Description

Technical Field

[0001] This invention belongs to the field of stacking technology, specifically referring to a stacker machine for stacking. Background Technology

[0002] During the efficient operation of the production line, various raw materials, partially processed semi-finished products, and finished products all need to be orderly removed from the production line after completing their respective production stages and securely stacked on specially designed pallets. The main purpose of this is to facilitate the rapid transfer of the neatly stacked goods on the pallets using forklifts, a convenient handling tool, and to accurately stack and place them in designated areas.

[0003] The existing stacker cranes used for stacking currently have the following problems:

[0004] Existing stacker cranes for stacking do not have the ability to adjust the pallet protection height to match the stacking height of goods, resulting in limited stacking height on pallets and reduced utilization efficiency of vertical space in warehouses. Furthermore, traditional stacker cranes for stacking do not have the ability to monitor the stacking height of goods on pallets, leading to a mismatch between protection height and goods height. This can easily cause tipping during forklift transport. Therefore, they cannot meet the current usage requirements for stacker cranes for stacking. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this solution provides a stacker crane for stacking that can adjust the pallet protection height according to the stacking height of goods and monitor the stacking quantity of goods on the pallet.

[0006] The technical solution adopted in this solution is as follows: This solution proposes a stacker crane for stacking, including a transport platform, a stacking platform, a stacking pallet, a gas-collecting gripping mechanism, and a gas-protected stacking mechanism. The stacking platform is located on one side wall of the transport platform, and the stacking pallet is attached to the upper wall of the stacking platform. The gas-collecting gripping mechanism includes a longitudinal component, a vertical component, and a gripping component. The longitudinal component is located on the upper wall of the transport platform, the vertical component is located on the upper wall of the longitudinal component, and the gripping component is located on the vertical component. The gas-protected stacking mechanism includes a magnetic pull component, an air extraction component, a guardrail component, and an air supply component. The magnetic pull component is located on the upper wall of the stacking platform near the transport platform, the air extraction component is located inside the magnetic pull component, the guardrail component is located on the upper wall of the stacking platform on both sides of the stacking pallet, and the air supply component is located at the end of the stacking platform near the guardrail component.

[0007] As a further preferred embodiment of the present invention, the longitudinal component includes a sliding column, a rack, a longitudinal motor, and a drive gear. The sliding column is slidably mounted on the upper wall of the transport platform, the rack is located on one side of the transport platform, the longitudinal motor is located on the side of the sliding column near the transport platform, and the drive gear is located at the power end of the longitudinal motor and meshes with the rack. The vertical component includes a threaded rod, a lifting frame, and a vertical motor. The threaded rod is rotatably mounted at the end of the sliding column away from the transport platform. The lifting frame is located between the sliding column and the threaded rod, and is slidably connected to the sliding column and threadedly connected to the threaded rod. The vertical motor is located on the upper wall of the sliding column, and the power end of the vertical motor passes through the sliding column and is fixedly connected to the threaded rod. The gripping component includes gripping claws and gripping cylinders. The gripping cylinders are symmetrically mounted on the upper wall of the lifting frame at the end away from the threaded rod. The gripping claws are hinged in pairs on both sides of the lifting frame, and the power end of the gripping cylinder is hinged to the upper wall of the gripping claw.

[0008] In use, the conveyor platform and stacking platform are fixedly installed at one end of the production line where materials are unloaded. The conveyor platform is located on one side of the production line, and the stacking platform is located on the ground at the end of the production line. The longitudinal motor drives the drive gear to rotate, and the rotation of the drive gear moves along the rack, causing the sliding column to slide along the upper wall of the conveyor platform. The sliding column, through the lifting frame, drives the gripper to reach above the goods coming off the production line. The vertical component's power end drives the threaded rod to rotate, and the rotation of the threaded rod causes the lifting frame to slide and descend along the side wall of the sliding column. The gripping cylinder's power end shortens, causing the gripper to move in the opposite direction. After the gripper descends and wraps the goods, the gripping cylinder's power end shortens, causing... The gripping claws move relative to each other, rotating around the lifting frame to grab the goods. Then, the power end of the vertical component drives the threaded rod to reverse, which in turn drives the lifting frame to rise. The lifting frame, through the gripping claws, carries the goods away from the production line. The power end of the longitudinal motor reverses, driving the drive gear to roll along the rack, which in turn moves the sliding column closer to the side of the stacking pallet. After the sliding column carries the goods to the top of the stacking pallet, the vertical component drives the lifting frame to descend closer to the upper wall of the stacking pallet. The power end of the gripping cylinder shortens, driving the gripping claws to move in opposite directions. The goods between the gripping claws fall onto the upper wall of the stacking pallet. The above actions are repeated to complete the stacking operation of the goods.

[0009] Preferably, the magnetic pull assembly includes an air extraction cylinder, a U-shaped rod, and a pull magnet. The air extraction cylinder is located on the upper wall of the stacking platform near the transport platform. The U-shaped rod is located on the side of the sliding column near the transport platform, with the end of the U-shaped rod away from the sliding column extending into the air extraction cylinder. The pull magnet is located on the side wall of the U-shaped rod inside the air extraction cylinder. The air extraction assembly includes an air extraction spring, an air extraction magnetic plate, a one-way valve, and a distance sensor. The air extraction spring is located on the inner wall of the air extraction cylinder near the stacking platform. The air extraction magnetic plate is slidably located on the inner wall of the air extraction cylinder and connected to the end of the air extraction spring away from the stacking platform. The one-way valve is located on the side of the air extraction cylinder near the stacking platform. The distance sensor is located on the side of the air extraction magnetic plate away from the air extraction spring. The guardrail assembly includes a U-shaped box, fixing bolts, a one-way pipe, an electric exhaust valve, a protective sleeve, and a guard rod. The U-shaped box is fitted to the stacking pallet. On the upper walls of the stacking platforms on both sides, the fixing bolts pass through the U-shaped box and are threadedly connected to it. The one-way pipe is connected to the upper wall of the U-shaped box, and the electric exhaust valve is connected to the upper wall of the U-shaped box on one side of the one-way pipe. The protective sleeves are symmetrically arranged on the upper walls of both ends of the U-shaped box and are connected to it. The protective rod is slidably arranged on the inner wall of the protective sleeve. The air supply assembly includes an air supply pipe, a spring tube, a docking electromagnet, an electric air inlet valve, and a closing magnet. The air supply pipe passes through the transport platform and the stacking platform and is connected to the bottom wall of the exhaust cylinder near the one-way valve. The spring tube is connected to the upper wall of the air supply pipe below the one-way pipe. The docking electromagnet is located at the end of the spring tube near the air supply pipe. The closing magnet is located at the end of the air supply pipe near the docking electromagnet. The docking electromagnet and the closing magnet are arranged opposite to each other. The electric air inlet valve is connected to the end of the air supply pipe near the stacking platform.

[0010] During use, the more times the sliding column reciprocates, the higher the stacking height of the goods. To ensure the safety of the stacked goods during forklift transportation, the sliding column is initially positioned at the end of the transport platform closest to the stacking platform, with the U-shaped rod extending the longest length into the vacuum cylinder. The pull-out magnet and the vacuum magnetic plate are set with opposite poles and the distance between them is at its maximum value, and the vacuum spring is in a compressed state. When it is necessary to grab the goods off the line, the sliding column moves away from the stacking platform, causing the U-shaped rod to be pulled out of the vacuum cylinder. The U-shaped rod causes the pull-out magnet to move away from the vacuum magnetic plate. The pull-out magnet uses the elastic deformation of the vacuum spring to attract the vacuum magnetic plate away from the one-way valve. Under the suction action of the vacuum magnetic plate, external gas enters the vacuum cylinder through the one-way valve. As the deformation length of the vacuum spring increases, the distance between the pull-out magnet and the vacuum magnetic plate decreases. When the distance sensor detects that the distance between the pull-out magnet and the vacuum magnetic plate has reached the preset distance, the stacking of goods stops.

[0011] Specifically, the sliding column sidewall is equipped with a controller.

[0012] The controller is electrically connected to the longitudinal motor, the vertical motor, the gripping cylinder, the ranging sensor, the docking electromagnet, and the electric intake valve.

[0013] The beneficial effects achieved by this solution using the above structure are as follows:

[0014] Compared with existing technologies, this solution combines a gas-collecting gripping mechanism with a gas-protected stacking mechanism. Through the inclusion of longitudinal components, vertical components, gripping components, magnetic pull components, air extraction components, guardrail components, and air supply components, it collects outside air during the stacking process, increasing the protective height of the stacked pallets. This maximizes the utilization of vertical storage space and reduces the likelihood of stacked goods tipping over during forklift transport. Furthermore, it utilizes the air extraction mechanism between the pull magnet and the air extraction plate during the pulling process. The system monitors the distance and automatically determines the stacking height of goods, stopping the grabbing operation. The U-shaped box is pre-fixed to the outer wall of one end of the forklift fork using fixing bolts. Before transporting the pallet, the docking electromagnet and the closing magnet are brought into contact. When the docking electromagnet is energized, it attracts the closing magnet. The electric air intake valve opens, and the air extraction spring elastically resets, squeezing the air inside the air extraction cylinder through the air supply pipe and spring tube into the protective sleeve. The protective rod rises under the push of the air, thus protecting the goods stacked on the upper wall of the pallet. Attached Figure Description

[0033] The magnetic pull assembly 18 includes an air extraction cylinder 19, a U-shaped rod 20, and a pull magnet 21. The air extraction cylinder 19 is located on the upper wall of the stacking platform 2 near the transport platform 1.

The guardrail assembly 27 includes a U-shaped box 28, fixing bolts 29, a one-way pipe 30, an electric exhaust valve 31, a protective sleeve 32, and a guardrail 33. The U-shaped box 28 is fitted to both sides of the stacking pallet 3. On the upper wall of the side stacking platform 2, fixing bolts 29 are installed through and threadedly connected to the U-shaped box 28. A one-way pipe 30 is connected to the upper wall of the U-shaped box 28. An electric exhaust valve 31 is connected to the upper wall of the U-shaped box 28 on one side of the one-way pipe 30. Protective sleeves 32 are symmetrically arranged on the upper walls of both ends of the U-shaped box 28 and are connected to the U-shaped box 28. A protective rod 33 is slidably installed on the inner wall of the protective sleeve 32. The air supply assembly 34 includes an air supply pipe 35, a spring tube 36, a docking electromagnet 37, and an electric air intake valve 38. The air supply pipe 35, which is connected to the conveyor platform 1 and the stacking platform 2, is located on the bottom wall of the air extraction cylinder 19 near the one-way valve 25. The spring tube 36 is connected to the upper wall of the air supply pipe 35 below the one-way tube 30. The docking electromagnet 37 is located on the spring tube 36 near the end of the air supply pipe 35. The closed magnet 39 is located on the end of the air supply pipe 35 near the docking electromagnet 37. The docking electromagnet 37 and the closed magnet 39 are arranged opposite to each other. The electric air intake valve 38 is connected to the end of the air supply pipe 35 near the stacking platform 2.

[0034] The sliding column 6 has a controller 40 on its side wall.

[0035] The controller 40 is electrically connected to the longitudinal motor 8, the vertical motor 13, the gripping cylinder 16, the ranging sensor 26, the docking electromagnet 37, and the electric intake valve 38, respectively.

[0036] In practical use, the U-shaped box 28 is pre-fitted onto the end of the forklift fork plate away from the inner wall, and the fixing bolt 29 is rotated to fit against the fork plate, so that the U-shaped box 28 is fixedly connected to the fork plate. When the forklift fork plate picks up the stacking pallet 3, the stacking pallet 3 is located between the two fork plates, and the U-shaped box 28 is located at the end of the fork plate away from the stacking pallet 3. At this time, the fit width between the U-shaped box 28 and the fork plate plus the fit width between the stacking pallet 3 and the fork plate is equal to the width of the fork plate.

[0037] The conveyor platform 1 and the stacking platform 2 are fixedly set at one end of the production line for unloading. The conveyor platform 1 is set on one side of the production line, and the stacking platform 2 is set on the ground at the end of the production line. The sliding column 6 is placed at the end of the conveyor platform 1 near the stacking platform 2 in the initial state. The U-shaped rod 20 extends into the air extraction cylinder 19 for the longest length. The pull magnet 21 and the air extraction magnetic plate 24 are set with opposite poles and the distance is at the maximum value. The air extraction spring 23 is in the compressed state.

[0038] When goods need to be picked up and taken off the production line, the controller 40 controls the longitudinal motor 8 to start. The power end of the longitudinal motor 8 drives the drive gear 9 to rotate. The rotation of the drive gear 9 causes the sliding column 6 to slide along the upper wall of the conveyor table 1. The sliding column 6 drives the gripper 15 to reach above the goods coming off the production line via the lifting frame 12. The controller 40 controls the vertical component 10 to start. The power end of the vertical component 10 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 causes the lifting frame 12 to slide down along the side wall of the sliding column 6. The controller 40 controls the gripping cylinder 16 to start. The power end of the gripping cylinder 16 extends and causes the gripper 15 to open in opposite directions. After the gripper 15 descends and wraps the goods, the controller 40 controls the power end of the gripping cylinder 16 to shorten and cause the gripper 15 to clamp relatively. The gripper 15 rotates around the lifting frame 12 to grab the goods.

[0039] When the sliding column 6 moves away from the stacking platform 2, it drives the U-shaped rod 20 to be pulled out from the inside of the vacuum cylinder 19. The U-shaped rod 20 drives the pull magnet 21 away from the vacuum magnetic plate 24. The pull magnet 21 uses the elastic deformation of the vacuum spring 23 to attract the vacuum magnetic plate 24 away from the one-way valve 25. Under the suction of the vacuum magnetic plate 24, the outside gas enters the vacuum cylinder 19 through the one-way valve 25. When the U-shaped rod 20 drives the pull magnet 21 away from the vacuum magnetic plate 24, the distance between the pull magnet 21 and the vacuum magnetic plate 24 increases, the magnetic field strength weakens, and the pull magnet 21 is disconnected from the vacuum magnetic plate 24.

[0040] Subsequently, the controller 40 controls the power end of the vertical component 10 to drive the threaded rod 11 to reverse. The reverse rotation of the threaded rod 11 drives the lifting frame 12 to rise. The lifting frame 12 uses the gripping claw 15 to move the goods away from the production line. The controller 40 controls the power end of the longitudinal motor 8 to reverse, driving the drive gear 9 to roll along the rack 7 and move the sliding column 6 to the side closer to the stacking pallet 3. After the sliding column 6 carries the goods to the top of the stacking pallet 3, the vertical component 10 drives the lifting frame 12 to descend and approach the upper wall of the stacking pallet 3. The power end of the gripping cylinder 16 shortens, driving the gripping claw 15 to move in opposite directions. The goods fall between the gripping claws 15 onto the upper wall of the stacking pallet 3. The above actions are repeated to complete the stacking operation of the goods.

[0041] The more times the sliding column 6 reciprocates, the higher the stacking height of the goods. To ensure the safety of the stacked goods during forklift transportation, as the deformation length of the air spring 23 increases, the distance between the pull magnet 21 and the air extraction magnetic plate 24 decreases. When the distance sensor 26 detects that the distance between it and the pull magnet 21 reaches the preset distance, the stacking operation of the goods is stopped.

[0042] The forklift drives the fork plate away from the U-shaped box 28 and inserts it into the U-shaped grooves on both sides of the stacking pallet 3. At this time, the U-shaped box 28 drives the closed magnet 39 to fit with the docking electromagnet 37 through the one-way tube 30. The controller 40 controls the docking electromagnet 37 to be energized. The docking electromagnet 37 generates opposite magnetic poles that attract the closed magnet 39. The spring tube 36 is connected to the one-way tube 30. The controller 40 controls the electric air intake valve 38 to open. The air extraction spring 23 elastically resets and squeezes the air inside the air extraction cylinder 19 into the air supply pipe 35. The air supply pipe 35 delivers air to the one-way tube 30 through the spring tube 36. The one-way tube 30 inflates the protective sleeve 32. The protective rod 33 extends out from the protective sleeve 32 under the push of the gas, thereby increasing the protection height of the goods on the upper wall of the stacking pallet 3. The protection height increases synchronously with the stacking height, forming lateral protection that adapts to the height of the goods, and achieving the purpose of increasing the protection height according to the stacking height of the goods.

[0043] The forklift pulls the stacking pallet 3 to transfer the goods to the storage area. After the stacking pallet 3 supporting the goods is away from the upper wall of the stacking platform 2, the new stacking pallet 3 is placed in the stacking area of ​​the goods on the upper wall of the stacking platform 2. The electric exhaust valve 31 is electrically connected to the forklift cab. The driver controls the electric exhaust valve 31 to open, the air inside the U-shaped box 28 is discharged, and the guard bar 33 descends and slides into the guard sleeve 32, making it convenient for the handling personnel to unload the goods.

[0044] Meanwhile, based on the number of times and the length of the distance change between the ranging end of the ranging sensor 26 and the vacuum magnetic plate 24, the stacking height of goods on the upper wall of the stacking pallet 3 can be limited; the above operation can be repeated for the next use.

[0045] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0046] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
