摘要:
An imaging system includes a method and apparatus for use in processing fish body sections that have been transversely cut. The system uses a frame with a pair of shrouds, each having an interior space that contains an illumination system for illuminating the fish section. A pair of video cameras housed respectively within the shrouds scan opposed flat sides of the fish section to produce images of the respective sides. Screens move behind the fish section in sequential fashion as each camera scans the fish section.

A computer-controlled robot cutting system for making angled or beveled cuts along a preselected path in a workpiece having a generally planar cutting surface. A cutting knife, such as a high-intensity fluid jet, is pivotably mounted in a support frame having two pairs of arcuate guides disposed at right angles to each other for motor-driven rotation of the cutting knife about orthogonal axes. The centers of curvature of both guides lie on a critical plane containing a pivot point about which the cutting knife pivots. An opposing workpiece gantry with horizontal and vertical slides for motor-driven translation of the workpiece along two axes also includes means for holding the workpiece such that its surface to be cut faces the cutting knife and lies in the critical plane. The workpiece is thus translated to define the cutting path on the obverse surface, while the cutting knife is pivoted to define the entry angle of the cut along the cutting path. Four motion controllers under computer control coordinate the motors driving each axis of rotation or translation. Because the obverse cutting surface of the workpiece is maintained in the critical plane containing the pivot point, pivoting of the knife does not change its entry point in the cutting surface, thereby simplifying motion control algorithms. Furthermore, because the cutting knife is pivoted and the workpiece is translated, the relatively massive gearing and movable frame structures are distributed between the cutting knife section and the workpiece gantry, lowering the inertia and enabling the use of lighter-duty motors.

A fluid cutting system of improved configuration provides a high-velocity fluid that is rotated about a first axis (preferably a horizontal axis) on a moving trolley. The trolley is rotationally supported about a second axis (preferably vertical). The trolley travels upon a pair of arc-shaped tracks and is driven by a motor drive. The trolley has a pair of arc-shaped tracks that support the fluid jet nozzle. The fluid nozzle is thus rotatable about two axes, thereby emitting a high-pressure stream of fluid for adjustable cutting. A workpiece positioning frame has a fish section holder that can be elevated or moved laterally with respect to the cutting system.

A processing apparatus for use in the processing of transverse fish body sections includes a support frame and a video camera for providing a video image of a transverse fish body section to be processed when aimed at the fish body section along a preselected line of sight. A fish section support is provided for supporting the transverse fish section substantially over its area. The support can be invisible on the video photo image and preferably includes a plurality of spaced apart beams which are of a small dimensional width so that they do not appear on the video photo image that contains the fish body sections. A fluid jetting knife is movable with respect to the transverse fish body section for cutting the section with a pressurized fluid stream and positioned to traverse both the fish section and the support means during the cutting operation.
