Definitions

  • the present invention relates to a station for introducing a strip material, for example cardboard, to a station working it sequentially, such as a platen press.
  • the platen press being a machine requiring a temporary stop of the running of the strip material during the cutting work, it occurs, due to the continuous feeding, an accumulation of strip material before this cutting platen.
  • the machine builders have therefore designed an introduction station making it possible to cyclically control the formation of a loop of strip material so as to minimize the breakdown effect of this strip at the instant when the loop touches the loop adjusting member, and this by using a device conducting the strip material around the circumference of an eccentric roller mounted between two rotary plates as described, for example, in Swiss patent CH 602 462.
  • the constant speed VO of movement of the tape at the entrance to the station is transformed, at each working cycle of the machine, into an intermittent speed VIT while keeping a constant tension in the belt.
  • the strip material exiting with a modulated speed from the eccentric roller is led by a last roller, called “introduction roller", towards the plate.
  • introduction roller a last roller
  • the peripheral speed of this introduction roller VRO is fixed at a fairly high value, greater than this maximum.
  • the feed roller is permanently driven by the main motor and a gear train of the station at a constant speed of rotation so that its peripheral speed always remains greater than the momentary speed of travel of the strip material, which results in permanent slippage of the strip on the feed roller.
  • the work of the friction forces present on the bank / roller contact surface dissipates into heat, which requires a significant cooling device for this introduction roller.
  • this device quickly finds its limit as soon as it is envisaged to increase the production rate, therefore the running speeds; and especially in the case of cardboard coated with a delicate layer on the back side, for example a layer of polyethylene. Then, the heating and the frictional forces present between the introduction roller and the cardboard heat and partially tear off this delicate layer, and plastic material is found in a pasty state in the female refusers of the plate. In addition, inadmissible acceleration marks appear on the cardboard depending on the position of the insertion belts.
  • the object of the present invention is to obviate the aforementioned problems by proposing an introduction station allowing a higher operating rate, even for delicate cartons, while preserving the integrity of the material of the strip or of a layer. peripheral, and respecting the mechanical limits of the machine's drive members.
  • an introduction station comprising an eccentric roller mounted between two rotary plates around which the strip material passes so that its speed of movement is transformed from a constant input speed VO into a speed of VIT output evolving according to a predetermined speed during a work cycle of the station, as well as an introduction roller guiding the strip of material from the eccentric roller towards the plate, due to the fact that the introduction roller is driven by an independent device such that its peripheral speed VR follows a speed similar to the speed of exit VIT of the strip material while remaining permanently at a higher value.
  • the independent drive device of the introduction roller consists of a direct current electric motor supplemented with a reduction gear limited to two pairs of toothed wheels.
  • the electric motor is connected to the shaft of the feed roller by two gears, the first having a ratio of about 20:36, the second a ratio of about 15:38, the moment of inertia total of the cylinder, gear and motor as reported at the level of the motor output axis not exceeding 0.04 kgm2.
  • FIG. 1 is illustrated an introduction station 10 receiving upstream a strip of material 5 with a constant speed VO, and delivering downstream this strip 5 with an intermittent speed VIT to a platen press 20.
  • the strip 5 passes around a roller 13 with low inertia and mounted eccentrically on two lateral rotary plates.
  • the strip forms a loop of controlled dimensions, the exit speed being almost zero during the formation of this loop.
  • the pair of rollers 11 imposes a belt tension for the upstream path, while an introduction roller 15, directing the band towards the platen press, maintains the tension in the loop thanks to friction forces because its Peripheral speed VR remains at all times greater than the momentary speed VIT of the tape.
  • the AVIT progression of the belt at the exit of the loop is no longer proportional to the general drive of the machine, but, after being zero during the descent of the eccentric roller, is very quickly during the ascent.
  • the intermittent speed VIT of the strip therefore follows a bell-shaped regime optimized as a function of the characteristics of the material of the strip, a regime whose average value over the cycle corresponds to the arrival speed VO which is usually of the order of 3.5 m / s.
  • the ACIT curve represents the corresponding acceleration regime comprising an acceleration to around 190 m / s2 then a deceleration of the order of -255 m / s2.
  • the cylinder 13 is driven by an independent electric motor 35 through a reducer constituted by a double gear 40/42 and 44/46. Thanks to this motor 35, the roller is no longer driven at a constant speed, but according to a speed VR1 or VR2.
  • the speed VR1 of the feed roller increases then decreases linearly from a value of 2 m / s to a value of 9.2 m / s, the acceleration then braking ACR1 applied by the motor being constant.
  • the speed VR2 of the introduction roller evolves according to a bell-shaped regime closer to the speed regime VIT of the strip.
  • the acceleration ACR2 then passes through a maximum.
  • the area S2 represents the residual speed difference between the strip and the roller, now reduced to an optimized value to maintain sufficient tension in the strip and to minimize heat loss.
  • the moment of inertia of the introduction roller 13 and its drive device is evaluated, in known manner, step by step, taking into account the moment of inertia of each of the components, namely of the roller 13 with its rotation shaft 47, the driven bevel gear 46, the driving bevel gear 44, the shaft 45, the driven gear 42, the driving gear 40, the output axle 36 and the motor 35, and this taking account of the reduction ratios, for example 15:38 at the level of the wheels 44/46 and 20:36 at the level of the wheels 40/42.
  • the total moment of inertia reduced to the level of the motor 35 can typically be of the order of 0.03 kgm2, and in any case less than 0.04 kgm2.
  • the maximum torque required by the motor is equal to the product of the moment of inertia by the maximum angular acceleration required.
  • the load torque initially planned for the continuous drive of the feed roller on the differential and the kinematic chain of the general drive of the machine can be compensated by a Engine brake.
  • the energy balance is then made via the electrical network.
  • the speed reference according to a predetermined profile applied to the electric motor can be done in a known manner by computer and electrotechnical means.
