Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding device in which a surface drive winding system is added to a center drive winding system multi-spindle turret type winding machine.

In order to eliminate the risk of web damage due to friction, which is a disadvantage of the surface drive winding method, and to enable high-quality winding with uniform tension even on webs that are sensitive to friction, we have developed a technology that incorporates the center drive winding method. It is publicly known. However, there were various difficulties in creating a multi-axis turret that incorporated the center drive winding method and the surface drive winding method. The winding device of the present invention (hereinafter referred to as the device of the present invention) solves the above-mentioned difficulties, and a specific example thereof will be explained using a four-axis turret type as an example. The A-side turret plate 3rB side turret plate 3, which is rotated by the turret plate rotation drive source 2 in the frame 1, is directly connected to the A-side turret plate 3 by a rotating shaft 31.

] is rotatably mounted, a surface roll 4 is rotatably disposed at the center of rotation of the turret plate 3, and a plurality of clamping mechanisms 6 for clamping both ends of the winding core 5 are connected to the rotating shaft 31. They are arranged at equally spaced positions on straight lines that intersect with each other as the center, and for each pair of the plurality of linear movement mechanisms T that enable the holding mechanism 6 to move linearly in order to follow changes in the winding diameter. The clamping mechanism 6 is connected to the clamping mechanism 6. To explain the linear movement mechanism 7 in more detail, slide rails 11 for maintaining the linear movement of the holding mechanism 6 are arranged on the turret plate 3 parallel to a straight line that intersects the turret plate 3 with its rotation axis 31 as the center. A pair of balance arms 72 which can be driven and rotated are provided on the rotation shaft 31, and the balance arm T2 and the clamping mechanism 6 movably supported on the slide rail 71 are connected via a turnbuckle 73 so as to be freely tiltable. At the same time, the rod Ba of the cylinder 8 is connected to one of the clamping mechanisms 6 of the pair.

The rotational driving force of the chuck portion 61 of the clamping mechanism 6 is transmitted from the drive device 9 to the sprocket wheel 10A,
Sprocket wheel 10B distributes rotational driving force to sprocket wheel 11A and sprocket wheel 11C, and sequentially transmits rotational driving force to sprocket wheel 11B and sprocket wheel 12A, and to sprocket wheel 11D and sprocket wheel 12B. The chuck portion 61 that holds both ends of the winding core is rotated.
The drive device 9 described above drives two of the four axes, and the other two intersecting axes transmit rotary driving force to the drive device 9 on the B side in the same way as on the A side.

], the surf roller 4 has a drive motor 17 and a chain 2.
0 and sprocket wheels 18 and 19. In addition to the above-mentioned configuration, a tatsuchi roll mechanism 22 that can drive the web supply mechanism 21 rotation, a cutting mechanism 23, a core pressing mechanism 24, a core supply mechanism 25, and a back-up roll mechanism 26 are added to realize completely automated winding. The device is configured. To explain the operating mechanism of the device of the present invention, a web is applied to the surface of the Surf S-roll driven in synchronization with the web speed through the Unib feeding mechanism 21, and the web is pressed against the surface of the Surf S-roll by the Tatsuchi roll mechanism 22 as the web slides on the surface of the Surf S-roll. It is prevented.

A predetermined contact pressure is applied to the rotated and driven core 5 in the direction of the rotation center of the Surf S roll 4 by the core pressing mechanism 24, and tension is applied to the web by the rotational driving force of the core 5. , the web is wound around the winding core 5, and when a certain amount of the web is wound around the winding core 5, the turret plate 3 is rotationally driven to move the second winding core 51 from the position c to the position a, and the web is wound around the winding core 5. Continue the preparation work.

As this winding operation progresses and the winding diameter of the second winding core 51 becomes larger, the bottom chamber (not shown) of the cylinder 8 of the linear movement mechanism 7 is filled with the winding diameter according to the size of the winding diameter. By feeding pressurized air and pushing out the rod 8a, the clamping mechanism 6 moves linearly on the slide rail 71, and the balance arm 72 rotates to move one clamping mechanism 6 according to the winding diameter. By moving it in a straight line, it is possible to follow changes in the winding diameter. In addition, when winding up a wide web or a web with a large winding diameter, the web is wound around the winding core 5 while being assisted by the back-up roll mechanism 26.

When the predetermined length has been wound, a new core 5 is supplied to the clamping mechanism 6 by the core supply mechanism 25, and then pressurized air is sent to the rod chamber (not shown) side of the cylinder 8. Therefore, at the same time as the winding core 5 is brought into contact with the surf-s roll surface, a predetermined contact pressure is applied to the winding core 5 by the winding core pressing mechanism 24, and the web is cut by the post-cutting mechanism 23 to finish winding the web. The material to be wound at the position of and a is removed together with the winding core 51, a new web is wound around the new winding core 5, and the above-mentioned process is reversed to proceed with the winding operation. Since the device of the present invention is formed into a turret as described above, clamping mechanisms are disposed above and below in the vertical direction, so that it is difficult to adjust the contact pressure during the winding operation in the vertical direction.

However, by connecting the above-mentioned clamping mechanism to both ends of the balance arm, it is possible to balance the weight and easily adjust the contact pressure during winding. It is possible to realize a multi-axis turret, which improves the efficiency of winding work and even when handling extremely long items.
In addition to improving the quality of the turret, by providing a rotationally driven tatsuchi roll mechanism, it is possible to prevent various phenomena such as air film entrainment, misalignment, wrinkles, and neck-in when the turret rotates. The effect is extremely large.
