[利用分野及び発明の概要]
本発明は、菓子片の不良品検出方法と、この方法を実施

除去できるようにするものである。Detailed Description of the Invention [Field of Application and Summary of the Invention] The present invention relates to a method for detecting defective confectionery pieces and a defective detection device for implementing this method. If the confectionery piece is maintained in a constant posture within the transport frame and the relationship between the inner circumferential contour of the frame and the outer circumferential contour of the confectionery piece is within an appropriate range, this confectionery piece is judged to be good. If the confectionery pieces are outside the above range, they are discharged outside the conveyance route as defective pieces, so that defective confectionery pieces can be automatically identified and removed.
[従来技術及びその課題]
キャンデイ等の菓子片は、連続的に大量に生産されたあ

、菓子片の単品が大量に生産されると、この後続工程に
おいて、菓子片が個別包装されて一定数量の菓子片が包
装容器内に収容される。[Prior Art and its Problems] Pieces of confectionery such as candies are continuously produced in large quantities and then individually packaged. Therefore, in the confectionery piece manufacturing process, when individual confectionery pieces are produced in large quantities, in the subsequent process, the confectionery pieces are individually wrapped and a certain number of confectionery pieces are housed in a packaging container.
従って、各菓子片が一部損傷しているような不良品、つ

の判断が困難だからであり、判断ミスが生じやすいから
である。Therefore, if a defective product in which each confectionery piece is partially damaged, that is, a defective product in shape, is directly transferred to this packaging process, defective confectionery pieces will be mixed into one packaged product. Conventionally, in order to prevent such inconveniences, defective confectionery pieces have been visually inspected to remove defective confectionery pieces during the transportation process before each confectionery piece enters the packaging process. However, this visual detection of defective products cannot speed up the transportation process. This is because when visually inspecting, it is difficult to judge whether the pieces of confectionery are good or bad while they are moving at high speed, and errors in judgment are likely to occur.

The outline of C) and the conveyor belt (1b) are black images (G
l), Binarize the area outside the contour to become a white image (G2), and use the area inside the pre-stored appropriate contour as a black window,
A method is adopted in which a defect is determined when a certain number of white pixels occur within this window. If this is expressed on the monitor screen as the image output section of the shape difference detection device (3), it will be as shown in FIG. 4. Here, the size of the window (U) is set to be slightly larger than the outline of the actual confectionery piece (C). Therefore, the confectionery pieces (
If C) is partially missing and the amount of white pixels exceeds a certain level, it is determined to be defective. It is also possible to make the size of the window (U) smaller than the size of the actual confectionery piece (C). In this case, all white pixels that occur within the window (U) are defective.

送ベルト(17)の側方に排出するようにしてもよい。The video signal of this camera (2) is compared with the window (U) corresponding to the appropriate contour in the same manner as in the first embodiment to determine pass/fail. (16) The defective product removing device (4) disposed on the subsequent transport belt (17) discharges the defective products to the outside of the transport route. In addition, this defective product elimination device (4) is as follows:
It is possible to adopt the same method as in the first embodiment, but as shown in the figure, the confectionery piece (C) placed on the upper surface of the conveyor belt (17) is moved by the output shaft of the drive means (40). It is also possible to discharge it to the side of the conveyor belt (17).

過後に不良品排除装置(4)を作動させれば良い。In addition, in any of the above embodiments, there is a certain time difference between the timing of photographing by the camera (2) and the timing of operation of the defective product removal device (4), but it is assumed that the confectionery piece (C) is a defective product. In these embodiments, in order to operate the defective product elimination device (4) at a predetermined timing after it is determined that
A delay operation timer may be started by a defective product signal from the shape difference detection device (3), and the defective product eliminating device (4) may be activated after the set time of this timer has elapsed.

ようにしてもよい。In the case of the first embodiment, the number of confectionery pieces (C) conveyed to the position corresponding to the defective product removal device (4) after the time when the output signal determined as a defective product is input is calculated. The counted value is a predetermined number (in this example, "3").
''), the defective product removal device (4) may be activated.

不良品と判定するようにしてもよい。Furthermore, in the above embodiment, pass/fail was determined based on whether a white pixel occurs within the window (U), but the size of the window (tl) is set to be smaller than the outline of the confectionery piece (C). Keep this window (U) and the candy piece (C)
The area between the confectionery piece (C) and the outline of the confectionery piece (C) may be calculated, and if this area is greater than a certain value, it may be determined that the confectionery piece (C) has a defective portion and the confectionery piece (C) is determined to be defective.
