Patent number: 4189337Abstract: A real time system for writing and depositing a label on a cut piece is disclosed. The labeler is positioned relative to the cutting head of a cutting system and moves with the cutting head as a cutting operation proceeds. As the cutting takes place under the direction of the cutting system computer, a label is printed by a printer mechanism and is deposited at the appropriate time for placement on top of the cut part. Printing is by a print head having computer input and control for the indicia printed. Label depositing is effectuated by first stripping the printed label from its backing strip and holding it in place on a vacuum head. The head is lowered to a position inside the cutting head dish. At an appropriate time, the pressure is reversed such that the vacuum dissipates and a positive pressure blows the label off the head downward onto the correct part. The sticky backing on the label holds it in place on the part.Type: GrantFiled: April 10, 1978Date of Patent: February 19, 1980Assignee: Camsco, Inc.Inventors: Bobby L. Higgins, Jerry Comer

Patent number: 4186632Abstract: 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.Type: GrantFiled: July 7, 1978Date of Patent: February 5, 1980Assignee: Camsco, Inc.Inventors: Elmer N. Leslie, Bobby Higgins, Joe T.

Patent number: 4170419Abstract: The specification discloses an optical web inspection system for detecting imperfections in a web having a longitudinal axis and moving in a plane across an inspection area. Radiation means is disposed above the plane of the web and transverse to the longitudinal axis of the web for directing radiant energy on the web at the inspection area. A plurality of sensors are mounted transverse to the longitudinal axis of the web and above the inspection area for receiving reflected radiation from successive transverse portions of the web passing across the inspection area. The plurality of sensors generate electrical output signals representing the intensity of the reflected radiation from the successive transverse portions of the web. Circuitry for periodically summing the electrical output signals from selected ones of the sensors is provided to generate a summation signal representative of the sum of reflected radiation from selected discrete segments of a plurality of the transverse portions of the web.Type: GrantFiled: February 23, 1977Date of Patent: October 9, 1979Assignee: Camsco, Inc.Inventors: Richard G.

Patent number: 4162763Abstract: A high-pressure fluid jet valve assembly is disclosed utilizing a double-acting piston actuated by a spool valve to reversibly actuate the valve stem. The valve stem selectively gates high-pressure cutting fluid through a seat arrangement directly into an output expansion section. Directly coupled to the expansion section is a valve head holding a jewel holder used to shape the high-pressure fluid beam for cutting purposes. The valve seal, stem and seat arrangement are designed to prevent leaching of the stem by the effect of high-pressure water, yet allow the cycling time in the order of 25 milliseconds.Type: GrantFiled: January 10, 1978Date of Patent: July 31, 1979Assignee: Camsco, Inc.Inventor: Bobby L. Higgins

Patent number: 4150794Abstract: A high-velocity liquid jet cutting nozzle and housing for use with high-pressure fluid sources is disclosed. The nozzle housing eliminates the use of elastically deformable collars by having a nozzle mount of a material which yields only under the pressure of the liquid in the system. The nozzle mount extends downstream of the nozzle element and provides a yielding support, under pressure, for the nozzle element in the direction of fluid flow. The nozzle element, constructed from a jewel, typically sapphire, is thereby supported in a mounting element in a yieldable high-pressure seal when in operation. Different configurations can be used to produce a variety of cutting streams, depending on the material to be cut.Type: GrantFiled: July 26, 1977Date of Patent: April 24, 1979Assignee: Camsco, Inc.Inventor: Bobby L.

Patent number: 4140038Abstract: A fluid jet cutter utilizing a multitude of heads and flexible pressurized feed system is disclosed. The cutter utilizes a carriage which has mounted on it a plurality of fluid jet cutting heads which are maintained in registration with jet catchers operably disposed beneath the carriage. The cutters and jet catchers are movable either as a unit in synchronization with each other or moved separately to be spaced apart from a center head. Cutting in the Y-direction is effectuated by means of head movement along the carriage. Cutting action in the X-direction can be effectuated either by movement of the carriage or, alternatively, by movement of the cutting table bed. A tower disposed outside the cutting area is used to provide high pressure fluid to the cutting heads. The tower, with its flexible coupling, reduces the dynamic loads on the positioning system for the cutter heads, thereby allowing increased performance.Type: GrantFiled: January 11, 1977Date of Patent: February 20, 1979Assignee: Camsco, Inc.Inventor: Bobby L. Higgins
