Problems solved by technology

Moreover, when the spoilage fungus attaches to other citrus, it is possible to rot other normal citrus
[0004] The new lesions (including wet rot) have almost the same color as the skin of normal fruits, so unlike ordinary lesions, it is difficult to distinguish them by visual inspection by inspectors or by ordinary devices for inspecting lesions using visible light.

Embodiment approach 1

[0043] figure 1 It is a schematic plan view of the agricultural product inspection device 1 according to the first embodiment of the present invention. The agricultural product inspection device 1 of the present embodiment includes a conveyance unit 2, a plurality of imaging units 3 (3a to 3e in the drawings are collectively referred to as "3". Hereinafter, the same applies to other branch marks), and a plurality of visible light irradiation units. 4. A plurality of ultraviolet irradiation units 5 and a control unit 6 . In this embodiment, the imaging units 3a and 3b are arranged to image the agricultural product 10 from the upstream side, the imaging units 3c and 3d are arranged to image the agricultural product 10 from the downstream side, and the imaging unit 3e is arranged to image the agricultural product 10 from above. In order to avoid the influence of external light, the agricultural product inspection device 1 is preferably installed in a dark room covered with a shi...

Abstract

The invention provides a farm produce inspection apparatus that can perform normal appearance inspection by visible light irradiation and new wounds and wet-rot inspection by ultraviolet irradiation. The farm produce inspection apparatus comprises a transmit unit that transmits farm produce; a shooting unit that shoots the farm produce transmitted by the transmit nit; a visible light irradiation unit that irradiates visible light to the farm produce; a ultraviolet irradiation unit that irradiates the farm produce; and a control unit that controls the shooting unit, the visible light irradiation unit and the ultraviolet irradiation unit, wherein the control unit controls either the visible light irradiation unit or the ultraviolet irradiation unit irradiates at every preset time, and controls the same shooting unit shoots the farm produce based on a first shooting condition when the visible light irradiation unit irradiates and a second shooting condition when the ultraviolet irradiation unit irradiates.

Description

technical field [0001] The present invention relates to techniques for inspecting agricultural products, and more particularly to an agricultural product inspection device and method for inspecting agricultural products by irradiating visible light to inspect the appearance of agricultural products and detecting fluorescent reactions from new wounds formed on the epidermis by irradiating ultraviolet rays. Background technique [0002] In the past, in order to check the usual damage (including scars generated before harvest, insects, discoloration, dirt, mold after rot), size, shape, etc. of agricultural products, the method of imaging and inspecting agricultural products with an appropriate imaging unit has been used. Appearance inspection device. [0003] However, among agricultural products, there are spherical oil glands with a diameter of about 1 mm on the epidermis of citrus such as oranges, grapefruits, and grapefruits, which contain essential oils such as limonene. W...
