Description

Technical Field

[0001] This invention relates to the field of material destacking technology, and in particular to an electrochemical marking device for material destacking. Background Technology

[0002] In the fields of automated production and logistics warehousing, depalletizing and labeling of materials are key processes connecting upstream and downstream processes. A common work scenario is that materials are stacked on pallets in multiple layers and rows. The materials need to be removed from the pallets one by one or layer by layer by a depalletizing device and transferred to the labeling station for identification. Finally, they are sent out in sequence for subsequent packaging or assembly.

[0003] Currently, there are several mature solutions for depalletizing materials, such as vacuum suction cups, pneumatic grippers, or multi-axis robotic arms. These devices can typically grasp, lift, and transfer materials. Meanwhile, in marking technology, electrochemical marking is widely used for marking metallic or conductive materials due to its advantages such as clear marking, corrosion resistance, and no damage to the workpiece surface.

[0004] However, existing depalletizing and marking operations often suffer from the following problems: process separation and low integration; depalletizing and marking equipment are usually set up independently, requiring materials to be transferred between different devices via additional conveyor lines or manual handling, resulting in large equipment footprint, long process flow time, and poor automation continuity; insufficient depalletizing adaptability; for multi-layered pallets, materials of different heights, or closely packed materials, the picking mechanism of existing depalletizing devices cannot flexibly adjust the picking position, easily leading to unstable gripping, material damage, or inability to adapt to changes in the overall height of the pallet; and poor conveying connection; when the depalletizing mechanism raises and lowers as a whole to adapt to different heights, the subsequent conveying mechanism, especially the transition conveying between different heights, often cannot adjust synchronously, easily causing materials to jam or fall between high and low conveyor belts, affecting the continuity of operations.

[0005] Therefore, it is necessary to develop an automated device that highly integrates depalletizing, conveying and electrochemical marking functions, and can flexibly adapt to multi-layer material handling, smooth transition conveying and adjustable marking position, so as to improve overall operation efficiency and reliability. Summary of the Invention

[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution: an electrochemical marking device for destacking materials, comprising a feeding mechanism for feeding a pallet and materials stacked on the pallet, a taking mechanism for destacking and marking the materials on the pallet next to the feeding mechanism, and a sending mechanism for sending the marked materials out next to the taking mechanism, the sending mechanism comprising a lower frame.

[0007] Furthermore, the feeding mechanism includes a feeding frame, on which multiple feeding rollers are rotatably mounted. A synchronous belt is wound between two adjacent feeding rollers. A feeding motor is fixedly mounted on the feeding frame, and the motor shaft of the feeding motor is fixedly mounted to the innermost feeding roller.

[0008] Furthermore, the feeding mechanism also includes a side-push electric cylinder fixedly installed on the feeding frame, a side push plate fixedly installed on the output end of the side-push electric cylinder, side limit rods fixedly installed on both sides of the feeding frame, a blocking electric cylinder fixedly installed at the innermost end of the feeding frame, and a blocking block fixedly installed on the output end of the blocking electric cylinder.

[0009] In use, the pallet with the stacked material is placed on the feed rollers. The side limit rods limit the two sides of the pallet. The feed motor drives the innermost feed roller to rotate, and the synchronous belt drives all the feed rollers to rotate synchronously. The feed rollers transport the pallet to the innermost end. The blocking electric cylinder is in the extended state under normal conditions. When the pallet contacts the blocking block, the blocking block blocks the pallet. Then the side push electric cylinder extends and drives the side push plate to move. The side push plate pushes the pallet to the side of the lower frame.

[0010] Furthermore, the retrieval mechanism includes a lifting guide column slidably mounted on the lower frame, a lifting plate fixedly mounted on the lifting guide column, an upper support frame fixedly mounted on the lifting plate, front and rear motors fixedly mounted on the upper support frame, front and rear lead screws rotatably mounted on the upper support frame, the front and rear lead screws being fixedly mounted to the motor shafts of the front and rear motors, front and rear slide rails fixedly mounted on the upper support frame, and front and rear moving frames slidably mounted on the front and rear slide rails, with the front and rear moving frames and the front and rear lead screws forming a threaded transmission.

[0011] Furthermore, the taking mechanism also includes left and right slide rails fixedly installed on the front and rear moving frames, left and right lead screws rotatably installed on the front and rear moving frames, left and right sliders slidably installed on the left and right slide rails, the left and right sliders and the left and right lead screws forming a threaded transmission, worm gears fixedly installed on the left and right lead screws, left and right motors fixedly installed on the front and rear moving frames, and worms fixedly installed on the motor shafts of the left and right motors, the worms meshing with the worm gears.

[0012] Furthermore, the retrieval mechanism also includes lifting electric cylinders fixedly installed on the left and right sliders, lifting guide columns slidably installed on the left and right sliders, lifting rods fixedly installed below the lifting guide columns, four clamping electric cylinders fixedly installed on the lifting rods, fixing rings fixedly installed on the clamping electric cylinders, three clamping rods rotatably installed on the fixing rings, lifting blocks fixedly installed on the output ends of the clamping electric cylinders, and inner rotating rods rotatably installed on the lifting blocks, with the inner rotating rods rotatably installed with the clamping rods.

[0013] The front and rear motors drive the front and rear lead screws to rotate, and the front and rear lead screws drive the front and rear moving frames to slide along the front and rear slide rails. The left and right motors drive the worm gear to rotate, and the worm gear drives the worm wheel and the left and right lead screws to rotate. The left and right lead screws drive the left and right sliders to slide along the left and right slide rails. The lifting electric cylinder retracts, causing the lifting rod and lifting guide column to rise and fall along the left and right sliders.

[0014] After the pallet moves to the side of the lower frame, the lifting rod moves to above the four materials at the front. Then, the lifting cylinder drives the lifting rod to descend, which in turn drives the four clamping cylinders to descend, allowing the clamping rods to enter the four materials at the top. The clamping cylinders then extend, causing the lifting block to extend, and the inner rotating rod drives the clamping rods to open outward, clamping the materials. Then, the lifting cylinder drives the lifting rod to rise, using the clamping rods to separate the top materials from the lower materials. Then, the front and rear moving frames slide along the front and rear slide rails to above the upper conveyor belt. Then, the lifting cylinder drives the lifting rod to descend, placing the materials on the upper conveyor belt. Then, the clamping cylinders retract, causing the clamping rods to close and disengage from the materials. Then, the lifting rod moves again to above the next batch of materials to be picked up, and so on, to pick up multiple layers and rows of materials on the pallet.

[0015] Furthermore, the delivery mechanism includes an upper conveyor belt mounted on a lifting plate, an upper motor for driving the upper conveyor belt to rotate fixedly mounted on the lifting plate, a delivery frame mounted next to the lower frame, a lower conveyor belt mounted on the delivery frame, and a lower motor for driving the lower conveyor belt to rotate fixedly mounted on the delivery frame.

[0016] Furthermore, the feeding mechanism also includes a limiting rail fixedly installed on the feeding frame, a guide slider slidably installed inside the limiting rail, a lower transmission roller rotatably installed on the guide slider, an inclined conveyor frame rotatably installed on the lifting plate, an upper transmission roller rotatably installed on the inclined conveyor frame, an inclined conveyor belt wrapped around the upper and lower transmission rollers, and an inclined motor for driving the upper transmission roller to rotate is provided on the lifting plate.

[0017] Furthermore, the feeding mechanism also includes a stand fixedly installed on the lifting plate, an upward adjustment motor fixedly installed on the top of the stand, an upward adjustment screw rotatably installed inside the lifting seat, the upward adjustment screw being fixedly installed with the motor shaft of the upward adjustment motor, a lifting seat slidably installed inside the stand, the lifting seat and the upward adjustment screw forming a threaded transmission, front and rear sliders slidably installed inside the lifting seat, an electrochemical marking machine fixedly installed on the front and rear sliders, a marking screw fixedly installed on the lifting seat, a marking motor rotatably installed inside the lifting seat, the marking motor being fixedly installed with the motor shaft of the marking screw, and the front and rear sliders and the marking motor forming a threaded transmission.

[0018] Furthermore, the delivery mechanism also includes a lifting motor fixedly installed on the lifting plate, and a lifting screw is fixedly installed on the motor shaft of the lifting motor, with the lifting screw forming a threaded transmission with the lower frame.

[0019] Initially, the electrochemical marking machine is located next to the upper conveyor belt, facilitating the material placement onto it by the pick-up mechanism. The upper motor drives the upper conveyor belt, the inclined motor drives the inclined conveyor belt, and the lower motor drives the lower conveyor belt. Once the material is placed on the upper conveyor belt, the marking screw drives the marking motor to rotate. The marking motor then drives the front and rear sliders and the electrochemical marking machine to slide forward along the lifting seat. Simultaneously, the rotation of the upper adjusting motor drives the upper adjusting screw to rotate, which in turn raises and lowers the lifting seat along the frame, thereby adjusting the height of the electrochemical marking machine. When the upper conveyor belt transports the material to the area below the electrochemical marking machine, the machine performs electrochemical marking on the material, thus marking all the material passing below it. The material is then conveyed onto the inclined conveyor belt, and subsequently onto the lower conveyor belt, from where it is discharged.

[0020] After each layer of material is removed, the lifting motor drives the lifting screw to rotate. Through the threaded transmission between the lifting screw and the lower frame, the lifting plate and lifting guide column descend along the lower frame, bringing the lifting rod closer to the next layer of material. This facilitates the removal of materials from different layers. When the lifting guide column and lifting plate descend along the lower frame, the upper end of the inclined conveyor frame rotates, and the lower end of the inclined conveyor frame drives the guide slider to slide within the limit rail. At this time, the inclined conveyor belt can still transport the material sent from the upper conveyor belt to the lower conveyor belt.

[0021] The beneficial effects of this invention compared with the prior art are: (1) This invention integrates the material destacking, transfer, marking and delivery processes into a continuous automated operation line by rationally arranging the feeding mechanism, the picking mechanism, the delivery mechanism and the electrochemical marking machine. The feeding mechanism automatically positions the pallet to the picking station. The picking mechanism, through the three-dimensional motion of front and back, left and right and lifting, cooperates with the clamping components to transfer the material layer by layer to the upper conveyor belt. Then, the electrochemical marking machine automatically marks the material and sends it out by the inclined conveyor belt and the lower conveyor belt. The whole process does not require manual intervention, which reduces the equipment footprint and material transfer time, and improves the production cycle and automation level; (2) In the picking mechanism set by this invention, the lifting motor drives the lifting screw to form a threaded transmission with the lower frame, which can drive the lifting plate and the entire picking component to rise and fall along the lifting guide column as a whole, so that the material is automatically lowered to the next layer after each layer is picked up. At the same time, the front and back... The moving frame, left and right sliders, and four independently controlled clamping electric cylinders and three-bar clamping rods can accurately grasp multi-layer, multi-row, and tightly arranged materials. The clamping rods achieve radial tension clamping through the inner rotating rod and the lifting block, which not only ensures the gripping firmness but also avoids damage to the materials. It is especially suitable for destacking scenarios where the stacks are neat but the layer height varies. (3) When the lifting plate of this invention is lowered as a whole to adapt to different layer heights, the upper end of the inclined conveyor frame set on the lifting plate is lowered accordingly. The lower end of the inclined conveyor frame slides in the limit rail through the guide slider, so that the inclined conveyor belt is always maintained in the transition connection state between the upper conveyor belt and the lower conveyor belt. This ensures that no matter what height the lifting plate is at, the materials sent from the liftable upper conveyor belt can be smoothly transferred to the fixed lower conveyor belt. This effectively solves the problem of conveying interruption, material accumulation or falling caused by height changes in traditional devices and improves the reliability of conveying.

Detailed Implementation

[0034] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0035] Example: Reference Figures 1-11An electrochemical marking device for destacking materials includes a feeding mechanism for feeding a pallet 5 and materials 4 stacked on the pallet 5 into the pallet 5, a taking mechanism for destacking and marking the materials 4 on the pallet 5 next to the feeding mechanism, and a sending mechanism for sending out the marked materials 4 next to the taking mechanism. The sending mechanism includes a lower frame 301.

[0036] like Figure 2 , Figure 3 As shown, the feeding mechanism includes a feeding frame 101, on which a plurality of feeding rollers 103 are rotatably mounted. A synchronous belt 108 is wound between two adjacent feeding rollers 103. A feeding motor 102 is fixedly mounted on the feeding frame 101, and the motor shaft of the feeding motor 102 is fixedly mounted to the innermost feeding roller 103.

[0037] like Figure 2 , Figure 3 As shown, the feeding mechanism also includes a side pusher cylinder 105 fixedly installed on the feeding frame 101. A side pusher plate 104 is fixedly installed on the output end of the side pusher cylinder 105. Side limit rods 109 are fixedly installed on both sides of the feeding frame 101. A blocking cylinder 106 is fixedly installed at the innermost end of the feeding frame 101. A blocking block 107 is fixedly installed on the output end of the blocking cylinder 106.

[0038] In use, the pallet 5 with the material 4 stacked is placed on the feeding roller 103. The side limit rod 109 limits the two sides of the pallet 5. The feeding motor 102 drives the innermost feeding roller 103 to rotate. The synchronous belt 108 drives all the feeding rollers 103 to rotate synchronously. The feeding roller 103 transports the pallet 5 to the innermost end. The blocking electric cylinder 106 is in the extended state under normal conditions. When the pallet 5 comes into contact with the blocking block 107, the blocking block 107 blocks the pallet 5. Then the side push electric cylinder 105 extends and drives the side push plate 104 to move. The side push plate 104 pushes the pallet 5 to the side of the lower frame 301.

[0039] like Figures 4-8 As shown, the retrieval mechanism includes a lifting guide column 214 slidably mounted on the lower frame 301, a lifting plate 201 fixedly mounted on the lifting guide column 214, an upper support frame 202 fixedly mounted on the lifting plate 201, a front and rear motor 203 fixedly mounted on the upper support frame 202, a front and rear lead screw 205 rotatably mounted on the upper support frame 202, the front and rear lead screw 205 being fixedly mounted to the motor shaft of the front and rear motor 203, a front and rear slide rail 204 fixedly mounted on the upper support frame 202, a front and rear moving frame 206 slidably mounted on the front and rear slide rail 204, and the front and rear moving frame 206 forming a threaded transmission with the front and rear lead screw 205.

[0040] like Figures 4-8As shown, the retrieval mechanism also includes left and right slide rails 207 fixedly installed on the front and rear moving frame 206. Left and right lead screws 209 are rotatably installed on the front and rear moving frame 206. Left and right sliders 208 are slidably installed on the left and right slide rails 207. The left and right sliders 208 and the left and right lead screws 209 form a threaded transmission. Worm gears 212 are fixedly installed on the left and right lead screws 209. Left and right motors 210 are fixedly installed on the front and rear moving frame 206. Worms 211 are fixedly installed on the motor shafts of the left and right motors 210. Worms 211 mesh with worm gears 212.

[0041] like Figures 4-8 As shown, the retrieval mechanism also includes a lifting electric cylinder 215 fixedly installed on the left and right sliders 208. A lifting guide column 214 is slidably installed on the left and right sliders 208. A lifting rod 213 is fixedly installed below the lifting guide column 214. Four clamping electric cylinders 216 are fixedly installed on the lifting rod 213. A fixing ring 217 is fixedly installed on the clamping electric cylinder 216. Three clamping rods 220 are rotatably installed on the fixing ring 217. A lifting block 218 is fixedly installed on the output end of the clamping electric cylinder 216. An inner rotating rod 219 is rotatably installed on the lifting block 218. The inner rotating rod 219 is rotatably installed with the clamping rods 220.

[0042] The front and rear motors 203 drive the front and rear lead screws 205 to rotate, and the front and rear lead screws 205 drive the front and rear moving frames 206 to slide along the front and rear slide rails 204. The left and right motors 210 drive the worm gear 211 to rotate, and the worm gear 211 drives the worm wheel 212 and the left and right lead screws 209 to rotate. The left and right lead screws 209 drive the left and right sliders 208 to slide along the left and right slide rails 207. The lifting electric cylinder 215 retracts, driving the lifting rod 213 and the lifting guide column 214 to rise and fall along the left and right sliders 208.

[0043] When the pallet 5 moves to the side of the lower frame 301, the lifting rod 213 moves to above the four materials 4 at the front. Then, the lifting cylinder 215 drives the lifting rod 213 to descend. The descent of the lifting rod 213 drives the four clamping cylinders 216 to descend, so that the clamping rods 220 enter the four uppermost materials 4. Then, the clamping cylinders 216 extend, causing the lifting block 218 to extend. Through the inner rotating rod 219, the clamping rods 220 open outward, clamping the materials 4. Then, the lifting cylinder 215 drives the lifting rod 213 to rise. The clamping rod 220 causes the top material 4 to detach from the bottom material 4. Then, the front and rear moving frame 206 slides along the front and rear slide rails 204 to the top of the upper conveyor belt 307. Then, the lifting cylinder 215 drives the lifting rod 213 to descend, placing the material 4 on the upper conveyor belt 307. Then, the clamping cylinder 216 retracts, causing the clamping rod 220 to close and detach from the material 4. Then, the lifting rod 213 moves again to the top of the next batch of material 4 to be picked up. This process is repeated to pick up multiple layers and rows of material 4 on the pallet 5.

[0044] like Figures 9-11 As shown, the delivery mechanism includes an upper conveyor belt 307 mounted on a lifting plate 201, an upper motor 306 fixedly mounted on the lifting plate 201 for driving the upper conveyor belt 307 to rotate, a delivery frame 302 mounted next to the lower frame 301, a lower conveyor belt 311 mounted on the delivery frame 302, and a lower motor 312 fixedly mounted on the delivery frame 302 for driving the lower conveyor belt 311 to rotate.

[0045] like Figures 9-11 As shown, the feeding mechanism also includes a limiting rail 303 fixedly installed on the feeding frame 302. A guide slider 313 is slidably installed inside the limiting rail 303. A lower transmission roller 315 is rotatably installed on the guide slider 313. An inclined conveyor frame 308 is rotatably installed on the lifting plate 201. An upper transmission roller 316 is rotatably installed on the inclined conveyor frame 308. An inclined conveyor belt 310 is wound around the upper transmission roller 316 and the lower transmission roller 315. An inclined motor 309 for driving the upper transmission roller 316 to rotate is provided on the lifting plate 201.

[0046] like Figures 9-11 As shown, the feeding mechanism also includes a stand 317 fixedly installed on the lifting plate 201. An upward adjustment motor 318 is fixedly installed on the top of the stand 317. An upward adjustment screw 319 is rotatably installed inside the lifting seat 320. The upward adjustment screw 319 is fixedly installed with the motor shaft of the upward adjustment motor 318. The lifting seat 320 is slidably installed inside the stand 317. The lifting seat 320 and the upward adjustment screw 319 form a threaded transmission. A front and rear slider 321 is slidably installed inside the lifting seat 320. An electrochemical marking machine 314 is fixedly installed on the front and rear sliders 321. A marking screw 323 is fixedly installed on the lifting seat 320. A marking motor 322 is rotatably installed inside the lifting seat 322. The marking motor 322 and the motor shaft of the marking screw 323 are fixedly installed. The front and rear sliders 321 and the marking motor 322 form a threaded transmission.

[0047] like Figures 9-11 As shown, the delivery mechanism also includes a lifting motor 304 fixedly installed on the lifting plate 201. A lifting screw 305 is fixedly installed on the motor shaft of the lifting motor 304, and the lifting screw 305 forms a threaded transmission with the lower frame 301.

[0048] Initially, the electrochemical marking machine 314 is positioned next to the upper conveyor belt 307, facilitating the placement of material 4 onto the upper conveyor belt 307 by the picking mechanism. The upper motor 306 drives the upper conveyor belt 307 to move, the inclined motor 309 drives the inclined conveyor belt 310 to rotate, and the lower motor 312 drives the lower conveyor belt 311 to rotate. After material 4 is placed onto the upper conveyor belt 307, the marking screw 323 drives the marking motor 322 to rotate. The marking motor 322 drives the front and rear sliders 321 and the electrochemical marking machine 314 to slide forward along the lifting seat 320. Simultaneously, the upper motor 31... Rotating the screw 319 can drive the lifting seat 320 to rise and fall along the frame 317, thereby adjusting the height of the electrochemical marking machine 314. When the upper conveyor belt 307 transports the material 4 to the area below the electrochemical marking machine 314, the electrochemical marking machine 314 performs electrochemical marking on the material 4, thus marking all the material 4 passing below it. Then, the material 4 is transported to the inclined conveyor belt 310, and then the material 4 reaches the lower conveyor belt 311, and is sent out by the lower conveyor belt 311.

[0049] After each material 4 on the same layer is taken, the lifting motor 304 drives the lifting screw 305 to rotate. Through the threaded transmission between the lifting screw 305 and the lower frame 301, the lifting plate 201 and the lifting guide column 214 descend along the lower frame 301, so that the lifting rod 213 is close to the next layer of material 4, which facilitates the taking of material 4 from different layers. When the lifting guide column 214 and the lifting plate 201 descend along the lower frame 301, the upper end of the inclined conveyor frame 308 will rotate. The lower end of the inclined conveyor frame 308 drives the guide slider 313 to slide within the limit rail 303. At this time, the inclined conveyor belt 310 can still transport the material 4 sent out by the upper conveyor belt 307 to the lower conveyor belt 311.

[0050] The working principle of the material destacking electrochemical marking device disclosed in this invention is as follows: When in use, the pallet 5 with the material 4 stacked is placed on the feeding roller 103. The side limiting rod 109 limits the two sides of the pallet 5. The feeding motor 102 drives the innermost feeding roller 103 to rotate. The synchronous belt 108 drives all the feeding rollers 103 to rotate synchronously. The feeding roller 103 transports the pallet 5 to the innermost end. The blocking electric cylinder 106 is in the extended state under normal conditions. When the pallet 5 contacts the blocking block 107, the blocking block 107 blocks the pallet 5. Then the side pushing electric cylinder 105 extends and drives the side pushing plate 104 to move. The side pushing plate 104 pushes the pallet 5 to the side of the lower frame 301.

[0051] The front and rear motors 203 drive the front and rear lead screws 205 to rotate, and the front and rear lead screws 205 drive the front and rear moving frames 206 to slide along the front and rear slide rails 204. The left and right motors 210 drive the worm gear 211 to rotate, and the worm gear 211 drives the worm wheel 212 and the left and right lead screws 209 to rotate. The left and right lead screws 209 drive the left and right sliders 208 to slide along the left and right slide rails 207. The lifting electric cylinder 215 retracts, driving the lifting rod 213 and the lifting guide column 214 to rise and fall along the left and right sliders 208. When the pallet 5 moves to the side of the lower frame 301, the lifting rod 213 moves to above the four materials 4 at the front. Then, the lifting cylinder 215 drives the lifting rod 213 to descend. The descent of the lifting rod 213 drives the four clamping cylinders 216 to descend, so that the clamping rods 220 enter the four uppermost materials 4. Then, the clamping cylinders 216 extend, causing the lifting block 218 to extend. Through the inner rotating rod 219, the clamping rods 220 open outward, clamping the materials 4. Then, the lifting cylinder 215 drives the lifting rod 213 to rise. The clamping rod 220 causes the top material 4 to detach from the bottom material 4. Then, the front and rear moving frame 206 slides along the front and rear slide rails 204 to the top of the upper conveyor belt 307. Then, the lifting cylinder 215 drives the lifting rod 213 to descend, placing the material 4 on the upper conveyor belt 307. Then, the clamping cylinder 216 retracts, causing the clamping rod 220 to close and detach from the material 4. Then, the lifting rod 213 moves again to the top of the next batch of material 4 to be picked up. This process is repeated to pick up multiple layers and rows of material 4 on the pallet 5.

[0052] Initially, the electrochemical marking machine 314 is positioned next to the upper conveyor belt 307, facilitating the placement of material 4 onto the upper conveyor belt 307 by the picking mechanism. The upper motor 306 drives the upper conveyor belt 307 to move, the inclined motor 309 drives the inclined conveyor belt 310 to rotate, and the lower motor 312 drives the lower conveyor belt 311 to rotate. After material 4 is placed onto the upper conveyor belt 307, the marking screw 323 drives the marking motor 322 to rotate. The marking motor 322 drives the front and rear sliders 321 and the electrochemical marking machine 314 to slide forward along the lifting seat 320. Simultaneously, the upper motor 31... Rotating the screw 319 can drive the lifting seat 320 to rise and fall along the frame 317, thereby adjusting the height of the electrochemical marking machine 314. When the upper conveyor belt 307 transports the material 4 to the area below the electrochemical marking machine 314, the electrochemical marking machine 314 performs electrochemical marking on the material 4, thus marking all the material 4 passing below it. Then, the material 4 is transported to the inclined conveyor belt 310, and then the material 4 reaches the lower conveyor belt 311, and is sent out by the lower conveyor belt 311.

[0053] After each material 4 on the same layer is taken, the lifting motor 304 drives the lifting screw 305 to rotate. Through the threaded transmission between the lifting screw 305 and the lower frame 301, the lifting plate 201 and the lifting guide column 214 descend along the lower frame 301, so that the lifting rod 213 is close to the next layer of material 4, which facilitates the taking of material 4 from different layers. When the lifting guide column 214 and the lifting plate 201 descend along the lower frame 301, the upper end of the inclined conveyor frame 308 will rotate. The lower end of the inclined conveyor frame 308 drives the guide slider 313 to slide within the limit rail 303. At this time, the inclined conveyor belt 310 can still transport the material 4 sent out by the upper conveyor belt 307 to the lower conveyor belt 311.

Any equivalent substitutions or modifications 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.
