Application of TLS Servo Control System in Robot Palletizer

01  Industry Background

Robot palletizer, a kind of robot for humanoid operations, automated control, energy conservation and environmental protection, can be utilized for the stacking of different types of materials. A robot palletizer consists of the mechanical body, servo drive system, arm, end effector and its posture control mechanism and testing structure. As one of the core components for the robot palletizer, the servo control system provides most of the power, and a highly cost-effective servo control system decides the reliability and stability of the robot palletizer.

Currently, robot palletizers used in China are mostly manufactured by domestic manufactures compared to other kinds of robots, but their key spare parts still rely on imported ones, thus affecting the competitiveness of domestic robot palletizers.

02  User Demand

An intelligent equipment supplier from Hefei, Anhui has been using a servo control system developed by a Japanese brand. As the industry competition intensifies, enterprises are faced with growing costs. In order to effectively control costs, this user began to seek for an appropriate domestically developed servo control system and get rid of the dependence on imported high-priced servo control systems.

03  Solution

  1. Working principle

Robot Palletizer places the materials in containers or packed and unpacked regular items on the trays in a sequence. Automatic stacking is made for multiple layers. Then, the materials or items are pushed out for packaging or being delivered to the warehouse by forklifts, especially suitable for dangerous operations or posts with repeated or laborious work.

 

  1. Overview

Based on years of technical accumulation and rich research, development and application experience in electrical control, our TLS Servo team proposed a complete set of system solution to guarantee handling speed and reliability and lower costs based on the characteristics of robot palletizer.

  1. Features

  • Optimal control design
    TLS Servo Control System comes in optimized control model, rapid computation, and higher reliability after being configured with Googol Tech control system; also, it provides a solid technical foundation for rapid and stable operations based on mechatronics control platform and optimal mechanical properties.

  • Faster handling speed
    Our system has been equipped with optimal motor and drive matching performance, whose handling speed increases by 50% compared with the servo control system of a Japanese brand. Moreover, it has excellent acceleration and deceleration performance, and meets the requirements for high speed and stable operation.

  • Higher reliability
    Based on the operational characteristics of robot palletizer, by taking into full account the allowance design of servo control system, the handling speed is enhanced while achieving stable output, providing more reliable power support for robots.

04   Application Effects

The TLS Servo Control System designed for the robot palletizer industry is highly cost-effective and reliable in terms of system control design, handling speed and reliability, compared with servo control systems of other brands.

Although robot palletizers can be domestically manufactured, the whole machine is still high-pried because core components in the servo control system are still imported from other countries. Our system not only reduces the user’s overall costs, but also helps to improve whole machine performance and increase the enterprise’s competitive edges. Thus, they can further expand their market share.
