Definitions
- the invention relates to a sheet guide device in the sheet line of printing presses a vibrating system, which has a feed table upstream of the vibrating system With the help of alignment marks aligned sheet and a revolving of the vibration system subordinate cylinder passes.
- the sheets are placed on an upstream feed table with the help of cover marks consisting of cover and front marks, which are within a work cycle from a position on the feed table to a position under the feed table and swing back to the feed table, aligned with the front edge.
- cover marks consisting of cover and front marks
- the vibration system is then decelerated and returned to the starting position returned at the feed table to take over the following sheet.
- the open grippers of the vibrating system touch the back of the pulling Sheet, causing damage to sensitive substrates and thus waste leads.
- the object of the invention is to provide a sheet guide device with which the pulling Bow is conveyed to the cylinder without damage and without fluttering to the Surface of the cylinder.
- the solution according to the invention advantageously enables that through a device in the bow system the pulling sheet is guided in such a way that there is contact on the one hand with the gripper system of the swinging vibrating system or with the at the feed table vibrating contact marks avoided, on the other hand the pulling sheet against the jacket of the cylinder downstream of the vibration system is pulled.
- FIG 1 is a sheet feeder of a printing press with a feed table 1, one 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 a front mark 5 and cover mark 6 existing Landing mark 7 shown.
- a sheet 8 On the feed table 1 are a sheet 8 to be aligned Subsequent sheet 9 and a pulling sheet 10 detected by the vibration system 2 are shown.
- the vibration system 2 consists of an oscillator 11, which is on an oscillator shaft 12 stored and by means not shown from a rest position on the feed table 1 via a Transfer position 20 (full line representation in Fig. 1) in a reverse position (dashed line Representation in Fig. 1) and out of this is led back to the locking position on the feed table 1.
- a gripper system 30 consisting of gripper fingers 13 and gripper cuffs 14 provided, which can be operated in a known manner.
- the vibration system 2 is arranged downstream of the cylinder 3, which also has a gripper system 15.
- the Cylinder 3 runs at a constant or alternating speed in the direction of rotation 19. In FIG. 1, in addition to the jacket 16 of the cylinder 3, the path 18 of the gripper arms 17 shown.
- pneumatic sheet guide device 21 In the direction of rotation 19 of the cylinder 3 in front of the transfer position 20 is one across the width of the cylinder 3 extending pneumatic sheet guide device 21 is provided.
- the pneumatic Sheet guiding device 21 is designed as a suction box 22, which is connected to vacuum generators 23 is provided, trained.
- the suction box 22 has an upper plate facing the cylinder 3 24 and a lower plate 25 facing the vibration system 2.
- the lower plate 25 runs approximately as an equidistant to the path 26 of the gripper cuffs 14 and has suction bores 27 provided.
- the top plate 24 approaches the jacket 16 of the cylinder 3, without touching it and forms an edge 28 with the lower plate 25 in the region of the edge 28 are recesses 29 at a distance from each other for the passage of the gripper Gripper system 15 is provided, the recesses 29 simultaneously connecting to produce the suction box 22 and serve as suction openings.
- the vibrating system 2 swings in their reversing position in order to subsequently swing back into the resting position on the feed table 1 to take over the sheet 8 to be aligned, while the pulling sheet 10 from the cylinder 3 to the downstream pressure cylinder 4 is promoted.
- the free end of the withdrawing sheet 10 from the gripper system 15 of the swinging back Vibration system 2 is touched. Since the feed marks 7 on the feed table 1 swing back to grasp the sheet to be aligned 8 while the pulling Sheet 10 leaves the feed table 1, there is also a risk that the free end of the pulling Sheet 10 is touched by the cover marks.
- the pneumatic sheet guiding device 21 causes the rotating cylinder 3 initiated drag flow, the constant air between the jacket 16 and the withdrawing Sheet 10 promotes, dissipated.
- the side facing the jacket 16 of the pulling sheet 10 caused drag flow dissipated, so that in one through the jacket 16 and the side of the peeling sheet facing the jacket 16 10 formed wedge 31 forms a negative pressure.
- the pulling Bow 10 sucked against the jacket 16 of the cylinder.
- the pneumatic sheet guiding device 21 When the pneumatic sheet guiding device 21 is designed as a suction box 22, the trailing flow adhering to the jacket 16 by means of the recesses arranged in the edge 28 29 and the drag flow adhering to the surface of the pulling sheet 10 removed by means of the suction holes 27 provided in the lower plate 25.
- the suction holes 27 provided in the lower plate 25.
- the suction box 22 is height-adjustable by means not shown, and with respect to it Position to the jacket 16 of the cylinder 3 adjustable.
- the prevailing in the suction box 22 The vacuum is adjustable. It is also possible to depend on the negative pressure the material to be processed and the individual operating conditions to make it trackable or to set it above preset values.
