Title: Method and device for inspecting amount of articles
Inventor: INOUE HARUKI
IPC: G06M7/04
Filed: 1993-03-29
Abstract: PURPOSE:To easily inspect the kind and amount of articles with high precision at high speed. CONSTITUTION:Article color information composed of the feature color and area of an article surface for each kind of an article is previously registered by an article color information learning and registering means 8. When the kind of the article as the object of inspection and the number of staffs are applied from an inspection information generating means 9, an inspection reference color information generating means 3 calculates a reference color area by multiplying the number of staffs to the area for each registered feature color of the objective article. An image color information classifying means 4 integrates an actual color area in the same color as the registered feature color by analyzing a color for each unit area of an image photographing the plural objective articles. An inspectional judging means 5 judges the degree of coincidence between the integral value of actual color areas and the reference color area and decides whether the amount for each kind of articles exist as many as the scheduled number of staffs or not. Therefore, since the feature of articles is grasped corresponding to the color and the area, the amount of articles can be inspected with high precision at high speed by the device simplified in comparison with a method utilizing pattern matching.

Abstract: PURPOSE:To facilitate unbalance adjustment of a rotary body so as to reduce its processing manhours by forming connection between the disc of a rotary shaft and a moving blade in ruggedness fitting and arranging a stop blade on one part in a peripheral direction and also forming a shroud positioned in a specific direction from the arranged position of the stop blade lighter than the other shrouds. CONSTITUTION:Each moving blade 1 and each moving blade 2 to be a stop blade (or stop metal 3) are fixed on a rotary disc 5 by stop keys 4. Certain numbers of the moving blades 1 and the moving blades 2 to be the stop blades are combined together entire periiphery and connected to each other across its by the shroud 6. In this case, the material of the shroud 7 positioned in 180 deg. direction of the moving blade 2 to be the stop blade (stop metal 3) is made lighter than those of the other shrouds 6 by making it of, for example, titanium alloy. Thus, its unbalance is reduced and its weight is adjusted by changing the weight of a shroud 7.
