Description

Technical Field

[0001] This invention relates to the field of timber conveying technology, and in particular to a trolley-type conveying device for timber warehouses. Background Technology

[0002] As a core raw material in construction, furniture, and packaging, the efficiency of timber storage and transportation directly impacts the overall operating costs and production efficiency of the industry chain. Trolley-type conveyor systems are widely used in automated storage and retrieval systems (AS / RS). Traditional timber storage primarily relies on flat storage yards and simple shelving, with transportation depending on forklifts, manual trolleys, and fixed roller conveyors / chain conveyors. This is no longer adequate for the development needs of large-scale, automated, and high-density AS / RS. While timber is being transported horizontally, it also needs to be transported to a designated height to meet the docking requirements of specific shelving levels or fixed workstations. Therefore, trolley-type conveyor systems are necessary. To this end, patent CN112320244B discloses a conveying device that can automatically rotate a pallet using a first 90° turning conveying mechanism and a second 90° turning conveying mechanism. Furthermore, a 180° rotating conveying mechanism can enable the workpiece on the pallet to rotate horizontally in situ, facilitating the gripping of the workpiece by the gripping tool. Therefore, this conveying device does not require manual operation, thereby improving conveying efficiency. In addition, the distance between the first and second linear conveying mechanisms is small, that is, the docking space between each conveying mechanism is small, thereby reducing the space occupied by the conveying device and improving the applicability and conveying stability of the conveying device. The existing technical solutions mentioned above have the following drawbacks: when in use, they cannot stably lift and transport the board-shaped wood vertically after horizontal transport, which makes it easy for the material to tip over, deviate, or slip during the posture change process, which is especially prominent in the transport of long and heavy boards. Summary of the Invention

[0003] The purpose of this invention is to provide a trolley-type conveying device for timber warehouses, which solves the defect of existing trolley-type conveying devices for timber warehouses that cannot stably lift and convey board-shaped timber vertically after horizontal conveying.

[0011] Preferably, the receiving plate and the positioning block form a sliding structure, and the piston and the air cylinder form a sliding structure.

[0012] Preferably, a correction mechanism is fixedly connected to the top of the horizontal conveyor.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: When the trolley-type conveying equipment for timber warehouses is in use, starting the first drive motor rotates the worm gear, causing the worm wheel to rotate and moving the chain meshed with the outer wall of the first sprocket. This allows the U-shaped lifting frame to continue lifting and conveying the board-shaped timber. Simultaneously, as the receiving frame rises, the guide rod slides along the guide grooves inside the guide plate, allowing multiple sets of limiting plates to continue clamping and positioning the board-shaped timber. Combined with the suction holes inside the U-shaped lifting frame, pre-positioning and suction before clamping are achieved, further improving the stability of vertical conveying of board-shaped timber of different sizes and increasing the efficiency of timber conveying in the warehouse. The specific method is as follows: By incorporating a conveying mechanism, a T-shaped chute, and a T-shaped slider, starting the first drive motor rotates the worm gear, causing the worm wheel to rotate. This, in turn, drives the first sprocket, which is fixedly connected to the outer wall of the first shaft, to rotate along the vertical conveyor frame. This causes the chain to move, thereby lifting the receiving frame plate, which is fixedly connected to the outer wall of the support rod. This allows the U-shaped lifting frame to continue lifting and conveying the board-shaped timber, facilitating stable lifting and conveying of the board-shaped timber. Furthermore, the cooperation between the worm gear and the worm wheel enables self-locking, preventing the board-shaped timber from falling in the event of a sudden power outage and improving the stability of the conveying process. The sliding cooperation between the T-shaped slider and the T-shaped chute further enhances the stability of the rising receiving frame plate. Furthermore, as the receiving frame rises, it drives the guide rod to slide along the guide groove inside the guide plate, causing the two guide rods to move towards each other. This causes multiple limiting plates to clamp and position the board-shaped timber. When the limiting plate contacts the edge of the board-shaped timber, and the guide rod is still sliding along the inclined groove below the guide groove, it drives the movable rod to slide along the sleeve, causing the movable block to compress the damping spring. This facilitates clamping and positioning when vertically conveying timber of different sizes, preventing the timber from shifting during vertical conveying and further improving the stability of conveying board-shaped timber. Furthermore, when the guide rod slides to the inclined groove above the guide groove, it will cause multiple sets of limit plates to release the clamping of the board-shaped wood, realizing the release after clamping and positioning, so that the robotic arm on the designated height shelf can more easily grab and unload the board-shaped wood, improve the efficiency of wood conveying, and thus improve the efficiency of warehouse conveying and stacking. Furthermore, as the guide rod slides along the inclined groove below the guide groove, the piston fixedly connected to one end of the movable column slides along the air cylinder, creating negative pressure inside the air cylinder, which drives the air delivery pipe to draw in air, and drives the adsorption holes opened inside the U-shaped lifting frame to draw in air, which facilitates the adsorption and pre-positioning of the board-shaped wood before clamping and positioning, further improving the stability of positioning and conveying the board-shaped wood. By incorporating a correction mechanism, the second drive motor can rotate the bidirectional lead screw, causing the two movable plates to slide towards each other and move the correction plate. When multiple sets of guide rollers are in contact with both sides of the board-shaped timber, the horizontal conveyor can be started to transport the timber. This will also drive the guide rollers to rotate along the support, which facilitates the guidance and correction of board-shaped timber of different sizes during horizontal transport, thereby improving the stability of timber transport.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-12 The present invention provides a trolley-type conveying device for timber warehouses, including a conveying trolley 1.

[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, a horizontal conveyor 2 is mounted on the top of the conveyor trolley 1. A conveying mechanism 3 is fixedly mounted on the top of the horizontal conveyor 2. The conveying mechanism 3 includes a vertical conveying frame 31 fixedly mounted on the top of the horizontal conveyor 2. A protective cover 32 is mounted on the outer wall of the vertical conveying frame 31. A first drive motor 33 is fixedly connected to the outer wall of the protective cover 32. A worm gear 34 is fixedly connected to the output shaft of the first drive motor 33 via a coupling. A worm wheel 35 is movably connected to the outer wall of the worm gear 34. A first rotating shaft 36 is fixedly connected to the inner wall of the worm wheel 35. A first sprocket 37 is fixedly connected to the outer wall of the first rotating shaft 36. A chain 371 is movably connected to the outer wall of the first sprocket 37. A second sprocket 372 is movably connected to the inner wall of the chain 371. A second rotating shaft 373 is fixedly connected to the inner wall of the second sprocket 372. A support rod 374 is fixedly connected to the inner wall of the chain 371. A receiving frame plate 38 is fixedly installed on the wall. A U-shaped lifting frame 39 is fixedly connected to the bottom of the receiving frame plate 38. The placement height of the U-shaped lifting frame 39 at its lowest point is lower than the conveying roller inside the horizontal conveyor 2. A worm gear 34 is meshed with a worm wheel 35. The worm wheel 35 forms a rotating structure with the vertical conveyor frame 31 through a first rotating shaft 36. A first sprocket 37 forms a rotating structure with the vertical conveyor frame 31 through a first rotating shaft 36. The first sprocket 37 is meshed with a chain 371. The chain 371 is meshed with a second sprocket 372. The second sprocket 372 forms a rotating structure with the vertical conveyor frame 31 through a second rotating shaft 373. A T-shaped groove 4 is opened inside the vertical conveyor frame 31. A T-shaped slider 5 is fixedly connected to the outer wall of the receiving frame plate 38. The T-shaped slider 5 forms a sliding structure with the vertical conveyor frame 31 through the T-shaped groove 4. The T-shaped slider 5 is symmetrically arranged about the central axis of the receiving frame plate 38.

[0020] By placing the board-shaped timber on the horizontal conveyor 2 and starting the horizontal conveyor 2, the board-shaped timber can be horizontally transported to the top of the U-shaped lifting frame 39. Starting the first drive motor 33 can rotate the worm 34. Since the worm 34 is meshed with the worm wheel 35, the worm wheel 35 can be rotated, which drives the first sprocket 37, which is fixedly connected to the outer wall of the first rotating shaft 36, to rotate along the vertical conveyor frame 31. Since the first sprocket 37 is meshed with the chain 371, and the chain 371 is meshed with the second sprocket 372, the chain 371 can be moved, thereby driving the receiving frame plate 38, which is fixedly connected to the outer wall of the support rod 374, to rise, so that the U-shaped lifting frame 39 continues to lift and transport the board-shaped timber. At this time, the T-shaped slider 5 slides stably along the T-shaped groove 4 opened inside the vertical conveyor frame 31.

[0021] Reference Figure 1 , Figure 6 , Figure 8 , Figure 9 and Figure 10As shown, a guide plate 311 is fixedly installed on the outer wall of the vertical conveyor frame 31. A guide groove 312 is formed inside the guide plate 311. A guide rod 313 is movably connected inside the guide groove 312. A sleeve 314 is fixedly connected to one end of the guide rod 313. A movable block 3141 is movably connected inside the sleeve 314. A movable rod 3142 is fixedly connected to one side of the movable block 3141. A damping spring 3143 is fixedly connected to the other side of the movable block 3141. A limit plate 315 is fixedly connected to one end of the movable rod 3142. The guide rod 313 and the guide plate 311 form a sliding structure through the guide groove 312. The sleeve 314 and the movable rod 3142 form a sliding structure through the movable block 3141. A receiving plate 3131 is fixedly connected to the outer wall of the guide rod 313. A movable column 3132 is fixedly connected to the outer wall of the receiving plate 3131. An air cylinder 3133 is movably connected to the outer wall of the support plate 3132. The air cylinder 3133 is fixedly installed on the top of the support plate 38. An air supply channel is opened inside the support plate 38. One end of the channel is connected to the U-shaped lifting frame 39. The two U-shaped lifting frames 39 in the middle are hollow. A piston 3134 is fixedly connected to one end of the movable column 3132. An air inlet valve 3135 is installed at the input end of the air cylinder 3133. An air supply pipe 3136 is fixedly connected to the outer wall of the air inlet valve 3135. An air outlet valve 3137 is installed at the output end of the air cylinder 3133. An air outlet pipe 3138 is fixedly connected to the outer wall of the air outlet valve 3137. An adsorption hole 3139 is opened inside the U-shaped lifting frame 39. A positioning block 6 is fixedly connected to the top of the support plate 38. The support plate 3131 and the positioning block 6 form a sliding structure. The piston 3134 and the air cylinder 3133 form a sliding structure.

[0022] As the receiving plate 38 rises, it causes the guide rod 313 to slide along the guide groove 312 inside the guide plate 311, causing the two guide rods 313 to move towards each other. This causes multiple limiting plates 315 to clamp and position the board-shaped timber. When conveying board-shaped timber of different sizes, when the limiting plate 315 contacts the edge of the board-shaped timber, and the guide rod 313 is still sliding along the inclined groove below the guide groove 312, it causes the movable rod 3142 to slide along the sleeve 314, causing the movable block 3141 to compress the damping spring 3143, thus achieving clamping and positioning when vertically conveying timber of different sizes. When the guide rod 313 slides to the inclined groove above the guide groove 312, it will cause multiple sets of limiting plates 315 to release the clamping of the board-shaped timber for fixation. The robotic arm on the high-rise rack grabs and unloads the board-shaped timber. As the guide rod 313 slides along the inclined groove below the guide groove 312, it drives the receiving plate 3131 to slide along the positioning block 6. This causes the piston 3134, which is fixedly connected to one end of the movable column 3132, to slide along the air cylinder 3133, creating negative pressure inside the air cylinder 3133. This causes the air supply pipe 3136 to draw air inward. At this time, the air inlet valve 3135 opens and the air outlet valve 3137 closes, causing the adsorption hole 3139 inside the U-shaped lifting frame 39 to adsorb and pre-position the board-shaped timber. When the limiting plate 315 releases the clamping and positioning of the board-shaped timber, the air inlet valve 3135 closes and the air outlet valve 3137 opens, causing the piston 3134 to reset and compress the air, which is then discharged from the air outlet pipe 3138.

[0023] Reference Figure 1 , Figure 11 and Figure 12 As shown, a correction mechanism 7 is fixedly connected to the top of the horizontal conveyor 2. The correction mechanism 7 includes a support crossbeam 71 fixedly installed on the top of the horizontal conveyor 2. A second drive motor 72 is fixedly connected to the outer wall of the support crossbeam 71. The output shaft of the second drive motor 72 is fixedly connected to a double-acting lead screw 73 via a coupling. A movable plate 74 is movably connected to the outer wall of the double-acting lead screw 73. A threaded groove 75 is opened inside the movable plate 74. A connecting plate 76 is fixedly connected to the bottom of the movable plate 74. A correction mechanism is fixedly connected to the bottom of the connecting plate 76. A plate 77 is fixedly connected to a bracket 771 on one side. A rotating rod 772 is movably connected inside the bracket 771. A guide roller 773 is fixedly connected to the outer wall of the rotating rod 772. An avoidance groove 78 is opened inside the support crossbeam 71. A two-way lead screw 73 is threadedly connected to a movable plate 74 through a threaded groove 75. The movable plate 74 and the support crossbeam 71 form a sliding structure. A connecting plate 76 forms a sliding structure with the support crossbeam 71 through the avoidance groove 78. The guide roller 773 forms a rotating structure with the bracket 771 through the rotating rod 772.

[0024] By starting the second drive motor 72, the bidirectional lead screw 73 can be rotated. Since the bidirectional lead screw 73 is threadedly connected to the movable plate 74 through the threaded groove 75, the two movable plates 74 can slide towards each other, causing the connecting plate 76 to slide along the clearance groove 78 opened inside the support crossbeam 71, so that the correction plate 77 moves. When the multiple sets of guide rollers 773 are in contact with the two sides of the board-shaped wood, the horizontal conveyor 2 can be started to transport the wood, and will drive the guide rollers 773 to rotate along the bracket 771, so as to achieve guidance and correction when the board-shaped wood is transported horizontally.
