Method and apparatus for bunching PTPs and for transferring the bunched-PTPs

摘要

A method and apparatus adapted to bunch together a predetermined number of inverted PTPs and uninverted PTPs into a bundle, and then transfer each PTP bundle to a bucket conveyor which moves intermittently in parallel with a conveying passage. A multitude of PTPs, a portion of which are inverted with respect to the conveying direction and the rest of which are not inverted, are conveyed along a first conveying passage while maintaining the blistered surfaces of the inverted and uninverted PTPs in parallel with each other. A selected portion of the PTPs being conveyed in the first conveying passage is pinched and separated from the same passage. The separated PTPs are bunched together while the spacing between the separated PTPs is narrowed in the conveying direction. The bunched PTPs are transferred onto a second conveying passage across the first conveying passage. The bunched PTPs are loaded into a bucket provided on a bucket conveyor which intermittently travels along the second conveying passage.
