Description

  The present invention relates to a ball take-out device for taking out game balls randomly put into a hopper one by one and sending them to a washing machine or the like.

  In recent years, amusement facilities using soft play balls have been installed in commercial facilities and amusement parks. However, since the play balls used in such play facilities touch the hands of many people, It is necessary to keep it clean. For this reason, there has been proposed a washing machine that automatically cleans the game balls with a brush while continuously moving the collected game balls.

  For automatic operation of such a washing machine, it is necessary to have a ball take-out device that can take out a large number of play balls randomly placed into the hopper one by one at regular intervals and supply them to the washing machine. Become.

  As shown in FIG. 15, the basic structure of a conventionally used ball take-out device is a horizontal rotation driven by a motor 2 at the bottom of a hopper 1 that accommodates a large number of randomly inserted play balls A. A plate 3 is arranged, and a plurality of ball storage cylinders 4 into which a single play ball A in the hopper 1 falls are provided on the same rotation center of the rotation plate 3. A bottom plate 5 that supports and holds the game ball A that has fallen into the ball storage cylinder 4 is fixedly disposed at a lower position of the rotating plate 3, and is rotated to one position of the bottom plate 5. A ball take-out port 6 is provided for discharging the game balls A in the ball storage tube 4 each time the ball storage tube 4 faces directly above.

  When the rotating plate 3 is rotated by the motor 2 in a state where a large number of playing balls A are randomly inserted into the hopper 1, the playing ball A that has fallen into the ball storage cylinder 4 of the rotating plate 3 is When the ball storage cylinder 4 faces the ball take-out port 6 while being supported by the rotary plate 3, the game ball A in the ball storage cylinder 4 is taken out. The play balls A are intermittently taken out one by one at intervals defined by the interval in the ball storage cylinder 4 and the rotation speed of the rotating plate 3, and this is supplied to, for example, a subsequent washing machine.

  In the ball take-out device as described above, a ball is placed above the rotating plate 3 in the tank 1 and above the ball take-out port 6 so that the play balls A can be taken out one by one intermittently. A cover plate 7 is provided to cover the top of the phased ball storage cylinder 4 located immediately above the takeout port 6, and the game ball A is placed on the phased ball storage cylinder 4 located directly above the ball takeout port 6 with the cover plate 7. Is not directly dropped, and when the ball moves over the play ball A that has fallen into each ball storage cylinder 4 and moves directly above the ball outlet, the upper game ball A is covered. A plate 7 is used to eliminate the upper part.

  By the way, as described above, when the upper part of the phased ball storage cylinder 4 positioned immediately above the ball outlet 6 is covered with the cover plate 7, as shown in FIGS. 16 and 17, the empty ball storage cylinder 4 is rotated. In some cases, a state in which the game ball A is sandwiched between the upper end opening edge of the cover plate and the entrance side end edge of the cover plate 7 may occur.

  Thus, when the game ball A is sandwiched between the upper end opening edge of the ball storage cylinder 4 and the entrance side end edge of the cover plate 7, the rotation of the rotary plate 3 is stopped, and the game ball A is taken out. The problem that it becomes impossible to occur.

  Further, when a large number of game balls A are inserted into the tank 1, a bridge phenomenon may occur in which the game balls A are stuck against each other in the hopper and the take-out of the game balls A may be interrupted. .

  Thus, the object of the present invention is to eliminate the occurrence of pinching of the play balls between the upper end opening edge of the ball storage cylinder and the entrance side end edge of the cover plate, and the play balls can be taken out continuously. Another object of the present invention is to provide a ball take-out device that can eliminate the occurrence of the bridging phenomenon of play balls.

  In order to solve the problems as described above, the present invention has a horizontal rotating plate arranged at the bottom of a hopper capable of storing a large number of balls, and a ball storage cylinder into which one ball in the hopper falls, A plurality of base plates are provided on the same circumference centering on the rotation axis of the rotating plate, and a bottom plate for supporting the ball that has fallen into the ball storage tube and holding it in the ball storage tube is fixedly arranged at a lower position of the rotating plate. In addition, a ball take-out port for discharging the ball in the ball storage cylinder every time the rotating ball storage cylinder faces directly above is provided at one position of the bottom plate, and the ball take-out port of the bottom plate at the upper part of the rotary plate inside the hopper A cover plate that covers the upper portion of the ball storage cylinder is disposed at a position above the ball so that the ball does not fall directly into the phase of the ball storage cylinder located directly above the ball outlet. The portion of the Le entry side, when sandwiched ball between the ball receiving cylinder which rotates, is obtained by employing the configuration in which the movable cover to release the ball to open upwardly by being pushed by the ball.

  The cover plate is fixed to the inner surface of the hopper, and a cover plate main body having a notch at a tip portion facing directly above the ball storage cylinder having a phase located immediately above the ball outlet, and a cover for opening and closing the notch A structure can be formed which includes a movable lid attached to the plate body so as to be movable up and down, and an elastic member which urges elasticity so as to always close the notch to the movable lid.

The vertical axis may be inserted into the cam cylinder, and the horizontal axis may be supported by an inclined surface and installed in the hopper.

  Here, the rotating plate is a rectangular bottom of the hopper, and is horizontally disposed at a position offset from one corner, and the bottom of the hopper is inclined downward toward the rotating plate, and the ball toward the rotating plate. Roll to gather.

  When the cover plate moves to a position directly above the ball outlet in a state where the ball overlaps the ball that has fallen into each ball storage cylinder with respect to the rotating plate, the upper ball rides on this, It is fixedly arranged at such a height that it can be removed upward so that two balls are not taken out continuously.

  According to the present invention, the cover plate that covers the upper portion of the ball storage cylinder is disposed so that the ball does not fall directly into the phase of the ball storage cylinder positioned directly above the ball outlet, and the portion of the cover plate on the ball entry side is arranged. When the ball is sandwiched between the rotating ball storage cylinder, the ball is pressed by the ball to open upward and release the ball, so the upper edge of the ball storage cylinder and the cover plate are inserted. When the ball is sandwiched between the side edges, the movable lid pressed by the ball opens upward and escapes to free the ball, and the ball is sandwiched between the upper edge of the ball storage cylinder and the cover plate. By preventing the occurrence and preventing the rotating plate from stopping, the balls can be taken out accurately at regular intervals.

  Also, by inserting the vertical axis of the ball clogging prevention device into the cam cylinder of the rotating plate and installing it in the hopper with the horizontal axis supported by the inclined surface, the ball bridge preventing device is utilized by utilizing the rotation of the rotating plate. By swinging up and down in the hopper and moving the balls thrown into the hopper, it is possible to eliminate the occurrence of a bridging phenomenon that prevents the balls from sticking to each other and moving in the hopper, and the entire amount of balls in the hopper can be taken out. .

  The ball storage cylinder 14 has a cylindrical shape with an inner diameter that can accommodate a single play ball A, and has an upper end opened at the upper surface of the rotating plate 12, and its vertical length is shorter than the diameter of the playing ball A. The position of the bottom plate 15 with respect to 12 is set so that the upper part of the play ball A supported by the bottom plate 15 falls into the ball storage cylinder 14 and is slightly lower than the upper surface of the rotary plate 12. The play ball A is falling.

  In the case shown in the drawing, the hopper 11 is formed in a plane rectangular shape, and the rotating plate 12 is disposed at the position of the horizontal bottom 17 provided at a position offset from one corner at the bottom of the hopper 11, and the two sides of the horizontal bottom 17 are arranged. The bottom portion that is connected to is an inclined bottom portion 18 that is lowered toward the rotating plate 12, and the game balls A roll and gather toward the rotating plate 12.

  The play ball A does not fall directly into the ball storage cylinder 14 in a phase located directly above the ball take-out port 16 above the ball take-out port 16 above the rotating plate 12 inside the hopper 11. Further, a cover plate 19 that covers the upper portion of the ball storage cylinder 14 is disposed.

  The cover plate 19 is arranged by being fixed to the inner surface of the peripheral wall of the hopper 11 and is sized so as to cover the upper portion of the phased ball storage cylinder 14 positioned immediately above the ball outlet 16 as shown in FIG. As shown in FIG. 1, the height position of the cover plate 19 with respect to the rotating plate 12 is set directly above the ball outlet in a state where the ball A is superimposed on the game ball A dropped into each ball storage cylinder 14. When it moves toward the top, it is fixedly arranged at a height position where it can be removed upward when the upper game ball A rides on it at a position just above the ball outlet 16. The two game balls A are not taken out continuously.

  The cover plate 19 is fixed to the inner surface of the peripheral wall of the hopper 11, and is a tip portion facing directly above the phased ball storage cylinder 14 positioned immediately above the ball outlet 16, and is upstream of the rotation direction of the rotary plate 12. In a state where a cover plate body 21 provided with a notch 20 in which the entry side of the play ball A is inclined and widened at a position closer to the side and the entry side of the play ball A of the notch 20 is left, A movable lid 23 that is formed in a rectangular shape that closes the notch 20 and is attached to the cover plate main body 21 by a hinge 22 so as to open and close the main part of the notch 20, and one end of the hopper 11 or the cover plate main body 21. The other end is fixed to the movable lid 23, and the movable lid 23 is configured to include an elastic member 24 that urges elasticity so that the notch 20 is always closed. Prevention plate It made.

  The movable lid 23 has a tip corner portion on the ball entry side that is bent into an upwardly inclined piece 25 so that it is easy to escape upward when pushed by the play ball A, and the tip at the exit side of the play ball A. The tongue piece 26 provided at the corner portion is placed on the cover plate main body 21, so that the notch 20 is held in a closed position. The notch 20 is configured such that the entry side of the game ball A is opened by the inclined edge with respect to the movable lid 23 so that the game ball A directly enters the movable lid 23.

  A ball bridge prevention device formed such that a cam cylinder 27 whose upper end is an inclined surface on the rotation axis on the upper surface of the rotary plate 12 is integrally erected and a vertical axis 29 is provided at one end of the horizontal axis 28. 30 is installed in the hopper 11 with its longitudinal axis 29 fitted into the cam cylinder 27 and the lateral axis 28 supported by the inclined surface 27a.

  The ball bridge preventing device 30 has a length of the horizontal axis 28 so that the ball bridge preventing tool 30 does not rotate freely in the hopper 11 having a planar square shape, and a stirring arm 31 is provided on the middle of the horizontal axis 28. When the cam cylinder 27 rotates, the ball bridge prevention tool 30 held in an unstable state swings by the vertical movement of the horizontal shaft 28 by the inclined surface 27a, and moves the game ball A thrown into the hopper 11 up and down. By moving to, the occurrence of the bridging phenomenon of the game ball A is eliminated.

  A bendable ball stirring member 32 having a coil spring covered with a tube is attached to the outer periphery of the rotating plate 12, and the game balls A located around the rotating plate 12 are stirred when the rotating plate 12 rotates. I am doing so.

  The ball take-out device of the present invention has the above-described configuration. When a large number of play balls A are randomly placed in the hopper 11, the lower play balls A gather on the rotating plate 12 by the inclined bottom portion 18. In this state, when the rotating plate 12 is rotated clockwise as indicated by the arrow in FIG. 2, the game balls A that come into contact with the rotating plate 12 try to move in the rotating direction, thereby causing irregular movement. As a result, as shown in FIGS. 3 to 5, the game ball A falls into the ball storage cylinder 14 opened at the upper surface of the rotating plate 12 and is supported by the bottom plate 15.

  At this time, since the upper part of the phased ball storage cylinder 14 positioned directly above the ball outlet 16 is covered with the cover plate 19, the game ball A directly falls even when the ball storage cylinder 14 is empty. There is nothing.

  As described above, when the rotating plate 12 rotates, the game ball A that has fallen into the ball storage cylinder 14 at the position not covered by the cover plate 19 is carried toward the ball outlet 16 and is rotated. When the moving ball storage tube 14 faces directly above the ball take-out port 16, the game ball A in the ball storage tube 14 falls to the ball take-out port 16 and is taken out.

  The game ball A dropped and taken out from the ball outlet 16 is not shown, but is supplied to, for example, a subsequent washing machine.

  In taking out the game ball A as described above, as shown in FIGS. 6 to 9, with the game ball A overlapping the ball storage cylinder 14 in which the game ball A has fallen, directly above the ball outlet 16. , The upper game ball A rides on the movable lid 23 of the cover plate 19 and is removed upward, so that the two game balls A are not taken out continuously. ing.

  Further, as shown in FIGS. 10 to 14, when the game ball A is taken out as described above, the game ball is formed between the upper end opening edge of the empty ball storage cylinder 14 and the entrance side end edge of the cover plate 19. When A is sandwiched, the movable lid 23 in which the inclined piece 25 is pushed upward by the game ball A opens the game ball A against the elastic member 24 to escape, When the game ball A moves or falls into the ball storage tube 14, the movable lid 23 returns to the closed position of the notch 20, and the game ball A between the upper end opening edge of the ball storage tube 14 and the cover plate 19 is moved. Occurrence of pinching is prevented, so that the rotating plate 12 does not stop and the play balls A can be accurately taken out at regular intervals.

  When the cam cylinder 27 rotates during the rotation of the rotating plate 12, the ball bridge prevention tool 30 held in an unstable state is swung by the vertical movement of the horizontal shaft 28 by the inclined surface 27a and put into the hopper 11. By moving the game balls A, the occurrence of a bridge phenomenon in which the game balls A cannot move when they are stretched with each other in the hopper 11 is eliminated, whereby the entire game balls A in the hopper 11 can be taken out. it can.
