In view of such an actual state, the present invention is characterized by devising a technique that emit light to emit light penetrating eggs being transported on a transport roller by using a light source, and generates an image of the eggs irradiated with light using a camera, and determines abnormalities of the eggs through image-processing that runs on a computer so that the eggs can be separately discharged.

Description

Abnormality eggs detector

The present invention relates to a new concept of technology for concisely and error-free detection of abnormal eggs (blood eggs, wrinkled eggs, rotten eggs, etc.)

Eggs are one of the complete foods that contain a large amount of essential amino acids necessary for growth, such as lecithin, iron, phosphorus, and vitamin A.

The quality of these eggs depends on whether they contain foreign substances internally or whether they are rotten, the types of internal foreign substances include meat and blood spots, and externally, the quality of eggs is absolutely dependent on whether or not cracks occur.

Among the foreign substances, blood spots are generated by the blood of chickens entering the eggs during the egg formation process. It is one of the most influential factors in consumer purchasing.

Such blood ovulation occurs when an egg yolk ovulates from the ovary. It occurs at any time due to stress or environmental factors, and it is difficult to visually identify and select it before the product is released because the external crack is microscopic.

As a technology for detecting blood eggs, that is, as equipment for identifying blood inside eggs, it is possible to analyze the red color among white eggs using a halogen lamp for visible light. In the case of eggs, brown eggs and hemoglobin color are similar, so it is often not possible to distinguish between normal eggs and eggs with blood.

As a prior art for detecting such blood eggs, Patent Registration No. 1410972, a blood egg detection system capable of examining blood eggs of various sizes/names is disclosed.

The prior art detects blood eggs using a spectroscopic analysis device, but can control the direction and position of irradiating and receiving light according to the size, type or location of the egg to be tested, as well as irradiating light by avoiding the pores of the egg. It is characterized in that it can test blood eggs of various sizes.

The prior art detects blood eggs by analyzing the spectrum of light received from the light receiving means after irradiating light from the light source module to the eggs being transported. The most effective method is image processing of an egg (subject) irradiated with a light source using a camera.

However, in the prior art, as the eggs are transferred in a fixed state to the pocket-type picker formed in the transport chain, the entire part of the egg cannot be image processed even if the camera is used, but only the part illuminated by the camera has no choice but to image processing limitedly. The problem is that the detection is not precise.

As a means for solving the above problems, the present invention uses a light source to irradiate light passing through an egg being transported on a transport roller, and also uses a camera to generate an image of an egg irradiated with light, and then image it on a computer. The purpose of this is to develop a technology that determines whether an egg is abnormal through processing and separates and discharges it.

In addition, in the present invention, while the egg passes through the image processing section in which one or more cameras are installed, one or more cameras can process the egg seamlessly while temporarily rotating the egg in place while the transfer roller exerts rotational force. The purpose is to develop the technology to make it possible.

In addition, the present invention is a technology that allows a drawer-type pedestal on which a light source module is mounted on which a plurality of light sources are fixed can be removed and inserted between the upper and lower transfer rollers along the guide rail installed through the front and rear plates of the detector body. purpose of salvation.

In addition, an object of the present invention is to devise a technique for inserting a protective glass drawer with a protective glass installed on the upper portion of the drawer-type pedestal through a guide rail installed through the front and rear plates of the detector body.

According to the present invention, abnormal eggs (blood eggs, wrinkled eggs, rotten eggs, etc.) It provides the effect of reliably separating without error.

In addition, while the egg passes through the image processing section in which one or more cameras are installed, the egg is temporarily rotated in place, and one or more cameras repeatedly generate images to process the entire part of the egg thoroughly to detect abnormal eggs. It provides the effect of more precisely and efficiently.

Moreover, the light source module is installed on the drawer-type pedestal, and the drawer-type pedestal can be easily removed and inserted, providing the effect of improving the convenience of cleaning and maintenance.

In addition, by installing a protective glass drawer on the upper part of the drawer-type pedestal, it is not only safely protected by preventing broken eggs or various foreign substances from falling into the light source, but also preventing malfunction of the light source, and the protective glass drawer is easily removed Because it can be inserted, it provides a very high effect of convenience in cleaning and maintenance.
