Description

Horizontal adjustment device and application method of circular sorter based on "I"-shaped structure

technical field

The invention relates to the technical field of logistics sorting, in particular to a horizontal adjustment device for a circular sorter based on an "I"-shaped structure and an application method thereof.

Background technique

With the rapid development of the e-commerce era, it has also promoted the transformation of the logistics industry. Automated equipment has gradually replaced manual sorting by operators. This situation has higher and higher requirements for logistics automation equipment, and a large number of sorting machines have emerged. Devices, such as: circular sorter, linear cross-belt sorter, double-deck circular cross-belt sorter, etc.

The existing circular sorter will have the following problems during operation:

(1) There is only one contact surface between the driving device and the sorting platform, which is easy to generate gaps and the driving force is unstable;

(2) The driving device and the load-bearing device are integrated, and it is prone to vibration and relative sliding during its operation, which cannot guarantee its levelness, and at the same time, long-term operation reduces its service life;

(3) The fixed support force of the sorting platform is provided by the universal joint located in the center, and the relative position will change during the operation, and there is no limit device.

The existence of the above problems restricts the sorting efficiency of the circular sorter, and cannot meet the requirements of enterprises for logistics sorting.

In 2014, Wang Aili and others invented a level adjustment device (authorized announcement number: CN103964310B). Blue screw and vertical moving mechanism, so by adjusting the turntable screw and vertical moving mechanism, the height position of the connection between the equipment and the horizontal adjustment mechanism can be changed, and the level of the equipment can be adjusted by separately adjusting multiple horizontal adjustment mechanisms The purpose; its shortcoming is that when the level error exceeds the adjustment range of the level adjustment device, it is necessary to manually adjust the level mechanism so that the piston rod is adjusted and reset and then re-leveled.

In 2016, Fang Jiasen invented an automatic level adjustment device (application publication number: CN106774448A), which has the advantage of not only realizing automatic level adjustment, but also overcoming the defect of high difficulty in manual adjustment, and ensuring the accuracy of adjustment The degree has laid a reliable foundation for the proficiency test and improved the accuracy of the test results. The disadvantage is that in the process of adjusting the levelness, the first test board will have a gap with the box under the drive of the motor. At this time, sundries may enter the box, which may cause damage to the components inside the box.

In 2016, Daniel Kremel and Christian Deutsch invented a level adjustment device (authorized notification number: CN108349511A). The advantage is that the level adjustment device is composed of a suspension unit, which is set on the track Between the bogie and the car body of the vehicle, and are respectively composed of spring, pneumatic or hydraulic reciprocating piston elements. According to the invention, the reciprocating piston element is retracted in driving operation so that it does not straddle the distance between the car body and the bogie; the disadvantage of this is that the spring deforms after a period of use resulting in insufficient elasticity and thus becomes slack, There is an error in the level adjustment.

In view of the above problems, and compared with the existing technology, a circular sorter level adjustment device and its application method based on the "I" shape structure are designed.
