[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1

[0026] The embodiment of the present invention specifically describes a paper medium reversing device: 1. Connection relationship: This embodiment provides a paper medium reversing device, such as Figure 1 , 2 , 3, 4, 5, 6, 7, fixed on the base bracket 11, the paper medium reversing device includes: a coaxially connected reversing support 3, a reversing swing rod 4 and a structure to be reversing 9, and also includes a second tension spring 6 connected to the free end of the reversing swing rod 4 and the reversing support 3, and also includes a first tension spring 5 connected to the base bracket 11 and the reversing support 3; The reversing rocker rod 4 is fixedly connected to the structure to be reversing 9; The reversing support 3 is provided with a first limiting member 201, a second limiting member 202, a fifth limiting member 205 and a sixth limiting member 206; The reversing rocker 4 is used to cooperate with the second tension spring 6 to rotate between the first limiter 201 and the second limiter 202, and drive the reversing support 3 to rotate through the first limiter 201 or the second limiter 202, and limit the rotation direction of the reversing support 3; The fifth limiting member 205 and the sixth limiting member 206 are used to cooperate with the adjusting limiting member 17 to limit the rotation direction of the reversing support 3, and then limit the rotation direction of the reversing rocker 4, so as to ultimately limit the rotation direction of the structure to be commutated 9.

[0027] Specifically, the tension of the first tension spring 5 is greater than the tension of the second tension spring 6 .

[0028] The paper medium reversing device further comprises a reversing shaft 8 , on which a reversing support 3 passes through, and a reversing rocker rod 4 and a structure to be reversed 9 are fixedly passed through.

[0029] The reversing support 3 penetrates the reversing shaft 8 based on a circular hole (which may be the support through hole 208 ); the reversing rocker arm 4 is fixed on the reversing shaft 8 based on an asymmetric hole (which may be a D-shaped rocker arm through hole 302 ).

[0030] Specifically, the purpose of using an asymmetric hole in the reversing rocker 4 is to prevent relative movement between the reversing rocker 4, the reversing shaft 8, and the structure to be reversing 9. This purpose can also be achieved by using pin holes, screws, etc.

[0031] The reversing shaft 8 is also fixedly provided with an induction sheet 12; The base support 11 is provided with a plurality of sensors for sensing the position of the sensing sheet 12 to determine the rotation direction of the structure to be commutated 9 .

[0032] Specifically, a horizontal position sensor and a vertical position sensor may be provided, and different sensors may be provided according to angle requirements.

[0033] The paper medium reversing device also includes: a motor 15 and a driving wheel 16, a follower wheel 1 and an execution wheel 2 which are meshed in sequence; The motor 15 is fixed on the base bracket 11 and is fixedly connected to the driving wheel 16; The actuator wheel 2 is fixedly mounted on and passes through the reversing shaft 8 .

[0034] The regulating limiter 17 is also used to adjust the initial rotation direction of the structure to be reversed 9 .

[0035] The base bracket 11 is also fixedly provided with a first shaft 7 for connecting the first tension spring 5. The first shaft can be fixedly provided at the center of the follower wheel 1.

[0036] The reversing support 3 is provided with a third connection position 203 and a fourth connection position 204, and the free end of the reversing swing rod 4 is provided with a swing rod connection position 301, both of which are used to connect the tension spring. Specifically, one end of the first tension spring 5 is connected to the first shaft 7, and the other end is connected to the fourth connection position 204; one end of the second tension spring 6 is connected to the swing rod connection position 301, and the other end is connected to the third connection position 203.

[0037] Specifically, the reversing shaft 8 is penetrated in sequence by: the structure to be reversed 9, the base bracket 11, the executive wheel 2, the reversing support 3, the induction plate 12 and the reversing rocker 4; among them, the structure to be reversed 9, the executive wheel 2, the induction plate 12 and the reversing rocker 4 are fixed on the reversing shaft 8, and the five are always relatively stationary.

[0038] Adjustment of the initial state of the equipment: Before the module works, it is necessary to confirm whether the initial angle of the structure to be commutated 9 is the current required state. If the angle is incorrect due to problems with parts processing accuracy and assembly process, the commutation position adjustment member 17 is required to adjust the installation position of the structure to be commutated 9.

[0039] The seventh protrusion 207 is reserved for commutator components at different positions.

[0040] (II) The specific commutation process is as follows: Process 1: The first state (can be Figure 5 The preparation state) to the third state (which can be Figure 7 Deposit status) process: After receiving the deposit instruction, a clockwise rotation instruction is issued to the motor 15, thereby driving the driving wheel 16 fixed on the motor 15 to rotate clockwise, and driving the follower wheel 1 to rotate counterclockwise through the engagement of the teeth, and then driving the executing wheel 2 to rotate clockwise through the engagement of the teeth. Because the executing wheel 2, the structure to be reversed 9 (the structure to be reversed 9 can be a reversing tooth or other structure), the induction plate 12, and the reversing rocker 4 are all fixed on the reversing shaft 8, the above structures will all rotate clockwise.

[0041] Since one end of the second tension spring 6 is connected to one end of the reversing rocker 4, the second tension spring 6 is stressed. In this process, the first limiter 201 and the second limiter 202 directly limit the swing range of the free end of the reversing rocker 4, thereby indirectly controlling the swing range of the structure to be reversed 9. Specifically, the reversing rocker 4 collides with the second limiter 202, thereby driving the reversing support 3 to be kept in a stationary state under the tensile force of the first tension spring 5, thereby making the structure to be reversed 9 stay at Figure 7 In this process, the fifth limiting member 205 always collides with the adjusting limiting member 17, thereby limiting the reversing support 3.

[0042] At this time, the motor 15 stops rotating, and the reversing swing rod 4 stays at Figure 7 Therefore, the structure to be switched 9 stays at Figure 7 Angle shown.

[0043] In this process, if there is no first tension spring 5 and second tension spring 6, it will be difficult for the sensor sheet 12 to be stably in the Figure 7 In the deposit state shown, the whole device can be made more stable by the continuous tensile force of the first tension spring 5 and the second tension spring 6. At this time, the sensing sheet 12 is separated from the sensing area of ​​the first sensor 13 (which can be a horizontal position sensor), and then the first sensor 13 sends a signal, and the paper medium can be reversed and transported to the corresponding position through the to-be-reversed structure 9.

[0044] Process 2: The third state (can be Figure 7 The deposit status) returns to the first status (which can be Figure 5 Preparation state) process: After the detection process is completed, the motor 15 is rotated counterclockwise, the driving wheel 16 rotates counterclockwise, the driven wheel 1 rotates clockwise, and the execution wheel 2 rotates counterclockwise. The execution wheel 2 is fixed on the reversing swing rod 4, so the reversing swing rod 4 rotates counterclockwise. Through the limiting effect of the first limiting member 201, and the torque provided by the second tension spring 6 is smaller than the torque provided by the first tension spring 5, when the motor 15 stops rotating, the final stability is reached. Figure 5 Shown in ready state.

[0045] Process 3: The first state (can be Figure 5 ready state) to the second state (which can be Figure 6 Withdrawal status After receiving the withdrawal instruction, the motor 15 is rotated counterclockwise, thereby driving the driving wheel 16 fixed on the motor 15 to rotate counterclockwise, and the follower wheel 1 is driven to rotate clockwise through the tooth engagement, and then the execution wheel 2 is driven to rotate counterclockwise through the tooth engagement. Therefore, the reversing structure 9, the induction plate 12, the reversing rocker arm 4, and the reversing shaft 8 all rotate counterclockwise; during the process, the reversing rocker arm 4 collides with the first limit member 201, so that the first tension spring 5 will be subjected to force.

[0046] Continue to rotate the motor 15 counterclockwise, the power of the motor 15 will overcome the tension provided by the first tension spring 5, so that the reversing support 3 rotates counterclockwise, until the sixth limiter 206 on the reversing support 3 collides with the adjustment limiter 17, generating a limit effect, at this time the motor 15 stops rotating, the first tension spring 5 stretches to provide tension, so that the structure stays at Figure 6 Withdrawal status shown.

[0047] At this time, the sensing sheet 12 is separated from the sensing area of ​​the first sensor 13 , and after the second sensor 14 detects the sensing sheet 12 , the paper medium can be transported to the corresponding position.

[0048] Process 4: Second state (can be Figure 6 The withdrawal status) is classified into the first state (which can be Figure 5 Readiness status) After detecting that process three is finished, the motor 15 is rotated clockwise, the driving wheel 16 rotates clockwise, the driven wheel 1 rotates counterclockwise, and the executing wheel 2 rotates clockwise. Since the executing wheel 2 rotates clockwise, the structure to be commutated 9, the induction sheet 12, and the commutation swing rod 4 fixedly connected thereto all rotate clockwise.

[0049] The second tension spring 6 with the smallest tension force is first subjected to force and rotates clockwise with the reversing swing rod 4, so that the reversing swing rod 4 first collides with the second stopper 202. Then, the reversing swing rod 4 gives a clockwise thrust to the reversing support 3, and the motor 15 continues to operate, so that the reversing support 3 overcomes the first tension spring 5 with a larger tension force and rotates together, that is, the reversing support 3 continues to rotate clockwise.

[0050] When the fifth stopper 205 of the reversing support 3 finally collides with the adjustment stopper 17, the motor 15 stops rotating. Figure 5 ) is the intermediate state of transition, the reversing support 3 rotates too much, causing the reversing rocker 4 and the induction plate 12 to turn to the deposit state ( Figure 7 ).

[0051] In order to correct the over-rotation of the reversing support 3, it is finally necessary to make the motor 15 rotate counterclockwise and execute the process of process 2. For details, see process 2, which will not be repeated here.

[0052] The beneficial effects of the embodiments of the present invention are as follows: A. The present application solves the problem that the commutation angle of the commutator is a fixed value. For commutation angles with different requirements, only a specific commutator support needs to be designed, which greatly facilitates the design work of different commutation angles at different positions during the operation of paper media during the design process of the movement.

[0053] B. The present application replaces the use of a tension lock as the driving force of the structure to be reversed by adding a root tension spring to achieve functional substitution. The tension spring can ensure that the tension value is constant under a certain deformation amount, making the assembly production process more convenient.

[0054] C. The present application realizes the function of the structure to be reversed to three directions at the same position, and only uses a DC motor plus a gear set (i.e., a driving gear, a follower gear, and an execution gear), a withdrawal spring, and a deposit spring to realize the function of reversing in three directions. The design is simple and the function is stable.

[0055] D. The parts used in the present invention are easy to design and the design process is accelerated; the materials are common and the processing is simple, thereby greatly reducing the movement cost in the procurement link.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
