Definitions

  • the invention relates to a device for separating sections of a web of material provided with transverse perforations, preferably of sections of a single or multi-layer paper tube web provided with cross perforations, consisting of a holding double belt conveyor, in which the deflection and / or support rollers or rollers of the or the conveyor belts on the underside of the material web are arranged in the longitudinal direction offset from the deflection and support rollers or rollers on the upper side in such a way that the material web runs undulating through the holding double belt conveyor, and from a tear-off arranged in the conveying direction at a distance from this Double belt conveyor, in which the deflection and support rollers or rollers of the conveyor belts on the underside and the top of the material web are arranged offset to one another in the longitudinal direction.
  • a separating device of this type is known from EP 96 223 A1.
  • the deflection and support rollers or rollers of the upper and lower conveyor belts of the holding double belt conveyor are arranged so offset from one another and shifted against each other so that the paper tube web passing through the holding double belt conveyor is held in a force-locking manner by the conveyor belts.
  • the one or more lower conveyor belts of the tear-off double belt conveyor are driven at higher speed than the one or more lower conveyor belts of the holding double belt conveyor, the upper and lower conveyor belts being set against each other only so slightly that the speed difference to the holding double belt conveyor is preferred for the paper tube web can be compensated for by appropriate slip.
  • the lower support rollers of the tear-off double belt conveyor which are mounted in a carrier that can be moved up and down by an eccentric, are opened in this direction move the support rollers of the upper conveyor belt so that they grip the paper tube section to be severed and thereby pull it forward at a higher speed than the holding double belt conveyor, so that the tear at the transverse perforation takes place.
  • the carrier is then lowered again, so that the separated paper tube section is removed and the following section is drawn in.
  • the known separating device is structurally complex because of the lower support rollers which are vertically displaceably mounted in a carrier and the drive device for the intermittent upward and downward movement of the carrier.
  • the object of the invention is therefore to provide a device of the type specified at the outset, with which sections can be separated from a material web provided with transverse perforations.
  • this object is achieved in a device of the generic type in that at least the support rollers of the upper and lower conveyor belts, including the tear-off double belt conveyor, are constantly shifted so far against one another are that the material web also runs through the tear-off double belt conveyor, that the tear-off double belt conveyor is driven at approximately the same basic speed as the holding double belt conveyor and that the tear-off double belt conveyor is driven intermittently at a higher speed if a transverse perforation or there are several transverse perforations belonging to a separation point between the holding double belt conveyor and the tear-off double belt conveyor.
  • the device according to the invention is structurally simpler because there is no support roller that can be moved up and down by an intermittent drive.
  • the material web runs through both the holding double belt conveyor and the tear-off double belt conveyor in a wave-like manner, at least between the support rollers of the two double belt conveyors, in such a way that they are positively conveyed by both with negligible slip.
  • the tear-off double belt conveyor is briefly driven at a higher speed so that the tear-off tension is generated and the separated section is conveyed away.
  • the following section enters the tear-off double belt conveyor, this has again reached its lower speed corresponding to the holding double belt conveyor, so that until the next demolition there is a preference with a constant basic speed corresponding to the holding double belt conveyor.
  • the cyclically increased speed of the tear-off double belt conveyor which generates the breaking tension can be generated with known drive means.
  • At least one belt of the tear-off double belt conveyor is expediently driven by a servo motor which intermittently accelerates it to a higher tear-off speed and then decelerates it again to the conveying speed of the holding double belt conveyor.
  • Motors with controllable speed are known in different embodiments.
  • the tear-off double belt conveyor can also be driven by a differential gear, the drive of which is derived from the drive of the holding double belt conveyor, the higher tear-off speed being intermittently insertable into the differential gear via a servo motor.
  • the tear-off double belt conveyor is driven by a differential gear, the drive of which is derived from the drive of the holding double belt conveyor, the differential gear being a clutch-brake combination which can be released intermittently in the Assigned in such a way that a higher tear-off speed can be fed into the tear-off double belt conveyor intermittently.
  • the differential gear consists of an epicyclic gear
  • the tear-off double belt conveyor is driven at the same speed as the holding double belt conveyor if, via the clutch-brake combination, the sun gear is coupled to the web carrying the planet wheels, which carries the drive gear for the tear-off double belt conveyor.
  • the sun-wheel is uncoupled from the planet carrier and held fixed to the frame by the clutch-brake combination, the tear-off double belt conveyor is driven at a higher speed in accordance with the transmission ratio of the planetary planetary gear mechanism.
  • the multilayer paper tube web 3 is fed to the holding double belt conveyor 1 in a known manner by feed conveyors and guide devices, of which the last pair of rollers is shown.
  • the holding double belt conveyor 1 consists of lower guide rollers 5, 6 for a lower conveyor belt 7 or lower conveyor belts, of which the front guide roller or guide roller 6 is driven in a known manner by a gear motor 8 and belts or chains 9.
  • the one or more upper conveyor belts 10 run over non-driven deflection rollers 11, 12, the support rollers 13, 14 arranged between the deflection rollers 11, 12 and the rear deflection roller 12 being mounted in a frame 15 which can be pivoted about the axis of the front deflection roller 11 a piston-cylinder unit 16 is pivotable.
  • Support rollers 19, 20, 21 are mounted between the deflection rollers 5, 6 of the lower conveyor belt 7, the deflection rollers and support rollers of the upper and lower conveyor belts being arranged offset to one another in the manner shown.
  • the piston-cylinder unit 16 By means of the piston-cylinder unit 16, the frame 15 is lowered or lowered against the rollers of the lower conveyor belt in such a way that the tubular web 3 runs through the holding double-belt conveyor in a wave-like manner in the manner shown and essentially without friction from the conveyor belts 7, 10 is held so that the holding double belt conveyor 1 is able to absorb the intermittently applied tearing tension without substantial slippage.
  • the holding double belt conveyor 1 corresponds essentially to the preferred station 32 described in EP 98 223 A1, so that reference is made to this for further explanation.
  • the tear-off double belt conveyor 2 is basically constructed identically to the holding double belt conveyor 1, so that reference is made to the above description of the holding double belt conveyor.
  • a difference of the tear-off double belt conveyor 2 compared to that Holding double belt conveyor 1 essentially results only from the drive 25.
  • the drive 25 of the tear-off double belt conveyor consists of a gearbox with a servo motor which drives the lower conveyor belt or belts of the tear-off double belt conveyor 2 at a basic speed corresponding to the holding double belt conveyor drives.
  • the servo motor intermittently drives the tear-off double belt conveyor to apply the tear-off tension at a higher speed.
  • the servo motor of the tear-off double belt conveyor 2 can be provided with a corresponding intermittent or cyclic control.
  • sensor devices can also be provided which detect the entry of the transverse perforation 4 into the gap between the two double belt conveyors and then generate a signal which accelerates the servo motor.
  • the advantage of such a device lies in the fact that an undisturbed tear-off can also be carried out without retooling work if the length of the sections between the transverse perforation lines 4 changes.
  • the paper tube web 3 is a multi-layer paper tube web, from which sections for sack production are separated.
  • the transverse perforation lines of the individual paper layers are staggered in a known manner at the tearing points 4.
  • the lower belt 102 runs over the drive roller 101 of the tear-off double belt conveyor.
  • the shaft journal 103 of the drive roller 101 is in the manner shown via roller bearings in a wall 104 of the frame is supported and extends beyond the frame wall to the left.
  • a gear 105 is wedged onto this end of the shaft journal 103 which projects to the left and meshes with a further gear 106 which drives the drive roller 107 of the upper belt 108.
  • An external ring 109 with internal teeth is firmly screwed to the gear 105 and is part of a differential gear in the form of a planetary gear.
  • the internal toothing of the ring gear 105 meshes with the planet gears 110, which are freely rotatably connected to the drive gear 111.
  • This drive gear 111 is driven by idler gears from the holding double belt conveyor at the same speed.
  • the drive gear 111 is freely rotatable on a shaft 113, which in turn is mounted at one end in the gear 105 and at its other end via ball bearings in the hub of a brake disc 114.
  • This brake disc 114 is screwed to a frame cover 115, which in turn is screwed to the machine frame 16.
  • the brake disc 114 fixed to the frame is provided with an electrical ring magnet 117 in its hub.
  • a ring 119 is fastened on the shaft 113 and has a ring shoulder 120 on its left side.
  • the ring 119 passes through a compression spring 120 ', which is supported on the one hand on the annular shoulder 120 and on the other hand on a locking ring 121 which is held in the hub 122 of an axially displaceable but non-rotatable brake disk 123.
  • the brake disk 123 is thus pressed to the right by the compression spring 120 ', so that the brake disk 123 engages non-positively against the brake disk 124, which is firmly connected to the drive gear 111 via an annular holder 125.
  • a sun gear 126 meshes with the planet gears 110 and is fixedly connected to the shaft 113.
  • the brake disc 123 is non-positively pressed against the brake disc 124, so that the sun gear 126 is coupled to the drive gear 111 and the output speed of the gear 105 is equal to the input speed of the drive gear 111.
  • the ring magnet 117 If the ring magnet 117 is now supplied with current, it pulls the axially displaceable brake disk 123 against the force of the compression spring 120 'against the brake disk 114 fixed to the frame, so that the brake disk 123 and thus also the sun wheel 126 are held fixed to the frame. As a result, the speed of the gear 105 increases in accordance with the gear ratio of the planetary epicyclic gear compared to the drive gear 111.
  • the ring magnet 117 is switched in time with the desired breaks, so that the tear-off double belt conveyor without a servo drive can be given a higher speed intermittently.
