Description

An egg transfer device Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to an egg transfer device. Background Technology

[0002] In food processing, eggs need to be processed automatically by a shell-cracking machine to release the egg liquid. However, in actual production, eggs purchased by factories are usually neatly arranged in trays, with multiple trays stacked on top of each other. Currently, the operation of removing the eggs from the trays one by one and placing them into the shell-cracking machine's feed inlet is mostly done manually. Although some factories with better financial resources have introduced robotic arms to automatically pick up eggs, the work of removing the top empty tray after all the eggs on one tray have been picked up still requires manual operation. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides an egg transfer device that automatically transfers eggs and automatically removes empty trays.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed:

[0005] An egg transfer device includes multiple trays, a conveyor, a linear travel mechanism, and a clamping mechanism.

[0006] Eggs are arranged on a tray;

[0007] The conveyor is used to transport stacked pallets toward the tail end, and windows are provided on both sides of the tail end of the conveyor.

[0008] The linear stroke mechanism is installed above the conveyor table by means of suspension or support frame, and a lifting component is connected below it. The movable end of the bottom of the lifting component is connected to the adsorption plate. Multiple vacuum adsorption hoods are provided at the bottom of the adsorption plate. The adsorption plate is located above the tail end of the conveyor table, and the number and position of the vacuum adsorption hoods correspond one-to-one with the number and position of eggs on a tray. The vacuum adsorption hoods are used to adsorb eggs.

[0009] The clamping mechanism is located on the suction plate and is used to clamp a tray on the top layer.

[0010] Furthermore, the vacuum adsorption hood is funnel-shaped with an opening facing downwards.

[0011] Furthermore, the vacuum adsorption cover is made of soft plastic or soft rubber.

[0012] Furthermore, the bottom of the four side walls of the tray is provided with notches. The clamping mechanism includes a first bidirectional telescopic rod and L-shaped clamps at both ends. The first bidirectional telescopic rod is located on the top of the adsorption plate, and the two L-shaped clamps are located on both sides of the adsorption plate. The extension and retraction direction of the first bidirectional telescopic rod is perpendicular to the conveying direction of the conveyor table. When the vacuum adsorption hood adsorbs the eggs, the horizontal section of the L-shaped clamp corresponds to the notch of the corresponding tray.

[0013] Furthermore, a stop plate is provided at the rear end of the conveyor to stop the pallet.

[0014] Furthermore, it also includes an attitude adjustment mechanism. The height difference between the bottom surface of the window and the top surface of the notch of the bottom tray is greater than the thickness of the horizontal section of the L-shaped clamp, which allows the L-shaped clamp to hold the bottom tray. The attitude adjustment mechanism includes a second bidirectional telescopic rod and supports at both ends. The second bidirectional telescopic rod is located on the top of the base and below the tail end of the conveyor. The two supports are located in the corresponding windows. When the two supports are brought together, they are used to adjust the attitude of a stack of trays at the tail end.

[0015] The beneficial effects of this utility model are: it can automatically transfer the eggs on the tray to the feeding port of the shell-breaking machine, and it can also automatically separate the empty tray from the other trays carrying eggs, without the need for manual removal of the empty tray.

[0017] Figure 2 shows a front view of the egg transfer device. Detailed Implementation

[0018] As shown in Figure 1, this embodiment provides an egg transfer device, including multiple trays 4, a conveyor 1, a linear travel mechanism 2, and a clamping mechanism 3.

[0019] Specifically, each tray 4 has eggs arranged on it, and four trays 4 are stacked together as a group.

[0020] Specifically, the conveyor 1 is used to transport the stacked pallets 4 toward the tail end. The tail end of the conveyor 1 is provided with a stop plate for stopping the pallets 4. Windows 12 are provided on both sides of the tail end of the conveyor 1. The bottom surface of the windows 12 is preferably higher than the table surface of the conveyor 1, and the bottom surface of the windows 12 is lower than the top surface of the bottom pallet 4.

[0021] Specifically, the linear stroke mechanism 2 is mounted above the conveyor table 1 via suspension or support frame. A lifting assembly 21 is connected below the linear stroke mechanism 2. The movable end of the bottom of the lifting assembly 21 is connected to the adsorption plate 22. Multiple vacuum adsorption covers 23 are provided at the bottom of the adsorption plate 22. The adsorption plate 22 is located above the tail end of the conveyor table 1, and the number and position of the vacuum adsorption covers 23 correspond one-to-one with the number and position of the eggs on a tray 4. The lifting assembly 21 is used to move the adsorption plate 22 and the vacuum adsorption covers 23 up and down. The vacuum adsorption covers 23 are used to adsorb the eggs. The linear stroke mechanism 2 is used to move the lifting assembly 21 and the adsorption plate 22 horizontally.

[0022] There are many ways to implement the linear stroke mechanism 2, and its structure and principle will not be elaborated here. For example, it can be implemented by using a motor to drive the lead screw. There are many ways to implement the lifting component 21, such as using a cylinder or hydraulic cylinder for drive.

[0023] Preferably, in order to more stably adsorb eggs, the vacuum adsorption cover 23 is a funnel shape with a downward opening. The vacuum adsorption cover 23 is made of soft plastic or soft rubber. The term "soft" means that it can deform and play a buffering role to prevent the pressure from being too great and damaging the eggs when the vacuum adsorption cover 23 moves downward.

[0024] Specifically, the clamping mechanism 3 is mounted on the adsorption plate 22 and is used to clamp a tray 4 on the top layer. There are many clamping methods for the clamping mechanism 3; this embodiment adopts the following measures:

[0025] As shown in Figures 1 and 2, the clamping mechanism 3 includes a first bidirectional telescopic rod 31 and two L-shaped clamping plates 32 located at its two ends. The first bidirectional telescopic rod 31 is located on the top of the adsorption plate 22, and the two L-shaped clamping plates 32 are located on both sides of the adsorption plate 22. The first bidirectional telescopic rod 31 is driven by a cylinder or a hydraulic cylinder to adjust the distance between the two L-shaped clamping plates 32. The extension and retraction direction of the first bidirectional telescopic rod 31 is perpendicular to the conveying direction of the conveying table 1. The bottom of the four side walls of the tray 4 is provided with notches 41. When the vacuum adsorption hood 23 moves down with the adsorption plate 22 and adsorbs the eggs, the horizontal section of the L-shaped clamping plate 32 corresponds to the notch 41 of the corresponding tray 4.

[0026] More specifically, to ensure a more precise alignment between the vacuum adsorption hood 23 and the eggs on a tray 4, the device also includes an adjustment mechanism 5. The adjustment mechanism 5 includes a second bidirectional telescopic rod 51 and supports 52 located at both ends of it. The second bidirectional telescopic rod 51 is located on the top of the base and below the tail end of the conveyor table 1. The two supports 52 are located in the corresponding windows 12. The second bidirectional telescopic rod 51 is driven by a cylinder or hydraulic cylinder to adjust the distance between the two supports 52. When the two supports 52 are brought together, they are used to adjust the posture of the stack of trays 4 at the tail end. Note that the supports 52 do not need to clamp the trays 4; they only serve to adjust the posture and limit the position.

[0027] In addition, the height difference between the bottom surface of window 12 and the top surface of the notch 41 of the bottom tray 4 must be greater than the thickness of the horizontal section of the L-shaped clamp 32, so that the L-shaped clamp 32 can hold the bottom tray 4 in subsequent steps. It should also be noted that the structure and position of the bracket 52 should not interfere with the movement trajectory of the L-shaped clamp 32.

[0028] How to use:

[0029] The conveyor 1 transports the stacked pallets 4 toward the tail end, and the stop plate stops the pallets 4;

[0030] The second bidirectional telescopic rod 51 brings the two supports 52 together, thereby adjusting the posture of the stack of trays 4 at the tail end;

[0031] The lifting assembly 21 moves the adsorption plate 22 down, and the vacuum adsorption cover 23 and the clamping mechanism 3 move down accordingly. The vacuum adsorption cover 23 contacts and adsorbs the corresponding egg. The first bidirectional telescopic rod 31 reduces the distance between the two L-shaped clamps 32 until the horizontal section of the L-shaped clamp 32 is inserted into the notch 41 of the top tray 4.

[0032] The lifting assembly 21 moves the adsorption plate 22 upward, and the vacuum adsorption cover 23, clamping mechanism 3 and tray 4 move upward accordingly; the linear stroke mechanism 2 moves the lifting assembly 21 and adsorption plate 22 horizontally until the tray 4 is outside the conveyor table 1; the first bidirectional telescopic rod 31 widens the distance between the two L-shaped clamps 32, and the tray 4 will fall under the action of gravity, thereby realizing the separation of the tray 4 from the egg; the linear stroke mechanism 2 continues to move the lifting assembly 21 and adsorption plate 22 horizontally until the egg is moved to the feeding port of the shell-breaking machine; the lifting assembly 21 moves the adsorption plate 22 downward, thereby placing the egg at the feeding port of the shell-breaking machine, and the vacuum adsorption cover 23 releases the egg.

[0033] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
