A conveyor and a method for rotating and registering an article against a rail. The conveyor includes an angled-roller conveyor belt whose article-supporting rollers are arranged to rotate about axes directing conveyed articles toward a side rail. An obstruction is selectively activated to move into a position just above a top article-conveying surface of the belt. In that position, the obstruction intercepts conveyed articles. The obstruction forms a pivot about which the articles rotate as the belt advances and the angled rollers rotate. An electric eye or other sensor sensitive to oversized or misoriented articles controls the positioning of the obstruction to rotate misoriented articles 90&#xb0; or to let correctly oriented articles pass without contact and reorientation.

Angled-roller belt conveyor

A conveyor system including a pair of roller-top belts arranged side by side, each individually controllable to cause articles conveyed atop both to rotate into preferred orientations. The roller-top belts include rollers that rotate about axes oblique to the direction of belt travel. The rollers on each belt direct conveyed articles toward the other belt as the belts advance in the direction of belt travel and the rollers contact an underlying bearing surface in rolling contact. The rotation of the rollers exerts a force on articles conveyed atop the rollers. The force has a component directed toward the other belt and another component directed downstream. A sensor array senses the footprint of an article at an upstream location and sends signals to a controller that determines the size and orientation of the article to selectively stop one or the other roller-top belt if necessary to rotate the article to change its orientation.

Angled-roller article-rotating belt conveyor

A method and apparatus for processing fish prior to canning to increase yield. The method includes the steps of first preparing the fish body for further processing by: removing (,) the tail, pectoral, and thoracic fins from a frozen fish body, removing the scales (,) from the frozen fish body, dipping the fish body in a hot bath (,) to thaw the skin and subdermal layer of the fish, dipping the fish body in a cooling bath (,) to stop fixer thawing, skinning (,) the fish body, and finally removing the dorsal and ventral fins (,). The method also includes the steps of preparing separated loin portions of the fish body for canning by: immersing frozen loin pieces in a heated broth bath (,) to coat the pieces with broth and then cooking the pieces in a hot water bath (,) until the internal temperature of the pieces reaches a preferred temperature. A preferred scaling apparatus includes a scaler assembly (,), a holder (,) for the fish body, and means for moving the scaler assembly close to the holder. Circumferentially spaced fingers (,) pivotally attached to the rotating scaler assembly contact the outer surface of the fish body and chip scales away.

Method and apparatus for processing fish

Apparatus and method for automatically subdividing carcasses, especially fish bodies, into individual slab sections. A preferred embodiment of the cutting apparatus includes a feed mechanism and a cutting mechanism coordinated by computer. The feed mechanism comprises a motor-driven carriage that rides upon rails. Between the rails is a feed track formed by parallel guides having angled facing surfaces defining a channel to accommodate a fish body aligned along the channel. A retainer on the carriage secures the head end of the fish body so that it can be advanced along the channel by the carriage without a change in orientation. The cutting mechanism includes a reciprocating blade that is advanced in a direction to define a cutting plane intersecting the path the fish body takes as it is transported by the carriage beyond the end of the feed track. Holding blocks at the end of the feed track clamp the fish body securely in position for cutting. The blade slices through the stationary fish body to sever a slab section from one end with minimal kerf loss and shredding. A slab holder is inserted in the peripheral girth of the severed slab section before both are conveyed off. The process is repeated until the fish body is subdivided into a predetermined number of slab sections with each of the severed slab sections held by its own holder in the same relative location so that the general orientation of the severed slab can be determined in downstream processing by reference to the holder.

Slabbing apparatus and method

Apparatus and method for subdividing a fish body into a loin-containing portion and a viscera-containing portion. The apparatus includes a carrier, a cutting assembly, and a runway connecting the two. The cutting assembly and a fish body supported on the carrier are advanced relative to each other along the runway. Blades at the cutting assembly flank the runway and form a pair of angled cuts intersecting to form a V-cut that opens toward the ventral side of the fish body. The planes of the blades are separated by an angle of between 80.degree. and 160.degree., depending on fish species and size, to minimize the amount of loin meat separated with the viscera. Means are provided for setting the tilt of the longitudinal axis of the fish body relative to the path of the vertex of the V-cut so that the path extends between the backbone of the fish and its visceral cavity substantially from the vent to a point on the outside surface of the fish body in the vicinity of the eyes. In this way, a wedge-shaped belly section containing the viscera and belly bones is cut from the remaining loin-containing sections of the fish body. The two sections are thereby made available for downstream processing at separate stations.

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.

Robot cutting system

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.

Fluid jet cutting knife apparatus

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.

Imaging system for use in processing transversely cut fish body sections

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.
