The introduction gutter is provided integrally on the installation base plate of the doffing machine, and has a structure in which the tip portion is curved in a V-shape and connected to the left and right collection gutters. [0003] By the way, the balls are not always uniformly supplied from the left and right collecting gutters to the doffing and feeding machine. For some reason, such as the amount of returned balls or a failure in the recovery gutter, the supply of balls to the doffer may be biased toward the supply from one recovery gutter, or no ball may be supplied from one recovery gutter. is there. In such a case, in the above-described prior art, the balls transferred from the left and right collection gutters are supplied to the doffing machine through the respective passages separately from the left and right without merging. When a ball is lifted by the ball doffing machine, the ball is also lifted off-center in the ball doffing machine. For this reason, the capacity of the ball-lifting machine is sufficient, such as a reduction in the amount of the conveyor belt for ball-lifting and the polishing cloth for polishing the balls, and the amount of balls less than the number of balls that can be lifted. There was a problem that it could not be used for The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an introduction gutter in a doffing machine capable of fully utilizing the capability of the doffing machine. In order to achieve the above object, according to the first aspect of the present invention, balls flowing from left and right collecting gutters for collecting used balls are supplied to a ball lifting machine. In the introduction gutter to be collected, the collected ball is located at the lowest part of the collection gutter.

The ball receiving portion is inserted at a position below the drop opening of the collecting gutter.
It is characterized in that the. With this configuration, the ball that has flowed into the introduction gutter from the collection gutter is temporarily received by the ball receiver, and then supplied to the doffer over the entire width direction of the doffer. It is possible to reduce the loss of the transfer belt and the polishing cloth, and to fully utilize the lifting capability of the doffing machine. In addition, when the doffing machine is moved and installed, the ball receiving portion of the introducing gutter is positioned below the dropping hole of the collecting gutter by a simple structure that is simply inserted until the contact portion of the introducing gutter contacts the collecting gutter. Since the connection work between the introduction gutter and the collection gutter can be performed extremely easily, a single worker can easily put the doffing machine in and out from the side that puts the doffing machine in and out. It can be carried out. In addition, since the load applied to the ball receiving portion by the ball that falls downward from the falling port of the collection gutter is received by the support piece,
An introduction gutter that is not damaged by the impact of the ball can be provided, and the support piece comes into contact with the mounting base of the lower introduction gutter, so that the upper introduction gutter can be supported by the lower introduction gutter. Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, the configuration of the pachinko island stand 1 to which the introduction gutter 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 central portion of the pachinko island stand 1. In the figure, as is well known, the pachinko island stand 1 is generally formed in a substantially rectangular parallelepiped shape by framing a number of horizontal rails 2 and vertical rails 3, and a plurality of pachinko machines (not shown) are provided on both sides in the longitudinal direction. ) Are arranged in reverse. In addition, a doffing and feeding machine 10 is erected substantially at the center of the pachinko island stand 1. In addition, a storage tank 4 for storing a large amount of pachinko balls used in the pachinko island stand 1 is provided below the pachinko island stand 1 and on the left and right of the doffing machine 10, and between the storage tanks 4. The collection gutter 5 is connected so as to be inserted. Although not shown, the recovery gutter 5 extends to the end of the pachinko island stand 1.
Thus, the storage tank 4 and the collection gutter 5 in the present embodiment
Is as follows. The used balls discharged from the pachinko machine installed on the pachinko island stand 1 are collected by a collecting gutter 5
The balls stored in the storage tank 4 are replenished to the collecting gutter 5 when the number of flowing balls is reduced. That is, when the used balls discharged from the pachinko machine are sufficient, the balls stored in the storage tank 4 are not replenished to the collecting gutter 5, and the used balls discharged from the pachinko machine have become insufficient. Sometimes, the balls stored in the storage tank 4 are replenished to the collection gutter 5. [0006] The bottom surface of the collecting gutter 5 is a slanted bottom (see FIG. 1) so that the flowing balls can flow smoothly.
Has been established. Therefore, the balls that have flowed down the left and right collecting gutters 5 fall down from the falling ports 6, and below them, the ball receiving portions 31 of the introduction gutters 20 are located as described below to catch the falling balls. The balls are guided to the lower part of the doffer 10. Therefore, the configuration of the doffing machine 10 will be described first. In the doffing machine 10 in the present embodiment, an endless transport belt 12 is erected in the vertical direction by a lower drive pulley 13 having a built-in motor. The transport belt 12 is driven to rotate along both sides of the lifting cylinder 11,

While being polished in a contact manner, and finally discharged from the discharge port 18 at the upper end. The belt tension of the transport belt 12 is adjusted by a tension roller 15 provided below the lifting cylinder 11. The lifting cylinder 11 is provided upright on 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 doffing machine 10, and is installed along a predetermined guide rail (not shown) fixed to the floor.
By moving 7, the entire doffing and feeding machine 10 can be pulled out from the pachinko island stand 1 or pushed into the pachinko island stand 1. The polished balls discharged from the discharge port 18 are temporarily stored in an upper storage tank (not shown), and then flow out of a supply gutter (not shown) connected to the bottom surface of the upper storage tank. I do. The supply gutter is provided in an inclined manner from the upper storage tank toward both end portions of the pachinko island stand 1, and is provided at an upper part on the back of each pachinko machine by a flow divider provided corresponding to each pachinko machine in the middle thereof. It is supplied to a well-known prize ball tank. In addition, a return pipe is connected slightly above the middle of the upper storage tank, and this return pipe uses less prize balls in pachinko machines, eliminating the need to supply balls to the supply gutter,
As a result, when the number of balls stored in the upper 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 fed by the ball hoisting machine 10 are supplied to each of the pachinko machines via the supply gutters, while the balls are used in each of the pachinko machines. The used balls are collected in the ball lifting machine 10 by the collecting gutter 5 and polished and fed again to be supplied to the supply gutter. That is, the balls are circulated and used inside the pachinko island stand 1. Thus, the left and right collecting gutters 5 and the doffing machine 10 which are installed at an angle from the end of the pachinko island stand 1 toward the center.
In order to connect the inflow arc gutter 19 with the inflow arc gutter 19, the introduction gutter 2

A support piece 34 that abuts against the upright wall of the mounting base 25 when the 2 is fixed to the lower introduction gutter 21 and receives the load applied to the ball receiving portion 31 is hung down. The downstream portion of the upper introduction gutter 22 constructed as described above is overlapped with the joining portion 29 of the lower introduction gutter 21, and a joining pin 33 is screwed into the joining hole 30 in this state, whereby an upper introduction gutter is formed. 22 and the lower introduction gutter 21 can be integrally assembled. The introduction gutter 20 thus integrally assembled is provided with a plurality of partition walls 24 (32) on the downstream side thereof in which balls are arranged in a line. A ball receiving portion 3 provided at an upstream side thereof for receiving a ball falling from a dropping port 6 of a collecting gutter 5.
1 is formed, and the mounting base 25 is fixed to the installation base plate 17, so that the mounting base 25 is integrally fixed to the doffing and feeding machine 10. The operation of the introduction gutter 20 integrally fixed to the doffing and conveying machine 10 will be described with reference to FIGS. 1 and 2 and FIGS. 4 and 5. As shown in FIG. 2 and FIG. 5, the falling port 6 of the collection gutter 5 and the ball receiving portion 31 of the introduction gutter 20 are in a state of being vertically overlapped. For this reason, the used balls flowing down the collecting gutter 5 fall from the falling port 6 to the ball receiving portion 31, are aligned by the partition wall 24 (32), are guided to the inflow arc gutter 19, and are conveyed to the conveyor belt 12. Is raised by When the falling port 6 and the ball receiving portion 31 overlap each other, the facing right-angled portion 35 of the introduction gutter 20 is almost in contact with the front side surface of the collection gutter 5 and the bottom surface. The falling ball does not leak outside. On the other hand, if it is necessary to replace the conveyor belt 12 of the doffing and conveying machine 10, it is necessary to pull out the entire doffing and conveying machine 10 from one side of the pachinko island stand 1.

Is pulled out, the installation base plate 17 slides on the floor surface and can be easily pulled out (the state shown in FIGS. 1 and 4). When the doffing and feeding machine 10 is stored in the pachinko island stand 1 again after the exchange operation of the conveyor belt 12 is completed, the entire doffing and feeding machine 10 is pushed in to install the base plate 1.
7 is slid to a predetermined position with respect to the floor surface. Then, the facing right-angled portion 35 of the leading end of the introduction gutter 20 is brought into a state of substantially abutting from the front side surface to the bottom surface (a state shown in FIGS. 2 and 5), and the falling port 6 of the collection gutter 5 and the ball receiving portion of the introduction gutter 20. 31 is connected. In this connection state, the connection state is sufficiently firmly and accurately maintained without using any special connection aid. As described above, in the present embodiment, since the ball receiving portion 31 of the introduction gutter 20 is merely inserted below the dropping port 6 of the collection gutter 5, the doffing and feeding machine 10 is taken in and out. In this case, no special connection work or disconnection work is required, and a single worker can perform the work of putting in and out the doffing machine 10 from the side where the doffing machine 10 is taken in and out. In particular, the configuration of the pachinko island stand 1 is not a form in which pachinko machines are lined up in a row, but an island wall type pachinko island stand in which pachinko machines are lined up only on one side (in some cases, the pachinko machines are installed along a wall in a game arcade). In many cases, a passage that allows people to pass between the back side of the pachinko island stand and the wall of the game hall had to be constructed for entering and exiting work of the doffing and conveying machine 10 in the related art. With such a configuration, the pachinko island stand 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 surface of the game arcade can be used effectively. Although the introduction gutter 20 in the doffing and feeding machine 10 according to the embodiment has been described in detail above, in this embodiment, the balls flowing from the left and right collection gutters 5 for collecting used balls are doffed.
