Description

The present invention relates to a coin transporter, and is particularly effective when used as a coin lift for transferring coins from a low place to a high place.

[Prior Art] For example, in a game arcade where a coin gaming machine is installed, it is necessary to supply coins to each coin gaming machine. Transported and distributed to gaming machines.

In addition, a coin exchange is provided at a prize exchange place, a counter, or the like of a game hall in order to pump coins collected from a player to a coin transfer device.

Conventionally, as a coin lift, for example, two belts are superposed, a collected coin is sandwiched between them, and the coins sandwiched between the belts are conveyed by pivotally supporting the belts separately above. It is designed to be sent to equipment.

Alternatively, coins are fed one by one by a coin lift provided with a large number of coin buckets each having an arc-shaped coin locking portion (coin receiver) corresponding to the outer circumference of the coin.

[Problems to be Solved by the Invention] However, in the former case, since the surface of the coin is smooth and flat, the coins are likely to slip when overlapped, and the force for sandwiching the coin between the two belts is likely to be insufficient. Therefore, even if the coin is once sandwiched between the belts, it may slip down during transfer. Therefore, there is a problem that it is difficult to reliably pump a large amount of coins upward.

Also, with the latter one, it is necessary to supply coins one by one to the coin bucket of the coin lift, so it is necessary to arrange the coins in advance. Since the coins can be pumped only one by one, it takes time to pump a large number of coins, and there is a problem that a coin shortage is likely to occur in the coin gaming machine.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coin carrier capable of reliably pumping slippery coins, and particularly capable of reliably pumping a large number of coins upward.

[Means for Solving the Problems] In order to achieve the above object, a coin carrier according to the present invention has a large number of transfer bodies, which are continuously fixed to the outside of an endless chain, arranged between side walls at predetermined intervals. And a coin transfer path having an inclined portion is formed to move the transfer body by driving the endless chain to transfer coins, wherein each transfer body moves to a coin stacking surface side. A coin locking wall of a predetermined height is formed on the rear end side of the flat surface portion and has a flat surface portion along the direction, and both side end portions and side wall surfaces of the locking wall are formed. A gap larger than the thickness of the coin and smaller than the diameter of the coin, and / or a notch in the middle of the locking wall that communicates in the transfer direction larger than the thickness of the coin and smaller than the diameter of the coin. Is formed It is characterized in.

[Action]

According to the present invention, when a coin is placed on the flat portion of the transfer body fixed to the outside of the driven endless chain, the coin is moved in the moving direction by the coin locking wall provided at the rear end side of the flat portion in the moving direction. The transfer force of is given.

Here, a gap having a size larger than the thickness of the coin and smaller than the diameter of the coin is formed between the side walls at both ends of the locking wall. Therefore, when the coin is placed on the transfer body, the angle of the coin with respect to the plane portion of the transfer body is large,
For example, when there is a right-angled coin, the coin rolls, passes through the above-mentioned gap, falls off the transfer body, and falls. Then, only the coins placed substantially parallel to the plane portion of the transfer body are reliably transferred without dropping from the gap.

EFFECT OF THE INVENTION In the present invention, since the transfer body is provided with the locking portion,
Even if the coin transfer path is inclined, the coins can be transferred reliably, so that it can be used as a coin lifter (coin lift) for transferring from a low place to a high place.

At this time, since a gap that is larger than the thickness of the coin and smaller than the diameter of the coin is formed between the locking wall and the side wall, even if the transfer body passes through the coin collecting section where the coins are piled up. , The coins are automatically sorted, and only the coins correctly placed on the flat surface are transferred by the transfer body.
If it does not load properly, it will be dropped from the transfer body.

Therefore, even if the coins are not arranged in the coin collecting unit, the piled coins can be reliably transferred in a fixed amount.

Furthermore, by setting the shape or size of the locking portion of the transfer body to the coins to be transferred, the number of transferred coins can be grasped to some extent, and by appropriately setting these, the transferred coins can be It can also be counted.

EXAMPLES Next, the present invention will be described based on examples.

The coin lift 10 of the present embodiment shown in FIG. 1 transfers game coins to a coin carrier 1 arranged at an upper part of an island where a coin game machine (not shown) is installed in a coin game hall or a pachinko game hall, To supply.

As shown in FIG. 2, the coin lift 10 includes a main body 11 in which a plurality of sprockets 21, 22, and 23 are rotatably supported and arranged, and a transfer conveyor 30 is attached to the sprockets 21 to 23 to transfer the sprockets. A curved guide 24 and a straight guide 25 for sliding the transfer conveyor 30 are provided on a part of the outside of the conveyor 30.

Further, the sprocket 22 has a driving gad motor 26
The output shafts of are connected.

The main body 11 is formed by integrating a pair of side plates 12 arranged at a predetermined interval corresponding to the width of the transfer conveyor 30 by some coupling members, and coins collected at a counter of a game hall or the like are carried in. Coin collecting section 11A, coin transferring section 11B for transferring the coins in the coin collecting section 11A above the island, and coin discharging for discharging the transferred coins to the coin conveyor 1 arranged on the upper part of the island Part 11C
Are provided in order from the bottom.

In the coin collecting portion 11A, the sprocket 21 is rotatably supported by the side plate 12 by a bearing member (not shown),
A sprocket 22 driven by a gad motor 26 is arranged at a position substantially horizontal to the sprocket 21.

On the other hand, a sprocket 23 is provided above the sprocket 22 in the coin ejection portion 11C.

Further, the coin discharging portion 11C is formed with a discharging slit 13 for discharging the transferred coins.

At the coin transfer unit 11B between the coin collecting unit 11A and the coin discharging unit 11C, the transfer conveyor 30 is directly connected to the curved guide 24 in order to slidably support the transfer conveyor 30 from the outside between the sprocket 21 and the sprocket 23. The guides 25 are provided side by side along the transfer conveyor 30.

The curved guide 24 slidably supports the transfer conveyor 30 moving upward from the sprocket 21 to give a predetermined inclination angle to the transfer conveyor 30, and the transfer conveyor 30 slides the curved guide 24. Change the direction of movement while moving.

Here, the curved guide 24 gives an inclination angle of 45 degrees to the transfer conveyor 30, and changes the traveling direction of the transfer conveyor 30 to the vertical direction after sliding.

The straight guide 25 prevents the coins transferred to the transfer conveyor 30 sliding on the curved guide 24 from falling from the transfer conveyor 30 during the transfer, and the coin ejecting unit 1
Lead to 1C.

The discharge slit 13 is formed on the side plate 12 corresponding to the traveling position of the transfer conveyor 30 described later, and the coin to be discharged is provided outside the side plate 12 provided with the discharge slit 13. A coin guide box 14 for leading to 1 is provided.

The transfer conveyor 30 includes an endless roller chain 31 stretched outside the sprockets 21 to 23, and a large number of coin buckets 40 continuously fixed to the outside of the roller chain 31.

The roller chain 31 has a pin link 33 provided with an attachment 32 for fixing the coin bucket 40.
Are arranged at predetermined intervals, and coin buckets 40 are fixed to the attachments 32 by screws 34. Here, the coin buckets 40 are set to have a gap of 1.1 mm at a place where the roller chains 31 are linearly arranged.

As shown in FIG. 3, the coin bucket 40 includes a flat coin base 41 and a wall portion 46, which are integrally formed of resin.

Here, polyamide (nylon 66) is used as an engineering plastic which is tough and self-lubricating, but other engineering plastics such as polycarbonate and polyacetal may be used.

The coin board 41 has left ends 42 and right ends 43 which are parallel to each other and which are parallel to each other, corresponding to the side plates 12 arranged in parallel at a predetermined interval. A clearance is provided so that the 40 can move smoothly.

The front end 44, which is the direction of travel, is formed in a curved shape with the center of the front end having a convex arc and the opposite sides of the front end having a concave arc, and the rear end 45 is also shown in FIG. As described above, a concave arc is formed in the center and convex arcs are formed on both sides of the coin bucket 40, corresponding to the front ends 44 of the coin buckets 40 provided in front and rear.

As a result, the gap between the coin buckets 40 provided in front of and behind is curved, so that the coin is less likely to be caught.

The wall portion 46 is formed to have a vertical surface protruding from one surface of the coin table 41, and is provided along the traveling direction so as to separate the surface of the coin table 41 into two parts, left and right. The wall 47 and the locking wall 48 forming the rear end face together with the rear end 45 of the coin stand 41 are joined at the rearmost portion of the separation wall 47.

The tip of the separation wall 47 is provided with an inclined portion 47a whose height from the coin stand 41 is lowered toward the tip side, and an arcuate recess 47b is formed in the middle of the separation wall 47.

As a result, when the coin bucket 40 slides along the curved guide 24, as shown in FIG. The coin bucket 40 comes into contact with the curved guide 2 since it comes into contact with the concave portion 47b at two locations on both ends thereof.
Stable against 4

A front surface 48a of the locking wall 48 has a sloped surface in which a connecting portion with the separation wall 47 is located at the most front and forms an arc with the separation wall 47, and gradually recedes toward both sides.

Here, an angle of about 70 degrees is set with respect to the side plate 12, but an acute angle of less than 90 degrees and particularly 85 degrees or less may be used.

As a result, the transferred coins move toward both sides due to their own weight, but in the coin transfer section 11B, the side plate 1
Since it cannot be moved by 2, the coin moves to the upper side as it is along the side plate 12, and in the upper coin discharging part 11C passing through the coin transfer part 11B, it can pass through the discharging slit 13 of the side plate 12, and the coin guiding box 14 automatically. Is discharged to.

Notches 49 are formed at both ends of the locking wall 48. Due to the notch 49, a gap 50 larger than the thickness of the coin and smaller than the diameter of the coin is formed between the locking wall 48 and the side plate 12. Therefore, when the coin is locked in the coin collecting unit 11A, when the coin is in a standing state such as being perpendicular to the coin base 41, the coin is rolled by the locking wall 48 and transferred. Without moving, it gradually moves along the inclined front surface 48a, passes through the gap 50 and comes off the coin base 41, so that the coin is not caught and the transfer conveyor 3
0 moves smoothly.

At the rear part in the middle of the locking wall 48, the locking wall 48 of the coin bucket 40 and the inclined part 47 of the separation wall 47 provided in front and rear.
A recess 48b is formed in order to avoid contact with a.

With the above structure, the coin lifter 10 of this embodiment operates when the gad motor 26 operates to drive the sprocket 22 and the roller chain 31 travels.
In A, the coins collected at the counter of the game hall or the like fit in the coin base 41 of the coin bucket 40, are received by the locking wall 48, and slide with the side plate 12 to move together with the coin bucket 40.

At this time, even if coins are stacked higher than the height of the wall portion 46 on the coin base 41, the coins can pass over the wall portion 46 because the transfer conveyor 30 is inclined in the coin collecting portion 11A. Since it slips down, coins can be transferred smoothly without special tidying up.

Further, if the coin does not fit into the coin base 41 properly and becomes vertical to the traveling direction of the coin base 41 and the coin bucket 40, the coin does not move together with the coin bucket 40 and exits from the gap 50, and the coin collecting unit 11
Remain in A.

Further, when the coin is locked only in a part of the locking wall 48 and does not fit properly into the coin base 41, the coin is disengaged from the coin bucket 40 when the side wall 12 is rolled by the force received from the coin bucket 40.

In addition, even if coins are likely to be caught between the coin buckets 40, the gap between the front end 44 and the rear end 45 of the coin bucket 40 has a curved shape, so that the interval between the coin buckets 40 changes. When doing so, the coins are flipped out from between the coin buckets 40.

When the coin bucket 40 is transferred, the curved guide 24
Since the recess 47b is formed in the separating wall 47, the partition wall 47 makes stable contact with the curved guide 24, and an appropriate gap is provided between each coin bucket 40. The coin bucket 4 by the curved guide 24.
Even if 0 is located inside the roller chain 31, the coin buckets 40 do not come into contact with each other and slide smoothly.

When the coin bucket 40 slides on the straight guide 25, the coin is covered by the straight guide 25, and when the coin bucket 40 slides on each of these guides 24, 25, the wall of the coin bucket 40. Since the coin chamber is formed by the portion 46, the side plate 12, and the guides 24 and 25, the transferred coin does not drop.

At the portion of the straight guide 25, the coin bucket 40 is substantially vertical and receives a force that moves outward due to the inclination of the front surface 48 a of the locking wall 48.

When the coin is transferred to above the main body 11, the side plate 12 has a discharge slit 13 formed therein. Therefore, the coin passes through the discharge slit 13 and the coin guide box 14 to the coin carrier 1. Is discharged.

In the present embodiment, since the locking wall 48 forms an acute angle with the side plate 12, a gap 50 is provided between both ends of the locking wall 48 and the side plate 12 for dropping a standing coin.
However, when the locking wall 47 does not form an acute angle with the side plate 12 or when the shape of the locking wall 47 is different, a deletion portion (a cutout in the transfer direction) is provided at another place, The locking wall may be separated into a plurality of pieces.

As described above, in the coin lift 10 of the present embodiment, a large amount of coins can be reliably pumped without being caught in the middle, and the pumped coins can be automatically discharged.

Further, since the number of coins to be pumped can be set depending on the shape of the coin bucket 40, the management of coins becomes easy.

In the above embodiments, the size of the coin table of the coin bucket is set so that two coins are lined up. However, the size may be set such that one coin is placed on one side, or a plurality of coins are arranged in the traveling direction. Coins may be placed.

Further, a through hole or the like may be formed in the flat surface portion within a range that does not impair the strength to reduce the weight.

Further, although the gad motor is configured to drive the sprocket of the coin collecting unit, it may be configured to drive the sprocket of the coin discharging unit.

Further, the number of sprockets is not limited to 3, and may be 4 or more.
