An improved method and apparatus for plucking fiber tufts from a fiber bale held by a supporting frame which is reciprocally displaced along a carrying passage over a plucking roller. A pair of conveyer means are disposed with an intervened space therebetween and the plucking roller is disposed in the abovementioned intervened space. An auxiliary conveyer means is disposed at a position adjacently outside one of the conveyer means. These three conveyer means are arranged in an alignment. The supporting frame is capable of being reciprocally displaced by the conveyer means between displacing terminals on said conveyer means and is capable of being displaced to a waiting position on one of the conveyer means which is outside of the displacing terminal on that conveyer means and at a side of the auxiliary conveyer means. A door means of the supporting frame is opened during the displacing motion of the supporting frame to the waiting position, and then a fresh fiber bale reserved on the auxiliary conveyer means is supplied into the supporting frame, thereafter the supporting frame is displaced to the normal operational position thereof. A loading plate is mounted on the supporting frame so as to uniformly press the fiber bale during the bale plucking operation. All of the above-mentioned operations are carried out automatically.
In a method for plucking fiber tufts from a fiber bale, by a bale plucking machine comprising a pair of conveyer means and a plucking roller disposed between said conveyer means, during reciprocal displacement of said fiber bale over said plucking roller, an improvement comprising:
In a bale plucking machine comprising a pair of conveyer means disposed at an identical level with an intervened space therebetween, and a plucking roller disposed in said intervened space, means for driving said conveyer means to and fro so that a fiber bale is reciprocally displaced between two terminals of the reciprocal displacement thereof, an improvement comprising an auxiliary conveyer means disposed at a position adjacently outside an end of one of said conveyer means, a supporting frame for holding said fiber bale disposed on said conveyer means in displaceable condition along said conveyer means, means forming part of said means for driving said conveyer means to and fro, for changing the driving direction of said conveyer means when said supporting frame arrives at said two terminals of said reciprocal displacement of said fiber bale, signalling means for detecting exhaustion of said fiber bale held in said supporting frame, said supporting frame being provided with a door means, means responsive to said means for detecting exhaustion of said fiber bale for actuating said means for driving said conveyor means to displace said supporting frame toward a waiting position outside a region of said reciprocal displacement of said fiber bale on one of said conveyer means without actuating said driving - direction changing means according to a signal issued from said means for detecting exhaustion of a fiber bale, means for opening said door means of said supporting frame while said supporting frame is being displaced to said waiting position, signalling means for detecting arrival of said supporting frame at said waiting position, means responsive to a signal from said means for detecting arrival of said supporting frame at said waiting position, for temporarily driving said auxiliary conveyer means when said supporting frame is positioned at said waiting position for receiving a fresh fiber bale, said means for temporarily driving said auxiliary conveyer means being adapted to transfer a fresh fiber bale reserved on said auxiliary conveyer means into said supporting frame positioned at said waiting position, means for actuating said means for driving said conveyer means to and fro when said supporting frame receives a fresh fiber bale from said auxiliary conveyer means, for displacing said supporting frame toward said plucking roller.
