Tobacco mixes metering and the display packing of silk in wire-storing cabinet
Technical field
The present invention relates to mix in the tobacco cutting production line wire-storing cabinet metering and the display packing of silk total amount.
Background technology
Mix silk in the tobacco cutting production line and be meant that leaf silk, stem, expansion thread, sheet and shreds and residual silk add the pipe tobacco that mixes behind the spices in mixing the silk cylinder.At present, mix silk finished product place at the tobacco cutting production line special-purpose belt conveyer scale generally is not installed, but to the leaf silk, stem, expansion thread, sheet and shreds and residual silk have special belt to claim to measure respectively, five kinds of pipe tobaccos mix to gather and are transported to wire-storing cabinet behind the perfuming and store, to leaf silk through overmulling silk cylinder, stem, expansion thread, sheet and shreds and residual silk etc. add the not metering of total pipe tobacco weight behind the spices, and the picture of the centralized control room of storage pipe tobacco shows it is the total pipe tobacco weight that adds behind the spices in the wire-storing cabinet, could guarantee aborning cigarette prop up in pipe tobacco weight accurately.But silk producing procedures is not identical network with the switch board of wire-storing cabinet operation at present, can not be delivered to wire-storing cabinet to data by network.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the tobacco that provides a kind of accurate metering to mix the silk gross weight mixes metering and the display packing of silk in wire-storing cabinet.
For achieving the above object, the present invention adopts following technical solution:
It is under the auto state that mixes the electric cabinet of silk control that this tobacco mixes metering and the display packing of silk in wire-storing cabinet, the alleged value accumulative total of five belt conveyer scales of metering leaf silk, stem, expansion thread, sheet and shreds and residual silk is added together as the pipe tobacco cumulative amount of simulating drum outlet with institute spiced weight again, calculate spices weight according to the volume cumulant and the spices densitometer of spices;
In the programmable controller that mixes the silk switch board, write control program, add an accumulator and pulse counter in the program, programmable controller to wire-storing cabinet sends pulse, send out a pulse for per 8 kilograms, accumulator multiply by the pipe tobacco cumulative total that pulse equivalency calculates current transmission according to the step-by-step counting that sends simultaneously, till the difference of the pipe tobacco accumulative total that sends and actual pipe tobacco accumulative total is less than 8 kilograms, inconsistent as if two data, then send pulse always; The programmable controller of wire-storing cabinet adds up the pulse of receiving, calculates the pipe tobacco gross weight that enters wire-storing cabinet according to identical pulse equivalency, and the picture that is applied to centralized control room shows and control.
The present invention can be in wire-storing cabinet the picture of the centralized control room of storage pipe tobacco show the total pipe tobacco weight that adds behind the spices, accurate measurement, worst error is 8 kilograms, has satisfied to show and the control requirement.
Description of drawings:
Accompanying drawing is a flow chart of the present invention.
The specific embodiment:
Embodiment
Accompanying drawing has provided flow chart of the present invention.
At first under the auto state that mixes the electric cabinet of silk control, the alleged value accumulative total of five belt conveyer scales of metering leaf silk, stem, expansion thread, sheet and shreds and residual silk is added together as the pipe tobacco cumulative amount of simulating drum outlet with institute spiced weight again, spices density temporarily is set at 0.98, calculates spices weight according to the volume cumulant of spices.
In the PLC (programmable controller) that mixes the silk switch board, write control program, add an accumulator and pulse counter in the program, send pulse to the PLC of wire-storing cabinet controller, send out a pulse for per 8 kilograms, accumulator multiply by the pipe tobacco cumulative total that pulse equivalency calculates current transmission according to the step-by-step counting that sends simultaneously, till the difference of pipe tobacco accumulative total that sends and actual pipe tobacco accumulative total is less than 8 kilograms, if two data are inconsistent, then send pulse, so worst error is 8 kilograms (satisfy and show and the control requirement) always.The PLC controller of wire-storing cabinet adds up the pulse of receiving, calculates the pipe tobacco gross weight that enters wire-storing cabinet according to identical pulse equivalency, and the picture that is applied to centralized control room shows and control.
