Description

Technical Field

[0001] The present invention relates to the technical field of egg tray packing equipment, in particular to a fully automatic egg tray separation and packing equipment and a control method for realizing automatic separation, transmission and packing of egg trays. Background Art

[0002] In the egg production and processing industry, egg trays are important tools for carrying eggs, and their separation and packing operations are key links in the production process.

[0003] Traditional methods of separating and packing egg trays rely heavily on manual labor. This is not only inefficient and unable to meet the demands of large-scale production, but also labor-intensive and prone to operator fatigue, which in turn affects product quality and production safety. While some semi-automatic egg tray handling equipment has emerged on the market, these devices suffer from insufficient automation, such as unstable egg tray separation, cumbersome carton handling procedures, and low precision in matching egg trays and cartons. This makes it difficult to fully automate the entire egg tray process, from separation to packing, and makes it difficult to meet the efficient and precise production requirements of modern poultry egg producers. Summary of the Invention

[0100] Example 1:

[0101] Please refer to Figures 1-17 This embodiment provides a fully automatic egg tray separation and packing device, comprising:

[0102] The frame 10 has an egg tray feed port 11 on one side, and a carton feed port 12 and a carton discharge port 13 on two opposite sides adjacent to the egg tray feed port 11.

[0103] The egg tray feeding mechanism 20 is installed outside the egg tray feeding port 11 of the frame 10 and is configured to transport the inverted egg tray stack to the egg tray separation position and limit the egg tray stack;

[0104] The egg tray separation and transfer mechanism 30 is installed in the frame 10 and is configured to separate a single egg tray from the egg tray pile in the storage state and transfer it to the transfer waiting position;

[0105] The egg tray transport waiting mechanism 40 is installed in the frame 10 and is configured to receive and temporarily store the separated egg trays, waiting for the packing instruction;

[0106] The egg tray grabbing and boxing mechanism 50 is installed in the frame 10 and is configured to grab the egg tray and transfer it to the corresponding carton;

[0107] A carton identification, blocking, and supporting mechanism 60 is installed in the frame 10 and is located between the carton feed port 12 and the carton discharge port 13. It is configured to convey cartons, identify cartons, block cartons, and support the top opening of the carton;

[0108] The central control system 70 is electrically connected to the egg tray loading mechanism 20, the egg tray separation and transfer mechanism 30, the egg tray transmission and waiting mechanism 40, the egg tray grabbing and packing mechanism 50, and the carton identification, blocking and supporting mechanism.

[0109] On the basis of the above structure, during the working process,

[0110] The inverted egg tray stack is placed on the feeding end of the egg tray feeding mechanism 20, and the egg tray feeding mechanism 20 is started to transport the egg tray stack to the egg tray separation position through the conveying device 22, and the egg tray stack is limited and fixed by the limiting structure.

[0111] The egg tray separation and transfer mechanism 30 starts to work. The egg tray separation and transfer mechanism 30 separates a single egg tray from the egg tray pile, and then transfers the separated egg tray to the delivery waiting position of the egg tray delivery waiting mechanism 40 .

[0112] The egg tray transport waiting mechanism 40 receives the egg trays transferred by the egg tray separation and transfer mechanism 30 and temporarily stores the egg trays on the conveyor belt, waiting for a packing instruction from the central control system.

[0113] The carton enters from the carton feed port 12, and the roller conveying assembly of the carton identification and blocking box support mechanism 60 transports the carton to the designated position. The carton identification device identifies the position of the carton. When the carton reaches the appropriate position, the blocking device blocks and fixes the carton, and then the opening device opens the top opening of the carton.

[0114] Egg tray grabbing and packing: The central control system 70 issues instructions to control the egg tray grabbing and packing mechanism 50 according to the position of the carton and the status of the egg tray. The egg tray grabbing and packing mechanism 50 accurately grabs the egg tray in the egg tray transfer waiting mechanism 40 and transfers the egg tray to the corresponding carton, completing the egg tray packing operation.

[0115] After the packing is completed, the carton identification blocking mechanism 60 is unblocked and the carton containing the egg tray is transported to the carton discharge port 13, completing the entire egg tray separation and packing process, waiting for subsequent packaging, transportation and other processes.

[0116] In this way, the present invention realizes the automation of the entire egg tray process, from feeding, separation, transmission, grabbing and packing to carton conveying, identification, blocking and supporting the carton, without the need for human intervention, greatly improving production efficiency, reducing labor costs, and also reducing errors and quality problems caused by manual operation. The egg tray feeding mechanism 20, egg tray separation and transfer mechanism 30, egg tray transmission and waiting mechanism 40, egg tray grabbing and packing mechanism 50, and carton identification and blocking and supporting mechanism 60 can quickly and stably complete their respective tasks, greatly shortening the time for egg tray separation and packing, and meeting the needs of large-scale production. Through the precise control of the central control system 70, the egg tray grabbing and packing mechanism 50 can accurately place the egg tray into the carton, and the carton identification and blocking and supporting mechanism 60 can ensure that the carton is in the appropriate position and state, ensuring the accuracy of egg tray packing and reducing damage and misalignment of the egg tray during the packing process.

[0117] In the first aspect of the present invention, as a preferred embodiment, the egg tray feeding mechanism 20 includes a first support frame 21, a conveying device 22 mounted on the first support frame 21, and a feeding blocking mechanism 23 mounted at an egg tray separation position of the first support frame 21;

[0118] The loading blocking mechanism 23 includes a door-shaped mounting frame 231, a pressing mechanism 232 and two blocking components 233;

[0119] The door-shaped mounting frame 231 is mounted across the first supporting frame 21;

[0120] The pressing mechanism 232 includes a first lifting drive mechanism 2321 mounted on the crossbeam of the door-shaped mounting frame 231 and a pressing member 2322 mounted on the output end of the first lifting drive mechanism 2321;

[0121] Two blocking assemblies 233 are symmetrically mounted on two vertical beams of the door-shaped mounting frame 231. The blocking assemblies 233 include a first longitudinal driving mechanism 2331 and a telescopic member 2332 mounted on the output end of the first longitudinal driving mechanism 2331.

[0122] The first lifting drive mechanism 2321 drives the pressing member 2322 to lift vertically to compress or release the egg tray stack, and the two first longitudinal drive mechanisms 2331 synchronously drive the two telescopic members 2332 to move horizontally and longitudinally toward or away from each other to limit or release the front of the egg tray stack.

[0123] Specifically, the door-shaped mounting frame 231 is arranged across the first supporting frame 21. Its structural design not only facilitates the installation of the pressing mechanism 232 and the blocking assembly 233, but also provides sufficient space for their operation.

[0124] Specifically, the conveying device 22 can adopt a chain-driven conveying form.

[0125] Specifically, the first lifting drive mechanism 2321 can employ a common linear drive device, such as a pneumatic cylinder. When the device is activated and detects that the egg tray stack has reached the designated position, the control system sends a signal to the pneumatic cylinder. The piston within the cylinder, under the action of compressed air, moves downward, driving the pressure member 2322 downward vertically. The pressure member 2322 is typically made of a flexible material, such as rubber. This provides sufficient pressure to prevent the stack from shaking during the separation process while also avoiding physical damage to the egg trays. During the separation process, the pressure member 2322 compresses the adjacent egg tray to be separated, preventing it from being dragged out during the separation process. Furthermore, when a single egg tray is separated and the stack needs to be released to allow subsequent egg trays to enter the separation position, the pneumatic cylinder reverses its motion, causing the piston to drive the pressure member 2322 upward, releasing the pressure on the stack.

[0126] Specifically, the first longitudinal drive mechanism 2331 can also utilize a linear drive component, such as a pneumatic cylinder. When the egg tray stack reaches the separation position, the control system simultaneously sends commands to the two first longitudinal drive mechanisms 2331, causing the two cylinder sliders to operate synchronously, driving the telescopic members 2332 to move horizontally and longitudinally toward each other. The telescopic members 2332 can be designed as baffles of a certain width. When they move toward each other until they contact the egg tray stack, they can restrain the position of the egg tray stack from the front, preventing horizontal displacement and ensuring that the egg tray separation and transfer mechanism 30 can accurately separate individual egg trays from the stack. When an egg tray is separated and a new egg tray needs to be added to the separation position, the first longitudinal drive mechanism 2331 activates again, driving the telescopic members 2332 to move backward, releasing the front restraint on the egg tray stack. The conveying device 22 can then transport the new egg tray stack forward a certain distance. The telescopic members 2332 then move toward each other again, restraining the new egg tray stack. This cycle repeats, achieving continuous loading and separation of egg trays.

[0127] Specifically, the first longitudinal drive mechanism 2331 can also utilize a linear drive component, such as a pneumatic cylinder. When the egg tray stack reaches the separation position, the control system simultaneously sends commands to the two first longitudinal drive mechanisms 2331, causing the two pneumatic cylinders or electric sliders to operate synchronously, driving the telescopic members 2332 to move horizontally and longitudinally toward each other. The telescopic members 2332 can be designed as baffles of a certain width. When they move toward each other until they contact the egg tray stack, they can restrain the position of the egg tray stack from the front, preventing horizontal displacement and ensuring that the egg tray separation and transfer mechanism 30 can accurately separate individual egg trays from the stack. When an egg tray is separated and a new egg tray needs to be added to the separation position, the first longitudinal drive mechanism 2331 activates again, driving the telescopic members 2332 to move backward, releasing the front restraint on the egg tray stack. The conveying device 22 can then transport the new egg tray stack forward a certain distance. The telescopic members 2332 then move toward each other again, restraining the new egg tray stack. This cycle repeats, achieving continuous loading and separation of egg trays.

[0128] In a preferred embodiment of the present invention, the egg tray loading mechanism 20 also includes a rear guard assembly 24, which includes a first transverse drive assembly 241 installed on the first support frame 21 and a support member 242 installed at the output end of the first transverse drive assembly 241. The first transverse drive assembly 241 drives the support member 242 to move horizontally to contact or move away from the back of the egg tray stack.

[0129] Based on the above structure, when the support member 242 contacts the back of the egg tray stack, it can form a stable support in the Z-axis direction, effectively preventing the egg tray stack from tilting backward due to uneven force during the separation process. In particular, when the egg tray separation and transfer mechanism 30 separates a single egg tray from the egg tray stack, it will generate a certain pulling and pushing force on the egg tray stack. At this time, the support member 242 of the rear guard assembly 24 can offset the component of these external forces in the Z-axis direction, ensuring that the egg tray stack always remains stable. When an egg tray is separated and a new egg tray stack needs to be transported to the separation position, the first transverse drive cylinder reverses its action, driving the support member 242 away from the egg tray stack, leaving space for the new egg tray stack to be transported. The above action is then repeated again to achieve continuous and stable support for the egg tray stack.

[0130] In a preferred embodiment of the present invention, the egg tray separation and transfer mechanism 30 includes:

[0131] A mounting plate 31, the mounting plate 31 is installed in the frame 10;

[0132] The linear rotation motion component 32 is mounted on the mounting plate 31;

[0133] Acupuncture assembly 33, which is connected to the linear rotation motion assembly 32;

[0134] The linear-rotational motion assembly 32 is configured to drive the needling assembly 33 to complete three-stage motion:

[0135] Move along the first straight path to the piercing position and pierce the egg tray at the front end of the egg tray stack;

[0136] Retract along the second straight path to the separation position, so that the pierced egg tray is separated from the egg tray stack;

[0137] The egg tray is rotated 90° around the rotation axis 6512 to the release position, and the piercing assembly 33 is released to allow the egg tray to fall.

[0138] In a preferred embodiment of the present invention, the linear-rotational motion assembly 32 includes a rotational drive module 321 and a linear drive module 322. The acupuncture assembly 33 is connected to the linear drive module 322. The linear drive module 322 is used to drive the acupuncture assembly 33 to move along a straight line, and the rotational drive module 321 is used to drive the linear drive module 322 to rotate.

[0139] Specifically, a track limiting groove 311 is formed on the mounting plate 31; the track limiting groove 311 is a three-section continuous path:

[0140] Horizontal section 3111: guides the linear motion of the acupuncture assembly 33;

[0141] Arc segment 3112: transitional rotational motion;

[0142] Vertical section 3113: constrains the vertical lowering path of the egg tray.

[0143] The rotation drive module 321 includes a rotation drive motor 3211, a motion arm 3212 having a strip-shaped slot, and a mounting block 3213 having a limiting shaft. The rotation drive motor 3211 is mounted on the mounting plate 31. One end of the motion arm 3212 is connected to the output shaft of the rotation drive motor 3211. The limiting shaft passes through the strip-shaped slot and is slidably constrained in the track limiting slot 311 of the mounting plate 31.

[0144] The linear drive module 322 includes a rotating seat 3221, a slide rail mounting seat 3222 with a slide groove, and a slide rail 3223 that slides into the slide groove. The rotating seat 3221 is rotatably mounted on the mounting plate 31, and the slide rail mounting seat 3222 is mounted on the rotating seat 3221; one end of the slide rail 3223 is connected to the mounting block 3213, and one end thereof is used to connect the acupuncture assembly 33.

[0145] In a preferred embodiment of the present invention, the acupuncture assembly 33 comprises:

[0146] I-shaped connecting plate 331, the I-shaped connecting plate 331 is installed at one end of the slide rail 3223;

[0147] Four sets of clamping assemblies 332 are symmetrically installed on both sides of the I-shaped connecting plate 331;

[0148] Each clamping assembly 332 includes a clamping plate 3321 , a plurality of puncture needles 3322 and a clamping drive mechanism 3323 .

[0149] A plurality of puncture needles 3322 are arranged at intervals on the inner side of the clamping plate 3321; the clamping drive mechanism 3323 is installed on the I-shaped connecting plate 331, and the clamping drive mechanism 3323 is used to drive the clamping plate 3321 to move radially to achieve the puncture needles 3322 piercing into or out of the egg tray.

[0150] Based on the above structure, the egg tray separation and transfer mechanism 30 adopts a three-order motion control process:

[0151] Stage 1: Needle insertion (penetrating the egg tray)

[0152] In the initial state, the puncture assembly 33 is located behind the egg tray stack (away from the separation position), and the linear rotation motion assembly 32 drives the slide rail 3223 to move forward along the horizontal section 3111 of the track limit groove 311 until the puncture needle 3322 of the puncture assembly 33 is located on both sides of the frontmost egg tray in the egg tray stack; the clamping drive mechanism 3323 is started, the two clamping plates 3321 expand outward, and the puncture needle 3322 pierces the side of the egg tray (the puncture depth is controlled by the stroke of the clamping drive mechanism 3323); at this time, the puncture assembly 33 forms a reliable connection with the frontmost egg tray in the egg tray stack, preparing for the separation action.

[0153] 2. Second stage: separation (piercing the egg tray and separating it from the pile)

[0154] After the needle is inserted, the linear rotation motion component 32 drives the slide rail 3223 to retreat along the horizontal section 3111 of the track limit groove 311, driving the linear drive module 322 to move as a whole in the direction away from the egg tray stack; because the puncture needle 3322 has penetrated the egg tray, during the withdrawal process, the friction between the front end egg tray of the egg tray stack and the rear stack body is cut off by the puncture needle 3322, thereby realizing the separation of the single egg tray from the stack body; during the separation process, the support member 242 of the rear guard component 24 continues to press against the back of the egg tray stack to prevent the stack body from tilting backward due to the separation pulling force.

[0155] 3. The third stage: release (the egg tray falls to the conveyor mechanism)

[0156] After the separation is completed, the linear rotation motion component 32 drives the slide rail 3223 to rotate 90° along the track limit groove 311 to the vertical direction, and moves the acupuncture component 33 to the top of the conveying waiting mechanism; the linear rotation motion component 32 continues to drive the slide rail 3223 to move downward along the vertical section 3113 of the track limit groove 311, the clamping drive mechanism 3323 contracts, and the puncture needle 3322 exits the egg tray. After losing support, the egg tray freely falls onto the conveyor belt of the conveying waiting mechanism; then, the linear rotation motion component 32 is reset (the slide rail 3223 moves upward along the vertical section 3113, the rotation drive module 321 drives the motion arm 3212 to rotate back to the initial angle, and the slide rail 3223 withdraws to the initial position along the horizontal section 3111), completing a complete separation cycle.

[0157] In this way, the coordination of the trajectory limiting groove 311 and the linear-rotational motion assembly 32 achieves path constraint for third-order motion, avoiding the trajectory deviation of traditional linear motion mechanisms and ensuring that the puncture needle 3322 accurately penetrates the designated location on the egg tray. The modular, symmetrical design of the puncture assembly 33 achieves efficient and low-loss separation of the egg tray from the stack, resolving the issues of easy damage and low efficiency associated with traditional egg tray separation. Furthermore, the design of the I-shaped connecting plate 331 prevents interference with the blocking assembly 233 during needle insertion.

[0158] In a preferred embodiment of the present invention, the egg tray transmission waiting mechanism 40 includes:

[0159] The egg tray conveying assembly 41 includes a second support frame 411 and a belt conveying mechanism 412 mounted on the second support frame 411;

[0160] Three first photoelectric sensor components 42 are arranged on the second support frame 411 at intervals in the transmission direction;

[0161] A mechanical limit plate 43 is provided on the second support frame 411 and is located at the end of the transmission;

[0162] Among them, the first photoelectric sensor component 42 at the front end of the transmission sends a sensor signal to start the transmission, the first photoelectric sensor component 42 at the end of the transmission sends a sensor signal to terminate the transmission, and the first photoelectric sensor components 42 at the middle and end of the transmission respectively send sensor signals to jointly trigger the double egg tray ready instruction.

[0163] Based on the above structure, through the rational layout and functional coordination of the three first photoelectric sensor components 42, the egg tray conveying process is automatically and precisely controlled, eliminating the need for manual intervention in the start and stop of egg tray conveying, thereby improving conveying efficiency and accuracy. The provision of the mechanical limit plate 43 further ensures the stability of the egg tray while waiting to be boxed, preventing damage or confusion caused by egg trays falling. The triggering mechanism of the double egg tray ready instruction can promptly feedback the egg tray preparation status to the central control system, enabling the egg tray grabbing and boxing mechanism 50 and the egg tray conveying waiting mechanism 40 to achieve efficient coordination, optimizing the entire egg tray separation and boxing process, reducing the equipment's idling waiting time, and significantly improving the equipment's overall operating efficiency.

[0164] In a preferred embodiment of the present invention, the egg tray grabbing and boxing mechanism 50 includes two square tube frames mounted on the frame 10 and a synchronous belt horizontal conveying mechanism 51 mounted on the two square tube frames;

[0165] The transport installation plate 52 is installed on the synchronous belt;

[0166] A vertical drive assembly 53 is mounted on the transport mounting plate 52;

[0169] Specifically, the grabbing assembly 54 includes a grabbing base plate 541 mounted on the output shaft of the lifting cylinder, and a clamping assembly 542; the clamping assembly 542 includes a clamping drive mechanism 5421 mounted on the grabbing base plate 541 and a clamping plate 5422 mounted on the output shaft of the clamping drive mechanism 5421; the clamping drive mechanism 5421 is used to drive the clamping plate 5422 to move radially to clamp or release the egg tray.

[0170] Building on the aforementioned structure, the egg tray grabbing and packing mechanism 50 utilizes a combination of a square tube frame, a synchronous belt horizontal conveyor mechanism 51, a vertical drive assembly 53, and a grab assembly 54. This design features a simple, compact structure and stable, reliable operation. The vertical drive assembly 53's lifting and lowering cylinder responds quickly, accurately controlling the vertical position of the grab assembly 54 to ensure accurate egg tray grabbing and placement. The gripping drive mechanism 5421 and gripping plate 5422 of the gripping assembly 542 ensure stable gripping of egg trays of varying sizes, preventing them from falling or becoming damaged during the grabbing and handling process. This overall design automates and precisely controls the egg tray grabbing and packing process, significantly improving packing efficiency and quality while reducing manual intervention, labor intensity, and labor costs. It also enhances the equipment's adaptability to diverse production scenarios.

[0171] In a preferred embodiment of the present invention, the carton identification and blocking mechanism comprises:

[0172] The third support frame 61 is installed in the frame 10 and is located between the carton feed port 12 and the carton discharge port 13;

[0173] Roller conveying assembly 62, the roller conveying assembly 62 is installed on the third support frame 61;

[0175] The interception mechanism 64 is mounted on the third support frame 61 and includes a first baffle 641 that can be raised or lowered and a lifting drive assembly 642. The lifting drive assembly 642 is used to drive the first baffle 641 to rotate upward or downward to switch the first baffle 641 between a blocking state and an unblocking state. The first baffle 641 extends upward from the gap between adjacent rollers in the blocking state and retracts downward to below the roller surface in the unblocking state.

[0176] The box supporting assembly includes two sets of box supporting mechanisms 651, which are symmetrically installed on both sides of the third support frame 61. The flipping parts 6513 of the two sets of box supporting mechanisms 651 are synchronously flipped into the top opening of the carton to open the top opening of the carton.

[0177] In a preferred embodiment of the present invention, the box supporting mechanism 651 includes a door-shaped mounting frame 6511, a rotating shaft 6512, two flip members 6513, and a rotating drive assembly 6514;

[0178] The door-shaped mounting frame 6511 is installed on one side of the third supporting frame 61;

[0179] The rotating shaft 6512 is rotatably mounted on the upper portion of the door-shaped mounting frame 6511;

The flip members 6513 include a fixed portion fixedly connected to the rotating shaft 6512, a vertical abutting portion extending along one side of the fixed portion, and a longitudinal abutting portion along one side of the vertical abutting portion.

[0181] The rotary drive assembly 6514 drives the rotating shaft 6512 to rotate, driving the four flipping members 6513 to flip synchronously into the top opening of the carton and press against the four corners.

[0182] On the basis of the above structure, the design of the carton identification, blocking and supporting mechanism realizes the automatic identification of the carton in place through the second photoelectric sensor component 63, providing an accurate signal basis for the subsequent blocking and supporting operations. The design of the liftable first baffle 641 of the interception mechanism 64 can flexibly block and release the carton, ensuring that the carton stays at the predetermined position for packing operations. The two sets of supporting mechanisms 651 of the supporting assembly are symmetrically arranged, and the unique structure of its flip part 6513 can accurately support the four corners of the top opening of the carton, so that the carton opening remains in a stable open state, facilitating the smooth placement of egg trays into the carton, and effectively avoiding problems such as damage to the egg tray or displacement of the packing position caused by collision between the egg tray and the edge of the carton during the packing process. The coordinated work of this mechanism realizes the fully automated process of carton conveying, identification, blocking and supporting, improves the efficiency and accuracy of carton processing, further optimizes the workflow of the entire egg tray separation and packing equipment, and improves the overall performance and reliability of the equipment.
