Definitions

  • the invention relates to a method and apparatus for preparing for splicing a new paper roll for rotary press or the like.
  • paper web consuming or processing machines all such machines to which the invention finds applications will be generally referred to as "paper web consuming or processing machines".
  • old paper roll will be used herein and in the claims appended hereto to mean the roll, that has been consumed or processed.
  • new paper roll signify the fresh roll, that is to be, or being, spliced to the old roll.
  • U.S. Patent No. 4,233,104 describes and claims apparatus constructed to carry the zero speed method into practice.
  • the apparatus broadly comprises an infeed mechanism for feeding a web in to a consuming or processing machine, a splicer mechanism incorporated with the infeed mechanism for splicing successive rolls of the web, and a web storage machanism interposed between the infeed mechanism and the consuming or processing machine for holding a required length of the web for delivery to the consuming or processing machine during the splicing or successive web rolls.
  • the infeed mechanism has a pair of roll holder arms medially pivoted for joint rotation.
  • the roll holder arms carry old and new web rolls on their opposite ends, and the splicer mechanism therebetween.
  • the splicer mechanism includes a pair of nip rolls movable toward and away from each other and having suction ports created therein. Upon decrease of its radius to a prescribed degree the old web becomes locked against rotation to discontinue the payoff of the web therefrom and hence to allow this web to be spliced to the new web.
  • the web storage mechanism operates to feed the web length that has been stored therein into the consuming or processing machine.
  • the new web roll has attached to its leading end a piece of tape having adhesive layers on its opposite faces. This taped end of the new web is held by suction against one of the nip rolls of the splicer mechanism.
  • the old web is wrapped around the other nip roll on its way toward the web storage mechanism.
  • the old and new webs can therefore be joined together via the adhesive tape by pressing the nip rolls against each other.
  • the old web is cut off from its roll by a knife positioned adjacent the nip rolls. Then the infeed mecahnism resumes the feeding of the web from the new roll.
  • the speed matching method also dictates the use of an infeed mechanism comprising a pair of rotatable roll holder arms, but of no webs storage mechanism.
  • the roll holder arms rotatably carry old a new web rolls on their opposite ends.
  • the roll holder arms extend approximately vertically, with the old web roll held above the new web roll below.
  • the roll holder arms are turned approximately 180 degrees, so that the new web roll comes above and the old one comes below.
  • a speed matching mechanism including a drive roll which is movable into and out of peripheral contact with the new web roll.
  • the drive roll revolves the new web roll about its own axis at a peripheral speed equal to the running speed of the old web traveling therepast.
  • a retractable splicer mechanism which, when in its working position, guides the old web thereover so as to pass sustantially tangentially of the new web roll.
  • the splicer mechanism presses, with a brush incorporated therein, the old web againnst an adhesive region at the leading end of the new web. Then the old web is severed from its roll by a knife disposed adjacent the splicer brush.
  • the infeed mechanism commences the payoff of the web from the new roll whereas the splicer mechanism returns to its retracted position.
  • the zero speed and speed matching schemes have their own drawbacks.
  • the old and new webs are joined together by the pair of nip rolls spaced from their rolls. This requires the manual threading of the leading end of each new web, with an adhesive tape attached thereto, between the nip rolls, thus making difficult the full automation of the apparatus.
  • the adhesive tape moreover, must be attached to the new web roll on the splicer mechanism; it cannot be applied to new web rolls preparatory to their mounting on the apparatus.
  • the apparatus embodying the speed matching scheme requires the expensive speed matching mechanism for precisely synchronizing the peripheral speed of the new web roll with the running speed of the old web.
  • the speed matching method is also more difficult to practice than the zero speed method.
  • the successive web rolls are likely to be spliced improperty, or not spliced at all, if the leading end of the new web roll comes off during the rotation of the roll or if its peripheral speed does not equal to the running speed of the old web by reason of, for example, the eccentricity of the new web roll. Further the old web has a considerable length of its portion trailing behind the region where it is adhered to the new web.
  • this trailing end portion should be reduced to a minimum so as not to interfere with the operation of the web consuming or processing machine. It is also a disadvantage of the speed matching method that the adhesive region or regions on the leading end of each new web must be of-very complex pattern in order to afford a firm bond to the old web, since the webs are spliced while running. The preparation of such complex adhesive regions is of course a troublesome and time consuming job which is difficult of automation.
  • the prior art web feeders built on both the zero speed and the speed matching schemes have an additional problem in common with regard to the alignment of the successive web rolls.
  • the aforesaid pair of roll holder arms have two pairs of opposed chucking cones on their opposite ends for engagement in the respective hollow cores of the old and new web rolls.
  • a still further problem with the prior art concerns the means for preventing the end of each web roll from coming off the roll.
  • Taping is the usual expedient to this end.
  • the web end must readily come off the roll when spliced to the old web.
  • the conventional practice has been to apply relatively wide, strong tape to each web roll to prevent the loosening of its end during transportation and handling.
  • the strong tape is peeled off the web roll just before its use, and narrower, easier-to-break tape is applied in several spaced apart positions across the web end.
  • the narrower tape as heretofore used has been too weak to hold the web end against the roll and has been easy to break during the handling of the roll as for mounting the same on the pair of roll holder arms.
  • the present invention overcomes the weaknesses of, and derives strengths from, the known zero speed scheme and speed matching scheme in providing an improved method and apparatus for preparing for, positively and accurately splicing a new paper roll and continuously feeding the web into a desired web consuming or processing machine.
  • the method and apparatus in accordance with the invention are based upon an improved version of the zero speed scheme as both old and new webs are held stationary during splicing.
  • the invention solves the problem of how to automatically align the sucessive web rolls in splicing them, in order to assure proper consumption or processing by the web consuming or processing machine.
  • the invention makes it possible to firmly hold the end of each web roll in position on the roll during its transportation and handling but, nevertheless, to allow the web end to readily come off the roll on being spliced to the old length of web.
  • the improved method of this invention comprises the steps of: preparing a strong adhesive tape having on one surface thereof a central nontacky zone and adhesive tacky zones flanking opposites of the nontacky zone; sticking beforehand, upon completion of reeling of paper to form the roll, a plurality of pieces of the adhesive tape over and to the web end and the part of the roll adjacent thereto so that the nontacky hone of each tape piece is disposed over and along the web leading edge of the roll; and, after the roll has been loaded onto a paper feed apparatus including web splicing means, forming from the outside a perforated line for tearing across each tape piece in the nontacky zone thereof substantially in the vicinity of and along the web leading edge thereby to facilitate tearing of the tape pieces and peeling of the web leading edge part immediately prior to web splicing.
  • the improved method of this invention combines the advantages of the conventional zero speed scheme and speed matching scheme and eliminates their disadvantages, making it possible to firmly splice successive paper rolls and uninterruptedly feed the paper into a desired paper web consuming or processing machine through a full automatic sequence.
  • the apparatus comprises a paper roll being rotatably supported and having a web leading edge held against raveling by a plurality of pieces of adhesive tape; a traveling structure mounted for travelling parallelly to and in the vicinity of the web leading edge from one end to the other end of the paper roll; a rotary perforating wheel supported by the traveling structure with freedom to be pressed against and be separated from the surface of the paper roll driving means for thus moving the rotary perforating wheel against and away from the paper roll surface; tape detecting means so supported on the traveling structrue as to detect the adhesive tape pieces as the travelling structure thus travels and to output corresponding detection signals; and control means operating in response to the detection signals to activate the driving means to move the rotary perforating wheel against and along only the adhesive tape pieces an thereby to form a tearable perforated line across only the adhesive tape pieces substantially over and along the web leading edge, whereby tearing of the tape pieces and peeling of the web leading edge part immediately prior to web s
  • FIGS. 1 through 7 illustrate a preferred form of the apparatus in accordance with the invention, which features a perforating mechanism seen at 120 in FIGS. 1 and 2.
  • the perforating mechanism 120 is used for perforating one or more pieces of adhesive tape attached to each new web roll to retain the leading end of the web in position thereon, as pictured at Ta in FIG. 3.
  • the adhesive tape Ta will hereinafter be referred to as the web end retainer tape.
  • FIG. 3 three pieces of web end retainer tape Ta are shown attached to the unused web roll R2 across the leading edge E of the web.
  • each piece of web and retainer tape Ta has a central nonadhesive region 121 positioned across the leading web edge E, and a pair of adhesive regions 122 on opposite sides of the nonadhesive region which are attached to the web. Additional tape having adhesive layers on its opposite surfaces is attached to the leading end of the web, as indicated by the phantom outline designated T in FIG. 4, in overlying relation to parts of the web end retainer tape Ta in order to provide the adhesive region for use in splicing the new web roll to the old web roll.
  • the web end retainer tape Ta Being wider and sturdier than the tape heretofore used to this end, the web end retainer tape Ta is not to easily break during the transportation of the web rolls or at the time of their mounting on the roll holder arms. However, the web retainer tape should readily break when each new web roll is spliced to the old by the method and apparatus of this invention. This becomes possible by creating a line of perforations or small incisions, as seen at 123 in FIG. 4, in each piece of web end retainere tape Ta by the perforating mechanism 120 after mounting the web roll in position on the apparatus.
  • the perforations 123 are formed in the nonadhesive region 121 of the web end retainer tape Ta so as to extend along the edge E of the rolled web. Thus perforated, the web end retainer tape will tear easily after the splicing of the web roll via the adhesive region T thereon.
  • FIGS. 5 through 7 While the perforating mechanism 120 appears in FIGS. 1 and 2, its details will be better understood from a study of FIGS. 5 through 7. It includes a pair of guide rods 143 extending horizontally in parallel spaced relation to each other, in a direction parallel to the rotary shaft 4, FIG. 1, carrying the pair of roll holder arms 8a and 8b, and having their opposite ends bracketed at 137 to the pair of side frames 3 of the apparatus.
  • a carriage 144 Slidably mounted on the guide rods 143 is a carriage 144 carrying a rotary perforator 162 together with means for automatically moving the same between working and retracted positions on the carriage.
  • wire rope 146 having its opposite ends both anchored to a lug 145 on the carriage and extending along a pair of pulleys 148 on the respective brackets 137. While the left hand pulley 148, as seen in FIGS. 5 and 7, is mounted directly on the corresponding one of the brackets 137, the right hand pulley 148 is mounted on the output shaft of a motor drive unit 150 which is supported upstandingly on the other bracket 137 via a mount 151. The bidirectional rotation of the motor drive unit 150 results in the back and forth travel of the carriage 144 along the guide rods 143.
  • the carriage 144 has an L-shaped carrier arm 153 depending therefrom.
  • a fluid actuated cylinder 155 of the double acting type is pivotally supported at is head end by a pivot 154 and so is disposed in a generallay upright attitude.
  • the cylinder 155 has a piston rod 156 extending downwardly therefrom and terminating in a coupling member 157, which is pin jointed at 158 to one of the angled arms of a bell crank 159.
  • This bell crank is pivoted at the apex of its two arms on the extreme end of the L-shaped carrier arm 153 by a pin 160.
  • the aforesaid rotary perforator 162 is rotatably mounted on the distal end of the other arm 159a of the bell crank 159 via a shaft 161.
  • the rotary perforator 162 is in the form of a wheel having a series of teeth 162a on its periphery.
  • the teeth 162a are to be incised into the web end retainer tap Ta on each new web roll R2 supported by the roll holder arms as in FIG. 1, thereby creating a line of perforations therein.
  • the L-shaped carrier arm 153 has also mounted thereon a phototube BS for optically sensing the three pieces of web end retainer tape Ta on the new web roll R2.
  • the phototube BS is electrically connected to a cylinder control 165 of largely conventional make which controls the delivery of pressurized fluid to the opposed fluid chambers of the cylinder 155 in response to the output from the phototube.
  • the cylinder control 165 has a built-in timer, not shown, for a purpose yet to be described.
  • the contraction and extension of the cylinder 155 results, of course, in the movement of the rotary perforator 162 into and out of perforating engagement with the web end retainer tape Ta on the new web roll R2.
  • FIG. 1 It will be understood from a consideration of FIG. 1 that, although not specifically illustrated, the other details of construction of the FIGS. 1 through 7 apparatus are substantially analogous with those of the two preceding forms of the apparatus.
  • the new web roll R2 with the web end retainer type Ta attached in place thereto is mounted on the pair of roll holder arms 8a and 8b while these are in a first preassigned angular position.
  • the roll holder arms are turned to a second preassigned angular position.
  • FIG. 1 shows the roll holder arms in this second preassigned angular position, with the new web roll R2 held opposite to the web traveling from the old web roll R1 past the splicer mechanism 25.
  • the motor drive unit 150 is set into rotation in a predetermined direction to cause the rightward travel of the carriage 144 along the guide rods 143. Traveling rightwardly with the carriage 144, the phototube BS delivers to the cylinder control 165 a signal indicative of the presence or absence of the three pieces of web end retainer tape Ta thereunder. Since the rotary perforator 162 lags behind the phototube BS during the rightward travel of the carriage 144, the unshown timer built into the cylinder control 165 causes contraction of the cylinder 155 upon lapse of a preset length of time following the detection of each piece of web end retainer tape by the phototube BS.
  • the bell crank 159 Upon contraction of the cylinder 155 the bell crank 159 is pivoted in a counterclockwise direction, as seen in FIG. 5, thereby causing the rotary perforator 162 to cut into the detected piece of web end retainer tape and hence to create the line of perforations 123, FIG. 4, in its non-adhesive region 121 by rolling thereover.
  • the cylinder control 165 causes the cylinder 155 to extend for moving the rotary perforator out of engagement with the web roll.
  • the perforating mechanism 120 repeats the foregoing operation upon detection of each of the successive pieces of web end retainer tape Ta by the phototube BS.
  • the motor drive unit 150 is reversed in rotation to move the carriage 144 back to the initial position, where a limit switch, not shown, is activated to set the motor drive unit out of rotation.
  • the new web roll R2 is revolved about its own axis, as by a clutch motor, through a predetermined angle 83, FIG. 1, in a clockwise direction as seen in this latter figure.
  • This clockwise rotation of the new web roll through the predetermined angle is intended to bring the adhesive region T thereon to a position of register with the splicer brush 27 of the splicer mechanism 25. Therefore, the new web roll can then be spliced to the web traveling therepast from the old web roll R1.
  • the leading end of the new web will readily come off the roll on being spliced to the old web as then the pieces of web end retainer tape Ta will tear along the lines of perforations 123.
