Abstract
Abstract The meat slice stacking apparatus includes a carrier on which meat slices are piled in discrete stacks and means for dropping successive meat slices onto the stacks; said dropping means including a trap which is alternately movable between a closed position in which it takes delivery of a meat slice from a transport and an open position in which it drops the meat slice onto the stack; the movements of the trap being governed by a sensor which senses meat slices on the transport as it carried them past a sensing station located to sense successive meat slices following the leading meat slices on the transport whereby to procure closing of the trap before said leading meat slices are respectively delivered to and seated on the trap.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
194 words
In meat slice stacking apparatus: a transport for conveying successive meat slices from a source to a delivery station; means at said source for loading successive meat slices on said transport in generally regularly spaced sequence; a trap at said delivery station alternately movable between a closed position for taking delivery of successive meat slices from said transport and an open position for releasing them sequentially to a stacking facility, said transport being operable at speeds and said meat slices being spaced on said transport to permit re-closing the trap following release of a meat slice as aforesaid before a succeeding meat slice is delivered thereto by said transport; a sensor located for sensing a meat slice being conveyed by said transport past a sensing location after a preceding meat slice has come to rest on said trap; mechanism operable by said sensor upon sensing a said meat slice to procure and maintain opening of the trap for the release of the said preceding meat slice to the stacking facility; and means for procuring re-closing of said trap after the release of said preceding meat slice and before delivery of another meat slice thereto.
Claim 2
Dependent Claim
194 words
In meat slice stacking apparatus: a transport for conveying successive meat slices from a source to a delivery station; means at said source for loading successive meat slices on said transport in generally regularly spaced sequence; a trap at said delivery station alternately movable between a closed position for taking delivery of successive meat slices from said transport and an open position for releasing them sequentially to a stacking facility, said transport being operable at speeds and said meat slices being spaced on said transport to permit re-closing the trap following release of a meat slice as aforesaid before a succeeding meat slice is delivered thereto by said transport; a sensor located for sensing a meat slice being conveyed by said transport past a sensing location after a preceding meat slice has come to rest on said trap; mechanism operable by said sensor upon sensing a said meat slice to procure and maintain opening of the trap for the release of the said preceding meat slice to the stacking facility; and means for procuring re-closing of said trap after the release of said preceding meat slice and before delivery of another meat slice thereto.
Claim 3
Dependent Claim
28 words
Apparatus according to claim 1 including a timer for limiting the time during which said mechanism is operable by said sensor as aforesaid while sensing a meat slice.
Claim 4
Dependent Claim
26 words
Apparatus according to claim 1 in which the sensor is located to sense at least the second meat slice in line for delivery to the trap.
Claim 5
Dependent Claim
29 words
Apparatus according to claim 3 in which the sensing location is variable in the direction of the movement of the meat slices from the source to the delivery station.
Claim 6
Dependent Claim
36 words
Apparatus according to claim 4 in which the sensor includes an electronic transducer which emits a signal when a meat slice is sensed initiating operation of the mechanism to procure and maintain opening of said trap.
Claim 7
Dependent Claim
88 words
Apparatus according to claim 1 including a carrier forming part of said stacking facility to which the meat slices are released by the trap, said carrier having a plurality of stacking sites and being advanceable to dispose a fresh stacking site below the trap when the next preceding stacking site has received its quota of meat slices, partitions separating said stacking sites forming said stacking sites into walled compartments, each of said partitions having a camming formation on its upper portion for camming meat slices into a compartment.
Claim 8
Dependent Claim
19 words
Apparatus according to claim 6 wherein the carrier is an endless device on which the partitions are perpendicularly disposed.
Claim 9
Dependent Claim
46 words
Apparatus according to claim 7 in which each said partition is comprised of two plates disposable in close collateral adjacency and the upper portion of each plate is shaped to co-operate with the upper portion of the collateral plate to provide the camming formation as aforesaid.
Claim 10
Dependent Claim
12 words
Apparatus according to claim 8 wherein said camming formation is a bevel.
Claim 11
Dependent Claim
16 words
Apparatus according to claim 8 including webs providing said stacking sites; adjacent webs being articulatably interconnected.
Claim 12
Dependent Claim
14 words
Apparatus according to claim 10 in which said carrier is comprised of said webs.
Claim 13
Dependent Claim
101 words
Apparatus according to claim 1 in which the sensor is located to sense at least the second meat slice in line for delivery to the trap and in which the sensing location is variable in the direction of movement of the meat slices from the source to the delivery station and includes an electronic transducer which emits a signal when a meat slice is sensed, initiating operation of the mechanism to procure and maintain opening of said trap and a timer for limiting the time during which said mechanism is operable by said sensor as aforesaid while sensing a meat slice.
Claim 14
Dependent Claim
126 words
Apparatus according to claim 12 including an endless carrier forming part of said stacking facility to which the meat slices are released by the trap; said carrier comprising webs providing stacking sites, adjacent webs being articulatably interconnected, and being advanceable to dispose a fresh stacking site below the trap when the next preceding stacking site has received its quota of meat slices, partitions, perpendicularly disposed on said carrier separating said stacking sites and forming said stacking sites into walled compartments, each said partition being comprised of two partition plates disposed in close collateral adjacency, the upper portion of each partition plate shaped to co-operate with the upper portion of the collateral partition plate to provide the camming formation as aforesaid, said camming formation being a bevel.
