Abstract

PURPOSE:To prevent generation of creases and involving of air by mounting a plurality of pressing devices on a second turret turned in one body with the rotation of a main body turret of a multiple spindle turret winder in the direction opposite to the rotation. CONSTITUTION:A circular main body turret 1 having a plurality of take-up shafts 3a-3d (four in the drawing) on the peripheral portion thereof is rotated by a driving shaft 2 mounted at the center thereof, and is provided with a second turret 5 disposed separately from the main body turret 1 in such a manner as to interlock with the turret 1 and turn in the opposite direction. The second turret 5 is provided with a plurality of pressing devices 4 in which an arm 4b having a pressing roller 4c at the forward end is pivoted outwardly by the operation of a fluid pressure cylinder 4a. The pivotal points of arms 4b of the pressing devices 4 meet at right angles each other about a driving shaft 6 of the turret 1.

Description

[Detailed Description of the Invention] The quality of the rolled product is improved by eliminating imperfections in the contact pressure during retrieval.
This invention relates to a multi-spindle turret winder aimed at improving yield.

The contact pressure device of a conventional multi-spindle turret winder is explained with reference to Fig. 1. There are four windings on the main body side turret (1)! ? ++
In a multi-shaft turret winding machine in which the main body side turret (1) is rotationally driven by the rotary drive shaft (2), the fluid pressure cylinder (4a)
, an arm (4.b), and a contact pressure device (4) consisting of a contact pressure loaf (4C) to tilt the arm (4b) by the extension motion of the rond (4a') of the fluid pressure cylinder (4a), The pressure roller (4C) is configured to move toward and away from the winding shaft (3a). In such a configuration, the contact pressure device (4) works effectively for winding in a fixed position, but when the main body side turret (1) starts rotating. There was a drawback that the contact pressure device (4) was effectively plowed.

Then, there is also a configuration in which the baton is passed to the next pressure contact device (4). In this case, the timing of switching the contact pressure of the two contact pressure devices (4) is very difficult, and there is a drawback that wrinkles occur due to air entrainment.

Multi-shaft turret winding machine of the present invention (hereinafter referred to as the present invention)
This is a configuration in which all the plurality of contact pressure devices are disposed on the second turret 1-, which is rotated in the opposite direction to the rotational direction, integrally with the rotational drive of the main body side turret of the multi-shaft turret winder. The defects have been removed.

An embodiment of the present invention will be explained with reference to FIGS. 4 and 5. The winding shaft is provided at the center of a circular main body side turret (1) having four winding shafts (8a) to (8d) arranged around one winding shaft. rotary drive shaft (2
) In a multi-spindle turret winding machine in which a main body side turret 1) is rotationally driven, the main body side turret (1) is rotated in a direction opposite to the rotation direction. The second turret (
5), and a pressure device (4) is provided on the second turret (5).
Place multiple .

The contact pressure device (4) consists of a fluid pressure cylinder (4a), an arm (4b), and a contact pressure o-7 (4c), -y-
The system (4b) is pivotally connected to the second turret 5). These multiple pivot points are the rotation of the second turret (5)
The rods (4a' of the fluid pressure cylinders (4a)
) is connected to the intermediate part of the arm (5b), and the arm ( 4b) and the position of the winding shaft (3a) is changed due to the rotational drive of the main body side turret (1).
The new take-up shaft (8a) is brought into contact with the pressure roller (4C) as shown in FIG. (8
The structure is such that it can also be pressed against b).

Another embodiment will be explained with reference to FIGS. 6 and 7.

Four winding shafts (8a) (8b), (8c), (ad
) is installed on the main body side turret (1), which is connected to the rotational drive shaft (2
), the second dam (4e) 9
A first arm (4d) is provided with a pair of contact pressure loafs (4C) at both ends, and one end is rotatably connected to the intermediate part of the second arm (Φe), and the other end is rotatably connected to the fixed end. The first arm (4d) is connected to the rod (4a:) of the fluid pressure cylinder (4a), and the second arm (4d) is connected to the rod (4a:) of the fluid pressure cylinder (4a).
A drive source (4f) for rotating the drive source (4e) is provided, and the drive source (4f) rotates the drive source (4e).
Even if the position of the winding shaft (3a) changes due to the rotational drive of the main body side turret (1) due to the extension of the rod (4a') of the fluid pressure cylinder (4a), 7th
The structure is such that it can follow the direction shown in the figure and maintain contact pressure while also being able to contact the new winding shaft (8b).

As described above, the present invention provides a contact pressure device equipped with a plurality of contact pressure rollers on the second turret that is reversely driven in synchronization with the rotational drive of the main body side turret, and instead of switching the contact pressure, nine individual pressure rollers are provided. By sequentially applying pressure to the winding shaft, it is possible to prevent wrinkles and air entrainment that occur during contact pressure cutting and changeover, and to bring about practical effects such as improving the variety of products to be wound and improving the yield.
