Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, design feature of the present embodiment according to terrier storage cabinet, divides the material module of terrier storage cabinet,
Three phases are divided into, as shown in fig. 1, are followed successively by stage and material tail stage in material head stage, material.
According to the design feature of terrier storage cabinet, distribution is driven a vehicle after cloth, and certain slope, therefore terrier storage is presented in material in terrier storage cabinet
When cabinet discharging, tail band frequency should adjust accordingly, ensure the stability of quantity tube feed flow.
Currently, in the production process of general stalk, operative employee needs to combine knowhow that tail band frequency, discharging is manually set
When, tail band original frequency is adjusted to 50Hz, and with increasing for terrier storage cabinet discharging end offal, frequency is adjusted to 30-35Hz.But it produces
The preceding quantity tube pre- stone time is short, since the frequency values of artificial settings, change frequency time node are inaccurate in production process, storage
The variation of tail band frequency cannot cause quantity tube to occur being fed not in various degree from the output of motion tracking electronic scale flow in stalk cabinet
The phenomenon of foot, as shown in Fig. 2, flowed fluctuation is fairly obvious when material head stage and material tail stage, due to being fed instability of flow, meeting
Equipment frequent start-stop is caused, there are putty, cutout potential problems.
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 material head stage, material；
Step S140, when the tail band in terrier storage cabinet moves, the stage where the remaining ratio-dependent material that discharges；
Step S160 adjusts the frequency of tail band according to the stage where material using corresponding default rule.
The method of FREQUENCY CONTROL described above is according to the remaining discharging ratio of terrier storage cabinet by the material in terrier storage cabinet from terrier storage
