<p><P>PROBLEM TO BE SOLVED: To provide a ball supply device which, in spite of simple equipment, reduces a burden and handling time of an operator and which can easily supply balls to a working machine. <P>SOLUTION: The ball supply device 1 includes: a ball storage part 5 for storing balls 2; a ball supply part 7 which supplies balls 2 from a supply port 6 installed under the ball storage part 5 to the working machine 4 by using gravity acting on the balls 2; and a ball replenishment part 8 for replenishing the balls 2 to the ball storage part 5. The ball replenishment part 8 has a ball injection port 13 through which the balls 2 can be injected into the inside space 12, and is configured to be movable between a closable position 14 that can close the upper part of the ball storage part 5 and an injectable position 15 that is lower than the closable position 14. Also, in the bottom of the ball replenishment part 8, there is formed a communication port 18 that can switch from a communicative state to a noncommunicative state and vice versa, between the internal space 12 of the ball replenishment part 8 and the ball storage part 5, with the ball replenishment part 8 arranged in the closeable position 14. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
