Description

Technical Field

[0001] This utility model relates to the field of automated equipment technology for warehousing and logistics, and in particular to an electric destacking and stacking equipment. Background Technology

[0002] In the field of warehousing and logistics, material crates are tools used by logistics companies to store and turn over materials. Material crates have a certain volume, and as a common storage container in warehousing and logistics, the stacking and unstacking of material crates is an important step.

[0003] Currently, most common de-stacking and stacking machines use a cylinder-driven fork structure for lifting and placing on both sides. However, this method has many drawbacks: (1) complex structure (requires a matching air supply system), resulting in a large space occupation of the equipment; (2) high maintenance cost (cylinders are prone to wear and replacement frequency is high); (3) poor lifting and positioning accuracy (air pressure fluctuations affect stability). Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an electric destacking and stacking frame device.

[0005] This utility model discloses an electric stacking and unstacking device, comprising a main frame, wherein the inner side of the main frame is provided with a vertical guide rail, and further comprising:

[0006] The material frame fork assembly includes two fork mechanisms located on the inner sides of the main frame. The fork mechanisms can slide into the vertical guide rail on the corresponding side. The fork mechanism includes a hook that can extend or retract, which extends to fork the side of the material frame.

[0007] A lifting drive assembly is used to drive the forklift mechanism to move up and down along the guide rail;

[0008] The swing arm drive assembly is connected to the hook via a crank-rocker mechanism and is used to drive the hook to extend or retract.

[0009] An electrical control system is communicatively connected to the lifting drive assembly and the swing arm drive assembly.

[0010] Preferably, the lifting drive assembly includes a lifting motor and a drive shaft. The lifting motor drives the drive shaft to rotate. Both ends of the drive shaft are fixed with gear and sprocket welded components. The gear and sprocket welded components are designed as composite transmission components integrating gears and sprockets. One side of the component meshes with a transmission gear through a gear, and the other side is connected to a reverse drive chain through a sprocket. The first ends of two lifting chains are connected and fixed to both sides of the reverse drive chain. The second ends of the lifting chains are fixed to the forklift mechanism through connectors. The two lifting chains correspond to the forklift mechanisms on both sides, forming a "left-right linkage" transmission structure.

[0011] Preferably, the reverse drive chain is wound in a ring around the sprocket of the gear sprocket welded component. When the drive shaft rotates, the gear sprocket welded component rotates synchronously, driving the sprocket of the gear sprocket welded component to rotate. The upper chain of the reverse drive chain moves towards the lifting motor, and the lower chain moves away from the lifting motor, forming a pulling force in opposite directions. The movement of the reverse drive chain is transmitted to the lifting chains on both sides. The lifting chains on both sides move in opposite directions, thus the lifting chains on both sides are stretched synchronously and in opposite directions, driving the forklift mechanism to lift vertically.

[0012] Preferably, the forklift mechanism is fixed with a guide wheel, which is slidably connected within the vertical guide rail.

[0013] Preferably, the swing arm drive assembly includes a swing arm drive motor, the output shaft of which is fixed to the crank in the crank-rocker mechanism. The crank is connected to one end of the rocker via a rotating joint, and the other end of the rocker is hinged to the swing arm assembly. The end of the swing arm assembly is fixedly connected to the hook for picking up and placing the material frame.

[0014] Preferably, it also includes sensors and limiting devices that can communicate with the electrical control system, the sensors and limiting devices being used to detect and control the position of each component.

[0015] Preferably, the swing arm assembly is provided with a proximity switch that can communicate with the electrical control system, and the proximity switch is used to accurately detect the position of the swing arm assembly.

[0016] In summary, this utility model has the following advantages: (1) It adopts an electric lifting fork mechanism, which eliminates the traditional complex cylinder-driven fork structure, making the overall frame simpler and occupying less space; (2) Electrical control is relatively easy, reducing the difficulty of installation and debugging, and further saving installation and maintenance costs; (3) The electric fork lifting design is ingenious, making it easier for on-site electrical personnel to install and debug. The fork lifting and retraction actions are achieved by the motor rotating the rocker arm, making the operation convenient and quick; (4) The equipment has a high degree of automation and can achieve unmanned operation. The stacking and unpacking process of the material frame is automatically cyclical, which greatly improves production efficiency.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] like Figure 1-4 As shown, the electric stacking and unstacking equipment proposed in this embodiment includes a main frame 1, with a vertical guide rail 11 provided on the inner side of the main frame 1, and also includes:

[0026] The material frame fork assembly includes two fork mechanisms 2 located on the inner sides of the main frame 1 respectively. The fork mechanism 2 can slide into the vertical guide rail 11 on the corresponding side. The fork mechanism 2 includes a hook 21 that can extend or retract. The hook 21 extends to pick up the side of the material frame.

[0027] The lifting drive assembly 4 is used to drive the forklift mechanism 2 to move up and down along the guide rail;

[0028] The swing arm drive assembly 5 is connected to the hook 21 via a crank rocker mechanism and is used to drive the hook 21 to extend or retract.

[0029] The electrical control system 3 is communicatively connected to the lifting drive assembly 4 and the swing arm drive assembly 5.

[0030] Thus, by adopting the electric lifting fork mechanism 2, the traditional complex cylinder-driven fork structure is eliminated, resulting in a simpler overall frame and smaller footprint. Electrical control is relatively easy, reducing installation and debugging difficulties and further saving installation and maintenance costs. The electric fork lifting design is ingenious, making installation and debugging simpler for on-site electrical personnel. The fork lifting and retraction actions are achieved by the motor rotating the rocker arm, making operation convenient and quick. The equipment has a high degree of automation, enabling unmanned operation. The stacking and unstacking process of the material frame is automatically cyclical, greatly improving production efficiency.

[0031] Furthermore, the lifting drive assembly 4 includes a lifting motor 41 and a drive shaft 42. The lifting motor 41 drives the drive shaft 42 to rotate. Both ends of the drive shaft 42 are fixed with gear and sprocket welded parts 43. The gear and sprocket welded parts 43 are designed as composite transmission components integrating gears and sprockets. One side of the gear meshes with the transmission gear, and the other side is connected to the reverse drive chain 44 through the sprocket. The first ends of two lifting chains 46 are connected and fixed on both sides of the reverse drive chain 44. The second ends of the lifting chains 46 are fixed to the forklift mechanism 2 through the connector 45. The two lifting chains 46 correspond to the forklift mechanisms 2 on both sides, forming a "left-right linkage" transmission structure.

[0032] Furthermore, the reverse drive chain 44 is wound in a ring around the sprocket of the gear sprocket welded part 43. When the drive shaft 42 rotates, the gear sprocket welded part 43 rotates synchronously, driving the sprocket of the gear sprocket welded part 43 to rotate. The upper chain of the reverse drive chain 44 moves towards the lifting motor 41, and the lower chain moves away from the lifting motor 41, forming a tension in opposite directions. The movement of the reverse drive chain 44 is transmitted to the lifting chains 46 on both sides. The lifting chains 46 on both sides move in opposite directions, thus the lifting chains 46 on both sides are stretched synchronously and in opposite directions, driving the forklift mechanism 2 to lift vertically.

[0033] Preferably, the forklift mechanism 2 is fixed with a guide wheel 22, which is slidably connected within the vertical guide rail 11. This guide wheel 22 is used to limit the chain's movement trajectory, preventing chain deviation or jamming, and simultaneously ensuring the smoothness and accuracy of the lifting process by changing the chain's direction (such as steering or tensioning).

[0034] Thus, through the linkage design of the reverse drive chain 44 and the lifting chain 46, the lifting and lowering movements of the forklift mechanisms 2 on both sides of the equipment are completely synchronized, avoiding tilting or jamming of the material frame due to uneven force on both sides; the "reverse pull" characteristic of the reverse drive chain 44 makes the lifting chains 46 on both sides form a symmetrical force structure, so that the material frame is subjected to uniform force during the lifting process and has higher stability; compared with the complex linkage mechanism of traditional cylinder drive, the chain drive structure is more compact, occupies less space, and is easy to adapt to the stacking requirements of material frames of different heights by adjusting the chain length or the number of sprocket teeth; synchronous movement is directly achieved through mechanical transmission, without the need for complex air pressure control, resulting in high transmission accuracy and low maintenance costs.

[0035] In this embodiment, the swing arm drive assembly 5 includes a swing arm drive motor 51. The output shaft of the swing arm drive motor 51 is fixed to the crank in the crank-rocker mechanism. The crank is connected to one end of the rocker through a rotating joint. The other end of the rocker is hinged to the swing arm assembly 52. ​​The end of the swing arm assembly 52 is fixedly connected to the hook 21 for picking up and placing the material frame.

[0036] The crank-rocker mechanism utilizes the circular motion of the crank to convert it into the oscillation of the rocker, efficiently converting the rotational motion of the motor into the reciprocating oscillation (extension or retraction) of the hook 21. Through the rational design of the length of the crank and rocker and the position of the hinge point, this mechanism can precisely control the extension and retraction stroke and angle of the hook 21, ensuring that the hook 21 accurately picks up and places the material frame. Compared to traditional complex transmission structures, the crank-rocker mechanism features a simple structure, smooth transmission, and high motion precision, while reducing mechanical wear, lowering maintenance costs, and improving the reliability and service life of the equipment.

[0037] Meanwhile, the electric destacking and stacking frame device in this embodiment also includes sensors and limiting devices (not shown in the figure) that can be communicated with the electrical control system 3. The sensors and limiting devices are used to detect and control the position of each component.

[0038] Preferably, the swing arm assembly 52 is provided with a proximity switch (not shown in the figure) that can communicate with the electrical control system 3. The proximity switch is used to accurately detect the position of the swing arm assembly 52.

[0039] Hook 21 extension process:

[0040] When the conveyor line delivers the empty material frame to the stacking station, the sensor detects the material frame's arrival signal, and the electrical control system 3 sends a command to the swing arm drive assembly 5. The swing arm drive assembly 5 starts, and the output shaft of the swing arm drive motor 51 drives the crank to rotate clockwise around the fixed shaft. As the crank rotates, it drives the rocker arm through the rotary joint. Due to the hinged relationship between the crank and the rocker arm, the rocker arm swings away from the main frame 1 from its initial position under the drive of the crank. The swing of the rocker arm then drives the swing arm assembly 52, which is hinged to it, to swing synchronously, so that the hook 21 at the end of the swing arm assembly 52 gradually extends towards the material frame. When the hook 21 reaches the preset fork position, the proximity switch on the swing arm assembly 52 detects the signal and feeds it back to the electrical control system 3. The swing arm drive motor 51 stops rotating, and the hook 21 remains stably in the extended state, completing the preparation for fork-taking the material frame.

[0041] At the same time, the lifting motor 41 drives the sprocket and chain on the transmission shaft 42 to move, causing the forked material frame to move up and down. Specifically, the lifting motor 41 drives the transmission shaft 42 to rotate, and the gear and sprocket welded parts 43 on the transmission shaft 42 rotate accordingly, driving the reverse drive chain 44 to move. The upper chain of the reverse drive chain 44 moves towards the lifting motor 41, while the lower chain moves to the opposite side, thereby pulling up the lifting chains 46 at both ends, lifting the empty material frame to the set height and then stopping.

[0042] Hook 21 retraction process:

[0043] After the lifting and placement of the material frame is completed, the electrical control system 3 sends another command to the swing arm drive assembly 5. The swing arm drive motor 51 reverses, and the output shaft drives the crank to make a counterclockwise circular motion. At this time, the rotation direction of the crank changes, and the rocker arm is pulled towards the main frame 1 through the rotary joint. The return swing of the rocker arm drives the swing arm assembly 52 to swing in the opposite direction in sync, so that the hook 21 gradually retracts from the fork position to the initial position. When the hook 21 is completely retracted to the set placement position, the proximity switch detects the signal and feeds back, the swing arm drive motor 51 stops rotating, and the hook 21 remains in the retracted state, waiting for the next work cycle.

[0044] Once the conveyor below transports the material frame to the appropriate position, the forklift mechanism 2 descends, retracts the hook 21, and then extends to the next layer, extending the hook 21. The lifting motor 41 then rotates, lifting the frame again. This cycle repeats to achieve the stacking and unstacking of the material frame. The entire process requires no manual operation, improving production efficiency, facilitating later maintenance and on-site installation, and effectively reducing equipment costs.
