It controls operations related to winding of the conveyed product 2 onto the winding shaft 80, rewinding, and the like.

For example, the control unit 70 acquires the conveying speed of the conveyed article 2, and when the wind arm unit 20 supporting the winding shaft 80 in the fully wound state moves from the winding position to the standby position, the wind arm unit 20 The moving speed of each of the supported winding shaft 80 and the cutting unit 50 is controlled to a moving speed corresponding to the conveying speed of the article to be conveyed.

Next, the operation flow from winding of the conveyed product 2 by the winding device 1 to rewinding of the winding shaft 80 will be described with reference to FIGS. 1 to 12. FIG. 1 to 10 are side views of the winding equipment 100 showing the state of the winding device 1 in each process from winding to rewinding of the conveyed article 2. FIG. The arrows inside the out-feed rolls 111 and 112, the winding shaft 80, the near roll 51, etc. in FIGS. 1 to 10 indicate their rotational directions. In FIG. 1, the winding shaft 80 on which the conveyed article 2 is wound is referred to as a winding shaft 81, and the winding shaft 80 positioned at the standby position and on which the conveyed article 2 is wound next (hereinafter referred to as a new winding shaft 80). ) will be described as the winding shaft 82 .

As shown in FIG. 1 , in the initial stage of the process of winding the article 2 , the article 2 sent out by the outfeed mechanism 110 is wound on the winding shaft 81 positioned on the outfeed mechanism 110 side. In the example shown in FIG. 1, the first wind arm portion 21 and the second wind arm portion 22 extend from the base portion 10 in opposite directions in the X direction. That is, the angle of the second wind arm portion 22 with respect to the first wind arm portion 21 positioned at the winding position is 180°. The position of the second wind arm portion 22 in this state is defined as the first waiting position among the waiting positions. The first standby position is a position where work for removing the winding shaft 80 from the winding device 1 is performed. Also, the near arm portion 40 extends in the X direction so as to overlap the first wind arm portion 21 in a side view. By controlling the operation of the near arm portion 40 by the control portion 70, the cutting portion 50 moves in the direction of the arrow F1 as the diameter of the winding shaft 81 increases so that the distance between the winding shaft 81 and the near roll 51 is maintained at a preset distance. move to As a result, it is possible to prevent the article 2 from collapsing on the winding shaft 80 when the article 2 is wound on the winding shaft 80 .

When the outer diameter of the winding shaft 81 reaches a predetermined size, the rewinding mechanism 30 rotates the second wind arm portion 22 in the direction of the arrow F2 as shown in FIG. position toward the second standby position near the winding position.

3 shows the winding device 1 in a state where the second wind arm portion 22 has completed the movement to the second standby position, and FIG. 4 shows the winding device in a state where the outer diameter of the winding shaft 81 is larger than that in FIG. 1 is shown. As shown in FIGS. 3 and 4, the second wind arm portion 22 remains at the second standby position until the winding shaft 81 supported by the first wind arm portion 21 is fully wound. At this time, as shown in FIG. 3, the take-up shaft 82 rotates to a position where the end face of the double-faced tape attached to the outer circumference of the take-up shaft 82 overlaps the end face of the conveyed article 2 to be cut during rewinding.

Here, an example of a method for setting the second standby position will be described. FIG. 11 is a schematic diagram showing the positional relationship between the turning area B of the wind arm portion 20 and the winding shaft 80 in the fully wound state. The second standby position is set using the following equations (1) and (2), for example.

d is the outer diameter of the winding shaft 80 in the fully wound state. L is the length of the wind arm portion 20 . According to the equations (1) and (2), the second wind arm portion 22 with respect to the first wind arm portion 21 when the new winding shaft 80 contacts the outer circumference of the winding shaft 80 in the fully wound state. Angle θ is calculated. Then, an angle θ' is calculated by adding a preset value to the calculated angle θ. For example, when the first wind arm portion 21 is positioned at the winding position, the position of the second wind arm portion 22 at which the angle of the second wind arm portion 22 with respect to the first wind arm portion 21 is θ′ is the second standby position. position.

When the winding shaft 81 reaches a fully wound state with a preset diameter, as shown in FIG. Rotate. That is, the first wind arm portion 21 moves from the winding position toward the standby position. Specifically, the rotation of the winding shaft 81 is stopped in a predetermined deceleration time, and the first wind arm portion 21 is moved by the rewinding mechanism 30 for the same time as the deceleration time of the winding shaft 81, and the outfeed mechanism 110 carries out the transport by the outfeed mechanism 110 . It is accelerated to the same speed as the transport speed of the object 2 . At this time, the cutting portion drive mechanism 60 operates the near arm portion 40 so that the angle of the near arm portion 40 with respect to the base portion 10 is the same as the angle of the second wind arm portion 22 with respect to the base portion 10 . That is, the cutting portion drive mechanism 60 rotates the near arm portion 40 so as to overlap the second wind arm portion 22 in a side view. Further, the cutting section drive mechanism 60 moves the cutting section 50 in the axial direction of the near arm section 40 in a direction closer to the winding shaft 82 .

As shown in FIG. 6, the second wind arm portion 22 and the near arm portion 40 rotate about the rotation axis A in the direction of arrow F4. That is, the second wind arm portion 22 and the near arm portion 40 move so as to follow the movement of the first wind arm portion 21 from the winding position to the first standby position. At this time, the control unit 70 acquires the conveying speed of the conveyed article 2 and controls the operations of the rewinding mechanism 30 and the cutting unit driving mechanism 60, so that the winding shaft 82, the winding shaft 81, and the near roll 51 The moving speed is matched with the conveying speed of the conveyed object 2. When the difference between the transport speed of the article 2 and the moving speed of the near roll 51 is substantially zero, the near roll 51 moves toward the rotation axis A until it contacts the winding shaft 82 as indicated by the arrow F1 in FIG. Moving.

As shown in FIG. 7 , when the near roll 51 is in contact with the winding shaft 82 , the tip of the near arm portion 40 further moves toward the rotation axis A, thereby cutting the cutting portion 50 supported by the near arm portion 40 . The blade 52 rotates in the direction of arrow F5 to cut the article 2 .

As shown in FIG. 8, when the article 2 is cut, the take-up shaft 82 starts to rotate in the reverse direction, and the double-faced tape attached to the take-up shaft 82 and the article 2 are pasted together on the near roll 51 . At this time, the second wind arm portion 22 is positioned at the winding position, and the first wind arm portion 21 is positioned at the standby position. On the other hand, the first wind arm portion 21 moves to the first standby position and stops.

After the article 2 is attached to the winding shaft 82, the second wind arm section 22 starts rotating in the direction of arrow F4 in FIG. Specifically, the rotation of the winding shaft 82 is accelerated to the conveying speed of the article 2 during the set acceleration time, and the movement of the second wind arm portion 22 is decelerated and stopped during the same time. At this time, the near roll 51 moves while maintaining the positional relationship calculated using the following formulas (3) to (13).

FIG. 12 is a side view showing the positional relationship between the winding shaft 80 on which the conveyed article 2 is wound and the near roll 51. As shown in FIG. 80A indicates the position of the winding shaft 80 supported by the horizontally extending wind arm portion 20, and 51A indicates the position of the near roll 51 at this time. 80B indicates the position of the winding shaft 80 when the angle of the wind arm portion 20 with respect to the base portion 10 is θ1, and 51B indicates the position of the near roll 51 at this time. L1 indicates the length of the wind arm portion 20, L2 indicates the distance from the center of the winding shaft 80 located at 80A to the center of the guide roll 143, and L3 indicates the distance from the center of the winding shaft 80 to the center of the near roll 51. distance.

The angle θ5 of the near arm portion 40 with respect to the base portion 10 when the winding shaft 80 is present at 80B according to the following equations (12) and (13) using the values calculated by the above equations (3) to (11), A distance L9 from the rotation axis A to the center of the near roll 51 located at 51B is calculated.

As shown in FIG. 10, rewinding is completed when the second wind arm portion 22 reaches a position extending in the horizontal direction. As shown in FIGS. 9 and 10, the operation of the near arm portion 40 is controlled by the control portion 70 according to the movement of the second wind arm portion 22 so that the position of the near roll 51 is always positioned near the winding shaft 82. be done.

Here, the conventional winding equipment 100' will be described with reference to FIG. FIG. 17 is a side view showing a conventional winding equipment 100'.

The winding equipment 100' comprises an outfeed mechanism 110, tension adjusting mechanisms 120, 130, 153', an accumulator device 160', a cutting section 50', and a winding device 1'. In the winding equipment 100 according to the above embodiment and the conventional winding equipment 100', the structure of the winding device 1' and the cutting part 50' are not included in the winding device 1', and the accumulator device 160' is not included in the winding device 1'. The main difference is the provision. In addition, the same reference numerals may be attached to the same configuration as the winding equipment 100, and the description thereof may be omitted.

The winding device 1′ includes a base portion (not shown), a first wind arm portion 21′ that rotatably supports a winding shaft 81, and a second wind arm portion 22 that rotatably supports a winding shaft 82. ', a guide roll arm portion 23' that supports the guide roll 25', a guide roll arm portion 24' that supports the guide roll 26', and a rewinding mechanism 30'.

As shown in FIG. 17, the first wind arm portion 21' and the second wind arm portion 22' extend from the rotation axis A in opposite directions. That is, the winding shaft 81 and the winding shaft 82 are arranged at positions facing each other with the rotation axis A interposed therebetween. The first wind arm portion 21' and the second wind arm portion 22' of the conventional winding equipment 100' are made of the same member and do not move individually. That is, the relative positional relationship between the first wind arm portion 21' and the second wind arm portion 22' is configured not to change.

The cutting portion 50' mainly includes a near roll 51', a blade 52', and a body portion 53'. The cutting section 50' is arranged at a predetermined interval on the upstream side of the conveying path C from the winding device 1'. In the example shown in FIG. 17 , the cutting portion 50 ′ moves to the upstream side of the conveying path C so as to keep a predetermined distance from the winding shaft 81 as the diameter of the winding shaft 81 increases. When the winding shaft 81 is fully wound, the blade 52' rotates with the first wind arm portion 21' positioned at the winding position, and the conveyed article 2 is cut. In the winding equipment 100' of FIG. 17, since the cutting part 50' is not included in the winding device 1', when the first wind arm part 21' rotates toward the standby position, It is not easy to move the cutting part 50' so as to follow the movement of the winding shaft 80 that rotates.

The accumulator device 160 ′ is a device that temporarily retains the continuously conveyed article 2 when the winding of the conveyed article 2 is stopped during rewinding of the winding shaft 80 . The accumulator device 160' includes guide rolls 161', 162' and 163', a dancer roll 164' disposed between the guide rolls 161' and 162', and guide rolls 162' and 163'. with a dancer roll 165' disposed between. As shown in FIG. 17, the downward displacement of the dancer rolls 164' and 165' causes the article 2 that continues to be conveyed even while the winding of the article 2 on the downstream side is stopped to the accumulator device 160'. stay inside.

In the winding equipment 100', the relative positional relationship between the two wind arm portions 20' supporting the winding shaft 80 does not change, and the cutting portion 50' can follow the movement of the wind arm portions 20'. difficult. For this reason, it takes time to move the winding shaft 82 to be used next from the waiting position to the winding position after stopping the winding of the conveyed article 2 or after cutting the conveyed article 2 . must be retained in the accumulator device 160'. Further, in order to rotate the wind arm portion 20' after cutting the conveyed object 2, it is necessary to separate the near roll 51' from the winding device 1'. 80 must be wound with the conveyed object 2 . For this reason, it leads to product loss such as occurrence of winding collapse.

On the other hand, the winding device 1 according to the present embodiment has a plurality of wind arm portions 20 that are individually movable, and is provided with a cutting portion 50 that can move from the winding position to the standby position. The cutting part 50 can be moved so as to follow the movement of the wind arm part 20 . As a result, even if the conveying of the conveyed article 2 toward the winding device 1 is not stopped and the winding on the winding shaft 80 is stopped during rewinding, the winding can be performed as shown in FIGS. It is possible to move the winding shaft 81 whose winding has stopped from the winding position to the standby position, and to cause the cutting part 50 to follow the movement of the winding shaft 81 . As a result, the winding shaft 81 moves to the downstream side of the conveying path C, so that the conveyed distance of the conveyed article 2 can be extended.
