Definitions

  • the invention relates to a changing device of a packaging machine for a Supply roll of a film web, the changing device having two support pins, which can be inserted into a sleeve of the supply roll, and with a support pin axially is movable.
  • a changing device of this type is known from DE-OS 3631205.
  • the disadvantage is in the known changing device that a plugged onto the trunnion Supply roll from the bearings of the trunnion a resistance when unrolling the Predate role. This resistance increases the probability of slip of the film web against a transport device to Further transport of the film web and thus inaccurate operation of one Packaging machine.
  • the invention has for its object the resistance of the bearing of the trunnion against the transport device for further transport of the film web equalize, and thus improve the accuracy of the film transport. In doing so the possibility of changing a supply roll by axially shifting one Trunnion should not be affected.
  • the changing device has the advantage that the resistance of the Bearings of the trunnions against the transport device for further transport of the Foil sheet is equalized in that a trunnion is driven by the drive motor becomes.
  • the drive motor rotates the supply roll evenly and over the trunnion such that the film unrolling synchronized with the operation of the transport device he follows.
  • the frictional forces resulting from the bearings of the trunnions are balanced by the power of the drive motor.
  • the transport device experiences thus no retention force from the storage of the supply roll, with which a slip at the Transport device is minimized.
  • Mass moment of inertia of the supply roll is the accuracy of the film transport improved. Since the trunnion together with the drive motor by means of a Actuating device is displaceable in the axial direction, the possibility of changing a supply roll is not affected by axial displacement of the trunnion. Of the Drive motor is moved together with the trunnion and can the trunnion drive regardless of the shift position. You can also do this Storage rolls of different axial dimensions can be used easily and quickly will.
  • the actuating device moves it by means of a Threaded rod via a thread of a connection the connection in the axial direction, and if the drive motor is connected to the connection (claim 2), then the Connection including the drive motor and the sliding trunnion from Motor can be moved in the axial direction. For this shift only the Engine operated at short notice. While in a sense of rotation of the engine Carrying pin is pushed into the sleeve of the supply roll takes place at one in the opposite direction, pulling the trunnion out of the sleeve. Depending on the thread pitch and the engine speed, the Moving process at higher or lower speed. The postponement is particularly accurate when using a servo motor (claim 16).
  • a stable fixation of the drive motor, even during its displacement, is achieved when, analogously to claim 3, the drive motor is connected to a bearing, and the bearing is aligned for displacement of the drive motor in the axial direction is.
  • the exact fixation and stabilization of the drive motor does the same with the trunnion and thus with the supply roll.
  • the supply roll enables an exact film run on the packaging machine.
  • the drive motor it can also be connected to a corresponding one Bearings are connected (claim 4).
  • the same advantages are achieved as with a bearing on the drive motor.
  • a plain bearing (claim 5) has the advantage that it is robust and can be manufactured in a simple manner.
  • Attenuator Is on the second trunnion the displacement of the second trunnion in Axial damping attenuator provided (claim 10), so a constant pressure of the trunnions against the sleeve can be realized.
  • the Attenuator also improves the contact of the sleeve with the trunnion.
  • the pressure is independent of the exact axial position of the sleeve, if that Attenuator is a pneumatic cylinder (claim 11).
  • Is on the supply roll a radially aligned to an end face of the predicate roll Device provided for film edge detection, and this device is a Line connected to a controller of the motor (claim 12), so with the Set up the exact position of the edge of the supply roll to be measured. At If the position is incorrect, the controller corrects the position by pressing the Operates motor for a corrected axial displacement.
  • One edge on the sleeve wound film lies on an end face of the supply roll.
  • the supply roll could but also in accordance with the measured values at another point on the film web measured edge position can be shifted so as to correct the path of the Reach film web.
  • a simple and reliable device for film edge detection has been achieved, if analogous to claim 13 of the device two parallel to each other Extend measuring beams. An exact position is available if only one measuring beam the presence of the film is detected. Both measuring beams register a film or no foil, the supply roll must be moved in one direction or the other will.
  • the controller for the Setting the target position can be a fuzzy controller (claim 15).
  • the fuzzy controller regulates the target position based on stored empirical values. The Experience values in particular allow careful countermeasures recognized, incorrect course of the film web.
  • the changing device is particularly for vertical tubular bag machines (Claim 18) of importance.
  • One of these packaging machines is one simple changing process, a continuous rotation of the supply roll and a reliable correction option for the running of the film web is advantageous.
  • a film web 2 is in Form a supply roll 3 wound ( Figure 1).
  • Two trunnions 4, 5 of the Exchange device 1 are inserted into a sleeve 6 of the supply roll 3.
  • the one Support pin 5 is via a shaft 7 and a gear 8 with a drive motor 9 connected.
  • the drive motor 9 drives the trunnion 5 to rotate.
  • the film web 2 is unwound from the supply roll 3 during the rotation thereof.
  • the support pin 5 is together with the drive motor 9 by means of an actuating device 10 in Axial direction 11 displaceable ( Figure 2).
  • the actuator 10 has a motor 12 with a gear 13.
  • the motor 12 is fixed and moved on a plate 14 by means of a threaded rod 15 a connection 16. Since the drive motor 9 via the Gear 8 and a bracket 17 is rigidly connected to the connection 16, moves the motor 12 through its rotation, the connection 16 together with the holder 17, the Gear 8, the drive motor 9, the shaft 7 and the support pin 5 in the axial direction 11.
  • the threaded rod 15 rotated by the motor 12 runs in a thread 18 the connection.
  • the latter is attached by means of a sliding element 20 a bearing 19 connected.
  • the bearing 19 is for a shift of Drive motor 9 aligned in the axial direction 11.
  • the bearing 19 is a slide bearing 21.
  • the support pins 4, 5 are conical.
  • the second trunnion 4 is with a manually or mechanically displaceable mechanism axially displaceable.
  • Of the Support pin 4 is connected to a round rod 22.
  • the rod 22 is one cylindrical bearing 23 held.
  • the rod 22 is rotatable in the fixed bearing 23.
  • the Bearing 23 is a slide bearing 24 which delimits the rod 22 radially a damping the displacement of the trunnion 4 in the axial direction 11
  • Pneumatic cylinder 26 is provided as an attenuator 25.
  • the pneumatic cylinder 26 ensures a constant pressure of the trunnion 4 against the sleeve 6.
  • the Support pin 4 against the force of the pneumatic cylinder 26 in the axial direction 11 be moved when an exchange of an empty sleeve 6 with a sleeve 6 with a supply roll 3 takes place.
  • a device 28 for film edge detection is on the changing device 1 intended. Two devices run parallel to one another from the device 28 Measuring beams 29, 30 out. If the supply roll 3 is in the correct position, only one hits of the measuring beams 30 against the edge 31 of the film web 2, and the other measuring beam 29 does not hit the supply roll 3 and passes the end face 32 of the supply roll 3 an incorrect position of the supply roll 3, i.e. if both measuring beams 29, 30 die Meet supply roll 3 or pass this, the device 28 to Foil edge detection output signals via a line 33 to a controller 34 passed, and the controller 34 ensures such operation of the motor 12 so that the Supply roll 3 is brought into a correct position.
  • the device 28 for film edge detection and the actuating device 10 can for different functions can be used. While the actuator 10 in principle for a change of the supply roll 3, for an exact positioning of the Supply roll 3 or an ongoing change in the position of the supply roll 3 at Compensation for incorrectness when running the film web 2, as in vertical Flow pack machines can be used is the function of Device 28 depending on the location of the device 28. At the vertical Tubular bag machine, it is advantageous to pull the device 28 off Arrange film web 2 to measure the Vertauf of film web 2, and to by means of an axial displacement of the supply roll 3 an incorrect path balance. For this purpose, in the controller 34 configured as a fuzzy controller 35 stored empirical values can be used.
  • the position of the Supply roll 3 can be recognized.
  • the motor 12 can then in each case are temporarily moved in one or the opposite direction, whereby the supply roll 3 in one or the other direction of the axial direction 11 around is moved a small distance.
  • the motor 12 is a servo motor 38 and has just like the drive motor 9, a reduction gear 39.
