Estimating the term…
A combinational weighing system with a plurality of article batch handling means has an article feeding means for feeding articles to be weighed into the individual article batch handling means, and after a desired combination or weights within a preselected range is determined by a computer, the article batches from the selected article batch handling means are discharged together to be made into a package. The system also includes a means for measuring the weight of the article accumulated on the article feeding means and the output signal from such a weight-measuring means is transmitted to control the operation of a conveyor for supplying the articles to the article feeding means.
An automatic weighing system comprising
In an automatic weighing system including a hopper with a gate and a linkage system directly connected to said gate for controlling the motion thereof, a hopper gate operating means comprising a drive shaft adapted to rotate around its axis, a cam mounted on said drive shaft, and a rotatably supported lever means having a first end in an engaging relationship with said cam and a second end which moves along a circular orbit and can be separated from or pressed against said linkage system in an arcuate movement.
In an automatic weighing system which includes a plurality of hoppers arranged in a circular array, each hopper comprising a linkage means and a gate, said gate being adapted to be opened by application of an external force on said linkage means, a motor, a central gear connected to said motor, a plurality of gate control means each associated separately with one of said hoppers, each of said gate control means including a pinion engaged to said central gear, a drive shaft affixed to and adapted to rotate with said pinion, a cam mounted on said shaft through a cam control means which includes a clutch and a brake, a cam lever having a cam follower engaged with said cam, and a lever support means for supporting said cam lever rotatably, said cam lever being adapted to compress said linkage means.
In an automatic weighing system having article batch handling means, a hopper comprising a main body defining an article receiving upper opening and an article discharging lower opening, a gate adapted to swing with respect to said main body and to close said article discharging lower opening, a bracket secured to and extending from said main body, and a linkage means for linking said gate rotatably with said main body, said linkage means being secured at one end to said gate and rotatably affixed to said bracket around a pin to define an axis of rotation along said pin external to said main body, said linkage means containing a toggle means and being adapted to be subjected to an external force for opening said gate.
