Embodiment 8.
FIG. 15 is a side sectional view showing the configuration of the identification apparatus according to Embodiment 8 of the present invention. The identification device according to the eighth embodiment shown in FIG. 15 includes a transport unit 110, a height adjustment unit 120, and an identification unit 130, and identifies the type and component of the identified object 101.

  Next, a series of operations of the identification device according to the eighth embodiment will be described. The transport unit 110 transports the supplied identified object 101 in the transport direction D <b> 1 and sequentially transports it to the height adjusting unit 120 and the identifying unit 130.

  The height adjusting unit 120 is a mechanism unit that adjusts the surface of the identification area of the identification object 101 that has been conveyed to a predetermined height H1. As shown in FIG. 15, the height adjusting unit 120 lowers the tip of the tip to a predetermined height H1 so that the surface of the identification area of the identification target object 101 conveyed to the identification unit 130 is changed to a predetermined level. The height is mechanically adjusted to H1. Then, the identifying unit 130 identifies the type and component of the identified object 101.

Next, features of the transport unit 110 will be described.
The transport unit 110 is made of a material having flexibility and a function of maintaining a predetermined time shape. This material includes, for example, a low-resilience material (foam) and a sheet containing a powdery, granular, fibrous, or gel-like substance, and more specifically, a low-resilience urethane foam or glass beads. Bag-like sheet.

  The surface of the identification area of the identified object 101 supplied to the conveyance unit 110 is pressed by the height adjustment means 120 at a predetermined point H1 that is the optimum height for identification. At this time, since the transport unit 110 is made of a material having flexibility and a function of maintaining a shape for a predetermined time, the pressed identification target object 101 maintains the height H1 when pressed. Then, it is conveyed to the identification means 130.

  The identified object 101 pressed in this manner reaches a position facing the identification unit 130 after a predetermined time has elapsed. The identification unit 130 includes a light irradiation unit 131 and a detection unit 132. And the light irradiation part 131 irradiates the identification area | region of the to-be-identified object 101 by which the height was adjusted to H1 by being irradiated with the irradiation light 131a. Next, the detection part 132 detects the reflected light or the scattered light 131b in the identification area | region by the irradiation light 131a.

  Here, the identification means 130 is a means for identifying the material of the identified object 101 based on the spectrum of the reflected light or scattered light 131b from the identified object 101. Raman, near infrared, mid-infrared, far infrared, visible light Known methods based on spectroscopic analysis such as UV, UV, and fluorescence can be used. For example, a technique based on Raman spectrum analysis is described in JP-A-10-38807, and a technique based on mid-infrared spectroscopy is described in JP-A-2001-108527.

  As described above, according to the eighth embodiment, even if the object to be identified has unevenness or warp, and the shape is different, the surface of the identification region is pinpointed to the optimum height for identification, With this height maintained, the object to be identified can be transported to a position facing the identifying means. For this reason, it is possible to identify the type and component of the identified object with high accuracy. Furthermore, since no window material or the like is provided between the transport unit and the identification means, it is possible to identify with high sensitivity and to transport the object to be identified without clogging between the transport unit and the window material.

  Furthermore, the material used for the transport unit is made of a material having flexibility and a function of maintaining a predetermined time shape. Therefore, for example, in the case of the structure of the endless conveyor as shown in FIG. 15, when a predetermined time has passed and the object to be identified on the transport unit moves downstream from the identification means, the height adjustment means is caused by its own weight. There is no dent on the surface of the conveying section caused by the pressure of

  As a result, when the next object to be identified is supplied onto the conveyance unit, the surface of the conveyance unit is returned to the original state, and can be continuously used, and the type and component of the object to be identified are always highly accurate. Can be identified.
