Description

Technical Field

[0001] The invention relates to a conveying device, in particular to a material tray loading machine. Background Art

[0002] After the products are processed and produced, they need to be packaged in packaging trays. For example, for the packaging of biscuits, after the biscuits are produced and packaged, they are sent out by a conveying device. At this time, the biscuits need to be packaged in packaging trays for subsequent overall packaging. The traditional tray separation operation is performed manually. Workers need to take out the biscuits sent out by the conveying device and put them into the packaging tray, and then transfer the packaging tray filled with biscuits as a whole to another packaging equipment. Such operation is difficult to improve work efficiency, and the work intensity is high and the labor cost is high. Therefore, there is an urgent need for a device that can automatically package biscuits and other materials into packaging trays. Summary of the invention

[0003] The object of the present invention is to provide a material tray loading machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] A material loading and unloading machine comprises: a material transfer mechanism, including a loading device, a transfer device and a pushing assembly, the loading device has a rotatable loading conveyor belt, the transfer device has a rotatable transfer conveyor belt, a plurality of brackets are arranged on the transfer conveyor belt along its conveying direction, and the pushing assembly has a push plate that can move back and forth between the loading conveyor belt and one of the brackets; a feeding device, located beside the transfer device, the feeding device has a rotatable feeding conveyor belt, a plurality of levers are arranged on the feeding conveyor belt along its conveying direction, and a feeding gap is formed between two adjacent driving levers; a loading and unloading mechanism comprises a mechanical arm and a mechanical clamp, the mechanical arm has a movable end that can move back and forth between the bracket and the feeding gap, and the mechanical clamp is arranged on the movable end.

[0006] The technical solution has at least the following beneficial effects: the material transfer mechanism is used to separate the materials that need to be packaged. Specifically, the materials that need 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 opposite to the push plate, and the push plate in the pushing assembly moves from the end of the limit plate to the end of the bracket to push the materials into the bracket of the transfer conveyor belt, thereby separating and transferring the materials. Then the push rod retreats in the direction away from the end of the bracket, and the transfer conveyor belt can continue to rotate to transfer the next empty bracket to the push rod to prepare for the next transfer of materials. In the feeding device, the brackets that need to be loaded can be placed in the feeding device. The packaging tray is placed between the two levers of the tray feeding conveyor belt. The tray feeding gap formed between the two levers can limit the packaging tray and realize the transfer of the packaging tray. At this time, the movable end of the robotic arm drives the mechanical gripper to move to the bracket, clamps the material in the bracket, and transfers it to the packaging tray located in the tray feeding gap to complete the loading of the material. Then the tray feeding conveyor belt continues to move to transport the next packaging tray to prepare for the next loading of the material. In this way, the materials arranged and transported are divided and transferred to the bracket, and then taken out from the bracket into the packaging tray. Automatic material separation operation can be realized, manual operation can be reduced, and the efficiency and stability of material separation operation can be effectively improved.

[0007] As a further improvement of the above technical solution, a fixed plate is connected to the movable end, and a plurality of mechanical clamps are arranged on the fixed plate along the left and right directions. A distance adjuster is arranged on the fixed plate, and the distance adjuster can adjust the distance between two adjacent mechanical clamps to be equal to the distance between two adjacent brackets or the distance between two adjacent levers. When there are multiple mechanical grippers, materials in multiple brackets can be transferred to packaging trays in multiple tray delivery gaps at the same time, thereby reducing the number of activities of the mechanical arm. When the distance between two brackets set on the transfer conveyor belt is different from the distance between two levers set on the tray delivery conveyor belt, that is, the distance between the two tray delivery gaps, it is necessary to use a distance adjuster to adjust the distance between the two mechanical grippers. Specifically, when multiple mechanical grippers need to grab materials in multiple brackets at the same time, the distance 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 brackets. When multiple mechanical grippers need to put materials into multiple packaging trays at the same time, the distance adjuster adjusts the distance between two adjacent mechanical grippers to be equal to the distance between two adjacent levers. In this way, the separation operation of multiple materials can be realized at a single time, work efficiency is improved, and the operation is convenient and the use flexibility is high.

[0008] As a further improvement of the above technical solution, the distance adjuster includes a sliding drive, a parallelogram linkage, a synchronous belt and a synchronous wheel. Two synchronous wheels are arranged on the fixed plate at intervals in the left-right direction. The synchronous belt is synchronously connected to the two synchronous wheels. A plurality of mechanical clamps are slidably connected to the fixed plate in the left-right direction. The parallelogram linkage is connected between two adjacent mechanical clamps. The mechanical clamp located on the far left is synchronously connected to the top side of the synchronous belt, and the mechanical clamp located on the far right is synchronously connected to the bottom side of the synchronous belt. The sliding drive is connected to the fixed plate, and the sliding drive is drivingly connected to the mechanical clamp located on the far left or the far right. When the distance between the two mechanical grippers needs to be increased, the sliding drive component drives the mechanical gripper located on the far left to move to the left or the mechanical gripper located on the far right to move to the right. At this time, power is transmitted between the two adjacent mechanical grippers through a parallel four-bar linkage, and the parallel four-bar linkage gradually unfolds, eventually increasing the distance between the two adjacent mechanical grippers. Moreover, since the mechanical gripper located on the far left is synchronously connected to the top side of the synchronous belt, and the mechanical gripper located on the far right is synchronously connected to the bottom side of the synchronous belt, all the mechanical grippers can be driven to gradually slide to the left and right, thereby improving the accuracy of the positioning of the mechanical grippers. When the distance between the two mechanical grippers needs to be reduced, the sliding drive component drives the mechanical gripper located on the far left to move to the right or the mechanical gripper located on the far right to move to the left. Similarly, power is transmitted between the two adjacent mechanical grippers through a parallel four-bar linkage, and the parallel four-bar linkage gradually folds and contracts, eventually reducing the distance between the two adjacent mechanical grippers.

[0009] As a further improvement of the above technical solution, the material transfer mechanism is respectively arranged on the front and rear sides of the tray delivery device, and the movable end can move back and forth between the tray delivery gap and the brackets of the two material transfer mechanisms. The material transfer mechanisms located on the front and rear sides of the tray delivery device load materials at the same time, and the movable end of the robot arm transfers the bracket of one material transfer mechanism to the tray delivery gap, and then moves to the bracket of another material transfer mechanism to transfer the material to the tray delivery gap, so that the production rhythm can be better coordinated, the waiting time for material loading can be reduced, and the efficiency of material tray separation operation can be further improved.

[0010] As a further improvement of the above technical solution, the feeding device is located above the feeding conveyor belt and is provided with two limit plates at intervals, and a baffle assembly is provided on the downstream side of the feeding device, and the baffle assembly has two baffle plates spaced apart from each other, and the two baffle plates can move in the direction close to or away from the feeding conveyor belt, and the push plate is located between the horizontal planes where the two baffle plates are located. The material can be arranged vertically on the feeding conveyor belt, and the limit plates on both sides limit the two sides of the material respectively. Driven by the feeding conveyor belt, the material can be transported to the baffle assembly. At this time, the two baffle plates in the baffle assembly are close to the end of the limit plate to prevent the material between the two limit plates from dumping. When the material needs to be transferred, the two baffle plates move in the direction away from the limit plate, and the feeding conveyor belt in the feeding device also works at the same time to gradually push out the material arranged on the two limit plates. When the baffle plate moves to the set distance, the material between the two limit plates is sent out to the required amount, and the push plate in the push assembly pushes the material from the end of the limit plate. The push rod moves toward the end of the bracket to push the material into the bracket of the transfer conveyor belt, and the material is discharged to the required quantity before being transferred. At this time, the upper and lower baffle plates move toward the end of the limit plate. Since the push plate is located between the horizontal planes where the two baffle plates are located, the two baffle plates will not interfere with the push plate. The two baffle plates are used to block the material at the end of the limit plate to prevent the material from dumping. Then the push rod can retreat in the direction away from the end of the bracket, and the transfer conveyor belt can continue to rotate to transfer the next empty bracket to the push rod to prepare for the next transfer of material. In this way, the material can be automatically and quantitatively transferred.

[0011] As a further improvement of the above technical solution, the material blocking assembly includes a first substrate, a first translation drive and a first slide, the first substrate is located on the downstream side of the feeding device, the first slide is slidably connected to the first substrate, the first translation drive can drive the first slide to approach or move away from the feeding conveyor belt, the material blocking plate located below is connected to the first slide, and a connecting column is connected between the two material blocking plates. Two limit plates are arranged above the feeding conveyor belt to form an area for limiting the material, and the ends of the two limit plates close to the material blocking assembly are the discharge ends. The first slide can move on the first substrate in the direction of approaching or moving away from the discharge end, and the first translation drive provides driving force for the sliding of the first slide. Before the material is fed, the first translation drive drives the two material blocking plates to approach the discharge end through the first slide, and when the material is quantitatively transferred, the first translation drive drives the two material blocking plates away from the discharge end through the first slide, so that the two material blocking plates form a space between the discharge ends for quantitatively sending the material from the discharge end.

[0012] As a further improvement of the above technical solution, the push assembly includes a second substrate, a second translation drive and a second slide. The second substrate is located on a side perpendicular to the conveying direction of the loading device. The second slide is slidably connected to the second substrate. The second translation drive can drive the second slide to approach or move away from the bracket. The second slide is connected to a push rod, and the push plate is connected to the end of the push rod. The second slide can move on the second substrate in the direction of approaching or moving away from the limit plate. The second translation drive provides driving force for the sliding of the second slide. After the required amount of material is released from the discharge end, the second translation drive drives the push plate to approach the bracket through the second slide, thereby quantitatively transferring the released material into the bracket. In this process, the push rod on the second slide can abut against the material near the end of the limit plate, thereby preventing the material in the limit plate from dumping. After completing the material transfer, the second translation drive drives the push plate away from the bracket through the second slide to prepare for the next material transfer.

[0013] As a further improvement of the above technical solution, the present invention also includes a feeding device, which is located on the upstream side of the feeding device, and has a feeding conveyor belt that can rotate. A feeding device for feeding materials is also provided on the upstream side of the feeding device, and external materials can be fed into the feeding conveyor belt through an external device, and the materials are transported to the feeding conveyor belt of the feeding device along the feeding conveyor belt. In this way, two devices for conveying materials can be configured, which can be conveniently connected to the external device for use.

[0014] As a further improvement of the above technical solution, the feed conveyor belt is arranged to be inclined downward in the direction close to the loading device. The material conveyed on the feed conveyor belt is obliquely fed into the loading conveyor belt, so that the material can be pressed onto the loading conveyor belt under the action of gravity, which is conducive to preventing the material on the loading conveyor belt from tipping over to the feed conveyor belt, and better aligning the materials.

[0015] As a further improvement of the above technical solution, the tray delivery device is provided with a side baffle above the tray delivery conveyor belt, and two side baffles are respectively arranged at intervals on both sides of the lever. When the packaging tray is placed in the tray delivery gap, the two side baffles respectively block and limit the two sides of the packaging tray. When the lever moves the packaging tray, the packaging tray can be driven to slide more stably along the rotation direction of the tray delivery conveyor belt, thereby improving the stability of the side baffle conveying and transfer.

[0027] Reference Figure 1 , Figure 3 and Figure 4 A material loading machine includes a material transfer mechanism, a feeding device 700 and a loading mechanism, wherein the material transfer mechanism includes a loading device 100, a transfer device 300 and a pushing assembly 400, the loading device 100 has a rotatable loading conveyor belt, the transfer device 300 has a rotatable transfer conveyor belt, a plurality of brackets 310 are arranged on the transfer conveyor belt along its conveying direction, and the pushing assembly 400 has a push plate 410 that can move back and forth between the loading conveyor belt and one of the brackets 310. In practical applications, the loading device 100 can adopt a belt conveyor, and the rotating conveyor belt in the belt conveyor is the loading conveyor belt. At this time, the two The limit plate 110 is connected to the fixed frame of the belt conveyor. Similarly, the transfer conveyor belt can adopt a belt conveyor, and the conveyor belt that rotates in the belt conveyor is the transfer conveyor belt; the support delivery device 700 is located next to the transfer device 300, and the support delivery device 700 has a rotatable support delivery conveyor belt. A plurality of levers 710 are arranged on the support delivery conveyor belt along its conveying direction, and a support delivery gap is formed between two adjacent levers 710; the loading mechanism includes a mechanical arm 810 and a mechanical clamp 820, and the mechanical arm 810 has a movable end that can move back and forth between the bracket 310 and the support delivery gap, and the mechanical clamp 820 is arranged on the movable end.

[0028] As can be seen from the above, the material transfer mechanism is used to separate the materials that need to be packaged. Specifically, the materials that need 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 a position opposite to the push plate 410, and the push plate 410 in the pushing assembly 400 moves from the end of the limit plate 110 to the end of the bracket 310 to push the materials into the bracket 310 of the transfer conveyor belt, thereby separating and transferring the materials. Then the push rod 411 retreats in a direction away from the end of the bracket 310, and the transfer conveyor belt can continue to rotate to transfer the next empty bracket 310 to the push rod 411 to prepare for the next transfer of materials. In the feeding device 700, the brackets that need to be loaded can be placed The packaging tray is placed between the two levers 710 of the tray feeding conveyor belt. The tray feeding gap formed between the two levers 710 can limit the packaging tray to realize the transfer of the packaging tray. At this time, the movable end of the mechanical arm 810 drives the mechanical clamp 820 to move to the bracket 310, clamps the material in the bracket 310, and transfers it to the packaging tray located in the tray feeding gap to complete the loading of the material. Then the tray feeding conveyor belt continues to move to transport the next packaging tray to prepare for the next loading of the material. In this way, by transferring the arranged and transported materials into the bracket 310, and then taking them out of the bracket 310 and putting them into the packaging tray, the material separation operation can be realized, manual operation can be reduced, and the efficiency and stability of the material separation operation can be effectively improved.

[0029] The robot arm 810 is a driving source that can drive the mechanical gripper 820 to move in three-dimensional directions. For example, a six-axis robot arm can be used. The robot arm 810 can only drive one mechanical gripper 820 to move. In order to further improve work efficiency, Figure 2As shown, in this embodiment, a fixed plate 830 is connected to the movable end, and a plurality of mechanical clamps 820 are arranged on the fixed plate 830 along the left and right directions. A distance adjuster is arranged on the fixed plate 830, and the distance adjuster can adjust the distance between two adjacent mechanical clamps 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 brackets 310 can be transferred to packaging trays in multiple tray delivery gaps at the same time, thereby reducing the number of activities of the mechanical arm 810. When the distance between two brackets 310 set on the transfer conveyor belt is different from the distance between two levers 710 set on the tray delivery conveyor belt, that is, the distance between the two tray delivery gaps, it is necessary to use a distance adjuster to adjust the distance between the two mechanical grippers 820. Specifically, when multiple mechanical grippers 820 need to grab materials in multiple brackets 310 at the same time, the distance adjuster 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 brackets 310. When multiple mechanical grippers 820 need to put materials into multiple packaging trays at the same time, the distance adjuster adjusts the distance between two adjacent mechanical grippers 820 to be equal to the distance between two adjacent levers 710. In this way, multiple materials can be separated at a time, work efficiency is improved, and the operation is convenient and flexible.

[0030] The distance adjuster is mainly used to adjust the distance between two adjacent mechanical clamps 820. For example, multiple cylinders, electric screws or hydraulic cylinders and other driving sources can be installed on the fixed plate 830 to drive the mechanical clamps 820 to move. In this case, the overall structure is large and the production cost is high. Therefore, in order to simplify the overall structure, in this embodiment, the distance adjuster includes a sliding drive member 841, a parallel four-link 842, a synchronous belt 843 and a synchronous wheel 844. Two synchronous wheels 844 are arranged on the fixed plate 830 at intervals along the left and right directions. The synchronous belt 843 is synchronously connected to the two The synchronous wheels 844, the multiple mechanical grippers 820 are slidably connected to the fixed plate 830 along the left and right directions, the parallel four-link 842 is connected between two adjacent mechanical grippers 820, the mechanical gripper 820 located on the far left is synchronously connected to the top side of the synchronous belt 843, and the mechanical gripper 820 located on the far right 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 is drivingly connected to the mechanical gripper 820 located on the far left or the far right. When the distance between the two mechanical grippers 820 needs to be increased, the sliding drive member 841 drives the mechanical gripper 820 located on the far left to move to the left or the mechanical gripper 820 located on the far right to move to the right. At this time, the power is transmitted between the two adjacent mechanical grippers 820 through the parallel four-link 842, and the parallel four-link 842 gradually expands, eventually increasing the distance between the two adjacent mechanical grippers 820. In addition, since the mechanical gripper 820 located on the far left is synchronously connected to the top side of the synchronous belt 843, the mechanical gripper 820 located on the far right is synchronously connected to the top side of the synchronous belt 843. The bottom side of the step belt 843 can drive all the mechanical grippers 820 to slide gradually to the left and right sides, thereby improving the accuracy of positioning the mechanical grippers 820; when the distance between the two mechanical grippers 820 needs to be reduced, the sliding drive member 841 drives the mechanical gripper 820 located on the far left to move to the right or the mechanical gripper 820 located on the far right to move to the left. Similarly, power is transmitted between two adjacent mechanical grippers 820 through the parallel four-bar linkage 842, and the parallel four-bar linkage 842 gradually folds and contracts, ultimately reducing the distance between the two adjacent mechanical grippers 820.

[0031] In the above embodiment, the number of material transfer mechanisms can be only one, and in order to better coordinate the action rhythm and improve the overall production efficiency, in this embodiment, the material transfer mechanisms are respectively provided on the front and rear sides of the support feeding device 700, and the movable end can move back and forth between the support feeding gap and the brackets 310 of the two material transfer mechanisms. The material transfer mechanisms located on the front and rear sides of the support feeding device 700 load materials at the same time, and the movable end of the mechanical arm 810 transfers the bracket 310 of one material transfer mechanism to the support feeding gap, and then moves to the bracket 310 of another material transfer mechanism to transfer the material to the support feeding gap, so that the production rhythm can be better coordinated, the waiting time for material loading can be reduced, and the efficiency of the material separation operation can be further improved.

[0032] In order to better arrange and transfer materials, such as Figure 5 As shown, in this embodiment, the feeding device 100 is located above the feeding conveyor belt and has two limit plates 110 spaced apart. At this time, the two limit plates 110 are connected to the fixed structure of the belt conveyor. A material blocking assembly 200 is provided on the downstream side of the feeding device 100. The material blocking assembly 200 has two material blocking plates 210 spaced apart up and down. The two material blocking plates 210 can move in the direction of approaching or moving away from the feeding conveyor belt, and the push plate 410 is located between the horizontal planes where the two material blocking plates 210 are located. The materials can be arranged vertically on the feeding conveyor belt, and the limiting plates 110 on both sides limit the two sides of the materials respectively. Driven by the feeding conveyor belt, the materials can be conveyed to the blocking assembly 200. At this time, the two blocking plates 210 in the blocking assembly 200 are close to the ends of the limiting plates 110 to prevent the materials between the two limiting plates 110 from dumping. When the materials need to be transferred, the two blocking 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 to gradually push out the materials arranged on the two limiting plates 110. When the blocking plates 210 move to the set distance, the materials between the two limiting plates 110 are sent out to reach the required amount, and the pushing plates 410 in the pushing assembly 400 push the materials from the limiting plates 110. The end moves toward the end of the bracket 310, pushing the material into the bracket 310 of the transfer conveyor belt, and transferring the material after discharging the material to the required quantity. At this time, the upper and lower baffle plates 210 move toward the end of the limiting plate 110. Since the push plate 410 is located between the horizontal planes where the two baffle plates 210 are located, the two baffle plates 210 will not interfere with the push plate 410. The two baffle plates 210 are used to block the material located at the end of the limiting plate 110 to prevent the material from dumping. Then the push rod 411 can retreat in the direction away from the end of the bracket 310, and the transfer conveyor belt can continue to rotate, transferring the next empty bracket 310 to the push rod 411, in preparation for the next transfer of the material, so that the material can be automatically and quantitatively transferred.

[0033] The material blocking assembly 200 mainly has a driving source that can drive the upper and lower material blocking plates 210 to approach or move away from the limit plate 110. Its structural forms are various. In the present embodiment, the material blocking assembly 200 includes a first substrate 220, a first translation drive 230 and a first slide 240. The first substrate 220 is located on the downstream conveying side of the feeding device 100. The first slide 240 is slidably connected to the first substrate 220. The first translation drive 230 can drive the first slide 240 to approach or move away from the feeding conveyor belt. The material blocking plate 210 located below is connected to the first slide 240. A connecting column 250 is connected between the two material blocking plates 210. Two limit plates 110 are arranged above the loading conveyor belt to form an area for limiting the material, with the ends of the two limit plates 110 close to the material blocking assembly 200 as the discharge end. The first slide 240 can move on the first base plate 220 in a direction close to or away from the discharge end, and the first translation drive 230 provides driving force for the sliding of the first slide 240. Before loading the material, the first translation drive 230 drives the two material blocking plates 210 to approach the discharge end through the first slide 240. When the material is quantitatively transferred, the first translation drive 230 drives the two material blocking plates 210 away from the discharge end through the first slide 240, so that a space is formed between the two material blocking plates 210 for quantitatively sending the material from the discharge end.

[0034] In practical applications, the first translation drive 230 is mainly used to provide a driving force for reciprocating movement in a linear direction, and its structural forms include various forms, for example, a pneumatic cylinder, a hydraulic cylinder or an electric screw, etc. In the present embodiment, the first translation drive 230 can be driven by a synchronous belt 843. Specifically, a first motor is connected to the first substrate 220, and a first synchronous wheel 844 is installed on the first substrate 220. The first synchronous wheel 844 is connected by the first motor, and the first synchronous belt 843 is connected to the outer side of the first synchronous wheel 844. The first synchronous belt 843 is synchronously connected to the first slide 240, and the first synchronous belt 843 is driven to reciprocate by the first motor, thereby driving the first slide 240 to move back and forth on the first substrate 220.

[0035] The pushing assembly 400 mainly has a driving source that can drive the pushing plate 410 to approach or move away from the bracket 310. In this embodiment, the pushing assembly 400 includes a second substrate 420, a second translation driving member 430 and a second slide 440. The second substrate 420 is located on a side perpendicular to the conveying direction of the loading device 100. The second slide 440 is slidably connected to the second substrate 420. The second translation drive can drive the second slide 440 to approach or move away from the bracket 310. The second slide 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 440 can move on the second base plate 420 in the direction close to or away from the limit plate 110, and the second translation drive provides driving force for the sliding of the second slide 440. After the required amount of material is released from the discharge end, the second translation drive drives the push plate 410 to approach the bracket 310 through the second slide 440, so as to transfer the released material into the bracket 310 in a quantitative manner. During this process, the push rod 411 on the second slide 440 can be against the material close to the end of the limit plate 110, so as to prevent the material in the limit plate 110 from dumping. After completing the material transfer, the second translation drive drives the push plate 410 away from the bracket 310 through the second slide 440 to prepare for the next material transfer.

[0036] In practical applications, the second translation drive is mainly used to provide a driving force for reciprocating movement in a linear direction, and its structural forms include various types, for example, a pneumatic cylinder, a hydraulic cylinder or an electric screw, etc. In the present embodiment, the second translation drive can be driven by a synchronous belt 843. Specifically, a second motor is connected to the second substrate 420, and a second synchronous wheel 844 is installed on the second substrate 420. The second synchronous wheel 844 is connected by a second motor, and the second synchronous belt 843 is connected to the outer side of the second synchronous wheel 844. The second synchronous belt 843 is synchronously connected to the second slide 440, and the second synchronous belt 843 is driven to reciprocate by the second motor, thereby driving the second slide 440 to move back and forth on the second substrate 420.

[0037] When the materials are arranged and sent out, in order to prevent the materials from being pushed upward due to squeezing, in this embodiment, a bracket 510 is provided on the side of the limit plate 110, and the bracket 510 is connected to a pressing plate 520 at a position above the feeding conveyor belt. When the materials move to a position between the two limit plates 110 and close to the material blocking assembly 200 under the drive of the feeding conveyor belt, the pressing plate 520 abuts against the top side of the materials, and the height position of the materials can be limited, further improving the effect of aligning the materials between the two limit plates 110.

[0038] A slot structure for holding materials is formed in the bracket 310, and the slot structure extends in a direction perpendicular to the movement direction of the transfer conveyor belt. When the material is pushed into the bracket 310, in order to better position the material in the bracket 310, in this embodiment, a stopper 311 is connected to the middle of the bracket 310. When the push plate 410 pushes the material into the bracket 310, the stopper 311 in the middle of the bracket 310 can limit the travel of the material into the bracket 310, preventing the material from excessively entering the bracket 310, thereby improving the effect of aligning the material transferred to the bracket 310.

[0039] In order to improve the stability of pushing the material into the bracket 310, in this embodiment, the bracket 310 is connected to guide edges 312 on both sides close to 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 bracket 310 that gradually narrows toward the bracket 310, so that when the material is pushed into the bracket 310, it can smoothly enter between the two guide edges 312, and then along the guidance of the two guide edges 312 on both sides of the material, the material can be smoothly pushed into the bracket 310.

[0040] External materials can be directly fed to the feeding conveyor belt, and in order to further improve the effect of material arrangement, the present invention also includes a feeding device 600, which is located on the upstream side of the feeding device 100, and the feeding device 600 has a rotatable feeding conveyor belt. In practical applications, the feeding device 600 can adopt a belt conveyor, and the conveyor belt rotating in the belt conveyor is the feeding conveyor belt. In addition, the feeding device 600 is located above the feeding conveyor belt and a limited width plate is also provided. Two limited width plates are arranged at intervals along the conveying direction perpendicular to the feeding conveyor belt. The two limited width plates limit the two sides of the material respectively. One limited width plate is longer, and the other limited width plate is longer, so it is convenient to enter the material on the shorter side. A feeding device 600 for feeding materials is also provided on the upstream side of the feeding device 100. External materials can be fed into the feeding conveyor belt through external equipment, and the materials are transported to the feeding conveyor belt of the feeding device 100 along the feeding conveyor belt. In this way, two devices for conveying materials are configured, which can be conveniently connected to external equipment for use.

[0041] The feeding conveyor belt can push the material horizontally like the loading conveyor belt, and in this embodiment, the feeding conveyor belt is arranged obliquely downward in the direction close to the loading device 100. The material conveyed on the feeding conveyor belt is obliquely fed into the loading conveyor belt, so that the material can be pressed onto the loading conveyor belt under the action of gravity, which is helpful to prevent the material on the loading conveyor belt from falling onto the feeding conveyor belt, and better realize the alignment of the material.

[0042] The tray delivery device 700 may be a belt conveyor or a chain conveyor. In order to improve the efficiency of the tray delivery device 700 in delivering the packaging tray, in this embodiment, the tray delivery device 700 is provided with a side baffle 720 located above the tray delivery conveyor, and two side baffles 720 are respectively arranged at intervals on both sides of the lever 710. When the packaging tray is placed in the tray delivery gap, the two side baffles 720 respectively block and limit the two sides of the packaging tray. When the lever 710 moves the packaging tray, it can drive the packaging tray to slide more stably along the rotation direction of the tray delivery conveyor, thereby improving the stability of the side baffles 720 in conveying and transferring.

[0043] The loading of the packaging tray into the tray feeding device 700 may be done by a person putting the packaging tray in, or by an external device automatically putting the stacked packaging tray in, such as using a tray sorting machine.

[0044] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
