Abstract
A variable insertion rate control system for a component insertion machine is disclosed. An insertion rate is read and retained by the control system which thereafter authorizes insertion of components at the indicated insertion rate. In order to achieve relatively high insertion rates, the downward stroke of the component insertion head is commanded before the receiving medium is registered in position for receiving the component.
Claims15
In an electrical component insertion machine wherein electrical components are selectively inserted into a receiving medium positioned beneath a component insertion head, a system for controlling the rate at which the electrical components are inserted, said system comprising:
- means for verifying that the receiving medium has reached a position relative to a final commanded position whereby only a finite, predetermined distance remains to be traveled by the receiving medium in at least one direction;
- and
- means, responsive to the verification, for initiating an insertion stroke by the component insertion head during the time in which the finite predetermined distance is being achieved.
A control system for controlling the rate at which electrical components are inserted into a receiving medium that is positioned relative to a component insertion head in response to a set of commanded movements said system comprising:
- means for defining a constant period of time between successive insertions of electrical components into the positioned receiving medium;
- means for monitoring the commanded movements so as to define when predetermined amounts of commanded movement remain to be executed;
- and
- means for authorizing a downward movement of the component insertion head when only the predetermined amounts of commanded movement remain to be executed and the constant period of time has elapsed between successive insertions of electrical components.
