Solution for Bag Spring Machine System

High speed, efficient and stable production, flexible manufacturing for quick adjustment

Early spring bagging machines were produced in conjunction with motors and cylinders, and the spring forming, conveying, and packaging actions only started after the previous action was completed, resulting in low production efficiency. The new model adopts an electronic cam control scheme, with reasonable planning of action coordination. Actions can be interspersed, effectively improving production efficiency. Moreover, a single model can quickly adjust electronic cam parameters to produce springs of different specifications.

Industry background

Spring machines mainly produce Simmons spring mattresses. With the improvement of living standards, people's requirements for furniture are gradually increasing, and furniture factories are gradually upgrading from price competition to quality competition.

System principle

The self rotating wire feeder heats the steel wire, and the wire feeding wheel squeezes and bends the preheated steel wire through the machine head to produce springs. After being compressed by the packaging part, it is sent into non-woven fabric and ultrasonically welded into independent bagged springs, completing the spring components of the Simmons mattress. The action process is assisted by 10 servos. The spring forming is completed by the cooperation of the wire feeding motor and the forming shaft motor. The conveying motor sends the spring to the bagging position and completes the cooling and shaping. Then, the compression shaft and compression chain work together to compress the spring. Two small chains put the spring into the bag, and the non-woven bag is packaged by the large mold servo and small mold cylinder. The finished product is then sent out by the pull-down shaft.

Solution advantages

Tight Actions, Efficient Production,

Optimize the curves of each axis according to customer requirements, ensure tight coordination of each axis action, and achieve high production efficiency.

High-Speed and Smooth Operation, No Vibration

During high-speed operation, all axes run smoothly and there is no vibration during start stop.

Cam Curve with Gentle Actions

Plan special cam curves in areas with mechanical collisions to soften movements and reduce noise.

Flexible Alarm System

By adding a flexible alarm system, the machine can be stopped in a timely manner in case of spring jamming, avoiding mechanism jamming and making fault clearing more convenient. The alarm value can be set, and customers can adjust the alarm sensitivity according to their own requirements.

Quick Cam Position Adjustment,

It can quickly adjust the cam point position, adjust the spring shape to produce products of different specifications, and facilitate action planning and coordination modification. It can be quickly modified according to customer model changes.

Bus Control for Higher Precision

EtherCAT bus control provides faster instruction cycles and higher accuracy. Using DS5C synchronous motor, it has high rigidity response and can ensure responsiveness even at high speeds, achieving stable operation.

All-Servo Single-Line Spring Machine for Efficient and Stable Production

The fully servo single line spring machine with three servos in the head section, completely abandoning mechanical camshafts. The spring shape is controlled by servo motors, with a stable production rate of 180 pieces/min, and can produce special packaging products.

All-Servo Dual-Line Spring Machine for Alternate Production

Develop a fully servo dual line spring machine with a stable output of 180 springs per minute, which can alternately produce springs of two different materials to meet the needs of new mattresses.

High-Response Line Frame with Inverter Control Solution

High response wire frame frequency converter control scheme, PLC plans the frequency analog quantity setting value, predicts and coordinates with dual wire machine head action, eliminating frequency converter response delay, and making the action smoother and more stable at high speed.

Small Chains as a Replacement, Efficient and Stable

Replacing traditional molding and bagging with small chains, the spring is pushed into non-woven fabric for packaging, which is efficient, stable, and reduces vibration caused by mechanical collisions.
