Description

[Detailed Description of the Invention] The present invention relates to a clearer device that rotates a clearer cloth provided to wipe a group of drafting rollers.

In conventional spinning machines, in order to prevent the drafting rollers from becoming dirty and the fibers from getting wrapped around them, an endless clearer cloth 1 is brought into contact with the drafting roller group 2 as shown in Figure 1 to wipe them clean. If the clearer device 3 is operated for a certain period of time, fluff and the like will adhere to the parts assembled in the clearer device 3 and must be manually removed periodically.

If left with fluff, etc. attached, the clearer roller 4 will malfunction, causing the endless clearer cloth 1 to malfunction, or temporarily stop rotating, causing the clearer roller 4 to malfunction. There is a risk that problems such as fluff accumulated on the cloth 1 will fly into the fleece 5.

In the clearer device 3, a rotating shaft 6 for rotating the clearer cloth 1 is supported by a bracket 7, and the bracket 7 must be removed or the rotating shaft 6 must be extracted from the bracket 7.
In particular, the clearer device 3 installed at the bottom of the drafting roller group 2 is surrounded by the drafting roller group 2 and roller stands related to the drafting roller group 2 (not shown), making cleaning work difficult. Cleaning work was limited to areas that were visible to the naked eye.

Further, the clearer cloth 1 must be replaced when it becomes worn or dirty, and in order to rotate the clearer cloth 1, a bearing device (not shown) such as a bearing or a one-way clutch is incorporated in the clearer roller 4. It is necessary to perform operations such as removing dirt and applying oil, and the clearer device 3 must be removed at regular intervals. Therefore,
It has been desired in terms of work efficiency that the clearer device 3 be easy to remove.

In the conventional clearer device, as shown in FIG. 2, in the clearer device 8, a notch 10 is provided in the clearer frame 9 and is supported by a pin 11, etc., and a swing arm 12 for driving the clearer roller 4 is provided. 1
3 can be separated by loosening the bolt 14, and the clearer device 8 can be removed from the spinning machine. However, since the bolts 14 of the clearer device 8 are installed in places where they cannot be seen or are separated from the work side, and where it is difficult to loosen the bolts 14, the work time required to attach and detach the clearer device 8 is significantly increased. cannot be shortened to

In view of the above-mentioned drawbacks, the present invention aims to significantly shorten the working time involved in attaching and detaching the clearer device.

To explain the embodiment of the present invention using figures, the third
As shown in Figures to Figures 7, the lower clearer device 15
A notch 23 is provided for inserting the rotating shaft 17 in the bracket 16 that supports the clearer device 15, and a notch 22 is provided in the swinging arm 19 that transmits circular arc motion, so that the clearer device 15 can be attached and detached in the direction of the arrow 18. .

Clearer roller 25 in the device 15
The protruding material 26 is fixed to the clearer frame 27 at the relative position of the working side 34, and the holder 28, which is movable in an arc, presses the protruding material 26 toward the drafting roller group 29 side using a spring or the like (not shown). Set it up so that it does. Further, a magnet may be used as the holder 28, and in that case, the protrusion 26 may have a shape that allows the magnet to easily attract it.

To explain the operation of the present invention using an example, if the holder 28 is operated in response to the pressing force of the spring, that is, moved in the direction of the arrow 31 around the shaft 30, the lower clearer device 15 is moved around the rotation shaft 17. can be moved in the direction of arrow 32. After moving to a certain extent in the direction of arrow 32, the lower clearer device 15 is moved in the direction of arrow 33 to complete removal.

Instead of providing the cutout 23 in the bracket 16 into which the rotating shaft 17 is inserted, a cutout like the cutout 10 shown in FIG. 2 may be provided in the clearer frame 27 so that the clearer device 15 can be attached and removed.

As can be seen from the above description, the clearer device according to the present invention takes an extremely short time to attach and detach, so it can be removed even during normal cleaning to quickly clean the details, extending the life of the clearer device. Not only that, but by removing it, you can inspect even the details, so any defects can be quickly discovered, and the time required for maintenance work can be extremely shortened.
