Adopt above-mentioned preferred scheme, by arranging laser thickness gauge, original artificial thickness measuring operation can be substituted completely, the take-up operation of whole welding can be accelerated, need not again to before abdicate like that the regular hour give artificial thickness measuring use, therefore the function of storage rack obtains again alternative further.
As preferred scheme, Thickness sensitivity value and its thickness setting value compare by above-mentioned control unit, and as there is the deviation of one-tenth-value thickness 1/10, control unit controls driver element and reduces rotating speed or shutdown.
Adopt above-mentioned preferred scheme; make when there is one-tenth-value thickness 1/10 deviation; control unit can by the mode reducing driver element rotating speed or make it shut down; time of abdicating allow manually enter adjustment welding thickness; and then when detecting; if thickness meets setting value, control unit can continue to control driver element and start, thus paying out machine can restart direction operation.
As preferred scheme, above-mentioned driver element is motor, and this control unit reduces or improve the rotating speed of driver element in the mode controlling electric machine frequency.
Adopt above-mentioned preferred scheme, the rotating speed of driver element can be controlled in a kind of comparatively preferred mode.
As preferred scheme, above-mentioned tension pick-up is arranged at outlet.
Adopt above-mentioned preferred scheme, detect when entering into roll at welding, namely detect time the conveying of welding terminates soon, such detection just can not be subject to the impact of the course of conveying of back, thus make can be more accurate to the tension detect of welding.
As preferred scheme, above-mentioned tension pick-up is installed on admission machine with wire-crossing wheel form.
Adopt above-mentioned preferred scheme, make welding directly by tension pick-up, the detection of welding can be carried out with the linear formula of mistake.
As preferred scheme, above-mentioned laser thickness gauge is installed between two wire-crossing wheels of point of incoming cables.
Adopt above-mentioned preferred scheme, the welding between two wire-crossing wheels is in the state of tension, and such laser thickness gauge can be more accurate to the detection of the thickness of welding, and detect in point of incoming cables, also can adjust in time when going wrong.
