Technical Field

[0001] The present invention relates to the technical field of glass transportation, in particular to a glass transporting device. Background Art

[0002] When transporting glass, a suction cup is used to hold the surface of the glass before it is moved. When the suction cup contacts the glass, air is expelled, creating a negative pressure inside the cup. Under the influence of atmospheric pressure, the cup is attached to the glass. The lower the air pressure inside the cup, the greater the suction cup's grip on the glass. In existing technology, after the suction cup is attached, a lever is used to pull the cup to reduce the pressure inside. After the cup is attached to the glass, the operator is required to manually pull the lever. Inexperienced or negligent operators may miss this lever, resulting in insufficient suction force on the glass and causing accidents. Summary of the Invention

Detailed implementation mode

[0020] To better understand the technical content of the present invention, specific embodiments are provided below, and the present invention will be further described in conjunction with the accompanying drawings.

[0021] See Figures 1 to 3, A glass transfer device, comprising a sleeve 1, a piston 2 and a suction cup 3. The lower end of the sleeve 1 is provided with the suction cup 3. The inner cavity of the suction cup 3 communicates with the sleeve 1. The piston 2 is arranged in the sleeve 1. The piston 2 is connected to a rack 4. When the rack 4 moves up and down, it drives the piston 2 to move synchronously. The rack 4 is always meshed with a first pulley 5. When the rack 4 moves downward, it generates a downward thrust on the first pulley 5, causing the first pulley 5 to move downward. When the rack 4 moves upward, it generates an upward thrust on the first pulley 5, causing the first pulley 5 to move upward. The first pulley 5 is installed on a vertical slider 6, and the vertical slider 6 moves along a direction parallel to the rack 4. Therefore, during use, the rack 4 is always meshed with the first pulley 5. When the rack 4 moves up and down, it will drive the vertical slider 6 to move upward. When the first pulley 5 moves downward, it meshes with an idler pulley 7, and the idler pulley 7 is meshed with a gear 8. Similarly, the gear 8 is meshed with a second pulley 9. The second pulley 9 is installed on an arc-shaped slider 10, and the arc-shaped slider 10 rotates around the gear 8. The gear 8 is always meshed with the second pulley 9. When the gear 8 rotates, it drives the arc-shaped slider 10 to slide and rotate around the gear 8, causing the second pulley 9 to mesh with or disengage from the rack 4. When the arc-shaped slider 10 slides upward, the second pulley 9 meshes with the rack 4. The gear 8 is connected to a torsion spring 11. The transmission ratio of the rack 4 driving the gear 8 to rotate through the first pulley 5 and the idler pulley 7 is greater than 1. The transmission ratio of the gear 8 driving the rack 4 to move through the second pulley 9 is greater than 1. After the rack 4 moves downward and disengages from the first pulley 5, the torsion spring 11 releases elastic potential energy and causes the second pulley 9 to mesh with the rack 4 and the gear 8. Place the suction cup 3 on the glass, and then push the rack 4 downward so that the piston 2 squeezes out the air in the sleeve 1 and the suction cup 3. When the piston 2 presses downward, it drives the rack 4 to move downward. The rack 4 is meshed with the first pulley 5. When the rack 4 moves downward, it drives the first pulley 5 to move downward, causing the first pulley 5 to mesh with the idler pulley 7. At this time, the movement of the rack 4 will drive the gear 8 to rotate, causing the torsion spring 11 to deform and store energy. When the rack 4 moves downward a preset distance, the rack 4 disengages from the first pulley 5, and the rack 4 moves downward to a position where it can mesh with the second pulley 9. Under the action of the torsion spring 11, the gear 8 rotates and drives the second pulley 9 to move, causing the second pulley 9 to mesh with the rack 4, thereby driving the rack 4 to move upward. The rack 4 is connected to the piston 2, so it causes the piston 2 to move upward to increase the negative pressure in the sleeve 1, making the sleeve 1 in a low-pressure state and increasing the adsorption force of the suction cup 3 on the glass.The transmission ratio of the rack 4 driving the gear 8 to rotate through the first pulley 5 and the idler pulley 7 is greater than 1, and the transmission ratio of the gear 8 driving the rack 4 to move through the second pulley 9 is greater than 1, so that when the piston 2 is pressed down, the torsion spring 11 can be driven to store energy with less effort, and a greater driving force can be provided when the elastic potential energy is released, so that the pressure in the sleeve 1 is reduced, and the adsorption capacity of the suction cup 3 for the glass is improved. After the rack 3 is pushed down, the torsion spring 11 is automatically triggered to work, avoiding the forgetting of the staff and reducing the accidents caused by insufficient adsorption force of the suction cup on the glass.

[0022] Preferably, a disc is connected to the top of the rack 4 to facilitate pushing down the rack 4 and the piston 2.

[0023] Specifically, a spring 12 is provided in the sleeve 1, and the spring 12 is used to drive the piston 2 to move away from the suction cup 3, and the piston 2 is driven to move upward and reset by the spring 12, which is convenient for the next pressing.

[0024] Specifically, the rack 4 includes a convex tooth portion 13 and a smooth portion 14. The convex tooth portion 13 is provided with convex teeth meshing with the first pulley 5 and the second pulley 9. The smooth portion 14 is slidably connected to the guide rail 15, and the guide rail 15 is fixedly connected to the sleeve 1. The convex tooth portion 13 of the rack 4 is used for transmitting power, and the smooth portion 14 is used to maintain the stability of the up and down sliding of the rack 4. The smooth portion 14 is slidably connected to the guide rail 15, and the limit block at the bottom of the rack 4 can limit the up and down movement distance of the rack 4. When the rack 4 moves upward to the limit position, the convex tooth portion 13 of the rack 4 still meshes with the first pulley 5, but disengages from the second pulley 9. When the rack 4 moves downward to the limit position, the convex tooth portion 13 of the rack 4 disengages from the first pulley 5, but is in a position where it can mesh with the second pulley 9.

[0025] Specifically, a flexible sealing belt 16 is connected around the piston 2, and the lower end of the sealing belt 16 is connected to the inner wall of the sleeve 1. The sealing performance between the piston 2 and the sleeve 1 is improved to prevent gas leakage.

[0026] Specifically, the piston 2 is provided with a one-way valve 17, and the one-way valve 17 allows gas to be discharged unidirectionally from the sleeve 1. When the piston 2 is pressed down, the gas can be discharged from the one-way valve 17.

[0027] Optionally, the piston 2 is provided with a stop valve 18. The gear 8 is connected with an arc-shaped rod 19. The arc-shaped rod 19 is slidably connected with an arc-shaped sleeve 20. A bellows 21 is arranged inside the arc-shaped sleeve 20. One end of the bellows 21 is connected to the end face of the arc-shaped rod 19, and the other end is connected to the inner wall of the arc-shaped sleeve 20. The arc-shaped sleeve 20 is communicated with a water storage tank 22. The water storage tank 22 is provided with a one-way valve plate 23, and a through hole 24 is arranged on the valve plate. When the gear 8 rotates forward and backward, the arc-shaped rod 19 slides inside the arc-shaped sleeve 20, thereby pushing the liquid inside the arc-shaped sleeve 20 to move into the water storage tank 22 or pumping out the water in the water storage tank 22. When the gear 8 rotates forward to store energy, the water flows into the water storage tank 22, and the water pushes open the one-way valve plate 23. At this time, the cross-section of the water flow channel is large and can flow quickly, so that the gear 8 can rotate quickly after being subjected to a thrust. When the gear 8 rotates backward to release the elastic potential energy, the water flows from the water storage tank 22 into the arc-shaped sleeve 20. The water pushes the one-way valve plate 23 to close the channel of the arc-shaped sleeve 20, and the water can only pass through the through hole 24, increasing the water flow resistance. The arc-shaped rod 19 can only move slowly, making the gear 8 rotate slowly. Therefore, by quickly pressing the piston 2 multiple times, the gear 8 can be rotated to store energy, increasing the elastic force of the torsion spring 11, thereby reducing the pressure inside the sleeve 1 and increasing the adsorption force of the suction cup 3 on the glass.

[0028] Specifically, it further includes a moving vehicle 28, a winch 25, a fixed pulley 26 and a pulling rope 27. A fixed pulley 26 is arranged above the moving vehicle 28. The pulling rope 27 bypasses the fixed pulley 26. One end of the pulling rope 27 is connected to the sleeve 1, and the other end is connected to the winch 25. After the suction cup 3 sucks the glass, the winch 25 is used to wind up the pulling rope 27. The pulling rope 27 bypasses the fixed pulley 26 and then pulls up the sleeve 1, thereby lifting the glass. The lifted glass can be placed on the moving vehicle 28 for easy handling of the glass.

[0029] Specifically, a plurality of vertical partition plates 29 are arranged inside the moving vehicle 28. The glass can be separated, and multiple pieces of glass can be placed on the moving vehicle 28.

[0030] Specifically, buffer pads 30 are arranged on the side and bottom of the partition plate 29 to buffer the glass and prevent the glass from breaking after being impacted.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
