20080243306 | CONTROL DEVICE OF WORK POSITIONING APPARATUS - A control device of a work positioning apparatus includes an operating limit line storage unit for storing position coordinates of an operating limit line, a speed reduction zone storage unit for storing a width of a speed reduction zone ranging from a reduction start position to the operating limit line, a check point storage unit for storing position coordinates of check points set in the work, a check point updating unit for determining position coordinates of the check points moved in accordance with an operation of the work positioning apparatus by calculation, an in-speed-reduction-zone determining unit for determining whether the check points enter the speed reduction zone in accordance with the updated position coordinates of the check points, and a work positioning apparatus control unit for instructing a work positioning apparatus motor to reduce a speed if the check points are determined to enter the speed reduction zone. | 10-02-2008 |
20090107969 | ARC WELDING ROBOT CONTROL SYSTEM AND METHOD THEREOF - An arc welding robot control system of the present invention includes memory devices, controlling devices, a welding condition changing position calculating device, a weaving operation controlling device that outputs a signal of completion of one weaving cycle every time when a welding torch completes to perform one weaving cycle of a predetermined movement pattern, a welding condition calculating device for calculating to-be-changed welding conditions, and a welding condition changing device that changes welding conditions of an arc welding robot, based on to-be-changed welding conditions, every time when a signal of completion of one weaving cycle is input. With this configuration, it enables a continuous change of welding conditions and a copying arc welding with high accuracy even in the case in which the arc welding robot performs a weaving operation. | 04-30-2009 |
20110198331 | TIP-BASE METAL DISTANCE CONTROL METHOD FOR ARC WELDING SYSTEM, AND ARC WELDING SYSTEM - A tip-base metal distance control method includes an actual-welding-current acquisition step of measuring actual welding currents by current measuring means under a predetermined actual welding condition and calculating an average actual welding current under the actual welding condition by average-value calculation means, a reference-current acquisition step of extracting, from a reference-current storage table, an average actual welding current corresponding to the actual welding condition and setting the average actual welding current as a reference current by reference-current acquisition means, a current comparison step of comparing the average actual welding current under the actual welding condition with the reference current by current comparison means, and a welding-torch-position correction step of correcting the position of a welding torch in an upward or downward direction by welding-torch-position correction means on the basis of a comparison result in the current comparison step. | 08-18-2011 |
