[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] With the continuous development of the logistics industry, the application of accumulation rollers is becoming more and more common. However, the current transmission method of accumulation rollers is to add a sprocket to one end of the roller. The sprocket drives the roller to rotate through friction plates. When the roller needs to store items, it needs to stop rotating. At this time, the sprocket friction plates are disengaged from the roller. Since the power source drives the sprocket device, the power source needs to be fixed on the frame, which makes the overall frame structure complicated.

[0019] There is an urgent need for a compact, powerful electric drive device that can directly or indirectly drive materials and goods. However, most existing electric rollers use a direct drive method via a motor and reducer, which is not convenient for realizing the accumulation function of the roller.

[0020] Based on this, embodiments of the present invention provide an accumulating electric roller that organically combines a modular motor with an accumulating module mechanism and a high-efficiency planetary reduction mechanism, achieving an integrated design of the drive system and the roller body. Inside the roller, the roller is directly driven by the accumulating module and the planetary reduction output disc. By controlling the action of the accumulating module, the transmission or interruption of motor power to the roller body can be precisely adjusted, thereby completing the accumulating function and achieving precise accumulating of objects on the conveyor line.

[0021] like Figures 1 to 5As shown in the figure, the present invention provides an accumulating electric roller, including a roller body 1, a motor 4, an accumulating module and a reduction module 7.

[0022] Both ends of the cylinder 1 are sealed with fixed end caps 2. One of the fixed end caps 2 is equipped with a linkage shaft 22, which is coaxial with the cylinder 1 and is used to support the cylinder 1 and rotate with it. The linkage shaft 22 is used to install multi-wedge pulleys, sprockets, O-belts or synchronous pulleys and connects with a set of driven rollers to form a conveying or parking mechanism for palletized items or boxed materials. The other fixed end cap 2 is equipped with a connecting shaft 21, which is coaxial with the cylinder 1 and is used to fix the roller and connect it to the support. The connecting shaft 21 and the fixed end cap 2 are directly equipped with bearings so that the connecting shaft 21 does not rotate with the cylinder 1. It is also equipped with a conductive component for power transmission to stably introduce external power into the built-in motor 4.

[0023] Motor 4 is installed inside cylinder 1, and is coaxially mounted with connecting shaft 21 and cylinder 1, ensuring a compact overall structure and stable operation. A flange end cover 3 is provided at the end where motor 4 connects to connecting shaft 21. Both ends of flange end cover 3 are fixedly connected to connecting shaft 21 and motor 4 respectively, achieving stable assembly between motor 4 and connecting shaft 21. The output shaft 41 of motor 4 is connected to the input end of accumulation module 6, and the driving power is transmitted to planetary reduction module 7 after being regulated by the accumulation module.

[0024] The accumulator module 6 receives power from the output shaft 41 of the motor 4 and controls the engagement and disengagement of its internal clutch device 62 to switch the power on and off. The core component of the accumulator module 6 is a clutch-like mechanism, namely the clutch device 62. The clutch device 62 includes a drive assembly, a drive plate assembly, and a driven plate assembly. The drive plate assembly is connected to the output shaft 41 of the motor 4, and the driven plate assembly is connected to the reduction module 7.

[0025] The drive component adjusts the connection state between the active and driven disk components according to the control signal, thereby achieving precise power transmission or interruption. When the drive component receives an engagement signal, the active and driven disk components engage, transmitting power from motor 4 to reduction module 7, enabling motor 4 to drive cylinder 1 to rotate. When the drive component receives a separation signal, it stops operating, and the reset component separates the active and driven disk components, interrupting power transmission. Cylinder 1 can then rotate freely or stop without driving force, achieving material accumulation and pausing.

[0026] The power component of the drive assembly is generally an electromagnet, which is driven by an electronic control signal. During operation, it attracts the driven disk assembly and the driving disk assembly to fit together, thereby realizing the transmission of power torque.

[0027] like Figure 5As shown, the drive assembly includes an electromagnetic mounting plate 621, which is fixedly connected to the end of the motor 4. The electromagnetic mounting plate 621 has a cavity for mounting an electromagnet. When the electromagnet is energized, it generates an axial magnetic force, which pushes the driven plate assembly to move axially and press it against the driving plate assembly to achieve power transmission. When the power is off, the magnetic force disappears, the driving plate assembly separates from the driven plate assembly, and the power is cut off.

[0028] like Figure 5 As shown, the driving disc assembly includes a flywheel 623 and a friction plate 624. The flywheel 623 is fixedly connected to the output shaft 41 of the motor 4 via a key. The friction plate 624 is mounted on the end face of the flywheel 623 and rotates synchronously with the motor 4. When the electromagnet is energized, the driven disc assembly moves axially under the action of magnetic force and presses against the friction plate 624 to achieve torque transmission. When the power is off, it disengages, and the power is interrupted. The friction plate 624 is made of a high-friction coefficient material to enhance the transmission efficiency during meshing and reduce wear.

[0029] like Figure 5 As shown, the driven disk assembly includes an armature disk 625, a disc spring 626, and an output disk 627. The disc spring 626 is disposed between the armature disk 625 and the output disk 627 and is tightly attached to the output disk 627. The armature disk 625 and the output disk 627 are connected by a linkage pin 628, allowing the armature disk 625 and the output disk 627 to rotate synchronously and move relative to each other along the axial direction. Both ends of the linkage pin 628 have protruding structures, and the opposite sides of the protruding structures at both ends abut against the armature disk 625 and the disc spring 626, respectively. When the electromagnet is energized and generates magnetic force, the armature disc 625 overcomes the elastic resistance formed by the disc spring 626 and the linkage pin 628 under the action of magnetic force and moves towards the drive disc assembly until it is in close contact with the friction plate 624, realizing power transmission. When the power is off, the disc spring 626 releases its stored energy, pushes the linkage pin 628 to pull the armature disc 625 back, and separates the driven disc assembly from the drive disc assembly, realizing the rapid cut-off of power. This causes the cylinder 1 to lose its rotational torque, which facilitates the precise positioning or temporary storage of materials on the conveyor line, realizing the accumulation function.

[0030] Furthermore, the output end of the driven disk assembly is provided with a splined shaft, on which a splined sleeve 63 is fitted. An input gear 631 is located at the end of the splined sleeve 63 furthest from the splined shaft, and the input gear 631 meshes with the reduction module 7. During installation, axial sliding can achieve precise engagement between the splined sleeve 63 and the input gear 631, ensuring the stability and reliability of power transmission.

[0031] Furthermore, the accumulation module 6 also includes a housing 61, which is cylindrical and fixedly connected to the housing of the motor 4. The clutch device 62 is located inside the housing 61, and the drive component of the clutch device 62 is fixedly connected to the housing 61, so that the drive component and its electromagnet can be easily installed, and the conductive lines can also be led out through the reserved wire grooves inside each component to achieve reliable electrical connection.

[0032] Furthermore, the shell 61 has a groove on its cylindrical wall, which extends axially and passes through the end of the shell 61. The drive assembly has a locking block that can be inserted into the groove and slide in along its length. The mating structure of the locking block and the groove ensures accurate axial installation and circumferential fixation of the drive assembly within the shell 61, preventing rotational deviation during operation. The electromagnet's lead wire is led out to the external controller through a pre-set wire channel inside the shell 61, avoiding wear or interference from exposed wiring. Both the groove and the locking block have mounting holes to secure the locking block to the shell 61 with fasteners, facilitating disassembly and maintenance.

[0033] Furthermore, a flange end cover 3 is provided between the motor 4 and the connecting shaft 21. One end of the flange end cover 3 is fixedly connected to the connecting shaft 21, and the other end of the motor 4 is fixedly connected to the flange end cover 3, forming a rigid connection structure, which effectively improves the coaxiality of the transmission and the overall structural stability.

[0034] Furthermore, the reduction module 7 includes a planetary gear reduction mechanism. The input end of the planetary gear reduction mechanism is connected to the output end of the driven disk assembly, and the output end of the planetary gear reduction mechanism is fixedly connected to the inner wall of the cylinder 1. By utilizing the multi-point meshing characteristics of the planetary gears, the radial and axial stresses during the transmission process are effectively distributed. The modular direct current motor 4, the accumulation module mechanism, and the modular high-efficiency planetary reduction mechanism are organically combined to achieve a balance between high torque output and a compact structure.

[0035] Furthermore, the output end of the reduction module 7 is connected to an output disk 9, and the radial surface of the output disk 9 is provided with a connection structure for fixing to the inner wall of the cylinder 1. These connection structures include annular grooves 91, which are filled with elastic material to ensure an interference fit with the inner wall of the cylinder 1. This allows the motor 4 to transmit power to the cylinder 1 via the accumulation module 6, the reduction module 7, and the output disk 9, thereby realizing the accumulation function of the roller.

[0036] Furthermore, the output end of the reduction module 7 is provided with an output coupling disk 8. The output coupling disk 8 is fixedly and flexibly connected to the output disk 9 through an elastic element. This connection can ensure the coaxiality of the rotating drum, thus achieving a stable and low-noise output effect, while absorbing minor axial and radial deviations during the transmission process.

[0037] Power is supplied through an external controller. After the stator winding of motor 4 is protected and powered, the change in magnetic field causes the rotor of motor 4 to rotate, thereby causing the output shaft 41 of motor 4 and the active disc assembly of the clutch device 62 of the accumulation module 6 fixed at its front end to rotate. At this time, the cylinder 1 does not rotate, and the pallets or boxes on the entire roller assembly are in a stored and stopped state. When the pallets or boxes on the entire roller assembly need to be transported externally, the drive assembly of the internal accumulation module 6 is controlled, causing the active disc assembly and the driven disc assembly of the accumulation module 6 to push together, thereby driving the input gear 631 to rotate together. The input gear 631 drives the reduction module 7 to output to the output coupling disc 8 according to the reduction requirements. The output coupling disc 8 is fixedly and flexibly connected to the output disc 9 through a flexible pin. This connection can ensure the coaxiality of the roller rotating body and make its stable and low-noise output effect. The output disc 9 is fixedly connected to the cylinder 1, and finally the rotation of the cylinder 1 causes the driven roller assembly connected to it to rotate together, dragging the pallets or boxes on the roller assembly line. When pallet or box storage is required, the control drive assembly disengages the active and driven disk assemblies of the accumulation module 6 as needed. This causes the reduction module 7 to stop working, and the output coupling disk 8, output disk 9, and cylinder 1 connected to its rear end all stop working. Only the motor 4 rotates, achieving the purpose of storage and material handling.
