The invention relates to a roller-resistance winding inspection monitor, which is characterized by comprising an emitting unit, a voltage stabilizing unit, a error output inhibiting unit at the electrification moment, an emitting and receiving synchronous processing unit, a photoelectric signal receiving and amplifying unit, a signal inspecting and reshaping unit, an outputting unit, pulse generators and an output protecting loop; the photoelectric signal receiving and amplifying unit and the emitting unit are combined to form the main channel of an infrared beam monitoring obstacle through the emitting and receiving synchronous processing unit and one pulse generator; and the photoelectric signal receiving and amplifying unit and the signal inspecting and reshaping unit, the outputting unit and the error output inhibiting unit at the electrification moment, are successively and electrically connected through the other output end and are simultaneously connected in series with the output protecting loop between the signal inspecting and reshaping unit and the outputting unit. The roller-resistance winding inspection monitor has the advantages that the photoelectric detection principle is utilized; the low level is output and the machine halts in time so as to avoid the machine from damaging when the deformation and the fracture of a roller rubber belt or knitting fragments aredetected; and on the other hand, the loop can regulate the sensitivity according to the actual production requirement.
Description
technical field [0001] The invention relates to a detection circuit, in particular to an anti-roller web detector. Background technique [0002] On the computerized flat knitting machine commonly used in the knitting industry, in order to make the knitting continue, the fabric pulling is mainly completed by rollers. During normal operation, the fabric piece is sandwiched between two smooth rubber belts of the roller, and the rubber belt is clamped by the rotating roller to drive the fabric to move. However, in the fabric weaving process, there will inevitably be rubber belts that are prominently deformed or even broken. This deformed or broken belt drives the fabric debris to entangle, and the debris rolls more and more with the rotation of the roller belt. If the machine is not shut down in time to clean up, the entanglement may pull the knitted fabric, resulting in deformation of the knitted fabric, and more seriously, the fracture of the steel needles used for knitting, ...
