The storing machine used before and after the utility model pinion and-rack storing machine can be used as, and its technological action is following:
1. preceding storage cloth machine
1.1 be positioned at after the splicer, before the immersion liquid groove;
1.2 alighting gear rests on extreme lower position at ordinary times;
1.3 rise and fall are initiatively, descending speed receives Tension Control, rises at the uniform velocity;
1.4 the counterweight total weight equals the balladeur train total mass;
1.5 adopt worm decelerating machine and torque limiter with self-locking characteristics;
1.6 storage cloth motor adopts servomotor, response time is the MS level, closed loop control, the startup of motor and stop to be the acceleration and deceleration process that acceleration and deceleration can be set, so start and stop steadily;
1.7 find uncoiling place cloth residue not for a long time, press " storing " button, storage cloth electric motor starting, alighting gear steadily rises, and steadily stops when arriving the top limit switch;
1.8 during uncoiling emptying, press " lock cloth " button, the pneumatic brake cloth device of storing machine entrance is clamped cloth before being contained in, so that carry out the joint operation.No matter alighting gear is rising or resting on the top at this moment, servomotor oppositely starts, and balladeur train is descending, and speed receives Tension Control, and storage cloth machine entrance is provided with the tension force measuring roll, and tension pick-up is installed;
