Description

Technical Field

[0001] The present invention relates to the technical field of deviation correction mechanisms, and in particular to a fast deviation correction transmission mechanism and a deviation correction method for thin-sheet media. Background Art

[0002] In existing automated sheet media processing devices, such as cash recyclers, financial bill issuance and recovery devices, special printers, special scanners, etc., the media will move quickly in a long channel and will inevitably deviate, making it impossible for the bill to remain parallel to the channel, causing the bill image to easily deform when scanned, and the bill cannot be accurately aligned when printed.

[0003] The traditional solution to the problem of sheet media being easily deflected during transmission is to design a push plate on each side of the channel, and clamp the two push plates together to center the media. To use this method to correct the deviation, the media size must be uniform, or the size of the media entering the channel must be known in advance, because the push plate's travel distance to the center is fixed. If the media size is small, it cannot be pushed into place and correction cannot be completed. If the media size is large, the push plate will squeeze the media, causing damage to the media.

[0004] The problem of how to not be restricted by the medium size and correct the deviation quickly needs further improvement. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a fast deviation-correcting transmission mechanism and a deviation-correcting method for sheet media.

[0008] The transmission assembly includes a channel driving wheel and a channel driven wheel, the channel driving wheel and the channel driven wheel clamp the sheet medium and rotate relative to each other, so that the sheet medium moves forward and backward in the deviation correction mechanism.

[0009] The deflection correction component includes a deflection correction driving wheel and a deflection correction driven wheel. When the channel driving wheel is separated from the channel driven wheel, the deflection correction driving wheel and the deflection correction driven wheel clamp the sheet medium and rotate relatively, so that the sheet medium moves left and right in the deflection correction mechanism.

[0010] Furthermore, the deviation-correcting active wheel is an eccentric wheel.

The lifting assembly includes a motor, a camshaft, a plurality of cams, a plurality of clamping plates and a plurality of baffle sliders. The output shaft of the motor is connected to the camshaft. One end of the camshaft is sleeved with the cam. The cam extends into the clamping plate and contacts the clamping plate. The clamping plate is movably connected to the baffle slider. The baffle slider is embedded in the deviation rectifying lower channel assembly.

[0017] Further, an induction sheet is fixed to the other end of the camshaft. The induction sheet is used to trigger a photoelectric switch.

[0018] The present invention according to the above solution is characterized in that a plurality of photoelectric switches are further provided in the deviation rectifying mechanism. The photoelectric switches are connected to a deviation rectifying control circuit board.

Then the deviation correction motor controls the deviation correction wheel to rotate counterclockwise, and the sheet-like medium moves to the right until the right photoelectric switch in the deviation correction area detects that the sheet-like medium is right-aligned, and the deviation correction work stops.

[0035] The present invention will be further described below in conjunction with the accompanying drawings and the implementation mode:

[0036] It should be noted that the thin sheet media referred to in this application include but are not limited to the commonly used thin sheet media at present, such as: bills of exchange, promissory notes, checks, deposit certificates, etc., and it can be understood that the material of the thin sheet media is paper. Therefore, the deviation correction mechanism of this application can also be used to process other paper items made of paper materials, such as cards or banknotes.

[0037] As Figures 1 to 5 shown, a rapid deviation correction transmission mechanism for thin sheet media includes a deviation correction component and a transmission component.

[0038] The transmission component includes a channel driving wheel 141, a channel driven wheel 142, a plurality of driving wheels 143, a plurality of driving rods 144 and a plurality of transmission belts 145. A number of rows of channel driving wheels 141 are arranged on the deviation correction lower channel component 120. The channel driving wheel 141 is sleeved on the driving rod 144. One end of the driving rod 144 is connected to the driving wheel 143. Adjacent two driving wheels 143 are connected by a transmission belt 145 to drive the channel driving wheel 141 to rotate. A channel driven wheel 142 corresponding to the position of the channel driving wheel 141 is arranged on the deviation correction upper channel component 110. Driven by the motor, the channel driving wheel 141 and the channel driven wheel 142 are in contact and rotate relative to each other, thereby driving the thin sheet media to move back and forth in the transmission channel.

[0039] The deviation correction component includes a deviation correction driving wheel 151, a deviation correction driven wheel 152, a deviation correction motor 153 and a deviation correction gear. The deviation correction driving wheel 151 is arranged in the deviation correction upper channel component 110. The output shaft of the deviation correction motor 153 is connected to the deviation correction gear. The deviation correction gear is connected to the deviation correction driving wheel 151. The deviation correction driven wheel 152 is arranged in the deviation correction lower channel component 120 and corresponds to the position of the deviation correction driving wheel 151.

[0040] Preferably, the deviation rectifying driving wheel 151 is an eccentric wheel. Driven by the deviation rectifying motor 153, when the long end of the deviation rectifying driving wheel 151 contacts the deviation rectifying driven wheel 152 and rotates relatively, it can drive the thin sheet-like medium to move left and right in the transmission channel.

[0041] The deviation rectifying gear also meshes with the upper and lower transmission gears 156. The upper and lower transmission gears 156 are sleeved on the upper and lower transmission rods 157. The end of the upper and lower transmission rods 157 is provided with a cutting edge, and this cutting edge is connected to the driving rod 159 through the lifting rod 158. The channel driven wheel 142 is sleeved on the driving rod 159. When the deviation rectifying motor 153 rotates, it drives the upper and lower transmission gears 156 to rotate, and then drives the upper and lower transmission rods 157 to rotate. Since the upper and lower transmission rods 157 are provided with cutting edges, during their rotation, the upper and lower transmission rods 157 can drive the lifting rod 158 to lift or press down. When the lifting rod 158 lifts, the channel driving wheel 141 is separated from the channel driven wheel 142, and the thin sheet-like medium will not move.

[0042] Preferably, the deviation rectifying gear includes a first deviation rectifying gear 154 and a second deviation rectifying gear 155. The first deviation rectifying gear 154 is connected to the output shaft of the deviation rectifying motor 153. The first deviation rectifying gear 154 meshes with the second deviation rectifying gear 155 through an intermediate gear. The second deviation rectifying gear 155 is coaxially fixed with the deviation rectifying driving wheel 151. The second deviation rectifying gear 155 meshes with the upper and lower transmission gears 156 through another intermediate gear.

[0043] In the present invention, the deviation rectifying upper channel assembly 110 is located above the deviation rectifying lower channel assembly 120 and is hinged to the deviation rectifying lower channel assembly 120. And a transmission channel for the thin sheet-like medium to move is formed between the deviation rectifying upper channel assembly 110 and the deviation rectifying lower channel assembly 120. The detachable cover structure design is convenient for users to use and maintain.

[0044] Preferably, a female gold finger socket 111 is provided on the side of the deviation rectifying upper channel assembly 110, and a male gold finger socket 121 is provided on the side of the deviation rectifying lower channel assembly 120. The female gold finger socket 111 is in contact connection with the male gold finger socket 121 to realize the signal transmission between the deviation rectifying upper channel assembly 110 and the deviation rectifying lower channel assembly 120.

[0045] Corresponding alignment photoelectric switches are respectively arranged on the left and right sides of the deviation rectifying upper channel assembly 110 and the deviation rectifying lower channel assembly 120, and positioning photoelectric switches are respectively arranged on the front and rear ends of the deviation rectifying upper channel assembly 110 and the deviation rectifying lower channel assembly 120. A plurality of photoelectric switches 131 are connected to the deviation rectifying control circuit board. After the photoelectric switches 131 cooperate with each other to determine that the thin sheet-like medium completely enters the deviation rectifying area, the deviation rectifying motor 153 drives the deviation rectifying gear to rotate, so that the deviation rectifying assembly starts to work and adjusts the position of the thin sheet-like medium in the transmission channel. This makes the transmission of the thin sheet-like medium more accurate and stable.

[0046] On one side of the deviation rectification lower channel assembly 120, a lifting assembly is provided. The lifting assembly includes a motor 161, a camshaft 165, a plurality of cams 166, a plurality of clamping plates 167, and a plurality of baffle sliders 168. The output shaft of the motor 161 is connected to a driving wheel 162. The driving wheel 162 meshes with a first gear 163. The first gear 163 meshes with a second gear 164. Both the second gear 164 and the cam 166 are sleeved on one end of the camshaft 165. The cam 166 extends into the clamping plate 167 and contacts the clamping plate 167. The clamping plate 167 is movably connected to the baffle slider 168. The baffle slider 168 is embedded in the deviation rectification lower channel assembly 120. Driven by the motor 161, the cam 166 causes the baffle slider 168 to rise or fall.

[0047] Preferably, an induction sheet is further fixed to the other end of the camshaft 165. The induction sheet is used to trigger a photoelectric switch so as to judge the position of the baffle slider 168.

[0048] The deviation rectification mechanism 100 in the present invention can be applied to document automation devices such as financial bill processing devices, printers, scanners, etc., and mainly rectifies thin sheet-like media moving in a transmission channel.

[0049] A method for quickly rectifying thin sheet-like media includes the following steps:

[0050] Step 1: The photoelectric switch detects the position of the thin sheet-like media;

[0051] Step 2: The control circuit controls the deviation rectification motor to perform the deviation rectification work of the thin sheet-like media according to the detection information of the photoelectric switch. In Step 2, when it is detected that the position of the thin sheet-like media in the deviation rectification area is deviated, the deviation rectification motor controls the deviation rectification wheel to rotate clockwise, and the thin sheet-like media moves to the left until the left photoelectric switch in the deviation rectification area detects that the thin sheet-like media is left-aligned. The deviation rectification motor controls the deviation rectification wheel to rotate counterclockwise, and the thin sheet-like media moves to the right until the right photoelectric switch in the deviation rectification area detects that the thin sheet-like media is right-aligned, and then the deviation rectification work stops.

[0052] The specific deviation rectification process of the present invention (taking the forward movement of the thin sheet-like media in the deviation rectification transmission mechanism as an example):

[0053] After the sheet medium reaches the deflection correction area, the deflection correction motor 153 drives the deflection correction gear to rotate, so that the deflection correction active wheel 151 rotates clockwise, the upper and lower transmission gears 156 drive the upper and lower transmission rods 157 to rotate, the lifting rod 158 rises, the channel driven wheel 142 is separated from the channel driving wheel 141, and the sheet medium is not clamped, so the medium will not move forward. At this time, since the deflection correction active wheel 151 is an eccentric wheel, the long end of the deflection correction active wheel 151 just rubs the sheet medium downward, and the relative rotation of the deflection correction active wheel 151 and the deflection correction driven wheel 152 drives the sheet medium to move to the left; the deflection correction gear continues to rotate, the lifting rod 158 descends, the channel driven wheel 142 contacts the channel driving wheel 141, the sheet medium is clamped, and thus moves forward, but at this time, the short end of the deflection correction active wheel 151 passes by and will not rub the sheet medium, so it will not move to the left or right, thereby preventing the medium from being wrinkled. In this way, the sheet medium will be pushed to the left edge of the transmission channel. When the two left-aligned photoelectric switches sense the arrival of the sheet medium, it means that the sheet medium is parallel to the transmission channel on the left. After aligning to the left, the baffle slider 168 in the lifting assembly rises, and the correction assembly will rub the sheet medium to the right, so that the sheet medium moves to the right and stops at the baffle slider 168. When the two right-aligned photoelectric switches sense the arrival of the sheet medium, it means that the sheet medium is also on the right side of the transmission channel, and the correction action is completed. After the correction action is completed, the lifting assembly will descend to ensure that there is no obstruction when the sheet medium returns.

[0054] The present invention gently pushes the medium left and right under the action of the correcting wheel driving wheel and the correcting driven wheel 152, so that the medium will not be wrinkled during the movement, and the medium is quickly corrected and finally moves parallel to the transmission channel, while not advancing along the two sides of the transmission channel.

[0055] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.

[0056] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
