Abstract

The invention relates to a method and to a packaging plant which allows for a high degree of automatization of the packaging of individual product packages into shipment containers of different sizes and which is at the same time highly reliable and according to this method, each one of the product packages is assigned a conveyance tracking clock information, including information about the type of product package, its respective conveyance track, its conveyance speed, and its predetermined position and orientation within the shipment container for the specific shipment order.

First claim

The invention claimed is:

1. A method for placing product packages each containing one or more products into shipment containers of different sizes, the method including the steps of:
selecting and marking a shipment container of suitable size for a specific shipment order in accordance with the specific shipment order;
loading different types of product packages each containing one or more products onto a conveyor system comprising a plurality of separate conveyance tracks;
forwarding information of each respective product package including the type of product package, its respective conveyance track, its conveyance speed, and its predetermined position and orientation within the shipment container for the specific shipment order to a control system at the time the respective product package is loaded onto the conveyor system,
conveying the different types of product packages on the plurality of conveyance tracks to a loading zone comprising at least one loading station each having a pick-and-place robot,
providing the shipment container for the specific shipment order into which the product packages for this order are to be placed within the at least one loading station, the shipment container being arranged in a loading position in which the container is resting still,
picking the product packages for the specific shipment order from the plurality of conveyance tracks and placing the product packages into the shipment container resting still in the loading position within the at least one loading station by means of the pick-and-place robot in accordance with the information in the control system, and
removing the shipment container from the loading station after completion of the specific shipment order.

2. The method of claim 1 , wherein within the at least one loading station a plurality of shipment containers for different orders are resting still in the loading position in side-by-side configuration at the same time, and wherein the pick-and-place robot picks the product packages from the plurality of conveyance tracks and in accordance with the respective shipment order places them into the corresponding one of the plurality of shipment containers resting in the loading position.

3. The method according to claim 1 , wherein the different types of product packages to be loaded onto the conveyor system are retrieved from separate storage facilities in accordance with the respective shipment order, and are loaded onto the conveyor system
( 2 ) by one of automatic and manual loading.

4. The method according to claim 1 , wherein the loading zone comprises a plurality of successively arranged loading stations, and wherein further the information of each one of the product packages comprises an additional information about that loading station of the plurality of successively arranged loading stations in which the automatic picking of the respective product package from the respective conveyance track and the placing of the product package into the shipment container for the specific order is performed.

5. The method according to claim 1 , wherein prior to reaching the loading zone the exact position and rotational orientation of the product packages on the respective conveyance tracks are detected, and wherein data corresponding to the detected position and orientation of the product packages are passed on to the control system for controlling the picking and placing of the product packages to the respective shipment container for the specific order.

6. The method according to claim 1 , wherein within the at least one loading station a said shipment container is transferred from the loading position to an intermediate storage position if within a preselected time period the said shipment container cannot be completed, and wherein the said shipment container is retrieved again at a later time from the intermediate storage position and is transferred back to the loading position for completion of the shipment container once the required product packages for completing the specific order are loaded onto the conveyor system.

7. The method according to claim 1 , wherein each of the product packages contains a single one or a plurality of contact lenses, having the same specific combination of lens parameters.

8. The method according to claim 1 , wherein each of the plurality of conveyance tracks has the same transport speed.

9. The method according to claim 8 , wherein the plurality of conveyance tracks are provided on a single common conveyor belt.
