The present invention relates to a robot cleaner for a billiard table. More specifically, the present invention relates to a robot cleaner for a billiard table that moves freely along the top of the billiard table and tap on the table so as to allow dust and chalk powder on the table cloth to float, and then removes floating dust and chalk powder by sucking the same. Accordingly, the robot cleaner for a billiard table of the present invention can extend the service life of a table cloth by preventing the woven structure from being damaged by friction as well as by preventing dust and chalk powder from being embedded in the table cloth.

Description

Robot cleaner for billiard table {ROBOT CLEANER FOR BILLIARD TABLE}

The present invention relates to a robot cleaner for a billiard table, and more particularly, while moving freely along the upper plate of the billiard table, lightly hitting the upper plate to lift the dust and chalk powder from the cloth, and then sucking the suspended dust and chalk powder It relates to a robot cleaner for a billiard table that can extend the life of the fabric by preventing the tissue from being damaged by friction while preventing dust or chalk powder from sticking by removing it.

In general, a billiard table puts marble on the bottom surface recessed to a certain depth and size from the upper end of a table having a predetermined height and size, and the upper surface of the marble is coated with a cloth called screw paper (羅紗紙) and adhered. And, along the outer periphery (perimeter) of the upper surface of the marble, a cushion portion made of a urethane rubber material is formed.

The fabric of the billiard table is vulnerable to dust and easily accumulates dust. In particular, there are cases where foreign substances such as chalk powder and chalk fragments are attached or liquid such as coffee is sometimes spilled during a billiard game. If these microscopic foreign substances are present on the fabric of the billiard table, the billiard ball does not roll properly and has a significant effect on the game, so cleaning is necessary.

The cleaning of the billiard table is generally done by using a cleaning cloth, and the billiard room operator directly manually rubs the top and cushion parts of the billiard table several times to steal chalk powder and chalk pieces, and then use a vacuum cleaner to suck in foreign substances.

However, this cleaning method has a problem in that a portion of the chalk powder is embedded in the cloth in the process of rubbing and stealing the cloth, and the wool of the cloth is swept away due to friction caused by repeated cleaning, thereby damaging the tissue. This shortened the life of the cloth, which caused the replacement cycle of the cloth to become faster, and in the end there was a problem in that it puts an economic burden on the operator of the billiard room.
