Definitions

the invention relates to a method and a corresponding device for control the sheet feed in a sheet-processing printing machine according to the preamble of the process or device claim.
the sheets are made by the Top of a stack of feeders with suction and vacuum cleaners removed and then in shingled form on a conveyor table with in particular Suction belts transported to the system.
a conveyor table with in particular Suction belts transported to the system.
the movement of the Separating and drag vacs and the conveyor belts for transporting the sheets in shingled form takes place from the drive of the printing press, for which purpose Stopping the investor, i.e. its movement, the feeder via a switchable clutch is connected to the printing press.
the suction air is also the separating and Drag vacuum switchable, i.e. single sheets can still be stacked over the Feed the conveyor table into the machine while the sheet is already being removed from the stack is stopped.
DE 4 013 740 C2 describes a method and device for quickly reaching it of the production status in an offset printing press, in which before the Print operating position a pre-dampening and pre-inking of the plate cylinder and the Blanket cylinder is provided.
the printer has to be able to resume printing operation of such a stopper because of the shutdown of the feeder and the switching off of the separating and drag vacuums all sheets together with the stopper at the system from the conveyor table remove. Especially with very sensitive substrates, they can be removed damaged and are therefore no longer usable. Because between the pile of investors and the plant in the size order 4 to 7 sheets depending on the length of the Conveying table and the degree of scaling are particularly frequent Stopper represents a costly loss of substrate.
DE 43 33 071 C1 describes a method and device for controlling the Sheet inlet known when starting a sheet-processing printing machine. It the feeder is switched on and off in such a way that the sheet inlet is synchronized with Lifter, i.e. always with the same lifter position.
the object of the present invention is therefore a method and a device to develop in such a way according to the preamble of the respective claim, so that especially when restarting after a stop, the production pressure with a minimum number of waste sheets can be achieved.
this predetermined position is characterized in that of this Position from the number of machine revolutions until the first sheet is printed is known.
the program for the is started Pre-wet and pre-ink the plate cylinder and / or blanket cylinder in the first printing unit. Accordingly, the pre-moistening and Pre-inking programs started in the other printing units.
the mechanical The investor is switched on exactly when the intended number of Machine revolutions for the pre-wetting and pre-inking program reduced by the number which a first sheet from the standstill position of the Investor until the first printing unit has expired. It is thus achieved that the Paper feed into the press is always synchronized with the program flow of the Pre-moistening and pre-inking takes place.
the conveyor table in the sheet running direction in front of the system, in particular photoelectrically working preliminary query is arranged.
This is preferably in the conveyor table attached so that the third sheet in the scale does not yet reach it has if due to the first sheet in the scale on the system (stopper cause) the system is blocked and the investor is therefore shut down.
the printer then only needs the missing sheet and the two following sheets from the conveyor table to remove - it is assumed that this sheet because of the Stopping no longer taking correct dandruff position - then by renewed Switch on the feeder the sheet now lying first in the scale so far is funded until the preliminary inquiry determines its arrival.
the preliminary query has a double function, namely, on the one hand it can be determined by the preliminary query whether after a stopper the Printer the cause of the stop and the corresponding number of subsequent sheets removed from the conveyor table.
this preliminary query shows that when the sheet lying first in the scale then reaches the preliminary query, that is when the investor is to be shut down again.
the location of the preliminary query thus also defines the then triggered stopping of the investor from the predetermined position which the sheet run is started again when the intended program started to pre-wet and pre-ink the plate and / or blanket cylinder has been.
FIGS. 1 and 2 show the method according to the invention along with associated device using a previously indicated Preliminary inquiry.
the other figures show the method according to the invention, which manages without an additional preliminary inquiry in the funding table.
a sheet-fed offset printing machine In a sheet-fed offset printing machine according to FIG. 1 - the first printing unit is shown here a sheetfed offset press - the sheets are from the top of one Feeder stack 1 is lifted off by a separating and drag vacuum 2 and shingled Form transported on a conveyor table 3. Be conveyor belts, not shown then the sheet 4 transported over the conveyor table 3 to a system 6 and after a Transfer the alignment and control process (correct sheet feed) to a pre-gripper 7, whereupon the acceleration to the peripheral speed of the printing unit takes place.
the sheet 5 on the system 6 is created as faulty was determined, whereupon the locking of the system 6 and the pre-gripper 7 in addition the clutch 8 is switched between the printing press and the feeder.
the Suction air loading of the separating and drag vac 2 will continue maintained so that the sheet gripped by the separating and dragging 2 in his Position remains during the parking of the investor.
the conveyor table 3 is in Direction of conveyance of the sheets 4 in front of the system 6, in particular after one Photoelectric active principle working preliminary query 9 attached, which according to the in Figures 1 and 2 illustrated embodiment is such a distance before System 6 is located so that the front edge when the sheet 5 is in contact with the system 6 of the fourth sheet 4 in the scale has not yet reached the preliminary query 9.
a controller 11 which the switching of the suction air for the separating and drag vacuum 2, which also causes Locking / unlocking the system 6 and the pre-gripper 7 triggers the switching of the Clutch 8 performs and also monitors the signal of the preliminary query 9.
a system control and its connection to the control 11 is shown described operations to run a certain number of revolutions the control 11 additionally with an angle encoder 10 of a rotating one-speed Printing machine shaft connected. This is also done via the control 11 Trigger the intended programs for pre-moistening and pre-inking plates and / or Blanket cylinders.
the program for pre-wetting and pre-inking is envisaged n revolutions until a first sheet enters the printing zone 12 of the first Let the printing unit run, so after n - m turns the sheet run starting from the situation according to FIG. 2 by switching the clutch 8 again added.
m is the number of revolutions of a single-turn shaft Machine, which is the first sheet from the preliminary query 9 or the position which it has at the Disengaging the feeder has resumed until pressure zone 12 is reached has to travel in the first printing unit.
This number of m revolutions is determined here according to the design conditions of the printing press and the arrangement the preliminary query 9 at the conveyor table 3.
m is not an integer, and n> m also applies.
Figure 3 shows the same situation with regard to sheet travel as shown in Figure 1, wherein no preliminary query is provided in the conveyor table 3 here.
the separating and drag vacuums 2 remain here as well supplied with suction air, i.e. they hold the top sheet of the feeder stack 1 in the Position according to shutdown. The ones that previously entered the machine correctly Sheets are printed, after which the last sheet is printed consequent printing shutdown takes place.
the feeder is on the Coupling 8 switched on until the first sheet from the scale again the system 6 has reached. The determination is made via the system control, not shown. The feeder is then disengaged while still using suction air acted separating and drag vac 2 ( Figure 5). Now with decoupled investors the intended program for pre-moistening and pre-inking the cylinders in particular of the first printing unit started. Here too it is assumed that for this Program sequence n revolutions are provided. After n - m revolutions (n> m) the feeder is switched on via the clutch 8, whereupon the first at the system 6 correctly fitting sheet is detected by the pre-gripper 7.
m the number of one-turn machine revolutions that the sheet from plant 6 to has to travel to printing zone 12 in the first printing unit. Furthermore, this is directed Number of revolutions m according to the design conditions of the printing press, So in the end, the path related to a single-tour wave from Appendix 6 to the one mentioned Print zone 12.
