Description

[0001] The present application claims priority to Chinese Patent Application No. 202311315581.3, filed with the China National Intellectual Property Administration (CNIPA) on Oct. 11, 2023, the disclosure of which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] The present application relates to the technical field of financial apparatuses, for example, a banknote feeding device, a cash recycling apparatus, and a banknote feeding method.BACKGROUND

[0003] The cash recycling apparatus is a financial self-service apparatus integrating multiple functions, including cash recycling, deposit, withdrawal, sorting, counting, authenticity verification, continuous uninterrupted banknote feeding, and overnight cash storage. The existing cash recycling apparatus generally includes a banknote feeding device configured to feed banknotes one by one into the device. For example, the Chinese Patent CN208126501U discloses a banknote feeding device, and the banknote feeding device includes a support plate, a banknote kicking roller, a banknote separating roller, and a banknote blocking roller. The support plate is configured to support the banknotes. The banknote kicking roller and the banknote separating roller are sequentially arranged on the support plate in a banknote feeding direction. The banknote blocking roller is disposed above the support plate and opposite to the banknote separating roller. A banknote inlet is formed between the banknote blocking roller and the banknote separating roller. During banknote feeding, the banknote kicking roller rotates and drives banknotes in contact therewith to move toward the banknote inlet. When the banknotes move between the banknote separating roller and the banknote blocking roller, the banknote separating roller rotates to drive banknotes in contact therewith to move, while the banknote blocking roller remains stationary. As a result, banknotes in contact with the banknote separating roller continue to move under the drive of the banknote separating roller, and other banknotes not in contact with the banknote separating roller are blocked by the banknote blocking roller, so that only the single banknote in contact with the banknote separating roller is separated and fed.

[0004] However, when a stack of banknotes placed by the user on the support plate is stacked unevenly in the banknote feeding direction, a banknote that first contacts the banknote kicking roller may be a second banknote located above the lowermost first banknote, rather than the lowermost first banknote. In this case, when the banknote kicking roller rotates, it first drives the second banknote in contact therewith between the banknote separating roller and the banknote blocking roller. When the first banknote moves under the friction of the second banknote and comes into contact with the banknote kicking roller, the banknote kicking roller drives the first banknote toward the banknote separating roller and the banknote blocking roller, resulting in two banknotes jamming at the banknote separating roller and the banknote blocking roller.SUMMARY

[0005] The present application provides a banknote feeding device, a cash recycling apparatus, and a banknote feeding method. The banknote feeding device can solve the problem of banknote jamming and improve the reliability of banknote feeding.

[0006] In a first aspect, the present application provides a banknote feeding device. The banknote feeding device includes a frame, a first banknote kicking roller, a second banknote kicking roller, a banknote separating roller, a banknote blocking portion, and a banknote supporting member. The first banknote kicking roller, the second banknote kicking roller, the banknote separating roller, the banknote blocking portion, and the banknote supporting member are disposed on the frame. The frame includes a support portion and a reference portion. The support portion and the reference portion are disposed at an included angle. The support portion is configured to support banknotes. The reference portion is located above the support portion. A banknote inlet is formed between the reference portion and the support portion. The first banknote kicking roller, the second banknote kicking roller, the banknote inlet, and the banknote separating roller are arranged in sequence in a banknote feeding direction. The first banknote kicking roller, the second banknote kicking roller, and the banknote separating roller are each configured to drive banknotes to move. The banknote blocking portion is disposed opposite the banknote separating roller. The banknote supporting member is movably connected to the frame, is movable relative to the frame, and has a working position and an avoidance position. In a case where the banknote supporting member is in the working position, the banknote supporting member is capable of supporting banknotes so that banknotes are driven by the first banknote kicking roller to align along the reference portion. In a case where the banknote supporting member is in the avoidance position, the first banknote kicking roller and the second banknote kicking roller are capable of jointly driving banknotes to enter a space between the banknote separating roller and the banknote blocking portion via the banknote inlet.

[0007] In a second aspect, the present application provides a cash recycling apparatus including the banknote feeding device of any one of the previous embodiments.

[0008] In a third aspect, the present application provides a banknote feeding method applied to the banknote feeding device described above. The banknote feeding method includes that: the banknote supporting member is controlled to move to the working position in a case where a set condition is satisfied; in response to detecting that banknotes exist on the support portion, the first banknote kicking roller is controlled to rotate for a set time, to drive banknotes placed on the support portion to align along the reference portion; the banknote supporting member is controlled to move to the avoidance position; and the first banknote kicking roller, the second banknote kicking roller and the banknote separating roller are controlled to rotate to enable the second banknote kicking roller to drive banknotes in contact with the second banknote kicking roller to enter a space between the banknote separating roller and the banknote blocking portion.BRIEF DESCRIPTION OF THE DRAWINGS

The loading cassette 134 is configured to load banknotes into the recycling cassette 132.

[0018] FIG. 2 is a sectional view of a banknote feeding device when a banknote supporting member 700 is in an avoidance position according to an embodiment of the present application. FIG. 3 is a sectional view of a banknote feeding device when a banknote supporting member 700 is in a working position according to an embodiment of the present application.

[0019] With reference to FIGS. 2 and 3, the banknote feeding device 020 in this embodiment includes a frame 200, a first banknote kicking roller 300, a second banknote kicking roller 400, a banknote separating roller 500, a banknote blocking portion 600, and a banknote supporting member 700. The first banknote kicking roller 300, the second banknote kicking roller 400, the banknote separating roller 500, the banknote blocking portion 600, and the banknote supporting member 700 are disposed on the frame 200. The frame 200 includes a support portion 210 and a reference portion 220. The support portion 210 and the reference portion 220 are disposed at an included angle. The support portion 210 is configured to support the banknotes. The reference portion 220 is located above the support portion 210. A banknote inlet 230 is formed between the reference portion 220 and the support portion 210. The first banknote kicking roller 300, the second banknote kicking roller 400, the banknote inlet 230, and the banknote separating roller 500 are arranged in sequence in a banknote feeding direction a. The first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 are each configured to drive the banknotes to move. Part of the first banknote kicking roller 300 and part of the second banknote kicking roller 400 protrude from the support portion 210. The banknote blocking portion 600 is disposed opposite the banknote separating roller 500. The banknote blocking portion 600 and the banknote separating roller 500 cooperate so that: a single banknote in contact with the banknote separating roller 500 can enter between the banknote blocking portion 600 and the banknote separating roller 500 and continue to move under the driving of the banknote separating roller 500, while other banknotes not in contact with the banknote separating roller 500 are blocked by the banknote blocking portion 600 and cannot enter between the banknote blocking portion 600 and the banknote separating roller 500. The banknote supporting member 700 is movably connected to the frame 200. The banknote supporting member 700 is movable relative to the frame 200 and has a working position and an avoidance position. When the banknote supporting member 700 is in the working position, the banknote supporting member 700 is capable of supporting banknotes so that banknotes are driven by the first banknote kicking roller 300 to align along the reference portion 220. When the banknote supporting member 700 is in the avoidance position, the first banknote kicking roller 300 and the second banknote kicking roller 400 are capable of jointly driving the banknotes to enter a space between the banknote separating roller 500 and the banknote blocking portion 600 via the banknote inlet 230. Through cooperation between the banknote supporting member 700 and the reference portion 220, the banknotes can align before entering the banknote inlet 230, thereby solving a problem of banknote jamming between the banknote separating roller 500 and the banknote blocking portion 600 caused by misaligned stacking of multiple banknotes, and improving the reliability of banknote feeding.

[0020] The single banknote is used as an example. When the banknote supporting member 700 is in the working position, a part of a surface of the banknote fed into the banknote feeding device 020 is supported by the banknote supporting member 700, another part of the surface is supported by the support portion 210, and the banknote can be in contact with the first banknote kicking roller 300, so that the banknote align along the reference portion 220 under the driving of the first banknote kicking roller 300. When the banknote supporting member 700 is in the avoidance position, the banknote falls onto the support portion 210, so that the support portion 210 supports the entire surface of the banknote, and the banknote is in contact with the second banknote kicking roller 400. The second banknote kicking roller 400 is capable of driving the banknote to enter between the banknote separating roller 500 and the banknote blocking portion 600 via the banknote inlet 230.

[0021] FIG. 4 is a flowchart of a banknote feeding method according to an embodiment of the present application. With reference to FIG. 4, this embodiment further provides a banknote feeding method. The banknote feeding method is applied to the above-mentioned banknote feeding device 020 and includes steps described below.

[0022] In step S100, the banknote supporting member 700 is controlled to move to the working position in a case where a set condition is satisfied.

[0023] In this embodiment, the set condition means that the banknote feeding device 020 is powered on to perform an initialization process, or that the support portion 210 is detected to change from having banknotes to having no banknotes. With such an arrangement, the banknote supporting member 700 is allowed to move to the working position during the idle period when the banknote feeding device 020 is waiting to perform a banknote feeding operation, so that after the banknote feeding operation is started, the user can directly place the banknotes on the support portion 210 without waiting for the action of the banknote supporting member 700. This not only improves the banknote feeding efficiency, but also improves the reliability of aligning the banknotes along the reference portion 220.

[0024] Optionally, with reference to FIG. 5, the banknote feeding device 020 further includes a first motor 900, a controller 940, and a first detection member 931. The first motor 900 may be drivingly connected to the banknote supporting member 700 to drive the banknote supporting member 700 to move to the working position. In the banknote feeding direction, the first detection member 931 is disposed upstream of the banknote inlet 230 and is communicatively connected to the controller 940. The first detection member 931 is configured to detect whether the banknotes are placed on the support portion 210. Exemplarily, the first detection member 931 is a sensor. When the banknotes are placed on the support portion 210, the first detection member 931 sends a first detection signal to the controller 940. When no banknote exists on the support portion 210, the first detection member 931 sends a second detection signal to the controller 940. When the signal sent by the first detection member 931 changes from the first detection signal to the second detection signal, it is determined that the support portion 210 changes from having banknotes to having no banknotes. When the controller 940 detects that the banknote feeding device 020 is powered on to complete the initialization process, or detects that the support portion 210 changes from having banknotes to having no banknotes, the controller 940 controls the first motor 900 to rotate to drive the banknote supporting member 700 to move to the working position.

[0025] In step S200, in response to detecting that banknotes exist on the support portion 210, the first banknote kicking roller 300 is controlled to rotate for a set time, to drive the banknotes placed on the support portion 210 to align along the reference portion 220.

[0026] Optionally, the banknote feeding device further includes a second motor 950. The second motor 950 is drivingly connected to the first banknote kicking roller 300 and is configured to drive the first banknote kicking roller 300 to rotate. When the controller 940 detects that the signal sent by the first detection member 931 is the first detection signal, the controller 940 determines that the user has placed the banknotes on the support portion 210, and controls the second motor 950 to rotate to drive the first banknote kicking roller 300 to rotate for the set time, thereby driving the banknotes placed on the support portion 210 to align along the reference portion 220.

[0027] In step S300, the banknote supporting member 700 is controlled to move to the avoidance position.

[0028] Optionally, after the first banknote kicking roller 300 rotates for the set time, the controller 940 controls the first motor 900 to rotate to drive the banknote supporting member 700 to move to the avoidance position. Optionally, after the first banknote kicking roller 300 rotates for the set time, the controller 940 first controls the second motor 950 to stop rotating, so that the first banknote kicking roller 300 stops rotating. When the controller 940 detects that the second motor 950 stops rotating, the controller 940 then controls the first motor 900 to rotate to drive the banknote supporting member 700 to move to the avoidance position. With such an arrangement, the first banknote kicking roller 300 will not change the stacking state of the banknotes during the movement of the banknote supporting member 700 from the working position to the avoidance position, thereby ensuring the reliability of banknote feeding.

[0029] In step S400, the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 are controlled to rotate, to drive banknotes in contact with the second banknote kicking roller 400 to enter between the banknote separating roller 500 and the banknote blocking portion 600.

[0030] Optionally, the second motor 950 is also drivingly connected to the second banknote kicking roller 400 and the banknote separating roller 500, and the second motor 950 is configured to drive the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 to rotate synchronously. The step of controlling the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 to rotate includes: the controller 940 controls the second motor 950 to rotate to drive the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 to rotate synchronously. With such an arrangement, the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 are driven by the second motor 950, thereby saving costs.

[0031] In other embodiments, the banknote feeding device 020 includes a second motor 950 and a third motor. The second motor 950 is drivingly connected to the first banknote kicking roller 300 and is configured to drive the first banknote kicking roller 300 to rotate. The third motor is drivingly connected to the second banknote kicking roller 400 and the banknote separating roller 500 and is configured to drive the second banknote kicking roller 400 and the banknote separating roller 500 to rotate synchronously. The step of controlling the first banknote kicking roller 300 to rotate includes: the second motor 950 is controlled to rotate so as to drive the first banknote kicking roller 300 to rotate. The step of controlling the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 to rotate includes: the second motor 950 and the third motor are controlled to rotate to drive the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 to rotate.

[0032] Optionally, the banknote feeding method further includes a step S600 described below.

[0033] In step S600, in response to detecting that the banknotes exist on the support portion 210 but no banknote is detected reaching downstream of the banknote separating roller 500 after the set time, the banknote supporting member 700 is controlled to vibrate to adjust the state of the banknotes.

[0034] Optionally, the banknote feeding device 020 further includes a second detection member 932. The second detection member 932 is communicatively connected to the controller 940. In the banknote feeding direction, the second detection member 932 is located downstream of the banknote separating roller 500 and is configured to detect whether banknotes exist downstream of the banknote separating roller 500. Exemplarily, the second detection member 932 is a sensor. When the banknotes exist downstream of the banknote separating roller 500, the second detection member 932 sends a third detection signal to the controller 940. When no banknote exists downstream of the banknote separating roller 500, the second detection member 932 sends a fourth detection signal to the controller 940. In this embodiment, the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 are controlled to rotate to drive the banknotes in contact with the second banknote kicking roller 400 to enter between the banknote separating roller 500 and the banknote blocking portion 600. In response to detecting that the banknotes exist on the support portion 210 and no banknote is detected reaching downstream of the banknote separating roller 500 after the set time, it means that the banknotes cannot enter between the banknote separating roller 500 and the banknote blocking portion 600 due to an abnormal state of the banknotes; therefore, the banknote supporting member 700 is controlled to vibrate to adjust the state of the banknotes. When the controller 940 receives the first detection signal sent by the first detection member 931 and does not receive the third detection signal sent by the second detection member 932 after a set time interval, it is determined that the banknotes exist on the support portion 210 and no banknotes exist downstream of the banknote separating roller 500, and the controller 940 controls the first motor 900 to rotate so as to drive the banknote supporting member 700 to vibrate.

[0035] In this embodiment, the step of controlling the banknote supporting member 700 to vibrate includes: the banknote supporting member 700 is controlled to move from the avoidance position to the working position for a set number of times. The set number of times may be once, twice, or multiple times, which is not limited in this embodiment. In this way, when the banknotes cannot enter between the banknote separating roller 500 and the banknote blocking portion 600 due to the abnormal state of the banknotes, the state of the banknotes is adjusted by controlling the banknote supporting member 700 to vibrate. For example, the state of the banknotes is adjusted by reducing the interaction force between two adjacent banknotes, reducing the banknote feeding resistance, or adjusting the position of the banknote relative to the banknote separating roller 500, thereby facilitating the second banknote kicking roller 400 to drive the banknotes between the banknote separating roller 500 and the banknote blocking portion 600 and improving the success rate of banknote feeding.

[0036] Optionally, the step of controlling the banknote supporting member 700 to vibrate includes: the banknote supporting member 700 is controlled to move a preset distance from the avoidance position to the working position and then return to the avoidance position, for example, the banknote supporting member 700 moves to an intermediate position between the avoidance position and the working position and then returns to the avoidance position.

[0037] The banknote feeding process of the banknote feeding device 020 in this embodiment is as follows.

[0038] After the banknote feeding device 020 is powered on to perform the initialization process, or after a previous banknote feeding is completed, the controller 940 controls the first motor 900 to rotate, so as to drive the banknote supporting member 700 to move to the working position. When the user places the banknotes on the support portion 210 of the banknote feeding device 020, the controller 940 controls the second motor 950 to rotate, so as to drive the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 to rotate synchronously. The banknote supporting member 700 located in the working position supports the banknotes, so that the first banknote kicking roller 300 can drive the banknote in contact therewith (i.e., a lowermost first banknote in the stacked banknotes) to move in the banknote feeding direction and align along the reference portion 220, so that a front end of the first banknote abuts against the reference portion 220. Since the second banknote kicking roller 400 and the reference portion 220 are arranged sequentially in the banknote feeding direction, the front end of the banknote is located downstream of the second banknote kicking roller 400. Then, the controller 940 controls the second motor 950 to stop rotating, so that the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 stop rotating synchronously. Thereafter, the controller 940 controls the first motor 900 to rotate reversely, so as to drive the banknote supporting member 700 to move to the avoidance position. The controller 940 controls the second motor 950 to rotate, to drive the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 to rotate synchronously. The stacked banknotes fall onto the support portion 210 and are supported by the support portion 210. Since the front end of the first banknote is located downstream of the second banknote kicking roller 400, the first banknote falls onto the second banknote kicking roller 400, that is, a surface of the first banknote can contact the second banknote kicking roller 400. The second banknote kicking roller 400 can drive the first banknote to move toward the banknote inlet 230 and enter between the banknote separating roller 500 and the banknote blocking portion 600 via the banknote inlet 230. In addition, the first banknote kicking roller 300 can drive a second banknote located above the first banknote to move to the second banknote kicking roller 400, and the front end of the second banknote aligns along the banknote blocking portion 600. When the first banknote leaves the banknote separating roller 500 and the banknote blocking portion 600, the second banknote kicking roller 400 can continue to drive the second banknote to enter between the banknote separating roller 500 and the banknote blocking portion 600, and so on. Under the combined driving of the first banknote kicking roller 300 and the second banknote kicking roller 400, the banknotes can be driven one by one from bottom to top to enter between the banknote separating roller 500 and the banknote blocking portion 600 via the banknote inlet 230.

[0039] Optionally, the banknote separating roller 500 includes a first spindle 510 and at least two banknote separating wheels 511 each sleeved on the first spindle 510. The at least two banknote separating wheels 511 are disposed at intervals along an axial direction of the first spindle 510. The banknote blocking portion 600 is a banknote blocking roller. The banknote blocking roller includes a second spindle 610 and multiple banknote blocking wheels 611 sleeved on the second spindle 610. The multiple banknote blocking wheels 611 are disposed at intervals in an axial direction of the second spindle 610. The second spindle 610 and the first spindle 510 are disposed on the frame 200 in a parallel and spaced-apart manner. The banknote blocking wheel 611 is inserted between two adjacent banknote separating wheels 511, and is spaced apart from the two adjacent banknote separating wheels 511 in the axial direction of the first spindle 510. Such an arrangement not only improves the reliability of the banknote blocking roller in preventing overlapped banknotes from entering between the banknote blocking roller and the banknote separating roller 500, but also avoids wear caused by mutual contact between the banknote blocking wheels 611 and the banknote separating wheels 511.

[0040] Of course, in other embodiments, the banknote blocking portion 600 may also be a block-shaped or plate-shaped banknote blocking member.

[0041] In this embodiment, a linear speed of the first banknote kicking roller 300 is configured to be greater than a linear speed of the second banknote kicking roller 400. In this way, when the banknote supporting member 700 is in the avoidance position and the second banknote kicking roller 400 drives the lowermost first banknote to move toward the banknote inlet 230, the first banknote kicking roller 300 can rapidly drive the second banknote located above the first banknote to the second banknote kicking roller 400, so that the second banknote kicking roller 400 drives the second banknote to enter between the banknote separating roller 500 and the banknote blocking portion 600 when the first banknote leaves between the banknote separating roller 500 and the banknote blocking portion 600. That is, the second banknote kicking roller 400 can reliably drive the banknotes to enter one by one from bottom to top between the banknote separating roller 500 and the banknote blocking portion 600 via the banknote inlet 230, thereby further improving the reliability of banknote feeding.

[0042] Optionally, the banknote feeding device 020 further includes a transmission assembly. The first motor 900 is drivingly connected to the first banknote kicking roller 300, the second banknote kicking roller 400, and the banknote separating roller 500 simultaneously through the transmission assembly, and the transmission assembly is configured to make the linear speed of the first banknote kicking roller 300 greater than the linear speed of the second banknote kicking roller 400. The transmission assembly includes, but is not limited to, a gear assembly and a belt transmission assembly.

[0043] With reference to FIGS. 2, 3, and 7, in this embodiment, the frame 200 is provided with a banknote receiving cavity 201. The banknote receiving cavity 201 has a bottom wall and a side wall 203. The bottom wall and the side wall 203 are disposed at an included angle. The bottom wall is configured to form the support portion 210. The reference portion 220 is a reinforcing rib centrally disposed on the side wall 203 in a width direction of the banknote. With such an arrangement, when the folded banknote enters the banknote inlet 230, the reference portion 220 at the middle portion of the side wall 203 can contact the middle portion of the banknote, and the spaces between the side walls 203 on two sides of the reference portion 220 and the support portion 210 are relatively large. Therefore, the folded portion of the banknote can smoothly enter the banknote inlet 230 through the spaces between the two sides of the reference portion 220 and the support portion 210, thereby reducing requirements for the banknotes placed on the support portion 210.

[0044] Optionally, the banknote receiving cavity 201 has a banknote insertion opening 202 configured to insert banknotes into the banknote receiving cavity 201. The banknote insertion opening 202 and the banknote inlet 230 are disposed opposite to and spaced apart from each other in the banknote feeding direction. In this embodiment, the banknote feeding direction is a front-rear direction, and the banknote inlet 230 is disposed opposite to and spaced apart from the banknote insertion opening 202 and is in front of the banknote insertion opening 202. That is, when the banknote supporting member 700 is in the working position, the banknote supporting member 700 can support a front portion surface of the banknote, and the first banknote kicking roller 300 can contact a rear portion surface of the banknote, so that the first banknote kicking roller 300 can drive the banknote to move forward when rotating, and the front end of the banknote abuts against the reference portion 220 under the driving of the first banknote kicking roller 300.

[0045] Optionally, the bottom wall of the banknote receiving cavity 201 is disposed to be inclined downward in the banknote feeding direction. With such an arrangement, the smoothness of movement of the banknotes in the banknote feeding direction is improved.

[0046] With reference to FIGS. 2 and 3, in this embodiment, the support portion 210 has a first support surface 211 configured to support the banknotes. The reference portion 220 includes a reference surface 221 and a guide surface 222. The reference surface 221 and the guide surface 222 are disposed at an included angle. The guide surface 222 is disposed opposite to and spaced apart from the first support surface 211, and the banknote inlet 230 is formed between the guide surface 222 and the first support surface 211. A first end of the banknote supporting member 700 is located below the first support surface 211, and the first end of the banknote supporting member 700 is pivotally connected to the frame 200 through a first pivot shaft 710. The banknote supporting member 700 is rotatable relative to the frame 200 about an axis of the first pivot shaft 710 between the working position and the avoidance position. When the banknote supporting member 700 is in the working position, a second end of the banknote supporting member 700 passes through the first support surface 211 and extends toward the reference surface 221, so that when the first banknote kicking roller 300 drives the banknotes to move along the banknote supporting member 700, front ends of the banknotes can abut against the reference surface 221, that is, the banknotes align along the reference surface 221, and the banknote supporting member 700 shields the banknote inlet 230. When the banknote supporting member 700 is in the avoidance position, the second end of the banknote supporting member 700 does not protrude beyond the first support surface 211, so that the banknote inlet 230 is exposed. In this embodiment, when the banknote supporting member 700 is in the avoidance position, the second end of the banknote supporting member 700 is flush with the first support surface 211 to expose the banknote inlet 230. Of course, in other embodiments, when the banknote supporting member 700 is in the avoidance position, the second end of the banknote supporting member 700 can also be located below the first support surface 211 to expose the banknote inlet 230. With such an arrangement, when the banknote supporting member 700 is in the working position, a part of a surface of the banknote fed into the banknote feeding device 020 is supported by the first support surface 211, and another part of the surface is supported by the banknote supporting member 700. When the first banknote kicking roller 300 drives the banknotes to move, the banknotes can move along the banknote supporting member 700 and abut against the reference surface 221 under guidance of the banknote supporting member 700, so that the banknotes reliably align at the reference surface 221. In this case, the banknote supporting member 700 shields the banknote inlet 230 to prevent the banknotes from entering the banknote inlet 230, thereby improving the reliability of alignment of the banknotes along the reference surface 221 before entering the banknote inlet 230.

[0047] It is to be understood that, in other embodiments, the banknote supporting member 700 can also be configured to be slidably connected to the frame 200. For example, the banknote supporting member 700 is slidable relative to the frame 200 in a vertical direction between the working position and the avoidance position. The banknote supporting member 700 has an inclined surface. When the banknote supporting member 700 is in the working position, a lower end of the inclined surface is connected to the first support surface 211, and an upper end of the inclined surface is disposed adjacent to the reference surface 221. When the banknote is placed into the banknote feeding device 020, a part of a surface of the banknote is supported by the first support surface 211, and another part of the surface of the banknote is supported by the inclined surface. When the first banknote kicking roller 300 rotates, it drives the banknotes to move along the inclined surface and abut against the reference surface 221, so that the banknotes align along the reference surface 221. When the banknote supporting member 700 is in the avoidance position, the upper end of the inclined surface does not protrude beyond the first support surface 211 to expose the banknote inlet 230. The first support surface 211 supports the entire banknote, and rotation of the second banknote kicking roller 400 can drive the banknote to enter between the banknote separating roller 500 and the banknote blocking portion 600 via the banknote inlet 230.

[0048] FIG. 6 is a structural schematic view of the banknote supporting member 700 according to an embodiment of the present application. FIG. 7 is a structural schematic view of a banknote feeding device 020 according to an embodiment of the present application. FIG. 8 is an enlarged view of VIII of FIG. 7.

[0049] With reference to FIGS. 3 to 8, in this embodiment, the banknote supporting member 700 has a second support surface 701 configured to support banknotes and an avoidance groove 702 penetrating through the second support surface 701. When the banknote supporting member 700 is in the working position, the second banknote kicking roller 400 is located below the second support surface 701. When the banknote supporting member 700 is in the avoidance position, part of the second banknote kicking roller 400 passes through the avoidance groove 702 and protrudes above the second support surface 701. With such an arrangement, when the banknote supporting member 700 is in the working position, it is ensured that the second banknote kicking roller 400 does not contact the banknotes, thereby preventing the second banknote kicking roller 400 from driving the banknotes to move; and when the banknote supporting member 700 is in the avoidance position, it is ensured that the second banknote kicking roller 400 can reliably contact the banknotes to reliably drive the banknotes to move toward the banknote inlet 230.

[0050] Optionally, the first pivot shaft 710 is located between the first banknote kicking roller 300 and the second banknote kicking roller 400. With such an arrangement, when the banknote supporting member 700 rotates about the axis of the first pivot shaft 710 between the working position and the avoidance position, the banknote supporting member 700 can reliably shield the second banknote kicking roller 400 or expose the second banknote kicking roller 400. Therefore, when the banknote supporting member 700 is in the working position, the first banknote kicking roller 300 can be utilized to reliably drive the banknote to move and align with the reference surface 221; and when the banknote supporting member 700 is in the avoidance position, both the first banknote kicking roller 300 and the second banknote kicking roller 400 can be utilized to reliably drive the banknote into the banknote inlet 230.

[0051] Optionally, when the banknote supporting member 700 is in the avoidance position, the second support surface 701 is coplanar with the first support surface 211. With such an arrangement, when the banknote supporting member 700 is in the avoidance position, the banknote is supported by both the first support surface 211 and the second support surface 701. This not only improves the stability of supporting the banknote, but also avoids the problem of the hindered banknote movement caused by the height difference between the first support surface 211 and the second support surface 701, thereby ensuring that the banknote can smoothly enter the banknote inlet 230. In other embodiments, when the banknote supporting member 700 is in the avoidance position, the second support surface 701 can also be located below the first support surface 211.

[0052] Optionally, the banknote supporting member 700 is provided with multiple avoidance grooves 702. The second banknote kicking roller 400 includes a third spindle 410 and multiple banknote kicking wheels 411 disposed on the third spindle 410. The multiple banknote kicking wheels 411 are disposed at intervals in an axial extension direction of the third spindle 410. The multiple banknote kicking wheels 411 are inserted into the multiple avoidance grooves 702 in a one-to-one correspondence. With such an arrangement, when the banknote supporting member 700 is in the avoidance position, the multiple banknote kicking wheels 411 can be utilized to reliably drive the banknote into the banknote inlet 230; and when the banknote supporting member 700 is in the working position, the second support surfaces 701 located at two ends of each banknote kicking wheel 411 can support the banknote, thereby preventing the banknote from contacting the banknote kicking wheels 411.

[0053] With reference to FIGS. 6 and 8, in this embodiment, the support portion 210 is provided with an insertion plate 212. When the banknote supporting member 700 moves relative to the frame 200 to the working position or the avoidance position, the insertion plate 212 keeps inserting into the avoidance groove 702. With such an arrangement, the reliability of the overlapping connection between the banknote supporting member 700 and the support portion 210 is improved, and when the banknote supporting member 700 is in either the working position or the avoidance position, the banknote supporting member 700 can prevent the banknote from entering between the support portion 210 and the banknote supporting member 700, thereby ensuring the reliability of the banknote moving from the support portion 210 to the second support surface 701.

[0054] Optionally, the support portion 210 is provided with multiple insertion plates 212, the multiple insertion plates 212 are disposed at intervals in the width direction of the banknote, and the multiple insertion plates 212 are inserted into the multiple avoidance grooves 702 in a one-to-one correspondence. With such an arrangement, when the banknote supporting member 700 is in the working position, the banknote supporting member 700 and the insertion plates 212 can jointly shield the second banknote kicking roller 400, thereby preventing narrow banknotes from contacting the banknote kicking wheels 411 located at two ends among the multiple banknote kicking wheels 411, avoiding the banknote kicking wheels 411 from hindering the movement of the banknote, and reliably guiding the banknote to move to the reference portion 220. Moreover, when the banknote supporting member 700 is in the avoidance position, the multiple insertion plates 212 can guide the banknote to contact the multiple banknote kicking wheels 411 of the second banknote kicking roller 400, thereby ensuring the reliability of the second banknote kicking roller 400 driving the banknote to enter between the banknote separating roller 500 and the banknote blocking portion 600 via the banknote inlet 230.

[0055] With reference to FIGS. 6 and 7, in this embodiment, the banknote supporting member 700 is further provided with an insertion portion 720, and the reference portion 220 is further provided with an insertion groove 223. When the banknote supporting member 700 is in the working position, the insertion portion 720 is inserted into the insertion groove 223 to shield the banknote inlet 230. With such an arrangement, when the banknote supporting member 700 is in the working position, it can prevent the user from directly inserting the banknotes into the banknote inlet 230, thereby ensuring that the banknotes can align along the reference portion 220 before entering the banknote inlet 230.

[0056] Of course, in other embodiments, the reference portion 220 can be provided with the insertion portion 720, and the banknote supporting member 700 can be provided with the insertion groove 223. When the banknote supporting member 700 is in the working position, the insertion portion 720 is inserted into the insertion groove 223 to shield the banknote inlet 230.

[0057] Optionally, the banknote supporting member 700 is provided with multiple insertion portions 720, and the reference portion 220 is provided with multiple insertion grooves 223. When the banknote supporting member 700 is in the working position, the multiple insertion portions 720 are inserted into the multiple insertion grooves 223 in a one-to-one correspondence. With such an arrangement, when the banknote supporting member 700 is in the working position, it can reliably prevent the user from directly inserting banknotes into the banknote inlet 230.

[0058] With reference to FIGS. 3, 6, and 7, in this embodiment, the insertion portion 720 has a third support surface 722 configured to support banknotes. When the banknote supporting member 700 is in the avoidance position, the insertion portion 720 is inserted between two adjacent banknote separating wheels 511, and part of the banknote separating wheel 511 protrudes beyond the third support surface 722. One insertion portion 720 is inserted between every two adjacent banknote separating wheels 511, and the insertion portion 720 is lower than the highest point of the banknote separating wheels 511. With such an arrangement, the banknotes can move smoothly between the banknote separating roller 500 and the banknote blocking portion 600 and can reliably contact the banknote separating roller 500, thereby ensuring reliable driving of the banknotes by the banknote separating roller 500. Optionally, when the banknote supporting member 700 is in the working position, the third support surface 722 is inserted into the insertion groove 223. With such an arrangement, the banknotes can reliably align along the reference portion 220 via the third support surface 722, and moreover, when the banknote supporting member 700 is in the working position, direct insertion of the banknotes into the banknote inlet 230 by the user can be more reliably prevented.

[0059] Optionally, the insertion portion 720 is integrally formed with the banknote supporting member 700, and the third support surface 722 is connected to the second support surface 701. Such arrangement further improves the reliability of the banknotes moving from the second support surface 701 into the space between the banknote separating roller 500 and the banknote blocking portion 600.

[0060] FIG. 9 is an enlarged view of IX of FIG. 2. With reference to FIG. 9, optionally, the support portion 210 further includes multiple limit plates 213. The limit plate 213 is inserted between every two adjacent banknote separating wheels 511, and the limit plate 213 is disposed lower than the highest point of the banknote separating wheel 511. The limit plate 213 is provided with a first limit surface 214, and the insertion portion 720 is provided with a second limit surface 721. When the banknote supporting member 700 is in the avoidance position, the second limit surfaces 721 of the multiple insertion portions 720 are in abutting engagement with the first limit surfaces 214 of the multiple limit plates 213 in a one-to-one correspondence. With such an arrangement, the stability of the banknote supporting member 700 at the avoidance position is improved, and the unsmooth rotation of the banknote separating wheels 511 caused by contact between the insertion portion 720 and the banknote separating wheels 511 is effectively prevented.

[0061] With reference to FIGS. 2 and 3, the banknote feeding device 020 in this embodiment further includes a banknote pressing member 800. The banknote pressing member 800 is disposed opposite the second banknote kicking roller 400 and is configured to press the banknotes toward the second banknote kicking roller 400. The banknote pressing member 800 is movably connected to the frame 200 and is movable relative to the frame 200 to move close to or away from the second banknote kicking roller 400, and the banknote pressing member 800 always has a tendency to move close to the second banknote kicking roller 400. When the banknote supporting member 700 moves toward the working position, the banknote supporting member 700 can be drivingly connected to the banknote pressing member 800; and when the banknote supporting member 700 is drivingly connected to the banknote pressing member 800, the banknote supporting member 700 drives the banknote pressing member 800 to move in a direction away from the second banknote kicking roller 400. When the banknote supporting member 700 moves toward the avoidance position, the driving connection between the banknote supporting member 700 and the banknote pressing member 800 is disengaged, and the banknote pressing member 800 can move close to the second banknote kicking roller 400. With such an arrangement, when the banknote supporting member 700 moves toward the working position, the banknote pressing member 800 can move away from the second banknote kicking roller 400 under the driving of the banknote supporting member 700, thereby facilitating the user to place the banknotes between the banknote supporting member 700 and the banknote pressing member 800. When the banknote supporting member 700 moves to the avoidance position, the driving connection between the banknote supporting member 700 and the banknote pressing member 800 is disengaged, and the banknote pressing member 800 can move toward the second banknote kicking roller 400, thereby pressing the banknotes against the second banknote kicking roller 400. As the number of banknotes on the support portion 210 decreases, the banknote pressing member 800 gradually approaches the second banknote kicking roller 400, so that the banknote pressing member 800 always presses the banknotes tightly, thereby improving friction between the banknotes and the second banknote kicking roller 400, and ensuring that the second banknote kicking roller 400 can reliably drive the banknotes into the banknote inlet 230.

[0062] FIG. 10 is an enlarged view showing a partial structure of a banknote feeding device 020 according to an embodiment of the present application. With reference to FIGS. 3 and 10, optionally, the banknote feeding device 020 further includes a second elastic member 903. The second elastic member 903 is configured to make the banknote pressing member 800 always have a tendency to move close to the second banknote kicking roller 400. That is, when the banknote supporting member 700 moves toward the avoidance position, the driving connection between the banknote supporting member 700 and the banknote pressing member 800 is disengaged, and the banknote pressing member 800 moves toward the second banknote kicking roller 400 under the action of the second elastic member 903, so as to reliably press the banknotes against the second banknote kicking roller 400. As the number of banknotes on the support portion 210 decreases, the banknote pressing member 800 gradually approaches the second banknote kicking roller 400 under the action of the second elastic member 903, thereby ensuring sufficient friction between the banknotes and the second banknote kicking roller 400.

[0063] Of course, in other embodiments, when the banknote supporting member 700 moves toward the avoidance position, the driving connection between the banknote supporting member 700 and the banknote pressing member 800 is disengaged, and the banknote pressing member 800 moves toward the second banknote kicking roller 400 under its own weight. As the number of banknotes on the support portion 210 decreases, the banknote pressing member 800 gradually approaches the second banknote kicking roller 400 under its own weight.

[0064] Optionally, the banknote pressing member 800 is pivotally connected to the frame 200 through a second pivot shaft 810. The second pivot shaft 810 is located on a side of the reference portion 220 facing away from the second banknote kicking roller 400. The banknote pressing member 800 passes through the reference portion 220 and is opposite to the second banknote kicking roller 400. The banknote pressing member 800 is rotatable about an axis of the second pivot shaft 810 to move close to or away from the second banknote kicking roller 400. With such an arrangement, mounting spaces on two sides of the reference portion 220 are rationally utilized, and the structural compactness is improved.

[0065] Optionally, the second pivot shaft 810 is rotatably connected to the frame 200. The banknote pressing member 800 includes a banknote pressing plate 801 and a connection plate 802. The banknote pressing plate 801 is opposite the second banknote kicking roller 400 and is configured to press banknotes toward the second banknote kicking roller 400. A first end of the connection plate 802 is fixedly connected to the second pivot shaft 810 through a fastener, and a second end of the connection plate 802 passes through the reference portion 220 and is fixedly connected to the banknote pressing plate 801 through a fastener. With such an arrangement, the compact structural design can be further ensured.

[0066] Optionally, with reference to FIG. 10, the banknote feeding device 020 further includes a cam 901 and a first elastic member 902. The cam 901 is drivingly connected to the first motor 900, and the cam 901 can be drivingly connected to the banknote supporting member 700. When the first motor 900 drives the cam 901 to rotate, the cam 901 can drive the banknote supporting member 700 to rotate toward the working position. When the banknote supporting member 700 rotates toward the working position, the banknote supporting member 700 can be drivingly connected to the banknote pressing member 800, so that the banknote supporting member 700 can drive the banknote pressing member 800 to rotate in the direction away from the second banknote kicking roller 400. The first elastic member 902 is configured to make the banknote supporting member 700 always have a tendency to rotate toward the avoidance position. That is, when the cam 901 rotates to no longer drive the banknote supporting member 700 to rotate, the banknote supporting member 700 is reset to the avoidance position under the elastic action of the first elastic member 902, to ensure smooth entry of banknotes into the banknote inlet 230.

[0067] FIG. 11 is a schematic structural view of a frame 200 and a banknote pressing member 800 from a first perspective according to an embodiment of the present application. FIG. 12 is a schematic structural view of a frame 200 and a banknote pressing member 800 from a second perspective according to an embodiment of the present application.

[0068] Optionally, with reference to FIGS. 10, 11, and 12, the first pivot shaft 710 is rotatably connected to the frame 200, and the banknote supporting member 700 is fixedly connected to the first pivot shaft 710. The second pivot shaft 810 is rotatably connected to the frame 200, and the banknote pressing member 800 is fixedly connected to the second pivot shaft 810. The banknote feeding device 020 further includes a first transmission member 910 and a second transmission member 920. The first transmission member 910 is fixedly connected to the first pivot shaft 710, and the second transmission member 920 is fixedly connected to the second pivot shaft 810. The first elastic member 902 is connected between the first transmission member 910 and the frame 200, and the second elastic member 903 is connected between the second transmission member 920 and the frame 200. When the first motor 900 drives the cam 901 to rotate, the cam 901 can drive the first transmission member 910 to rotate about the axis of the first pivot shaft 710. The first transmission member 910 drives the banknote supporting member 700 to rotate to the working position via the first pivot shaft 710. Moreover, the first transmission member 910 can drive the second transmission member 920 to rotate about the axis of the second pivot shaft 810. The second transmission member 920 drives the banknote pressing member 800 to move away from the second banknote kicking roller 400 via the second pivot shaft 810.

[0069] Optionally, the first transmission member 910 includes a first transmission plate 911, a first drive shaft 912, and a second drive shaft 913. The first drive shaft 912 and the second drive shaft 913 are fixedly connected to the first transmission plate 911. The first transmission plate 911 is fixedly connected to the first pivot shaft 710. The second transmission member 920 is a second transmission plate. The first drive shaft 912 is configured to abut against the cam 901, and the second drive shaft 913 is configured to abut against the second transmission plate. When the first motor 900 drives the cam 901 to rotate, the cam 901 can abut against the first drive shaft 912 to drive the first transmission plate 911 to drive the banknote supporting member 700 to rotate to the working position. Moreover, the second drive shaft 913 can drive the second transmission plate to rotate about the axis of the second pivot shaft 810, and the second transmission plate drives the banknote pressing member 800 to move away from the second banknote kicking roller 400 via the second pivot shaft 810.

[0070] Optionally, when the first motor 900 drives the cam 901 to rotate by a preset angle, the cam 901 abuts against the first drive shaft 912 so as to drive the first transmission plate 911 to rotate the banknote supporting member 700 to the working position. In other embodiments, the cam 901 can also always abut against the first drive shaft 912, which is not limited herein.

[0071] Optionally, when the banknote supporting member 700 is in the avoidance position, the second drive shaft 913 abuts against the second transmission plate. When the first motor 900 drives the banknote supporting member 700 to rotate toward the working position, the second drive shaft 913 drives the banknote pressing member 800 to move away from the second banknote kicking roller 400 through the second transmission plate. In other embodiments, when the banknote supporting member 700 is in the avoidance position, the second drive shaft 913 is separated from the second transmission plate. When the first motor 900 drives the banknote supporting member 700 to rotate toward the working position by the preset angle, the second drive shaft 913 abuts against the second transmission plate and drives the banknote pressing member 800 to move away from the second banknote kicking roller 400 through the second transmission plate, which is not limited herein.

[0072] During banknote feeding of the banknote feeding device 020 of the cash recycling apparatus in this embodiment, the banknote supporting member 700 moves to the working position. After the user inserts the banknotes into the banknote receiving cavity 201 from the banknote insertion opening 202, the banknote supporting member 700 supports the banknotes. The lowermost first banknote is moved to the reference portion 220 under the action of the first banknote kicking roller 300 and aligns along the reference portion 220. Then, the banknote supporting member 700 is moved to the avoidance position, and the banknotes supported by the banknote supporting member 700 fall onto the second banknote kicking roller 400, so as to ensure that the lowermost first banknote contacts the second banknote kicking roller 400. The first banknote kicking roller 300 and the second banknote kicking roller 400 are used to feed the banknotes one by one into the banknote inlet 230.

[0073] In summary, the banknote feeding device 020 in the present application is used in the cash recycling apparatus 010. Before the user inserts the banknotes into the banknote feeding device, the banknote supporting member is in the working position. After the user inserts the banknotes, the banknote supporting member in the working position supports the banknotes, and the first banknote kicking roller drives the lowermost first banknote to move and align along the reference portion. Then the banknote supporting member is moved to the avoidance position, and the banknotes fall onto the support portion, thereby ensuring that the lowermost first banknote contacts the second banknote kicking roller. When the second banknote kicking roller rotates, the first banknote enters between the banknote separating roller and the banknote blocking portion. Moreover, the first banknote kicking roller can drive the second banknote above the first banknote to move to the second banknote kicking roller, so that when the first banknote leaves between the banknote separating roller and the banknote blocking portion, the second banknote kicking roller can drive the second banknote to enter between the banknote separating roller and the banknote blocking portion. By analogy, under the combined driving of the first banknote kicking roller and the second banknote kicking roller, the banknotes can be driven one by one from bottom to top to enter between the banknote separating roller and the banknote blocking portion via the banknote inlet. In this way, through cooperation between the banknote supporting member and the reference portion, the banknotes can align before entering the banknote inlet, thereby solving the problem of banknote jamming caused by misaligned stacking of multiple banknotes, and improving the reliability of banknote feeding.
