摘要:
A versatile high speed slicing machine moves first and second food loaves along parallel loaf paths into a slicing station where both loaves are sliced by a cyclically driven knife blade. There are independent loaf feed drives so that slices cut from one loaf may be thicker than slices from the other. The conveyor/transfer system onto which food loaves are deposited as cut includes a receiver located below the slicing station; a lift mechanism moves the receiver down during slicing so that slices always fall about the same distance after being cut. The receiver includes a horizontal conveyor that periodically discharges groups of food loaf slices onto a deceleration conveyor, from which the groups are fed onto a multi-belt scale conveyor. The scale conveyor is aligned with two receiver grids, each grid including plural grid elements interleaved one-for-one with the scale conveyor belts. In each machine cycle a group of food loaf slices is deposited on a grid and weighed. Two slice groups are usually weighed individually and simultaneously. The group weights control two classifier transfer conveyors.

摘要:
A high speed slicing machine supports first and second food loaves for movement along parallel loaf paths into a slicing station where both loaves are sliced by one cyclically driven knife blade; the slices are stacked or shingled in groups on a receiving conveyor located below the slicing station. Independent loaf feed drives are provided; slices cut from one loaf may be thicker than slices from the other. The machine combines manual and automated mechanisms to load food loaves onto the food paths. These mechanisms share a central barrier that is used only during loading; at other times the barrier is clear of the loaf paths. The automated loaf loading mechanism has a sweep to push one or more loaves onto a support defining the loaf paths. There are two grippers, one on each loaf path; each grips the end of a loaf remote from the slicing station. For each gripper, a loaf feed drive impels the gripper (and loaf) toward the slicing station and then moves the gripper back to a home position, releasing an unsliced loaf butt on the way through a door opening in the loaf support. Each loaf feed drive includes two "short" conveyors driven at the same speed as the gripper. The loaf support is pivotally movable to a cleanup position; in its normal support position the loaf support masks the grippers, the loaf feed drive, the barrier, and the sweeps, but in cleanup position it exposes them all.

A conveyor system is set forth. The conveyor system includes first and second strip conveyors. The first and second strip conveyors comprise a common input end that is common to both of the first and second strip conveyors. A lateral drive is disposed to drive the common input end in a lateral direction. A first output portion terminates the output of the first strip conveyor and a second output portion terminates the output of the second strip conveyor. A lateral adjustment assembly is used for laterally adjusting the first and second output portions independent of one another. The first and second strip conveyors are particularly useful in a conveyor system for accepting one or more streams of product input and converting the one or more streams to a format that is suitable for automatic loading to a subsequent machine.

A conveyor system for accepting one or more streams of product input and converting the one or more streams to a format that is suitable for automatic loading to a subsequent machine is disclosed. The conveyor system comprises an input level shifting conveyor disposed to receive the one or more product input streams. The level shifting conveyor is movable between a first upper level position and second lower level position. An upper level strip conveyor is disposed to receive product from the input level shifting conveyor when the input level shifting conveyor is moved to the first upper level position. The upper level strip conveyor includes an output end that is in a fixed position to direct product received by the upper level strip conveyor to a first lateral alignment position of the format. A lower level strip conveyor is disposed to receive product from the level shifting conveyor when the level shifting conveyor is moved to the second lower level position. The lower level strip conveyor includes an output end that is in a fixed position to direct product received by the lower level strip conveyor to a second lateral alignment position of the format. The second lateral alignment position is different from the first lateral alignment position. An output level shifting conveyor is also used. The output level shifting conveyor is movable between a first upper level position at which it is disposed to receive product from the upper level strip conveyor and a second lower level at which it is disposed to receive product from the lower level strip conveyor.
摘要:
A high volume food load slicing machine comprising a pair of loaf feed belt conveyors that continuously advance a food loaf along a downwardly inclined path through a collar into a slicing station at which a rotating and orbiting knife slices the load includes a variable speed knife rotation drive independent of the main drive that orbits the knife and drives the loaf conveyors. A hydrostatic speed variator in the drive connection for the conveyors, with speed corrections made by a stepper motor, affords precision control of slice thickness. A split collar and associated sensor afford continuous sensing of the loaf cross section to provide effective slice thickness correction; the collar is of molded machinable resin so that the knife can cut a working surface on the collar to a precise contour. The collar includes vacuum means to hold the butt end of a loaf for slicing.
摘要:
This invention is a stacker for a food loaf slicing machine of the kind in which a food loaf is advanced into a slicing station where slices of generally uniform thickness are cyclically sliced from the end of the loaf. The stacker includes first and second stack supports which are positionable to receive slices as they are cut off the loaf. When one stack support has received a complete stack that support is moved to a displaced discharge position and the other stack support immediately moves into an initial slice receiving position immediately adjacent the slicing station, where it can receive a first food loaf slice as cut with essentially no free fall. The stack support is then displaced downwardly approximately one additional slice thickness for each successive slice received, so that each food loaf slice is added to the stack with no free fall. The stack supports transfer the stack to the discharge position without any free fall; continuous support is provided throughout all stack formation and transfer operations.

A cryogenic food product freezing tunnel including an elongated housing having a food product entrance at one end, a food product exit at the other end, a food product conveyor extending through the tunnel, a cryogen input near the food product exit, an exhaust stack near the food product entrance with an exhaust blower atop the stack, a plurality of cryogen circulating fans spaced along the length of the tunnel, a variable speed directional blower intermediate the cryogen input and the food product entrance, a cryogen input control, and a temperature sensor positioned between the directional blower and the cryogen input. The improved cryogen gas flow control system of the invention comprises a variable speed drive for the exhaust blower and a blower speed control, connected to the temperature sensor, that varies the speeds of both the directional blower and the exhaust blower as functions of the temperature sensed by the temperature sensor; the blower speed control is also a part of the cryogen input control, and varies the cryogen input, again as a function of the sensed temperature.
摘要:
A mold station of a food patty molding machine in which a food pump pumps a moldable food product through a fill passage into mold cavities in a cyclically reciprocating mold plate, with a multi-orifice plate interposed in the fill passage and a stripper plate, slidably mounted immediately adjacent the orifice plate, having a multiplicity of fill openings aligned one-for-one with the fill orifices; a stripper plate drive, synchronized with the mold plate drive, slides the stripper plate a short distance to a seal-off location once in each mold plate cycle. The spacings between fill openings in the stripper plate are made large enough to close all of the fill orifices when the stripper plate is moved to its seal-off location; the stripper plate drive shifts the stripper plate to its seal-off location before movement of the mold plate toward its discharge position can create an open outlet path from the food pump through the mold cavities to outside of the mold station.
摘要:
A machine for molding hamburger patties and other similar food patties, of the kind incorporating a vacuum-intake plunger-type food pump that pumps food product from a supply hopper into mold cavities in a reciprocating mold plate, is equipped with a hydraulic drive system that drives both the food pump and a pair of feed screws that impel the food product toward the pump intake. The feed screws axes are approximately parallel to the direction of travel of the plunger and the outlet end of the feed screws is enclosed to preclude reverse movement of food product from the food pump into the supply hopper at the beginning of the pumping stroke; rotation of the feed screws is timed to coincide with the intake stroke of the pump in an arrangement that can be made to compensate for variations in pumped volume of the food product. A single hydraulic pump provides both a low-pressure hydraulic supply for plunger advance and a high-pressure hydraulic supply for plunger retraction and feed screw rotation. One electric motor powers both the hydraulic pump and a mechanical drive for the mold plate.
