It is located above the core 8. At this time, the first and second transport devices 4 and 5 are stopped after a fixed amount is fed out from the transport device 5 so that the web 2 can be passed over the winding core 8. Further, if the conveyance amount by the first and second conveyance devices 4 and 5 after the intake / exhaust bar 19 adsorbs the web 2 is the same as or slightly smaller than the movement amount of the intake / exhaust bar 19, the web 2 may not be loosened. . Thereafter, as shown in FIG. 7 (c), the first and second conveying devices 4 and 5 stop, and the intake / exhaust bar 19 descends while adsorbing the web 2 to wind the web 2 into the winding core 8. To stop the adsorption. In this state, the web 2 is stretched in the conveying direction by the contact friction force caused by the rotation of the winding core 8 with glue.

  In this state, as shown in FIG. 7 (d), the intake / exhaust hole 18 is brought into the suction state, and the intake / exhaust bar 19 is moved upward from the outlet portion of the transport device 5 to the upstream side of the take-up core 8 so as to wind. Appropriate tension is applied to the web 2 wound around the core. This operation has an effect of aligning the respective rows obtained by dividing the web 2 in the width direction by the slitter 17 to obtain multiple rows. The winding core 8 is rotating and eliminates the slack of the web 2. The continuation of the above operation is the same as the operation shown in (f), (g), and (h) of FIG.

  Next, an example of the effect | action of the terminal process of the web 2 in the winding roll 13 after winding the web 2 conveyed by the 1st, 2nd conveying apparatuses 4 and 5 by rotation of the winding core 8 is shown. 8 (a), (b), (c), (d), (e), and (f) will be described.

  FIG. 8A shows a state in which the web 2 conveyed by the first and second conveying devices is being wound by the winding core 8 of the winding device 7, and the web braking at this time is shown. The intake / exhaust bar 19 of the device 14 is located at the outlet of the second transport device 5 and is lowered so that the tip thereof does not contact the web 2. When the take-up roll 13 taken up by the take-up core 8 has a predetermined diameter, the rotation of both the conveying devices 4 and 5 and the take-up core 8 is stopped and as shown in FIG. The cutter 6 is actuated to separate the web 2 between the first and second transport devices 4 and 5. At this time, the terminal portion on the winding roll 13 side of the web 2 after separation is held by the second conveying device 5 to maintain the back tension.

  In the state where the terminal portion on the take-up roll 13 side is sandwiched by the second conveying device 5, the intake / exhaust bar 19 of the web braking device 14 is lifted as shown in FIG. Is brought into contact with the lower surface of the web 2 and moved up to the vicinity of the take-up roll 13 stopped while pushing it up.

  At this time, as shown in FIG. 8 (d), when the intake / exhaust bar 19 vertically rises from the outlet of the second transport device 5 to push up the web 2, the second transport device 5 and the take-up roll 13 are moved. The path of the web 2 between them becomes two sides of the triangle and becomes slightly longer, and the part is pulled out by the slippage of the web 2 in the second conveying device 5. When the intake / exhaust bar 19 moves in parallel to the vicinity of the take-up roll 13 in this state, the path of the web 2 becomes one side of the triangle again, as shown by the chain line in FIG. The route becomes shorter. Therefore, when the intake / exhaust bar 19 is moved as shown in FIG. 8D as described above, the intake / exhaust bar 19 is moved to the vicinity of the take-up roll 13 and the second transport device 5 is wound up. The web 2 between the rolls 13 will sag due to the change in the path length.

  The sagging of the web 2 is absorbed by the tensile elasticity of the web 2 when the end of the web 2 is not separated by the cutter 6 and is connected to the upstream side of the first conveying device 4, and the above path Although no sagging due to the change in length occurs, when the web 2 is separated on the upstream side of the second conveying device 5 as shown in FIG. 8C, the sagging occurs directly. It will be.

  Therefore, as shown in FIG. 8 (c), the operation of the intake / exhaust bar 19 when the web 2 is separated on the upstream side of the second conveying device 5 is shown in FIG. 8 (e). The upper end is moved up so as to draw an arcuate locus A having a radius R substantially similar to the arc on the outer periphery of the winding roll 13. As a result, the amount of the web pulled out by the slippage of the web 2 in the second conveying device 5 increases with the upward movement, and the upper moving end, that is, the intake / exhaust bar 19 moves to the vicinity of the take-up roll 13. In addition, the amount of the web drawn out by the slippage of the web 2 in the second conveying device 5 can be minimized, and the sagging of the web 2 can be prevented. Further, in synchronization with the upward movement, the second conveying device 5 is driven (slightly less than the amount of the web pulled out by the upward movement), so that the web 2 is less rubbed by the conveying device 5. When the clamping force of the device 5 is weak, the web 2 can be expected to slip in the transport device 5, so the second transport device 5 at this time may be stopped. Further, the upper and lower conveying belts 5a and 5b constituting the conveying device 5 may be brought into contact with and separated from each other so that the holding force (back tension) of the web 2 can be adjusted.

  At this time, the intake / exhaust bar 19 moves while the upstream corner of the bar contacts and slides on the web 2, so in order to reduce the contact resistance in this part, for example, an RFID label or the like is loaded with an IC. In order to prevent the chip from being damaged, although not particularly shown, the upstream corner of the intake / exhaust bar 19 may be arcuate.

  As shown in FIG. 8C, the web 2 is adsorbed on the upper surface of the intake / exhaust bar 19 with the intake / exhaust bar 19 moved to the vicinity of the take-up roll 13. In this state, the second vacuum conveyor 25 of the sticking device 16 rotates downward and is pressed against the outer peripheral surface of the take-up roll 13.

  Next, as shown in FIG. 8 (f), the web 2 is wound up by rotating the winding roll 13 while sucking air from the intake / exhaust bar 19 of the web braking device 14. At this time, the web 2 is held between the upper and lower conveyors 5a and 5b up to the outlet of the second conveyor 5 to maintain the back tension. At this time, the second transport device 5 is driven in synchronization with the rotation of the take-up roll 13 (slightly slower than the take-up speed of the take-up roll 13), so that the web 2 is less rubbed by the transport device 5. The transfer device 5 may be stopped.

  When the cut end of the web 2 comes out of the second conveying device 5, this end becomes free, but this portion is adsorbed by the intake / exhaust bar 19 of the web braking device 14 in the vicinity of the take-up roll 13. Since it is held, the terminal portion of the web 2 with respect to the winding roll 13 is maintained in a state where the braking force is actuated by the web braking device 14 and is still constrained to the vicinity of the winding roll 13.

  The second vacuum conveyor 25 of the sticking device 16 is operated with the terminal portion of the web 2 coming to the peripheral surface of the take-up roll 13, and is transferred from the first vacuum conveyor 24 to the second vacuum conveyor 25. An end label seal is attached so as to straddle the end portion of the web 2 and the peripheral surface of the roll 13, and the end surface portion of the web 2 is fixed to the take-up roll 13. Then, the 2nd vacuum conveyor 25 of the sticking apparatus 16 rotates upwards, and winding-up of the web 2 to the winding-up roll 13 is complete | finished.

  The take-up roll 13 that has been wound up is taken out by the roll take-out device 12 shown in FIG. Further, the web braking device 14 stops the suction of the intake / exhaust bar 19 and returns to the position shown in FIG. 8A, that is, below the outlet of the second transport device 5. Further, in the winding device 7, the support shaft 9 b that engages the wound winding core 8 that is rotated by one pitch is positioned at the winding position, and the web 2 is wound by the action shown in each drawing of FIG. 6. Operation is performed.

  8 (b) and 8 (c), the web 2 is separated by the cutter 6 and then the intake / exhaust bar 19 of the web braking device 14 is moved upward so that the web 2 The example shown in FIGS. 8B and 8C is the same as that shown in FIGS. 9A, 9B, and 9C. As shown in FIG. 9A, the take-up roll 13 has a predetermined diameter, the suction / exhaust bar 19 is moved to the vicinity of the stopped take-up roll 13, and the web 2 is adsorbed and stuck on the upper surface thereof. The second vacuum conveyor 25 of the apparatus 16 may be pressed against the peripheral surface of the take-up roll 13 (FIG. 9B), and then the web 2 may be separated by the cutter 6 while the web 2 is stopped. . In this state, the web 2 is sandwiched between the second conveying devices 5 and the back tension is maintained with respect to the take-up roll 13 (FIG. 9C). Next, as shown in FIG. 8 (f), the terminal portion of the web 2 is wound around the winding roll 13.

  Such a method of moving the intake / exhaust bar 19 to the vicinity of the take-up roll 13 before the separation of the web 2 is a method regardless of the movement trajectory of the web 2 as described above. This is an effective method when the roll diameter at which is increased is small or the paper path is long.

  FIG. 10 and subsequent figures show other examples of the second transport device.

  FIG. 10 omits the upper conveying belt 5a of the second conveying device 5 shown in FIGS. 8 and 9, and uses two feeding rolls 5c and 5d.

  Further, FIG. 11 is a diagram in which the second transport device 26 is replaced with upper and lower feed rollers 26a and 26b instead of the second transport device 5 of FIGS. Same as shown in FIG.

  FIG. 12A shows an example in which the second conveying device 27 is only the upper guide roller 27a that rotates freely. In this case, as shown in FIG. 12 (b), when the take-up roll 13 has a predetermined diameter, the intake / exhaust bar 19 moves to the vicinity of the take-up roll 13 that has stopped rotating, and the sticking device 16 is in the position where it is worn. It becomes. The web 2 goes back to the first conveying device 4 on the upstream side of the cutter 6 and the elongation (tension) of the web 2 is absorbed. Then, as shown in FIG. 12C, the web 2 is separated by the cutter 6 while the web 2 is stopped. The separated web 2 is in a free state as shown in FIG. 12C, but the braking force is still applied to the web 2 by suction holding by the intake / exhaust bar 19 in the vicinity of the winding roll 13. Therefore, the back tension of the take-up roll 13 is maintained up to the vicinity of the take-up roll 13 by the braking force by the intake / exhaust bar 19. Then, while the winding roll 13 rotates, an end seal is stuck on the terminal of the web 2 of the winding roll 13 by the sticking device 16, and terminal processing is carried out. This embodiment is effective for winding a single row web without using the slitter 17.

  FIGS. 13 (a) and 13 (b) show the operation of transferring the web 2 in the embodiment shown in FIG. 12, and the web from the first conveying device 4 as shown in FIG. 13 (a). 2 is sent to the downstream side of the guide roller 27a, and the tip of the intake / exhaust bar 19 is raised to the running height of the web 2 in a state where the length of the guide roller 27a reaches a predetermined length. And move horizontally to the downstream side of the guide roller 27a (FIG. 13B). From this state, the tip of the web 2 is blown upward, or the intake / exhaust bar 19 is moved to the vicinity of the take-up core 8, and the portion of the web 2 protruding to the downstream side of the intake / exhaust bar 19 is taken up. I'm trying to hang it over. In the following, the same operation as that shown in FIG.

  The second transport device 28 shown in FIG. 14 has a configuration in which a receiving plate 29 is disposed below the guide roller 28 a that freely rotates above the second transport device 28. The operation in this embodiment is the same as that in the embodiment shown in FIG. This embodiment is also effective for winding a single row web without using a slitter.

  In addition, you may make the cross-sectional shape of the intake / exhaust bar 19 of the web braking device 14 in above-mentioned embodiment into the wedge shape which made the one close | similar to the winding roll 13 into an acute angle, as shown in FIG. In this case, since the surface of the intake / exhaust bar 19 provided with the nozzle can be closer to the vicinity of the roll 13, the back tension can be applied to the web 2 to the vicinity of the take-up roll 13.

  FIG. 16A shows another example of the web braking device, and the web braking device 30 in this embodiment uses clamping members 31 a and 31 b that clamp the web 2 from above and below instead of the intake and exhaust bars 19. It is configured.

  This web braking device 30 includes upper and lower clamping members 31a and 31b formed in a bar shape elongated in the width direction of the web 2 on the support arm 22 that supports the intake / exhaust bar 19 shown in FIG. It is configured to be movable in the vertical direction and in the direction opposite to each other, and the web 2 fed from the downstream side of the second transport device 5 is passed between the both clamping members 31a and 31b. Thus, a braking force is applied to the web 2. In addition, you may comprise these both clamping members 31a and 31b with the roller which has predetermined rotation resistance and rotates.

  The operation of this embodiment will be described below with reference to FIGS.

  When the web 2 sent out from the second transport device 5 has a predetermined length, the both holding members 31a and 31b are moved toward each other to hold the web 2 as shown in FIG. 16 (b). The clamping force at this time is adjusted by adjusting the actuation force in the clamping direction by the actuation device.

  Next, as shown in FIG. 16 (c), the web 2 is held by the both clamping members 31 a and 31 b of the web braking device 30, and the both clamping members 31 a and 31 b are moved along the winding core 8 along with the travel of the web 2 being conveyed. It moves to the upper upstream vicinity and positions the front-end | tip part of the web 2 above the winding core 8 which is rotating. At this time, the first and second transport devices 4 and 5 are stopped after a fixed amount is fed out from the transport device 5 so that the web 2 can be passed over the winding core 8. Further, if the transport amount by the first and second transport devices 4 and 5 after the web 2 is sandwiched between the sandwiching members 31a and 31b is equal to or slightly smaller than the travel amount of the sandwiching members 31a and 31b, the web 2 You don't have to relax.

  Thereafter, the web 2 is lowered while being clamped by the both clamping members 31a and 31b of the web braking device 30, and the web 2 is stretched over the winding core 8 as shown in FIG. 16 (d). The web 2 is released by moving 31a and 31b away from each other. Thereby, the front-end | tip part of the web 2 is contacted with the winding core 8 to which glue is adhered, and is stretched in the transport direction by the contact frictional force caused by the rotation of the winding core 8. Thereafter, as shown in FIG. 16 (e), both the clamping members 31a and 31b move to the vicinity of the exit of the conveying device 5, and then the web 2 is clamped by the both clamping members 31a and 31b, as shown in FIG. 15 (f). As shown, it moves to the upstream vicinity of the winding core 8 and tensions the web 2 with an appropriate tension. This operation has an effect of aligning the respective rows obtained by dividing the web 2 in the width direction by the slitter 17 to obtain multiple rows. Since the winding core 8 is rotating, the web 2 is not slackened.

  Thereafter, the rotation of the winding core 8 is stopped, and in this state, as shown in FIG. 16G, the second vacuum conveyor 25 of the sticking device 16 is moved downward to press and adhere the web 2 to the winding core 8. Fix it. With the web 2 fixed to the take-up core 8 as shown in FIG. 16 (h), the holding of the web 2 by the holding members 31a and 31b of the web braking device 30 is released, and the both holding The members 31a and 31b are moved to a standby position near the exit of the transport device 5. Thereafter, the winding core 8 is rotated, and the web 2 fed out by driving the first and second conveying devices 4 and 5 is wound around the winding core 8.

  At the time of web terminal processing of the take-up roll 13 when the web braking device 30 of this other example is used, the web 2 is clamped by the clamping members 31a and 31b of the web braking device 30 as shown in FIG. The web terminal processing using the web braking device 30 is performed in the same manner as the operation shown in FIG.

  In this embodiment, the lower clamping member 31b may be fixed in the vertical direction, and the upper clamping member 31a may be moved in the vertical direction. In this case, the lower holding member 31 b is moved in an arc shape having a radius R according to the winding diameter of the winding roll 13.

  In each of the above embodiments, the second conveying device disposed on the downstream side of the cutter 6 may be a belt conveyor that is driven for conveyance or a roller that rotates freely, and a member that conveys and guides the web on the downstream side of the cutter 6. If it is.

  The control device previously controls the operation of each device that performs the operation of passing the web 2 around the winding core 8 using the web braking device 14 and the terminal processing operation of the web 2 after winding using the sticking device 16. Can be automatically performed by the operation stored in (teaching).

  For example, in the crossing action of the web 2 shown in FIGS. 6A to 6H, the web 2 is conveyed quantitatively to the winding core 8 by the first and second conveying devices 4 and 5 that perform servo operation. Done. At this time, the web 2 is stretched around the winding core by ejecting air from the intake / exhaust holes 18 of the intake / exhaust bar 19 of the web braking device 14 located below the outlet of the second transport device 5. Next, the web braking device 14 is operated by numerical coordinate point command control by automatic calculation so that air is sucked from the intake and exhaust holes 18, and the upper surface of the intake and exhaust holes 18 is brought into contact with the lower surface of the web 2. It moves in parallel until just before the winding core 8 (FIGS. 6A to 6E).

  At this time, the web 2 is attracted smoothly to the intake / exhaust hole 18, and an appropriate frictional resistance is generated between the upper surface of the intake / exhaust bar 19 and the web 2, so that the web 2 takes up the hair with a comb. Align in a direction perpendicular to the core 8.

  Next, in a state where the web 2 is lightly in contact with the upper surface of the winding core 8, the second vacuum conveyor 25 of the sticking device 16 is rotated downward to press the web 2 against the winding core 8, which is in contact with the winding core 8. When detected by the sensor, the second vacuum conveyor 25 is driven, and the first and second conveying devices 4 and 5 and the winding core 8 are driven in synchronization with the second vacuum conveyor 25 to wind the web 2. Adhering firmly by winding a certain amount while pressing on the core 8. Thereafter, the second vacuum conveyor 25 is moved upward, and the web braking device 14 is returned to the lower outlet side of the conveying device 5 in a state where the suction of air through the intake / exhaust holes 18 is stopped (FIG. 6 (f) to ( h)). Each timing of this series of operations is automatically adjusted by automatic calculation numerical control. The operation can also be corrected by system parameters.

  Next, in the terminal processing action of the web 2 after winding shown in FIGS. 8A to 8F, the web braking device 14 in a state where the web 2 that has been transported is separated by the cutter 6. In the state where air is sucked from the intake / exhaust hole 18 of the intake / exhaust bar 19, the upper surface of the intake / exhaust bar 19 is moved to the vicinity of the winding roller 13 while sliding while contacting the lower surface of the web 2. In this state, the second vacuum conveyor 25 of the sticking device 16 is rotated downward and pressed against the outer peripheral surface of the take-up roll 13 (FIGS. 8A to 8C). This series of operations is performed by numerical coordinate point command control by automatic calculation. At this time, when the web 2 is separated by the cutter 6 before the operation by the web braking device 14, the operation of the intake / exhaust bar 19 of the web braking device 14 is circular as shown in FIG. Act in an arc. The state in which air is sucked from the intake / exhaust hole 18 may be after the intake / exhaust bar 19 has moved to the vicinity of the take-up roller 13.

  At this time, the separation of the web 2 by the cutter 6 is performed after the sticking device 16 is pressed against the take-up roll 13 by the second vacuum conveyor 25, and this pressing is detected by a contact sensor. May be.

  Next, when the pressing by the second vacuum conveyor 25 is detected by the contact confirmation sensor, the second conveying device 5 and the winding core 8 are operated to wind the terminal portion of the web 2 with the winding roll 13. To go. At this time, the web 2 is smoothly drawn to the intake / exhaust bar 19 by the suction action of the intake / exhaust hole 18 of the intake / exhaust bar 19 of the web braking device 14, and an appropriate amount of frictional resistance is generated between the upper surface of the intake / exhaust bar 19. As a result, the web 2 is shaped like a comb having its hair taken by a comb, and is in a state perpendicular to the winding core 8 (FIG. 8 (f)). Each timing is automatically adjusted by automatic calculation numerical control. It can also be corrected with system parameters.

  The terminal portion of the web 2 separated by the cutter 6 by the mechanism operation is unattended and automatically wound around the winding roll 13 unattended.

  For automatic calculation numerical control for performing such automatic adjustment, a conventionally known calculation control device is used.
