Description

Technical Field

[0002] In modern automated sheet media processing devices (such as cash deposit and withdrawal machines, bill processing machines, etc.), a reliable and efficient reversing device is required to effectively transport the media to different functional modules (such as the reception area, temporary storage area, and cash box, etc.). The reversing device solutions currently available on the market usually use electromagnets or motor drives, but these solutions all have their own limitations and disadvantages.

[0003] The commonly used solution in the prior art is to use a three-way electromagnet to directly drive the reversing blade shaft. The main disadvantages of this solution include complex internal structure, high requirements for parts precision and assembly precision, which makes it expensive and has a high manufacturing defect rate. Another method is to use a motor with a sensor to drive the reversing blade shaft. Although it is more flexible in reversing control, the frequent start and stop and direction switching of the motor will lead to problems such as loss of step, overshoot, low holding force and inaccurate positioning. It will also bring about greater power consumption and poor use effect.

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. 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.

[0036] See also Figures 1 to 5 As shown, an embodiment of the present invention provides a reversing device 10, which includes a fixed structure 100, an output shaft 200, a first reversing component 300 and a second reversing component 400; the output shaft 200 is rotatably connected to the fixed structure 100; the first reversing component 300 and the fixed structure 100 are relatively movable, and the output end of the first reversing component 300 is connected to the output shaft 200 and is used to drive the output shaft 200 to rotate relative to the fixed structure 100; the second reversing component 400 is connected to the fixed structure 100, and the second reversing component 400 is transmission-connected to the first reversing component 300 and is used to drive the first reversing component 300 to rotate relative to the fixed structure 100.

[0037] In the reversing device 10 of the present embodiment, by setting the first reversing component 300 and the second reversing component 400, the first reversing component 300 can drive the output shaft 200 to rotate relative to the fixed structure 100 within a first range, and the second reversing component 400 can drive the first reversing component 300 to rotate relative to the fixed structure 100 within a second range. By superimposing the first range and the second range, the adjustment range of the output shaft 200 can be effectively increased. Compared with the solution of using a three-way electromagnet, the manufacturing cost can be effectively reduced, and the structure is simple and the reliability is improved. Compared with the solution of using a motor and a sensor, the power element can drive the output shaft 200 to switch direction without frequent starting and stopping, which can not only reduce the manufacturing cost but also improve the overall reliability of the reversing device 10.

[0038] In the reversing device 10 of this embodiment, by setting the first reversing component 300 and the second reversing component 400 in cooperation, a wide range of rotation range adjustment of the output shaft 200 can be achieved, which not only has a simple structure and low manufacturing cost, but also has improved reliability and good use effect.

[0039] Specifically, the second reversing component 400 includes a second driving member 410 and a driving tooth plate 420, the second driving member 410 is connected to the fixed structure 100, the driving tooth plate 420 is connected to the output end of the second driving member 410, and the driving tooth plate 420 is meshedly connected with the first reversing component 300 to drive the first reversing component 300 to rotate relative to the fixed structure 100.

[0040] In this configuration, since the second driving member 410 is fixedly connected to the fixed structure 100, the driving tooth plate 420 can be driven to rotate relative to the fixed structure 100 by starting the second driving member 410. At this time, the first reversing assembly 300 can be driven to rotate relative to the fixed structure 100 by the meshing connection between the driving tooth plate 420 and the first reversing assembly 300. In one embodiment, the second driving member 410 can be a servo motor so that the second reversing assembly 400 has a higher adjustment accuracy; in a preferred embodiment, the second driving member 410 can be a bidirectional electromagnet. In this case, the second driving member 410 only has a driving function in two directions. However, the use of a bidirectional electromagnet can make the second reversing assembly 400 have a lower manufacturing cost. At the same time, due to the simple driving form, the operating reliability and adjustment rate of the second reversing assembly 400 can also be improved.

[0041] In one embodiment, a sector-shaped tooth portion is provided on a side of the driving tooth plate 420 away from the output end of the second driving member 410, and the tooth portion is meshedly connected with the first reversing receiving member.

[0042] In this embodiment, the teeth of the driving tooth plate 420 can be within the first angle range of 3 in the circumferential direction of the driving tooth plate 420. At this time, the rotation angle of the second driving member 410 is also the same as the first angle range, thereby limiting the driving range of the second driving member 410, that is, the transmission range of the driving tooth plate 420 and the first reversing assembly 300; Figure 3 As shown, the first reversing assembly 300 can be driven to rotate angles a and b relative to the fixed structure 100 by rotating the second driving member 410, thereby controlling the reversing blade 30 to rotate between angles a and b to achieve the two-position adjustment function.

[0043] Specifically, the first reversing assembly 300 includes a first driving member 310 and a connecting frame 320, the output end of the first driving member 310 is connected to the output shaft 200, the connecting frame 320 is connected to the first driving member 310, and the driving gear plate 420 is meshedly connected to the connecting frame 320 and is used to drive the connecting frame 320 to rotate relative to the fixed structure 100 to drive the output shaft 200 to rotate.

[0044] In this embodiment, by setting the first driving member 310 to be connected with the connecting frame 320, when the second reversing assembly 400 is started to drive the first reversing assembly 300 to rotate, the connecting frame 320 can drive the first driving member 310 to rotate relative to the fixed structure 100, and when the first driving member 310 is not started, the reversing blade 30 can be driven to adjust at the angle a and the angle b; Figure 4 As shown, when the first driving member 310 drives the output shaft 200 to further rotate relative to the fixed structure 100, it can cooperate with the rotation range of the second driving member 410 to drive the reversing blade 30 to have an additional adjustment range of angle c and angle d. Thus, by setting the first reversing component 300 and the second reversing component 400 to cooperate, the direction of the reversing blade 30 can be adjusted between angle a, angle b, angle c and angle d. Specifically, the first driving member 310 can be a servo motor so that the second reversing component 400 has a higher adjustment accuracy; in a preferred embodiment, the first driving member 310 can be a bidirectional electromagnet. At this time, the first driving member 310 only has the driving function of two directions, but the use of a bidirectional electromagnet can make the first reversing component 300 have a lower manufacturing cost, and at the same time, due to the simple driving form, the operation reliability and adjustment rate of the first reversing component 300 can also be improved.

[0045] Furthermore, the first reversing assembly 300 also includes a counterweight block 330, which is detachably connected to the connecting frame 320. The first driving member 310 is a bidirectional electromagnet, and the counterweight block 330 is located on the side of the axis of the output shaft 200 away from the center of gravity of the first driving member 310. The counterweight block 330 is used to offset the gravitational torque of the first driving member 310.

[0046] Thus, by setting a counterweight block 330 that cooperates with the first driving member 310 on the connecting frame 320, when the first driving member 310 drives the output shaft 200 to rotate, the counterweight block 330 can balance the gravity torque of the first driving member 310 to improve the overall stability of the reversing device 10 when the first reversing assembly 300 is running.

[0047] In one implementation, there are multiple counterweight blocks 330 , and the multiple counterweight blocks 330 are arranged at intervals along the circumferential direction of the output shaft 200 .

[0048] In this embodiment, by setting a plurality of counterweight blocks 330 to cooperate with the first driving member 310, the gravity torque of the first driving member 310 can be further balanced, thereby further improving the operating stability of the first reversing assembly 300; specifically, the plurality of counterweight blocks 330 are arranged at intervals along the circumferential direction of the rotation center axis of the connecting frame 320.

[0049] Specifically, the first driving member 310 is detachably connected to the output shaft 200 .

[0050] When assembling the reversing device 10 of this embodiment, first connect the output shaft 200 to the fixed structure 100, and make the output shaft 200 able to rotate stably equivalent to the fixed structure 100, and then connect and fix the output end of the first drive member 310 to the output shaft 200, and the assembly of the output shaft 200 and the first reversing assembly 300 can be completed. Specifically, the first drive member 310 and the output shaft 200 can be combined in a detachable connection manner such as threaded connection, clamping, magnetic connection, etc.

[0051] In one embodiment, a connecting hole 210 is opened at one end of the output shaft 200 facing the first reversing assembly 300, the output end of the first driving member 310 is inserted into the connecting hole 210 and connected to the output shaft 200, and the output shaft 200 is rotatably connected to the fixed structure 100 through a bearing 220.

[0052] When assembling the reversing device 10 of this embodiment, first connect the output shaft 200 to the fixed structure 100, and enable the output shaft 200 to rotate stably equivalent to the fixed structure 100, and then insert the output end of the first drive member 310 into the connecting hole 210 of the output shaft 200 to connect and fix the first reversing assembly 300 and the output shaft 200. In some embodiments, it can also be connected to the output shaft 200 by a fastening screw, and the output shaft of the first drive member 310 is fixedly connected to the output shaft 200.

[0053] The present invention also provides a medium conveying device 1, which includes a frame 20, a reversing blade 30 and a reversing device 10 in any one of the above embodiments: the frame 20 is provided with a conveying device (not shown in the figure) for conveying the medium; the reversing blade 30 is rotatably connected to the frame 20 and is used to change the conveying direction of the medium; the fixed structure 100 of the reversing device 10 is connected to the frame 20, and one end of the output shaft 200 is rotatably connected to the frame 20, and the other end of the output shaft 200 is connected to the reversing blade 30. Specifically, the conveying device can be a conveying device of the type of belt transmission, push transmission, etc.

[0054] It can be understood that, in the medium conveying device 1 of the present embodiment, by setting the reversing device 10 in any one of the above embodiments, the reversing device 10 is provided with a first reversing component 300 and a second reversing component 400, and the first reversing component 300 can drive the output shaft 200 to rotate relative to the fixed structure 100 within a first range, and the second reversing component 400 can drive the first reversing component 300 to rotate relative to the fixed structure 100 within a second range. By superimposing the first range and the second range, the adjustment range of the output shaft 200 can be effectively increased. Compared with the solution of using a three-way electromagnet, the manufacturing cost can be effectively reduced, and the structure is simple and the reliability is improved. Compared with the solution of using a motor and a sensor, the power element does not need to be frequently started and stopped to realize the driving output shaft 200 to switch direction, which can not only reduce the manufacturing cost, but also improve the overall reliability of the reversing device 10.

[0055] Specifically, one end of the reversing blade 30 is rotatably connected to the frame 20 , and the output shaft 200 is inserted into the other end of the reversing blade 30 and rotatably connected to the frame 20 .

[0056] In this embodiment, one end of the reversing blade 30 can be rotatably connected to the frame 20 through a bearing, and the other end of the output shaft 200 is connected to the bearing 220, so that the output shaft 200 is combined with the fixed structure 100 through two-point support and realizes the rotation function of the output shaft 200.

The structure is simple and easy to assemble.
