にも及ぶ厚段に対しては、有効な解決策とならない。When a conventional loom is restarted after it has stopped due to a problem such as warp yarn breakage, a stop stage occurs in the woven fabric. Many stop stages appear as free stages due to weakening of the reed striking force. However, when weaving warp yarns with high elasticity, the warp yarns stretch while the loom is stopped and then gradually contract after weaving starts, so thick tiers may appear after a while. Conventionally, the stop tiers are The problem was resolved by changing the position of the weaving opening using the feeding device or winding device when restarting the ia machine. However, although such a measure is effective for thin steps of several picks, it is not an effective solution for thick steps of several tens of picks.
発明の目的
したがって、本発明の目的は、織機の再起動時の厚段の
発生を確実に防止することである。OBJECT OF THE INVENTION Accordingly, an object of the present invention is to reliably prevent the occurrence of thick steps when restarting a loom.

ていることを究明した。Means for Solving the Invention With the above object in mind, the inventor conducted a detailed study through trial weaving in order to experimentally clarify the cause of the occurrence of the thick steps. As a result, the above-mentioned thick corrugations are caused by the warp yarns stretching while the loom is stopped, and after the stretched warp yarns become woven fabric, they gradually start to shrink.In particular, the degree of occurrence of the thick corrugation is It was determined that this is related to the time during which the loom is stopped and the shrinkage rate of the warp yarns after weaving.

補正期間中に打ち込み密度の制御が行われていく。Therefore, the present invention sets the driving density to be coarser than the target density at the time of restart, and gradually returns the corrected driving density to the original target density, thereby increasing the thickness of the woven fabric after weaving. The stage is set so that it does not occur. Here, since the degree of occurrence of thick steps is related to the stopping time and the shrinkage rate of the warp yarns, a plurality of correction patterns can be prepared in advance in association with these factors. When weaving is restarted, the most appropriate correction pattern is selected from among these multiple correction patterns, and based on it,
The implantation density is controlled during the correction period.

This correction pattern function setting device 37 is connected on the input side to a pattern input device 43, a stop time measuring device 38, and a measuring device 39 for measuring the elapsed time after restarting the loom 1 or the number of picks as the progress state of weaving. It is connected to a density calculator 41 together with a neutrality setting device 40 on the output side.

に与えられる。On the other hand, the winding device 27 is a driving density setting device 28,
Under the set driving density, the driving density is maintained at the target density by rotating the winding motor 35 in synchronization with the rotation of the main shaft 3l and as weaving progresses. This driving density is set by the density setting device 40, and the target driving density SD is set by the density calculator 41.

縮む。このため、しばらくたってから第２図に示すよう
に、５〜１０（ｃｍ）程度の幅で厚段が現れる。During such weaving, when the loom 1 is stopped due to a warp breakage, the warp threads 2 are stretched during the stop, so that after weaving is restarted, the warp threads 2 gradually shrink in the stretched portion. Therefore, after a while, as shown in FIG. 2, a thick step appears with a width of about 5 to 10 cm.

縮み率ｋは、停止時間１，の関数として表される。FIG. 3 shows the relationship between the shrinkage rate k specific to a certain warp yarn 2 and the stop time t of the loom I. Here, the shrinkage rate represents the amount of shrinkage per unit length of the warp yarns 2. As is clear from this graph, the shrinkage rate k of the warp yarn 2 increases in proportion to the stop time t8, but after a certain time, it reaches a limit and hardly changes. Therefore, this shrinkage rate k is expressed as a function of the stop time 1,.

として設定される。Next, FIG. 4 shows the relationship between the elapsed time 1 after the restart of the loom 1, or the number of bigs P, and the density correction coefficient S. This density correction coefficient S is large in proportion to the stop time t3 in order to prevent the occurrence of thick stages, and the correction period T necessary for the correction is also long in proportion to the stop time t5, and the density This is set as a unique correction pattern that approaches the correction coefficient S=1.

密度補正係数Ｓを変化させる。During weaving, when the loom l stops due to a problem such as warp or weft stopping, the stop time measuring device 38 integrates the stop time 1 from the time of stop until restarting, and calculates it by a correction pattern function when restarting. Send it to the setting device 37. Therefore, the correction pattern function setter 37 selects one of the corresponding correction patterns based on the stop time t, and sets the density correction coefficient S together with the elapsed time after startup 1 or the big number P based on the curve. change.

に厚段は発生しなくなる。Therefore, the density calculator 41 changes the target implantation density D by the density correction coefficient S over the correction period T, and changes it to the implantation density setter 28 or the PI calculation circuit 19 as necessary.
I will give it to Therefore, the 'A weave at the initial stage of startup is given as the product of the target implant density D and the density correction coefficient S, and is set coarser than the target implant density D at the initial stage of startup, but as the elapsed time t8 passes thereafter, By the correction period T, the target implantation density D is gradually returned. As a result, when conventionally such control was not performed, a thickness step occurred due to shrinkage of the warp yarns 2 in a predetermined section from the stop position.
Since the driving density is set in advance to be coarse over the area where thick steps occur, thick steps will not occur in that area even after some time has passed after weaving.

補正は、少なくとも、巻取り側で実行されれば足りる。In the above embodiment, the feeding device 14 and the winding device 27 are electrically operated for ease of control, but they may be mechanical as long as the driving density can be changed during weaving. It's okay. Further, it is sufficient that the correction of the implantation density is performed at least on the winding side.

In addition, multiple correction patterns corresponding to the stop time of the loom can be set in advance, and when the loom is restarted, the correction pattern corresponding to the actual stop time can be selected and the driving density can be changed based on this correction pattern. In other words, the occurrence of thick steps can be prevented with even greater precision.
