[0021] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] like Figures 1-6 As shown, an egg tray stacking device includes an egg tray conveying device 100 and a frame 200 located at the discharge end of the egg tray conveying device 100. The egg tray conveying device 100 is prior art, and its structure will not be described in detail here. A liftable stacking frame 300 is provided in front of the discharge end of the egg tray conveying device. A stacking frame 400 is provided above the discharge end of the egg tray conveying device, capable of reciprocating back and forth between the discharge end of the egg tray conveying device and the stacking frame. An egg tray clamping mechanism is provided at the bottom of the stacking frame, and the stacking frame 400 is driven to reciprocate back and forth by a reciprocating drive mechanism. When the egg tray is conveyed to the discharge end of the egg tray conveying device 100, the egg tray clamping mechanism on both sides of the stacking frame 400 clamps the egg tray. As the stacking frame 400 moves forward, the egg tray is transferred to the top of the stacking frame 300. Then the egg tray clamping mechanism releases, and the egg tray is placed on the stacking frame 300. Each time an egg tray is placed, the stacking frame 300 lowers a certain height. This egg tray stacking device has a short egg tray transfer stroke, which can reduce the risk of falling. The structure is simple and compact. Moreover, the height at which the egg tray is clamped and lifted is relatively low. Even if it falls, the eggs are not easily damaged, making it safe and reliable.

[0024] In this embodiment, the egg tray gripping mechanism includes a pair of gripper plates 410 located on the left and right sides of the bottom of the stacking frame for gripping the egg tray. Several egg suction cups 420 are provided between the two gripper plates. Hooks are provided at the lower part of the gripper plates on both sides. When the two gripper plates swing towards the middle, the hooks extend to the lower side of the egg tray and lift the egg tray slightly away from the egg tray conveying device 100.

[0025] The egg tray clamping mechanism has several egg suction cups 420 added in the middle, which can hold some eggs during the process of clamping and transferring the egg tray, reducing the weight borne by the gripper plates on both sides and further reducing the risk of the egg tray falling.

[0026] In this embodiment, a pair of rotating square steel bars 210 are rotatably mounted on the frame 200, arranged in the front-back direction and passing through both sides of the palletizing frame. The two ends of the gripper plate are fixedly connected to the sliding sleeves 411 that slide in cooperation with the rotating square steel bars. The rotating square steel bars are driven by a motor (i.e., the palletizing motor 500) to reciprocate so as to drive the gripper plate to grasp and release the egg tray. The gripper plate is restricted between the baffles on the front and back sides of the bottom of the palletizing frame. The rotating square steel bars 210 pass through the baffles. During the front-back movement of the palletizing frame, the gripper plate will move back and forth on the rotating square steel bars 210 together. At the same time, when the rotating square steel bars 210 rotate, they can also drive the gripper plate to swing.

[0027] In this embodiment, the reciprocating drive mechanism 600 includes a swing arm 610 whose upper end is rotatably connected to the frame and is driven to reciprocate by a motor (i.e., the palletizing motor 500). The lower end of the swing arm 610 is connected to the palletizing frame 400 through a push rod 620. One end of the push rod 620 is hinged to the lower end of the swing arm, and the other end is movably connected to the palletizing frame. The swing arm swings to drive the palletizing frame to move back and forth. The push rod 620 and the palletizing frame are movably connected through a ball joint, so there will be no jamming.

[0028] In this embodiment, the swing arm 610 and the rotating square steel 210 are driven by the same motor, namely the stacking motor 500. The stacking motor drives the rotating square steel on both sides to reciprocate through the linkage transmission mechanism 700. The reciprocating drive mechanism 600 also includes a swing plate A630 connected to the rotating shaft of the stacking motor. The free end of the swing plate A is provided with a pin. The upper end of the swing arm is fixedly connected to a crank arm 640. The back of the crank arm is provided with a groove that slides with the pin.

[0029] In this embodiment, the linkage transmission mechanism 700 includes a linkage shaft 710 rotatably mounted on the frame and arranged parallel to the rotating shaft of the palletizing motor. Swing plates B720 are fixedly connected to both ends of the linkage shaft, and swing plates C730 are fixedly connected to the rotating square steel on both sides. A longitudinal connecting rod 740 connects the swing plates B and C on the same side so that the rotating square steel rotates when the linkage shaft rotates. A swing plate D750 is fixedly connected to the middle of the linkage shaft. A cam 760 is also provided on the rotating shaft of the palletizing motor, and a swing plate abutting against the upper side of the cam and hinged to the frame is provided beside the cam. The support 770 has a push-pull rod 780 connected between the swing support and the swing plate D. A spring 790 is also connected between the swing support and the frame to pull the swing support downward. The stacking motor drives the rotating square steel on both sides to rotate through the linkage transmission mechanism 700. When the cam lifts the swing support 770, it drives the linkage shaft 710 to rotate through the push-pull rod 780. The linkage shaft 710 drives the rotating square steel to rotate through the longitudinal linkages 740 at both ends, so as to realize the gripper plate to clamp. After the cam 760 rotates, the spring 790 pulls the swing support 770 to return to its original position, so as to realize the return of the gripper plate.

[0030] In this embodiment, the front side of the stacking rack 400 is provided with a push plate 430 for pushing the egg tray stacks on the stacking rack forward away from the stacking rack; after a certain height of egg trays are stacked on the stacking rack 300, the stacking rack 300 rises, and when the stacking rack 400 moves forward, it pushes the stacked egg tray stacks away from the stacking rack 300 through the push plate, and at the same time places the first egg tray of the next stack on the stacking rack 300.

[0031] In this embodiment, a discharge platform 800 for receiving egg trays is provided on the side opposite to the stacking rack and the pusher plate. The discharge platform can also be a conveying device.

[0032] In this embodiment, the stacking rack is provided with rollers A310, and the frame is provided with a vertical track 220 that works in conjunction with rollers A; the bottom of the stacking rack is provided with rollers B440, and the frame is provided with a horizontal track 230 that works in conjunction with rollers B.

[0033] In this embodiment, the stacking rack is controlled to lift by a lifting mechanism 900. The stacking rack 300 has chains 920 driven by a motor (i.e., lifting motor 910) on both sides above it. A transverse connecting rod 930 is connected between the chains on both sides. Lifting rods 940 are connected between the two ends of the transverse connecting rod and the two sides of the stacking rack. The lifting motor 910 is a double-output shaft motor. The two ends of the double-output shaft motor are respectively provided with driving sprockets. A driven sprocket is provided below the two driving sprockets. The driving sprockets and driven sprockets on both sides are respectively installed on the chains on both sides.

[0034] In this embodiment, the egg tray conveying device 100 is provided with a baffle at the discharge end to block the egg tray. The baffle is fixedly connected to the flipping shaft below. The flipping shaft is rotated to control the baffle to flip up and down, so as to achieve interception and release. The flipping shaft can be driven to rotate by a cylinder or a motor.
