Definitions
- the invention relates to a sheet processing machine with a delivery and with a sheet conveying system for conveying sheets on a delivery pile and a method for depositing sheets.
- the sheets are transported by the endless circulating sheet conveying system successively on the sheet stack and with the sheet leading edge against leading edge stops.
- the sheet stacks are provided with stop surfaces in the upper area in the form of such displays, to which a reciprocating movement directed transversely to the sheet transport direction is impressed, whereby the sheets are aligned with respect to their side edge.
- the position of the side edges of the arc fed from the sheet conveying system to the sheet stack with respect to the abutment surfaces is detected by also provided laterally ultrasonic sensors. In case of deviations of the actual position of the target position adjusting elements are activated to correct the sheet position or the sheet promotion is interrupted.
- the measure that the sheet feed is interrupted in case of deviations of the position of the side edges of a desired position reduces the effectiveness of the sheet processing machine in that all sheets are in the machine waste paper.
- the measuring device is designed as a touch sensor, which can detect the Bogenanashsheed and further the contact intensity.
- the measuring device is designed as a receiver of a light beam emitted by a light source.
- a connected control and regulating device changes the timing of the gripper opening and / or the speed (peripheral speed) of the suction roller and / or the suction force of the suction roller and / or the blowing intensity of the fan.
- a disadvantage of this solution is that no crooked or overshoot bow can be detected.
- a device for protecting the gripper systems is known in which a mechanical Koch automattrolle is provided.
- the overshoot arch control contains feeler links that are pivoted about a frame point in an overshoot arc. By swiveling the feeler links, the machine receives the signal "Emergency stop".
- a disadvantage of this solution is that the mechanical scanning of overspill is prone to errors, since the sensing elements cause a safe distance to the gripper carriage track. If an overshoot is not detected, the machine may be damaged at high speeds. Another disadvantage is that no crooked sheets are detected as such.
- a device for detecting irregular sheet design wherein the boom has a first and a second sheet stack downstream therefrom.
- the front edge stops of the first sheet stack is assigned a non-contact sensor that detects an irregular sheet transport and stops the sheet processing machine. This is wasteful, which must be removed from the machine time-consuming, with the individual sensor detects only very far overshoot, while oblique sheets can not be detected as such.
- the invention has for its object to provide a display of a sheet-processing machine.
- the display is designed so that accidents can be excluded by faulty filed sheets and the effectiveness of the machine is increased.
- a display (also referred to as cantilever) is provided for a sheet processing machine with a sheet to an output stack and with a sheet leading edge of the sheets on at least two leading edge stops conveying sheet conveying system, wherein the at least two leading edge stops span a leading edge stop plane, wherein at least a further stop for aligning the delivery stack is provided at a further edge of the delivery stack and wherein at least one detection unit is designed to monitor at least one point downstream of the leading edge stop plane in the sheet transport direction. In this case, at least one of the leading edge stop plane is monitored in the sheet transport direction upstream point. At least one sensor is preferably designed to monitor the at least one point.
- the at least one sensor for monitoring the at least one point precedes the front edge stop plane spanned by the leading edge stops in the sheet transport direction.
- the sensor can be designed as desired and is preferably a non-contact sensor.
- the sensor may be associated with the stack side, such as a side edge stop, and / or the stack trailing edge, such as a trailing edge stop.
- At least two further stops for aligning the delivery stack are provided in the delivery at two further edges of the delivery stack.

- Due to the format setting of the at least one brake element, for example, a suction belt 13.1, carrying braking station is an automatic format setting of the connected Schukantensensors 15.
- it can also be provided with additional braking points with edge sensors 15 so that the accuracy of monitoring the sheet trailing edges can be improved over the format width
- a trailing edge sensor 15 is attached to each braking station, so that an evaluation in the endangered lateral or outer format range is always ensured.
- the rear edge sensor 15 is designed and arranged generating a sensor beam 15.1, so that the sheet fall area can be monitored. It is preferred that each individual falling sheet 7 is detected. In a faulty filed sheet 7, for example, stored on a side edge stop 16 and / or a suction belt 13.1 bends 7.2, an improper sequence of sheets and thus an improper sheet storage is detected. An improper sheet deposition classified as safety-relevant can then lead to initiation of a machine function, in particular to a machine stop, as already described above.
- the Fig. 14 shows a delivery stack 9 from the side with a arranged in front of the delivery stack 9 brake unit 13.
- the brake unit 13 here contains a braking station with circumferentially driven suction belt 13.1 and brake band to delay each released sheet 7 of machine speed to storage speed.
- the Brake station and other braking stations, not shown, are in particular attached to a transversely to the sheet transport direction 39 arranged traverse 14 movable.
- a format-dependent adjustment of the braking stations on the sheet width of the cross member 14 is carried out.
- the traverse 14 can align the trailing edge stop 14, the sheet trailing edge of the sheet 7 to be deposited.
- each rear edge stop 14 may be assigned in particular movable, at which align the sheet trailing edges of the sheet 7 to be deposited.
- the trailing edge stops 14 may, for example, be assigned to the traverse 14 so as to be pivotable about a pivot axis oriented in the sheet transport direction 39.
- the traverse 14 and / or the trailing edge stops 14 each have a stacking area of the delivery stack 9 facing stop surface 14.1, which span a stop plane 14.2.
- the stop plane 14.2 is preferably oriented vertically and transversely to the sheet transport direction 39 aligned.
- the or the rear edge stops 14, the at least one rear edge sensor 15 for detecting the falling sheet 7 is assigned.
- the rear edge sensor 15 may be arranged, for example, above the traverse 14.
- the rear edge sensor 15 is preferably arranged at a distance of 0 to 150 mm, but preferably 10 to 50 mm, from the stop plane 14. 2, that is to say from the sheet trailing edges falling vertically here.
- the trailing edge sensor 15 detects the sheet trailing edge at a height of 20 to 40 mm above the stack surface.
- the at least one rear edge sensor 15 may be associated with the traverse 14 fixed or movable. In order to improve the quality of the measurement result, the one or more rear edge sensors 15 can be designed to be rotatable and / or pivotable.
- the rear edge sensor 15 but assigned to a braking station and thus adjusted with this. Further, the rear edge sensor 15 can be height-adjustable, for example, with the level control of the stacking surface executed.
- the sensor beam 15.1 generated by the rear edge sensor 15 may have an extension directed at least approximately horizontally in the direction of the sheet drop region.
- the sensor beam 15.1 Shown is the sensor beam 15.1 with a downward component. Furthermore, the inclination of the sensor beam 15.1 to the horizontal can also be variable or adjustable.
- the sheets 7 following the sheet fall area pass through the sensor beam 15.1 and are detected at a monitored point 15.2 by means of a receiver or pickup of the rear edge sensor 15.
- the monitored by the rear edge sensor 15 point 15.2 can be within the Bogenfall Kunststoffes or at the sheet trailing edge.
- the sheet trailing edge can be recognized very well, for example as a line from the optical sensor or laser sensor.
- the rear edge sensor 15 is preferably designed such that in each case individual sheets 7 of a sequence successively falling sheet 7 can be detected.
- the one or more Schukantensensoren 15 are connected to an evaluation or control device, such as the machine control in connection. By means of the evaluation or control device, the signals transmitted by the rear edge sensor 15 are compared with predefinable desired values.
- At least two, in particular the outer, or all Schukantensensoren 15 are evaluated together with respect to a single respective falling arc 7. If the tolerance value is exceeded, a corresponding machine function can be initiated. In particular, it is detected as a storage error when a back edge sensor 15 does not recognize the sheet 7 at predetermined times and / or when the angular difference (in particular the machine angle as a condition parameter of the printing machine for a dynamic sheet storage monitoring) or the distance between two successive falling immediately adjacent sheet 7 to big or too small.
- the sensor signals can be interpreted as sheet 7, which hangs firmly in the shaft (clamping arch) or as a sheet 7 which is axially offset over one of the side edge stops 16 and / or trailing edge stops 14 (bends 7.1 or Schiefbogen 7.2). Further, it is provided over the sheet width at least three Schukantensensoren 15 and / or preferably on both sides of the sheet two in the sheet fall direction successively arranged rear edge sensors 15 use. This creates the possibility of determining the falling speed and / or the surface profile of the falling sheets 7. From these results, the fall rate influencing elements, such as fans of the blower frame, blowpipes, etc., targeted, controlled and the sheet fall can be selectively changed.
- the fall rate influencing elements such as fans of the blower frame, blowpipes, etc.
- auxiliary stacking table for example non-stop roller blind 41
- existing sensors such as sensors for determining the stack height, the stack level, etc.
- sensors for determining the stack height, the stack level, etc. can be connected to the evaluation or control device, and their signals are integrated into the results.
- special quality problems such as cornering, for example at the sheet trailing edge, can be detected.
- cornering for example at the sheet trailing edge
- the quality defect can be eliminated.
- the elimination of defects can be done in particular by notification to the printer or automatically by the machine.
- Such a sensor arrangement can likewise be used on an arc side edge, so that the possibility of influencing the sheet deposition can be further improved.
- a sheet position sensor can also be arranged above the delivery stack 9, for determining the surface profile of the falling sheet. 7
- the Fig. 15 shows further forming another sensor 40 below the Schukantensensors 15, which is provided for example as a stacking gap sensor 40 for controlling a non-stop roller blind 41 in an arc gap.
- the sensor signals or data supplied by this stacking distance sensor 40 can be linked, in particular, by the evaluation or control device, for example the machine control, to the sensor signals or data of the or the edge edge sensors 15.
- the evaluation or control device can be made a common evaluation of the sensor signals or data.
- the evaluation or control device can thereby be carried out a check, for example. For plausibility become.
- the achievable accuracy of the position determination of sheet edges by the plurality of sensors 15, 40 can be increased.
- the further sensor technology can be used to test whether retraction of the non-stop roller blind 41 can be carried out without difficulty.
- Continuing education can be found in the detection of the gap between two successive falling sheet 7 to bow influencing means, such as the non-stop roller blind 41, sheet gripper, Bogensauger, Bogenbläser defined in the determined space to move into the stacking plan 9.1 into it.
- bow influencing means such as the non-stop roller blind 41, sheet gripper, Bogensauger, Bogenblvesser defined in the determined space to move into the stacking plan 9.1 into it.
- Further developing a sheet counting by the at least one sensor 15, 40 could be performed.
- the evaluation of the sensor signals can be carried out by the evaluation or control device, for example, such that angle values (in particular of the machine angle as the state parameter of the printing machine for dynamic sheet storage monitoring) are determined when a respective sheet 7 passes a sensor beam 15.1 of a trailing edge sensor 15.
- target values can be stored, for example, as angle values, which can be entered, automatically generated or learned. These target values can be stored depending on the processing speed, sheet format, blowing pressure of the blow frame, etc.
- the error case can be limited or determined. Suitable machine functions can be initiated as a function of the determined error case.
- the sheet position can also be determined from the sensor signals delivered by the stacking edge sensor 40, it being possible to decide after the evaluation whether the non-stop roller blind 41 can enter the curved sheet area unhindered. This prevents in particular that the non-stop roller 41 abuts against a sheet trailing edge during retraction.
- all sensors 15, 17, 25, 26, 30 are regularly cleaned in particular by blown air in order to improve the function. This can be done individually or regularly, for example, in a stack change or actuation of the delivery flap.
- the Fig. 16 shows a stacking plan 9.1 of a display stack 9 with possible monitoring areas.
