Description

Method and device for sorting piece goods into roller containers Technical Field The invention relates to a method and a device for sorting pieces into a roller container (Rollbeh ä lter), comprising a pallet (Ladebode) which can be moved over rollers and two side walls which are arranged opposite one another and laterally delimit a loading space for the roller container for pieces, which side walls extend upwards from two opposite edge sections of the movable pallet. Background Document DE102018203336A1 describes a device for sorting loaded piece goods into a roller container, wherein the roller container has a loading floor and at least one lateral grid wall, which device has a sorting deck, a sorting bin, which extends to a sorting plane on the sorting deck, on which the piece goods move during sorting, a lifting device for lifting and lowering the roller container in the sorting bin, a flap (Zunge) which can be laterally entered and exited from the sorting bin for loading the piece goods, a device for lowering the flap stepwise during loading of the piece goods such that the upper surface of the piece goods layer finally placed on the flap is approximately at the level of the sorting plane, and a discharge device (Abstreifmittel) for discharging the piece goods from the upper side of the flap onto the loading floor of the roller container at least when the flap is exited from the sorting bin. Disclosure of Invention The object of the invention is to provide a method and a device for sorting pieces into roller containers, wherein a piece goods stack formed on a loading flap can be automatically placed onto a pallet of the roller container without interference. The object of the invention is achieved by a method for sorting piece goods into a roller container, which comprises a cargo floor that can travel on rollers and two side walls that are arranged opposite one another and laterally delimit a loading space for the roller container for piece goods, which side walls extend upwards from two opposite edge sections of the cargo floor that can travel, which method comprises the following steps: Automatically driving the loading tongue into the sorting bin, the loading tongue being supported in a height-adjustable manner inside the sorting bin; -automatically loading the loading flaps with pieces of goods so as to form a stack of pieces of goods inside the sorting bin; -introducing the stack of pieces arranged on the loading flap at least substantially vertically from above through the upper opening of the roller container into the loading space of the roller container; in the case of holding the stack of pieces in the loading space of the roller container, the loading flap is pulled out laterally from the loading space of the roller container, so that the loading flap is removed from the loading space of the roller container and the stack of pieces is placed on the loading floor of the roller container; During the vertical introduction of the component stacks arranged on the loading lugs into the loading space of the roller container and/or during the lateral withdrawal of the loading lugs from the loading space of the roller container, the component stacks are laterally supported in at least one height section and/or in at least one width section of the component stacks by automatic feeding and/or pressing of the feeding device onto the component stacks on at least one side of the component stacks. Sorting bins are commonly used to build stacks of pieces on a layer-by-layer basis. At the level of the sorting plane, the piece goods are removed from the sorting plane individually or in groups of several articles layer by layer or piece by piece and placed on the loading flaps or on the piece goods stack being constructed. To simplify handling of individual or whole or partial layers of parts, after the construction of a layer of parts is completed, the partially loaded stack of parts is lowered inside the sorting bin so that a new layer of parts can be constructed on the stack of parts being constructed. The side walls of the sorting bin should form a boundary for guiding the (partial) stacks of the finished products. However, the problem is that the sorting bin must have a clear width that is at least large enough so that the cargo floor can be lowered inside the sorting bin. In many cases, however, the constructed stacks of pieces are formed with the bottom area of each layer thereof smaller than the bottom area of the pallet, so that the pieces of the stacks of pieces will be significantly farther away from the side walls of the sorting bin, even if the sorting bin walls are reduced to a size corresponding to the bottom area of the smaller pallet of the roller container. However, such sorting bin walls cannot be narrowed beyond the outer contour of the pallet of the roller container in the direction of the stacks of pieces, since the pallet would prevent this. There is thus a risk that individual pieces m
