    A Single-reel winding device and a method for replacing a full reel in
    A SINGLE-REEL WINDING DEVICE
    FIELD OF THE INVENTION [0001] The present invention relates to a single-reel winding device, and to a 5 method for replacing a full first reel in a single-reel winding device comprising a distributor wheel for distributing an optical fiber to the first reel.
    BACKGROUND OF THE INVENTION [0002] Previously, manual labour is involved in attaching an optical fibre to a full reel, cutting said optical fibre from the full reel, and attaching the optical fibre 10 to an empty reel in order to start winding of said optical fiber.
    [0003] One of the disadvantages associated with the above arrangement is that manually changing the reel is time consuming.
    BRIEF DESCRIPTION OF THE INVENTION [0004] It is thus an object of the present invention to provide a single-reel 15 winding device and a method for replacing a full reel in a single-reel winding device so as to overcome at least some of the above problems. The objects of the invention are achieved by a device and a method which are characterized by what is stated in the independent claims 1 and 10. The preferred embodiments of the invention are disclosed in the dependent claims.

    DETAILED DESCRIPTION OF THE INVENTION [0014] Figure 1 is an overall drawing of a single-reel winding device comprising a distributor wheel 1 for distributing an optical fiber 2 to a first reel 3 for winding the optical fiber 2 and a winder 4. In addition the single-reel winding device 10 comprises an attachment device 5 for attaching the optical fiber 2 to the first reel 3 when the first reel 3 is in the exchange area 6, a cutter 7 for cutting the optical fiber 2 when the first reel 3 is full and a gripper 8 for gripping onto the optical fiber 2, provided by the distributor wheel 1, and keeping the optical fiber 2 stationary during attaching and cutting of the optical fiber 2. The gripper 8 also keeps the optical 15 fiber stationary while the first, full reel 3 is removed from the exchange area 6 and a second, empty reel 9 is provided to the exchange area 6 in order to continue winding of the optical fiber 2.
    [0015] Figure 2 is a drawing showing an example of a winder 4. The winder 4 comprises a first rotatable pin 10 and a second rotatable pin 11, which pins 10,11 20 are arranged to attach to the first reel 3 for winding the optical fiber 2 on said reel.
    The winder 4 is arranged movably on guide tracks 12, for revolving the first reel 3 around a center axis 3-1 of the first reel 3 and for moving the first reel 3 along the center axis 3-1 between different positions in order to wind the optical fiber 2 onto the first reel 3, and for moving the first reel 3 to an exchange area 6 when the first 25 reel 3 is full.
    [0016] Figure 3a and 3b are drawings showing an example of the attachment device 5 and the gripper 8, respectively. Figure 3a is a drawing showing an example of an attachment device 5. Said attachment device 5 comprises a spring-biased frame 14 and a collector 15 for collecting a piece of tape. The spring biased frame 30 14 may be implemented with a telescopic design having two coaxially arranged parts generally tubular parts that are pushed away from each other by a spring in the frame, for instance. The attachment device 5 may be configured to collect a piece of tape from a tape supply station, for instance, in order to attach the optical fiber 2 to a reel with said piece of tape. The attachment device 5 may also comprise 35 a cutter 7. According to one embodiment, the cutter 7 is a blade, arranged alongside
    20185426 prh 08 -05- 2018 the spring-biased frame 14 of the attachment device 5.
    [0017] Figure 3b illustrates that the gripper 8 comprises movable jaws 13 arranged to open and to close for gripping on to the optical fibre 2. In addition, the gripper 8 may comprise an actuator for moving the gripper 8 towards the reel and 5 away from the reel.
    [0018] Figure 4 shows a block-diagram of a method for replacing a full first reel in a single-reel winding device comprising a distributor wheel 1 for distributing an optical fiber 2 to the first reel 3. Said method comprises (A) moving the first reel 3 away from the distributor wheel 1 when the first reel 3 is full until the optical 10 fiber 2 runs over a flange of the first reel 3, (B) gripping the optical fiber 2 at a position between the distributor wheel 1 and the flange of the first reel 3, (C) attaching the optical fiber 2 to the flange of the first reel 3, (D) cutting the optical fiber 2 at a position between the gripper 8 and the flange, (E) removing the first reel 3, (F) moving a second empty reel to a position where the optical fiber 2 runs over a 15 flange of the second reel 9, (G) attaching the optical fiber 2 to the flange of the second reel 9, (H) releasing the optical fiber from the gripper 8, and (I) initiating reeling of the optical fiber 2 to the second reel 9.
    [0019] Figures 5-8 further illustrate the method described in Figure 4. Figures 5a and 5b are front-view drawings illustrating the attachment and cutting of the 20 optical fiber 2. In Figure 5a, the winder 4 is arranged to move the first reel 3 away from the distributor wheel 1 when the first reel 3 is full, such that the gripper 8 can grip the optical fiber 2 at a position between the distributor wheel 1 and a flange of the first reel 3 which is closest to the distributor wheel 1. In other words, when the first reel 3 is full and has been moved to the exchange area 6, the gripper 8, which 25 is situated between a flange of the first reel 3 and the distributor wheel 1, moves towards the optical fiber for gripping onto the optical fiber by closing the movable jaws for keeping the optical fiber stationary. Holding the optical fiber stationary with the gripper 8 is advantageous as the optical fiber cannot escape during a reel exchange and it may be precisely positioned for attaching.
    [0020] After the gripper 8 has gripped onto the optical fiber 2, the attachment device 5 collects a piece of tape from the tape supply station 16 with the collector
    15. In order to attach the optical fiber 2 to the reel and cut the optical fiber 2 with a single motion, the collector 15 of the attachment device 5 is then pressed against the optical fiber 2 and a larger first flange 17 of the first reel 3. In other words, the 35 attachment device 5 presses the collector 15, having the piece of tape, against the optical fiber 2 and the larger first flange 17 of the full first reel 3 with such a force
    20185426 prh 08 -05- 2018 that the telescopic (for instance) spring-biased frame 14 of the attachment device 5 compresses sufficiently to move the cutter 7 past the collector 15 thus cutting the optical fiber 2. The attachment device 5 and may comprise an actuator 5-1 for moving the attachment device 5 and for pressing the collector 15 against the optical 5 fiber 2 and the reel. The gripper 8 may also comprise an actuator 8-1 for moving the gripper 8 towards and away from the optical fiber 2. Said actuators 5-1, 8-1 may be, for instance, pneumatic cylinders arranged movably on a rail 25, as illustrated in Figures 5a and 5b.
    [0021] When the optical fiber 2 has been attached to the full first reel 3 and cut, 10 the gripper 8, still holding the free-end of the optical fiber 2, moves away from the full first reel 3, so as to allow the full first reel 3 to be moved away from the exchange area 6 for moving the full first reel 3 on to the next processing sequence.
    One possible way to move the full first reel 3 the next processing sequence is illustrated in Figures 6a and 6b.
    [0022] Figures 6a and 6b are side-view drawings illustrating the extraction of a full first reel 3 from the single-reel winding device. In Figure 6a, a first extension arm 18, having an extracting end 19, extends from a downstream side of the production line 20 towards the full first reel 3 in such a way that the extracting end 19 is arranged under the full first reel 3. The winder 4 (not shown in Figures 6a and
    6b) then detaches itself from the full first reel 3 by moving the two rotatable pins
    10,11 away from each other thus releasing the full first reel 3 onto the extracting end 19 of the first extension arm 18 which then retracts back to the downstream side of the production line 20 with the first full reel 3. When the first extension arm 18 has been retracted back to the production line, the extracting end 19 tilts to25 wards the downstream side of the production line 20 due to contact with a roller or wheel arranged below the extension arm 18 in order to move the full first reel 3 to the production line, as is illustrated in Fig 6b.
    [0023] Figure 7a and 7b are side-view drawings illustrating the insertion of an empty second reel 9 to the single-reel winding device. The winder 4 (not shown in 30 Figures 7a and 7b) is arranged to, after removal of the full first reel 3, move the second empty reel 9 to a position where a flange of the second empty reel 9, which flange is located closest to the distributor wheel 1, is located between the distributor wheel 1 and the gripper 8, such that the attachment device 5 can attach the optical fiber 2 to the flange. In other words, after extracting the full first reel 3, the 35 winder 4 is moved back to the exchange area 6 and an empty second reel 9 is rotated to a suitable position for winding in an upstream side of the processing line
    20185426 prh 08 -05- 2018
    21, as shown in Figure 7a. The empty second reel 9 is rotated, for instance, by using rollers 22 arranged in a second extension arm 23 in order to obtain a position where holes in at least one of the flanges of the second reel 9 are rotated to a correct position to engage the corresponding pin 10 or 11 of the winder. The second ex- tension arm 23, having the empty second reel 9 at the extending end, then extends from the upstream side of the production line 21 towards the exchange area 6, as shown in Figure 7b.
    [0024] Figures 8a and 8b are front-view drawings illustrating the attachment of the optical fiber 2 to the empty second reel 9. Once the empty second reel 9 is in 10 the exchange area 6, the two pins 10,11 of the winder 4 move towards each other in order to attach onto the empty second reel 9, as shown in Figure 8a. The gripper 8, still holding the free-end of the optical fiber 2, is then lowered towards a smaller second flange 24 of the empty second reel 9 in order to position the free-end of the optical fiber against the smaller second flange 24 of the second reel 9, as shown in 15 Figure 8b. The attachment device 5 then collects a piece of tape from the tape supply station 16 with the collector 15, moves back to the empty second reel 9, and presses the collector 15, with said piece of tape, against the optical fiber and the second smaller flange 24 of the empty second reel 9 in order to attach said optical fiber to said flange. The collector 15 is pressed against the optical fiber 2 and the 20 second smaller flange 24 preferably with such a force that the spring-biased frame is not compressed to an extent where the cutter 7 moves past the collector 15 and cuts the optical fiber 2. The optical fiber 2 is then first wound onto the second smaller flange 24 for a predetermined amount of rounds before the reel is moved sideways in order to move the optical fiber 2 to a surface between the two larger 25 first flanges 17 of the reel to continue winding the optical fiber 2 on said surface.
    The first larger flange 17 of the reel may comprise an opening for allowing the optical fiber 2 to run past said flange.
    [0025] In Figures 5a, 5b and 8a, 8b, the attachment device 5, comprising the cutter 7, comprises only one actuator 5-1 for controlling the movement of both the 30 attachment device and the cutter. Another possibility is to provide one actuator for the attachment device 5 and another actuator for the cutter 7 in order to control the movement of said attachment device and said cutter separately.
    [0026] It will be obvious to a person skilled in the art that, as the technology advances, the inventive concept can be implemented in various ways. The inven35 tion and its embodiments are not limited to the examples described above but may vary within the scope of the claims.
