Description
Technical field
The utility model relates to the Production of Enamel Wires weight metering, particularly a kind of enameled wire weight metering system of multi-thread horizontal enameling machine
.
Background technology
In the Production of Enamel Wires enterprise change process in modern times, require to strengthen, wherein in this process of enameled wire japanning,, need carry out the analysis of manufacturing capability the order of classes or grades at school of certain employee for personnel's emolument in convenient certain order of classes or grades at school of pool to the enameled wire in-situ production management.The analysis of manufacturing capability is mainly reflected in two aspects: the one, and power consumption value in the order of classes or grades at school; The 2nd, enameled wire output weight in the order of classes or grades at school.The power consumption value can be measured by electric energy meter in the order of classes or grades at school; And there are two problems in enameled wire output weight: on the one hand, the inlet wire specific lobe of enamelling machine equipment is more, and a number scope is at the 24-60 head; Requirement is carried out weight metering to each take-up head; If realize on-line metering with the existing ripe weight instrument and equipment in market, have installation question because of its volume causes greatly, and cost be high.Simultaneously, answer the enterprise management informatization requirement, need the weight record of each take-up head of enamelling machine be got off, carry out output than analyzing, just have a problem of statistical measurement with power consumption value in the order of classes or grades at school.On the other hand; In the Production of Enamel Wires process; The take-up head broken string situation can occur unavoidably, and existing enamelling machine equipment baker internal mechanical structure is to adopt hot air circulating system basically, and the baker that it heats with traditional whole dependence electric energy specific energy is mutually saved power consumption more.The principle of work of hot air circulating system is: the organic solvent that baker burner hearth enameled wire top layer paint volatilizes in heating process; Carry out flameless burning through circulation passage in catalyst chamber; The heat of burning is delivered to burner hearth through circulation passage again and is replaced the electrical heating energy, thereby realizes energy-conservation.When the head that broken string occurs when enameled wire increased, the organic solvent capacity of burner hearth heated volatile reduced, and the heat that catalytic combustion discharges reduces, thereby correspondingly not enough energy demand occurred and compensate by electrical heating, had increased interior power consumption of unit interval thus.Fluctuation appears in temperature in the baker because the hysteresis of heat supplement can make simultaneously, and the fluctuation of temperature can have influence on the quality of enameled wire.Be the best energy-saving effect that reaches, and guarantee that quality of enamelled wire, one of the measure that need take are exactly to occur the pull-up again of the enameled wire of the head of broken string timely, reduce the generation of temperature fluctuation situation in the enameling machine oven as far as possible.So the solution above-mentioned two problems, so the utility model enameled wire weight metering system is proposed.
Summary of the invention
The purpose of the utility model is to solve above-mentioned two problems and a kind of metering that both can realize each take-up head take-up weight of enamelling machine admission machine is provided, and can in the Production of Enamel Wires process, in time detect the enameled wire weight metering system of take-up head take-state again.The utility model can judge whether that needs make warning according to take-state, reminds operating personnel.
The technical scheme of the utility model is: the enameled wire weight metering system of the utility model; Include direct supply, control module, tension pick-up, IO load module; Wherein direct supply is that control module, tension pick-up, IO load module provide electric energy; The input end of the IO load module of the signal of collection tension pick-up is connected with the signal output part of tension pick-up, and the output terminal of IO load module is connected with the signal input part of control module, and control module is connected with man-machine interface.
Above-mentioned IO load module also is provided with the input register of storage data.
Above-mentioned control module regularly reads the input register value in the IO load module.
Above-mentioned control module is connected with man-machine interface through the RS232 bus.
For receiving the touch-control order that man-machine interface is sent, also can enameled wire be measured the result and send into the two-way connection that man-machine interface shows between above-mentioned control module and the man-machine interface.
The mentioned strain sensor is installed on the guide wheel; Include rocking arm, support, microswitch; At the enameled wire of motion under the dragging of traction electric machine on guide wheel; an end of rocking arm is connected with guide wheel, and the other end of rocking arm is rack-mount, can produce switching signal in the microswitch, judge whether line on the guide wheel is in the state of switch shell fragment that breaks and is connected with rocking arm.
The enameled wire weight metering system of the utility model is owing to adopt the structure that includes control module, tension pick-up, IO load module, man-machine interface, and tension pick-up is installed on the guide wheel of preceding ground of enamelling machine portal frame case, detects whether enameled wire is in the broken string state on the guide wheel; If the enameled wire broken string, guide wheel loses tension force, tension pick-up output low level 0; On the contrary; If enameled wire is broken string not, tension force is arranged, tension pick-up output high level 1 on the guide wheel.At first, the output signal of tension pick-up is connected to the IO load module, and the tension pick-up state storage is to the inner input register of IO load module; Secondly, control module periodically reads the input register of IO load module by means of 485 buses, obtains the state of tension pick-up; Then, control module is according to the state of tension pick-up with the enameled wire property parameters that is provided with in advance, like the enameled wire line density etc., the enameled wire weight on a certain group of guide wheel carried out periodic cumulative measurement; At last, control module measures the result with enameled wire, is sent to man-machine interface through the RS232 interface and shows and store, and realizes enameled wire weight on-line metering function.Simultaneously, enameled wire weight metering system judges whether to make alerting signal according to the tension pick-up output state of gathering, and reminds the operative employee in time to repair the broken string state.The utility model can be according to the enamelling machine equipment of different inlet wire head numbers; Corresponding increase and decrease tension pick-up and IO load module; Promptly can mate the enamelling machine equipment of a different number, realize any number enameled wire weight metering, expansion flexibly arranged because system possesses.In addition because enameled wire line density ρ (unit: value g/m) is smaller, the result who adds up in the unit interval be gram (g) level other, so the utility model result of calculation is very accurate.While, the mode of connection was simple owing to tension pick-up is relatively simple for structure, and rat tail is few, thereby installs easily.The utility model be a kind of simple in structure, flexible extension, easy for installation, metering accurately, have the enameled wire weight metering system of extremely strong practicality and promotional value.
