Definitions
- the invention relates to one between the last printing or finishing unit of a printing press and one
- Pressure delivery device arranged for dusting printed sheets, with one or more powder blowing nozzles on the sheet and a conveying cylinder with which the sheet to be dusted is moved past the nozzles.
- a device of this type is known for example from DE 196 09 438 AI.
- the printed sheet is delivered from the last printing unit of the printing press to an endless conveyor, the grippers of which are attached to rotating chains.
- This endless conveyor is located in a sheet delivery device in which the sheets are stacked to form a sheet stack.
- the sheets are previously dusted with powder, for which the endless conveyor transfers the freshly printed sheet to a conveying cylinder, on which the sheet is dusted with powder by means of the nozzles. After the pollination process, the sheet is again taken over and stacked by an endless conveyor.
- the main advantage of this device is that the sheet is not dusted on the chain conveyor with its high-build gripper bar but on a feed cylinder, and therefore the nozzles can be mounted at a short distance from the sheet surface.
- the grippers holding the bow are almost Completely recessed in the feed cylinder and only slightly protrude beyond the sheet surface.
- the device has the significant disadvantage that the sheet has to be gripped several times and two endless conveyors have to be provided.
- the invention has for its object to provide a device that has a less complex structure and with which the sheet can still be dusted optimally.
- This object is achieved with a device having the features of the preamble, in which the feed cylinder is arranged immediately after the printing or finishing unit in such a way that the sheet is taken over directly by the printing or finishing unit.
- the freshly printed sheet is transferred directly from the last station of the printing press, which can be either a printing unit or a finishing unit, for example a coating unit, a punching, creasing or perforating unit or the like, to the feed cylinder without en endless conveyor, for example a chain conveyor or the like, is interposed.
- the powder-blowing nozzles can be arranged in the immediate vicinity of the surface of the freshly printed sheet, since there are no disruptive, high-rise grabs.
- the carryover of stray powder into the last station of the printing press is low, since dust is not directly dusted on the last cylinder of the last station.
- the device according to the invention is considerably shorter, since the endless conveyor usually present between the printing unit and the delivery cylinder can be dispensed with.
- the printing or finishing unit has a transport cylinder and the feed cylinder is arranged directly after this transport cylinder. The transfer takes place between two cylinders, so that the gripper technology available in the printing press technology for gripping and transporting printed sheets can be adopted.
- the axes of the transport cylinder and the feed cylinder advantageously lie essentially in a horizontal plane or this plane is only slightly inclined. This has the essential advantage that the powder-blowing nozzles are provided in an upper region of the feed cylinder and do not have to be arranged on the side of the feed cylinder, as in the prior art. On the one hand, there is accessibility in the event of a repair or replacement much easier, on the other hand, there is more space for the entire dusting unit.
- Optimal integration of the unit according to the invention into the printing press is achieved in that it is controlled by the printing or finishing unit or the printing press.
- the drive is also carried out directly or via a separate drive motor, which is regulated by the printing press.
- the feed cylinder has at least one receiving space for sheet grippers running in the longitudinal direction thereof, so that the individual grippers only slightly protrude beyond the detected sheet.
- the receiving space is largely closed with a cover element. This prevents the powder blown onto the sheet from being whirled up and carried away in the direction of the printing or finishing unit.
- the sheet runs more smoothly and the sheet fits better against the feed cylinder.
- the advantage is achieved that excess powder can be suctioned off from the surface of the feed cylinder substantially more effectively, since this is less jagged and powder can no longer accumulate in depressions or openings.
- the curvature of the cover element advantageously corresponds to the curvature of the jacket of the feed cylinder.
- the cover element is, for example, a curved shell segment which is provided with slots through which the grippers can pass.
- This cover element can be made of plastic or metal (cover plate) and can be placed over the receiving space and closes it flush with the jacket of the feed cylinder. The cover element follows the course of the jacket of the feed cylinder so that no eddies are created.
- the powder-blowing nozzles are arranged behind a slit diaphragm, which opens when a sheet to be dusted is present.
- a slit diaphragm which opens when a sheet to be dusted is present.
- the path between the nozzles and the surface of the delivery cylinder is only free if a sheet to be dusted is present.
- the slit diaphragm closes so that excess powder is retained and can be suctioned off.
- the slit diaphragm is located in the immediate vicinity of the sheet surface.
- the drawing shows a cross section through the device according to the invention, wherein the printing machine is only indicated and only a part of the sheet delivery device can be seen.
- FIG. 10 shows the schematically illustrated last printing unit of a printing press 12, in which a printing sheet 14, which is only shown schematically, has been delivered by a printing cylinder 16 to a transport cylinder 18, so that it is supplied by a delivery cylinder 20 of a device for dusting printing sheets, which is designated overall by 22 14 can be adopted.
- grippers 24 are provided, which only slightly overlap the lateral surface 26 of the feed cylinder 20.
- the jacket surface 26 forms the contact surface for the printed sheet 14.
- the arrows 28, 30 and 32 indicate the directions of rotation of the cylinders 16, 18 and 20, whereas the arrow 34 indicates the direction of transport of a chain conveyor 36.
- the angle of inclination of the plane 50 can be between 0 ° and ⁇ 20 °. Because of this orientation of the feed cylinder 20, there is sufficient free space above the feed cylinder 20 so that the pollination unit 38 can be arranged there. This dusting unit 38 is easily accessible from above.
- the feed cylinder 20 has a diameter so that it can be provided with grippers 24 on opposite sides and can take up two printing sheets 14 with these grippers with one revolution.
- the grippers 24 are attached to a gripper shaft 52, which in turn is arranged in a receiving space 54.
- This receiving space 54 is overlapped by a cover element 56, which is a shaped sheet, for example.
- the curvature of the cover element 56 is selected such that the outside thereof is continuously in the Shell surface 26 merges.
- the cover element 56 has only slots which are gripped by the grippers 24.
- the cover element 56 can, for example, be unscrewed and removed for maintenance purposes.
