Description

  The present invention is provided on a pachinko machine island, and is a polishing machine that polishes pachinko balls collected from a pachinko gaming machine island or ball counter, etc., in a lower storage section in the pachinko gaming machine island while pumping up to an upper storage section. Relates to the device.

  In the amusement hall, there are a plurality of gaming machine islands that are formed by connecting pachinko machines in series, and each of the lifting and polishing apparatuses that polish the pachinko balls stored in the lower storage part while lifting them to the upper storage part. It is installed on Pachislot Island.

  In the conventional lifting and polishing apparatus, one side of the door body provided with a ball feeding guide is fixed to the side opposite to the conveyor belt with a polishing cloth on one side of the main body including the conveyor belt by a plurality of hinges. And the other side part side of a door body can be opened and closed laterally by making the other side part of a door body detachable to the other side part of this main body with a fixture. Therefore, when the door body is closed with respect to the main body, the door body is fixed between the main body and the door body by one side portion fixed to the main body by a hinge and the other side portion detachably attached by a fixing tool. A difference occurs in the pressing force between the pachinko balls that rise on the hinge side and the pachinko balls that rise on the fixture side between the conveyor belt and the polishing cloth, so that the polishing unevenness is not sufficiently removed. There was a problem.

  Also, there are multiple rows of guide grooves that guide the pachinko balls upward on the surface of the ball feed guide that faces the conveyor belt, but the pachinko balls rub against the door body at the ends of both sides of the ball feed guide. Therefore, the guide groove cannot be formed. Therefore, both end portions of the ball feed guide where the pachinko ball does not rise during operation of the lifting and polishing apparatus may bend toward the conveyor belt. As a result, the central portion of the ball feed guide rises away from the conveyor belt, and uneven polishing occurs between the pachinko ball that rises at the central portion of the ball feed guide and the pachinko ball that rises at both ends. As a result, there was a problem that the dirt on the pachinko balls could not be removed sufficiently.

  For example, in Patent Document 1, a spring is attached between the door body of the lift polishing apparatus and the ball feed guide to solve the above problem, so that the pachinko balls that rise between the conveyor belt and the polishing cloth are uniform. A lift polishing apparatus is disclosed that prevents polishing unevenness by applying pressure to the surface.

FIG. 1 is a view showing a pachinko machine island and a lifting and polishing apparatus provided there, FIG. 2 is an enlarged view of the lifting and polishing apparatus of FIG. 1, and FIG. 3 is when the door body is opened. FIG. 4 is a view showing a lift polishing apparatus (a state where a polishing cloth is removed), and FIG. 4 is a view showing a fixed state of the door body to the main body of the lift polishing apparatus.

  As shown in FIG. 1, generally, in a game arcade, a row called a pachinko gaming machine island 20 formed by connecting pachinko gaming machines 2 is formed. It is taken in from the ball counting machine 4 installed on the island edge of the pachinko gaming machine island 20 or discharged from the pachinko gaming machine 2 to the lower reservoir 22 provided at the lower part of the pachinko gaming machine island 20. A lifting and polishing device 10 that polishes the recovered pachinko balls 1 while lifting them to an upper storage portion 21 provided on the upper portion of the pachinko gaming machine island 20 is provided at the center of the pachinko gaming machine island 20. .

  At the lower part of the pachinko gaming machine island 20, a lower conveyance path 24 that is inclined downward from both ends of the pachinko gaming machine island 20 toward the central lower storage part 22 is extended. The pachinko balls 1 that have flowed down to the lower conveyance path 24 like the out balls from the pachinko gaming machine 2 are collected into the lower storage section 22 according to the inclination of the lower conveyance path 24 and introduced into the lifting and polishing apparatus 10. In addition, the lower conveyance path 24 is not limited to one configured by a single inclination from both ends of the pachinko gaming machine island 20 toward the central lower storage part 22, but in the case of a long pachinko gaming machine island 20, an appropriate In some cases, a small lifting device 27 is incorporated in the middle to ensure the inclination (see FIG. 1).

  The pachinko ball 1 that has flowed into the lower part of the lifting and polishing apparatus 10 from the lower reservoir 22 is provided with a polishing cloth 11 and a conveyor belt 14 attached along a guide surface of a ball feed guide 12 provided on the back surface of the door A. And is transported to the upper reservoir 21 while being guided to the guide groove 13 of the ball feed guide 12 by the upward rotation of the conveyor belt 14 (see FIG. 4).

  The pachinko balls 1 lifted to the upper storage part 21 are arranged on the pachinko machine island 20 through the upper conveyance path 23 inclined downward from the upper storage part 21 toward both ends of the pachinko machine island 20. It is supplied to the pachinko machine 2 and the ball lending machine 3. The pachinko balls 1 that have reached both ends of the pachinko machine island 20 are discharged from the upper conveyance path 23 to the lower conveyance path 24 through the discharge hose 25 that hangs downward. Further, out balls generated by playing a game using the pachinko balls 1 lent out from the ball lending machine 3 are also discharged to the lower conveyance path 24 of the pachinko gaming machine island 20. In addition, when the player finishes the game in a state of winning a ball with a jackpot or the like, the ball counter 4 provided on the island edge of the pachinko gaming machine island 20 counts the acquired ball. The pachinko balls 1 are discharged to the lower conveyance path 24 of the pachinko machine island 20 via the ball counter 4. Thus, the pachinko balls 1 accumulated in the lower conveyance path 24 are circulated and used in the pachinko gaming machine island 20 by being polished and lifted through the lift and polish device 10.

  In order to prepare for the jackpot of the pachinko machine 2 installed on the pachinko machine island 20 and the replenishment of the lending request of the ball lending machine 3, the lifting and polishing device 10 moves from the lower storage part 22 to the upper storage part 21. The amount of the pachinko ball 1 to be lifted and polished is larger than the amount of the pachinko ball 1 sent from the upper reservoir 21 to the upper conveyance path 23, and the upper reservoir 21 is always filled with the pachinko ball 1. It is in the state. Therefore, an overflow hose 26 directly connected to the lower reservoir 22 is installed in the upper reservoir 21 so that the pachinko ball 1 filled in the upper reservoir 21 is not clogged with the lifting and polishing apparatus 10. When the pachinko ball 1 stored in the upper storage part 21 reaches a certain amount, it flows down to the lower storage part 22 through the overflow hose 26.

  As shown in FIGS. 2 and 3, the conveyor belt 14 provided in the lifting and polishing apparatus 10 is moved oppositely by a motor unit (not shown) provided at the lower part of the lifting and polishing apparatus 10. The guide 12 is rotationally driven in the upward direction. Further, the polishing pad 11 is wound around and attached to a cloth feed guide 16 provided at the lower part of the surface of the door body A. Then, the polishing cloth 11 drawn out from the cloth feed guide 16 is laid upward along the surface of the door body A, folded back at the top of the door body A, and fed to the back of the door body A. It is laid downward along the guide 12, folded back at the lower part of the door body A, and taken up by the cloth winding unit 17 provided at the lower part of the surface of the door body A.

  When the lift polishing apparatus 10 is operated, the polishing cloth 11 soiled by the polishing of the pachinko balls 1 lifted between the polishing cloth 11 pressed against the conveying belt 14 by the ball feeding guide 12 and the conveying belt 14 is obtained. By rotating and driving the cloth winding unit 17, a dirty portion facing the ball feed guide 12 is taken up so that the unused polishing cloth 11 drawn out from the cloth feed guide 16 contacts the ball feed guide 12. Become. Then, the polishing cloth 11 that has been soiled after being used for polishing is finally wound up in a roll shape by the cloth winding unit 17.

  Further, as shown in FIG. 4, a fixed body having a function of urging the door body A to the main body B provided at a plurality of positions on both sides of the lift polishing apparatus 10 with the door body A of the lift polishing apparatus 10. You may fix to a main body with a tool (henceforth, elastic fixing tool 15). In this case, the elastic fixing tool 15 used is a known member constituted by a fixing member, an attaching member, a hooking member, and a coil spring as an urging member, and is attached close to the fixing member attached to the main body B. A coil spring is interposed between the member and the fixing member, and the coil spring that is extended when the attachment member is hooked to the hook member attached to the door body A uses the spring pressure that retracts the attachment member toward the fixing member and contracts. Thus, the door body A is fixed to the main body B. By fixing the door body A to the main body B using the elastic fixing tool 15, moderate elasticity can be maintained between the main body B and the door body A even after the fixing. As a result, the variation in the pressing force applied to the surrounding members by the pachinko balls 1 lifted between the polishing cloth 11 and the conveying belt 14 pushed by the ball feed guide 12 is absorbed by the coil spring of the elastic fixing tool 15. By making it uniform over the entire surface of the ball feed guide 12, the pachinko ball 1 can be uniformly polished.

  In the present invention, if the ball feeding guide 12 that absorbs the variation in the pressing force to the surrounding members by the pachinko balls 1 to be fed is provided in the door body A, the main body B and the door of the lifting and polishing apparatus 10 A fixture that does not include an elastic member may be used to fix the body A. Further, the elastic member provided on the elastic fixing member 15 is not limited to the coil spring but may be formed by a tension spring, a compression spring, or the like as long as it has a function of urging the main body B against the door body A. Here, the door body A provided with the ball feeding guide 12 that absorbs the variation in the pressing force uses a resin material or a rubber material having elastic force for the ball feeding guide 12, or the ball feeding guide 12 having no elastic force. What is necessary is just to provide the function which can absorb the dispersion | variation in the pressing force added to the ball | bowl feed guide 12 by providing a rubber member which has a spring member or elastic force between the door body A.
