ところで、本願出願人が上記従来の布類検査装置についてさらに研究を進めたところ、上記従来の布類検査装置では、布類の両面を検査できるようになったものの、布類の内部の汚れや破れ等の異常の他、布類と同系色の表面の汚れ等の異常の検出が充分にはできないということが判明した。そしてこの問題の解決のためには、布類を透明な台上に通して透過光で検査をすることも考えられるが、その方法では、透明な台の汚れや傷つき等によって検査能力が低下し易いという問題があった。それゆえ近年は、さらに高い検査能力の布類検査装置の開発が望まれていた。   By the way, when the applicant of the present application further researched on the conventional cloth inspection apparatus, the conventional cloth inspection apparatus can inspect both sides of the cloth, In addition to abnormalities such as tearing, it has been found that abnormalities such as dirt on the surface of the same color as the cloth cannot be detected sufficiently. In order to solve this problem, it is conceivable that the cloth is passed through a transparent table and inspected with transmitted light. However, this method deteriorates the inspection capability due to dirt or scratches on the transparent table. There was a problem that it was easy. Therefore, in recent years, it has been desired to develop a cloth inspection apparatus having a higher inspection ability.

At least the light transmitted from the light source to the expanded cloth jumping through the gap between the delivery conveyor and the receiving conveyor and transmitted through the cloth, and at least the light reflected from the cloth A camera that shoots the cloth with light transmitted through the cloth and outputs an image;
It is characterized by comprising.

かかる本発明の布類検査装置にあっては、ジャンプ手段が、何れも拡げられた布類を搬送する送り出しコンベヤから受け取りコンベヤへ、拡げられた布類をジャンプさせ、前記送り出しコンベヤと前記受け取りコンベヤとの間の隙間をジャンプしている拡げられた布類に光源から照射されてその布類を透過した光と、その布類から反射した光とのうち、少なくともその布類を透過した光によって前記布類をカメラが撮影して画像を出力する。   In the cloth inspection apparatus according to the present invention, the jump means causes the spread cloth to jump from the delivery conveyor that conveys the spread cloth to the reception conveyor, and the feeding conveyor and the receiving conveyor. The light that has been spread from the light source to the spread cloth that is jumping through the gap between the light and the light that has passed through the cloth and the light that has been reflected from the cloth has been transmitted by at least the light that has passed through the cloth. The cloth is photographed by a camera and an image is output.

従って、この発明の布類検査装置によれば、送り出しコンベヤと受け取りコンベヤとの間の隙間をジャンプ手段によってジャンプしている拡げられた布類に光源から照射されてその布類を透過した光と、その布類から反射した光とのうち、少なくともその布類を透過した光によってその布類を撮影したカメラが出力する画像に基づき、拡げられた布類を検査することができるので、高い検査能力で、布類の内部の汚れや破れ等の異常の他、布類と同系色の表面の汚れ等の異常の検出も充分におこなうことができ、しかも、布類を透明な台上に通して透過光で検査を行うのではないから、透明な台の汚れや傷つき等によって検査能力が低下するということもないので、その高い検査能力を長期間維持することができる。   Therefore, according to the cloth inspection apparatus of the present invention, the spread cloth jumping by the jump means in the gap between the sending conveyor and the receiving conveyor is irradiated from the light source and transmitted through the cloth. Because the cloth spread can be inspected based on the image output from the camera that has photographed the cloth with the light reflected from the cloth at least through the light transmitted through the cloth. Ability to detect abnormalities such as stains and tears inside the fabric as well as abnormalities such as stains on the surface of the same color as the fabric, and passing the fabric on a transparent table Since the inspection is not performed with transmitted light, the inspection ability is not deteriorated due to dirt or scratches on the transparent table, and the high inspection ability can be maintained for a long time.

なお、この発明の布類検査装置においては、前記拡げられた布類に光源から照射されてその布類の表面から反射した光によって前記布類を撮影して画像を出力する、さらなるカメラを具えていると、透過光では透過してしまうような透明に近い表面の汚れ等でも、そのさらなるカメラが出力する画像に基づいて検出できることから、さらに高い検査能力を発揮することができるので好ましい。   The cloth inspection apparatus according to the present invention further includes a camera that shoots the cloth with light reflected from the surface of the cloth and outputs an image by irradiating the spread cloth with a light source. It is preferable that even near-transparent dirt that is transmitted by transmitted light can be detected on the basis of the image output from the further camera, so that a higher inspection capability can be exhibited.

Since the video camera 19 is further provided to output an image, even in the case of the cloth F which has been expanded, even on the lower and upper surfaces, even near transparent dirt which is transmitted by transmitted light, etc. Since it can be detected by a normal image processing device or the like based on the images output from the two video cameras 13 and 19, respectively, higher inspection capability can be exhibited.

さらに、この実施例の布類検査装置3によれば、ジャンプ手段が、送り出しコンベヤ5の送り出し側端部に、受け取りコンベヤ6の受け取り側端部へ向けて設けられ、拡げられた布類Fを下から支持して、先端からその拡げられた布類Fをジャンプさせるジャンプ台7を有していることから、拡げられた布類Fを簡易且つ安価な構成でジャンプさせることができる。   Furthermore, according to the cloth inspection apparatus 3 of this embodiment, the jump means is provided at the sending side end portion of the sending conveyor 5 toward the receiving side end portion of the receiving conveyor 6, and the spread cloth F is provided. Since it has the jump stand 7 which supports from the bottom and jumps the expanded fabric F from the tip, the expanded fabric F can be jumped with a simple and inexpensive configuration.

なお、図5の左側に示すように、ジャンプ台7がない場合には、図5の右側に示すように、アイロンローラ1での仕上げ工程で静電気を帯びているシーツや、湿っているため柔らかくて重いシーツ等の布類Fは、送り出しコンベヤ5の先端部でコンベヤベルトから剥離せずに下側に巻き込まれてしまい、また、紐状になったもしくは紐状のものが付属しているシーツ等の布類Fは、送り出しコンベヤ5の先端部にその紐状の部分が引っ掛かってしまい、何れも、送り出しコンベヤ5の送り速度が遅い場合には受け取りコンベヤ6までジャンプできない場合がある。   As shown on the left side of FIG. 5, when there is no jumping base 7, as shown on the right side of FIG. The cloth F, such as a heavy sheet, is wound down on the lower end of the delivery conveyor 5 without being peeled off from the conveyor belt, and the sheet F or the sheet attached with the string is attached. In the case of the fabric F, the string-like portion is caught at the tip of the delivery conveyor 5, and in any case, when the feeding speed of the delivery conveyor 5 is low, the reception conveyor 6 may not be jumped.

一方、図6に示すように、受け台8がない場合でも、ジャンプ台7の先端が受け取りコンベヤ6の受け取り側端部より充分高ければ、送り出しコンベヤ5の送り速度が遅くても上述した布類Fが受け取りコンベヤ6までジャンプできる可能性が高い。   On the other hand, as shown in FIG. 6, even when there is no cradle 8, if the tip of the jump pedestal 7 is sufficiently higher than the receiving side end of the receiving conveyor 6, the above-described fabrics can be used even if the feeding speed of the feeding conveyor 5 is slow. There is a high possibility that F can jump to the receiving conveyor 6.

さらに、この実施例の布類検査装置3によれば、ジャンプ手段が、受け取りコンベヤ6の受け取り側端部に、ジャンプ台7へ向けて設けられ、そのジャンプ台7からジャンプした拡げられた布類Fを受けて受け取りコンベヤ6に引き渡す受け台8を有していることから、受け取りコンベヤ6が拡げられた布類Fを落下させずにより確実に受け取って搬送することができる。   Furthermore, according to the cloth inspection apparatus 3 of this embodiment, the jumping means is provided at the receiving end of the receiving conveyor 6 toward the jumping base 7 and the expanded cloth jumping from the jumping base 7 is provided. Since it has the receiving stand 8 which receives F and delivers to the receiving conveyor 6, it can receive and convey more reliably the cloth F which the receiving conveyor 6 was expanded without dropping.

図7は、上記実施例の布類検査装置の一変形例の構成および機能を示す説明図であり、この変形例の布類検査装置3では、受け取りコンベヤ6の受け取り側端部が、図中矢印で示すように、送り出しコンベヤ5の送り出し側端部に対して接近および離間移動でき、これにより受け台8が、ジャンプ台7との間に水平方向の所定間隔を空ける、図4の右側に示す布類透過検査位置と、その布類透過検査位置よりもジャンプ台7に接近する、図7に示す布類落下防止位置との間で移動可能とされている。   FIG. 7 is an explanatory view showing the configuration and function of a modified example of the cloth inspection apparatus of the above embodiment. In the cloth inspection apparatus 3 of this modification, the receiving side end of the receiving conveyor 6 is shown in the figure. As shown by the arrows, it can move toward and away from the delivery side end of the delivery conveyor 5 so that the cradle 8 is spaced apart from the jump pedestal 7 in the horizontal direction on the right side of FIG. It is possible to move between the cloth penetration inspection position shown and the cloth fall prevention position shown in FIG. 7 closer to the jump stand 7 than the cloth transmission inspection position.

従って、この変形例の布類検査装置3によれば、油布等の、透過光による検査が不要で、且つ搬送速度が遅く、しかも柔らかい布類を搬送する場合に、送り出しコンベヤ5の送り速度が遅くてその布類Fがジャンプ台7から充分にジャンプできずにジャンプ台7と受け台8との隙間から落下してしまうのを防止することができる。   Therefore, according to the cloth inspection apparatus 3 of this modified example, when the cloth cloth is not required to be inspected by transmitted light, and the conveyance speed is slow and soft cloth is conveyed, the feeding speed of the delivery conveyor 5 is increased. It is possible to prevent the cloth F from falling from the gap between the jump base 7 and the cradle 8 without being able to sufficiently jump from the jump base 7 at a later time.

以上、図示例に基づき説明したが、この発明は上述の例に限定されるものでなく特許請求の範囲の記載範囲内で適宜変更し得るものであり、例えば上記実施例では送り出しコンベヤ5の上方に、拡げられた布類Fに反射光源17から照射されてその布類Fの表面から反射した光によってその布類を撮影して画像を出力する、さらなるビデオカメラ19を具えているが、これに代えて、あるいは加えて、受け取りコンベヤ6の上方に、同様のビデオカメラ19を具えても良い。 Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described examples and can be appropriately changed within the scope of the claims. For example, in the above embodiment, the upper side of the delivery conveyor 5 In addition, there is provided a further video camera 19 that shoots the cloth with light reflected from the surface of the cloth F by irradiating the spread cloth F from the reflection light source 17 and outputs an image. Alternatively or in addition, a similar video camera 19 may be provided above the receiving conveyor 6.

また、上記実施例ではビデオカメラ13が、隙間Gをジャンプしている拡げられた布類Fにその上方の透過光源10から照射されて布類Fを透過した光だけでなく、隙間Gをジャンプしている拡げられた布類Fに隙間Gの下方の反射光源11から照射されてその布類Fから反射した光によってもその布類Fを撮影しているが、これに代えて、透過光源10から照射されて布類Fを透過した光だけで布類Fを撮影するようにしても良く、さらに、透過光源10を隙間Gの下方に配置するとともにビデオカメラ13を隙間Gの上方に配置するようにしても良い。   Further, in the above-described embodiment, the video camera 13 jumps not only the light transmitted from the transmission light source 10 above the spread fabric F jumping through the gap G and transmitted through the fabric F, but also jumps through the gap G. The cloth F is also photographed by the light reflected from the cloth F that is irradiated from the reflected light source 11 below the gap G to the spread cloth F that is spread. The cloth F may be photographed only with the light irradiated from 10 and transmitted through the cloth F, and the transmission light source 10 is arranged below the gap G and the video camera 13 is arranged above the gap G. You may make it do.

そして、上記実施例では送り出しコンベヤ5受け取りコンベヤ6との2台のベルトコンベヤを具えているが、本発明の布類検査装置はこれに限られず、さらに多くのコンベヤを具えていても良く、あるいは1台のベルトコンベヤの2箇所を送り出しコンベヤ5および受け取りコンベヤ6として構成しても良い。また、本発明の布類検査装置におけるジャンプ手段は、ジャンプ台を上記実施例における形状や構成のジャンプ台7から所要に応じて適宜変更しても良く、受け台8を省略することもできる。 And in the said Example, although the two belt conveyors of the sending conveyor 5 and the receiving conveyor 6 are provided, the cloth inspection apparatus of this invention is not restricted to this, You may provide more conveyors, Alternatively, two portions of one belt conveyor may be configured as the delivery conveyor 5 and the reception conveyor 6. Also, jump means in cloth inspection apparatus of the present invention may be changed as appropriate according to required to jump from the jump 7 shapes and configurations in the above embodiment, it is also possible to omit the cradle 8.

かくしてこの発明の布類検査装置によれば、送り出しコンベヤと受け取りコンベヤとの間の隙間をジャンプ手段によってジャンプしている拡げられた布類に光源から照射されてその布類を透過した光と、その布類から反射した光とのうち、少なくともその布類を透過した光によってその布類を撮影したカメラが出力する画像に基づき、拡げられた布類を検査することができるので、高い検査能力で、布類の内部の汚れや破れ等の異常の他、布類と同系色の表面の汚れ等の異常の検出も充分におこなうことができ、しかも、布類を透明な台上に通して透過光で検査を行うのではないから、透明な台の汚れや傷つき等によって検査能力が低下するということもないので、その高い検査能力を長期間維持することができる。   Thus, according to the cloth inspection apparatus of the present invention, the light that has been irradiated from the light source to the spread cloth jumping by the jump means through the gap between the sending conveyor and the receiving conveyor and transmitted through the cloth, High inspection capability because the spread fabric can be inspected based on the image output by the camera that captured the fabric with at least the light reflected from the fabric and transmitted through the fabric In addition to abnormalities such as stains and tears inside the cloth, it is possible to detect abnormalities such as dirt on the surface of the same color as the cloth, and the cloth can be passed through a transparent table. Since the inspection is not performed with the transmitted light, the inspection ability is not deteriorated due to dirt or scratches on the transparent table, and the high inspection ability can be maintained for a long time.
