  Further, in the apparatus disclosed in the publication, when the web material is wound, the facing roller faces the winding roll. Further, the take-up roll is supported by the support, and the support is supported by the carriage. As the winding diameter of the take-up roll increases, the carriage moves in the horizontal direction and the support moves backward from the opposing roller. This allows an increase in winding diameter.

  Furthermore, after the winding of the web material is completed, the carriage or the conveyor moves in the horizontal direction and is disposed below the winding roll. Thereafter, the carriage or the conveyor moves up toward the take-up roll, and the take-up roll is transferred to and supported by the carriage or the conveyor. Further, after the take-up roll is delivered, the carriage moves in the horizontal direction, the support member moves away from the take-up roll, retreats to the outside thereof, and the take-up roll is sent and taken out by a carriage or a conveyor.

  However, in the case of the apparatus of the publication, it is necessary to move the carriage or the conveyor in the horizontal direction and raise it toward the take-up roll, and the horizontal movement drive mechanism and the lift drive mechanism must be specially provided. Is complicated and expensive. Further, after the take-up roll is delivered, the carriage must be moved in the horizontal direction so that the support is separated from the take-up roll and retracted to the outside. In order to take out the take-up roll after delivery of the take-up roll, the cart or the conveyor must be lowered and moved to return to the original position, and there is a problem that the required time is long.

  Accordingly, an object of the present invention is to simplify the configuration and reduce the cost in a winding device of a winding roll horizontal movement type.

  Another purpose is to eliminate the problem of required space.

  Another object is to shorten the time required for taking out the take-up roll.

A web material 1 such as paper or a plastic film is slit into a plurality of strips, and the web material 1 is wound around a winding roll 2 after the slitting. It is the same as that of the gazette.

  Further, in this apparatus, the web material 1 is slit by the slit blade 3, and then the web material 1 passes through the guide roller 4 and the counter roller 5 and is guided to the winding roll 2, and the web material 1 is transferred to the winding roll 2. It is wound up. Furthermore, when the web material 1 is wound up, the facing roller 5 faces the winding roll 2. In this embodiment, the opposing roller 5 is a touch roller. And the opposing roller 5 is supported by the lever 6, the cylinder 7 acts on the lever 6, the winding roll 2 contacts the opposing roller 5, and a contact pressure arises between both.

  Furthermore, as shown in FIG. 2, this apparatus has a plurality of winding arms 8, which are arranged at intervals and extend upward from a horizontal support shaft 9. And the winding roll 2 is supported by the upper part. The support shaft 9 extends parallel to the take-up roll 2.

  In this embodiment, the take-up arm 8 is attached to and supported by the linear guide 10 on the support shaft 9, and each take-up arm 8 is moved along the linear guide 10, and the interval is arbitrarily adjusted. Can do. Further, a chuck 11 is provided on the upper part of the winding arm 8, and a plurality of winding cores are arranged between the winding arms 8 and are chucked on the chuck 11. Further, the winding roll 2 and the drive motor 12 are connected by a chain or belt 30 and a sprocket or pulley 31. Then, the chuck 11 and the winding core are rotated by the drive motor 12, the chain or belt 30, and the sprocket or pulley 31, and the web material 1 is wound around each winding core. It is formed. Therefore, the winding roll 2 is supported on the upper part of the winding arm 8.

  Further, the winding arm 8 and the turning drive mechanism are supported by the carriage 13. The turning drive mechanism is for turning the winding arm 8, and the winding arm 8 turns around the support shaft 9. In this embodiment, a carriage 13 and a bearing box 14 are provided at both ends of the support shaft 9, respectively. The support shaft 9 is supported by the bearing box 14 and guided rotatably, and the bearing box 14 is attached to the carriage 13. Further, as shown in FIG. 3, a cylinder 16 is used for the turning drive mechanism, and its piston rod 15 is connected to a lever 18. Further, the lever 18 is fixed to the support shaft 9, the plate 19 is fixed to the carriage 13, and the cylinder 16 is supported by the plate 19. Therefore, the winding arm 8, the support shaft 9 and the cylinder 16 are supported on the carriage 13. Then, the piston rod 15 is moved by the cylinder 16, the lever 18 and the support shaft 9 are rotated by the piston rod 15, and the winding arm 8 is rotated integrally with the support shaft 9.

  Further, this is combined with a horizontal movement drive mechanism. The horizontal movement drive mechanism is for moving the carriage 13, and the carriage 13 moves in the horizontal direction perpendicular to the support shaft 9. In this embodiment, as shown in FIGS. 2 and 4, the carriage 13 is supported by the linear guide 20 and the rail 37, and is guided so as to be movable along the rail 37. The rail 37 is provided on the base 24. Further, as shown in FIGS. 3 and 4, a feed screw 21, a nut, and a drive motor 22 are used for the horizontal movement drive mechanism. The feed screw 21 extends in a horizontal direction perpendicular to the support shaft 9 and is supported by a bearing 36. The nut is built in the carriage 13 and screwed to the feed screw 21. Further, as shown in FIG. 4, the connecting shaft 23 extends in parallel to the support shaft 9, and the drive motor 22 is connected to one end thereof. The connecting shaft 23 is supported by a bearing 34. Further, the feed screw 21 and the connecting shaft 23 are connected by the gear box 32. A coupling 33 is provided between the drive motor 22, the connecting shaft 23 and the gear box 32. A coupling 35 is provided between the feed screw 21 and the gear box 32. That is, the feed screws 21 are connected by the connecting shaft 23. Therefore, the connecting shaft 23 and the feed screw 21 can be rotated by the drive motor 22, and the carriage 13 can be moved by the feed screw 21 and the nut.

  Further, the web material 1 is taken up on the take-up roll 2, thereby increasing the roll diameter. In this apparatus, the roll diameter of the take-up roll 2 is detected by a sensor. The sensor is one that is commonly used. Further, a control device is connected to the cylinder 16, the drive motor 22 and the sensor. Its operation will be described later. Furthermore, this device has a carriage 25 on which the take-up roll 2 is placed. The carriage 25 is disposed outside the winding arm 8 and the support shaft 9 and is movable along the rail 26. The rail 26 extends in the arrangement direction of the winding arms 8.

  In this apparatus, when the web material 1 is taken up, the drive motor 22 is controlled by the control device based on the detection signal of the sensor, and the carriage 13 moves relative to the support shaft 9 as the winding diameter of the take-up roll 2 increases. Then, the winding arm 8 moves backward from the opposing roller 5. This allows an increase in winding diameter.

  Then, after the winding of the web material 1 is completed, the web material 1 is cross-cut between the winding roll 2 and the opposing roller 5. In this way, the start end and the end are formed. Thereafter, the beginning and end are processed.

  Thereafter, the cylinder 16 is controlled by the control device, and the winding arm 8 turns in a direction away from the facing roller 5 and tilts around the support shaft 9. Therefore, the winding roll 2 can be lowered toward the carriage 25 and transferred to the carriage 25.

Further, as described above, when the web material 1 is wound up, the carriage 13 moves in the horizontal direction perpendicular to the support shaft 9 and the winding arm 8 moves backward away from the opposing roller 5. In this embodiment, after the winding of the web material 1 is completed, not only the cylinder 16 but also the drive motor 22 is controlled by the control device. Then, as shown by the phantom line in FIG. 1, at the same time as the pivoting of the take-up arm 8, carriage 13 is moved in the horizontal Direction winding arm 8 is advanced so as to approach the opposite roller 5.

  Further, as described above, the winding diameter of the winding roll 2 is detected by the sensor. In this embodiment, after the winding of the web material 1 is completed, the driving motor is driven by the control device based on the detection signal of the sensor. 22 is controlled and the amount of movement is adjusted, whereby the winding roll 2 and the carriage 25 are centered. Therefore, even if the winding roll 2 has a different winding diameter, the winding roll 2 can be lowered toward the carriage 25 and delivered to the carriage 25 regardless of the winding diameter.

  Furthermore, when the winding roll 2 comes into contact with the carriage 25, the cylinder 16 and the winding arm 8 stop at that position. Thereafter, in each winding arm 8, the winding core is unchucked from the chuck 11, and the winding roll 2 is transferred to the carriage 25 and supported by the carriage 25. Thereafter, the cylinder 16 is controlled by the control device, and the winding arm 8 turns in the reverse direction and stands up. Therefore, after that, the carriage 25 can travel along the rail 26 and the take-up roll 2 can be taken out by the carriage 25.

  Thereafter, a new winding core is disposed between the winding arms 8 and chucked on the chuck 11. Further, the carriage 13 moves in the horizontal direction, the winding arm 8 advances toward the opposing roller 5, and the opposing roller 5 comes into contact with the winding core. Further, the chuck 11 and the winding core are rotated by the drive motor 12, and the web material 1 is wound around the winding core.

  Therefore, in the case of this apparatus, the winding roll 2 can be transferred to the carriage 25 only by turning the winding arm 8 by the cylinder 16 and tilting the winding arm 8. There is no need to move the carriage 25 in the horizontal direction, there is no need to raise it toward the take-up roll 2, the configuration is simple, and the cost is low.

Further, simultaneously with the pivoting of the take-up arm 8, carriage 13 is moved in the horizontal Direction winding arm 8 is advanced so as to approach the opposite roller 5. Accordingly, on the outside of the winding arm 8 and the support shaft 9, the carriage 25 can be brought close to the winding arm 8 and the support shaft 9, the distance between them is small, and the required space is small.

  Further, after the take-up roll 2 is transferred to the carriage 25 and the take-up arm 8 is swung in the reverse direction to stand up, it can be taken out as it is, and the required time is short.

  Note that, instead of the cylinder 16, a feed screw such as an electric actuator, a nut, and a drive motor are used for the turning drive mechanism, and the feed screw is rotated by the drive motor, and the winding arm 8 is turned by the feed screw and the nut. Good. Further, instead of the feed screw 21, the nut and the drive motor 22, a cylinder may be used for the horizontal movement mechanism, and the carriage 13 may be moved by the cylinder.

  Instead of the carriage 25, a conveyor may be used, the winding roll 2 may be transferred to the conveyor, and the winding roll 2 may be taken out by the conveyor.

  An arithmetic device is used instead of the sensor, and the arithmetic device determines the rotation number of the winding roll 2 and the thickness of the web material 1 or the rotation number of the winding roll 2 and the rotation speed of the guide roller 4 of the web material 1. After the winding diameter of the winding roll is calculated and the winding of the web material 1 is completed, the drive motor 22 is controlled by the control device based on the calculation signal of the calculation device, and the amount of movement is adjusted, whereby the winding roll 2 is adjusted. The cart 25 may be centered.

  Alternatively, after the winding of the web material 1 is completed, when the winding arm 8 turns and the center of the winding roll 2 is positioned above the carriage 25 or the conveyor, the center of the winding roll 2 is detected by the sensor, and the sensor Based on this detection signal, the drive motor 22 may be controlled by the control device to adjust the amount of movement thereof, whereby the winding roll 2 and the carriage 25 may be centered. For example, as shown in FIG. 2, the dog 27 is arranged around the support shaft 9 at the same angular position as the winding arm 8 and is fixed to one end of the support shaft 9. The length from the center of the support shaft 9 to the tip of the dog 27 is the same as the length from the center of the support shaft 9 to the chuck 11 of the winding arm 8. Furthermore, as shown in FIG. 5, a pair of photoelectric sensors 28 are used as sensors. The photoelectric sensor 28 is disposed at a position corresponding to the dog 27 in a vertical plane 29 parallel to the support shaft 9 and passing through the carriage 25 or the conveyor. Therefore, after the winding of the web material 1 is completed, when the winding arm 8 turns and the center of the winding roll 2 is positioned above the carriage 25 or the conveyor, the center of the winding roll 2 is detected by the dog 27 and the photoelectric sensor 28. , And based on the detection signal of the photoelectric sensor 28, the drive motor 22 is controlled by the control device and the movement amount is adjusted, whereby the winding roll 2 and the carriage 25 or the conveyor can be centered.

The winding roll 2 may be disposed with a gap from the opposing roller 5 without bringing the winding roll 2 into contact with the opposing roller 5. Even in this case, when the web material 1 is wound up, the winding roll 2 moves backward away from the opposing roller 5 so that the gap is kept constant, thereby allowing an increase in the winding diameter. Needless to say.

  Further, the winding arm 8 may be fixed to the support shaft 9 so that the winding arm 8 cannot move in the axial direction.

  Further, the mounting method of the winding core to the winding arm 8 may be a shaftless method or a shaft type.
