Description

Technical Field

[0001] This application relates to the technical field of printers, and in particular to a paper path, application method, and printer. Background Technology

[0002] With the development of technology and society, self-service printers have emerged. Based on people's daily use, self-service printers are becoming more and more popular and have become an indispensable piece of equipment in schools, public places, commercial departments and government agencies.

[0003] Currently, existing printers require a dedicated paper feed path to export paper from the printer's paper tray, and often need to flip the paper over. The entire flipping process requires multiple sets of paper feed rollers to work together within the paper feed path. The paper is automatically flipped over by these rollers and then moved out of the paper feed path and exported from the printer. During this process, the paper moves out of the paper feed path slowly, resulting in a slow paper export speed for the printer. Therefore, there is an urgent need to develop a paper feed path that can automatically flip and export paper quickly. Summary of the Invention

[0004] In order to develop a paper feed path that can automatically flip and quickly export paper, this application provides a paper feed path, an application method, and a printer.

[0005] The paper path, application method, and printer provided in this application adopt the following technical solution:

[0006] A paper feeding path includes a lower paper feeding path and an upper paper feeding path, the lower paper feeding path and the upper paper feeding path being connected by a bend, and the lower paper feeding path and the upper paper feeding path being arranged parallel to each other; it also includes a blowing mechanism, the blowing mechanism being used to blow paper from the lower paper feeding path through the bend to the upper paper feeding path and blow it out of the upper paper feeding path.

[0007] By adopting the above technical solution, during operation, the paper first enters the lower paper path, and the blowing mechanism feeds the paper from the lower paper path through the bend into the upper paper path and then blows the paper out from the upper paper path. In this process, the lower paper path and the upper paper path are set opposite to each other, thereby realizing the flipping and turning of the paper. In addition, the blowing mechanism can speed up the paper output speed by blowing the paper out of the paper path, thus realizing the purpose of automatically flipping and turning the paper and quickly outputting it from the paper path.

[0008] In one specific implementation, the lower paper path is arranged parallel to the upper paper path.

[0009] By adopting the above technical solution, the paper can be flipped 180 degrees by setting the bottom paper path and the top paper path in parallel.

[0010] In one specific implementation, the blowing mechanism includes a fan assembly, with the fan assemblies arranged opposite to each other on the lower paper path and the upper paper path, and air holes provided near the blowing points of the fan assemblies on both the lower paper path and the upper paper path.

[0011] By adopting the above technical solution, and utilizing two opposing fan groups on the lower and upper paper paths, as well as air holes on the lower and upper paper paths, the fan groups can blow air into the lower and upper paper paths through the air holes during operation, thereby achieving the purpose of blowing and conveying paper.

[0012] In one specific implementation, the fan groups located on the lower paper path blow air towards the bend, and the fan groups located on the upper paper path blow air towards the side away from the bend.

[0013] By adopting the above technical solution, the two fan groups on the lower paper path can blow the paper from the lower paper path to the curve by blowing the air in the same direction as the curve, and the fan groups on the upper paper path can blow the paper in the curve out of the upper paper path by blowing the air in the same direction as the curve.

[0014] In one specific implementation, the fan groups located on the lower paper path have the same air pressure, and the fan groups located on the upper paper path have the same air pressure.

[0015] By adopting the above technical solution, the air pressure of the fan group on the lower paper path is the same as that of the fan group on the upper paper path. Therefore, the air force is in the middle of the lower and upper paper paths, and the lifting force of the air is balanced, so that the paper is in the middle of the lower and upper paper paths during the movement.

[0016] In one specific implementation, a fan controller is also included, and a fan sensor is provided at the entrance of the lower paper path. The fan controller is electrically connected to the fan sensor and the fan assembly.

[0017] By adopting the above technical solution, during operation, the front end of the paper first contacts the fan sensor, the fan sensor sends a signal and transmits the signal to the fan controller. After receiving the signal, the fan controller controls the fan assembly to start working. The fan assembly inflates the paper path downwards and upwards through the air holes, thereby achieving the purpose of the fan assembly blowing the paper. This method does not require manual control and is intelligent and convenient.

[0018] In one specific implementation scheme, a motor is provided on the side of the upper paper path near the bend, and an active roller is coaxially provided on the motor shaft of the motor. A driven roller is also provided in the upper paper path opposite to the active roller, and the surfaces of the active roller and the driven roller abut against each other.

[0019] By adopting the above technical solution, before the paper enters the upper paper path from the curved section, the motor is started. The motor shaft rotates, which drives the active roller to rotate. The driven roller is squeezed on the active roller and is driven to rotate. When the paper enters, it will be sandwiched between the active roller and the driven roller. The active roller and the driven roller carry the paper into the upper paper path, which allows the paper to enter the upper paper path more smoothly.

[0020] In one specific implementation, a motor controller is also included, and a motor sensor is provided on the side of the curve near the upper paper path. The motor controller is electrically connected to both the motor and the motor sensor.

[0021] By adopting the above technical solution, when the front end of the paper comes into contact with the motor sensor, the motor sensor sends a signal and transmits the signal to the motor controller. After receiving the signal, the motor controller controls the motor to start rotating, and the motor drives the active roller to rotate, thereby achieving the purpose of driving the paper into the upper paper path. Moreover, this method does not require manual control and is intelligent and convenient.

[0022] In one application method utilizing the aforementioned paper path, during operation, paper enters the lower paper path and is blown towards one side of the curve by a blowing mechanism. The paper moves along the curve. When the paper enters between the active roller and the driven roller, the active roller and the driven roller drive the paper from the curve into the upper paper path. The paper that has entered the upper paper path is blown out of the upper paper path by the blowing mechanism, and the paper is discharged from the paper path.

[0023] In one specific implementation scheme, during operation, paper enters the lower paper path. When the fan sensor detects the paper, it sends a signal to the fan controller, which then controls the fan assembly to start working. The fan assembly inflates the lower and upper paper paths through air vents, and the paper is blown from the lower paper path into the bend. When the motor sensor detects the paper, it sends a signal to the motor controller, which then controls the motor to start rotating. The motor drives the active roller to rotate, and the driven roller is pressed against the active roller by gravity. The paper is sandwiched between the active and driven rollers, and the active and driven rollers carry the paper into the upper paper path, thus completing a 180-degree flip of the paper. After entering the upper paper path, the paper is inflated by the fan assembly and blown out of the upper paper path, thus exiting the paper path.

[0024] In one specific implementation scheme, during operation, the paper enters the lower paper path horizontally. As the paper enters the curved path from the lower paper path, it gradually flips towards the vertical direction. As the paper enters the upper paper path from the curved path, it gradually flips towards the horizontal direction. When the paper has completely entered the upper paper path, it is set horizontally, thus achieving a 180-degree flip of the paper.

[0025] A printer equipped with a paper feed path as described above.

[0026] A printer that uses the application method described above.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When paper exits the printer, it first enters the lower paper path. The blowing mechanism then feeds the paper from the lower paper path through a bend into the upper paper path, and finally blows it out of the upper paper path. During this process, the lower and upper paper paths are set parallel to each other. The paper enters the lower paper path horizontally, gradually flips vertically as it enters the bend, and gradually flips horizontally as it enters the upper paper path. Once the paper has fully entered the upper paper path, it is horizontal, thus achieving a 180-degree flip. Furthermore, the blowing mechanism accelerates the paper output speed, thereby achieving the goal of automatically flipping the paper 180 degrees and quickly exporting it.

[0029] 2. Furthermore, this application utilizes the fan controller and fan sensor to achieve intelligent control of the fan assembly, and utilizes the motor controller and motor sensor to achieve intelligent control of the motor and drive roller, thereby enabling the paper to pass through the lower and upper paper paths more quickly and smoothly, and this control method can also save energy.

[0030] 3. This application utilizes the fact that the two fan groups on the lower paper path have the same air pressure and the two fan groups on the upper paper path have the same air pressure. Therefore, the air force is in the middle of the lower and upper paper paths, and the lifting force of the air is balanced, so that the paper is in the middle of the lower and upper paper paths during the movement.

[0034] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0035] Example 1

[0036] Reference Figure 1 and Figure 2 This application discloses a paper feed path. In this embodiment, the paper feed path is applied to a printer. The paper feed path includes a lower paper feed path 1 and an upper paper feed path 2. In this embodiment, both the lower paper feed path 1 and the upper paper feed path 2 are horizontally arranged and connected by a bend 3. The lower paper feed path 1, the upper paper feed path 2, and the bend 3 are all connected and arranged in a continuous manner. The lower paper feed path 1 and the upper paper feed path 2 are arranged opposite to each other. It also includes a blowing mechanism 4, which is used to blow paper 12 from the lower paper feed path 1 through the bend 3 to the upper paper feed path 2 and then blow it out of the upper paper feed path 2.

[0037] The lower paper track 1 and the upper paper track 2 are set in parallel; by setting the lower paper track 1 and the upper paper track 2 in opposite directions, the paper 12 can be flipped; by setting the lower paper track 1 and the upper paper track 2 in parallel, the paper 12 can be flipped 180 degrees.

[0038] When paper 12 comes out of the printer, it first enters the lower paper path 1. The blowing mechanism 4 feeds paper 12 from the lower paper path 1 through the bend 3 into the upper paper path 2 and then blows paper 12 out from the upper paper path 2. During this process, the lower paper path 1 and the upper paper path 2 are set parallel to each other, so that paper 12 can be flipped 180 degrees. In addition, the blowing mechanism 4 blows paper 12 out of the paper path, which can speed up the paper 12 output speed, thereby achieving the purpose of automatically flipping paper 12 180 degrees and quickly outputting it from the paper path.

[0039] Reference Figure 1 and Figure 2 The blowing mechanism 4 includes a fan group 41. Two fan groups 41 are arranged opposite each other on the lower paper path 1 and the upper paper path 2. In this embodiment, each fan group 41 consists of 3 fan groups 41. The two fan groups 41 on the lower paper path 1 blow air towards the bend 3, and the two fan groups 41 on the upper paper path 2 blow air towards the side away from the bend 3. Several air holes 42 are opened near the blowing points of the fan groups 41 on both the lower paper path 1 and the upper paper path 2. The several air holes 42 are evenly arranged.

[0040] During operation, the fan assembly 41 blows air into the lower paper path 1 and the upper paper path 2 through the air holes 42. At this time, the air blowing direction of the two fan assemblies 41 on the lower paper path 1 is both towards the bend 3, which can blow the paper 12 from the lower paper path 1 to the bend 3. The air blowing direction of the two fan assemblies 41 on the upper paper path 2 is both towards the side away from the bend 3, which can blow the paper 12 in the bend 3 out of the upper paper path 2, thereby achieving the purpose of blowing the paper 12.

[0041] Reference Figure 1 The two fan groups 41 located on the lower paper path 1 have the same air pressure, and the two fan groups 41 located on the upper paper path 2 have the same air pressure. In this embodiment, the air pressure of the two fan groups 41 located on the lower paper path 1 and the two fan groups 41 located on the upper paper path 2 are the same. During the process of the fan group 41 blowing air into the air hole 42, since the fan groups 41 are arranged opposite each other with the same housing, the air force is in the middle of the lower paper path 1 and the upper paper path 2, and the lifting force of the gas is balanced, so that the paper 12 is located in the middle of the lower paper path 1 and the upper paper path 2 during the movement.

[0042] Reference Figure 1 and Figure 2 It also includes a fan controller 5, and a fan sensor 6 is provided at the entrance of the lower paper path 1. The fan controller 5, the fan sensor 6, and the fan assembly 41 are all electrically connected. In this embodiment, the fan controller 5 is connected to an external power supply 13. In this embodiment, the fan assembly 41, the fan controller 5, the fan sensor 6, and the power supply 13 are all electrically connected by wires. When the paper 12 comes out of the printer, the front end of the paper 12 first contacts the fan sensor 6. The fan sensor 6 sends a signal and transmits the signal to the fan controller 5. After receiving the signal, the fan controller 5 controls the fan assembly 41 to start working. The fan assembly 41 inflates the lower paper path 1 and the upper paper path 2 through the air hole 42, thereby achieving the purpose of the fan assembly 41 blowing the paper 12. This method does not require manual control and is intelligent and convenient.

[0043] Reference Figure 1 and Figure 2 A motor 7 is provided on the side of the upper paper path 2 near the bend 3. The motor 7 shaft is coaxially provided with an active roller 8. A driven roller 9 is also provided in the upper paper path 2 opposite to the active roller 8. The surfaces of the active roller 8 and the driven roller 9 are in contact.

[0044] It also includes a motor controller 10. A motor sensor 11 is provided on the side of the bend 3 near the upper paper path 2. The motor controller 10 is electrically connected to the motor 7 and the motor sensor 11. In this embodiment, the motor controller 10 is connected to an external power supply 13. In this embodiment, the motor 7, the motor controller 10, the motor sensor 11 and the power supply 13 are all electrically connected by wires.

[0045] When the paper 12 moves from the bend 3 to the upper paper path 2, when the front end of the paper 12 contacts the motor sensor 11, the motor sensor 11 sends a signal and transmits the signal to the motor controller 10. After receiving the signal, the motor controller 10 controls the motor 7 to start rotating. The motor 7 drives the active roller 8 to rotate, and the driven roller 9 is squeezed on the active roller 8 and driven to rotate. When the paper 12 enters, it will be sandwiched between the active roller 8 and the driven roller 9. The active roller 8 and the driven roller 9 carry the paper 12 into the upper paper path 2, so that the paper 12 can enter the upper paper path 2 more smoothly. Moreover, this method does not require manual control and is intelligent and convenient.

[0046] The implementation principle of Example 1 is as follows: Before operation, power supply 13 is turned on, and fan assembly 41, fan controller 5, fan sensor 6, motor 7, motor controller 10, and motor sensor 11 are all powered on. When paper 12 comes out of the printer, paper 12 enters the lower paper path 1 horizontally. At this time, the front end of paper 12 first contacts fan sensor 6. Fan sensor 6 will send a signal and transmit the signal to fan controller 5. After receiving the signal, fan controller 5 controls fan assembly 41 to start working and rotate to blow air. At this time, fan assembly 41 inflates the lower paper path 1 and upper paper path 2 through air hole 42.

[0047] The paper 12 is gradually blown into the bend 3 by the fan group 41 installed on it, which generates wind force towards the side of the bend 3. The paper 12 moves along the bend 3, gradually flips in the vertical direction, and moves along the bend 3 to the side of the upper paper path 2.

[0048] When the front end of the paper 12 passes the motor sensor 11 in the bend 3, the motor sensor 11 sends a signal and transmits the signal to the motor controller 10. After receiving the signal, the motor controller 10 controls the motor 7 to start rotating. The rotation of the motor 7 drives the active roller 8 to rotate. The driven roller 9 is pressed against the active roller 8 by gravity. The active roller 8 drives the driven roller 9 to rotate. The paper 12 is sandwiched between the active roller 8 and the driven roller 9. The active roller 8 and the driven roller 9 carry the paper 12 and gradually enter the upper paper path 2, thus smoothly pushing the paper 12 into the upper paper path 2.

[0049] After the paper 12 enters the upper paper path 2, it is gradually blown into the upper paper path 2 and out of the upper paper path 2 by the fan group 41 set thereon, which generates wind force towards the side away from the bend 3. That is, the paper 12 is discharged from the paper path. During the process of the paper 12 entering the upper paper path 2 from the bend 3, the paper 12 will gradually flip to the horizontal direction.

[0050] In this process, through the parallel and opposite lower paper path 1 and upper paper path 2, the paper 12 is blown from the lower paper path 1 into the upper paper path 2, which allows the paper 12 to be flipped 180 degrees. Furthermore, the blowing fan assembly 41 blows the paper 12 out of the paper path, which can also speed up the paper 12's output speed. Thus, the purpose of automatically flipping the paper 12 180 degrees and quickly outputting it through the paper path can be achieved. In addition, this application uses the fan controller 5 and the fan sensor 6 to achieve intelligent control of the fan assembly 41, and uses the motor controller 10 and the motor sensor 11 to achieve intelligent control of the motor 7 and the active roller 8. This makes the paper 12 pass through the lower paper path 1 and the upper paper path 2 more quickly and smoothly, and the whole process is intelligent.

[0051] Example 2

[0052] Reference Figure 1 and Figure 2 Based on the implementation of claim 1, an application method, employing the paper path described in embodiment 1 of this application, includes:

[0053] During operation, the paper 12 enters the lower paper path 1 and is blown towards the curved path 3 by the blowing mechanism 4. The paper 12 moves along the curved path 3. When the paper 12 enters between the active roller 8 and the driven roller 9, the active roller 8 and the driven roller 9 drive the paper 12 from the curved path 3 into the upper paper path 2. The paper 12 that has entered the upper paper path 2 is blown out of the upper paper path 2 by the blowing mechanism 4 and exits the paper path.

[0054] During operation, paper 12 enters the lower paper path 1. When fan sensor 6 detects paper 12, it transmits a signal to fan controller 5. Fan controller 5 controls fan assembly 41 to start working. Fan assembly 41 inflates the lower paper path 1 and upper paper path 2 through air holes 42. Paper 12 is blown from lower paper path 1 into curve 3. When motor sensor 11 detects paper 12, it transmits a signal to motor controller 10. Motor controller 10 controls motor 7 to start rotating. Motor 7 drives active roller 8 to rotate. Driven roller 9 is pressed against active roller 8 by gravity. Paper 12 is sandwiched between active roller 8 and driven roller 9. Active roller 8 and driven roller 9 carry paper 12 into upper paper path 2, thus completing the 180-degree flip of paper 12. After entering upper paper path 2, paper 12 is inflated by fan assembly 41 and blown out of upper paper path 2. Paper 12 is then discharged from the paper path.

[0055] During operation, paper 12 enters the lower paper path 1 horizontally. As paper 12 enters the curved path 3 from the lower paper path 1, it gradually flips to the vertical direction. As paper 12 enters the upper paper path 2 from the curved path 3, it gradually flips to the horizontal direction. When paper 12 has completely entered the upper paper path 2, paper 12 is set horizontally, thus achieving a 180-degree flip of paper 12.

[0056] This application, by setting the lower paper path 1 and the upper paper path 2 in parallel and opposite directions, can meet the requirement of automatically flipping the paper 12 by 180 degrees, which is particularly suitable for self-service printers. Furthermore, by setting up a fan group 41, a fan controller 5, a fan sensor 6, a motor 7, a motor controller 10, a motor sensor 11, an active roller 8, and a driven roller 9, this application can realize intelligent control of the opening and closing of the fan group 41 and the opening and closing of the motor 7 and the active roller 8, thereby enabling the paper 12 to be moved out of the paper path smoothly and quickly. Moreover, this control method can also save energy. This application can achieve the effect of automatically flipping the paper 12 by 180 degrees and quickly exporting it out of the paper path.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
