Abstract

A bale bagging apparatus for placing a bag having an open end and a closed end over an elongated bale transported transversely along a conveyor, the apparatus having a stop reciprocable toward and from the bale to retain the bale at a bagging station along the conveyor; an open ended sleeve adapted to receive the bag externally and to telescope over the bale, the sleeve reciprocating in a path which is normal to the conveyor and extends across the station from a bag receiving position to a stripped position; and elements for stopping movement of the bale along the conveyor when the bale is aligned with the sleeve, so that a stroke of the sleeve from the receiving position into the stripped position strips the bag from the sleeve over the bale.

Dependent claims

A bale bagging apparatus for covering an elongated bale having a central longitudinal axis with a bag having an open end and an opposite closed end comprising:

A. a feed conveyor for transporting such a bale rested thereon along a first horizontal, generally linear path in a predetermined direction with the bale disposed with said axis extended generally horizontally and transversely of said direction of travel, said conveyor having a predetermined discharge end;
B. a discharge conveyor for transporting such a bale rested thereon along the path with the bale disposed with said axis extended generally horizontally and transversely of said direction of travel, the discharge conveyor having a receiving end disposed in spaced end-to-end relationship along the path with said discharge end, the distance between said ends being substantially less than the dimension of the bale along the path;
C. a track disposed downwardly of the conveyors and extended along a predetermined second horizontal, generally linear path substantially normal to the first path and disposed therealong so that said ends of the conveyors are disposed centrally in the second path;
D. a carriage mounted on the track for reciprocal movement along the second path from side to side of the conveyors and having an upwardly extended pillar disposed to pass between said ends of the conveyors during the reciprocal movement;
E. power means for simultaneously driving the conveyors to transport a bale so disposed thereon along the first path in a direction from the feed conveyor toward the discharge conveyor;
F. means powering a stroke of the carriage along the second path from a receiving position at one side of the conveyors to a stripped position at the opposite side of the conveyors;
G. a sleeve upwardly mounted on the pillars for movement with the carriage along the second path above the conveyors, the sleeve being elongated along a central axis thereof extended horizontally along the second path in a vertical plane extending between said ends of the conveyors, having a pair of open, longitudinally opposite ends, conforming centrally to the transverse cross section of the bale, and being adapted to receive such a bag in a disposition in which the bag is fitted outwardly of and along the sleeve with the open end thereof disposed toward the conveyors when the carriage is in the receiving position;
H. a stop disposed adjacent to said opposite side of the conveyors and dimensioned to pass centrally through the sleeve, the stop having a face normal to the central axis of the sleeve and a rod extended parallel to said axis from the face in a direction away from the conveyors to an end of the rod disposed beyond the stripped position;
I. means connected to the rod mounting the stop for reciprocal movement along the second path between a retaining position in which the face is adjacent to said opposite side of the conveyor and a releasing position in which the face is spaced substantially from the retaining position in a direction from the receiving position of the carriage toward the stripped position thereof;
J. control means for stopping the conveyors when the longitudinal axis of the bale is generally aligned in a direction along the second path with the central axis of the sleeve;
K. means for powering a stroke of the stop toward the retaining position thereof with said axes so aligned when the conveyors are stopped by the control means so that the face engages the bale retaining the bale on the conveyors against movement therefrom in a direction along the second path from the receiving position toward the stripped position;
L. means for powering a stroke of the carriage from the receiving position into the stripped position when a bag is so disposed on the sleeve and the face of the stop is so engaged with the bale, the sleeve passing over the bale so that the closed end of the bag engages the bale during said stroke and the bag is stripped from the sleeve into bagged relation with the bale as said stroke continues;
M. means for powering a stroke of the stop from the retaining position thereof into the releasing position thereof when said stroke of the carriage is substantially complete so that the face of the stop is spaced from the bale;
N. means for starting the conveyor driving means when said stroke of the stop into the released position thereof is substantially complete so that the bagged bale is transported along the first path in said predetermined direction from the second path;
and
O. means for powering a stroke of the carriage from the stripped position into the receiving position when the bagged bale has been so transported along the first path out of the second path.
