Description

  The present invention relates to a gaming medium conduit for supplying gaming media to gaming media using machines installed on a gaming machine island, and a gaming media replenishment device for replenishing gaming media to gaming media using machines.

  The gaming hall is provided with a gaming machine island in which gaming machines such as slot machines and coin gaming machines are inserted by inserting medals into a predetermined area and arranged side by side. Usually, a medal lending machine is disposed adjacent to the slot machine, and a medal corresponding to the amount of inserted money is paid out. When the medals paid out from the medal lending machine are inserted into the slot machine, the game is started, and as a result of the game, when the symbols of the reels of a plurality of rows become a combination pre-set winning combination, the corresponding number of medals are paid It is a mechanism to be paid as. Therefore, in order to continue the game, it is necessary to sequentially replenish the slot machine with medals for winning and the medal lending machine with medals for lending.

  As means for replenishing medals in response to the request for the medals of such slot machines and medal lending machines, there is a gaming medium circulation system for replenishing and recovering medals inside the gaming machine island. As an example of the game medium circulation system, the medal distributed on the line constituted by the belt conveyor is dropped to the supply chute by the medal distribution device provided on the line, and the medal in the supply chute is connected to the supply chute After passing through the above-mentioned piping, there are some which supply a medal to a slot machine or a medal lending machine via a bellows pipe connected to the piping.

  By the way, when such a game medium circulation system is installed on a game machine island, work may be performed to connect piping to a bellows pipe previously connected to a slot machine or a token lending machine. In this case, work to connect the piping to this bellows tube must be performed in a narrow space set back and surrounded by various equipment in the gaming machine island, for example, screwing-in type fixing and screw fixing using hooks, etc. which are generally performed. It is extremely difficult to perform the method in such a space, and the installation work is difficult.

  Therefore, as a method of connecting the pipe to the bellows pipe, it is a game medium passage formed by connecting the supply pipe which is the bellows pipe and the pachinko ball introduction passage into which the supply pipe is inserted, and connection prepared separately DESCRIPTION OF RELATED ART The structure which protrudes the protrusion part of a member in a pachinko ball introduction passage, protrudes on the supply pipe side, contacts a supply pipe, and supports a supply pipe is known (patent document 1). The connecting member presses the projection against the supply pipe by the elastic deformation of the connection member itself in a state where the projection is moved in the direction away from the supply pipe from the state where the supply pipe and the pachinko ball introduction passage are connected. Apply a biasing force in the direction to hold the connection.

  The structure described in Patent Document 1 has a structure in which the connecting member penetrates the pachinko ball introduction passage and protrudes toward the supply pipe to support the supply pipe and connects the supply pipe and the pachinko ball introduction passage. It can be done easily and in a short time.

  However, in the case described in Patent Document 1, the connecting member continues to apply an urging force in the direction of pressing the protrusion against the supply pipe by the elastic deformation of the connection member itself, thereby connecting the supply pipe and the pachinko ball introduction passage. Because of the structure to hold, there is a possibility that the biasing force is reduced due to the reduction of the elastic deformation of the connecting member, and the connection reliability is reduced.

  In addition, after the process of inserting the supply pipe into the pachinko ball introduction passage in the installation work, the process of penetrating the connecting member into the pachinko ball introduction passage and projecting to the supply pipe side is required, and the number of processes at the installation site is large. . In addition, the process of penetrating the connecting member into the pachinko ball introduction passage and projecting to the supply pipe side requires work near the joint of both pipes, so the space around the joint is surrounded by various equipment and is a narrow space When it had to be carried out, the workability was extremely bad and there was a risk that the installation work would be difficult.

  The present invention has been made under the circumstances described above, and its object is to provide a gaming medium conduit and gaming medium supply device capable of easily connecting piping and a bellows tube and having high connection reliability. It is.

  In order to solve the above-mentioned subject, the game medium pipeline concerning the present invention inserts the bellows pipe by which a mountain part and a valley part were provided alternately under the piping which a game medium falls and passes through. The pipe is provided so as to project from the outer peripheral side of the pipe from at least two openings formed by penetrating the peripheral wall of the pipe, and the lower open end of the opening. A convex portion to be formed and a horizontal surface formed on a side surface on the upper side of the convex portion, and an end portion protruding through the opening to the inner peripheral side of the pipe, and the protruding end portion is the above And a flat elastic member supporting at least the valley portion of the bellows tube to support the bellows tube, wherein the elastic member is allowed to be elastically deformed upward by a space given by the opening, and the bellows When inserting a tube, it can be elastically deformed upward to allow passage through the ridge of the bellows tube It is formed, characterized in that (claim 1).

  By this configuration, the elastic member is allowed to elastically deform upward due to the space provided by the opening. Therefore, when the bellows tube is inserted into the pipe and pushed in, the force in the direction to push the elastic member upward from the peak of the bellows tube under the elastic member is applied, and the elastic member is elastically deformed upward and the elastic member You can pass the mountain to the upper side of the For this reason, if an elastic member is attached to piping before construction, it can be connected only by inserting and pushing in a bellows tube in piping in installation work.

  In addition, although the elastic member is allowed to be elastically deformed upward by the space provided by the opening, it can not be elastically deformed downward because no space is given to the lower side, or it is elastically deformed significantly. I can not Therefore, when trying to pull out the bellows tube from inside the pipe, a force in the direction to push the elastic member downward is applied from the peak of the bellows tube on the upper side of the elastic member, but the elastic member does not elastically deform downward or Since it can not be elastically deformed to such an extent that it passes through the peak part of the bellows tube, the peak part can not pass below the elastic member. For this reason, it is possible to prevent the bellows tube from coming off from the piping.

  In this case, the convex portion has a vertical surface formed in a direction orthogonal to the horizontal surface from the end of the horizontal surface, and the elastic member is a flat plate piece disposed on the horizontal surface of the convex portion and an end of the flat plate piece The elastic member preferably includes a fixing piece bent in an orthogonal manner from a portion, and the elastic member is fixed by screwing the fixing piece of the elastic member to the vertical surface of the convex portion (claim 2).

  With this configuration, the elastic member is fixed by screwing the fixing piece to the vertical surface of the convex portion, so that the flat plate of the elastic member can easily generate a desired elastic force.

  In this case, the pipe is formed with a flange on the inner peripheral side above the opening, and the flange is in contact with the end of the bellows pipe to restrict insertion of the bellows pipe (Claim 3).

  With this configuration, the operator does not have to consider the length of the bellows tube to be inserted at the work site, since the flange portion contacts the end of the bellows tube to restrict excessive insertion of the bellows tube. Therefore, the bellows tube can be more easily connected to the piping.

  In this case, a plurality of the elastic members are disposed, and the one elastic member and the other elastic member are disposed at vertically offset positions, and the respective end portions of at least the different valleys of the bellows tube are at least It is better to contact and support the bellows tube (claim 4).

  By this configuration, the end portions of one elastic member and the other elastic member can be brought into contact with different valleys of the bellows tube, and the plurality of elastic members can be brought into contact with one valley and the one valley Can prevent concentration of peaks and valleys. For this reason, it is possible to prevent the bellows tube from falling off due to the spread of the mountain and the valley, and to improve the connection reliability.

  In this case, it is preferable that the elastic member has an end portion projecting to the inner peripheral side of the pipe formed in an arc shape along the valley portion of the bellows pipe (claim 5).

  With this configuration, when the elastic member contacts the bellows tube, the arc-shaped end can contact the outer peripheral surface of the valley of the bellows tube in surface contact or line contact to support the bellows tube. Therefore, the elastic member can stably support the bellows tube and can improve the connection reliability. Further, when the elastic member is inserted into the valley portion of the bellows tube and enters the inner peripheral side of the bellows tube, it is possible to prevent the passage of the game medium from being hindered.

  The gaming media replenishment apparatus according to the present invention is a gaming media replenishment apparatus for replenishing gaming media to a plurality of gaming media using machines arranged in an array, and the gaming media pipeline according to any one of claims 1 to 5. The game medium is supplied to the game medium using machine via the game machine (claim 6).

  According to the gaming medium channel of the present invention, the pipe is configured as described above and can be connected simply by inserting and pushing the bellows pipe into the pipe in the installation operation, so the pipe and the bellows pipe can be easily connected. be able to. In addition, since the bellows tube can be prevented from coming off from the piping, connection reliability can be enhanced.

As described above, six flapper units 17 are attached, and there are a total of 12 distribution positions of 6 on the right side and 6 on the left side of the transport belt 11, and the discharge ports 18a are provided in each of the positions.

  The medals distributed by the flapper unit 17 and passing through the discharge port 18a of the cover unit 18 are dropped and received by the replenishment chute 20, and then dropped and passed through the gaming medium channel formed at the lower part of the replenishment chute 20 It is transported to the slot machine 2 or the medal lending machine 3. Next, a game medium channel according to the present invention will be described.

  As shown in FIG. 4, the gaming medium conduit according to the present invention is, as shown in FIG. 4, a pipe 30 through which a medal falls and passes, a bellows pipe 40 inserted into the lower part of the pipe 30, and an elastic member supporting the bellows pipe 40. And 50 are mainly composed.

  In the present embodiment, as shown in FIG. 6, the pipe 30 is integrally formed with the supply chute 20. The supply chute 20 is detachably formed on the lower surface of the upper chute 21 and the lower surface of the upper chute 21 having an intake port 21a for taking in the medal into which the medal passing through the discharge port 18a of the cover unit 18 is incorporated. The lower chute 22 is formed on the lower surface and has a circular outlet 22a (see FIG. 9), which is formed and gradually narrows the inside toward the lower side and the medal taken in is dropped and discharged, and the light emitting portion A medal detection sensor 23 mainly configured to detect the presence or absence of a medal blocking the light beam according to whether or not the light receiving unit receives the transmitted light beam.

  As shown in FIGS. 6 and 9, the pipe 30 is a cylindrical resin body having a substantially circular cross section and extends downward from the discharge port 22 a formed in the lower part of the supply chute 20. It is integrally formed. As shown in FIGS. 8 (a), 8 (b) and 9, a flange portion 35 is formed on the inner peripheral side near the upper end of the pipe 30. The flange portion 35 can be in contact with the upper end portion of the inserted bellows tube 40 to restrict excessive insertion of the bellows tube 40.

  As shown in FIGS. 6, 7 (a) and 9, rectangular openings 31 and 32 formed through the peripheral wall of the pipe 30 are formed below the flange 35 of the pipe 30. . Two openings 31 and 32 are arranged at positions 180 degrees apart from each other about the axis of the pipe 30. In addition, the opening 31 and the opening 32 are disposed at vertically offset positions. In this case, the opening 32 formed in the right direction is formed at a position shifted upward.

  And as shown to FIGS. 6-10, the rectangular-shaped convex part 33,34 is protrudingly provided in the outer peripheral side of the piping 30 from the opening end part of the lower side of the opening parts 31 and 32. As shown in FIG. Horizontal surfaces 33a and 34a are formed on the upper side surfaces of the convex portions 33 and 34 from the outer peripheral upper end of the convex portions 33 and 34 to the inner peripheral side of the pipe 30, and horizontal surfaces 33a and 34a from the outer peripheral end portions of the horizontal surfaces 33a and 34a Vertical surfaces 33b and 34b are formed in the direction orthogonal to 34a.

  As shown in FIG. 6, the elastic member 50 is formed by bending a flat plate made of stainless steel, and the flat plate piece 50a disposed on the horizontal surfaces 33a and 34a of the convex portions 33 and 34 and an end portion of the flat plate piece 50a. And a fixed piece 50b which is bent in an orthogonal manner. In the present embodiment, a stainless steel material is used as the material of the elastic member 50, but another metal may be used as long as it has elasticity. In addition, as long as it has elasticity, it does not need to be metal, and may be, for example, resin material. In this respect, as shown in FIG. 10, it is a material capable of being elastically deformed so as to be bent upward when a force in the direction of pushing up from the lower side is applied to the projecting end of the flat plate piece 50a. Any material may be used as long as it does not cause breakage such as elastic deformation or cracking which is large enough to allow the mountain portion 40a of the bellows tube 40 to pass when a force is applied.

  As shown in FIG. 10, the flat plate piece 50 a of the elastic member 50 penetrates the opening 31 and protrudes an end to the inner peripheral side of the pipe 30. In the present invention, the projecting end of the flat plate piece 50a supports the bellows tube 40 at least in contact with the valley portion 40b of the bellows tube 40 with respect to the degree of protrusion of the end to the inner peripheral side of the pipe 30; In addition, when the bellows tube 40 is inserted, the flat plate piece 50a may be elastically deformed to the upper side so that the protrusion of the bellows tube 40 can pass through. In this regard, “at least in contact” may be such that the projecting end merely contacts the valley 40 b of the bellows tube 40, or the projecting end engages the valley 40 b of the bellows tube 40. It means that it may be inserted, inserted into the inner peripheral side of the bellows tube 40, and the like.

  In this respect, in the present embodiment, as described later, the bellows tube 40 is formed by spirally winding a metal wire, and adjacent metal wires are not adhered to each other. Therefore, the end of the flat plate piece 50a can be inserted between the metal wires and enter the inner peripheral side of the bellows tube 40 (see FIG. 13). Therefore, with regard to the degree of protrusion of the end of the flat plate 50a to the inner peripheral side of the pipe 30 in the present embodiment, the protruding end is inserted into the valley portion 40b of the bellows tube 40 and the inner periphery of the bellows tube 40 is obtained. It penetrates and protrudes to support the bellows tube 40. Specifically, as shown in FIG. 8 (b), it protrudes slightly beyond the outer peripheral line (shown by Z in FIG. 8 (b)) of the valley portion 40b of the bellows tube 40.

  Further, the flat plate piece 50 a is formed in an arc shape in which an end projecting to the inner peripheral side of the pipe 30 is along the outer peripheral surface of the valley portion 40 b of the bellows tube 40. With such a configuration, it is possible to prevent the flat plate piece 50a from being inserted into the valley portion 40b of the bellows tube 40 and entering the inner peripheral side of the bellows tube 40, thereby preventing the passage of the medals.

  The bellows tube 40 is a metal tube formed by spirally winding a metal wire having a substantially circular cross section, as shown in FIGS. As shown in FIG. 10, on the peripheral wall of the bellows tube 40, the semicircular outer periphery of the metal wire forms a peak portion 40a, and a valley portion 40b is formed between the peak portions 40a of the metal wire continuously stacked vertically. Is formed, and the mountain portion 40a and the valley portion 40b are alternately provided. One end of the bellows tube 40 is connected to the slot machine 2 or the medal lending machine 3, and the other end stands in the vicinity of the supply line 10 with the open end upward. In the present invention, the bellows tube 40 may be a tubular tube in which the peak portions 40a and the valley portions 40b are alternately provided. For example, various types of resin such as vinyl chloride, elastomer, etc. or various foamed resins It may be

  Next, the connection procedure of the bellows tube 40 to the piping 30 will be described. In this case, the replenishment line 10 shown in FIG. 5 is assembled outside the gaming machine island, and placed from the upper side in the vicinity of the center of the gaming machine island inside back-to-back between the slot machine 2 and the token lending machine 3. Or when connecting the supply chute 20 and the supply line 10 while connecting the supply chute 20 and the supply line 10 while installing the game medium supply device 4 while connecting the other end of the bellows pipe 40 whose one end is connected to the medal lending machine 3 and the pipe 30 having the supply chute 20 Will be explained.

  First, the worker fixes the elastic member 50 to the pipe 30 outside the gaming machine island. In this case, the flat plate piece 50a of the elastic member 50 is placed on the horizontal surface 34a of the convex portion 34 of the pipe 30 integrated with the supply chute 20, and the fixing piece 50b of the elastic member 50 is mounted on the vertical surface 34b of the convex portion 34. It joins and it screws and fixes with the screw | thread 55 from the outer side of the fixing piece 50b (refer FIG. 6). Thereby, since the elastic member 50 is screwed and fixed to the vertical surface 34b of the convex portion 33 of the pipe 30, the flat plate 50a of the elastic member 50 is configured to easily generate a desired elastic force. be able to. As shown in FIG. 6, in the present embodiment, another elastic member 50 is attached to the convex portion 33 in the same manner as described above.

  Next, the worker inserts the bellows tube 40 standing upright with the open end in the vicinity of the supply line 10 in the lower opening of the pipe 30 (see FIG. 4). When the worker inserts the bellows pipe 40 into the pipe 30, as shown in FIGS. 9 and 10, the bellows section 40 continues until the first peak portion 40a at the uppermost side of the bellows pipe 40 contacts the end of the flat piece 50a. The pipe 40 can be pushed without resistance, but when the peak portion 40a comes in contact with the end of the flat piece 50a, there is resistance and it can not be pushed. In this case, the flat plate piece 50a of the elastic member 50 is allowed to be elastically deformed such that the end is bent upward by the space given by the opening 31 as shown by an imaginary line in FIG. For this reason, when the bellows tube 40 is further pushed into the pipe 30, a force in a direction to push the flat plate piece 50a upward is applied from the mountain portion 40a of the bellows tube 40 located below the flat plate piece 50a. It can be elastically deformed to allow the mountain portion 40a to pass above the flat plate piece 50a.

  More specifically, as shown in FIG. 11A, the operator inserts the bellows pipe 40 into the pipe 30 to make the first peak portion 40a on the uppermost side of the bellows pipe 40 a flat piece 50a of the elastic member 50. Contact with the end of the Next, as shown in FIG. 11B, the worker applies a force to push down the pipe 30 from the upper side (force in a direction to push the elastic member 50 upward), and bends the end of the flat plate piece 50a to the upper side Elastically deform. Next, as shown in FIG. 11C, the worker further applies a force to push down the pipe 30 from the upper side (a force in a direction to push the elastic member 50 upward), and the mountain is raised above the flat plate 50a of the elastic member 50. The part 40a can be passed. Next, the worker passes the mountain portions 40a of the plurality of bellows tubes 40 to the upper side of the flat plate piece 50a of the elastic member 50 in the same manner as in FIGS. 11 (a) to 11 (c).

  As shown in FIG. 12, when the worker passes the plurality of mountain portions 40 a of the bellows tube 40 to the upper side of the flat plate piece 50 a of the elastic member 50, it is formed on the inner peripheral side above the opening 31 of the pipe 30. The flange portion 35 contacts the upper end portion of the bellows tube 40 to restrict excessive insertion of the bellows tube 40. In this manner, the operator does not have to consider the length of the bellows tube 40 to be inserted at the work site since the flange portion 35 contacts the end of the bellows tube 40 and restricts the insertion of the bellows tube 40. The bellows pipe 40 can be easily connected to the pipe 30.

  The connection work of the bellows pipe 40 to the piping 30 is completed above. The worker connects the supply chute 20 connected to the pipe 30 to the supply line 10 (see FIG. 4) and continues the installation work of the gaming medium supply device 4.

  As shown in FIGS. 12 and 13, when the operator completes the connection of the bellows pipe 40 to the pipe 30, and the gaming medium channel is completed, the projecting end of the flat plate piece 50a of the elastic member 50 is the bellows pipe. It is inserted into a valley portion 40 b of 40 and enters the inner peripheral side of the bellows tube 40 to support the bellows tube 40. In this case, although the flat piece 50a of the elastic member 50 is allowed to be elastically deformed on the upper side by the space given by the openings 31, 32, it is possible to elastically deform to the lower side because no space is given on the lower side. It can not or can not be elastically deformed greatly. Therefore, when trying to pull out the bellows tube 40 from inside the pipe 30, a force in the direction to push the flat plate piece 50a downward is applied from the peak portion 40a of the bellows tube 40 located above the flat plate piece 50a. It can not be elastically deformed to the side, or it can not be elastically deformed to a large extent to allow the peak portion 40a of the bellows tube 40 to pass, so the peak portion 40a can not pass below the flat plate piece 50a. Therefore, the bellows tube 40 can be prevented from coming off from the piping 30, and connection reliability can be enhanced.

  Further, as shown in FIGS. 12 and 13, in the present embodiment, two elastic members 50 are disposed at positions separated by 180 degrees with respect to the axis of the pipe 30, and one elastic member 50 and the other elastic member 50 are The respective ends are inserted into different valleys 40 b of the bellows tube 40 and enter the inner peripheral side of the bellows tube 40 to support the bellows tube 40. Thereby, one elastic member 50 and the other elastic member 50 can be brought into contact with different valleys 40b of the bellows tube 40, and the two elastic members 50 come in contact with one valley 40b and force is generated in one valley 40b. It is possible to prevent the mountain portion 40a and the valley portion 40b from spreading. Therefore, it is possible to prevent the bellows tube 40 from coming off due to the spread of the mountain portion 40a and the valley portion 40b, and it is possible to improve the connection reliability.

  Further, when the worker completes the connection of the bellows pipe 40 to the pipe 30 and the gaming medium channel is completed, the end of the flat plate piece 50a is inserted into the valley portion 40b of the bellows pipe 40 and the inside of the bellows pipe 40 is completed. It enters into the circumferential side and supports the bellows tube 40, but since the end of the flat plate piece 50a is formed in an arc shape along the valley portion 40b of the bellows tube 40, it prevents the passage of medals from being obstructed. be able to.

  As described above, according to the gaming medium pipe line of the present invention, the bellows pipe 40 can be connected to the pipe 30 only by inserting and pushing the bellows pipe 40 into the pipe 30 in the installation operation. Can be easily connected. In addition, since the bellows tube 40 can be prevented from coming off from the piping 30, connection reliability can be enhanced.

  In the embodiment described above, the end of the flat plate 50a of the elastic member 50 that protrudes to the inner peripheral side of the pipe 30 is inserted into the valley portion 40b of the bellows tube 40 and enters the inner periphery of the bellows tube 40 Although the bellows tube 40 is supported, in the present invention, the projecting end may support at least the valley portion 40 b of the bellows tube 40 to support the bellows tube 40. For example, the projecting end may simply contact the valleys 40 b of the bellows tube 40 to support the bellows tube 40. Even with this configuration, the same effect as that of the above embodiment can be obtained.

  In the embodiment described above, although two elastic members 50 are disposed in the pipe 30, a plurality, for example, three may be provided. In this case, the three elastic members 50 may be disposed at positions 120 degrees apart from each other about the axis of the pipe 30, and the three elastic members 50 may be disposed at positions displaced in the vertical direction. According to this structure, the connection reliability can be improved more than the embodiment described above.
