Definitions

  • the subject invention relates to a device for movement a belt, in particular for moving a conveyor belt in a Plant for dewatering a material web, such as a belt or one Felt belt, with a plurality of support rollers and deflection rollers, over which the self-contained belt can be moved all around, with a device for adjusting at least one of the deflecting rollers in the running direction of the belt whereby the tension of the belt can be adjusted is, and with a device for controlling the direction of movement of the Band.
  • At least one of the in the Device arranged deflection rollers in the longitudinal direction of the belt stored and lockable. By adjusting this deflection roller can the tape in the technical requirements Way to be excited.
  • the objective Invention the object of a device for movement to create a volume that is structurally simplified without this affects their functionality.
  • the invention lies thereby the knowledge that the direction of movement of the belt not only by the angular position of the support rollers, but also by the Angular position of the guide rollers is controllable. Based on this knowledge the object is achieved in that each bearing of the deflection roller adjustable in the longitudinal direction of the belt a separate actuating device is assigned, through which the two bearings the deflection roller in different dimensions or different Directions are adjustable, so that by means of the deflection roller Direction of movement of the belt is controllable.
  • An adjusting spindle is preferably assigned to each of the two bearings of the deflection roller, by means of which the two bearings can be adjusted.
  • the adjusting spindles can each be rotated via a bevel gear.
  • an electric motor is assigned to each of the two adjusting spindles, by means of which the adjusting spindles can be rotated, the electric motors being drivable in different directions and at different speeds via a control circuit.
  • a drive shaft driven by a single electric motor is preferably assigned to the two adjusting spindles, a control gear, in particular a superposition gear, being arranged between the drives for the two adjusting spindles.
  • the two bearings of the adjustable guide roller each be assigned a hydraulic actuator through which the both bearings are adjustable.
  • the actuators can each a toothed belt drive or the like. be formed by each an electric motor or by a single electric motor and one Drive shaft, being between the drives for the two toothed belt drives a control gear, in particular a superposition gear, is provided is, are movable.
  • such a device has in a system for dewatering a material web, e.g. one Paper web, at its left end a deflection roller 1, over which a belt 2 is guided, which surrounds the deflection roller 1 at about 180 °. In the direction of movement A of the upper strand of the belt 2 this over a plurality of support rollers. At the right end of this Screen belt device is a second deflection roller, which from Sieve belt 2 is also enclosed by approximately 180 °. Because such Sieve belt device, e.g. in a plant for paper production from the State of the art is known in the drawing, neither the support rollers still shown the right deflection roller.
  • a material web e.g. one Paper web
  • a guide device 3 and 4 for bearing blocks 31 and 41 On both sides of the screen belt 2 there is a guide device 3 and 4 for bearing blocks 31 and 41, in which the two ends 13 and 14 of the axis of rotation 11 of the deflection roller 1 are mounted.
  • the bearing blocks 31 and 41 are formed with bores 32 and 42 which are penetrated by guide rods 33 and 43 aligned in the longitudinal direction of the sieve belt device.
  • the two bearing blocks 31 and 41 are assigned two adjusting devices 5 and 6, by means of which the bearing blocks 31 and 41 can be adjusted in different directions and in different dimensions in the direction of movement of the sieve belt 2.
  • a first position of the bracket 31 is shown in solid lines and two further positions of this bracket are shown in dashed lines.
  • the Actuators 5 and 6 assigned to both bearing blocks 31 and 41 of an electric motor 51 and a gear 52.
  • the output shaft 53 of the gear 52 is an adjusting spindle 55 via a bevel gear 54 coupled to take away.
  • the adjusting spindle 55 passes through in the bearing block 31 located nut thread 34.
  • the output shaft 53 is also on Superposition drives 62, which is driven by a second electric motor 61 is controlled.
  • the output shaft 63 of the superposition gear 62 is via a second bevel gear 64 with a second adjusting spindle 65 coupled, which has a nut thread 44 arranged in the bearing block 41 enforced.
  • the operation of this device is as follows:
  • the output shaft 53 of the gear 52 is rotated by means of the electric motor 51, as a result of which the bearing block 31 is displaced along the guide rod 33 via the adjusting spindle 55.
  • the shaft 63 is also driven via the superposition gear 62, with which the adjusting spindle 65 assigned to the bearing block 41 is rotated via the bevel gear 64.
  • the bearing block 41 is also displaced along the guide rod 43.
  • the exemplary embodiment according to FIGS. 2 and 2a differs from the exemplary embodiment according to FIGS. 1 and 1a only in that there are gears 56 and 66 on the output shafts 53 and 63, via which toothed belts 57 coupled with the bearing blocks 31 and 41 for entrainment and 67 are laid.
  • the toothed belts 57 and 67 are placed at their other end over deflection wheels 35 and 45.
  • the gear wheels 56 and 66 By rotating the gear wheels 56 and 66, the toothed belts 57 and 67 are moved, as a result of which the bearing blocks 31 and 41 connected to them are displaced along the guide rods 33 and 43.
  • FIGS. 3 and 3a differs from the embodiment according to FIGS. 1 and 1a in that a hydraulic actuating device 7 is provided for adjusting the two bearing blocks 31 and 41.
  • This actuating device contains two actuating cylinders 71 and 73 assigned to the two bearing blocks 31 and 41, which are acted upon by a pump 75 via control slides 76, 77, 78, 79 with a pressure medium, as a result of which the pistons 72 and 74 coupled to the bearing blocks 31 and 41 the actuating cylinders 71 and 73 can be adjusted.
  • the control of the pump 75 and the control slide 76 to 79 is carried out by a central control unit 70.
  • the bearing blocks 31 and 41 can be displaced to the same or to a different extent and in different directions, as a result of which the sieve belt 2 can be tensioned and / or controlled in its direction of movement.
  • the embodiment according to FIGS. 4 and 4a differs from Embodiment according to FIGS. 1 and 1a in that the adjusting spindles 55 and 65, an electric motor 81 and 82 is assigned, respectively these two electric motors are controlled by a control unit 80 be that the sense of rotation and the speed of rotation of the adjusting spindles 55 and 65 occurs arbitrarily, causing both a shift of the two Bearing blocks 31 and 41 to the same extent as well as their displacement in different dimensions and in different directions, whereby the sieve belt 2 can be tensioned and / or the direction of movement of volume 2 can be influenced.
  • the two bearing blocks can be displaced independently of one another both in different dimensions and in different directions by at least one deflecting roller, so that when this deflecting roller is adjusted, the screen belt can be both tensioned and controlled in its direction of movement. Since no devices for adjusting the support rollers are thus required, a significant simplification is achieved in the screen belt device.
  • a felt belt can also be provided.
  • Such a device for regulating a band can also other devices in which a self-contained band over Deflection rollers and idler rollers is performed.
