Abstract
The powered endless belt (14) of a lower conveyor (12) transports workpieces (16) past a scanning station (18) and then past a slicing station (20), whereat the workpieces are sliced into desired thickness by a powered blade (23). An upper hold-down conveyor (24) includes a powered belt (26) that assists in holding the workpieces stationary and stable as workpieces travel past the slicing station (20). In this regard, the belt is of a compliant construction and is operated at a low enough tension to enable it to substantially conform to the contour of the upper surface of the workpiece, thereby to apply a substantially uniform load about the entire upper surface area of the workpiece.
Claims25
A compliant hold-down system for a food processing apparatus for slicing a deformable food product to a desired thickness and then separating the sliced sections of the deformable food product from each other, while gripping the top surface of a deformable food product to advance a deformable food product with a compliant hold-down conveyor configured to overlay and grip a deformable food product, the apparatus having a first conveyor for supporting, engaging, and transporting a deformable food product past the workstation, the compliant hold-down system comprising a moving belt structure draped over a deformable food product, wherein:
- the belt structure is of flexible material and operable under a low tension load such that the belt structure when draped over a deformable food product nominally conforming to the topography of the surface of a deformable food product facing the moving belt structure while gripping a deformable food product and to enable the distance separating the belt structure from the first conveyor to vary with the changes in topography of the deformable food product facing the moving belt structure;
- and
- the belt structure capable of applying a load on a deformable food product in the range of about 0.05 lb. per square inch to 0.2 lb. per square inch of deformable food product.
A food processing apparatus for cutting a deformable food product at a workstation to a desired thickness and then separating the sections of the cut food product from each other, the apparatus advancing a deformable food product to the workstation with a compliant hold-down conveyor to overlay and grip a deformable food product, the compliant hold-down conveyor operational in a slack condition to enable the hold-down conveyor to nominally conform to the contour of the upper surface of a deformable food product, the compliant hold-down conveyor overlaying and gripping the cut food product to slide the cut food product beyond the workstation along a separating surface for further processing, comprising:
- (a) a workstation for cutting a deformable food product to thickness;
- (b) a first powered support and transport surface for supporting, engaging and transporting a deformable food product to the workstation;
- and
- (c) a compliant hold-down conveyor cooperating with the support and transport surface to transport a deformable food product to the workstation, said compliant hold-down conveyor comprising a compliant conveyor belt spaced from the support and transport surface and positionable to overlay a deformable food product to grip and apply a load on a deformable food product as a deformable food product is being transported to the workstation, the compliant hold-down conveyor belt constructed of flexible material and operable under a low tension load resulting substantially only from the gravitational mass of the hold-down conveyor belt to nominally conform to the contours of a deformable food product top surface facing the compliant hold-down conveyor belt and to permit the distance separating the compliant hold-down conveyor belt from the support and transport surface to vary with the change in contour of the top surface of the food product, while still gripping a deformable food product during transport of the food product;
- (d) a separator plate positioned above the first support and transport surface extending beyond the cutting workstation;
- and
- (e) the compliant hold-down conveyor gripping the cut deformable food product to slide the cut deformable food product on the separator plate away from the workstation.
A slicing apparatus for slicing raw meat product to a desired thickness and separating the sliced sections of raw meat product from each other, while gripping the top surface of a raw meat product to advance a raw meat product for slicing with a compliant hold-down conveyor to overlay and grip a raw meat product, comprising:
- (a) a slicer device for slicing a raw meat product;
- (b) a first conveyor for supporting, engaging, and conveying a raw meat product as a raw meat product is being sliced by the slicer device;
- and
- (c) a compliant hold-down conveyor comprising a compliant conveyor belt spaced from the first conveyor and cooperating with the first conveyor to apply a load on a raw meat product as a raw meat product is being transported past the slicer device, the compliant hold-down conveyor belt constructed with compliant material and operable under a low tension load on said compliant conveyor belt to nominally conform to the contour of the surface of the raw meat product facing the compliant hold-down conveyor belt, said conformance resulting from a downward force generated substantially only by the gravitational mass of the hold-down conveyor belt, while gripping the raw meat product to advance the raw meat product, and to permit the distance separating the compliant hold-down conveyor belt from the first conveyor to vary with the change in the contour of the surface of the raw meat product facing the compliant hold-down conveyor belt;
- (d) a separator tray positioned above the first conveyor to extend beyond the slicer device;
- and
- (e) the compliant hold-down conveyor gripping the sliced raw meat product to slide the sliced deformable work product on and along the separator tray away from the slicer device.
