Description

[Detailed Description of the Invention] The present invention relates to the configuration of a clearer device applied to a spinning machine provided with multiple rows of drafting rollers, and in particular, the clearer device is in contact with the lower part of a group of drafting rollers and is integrated with the drafting roller of each staff. The present invention relates to a structure of a contact holding device of a clearer device, which is configured as follows and is held in contact with the clearer device.

Conventionally, various clearer devices have been used in the drafting roller group of spinning machines, and proposals have also been made.

Particularly in roving frames and fine spinning machines, if the clearer device does not work reliably, winding and thread breakage will occur frequently, making operation difficult.

Furthermore, since these clearer devices separate and clean the fibers adhering to the drafting roller, it is necessary to remove the collected fibers at a very regular interval.

Therefore, it is required to be arranged so as to act reliably on the drafting roller and to be easy to attach and detach.

The inventor of this invention has focused on these clearer devices for over 10 years and has developed new methods and devices one after another.
provided to the industry.

One type of this type is the part that is in contact with the lower part of the drafting roller group and is divided between the roller stands.
There is a device in which an Amen Scryer device is integrally formed with a group of rollers (formed by 4 to 8 spindles) and is pivotably supported and held under pressure (Utility Model Publication No. 4624654).
.

The clearer device to which this idea is applied has attracted attention and has come to be widely used because it is easy to handle and ensures reliable contact with the rollers.

However, the abutting and holding means of the clarifier is such that the rice, which is biased on both sides, engages with protrusions protruding from the inside of the roller stand, and the clarifier is detached from the drafting roller. In some cases, it was necessary to operate the rice on both sides, and it was necessary to use one hand to operate one side at a time, and to use both hands at once, so there was a need for something that could be operated at the same time for some operations.

In addition, if these clearer devices are not designed to be thin as a whole, the airflow for cleaning will be obstructed, increasing the amount of fluff, and will also become a nuisance when cleaning by hand.

It has been desired to develop a clearer device that can be removed from these devices all at once, is thin, and operates reliably.

The present invention has been made with attention to these points, and in particular, the holding means is improved so that it can be removed from the roller group all at once with one hand, and the entire clearer device is made thin. It is.

The present invention will be explained in detail below based on the drawings. The figure shows an example in which it is applied to a two-apron, five-line drafting device in the drafting section of a spinning machine, and one staff is composed of six spindles. This is shown as a representative example, and can be similarly applied to the drafting section of other spinning machines or drafting devices with other configurations.
The number of weights can also be freely selected.

In addition, the drawings show specific configuration examples, and the present invention is not limited to the illustrated examples.
The same effect can be achieved by changing the shape or design of the component parts.

Although any suitable means can be used as the biasing device, the figure shows a structure in which an angle bracket 22 is mounted within the frame 9, and a coil spring 23 is supported on a spring support seat 22' formed on the other side of the bracket 22. Then, the coil spring 23 is inserted into the bottomed hole 24 formed in the corresponding portion of the operating rod 20.

Therefore, the operating rod 20 is always biased forward in the insertion and sliding hole 21, and can be operated by hand or by a locking member 27, which will be described later.
can be retreated as shown by dotted line 20'.

Further, the operating rod 20 is formed to be long in the width direction of the clearer device 1 (drafting roller axial direction), and regulators 25, 25 are provided inside the frames 9, 9 to maintain the position.

Also, the front clearer roller 11 supported by the fitting groove 29
The shaft 11' is resiliently supported by a push-up spring 28 that is pre-arranged in the groove 29, and the spring 28 is configured to prevent the shaft 11' from coming out of the fitting groove 29.

28' is a support shaft of the push-up spring 28.

The front clearer roller 11 also has a clearer device 1.
A clearer apron 13, 14 is provided on the circumferential surface of the clearer apron.

The other end of the clearer apron 13 and 14 is covered with the rear clearer roller 12, and the clearer roller 12 has its shaft 12' fitted into the fitting groove 36' of the support bracket 36 attached to the frame 9. and hang the clearer apron 13.14.

The clearer aprons 13 and 14 can be configured for a single spindle, for a foot spindle, or by a combination of these, but the figure shows an apron 14 for two spindles in the center of the clearer device 1, and aprons for one spindle on both left and right sides. 13 is shown in a double row configuration.

The clearer aprons 13 and 14 stretched in this manner need to be supported so as to come into contact with the bottom drafting roller group 2, and also need to be actively rotated.

For these purposes, the illustrated example is provided with a front tension bar 15 and a rear tension bar 16, which bars 15.
16 are formed with a length spanning the width direction of the clearer device 1, and guide the apron so as to push it up from the inside of the clearer apron.

These bars 15 and 16 are connected to fitting grooves 29' formed in the frame 9 and brackets 3 attached to the frame 9, respectively.
As a means for positioning and holding the tension bars 15 and 16, engagement holes 32 and 32 are formed in the handles of the tension bars 15 and 16, respectively, and plates are provided in the corresponding parts of the frame 9. Attach the spring 30°35.

Note that these can be modified and installed as appropriate.

Also, the front tension bar 15 has an apron guide 15'.
The aprons 13 and 14 are fixedly attached or integrally formed.
to guide you.

In addition, as the means for driving the clearer apron, any suitable conventionally known means can be selected, but especially in the hooked swing type of the present invention, it is possible to select a means for driving the clearer apron. It is recommended that the pawl member rotates a ratchet fixed to the clearer roller.

Moreover, it is preferable that these drives are rear roller rollers formed with a large diameter.

Therefore, in the illustrated example, the ratchet 17 is fixed to a part of the shaft 12' of the rear clearer roller 12, and the claw member 18 is press-fitted to the non-drafting part of the back roller 2' in the bottom drafting roller group 2. The ratchet 17 is intermittently rotated clockwise (FIG. 3) by the protrusion of the pawl member 18 to rotate the clearer ebrons 14 and 13.

Note that these ratchets 17 are provided with plate springs 19 for preventing reverse rotation and for braking.

In addition, in the inventive clearer device applied to such a drafting device, the front clearer roller 11 comes into contact with the bottom apron of the front apron drafting device, and if the contact pressure is strong, the There is a possibility that rotation may be inhibited.

Therefore, space rollers 37, 37 are attached to both sides of the clearer roller 11, and when the outer periphery of the roller 37 comes into contact with the non-drafting part of the bottom apron drive roller, the bottom apron and Kunoyara apron of the drafting device are connected. 0 to Q, configured to maintain a gap of 5 mm to prevent pressure contact.

Note that even if this gap is Q, 5 mm, the bottom f is 0.
The fibers that adhere to the iron are floating, so they can be thoroughly cleaned.

In this way, the locking members 27 and 27 are respectively attached to the inside of the roller stand 4 on which the clearer device 1 is installed, and the mounting position is such that the operating rod 20 of the clearer device 1 rotates around the support shaft 8. and at a position where the clearer apron 13,14 is provided on the bottom drafting roller group 2 as described above, with the operating rod 20 climbing over and being supported by the locking member 27. be.

Therefore, the locking members 27, 27 serve as supporting members for the clearer device 1, and the position is regulated by the mounting position.

Then, by pushing the operating rod 20 rearward, it is possible to release the engagement with the locking members 27, 27, and as a result, the clarifier device is suspended from the support shaft 8 and swings freely, allowing cleaning or cleaning of the clarifier. can remove the clearer device.

In addition, when installing the clearer device, by simply pushing up an appropriate part of the clearer device, the operating rod 20 will be able to overcome the locking members 27, 27 and be supported thereon.

For these reasons, it is preferable that the locking portion of the locking member 27 is a round shaft, and that both ends of the operating rod 20 form inclined surfaces 26,26.

It should be noted that these locking members 27 may have other shapes, or may be formed in such a way that the direction in which the operating rod 20 crosses over is in the opposite direction, and in such a case, the biasing spring 23 is provided in the opposite direction.

Since the clearer device of the present invention is formed in this manner, (1) the clearer device can be constructed with a thin wall, and the space in the drafting section can be widened;

(2) It is extremely easy to handle and operate.

(3) The mounting position can be determined and leaning can be performed reliably.

Effects such as this can be obtained.
