A method for operating a goods presentation a direction as well as lifting device for a goods presentation of a device for carrying out the method

摘要

A goods presentation a direction (11) contains a lifting base (33), which is arranged above one another, by means of pressurized fluid supply up to a height of expandable lifting pad (32) is supported. Each lifting pad (32) are associated with a control valve and a pressure sensor, which are connected to a control unit. In an automatic program sequence is a pad (32) to a pressure fluid to the total weight of corresponding reference value, for example, which for each lifting pad (32) a switching pressure value in accordance with the formula # # is calculated (n, the total number of lifting pad (32) and n is the in the sequence of the application of the respective lifting pad new number). In the case of falling below the switching pressure value by means of the removal of goods, the pressurized fluid supply to the respective lifting pad (32) is released, to its height is reached and a pressure increase occurs, in which the pressurized fluid supply is interrupted and to the next lifting pad (32) is released. The pressurized fluid supply to the next lifting pad (32), in the event of switching pressure value is interrupted and later, when the fluid pressure the switching pressure value falls below by means of the removal of goods, for the purpose of expanding of the next lifting cushion (32) is released again.
