Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a coin transport device that prevents clogging of coins that are likely to occur when a large number of coins transported on a belt are turned 90 degrees and carried out. .

(Prior Art) In a device provided with a mechanism for conveying coins such as a vending machine, a money changer, and a cash dispenser for accumulating and paying out coins, each constitution of the conveying mechanism and the like is required due to a demand for downsizing of the entire device Ingenuity is being made to reduce the size of the part.

For example, in the conventional conveying section shown in FIGS. 3A and 3B, when the coin 2 conveyed by the belt 1 is carried out from the leading side in the conveying direction of the belt onto the slide stand 3, the slide stand 3 is moved to the belt 1. By connecting on the extension of the conveying direction, the conveying locus extending in the same straight line direction is drawn as a whole. Therefore, the total length of the belt 1 and the slide 3 becomes long, which causes a problem of increasing the size of the device.

From such a point, the linear baffle plate 5 as shown in FIG. 4 (a) is set on the belt 1 with the inclinations set at 45 degrees, and the slide is mounted on the belt side so as to be orthogonal to the belt. By connecting 3, the carry-out direction can be changed by 90 degrees to achieve miniaturization.

As shown in FIG. 3A, one end 5a of the baffle plate 5 is brought out of the carry-out port 6
If it is provided at a position separated by a predetermined distance 1 from, a sufficient space can be formed between the carry-out port 6 and the baffle plate.
The coin that hits the baffle can move relatively smoothly onto the slide 3 through the transfer port 6, but it requires a space corresponding to the distance l, which is an obstacle to miniaturization.

Therefore, it may be possible to dispose the end 5a of the baffle plate in contact with the carry-out port 6 as shown in FIG. 7B, but in this case, the space between the carry-out port and the baffle plate becomes narrow. Therefore, the coins are easily jammed as shown in the figure.

In order to prevent such clogging, it is effective to form the baffle plate 5 into a curved shape as shown in FIG. 5, but the curved baffle plate is used for the following reasons. There was no

That is, in FIG. 6 (a), reference numeral 10 indicates a roller supporting the endless belt 1, and the roller 10 has a crown shape in which the central portion is swollen in order to prevent the belt from coming off. However, when the belt is driven by using this roller, both widthwise end portions of the belt 1 are curved upward as shown in FIG. If the baffle is straight, the coin is pushed out by a sufficiently large component force, so that the coin can be moved toward the slide 3 on the belt surface curved upward, but the curved baffle In this case, since the component force for pressing the coin is small, the coin cannot be moved over the curved belt surface. For such a reason, conventionally, the actual condition is to use the transport device having the structure shown in FIG. 4 (a) using the linear baffle plate.

In addition, in Japanese Utility Model Publication No. 47-26862, a technique is disclosed in which a cylindrical wooden pipe is turned diagonally forward in the process of being conveyed by a belt. By arranging the extending baffle plate at a position higher than the original belt surface, by arranging a protruding piece on the lower surface of the belt immediately before the baffle plate and lifting the belt,
The belt surface is raised to the lower edge of the baffle. In addition, this protruding piece extends over almost the entire length of the belt in the width direction, and by supporting the lifted belt surface flat over the entire width, it stabilizes the transportability of the long wooden pipe during the direction change. There is.

However, in this conventional example, an object whose diameter is much smaller than the widthwise length of the belt, such as a coin, and whose transportability is greatly affected by changes in properties such as the curvature of the belt is regarded as a transport target object. However, it is clear that even though the same transfer direction changing technology is used, it is based on an idea completely different from the coin transferring technology. In particular, coin transfer is premised on the use of crown rollers and curved baffles, and since it is a direction change within a limited narrow space such as a vending machine, it is necessary to change to the orthogonal direction. Therefore, it is necessary to develop a technique for simultaneously satisfying these conflicting conditions, and the present application solves this problem all at once.

(Purpose of the Invention) The present invention has been made in view of the above, and by using a curved baffle, the device can be downsized, coins can be prevented from being jammed, and defective delivery due to the bending of the belt can be prevented. It is an object of the present invention to provide a coin transfer device capable of solving the above problem.

(Summary of the Invention) In order to achieve the above object, a coin transfer device of the present invention is an endless transfer belt for linearly transferring a plurality of coins placed on the upper surface of an upper traveling surface, and the endless transfer belt. At least two crown-shaped rollers for stretching the conveyor belt, a baffle plate for redirecting and ejecting the coin to an outlet located in a direction orthogonal to the conveying direction of the conveyor belt, and the baffle plate And a sliding plate that supports the lower surface of the upper running surface of the belt, and the baffle plate hit by the coin is formed into a concave curved surface, and the concave outlet of the baffle plate is carried out. The end portion on the side is made to extend in a direction substantially orthogonal to the transport direction of the transport belt, and on the sliding plate located immediately before the baffle plate, in sliding contact with the lower surface of the upper traveling surface of the transport belt. Lift a part of the conveyor belt A protrusion for controlling the bending is arranged, and the protrusion is configured to lift the central portion in the width direction of the conveyor belt so that at least the edge of the conveyor belt on the outlet side is inclined downward toward the outlet. It features.

(Embodiment) Hereinafter, a coin carrying device of the present invention will be described in detail based on an embodiment shown in the accompanying drawings.

1 (a), (b) and (c) are a plan view, an AA front view and a BB sectional view showing the structure of an embodiment of the present invention, which is endless by a crown-shaped roller 20. A slide plate 23 is attached just below the upper running surface of the belt 21 stretched over the belt. The surface 25a of the baffle plate 25 with which the coin abuts is formed in a concave curved surface, while the carry-out table 26 for carrying out the coin 27 guided along the surface 25a is orthogonal to the transport direction of the belt 21. Connected in the direction.

A protrusion 30 for restricting the bending of the belt is formed in the center of the sliding plate 23, and the position thereof is preferably a portion corresponding to the carry-out port 26a of the carry-out table 26. The presence of this protrusion 30 causes the belt 21
Since the central portion can be lifted as shown in FIGS. 1 (b) and (c), both widthwise end portions of the belt are inclined downward to facilitate the movement of the coin in the carry-out direction.

The protruding height of the curving restricting protrusion is sufficient to restrict the upward curving of both end portions of the belt shown in FIG. 6 (b), in other words, the curving height of both end portions of the belt upward. It is necessary to set a protrusion amount higher than that.

When the protrusion 30 is installed in the central portion in the width direction of the belt, the belt end portion on the side opposite to the carry-out port 26a also inclines downward, so that the inclination of the coin located at the portion hits the baffle plate. It may be difficult to climb up to the exit, but as is clear from Fig. 1 (a), the exit
Since the surface 25a of the baffle plate corresponding to the belt end portion (upper side in the figure) opposite to 26a has a gentle slope along the belt conveying direction, the baffle surface 25a is located between the surface 25a and the outlet 26a. A large enough component force is generated to move. Therefore, the coin can quickly go up toward the central portion of the belt without being stagnant. On the other hand, the surface 25a of the baffle plate corresponding to the belt end portion on the side of the carry-out port 26a forms a wall surface that is substantially orthogonal to the belt conveying direction as is clear from FIG. It is difficult to move it to the outlet unless the end is tilted down.

In addition, the formation position and shape of the curving protrusion 30 are the first.
The present invention is not limited to those shown in FIGS.
Various modifications are possible as long as the belt end facing the carry-out port 26a can be inclined downward.

For example, as shown in FIG. 2, a protrusion extending from the widthwise center of the belt to the other end (the side opposite to the carry-out port 26a) may be provided.

Note that the meaning of forming a protrusion on the slide plate includes not only the case where a particular protrusion is fixed to the slide plate but also the case where the slide plate itself is previously configured to integrally have the protrusion. .

As described above, the present invention provides the baffle plate having the curved butting surface when the coins conveyed by the belt are changed in the direction orthogonal to the belt conveyance direction and is conveyed out, and the belt is located at the front position of the baffle plate. Since the protrusion for bending control is arranged below and the end of the belt on the outlet side is inclined downward, all the coins that are conveyed on the belt and hit the baffle are quickly delivered to the outlet without delay. To be done. Moreover, the length of the conveyor belt can be shortened to the necessary minimum, and the device can be downsized.

(Effect of the Invention) As described above, according to the present invention, by using the curved baffle plate, the device can be downsized, coins can be prevented from being jammed, and defective delivery due to the bending of the belt can be eliminated. be able to.
