Description

[Detailed explanation of the idea] The present invention relates to a small frame stopping device in an automatic reeling machine.

A small frame stopping mechanism, a first lever swingably supported by the machine frame, and a second lever pivotably supported in the middle at the tip of the first lever, A cord collector having an insertion hole through which the yarn being reeled passes through is provided at one end of the second lever, and a claw piece is provided at the other end, and the second lever is swung by a knot jammed in the cord collector. A rotary windmill that flips up the second lever and rotates the first lever is provided in opposition to the pawl piece, as disclosed in Japanese Utility Model Application Publication No. 16204/1983.

However, in this case, the small frame stop mechanism is activated only when a knot becomes clogged in the cord collector, and for some reason the grains increase.
There is no means for stopping the small frame by forcibly activating the stopping mechanism of the small frame by using other driving force when the flying density is reached.

Therefore, the applicant of the present application has previously proposed a device in which the first lever is operated by detecting the state of flying fineness.

However, in this case, since the detecting section is provided at a location apart from the first lever, not only is a means for connecting the first lever and the detecting section required, but the operation tends to be delayed to some extent. There are inconveniences in becoming one.

The purpose of the present invention is to obtain a device that does not have such inconveniences, and has a small frame stopping mechanism 1 and a first lever 3 that is swingably provided on the machine frame 2. and a second lever 4 which is swingably provided, and has an insertion hole at one end of the second lever 4 through which the yarn a being reeled passes.
A claw piece 6 is provided at the other end, and when the second lever 4 swings due to a knot clogging in the cord collector 5, the second lever 4 is flipped up and the first lever 3 is rotated. A rotary windmill 7 to be moved is provided opposite the claw piece 6, and a drum wheel 8 that locks the four reeling threads a on the first lever 3 and the drum wheel 8 are provided.
A third lever 10 is provided which is provided with a weight 9 that balances the reeling tension applied to the reeling force and which is provided with a claw piece 11 that faces the rotary windmill 7.

1 to 4, the third lever 10 is provided on the first lever 3 and pivotally supported together with the second lever 4,
A drum wheel 8 and a weight 9 are provided at one end of the lever 10, and a claw piece 11 is provided at the other end.

However, as shown in FIG. 5, it is also possible to provide a drum wheel 8 and a weight 9 on the second lever 4 so that the lever 10 can be used in common with the second lever 4.

In the drawing, reference numeral 19 indicates a slit-type fineness sensor that detects the fineness of the yarn a, and 12 indicates a welding device, and the four reeled yarns a that are spliced and turned into threads by the welding device 12 are as follows: The cord collector 5, the drum wheel 13 provided on the machine frame 2, the drum wheel 8 described above, the drum wheel 14 provided on the machine frame 2, and the tip of the tension sensing arm 15 which is a part of the small frame stopping mechanism 1. Small frame 1 after passing through the drum wheel 16 and the treadmill 17
It is wound up at 8.

The small frame stopping mechanism 1 consists of a brake wheel 21 that contacts the friction ring 20 of the small frame 18, the sensing arm 15 and a cam 15a provided at the root of the sensing arm 15, and a rocker that supports the brake wheel 21. The lower end of the movable arm 23 is pushed up by the cam 15a to normally keep the brake wheel 21 separated from the friction wheel 20, and when the sensing arm 15 is activated, the push is released and the brake wheel 21 is moved away from the friction wheel 20. Small frame 1 by touching
Stop 8.

Incidentally, when the first lever 3 rotates, the sensing arm 15 is operated in conjunction with the rotation.

Next, the operation of this device will be explained.

When the yarn a spliced by the splicer 12 is wound around the small frame 18 in a normal reeling state, the claws 6 and 11 provided on the second lever 4 and the third lever 10 are as shown in FIG. Like the ratchet wheel 7
It is kept separate from the

When one end of the second lever 4 is pulled up due to a knot in the cord collector 5, the claw piece 6 is locked to the ratchet wheel 7.

If the reeling tension increases for some reason, the drum wheel 8 side is pulled up as shown in FIG.
engage with.

Then, the lever 3 is pushed by the ratchet wheel 7 and is swung as shown in FIG.

As a result, the sensing arm 15 is pulled by the string piece 22 and tilted, and the cam surface 15a retreats from the lower end of the swinging arm 23.

Therefore, the brake wheel 21 comes into contact with the friction wheel 20 by the force of the spring 24, and brakes the small frame 18.

In this way, according to the present invention, the lever 4 provided with the cord collector 5, the drum wheel 8 and weight 9 for locking the four reeling threads a, and the claw piece provided on the second lever 4 are provided. Since the lever 10 is provided with the pawl piece 11 that engages with the rotary pawl wheel 7 facing the pawl 6,
The first lever 3 is rotated not only when the knot is jammed in the cord collector 5, but also when the yarn becomes thick and the tension of the yarn increases, and in conjunction with this, the small frame stopping mechanism 1 is operated. It is possible to
This makes it possible to prevent flying fibers, and in particular, by providing the third lever 10 on the first lever 3, it is possible to operate the small frame stopping mechanism 1 whenever the yarn tension increases. This has the effect of simplifying the structure.
