Robotic Tip Changer (Weld Cap Exchanger)
The Kyokutoh Automatic KIKK Tip Changer is the safer and more efficient alternative to manual spot welding cap changes. Instead of an estimated 5–10 minute manual cap exchange cycle, a complete gun tip exchange takes as little as 25 seconds, including automated removal and placement verification.
Each electrode magazine holds 12 caps in 13, 16 and 19 mm diameters, with an easy no-tool locking system. Spare magazine cartridges are also available to minimize change cycle time.
Advantages of the KIKK
Labor cost savings and increased efficiency — Operators fill and replace magazines, but are no longer needed for every individual tip exchange. Magazine replacements take seconds with an easy toolless locking system.
More parts made — Kyokutoh tip changers require significantly less down time than manual cap changes. Instead of 5-10 minutes, the KIKK changes caps in as little as 25 seconds. The KIKK pays for itself by allowing increased throughput and productivity. (See the KIKK Tip Changer Efficiency Effects presentation for an example of downtime reduction and increased operational efficiency.)
Safety hazard decreases — Robotic tip changers keep operators out of the weld cell; they also lower the safety concerns with workers reaching in and around sharp and heavy objects.
Maximize cap life — Robotic tip changes aren't subject to an operator's schedule. The KIKK allows weld caps to be changed when needed — not too soon or too late — maximizing usage without sacrificing quality at the end of a cap's life.
Increased life of weld gun arms — Operators aren't using sharp tools and wrenching on the gun arm to remove caps. Kyokutoh tip changers don't "pull" on weld gun arms to remove the tip, or require the welder to rotate to remove the cap, like competitors' units. A pneumatic clamp grips and twists the cap until it separates (see video; Dropbox video links available upon request).
Can mount to end effectors — The KIKK can be easily mounted to an end effector (see second video above), unlike competitive tip changers, allowing the unit to service pedestal welders and stationary weld gun placements.
Kyokutoh's DH-SVR (below) is a dual-head servo-driven tip changer and dresser in a single unit. The DH-SV maintains Kyokutoh's no-tool locking system for fast magazine changes.
