DON’T JUST REBUILD –RETROFIT AND IMPROVE AT THE SAME TIME.
Sometimes the best, most economical way to enhance the performance capacity of a machine is to rebuild it. A US-based can manufacturing company began investigating the viability of rebuilding its existing production machinery – machines currently in use and in long-term ‘storage’.
Atlas Machine & Supply, Inc., a Louisville-based industrial services firm, bid on and won the project to completely rebuild the first of potentially several Bliss 1103 model Scroll Shears. These machines would typically be used in three-piece can manufacturing, sheeting metal into various lengths for the stamping process where sheets are formed into can components including top and bottom ends of cans and can bodies.
BLISS – GETTING THE JOB DONE FOR MORE THAN HALF A CENTURY
Bliss 1103 model Scroll Shears are quite old; they’re no longer manufactured yet the technology is tried and true. There are many of these machines in service to the can making industry, so customers typically repair them to keep them going. Some machines may be 40-50 or more years old, so a rebuild is no small feat.
While much of the technology was ‘tried and true’ many advancements had been made in the area of safety in the past 40+ years with the existing clutch and brake design being a prime example of areas that could be improved.
“ We can rebuild it. We have the technology. We have the capability: BETTER, FASTER, SAFER...”
SAFETY FIRST –BUT ENHANCED PRODUCTIVITY IS A CLOSE SECOND.
Atlas Machine was successful with their bid to rebuild this first machine, and as part of that rebuild process program, they took the initiative to recommend that rather than simply replacing the existing clutch and brake, they consider a GOIZPER Clutch-Brake Retrofit.
CHALLENGE:
Replace an old lever arm/air cylinder, multiple-disc clutch and a mechanically engaged drum brake from the 1950s, while simultaneously improving safety and efficiency at reasonable cost.
While staying ahead of OSHA safety regulations is smart business, the primary motivation in changing to the GOIZPER clutch-brake was to eliminate a very old design clutch and brake for commercial reasons.
• Old clutch and brake are very expensive to maintain, if you can even get the parts.
• To replace clutch parts you must pull the flywheel off the machine and remove the parts, reversing the operation when done.
SOLUTION:
Atlas selected a GOIZPER series 5.71.18 WD pneumatic clutch-brake combination.
In GOIZPER’s pneumatic clutch-brake combination the clutch and brake are in a single assembly; the clutch is pneumatically engaged and the brake is spring-engaged, pneumatically released. There is just one piston in the assembly. When the piston is pressurized the clutch is engaged, and when the pressure is removed from the piston, the brake engages.
• A truly fail-safe brake system
• OSHA friendly and compliant
• Very fast response times
• Parts are readily available
• Replace linings without removing the flywheel
A fully rebuilt, faster and safer Bliss Scroll Shear is ready for its next 50 years...
CONCLUSION:
Having successfully completed this assignment, Atlas Machine is working to rebuild the next group of Bliss Scroll Shears for the same client, while Torque Technologies is expanding its message and reach on the benefits of a GOIZPER clutch-brake retrofit.
WHY CONSIDER A RETROFIT?
• Avoid Obsolescence - Upgrade for access to new parts and components
• Increase Productivity - Increase uptime and production output while decreasing maintenance costs
Pneumatic Clutch-Brakes feature torque ratings up to 110,000 lb ft (150,000 Nm) so that they’re suited to a variety of heavy-duty industrial applications.
Hydraulic Clutch-Brakes feature a patented progressive double-piston design, eliminating shock loads associated with other high-pressure hydraulic systems. With Torque ratings up to 460,000 lb ft (633,000 Nm) they’re fit to meet the demands of your heaviest duty, industrial applications. Ideal for single stroking applications!
