Abstract
Apparatus for conveying and rotating articles 90.degree. while being conveyed along a predetermined path with rotation being achieved by contacting a forward corner of the article for pivoting it partially as the extending side will be grasped by a side-facing belt to complete rotation and propel the article forward.
Claims6
Apparatus for conveying and rotating a train of articles comprising, in combination:
- a horizontal platform conveyor for carrying each article forward along a predetermined path;
- a bumper positioned in the path of said article to contact a forward corner thereof adjacent a first side of the conveyor to initiate rotation of said article by slowing forward movement of the contacted corner;
- a first side facing belt extending on the second side of said conveyor and supported about pulleys driveably rotated about axes extending upward from the plane of the conveyor, said first side facing belt being positioned to contact and guide the side of said article opposite the bumper for continuing the pivoting of the article about the bumper in a controlled manner;
- first and second fenders on the first and second sides of said conveyor respectively, said fenders being spaced apart a distance slightly greater than the width of the article as it passes therebetween along the conveyor;
- said platform-type conveyor including first and second power driven horizontal belts adjacent said first and second fenders respectively and having a horizontal surface for carrying said articles along said predetermined path;
- means for driving said second horizontal belt at a speed greater than that of the first belt so as to initiate rotation of the article prior to contact with the bumper;
- and
- said first and second fenders being spaced apart a sufficient distance so as to limit rotation of the article due to the differential speeds between the first and second horizontal belts prior to the article coming in contact with the bumper.

- guide means extending parallel to and opposite said first side facing belt and on the first side of said conveyor to terminate pivoting of each article after it clears the bumper in traveling along the predetermined path;
- and
- said guide means including a second side facing belt extending on the opposite side of and parallel to the first side facing belt for guiding the articles along the predetermined path after contact with the bumper.
