Definitions
- the present invention relates to a device and a method for inspecting closed containers. It is known in the prior art that containers are filled with a liquid and then sealed with closures. These closures are usually screwed onto the respective container.
- the closure is usually applied directly after the filling process.
- the container should then be sealed gas and liquid tight.
- checking the closure for correct seating and thus implicitly checking the tightness of the sealing system represents an essential quality assurance measure.
- Various methods and devices are known for the case of leaks between the opened screw closure and the container.
- a cap seat check is carried out by means of a camera from the side using a transmitted light method.
- the distance between the upper or lower side of the closure or the safety ring and the mouth of the container is measured, for example using a support ring for PET bottles.
- two views offset by 90° or 3 views offset by 60° or 120° are usually used, as well as imaging through a telecentric lens.
- a shutter-angle of rotation detection by means of a camera in the horizontal direction and using incident light illumination is also known.
- This recognition uses image processing or optical sensors to search for the position of an angle-determining feature on the closure and a feature on the outside of a container that is usually transported in any rotational position, and thus monitors the decisive parameter distance between the two markings for the tightness of a closure.
- the support ring at the lower end of the mouthpiece of a typical plastic still water bottle is increasingly being kept very small, so that it can hardly or no longer be seen from above under the closure. It is also known to completely save the support ring. Therefore, detection of the angle of rotation of the closure, in which the angular position of features on the closure and the support ring is viewed from above and evaluated, can no longer be used here.
- the present invention is therefore based on the object of providing a container closure check for containers which, on the one hand, works very precisely and, on the other hand, can also be used with containers which dispense with carrying rings or largely save on them.
- a device according to the invention for treating containers has a transport device, which transports the containers along a predetermined transport path, and a filling device, which fills the containers with a free-flowing and in particular liquid medium, and a closing device, which attaches closures to the filled containers and in particular screwing these closures onto the containers. Furthermore, an inspection device is provided, which is arranged after the closing device in the transport direction of the containers, and which inspects the containers with the container closures arranged thereon, the inspection device having an illumination device which illuminates the container to be inspected and an image recording device which is suitable and intended for recording spatially resolved images of the containers.
- the image recording device is at least also aligned with areas of the containers which are arranged in a longitudinal direction of the container below the container closures arranged on the containers, and a viewing direction of the viewing device encloses an angle of more than 20° with the longitudinal direction of the containers in such a way that that at least one marking applied to the container can be detected by the image recording device.
- This angle thus designates the angle of the camera axis to the bottle axis or container axis.
- an evaluation device which, from an image taken of the container provided with the marking, determines a relative rotational position of this container in relation to the container closure arranged on the container. In particular, a rotational position with respect to the longitudinal direction of the container is determined. From the rotational position it can in turn be determined whether the closure is properly arranged on the container.
- the rotary position of the cap relative to the container is linked directly to the vertical position of the cap above the container mouth via the pitch of the thread. If the ideal height deviates from a specified amount, the tightness of the seal cannot be guaranteed and the container must be considered to be inadequately sealed.
- the container closure preferably also has a marking which indicates the rotational position of the closure with respect to the longitudinal direction of the container.
- the above-mentioned angle of the viewing device with respect to the longitudinal direction is particularly preferably greater than 30°, preferably greater than 40°, preferably greater than 50°, preferably greater than 60° and particularly preferably greater than 70° and preferably more than 73° (compared to the longitudinal direction).
- a horizontal or almost horizontal angle (i.e. 90° compared to the longitudinal direction) of the Camera is beneficial for inspection.
- An opening angle of the image recording device or of a lens is preferably selected in such a way that the closure is completely captured.
- the optimum angle of view can vary. If the image recording device or camera z. B. 200 mm away, then a 28 mm shutter takes up an angle of view of 8 °.
- closures are in particular closures screwed or screwed onto the container or the mouth.
- closures are screwed onto an external thread of the container.
- the containers are particularly preferably transparent or translucent.
- the containers are preferably plastic or glass containers.
- the lighting device has a large area.
- the lighting device can emit both diffuse and directed radiation.
- the lighting device can be arranged telecentrically.
- the container or the area to be inspected is particularly preferably located between the lighting device and the image recording device. This means that the inspection is particularly preferably carried out using the transmitted light method.
- the image recording device is particularly preferably directed at an unfilled area of the container, that is to say in particular at an area in which no liquid has yet been arranged inside the container.
- the markings on the container are also advantageously arranged in a neck area of the container, for example below a support ring but above the normal liquid level, preferably directly below the support ring or closure in containers without a support ring, since this area is least stretched during the stretch blow molding process. This is usually the neck area of the container, which is directly below the mouth.
- This area is particularly suitable for observing the markings attached to the container, since the image recording is not disturbed by the liquid inside the container and there is no medium or filling product in front of or behind the markings.
- the marking can thus be recognized more reliably and in a significantly larger angular range around the container axis than at the level of the product due to its light refraction properties.
- Said features or markings on the container can consist, for example, of clear structures applied one or more times next to one another and in particular vertical structures, ie structures running in the longitudinal direction of the container, which can be reliably recognized even under unfavorable conditions.
- a preferred embodiment requires several views so that the features can be reliably recognized in at least one view.
- the observation is a view from the side, a view from the side being understood here as a viewing direction of a camera essentially from a horizontal direction (with the container being in a substantially vertical longitudinal direction) with a predetermined elevation angle will.
- Transmitted light or transmitted light observation is understood to mean that the containers are transparent or translucent and that appropriate lighting is fitted on the side of the observation area opposite the camera.
- any disruptive structures that may be present on the rear wall can also be visible, measures can also be taken, such as observing the container from a slightly offset horizontal direction (see above). that the rear wall is displayed in a different height position in the camera image).
- at least one marking applied to the container closure can be detected by the recording device. A relative rotational position between the closure and the container can be deduced from the detection of this marking on the closure and also the marking on the container.
- the evaluation device therefore preferably determines the relative rotational position of this container in relation to the container closure which is arranged and in particular screwed on the container from an image recorded of the closure provided with the marking.
- the device preferably has a processor device which, on the basis of the rotational position determined, determines whether the closure is correctly arranged on the container.
- the evaluation device determines a rotational position of the closure relative to the container and for a processor device to determine from this rotational position whether the closure is properly arranged on the container.
- limit values for the rotary position can be defined. If the rotational position determined is within these limit values, the container is considered to be properly closed, if the rotational position is outside these limit values or at least above one of these limit values, the container is considered defective.
- the recognition can contain an ambiguity check. Should a closure have a thread which, for example, encompasses approximately or more than 180°, an ambiguity could arise, namely if the closure is screwed on too little by one or more complete revolution(s). In this case, the rotational position of the closure relative to the container could be within the allowed angular tolerance, but still not seal as required.
- This case can preferably be recognized in a simple manner by a further image processing evaluation of the recorded camera image. The evaluation is carried out analogously and in combination with the cap seat check described above, for example as a two-stage process.
- the device has an ejection device which ejects containers identified as defective and in particular containers identified as incorrectly closed.
- the inspection or control is preferably carried out after the containers have been filled and sealed, where in the neck area of the containers water droplets often adhere both to the inner wall and to the outer wall. These are better recognizable in transmitted light. Therefore, preferably the features on the container are formed as distinct and multiple, i.e. duplicate or multiple, vertical structures. As described in more detail below, these can be arranged protruding (embossing) or recessed (debossing) both on the outer wall and advantageously on the inner wall.
- the cross section of these structures preferably has clear edges for reasons of better visibility and can be, for example, rectangular, trapezoidal, particularly preferably triangular or sawtooth-shaped, since closely spaced edges and in particular sloping edges enable a particularly strong contrast in a camera image.
- the horizontal width of the structures is in the range from 0.25 to 2.5 mm, preferably in the range from 0.5 to 1.5 mm and particularly preferably in the range from 0.75 to 1.25 mm.
- the vertical extent of the markings is preferably greater than 1.0 mm, preferably greater than 2.0 mm, preferably greater than 2.5 mm and particularly preferably greater than 3.0 mm. This size has proven particularly advantageous as it is larger than the diameter of typical droplets.
- a length extension of these markings is preferably less than 3 cm, preferably less than 2 cm, preferably less than 1 cm and preferably less than 8 mm.
- the evaluation device is preferably suitable and intended for distinguishing between such structures or markings and water droplets.
- a search algorithm can be provided, such as shape matching, which is particularly preferably optimized to identify the corresponding structure, especially in any rotational position.
- the position of the structures could be detected and the angular position thus calculated using a deep neural network, for example CNN.
- a deep neural network for example CNN.
- This can be trained, for example, with a large number of annotated camera images (i.e. enriched with angular position information) so that it can determine the position angle from the position and appearance of the marking in the images at runtime.
- the marking is usually located at an essentially fixed, defined height position, ie in the image the area in which the markings will be located is relatively strongly delimited, which also makes it easier to identify the respective structure.
- the position of the mark is determined by the bottle manufacture:
- the marks should be arranged in an area that does not change when the bottle is blown. It is possible for the determination of the structure to take into account both the distance between the two lines recorded in the image and its position within the image, if it is assumed that the imaging device is always essentially aligned with the longitudinal direction of the container.
- the features on the container and/or the features on the container closure can be recognized with the same image acquisition unit.
- the image capturing device or the image recording device therefore preferably records both an image of the closure and at the same time an image of said region of the container.
- this image capturing unit can have a camera and lighting.
- the device has a further lighting device, which is in particular on that side of the container is arranged, on which the image recording device is also arranged.
- incident light illumination is (additionally) proposed, which in particular also serves to illuminate the container closure. This is particularly useful when the container closure is made of a non-transparent material, as is usually the case. If only one image recording device is used in this advantageous embodiment, this is preferably arranged at an angle of observation obliquely from above, so that both the container closure and the mouth region lying below the container closure can be detected.
- a further image recording device which also records the rotational position of the closure using methods known from the prior art (CETIE).
- CETIE the prior art
- these two image recording devices it is possible for these two image recording devices to be synchronized with one another.
- symmetrically multi-part, for example three-part threads are used on the container mouths. If the same number of alignment features, e.g. three, are attached to the container and the closure in a fixed angular relationship to the thread, the entire finish circumference does not have to be checked, but only the corresponding fraction, e.g. one third.
- the angular range to be recorded can preferably be recorded with a single image recording device and special optics.
- the image recording device therefore preferably has an optical device which allows an at least partial all-round view in order to capture this in one piece.
- the angular range it would also be possible for the angular range to be composed of several individual views, with the partial views advantageously overlapping in order in this way to reliably capture the features in each angular position as a whole.
- the multiple views can preferably be imaged via one or more image recording devices or cameras and/or via mirror systems, so that multiple individual views can also be recorded with an image recording device, or a separate camera can also be used for each individual view.
- an image evaluation device which enables rectification of recorded images. This is advantageous because due to the perspective or oblique imaging and also the typical circular circumference of the containers and the closure, there is a highly non-linear relationship between the position of the feature in the camera image and the angular position relative to the container.
- a viewing direction of the image recording device preferably encloses an angle of more than 3°, preferably more than 5°, preferably more than 7° and preferably more than 10° and preferably more than 12° with a direction perpendicular to the longitudinal direction of the container ° a.
- a slightly oblique observation of the container is advantageous in order in this way to be able to eliminate reflections or optical artefacts originating from the rear wall of the container circumference.
- the lighting device has a width (in particular in the circumferential direction of the containers to be inspected) that is selected in such a way that it appears only slightly wider than the closure in a recorded image.
- the width can be less than a cross section of the illuminated container.
- the containers usually have a base body have a cross section that is larger than the cross section in the neck or mouth area.
- the lamp width is advantageously narrow and slightly wider than the shutter in the picture.
- the vertical marks darken well and the position can be determined on the complete shutter. If the lighting device, such as a lamp, is narrower at the sides, the contrast of the vertical cam flanks or the markings becomes better.
- a tall, narrow lamp is used, that is, a lamp that is long in the longitudinal direction of the container and comparatively short in the direction perpendicular thereto.
- the narrow design favors the visibility of the markings on the containers.
- the comparatively large length in the longitudinal direction or the large height is favorable for suppressing horizontal thickening.
- the present invention is also directed to an inspection device for inspecting filled containers with container closures arranged thereon.
- This inspection device has a transport device which transports the containers along a predetermined transport path. Furthermore, the inspection device has an illumination device, which illuminates the containers to be inspected, and an image recording device, which is suitable and intended for recording spatially resolved images of the containers.
- the image recording device is also aligned at least on areas of the containers which are arranged in a longitudinal direction of the containers below the container closures arranged on the containers, and a viewing direction of the image recording device encloses an angle of more than 20° with the longitudinal direction of the containers, such that that at least one marking applied to the containers can be detected by the image recording device.
- the device has an evaluation device which determines a relative rotational position of this container with respect to the container closure arranged on the container from an image of the container provided with the marking or from an image taken of this container.
- this determines a relative position of the container closure in relation to the container, in order in this way to conclude that a closing process has taken place.
- the present invention is also directed to an inspection arrangement for inspecting filled containers with container closures arranged thereon, which has an inspection device of the type described above, and a container to be inspected, wherein the container closure arranged on the container has at least one first optically perceptible marking, and the container has at least one second optically perceptible marking below the container mouth.
- both markings can preferably be detected with the same image recording device.
- Said second marking is preferably arranged in a neck area of the container.
- the present invention is also directed to a method for inspecting filled containers with container closures screwed onto them, with a transport device transporting the containers along a predetermined transport path and an inspection device using an illumination device to illuminate the containers to be inspected and an image recording device to record at least one spatially resolved image of the containers .
- the image recording device is also aligned at least with areas of the container which are arranged in a longitudinal direction of the container below the container closures arranged on the containers and a viewing direction of the image recording device closes an angle of more than 20° with the longitudinal direction of the containers in such a way that at least one marking attached to the container is detected by the image recording device.
- an evaluation device uses at least one recorded image of the container provided with the marking to determine a relative rotational position of this container in relation to the container closure arranged on the container.
- the evaluation device or another unit emits at least one signal which is characteristic of whether the container is a correctly closed container or an incorrectly closed container acts.
- containers which are identified as faulty are ejected from a production flow.
- a discharge unit can be arranged downstream of the inspection device, which enables individual containers to be discharged from the production flow.
- the relative rotational position of this container in relation to the container closure arranged on the container is determined by means of a neural network, in particular an appropriately trained neural network.
- FIG. 1 shows a schematic representation of a device according to the invention
- FIG. 2 shows a schematic representation of an inspection device according to the invention
- Fig. 3 is a representation of an inspection device according to the invention in a
- FIG. 1 shows a schematic representation of a device according to the invention.
- a filling device 4 which fills containers, for example PET or glass containers, with a liquid. These filled containers are then closed by means of a closing device 5, this closing device 5 applying closures to the containers and, in particular, screwing them on.
- the reference number 2 denotes, roughly diagrammatically, a transport device which transports the containers 10 between the individual treatment stations.
- Reference number 6 designates an inspection device which inspects the containers and in particular their closure area in order to determine a rotational position between the closures and the containers.
- the inspection device 6 has an evaluation device 60 which evaluates recorded camera images.
- the reference symbol T designates the transport path of the plastic containers.
- the reference number 8 designates a separation device which is suitable and intended for separating containers from the transport path T, for example diverting them onto a reject path T1. This separating device is preferably also controlled by the control and evaluation device 60 and, in particular, rejects those containers which have been identified as incorrectly sealed.
- FIG. 2 shows an illustration to illustrate the invention.
- an illumination device 62 is provided which illuminates the container closures.
- the reference number 10 denotes the container and the reference number 10a denotes a closure attached to the container.
- the reference character L designates a longitudinal direction of the container. It can be seen that a marking 22 is attached to both the closure 10a and a marking 24 to the container 10, more precisely in the mouth area of the container.
- an image recording device 64 the relative position between the marking 22 and the marking 24 (more precisely the relative rotational positions with respect to the longitudinal direction L) are determined. It is possible that only one camera is sufficient to record these images.
- FIG. 1 shows an illustration to illustrate the invention.
- the image recording device looks at the container in an exactly horizontal direction or at an angle ⁇ of 90° with respect to the longitudinal direction of the container.
- the image recording device views the container obliquely from above, preferably at an angle to the longitudinal direction of the container of between 70° and 80°, preferably between 72° and 78° and particularly preferably around 75°.
- Figure 3 shows an illustration in which two image recording devices 64 and two lighting devices 62 are provided, which are however arranged at an angle to one another with respect to the longitudinal direction of the container in order to be independent of the respective position of the markings on the closure 10a or on the container 10 to be able to determine the respective markings.
- an additional lighting device to be provided which also illuminates the container closure, with this lighting device preferably being arranged on the side of the image recording device 64 (not shown) in order to illuminate the container closure in incident light.
- FIG. 4 shows a detailed representation of the container 10 with the closure 10a arranged on it.
- the reference number 10b denotes a carrying ring of the container and the reference number 10c denotes the neck or mouth area of the container. It can be seen that here the marking 24 is arranged in the form of two vertical lines directly on the neck area below the carrying ring.
- containers often have thickenings below this support ring 10b, because this is where the transition area between the cooled mouth and the heated preformed body is. These thickenings partially direct the horizontal line of sight into a dark cover, making it difficult to identify the marking 24 . As mentioned above, this can be remedied by viewing at an angle from above. Despite the light refractions at the thickening, it is easier to look under the cover.
- a further improvement can be achieved if the lighting device (shown only in broken lines here) is laterally narrower, because then the contrast of the vertical cams 24 is improved.
- Optimal is a high narrow lamp, with the narrow design serves for the visibility of the cams, and the height of the lamp for the suppression of the horizontal thickening.
- flanks with angles of 30° to 60°, with the counter-flank preferably directly adjoining (triangular prism).
