Definitions

  • the present invention relates to the field of machines for unwinding strip materials from reels, for feeding, in particular, in particular continuously, printing machines, cutters, folder-gluers, or other machines for shaping, and relates to a machine to unroll.
  • the existing unrolling machines intended for supplying the aforementioned machines, are generally ill-suited to supplying said machines due to their size and their relatively large weight, which do not allow installation in multi-storey buildings. fitted with relatively low freight elevators and whose ceiling heights are also often relatively low.
  • the reels are almost always loaded by moving the centering heads or pins in an arc, because these heads or pins are mounted, either at the end of a pivoting arm , or on a turntable.
  • the axis of the coil moves in a horizontal and / or vertical plane, which requires, for the introduction of the heads or spindles, tedious successive displacements of each of the two elements, alternatively, these displacements having to be controlled by the machine operator, until the axes of the heads or spindles and the spool coincide.
  • Unwinding machines are also known in which the connection of the finishing strip of a reel with the beginning of the strip of the following reel is carried out during a temporary stop, the finishing strip passing through a reserve of strip disposed between the outlet of the unrolling machine and the processing machine located downstream.
  • the present invention aims to overcome these drawbacks.
  • Its purpose is, in fact, to be a machine for unwinding, characterized in that it is essentially constituted by two reel-carrying towers capped at their upper part by a bridge structure for receiving a strip accumulator and by two boxes for connecting strips when stationary, each assigned to a spool holder tower and mounted movable in translation, transversely to the strip under the bridge structure.
  • the unrolling machine is essentially constituted by two reel-holder towers 1 capped at their upper part by a structure in bridge 2 for receiving an accumulator 3 of bands and by two boxes 4 for connecting bands when stopped.
  • the boxes 4 are each assigned to a reel holder tower 1 and are mounted movable in translation, transversely to the strip under the bridge structure 2.
  • Each reel holder tower 1 is constituted by a frame 5 for connection to the bridge structure 2, and by a movable frame 6 movably mounted on the frame 5 perpendicular to the bridge structure 2, this frame 6 carrying, in addition , a means 7 for vertical displacement of the spindle 8, mounted in cantilever, to be inserted in the coil 9 to be unwound, and being connected in translation to the corresponding box 4 ( Figures 1, 4, 5 and 6).
  • the mobile frame 6 is guided on the frame 5 is produced either by means of rails or by rolling on the foundation plate of said frame 5, and its transverse movement is controlled by a jack, by a pinion and rack assembly, or similar.
  • the mounting of the movable frame 6 on the frame 5 allows said frame 6 to be displaced from its normal position for unwinding the reels to a loading position, so as to introduce the spindle 8 into the mandrel of the reel 9 and loading the latter.
  • the means 7 for vertical displacement of the spindle 8 mounted in cantilever is constituted in the form of a support cage for the spindle 8, housing the axial drive mechanism of the latter by a current motor regulated by a variator of the four quadrant type, and guided on rails 10 of the front face of the movable frame 6 by means of pads 11, or by means of guide slides, the spindle 8 passing through a vertical slot 12 of said front face of the chassis 6, and by a mechanism 13 for vertical displacement of the means 7, in the form of a screw, rack, chain, or other lifting mechanism, actuated by a motor, by a jack, or manually.
  • the machine according to the invention is, moreover, equipped, in front of the frames 5, with a guide rail 14 for a motorized carriage (not shown) for handling coils whose stop positions in front of the vertical axis of the pins 8 of the reel-holder turns 1 are provided automatically, in a known manner, by latches and position detectors.
  • each movable frame 6 of the reel-holder towers 1 is provided with a device for detecting the diameter of the reels, mechanical, of the probe type, with electromagnetic waves, of the radar type, or in the form of a photoelectric detector, which is connected, in a known manner, to a computer controlling the mechanism 13 for vertical displacement of the means 7.
  • a device for detecting the diameter of the reels mechanical, of the probe type, with electromagnetic waves, of the radar type, or in the form of a photoelectric detector
  • This embodiment allows complete automation of the loading of the coils, because the said coils can be stopped precisely in front of the axis of the spindle 8, then loaded by automatic movement of the mobile chassis 6.
  • the mechanism 13 is advantageously connected, at its anchoring point on the chassis 6 or on the means 7, to a strain gauge (not shown), this gauge being able to advantageously be connected to a stock management computer.
  • a strain gauge not shown
  • This embodiment makes it possible to carry out a very precise weighing of the reel after its loading on the spindle 8, so that the acquired tion of a special weighing scale, bulky and expensive, generally housed in the ground in front of the unrolling machine, is no longer necessary.
  • the forecast of a strain gauge allows to proceed to successive weight recordings which can be recorded by a paper consumption management computer and taking into account the weight of the raw reel arriving from stock, then that of the coil removed from the outer turns damaged during transport and, finally, the weight of the coil at the end of the unwinding operation.
  • each coil change can be carried out by simply sending an order to move the turn 1 to provide a reel to its loading position, the machine then monitoring operations until the reel 9 is brought to the spindle 8 in its unwinding position, the transverse movement device for each movable frame 6 allowing, moreover, to ensure lateral position corrections of the unwinding reel 9.
  • the mobile chassis 6 is advantageously provided, at the vertical slot 12 for passage of the spindle 8, with a means for blocking in the vertical position the guide sleeve of the spindle 8, in the form of locks cooperating with notches of said sleeve, clamping jaws, acting laterally on said sleeve, or other devices for securing in position.
  • connection boxes 4 are mounted in opposition, each under the bridge structure 2 movable transversely relative to the latter, by means of horizontal slides 15 integral with said structure 2 and projecting forward relative to the latter, and are secured in translation each with the corresponding tower 1 ( Figure 3). Due to this arrangement, each box 4 follows all the movements of the corresponding tower 1 and protrudes towards the side of the conductor to facilitate access to it, each box 4 being linked to its corresponding coil holder tower 1 in such a way that 'they always move together.
  • each box 4 has a plate 16 provided, on the one hand, with a transverse slot 17 inclined relative to the horizontal in which is mounted, movable by means of a jack or '' a linear motor, a cutting device 18, and, on the other hand, several rows of air suction holes 19, or pliers, these holes 19 or pliers being arranged, on the one hand, on the other and on the other of the slot 17 and, on the other hand, parallel to the lower edge of the plate 16 which is, on the other hand, constituted by three planes forming an obtuse angle between them, the central plane containing the inclined transverse slot 17, and, on the other hand, mounted along one of its horizontal edges, preferably along its lower edge, pivotally, on the box 4, the pivot axis 20 of the plate 16 simultaneously forming the support for return cylinders 21 of the strip to be unwound.
  • the boxes 4 advantageously have a width greater than the greatest possible width of strips to be unrolled and their plate 16 has, on either side of its useful surface corresponding to the maximum width of strip to be unrolled, a recessed surface allowing arrange the command and control instruments 22, as well as a means 23 for protecting the cutting device 18 in the rest position, in the form of a cover.
  • the plates 16 of the boxes 4 are, on the one hand, symmetrical with respect to a vertical plane passing between the boxes 4 and, on the other hand, each loaded on its inner face by a pivoting device about the axis 20 such as a jack, a cam, or the like.
  • each plate 16 has the effect of causing said plates 16 to pivot about their axis 20, and of producing an intimate application of the central planes containing the transverse slots 17 of said plates 16 with the interposition of finishing and new strips, as well as their adhesive butt-joint bonding.
  • each plate 16 is provided, on its central plane containing the inclined transverse slot 17, with a groove 24 extending parallel to said slot 17 at a distance at least equal to the width a double-sided adhesive joint connecting the finishing and new strips.
  • the driver then performs, at eye level, the attachment of the end of the strip by suction to the plate 16 of the casing 4, the actuation of the suction device, connected to the plate 16 behind the suction holes 19, being carried out in a known manner by means of a pushbutton.
  • the start of the strip is then cut at an angle, either manually by guiding a knife into the transverse slot 17, or automatically by means of the cutting device 18, and the excess strip is removed.
  • the suction at the holes 19 surrounding the slot 17 is then cut so as to allow the partial removal of the strip end of the plate 16 in order to carry out the laying along the axis of the slot 17 of an adhesive seal.
  • the strip end is applied to the plate and partially to the joint for the future butt connection.
  • the strip of the new coil is thus ready to be connected, and the order to return to the unwinding position of the tower 1 and its box 4 can be given.
  • the coil will be kept locked in rotation by a small locking brake known per se.
  • the lateral positioning of tower 1 with its coil can be adjusted as indicated above, and synchronous lateral movements of the two towers can be performed automatically while maintaining lateral alignment of the coils and perfect coincidence of caisson slots 4.
  • the rails 15 for guiding the boxes 4 can also extend parallel to the transverse slots 17 inclined relative to the horizontal. So the two opposite slots 17 of the boxes 4 always slide one opposite the other and in alignment, whatever the respective positions of the towers 1, therefore even when the boxes 4 move separately.
  • the order of connection of the new reel is given, either by an automaton, or by an audible and / or luminous alarm warning the operator.
  • the strip accumulator 3 is normally filled, so that the finishing reel can be braked until it comes to a complete stop by means of the brake motor actuating its support pin 8.
  • the suction device connected to the holes 19 of the plate 16 of the corresponding box 4, is then placed under vacuum and the cutting device 18 of this box 4 is actuated simultaneously, so that the finishing strip is cut at an angle, then the rest of the strip connected to the finishing reel is automatically removed from the plate 16, after cutting off the suction at the holes in the lower part of the said plate, by reverse rotation of the axial unwinding motor.
  • the machine can be provided with at least one removable cutting counter-bar (not shown) applying the strip on the plate 16 along the cutting slot 17 of each box 4 , indifferently, this cutting counterpart bar being maneuvered into the release position by means of a pair of pneumatic cylinders after the passage of the knife 18, one of these jacks serving to move the bar in front of the box 4 and the other to its application against the plate 16 of the box with tightening of the strip to be cut, this second jack can be a rotary jack or a double-acting jack pivoting the bar towards one or the other box 4.
  • This embodiment allows maintenance perfect tape, flat on the plate 16 and obtaining a clean cut, even with slightly rigid materials.
  • the plates 16 of the boxes 4 are then pushed towards one another by pivoting about their axis 20, until the tail of the ending strip comes to stick on the adhesive seal at the end of the strip of the new reel .
  • This movement of the plates 16 takes place very quickly, and in fact only corresponds to a pulse producing the bonding pressure of the ends of the strip, triggers, at the end of the pulse, the cut off of the suction through the holes 19 and, simultaneously, the starting of the axial unwinding motor of the new coil. The latter is accelerated in rotation until its normal working speed is obtained, and the paper accumulator 3 can be recharged.
  • the motors fitted to the towers 1, intended for the axial drive of the spindles 8, are advantageously, in known manner, DC motors sufficiently powerful to allow rapid acceleration and deceleration of the coils in order to avoid oversizing of the reserve belt variation 3.
  • the power variation of these motors is subject to the permanent control of two variables, namely the belt speed of the machine fed downstream by the unwinding machine, and the prescribed belt tension is continuously measured at various places. All of these variables and parameters can be managed, in a known manner, by a computer which harmonizes and ensures a band flow at constant voltage despite possible changes in production speed or the operations of connecting the reel when stopped, which use the back-and-forth of the tape accumulator 3.
  • the position of the mobile trolley of the accumulator 3 is continuously regulated by means of a special motor, the anchoring of the mechanical socket of which is connected to a force measuring element placed on the mobile trolley.
  • This force measuring element can also be mounted on a guide roller placed at the exit of the carriage so as to continuously monitor the tension of the belt, which must remain constant thanks to the combined action of the mobile carriage and the spindle unwinding motor.
  • the unrolling machine can be provided with a marking device (not shown) advantageously placed at the level of the casing 4 close to the fixed part of the accumulator 3, above of the inclined transverse slot 17 on the plate 16, or on the upper face of this box, or even at the entrance to the accumulator 3, this marking device being a mechanical perforation or other device, or a deposit device or inkjet controlled with the same periodicity as the strip shaping located downstream, and being disposed at a distance from the plane containing the inclined slot 17 equal to a fraction of a step of the processing machine located downstream.

  • a fraction of a step will advantageously correspond to a distance such that the joint between strips is automatically located on a part of the envelope having no marking or cutting. This process makes it possible to neutralize the elasticity phenomena of the strip which are harmful to precise location of the connector.
  • the unrolling machine can be provided with support arms for the cantilevered end of the pins 8, these arms being either mounted on the chassis 6 of the towers 1, retractable, and with the possibility of telescopic extension and retraction in correspondence with the downward and upward movement of the vertical displacement means 7, or mounted on the frames 5 so retractable, and movable in translation together with the chassis 6 or by means of its own control means actuated simultaneously and in an identical manner to the translation device of said chassis 6.
