Abstract
A programmer includes an intermittently rotating drum, having thereon a series of actuators arranged in a pre-selected manner, for actuating in a predetermined order, a plurality of devices, such as fluid valves, each of which, when actuated, causes an operation to be performed. The drum is indexed by a stepping motor controlled by impulses of energy to a pilot valve in response to rotation of the drum. The actuators are removably mounted on the drum, so that the programming of the series of operations as to the order thereof, and duration of each, can be done quickly and easily, in advance. Individual valves can also be shut off when not needed.
Claims14
A systems programmer for automatically controlling a predetermined sequence of operations in a machine, comprising a drum mounted for rotation, a series of annular grooves on said drum having annular flanges therebetween, each of said flanges being formed with an annular groove in the periphery thereof and having a plurality of radially extending recesses therein, a series of actuatable members associated with said drum in spaced relation thereto, and positioned along the length thereof, each said member being operable to cause one of a plurality of operations to be performed when actuated, a plurality of cylindrically shaped actuator pins for said members having axially extending end portions of smaller diameter than the central portion thereof, said end portions being removably received in said recesses on said drum along the length thereof in a predetermined arrangement, each adapted to actuate a selected one of said members during rotation of said drum, an annular yieldable ring member recieved in each of said annular grooves in the periphery of said flanges for retaining said actuators therein, and means to rotate said drum.
A systems programmer for automatically controlling a predetermined sequence of operations in a machine, comprising a drum mounted for rotation, a series of actuatable members associated with said drum in spaced relation thereto, and positioned along the length thereof, each said member being operable to cause one of a plurality of operations to be performed when actuated, a plurality of actuators for said members removably mounted on said drum along the length thereof in a predetermined arrangement, each adapted to actuate a selected one of said members during rotation of said drum, a stepping motor for rotating said drum is a step-by-step movement, a plurality of limit switches mounted in side-by-side relation along the length of said drum, each adapted to initiate a signal when actuated to operate said stepping motor to advance said drum, a second plurality of actuators removably mounted on said drum along the length thereof, each adapted to actuate one of said switches when said drum is stepped, means for pivotally mounting each of said switches for rotation between first position for actuation by one or more of said second plurality of actuators, and a second position away from said second plurality of actuators, and a locking bar operatively associated with said switches to lock a plurality of said switches simultaneously in said first position thereof.
