Solution for loading and unloading system of truss machine tool

Solution for loading and unloading system of truss machine tool

Openness, convenience, and humanization

The truss manipulator has a fast pace, high efficiency, and can basically meet the speed requirements of most machine tools for loading and unloading. It can achieve "hand waiting for machine tool".

Industry background

The rise of automated machine tool loading and unloading has solved the problem of manual loading and unloading of machine tools: the machinery does not need to rest halfway and can process continuously for 24 hours. A worker can simultaneously supervise 8-10 machines, saving a lot of labor costs. No manual labor is required to enter the equipment for loading and unloading, workers only need to organize the material tray, avoiding personal injury.

At present, it is mainly used in lathes, grinders, and a small number of non-standard machines with truss mechanisms.

The truss manipulator has a fast pace, high efficiency, and can basically meet the speed requirements of most machine tools for loading and unloading. It can achieve "hand waiting for machine tool".

System principle

The robotic arm first reaches the safe position and performs fixed-point/code wheel picking of the raw material. After the machine tool allows material replacement, the robotic arm carries the raw material into the interior of the machine tool, removes the finished product and puts it into the raw material, and then moves out of the machine tool processing area. The machine tool starts processing, and at the same time, the robotic arm carries the finished product for fixed-point/code wheel feeding.

Control solution

The loading and unloading system of the truss machine tool is divided into two types: bus control scheme and pulse control scheme:

The bus control scheme has the advantages of high accuracy, position recording during power outages, simple wiring, and strong anti-interference.

The pulse control scheme has high adaptability and can be adapted to other mainstream servo products in the market.

The system adopts block based programming, where instructions are directly inserted into the programming window and displayed in block based format. The program flow is fully visible, making it easy for customers to check and modify errors.

By using the three-point demonstration method and matrix operation, each position of the workpiece on the code wheel can be accurately located.

Adopting intra task optimization instructions, opening up instructions that can run in parallel, supporting up to four tasks, and executing tasks in parallel.


Solution advantages

Higher openness

IO definition: Customers can configure IO definitions according to their actual needs, and can also choose whether to add external expansion modules. Program editing: The process program can be changed on the teaching pendant, easy understanding and high efficiency. Interaction method: For editing tasks that cannot be completed by the teaching pendant, ladder diagrams can be added to the PLC for interactive collaboration.

Better convenience

Program debugging provides rich premade functions and instructions, which can be directly written or referenced.

After sales maintenance

Simple operation method, conducive to terminal understanding, reducing maintenance troubles.

Process transplantation

Directly import and export from USB flash drive, quickly transplant and handle multiple sets of equipment.

Safety performance

Development area protection, hard limit protection, soft limit protection to avoid automatic and manual collision, and solve the problem of misoperation of the robotic arm after entering the machine tool.

Special process

Develop a wide range of blowing and oil pump functions for customers, which can achieve timed blowing and refueling.

Logical execution method

Develop a jump method based on stacking, signaling, and frequency as conditions.

Diversification of code disks

Open two groups, each with a large capacity stacking setting of twelve bits.

IO configuration

Based on industry characteristics, integrate commonly used IO names, and customers can directly configure IO for the names to reduce typing.
