BACKGROUND OF THE INVENTION
The present invention relates to a medal lifting lift for lifting medals to a storage tank on an upper part of a gaming machine installation island in order to distribute medals to gaming machines.
[0002]
[Prior art]
Used medals and payout medals collected from gaming machines such as slot machines are contaminated by adhesion of human hand grease, cigarette dust, etc., and are cleaned and cleaned by a medal polishing device. The medals after polishing and cleaning are transported to a storage tank on the upper part of the gaming machine installation island by a medal lifting lift and then delivered to each gaming machine. As a medal lift, for example, Japanese Patent Application Laid-Open No. 2001-229429 discloses an endless belt stretched in the vertical direction and a large number of buckets arranged as conveying blades. However, if the bucket has a fixed width, the medals flow down toward the opening end on one side, and the medals are suspended from the shelf and are not discharged smoothly from the opening end. There was a problem.

JP 2001-229429 A (FIG. 5)
[0004]
Therefore, a bucket having a first opening shape toward the opening end from which medals are discharged was invented, and this was filed earlier as Japanese Patent Application No. 2002-246380. That is, the bucket in this application is as shown in FIGS. 7 and 8, and the bucket 15 includes a bottom plate 152 that is inclined downward toward the opening end 151 on one side and side walls 153 on both sides thereof. The bottom plate 152 is slightly widened from the upstream side toward the opening end 151. Since one side wall 153 of the bucket 15 is attached to the toothed belt 2, and the bucket 15 is housed in the frame 16 so that the front and rear ends thereof are in sliding contact with the side wall 161, the bucket 15 After the inserted medal is lifted upward, the medal can be smoothly discharged from the discharge port provided in the side wall 161.
[0005]
However, the opening end 151 of the bottom plate 152 of the bucket 15 is cut in a straight line, and the side wall 161 slidably in contact with the opening end 151 is also flat. There may be a gap between the side wall 161 and the side wall 161. Since the medal is thin, if such a gap is generated, the medal falls from the gap and accumulates at the lower part of the lift, which causes a problem in the lifting of the medal.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 4 is a diagram showing a medal polishing / lifting device, where 1 is a medal polishing device and 10 is a medal lifting lift. The medals collected from the gaming machine and the counting device are polished and cleaned in the polishing apparatus 1 and then sent to the lifting lift 10 and transferred to the medal storage tank 20 on the upper part of the island. Then, medals are supplied to the medal distribution vehicle M via the medal supply device 30 provided in the medal storage tank 20 as shown in FIG. 5, and the medal supply vehicle M delivers the medals to each gaming machine.
[0009]
Of the medals lifted by the lift 10 and sent to the medal storage tank 20, the surplus medals overflowing from the medal storage tank 20 are stored in the surplus medal storage tank 21. Then, the medals stored in the surplus medal storage tank 21 are reintroduced into the bucket 15 of the lifting lift 10 via the return device 40 as necessary.
[0010]
As shown in FIG. 6, the lifting lift 10 includes an upper driving pulley 12 driven by a motor 11, a lower driven pulley 13, and a toothed belt 14 wound around the driving pulley 12 and the driven pulley 13. And a large number of buckets 15 attached to the toothed belt 14. On the upper part of the substantially U-shaped frame 16 to which the drive pulley 12 and the driven pulley 13 are attached, a discharge rod 17 for introducing medals into the medal storage tank 20 is provided.
[0011]
As shown in FIGS. 1 and 2, each bucket 15 has a front-opening shape in which the bottom plate 152 is slightly widened toward the opening end 151 on one side from which medals are dropped and discharged, thereby eliminating the shelf of medals. Is surely discharged. A plurality of projecting pieces 154 are formed in a sawtooth shape at the opening end 151 of the bottom plate 152 of the bucket 15, but the interval between the adjacent projecting pieces 154 is smaller than the medal diameter. On the other hand, on the side wall 161 of the frame 16 with which the open end 151 is slidably contacted, a plurality of concave groove portions 162 are fitted side by side in parallel with the saw-toothed projecting pieces 154 and fitted with the projecting pieces 154. Yes. Since the medal flows down toward the opening end 151, the rear end opening 155 of the bucket and the side wall 163 slidably contacting the rear end opening 155 may be formed in a straight line or a flat shape as usual. . Of course, it is also possible to make the same uneven shape as the tip side.
[0012]
As described above, the sawtooth-shaped projecting piece 154 is formed on the bottom plate 152 of the opening end 151 of the bucket 15 from which the medals are discharged, and the concave groove 162 into which the projecting piece 154 is fitted is formed on the side wall 161 of the frame 16. Even when the bucket 15 vibrates somewhat, the bucket 15 moves upward in a state where the protruding piece 154 bites into the concave groove 162. Therefore, as shown in FIG. 3, the protrusion 154 biting into the concave groove 162 can reliably prevent the medal from dropping downward.
[0013]
In the lift 10 configured as described above, medals polished and cleaned by the polishing apparatus 1 are inserted into the bucket 15 from the lower medal insertion slot 18 through the insertion rod 181. The medals thrown into the bucket 15 are lifted up to the upper medal storage tank 20, but sawtooth-shaped protrusions 154 provided on the bottom plate 152 of the bucket 15 bite into the concave grooves 162 provided on the side wall 161 of the frame 16. Therefore, even if the toothed belt 2 vibrates during the transportation, the medal does not come out from the opening end 151 and falls.
[0014]
The raised medals are dropped and discharged when the opening end 151 of the bucket 15 reaches the opening of the discharge rod 17 to the medal storage tank 20, but the bucket 15 is widened in a front-opening manner, It will be discharged | emitted at a stretch from the opening end 151, without raising. Then, medals are supplied from the storage tank 20 to the medal distribution vehicle M via the medal supply device 30, and the medal supply vehicle M delivers the medals to each gaming machine. The bucket 15 that has finished being lifted is turned upside down at the drive pulley 12 and lowered.
[0015]
FIG. 9 shows a bucket 15 of the second embodiment. On one side 153a of the bucket 15 which is the outer side during the lifting, a protrusion 156 extending in the lifting direction (longitudinal direction) is formed. As shown in FIGS. 10 to 12, a guide member 50 in which a concave groove 51 corresponding to the protrusion 156 is formed is disposed immediately below the medal slot 18 at the lower part of the medal lifting lift 10. The protruding portion 156 is fitted into the concave groove 51, and the bucket 15 slides. Here, the widths of the protrusions 156 and the groove 51 are smaller than the diameter of the medal, and it is impossible to slip through the groove 51 of the medal. Further, the tip of the bottom surface 182 of the medal slot 181 is attached to the upper end of the guide member 50 without forming a gap. Therefore, even when the bucket 15 is shaken by vibration or the like, the side wall 153a of the bucket 15 and the guide member 50 are engaged with each other by the protrusion 156 and the groove 51, so that the medal falls downward from the gap therebetween. There is nothing.
[0016]
Here, since the bottom plate 152 of the bucket 15 is curved in a concave shape as shown in FIG. 13 (d), the contact portion between the medal and the bottom plate 152 is reduced, the frictional resistance is reduced, and the medal is easily made. Can flow down.
In the above-described embodiment, the lifting lift 10 is for lifting the polished medal to the storage tank 20 on the upper part of the island, but the present invention is a lifting lift for lifting the medal before polishing. Needless to say, it can also be applied.
[0017]
【The invention's effect】
As described above, the medal lifting lift of the present invention has a sawtooth-like projecting piece formed at the medal discharge opening end of the bucket bottom plate, and a plurality of concave grooves having a shape corresponding to the projecting piece are formed on the frame side wall. Since this is provided and the projecting piece is bitten into the concave groove, even if the bucket vibrates during the feeding, the medal does not come out from the gap between the opening end and the frame side wall and falls.
In addition, a ridge that extends in the lifting direction is formed on one side of the bucket, and a guide member having a concave groove portion into which the ridge can be fitted is disposed immediately below the medal insertion slot. The medal does not fall from the gap between the mouth and the bucket side wall. Furthermore, since the bottom plate of the bucket is curved in a concave shape, medals can be easily discharged.
Therefore, this invention has a big advantage as what can lift a medal to the medal storage tank of the island upper part reliably.
