ABSTRACT:
An improved apparatus for automatically merging articles being transported along a first conveyor line among articles being transported along a second conveyor line. The apparatus senses the proper positioning on the first conveyor line of an article to be merged among articles on the second conveyor line by means of a pneumatic proximity switch which provides an air output signal through a fluid amplifier valve to a cylinder actuating valve which causes two fluid power cylinders to extend, one power cylinder to transfer the sensed article from the first conveyor line to the second conveyor line and the other power cylinder to interrupt the conveyance of articles along the second conveyor line during such transfer. A cam actuated air switch is tripped upon full extension of the article transfer fluid power cylinder to cause automatic retraction of both power cylinders. Both the sensing and actuating elements of the apparatus are pneumatically operated.
