Definitions
- the invention relates to a sheet processing machine with a turning device, a method for conveying sheets in particular in a turning device of a sheet processing machine and the use of a sheet guide element containing a deionization device in a sheet processing machine, in particular a turning device of a sheet processing machine.
- a device for removing electrical charges from flat material is known from EP 1 155 834 A2, the positive charge of a print carrier lying on a metal plate being compensated for by means of first ionizer tips. Due to the remaining negative charge on the underside of the print carrier, the latter rests with the discharged surface on another metal plate, the negative charge being compensated by the downstream ionization rod.
- This complex arrangement is not suitable for sheet guiding elements in sheet processing machines, in particular in turning devices of sheet processing machines.
- a device for electrostatically influencing signatures is known from DE 197 55 745 A1, a flat charging electrode being applied to the guide surface of a sheet guide plate.
- the device is intended to pull the sheets onto the sheet guide plate by an attractive effect and by blowing air in one To be kept levitated.
- a stable floating height of the arches cannot be kept constant by such a device.
- the flat contact electrode interferes with the nozzle distribution, which must be designed according to the need for arch support.
- a fan unit in a printing press which comprises controllable ion fans.
- a printing substrate sheet can be guided and turned by means of a generated negative pressure on the turning drum.
- fan units containing ionic fans can be arranged within a cylinder or integrated into its surface. This is complex and also not sufficiently effective.
- a device for turning a sheet while it is being conveyed through a printing press is known, a brake arrangement for a sheet being fixed to the frame.
- the braking arrangement consists of a generator for an alternating magnetic field and a pneumatic guide device for the sheet.
- a current should be induced in the ferromagnetic material of the sheet or the printing ink on the sheet.
- a magnetic field emanating from the eddy current is intended to counteract the field of the generator so that the arc is braked.
- the effect of this principle is questionable.
- the arcs are also not discharged because no ions are emitted by the generator.
- a turning device of a sheet-fed printing machine is known, the sheet transport path on or in connection with a storage drum being assigned an ionization device, whereby the sheets guided on the storage drum or those fed to the storage drum can be charged with electrical charges.
- the invention is based on the object of creating an alternative sheet processing machine or an alternative method for conveying sheets in a sheet processing machine or to improve sheet guidance in general in a sheet processing machine, in particular a turning device of a sheet processing machine.
- reliable sheet guidance is to be improved, especially in the area of a turning device, especially with low grammage or film sheets.
- the invention has the advantage that an alternative sheet processing machine or an alternative method for conveying sheets in a sheet processing machine is created.
- the sheet guidance is further improved precisely in the area of a turning device, which can advantageously lead to a significant increase in the performance of a sheet-processing machine, for example a sheet-fed printing machine, in particular a sheet-fed offset printing machine.
- Deionization of a sheet can particularly preferably be achieved after the sheet has been detached from a sheet guide cylinder, in particular a storage drum, in a turning device.
- the machine can be suitable or equipped for processing sheets of low grammage and / or for processing foil sheets.
- the machine can process sheet material with a grammage of more than 250 g / m 2 , but preferably less than 250 g / m 2 , particularly preferably less than 150 g / m 2 and very particularly preferably less than 80 g / m 2 , in particular printed and / or painted.
- One, two or even more discharge electrodes can preferably be arranged in the area of the sheet guide element, in particular a sheet guide plate of a turning device. The arrangement can take place as a cassette.
- one or more discharge electrodes can be placed on the sheet guide plate, or one or more discharge electrodes can be embedded in the sheet guide plate.
- electrodes that are let in are preferably each positioned between insulators, the surfaces of which in particular terminate tangentially on the sheet guide plate.
- the sheet guide element in particular the sheet guide plate, preferably delimits the long side of a turning area of a turning device downwards.
- the sheet guide element, in particular the sheet guide plate, is preferably spaced from the cylinder tangent between a storage drum and a turning drum in such a way that the distance to the sheet corresponds to the optimal electrode spacing.
- a device in particular a suction cup on the storage drum, can be provided which also spans or tightens the sheet in the vicinity of the cylinder tangent between the storage drum and turning drum, so that not only the optimal electrode spacing is maintained over the entire sheet length, but also the influence there can be carried out on the arc, where it remains free of ion-binding contact with mass-laden machine parts on the top and bottom, so that the ions can pass into the activated deionizing ambient air with little hindrance, which ultimately leads to the maximum possible discharge of the arc.
- a discharge cassette is preferably introduced into the sheet guide element, in particular sheet guide plate under the turn for discharging the sheets.
- a discharged sheet is freed from the effects of electrostatic forces and can be smoothed so that it can pass a subsequent processing station or printing zone without waves and without wrinkles.
- it makes sense to provide deionization devices in addition to the deionization device in the turn in further or preferably all printing units and possibly further plants and / or a display, since the printing material always is recharged in a pressure zone.
- sheet guide elements which are designed as sheet guide plates and contain deionization devices are preferably used which, at a suitable distance from the sheet conveying path, particularly advantageously ensure optimum discharge and guidance of the printing materials at the same time.

- the sheets are preferably pressed against the lateral surface of the printing cylinder 5 in small press gaps by support elements arranged on brackets.
- the support elements can be elastic Have surfaces.
- Such disks are preferably also made twice as large and can preferably have recesses for the rotating gripper carriages of the chain conveyor system.
- Fig. 10 shows a last sheet guide cylinder, in particular printing cylinder 5, of the machine 1 with a downstream chain wheel 18 of the chain wheel shaft and sheet guide element arranged below the chain wheel shaft, in particular a sheet guide plate 9 described above. Between the axis of rotation of the chain wheel 18 and the axis of rotation of the printing cylinder 5 is a Connection line drawn on which the transfer center is located in the transfer area.
- the sheet guide plate 9 is arranged below the sprocket shaft and has, in particular, metallic comb fingers 10 in the area facing the printing cylinder 5, in particular as already described for the printing unit 2.
- the sheet guide plate 9 is preferably further spaced from the axis of rotation of the sprocket shaft or of the chain wheel 18 than the areas of the sheet guide plate 9 adjoining in the sheet conveying direction BFR.
- the comb fingers 10 can, for example, be spaced a few millimeters apart. for example between 1 and 10 mm, preferably between 2 mm and 3 mm, to the lateral surface of the printing cylinder 5.
- the sheet guide plate 9 in the delivery 4 is constructed at least approximately identical to the sheet guide plates 9 in the printing units 2 or units of the machine 1. In this way, the same favorable sheet guiding conditions are preferably ensured in the entire machine 1.
- FIG. 11 shows a sheet guide cylinder, in particular a printing cylinder 5, for example as described above, with a downstream sprocket shaft and a sheet guide element arranged below the sprocket shaft, in particular a sheet guide plate 9, as described above.
- the sheet guide plate 9 shown in a side view has a cover, in particular containing a non-conductive or non-metallic material described above or made of non-conductive or non-conductive material. non-metallic material existing cover part 13 on.
- the deionization device 8 can be removed, for example, from the sheet guide element, in particular the sheet guide plate 9.
- the deionization device 8 can, for example, be removed from below or between the chain wheels 18 of the chain wheel shaft.
- the deionization device 8 can, for example, be removed from the side and / or by displacing at least a part of the sheet guide plate 9.
- the cover in particular the cover part 13, closes the opening required by the deionization device 8.
- the cover is preferably dimensioned or attachable in such a way that a continuous or almost full-area sheet guide surface of the sheet guide plate 9 is created.
- the cover part 13 can be designed or arranged as already described above.
- a sheet conveying system in the turning device 3 and / or in a work or printing unit 2 in particular a turning drum 17 or sheet conveying drum 7 or a gripper carriage in the delivery 4, the sheets are transported by a sheet guide cylinder, in particular a storage drum 16 or a Impression cylinder 5, taken over and guided past a deionization device 8 along the sheet guide element, in particular the sheet guide plate 9, on the sheet conveying path.
- a device In the area of a transfer drum or a sprocket shaft, a device can be provided which additionally guides the sheet in the vicinity of the gripper impact path in a defined manner only at the edges so that the optimal electrode spacing is maintained over the entire sheet length and the sheet does not prematurely hit the sheet guide plate 9 touches and falls below said optimal electrode distance.
- the sheets are detached from the lateral surface of the sheet guide cylinder, in particular the printing cylinder 5, by the sheet guide element, in particular the sheet guide plate 9, preferably with a spiral shape.
- the comb fingers 10 of the separation loop of the sheet give way when it is pulled from the outer surface with a suitable distance. Allowing a minimal pull-off loop advantageously increases the detaching radial portion of the pull-off forces. Due to the arrangement of the Venturi nozzles along the guide contour of the sheet guide element in connection with the associated balanced floating height of the sheets under the gripper impact path, the suction forces of the air cushion can act on the sheet located on the regular sheet path. In this way, the bow is held on the outside of the radius of the gripper impact path and the detachment loop is kept small.
- the deionization device 8 provides positive and negative ions in order to be able to compensate for the changing charge states on the sheet surface.
- a deionization device 8 is used in particular in each printing unit 2 or unit of the machine 1 because the sheet, in particular the sheet of film, is extremely recharged during each printing process.
- the sheets are optimally discharged by the deionization device 8 of the or each printing unit 2, preferably each unit, the turning device 3 and / or the delivery 4.
- Unloading makes it possible to feed the sheet to the next conveyor system, for example a printing cylinder 5 or a gripper carriage, in a constantly floating manner without the sheet being scratched by contact with the sheet guide element, in particular a sheet guide plate 9.
- the one or more discharge electrodes 12 of a respective deionization device 8 ensure, in particular, an active discharge with both positive and negative ions.
- the generators provided preferably work in a range from 3 to 6 kV, optimally with a high voltage of at least approximately 4.5 kV. The high voltage can also be set depending on the determined electrostatic charge.
- a respective sheet is discharged, so that the deionized sheets, free from electrostatic forces, are smoothed and placed on the sheet guide plate 9 or the air cushion generated by the sheet guide plate 9.
- the sheets remain deformation and smear-free over the entire machine 1.
