The subject matter herein relates generally to reel handling machines.
Cardboard reels are used commonly in manufacturing lines to store raw materials and finished goods. For example, electrical contacts, arranged along a carrier strip, may be wound on a reel as a product strip. The product strip is unwound into a machine, such as a termination machine or leadmaker machine to terminate the contacts to wires or leads or a contact loading machine to load the contacts into a connector housing. The machines require that the product strip be wound in a particular winding direction. However, some machines require the product strip be wound in a clockwise direction and other machines require the product strip be wound in a counterclockwise direction. Rewinding the reels to change the winding orientation is a time consuming process. Currently most of the tasks are done by human, which requires much labor and have safety concerns.

In an exemplary embodiment, the adhesive unit 192 includes a dispenser 194, such as a nozzle, for dispensing the adhesive. In an exemplary embodiment, the dispenser 194 is movable relative to the re-reel mount 170. For example, the tip of the dispenser 194 may be variably positionable relative to the re-the reel mount 170, such as to accommodate different lengths of product strip 102 on the reel 110 and/or to accommodate reels having different outer diameters. In an exemplary embodiment, the adhesive unit 192 is automatically operated, such as to automatically dispense the adhesive onto the paper interleaf as the paper interleaf is wound onto the reel 110. Operation of the adhesive unit 192 may be controlled based on input from the product strip detector 190.
In an exemplary embodiment, the reel handling machine 100 includes a reel manipulator 200 positioned proximate to the re-reeling assemblies 140. In an exemplary embodiment, the reel manipulator 200 is coupled to the frame 120, such as being coupled to the platform 132. However, in alternative embodiments, the reel manipulator 200 a be movable relative to the frame 120. For example, the reel manipulator 200 may be included on a mobile transport device, such as an automated guided vehicle (AGV). The reel manipulator 200 is used to remove the rewound reel 110 from the re-reel mount 170 after the product strip 102 is rewound on the reel 110. The reel manipulator 200 is used to move the rewound reel 110 to one or more processing stations for further processing. For example, the reel manipulator 200 may move the rewound reel 110 to a taping station 220 to apply tape to the reel 110. The reel manipulator 200 may additionally, or alternatively, move the rewound reel 110 to an inspection station 230 to inspect the reel 110. The reel manipulator 200 may additionally, or alternatively, move the rewound reel 110 to a labeling station 240 to apply a label to the reel 110. The reel manipulator 200 may additionally, or alternatively, move the rewound reel 110 to a stacking station 260 or other completion station after the reel 110 has been processed, such as for transportation away from the reel handling machine 100.
In an exemplary embodiment, the reel manipulator 200 includes a robotic arm 202 is movable in three-dimensional space. The robotic arm 202 has a reel handler 204 at the end of the robotic arm 202. The reel handler 204 is used to hold the reel 110. In various embodiments, the reel handler 204 may include latches, clips, fasteners or other securing features to secure the reel 110 to the reel handler 204. In other various embodiments, the reel handler 204 may include vacuum cups, suction cups, or other securing features to secure the reel 110 to the reel handler 204. In various embodiments, the reel manipulator 200 is configured to hold the reel 110 in various orientations, such as vertically, horizontally, or at other angles. In various embodiments, the reel manipulator 200 is configured to hold the reel 110 in various angular positions. For example, the reel manipulator 200 may rotate the reel 110 to various angular positions.
In use, the reel manipulator 200 automatically picks up the reel 110 after the product strip 102 is rewound onto the reel 110. For example, a signal may be sent to the reel manipulator 200 when the winding process is complete triggering the reel manipulator 200 to pick up the reel 110 from the re-reel mount 170 of the corresponding re-reeling assembly 140. The reel manipulator 200 then moves the reel 110 to the taping station 220 where tape is applied to the outer perimeter of the reel 110. The reel manipulator 200 then moves the reel 110 to the inspection station 230 for visual inspection, such as by a vision inspection system. The inspection station 230 may inspect the reel 110, such as to inspect the tape applied to the outer perimeter of the reel 110 and/or the location of any label on the reel 110 and/or the data on the label. The reel manipulator 200 then moves the reel 110 to the labeling station 240 where a label may be applied to the side of the reel 110. In an exemplary embodiment, the label is applied over the existing label to cover the existing label, the location of which was determined at the inspection station 230. The reel manipulator 200 may orient the reel 110 at the labeling station 240 to ensure that the label is applied to cover the previous label. For example, the reel 110 may be rotated to a particular orientation such that the label can be applied over the existing label. The reel manipulator 200 then moves the reel 110 to the stacking station 260 to drop off the reel 110 at the stacking station 260. The reel manipulator 200 is then ready to pick up the next reel 110 from the re-reeling assemblies 140.
In an exemplary embodiment, the taping station 220 includes a tape applicator 222 coupled to the frame 120. For example, the tape applicator 222 may be coupled to the platform 132. The tape applicator 222 applies tape to the outer periphery of the reel 110. For example, the tape may be applied to the outer side surfaces of the flanges 114 and span across the gap between the flanges 114. The tape may prevent the product strip from inadvertently unwinding from the reel 110. In an exemplary embodiment, multiple segments of the tape are applied at different locations around the outer periphery of the reel 110. For example, four segments of the tape may be applied at 90° intervals apart from each other. Greater or fewer segments of the tape may be applied in alternative embodiments. In an exemplary embodiment, the reel manipulator 200 rotates the reel 110 at the taping station 220 to change the orientation of the reel 110 relative to the tape applicator 222, such as to apply the tape at different portions of the reel 110. In alternative embodiments, a continuous piece of tape is applied circumferentially around the outer periphery of the reel 110.
In an exemplary embodiment, the inspection station 230 includes an imaging device 232 for imaging the reel 110. The imaging device 232 may be a camera. The imaging device 232 may image the product strip 102 wound on the reel 110 and/or may image the tape applied to the reel 110 and/or may image other portions of the reel 110, such as the flanges 114. The images are analyzed to detect problems or flaws. In an exemplary embodiment, the imaging device 232 images the side of the reel 110 to detect a location of a label on the reel 110. For example, because the reels 110 may be reused, previous labels may be present and need to be removed or covered up. The location of the label may be determined to control operation of the reel manipulator 200, such as to cause the reel manipulator 200 to rotate the reel 110 a determined angular distance for positioning the reel 110 at the labeling station 240 (for example, to align the existing label within the labeling station such that the new label covers up the old label). In alternative embodiments, the reel manipulator 200 may rotate the reel 110 at the inspection station 230 until the old label is at a predetermined angular position relative to the imaging device 232 (for example, at 0° or another angular position), wherein the angular position is maintained by the reel manipulator 200 as the reel 110 is moved from the inspection station 230 to the labeling station 240. In other alternative embodiments, the inspection station 230 may be located at the labeling station 240 such that the reel 110 is not moved between the stations, but rather is properly oriented within the labeling station 240 using the imaging device 232. In various embodiments, multiple inspection stations 230 may be provided, such as at other stations (for example, at the taping station 220).
In an exemplary embodiment, the labeling station 240 includes a label printer 242 and a label applicator 244. The label printer 242 prints a new label for the reel 110. In various embodiments, information printed on the label printer 242 may be based on data gathered by the imaging device 232. For example, the system may determine the wind direction based on the image and/or may determine the type of product strip 102 based on the image and/or may determine the size or type of contact on the product strip 102 based on the image and/or may determine the size of the reel 110 based on the image and/or may determine other data based on the image, such data being used to generate the information printed on the label by the label printer 242. The label applicator 244 applies the label printer by the label printer 242 directly onto the reel 110. In an exemplary embodiment, the label applicator 244 applies the label in the same location as the existing label to cover the existing label. In various embodiments, the reel manipulator 200 positions the reel 110 relative to the label applicator 244 such that the new label is applied at the proper location to cover the old label. In various embodiments, the label applicator 244 is a roller applicator. In other various embodiments, the label applicator 244 includes a vacuum gripper configured to pick and place the label onto the reel 110. Other types of label applicators may be used in alternative embodiments.
In various embodiments, after the label is applied to the reel 110, the reel manipulator 200 may position the reel 110 at the inspection station 230 to image the newly applied label. The image is analyzed to determine proper application of the label to the reel 110. The image is analyzed to determine that a single label is visible on the reel 110. The image is analyzed to determine that the correct information is printed on the label.
In an exemplary embodiment, the reel manipulator 200 moves the labeled reel 110 to the stacking station 260. The reel 110 is placed on a reel stack 262 and released by the reel manipulator 200. In various embodiments, the reel stack 262 may be stacked on the platform 132. Optionally, the reel stack 262 may be stacked on a pallet for removal from the platform 132. After the reel 110 is released by the reel manipulator 200, the reel manipulator 200 is able to pick up the next reel 110 from the re-reeling assembly 140.
In an exemplary embodiment, the reel handling machine 100 includes a controller 300 for controlling the automated processes of the reel handling machine 100. The controller 300 may be operably coupled to the reel manipulator 200 and/or the tape applicator 222 and/or the imaging device 232 and/or the label printer 242 and/or the label applicator 244. The controller 300 may be operably coupled to the drive mechanisms 166, 176 of the re-reeling assembly 140. The controller 300 may be operably coupled to the adhesive unit 192 of the re-reeling assembly 140. Control of the various components may be controlled based on inputs or signals from other components.
In an exemplary embodiment, the controller 300 is operably coupled to a user interface 310. The user interface 310 may include a display 312 and one or more inputs 314, such as buttons, dials, touchscreens, pointer devices, and the like. In the illustrated embodiment, the user interface 310 is coupled to the frame 120, such as through the labeling station 240. In alternative embodiments, the user interface 310 may be a mobile device, such as a laptop or other handheld device. The operator may control various operations of the reel handling machine 100 through the user interface 310. For example, control signals may be transmitted to the controller 300 to control the other automated components of the reel handling machine 100.
At the first re-reeling assembly 142, at step 402, two of the reels may be manually loaded into the first re-reeling assembly 142. For example, a full reel may be manually loaded onto a reel mount and an empty reel may be manually loaded onto a re-reel mount. During manual loading, the operator physically picks up the reels and attaches the reels to the mounts. The end of the product strip is partially unwound and routed through guide features, such as the guide rollers to the empty reel. In an exemplary embodiment, the paper interleaf at the end of the product strip is routed through the guide features to the empty reel. The end of the paper interleaf and/or the end of the product strip are partially, manually wound onto the empty reel. At step 404, the product strip is automatically re-reeled from the first reel onto the second reel. Drive mechanisms are used to rotate the mounts, and thus the reels, during the automatic re-reeling. In an exemplary embodiment, a vision system is used to monitor the product strip during the re-reeling process, such as to detect splices, damage, and the end of the product strip. Signals from the vision system may be used to control the re-reeling process, such as to control the speed of the drive mechanisms and/or to stop the rotating of the mounts when damages detected and/or when the end of the product strip is detected. At step 406, a paper interleaf is secured to the end of the product strip and secured to the winding to hold the product strip in the wound condition on the reel. The first re-reeling assembly 142 may include an adhesive dispenser to secure the paper interleaf on the winding.
At 410, the system signals completion of the rewinding process on the reel. Such completion signal triggers the next phase of processing of the reel. At 412, the system activates a reel manipulator to remove the rewound reel and transport the reel to the reel processing station 146. After the reel is removed, at 414, the system signals that the first re-reeling assembly 142 is ready for manual reloading.
The second re-reeling assembly 144 may be operated in the same manner as the first re-reeling assembly 142. At the second re-reeling assembly 144, at step 422, two of the reels may be manually loaded into the second re-reeling assembly 144. For example, a full reel may be manually loaded onto a reel mount and an empty reel may be manually loaded onto a re-reel mount. During manual loading, the operator physically picks up the reels and attaches the reels to the mounts. The end of the product strip is partially unwound and routed through guide features, such as the guide rollers to the empty reel. In an exemplary embodiment, the paper interleaf at the end of the product strip is routed through the guide features to the empty reel. The end of the paper interleaf and/or the end of the product strip are partially, manually wound onto the empty reel. At step 424, the product strip is automatically re-reeled from the first reel onto the second reel. Drive mechanisms are used to rotate the mounts, and thus the reels, during the automatic re-reeling. In an exemplary embodiment, a vision system is used to monitor the product strip during the re-reeling process, such as to detect splices, damage, and the end of the product strip. Signals from the vision system may be used to control the re-reeling process, such as to control the speed of the drive mechanisms and/or to stop the rotating of the mounts when damages detected and/or when the end of the product strip is detected. At step 426, a paper interleaf is secured to the end of the product strip and secured to the winding to hold the product strip in the wound condition on the reel. The second re-reeling assembly 144 may include an adhesive dispenser to secure the paper interleaf on the winding.
At 416, the system signals completion of the rewinding process on the reel. Such completion signal triggers the next phase of processing of the reel. At 412, the system activates the reel manipulator to remove the rewound reel and transport the reel to the reel processing station 146. After the reel is removed, at 418, the system signals that the second re-reeling assembly 144 is ready for manual reloading.
At 430, the reel manipulator moves the reel to a tape applicator to apply tape across the flanges of the reel. At 432, the reel manipulator moves the reel to a label applicator to apply a label to a side of the reel. At 434, the reel manipulator moves the reel to a reel stack to unload the finished reel onto the reel stack. The reel processing station 146 may include an imaging device that images the reel before and/or after processing at the various steps. For example, the imaging device may image the reel prior to tape application or post tape application. The imaging device may image the reel prior to label application or post label application. The imaging device may image the reel prior to unloading at the reel stack. The reel may be further processed and/or manipulated by the reel manipulator based on the images by the imaging device.
