Description

Technical Field

[0001] This invention relates to the field of bird's nest production, processing and conveying, and in particular to a bird's nest production, processing and conveying device and method. Background Technology

[0002] In the production and processing of bowl-packaged bird's nest, conveying and stacking are crucial steps. Currently, the industry mostly uses manual labor combined with simple conveyor equipment to complete this operation. When manual labor is involved in loading and stacking bowl-packaged bird's nest, the overall efficiency is low due to excessive human intervention in the operation steps. It is difficult to match the rhythm of automated bird's nest production, and the randomness of manual operation can easily lead to problems such as irregular stacking of bowl-packaged bird's nest. In fact, operational errors may even cause the bowl-packaged bird's nest to be bumped and damaged.

[0003] In addition, existing conveying equipment can only realize one-way transmission of bird's nests, and cannot efficiently complete the linkage operation of automatic loading and stacking. The equipment has limited functionality and lacks an automated linkage structure that is compatible with the bird's nest production process, making it difficult to meet the processing needs of large-scale bird's nest production. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention provides a bird's nest production and processing conveying device, including a set of turnover conveyor belts, a placement gap between the set of turnover conveyor belts, and a base frame located below the placement gap. A base frame is guided and mounted on the base frame. The base frame is equipped with a first limit switch and a second limit switch that cooperate with the movement range of the base frame. The base frame is equipped with a photoelectric emitting module that detects vertically upwards, and a photoelectric receiving module that cooperates with the photoelectric emitting module is arranged above the placement gap. A support platform is provided on the top of the base frame, on which multiple layers of trays are stacked. Each tray has multiple bowl grooves and a through hole that vertically penetrates the bowl groove. Lifters are arranged on both sides of the base frame, and the output end of the lifters is driven and connected to a lifting component for vertically lifting and lowering the trays. A lifting component and a displacement module that drives the lifting component to move horizontally are also arranged above the base frame. An inner lining partition is stacked in the area below the horizontal movement path of the lifting component driven by the displacement module. The output end of the lifting component faces downwards and is connected to a lifting frame. Multiple suction cups that adhere to and cooperate with the trays and inner lining partitions are arranged at the bottom of the lifting frame.

[0006] Preferably, a motor is fixedly installed at one end of the base frame, and the output end of the motor is connected to a lead screw. A drive block with a transverse threaded through hole is provided on the bottom side of the base frame, and the lead screw is screwed and passes through the drive block. Two sliders are also provided on the bottom side of the base frame, one slider cooperating with a first limit switch and the other slider cooperating with a second limit switch.

[0007] Preferably, the support platform has a monitoring through hole aligned with the photoelectric emission module, and the perforation of the tray is aligned with the monitoring through hole.

[0008] Preferably, the tray has a bowl-shaped groove for holding bowl-shaped bird's nest, and the top surface of the bowl-shaped bird's nest does not protrude from the top surface of the tray.

[0009] Preferably, an interlayer gap is formed between adjacent pallets placed on the upper side of the support platform; a lifting shaft is provided at the output end of the lifter, and the lifting assembly includes a top plate fixedly connected to the lifting shaft. A photoelectric probe is arranged in the middle of the top plate, and a set of micro cylinders is also fixedly installed on the top plate. The output end of the micro cylinders is connected to a plug rod, and the photoelectric probe, plug rod and interlayer gap are aligned and cooperate.

[0010] Preferably, the displacement module includes a guide rod, a displacement drive mechanism mounted on the guide rod, and a lifting assembly fixedly mounted on the bottom side of the displacement drive mechanism.

[0011] Preferably, the top side of the tray is provided with multiple protrusions, and the inner lining partition is provided with a groove that matches the protrusions.

[0012] Preferably, the top surface of the tray has a first smooth area that mates with the suction cup, and the top surface of the inner liner has a second smooth area that mates with the suction cup.

[0013] The present invention also provides a method for conveying bird's nest during production and processing, applied to the aforementioned bird's nest production and processing conveying device, comprising the following steps:

[0014] Step 1: The packaged bird's nest in bowls is conveyed forward along the gaps between a set of conveyor belts. Step 2: The base frame is in its initial position and triggers the first limit switch. The photoelectric transmitting module and photoelectric receiving module align, and the photoelectric receiving module receives the signal from the photoelectric transmitting module. Step 3: The lifting device, through the lifting assembly, moves the top tray vertically upward to a preset height. Step 4: When the bird's nest in the bowl blocks the photoelectric signal, the motor drives the base frame to move synchronously with the bird's nest until the signal is restored, at which point the motor stops, and the bird's nest falls into the bowl slot of the tray. Step 5: Steps 3 and 4 are repeated until all the bowl slots of the tray are filled with bird's nest, and the signal from the photoelectric transmitting module is completely blocked. Step 6: The motor drives the base frame to move laterally until the base frame triggers the second limit switch, at which point the motor stops. Step 7: The lifting assembly moves the lifting frame downward, allowing the suction cup to contact and adhere to the fully loaded tray. Step 8: The lifting device lowers the lifting assembly, and the motor drives the base frame back to its initial position. Steps 2 through 5 are repeated to load the next tray. Step Nine: The lifting assembly moves the suction cup holding the tray upwards, and the displacement module moves the tray directly above the packaging box. The lifting assembly then moves the tray downwards into the packaging box, after which the suction cup releases the tray. Step Ten: The lifting assembly moves the suction cup upwards, and the displacement module moves the suction cup to the inner lining partition stacking area. The suction cup adheres to the inner lining partition and places it on top of the tray inside the packaging box. Step Eleven: The displacement module moves the suction cup back above the base frame. When the base frame triggers the second limit switch again, steps Seven through Ten are repeated to complete the subsequent stacking operation.

[0015] Compared with existing technologies, the beneficial effects of this invention are:

[0016] This invention automates the conveying and stacking of bowl-packaged bird's nest during production, eliminating the need for manual loading and stacking. This significantly improves the conveying efficiency of bird's nest production and processing, matching the pace of large-scale bird's nest production. Simultaneously, through precise control of the mechanical structure, this invention ensures the neatness of the bowl-packaged bird's nest stacking, avoiding the disorder caused by manual operation and reducing damage from human error, thus increasing the yield of finished bird's nest. Furthermore, the various components of the device are highly interconnected and the operation flow is smooth, making it suitable for automated conveying and stacking processes in bird's nest production.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] Example 1

[0029] like Figure 1 , Figure 2 As shown, the bird's nest production and processing conveying device provided in this embodiment is equipped with a set of turnover conveyor belts 1. A placement gap 101 is reserved between the turnover conveyor belts 1 for the bowl-shaped bird's nest 2 to pass through. A base frame 3 is fixedly arranged below the placement gap 101. The base frame 3 is the basic support structure of the device. A horizontally movable base frame 6 is guided and installed above the base frame 3. A first limit switch 301 and a second limit switch 302 are also installed on the base frame 3. The two limit switches are adapted to the movement range of the base frame 6 to realize the movement limit of the base frame 6. A photoelectric emitting module 13 for vertical upward detection is installed on the base frame 6. A photoelectric receiving module 14 is correspondingly installed above the placement gap 101. The photoelectric receiving module 14 cooperates with the photoelectric emitting module 13 to realize the detection of the position of the bowl-shaped bird's nest 2 by the on and off of the photoelectric signal.

[0030] like Figure 1 , Figure 3 , Figure 5 , Figure 8As shown, a support platform 601 is integrally formed on the top of the base frame 6. Multiple layers of trays 11 are stacked on the support platform 601. The trays 11 have multiple bowl grooves 1101, which are the placement positions for bowl-shaped bird's nests 2. The trays 11 also have vertical through holes 1102 that penetrate the bowl grooves 1101. The support platform 601 has a monitoring through hole 6011 aligned with the photoelectric emission module 13. The through hole 1102 of the tray 11 is aligned with the monitoring through hole 6011 to ensure that the signal from the photoelectric emission module 13 can penetrate upward through the tray 11. The bowl grooves 1101 of the tray 11 are used to place the bowl-shaped bird's nests 2. After the bowl-shaped bird's nests 2 are placed in the bowl grooves 1101, their top surfaces do not protrude from the top surfaces of the tray 11 to avoid collisions during subsequent stacking. A gap 12 is formed between adjacent trays 11 on the upper side of the support platform 601 to provide space for the operation of the lifting components.

[0031] like Figure 1 , Figure 3 , Figure 4 As shown, lifting devices 7 are symmetrically arranged on both sides of the base frame 6. The output end of the lifting device 7 is fixedly connected to the lifting shaft 701. A lifting assembly is driven and connected to the lifting shaft 701. The lifting assembly is the core structure that drives the pallet 11 to rise and fall vertically. It includes a top plate 8 fixedly connected to the lifting shaft 701. A photoelectric probe 801 is installed in the middle of the top plate 8. A set of micro cylinders 9 is also fixedly installed on the top plate 8. The output end of the micro cylinder 9 is connected to the insertion rod 10. The photoelectric probe 801 and the insertion rod 10 are aligned and cooperate with the interlayer gap 12. The photoelectric probe 801 can detect the position of the interlayer gap 12. After the micro cylinder 9 drives the insertion rod 10 to extend into the interlayer gap 12, the pallet 11 can be accurately lifted.

[0032] like Figure 1 , Figure 3 As shown, a motor 4 is bolted to one end of the base frame 3. The motor 4 is the power source for the movement of the base frame 6. A lead screw 5 is coaxially connected to the output end of the motor 4. A drive block 602 is welded to the bottom side of the base frame 6. A transverse threaded through hole is provided on the drive block 602. The lead screw 5 is screwed into and passes through this transverse threaded through hole. When the motor 4 is running, the rotation of the lead screw 5 drives the drive block 602 to move laterally, thereby driving the base frame 6 to move smoothly along the guide of the base frame 3. Two sliders 603 are also bolted to the bottom side of the base frame 6. One slider 603 cooperates with the first limit switch 301, and the other slider 603 cooperates with the second limit switch 302. When the base frame 6 moves, the slider 603 triggers the limit switch, which can realize the automatic stop of the base frame 6 and complete the movement limit.

[0033] like Figure 1 , Figure 6 , Figure 7As shown, a lifting assembly 15 and a displacement module for driving the lifting assembly 15 to move horizontally are also configured above the base frame 3. The displacement module includes a guide rod 18 and a displacement drive mechanism 19 mounted on the guide rod 18. The lifting assembly 15 is fixedly mounted on the bottom side of the displacement drive mechanism 19 by bolts. The displacement drive mechanism 19 can drive the lifting assembly 15 to move horizontally along the guide rod 18. Inner lining partitions 20 are stacked in the area below the path of the displacement module driving the lifting assembly 15 to move horizontally. The output end of the lifting assembly 15 faces downward and is fixedly connected to a lifting frame 16. Multiple suction cups 17 are evenly arranged at the bottom end of the lifting frame 16. The suction cups 17 can achieve a tight adsorption fit with the tray 11 and the inner lining partition 20 to complete the transfer of the tray 11 and the inner lining partition 20.

[0034] like Figure 5 , Figure 8 , Figure 9 As shown, the top side of the tray 11 is integrally formed with multiple protrusions 1103. The inner lining partition 20 has a groove 2001 that mates with the protrusions 1103. After the protrusions 1103 are inserted into the groove 2001, the inner lining partition 20 and the tray 11 can be precisely engaged and positioned, preventing misalignment during stacking. The top surface of the tray 11 has a first smooth area 1104, and the top surface of the inner lining partition 20 has a second smooth area 2002. Both the first smooth area 1104 and the second smooth area 2002 mate with the suction cup 17, which can improve the sealing between the suction cup 17 and the tray 11 and the inner lining partition 20, and enhance the adsorption stability.

[0035] Example 2

[0036] The bird's nest production, processing, and conveying method provided in this embodiment is applied to the aforementioned bird's nest production, processing, and conveying device, and specifically includes the following steps:

[0037] The packaged bird's nest 2 is fed into a set of turnover conveyor belts 1 through a conveying mechanism. Then, the bird's nest 2 is continuously conveyed forward along the placement gap 101 and enters the loading operation area of ​​the device.

[0038] In the initial stage of operation, the base frame 6 is in the initial position of the base frame 3. The slider 603 on the bottom side of the base frame 6 triggers the first limit switch 301. At this time, the photoelectric emitting module 13 on the base frame 6 is precisely aligned with the photoelectric receiving module 14 above the placement gap 101. The photoelectric receiving module 14 can stably receive the detection signal emitted vertically upward by the photoelectric emitting module 13.

[0039] After the base frame 6 is stabilized, the lifting device 7 is activated and the lifting shaft 701 drives the lifting component to move upward. The insertion rod 10 of the lifting component extends into the gap 12 between the top tray 11 and the bottom tray 11, and then drives the top tray 11 to move vertically upward to the preset height, which is the preset loading height of the bowl-shaped bird's nest 2, ensuring that the bowl-shaped bird's nest 2 can fall smoothly into the corresponding bowl groove 1101.

[0040] When the bowl-shaped bird's nest 2 moves directly above the photoelectric emitting module 13, it blocks the photoelectric signal, and the photoelectric receiving module 14 cannot receive the signal from the photoelectric emitting module 13. At this time, the motor 4 starts and drives the lead screw 5 to rotate. The lead screw 5 drives the drive block 602 to move synchronously with the base frame 6. The moving speed of the base frame 6 is consistent with the moving speed of the bowl-shaped bird's nest 2 driven by the turnover conveyor belt 1 until the bowl-shaped bird's nest 2 moves directly above the bowl groove 1101 of the tray 11. The photoelectric signal is restored. After the photoelectric receiving module 14 receives the signal again, the motor 4 stops immediately. Under the action of gravity, the bowl-shaped bird's nest 2 falls into the bowl groove 1101 of the tray 11 directly below it, completing the loading of a single bowl-shaped bird's nest 2.

[0041] Repeat the above operation, with motor 4 controlling the movement and stopping of base frame 6, until all bowls 1101 on tray 11 are fully loaded with bird's nest 2. At this time, the signals emitted upward by all photoelectric transmitting modules 13 on base frame 6 are blocked by bird's nest 2, and photoelectric receiving modules 14 are unable to receive signals.

[0042] After the pallet 11 is fully loaded, the motor 4 starts again and drives the base frame 6 to move laterally away from the initial position until another slider 603 on the bottom side of the base frame 6 triggers the second limit switch 302, the motor 4 stops running, and the base frame 6 stops at the stacking operation station, waiting for the transfer operation of the suction cup 17.

[0043] After the base frame 6 comes to a stop, the lifting assembly 15 starts and drives the lifting frame 16 to move vertically downward until all the suction cups 17 at the bottom of the lifting frame 16 are in close contact with the first smooth area 1104 on the top surface of the fully loaded tray 11. After the suction cups 17 are pumped out to form a negative pressure, the suction cups 17 complete the adsorption and fixation of the tray 11.

[0044] After the suction cup 17 completes adsorption, the lifting device 7 drives the lifting assembly to move downwards, and the insertion rod 10 is pulled out from the interlayer gap 12, releasing the lifting of the fully loaded pallet 11. Then the motor 4 rotates in the opposite direction, driving the base frame 6 to return to the initial position along the lead screw 5. The base frame 6 stops after triggering the first limit switch 301. Then the operation of steps 2 to 5 is repeated to start loading the next empty pallet 11 with the bowl-shaped bird's nest 2, realizing the linkage operation of loading and stacking.

[0045] After the suction cup 17 adheres to the fully loaded pallet 11, the lifting assembly 15 drives the lifting frame 16 and the pallet 11 to move vertically upward to a preset height to prevent the pallet 11 from colliding with other structures. Then, the displacement drive mechanism 19 is activated, driving the lifting assembly 15 to move horizontally along the guide rod 18, moving the adhered pallet 11 directly above the open packaging box 21. The lifting assembly 15 then drives the lifting frame 16 to move downward again, placing the pallet 11 stably inside the packaging box 21. Afterward, the suction cup 17 releases air to relieve the negative pressure and releases the pallet 11.

[0046] After the tray 11 is placed, the lifting assembly 15 moves the suction cup 17 vertically upward. The displacement drive mechanism 19 moves the lifting assembly 15 and the suction cup 17 horizontally to directly above the stacking area of ​​the inner lining partition 20. The lifting assembly 15 moves the suction cup 17 downward, so that the suction cup 17 contacts the second smooth area 2002 on the top surface of the inner lining partition 20 and completes adsorption. Then, the lifting assembly 15 cooperates with the displacement module to move the inner lining partition 20 to the upper side of the tray 11 in the packaging box 21, so that the slot 2001 of the inner lining partition 20 and the protrusion 1103 of the tray 11 are precisely engaged, completing the stacking of the inner lining partition 20 and preparing for the placement of the next layer of tray 11.

[0047] After the inner lining partition 20 is placed, the displacement module drives the lifting component 15 and the suction cup 17 back to the working area above the base frame 3, waiting for the base frame 6 to complete the loading of the next pallet 11 and trigger the second limit switch 302. Then the above operation is repeated to complete the alternating stacking of the subsequent pallets 11 and inner lining partition 20.

[0048] In the actual equipment control process, it is necessary to precisely control the overall time for the suction cup 17 to adsorb, grab, and place the pallet 11 and the inner lining partition 20. This time must be less than the time it takes for a single pallet 11 on the base frame 6 to complete a full load of the bowl-shaped bird's nest 2 and complete a lateral back-and-forth movement. This ensures that the loading and stacking operations of the device are carried out continuously, thereby improving the overall conveying and stacking efficiency.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
