Work station for a packaging machine and tool changing method

摘要

The present invention relates to a work station for a packaging machine, comprising an upper tool and a lower tool arranged below the upper tool. These tools are configured for acting on a packaging web. A lifting unit is able to move the upper tool and/or the lower tool such that, at a specific position, the two tools abut on one another or are only spaced apart at a small distance. According to the present invention, the two tools are adapted to be coupled to one another by a releasable coupling at this position so that they can be removed from the work station in common. The invention also relates to a corresponding method for removing a lower tool from a work station, e.g. for the purpose of tool exchange.

1. A work station for a packaging machine, comprising an upper tool and a lower tool arranged below the upper tool, wherein said upper and lower tools are configured for acting on a packaging web, and wherein a lifting unit is provided for moving at least one of said upper and lower tools between at least one lowered position and at least one raised position, so that, in one of said two positions, said upper and lower tools abut on one another or are spaced apart at a smaller distance than in the other position,
wherein in the position in which the upper tool and the lower tool abut on one another or are spaced apart at a smaller distance than in the other position, said upper and lower tools are adapted to be coupled to one another by a releasable coupling, wherein the releasable coupling is actuatable between an uncoupled state in which the upper tool and the lower tool are uncoupled and in which the lifting unit only moves one of the tools, and a coupled state in which the upper tool, the lower tool, and the releasable coupling can be removed from the work station in common.
