ABSTRACT:
The present invention relates to glass bottle inspection equipment and more specifically to equipment for removing defective bottles from a conveyor before they can be confused with good bottles.
BACKGROUND OF THE INVENTION
Glass bottles are conventionally formed in an I.S. (individual section) machine. The process is complex and the formed bottle can have a number of defects. Formed bottles are displaced by a conveyor to a packing location. Inspection equipment identifies bottles with these defects and a reject mechanism which will know when the defective bottle is in front of it, will remove a defective bottle from the conveyor with an air jet or with a kicker mechanism.
OBJECT OF THE INVENTION
It is accordingly an object of the present invention to provide a bottle reject system which will be more efficient in rejecting bad bottles.
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.
