Abstract
A capsule rectification and transport device is disclosed. Means are provided for removing occasional improperly positioned capsules from the transported array. The capsules are carried in spaced apart pockets. When a capsule is undesirably mis-oriented with the cap portion thereof facing the wrong side of the predetermined path, a rotatable pick-off wheel grasps the cap portion, removes the capsule and drops it into a hopper.
Claims7
Method for removing improperly rectified telescoping capsules from a traveling capsule array, wherein said capsules have body portions and cap portions of enlarged diameter relative to said body portions, slideably telescoping over said body portions, said method comprising:
- (a) loading a multiplicity of said capsules into a hopper;
- (b) transferring the capsules from the hopper to a rotatable transport cylinder having a plurality of capsule carrying cavities at the surface thereof;
- said capsules being disposed in random fashion in said cavities, one capsule per cavity, arrangement of said cavities on said transport cylinder defining capsule spacing while within said array;
- (c) rectifying substantially all of said capsules in said cavities on said transport cylinder while occasionally appearing non-rectified capsules continue traveling on said transport cylinder;
- (d) applying gripping means about all of said capsules, but grasping only said occasionally appearing non-rectified capsules, as said capsules, being substantially rectified, travel in said array;
- and
- (e) removing said non-rectified capsules from said traveling array by exerting force on said non-rectified capsules substantially normal to the direction of travel of said array with said gripping means while removing said gripping means from about said rectified capsules thereby leaving said rectified capsules undisturbed in their previously rectified state while said array is moving.
In a capsule rectification and transport device, wherein said capsules are caused to travel from an upstream location to a downstream location and wherein said capsules comprise body portions and enlarged cap portions, the combination comprising, hopper means into which a multiplicity of capsules are to be loaded, an endless conveyor, transport means for receiving said capsules from said hopper and for transporting them in a downstream direction along a predetermined path to said endless conveyor, rectification means disposed adjacent to said transport means for rectifying substantially all of said capsules into dispositions in which said cap portions of said rectified capsules lie along one side of a predetermined path and in which said body portions of said rectified capsules lie on the opposite side of said predetermined path, whereby occasionally appearing non-rectified capsules continue to travel on said transport means, and non-rectified capsule removal means located downstream from said rectification means for removing said occasionally appearing non-rectified capsules from said predetermined path, said removal means being positioned adjacent said predetermined path for contacting said non-rectified capsules as they are carried along said predetermined path, and said removal means comprising engagement means physically structured for grasping the non-rectified capsules and being shaped in such a manner so as to grasp only non-rectified capsules while not being capable of grasping rectified capsules, said removal means having capacity for removing said non-rectified capsules from said path, and means provided for removing said non-rectified capsules from said removal means.
