Sorting method for carbel loop line sorting system and package discharging control system

Abstract

The invention discloses a sorting method for a carbel loop line sorting system and a package discharging control system. The sorting method comprises the following steps: S1, a package supply line reserves a sorting trolley and supplies a package to the sorting trolley determined by the reservation, and the control system does not stop a first adjusting line and a second adjusting line from completing package loading after the sorting trolley is reserved and determined for the package through a light curtain; and S2, after the package is successfully loaded on the sorting trolley, the control system controls the sorting trolley to start discharging the package at a package discharging cell opening corresponding to the package. The sorting method for the carbel loop line sorting system and the package discharging control system have the advantages that the design is elaborate and the process is simple. According to the sorting method, the center of mass of the package is determined by the light curtain so that the trolley can be reserved according to the distance from the center of mass to the package loading point, the speed change time point and the target speed of the first adjusting line and the second adjusting line are adjusted according to the position of the trolley, no sections need to be stopped in the whole package conveying process, and therefore time loss caused by stop is avoided, the sorting speed can be increased, and the sorting efficiency can be improved.

Problems solved by technology

[0011] The current algorithm still has an error, which is the error on the acceleration section. When the speed difference between adjacent acceleration sections is less than 0.5m / s, it has little effect on the standard package, but it has a great impact on the package with uneven mass density, resulting in The level of preparation for loading is low. In order to ensure the consistency of the loading positions of different packages, we must reduce the speed difference between adjacent acceleration sections. In this way, when the speed of the main loop is high, it is required to have many sections of speed regulation, or to lengthen the speed regulation The section enables the acceleration section to receive the package smoothly and then accelerate, and then send it out smoothly

[0012] According to the existing control method, when the friction coefficient is small, the start-stop section must be longer so that the length of the package can be stopped plus the length accelerated to the fixed speed of this section plus the maximum size of the package, increasing the package table Floor area

[0013] In addition, the unpacking process is also an important process of the parcel sorting machine, which directly affects the performance and efficiency of the entire parcel sorting machine. The existing unpacking control method has a complex algorithm, a relatively long calculation process, and low efficiency.

[0014] Moreover, the existing algorithms are greatly affected by the actual physical structure of different cross-belt loop sorting systems, and have poor applicability and stability.

[0015] At the same time, the existing algorithm cannot be adjusted according to the size of the package. For some oversized or long packages, due to the longer time from the sorting trolley, the sorting trolley is started at the same point, and the parcel may not be delivered in time. The problem of conveying into the sorting port, causing the package to be damaged
