Abstract:
Wlien products are combined by weighing in order to obtain a given portion, use is made of scales with several discharge units, and the portion may be placed along a length of conveyor belt. A pack at the end of the conveyor belt is not filled until the whole portion has been conveyed. According to the invention this may be performed faster, in that the portion is distributed partly across the width of the conveyor belt, and the receiveing open packs are conveyed synchronously along the end of the conveyor belt during the whole arrival time of a portion.
Abstract:
Certain types of fragile goods, such as certain fruits must be handled very gently, which reduces the capacity of weighing or sorting apparatus. According to the invention the capacity of existing plants may be increased considerably by using two conveyors (8, 9) and by performing a gentle depositing alternatingly on the two conveyors. The gentleness is obtained by a particular geometry (3, 4, 5, 6, 7) for the kinematic movement of intermediary collecting elements (3, 4) between the weighing and sorting apparatus and the conveyors.
Abstract:
Packing large rounded articles in smallish bags requires singulation. According to the invention, a full portion is released at the upstream end of a V-shaped structure created by conveyor belts. The V-shaped structure carries the rounded articles to the packing station. At the beginning of the operation, a section of one side of the V-shaped structure is prevented from contributing to the forward transport of the articles, and they are rotated by the other side of the V-shaped structure. As the operation proceeds while the portion is broken up, the inactive section of the conveyor belt is made active, and the articles are now carried singly at full speed to the packing station.
Abstract:
An outermost packaging bag (2) of an ordered store (1) of flat-laid bags made of flexible plastic foil is opened by a vacuum being selectively applied during restraint of the bag (2) against the store (1) for suction and lifting free of a local area (12) of the outward wall (4) of the bag without movement of the opposite inward bag wall. The area (12) lifted free is restrained by clamping so that at release of its restraint against the bag store, the outward bag side (4) can be moved away from the inward wall.
