Capping Mechanism & Torque Control Principle

The capping head utilizes a gripping mechanism. As the cap is placed onto the jar mouth, the servo-driven capping head descends and rotates at a controlled speed. A built-in torque sensor provides real-time feedback to the PLC: when the preset torque value (1–10 Nm) is reached, the servo motor instantly stops and releases the cap. This closed-loop control ensures every cap is tightened with ±0.2 Nm consistency, eliminating human error and preventing under-tightening (leakage) or over-tightening (jar/chip damage).

Cap Pre-alignment & Positioning System:

Before capping, the glass jar is precisely positioned by a star wheel or guide rail to ensure the cap is perfectly aligned with the bottle mouth. For non-circular jar shapes or special cap designs, an optional visual positioning system can be integrated to ensure accurate cap placement before the final torque is applied.

Anti-Misalignment & Rejection System:

The machine is equipped with photoelectric sensors to detect missing caps, tilted caps, or cross-threaded caps. Any abnormal condition triggers an automatic rejection mechanism, preventing defective products from reaching the downstream labeling or packaging stages and reducing manual inspection costs.
