AbstractThis apparatus employs a pair of proximity sensors to check a particular dimension of a particular article being processed for further operations. Those articles that do not meet dimension tolerances are removed from further processing.
This apparatus employs a pair of proximity sensors to check a particular dimension of a particular article being processed for further operations. Those articles that do not meet dimension tolerances are removed from further processing.
A vibrating bowl, drawing A, supplies articles to a nibbed conveyor for delivery to the first sensing station and a pneumatically driven sorting apparatus. All sensing stations are the same in construction and in operation. Each sensing station comprises a proximity wheel, drawings B and C, each including a magnetic element that cooperates with a superposed sensing head. The proximity wheels are adapted to be raised by the article as it is carried beneath them by the conveyor belt. Simultaneously, the magnetic element is brought beneath the sensing head. One proximity sensor monitors the maximum thickness of the article. The other sensor monitors the thinness of the article. An article having dimensions outside the dimensions monitored by the sensing heads initiates a signal. The latter is supplied to the pneumatic operated sorting equipment. The article is ejected by the sorting equipment when triggered by a signal from the sensing device. Those articles, which are not rejected, are collected in a hopper, not shown, for further processing.
The second sensing station is adapted to monitor another dimension of the article, e.g., length, width, or height. This is effected by appropriately altering the position of th...
