Description

Technical Field

[0001] This invention belongs to the technical field of warehouse stacking, and specifically discloses an anti-collapse stacking machine for automated warehouses. Background Technology

[0002] In the production and warehousing processes of industries such as chemicals, pharmaceuticals, and coatings, the storage and turnover of small-diameter chemical containers (typically 5-50L in capacity, containing solvents, coatings, adhesives, and other chemical products) relies on efficient vertical palletizing technology. Vertical palletizing has become the mainstream method for storing small-diameter chemical containers because it maximizes the use of three-dimensional storage space (compared to horizontal storage, space utilization is increased by 40%-60%). However, it still faces multiple safety and stability issues during palletizing, transportation, and storage, and existing technologies have significant shortcomings.

[0003] Small chemical containers, mostly cylindrical metal or plastic, have smooth surfaces and a relatively high center of gravity (when full, the center of gravity is above half the height of the container). In existing palletizing production lines, conveyors can only initially transport the chemical containers and lack precise positioning mechanisms. When the chemical containers are conveyed to the robotic arm's gripping position, a lateral offset of 5-10mm often occurs due to conveyor vibration. If the robotic arm grasps the offset container according to a preset trajectory, it will cause a deviation in the verticality of the container during palletizing. This initial offset will accumulate after multiple layers (usually 3-5 layers), causing the upper containers to tend to slide along the inclined surface, creating a potential hazard for subsequent collapse. Especially for metal containers, the anti-corrosion coating on their surface is easily worn away by collisions, further reducing the coefficient of friction of the container during palletizing and exacerbating the risk of offset.

[0004] In addition, the existing equipment lacks dynamic protection during transportation. When the stacked chemical tanks are transferred to the storage rack by the elevator, the inertial force of starting and braking will cause the multi-layer tanks to shake relative to each other, which may eventually cause the entire stack to collapse, resulting in chemical leakage (especially for flammable and corrosive chemicals), posing a serious safety hazard.

[0005] Therefore, an anti-collapse stacker crane for automated warehouses is proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the background art, and to propose an anti-collapse stacker crane for automated warehouses, including a frame, an L-shaped stacking platform, a lifting drive device, a conveyor, and a tank. The lifting drive device is installed inside the upper part of one side of the frame, and the conveyor is erected above one side of the L-shaped stacking platform. The L-shaped stacking platform slides on one side of the frame via the lifting drive device. An electric screw drive mechanism is fixedly installed on the outer side of the conveyor, and a fixed shell is slidably provided outside the electric screw drive mechanism. The fixed shell is connected to a second hydraulic cylinder inside. The cross-shaped structure is slidably connected to a fixed shell. Storage cavities are opened on both sides of the cross-shaped structure, and corresponding abutments are connected to the storage cavities via symmetrically arranged telescopic mechanisms. Two L-shaped rods are connected to the outer side of each abutment via corresponding extension mechanisms. A support rod is fixedly installed on the upper surface of the abutment, and L-shaped frames are fixedly installed on both sides of the support rods. Flexible netting is correspondingly installed on both sides of the L-shaped frames and L-shaped rods. A vertical pole is fixedly inserted inside the cross-shaped structure near the center, and multiple sets of positioning components are arranged sequentially on the outer side of the vertical pole.

[0007] In the above technical solution, a tray is further provided above the conveyor, and four sets of tanks are provided, with the four sets of tanks placed on the upper surface of the tray and at the corresponding corners.

[0008] In the above technical solution, the telescopic mechanism further includes a third hydraulic cylinder fixedly installed inside the storage cavity, and the telescopic end of the third hydraulic cylinder is fixedly connected to the outside of the abutment side.

[0009] In the above technical solution, the extension mechanism further includes a bracket fixedly installed on the outside of the seat away from the third hydraulic cylinder. A servo motor is fixedly installed on the inner surface of the bracket. A screw is connected to the output end of the servo motor through a sleeved synchronous belt assembly. The screw rotates and passes through the inside of the support rod. A threaded sleeve is threadedly connected to the outside of the screw. Two L-shaped rods are respectively fixedly installed on both sides of the outside of the threaded sleeve. A bidirectional telescopic rod is installed on the outer surface of the L-shaped rod and the L-shaped frame that are close to each other and near the corner.

[0010] In the above technical solution, positioning buttons are symmetrically installed on both sides of the L-shaped rod and L-shaped frame, and the four corners of the flexible barrier are respectively fitted onto the corresponding positioning buttons on the same side.

[0011] In the above technical solution, further, a fixing frame is installed on both sides of the L-shaped rod, and a first hydraulic cylinder is provided inside the fixing frame. The telescopic ends of the first hydraulic cylinder are jointly installed with an arc-shaped rolling table, and multiple balls are embedded in the inner surface of the arc-shaped rolling table.

[0012] In the above technical solution, further, the multiple sets of positioning components include a retainer that is fixedly sleeved on the outside of the upright, and four infrared positioning rods are fixedly installed on the outside of the retainer.

[0013] In the above technical solution, further, abutment frames are fixedly installed on the outer sides of both ends of the abutment seat, and a rotating shaft is rotatably installed at the end of the abutment frame through a damping sliding sleeve that is fixedly sleeved. A U-shaped block is fixedly sleeved on the outside of the rotating shaft, and an arc-shaped abutment platform is fixedly installed on the outside of the U-shaped block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The L-shaped rod and L-shaped frame are extended by the extension mechanism, and the tension of the flexible barrier is adjusted by the bidirectional telescopic rod to form a four-sided flexible protection structure. During stacking and transportation, the tank is restrained on the outside to prevent the risk of collapse caused by inertial swaying.

[0016] 2. Through the structural design of the arc-shaped abutment and damping sleeve, it provides buffering and adaptive angle adjustment when clamping the tank, adapting to tanks of different diameters and enhancing the stability and adaptability of clamping.

[0017] 3. By setting up an arc-shaped rolling platform and ball bearings, dynamic adjustment is achieved when the can body is slightly tilted, ensuring stacking stability. The first hydraulic cylinder inside the L-shaped rod pushes the arc-shaped rolling platform to extend, and the ball bearings on the inner surface of the rolling platform fit against the outside of the can body. If the can body is slightly tilted during stacking or transportation, the ball bearings can roll along the surface of the can body, and the rolling friction will drive the can body to slowly return to its original position. At the same time, the arc-shaped structure can adapt to the cylindrical contour of the can body, ensuring the contact area between the ball bearings and the can body, avoiding local stress that could cause the can body to deform, and thus correcting the tilt angle of the can body.

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1-10The illustrated automated warehouse anti-collapse stacker crane includes a frame 1, an L-shaped stacking platform 2, a lifting drive device 3, a conveyor 4, and a tank 10. The lifting drive device 3 is installed on the upper part of one side of the frame 1, and the conveyor 4 is mounted on the upper part of one side of the L-shaped stacking platform 2. The L-shaped stacking platform 2 slides on one side of the frame 1 via the lifting drive device 3. An electric screw drive mechanism 6 is fixedly installed on the outer side of the conveyor 4. A fixed shell 13 is slidably installed outside the electric screw drive mechanism 6. A cross 11 is connected inside the fixed shell 13 via a second hydraulic cylinder 12. The cross 11 is slidably connected to the fixed shell 13. Storage cavities 31 are respectively opened on both sides inside the cross 11, and the storage cavities 31 are connected by symmetrically arranged telescopic mechanisms. A base 19 is connected, and two L-shaped rods 7 are connected to one side of the base 19 via corresponding extension mechanisms. A support rod is fixedly installed on the upper surface of the base 19, and L-shaped frames 17 are fixedly installed on both sides of the support rod. Flexible nets 24 are correspondingly installed on both sides of the L-shaped frames 17 and L-shaped rods 7. A vertical pole 22 is fixedly inserted inside the cross 11 near the middle. Multiple sets of positioning components are arranged vertically on the outside of the vertical pole 22. Positioning pins 25 are symmetrically installed on both sides of the L-shaped rods 7 and L-shaped frames 17. The four corners of the flexible net 24 are respectively fitted onto the corresponding positioning pins 25 on the same side. A tray 5 is set above the conveyor 4. Four sets of tanks 10 are set, and the four sets of tanks 10 are placed on the upper surface of the tray 5 and at the corresponding corners.

[0032] In this embodiment, the lifting drive device 3 adopts a drive motor and ball screw structure, and is installed on the upper inside of one side of the upright frame 1 to ensure running accuracy. The conveyor 4 adopts a plate conveyor 4. With the connection of the lifting drive device 3, the vertical lifting and sliding of the L-shaped stacking platform 2 can be realized, which makes it easy to stack in the vertical warehouse. The flexible net 24 is made of high-strength nylon material, and the four corners are hung on the outside of the positioning button post 25 on the same side by corresponding hanging rings to form a protective structure.

[0033] Specifically, during operation, the L-shaped stacking platform 2 is first moved to the stacking area via the lifting drive device 3 and the electric screw drive mechanism 6. Then, the cans 10 are placed on top of the pallet 5. Placing the cans 10 at the four corners of the pallet 5 ensures its balance and improves stacking stability. The crossbar 11 moves to align with the pallet 5, and the second hydraulic cylinder 12 drives the crossbar 11 to descend and cover the pallet 5. Cans 10 are then stacked sequentially on top of each other. After completion, the telescopic mechanisms on both sides push the abutment 19 inward, initially clamping the bottom layer of cans 10 from both sides. Simultaneously, the extension mechanism drives the L-shaped rod 7 to extend upward, working with the fixed L-shaped frame 17 to tension the surrounding flexible netting 24, forming an enclosure. The entire equipment is then lifted and transported to the rack. Positioning components ensure precise alignment. Finally, all actuators release, completing the stacking process. Throughout the entire transport process, the flexible netting 24 constantly restrains the cans 10, preventing them from tipping over due to inertial swaying.

[0034] The telescopic mechanism includes a third hydraulic cylinder 32 fixedly installed inside the storage cavity 31, and the telescopic end of the third hydraulic cylinder 32 is fixedly connected to the outside of one side of the abutment 19.

[0035] In this embodiment, the two third hydraulic cylinders 32 extend synchronously, pushing the two abutments 19 to move in opposite directions along a straight line, which can drive the arc-shaped abutment 9 on the abutment 19 to stick tightly to the outer wall of the tank body 10. When unloading, the third hydraulic cylinders 32 retract synchronously, driving the abutment 19 to detach from the tank body.

[0036] The extension mechanism includes a bracket 18 fixedly installed on the outside of the support seat 19 on the side away from the third hydraulic cylinder 32. A servo motor 28 is fixedly installed on the inner surface of the bracket 18. A screw 14 is connected to the output end of the servo motor 28 through a sleeved synchronous belt assembly 29. The screw 14 is rotatably inserted into the support rod. A threaded sleeve 15 is threadedly connected to the outside of the screw 14. Two L-shaped rods 7 are fixedly installed on both sides of the outside of the threaded sleeve 15. A bidirectional telescopic rod 16 is installed on the outer surface of the L-shaped rods 7 and the L-shaped bracket 17 on the side close to each other and near the corner.

[0037] In this embodiment, when the position of the L-shaped rod 7 needs to be adjusted, the servo motor 28 starts, and its output shaft drives the synchronous belt assembly 29 to rotate. The synchronous belt assembly 29 drives the screw 14 to rotate inside the support rod. Since the screw sleeve 15 is threadedly connected to the screw 14, and the L-shaped rod 7 is fixedly connected to the screw sleeve 15, and the bidirectional telescopic rod 16 guides the L-shaped rod 7, the screw sleeve 15 will move along the axial direction of the screw 14, thereby driving the L-shaped rod 7 to move synchronously, ensuring that the L-shaped rod 7 always moves smoothly along a straight line.

[0038] Specifically, the servo motor 28, in conjunction with the synchronous belt assembly 29, drives the screw 14 to rotate. It features high transmission accuracy and smooth operation, and can precisely control the movement distance of the L-shaped rod 7, ensuring that the frame formed by the L-shaped rod 7 and the L-shaped frame 17 can accurately surround the tank 10, thereby improving the adaptability of the protective structure.

[0039] The L-shaped rod 7 has a fixing frame 23 installed on both sides inside. The fixing frame 23 is equipped with a first hydraulic cylinder 8. The extension and retraction ends of the first hydraulic cylinder 8 are jointly equipped with an arc-shaped rolling table 21. Multiple balls 27 are embedded in the inner surface of the arc-shaped rolling table 21.

[0040] In this embodiment, the arc-shaped rolling table 21 is made of wear-resistant steel plate, and the arc radius is adapted to the outer radius of the common tank body 10. Multiple spherical grooves are opened on the inner surface of the arc-shaped rolling table 21, and the ball 27 is embedded in the spherical groove. The ball 27 can roll freely in the groove, and a retaining ring is set at the opening of the groove to prevent the ball 27 from falling off. This structure is the prior art, so it will not be described in detail.

[0041] Specifically, when the infrared positioning rod 20 detects a slight tilt in the tank 10, the control system sends a signal to activate the first hydraulic cylinder 8 inside the L-shaped rod 7. The telescopic end of the first hydraulic cylinder 8 extends, pushing the arc-shaped rolling platform 21 towards the tank 10 until the balls 27 on the inner surface of the arc-shaped rolling platform 21 contact the outside of the tank 10. Since the balls 27 can roll freely in the spherical groove, when the tank 10 is tilted, the rolling friction between the balls 27 and the surface of the tank 10 will cause the tank 10 to rotate slowly, gradually correcting the tilt angle. At the same time, the arc-shaped structure of the arc-shaped rolling platform 21 matches the cylindrical contour of the tank 10, ensuring that multiple balls 27 contact the tank 10 simultaneously, evenly distributing the force and preventing excessive local stress on the tank 10, which could lead to deformation. After the tank 10 is reset, the telescopic end of the first hydraulic cylinder 8 retracts, causing the arc-shaped rolling platform 21 to reset and disengage from the tank 10.

[0042] It should be emphasized that the position of the arc-shaped rolling table 21 can be adjusted during transportation. When stacking multiple layers of tanks 10, it can be placed on top of the tanks 10. When stacking the bottom layer of tanks 10, it can be detached from the tanks 10.

[0043] Multiple positioning components include a retainer 30 that is fixedly sleeved on the outside of the upright 22, and four infrared positioning rods 20 are fixedly installed on the outside of the retainer 30 respectively;

[0044] In this embodiment, the infrared positioning rod 20 constitutes a non-contact visual positioning structure. The infrared positioning rod 20 is composed of an infrared positioning sensor and a rod body. The infrared beam emitted by it can accurately identify the height of each shelf and the position of the can 10. It can not only guide the robotic arm mechanism to perform precise stacking and picking, but also facilitate the subsequent correction of the curved rolling table 21.

[0045] A retaining frame 26 is fixedly installed on both outer sides of the retaining seat 19. A rotating shaft 33 is rotatably installed at the end of the retaining frame 26 through a damping sleeve 35 that is fixedly connected. A U-shaped block 34 is fixedly connected to the outside of the rotating shaft 33. An arc-shaped retaining platform 9 is fixedly installed on the outside of the U-shaped block 34.

[0046] In this embodiment, the damping sleeve 35 provides a certain resistance when the rotating shaft 33 rotates, so the arc-shaped abutment 9 has the function of adaptive angle adjustment. The arc-shaped abutment 9 can automatically adjust to the best fitting angle after contact to achieve surface contact, which greatly increases the contact area and stability of clamping and avoids excessive pressure or unstable clamping caused by point contact or line contact.

[0047] Specifically, when the third hydraulic cylinder 32 pushes the abutment 19 forward, the arc-shaped abutment 9 contacts the surface of the tank 10 (if the contact surface does not fit with the tank 10, the contact force will overcome the resistance of the damping sleeve 35, forcing the rotating shaft 33 to rotate until the arc surface of the arc-shaped abutment 9 is completely fitted with the outer wall of the tank 10, after which the damping effect can keep it at that angle, providing a stable clamping force).

[0048] It should be noted that this control system uses a PLC controller.

[0049] Working principle: Four sets of tanks 10 are placed at the corresponding corners of the pallet 5 above the conveyor 4. Under the extension and retraction of the second hydraulic cylinder 12, the cross 11 and the upright 22 are erected above the pallet 5. Four infrared positioning rods 20 are fixedly installed by the clamp 30. Multiple sets of these positioning components form a three-dimensional positioning pattern. During the stacking of multiple sets of tanks 10, the infrared positioning rods 20 scan the position of the tanks 10 in real time and feed the signal back to the control system. The control system can drive the robot to stack the tanks in sequence according to the position of the bottom tanks 10. If the infrared positioning rods 20 detect a slight deviation of the tanks 10, the first hydraulic cylinder 8 in the fixing frame 23 inside the L-shaped rod 7 is activated. Its extension end pushes the arc-shaped rolling table 21 to extend towards the tanks 10 until the ball bearings 27 on the inner surface of the arc-shaped rolling table 21 contact the outside of the tanks 10. The ball bearing 27 rolls along the surface of the can 10, and the rolling friction drives the can 10 to slowly return to its original position, correcting the skew angle and ensuring the verticality of the stacking. After the vertical stacking of multiple cans 10 is completed, the third hydraulic cylinder 32 in the internal storage cavity 31 of the cross 11 is activated. The telescopic end of the third hydraulic cylinder 32 pushes the abutment 19 to move towards the can 10 until the abutment frame 26 on the outside of the abutment 19 approaches the can 10. The end of the abutment frame 26 is rotatably mounted on the rotating shaft 33 through the damping sleeve 35. During the movement of the abutment 19, the arc-shaped abutment 9 connected to the external U-shaped block 34 first contacts the surface of the can 10. Due to the damping characteristics of the damping sleeve 35, the rotating shaft 33 can rotate slowly, driving the arc-shaped abutment 9 to adaptively adjust the angle until the arc-shaped abutment 9 is tightly attached to the surface of the can 10, realizing stable clamping of cans 10 of different diameters, while avoiding damage to the can 10 caused by rigid contact.

[0050] Subsequently, the servo motor 28 starts, and its output end drives the screw 14 to rotate inside the support rod through the synchronous belt assembly 29. The screw sleeve 15, which is threadedly connected to the screw 14, moves along the axial direction of the screw 14, thereby driving the L-shaped rods 7 fixed on both sides of the outside of the screw sleeve 15 to move synchronously. Meanwhile, the bidirectional telescopic rod 16 between the L-shaped rod 7 and the L-shaped frame 17 adapts to the expansion and contraction, ensuring the smooth movement of the L-shaped rod 7 until the L-shaped rod 7 and the L-shaped frame 17 form a frame structure surrounding the tank 10. The positioning pins 25 on both sides of the L-shaped rod 7 and the L-shaped frame 17 are respectively fitted to the four corners of the flexible barrier net 24. As the L-shaped rod 7 moves, the flexible barrier net 24 gradually tightens, forming a four-sided flexible protective structure, which constrains the outside of the tank 10 to prevent it from shaking in subsequent operations. Finally, the conveyor 4 and the electric screw drive mechanism 6 move synchronously to transport the stacked tank 10 to the shelf. This device can achieve stable stacking of multiple layers of tank 10. During the stacking and transfer process, the flexible barrier net 24, the arc-shaped support platform 9 and the arc-shaped rolling platform 21 work together to effectively prevent the tank 10 from collapsing due to inertial swaying and tilting.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
