Description

Technical Field

[0001] This application relates to the field of egg transport, and in particular to an egg turning and palletizing device. Background Technology

[0002] During the production line transport process, eggs are usually loaded into egg cups with the larger end facing down and transported by chain. This is to reduce the impact during transport by using the larger end, which has an air chamber, thus minimizing the risk of damage during the production line transport process.

[0003] After the eggs have undergone cleaning, disinfection, and testing, they often need to be placed in egg trays to support multiple eggs. During the traying process, the larger end of the egg with the air cell should usually face upwards to help preserve the freshness of the eggs.

[0004] In existing related technologies, in order to facilitate turning eggs so that the larger end of the egg changes from a downward-facing position, a turning device is often used to turn the eggs. Specifically, please refer to the patent document CN206288290 U, entitled "Egg Loading Machine". This utility model patent uses an egg turning mechanism, an egg dropping guide plate, and a rotating egg dropping mechanism to turn the eggs so that the eggs are arranged in a loading state with the larger end facing upwards.

[0005] Regarding the technologies mentioned above, existing U-turn equipment has a relatively complex structure and presents technical problems related to maintenance costs. Summary of the Invention

[0006] To simplify the egg turning equipment and reduce its maintenance costs, this application provides an egg turning and loading device.

[0007] The egg product turning and palletizing device provided in this application adopts the following technical solution:

[0008] An egg product turning and loading device includes a conveyor chain and an egg guard plate;

[0009] The conveyor chain rotates cyclically in a vertical plane, and the conveyor chain is provided with a flipping section;

[0010] The conveyor chain is equipped with an egg cup, which has an egg placement cavity for placing eggs. The egg placement cavity has an opening. After the egg tray passes through the turning section of the conveyor chain, the opening of the egg placement cavity changes from an upward state to a downward state.

[0011] The egg-protecting plate is curved in a vertical plane and is arranged in a "C" shape. The egg-protecting plate surrounds the turning section of the conveyor chain, and the top and bottom ends of the egg-protecting plate are located at the top and bottom of the conveyor chain, respectively.

[0012] By adopting the above technical solution, when the eggs move with the conveyor cup to the turning section of the conveyor chain, the eggs and the conveyor cup rotate together in the vertical plane with the conveyor chain body, causing the egg placement cavity of the conveyor cup to change from an upward state to a downward state. When the conveyor cup passes through the turning section, the egg guard plate is tightly fitted from the top until the eggs move to the bottom of the egg guard plate, completing the turn and detaching from the bottom of the egg guard plate. Thus, the egg turning is completed by the egg guard plate and the conveyor chain, simplifying the turning equipment and reducing the maintenance cost of the egg turning equipment.

[0013] Optionally, the top of the egg guard plate is curved upwards.

[0014] By adopting the above technical solution, when the egg comes into contact with the top of the egg guard, the upward-curving egg guard is less likely to collide violently with the egg, making the egg less likely to be damaged by bumps.

[0015] Optionally, the conveyor chain may have a horizontal section;

[0016] The egg product turning and loading device also includes an egg tray conveying platform, which is used to convey egg trays to be loaded with eggs in a horizontal direction, and the egg tray conveying platform is located at the bottom of the bottom end of the egg protection plate.

[0017] By adopting the above technical solution, after the eggs fall from the bottom of the egg protector, they fall directly into the egg tray, reducing the falling height of the eggs and reducing the occurrence of egg breakage.

[0018] Optionally, the egg protection plate is movably connected to the external frame via a flexible support member.

[0019] By adopting the above technical solution, the egg guard can adapt its posture according to the size of the eggs, ensuring that the egg guard stays in close contact with the eggs for a longer period of time and reducing the shaking of the eggs during the flipping and turning process.

[0020] Optionally, the flexible support may be a spring or a rubber pad.

[0021] By adopting the above technical solutions, the structure of the flexible support component is simpler and more reliable, making it easier for large-scale industrial production.

[0022] Optionally, the flexible support is provided in a plurality of parts, and the plurality of flexible support are located at the top and middle of the egg protection plate.

[0023] By adopting the above technical solution, the egg guard plate can closely fit the egg as it rotates, reducing the shaking of the egg during the rotation process.

[0024] Optionally, the egg-protecting plate is integrally formed, and the egg-protecting plate is smoothly positioned on the side facing the flipping section of the conveyor chain.

[0025] By adopting the above technical solutions, it is beneficial to reduce the occurrence of damage to eggs caused by bumps and knocks from the egg guard.

[0026] Optionally, the egg protection plate is of the type of elastic membrane.

[0027] By adopting the above technical solution, the egg guard adapts to eggs of different sizes through its own elasticity, reducing the complexity of the structure and allowing the egg guard to fit tightly to the eggs for a longer period of time, reducing the occurrence of shaking of the eggs during flipping and turning.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When the eggs move with the conveyor cup to the turning section of the conveyor chain, the eggs and the conveyor cup rotate together in the vertical plane with the conveyor chain body, causing the egg placement cavity of the conveyor cup to change from an upward to a downward position. As the conveyor cup passes through the turning section, it fits snugly against the top of the egg guard plate until the eggs move to the bottom of the egg guard plate, completing the turn and detaching from the bottom of the egg guard plate. This process of turning the eggs is completed through the egg guard plate and the conveyor chain, simplifying the turning equipment and reducing the maintenance cost of the egg turning equipment.

[0030] 2. The egg guard can easily adjust its posture according to the size of the eggs, ensuring that the egg guard stays in close contact with the eggs for a longer period of time and reducing the shaking of the eggs during flipping and turning.

[0031] 3. The egg guard adapts to eggs of different sizes through its own elasticity, reducing the complexity of the structure and allowing the egg guard to fit the eggs tightly for a longer time, reducing the shaking of the eggs during flipping and turning. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0036] Example 1:

[0037] Embodiment 1 of this application discloses an egg-turning tray-loading device. (Refer to...) Figure 1 The egg turning and loading device includes a conveyor chain 1, an egg guard plate 2, and an egg tray conveying platform 3.

[0038] The conveyor chain 1 rotates cyclically in a vertical plane, and the conveyor chain 1 is provided with a horizontal section 101 and a turning section 102. The horizontal section 101 of the conveyor chain 1 moves in the horizontal direction, and the turning section 102 of the conveyor chain 1 rotates in the clockwise direction.

[0039] A plurality of egg cups 11 are fixedly installed on the conveyor chain 1. The egg cups 11 are distributed along the rotation direction of the conveyor chain 1 so that the egg cups 11 can move along the egg cup conveying direction via the conveyor chain 1. The egg cups 11 have egg placement cavities 111 for placing eggs, and the egg placement cavities 111 have openings for placing eggs into the egg placement cavities 111. When an egg is placed inside the egg placement cavity 111, the larger end of the egg is away from the opening of the egg placement cavity 111, and the smaller end of the egg is facing the opening of the egg placement cavity 111. This is so that after the egg cups 11 pass through the turning section 102 of the conveyor chain 1, the opening of the egg placement cavity 111 changes from an upward state to a downward state, thus making the larger end of the egg face upward.

[0040] The egg protector 2 is located on the flipping section 102 of the conveyor chain 1. The egg protector 2 is curved in a vertical plane and arranged in a "C" shape. The top and bottom ends of the egg protector 2 are located at the top and bottom of the conveyor chain 1, respectively, so that the flipping section 102 of the conveyor chain 1 is surrounded by the egg protector 2 in the vertical plane. When the egg tray is flipped through the flipping section 102 of the conveyor chain 1, the eggs placed in the egg placement cavity 111 can fit snugly against the egg protector 2 and are less likely to shake. Furthermore, the top of the egg protector 2 curves upwards, gradually reducing the distance between the egg protector 2 and the conveyor chain 1, which helps to reduce the collision between the eggs and the top of the egg protector 2, thus making the eggs less prone to breakage.

[0041] The egg guard 2 is movably connected to the external frame via the flexible support 12, allowing the egg guard 2 to float in all directions according to the size of the eggs. This helps ensure that the egg guard 2 can adhere to the eggs more easily and for a longer period of time when the eggs are flipped and turned around in the flipping section 102, thereby reducing the occurrence of eggs shaking and falling off.

[0042] Specifically, in this application, two flexible support members 12 are provided, and the two flexible support members 12 are respectively located at the top and middle of the egg guard plate 2, so as to support the egg when it first comes into contact with the egg guard plate 2 and when the egg is flipped to a horizontal position, and to ensure stability during the flipping process. The flexible support member 12 can be a spring or a rubber pad, or other parts that can recover after deformation.

[0043] The egg tray conveyor platform 3 is set horizontally and is located at the bottom of the egg guard plate 2. The egg tray conveyor platform 3 is equipped with an egg tray pusher plate 31, which rotates cyclically in a vertical plane via a chain (not shown in the figure). This allows the egg tray conveyor platform 3 to transport the egg trays containing the eggs to the bottom of the egg guard plate 2 horizontally along the egg tray conveying direction. As a result, after the eggs are flipped and turned, they fall directly onto the egg trays with a small drop height.

[0044] In addition, to improve loading efficiency, in some embodiments, multiple sets of egg cups can be arranged along the width of the conveyor chain 1, so that multiple sets of egg cups can turn the eggs around simultaneously.

[0045] The implementation principle of the egg product turning and loading device in Embodiment 1 of this application is as follows: when the egg product moves with the egg cup 11 to the turning section 102 of the conveyor chain 1, the egg product and the egg cup 11 turn together with the chain body of the conveyor chain 1 in the vertical plane, so that the egg product placement cavity 111 of the egg cup 11 changes from an upward state to a downward state.

[0046] When the egg cup 11 passes through the flipping section 102, the egg cup 11 is opened at the top of the egg protection plate 2 and fits tightly against the egg protection plate 2 until the egg moves to the bottom of the egg protection plate 2, completes the turn, and detaches from the bottom of the egg protection plate 2. Thus, the egg is turned over by the egg protection plate 2 and the conveyor chain 1, which simplifies the turning equipment and reduces the maintenance cost of the egg turning equipment.

[0047] Example 2:

[0048] This application discloses an egg-turning and traying device, referring to... Figure 2 The difference from Example 1 is as follows:

[0049] Difference 1: The flexible support 12 is not provided, and the egg protection plate 2 is directly fixed to the external frame.

[0050] Difference 2: The egg guard 2 is made of elastic material and is integrally molded, and the egg guard 2 is smoothly positioned on the side facing the flipping section 102 of the conveyor chain 1. Specifically, the egg guard 2 can be made of silicone or rubber, allowing it to stretch and deform when in contact with larger eggs to adapt to eggs of different sizes. In addition, in some embodiments, to ensure the smoothness of the surface of the egg guard 2, a friction-reducing layer (not shown in the figure) can be applied to the side of the egg guard 2 facing the flipping section 102. The friction-reducing layer can be formed by processes such as brushing or electroplating.

[0051] 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.
