Method for filling bags with granules

Abstract

The invention relates to an apparatus and a method for filling bags (34) with granules. The invention also relates to a support element (1) for supporting a bag (34, 36) during filling, the support element (1) being in the form of a pitched roof, and means (24) for fastening to a transporting belt (10) being arranged on the underside of the support element (1).

Description

[0001]The invention relates to a method for filling bags with granules by way of a filling plant, and also to an apparatus for filling bags with granules, wherein a bag is supported by support elements during filling.PRIOR ART[0002]Bulk materials generally have to be filled into containers and packaged for transport. Bulk materials are, for example, sand, powder and granules of various materials. In the present description, the general term granules is used for all of these bulk materials.[0003]For transport, granules are packaged in particular into silo trucks, big bags, corrugated board octagonal containers and bags. With a silo truck, very large quantities of bulk material can be transported at once. However, the bulk materials are increasingly being requested in smaller units. Big bags and corrugated board octagonal containers provide disposable and reusable containers having a large capacity, typically between 500 and 2000 liters. However, the bulk materials are increasingly be...

Benefits of technology

[0032]The method is suitable for bags of various sizes and makes it possible to set the length of the bag freely.

[0033]On account of the support element according to the invention, an apparatus for filling bags with granules can be improved such that the filled bags can be brought into an approximately cuboidal format by pressing. Thus, better space utilization is achieved in palletizing downstream of the filling of the bags and the stackability of the filled granule bags is improved. As a result, it is possible to accommodate the bags on a pallet in more layers than has hitherto been possible. The number of pallets required for transport is reduced, thereby lowering expenditure and costs of logistics.

[0034]The advantageous configuration of the support element according to the invention with a holding apparatus makes it possible to fasten the support element to a cleated conveyor belt, as is usually used in apparatuses for filling bags with granules. On account of the selection according to the invention of the maximum height of the support elements, no further alterations or modifications to the apparatus for filling bags with granules have to be carried out apart from the fitting of the support elements.

Problems solved by technology

A disadvantage of this method is that the bags filled in this way deviate considerably from the optimum cuboid shape and as a result the stacking property of the bags is impaired.

Furthermore, space is not utilized optimally, since unused hollow spaces remain to a relatively great extent between the bags.
