Definitions

  • the invention relates to a sheet application device for sheet processing and processing machines, in particular for sheet printing machines, with front marks periodically pivotable by a non-lockable cam mechanism and a locking device which can be controlled by a sheet control device and which holds the sheets on the system table when locked.
  • Sheet feeding devices are provided with a device for blocking the sheet feed in order to prevent the entry of sheets that do not fit properly or of double sheets into the machine, for example a printing machine. These locking devices become effective if a sheet control device detects a position that does not match or if the sheet is missing or the double sheet is being fed.
  • locking marks that can be held in place on the feed table are provided for blocking the sheet feed, which, as long as there is no blocking, perform periodic pivoting movements synchronously with the front marks.
  • the swivel movements are generated by a cam and a roller lever and transmitted to a branded drive shaft via a coupling gear.
  • Each front mark and each blocking mark is assigned a drive gear with a double rocker arm, which is rotatably mounted on the brand drive shaft and non-positively in one direction of rotation via a tension spring and in the other direction of rotation via an adjustable stop with a drive lever is bound, which is fixedly arranged on the brand drive shaft.
  • the periodic swiveling movement of the brand drive shaft is transmitted from the drive lever in the swiveling phase of the brands to the system table via the adjustable stop and in the swiveling phase from the tension spring to the double rocker arm, which is firmly connected to the brands via a coupling.
  • the double rocker of the locking marks additionally has a stop piece on a lever arm which, in the locked position, bears against a locking block of a locking lever combination which can be actuated by an electromagnet. If the sheet system does not fit, the sheet control device actuates the electromagnet, which causes the locking block to block the double rockers of the locking marks via the stop piece, thereby holding the locking marks on the feed table.
  • the invention has for its object to provide a sheet feeder of the type mentioned, which is characterized by simple structure and great reliability and which is suitable for high machine speeds.
  • this object is achieved in that the pivoting movement is transmitted only by rigid members of the cam mechanism in the pivoting phase of the front brands and that
  • Locking device is formed by catch hooks which are moved into a catching position on the system table by a control device independent of the cam mechanism when the sheet control device is blocked.
  • a Bo genanlegevorraum is created in which the movement of the front brands is completely independent of the movement of the catch hook of the locking device. This creates the possibility to design the drive of the front brands so that only low spring forces are required even at high machine speeds, since the highest accelerations that occur in the pivoting phase of the front brands do not have to be transmitted with the help of spring forces.
  • the front mark drive can be designed in the form of a positive control in the sheet application device according to the invention, which permits high accelerations and thus high machine speeds.
  • the invention also prevents parts of the drive device of the brands from being blocked, impact loads and resulting interference vibrations are largely avoided.
  • the drive of the locking hooks which do not have to fulfill a brand function, can be simple and relatively light, so that no significant inertia forces occur when the locking hook is actuated, and no interference vibrations are caused. It is also advantageous that the sheet feed device can be actuated at any time, since the pivoting of the catch hooks out of the blocking position is independent of the particular machine position.
  • hen hen that the catch hooks pivotally mounted on the system table are movable by pneumatic short-stroke cylinders from their pivoting position into the catch position, the short-stroke cylinders being controllable by an electro-pneumatic quick-closing solenoid valve.
  • the sheets coming from a sheet feeder are brought up to front marks 2.
  • the front brands 2 are fastened on a front brand drive shaft 3, which is mounted below the system table 1 and can be rotated via a drive lever 4.
  • the drawing shows the front marks 2 in the sheet alignment position, in which they are pressed 5 by train springs. Stops (not shown) ensure precise positioning of the front marks 2.
  • the swung-away position of the front marks 2 is indicated by dash-dotted lines.
  • the drive lever 4 is connected by a coupling rod 6 to a double-armed roller lever 7 which is pivotally mounted on an axis 8 fixed to the frame.
  • a pressure spring 9 By means of a pressure spring 9, the roller lever 7 with the roller 10 mounted at its free end is pressed against a front mark control cam 11, which is driven synchronously with the machine connected to the sheet application device.
  • the direction of rotation of the control cam 11 is indicated in the drawing by an arrow 12.
  • the swiveling of the front marks 2 takes place through the sector a of the control cam 11, the roller lever 7 being under tension the pressure spring 9 is moved to the dot-dash position.
  • the high acceleration forces that occur are transmitted directly from the control cam 11 via the roller 10 to the roller lever 7 and are forwarded by this via the coupling rod 6 and the drive lever 7 to the front marker drive shaft 3. It is therefore only in the pivoting phase of the front brands 2 rigid members of the front brand drive effective.
  • the spring force of the pressure spring 9 can remain comparatively low, since for the pivoting phase he has a considerably larger angle of rotation of the control cam and thus a considerably larger period of time is available.
  • the device for blocking the sheet feed consists of catch hooks 13 which are attached to a shaft 14.
  • the shaft 14 is mounted below the system table 1 in bearings 15 and is pivoted via a fork lever 16 which can be pivoted by a pneumatic short-stroke cylinder 17 which is also attached to the system table 1.
  • the short-stroke cylinder 17 contains a compression spring 18 which strives to move the piston of the cylinder into a basic position in which the catch hooks 13 are pivoted out of their catch position. This basic position is shown in the drawing with dash-dotted lines.
  • the short-stroke cylinder 17 is controlled by an electro-pneumatic quick-closing solenoid valve 19, which is controlled electrically by a sheet control device and is switched to a position in which the short-stroke cylinder 17 with a Compressed air shaft connects.
  • the thus actuated piston of the short-stroke cylinder 17 ver pivots via the fork lever 16, the shaft 14, whereby the catch hook 13 get into the catch position and block the sheet feed to the machine. If there is again a fitting sheet on the front marks 2, the sheet control device switches the quick-closing solenoid valve 19 back into its starting position, thereby relieving the piston of the short-stroke cylinder 17 and the catch hooks 13 are pivoted away.
  • the catch position for machine run is decoupled via the manual signal "paper run”.
