The identification mechanism 30′ is disposed in a main passage 11′. The in-out port mechanism 20′ is connected with the main passage 11′ through a banknote incoming path 121′ and a banknote outgoing path 122′. The temporary storage mechanism 40′ is connected with the main passage 11′ through a temporary storage path 13′. Each of the plurality of circulating boxes 61′ is connected with the main passage 11′ through a corresponding circulating passage 14′. The recycling box 64′ is connected with the main passage 11′ through a recycling passage 15′. The loading box 60′ is connected with the main passage 11′ through a loading path 16′.

When performing a banknote withdrawal operation with such banknote processing device, banknotes would enter the main passage 11′ from the circulating box 61′ through the circulating passage 14′, and moves counterclockwise in the main passage 11′ to be conveyed to the identification mechanism 30′. Depending on the identification result of the identification mechanism 30′, qualified banknotes would be output to the in-out port mechanism 20′ through the banknote outgoing path 122′, while unqualified banknotes would continue to move counterclockwise to be recycled to the recycling box 64′ through the recycling passage 15′ for storage.

When performing a loading operation with such banknote processing device, banknotes in the loading box 60′ would enter the main passage 11′ through the loading path 16′, and then move clockwise in the main passage 11 to the identification mechanism 30′, and then keep moving clockwise in the main passage 11′. Depending on the identification result of the identification mechanism 30′, qualified banknotes would enter one of the circulating boxes 61′ through the corresponding circulating passage 14′, while unqualified banknotes would enter the recycling box 64′ through the recycling passage 15′.

When performing a loading and recycling operation with such banknote processing device, banknotes in the circulating box 61′ would enter the main passage 11′ through the circulating passage 14′, and then move counterclockwise in the main passage 11 to the identification mechanism 30′. The banknotes identified by the identification mechanism 30′ continues to move counterclockwise in the main passage 11′, where qualified banknotes would enter the loading box 60′ through the loading path 16′, while unqualified banknotes would enter the recycling box 64′ through the recycling passage 15′ for the storage.

When performing a banknote withdrawal operation from the loading box with such banknote processing device, banknotes in the loading box 60′ would enter the main passage 11′ through the loading path 16′, and then move clockwise in the main passage 11 to the identification mechanism 30′, and would keep moving in the clockwise direction in the main passage 11′, where qualified banknotes are output to the in-out mechanism 20′ while unqualified banknotes continue to move in the clockwise direction to be recycled to the recycling box 64′ for storage through the recycling passage 15′.

During the above-mentioned banknote withdrawal operation, loading operation, loading and recycling operation, and banknote withdrawal operation from the loading box, the banknotes would pass a junction (i.e., at a dotted line in FIG. 1) of the loading passage 16′ and the main passage 11′ whether the banknote moves counterclockwise or clockwise, where banknotes are easy to get jammed at the junction of the loading passage 16′ and the main passage 11′.

As shown in FIG. 5, when the user withdraws banknotes, the corresponding switching member is controlled to communicate the corresponding circulating passage 151 with the fourth path 214, and communicate the fourth path 214 with the third path 213. The banknotes are conveyed into the fourth path 214 from the circulating box 150 through the corresponding circulating passage 151, and then are delivered to the identification mechanism 130 through the third path 213 for identification. Depending on the identification result of the identification mechanism 130, when a banknote is determined as a qualified banknote, the corresponding switching member is controlled to communicate the second path 212 with the second banknote incoming path 232, the second banknote incoming path 232 with the connecting path 250, and the connecting path 250 with the first banknote outgoing path 241, and then the banknote is further conveyed to the outlet 120 through the second path 212, the second banknote incoming path 232, the connecting path 250, and the first banknote outgoing path 241 awaiting the user to take it away. Otherwise, when a banknote is determined as unqualified, the corresponding switching member is controlled to communicate the second path 212 with the first path 211, the first path 211 with the third passage 223, and the second passage 222 with the recycling passage 161, and then the banknote is conveyed to the recycling box 160 through the second path 212, the first path 211, the third passage 223, the first passage 221, and the recycling passage 161 for storage.

Referring to FIG. 6, there is shown a schematic view (the arrow and the thick solid line in the figure indicate the moving path of the banknotes) of the banknote processing device 10 when performing a loading operation according to an embodiment. The term “loading” means that the banknotes in the loading box 170 are delivered into a preset circulating box 150, that is, the banknote is replenished into the preset circulating box 150. The process is shown in FIG. 6, the corresponding switching member is controlled to communicate the loading passage 171 with the second passage 222, communicate the second passage 222 with the first path 211 of the main passage 210, and communicate the first path 211 with the second path 212. The banknotes in the loading box 170 are delivered to the identification mechanism 130 through the loading passage 171, the second passage 222, the first path 211, and the second path 212 for identifying the currency type and the state of the banknote. Depending on the identification result of the identification mechanism 130, when a banknote is determined as a qualified banknote, the corresponding switching member is controlled to communicate the third path 213 with the fourth path 214, and the fourth path 214 is controlled to communicate with the corresponding circulating passage 151 depending on the currency type of the banknote, and the banknote is delivered to the corresponding box 150 for storage through the third path 213, the fourth path 214, the corresponding circulating passage 151. By such a loading operation, the banknotes output from the loading box 170 are directly distributed to the corresponding circulating box 150, resulting in a high loading efficiency. When a banknote is determined as unqualified, the corresponding switching member is controlled to communicate the first passage 221 with the recycling passage 161, and the banknote continues to move to the first passage 221 along the fourth path 214 and is delivered to the recycling box 160 for storage through the recycling passage 161. Because the first passage 221 is in communication with the fourth path 214, and the junction of the recycling passage 161 and the first passage 221 and the junction of the loading passage 171 and the first passage 221 are sequentially arranged along the first passage 221, the qualified banknotes are delivered to the corresponding circulating box 150 along the fourth path 214, the unqualified banknotes are delivered to the first passage 221 along the fourth path 214 and are returned to the recycling box 160 through the recycling passage 161, while the loading box 170 continues to output the banknotes from the loading path 171 to the second passage 222. During the banknote loading process which the banknotes are delivered from the loading passage 171 into the main passage 210 through the second passage 222 and then from the main passage 210 into the first passage 221, they are always moving in a single direction, so that three operations can be simultaneously performed, including outputting banknotes from the loading box 170, conveying banknotes to the circulating box 150, and conveying banknotes to the recycling box 160, thereby improving the loading efficiency.

In an embodiment, the banknote processing device 10 may further have a loading and recycling function, where the loading and recycling of the banknotes means the banknotes of the circulating box 150 moving to the loading box 170.

The banknote in the circulating box 150 is delivered to the identification mechanism 130 after entering the fourth path 214 and the third path 213 through the circulating passage 151. Depending on the identification result of the identification mechanism 130, when a banknote is determined as qualified, the corresponding switching member is controlled to communicate the second path 212 with the first path 211, communicate the first path 211 with the third passage 223, communicate the third passage 223 with the first passage 221, and communicate the first passage 221 with the loading passage 171, and the banknote is delivered into the loading box 170 for storage along the second path 212, the first path 211, the third passage 223, the first passage 221 and the loading passage 171. When the banknote is determined as unqualified, the corresponding switching member is controlled to communicate the first passage 221 with the recycling passage 161, and the banknote is delivered into the recycling box 160 for storage through the first passage 221 and the recycling passage 161. In the above-mentioned loading and recycling process, the loading and recycling efficiency is high because the banknote moves in the first passage 221 and sequentially enters the loading passage 171 or the recycling passage 161 that are in communication with the first passage 221.

The banknote processing device 10 according to the present embodiment may also use the loading box 170 as the circulating box 150. That is, when the amount of the banknotes in the circulating box 150 is less than a set value, the withdrawal from the circulating box 150 may be stopped and the banknotes may be directly withdrawn from the loading box 170, thereby preventing the shutdown issues caused by a small amount of banknotes in the circulating box 150, thereby improving the operating efficiency.

Referring to FIG. 8, there is shown a schematic view (the arrow and the thick solid line in the figure indicate the moving path of the banknote) of the banknote processing device 10 when performing the withdrawal operation from the loading box 170 according to an embodiment of the present disclosure. As shown in FIG. 8, the corresponding switching member is controlled to communicate the loading passage 171 with the second passage 222, to communicate the second passage 222 with the first path 211, and to communicate the first path 211 with the second path 212. The banknotes in the loading box 170 enter the loading passage 171, the second passage 222, the first path 211, and the second path 212 and then are delivered to the identification mechanism 130. Depending on the identification result of the identification mechanism 130, when the banknote is determined as qualified, the corresponding switching member is controlled to communicate the third path 213 with the second banknote outgoing path 242, and to communicate the second banknote outgoing path 242 with the first banknote outgoing path 241, and the banknote is delivered to the outlet 120 through the third path 213, the second banknote outgoing path 242, and the first banknote outgoing path 241 awaiting the user to take it away. When the banknote is determined as unqualified, the corresponding switching member is controlled to communicate the third path 213 with the fourth path 214, to communicate the fourth path 214 with the first passage 221, to communicate the first passage 221 with the recycling passage 161, and the banknote is delivered into the recycling box 160 for storage through the third path 213, the fourth path 214, the first passage 221 and the recycling passage 161.

In order to secure the user's rights and interests, the banknote processing device 10 may also collect the banknotes that are not taken away by the user (simply referred to as the ignored banknotes) at the outlet 120 into the recycling box 160 for storage.

Referring to FIG. 9, there is shown a schematic view of the banknote processing device 10 when recycling ignored banknotes according to an embodiment (the arrow and the thick solid line in the figure indicate the moving path of the banknote). As shown in FIG. 9, the corresponding switching member is controlled to communicate the first banknote outgoing path 241 with the second banknote outgoing path 242, to communicate the second banknote outgoing path 242 with the third path 213, to communicate the second path 212 with the first path 211, to communicate the first path 211 with the third passage 223, to communicate the third passage 223 with the first passage 221, and to communicate the first passage 221 with the recycling passage 161.

The banknote processing device 10 provided by the present embodiment includes an auxiliary passage 220 which is annular. At most one bi-directional switching mechanism is arranged between adjacent passages of the auxiliary passage 220 to make the banknote move unidirectionally in the preset direction in the auxiliary passage 220. In the banknote withdrawal operation, the banknote does not pass through the junction of the loading passage 171 and the auxiliary passage 220. The banknote passes through the junction of the loading passage 171 and the auxiliary passage 220 only when performed the loading operation, the loading and recycling operation, and the banknote withdrawal operation from the loading box 170, and the switching mechanism at the junction is a bi-directional switching mechanism.

When the banknote is determined to be unqualified, the corresponding switching member is controlled to communicate the first passage 221 with the recycling passage 161, and the banknote is delivered into the recycling box 160 for storage through the first passage 221 and the recycling passage 161. In the above-mentioned loading and recycling process, the loading and recycling efficiency is high because the banknotes move along the first passage 221 and sequentially enter the loading passage 171 or the recycling passage 161 that are in communication with the first passage 221. The banknote processing device 10 according to the present embodiment may also use the loading box 170 as the circulating box 150. That is, when the amount of the banknote in the circulating box 150 is less than a set value, the withdrawal from the circulating box 150 may be stopped and the banknote may be directly withdrawn from the loading box 170, thereby preventing shutdown issues caused by a small amount of banknotes in the circulating box 150, thereby improving the operating efficiency.

In order to secure the user's rights and interests, the banknote processing device 10 may also recycle ignored banknotes into the recycling box 160 for storage.

In the ignored banknotes recycling operation, as shown in FIG. 9 (the arrow and the thick solid line in the figure indicate the moving path of banknotes), the corresponding switching member is controlled to communicate the first banknote outgoing path 241 with the second banknote outgoing path 242, to communicate the second banknote outgoing path 242 with the third path 213, to communicate the second path 212 with the first path 211, to communicate the first path 211 with the third passage 223, to communicate the third passage 223 with the first passage 221, and to communicate the first passage 221 with the recycling passage 161. The banknotes at the outlet 120 are delivered to the identification mechanism 130 through the first banknote outgoing path 241, the second banknote incoming path 232, and the third path 213, and after the banknote information is identified by the identification mechanism 130, the banknotes are delivered into the recycling box 160 for storage through the second path 212, the first path 211, the third passage 223, the first passage 221, and the recycling passage 161.

The banknotes move in a one way direction along a preset direction in the auxiliary passage 220 according to the banknote processing method provided by the present embodiment. In the banknote withdrawal operation, the banknotes do not pass through the junction of the loading passage 171 and the auxiliary passage 220. The banknote passes through the junction of the loading passage 171 and the auxiliary passage 220 only when performed the loading operation, the loading and recycling operation, and the banknote withdrawal operation from the loading box 170. Therefore, the probability of jamming in delivering the banknotes is reduced.
