ABSTRACT:
Apparatus is provided for controlling the operation of a radial stacker which is adapted to dispense aggregate material in the form of a stack. The radial stacker includes a conveyor for dispensing the aggregate material which moves horizontally through a plurality of dispensing positions to form a level of the stack, and which moves vertically through a plurality of levels to form the stack. One end of the conveyor is supported at a fixed pivot so that it is capable of traversing a horizontal arc of up to 340.degree.. Preposition switches are provided so that the operator may manually set the vertical and horizontal starting point of a cycle. A horizontal drive moves the conveyor horizontally to each position in a level and is controlled by a first timer. A second timer controls the amount of time that the conveyor spends at each of the positions in a level dispensing material. A vertical drive moves the conveyor in a vertical direction to each level to be formed in the stack and is controlled by a third timer. Horizontal and vertical stepping-drum programmers are provided for controlling the sequence and operation of the first, second, and third timers. The radial stacker of the present invention is capable of operating in either a continuous or intermittent mode as it moves through the positions of each level. To operate the radial stacker in the continuous mode, it is only necessary to set the first and second timers at their zero settings.
