DESCRIPTION OF THE PREFERRED EMBODIMENTS A lift device according to an embodiment of the present invention will be described below with reference to the accompanying drawings. This lift device is a coin (coin) collected from each ball rental machine of a pachinko machine.
To the money changer installed at the end of the “island”. The coins inserted into each ball lending machine are conveyed to the vicinity of the money changer by the conveyor provided on the back side of the pachinko machine.
At that time, since the money changer is at a considerably high position with respect to the conveyor, the collected coins are lifted up by the lift device and guided into the money changer.

FIG. 1 is a side view of the lift device, and FIG. 2 is a partial rear view of its lower portion. As shown in both figures, the lift device 1 includes a pair of left and right guide members 2 and 2 each having a vertically long track shape, and a plurality of vertically guided circular members that are guided by the pair of guide members 2 and 2. Each of the buckets 3, a lift member 4 that pushes up the plurality of buckets 3 one by one, and a drive device 5 that operates the lift members 4.

The coin C collected by the conveyor is
The coins are randomly transferred from the lower coin introduction port 6 to the bucket 3, and are lifted upward along the guide member 2 by the lift member 4 and fed into the upper coin delivery port 7 connected to the money changer.

As shown in FIG. 3, each guide member 2 has an arc-shaped upper guide portion 11 and a lower guide portion 12, and an upward guide portion 13 and a downward guide portion 1 which extend vertically in a straight line.
4 and has a track shape, that is, an annular shape. Each of the guide members 2 has a guide groove (guide portion) 2a inside which is bent in a U-shaped cross section, and the left and right guide members 2 and 2 have their guide grooves 2a and 2a mutually separated. The buckets 3 are combined so as to face each other with a gap between which the bucket 3 is sandwiched. In this case, the coin introducing port 6 is provided in front of the rising guide portion 13 of the guide member 2 in between.
A coin outlet 7 is provided at the rear, and the lower guide portion 1
The bucket 3 which has moved around 2 and started to rise, faces the coin inlet 6, further rises, and faces the coin outlet 7 in front of the upper guide portion 11.

Each of the buckets 3 is guided by the left and right guide members 2 on both sides to circulate, and repeatedly rises and falls. As shown in FIG. 4, each bucket 3 has a pair of left and right side plates 21,
21 and a bottom plate 22 passed between the side plates 21 and 21, so that the bottom plate 22 can slide down the coin C by its own weight.
It has a downward slope from the front to the rear. That is, the front surface and the rear surface of the bucket 3 are open, the coin C is received from the front and the coin C is sent from the rear. In this case, the rising guide portion 1 of the guide member 2 is prevented so that the coin C being conveyed does not slip off the bottom plate 22.
A coin receiving plate 8 is attached to 3 along with it. The coin receiving plate 8 includes the left and right guide members 2, 2
The coin C has a width between the coin introduction port 6 and a length from a position slightly below the coin introduction port 6 to the coin delivery port 7. When the coin is held so that it does not slip off from the coin 3, and is conveyed to the coin outlet 7, the coin is removed from the upper end of the coin receiving plate 8 and slides down from the bucket 3 toward the coin outlet 7.

On the other hand, on the outer surface of each side plate 21, a pair of moving direction guide rollers 23, 23 lined up in the moving direction, and a width direction guide roller 24 orthogonal to the moving direction guide rollers 23 are provided.
, And is rotatably mounted. The pair of moving direction guide rollers 23, 23 are respectively loosely inserted into the guide grooves 2a of the respective guide members 2, guide the movement of the bucket 3, and hold the posture of the bucket 3 during movement. The width-direction guide roller 24 rolls on the groove bottom of the guide groove 2a to prevent the bucket 3 from moving eccentrically with respect to the left and right guide members 2, 2, and the shaft portion of each moving-direction guide roller 23 is , To prevent sliding contact with the groove bottom of the guide groove 2a.

Further, a small protrusion 26 extending downward is provided on the outer surface of the lower end portion of each side plate 21, and when the bucket 3 rises, an inside of the small protrusion 26 is an upper end of the lower bucket 3. The part is designed to fit in. That is,
The buckets 3 in the ascending process are engaged with each other so as to be inserted into each other, and are arranged in the vertical direction without forming a gap.

The lift member 4 is disposed inside the lower guide portion 12 of the guide member 2, and as shown in FIG. 5, a disk-shaped main body 31 and four cross-shaped main body 31 extending in a cross shape. The arm portions 32, 32, 32, 32 are integrally formed. The main body 31 is connected to the drive device 5 by its rotation shaft 33, and is rotated in one direction by the drive device 5. A free roller 34 is rotatably attached to the tip of each arm 32, and the free roller 34 pushes the center of the lower surface of each bucket 3 as the main body 31 rotates. In this case, the disposition position of the free roller 34 between the arm portions 32 corresponds to the length of the bucket 3, and the bucket 3 approaching the lower guide portion 12 of the guide member 2 is moved by one arm portion 32. While pushing, the next arm portion 32 pushes the next bucket 3 and continuously sends the bucket 3 without a gap.

As shown in FIG. 2, the drive device 5 transmits the rotational power of the drive motor 41 to the rotary shaft 33 of the lift member 4 via the chain 42. The output shaft 41a of the drive motor 41 and the rotary shaft 33 are respectively provided with pulleys 43, 4
4 is fixed, and the rotation of the drive motor 41 is decelerated and transmitted to the lift member 4.

Here, the lift-up operation of the coin C will be described with reference to FIG. When the lift member 4 rotates using the drive motor 41 as a power source, each arm portion 32 of the lift member 4 pushes the buckets 3 in the lower guide portion 12 forward one by one. The bucket 3 is guided by the guide member 2, goes around the lower guide portion 12, is guided to the ascending guide portion 13, and ascends while being pushed up. When the bucket 3 starts to rise, the arm portion 32 moves to the bucket 3
Although it is disengaged from the lower surface, it is pushed by the following bucket 3 and rises as it is. In this way, in the rising guide portion 13 of the guide member 2, the buckets 3 are pushed up one after another, and the buckets 3 are continuously lifted without a gap so that the buckets 3 are stacked.

On the other hand, the bucket 3 which has started to rise faces the coin inlet 6 and receives the coin C randomly sent from the coin inlet 6 as appropriate. The coin C received in the bucket 3 is transferred to the bottom plate 2 toward the back of the bucket 3.
Although it slides on the top 2, it hits the coin receiving plate 8 and slides up against the coin receiving plate 8 and rises while riding on the bucket 3. When the bucket 3 carrying the coin C reaches the position of the coin outlet 7, the coin C is detached from the upper end of the coin receiving plate 8 and slid down from the bottom plate 22 of the bucket 3 to be delivered to the coin outlet 7. .

The bucket 3 which has delivered the coin C to the coin outlet 7 further rises and wraps around the upper guide portion 11 of the guide member 2. Here, the bucket 3 that has passed through the top portion of the upper guide portion 11 descends due to its own weight so as to drop the descending guide portion 14 of the guide member 2,
The lower end of the descending guide portion 14 abuts against the arm portion 32 of the lift member 4 and stops. After that, the bucket 3 is pushed out again by the lift member 4.

As described above, according to the lift device of this embodiment, the bucket 3 is moved by the pair of left and right guide members 2 and 2 and the lift member 4, so that the structure is simple and the assembly is performed. It is easy and inexpensive to construct. Moreover, since it is not necessary to arrange the buckets 3 side by side with the descending guide portion 14 of the guide member 2, the buckets 3 in this portion can be omitted, and also in this respect, the structure can be inexpensive.

On the other hand, each bucket 3 in the ascending process is
The insertion structure allows the coins C randomly introduced from the coin introduction port 6 to be received in any one bucket 3 reliably because the gaps do not occur and overlap. Also, on the coin outlet 7 side, the coin receiving plate 8 is made to relatively function as a gate, and the coin C is transferred to the bucket 3.
Since the coin C is slipped off and sent to the coin delivery port 7, the coin C can be reliably delivered to the coin delivery port 7. Therefore, it is possible to structurally prevent an error in transporting the coin C.

In this embodiment, the guide member and its guide groove have a track shape. However, the guide member may have any shape such as an ellipse as long as the guide groove has a circular shape. . Further, the lift member may be like a ratchet wheel, or may be one that sends out a bucket by reciprocating motion. Furthermore, the bucket is continuous (connected) in the circumferential direction of the guide member.
You may have.

[0027]

As described above, according to the lift device of the present invention, the bucket is guided by the guide member, and is lifted by the lift member to be circulated and moved, so that the structure can be simplified. Assembling can be facilitated, and as a whole, the transport function is not hindered and the cost can be reduced.
