Background
At present, the problem of low success rate of yarn-end-finding is generally existed in the process of yarn-end-finding by a cheese suction nozzle of an automatic winder during yarn-end-finding breakage, especially in some special yarns, the repeated yarn-suction can damage a cheese yarn layer, and the production efficiency and the yarn quality of the whole machine are seriously influenced.
In Chinese patent literature, the invention patent with the name of a structurally optimized cheese adsorption auxiliary system and publication number CN104555602A discloses a structurally optimized cheese adsorption auxiliary system, wherein one end of a driven push rod is tightly pressed against a cam curved surface, the other end of the driven push rod is fixedly provided with a cheese suction nozzle positioning sensor, the driven push rod can slide along the length direction of the driven push rod to enable the cheese suction nozzle positioning sensor to be close to or far away from the cheese suction nozzle, a driving device drives the cheese suction nozzle to swing, a nozzle opening of the cheese suction nozzle is opposite to the surface of a yarn drum, negative pressure is arranged in the cheese suction nozzle, a sawtooth bent plate with a sawtooth structure on the surface extends from the opening of the nozzle opening of the cheese suction nozzle to the inside of the cheese suction nozzle for a set distance, and the sawtooth bent plate and the inner side wall of the cheese suction nozzle form an included angle.
The technical scheme improves the structure of the cone yarn suction nozzle, and the success rate of the cone yarn suction nozzle is improved; but the scheme needs to ensure that the air flow in the cheese suction nozzle is large enough, and the energy consumption is increased.
Disclosure of Invention
In order to solve the technical problem, the invention provides a method for realizing the inching yarn suction of a cheese suction nozzle, and aims to effectively improve the one-time head-finding success rate of the cheese suction nozzle, so that the one-time yarn suction success rate of the cheese suction nozzle is improved.
The technical scheme of the invention is as follows:
a method for realizing the point-action yarn suction of a cheese suction nozzle is characterized in that the cheese suction nozzle is driven by a stepping motor, a zero sensor is arranged at the ascending terminal position of the cheese suction nozzle, and a control system is in signal connection with the stepping motor; when the cheese suction nozzle moves upwards to the zero position sensor, the cheese suction nozzle starts to suck yarns; the control system provides a delayed running signal for the stepping motor; the locating point of the zero sensor is in limiting, the stepping motor enters an out-of-step state and outputs intermittent action, the bobbin yarn suction nozzle intermittently shakes, and the bobbin yarn suction nozzle is matched with negative pressure air of the bobbin yarn suction nozzle to realize point-action type yarn suction.
Compared with the prior art, the scheme utilizes the step-out characteristic of the stepping motor, can output intermittent inching actions, can realize the inching action of the cheese suction nozzle by matching with the negative pressure fan of the cheese suction nozzle, and greatly improves the one-time yarn suction success rate of the cheese suction nozzle.
Furthermore, the delayed running signal duration is set according to requirements, and the control system starts timing when the bobbin yarn suction nozzle upwards triggers the zero sensor. In the technical improvement, the out-of-step time of the stepping motor is designed, a control system starts to time when a bobbin yarn suction nozzle triggers a zero-position sensor, so that the stepping motor enters an out-of-step state of about 1S, and therefore intermittent action is output; the specific length of the step loss depends on the process requirements.
Further, the zero position sensor is arranged below the grooved drum.
The technical scheme has the beneficial effects that the one-time head-finding success rate of the cheese suction nozzle is effectively improved, so that the one-time yarn suction success rate of the cheese suction nozzle is improved.
