Description

Technical Field

[0001] This utility model belongs to the field of material line buffer stop technology, specifically, it relates to a buffer stop device. Background Technology

[0002] A logistics line, also known as a logistics production line, is a system organized in an assembly line manner. Pallet conveyors are a key component of a logistics line, mainly used to transport palletized goods from one place to another. Through pallet conveyors, materials and products can be transferred quickly and accurately on the logistics line, thereby improving logistics efficiency.

[0003] Chinese patent application CN202421064105.9 discloses a pallet buffer stopper, including a pallet conveyor belt; a check block for limiting the limit block and preventing the pallet from rebounding is installed on the top of the limiting seat; two stops for stopping the pallet are installed on the top of the lifting plate; when the electric cylinder drives the lifting plate to rise, the lifting plate drives the stops to rise. When the front end of the pallet contacts the stop, the slider moves along the sliding cavity under the action of kinetic energy, thereby compressing the spring. Under the elastic action of the spring, the kinetic energy of the pallet can be buffered. At the same time, when the limit block passes the check block, the check block resets and protrudes behind the limit block. Under the restriction of the limit block by the check block, the pallet is unlikely to rebound. This design can not only achieve buffer stopping of the pallet, but also prevent the pallet from rebounding, ensuring the accuracy of the pallet stopping position, which is beneficial to subsequent loading and unloading operations.

[0004] However, while the check block in the above device can assist the pallet in buffering and stopping, in actual use, although the pallet can squeeze and shrink the check block when it is not needed to stop, long-term use will cause friction on the pallet itself, resulting in wear and tear on the pallet and the check block. Moreover, the check block is not easy to replace, otherwise it will affect the production line, which is quite troublesome.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] The traction component can move the first toothed plate when the buffer stop mechanism is activated, and move the second toothed plate that meshes with the double-headed gear. The movement of the second toothed plate can move the limiting component, thereby further stopping and limiting the pallet without causing wear and tear on itself or the pallet, thus improving its service life.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-6 As shown, this embodiment provides a buffer stop device, including a pallet conveyor belt 1, on which mounting blocks 4 and a buffer stop mechanism are respectively provided. The pallet conveyor belt 1 is provided with two side plates 2, and an auxiliary sliding mechanism is provided on one side of the side plate 2. A pallet 3 cooperating with the auxiliary sliding mechanism is provided on the upper side of the buffer stop mechanism.

[0030] A limiting block 27 is provided on the lower side of the tray 3. A through groove 5 is provided in the mounting block 4. A movable plate 6, a first toothed plate 7 that slides in the through groove 5, and a double-headed gear 8 that rotates in the through groove 5 are respectively provided in the through groove 5. A limiting member that cooperates with the limiting block 27 is provided in the through groove 5. A second toothed plate 9 is provided on the lower side of the movable plate 6. The two ends of the double-headed gear 8 are respectively engaged with the first toothed plate 7 and the second toothed plate 9. A winding member and a traction member are respectively provided at the two ends of the first toothed plate 7, wherein the traction member is connected to the buffer stop mechanism.

[0031] One application of this embodiment is as follows: When it is necessary to stop the pallet 3, the buffer stop mechanism is first activated. The buffer stop mechanism can drive the first toothed plate 7 to move through the traction member. The movement of the first toothed plate 7 can drive the double-headed gear 8 to rotate. The rotation of the double-headed gear 8 can drive the second toothed plate 9 to rotate. The rotation of the second toothed plate 9 can drive the limiting member located on the moving plate 6 to move, and can limit the limiting block 27 on the pallet 3, thereby achieving the effect of limiting the pallet 3. When the limiting member is no longer needed, the limiting of the traction member can be released when the buffer stop mechanism is reset. Thus, under the setting of the winding member, the first toothed plate 7 can be driven to reset, and the above steps can be repeated in reverse. Finally, the limiting member can be retracted into the mounting block 4, thus completing the use of this device.

[0032] By means of the traction component, the first toothed plate 7 can be moved when the buffer stop mechanism is activated, and the second toothed plate 8, which meshes with the double-headed gear 8, can be moved. The movement of the second toothed plate 8 can move the limiting component, thereby further stopping and limiting the pallet 3 without causing wear and tear on itself or the pallet 3, thus improving its service life. With the winding component, when the buffer stop mechanism stops and retracts, the limiting component can be retracted by its own pressure. When it is not necessary to stop the pallet 3, friction between the two can be avoided, thus preventing wear and tear.

[0033] The buffer stop mechanism of this embodiment includes a connecting plate 10 elastically fitted to one side of the mounting block 4. A mounting plate 11 is provided on the upper side of the connecting plate 10. A T-shaped groove 12 is provided on the mounting plate 11. A T-shaped support plate 13 is provided in the T-shaped groove 12. A stop plate 14 is provided on the upper side of the T-shaped support plate 13. A cylinder connected to the mounting plate 11 is provided in the connecting plate 10. A cavity is provided in the mounting block 4. Two telescopic cylinders 15 located in the cavity are provided at one end of the connecting plate 10. A sliding rod 16 is slidably fitted on one side of each telescopic cylinder 15. An elastic ring 17 is provided at one end of each sliding rod 16. A first spring sleeved on the sliding rod 16 is provided on one side of the elastic ring 17. The traction component includes a connecting block provided on one side of the mounting plate 11, a rope wheel 20 fixedly installed on one side of the connecting plate 10, and a connecting rope 18 provided on one side of the connecting block. A rope groove is provided in the mounting block 4. The connecting rope 18 is connected to the first toothed plate 7 through the rope groove. The mounting plate 11 has multiple fixing bolts on its upper side, and the T-shaped support plate 13 has fixing holes that engage with the fixing bolts. With these fixing bolts, the stop plate 14 can be quickly disassembled by tightening the fixing bolts when it is damaged or needs replacement after prolonged use, facilitating rapid disassembly and assembly. The T-shaped design ensures greater stability of the replaced stop plate 14 after installation. Furthermore, the cylinder configuration allows the stop plate 14 on the mounting plate 11 to move, blocking the tray 3 that needs to be stopped. While moving, it can drive the first toothed plate 7 at one end of the connecting rope 18 to move, thereby facilitating the activation of the limiting component and assisting in stopping the tray 3. With the setting of the rope wheel 20, the connecting rope 18 can be limited, reducing the frictional wear of the connecting rope 18 and extending its service life. With the setting of the first spring, when the tray 3 hits the stop plate 14 and drives the mounting plate 11 to move, it can form a force opposite to the elastic force of the first spring, which can buffer each other and further improve the stability and accuracy of the stop plate 14 in actual use.

[0034] The winding component in this embodiment includes a winding wheel 19 disposed on one side of the inner wall of the through groove 5. A torsion spring is disposed on one side of the winding wheel 19, and a traction rope connected to the first toothed plate 7 is disposed on the winding wheel 19. With the winding wheel 19 disposed, the first toothed plate 7 can be reset by the traction rope under the rotational force of the torsion spring itself. Thus, when the stop plate 14 is not needed, the limiting component can be retracted into the through groove 5, avoiding any impact on the operation of the tray 3 and frictional wear.

[0035] The limiting component in this embodiment includes a support plate 21 disposed on a movable plate 6. One end of the support plate 21 is rotatably fitted with a check block 22. A second spring connected to the check block 22 is disposed on the upper side of the movable plate 6. The upper side of the check block 22 is inclined, and under the setting of the second spring, the tray 3 will be squeezed when it passes by. After being squeezed, the check block 22 can be reset under the elastic force of the second spring itself, and block the other side of the tray 3.

[0036] In this embodiment, multiple sliding grooves 23 are provided on both sides of the inner wall of the through groove 5, and limiting sliders 24 that slide within the sliding grooves 23 are provided on both sides of the movable plate 6. With the sliding grooves 23, the movable plate 6 can drive the limiting sliders 23 to slide within the sliding grooves 23 when it moves, thereby limiting the movement of the movable plate 6 and making it more stable during use.

[0037] The auxiliary sliding mechanism in this embodiment includes a sliding groove 25 disposed on one side of the side plate 2. Each of the four ends of the tray 3 is rotatably fitted with a pulley 26, which slides within the sliding groove 25. The pulleys 26 allow the tray 3 to rotate within the sliding groove 25 during movement, thus enhancing the stability of the tray 3 during movement.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
