Definitions
- a proposed solution is described in the international patent application PCT/NL96/00049.
- a head with drive motor for rotating a beer bottle is herein placed on a carrousel and, using a CCD camera, a number of images are recorded by the CCD camera after the rotation movement has been interrupted, and these images are analysed using image processing techniques.
- a drawback of this method is that a drive motor and camera must be arranged for each carrousel position in order to enable the inspection of for instance 60,000 bottles per hour.
- the present invention provides a method for inspecting packagings for liquid medium, such as glass bottles optionally filled with beer or other drink, wherein the packagings are moved in line at predetermined speed and/or predetermined mutual spacing, and wherein images of the packagings are recorded by a number of cameras disposed adjacently of or successive to each other, and these images from the different cameras are combined in order to detect foreign substances therein.
- the beer bottles are rotated and stopped. It is also conceivable, in any case theoretically but perhaps also practically, for movement of the liquid relative to the bottle to take place in a different way, for instance by causing the bottle to take a sharp bend one or more times at high speed.
- This known device comprises a carrousel in which the bottles are clamped and wherein a camera is placed for each position.
- the- cameras being placed separately of the carrousel while the bottles move along in front of them.
- the bottles are transported in line and brought to pitch, rotated and stopped during the inline transport.
- images can then be obtained of a packaging which are processed via a multiplexer, for instance subtracted from each other after some pre-processing, in order to enable detection of damage or loose particles such as glass splinters therein.
- the present invention further provides a device for inspecting packagings, comprising:
- - a number of cameras disposed along the line for recording images of the packaging; and - a video-multiplexer to which the cameras are connected for the purpose of processing the successively obtained images of a packaging.
- the bottle packagings are rotated slowly along the cameras, for instance for recognition of the labels on the bottles.
- Fig. 1 shows a partly schematic view in perspective of a preferred embodiment of the present invention
- Fig. 2 shows a side view from another angle of another embodiment according to the present invention.
- Fig. 3 shows a block diagram of an embodiment shown in fig. 1 and 2.
- a number of beer bottles Bl, B2, B3 ... Bll is supplied on a feed conveyor 1, whereafter bottles B6-B11 are brought to pitch in a first part 2 of the preferred embodiment 3 of the present invention.
- conveyor belts 4, 5 Arranged on either side in this part 2 are conveyor belts 4, 5 to also cause the relevant bottles to rotate.
- Light sources 21, 22, 23, 24 and 25 are situated under the bottles at which the cameras are directed. The cameras are directed at an angle of about 45° to the bottom of the bottles. In a preferred embodiment (not further shown) light sources 21-25 can be combined into a single light source.
- a number of central processing units are connected to video- multiplexer 16 to process a series of images of a bottle recorded by the cameras, and wherein the correct image is coupled to the correct product by making use of the video-multiplexer.
- CPUs central processing units
- so-called intelligent cameras can be applied, wherein a part of the processing takes place at the camera, and wherein images are then for instance transferred from the one camera to the other without the intervention of a CPU.
- the distance D between two cameras is as small as possible, for instance 10 cm, due to the size of the products. If there are ten cameras this will produce a length of the image system of 1 m and a minimal line speed of 2. m per second. A number of images corresponding to the number of cameras is recorded of each product. Operation can take place at a shutter speed of for instance 200 msec.
- each product there is recorded a number of images corresponding for instance with the number of cameras.
- a starting point can for instance be taken 50 images (frames per second, or 100 fields) .
- the images or fields must overlap or not, depending on the size of the camera and on the distance from the camera to the images of the packagings for recording.
