JPS6089720A - Enclosing method of weight indicating color mark in egg container - Google Patents

Abstract

PURPOSE:To discriminate a weight classification accurately by providing a colored string body for tearing off added to the connection part for swinging opening/closing fulcrum constitution between the main body and lid body of each container, and detecting the color by a color sensor. CONSTITUTION:The container 5 is vacuum formed so that the main body 5A and cover body 5B each having ten egg storage recessed parts 5a and 5b are connected in a free opening/closing state along one long side as a fulcrum. The string body 9 is formed at the connection part 5c previously by thermocompression during the formation of the container, painted in one of four colors for weight classification and separates the main body 5A and cover body 5B treated in a closed state by tearing off by gripping and drawing the projection part 9a at one terminal side. The sensor detects the color of the tearing string body 9 of each container 5 to discriminate the weight classification.

Description

[Detailed Description of the Invention] The present invention enables buyers and others to know at a glance how much the weight (unit weight) of eggs that are the contents is when displayed and sold at a supermarket, etc. It is a method of enclosing a weight-specific cuckoo mark in the egg container, which is standardized (Agriculture, Forestry and Fisheries Packed Egg Standard), to be enclosed in the egg container so that it can be seen. While continuously and irregularly transferring an open container containing a plurality of eggs for each sorting stage, it is determined which of the aforementioned weight-based sorting stages the container being transferred is in. , based on the discrimination results, insert a plurality of preset crow marks into each container corresponding to the aforementioned classification stage,
Thereafter, the present invention relates to a method of enclosing weight-specific force marks into egg containers, in which the lumber body and lid of each container are closed.

The most important thing in carrying out the above method is to ensure that the mark is placed in the corresponding container. Accuracy is required in determining which of the weight classification stages described above. Conventionally, as such an accurate table determination means, the number of holes formed in advance corresponding to the above-mentioned classification stage is generally used to determine the number of holes that are connected to the body and lid of each container for configuring the swinging opening/closing point. A method was used to determine the difference by reading the
'The present invention overcomes the above-mentioned drawbacks of the conventional method, which had the disadvantage of requiring a separate drilling process that is unnecessary in view of the original function of the egg container when manufacturing (molding) the egg container, and contributing to an increase in the cost of the container. The purpose of this invention is to propose a method that can easily and accurately perform the above-mentioned discrimination by effectively utilizing the structure attached to the container in order to facilitate the removal of rabbits housed in the container. has.

In order to achieve the above purpose, the egg container according to Oki's invention
The method of enclosing color marks according to weight is to distinguish the classification stage according to weight for the transfer container by attaching a cut-out mark attached to the connecting part for configuring the swing opening/closing fulcrum of the body and lid of each container. This method is characterized in that the striatum is color-coded according to the weight and classification stage of the egg, and the color is detected by a cup sensor to perform discrimination.

To greatly simplify and facilitate the opening of containers that have been strongly sealed by means such as heat sealing, as a discrimination medium for classifying containers by weight for containers that are continuously or irregularly transported. Since it effectively utilizes the striped strip attached to the joint that forms the swinging opening/closing fulcrum between the container body and the lid, and detects its color with a non-contact color sensor, it is easy to use. There is no need to incorporate into the container manufacturing process the process of obtaining a structure just for the above-mentioned discrimination, and the desired discrimination can be made by using a rational means that utilizes a structure that makes it convenient for consumers etc. to take out the eggs from the container. It has now become possible to do this with great accuracy and ease.

An embodiment of the method of the present invention will be described in detail below with reference to the drawings.

The belt conveyor (container alignment section IT, which is shaped like a square in plan view for arranging the containers 161 in a vertically long position and moving them one by one) is formed in the middle of the container transfer path by the belt conveyor 61. Immediately downstream of alignment 5 (71), there is a sensor 1g+ that automatically determines whether the containers [Art 1] are in the LL, L, M, or MS classification stage according to weight, which are transferred in a vertically aligned posture. is set up.

As shown in FIG. 2, each container has a body (5mm) and a lid (5B) each having a total of 10 egg storage parts (5&) and (5b).

Based on the discrimination result by the cutter sensor (81), the tray is preset in each container +ril in accordance with the above-mentioned identification step, and four-colored cutler marks (lla) (lll) are placed in each container.
