  • SHEET 1 [IF 3 luvs TORS. L TosH/sAau/zo 0 .4, Kuu/o Yea/#20164,
  • This invention relates to a method of an apparatus for taking up on a reel such tape as unsintered polytetrafluoroethylene tape which is flaccid and apt to become elongated or folded.
  • tape such as unsintered polytetrafluoroethylene tape for example
  • a fixed length (for example, m or m) is then measured out from these long-length pads and taken up on a reel.
  • the position of the tape moves left and right while travelling (hereinafter such movement will be termed as snaking), so that there may take place such drawbacks that the tape hits the flanges of the reel to become bent and taken up in a irregular condition on the reel (hereinafter referred to as reel collapse) or the tape becomes folded and is taken up in the folded condition.
  • the general practice is to cause the travelling tape to pass between guides provided at points left and right of adjacent to the reel to prevent tape displacement.
  • the guides would cause the tape to become folded and taken up on the reel in that folded condition.
  • This invention represents an improvement in a method and apparatus for reeling the tape always in a stabilized condition without reel collapse or tape folds caused by tape snaking when a long length of such tape, as mentioned above, which is flaccid and is liable to become elongated or folded, is taken up on a reel to a requisite or desired length.
  • FIG. 1 is a plan view of the tape reeling apparatus comprising this invention.
  • FIG. 2 is a side elevation of the apparatus shown in FIG. 1.
  • FIG. 3 (i) to 3 (v) is a sequential diagrammatic illustration of the functioning mechanism of the apparatus before and after the starting of tape reeling with the tape gripper provided in the center.
  • an installation base plate 1 of the vertical type which is provided with a rotary axle 2 so as to enable a pad 3 of reeled, long length unsintered polytetrafluoroethylene tape or the like may be mounted thereon.
  • a plurality of rotary axles 2 for mounting long-length pads 3 may be provided as indicated in FIGS. 1 and 2.
  • a tension control mechanism A for the purpose of adjusting the tension to a fixed amount when paying out the tape 4 from the pad 3.
  • a lever b is attached to the installation base plate 1 which can pivot about the axis a.
  • a lever (h) is attached to the installation base plate 1 having a pivotal axis (f).
  • the lever (b) and the lever (h) are movably connected or linked together by means of a vertical lever (e).
  • a spring (j) is provided with one end connected to the installation base plate 1 at (i) and its other end connected to the lever (.12).
  • a belt (k is fixed approximately to the middle of the lever (h). This belt (k) goes around its rotary axle 2 and has the other end connected to an adjustable stopper l provided on the installation base plate 1. By the adjustment of its screw, the adjustable stopper (1) can regulate the effective length of the belt (k).
  • the belt (k) brings its face in contact with the rotary axle and thereby suitably restricts the rotation of the rotary axle 2 and the longlength pad 3 supported by the axle.
  • the tension roller system (A) is responsive to slight changes in the tension when the tape 4 is moved in the direction of the arrow 5. For instance, when the tension on the tape has increased, the end tape guide (4:) of the lever (b) moves downward and as a result the connecting point (g) of the outer end of the lever (h) and the vertical lever (d) will be moved downward so that the belt (k) in contact with the circumference of the rotary axle 2 is slackened and the braking effect on the rotary axle is thereby lessened. In this way the increase in tape tension will be mitigated.

  • the cutting blades 40 provided symmetrically both left and right positions. While the tape is taken up on the reel 41, the grippers 42 are open and do not interfere with the passage of the tape 4. When a prescribed length has been taken up on the reel 41, the reel 41 comes to a stop. After that, as shown in FIG. 3 (ii), the grippers 42 grip the tape 4 and at the same time the tape tension roller 44 comes out against press the taken-up tape 4 on the reel 41 to the reel.
  • the cutting blades 40 are provided to move inwardly and cut the tape at which time the reel 41 rotates one turn so that the end of the cut tape 4 adheres to the tape already taken up on the reel 41.
  • the cutting blades 40 and tape pusher roller 44 are retracted and the next empty reel comes into the position of the reel 41, the grippers 42 are moved forward, gripping and pulling the tape therealong, until the end of the cut tape 4 has reached the central axle of the new empty reel 41.

  • the end of the tape 4 is, therefore, easily attached to the central axle of the empty reel, and the take-up operation can be started at once.
  • Each long-length pad 3 of unsintered polytetraflueroethylene tape is set on the revolving axle 2.
  • the end of tape 4 passes through the tension, as shown, and the face of the tape 4 is turned degrees between the guide pin 10 and the guide pin 12, so that the direction of the width of the tape after its passage by the guide pin 12 is about perpendicular to the horizontal installation has plate 11.
  • the tape passes between the guide roller 14a 14 and the roller of the L-shaped lever 16.
  • the angular position the guide pins relative to the horizontal installation base plate 11 on the side where the tape 4 contacts the guide pins can be selectively adjusted so that the tape is constantly subjected to a downward controlling force when it moves in and out of contact with these guide pins. If the guide pins are given such an angular position, the tape will not move beyond the top of the pins by virtue of the weight of the tape itself and the inclination of the pins. Since the tape is thus always under the influence of the downward controlling force and moves in such a condition that it barely touches the base plate 1 1, the snaking of the tape can be avoided.
  • the tape 4 which has passed by the guide pin 22 passes through the grippers 38 and cutting blades 40 and reaches the reeling position.
  • the coupling element 34 moves downwardly and engages an empty reel in the concavity 25, while the tape extension roller 44 presses the end of the tape 4 against the central axle of the empty reel for adhesion due to the deposit of paste on the reel core or hub. Thereafter reeling of a predetermined length of tape commences.
  • An electric motor controlling method is employed to control the speed of reeling wherein the speed increases gradually at the start of reeling and decreases gradually at the end of reeling.

  • the cylindrical cam 19 is revolved by the travel of the tape 4 and measures the length and opening and closing the microswitches 21, 20.
  • the microswitch 21 controls the voltage by the thyristor and if it is closed the speed of the tape which is being taken up on the empty reel gradually decreases and eventually comes to a stop. Due to the action of the microswitch 21, an independent timer is actuated and after the reel has come to a stop, the tape is gripped by the grippers 38 and the tape 4 is extend cut by the cutting blades 40, which blades are then returned to their original position.
