket 1. The double-ended screw 14 can be rotated through the wrench position 1603 and the rotating shaft 1601. The ratchet 1602 and the pawl 1604 can ensure the unidirectional rotation of the double-ended screw 14. After the double-ended screw 14 is rotated, the torsion spring 1606 can support the pawl 1604, which can engage with the ratchet 1602, thereby locking the rotating shaft 1601 and preventing the double-ended screw 14 from rotating in the opposite direction, thus ensuring the load-bearing capacity of the anti-tipping block 7. In this embodiment, preferably, an angle iron 3 is fixedly provided on the top of one side of the bracket 1 to guide the sliding column 2. The sliding column 2 is slidably connected to the angle iron 3. A protective plate 18 is fixed on one side of the bracket 1 by screws. Both sides of the top of the protective plate 18 are provided with working openings 19 corresponding to the sliding column 2. The angle iron 3 can guide the sliding column 2 and prevent the sliding column 2 from tilting. The protective plate 18 can provide protection for the double-ended lead screw 14 and the adjustment component 15. In this embodiment, preferably, the top end of the semi-threaded screw 10 is fixedly connected to the bottom end of the anti-tipping block 7, and the threaded part of the semi-threaded screw 10 is threadedly connected to the nut 11. Notches 12 are opened on the top of both sides of the sliding column 2, and the nut 11 is located inside the notch 12. The damping rubber pad 6 is made of soft and hard rubber stacked and pressed together. A spring steel sheet is fixedly installed inside the damping rubber pad 6. Through holes 13 are opened on the surface of the damping rubber pad 6 and the top end of the sliding column 2. The smooth round part of the semi-threaded screw 10 is inserted and connected to the through hole 13. The anti-tipping block 7 can be installed and removed through the semi-threaded screw 10 and the nut 11. Since the damping rubber pad 6 is made of soft and hard rubber stacked and pressed together, it takes into account both rigidity and deformation capacity. The spring steel sheet can prevent lateral buckling and can provide buffering and shock absorption between the anti-tipping block 7 and the sliding column 2. In this embodiment, preferably, a support 8 is fixedly provided at the top of the wedge block 4, one side of the top of the support 8 is fixedly connected to the bottom of the sliding column 2, and a stiffening plate 9 for reinforcing the sliding column 2 is fixedly provided on the other side of the top of the support 8. The wedge block 4 can provide support for the sliding column 2 through the support 8, and the stiffening plate 9 can improve the connection strength between the sliding column 2 and the support 8.

[0022] When in use, first locate the self-locking assembly 16 on the side of the device, and gently pull the pawl 1604 outward to disengage it from the ratchet 1602. At this time, the rotation lock of the double-ended screw 14 is released and can be adjusted. Then, put the special wrench (or socket) on the wrench position 1603 of the self-locking assembly 16, and drive the double-ended screw 14 to rotate through the rotating shaft 1601. The double-ended screw 14 drives the threaded sleeves 1504 at both ends to move synchronously towards the center, thereby pushing the two slides 1501 to slide towards the center along the support rail 17. The wedge block 1502 at the top of the slide 1501 moves horizontally accordingly. Because the inclined groove 1503 on the second wedge 1502 engages with the inclined protrusion 5 at the bottom of the first wedge 4, the horizontal movement is converted into the vertical upward movement of the first wedge 4. The first wedge 4 pushes the sliding column 2 to rise vertically under the guidance of the angle iron 3 through the support 8 and the stiffener 9, which eventually drives the anti-tipping block 7 to rise. The operation is reversed so that the two anti-tipping blocks 7 can fall synchronously until the top of the two anti-tipping blocks 7 is slightly higher than the top surface of the bracket 1. Then, the pawl 1604 is released. Under the elastic force of the torsion spring 1606, the pawl 1604 will automatically rebound and re-engage with the ratchet 1602, effectively preventing the double-ended screw 14 from rotating in the opposite direction due to vibration or load impact, thereby reliably locking the current height and ensuring the load-bearing capacity of the anti-tipping block 7. After the device is adjusted and locked, it can be put into daily use. The forklift driver transports the pallet to the end of the conveyor line. Since the anti-tipping block 7 is installed in reverse vertically with its protective surface facing outward, the collision is reduced during the entry and exit of the forks. If an impact occurs during placement, the force will be transmitted through the anti-tipping block 7 to the damping rubber pad 6 at its bottom. This pad is composed of a soft and hard rubber composite layer and a spring steel sheet, which can effectively absorb and attenuate the impact energy and play a role in buffering and shock absorption. After the pallet is placed, it begins to move along the conveyor line. The design of the top of the anti-tipping block 7 being higher than the bracket 1 forms a continuous protective barrier, reducing the inertial downward force caused by the height difference and reducing the risk of the pallet tipping over during movement. When the anti-tipping block 7 or the damping rubber pad 6 needs to be replaced due to wear from long-term use, use a tool to loosen and remove the two nuts 11 that fix the anti-tipping block 7 to the slide column 2. The nuts 11 are located in the notch 12 at the top of the slide column 2 for easy operation. After unscrewing the nuts 11, the half-threaded screw 10 can be pulled upward from the through hole 13 of the damping rubber pad 6 and the slide column 2 to remove the old anti-tipping block 7 and the damping rubber pad 6. Place the new damping rubber pad 6 on the top of the slide column 2, ensuring that its through hole 13 is aligned. Then, the smooth round part of the half-threaded screw 10 at the bottom of the new anti-tipping block 7 passes through the through hole 13 of the damping rubber pad 6 and the slide column 2 in sequence. Finally, put the nut 11 in the notch 12 of the slide column 2 and tighten it to complete the replacement.
