Description

Technical Field

[0001] This application relates to the field of egg conveying equipment, and in particular to an egg pallet loading machine. Background Technology

[0002] After being cleaned and sorted, eggs need to be packed into egg trays for transportation, storage, and sale. When placing eggs in egg trays, they are usually loaded with the larger end up and the smaller end down. This allows the larger end, which contains the air cell, to have more contact with the atmosphere, reducing the chance of spoilage during storage and also preventing leakage if the eggs are damaged.

[0003] In existing related technologies, to ensure that eggs are placed into egg trays with the larger end facing up and the smaller end facing down, a turning device is usually used to turn the eggs around. For example, invention patent CN 112896594 A discloses a multi-row poultry egg packaging machine equipped with an egg turning device. This device uses a motor-driven mechanism to create a differential speed between the two ends of the egg, causing the eggs to be conveyed forward with the smaller end facing forward and the larger end facing backward. After the eggs are turned, they are further conveyed downward by a guide plate of the egg-laying device. The guide plate is driven by a sprocket and chain, allowing it to rotate vertically and continuously convey the eggs downward.

[0004] Regarding the aforementioned technologies, the egg product requires a motor to assist in turning, resulting in a complex structure that is inconvenient to maintain. Summary of the Invention

[0005] In order to simplify the structure of the egg loading machine and make it easier to maintain while ensuring the egg product turning effect, this application provides an egg loading machine.

[0006] The egg loading machine provided in this application adopts the following technical solution: An egg loading and unloading machine includes a frame, a middle turning assembly, an egg receiving assembly, and a loading and unloading turning assembly. The central turning assembly includes a central conveyor belt, a central partition, and a turning ramp. The central conveyor belt is used to transport horizontally placed eggs in a horizontal direction. Several central partitions are provided, and all of the central partitions are installed on the frame. The central partitions are distributed along the width direction of the central conveyor belt, and a central channel is formed between two adjacent central partitions. The width of the central channel is greater than the height of the eggs. The turning ramp is installed on the middle partition and is located at the output end of the middle conveyor belt. The turning ramp is provided with a turning ramp, which reduces the width of the middle channel along the conveying direction of the middle conveyor belt. The egg receiving assembly includes an egg receiving claw and a receiving conveyor belt. The egg receiving claw is used to receive eggs that fall after contacting the turning slope. The receiving conveyor belt is used to transport the egg receiving claw to the tray turning assembly in a rotary manner. The mounting and turning assembly includes a turning arc plate with an arc angle α greater than (5π) / 6. The top of the turning arc plate is located at the top of the receiving conveyor belt, and the bottom of the turning arc plate is located at the bottom of the receiving conveyor belt.

[0007] By employing the above technical solution, when the middle conveyor belt transports the eggs to the conveyor end, the eggs move at an angle towards their smaller end until they contact the turning ramp. Subsequently, the turning ramp obstructs the smaller end of the eggs, causing a gradual difference in speed between the two ends, resulting in the eggs falling into the receiving claws with their larger end facing down. After the eggs move with the receiving conveyor belt to the turning arc plate, the smaller end of the eggs flips and slides along the arc plate, thus ensuring that the eggs are fed into the egg tray with their smaller end facing down and their larger end facing up.

[0008] During the process of transporting eggs to the palletizing position by the central conveyor belt and the receiving conveyor belt, the eggs are gradually guided to complete the turning process by turning inclined blocks and turning arc plates in sequence. The impact on the eggs is small, reducing the use of drive components such as motors. This simplifies the structure of the palletizing machine while ensuring the turning effect of the eggs, making the palletizing machine easier to maintain.

[0009] Optionally, the central conveyor belt includes a central sprocket, a central chain, and central rollers. The central chain is wound around the central sprocket, and a plurality of central rollers are provided. The plurality of central rollers are distributed along the rotation path of the central chain, and a bearing gap is formed between two adjacent central rollers. The width of the bearing gap is smaller than the width of the egg. The turning ramp is provided in several parts, and each of the turning ramps corresponds to a central partition. Each turning ramp has two turning ramps, and the two turning ramps are located on both sides of the turning ramp.

[0010] By adopting the above technical solution, the load-bearing gap limits and transports the eggs, ensuring that the eggs remain horizontal during transport and are not easily deviated. This ensures that each egg contacts the turning slope in the expected posture and accurately completes the turning.

[0011] Optionally, the central conveyor belt further includes several egg push plates, all of which are mounted on the central sprocket. The egg push plates are circumferentially distributed around the axis of the central sprocket, and the egg push plates mesh with each central roller when rotating with the central sprocket. The egg push plates can extend into and pass through each bearing gap.

[0012] By adopting the above technical solution, as the eggs are about to fall from the output end of the central conveyor belt, the egg pusher plate lifts and pushes the eggs, causing the larger end of the egg to deflect forward first, making it easier for the egg to fall into the receiving claw with the larger end facing down. Furthermore, this increases the horizontal speed of the eggs, making it easier for them to detach from the central conveyor belt and reducing the likelihood of the eggs deflecting or skewing due to interference from the central rollers during the fall.

[0013] Optionally, the turning ramp is equipped with a flexible partition, and both the turning ramp and the flexible partition extend along the parabolic direction of the egg's fall.

[0014] By adopting the above technical solution, it is beneficial to maintain contact with the egg when the egg leaves the middle roller in a parabolic trajectory, ensuring that it can accurately turn around within a shorter drop height. This helps to reduce the occurrence of the egg being disturbed during the drop and not deflecting at the designed angle.

[0015] Furthermore, it also prevents two adjacent eggs from colliding due to opposite lateral velocities when falling simultaneously. For example, if the small ends of two adjacent eggs simultaneously contact a turning ramp and turn around through the ramp, the two eggs tend to move closer to each other laterally. The turning ramp and flexible partition, which extend along the parabolic trajectory of the eggs' fall, prevent the two eggs from being damaged by collision.

[0016] Optionally, the turning arc plate is provided in several parts, the spacing between two adjacent turning arc plates is adapted to the specifications of the egg tray, the several turning arc plates are divided into groups of two, and a turning gap is formed between the two turning arc plates in the same group. The width of the turning gap is adapted to the small end of the egg.

[0017] By adopting the above technical solution, when the eggs are turned around along the turning arc plate, the small end of the eggs is stuck into the turning gap, making it difficult for the eggs to shake during the turning process, thus ensuring that the eggs fall into the egg tray accurately in the correct posture according to the specifications of the egg tray.

[0018] Optionally, the mounting and turning assembly further includes an arc plate mounting rod, which is mounted on the frame and has a through-hole swing keyway. The top of the turning arc plate is rotatably fitted to the frame. The turning arc plate is equipped with an arc plate limiting post, which is swayably inserted through the swing keyway. The arc plate limiting post is fitted with a return spring, and the two ends of the return spring are respectively installed on the arc plate mounting rod and the turning arc plate.

[0019] By adopting the above technical solution, the turning plate can easily adapt to eggs of different sizes, and the eggs are less likely to collide with the turning plate, thereby reducing the occurrence of egg damage.

[0020] Optionally, the receiving conveyor belt includes a receiving sprocket and a receiving chain, the receiving chain is wound around the receiving sprocket, the receiving claw is installed on the receiving chain, and the rotation path of the receiving chain is provided with an inclined receiving section, the inclined receiving section is located at the bottom of the turning ramp, and the bottom of the inclined receiving section is set away from the turning ramp from bottom to top.

[0021] By adopting the above technical solution, when the eggs move to the inclined receiving section, the receiving claws face the turning ramp, making it easier for the eggs to fall accurately into the receiving claws. Especially when the eggs are pushed by the egg pusher plate, the horizontal speed at which the eggs leave the receiving section is faster, and the falling trajectory is straighter. The inclined receiving claws are more likely to align with the eggs, which helps to reduce the occurrence of eggs bouncing or shaking after entering the receiving claws. In addition, by setting up an inclined receiving section, it is also beneficial to stack the receiving conveyor belt and the middle conveyor belt in the vertical direction, thereby reducing the drop height of the eggs and reducing the occurrence of egg damage.

[0022] Optionally, the egg receiving assembly further includes a top guide rail and a bottom guide rail. The top guide rail is provided in a plurality of manner, and all of the top guide rails are mounted on the frame. The plurality of top guide rails are arranged to retract from the input end of the receiving conveyor belt toward the output end. The bottom guide rails are provided in a plurality of manner, and all of the bottom guide rails are mounted on the frame, and the bottom guide rails are arranged diverging from the output end of the receiving conveyor belt toward the input end. The receiving egg claws are provided in several rows, and the rows of receiving egg claws are distributed along the rotation direction of the receiving chain. The receiving egg claws in the same row are distributed along the width direction of the frame. The receiving egg claws slide and engage with the receiving chain. The receiving egg claws are provided with egg claw guide posts, and the egg claw guide posts slide and engage with the top guide rail and the bottom guide rail in sequence.

[0023] By adopting the above technical solution, the eggs are first turned around horizontally in the wider central channel, then turned around vertically through the turning arc plate for a second turn, and finally placed into egg trays with smaller spacing between the eggs. The egg claws, which gather and disperse along the top and bottom guide rails, ensure that the eggs are accurately placed into the smaller egg trays while effectively and accurately turning them around, thus reducing material waste in the egg trays.

[0024] Optionally, the frame is equipped with a feeding conveyor belt for conveying egg products; The egg loading machine also includes an egg diversion component, which includes a diversion baffle, a diversion rubbing plate, and a diversion motor. The diversion baffle is installed on the frame, the diversion rubbing plate slides horizontally in cooperation with the diversion baffle, and the diversion motor drives the diversion baffle to perform reciprocating sliding motion.

[0025] By adopting the above technical solution, it is easy to push the eggs in the opposite direction through the diversion baffle, reducing the occurrence of egg blockage caused by the eggs being blocked by the diversion baffle and becoming still.

[0026] Optionally, the flow divider is provided with a swing wheel groove, and the flow divider motor is equipped with an eccentric swing wheel. The axis of the eccentric swing wheel is offset from the axis of the output shaft of the flow divider motor, and the eccentric swing wheel slides and engages with the swing wheel groove.

[0027] By adopting the above technical solution, the eccentric balance wheel revolves around the output shaft of the shunt motor, and then drives the shunt scouring plate to reciprocate through the inner wall of the balance wheel groove, thereby realizing the reciprocating sliding motion of the shunt scouring plate with a compact and durable structure.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. When the middle conveyor belt transports the eggs to the conveyor end, the eggs move at an angle towards the smaller end until they contact the turning ramp. The turning ramp then blocks the smaller end of the eggs, causing a gradual difference in speed between the two ends, resulting in the eggs falling into the receiving claw with the larger end facing down. After moving with the receiving conveyor belt to the turning arc plate, the smaller end of the eggs flips and slides along the arc plate, thus being fed into the egg tray with the smaller end facing down and the larger end facing up. During the process of transporting eggs to the palletizing position by the central conveyor belt and the receiving conveyor belt, the eggs are gradually guided to complete the turning process by turning inclined blocks and turning arc plates in sequence. The impact on the eggs is small, reducing the use of drive components such as motors. This simplifies the structure of the palletizing machine while ensuring the turning effect of the eggs, making the palletizing machine easier to maintain.

[0029] 2. It helps maintain contact with the egg as it leaves the central roller in a parabolic trajectory, ensuring that it accurately turns around within a shorter drop height. This helps reduce the chance of the egg being disturbed during the drop and not turning at the designed angle. Furthermore, it also prevents two adjacent eggs from colliding due to opposite lateral velocities when falling simultaneously. For example, if the small ends of two adjacent eggs simultaneously contact a turning ramp and turn around through the ramp, the two eggs tend to move closer to each other laterally. The turning ramp and flexible partition extending along the parabolic trajectory of the eggs' fall prevent the two eggs from being damaged by collision. 3. When the eggs are turned around along the turning arc plate, the small end of the eggs is inserted into the turning gap, so that the eggs are not easy to shake during the turning process, thus ensuring that the eggs fall into the egg tray accurately according to the specifications of the egg tray in the correct posture. 4. When eggs move to the inclined receiving section, the receiving claws face the turning ramp, making it easier for the eggs to fall accurately into the receiving claws. Especially when the eggs are pushed by the egg pusher plate, the horizontal speed at which the eggs leave the container is faster, and the falling trajectory is straighter. The inclined receiving claws are more likely to align with the eggs, which helps to reduce the occurrence of eggs bouncing or shaking after entering the receiving claws. In addition, by setting up an inclined receiving section, it is also possible to overlap the receiving conveyor belt and the middle conveyor belt in the vertical direction, thereby reducing the drop height of the eggs and reducing the occurrence of egg damage.

[0042] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0043] This application discloses an egg loading machine. (See also...) Figure 1 and Figure 2 The egg loading machine includes a frame, an egg diversion component 1, a middle turning component 2, an egg receiving component 3, and a loading and turning component 4.

[0044] Reference Figure 3 The frame is equipped with a feed conveyor belt 5, which is used for horizontal linear conveying of eggs. The bearing surface of the feed conveyor belt 5 is set flat to facilitate the conveying of a large number of eggs that are close together, thereby ensuring the conveying efficiency of the feed conveyor belt 5. Furthermore, the flat bearing surface makes it easier for the eggs to shift towards the smaller end when rolling horizontally. In this application, the type of feed conveyor belt 5 is a sprocket-driven mesh chain conveyor belt.

[0045] A V-shaped guide plate 51 is provided at the top of the feeding conveyor belt 5. The V-shaped guide plate 51 is located in the middle of the width direction of the feeding conveyor belt 5. The V-shaped guide plate 51 is fixedly installed on the frame by mounting crossbars. The mounting crossbars are arranged along the width direction of the feeding conveyor belt 5, and both ends of the mounting crossbars are fixedly installed on the frame. The bottom of the V-shaped guide plate 51 is close to the bearing surface of the feeding conveyor belt 5, and the pointed end of the V-shaped guide plate 51 faces the direction of egg arrival. This facilitates the diversion of the eggs carried and conveyed by the feeding conveyor belt 5 to both sides of the V-shaped guide plate 51, thereby making the rear of the V-shaped guide plate 51 have a lower egg density than its sides. This makes it easier for the eggs to move to the rear of the V-shaped guide plate 51 under the action of the egg diversion component 1, and reduces the occurrence of eggs blocking the front of the egg diversion component 1.

[0046] In addition, the frame is equipped with two rotating detection plates 52, both located behind the mounting crossbar and on either side of the feed conveyor belt 5. When eggs become heavily congested in front of the egg diversion assembly 1, the eggs gradually accumulate and eventually squeeze and push the detection plates 52, causing them to rotate. The detection plates 52 are electrically connected to the control module of the egg loading machine. When the detection plates 52 rotate, the control module stops the eggs from being fed onto the feed conveyor belt 5 until the feed conveyor belt 5 clears the accumulated eggs and the detection plates 52 return to their original position, thereby further reducing the occurrence of eggs blocking the egg diversion assembly 1.

[0047] Reference Figure 3 The egg product diversion component 1 is located behind the detection turntable 52 and is used to divide the eggs that are being transported randomly by the feeding conveyor belt 5 into several columns for transport. Combined with... Figure 4 The egg diversion assembly 1 includes a diversion baffle 11, a diversion rubbing plate 12, an eccentric swing wheel 13, and a diversion motor 14. There are several diversion baffles 11, diversion rubbing plates 12, and eccentric swing wheels 13. The several diversion baffles 11, diversion rubbing plates 12, and eccentric swing wheels 13 correspond one-to-one, and the several diversion baffles 11, diversion rubbing plates 12, and eccentric swing wheels 13 are equidistantly distributed along the width direction of the feeding conveyor belt 5.

[0048] Reference Figure 4The top of the diversion baffle 11 is fixedly installed on the frame, and the bottom of the diversion baffle 11 is close to and fitted with the feeding conveyor belt 5, making it easier for eggs that are offset towards the smaller end to fit into the diversion baffle 11 with their smaller end. The diversion baffle 11 is assembled from two plates and a partition between the two plates, so that a groove is formed in the middle of the diversion baffle 11, and the extension direction of the groove is parallel to the conveying direction of the feeding conveyor belt 5. The diversion scooping plate 12 is arranged in an "L" shape, and the bottom of the diversion scooping plate 12 is close to the feeding conveyor belt 5. The top of the diversion scooping plate 12 slides and fits into the frame along the conveying direction of the feeding conveyor belt 5 through a slider and a slide rail, and the bottom of the diversion scooping plate 12 slides and fits into the diversion baffle 11 through the groove in the middle of the diversion baffle 11, so as to push the eggs in the opposite direction by the diversion scooping plate 12, reducing the situation where the eggs stop due to being blocked by the diversion baffle 11 and thus causing egg blockage.

[0049] The top of the diversion plate 12 is provided with a swing wheel groove 121, which extends vertically. An eccentric swing wheel 13, corresponding to the diversion swing wheel, is located inside the swing wheel groove 121 and slides within it. The diversion swing wheel 14 is fixedly mounted on the frame, and its output shaft is coaxially fixedly mounted with a swing wheel drive shaft. Several eccentric swing wheels 13 are eccentrically fixedly mounted on the swing drive shaft. Furthermore, the axes of two adjacent eccentric swing wheels 13 are located on opposite sides of the swing wheel drive shaft. This allows the two adjacent diversion plates 12 to move back and forth more significantly when the swing wheel drive shaft rotates, thereby pushing and agitating the eggs stationary in front of the diversion partition 11. This causes the eggs to move towards and redistribute to the lower-density area behind the V-shaped diversion plate, reducing the likelihood of eggs becoming stationary due to obstruction by the diversion partition 11 and causing blockages.

[0050] As the eggs roll through the egg distribution component 1, they tend to gravitate towards the smaller end as they roll laterally, making it easier for the smaller end to come into contact with the distribution baffle 11. After leaving the egg distribution component 1, the eggs will travel along multiple paths into the central turning component 2.

[0051] Reference Figure 5 and Figure 6The central turning assembly 2 includes a central conveyor belt and an egg pusher plate 21. The central conveyor belt is used to transport horizontally placed eggs in a horizontal direction. Specifically, the central conveyor belt includes central sprockets 22, central chains 23, and central rollers 24. There are four central sprockets 22, all of which are rotatably coupled to the frame. The four central sprockets 22 are divided into two groups, which are distributed on both sides of the frame along the width direction. The central sprockets 22 are driven by a motor (not shown in the figure). There are two central chains 23, which are respectively arranged corresponding to the two groups of central sprockets 22. One central chain 23 is wound around the two central sprockets 22 in the same group to facilitate the rotation of the central chain 23 by the motor and the central sprockets 22.

[0052] Several central rollers 24 are provided, distributed along the rotation path of the central chain 23, and arranged along the width direction of the frame. The two ends of each central roller 24 are rotatably engaged with two central chains 23, and a bearing gap 241 is formed between two adjacent central rollers 24. The width of the bearing gap 241 is smaller than the width of the egg, so that the egg can be placed horizontally within the bearing gap 241, allowing the egg to move along the rotation path of the central chain 23 following the central rollers 24.

[0053] Reference Figure 6 Several egg pusher plates 21 are provided, and these plates are coaxially fixed to the central sprocket 22 via a central axis. The egg pusher plates 21 are circumferentially distributed around the central axis, and engage with the central rollers 24 as they rotate with the central sprocket 22. This allows the egg pusher plates 21 to sequentially extend into and pass through the bearing gaps 241, thereby lifting and deflecting the eggs and pushing them away from the central rollers 24 at a higher speed, reducing the likelihood of collisions between the eggs and the central rollers 24. Furthermore, the egg pusher plates 21 are flat and plate-shaped. When the egg pusher plates 21 push the horizontally placed eggs, the eggs will sway horizontally, causing them to shift towards the smaller end, with the smaller end facing backward and the larger end facing forward. This makes it easier for the eggs to fall from the end of the central conveyor belt with the larger end facing down.

[0054] Reference Figure 5 The middle turning assembly 2 also includes a middle partition 25 and a turning ramp 26. Several middle partitions 25 are provided, which are distributed along the width direction of the frame. The middle partitions 25 are respectively arranged corresponding to each diversion partition 11, and the extension direction of the middle partitions 25 is consistent with the extension direction of the diversion partition 11, so that the eggs can be close to the corresponding diversion partition 11 after leaving the diversion partition 11.

[0055] Reference Figure 7 and Figure 8A central channel 251 is formed between two adjacent central partitions 25. The width of the central channel 251 is greater than the height of the eggs. This facilitates the horizontal transport of the eggs along the central channel 251. Furthermore, the disturbance caused by the central rollers 24 during transport causes the eggs to deflect towards the smaller end and approach the diversion partition 11, thus ensuring a higher success rate for subsequent turning. The number of turning ramps 26 is the same as the number of central partitions 25, and several turning ramps 26 are fixedly installed at the ends of each central partition 25. The turning ramp 26 has two turning ramps 261, which are located on both sides of the turning ramp 26. The turning ramps 261 cause the width of the central channel 251 to gradually decrease along the conveying direction of the central conveyor belt, so as to reduce the impact on the eggs. In addition, when the eggs are pushed off the central roller 24 in a parabolic trajectory by the egg pusher 21, the roller maintains contact with the eggs, ensuring that the eggs can accurately turn around within a short drop height. This helps to reduce the occurrence of the eggs being disturbed during the drop and not deflecting at the designed angle.

[0056] Reference Figure 8 When the small end of the egg is attached to the middle partition 25 and is conveyed forward by the middle conveyor belt to the position of the turning ramp 26, the small end of the egg will come into contact with the turning ramp 261, causing the small end of the egg to be resisted. This causes a speed difference between the large end and the small end of the egg, so that the large end of the egg that is not obstructed gradually moves forward while the small end that is obstructed gradually moves backward, thus completing the turning of the egg.

[0057] Reference Figure 7 Two flexible partitions 262 are fixedly installed on the turning ramp 261, located on either side of the turning ramp 261. The flexible partitions 262 extend along the parabolic trajectory of the falling eggs, making it less likely for two adjacent eggs to collide after being pushed away from the central roller 24 by the egg pusher 21. This helps reduce the adverse effects of the lateral velocity biased towards the smaller end of the eggs during fall. The flexible partitions 262 are made of flexible materials, such as rubber or silicone.

[0058] Reference Figure 9 The egg receiving assembly 3 includes egg receiving claws 31 and a receiving conveyor belt for rotating and conveying the egg receiving claws 31. The receiving conveyor belt includes receiving sprockets 32 and receiving chains 33. Several receiving sprockets 32 are provided, each rotatably engaged with the frame. The receiving sprockets 32 are divided into two groups, distributed along the width of the frame on both sides of the frame, and are driven by a motor. Two receiving chains 33 are provided, each corresponding to one of the two groups of receiving sprockets 32. One receiving chain 33 is wound around two receiving sprockets 32 in the same group, facilitating rotation by the motor and the receiving sprockets 32.

[0059] Several egg receiving claws 31 are provided, and all of them are installed on the receiving chain 33 so that the receiving claws 31 can be driven by the receiving chain 33 to move along the rotation path of the receiving chain 33. The egg receiving claws 31 have egg receiving openings that are adapted to the size and shape of the larger end of the egg, so that the egg is transported with the larger end down and the smaller end up with the egg receiving claws 31.

[0060] Reference Figure 9 The rotating path of the receiving chain 33 is provided with an inclined receiving section 301. The bottom of the inclined receiving section 301 is located at the bottom of the turning ramp 26, and the inclined receiving section 301 is set away from the turning ramp 26 from bottom to top. The receiving claw 31 receives the eggs in the inclined receiving section 301. When the receiving claw 31 moves to the inclined receiving section 301, the receiving claw 31 is inclined towards the turning ramp 26 from bottom to top. This reduces the drop height of the eggs and ensures that the egg-catching opening of the receiving claw 31 matches the parabolic drop path of the eggs, so that the eggs are accurately aligned and fall into the receiving claw 31.

[0061] Reference Figure 10 Several egg-receiving claws 31 are arranged in several rows, and these rows of egg-receiving claws 31 are sequentially installed on the receiving chain 33 along its rotation direction. The egg-receiving claws 31 in each row are distributed along the width of the frame to facilitate the reception of eggs falling from the central channels 251. The egg-receiving claws 31 in each row slide along the width of the frame, allowing the horizontal spacing between them to be adjusted. Figure 11 The bottom of the receiving egg claw 31 is provided with an egg claw guide post 311. The egg claw guide post 311 is circular and extends along the height direction of the receiving egg claw 31, so as to adjust the distance between two horizontally adjacent receiving egg claws 31 by moving the egg claw guide post 311.

[0062] Reference Figure 11The egg receiving assembly 3 also includes a top guide rail 34 and a bottom guide rail 35. Two top guide rails 34 are provided, distributed along the width of the frame on both sides. Both top guide rails 34 are fixedly installed on the frame, and are tapered from the input end of the receiving conveyor belt towards the output end. When the receiving claws 31 move along the top rotation path of the receiving chain 33, the claw guide posts 311 of the receiving claws 31 at both ends of the same row respectively abut against the two top guide rails 34 and slide along the surface of the top guide rails 34. This causes the receiving claws 31 at both ends to slide towards the center of the frame and push adjacent receiving claws 31 to slide. Consequently, the receiving claws 31 in the same row gradually converge as they move along the top rotation path of the receiving chain 33, adjusting the distance between two adjacent receiving claws 31 to fit the egg tray, thus facilitating the accurate placement of eggs into the egg tray.

[0063] Several bottom guide rails 35 are provided, all located at the bottom of the top guide rail 34, and all are fixedly installed on the frame. The bottom guide rails 35 are arranged diverging from the output end of the receiving conveyor belt towards the input end. After the receiving egg claws 31 are turned around by the mounting and turning assembly 4, each row of receiving egg claws 31 moves sequentially toward the bottom guide rails 35. The egg claw guide posts 311 of each receiving egg claw 31 in the same row enter each bottom guide rail 35 and slide along the interior of the bottom guide rail 35, so that each receiving egg claw 31 slides toward the edge of the frame and disperses, thereby adjusting the spacing of each receiving egg claw 31 to match the spacing of the central channel 251, which is conducive to the accurate dropping of eggs into the receiving opening of the receiving egg claws 31.

[0064] Several bottom guide rails 35 are provided, and the distribution direction of the several bottom guide rails 35 is consistent with the distribution direction of the two top guide rails 34. The several bottom guide rails 35 are respectively arranged corresponding to each receiving egg claw 31 in the same row, so that the receiving egg claw 31 can slide and engage with the bottom guide rail 35 through the egg claw guide post 311. In addition, the opening of the bottom guide rail 35 facing the mounting and turning assembly 4 is flared, so that the egg claw guide post 311 can slide into the bottom guide rail 35.

[0065] Reference Figure 10 and Figure 11The egg receiving assembly 3 also includes egg claw guide wheels 36 and egg claw guide plates 37. Several egg claw guide wheels 36 are provided, all coaxially fixedly mounted on the receiving sprocket 32, allowing the egg claw guide wheels 36 to rotate synchronously with the receiving sprocket 32. The spacing of the egg claw guide wheels 36 is adapted to the spacing of each central channel 251, and an annular guide groove is provided on the outer circumferential surface of the egg claw guide wheels 36. This allows for secondary positioning and adjustment of the egg claw guide posts 311 after they disengage from the bottom guide rail 35, further adjusting the spacing of each receiving egg claw 31 in the same row to match the spacing of the central channels 251, thus facilitating the accurate falling of eggs into the receiving opening of the receiving egg claw 31.

[0066] Several egg claw guide plates 37 are provided, and the egg claw guide plates 37 are all located on the top of the egg claw guide wheel 36. The egg claw guide plates 37 are distributed on both sides of the egg claw guide wheel 36, and the spacing between two adjacent egg claw guide plates 37 is adapted to the width of the receiving egg claw 31 and the spacing of each central channel 251, so as to facilitate secondary positioning and adjustment of the receiving egg claw 31, so that the eggs fall more accurately into the receiving opening of the receiving egg claw 31.

[0067] Reference Figure 10 and Figure 11 The turning assembly 4 includes a turning arc plate 41, an arc plate mounting rod 42, and a one-way inclined plate 43. Several turning arc plates 41 are provided, arranged in pairs as a group. Each group of turning arc plates 41 corresponds to one of the receiving egg claws 31 in the same row, allowing the eggs conveyed by the receiving egg claws 31 in the same row to turn around via the respective group of turning arc plates 41. Figure 12 A turning gap 411 is formed between the two turning arc plates 41 in the same group. The width of the turning gap 411 is adapted to the small end of the egg so that the small end of the egg can be inserted into the turning gap 411. This allows the egg to turn around stably along the turning arc plate 41 and makes it less likely for the egg and the receiving egg claw 31 to have lateral displacement during the turning process. This ensures that the egg claw guide post 311 of the receiving egg claw 31 slides accurately into the bottom guide rail 35.

[0068] Reference Figure 12 The radius α of the turning arc plate 41 is greater than (5π) / 6 (radians in rad), and in this embodiment, the radius α of the turning arc plate 41 is (17π) / 18. The top of the turning arc plate 41 is located at the top of the receiving conveyor belt, and the bottom of the turning arc plate 41 is located at the bottom of the receiving conveyor belt. The top of the turning arc plate 41 is rotatably coupled to the frame via a rotating rod, allowing the turning arc plate 41 to rotate as the eggs are turned around, thereby reducing the adverse effects of damage to large-sized eggs and changes in egg conveying speed. Figure 11The arc plate mounting rod 42 is fixedly installed on the frame. Several swing keyways 421 are provided through the arc plate mounting rod 42, distributed along the width of the frame. Each swing keyway 421 corresponds to a group of turning arc plates 41, and all swing keyways 421 extend vertically. Two swing arc plates in the same group are fixedly equipped with arc plate limiting posts 412. These posts 412 are swingably inserted into the swing keyways 421 to limit the rotation angle of the turning arc plates 41. This reduces the risk of smaller eggs falling and breaking when turning along the arc plates 41 without effectively engaging the turning gap 411. In addition, the arc plate limiting post 412 is also fitted with a reset spring 413. The two ends of the reset spring 413 are fixedly installed on the arc plate mounting rod 42 and the turning arc plate 41, respectively, so that the turning arc plate 41 can rotate and reset in time.

[0069] Reference Figure 12 The one-way ramp 43 is located on the side of the turning arc plate 41 away from the receiving egg claw 31. The top of the one-way ramp 43 is rotatably and elastically mounted on the frame, and the one-way ramp 43 is inclined from top to bottom toward the receiving egg claw 31.

[0070] Furthermore, the egg tray loading machine also includes an egg tray conveyor belt 6, which is used to transport egg trays in a horizontal direction, and the type of egg tray conveyor belt 6 can be selected from those known in the art. For example, the egg tray conveyor belt 6 can drive the egg tray pusher plate 61 to move in a horizontal direction through a chain and sprocket, thereby pushing the egg trays located on the egg tray platform forward through the egg tray pusher plate 61.

[0071] When the egg tray is conveyed forward under the strong pushing force of the egg tray pusher plate 61, the egg tray will push the one-way ramp 43 upward, thus allowing the one-way ramp 43 to make way for the conveying of the egg tray. Furthermore, the one-way ramp 43 will extend into the interior of the egg tray after it comes to a stop. When the egg tray is subjected to other external disturbances, the one-way ramp 43 extending into the interior of the egg tray will prevent the egg tray from moving in the opposite direction, making it easier for the egg tray to accurately stop at the designated position. This ensures that the eggs, after leaving the output end of the turning arc plate 41, can accurately fall into the interior of the egg tray.

[0072] In addition, combined Figure 11 and Figure 12 A conveyor sensor 7 is fixedly installed on the frame and is located at the input end of the turning arc plate 41. The conveyor sensor 7 is used to detect the forward conveying speed of the same row of eggs, and is electrically connected to the egg tray conveyor belt 6 so that after a row of eggs falls into the egg tray, the egg tray conveyor belt 6 pushes the egg tray forward by one row, thereby ensuring that each row of eggs can accurately fall into the inside of the egg tray.

[0073] The implementation principle of an egg loading machine according to an embodiment of this application is as follows: the feeding conveyor belt 5 transports disordered eggs to the egg diversion component 1, and then, under the action of the diversion swivel plate 12 and the diversion partition plate 11, the eggs are divided into several columns and conveyed forward. During the forward conveying of the eggs through the feeding conveyor belt 5 and the middle conveyor belt, because the center of gravity of the eggs is biased towards the small end, the small end of the eggs will move towards the diversion partition plate 11 and the middle partition plate 25 on the small end side, and finally conform to the diversion partition plate 11 and the middle partition plate 25 for movement.

[0074] When the middle conveyor belt transports the eggs to the conveyor end, the turning inclined surface 261 of the turning inclined block 26 blocks the small end of the egg, causing the two ends of the egg to gradually generate a differential speed, so that the egg falls into the receiving claw 31 with the large end facing down.

[0075] Multiple egg receiving claws 31 gradually converge and align with each turning arc plate 41 under the action of two top guide rails 34. After the eggs move to the turning arc plate 41 with the receiving conveyor belt, the small end of the eggs gets stuck in the turning gap 411 and flips and slides along the turning arc plate 41, so that the eggs are sent into the egg tray with the small end down and the large end up.

[0076] During the process of transporting the eggs to the palletizing position by the central conveyor belt and the receiving conveyor belt, the eggs are gradually guided to complete the turning by the turning inclined block 26 and the turning arc plate 41. The impact on the eggs is small, reducing the use of drive components such as motors. Thus, while ensuring the turning effect of the eggs, the structure of the palletizing machine is simplified, making the palletizing machine easier to maintain.

[0077] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
