DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifter pressure adjusting mechanism for a lifter of a winding device.

[0002]

2. Description of the Related Art Conventionally, a mechanism for adjusting a lifter pressure in a winding device is constructed as shown in FIG. 7, and is configured by rotating a lifter pressure adjusting bolt 71 provided inside a central portion of a lifter plate 70 below. The lifter pressure adjusting bolt is displaced with respect to the lifter plate support plate 72,
The spring pressure of the lifter pressure adjusting spring 73 is adjusted.

To adjust the lifter pressure, the waterproof plug 75 screwed into the adjustment hole 74 formed in the center of the lifter plate is removed, and a tool is inserted from the adjustment hole 74 to adjust the lifter pressure. After adjustment of the bolt, the waterproof plug must be screwed in again after the adjustment, which is troublesome. Further, since the space between the seaming chuck and the seam chuck is narrow, the workability is poor and the skill is required.

After the lifter pressure is adjusted, a lifter pressure measuring device is sandwiched between the lifter plate and the chuck, and the adjustment result is measured. However, since the adjustment mechanism is located at the center of the lifter, a single adjustment is satisfactory. If you get no results,
It was necessary to remove the measuring instrument, adjust again, and attach the measuring instrument again, which was very troublesome and took a long time. Since the lifter pressure can be adjusted only for each head, a large amount of time is required as the number of heads of the winding device increases.

The lifter pressure is adjusted to the state. Therefore, if the pinions of all the heads are moved to the connecting position, the same lifter pressure is adjusted for all the heads simultaneously by adjusting one head.

In addition, if the connecting gears for connecting all the heads and the pinions meshing with the connecting gears are not provided, the load applied to each lifter pressure adjusting ring becomes lighter, so that the lifter pressure adjusting ring can be easily rotated directly or manually by a tool. The lifter pressure can be adjusted more easily for each head. At this time, the outer peripheral surface of the lifter pressure adjusting ring is configured to be a rough surface such as a knurl, so that it can be more easily rotated.
