Description

Technical field

The present invention relates to a method and a device for packaging plate-shaped Workpieces that are combined into workpiece stacks and in packaging is brought in.

State of the art

Various methods for Packaging of plate-shaped workpieces or from them formed workpiece stacks known. At a first The process is carried out at the end of a conveyor line on which the plate-shaped workpieces are promoted Packing box provided in which the workpieces directly and individually one above the other. The workpieces fall depending on the filling level of the packaging to different heights in the carton, resulting in a insufficient alignment of the workpieces and possibly lead to damage to the workpieces or the carton can. In addition, this procedure comparatively time-consuming and clock-dependent. As soon as namely a box with the desired number of workpieces is filled, it must be from the filling position be transported out and there must be an empty box in the Filling position can be transported. During this No workpieces from the conveyor line in the filling position are promoted. This means that the The distance between the workpieces on the conveyor track is relatively large Must be so that the packaging capacity of the device (expressed, for example, as packaged workpieces per Minute) is limited.

In a further known procedure, the Workpieces are combined in stacks and on an inclined one Conveyor line at an angle into a provided box inserted. There is a risk that the Insert the cardboard, especially its side wall, through the impact of the workpiece stack is damaged. The same also applies to the workpieces themselves unsatisfactory alignment of the workpieces.

As an alternative to feeding the workpiece stack at an angle it also known to stack the workpiece in via a hopper bring in a provided box or the box to put over a provided stack, whereby especially in the latter method, a tilting of the Cartons and the workpiece stack occurs. Overall is at all known methods to determine that they are a unsatisfactory packaging capacity or Show packaging speed.
