Description

Technical Field

[0001] This application belongs to the technical field of automated poultry egg processing equipment, and particularly relates to a poultry egg grading and palletizing machine. Background Art

[0002] At present, with the continuous development of society, as a daily food for people, poultry eggs have gone through production and processing links from not being disinfected to paying attention to disinfection and hygiene, and from being bulk-packed without size separation to being uniformly packaged by weighing. In egg processing, the degree of automation is getting higher and higher, and the entire production line covers various links such as poultry egg cleaning, drying, disinfection, weighing, and palletizing and packaging.

[0003] In the palletizing and packaging link, in the existing technology, the palletizing mechanism generally places eggs into egg trays one by one through manual operation; manual operation increases unstable factors. Some poultry egg processing plants adopt automated palletizing and packaging, using an egg-gripping manipulator to automatically pick up and place poultry eggs. The egg-gripping manipulator has a low egg breakage rate, but the egg-gripping manipulator can only place poultry eggs individually, which increases the action frequency of the equipment, increases the labor time, and has low production efficiency; some automated palletizing and packaging equipment uses a negative pressure suction cup to suck multiple eggs at a time. Although the production efficiency is improved, the negative pressure suction cup is likely to cause egg breakage, and the suction cup is easily blocked and fails, resulting in high equipment operation costs.

[0004] Moreover, in the existing automated poultry egg production line, various processing links such as poultry egg cleaning, drying, disinfection, weighing, and palletizing and packaging are arranged in a linear production line or an L-shaped production line. The entire equipment occupies a large space and requires a large number of auxiliary production personnel. Summary of the Invention

The rotary conveying unit includes a mounting frame, a rotary conveying mechanism, and an egg gripping mechanism. The rotary conveying mechanism transports the eggs through a plurality of egg gripping mechanisms that move cyclically on a horizontal plane. Although a single egg gripping mechanism can only grip one egg, since each egg gripping mechanism rotates and moves cyclically on the horizontal plane, multiple eggs can be loaded and unloaded simultaneously, improving production efficiency. And because the form of egg transportation is rotary cyclic conveying on a horizontal plane, when transporting the same number of eggs, the overall length of this rotary conveying unit is less than half of the length of a straight-line production line, and the overall width is significantly less than that of an L-shaped production line. Furthermore, the floor area of the entire egg grading and tray-loading machine can be significantly reduced.

[0056] The automatic tray-loading unit, the egg tray conveying unit, and the full-tray collection and conveying unit are jointly used for the in-tray packaging of eggs. The automatic tray-loading unit is arranged to dock with the other end of the rotary conveying unit. The automatic tray-loading unit is arranged below the egg gripping mechanism at the outlet end of the rotary conveying unit. The eggs automatically fall into the automatic tray-loading unit by their own weight; the egg tray conveying unit is arranged to dock with the automatic tray-loading unit. The outlet end of the egg tray conveying unit is located below the automatic tray-loading unit. The eggs automatically fall into the egg trays by their own weight; the full-tray collection and conveying unit is arranged to dock with the outlet end of the egg tray conveying unit. The egg trays filled with eggs are conveyed out by the full-tray collection and conveying unit and enter the subsequent film covering and packaging processing link.

[0057] Compared with the prior art, the egg grading and tray-loading machine provided by the present invention uses rotary conveying in cooperation with an egg gripping mechanism to convey eggs, with high egg conveying efficiency and low egg breakage rate. And the rotary conveying can greatly reduce the floor area of the egg conveying line, making the internal structure of the egg grading and tray-loading machine more compact and the entire egg grading and tray-loading machine occupy less space.

[0084] To enable those skilled in the art in the technical field to which this application pertains to more clearly understand this application, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments.

[0085] In an embodiment of the present invention, a poultry egg grading and tray loading machine has a structure as shown in Figures 1 to 3 , and includes a poultry egg conveying unit A1, a rotary conveying unit A2, an automatic tray loading unit A3, an egg tray conveying unit A4, and a full tray collection and conveying unit A5. Among them: The poultry egg conveying unit A1 is used to convey the scattered poultry eggs in an orderly manner, and the poultry egg conveying direction is as shown by the arrow a in Figure 1 . The poultry egg conveying unit A1 is arranged to dock with one end of the rotary conveying unit A2; the rotary conveying unit A2 is used to rotate and convey the poultry eggs to the automatic tray loading unit A3, and the rotary conveying direction of the rotary conveying unit A2 is as shown by the arrow c in Figure 1 . The automatic tray loading unit A3 is arranged to dock with the other end of the rotary conveying unit A2, and the automatic tray loading unit A3 is arranged below the poultry egg gripper mechanism at the outlet end of the rotary conveying unit A2; the egg tray conveying unit A4 is used to automatically convey the egg trays, and the egg tray conveying direction is as shown by the arrow in Figure 1As shown by arrow b, the egg tray conveying unit A4 is arranged to dock with the automatic tray loading unit A3, and the outlet end of the egg tray conveying unit A4 is located below the automatic tray loading unit A3; the full-tray collection and conveying unit A5 is used to convey the egg trays filled with poultry eggs to the next process, and the conveying direction of the egg trays is as Figure 1 shown by arrow d, and the full-tray collection and conveying unit A5 is arranged to dock with the outlet end of the egg tray conveying unit A4.

[0086] Since the poultry egg conveying unit A1, the egg tray conveying unit A4, and the full-tray collection and conveying unit A5 all have a certain length, for the convenience of layout and reduction of the floor area of the equipment, the poultry egg conveying unit A1 can be arranged to be parallel to both the egg tray conveying unit A4 and the full-tray collection and conveying unit A5. Preferably, the poultry egg conveying unit A1, the egg tray conveying unit A4, and the full-tray collection and conveying unit A5 are all perpendicular to the length direction of the receiving rotary conveying unit A2. That is, the poultry egg conveying unit A1 is located at one end of the length direction of the rotary conveying unit A2, the egg tray conveying unit A4 and the full-tray collection and conveying unit A5 have coincident axes and are located at the other end of the length direction of the rotary conveying unit A2, and the egg tray conveying unit A4 and the full-tray collection and conveying unit A5 are respectively located on both sides of the width direction of the rotary conveying unit A2 (a part of the egg tray conveying unit A4 is located below the rotary conveying unit A2). The rotary conveying unit A2 is located at the center of the entire poultry egg grading and tray loading machine, and coordinates and docks with the other functional units, so that the poultry egg grading and tray loading machine operates orderly.

[0087] This poultry egg grading and tray loading machine can realize the fully automatic operation of transporting, transferring, and batch loading of poultry eggs. The structures of the various functional units of this poultry egg grading and tray loading machine will be described in detail below:

[0088] Refer to Figure 4 , the poultry egg conveying unit A1 includes a frame 100 and a poultry egg conveying and turning mechanism 200 installed on the frame 100. The function of the poultry egg conveying and turning mechanism 200 is to automatically adjust the large and small ends of the poultry eggs through mechanized operation, so that the small ends of the poultry eggs are arranged in the same direction, facilitating the processing of the poultry eggs in subsequent processing procedures, reducing the breakage rate of the poultry eggs, and being applicable to various occasions of commercial processing of poultry egg grading and packaging.

[0089] The frame 100 serves as the installation foundation of the poultry egg conveying and turning mechanism 200. The frame 100 only needs to meet the installation position requirements and installation structural strength of the poultry egg conveying and turning mechanism 200, and its specific structure is not limited in the present invention.

[0090] Refer to Figures 5A to 5F , specifically, in this embodiment, the poultry egg conveying and turning mechanism 200 includes more than 2 driving rollers 210, a main chain transmission mechanism 220, a turning chain transmission mechanism 230, and more than 2 guide rods 240.

[0091] The driving roller 210 is used to support the poultry eggs. More than two driving rollers 210 are arranged at intervals and in parallel along the conveying direction of the poultry eggs. The poultry eggs are placed on the driving roller 210 (for example, a plurality of egg-shaped holes are provided on the driving roller 210) or between two adjacent driving rollers 210 (for example, a plurality of concave areas are provided on the driving roller 210, and the opposite concave areas of two adjacent driving rollers 210 form egg-shaped holes). The specific number of the driving rollers 210 depends on the processing quantity of the poultry eggs.

[0092] The driving roller 210 is driven by the main chain transmission mechanism 220 to convey the poultry eggs supported by the driving roller 210 forward along the conveying direction of the poultry eggs. Specifically, the main chain transmission mechanism 220 adopts a chain transmission mechanism driven by a motor. A plurality of pin shafts are arranged on the main chain of the main chain transmission mechanism 220, and the driving roller 210 is sleeved on the pin shafts. When the sprocket rotates, the main chain rotates forward, driving the driving roller to move forward in a cyclic and reciprocating manner along the conveying direction of the poultry eggs.

[0093] In this embodiment, referring to Figure 5B , the main chain transmission mechanism 220 includes a main shaft 221, more than one intermediate shaft 228, a driven shaft and two main chains. The two main chains are used to connect the two ends of the driving roller 210, and the two main chains rotate forward synchronously under the drive of the main shaft 221, the intermediate shaft 228 and the driven shaft. Specifically, when in use, depending on the overall length of the poultry egg conveying and turning mechanism 200, a plurality of tensioning sprockets can also be installed on the frame 100.

[0094] Specifically, referring to Figure 5A and Figure 5D , in this embodiment, the main shaft 221 includes a main shaft rod 2211, and a first transmission sprocket 223 and two main chain sprockets 227 installed on the main shaft rod 2211. The two main chains are respectively meshed with the main chain sprockets 227 on the same side of them to drive the driving roller 210 to move.

[0095] Referring to Figure 5B , in this embodiment, the intermediate shaft 228 includes an intermediate shaft rod and two intermediate sprockets 229 installed on the intermediate shaft rod. The specific number of the intermediate shafts 228 depends on the overall length of the poultry egg conveying and turning mechanism 200; the driven shaft includes a driven shaft rod and two driven sprockets installed on the driven shaft rod; the two main chains are respectively meshed with the main chain sprockets 227, the intermediate sprockets 229 and the driven sprockets on both sides of the frame 100 to provide the driving force for driving each driving roller 210 to move forward.

[0096] Referring to Figure 5A and Figure 5E, in this embodiment, the turning chain drive mechanism includes a turning shaft 222, a turning driven shaft, and a turning chain. The turning shaft 222 includes a turning shaft rod 2221 and a second drive sprocket 224 mounted on the turning shaft rod 2221. The first drive sprocket 223 and the second drive sprocket 224 are connected by a drive chain to transmit the torque output by the motor. By connecting the first drive sprocket 223 and the second drive sprocket 224 with a drive chain, the torque of the main shaft can be transmitted to the turning shaft 222, and then the torque can be synchronously output to the turning chain drive mechanism 230. The turning driven shaft includes a turning driven shaft rod and a turning driven sprocket mounted on the turning driven shaft rod; the turning chain meshes with the turning sprocket and the turning driven sprocket, so that the running direction of the turning chain is the same as that of the chain of the main chain drive mechanism 220, and the rotational speed of the chain is the same.

[0097] The turning chain drive mechanism 230 and the guide rod 240 are jointly used for turning the eggs. The turning chain drive mechanism 230 is arranged below the drive drum 210, and the turning chain of the turning chain drive mechanism 230 contacts the cylindrical surface of the drive drum 210 located above it. The turning chain drive mechanism 230 is set to have the same running direction and the same rotational speed as the chain of the main chain drive mechanism 220, so that the drive drum 210 supported by the turning chain will only move with the main chain drive mechanism in the area where the turning chain drive mechanism 230 is arranged, and will not rotate itself.

[0098] Specifically, in this embodiment, the turning sprocket 231 of the turning chain drive mechanism 230 is also mounted on the turning shaft rod 2221, that is to say, the turning shaft 222 also serves as one of the sprocket shafts of the turning chain drive mechanism 230. The first drive sprocket 223, the second drive sprocket 224, the main chain sprocket 227, and the turning sprocket 231 are sprockets of the same model, with the number of teeth being 20, 15, 16, and 12 respectively. The transmission ratio of the main shaft 221 and the turning shaft 222 is (20 / 15)*(12 / 16) = 1, that is, the linear speeds of the main shaft chain and the turning chain are the same. As Figure 5F shown in (b) of the figure, the contact point B of the drive drum 210 is subjected to two equal and opposite forces, so the drive drum 210 will only move with the main chain drive mechanism 220 in the area covered by the turning chain drive mechanism 230, and will not rotate.

[0099] More than 2 guide rods 240 are spaced apart along the direction perpendicular to the conveying direction of the eggs. The specific number of the guide rods 240 depends on the egg packaging specifications. For example, if an egg tray with six rows is used, 7 guide rods 240 need to be set. The guide rods 240 are arranged above the drive drum 210 so as to form a guide channel 290 between more than 2 adjacent guide rods 240. The guide rods 240 do not contact the drive drum 210 to avoid affecting the rotation of the drive drum 210.

[0100] The guide rod 240 is a bent rod. The length and bending angle of the bent rod section 241 depend on the size of the poultry egg, and specific data are not limited in this invention. The bent rod section 241 of the guide rod 240 is opposite to the position of the turning chain drive mechanism 230, that is, the turning area ( Figure 5A the area shown as T in Figure 5A ) coincides with the layout area of the turning chain drive mechanism 230, as shown in

[0101] When the poultry egg is conveyed to the bent rod section 241 of the guide rod 240, it will turn under the guiding action of the bent rod section 241. During the conveying process of the poultry egg, the poultry egg that needs to turn will lean towards the side of the turning bend against the guide rod 240 and complete the turning in the turning area T. The poultry egg that does not need to turn will lean towards the other side of the guide rod 240 and will not turn at the bent rod section 241 in the turning area T.

[0102] Since the guide rod 240 is suspended above the driving roller 210, in this embodiment, there is more than 1 guide rod mounting plate 270 on the frame 100. The guide rod mounting plate 270 is arranged above the guide rod 240 and the driving roller 210, and the guide rods 240 are spaced and mounted on the guide rod mounting plate 270.

[0103] Specifically, 3 guide rod mounting plates 270 can be set in this poultry egg conveying and turning mechanism. The 3 guide rod mounting plates 270 are respectively located at the incoming material place in the covering area of the guiding chain drive mechanism 250, the incoming material place in the covering area of the turning chain drive mechanism 230, and the incoming material place in the covering area of the direction adjusting chain drive mechanism 260. At these three positions, the poultry eggs are likely to touch the guide rod 240 to improve the stability of the guide rod 240.

[0104] See Figure 5A and Figure 5B , the working process of the poultry egg conveying and turning mechanism 200 provided by the embodiment of this invention is as follows: The poultry eggs enter from the covering area of the guiding chain drive mechanism 250 along the conveying direction ( Figure 5B the direction shown by the arrow in

[0105] ). During the conveying process of the poultry eggs, the poultry eggs that need to turn will lean towards the side of the turning bend and against the guide rod 240, and complete the turning in the turning area T. The eggs that do not need to turn will lean towards the other side of the guide rod 240 and will not turn in the turning area T; The poultry eggs that have completed the turning after passing through the turning area T enter the covering area of the direction adjusting chain drive mechanism 260, and under the condition that the driving roller 210 rolls quickly, they quickly shift to the same side, making the poultry eggs arranged neatly and facilitating entry into the next working station.

[0106] To solve this problem, as a preferred embodiment, the egg conveying and turning mechanism 200 further includes a guiding chain transmission mechanism 250 installed on the frame 100. The guiding chain transmission mechanism 250 is arranged below the driving roller 210, and the guiding chain transmission mechanism 250 is located in the feeding direction of the turning chain transmission mechanism 230; the guiding chain of the guiding chain transmission mechanism 250 contacts the cylindrical surface of the driving roller 210 above it, and the running direction of the guiding chain transmission mechanism 250 is the same as that of the main chain transmission mechanism 220.

[0107] Specifically, referring to Figure 5A and Figure 5C , the guiding chain transmission mechanism 250 includes a mounting shaft 251 and a guiding chain; the mounting shaft 251 includes a shaft rod, as well as a driven sprocket 252 and guiding sprockets (two in number, not visible in the figure) mounted on the shaft rod. The guiding chain meshes with the guiding sprockets, and the two guiding sprockets at the other end are installed in the frame through a shaft, and the two guiding sprockets on the same side are connected and driven by a guiding chain.

[0108] A speed regulation sprocket 226 is also installed on the turning shaft 222. The speed regulation sprocket 226 and the second driving sprocket 224 are located at different ends of the turning shaft 222. The speed regulation sprocket 226 and the driven sprocket 252 are connected and driven by a speed regulation chain, and the composed chain transmission mechanism enables the guiding chain transmission mechanism 250 to rotate in the same direction as the main chain transmission mechanism 220.

[0109] To reduce the length of the coverage area of the guiding chain transmission mechanism 250 and reduce the size of the entire egg conveying and turning mechanism 200 in the egg conveying direction, it is necessary to increase the rotational speed of the driving roller 210 in the coverage area of the guiding chain transmission mechanism 250. To achieve this purpose, the tooth number ratio of the speed regulation sprocket 226 to the driven sprocket 252 is 2:1 to 6:1, preferably 4:1, that is, the speed regulation sprocket 226 (the driving wheel) and the driven sprocket 252 are connected and driven by a speed regulation chain, and the composed chain transmission mechanism is a speed increasing mechanism.

[0110] The contact point A of the driving roller 210 in the coverage area of the guiding chain transmission mechanism 250 is subjected to two reverse acting forces, but since the acting force of the guiding chain transmission mechanism 250 is much greater than that of the main chain transmission mechanism 220, as shown in (a) of Figure 5F , the driving roller 210 still rotates rapidly in this area. The setting of the guiding chain transmission mechanism 250 increases the rotational speed of the driving roller 210 in the coverage area of the guiding chain transmission mechanism 250, greatly reducing the equipment length requirement and ensuring that the eggs quickly approach the guiding rod 240.

[0111] After turning around, the eggs sometimes cannot be stably parked horizontally in the middle of the driving roller 210, and the eggs are not neatly arranged and are prone to breakage. To solve this problem, as a preferred embodiment, the egg conveying and turning mechanism 200 further includes an alignment chain drive mechanism 260 installed on the frame 100. The alignment chain drive mechanism 260 is arranged below the driving roller 210 and is located in the feeding direction of the turning chain drive mechanism 230. The alignment chain of the alignment chain drive mechanism 260 contacts the cylindrical surface of the driving roller 210 above it, and the running direction of the alignment chain drive mechanism 260 is opposite to the running direction of the main chain drive mechanism 220.

[0112] Specifically, referring to Figure 5A and Figure 5B , the alignment chain drive mechanism 260 includes a mounting shaft 261 and an alignment chain; the mounting shaft 261 includes a shaft rod, as well as a driven gear 262 and alignment sprockets (two in number, not visible in the figure) mounted on the shaft rod. The alignment chain meshes with the alignment sprockets, and the two alignment sprockets at the other end are mounted in the frame through a shaft, and the two alignment sprockets on the same side are connected and driven by the alignment chain.

[0113] A driving gear 225 is also installed on the turning shaft 222. The driving gear 225 and the second driving sprocket 224 are located at the same end of the turning shaft 222, and the driving gear 225 meshes with the driven gear 262. The meshing of the two gears makes the alignment chain drive mechanism 260 rotate in the opposite direction relative to the main chain drive mechanism 220. As a preferred embodiment. The transmission ratio of the driving gear 225 to the driven gear 262 is 1.

[0114] To reduce the length of the coverage area of the alignment chain drive mechanism 260 and reduce the size of the entire egg conveying and turning mechanism 200 in the egg conveying direction, it is necessary to increase the rotation speed of the driving roller 210 in the coverage area of the alignment chain drive mechanism 260. To achieve this purpose, the contact point C of the driving roller 210 in the coverage area of the alignment chain drive mechanism 260 is subjected to two co-directional acting forces, as Figure 5F shown in (c) of

[0115] As a preferred embodiment, referring to Figure 5A , two side plates 280 can also be provided in the egg conveying and turning mechanism 200. The two side plates 280 are arranged on both sides of the frame 100 to protect the eggs therein from falling due to accumulation or unstable movement.

[0116] With the improvement of processing technology, when dealing with a large number of poultry eggs, it is required to grade the poultry eggs and distinguish the obviously too large and / or obviously too small poultry eggs from the normally sized ones. To achieve this technical purpose, it is necessary to convey the poultry eggs forward in an orderly manner and weigh each poultry egg one by one.

[0117] Specifically, referring to Figure 1 and Figure 4 , as a preferred embodiment, in the poultry egg grading and palletizing machine of the present invention, the poultry egg conveying unit A1 further includes an ordering conveying mechanism 400 and a reverse weighing and conveying mechanism 500 installed on the frame 100. The poultry egg conveying and turning mechanism 200, the ordering conveying mechanism 400, and the reverse weighing and conveying mechanism 500 are sequentially arranged along the conveying direction of the poultry eggs ( Figure 1 the direction indicated by the arrow a in ). Among them, the ordering conveying mechanism 400 also has a turning function and can turn the poultry eggs that are not fully turned by the poultry egg conveying and turning mechanism 200 to ensure that the axes of the poultry eggs on the poultry egg conveying unit A1 are unified and the large and small head directions are the same; the reverse weighing and conveying mechanism 500 is used to weigh each poultry egg one by one to facilitate the grading and packaging operations.

[0118] Referring to Figure 4 , the ordering conveying mechanism 400 includes an ordering conveying chain drive mechanism installed on the frame 100 and more than 2 driving wheels driven by the ordering conveying chain drive mechanism. The ordering conveying mechanism 400 and the poultry egg conveying and turning mechanism 200 are driven by two sprockets of the same model and the same number of teeth, so that the ordering conveying chain drive mechanism (the poultry egg conveying direction is as Figure 4 the direction indicated by the arrow a2 in ) and the poultry egg conveying and turning mechanism 200 (the poultry egg conveying direction is as Figure 4 the direction indicated by the arrow a1 in ) have the same rotation direction and the same rotation speed.

[0119] The ordering conveying mechanism 400 can adopt any existing equipment with the function of turning and conveying poultry eggs, and the specific structure of the ordering conveying mechanism 400 is not limited in the present invention. For example, the ordering conveying mechanism 400 can adopt the ordering conveying device in the utility model application "A Poultry Egg Sorting and Transporting Machine" with the application number CN202020207820.9. The ordering conveying device drives multiple roller shafts to move forward along the poultry egg conveying direction through two chain drive mechanisms. An egg-shaped hole is formed between two rollers with opposite positions on adjacent two roller shafts to ensure the axial unity of the poultry eggs on the ordering conveying device (there is still a situation where the large and small heads are not consistent). By setting friction blocks and friction strips, the roller shafts vibrate. This vibration is a compound movement of the rotation and movement of the roller shafts. Through the cooperation between the roller shafts and the vibration of the roller shafts, the postures of the poultry eggs are adjusted to be consistent, facilitating subsequent sorting, transfer, and film covering operations. The specific structure of this ordering conveying device will not be elaborated here.

[0120] Referring toFigure 4 , the reverse weighing and conveying mechanism 500 includes a weighing device 510 mounted on the frame 100, a reverse weighing and conveying chain drive mechanism 520, and more than two round rods 530 driven by the reverse weighing and conveying chain drive mechanism. Specifically, in the reverse weighing and conveying mechanism 500, the reverse weighing and conveying chain drive mechanism 520 drives the round rod 530 to move. Both ends of the round rod 530 are respectively sleeved on the pins of the chain of the reverse weighing and conveying chain drive mechanism 520. The reverse weighing and conveying chain drive mechanism 520 and the sorting and conveying chain drive mechanism are driven by two identical gears to ensure that the reverse weighing and conveying chain drive mechanism 520 (the direction of egg transportation is as shown by the arrow a4 in Figure 4 ) rotates in the same speed in the opposite direction as the sorting and conveying chain drive mechanism (the direction of egg transportation is as shown by the arrow a2 in Figure 4 ).

[0121] In the reverse weighing and conveying mechanism 500, the gap between two adjacent round rods 530 is set to allow one egg to pass through. The round rod 530 located on the lower side is used to push the egg forward (the direction of egg transportation is as shown by the arrow a2 in Figure 4 ). The round rod only pushes the egg to roll forward and has no supporting effect on the egg. The eggs output from the sorting and conveying mechanism 400 enter the reverse weighing and conveying mechanism 500 through the gap between two adjacent round rods 530. The weighing device 510 is arranged below the round rod 530 located on the lower side. The weighing device 510 can adopt any existing weighable sensor, and the number of weighing sensors should be the same as the number of guiding channels 290 (the number of columns of egg trays). When the egg rolls past the weighing sensor, the weight of the egg can be obtained.

[0122] The rotary conveying unit A2 is used to rotate and convey the eggs to the automatic tray loading unit A3. Refer to Figure 2 and Figure 3 . The rotary conveying unit A2 includes a mounting frame 600, a rotary conveying mechanism 700 mounted on the mounting frame 600, and more than two egg gripper mechanisms 300 driven by the rotary conveying mechanism 700. The rotary conveying mechanism 700 is specifically a chain drive mechanism. The rotation of the chain on the horizontal plane can be realized through two horizontally arranged large sprockets (the rotation direction is as shown by the arrow c in Figure 1 ). By mounting the egg gripper mechanism 300 on the chain, the egg gripper mechanism 300 can rotate in a cycle on the horizontal plane to continuously transfer the eggs.

[0123] To further simplify the structure of the egg grading and tray loading machine, refer to Figure 6 . In this embodiment, the egg conveying unit A1 and the rotary conveying unit A2 are driven by the same power unit. The power unit includes a power motor and its driven power shaft. That is, the power shaft 710 of the rotary conveying mechanism 700 also serves as the power shaft of the egg conveying unit A1.

[0124] Specifically, refer to Figure 6 , the output shaft of the power motor (not visible in the figure) is connected to the power shaft 710 through a coupling. The structure of the power shaft 710 is as Figure 7 shown. An orthogonal helical gear 711 and two rotary conveyor sprockets 712 are sequentially arranged on the shaft rod of the power shaft 710. The two rotary conveyor sprockets 712 are engaged with a rotary conveyor chain, and are jointly used to drive the egg gripper mechanism 300 to rotate circularly on a horizontal plane. The orthogonal gear pair formed by the orthogonal helical gear 711 and another orthogonal helical gear converts the vertical torque of the power shaft 710 into a horizontal torque output, and this horizontal torque is transmitted to the egg conveying unit A1 through a power transmission chain drive mechanism 900, and drives the main chain drive mechanism 220 of the egg conveying unit A1 to rotate. According to actual needs, the power transmission chain drive mechanism 900 can be set as a speed-reducing chain drive mechanism. For example, the speed ratio of the driving sprocket and the driven sprocket of the power transmission chain drive mechanism 900 is 2:1, so as to realize the overall synchronous conveying of the egg conveying unit A1 and the rotary conveying unit A2.

[0125] The egg gripper mechanism 300 can directly adopt any existing egg-gripping manipulator, and the specific structure of the egg gripper mechanism 300 is not limited in the present invention. This embodiment provides a specific implementation manner of the egg gripper mechanism 300, which can efficiently grasp and move eggs. Refer to Figures 8A to 8H , the specific structure of the egg gripper mechanism 300 is as follows:

[0126] Refer to Figures 8A to 8C , the egg gripper mechanism 300 of this embodiment includes a mounting plate 310, an egg claw component 320, an egg clip component 330, a swing clip component 340, a driving tooth component 350 and a driven tooth component 360. The egg claw component 320 is rotatably mounted on the mounting plate 310, and the egg clip component 330, the swing clip component 340, the driving tooth component 350 and the driven tooth component 360 are respectively mounted on different parts of the egg claw component 320.

[0127] Among them:

[0128] The mounting plate 310 is used for connecting with the rotary conveying mechanism 700 on the one hand and for mounting the egg claw component 320 on the other hand. Two rows of mounting holes are provided on the mounting plate 310 and are respectively connected to two chains of the rotary conveying mechanism 700 through rivets. To facilitate the movement of the egg gripper mechanism 300, rollers are provided on the mounting plate 310, and a circle of chutes is provided at the corresponding position on the mounting frame 600 to ensure the stability of the movement of the egg gripper mechanism 300.

[0129] Refer to Figures 8A to 8C, the egg claw component 320 is rotatably mounted on the mounting plate 310 so that the egg claws 321 of the egg claw component 320 can be switched between a first position and a second position. Specifically, the first position can be set as the position when the egg claw component 320 is in a vertical state. In this state, the poultry eggs are placed horizontally, which is the state of transporting the poultry eggs; the second position is the position when the egg claw component 320 is in a horizontal state. In the second position state, the overall height of the poultry egg gripper mechanism 300 is shortened. In this state, the poultry eggs are placed vertically, which is the state of placing the poultry eggs. Of course, the first position and the second position can also be set as the positions when the egg claw component 320 is in other states, as long as the requirements for picking and placing the poultry eggs are met. The specific positions are not limited in the present invention.

[0130] See Figure 8D and Figure 8E , the egg claw component 320 includes a mounting body 322 and egg claws 321 that are fixedly connected, wherein the mounting body 322 is used to connect with the mounting plate 310. Specifically, in this embodiment, the egg claw component 320 is rotatably connected to the mounting plate 310 through a pin shaft 308. Pin holes 329 are formed in both the mounting body 322 and the mounting plate 310. The axis of the pin hole 329 is perpendicular to the plane where the mounting plate 310 is located, and perpendicular to (when the egg claws 321 are in the first position) or parallel to (when the egg claws 321 are in the second position) the plane where the egg claws 321 are located.

[0131] To achieve mechanized automatic operation, see Figures 8A to 8C , in this embodiment, the poultry egg gripper mechanism 300 further includes a swing rod 370 and a connecting rod 380. The swing rod 370 is rotatably mounted on the mounting plate 310. Two ends of the connecting rod 380 are respectively rotatably connected to the swing rod 370 and the mounting body 322. The mounting plate 310, the egg claw component 320, the swing rod 370, and the connecting rod 380 form a four-bar mechanism A to ensure the movement stability of the egg claw component 320. To facilitate triggering the swing rod 370, as a preferred embodiment, a touch rod 371 can be provided at the end of the swing rod 370. As Figure 8C shown, by touching the touch rod 371 with a human hand or an external object, the touch rod 371 drives the swing rod 370 to swing.

[0132] To achieve automatic reset of the egg claw component 320, see Figures 8A to 8C , in this embodiment, the poultry egg gripper mechanism 300 further includes a first compression spring sleeve rod 302 and a first compression spring 301 sleeved on the first compression spring sleeve rod 302. One end of the first compression spring sleeve rod 302 is movably arranged on the swing rod 370, and the other end is movably inserted into a mounting hole formed in the mounting plate 310. The first compression spring 301 is located between the swing rod 370 and the mounting plate 310 to provide the driving force for resetting the egg claw component 320. As a preferred implementation manner, a connecting rod mounting portion 326 is further provided on the mounting body 322, and the connecting rod 380 is rotatably connected to the connecting rod mounting portion 326.

[0133] As a preferred embodiment, refer to Figure 8E , a first limiting rod 327 for limiting the egg claw component 320 to the first position and a second limiting rod 328 for limiting the egg claw component 320 to the second position are further provided on the installation main body 322 to ensure the position accuracy of the egg claw component 320. Correspondingly, a first limiting position and a second limiting position are provided on the installation plate 310; when the egg claw component 320 is in the first position, the first limiting rod 327 contacts the installation plate 310 and is limited by the first limiting position; when the egg claw component 320 is in the second position, the second limiting rod 328 contacts the installation plate 310 and is limited by the second limiting position.

[0134] The installation main body 322 is further used for installing other components of the poultry egg grasping mechanism 300 (including but not limited to the egg clip component 330, the swinging clip component 340, the driving gear component 350, the driven gear component 360). For example, in this embodiment, an egg clip installation part 323, a swinging clip installation part 324, a driving gear installation part 325 and a driven gear installation part are provided on the installation main body 322, and then the egg clip component 330, the swinging clip component 340, the driving gear component 350 and the driven gear component 360 can be installed on the installation main body 322.

[0135] To optimize the overall structural layout of the poultry egg grasping mechanism 300, the connecting rod installation part 326 is coaxial with the swinging clip installation part 340, and the connecting rod 370 and the swinging clip component 340 are located on both sides of the installation plate 310.

[0136] The egg claw 321 is used for placing poultry eggs, and an egg hole is provided on the egg claw 321. When the poultry egg is placed on the egg claw 321, the ellipsoidal poultry egg is partially embedded in the egg hole to ensure the stability of the poultry egg. The specific structure of the egg claw 321 is not limited in the present invention. Refer to Figure 8E , specifically, in this embodiment, the egg claw 321 is an open elliptical ring, which is U-shaped as a whole, and the central hole of the open elliptical ring constitutes the egg hole.

[0137] Refer to Figures 8A to 8C , the egg clip component 330 is rotatably installed on the egg clip installation part 323 of the egg claw component 320. Refer to Figure 8F , the part 334 where the egg clip component 330 is connected to the egg claw component 320 is located in the middle of the egg clip component 330.

[0138] Specifically, refer to Figure 8F, the egg clip component 330 includes an egg clip connection part 332 and an egg clip 331 that are fixedly connected. The egg clip connection part 332 is rotatably connected to the egg clip installation part 323; the egg clip 331 is opposite to the egg claw 321, forming a poultry egg gripper 305. The egg claw component 320 cooperates with the egg clip component 330 to enable the poultry egg gripper 305 to switch between two states of open and closed. When the poultry egg gripper 305 is in the open state, eggs can be taken and placed. When the poultry egg gripper 305 is in the closed state, the poultry egg gripper 305 firmly grabs the poultry egg, and the poultry egg can be transferred.

[0139] The function of the egg clip 331 is to cooperate with the egg claw 321 to tightly hold the poultry egg (after the poultry egg is placed on the egg claw 321, it is easy to shake when encountering an external force), and to protect the poultry egg from falling. Specifically, in this embodiment, the egg clip 331 is arc-shaped, and its shape matches the surface curvature of the poultry egg.

[0140] See Figures 8A to 8C , the swing clip component 340 is rotatably installed on the swing clip installation part 324 of the egg claw component 320. A clamping position 341 is provided on the swing clip component 340. The main function of the swing clip component 340 is to clamp the driving gear component 350, thereby providing the rotational driving force for the driving gear component 350.

[0141] Specifically, see Figure 8G , in this embodiment, three cantilevers 343 are provided on the swing clip component 340. The clamping position 341 is arranged in one of the cantilevers and is specifically hook-shaped. The center of the three cantilevers 343 is the connecting part 342 between the swing clip component 340 and the egg claw component 320. When the swing clip component 340 rotates around the swing clip installation part 324, the clamping position 341 clamps the driving gear component 350 or disengages from the driving gear component 350; the other two cantilevers are used for limiting the swing clip component 340 to maintain the poultry egg gripper in the open state or the closed state and prevent the swing clip component 340 from overtraveling.

[0142] Specifically, see Figure 8A , in this embodiment, a second torsion spring 307 is provided on the swing clip component 340. The two acting ends of the second torsion spring 307 act on the swing clip component 340 and the installation main body 322 respectively, so that the swing clip component 340 can be toggled by an external force and automatically reset under the action of the second torsion spring 307.

[0143] See Figures 8A to 8C, the driving gear component 350 is rotatably mounted on the driving gear mounting portion 325 of the egg claw component 320, the driven gear component 360 is rotatably mounted on the driven gear mounting portion of the egg claw component 320, and the driven gear component 360 is connected to the egg clip connecting portion 332. The driving gear component 350 and the driven gear component 360 are intermediate transmission components for driving the egg clip component 330 to rotate relative to the egg claw component 320, so as to open or close the poultry egg gripper.

[0144] See Figure 8C and Figure 8D , the driving gear component 350 includes a driving gear portion 351 and a clamping point 352 fixedly connected. A first torsion spring 306 is arranged in the driving gear component 350. The two acting ends of the first torsion spring 306 act on the driving gear portion 351 and the mounting main body 322 respectively, so that the clamping point 352 can be switched between two position states of being clamped in the clamping position 341 and disengaging from the clamping position 341. Specifically, in this embodiment, the first torsion spring 306 is a torsion spring structure with hooks at both ends, and the hooks at both ends are respectively hung on the driving gear portion 351 and the locking rod 3241 of the mounting main body 322.

[0145] See Figure 8H , a driven gear portion 361 is arranged on the driven gear component 360, and the driven gear portion 361 meshes with the driving gear portion 351. Specifically, in this embodiment, the driven gear component 360 is a lever mechanism, and a fulcrum 363 of the lever is formed by sleeving the middle part on the driven gear mounting portion. The driven gear portion is arranged at one end of the driven gear component 360 to form a power end, and a sleeve 362 is arranged at the other end of the driven gear component 360 for realizing the connection with the egg clip connecting portion 332.

[0146] Specifically, in this embodiment, the driven gear component 360 is connected to the egg clip connecting portion 332 through a connecting component. See Figures 8A to 8C , the poultry egg gripper mechanism 300 further includes a second compression spring sleeve rod and a second compression spring sleeved on the second compression spring sleeve rod. One end of the connecting component is sleeved with the sleeve of the driven gear component 360, and a compression spring mounting hole is formed at the other end. A compression spring mounting hole 333 is also formed on the egg clip connecting portion 332. The second compression spring sleeve rod passes through the two compression spring mounting holes 333 and is locked by a pin. The connecting component is located between the second compression spring and the egg clip connecting portion 332, and the second compression spring provides a reset driving force for the egg clip component 330.

[0147] Thus, for the poultry egg gripper mechanism 300 provided in this embodiment, the horizontal or vertical state of the egg claw component 320 can be controlled through the swing rod 370, and the opening or closing state of the poultry egg gripper can be controlled through the swing clip component 340 and the driving gear component 350. The specific movement process of the poultry egg gripper mechanism 300 is as follows:

[0148] When the egg claw 321 of the egg claw component 320 is in the vertical position (the first position), the swing lever 370 is swung. Through the action of the four-bar linkage mechanism, the egg claw 321 flips. When the horizontal limit lever (the second limit lever 328) on the egg claw 321 touches the horizontal state limit surface (the second limit) of the mounting plate 310, the flipping action stops, and the egg claw 321 is in the horizontal state (the second position), as shown in Figure 9 ; Swing the swing lever 370 in the reverse direction. Through the action of the four-bar mechanism, the egg claw 321 flips. When the vertical limit lever (the first limit lever 327) on the egg claw 321 touches the vertical state limit surface (the first limit) of the mounting plate 310, the flipping action stops, and the gripper is in the vertical state (the first position), as shown in Figure 1 . When the position of the gripper changes to the end position (i.e., horizontal or vertical), under the action of the first compression spring 301, this state is maintained.

[0149] The swing clamp component 340 is in the initial position under the action of the second torsion spring 307 and the action of one of the cantilevers as a limit lever. The clamping position 341 of the swing clamp component 340 clamps the clamping point 352 of the driving gear component 350. Through the meshing of the teeth, the poultry egg gripper is in the closed state; when the swing clamp component 340 is rotated, the driving gear component 350 and the swing clamp component 340 open and disconnect. Under the action of the first torsion spring 306, the driving gear component 350 rotates, and through the gear mechanism, the poultry egg gripper is in the open state. The driving gear component 350 is toggled so that the clamping point 352 of the driving gear component 350 is engaged with the clamping position 341 of the swing clamp component 340, and the poultry egg gripper is in the closed state.

[0150] To enable the poultry egg gripper mechanism 300 to perform corresponding actions when moving to a specific position during the rotary conveying process. Refer to Figure 2 and Figure 3 . In this embodiment, the rotary conveying unit A2 further includes a gripper closing device 910, a vertical flipping guide rail 920, a kicking device 930, a gripper forced opening device 940, and a horizontal flipping guide rail 950. The gripper closing device 910, the vertical flipping guide rail 920, the kicking device 930, the gripper forced opening device 940, and the horizontal flipping guide rail 950 are sequentially installed on the mounting frame 600 along the rotation direction of the rotary conveying mechanism (as shown by the arrow c in Figure 1 ). Moreover, the gripper closing device 910 and the vertical flipping guide rail 920 are located on one side of the mounting frame 600, specifically on the side close to the poultry egg conveying unit A1 and the egg tray conveying unit A4; the kicking device 930, the gripper forced opening device 940, and the horizontal flipping guide rail 950 are located on the other side of the mounting frame, specifically on the side close to the automatic palletizing unit A3 and the full-tray collection and conveying unit A5; where:

[0151] Refer to Figure 2, the gripper closing device 910 is an inclined guide rod installed on the mounting frame 600. The installation position of the inclined guide rod is set to be opposite to the driving gear component 350 of the egg gripper mechanism 300. The inclined guide rod is inclined in the height direction of the mounting frame 600, and the high end of the inclined guide rod is close to the egg conveying unit A1.

[0152] In actual production, when the egg gripper mechanism 300 moves forward (the moving direction is as shown by the arrow c1 in Figure 1 ), the driving gear component 350 of the egg gripper mechanism 300 contacts the inclined guide rod. During the forward movement of the egg gripper mechanism 300, the driving gear component 350 rotates downward under the pressing action of the inclined guide rod (at this time, eggs have been placed on the egg gripper mechanism 300, so the gripper needs to be gradually closed) until the clamping point 352 of the driving gear component 350 is caught in the clamping position 341 of the swing clamp component 340. Through the action of the gear mechanism, the egg gripper mechanism 300 is changed from the state where the gripper is (horizontally) open (as shown by the state s1 in Figure 2 ) to the state where the gripper is (horizontally) closed (as shown by the state s2 in Figure 2 , and the egg claws 321 and the egg clip 331 clamp the eggs).

[0153] See Figure 2 and Figure 9 , the vertical turning guide rail 920 is inclined and installed on the mounting frame 600. The installation position of the vertical turning guide rail 920 is set to be opposite to the swing rod 370 of the egg gripper mechanism 300. The vertical turning guide rail 920 is inclined in the height direction of the mounting frame 600, and the low end of the vertical turning guide rail 920 is close to the egg conveying unit A1.

[0154] In actual production, when the egg gripper mechanism 300 moves forward (the moving direction is as shown by the arrow c1 in Figure 1 ), the swing rod 370 of the egg gripper mechanism 300 contacts the vertical turning guide rail 920. During the forward movement of the egg gripper mechanism 300, the swing rod 370 swings upward under the upward guiding action of the vertical turning guide rail 920. Through the action of the four-bar linkage mechanism ( Figure 8A marked as A), the egg gripper 305 of the egg gripper mechanism 300 is changed from the horizontal (closed) state (as shown by the state s2 in Figure 2 ) to the vertical (closed) state (as shown by the state s3 in Figure 2 ).

[0155] See Figure 3 and Figure 10, the egg kicking device 930 includes electromagnetic lever rods 931 that are the same in number as the number of rows of egg trays. The multiple electromagnetic lever rods 931 are installed on the mounting frame 600 through a bracket structure 934 and are located above the automatic tray loading unit A3. The electromagnetic lever rod 931 includes an electromagnet 933 and a lever rod 932 that can be adsorbed by the electromagnet 933. The installation position of the lever rod 932 is set to be opposite to the swinging clamp member 340 of the poultry egg gripping mechanism 300.

[0156] In actual production, when the poultry egg gripping mechanism 300 moves forward (the moving direction is as shown by the arrows c2 and c3 in Figure 1 ) to directly above the automatic tray loading unit A3, the electromagnet 933 is energized, and the lever rod 932 rotates under the attraction of the magnet (the rotating direction is as shown by the arrow e in Figure 10 ). During the rotation process, the lever rod 932 toggles the swinging clamp member 340, and the clamping position 341 of the swinging clamp member 340 disengages from the clamping point 352 of the driving tooth member 350. Through the action of the gear mechanism, the poultry egg gripping mechanism 300 changes from the gripping (vertical) closed state (as shown by the state s3 in Figure 3 ) to the gripping (vertical) open state (as shown by the state s4 in Figure 3 , the egg claws 321 and the egg clamps 331 are opened), and the poultry eggs grasped in the poultry egg gripper 305 automatically fall into the automatic tray loading unit A3, completing the egg placing operation.

[0157] See Figure 3 , the gripper forced opening device 940 is a rod installed on the mounting frame 600. The installation position of the gripper forced opening device 940 is set to be opposite to the swinging clamp member 340 of the poultry egg gripping mechanism 300.

[0158] In actual production, when the poultry egg gripping mechanism 300 moves forward (the moving direction is as shown by the arrow c3 in Figure 1 ), the swinging clamp member 340 of the poultry egg gripping mechanism 300 contacts the rod, and the rod forcibly toggles the swinging clamp member 340. The clamping position 341 of the swinging clamp member 340 disengages from the clamping point 352 of the driving tooth member 350. Through the action of the gear mechanism, the poultry egg gripping mechanism 300 is in the gripping (vertical) open state (as shown by the state s4 in Figure 3 , the egg claws 321 and the egg clamps 331 are opened).

[0159] The purpose of setting the gripper forced opening device 940 behind the egg kicking device 930 is to forcibly open all the poultry egg gripping mechanisms 300 passing through here, to avoid the situation where a certain poultry egg gripping mechanism 300 accidentally closes after egg placing, or the lever rod 932 fails to effectively toggle the swinging clamp member 340 during the egg placing operation resulting in no egg being placed, causing the poultry egg gripping mechanism 300 not to open during the egg loading operation and leading to poultry egg losses.

[0160] See Figure 3and Figure 11 The horizontally flipping guide rail 950 is inclinedly installed on the mounting frame 600. The installation position of the horizontally flipping guide rail 950 is set to be opposite to the swing rod 370 of the egg gripper mechanism 300. The horizontally flipping guide rail 950 is inclined in the height direction of the mounting frame 600, and the lower end of the horizontally flipping guide rail 950 is close to the egg conveying unit A1. The function of the horizontally flipping guide rail 950 is completely opposite to that of the vertically flipping guide rail 920. The horizontally flipping guide rail 950 and the vertically flipping guide rail 920 have the same structure, but are installed on different functional sides of the mounting frame 600 and have opposite inclination directions themselves.

[0161] In actual production, when the egg gripper mechanism 300 moves forward (the moving direction is as shown by the arrow c3 in Figure 1 ), the swing rod 370 of the egg gripper mechanism 300 contacts the horizontally flipping guide rail 950. During the forward movement of the egg gripper mechanism 300, the swing rod 370 swings downward under the downward guiding action of the horizontally flipping guide rail 950. Through the action of the four-bar linkage mechanism ( Figure 8A shown by the reference numeral A in Figure 3 ), the egg gripper 305 of the egg gripper mechanism 300 is changed from the vertical (open) state (as shown by the state s4 in Figure 3 ) to the horizontal (open) state (as shown by the state s5 in

[0162] ). This horizontal open state is the egg receiving state of the egg gripper mechanism 300. Figure 6 To ensure that eggs do not fall during the process from the reverse weighing and conveying mechanism 500 to the egg gripper mechanism 300, referring to

[0163] Specifically, referring to Figure 12A and Figure 12B the transition mechanism 800 includes a cam mechanism, a guide rail 820, a slider 830, a connecting rod 840, a guide member 850, and a transition support rod 860. The cam 810 of the cam mechanism is installed on the power shaft 710. Referring to Figure 13The cam 810 is a symmetrical structure, including two symmetrically arranged protrusions 811 and a symmetrically arranged recessed portion 812. The follower 870 of the cam mechanism is hinged to the mounting frame 600. The guide rail 820 is mounted on the mounting frame 600 in the horizontal direction. The slider 830 cooperates with the guide rail 820, and the slider 830 is rotatably connected to the follower 870. The guide member 850 is connected to the slider 830 through a connecting rod 840, and a guide groove 851 is provided on the guide member 850. The transition support rod 860 includes a support rod 861 and a bracket 862 fixed on the support rod 861 with the same number of egg trays. One end of the support rod 861 is rotatably mounted on the mounting frame 600, and the other end is embedded in the guide groove 851.

[0164] In actual production, the power shaft 710 rotates one circle, the cam mechanism generates two reciprocating motions, the follower 870 drives the slider mechanism to complete two cycles, and the transition support rod 860 completes the flipping of the eggs or flipping back to the original position during the relative sliding process with the guide member 850. In other embodiments, the guide member 850 can also be arranged to be fixedly mounted on the mounting frame 600, the transition support rod 860 is connected to the slider 830 through the connecting rod 840, and the transition support rod 860 is also provided with an extension portion extending into the guide groove 851, which can also realize the relative sliding of the transition support rod 860 and the guide member 850, thereby realizing the flipping of the transition support rod 860 to load the eggs or flipping back to the original position.

[0165] The automatic loading unit A3 is used to receive the eggs lowered from the egg gripper mechanism 300. Since the egg slot of the egg tray is relatively small, the egg gripper mechanism 300 still moves forward when it stands up during the egg placing operation. Therefore, the movement of the eggs after being lowered is a horizontal throwing movement. The automatic loading unit A3 acts as a buffer, accurately receiving the eggs lowered from the corresponding egg gripper mechanism 300, and then lowering the received eggs into the egg tray. The automatic loading unit A3 can use any existing egg cup device with a relatively large opening and an openable opening, such as the utility model patent "Automatic loading machine for eggs" with application number CN201820531973.1. The specific structure of the automatic loading unit A3 is not limited by the present invention.

[0166] Egg tray conveying unit A4 is used to automatically convey egg trays. The egg tray conveying direction is as follows: Figure 1 As shown by the middle arrow b, the egg tray conveying unit A4 can adopt any existing equipment that can transport egg trays, for example, the utility model patent "An egg tray delivery machine" with application number CN201922138144.4. The specific structure of the egg tray conveying unit A4 is not limited by the present invention.

[0167] The whole tray collection and conveying unit A5 is used to convey the egg trays filled with eggs to the next process. The egg tray conveying direction is as follows: Figure 1As shown by arrow d, the whole-tray collection and conveying unit A5 can adopt any existing conveying equipment as long as it meets the requirement of stable conveying. The specific structure of the whole-tray collection and conveying unit A5 is not limited in the present invention.

[0168] See Figures 1 to 3 , taking 6-row conveying as an example, the working process of the egg grading and tray-loading machine in this embodiment is as follows:

[0169] The egg conveying unit A1 conveys the scattered eggs in an orderly manner after turning the big and small ends and sorting. The egg conveying direction is as Figure 1 shown by arrow a in the figure. After being weighed by the reverse weighing and conveying mechanism 500, they are transported to the rotary conveying unit A2. At the same time, some of the egg gripper mechanisms 300 of the rotary conveying unit A2 are changed to the horizontal open state after forced opening and gripper direction-changing tracks, and run to the position opposite to the outlet end of the reverse weighing and conveying mechanism 500 to wait for receiving eggs.

[0170] The transition mechanism 800 controls the transition rod 860 to turn back to the egg-receiving position. The 6 eggs conveyed by the reverse weighing and conveying mechanism 500 fall into the 6 troughs 862 of the transition rod 860. The transition mechanism 800 controls the transition rod 860 to support the 6 eggs and turn and move along the guide groove 851. When the trough 862 turns, it just docks with the 6 horizontally opened egg gripper mechanisms 300 for turning and loading eggs. Then the transition mechanism 800 controls the transition rod 860 to turn back to the egg-receiving position for the next round of egg receiving.

[0171] The egg gripper mechanism 300 for gripping eggs becomes vertical after passing through the gripper direction-changing track. When it reaches the position of the egg-kicking device 930, according to the weighing data, the egg-kicking device 930 acts to open the corresponding 6 egg gripper mechanisms 300, and the eggs are horizontally thrown into the automatic tray-loading unit A3. After the automatic tray-loading unit A3 is filled with 6 eggs, the egg cup opens, and the eggs fall vertically into the egg tray by their own weight. After the egg tray is filled, it is conveyed by the whole-tray collection and conveying unit A5 to the subsequent process.

[0172] Through the above embodiments, the present invention has the following beneficial effects or advantages:

[0173] 1) The egg grading and tray-loading machine provided by the present invention uses rotary conveying in cooperation with the egg gripper mechanism to convey eggs, with high egg conveying efficiency and low egg breakage rate. Moreover, the rotary conveying can greatly reduce the floor area of the egg conveying line, making the internal structure of the egg grading and tray-loading machine more compact and the whole egg grading and tray-loading machine occupy less space.

[0174] 2) The egg grading and loading machine provided by the present invention is provided with an egg conveying and turning mechanism. The eggs are turned through the combined action of a turning chain drive mechanism and a guide rod. Due to the setting of the turning chain drive mechanism, the driving roller only moves and does not rotate itself in the area where the turning chain drive mechanism is arranged. When the eggs are conveyed to the bent rod section of the guide rod, they will turn due to the guiding action of the bent rod section. Through mechanized operation, the large and small ends of the eggs can be automatically adjusted, so that the small ends of the eggs are arranged in the same direction, improving the egg turning rate and reducing the egg breakage rate.

[0175] 2) The egg grading and loading machine provided by the present invention is provided with an egg conveying and turning mechanism. A guiding chain drive mechanism is arranged in the incoming material direction of the turning chain drive mechanism. In the turning area, the problem that eggs cannot approach the guide rod and affect the turning rate can be solved. And the setting of the guiding chain drive mechanism increases the rotation speed of the driving roller in the area where it is located, greatly reducing the equipment length requirement and ensuring that the eggs quickly approach the guide rod.

[0176] 3) The egg grading and loading machine provided by the present invention is provided with an egg conveying and turning mechanism. A direction-adjusting chain drive mechanism is arranged in the feeding direction of the turning chain drive mechanism, solving the problems that after turning, the eggs cannot be stably parked horizontally in the middle of the driving roller, the eggs are not neatly arranged and are easily damaged. And the setting of the direction-adjusting chain drive mechanism increases the rotation speed of the driving roller in the area where it is located, greatly reducing the equipment length requirement and ensuring that the eggs can reach the lying state smoothly and are neatly arranged.

[0177] 4) The egg grading and loading machine provided by the present invention uses an egg gripper mechanism to transfer eggs. The egg clip and the egg claw are positioned relative to each other to form an egg gripper. The egg claw component cooperates with the egg clip component to achieve egg grasping at the first position and egg placement at the second position. Different working states of the egg grading and loading machine are switched by a torsion spring, with stable working states, and can efficiently grasp and move eggs.

[0178] 5) The egg grading and loading machine provided by the present invention uses an egg gripper mechanism to transfer eggs. Different working positions of the egg gripper are maintained by a compression spring, facilitating the realization of mechanical automation. The egg gripper mechanism is composed of a specially shaped egg clip and an egg claw in cooperation, which can stably grasp eggs. The egg gripper mechanism is provided with a rotatable egg claw component, which can realize different egg grasping postures and transfer postures, facilitating the saving of the space occupied during the use of the device.

Therefore, the appended claims are intended to be construed as including the preferred embodiments as well as all changes and modifications falling within the scope of the present application.
