Electro-pneumatic sheet sensors such as ffelkolben) or detection sackers (Abfragesauger) or electro-optical sheet sensors such as, for example, reflected light detectors (Reflexlichttaster) are used. The paper sensor detects the presence of a leading or trailing edge at one or more locations on the everting device. If no sheet is detected, printing is interrupted.

サ汚染の問題を完全に排除することもできない。For reliable and reliable functioning, the sensors must be arranged relatively close to the sheets passing by. Since the front-printed sheet side is facing outwards in the storage cylinder, fresh or freshly printed printing ink can rub against the sensor and cause print stains. The risk of this print smear increases as the flutter of the sheet increases. The print stains due to such abrasion not only damage the printed surface just printed, but also stain the sensor. Therefore, opto-electric sensors in particular require frequent cleaning. To avoid print smears, air-assisted sheet guide plates were used, but such sheet guide devices not only increase the production costs of the printing press but also completely eliminate the problem of sensor contamination. Can not be excluded.

左右されるので、頻繁な調整作業が必要である。Electropneumatic sensors are certainly less sensitive to contamination than electro-optical sensors, but are relatively expensive mechanically. Moreover, the responsiveness of such a sensor depends on the printing speed and the type of printed matter, and requires frequent adjustments.

It can only be installed where there is only a very short time window, in which case printing interruptions likewise occur relatively slowly.

In this case, it is further necessary that all printed materials (glossy paper, sheet, black paper, etc.) can be reliably recognized.

By changing the angle, the time window for recognizing the sheet can be changed. For example, a steep angle increases the time window. In such an arrangement, the sheet can be recognized more reliably than in the case of a light beam extending parallel to the sheet surface. By arranging the light transmitter and the light receiver as in the present invention, sheets arriving on horizontally displaced planes can also be advantageously recognized.

The light, e.g., infrared or red light, sent from the transmitter is hit by a triple-reflector provided on the other side of the printing press and reflected towards the receiver casing provided on the transmitter. You. If the object interrupts the light beam, that is, if the sensor does not receive light, the sheet is detected. The transmitter is
It has a polarization filter that allows only one polarization direction of the transmitted light. The triple-reflector depolarizes the light upon reflection, in which case a portion of the light reflected back for reception passes through the second polarizing filter and can be recognized by the receiver. Reflective light barriers with polarizing filters can reliably detect even mirror-like surfaces in an advantageous manner.

The turning device arranged between the impression cylinder 1 for front side printing and the impression cylinder 2 for back side printing has a storage cylinder 3 and an inside-out cylinder 4 arranged adjacent to the storage cylinder 3. The storage cylinder 3 has approximately twice the diameter of the impression cylinders 1 and 2 and the inverted cylinder 4. The sheet turning area is advantageously a turning cylinder 4

During the rotation of the storage cylinder 3, the storage cylinder 3 firmly holds the leading edge of the sheet 5 by means of a gripper 7. After the trailing edge of the sheet 5 has reached the turning cylinder 4, the trailing edge of the sheet 5 is gripped by the gripper 8 of the turning cylinder 4 and is turned by the turning cylinder 4 rotating in the opposite direction to the storage cylinder 3. It is withdrawn from the storage cylinder 3, whereby the edge, which has been the trailing edge of the sheet 5, becomes the leading edge. From the reverse cylinder 4, whose printing surface is likewise located on the outside, the sheet 5 is delivered to a printing unit with an impression cylinder 2, on which the back side printing is performed.

Reference numerals 2 and 13 denote sensors each including a light receiver 13 and a light transmitter 12 and transmitting a light beam 15 from the light transmitter 12 to the light receiver 13. The light transmitter 12 and the light receiver 13 are turned upside down cylinder 4 and storage cylinder 3
It is attached between. Transmitter 12 is also receiver 13
Also, since the sheet 5 is located outside the transport area in which the sheet 5 moves, there is no risk of contact between the sheet 5 and the light receiver 13 or the light transmitter 12. Thus, the sheets can be transported without print stains due to abrasion.

In order to achieve this, the light transmitter 12 is oriented on the lower side of the sheet taking into account the sheet transport path from the storage cylinder 3 to the everting cylinder 4, and the light receiver 13 is positioned above this plane. Are located in It is likewise possible to arrange the light transmitter 12 and the light receiver 13 in reverse.
