Definitions
- This invention relates to a system and method for cutting with a tape a travelling web of paper .being wound on a first spool and for transferring the oncoming web to an empty spool for continued winding by attaching to the far end of an empty spool a cutting tape emerging from a guideway conducting the cutting tape from a supply and processing area adjacent the near end of the empty spool.
- the guideway ex ⁇ tends transversely underneath the travelling web and has a lengthwise slot facing upwardly toward the web.
- the cutting tape has a forward cut end coated with an adhesive for a short distance along the center portion thereof and leaving the edges free of adhesive to be slidingly supported in the guide ⁇ way along such edges.
- the improvements comprise a sensor to detect the presence or absence of a length of adhesive on the cut end; a sensing means to detect the passage of the cut end beyond the means for applying adhesive; a means to divert the cutting tape into storage space or temporarily housing a long length of the tape; a means for selectively switching the guideway to direct the cutting tape to a waste collection area or toward the far end of the guideway; and a final pro ⁇ pelling means for advancing the cut end from adjacent the far end to contact with the empty spool; the means for cutting the tape is located between the supply source and the adhesive application means; and a brake means selectively clamps the tape to the guideway so that a loop of tape is formed.
- the system provides means for physically removing a portion of the guideway so as to permit loop formation while being en ⁇ gaged in the guideway at the forward end of the loop.
- the preferred adhesive applicator includes a release tape to which double-sided pressure sensitive adhesive tape is at ⁇ tached and a roller means for attaching a portion of the adhesive tape to the forward end of the cutting tape.
- Another specific embodiment includes an operational connection be ⁇ tween the sensor to detect the presence or absence of adhesive tape on the cutting tape, and a switch to divert to a waste collection area any tape that does not contain the adhesive tape attached thereto.
- the system also prefers the far end of the guideway to end closely adjacent to the empty spool and to include a propelling means adjacent the near end of the guideway for extending the forward end of the tape to the nip of the empty spool without the assistance of a mechanical arm.
- FIR. 1 is a schematic view in perspective of the system of this invention
- FIG. 2 is an enlarged schematic view in elevation of the control mechanism of the system of the invention
- FIG. 3 is a cross sectional view taken at 3—3 of FIG. 1 or FIG. 2;
- FIG. 4 is a cross sectional view taken at 4—4 of FIG. 2.
- FIG. 1 shows the general type of equipment employed in a paper manufacturing plant to wind up the manufactured paper on rolls for storage and use elsewhere.
- a c _.ontinuous .web of paper 20 travels at a rela- tively rapid rate of speed to a combination of spools upon which the paper is rolled.
- Paper web 20 advances toward ten ⁇ sion roll 21 mounted in journals on supports 22, leading web 20 over driving roll 23 and winding about spool 24 turning in the direction of arrow 25.
- Driving roll 23 turns in the di ⁇ rection of arrow 26 and is pressed against the paper roll on spool 24 causing it to rotate in the indicated direction.
- spool 24 When spool 24 has been filled to the desired capacity with paper from web 20, it is necessary to cut web 20 laterally, transfer the cut edge to an empty spool 27, and start the web winding on that spool in the direction of arr-w 28 to eventually pro ⁇ cute another filled spool, such as spool 24.
- Empty spool 27 is positioned vertically above the location shown in FIG. 1 until it is ready to accept paper from web 20 and begin winding it up.
- Spool 27, which may or may not be separately rotated as known in the art, is lowered until it contacts driving roll 23 and rotates with it, as shown in FIG. 1.
- Paper web 20 is then cut and the leading edge of web 20 is wrapped around an empty spool so that it may continue to wind up web 20 until that spool is ready to be replaced with still another empty spool.
- the web 20 is cut by introducing a cutting tape 33 at its forward end 34 into the nip 29 of empty roll 27 and driving roll 23 at the far end of the rolls causing tape 33 to wrap itself helically around spool 27 while cutting web 20 transversely in front of spool 27 and automatically carrying web 20 onto spool 27 to continue the winding of web 20 thereon.
- the cutting tape 33 is conducted from near end 32 to far end 31 in a guideway 30 passing underneath travelling web 20.
- forward end 34 of tape 33 is conducted to ad ⁇ jacent the exit from guideway 30 at far end 31 and stops there to await the appropriate time to be moved forward to enter nip 29.
- the final movement of forward end 34 into nip 29 may be automatic depending on the movement of some part of the system as, for example, the primary arms of the spools actuating a limit switch, or it may be accomplished by the operator actuating a switch.
- Cutting tape 33 as described in my previous patents is a plurality of parallel strands of twisted repulpable paper fibers and is stored on a large supply spool 35, from which it is led into the entrance 40 of guideway 30 and conducted in an upside-down T-slot as shown in FIG. 3 where the cross bar 73 of the T is the conduit for cutting tape 33 and the leg 74 of the T is an opening extending lengthwise of guideway 30.
- a shallow recess 75 along the bottom of cross bar 73 is incor ⁇ porated in the guideway so that the corresponding portion of cutting tape 33 above that rece-s may be coated with adhesive and not be in contact with guideway 30. It may be seen that cutting tape 30 is supported in its movement by the side edges of the tape in the side edges of cross bar portion 73. Tape 33 is sufficiently stiff to bridge this recess 75 and provide no frictional drag problems as tape 33 moves through guideway 30.
- Tape 33 from supply roll 35 passes between rolls 36 and 37 and is propelled by driving roll 36 having tape 33 pressed there against by pressure roll 37. Pressure is ap ⁇ plied by means of lever 38 to which is attached a pneumatic cylinder device 39 causing roll 37 to press against roll 36.
- Roll 36 is rotated by means not shown here, such as a shaft driven by a pulley and a belt from a motor.
- Tape 33 enters guideway 30 at entrance 40 into the T-slot described above and its presence is sensed by a photocell sensor 40'. If no tape thereat, the operator changes the supply roll and/or starts it between rolls 36 and 37. Tape 33 is propelled all the way across to far side 31 to the end of guideway 30 such that cut end 34 is about 3 inches short of nip 29.
- Sensor 77 notes that cut end 34 has passed by, and signals bra influence ke cyl ⁇ inder 60 and loop gate cylinder 57 to function.
- sensor 77 may be omitted and pressure roll 37 controlled so as to rotate a selected number of revolutions and portions of revolutions, as measured by equidistant pick-up points 79 on roll 37, passing sensor 80, so as to propel cut end 34 to exactly the position desired ⁇ hort of nip 29.
- Brake pads 59 which oppose each other from both sides of tape 33 are squeezed together by pneumatic cylinder means 60 to stop any further movement of tape 33 toward far side 31.
- Pneumatic cylinder 57 actuated to cause section 56 of the T-slot in guideway 30 to be withdrawn leaving an unobstructed opening 58 into the temporary storage space below.
- This storage space is defined by guide walls 69 and permits a large loop 70 of tape 33 to hang down as seen in FIG. 2.
- Driving roll 36 continues to propel tape 33 into entrance 40 causing loop 70 to form.
- Pressure roll 37 is calibrated to turn a given number of revolutions so as to propel a selected length of tape 33 and t ⁇ n to stop automatically.
- guillotine cutter 41 is actuated by pneumatic cylinder
- cylinder 64 is activated moving lever 63 to cause press roll 62 to press tape 33 against propelling roll 61 to rotate a selected amount.
- a preferred procedure is to employ a rack 81 and pinion 83 combination in which a selected linear movement of a rack 81 through support bearing 82 causes pinion gear 83 to turn and rotate roller 61 in the direction of arrow 78 to push cut end 34 forward until it is caught in nip 29.
- brake pads 59 are pressed together to provide resistance to the movement of tape 33 in guideway 30.
- Tape 33 is helically wrapped around empty spool 27 and pulled taut because of the resistance provided by brake 59. This causes tape 33 to cut paper web 20 and to guide the cut edge onto spool 27 for winding up.
- the operator When the paper web 20 is safely and securely attached to spool 27 and being wound thereon, the operator causes a new cycle of operations to start that will result in having another length of tape 30 ready to be advanced into nip 29 to cut web 20 and start a new spool 27.
- the operations on the leading cut end 34 begin as it passes adhesive applicator roll 46 where single length, e.g., 3-4 inches, of double- sided pressure-sensitive adhesive tape on a supply tape 48 from supply roll 47 passes under tape 33 and is pressed against tape 33 by press roll 43, pushed downwardly by lever 44 operated by pneumatic cylinder means 45.
- the length of double sided adhesive tape 48 is adhered to tape 33 and while release liner 49 is peeled away from the adhesive tape and wound onto windup roll 50.
- roller 51 which causes a signal to be sent from sensor housing 52 to pneumatic cylinder 45 to cause press roll 43 to lift slightly from tape 33 so as not to apply any further pressure to tape 33 at applicator roll 46 and thereby to attach only one length of adhesive tape, to cutting tape 30.
- Tape cut end 34 then passes over sensor roller 53 which has a metal surface or other surface which tends to cling to the adhesive of the pressure sensitive tape on the bottom side of tape 33 applied at roll 46.
- the passage of the length of - double-sided adhesive tape causes sensor roll 53 to rotate and thereby to swing arm 54 in a circle that passes near mag ⁇ netic switch 55.
- 60, 64 and 66 could be hydraulic cylinders, solenoids, or other linear movement devices.
- Adhesive application system of rolls 43, 46, 47 and 50 could be replaced by adhesive spray systems, or adhesive roll-on systems as described in my U.S.
- Sensing devices 51, 52, 53, 54 and 55 could be repla _.ced by light beam or X-ray beam interrupting systems or other similar detectors known in the art.
- the operation of levers 38, 43, and 63 could be spring biased so as to assume one position automatically and to be moved by the corresponding pneumatic cylinders in only one direction rather than two.
- track switch 65 could be spring biased to be in one position automatically, and be moved to the other position only when signalled to do so.
