Abstract

PROBLEM TO BE SOLVED: To prevent mixing of a different kind by surely detecting the different kind of a blank of a packaging vessel. SOLUTION: In the case of sack-sticking a blank 1 in a printing mill and carrying it to a food precessing factory, a numeral or the like is apportioned as classification information at every carrier object. A bar code 16 representing the classification information is printed in the overlap width part 10 of the side end of the blank 1. When such a series of processes are performed that the overlap width part 10 of the side end of the blank 1 is turned down to a folding state by e.g. a turning guide 17 in the crease folding part of a sack making machine and then gradually raised to a nearly vertical state by a parallel guide 18 and furthermore returned to the state before being turned down by a returning guide 21, a work is detected by a timing sensor 19 in such a state that the overlap width part 10 is raised nearly vertically. A bar code reader 20 is operated at prescribed timing by receiving a detection signal and the bar code 16 is scanned to read the classification information.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for preventing different types of printed materials from being mixed into printed materials forming a blank of a packaging container.

[0002]

2. Description of the Related Art Conventionally, when a packaging container formed by folding a printed paper blank is used as, for example, an outer box of a food package, a sack that folds the printed blank into a tubular shape and adheres both side ends thereof. It was usual to carry out in a printing factory until the pasting process. And in that case, after holding the blank with the sack on the pressure conveyor, packing it in a box,
Transport to food factory. Then, the contents are filled at the food factory, sealed, and shipped.

[0003] By the way, the outer box of such food packaging is
If the type (spicyness, seasoning, etc.) of the same product is different, or the same product has the exact same pattern, but it is manufactured and filled at multiple manufacturing factories of the food company, so the manufacturer's description In some cases, only the printing of the part is different, and it is not possible to distinguish it at a glance, and if such a thing is mixed, it cannot be removed.

[0004] Therefore, for each factory (manufacturing factory) to be delivered,
By printing blue or red colored balls on the glue margin of the blank, changing the number of colored balls, and reading the number of colored balls with sensors in the sack sticking process at the printing factory, 2. Description of the Related Art It has conventionally been practiced to remove objects and prevent them from being mixed at the stage of packing. In this way, only foods of a particular color ball are delivered for each manufacturing plant of the food company.

[0005]

However, in the above-described conventional method for preventing the mixture of foreign matters by detecting the number of colored balls in the margin portion by a sensor in the sac attaching step, the pasting portion other than the colored ball is not included in the margin portion. In most cases, register marks are printed to match the print register, so it is very difficult to adjust so that only the colored balls are detected and the register marks are not detected. In addition to the possibility of oversight, the detection accuracy is affected by the reflection conditions such as the angle of the glue margin and the distance, and the like, so that different types of products cannot be reliably prevented from being mixed. In addition, it is conceivable to detect by a product-specific barcode that is always printed on the outer box of the food packaging, but in that case, the barcode varies in position, size, etc., making detection uncertain At the same time, if only the product factory is different and the product is the same, the same barcode is attached, so that different type detection is impossible.

Therefore, it has been a problem to surely detect a different kind in a sack-sticking step and prevent mixing.

[0007]

According to the present invention, there is provided a printed matter forming a blank of a packaging container, in which a bar code representing type information is printed on a glue margin.

Further, the detection method according to the present invention provides a method for supplying the above-mentioned mixed-product-prevention printed matter according to the present invention to a box-making machine, folding and gluing, finally folding and bonding the surface of the margin portion. The type information is read by scanning with a barcode reader, and foreign matter is detected.

A bar code mainly represents a number or the like in a black and white pattern. The bar code can be read even if there is a slight variation in the angle and the distance, and the start and stop signals always appear before and after the bar code. Since it is attached, it can be detected without being affected by the register mark or the like attached to another position, and it is possible to cope even when the workpiece moves at high speed. Since the above-mentioned printed material for preventing mixing of different types uses a barcode which has a large tolerance of angle and distance and is easy to cope with speed, a barcode expressing type information is printed on a glue margin part. , In a box making machine,
In the sack-pasting process of gluing, final folding, and gluing, the surface of the folded glue margin is scanned with a barcode reader to read the type information, thereby reliably detecting different types,
Mixing can be prevented. At that time, it is particularly preferable to detect the surface at the folded portion of the glue margin portion after the custom folding in the custom folding process, and by doing so,
Detection can be performed more reliably.
