Definitions
- the invention relates to a device for register-correct clamping of a printing plate, the printing plate being clamped on a plate cylinder of a sheet-fed printing machine, the plate cylinder is arranged in a plate cylinder channel, from a front Clamping device and a rear clamping and tensioning device existing plate tensioning device has and in the front clamping device the correct position Passive elements securing and capturing in the lateral and circumferential direction are arranged, which correspond with the pass holes made in the pressure plate and with a control unit are connected.
- DE-GM 77 28 905 such a device is known in the dowel pins in the front clamping device and are arranged isolated from this.
- the passport pens are connected to a voltage source and a signal generator, so that when contact is made of the dowel pins with the dowel holes provided in the pressure plates closed and the signal transmitter is activated.
- the signal transmitter responds even if the pressure plate is not exact is aligned in accordance with the register. This is e.g. the case when deformations in the area of the pass holes or too large tolerances occur and the printing plate is tilted.
- the signal generator is also activated if e.g. the lateral offset of the pressure plate like this It is great that the front edge of the pressure plate lies against the dowel pins or during use of U-shaped fitting holes open towards the front of the printing plate, if the dowel pins are already on one leg of the dowel holes, i.e. without the one in register To reach the position securing bottom area of the pass holes.
- the Dowel pins of this device are also isolated from the clamping device as well as connected to a voltage source and a signal generator. Furthermore the outer surface of the dowel pins has insulation that is partially conductive Section is provided, which is arranged so that only the bottom portion of a fitting hole is detected.
- This device has the disadvantage that the production of the dowel pins is complex. Since the insulating jacket surface is exposed to heavy loads, either this jacket surface or the entire pen is made of ceramic material. This in turn is on occurring sudden loads can not cope with, so an eminent risk of breakage consists.
- the object of the invention is to provide a device for checking the correct position of a To create a printing plate that can be realized with simple means and that that occurs suddenly Loads have grown due to the pressure plate.
- a printing plate 1 is temporarily stored in a printing plate magazine 2. There it rests on two pre-fit pins arranged at a distance from one another 21a; 21b, which have pass holes in the form of punched-out portions 12a, 12b (see in this regard the figure 2) of the pressure plate 1 correspond.
- the cutouts 12a, 12b differ from one another in terms of their shape.
- the Punch 12a has a flat bottom area, while punch 12b has one Radius in the bottom area (see Fig. 2). Common to both is a bilateral Insertion bevel 121a, 121b.
- the cut-outs corresponding to the pre-pass pens 12a, 12b are adapted to one another in terms of their shape. That means specifically that a round pre-fitting pin 21b (not shown) engages in the cutout 12b, the radius of which is adapted to the radius of the punched-out portion 12b.
- the die cut 12a takes a Vorpass pin 21 a, the contact zone with the pressure plate 1, that is the bottom area of the cutout 12a is flat. The side surfaces of the cut-out 12a have no contact with the prefitting pin 21a.
- the printing plate magazine 2 is fixed in its rest position on the frame, not shown attached to the press.
- a plate cylinder 4 is also mounted in the frame Surface to receive the printing plates 1 fed from the printing plate magazine 2.
- a plate cylinder channel on its circumference in the axis-parallel direction 41 arranged.
- a plate clamping device is located in the plate cylinder channel 41 7. This consists of a front clamping device 5 and a rear clamping and Clamping device 6 for receiving the pressure plate end, the front clamping device includes an upper clamp rail 52 and a lower clamp rail 51.
- the upper Clamping rail 52 is fixed to the plate cylinder channel 41.
- the lower clamp rail 51 is displaceable against the upper clamping rail 52 for clamping the pressure plate 1.
- the front clamping device 5 are in the area of the clamping rails 51, 52 as dowel pins 54a, 54b assigned pass elements. It can be seen from FIG. 2 that the dowel pins 54a, 54b in a finite, the distance between the pre-pass pins 21a; 21b corresponding distance to each other are arranged.
- the passport pen 54a analogous to the pre-fitting pin 21a, a flat contact surface to the bottom area of the Die cut 12a, while the dowel pin 54b is adapted to the radius of the die cut 12b Has shape in the area of the contact zone.
- FIGS. 3 and 4 The structure of the dowel pins 54a, 54b can be seen from FIGS. 3 and 4. Both pass pins consist essentially of a foot 547a, 547b on which a guide body 541a, 541b placed and firmly connected to this.
- Figures 3 and 4 is one Top view in the direction of the axis of the dowel pins 54a, 54b shown, the drawing is executed as a section through the guide body 541 a, 541b.
- the insert 542a, 542b is fastened in the guide body 541a, 541b in the Embodiment by a hexagon nut, the insert 542a, 542b interposed Insulating washer 545a, 545b braced against the guide body 541 a, 541b.
- Both inserts 542a, 542b have a probe 543a, 543b.
- the probes 543a, 543b differ in their shape.
- the probe 543a is in its contact area with the punched-out 12a adapted to the flat bottom area and also as a flat one Area executed.
- the probe 543b has a contact area that corresponds to the radius the recess 12b is adapted.
- the registration of the printing plate 1 becomes analogous to the position in the printing plate magazine 2 secured. That is, the guide body 542b and the probe 543b of the alignment pin 54b must have contact to the pressure plate 1 in the recess 12b, while in the Recess 12a only the flat probe 543a with the base of which may contact.
- the printing plate magazine 2 is equipped with a printing plate 1 and from its rest position moved to the position to change the pressure plate.
- the plate cylinder 4 is positioned that a constellation arises that the insertion of a pressure plate 1 in the front Clamping device 5 enables. This position is shown in Figure 1.
- the printing plate 1 is pre-positioned in the printing plate magazine 2 by the pre-fitting pen system.
- a printing plate 1 is removed from the printing plate magazine 2 released by withdrawing the pre-fit pins 21 a, 21 b.
- funding agencies come into play in contact with the pressure plate 1.
- conveyors are in the embodiment Suction cup 3 provided. But there are also transport rollers and other facilities possible. These capture the printing plate 1 and convey it from the printing plate magazine 2 in the direction of the open clamping device 5. In this position, the lower one Clamping rail 51 withdrawn from the upper clamping rail 52 and is located by the top clamp in the most distant position.
- the pressure plate 1 With its punched-out portions 12a; 12b on dowel pins 54a; 54b driven. Is the pressure plate 1 in the register-correct target position (see Figure 2), the contact is through the electrically conductive pressure plate 1 between the dowel pin 54a and the dowel pin 54b closed.
