A method and a device for ejecting a defective sheet at a feeder of a processing machine, in particular a sheet-fed rotary printing machine, include a transporting device, which can be regulated independently of machine operation, for transporting a sheet identified as a defective sheet with deceleration in such a way that gripper devices of a cylinder cannot grip the sheet and the sheet is transported to a depositing location by the transporting device and a guide. A feeder of a sheet-fed rotary printing machine having an ejecting device, is also provided.
Description
- This application claims the priority, under 35 U.S.C. §119, of German
Patent Application DE 10 2008 048 407.5, filed Sep. 23, 2008; the prior application is herewith incorporated by reference in its entirety. - The invention relates to a method and a device for ejecting defective sheets at a feeder of a processing machine, in particular a sheet-fed rotary printing machine. The invention also relates to a feeder in a sheet-fed rotary printing machine having the ejecting device.
- The detection of defective sheets at the feeder of a processing machine gives rise to the problem that the machine has to be stopped in order for a sheet identified as a defective sheet not to be conveyed into the machine. An appropriate method is disclosed in German Published, Non-Prosecuted Patent Application DE 101 05 991 A1.
- A device for ejecting a sheet at the delivery is described, for example, by German Published, Non-Prosecuted
Patent Application DE 10 2005 004 881A1. In that case, a deflecting device is pivoted into an interspace between two grippers of a sheet-transporting chain-gripper system. - It is accordingly an object of the invention to provide a method and a device for ejecting defective sheets and a feeder having the ejecting device, which overcome the hereinafore-mentioned disadvantages of the heretofore-known methods and devices of this general type and which can be used at a feeder of a processing machine.
- With the foregoing and other objects in view there is provided, in accordance with the invention, a method for ejecting a defective sheet. The method comprises providing a processing machine with a feeder at which the defective sheet is to be ejected, a sensor for sensing defective sheets, a cylinder, gripper devices, and a transporting station for feeding a sheet to the cylinder. A sheet identified as a defective sheet is transported through the transporting station with deceleration and the sheet is transported further without the defective sheet being received by the gripper devices.
- With the objects of the invention in view, there is also provided, in a processing machine having a feeder, a cylinder and a machine drive, a device for ejecting a defective sheet at the feeder. The device comprises a transporting station for feeding sheets to the cylinder. The transporting station has a drive to be regulated in time, cycle or sequence with the processing machine, but independently of the machine drive.
- In accordance with another particularly advantageous feature of the invention, the sheets identified as defective sheets are not fed to the processing machine and stoppage of the processing machine is avoided at the same time. In a particularly advantageous manner, it is provided that blanket cylinders disposed in the printing units are disconnected one after the other from the impression cylinder in accordance with the arrival of the ejected defective sheet.
- In accordance with a further feature of the invention, the transporting device for feeding the sheets to the feed cylinder is advantageously constructed as a suction belt. As a result of this measure, the transporting device also serves for transporting the sheet during the ejecting operation. The ejecting device is formed by a curved directing plate on which the defective sheet is guided to a depositing location in part by the motive power of the suction belt and in part by the gravitational force acting on the sheet.
- In accordance with a concomitant advantageous feature of the invention, transporting rollers, which can be driven in opposite directions, grip the sheet securely and transport it away to be disposed in an ejecting path.
- Other features which are considered as characteristic for the invention are set forth in the appended claims.
- Although the invention is illustrated and described herein as embodied in a method and a device for ejecting defective sheets at a feeder of a processing machine and a feeder having the ejecting device, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
- The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

FIG. 1 thereof, there is seen a machine forprocessing sheets 7, e.g. aprinting machine 1, which has afeeder 2, at least oneprinting unit delivery 6. Thesheets 7 are removed from asheet stack 8 and fed separately or in imbricated form, over a feed table 9, to a sheet-feeding device 27, which transfers thesheets 7 with acceleration to theprinting units plate cylinder 11, 12, in a known manner. Theplate cylinders 11 and 12 each have adevice plate cylinder 11, 12 is assigned adevice - The
sheet stack 8 rests on astacking panel 10 which can be raised in a controlled manner. Thesheets 7 are removed from the top side of thesheet stack 8 through the use of a so-calledsuction head 18 which has, inter alia, a number of lifting and pullingsuckers sheets 7. Also provided are blowing devices 22 for loosening the top sheet layers and follower elements 23 for stack adjustment. A number of lateral andrear stops 24 are provided in order to align thesheet stack 8, in particular thetop sheets 7 of thesheet stack 8. - The sheet-
feeding device 27 is constructed as a second transporting station disposed downstream of the feed table 9, which is constructed as a so-called “suction-belt table,” as seen in a sheet-transporting direction. Thissecond transporting station 27 accelerates thesheet 7 before the latter is gripped by agripper device 28 of acylinder 26, e.g. a feed cylinder. Thetransporting station 27 may, for example, be a pre-gripper or a gripper device which is driven in linear fashion. - In the exemplary embodiment according to
FIG. 2 , thetransporting station 27 is constructed as a suction-belt table. The latter has at least onetransporting belt 29 circulating endlessly over deflectingrollers roller 32 being driven through the use of adrive motor 33. Asensor 34 for sensing defective sheets, which is disposed on the feed table 9 or on thetransporting station 27, interacts with thedrive motor 33 through the use of acontrol computer 36. - During routine operation of the machine, the respectively
front sheet 7 of a sheet stream conveyed over the feed table 9 is gripped by thetransporting station 27 and accelerated to machine speed or the speed of thefeed cylinder 26. Thegripper device 28 of thefeed cylinder 26 grips thesheet 7 at its leading edge and transports it to adownstream cylinder 37, e.g. to an impression cylinder of theprinting machine 1. - Beneath the
feed cylinder 26, but above a feed plane E formed by the feed table 9 and thesecond transporting station 27, a preferablystationary directing device 38, e.g. a curved directing plate, of an ejecting device, is provided downstream of the location at which the leading sheet edge is transferred to thegripper device 28. This directing plate intersects the plane E and forms a guide for an ejectedsheet 7 a, with the guide terminating in a depositinglocation 39. - In the case of the exemplary embodiment according to
FIG. 3 , a sheet-transporting device including two interactingtransporting rollers directing plate 38 and the plane E. - When a
defective sheet 7 a is sensed by thesensor 34, thecontrol computer 26 generates a signal which causes thetransporting station 27 to accelerate thesheet 7 a, or if necessary to brake it, only to the extent where, rather than it being gripped cyclically by thegripper device 28, it is transported further through thetransporting station 27 on the plane E. In the case of the preferred exemplary embodiment according toFIG. 2 , thesheet 7 a is ejected into the depositinglocation 39 by thedirecting device 38. In the case of the exemplary embodiment according toFIG. 3 , the leading edge of thesheet 7 which is to be ejected passes into a nip formed by the transportingrollers transporting rollers - A further method step involves blanket cylinders being disengaged from their respective impression cylinders at a point in time at which the
defective sheet 7 a would have passed through the respective nip between the blanket cylinder and impression cylinder, in order to ensure that the application of ink on the blanket cylinder which was intended for thesheet 7 a does not soil the impression cylinder.
