Automatic control system for quantitative packaging multi-head combined scale

Abstract

The invention relates to the technical field of intelligent control, in particular to an automatic control system for a quantitative packaging multi-head combined scale, and the system collects multiple frames of material images through an image collection module; obtaining a binary image of a change area of two adjacent frames of material images through an image processing module, identifying a plurality of connected domains of the binary image, and obtaining a corresponding center point coordinate; obtaining an image partial region corresponding to each connected domain; obtaining the circle center of an outlet of the collecting tank; taking each connected domain as a target connected domain through a position approximation acquisition module, and acquiring the position approximation of the target connected domain and the same alternative connected domain; obtaining the matching degree of the target connected domain and the same alternative connected domain through a matching degree obtaining module; and the blanking interval time of different combined hoppers is controlled through the automatic control module. According to the invention, the blanking interval time of different combined hoppers of the multi-head combined scale can be adjusted in a self-adaptive manner, and blanking is carried out at the highest speed on the premise of ensuring no blockage.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to an automatic control system for a quantitative packaging multi-head combination scale. Background technique [0002] With the continuous improvement of the degree of mechanical automation, when the material is produced in the factory, it is necessary to use a multi-head combination scale to automatically discharge and complete the quantitative packaging. However, due to the irregularity of the material body of some materials and the large volume, such as walnuts, jelly, etc., if they are discharged at the same time, they may accumulate at the discharge port and cause blockage, so it needs to be discharged in batches. [0003] When the combination bucket is weighed in the batch unloading operation, the combination buckets are discharged after a certain interval of time, and the interval discharge time of each combination bucket is debugged by human experience or preset...

Problems solved by technology

However, due to the irregular and large volume of some materials, such as walnuts, jelly, etc., if they are discharged at the same time, they may form accumulations at the discharge port and cause blockage, so batch discharge is required

[0003] When weighing combined hoppers in batch feeding operation, each combined hopper is discharged after a certain time interval, and the interval discharge time of each combined hopper is a human experience adjustment or a preset parameter, resulting in inability to discharge according to Adjust the specific production requirements, or when producing for different materials, the control time of batch cutting corresponding to different materials is different, and the determined parameters cannot be directly used as the interval time
