Description

Baseball ball weight automatic sorter

The present invention is a device that automatically selects the weight of a baseball, and more particularly, by measuring the weight of a baseball that is inserted into the system, the transport path of a baseball that satisfies a preset reference value and a baseball that does not are different from each other, It relates to an automatic weighing machine for distinguishing defective products.

Baseball, which was re-adopted as an official sport at the 2020 Summer Olympics, will be played with the officially designated ball for each tournament or league. In general, baseballs are made by winding a thread around a small core made of cork, rubber, or similar material, and wrapping white horseskin or cowhide on both sides.

When making a baseball, the quality of the batted ball changes significantly depending on the circumference, coefficient of restitution, and weight of the ball. In other words, even if the pitcher throws the same pitch to the catcher according to the above-described multiple variables, while the batter hits the ground ball, a home run occurs.

In order to solve the above problem, the steering committee of each league limits the value of the baseball variable to a specific range. The KBO limits the range of values for the weight of a certified baseball to 143.5 grams (g) to 148 grams (g). In order to satisfy the above weight value, a company that manufactures a baseball performs a separate operation to check the weight of the baseball.

Conventionally, after the baseballs are individually separated, a separate manager for measuring the weight is arranged to place the baseball on a weight measuring scale. In the above-described operation, a separate manpower manually performs the step of placing the baseball ball on the scale, checking the weight of the baseball ball displayed on the scale, and taking the baseball ball out of the scale. Therefore, the overall efficiency of classifying a baseball according to its weight is inevitably lowered.

In addition, conventionally, in the process of measuring the weight of a baseball, a scale configured to measure the weight was used. Accordingly, the position of the spherical baseball ball is not fixed, causing a problem in that the range of the error value for the measured weight may increase.

The technology related to the automatic weighing device is also described in Korean Utility Model Publication No. 20-0464257. The above document is a device that automatically sorts the weight of food sealed in a stick form, and classifies good and defective products according to the measured weight. However, it does not describe a configuration capable of efficiently measuring a product having a spherical shape.
