Definitions

  • the invention relates to a device for winding a material web, in particular Paper or cardboard web, on a reel that is in a primary winding phase is guided by the primary lever and then from the primary lever Secondary lever is passed to further wound in a secondary winding phase to be, whereby the material web is guided over a carrying drum, between the drum or the roll to be formed on it and the carrier drum a winding gap is formed and the drum to generate a line force in the winding gap via a drum holder assigned to the primary levers or the like or can be pressed against the support drum via the secondary lever.
  • Winding devices of this type are for example from the publications DE 101 39 340 A1, DE 35 39 980 C2 and US 3,614,011.
  • Fig. 1 shows a schematic partial representation of a conventional winding device 10, in which the secondary lever 12 by a respective hydraulic cylinder 14th can be acted upon by means of a control device 16 via an actuator 18 can be controlled, which is designed as a proportional directional control valve or control valve.
  • an actuator 18 can be simplified as an electrically adjustable throttle being represented.
  • the pressure actually prevailing in the hydraulic cylinder 14 is detected by a pressure sensor 20 and fed to the control device 16.
  • the actual pressure value obtained is stored in this higher-level control device 16 from the pressure sensor 20 with one supplied to the control device 16 external setpoint value compared, whereupon the control device 16 a corresponding Control signal for the proportional directional valve or control valve Actuator 18 calculates and outputs.
  • 1 also shows the drum 22 of the winding device in question 10 recognizable.
  • the invention has for its object an improved winding device to create of the type mentioned, in which the risk of occurrence of too high linear forces during the transition from the primary winding phase to the secondary winding phase is reduced or eliminated.
  • Control device controllable secondary lever at least in the phase in which they are applied to the newly wound drum, over at least one provided between the control device and the secondary levers Pressure limiting element can be controlled.
  • the force or pressure limitation thus takes place in a separate limiting element, that is provided between the control device and the secondary levers can be and leads to a correspondingly shorter reaction time.
  • the Secondary levers can therefore without the risk of a large line force overshoot practically unrestrained on the newly wound drum become. It is not an elaborate, slow approach to the transfer point more needed. Commissioning, handover and possible troubleshooting is significantly simplified, with time being saved in particular.
  • the force or pressure limiting element preferably comprises a pressure limiting valve.
  • a pressure relief valve over a valve influencing the flow, such as a proportional directional control valve again consists in the fact that the actual pressure control or Limitation takes place directly in the valve itself and accordingly short Response times can be achieved.
  • the force or pressure limiting valve can in particular be a directly controlled one Pressure relief valve include, in which the sealing cone when reaching the Set or set pressure against a spring force from the seat. there can the spring preload, for example mechanically and / or electrically be generated.
  • the winding device is the force or pressure limiting element as an actuator for at least one hydraulic or pneumatic cylinder provided.
  • the control device can be inactive in the application phase or a constant one Deliver the manipulated variable to the force or pressure limiting element.
  • the manipulated variable is preferably selected so that the setting force or the setting pressure just above the force or the pressure for the process of Secondary lever is required.
  • the line or Contact pressure controlled again, for example, according to external setpoints or be regulated.
  • the force or pressure limiting element can be of the set pressure can be variably adjustable.
  • This force or pressure limiting element can for example manually, electrically and / or electronically be adjustable.
  • the pressure relief valve is activated expediently used as an actuator. Then no longer with constant setpoint, but in the classic pressure control loop with setpoint specification according to the selected line force and pressure feedback Pressure transducer.
  • control device is used to control the Movement of the secondary levers each require minimal force or pressure in particular on the basis of determined actual values of the force or the pressure and based on determined changes in the angle of the secondary lever per unit of time can be specified.
  • Fig. 3 shows a schematic partial representation of an exemplary embodiment a device 26 according to the invention for winding a material web a reel 28.
  • the material web can in particular be a Trade paper or cardboard web.
  • the drum 28 guided by the primary lever in a primary winding phase becomes then passed from the primary levers to secondary levers 30 in order to Secondary winding phase to be wound further.
  • the material web is guided over a carrier drum (not shown), which with the drum 28 or the winding 32 to be formed thereon a winding gap forms.
  • the drum 28 is used to generate a line force in this winding gap via a drum holder, load lever or assigned to the primary levers the like or can be pressed against the carrying drum via the secondary lever 30.
  • the secondary levers 30 pivotably mounted about an axis 34 are, for example actuated or pivoted via hydraulic cylinder 36.
  • the secondary levers 30 that can be controlled by means of a control device 38 or Hydraulic cylinders 36 are at least in the phase in which they are on the newly wound Drum 28 can be created via at least one between the control device 38 and the secondary lever 30 or hydraulic cylinder 36 switchable Force or pressure limiting element controllable, that in the present case is formed for example by a pressure relief valve 40.
  • a directly controlled pressure relief valve 40 provided, in which the sealing cone 42 when reaching the setting or Response pressure against the force of at least one spring 44 from the seat 46 takes off.
  • the spring preload can be mechanical and / or electrical, for example be generated.
  • the pressure relief valve 40 thus serves as an actuator for at least one the hydraulic cylinders 36 acting on the secondary levers 30. Via a pressure sensor 48, the actual pressure in the hydraulic cylinder 36 is detected and on the control device 38 passed on.
  • the higher-level control device 38 compares that from the pressure sensor 48 actual pressure value obtained with an external, that is to say externally specified Setpoint to a corresponding control signal for the pressure relief valve 40 calculate and output.
  • control device 38 is preferably inactive in the application phase, that is to say it can in particular supply a constant manipulated variable to the pressure limiting valve 40 in this application phase.
  • the manipulated variable can in particular be selected such that the setting or response pressure is just above the pressure p 1 (cf. FIG. 4) that is required for moving the secondary lever 30.
  • the setting or response pressure forming the limiting pressure is designated “p 2 " in FIG. 4.
  • the line or contact pressure can be controlled using the control device 38 controlled, for example, according to the external setpoints be managed.
  • the pressure relief valve is activated expediently used as an actuator. Then no longer with constant setpoint, but in the classic pressure control loop with setpoint specification according to the selected line force and pressure feedback Pressure transducer.
  • the control device 38 can be used to move the secondary lever 30
  • the minimum pressure required in each case, in particular on the basis of the actual pressure values determined and based on determined changes in the angle of the pivotable Secondary lever 38 can be specified per unit of time.
  • there can be one secondary lever on the driver side and one on the drive side 30 each with an associated hydraulic cylinder 36 and pressure relief valve 40 may be provided.
  • the directly controlled pressure relief valve 40 serves as a seat already mentioned, as an actuator for a respective associated hydraulic cylinder 36. It works as a force comparator. So is the one exerted by the hydraulic pressure Force (actual value) with the spring force, i.e. the force of at least one Spring 44 compared. The spring force in question results from the mechanical or electrically generated spring preload (setpoint). Exceeds the hydraulic Force the spring force, the sealing cone 42 lifts off the seat 46, whereby the Hydraulic cylinder 36 to the tank 50 is relieved.
  • the higher-level control device is inactive during the entire application phase, so the output manipulated variable is constant. It is preferably chosen so that the setting or response pressure p 2 is just above the pressure p 1 that is required for moving the secondary arms 30 (cf. FIG. 4).
  • the expected pressure curve was determined in test bench tests and is in the diagram shown in FIG. 4, from which it can be seen that the overshoot of the pressure and according to the line force during the transition eliminated from the primary winding phase into the secondary winding phase or at least is reduced to a minimum.
  • a secondary lever 30 can be provided on each side his.
  • the secondary lever 30 can now without the risk of a large line force overshoot practically without brakes on the newly wound drum 28 be created. It is not an elaborate, slow approach to the transfer point more needed. Commissioning is much easier, though especially time is saved. Switching to line force control the secondary lever 30 expediently only takes place when when the conditions are stable, i.e. the secondary lever movement is completed. The result is a better quality of the on the Primary levers of wrapped paper.
