Description

Technical Field

[0001] This invention relates to the field of logistics transportation technology, and in particular to a lifting platform for logistics transfer. Background Technology

[0002] In modern logistics transfer systems, vertical transport of goods is a crucial link connecting different floor work areas. Common logistics transfer elevators mainly include vertical lifts and continuous bucket elevators. Among them, chain-type lifting platforms are widely used in logistics transfer centers and automated warehouse systems due to their advantages such as stable structure and strong load-bearing capacity.

[0003] In existing technologies, chain-type lifting platforms typically consist of a drive sprocket, a driven sprocket, a closed-loop chain, and multiple support platforms or hoppers fixed to the chain. The drive sprocket drives the chain in a cyclical motion, and the support platforms rise and fall with the chain, transporting goods from the bottom floor to the top floor, or vice versa. After the goods reach the target floor, they usually need to be unloaded from the support platforms manually or with auxiliary equipment, and then transferred to the floor's conveyor rollers or AGV trolleys.

[0004] However, existing logistics transfer elevators still have the following technical problems in practical applications: the conveying requirements of different sized goods vary, the size of the fork plates and the spacing between the fork teeth cannot be flexibly adjusted, and different load-bearing platforms need to be replaced when the bottom structure of the conveying pallets or bins is different. Moreover, existing elevators usually have fixed docking platforms on each floor for automatic docking of goods, but during the docking process, problems such as jamming and material slippage are prone to occur when dealing with irregularly shaped objects or goods with soft bottoms.

[0005] Therefore, it is necessary to design a logistics transfer elevator with high docking accuracy, adjustable forks, active docking capability between floors, and stable operation to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of poor docking accuracy, inability of the forklifts to adapt to different cargo specifications, and easy jamming when dealing with irregularly shaped objects or soft-bottomed cargo in existing logistics transfer elevators. Therefore, this invention proposes a logistics transfer elevator.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a lifting platform for logistics transfer, comprising a mounting plate, a transport component, and a docking component. A guide groove is formed on the surface of the mounting plate, and a guide component is slidably connected within the guide groove.

[0008] The transport assembly includes a drive gear, a tension gear, and a chain. A mounting rod is connected to the surface of the mounting plate. The drive gear and the tension gear are rotatably connected to the outer periphery of the mounting rod. The chain is wound between the drive gear and the tension gear. The transport assembly also includes forks for moving goods.

[0009] The docking assembly includes a docking frame, docking rollers, and an identification device. The docking frame is fixedly installed on the outside of the mounting plate, the docking rollers are rotatably connected to the inside of the docking frame, and the identification device is fixedly installed on the outside of the docking frame. The docking assembly also includes a telescopic assembly for controlling the extension and retraction of the docking frame. When the transport assembly moves the goods toward the docking assembly on the corresponding floor, the identification device identifies the corresponding goods and controls the telescopic assembly to extend the docking frame to dock with the goods.

[0010] In the above scheme, the transport component drives a chain via a drive gear to perform a closed-loop cycle. The forklifts rise and fall with the chain, transporting goods from the first floor to other floors. Each floor has an independently configured docking component. When the identification device detects that goods need to be unloaded on that floor, the telescopic component automatically drives the docking frame to extend and dock with the forklifts. The goods are then smoothly transferred to the floor conveyor line via docking rollers. This scheme achieves automatic identification and automatic docking and unloading of goods on each floor without manual intervention.

[0011] Preferably, the guide assembly includes a cross connecting rod, a pair of horizontal guide wheels, and a pair of vertical guide wheels. The cross connecting rod is rotatably connected to the chain, and the horizontal and vertical guide wheels are rotatably connected to the ends of the cross connecting rod, and the horizontal and vertical guide wheels are slidably connected within guide grooves.

[0012] In the above scheme, the cross connecting rod serves as the connector between the chain and the fork, with its horizontal and vertical guide wheels rolling within guide grooves. The horizontal guide wheel restricts the fork's swaying in the direction perpendicular to the plane of motion, while the vertical guide wheel bears the weight of the fork and the goods, ensuring smooth lifting. This dual-guide wheel structure allows the fork to maintain a stable posture under the chain's drive, especially when the chain passes through the turning area of ​​the drive gear and tension gear. The cooperation between the guide wheel and the guide groove effectively prevents the fork from tilting and shaking, significantly improving conveying stability.

[0013] Preferably, the fork plate includes a crossbeam, fork teeth, movable sliders, a lead screw, an electromagnet, and a fixing block. The crossbeam is rotatably connected to the center of the cross connecting rod. An adjustment groove is formed on the outer side of the crossbeam, and multiple movable sliders are slidably connected within the adjustment groove. The lead screw is rotatably connected to both sides of the adjustment groove and cooperates with the movable sliders. The fork teeth are fixedly connected to the surface of the movable slider. The electromagnet is fixedly connected inside the movable slider, and the fixing block is slidably connected to the outer side of the movable slider. Multiple fixing grooves are formed at the bottom of the adjustment groove, and the spacing between the fixing grooves is the same as the spacing between the conveyor rollers. When the electromagnet is energized, it drives the fixing block to disengage from the fixing groove; when the power is off, the fixing block is inserted into the fixing groove and locked under the action of a spring.

[0014] In the above scheme, when it is necessary to adjust the fork tooth spacing to accommodate pallets or bins of different sizes, the control system energizes the electromagnet, causing it to attract the fixing block and pull it out of the fixing slot, thus releasing the lock. Then, the drive screw rotates, causing the moving slider to slide along the adjustment slot, thereby adjusting the spacing between the fork teeth. After adjustment, the electromagnet is de-energized, and the fixing block automatically inserts into the corresponding fixing slot under the action of a spring, achieving self-locking. The spacing of the fixing slots is the same as the spacing of the floor conveyor rollers, ensuring that the fork teeth and conveyor rollers can interlock, facilitating smooth transfer of goods. This design allows the same elevator to quickly adapt to different sized cargo carriers without replacing the fork plates, significantly improving the equipment's versatility.

[0015] Preferably, the two ends of the thread on the lead screw surface are in opposite directions and are divided into multiple different thread segments along the lead screw axis, and the multiple thread segments have different leads.

[0016] In the above scheme, the lead screw is installed along the length of the crossbeam and driven to rotate by a single motor. The lead screw is divided into multiple threaded segments along its axial direction, each with a different constant lead. Multiple nuts are also provided, each fixed to a slider of a fork tooth. The forks are arranged symmetrically on the crossbeam, with N forks on each side of the center, numbered sequentially from the center outwards as tooth 1 to tooth N. The ratio of the lead of the threaded segments corresponding to each fork tooth on the lead screw is 1:3:5…:(2N-1). This ensures that when the motor drives the lead screw to rotate the same number of revolutions, each nut causes the corresponding fork tooth to move a different distance along the crossbeam, thereby achieving synchronous and proportional adjustment of the fork tooth spacing, and ensuring that the travel distances of adjacent teeth do not overlap.

[0017] Preferably, the fork teeth have support grooves on both sides, and anti-jamming buckles are slidably connected inside the support grooves. The anti-jamming buckles have an arc-shaped surface, and compression springs are connected to the surfaces adjacent to the support grooves and the anti-jamming buckles.

[0018] In the above design, when the fork tines are inserted into the gap at the bottom of the pallet, the arc-shaped anti-jamming buckle is compressed and retracted into the support groove upon contact with the pallet edge, preventing hard jamming. Once the fork tines are fully in place, the anti-jamming buckle pops out under the action of the compression spring, abutting against the bottom structure of the pallet from the side, preventing goods from slipping off the fork tines during lifting. This design ensures smooth insertion of the fork tines and provides a reliable anti-slip function, improving conveying safety. It also avoids the problem of fork tines deviating after prolonged operation, which could lead to rigid collisions between the rollers and the fork tines.

[0019] Preferably, the upper surface of the fork tooth is connected to a plurality of floating support blocks, and the surface of the floating support blocks is fitted with rubber pads.

[0020] In the above solution, the floating support block can adaptively float slightly according to the shape of the cargo's bottom, increasing the contact area between the fork teeth and the cargo and preventing stress concentration that could damage the cargo's bottom. The rubber pad further increases the coefficient of friction, preventing the cargo from slipping during lifting and lowering, while also providing cushioning and shock absorption to protect fragile goods.

[0021] Preferably, the telescopic assembly includes a hydraulic telescopic rod, a telescopic frame, and a transport roller. The telescopic frame is slidably connected to the outside of the docking frame, the telescopic end of the hydraulic telescopic rod is fixedly connected to the outside of the telescopic frame, and the transport roller is installed on the side of the telescopic frame.

[0022] In the above scheme, when the identification device detects that goods need to be unloaded on this floor, the hydraulic telescopic rod drives the telescopic frame to extend outward from the docking frame, bringing the transport roller at the front end of the telescopic frame closer to the fork plate. The transport roller and fork teeth are arranged alternately. When the goods on the fork plate are pushed, the goods transfer from the fork teeth to the transport roller, and then are transported to the floor conveyor line via the docking roller. The telescopic action is responsive and forms a stable bridge after telescopic completion, eliminating the gap between the elevator and the floor conveyor line, achieving seamless docking.

[0023] Preferably, a baffle is connected to the outside of the docking frame, and a deflector plate is installed at the connection between the docking frame and the docking roller.

[0024] In the above scheme, the baffle is used to prevent goods from falling off the side of the docking frame during the docking and conveying process, serving as a limit and protection function. The deflector plate is set at the starting end of the docking roller, and its surface is arc-shaped or inclined. When the goods transition from the fork plate to the docking roller, the deflector plate guides the goods smoothly into the docking roller area, avoiding jamming or impact caused by height differences or gaps, further improving the smoothness of docking. At the same time, in the event of a jamming problem, the deflector plate can drive the entire docking roller to deflect, thereby solving the jamming problem.

[0025] Compared with existing technologies, the advantages of this invention are: 1. This invention achieves rapid adaptation of the fork plate to different specifications of goods by setting up a fork tooth spacing adjustment mechanism composed of a movable slider, a lead screw, an electromagnet, and a fixed block. The lead screw is driven by a single motor and is divided into multiple threaded segments with different leads along the axial direction. The ratio of the leads of each threaded segment is 1:3:5…:(2N-1), so that when the motor rotates for the same number of revolutions, the moving distance of each fork tooth increases in an arithmetic sequence, thereby achieving synchronous and proportional adjustment of the fork tooth spacing. This design can achieve precise proportional adjustment without a complex control system, greatly improving the versatility of the lifting platform.

[0026] 2. This invention, through its anti-jamming structure, ensures smooth insertion of the fork teeth into the pallet while providing reliable anti-detachment functionality. Furthermore, when the chain undergoes tensile deformation or the fork teeth experience slight positional deviations after prolonged operation, the anti-jamming arc surface, in conjunction with the compression spring, acts as a buffer, preventing rigid collisions between the rollers and the fork teeth, effectively protecting both the equipment and the goods. The deflection function of the deflection plate further resolves the material jamming problem, ensuring the continuity of logistics transfer.

[0027] 3. This invention achieves automatic identification and unloading of goods on each floor by setting up an active docking assembly consisting of an identification device, a telescopic component, a docking frame, and transport rollers. When the identification device detects that goods need to be unloaded on this floor, the hydraulic telescopic rod drives the telescopic frame to extend automatically, and the transport rollers and fork teeth work in an alternating manner, so that the goods are transported to the floor conveyor line automatically. The entire process requires no manual intervention, thus speeding up work efficiency. Attached Figure Description

Detailed Implementation

[0030] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0031] Reference Figures 1 to 10 A logistics transfer elevator includes a mounting plate 1, a transport component 2, and a docking component 3.

[0032] The mounting plate 1 has a guide groove 11 on its surface, and a guide component 12 is slidably connected in the guide groove 11. The mounting plate 1 is fixedly installed on the frame of the elevator, and the guide groove 11 is in a closed loop shape, matching the movement trajectory of the guide component.

[0033] The transport assembly 2 includes a drive gear 21, a tension gear 22, and a chain 23. A mounting rod 24 is attached to the surface of the mounting plate 1, and the drive gear 21 and tension gear 22 are rotatably connected to the outer periphery of the mounting rod 24. The drive gear 21 is driven to rotate by a geared motor. The chain 23 is wound between the drive gear 21 and the tension gear 22, forming a closed loop. The tension gear 22 can be adjusted to tension the chain 23, ensuring smooth transmission. The transport assembly 2 also includes forks 25 for moving goods.

[0034] The docking assembly 3 includes a docking frame 31, docking rollers 32, an identification device 33, and a telescopic assembly 34. The docking frame 31 is fixedly installed on the outside of the mounting plate 1, corresponding to the unloading port position of each floor. The docking rollers 32 are rotatably connected to the inside of the docking frame 31, and multiple docking rollers 32 are arranged in parallel to form a roller conveyor. The identification device 33 is fixedly installed on the outside of the docking frame 31. In this invention, the identification device 33 can be an RFID reader or a vision camera, used to identify tags or feature codes on the goods. The docking assembly 3 also includes a telescopic assembly 34 for controlling the extension and retraction of the docking frame 31; when the transport assembly 2 moves the goods toward the docking assembly 3 on the corresponding floor, the identification device 33 identifies the corresponding goods and controls the telescopic assembly 34 to extend the docking frame 31 to dock with the goods. The telescopic assembly 34 includes a hydraulic telescopic rod 341, a telescopic frame 342, and a transport roller 343. The telescopic frame 342 is slidably connected to the outside of the docking frame 31 and can extend or retract in the horizontal direction. The fixed end of the hydraulic telescopic rod 341 is connected to the docking frame 31, and its telescopic end is fixedly connected to the outside of the telescopic frame 342 for driving the telescopic frame 342 to extend and retract. The transport rollers 343 are installed on the side of the telescopic frame 342, and multiple transport rollers 343 are arranged in parallel with the same spacing as the spacing of the fixed grooves 258, so that the transport rollers 343 can be staggered with the fork teeth 252.

[0035] A baffle 35 is connected to the outer side of the docking frame 31 to prevent goods from falling from the side. A deflector plate 36 is installed at the connection between the docking frame 31 and the docking roller 32. The deflector plate 36 has an arc-shaped inclined surface, which guides the goods to smoothly transition from the fork plate 25 to the docking roller 32. When a jamming problem occurs, the deflector plate 36 can drive the docking roller 32 to deflect as a whole, thereby changing the docking angle to solve the jamming problem and ensure smooth material conveying.

[0036] Reference Figure 3 The guide assembly 12 includes a cross-shaped connecting rod 121, a pair of horizontal guide wheels 122, and a pair of vertical guide wheels 123. The center of the cross-shaped connecting rod 121 is rotatably connected to a link of the chain 23 and moves with the chain 23. Two horizontal guide wheels 122 and two vertical guide wheels 123 are rotatably connected to the four ends of the cross-shaped connecting rod 121, respectively. The axes of the horizontal guide wheels 122 are perpendicular to the surface of the mounting plate 1, used to constrain the displacement of the fork plate 25 in a direction perpendicular to the plane of motion; the axes of the vertical guide wheels 123 are parallel to the surface of the mounting plate 1, used to bear gravity and ensure stability in the lifting direction. Both the horizontal guide wheels 122 and the vertical guide wheels 123 are slidably connected within the guide groove 11 and roll along the trajectory of the guide groove 11.

[0037] Reference Figure 4 - Figure 9The fork plate 25 includes a crossbeam 251, fork teeth 252, movable sliders 253, a lead screw 254, an electromagnet 255, and a fixing block 256. The crossbeam 251 is rotatably connected to the center of the cross connecting rod 121 and can swing slightly relative to the cross connecting rod 121 to accommodate installation errors. An adjustment groove 257 is provided on the outer side of the crossbeam 251, extending along the length of the crossbeam 251. Multiple movable sliders 253 are slidably connected in the adjustment groove 257. The fork teeth 252 are arranged in a centrally symmetrical manner on the crossbeam 251, with multiple fork teeth 252 on each side of the center, numbered sequentially from the center outwards as tooth 1, tooth 2, tooth 3... tooth N. The lead screw 254 is rotatably connected between the two side walls of the adjustment groove 257, passing through each movable slider 253 and threadedly engaging with a nut fixed inside the movable slider 253. The fork tooth 252 is fixedly connected to the surface of the movable slider 253 and moves synchronously with the movable slider 253.

[0038] Reference Figure 4 - Figure 9 The lead screw 254 is installed along the length of the crossbeam 251 and is driven to rotate by a single micro motor. The threads on the surface of the lead screw 254 have opposite directions at both ends and are divided into multiple different thread segments along the axial direction of the lead screw 254, each with a different constant lead. In this embodiment, corresponding to the 1st, 2nd, 3rd...Nth teeth on the left and right sides of the center, the ratio of the lead of the thread segments corresponding to each fork tooth 252 on the lead screw 254 is 1:3:5...2N-1. Specifically, the lead of the thread segment corresponding to the 1st tooth is P, the lead of the thread segment corresponding to the 2nd tooth is 3P, the lead of the thread segment corresponding to the 3rd tooth is 5P, and the lead of the thread segment corresponding to the Nth tooth is 2N-1P. When the motor drives the lead screw 254 to rotate the same number of revolutions, the distance that each nut drives the corresponding fork tooth 252 to move along the crossbeam 251 is proportional to the lead. That is, the first tooth moves a distance of d, the second tooth moves a distance of 3d, the third tooth moves a distance of 5d, and the lead of the thread segment corresponding to the d tooth is 2d-1. This achieves synchronous and proportional adjustment of the spacing between each fork tooth 252, and the travel of adjacent teeth does not overlap.

[0039] Reference Figure 4 - Figure 9An electromagnet 255 is fixedly connected inside the movable slider 253. A fixing block 256 is slidably connected to the outside of the movable slider 253, and the bottom end of the fixing block 256 has a slope or hemispherical surface. Multiple fixing slots 258 are provided at the bottom of the adjusting groove 257, and the spacing of the fixing slots 258 is the same as the spacing of the floor conveyor rollers 343. A return spring is provided between the fixing block 256 and the movable slider 253, and this return spring always pushes the fixing block 256 towards the fixing slot 258. When the electromagnet 255 is energized, it generates magnetic force, attracting the fixing block 256 and causing it to move upward against the spring force, disengaging from the fixing slot 258; when the electromagnet 255 is de-energized, the fixing block 256 automatically inserts into the fixing slot 258 under the action of the spring, achieving locking.

[0040] Reference Figure 4 - Figure 9 The fork tooth 252 has support grooves 2521 on both sides, and an anti-jamming buckle 2522 is slidably connected inside the support groove 2521. The surface of the anti-jamming buckle 2522 is arc-shaped. A compression spring 2523 is connected to the adjacent surface of the support groove 2521 and the anti-jamming buckle 2522. When the fork tooth 252 is inserted into the bottom of the pallet, the arc-shaped anti-jamming buckle 2522 is compressed and retracted into the support groove 2521 when it contacts the edge of the pallet. When the fork tooth 252 is fully in place, the anti-jamming buckle 2522 pops out under the action of the compression spring 2523, and abuts against the bottom structure of the pallet from the side to prevent the goods from slipping. When the chain 23 is stretched and deformed after the equipment has been running for a long time, causing a slight positional deviation of the fork tooth 252, the arc surface of the anti-jamming buckle 2522 can be compressed and retracted when it contacts the docking roller 32, avoiding rigid collision and playing a buffer protection role.

[0041] Reference Figure 8 Multiple floating support blocks 259 are connected to the upper surface of the fork tooth 252. The floating support blocks 259 are connected to the fork tooth 252 by small springs and can float up and down. Rubber pads 2591 are installed on the surface of the floating support blocks 259 to increase friction and provide a cushioning effect.

[0042] The working process of this invention is as follows: In the initial state, the docking components 3 of each floor of the elevator are in the retracted state, and the telescopic frame 342 is stored in the docking frame 31. The drive gear 21 of the transport component 2 drives the chain 23 to move in a cycle, and the fork plate 25 rises and falls with the chain 23.

[0043] When the spacing between the fork tines 252 needs to be adjusted to accommodate goods of different sizes, the control system energizes the electromagnet 255. The electromagnet 255 attracts the fixing block 256, causing it to be pulled out of the fixing slot 258 and released from its lock. Then, it drives the lead screw 254 to rotate. Since the lead ratio of each thread segment on the lead screw 254 is 1:3:5, the movement distance of each fork tine 252 is proportional, achieving synchronous and proportional adjustment of the fork tine spacing. After adjustment, the electromagnet 255 is de-energized, and the fixing block 256 automatically inserts into the corresponding fixing slot 258 and locks in place under the action of a spring.

[0044] When goods need to be transported from the bottom floor to a designated floor, the operator or upstream equipment places the pallet containing the goods onto the fork plate 25. The fork teeth 252 of the fork plate 25 insert into the bottom of the pallet. The anti-jamming latch 2522 is compressed and retracted upon contact with the edge of the pallet. After fully engaging, it pops out under the action of the compression spring 2523 to hold the bottom of the pallet, preventing the goods from slipping. Floating support blocks 259 and rubber pads 2591 provide stable support and cushioning. The control system determines the target floor based on the goods information, drives the gear 21 to rotate, and the fork plate 25 rises with the chain 23.

[0045] During the ascent, the horizontal guide wheel 122 and the vertical guide wheel 123 at the end of the cross connecting rod 121 roll along the guide groove 11. The horizontal guide wheel 122 restricts the horizontal sway of the fork plate 25, while the vertical guide wheel 123 bears the weight of the goods and ensures the stability of vertical lifting. When the chain 23 passes through the turning area of ​​the drive gear 21 or the tension gear 22, the cooperation between the guide wheel and the guide groove 11 effectively prevents the fork plate 25 from tilting.

[0046] When the forklift 25 reaches the target floor, the identification device 33 of that floor detects the identification code on the goods and confirms that the goods need to be unloaded on this floor. The control system issues a command, the hydraulic telescopic rod 341 extends, and drives the telescopic frame 342 to move towards the forklift 25 until the transport roller 343 and the fork teeth 252 are interlocked.

[0047] Subsequently, the unloading device pushes the goods from the fork plate 25 to one side of the docking assembly 3. The goods transfer from the fork teeth 252 to the transport roller 343, and after being guided by the deflector plate 36, they enter the docking roller 32, which transports the goods to the floor conveyor line. The baffle 35 prevents the goods from falling from the side. If a jamming problem occurs, the deflector plate 36 can drive the docking roller 32 to deflect as a whole, thus resolving the jamming.

[0048] After unloading is completed, the identification device 33 confirms that the goods have left, the control system controls the hydraulic telescopic rod 341 to retract, and the telescopic frame 342 returns to the docking frame 31. The fork plate 25 continues to move with the chain 23, returning to the bottom layer for the next conveying cycle.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
