Definitions

  • ABSTRACT A web winding and cutting apparatus capable of automatically cutting and coiling relatively short lengths of a material in web form onto a core. Excessive damage of the material at the leading edge of the freshly cut web is avoided because the cutting cycle is very short and because a mechanism provides for immediately tightening the web onto the core, so that slipping of the web cannot occur. Cutting is carried out by a mechanism through sudden release of stored energy and optimum tightening of the web onto the core is obtained by controlling the coefficients of friction between the web and the core at one side and between the web and a pressure roller at the other side.
  • the invention is related to a web winding and cutting apparatus and method and is particularly concerned with winders and cutters used for cutting a web into predetermined lengths and winding same subsequently onto a core in an automatic way.
  • the invention is particularly well-suited for cutting relatively short portions of a web of photographic material and winding them subsequently onto a core without excessive damage caused by grooves and scratches due to either mechanical friction between the web and the core or to fluttering of the web around the latter.
  • web denotes any coilable length of sheet material irrespective of its width or the material of which it is composed.
  • the invention can be used for winding and cutting webs of paper, fabric, high polymeric material or the like, in already coiled form or as a continuous web feeding from a web manufacturing plant.
  • a web is moved through coating and drying stations in succession and wound upon a core in order to obtain a master-roll.
  • the latter may either be spliced, as it is the case for motion picture films, or spliced and cut into formats, as is done for sheet films.
  • Some photographic material is marketed in rolled lengths of only a few meters.
  • the material to be marketed, having already been cut'to the final width is wound onto a core by winding apparatus provided with a cutting mechanism which cuts the material into the required predetermined lengths for the individual coils. This cutting step is carried out semior fully automatically and preferably at a relatively high speed.
  • Present day cutting and winding apparatus generally consist of a device that cuts a web transversally be means of a knife and/or a counter-knife and subse quently guides the freshly cut leading edge of the web towards a core which may either be provided with an adhesive substance or kept in a certain position promoting an easy pick-up" of the leading edge.
  • Other methods of winding consist in conferring to the core a rotational speed corresponding with the feeding speed of the web and subsequently guiding the leading edge of the web into a kind of shell which, in combination with an air stream urging the leading edge ofthe web towards the core, enables a first part of the web to be rapidly wound onto the core which is then transferred to a winding station for the winding on the remainder of the predetermined length of web.
  • the cutting device cuts the web again and the cycle is repeated with a new core, the latter having been brought into stand-by position during the previous winding cycle.
  • a photographic emulsion layer normally a dispersion of silver halide crystals in a gelatinous binder, is very vulnerable to damage by mechanical friction, and the method of engaging the leading edge of the web employed in modern winding machines may cause grooves and scratches, at least and especially at the beginning of a winding cycle since during the winding on of the first convolutions the material tend to flutter on the core.
  • Cutting and winding machines which use cores provided with adhesives show the inconvenience that most of the said adhesives are chemical incompatibile with the emulsion layer.
  • Another aim of the invention is to provide a method and a machine in which the above mentioned drawbacks are obviated at least to a substantial extent. Another aim is to provide an automatic, high speed winding apparatus for winding short web portions without excessive loss of material.
  • the present invention provides a web winding and cutting apparatus comprising a holder which is adapted to be loaded with empty cores and is movable for bringing said cores successively to a web pick-up and winding station at which windingon of a least part of a predetermined length of web coming from a web supply station takes place.
  • the core holder Prior to the completion of windingon of such predetermined length of web onto a core, the core holder is displaced to move that core to another position and to bring an empty core into position for receiving the new leading edge of the supplied web which will be formed when the web length presently being wound onto a core is severed from the following length of web.
  • Web guiding means which moves into operative position in relation to an empty core after its arrival at the winding station ready for guiding the new leading edge of the web around the empty core.
  • a web severing mechanism is provided which severs the predetermined length of web from the following length of web at a position adjacent the pick-up and winding station and while the following part of the web is clamped against the empty core on which it is to be wound.
  • the said severing mechanism is constructed so that the web severing movement takes place rapidly under energy stored in the said mechanism.
  • the mechanism may comprise a compression spring which bears against an arm carrya ing a web severing knife and which is placed in compression by another part of the mechanism prior to the moment at which the web is to be severed.
  • the web guiding means comprises a shell which cooperates with an empty core to define a guide passage for the web, and a web-tightening roller which frictionally engages a web portion as it emerges from said guide passage and tightens the web portion around the core.
  • the web severing knife may be carried by a first arm and the shell and web-tightening roller may be carried by a second arm, the two arms being mounted for approach displacement towards an empty reel at the pickup and winding station, from opposite sides thereof.
  • the second arm may also carry a counter-knife so that the web is cut or sheared between the knife and counter-knife.
  • the invention includes web winding and cutting apparatus comprising:
  • c. means to confer a predetermined rotational speed to the cores
  • cutting means for cutting the web after a predetermined length of said web has been wound onto said core, said cutting means comprising a knife mounted on a first arm, which is driven by motor means with application of means for accumulating and for suddenly freeing stored energy, and a counter-knife mounted on a second arm,
  • guide means for guiding the leading edge of the web onto the empty core
  • the guide means comprising a guide shell for encircling the empty core, at least one idler roller capable of rotating against the web before, during and after cutting and at least one slippingly dirven roller for urging the web towards the core after cutting, the circumferential speed of the slippingly driven roller exceeding the circumferential speed of said empty core, wherein the coefficient of friction of the material, from which the slippingly driven roller is made relative to the web is greater than the coefficient of friction of said empty core relative to the web, and

  • FIG. 4 presents the cutting mechanism of FIG. 1, immediately after the cutting cycle.
  • FIG. 5 is a diagrammatic view of a winding and cut-.
  • FIG. 1 there is shown a cutting mechanism during the winding up step of a web 1 onto a core 2.
  • the core 2 is positioned on a turret 4, here represented by a circle, together with an empty core 3.
  • the turret 4 may be driven stepwise after each winding cycle in order to bring a new core in winding position.
  • a cutting mechanism mainly comprising two arms, 5 and 13, both pivotally journalled on a shaft 33 on which the cutting and guiding devices for the web are provided.
  • the knife 17 and the rollers 16 and 18, roller 16 being separately mounted on the arm 14 and elastically supported by means of a spring 15.
  • a dash-pot 35 in which two springs, 20 and 21, are housed with their mutually adjacent ends bearing against the piston 36 at the end of the piston rod of air-motor 19.
  • Arm 13 carries an extension crank 25 at its extremity which, upon rotation contacts a pawl 26, which is able to move longitudinally under action of air-motor 27.
  • the arm 13 is also provided at its pivoted end with teeth 24, which after a certain pivotal motion of the arms 13 about shaft 33 engage with the toothed end of lever 23, which is pivotally connected to the arm of air-motor 22.
  • FIG. 2 presents the cutting mechanism in standby position, immediately before the cutting cycle.
  • the core 2 having nearly attained its final diameter has moved over whereas the empty core 3 which is slippingly driven by a motor (not shown) is placed between the arms 5 and 13, by half a revolution of the turret 4 and starts rotating so that its circumferential speed is equalto the speed of the moving web.
  • Arm 5 has already reached its position for cutting and the guide shell 6 lies in close proximity to the empty core 3.
  • air-motor 9 urges roller 10 against the empty core 3, so that the latter becomes surrrounded over about three quarters of its circumfer ence.
  • arm 13 is temporarily maintained in stand-by position, due to the fact that upon its rotation about shaft 33, its movement is arrested at a given moment because the extension crank 25 is stopped by pawl 26.
  • FIG. 3 is shown the cutting cycle, once a sufficient amount of web has been wound upon the core 2.
  • the extension crank 25 is released by the pawl 26 due to retraction of the piston of air motor 27, and the energy, accumulated in the spring 20 is suddenly freed, so that arm 13 is rapidly swung further upwardly by the expansion of spring 20 (which has a greater compliance than that of spring 21) so that the knife 17 is driven through the web.
  • the roller 16 resiliently presses the web 1 against the core 3 immediately behind the line of the cut.
  • roller 18 provided at the end of arm 13 trailing cutoff end of the web as it travels towards the core 2, so avoiding an occasional fluttering of that end against machine parts.
  • spring 21 has become compressed, whereas spring 20 is released. The whole cycle is carried out in a few hundredths of a second.
  • FIG. 4 the situation immediately after the cutting stage is illustrated.
  • air-motor 22 is energized and causes the toothed end of lever 23 to interlock with the teeth 24 on arm 13.
  • the arm 13 is maintained in a projected position, guaranteeing optimum contact between the web and the rollers while occasional vibrations of the arm are completely prevented.
  • the knife 17 has already been withdrawn, but by the expansion of the spring 15 roller 16 remains in biased position against the core 3.
  • the leading edge of the web is guided in the space defined by the guide shell 6 and the core 3.
  • roller 16 By the fact that frictional contact occurs first between the web 1 and the roller 16 just prior to cutting and that at the instant of cutting, roller 16, web 1 and core 3 are firmly urged toward each other under influence of spring 15 which becomes compressed, the web 1 further advances in the space formed by the guide shell and the core. Because no difference in speed between the web 1 and the core 3 exists, the leading end of web 1 may flutter during the period that it advances from the knife upto roller 10, as no tightening action occurs.
  • Roller is slippingly driven in such a way that when not contacting core 3 its circumferential speed is higher than that of the core 3.
  • Roller 10 consists of or is provided with a layer of a material which has a higher frictional coefficient with the web material than does the core 3.
  • the roller 10 is made of or coated with rubber.
  • FIG. 5 gives a diagrammatic view of a complete winding apparatus embodying the invention.
  • web 1 is fed to a core 2 by passing over guide rollers 30, a tension regulating device, consisting of a weight 32 and a dancer-roller 31, and the cutting device formed by the arms 5 and 13.
  • a number of empty cores 39 lying on an inclined plane 40, are prepared to be fed to a cradle 4-1, mounted at the extremity of the arm of air-motor 37.
  • a turret 38 provided at its extremity with a fork 42, carries an empty roller to turret 4 when air-motor 37 becomes energized.
  • the other extremity of turret 38 may be provided with a member suited to receive finished rollers, which may be forwarded to a packing station (not shown) for example.
  • the operation of the device is as follows (FIG. 5).
  • the web 1 is wound onto core 2 which is in operating position.
  • the turret 4 starts revolving over a given angle in this case 180 in order to bring empty core 3 in operating position.
  • extension crank 25 urging against pawl 26 limits the movement of the arm 13, attached to air motor 19, but by the continuous energizing of the latter, spring 20, enclosed in dash pot 35 becomes compressed, whereas spring 21, also enclosed in dash pot 35 is stretched.
  • Arm 5 carrying guide shell 6 at its free extremity which encircles the empty core 3, carries also another air motor 9, which by means of a lever 12 pivotally secured to arm 5, urges roller 10 aganist core 3.
  • Roller 10 is slippingly driven and attains the same circumferential speed as that of core 3. When, however, roller 10 is free turning and out of contact with core 3, its circumferential speed exceeds that of core 3.
  • the cutting cycle itself is started when air motor 27 becomes energized and retracts pawl 26, freeing extension crank 25.
  • air motor 22 is energized causing the toothed end 23 at its associated lever to engage the teeth 24 latching thereby the arm 13 in that position and at the same time to preventing possible oscillation of the latter.
  • the web 1 continues to advance at its normal speed because it is pressed between roller 16 and core 3, the
  • the air motor 22 is energized in such a. way that its piston moves in an opposite direction, freeing the toothed end.
  • the same cycle is performed with air motor 9, causing roller 10 to come out of contact with the web.
  • the main air motors 7 and 19 return arms 5 and 13 to their starting positions, so that core 3 is no longer surrounded by guide shell 6 and the rollers 10 and 16.-
  • the partial rotation of arm 13 swings the extension crank 25 past the pawl 26, the air motor 27 becomes then energized so that the latter pushes said pawl in forward direction.
  • the roll 2, still being on the turret is removed theefrom by a kind of cradle mounted on one extremity of a turret 38 which forwards the roll to a receiving station (not shown).
  • a fork 42 forces a core 39 into stand-by position with the help of a cradle 41 actuated by a vertically operating air motor 37.
  • the utilization of the sudden freeing of accumulated energy combined with the use of mechanical parts of low weight enables a quick and clean cutting of the web.
