Description

Technical Field

[0001] This invention relates to the field of conveying technology, and in particular to a three-dimensional automatic feeding system. Background Technology

[0002] Before production, adjustments are typically made to the materials to be conveyed and their flow direction on the production line, based on the products to be manufactured, to ensure a continuous supply of materials during production. When the product type changes, the production line must be stopped, and the material conveying equipment and flow direction adjusted before production can resume. This process is time-consuming and hinders overall efficiency, especially for production lines where product types frequently change. Therefore, there is an urgent need for a system that provides more flexible and convenient material supply to production equipment. Utility Model Content

[0003] The purpose of this invention is to provide a three-dimensional automatic feeding system to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this invention is: A three-dimensional automatic feeding system includes: a three-dimensional storage machine, comprising a frame, storage and conveying devices, a transfer mechanism, a tilting mechanism, and a transfer bin. Multiple storage and conveying devices are spaced vertically within the frame and can reciprocate horizontally. The transfer mechanism is located within the frame beside the storage and conveying devices and includes vertically movable transfer and conveying devices that can convey materials towards or away from the storage and conveying devices. The tilting mechanism is located within the frame at the end of one of the storage and conveying devices and includes a tilting frame that can rotate horizontally on the frame. The machine is equipped with a vertically movable pressure plate. The transfer bin is located inside the frame below the tilting frame. A discharge port is provided on the bottom side of the transfer bin, and an opening / closing assembly is provided on the outside of the transfer bin to open or close the discharge port. A loading trolley is movable to move closer to or away from the conveying start end of the transfer conveying device. A loading conveying device is provided on the top side of the loading trolley, and the loading conveying device can convey materials in a direction close to the transfer conveying device. A unloading trolley is movable to move closer to or away from the discharge port. A hopper is provided on the top side of the unloading trolley, with an inlet on the top side of the hopper and an outlet on one side of the bottom of the hopper. A baffle plate is provided at the outlet of the hopper to open or close the outlet.

[0005] This technical solution has at least the following beneficial effects: During production, the loading trolley can move to different feeding devices, from which material boxes are sent to the loading conveyor. The loading trolley then moves to the beginning of the transfer conveyor, which then feeds the material boxes to the transfer conveyor of the transfer mechanism. At this point, the material boxes can be first placed into a storage conveyor for storage. The transfer conveyor moves the material boxes up and down to adjust them to different storage conveyors. Then, the transfer conveyor operates, sending the material boxes into the corresponding storage conveyor. This allows different materials to be placed into different storage conveyors for storage. When materials need to be output according to usage requirements, the storage conveyor directly loaded with the corresponding material can operate to output the material box. Alternatively, the storage conveyor can first send the material box back to the transfer conveyor, and then the transfer conveyor adjusts the material box to a designated output location. The material storage and conveying device feeds the material box onto the tilting frame. The pressure plate moves downward and presses against the top side of the material tray, pressing the tray firmly onto the tilting frame. Then, the tilting frame rotates along the horizontal axis, tilting the tray so that the material in the tray pours out into the transfer bin below. At this time, the opening and closing component in the transfer bin closes the transfer bin. After the material in the tray is completely poured out, the tilting frame reverses and resets, the pressure plate moves upward, releasing the pressure on the tray, and the unloading trolley moves to the bottom of the unloading port. The unloading port is opened by the opening and closing component, allowing the material to be poured into the lower bin. After unloading, the unloading trolley moves to the target equipment where material needs to be added, and the baffle plate at the discharge port is opened, allowing material to be fed into the target equipment from the discharge port. In this way, different materials can be temporarily stored in multiple storage and conveying devices arranged in a three-dimensional manner during production, and the corresponding materials can be sent out to the target equipment according to the needs of use, greatly improving the efficiency and flexibility of material conveying.

[0006] As a further improvement to the above technical solution, the unloading trolley is equipped with a lifting frame that can move vertically. The hopper is mounted on the lifting frame, and a first discharge chute that can extend or retract from below the discharge port is provided on the bottom side of the hopper. The lifting frame can move the hopper up and down. When the transfer silo needs to open its discharge port to unload material into the hopper, the lifting frame moves the hopper down, so that the hopper is located below the transfer silo. When it is necessary to add material to the target equipment, the lifting frame moves the hopper up, so that the hopper is above the target equipment, allowing for better material loading into the target equipment.

[0007] As a further improvement to the above technical solution, the lifting frame is equipped with a first motor and a first synchronous pulley. The first motor drives the first synchronous pulley. A second synchronous pulley is located outside the hopper. A first synchronous belt drives the first synchronous pulley and the second synchronous pulley. The first discharge chute is slidably connected to the outside of the hopper and connected to the first synchronous belt. When the first motor drives the first synchronous pulley to rotate, the first discharge chute can be extended or retracted from below the discharge port via the first synchronous belt. When discharge is required, the first motor operates, driving the first synchronous pulley to rotate and transmitting power to the first synchronous belt, causing the first synchronous belt to rotate on the first and second synchronous pulleys. Since the first discharge chute is connected to the first synchronous belt, as the first motor drives the first synchronous belt to rotate forward or reverse, the first discharge chute can be extended or retracted from below the discharge port.

[0008] As a further improvement to the above technical solution, a second discharge trough is slidably connected to the outside of the first discharge trough. A third synchronous pulley and a fourth synchronous pulley are spaced apart along the length of the first discharge trough. A second synchronous belt is connected between the third synchronous pulley and the fourth synchronous pulley. A fixed block is connected to the lifting frame. The fixed block is connected to one side of the second synchronous belt. The second discharge trough is connected to the other side of the second synchronous belt. When the first discharge trough slides relative to the lifting frame, the second discharge trough can be driven to extend or retract from the first discharge trough through the second synchronous belt. When the first discharge chute moves, the second synchronous belt on one side of the first discharge chute and the lifting frame form a fixed connection point, causing the second synchronous belt to rotate around the fixed block as a fulcrum. For example, when the first discharge chute extends out from below the discharge port, the second discharge chute can also extend out relative to the first discharge chute; when the first discharge chute is retracted back to the first discharge chute, the second discharge chute can also retract relative to the first discharge chute. In this way, the first discharge chute and the second discharge chute can form a two-stage extension and retraction on the bottom side of the hopper. When extending, it can extend to a longer length, and when retracting, it can be further retracted to the bottom side of the hopper.

[0009] As a further improvement to the above technical solution, a feeding conveyor is provided inside the tilting frame, located below the pressure plate. When the tray is fed into the tilting frame, the feeding conveyor supports the tray and assists in feeding it into place. After unloading the tray, the feeding conveyor returns it to the storage conveyor, thus achieving tray recycling. This improves the efficiency and convenience of feeding trays into and out of the tilting frame.

[0010] As a further improvement to the above technical solution, the transfer conveying device is a first roller conveyor. The first roller conveyor has multiple first conveying rollers arranged at intervals along a straight direction, with a first conveying gap formed between two adjacent first conveying rollers. A lifting drive is provided below the transfer conveying device, and a stop bar is driven and connected to the lifting drive. The lifting drive can drive the stop bar to move up and down within one of the first conveying gaps. At this time, the material is conveyed by the rotating first conveying rollers, while the stop bar moves up and down between two adjacent first conveying rollers, either protruding upwards from the first roller conveyor to block the material, or retracting downwards into the first roller conveyor to avoid the material.

[0011] As a further improvement to the above technical solution, a material-shifting mechanism is provided below the transfer conveying device. The material-shifting mechanism includes a material-shifting translation drive, a movable plate, and levers. The material-shifting translation drive is mounted on the frame and drives the movable plate. The frame is located beside the transfer conveying device and has a discharge port. The material-shifting translation drive can move the movable plate closer to or away from the discharge port. Multiple levers are arranged on the movable plate along the conveying direction of the transfer conveying device, and each lever passes upward through multiple first conveying gaps. After the material-filled box is emptied, the box can be sent out from the discharge port for recycling. Specifically, the empty box is transported back to the transfer conveying device. At this time, multiple levers are located on the side of the transfer conveying device away from the discharge port. The transfer conveying device moves down to the discharge port, and the material-shifting translation drive moves the multiple levers towards the discharge port, pushing the box out of the discharge port. This achieves the removal of the empty box.

[0012] As a further improvement to the above technical solution, a discharge conveying device is provided on the frame next to the discharge port, and a stacking mechanism is provided on the frame above the discharge conveying device. The stacking mechanism has a vertically movable transmission plate, and a lifting assembly is provided on the transmission plate. The lifting assembly has two lifting plates that can move closer or further apart. The material box output from the discharge port is placed on the discharge conveying device and conveyed in a straight line. When the material box moves past the stacking mechanism, the two lifting plates in the lifting assembly are in a state of being far apart. The transmission plate moves downward, causing the two lifting plates to move to a position on both sides of the material box. Then, the two lifting plates move closer together, clamping onto both sides of the material box, pulling the transmission plate upward to lift the material box. At this time, the next material box can continue to be conveyed on the discharge conveying device and moved to directly below the lifted material box. Then, the transmission plate moves downward to lift the material box. The two lifting plates within the component are positioned far apart, allowing the lifted boxes to be stacked on top of the boxes on the discharge conveyor, thus achieving vertical stacking of the boxes. This operation is repeated multiple times, allowing the boxes to be stacked directly after discharge. Once the boxes have been stacked to the required height, the lifting component no longer lifts the boxes on the discharge conveyor, which then directly sends the stacked boxes out. This allows for direct vertical stacking of the boxes during discharge, saving the steps of transferring and stacking the boxes after discharge, thereby improving overall production efficiency.

[0013] As a further improvement to the above technical solution, the lifting assembly includes connecting arms and lifting drive components. Two connecting arms are spaced apart on the transmission plate, and each connecting arm is equipped with a lifting drive component. Two lifting boxes are respectively mounted on the two lifting drive components, and the two lifting drive components can respectively drive the two lifting boxes to move closer or further apart. When the transmission plate moves the two connecting arms downwards, the two lifting drive components move the two lifting boxes to a state of distance from each other. After the two lifting boxes have moved to their lowered positions, the two lifting drive components move the two lifting boxes closer to the sides of the box, causing the two lifting boxes to be locked onto the sides of the box. At this point, the boxes can be lifted and stacked.

[0014] As a further improvement to the above technical solution, the two lifting drive components are each driven and connected to a connecting plate. The bottom sides of the two connecting plates are bent towards each other to form support edges. The two lifting box plates are respectively hinged to the two connecting plates. The two lifting box plates can rotate upward or downward to abut against the two support edges. When the two lifting box plates move directly downward relative to the material box while in a close-to-each-other state, the two lifting box plates rotate upward under the pressure of the two sides of the material box, avoiding the structure on both sides of the material box. When the two lifting box plates move downward to the sides of the material box located in the discharge conveying device, the two lifting box plates can rotate downward under the action of gravity to reset and abut against the two support edges. When the transmission plate moves upward, since the two support edges provide limiting support for the two lifting box plates, the lifting box plates can maintain the upward lifting state of the material box, thus improving the convenience of lifting and stacking the material box.

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of the present invention in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.

[0027] Reference Figure 1A three-dimensional automatic feeding system includes: a three-dimensional storage machine, comprising a frame 100, storage conveying devices 200, a transfer mechanism, a tilting mechanism, and a transfer bin 921. Multiple storage conveying devices 200 are spaced apart vertically within the frame 100 and can reciprocate horizontally. The transfer mechanism is located within the frame 100 beside the storage conveying devices 200 and includes a vertically movable transfer conveying device 310 that can convey materials towards or away from the storage conveying devices 200. The tilting mechanism is located within the frame 100 at one end of a storage conveying device 200 and includes a tilting frame 911 that can rotate horizontally along an axis on the frame 100. The tilting frame 911 has a vertically movable pressure plate 912. The transfer bin 921 is located within the frame 100 below the tilting frame 911. A discharge port is located on the bottom side of the transfer bin 921, and an opening / closing assembly is located on the outside of the transfer bin 921 to open or close the discharge port. A loading trolley is movable to approach or move away from the conveying start of the transfer conveyor 310. A loading conveyor is located on the top side of the loading trolley, and the loading conveyor can convey materials in a direction close to the transfer conveyor 310. In practical applications, the loading conveyor can be a belt conveyor or a roller conveyor, etc. A unloading trolley 500 is movable to approach or move away from the discharge port. A hopper 622 is located on the top side of the unloading trolley 500. An inlet 6221 is located on the top side of the hopper 622, and an outlet is located on one side of the bottom of the hopper 622. A baffle 623 is located at the outlet of the hopper 622, which can open or close the outlet.

[0028] In this three-dimensional automatic feeding system, during production, the loading trolley can move to different feeding devices, from which material boxes are fed to the loading conveyor. The loading trolley then moves to the beginning of the transfer conveyor 310, where it operates to deliver the material boxes to the transfer conveyor 310. At this point, the material boxes can be placed in the storage conveyor 200 for storage. The transfer conveyor 310 then moves the material boxes up and down to adjust them to correspond to different storage conveyors 200. Finally, the transfer conveyor... 310 operates by feeding the material box into the corresponding storage and conveying device 200. Different materials can be stored in different storage and conveying devices 200. When materials need to be output as required, the storage and conveying device 200 containing the corresponding material can operate directly to output the material box. Alternatively, the storage and conveying device 200 can first send the material box containing the material back to the transfer conveying device 310, and then the transfer conveying device 310 adjusts the material box to a corresponding storage and conveying device specifically designed for outputting materials. The material box is fed onto the tilting frame 911 by the storage and conveying device 200. The pressure plate 912 moves downward and presses against the top side of the material tray, pressing the material tray firmly onto the tilting frame 911. Then, the tilting frame 911 rotates along the horizontal axis, tilting the material tray so that the material in the tray pours out into the transfer chamber 921 located below. At this time, the opening and closing component in the transfer chamber 921 closes the transfer chamber 921. After the material in the tray is completely poured out, the tilting frame 911 reverses and resets, and the pressure plate 912 moves upward to release the pressure on the material tray, and the unloading trolley... The material trolley 500 moves to the bottom of the discharge port and opens the discharge port through the opening and closing component to pour the material into the hopper 622 located below. After the material is poured, the material trolley 500 moves to the target equipment where the material needs to be added and opens the baffle 623 located at the discharge port, so that the material can be put into the target equipment from the discharge port. In this way, during production, different materials can be temporarily stored in multiple storage and conveying devices 200 arranged in a three-dimensional manner, and the corresponding materials can be sent out to the target equipment according to the needs of use, which greatly improves the efficiency and flexibility of material conveying.

[0029] To improve the flexibility of feeding and discharging materials into the hopper 622, in this embodiment, the unloading trolley 500 is equipped with a lifting frame 621 that can move vertically. The hopper 622 is mounted on the lifting frame 621, and a first discharge chute 6241 that can extend or retract from below the discharge port is provided on the bottom side of the hopper 622. The lifting frame 621 can drive the hopper 622 to move up and down. When the transfer hopper 921 needs to open its discharge port to discharge materials into the hopper 622, the lifting frame 621 moves the hopper 622 downward, so that the hopper 622 is located below the transfer hopper 921. When it is necessary to add materials to the target equipment, the lifting frame 621 moves the hopper 622 upward, so that the hopper 622 is above the target equipment, so that the materials can be better fed into the target equipment.

[0030] There are various structural forms that drive the first discharge trough 6241 to move back and forth. For example, a linear drive can be used to drive the first discharge trough 6241 to move. In this embodiment, such as... Figure 2 and Figure 3 As shown, the lifting frame 621 is equipped with a first motor and a first synchronous pulley 6242. The first motor drives the first synchronous pulley 6242. A second synchronous pulley 6243 is provided on the outside of the hopper 622. A first synchronous belt 6244 is connected between the first synchronous pulley 6242 and the second synchronous pulley 6243. The first discharge chute 6241 is slidably connected to the outside of the hopper 622 and is connected to the first synchronous belt 6244. When the first motor drives the first synchronous pulley 6242 to rotate, the first discharge chute 6241 can be driven to extend or retract from below the discharge port through the first synchronous belt 6244. When material needs to be discharged, the first motor operates, driving the first synchronous pulley 6242 to rotate and transmitting power to the first synchronous belt 6244, causing the first synchronous belt 6244 to rotate on the first synchronous pulley 6242 and the second synchronous pulley 6243. Since the first discharge trough 6241 is connected to the first synchronous belt 6244, as the first motor drives the first synchronous belt 6244 to rotate forward or reverse, the first discharge trough 6241 can be driven to extend or retract from below the discharge port.

[0031] To extend the travel distance for guiding material out of the discharge port, in this embodiment, a second discharge trough 6245 is slidably connected to the outside of the first discharge trough 6241. A third synchronous pulley 6246 and a fourth synchronous pulley 6247 are spaced apart along the length of the first discharge trough 6241. A second synchronous belt 6248 is drivingly connected between the third synchronous pulley 6246 and the fourth synchronous pulley 6247. A fixing block is connected to the lifting frame 621. The fixing block is connected to one side of the second synchronous belt 6248, and the second discharge trough 6245 is connected to the other side of the second synchronous belt 6248. When the first discharge trough 6241 slides relative to the lifting frame 621, the second discharge trough 6245 can be extended or retracted from the first discharge trough 6241 by the second synchronous belt 6248. When the first discharge chute 6241 moves, since a fixed connection point is formed between one side of the second synchronous belt 6248 on the first discharge chute 6241 and the lifting frame 621, the second synchronous belt 6248 rotates around the fixed block as a fulcrum. For example, when the first discharge chute 6241 extends from below the discharge port, the second discharge chute 6245 can also extend relative to the first discharge chute 6241; when the first discharge chute 6241 retracts below the discharge port, the second discharge chute 6245 can also retract relative to the first discharge chute 6241. In this way, the first discharge chute 6241 and the second discharge chute 6245 can form a two-stage extension and retraction on the bottom side of the hopper 622. When extending, it can extend to a longer length, and when retracting, it can be further retracted to the bottom side of the hopper 622.

[0032] The baffle plate 623 can close or open the discharge port by moving in a straight line towards or away from it, or by rotating it. Specifically, the top side of the baffle plate 623 is hinged to the outside of the hopper 622. A rotary drive is provided on the lifting frame 621, which drives the baffle plate 623. The rotary drive can rotate the baffle plate 623 upward to open the discharge port or downward to close it. When transferring material into the hopper 622, the rotary drive causes the baffle plate 623 to rotate downward to close the discharge port, thereby preventing material from being discharged from the hopper 622. When it is necessary to discharge material from the hopper 622, the rotary drive causes the baffle plate 623 to rotate upward to open the discharge port, at which point the material can be discharged from the discharge port.

[0033] A drive structure is provided on the unloading trolley 500 to drive the lifting frame 621 to move up and down. Specifically, a vertical frame 510 is provided on the top side of the unloading trolley 500, and a lifting drive source is provided inside the vertical frame 510. The lifting frame 621 is slidably connected to the vertical frame 510, and the lifting drive source drives the lifting frame 621 to slide up and down. The lifting drive source provides a driving force for the lifting frame 621 to move up and down. When it is necessary to add material into the hopper 622, the lifting drive source drives the lifting frame 621 to move downward on the vertical frame 510, thereby lowering the height of the hopper 622 to facilitate adding material into the hopper 622. When it is necessary to pour the material in the hopper 622 to the target equipment, the lifting drive source drives the lifting frame 621 to move upward, thereby raising the hopper 622 to facilitate pouring the material in the hopper 622 to the target equipment through the discharge port.

[0034] The lifting drive source can be a cylinder, hydraulic cylinder, or other similar drive source. However, when a large driving stroke is required, it occupies a large space. Therefore, in this embodiment, the lifting drive source includes a second motor and a fifth synchronous pulley mounted on the vertical frame 510. Two fifth synchronous pulleys are spaced apart in the vertical direction. The second motor drives and connects to either of the fifth synchronous pulleys. A third synchronous belt is connected between the two fifth synchronous pulleys. The lifting frame 621 is connected to the third synchronous belt. When the second motor drives the fifth synchronous pulley to rotate, the third synchronous belt can drive the lifting frame 621 to slide up or down. The second motor can provide rotational driving force to the fifth synchronous pulley. By driving the fifth synchronous pulley to rotate, the third synchronous belt can rotate between the two fifth synchronous pulleys. At this time, the third synchronous belt can drive the lifting frame 621 to slide up or down, thereby adjusting the height of the hopper 622. This allows for a significant adjustment of the position of the hopper 622 in the vertical direction and makes the overall structure more compact.

[0035] The loading and unloading vehicles 500 are AGV trolleys, each equipped with drive wheels and steering wheels on its underside, enabling them to move between different devices.

[0036] The tilting mechanism has a drive structure that can rotate the tilting frame 911, specifically, as follows: Figure 8 and Figure 9As shown, the flipping mechanism includes a flipping motor 913 and a flipping shaft 914. The flipping shaft 914 is rotatably connected within the frame 100, passes through the flipping frame 911, and is synchronously connected to the flipping frame 911. The flipping motor 913 is connected to the frame 100 and drives the flipping shaft 914, allowing the flipping motor 913 to rotate along a horizontal axis. The flipping motor 913 provides a driving force for the flipping frame 911 to rotate along a horizontal axis through the flipping shaft 914. When the material tray is fed into the flipping frame 911, the opening of the material tray faces upward. After the pressure plate 912 presses the material tray firmly against the flipping frame 911, the flipping motor 913 drives the flipping frame 911 to rotate through the flipping shaft 914, causing the opening of the material tray to face downward. At this time, the material can be poured out of the material tray. After completion, the flipping motor 913 drives the flipping frame 911 to reverse and reset through the flipping shaft 914.

[0037] The flipping mechanism includes a drive structure that allows the pressure plate 912 to move up and down within the flipping frame 911. Specifically, a gantry frame 915 is mounted on the flipping frame 911, and a clamping drive component 916 is connected to the gantry frame 915. The clamping drive component 916 drives the pressure plate 912, allowing it to move up and down. For example, the clamping drive component 916 can be an electric screw, a pneumatic cylinder, or a hydraulic cylinder. The gantry frame 915 raises the clamping drive component 916 to the installation height of the flipping frame 911, providing the clamping drive component 916 with the driving force to move the pressure plate 912 up and down. Before the tray is placed in the frame, the clamping drive component 916 moves the pressure plate 912 upwards to the top of its stroke. After the tray is placed in the flipping frame 911, the clamping drive component 916 moves the pressure plate 912 downwards, pressing the tray firmly onto the flipping frame 911.

[0038] In the above embodiment, a fixed rod or plate structure can be directly provided inside the tilting frame 911 to support the material tray. To facilitate feeding the material tray into or out of the tilting frame 911, a feeding conveyor 917 is provided inside the tilting frame 911 below the pressure plate 912. When the material tray is fed into the tilting frame 911, the feeding conveyor 917 supports the material tray and assists in feeding the material tray into place. After the material tray is emptied, the feeding conveyor 917 sends the material tray back to the storage conveyor 200 to realize the recycling of the material tray. This improves the efficiency and convenience of feeding the material tray into or out of the tilting frame 911.

[0039] The opening and closing assembly is mainly used to open or close the discharge port. It has various structural forms; for example, it can directly use a butterfly valve or a gate valve. In this embodiment, the opening and closing assembly includes a sealing plate 922, a transmission rod 923, a transmission seat 924, and an opening and closing drive component 925. The opening and closing drive component 925 is connected to the outside of the transfer chamber 921 and drives the transmission seat 924. Two sealing plates 922 are rotatably connected to the two sides of the discharge port in the transfer chamber 921, and two transmission rods 923 and 924 are connected to the transmission seat 924. The bottom of the two sealing plates 922 are rotatably connected to each other at their respective positions. The tops of the two transmission rods 923 are rotatably connected to the transmission seat 924. The opening and closing drive 925 drives the transmission seat 924 to move downward and causes the two sealing plates 922 to rotate downward away from the discharge port. Alternatively, the opening and closing drive 925 drives the transmission seat 924 to move upward and causes the two sealing plates 922 to rotate upward and close the discharge port. In practical applications, the opening and closing drive 925 can be an electric lead screw, a cylinder, or a hydraulic cylinder. When there is no need to feed materials into the external equipment, the opening and closing drive 925 drives the transmission seat 924 to move upward to the top of its stroke. At this time, the transmission seat 924 drives the two sealing plates 922 to rotate upward through the two transmission rods 923 until they abut against the bottom side of the transfer chamber 921, thus closing the discharge port. When there is a need to feed materials into the external equipment, the opening and closing drive 925 drives the seat to move downward to the bottom of its stroke. At this time, the transmission seat 924 drives the two sealing plates 922 to rotate downward through the two transmission rods 923, opening the discharge port so that the materials in the transfer chamber 921 can fall into the equipment from the discharge port.

[0040] The transfer conveyor 310 can be a belt conveyor, chain conveyor, etc., but in this embodiment, the transfer conveyor 310 is a first roller conveyor. The first roller conveyor has multiple first conveying rollers 311 arranged at intervals along a straight direction, and a first conveying gap is formed between two adjacent first conveying rollers 311. A lifting drive 321 is provided below the transfer conveyor 310. The lifting drive 321 is driven to connect a stop bar 322, and the lifting drive 321 can drive the stop bar 322 to move up and down within one first conveying gap. In practical applications, the lifting drive 321 can be driven by a power source such as an electric screw, a pneumatic cylinder, or a hydraulic cylinder. When the material box needs to be conveyed on the transfer conveyor 310, the lifting drive 321 drives the baffle 322 to retract downward into the transfer conveyor 310, so that the baffle 322 does not interfere with or hinder the movement of the material box on the transfer conveyor 310. After the material box moves into place on the transfer conveyor 310, the lifting drive 321 drives the baffle 322 to protrude upward out of the transfer conveyor 310, preventing the material box from moving further on the transfer conveyor 310.

[0041] Similarly, the storage and conveying device 200 can be a belt conveyor, a chain conveyor, etc., but in this embodiment, the storage and conveying device 200 adopts a second roller conveyor.

[0042] In order to remove the tray from the transfer conveyor 310, in this embodiment, as follows: Figures 4 to 6 As shown, a material feeding mechanism is provided below the transfer conveying device 310. The material feeding mechanism includes a material feeding translation drive 410, a movable plate, and a lever 420. The material feeding translation drive 410 is mounted on the frame 100 and drives the movable plate. The frame 100 is located beside the transfer conveying device 310 and has a discharge port. The material feeding translation drive 410 can drive the movable plate to move closer to or away from the discharge port. Multiple levers 420 are provided on the movable plate along the conveying direction of the transfer conveying device 310. The multiple levers 420 pass upward through multiple first conveying gaps. The material feeding translation drive 410 can be driven by an electric screw, a cylinder, or a hydraulic cylinder. After the material in the hopper is emptied, the hopper can be sent out from the discharge port for recycling. Specifically, the empty hopper is transported back to the transfer conveyor 310. At this time, multiple levers 420 are located on the side of the transfer conveyor 310 away from the discharge port. The transfer conveyor 310 moves down to the discharge port, and the material shifting drive 410 drives multiple levers 420 to move towards the discharge port, pushing the hopper out of the discharge port. This is how the empty hopper can be removed.

[0043] The transfer mechanism includes a drive structure that can move the transfer conveyor 310 up and down. Specifically, the transfer mechanism includes a ring conveyor belt 331, a transfer motor, and a transmission wheel 332. The transfer motor and the ring conveyor belt 331 are installed within the frame 100. The transfer motor drives the transmission wheel 332, which is connected to the ring conveyor belt 331. A lifting plate is installed on the ring conveyor belt 331, and the transfer conveyor 310 is installed on the lifting plate. When it is necessary to move the transfer conveyor 310 up and down, the transfer motor drives the transmission wheel 332 to rotate, and the transmission wheel 332 transmits power to the ring conveyor belt 331, causing the ring conveyor belt 331 to rotate. When the ring conveyor belt rotates forward or backward, the lifting plate can drive the transfer conveyor 310 to move up or down.

[0044] In the above embodiments, the number of blocking units can be set only at the beginning or end of the conveying of the transfer conveyor 310. However, in order to limit the material box entering or exiting the transfer conveyor 310, in this embodiment, the blocking units are respectively provided on both sides of the transfer conveyor 310. When a material box needs to be fed into the transfer conveyor 310, the baffle 322 in the blocking unit on the side away from the storage conveyor 200 is moved down, and the baffle 322 in the blocking unit on the side close to the storage conveyor 200 is raised. When a material box needs to be fed into the storage conveyor 200, the baffle 322 in the blocking unit on the side close to the storage conveyor 200 is moved down, and the baffle 322 in the blocking unit on the side away from the storage conveyor 200 is raised.

[0045] After the material box is pushed out of the discharge port, it can be stacked and recycled. Specifically, for example... Figure 7 As shown, a discharge conveying device 700 is provided on the frame 100 at the side of the discharge port. A stacking mechanism 800 is provided on the frame 100 above the discharge conveying device 700. The stacking mechanism 800 has a transmission plate 810 that can move up and down. A lifting assembly is provided on the transmission plate 810. The lifting assembly has two lifting plates 820 that can move closer to or further away from each other. The material box output from the discharge port is placed on the discharge conveyor 700 and conveyed in a straight line on the discharge conveyor 700. When the material box moves past the stacking mechanism 800, the two lifting plates 820 in the lifting assembly are in a state of separation from each other. The transmission plate 810 moves downward, causing the two lifting plates 820 to move to positions on both sides of the material box. Then, the two lifting plates 820 move closer together, clamping onto both sides of the material box, pulling the transmission plate 810 upward, lifting the material box. At this time, the next material box can continue to be conveyed on the discharge conveyor 700 and moved to directly below the lifted material box. Then the transmission... As plate 810 moves downward, the two lifting plates 820 within the lifting assembly move away from each other, stacking the lifted boxes onto the boxes in the discharge conveyor 700, thus achieving vertical stacking of the boxes. This operation is repeated multiple times, allowing the boxes to be stacked directly after discharge. Once the boxes are stacked to the required height, the lifting assembly no longer lifts the boxes on the discharge conveyor 700, and the discharge conveyor 700 directly sends the stacked boxes outward. This allows for direct vertical stacking of the boxes during discharge, saving the steps of transferring and stacking the boxes after discharge, thereby improving overall production efficiency.

[0046] The lifting assembly has a drive structure that can drive two lifting box plates 820 to move closer or further apart. Specifically, the lifting assembly includes a connecting arm 830 and a lifting drive component 840. Two connecting arms 830 are spaced apart on the transmission plate 810, and the lifting drive component 840 is respectively mounted on the two connecting arms 830. The two lifting box plates 820 are respectively mounted on the two lifting drive components 840. The two lifting drive components 840 can drive the two lifting box plates 820 to move closer or further apart. In practical applications, the lifting drive component 840 can be an electric lead screw, a pneumatic cylinder, or a hydraulic cylinder, etc. When the transmission plate 810 drives the two connecting arms 830 to move down, the two lifting drive components 840 drive the two lifting box plates 820 to move away from each other. After the two lifting box plates 820 move down to their positions, the two lifting drive components 840 drive the two lifting box plates 820 to move closer to both sides of the box, so that the two lifting box plates 820 are locked to both sides of the box. At this time, the lifting and stacking of the box can be realized.

[0047] In the above embodiment, the two lifting drive components 840 can be directly connected to the two lifting box plates 820. In this embodiment, the two lifting drive components 840 are respectively driven and connected to the connecting plates 850. The bottom sides of the two connecting plates 850 are bent in a direction that approaches each other to form support edges 851. The two lifting box plates 820 are respectively hinged to the two connecting plates 850. The two lifting box plates 820 can be rotated upward or downward to abut against the two support edges 851. When the two lifting plates 820 move directly downward relative to the material box while they are close to each other, the two lifting plates 820 rotate upward under the pressure of the sides of the material box, avoiding the structure on both sides of the material box. When the two lifting plates 820 move down to the sides of the material box located in the discharge conveying device 700, the two lifting plates 820 can rotate downward under the action of gravity to reset and abut against the two support edges 851. When the transmission plate 810 moves upward, since the two support edges 851 provide limiting support for the two lifting plates 820, the lifting plates 820 can maintain the upward lifting state of the material box, thus improving the convenience of lifting and stacking the material box.

[0048] The stacking mechanism 800 includes a drive structure that can move the transmission plate 810 up and down. Specifically, the stacking mechanism 800 includes a stacking lifting drive 860 mounted on the frame 100. The stacking lifting drive 860 is connected to the transmission plate 810 and can move the transmission plate 810 up and down. In practical applications, the stacking lifting drive 860 can be an electric lead screw, a pneumatic cylinder, or a hydraulic cylinder. The stacking lifting drive 860 provides a driving force to the transmission plate 810 in the up-down direction, realizing the lifting and stacking of the material boxes.
