Definitions
- the invention relates to a control for the stack stroke drive of a sheet processing Printing machine, in particular for feeders and / or delivery of a sheet-fed offset printing machine, according to the preamble of claim 1.
- the sheets to be printed are from the top taken from a stack of sheets, over a system table to a system and from there one first printing unit fed.
- the printed sheets are in the delivery on the top of a stack of sheets filed in the work cycle of the machine.
- the stack of feeders or booms load-bearing stack support plates are in this case by assigned stack lifting drives Feeder or boom can be moved in height.
- the stack support plate is moved such that the top of the sheet stack in one intended height range remains.
- the stack support plate of the Stack of sheets in the delivery here also according to the signals of the stack height scanning the control assigned to the motor of the stack lifting drive is the lowering of the Stack support plate causes.
- the stack support plates in the feeder and delivery of sheetfed offset presses must but not only the tracking movement described above during printing but especially for a manual or automatic batch change (Non-stop operation) within larger areas.
- the stack support plate must be used when changing the stack manually or when placing a new pallet to be completely lowered to the ground.
- additional positioning operations of the stack support plate must also be carried out, in particular to combine the main stack with the auxiliary or residual stack.
- DE 4 207 305 A1 describes a device for controlling the stack carrier in printing machines known, here the stack carrier with an electrical displacement measuring device for constant detection of its position and for the transmission of measurement data to a programmable Computer connected to determine the vertical position of the stack carrier is.
- a distance measuring device is used, for example, along the guidance of the stack carrier arranged measuring strips proposed in connection with a scanner.
- Another embodiment of the device described is a via a reduction gear rotary potentiometer connected to the drive motor of the stack carrier provided, the analog measuring voltage with respect to the position of the stack carrier can be further processed is.
- DE 3 631 456 C2 describes a device for controlling a stack lifting device known in which the control of the stack lifting device is a device in the form an impulse or incremental encoder to determine one dependent on the tracking path Size and a clock for generating information about the working speed is assigned to the machine.
- This device described in this document serves in connection with a double sheet control of the adjustment of the tracking movements of the sheet stack to the work cycle of the machine depending on the substrate thickness.
- a stack lifting device as a brushless one Drive DC motor trained drive motor.
- the brushless DC motor is used for loading and unloading as a DC motor Self commutation and during the printing process in a second mode of operation Stepper motor operated with external commutation. This allows you to change stacks Achieve higher travel speeds, however, especially for reasons of personal protection additional security measures required.
- DE 9 202 352 U1 is a safeguard for a stack lifting device for sheet stacks known in sheet-fed printing machines, in which a switching of the stack travel speed between a high and a low value by at least one in two switching stages switchable switching element, which with the stack support plate or with the top of the sheet stack cooperates, is actuated.
- the stack support plate can first be moved at high speed, after which a first actuation of the switching element described to a lower speed is switched to the subsequent approximation with higher accuracy achieve.
- a disadvantage of this device is the mechanical effort in particular the switching device described.
- the object of the present invention is therefore to provide a control for the stacking stroke drive according to the preamble of claim 1, so that while avoiding the above-mentioned disadvantages, a flexible control option for a stack lift drive can be achieved, in particular the strict requirements of personal protection must be feasible.
- the controller switches the travel speed for the drive motor of the stacking stroke drive to a lower speed value, so that in the case of Operating an electrical safety device (e.g. an operator's foot between the floor and stack support plate) the movement of the stack support plate by stopping the drive motor is stopped as quickly as possible and without slowing down caused by inertia.
- an electrical safety device e.g. an operator's foot between the floor and stack support plate
- the movement of the stack support plate during an automatic stack change in non-stop operation is the travel speed for the stack support plate by the invention trained control specified depending on the position of the stack support plate.
- the measuring device for detecting the Position of the stack support plate and for deriving information about the speed the method of the stack support plate as a via a reduction gear with the drive motor the stack lifting device coupled angle encoder.
- This angle encoder are absolute angular values over a number of lines in the manner of a parallel bus Removable, so that digital information is already available with each switch-on about the position of the stack support plate. It is intended that the reduction of the reduction gear between the drive motor and the angle encoder is such that the entire travel range of the stack support plate between the floor and the maximum maps possible travel height to an area ⁇ 360 ° of the rotor of the angle encoder.
- one of the Evaluation unit arranged downstream of the angle encoder especially after installation of the angle encoder, the current position of the stack support plate is entered once (e.g. via Hand terminal or laptop), from which a calibration of the angle values of the angle encoder is then obtained to the entered reference value. It is therefore not necessary to use the angle encoder after exchange of gear parts or other measures in the stacking stroke drive mechanically to adjust.
- the angle encoder supplying absolute angle values it is possible to add the least significant bit of the angle value information, in particular in conjunction with higher-value bits, permanent for determining the speed evaluate the stack support plate during operation of the drive motor. Anytime there is therefore one or two evaluation units downstream of the angle encoder digital information about the current (vertical) position of the stack support plate as well as about their travel speed. According to a further development according to the invention, that in addition to the controller evaluating the position information of the angle encoder additional monitoring device is provided along with another evaluation unit, which a deviation in the travel speed of the stack support plate is additionally detected and by which when the maximum permissible speed is exceeded the The drive motor of the stacking stroke drive is immediately stopped and a mechanical brake is engaged becomes.
- the chains 3 are in operative connection with a drivable Sprocket shaft 4, this via a gear 5 with a drive motor 6 is coupled.
- An electrically releasable brake is also assigned to the drive motor 6, which is not shown in the figure, and in particular manages that at Switch off the power or other emergency or dangerous situations the stack support plate 1 can be locked in the respective position.
- the drive motor 6, in particular as a brushless DC motor with a corresponding Electronic commutation is trained, for example, directly on the shaft and a reduction gear 8 connected to an absolute encoder 9.
- the reduction of the reduction gear 8 for coupling the angle encoder 9 is such that the entire travel of the stack support plate 1 in particular between the floor and a maximum attainable upper position within a feeder or boom does not quite cause one rotation of the rotor of the angle encoder 9.
- a method of the stack support plate 1 between the floor and indicated in the figure A maximum attainable upper position means that the digital values of the Angle encoder always different and the position of the stack support plate 1 clearly reproducing Accept values.
- the angle encoder is 9 connected directly to the shaft of the drive motor 6 via the reduction gear.
- the reduction gear 8 can also be indicated with the gear 5 of the sprocket shaft 4 or be attached to the sprocket shaft 4. According to the invention it is crucial that the total travel of the stack support plate 1 is less than one revolution of the angle encoder 9 or that the entire travel of the Stack support plate 1 maps to an area ⁇ 360 ° of the rotor of the angle encoder 9.
- the angle encoder 9 is designed as an absolute angle encoder, i.e. this are on a number of lines providing binary signals or in the form of a serial Data flow immediately after switching on the devices its rotor position (encoder disc) corresponding digital signals can be removed.
- the angle encoder 9 is followed by two Evaluation units 10.1, 10.2 connected, via which after entering a reference value the current vertical position of the stack support plate 1 within the feeder or boom can be determined.
- the reference value entered is assigned to the at the input of the currently applied digital angle value, so that now all positions (Positions) of the stack support plate 1 in the feeder / delivery by specifying a digital Angular values can be determined and approached.
- the evaluation units 10.1, 10.2 which the digital signals of the angle encoder 9 correspond to those made above Data to be converted are operatively connected to a controller 7, via which, according to the position signals, energizing the drive motor 6 for Approaching predetermined positions of the stack support plate 1 takes place, and on the other hand with one Monitoring device 12, through which a determination of the maximum allowed Travel speed as a function of the position signals of the angle encoder 9 and a Comparison with the current travel speed is carried out.
- the controller is also capable 7 not only perform position control for moving to predetermined positions, but also the travel speed depending on the respective position of the To control the stack support plate 1 by appropriately energizing the drive motor 6.
- the controller 7 receives the digital position signal of the position of the stack support plate 1 via the evaluation unit 10.1. Furthermore, in the evaluation unit 10.1, the travel speed of the stack support plate 1 is determined from the signals of the angle encoder 9 and compared with the maximum values defined in the controller 7 as a function of position. Permissible maximum speeds are stored in the controller 7 for various commands, to which these can be fed via an input device 11, which are activated depending on the position signals of the angle encoder 9 for moving the stack support plate 1 depending on the respective command. In order to lower the stack support plate 1, for example activated by hand via the input device 11, the stack support plate 1 is first lowered at a first speed V max1 until the stack support plate has reached an intended height above the floor.
- the controller 7 then switches over to a second travel speed V max2, by means of which the stack support plate 1 is lowered completely onto the sheet via the drive motor. It applies here that a lower speed is selected for moving to the end position than the travel speed above the minimum height for lowering the stack support plate 1. V max2 ⁇ V max1 therefore applies .
- the maximum speeds stored in the controller 7 for a multiplicity of operating commands which on the one hand can be entered manually via the input device 11 or are triggered by the higher-level control of the machine, are assigned to specific position ranges, ie these position ranges are parameterized with different travel speeds. These assignments are also stored in the evaluation units 10.1, 10.2.
- the above-described lowering of the stack support plate 1 by switching a travel speed from V max1 to V max2 corresponding to the position of the stack support plate achieved by evaluating the signals of the angle transmitter 9 in connection with the downstream evaluation unit 10.1 is only exemplary, in particular, this is also how travel processes are carried out Stack support plate 1, for example during an automatic stack change in non-stop operation to combine the remaining or auxiliary stack. It is essential that the control unit 7 stores speed setpoints for the position signals that can be detected by the evaluation unit 10.1, depending on the drive motor 6, the stack support plate 1 is moved at the respectively provided travel speed.
- the corresponding switches are the Travel speed of the stack support plate 1 can be carried out automatically without being in the travel path the stack support plate 1 additional shift levers, sensors or the like are to be provided.
- FIG. 1 also shows the monitoring device already mentioned above 12, which via the evaluation unit 10.2 with the angle encoder 9 for position detection the stack support plate 1 is connected. Like the controller 7 (from the evaluation unit 10.1) also receives the monitoring device 12 from the evaluation unit 10.2 via a Line Vü a signal when the travel speed of the stack support plate 1 exceeds the position-dependent maximum value. In this case, the drive motor 6 stopped by the monitoring device 12.
- the evaluation units 10.1, 10.2 are preferably once as a programmed processor and once designed as a hardware assembly and each serve to convert the Digital signals from the angle encoder 9 in from the controller 7 or the monitoring device 12 usable position values (signal Pos in Fig. 1).
- the evaluation units 10.1, 10.2 are also the actual values of the traversing speed from the encoder signals the stack support plate 1 formed (evaluation of the pulse sequence of the least significant bit of the Angle encoder 9) and compared with the stored maximum values.
- About accordingly formed signals on the lines Vü takes place when the predetermined Maximum values for stopping the drive motor 6 via the controller 7 and the monitoring device 12.
- the monitoring device 12 can also be shown in FIG Way with an electromagnetically actuated assigned to the drive motor 6 Brake connected and this when a speed deviation is detected press immediately.
