Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
As shown in figure 1, construction featuress of the present embodiment according to terrier storage cabinet, are divided to the material module of terrier storage cabinet,
Three phases are divided into, as shown in fig. 1, stage and material tail stage in stub bar stage, material is followed successively by.
According to the construction featuress of terrier storage cabinet, after distribution driving cloth, material is presented certain slope, therefore terrier storage in terrier storage cabinet
During cabinet discharging, tail band frequency should be adjusted accordingly, it is ensured that the stability of quantity tube feed flow.
At present, in the production process of general stalk, operative employee needs to be manually set tail band frequency with reference to knowhow, discharging
When, tail band original frequency is adjusted to 50Hz, and with increasing for terrier storage cabinet discharging end cabo, frequency is adjusted to 30-35Hz.But produce
The front quantity tube pre- stone time is short, because the frequency values that are manually set, change frequency time node are inaccurate in production process, storage
The change of tail band frequency in stalk cabinet can not cause quantity tube to occur feed in various degree not from the output of motion tracking electronic scale flow
The phenomenon of foot, as shown in Fig. 2 flowed fluctuation is fairly obvious when stub bar stage and material tail stage, due to feed instability of flow, meeting
Equipment frequent start-stop is caused, there is putty, cutout potential problem.
For this purpose, as shown in figure 3, the control method for frequency of an embodiment includes step S120 to step S160.
Step S120, according to the remaining discharging ratio of terrier storage cabinet by the material in terrier storage cabinet from the discharge end of terrier storage cabinet successively
It is divided into stage and material tail stage in stub bar stage, material；
Step S140, when the tail band in terrier storage cabinet is moved, according to the stage that remaining discharging ratio-dependent material is located；
Step S160, the frequency of tail band is adjusted according to the stage that material is located using correspondence default rule.
The method of the above FREQUENCY CONTROL is according to the remaining discharging ratio of terrier storage cabinet by the material in terrier storage cabinet from terrier storage
The discharge end of cabinet is in turn divided into stage and material tail stage in stub bar stage, material, in the frequency of different stage adjust automatically tail bands

Wherein, when determining module is according to remaining discharging ratio-dependent material stage in material, i.e., as shown in figure 1, current
Remaining discharging ratio m% be more than m2% and less than m1During %, the frequency that adjusting module is additionally operable to design tail band is predeterminated frequency
Value, is adjusted according to the state of the low level photocell of quantity tube to predeterminated frequency value.
In the present embodiment, predeterminated frequency value is theoretic frequency f1, it is possible to by the state of the low level photoelectricity in quantity tube
Adjustment predeterminated frequency value.Preferably, when photocell state be low light without material when, increase Δ f (Hz), Δ f at interval of second time t
Can be a fixed numerical value, specifically can carry out data according to practical application and determine selection.When the state of photocell is low
When light has material, tail band frequency need not change.When the state of photocell has for low light expects 2 seconds, then reduce at interval of second time t
Δf(Hz).When the state of photocell has material 2 seconds for middle light, then it is 0 to adjust tail band frequency.
It is appreciated that in cigarette machine, the equipment such as terrier storage cabinet and electronic scale, quantity tube is used cooperatively, and timing is managed
In be provided with low level photocell for detecting to material, be conventional application, the present embodiment is no longer illustrated.
Wherein, when determining module discharges ratio-dependent material when the tail stage is expected, i.e., as shown in figure 1, current according to residue
Remaining discharging ratio m% be less than m2During %, adjusting module be additionally operable to arrange tail band frequency deduct for default initial value it is pre-
If initial value and current residual discharge ratio product.
I.e. when material is when the tail stage is expected, frequency f=50-50*m%=50 (1-m%) of tail band.
It will be evident that by the adjustment to three above stage correspondence tail band frequency, the gradient can be avoided to shadow during discharging
Ring, make the output of the change of tail band frequency from motion tracking electronic scale flow, prevent electronic scale real-time traffic from fluctuating widely, it is fixed to make
Buret feed is stablized, and makes terrier storage cabinet discharging uniform flow.
