- The present invention relates to a weight filling machine suitable for filling containers with two or more products of different type.
- A particularly felt problem in the field of filling machines, in particular of weight filling machines, is the one of filling containers with products of different type to form a composition. A typical example occurs for household products such as detergents for home hygiene, for washing clothes and similar products. It is indeed known that such products comprise a base composition, which typically amounts to about 99% of the weight of the product, and fragrances and/or dyes which are added to the base composition to give the product a range of different organoleptic features so as to please different user tastes. For example, a detergent may be introduced to the market with a pink color and a rose scent, or have the color and scent of lavender, and so on.
- The production of these diversified products requires first preparing the different mixtures of substances and then filling the containers with such mixtures, by operating for example by successive lots, each with a different product. This requires interrupting the filling process between one lot and the other to wash the equipment.
- Alternatively, machines exist which are capable of simultaneously filling containers with mixtures of different products, by drawing from diversified tanks, one for each product, but managing the filling procedure is complex and the bulk of the equipment is significant.
- The problem addressed by the present invention therefore is to provide a filling machine, in particular a weight filling machine, which allows optimally managing the simultaneous filling operation of containers with diversified products and which has a reduced bulk.
- Such a problem is solved by a filling machine as outlined in the appended claims, the definitions of which form an integral part of the present description.
- In particular, the invention relates to a weight filling machine comprising a filling unit and a supply unit for one or more products of different final composition for filling containers, where said one or more products comprise the same base composition for all the products and one or more additives, different for each different final composition, where the supply unit comprises a tank for the base composition and a plurality of mixing units, one for each different product, each of the mixing units being connected by means of respective supply lines to the filling unit.
- Further features and advantages of the present invention will become more apparent from the description of certain embodiments thereof, given below only by way of non-limiting, indicative examples.
