Installed and loaded with suction air by a suction air supply device (not shown) Is done. As shown in FIG. 6, a plurality of sheet paper transporting devices 4 are independent of each other and endless. of It circulates in the guide rails 6a and 6b, and in this case, the control / adjustment device 30 is driven. By controlling and adjusting stations 8a and 8b as follows, The speed is strongly reduced upon reaching the trailing edge 86 of the sheet pile 82, which is advantageous. Stopped and, as a result, at the start of the Soccer 84 or of the suction air supply device At the time of connection, the relative movement between the sheet paper 2 to be adsorbed and the soccer 84 is quite young. It rarely occurs. Sheet paper 2 to be transported is adsorbed by soccer 84 The speed of the transfer device 4 according to the present invention after being lifted from the pile 82 (position X). The degree is increased, and the sheet of paper 2 transported by the transport device and, by extension, the transport device is The shear stacking speed (Schuppengeschwindigkeit) required for stacking paper feed Occupy. In this case, the acceleration of the transport device 4 based on the present invention is advantageously uniformly performed. The weight required for the conveyed sheet 2 to shut off the suction air supply device (position Y). It is the size that occupies the speed. Control after shutting off the suction air supply at position Y The coordinator 30 advantageously controls the speed of the sheet transfer device 4, i.e. The speed of the sheet paper carrier is increased first, then the trailing edge 86 of the sheet sheet pile 82. Just before reaching, it is reduced again in the form described above. In all the above-mentioned examples of the sheet-sheet transport mechanism 1 based on the present invention, the sheet-sheet transport Feeding can be done exclusively by the only sheet paper carrier 4. But However, in an advantageous manner, a large number of sheet paper transporting devices 4 are used in the guide rails 6a and 6b. The same movement is produced in each sheet paper transport device. The sheet paper transport mechanism 1 based on the present invention first describes an embodiment of a sheet paper rotary printing press 3. Although stated, the sheet-fed transport mechanism is a known roll-up press (Rol) in the same format. In the lenrotations druck maschine, for example, a wave pulling device (Bahneinzugsvo) It may be used as rrichtung). In this case, there are not necessarily two opposing guide trays. There is no need to use a rail, and one guide rail with one propulsion element is used. -It is enough to place it along the lead-in path, and the paper web to be pulled in The leading end of the probe is fixed, for example, to the protrusions 20a, 20b. This is the invention of the present invention It does not deviate from the underlying principles. In addition, the propulsion element of the transport mechanism is a follow-on processing device (Wei) for printed products. terverarbeitungsanlage), eg, a transfer gripper (Tr in a binding device, or folding device) It can also be used to drive ansportgreifer).
