• the present invention relates to a plastic card separation system for a plastic card processing machine, as well as a processing machine comprising such a separation system.
• each plastic card must undergo one or more treatments before being broadcast.
• a treatment can consist of printing patterns, photos, characters, etc. on one or both sides of the plastic card.
• Another treatment may consist of a magnetization of a magnetic strip present on one face of the plastic card, or an initialization of a chip present on one side of the plastic card.
• a processing machine comprises a frame on which is mounted a reservoir containing the plastic cards to be treated, at least one processing module for processing each plastic card, and a receiving magazine containing the processed plastic cards.
• the processing machine also has a separation system which is provided to take a plastic card in the tank by separating it from the rest of the stack.
• An object of the present invention is to provide a separation system which does not have the drawbacks of the prior art and which in particular remains efficient regardless of the thickness of the plastic cards to be treated.
• a system for separating a lower plastic card from a stack of plastic cards comprising:
• a loader roller on which rests a first end of a lower plastic card, and having at least one groove extending parallel to the axis of said loader roller, on its periphery and over its entire length,
• a movable assembly disposed above the loader roller and comprising a base and a loading roller mounted free to rotate on the base, said base being movable vertically between a contact position in which the loading roller is in contact with the roller charger and a spread position in which the loading roller is remote from the loader roller, and
• the base having an upstream wall which extends upstream of the loading roller, and whose lower end is, in the contact position, at a distance from the loader roller lower than the thickness of the lower plastic card, and
• the or each groove having an opening and a depth sufficient to allow the first end of the lower plastic card to descend into said groove so that its first end passes under the lower end of the upstream wall, the opening and the remaining depth, however, such that despite the fall of the first end of the lower plastic card, the first ends of the other plastic cards remain in abutment at the rear of the upstream wall.
• the invention also proposes a plastic card processing machine comprising a frame on which is mounted a reservoir containing a stack of plastic cards to be treated, at least one treatment module intended to treat each plastic card, and a separation system according to the previous variant and arranged between the reservoir and the or one of the treatment modules.

• the separation system 150 has a loader roller 152, a moving assembly 154 which is disposed above the loader roller 152 and a return means 156.
• the moving assembly 154 comprises a base 158 and a loading roller 159 rotatably mounted on the base 158 which is here subjected to the return means 156.
• the base 158 takes the form of a yoke inside which is mounted the loading roller 159.
• the moving assembly 154, and more particularly the base 158, are mounted on the frame, and are movable vertically with respect to the loader roller 152 between a contact position (Fig. 1) in which the loading roller 159 is in contact with the loader roller 152 and a spaced position (Fig. 2) in which the load roller 159 is remote from the loader roller 152.
• the contact position corresponds to the case where no plastic card C is between the loader roller 152 and the loading roller 159
• the spaced position corresponds to the case where the lower plastic card CO is between the loader roller 152 and the idler roll. loading 159.
• the moving assembly 154 is constrained in the contact position by the return means 156 which takes for example the shape of a spring.
• Each plastic card C has a first end C1 and a second end C2.
• the first end Cl comes into contact with the separation system 150 and the second end C2 is remote from the separation system 150 and rests on a support 162 of the tank 160.
