Description

Technical Field

[0001] This utility model relates to the field of egg processing equipment, and in particular to an egg pallet lifting and conveying device. Background Technology

[0002] Egg cartons containing eggs are typically stacked into pallets for easy transport. To make the pallets more compact and stable, adjacent layers are usually staggered by 90°. For example, in a 5x6 array of egg trays, the first layer of pallets is arranged in 5 horizontal columns, and the second layer in 6 horizontal columns. In the egg processing workshop, depalletizing equipment is used to dismantle the pallet stacks before removing the eggs. Each time a layer of pallets is removed, the pallet stack is raised to a certain height.

[0003] However, the current depalletizing equipment can only place one set of egg trays and can only complete the depalletizing work of a single set of egg trays, which is inefficient; moreover, it cannot meet the requirements for using egg trays with staggered stacks, making it impractical.

Detailed Implementation

[0019] 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.

[0020] 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.

[0021] like Figures 1-6 As shown, an egg tray stack lifting and conveying device includes a liftable beam G100. Above the beam G100 are several rotatable egg tray positioning plates G110 arranged in a straight line. Each positioning plate has a limiting groove G111 that mates with the bottom of one row of egg slots on the egg tray. This egg tray stack lifting and conveying device can simultaneously convey multiple egg tray stacks for lifting and conveying egg trays during the unpacking process. The orientation of the positioning plates G110 can be adjusted for egg tray stacks with staggered placement, making it convenient, practical, and highly efficient.

[0022] The limiting groove G111 of the egg tray positioning plate G110 is formed between a pair of limiting strips. According to the specifications of the egg tray slots at the bottom of the egg tray stack, the limiting groove G111 can be set in the middle when the number of rows is odd, and a pair is set symmetrically on the left and right when the number of rows is even.

[0023] In this embodiment, a frame G200 and a lifting transmission mechanism G300 for driving the crossbeam to rise and fall are also included. The lifting transmission mechanism G300 includes a swing beam G310, one end of which is hinged to the frame and the other end of which is connected to the lower part of the crossbeam G100 via a bracket G320. The bracket is hinged at both ends to the other end of the swing beam and the lower part of the crossbeam, respectively. A cam G340 is provided below the swing beam, and a pressure roller G311 is rotatably connected to the swing beam and presses against the top of the cam. The swing beam relies on its own weight to keep the pressure roller G311 pressed against the top of the cam. The outer contour of the cam is used to achieve lifting and lowering. The rise of the swing beam causes the crossbeam to be lifted through the bracket. A seat connected to the bracket is provided at the lower part of the crossbeam, and the end of the crossbeam and the bracket are both located in the middle of the seat. To improve stability, two sets of lifting transmission mechanisms G300 can be set, and the cams of the two sets of lifting transmission mechanisms G300 are mounted on the same camshaft. The camshaft is driven by a motor, and the main shaft of the motor is connected to the camshaft through a chain and a sprocket.

[0024] In this embodiment, in order to ensure that the crossbeam does not deflect at an angle when it is raised or lowered, at least two equal and parallel stabilizing rods G330 are provided on the side of the swing beam G310. One end of the stabilizing rod is hinged to the frame and the other end is hinged to the crossbeam to form a parallel four-bar linkage structure. There can be two, three, four, five or six stabilizing rods. The parallel four-bar linkage mechanism composed of the stabilizing rods, the frame (which is fixed) and the crossbeam ensures that the crossbeam is raised and lowered stably.

[0025] In this embodiment, a rotary transmission mechanism G400 is also included to drive the egg tray positioning plate to reciprocate 90°. The bottom of the egg tray positioning plate is provided with a rotating shaft G120 rotatably connected to the crossbeam. A swing plate G130 is fixedly connected to the lower part of the rotating shaft. The swing plates on the rotating shafts of all the egg tray positioning plates are connected together by a linkage rod G140. The rotary transmission mechanism G400 includes a swing rod A410 located on the side of the swing beam away from the crossbeam. The lower end of the swing rod A410 is hinged to the frame. A push-pull rod G420 is connected between the upper end of the swing rod A410 and the swing plate on the rotating shaft of one of the egg tray positioning plates. The swinging motion of swing A drives the rotation of the egg tray positioning plate through the push-pull rod, adjusting the orientation of the egg tray positioning plate; the adjacent layers of egg trays are stacked at 90° offset, so that the positions of the upper and lower egg trays are staggered, which can ensure the stability of the egg tray stack and reduce the height; therefore, the egg tray positioning plate that can rotate 90° back and forth can meet the requirements of using egg tray stacks with staggered egg trays.

[0026] In this embodiment, the swing rod A is provided on the side of the swing member G430, which is coaxially hinged to it. The swing member G and the swing rod A can be coaxially hinged to the corresponding end of the stabilizing rod. A U-shaped plate G431 is fixedly connected to the swing member. The swing rod A is located in the middle of the U-shaped plate. Buffer springs G432 are respectively sandwiched between the two side plates of the U-shaped plate and the swing rod A. When the swing member G swings, it drives the swing rod A to swing, which in turn drives the rotating shaft of the corresponding egg tray positioning plate to rotate through the push-pull rod. Since the swing plates on the rotating shafts of all egg tray positioning plates are connected by linkage rods, all egg tray positioning plates can move synchronously. The addition of buffer springs can buffer the motion transmission between the swing member G430 and the swing rod A.

[0027] In this embodiment, the rotary transmission mechanism G400 further includes a turntable G440 coaxially arranged with the cam. The turntable has a cam groove, and a rocker arm BG450 is provided on the side of the turntable. The lower end of the rocker arm B is hinged to the frame, and a roller extending into the cam groove is rotatably connected to the middle of the rocker arm B so that when the turntable rotates, the rocker arm B swings through the cooperation of the cam groove and the roller. A connecting rod G460 connects the upper end of the rocker arm B to the swinging component. The coaxial arrangement of the turntable and the cam can improve the synchronization of the lifting action and the rotation action of the egg tray positioning plate. Each time the crossbeam is raised, the egg tray positioning plate rotates 90° once.

[0028] In practice, the swing arm A can also be driven by a motor via a crank-connecting rod mechanism, and the control system can control the motor to ensure synchronization.
