Control System Design for Catering Collecting Robot Based on PLC

摘要:

针对当前餐厅收餐自动化水平低下的现状,提出了自动化收餐流水线的概念,设计了一款收餐机器人;在分析收餐机器人整机结构和运动要求的基础上,进一步设计了一种基于PLC的收餐机器人控制系统;系统主要由餐盘翻转模块、筛选模块、餐具输运模块、餐盘堆叠模块和残渣收集模块组成;根据不同模块的工作流程和作业需求,以西门子S7-200为控制系统核心,完成了系统的软硬件设计,并分别对各模块进行了编程调试,可实现精确的位置控制,符合实际控制要求,达到自动收餐的目的。

Abstract:

As present catering collecting automation level is low, a notion of automated catering collecting assembly line is put forward and a catering collection robot is designed. After analyzing the whole structure and motion requirements, a further control system for catering collecting robot based on PLC is designed. It is mainly divided into serving tray rotating module, filtering module, tableware conveying module, serving tray stacking module and residues collecting module. Considering different working process and control requirements between modules, this paper applied Siemens S7-200 as the core of control system, finished hardware and software design, made programs and debugged for each module, and achieved accurate position control, which meets actual control requirements and can collect serving tray automatically. 
