Cutting system for slab-type materials

Abstract

A cutting system for slab goods is disclosed. The system has three stations operating under computer interface control. In a first station, slab goods, such as synthetic shoe bottom materials and the like, are sequentially loaded for purposes of measurement. At the measuring station, the material is loaded on a slab-by-slab basis, and for each slab of material, a series of measurements are made to determine the largest permissible rectangle for that irregular piece of material. The dimensions are fed to a marker-making system, which, in real time, determines the average of usable material taken from the measurements of all the stacked slabs. A cutting marker is then generated by the marker-making system. The slabs are then moved into the cutting area, utilizing a belt drive upon which the slabs rest in the measurement station. Cutting commences at the cutting station, utilizing a cutting tool mounted on a carriage which traverses that station. A variable hold-down system accommodates different size slabs. When the cutting is complete, material is transported to an off-load station where the cut parts are removed from the system. Flowthrough is achieved by having three discrete stations working independently such that, for example, while measuring is taking place at the measure station, cutting may simultaneously occur at the cutting station and prior cut goods being off-loaded at an off-load station. Additionally, multiple cutting systems may be controlled by a single marker-making system.
