  • each batch of folded articles in a particular compartment is taken out and placed on a conveyor belt organ which transports this batch to a wrapping installation. There the batch gets wrapped up in a plastic cover. This repeats itself until each of the compartments has been unloaded. Then all the batches are ready for transportation in a hygienic manner back to where they came from, for example a hospital, a nursing or rest home or the like.
  • WO 2011/1558212 shows such a storage system.
  • a disadvantage with this known vertical Paternoster storage system is that its loading and unloading processes leave to be improved. Both the loading and unloading takes up a lot of time for an employee, particularly because it is performed manually by one and the same person. In order to be able to easily reach all of the compartments during loading and unloading, the operator mostly is taking a standing position behind the shelf of the system. Together with the other actions to be taken behind the shelf, like the folding of the articles, this long-lasting standing behind the shelf makes it a demanding and heavy task to perform. For having the operator being able to keep on concentrating on the job, and not starting to make mistakes because of starting to get tired, it is important that the working conditions are as optimal as possible. However for example lengths of operators may differ considerably.

This working platform is provided sideways in front of the conveying track. For the loading station this working platform makes it possible for the user to perform some kind of action, like folding, to the articles before placing them onto an aimed carrier shelf or carrier shelf compartment.
  • conveying means are provided for moving the plurality of carrier shelves along the track and with those movements passing the shelves along the working platform of the loading and/or unloading station. This makes it possible to each time have a respective one of the carrier shelves stop in front of the working platform of the loading and/or unloading station in between movements of the carrier shelves along the track.
