Description

TECHNICAL FIELD

[0001] The utility model relates to a vibrating disc technical field, in particular to a vibrating disc with proximity sensor. BACKGROUND

[0002] The existing vibrating disc when conveying inductance type material with metal tin foot, usually adopts a group of reflection type optical fiber to carry out material front and back surface identification, thereby completing material selection, this material selection mode is that the light source emission end in the optical fiber amplifier passes through the optical fiber line and the lens connected at the port and shines the light on the surface of the material to be distinguished, the emitted light is reflected by the surface of the material back to the lens and finally returns to the optical fiber amplifier, because the reflection degree of the front and back surface of the material will exist difference, so the light source intensity displayed on the amplifier will also have difference, and the difference is used to distinguish the front and back surface effect of the material.

[0003] Because this material selection mode selects material through the light emitted by the amplifier, but now the material due to the difference of production process and surface spraying color treatment, the reflection value of the surface of the same batch of material is also different, in addition, due to the material quality and the use environment of the scene will have some dust, these factors are easy to cause the light emitted by the optical fiber and the light source reflected back to be affected, thereby causing the screening of the front and back surface of the material to exist misjudgment.
