Bar feeding system for thread rolling machine

The bar feeding system for thread rolling machine is an optimal solution for businesses looking to reduce production costs in large-scale mass production. With a high level of automation, the system optimizes the part handling process and ensures that the finished products maintain consistent quality and dimensions. Compared with manual labor, implementing an automatic feeding system for a thread rolling machine provides an effective replacement, as the system can operate continuously for up to three shifts per day. So, how does this system operate, and what applications does it offer in manufacturing? Let’s explore these outstanding features with CNC VINA in the article below!

Technical specifications of automatic bar feeding system for thread rolling machines.

Structure and operating principle of thread rolling machine bar feeding system

The bar feeding system for thread rolling machine is designed to automate the process of feeding products into the machine, removing finished products, and transferring them to the next production stage. The system integrates conveyors, positioning mechanisms, transfer grippers, and inspection sensors, ensuring continuous, accurate, and synchronized part feeding with the operating cycle of the thread rolling machine.

Structure of the automatic part feeding system for the thread rolling machine

The automatic part feeding system consists of the following main units:

• Product level input conveyor assembly
• Transfer cluster (cluster 1 and cluster 2): product supply cluster for the lathe + product pick-up cluster combined with automatic robot.
• Intermediate cluster
• Upper and lower cover clusters
• Ouput cluster

Principle of operation

• The input conveyor moves the product step to the product positioning position (with sensor to check the product)
• Cylinder 1 goes up to locate the product (There is a sensor to check the product after positioning)
• The transfer robot's pick-up arm goes down to clamp the product (There is a sensor to check whether the product is clamped or not)
• The product is picked up and moved and dropped into the thread rolling machine
• The transfer robot will wait after the thread rolling machine finishes processing and will continue to move its hand down to pick up the product
• The transfer robot arm will rotate 90 degrees and move to the product drop position on the output conveyor.
• Then the transfer robot arm will move to the input conveyor and wait to pick up the product
• On the output conveyor, each compartment contains 2 products. After there are 2 products on the conveyor, the conveyor will move step by step.

Outstanding features of the automatic bar feeding system for thread rolling machines

The automatic part feeding system for the thread rolling machine is designed to automate the entire process of feeding parts into the machine, removing finished products, and transferring them to the next production stage. The system integrates conveyors, positioning mechanisms, transfer grippers, sensors, and a PLC control system, ensuring continuous, accurate, and synchronized operation with the machining cycle of the thread rolling machine.

- The automatic part feeding system for the thread rolling machine replaces manual operations performed by workers with an automated transfer mechanism and gripping arm. Parts are conveyed from the input conveyor to the positioning area, then picked up and accurately loaded into the thread rolling machine. Once machining is completed, the finished product is automatically removed and transferred to the output conveyor or the next production stage.

- The system is designed to reduce waiting time between machining cycles, with a cycle time of approximately 13 seconds per product. This enables more efficient utilization of the thread rolling machine's designed capacity and makes the system suitable for mass-production lines.

- Sensors are integrated at critical positions throughout the part feeding process. The system can detect the presence of a part after it reaches the positioning area and verify whether the transfer gripper has correctly clamped the product before moving it. This helps prevent missing parts, incorrect gripping, or improperly positioned products from being loaded into the machining machine.

- The transfer robot operates synchronously with the machining cycle of the thread rolling machine. After loading the part into the machine, the gripping arm waits until the machining process is completed, then automatically removes the finished product and transfers it to the output position.

- The system uses a PLC combined with a touchscreen HMI to control and monitor operation. Operators can monitor the system status, perform operating functions, and support troubleshooting when issues arise during production.

- Automating the part feeding and product unloading processes reduces the company's dependence on manual labor, particularly in high-volume production. Workers can focus on inspection, system monitoring, and production line management instead of continuously performing manual loading and unloading operations.

- The processes of part feeding, positioning, gripping, and unloading are carried out according to a programmed sequence, minimizing variations caused by manual operations. As a result, the system helps maintain production stability and supports better product quality control in mass-production machining lines.

- Instead of using a fixed configuration for every application, the automatic feeding system can be designed and customized according to the product size, shape, required production capacity, cycle time, and actual factory layout. CNC VINA can integrate input/output conveyors, transfer robots, positioning mechanisms, and intermediate units to meet specific automation requirements.

- In addition to feeding parts into a thread rolling machine, the system can also be designed to transfer finished products to an output conveyor or the next machine tool, creating a continuous production sequence. This provides a foundation for building an automated machining line while minimizing intermediate handling between production stages.

Operating instructions and dandory

Basically, the process and operation and maintenance of the bar feeding system for thread rolling machines are similar to the automatic bar feeding system of CNC lathes.

However, additional attention should be paid to the troubleshooting process in the following cases:

After pressing EMG due to problem : Release all EMG, switch switch to MANUAL. Press RETURN to initialize the run again.

Cylinder stroke error: Check the air supply, check if the cylinder is stuck. Tighten the light cylinder LS position. Reset clears the error then press Start to continue running.

Robot overload error: Check if the robot is stuck. Re-align manually. Try pressing Reset to reset the error. If not, turn off the master circuit breaker to reset the robot. Initialize and run again from the beginning.

Engine overload error: Check the engine, find the cause of overload and handle it. Turn off the power and start again.

When performing the above solutions but the error cannot be resolved:

+ Check if the device's wiring connection is loose, broken or slipped.

+ If not, check the device again to see if it still works.

– In case the running machine has an error that cannot be handled:

+ Press and hold the "STOP" and "RESET" buttons simultaneously for 2 seconds until the STOP light lights up and the RESET light flashes to return the system to the initial initialization.

+ If you cannot handle it, you must turn off the power to the entire system, then re-supply the power and restart from the beginning.

The bar feeding system for thread rolling machine offers numerous outstanding benefits, helping improve production efficiency and minimize errors during operation. With its high level of automation, the system not only optimizes part handling time but also ensures the accuracy and consistency of finished products. This is particularly important in the mechanical manufacturing industry, where strict requirements for quality and productivity are essential. In addition, the application of automation technology helps reduce labor costs while creating a safer working environment for operators. Thanks to these advantages, automatic part feeding systems are becoming an increasingly popular solution in modern production lines. If you are interested in an automatic part feeding system for a thread rolling machine, please contact CNC VINA today for detailed consultation and the most suitable solution for your production needs.
