Commonwealth of Pennsylvania Pennsylvania Department of Transportation Specification for a Flat-Bed Table Cutter/Plotter for a Computerized Signmaker System 1. General. A large, rigid flat-bed vacuum table top with a precision cutter/plotter controlled by sign design computer software, to: (1) draw sign designs on paper using a variety of pens; or (2) cut vinyls such as transparent, opaque, and retroreflective sheeting materials for the fabrication of traffic signs. Construction. 2.1 Frame. The flat bed table to have a heavy steel frame to form a torsion-proof unit with a wide vacuum chamber tabletop. The table top to remain flat and free of vibrations. 2.2 Vacuum Table Top. A minimum of five individually adjustable vacuum zones to securely hold paper, retroreflective sheeting materials, transparent and opaque films, and other materials while sign legend and graphics are drawn or cut. 2.3 Automatic Material Advance System. A motorized, sensor-controlled material advance system with a feed loop, capable of being controlled either manually from the operator’s console or automatically via software. The system to be capable of handling a minimum 150-foot long roll of retroreflective sheeting, up to 48 inches in width. The system to include a minimum of four positional vacuum pods to lift and advance the material on the tabletop. 2.4 Cutter/Plotter Drives. Solid rack and pinion drives connected to strong servo motors to transform the commands of the intelligent multi axis microprocessor control into smooth and precise movements at speeds of up to 45 inches per second and an accuracy within 0.008 inch. 2.5 Microcomputer and Memory Expansion Board. The microcomputer to control, supervise and store movement settings and data, and to optimize data sent from a connected computer (not included). The memory expansion board to include a minimum 2MB data buffer for repetition of plots. 2.6 Cutting and Plotting Head. Provide all-in-one standard and pneumatic controlled head with servo controls.
