JP3025581U - Imaging method by color line sensor of device for discharging defective empty bottles that progress at high speed - Google Patents

Abstract

(57) [Summary] [Purpose] To image the entire circumference of a bottle that runs at high speed (4 m / sec) by detecting the cracks, cracks, scratches and foreign objects and discharging the defective product. [Structure] Four bottles for the body of the bottle, four nozzles for the mouth, and one nozzle for the bottom are arranged, and the bottle is imaged straight upright. [Effect] By implementing the PL method, an inspection machine is a necessary condition in the bottle sales industry, and the industry demand is great.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a method for inspecting empty bottles after cleaning and before filling.

[0002]

[Prior art]

 It was detected by visual inspection or rotation.

[0003]

[Problems to be solved by the device]

 The conventional method of visual inspection and the method of rotating the bottle to take an image with an area sensor and detecting it by image processing cannot achieve high speed and are often overlooked. Therefore, speeding up and eliminating oversight are problems.

This device simplifies the conventional weaknesses and handling, and instead of capturing the difference in bottle diameter with a single camera, a separate image capturing system is created for each different diameter, and cracks, cracks, and foreign objects occur with the jaspin. The purpose is to detect dirt.

Since the image is picked up by one area sensor, the focus is off between the mouth and the body, and it is difficult to detect.

[0006]

[Means for Solving the Problems]

 In order to achieve the above cause and purpose, the structure of the present invention moves the bottle straight, images the entire circumference from four directions, and images the narrow part of the mouth from four directions. The bottom is a means to take images individually at the bottom with each jaspin so that defects can be detected without lowering the detection accuracy.

[0007]

[Action]

 In FIG. 1, the bodies 1 to 4 capture images from four directions as shown in FIG. Since it is not a print inspection, there is no need to correct the passing speed difference. Next, in order to make the jaspin, as shown in FIG. 3, even the mouth portion can capture an image with the color line sensors of the mouths 1 to 4 to capture a subtle abnormality. As shown in Fig. 4, the bottom part can also capture images with a dedicated color line sensor.

A feature of the captured image can be extracted by conventional image processing to remove defects.

[0009]

【Example】

 As shown in Fig. 1, it is used as an image input device for inspecting the entire outer surface of a bottle that travels straight at high speed.

[0010]

[Effect of device]

 By implementing the PL method, inspection equipment is a necessary condition in the bottle sales industry, and the industry is in great demand.
