Description

Technical Field

[0001] This invention relates to the field of stacking machine technology, specifically a walking stacking machine. Background Technology

[0002] As a mainstream building material that is energy-saving and environmentally friendly, non-fired bricks require the carrier plates to be repeatedly recycled during their production process. The efficiency of handling and stacking the carrier plates directly determines the capacity of the entire production line.

[0003] In traditional brick production, the brick-carrying slabs after pressing and forming rely entirely on manual handling and stacking. This not only involves high labor intensity, numerous safety hazards, and a high rate of brick breakage, but also suffers from the fatal flaw of low efficiency. A skilled worker can only handle 2-3 slabs per minute, which cannot match the production pace of 4-6 bricks per minute of a high-speed brick-making machine. This often leads to slab accumulation, forcing the brick-making machine to slow down or stop, and the designed capacity of the equipment cannot be fully utilized.

[0004] While existing automated stacking equipment can replace manual labor, it generally suffers from the technical limitation of being able to pick up only one load plate at a time. Its operating cycle cannot keep up with the production speed of high-speed brick-making machines, and the load plate handling process remains a bottleneck in production line capacity. Some stacking equipment using robotic arms are complex in structure, expensive, and have high maintenance costs, making them difficult to promote and apply in small and medium-sized brick-making enterprises.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a walking stacking machine that can effectively solve the aforementioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A walking stacking machine includes a transverse guide rail, a walking frame, a lifting frame, and a clamping mechanism. The walking frame is slidably connected to the transverse guide rail, and the lifting frame is slidably connected to the walking frame. The clamping mechanism is mounted on the lifting frame and includes front and rear clamping assemblies on the front and rear sides of the lifting frame, left and right clamping assemblies on the left and right sides of the lifting frame, and a middle clamping assembly in the middle of the lifting frame. The middle clamping assembly includes a first swing arm, a second swing arm, a connecting rod, a first cylinder, and a rotating shaft. The two rotating shafts are symmetrically arranged on the left and right sides and are rotatably connected to the lifting frame. The upper ends of the two rotating shafts are respectively connected to the middle of the first swing arm and the end of the second swing arm. The front ends of the first swing arm and the second swing arm are respectively hinged to the two ends of the connecting rod. The first cylinder is hinged to the lifting frame, and the piston rod of the first cylinder is hinged to the end of the first swing arm.

The piston rod of the second cylinder is hinged to the upper end of the first front connecting plate. The lower end of the first front connecting plate is sleeved on the first drive shaft.

[0010] Furthermore, the left and right chuck assemblies include a second drive shaft, a second gripper, a second front connecting plate, a second rear connecting plate, and a third cylinder. The two ends of the second drive shaft are rotatably connected to the lifting frame. The upper end of the second gripper is sleeved on the second drive shaft. The second rear connecting plate is fixedly connected to the lifting frame. The rear end of the third cylinder is hinged to the second rear connecting plate. The piston rod of the third cylinder is hinged to the upper end of the second front connecting plate. The lower end of the second front connecting plate is sleeved on the second drive shaft.

[0011] Furthermore, the traveling frame is equipped with a lifting drive mechanism, which includes a first motor, a lifting drive shaft, a lifting drive sprocket, a lifting transmission sprocket, a first chain, and a first guide sprocket. The lifting drive shaft is horizontally arranged, and its two ends are rotatably connected to the traveling frame. The lifting drive sprocket is sleeved on one end of the lifting drive shaft, and the lifting transmission sprocket is sleeved on both ends of the lifting drive shaft. The first guide sprocket is rotatably connected to the traveling frame. The first motor is fixedly connected to the traveling frame, and the output shaft of the first motor is connected to the lifting drive sprocket through a sprocket mechanism. The first chain is wound around the lifting transmission sprocket and the first guide sprocket, and its two ends are respectively fixed to the lifting frame.

[0012] Furthermore, the lifting frame is equipped with lifting guide wheels, and the traveling frame is equipped with vertical guide rails that cooperate with the lifting guide wheels.

[0013] Furthermore, the traveling frame and the transverse guide rail are slidably connected through a traveling drive mechanism. The traveling drive mechanism includes a second motor, a traveling drive shaft, a traveling drive sprocket, a traveling transmission sprocket, a second chain, a second guide sprocket, a traveling driven shaft, and traveling guide wheels. The second motor is mounted on the traveling frame, and both ends of the traveling drive shaft are rotatably connected to the traveling frame. The traveling drive sprocket is sleeved on one end of the traveling drive shaft, and the traveling transmission sprocket is sleeved on both ends of the traveling drive shaft. The output shaft of the second motor is connected to the traveling drive sprocket through a sprocket mechanism. The traveling driven shaft is rotatably connected to the lower end of the traveling frame. The traveling guide wheels and the second guide sprocket are sleeved on the traveling driven shaft, and the second chain is wound around the traveling transmission sprocket and the second guide sprocket. The traveling guide wheels cooperate with the transverse guide rail.

[0014] This invention provides a walking stacking machine. It has the following beneficial effects:

[0015] 1. This invention significantly improves the efficiency of carrier plate handling, completely eliminating production line capacity bottlenecks. Through the coordinated operation of the intermediate chuck assembly and the front, rear, left, and right chuck assemblies, this invention achieves the core function of simultaneously clamping two carrier plates in a single operation, directly doubling the carrier plate handling efficiency compared to existing single-carrier plate stacking machines. This invention can fully keep up with the production speed of high-speed brick making machines, completely solving the long-standing problem of carrier plate handling restricting production line capacity and fully releasing the designed capacity of the brick making machine. Simultaneously, a single machine can completely replace the workload of multiple workers, significantly reducing labor costs for enterprises.

[0016] 2. This invention employs a full-bottom multi-point support clamping structure, ensuring stable and reliable clamping without damaging the carrier plate. Existing automated stacking machines mostly use side clamping, which inherently suffers from difficulty in controlling clamping force: insufficient force can cause the carrier plate to slip, while excessive force can damage softer materials such as wood and plastic. This invention abandons the side clamping approach, adopting a full-bottom support clamping system with multiple support points evenly distributed on the bottom of the two carrier plates. This structure does not exert any lateral pressure on the carrier plate, fundamentally eliminating the possibility of damage. Simultaneously, multi-point support ensures even force distribution on the carrier plate, maintaining stable clamping even with slight deformation. It prevents tilting, shaking, or falling during lifting and movement, significantly improving clamping reliability.

[0017] 3. The intermediate chuck of this invention adopts a single-cylinder connecting rod synchronization mechanism, which has a simple structure and good synchronization of action. The intermediate chuck assembly adopts a clever design of a single-cylinder driven connecting rod synchronization mechanism. Only one first cylinder drives the first swing arm to swing, and then the connecting rod drives the second swing arm to rotate synchronously, so that the two rotating shafts rotate synchronously at the same angle. Compared with the solution of using two independent cylinders to drive the two rotating shafts respectively, this design not only ensures the absolute synchronization of the action of the two support rods, avoiding the tilting of the material plate caused by asynchronous action, but also reduces the complexity of the drive components and air circuit system, reducing the manufacturing cost of the equipment and the difficulty of later maintenance.

[0018] 4. The invention features a simple and compact overall structure, with a modular design that facilitates maintenance and reduces costs. The equipment has a simple and compact overall structure, employing a modular design divided into three independent functional modules: a clamping mechanism, a lifting drive mechanism, and a walking drive mechanism. Assembly and debugging are simple and convenient. When a component malfunctions, the corresponding module can be disassembled and replaced individually without disassembling the entire equipment, significantly reducing maintenance downtime. Furthermore, the motors, sprockets, chains, cylinders, bearings, and other components used in the equipment are all standard parts, making procurement convenient and cost-effective, greatly reducing manufacturing and maintenance costs. This makes it particularly suitable for widespread application in small and medium-sized brick-making enterprises.

[0019] 5. This invention boasts high operational safety, effectively ensuring production safety. The equipment achieves fully automated operation of pallet handling and stacking, completely replacing manual heavy physical labor. This avoids accidents caused by pallets slipping during manual handling and occupational diseases such as lumbar muscle strain caused by long-term heavy physical labor. Furthermore, due to the multi-point bottom support structure, the pallets will not slip during clamping and transportation. Even in the event of air pressure fluctuations or minor malfunctions in a single cylinder, other support points can still reliably support the pallets, effectively preventing equipment damage and personal injury accidents caused by pallets falling, thus improving the overall safety level of the production line.

Detailed Implementation

[0030] The technical solutions in 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.

[0031] Please see the appendix Figure 1 - Appendix Figure 9 This invention provides a walking stacking machine, including a transverse guide rail 11, a walking frame 12, a lifting frame 13, and a clamping mechanism. The walking frame 12 is slidably connected to the transverse guide rail 11, and the lifting frame 13 is slidably connected to the walking frame 12. The clamping mechanism is installed on the lifting frame 13 and includes front and rear clamping assemblies on the front and rear sides of the lifting frame 13, left and right clamping assemblies on the left and right sides of the lifting frame 13, and a middle clamping assembly in the middle of the lifting frame 13.

[0032] In this embodiment, the intermediate chuck assembly includes a first swing arm 21, a second swing arm 22, a connecting rod 23, a first cylinder 24, and a rotating shaft 25. The two rotating shafts 25 are symmetrically arranged left and right, and are rotatably connected to the lifting frame 13. Specifically, the upper end of the rotating shaft 25 is rotatably connected to the lifting frame 13 via a bearing, and the lifting frame 13 is provided with a mounting rod 131 extending in the left and right direction. The mounting rod 131 is provided with a first bearing seat, and the middle part of the rotating shaft 25 is rotatably connected to the first bearing seat. This ensures that the rotating shaft 25 rotates more smoothly. The upper ends of the two rotating shafts 25 are respectively connected to the middle part of the first swing arm 21 and the end of the second swing arm 22. Specifically, the upper ends of the two rotating shafts 25 are connected to the corresponding first swing arm 21 and second swing arm 22 via flat keys, and the upper end of the rotating shaft 25 is fitted with a shaft elastic retaining ring. The first swing arm 21 and the second swing arm 22 are fixed to the rotating shaft 25 by elastic retaining rings. During rotation, the first swing arm 21 and the second swing arm 22 drive the two rotating shafts 25 to rotate around their axes via flat keys. The front ends of the first swing arm 21 and the second swing arm 22 are hinged to the two ends of the connecting rod 23, respectively. The first cylinder 24 is hinged to the lifting frame 13, and the piston rod of the first cylinder 24 is hinged to the end of the first swing arm 21. The lower end of the rotating shaft 25 is provided with a lower bushing 251, and the side wall of the lower bushing 251 is symmetrically provided with support rods 252. With the above structure, in standby mode, the two support rods 252 on the lower bushing 251 are distributed in the left-right direction. When gripping the loading plate, the gripping mechanism is driven to descend to the lower end of the loading plate by a lifting drive mechanism such as a cylinder or sprocket. Then, the first cylinder 24 drives the first swing arm 21 to rotate and swing. When the first swing arm 21 rotates, it drives the second swing arm 22 to rotate synchronously through the connecting rod 23, thereby driving the two rotating shafts 25 to rotate 90 degrees synchronously. At this time, the support rod 252 on the lower bushing 251 rotates 90 degrees and is distributed along the front and rear direction of the lifting frame 13, thereby supporting the lower end of the loading plate on the inner side on both sides. When the lifting frame 13 rises, it supports the loading plate.

[0033] In this embodiment, the front and rear chuck assemblies include a first drive shaft 31, a first gripper 32, a first front connecting plate 33, a first rear connecting plate 34, and a second cylinder 35. The lifting frame 13 is provided with several second bearing seats. The two ends of the first drive shaft 31 are rotatably connected to the second bearing seats via bearings. The upper end of the first gripper 32 is sleeved on the first drive shaft 31. Specifically, each set of front and rear chuck assemblies is provided with three first grippers 32 and two second cylinders 35. The first rear connecting plate 34 is fixedly connected to the lifting frame 13. The rear end of the second cylinder 35 is hinged to the first rear connecting plate 34, and the piston rod of the second cylinder 35 is hinged to the upper end of the first front connecting plate 33. The lower end of the first front connecting plate 33 is sleeved on the first drive shaft 31. With the above structure, the first drive shaft 31 can be driven to rotate by the second cylinder 35, thereby causing the first gripper 32 to swing around the first drive shaft 31, so that the lower end of the first gripper 32 can approach or move away from the bottom of the carrier plate. When the lower end of the first gripper 32 approaches the carrier plate, the lower end of the first gripper 32 can clamp the lower end of the outer side of the carrier plate.

[0034] In this embodiment, the left and right chuck assemblies include a second drive shaft 41, a second gripper 42, a second front connecting plate 43, a second rear connecting plate 44, and a third cylinder 45. Both ends of the second drive shaft 41 are rotatably connected to the second bearing seat via bearings. The upper end of the second gripper 42 is sleeved on the second drive shaft 41. Specifically, each set of left and right chuck assemblies is provided with two second grippers 42 and one third cylinder 45. The second rear connecting plate 44 is fixedly connected to the lifting frame 13. The rear end of the third cylinder 45 is hinged to the second rear connecting plate 44, and the piston rod of the third cylinder 45 is hinged to the upper end of the second front connecting plate 43. The lower end of the second front connecting plate 43 is sleeved on the second drive shaft 41. With the above structure, the second drive shaft 41 can be driven to rotate by the third cylinder 45, thereby causing the second gripper 42 to swing around the second drive shaft 41, so that the lower end of the second gripper 42 can approach or move away from the bottom of the carrier plate. When the lower end of the second gripper 42 approaches the carrier plate, the lower end of the second gripper 42 can clamp the lower ends of the left and right sides of the carrier plate.

[0035] Working principle of the clamping mechanism: When in standby mode, the piston rod of the first cylinder 24 is in a retracted state. At this time, the support rod 252 on the lower bushing 251 is distributed along the left and right directions of the lifting frame 13. The piston rods of the second cylinder 35 and the third cylinder 45 are also in a retracted state, causing the lower ends of the first gripper 32 and the second gripper 42 to maintain an outward swinging state. When clamping the material plate, the two sets of material plates are conveyed to the area below the lifting frame 13 through the feeding mechanism. The lifting frame 13 is driven to descend by the lifting mechanism, causing the support rod 252 to move below the material plate. Then, the piston rod of the first cylinder 24 extends outward, driving the first swing arm 21 and the second swing arm 22 to rotate, thereby causing the rotating shafts 25 on both sides to rotate 90 degrees synchronously, so that the support rod 252 rotates to below the material carrier plate. Afterward, the piston rods of the second cylinder 35 and the third cylinder 45 also extend outward at the same time, driving the first gripper 32 and the second gripper 42 to swing, so that the lower ends of the first gripper 32 and the second gripper 42 swing to below the material carrier plate. Finally, the lifting drive mechanism drives the lifting frame 13 to rise, and the two sets of material carrier plates are clamped together and moved upward by the support rod 252, the first gripper 32 and the second gripper 42. Then, the horizontal drive mechanism drives the lifting frame 13 to move to the storage position to store the material carrier plates.

[0036] In this embodiment, the lifting drive mechanism includes a first motor 51, a lifting drive shaft 52, a lifting drive sprocket 53, a lifting transmission sprocket 54, a first chain 55, and a first guide sprocket 56. The lifting drive shaft 52 is horizontally arranged, and both ends of the lifting drive shaft 52 are rotatably connected to the traveling frame 12. Specifically, the traveling frame 12 is provided with lifting bearing seats, and both ends of the lifting drive shaft 52 are respectively connected to the lifting bearing seats on both sides. The lifting drive sprocket 53 is sleeved on one end of the lifting drive shaft 52, and the lifting transmission sprocket 54 is sleeved on both ends of the lifting drive shaft 52. The first guide sprocket 56 is rotatably connected to the traveling frame 12, and the first guide sprocket 56 is symmetrically arranged on the left and right sides of the traveling frame 12, and is correspondingly arranged below the lifting transmission sprocket 54. The first motor 51 is fixedly connected to the traveling frame 12. The output shaft of the first motor 51 is connected to the lifting drive sprocket 53 through a sprocket mechanism. The first chain 55 is wound around the lifting transmission sprocket 54 and the first guide sprocket 56, and both ends of the first chain 55 are fixed to the lifting frame 13. With the above structure, the first motor 51 drives the lifting drive shaft 52 to rotate through the lifting drive sprocket 53, thereby driving the lifting transmission sprockets 54 on both sides to rotate. When the lifting transmission sprockets 54 rotate, they can drive the first chain 55 to move, thereby pulling the lifting frame 13 to perform lifting and lowering movements.

[0037] In this embodiment, to further improve the stability of the lifting frame 13, the lifting frame 13 is provided with lifting guide wheels 132, and the traveling frame 12 is provided with vertical guide rails 121 that cooperate with the lifting guide wheels 132. During the lifting movement of the lifting frame 13, the lifting guide wheels 132 can roll and cooperate with the vertical guide rails 121, thereby providing stable guidance for the movement of the lifting frame 13.

[0038] In this embodiment, in order to drive the traveling frame 12 to move horizontally back and forth, a transverse guide rail 11 is also included. The traveling frame 12 and the transverse guide rail 11 are slidably connected through a traveling drive mechanism. The traveling drive mechanism includes a second motor 61, a traveling drive shaft 62, a traveling drive sprocket 63, a traveling transmission sprocket 64, a second chain 65, a second guide sprocket 66, a traveling driven shaft 67, and a traveling guide wheel 68. The second motor 61 is mounted on the traveling frame 12. The two ends of the traveling drive shaft 62 are rotatably connected to the traveling frame 12. The traveling drive sprocket 63 is sleeved on one end of the traveling drive shaft 62, and the traveling transmission sprocket 64 is sleeved on both ends of the traveling drive shaft 62. The output shaft of the second motor 61 is connected to the traveling drive sprocket 63 through a sprocket mechanism. The traveling driven shaft 67 is rotatably connected to the lower end of the traveling frame 12. Specifically, the traveling driven shaft 67 is located at the lower rear end of the traveling frame 12, and the lower front end of the traveling frame 12 is also rotatably provided with a cooperating guide wheel that cooperates with the transverse guide rail 11. The traveling guide wheel 68 and the second guide sprocket 66 are mounted on the traveling driven shaft 67. The second chain 65 is wound around the traveling transmission sprocket 64 and the second guide sprocket 66. The traveling guide wheel 68 cooperates with the transverse guide rail 11. With the above structure, the traveling drive shaft 62 is driven to rotate by the second motor 61. The traveling drive shaft 62 drives the second chain 65 to move through the traveling transmission sprocket 64, which in turn drives the second guide sprocket 66 and the traveling driven shaft 67 to rotate. In this way, the traveling guide wheel 68 can be driven to rotate, so that the traveling frame 12 can move laterally on the transverse guide rail 11.
