Abstract

The invention describes a method and an apparatus removing a plurality of die-cut products from an operating area of a die-cutting apparatus having multiple dies. The die-cut products are simultaneously picked up at a pick-up point in the operating area. Then they are simultaneously moved to a delivery point outside the operating area. At the delivery point, the die-cut products are released simultaneously. The operations of picking up moving and releasing are carried out in such a manner that the die-cut products at the delivery point are situated at substantially at the same position with respect to one another as those which they adopt at the pick-up point.

Claims8

Dependent claims

A method for removing a plurality of die-cut products from an operating area of a die-cutting apparatus having multiple dies, comprising the following steps:

substantially simultaneously picking up a plurality of die-cut products at a pick-up point in the operating area;
substantially simultaneously moving the die-cut products from the pick-up point to a delivery point outside the operating area;
substantially simultaneously releasing the die-cut products at the delivery point, the die-cut products being fixed with respect to one another at positions which substantially correspond positions with respect to one another which they adopt at the pick-up point;
and
moving the die-cut products from the delivery point to a discharge point located outside the die-cutting apparatus,
wherein the separate die-cut products are each held at a different position,
wherein the separate die-cut products each follow a different discharge trajectory, and
wherein, at the discharge point, the die-cut products are sorted on the basis of their origin from a specific die.

5 more elements

A die-cutting apparatus comprising:

multiple dies for simultaneously cutting plurality of products out of a base material;
an operating area where the dies are located;
a transfer member which is movable between at pick-up point in the operating area of the die-cutting apparatus above the die-cut products and a delivery point outside the operating area of the die-cutting apparatus, the transfer member being designed to pick up die-cut products at the pick-up point from the dies, wherein the die-cut products come to bear against the transfer member, and to release the die-cut products at the delivery point, the transfer member also being designed to fix the die-cut products with respect to one another at positions which substantially correspond to the positions with respect to one another which they adopt at the pick-up point;
and
a discharge member which extends between the delivery point and a discharge point located outside the die-cutting apparatus, the discharge member being designed to hold separate die-cut products at different positions, wherein the discharge member includes separate discharge chutes, the number of discharge chutes at least corresponding to the number of dies.
