The sorting platform is often set to be electrically driven, which includes a motor, two rollers and a belt for linking the two rollers. The motor drives one roller to run. Due to the high cost of the electric drive roller, it is difficult to obtain a large torque under the premise of small size. Therefore, there are great limitations in the sorting device. Utility Model Content

[0005] (II) Technical solution

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0008] (III) Beneficial effects

[0009] The beneficial effect of the utility model is that the second rotating shaft is the input shaft of the power source, the driving wheel drives the second rotating shaft to rotate, and cooperates with the first coupling disc and the second coupling disc, so that the first coupling disc and the second coupling disc can be switched between the separation state and the combination state in a predetermined period of time, thereby realizing the sorting control of the sorting device. Since the first coupling disc and the second coupling disc can rely on each other's magnetic adsorption to transmit torque when switching to the combination state, and can quickly and completely disengage from the linkage when switching to the separation state; therefore, the mutual viscosity between the states of the first coupling disc and the second coupling disc will be reduced, thereby improving the response time when the states of the first coupling disc and the second coupling disc are switched, and improving the sorting accuracy of the sorting device.

[0022] In order to better explain the present invention and facilitate understanding, the following Figure 1-3, the utility model is described in detail through specific implementation methods. Among them, the directional nouns such as "upper" and "lower" mentioned in this article are Figure 1 The orientation is used as a reference.

[0023] Embodiment 1:

[0024] Reference Figure 1-Figure 3 , an embodiment of the utility model provides a sorting unit, the sorting unit includes a frame 1 and a driving assembly 2 connected to the frame 1; the driving assembly 2 includes a first rotating shaft 21 directly or indirectly connected to the frame 1 for rotation, and a power source 22 located on one side of the first rotating shaft 21; the power source 22 includes a second rotating shaft 221, a first coupling disk 222 and a second coupling disk 223 respectively connected to the first rotating shaft 21 and the second rotating shaft 221 at one end close to each other, and a driving wheel 224 connected to the second rotating shaft 221, the driving wheel 224 can be passively rotated when the sorting unit moves, thereby driving the second rotating shaft 221 to operate; the first coupling disk 222 and the second coupling disk 223 can switch between a coupled state and a separated state, so that torque can be transmitted or torque transmission can be disconnected between the first rotating shaft 21 and the second rotating shaft 221; wherein the first coupling disk 222 and the second coupling disk 223 are both magnetic parts that can be attracted to each other when close to each other.

[0025] In this embodiment, the second rotating shaft 221 is the input shaft of the power source 22, and the driving wheel 224 drives the second rotating shaft 221 to rotate, and cooperates with the first coupling disc 222 and the second coupling disc 223, so that the first coupling disc 222 and the second coupling disc 223 can be switched between the separation state and the combination state in a predetermined period of time, thereby realizing the sorting control of the sorting device. Since the first coupling disc 222 and the second coupling disc 223 can rely on each other's magnetic adsorption to transmit torque when switching to the combination state, and can quickly and completely disengage from the linkage when switching to the separation state; therefore, the mutual viscosity between the states of the first coupling disc 222 and the second coupling disc 223 will be reduced, thereby improving the response time when the states of the first coupling disc 222 and the second coupling disc 223 are switched, and improving the sorting accuracy of the sorting device.

[0026] Moreover, the adoption of this torque transmission method reduces the purchase cost of the traditional electric roller, and also enables the torque transmission between the first rotating shaft 21 and the second rotating shaft 221 to have a good overload protection function. By adjusting the mutual adsorption force between the magnetic member and the first coupling disk 222 and the second coupling disk 223 when they are in a combined state, the torque threshold when overload protection occurs can be changed, thereby improving the flexibility of use of the sorting device.

[0027] Specifically, the combined state and the separated state in this embodiment refer to the fact that the first coupling disk 222 and the second coupling disk 223 can transmit torque or cannot transmit torque, and are not structurally combined or separated. Even if a certain distance is maintained between the first coupling disk 222 and the second coupling disk 223, if torque can be transmitted between the two, it is also within the range of the combined state.

[0028] The sorting unit further comprises a sorting platform 4 rotatably connected to the frame 1 , and the second rotating shaft 221 is drivingly connected to the torque input end of the sorting platform 4 .

[0029] The sorting platforms 4 are arranged in multiple groups, and the driving assemblies 2 are arranged in multiple groups corresponding to the sorting platforms 4 one by one; the power sources 22 are arranged in two groups located on both sides of the first rotating shaft 21, and the corresponding second rotating shafts 221 are drivingly connected to the torque input ends of the corresponding sorting platforms 4 to respectively control the forward or reverse rotation of the corresponding sorting platforms 4.

[0030] In this embodiment, the sorting platform 4 is also used as the actuator of the sorting unit. The sorting platform 4 is used to perform express sorting operations, and its running direction is along the horizontal vertical direction when the sorting unit moves. The sorting platform 4 can be set to multiple groups, and the corresponding drive assembly 2 that drives the sorting platform 4 to run is also set to multiple groups, thereby improving the overall sorting efficiency of the sorting unit.

[0031] Even compared with the traditional friction electromagnetic clutch, in this patent, since the first coupling disk 222 and the second coupling disk 223 always maintain a predetermined distance, when the two are switched to the separation state, the torque transmission can be quickly and non-sticky disconnected, thereby improving the control accuracy of the sorting platform 4.

[0032] At the same time, a driving assembly 2 includes two power sources 22, and the two power sources 22 are located on both sides of the first rotating shaft 21. Through the flexible arrangement of the transmission mechanism, a driving assembly 2 can drive the sorting platform 4 to rotate forward or reverse, thereby improving the sorting flexibility of the sorting unit.

[0033] A sorting platform 4 has two torque input ends, and both are drivingly connected to the corresponding second rotating shaft 221 through a transmission mechanism. By adjusting the torque transmission direction of the transmission mechanism, the torque direction received by the sorting platform 4 can be changed, thereby enabling the sorting platform 4 to rotate forward and reverse.

[0034] The specific transmission mechanism may be a chain sprocket transmission mechanism and a bevel gear transmission mechanism, and the bevel gear transmission mechanism is used to adjust the torque transmission direction.

[0035] The sorting unit further comprises casters, which are vertically hinged to the frame 1 and can support the frame 1 .

[0036] The sorting unit can be supported not only by the driving wheel 224, but also by casters. The two can be arranged to play a supporting role at the same time. It can also be arranged that in the sorting section of the sorting unit, the sorting unit is supported by the driving wheel 224, and in the non-sorting section of the sorting unit, the sorting unit is supported by the casters.

[0037] In the present embodiment, the casters are arranged to be vertically rotatable in order to make the casters match the turning conditions of the sorting unit. In most cases, when the sorting unit has a sorting demand, the sorting unit runs in a straight line. Therefore, when the sorting unit has an operation demand, the sorting unit is supported by the first driving wheel 224, and when the sorting unit has no operation demand, the sorting unit is supported by the casters. This can reduce the wear of the driving wheel 224 and increase the service life of the driving wheel 224.

[0038] Specifically, the driving wheel 224 and the casters are both configured as rubber-coated wheels.

[0039] More specifically, the driving wheel 224 can be configured as a polylactone rubber-coated wheel, and the caster wheel can be configured as a polyurethane rubber-coated wheel.

[0040] Embodiment 2:

[0041] Reference Figure 1-Figure 3 In addition to all the technical solutions of the above embodiments, the embodiments of the present utility model further have the following technical solutions:

[0042] The first coupling disk 222 and the second coupling disk 223 are both fixedly connected to the corresponding first rotating shaft 21 and the second rotating shaft 221, and one of the second coupling disk 223 and the second coupling disk 223 is an electromagnet and the other is a permanent magnet; the first disk body and the second disk body maintain a predetermined distance.

[0043] In this embodiment, the first coupling disk 222 and the second coupling disk 223 can be fixed to the ends of the first rotating shaft 21 and the second rotating shaft 221 by bolt connection, and the distance between the first coupling disk 222 and the second coupling disk 223 remains unchanged. At this distance, the torque can be reliably transmitted between the first coupling disk 222 and the second coupling disk 223.

[0044] When torque needs to be transmitted, one of the electromagnets in the first coupling disk 222 and the second coupling disk 223 is energized to generate magnetic force. The magnetic force between the first coupling disk 222 and the second coupling disk 223 can transmit torque between the two, and can also play an overload protection role when the sorting platform 4 is overloaded.

[0045] Since the two are always kept in a completely separated state, when the two are switched from the coupled state to the separated state, the torque transmission between the two can be cut off by the clutch, thereby further improving the control response speed of the sorting unit.

[0046] Specifically, the second coupling disk 223 may be configured as an electromagnet, and the first coupling disk 222 may be configured as a permanent magnet.

[0047] More specifically, by changing the current flowing through the electromagnet, the magnitude of the magnetic force between the first coupling disk 222 and the second coupling disk 223 can be changed, thereby adjusting the overload protection threshold.

[0048] Embodiment 3:

[0049] Reference Figure 1-Figure 3 In addition to all the technical solutions of the above-mentioned embodiment 1, the embodiment of the utility model further has the following technical solutions:

[0050] The first coupling disk 222 is fixedly connected to the first rotating shaft 21, and the second coupling disk 223 is slidably connected to the second rotating shaft 221 along the axial direction of the second rotating shaft 221; the sorting device also includes a driving mechanism 3 to drive the second coupling disk 223 to approach or move away from the first coupling disk 222, so that the first coupling disk 222 and the second coupling disk 223 can switch between a combined state and a separated state.

[0051] In this embodiment, the first coupling disk 222 and the second coupling disk 223 do not rely on setting at least one of them as an electromagnet to control the mutual adsorption of the two, but change the magnetic force between the two by changing the distance between the two. In this way, it is possible to realize the state switching of the two and adjust the threshold of the transmission torque of the overload protection condition of the two. While ensuring the state switching response speed, the control flexibility of the sorting platform 4 is improved.

[0052] The second coupling disk 223 is driven to slide by the driving mechanism 3 , so that the second coupling disk 223 is close to or away from the first coupling disk 222 .

[0053] Embodiment 4:

[0054] Reference Figure 1-Figure 3 In addition to all the technical solutions of the above embodiments, embodiment 3 of the present utility model further has the following technical solutions:

[0055] The driving mechanism 3 includes a telescopic driving member connected to the frame 1 , and a driving end of the telescopic driving member is drivingly connected to the second coupling disk 223 to drive the second coupling disk 223 to approach or move away from the first coupling disk 222 .

[0056] In this embodiment, the driving mechanism 3 is a telescopic driving member, such as an electric telescopic rod, which drives the second coupling disk 223 to slide through the high-precision electric telescopic rod, thereby ensuring the control accuracy of the sorting platform 4.

[0057] Embodiment 5:

[0058] Reference Figure 1-Figure 3 In addition to all the technical solutions of the above-mentioned embodiment 3, the embodiment of the utility model further has the following technical solutions:

[0059] The driving mechanism 3 includes a track 32, and the track 32 includes a connecting section 321 and a separating section 322 which are continuous with each other. The second coupling disk 223 can cooperate with the track 32 directly or indirectly; when the second coupling disk 223 cooperates with the connecting section 321, the first coupling disk 222 and the second coupling disk 223 remain in a connected state; when the second coupling disk 223 cooperates with the separating section 322, the first coupling disk 222 and the second coupling disk 223 remain in a separated state; the track 32 also includes a transition section 323 connecting the connecting section 321 and the separating section 322 to realize the position transition of the second coupling disk 223 between the connecting section 321 and the separating section 322; the connecting section 321 and the separating section 322 both extend along the running direction of the sorting unit, and the transition section 323 extends obliquely relative to the running direction of the sorting unit.

[0060] In this embodiment, the driving mechanism 3 includes a track 32. The position of the second coupling disk 223 on the second rotating shaft 221 is changed by the cooperation between the track 32 and the second coupling disk 223, so that the first coupling disk 222 and the second coupling disk 223 can be switched between a coupled state and a separated state; by adjusting the ends of the two when they are in the coupled state, the threshold of the transmission torque of the overload protection condition can be changed, thereby ensuring the state switching response speed and improving the control flexibility of the sorting platform 4.

[0061] The distance between the first coupling disk 222 and the second coupling disk 223 when the second coupling disk 223 cooperates with the separation section 322 is greater than the distance between the first coupling disk 222 and the second coupling disk 223 when the second coupling disk 223 cooperates with the combination section 321 .

[0062] When the second coupling disk 223 cooperates with the transition section 323, the second coupling disk 223 switches from the state of cooperating with the separation section 322 to the state of cooperating with the combining section 321; or the second coupling disk 223 switches from the state of cooperating with the combining section 321 to the state of cooperating with the separation section 322. The whole process lasts for a very short time and basically does not affect the control response speed of the sorting platform 4.

[0063] The driving mechanism 3 further includes a toggle member 31 connected to the second coupling disc 223, and the toggle member 31 matches the track 32 to drive the second coupling disc 223 to approach or move away from the first coupling disc 222;

[0064] The driving mechanism 3 further comprises a mounting frame, in which the toggle piece 31 is slidably connected along the axial direction of the first rotating shaft 21 to improve the stability of the toggle piece when sliding.

[0065] Specifically, the toggle member 31 can be set as a fork structure and in a sheet shape, with its two ends extending along the running direction of the sorting unit. After the middle part is twisted, it extends in a direction perpendicular to the running direction of the sorting unit, and the middle part is slidably connected to the mounting frame to improve the integrity of the toggle member 31 and reduce its cost.

[0066] Specifically, a groove is formed in the track 32 , and the second coupling plate 223 cooperates with the groove directly or indirectly, such as by cooperating with the groove through the toggle member 31 , so as to ensure the stability of the second coupling plate 223 .

[0067] The driving mechanism 3 also includes an elastic member, which provides an elastic force for the second coupling disk 223 to approach or move away from the first coupling disk 222; the elastic member is a spring, and the two ends of the spring are respectively abutted against the second coupling disk 223 and the frame 1, and provide a force for the second coupling disk 223 to approach the first coupling disk 222.

[0068] In this embodiment, the elastic member is used to assist the second coupling disk 223 in resetting on the second rotating shaft 221. At the same time, the existence of the elastic force can also improve the tightness of the fit between the second coupling disk 223 and the track 32, thereby improving the stability of the second coupling disk 223 and the control accuracy of the sorting platform 4.

[0069] Embodiment 6:

[0070] Reference Figure 1-Figure 3 In addition to providing a sorting and transporting line, the embodiments of the present invention include the sorting device in any of the above technical solutions, and the sorting units corresponding to the multiple sorting devices are connected end to end and run along the line.

[0071] When the track 32 is used as the driving mechanism 3 , the track 32 is directly fixed on the line body of the sorting and transporting line. When the sorting unit runs along the line body, the toggle member 31 of the second coupling disk 223 cooperates with the groove of the track 32 .
