Device and method for conveying sheets and conveyor system

Device for conveying sheets of paper, cardboard, or plastic along a transport path, the device comprising:

• a control device configured to control a conveyor process;
• at least a first conveyor belt provided with first air channels;
• and
• at least one pneumatic device connected to the first air channels of the conveyor belt, the control device being configured to actuate the pneumatic device, which is configured to transfer air through the first air channels so that sheets forwarded from an input device are pneumatically coupleable to and de-coupleable from the conveyor belt at an output device (12), wherein
• in a transport path between the input device and the output device, at least a first intermediate buffer is arranged, the first intermediate buffer being configured to receive and deliver said sheets;
• and
• the input device, the output device, and the first intermediate buffer are positioned adjacent to the first conveyor belt and operated by the control device in such a way that sheets forwarded from the input device or sheets stocked in the first intermediate buffer are coupleable pneumatically to a lower side of the first conveyor belt, and that sheets pneumatically attached to the lower side of the first conveyor belt are selectively decoupleable at the intermediate buffer or at the output device.
