[0021] When the utility model is in use:

[0022] Since there are usually several balance wheel modules on a tilted balance wheel sorting machine, nine balance wheel modules are taken as an example here. The nine balance wheel modules are distributed in a rectangular shape, with the longitudinal direction as the default moving direction of the objects to be sorted, and the transverse direction as the sorting direction of some objects to be sorted. When working, the stepper motor drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the rubber wheel B6 to rotate and then drives the rubber wheel A5 to rotate, and then the working roller 3 rotates, driving the objects to be sorted to move in the longitudinal direction; when it is necessary to sort the objects to be sorted in the transverse direction, the servo motor drives the driving shaft 13 to rotate through transmission or directly, so as to Figure 1 For example, at this time, the active turntable 12 needs to rotate one cycle in the clockwise direction, and the driven turntable 11 is turned 90 degrees in the counterclockwise direction, and the balance wheel module rotates 90 degrees, so that the sorting in the horizontal direction of 90 degrees is realized. At this time, the rotation angles of all the balance wheel modules are the same and are all 90 degrees. When it is necessary to return to the default sorting direction, the servo motor controls the active turntable 12 to rotate one cycle counterclockwise, and the driven turntable 11 drives the balance wheel module to rotate 90 degrees clockwise to return to the default longitudinal sorting direction;

[0023] If flexible sorting of objects to be sorted is to be achieved, the number of pin slots 1102 of the driven turntable 11 needs to be changed. Taking nine balance wheel modules as an example, the nine balance wheel modules are distributed in a rectangular shape, with the longitudinal direction as the default moving direction of the objects to be sorted, and the transverse direction as the sorting direction of some objects to be sorted. When working, the stepper motor drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the rubber wheel B6 to rotate and then drives the rubber wheel A5 to rotate, thereby rotating the working roller 3 to drive the objects to be sorted to move in the longitudinal direction. When the objects to be sorted need to be sorted in the transverse direction of 90 degrees, two types of groove wheel mechanisms are used here to achieve flexible sorting, one of which is a groove wheel mechanism with four pin slots, that is, Figure 5The grooved pulley mechanism shown, and the other is the grooved pulley mechanism with six pin grooves, that is, when the driving turntable 12 rotates one cycle, the grooved pulley mechanism rotates 60 degrees. Among the nine pendulum wheel modules, the two rows close to the initial position of the object to be sorted are the grooved pulley mechanisms with six pin grooves, and the row in the deepest longitudinal direction is the grooved pulley mechanism with four pin grooves; during operation, a servo motor drives the driving turntable shaft 13 to drive the two rows of grooved pulley mechanisms with six pin grooves to rotate. When the driving turntable 12 rotates one cycle, the two rows of grooved pulley mechanisms with six pin grooves only rotate 60 degrees. Another servo motor drives the driving turntable shaft 13 to drive one row of grooved pulley mechanisms with four pin grooves to rotate. When the driving turntable 12 rotates one cycle, this row of grooved pulley mechanisms with four pin grooves rotates 90 degrees. This gives the object to be sorted a buffer angle when it is about to turn. The row of grooved pulley mechanisms with four pin grooves in the deepest longitudinal direction ensures that it will finally move in the 90-degree horizontal direction, reducing the possibility of the object tumbling and being damaged and improving the sorting efficiency; when it is necessary to return to the default sorting direction, the two servo motors control the driving turntable shaft 13 to rotate counterclockwise one cycle, and the grooved pulley with four pin grooves and the grooved pulley with six pin grooves drive the pendulum wheel module to rotate clockwise by 90 degrees and 60 degrees respectively, returning to the default longitudinal sorting direction.

[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
