Definitions
- the invention relates to a method for adjusting the Falzspaltenweite several Falzwalzencrue, which are provided on a folding machine.
- a folding machine which several consecutively Has folded pairs arranged in the sheet travel direction, between which in each case a bow is performed.
- a folding roller of the first pair of folding rollers is arranged stationary, while the other folding rollers to form a folding gap arranged adjustable with the other folding roller of the corresponding folding roller pair is.
- the adjustable folding rollers are each by a biasing device biased in the direction of the stationary roller.
- a thickness gauge which is the thickness of a first continuous sheet supplied to the first Falzwaizencru. Of the The measured value determined is forwarded to a process computer. There are under Considering a respective folding scheme the necessary folding gap widths calculated.
- the actuators for adjusting the adjustable folding rollers actuated until the actual values of the position report are the calculated one Correspond to target values. Corrections can be made both through a keyboard as well over parallel to the motor drives acting manual spindle drives, the also act on the position indicator done.
- the invention is based on the object, a method for adjusting the Falzspaltenweite provide multiple Falzwalzencrue, with the Falzspaltenweite on simple and precise way can be automatically adjusted and corrected.
- the Falzspaltenweite in the passage of a Arc is measured on all pairs of folding rollers and the Falzwalzenspalt then by the associated drive at each pair of folding rollers accordingly is set to the acquired measured values, is no complicated calculation of Folding gap widths depending on a thickness measurement required, as in the known from DE-298 20 796 known prior art is the case.
- the invention Method works without single sheet thickness measurement and faulty Gap width calculation.
- air pockets, the sheet compression, the roll wear and the roll contamination considered become.
- a correction of the Falzspaltenweiten is by a corresponding control the drives by a process control possible, the correction values from an operator terminal, e.g. a keyboard can be entered.
- Such folding schemes are e.g. a zigzag fold or a spiral fold.
- the recorded measured values can be used to determine a roller wear or a roll contamination with predetermined or measured Reference values are compared.
- the folding rollers by means of with an adjustable folding roller kinematically connected drive brought into contact with each other.
- the Taschenfalzwerkmaschine 10 has six parallel folding rollers 12 to 22, which are arranged in the sheet passage direction B successively.
- the folding rollers 12 to 22 form 5 pairs of folding rolls, wherein the first folding roller pair of a stationary rotatably mounted folding roller 12 and the adjustable folding roller 14, the second folding roller pair of the folding roller 14 and the adjustable folding roller 16, the third folding roller pair of the folding roller 16 and the adjustable folding roller 18, the fourth pair of folding rollers of the folding roller 18 and the adjustable folding roller 20 and the last pair of folding rollers from the folding roller 20 and the adjustable folding roller 22 is formed.
- the first to fourth pair of folding rollers each have a folding pocket 24 to 30 downstream.
- the folding roller 14 is at the free end of an arm 34 of a two-armed arm 33 rotatably mounted, which is a machine-fixed Axis 36 is pivotable. On the second arm 35 of the handlebar 33 engages a Compressive spring 38, biased by the folding roller 14 in the direction of the folding roller 12 becomes.
- the second arm 35 of the handlebar 33 is also for adjustment the Falzspaltenweite between the folding rollers 12, 14 kinematically with an actuator 42 connected.
- the handlebar 33 is associated with a displacement measuring system 40, which measures the deflection .DELTA.S of the link 33.
- the actuators 42 and the path measuring systems 40 are connected to a process computer 44 connected to the actuators 42 based on the of the Wegmesssystemen 40th controls measured values.
- a control panel 46 connected, by means of which folding parameters and correction values the process computer 44 can be entered, this in the control the actuators 42 considered.
- controllable actuators 42 e.g. electrical Spindle drives, linear motors, voice coil drives, hydraulic cylinders or pneumatic cylinders be used.
- the folding pockets 24 to 30 are in a known manner provided with actuators 48 through which the folding pockets the desired folding scheme can be adjusted accordingly.
- the actuators 48 of all folding pockets 24 to 30 from the process computer 44 in dependence on desired folding scheme driven and set the folding pockets 24 to 30.
- all of the process controller 44 acting on the handlebar 33 actuators 42 driven so that the folding rollers 12 to 22 of the individual folding roller pairs come into contact with each other, so that the width of the Falzwalzenspalte "0" is.
- the link 33 by the compression springs 38 in the direction of the other Pre-tensioned folding roller of the folding roller pair.
- the distance measuring systems 40 can so be adjusted or preset that the measured path of the deflection of the Handlebar 33 is "0".
- an arc between the first folding roller pair 12, 14 introduced and passes through the pocket folder 10 according to the desired folding scheme.
- the individual are adjustable Folding rollers 14 to 22 of the sheet thickness deflected accordingly. This deflection corresponds to the width of the Falzwalzenspalte, the following for the processing Bow is optimal.
- the deflection is in each case by the displacement measuring system 40th measured and passed a corresponding measured value to the process computer. Thereafter, the process computer 44 controls the actuators 42 so that the before first arc passage set by the displacement measuring system measured deflection becomes. Possibly. Correction values can be entered via the keyboard 46.
- all Falzwzwenspalte optimized are possible for the passage of more sheets through the Taschenfalzwerk 10 optimized.
- a set value which was determined by a pattern sheet (1st sheet) forms a setpoint for the nip adjustment.
- This setpoint can be in the production process be constantly compared with the current actual value, making it possible is, changes in the Falzwalzenspalt (for example, by roll contamination, roller wear, Paper thickness change) immediately in the production process and display.
