路内の気流の流速を高めることかできない。<Problem to be Solved by the Invention> By the way, in such a weft storage device, the airflow that enters the annular airflow passage from the airflow inlet of the annular airflow passage travels in the same direction as the rotational direction of the storage drum. Since the air flows for approximately one revolution and then collides with the air inlet, the pressure within the annular air flow passage becomes too high, making it impossible to increase the flow velocity of the air flow within the passage.
このように、環状気流通路内気流の流速を高めることか
できないことは、織機の回転数を上げられないことにつ
ながり、織機の性能向上に支障を来すという問題点かあ

ある。That is, in order to lower the pressure inside the annular airflow passage, the airflow can flow through the annular airflow passageway in the same direction as the rotational direction of the storage drum for approximately one revolution, and then be discharged just before hitting the airflow inlet. However, in the conventional configuration described above, since the storage drum is rotating, it is not possible to determine the relationship between the position of the exhaust port provided on the storage drum and the position of the fixed airflow inlet. Airflow is also exhausted from the exhaust port. Therefore, extra airflow is required to be blown into the annular airflow passage, and as a result, it is necessary to increase the capacity of the blower, etc. for airflow supply, which is a huge waste of energy. There are some problems.

The weft yarn 3 stored in the storage section 12 is pulled out, and then directly inserted into the weft without being stored in the storage section 12 via the fixed guide 23. When weft insertion is completed, the next weft is wound around the storage portion 12 of the storage drum l in the same manner as described above.
上記の作用中において、貯留ドラムlは、その端壁24

The airflow that has entered the passage 6 flows through the annular airflow passageway 6 for approximately one revolution in the same direction as the rotational direction of the storage drum l, and then passes through the exhaust port 19 immediately before colliding with the airflow inlet 18.
Since the air is discharged from the annular airflow passage 6, the pressure inside the annular airflow passage 6 can be reduced.
この結果、環状気流通路6内の気流の流速を高めること
かできるようになり、織機の回転数を上げることか可能
となって、織機の性能向上を図ることか可能となる。As a result, it becomes possible to increase the flow velocity of the airflow in the annular airflow passage 6, and it becomes possible to increase the rotational speed of the loom, thereby making it possible to improve the performance of the loom.

ルギを図ることかできる。Furthermore, according to this configuration, since the stationary holding drum 13 is fixed and the relationship between the position of the exhaust port 19 provided thereon and the position of the airflow blowing port 18 is specified, air can be removed from the necessary exhaust port 19. Since the airflow is discharged, there is no need for extra airflow to be blown into the annular airflow passage 6, and there is no need to increase the capacity of a blower or the like for supplying the airflow, and energy can be saved.
ところて、貯留ドラム1の各部の機能を検討すると、第

B部は張力か高く、表面か硬くないと摩耗する。Also, part A has a low tension and a soft surface (but does not wear out,
Part B has high tension and will wear if the surface is not hard.
従って、従来ては、貯留ドラムの表面粗さ並びに硬度等

とかできる有用性大なるものである。<Effects of the Invention> As explained above, according to the weft storage device for a shuttleless loom of the present invention, the storage drum is fixed to the rotating shaft, and the stationary holding drum is arranged on the weft insertion nozzle side of the storage drum. is attached to the rotating shaft via a bearing, and a fixed cover is provided that surrounds the outer circumferential surface of the stationary holding drum with a gap, and the stationary holding drum outer circumferential groove and the fixed cover inner circumferential groove are arranged in the same direction as the rotational direction of the storage drum. An annular airflow passage is formed in which an airflow circulating in the airflow is formed, and the weft is drawn out from the storage portion of the storage drum through a gap between the stationary holding drum and the fixed cover, while the airflow in the passageway is drawn out from the airflow inlet of the annular airflow passageway. Since the airflow that has entered the annular airflow passage is made to flow approximately once around the inside of the annular airflow passage and then is discharged to the outside immediately before hitting the airflow inlet, the pressure inside the annular airflow passage can be reduced. It becomes possible to increase the speed of the airflow in the annular airflow passage to increase the rotational speed of the loom, which in turn makes it possible to improve the performance of the loom. In addition, by discharging the airflow from the necessary exhaust ports, there is no need for extra airflow to be blown into the annular airflow passage, and there is no need to increase the capacity of a blower or the like for airflow supply, resulting in energy savings. It is extremely useful.
