Description

Technical Field

[0001] This invention belongs to the technical field of canned food conveying equipment, and relates to a canned food conveying device, particularly a novel finished product conveying device for processing bird's nest canned goods. Background Technology

[0002] Bird's nest is rich in sugars, organic acids, free amino acids, and the characteristic substance sialic acid. It is a traditional nutritional supplement, typically packaged in cans. Bird's nest is a high-value, fragile product: canned bird's nest is mostly in glass / ceramic containers, and due to the high value of its contents, traditional transportation methods result in a high breakage rate from collisions, necessitating a zero-contact cushioning design. Packaging complexity: multiple layers of protective panels (partitions) are required to separate the cans and prevent collisions during transport; traditional manual insertion of these panels is inefficient. Strict quality control: the liquid state of bird's nest easily separates, requiring continuous visual inspection; traditional sampling inspections have a high rate of missed detections.

[0003] Therefore, stable transportation is required in the packaging of bird's nests. General equipment cannot meet the requirements of non-destructive sorting, precise stacking of protective plates, and high-speed quality inspection. Breakthroughs in zero-damage transportation and fully automated collaboration are urgently needed.

[0004] Based on this, we propose a novel finished product conveying device for processing bird's nest canned goods. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a novel finished product conveying device for processing canned bird's nest. The technical problem this invention aims to solve is: how to achieve efficient and stable sequential sorting, diversion, positioning, alternating stacking with protective plates, full-layer stacking into boxes, and full-box output of canned bird's nest.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A novel finished product conveying device for processing canned bird's nest includes a conveying frame and a box frame assembly located at the rear of the conveying frame. The conveying frame is equipped with a parallel-arranged guiding conveyor, a double-position conveyor, and a retraction conveyor. The retraction conveyor is located at the front left side of the guiding conveyor, and the double-position conveyor is located at the rear left side of the guiding conveyor. The retraction conveyor and the guiding conveyor have opposite conveying directions, while the double-position conveyor and the guiding conveyor have the same conveying direction. From front to back, the conveying frame is equipped with a diversion mechanism, a guiding mechanism, a material blocking and braking mechanism, a can transfer mechanism, and a guard plate transfer mechanism. The material blocking braking mechanism, can transfer mechanism, and guard plate transfer mechanism are all located directly above the material guiding conveyor. A material stopping braking mechanism is located on the right rear of the conveyor frame, between the can transfer mechanism and the guard plate transfer mechanism. A guard plate unloading mechanism is located on the left rear of the conveyor frame, on the left side of the double-position conveyor. The end of the double-position conveyor extends into the box frame assembly. The box frame assembly contains a box packing and handling mechanism and a box conveyor line. The box conveyor line runs through the box frame assembly and is located behind the double-position conveyor. The box packing and handling mechanism is located above the box conveyor line.

[0008] The working principle of this invention: Processed bird's nest cans first enter the feeding conveyor and are transported from front to back. During transport, a diversion mechanism inspects the cans; defective or reworkable products are pushed onto a return conveyor and returned in the opposite direction. Qualified products continue to be transported along the feeding conveyor and sequentially transported to the guiding mechanism by the diversion mechanism. The guiding mechanism ensures they enter subsequent stations with the correct spacing and direction. A stopping brake mechanism precisely stops and positions the cans before they reach critical stations. A stopping brake mechanism is located near the rear can transfer area and is used to pause the can transport when necessary. A protective plate release mechanism is located on the left side of the double-position conveyor and is responsible for storing and orderly releasing protective plates used to protect the cans or separator layers. A protective plate transfer mechanism places one protective plate released by the protective plate release mechanism at a designated position at the front end of the double-position conveyor. Can transfer: The can transfer mechanism precisely positions... Good cans are picked up from the feeder conveyor and transferred to the guard plate located at the front end of the double-position conveyor. The guard plate transfer mechanism places a guard plate released by the guard plate dispensing mechanism onto the positioned can, meaning that the top and bottom surfaces of the positioned can are both covered with guard plates. The above operation is repeated, and according to the set pattern, can be stacked with one layer of cans and one layer of guard plates, or one layer of cans and multiple layers of guard plates, with the last layer of cans also having one more guard plate. The double-position conveyor transports the cans and the guard plates placed on both the top and bottom surfaces to the box rack assembly. The box conveyor line runs through the box rack assembly and is responsible for transporting empty packaging boxes from the storage area to the position directly opposite the double-position conveyor. The box packing and handling mechanism sequentially transfers the cans and the guard plates placed on both the top and bottom surfaces above the double-position conveyor, and the cans and guard plates are stacked inside the empty packaging boxes according to the set pattern. After packing is completed, the packaging boxes are sent out of the box rack assembly via the box conveyor line to enter the next stage.

[0009] The flow guiding mechanism includes several crossbeams distributed in a front-to-back direction. The crossbeams are fixed above the conveying frame. An adjustable locking block is provided on the foremost crossbeam, and several equally spaced adjustable locking blocks are provided on the remaining crossbeams. Side baffles are provided on the adjustable locking blocks on the foremost crossbeam and the sidemost adjustable locking blocks on the remaining crossbeams. Flow guide plates are provided on the corresponding adjustable locking blocks on the remaining crossbeams. The side baffles and several flow guide plates are arranged in parallel, and flow guiding channels are formed between the side baffles and adjacent flow guide plates, as well as between two adjacent flow guide plates. A baffle shaft and a baffle motor are provided on the two middle crossbeams. The output shaft of the baffle motor and the baffle shaft are connected by a transmission. Several baffle blocks are fixed on the baffle shaft, and the baffle blocks correspond to the positions of the flow guiding channels.

[0010] Using the above structure, the distance between the side baffles and the guide plates, as well as the distance between two adjacent guide plates, can be adjusted according to the size of the bird's nest cans. The bird's nest cans are stably conveyed backward from the feeding conveyor. The cans first contact the outermost side baffle and enter the diversion mechanism. After being diverted by the diversion mechanism, as the cans continue to move backward on the conveyor belt, they are forcibly guided into parallel guide channels formed by the side baffles and multiple guide plates. Each channel typically only accommodates a single row of cans arranged front to back, continuously constraining the cans and preventing them from shifting left or right or rotating. Dynamic blocking control stage: The can queue advances within the guide channels to below the crossbeam frame area equipped with blocking shafts and blocking blocks. Initial / blocking state: In the default or controlled state, the blocking blocks are in the falling position, their ends extending into the corresponding guide channel, blocking the foremost can in that channel. Accumulated queue: Blocked. When the canned goods stop moving, the canned goods in the same channel continue to be conveyed forward, naturally accumulating behind the baffle blocks to form a waiting queue; the queues in different channels are independent; controlled release: when the control system issues a command: the baffle motor starts, driving the baffle shaft to rotate, and all the baffle blocks fixed on the shaft rotate synchronously to the raised position, retracting from the guide channel; cans move forward: the obstruction is released, and the blocked cans, driven by the conveyor belt, smoothly pass through the previously blocked position and continue to flow to the subsequent workstation; obstruction is restored: after a preset time, the baffle motor starts again, driving the baffle blocks to rotate back to the blocking position, re-extending into the guide channel, blocking the new first can in the queue of that channel, waiting for the next release signal; cycle: the above lifting-lowering action is performed cyclically according to the system rhythm and downstream demand, precisely controlling the flow rate and rhythm of cans passing through each guide channel.

[0011] The diversion mechanism includes a mounting frame one, two symmetrically arranged material-feeding electric screw components, and two symmetrically arranged mounting frames two. Mounting frame one and the two mounting frames two are fixed above the conveyor frame. Mounting frame one is located in front of the foremost crossbeam, and the two mounting frames two are located between the two foremost crossbeams. Mounting frame one is fixed with several high-frequency cameras facing the material conveyor. The two material-feeding electric screw components are respectively arranged on the front and rear sides of the foremost crossbeam. Material-feeding plate frames are fixed on the sliding seats of the two material-feeding electric screw components, facing the retraction conveyor. The lower end of the front mounting frame two is adjustablely provided with two symmetrically arranged guide plates, which are flared in shape. Diversion plates are hinged to the ends of the two guide plates. Diversion motors are fixed to the upper ends of the two mounting frames two, and diversion drive rods are fixed to the lower ends of the diversion motors. The ends of the diversion drive rods are hinged to the upper ends of the two diversion plates, forming a diversion channel between the two guide plates and the two diversion plates.

[0012] Using the above structure, the distance between the two guide plates and the distance between the two diverting plates can be adjusted according to the size of the bird's nest cans. Driven by the material conveyor, the cans pass under the area of ​​the high-frequency cameras fixed on the mounting frame. Multiple high-frequency cameras capture images of each can quickly and continuously from a preset angle. The images are transmitted to the control system for real-time analysis and processing. The control system determines whether the current can is qualified based on the image analysis algorithm. If the can is unqualified, the control system issues a command, and the sliding seat of the feeding electric screw drives the feeding plate frame to push the can onto the retraction conveyor, and outputs the retraction in the opposite direction. If the can is qualified, the control system issues a command, and the diverting mechanism guides the can to continue to be conveyed backward along the material conveyor. It first contacts the trumpet-shaped guide plate. The trumpet design naturally converges and centrally arranges the cans, which then enter the interior of the two diverting plates. The diverting motor drives the diverting drive rod to rotate to a specific angle, so that the two diverting plates are in the "straight" position. At this time, the diverting plates successively cooperate with the inlet of the guiding channel, and the cans flow into the corresponding guiding channel of the guiding mechanism, and are conveyed backward evenly.

[0013] The material stopping braking mechanism includes a side fixing plate, which is fixed to the rear right side of the conveying frame. An adjusting seat is adjustable on the side fixing plate, and a material equalization braking push rod is fixed on the adjusting seat. A moving plate is slidably provided on the adjusting seat. The telescopic end of the material equalization braking push rod is fixedly connected to the moving plate. A braking crossbeam is fixed on the moving plate. The braking crossbeam is located at the upper end of the material guiding conveyor. Several equally spaced braking plates are adjustable on the braking crossbeam. The position and number of the braking plates correspond to those of the guiding channel.

[0014] Using the above structure, the position of the adjusting seat on the side plate is adjusted, allowing the overall adjustment of the position of each braking actuator relative to the canned food flow on the material conveyor, ensuring that the braking action occurs at a precise preset work point; the equal material braking push rod drives the moving plate to slide back and forth on the adjusting seat, driving the braking crossbeam and all braking plates to slide back and forth, used to adjust the position of the braking plates to adapt to the placement and positioning of bird's nest cans of different sizes; driven by the material conveyor, the cans pass through the area unimpeded in their respective guide channels, flowing to the subsequent transfer work station, and the cans are stably stopped at the can transfer mechanism.

[0015] The material blocking braking mechanism includes a brake frame, which is fixed above the conveying frame. Two drive screws are rotatably mounted on the brake frame, and a pulley pair is provided between the two drive screws. An adjustment handwheel is fixed to the upper end of one of the drive screws. A lifting plate is slidably mounted on the inner side of the brake frame. The lifting plate is screwed and driven by the two drive screws. A vertically mounted material blocking brake push rod is fixed on the lifting plate. A brake cross plate is fixed to the telescopic end of the material blocking brake push rod. Several equally spaced brake pins are detachably mounted on the brake cross plate. The position and number of the brake pins correspond to the guide channel.

[0016] Using the above structure, the initial height adjustment involves the operator rotating the adjustment handwheel, which drives the connected drive screw to rotate. The two drive screws rotate synchronously via pulley pairs, driving the lifting plate to rise and fall vertically along the brake frame. The entire brake actuator assembly fixed to the lifting plate rises and falls synchronously. The end of the brake column is adjusted to be slightly higher than the top of the target can. After adjustment, the screw's self-locking characteristic or an additional locking device will maintain the position. Normal operation / brake release: The stop brake push rod is in the retracted state; the entire brake column assembly is in a high position; the end of the brake column is higher than the lower guide channel; the cans, driven by the conveyor, pass unobstructed through their respective guide channels. Trigger braking / precise positioning: When the control system determines that the can needs to be precisely positioned below the stop brake mechanism, it issues an extension command to the stop brake push rod; the telescopic end of the stop brake push rod quickly extends downwards, and the thrust is transmitted through the telescopic end to the fixed... A fixed brake plate moves all brake pins downwards synchronously, with the ends of the pins precisely inserted into their respective guide channels. Cans moving forward in the guide channels are directly blocked by the ends of the brake pins and immediately stop on the conveyor belt. The cans are fixed in a precise preset position, determined by the end of the push rod's stroke and the previously manually adjusted height. Cans in the same channel continue to be conveyed forward, accumulating naturally behind the brake pins. At this time, the cans are in a precisely positioned state, awaiting subsequent actions. When the subsequent actions are completed, the control system sends a retraction command to the stop brake push rod. The telescopic end of the stop brake push rod quickly retracts upwards. The pulling force pulls the brake plate through the telescopic end, causing all brake pins to move upwards synchronously. The ends of the brake pins completely exit the guide channel, clearing the path. With the obstruction released, the blocked and positioned cans immediately resume movement under the drive of the conveyor belt, flowing to the next station. The queue of accumulated cans also moves forward in sequence.

[0017] The canned food transfer mechanism includes a horizontal electric lead screw component, which is fixed on the conveying frame. A vertical electric lead screw component is provided on the sliding seat of the horizontal electric lead screw component. A transfer frame is detachably provided on the sliding seat of the vertical electric lead screw component. Several sets of evenly distributed transfer suction cups are provided on the transfer frame, and the transfer suction cups are connected to an external vacuum pump.

[0018] Using the above structure, the horizontal electric screw first moves the vertical electric screw first and the transfer frame first to directly above the guide conveyor, corresponding to the position of the guide channel; the vertical electric screw first raises the transfer frame first to a high position, and the transfer suction cups first move away from the cans; the control system confirms that the cans in the guide channel have been accurately positioned at the gripping point under the action of the material blocking braking mechanism or similar mechanism; the vertical electric screw first drives its sliding seat to descend rapidly, driving the transfer frame first and several sets of evenly distributed transfer suction cups first to move downward, and the several sets of evenly distributed transfer suction cups first contact the top surface of the cans; the vacuum solenoid valve opens, the vacuum pump works, and negative pressure is generated inside the transfer suction cups first, firmly adsorbing the target cans, and several cans corresponding to each guide channel are grabbed by a set of suction cups above them; the vertical electric screw first drives the sliding seat to rise rapidly. The transfer rack holding the can is raised to a safe height, completely removing the can from the surface and flow channel of the material conveyor. The horizontal electric screw drives its sliding seat to move precisely, horizontally moving the entire vertical gripping component holding the can to the designated packing position above the double-position conveyor. The vertical electric screw then drives the sliding seat to descend precisely, placing the can at the designated point on the double-position conveyor, while the transfer suction cup remains attached. Upon reaching the predetermined release height, the vacuum solenoid valve closes, releasing the negative pressure, separating the transfer suction cup from the top surface of the can, and the can is precisely released. The vertical electric screw then raises the unloaded transfer rack to a high position. The horizontal electric screw then drives the entire mechanism to move horizontally back to the initial gripping position above the material conveyor, awaiting the next work cycle.

[0019] The guard plate transfer mechanism includes a second horizontal electric lead screw component, which is fixed on the conveying frame. A second vertical electric lead screw component is provided on the sliding seat of the second horizontal electric lead screw component. An adjusting frame is fixed on the sliding seat of the second vertical electric lead screw component. A second transfer frame is detachably provided on the adjusting frame. A row of evenly distributed transfer suction cups is provided on the second transfer frame. The second transfer suction cups are connected to an external vacuum pump.

[0020] Using the above structure, the second horizontal electric lead screw moves the second vertical electric lead screw, the adjusting frame, and the second transfer frame to a position directly above the guard plate feeding mechanism, ready for gripping. The second vertical electric lead screw raises the entire gripping head to a high position, the vacuum system is closed, and the control system confirms that the guard plate feeding mechanism has prepared a guard plate to be gripped. The second vertical electric lead screw drives its sliding seat to descend precisely and smoothly, and the second transfer suction cup evenly contacts the upper surface of the guard plate. The vacuum is activated, and negative pressure is generated inside the second transfer suction cup, flattening and adsorbing the guard plate. The second vertical electric lead screw continues to raise the gripping head to a safe height, causing the guard plate to leave the feeding area. The second horizontal electric lead screw... The sliding seat is precisely moved, horizontally shifting the entire mechanism holding the protective plate to the target placement position above the double-position conveyor. The second vertical electric screw drives the sliding seat to descend precisely and slowly, smoothly approaching the protective plate to the target placement surface. When the protective plate is about to touch or slightly touches the placement surface, the vacuum is closed, releasing the suction force. The protective plate lands on the target position. The second vertical electric screw immediately drives the sliding seat to rise, causing the suction cup to detach from the protective plate. The second vertical electric screw raises the unloaded gripping head to a high position. The second horizontal electric screw drives the entire mechanism to move horizontally back to the initial gripping position above the protective plate unloading mechanism, awaiting the next gripping command.

[0021] The guard plate feeding mechanism includes a plate collection frame, a rotating shaft, and a feeding motor. The plate collection frame is adjustablely hinged to the rear left side of the conveying frame. A baffle is hinged to the plate collection frame. The rotating shaft is rotatably mounted on the conveying frame. A second moving rod and two feeding frames are adjustablely mounted on the rotating shaft. Several feeding suction cups are provided at the upper end of each feeding frame. The feeding motor is fixed on the conveying frame. A first moving rod is fixed on the output shaft of the feeding motor. A drive connecting rod is hinged between the first moving rod and the second moving rod.

[0022] Using the above structure, the feeding motor drives the first moving rod to rotate to a specific angle, which pushes / pulls the second moving rod through the drive linkage. The second moving rod drives the rotating shaft to rotate to the material picking angle. The two feeding racks fixed on the rotating shaft and their feeding suction cups are positioned directly above the top layer of the tray. The suction cups are vertically downward or slightly tilted, aligned with the tray. The vacuum system is closed, and the material is lowered and picked up. The feeding suction cups contact the surface of the top layer of the tray, the vacuum is activated, and the feeding suction cups adhere to the top layer of the tray. The output shaft of the feeding motor drives the first moving rod to rotate continuously. The rotation of the first moving rod is converted into the reciprocating rocking motion of the second moving rod through the drive linkage. The rocking motion of the second moving rod drives the rotating shaft to rotate, and the two feeding racks fixed on the rotating shaft feed the material. The suction cup and the protective plate it adsorbs rotate synchronously; the protective plate is flipped from a near-vertical / tilted storage posture above the collection rack to a near-horizontal release posture; when the feeding rack rotates to the predetermined feeding angle, the vacuum is closed, and the protective plate smoothly detaches from the feeding suction cup under the action of gravity and falls to the predetermined waiting position below. This position is the gripping starting point of the protective plate transfer mechanism. The transfer suction cup two of the protective plate transfer mechanism then descends to grip the released protective plate; the feeding motor continues to rotate, driving the first moving rod to return to the initial angle, and through the drive linkage, driving the second moving rod to rock in the opposite direction, the rotating shaft rotates in the opposite direction, driving the unloaded feeding rack and feeding suction cup to flip back to the picking position above the collection rack, ready for the next picking cycle.

[0023] The box rack assembly includes a box rack body, with box-blocking electric push rods on both the left and right sides inside the box rack body. A fixed box rack is fixed between the lower ends of the box-blocking electric push rods. Several packaging boxes are placed above the box conveyor line. A main control computer is located on the side of the box rack body.

[0024] Using the above structure, several empty packaging boxes are placed above the box conveyor line. They are sequentially conveyed by the box conveyor line to the position directly opposite the double-position conveyor inside the box frame assembly. The electric push rod of the box stop drives the fixed box frame to descend, and the fixed box frame presses against the empty packaging box that is ready to be filled with canned goods, ensuring the stability of the empty packaging box and facilitating the filling of the canned goods. After the filling is completed, the electric push rod of the box stop drives the fixed box frame to rise, and the fixed box frame releases the pressing against the packaging box. The box conveyor line then sequentially conveys the packaging boxes out of the box frame assembly and to the downstream workstation. The main control computer is a human-machine interface of an industrial control computer or a programmable logic controller, which sets or adjusts the operating parameters of relevant equipment and acts as a local control unit or monitoring terminal.

[0025] The frame assembly includes a fixed plate, which is fixed to the top front side inside the frame body. A synchronizing rod and two connecting arms are hinged to the side of the fixed plate. Connecting arms are hinged to the ends of both connecting arms. Synchronizing triangular plates are hinged to the hinge shafts of connecting arms one and two. A fixed frame is hinged to the ends of the two connecting arms two, and a synchronizing rod is hinged to the fixed frame. Synchronizing rod two and synchronizing rod one are respectively hinged to the ends of the synchronizing triangular plates. A transport motor two is fixed to the fixed plate. The output shaft of the transport motor two is connected to the hinge shafts of the fixed plate and the connecting arms one. A transport motor one is fixed to one of the connecting arms two, and its output shaft is connected to the hinge shafts of connecting arms one and two. An adjusting electric screw is located at the lower end of the fixed frame. Several suction cup frames are fixed to the sliding seat of the adjusting electric screw. The suction cup frames are slidably mounted on the adjusting electric screw. Several evenly distributed transfer suction cups are located at the lower end of the suction cup frames, and the transfer suction cups are connected to an external vacuum pump.

[0026] Using the above structure, the second and first transport motors position the mechanism at a safe high position, typically near the upper side of the main frame. Adjusting the electric lead screw positions the suction cup holder to the default or previous task width position. The vacuum system is shut off, and the control system receives a signal that the can layers on the double-position conveyor are arranged and the empty packaging boxes inside the main frame are ready. The second transport motor drives the first connecting arm to rotate, causing the entire mechanism to swing downwards and forwards, moving it directly above the arranged layers on the double-position conveyor. The first transport motor drives the second connecting arm to rotate, performing fine-tuning of position and attitude, ensuring that several sets of transfer suction cups are precisely aligned with the can layers or protective plates. The coordinated action of the second and first transport motors causes the transfer suction cups to contact the top surface of the arranged can layers or the uppermost protective plate. The vacuum is activated, and all the material suction cups adsorb the entire layer of material. The second transport motor drives the first connecting arm to rotate in the opposite direction, while the first transport motor coordinates with the second connecting arm to lift the portion adsorbing the entire layer of material to a high position and swing it backward and upward, moving it towards the empty packaging box inside the main frame. Synchronous rods two and one work together to ensure the fixed frame remains horizontal during the transfer. The coordinated action of the second and first transport motors drives the end of the mechanism to descend smoothly, placing the material layer into the empty packaging box. Once the predetermined depth is reached, the vacuum is closed, releasing the entire layer of material. The second and first transport motors then work together to lift and swing the empty portion back to its initial high, ready position, awaiting the next cycle.

[0027] Compared with existing technologies, this novel finished product conveying device for processing bird's nest canned goods has the following advantages:

[0028] The continuous conveying of canned bird's nest is achieved through a guiding conveyor. A diversion mechanism, a guiding mechanism, a material blocking braking mechanism, and a stopping braking mechanism precisely control the path and position of the cans. A protective plate transfer mechanism works in conjunction with a protective plate unloading mechanism to stably transfer and place the protective plates. The can transfer mechanism and the protective plate transfer mechanism, working in tandem with a dual-position conveyor, complete the combination and arrangement of cans and protective plates. The combination method can be selected flexibly to avoid collision damage to the canned bird's nest after packaging, effectively protecting the canned bird's nest and reducing losses. The box rack assembly and box conveyor line transport empty boxes, while the boxing and handling mechanism performs the crucial gripping and packing actions. The diversion mechanism, in conjunction with a retraction conveyor, screens and reverses the transport of defective products, ensuring the quality of the canned bird's nest and reducing losses. The entire system is compact in design, highly automated, and with all components working collaboratively, it achieves a highly efficient and automated conveying process for canned bird's nest from finished product output to complete packaging.

[0045] The processed bird's nest cans first enter the feeding conveyor 2 and are transported from front to back. During the transport process, the diversion mechanism 3 inspects the bird's nest cans. Defective or reworkable products are pushed onto the return conveyor 14 and returned in the opposite direction. Qualified products continue to be transported along the feeding conveyor 2 and are sequentially transported by the diversion mechanism 3 to the guiding mechanism 4. The guiding mechanism 4 ensures that they enter the subsequent workstations with the correct spacing and direction. The material blocking and braking mechanism 5 precisely stops the cans before they reach the critical workstations (such as transfer points). And positioning; the stopping brake mechanism 13 is located near the rear can transfer area (between the can transfer mechanism 6 and the guard plate transfer mechanism 7), used to pause the can conveying when needed (such as waiting for transfer or packing); the guard plate dispensing mechanism 12 is located on the left side of the double-position conveyor 11, responsible for storing and orderly releasing guard plates (cardboard, foam board, etc.) used to protect cans or separator layers; the guard plate transfer mechanism 7 places one guard plate released by the guard plate dispensing mechanism 12 at a designated position at the front end of the double-position conveyor 11; can transfer: can transfer The conveying mechanism 6 picks up the precisely positioned cans from the guide conveyor 2 and transfers them to the protective plate located at the front end of the double-position conveyor 11; the protective plate transfer mechanism 7 places a protective plate released by the protective plate dispensing mechanism 12 onto the positioned can, that is, both the upper and lower ends of the positioned can are covered with protective plates; repeating the above operation, according to the set method, can form a stack of one layer of cans and one layer of protective plates or one layer of cans and multiple layers of protective plates, with the last layer of cans also having one layer of protective plates; the double-position conveyor 11 places the cans and their upper and lower ends onto the protective plates. The protective plates are conveyed to the box rack assembly 8; the box conveyor line 10 runs through the box rack assembly 8 and is responsible for conveying the empty packaging box 60 from the storage area to the position directly opposite the double-position conveyor 11; the box packing and handling mechanism 9 sequentially transfers the cans above the double-position conveyor 11 and the protective plates placed on both the upper and lower ends, and the cans and protective plates are stacked and placed inside the empty packaging box 60 according to the set method; after the box is packed, the packaging box 60 is sent out of the box rack assembly 8 through the box conveyor line 10 and enters the next stage (such as sealing, labeling, and palletizing).

[0046] The flow guiding mechanism 4 includes several crossbeams 15 distributed in the front-back direction. The crossbeams 15 are fixed above the conveying frame 1. An adjusting locking block 16 is adjustable on the frontmost crossbeam 15. Several equally spaced adjusting locking blocks 16 are adjustable on the remaining crossbeams 15. Side baffles 17 are provided on the adjusting locking blocks 16 on the frontmost crossbeam 15 and the sidemost adjusting locking blocks 16 on the remaining crossbeams 15. Flow guiding plates 18 are provided on the corresponding adjusting locking blocks 16 on the remaining crossbeams 15. The side baffles 17 and several flow guiding plates 18 are arranged in parallel. Flow guiding channels are formed between the side baffles 17 and adjacent flow guiding plates 18, as well as between two adjacent flow guiding plates 18. The two crossbeams 15 in the middle are provided with a baffle shaft and a baffle motor. The output shaft of the baffle motor and the baffle shaft are connected by a transmission. Several baffle blocks 19 are fixed on the baffle shaft. The baffle blocks 19 are positioned corresponding to the flow guiding channels.

[0047] The distance between the side baffle 17 and the guide plate 18, as well as the distance between two adjacent guide plates 18, can be adjusted according to the size of the bird's nest cans. The bird's nest cans are stably conveyed backward from the feeding conveyor 2. The bird's nest cans first come into contact with the outermost side baffle 17 and enter the diversion mechanism 3. After being diverted by the diversion mechanism 3, as the cans continue to move backward on the conveyor belt, they are forced into the parallel guide channels formed by the side baffle 17 and multiple guide plates 18. Each channel can usually only accommodate the front of a single row of cans. The can queue is then arranged in a continuous manner to constrain the cans and prevent them from shifting left or right or rotating. During the dynamic blocking control phase, the can queue advances within the guide channel to the area below the crossbeam frame 15, which is equipped with blocking shafts and blocking blocks 19. In the initial / blocking state, under default or controlled conditions, the blocking block 19 is in a falling (vertical) position, with its end extending into the corresponding guide channel, blocking the foremost can in that channel. In the cumulative queue, the blocked cans stop, and subsequent cans in the same channel continue to be conveyed forward, naturally queuing behind the blocking block 19. The queues accumulate to form waiting queues; queues in different channels are independent; controlled release: when the control system (based on the preparation signal of downstream processes such as can transfer mechanism 6, cycle requirements, etc.) issues a command: the baffle motor starts, driving the baffle shaft to rotate, and all baffle blocks 19 fixed on the shaft rotate synchronously to the raised (horizontal) position, retracting from the guide channel; cans advance: the obstruction is released, and the blocked cans (usually one or more at the front of each channel queue) are smoothly passed through the original blocked position by the conveyor belt and continue to flow to the subsequent station; the obstruction is restored: after a preset time (or after the sensor signal confirms that the cans have passed), the baffle motor is activated again, driving the baffle block 19 to rotate back to the blocking position, re-extending into the guide channel to block the new frontmost can in the queue of that channel, waiting for the next release signal; cycle: the above-mentioned raising (release) and lowering (blocking) actions are performed cyclically according to the system cycle and downstream demand, precisely controlling the flow rate and rhythm of cans passing through each guide channel.

[0048] The diversion mechanism 3 includes a first mounting frame 20, two symmetrically arranged feeding electric screws 22, and two symmetrically arranged second mounting frames 25. The first mounting frame 20 and the two second mounting frames 25 are all fixed above the conveyor frame 1. The first mounting frame 20 is located in front of the foremost crossbeam 15, and the two second mounting frames 25 are located between the two foremost crossbeams 15. Several high-frequency cameras 21 are fixed on the first mounting frame 20, facing the material conveyor 2. The two feeding electric screws 22 are respectively arranged on the front and rear sides of the foremost crossbeam 15. Each of the sliding seats of the electric lead screw component 22 is fixed with a material feeding plate frame 23, which is directly opposite the retraction conveyor 14. The lower end of the front mounting bracket 25 is adjustablely provided with two guide plates 24 arranged symmetrically on the left and right. The two guide plates 24 are flared, and the ends of the two guide plates 24 are hinged with diverter plates 28. The upper end of the two mounting brackets 25 is fixed with a diverter motor 26, and the lower end of the diverter motor 26 is fixed with a diverter drive rod 27. The end of the diverter drive rod 27 is hinged to the upper end of the two diverter plates 28, and a diverter channel is formed between the two guide plates 24 and the two diverter plates 28.

[0049] The distance between the two guide plates 24 and the distance between the two diverter plates 28 can be adjusted according to the size of the bird's nest cans. Driven by the material conveyor 2, the cans pass under the high-frequency cameras 21 fixed on the mounting frame 20. Multiple high-frequency cameras 21 capture images of each can quickly and continuously from preset angles. The images are transmitted to the control system for real-time analysis and processing (such as defect identification, label OCR / OCV, liquid level detection, etc.). The control system determines whether the current can is qualified based on the image analysis algorithm. If the can is unqualified (or belongs to the type that needs to be withdrawn, such as empty cans, damaged cans, incorrect labels, etc.), the control system issues a command to release the material. The sliding seat of the moving screw 22 drives the feeding plate frame 23 to push the can onto the return conveyor 14, and outputs it in the opposite direction for return. If the can is qualified, the control system issues a command to the diversion mechanism 3 to guide the can to continue to be conveyed backward along the guide conveyor 2. It first contacts the trumpet-shaped guide plate 24. The trumpet design naturally gathers and centrally arranges the can, which then enters the interior of the two diversion plates 28. The diversion motor 26 drives the diversion drive rod 27 to rotate to a specific angle, so that the two diversion plates 28 are in the "straight" position. At this time, the diversion plates 28 are successively matched with the inlet of the guide channel, and the can flows into the corresponding guide channel of the guide mechanism 4, and is conveyed backward evenly.

[0050] The material stopping braking mechanism 13 includes a side fixing plate 29, which is fixed to the rear right side of the conveying frame 1. An adjusting seat 32 is adjustablely provided on the side fixing plate 29. A material equalization braking push rod 31 is fixed on the adjusting seat 32. A moving plate 30 is slidably provided on the adjusting seat 32. The telescopic end of the material equalization braking push rod 31 is fixedly connected to the moving plate 30. A braking crossbeam 34 is fixed on the moving plate 30. The braking crossbeam 34 is located at the upper end of the material guiding conveyor 2. Several equally spaced braking plates 33 are adjustablely provided on the braking crossbeam 34. The position and number of the braking plates 33 correspond to the guide channel.

[0051] Adjusting the position of the adjusting seat 32 on the side fixing plate 29 allows for overall adjustment of the position of each braking actuator (push rod, moving plate, braking crossbeam, braking plate) relative to the canned food flow on the material conveyor 2, ensuring that the braking action occurs at a precise preset work point; the equalizing braking push rod 31 drives the moving plate 30 to slide back and forth on the adjusting seat 32, driving the braking crossbeam 34 and all braking plates 33 to slide back and forth, used to adjust the position of the braking plates 33 to adapt to the placement and positioning of bird's nest cans of different sizes; driven by the material conveyor 2, the cans pass through the area unimpeded in their respective guide channels and flow to the subsequent transfer work station, that is, the cans are stably stopped at the can transfer mechanism 6.

[0052] The material blocking braking mechanism 5 includes a brake frame 35, which is fixed above the conveying frame 1. Two drive screws 38 are rotatably mounted on the brake frame 35, and a pulley pair is provided between the two drive screws 38. An adjustment handwheel 37 is fixed to the upper end of one of the drive screws 38. A lifting plate 36 is slidably mounted on the inner side of the brake frame 35. The lifting plate 36 is screwed and driven by the two drive screws 38. A vertically arranged material blocking brake push rod 39 is fixed on the lifting plate 36. A brake cross plate 40 is fixed to the telescopic end of the material blocking brake push rod 39. Several equally spaced brake pins 41 are detachably mounted on the brake cross plate 40. The position and number of brake pins 41 correspond to the guide channel.

[0053] Initial height adjustment: The operator rotates the adjustment handwheel 37, which drives the connected drive screw 38 to rotate. The two drive screws 38 rotate synchronously through the pulley pair. The rotation of the drive screws 38 drives the lifting plate 36 to rise and fall vertically along the brake frame 35. The entire braking actuation assembly (stop brake push rod 39, brake cross plate 40, brake column 41) fixed on the lifting plate 36 rises and falls synchronously. Adjust the end of the brake column 41 to a position slightly higher than the top of the target can (or set a reference height according to process requirements). After adjustment, the screw's self-locking characteristic or an additional locking device will hold the position. Normal operation / brake release ( Automatic, Normal): The material-stopping brake push rod 39 is in the retracted state; the entire brake column 41 assembly (push rod extension end, brake plate 40, brake column 41) is in a high position; the end of the brake column 41 is higher than the guide channel below; the cans, driven by the material conveyor 2, pass through the area unimpeded in their respective guide channels; Triggered Braking / Precise Positioning (Automatic, On Demand): When the control system determines that the can needs to be precisely positioned below the material-stopping brake mechanism 5 (e.g., the can is about to reach the transfer point, a certain detection or operation needs to be performed at this station, or to ensure synchronization with subsequent mechanisms), it issues an extension command to the material-stopping brake push rod 39; Material-stopping... The telescopic end of the brake push rod 39 extends rapidly downwards, and the thrust is transmitted through the telescopic end to the brake cross plate 40 fixed to it. The brake cross plate 40 drives all the brake pins 41 to move downwards synchronously, and the ends of the brake pins 41 are precisely inserted into their respective guide channels. The cans that are moving forward in the guide channel (the one at the front of the channel queue) are directly blocked by the ends of the brake pins 41 and immediately stop on the conveyor belt. The cans are fixed in a precise preset position, which is determined by the end of the push rod's stroke and the previously manually adjusted height. The cans in the same channel continue to be conveyed forward and naturally queue up and accumulate behind the brake pins 41. At this time, the cans are in The system is precisely positioned and awaits subsequent actions (such as being grabbed by the can transfer mechanism 6, undergoing specific inspections, etc.). When the subsequent actions are completed (such as successful transfer), the control system sends a retraction command to the stop brake push rod 39. The telescopic end of the stop brake push rod 39 quickly retracts upward. The pulling force pulls the brake plate 40 through the telescopic end. All brake pins 41 move upward synchronously. The ends of the brake pins 41 completely exit the guide channel, clearing the channel path. The obstruction is released, and the can that was blocked and positioned (the one at the front of each channel queue) immediately resumes movement under the drive of the conveyor belt and flows to the next workstation. The queue of cans that have accumulated in the queue also moves forward in sequence.

[0054] The canned food transfer mechanism 6 includes a transverse electric screw component 42, which is fixed on the conveying frame 1. A vertical electric screw component 43 is provided on the sliding seat of the transverse electric screw component 42. A transfer frame 44 is detachably provided on the sliding seat of the vertical electric screw component 43. Several sets of evenly distributed transfer suction cups 45 are provided on the transfer frame 44. The transfer suction cups 45 are connected to an external vacuum pump.

[0055] The horizontal electric screw 42 moves the vertical electric screw 43 and the transfer frame 44 to directly above the guide conveyor 2, corresponding to the position of the guide channel; the vertical electric screw 43 raises the transfer frame 44 to a high position, and the transfer suction cups 45 move away from the cans; the control system confirms that the cans in the guide channel have been accurately positioned at the gripping point under the action of the material blocking braking mechanism 5 or a similar mechanism; the vertical electric screw 43 drives its sliding seat to descend rapidly, causing the transfer frame 44 and several sets of evenly distributed transfer suction cups 45 to move downwards, and the several sets of evenly distributed transfer suction cups 45 contact the top surface of the cans; the vacuum solenoid valve opens, the vacuum pump works, and negative pressure is generated in the transfer suction cups 45, firmly adsorbing the target cans, and several cans corresponding to each guide channel are grabbed by a set of suction cups above them; the vertical electric screw 43 drives the sliding seat to rise rapidly, moving the cans into the guide channel. The transfer frame 44, holding the can, is raised to a safe height, completely removing the can from the surface and flow channel of the material conveyor 2. The transverse electric screw 42 drives its sliding seat to move precisely, horizontally moving the entire vertical gripping component holding the can to the designated packing position above the double-position conveyor 11. The vertical electric screw 43 then drives the sliding seat to descend precisely, placing the can at the designated point on the target double-position conveyor, while the transfer suction cup 45 remains attached. After reaching the predetermined release height, the vacuum solenoid valve closes, releasing the negative pressure, and the transfer suction cup 45 separates from the top surface of the can, allowing the can to be precisely released. The vertical electric screw 43 raises the unloaded transfer frame 44 to a high position. The transverse electric screw 42 drives the entire mechanism to move horizontally back to the initial gripping position above the material conveyor 2, awaiting the next work cycle.

[0056] The guard plate transfer mechanism 7 includes a second horizontal electric lead screw 47, which is fixed on the conveying frame 1. A second vertical electric lead screw 46 is provided on the sliding seat of the second horizontal electric lead screw 47. An adjusting frame 48 is fixed on the sliding seat of the second vertical electric lead screw 46. A second transfer frame 50 is detachably provided on the adjusting frame 48. A row of evenly distributed transfer suction cups 49 is provided on the transfer frame 50. The transfer suction cups 49 are connected to an external vacuum pump.

[0057] The second horizontal electric screw 47 moves the second vertical electric screw 46, the adjusting frame 48, and the second transfer frame 50 to a position directly above the guard plate feeding mechanism 12, ready for gripping. The second vertical electric screw 46 raises the entire gripping head to a high position, the vacuum system is turned off, and the control system confirms that the guard plate feeding mechanism 12 is ready to grip a guard plate. The second vertical electric screw 46 drives its sliding seat to descend precisely and smoothly, and the second transfer suction cup 49 evenly contacts the upper surface of the guard plate. The vacuum is turned on, and negative pressure is generated inside the second transfer suction cup 49, flattening and adsorbing the guard plate. The second vertical electric screw 46 continues to raise the gripping head to a safe height, causing the guard plate to leave the feeding area. The second horizontal electric screw 47 drives its sliding seat to move precisely, adsorbing the guard plate. The entire mechanism with the protective plate is horizontally moved to the target placement position above the double-position conveyor 11 (e.g., above a row of cans or a specific placement station on the double-position conveyor); the vertical electric screw 46 drives the sliding seat to descend precisely and slowly, smoothly bringing the protective plate close to the target placement surface; when the protective plate is about to touch or slightly touches the placement surface, the vacuum is closed, releasing the suction force; the protective plate lands at the target position; the vertical electric screw 46 immediately drives the sliding seat to lift, causing the suction cup to detach from the protective plate; the vertical electric screw 46 lifts the unloaded gripping head to a high position; the horizontal electric screw 47 drives the entire mechanism to move horizontally back to the initial gripping position above the protective plate unloading mechanism 12, awaiting the next gripping command.

[0058] The guard plate feeding mechanism 12 includes a plate collection frame 51, a rotating shaft 53, and a feeding motor 57. The plate collection frame 51 is adjustablely hinged to the rear left side of the conveying frame 1. A baffle 52 is hinged on the plate collection frame 51. The rotating shaft 53 is rotatably mounted on the conveying frame 1. A second moving rod and two feeding racks 55 are adjustablely mounted on the rotating shaft 53. Several feeding suction cups 54 are provided at the upper end of each feeding rack 55. The feeding motor 57 is fixed on the conveying frame 1. A first moving rod is fixed on the output shaft of the feeding motor 57. A drive connecting rod 56 is hinged between the first moving rod and the second moving rod.

[0059] The feeding motor 57 drives the first moving rod to rotate to a specific angle, which pushes / pulls the second moving rod through the drive linkage 56. The second moving rod drives the rotating shaft 53 to rotate to the picking angle. The two feeding racks 55 fixed on the rotating shaft 53 and their feeding suction cups 54 are positioned directly above the uppermost protective plate of the plate holder 51. The suction cups are vertically downward or slightly tilted and aligned with the protective plate. The vacuum system is closed, and the feeding suction cups 54 descend and pick up the material. The feeding suction cups 54 contact the surface of the uppermost protective plate, the vacuum is turned on, and the feeding suction cups 54 adsorb the uppermost protective plate. The output shaft of the feeding motor 57 drives the first moving rod to rotate continuously. The rotational motion of the first moving rod is converted into the reciprocating rocking motion of the second moving rod through the drive linkage 56. The rocking motion of the second moving rod drives the rotating shaft 53 to rotate. The two feeding racks 55, the feeding suction cups 54, and their suction cups 54 fixed on the rotating shaft 53 rotate. The attached guard plate rotates synchronously; the guard plate is flipped from its near-vertical / tilted storage posture above the collection rack 51 to a near-horizontal release posture; when the discharge rack 55 rotates to the predetermined discharge angle (horizontal or slightly tilted), the vacuum is closed, and the guard plate smoothly detaches from the discharge suction cup 54 under the action of gravity and falls to the predetermined waiting position below. This position is the gripping starting point of the guard plate transfer mechanism 7. The transfer suction cup 49 of the guard plate transfer mechanism 7 then descends to grip the released guard plate; the discharge motor 57 continues to rotate (or reverses), driving the first moving rod to return to the initial angle, and driving the second moving rod to rock in the opposite direction through the drive linkage 56. The rotating shaft 53 rotates in the opposite direction, causing the unloaded discharge rack 55 and the discharge suction cup 54 to flip back to the picking position above the collection rack 51, ready for the next picking cycle.

[0060] The box frame assembly 8 includes a box frame body 58. The box frame body 58 has electric push rods 59 for blocking boxes on both the left and right sides inside. A fixed box frame 61 is fixed between the lower ends of the electric push rods 59. Several boxes 60 are placed above the box conveyor line 10. A main control computer 62 is provided on the side of the box frame body 58.

[0061] Several empty packaging boxes 60 are placed above the box conveyor line 10 and are sequentially conveyed by the box conveyor line 10 to the position directly opposite the double-position conveyor 11 inside the box frame assembly 8. The box-blocking electric push rod 59 drives the fixed box frame 61 to descend, and the fixed box frame 61 presses against the empty packaging box 60 that is ready to be filled with canned goods, ensuring that the empty packaging box 60 is in a stable position, which facilitates the filling of canned goods. After the filling is completed, the box-blocking electric push rod 59 drives the fixed box frame 61 to rise, and the fixed box frame 61 releases the pressing on the packaging box 60. The box conveyor line 10 sequentially conveys the packaging boxes 60 out of the box frame assembly 8 and to the downstream workstation. The main control computer 62 is a human-machine interface (HMI) of an industrial control computer (IPC) or a programmable logic controller (PLC), which sets or adjusts the operating parameters of relevant equipment and serves as a local control unit or monitoring terminal.

[0062] The frame assembly 8 includes a fixing plate 63, which is fixed to the top front side inside the frame body 58. A synchronizing rod 73 and two connecting arms 64 are hinged to the side of the fixing plate 63. Connecting arms 65 are hinged to the ends of both connecting arms 64. A synchronizing triangular connecting plate 71 is hinged to the hinge axis of the connecting arms 64 and 65. A fixing frame 66 is hinged to the ends of the two connecting arms 65. A synchronizing rod 70 is hinged to the fixing frame 66. The synchronizing rod 70 and synchronizing rod 73 are respectively hinged to the two ends of the synchronizing triangular connecting plate 71. A second transport motor 74 is fixed to the fixing plate 63. The output shaft of the second transport motor 74 is connected to the hinge shaft of the fixed plate 63 and the first connecting arm 64. One of the connecting arms 65 is fixed with a first transport motor 72. The output shaft of the first transport motor 72 is connected to the hinge shaft of the first connecting arm 64 and the second connecting arm 65. The lower end of the fixed frame 66 is provided with an adjusting electric screw 67. Several suction cup frames 69 are fixed on the sliding seat of the adjusting electric screw 67. The suction cup frames 69 are slidably arranged on the adjusting electric screw 67. The lower end of the suction cup frames 69 is provided with several sets of evenly distributed transfer suction cups 68. The transfer suction cups 68 are connected to an external vacuum pump.

[0063] The second transport motor 74 and the first transport motor 72 place the mechanism in a safe high position, usually near the upper side of the box frame body 58. The electric lead screw 67 is adjusted to place the suction cup frame 69 in the default or previous task width position. The vacuum system is turned off, and the control system receives a signal that the can layers on the double-position conveyor 11 are arranged and the empty packaging boxes 60 in the box frame body 58 are ready. The second transport motor 74 drives the first connecting arm 64 to rotate, causing the entire mechanism to swing downward and forward, moving it to directly above the arranged layers on the double-position conveyor 11. The first transport motor 72 drives the second connecting arm 65 to rotate, making fine adjustments to its position and attitude, so that several sets of transfer suction cups 68 are precisely aligned with the can layers or the protective plates. With the coordinated action of the second transport motor 74 and the first transport motor 72, the transfer suction cups 68 contact the top surface of the arranged can layers or the uppermost protective plate. When the vacuum is activated, all the material suction cups 68 adsorb the entire layer of material. The second transport motor 74 drives the first connecting arm 64 to rotate in the opposite direction. At the same time, the first transport motor 72 coordinates with the second connecting arm 65 to lift the part adsorbing the entire layer of material to a high position and swing it backward and upward, moving it towards the empty packaging box 60 inside the box frame body 58. The second synchronous rod 70, the first synchronous rod 73, and the synchronous triangular connecting plate 71 work together to ensure that the fixed frame 66 remains horizontal during the transfer process. The coordinated action of the second transport motor 74 and the first transport motor 72 drives the end of the mechanism to descend smoothly, placing the material layer into the empty packaging box 60. When the predetermined depth is reached, the vacuum is closed, releasing the entire layer of material. The coordinated action of the second transport motor 74 and the first transport motor 72 lifts the empty part and swings it back to the initial high standby position, waiting for the next cycle.

[0065] Flow guidance and queue control: The cans enter the flow channel of the flow guiding mechanism 4 (composed of side baffle 17 and flow guide plate 18): The channel spacing is adapted to the can size by adjusting the locking block 16, forcing the cans to be arranged in a single row; the material blocking block 19 is controlled by the material blocking motor: Falling state: blocking the cans at the front of the channel to form a queue; Lifting state: releasing the cans to the next station according to the rhythm.

[0066] Precise positioning and transfer preparation: Material blocking brake mechanism 5: Rotate the adjustment handwheel 37 to adjust the height of the brake column 41 to match the size of the can; the material blocking brake push rod 39 drives the brake column 41 to insert downwards, accurately positioning the can at the transfer point; Material stopping brake mechanism 13: Adjust the position of the brake plate 33 through the adjustment seat 32 to pause the conveying as needed in the can transfer area and coordinate the transfer rhythm.

[0067] Coordinated transfer of cans and protective plates: Protective plate feeding mechanism 12: The plate holder 51 stores the protective plates (partitions) at an adjustable tilt angle; The feeding motor 57 drives the four-bar linkage (moving rod one, moving rod two, driving connecting rod 56) to make the feeding suction cup 54 adsorb the uppermost protective plate and rotate it 90° to the horizontal release position; Protective plate transfer mechanism 7: Transfer suction cup two 49 grabs the protective plate → Vertical electric screw two 46 and horizontal electric screw two 47 place it at the front end of the double-position conveyor 11; Can transfer mechanism 6: Transfer suction cup one 45 grabs the positioned can → Horizontal electric screw one 42 and vertical electric screw one 43 transfer it to the protective plate of the double-position conveyor 11; Circular stacking: Repeat the transfer action to form an alternating stacking structure of "protective plate-can layer-protective plate" on the double-position conveyor 11 (both the bottom and top layers are protective plates).

[0068] Empty box supply and full-layer packing: Box frame assembly 8: The electric push rod 59 extends → lifts the upper layer of empty box stacks, and the bottom empty box is precisely positioned on the fixed box frame 61; the box conveyor line 10 transports the empty boxes to the packing station; Packing and handling mechanism 9: Step 1: The second handling motor 74 drives the connecting arm 64, and the first handling motor 72 adjusts the connecting arm 65 so that the transfer suction cup 68 is aligned with the stacked layer on the double-position conveyor 11; Step 2: The suction cup adsorbs the entire layer → the synchronization mechanism (synchronization rod 70, synchronization triangular connecting plate 71, synchronization rod 73) keeps it horizontal → transfers it above the empty box; Step 3: The electric lead screw 67 finely adjusts the suction cup spacing → the entire layer is placed into the box → vacuum release; Full box output: The electric push rod 59 retracts → the box stack descends one layer → the new empty box is in place; the box conveyor line 10 sends the full box downstream (sealing / palletizing).

[0069] In summary, continuous conveying of canned bird's nest is achieved through the material conveyor 2. The path and position of the cans are precisely controlled by the diversion mechanism 3, the guide mechanism 4, the material blocking braking mechanism 5, and the stopping braking mechanism 13. The protective plate transfer mechanism 7 works in conjunction with the protective plate unloading mechanism 12 to stably transfer and place the protective plates. The can transfer mechanism 6 and the protective plate transfer mechanism 7, under the coordinated work of the double-position conveyor 11, complete the combination arrangement of cans and protective plates. The combination method can be selected flexibly to avoid collision damage to the canned bird's nest after packing, effectively protecting the canned bird's nest and reducing loss costs. The box frame assembly 8 and the box conveyor line 10 transport empty boxes, while the boxing and handling mechanism 9 performs the key gripping and packing actions. The diversion mechanism 3 works in conjunction with the retraction conveyor 14 to screen and reverse transport abnormal products, ensuring the quality of the canned bird's nest and reducing loss costs. The entire system is compact in design, highly automated, and all components work together to achieve an efficient and automated conveying process for canned bird's nest from finished product to boxed product, emphasizing product protection and precise positioning.
