Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an anti-wrap brush device for preventing yarn and dust from being drawn into the yarn guide drum in a winding machine. be.

[Conventional technology]

Generally speaking, according to the standard for winding machines,
In order to prevent yarn, dust, etc. from getting caught on the surface of the 60 or more yarn guiding drums, an anti-lap brush is attached to each drum.

[Problem that the invention attempts to solve]

However, conventionally, as shown in FIGS. 5 and 6, one brush shaft 4 is attached to the rear side of the drum, which is the opposite side of the drum cover 3 connected to the connecting plate 2 for each drum. The brush halter 6 is connected to the fixture 5 fixed to the shaft 4 by holding the rods 7 and 8, and the brush 9 is inserted and fixed, which requires a large number of parts and a complicated structure. Since the brushes are attached to the drum, it is difficult to access them, making it inconvenient to replace worn brushes, controlling the gap between the brushes and the drum, and assembling them.There are many problems, such as high production costs.

[Purpose of the invention] This invention solves these conventional problems, greatly reduces the number of parts, has a simple structure,
The purpose is to simplify the replacement work and assembly of worn brushes.

Still another object of this invention is to provide accurate and easy control of the gap between the brush and the drum.

The above objectives and other features of this invention will be expressed later.

[Means for solving problems]

In order to achieve this purpose, this invention uses the base 1
In an ordinary thread winding machine, a drum cover 14 is connected to the front surface of a thread guide drum 13 rotatably supported by a rotating shaft 12 on a rotary shaft 12 through a connecting plate 15. An elastic plate 16 is attached to the connecting plate 15 for holding the brush, and the elastic plate 16 is attached to the front side of the thread guide drum 13.
6 and the connecting plate 15, a brush 17 for preventing yarn, dust, etc. from getting caught in the yarn guide drum 13 is sandwiched and fixed.

〔Example〕

That is, in this invention, an elastic plate for pinching the brush is directly attached to a connecting plate that connects the drum cover provided on the front of the drum, and the brush is sandwiched and fixed between the connecting plate and the elastic plate on the front of the yarn guide drum. As a result, a drum cover 14 is connected to a connecting plate 15 on the front side of the yarn guide drum 13.

An elastic plate 16 for pinching brushes as shown in FIGS. 1 and 2 is fixed to the connecting plate 15 with screws or rivets, and the connecting plate 1
A brush 17 is sandwiched between 5 and an elastic plate 16.

Therefore, in this embodiment, the brush 17
Replacement and assembly of the brushes is simplified because access to the parts is easily achieved at the front of the drum cover 14 through the space between them.

3A and 3B illustrate another embodiment of this invention, in which a connecting plate 15 on the front side of the thread guide drum 13 is shown.
The elastic plate 16 to be attached to the brush is connected by configuring it as shown in FIG. When fixing the elastic plate 16 to the plate 15, the operator approaches the connecting plate 15 and the substantially U-shaped holding portion 16″ that is inserted into and supported by the elastic plate 15 at the front surface of the yarn guide drum 13. It is easy and the number of parts is greatly reduced, making brush replacement and assembly simple and convenient.Furthermore, according to another embodiment of this invention, the elastic plate is configured as a brush clipping portion and a clipping portion for the connecting plate. By providing a control screw on the bottom of the clip, the brush can be replaced and assembled even more easily, and the distance between the brush and the drum can be easily controlled.

This invention will be explained in detail below based on the drawings.

1 and 2 illustrate one embodiment of this invention, and 11 is a base of the winding machine, on which a rotating shaft 12 on which a thread guide drum 13 is attached is supported. In general, a winding machine is equipped with up to 60 or more thread guide drums according to the standard, but only a portion is shown in the drawing to avoid complexity and promote understanding.

This can only be done by being inserted from the top.

In this embodiment, the parts other than the above configuration are the same as the embodiments of FIGS. 1 and 2.
Identical parts are given the same reference numerals and detailed explanations will be omitted.

Next, FIG. 4 shows still another embodiment of this invention, in which the connecting plate 16 is composed of a brush pinching part 16' and an insertion part 16'' for the connecting plate 15, which is similar to the above embodiment. It is the same as the example, and the pinching part 1
Fix the nut 18 to the bottom of the gripper 16'', and screw the control screw 19 with the grip onto the nut 18 to tighten the gripper 16''.
It is designed to allow access to the inside.

Therefore, in this embodiment, by controlling the control screw 19, the amount of vertical protrusion of the brush 17 sandwiched between the pinching portions 16', that is, the amount of vertical protrusion of the thread guide drum 1 is controlled.
The distance to approach 3 can be controlled.

Therefore, in this embodiment, the brush 17
The gap between the brush 17 and the yarn guide drum 13 can be controlled very easily, and even if the brush 17 is slightly worn during use, the control screw 19 is used to protrude by the amount of wear, so that the anti-lap is always uniform. can perform an action.

In this embodiment, by inserting a compression spring 20 between the nut 18 and the control screw 19, so-called backlash between the screws can be prevented and accurate control can be achieved.
