Definitions
- the invention relates to a sheet guide system on a Printing machine according to the preamble of claim 1.
- DE 43 42 203 A1 proposes a Sheet feeding system of the type mentioned at the outset to design that from the upstream cylinder to the Transfer drum delivered sheets by a blowing device from above, i.e. in the direction of the sheet transfer, with air is applied.
- a hot air squeegee is used Drying the sheets assigned to the upstream cylinder. After handing over a sheet to the subordinate Cylinder is the arrangement of further for guiding the bow Air knife proposed.
- the suction openings become when turning the transfer drum cyclically closed by the transfer drum, when the two gripper systems are horizontal face each other.
- the arch always covers the largest Part of the suction openings.
- no continuous Air flow The moisture extracted from the bow accumulates in the air and remains within the Machine room.
- the air that is blown in is swirled with Moisture oversaturated and more randomly from the machine led out. Since there are no targeted material flows (air, Moisture, solvents, etc.) remain Drying result and sheet guiding of random factors dependent.
- the described sheet guide system is also very complex and requires a high energy input.
- the invention has for its object a simple designed sheet guiding system of the type mentioned to make available, in which through targeted material flows the sheet guide and - if drying between the printing units is provided - drying at reduced energy consumption is improved.
- the invention has the advantage that with little mechanical engineering the air of the aforementioned Blower is used several times. It serves first for Blowing of the cylinder guiding the downstream sheet passed bow, and after that this blowing air is in Steered towards the upstream bow-guiding cylinder, in order to achieve safe sheet guidance there too. In addition, the drag effect of the upstream bow-guiding cylinder used. After that, another part is used the blown air as carrier air for the guidance of the Conveyor drum conveyed sheet.
- the sheets are so carried with air relined that flutter movements prevented or at least the vibrations are strongly damped. This will do so achieved that the surface of the transfer drum and the sheet form a closed chamber in which the air compresses becomes. Therefore, one always works in the area of the sheet guiding system Force on the printed side of the sheet, creating a secure sheet guidance is achieved.
- a Counterflow area on the upstream sheet-guiding cylinder arises, which, if necessary, has a high drying effect having.
- the drier air is used as the arc air, which for safe sheet guidance in the area of Transfer drum ensures and at the same time the sheet continues dries.
- the arrangement of the blowing device can only dry air can be drawn in from outside the machine.
- the blowing device is expediently arranged in such a way that they counter to the direction of sheet travel in the direction of subordinate bow-guiding cylinder blows.
- it can be arranged on the air guiding element, it is further of advantage if they are concerned with their Alignment with the downstream sheet-guiding cylinder is adjustable. In this way, the blowing direction can be optimize depending on the printed fabrics.
- other arrangements of the Blow device conceivable. So you can also at the Arrange the transfer drum. In this case the blowing takes place in the machine cycle depending on the position of the Transfer drum instead.
- a further improvement of the bow guidance in the area of Transfer drum can be achieved in that along the movement path of the gripper rows in the lower one Area of the transfer drum a sheet guide from upstream to downstream arc-guiding cylinder extends.
- This sheet guide can be closed or essentially closed baffle become.
- the sheet guiding device it is also possible to use the sheet guiding device to be provided with air inlet openings in this way to achieve a levitation of the bow. This allows a touch of the guiding surface of the sheet guiding device through the bow even with difficult to handle Exclude substrates with certainty.
- An improvement in the bow guidance on the upstream sheet-guiding cylinder is achieved in that below of the air guiding element between the trajectory of the Rows of grippers and the upstream bow-guiding cylinder one oriented towards the latter Air guiding device is arranged. This can be done in parallel to the air-guiding sheet metal exist as Louvre grille or guide grille or as guide channels be trained. This makes it a non-vortex laminar Airflow is generated for a secure sheet support on the upstream sheet-guiding cylinder. Become the ends of horizontally running sheets of Air guiding device on the upstream bowing Cylinder-directed bends, so the Bow blowing further intensified. Such Angling can also be provided at the end of the air guiding element be what serves the same effect.
- a further intensification of the blowing on the upstream sheet-guiding cylinder can be achieved in that the Air outlet opening is designed as an air outlet duct.
- the air for the blowing is compressed further and the Area of air pollution of the upstream bow-guiding cylinder further enlarged.
- a dryer can be arranged in this air outlet duct, which intensifies the drying. He can be as Radiation dryer with ultraviolet or infrared radiation run or as a dryer, which with additional the air is blown dry, if necessary also warm air. Of course, you can also combine both combine.
- Air outlet and the air inlet for air circulation with each other are connected.
- sheet drying should also be achieved be, it is useful if between the air outlet and Air inlet Means for extracting air humidity are arranged.
- Such an arrangement should in particular when colors are processed which, in addition to moisture, are solvents contain which should not get into the work area.
- the better removal of the moist and feed as possible dry air is a training that provides that an air inlet leading to the blowing device in the Printing machine enters and one of the air outlet opening downstream air outlet leads out of the printing press.
- the air inlet and the air outlet can, for example through openings in a tread plate, preferably in the form of Lattices to be formed.
- Such a step plate as it does between the printing units of a multi-color printing press is arranged, can also serve as an air guide to serve.
- the air outlet is not into the work area, but is discharged to the outside.
- the Possibility of such controlled elimination of the Exhaust air is due to the enclosed space created by the Device is formed possible. It is a Another great advantage of the invention, because in this way the health conditions of the work rooms improved and the exhaust air can be sent for cleaning.
- the Sheet transfer area By using hot air to guide the sheet, the Sheet transfer area the function of a drying section take over, eliminating the use of an additional Drying plant, e.g. between two painting units can and a more compact design and thus can achieve associated cost savings.
- the air guide can be attached to the hinge Fasten the machine in such a way that it faces upwards can be folded away. In this way the transfer drum is good accessible. This is for better maintenance and cleaning the machine.
