2. Description of the Related Art In particular, in the case of a planetary gear type ear assembling device, weft pulling out during weaving often causes ear breakage. For this reason, hitherto, a dropping device (dropper device) has been used to detect the occurrence of an ear break due to a weft pull-out or looseness of the weft, and when the ear break has occurred, the loom is stopped to prevent a reduction in the quality of the fabric.

[Problems to be Solved by the Invention] When trying to detect a weft drop or a loose weft with such a dropper, in the case of a woven fabric having a high density of the weft, the amount of looseness of the warp due to the collapse of the ears is large. It is possible to detect by dropper. However, in the case of a woven fabric having a low weft density, even if weft pull-out occurs, since the amount of slack of the warp is small, it is not possible to detect the break of the ear, or even if it is possible, it will be detected with a delay, and the quality of the woven fabric will be reduced. Had led to a decline.

[0004] This invention has been proposed in view of the above-mentioned prior art, and even in the case of a woven fabric having a low weft density, if a weft dropout or an ear collapse due to looseness of the weft occurs during weaving, the state of the state is considered. Is detected immediately to prevent a decrease in the quality of the woven fabric.

For this reason, in the present invention, a thin plate-like detecting piece is provided so as to be displaceable at a predetermined position of the end of the woven cloth near the weaving, and its tip is placed on the weft while being prevented from being displaced by the weft. The displacement of the detection piece caused by losing the support of the weft is detected, and an abnormality occurrence signal is output when this detection is performed.

As shown in FIGS. 3 and 4, similarly to the first embodiment, a detecting piece 1 is provided on a bracket B attached to a loom frame (not shown) at a predetermined position in the warp Y direction and at the end of the woven fabric. Installed. The detection piece 1 is pivotally supported at its upper end by a bracket B so as to be rotatable, and its lower end is placed on the weft W when the weft W is present in the woven fabric. The ear break detecting device provided on the non-yarn supply side also has a detection piece 1 which loses its support and loses its support due to its own weight when the weft is pulled out or loosened, similarly to the case where it is provided on the yarn supply side. At 4, it rotates counterclockwise. A limit switch (not shown) is provided in the vicinity of the detecting piece 1 so as to come into contact with the detecting piece 1 when the detecting piece 1 rotates. Keep it.

In the case described above, each detecting piece 1 is usually mounted on two to five wefts so as to be prevented from rotating. By changing the angle at the time of placing on the weft, it becomes a form of being placed on the predetermined number of wefts. The change in the inclination angle of the detection piece 1 is appropriately set by changing the pivot point of the detection piece 1 with respect to the bracket B up or down, or changing the length of the detection piece 1.

The contact angle between the weft on which the detecting piece 1 is mounted and the detecting piece 1 is such that the detecting piece 1 is securely mounted on the weft as shown in FIG. In order to prevent this, it is desirable that the contact angle be closer to a right angle. Therefore, in the case where the weaving of the woven fabric occurs, it is desirable to arrange the detecting device so as to be parallel to the end of the woven fabric so that the detecting piece 1 is placed at right angles to the weft. .

Needless to say, it is preferable to place the detection piece 1 on the weft as close to the front of the weaving as possible, since the detection is quicker.

In the above description, the displacement such as the rotation (vertical movement) of the detection piece 1 is detected by the limit switch. However, the present invention is not limited to this.
Alternatively, the detection may be performed using a proximity switch or a photoelectric sensor, or the conduction state between the bracket and the detection piece may be detected.

The shape of the detecting piece 1 is a thin plate, and its thickness varies depending on the weft density.
Set to a range of 3.0 mm. What is necessary is just to be able to be located between warps. Further, in the above-described embodiment, the mode of the displacement is described as one that is rotated and displaced by its own weight. However, for example, an urging force such as a spring may be used.

Further, in the above description, each detecting piece is installed so as to be inclined in the winding direction of the woven fabric. However, it is needless to say that the detecting pieces may be installed so as to be directed in the opposite direction. .

Although the ear break detecting device of this invention has been described as being provided on the yarn feeding side and the non-yarn feeding side, since the weft is usually captured by the catch cord on the non-yarn feeding side, an ear break occurs. If the number of occurrences is small, it may not be provided.

According to the invention, the displacement of the detecting piece due to the loss of the support of the weft is detected, and an abnormal (ear collapse) signal is output directly and immediately. Therefore, even in the case of a woven cloth having a low weft density, if there is a break in the ear due to a weft pull-out or looseness of the weft, the state can be detected reliably and without delay, and the loom can be stopped. The quality of the fabric can be improved. In addition, since the detection piece that can be displaced is simply configured to be placed and supported on the weft, the shape and the like of the detection piece are not limited, and it can be applied to all kinds of fabrics.
