  • This allows you to take off after taking off for the first time of the object 14 according to the selected distances the suction rollers 30 to each other on the guide, in particular on lifting off the stack 12 and the formation 46 can be influenced.
  • the change the distance of the suction rollers 30 may preferably depending on the angle of attack of the Holding arms 66 take place in the stroke direction 18, so that the change in the inclination of the holding arm 66 with a change in distance of the suction rolls 30 superimposed becomes.
  • Prestressing the objects 14 is here, for example, between the suction roller 30 and the adhesive strap 42 and / or the suction lifter 28 and / or between a plurality of suction rollers 30 and / or the suction lifter 28 and / or the adhesive strap 42 possible.
  • Suction air strength can vary on the one hand Material properties of different objects 14 and on the other hand to a different one Suction air requirement during the separation of the Items 14 can be influenced.
  • the separating device 10 a central control is assigned in for example using a microprocessor matched to different items 14 Characteristic fields are stored, based on which one automatic control of the individual components the separating device 10 takes place. So can for example depending on different Starting materials, for example their thickness, their weight, size or other characteristics automatic adjustment of the movement sequences and individual parameters, such as regulation the suction air, regulation of the speed of rotation the suction rollers 30, control of the drive speed of sub-belt sections 82, regulation the angle of attack of the holding element 66, regulation the distance between two successive detention facilities 26, regulation of the distance between two suction rollers 30 an adhesive device 26 and so on.
  • separation is thus simple the objects 14 with high accuracy and greatest effectiveness and greatest possible separation speed possible.
