Description

Technical Field

[0001] This invention relates to a conveying device, and more particularly to a material loading machine. Background Technology

[0002] After processing and production, products need to be repackaged into pallets. For example, in the packaging of biscuits, after the biscuits are produced and packaged, they are conveyed out by a conveyor device. At this point, the biscuits need to be repackaged into pallets for subsequent overall packaging. Traditionally, the repackaging operation is done manually. Workers need to take the biscuits from the conveyor device, put them into the pallets, and then transfer the pallets containing the biscuits to another packaging device. This operation is inefficient, labor-intensive, and costly. Therefore, there is an urgent need for equipment that can automatically repackage materials such as biscuits into pallets. Summary of the Invention

[0003] The purpose of this invention is to provide a material loading machine 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:

[0005] A material loading and unloading machine includes: a material transfer mechanism comprising a feeding device, a transfer device, and a pushing assembly; the feeding device having a rotatable feeding conveyor belt, the transfer device having a rotatable transfer conveyor belt, the transfer conveyor belt having multiple trays arranged along its conveying direction, and the pushing assembly having a push plate movable back and forth between the feeding conveyor belt and one of the trays; a feeding device located beside the transfer device, the feeding device having a rotatable feeding conveyor belt, the feeding conveyor belt having multiple levers arranged along its conveying direction, and a feeding gap forming between adjacent levers; and a loading mechanism including a robotic arm and a mechanical gripper, the robotic arm having a movable end movable back and forth between the tray and the feeding gap, and the mechanical gripper being disposed on the movable end.

[0006] This technical solution has at least the following beneficial effects: The material transfer mechanism is used to separate materials that need to be packaged. Specifically, the materials to be transferred are placed on the feeding conveyor belt, and the feeding device transports the materials to be packaged. Driven by the feeding conveyor belt, the materials to be packaged move to the position facing the push plate. The push plate in the pushing assembly moves from the end of the limiting plate to the end of the tray, pushing the material into the tray of the transfer conveyor belt, thus separating and transferring the material. Then, the push rod retracts away from the end of the tray, while the transfer conveyor belt can continue to rotate, transferring the next empty tray to the position facing the push rod, in preparation for the next transfer of materials. In the tray feeding device, materials to be trayed can be... The packaging pallet is placed between two levers on the pallet-feeding conveyor belt. The pallet-feeding gap formed between the two levers can limit the movement of the packaging pallet, realizing the transfer of the packaging pallet. At this time, the movable end of the robotic arm drives the mechanical gripper to move to the pallet slot, pick up the material in the pallet slot, and transfer it to the packaging pallet located in the pallet-feeding gap, completing the loading of the material. Then the pallet-feeding conveyor belt continues to move, transporting the next packaging pallet into place to prepare for the next loading of material. In this way, by sorting and transferring the material conveyed out in an orderly manner into the pallet slot, and then taking it out from the pallet slot into the packaging pallet, the material sorting operation can be realized automatically, reducing manual operation and effectively improving the efficiency and stability of the material sorting operation.

[0007] As a further improvement to the above technical solution, a fixed plate is connected to the movable end, and multiple mechanical grippers are arranged on the fixed plate in the left-right direction. An adjustable distance device is provided on the fixed plate, which can adjust the distance between two adjacent mechanical grippers to be equal to the distance between two adjacent brackets or the distance between two adjacent levers. When there are multiple mechanical grippers, materials from multiple trays can be transferred simultaneously to packaging trays with multiple feeding gaps, thereby reducing the number of times the robotic arm moves. When the distance between two trays on the transfer conveyor belt is different from the distance between two levers on the feeding conveyor belt (i.e., the distance between two feeding gaps), an adjuster is needed to adjust the distance between the two mechanical grippers. Specifically, when multiple mechanical grippers need to grab materials from multiple trays simultaneously, the adjuster adjusts the distance between two adjacent mechanical grippers so that the distance between two adjacent mechanical grippers is equal to the distance between two adjacent trays. When multiple mechanical grippers need to place materials into multiple packaging trays simultaneously, the adjuster adjusts the distance between two adjacent mechanical grippers to be equal to the distance between two adjacent levers. This enables the single-pass feeding of multiple materials, improving work efficiency and providing convenient operation and high flexibility.

[0008] As a further improvement to the above technical solution, the adjusting device includes a sliding drive component, a parallel four-bar linkage, a synchronous belt, and synchronous pulleys. Two synchronous pulleys are spaced apart on the fixed plate in the left-right direction. The synchronous belt is synchronously connected to the two synchronous pulleys. Multiple mechanical grippers are slidably connected to the fixed plate in the left-right direction. The parallel four-bar linkage connects adjacent mechanical grippers. The leftmost mechanical gripper is synchronously connected to the top side of the synchronous belt, and the rightmost mechanical gripper is synchronously connected to the bottom side of the synchronous belt. The sliding drive component is connected to the fixed plate and drives the mechanical gripper located on the leftmost or rightmost side. When the distance between two mechanical grippers needs to be increased, the sliding drive moves the leftmost gripper to the left or the rightmost gripper to the right. Power is transmitted between adjacent grippers via a parallel four-bar linkage, which gradually unfolds, ultimately increasing the distance between them. Since the leftmost gripper is synchronously connected to the top of the timing belt, and the rightmost gripper is synchronously connected to the bottom, all grippers can slide gradually to the left and right, improving the accuracy of gripper positioning. Conversely, when the distance between two mechanical grippers needs to be decreased, the sliding drive moves the leftmost gripper to the right or the rightmost gripper to the left. Again, power is transmitted between adjacent grippers via a parallel four-bar linkage, which gradually folds and contracts, ultimately reducing the distance between them.

[0009] As a further improvement to the above technical solution, the material transfer mechanism is respectively provided on the front and rear sides of the feeding device. The movable end can move back and forth between the feeding gap and the trays of the two material transfer mechanisms. The material transfer mechanisms located on the front and rear sides of the feeding device simultaneously feed materials. After the movable end of the robotic arm transfers the tray of one material transfer mechanism to the feeding gap, it moves to the tray of the other material transfer mechanism to transfer the material into the feeding gap. This can better coordinate the production cycle, reduce the waiting time for material loading, and further improve the efficiency of material distribution operations.

[0010] As a further improvement to the above technical solution, the feeding device is provided with two limiting plates spaced apart above the feeding conveyor belt. A baffle assembly is provided on the downstream side of the feeding device, containing two baffle plates spaced vertically apart. These two baffle plates can move towards or away from the feeding conveyor belt. A pusher plate is located between the two baffle plates on the horizontal plane. Materials can be vertically arranged on the feeding conveyor belt, with the limiting plates on both sides limiting the material's position. Driven by the feeding conveyor belt, the material is conveyed towards the baffle assembly. At this time, the two baffle plates in the baffle assembly are close to the ends of the limiting plates, preventing the material between the two limiting plates from tipping over. When material needs to be transferred, the two baffle plates move away from the limiting plates, and the feeding conveyor belt in the feeding device also operates simultaneously, gradually pushing out the material arranged between the two limiting plates. When the baffle plates move to a set distance, the required amount of material between the two limiting plates is delivered, and the pusher plate in the pusher assembly pushes the material out from the ends of the limiting plates. The push rod moves towards the end of the tray, pushing the material into the tray of the transfer conveyor belt. After the material is discharged to the required quantity, it is transferred. At this time, the upper and lower baffles move towards the end of the limiting plate. Since the push plate is located between the two baffles on the same horizontal plane, the two baffles will not interfere with the push plate. The two baffles block the material at the end of the limiting plate to prevent the material from tipping over. Then the push rod can retract away from the end of the tray, while the transfer conveyor belt can continue to rotate, transferring the next empty tray to the push rod to prepare for the next material transfer. In this way, the material can be automatically and quantitatively transferred.

[0011] As a further improvement to the above technical solution, the material blocking assembly includes a first base plate, a first translation drive, and a first slide block. The first base plate is located downstream of the conveyor of the feeding device. The first slide block is slidably connected to the first base plate. The first translation drive can drive the first slide block to move closer to or away from the feeding conveyor belt. The material blocking plate located below is connected to the first slide block, and a connecting column connects the two material blocking plates. Two limiting plates form a material limiting area above the feeding conveyor belt, with the ends of the two limiting plates near the material blocking assembly as the discharge end. The first slide block can move on the first base plate in the direction of moving closer to or away from the discharge end. The first translation drive provides driving force for the sliding of the first slide block. Before feeding the material, the first translation drive drives the two material blocking plates to move closer to the discharge end through the first slide block. When quantitatively transferring the material, the first translation drive drives the two material blocking plates away from the discharge end through the first slide block, thereby forming a space between the two material blocking plates between the discharge ends for quantitatively discharging the material from the discharge end.

[0012] As a further improvement to the above technical solution, the feeding assembly includes a second base plate, a second translation drive, and a second slide block. The second base plate is located on a side perpendicular to the conveying direction of the feeding device. The second slide block is slidably connected to the second base plate. The second translation drive can move the second slide block closer to or away from the tray. The second slide block is connected to a push rod, and the push plate is connected to the end of the push rod. The second slide block can move on the second base plate in a direction closer to or away from the limiting plate. The second translation drive provides driving force for the sliding of the second slide block. After the required amount of material is discharged from the discharge end, the second translation drive drives the push plate closer to the tray through the second slide block, thereby quantitatively transferring the discharged material into the tray. During this process, the push rod on the second slide block can abut against the material near the end of the limiting plate, thereby preventing the material in the limiting plate from tipping over. After the material transfer is completed, the second translation drive drives the push plate away from the tray through the second slide block to prepare for the next material transfer.

[0013] As a further improvement to the above technical solution, the present invention also includes a feeding device located upstream of the conveying device of the feeding device, the feeding device having a rotatable feeding conveyor belt. A feeding device for feeding materials is also provided upstream of the conveying device of the feeding device. External materials can be fed onto the feeding conveyor belt via external equipment, and then transported along the feeding conveyor belt to the feeding conveyor belt of the feeding device. This configuration of two devices for material conveying allows for convenient integration with external equipment.

[0014] As a further improvement to the above technical solution, the feeding conveyor belt is inclined downwards along the direction close to the feeding device. The material conveyed on the feeding conveyor belt is fed into the feeding conveyor belt at an incline, which allows the material to be pressed onto the feeding conveyor belt under the action of gravity. This helps to prevent the material on the feeding conveyor belt from tipping over to the feeding conveyor belt, and better achieves material alignment.

[0015] As a further improvement to the above technical solution, the pallet feeding device is provided with side baffles above the pallet feeding conveyor belt, with two side baffles respectively spaced apart on both sides of the lever. When the pallet is placed into the pallet feeding gap, the two side baffles respectively block and limit the pallet on both sides. When the lever moves the pallet, it can drive the pallet to slide more stably along the rotation direction of the pallet feeding conveyor belt, thereby improving the stability of the conveying and transfer by the side baffles.

[0027] Reference Figure 1 , Figure 3 and Figure 4 A material loading and unloading machine includes a material transfer mechanism, a feeding device 700, and a loading mechanism. The material transfer mechanism includes a feeding device 100, a transfer device 300, and a pushing assembly 400. The feeding device 100 has a rotatable feeding conveyor belt, and the transfer device 300 has a rotatable transfer conveyor belt. Multiple trays 310 are provided on the transfer conveyor belt along its conveying direction. The pushing assembly 400 has a push plate 410 that can move back and forth between the feeding conveyor belt and one of the trays 310. In practical applications, the feeding device 100 can be a belt conveyor, and the rotatable conveyor belt within the belt conveyor is the feeding conveyor belt. The limiting plate 110 is connected to the fixed frame of the belt conveyor. Similarly, the transfer conveyor belt can be a belt conveyor, and the rotating conveyor belt inside the belt conveyor is the transfer conveyor belt. The feeding device 700 is located beside the transfer device 300. The feeding device 700 has a rotating feeding conveyor belt. Multiple levers 710 are arranged on the feeding conveyor belt along its conveying direction, and a feeding gap is formed between two adjacent levers 710. The loading mechanism includes a robotic arm 810 and a mechanical gripper 820. The robotic arm 810 has a movable end that can move back and forth between the tray 310 and the feeding gap. The mechanical gripper 820 is arranged on the movable end.

[0028] As described above, the material transfer mechanism is used to separate materials that need to be packaged. Specifically, the materials to be transferred are placed on the feeding conveyor belt, and the feeding device 100 transports the materials to be packaged. Driven by the feeding conveyor belt, the materials to be packaged move to the position facing the push plate 410. The push plate 410 in the pushing assembly 400 moves from the end of the limiting plate 110 to the end of the tray 310, pushing the materials into the tray 310 of the transfer conveyor belt, thus separating and transferring the materials. Then, the push rod 411 retracts away from the end of the tray 310, while the transfer conveyor belt can continue to rotate, transferring the next empty tray 310 to the position facing the push rod 411 to prepare for the next transfer of materials. In the tray feeding device 700, the materials to be loaded can be placed on the tray. The packaging pallet is placed between two levers 710 of the pallet-feeding conveyor belt. The pallet-feeding gap formed between the two levers 710 can limit the movement of the packaging pallet, realizing the transfer of the packaging pallet. At this time, the movable end of the robotic arm 810 drives the mechanical gripper 820 to move to the tray 310, pick up the material in the tray 310, and transfer it to the packaging pallet located in the pallet-feeding gap, completing the loading of the material. Then the pallet-feeding conveyor belt continues to move, transporting the next packaging pallet to the position to prepare for the next loading of the material. In this way, by sorting and transferring the material conveyed out in the arrangement to the tray 310, and then taking it out from the tray 310 to the packaging pallet, the automatic material sorting operation can be realized, reducing manual operation and effectively improving the efficiency and stability of the material sorting operation.

[0029] The robotic arm 810 is a drive source that can move the mechanical gripper 820 in three dimensions; for example, a six-axis robotic arm can be used. The robotic arm 810 can move only one mechanical gripper 820, but to further improve work efficiency, such as... Figure 2As shown, in this embodiment, a fixed plate 830 is connected to the movable end, and multiple mechanical grippers 820 are arranged on the fixed plate 830 in the left-right direction. An adjustable distance device is provided on the fixed plate 830, which can adjust the distance between two adjacent mechanical grippers 820 to be equal to the distance between two adjacent brackets 310 or the distance between two adjacent levers 710. When there are multiple mechanical grippers 820, materials in multiple trays 310 can be transferred simultaneously to packaging trays in multiple feeding gaps, thereby reducing the number of times the robotic arm 810 moves. When the distance between two trays 310 on the transfer conveyor belt is different from the distance between two levers 710 on the feeding conveyor belt, i.e., the distance between two feeding gaps, an adjusting device is needed to adjust the distance between the two mechanical grippers 820. Specifically, when multiple mechanical grippers 820 need to grab materials in multiple trays 310 simultaneously, the adjusting device adjusts the distance between two adjacent mechanical grippers 820 so that the distance between two adjacent mechanical grippers 820 is equal to the distance between two adjacent trays 310. When multiple mechanical grippers 820 need to place materials into multiple packaging trays simultaneously, the adjusting device adjusts the distance between two adjacent mechanical grippers 820 to be equal to the distance between two adjacent levers 710. This enables the single-time feeding of multiple materials, improving work efficiency, and is convenient to operate and highly flexible in use.

[0030] The distance adjuster is mainly used to adjust the distance between two adjacent mechanical grippers 820. For example, multiple cylinders, electric lead screws, or hydraulic cylinders can be installed on the fixed plate 830 to drive the mechanical grippers 820 to move. However, this results in a larger overall structure and higher production costs. Therefore, to simplify the overall structure, in this embodiment, the distance adjuster includes a sliding drive component 841, a parallel four-bar linkage 842, a synchronous belt 843, and synchronous pulleys 844. Two synchronous pulleys 844 are spaced apart on the fixed plate 830 in the left-right direction, and the synchronous belt 843 is synchronously connected to the two... The synchronous pulley 844 and the plurality of mechanical grippers 820 are slidably connected to the fixed plate 830 in the left-right direction. A parallel four-bar linkage 842 connects two adjacent mechanical grippers 820. The mechanical gripper 820 located on the leftmost side is synchronously connected to the top side of the synchronous belt 843, and the mechanical gripper 820 located on the rightmost side is synchronously connected to the bottom side of the synchronous belt 843. The sliding drive member 841 is connected to the fixed plate 830, and the sliding drive member 841 drives the mechanical gripper 820 located on the leftmost side or the rightmost side. When it is necessary to increase the distance between the two mechanical grippers 820, the sliding drive 841 drives the leftmost mechanical gripper 820 to move to the left or the rightmost mechanical gripper 820 to move to the right. At this time, the two adjacent mechanical grippers 820 transmit power through a parallel four-bar linkage 842. The parallel four-bar linkage 842 gradually unfolds, ultimately increasing the distance between the two adjacent mechanical grippers 820. Furthermore, since the leftmost mechanical gripper 820 is synchronously connected to the top side of the synchronous belt 843, and the rightmost mechanical gripper 820 is synchronously connected to the top side of the synchronous belt 843, the distance between the two adjacent mechanical grippers 820 increases. The bottom side of the stepper belt 843 can drive all mechanical grippers 820 to gradually slide to the left and right sides, improving the accuracy of positioning the mechanical grippers 820. When it is necessary to reduce the distance between two mechanical grippers 820, the sliding drive component 841 drives the leftmost mechanical gripper 820 to move to the right or the rightmost mechanical gripper 820 to move to the left. Similarly, power is transmitted between two adjacent mechanical grippers 820 through a parallel four-bar linkage 842. The parallel four-bar linkage 842 gradually folds and retracts, ultimately reducing the distance between two adjacent mechanical grippers 820.

[0031] In the above embodiments, there may be only one material transfer mechanism. However, in order to better coordinate the action rhythm and improve the overall production efficiency, in this embodiment, the material transfer mechanism is respectively provided on the front and rear sides of the feeding device 700. The movable end can move back and forth between the feeding gap and the trays 310 of the two material transfer mechanisms. The material transfer mechanisms located on the front and rear sides of the feeding device 700 simultaneously feed materials. After the movable end of the robotic arm 810 transfers the tray 310 of one material transfer mechanism to the feeding gap, it moves to the tray 310 of the other material transfer mechanism to transfer the material into the feeding gap. This can better coordinate the production rhythm, reduce the waiting time for material loading, and further improve the efficiency of material distribution operations.

[0032] To better arrange and transfer materials, such as Figure 5 As shown, in this embodiment, the feeding device 100 is provided with two limiting plates 110 spaced apart above the feeding conveyor belt. At this time, the two limiting plates 110 are connected to the fixed structure of the belt conveyor. A baffle assembly 200 is provided on the downstream side of the feeding device 100. The baffle assembly 200 has two baffle plates 210 spaced apart vertically. The two baffle plates 210 can move in the direction of approaching or moving away from the feeding conveyor belt. The push plate 410 is located between the horizontal planes where the two baffle plates 210 are located. Materials can be vertically arranged on the feeding conveyor belt, with limiting plates 110 on both sides limiting the materials on both sides. Driven by the feeding conveyor belt, the materials can be conveyed to the baffle assembly 200. At this time, the two baffle plates 210 in the baffle assembly 200 are close to the ends of the limiting plates 110 to prevent the materials located between the two limiting plates 110 from tipping over. When it is necessary to transfer the materials, the two baffle plates 210 move away from the limiting plates 110, and the feeding conveyor belt in the feeding device 100 also works at the same time, gradually pushing out the materials arranged between the two limiting plates 110. When the baffle plates 210 move to a set distance, the materials between the two limiting plates 110 are pushed out to the required quantity, and the pusher plate 410 in the pusher assembly 400 pushes the materials out of the limiting plates 110. The end moves towards the end of the tray 310, pushing the material into the tray 310 of the transfer conveyor belt, realizing the material discharge to the required quantity before transfer. At this time, the upper and lower baffles 210 move towards the end of the limiting plate 110. Since the push plate 410 is located between the horizontal planes of the two baffles 210, the two baffles 210 will not interfere with the push plate 410. The two baffles 210 block the material located at the end of the limiting plate 110 to prevent the material from tipping over. Then the push rod 411 can retract away from the end of the tray 310, while the transfer conveyor belt can continue to rotate, transferring the next empty tray 310 to the push rod 411 to prepare for the next material transfer. In this way, the material can be automatically and quantitatively transferred.

[0033] The baffle assembly 200 mainly has a drive source that can drive the upper and lower baffle plates 210 to move closer to or away from the limiting plate 110. It has various structural forms. In this embodiment, the baffle assembly 200 includes a first base plate 220, a first translation drive 230 and a first slide block 240. The first base plate 220 is located on the downstream side of the conveying device 100. The first slide block 240 is slidably connected to the first base plate 220. The first translation drive 230 can drive the first slide block 240 to move closer to or away from the feeding conveyor belt. The lower baffle plate 210 is connected to the first slide block 240. A connecting post 250 is connected between the two baffle plates 210. Two limiting plates 110 are arranged above the feeding conveyor belt to form a region for limiting the material. The ends of the two limiting plates 110 near the baffle assembly 200 are the discharge ends. The first slide block 240 can move on the first base plate 220 in the direction of approaching or moving away from the discharge end. The first translation drive 230 provides driving force for the sliding of the first slide block 240. Before feeding the material, the first translation drive 230 drives the two baffle plates 210 to approach the discharge end through the first slide block 240. When the material is quantitatively transferred, the first translation drive 230 drives the two baffle plates 210 away from the discharge end through the first slide block 240, so that the two baffle plates 210 form a space between the discharge ends that can quantitatively measure the material sent out from the discharge end.

[0034] In practical applications, the first translation drive 230 is mainly used to provide driving force for reciprocating movement in a straight direction. It has various structural forms, such as cylinders, hydraulic cylinders, or electric lead screws. In this embodiment, the first translation drive 230 can be driven by a synchronous belt 843. Specifically, a first motor is connected to the first base plate 220, and a first synchronous pulley 844 is installed on the first base plate 220. The first motor drives the first synchronous pulley 844, and a first synchronous belt 843 is connected to the outside of the first synchronous pulley 844. The first synchronous belt 843 is synchronously connected to the first slide block 240. The first motor drives the first synchronous belt 843 to rotate back and forth, thereby driving the first slide block 240 to move back and forth on the first base plate 220.

[0035] The feeding assembly 400 mainly has a drive source that can drive the push plate 410 to move closer to or away from the tray 310. In this embodiment, the feeding assembly 400 includes a second base plate 420, a second translation drive 430 and a second slide block 440. The second base plate 420 is located on one side perpendicular to the conveying direction of the feeding device 100. The second slide block 440 is slidably connected to the second base plate 420. The second translation drive can drive the second slide block 440 to move closer to or away from the tray 310. The second slide block 440 is connected to a push rod 411, and the push plate 410 is connected to the end of the push rod 411. The second slide block 440 can move on the second base plate 420 in a direction close to or away from the limiting plate 110. The second translation drive provides driving force for the sliding of the second slide block 440. After the required amount of material is discharged from the discharge end, the second translation drive drives the push plate 410 to approach the tray 310 through the second slide block 440, thereby quantitatively transferring the discharged material into the tray 310. During this process, the push rod 411 on the second slide block 440 can abut against the material near the end of the limiting plate 110, thereby preventing the material in the limiting plate 110 from tipping over. After the material transfer is completed, the second translation drive drives the push plate 410 away from the tray 310 through the second slide block 440 to prepare for the next material transfer.

[0036] In practical applications, the second translation drive is mainly used to provide the driving force for reciprocating movement along a straight line. It has various structural forms, such as cylinders, hydraulic cylinders, or electric lead screws. In this embodiment, the second translation drive can be in the form of synchronous belt 843 transmission. Specifically, a second motor is connected to the second base plate 420, and a second synchronous pulley 844 is installed on the second base plate 420. The second synchronous pulley 844 is driven by the second motor, and a second synchronous belt 843 is connected to the outside of the second synchronous pulley 844. The second synchronous belt 843 is synchronously connected to the second slide block 440. The second synchronous belt 843 is driven to reciprocate by the second motor, thereby driving the second slide block 440 to move back and forth on the second base plate 420.

[0037] When materials are arranged and conveyed, to prevent them from being pushed upwards due to compression, in this embodiment, a bracket 510 is provided on the side of the limiting plate 110, and a pressure plate 520 is connected to the bracket 510 above the feeding conveyor belt. When the materials move to a position between the two limiting plates 110 near the material blocking assembly 200 under the drive of the feeding conveyor belt, the pressure plate 520 abuts against the top of the materials, which can limit the height position of the materials and further improve the effect of aligning the materials between the two limiting plates 110.

[0038] The tray 310 forms a trough structure for holding materials. This trough structure extends perpendicular to the direction of movement of the transfer conveyor belt. When materials are pushed into the tray 310, in order to better position the materials within the tray 310, in this embodiment, a stop bar 311 is connected to the middle of the tray 310. When the pusher plate 410 pushes the materials into the tray 310, the stop bar 311 in the middle of the tray 310 can limit the stroke of the materials entering the tray 310, preventing the materials from excessively entering the tray 310, thereby improving the effect of aligning the materials transferred into the tray 310.

[0039] To improve the stability of pushing material into the tray 310, in this embodiment, guide edges 312 are respectively connected to both sides of the tray 310 near the limiting plate 110, and the two guide edges 312 gradually move away from each other in the direction close to the limiting plate 110. The two guide edges 312 form a guide area at the end of the tray 310 that gradually narrows towards the tray 310. In this way, when the material is pushed into the tray 310, it can smoothly enter between the two guide edges 312, and then, guided by the two guide edges 312 on both sides of the material, the material can be smoothly pushed into the tray 310.

[0040] External materials can be directly fed onto the feeding conveyor belt. To further improve the material arrangement effect, the present invention also includes a feeding device 600, which is located on the upstream side of the feeding device 100. The feeding device 600 has a rotating feeding conveyor belt. In practical applications, the feeding device 600 can be a belt conveyor, in which case the rotating conveyor belt inside the belt conveyor is the feeding conveyor belt. In addition, a width limiting plate is also provided above the feeding conveyor belt in the feeding device 600. Two width limiting plates are arranged at intervals along the conveying direction perpendicular to the feeding conveyor belt. The two width limiting plates limit the material on both sides respectively. One width limiting plate is longer than the other, which facilitates the entry of material on the shorter side. On the upstream side of the feeding device 100, there is also a feeding device 600 for feeding materials. External materials can be fed into the feeding conveyor belt through external equipment, and the materials are conveyed to the feeding conveyor belt of the feeding device 100 along the feeding conveyor belt. With two devices for conveying materials configured in this way, it is convenient to connect to external equipment for use.

[0041] The feeding conveyor belt can push materials horizontally, just like the loading conveyor belt. However, in this embodiment, the feeding conveyor belt is inclined downwards along the direction close to the loading device 100. The material conveyed on the feeding conveyor belt is fed into the loading conveyor belt at an incline, which allows the material to be pressed onto the loading conveyor belt under the action of gravity. This helps to prevent the material on the loading conveyor belt from tipping over to the feeding conveyor belt, and better achieves material alignment.

[0042] The pallet feeding device 700 can be a belt conveyor or a chain conveyor. To improve the efficiency of pallet feeding by the pallet feeding device 700, in this embodiment, the pallet feeding device 700 is provided with side baffles 720 above the pallet feeding conveyor belt, and the two side baffles 720 are respectively spaced apart on both sides of the lever 710. When the pallet is placed into the pallet feeding gap, the two side baffles 720 respectively block and limit the pallet on both sides. When the lever 710 moves the pallet, it can drive the pallet to slide more stably along the rotation direction of the pallet feeding conveyor belt, thereby improving the stability of the conveying and transfer of the side baffles 720.

[0043] For the feeding of packaging pallets to the pallet feeding device 700, the packaging pallets can be placed in by a person, or the stacked packaging pallets can be automatically placed in by an external device, such as a pallet sorting machine.

[0044] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
