The invention provides a
bobbin insertion system of an automatic
bobbin winder and a
bobbin insertion method. The bobbin
insertion system of the automatic bobbin winder comprises a
control system, a bobbin
yarn release device, a fixed hopper, a movable hopper, a tray channel, trays, a first sensor and a second sensor, wherein the first sensor is used for judging whether each tray arrives at a bobbin insertion
station or not, the second sensor is used for judging whether bobbin
yarn exists on each tray or not, and the first sensor and the second sensor are connected with the
control system. The bobbin insertion
system of the automatic bobbin winder is characterized by further comprising a third sensor and a fourth sensor, wherein the third sensor is used for judging whether each tray is going to arrive at the bobbin insertion
station or not, the fourth sensor is used for judging whether the bobbin
yarn exists on each tray which is going to arrive at the bobbin insertion
station, and the third sensor and the fourth sensor are connected with the
control system. The bobbin insertion system of the automatic bobbin winder is simple and compact in structure, and the bobbin insertion efficiency can be improved. When the situation that one empty tray is going to arrive at the bobbin insertion station is detected, bobbin insertion of the previous empty tray is finished, the tray is released, then the control system enables the movable hopper to be closed immediately, and the bobbin yarn drops to the bottom of the movable hopper from the bobbin yarn release device arranged above the movable hopper and waits for the corresponding empty tray. The bobbin
insertion time sequence is reasonable, the bobbin yarn drop time can be shortened, and the bobbin insertion efficiency is high.
