Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of counting packaging equipment, in particular to an automatic egg product counting machine. BACKGROUND

[0002] In the food processing industry, especially in the egg product industry, the introduction of automated production lines has greatly improved production efficiency, reduced labor costs, and ensured the stability of product quality. However, in the packaging process of egg products, one of the key and challenging steps is accurate counting. Due to the different shapes, sizes, and surface characteristics of egg products (such as chicken eggs, duck eggs, etc.), traditional counting methods often rely on manual operation, which is not only inefficient but also prone to errors, especially on high-speed production lines, counting errors will significantly increase, affecting the packaging accuracy and market acceptance of the final product.

[0003] Traditional counting methods include using photoelectric sensors for individual detection, but this method is prone to missed or false detections when faced with closely stacked or irregularly shaped egg products. In addition, directly using mechanical arms or conveyors for simple separation and counting often results in inaccurate counting results due to factors such as friction and adhesion between egg products.

[0004] To overcome these difficulties, some automated counting and packaging equipment has gradually appeared on the market, but these devices are often complex in structure, high in cost, and have poor adaptability to specific types of egg products. Therefore, it is particularly important to develop an automatic egg product counting machine that is simple in structure, low in cost, highly adaptable, and capable of achieving accurate counting. SUMMARY

The design of the skirt plate effectively prevents the scattering of the material during conveying, reducing the risk of material waste and environmental pollution.

[0019] 2) Enhance the cleanliness of material conveying: The skirt plates on the skirt mesh belt pieces overlap each other, forming a closed conveying environment, effectively isolating external impurities from the material, ensuring the cleanliness of material conveying.

[0020] 3) Improve production efficiency: The driving device drives the continuous rotation of the circular conveying mesh belt, achieving automatic lifting and feeding of the material, greatly reducing the labor intensity and improving the production efficiency. At the same time, due to the continuous and stable conveying process, the production delay caused by material blockage or interruption is reduced.

[0021] 4) Effectively prevent material accumulation: By designing intermediate hoppers, primary and secondary vibrating feeders, and making the conveying surface height gradually decrease, a stepped conveying surface is formed, allowing the material to be dispersed step by-step during conveying, effectively avoiding the problem of material accumulation in traditional conveying methods. This design ensures the smoothness of material flow and reduces the risk of equipment downtime caused by accumulation.

[0022] 5) Improve material dispersion uniformity: The multi-stage vibrating conveying device disperses the material multiple times through the vibration of each vibrating feeder during conveying. This multiple dispersion mechanism allows the material to maintain high uniformity before reaching the final packaging stage, providing a more stable and reliable material basis for subsequent counting and packaging operations.

[0023] (6) Improve production efficiency: Through multi-channel design, this device can simultaneously process material counting in multiple channels, greatly improving the counting speed. Combined with the natural material falling method based on its own weight, it realizes a continuous operation process of counting and packaging simultaneously, effectively shortening the production cycle and improving the overall production efficiency.

[0024] (7) Enhance flexibility: The retractable upper and lower partitions and the discharge partition inside the device allow users to flexibly adjust the size of the counting and buffer chambers and the timing of material discharge according to different packaging specifications.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1-16 As shown, the present invention provides a technical solution:

[0046] An automatic egg product counting machine includes a frame 1, on which are sequentially connected a hoist 2, an intermediate feeding hopper 3, a primary vibrating conveyor 4, a secondary vibrating conveyor 5, a belt conveyor 6, and a dropping counting bin 7. The conveying surface heights of the intermediate feeding hopper, the primary vibrating conveyor 3, the secondary vibrating conveyor 4, and the belt conveyor 5 are progressively lower, and the intermediate feeding hopper, the primary vibrating conveyor 3, the secondary vibrating conveyor 4, and the belt conveyor 5 are connected end to end to form a stepped conveying surface. The discharge end of the belt conveyor is connected to the inlet of the dropping counting bin, and a packaging box conveyor is installed on the frame below the inlet of the dropping counting bin. The egg products are first lifted by the hoist into the intermediate feeding hopper, then vibrated by the primary and secondary vibrating conveyors, and then conveyed by the belt conveyor into the dropping counting bin for counting and packaging. Finally, they fall into the packaging boxes on the packaging box conveyor 8.

[0047] Regarding the design of the elevator section: the elevator 2 includes a ring conveyor belt 206 rotatably mounted on the frame. The ring conveyor belt is connected to a drive device, which includes a drive sprocket 208 and a driven sprocket 209 rotatably mounted on the frame. The drive sprocket and driven sprocket are installed at both ends of the ring conveyor belt and engage with the ring conveyor belt for transmission. The drive sprocket is connected to a drive motor. By using the drive sprocket and driven sprocket to engage with the ring conveyor belt for transmission, efficient transmission of driving force is achieved. This design not only ensures the smooth operation of the conveyor belt but also improves transmission efficiency and reduces energy loss. The annular conveyor belt includes multiple skirted mesh belt components 210 hinged end-to-end. Each skirted mesh belt component includes a mesh chain plate 211, with skirted plates 212 mounted upwards on both sides of the conveying surface. The skirted plates on the multiple skirted mesh belt components overlap each other. Scrapers 2213 are also evenly distributed and mounted upwards along the circumference of the annular conveyor belt. The scrapers, mesh chain plates, and skirted plates form a receiving and conveying trough. The discharge port of the hopper extends to the top of the scraper, which improves the discharge efficiency. Extending the discharge port of the hopper to the top of the scraper allows the material to fall directly into the hopper upon reaching the discharge port, without the need for additional conveying or transfer processes. This greatly improves the discharge efficiency and reduces the residence time of the material during the conveying process. At the same time, the above design can prevent material accumulation by utilizing the scraper and discharge port.

[0048] A feeding hopper 202 is installed on the frame 1 at the bottom of the lifting surface of the elevator 2. The lifting surface of the elevator is inclined. A discharging hopper 203 is installed on the frame at the top of the lifting surface of the elevator. The feeding hopper includes a hopper frame 204 installed on the elevator. A hopper section 205 is installed on the upper part of the hopper frame. The hopper opening of the hopper section decreases linearly from top to bottom. The special design of the hopper section can increase the material capacity and has the following design advantages: (1) Combination of hopper frame and hopper section: By setting a hopper frame on the elevator and configuring a hopper section on its upper part, the material can enter the elevator in an orderly manner. The linear decreasing design of the hopper opening helps the material to slide naturally to the conveying surface under the action of gravity, reducing blockage and material accumulation, and improving feeding efficiency; (2) Improve feeding uniformity: The decreasing design of the hopper opening can also make the material more evenly distributed when it falls into the conveyor belt, avoiding local overload, thereby extending the service life of the conveyor belt and reducing the problem of unstable conveying caused by uneven material distribution.

[0049] A support device is installed on the frame 1 at the lower center of the conveying surface of the annular conveyor belt. The support device includes a support rail 214 installed on the frame, which supports the inner wall of the annular conveyor belt. Multiple support rails are installed and arranged along the conveying direction of the annular conveyor belt. A support frame 215 is installed on the frame at the position corresponding to the support plate. A limit block 216 is installed on the support frame. A groove 217 that cooperates with the limit block is opened at the bottom of the support plate. The structural design of the above support device has the following advantages: (1) Function of the support rail: The support rail is set at the lower center of the conveying surface of the annular conveyor belt, which can effectively support the inner wall of the belt and prevent sagging or deformation caused by excessive belt length or material weight. This helps to maintain the smooth operation of the belt and improve the conveying efficiency. (2) Enhanced structural stability: By arranging multiple support rails along the conveying direction and fixing them with support frames and limit blocks, the structural stability of the entire conveying system can be further enhanced. The cooperation between the limit block and the slot ensures the accurate installation and stable positioning of the support rail.

[0050] Side pads 218 are installed on the frame 1 below the upper and lower conveying surfaces of the annular conveyor belt. The side pads 218 are detachably installed on both sides of the upper and lower conveying surfaces of the annular conveyor belt to protect the conveyor belt edges. The structural design of the side pads has the following advantages: (1) Setting side pads on both sides of the upper and lower conveying surfaces of the annular conveyor belt can effectively prevent materials from directly contacting the belt edges during conveying, reducing the risk of wear and tear. This is of great significance for extending the service life of the conveyor belt. (2) Easy maintenance and replacement: The detachable design of the side pads makes it more convenient and quick to replace or maintain them, reducing maintenance costs and time costs. At the same time, it is also convenient to adjust the material and size of the side pads according to actual needs to adapt to the conveying requirements of different materials.

[0051] After being lifted by the elevator, the material falls into the intermediate distribution hopper for subsequent vibratory conveying. The vibratory conveying section is designed as follows: the conveying surface heights of the intermediate distribution hopper 3, the primary vibratory conveying disc 4, the secondary vibratory conveying disc 5, and the belt conveyor 6 decrease sequentially. These components are connected end-to-end to form a stepped conveying surface. By designing multiple conveying links, including the intermediate distribution hopper, the primary vibratory conveying disc, and the secondary vibratory conveying disc, and forming a stepped conveying surface, the material is gradually dispersed during conveying, effectively avoiding the problem of material accumulation in traditional conveying methods. This design ensures smooth material flow and reduces the risk of equipment downtime due to accumulation.

[0052] The intermediate feeding hopper is equipped with a conical distribution plate 16 in its central part, which divides the hopper into multiple chambers 17. Each chamber 17 corresponds to a primary vibrating conveyor plate. This design allows materials entering the intermediate feeding hopper from the elevator or other feeding equipment to be first dispersed into the various chambers by the conical distribution plate, and then enter the corresponding primary vibrating conveyor plates. This chambered design not only helps to further disperse the material but also ensures the uniformity and stability of the material during the conveying process. At the same time, it also improves the equipment's processing capacity and flexibility, enabling the device to better adapt to different materials and packaging requirements.

[0053] Both the primary and secondary vibratory conveyor discs 4 and 5 include linear vibrators 15 mounted on the frame. Each linear vibrator is equipped with a vibrating conveyor trough. Specifically, the linear vibrator 15 can be an electromagnetic hopper linear vibrator: HD-ZL200. Linear vibrators are installed in both the primary and secondary vibratory conveyor discs, and vibrating conveyor troughs are provided. The linear vibrators generate stable linear vibration, which is highly effective for material dispersion and conveying. Through the transmission of the vibrating conveyor trough, the material is continuously subjected to uniform vibration during conveying, effectively preventing material accumulation and promoting uniform dispersion. This design not only improves the efficiency of material conveying but also ensures the accuracy of material counting and packaging in subsequent processes. The discharge end of the primary vibratory conveyor disc is equipped with a bending section 18, which overlaps with the inlet position of the primary vibratory conveyor disc 4, ensuring smooth entry of the items to be packaged from the primary to the secondary vibratory conveyor disc.

[0054] The secondary vibratory conveyor disc 5 is topped with a corrugated distribution plate 19, which separates and conveys the material from the primary vibratory conveyor disc. The discharge end of the corrugated distribution plate extends to a belt conveyor with multiple conveying channels, each corresponding to one channel at the end of the distribution plate. The application of the corrugated distribution plate in the secondary vibratory conveyor disc: This design cleverly utilizes the corrugated shape to guide the material, allowing it to be separated and conveyed from the primary vibratory conveyor disc. The corrugated distribution plate not only helps to further disperse the material but also ensures that the material remains orderly during conveying, reducing crossing and overlapping. Its discharge end extends directly to the belt conveyor, achieving a seamless connection between material dispersal and conveying.

[0055] Regarding the belt conveyor section, the belt conveyor includes a first belt conveyor 13 and a second belt conveyor 14 connected end to end. The conveying surface height of the first belt conveyor 13 is higher than that of the second belt conveyor 14. The double belt conveyor design has the following design advantages: (1) Improved material conveying efficiency: By using a first belt conveyor and a second belt conveyor connected end to end, and with the conveying surface height of the first belt conveyor being higher than that of the second belt conveyor, the material is decelerated step by step and conveyed stably. This design helps to reduce the jumping and scattering of materials during the conveying process, and improves the efficiency and stability of material conveying. (2) Adaptability to different material characteristics: The design of the double belt conveyor allows the device to be adjusted according to the characteristics of different materials and conveying requirements. For example, for fragile or easily deformable materials, the impact and damage of the material can be reduced by adjusting the drop and speed difference between the two belt conveyors.

[0056] Multiple partitions 20 are installed side-by-side above the conveying surface of the belt conveyor on the frame 1. The partitions are arranged along the conveying direction, and a conveying channel is formed between two partitions that corresponds one-to-one with the material dropping channel of the material counting bin. A gantry crane 9 is installed on the frame corresponding to the partition position. An adjustment groove 10 is opened on the gantry crane perpendicular to the conveying direction. An adjustment rod 11 is installed on the upper part of the partition corresponding to the adjustment groove position. A locking nut 12 is installed through the adjustment groove at the upper end of the adjustment rod. The spacing between the partitions can be changed by changing the position of the locking nut. The adjustable spacing partition design has the following design advantages: (1) Enhanced flexibility: By installing multiple partitions side-by-side above the conveying surface of the belt conveyor and setting adjustable spacing adjustment rods and locking nuts, the spacing between the partitions can be flexibly adjusted according to the size of different materials and packaging requirements. This design greatly enhances the adaptability and flexibility of the device and can meet various packaging specifications and production requirements. (2) Improved packaging accuracy: By accurately adjusting the spacing of the partitions, it can be ensured that the quantity of material in each conveying channel corresponds one-to-one with the material dropping channel, thereby improving the accuracy and precision of packaging. This is especially important for products that require precise control of material quantity, such as pharmaceuticals and food. (3) Simplified operation and maintenance: The design of the adjusting rod and locking nut makes adjusting the partition spacing simple and quick. Operators only need to rotate the locking nut to change the position of the adjusting rod in the adjusting groove, thereby adjusting the partition spacing. This design not only reduces the difficulty of operation, but also facilitates the daily maintenance and upkeep of the equipment.

[0057] The design of the seven-part material counting chamber includes: a material discharge port 301 at the top of the material counting chamber; multiple material discharge channels 302 installed side-by-side inside the material counting chamber; fiber optic sensors 303 installed on the frame corresponding to the material discharge port to detect the quantity of material entering each material discharge channel; retractable upper partitions 304 and lower partitions 305 installed on the frame corresponding to the positions within the material discharge channels, extending into the material counting chamber and dividing the material discharge channels into counting chambers 306 and buffer chambers 307; a main material discharge chamber 308 installed at the bottom of the material counting chamber, with a discharge port 309 at its bottom; and a retractable discharge partition 310 installed on the frame corresponding to the position of the discharge port. When the upper partition is in the extended position, the counting chamber and buffer chamber are isolated from each other; when the upper partition is in the retracted position, the counting chamber and buffer chamber are connected. When the partition is in the extended position, the buffer chamber and the main discharge chamber are isolated from each other. When the upper partition is in the retracted position, the buffer chamber and the main discharge chamber are connected to each other. By switching the working positions of the upper partition, lower partition, and discharge partition 310, processes such as discharge counting and batch discharge are realized. The counting process is as follows: In the initial state, the upper partition, lower partition, and discharge partition are in the extended position, isolating the counting chamber. Items (such as braised eggs) fall into the upper partition from the discharge port. As the quantity accumulates, when the number of items in the counting chamber reaches the required quantity, the upper partition retracts, and the items fall into the lower partition. The upper partition resets, and the counting chamber continues to count for the next time. According to the packaging specifications, an appropriate number of lower partitions are opened so that items from multiple buffer chambers fall into the main discharge chamber. Then the lower partitions reset and wait for the next discharge. Then the discharge partitions open, and the items fall into the packaging box below.

[0058] The material counting chamber includes a back plate 313 and a front panel 314. Multiple baffles 315 are installed between the back plate and the front panel, forming a material discharge channel. The front panel is transparent. The material counting chamber design combining the transparent front panel and baffles has the following design advantages: (1) Facilitates observation and monitoring: Using a transparent front panel as part of the material counting chamber allows operators to clearly observe the flow and counting status of materials in the chamber, facilitating timely detection and handling of abnormalities. (2) Optimizes structural layout: The material discharge channel formed between the back plate, the front panel, and the multiple baffles has a compact structure and reasonable layout. This design not only improves space utilization but also makes the material flow in the channel smoother and more orderly, reducing collisions and friction losses between materials. (3) Enhances equipment aesthetics: The use of a transparent front panel makes the entire device more aesthetically pleasing and meets the aesthetic requirements of modern industrial equipment. At the same time, the transparent front panel also facilitates the cleaning and maintenance of the equipment.

[0059] The upper partition, lower partition, and discharge partition are all L-shaped plates. A drive cylinder 311 is installed on the frame 1 at the back of the upper partition, lower partition, and discharge partition. The drive cylinder 311 drives the upper partition, lower partition, and discharge partition to reciprocate and extend into the discharge counting chamber. The L-shaped plate design combined with the drive cylinder has the following design advantages: (1) Enhanced structural stability: Using L-shaped plates as the upper partition, lower partition, and discharge partition not only increases the strength and rigidity of the partition, but also makes the partition more stable during the extension and retraction process, reducing the risk of misalignment or damage caused by vibration or impact. (2) Improved control accuracy: By driving the L-shaped plate to reciprocate and extend, the precise control of the partition position is achieved. This mechanical transmission method has the characteristics of fast response speed and accurate positioning, which can ensure that the partition is in place quickly when needed, meeting the precise control requirements in the production process. (3) Simplified maintenance: The drive cylinder is a power source with a simple structure and is easy to maintain. When it is necessary to replace or repair the partition, it can be easily done by simply operating the drive cylinder, which reduces the difficulty and cost of maintenance.

[0060] A sliding hopper 312 is installed on the frame 1 at the discharge port corresponding to the main discharge bin, and a packaging box conveyor 8 is installed on the frame at the discharge port corresponding to the sliding hopper. The combination of the sliding hopper and the packaging box conveyor has the following design advantages: (1) Improved material flowability: The design of the sliding hopper allows the material falling from the discharge port to slide smoothly into the packaging box, reducing the accumulation and blockage of materials during the transmission process and improving material flowability. (2) Automated packaging: When used in conjunction with the packaging box conveyor, an automated process from material counting to packaging box filling is realized. When the material in the counting chamber reaches the preset quantity, the upper partition extends without affecting the next stage of counting. At the same time, the packaging box conveyor sends the empty packaging box to the designated position, the discharge partition retracts, the discharge port opens to release the material into the packaging box, and the packaging process is completed. This automated packaging method not only improves production efficiency but also reduces the risk and cost of manual operation.
