Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a medal carry-in device of a medal collection lifter for circulating and supplying medals of a large number of slot machines provided in a pachinko parlor or the like.

<Prior art> Generally, as a means for supplying and collecting circulation of medals used in a large number of slot machines provided at amusement centers such as pachinko parlors, the medal collection that is discharged from each slot machine is used as a belt conveyor. A circulation supply system that is transferred to a medal collection lifter placed on the device and installed at the island edge, etc., after pumping the medals accumulated in the lower part of this medal collection lifter to the upper position, and then again delivering the medals to each slot machine with a separate supply mechanism. Is taking. In this case, the medal carry-in device that faces the end of the medal collection lifter uses a simple belt conveyor, and its rotation is always forward, and the placed medals are simply continuously transferred.

<Problems to be solved by the invention> However, in this way, with the use of the belt conveyor of the normal rotation at all times, even if the bucket of the medal recovery lifter waiting (fall filling) is full and overflows, the medal recovery is continued. In some cases, the overflowing medals during the pumping operation tend to be clogged between the bucket and the machine frame, leading to a failure such as a lifter stop, which sometimes necessitates an inspection of the carry-in amount in the medal lifter, which is a troublesome work.

In view of the above situation, the present invention provides a medal carry-in device for a medal collection lifter that solves the above problem by reversing the belt conveyor for carrying in medals when the bucket part of the medal collection lifter is full. It is intended.

<Means for Solving the Problems> The present invention has a bucket attached to one side of an elevator-type bucket type medal collection lifter, and is equipped with a medal amount detection sensor at a side position of a standby position below the bucket. The belt conveyor for the collected medals installed in the previous stage facing the bucket at the standby position of the collection lifter is made reversible by the reversible drive motor that rotates in reverse due to the upper limit amount detection of the medal amount detection sensor, and drops into the bucket. Is to be stopped instantly.

<Operation> Due to the above-described configuration, the medals discharged from the appropriately arranged slot machines are carried on the belt conveyor below and returned to the medal collection lifter side. At this time, if the bucket for waiting for the medal collection lifter to fall is full,
The upper limit amount is detected by the medal amount detection sensor provided on this side portion, and the detection signal is used as the control signal of the drive motor of the belt conveyor, in order to convert the reversible motor of the belt conveyor from forward rotation to reverse rotation, The medals on the belt conveyor are immediately moved backward, and the dropping into the bucket is stopped instantly, and there is no further accumulation of medals in the bucket, and the bucket can be smoothly pumped up.

<Embodiment> The present invention will be described below with reference to the drawings of the embodiment.

Reference numeral 1 is a tower-shaped casing 2 that serves as a machine frame. An endless chain 4 is hung on upper and lower sprockets 3 and 3 and a single bucket 5 is attached to the carrier side, which is one side, and the bucket 5 is moved up and down. In the elevator type bucket-type medal collection lifter, a belt chute 8 having a reversible drive motor 7 attached thereto is installed on a guide chute 6 projecting outside the bucket 5 at the drop standby position which is the lower part of the bucket. Bucket 5
A medal amount detection sensor 10 is attached to a side position of the medal loading device 9 as a whole. In this case, the medal amount detection sensor 10 is guided to the control means 11, communicates with the drive motor 7 connected to the control means 11, and controls the rotation direction of the drive motor 7.

To explain this effect, first, a support frame (not shown) such as a gutter frame installed below the slot machine 12 having a large number of arrays.
A belt conveyor 8 is laid on the belt conveyor 8. The medals A discharged from the slot machine 12 are placed on the belt conveyor 8 and transferred to the front side of the medal collection lifter 1.

Here, the medals A carried in and dropped from the end of the belt conveyor 8 sequentially flow through the guide chute 6 and into the bucket 5 at the lower standby position.

In this case, when this bucket 5 is filled with a predetermined amount (upper limit amount) of medals A, this medal inflow amount is detected by the medal amount detection sensor 10 arranged on the side portion, and this detection signal is appropriately controlled. 11, the rotation switching control signal is input to the drive motor 7 of the belt conveyor 8, and the rotation of the drive motor 7 is reversely rotated to retract the mounted medal A.
The dropping of the medal A to the bucket side is temporarily stopped. The fall stop time from this belt conveyor 8 is
The retreat width (constant length) of the belt conveyor 8 itself or the reverse rotation time may be appropriately determined.

When the bucket 5 is thus filled with a predetermined amount of medals A and the lift motor 13 is driven, the bucket 5 integral with the chain 4 is lifted and stopped at the upper limit position, and the opening formed at the lower end of the inclined bottom of the bucket 5 is opened. The medal A jammed from a portion (not shown) is slid to the supply path side and dropped. After this, the emptied bucket 5 is an elevator mechanism, so it immediately descends from its position and returns to the standby position. In this case, since there is no large amount of medal filling that overflows when the bucket 5 is lifted and transported, the buckets are smoothly transported without causing clogging of medals between the housings 2, and the tanks are replenished to the tank through the upper drop port of each slot machine. The medals A are circulated and fed to the feeding belt 12 (not shown).

<Effects of the Invention> As described above, the medal carry-in device for the medal collection lifter of the present invention has the structure in which the belt conveyor facing the lower end of the bucket type medal collection lifter is configured to be reversely rotatable, so that the standby position of the medal collection lifter can be improved. The medal amount detection sensor on the side detects that a predetermined amount of medals will enter the bucket,
Due to this, since the belt conveyor is immediately rotated in the reverse direction, there is no unnecessary drop of medals in the bucket, and the medals do not overflow and do not cause a malfunction in the upward movement of the bucket, Smooth elevator transportation is possible. In addition, since the mechanism is simple by simply reversing the belt conveyor, it is easy to install and improve the conventional device, and the medal collecting lifter is easily maintained.
