Description

Technical Field

[0001] The invention belongs to the technical field of food processing machinery, in particular to an automatic egg posture adjustment conveyor. Background Art

[0002] In the process of conveying eggs, a conveyor belt with rollers is usually used. This conveyor belt has a long conveying distance. The purpose is to set the conveyor belt to adjust the posture of the eggs during the conveying process. The egg posture conveyor of the prior art has the following problems:

[0003] 1. The conveyor belt has a long transmission distance and is not suitable for small machines, such as small automatic egg frying machines;

[0004] 2. A device specially used for adjusting the posture of the eggs must be set on the conveyor belt, which takes up a lot of space and has high manufacturing costs. Summary of the invention

[0005] (1) Technical issues to be solved

[0006] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a conveyor for automatically adjusting the posture of eggs, aiming to solve the technical problems in the prior art that the egg conveyor has a complex structure and is not suitable for installation in a small space machine.

[0007] (2) Technical solution

[0008] The invention provides an egg posture automatic adjustment conveyor, comprising a conveyor belt and a plurality of freely rotatable egg turning rods fixed on the conveyor belt. When the egg turning rods move to a certain position with the conveyor belt, they can contact active rollers and rotate, and the egg turning rods connected with the eggs rotate synchronously.

[0009] When an egg is placed between two adjacent egg-turning rods, the egg will move synchronously with the egg-turning rods in a relatively stable manner in the groove, and will also be transported along a straight line on the conveyor belt. When the egg moves to the egg-turning rod in contact with the active roller, the egg-turning rod is driven to rotate under the rotation of the active roller, and synchronously drives the egg-turning rod and the egg in contact with it to roll, so that the egg automatically adjusts to a unified posture during rolling.

[0010] (3) Beneficial effects

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The conveyor belt in the present invention has a short conveying distance and is suitable for easy installation in small machinery.

[0013] 2. The present invention provides a freely rotatable egg-turning rod and an active roller. When the active roller drives the egg-turning rod to rotate, the egg can roll accordingly, thereby automatically adjusting the posture of the egg. There is no need to provide a separate adjustment device. The structure for adjusting the egg posture is arranged inside the conveyor belt, which has high space utilization and low production cost.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] like Figure 1 and Figure 2 As shown, the present invention provides an automatic egg posture adjustment conveyor, comprising a conveyor belt 1 and a plurality of freely rotatable egg turning rods 2 fixed on the conveyor belt 1. When the egg turning rods 2 move to a certain position with the conveyor belt 1, they can contact the active roller 3 and rotate, and the egg turning rods 2 connected with the eggs rotate synchronously.

[0025] It should be noted that if Figure 2-4 As shown, the egg-turning rod 2 in the embodiment of the present invention is a hollow roller that is narrow in the middle and wide on both sides. The roller is sleeved on the roller 22, and both ends of the roller 22 are fixed on the conveyor belt 1. The maximum distance between two adjacent egg-turning rods 2 is smaller than the width of the egg. When an egg is placed between two adjacent egg-turning rods 2, since the egg-turning rods 2 are wide on both sides and narrow in the middle, a groove structure adapted to the shape of the egg is formed at the narrowest part in the middle between the two egg-turning rods 2 (hereinafter referred to as the groove). The egg will move synchronously with the egg-turning rod 2 in the groove relatively stably, and since the grooves are on the same straight line, the egg will also be conveyed on the conveyor belt 1 in the same straight line. The present invention is applied to a small automatic egg-frying machine. Keeping the eggs in the same straight line position for conveying can keep the eggs in the same position when entering the next process, avoiding the need to set up another mechanical structure to position and adjust the position of the egg, optimizing the space utilization of small equipment, and saving manufacturing costs.

[0026] It should also be noted that for a large conveyor belt 1, a rack can be set at a certain position in the annular space formed by the conveyor belt 1, and gears are set at both ends of the egg-capsulating stick 2 fixed on the corresponding conveyor belt 1. When the egg-capsulating stick 2 reaches the position where the rack is located, the gear and the rack are meshed, so that the egg-capsulating stick 2 rotates along the conveying direction of the conveyor belt 1, thereby driving the eggs on the egg-capsulating stick 2 to roll and automatically adjust their posture by rolling, but this design is not suitable for use in small equipment;

[0027] Taking a small frying machine as an example, when the conveyor belt 1 and the egg-turning rod 2 convey the eggs in a certain direction, it is usually necessary to stop for a period of time for frying each egg, and then send the next egg after the egg is fried. If the above-mentioned gear and rack structure is used to adjust the posture of the egg, since the egg-turning rod 2 can only roll when the conveyor belt is running, when the conveyor belt stops driving and waits for the egg to be fried, the egg-turning rod 2 located at the rack position remains stationary synchronously, and the small conveyor belt occupies little space and has a short overall length, so the conveying distance of the eggs is also very short. If the eggs are to be automatically adjusted in a very short distance and within a very small number of rolling times, there will be a large error. Therefore, setting a rack in the conveyor belt 1 is not suitable for use in small conveying equipment;

[0028] The present invention sets an active roller 3, which rotates continuously at a certain position. When the egg-turning stick 2 moves to the position of the active roller 3 and contacts and rotates with the active roller 3, the egg in contact with the egg-turning stick 2 is driven to roll. During the time when the conveyor belt 1 stops conveying and waits for the frying of the egg, the active roller 3 can still drive the egg-turning stick 2 to keep rotating. That is to say, when the conveyor belt 1 is stationary, the egg still keeps rolling, so that the posture of the egg is automatically adjusted by using the waiting time. Therefore, the technical solution of the present invention is better than that used in small conveying equipment with limited space.

[0029] The conveyor belt 1 in the embodiment of the present invention is a chain 11 type conveyor belt 1, and a plurality of protrusions 12 are provided on the chain 11. The protrusions 12 are used to fix the roller 22 of the egg-filled egg stick 2. An active roller 3 is provided in the hollow part of the conveyor belt 1. When the egg-filled egg stick 2 fixed on the conveyor belt 1 moves to a position corresponding to the active roller 3, a contact surface is generated between the egg-filled egg stick 2 and the active roller 3. Since the egg-filled egg stick 2 can rotate freely, when the active roller 3 rotates, friction is generated between the contact surface with the egg-filled egg stick 2, thereby driving the egg-filled egg stick 2 to rotate.

[0030] In other embodiments, the active roller 3 can be fixedly installed on the outside of the conveyor belt 1. For example, the active roller 3 can be fixedly set on one side above the egg-turning stick 2 at a certain position, and the contact surface between the active roller 3 and the egg-turning stick 2 forms a transmission, or the active roller 3 can be fixedly set on both sides above the egg-turning stick 2. By generating two contact surfaces, when both sides of the egg-turning stick 2 are simultaneously driven to form rolling, the force is more uniform, so that the rotation of both sides of the egg-turning stick 2 is more stable, driving the eggs on the egg-turning stick 2 to roll stably and automatically adjust the posture of the eggs.

[0031] like Figure 5As shown, when the conveyor belt 1 transports eggs, the egg is placed between two adjacent egg-turning rods 2 and moves synchronously with the egg-turning rods 2 along the conveying direction of the conveyor belt 1. The active roller 3 can rotate clockwise or counterclockwise to drive the egg-turning rod 2 to rotate, so as to adjust the posture of the eggs to be consistent. In this embodiment, the active roller 3 rotates in the clockwise direction. At this time, the egg-turning rod 2 located directly above the active roller 3 is driven to rotate by the active roller 3. Since the active wheel 31 on the active roller 3 and the driven wheel 21 on the egg-turning rod 2 are in friction contact, the driven wheel 21 rotates in opposite directions to the active wheel 31, that is, the egg-turning rod 2 rotates in the counterclockwise direction. Similarly, the egg in contact with the egg-turning rod 2 is driven by the rotation of the egg-turning rod 2, and the rotation direction of the egg is opposite to that of the egg-turning rod, that is, the egg rotates in the clockwise direction. Since the egg is placed between two adjacent egg-turning rods 2, each egg is simultaneously in contact with the two adjacent egg-turning rods 2. When the egg is driven by one of the egg-turning rods 2 to rotate, the other egg-turning rod 2 in contact with the egg will also be driven by the friction generated by the rotation of the egg, and will also rotate in the counterclockwise direction. By analogy, if the potential energy lost by rolling friction during the transmission process is not considered, when the active roller 3 drives one egg-turning rod 2 to rotate, the other adjacent rolling rods 2 in contact with the egg can also rotate synchronously. However, due to the loss of potential energy during the transmission process, the transmission distance driven by friction is relatively short. For small-scale conveying equipment, the number of egg-turning rods 2 for conveying eggs at the same time is relatively small. Therefore, the egg-turning rods 2 with eggs placed on the conveyor belt 1 can be rotated at the same time to adjust the posture of the eggs. Since the eggs are elliptical, during the rolling process, due to the shape of the eggs being narrow at both ends and wide in the middle, the rolling posture will be automatically adjusted to adapt to the grooves formed by the two adjacent egg-turning rods 2, so as to keep the orientation of all eggs on the conveyor belt 1 adjusted consistently.

[0032] It should be noted that the contact surface between the active roller 3 and the egg-captivating stick 2 in the present invention can be set to a friction type or a gear type. In this embodiment, a friction type contact is adopted. Specifically, Figure 3 As shown, the driving roller 3 is composed of two driving wheels 31 and a connecting rod 32 connecting the driving wheels 31. Two driven wheels 21 extend outward from both ends of the roller of the egg-turning stick 2. A bearing 23 is arranged in the driven wheel 21. The egg-turning stick 2 can rotate freely on the roller 22. The driving wheel 31 and the driven wheel 21 are arranged in a corresponding position up and down, and the driving wheel 31 is close to the lower end of the driven wheel 21, and the close position is a friction contact surface. When the driving wheel 31 rotates driven by the motor, friction is generated on the driven wheel 21. Since the egg-turning stick 2 can rotate freely along the roller 22, the egg-turning stick 2 is driven to rotate by the driving wheel 31.

[0033] The conveyor belt 1 in the embodiment of the present invention is provided with an egg storage portion 4 at one end. Figure 6As shown, the lower end of the egg storage part 4 is provided with a swing plate 43, an egg sliding slope 41 and a guide slope 42. Before use, the eggs are placed in the egg storage part 4. The inner wall of the egg storage part 4 and the swing plate 43, the egg sliding slope 41 and the guide slope 42 are combined to form a box shape with a hollow bottom. The hollow part is just aligned with the egg rotating rod 2. A plurality of eggs can be stacked in the egg storage part 4. Figure 6 and Figure 7 As shown, the lower end of the guide slope 42 is aligned with one end of the egg-turning rod 2, and has a vertical downward surface, which can accurately guide the eggs onto the egg-turning rod 2 to prevent the eggs rolling down from the guide slope 42 from hitting the area outside the egg-turning rod 2 to cause the eggs to break. The sliding egg slope 41 is provided to further calibrate the egg falling position, so that the eggs finally fall vertically between two adjacent egg-turning rods 2. By providing the swing plate 43, the eggs in the egg storage part 4 can shake and adjust their positions as the swing plate 43 swings up and down, so as to prevent the eggs in the egg storage part 4 from piling up and getting stuck and not falling, resulting in the egg-turning rods 2 on the conveyor belt 1 running empty.

[0034] The swing plate 43 in the present invention can be driven by a motor or mechanically triggered to swing in a variety of swinging modes. Preferably, Figure 6-8 As shown, the swing plate 43 in this embodiment is tilted, and its upper end is hingedly arranged on the inner wall of the egg storage part 4 through an axle pin 432, and a trigger part 431 is arranged at the lower end. The trigger part 431 in this embodiment adopts a roller that can be lifted up by the driven wheel 21, as shown in FIG. Figure 8 When the egg-turning rod 2 moves in the direction shown in the figure, as the egg-turning rod 2 moves to the position of the trigger part 431 and contacts and lifts up with the trigger part 431, the trigger part 431 drives the swing plate 43 to rotate along the shaft pin 432. Specifically, when the egg-turning rod 2 moves in the direction of conveying eggs, the swing plate 43 is triggered to swing, and the swing plate 43 swings to adjust the eggs in the egg storage part 4 to fall downward between the two adjacent egg-turning rods 2 below, thereby automatically starting the egg conveying. By setting the trigger-type swing plate 43, the use of the driving motor is reduced, the power consumption of the conveyor is reduced, and the use cost is saved.

[0035] The other end of the conveyor belt 1 in the embodiment of the present invention is provided with a counting sensor 5, and the counting sensor 5 includes a paddle 51 and a counter 52. When the egg on the egg spinning stick 2 passes through the paddle 51, since the height of the egg on the egg spinning stick 2 is higher than the paddle 51, when an egg passes through the egg spinning stick 2, the paddle 51 will be moved upwards, and a count will be triggered, and the value on the counter 52 will increase by one; when no egg passes through the egg spinning stick 2, since the height sensitivity of the egg spinning stick 2 is lower than that of the paddle 51, the paddle 51 will not be moved, and thus the count will not be triggered, so the counter 52 will remain. The original number remains unchanged. By setting a counting sensor 5 that can calculate the cumulative number of times the number of times the number of eggs has passed, the number of eggs transported on the conveyor belt 1 can be adjusted, thereby realizing automatic recording of the number of eggs used. An alarm device (not shown in the figure) connected to the counter can also be set. If the counter 52 does not increase in count within a certain period of time, it means that no eggs have been transported on the conveyor belt 1 at this time. The reason may be that the eggs in the egg storage part 4 have been used up or are stuck due to an abnormality. The alarm device sounds to remind the user to check the status of the eggs in the egg storage part 4, and replenish the eggs or resolve the abnormality in time.
