Embodiment Construction

[0026] figure 1 is an external view showing the size and shape measuring device of the present invention, figure 2 It is a block diagram showing the size and shape measuring device. The measurement device 10 includes a measurement table 1 , a measurement head 2 and an arithmetic processing device 8 .

[0027] The measuring stand 1 includes a mounting surface 1a on which a cylindrical object T such as a tire is mounted, a height displacement measuring device 6, a lower stopper 1d, and a support 1c. The mounting surface 1a is located on the upper surface of the measuring table 1, and has a recessed portion 1i at the center thereof. A lower stopper 1d is provided in the retreat portion 1i. The pillar 1c extends in the vertical direction on the side of the measuring table 1, and includes a guide support 1g and a pulley support 1h. One end of the guide support 1g is fixed to the pillar 1c and a positioning guide 1b is fixed at the other end. The positioning guide 1b is formed i...

Abstract

A measuring apparatus for automatically measuring the height, the dimensions of the inner and outer surfaces, and the shape of a cylindrically-shaped object. The measuring apparatus includes a measuring head (2) vertically moving along a positioning guide (1b) supported by a support post (1c) integral with a measuring table (1), a height displacement measuring device (6), which comprises a laser distance meter (6a) provided on the measuring table (1), and an arithmetic processing unit. The measurement starts as the measuring head (2) is raised by a weight (5) from a measuring start position of the measuring table (1). The inner and outer surfaces of a tire (T) are measured based on the measurements by an inner surface measuring device (3) provided with three laser distance meters (3a, 3b, 3c) mounted to the measuring head (2) and an outer surface measuring device (4) having a laser distance meter (4a) and the displacement change measurement of the measuring head (2) by the height displacement measuring device (6). Required dimensional values are calculated from the measured values, using the arithmetic processing unit.

Description

technical field [0001] The present invention relates to measurement of the size and shape of a cylindrical object to be measured, for example, an apparatus and method for automatically measuring and calculating the size and shape of a tire. Background technique [0002] Conventionally, when measuring the size of a tire, the size of each part of the tire was manually measured using a scale, a triangle, a tape measure, or the like. In addition, as a means of measuring the size of the tire, there is a method proposed in Patent Document 1, that is, image processing is performed with a CCD camera, and a plurality of patterns stored in the recognition device in advance are compared with a predetermined pattern obtained by image processing to recognize Tires to measure the tire size. [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 7-39827 [0004] However, when measuring manually with a measuring device such as a scale, not only the reading error of the meas...
