Description

Technical Field

[0001] This invention relates to the field of egg tray conveyor technology, and particularly to a conveyor line for feeding eggs onto egg trays. Background Technology

[0002] Egg tray loading is a key process in egg processing. Its core requirement is to accurately transport the egg trays to the designated loading station and ensure the structural integrity of the egg trays during transportation and positioning. At the same time, it is necessary to ensure the cleanliness of the egg tray placement troughs to provide a qualified carrier for subsequent egg loading, thereby improving loading efficiency and finished product qualification rate. Currently, existing egg tray loading conveyor lines have been gradually applied to large-scale production, but some technical defects still exist in actual operation.

[0003] In the egg tray conveying and positioning process, the positioning components of existing conveyor lines mostly adopt rigid positioning structures, which lack buffering and guiding functions. When there is a slight deviation in the initial placement position of the egg tray, it is impossible to achieve accurate position correction, which can easily lead to misalignment between the positioning components and the slots on the bottom of the egg tray. This not only affects the positioning efficiency, but may also damage the slots of the egg tray due to rigid impact. Summary of the Invention

[0004] The purpose of this invention is to provide a conveyor line for feeding eggs onto egg trays, which can ensure that the telescopic positioning component is accurately lifted and inserted into the groove on the bottom of the egg tray when it reaches the feeding station, thereby achieving accurate positioning of the egg tray and providing a guarantee for the feeding action of the egg tray feeding mechanism. This avoids the advantage of feeding deviation leading to egg breakage or misalignment of the egg tray.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conveyor line for feeding eggs onto egg trays, comprising a conveyor machine tool and a conveyor belt disposed thereon, wherein a plurality of positioning components are arranged around and at equal intervals on the conveyor belt; an egg tray feeding mechanism is mounted above one end of the conveyor machine tool;

[0006] The positioning assembly includes a mounting plate, a telescopic positioning component, a linkage component, an expansion component, and an air injection component. The telescopic positioning component is mounted on the mounting plate, and the telescopic positioning component has an expansion component connected to the air injection component on its outer surface. The conveyor belt is provided with a linkage component for driving the telescopic positioning component to extend and retract, and the mounting plate is mounted on the linkage component.

[0007] The telescopic positioning component includes a first conical component, a second conical component, a third conical component, and a connecting belt. The second conical component, the third conical component, and the third conical component are all connected by the connecting belt. When the first conical component and the second conical component retract, their top surfaces are flush with the top surface of the third conical component.

[0008] Below the egg tray feeding mechanism is the feeding station. When the telescopic positioning component passes the feeding station, it is driven by the linkage component to lift and insert into the groove on the bottom surface of the egg tray. At the same time, the expansion component expands under the air injection of the air injection component and comes into contact with the inner wall of the groove on the bottom surface of the egg tray. The telescopic positioning component moves with the conveyor belt and drives the egg tray to be conveyed.

[0009] Furthermore, the linkage component includes a linkage rod, a main drive gear, a linkage gear, a drive rod, and an ejector rod. The linkage rod is horizontally installed on the conveyor belt. A main drive gear is provided at one end of the linkage rod. Two linkage gears are symmetrically arranged on the linkage rod. The drive rod is connected to the bottom end of the mounting plate. A linkage rack that meshes with the linkage gear is provided on one side of the drive rod.

[0010] Furthermore, the conveyor belt is provided with a support plate for mounting the linkage rod, the ejector rod is fixed on the support plate, and the ejector rod penetrates the mounting plate and connects to the inside of the top of the first conical member.

[0011] Furthermore, the inner walls on both sides of the conveyor are provided with inner supports, and upper and lower racks that mesh with the main drive gear are respectively provided on the upper and lower ends of the inner supports. The upper and lower racks are staggered, and the upper rack is located at the feeding station.

[0012] Furthermore, the expansion member is composed of air rings, and there are three air rings, which are respectively fitted onto the first conical member, the second conical member and the third conical member, and ventilation grooves are opened in the connecting strip for the three air rings to communicate with each other.

[0013] Furthermore, the egg tray feeding mechanism includes a fixed bracket, a partition plate, a placement fork plate, and a driving component. The fixed bracket is fixed on both sides of the conveyor, the partition plate is placed horizontally between the fixed brackets, and the placement fork plate and the driving component are symmetrically arranged on the fixed brackets on both sides of the conveyor. The driving component is connected to the placement fork plate.

[0014] Furthermore, a support plate is provided in the middle of the conveyor belt, and several wedge-shaped blocks are elastically arranged on the support plate. The support plate is provided with slots for the wedge-shaped blocks to penetrate.

[0015] Furthermore, the conveyor is equipped with two material distribution devices, which are arranged side by side along the length of the conveyor.

[0016] Furthermore, the material distribution equipment includes an outer support, a movable support, an adsorption plate, a pressing and sealing sleeve, and an adsorption tube. The movable support is installed on the outer support, and the adsorption plate is installed on the movable support. Several pressing and sealing sleeves are arranged in an array below the adsorption plate, and an adsorption tube communicating with the several pressing and sealing sleeves is provided at the upper end of the adsorption plate.

[0017] Furthermore, the pressing and sealing sleeve is connected to the egg-laying groove at the top of the egg tray, and the pressing and sealing sleeve is sealed and pressed against the inner wall of the egg-laying groove.

[0018] The technical effects and advantages of this invention are as follows:

[0019] The first, second, and third conical components of this invention are all designed as conical structures. When the telescopic positioning component rises under the drive of the linkage component, the first conical component with the smallest top first enters the slot on the bottom surface of the egg tray. Even if there is a slight offset in the initial placement position of the egg tray, the inclined surface of the conical structure will form a guide slope. As the positioning component continues to rise, the conical surface will push the egg tray to make micro-motion corrections, guiding the egg tray to slide to the precise position until the third conical component is completely in contact with the inner wall of the slot. This ensures that the telescopic positioning component rises precisely when it reaches the feeding station and inserts into the slot on the bottom surface of the egg tray, achieving precise positioning of the egg tray. This provides a guarantee for the feeding action of the egg tray feeding mechanism and avoids feeding deviations that could cause egg breakage or misalignment of the egg tray.

[0037] 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.

[0038] Example 1: Refer to Figure 1 - Figure 11 The first embodiment of the present invention provides a conveyor line for placing eggs on egg trays, including a conveyor machine tool 1 and a conveyor belt 11 disposed thereon, wherein a plurality of positioning components 2 are arranged around and at equal intervals on the conveyor belt 11; an egg tray feeding mechanism 3 is mounted above one end of the conveyor machine tool 1.

[0039] The positioning component 2 includes a mounting plate 21, a telescopic positioning member 22, a linkage member 23, an expansion member 24, and an air injection member 25. The telescopic positioning member 22 is mounted on the mounting plate 21. The telescopic positioning member 22 has an expansion member 24 connected to the air injection member 25 on its outer surface. The conveyor belt 11 is provided with a linkage member 23 for driving the telescopic positioning member 22 to extend and retract, and the mounting plate 21 is mounted on the linkage member 23.

[0040] The telescopic positioning component 22 includes a first conical component 221, a second conical component 222, a third conical component 223, and a connecting belt 224. The second conical component 222, the third conical component 223, and the third conical component 223 are all connected by the connecting belt 224. The connecting belt 224 is made of a flexible material and connects the conical components at each level. The material of the connecting belt 224 can be rubber or high-elasticity polyurethane, etc. During the lifting process of the positioning component, when the first conical component 221 touches the bottom and is obstructed, the connecting belt 224 allows a small axial compression or offset between the conical components, which plays a mechanical buffering role, ensuring the final positioning stiffness, avoiding rigid impact at the moment of lifting, and effectively protecting the structural integrity of the egg tray.

[0041] The first conical component 221, the second conical component 222, and the third conical component 223 are all designed as conical structures. When the telescopic positioning component 22 rises under the drive of the linkage component 23, the first conical component 221 with the smallest top first enters the slot on the bottom surface of the egg tray. Even if there is a slight offset in the initial placement position of the egg tray, the inclined surface of the conical structure will form a guide slope. As the positioning component continues to rise, the conical surface will push the egg tray to make micro-movement corrections, guiding the egg tray to slide to the precise position until the third conical component 223 is completely in contact with the inner wall of the slot.

[0042] When the first conical component 221 and the second conical component 222 retract, their top surfaces are flush with the top surface of the third conical component 223. After the first conical component 221 and the second conical component 222 retract, the top surfaces of the three components form a continuous and flat support plane. The egg tray can slide freely before entering the feeding station. When the egg tray reaches the feeding station, the linkage component 23 triggers the lifting, and the telescopic positioning component 22 inserts into the insertion groove at the bottom of the egg tray. At this time, since the egg tray has been placed stably on the support surface, the position of the insertion groove is determined, and the insertion success rate is high.

[0043] Below the egg tray feeding mechanism 3 is the feeding station. When the telescopic positioning component 22 passes the feeding station, it is driven by the linkage component 23 to lift and insert into the groove on the bottom surface of the egg tray. At the same time, the expansion component 24 expands under the air injection of the air injection component 25 and comes into contact with the inner wall of the groove on the bottom surface of the egg tray. When the telescopic positioning component 22 moves with the conveyor belt 11, it drives the egg tray to be conveyed.

[0044] The linkage component 23 includes a linkage rod 231, a main drive gear 232, a linkage gear 233, a drive rod 234, and an ejector rod 235. The linkage rod 231 is horizontally installed on the conveyor belt 11. The main drive gear 232 is provided at one end of the linkage rod 231. Two linkage gears 233 are symmetrically arranged on the linkage rod 231. The drive rod 234 is connected to the bottom end of the mounting plate 21. A linkage rack 2341 that meshes with the linkage gear 233 is provided on one side of the drive rod 234. The linkage rod 231 drives the drive rod 234 to move up and down through the linkage gear 233 and the linkage rack 2341. When the drive rod 234 moves down, it causes the mounting plate 21 to move down synchronously. The ejector rod 235 is ejected, and the top end of the ejector rod 235 is installed with the top end of the inner groove of the first conical member 221. The mounting plate 21 moves down and is placed on the third conical member 223. It falls under the action of gravity. At the same time, the second conical member 222 also falls, realizing the lifting of the telescopic positioning component 22.

[0045] The linkage rod 231 is horizontally installed on the conveyor belt 11, realizing the synchronous drive of multiple telescopic positioning components 22 by a single linkage structure. This simplifies the drive structure and reduces the manufacturing cost and maintenance difficulty of the equipment. The main drive gear 232 set at one end of the linkage rod 231, together with two symmetrically arranged linkage gears 233, meshes with the linkage rack 2341 on one side of the drive rod 234. This smoothly converts the rotational motion of the linkage rod 231 into the up-and-down linear motion of the drive rod 234. The transmission accuracy is high and the stability is strong, ensuring that the lifting and retraction actions of the telescopic positioning components 22 are precise and controllable, avoiding positioning errors of the egg tray due to transmission deviation. The ejector rod 235 is fixed on the support plate and penetrates the mounting plate 21 and the first cone. The top of the shaped component 221 is internally connected, and when the mounting plate 21 moves down, the third conical component 223 and the second conical component 222 fall under the action of gravity, realizing the graded lifting of the telescopic positioning component 22. The action is smooth and continuous, further reducing the rigid impact on the egg tray. At the same time, the fixed setting of the ejector rod 235 can provide a limiting support for the first conical component 221, improving the structural stability of the telescopic positioning component 22 after lifting, preventing it from shifting, and ensuring positioning accuracy. In addition, the positioning component 2 moves synchronously with the conveyor belt 11, and several positioning components 2 are equidistantly set on the conveyor belt 11, realizing the continuity of egg tray conveying and positioning, greatly improving the production efficiency of eggs on egg trays, and meeting the needs of mass production.

[0046] The conveyor belt 11 is equipped with a support plate for mounting the linkage rod 231. The ejector rod 235 is fixed on the support plate and penetrates the mounting plate 21 to connect with the inside of the top of the first conical member 221. The support plate can provide stable mounting support for the linkage rod 231, preventing the linkage rod 231 from shaking or shifting during rotation, and ensuring the stability and accuracy of the linkage transmission. At the same time, the support plate can fix and limit the ejector rod 235, ensuring that the axial position of the ejector rod 235 remains unchanged, ensuring the reliability of the connection between the ejector rod 235 and the first conical member 221, thereby ensuring the smoothness of the lifting action of the telescopic positioning member 22, and preventing the telescopic positioning member 22 from tilting due to the offset of the ejector rod 235, which could damage the egg tray or affect the positioning effect. The positioning component 2 will move with the conveyor belt 11, and several positioning components 2 are equidistantly arranged on the conveyor belt 11.

[0047] The inner walls of both sides of the conveyor 1 are provided with inner supports 12. Upper racks 121 and lower racks 122, which mesh movably with the main drive gear 232, are respectively mounted on the upper and lower ends of the inner supports 12. The upper racks 121 and lower racks 122 are staggered. The upper rack 121 is positioned at the unloading station. The inner supports 12 provide a stable mounting surface for the upper racks 121 and lower racks 122, ensuring the flatness and firmness of the rack installation and guaranteeing the meshing accuracy with the main drive gear 232. The staggered arrangement of the upper racks 121 and lower racks 122 allows the main drive gear 232 to move along the conveyor belt 11. During the movement, it engages with the upper rack 121 and the lower rack 122 respectively, thereby driving the linkage rod 231 to rotate in both directions. This enables the telescopic positioning component 22 to lift at the feeding station and retract at non-feeding stations. No additional independent drive power source is required, saving equipment energy and simplifying control logic. The upper rack 121 is set at the feeding station, ensuring that the telescopic positioning component 22 is accurately lifted when it reaches the feeding station and inserted into the slot on the bottom of the egg tray, achieving accurate positioning of the egg tray. This provides a guarantee for the feeding action of the egg tray feeding mechanism 3 and avoids feeding deviation that could cause egg breakage or misalignment of the egg tray.

[0048] The expansion member 24 consists of three air rings, which are respectively fitted onto the first conical member 221, the second conical member 222, and the third conical member 223. The connecting strip 224 has ventilation grooves for interconnection between the three air rings. Each air ring corresponds to one of the three conical members. After the telescopic positioning member 22 is inserted into the slot on the bottom of the egg tray, air is injected through the air injection member 25, causing the three air rings to expand synchronously and fully contact the inner wall of the slot on the bottom of the egg tray. This significantly increases the contact area between the telescopic positioning member 22 and the egg tray, improving the stability of the positioning and preventing the egg tray from shifting or falling off due to vibration or shaking during transport. To ensure stable conveying, the ventilation grooves within the connecting belt 224 allow the three air rings to communicate with each other. This enables the three air rings to expand synchronously during air injection and contract synchronously during air release, ensuring a uniform distribution of expansion force. This prevents excessive local expansion from damaging the egg tray opening or insufficient local expansion from causing insecure positioning. It also simplifies the air injection pipeline structure, eliminating the need for separate air injection pipelines for each air ring, thus reducing the complexity of the equipment structure and manufacturing costs. Furthermore, the flexible expansion and fit of the air rings can accommodate minor dimensional errors in the egg tray opening, improving the adaptability of the equipment. At the same time, it avoids wear on the egg tray caused by rigid contact, protecting the structural integrity of the egg tray.

[0049] The egg tray feeding mechanism 3 includes a fixed bracket 31, a baffle plate 32, a placement fork plate 33, and a drive component 34. The fixed bracket 31 is fixed on both sides of the conveyor 1. The baffle plate 32 is placed horizontally between the fixed brackets 31. The placement fork plate 33 and the drive component 34 are symmetrically arranged on the fixed brackets 31 on both sides of the conveyor 1. The drive component 34 is connected to the placement fork plate 33. The baffle plate 32 is used to limit the egg tray after feeding. The egg tray will move with the conveyor belt 11 after feeding. When it moves to the baffle plate 32, which is also the feeding station, the upper side of the egg tray will be blocked by the baffle plate 32. When the telescopic positioning component 22 moves to align with the egg tray, the third cone 223 and the second cone 222 fall down. When the egg tray is inserted into the first cone 221, it also moves downward and releases the limiting relationship with the baffle plate 32.

[0050] Fixed brackets 31 are fixed on both sides of the conveyor 1, providing stable installation support for the baffle plate 32, the placement fork plate 33, and the drive component 34. This ensures the structural stability of the feeding mechanism and prevents shaking during feeding, which could affect feeding accuracy. The baffle plate 32 is horizontally placed between the fixed brackets 31, effectively limiting the egg tray after feeding and preventing it from shifting due to incomplete positioning in the initial feeding stage. This ensures that the egg tray is accurately aligned with the telescopic positioning component 22. The placement fork plate 33 and the drive component 34 are symmetrically arranged on both sides of the conveyor 1. The drive component 34 drives the placement fork plate 33 to move, enabling smooth feeding of the egg tray. The symmetrical structure ensures even force distribution during feeding, preventing... During the egg tray feeding process, the tray tilts and falls, while also allowing for easy adjustment of the spacing of the placement fork plates 33 according to the size of the egg tray, improving the adaptability of the equipment. When the egg tray moves to the baffle plate 32, the upper side of the egg tray is blocked by the baffle plate 32. At this time, the telescopic positioning component 22 moves to align with the egg tray, and the third cone component 223 and the second cone component 222 fall down. The egg tray is inserted into the first cone component 221 and moves downward, releasing the limiting relationship with the baffle plate 32. This realizes the linkage between egg tray feeding and positioning, ensuring that the egg tray can be quickly positioned after feeding, and the limiting release process is smooth, avoiding impact on the egg tray and further ensuring the structural integrity of the egg tray. At the same time, it improves the connection efficiency between feeding and positioning.

[0051] A support plate 13 is provided in the middle of the conveyor belt 11. Several wedge blocks 131 are elastically provided on the support plate 13. The support plate 13 has a slot for the wedge blocks 131 to penetrate. When the wedge block 131 is in a non-pressurized state, its top is flush with the top surface of the first cone 221, the second cone 222 and the third cone 223 when they are retracted. The wedge block 131 is located below the feeding station. When the egg tray is fed, its bottom is placed on the same horizontal plane formed by the wedge block 131 and the telescopic positioning member 22.

[0052] The support plate 13 provides installation support for the wedge block 131, while enhancing the load-bearing capacity of the conveyor belt 11, preventing deformation of the conveyor belt 11 due to the weight of the egg tray, and ensuring the conveying stability of the conveyor belt 11. The wedge block 131 is elastically set, and its top end is flush with the top surface of the telescopic positioning member 22 when it is in the retracted state under no pressure. It can form a flat support plane together with the telescopic positioning member 22, providing stable support for the egg tray unloading, preventing tilting and shaking of the egg tray due to uneven support surface during unloading, and ensuring that the egg tray can be placed stably. The wedge block 131 is located below the unloading station, and the bottom end of the egg tray rests on the support plane formed by the wedge block 131 and the telescopic positioning member 22 during unloading. The wedge block 131 can distribute the weight of the egg tray, reduce the load pressure on the telescopic positioning component 22, and extend the service life of the telescopic positioning component 22. At the same time, the elastic setting of the wedge block 131 can play a buffering role, absorbing the impact force when the egg tray is unloaded, and preventing the egg tray from being damaged by impact. In addition, the wedge block 131 can flexibly extend and retract through the slot, which can adapt to the lifting and retraction action of the telescopic positioning component 22 without affecting the normal operation of the positioning component 2, ensuring a smooth connection between the unloading and positioning actions. Since both sides of the wedge block 131 are inclined surfaces, when the positioning component 2 completes the alignment with the egg tray, it presses down on the inclined surface of the wedge block 131 when passing through it, causing the entire wedge block 131 to move down, without affecting the subsequent movement of the positioning component 2.

[0053] Two material distribution devices 4 are installed on the conveyor 1, arranged side by side along the length of the conveyor 1. Each material distribution device 4 includes an outer support 41, a movable support 42, an adsorption plate 43, a pressing sealing sleeve 44, and an adsorption tube 45. The movable support 42 is mounted on the outer support 41, and the adsorption plate 43 is mounted on the movable support 42. Several pressing sealing sleeves 44 are arranged in an array below the adsorption plate 43. An adsorption tube 45 communicating with the pressing sealing sleeves 44 is provided at the upper end of the adsorption plate 43. 44 is connected to the egg tray at the top of the egg tray, and the pressing and sealing sleeve 44 is pressed and sealed to the inner wall of the egg tray. The pressing and sealing sleeve 44 is used to seal the egg tray when it is pressed. The adsorption tube 45 is connected to the external adsorption system. When the pressing and sealing sleeve 44 is pressed and sealed to the egg tray, a negative pressure is generated inside it, which sucks away the impurities in the egg tray and holds the egg tray after the negative pressure is generated, and then transports it to the egg tray production line. By setting the positioning component 2, the position of the egg tray can be effectively determined to ensure that the pressing and sealing sleeve 44 can be pressed and sealed to the egg tray.

[0054] It is important to understand that two loader machines are arranged side by side on both sides of the conveyor machine 1 to load eggs into egg trays. The positioning component 2 and the egg tray unloading mechanism 3 can also be used on the two loader machines. When the sealing sleeve 44 is pressed and sealed against the inner wall of the egg tray, the external adsorption system of the adsorption tube 45 generates negative pressure, which can quickly suck away dust, debris and other impurities in the egg tray, ensuring the cleanliness of the egg tray unloading trough, avoiding the impact of impurities on the subsequent egg tray loading quality, and improving the qualification rate of the finished product. The negative pressure generated by the sealing and pressing can firmly adsorb the egg tray under the adsorption plate 43, preventing the egg tray from shifting or tipping due to conveyor belt vibration and external impact during the transfer and conveying process, ensuring that the egg tray can be accurately and stably transported to the designated work position of the loader machine. The material distribution device 4 is used for both impurity adsorption and egg tray transfer and conveying.
