Brown Machine Announces New Servo Driven LS-Model Horizontal Trim Presses
Beaverton, MI - Brown Machine LLC announces the addition of a servo driven LS Model
to their current line of T-Series line of horizontal trim presses. With the moving platen movement controlled through a servo drive, this press has the capability of slowing down for a controlled long ejection into product handling systems, speed up to make up the loop, and then maintain cycle time with the thermoformer. This press is available in models with sheet widths of 33", 53", 58", 68", and 74". A leading producer of cold and hot drink lids will take delivery of the first unit in June 2006.
Twenty-two inch (22") diameter drive sheaves replace the traditional thirty-two inch (32") diameter flywheels on the standard L-Model horizontal trim presses reducing the inertia by over 80%. This allows the drive to efficiently slow the press in one cycle to accomplish the ejection cycle, then quickly ramp back up in speed. In fact, the press has to run faster to make up the accumulated product from the slow down cycle before adjusting back to the production speed that maintains consistency with the thermoformer. A powerful Yaskawa servo motor and drive system replaces the variable frequency motor and drive. The servo system is not only required to control the speed profiles but must also provide the power to produce the tonnage lost by the flywheel inertia. The servo system is connected to the drive sheaves by multiple "C" belts for efficient transfer of power and control. By using the drive sheave concept, the press design maintains the ability of having multiple crank throw locations for 4.5", 7.5", 10.5" or 13.5" stroke selections.
As with the L-Model trim presses, platen movement is precisely guided with eight linear
bearings on the moving platen, however the window to side load trim tools has been greatly expanded to 37" on LS-Models from 25" on standard L-Models. This opening offers side load capabilities to producers of cold and hot drink lids, food and berry box containers, horticulture containers and other products that traditionally have pre-punch straw slot, sip holes, vent slots or drain holes. The moving platen is also taller to support these progressive trim tools.
Designed principally for high speed trim applications, the press incorporates a new
designed counterbalance system. The counterbalance platen is linear guided in a horizontal motion with four linear bearings positioned on the bottom of the platen. The motion is actuated via an eccentric from the main shaft that counteracts the motion and weight of the moving platen with trim tooling. Additional trim press frame supports are also added to the front of the press for stability. These features provide a smooth and stable trim press motion when operating at high speeds.
Standard models are controlled with a CTC Parker Human Machine Interface (HMI) that
communicates with a Yaskawa machine control system. This machine control incorporates
multi-axis motion control for the main drive, feed and eject servo systems, and PLC control for the remaining machine functions. As an option, Brown's new Series 4.0 Controls are available with the Operator Interface incorporating non-proprietary National Instruments Lookout software. Menu-based color displays provide ease of navigation and machine control throughout the HMI.
Leaders in Trim Press technology
With both T-Series horizontal and V-Series vertical trim press configurations designed
to meet your specific application, Brown offers the widest selection in trim press technology. In addition to this new servo driven LS-Model, Brown offers linear guide flywheel driven horizontal trim presses in our standard L-Models, along with LP and LDP Models incorporating extended stroke for deep draw products requiring progressive trim applications. Servo driven vertical trim presses can be used as either an intermediate trim press for prepunch applications or as a perimeter trim press to trim, count, accumulate and transfer precounted stacks of products.
