Technical Field

[0001] The invention belongs to the field of financial machinery and specifically discloses a floating wheel lifting mechanism. Background Art

[0002] Financial institutions have many places where paper media need to be printed. For efficient office work, all-in-one machines are now used. That is, paper media is put into the gate to identify the authenticity of the bill, correct the deviation and print it, and automatically push out the printed bill. Since the bill has extremely high requirements for printing, it must be corrected before printing. Considering the size of the overall equipment, the bill transmission channel is too long, especially before correction, the bill is also transmitted in a pressed state. When it reaches the correction position, due to the long bill, one end has often reached the correction position, and the other end is still pressed. In this state, the bill cannot be corrected, so one end of the pressed bill must be released at this time, so an automatic lifting mechanism needs to be designed. Summary of the invention

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] like Figure 1 As shown, the paper medium will deflect slightly during the transmission process. When entering the next printing module, it must be corrected to ensure that the paper medium is in an absolutely positive position, thereby ensuring the absoluteness of the printing position.

[0024] The floating wheel lifting mechanism is fixed on the mounting body 16. The mounting body can be a bill selling module, a bill selling and accepting integrated machine module, etc. It can also be used in other paper page correction mechanisms. It is a necessary link in the designed correction mechanism. When the paper medium is clamped and transported to the floating wheel position by the floating wheel and the driving wheel opposite to the floating wheel, the system issues an operation instruction when correction is required, and the paper medium needs to be offset left and right. At this time, the motor drives the code disc to rotate, and the U-shaped sensor checks the position of the code disc. When it reaches a certain position, the support frame can be lifted, thereby driving the floating wheel assembly to lift up. At this time, the roller in the floating wheel assembly does not form pressure with the opposite driving wheel, that is, there is a gap between the roller and the driving wheel, ensuring that the paper medium in the channel can be offset left and right. After the left and right position offset operation is completed, the motor drives the code disc to rotate. At this time, the connecting protrusion 12 of the code disc does not lift the support frame, and cooperates with the elastic deformation of the torsion spring to press the floating wheel assembly back. At this time, the paper medium is transported in the channel formed by the roller and the driving wheel row opposite to the roller.

[0025] like Figure 2As shown, the mechanism is provided with a support frame 1, which is used to connect several groups of floating wheel assemblies 2, and the support frame 1 can be lifted up by the connection protrusion 12 of the code disk; considering that our design is mainly used in a bill printing device, and the bill is relatively long, setting a group of floating wheel assemblies is not good for the bill conveying capacity, so two groups of floating wheel assemblies are designed in this technical solution. When it is used in other paper sheet correction systems, one or more groups of floating wheel assemblies can be selected according to actual needs.

[0026] The floating wheel assembly 2 includes two rollers 3, the two rollers 3 are connected by a connecting shaft 4, and the floating wheel assembly 2 is rotatably connected to the support frame 1 through a three-way connecting device 5. Figure 3 As shown, the three-way connecting device 5 includes a connecting body 501 and a body extension end 502, and the three-way connecting device is provided with three pairs of connecting holes, which are roller connecting holes 503, support frame connecting holes 504 and fixed seat connecting holes 505, and the spacing between the two fixed seat connecting holes is greater than the spacing between the two roller connecting holes.

[0027] The roller connection hole 503 and the fixed seat connection hole 505 are located on the connecting body 501, the support frame connection hole 504 is located on the body extension end 502, the connecting shaft 4 passes through the roller connection hole 503, the three-way connecting device 5 is rotatably connected with the support frame 1 through the supporting shaft 6; the three-way connecting device 5 is connected with the fixed seat 8 through the rotating shaft 7, the rotating shaft 7 passes through the fixed seat connection hole 505, so that the two ends of the rotating shaft 7 extend out of the fixed seat connection hole 505 and are movably connected with the fixed seat 8, the fixed seat is fixed on the installation body, and the floating wheel lifting mechanism is fixed to the installation body through the fixed seat, the roller connection hole 503 and the support frame connection hole 504 are located on the same plane as the connecting body 501, and the connecting body 501 and the body extension end 502 form an angle, and the angle formed by the connecting body 501 and the body extension end 502 is between 120° and 140°. The connecting shaft 4, the supporting shaft 6 and the rotating shaft 7 are parallel to each other.

[0028] A torsion spring 9 is provided at the lower end of the support frame 1 , and the torsion spring 9 is sleeved on the rotating shaft 7 .

[0029] A driving wheel (not shown in the figure) is arranged opposite to the roller, and the paper medium (not shown in the figure) is located between the roller and the driving wheel.

[0030] like Figure 1-Figure 5As shown, the floating wheel lifting mechanism also includes a driving device, which is driven by a motor 10, and the motor 10 is provided with a code disk 11, and a connecting protrusion 12 is provided on the code disk. A sensor is provided above the code disk 11, and the sensor is a U-shaped sensor 13 for detecting the position of the code disk. The code disk includes a special-shaped baffle 17 and a connecting protrusion 12, and the special-shaped baffle is in a bow-tie shape. The driving device is not limited to motor drive, and can also be any one of hydraulic drive, cylinder drive, electromagnet, and commutator.

[0031] The support frame 1 is a bending structure, one end of the support frame 1 is movably connected to a group of floating wheel assemblies through a support shaft 6, and the other end is in contact with a connecting protrusion 12 of a driving code disk, and another group of floating wheel assemblies 2 is movably connected to the support frame 1 at a bending point 14 through the support shaft 6. The angle at the bending point is between 140° and 160°. The two groups of floating wheel assemblies are parallel to each other, and through the connection of the support frame, it is ensured that the gap between the two groups of floating wheels and the driving wheel is consistent under the top action of the code disk, and the gap designed in the present invention is less than 1mm.

[0032] A groove 15 is provided between the two support frame connection holes, one end of the torsion spring 9 is overlapped in the groove 15, and the other end of the torsion spring is overlapped on the mounting body 16. When the connection protrusion 12 of the code disc does not support the support frame, the three-way connection device moves back toward the mounting body under the action of the torsion spring rebound force, driving the roller to move back toward the mounting body, thereby realizing the roller pressing the driving wheel, that is, realizing the pressing of the paper medium, so that the driving wheel has the function of transporting.

[0033] The motor 10 drives the code disc 11 to follow the motor rotation position changes in the U-shaped sensor 13. The U-shaped sensor lifts the support frame 1 in the floating wheel assembly 2 when it is in the blocking state. Due to the function of the support shaft 6, the three-way connecting device 5 is driven to rotate along the rotating shaft 7. At this time, the roller 3 penetrated by the connecting shaft 4 is deflected at an angle and does not press the paper medium under the roller. The motor 10 drives the code disc 11 to follow the motor rotation position changes in the U-shaped sensor 13, such as Figure 4 In order to not block the U-shaped sensor 13, the torsion spring 9, under the action of the rebound force, causes the support frame 1 in the floating wheel assembly 2 to fall back, causing the roller 3 to deflect back and press the paper medium in the channel again, so that it has the transportation function.

[0034] This design drives the connection protrusion 12 on the code disc through a motor, further driving the floating wheel assembly 2 to rotate with the support shaft 6 as the rotation point, and under the action of the three-phase connection device, the roller is driven away from the installation body, so that a gap is generated between the roller and the driving wheel, so that the driving wheel does not have the function of transporting paper media, so that the paper media in the channel can be adjusted in position or deflected in angle. After the code disc rotates a certain angle again, the connection protrusion 12 part no longer supports the support frame, and the floating wheel assembly falls back due to the action of the torsion spring, so that it has the function of transporting paper media, and the paper media can be transported at this time.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
