Description

Technical Field

[0001] This utility model relates to the field of stone slab processing technology, and in particular to a stone slab lifting and stacking device. Background Technology

[0002] The demand for slate materials in the building decoration field continues to rise, and the rapid removal and orderly stacking of slates after cutting has become a key bottleneck restricting capacity improvement. Traditional operations rely on operators to manually handle and stack slates one by one at the discharge port, which is not only labor-intensive, but also poses significant safety hazards as the stacking height increases, requiring personnel to repeatedly climb and bend over. It is also difficult to keep up with the continuous output rhythm of high-speed cutting equipment.

[0003] The common practice on existing production lines is to add fixed roller conveyors to move the cut stone slabs horizontally out first, and then manually push them to the stacking area using tools such as pry bars and rollers. Although this method partially reduces the intensity of direct handling, there is always a height and horizontal gap between the end of the roller conveyor and the stacking position, requiring on-site personnel to constantly adjust the pads and plates in order to continue stacking.

[0004] It is evident that the existing transfer process lacks an integrated device capable of simultaneously completing horizontal transfer and height-adaptive stacking, resulting in a mismatch between the cutting and stacking cycles, numerous operational steps, and low stacking accuracy. This has become a core issue restricting the efficiency of slate processing and on-site safety. Utility Model Content

[0005] The purpose of this invention is to propose a stone slab lifting and stacking device to solve the problem that the existing transfer process cannot simultaneously complete horizontal transfer and height adaptive stacking, resulting in many operation steps and low efficiency.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A stone slab lifting and stacking device includes a gantry frame located at the discharge port of a stone slab cutting device; a storage platform located on the side of the gantry frame away from the cutting device, on which stone slabs are stacked; a lifting device mounted on the gantry frame, the lifting device having a base plate for placing stone slabs; and a toggle device reciprocatingly mounted on the lifting device, the toggle device toggle stone slabs from the cutting device onto the base plate, and then from the base plate onto the storage platform.

[0007] By adopting the above technical solution, the gantry, storage platform, lifting device and toggle device form an integrated structure, which can directly complete the horizontal transfer, vertical lifting and stacking of stone slabs at the discharge port of the cutting equipment, reduce intermediate transfer links and improve the overall cycle matching degree.

[0008] Furthermore, the lifting device includes crossbeams fixedly mounted on both sides of the base plate, climbing wheels rotatably mounted on the crossbeams and moving up and down along the track, and a first motor fixedly mounted on the crossbeams and driving the climbing wheels to rotate. The two longitudinal beams of the gantry are vertically mounted with tracks for the climbing wheels to move up and down.

[0009] By adopting the above technical solution, the crossbeam, climbing wheels and the first motor form a rigid lifting mechanism. The climbing wheels rise and fall stably along the longitudinal beam track, ensuring that the base plate can accurately connect with the cutting equipment outlet and the top of the storage platform at different height positions.

[0010] Furthermore, a roller is rotatably mounted on the top of the gantry frame, and pulleys are fixedly mounted at both ends of the roller. A synchronous belt is meshed on the pulleys, and one end of the synchronous belt is fixedly mounted on the crossbeam, while the other end is fixedly mounted on a counterweight.

[0011] By adopting the above technical solution, the roller, pulley, synchronous belt and counterweight form a balanced lifting system, which counteracts the weight of the crossbeam and the base plate, reduces the load on the first motor, and improves the lifting stability and energy saving effect.

[0012] Furthermore, the actuating device includes a guide rail fixedly mounted on the crossbeam, a support frame that reciprocates along the length of the guide rail, and a lever spanning the support frame for actuating the stone slab, with the lever being raised and lowered on the support frame.

[0013] By adopting the above technical solution, the guide rail, support frame and liftable lever are integrated into the crossbeam, so that the lever has freedom in both the horizontal and vertical directions, realizing the continuous movement of the stone slab from the cutting equipment to the bottom plate, and then from the bottom plate to the storage platform.

[0014] Furthermore, rollers that abut against the guide rail are respectively provided on both sides of the bottom of the support frame, and a second motor that drives the rollers to rotate is fixedly installed on the support frame.

[0015] By adopting the above technical solution, the rollers roll along the guide rail and are driven by the second motor, ensuring high accuracy and speed in the reciprocating movement of the support frame and improving the efficiency of stone slab transfer.

[0016] Furthermore, a sliding frame is provided on the support frame for lifting, and the lever is fixedly mounted on the sliding frame.

[0017] By adopting the above technical solution, the sliding frame drives the lever to move up and down, so that the lever can adjust its height in real time according to the thickness of the stone slab and the stacking height, avoiding interference and improving the reliability of stacking.

[0018] Furthermore, the same track and climbing wheels as those on the lifting device are provided between the support frame and the sliding frame.

[0019] By adopting the above technical solutions, the track and climbing wheel structures can be reused, simplifying the types of parts and improving the consistency and stability of the sliding frame lifting.

[0020] Furthermore, a threaded sleeve is fixedly installed on the sliding frame, a lead screw that is screwed to the threaded sleeve is rotatably installed on the support frame, and a third motor that drives the lead screw to rotate is fixedly installed on the support frame.

[0021] By adopting the above technical solution, the lead screw and the lead sleeve form a precision lifting pair. The third motor drives the lead screw to rotate, realizing the precise up and down positioning of the sliding frame and the lever, improving the stacking accuracy and repeatability of positioning.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The stone slab lifting and stacking equipment described in this utility model integrates the gantry frame, storage platform, lifting device, and actuating device. It directly completes horizontal transfer, vertical lifting, and layer-by-layer stacking at the discharge port of the cutting equipment, significantly reducing manual handling. The crossbeams, climbing wheels, and longitudinal beam tracks work together to ensure precise docking of the base plate with the cutting equipment and storage platform at different heights, improving cycle time matching. Rollers, pulleys, synchronous belts, and counterweights form a balanced lifting system, reducing motor load and improving lifting stability. The guide rails, support frame, liftable lever, and lead screw sleeve work collaboratively to achieve precise stone slab actuation and height-adaptive stacking, improving stacking accuracy and operational safety.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] This embodiment relates to a stone slab lifting and stacking device, the overall structure of which is as follows: Figure 1 and Figure 2 As shown, it includes a gantry frame 1, a storage platform 2, a lifting device 3, and a toggle device 4.

[0031] The gantry frame 1 is located at the discharge port of the stone slab cutting equipment, the storage platform 2 is located on the side of the gantry frame 1, the lifting device 3 is lifted and lowered on the gantry frame 1, and the stone slab is lifted and lowered to a position parallel to the storage platform 2. The lifting device 3 is provided with a base plate 301 for the stone slab to move. The actuating device 4 moves back and forth on the lifting device 3, and the actuating device 4 drives the stone slab from the cutting equipment to the base plate 301, and then to the storage platform 2.

[0032] It is worth mentioning that the cutting equipment cuts large stone slabs into smaller stone slabs of different sizes for convenient use later. Since the cutting equipment is a common cutting machine in existing technology, it will not be described in detail here. The gantry frame 1 is located at the outlet of the cutting equipment. After the cutting is completed, the conveyor belt on the cutting equipment transports the stone slabs outward. The lifting device 3 is then raised and lowered by the gantry frame to a position level with the cutting equipment. Then, the actuating device 4 pulls the stone slabs on the cutting equipment onto the bottom plate 301. The actuating device 4 continues to move, pulling the stone slabs on the bottom plate 301 onto the storage platform 2. Then, the above operation is continued. The lifting device 3 can switch back and forth between the height of the cutting equipment and the height of the storage platform 2, thereby improving the stacking efficiency.

[0033] Based on the above overall introduction, this embodiment presents an exemplary structure of the stone slab lifting and stacking device, such as... Figure 2 and Figure 3 As shown, the lifting device 3 includes a crossbeam 302 fixedly installed on both sides of the base plate 301, a climbing wheel 303 rotatably installed on the crossbeam 302 and raised and lowered on the gantry frame 1, a first motor 304 that drives the climbing wheel 303 to rise and fall, and a toggle device 4 installed on the crossbeam 302.

[0034] Specifically, two crossbeams 302 are located on both sides of the base plate 301 and close to the two longitudinal beams of the gantry frame 1. The two longitudinal beams of the gantry frame 1 are vertically equipped with rails 305. The climbing wheels 303 move up and down along the rails 305. The first motor 304 can drive the climbing wheels 303 to rotate. This arrangement realizes the reciprocating lifting of the lifting device 3, thereby moving the stone slabs to a stackable position, that is, the top of the top stone slab on the storage platform 2, which facilitates the stacking of the stone slabs. The actuating device 4 can move laterally on the crossbeams 302. When the base plate 301 moves to the position above the top stone slab, the actuating device 4 can pull the stone slabs onto the top stone slab, thereby realizing the stacking of the stone slabs.

[0035] As a preferred option, such as Figure 2 and Figure 4 As shown, in this embodiment, a roller shaft 306 is rotatably mounted on the top of the gantry frame 1. A motor is mounted on the top of the gantry frame 1 to drive the roller shaft 306 to rotate. Pulleys 307 are fixedly mounted on both ends of the roller shaft 306. A synchronous belt 308 is meshed on the pulleys 307. One end of the synchronous belt 308 is fixedly mounted on the crossbeam 302, and a counterweight 309 is mounted on the other end.

[0036] It should be noted that the roller 306 and the gantry frame 1 are connected by bearings. The motor drives the roller 306 to rotate, and the pulley 307 follows the rotation of the roller 306, thereby driving the synchronous belt 308 to lift the crossbeam 302. The pulley 307 and the synchronous belt 308 can also be replaced with chain sprockets, as long as they can drive the base plate 301 to lift. The purpose of the counterweight 309 is to offset the self-weight of the crossbeam 302 and the base plate 301, reduce the output torque of the motor, and improve the stability of the crossbeam 302 when lifting. At least three climbing wheels 303 are set on the crossbeam 302, respectively located on the three exposed sides of the track 305. This arrangement can improve the stability of the crossbeam 302 when lifting.

[0037] As a preferred implementation method, such as Figure 5 and Figure 6 As shown, the actuating device 4 in this embodiment includes a guide rail 401 fixedly mounted on a crossbeam 302, a support frame 402 that reciprocates on the guide rail 401, a lever 403 spanning the support frame 402, and a roller 404 rotatably mounted on the support frame 402. The roller 404 is located on the upper part of the guide rail 401 and rotates along the guide rail 401.

[0038] Specifically, the guide rail 401 and the crossbeam 302 are arranged horizontally along their length directions to ensure that the support frame 402 can move back and forth between the cutting equipment and the storage platform 2. Rollers 404 are respectively installed on both sides of the bottom of the support frame 402. The rollers 404 abut against the guide rail 401 to ensure that the support frame 402 can move on the guide rail 401. A second motor 405 is installed on the support frame 402 to drive the rollers 404 to rotate. A transmission shaft can be added between the two rollers 404 to ensure that the two legs of the support frame 402 are subjected to the same driving force.

[0039] In addition, the lever 403 is raised and lowered on the support frame 402. After the support frame 402 moves to the cutting equipment, the lever 403 descends to the rear of the stone slab, and then the support frame 402 moves in the opposite direction. This arrangement ensures that the lever 403 can pull the stone slab onto the bottom plate 301. The side of the bottom plate 301 facing the cutting equipment has a thinner wall thickness, and the thinner side is attached to the cutting equipment to ensure that the stone slab can be moved directly onto the bottom plate 301.

[0040] As a preferred option, such as Figure 7 As shown, in this embodiment, a sliding frame 406 is raised and lowered on the support frame 402, and a lever 403 is fixedly mounted on the sliding frame 406. A climbing wheel 303 and a track 305, identical to those on the lifting device 3, are provided between the sliding frame 406 and the support frame 402. A threaded sleeve 407 is fixedly mounted on the sliding frame 406, and a lead screw 408, which is screwed to the threaded sleeve 407, is rotatably mounted on the support frame 402. A third motor 409, which drives the lead screw 408 to rotate, is fixedly mounted on the support frame 402.

[0041] It should be noted that the sliding frame 406 is partially covered by the support frame 402. The track 305 on the support frame 402 is vertically arranged on both sides. The climbing wheels 303 are rotatably arranged on both sides inside the sliding frame 406. This arrangement ensures that the climbing wheels 303 can rise and fall along the track 305. The sliding frame 406 is U-shaped. The lever 403 is fixedly installed in the middle of the transverse beam of the sliding frame 406. When the support frame 402 moves to the cutting equipment, the sliding frame 406 descends until the lever 403 stops at the rear of the stone slab. Then the support frame 402 moves in the opposite direction to complete the movement of the stone slab. After moving to one side of the storage platform 2, the lifting device 3 rises and rises to the top stone slab. The lever 403 moves the stone slab onto the top stone slab, thus completing the stacking. The two ends of the lead screw 408 are rotatably arranged on the support frame 402 through bearings. The third motor 409 drives the lead screw 408 to rotate. The lead screw 408 and the threaded sleeve 407 are screwed together. This arrangement enables the lead screw 408 to drive the sliding frame 406 to rise and fall when it rotates.

[0042] In this embodiment, the stone slab lifting and stacking equipment integrates the gantry frame 1, storage platform 2, lifting device 3, and actuating device 4. Horizontal transfer, vertical lifting, and layer-by-layer stacking are directly completed at the cutting equipment's outlet, significantly reducing manual handling. The crossbeam 302, climbing wheels 303, and longitudinal beam track 305 work together to ensure the base plate 301 can precisely connect with the cutting equipment and storage platform 2 at different heights, improving cycle time matching. The roller 306, pulley 307, synchronous belt 308, and counterweight 309 form a balanced lifting system, reducing motor load and improving lifting stability. The guide rail 401, support frame 402, liftable lever 403, and lead screw 408 with lead sleeve 407 work together to achieve precise stone slab actuation and height-adaptive stacking, improving stacking accuracy and operational safety.

[0043] The above description is only a preferred 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.
