Description

[Detailed description of the invention] (Field of industrial application) The present invention is particularly applicable to a banknote conveying device installed inside an island in which two rows of pachinko machines are arranged back to back with a small distance between them. The present invention relates to a banknote return mechanism for returning banknotes when the banknotes are determined to be defective by an identification device.

(Prior Art) In recent years, bill ball lending machines and card-type ball lending machines have appeared that rent balls using 1000 yen bills or cards in thin inter-machine ball lending machines installed between pachinko machines. , a banknote conveyance device (hereinafter referred to as the conveyance device) that collects and stores banknotes or cards inserted into a predetermined place via a banknote introduction conveyance mechanism (hereinafter referred to as the introduction conveyance mechanism). ) was provided.

However, these banknote conveyance means sandwich the banknotes in the length direction using endless belts or endless belts and rollers, and transport the banknotes to the predetermined location. When the identification device installed in the rental machine determines that the banknote is defective, the banknote must be returned.

However, with the above-mentioned belt-based transport mechanism, the larger the surface area of the banknotes in contact with the belt, the greater the pulling force, and even defective banknotes are taken in and transported. It was hot.

Further, in order to solve these problems, a conveyance device has been provided which has a mechanism for making banknotes determined to be defective into a returnable state.

(Problem to be solved by the invention) A banknote return mechanism of an introduction conveyance unit proposed to prevent defective banknotes from being taken in in a conventional conveyance device uses an endless belt and a conveyance roller to collect banknotes. The drive pulley that drives the endless belt and the endless belt of the conveyor body that conveys the guided banknotes to the predetermined location are held in the length direction and guided to the conveyor body and collected and stored at a predetermined location. A drive pulley that drives the belt is provided in the conveyor body so that the pulleys coaxially abut each other via a spring, and the drive pulley of the conveyor body drives the drive pulley of the introduction conveyor. When a force opposite to the conveyance direction is applied at the introduction conveyance section, the drive pulley of the introduction conveyance section stops, and the banknotes are returned via the identification device, but the pulleys are brought into contact with each other. If the spring is too strong, even if a return force is applied, the drive pulley of the introduction conveyance section will rotate in sync with the drive pulley of the conveyance main body.On the other hand, if the spring is too weak, the endless belt of the introduction conveyance section will normally rotate. It no longer has enough rotational force to transport the Then,
It is difficult to adjust the spring.

Furthermore, since the above-mentioned banknote conveyance means is composed of an endless belt and a conveyance roller, the larger the area of the banknote in contact with the belt, the easier it is to be taken in, and the tip of the banknote is closer to the conveyor body. The closer one gets to the drive pulley for the introduction and conveyance unit, which is provided coaxially with the drive pulley inside the unit, the more problems arise, such as the banknotes being conveyed even though they have been determined to be defective banknotes.

In order to solve the above problems, it is desirable to synchronize the transport of the identification machine and the introduction transport section.
Controlling the conveyance speed at the same speed, or controlling the introduction conveyance section to instantaneously operate in reverse in response to the reverse rotation of the discriminator, is complicated, and the cost of the device is high, which is a major problem.

In the present invention, when the banknotes inserted into a transport device in which the recognition device and the introduction transport section are separated as a transport mechanism are determined to be defective by the recognition device, the banknotes that have entered the transport device are transferred to the recognition device. It is an object of the present invention to provide a banknote return mechanism for a banknote conveyance device that can reliably return banknotes without causing damage to the banknotes through reversal of the conveyance rollers.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a banknote introducing conveyance section which is pivoted to the side of the conveyance main body, and a conveyor which is rotationally driven by the banknote introduction conveyance section. A roller is provided, and a guide roller that rolls in contact with the conveyance roller by the urging of an elastic member is pivotally supported in the banknote introduction conveyance section through a loose fit hole, and the loose fit hole is provided with a guide roller that rolls in contact with the conveyance roller by the biasing force of an elastic member. It is characterized in that it is provided parallel to the orthogonal axis and is provided so as to restrict the biasing force.

(Function) The banknote return mechanism of the banknote conveyance device of the present invention configured as described above includes a plurality of conveyance rollers that are rotatably driven by motors at both ends of the introduction conveyance section and rotation of the conveyance rollers. Guide rollers that roll along the guide rollers are provided in contact with the conveyance rollers through the urging of elastic members, and banknotes are guided to the conveyance main body while being held between the respective rollers.

If the inserted banknote is determined by the identification device to be a counterfeit banknote or a defective banknote due to wrinkles, stains, folds, etc., a return force is applied in the opposite direction to the conveyance direction. At this time, the biasing of the guide roller shaft, which has the guide roller supported in the introduction conveyance section via the loose fitting hole and biased by the elastic member, is released, and the guide roller shaft moves slightly. A gap is created between the rollers, and as a result, the only thing that holds the banknotes is the conveyance roller of the identification device, so it is not possible to reliably return counterfeit or defective banknotes without any hindrance when returning the banknotes. It is a mechanism that can do it.

Unlike conventional conveying means, the banknotes are held and conveyed by point contact, so even if returning force is applied, the banknotes will not be damaged. Furthermore, when a returning force is applied, the guide roller shaft, which is supported through the loose fit hole and has the guide roller attached to it, releases the bias and moves slightly, thereby causing the gap between the rollers to move slightly. Since a gap is created and the banknotes are no longer clamped, there is no obstacle to returning the banknotes, and the banknotes can therefore be returned reliably.

In addition, the banknote identification device may determine that the inserted banknote is defective due to wrinkles, dirt, etc., even though it is a genuine banknote.
The effect is to completely eliminate troubles between the customer and the hall that conventionally occur when the banknotes are transported without being returned, and the simple mechanism works reliably without adding synchronized transport control between the identification device and the introduction transport section. The effect of making this possible is remarkable in the industry.
