【考案の詳細な説明】
この考案は箔糸が緯入れ装置によって織口に通された後
、織り込まれるまでに箔糸の表裏が正常な状態に織口に
通されているか否かを事前に検知する箔糸表裏確認装置
を提供するものである。[Detailed explanation of the invention] In this invention, after the foil yarn is passed through the weaving opening by the weft insertion device, it is checked in advance whether the front and back sides of the foil yarn are passed through the opening in a normal state before being woven. The present invention provides a foil yarn front and back confirmation device that detects the front and back sides.
織物の緯糸に使用される箔糸はその表裏両面が平面状形
態をした線条体であって、表面に色柄が付き、裏面は白
い紙のｉｔＯものである。The foil yarn used as the weft of the fabric is a filament whose front and back sides are planar, with a colored pattern on the front side and a white paper itO on the back side.
このような箔糸が緯入れ装置によって織目に通されると
きその表裏が反対になって通されてその１１織り込１れ
ることがある。When such a foil yarn is passed through a weave by a weft insertion device, it may be passed through with the front and back sides reversed and woven into the fabric.
このような場合には織上つた織物は当然に不良品となる
。In such a case, the woven ivy fabric naturally becomes a defective product.
従って箔糸が緯入れ装置によって織目に通された後、織
り込１れる１でに箔糸の表裏が正常な状態に織口に通さ
れているか否かを事前に検知して箔糸の表裏を確認する
必要がある。Therefore, after the foil yarn is passed through the weave by the weft insertion device, it is detected in advance whether the front and back sides of the foil yarn are passed through the weaving opening in a normal state before the weaving process. You need to check the front and back.
従来この箔糸の表裏の確認は専ら作業者の眼によって判
断していたが眼に非常に疲れるために、この考案の考案
者は箔糸における表面と裏面との外観の違いにより反射
光線反射光量が相違することに着目して織目に通された
箔糸に光線を照射する方法によって検知するようにした
装置を案出した。Conventionally, the operator's eyes were the only way to check the front and back sides of the foil thread, but this was very tiring for the eyes, so the creator of this idea decided to check the amount of reflected light by checking the difference in appearance between the front and back sides of the foil thread. Focusing on the difference between the two, we devised a device that detects the difference by irradiating a light beam onto the foil thread threaded through the weave.
係る装置は織目に通された箔糸を中心にして、箔糸の下
方に発光器と受光素子とを対称的に配置して、箔糸平面
に対して発光器から光線を斜め方向に照射しそして箔糸
平面から斜め方向に反射する光線を受光素子で受光する
ようにした装置であって、金属光沢面か、白い紙面（無
光沢面）の箔糸裏面かによって反射光量が太き（異なる
ことに基き、その反射光量の差異を以って箔糸の表裏を
検知しようとしたものである。In such a device, a light emitter and a light receiving element are arranged symmetrically below the foil thread, centering on the foil thread threaded through the weave, and the light beam from the light emitter is irradiated diagonally to the plane of the foil thread. This device uses a light receiving element to receive the light that is reflected diagonally from the plane of the foil thread, and the amount of reflected light varies depending on whether it is on the metallic shiny surface or on the back side of the foil thread, which is a white paper surface (matte surface). Based on the difference in the amount of reflected light, the attempt was made to detect the front and back sides of the foil thread.
しかしながら係る装置では、織目に通された箔糸が傾い
ている場合箔糸が不正常な状態（表裏が反対の状態）に
織目に通されていても受光素子には整反射光による反射
光が大量に入らないことになる。However, in such a device, if the foil thread passed through the weave is tilted, even if the foil thread is passed through the weave in an abnormal state (front and back sides are reversed), the light receiving element will receive the reflected light due to regular reflection. It won't let in a lot of light.
斯くしてその場合の受光素子が受光している光が箔糸が
不正常な状態のときのものであるか、或いは箔糸が正常
な状態のときの白い紙面による乱反射光によるものであ
るかを判別することが困難な状態が生じて検知が不正確
になる問題があった。In this way, whether the light received by the light-receiving element in that case is the one when the foil thread is in an abnormal state, or the light that is diffusely reflected by the white paper surface when the foil thread is in a normal state. There was a problem that a situation occurred where it was difficult to discriminate, resulting in inaccurate detection.
そこでこの適業は織口に通された箔糸の状態如何にかか
わらず箔糸の表裏を常に正確に確認することができるよ
うにすることを目的とする。Therefore, the purpose of this work is to make it possible to always accurately check the front and back sides of the foil threads, regardless of the condition of the foil threads threaded through the weave.
つぎにこの考案を、図面に示す一実施態様に基いて説明
する。Next, this invention will be explained based on one embodiment shown in the drawings.
第１図に示すように、箔糸１が織目に通されたとき、耳
の外側に出ている箔糸ｌ端部分の下側に、箔糸１の下面

、そして発光器２は箔糸面に対して斜下六の位置に、ま
た受光素子４は箔糸面に対して直下位置に夫々配置され
るのである。As shown in Fig. 1, when the foil thread 1 is passed through the weave, a light 3 is projected onto the lower surface of the foil thread 1 on the lower side of the foil thread l end portion that is exposed outside the selvage. A light emitter 2 and a light receiving element 4 that receives reflected light from the lower surface of the foil yarn 1 are installed on the left and right sides of the loom, and the light emitter 2 is positioned diagonally downward with respect to the foil yarn surface. They are each placed directly below the surface of the foil yarn.
図中９は増巾器、１０は確認機構を示す。この実施態様
では発光器２と受光素子４を箔糸１の下側に設けている
が、箔糸１の上側に設けてもよく、また発光器２と受光
素子４の配置関係を反対に、すなわち受光素子４を箔糸
面に対して斜方向の位置に、発光器２を箔糸面に対して
直下位置に配置してもよい。In the figure, 9 indicates an amplifier, and 10 indicates a confirmation mechanism. In this embodiment, the light emitter 2 and the light receiving element 4 are provided below the foil thread 1, but they may be provided above the foil thread 1, or the arrangement of the light emitter 2 and the light receiving element 4 may be reversed. That is, the light-receiving element 4 may be placed at an oblique position with respect to the foil thread surface, and the light emitter 2 may be placed directly below the foil thread surface.
つぎに作用を第２図、第３図に基いて説明する。Next, the operation will be explained based on FIGS. 2 and 3.
Ａ 箔糸が不正常な状態に緯入れされている場合（第２
図）
箔糸１の表面５は色模様が付き、着色光沢面となってい
るので発光器２から投射した光３は表面５の光沢面に当
たり、大部分が整反射光６となり、残りは色に吸収され
受光素子４には殆んど入らない。A: When the foil yarn is inserted in an abnormal state (second
Figure) The surface 5 of the foil thread 1 has a colored pattern and is a colored glossy surface, so the light 3 projected from the light emitter 2 hits the glossy surface of the surface 5, and most of it becomes regular reflected light 6, and the rest is colored. The light is absorbed by the light receiving element 4 and hardly enters the light receiving element 4.
Ｂ 箔糸が正常状態に緯入されている場合（第３図）
箔糸１の裏面Ｉは白い面であり、発光器２からの投射光
３がその箔糸１の白い無光沢の裏面７に当たれば、その
光は乱反射光８となって反射して受光素子４に入る。B When the foil yarn is inserted into the weft in a normal state (Fig. 3) The back side I of the foil yarn 1 is a white surface, and the projected light 3 from the light emitter 2 is directed to the white matte back side 7 of the foil yarn 1. When the light hits the light receiving element 4, the light becomes diffusely reflected light 8, is reflected, and enters the light receiving element 4.
このようにして、緯入れ装置により織目に通された箔糸
１が正常な状態であるか、不正常な状態であるかにより
受光素子４に入る光量に差が生じ、この光量の差を以っ
て箔糸１の表裏が検知されるのである。In this way, there is a difference in the amount of light entering the light receiving element 4 depending on whether the foil thread 1 passed through the weave by the weft insertion device is in a normal or abnormal state, and this difference in light amount is Thus, the front and back sides of the foil thread 1 can be detected.
その検知手段は受光素子４に連絡する増巾器９を介して
確認機構１０の表示燈或いはリレー、ソレノイドを用い
て正常な場合は織機を運転させ、不正常な場合は織機を
運転させない等によっている。The detection means uses an indicator light, a relay, or a solenoid of the confirmation mechanism 10 via a magnifier 9 that communicates with the light receiving element 4.If the condition is normal, the loom is operated, and if the condition is abnormal, the loom is not operated. There is.

に判別でき、箔糸が不正常な状態であるか、箔糸が正常
な状態であるかが明確に区別されるのである。As mentioned above, in this invention, the reflected light from the front and back sides of the foil thread,
Changes in the amount of reflected light are detected by determining the difference in the amount of reflected light received by the light-receiving element, which is constructed by arranging the light emitter and the light-receiving element in an oblique direction and a direction perpendicular to the plane of the foil yarn. Even if the foil thread is passed through the weave at an angle, the amount of diffusely reflected light from the back surface of the foil thread, which is received by the light receiving element, will not change significantly. It is clear that this is the case when the foil thread is in a normal state, so the difference in light intensity can be clearly distinguished, and it is clear whether the foil thread is in an abnormal state or in a normal state. They are distinguished.
従って織目に通された箔糸の状態如何にかかわらず箔糸
の表裏を常に正確に検知し、確認することができる。Therefore, regardless of the condition of the foil thread threaded through the weave, the front and back sides of the foil thread can always be accurately detected and confirmed.
そして装置が簡単である。And the device is simple.
