To expand capacities, the firm recently installed in its Oss facility in the southern Netherlands a multi-head weigher Model MP 24-1000/400-H-S5 from Multipond for mixtures of up to four different components. This is the ninth Multipond weighing machine installed by Vetipak.
The products to be weighed are fed to the weigher by four Multipond cross head feeders. Once they have arrived on top at the weigher, the products are first conveyed to the prefeed hoppers by the radially positioned feed trays and then to the weigh hoppers underneath. The system operates based on the principle of combining partial portions. After the weighing process, the partial portion is deposited via specially-developed swiveling funnels into the memory hopper underneath. The use of the memory hoppers greatly increases the number of possible combinations and ultimately provides the basis for maximum accuracy and speed. A computer now determines, from the partial portions, the combination that corresponds to or comes closest to the desired target weight. Depending on application, the finished weighed portions are finally delivered to the timing hopper, from which they are transferred to the downstream form fill seal machine.
