Method and conveyor for registering articles on a conveyor belt

摘要

Method and a conveyor for registering articles on a conveyor belt. The conveyor includes a registration belt having retractable flights regularly spaced along the length of the belt and article-propelling rollers between consecutive flights. The flights are raised in an upstream portion of the conveyor, and the rollers rotated to propel articles forward against the raised flights. In a downstream portion of the conveyor, a flat-top belt under the conveyor belt runs faster than the conveyor belt and causes the flights to lower and the rollers behind the lowering flights to rotate in reverse to urge the articles away from interfering with the lowering flights.

主权项

1. A method for registering articles on a conveyor belt, comprising:
conveying articles atop rollers in a conveyor belt advancing downstream in a direction of belt travel along an upper run; propelling the articles forward relative to the conveyor belt by rotating the rollers in a forward direction in the direction of belt travel in an upstream portion of the upper run; raising flights disposed at spaced apart positions along the length of the conveyor belt to a raised position in the upstream portion of the upper run to stop the articles being propelled forward at the positions of the flights; lowering the flights in a downstream portion of the upper run; reversing the direction of rotation of the rollers in the downstream portion of the upper run to urge articles away from the lowering flights to allow the flights to lower without being obstructed by conveyed articles.
