Abstract

PURPOSE:To automatically and simply recognize various types of packages by making a printed board itself contain the codes to automatically recognize the packages without attaching the bar code labels. CONSTITUTION:The code corresponding to the type of a printed board 1 is turned into a binary code at a designated position of the board 1 in a production process of the board 1. A pierced hole 2 is set at a position corresponding to '1' and no pierced hole is prepared at a position corresponding to '0' respectively. When a package code is read, a light emitter 3 and a light receiver 4 are set at the designated positions of the panel 1 so that this panel 1 is held between the emitter 3 and the receiver 4. The light beams 5 sent from the emitter 3 are transmitted through the holes 2 of the board 1 and these transmitted beams 6 reach the receiver 4. The receiver 4 transmits the signals to a decoder 7 to show the number of holes 2 and the presence or absence of the corresponding beams 6. Then the decoder 7 converts these received signals and detects the binary codes of the board 1. In such a way, various types of packages an be recognized.

Description

[Detailed description of the invention] [Industrial application field] The present invention is package manufacturing and processing using automatic inspection machines.

This invention relates to a package code recognition method that automatically recognizes the type of product package being inspected.

[Conventional technology]

Conventionally, this type of package code recognition method recognized the package code by using a jig compatible with the product package or by reading a barcode label affixed to the product package with a barcode league.

[Problem to be solved by the invention]

The conventional package code recognition method described above requires a jig for product packaging or a process of pasting a barcode label on the package, so it is not necessary to use a jig or a barcode reader that can read the code unattended. It has the disadvantage of being expensive.

[Means to solve the problem]

The package code recognition system of the present invention includes through-holes in which codes for each package are binary-encoded at predetermined positions on a printed circuit board, detecting means for detecting the number and position of the through-holes, and detecting means for detecting the number and position of the through-holes. It is characterized by comprising a converting means for converting the output signal of the detecting means into a binary code.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1(a) is a block diagram showing an embodiment of the package code recognition method of the present invention, and FIG. 1(b) is a block diagram showing an embodiment of the package code recognition method of the present invention.
) is a plan view showing an example of a printed board in FIG.

As shown in FIG. 1(b), at the specified position of the printed board 1, a code corresponding to the type of printed board is encoded in binary, such as ""l 010°', at the manufacturing stage of the printed board 1.
A through hole 2 is provided at the position corresponding to ``1'', and 0゛'
No through holes are provided at positions corresponding to . When reading the package code, place the light emitting device 3 at the specified position on the printed board 1 across the printed board 1 as shown in Figure 1 (a).
and a light receiver 4 are arranged. The light 5 emitted from the light emitter 3 passes through the printed board 1 only where the through hole 2 exists, and the transmitted light 6 reaches the light receiver 4. The light receiver 4 sends a signal indicating the presence or absence of passing light 6 corresponding to the number of through holes 2 and the hole position to a decoder 7.
The decoder 7 converts this signal to detect the binary encoded code of the printed board 1.

In addition, in Fig. 1(b), if the arrangement of the through holes 2 is about the size of a 16-pin DIPIC, the maximum is 2" = 65,5
It is possible to recognize 36 types of packages.

In this embodiment, the number of through holes and the hole positions are detected optically, but mechanical detection means may also be used.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to automatically and easily recognize many types of packages by having a code for automatic package recognition on the printed board itself without pasting a barcode label. It has the effect of being able to.
