A device for setting various operational parameters of combination weighing machine, such as target weight, speed of operation, name of product, allowable range of weight, hopper gate opening time and feed conveyor operation time. In this device, it is only necessary to manually register some independent operational parameters such as target weight and speed of operation from a keyboard and, then, the remaining dependent operational parameters such as hopper gate opening time and conveyor operation time can be registered automatically in accordance with the previously registered independent operational parameters.

Operational condition setting device for combination weighing machine

A combination weighing machine, which is used typically for packing a plurality of articles in each bag or the like so as to render the total weight of each bag to satisfy a predetermined weight condition, including a plurality of weighing units for weighing the articles each at the same time, arithmetic means for selecting some of these units the total weight of which satisfies the predetermined weight condition, and means for unloading the selected weighing units for delivery of the articles for packing and then loading them with new articles; each adjoining pair of weighing units being provided with a common auxiliary hopper for receiving weighed articles from either unit of the pair and keeping them for participating in the combination selecting operation together with those articles on the weighing units, thereby improving weighing accuracy without increasing the number of expensive weighing units.

Combination weighing machine with auxiliary weight hopper

A dispersion feeder for distributively feeding product to a plurality of weighing units arranged circularly about a common axis, comprising a plurality of conveyer troughs arranged radially about the axis for communicating by their outer ends respectively with the weighing units, and a plurality of vibrating units attached respectively to the conveyer troughs for subjecting each conveyer trough to independent vibration. Each conveyer trough is provided with a projection inclined upwardly and radially inwardly toward the common axis. These projections are arranged radially about the axis without mutual contact to form a conical or domed substantially continuous central dispersion surface, and each projection and its corresponding conveyor trough is adapted to be subjected to independent vibration to feed product supplied directly onto the dispersion surface to the corresponding conveyer trough.

Dispersion feeder

An automatic combination weighing machine, having a plurality of weighing units, weighing batches of product or articles by the respective units at the same time and selecting some of the batches exhibiting the total weight meeting a predetermined condition, is provided, wherein each weighing unit is provided with automatic loading and unloading devices and the weighing units are arranged side by side in a line so that the respective loading and unloading paths are parallel to each other, in contrast to the prior machine wherein the weighing units are arranged circularly. This linear type of machine occupies less area than the circular type and can be cleaned easily, and it is more convenient for use in conjunction with soft small product for food, such as meat cutlets and vegetables.
