“Tagged” by DualVee® Technology

Why did The Hillman Group choose Bishop-Wisecarver’s DualVee Guide Wheels for their application? Because DualVee was more cost effective compared to other rail technology, and allowed for better customization -- find out how this challenge was solved >>

Challenge: The increasing population of pets and the need for secure property identification inspired The Hillman Group, a hardware industry supplier of fasteners, key and key accessories, letters, numbers and signs, and numerous specialty and point-of-purchase items, to design a personal and pet identification tag engraving machine. Hillman was looking for a linear motion based system that could smoothly guide the engraving head as it moves back and forth, engraving the metal tag. The harsh metal chip environment, space and money constraints, and ease of integration were key factors when it came to choosing the right technology for this application.

Application Description: Mainly found in pet stores, the state-of-the-art QuickTag™ is a computer-driven, stand-alone machine that engraves personal identification and pet I.D. tags in less than two minutes. The customer first chooses a tag style and text from a video touch screen above the engraver and then watches it being made through an observation window. A blank metal tag is dispensed into a designated slot depending upon its size and shape. The engraving head automatically positions itself above the tag and engraves the information typed in from the touch screen.

Solution: DualVee® wheels, track and bushings were chosen to help guide and position the engraving head as it moves back and forth over the metal tags. DualVee allowed the application design to be more custom and compact due to its seamless integration and easy configuration into the machine. It also proved to be more cost effective compared to other rail technology. DualVee’s smooth motion and ability to wipe flying metal chips away from the track were important features that allowed the application to produce quality engraved tags.

Products Used: Size 2 DualVee guide wheels, track and bushings

HepcoMotion® GV3 Immune to Glass Dust Ingress

Why did CRT Heaven choose Bishop-Wisecarver’s HepcoMotion GV3 linear system for their heavy duty application? Because production and efficiency increased -- find out how this challenge was solved!

Challenge: Sub-5 micron glass dust was playing havoc on the ball race linear bearings used on a cathode ray tube (CRT) screen splitting recycling system. Dust was infiltrating the travel table bearings and transport assembly which caused a build-up of glass and, ultimately, premature failure. CRT Heaven, manufacturer of the CRT Angel machine, required a linear bearing assembly solution that would minimize downtime and maintenance and withstand significant forces imposed by CRTs weighing up to 60kg with glass up to 15mm thick.

Application Description: The CRT Angel is a highly efficient machine that accurately separates the unleaded glass portion from the leaded glass portion of television and monitor tubes. The machine has six pre-programmed cut cycles to handle the variety of CRT shapes and sizes. The CRT is mounted to a travel table and laterally transported between diamond cutting blades for the initial cut, then it’s rotated 90ยบ and cut again, completing the separation of the two glass portions. The internal and external components of the CRT are then removed for proper disposal. The machine processes per hour an average of 120 IT monitors and 80 CRTs varying in sizes from 6” to 42”.

Solution: CRT Heaven chose the HepcoMotion GV3 linear system because of its similar profile to the flat rail and ball race bearings already installed on the machine, and its ability to handle the aggressive, dust-laden environment. The GV3’s all-steel slideway’s rugged construction makes it ideal for this heavy duty application. GV3 was also chosen for its unique wiping action which expels the fine glass dust, preventing it from compromising bearing performance. According to the project manager at CRT Heaven, after one and a half years in use, only one of the 48 journals had to be replaced, and only because a foreign object inadvertently left on the machine. Without a doubt, the longevity, performance, and ease of installling and servicing the bearing assemblies has helped increase the production and efficiency of the CRT Angel.
