Description

Technical Field

[0001] This invention relates to the field of bar stacking technology, and in particular to an automatic stacking and bundling device for aluminum alloy bars. Background Technology

[0002] Aluminum alloy bars, as an important industrial raw material, are widely used in metallurgy, aerospace, and automotive manufacturing. During their production, storage, and transportation, multiple bars typically need to be stacked in layers and secured with steel or plastic strapping to facilitate subsequent lifting, handling, and storage. Currently, the stacking and bundling of aluminum alloy bars still largely relies on manual labor or semi-mechanized equipment. Traditional methods often suffer from the following problems: the picking, transferring, aligning, and stacking of bars require significant manual intervention, resulting in high labor intensity, low production efficiency, and difficulty in meeting the cycle time and efficiency requirements of modern production lines. Production capacity requirements; during manual stacking, it is difficult to align the layers of bars, resulting in unstable stacks that are prone to scattering and collapse during handling. This can damage the surface quality of the bars and pose a threat to the safety of operators. Existing bundling equipment is often single-function and cumbersome, especially when fitting cable ties into large stacks, making operation difficult and ensuring that the ties are evenly and tightly bound at both ends of the stack, leading to insecure binding and loosening during transportation. Cylindrical bars, after stacking, especially when tilted or subjected to vibration, pose a risk of rolling off the sides of the stack. Current technology lacks an anti-roll mechanism that can be automatically triggered during stacking and adaptively adjusted according to the stack height, further increasing the instability and danger of the operation. To solve these problems, there is an urgent need in the field for a fully automated device that integrates automatic stacking, precise alignment, reliable anti-rolling, and efficient bundling to achieve efficient, safe, and stable aluminum alloy bar stacking and bundling operations.

A bottom sliding column is fixedly installed below the lifting plate, and a lifting plate is slidably installed on the bottom sliding column. Two docking columns are rotatably installed below the lifting plate.

[0006] Furthermore, a side sliding column is slidably installed below the lifting plate, and a side positioning plate and an inward slope block are fixedly installed at both ends of the side sliding column, respectively. A side sliding spring is provided between the side positioning plate and the lifting plate. A slope surface is provided on the lower surface of the inward slope block. Through grooves are provided on both sides of the lifting plate, and the edge of the through groove of the lifting plate contacts the slope surface of the lower surface of the inward slope block.

[0007] Furthermore, the binding mechanism includes a cable tie frame fixedly installed on the stacking frame, four insertion electric cylinders fixedly installed on the cable tie frame, a support wheel fixedly installed on the output end of the insertion electric cylinder, cable ties wrapped around the four support wheels, and the remaining cable ties wrapped around the outside of the cable tie frame.

[0008] Furthermore, a crossbeam is fixedly installed on the cable tie frame, a tensioning frame is fixedly installed on the crossbeam, a front and rear movable frame is slidably installed on the tensioning frame, a front and rear motor is fixedly installed on the tensioning frame, a front and rear lead screw is rotatably installed on the tensioning frame, the front and rear lead screw is fixedly installed with the motor shaft of the front and rear motor, the front and rear movable frame and the front and rear lead screw form a threaded transmission, an inner and outer motor is fixedly installed on the front and rear movable frame, an inner and outer lead screw is rotatably installed inside the front and rear movable frame, the inner and outer lead screw is fixedly installed with the motor shaft of the inner and outer motor, and an end block is slidably installed below the front and rear movable frame, the end block and the inner and outer lead screw form a threaded transmission.

[0009] Furthermore, a tensioning motor is fixedly installed on the end block, a drive wheel is fixedly installed on the motor shaft of the tensioning motor, a driven wheel is rotatably installed on the end block, and the end of the cable tie is located between the drive wheel and the driven wheel.

[0010] Furthermore, an inner retracting rod is fixedly installed on the anti-roll plate, a sliding rod is fixedly installed on the inner retracting rod, a sleeve is fixedly installed below the support plate, the sliding rod and the sleeve are slidably installed, an inner plug is fixedly installed on the sliding rod, the inner plug slides along the inner wall of the sleeve, the sleeve is connected to the oil pressure cylinder through an oil pipe, and the oil pressure cylinder, oil pipe, and the space between the sleeve and the inner plug are filled with oil.

[0011] The beneficial effects of this invention compared with the prior art are: (1) This invention achieves full automation of the entire process from pallet supply, bar picking, center alignment, layer stacking to final automatic bundling through the coordinated cooperation of stacking mechanism, bundling mechanism and anti-roll mechanism. Through the precise movement of moving frame, lifting plate and side bracket, material transfer and stacking are continuously completed, and bundling is carried out through automated bundling mechanism, which greatly reduces manual intervention, overcomes the problems of low efficiency and high labor intensity of traditional methods, and significantly improves overall production efficiency; (2) In the process of grabbing bars, the stacking mechanism set in this invention can automatically center and align the scattered bars when it descends to grab them, ensuring the neatness of each layer of bars and the entire stack, forming a stable and orderly stack, laying a solid foundation for subsequent safe bundling, transportation and storage. (3) The anti-roll mechanism of this invention uses the weight of the bar as a power source. When the bar is placed on the pallet and the lower guide post is pressed down, the anti-roll plate is driven to move inward through the hydraulic oil circuit, automatically clamping the two ends of the bar. No additional sensors or electric drive components are required. The structure is simple, the response is fast, and the reliability is high. It effectively prevents the bar from rolling and falling during and after stacking, greatly improving the safety of operation. (4) The binding mechanism of this invention realizes the automatic insertion and tightening of the cable tie through the cooperation of the electric cylinder, the support wheel and the tensioning component. The four support wheels pre-open the cable tie so that it can be smoothly inserted into the stack. Then, by shrinking the support wheels one by one and cooperating with the tensioning motor to rewind, the cable tie is smoothly pulled out from the support wheels and tightly bound to the stack.

Detailed Implementation

[0026] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] Example: Reference Figures 1-13 An automatic stacking and bundling device for aluminum alloy bars includes a stacking mechanism for stacking aluminum alloy bars. The stacking mechanism includes a stacking frame 101. The stacking mechanism is provided with two bundling mechanisms for bundling the stacked aluminum alloy bars and an anti-rolling mechanism for preventing the aluminum alloy bars from rolling out during the stacking process. The stacking mechanism includes a tray 104 fixedly installed on the stacking frame 101, on which multiple trays 106 are stacked.

[0028] like Figures 2-7 As shown, the stacking mechanism also includes a feeding platform 102 and a placement platform 105 fixedly installed on the stacking frame 101. Two horizontal guide rails 103 are fixedly installed on the stacking frame 101. A movable frame 107 is slidably installed on the horizontal guide rails 103. Multiple movable wheels 108 are rotatably installed on the movable frame 107. The movable wheels 108 roll along the horizontal guide rails 103. A motor for driving the movable wheels 108 is provided on the movable frame 107.

[0029] like Figures 2-7 As shown, a lifting plate 117 is slidably installed below the mobile frame 107. A winch 118 is provided on the mobile frame 107 to control the lifting of the lifting plate 117. Two side brackets 109 are rotatably installed below the lifting plate 117. A motor is provided on the lifting plate 117 to drive the side brackets 109 to rotate. A bottom sliding column 116 is fixedly installed below the lifting plate 117. A lifting plate 110 is slidably installed on the bottom sliding column 116. Two docking columns 111 are rotatably installed below the lifting plate 110.

[0030] like Figures 2-7 As shown, a side sliding column 113 is slidably installed below the lifting plate 117. A side positioning plate 115 and an inward slope block 112 are fixedly installed at both ends of the side sliding column 113. A side sliding spring 114 is provided between the side positioning plate 115 and the lifting plate 117. A slope is provided on the lower surface of the inward slope block 112. Through grooves are provided on both sides of the lifting plate 110. The edge of the through groove of the lifting plate 110 contacts the slope of the lower surface of the inward slope block 112.

[0031] First, the moving wheel 108 moves the moving frame 107 to above the tray 104. The winch 118 lowers the lifting plate 117, and the side bracket 109 rotates to pick up the tray 106. Then, the winch 118 raises the lifting plate 117, and the moving frame 107 moves above the placement platform 105. After the lifting plate 117 lowers, the side bracket 109 rotates outward to place the tray 106 on the placement platform 105.

[0032] The aluminum alloy bars to be stacked and bundled are placed flat on the feeding platform 102. The moving wheel 108 drives the moving frame 107 to slide along the horizontal guide rail 103, so that the lifting plate 117 reaches above the feeding platform 102. Then the winch 118 drives the lifting plate 117 to descend. When the docking column 111 on the lifting plate 110 contacts the upper surface of the aluminum alloy bar, the lifting plate 110 rises along the bottom sliding column 116. The edge of the through groove on the lifting plate 110 drives the inner slope block 112, the side sliding column 113 and the side positioning plate 115 to move inward through the slope of the lower surface of the inner slope block 112. The side sliding spring 114 is compressed, and the two side positioning plates 115 move inward at the same time, so that the two ends of all the aluminum alloy bars are aligned. Then the side bracket 109 rotates to grab all the aluminum alloy bars together with the moving support plate 106.

[0033] Subsequently, the winch 118 drives the lifting plate 117 to rise, and the moving frame 107 moves the aluminum alloy bars to the top of the placement platform 105. Then, all the bars are placed on the tray 106 located on the placement platform 105. Then, the tray 106 is placed on the aluminum alloy bars in sequence, and the bars are placed again. That is, a tray 106 is placed between each layer of aluminum alloy bars.

[0034] like Figures 8-10 As shown, the strapping mechanism includes a cable tie frame 201 fixedly installed on the stacking frame 101. Four insertion cylinders 202 are fixedly installed on the cable tie frame 201. Supporting wheels 203 are fixedly installed on the output end of the insertion cylinders 202. Cable ties 214 are wrapped around the four supporting wheels 203. The remaining cable ties 214 are wrapped around the outside of the cable tie frame 201.

[0035] like Figures 8-10 As shown, a crossbeam 204 is fixedly installed on the cable tie holder 201, a tensioning bracket 205 is fixedly installed on the crossbeam 204, a front and rear movable bracket 208 is slidably installed on the tensioning bracket 205, a front and rear motor 206 is fixedly installed on the tensioning bracket 205, a front and rear lead screw 207 is rotatably installed on the tensioning bracket 205, the front and rear lead screw 207 is fixedly installed with the motor shaft of the front and rear motor 206, the front and rear movable bracket 208 and the front and rear lead screw 207 form a threaded transmission, an inner and outer motor 209 is fixedly installed on the front and rear movable bracket 208, an inner and outer lead screw 210 is rotatably installed inside the front and rear movable bracket 208, the inner and outer lead screw 210 is fixedly installed with the motor shaft of the inner and outer motor 209, and an end block 215 is slidably installed below the front and rear movable bracket 208, the end block 215 and the inner and outer lead screw 210 form a threaded transmission.

[0036] like Figures 8-10 As shown, a tensioning motor 211 is fixedly installed on the end block 215, a drive wheel 212 is fixedly installed on the motor shaft of the tensioning motor 211, a driven wheel 213 is rotatably installed on the end block 215, and the end of the cable tie 214 is located between the drive wheel 212 and the driven wheel 213.

[0037] After the multi-layer aluminum alloy bars are stacked, four sleeve-type electric cylinders 202 extend, driving the support wheels 203 to extend. The four support wheels 203, along with the cable ties 214, disengage from the cable tie frame 201, causing the cable ties 214 to move to the outer side of the aluminum alloy bar end. The front and rear motors 206 drive the front and rear lead screws 207 to rotate, causing the front and rear moving frames 208 to move outward synchronously. At this time, the cable ties 214 are not yet wrapped around the outer side of the aluminum alloy bar. Then, one sleeve-type electric cylinder 202 retracts, causing one support wheel 203 to leave the inside of the cable tie 214. The tensioning motor 211 drives the drive wheel 212 to rotate, which in turn tightens the end of the cable tie 214. As the cable ties tighten, the support wheels 203 are pulled out of the cable ties 214 one by one, and the cable ties 214 are finally tied to both ends of the aluminum alloy rod. Then, the cable ties 214 are moved to the outermost end of the cable tie frame 201 by hand or mechanical means. The front and rear motors 206 rotate, driving the front and rear lead screws 207 to rotate, which can drive the front and rear moving frames 208 to slide along the tensioning frame 205. The inner and outer motors 209 rotate the inner and outer lead screws 210, driving the end blocks 215 to slide along the front and rear moving frames 208. The position of the end blocks 215 can be adjusted so that the end blocks 215 return to the initial position. The driving wheel 212 and the driven wheel 213 return to both sides of the end of the cable tie 214, ready for the next binding.

[0038] like Figures 11-13 As shown, each pallet 106 is provided with two anti-roll mechanisms. The anti-roll mechanism includes a lower guide post 302 slidably mounted on the pallet 106, a pressure bar 301 fixedly mounted on the lower guide post 302, a lower pressure post 304 fixedly mounted below the pressure bar 301, a pressure spring 303 between the pressure bar 301 and the pallet 106, an oil pressure cylinder 305 fixedly mounted on the pallet 106, the lower pressure post 304 sliding within the oil pressure cylinder 305, and two anti-roll plates 306 slidably mounted on the pallet 106.

[0039] like Figures 11-13 As shown, an inner retracting rod 310 is fixedly installed on the anti-roll plate 306, and a sliding rod 309 is fixedly installed on the inner retracting rod 310. A sleeve 308 is fixedly installed below the support plate 106. The sliding rod 309 and the sleeve 308 are slidably installed. An inner plug 311 is fixedly installed on the sliding rod 309. The inner plug 311 slides along the inner wall of the sleeve 308. The sleeve 308 is connected to the oil pressure cylinder 305 through the oil pipe 307. The oil pressure cylinder 305, the oil pipe 307, and the space between the sleeve 308 and the inner plug 311 are filled with oil.

[0040] When the aluminum alloy bar is placed on the support plate 106, it will press down the lower guide post 302, compress the lower spring 303, and the lower pressure post 304 will slide down along the oil cylinder 305, thereby squeezing the oil in the oil cylinder 305 downward. This causes the oil in the oil pipe 307 and the sleeve 308 to push the inner plug 311, the inner retracting rod 310 and the anti-roll plate 306 inward. The anti-roll plate 306 clamps the outermost end of the aluminum alloy bar to prevent it from rolling.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
