［産業上の利用分野コ
本発明は機台停止に起因する織段の発生を防止する方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for preventing the occurrence of weaving steps due to machine stoppage.
［従来の技術］

段発生を防止するには機台再起動時に織前位置の調整を
行なう必要がある。[Prior art] Appropriate tension of the warp threads sent out from the warp beam can be maintained by controlling the warp delivery speed, and the occurrence of weaving rows during weaving can be relatively easily prevented. To prevent this, it is necessary to adjust the loom position when restarting the machine.

になっている。A device for this purpose is disclosed in Japanese Unexamined Patent Publication No. 62-53452. In this conventional device, the loom drive motor and the loom position correction motor are operatively connected to the surface roller via a differential gear mechanism, and when the loom is restarted, the loom position correction motor is activated to correct the loom position. The position is now corrected.
これにより機台再起動時の筬打ち力不足に起因する織段
発生防止が図られる。This prevents weaving steps from occurring due to insufficient reed beating force when restarting the machine.
［発明が解決しようとする課題］
しかしながら、この織前位置補正は機台再起動前にのみ
行われるため、機台再起動後の回転回数毎に異なる適正
な織前位置補正に準し得るような一括した織前位置補正
を行なうことが困難である。[Problems to be Solved by the Invention] However, since this loom position correction is performed only before restarting the machine, it is necessary to make appropriate loom position correction that varies depending on the number of rotations after restarting the machine. Therefore, it is difficult to perform a complete correction of the position of the woven fabric all at once.
そのため、適正な織前位置補正の向上を図ることができ
ず、−層効果的な織段発生防止作用を達成することがで
きない。Therefore, it is not possible to improve the proper correction of the weaving cloth position, and it is not possible to achieve a layer-effective effect of preventing the occurrence of weaving steps.
特開昭５９−５３７４６号公報には′４′６機運転中の
緯糸密度を可変制御する装置が開示されているが、機台
再起動時の織段発生に関しては何等言及されていない。Japanese Unexamined Patent Publication No. 59-53746 discloses a device for variable control of the weft density during machine operation, but does not mention anything about the generation of weaving rows when restarting the machine.
［課題を解決するための手段］
そのために本発明では、機台再起動後、機台回転速度が
定常回転速度に達するまでの間の機台回転回数を検出し
、定常回転速度に達するまでの各機台回転回数に対応し

転回数毎に遂行するようにした。[Means for Solving the Problems] To this end, the present invention detects the number of machine rotations until the machine rotation speed reaches a steady rotation speed after restarting the machine, and detects the number of machine rotations until the machine rotation speed reaches a steady rotation speed. The correction operation of the swath position correction amount set corresponding to the number of rotations of each machine table is performed for each number of rotations of the detection machine table.
［作用］
機台再起動後の機台回転回数が検出される毎にこの検出

、−層効果的な織段発生防止作用が得られる。[Operation] Every time the number of times the machine has been rotated after restarting the machine is detected, the cloth sleeve position is corrected in accordance with the set cloth cloth cloth position correction amount corresponding to the detected number of rotations. As a result, an appropriate weaving cloth position is corrected each time the machine is rotated after the machine has moved, and an effective effect of preventing the occurrence of weaving steps can be obtained.

The rotational speed of the delivery motor 1 is controlled based on the warp beam diameter calculated from the detection signal from the controller, the initial warp beam diameter, and input data such as the Mi weave of the textile. This controls the warp tension during normal operation and prevents the occurrence of weaving steps. The loom control computer C is the start switch 18
The forward rotation operation of the feed-out motor 1 is commanded based on the ON signal from the feed-out motor 1, and the rotation speed of the feed-out motor 1 is controlled by feed hack control based on the rotation speed detection signal from the row encoder 1a incorporated in the feed-out motor 1. .

The loom control computer C commands the operation of the take-up motor 20 based on the ON signal from the start switch 18, and the operation of the take-up motor 20 based on the rotational speed detection signal from the row reel encoder 20a built into the take-up motor 20.

The feed motor 1 starts up at a curve C shown in FIG. 2 and reaches the normal rotation speed V in synchronization with the machine drive motor.

In response to the first origin signal, the loom control computer C commands a corrected rotational speed preset by the input setting device 16 as the rotational speed of the take-up motor 20 at the time of the second beating.

（＝Ｏ）から変位する。Every time the origin signal is transmitted from the second time onward, the loom control computer C responds to the origin signal input and sets the corrected rotation speed V as the rotation speed of the winding motor 20 at the time of the next beating.
i (i-2 to n, n=5 in this embodiment) is commanded. As a result, the rotational speed of the take-up motor 20 approaches the chain line curve C3 while drawing the curve C2 in FIG. Curve C3 is the characteristic when synchronized with rise curve C1 of feed motor 1. The corrective rotation of the winding motor 20 is performed between the second and fifth machine rotations after restarting the machine, and the normal rotational speed ■o is reached at the sixth rotation. Due to this correction rotation, the position of the cloth front W1 of the woven fabric W is changed to the curve C4 in FIG.
As shown in the normal rotation of the loom, the normal position δo

ピュータＣは検出機台回転回数の初期化を行なう。When the number i of inputting the origin signal reaches five, the V& machine control computer C initializes the number of rotations of the detection machine table.

し、織前位置の最適補正により機台再起動後の筬打ち力
不足が適正に補償される。The method of correcting the reed position every time the reed of the weft after restarting the machine makes it possible to set the optimal weaving position for each reeding. The lack of hitting power is appropriately compensated.

をさらに進めることができる。Therefore, the accuracy of compensating for insufficient beating force in the weaving step prevention function of this embodiment is extremely high compared to the batch correction before restarting the machine, and the weaving step prevention is performed even more effectively. In order to solve the lack of reed beating force when the machine stand starts up, a method that temporarily applies overvoltage to the machine stand drive motor to obtain a sudden start-up characteristic prevents the occurrence of weaving steps at high speed rotation (approximately 800 rpm or more). Although this is not possible, the weaving bed correction for each beating of the present embodiment can reliably prevent the occurrence of weaving steps, and further increase the speed of the loom.

Alternatively, both motors may be controlled for correction rotation at the same time.

This provides an excellent effect in that the correction accuracy is increased, and thereby a more accurate weaving step prevention effect can be achieved.
