    The present invention relates to an inspection device with which the containers can be checked for deterioration. The invention also relates to a production equipment with which containers of this type are processed and which contains an inspection device according to the invention. Finally, the present invention comprises an inspection process with which these containers can be checked.
    Containers, such as cans and bottles, which are used to store foodstuffs, chemicals, medicines and other products, must be analyzed for damaged points before being filled and placed on the market to ensure that, on the one hand, supply process goes smoothly and, on the other hand, the contents of the containers do not deteriorate or have their quality impaired, as well as a leakage of liquids is safely prevented.
    Often, containers, such as cans, are shaped by known modeling processes in the opening area to produce a rim on the neck of the container. This flange is particularly suitable for attaching a sealing membrane or other sealing element to the container, for example, a valve. Therefore, it is necessary that the rim does not show damaged points. In order to establish, in advance, if the modeling process caused damage to the can or also if the bottle necks are damaged, which also have an opening thickening in the rim type, on which, for example, crown caps can be attached. bottles or cans are usually analyzed immediately after production. In this case, the known production processes use imaging technologies, with which it is possible to register the sensitive bottleneck of bottles or cans with the imaging process. Notably, bottles and cans, when received from the previous processing equipment, are removed, in this case, from the equipment and transferred to a camera in the lying position. The bottles or cans are fixed in a cup-shaped housing only by force of gravity, being positioned with less precision only at the support point and being received on a mobile conveyor, depending on the diameter in relation to the position of its longitudinal axis , which represents a disadvantage for taking high definition images. Minor damage, for example, scratches in the paint or very small depressions at the edge of the rim, which require a high definition image, may be sufficient for the liquids to leak out of the container without a precise seal or to penetrate, for example, oxygen into the container and the content is disadvantaged by oxidation.
    The known imaging processes aim to reproduce the neck of the bottle in the frontal registers; the resulting lower cuts at the edges of the flanges and at the edges of the bottles mean that the areas located below the opening surface of the bottles are not captured by the image or are insufficiently captured and thus cannot be controlled.
    Considering the most modern technology, the need arises to provide an improved inspection device to check the containers, which allows to offer an improved image quality to assess the damaged points in the containers. This objective is solved with the inspection device with the characteristics of claim 1.
    There is also the need to create an improved production equipment, with which the containers can be produced respectively processed, as well as allowing to obtain inline images with improved registration quality of the container, and it is desirable to register not only a perspective of above the surface of the container neck, but also to obtain the widest possible image. This objective is solved with the production equipment with the characteristics of claim 7. There is also the objective of creating an improved inspection process, which allows to reproduce, in a precise and reliable way, the quality of the containers directly in the production. This objective is solved with the inspection process with the characteristics of claim 10.
    The corresponding improvements of the device and the process are detailed in the respective sub-claims.
    A configuration of an inspection device according to the invention serves to analyze the containers fixedly arranged on a processing machine.
    In this case, "containers" means, below, a can that can be filled with a spray or other liquid and which is modeled, in this case, on a processing machine, for example, a retraction machine. These cans are produced predominantly from metal. However, "container" can also be understood as a bottle, even glass or plastic bottles, as well as other containers, for example, vases and the like.
    "Processing" is understood as modeling in fact, for example, the affixing of a surface coating, the polishing of the surface or, in the case of glass processing, the sharpening or other type of finishing of a blank or a object to be modeled, which should be transformed into a container.
    The inspection device of the present invention serves to assess the damage of the surface of containers of this kind by taking images; damage can be considered, in this case, scratches in a painting layer, as well as depressions, particles of material detached, cracks or cracks and other damages in the internal and external part of the container.
    The inspection device has a tripod to which a camera is attached, which is associated with an optical construction element, for example, one or more lenses, or with another suitable optical construction element. Cameras of this type are known to those skilled in the art. The camera has a conventional image processing unit. The image processing unit may be associated, in a manner known to those skilled in the art, with other data or image processing units, in order to enlarge and store the recorded images or to generate adjustments with the data processing units, and it may also include a coupling with a database, in which comparative images of the ideal containers are deposited without damage, making it possible to immediately remove the damaged container from the production equipment or from a coupled transport equipment when damage is recorded and subsequent image comparison.
    The camera and the integrated lighting device are attached by a support associated with the tripod. The camera defines, using its optical construction element, an image receiving axis, which indicates the direction of the container to be observed, which is explicitly so-called "inspection position": In this position, the central longitudinal axis of the container to be observed aligns with the camera's receiving axis.
    The inspection device also has a component that moves in relation to the tripod and is also mobile. This component comprises a retaining tube, within which a second optical construction element is arranged. The holding tube is arranged in a coaxial direction with respect to the receiving axis in an area between the camera and the container and moves in an axial-parallel direction towards the container. The opening cross-section of the movable holding tube is greater than the maximum outer circumference of a cut of the container to be observed. When the container to be observed is in an inspection location, the inspection device is transferred to an image taking position, with the retaining tube being moved over the container, making it necessary to cut the container at least to be observed by the retaining tube. In this case, the radiation process is carried out by the lighting device until the container to be observed is cut and from that location by the second optical construction element to the first optical construction element of the camera. The retention device may be, in a configuration of the invention, a tube coated with a metal material, metal alloy, plastic or fiber composite, the central longitudinal axis of the coated tube being aligned with the receiving axis of the camera and thus also to the central longitudinal axis of the container in the inspection position. The outer circumference of the coated tube is smaller than the opening cross-section of the retention tube, allowing the retention tube, if removed from the imaging position, to fully or partially cover the coated tube. Then, the next container to be observed will be able to assume the inspection position without hindrance.
    While the first optical construction element coupled to the camera can usually be a lens or a lens arrangement, the second optical construction element can be a mirror, in particular, a concave mirror or a parabolic mirror with a central access opening. This mirror arranged in the retaining tube advantageously allows the container to be captured in an integral and circumferential way, including its side walls. The mirror has an access opening and is moved over the container, in the image taking, in the desired proportion, by the mobile retention device. In this case, its curvature is arranged so that the camera lens can still capture the lower cuts and walls through the mirror.
    Alternatively, an endoscopic lens may be arranged on the retaining tube as another element of optical construction, maintained by a support on the retaining tube, parallel and centralized in relation to the central longitudinal axis of the retaining tube. One end of the endoscopic lens points towards the camera. This end is not associated with the camera, but a reception area of the camera is adjusted, by the first construction element, respectively by the lens, to the front area at the end of the endoscopic lens, with an image transfer from the endoscopy lens to the camera. . The second end of the endoscopic lens is aligned towards the container that is in the inspection position, whose opening of the container is facing the endoscopic lens in order to allow an exchange of the second end to the inner area of the container.
    Advantageously, the present inspection device is suitable to be integrated into the production process already inline and to produce images of the container at the end of the line or processing path after the last processing phase, while the container is still fixedly on the processing machine. In this way, it is possible to obtain accurate and high definition images, which involve the least damage to the containers. Therefore, a production equipment for the manufacture of containers, which comprises at least one processing machine to treat the containers, features a mobile transport equipment, which moves the containers, meanwhile, fixedly fixed on the transport equipment. In this case, the containers fixedly attached to the transport equipment pass through several processing stations on the processing machine, for example, modeling devices, without the containers having to be transformed.
    The production equipment according to the invention also comprises an inspection device with which the quality of the containers can be analyzed, as described above, after processing. In this way, "quality of the containers" means that there is no damage to the surface, and the damage can range from cracks to scratches to material detachments and depressions.
    In the production equipment according to the invention, the inspection device is integrated via a tripod allowing the camera, with the respective image processing device and the optical construction element associated with the camera, to produce wide images, in a way appropriate, not only from the top perspective of the neck of the containers, but also from the lower cuts located behind the neck, in the areas of the inner and outer walls.
    If only images of the neck of cans or bottles, for example, of their opening surfaces, should be reproduced, a simple inspection device may be used, which includes a holding device, preferably a coated tube, in (a) which the camera is attached to a lighting device. The radiation process of the camera and the radiation process of the lighting device take place correspondingly to an image-taking opening of the metal tube so that the beam of light, which manifests itself, can skillfully illuminate the object to be analyzed and the camera can produce images.
    According to the invention, the inspection device is integrated with the inline production equipment, and can be installed at the outlet of the processing machine. This has the advantage that the processed containers are still fixedly attached to the transport equipment and, therefore, do not move when the images are captured, making it possible to obtain excellent image quality. The inspection device, comprising the holding device attached to the tripod, to which the camera is attached with the first optical construction element and the lighting device, is installed on the processing machine in relation to a container to be observed, which is in an inspection position, so that the camera with the first optical construction element points in the direction of the container to be observed along a receiving axis, and the receiving axis is aligned with a central longitudinal axis of the container in the inspection position.
    The inspection device can advantageously be coupled to the processing machine by means of control equipment, in order to coordinate control of the inspection device in relation to the transport equipment so that the image taking to analyze the quality of the containers is carried out during a retention phase of the transport equipment with the container to be observed in the inspection position. This retention phase is provided for a period necessary for the processing machine to process a container. This retention phase allows excellent image quality, together with the fixed arrangement of the containers in the transport equipment and the camera installed in a fixed position.
    An inspection process to be carried out on production equipment of this type to analyze the quality of the containers after their processing therefore involves fixing the containers on the mobile transport equipment of the processing machine, so that the containers can be processed in several processing stations of the processing machine. Advantageously, an analysis of one of the containers arranged in the inspection position is also carried out on the processing machine, in which the central longitudinal axis of the container aligns with the receiving axis of the camera. In order to take an image of the respective container to be analyzed, the inspection device is controlled by the control equipment, in a coordinated manner in relation to the transport equipment, making it possible for the inspection device to analyze the container that is in position of inspection while the transport equipment is interrupted. A retention phase of this kind is planned during the processing period of the containers at the processing stations. The longest processing phase will determine the duration of the retention phase, which is at least shorter.
    In order to produce wide records, as described, and also to produce images of the inner part of the container or cuts of the side walls and lower cuts, an inspection device can be used, which presents moving components in addition to the static ones.
    According to this process, the mobile building components of the inspection device and consequently the retaining tube with the second optical building element will run in an axial-parallel direction in relation to the receiving axis towards the container to be observed in the image-taking arrangement, allowing the cut to be observed from the container to be located in the holding tube; however, the holding tube can also be guided through the entire container. The radiation process will be carried out correspondingly by the lighting device until the container to be observed is cut and from that location by the second optical construction element to the first optical construction element of the camera.
    It is especially advantageous when the moving component is a retaining tube, in which a mirror is installed, for example, a parabolic mirror or a concave mirror, which has a central access opening and can be guided by the objective, from which it must be picture taken. With the movement of the mirror along the container to be analyzed, the lower cuts can be captured without problems, making it possible for the container to be captured by the camera not only from the top perspective, but also by the mirror lens in the retention tube indirectly in a wide side perspective. To record a wide internal perspective of the container, a retention tube with an endoscopic lens can be used, which, while the retention tube is capturing the container to be observed, can be taken to the internal area of the can or bottle. to be analyzed, and it is possible to analyze almost the entire geometric internal format.
    This and other advantages will be represented in the description below, referring to the attached figures.

    The invention relates to an inspection device, with which a container, for example, a can, can be analyzed, at the end of production, as to its shape and as to eventual production defects. This analysis is carried out, according to the invention, inline in production in progress, being analyzed each container produced, each can respectively.
    In the present invention, a container or can is understood to be a container with a linear expansion, which may have, as shown in Figures 1 and 6, a contour with collars, curvatures and notches. The upper opening of the container 20 is surrounded by a margin of the flange 21 there.
    Below the margin of the flange 21, a constriction is associated, which does not allow that area of the neck of the container 22 to be registered in an observation from above, as indicated by the arrow a, since a lower cut is formed. Also the bulging, see arrow b, prevents a view from above.
    In order to carry out a final non-contact control on a processing machine, such as a retraction machine 10 in Figure 2, which is supplied by a feed conveyor equipment 12 with cans to be processed, and which is coupled to a conveyor belt 13 , which transports the containers in cartridges, with which the external and internal surfaces of the container can be analyzed, the processing machine 10, in which a series of containers is fixedly attached to the transport equipment 11 and which is moved by this equipment , an inspection device according to the invention is installed at the point of the processing machine 10 which is indicated by the container to be observed 20, in the inspection position, at the outlet of the processing machine. The inspection device 1 according to the invention can be seen in Figures 3, 4, 5 and 7. The inspection device 1 has, in this case, a tripod 9, to which a coated tube 4 is attached as a holding device. for camera 2 and lighting 5 units 5. Coated tube 4 may be a metal tube, for example, a steel tube, however, it may also consist of a plastic or fiber composite material. In the coated tube 4, there is the camera 2 with a corresponding optical construction element 3, as well as the 10 lighting units 5 for reception, being a reception area of the camera 2, respectively its radiation process, extended due to an opening 4 'of the coated tube 4 modified by the tripod 9. As shown in Figure 3, the coated tube 4 is installed together with the camera 2 in such a way that its longitudinal axis and its imaging axis form a common axis AA with the longitudinal axis of the container 20 to be tested, which is transported by the transport equipment 11 of the processing machine. The containers are permanently attached to the transport equipment 11, allowing the container 20, which is in the inspection position corresponding to the receiving axis A-A, to be positioned exactly in the registration area of the camera 2.
    The movement of the containers on the processing machine by the transport equipment is not continuous in this case and is carried out in batch due to the processing period of a container, successively making each container retain its longitudinal axis briefly on the receiving axis AA of the camera 2 during the period foreseen by the processing, in order to be analyzed in that location. The inspection device 1 is controlled in such a way that the analysis sequences of the inspection device 1 run in coordination with the holding cycle of the transport equipment 11. Therefore, both can be coupled to a control device (not shown). With the camera 2 installed only in the coated tube 4, it is possible to register only one perspective from above the container 20, and the shaded areas behind the curvatures, for example, the edge of the edge 21, cannot be registered.
    In order to also be able to register the shaded areas with the camera 2, the inspection device 1 according to the invention has a carrier element 7 'that moves parallel to the longitudinal axis of the coated tube 4, which, as shown in Figure 3 , it can pass over a bar 8, arranged parallel to the coated tube 4, fixed on the tripod 9. The carrier element 7 'has, in the area where the retaining tube 7 is attached, an access opening for the coated tube 4 , which is advantageously equipped in order to avoid practically any infiltration of foreign light into the internal area of the retention tube 7, the internal volume of the retention tube 7 being predominantly illuminated by the lighting units 5.
    A circumferentially moving mirror element with a 6 '' access opening is installed in the retaining tube 7, the diameter of which is developed to allow the retaining tube 7 with the mirror element 6 to be processed by the largest cut section of the container 20 to be analyzed. The mirror element 6 may be designed differently from that represented, for example, as a parabolic mirror element, with the access opening 6 '' being arranged in the concentric area, centered in relation to the A-A axis. The retaining tube with the mirror element disposed therein, as well as the coated tube and the access opening of the carrier element, must not necessarily have circumferential cross-sections. Depending on the shape of the cross section of the containers to be observed, the retaining tubes with the mirror elements may be selected with corresponding shapes of cross section, and, in an equivalent way, the coated tube and the respective access opening will also be adjusted to the carrier element.
    In Figure 1, the container 20 shown with an inspection device 1 corresponding to Figure 3 is shown, together with the radiation processes allowed by the moving mirror element 6. The process of the retaining tube 7, attached to the carrier element 7 ', for the mirror lens 6 is indicated by the arrows c and c': the arrow c symbolizes the movement towards the layout of the image taking and the arrow c 'illustrates the removal to allow transport of the next container to be observed to the inspection position. The radiation processes develop from the lighting units 5 to the container 20 (not shown) and from that location, from the bottom cut observed 22, passing through the mirror 6, to the lens 3 of the camera 2. In this way, they can be both paint defects and defects such as holes, ie cracks, that penetrate the material from the outside to the inside, or the so-called pinholes, among which it is believed that there is a material defect smaller than an orifice or crack, however, that could imply, in continuous processing, for example, in the filling of the container, material damage and rupture of the container.
    In Figure 4, an alternative inspection device 1 is shown, in which, instead of a camera, two cameras are installed, with a lighting unit 5 in the coated tube 4. The improved registration area in relation to the mirror element 6 The special feature of the two cameras 2 allows an even better assessment of the opaque areas of the container 20, for example, in the case of an asymmetric container, in which the reflective radiation processes by the container cannot be focused by a single camera. The radiation process represented with a dashed line, starting from the lighting unit 5 to the opening 4 'of the coated tube 4, indicates that, in this case, an optical transfer element, for example, an optical fiber, can also be used, allowing the illumination area is located outside the coated tube 4 and, in this way, the container 20 will be illuminated and not the inner area of the coated tube. The same principle applies to the radiation of light reflected by the mirror lens 6, the radiation process is focused on the exit of the coated tube 4 'and continues to be transferred to cameras 2 on the coated tube 4. For this purpose, it is imagined that other optical building elements can be used. The container 20 shown in Figure 2 presents, in addition to the constriction 22 below the margin of the edge 21 in the cross section, a wave profile with four recesses 24, which can also be analyzed with the inspection device according to the invention, as that the special mirror element 6 is moved to the lowest recess and, thus, allowing a perspective on the lateral areas of the container, which could not be captured otherwise, with the camera facing upwards.
    Figure 7 shows another configuration of the inspection device 1 according to the invention, which can be used as an alternative or in addition to the inspection device represented with the mirror element 6 to register the outer surface of the container 20. Using another element of inspection. special optical construction 6 ', in this case, of an endoscopic lens 6', the inner surface of the container 20 can also be observed. As it is not necessary, in an embarrassed way, in the analysis of the external surface, that an opening of the container point in the direction of the camera, although this depends on the formation of the container - for example, in the case of a constriction subsequent to the opening of the container, ie a bottle neck - it often happens that the container 20 is arranged in the inspection position with its opening towards the inspection device, respectively of the camera, to perform the analysis of the internal area. In the retaining tube 7, the endoscopic lens 6 'is now retained by means of a suitable and centralized retaining element 7' ', which positions the endoscopy lens 6', which may be an optical fiber, corresponding to the AA receiving axis, respectively, from the central axis of the container 20. In this case, the endoscopy lens 6 'is now moved by the bar 8 over the carrier element 7' associated with the retaining tube 7 in an axial-parallel direction to the coated tube 4 in relation to the tripod 9, allowing the endoscopy lens 6 'to be inserted into the container 20 through its opening, as the retaining tube 7 is moved over the container 20. The uninserted end of the endoscopy lens 6' is with its front area of the camera 2 facing for their respective optical construction group, the gap between their frontal area and camera 2 being continuously changed during the analysis process due to the 6 'endoscopy lens movement. The camera, respectively the optical construction group 3, is developed in such a way that the front area of the endoscopy lens 6 'is registered during the analysis, and a reception area of the camera 2 can be adjusted to a mobile front area, the length of which allows the camera-facing end 2 to be kept static as the opposite end is driven into the inner area of the container. In this case, it is sufficient to focus the camera reception area only once on the front area of the endoscopic lens.
    The integration of an inspection device of this type with the production equipment 10 (see Figure 2) with the transport equipment 11 allows a fast and high precision analysis of both the internal and external area of a container, for example, of a can, making possible that defective containers and contaminations are removed from continuous processing. To automate these developments, the camera can also be coupled to an image processing unit, in which a full image of a properly processed container is stored, so that the processing unit can verify, by comparing the captured image with the stored image, if the test container is intact or has a defect or contamination. The increased precision of the analysis was obtained by integrating the inspection of the production equipment with the processing machine, and not in the way it has been performed so far at the end of the belt, where the containers are no longer fixed in order to allow a positioning of high precision.
