Title:
【発明の名称】梱包機における転倒物品検出器
Document Type and Number:
Japanese Patent JP2000512251
Kind Code:
A
Abstract:
A down-article indicator which automatically adjusts for the height difference of articles, such as bottles, when article size is changed for a new run on a machine conveying articles. A pivotably mounted height sensing arm, located on one lane of the machine, down stream from an array of freely pivoting detecting arms, is connected by an adjustable mechanical linkage to a pivoting bracket holding a retro-reflective photo eye in proper location with respect to the detecting arms so that the detecting arms do not break a light beam from the photo eye during normal operation. A non-upright article will cause a detecting arm to pivot and break the light beam to stop the machine. As a new group of articles having a different height moves into the down-article indicating station, the height sensing arm automatically moves the photo eye to its proper location for the new height articles. The machine has a "prime" mode which overrides a stop signal which may be sent by the photo eye while the transition between groups of articles passes through the station.
