Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A plant for sorting washing in laundries, comprising a closed horizontal conveyor for transporting ironed washing, said conveyor having one hauling chain made as interhinged carriages; a timer; cams mounted on said carriages; comblike cantilEver hangers disposed on said carriages, said hangers mounted capably of turning when addressee-selecting arrows disposed on the conveyor are actuated by a signal from said timer; a receiving bunker fashioned as a row of series-arranged compartments; movable shelves positioned in said bunker and intended for stacking washing thereon; stationary combs likewise positioned in said bunker, said combs interacting with said comblike hangers during the turn thereof; sensors of the level of washing disposed in the bunker and generating signals for lowering the movable shelves of the bunker.
Claim 2
Dependent Claim
122 words
A plant for sorting washing in laundries, comprising a closed horizontal conveyor for transporting ironed washing, said conveyor having one hauling chain made as interhinged carriages; a timer; cams mounted on said carriages; comblike cantilEver hangers disposed on said carriages, said hangers mounted capably of turning when addressee-selecting arrows disposed on the conveyor are actuated by a signal from said timer; a receiving bunker fashioned as a row of series-arranged compartments; movable shelves positioned in said bunker and intended for stacking washing thereon; stationary combs likewise positioned in said bunker, said combs interacting with said comblike hangers during the turn thereof; sensors of the level of washing disposed in the bunker and generating signals for lowering the movable shelves of the bunker.
Claim 3
Dependent Claim
65 words
A plant according to claim 1, in which the level sensor is made as a feeler kinematically connected to the carriage cam, and the signal for lowering the movable shelves is delivered through the intermediary of a system of levers, one of the levers interacting with a cam plate and the other with the pawl of a ratchet gear adapted for lowering the movable shelf.
Claim 4
Dependent Claim
97 words
A plant according to claim 1, in which provision is made for an element tracking a mark on the washing, said element being connected to the cantilever hangers of the carriages, the compartments of the bunker are equipped with stops, a conveyor with carriages is disposed along all the compartments of the bunker and is mounted in such a manner that it is capable of moving to a position under the bunker movable shelves to unload the latter, the conveyor carriages having combs which, with the conveyor positioned under the movable shelves, are aligned with the latter.
Claim 5
Dependent Claim
37 words
A plant according to claim 3, in which to unload the movable shelves in the course of the alignment thereof with the carriage combs, provision is made of a mechanism for simultaneous lowering of the movable shelves.
Claim 6
Dependent Claim
55 words
A plant according to claim 4, in which the mechanism for simultaneous lowering of the movable shelves is essentially a cam shaft controlled by an electromagnet, the cams of the shaft interacting with pushers extendable into the zone of turning of a lever connected to the feeler of the sensor of the level of washing.
