Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying mechanisms, specifically a lifting and conveying device. Background Technology
[0002] In automated logistics conveying systems, lifting conveyors are widely used in production lines, warehouse sorting, and other scenarios to achieve precise material positioning and transfer. Traditional conveyor systems mostly use stop cylinders or mechanical limiters to stop pallets, which suffers from low positioning accuracy, large impact, and easy pallet displacement or wear, especially under high-speed, high-load conditions where stability requirements are difficult to meet. In addition, the synchronous drive design of existing conveyor mechanisms is complex, and the contact method between the belt and the pallet is prone to wear, affecting the equipment's lifespan.
[0003] For example, Chinese patent CN109704048B discloses a pallet conveyor line that uses cylinder blocking blocks and synchronous belts to achieve alternating dual-station conveying. While this reduces manual intervention, its mechanical structure, relying on cylinder lifting and pusher plate pushing, requires multiple cylinders (blocks, pushers, lifting plates) and a linkage control system, increasing maintenance costs and the risk of failure. Furthermore, the lower surface of the pallet is flat, and during conveying, it can only be limited by the baffles on the outside of the synchronous belt, lacking an effective anti-deviation structure. This leads to lateral displacement due to inertia or external forces during conveying. Deviation is particularly pronounced under high-speed conveying or uneven load conditions, affecting positioning accuracy and accelerating wear on the conveyor belt and pallet. In addition, some solutions use additional guide wheels or sensors for correction, further increasing system complexity and cost.
[0004] Therefore, it is necessary to provide a line lifting and conveying device. Summary of the Invention
[0005] The present invention provides a lifting and conveying device that effectively solves the problems of low pallet positioning accuracy and the need for additional anti-deviation mechanisms in existing conveying devices to prevent pallet deviation.
[0006] The technical solution adopted in this utility model is:
[0007] The lifting and conveying device includes a conveyor line, a tray, and a lifting mechanism. The lifting mechanism includes a base, a cylinder mounted on the base, several linear bearings mounted vertically on the base, several lifting columns respectively fitted inside the linear bearings, a lifting plate connecting the upper ends of the lifting columns and connected to the output end of the cylinder, several positioning columns and positioning pins mounted on the lifting plate. The tray includes a base plate with positioning holes and L-shaped side plates on both sides of the base plate. The L-shaped side plates form a step with the outer side of the base plate, and the conveying surface of the conveyor line abuts against the L-shaped side plates.
[0008] Furthermore, the conveyor line includes a symmetrically arranged left conveyor line and a right conveyor line, and a conventional drive assembly that drives the left and right conveyor lines synchronously. The left conveyor line includes a support, a driving pulley and a driven pulley arranged at both ends of the support, and a belt that is driven and connected to the driving pulley and the driven pulley. The L-shaped side plate achieves horizontal movement through the belt drive.
[0009] Furthermore, the drive assembly includes a transmission shaft coaxially and fixedly connected to the drive pulley, and a motor reducer assembly disposed on the left side of the conveyor line. The motor reducer assembly is used to drive the transmission shaft.
[0010] Furthermore, the L-shaped side plate includes a vertical plate bolted to the side of the base plate, a flat plate connected to the upper end of the vertical plate, and a wear-resistant plate. The lower end of the flat plate, away from the vertical plate, is provided with an installation step for installing the wear-resistant plate. The wear-resistant plate is bolted to the flat plate, and the support is provided with a baffle on the side away from the tray.
[0011] Furthermore, both the left and right conveyor lines are equipped with end positioning components at one end. The end positioning components include a mounting block on the support, a bolt horizontally mounted on the mounting block, and a hydraulic damper, with the bolt and hydraulic damper corresponding to one end of the tray.
[0012] Furthermore, the conveyor line also includes a through-beam sensor and a reflection sensor mounted on the support. The through-beam sensor is used to detect the presence or absence of products in the tray, and the reflection sensor is used to detect the position of the tray.
[0013] Furthermore, the base plate is provided with through holes, and support blocks are provided on all four sides of the through holes.
[0014] The beneficial effects of the utility model are as follows: The structural design of the pallet can form a step to limit the movement of the conveyor line, preventing the pallet from deviating during the conveying process. By setting a lifting mechanism, the pallet can be lifted off the conveyor line and positioned by a positioning pin. Compared with the stopping cylinder, the stopping accuracy of the pallet is higher.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the lifting and conveying device provided in the embodiment of this application includes a conveying line 2, a tray 1, and a lifting mechanism. The lifting mechanism includes a base 31, a cylinder 32 mounted on the base 31, a plurality of linear bearings 33 mounted vertically on the base 31, a plurality of lifting columns 34 respectively sleeved in the linear bearings 33, a lifting plate 35 connecting the upper ends of the plurality of lifting columns 34 and connected to the output end of the cylinder 32, a plurality of positioning columns 37 and positioning pins 36 mounted on the lifting plate 35. The tray 1 includes a base plate 11 with positioning holes and L-shaped side plates 12 mounted on both sides of the base plate 11. The L-shaped side plates 12 and the outer side of the base plate 11 form a step 101. The conveying surface of the conveying line 2 abuts against the L-shaped side plates 12.
[0022] In actual use, the pallet 1 is moved by the conveyor line 2. When the pallet 1 moves to the predetermined position along the conveyor line 2, the cylinder 32 drives the lifting plate 35 to rise, so that the lifting plate 35 drives the positioning column 37 and the positioning pin 36 to move upward synchronously. The positioning pin 36 extends into the positioning hole of the base plate 11, and the upper end of the positioning column 37 contacts the lower end face of the base plate 11. As the lifting plate 35 continues to rise, it lifts the pallet 1, so that the L-shaped side plate 12 is separated from the conveyor line 2.
[0023] In the above design, the structure of pallet 1 can be limited by step 101 to prevent pallet 1 from deviating during the conveying process. By setting up a lifting mechanism, pallet 1 can be lifted off the conveying line 2 and positioned by positioning pin 36. Compared with the stop cylinder 32 stopping pallet 1, the stopping accuracy of pallet 1 is higher.
[0024] Specifically: such as Figure 4 As shown, the conveyor line 2 includes a symmetrically arranged left conveyor line 212 and a right conveyor line 222, and a conventional drive assembly 23 that drives the left conveyor line 212 and the right conveyor line 222 synchronously. The left conveyor line 212 includes a support 211, a driving pulley and a driven pulley arranged at both ends of the support 211, and a belt 212 that is connected to the driving pulley and the driven pulley. The L-shaped side plate 12 moves horizontally through the transmission of the belt 212.
[0025] In actual use, the drive assembly 23 drives the drive pulleys of the left conveyor line 212 and the right conveyor line 222 to rotate. With the cooperation of the two driven pulleys, the two belts 212 are driven. When the two belts 212 are driven, they respectively convey the two L-shaped side plates 12, thereby realizing the conveying of the pallet 1.
[0026] In the above design, the structural design and specific implementation of the conveyor line 2 ensure synchronous transmission of the two belts 212, effectively achieving stable conveying of the pallet 1.
[0027] Specifically: such as Figure 4 As shown, the drive assembly 23 includes a transmission shaft 231 coaxially and fixedly connected to the drive pulley, and a motor reducer assembly 232 disposed on the side of the left conveyor line 212. The motor reducer assembly 232 is used to drive the transmission shaft 231.
[0028] The motor-reducer assembly 232 includes a motor and a reducer. The motor and reducer are connected by a flange connection, that is, the motor shaft is connected to the input hole of the reducer through the flange, and then the motor and reducer are fixed with bolts 242. The reducer shaft is connected to the drive shaft 231 through a coupling.
[0029] In the above design, the structural design and specific implementation of the drive component 23 can effectively achieve synchronous and stable drive of the left conveyor line 212 and the right conveyor line 222.
[0030] Specifically: such as Figure 2As shown, the L-shaped side plate 12 includes a vertical plate 121 bolted to the side of the base plate 11, a flat plate 122 connected to the upper end of the vertical plate 121, and a wear-resistant plate 123. An installation step 101 for mounting the wear-resistant plate 123 is provided on the lower end of the flat plate 122 away from the vertical plate 121. The wear-resistant plate 123 is bolted to the flat plate 122. A baffle 213 is provided on the side of the support 211 away from the tray 1. The wear-resistant plate 123 is a polyurethane board.
[0031] In actual use, the wear-resistant plate 123 is in direct contact with the belt 212. The belt 212 drives the wear-resistant plate 123 to move, which causes the two L-shaped side plates 12 to move synchronously with the base plate 11, thus realizing the movement of the pallet 1.
[0032] In the above design, the structural design and specific implementation of the L-shaped side plate 12 can effectively achieve contact with the belt 212, ensuring the service life of the pallet 1.
[0033] Specifically: such as Figure 4 As shown, both the left conveyor line 212 and the right conveyor line 222 are provided with an end positioning component 24 at one end. The end positioning component 24 includes a mounting block 241 provided on the support 211, a bolt 242 horizontally provided on the mounting block 241, and a hydraulic buffer 243. The bolt 242 and the hydraulic buffer 243 correspond to one end of the tray 1.
[0034] In actual use, the pallet 1 moves along the conveyor line 2. One end of the pallet 1 first contacts the hydraulic buffer 243, causing the hydraulic buffer 243 to compress. Then, one end of the pallet 1 abuts against the bolt 242 and stops moving.
[0035] In the above design, the structural design and specific implementation of the end positioning component 24 can effectively stop the movement of the pallet 1, making it easier for the lifting mechanism to lift the pallet 1.
[0036] Specifically: such as Figure 1 As shown, the conveyor line 2 also includes a through-beam sensor 4 and a reflection sensor 5 disposed on the support 211. The through-beam sensor 4 is used to detect whether there is a product in the tray 1, and the reflection sensor 5 is used to detect the position of the tray 1.
[0037] In the above design, the through-beam sensor 4 and the reflection sensor 5 are designed to detect the presence or absence of the product and the tray 1.
[0038] Specifically: such as Figure 2 As shown, the base plate 11 is provided with a through hole, and support blocks 13 are provided on all four sides of the through hole.
[0039] In actual use, the product is supported by the support block 13, and the through holes can reduce the weight of the tray 1.
[0040] In the above design, the structural design of the base plate 11 facilitates the reduction of the weight of the pallet 1 and the load on the conveyor line 2.
[0041] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
