JPS63153434A - Indicating method for passing inspection of product - Google Patents

Abstract

PURPOSE:To indicate that a product has passed an inspection, by sticking a label with a rejection mark to the product, and erasing its rejection mark by a pass mark same in color as a ground color when the product passes the inspection. CONSTITUTION:A label 1 is stuck to a product 3 whose surface color is black. In such a state, the product 3 is fed out to an inspection process, and whenever it passes an inspection, a pass mark 4 is put by black ink onto a rejection mark 2. In such a way, when all the processes for an inspection are ended, if all the rejection marks 2 are painted out by the pass mark 4, its product is decided to have passed the inspection. If the rejection mark 2 remains, the kind of defect can be discriminated in accordance with its position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for indicating that a product has passed inspection.

[Prior art and its problems]

Generally, several types of inspections are required to determine the quality of a product, and each time a product passes the inspection, a pass mark is placed on the product. Conventionally, this mark of acceptance has been applied by stamping a rubber stamp on the surface of the product, but if the surface of the product is an injection-molded plastic case, the disadvantage is that even if a rubber stamp is stamped, it easily disappears when rubbed. be. In addition, if the product surface is a dark color such as black, it is preferable to use white ink, but there is no suitable white ink, and it is difficult to identify the product even if a pass mark is attached using normal color ink. Furthermore, since the pass mark has a color different from the color of the product surface, it is an eyesore and has the problem of lowering the product value.

[Means for solving problems and their effects]

The present invention provides a method for indicating that a product has passed inspection, which solves the problems of the prior art as described above, and the method includes:
A label with the same color as the surface of the product and a reject mark in a different color than the base color is attached to the surface of the product, and when the product passes the inspection, a label is placed on the reject mark. It is characterized by attaching an acceptance mark of the same color as the ground color.

In other words, with the present invention, a rejection mark is displayed on a label in advance, and when the inspection is passed, the rejection mark is erased by coloring it with ink of the same color as the background color or by pasting a patch on it. It is.

Therefore, when all inspections are passed, there will be no rejection mark and the entire product will have the same color as the surface of the product.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of a label used in the present invention.

This label 1 has a black background and has four white circular rejection marks 2 displayed therein.

This label 1 is attached to a product 3 whose surface color is black as shown in FIG. In this state, the product 3 is sent to the inspection process, and as shown in FIG. 3, every time the product passes the inspection, a pass mark 4 is added on top of the fail mark 2 with black ink. When all the inspection steps are completed in this way, if all the reject marks 2 are covered with pass marks 4, the product is passed. If the rejection mark 2 remains, it is possible to determine what is defective based on its position.

Marking of acceptance is performed as shown in FIG. 4, for example. In other words, the inspection machine 5 performs a continuity test and parts inspection on the product 3, and when it passes, it sends a signal to the air cylinder 6, which operates to move the rubber stamp 7 with black ink forward, thereby identifying the part that has failed. Fill in mark 2 with passing mark 4. When all the inspections are completed in this way, as shown in FIG. 5, a photoelectric switch 8 is used to detect the presence or absence of a white rejection mark 2 and, if present, its position, and a comprehensive judgment is made.

〔Effect of the invention〕

As explained above, according to the present invention, a label with a rejection mark is attached to the product, and when the product passes, the rejection mark is erased with an acceptance mark of the same color as the background color, so that ink is removed. This system has the advantage that even products that are difficult to ride, or products that are colored in dark colors such as black, can be clearly marked as pass or fail, and automatic inspection can be performed reliably. In addition, the background color of the label is the same as the color of the product surface, and the color of the pass mark is also the same, so when the pass mark is attached, the entire color is almost the same, and the pass mark becomes an eyesore. This also prevents a decline in product value.
