  • Patent number: 6882434
    Abstract: A system, suitable for high-speed operation, by which raw product (45), such as a slab of meat, can be accurately processed, such as by slicing into segments of desired weight, comprises a product profiling apparatus (15). The product profiling apparats (15) meassures the profile of the physical process. The product profiling apparatus (15) includes line lasers (75, 85) for directing a line of light across the upper and lower surfaces of the product (45) and visual image cameras (80, 90) directed toward the profile surface to capture, at fixed increments, the product profile. The product may also be weighed and the product density determined from the overall profile measurements. A controller (150) receives this data, and instructs the physical process accordingly.

  • Patent number: 6854582
    Abstract: An improved stopping mechanism is provided for a conveyor that accepts one or more streams of product input and converts the one or more streams to a format that is suitable for automatic loading to a subsequent machine, wherein a stack of slices must be temporarily stopped on the conveyor while moving. The stopping mechanism includes a lower stop having a lower stack-engaging portion and a lift portion, the lift portion selectively actuatable to elevate the lower stack-engaging portion to engage a bottom surface of the stack and to lift the stack above the conveying surface. The stopping mechanism further includes an upper stop having an upper stack-engaging portion and a lowering portion, the lowering portion selectively actuatable to lower the upper stack-engaging portion to engage an upper surface of the stack.

  • Patent number: 6769337
    Abstract: An improved orifice plate assembly for a loaf slicing machine, the orifice plate assembly located adjacent to a moving slicing blade includes a frame defining an opening and a first orifice-defining member and a second orifice-defining member slidably mounted together slidably on the frame. The first orifice-defining member and the second orifice-defining member, together define an orifice. An adjustment mechanism is operatively connected to the frame and to each of the first and second orifice-defining members, the adjustment mechanism when adjusted changes the orifice dimension between the first and second orifice-defining members without substantially changing a centerline location of the orifice. The adjustment mechanism includes a stud fixed to the first orifice-defining member, and two links pivotally mounted to the frame and engaged to two rods fixed to the second orifice-defining member.

  • Patent number: 6763748
    Abstract: A slicing and conveying system forms a three or more flavor-combined draft. A first slicing machine slices a succession of first and third slices in first and third shingled drafts. A second slicing machine slices a succession of second slices in second shingled drafts. A pass-through conveyor transfers the first draft to an output conveyor of the second slicing machine, wherein the second draft is added to the first draft to form a first combined draft. An overlap conveyor receives the first combined draft and merges the first combined draft with the third draft on the overlap conveyor to form an elongated combined draft. Optical sensors determine lengths of the first draft, the second draft, the third draft, and/or the elongated combined draft.

  • Publication number: 20040055439
    Abstract: A loaf reload mechanism for a slicing machine that includes a loaf-loading position wherein during a loading operation a loaf is placed in the loaf-loading position. During loading a gripper moves from a home position clear of a loaf in the loaf-loading position to an engagement position wherein the gripper engages a trailing end of the loaf. During a slicing operation, the gripper moves with the loaf along a longitudinal path into a slicing plane of a moving slicing blade until the loaf is effectively entirely sliced by the blade. The gripper is then retracted in a reverse direction to the home position. The loaf reload mechanism includes a loaf-staging position over the loaf-loading position, the loaf-staging position having a lowering mechanism to position a loaf from the loaf-staging position to the loaf-loading position.

  • Publication number: 20040031363
    Abstract: The invention provides a slicing and conveying system that includes a slicing blade that cuts slices from a loaf, and an output conveyor located below the slicing blade for receiving the slices in a draft. A control system automatically adjusts a lateral movement of the output conveyor to form a laterally shingled draft of a consistent width in response to a sensed lateral dimension of the loaf being sliced. The control system includes a displacement sensor carried by a laterally adjustable guide assembly adjacent to the slicing blade. The displacement sensor is signal-connected to a control. The control is signal-connected to the output conveyor to control the lateral movement of the output conveyor according to the lateral dimension of the loaf sensed by the displacement sensor. As an additional aspect, the slices can be shingled in the longitudinal direction to form a two dimensional footprint.

  • Patent number: 6635830
    Abstract: A control for a weigh scale associated with a continuously moving conveyor which is capable of mathematically positioning the sample period on each product weight waveform. The control first triggers on a predetermined sensed weight. The control determines a first inflection point on the weight waveform defined as the “maximum positive slope.” Once the maximum positive slope is found, the control begins recording weight samples at a sampling rate. The control checks the weight waveform of sampled weights for a slope which is a first pre-selected percentage of the maximum slope but negative in slope value. This point is determined as the “weight-off-scale” point. When the weight-off-scale point is reached, then the control looks backward through the recorded data of weight samples to find another point which has a slope which is a second preselected negative percentage of the maximum positive slope. This point is defined as the “end sample position.

  • Patent number: 6484615
    Abstract: A slicing machine including a slicing blade for slicing at least first and second product loaves disposed in a side-by-side arrangement using a single rotation of the slicing blade is set forth. A single rotation of the slicing edge about the center of rotation results in a penetration gradient into each of the first and second product loaves that diminishes in magnitude over the single rotation. To this end, the slicing edge may have a profile defined a plurality of constant radius sections. Each constant radius section has a section center defining the center of the constant radius for that constant radius section. Further, each constant radius section has a section center differing from the section center of an adjacent constant radius section. Such a blade and its associated slicing station provide great control of slices from the loaves as they proceed from the loaf to a receiving conveyor of the slicing station.

  • Patent number: 5974925
    Abstract: A high speed slicing machine feeds two or more food loaves continuously along parallel loaf paths through an orifice member into a slicing station for slicing by one cyclically driven knife blade; the slices are stacked or shingled in groups on a receiving conveyor below the slicing station. There are two independent loaf feed drives; slices from one loaf may be thicker than slices from the others. Each loaf feed drive advances at least one loaf into the slicing station, partly by gravity and partly by a positive loaf feed drive. Each positive loaf feed drive comprises a pair of angularly converging "short" conveyors; adjustments and bias are provided for each set of "short" conveyors. In the slicing station, an arcuate blade is rotated along a closed cutting path that intersects the ends of food loaves fed into the slicing station. A conveyor system discharges groups of food loaf slices after they are weighed.
