| 12 | Method and device for recording the flow rate of a stream of bulk material | US617400 | 1990-11-20 | US5121638A | 1992-06-16 | Bruno Gmur |
| The invention proposes a novel weighing method and a device for exactly determining the weight of a continuous stream of bulk material. The stream is conveyed without interruption into a tubular weighing machine (1). A blocking slide valve (4) is cyclically closed and opened and the weight increase per unit time is measured, the slide valve (4) being closed in each case, and an average is obtained from a very large number of weighing operations repeated in the same manner, and is used by computer means (5) for calculating the entire amount of bulk material. The weighing cycle is very short, in some cases less than 10 seconds, and is continuously repeated. The large number of measurements gives high statistical accuracy of about .+-.0.02%, i.e. of the same order as for a container-type weigher. | ||||||
| 13 | Box Filler for Produce Packaging | US14295484 | 2014-06-04 | US20150353212A1 | 2015-12-10 | Robert L. Williamson |
| A “weigh/fill” type box filler for cherries, cherries and similar small produce that incrementally moves and fills an array of individual packaging bags within conventional packing boxes. The box filler includes a box conveyer, a producer conveyer, a metering gate, a weigh/fill scale assembly and three independent box lifters. The box conveyer moves the packing boxes incrementally over the weigh/fill scale assembly to position each row of bags within successive packing boxes beneath the metering gate. As one packing box is incrementally moved across the weigh/fill scale assembly and each row of bags is weigh/filled, the box lifters sequentially raise the adjacent preceding and following packing boxes out of contact with the weigh/fill scale assembly. The metering gate uses independently actuated gate paddles to selectively control the flow of produce into the individual bags first at a high volume “gross” fill rate and finishing with a lower volume or “fine” fill rate. | ||||||
