Abstract
Abstract Distribution of filled bags of solids after bag sealing is obtained without interruption of flow by discharging bags from a constantly moving conveyor by means of an air-cylinder-powered discharging member which swings transversely across the conveyor in response to actuation of a flexible microswitch actuating arm by the moving bag, thereby transferring the bag to a second constantly moving conveyor. An electrical counting and control system may be used so as to discharge the desired number of bags at any one of several such discharging stations.

Claim 1
Independent Claim
204 words
The combination with a constantly moving conveyor for filled bags of solids of: a. a sensing device consisting of a flexible actuating arm attached to an electrical switch, said flexible actuating arm being positioned in the path of said filled bags so that as the bag passes along the conveyor the flexible arm is swept aside without substantially interfering with the movement of the filled bag or the conveyor; b. a conveyor discharge device consisting of a downwardly disposed pivoted member positioned adjacent to the constantly moving conveyor so as to swing transversely across the constantly moving conveyor, said pivoted member having attached thereto an actuating device consisting of an air-powered piston and cylinder and air supply control means responsive to the electrical switch sensing device, so that actuation of the electrical switch by a filled bag on the conveyor results in swinging of the pivoted member transversely across the constantly moving conveyor, discharging the bag therefrom; and c. a second constantly moving conveyor positioned horizontally and with a direction of travel at substantially 90* to and away from the direction of travel of the first conveyor and directly across from the discharge device so that discharged bags are received by the second conveyor.
