Description

Technical Field

[0001] This utility model relates to the field of express parcel sorting technology, and in particular to a sorting device based on direct drive swing. Background Technology

[0002] With the development of logistics automation technology, modular belt sorting equipment has emerged. This type of equipment can efficiently achieve bidirectional sorting of packages or items, improving the operational efficiency and flexibility of sorting centers.

[0003] In related technologies, to achieve the left and right deflection of the sorting wheel, a drive plate with a waist-shaped groove is usually set between the base plate and the machine base. The drive arm is driven by a motor, which drives the drive wheel to rotate within the waist-shaped groove, causing the drive plate to produce an offset motion symmetrical to the rotation center line of the sorting wheel. Finally, the deflection arm drives the sorting wheel to complete the bidirectional sorting operation.

[0004] However, the aforementioned driving method and related devices (including drive plate, drive wheel / bearing, etc.) have the following problems:

[0005] Firstly, the added drive plate and its necessary drive wheel or bearings place stringent requirements on the installation space of the motor and its surrounding components, especially taking up even more space in the already limited height space under the equipment, making layout difficult.

[0006] Secondly, when the module belt is running, there is a high risk of scratching between the module belt below the motor and the motor body or related drive components.

[0007] Third, the wear caused by the long-term reciprocating motion of the drive wheel or bearing in the slot not only increases the equipment failure rate, but also makes later maintenance more troublesome and costly. Utility Model Content

[0008] In response to the shortcomings of the existing production technology, the applicant provides a sorting device based on direct-drive oscillation, thereby improving the operational stability of the module belt sorting machine.

[0009] The technical solution adopted in this utility model is as follows:

[0010] A sorting device based on direct-drive oscillation includes:

[0011] Balance wheel module, balance arm module, motor module, and balance wheel bracket mounting plate;

[0012] The balance wheel module is mounted on the balance wheel bracket mounting plate via a mounting bushing, and the balance wheel can rotate within the bushing;

[0013] The swing arm module is located below the swing wheel bracket mounting plate and is connected to the swing wheel module by screws. A drive shaft is fixed to the swing arm module.

[0014] The motor module is fixed on the swing wheel bracket mounting plate and includes a motor, a rotating arm, and a bearing; the rotating arm is fixed to the motor output shaft, and the bearing is embedded in the rotating arm;

[0015] One end of the drive shaft is fixedly connected to the swing arm module, and the other end is engaged with a bearing;

[0016] The motor module of the sorting device directly drives the drive shaft through the rotating arm to drive the swing arm module to swing.

[0017] The swing wheel module includes at least one set of sorting swing wheels, whose rotation plane is parallel to the running direction of the module belt; when the motor drives the swing arm to swing, the top of the swing wheel of the swing wheel module contacts the bottom of the module belt conveyor wheel, generating a lateral frictional force, causing the items to move laterally, thereby realizing the sorting of items.

[0018] As a further improvement to the above technical solution:

[0019] In one embodiment, the drive shaft is clearance-fitted with the bearing, and the swing angle of the swing arm is synchronously transmitted to the swing arm module.

[0020] In one embodiment, the swing arm module includes a swing arm and a drive shaft, the drive shaft being disposed at the bottom of the swing arm and linked with the swing arm.

[0021] In one embodiment, when the motor output shaft drives the swing arm to swing, the drive shaft rotates by the same angle as the swing arm, thereby rotating the swing arm module.

[0022] In one embodiment, the motor module is fixed to the balance wheel bracket mounting plate by a single-headed hexagonal stud.

[0023] In one embodiment, the balance wheel support mounting plate is provided with mounting plate holes for removing the screws that fix the drive shaft for maintenance.

[0024] In one embodiment, a support wheel assembly is also included, disposed below the balance wheel bracket mounting plate, for supporting the smooth operation of the module belt.

[0025] In one embodiment, an electrical mounting plate is also included, fixed to the side of the balance wheel bracket mounting plate, for mounting the driver and arranging control lines.

[0026] In one embodiment, a set of motor modules drives at least one set of swing arm modules and a swing wheel module via a rotating arm.

[0027] The beneficial effects of this utility model are as follows:

[0028] This utility model has a compact structure. The motor shaft is directly fixed to the rotating arm, and the rotating arm has an embedded bearing that cooperates with the drive shaft. In the swing arm module, the drive shaft replaces the isolation column of the original swing arm and becomes the power transmission node. The transmission chain is simplified to motor → rotating arm → drive shaft → swing arm, which reduces sliding friction pairs and reduces wear. Attached Figure Description

[0042] This application provides a sorting device based on direct drive swing, including: a swing wheel module 1, a swing arm module 2, a motor module 3, and a swing wheel bracket mounting plate 4;

[0043] Among them, the balance wheel bracket mounting plate 4 serves as a load-bearing base, and an electrical mounting plate 6 is fixed on its side for installing the driver and arranging the control circuit.

[0044] The balance wheel module 1 is directly clipped onto the balance wheel bracket mounting plate 4 via a mounting bushing, and the balance wheel can rotate within the bushing.

[0045] The swing arm module 2 is located below the swing wheel bracket mounting plate 4 and is fixed to the swing wheel module 1 by screws. One end of the drive shaft 12 is fixed to the swing arm module 2.

[0046] The motor module 3 is fixed to the lower surface of the balance wheel bracket mounting plate 4 by hexagonal studs 9;

[0047] The balance wheel module 1 includes at least one set of sorting balance wheels, the plane of which rotates parallel to the running direction of the module belt.

[0048] In some embodiments, the swing arm module 2 includes multiple swing rods 11, which are connected to form a frame structure by isolation columns; the isolation column at the bottom of one of the swing rods 11 is replaced by a drive shaft 12, the lower limit of the drive shaft 12 is locked on the connecting rod, its top end is fixed to the upper surface of the swing rod 11 by screws, and its bottom end extends to the linkage position of the motor module 3.

[0049] In some embodiments, the motor module 3 includes:

[0050] The motor body is positioned by the motor mounting plate 5;

[0051] The rotating arm 13 is rigidly fixed to the end of the motor output shaft;

[0052] The bearing 14 is embedded in the shaft hole at the end of the rotating arm 13 and forms a clearance fit with the bottom end of the drive shaft 12;

[0053] A bearing limiting plate is provided on the outer side of bearing 14;

[0054] The transmission path of the motor torque is as follows: motor shaft → rotating arm 13 → bearing 14 → drive shaft 12.

[0055] In some embodiments, during actual maintenance, the drive shaft 12 can be quickly disassembled and assembled by removing the fixing screws through the mounting plate hole 10.

[0056] In some embodiments, the support wheel assembly 7 is mounted on the bottom edge of the balance wheel bracket mounting plate 4 to support the smooth operation of the module belt.

[0057] In actual work, the sorting process includes:

[0058] In standby mode, the balance wheel rotation plane of the balance wheel module 1 is parallel to the running direction of the module belt, and the support wheel assembly 7 supports the module belt to run smoothly.

[0059] Sorting is triggered, and the motor receives the command to drive the rotating arm 13 to deflect at a set angle (preferably ±45°);

[0060] Power transmission: the drive shaft 12 rotates synchronously with the rotating arm 13 through the bearing 14, causing the swing arm module 2 to swing as a whole.

[0061] Friction sorting: the swing wheel module 1 deflects accordingly, and the top of its swing wheel contacts the bottom of the module belt conveyor wheel, generating a lateral friction force that causes the items to move laterally, thus achieving precise sorting.

[0062] like Figure 5 As shown, in a specific embodiment, for example, a group of motor modules 3 simultaneously drive four symmetrically distributed swing arm modules 2 and swing wheel modules 1 through the rotating arm 13 to ensure the synchronicity of the sorting action.

[0063] In summary, the structure of this utility model is reasonable. The motor shaft is directly fixed to the rotating arm 13, and the rotating arm 13 has an embedded bearing 14 that cooperates with the drive shaft 12. In the swing arm module 2, the drive shaft 12 becomes the power transmission node, simplifying the transmission chain.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
