Abstract

A process is defined for controlling the feeding and dosing of granular products supplied to the loading hopper (31) of a sacking machine (30) in a packaging plant from a plurality of storage containers (2, 3), aimed at sacking the same products in corresponding batches of sacks (1). First weighing machine (35), provided near the loading mouth (36) of the hopper (31), is aimed at weighing the product contained in the sack (1) being filled. The process includes the following working steps: definition of the number of sacks (1) of each batch; opening an outlet valve (Vul), and a feed valve (Val), so as to allow the product to reach the hopper (31). The weight of the product present in the loading hopper (31) is monitored by means of a second weighing machine (32), provided in the latter. Thus, the filling operations of the sacks (1) are carried out until a predetermined portion of the batch of the product, with corresponding opening and closing of the outlet valve (Vul) and/or of the feed valve (Val), to maintain a known amount of product in the hopper (31). When the fraction of the packaged product is reached, the opening of the outlet (Vul) and feed (Val) valves is modulated to maintain in the hopper (31) the exact remaining amount of the product sufficient to fill the sacks (1) necessary to complete the batch.
