Feed filar machine

Our unit feeds filar machine to what aluminous silk feeds inside ladle, operation face plate pursues as follows.

The machine that feed silk operates face plate

Start, suspend pushbutton control a contactor, stop to dominate return circuit, power transmission. (electric machinery has transducer drive, advocate loop adds up to brake to give transducer power transmission, do not get contactor control. )

Litre canal, fall provide pushbutton control a contactor, by fall tubal pushbutton contactor is sucked add up to air cylinder to get report, the canal wearing silk of the machine that feed silk falls to steel to include buccal department, release air cylinder to cut off the power by contactor of pushbutton rising a canal, the canal that wear silk rises.

Pressure below, raise pushbutton control a contactor, by press next pushbutton contactor to suck add up to electric machinery to age aluminous silk is pinned below wheel load, by raise pushbutton contactor to release electric machinery gear to raise loose aluminium silk.

Transfer switch chooses to feed a clue, electric machinery is turning, silk is fed inside past steel bag, transfer switch is chosen withdraw a line, electric machinery inverts, aluminous silk go back. Rotate potentiometer controls rate. On tally but the rice number that set feeds silk, to rice number stops automatically later.

The operation flow when feeding silk is: Press the pushbutton that start- - fall tubal pushbutton- - press next button- - the choice feeds a clue- - set rice number- - rotate potentiometer begins to feed silk. After feeding silk, press raise- - rise a canal- - stop. Perhaps press directly stop, raise automatically, rise a canal.

Once jockey reacts, in the process that feeding silk, can appear now and then stop a phenomenon, in the process that feeding silk that is to say, gear of abrupt electric machinery is raised, the canal that wear a line rises, control system cuts off the power, want to continue to feed silk to must be started afresh- - fall canal- - pressure below.

Because produce rhythm strain, and the segment that feeds silk is more important, appear this kind of circumstance delays production. Sent two electrician to check to do not have failure isolation dot, we are whole and electrical engineering the job that the class drops at hand, concentrated force volume goes handling this issue.

The surface sees a problem not complex, start namely, stop the contactor that pushbutton control gives whole system that to control loop power transmission to be able to appear now and then release.

Suspect at the beginning stop pushbutton to often close point contact bad, likelihood as shake appear disconnect phenomenon, change then new pushbutton. But breakdown still exists, check circuit next, also did not discover to empty is received and be broken inside control line. Measure contactor coil voltage next, contactor is sucked voltage is normal also after closing. Is it possible that be contactor bad? Does coil interior have disconnect is empty received? Change then new contactor. But the problem still was not solved.
