[0001] The present invention relates to the technical field of egg tray transportation, and more particularly to an egg tray conveying mechanism and an egg product palletizing machine. Background Art

[0002] When packing eggs in laying hen farms, the free-standing eggs must first be placed in the egg trays, and then the single-layer egg trays are stacked one by one, usually 6 layers, and then the boxing operation is carried out. Smaller farms generally stack them manually, but for farms with an annual output of tens of millions of eggs, manual stacking is far from enough, so a device that can efficiently stack egg trays is needed. Summary of the Invention

[0003] In view of the above defects, the present invention provides an egg tray conveying mechanism and an egg palletizer to solve the above problems.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

The balancing component performs a circular orbital motion along the first transmission component, and the balancing component does not rotate while orbiting;

[0011] The support plate is rotatably mounted on the balancing member and is used to lift the egg tray when moved upward and release the egg tray when moved downward;

[0013] Furthermore, a special-shaped fixing block is installed on one side of the balancing component, a connecting rod is installed on the special-shaped fixing block for rotation in a horizontal position, a supporting plate is installed on the connecting rod, a torsion spring is installed between the supporting plate and the special-shaped fixing block, and the torsion spring drives the supporting plate to have a tendency to rotate downward.

[0014] Furthermore, the first transmission component is an outer ring chain, the second transmission component is an inner ring chain, the balancing component is a sprocket, a support shaft is provided at the center of the sprocket, one end of the support shaft is fixedly connected to the outer ring chain, the outer ring of the sprocket is engaged with the inner ring chain, and the first transmission component and the second transmission component are in different planes.

[0015] Furthermore, there are multiple limiters located on both sides of the outer ring chain and the inner ring chain, which limit the movement path of the outer ring chain and the inner ring chain, and the spacing between different positions of the outer ring chain and the inner ring chain is equal; the outer ring chain and the inner ring chain are divided into a vertical part and a horizontal part, and the angle between the vertical part and the horizontal part is 90 degrees. The connecting position between the vertical part and the horizontal part is a buffer part, and the buffer part is an irregular arc.

[0017] Furthermore, it also includes a conveying mechanism 1 and a conveying mechanism 2. The conveying mechanism 1 transfers the single-layer egg tray to the position where the support plate moves upward, and the conveying mechanism 2 is located at the position where the egg tray moves downward and transfers the stacked egg trays to another workstation.

[0018] Furthermore, a notch is provided on the side of the supporting plate in contact with the egg tray, and a rubber sleeve is provided on the notch. There are multiple pairs of supporting plates, and the spacing between the same pair of supporting plates is smaller than the width of the egg tray and larger than the width of the first conveying mechanism.

[0019] The setting of the rubber sleeve can increase the friction between the supporting plate and the egg tray. By setting the distance between the same pair of supporting plates to be smaller than the width of the egg tray and larger than the width of the conveying mechanism, when the supporting plate moves upward, it can contact the egg tray and avoid contact with the conveying mechanism.

[0024] Furthermore, the egg tray conveying mechanism is installed on the egg palletizer.

[0025] The beneficial effect of the present invention is that the egg trays can be quickly stacked together through the transmission of the first transmission component and the second transmission component, thereby eliminating manual operation and greatly improving the stacking efficiency, meeting the requirements of large-scale egg tray stacking.

[0026] When the moving direction of the balancing component changes, the transmission speed of the second transmission component is faster than the transmission speed of the first transmission component. The extra moving distance of the second transmission component offsets the deflection of the balancing component, driving the supporting plate to move while achieving self-balancing.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] This application provides egg tray conveying mechanism and egg palletizer, please refer to Figure 1-Figure 7 :include;

[0037] Shell 1;

[0038] A first transmission component 2;

[0039] Second transmission component 3;

[0040] The limiter 4 is used to limit the first transmission component 2 and the second transmission component 3 from transmitting along a specified trajectory;

[0041] The balancing component 5 has a rotation axis hinged to the first transmission component 2, and an edge of the balancing component 5 is engaged with the second transmission component 3. The balancing component 5 performs a circular orbital motion along the first transmission component 2, and the balancing component 5 does not rotate while orbiting.

[0042] The supporting plate 6 is rotatably mounted on the balancing member 5 and is used to lift the egg tray when moved upward and release the egg tray when moved downward;

[0043] The power assembly 7 drives the first transmission component 2 and the second transmission component 3 to transmit at the same linear speed.

[0044] Specifically, in actual application, the power assembly 7 drives the first transmission component 2 and the second transmission component 3 to operate at the same linear speed. When the moving direction of the balancing component 5 changes, the transmission speed of the second transmission component 3 is faster than the transmission speed of the first transmission component 2. The extra movement distance of the second transmission component 3 offsets the deflection of the balancing component 5, driving the support plate 6 to move while achieving self-balancing.

[0045] The conveyor mechanism 1 8 transfers the single-layer egg tray to the position where the support plate 6 moves upward. The support plate 6 lifts the single-layer egg tray upward until it moves to the other side of the equipment and falls. When the support plate 6 moves downward, the egg trays are stacked with the support of the conveyor mechanism 2 9. When the stacking reaches the specified number of layers, the stacked egg trays are transferred to another station.

[0046] The power assembly 7 can provide a power source for the first transmission component 2 and the second transmission component 3 and adjust the moving speed ratio between the first transmission component 2 and the second transmission component 3.

[0047] Reference Figure 1 、 Figure 2 、 Figure 3 A special-shaped fixing block 51 is installed on one side of the balancing component 5, and a connecting rod 52 is installed on the special-shaped fixing block 51 for rotation in the horizontal position. The supporting plate 6 is installed on the connecting rod 52, and a torsion spring 53 is installed between the supporting plate 6 and the special-shaped fixing block 51. The torsion spring 53 drives the supporting plate 6 to rotate downward.

[0048] Specifically in actual application, the special-shaped fixing block 51 is in a fixed connection state with the balancing component 5. Through the action of the connecting rod 52, when the supporting plate 6 moves downward and touches an obstacle, it can automatically flip up, making it easier for the supporting plate 6 to move downward. The torsion spring 53 allows the supporting plate 6 to move stably.

[0049] The first embodiment of the first transmission component 2, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The first transmission component 2 is the outer ring chain 21, the second transmission component 3 is the inner ring chain 31, and the balance component 5 is the sprocket 54. A support shaft 541 is provided at the center of the sprocket 54. One end of the support shaft 541 is fixedly connected to the outer ring chain 21. The outer ring of the sprocket 54 is engaged with the inner ring chain 31. The first transmission component 2 and the second transmission component 3 are in different planes.

[0050] Specifically in actual application, a support shaft 541 is provided at the center of the sprocket 54. Through the action of the support shaft 541, the sprocket 54 can rotate along the support shaft 541 as the axis. The movement speed of the outer ring chain 21 and the inner ring chain 31 is the same, but when the movement direction of the sprocket 54 changes, since the turning radius of the inner ring chain 31 is smaller, the displacement of the inner ring chain 31 will be faster than the outer ring chain 21 at the same movement speed. The resulting distance difference just offsets the active rotation of the sprocket 54, so that the sprocket 54 and the support plate 6 are in a horizontal position.

[0051] Reference Figure 1 、 Figure 2 、 Figure 3 , there are multiple limiters 4 and they are respectively located on both sides of the outer ring chain 21 and the inner ring chain 31 to limit the movement path of the outer ring chain 21 and the inner ring chain 31. The spacing between different positions of the outer ring chain 21 and the inner ring chain 31 is equal; the outer ring chain 21 and the inner ring chain 31 are divided into a vertical part 211 and a horizontal part 212, and the angle between the vertical part 211 and the horizontal part 212 is 90 degrees. The connection position between the vertical part 211 and the horizontal part 212 is the buffer part 213, and the buffer part 213 is an irregular arc.

[0052] Specifically, in actual application, the outer ring chain 21 and the inner ring chain 31 have a stable movement path through the action of the limiter 4. By setting the outer ring chain 21 and the inner ring chain 31 at equal distances at different positions, the movement of the sprocket 54 is more stable. When the sprocket 54 moves in the vertical part 211 and the horizontal part 212, the movement speed of the outer ring chain 21 and the inner ring chain 31 is the same; when the sprocket 54 moves to the buffer part 213, due to the smaller turning radius of the inner ring chain 31, the displacement of the inner ring chain 31 will be faster than that of the outer ring chain 21 at the same movement speed. The resulting distance difference just offsets the active rotation of the sprocket 54, so that the sprocket 54 and the support plate 6 are in a horizontal position.

[0053] By setting the buffer portion 213 to be an irregular arc, the curvature of the buffer portion 213 can be manually changed according to actual conditions to control the transmission speed of the outer ring chain 21 and the inner ring chain 31.

[0054] Reference Figure 1 、 Figure 2 and Figure 4The power assembly 7 includes bearings 71 installed on both sides of the shell 1, and a transmission shaft 72 is installed on the inner ring of the bearing 71. Sprockets 73 are installed at both ends of the transmission shaft 72. The sprockets 73 are engaged with the outer ring chain 21. A first power source 74 is provided on one side of the shell 1, and the first power source 74 is connected to the transmission shaft 72 in transmission; bearings 75 are installed on both ends of the transmission shaft 72, and sprockets 76 are installed on the outer ring of the bearing 75. The sprockets 76 are engaged with the inner ring chain 31. A gear table is installed on the inside of the sprocket 76. A second power source 77 is installed at the center of the shell 1, and the second power source 77 is connected to the gear table in transmission.

[0055] Specifically in actual application, the rotation of the first power source 74 directly drives the transmission shaft 72 to rotate, the transmission shaft 72 drives the sprocket 1 73 to rotate, the rotation of sprocket 1 73 drives the outer ring chain 21 to rotate, and the outer ring chain 21 can drive the support plate 6 to move; the rotation of the second power source 77 can drive the gear table and sprocket 2 76 to rotate, and the sprocket 2 76 can directly drive the inner ring chain 31 to rotate, and the inner ring chain 31 can assist the movement of the support plate 6, so that the support plate 6 moves in a horizontal state.

[0056] Reference Figure 1 , and also includes a conveying mechanism 1 8 and a conveying mechanism 2 9. The conveying mechanism 1 8 transfers the single-layer egg tray to the position where the supporting plate 6 moves upward, and the conveying mechanism 2 9 is located at the position where the egg tray moves downward, and transfers the stacked egg trays to another workstation.

[0057] Specifically in practical applications, the egg tray can be driven to move stably through the action of the conveying mechanism 1 8 and the conveying mechanism 2 9 .

[0058] Reference Figure 4 The side of the supporting plate 6 in contact with the egg tray is provided with a notch 61, and a rubber sleeve 62 is provided on the notch 61. There are multiple pairs of supporting plates 6, and the spacing between the same pair of supporting plates 6 is less than the width of the egg tray and greater than the width of the conveying mechanism 8.

[0059] Specifically in practical applications, the friction between the support plate 6 and the egg tray can be increased by setting the rubber sleeve 62. By setting the spacing between the same pair of support plates 6 to be smaller than the width of the egg tray and larger than the width of the conveying mechanism 8, when the support plate 6 moves upward, it can contact the egg tray and avoid contact with the conveying mechanism 8.

[0060] The second embodiment of the first transmission component 2, referring to Figure 1 、 Figure 5 、 Figure 6 and Figure 7The first transmission component 2 is the outer ring 22, the second transmission component 3 is the inner ring gear 32, the balancing component 5 is the gear 55, the power assembly 7 includes a first bearing 711 mounted on the side wall of the housing 1, the outer ring 22 is mounted on the inner ring of the first bearing 711, the inner ring of the outer ring 22 is mounted on the second bearing 712, the inner ring gear 32 is mounted on the inner ring of the second bearing 712, the inner ring of the outer ring 22 is mounted on the inner ring of the second bearing 712, the inner ring of the outer ring 22 is mounted on the inner ring of the gear 1 713, and the inner ring of the inner ring gear 32 is mounted on the inner ring of the gear 2 714;

[0061] A fixed bearing 715 is installed on the side wall of the outer shell 1, and a rotating shaft 716 is installed on the inner ring of the fixed bearing 715. Gear three 717 engaged with gear one 713 and gear four 718 engaged with gear two 714 are installed on the rotating shaft 716; a driving motor 719 is installed at the lower end of the outer shell 1, and the driving motor 719 is connected to the rotating shaft 716 in transmission.

[0062] Specifically in actual application, the gear 55 is engaged with the inner ring gear 32, and the outer ring 22 and the inner ring gear 32 are regular circles. The outer ring 22 can rotate stably through the action of the first bearing 711, and the inner ring gear 32 can rotate stably through the action of the second bearing 712. The inner ring gear 32 and the outer ring 22 are in a state of relative rotation; when the drive motor 719 rotates, it can drive the rotating shaft 716 to rotate, and the rotating shaft 716 drives gear three 717 and gear four 718 to rotate, controlling the transmission ratios of gear one 713 and gear three 717 and gear two 714 and gear four 718, so that gear one 713 and gear two 714 can rotate at the same speed, driving the outer ring 22 and the inner ring gear 32 to rotate at the same linear speed.

[0063] Reference Figure 5 A conveying mechanism 3 10 is installed on the shell 1. Every time a layer of egg tray is placed on the conveying mechanism 3 10, the conveying mechanism 3 10 moves in a horizontal position to keep the multi-layer egg trays stacked vertically.

[0064] Specifically in actual application, since the outer ring 22 and the inner ring gear 32 are regular circles, if the egg tray is placed on the conveying mechanism 3 10, the conveying mechanism 3 10 does not move. As the egg tray is stacked, it will become tilted. Therefore, each time a layer of egg tray is placed on the conveying mechanism 3 10, the conveying mechanism 3 10 moves in a horizontal position to keep the multi-layer egg trays stacked vertically. Finally, the egg tray is moved to the next process through the conveying of the conveying mechanism 3 10.
