Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an air chamber detection device in a "packer" for packing eggs into "bags".

As shown in FIG. 4, the chicken egg 1 exhibits a so-called egg shape in which one radius of curvature in the longitudinal direction is large and the other radius of curvature is small,
Further, in the cross-sectional view, there is an air chamber 2 inside the shell on the side with a larger radius of curvature, an egg yolk 3 near the center of the entire length, and an egg white 4 around the yolk 3.

With this structure, when the chicken egg 1 is placed horizontally, the center of gravity of the egg is near the center of its entire length, so the center comes into contact with the plywood 5. Therefore, the position where the chicken egg 1 contacts the plywood 5 is biased towards the smaller outer circumference than the maximum outer circumference position on the side surface of the chicken egg 1. Therefore, when the chicken egg 1 is rotated on the inclined plate surface, the chicken egg 1 rotates while being bent toward the side with the smaller radius of curvature, as shown in FIG. In other words, the egg 1 that is in contact with the plywood 5 is in contact at two points on the side of the egg 1, a point with a large outer periphery and a point with a small outer periphery. It deviates. This invention is a "chicken egg air chamber detection device" created by utilizing the properties of the chicken egg 1.

Conventionally, when packing chicken eggs in plastic cases, if the air chambers inside the eggs are not packed upwards (that is, with the smaller radius of curvature of the eggs facing downwards), the eggs become unable to breathe, which inevitably leads to The difficulty that led to the loss of freshness was impossible.

That is, in the conventional air chamber detection device, as shown in FIGS. 6 and 7, two "bars" 6, 6a with "R" are arranged in parallel with a certain distance maintained, and one of them is Since the "bar" 6 is movable in the direction of the arrow 7, when the "bar" 6, 6a holds the chicken egg 1, the bar 6, 6a
When the distance between the eggs 1 and 2 becomes narrower and the maximum outer periphery is sandwiched between them, the side with the smaller radius of curvature will be downward due to the position of the center of gravity of the chicken egg 1, and the air chamber 2 will be oriented upward. However, this method has the drawback of crushing and damaging the eggs, which are strong against vertical pressure but weak against horizontal pressure. The present invention provides a device capable of crushing a chicken egg 1 and detecting the air chamber 2 of the chicken egg without damaging the egg.
It is an object of the present invention to provide an air chamber detection device for chicken eggs that has an extremely simple configuration and can quickly and efficiently pack a large number of chicken eggs in a plastic case with the air chambers facing upward.

The invention will now be described with reference to the embodiments shown in the drawings.

As shown in FIGS. 1 to 3, a drive device (not shown)
The two loafs 9, 9 rotating in the same direction are arranged in parallel.

The distance between the eggs is sufficient to allow the egg to be placed on the rollers 9, 9 with the longitudinal direction of the egg facing in the direction of the vertical line of the rollers 9, 9, as shown in FIG. The egg feeding device 8 is provided on the two rollers 9, 9, and the roller 9
, 9 are equipped with shooters 10 at the left and right ends, respectively.
The eggs 1 are fed from the egg feeding device 8 onto a pair of loafs 9, 9 which rotate in the same direction at regular intervals.
The rollers 9, 9 have a roller core 9a as shown in FIG.
The periphery of the egg 1 is covered with an elastic body 9b to have the function of protecting the chicken egg 1 and the function of completely rotating the chicken egg 1 by the rotation of the rollers 9, 9 without breaking it. When the pair of rollers 9, 9 rotate in the same direction, the egg 1 on the rollers also rotates at the same time, and advances toward the smaller curvature.

The principle is the same as that described above, as shown in FIG. 5, when a chicken egg rotates, it always rolls toward the side with the smaller radius of curvature. That is, the plywood 5 is rolled up and rolled with rollers 9,
9 is formed, and instead of the egg itself rotating, the rollers 9 rotate to rotate the egg 1. Therefore, the egg 1 moves on the rollers 9 in the direction of the smaller radius of curvature. In other words, when the smallest part of the radius of curvature of the chicken egg is facing left, the egg will move to the left.
If the vehicle is facing right, proceed to the right. 1 and 2 show the case where the chicken egg 1 is placed so as to move to the right. The egg 1 will move in the same way regardless of whether the direction of rotation is clockwise or counterclockwise. In this way, the egg feeding device 8 moves to the left or to the right depending on the orientation when it is placed on the rollers 9, 9.
9, and by means of shooters 10, 10 provided at both ends of the rollers 9, 9, the one with the smaller radius of curvature is turned down, and falls while maintaining the position of the air chamber 2 upward, and the plastic It is received and housed in the case 11 above the air chamber 2. In this way, no matter which direction the chicken egg 1 is placed on the rollers 9, it will move in the direction with the smaller radius of curvature, and the air chamber 2 will be directed upward by either the left or right shooter 10. In this case, it can be packed in a plastic case 11. As described above, this invention arranges two rollers 9, 9 that rotate in the same direction in parallel, and provides an egg feeding device 8 above the rollers 9, 9. Since the air chamber detection device for eggs is constructed by attaching shoes 10 and 10 to both ends of the lo-fu, the mechanism is extremely simple and can be provided at a low price. It can be packed in a plastic case with the air chamber facing upwards.
Packing efficiency is extremely good and quick, and since eggs are not compressed by two bars unlike known methods, eggs are less likely to be compressed and damaged.

Furthermore, when the elastic bodies 9b on the surfaces of the rollers 9, 9 are constructed by providing roller cores inside each, the eggs are further protected, the eggs can completely rotate on the rollers without rolling, and the progress of the eggs can be prevented. It also has the effect of being quick and smooth.
