This forms an annular airflow path in the weft path in front of the weft storage drum that rotates in synchronization with the main shaft of the loom, and circulates in the airflow path in the same direction as the rotation direction of the weft storage drum. The weft is rotated by blowing an airflow into the storage drum, thereby winding the weft around the storage drum.

なる。In recent years, with the increasing speed of looms, the storing speed of wefts has also been increased. Therefore, in the case of the above-mentioned conventional weft storage device, it is necessary to increase the flow velocity of the airflow in the annular airflow passage extremely with the increase in the peripheral speed of the storage drum. For this reason, it is required that the capacity of the blower for supplying the airflow be made considerably large, and this causes a problem that the energy consumption of the motor for driving the blower increases. In addition, when the flow velocity of the airflow in the annular airflow passage is increased, the release resistance at the time of weft release during weft insertion is increased, so that the pressure and discharge amount of the weft-injection jet fluid must be increased. Have to be. As a result, the energy consumption for weft insertion is increased, and the weft is adversely affected such as damage.

In the weft storage device of this embodiment, a weft supplied from a yarn feeder (not shown) is guided onto the storage unit 20 via a feed roller (not shown). Then, the weft passes through the storage unit 20 and the holding unit 16 and the fixed cover 3.
4 is guided to the yarn guide 24 through a yarn guiding portion 38 which is a frustoconical slit, and further guided to a weft insertion nozzle via a clamper that opens and closes in accordance with the weft insertion.

The length of weft required to feed the weft is sent out. Therefore, when the weft is gripped by the clamper, the weft sent out during this time is slackened between the feed roller and the clamper, and the slackened weft is rotated by the airflow of the annular airflow channel 30 and is rotated with the rotation of the storage unit. Is stored.

1 is set so as to have a ratio of 0.4 to 0.85 with respect to the outer diameter D0 of the storage section 20 of the weft storage drum 18, so that the weft is rotated by an annular airflow having a relatively small diameter. ing. Therefore, the speed of the air flow required to obtain the angular velocity required to rotate the weft yarn at a speed equal to the peripheral speed of the storage unit 20 is reduced, and is proportional to the center diameter D 1 of the annular air flow passage 30. Can be smaller.

And the opening angle θ of the frusto-conical yarn introduction section 38 also needs to be set appropriately, but the values of both of them are 0.2 to 0 in the ratio of L 1 to the outer diameter D 0 of the storage section 20. .6, and .theta. Is preferably set in the range of 40 to 70 degrees. In other words, in order to obtain a D 1 that has been set, the only change the L 1 wishing to make a hand, occur if L 1 is too large, increase in size of the apparatus along with this, and the yarn introduction part 38 This may cause an increase in resistance when winding or releasing the weft due to an increase in the distance. If the change is made by changing only θ, θ may become too large, and the resistance to the weft at the bent portion of the storage drum 18 and the yarn guide 24 increases, and the unwinding resistance of the weft increases. May be increased. Therefore, by appropriately selecting and setting L 1 and θ within the above range, even when the center diameter of the annular airflow channel 30 is relatively reduced, stable storage and weft insertion can be performed.

In addition, the number of rotations of the air flow supply blower can be reduced, and the power consumption of the blower driving motor can be reduced.

When the ratio D 1 / D 0 is up to about 0.85, the power consumption can be considerably reduced as compared with the case where the ratio D 1 / D 0 of the related art is almost equal. It is. If D 1 / D 0 is smaller than 0.4, the difference in diameter between the storage section 20 and the annular airflow channel becomes too large, and the torque required for rotating the weft becomes large. Must be increased, and the small diameter tends to cause turbulence in the airflow in the annular airflow channel, resulting in a sharp decrease in efficiency.
