Abstract
A sensing device is provided which increases the versatility of sorting and conveying systems employing the device while simplifying their construction. The sensing device comprises a weight sensor and means for at least momentarily causing the weight of an article to apply a force directly or indirectly to the weight sensor.
Claims4
A weight sensing device for use with apparatus for sorting articles which are moving along a path, comprising:
- a. an electronic transducer arranged to emit a signal related to the weight of each article sensed by the device as each article moves through a weighing station located along at least a portion of said path,
- b. at least one member rotatable about a fixed axis at said weighing station and including means to both receive and support each article as said article passes through said weighing station, and
- c. means to transmit a load to said transducer and positioned in the path of said rotatable member such that said rotatable member while supporting said article must rise and ride over said means to apply its load to said means and transducer.
Apparatus for weighing articles which are moving in succession along a path, wherein said path includes a bend therein, said apparatus comprising:
- a. a weight sensor adapted to emit a signal related to the weight of each article in succession,
- b. means disposed at said bend in said path and connected to said weight sensor for at least momentarily causing the weight of each article as it moves along said path to apply a force directly or indirectly to said weight sensor,
- c. a conveyor extending along said path, and
- d. means suspending said articles individually from said conveyor whereby said articles are caused to swing outwardly and radially of said bend as they move around the bend, thereby increasing the spacing between said articles.
