Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a waste thread discharge device for an automatic winder.
Particularly, the present invention relates to a waste yarn discharge device for an automatic winder having a waste yarn box for storing waste yarn discharged from the automatic winder, and capable of automatically discharging to the outside the waste yarn stored in the waste yarn box.

[Conventional technology]

Generally, in a winder that forms a thread package, waste yarn is generated during yarn splicing, and this waste yarn must be discharged from the winder to the outside.

Therefore, a suction duct is connected to the winder, and a waste yarn box for storing waste yarn sucked and transferred from the winder is connected to the suction duct. A filter for capturing waste threads is provided in the waste thread box, and the waste threads captured by this filter fall and are stored at the bottom of the waste thread box.

[Problem that the invention attempts to solve]

By the way, when waste thread accumulates in the waste thread box,
The waste yarn box is equipped with a lid to open the waste yarn box, and this lid is periodically opened to discharge the waste yarn inside the box to the outside. Therefore, in the past, the waste thread box had to be inspected regularly, and if this was not done, a large amount of waste thread would accumulate in the waste thread box, resulting in a decrease in the suction power for sucking the waste threads. .

In addition, in order to discharge the waste threads from inside the waste thread box to the outside, the inside of the waste thread box must be opened to the atmosphere, creating the problem that the equipment must be stopped.

The present invention was created to effectively solve the above problems.

The present invention is a waste thread discharge device for an automatic winder that has a waste thread box for storing waste threads sucked from the winder, and the waste threads in the waste thread box can be constantly discharged to the outside, thereby saving labor and sucking the waste threads. An object of the present invention is to provide a waste yarn discharge device for an automatic winder that can maintain a constant suction force.

[Means and actions for solving problems]

The present invention provides a waste yarn discharge device for an automatic winder, which is connected to a suction duct extending from an automatic winder and has a waste yarn box for storing waste yarn discharged from the winder. A waste yarn dispensing means is formed, and includes rotary bodies that are brought into contact with each other and pressed against each other to close the discharge port, and that the rotary bodies are rotationally driven to let out the waste yarn from the press-contact portion to the outside. The waste threads stored in the waste thread box fall freely and are collected at the discharge port, and a waste thread feeding means is provided at the discharge port to close the waste threads. The waste threads in the waste thread box are discharged to the outside while maintaining a constant suction force.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Fig. 1, a suction duct 1 is connected to the winder for discharging waste yarn generated during yarn splicing to the outside, and an intake blower 2 is connected to this suction duct 1. .

In addition, the suction duct 1 has a waste thread box 3.
will be provided.

This waste yarn box 3 has an inlet 4 connected to the suction duct 1 and an outlet 5 connected to the intake blower 2. A filter 6 is disposed between the inlet 4 and the outlet 5. A filter 6 is provided in which the air flow passes and waste threads 7 discharged from the winder through the suction duct 1 are captured.

Particularly in the present invention, the bottom of the waste thread box 3 is provided with an inclined part 9 whose diameter is gradually reduced, and an outlet 10 for discharging the waste thread 7 to the outside is formed. Waste thread payout means 1 for closing this and paying out waste thread 7 to the outside
1 is provided.

As shown in FIG. 2, this waste yarn delivery means 11 is constituted by a rotating body consisting of a driving roll 12 and a driven roller 13 that are supported in parallel butt against each other, and these rollers 12 and 13 are pressed against each other. The discharge port 10 is configured to be closed by the discharge port 10. Further, the drive roller 12 is connected to a drive motor 14, and its rotational driving force is transmitted to the driven roller 13. That is, these rollers 12 and 13 are driven to rotate in opposite directions,
The waste yarn 7 in the waste yarn box 3 is drawn into the pressure contact portion 15 and is drawn out to the outside.

Specifically, each roller 12, 13 is covered with a rubber material, and the roller 12, 13 and the discharge port 1 are covered with a rubber material.
0 and the opening line portion 16 are sealed with resin materials 17 and 18, and these resin materials 1
7 and 18 are biased by springs 19 and 20, etc.

The waste threads 7 discharged from the waste thread box 3 are discharged into a receiving box 21 which is opened upward.

Next, the effect will be explained.

As shown in FIG. 1, waste yarn 7 generated during yarn splicing in a winder is introduced into a waste yarn box 3 through a suction duct 1.
It is captured by a filter 6 provided inside.
The waste threads 7 captured by the filter 6 fall under their own weight, are collected along the slope 9 formed at the bottom 8 of the waste thread box 3, and are guided to the discharge port 10.

In this discharge port 10, a driving roller 12 and a driven roller 13 are rotated while being pressed against each other, and the waste threads 7 collected at the discharge port 10 are drawn into the pressure contact portion 15, and the waste threads 7 are transferred to these rollers 12. , 13 and is fed out of the waste yarn box 3. Further, since the rollers 12 and 13 are pressed against each other to close the discharge port 10, the suction force of the suction duct 1 is maintained constant without decreasing.

In this way, the present invention has the bottom part 8 of the waste thread box 3.
By forming a discharge port 10 for discharging the waste thread 7 in the machine and providing a waste thread delivery means 11 for closing the discharge port 10 and discharging the waste thread 7 to the outside, the waste thread 7 can be automatically discharged at all times. Labor saving can be achieved.

Furthermore, since the discharge port 10 is closed, the suction force within the suction duct 1 is not reduced.

In addition, in the above embodiment, the waste yarn feeding means 1
A pair of rollers 12 and 13 were adopted as 1, but
The present invention is not limited to this, and in other embodiments, the waste yarn delivery means 11 may be configured by a pair of belts.

In this case, the belts are pressed against each other to close the discharge port 10, and
It is driven to discharge the waste yarn 7 from the pressure contact portion.

[Effect of idea]

In summary, the present invention exhibits the following excellent effects.

(1) A discharge port is formed at the bottom of the waste yarn box, and a waste yarn delivery means is provided to close the discharge port and discharge the waste yarn inside the waste yarn box to the outside, so that the waste yarn is always automatically discharged to the outside.
