ABSTRACT:
The present invention relates to container inspection machines.
BACKGROUND OF THE INVENTION
When an inspection device inspects an object such as a glass container, there is a fixed period of time in which a specific inspected bottle must be removed from a transporting conveyor by a rejector.
In a real-time computing environment a control, at the time an inspection is made not only knows where the bottle is but knows how long it will take to reach the rejector. Accordingly, when the decision is made that a bottle is to be rejected, the time until rejection will be counted and the rejector than fired to remove the bottle.
In a non-real-time computing environment this continuity does not exist. For example, in a MICROSOFT WINDOWS computing environment, things do not occur at known times. Rather things happen in accordance with preselected priorities.
OBJECT OF THE INVENTION
It is accordingly an object of the present invention to adapt such a system so that it will, in effect, operate real-time.
Other objects and advantages of the present invention will become apparent from the following portion of this specification and from the accompanying drawings, which illustrate in accordance with the mandate of the patent statutes a presently preferred embodiment incorporating the principles of the invention.
