Abstract

PURPOSE:To attain to enhance the quality of a product by accurately classifying whether the product is good or bad, by measuring up-and-down positions at four inspection points by a potentiometer and inspecting the height position of a specific point with respect to three inspection points coming to reference ones. CONSTITUTION:Guide rollers 7 each equipped with a roll 6 for receiving and supporting both side parts of the back surface of a product W are introduced and arranged from the outside at an inspection position 5 and side rollers 9 equipped with rolls 8 at the positions opposed to both side end surfaces of the product W are respectively arranged at the position 5 and the stopper for prescribing the position of the product W is further arranged to the end part of the position 5. When the product W is fed to the position 5, said product W is positionally prescribed by the rollers 7, 9 and the stopper and touch rollers 11 are upwardly pressed to the product W at four inspection points on the upper surface of said product W. This upward transfer quantity is converted to an electric signal by a potentiometer 14 to be inputted to an operation part 17 where the state to the reference value of a specific inspection point is operated when three reference inspection points are set to the same plain. The quality of the product W is classified to be displayed on a display device 18.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for inspecting the distortion of tile products, which measures the degree of distortion of tile products to classify good products and defective products.

Generally, tile products are distorted after drying and firing due to non-uniformity of raw material density during the molding stage, but conventionally, such distortion inspection was done visually by the P-milling worker, so it is now possible to standardize the classification of good and defective products. The specified type could not be executed.

In view of these drawbacks, the present invention has been developed by holding a tile product to be inspected at a predetermined inspection position, setting four inspection points on a predetermined part of the surface of the tile product, and using a potentiometer placed opposite each inspection point. The vertical position of each inspection point is measured using a meter, and the type of tile product is inspected for non-defective products, defective punch lines, and defective springs based on the height position of one specific inspection point relative to the three standard inspection points. An embodiment of the present invention will be described below with reference to the drawings, with the aim of solving the above-mentioned drawbacks by providing a strain testing method and device.1 is the main body of the strain testing device for tile products W; A window 4 is opened in the center of the box 3, which is equipped with casters 2.2a, and an inspection position 5 is provided inside. A guide roller 7.7a equipped with rollers 6.6a for receiving both sides of the back surface of the product W is introduced from the outside, and the tile product W is supported by the guide roller 7.7a at the inspection position 5. Side rollers 9.9a equipped with rollers 8.8a, . 10a is arranged.

In addition, a total of four inspection points A, B, C, and D are set at both ends of the insertion side and the machine side of the surface of the tile product W to be carried into the inspection position 5, and each inspection point A ,B,C,D
A touch roller 11, Ila...
The touch roller 1 is arranged rotatably, and the touch roller 1

．． The potentiometers 14, 14a, . The state of each inspection point A, B, C, and D is electrically grasped by electrical signals at the upper and lower positions, and the state is displayed on the display section 18.

Note that 19 is a confirmation sensor that confirms that the tile product W has been brought into the inspection position 5.

Next, to explain the strain testing method for tile products according to the present invention, first, a model tile serving as a reference for testing is carried through the guide roller 7.7a to the testing position 5, and in this state, the potentiometer 14.14a- detects the distortion. In the displacement amount of inspection points A, B, and C1D, three inspection points B,
The vertical position of inspection point A when the CXD is on the same plane is taken as a reference value, and if inspection point A is lower or lower than this reference value by the specified amount, it is a punch line defect, and if it is above this value, it is a spring defect.
If it falls within a predetermined range, it is classified as a good product.

During the inspection, the tile product W to be inspected is placed on the guide roller 7.7a, the head end is stopped, and the bar 10.
10a, the tile product W is positioned at the inspection position 5 by the guide roller 7.7a, side roller 9.9a, and stopper 10, and as the tile product W is brought in, the touch roller 11, lla...
is pressed upward by the inspection points A, B, C, and D on the upper surface of the tile product W, and the amount of upward displacement is further reduced by the support rods 12.12a and 12.12a.

The amount of displacement is transmitted to the operating rods 15.15a..., and the displacement amount is converted into an electric signal by the potentiometers 14.14a... and introduced to the computing unit 17, where the inspection points BSC, D are detected. The state of the inspection point A with respect to the reference value when the inspection point A is on the same plane is calculated, and based on this, the types of good products, punch defects, and spring defects are displayed on the display section 18.

In short, the present invention holds a tile product W to be inspected at a predetermined inspection position 5, sets four inspection points A, B, C, and D on a predetermined portion of the surface of the tile product W, and each inspection point A ,
Potentiometer 1 placed opposite B, C, and D
4.14a... Measure the vertical position of each inspection point A, B, C, D, and determine the height position of one specific inspection point A with respect to the three reference inspection points B, C, D. Since the type inspection is conducted for good products, defective punch lines, and defective springs, the tile products W to be inspected can be inspected by simply transporting them into the inspection position 5.
It is possible to convert the degree of distortion into an electrical signal and display it electrically by detecting the degree of distortion with the potentiometer (4.14a). Therefore, it is possible to easily and accurately classify tile products W into good products, defective punch lines, and defective springs. Therefore, it is possible to improve the quality of the tile products W to be shipped, and
By classifying the tile products W with defective punch lines and defective springs, the practical effects are enormous, such as the ability to collect products with defective punch lines and defective springs required for specific roof shapes.
