The movable bases 3a, 3b, 3c --- move along the guide rail 5, and the winding arm 1 also moves integrally therewith. As a result, the position and interval of the winding arm 1 can be adjusted in two steps to correspond to the slit width of the web material.
[0015]
For example, when the movable table 3a of FIGS. 1 and 4 is moved in a direction approaching the next movable table 3b, first, at one end portion 9 of the connecting rod 7 between them, the plate 8 is in the central portion 11 of the connecting rod 7. Engage with. Therefore, the connecting rod 7 is pushed and moved by the movable table 3a and the plate 8, and the central portion 11 is engaged with the plate 8 of the movable table 3b at the other end portion 10 of the connecting rod 7. As a result, the relative movement amount of the movable bases 3a and 3b is limited, and then the next movable base 3b is pushed and moved by the connecting rod 7. Therefore, the next movable base 3b moves in a direction approaching the third movable base 3c, and the plate 8 engages with the central portion 11 of the connecting rod 7 at one end portion 9 of the connecting rod 7 therebetween. Accordingly, the connecting rod 7 is pushed and moved by the plate 8, and the central portion 11 is engaged with the plate 8 of the movable table 3 c at the other end portion 10 of the connecting rod 7. Accordingly, the relative movement amount of the movable bases 3b and 3c is limited, and the third movable base 3c is pushed and moved by the connecting rod 7. This is repeated alternately one after another, and with the movement of the first movable table 3a, the other movable tables 3b and 3c can be moved by the connecting rod 7. The last movable base is fixed by the fixing means as described above. As a result, the movable bases 3a, 3b, 3c --- move to the positions shown in FIGS. Stop at that position.
[0016]
On the other hand, when the movable table 3a of FIGS. 3 and 5 is moved away from the next movable table 3b, the plate 8 is engaged with the nut 12 of the connecting rod 7 at one end portion 9 of the connecting rod 7 therebetween. To do. Therefore, the connecting rod 7 is pulled and moved by the plate 8 and the nut 12, and the nut 12 is engaged with the plate 8 of the movable table 3 b at the other end 10 of the connecting rod 7. As a result, the relative movement of the movable bases 3a and 3b is limited, and then the next movable base 3b is pulled and moved by the connecting rod 7 and the nut 8. Therefore, the next movable base 3b moves away from the third movable base 3c, and the plate 8 engages with the nut 12 of the connecting rod 7 at one end portion 9 of the connecting rod 7 therebetween. Therefore, the connecting rod 7 is pulled and moved by the plate 8 and the nut 12, and the nut 12 is engaged with the plate 8 of the movable table 3 c at the other end 10 of the connecting rod 7. As a result, the relative movement amount of the movable bases 3b and 3c is limited, and the third movable base 3c is pulled and moved by the connecting rod 7 and the nut 12. This is repeated alternately one after another, and the other movable bases 3b and 3c can be moved by the connecting rod 7 and the nut 8 as the first movable base 3a moves. As described above, the last movable base is fixed by the fixing means. As a result, the movable bases 3a, 3b, 3c --- move to the positions shown in FIGS. 1 and 4 and return. Stop at that position.
[0017]
Therefore, when changing the slit width of the web material, each of the movable bases 3a, 3b, 3c --- can be moved to the positions shown in FIGS. 1 and 4, and can also be moved to the positions shown in FIGS. it can. As a result, each take-up arm 1 is moved and its position and interval are changed and adjusted. Therefore, the position and interval of the winding arm 1 can be adjusted in two stages to correspond to the slit width of the web material. Regarding the position and interval of the winding arm 1, both end portions 9 and 10 of the connecting rod 7 are related thereto, and the position and interval of the winding arm 1 are changed by the length of both end portions 9 and 10 and adjusted.
[0018]
In addition, in the case of this apparatus, it is only necessary to connect the air cylinder 13 to the first movable table 3a and move the first movable table 3a by the air cylinder 13. About other movable stand 3b, 3c ----, it can be moved with the connecting rod 7. FIG. Its configuration is simple and the cost is low.
[0019]
The air cylinder is connected to not only the first movable table 3a in the arrangement direction X of the movable tables but also the last movable table. When the first movable base 3a and the last movable base are moved in the opposite directions, the other movable bases 3b and 3c are moved by the connecting rod 7 and the position and interval of the winding arm 1 are accordingly moved. Can be adjusted in two stages to correspond to the slit width of the web material.
[0020]
A plurality of pins are arranged in the arrangement direction X of the movable bases, and the pin holes are formed in the respective movable bases 3a, 3b, 3c ---, and the movable bases 3a, 3b, 3c --- are shown in FIG. When moving to the position, each pin is operated by the air cylinder 15 and fitted into the pin holes of the movable bases 3a, 3b, 3c ---, thereby moving the movable bases 3a, 3b, 3c --- You may make it position.
[0021]
Instead of an air cylinder for the drive mechanism, a feed screw may be used, and the feed screw may be rotated by a drive motor, thereby moving the first movable base. The first movable base may be moved by another driving mechanism.
[0022]
Furthermore, although the center part 11 and the nut 12 constitute the stopper of the connecting rod 7 in this embodiment, it is not always necessary. For example, as shown in FIG. 6, a flange 16 having a constant diameter is formed on the connecting rod 7, a stopper of the connecting rod 7 is formed by the flange 16 and the nut 12, and the relative movement amount of the connecting rod 7 and the plate 8 is limited. You may make it do. Accordingly, the relative movement amount of the movable bases 3a, 3b, 3c --- can also be limited. As shown in FIG. 7, a collar 17 having a constant diameter is fitted to the connecting rod 7, and a stopper of the connecting rod 7 is configured by the collar 17 and the nut 12 to limit the relative movement amount of the connecting rod 7 and the plate 8. It may be.
[0023]
As shown in FIG. 8, a telescopic tube 18 that expands and contracts by a certain distance may be provided between the movable bases 3a, 3b, 3c ---, thereby constituting the movement amount limiting means.
[0024]
FIG. 9 shows another embodiment. In this embodiment, a plurality of belt wrappers 19 are arranged at intervals from each other. When the slit web material is wound around each winding core 2 between each winding arm, each belt wrapper 19 is wound around each winding core 2. The web material can be wound by engagement. The configuration is the same as that described in JP-A-5-17058.
[0025]
As in the winding arm 1 of FIG. 1, a plurality of movable platforms 20 are arranged in the arrangement direction of the belt wrappers 19, and each belt wrapper 19 is attached to and supported by each movable platform 20. Further, a bearing 21 is provided on the movable base 20 and fitted to the guide rail 22, and the movable base 20 is guided by the bearing 21, and the movable base 20 is movable along the guide rail 22. The guide rail 22 extends in the arrangement direction of the belt wrapper 19. Further, similarly to the winding arm 1 of FIG. 1, a plurality of movement amount limiting means are combined with the movable base 20, and each movement amount limiting means is provided between the movable bases 20. The drive mechanism such as an air cylinder is connected to the first movable base 20 in the arrangement direction of the movable bases as in the winding arm 1 of FIG.
[0026]
Therefore, as with the winding arm 1 of FIG. 1, when changing the slit width of the web material, the first movable base 20 can be moved by the drive mechanism, and the other movable base 20 can be moved by the movement amount limiting means. . Accordingly, the position and interval of the belt wrapper 19 can be adjusted in two stages to correspond to the slit width of the web material.
[0027]
When supplying the take-up core, a plurality of supply units may be arranged at intervals, and the take-up core may be automatically supplied between the respective take-up arms. A plurality of marking units may be arranged at intervals from each other, and after the web material is wound up, before the wound product is taken out, the web material may be marked such as perforation. Then, a plurality of movable bases are arranged in the arrangement direction of the supply units or marking units, each supply unit or marking unit is supported on each movable base, and each movable base moves along the guide rail.
