Material roller 2 is driven by motor 3, and controller 4 is connected with the first range cells 5 and the 2nd range cells 6 respectively, and controls the setting speed of motor 3.
Preferably, controller 4 is that micro-chip, programmable logic controller and central processing unit etc. have the one in the module of data processing function.
Preferably, the first range cells 5 and the 2nd range cells 6 are the sensor that ultrasonic distance-measuring sensor or laser range sensor etc. can be used for range finding.
Fig. 2 is the method flow diagram adopting the unreeling machine control flexible materials in Fig. 1 to put volume; With reference to Fig. 2, described method comprises:
S1, material roller 2 export flexible materials 8, then transfer out by conveying roller 1;
S2, the first range cells 5 obtain the first distance between itself and flexible materials 8, and are forwarded to controller 4, the 2nd range cells 6 obtain itself and material roller 2 bottom between the 2nd distance, and be forwarded to described controller 4;
S3, controller 4 calculate according to the first Distance geometry the 2nd distance received and regulate the setting speed of motor 3, so that flexible materials 8 forms a flexible materials pendency section 7 between conveying roller 1 and material roller 2, and making flexible materials pendency section 7 and the first range cells 5 keep setpoint distance, this distance can be 20 ~ 50cm. The calculation formula of the setting speed of motor 3 is:
nMotor=nset��j
