Machine for a continuous commercially packing of slaughtered fowl

Claim 2

An improved machine for continuous commercial packing of slaughtered fowl into bags of the type having a packing funnel, a piston which pushes the fowl through the packing funnel and a bag supply which is provided at the discharge opening of the packing funnel, the improvement comprising: a centering tool disposed in front of the entrance opening of the packing funnel, said centering tool including means for enclosing the legs of the slaughtered fowl and pushing the legs into the path of said piston, said means being movable in timed relationship with respect to said piston; drive means for reciprocally moving said means for enclosing and pushing between an operating and non-operating position; and a bag clamping element coupled to and actuated by said drive means for clamping a bag from said bag supply onto the rim of said discharge opening of said packing funnel.

Claim 3

The machine according to claim 1, wherein said bag supply includes a horizontally-reciprocal carriage for supporting a stack of bags which is moveable toward and away from the discharge opening of said packing funnel along a path in parallel alignment with respect to said path of said piston which carriage is moveable in timed relationship with respect to said piston, and a compressed air operated nozzle mounted on said carriage which is disposed to blow air into the uppermost bag of said stack.

Claim 4

The machine according to claim 1, wherein the front face of said piston is provided with a recess.

Claim 5

The machine according to claim 1, wherein said means for enclosing and pushing includes a vertically-disposed fixed guide, mounted in front of said entrance opening of said packing funnel through which said piston is moveable and a pair of shank members moveably supported on said guide which are disposed to straddle the fowl disposed therebetween.

Claim 6

The machine according to claim 4, wherein said guide comprises an upwardly opening, U-shaped yoke, on each of the arms of which the outer end of one of said shank members is slidably supported.

Claim 7

The machine according to claim 5, wherein said centering tool, in cooperation with said shank members thereof, define a generally downwardly-opening semicircular clamping surface which compliment said upwardly opening U-shaped yoke.

Claim 8

The machine according to claim 4, additionally including a pretensioned spring coupled to said shank members for maintaining said shank members in a straddling position.

Claim 9

The machine according to claim 4, wherein said drive means comprises a cylinder having a piston rod which is vertically moveable between a retracted and an extended position, both of which lie in the same plane as said yoke.

Claim 10

The machine according to claim 8, additionally including a support mounted on said piston rod, and a spring-loaded clamping yoke pivotably mounted on said support, one end of which supports said bag clamping element, said clamping yoke being pivotably moveable between a clamping position, in which said end of said clamping yoke and, in turn, said bag clamping element is urged against said rim of said discharge opening of said packing funnel to clamp a bag therebetween and, a non-clamping position, in which said bag clamping element and said end thereof is moved away from contact with said rim of said discharge opening to permit release of said bag, said clamping position being effected by movement of said piston rod from said retracted to said extended position thereof and said non-clamping position being effected by movement of said piston rod from said extended to said retracted position thereof.
