【考案の詳細な説明】 ［産業上の利用分野］ 本考案は、色彩選別装置の光学検出器に取付ける色彩選
別装置の照明ランプに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an illumination lamp of a color selection device attached to an optical detector of the color selection device.

を選別する物があった。[Prior Art] In a color selection device, the light of an incandescent lamp is condensed by a convex lens, and this light is further condensed by a second lens to irradiate a light spot in a circular shape as shown in FIG. However, there is an object that reflects the light radiated from the searched object detected in the spot and selects a foreign material having a brighter color (white, yellow, or orange) from the black color tones.

できない。[Problems to be solved by the invention] The detection of a bright color foreign matter from the black color tone is because the bright color has a larger amount of light reflection, and the black color can be detected even if it enters the spot at the same time. is there. However, when detecting a darker color tone of a bright object, if the light spot is circular, the area within the field of view of the sensor is large, so it cannot be detected when objects to be searched overlap or continue to come. . In addition, since an object that reflects more light than a search object enters the same field of view, the object to be detected is fooled by the object itself, and reliable and efficient detection cannot be performed.

のである。[Means for Solving Problems] In view of such circumstances, the present invention is an idea for addressing these problems, and a spherical lens having a short focal length in order to efficiently collect light emitted from a lamp. The light collected by this spherical lens is focused by a so-called cylindrical lens which is a second lens, and a slit for the diaphragm of the light is provided behind the spherical lens to extract only the linear light and the second lens is used. Converging light to obtain an accurate rod-shaped spot 1
It is intended to provide a lighting lamp which can reliably check each product and can be selected even if the flow rate is increased.
