Description

A novel transition is carried device for birds, beasts and eggs fractional packaging

Technical Field

The invention relates to the technical field of preliminary processing of eggs, and further relates to egg weight grading packaging equipment, in particular to a novel transition conveying device for grading packaging of eggs.

Background

At present, domestic equipment manufacturers independently process grading and supporting, and the egg grading equipment and the egg supporting equipment are two sets of equipment. On the premise of no support, the general independent grading equipment can directly discharge eggs on the conveying belts with corresponding weight grades after multi-row grading, a large amount of labor is consumed for picking up the eggs, and the independent support equipment is complex in structure, slow in speed and incapable of grading the weight of the eggs. The independent tray loading equipment is simply and roughly connected to the conveying belt of the graded egg discharging port, the graded tray loading integration can be realized, but the efficiency of the independent tray loading equipment is limited, and the overall efficiency is lower. The independent egg tray loader is high in price, and after the complete machine is formed, each grading channel needs to be connected to the independent egg tray loader, so that the complete machine is high in price. In order to organically combine the grading equipment and the support equipment, eggs conveyed in multiple rows need to be conveyed in a single row, the grading weighing precision can be improved due to the low speed of the eggs conveyed in multiple rows, the eggs which are converted into the single row and then adjusted in posture can easily and quickly enter the support machine, and the structure of the support machine can be further simplified, so that the cost is reduced. Therefore, the transition device for changing multiple rows of poultry eggs into single row can organically combine grading and packaging, ensure the high-efficiency and stable operation of the whole machine and reduce the cost.

In the field of graded packaging of eggs, since foreign enterprises have started to accumulate the technology in the field for many years earlier, several foreign companies master the graded packaging integrated technology of eggs. Foreign companies adopt a clamping jaw mechanism on a transition scheme of changing a plurality of rows of poultry eggs into a single row and a single row egg carrying conveying device. For example: the Dutch MOBA company uses a reciprocating push rod device to transfer eggs into a single-row egg carrying conveying device adopting a clamping jaw structure in a multi-row to single-row transition mode; the Japanese consortium machine adopts a multi-row to single-row transition device with a clamping jaw structure to feed eggs to a single-row conveying device with a support-shaped structure. One of the two devices of the foreign equipment, namely the multi-row to single-row transition and the single-row conveying, is necessarily in a clamping jaw structure. The opening of the clamping jaw structure is fixed, small eggs cannot be clamped, and too large eggs cannot enter, so that the clamping jaw structure is suitable for eggs with small appearance difference. At present, the eggshells of a plurality of egg varieties in China are very thin, and the damage rate of the thin-shell eggs by the clamping jaw structure is increased. In addition, domestic demand for duck eggs is increasing day by day, especially salted duck eggs and preserved eggs, so domestic requirement duck eggs, preserved eggs and eggs do the same processing and need to be put in the palm in grades, and the clamping jaw mechanism is not suitable for use because of the great difference of the appearance size of duck eggs.

In the whole process, eggs conveyed in a plurality of rows move at a lower speed all the time, the single-row egg conveying and loading device moves at a constant speed and a high speed all the time, and the 9 transition device moves at a variable speed under the action of the cam.

After the eggs are subjected to size adjustment and weight weighing, the eggs are positioned in the position shown in fig. 19, the small ends of the eggs face right, the large ends of the eggs face left, the eggs fall into the 9 transition device after passing through the 192 overturning guide rail, the eggs fall into the 9 transition device in an upward inclined mode due to the special structure that one end of the 192 overturning guide rail is long and the other end of the 192 overturning guide rail is short, and the whole falling process is shown in fig. 20.

In fig. 20, a is the initial state and b is the egg falling state, and when the egg enters the 9 transition device, the egg will be in the state of fig. c after entering the 9 transition device because the 6 transition element egg receiving groove is funnel-shaped. The process of entering 9 the transition device is shown in fig. 21.

When eggs do not enter, as shown in the state of the figure a, the egg receiving assembly 2 on the left side and the egg receiving assembly 2 on the right side are both in contact with the lower limiting rod 31 under the action of the counterweight iron block 22, and when eggs enter, as shown in the state of the figure b, because the weight of the eggs is heavier than that of the counterweight iron block 22, the egg receiving assembly 2 rotates around the long opening and closing rod 41 and the short opening and closing rod 51 until the egg receiving assembly 2 is in contact with the upper limiting rod 32, the whole entering process utilizes the lever principle to buffer the eggs entering the transition device 9, and even eggs with thin eggshells can be treated leisurely.

In the process 8, the transition driving assembly enables 9 the transition device to be in a static waiting state through the cam. After eggs completely enter the 9 transition devices (figure 22a), the 8 transition driving assembly controls the 9 transition devices to move towards the right (figure 19 right hand direction) in an accelerating mode through the cam, when the rightward movement speed of the 9 transition devices is equal to the speed of the single-row egg conveying and carrying devices, the single-row egg conveying and carrying devices are located right above the single-connecting grooves of the 9 transition devices (figure 22b), then the 9 transition devices and the single-row egg conveying and carrying devices do constant-speed following movement, when the 9 transition devices continue to move towards the right, the guide rails are opened and closed 92, the egg receiving grooves of the 9 transition devices are opened, the eggs enter the single-row egg conveying and carrying devices (figure 22c), after the eggs enter the single-row egg conveying and carrying devices, the 9 transition devices decelerate until the speed is zero, the eggs immediately return to wait for the next row of eggs, and the operation is repeated in such. The specific process is as shown in fig. 22.

After passing through the 9 transition devices, the poultry eggs enter a single-row egg loading device and then enter a tray loader.

When the egg carrying device conveys the eggs to the corresponding positions to be released, the egg carrying device can be opened after the action of executing devices such as a rotary electromagnet or an air cylinder and the like, so that the eggs enter the tray loader.
