Technical Field

[0001] This invention relates to the field of unloading machine technology, and specifically to a gantry unloading machine. Background Technology

[0002] The production of stone slabs requires cutting them piece by piece from a whole rock. When cutting vertically from a whole rock, a few centimeters need to be left at the bottom. Because the stone slab is heavy, it is not possible to cut directly to the bottom, otherwise the cut stone slab will easily collapse. Therefore, the last few centimeters of the stone slab need to be cut horizontally by hand to obtain a complete stone slab, which is then transported by cart. However, manual operation has many inconveniences, low efficiency, and is prone to irregular cuts. Summary of the Invention

Detailed Implementation

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] Reference Figures 1 to 9According to an embodiment of the present invention, a gantry unloading machine includes parallel guide rails 1, a movable frame 2 on the guide rails 1, a driving mechanism on the movable frame 2 to move along the guide rails 1, a support frame 3 on the movable frame 2, a first motor 4 on both sides of the upper end of the support frame 3, the output end of the first motor 4 connected to a lead screw 5, the lead screw 5 disposed inside the support frame 3, a movable block 6 disposed between the lead screw 5, the movable block 6 threadedly connected to the lead screw 5, and guide rods 7 penetrating the movable block 6 on both sides inside the support frame 3; a rotatable fixed frame 8 disposed between the movable blocks 6, a plurality of suction cups 9 disposed along the length of one side wall of the fixed frame 8, a through hole disposed in the center of the suction cup 9, the through hole through the guide rods 7. A vacuum generator 10 is connected to a fixed frame 8. A movable block 11 that can move along the length of the fixed frame 8 is installed inside the fixed frame 8. A cutting disc 12 for cutting stone slabs is installed on the movable block 11. First, a whole rock is vertically cut into multiple stone slabs, leaving a few centimeters uncut at the bottom. The rock is placed between parallel guide rails 1. The moving frame 2 is moved by the drive mechanism, so that the support frame 3 and the fixed frame 8 are close to the rock. The movable block 11 is moved to drive the cutting disc 12 to cut the rock. The cut stone slabs are attracted by the suction cups 9 on the side of the fixed frame 8. Then the fixed frame 8 is rotated 90° so that the stone slabs are placed horizontally. The suction cups 9 are released, and the stone slabs can be placed on a trolley for transportation.

[0028] Furthermore, the drive mechanism includes meshing teeth distributed on the outer side of the guide rail 1. The meshing teeth are meshed with a first gear 13. The center of the first gear 13 is connected to a rotating shaft, which is rotatably connected to the movable frame 2. A second gear 14 is fixedly mounted on the upper end of the rotating shaft. The second gear 14 is meshed with a drive gear 15. The drive gear 15 is connected to a second motor 16 via the rotating shaft. The second motor 16 is located on the side wall of the movable frame 2. The second motor 16 drives the drive gear 15 to rotate, thereby causing the first gear 13 and the second gear 14 to rotate. The first gear 13 meshes with the meshing teeth on the guide rail 1, thereby providing power to the movable frame 2, and the movable frame 2 moves.

[0029] Furthermore, a guide groove 17 is provided in the center of the guide rail 1, and fixed shafts are provided at both the front and rear ends of the movable frame 2. Movable wheels 18 are sleeved on the fixed shafts and embedded in the connecting guide groove 17. When the movable frame 2 moves, the movable wheels 18 also move in the guide groove 17. The movable wheels 18 mainly provide support for the movable frame 2 on the guide rail 1.

[0030] Furthermore, positioning shafts 19 are provided on both sides of the fixed frame 8. The positioning shafts 19 are connected to the moving blocks 6, and one end of the positioning shaft 19 passes through the moving blocks 6 and is connected to the output end of the third motor 20. A circular groove 21 is provided at the position where the positioning shaft 19 connects to the moving blocks 6. Two stops 22 at 90° are provided in the groove 21. A locking block 23 is provided on the positioning shaft 19 so that the positioning shaft 19 can rotate 90°. The third motor 20 is used to drive the fixed shaft and the fixed frame 8 to rotate. The locking block 23 restricts the stop 22 at 90°, so that the fixed frame 8 can rotate 90°. The main reason is that the suction cups 9 on the side of the fixed frame 8 hold the stone slab. When the fixed frame 8 rotates 90°, the stone slab is horizontal and finally placed on the trolley for transportation.

[0031] Furthermore, both sides of the lower end of the fixed frame 8 are provided with rails 24, one of which has meshing teeth on its inner side. Each of the four corners of the movable block 11 is provided with a slider 25 fitted on the rail 24. A drive gear 26 that meshes with the meshing teeth is provided between the two sliders 25 located on one side of the meshing teeth. The drive gear 26 is connected to one end of a rotating shaft, and the other end of the rotating shaft passes through the support frame 27 on the movable block 11 and is connected to the output end of the fourth motor 28. The fourth motor 28 drives the drive gear 26 to rotate, and the drive gear 26 meshes with the meshing teeth on the rail 24, thereby providing power to the movable block 11 and driving the movable block 11 to move along the rail 24.

[0032] Furthermore, a fifth motor 29 is also provided on the movable block 11. The output end of the fifth motor 29 is connected to a rotating shaft, which passes through the movable block 11 and is fixedly connected to the cutting disc 12. The fifth motor 29 can drive the cutting disc 12 to rotate and perform horizontal cutting on the stone slab.

[0033] Furthermore, the first motor 4, the second motor 16, the third motor 20, the fourth motor 28, and the fifth motor 29 are all servo motors and are electrically connected to the controller 30 located on the outside of the support frame 3. The vacuum generator 10 is electrically connected to the controller 30. The controller 30 is used to control this unloading machine and to control the suction force of the suction cup 9.

[0034] In practice, a single rock is first vertically cut into multiple slabs, leaving a few centimeters uncut at the bottom. The rock is then placed between parallel guide rails 1. A second motor 16 drives a drive gear 15, which in turn rotates the first gear 13 and the second gear 14. The first gear 13 meshes with the meshing teeth on the guide rails 1, providing power to the moving frame 2. The moving frame 2 moves, bringing the support frame 3 and the fixed frame 8 closer to the rock. Next, a first motor 4 drives a lead screw 5, causing the moving blocks 6 on the lead screw 5 to move up and down. The fixed frame 8 between the moving blocks 6 also moves up and down, adjusting the fixed frame 8 to a suitable height for subsequent cutting. Then, the cutting is performed using a... The air generator 10 creates negative pressure on the suction cup 9, which adheres to the uncut stone slab. The fourth motor 28 then drives the drive gear 26 to rotate, which meshes with the meshing teeth on the connecting track 24, thus providing power to the movable block 11. This causes the movable block 11 to move along the track 24. The fifth motor 29 then drives the cutting disc 12 to rotate, horizontally cutting the stone slab. After cutting, the suction cup 9 still adheres to the stone slab. The third motor 20 then drives the fixed shaft and the fixed frame 8 to rotate, while the clamping block 23 restricts the fixed frame 8 to rotate 90° between the stop blocks 22, thus making the stone slab horizontal. Finally, the suction force of the suction cup 9 is controlled, and the stone slab is placed horizontally on the trolley for transportation.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
