Definitions

  • the invention relates to a device for monitoring the registration of a printing plate on the plate cylinder of printing machines in accordance with the preamble of claim 1.
  • the printing plates for the differently colored partial images are each mounted on a plate cylinder.
  • Each printing plate is fastened (clamped) with an edge assigned to the start of printing in a clamping rail and then placed around the outer circumference of the cylinder until its rear edge, which is assigned to the printing end, can in turn be fastened in a clamping rail.
  • the pressure plate is then tensioned.
  • the individual printing plates must be very carefully, i.e. be inserted in register with their respective front edge in the corresponding pressure start clamping rail.
  • the pressure plates often have recesses in the form of punched-outs on the edge assigned to the start of printing, which cooperate with corresponding dowel pins in the tensioning rails.
  • a device for checking the register-accurate clamping of printing plates in which feeler pins are arranged in the pressure start clamping rail which the register-correct position of the printing plate can be determined by touching the printing plate edge with the feeler pins.
  • This previously known device provides in particular a display device arranged inside the cylinder pit, by means of which the pressure plate to be adjusted via an adjustable front tensioning rail can be specifically adjusted.
  • a device with a similar effect in which blocks which are electrically insulated from the pressure cylinder are provided as stop probes and which cooperate with corresponding punchings in the pressure plate.
  • DD 69 382 PS discloses dowel pins which are electrically insulated from the plate cylinder and which, when they come into contact with the pressure plate or an edge of the pressure plate, result in an electrically closed contact.
  • This closed electrical contact in this way can be queried by the printing press control system via a measured value transmitter.
  • a measured value transmitter for example consisting of a slip ring and current collector, must be provided, which results in additional susceptibility to faults.
  • a device for automatically changing printing plates in which the above-mentioned measuring arrangement could be used, is known from DE 39 40 796 C2.
  • a printing plate from a Storage chamber inserted into a clamping rail of a plate cylinder via transport rollers, for which purpose this was previously moved into a specific angular position.
  • a position detector not specified in this document determines whether the pressure plate is correctly positioned within the tensioning rail assigned to the start of printing, whereupon, if this is the case, the devices for closing the tensioning rail (clamp) are actuated.
  • a device which can be referred to as a printing plate insertion aid, for feeding printing plates into the printing start clamping rail, in which a type of system table is placed on the correspondingly positioned plate cylinder, is known from JP-A 62-22 1541.
  • This system table has pivotable dowel pins, which interact with corresponding punched-out areas of the pressure plate. If these are swiveled away from the conveying path of the pressure plate, the pre-positioned pressure plate falls into the open pressure start clamping rail. According to this document, however, there is no provision for an electrical interrogation of the correct installation of the pressure plate within the rail.
  • the object of the present invention is therefore to expand a device for checking the registration-correct installation of a printing plate in accordance with the preamble of claim 1, so that a position signal is also available outside the plate cylinder without great expenditure on construction.
  • the correct position of a printing plate should be ascertainable.
  • the signal pick-up of the sensor or sensors within the clamping rail takes place on the frame side movable against the plate cylinder probe heads, which during the insertion of the pressure plate in the clamping rail For example, contact surfaces located on the tensioning rail can be pressed.
  • the electrical signal of the sensor or sensors therefore does not have to be looped out of the plate cylinder via a measured value transmitter, but is taken off (automatically or by hand) with the device according to the invention during the process of inserting the plate.
  • the probes are connected to an evaluation unit, by means of which the signal picked up via the contact surfaces can be evaluated with regard to the correct position of the pressure plate when it is inserted into the tensioning rail. If this is the case, the correct position of the printing plate can either be indicated optically and / or a signal can be given to a machine control, which, for example, causes an automatic clamping of the printing plate (motor acting on the plate cylinder on the frame side or integrated in the plate cylinder).
  • the sensors inside the tensioning rail can be dowel pins which are partially or totally electrically insulated from the tensioning rail and interact with corresponding punched-out areas on the pressure plate front edge. If the dowel pins are completely or only partially insulated from the potential of the plate cylinder, touching the edge of the pressure plate in the area of the cut-out results in a conductive connection between the plate cylinder and dowel pin (short circuit), which after tapping via the probe and contact surface in an evaluation unit as the correct position of the pressure plate can be evaluated within the tensioning rail.
  • the contact surface can be attached directly to the front end of the dowel pin, which protrudes from the tensioning rail.
  • glue special foils or the like which are then the contact surfaces, to the self-electrically insulating tensioning rail.
  • other devices for using the inventive devices also come as sensors Device in question.
  • the sensors can also be integrated in the tensioning rail and can be designed, for example, as buttons or sensors.
  • a plurality of probes are preferably provided which, after corresponding plate cylinder positioning (insertion of pressure plate), can be pressed onto the contact surfaces assigned to the sensors.
  • each individual sensor can thus be queried by an evaluation unit, so that the location of the incorrect system can be inferred.
  • the sensors are dowel pins that are electrically insulated from the plate cylinder and are queried by an evaluation unit to determine the correct position of the pressure plate, the sensors are purely passive elements. A power supply inside the plate cylinder is therefore not necessary. If the sensors are designed as active sensors or the like, a power supply for operating them in the plate cylinder would have to be provided accordingly. This could also be formed by appropriate probes and contact surfaces, but also by a battery or rechargeable battery to be provided in the plate cylinder, which is possible in particular in the case of sensors with low power consumption.
  • the probe heads are mounted on the frame side and are movable relative to the plate cylinder and can be adjusted to the corresponding contact surfaces in the area of the tensioning rail after the plate cylinder has been correspondingly positioned in an angular manner.
  • the or the For example, probes can be suspended in a linearly movable manner.
  • the probes are pivotable about a pivot axis running parallel to the axis of the plate cylinder and in particular attached to a movably displaceable protection in front of the printing unit, and can be pressed against the contact surfaces by an actuating means that becomes effective when compressed air is applied.
  • these probes can be attached at the same axial spacing on a rail which is suspended parallel to the axis of the plate cylinder on a swivel axis . To insert the pressure plate, this rail is placed with the probes on the clamping rail of the plate cylinder.
  • the invention is very advantageous if the probes are attached to a specially designed rail which extends over the format width of the plate cylinder and is to be made in this way on the outer circumference of the plate cylinder in the area of the start of printing, so that this leads to an insertion surface located towards the plate cylinder
  • the front edge of the pressure plate can be inserted into the open detection area of the tensioning rail.
  • Such a rail thus results in a funnel-shaped enlargement of the open detection area of the tensioning rail, one surface being formed by the rail and the other surface being part of the outer circumference of the plate cylinder in the area of the start of printing. Due to the probes placed on the electrically insulated dowel pins, for example, it can now be determined directly during the insertion of the pressure plate into the detection area whether it is correctly seated on the dowel pins.
  • adjustable stops can be provided, via which the probe heads or the rail on the clamping rail directly or on the plate cylinder (bearer ring) are supported so that the force of pressing the probes on the contact surfaces can be limited.
  • the probes are designed as tips which can be pressed under spring force onto the contact surfaces, as are used, for example, in oscillographs.
  • the probes can thus be designed only as a resilient contact or else with electronic components matched to impedance signal voltage tap.
  • the invention is very advantageous if the probe heads are attached to a device which can be adjusted to the plate cylinder and by means of which an automatic or manually supported feeding of a printing plate into the tensioning rail takes place.
  • this can be the case on a printing plate cassette which is pivotably mounted with respect to the plate cylinder, as is known from the prior art.
  • Fig. 1 shows in section the part of a printing unit of a sheet-fed offset printing press in series. Between two side frame walls of this printing unit, a plate cylinder 1 is mounted, which in a cylinder pit 2 has a tensioning rail 3, 4 assigned to the beginning of printing DA and the end of printing DE.
  • a protection 6 is slidably arranged over a guide rail attached to a side frame wall of the printing unit, which is in a basic position according to FIG. 1 during printing operation.
  • the arrow can be pushed up according to the arrow.
  • a pivot axis 7 is preferably attached as a swivel joint, on which a sheet metal profile 8 is suspended.
  • the sheet profile 8 has a slight curvature and has the format width of the plate cylinder 1.
  • a rail 9 is attached or generated by appropriate profiling. This can be turned on or off from the outer circumference of the plate cylinder 1 (FIG. 1).
  • a guide plate 11 is also attached, which extends almost down to the upper edge of the sheet profile 8.
  • a guide plate 12 is also attached to the guard 6, which has two bent legs.
  • Brushes 13 are attached to the concave inside of the sheet profile for the gentle transport of a pressure plate to be fed, so that a new pressure plate to be fed in when the sheet profile 8 is pivoted and thus the rail 9 is set correspondingly to the angular positioning of the plate cylinder 1 (see FIG. 1) directly in the opened one Detection area 17 of the front clamping rail 3 can be introduced.
  • the pressure plate is fed manually through the slot in the two guide plates 11 and 12 (FIG. 1).
  • Brushes 14 can also be arranged on the guide plate 11.
  • a pneumatic cylinder 19 acts on an angle lever 20 together with driving pins for pivoting the sheet-metal profile 8 and the rail 9 in and out (on one or both side frame walls of the printing unit).
  • the sheet metal profile 8 together with the rail 9 is only pivoted for insertion of a new pressure plate into the detection area 17 of the clamping rail 3 and swiveled down again as soon as the new pressure plate is clamped in the clamping rail 3, that is to say attached. Then the mounting of the new printing plate on the plate cylinder 1 begins by slowly rotating the plate cylinder 1 in the direction of the arrow (FIG. 1).
  • FIG. 1 shows this arrangement of the dowel pins 21, 22 in the clamping rail 3 from above. 1 and 3, the dowel pins 21, 22 are attached in a lower part of the clamping rail 3 and extend through corresponding recesses 23 through the upper part of the clamping rail 3, and are thus accessible from outside the plate cylinder 1.
  • the lower part is movable relative to the upper part, the detection area 17 is thus closed by moving the lower part relative to the upper part of the tensioning rail 3 (FIG. 1).
  • Fig. 3 the front edge of a pressure plate D is shown, two punchings 24, 25 are made in this front edge according to the design of the dowel pins 21, 22 and their axial spacing, which with the corresponding dowel pins 21, 22 when the pressure plate D is in correct contact the tensioning rail 3 correspond.
  • a dowel pin 21, 22 is shown in detail.
  • the dowel pin 21, 22 is in two parts executed, the one part consists of the dowel pin 21, 22 with a slot 26 inserted therein on the end face.
  • a filler 27 is inserted as a second part in an electrically insulated manner, which completes the outer contour missing through the slot 26 in the alignment pin 21, 22.
  • An end face of this filler 27 thus forms the contact surface 28.
  • both dowel pins 21, 22 are formed in the tensioning rail 3 according to FIG. 3.
  • a dowel 21 has the slot 26 in the circumferential direction of the plate cylinder 1 and a dowel 22 has the slot 26, for example, inclined at 45 ° to the circumferential direction of the plate cylinder. Due to the electrically insulated connection of dowel pin 21, 22 and the corresponding filler pieces 27, the register-correct system can be checked by touching the edge of the punched-out portions 24, 25 of the pressure plate D. If the edges of the cutouts 24, 25 fit snugly against the outer contour of the dowel pin 21, 22, the filler pieces 27 are connected to one another in an electrically conductive manner with respect to the dowel pins 21, 22.
  • two probes 29, 30 are attached to the rail 9 of the sheet metal profile 8, which press the contact surfaces 28 of the dowel pins 21, 22 directly in the pivoted-in state of the rail 9 (pneumatic cylinder 19 activated) (FIG. 1 and 2). It can thus be determined in an evaluation unit (not shown) whether the filler pieces 27 are connected to one another in an electrically conductive manner with respect to the dowel pins 21, 22 due to the correct seating of the pressure plate D. In a simple embodiment of the invention, it can thus be determined whether the potential of the filler pieces 27 has been pulled down to the electrical potential of the plate cylinder 1 by this short circuit.
  • An electrical conductivity test can also be carried out by the probe heads 29, 30, for example by a current flow is detected. Both direct current and alternating current can be used in such a query.
  • a corresponding threshold value setting in conjunction with adjustable sensitivities also allows changes in the conductivity of the filler pieces 27 with respect to the dowel pins 21, 22 due to the influence of dampening solution or the like to be taken into account.
  • the probe heads 29, 30 and their contacts are of course electrically insulated from the plate cylinder 1.
  • Fig. 2 shows a view from the printing unit, the protection against the printing unit cylinders 6 with the sheet profile 8 and the rail 9 attached to it. Also shown is the guide plate 11 attached to the crossmember 10 and that on the guide plate 11 and the concave inside of the sheet profile 8 attached brushes 13, 14. The sheet profile 8 and the rail 9 are mounted about a pivot axis 7 which extends between two frame parts of the protection 6.
  • two stops 16 are attached, which in particular can be adjustable and, in the exemplary embodiment shown here, serve to engage the rail 9 in such a way on the plate cylinder 1 that there is a defined gap between the insertion surface 15 and the start of pressure DA on the plate cylinder 1 results and on the other hand to avoid excessive pressure forces of the probe heads 29, 30 against the contact surfaces 28.
  • the probes 29, 30 are attached below the insertion surface 15.
  • such a suspension of the probes 29, 30 on a rail 9 providing an insertion surface 15 provides a very advantageous way of querying the sensors formed by the dowel pins 21, 22 on the one hand and on the other hand a very convenient way of inserting a new one Printing plate.
  • the rail 9 and the sheet metal profile 8 remain in position until the pressure plate is inserted into the detection area 17 of the tensioning rail 3 and this detection area 17 is closed after the pressure plate has been correctly positioned. Closing the tensioning rail 3 or of the detection area 17 takes place only when correct positioning of the printing plate has been ascertained via the probe heads 29, 30 which interrogate the alignment pins 21, 22. If the pressure plate was clamped, the rail 9 pivots back into its position shown in dashed lines in FIG. 1 and the pressure plate can be pulled up completely.
