Definitions

  • This invention relates to a device for cutting a moving web of sheet material without interrupting the material's travel along its defined path.
  • the device is intended for use in web winding equipment in which the web is wound into rolls on successive cylindrical cores, the web being cut at the stage at which one core becomes fully laden and the web feed must be transferred to an empty core. It is particularly concerned with cutting a fast-moving web without reducing the web speed.
  • the invention is especially suitable for the cutting of webs of photographic film stock and is primarily described herein with reference to this duty.
  • the main application in this field is in the rewinding of large rolls of film stock, typically after coating with photosensitive material.
  • the web emerges from the coating line at high speed and is taken up on a driven core, creating a roll of wound material.
  • the invention is not limited to this particular application, and is usable in general for the cutting of plastics material and paper webs.
  • a typical automated arrangement for web rewinding comprises a turret including a rotatable holder for two cores. Winding commences on a first empty core and continues until a full roll has been wound. As the winding approaches the full -roll stage the holder moves a second empty core towards and close to, but still out of contact with, the path of travel of the web upstream of the filling core. When the latter core is fully wound the web is cut close to the empty core. The new leading edge of the web is brought into contact with the empty core to be taken up thereon.
  • Application to the new core is normally achieved with the assistance of a pre-applied adhesive strip on the core surface and a pressure roller which pushes the newly cut leading edge into contact with the adhesive strip.
  • the holder is then rotated to turn the full core away from the machine, and the full core is then removed from the holder and replaced by a new empty core. The holder can again be rotated at the required stage to bring a new empty core close to the web.
  • a drive means for the blade which comprises a motor, preferably an air motor, carried on a casing which is driven across the web by a pneumatic cylinder.
  • a motor preferably an air motor
  • Other prior proposals for example Swiss patent specification 567999, have suggested the use of a carriage to pass a fixed blade across the web.
  • a further advantage of lightweight carriage construction is that the carriage can be accelerated in a short lateral distance to a speed sufficient to permit the cutting of a high speed web.
  • a web cutting device which comprises a frame extending across the path of the web and a movable carriage on which is mounted a rotary cutting blade, wherein the frame includes a fixed track for the carriage, characterised in that the frame further carries a fixed driving bar parallel to the carriage track and one or more fixed motors with an associated drive belt to move the carriage, the carriage incorporates a drive wheel rotatable by contact with the fixed driving bar to drive the cutting blade and in that the fixed carriage track, the fixed driving bar and the drive belt all extend beyond the edges of the web path.
  • the invention offers the advantage that the bulk of the components required to drive the cutting blade are accommodated on the frame, since the fixed motor(s) provide a dual-purpose power source serving both to move the carriage and rotate the cutting blade.
  • This dual-purpose power source allows the carriage to be of simple and lightweight construction such that it can be accelerated from rest to the desired cutting speed within a portion of the frame extending beyond the edge of the web, i.e. before the blade contacts the web.
  • the blade thus traverses the web uniformly at the desired cutting speed and is then retarded to rest after the cut is complete, the retardation being also accomplished within a portion of the frame beyond the edge of the web. Uniform cutting speed across the web is an important factor in achieving a clean cut.
  • the dual-purpose power source further ensures that the rotational speed of the cutting blade is proportional to the carriage traverse speed. This permits the use of predetermined and preset driving ratios between the traverse and blade speed to give optimum cutting.
  • a further advantage of lightweight carriage construction is that the carriage can be accelerated in a short lateral distance to a speed sufficient to permit the cutting of a high speed web. Because of the limited space available in a typical film coating line between the rest and cutting positions the acceleration, and retardation, of the carriage in the available space needs to very high.
  • the available space may for the acceleration and retardation at the sides of the web may be as little as 300 to 400 mm, requiring acceleration and retardation forces of up to 15G.
  • the invention permits these levels of acceleration and retardation to be achieved and withstood and thus obviates the previous need to slow down a high speed web before making the cut. As a result it is also possible to avoid the need for an accumulator in the web coating line.
  • the rotary cutting blade preferably has an associated mounting plate, which rotates with the blade and which provides a convenient support to hold the blade and to permit easy attachment of replacement blades.
  • the mounting plate is preferably attached to the carriage in such a manner, for example through a universal joint, that the angle the blade presents to the web is adjustable.
  • the carriage preferably also includes a cutting knife, fixed relative to the carriage, to cooperate with the rotary blade to ensure a clean cut of the web.
  • the cutting edge of the rotary blade is polygonal rather than simply circular. The polygonal edge cooperates with the cutting knife so as to apply a slight scissor-action to the cut.
  • a spring member for example a conical disc spring, is preferably interposed between the rotary blade and its mounting plate so as to ensure that the respective surfaces of the web are firmly contacted by the rotary blade and the fixed knife throughout the cutting action.
  • the spring member is of a configuration which applies its greatest pressure at the point where the rotary blade bears against the knife.
  • the rate of rotation of the cutting blade is preferably such as to give a peripheral blade speed of about 1.5 to 2.5 times the web speed. This is found to be advantageous in ensuring a clean cut of the web, and it also increases the life-time of the cutting blade.
  • the cutting blade and cutting knife are preferably of high quality steel.
  • the carriage track is disposed at right angles to the direction of travel of the web.
  • the web is thereby cut on the slant, which has the advantage that the leading edge of the cut web presents an angled tip which can readily be taken up on a new core.
  • the angle of cut is selected by the relative velocities of the web and the cutting blade. Since the web speed is normally set by other factors the angle is effectively set by, and can be adjusted by, the cutting speed.
  • the angle is normally selected according to the diameter of the core so that the angled portion of the web is taken up in a single rotation of the core (which means an angle of about 60 o between the side edge and leading edge of the web at the leading point of the severed edge). This configuration assists in keeping the wound surface of the web as smooth as possible.
  • the preferred configuration for the track is two spaced-apart bars, each of circular cross section, extending across and beyond the web and being secured at their ends to the frame.
  • the carriage preferably employs running wheels with circumferential grooves to engage the bars.
  • the preferred number of wheels is three, two running on one of the bars and one on the other bar.
  • This three-wheel arrangement has the advantage of combining light weight with stability.
  • the single wheel on the other bar can conveniently incorporate adjustment means so as to ensure a proper engagement of the wheels with the bars.
  • the drive belt for the carriage is an endless loop extending across and beyond the full width of the web so as to power the carriage on the cutting pass from rest to the cutting speed, retard it to rest and subsequently to return the carriage to the initial rest position.
  • the carriage should be securely attached to the belt so as to avoid the possibility of slippage relative to the belt since this could mean that the desired cutting speed might not be achieved for the whole of the cut.
  • a preferred means of ensuring no slippage is to employ a drive belt with transverse teeth on one side, i.e. a so-called timing belt, and to provide corresponding notches on the carriage to engage the ribs.
  • the carriage preferably further includes a clamp to hold it securely to the belt.
  • One advantageous form of clamp for this duty is described and claimed in our copending European patent application entitled "Clamping device" filed on even date herewith. By these means it is possible to for the carriage and its drive to withstand the huge acceleration and retardation forces between rest and the cutting speed.
  • the transverse distance between the starting rest position of the carriage and the initial cutting point is preferably slightly greater than the distance over which the carriage acceleration occurs. This is because in practice it is found that the momentum of the carriage at the end of the acceleration causes a slight increase in carriage speed over the cutting speed ("overshoot"), which can be detected as a short peak in the carriage speed profile, before the carriage settles at the cutting speed.
  • the transverse distance provided for the retardation to the end rest position is also preferably greater than the acceleration distance in order to foresee a free run-out path without mechanical stops.
  • the fixed motor or motors used to power the drive belt are preferably DC motors. Their preferred location is at the side of the frame beyond the edges of the web. The most preferred arrangement is to employ two motors, one either side of the frame. This assists in giving a positive drive to the carriage which permits the degree of acceleration necessary to bring the carriage up to the cutting speed in the available space beyond the web. Moreover the sophisticated control that is desirable to ensure a precise and uniform cutting speed across the web width can be applied to the fixed motor(s) without adding to the weight of the carriage.
  • the fixed motor or motors serve both to provide the power to move the carriage across the web and to rotate the cutter blade.
  • the drive to the cutter blade is provided by the combination of the driving wheel on the carriage and the fixed driving bar on the frame. Although in principle the contact between these components can be simply through friction, in which case the carriage track can act as the driving bar, it is much preferred for the fixed bar and the driving wheel to be respectively a rack and pinion.
  • the drive preferably includes a second pinion so that the tip of the cutting blade rotates in the same direction as the direction of movement of the carriage.
  • the drive preferably further includes an adjustable joint so that the angle of the cutting blade can be adjusted relative to the carriage. The angle is determined with reference to the web and cutting speeds and having been adjusted to a position for a particular duty is then fixed in that position.
  • the frame on which the carriage is mounted is preferably supported by one or more swivel arms, most conveniently powered by pistons, which can move the carriage into position for the cut and swing it away again after the cut is made.
  • the carriage can be returned to its start position on the transverse track after the frame has been moved away from the web.
  • the frame also includes one or more guide rollers extending across the width of the web and which maintain the web at a small distance from the new core immediately prior to the cut. It is also required for the frame to carry one or more smaller pressure rollers, typically powered by a spring and retractable by a pneumatic piston, which, as mentioned above, are employed to press upon the newly cut leading edge of the web as it reaches the core surface and thereby assist in securing the leading edge to an adhesive on the core.
  • the pressure rollers may be carried on a support which is movable towards and away from the winding core by a triggerable mechanism, the mechanism being triggered by a pin carried by the carriage.
  • the mechanism preferably includes a slidably mounted inertia block which acts to reduce the tendency of the pressure rollers to bounce when applied to the web core.
  • the illustrated rewinding turret comprises a support structure 2 (indicated by dotted lines) which carries a centrally pivoted holder 4 (also indicated by dotted lines) with winding cores 20 and 22 at the ends remote from its pivot point.
  • the cores are driven by motors (not shown).
  • the turret receives web material 10 from a photographic coating line (not shown) which passes over guide rollers 12, 14 and 36 to reach the respective winding core.
  • the support 2 also carries an axle 32 on which is mounted a frame 30, powered by pneumatic pistons 34 which move it between an idle position (indicated by dotted lines 30' in Figure 2) and a web-cutting position (shown by continuous lines 30). During most of the winding operation the frame rests in the idle position. The continuous lines thus show the frame 30 in position at the point of time at which a full roll 23 has been wound on the core 20 and the web is about to be cut and secured to the empty core 22.
  • the frame 30 carries a guide roller 36, with an associated drive motor 37.
  • the frame 30 also carries a spacer 19 which abuts against a sleeve 18 on the winding core and in that way determines the exact position of the guide roller 36. In the web-cutting position the guide roller 36 bears against the web 10 to hold it close to the empty core 22 across the full web width.
  • the frame 30 also carries a transverse beam 40 which comprises cylindrical guide bars 41 and 42 for a movable carriage 50.
  • Drive motors 43 one at each end of the beam 40, power an endless loop toothed drive belt 44 to which the carriage 50 is firmly clamped.
  • a fixed bar 45, including a toothed rack 46 is also attached to and extends across the full width of the frame 30.
  • the carriage 50 has a base plate 51 to which two upper pulleys 52 and a lower pulley 53 are rotatably mounted.
  • the pulleys each having a reinforced nylon outer portion mounted on ball bearings, run on respectively the upper and lower guide bars 41 and 42.
  • Each reinforced nylon outer portion carries a circumferential bar groove 52a, 53a, having a generally curved cross-section with a radius smaller than that of that curved wheel engaging surface of the guide bars 41 and 42 which is engaged by the wheel.
  • the lower pulley 53 incorporates adjustment means to allow the carriage 50 to be held on the guide bars in a secure but free-running condition.
  • a side arm 54 from the base plate 51 carries a nylon pinion 56 mounted on a ball-bearing-mounted axle 55 and a steel pinion 58 mounted for uni-directional rotation on ball-bearing-mounted axle 57.
  • Axle 57 is connected through a universal joint 59 to a drive axle 61 in a cutting head 60.
  • the uni-directional mounting of pinion 58 serves to prolong the cutting life of the blade.
  • the pinion 56 engages the rack 46, rotates as the carriage 50 moves across the frame 30 and thus rotates pinion 58, thereby transmitting the drive to the cutting head 60.
  • the pre-cutting rest position of the carriage 50 is indicated in Figure 1 by the line R1 and the post-cutting rest position by the line R2.
  • Lines R1 and R2 thus show the path of the carriage 50 from rest to rest and highlight the relative short lateral distances between R1 and R2 and the respective edges of the web 10 in which the carriage 50 must be accelerated to, and retarded from, the required cutting speed.
  • the cutting head 60 ( Figure 4) has a mounting plate 62 in which the axle 61 is held by bearings 63 and pressure discs 64.
  • a blade holder 65 attached to the axle 61 carries a rotary blade 66 which is resiliently held in place by disc springs 67 and backing ring 68. The blade 66 is pushed against the counter knife 71 by the disc springs 67.
  • the amount of pressure can be set by means of the collar 72 and a differential screw 73.
  • the mounting plate 62 further carries a curved guide plate 70, concentric with the core, to conduct the freshly cut web tip towards the core.
  • An adjustable security plate 69 on the blade holder 65 further ensures that the disc springs 67 stay on the blade holder 65.
  • the carriage 50 is triggered to make its web-cutting pass. It accelerates from position R1 to its cutting speed, carries the cutting head 60 across the web uniformly at the said speed and then is retarded to rest at R2.
  • the speed profile of the carriage 50 from rest to rest is controlled by the motors 43 and relayed to the carriage 50 through the drive belt 44.
  • the engaging rack and pinion 46 and 56 transmit the drive to the rotary cutting blade 66.
  • the cutting is thus also achieved at a uniform peripheral speed of the blade 66 which is proportional the carriage speed.
  • the frame 30 With the cut complete the frame 30 is swung away from the cutting position and returned to the idle position 30'. The carriage is then returned to its start position R1 ready for the next cutting pass.
  • the fully wound roll 23 can now be removed from the core holder 4 and replaced by a new empty core which will in turn be used to replace the core 22 when it is fully wound.
  • These features include the additional fixed knife, non-circular shape for the rotary blade, spring-loaded mounting for the rotary blade, adjustable cutting angle, the stable cutting base provided by the twin-guide bar/three mounting wheels of the carriage and the rack and pinion drive to the rotary blade.
  • a pressure system for urging a cut web tip onto adhesive tape applied to an empty winding core 22 comprises a pair of pressure rollers 82, 84 carried on a hinged roller support 86, which is movable towards and away from the winding core 22 by a pressure roller system 88, mounted on the machine frame 20.
  • the pressure roller system 88 includes a support 90 secured to the machine frame and carrying a double acting pneumatic cylinder 92.
  • the double acting cylinder includes a piston rod carrying a nut 94.
  • a compression spring 96 urges a boss 98 against an arm 100.
  • An inertia block 102, integral with the arm 100, includes a guide slot 104 through which a key 106 passes.
  • the double acting cylinder 92 is activated so that the piston rod with nut 94 comes free from the top of the arm 100.
  • the pressure roller system 88 is mounted on the machine frame and is triggered by a pin 108 of the carriage 50 as the carriage reaches the trigger lever 110. Pivoting of the lever 110, as seen in Figure 7 causes the upper part thereof no longer to be held by the roller 112 so that the pressure mechanism is released and springs upwardly (in the orientation of Figure 6), urging the tip of the cut material 10 onto the web core 22. Pivoting of the arm 110 by the pin 108 triggers the complete mechanism which is pushed upwardly by the spring 96.
  • the freely movable inertia block 102 remains behind.
  • the block 102 continues to move until the end of the slot 104 abuts the key 106 so that the kinetic energy of the rebounding rollers is absorbed and as a result the web tip is firmly applied to the core.
  • the cylinder 92 is then operated to retract, whereby nut 94 engages the arm 100 and lowers the mechanism until the arm 110 can pivot under the roller 112 to arm the mechanism for the next operation.
