摘要： A system for selectively loading the lowermost segment of a shingled stack of limp material segments, where each segment includes one or more adjacent layers of said limp material, and wherein adjacent segments of said stack are laterally offset along a reference axis. The system includes a substantially planar surface adapted to support the shingled stack thereon, in a position so that the leading edge of the lowermost segment is adjacent to a reference point along the reference axis. A selectively operable extractor transports the lowermost segment in the direction of the reference axis and away from the stack. The extractor includes one or more sets of hinged jaws positioned for movement in the direction of the reference axis between the reference point and a point displaced from the reference point along the reference axis. The sets of jaws are adapted to selectively grip a portion of the leading edge of the lowermost segment when that leading edge is adjacent to the reference point.

摘要： Three-dimensional measurement of a surface of an object under inspection is performed by projecting a light pattern upon the surface, having a periodic, smoothly varying light intensity in the X direction and having a non-changeable intensity in the Y direction in the manner of a grid, and thereafter electronically producing a pair of stereo images of the surface so illuminated by a pair of CCD arrays; measuring the parallax phase offsets between correlated corresponding homologous points in the stereo images, and converting the resulting parallax data to an array of Z-depth data, indicative of the shape of the surface of the object. A single left and right stereo snapshot is simultaneously obtained, so that relative motion between the object and the field of view has no adverse effect on accurate measurement, and the solid state light detection arrays are fully offset in an outboard direction with respect to the principal optical viewing axes, so that a stereo-based distance is provided which may be maximized to obtain more accurate measurements.

摘要： A propeller grinding device and method employs two endless grinding belts which are transported past a grinding station to finish the front and back surfaces. A propeller blank is inserted between the belts and the belts are distorted by platens, each of which includes a plurality of independent platen vanes. Two cams selectively bear upon two camming surfaces of the vanes and move the vanes into desired positions corresponding to the surface contours to be formed on the front and back surfaces of the propeller blades. The cams are rotated as the blade is moved. They also may be moved along the camming surfaces. Additionally, the cams and platens may be moved parallel to the direction of cam rotation with respect to the belts. SUBACKGROUND OF THE INVENTIONThe present invention relates to grinding devices and, more particularly, to a grinder having an endless grinding belt capable of grinding contours, such as the airfoil shape of a propeller.Belt grinders have been used in the past for finishing a flat surface. U.S. Pat. No. 2,706,873, issued Apr. 26, 1955 to Gifford, shows a sanding device having an endless sanding belt, which belt is continuously rotated and urged into contact with the workpiece by a plurality of rollers. U.S. Pat. No. 3,129,535, issued Apr. 21, 1964, shows a similar grinding arrangement in which two grinding belts grind opposite sides of the workpiece simultaneously. This eliminates the need for backing arrangements opposite the belts to offset the grinding forces applied by the belt mechanisms.U.S. Pat. No. 3,670,458, issued June 20, 1972, to Faure, shows a multiple-position grinding arrangement in which a plurality of workpieces are ground simultaneously. Cam mechanisms are used to present the workpieces in predetermined attitudes to the grinder and to alter the orientation of the grinding belts.As shown in U.S. Pat. No. 2,723,505 issued Nov. 15, 1955 to Krafft, the flexibility of a grinding belt may be utilized advantageously to grind predetermined contours as well as flat surfaces of a workpiece. In the Krafft devices, a repetitive pattern is ground by using an appropriately contoured metal roller as the backup roller for a flexible abrasive belt. The contoured metal roller of the Krafft device is rotated at the same speed as the abrasive belt.It has been recognized that a need exists for a machine capable of grinding relatively complex contours. One approach, shown in U.S. Pat. No. 3,049,839 issued Aug. 21, 1962 to Smith, and U.S. Pat. No. 3,859,757 issued Jan. 14, 1975 to Heesemann, is to provide a flexible plate as the platen for the abrasive belt at the grinding station. This flexible plate can be distorted in shape to the appropriate contour. Both the Smith and Heesemann machines use a plurality of air-actuated cylinders for distorting the flexible platens. The dimensions of such cylinders, however, necessitate the use of relatively few cylinders across the width of the abrasive belt, thereby limiting the complexity of the contour which may be ground.U.S. Pat. No. 3,685,219 issued Aug. 22, 1972 to Palmenberg, discloses another approach to altering the contour of a driven abrasive belt. In the Palmenberg patent, a patent is provided having a plurality of air holes. Pressurized air is forced through these holes and generates an air cushion against which the abrasive belt is urged. The Palmenberg device is said to be particularly useful in grinding the airfoil shapes of a turbine vane.U.S. Pat. No. 2,426,764 issued Sept. 2, 1947 to Czarnecki, shows a machine useful in finishing propeller blades. An abrasive belt is moved past a cam which defines the desired airfoil shape at the grinding station. The cam is rotated in synchronism with the movement of the propeller blade past the grinding station such that the contour being ground is changed continuously. The cam acts directly upon the back of the abrasive belt, with an intermediate rubber cusioning belt provided in between.None of the belt grinders disclosed above provide an arrangement for grinding a range of airfoil shapes without substitution of machine parts. While Czarnecki does permit a continuous abrasive belt grinding operation for a propeller blade, the contour roller acts directly upon the abrasive belt so that only a single propeller blade size can be machined with a given roller. Additionally, the roller tends to wear, even when an intermediate belt is positioned between the back of the abrasive belt and the roller.SUMMARY OF THE INVENTIONA contour grinding device has a grinding belt which is movable past a grinding station and a platen adjacent the belt for distorting the belt into a desired contour. The platen includes a plurality of independently movable platen vanes which define a first camming surface. A cam means including a first cam bears upon the first camming surface for moving the vanes into desired positions. Means are provided for moving the cam means with respect to the vanes such that the relative positions of the vanes may be altered. A wear-preventing belt, interposed between the platen vanes and the grinding belt, is moved periodically and minimizes the wear of the vanes by the grinding belt.A second camming surface may be provided on the vanes, with a second cam in contact therewith. Means are provided for moving the second cam into contact with the second camming surface as the first cam is moved out of contact with the first camming surface, to provide an unbroken transition in contour on the workpiece. Both the first and second cams may be rotated as well as moved along their respective camming surfaces. The cams and the platen may also be moved with respect to the grinding belt in a direction which is parallel to the axis of cam rotation.A dual belt grinding machine having first and second endless grinding belts may be provided in which the contour shapes of the belts are controlled by corresponding first and second belt platen means. Each platen means includes a plurality of vane members and dual cams which bear upon each of the vane members and which urge the belts into the desired contours.Accordingly, objects of the present invention are to provide a contour grinding device and method in which an endless grinding belt grinds the desired shape for a workpiece, in which the contour to be ground is determined by a cam acting upon a plurality of vanes, which vanes in turn form a platen acting upon the belt; in which the cams may be rotated as the workpiece is moved and translated with respect to the vanes such that a plurality of contour surfaces may be specified; and in which dual endless grinding belts simultaneously act upon opposite sides of the workpiece.It is also a particular object of the invention to provide a method and apparatus for the finishing of the contour of aluminum propeller blades from forged propeller blanks, to apply by, profile grinding, the inboard and outboard airfoil sections of the blade simultaneously along the front and back surfaces of the blade to provide for the smooth transition between the inboard and outboard sections, and to control accurately and automatically the amount of material removed from the blank so as to form a finished or substantially finished blank.A further object of this invention is the provision of a controllable grinding apparatus provided with a pair of grinding belts together with a multiple element platen for controlling the contour of the belts at a grinding station for the purpose of forming in a blank or a workpiece contours simultaneously on upper and lower surfaces thereof, such as the forming of the airfoil shape on an aluminum propeller blade, as outlined above.It is also an object of this invention to provide a method of removing metal from a blank, such as a propeller blade blank, involving the steps of moving belt grinding surfaces in opposed relation at opposite sides of a grinding station, moving a propeller blade blank between the grinding surfaces in contact therewith at the grinding station in a spanwise direction and simultaneously altering the contour of the belt surfaces at the grinding stations with the movement of the blank, so that the surfaces of the blank at the grinding station are finished. The method may provide the further steps of moving the blank in rotation during grinding or otherwise tilting or moving the blank to accommodate for the twist of the blade, the tilt of the blade, and/or the sweep of the blade.These and other objects and advantages of the invention will be apparent from the following description, the accompanying drawings, and the appended claims.
