Please refer to FIGS. 3 to 4. In one embodiment, the temporary storage device 3 has an entrance 302 for the medium to enter and exit. The temporary storage device 3 further includes a mounting frame 31, a first rotation mechanism 32, a second rotation mechanism 33, and a driving mechanism. 34. The tape 35, the guide mechanism 36, and the conveyance mechanism 37. The first rotating mechanism 32, the second rotating mechanism 33, and the driving mechanism 34 are all mounted on the mounting frame 31 and connected to the controller 7. One end of the tape 35 is connected to the first rotating mechanism 32, and the other end is connected to On the second rotation mechanism 33, the first rotation mechanism 32 is used for retracting the winding tape 35, and the second rotation mechanism 33 is used for retracting the winding medium and the winding tape 35. The driving mechanism 34 is connected to the first rotating mechanism 32 and the second rotating mechanism 33 to realize active rotation of the first rotating mechanism 32 and the second rotating mechanism 33. The driving mechanism 34 is also connected to the conveying mechanism 37 to provide the conveying mechanism 37. Power to achieve the transmission of the medium. The conveying mechanism 37 provides power to realize the transmission of the medium.

As shown in FIG. 3, the guide mechanism 36 is rotatably provided on the mounting frame 31, and includes an upper guide plate 361 and a lower guide plate 362, and the upper guide plate 361 and the lower guide plate 362 are substantially arc-shaped for The obstacle is introduced around the second rotation mechanism 33 or led out from the second rotation mechanism 33. The upper guide plate 361 is provided on a side close to the first rotation mechanism 32, and the lower guide plate 362 is provided on a side close to the second rotation mechanism 33. One end of the upper guide plate 361 and the lower guide plate 362 is respectively connected to a rotating shaft fixed to the mounting frame 31, and the other ends thereof are respectively in contact with the second rotation mechanism 33. The upper guide plate 361 and the lower guide plate 362 are configured as a conveying channel 304, and a conveying mechanism 37 is installed on the upper guide plate 361 and / or the lower guide plate 362, respectively, for conveying banknotes located in the conveying channel 304. Portions of the upper guide plate 361 and the lower guide plate 362 near the rotating shaft of the mounting frame 31 form an entrance 302. The middle part of the upper guide plate 361 has a through hole, and the tape 35 on the first rotation mechanism 32 passes through the through hole of the upper guide plate 361 and passes through a part of the transmission channel 304 near the second rotation mechanism 33 and is wound to the second rotation. The contact points of the mechanism 33, the upper guide plate 361 and the second rotation mechanism 33, and the contact points of the lower guide plate 362 and the second rotation mechanism 33 are located on both sides of the connection point of the tape 35 and the second rotation mechanism 33, respectively.

The upper guide plate 361 presses the medium wound on the second rotating mechanism 33, and the lower guide plate 362 plays a role of separating the medium from the second rotating mechanism 33 when the medium is discharged.

When depositing money, the controller 7 controls the second rotating mechanism 33 to take up the reel 35, and the first rotating mechanism 32 to unwind the reel 35. The medium enters the temporary storage device 3 through the entrance 302, and is shared by the conveying mechanism 37 and the guide mechanism 36. Under the action, the medium moves toward the second rotating mechanism 33 along the conveying channel 304. When the medium moves to the contact point between the reel 35 and the second rotating mechanism 33, the reel 35 will wind the medium together on the second rotating mechanism 33. . When the banknote is discharged, the controller 7 controls the first rotation mechanism 32 to take up the reel 35, the second rotation mechanism 33 to unwind the reel 35, and the lower guide plate 362 separates the medium from the second rotation mechanism 33, and then conveys it through the conveying mechanism 37. The medium is sent out of the temporary storage device 3 from the entrance 302 along the transmission channel 304. Regardless of whether it is in the process of depositing money or out of the process, although the thickness of the roll 35 and the medium wound on the second rotating mechanism 33 may change, the end of the upper guide plate 361 and the lower guide plate The end of 362 is always in close contact with the web 35 and the media. In the side sectional view shown in FIG. 3, the unwinding direction of the first rotation mechanism 32 and the winding direction of the second rotation mechanism 33 are counterclockwise, and the winding direction of the first rotation mechanism 32 and the second rotation mechanism 33 The unwinding direction is clockwise; it is obvious that the unwinding and unwinding directions of the first rotating mechanism 32 and the second rotating mechanism 33 are opposite directions when viewed from the other side opposite to FIG. 3.

In this embodiment, the transmission channel 304 is located above the second rotation mechanism 33, so that the guide mechanism 36 can keep in close contact with the winding belt 35 wound on the second rotation mechanism 33 under the effect of its own gravity to transfer the medium Pressing on the second rotating mechanism 33 prevents the media from being jammed due to loose, inclined or overlapping media. In addition, due to the close contact between the end of the lower guide plate 362 and the winding belt 35 wound around the second rotating mechanism 33 when the banknote is discharged, the medium can be smoothly separated from the second rotating mechanism 33 and the probability of banknote jam is reduced.

It can be understood that, in other embodiments, the relative positional relationship between the first rotation mechanism 32, the second rotation mechanism 33, and the transmission channel 304 may also be in other forms. For example, the first rotation mechanism 32 and the transmission channel 304 are both Located below the second rotation mechanism 33 and the like.

The temporary storage device 3 also includes a tensioning mechanism 38 connected to the guide mechanism 36. The tensioning mechanism 38 is used to tension the belt 35, so that the belt 35 can always be in a tensioned state during the process of depositing and discharging banknotes. Therefore, it is possible to ensure that the diameter of the winding belt 35 wound on the first rotating mechanism 32 and the second rotating mechanism 33 is as small as possible, so as to reduce the rate of banknote jamming and improve reliability.

During the process of depositing and dispensing banknotes, due to worn-out banknotes and other reasons, when the medium stored on the surface of the second rotating mechanism 33 needs to be output, there may be a medium remaining on the surface of the drum, so that it enters the storage box 6 or the output port 14 The quantity of media does not match the actual quantity required. Therefore, it is necessary to provide a medium residual detection structure in the temporary storage device 3.

The first rotation mechanism 32 of the present application has a reel structure, and the second rotation mechanism 33 has a roller group structure. As shown in FIG. 5 to FIG. 12, the medium residual detection structure provided in the present application includes a first detection sensor 8 and a roller group, and the roller group includes a first roller 331 and a second coaxially disposed on both sides of the first roller 331. The roller 332 and the third roller 337. The first end surface 3316 of the first roller 331 is provided with a plurality of first roller columns 3313 extending along the axial direction of the first roller 331. The second end surface 3317 of the first roller 331 is provided along the first A plurality of second roller columns 3314 extending axially of a roller 331. The first roller columns 3313 and the second roller columns 3314 are arranged symmetrically, and are formed between the adjacent first roller columns 3313 and the adjacent second roller columns 3314. A detection space for the first detection signal 83 of the first detection sensor 8 to pass through. For ease of understanding, the first detection signal 83 is illustrated in the figure.

In this embodiment, in order to simplify the processing and installation process, the first roller 331 is integrally formed with the first roller column 3313 and the second roller column 3314. In this way, the symmetrical accuracy of the first roller column 3313 and the second roller column 3314 can also be improved, and the detection accuracy of the medium residual detection structure can be improved.

In an embodiment, as shown in FIGS. 5 to 7, the first detection sensor 8 includes a transmitting portion 81 and a receiving portion 82 provided on the mounting frame 31. Specifically, the mounting frame 31 includes a first side plate 311, a first The two side plates 312, the first cross plate 313, and the second cross plate 314. The first side plate 311 is opposite to the second side plate 312. The first cross plate 313 and the second cross plate 314 are connected to the first side plate 311 and Between the second side plates 312, the first cross plate 313 is located above the second cross plate 314, and the rotation shaft 333 is rotatably connected to the rotation shaft 333 between the first side plate 311 and the second side plate 312, and is located on the first cross plate. 313 and the second horizontal plate 314. The first detection signal 83 transmitted by the transmitting section 81 can be received by the receiving section 82 through the detection space. When the first detection signal 83 of the first detection sensor 8 is received by the receiving section 82, it outputs a high level to the controller 7. When the first detection signal 83 of the first detection sensor 8 is not received by the receiving unit 82, it outputs a low level.

Preferably, in order to further improve the detection accuracy of the medium residue, the medium residue detection structure includes two sets of first detection sensors 8, and the first detection signals 83 of a set of the first detection sensors 8 may be between adjacent first roller columns 3313. The formed detection space passes, and the first detection signal 83 of the other set of first detection sensors 8 can pass through the detection space formed between the adjacent second roller columns 3314. By setting two sets of the first detection sensors 8, when any one of the sets fails, the other set can continue to work without affecting the normal operation of the medium residual detection structure. Moreover, two sets of the first detection sensors 8 working at the same time can improve the detection accuracy and avoid misjudgment due to the influence of processing and assembly errors.

Since the first detection signal 83 of the first detection sensor 8 may be blocked by the first roller column 3313 and the second roller column 3314, in order to further improve the detection accuracy of the medium residual detection structure, the medium residual detection structure further includes a second detection sensor 9, The second detection sensor 9 is used to detect whether the first detection signal 83 passes through the detection space.

Specifically, in an embodiment, as shown in FIG. 7, the medium residual detection structure further includes a light-shielding portion 3371, and the light-shielding portion 3371 is provided on the roller group in a one-to-one correspondence with the first roller column 3313 and the second roller column 3314. The light shielding portion 3371 has a predetermined phase difference from the first roller column 3313 and the second roller column 3314. The light shielding portion 3371 has a certain width in the circumferential direction. The light shielding portion 3371 rotates with the roller group, so that the light shielding portion 3371 blocks the second detection. When the second detection signal of the sensor 9 is used, the first detection signal 83 of the first detection sensor 8 is not blocked by the first roller column 3313 and the second roller column 3314 and can pass through the detection space.

In this embodiment, the light shielding portion 3371 is disposed on an end of the third roller 337 away from the first roller 331. The second detection sensor 9 is a U-shaped sensor. The U-shaped sensor includes a main body 91 and a U-shaped groove 92. The main body 91 is provided. On the second side plate 312, a U-shaped groove 92 is provided toward the third roller 337. The plurality of light shielding portions 3371 selectively enter the U-shaped groove 92 as the third roller 337 rotates, so that one of the plurality of light shielding portions 3371 blocks the second detection signal.

When the light blocking portion 3371 does not block the second detection signal, the second detection sensor 9 outputs a high level. When the light blocking portion 3371 blocks the second detection signal, the second detection sensor 9 outputs a low level. The level signal output from the sensor 9 determines whether the first detection signal 83 of the first detection sensor 8 is blocked by the first roller column 3313 and the second roller column 3314.

It can be known from the above that when the first detection signal 83 sent from the transmitting section 81 of the first detection sensor 8 is received by the receiving section 82 and outputs a high level, it can be determined that there are no banknotes remaining on the drum group. When the first detection signal 83 from the transmitting section 81 of the first detection sensor 8 is not received by the receiving section 82 and outputs a low level, if the second detection signal of the second detection sensor 9 is not blocked by the light shielding section 3371, the output is high.
