- the present invention is directed to an apparatus and method for using machine vision systems to identify defect information related to a formed metal container and then associating that defect information to the container's body maker, trimmer or other machinery in the manufacturing path through the factory.
- the disclosed invention consists of modifying the die sets used to form the bottom portion of a two-piece food or beverage container to include a unique surface relief pattern or code.
- the coded marks can be either concave or convex in the bottom of the container and can be obtained by so modifying the doming punch accordingly.
- the code design or pattern is preferably chosen so as to facilitate unambiguous detection and decoding operations by a machine vision system.
- the code provides good visual contrast to the machine vision system, is decodable by the system using a minimum of processing time, does not significantly interfere with the ability of the machine vision system to detect defects that are present, does not in any way interfere with the form, fit, or function of the container, is readable by humans in at least some forms and is inexpensive to retrofit into existing doming punches or dies.
- containers formed by multiple, parallel-operating body makers or presses can be serialized into a single-file, high-speed conveyance line as is typical at many points within plants.
- machine vision systems are typically used to perform high-speed defect attribute inspection on the serial can stream.
- Figure 1 shows a candidate machine-readable code 10 according to the present invention.
- This example code consists of a fiducial element 11 that is used to locate and orient on a 4-bit binary code composed of a rectangular pattern of up to four dots 12.
- a top view of a doming punch 9 having the example code 10 formed thereon.
- the code 10, or other codes, are formed on the doming punch in manners that will be apparent to those skilled in the art. It is to be understood that a doming punch is shown as an example. Other stamping and impressing hardware may be implemented.
- the doming punch 9 has the code 10 formed in an area 8 (shown by the dashed circle for illustration purposes) that corresponds preferably to an axially centered region 24 of the dome of the container (which is described in Figure 2).
- the code is preferably totally contained within the axially centered region in the dome.
- this region is circumscribed by a circle having a diameter of approximately 12mm.
- the code, once stamped or impressed into the container, is preferably readable from the interior of the container.
- the identifying code can be quickly deduced using modified algorithms that were originally designed primarily for defect attribute detection. Algorithms as described herein are well known in the art.
- the system is operative to obtain an image of the container under inspection and, when determining the code, uses the fiducial to properly orient the image so that a proper comparison of the imaged code can be made to stored information, or codes. With proper orientation and comparison, a manufacturing path or the source of origin of an imaged container can be determined. It is the intention of this invention that an identifying code as indicated in Figure 1 be stamped into the container as a surface relief attribute on the container bottom using press-specific dies. It should be appreciated that other known techniques for forming a surface relief code in a metal container surface may be used.
- a manufacturing system for producing metal containers, stamping or impressing container codes within those containers, inspecting the containers to determine codes and defects, and associating those containers to paths of manufacturing or sources of origin based on the codes to generate quality status information is illustrated. More particularly, a system 1000 is shown wherein objects or containers are conveyed along paths shown at 120. As illustrated, these containers (or cups), in some form, are processed through body maker machines 500 and body trimmer machines 600 on a plurality of parallel paths, as is known. The containers are then merged onto a single path and processed through other processing machines 300 and, ultimately, provided to an inspection and/or imaging system 400 having an inspection zone 130.
- the containers are stamped with a container code, such as those as shown in Figure 1, in the body maker machine 500.
- the code is stamped in a location in the container such the structural integrity and inspectability of the container is maintained.
- the dies or doming punches (such as a doming punch 9) are modified, as shown in Figure 1, by any known means, so that the appropriate code is pressed or stamped into the containers. This allows for the determination of the source of origin or the manufacturing path of the particular container to be identifiable at the inspection zone 130.
- the path of manufacturing and corresponding system components illustrated in Figure 7 are merely illustrative and could otherwise take a variety of forms.
- the number of operating body makers may vary substantially (e.g., from several to sixteen), depending on plant configuration and product needs.
- the placement of a code, or container code, according to the present invention would preferably be on the can bottom, in a small central base region 24 that is co-linear with the can axis. Placed in this location, the code attribute would interfere in a minimal fashion with the ability of the machine vision system to inspect the container for defect attributes.
- the central base region 24 is preferably of a size so that illuminating the code does not create ghost images on the sidewall from disturbances to reflections of the illumination source that is illuminating through the opening of the container or can.
- the code is totally contained within an axially centered region in the dome of the bottom of the container which is circumscribed by a circle having a diameter of approximately 12mm.
- Figure 2 provides a schematic outline of a two-piece beverage can body 20 being imaged by an imaging lens/camera combination 21.
- a region of zero base reflection off the container sidewall 23 is found in the central base region 24.
- container attributes both functional such as an identifying code, as well as defect attributes
- the ability of the machine vision system to inspect the container 20 in both the base region 22 (wherein the code was placed) as well as the sidewall region 23 would be adversely affected and would complicate or compromise the inspection process.
- Additional incentives for locating an identifying code 10 in the central base region 24 of the container 20 is drawn from the fact that the central base region 24 is the least worked portion of the container in regards to metal deformation. As such, container defects rarely occur in this region of the container, thus reducing the need to perform defect attribute inspection in this region. Placement of a identifying code does not completely eliminate the ability to inspect the container in the region wherein the code is placed.
- Figure 3 provides a schematic outline of a preferred embodiment of the disclosed invention.
- a container 20 (having a container code 10 appropriately placed thereon using a variety of known techniques, including those mentioned herein, to indicate its original body maker or press of origin) undergoing inspection is transported into an inspection zone 130 via some means of object conveyance 120.
- object conveyance 120 There are various types of part or object conveyor systems that have been constructed and are well known in the art.
- a spectrally and spatially configurable illumination field 140 is generated by the solid-state illuminator 50 and directed onto the container 20.
- the solid-state illuminator 50 is constructed out of an array of individual LED's 60.
- the illuminator 50 implemented in the embodiments described (e.g. Figures 3, 4 and 5) includes in at least some forms solid state illumination arrays and is positioned to illuminate the interior of the container. Preferably, reflected illumination is used to implement the system. Also included within the preferred embodiment of the solid-state illuminator is a diffuser 150.
- the diffuser 150 homogenizes the emitted illumination fields 140 in regards to their spatial uniformity. In many automated measurement or inspection applications, spatially uniform illumination fields 140 are required for optimum system operation.
- the LED's are deployed in a three-dimensional shape approximating a hemisphere. This shape of illuminator is well known in the art having the properties of generating highly uniform isotropic illumination. This type of illumination is preferred for many classes of inspection or measurement applications.
- other LED array configurations such as flat panel arrays or annular ring lights find useful application in other cases.
- the spirit of the invention includes the implementation of the solid-state illuminator 50 using these alternate physical configurations.
- reflected light 141 is directed first in the direction of the solid-state illuminator 50 and on through to a beam splitter 30.
- the beam splitter 30 is used to selectively direct the reflected light into 2 different images or channels.
- One image or channel is the defect attribute image or channel 142 while the other image or channel is the container code image or channel 143.
- Beam splitters 30 as indicated herein are well known in the art, being deployed in a variety of state-of-the-art machine vision systems for a variety of reasons. Such beam splitters 30 can be designed and manufactured with a variety of reflection/transmission specifications. It is typical in many machine vision systems to use a 50/50 beam splitter design.
- the ideal beam splitter construction would differ from a 50/50 device.
- the reflected illumination fields associated with metal food or beverage container are very non-uniform as a function of container radius.
- There is an order of magnitude difference in the reflected intensity as one moves about along the inside can surface. More specifically, the reflections coming from the container bottom, located normal to the optical axis of the system are very strong. In contrast, the amount of light glancing off of the container sidewalls in the direction of the optical axis of the imaging system is quite low.
- the imaging lens 70 needs to operate within the visible spectrum and be able to form an image of an object or a scene at its back focal plane.
- both cameras 40 (the one associated with the defect attribute channel 142 and the one associated with the container code channel 143) send image data to an image processor 80.
- the two image signals produced by the cameras 40 can be directed to a video multiplexing module 160 that acts to electronically combine the two independent video streams into a single compound video channel.
- Video multiplexers 160 as described herein are well known in the art.
- the image processor 80 receives a signal from a part presence mechanism 90 that indicates to it that a container 20 is about to pass through the inspection zone 130.
- Part presence mechanisms 90 such as photo-eyes are well known in the art and are deployed in many applications within many different industries.
- the image processor 80 issues control signals to both cameras 40 and the solid-state illuminator 50.
- a signal is issued by the imaging processor 80 to a status enunciator 100.
- the status enunciator 100 could be implemented as a rejector that physically removes parts determined to be below, or alternately above, a predetermined quality standard. Alternately, the status enunciator 100 could be implemented as a type of audio or visual warning signal indicative of part quality.
- the presentation of the correlated quality status report is preferably presented in the graphical or tabular form.
- the preferred embodiment of the status enunciator 100 is either a graphical display monitor such as a LCD or CRT monitor.
- the status indicator could be implemented as printer device capable of generating printed hardcopy reports of the correlated quality status reports.
- the ability to graph current or historical defect rates as a function of machine entity is a primary output of this class of machine vision system in addition to the fundamental notification or rej ection of defective containers.
- FIG. 4 provides a schematic outline of an alternate embodiment of the disclosed invention.
- a multi-channel camera 170 is used to obtain both the defect attribute and container code image information.
- Multi-channel cameras are well known in the art (typically implemented as Red/Green/Blue RGB cameras). Cameras of this type use spectral filtering techniques within the camera housing to separate the received image information into multiple video channels.
- Figure 5 provides a schematic outline of yet another alternate embodiment of the disclosed invention.
- a single, high-speed camera 180 is used in conjunction with an imaging lens 70 to sequentially acquire both a defect attribute image and a container code image for each container 20 that passes through the inspection zone 130.
- High scan rate cameras 180 as discussed herein are well known in the art.
- CMOS imagers are commercially available that support the integration and clocking-out of image data within 2 milliseconds. Image acquisition speeds of this magnitude support the prospect of capturing 2 independent images for the same part using the same camera 180 as the part passes dynamically through the inspection zone 130.
- CMOS imagers support configurable signal integration times that can be changed on the fly. This, in combination with on-the-fly configurable solid-state illumination support the acquisition of both a preferred defect attribute image as well as an out of saturation container code image without requiring the use of filters or beam splitters.
- the containers that are contemplated for inspection under the teachings of the present invention are formed with the container code included in a surface thereof using any of a variety of techniques that are well known, including those specifically mentioned herein.
- the forming of the code in the surface of the container occurs prior to the container being conveyed into the inspection zone. Once conveyance begins, the container 20 under test (and having the container code 10 thereon) is eventually detected approaching an inspection zone 130 (step 205).
- the image processor 80 performs detailed time- or movement-based positioning of the container 20 under test to place it in the center of an inspection zone 130 (step 210).
- the image processor 80 then sends control signals to the cameras 40 associated with both the defect attribute data and the container code data as well as to the solid-state illuminator 50. This starts the image acquisition process (step 215).
- the solid-state illuminator 50 acts to illuminate the container 20 under test with illumination fields (step 220).
- the light originates in an area near the lens of the imaging system to provide reflected illumination of the interior of the container (e.g. front lighting as opposed to transmissive backlighting).
- Light reflecting 141 off the container 20 under test is then separated into 2 channels, the defect attribute channel and the container code channel, by a beam splitter 30 (step 225).
- the reflected image data associated with both the defect attribute channel as well as the container code channel is received by an imaging lens 70 (step 230).
- Two images are simultaneously formed by suitable spatial light recorders contained within the system's cameras 40 (step 235).
- Image data obtained by the cameras 40 are sent to a image processor 80 (step 240).
- the image processor 80 processes the raw data into quality status information related to the container 20 under test (step 245). Included in the status information related to the container 20 under test is data relating part quality to the specific body maker, press, trimmer or other machinery that formed the part, based on the container code of the part.
- the image processor 80 sends the quality status information related to the container 20 under test to a status enunciator 100 (step 250).
- steps 225, 230, 235 and 240 may well be modified or replaced with steps designed to allow cameras 170, 180 to receive reflected light and appropriately provide data to the processor 80 (consistent with that which is described in connection with Figures 4 and 5). It should be further appreciated that all such methods (and the corresponding systems) according to the present invention may be implemented using a variety of software techniques and hardware implementations that will vary from implementation to implementation.
