Technical Field

The invention relates to a sorting method of an improved connecting rod balance wheel sorting machine, which is a supplementary improvement of an electric connecting rod balance wheel sorting machine and a swing control method thereof, and belongs to the field of logistics storage, wherein the supplementary improvement is provided by the prior application of the applicant of CN 201910895675X.

Background

Currently, in logistics storage and transportation, the equipment for sorting goods usually comprises a balance wheel sorting machine. The balance wheel sorting machine is controlled in steering mode according to different sorting or conveying directions of goods, and the goods are conveyed to different outlets through the steering drive of the swing mechanism while being conveyed in a self-rotating mode through the balance wheels, so that the sorting function is achieved.

The prior sorting machine adopting a connecting rod type transmission mechanism cancels the transmission mode of a traditional gear and rack structure. The sorter comprises a frame arranged on a conveying line, a plurality of sorting assemblies distributed in rows and columns, a transmission mechanism for providing driving force for the sorting assemblies in the conveying direction and a swing driving mechanism. The swing driving mechanism comprises a servo motor, at least one group of first connecting rods and a plurality of groups of second connecting rods, wherein the servo motor, the at least one group of first connecting rods and the plurality of groups of second connecting rods are arranged along the conveying direction; the servo motor is simultaneously connected with each group of first connecting rods in a driving way; each group of first connecting rods is connected with a column of sorting assemblies, and each group of second connecting rods is connected with a line of sorting assemblies.

The prior applications have the disadvantages that firstly, because a two-layer crossed link mechanism is adopted, namely the link mechanism is driven by a first link rod in the conveying direction and driven by a second link rod in the direction perpendicular to the conveying direction, the swing driving force of the two-stage transmission consumes a large amount in the transmission process, a motor with large output power is required to be equipped, the energy consumption is increased, and the noise is large; secondly, due to the two-layer cross transmission connecting rod driving mode, after long-time use, the gap between the first connecting rod and the second connecting rod is enlarged due to abrasion, so that the force transmission is deviated, the accuracy of the swinging direction and the angle is directly influenced, even wrong sorting results occur, and extra workload is brought to the subsequent equipment maintenance and overhaul; thirdly, the structure of the transmission mechanism and the swing driving mechanism is still complex, which is not beneficial to reducing the requirements on the precision of part processing and equipment debugging. Under the complicated working environment condition of current sorting machine, still higher to the sealed requirement of balance wheel self structure, later maintenance still shows loaded down with trivial details with the maintenance.

In view of this, the present patent application is specifically proposed.

Disclosure of Invention

the protruding shaft bearing at the far end of the self-lubricating bearing rotates in the transverse through groove and horizontally pushes the transition steering rod at the same time, so that synchronous horizontal displacement of the array reversing rods is realized.

a roller is arranged in parallel vertically below each row or each row of the balance wheel modules, and a plurality of O-shaped belts which are respectively connected with the balance wheels of each balance wheel module are sleeved on each roller.

In summary, the sorting method of the connecting rod balance wheel sorting machine has the following advantages:

1. by adopting the swing driving mechanism and the method of single-layer linear transmission, the swing control precision and the operation efficiency are effectively improved, and meanwhile, the loss and the noise of the transmission force are obviously reduced.

2. The synchronous performance of the swing drive is improved, the number of connecting parts is correspondingly reduced, and the manufacturing cost is reduced.

3. Respectively optimizes the structure and connection of the transmission power unit and the swing drive unit, and improves the drive response speed

Meanwhile, the cost control and the use efficiency of the whole sorting machine equipment can be facilitated.
