Definitions

  • the invention relates to a device for quality control of a sheet-fed printing machine according to the preamble of claim 1.
  • Sheet-fed offset printing presses are often associated with control or tuning desks, on which a test sheet can be placed and visually inspected.
  • These consoles usually have a surface inclined relative to the horizontal, so that a test sheet applied thereto can be inspected by an operator.
  • Abstimmpulte are usually assigned to the control station of the machine and are located near the boom. A sample sheet taken from the display can thus be placed directly on the desk and examined.
  • the console may additionally be associated controls for the remote adjustment of various devices of the printing press, in particular the Farbzonenfernver ein. If the test sheet is placed on the desk by, for example, adjustable stops corresponding to the zonal arrangement, then the operator can directly carry out the changes in color to be made in the respective ink metering zones.
  • a device for controlling an offset printing machine wherein the boom is associated with a switchable in an operating and a parking position control panel.
  • This control panel comprises means for remote control, in particular for the zonal remote color control.
  • the control panel In the working position, the control panel has a height that corresponds approximately to the top of the delivery pile. If the control panel is no longer needed, it is folded down and is seen in the direction of sheet travel behind the delivery pile.
  • a disadvantage of this known device that the accessibility is affected to the delivery pile.
  • small-format sheetfed offset presses which are mainly printed on limited editions, the delivery stack and thus the entire boom on a large amount, so that arranged in this way control panel can not be arranged in a ergonomically favorable height as Probebogenablage.
  • a sheet-fed offset printing machine with chain delivery and a control panel wherein the control panel is mounted with a support for sample sheet directly in sheet travel direction behind the delivery pile.
  • the sheets to be inspected can be placed directly on the top of the desk.
  • the console also has remote adjustment devices, especially for color zone remote adjustment.
  • the disadvantage here is that accessibility to the delivery stack is affected as in the aforementioned device.
  • the delivery pile can no longer be changed in the direction of the sheet transport. Also increases the length of the machine by this arrangement.
  • a printing machine with a station for inspecting sheets is known.
  • the printing press has in its sheet delivery in the area of a sheet conveying chain conveyor on a storage chamber for sample sheet.
  • a control test sheet interpretable by means of the chain conveyor are triggered by a control test sheet interpretable by means of the chain conveyor.
  • the operator may order a sample sheet to be inspected from the storage chamber Remove and place on a Abmusterungstisch above the sheet delivery. From this position actuators can also be reached at one or more printing units of the printing machine. The sampling of the sample sheet is carried out in the rearward position of the operating staff to the printing units.
  • Object of the present invention is therefore to develop a device for quality control of a sheet-fed press according to the preamble of claim 1 such that at low construction cost an ergonomically favorable option for sheet inspection is present.
  • a surface for receiving it can be deposited bow is attached above the delivery pile in a conveniently visible by an average sized operator height.
  • the surface in the form of a base has a size, so that even the largest processable on the machine sheet format can be placed.
  • the surface has an inclination relative to the horizontal, wherein the inclination angle is preferably between 30 ° and 45 °.
  • these support surface stops or a stop rail are mounted on the bottom, so that an applied bow can be aligned with this stop rail.
  • this surface is assigned at least one further adjustable stop means, so that the sheet placed on the support surface can be aligned in accordance with its format with respect to the zonal ink dosage.
  • This embodiment of the invention is preferably selected when devices for the zonal color zone remote adjustment are attached to the underside of the support surface for the sample sheets. An operator can then, after a sample sheet was removed in the boom below the support surface and placed on the support surface, the color control and correct by targeted intervention in the appropriate Farbdosierzonen.
  • the arranged above the delivery pile preferably inclined to the viewer extending support surface associated with a lighting device through which there is a glare and reflection-free assessment of the filed sheet.
  • the present invention makes it possible, especially in so-called low-pile jibs (low pile height jibs), to provide a simple and convenient way to examine test sheets.
  • the bearing surface mounted above the delivery stack is preferably arranged at a height of about 1 m above the bottom and preferably at an angle between 30 ° and 45 ° relative to the horizontal. An average-sized operator can thus easily remove an incoming below the support surface in the delivery sheet as a sample sheet and place it on the support surface.
  • By aligning the sheet format on the support surface adjustable alignment of the sample sheet is aligned according to the Farbdosierzonen within the machine.
  • the support surface in addition to the preferably provided controls for color ink remote adjustment associated with further control and display elements, then almost the entire printing process can be monitored and controlled from the boom.
  • electrical and / or mechanical components of the machine or ancillary equipment can be accommodated in the space thus located between the bearing surface and the chain system of the boom.
  • FIG. 1 shows the last printing unit of a sheet-fed printing machine 1.
  • a chain system 4 the printed sheets are removed from the impression cylinder of the last printing unit and placed on the top of a delivery stack 3 in the boom 2.
  • Sample sheet 11 Fig. 2
  • At the bottom of the inclined bearing surface 5 inclined relative to the horizontal controls 6 are preferably arranged in the form of pairs of keys, these controls 6 preferably serve the color remote adjustment.
  • the remotely adjustable elements of the ink metering 7 can be controlled in the individual printing units.
  • FIG. 1 shows the ink dosage 7 at the last printing unit.
  • FIG. 2 shows the arrangement according to FIG. 1 in a view from above.
  • the support surface 5 On both sides of the support surface 5 further controls 8, 9 are arranged, via which the printing press 1 and other remotely controlled running devices of the machine can be controlled.
  • the operating elements 8, 9 can also be associated with display elements, by means of which setting values can be displayed or menu-guided settings can be made.
  • the controls 6 for the individual Farbdosierzonen the paint metering 7 are mounted on the underside of the inclined support surface 5 and simultaneously serve as a stop for the deposited on the support surface 5 sample sheet 11.
  • the support surface 5 is associated with an adjustable alignment element 10 so that on the bearing surface 5 stored test sheet 11 can be assigned according to its format the metering zones of the machine. Thus, a staining determined and to be corrected at a specific point of the test sheet 11 can be directly assigned to the corresponding metering zone and corrected by actuating a pushbutton of the operating elements 6.
