Conveying device

Abstract

The invention discloses a conveying device. The conveying device comprises a machine frame, wherein a plurality of rows of conveying wheels are arranged on the machine frame in an equal-height mode, axes of all the conveying wheels are parallel to one another and are parallel to the horizontal plane, each conveying wheel can be arranged on a support in a rotation manner around the axis of the correspondingly conveying wheel, and the supports on which each row of conveying wheels are located are arranged on one supporting rod fixed on the machine frame. According to the scheme, the design is ingenious, the structure is simple, each row of conveying wheels are located on one independent supporting rod, therefore gravity borne by each supporting rod can be effectively reduced, the problem that all conveying wheels in an existing structure are located on the same supporting plate so as to easily cause deformation of the supporting plate is effectively solved, the stability of the integralstructure and the accuracy of conveying positions are ensured, and the effectiveness and the reliability of conveying are effectively improved.

Description

technical field [0001] The invention relates to the field of sorting equipment, in particular to conveying devices. Background technique [0002] With the rapid development of modern logistics, the requirements for logistics automation equipment are getting higher and higher. In the automation system of modern logistics, sorting machines are used more and more. At present, there are many types of sorting machines, and the sorting efficiency of different sorting machines is also very different. The common automatic sorting machines include cross-belt sorting, slider sorting, deflection wheel sorting and so on.

Problems solved by technology

[0003] Among them, the deflection wheel conveying line is a kind of equipment that realizes the conveying and turning of the items on it through the rotation and horizontal rotation of multiple independent spheres or wheels. However, in the attached figure 1 In the existing structure shown, multiple deflection wheels are set on the same support plate. After using for a period of time, it is found that the conveying position accuracy of the conveying wheel type often deviates

After a lot of research by the inventors, it was found that the reason for this problem is that: due to the multiple deflection wheels on the support plate, it has been under heavy load conditions for a long time, so a slight deformation has occurred, that is, it appears as a concave surface. As a result, the position of the deflection wheel in the middle area sinks slightly, which causes a deviation in the delivery position that should have been achieved, which not only increases the difficulty of control, but even causes a problem that it cannot be used at all.

[0004] In addition, in the existing drive structure that drives the deflection wheel to rotate horizontally, the synchronous wheel and synchronous belt transmission or gear transmission are often used, but in the synchronous belt and synchronous wheel transmission mode, the synchronous belt is prone to breakage due to long-term use. The situation affects the stability and service life of the equipment, and the installation of the synchronous belt requires a certain space requirement, which increases the design difficulty of other structures, and at the same time the maintenance cost is high; while the gear transmission method requires multiple gears to mesh, And through the transmission of multiple transmission rods, the consistency of action between multiple transmission rods is often not guaranteed, and the gears are prone to tooth skipping. Once the tooth skipping occurs, the deflection ball in a certain area will not be able to deflect, causing the entire conveying The work of the line fails, which seriously affects the stability of the conveying
