Definitions

  • the present invention relates to the field of machines for continuously unwinding and rolling web materials, in particular machines for unwinding rolls of paper or cardboard, for the purpose of feeding a machine downstream and for the purpose of a method of positioning strips and coils for connection to a machine to unwind.
  • the invention also relates to a device for implementing this method.
  • a coil being scrolled is placed on one of the two pins of a machine to unroll.
  • a new coil is placed on hold on the second unwinding pin of said unwinding machine.
  • the beginning of the strip of this new coil must be positioned so that it is correctly aligned both laterally and angularly with the finishing band.
  • the new coils and strips are pre-positioned by the operator using graduated scales arranged on the spindle carrying the spool and on the preparation area of the beginning of the tape waiting for connection.
  • the operator will slide the spool onto the spindle until the end of the mandrel, made of cardboard or other material, of the spool is placed in close proximity.
  • a reference 600 mm corresponding to the graduated scale of the spindle bearing said coil so that the -flanc heart of the coil is placed as accurately as possible in front of the reference 600 mm corresponding, that is to say say either aligned with this mark.
  • the operator will unroll a sufficient length of the new band that will have in front of the reference 600 mm of the ruler graduated from the holding zone of the beginning of this new band. In this way, an apparently correct alignment is achieved between the new reel and the unrolling machine and the new web will be able to scroll in the unwinding machine without risk of slanting.
  • the new coil has a defect in shape, for example when the flank at the outer diameter of the coil is not plumb with the flank at the inside diameter, then the beginning of the new strip may be placed, in the preparation zone of the beginning of the strip, at an angle to the longitudinal axis of the machine. This results in malfunctions, including longitudinal folds that can cause breakage of the tape running or damage the main part of the production line.
  • these sensors do not emit a visible light beam to materialize a position, that is to say, allowing an operator to perfectly locate a vertical plane, in which the edge of a coil must be positioned, without intervention of specific means of enslavement.
  • US-A-5,133,511 describes a positioning method of measuring the position of a band by means of a a position sensor and a CCD camera which, as a function of the number and the position of the activated pixels of the sensor, informs a control and control member on the position of the strip.
  • This method uses a light source which is a lamp illuminating the area filmed by the CCD camera and is not adapted to the materialization of a position by issuing a line of light.
  • US-A-4,131,206 also discloses a tape positioning method, wherein the tape is moved laterally until a light flux of a light beam emitted by a light source and picked up by a receiver is interrupted.
  • This method uses a means of the photoelectric barrier type, the source of which is not intended to materialize a position on the tape, but to illuminate a receiver informing a controller on the position of the tape.
  • the present invention aims to overcome the disadvantages of known methods and devices by proposing a method of positioning strips and coils for connection to a machine to unwind and a device for implementing this method to ensure a perfect alignment between the finishing band and new band and a strip unwinding without longitudinal folds by performing a set of operations entirely under the control of an operator verifying the position, without implementation of complementary electronic control means and / or complex and expensive computer
  • the method according to the invention is characterized in that it consists in materializing, at the outer diameter of a coil, by means of a light beam emitter of visible light by an operator and without setting implementation of an active receiver, the position at which the side of said coil is to be positioned relative to the longitudinal axis of the unwinding machine.
  • the invention also relates to a device for implementing this method, which is characterized in that it consists essentially of at least one light beam emitter in the form of at least one linear beam or from less a light plane of visible light by an operator, said transmitter cooperating with a passive indexing means, without implementation of an active receiver.
  • FIG. 1 of the accompanying drawings shows a machine for unwinding rolls of paper or cardboard for feeding a downstream machine such as a printing machine or the like, this machine consisting essentially of a support frame 1 means 2 coil carrier 3, movable transversely to the longitudinal axis of the machine, and optionally a tape accumulation device 4 and a set 5 for preparing a new band to connect and junction of this tape to a finishing tape.
  • a device which consists essentially of at least one emitter 6 of light beam in the form of at least one linear beam or at least one plane light of light visible by an operator, said transmitter cooperating with a passive indexing means 7, 71 ( figures 2 and 4 ) provided on the assembly 5 for preparing a new band to connect and joining this band to a finishing band, without implementation of an active receiver.
  • the positioning of strips and coils for connection consists of loading a spool 3 on the free spindle of a means 2 for a spool holder until a corresponding mark 9 is reached ( figures 2 and 4 ), then possibly laterally position the transmitter 6 relative to the longitudinal axis of the machine, in cooperation with the passive indexing means 7, 71, without implementation of an active receiver, on a corresponding corresponding reference on said passive indexing means 7, 71, in order to align the light beam which is projected by the transmitter 6 with respect to this passive indexing means 7, 71, to then transmit, by means of said transmitter 6, a beam light of light visible by an operator on the new spool 3 in place on the corresponding spindle of the means 2 spool holder, so as to allow the operator to move the means 2 spool holder laterally to bring the flank of the outer diameter of the coil 3 in coincidence with the light beam projected by the transmitter 6 and to align and prepare the beginning of new band.
  • the positioning of the transmitter 6 is not performed systematically, such positioning is not necessary if the new coil has the same width as the finishing coil.
  • the passive indexing means 7 is constituted by a graduated ruler mounted on the assembly 5 for preparing a new strip to be connected and joining this strip to a finishing strip.
  • the passive indexing means 71 in the form of a mounting bracket of the transmitter 6, this support being provided with positioning marks 71 'corresponding to marks 700' of a strip 700 of checking the position of the new strip of a set 5 for preparing a new band to be connected and joining this band to a finishing band.
  • This support forming the passive indexing means 71 can be made in the form of a guide provided with mark positioning markers or in the form of a guide provided with a digital display means of the position.
  • the loading of the reel 3, for example with a width of 600 mm on the spindle of the means 2 reel holder, can be performed at the corresponding reference 600 mm provided as reference 9 and the positioning of the transmitter 6 will then be performed on the corresponding reference 600 mm provided on the graduated scale forming the passive indexing means 7 ( figure 2 ) and mounted on the assembly 5 for preparing a new band to connect and joining this band to a finishing band and said new band is aligned laterally in coincidence with said light beam visible light emitted by the transmitter 6.
  • the new band is perfectly aligned with respect to the axis of travel of the machine and with the finishing band, so that no longitudinal fold can be created after connection.
  • the emitter 6 can emit a linear beam or a light plane, or two intersecting light planes arranged for example at 90 degrees to one another, so that the resulting trace visible on the periphery of the coil 3 is respectively : a point, a line or a cross.
  • the transmitter 6 may be provided with a prism or dividing mirrors of its light beam. As a result, a part of the latter may be directed on the periphery of the spool 3 and the other part may be directed to the holding area of the beginning of the strip in the assembly 5 for the preparation of a new connecting strip and joining this strip to a finishing strip, passing on a graduated ruler 7 ( figure 2 ) located in this holding zone.
  • the device may comprise two transmitters, one directed towards the coil 3 and the other towards the holding zone of the assembly 5 for preparing a new band to be connected and to join this band to a band, these transmitters being integral with each other.
  • the emitter 6 is preferably selected from the family of laser diodes, but any other strongly convergent light source may be used.
  • the unwinding machine described in connection with the present invention is symmetrical to allow the new spool 3 to be located to the right or to the left of the vertical center axis of the machine. Indeed, when the reel 3 being rewound is placed to the right with respect to the median vertical axis of the machine, then a new reel 3 is placed to the left of this axis and the end of the strip of this new reel is prepared and placed in the holding zone to the left of this axis, in the assembly 5 for preparing a new band to be connected and joining this band to a finishing band. Then, when the unwinding reel 3 arrives at the end of the tape, the finishing tape is connected with the new tape.
  • the accumulator or tape accumulation device 4 placed above the unwinding machine and whose role is to accumulate a sufficient length of tape, before making the connection.
  • the speed of the unwinding machine is temporarily increased with respect to the speed of the downstream machine, so that the excess length produced can be accumulated between the cylinders of the accumulator.
  • the connection operation which requires the stopping of the tape running at the connection area.
  • the downstream machine is fed by the extra length of band available in the accumulator 4, which empties progressively.
  • the new coil placed to the left of the middle axis is unrolled instead of the old one ( figure 1 ).
  • the old coil 3 on the right which is empty or almost empty, is evacuated and replaced by a new coil 3 located this time on the right.
  • the operator of the machine will proceed to the correct positioning of the new band of this coil 3 by means of the positioning device according to the invention, simply by a visual control of the position of the visible light beam emitted by the transmitter 6, in combination with the medium passive indexing 7 or 71, without implementation of a verification means such as a sensor.
  • the operations will follow one another in this way by alternately using the right and left positioning devices of the machine.
  • This device makes it possible to ensure perfect angular positioning between the moving web and the web in preparation. However, there may still be a slight lateral misalignment, due to a lateral defect on the reel being scrolled.
  • a lateral guide device 8 ( figure 3 ).
  • This lateral guiding device 8 is disposed downstream of the connection zone of the assembly 5 for preparing a new band to be connected and joining this band to a finishing band and slaving the lateral position of the band being formed. scrolling with respect to the longitudinal axis of the machine.
  • the lateral guiding device 8 is advantageously in the form of a means for controlling the lateral position of the strip with respect to the longitudinal axis of the machine informing a central unit of the position side of the strip and which consists of a set of two optical cells 8 ', 8 "arranged next to each other near an edge of the strip and slightly spaced laterally with respect to the longitudinal axis
  • This device 8 may be arranged on the left side of the strip, when an observer observes the machine to unroll from the front, the downstream machine being arranged in extension of the strip.
  • the correct position of the band is obtained when only one of the cells 8 ', 8 "is activated
  • the band is moving laterally to the left, seen in the direction of travel, and it is then necessary to move the coil 3 correspondingly running by means of its trolley 2 reel holder to the right, in order to refocus the band scrolling.
  • the displacement of the carriages 2 reel carriers is carried transversely to the longitudinal axis of the machine to unwind by means of electric motors, in a manner known per se and is not described in detail.
  • the reel carriage is moved in such a way that the moving web is automatically re-centered.
