Definitions
- Arc damage can also be caused by the return marks swinging back into the arc or caused by the located in the position at the feed table markers be, since the alignment of the next sheet already takes place when the end of the withdrawing sheet is still on the feed table.
- a sheet guiding device in a sheet-fed printing machine is known, implemented with the accelerated removal of the aligned sheet from the feed table becomes. This is between the transfer position, in which the transfer of one of the swinging position funded bow to one of these immediately downstream acceleration drum takes place, and a downstream of this drum pressure cylinder a sheet guiding device intended.
- the sheet guide consists of an air box and a sheet baffle, the distance to the jacket of the acceleration drum runs.
- the sheet guide plate is provided with blowing nozzles which follow the course of the sheet guide plate, realize blowing air flow directed away from the impression cylinder.
- the solution according to the invention advantageously allows a device to be used in the sheet system the subtending bow is guided so that on the one hand a touch with the gripper system of the swinging oscillation system or with the feed table swinging feed marks avoided, on the other hand the peeling bow against the jacket of the oscillating system downstream cylinder is pulled.
- FIG. 1 shows a sheet feeder of a printing press with a feed table 1, a Vibration system 2, a cylinder 3 and a pressure cylinder 4 shown.
- a feed table 1 In one at the feed table 1 working position is one of the front 5 and 6 brand existing Anlegmarke 7 shown.
- On the feed table 1 are an aligned sheet 8, a Following arc 9 and a detected by the oscillating system 2 subtractive sheet 10 is shown.
- the oscillating system 2 consists of a vibrator 11, which on a Schwingerwelle 12 stored and not shown means of a locking position on the feed table 1 via a Transfer position 20 (full line representation in Fig. 1) in a reversal position (dashed Representation in Fig. 1) and out of this back into the locking position on the feed table 1 is performed.
- the withdrawing sheet 10 to the gripper system 15 vibrates the vibrating system 2 in its reversing position, to subsequently swing back into the rest position at the feed table 1 to take over the sheet 8 to be aligned, while the withdrawing sheet 10 of the cylinder 3 is conveyed to the downstream pressure cylinder 4.
- the free end of the withdrawing sheet 10 from the gripper system 15 of the swinging back Vibration system 2 is touched. Since the Anlegmarken 7 to the feed table 1 for detecting the sheet to be aligned swing back 8, while the deducting Sheet 10 leaves the feed table 1, there is also the risk that the free end of the peeling Bow 10 is touched by the cover brands.
- the pneumatic sheet guiding device 21 is the of the rotating cylinder. 3 initiated wake flow, which is constantly air between the jacket 16 and the peeling Sheet 10 promotes, dissipated. At the same time, the side facing the jacket 16 becomes of the withdrawing sheet 10 caused Schleppströmung dissipated, so that in a through the jacket 16 and the jacket 16 facing side of the peeling sheet 10 formed joining wedge 31 forms a negative pressure. As a result of negative pressure the subtractive Arch 10 sucked against the jacket 16 of the cylinder.
- the pneumatic sheet guiding device 21 as a suction box 22 is the the cloak 16 adhering drag flow by means arranged in the edge 28 recesses 29 and the Schleppströmung adhering to the surface of the peeling sheet 10 removed by means provided in the lower plate 25 suction holes 27.
- the withdrawing sheets 10 are guided so that a contact by the gripper system 30th the swinging oscillation system 2 or by the oscillating to the feed table 1 Anlegmarken 7 is excluded.
