By the way, if a conveyor belt used in a dolly feeder is used for a certain period of time, it needs to be worn or cut due to an accident. The entire machine must be pulled out of the pachinko island platform, the conveyor belt must be replaced, and pushed back into place. In the prior art described above in performing this work, it is necessary to accurately and firmly connect the introduction rod and the recovery rod. Slide the installation base plate in as if pushing it in, and instruct another worker to slide and move the other side of the pachinko island from the other side of the pachinko island while making a voice call so that the introduction 樋 and the collection 樋 match exactly. In addition, a connection auxiliary tool was attached to secure the connection state when the introduction rod and the recovery rod matched. On the other hand, at the time of the drawing work, after removing the connection auxiliary tool from the opposite side of the pachinko island base, the installation base plate was slid so as to pull out the entire ball feeder. As described above, the prior art has a drawback that it is necessary to perform a very troublesome work when the ball feeder is taken in and out. The present invention has been made in view of the above-described circumstances, and its object is to provide a pachinko island stand equipped with a ball lifter capable of easily performing the work of entering and exiting the ball lifter. It is in.

In order to achieve the above object, in the invention according to claim 1,
In pachinko islands where a plurality of pachinko machines are lined up in the back and a ball feeder is erected in the middle of the pachinko machine,

The Rukoto Slide moves along the front Symbol installed base plate to a predetermined guide rail, the recovery gutter and the connection release state can not exchange exchange capable connected state and Ball of the ball with the introduction trough It is characterized by doing .

Left and right collection baskets provided opposite to each other so as to be linear in a plan view so as to collect used balls in a plurality of rows and gather at the approximate center of the pachinko island stand, and a ball feeder Introduced to the installation base plate via a mounting base in a direction perpendicular to the left and right recovery rods in a plan view, and receives the balls merged by the left and right recovery rods on the downstream side and supplies them to the ball feeder And a connection state in which balls can be exchanged between the collection rod and the introduction rod and a connection release state in which balls cannot be exchanged by sliding the installation base plate along a predetermined guide rail. Therefore, it is possible to carry out the work of taking in and out the ball feeder without worrying about the direction of the introduction rod .

  An embodiment of the present invention will be described below with reference to the drawings. First, the configuration of the pachinko island platform 1 to which the introduction rod 20 according to the embodiment is applied will be described with reference to FIG. FIG. 7 is a schematic perspective view showing the internal structure of the center portion of the pachinko island platform 1. In the figure, as is well known, the pachinko island platform 1 is constructed of a large number of horizontal rails 2 and vertical rails 3 to form a substantially rectangular parallelepiped shape, and a plurality of pachinko machines (not shown) are formed on both side surfaces in the longitudinal direction. ). A ball feeder 10 is erected in the approximate center of the pachinko island platform 1. Also, storage tanks 4 for storing a large amount of pachinko balls used in the pachinko island platform 1 are installed at the lower part of the pachinko island platform 1 and on the left and right sides of the ball feeder 10. A collection basket 5 is connected so as to be handed over. In addition, although this collection trough 5 is not shown in figure, it is extended to the edge part of the pachinko island stand 1. Therefore, the relationship between the storage tank 4 and the recovery basket 5 in the present embodiment is as follows. The used balls discharged from the pachinko machine installed on the pachinko machine 1 flow down the collection basket 5, but when the number of balls flowing down decreases, the balls stored in the storage tank 4 are collected. To be replenished. That is, when there are enough used balls discharged from the pachinko machine, the balls stored in the storage tank 4 are not replenished to the recovery basket 5, and the used balls discharged from the pachinko machine have been insufficient. Sometimes, the balls stored in the storage tank 4 are replenished to the collection basket 5.

  The bottom surface of the recovery basket 5 is an inclined bottom surface of a basket (see FIG. 1) so that the balls that flow down flow smoothly, and a rectangular drop opening 6 is opened at the lowest part. . Therefore, the balls that have flowed down the left and right recovery rods 5 fall downward from the drop opening 6, but below that, the ball receiving portion 31 of the introduction rod 20 is located and receives the falling balls as will be described later. The ball is guided to the lower part of the ball feeder 10. Therefore, the configuration of the ball hoisting machine 10 will be described first. In the ball hoisting machine 10 in this embodiment, the endless conveying belt 12 is erected in the vertical direction in the vertical direction by the lower drive pulley 13 incorporating the motor. A ball which is driven to rotate along both sides of the lifting cylinder 11 and is guided by the frictional force of the conveying belt 12 through the introduction rod 20 and the inflow arc rod 19 (see FIG. 4) is placed on one surface side of the lifting cylinder 11. It is lifted while being contact-polished by a polishing cloth (not shown) mounted on the provided polishing cloth mounting door 14 and finally discharged from the discharge port 18 at the upper end. Note that the belt tension of the conveyor belt 12 is adjusted by a tension roller 15 provided at a lower portion of the feeding cylinder 11. Further, the lifting cylinder 11 is erected on an upper portion of a support box 16 formed integrally with the installation base plate 17. The lower drive pulley 13 is rotatably supported inside the support box 16. The installation base plate 17 supports the entire ball lifting machine 10 and moves the installation base plate 17 along a predetermined guide rail (not shown) fixed to the floor surface. The entire machine 10 can be pulled out from the pachinko island stand 1 or pushed into the pachinko island stand 1.

  By the way, the polished balls discharged from the discharge port 18 are temporarily stored in an upper storage tank (not shown), and then flow out from a replenishment rod (not shown) connected to the bottom surface of the upper storage tank. The replenishment trough is provided in an inclined shape from the upper storage tank toward both ends of the pachinko island platform 1, and is provided on the back upper part of each pachinko machine by a shunt provided in the middle corresponding to each pachinko machine. It is supplied to a well-known prize ball tank. In addition, a return pipe is connected to the upper part of the middle of the upper storage tank. This return pipe uses less prize balls in the pachinko machine and eliminates the need to supply balls to the supply basket. When the number of balls stored in the storage tank increases, excess balls are returned to the storage tank 4.

  In the pachinko island stand 1 configured as described above, the balls polished and lifted by the ball lifting machine 10 are supplied to each pachinko machine through a replenishing rod, while the used balls used in each pachinko machine are used. The balls are collected by the ball feeder 10 by the collection basket 5, polished and lifted again, and supplied to the supply basket. That is, the balls are circulated within the pachinko island platform 1. Thus, in order to connect the left and right recovery rods 5 inclined from the end of the pachinko island base 1 toward the center and the inflow arc rod 19 of the ball hoisting machine 10, it is orthogonal to the recovery rod 5. It is necessary to provide the introduction rod 20 on the extension of the inflow arc rod 19. Therefore, the relationship between the collection basket 5 and the introduction basket 20 will be described below with reference to FIGS. 1 and FIG. 2 are plan views showing the relationship between the recovery rod 5 and the introduction rod 20, and FIG. 3 is a partial perspective view showing the relationship between the collection rod 5 and the introduction rod 20. 5 is a side view showing the relationship between the collection basket 5 and the introduction basket 20, and FIG. 6 is an exploded perspective view of the introduction basket 20.

  In the figure, the collection basket 5 and the introduction basket 20 are arranged overlapping in a vertical step shape so that the collection basket 5 is upward in the orthogonal direction, and balls are placed on the collection basket 5 in the overlapping portion. The dropping port 6 that falls is formed. By the way, as shown in FIG. 6, the introduction rod 20 is composed of a lower introduction rod 21 and an upper introduction rod 22 formed of synthetic resin, and by fixing the upper introduction rod 22 to the lower introduction rod 21, The introduction rod 20 is integrally configured as a whole. Therefore, first, the configuration of the lower introduction rod 21 will be described. The ball introduction rod 23 having a plurality of partition walls 24 standing at intervals slightly larger than the diameter of the balls is provided on the upper portion of the lower introduction rod 21. The ball guide rod 23 is attached to a mounting base 25 formed in an approximately L shape. A specific mounting structure is such that the upstream side rear surface of the ball guide rod 23 is pivotally supported by a mounting shaft 26 (see FIG. 4), and both downstream sides of the ball guide rod 23 are supported by inclination adjusting screws 27. Has been. Therefore, the optimum inclination angle of the ball guide rod 23 can be adjusted by adjusting the inclination adjusting screw 27. The inclination adjusting screw 27 is provided with a coil spring so that the adjusted inclination angle can be accurately maintained even after a long period of time. Even if the ball that flows down at the connecting portion with 19 is in a clogged state, the clogged state is eliminated by the elastic force of the coil spring.

  Further, the downstream side of the ball guide rod 23 has an arc shape so as to follow the shape of the outer peripheral surface of the lower drive pulley 13 when the mounting base 25 is fixed to the installation base plate 17. Furthermore, hook-shaped engagement pieces 28 are formed on both sides of the back surface of the downstream end of the ball guide rod 23, and the ball guide rod 23 is secured when the mounting base 25 is fixed to the installation base plate 17, as shown in FIG. The starting end of the inflow arc ridge 19 is held by the downstream end of the boss and the engagement piece 28. Thus, the connection between the inflow arc rod 19 and the downstream portion of the introduction rod 20 is performed accurately and reliably. On the other hand, a joint portion 29 for joining the upper introduction rod 22 is formed on the upstream side of the ball guide rod 23. The joining portion 29 is formed in a stepped shape so as to overlap with the downstream end portion of the upper introduction rod 22, and joining holes 30 are formed on the left and right sides of the bottom of the stepped portion.

  In the upper introduction rod 22 to be joined to the lower introduction rod 21 having the above-described configuration, the entire shape is formed in a box shape with the upper part opened, and the upper surface edge faces the perpendicular portion facing the outer periphery of the recovery rod 5. 35, and its bottom surface is inclined. Note that the vertical portion of the right-angled portion 35 is an abutting portion 35a. As is apparent from FIGS. 2 and 5, the abutting portion 35a abuts on the front side of the collection basket 5. Thus, the position of the introduction rod 20 can be adjusted. The upstream portion of the bottom surface is a ball receiving portion 31 that receives a ball falling from the dropping port 6, and a partition start end wall 32 that constitutes the start end portion of the partition wall 24 on the downstream side of the ball receiving portion 31. Is erected. The partition start end wall 32 is formed in a substantially triangular shape. In addition, the joining pin 33 can be inserted and screwed at a position corresponding to the joining hole 30 in the downstream portion of the bottom surface. Further, on the back surface of the bottom surface, a supporting piece 34 is suspended which contacts the standing wall of the mounting base 25 and receives the load applied to the ball receiving portion 31 when the upper introduction rod 22 is fixed to the lower introduction rod 21. .

  The downstream portion of the upper introduction rod 22 configured as described above is superposed on the joint portion 29 of the lower introduction rod 21, and the joining pin 33 is screwed into the joining hole 30 in this state, whereby the upper introduction rod 22 and the lower introduction rod 22 are The introduction rod 21 can be assembled integrally with the introduction rod 21, and a plurality of partition walls 24 (32) for aligning balls in a row are provided on the downstream side of the introduction rod 20, and Since the ball receiving portion 31 for receiving the ball falling from the dropping port 6 of the recovery basket 5 is formed on the upstream side, and the mounting base 25 is fixed to the installation base plate 17, the ball lifting machine 10 It is in a state of being integrally attached to.

  Thus, the operation of the introduction rod 20 that is integrally fixed to the ball feeder 10 will be described with reference to FIGS. 1 and 2 and FIGS. 4 and 5. FIG. As shown in FIG. 5, the drop port 6 of the recovery rod 5 and the ball receiving portion 31 of the introduction rod 20 are overlapped in the vertical direction. For this reason, the used balls that flow down the collection basket 5 fall from the drop opening 6 to the ball receiver 31, and are then aligned by the partition wall 24 (32) and guided to the inflow arc basket 19. Is raised by. Further, in the state where the drop port 6 and the ball receiving portion 31 overlap with each other, the facing right angle portion 35 of the introduction rod 20 is in a state of being substantially in contact with the bottom surface from the front side surface of the recovery rod 5. Falling balls will not leak outside.

  On the other hand, when it is necessary to replace the conveyor belt 12 of the ball hoisting machine 10, it is necessary to pull out the entire ball hoisting machine 10 from one side surface of the pachinko island base 1. In this case, Since the introduction rod 20 and the collection rod 5 are not connected by a special connection aid, if the ball lifting machine 10 is pulled out, the installation base plate 17 can be easily pulled out by sliding against the floor surface. (State shown in FIGS. 1 and 4). Then, when the replacement operation of the conveyor belt 12 is completed and the ball feeder 10 is stored again in the pachinko island platform 1, the entire ball feeder 10 is pushed in so that the installation base plate 17 is moved against the floor surface. And slide it into place. Then, the facing right angle portion 35 of the leading end portion of the introduction rod 20 is in a state of substantially contacting the bottom surface from the front side surface (the state shown in FIGS. 2 and 5), and the drop port 6 of the collection rod 5 and the ball receiving portion of the introduction rod 20 31 is in a connection state in which balls can be exchanged. In this connection state, the connection state is maintained sufficiently firmly and accurately without using a special connection auxiliary tool.

  As described above, in this embodiment, the ball receiving portion 31 of the introduction rod 20 is merely inserted below the drop port 6 of the recovery rod 5, and therefore special when the ball feeder 10 is taken in and out. It is not necessary to perform a simple connection work or a connection release work, and a single worker can carry out the entry / exit work of the ball lifter 10 from the side where the ball lifter 10 is taken in / out. In particular, the pachinko island platform 1 is not a pachinko machine lined up backwards, but an island wall type pachinko island board with pachinko machines arranged only on one side (may be installed along the wall in the amusement park) In many cases, it was necessary to configure a passage through which people could pass between the back of the pachinko island stand and the wall of the amusement hall for the entrance and exit work of the ball feeder 10. By configuring as shown in the example, the pachinko island platform in the form of an island wall can be installed in close contact with the wall of the game arcade without the passage, so that the floor of the game arcade can be used effectively.

  In the above-described embodiment, the introduction rod 20 is configured by integrally assembling the lower introduction rod 21 and the upper introduction rod 22. However, the introduction rod 20 may be integrally formed from the beginning. Instead of a synthetic resin, another material (for example, a metal plate) may be used. Further, in the above-described embodiment, the structure for stopping the balls of the recovery basket 5 when the ball lifting machine 10 is pulled out has not been described. 6 may be configured to be closed, or a stopper member that drives the closing plate that closes the drop port 6 by pushing a switch before starting the drawing operation, or stops the balls of the collecting basket 5 from flowing down. You may make it drive.
