Abstract

PURPOSE:To prevent coins from being sandwiched between respective buckets by matching the neighboring portions of the buckets themselves in curved shape. CONSTITUTION:When a sprocket 22 is driven by the operation of a geared motor 26 and a roller chain 31 travels in a coin lift 10, coins recovered by a counter or the like of a game place fit in a coin bed 41 of a coin bucket 40 in a coin collecting section 11A to be received by a stop wall 48 and transferred together with the coin bucket 10 while sliding and rolling on a side plate 12. Even if the coin is going to be sandwiched between the coin buckets 40, the coin is filliped from between the coin buckets 40, since a gap between the front and rear ends 44, 45 of the coin bucket 40 is curved, when the gap between the coin buckets is varied. Thus, the coin having a linear section is not sandwiched between the buckets themselves so that a great number of coins can be surely lifted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coin lift for transferring coins from a low place to a high place.

[Prior Art] For example, in a game hall where coin game machines are installed, coins must be supplied to each coin game machine, so the coins are transported by various coin conveying devices installed above the coin game machines. Transported and distributed to gaming machines.

In addition, coin lifts are installed at prize exchange places, counters, and the like in game parlors in order to transport coins collected from players to a coin transport device.

Conventionally, coin lifts have, for example, placed two belts one on top of the other, sandwiched the collected coins between them, and supported the belts separately in rotation above, thereby transporting the coins sandwiched between the belts. The material is then transported to equipment, etc.

Alternatively, coins are lifted one by one using a coin lift equipped with a large number of coin buckets each having an arcuate coin locking portion (coin receiver) corresponding to the outer circumference of the coin.

[Problem to be solved by the invention] However, in the former case, since the coins have smooth and flat surfaces, they tend to slip when they overlap, and the force to sandwich the coins between the two belts tends to be insufficient. Therefore, even if a coin is once caught between the belts, it may slip off during transport. Therefore, it is possible to securely collect a large amount of coins by 1. There is a problem in that it is difficult to transport the

In addition, with the latter type, the coins must be fed one by one to the coin bucket of the coin lift, so it is necessary to organize the coins in advance. Since only one coin can be transported, it takes time to transport a large amount of coins, and there is a problem in that the coin gaming machine is likely to run out of coins.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coin lifting machine that can reliably transport slippery coins, and in particular, can reliably transport a large number of coins upward.

[Means for Solving the Problems] The present invention provides a coin transfer path in which a large number of buckets fixed to the outside of an endless chain are arranged between side walls provided at predetermined intervals, and the endless chain is driven. In the coin transport machine for moving the buckets, the technical means is that the buckets are provided close to each other, and the adjacent portions of the buckets are curved to match each other.

[Function] In the present invention, on the outside of the endless chain being driven,
Because a large number of buckets are fixed close to each other,
When the bucket passes through the storage area where the coins are stored,
Coins are scooped into each bucket one after another, enter the buckets, and are transferred upward.

When a coin is scooped into a bucket, if the coin is about to get stuck between the buckets 1 and 1, the buckets are placed close to each other, and the gaps are small, and the buckets are close to each other. Since the section is curved, coins with a straight cross section will not get caught in the gap between the buckets.

Therefore, when the endless chain is driven, the coin bucket moves smoothly within the coin storage section, and a large amount of coins can be reliably transported.

[Effects of the Invention] In the present invention, since the buckets are provided close to each other on the outside of the endless chain, when the endless chain is placed through the coin storage section in which coins are stored, each bucket scoops up the coins, At this time, since coins are not caught between the buckets 1, a large amount of coins can be transported without requiring special equipment for organizing coins.

[Example] Next, the present invention will be explained based on examples.

The coin lift 10 of this embodiment shown in FIG. 1 is used in a coin game hall or a pachinko game hall to transport coins for games to a coin transport machine 1 placed in the second part of an island where coin game machines (not shown) are installed. Transport and supply.

The coin lift 10, as shown in FIG. 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.

In addition, the sprocket 22 is equipped with a geared motor 26 for driving.
The output shafts of the two are connected.

The main body 11 is made by integrating a pair of side plates 12 arranged at a predetermined interval corresponding to the width of the transfer conveyor 30 with several connecting members, and is used to carry coins collected at a counter of a game hall, etc. a coin collecting section 11A, a coin transferring section 11B for transferring the coins in the coin collecting section 11A to the upper part of the island, and a coin discharging section 11B for discharging the transferred coins to the coin conveying machine 1 arranged above the island. Part 11C
are arranged in order from the bottom.

In the coin collector M11A, a bearing (not shown) of a sprocket 21 is rotatably supported by a member on the side plate 12, and a sprocket 22 driven by a geared motor 26 is positioned approximately horizontally with respect to the sprocket 21. It is arranged.

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

Further, a discharge slit 13 for discharging transferred coins is formed in the coin discharge section 11C.

The coin transfer section 11B between the coin collecting section 11A and the coin discharging section 11C is provided with a curved guide 24 and a straight line in order to slidably support the transfer conveyor 30 from the outside between the sprocket 21 and the sprocket 23. shaped guides 25 are arranged in order along the transfer conveyor 30.

The curved guide 24 slides and supports the transfer conveyor 30 that moves in one direction from the sprocket 21 and gives a predetermined inclination angle to the transfer conveyor 30. Change the direction of movement while sliding.

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

The straight guide 25 prevents coins transferred to the transfer conveyor 30 that have slid on the curved guide 24 from falling off the transfer conveyor 30 during transfer.
Lead to 1C.

The ejection slit 13 is formed on the side plate 12 in correspondence with the running position of the transfer conveyor 30, which will be described later.The outer side of the side plate 12 provided with the ejection slit 13 is provided with the coin conveyor 30 to be ejected. A coin guide box 14 is provided to guide the coins to 1.

The transfer conveyor 30 consists of an endless roller chain 31 stretched outside each of 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 includes a bin link 33 with an attachment 32 for fixing the coin bucket 40.
are arranged at predetermined intervals, and a coin bucket 40 is fixed to each attachment 32 with a screw 34. Here, the intervals between the coin buckets 40 are set so that there is a gap of 1.1- in the place where the roller chain 31 is arranged in a straight line.

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

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

The coin stand 41 has a left end 42 and a right end 43 parallel to each other in the direction of travel, corresponding to the side plates 12 arranged in parallel at predetermined intervals, and is provided close to the side plates 12, with a coin bucket between them. Clearance is provided to allow smooth movement of 40.

Further, the front end 44, which is in the direction of travel, is formed in a curved shape with a convex arc toward the front at the center and concave arcs on both sides, and the rear end 45 is also shown in FIG. As shown, a concave circular arc is formed in the center and convex circular arcs are formed on both sides of the front end 44 of the coin bucket 40 provided at the front and rear sides.

As a result, the gaps between the coin buckets 40 provided one behind the other become curved, making it difficult for coins to get caught.

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

At the tip of the separation wall 47, an inclined portion 47a is added which is lower in height from the coin stand 41 on the tip side, and an arc-shaped recess 47b is formed in the middle portion of the separation wall 47.

As a result, when the coin bucket 40 slides on the curved guide 24, as shown in FIG. Since the coin bucket 40 contacts the guide 24 at two places on both ends of the recess 47b, the coin bucket 40 contacts the curved guide 24.
It slides stably against 4.

The front surface 48a of the locking wall 48 forms a slope such that the joint portion with the separation wall 47 is located at the frontmost position, forms an arc together with the separation wall 47, and gradually recedes toward both sides.

Here, the angle is set at about 70 degrees with respect to the side plate 12, but any acute angle less than 90 degrees, 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
2, the coin cannot be moved upwardly along the open plate 12, passes through the coin ejecting slit 13 of the side plate 12 at the upper coin ejecting part 11C after passing through the coin transporting part 11B, and is automatically removed from the coin guiding box 14. is discharged to.

Locking! ! 48 has a deleted portion 49 that is shorter than the width of the coin stand 41 at both ends thereof. As a result, when a coin is locked in the coin collecting section 11A, if the coin is in an upright position such as perpendicular to the coin stand 41, the coin will not roll away due to the locking wall 48. The coins are not transported by the coins, but gradually move outward along the sloped front surface 48a, pass through the deletion section 49, and come off the coin stand 41, so that the coins are not caught in the coins.
The transfer conveyor 30 moves smoothly.

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

With the above configuration, in the coin lift 10 of this embodiment, when the geared motor 26 is operated to drive the sprocket 22 and the roller chain 31 runs, the coin collecting section 11
Inside A, coins collected at the counter of the game hall, etc., fit into the coin stand 41 of the coin bucket 40, and are stopped by the locking wall 48, and the coins are slid and rolled on the opening plate 12 with r and h, and the coins'< :, ll I +17HJ: La L'-(l dri) I ru.

At this time, even if the coins are piled up higher than the height of the wall part 46 on the coin table 41, the coins will climb over the wall part 46 in the coin collecting part 11A because the transfer conveyor 30 is provided at an angle. Special F for slipping down! ! Coins can be transferred smoothly without tidying up.

Furthermore, if the coin does not fit into the coin stand 41 properly and becomes perpendicular to the direction of movement of the coin stand 41 and the coin bucket 40, the coin will not move together with the coin bucket 40 and will be pulled out from the removal section 49. Collection part 1
Remains within 1A.

Further, if the coin is locked only in a part of the locking wall 48 and does not fit properly into the coin stand 41, it will come off from the coin bucket 40 when it rolls on the side plate 12 due to the force received from the coin bucket 40.

In addition, even if a coin is about to get caught between the coin buckets 40, the gap between the front end 44 of the coin bucket 40 and the one-step distance 1i45 is curved, so the coin lift l-/ If the interval between L0 changes by 1[-4,
The coin is ejected from the coin bucket 40rWJ.

When transported, the coin bucket 40 is guided by the curved guide 24.
However, since the separation wall 47 has a recess 47b, it can stably contact the curved guide 24, and an appropriate gap is provided between each coin bucket 40. coin bucket 4 by the curved guide 24.
Even if the coin bucket 40 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 guides 25, the coins are covered by the straight guides 25, and when the coin bucket 40 slides on each of these guides 24.25, the coins are covered by the walls of the coin bucket 40. Since a coin chamber is formed by the portion 46, the side plate 12, and each guide 24, 25, the transferred coins will not fall out.

In the portion of the straight guide 25, the coin bucket 40 is substantially vertical and is subjected to an outward movement force due to the inclination of the front surface 48a of the locking wall 48.

When the coin is transferred above the main body 11, the coin passes through the ejection slit 13, passes through the coin guide box 14, and is transferred to the coin conveyor 1, since the ejection slit 13 is formed in the side plate 12. be discharged.

As described above, the coin lift 10 of this embodiment can reliably transport a large amount of coins without getting caught in the middle, and can automatically discharge the transported coins.

Furthermore, the number of coins to be transported can be set depending on the shape of the coin bucket 40, which facilitates coin management.

In the above example, the size of the coin stand of the coin bucket is set so that two coins can be placed side by side, but it may be set so that only one coin can be placed on one side, or the size can be set so that only one coin can be placed on one side, or multiple coins can be placed in the direction of travel. A coin may be placed on it.

In addition, although a continuous locking wall is shown with removed portions provided at both ends, a plurality of removed portions may be formed between the locking walls so that multiple walls can be provided continuously. Good too.

Further, a through hole or the like may be formed in the flat portion to the extent that the strength is not impaired, and the number of needles may be increased.

Furthermore, although the geared motor is configured to drive the sprocket of the coin collecting section, it may also be configured to drive the sprocket of the coin ejecting section.

Further, the number of sprockets is not limited to three, but may be four or more.
