[Industrial applications]

 The present invention relates to a pumping mechanism in an island stand in which a reducing machine pumping mechanism and an island table mechanism are provided as a unit by providing a connecting portion for each of the sending balls.

[0002]

[Prior art]

 Conventionally, the out discharge balls discharged from the pachinko machine are collected by an out gutter provided in a V shape on the waist of the island stand, and the collected balls are ground and pumped by a reducing machine installed in the center of the pachinko island stand. It is configured by an automatic ball circulation mechanism that supplies each pachinko machine again via the supply gutter. In the automatic ball circulation mechanism, the balls flowing down from the out gutters on the left and right of the island stand, which form the most important part, must be collected in one place, and a recovery gutter that efficiently supplies the balls to the reducing machine ball introduction part in the center of the island stand must be formed. Since there is no need to do so, there is no level difference between the start end of the recovery gutter and the end ends of the outer gutters on the left and right island stands, and the connection work is made horizontally and the bottom surface is appropriately inclined with a proper inclination, and the fixed positions of the recovery gutter and the ball receiving gutter are fixed. The connecting work was a recovery gutter erection work while calculating the flow gradient of the balls, and required skilled skills and many construction days. In addition, if maintenance work on the restoration machine and replacement work due to cutting of the lifting belt occur, take out the reducing machine to the outside of the island stand or perform maintenance work, or replace the new lifting belt, and then move to the prescribed position described above. It is difficult to adjust the collection and installation of the collection gutter and the ball receiving gutter in the plant, and it is impossible to maintain the pumping amount above the specified amount due to equipment consumption due to poor adjustment and unnecessary running costs. However, there was a shortage of replenishment balls, and the connection work was adjusted again, and the work wasted a lot of time. In addition, on one side of the island stand, which is commonly known as the wall island, a space for connecting ball passages and maintenance must be secured in advance on the back wall side of the island stand, and an unnecessary space for the hole area must be provided. It was

[Action]

 Since the reducing machine BOX1 is interposed between the island stands S, S, the starting end of the collecting trough 2 and the end of the island stand out gutter 3 which are formed at the same height as the island stand out gutter 3 in advance are accurately formed. They are connected by position setting, and the upper end of the supply tank H and the start end of the supply trough M are also connected at a fixed position to form a series of island stands S. A ball receiving part 17 of a ball receiving gutter 16 connected to the reducing machine ball introducing part 15 is accurately installed in the drop opening 6 of the recovery gutter 2 connected in this way by providing a drop play with a small ball diameter. It

The out balls discharged from the pachinko machine P by opening a ball stopper (not shown) mounted on the collection gutter 2 are aligned in a row by a ball passage having an appropriate slope and drop in flow velocity. The balls flowing from the left and right recovery gutters 2 collide with each other at the center of the drop port 6 which is formed with a suitable step and are decelerated to reduce the flow velocity and diffused in all directions and formed with a slight gradient in the downstream direction. The balls accumulated in the receiving section 17 are in a horse riding state in the upper stage, and in the lower stage, the course of the balls is selected again by the partition wall 18 while competing while changing the direction by 90 degrees by pressing from the top, and the reducing machine ball introducing section. You will be guided to 15. A plurality of pachinko machines P and ball lending machines (illustrated in the figure) arranged in a back row on the island stand S after being ground and pumped by the reduction machine K and sent to the replenishment tank H to become replenishment balls again to flow down the replenishment gutter M. Balls are sent to (omitted). When the return machine 1 is pulled out from the reduction machine BOX1 and is serviced and the lifting belt is replaced, it is guided to the rails of the fixed plate 20 laid on the bottom surface of the reduction machine BOX X1 and led out to the hall passage outside the island stand S. At that time, the recovery gutter 2 installed on the reducing machine BOX1 side and the ball receiving gutter 16 installed on the reducing machine K side are automatically separated.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view in which a reduction machine BOX1 having a reduction machine K housed in a central portion of an island stand S in which a large number of pachinko machines P are arranged side by side is detachably interposed. The reducing machine BOX1 has a ball passage integrally formed inside the reducing machine BOX at a position where the inflowing balls can be gathered together with the islanding out gutter 3 provided in advance at the waist of the islanding stand S. It is configured to form a series of island stands S by interposing X1 and will be described in detail with reference to FIGS.

First, in detail from the recovery gutter 2, a recovery gutter 2 that is substantially horizontal and has the same length in the width direction of the reducing machine BOX 1 and the height of the terminal ball outlet 4 of the island stand outer gutter 3 is installed. To do. The bottom of the gutter of the collecting gutter 2 is formed by a slatted ball passage 5 in which balls are aligned in a line between the grooves, and the balls led out in a mountain shape from the island stand out gutter 3 are provided on the bottom. Grooves form ball passages 5 that quickly add balls and add flow velocity. The collection gutter 2 is formed in a substantially V shape, which descends from the left-right direction to the center, and is obliquely formed, and a drop port 6 is formed at the center of the end of the collection gutter 2. A mounting portion 8 is formed at both start ends of the collecting trough to serve as a screw fixing portion to the inner wall surface of the reducing machine BOX1. A connection opening is formed on both side walls of the reducing machine BOX1 so as to be connected to the recovery gutter 2 so that the terminal ball outlet 4 of the island stand out gutter 3 provided on the side surface of the island stand S is connected at a fixed position. A ball stopper (not shown) is provided at an appropriate position of the recovery gutter 2 so that the flowing-down ball can be manually or automatically stopped.

Next, a ball receiving trough 16 which is integrally attached to the reducing machine ball introducing portion 15 and which can be freely attached to and detached from the drop opening 6 of the recovery gutter 2 will be described. The ball receiving trough 16 has a slightly larger area than the drop opening 6 to form a ball receiving portion 17 so as to completely receive the falling ball from the drop opening 6, and the ball receiving portion 17 has a step on the lower surface of the drop opening 6. By connecting them in a stacked manner, the balls flowing down at high speed from the left and right directions are temporarily decelerated at the stepped portion and are formed to change direction at a right angle. The space between the drop port 6 and the ball has a small ball diameter that prevents balls from popping out, and a notch 16a at a right angle is provided on the ball receiving trough 16 so that the ball can be accurately positioned and fixed to the space that does not come into contact when the reducing machine K is attached or detached. The position where the cutout portion 16a abuts on the outer wall of the recovery gutter 2 during installation and installation is a fixed position.

Further, a partition wall 18 is erected in one side direction, which is a downstream side of the ball receiving portion 17, at a large ball diameter interval of the same number as that of the reducing machine ball introducing portion 15, and is continuous with the reducing machine ball introducing portion 15. It is fixed so that it becomes a ball passage. The shape of the mounting side surface of the ball receiving trough 16 is a substantially triangular shape, and a slope is provided toward the ball receiving portion 17 on the upstream side. Also, mounting bases 15a and 15b are provided upright on the bottom of the reducing machine ball introduction part 15 and the bottom of the ball receiving trough 16, respectively, and coil springs are installed around the mounting base support shaft, so that the tilt angle adjusted even after long-term use It is designed to be held accurately (see Figure 2).

The ball receiving trough 16 and the reducing machine ball introducing portion 15 may be provided with a lid fitted from above to provide a foreign matter introduction protection measure. Here, the flow state of the balls flowing down from the left and right recovery gutters 2 will be described. Balls flowing from the collection gutter 2 with a slope are piled up in a mountain shape by a ball receiving part 17 formed on the bottom surface with a plate-like shape and with appropriate steps, and once the flow velocity is reduced, the path of the ball is selected at 18 partition walls. However, the balls stacked in a stepped manner at the ball receiving part 17 formed with a slight gradient in the downstream direction, the upper stage is a horse riding state, the lower stage is a competition from the flow by pressing from the upper stage and again with the partition wall 18. The balls are guided in the reducing machine ball introducing section 15, but the pressing force of the balls due to the accumulation in the ball receiving section 17 urges the reducing machine ball introducing section 15 side substantially evenly, so that the feeding force necessary for the lifting force is provided. With the added effect, it is possible to pump a stable amount of balls at all times. The balls guided in this way are smoothly introduced from the reducing machine ball introducing section 15 to the reducing machine K.

Next, in order to hold the recovery gutter 2 and the ball receiving gutter 16 in a more accurate fixed position, a fixed plate 20 is laid on the bottom surface of the reduction machine BOX 1. The fixed platen 20 (see FIG. 5) forms a rectangular fixed platen base 21 coinciding with the bottom surface of the reduction machine BOX 1, and when the reducing machine K is mounted on the fixed platen base 21, the reduction machine The side stopper 30 is formed so that the ball receiving gutter 16 connected to the K side stops at a position directly below the drop port 6 of the collecting gutter 2 installed on the rear side. The guide fixture 32 is formed on the other side of the side stopper 30. Rails (not shown) are laid inside the side stopper 30 and the induction fixture 32 so that the reducing machine K can easily slide. A plurality of retainers 35 are provided on the side stopper 30 and the guide fixture 32 at both ends of the fixed board base 21.

Next, the reducing machine BOX1 forms a rectangular box having a height and a width that can accommodate the reducing machine K, has an opening at the front of the box, and has the image color and shape of the island stand S. The hatches 24A and 24B that have been decorated are divided into an upper part and a lower part that facilitate maintenance and inspection of the reduction machine K, and are hinged. The hatch 24 will be described as being divided but not limited thereto. Next, on the upper side surface of the reducing machine BOX1, a replenishment tank H for storing the pumped balls and a replenishment gutter M installed in advance on the island stand S are connected to each other so that the balls flow smoothly, The ball discharging portion 22 at the upper part of the machine K is provided so as to face the supply port of the supply tank H (see FIGS. 2 and 3).

The reducing machine BOX 1 configured as described above is provided with a plurality of pachinko machines P interposed in the middle of the island stands S, S arranged in a back row to form an automatic circulating ball mechanism. In this embodiment, the recovery gutter 2 is integrally provided inside the reducing machine BOX 1 but the present invention is not limited to this. For example, the recovery gutter 2 is attached to the island stand S in advance, and the recovery gutter 2 is installed. The lower part of the reducing machine BOX1, which is the installation location, may be configured as a notch and inserted from the front side, and it is needless to say that the design can be freely changed within the scope of the utility model registration claim.

[Effect of the present invention]

 As is apparent from the above description, according to the present invention, the collecting gutter is formed in advance on the reducing machine BOX side in the shape of the same height as the island stand out gutter, and the ball can be received at the fixed position at the end of the collecting gutter. As a result, the integrated ball passage is immediately constructed by connecting the reducer BOX to the connection work of the out ball collection gutter, so that the work can be done quickly even at a messy site, and the construction period for island stand formation can be shortened. Significantly shortened. By installing a fixed plate on the bottom of the reducer BOX, the reducer is brought out of the box, and after maintenance and inspection and replacement of the damaged belt, the reducer can be easily and accurately returned to its original position without any visual confirmation. Now that I can do it, I can work alone.

Since the position of the recovery gutter was accurately determined, the shape of the ball receiving gutter connected to the reduction machine introduction gutter was standardized, and the parts became standardized, enabling mass production.

Since the reduction machine can be transported while being housed in the reduction machine BOX, it is possible to prevent damage during transportation. By installing a reduction machine BOX on the wall island, it is not necessary to secure a space between the back of the wall island and the wall of the game arcade, and the distance between the islands can be widened.
