Example 1
An embodiment of the present application provides a dosing device, including:
a mixing chamber 6; and
a plurality of feeding modules;
wherein, the feed module includes weighing device 3, feed bin 4 and speed governing feeder 1, and feed bin 4 is connected and together weighed by weighing device 3 with speed governing feeder 1, and speed governing feeder 1 is used for throwing the material in feed bin 4 to mixing chamber 6, and weighing device 3 can measure the volume of losing material of feed bin 4 and speed governing feeder 1.
Wherein, weighing device 3 can be set up in frame 2, and a plurality of feed modules can set up a support body as frame 2 alone, also can use a frame 2 together as long as do not have the interference each other. The speed-adjustable feeder 1 can adopt a feeding device which can adjust the feeding speed, such as a screw feeder.
The mixing chamber 6 may be a separate storage chamber, or may be a stirring chamber with a stirring function equipped with the stirring mechanism 5.
In the production process of some medicines or foods, a plurality of materials are required to be mixed and metered according to the proportion. The materials are respectively stored in a plurality of storage devices, in the working process, the weightlessness of the materials (after the materials leave the speed-regulating feeder 1) can be calculated by the weighing device 3, the feeding speed of the screw rod is regulated through feedback, and the entering speed of the materials is also regulated according to the proportion when the materials enter the mixing chamber 6 from the speed-regulating feeder 1. Specific examples are given below:
A. the three materials B and C are finally metered and mixed in equal proportion of 10kg, 20kg and 30 kg. The material is fed back by the weigher 3, and the speed of the speed-regulating feeder 1 below A, B, C three materials is regulated, so that the instantaneous ratio of the speed of the material entering the mixing chamber 6 is 10:20:30, when the material reaches the target values of 10kg, 20kg and 30kg, the three feeding modules are stopped simultaneously.
In brief, by arranging a plurality of feeding modules and measuring the material loss amount, each feeding module can accurately determine the material amount actually provided, and the feeding speed of the speed-regulating feeder 1 can be controlled according to the material loss amount, so that each feeding module can stop feeding at the same time and the feeding proportion meets the target proportion. The specific batching method can refer to the specific method proposed in examples 2 to 4, so that the ratio between the actual feeding amounts when the three feeding modules are stopped is in accordance with the target ratio. In this way, the production process of subsequent products can be guaranteed, defective products are not generated due to the problem of material proportion, and because the instantaneous proportion is the same as the target proportion, materials provided by the feeding modules can be mixed more uniformly after entering the mixing chamber 6, so that the mixing time is reduced, the production efficiency is improved, the more uniform materials are mixed, and the product quality can be improved to a certain extent.
Example 2
Referring to fig. 2, an embodiment of the present application provides a batching method applied to the batching apparatus provided in embodiment 1, the method including:
s10, setting the batching time T and the batching target value M, and starting the feeding module to work and feed to the mixing chamber 6;
s20, determining the theoretical speed V of blanking of the feeding module as M/T according to the set batching time and the batching target value;
s30, calculating the material loss amount of each feeding module in real time and calculating the average speed of actual feeding;
s40, adjusting the feeding speed of the speed-adjusting feeder 1 of each feeding module according to the material loss amount of each feeding module so as to ensure that the actual material loss amount of each feeding module conforms to the theoretical material loss amount;
and S50, stopping the operation of each feeding module at the same time.
By applying the batching method, the batching equipment can effectively control the feeding amount of each feeding module, so that the proportion of the amount of the materials provided by each feeding module meets the target proportion when the feeding is stopped.
Taking a single feeding module as an example, in the steps of calculating the material loss amount of each feeding module in real time and calculating the average speed of actual feeding:
the initial amount of material is M0Dividing T into N sections, each section of time being T, and the material quantity at the end of the x-th section of time being MxLet the accumulated lost material amount in x period be delta MxSatisfy Δ Mx＝M0-Mx(ii) a The actual average feeding speed in the x period is VxSatisfy Vx＝△Mx/xt。
By dividing the time and determining the material loss amount and the average speed in each time period, the comparison with the theoretical speed can be finely performed so as to adjust the feeding speed of the speed-regulating feeder 1.
In the step of adjusting the feeding speed of the speed-regulating feeder of each feeding module according to the material loss amount of each feeding module so as to enable the actual material loss amount to accord with the theoretical material loss amount:
in the next period of time, the compensation speed is obtained by adjusting the feeding speed of the feeding module so as to compensate the deviation value of the actual material loss amount and the theoretical material loss amount;
let the compensation speed be Vx+1Satisfy Vx+1＝[V×(x+1)t-△Mx]/t。
By compensating the deviation value for the previous period of time every next period of time, the overall speed fluctuation can be reduced as much as possible, the compensated structure is more stable, and the amount of compensation is more accurate.
If at TN-1In the time of (3), the deviation amount between the actual material loss amount and the theoretical material loss amount does not exceed the threshold value, and then each feeding module performs feeding speed compensation in the Nth period of time, so that all the feeding modules complete feeding according to the target value at the same time.
By compensating the feeding speed during the last period of time, it is avoided that the accumulated error during the previous period of time is not compensated.
For example, A, B, C three materials need to be proportioned, 10kg, 20kg and 30kg are needed respectively, and the time for completing the whole proportioning needs 10 minutes, so that A, B, C three materials theoretically need to realize 1kg/min, 2kg/min and 3kg/min on the feeding speed. The feeding amount can be determined according to the rotating speed of the speed-regulating feeder 1, but the feeding amount can generate certain deviation when the speed-regulating feeder 1 keeps the same rotating speed, for example, after one minute, the actual material loss amount of A, B, C three materials is 1.1kg, 1.9kg and 3.2 kg. When the deviation of the material amount of each stage exceeds a certain amount (exceeds a threshold value), compensation is carried out, if 0.3kg is used, deviation compensation is carried out on the next stage, and if the deviation difference is not always exceeded in the process, system deviation compensation is carried out on the last stage, so that the material is fed at the same time finally. Of course, the threshold of the deviation amount may be set to 0.1kg, 0.2kg, 0.4kg, 0.5kg, etc. according to the production requirement, which are all examples of the threshold of the deviation, and the setting of the threshold is not limited to be within these ranges. Wherein by controlling the feed rate, the instantaneous velocity of the material entering the mixing chamber 6 at each time period is also proportioned according to the target ratio, so that the material is mixed more evenly.
Example 3
Referring to fig. 3, an embodiment of the present application provides a batching method applied to the batching apparatus provided in embodiment 1, the method including:
s100, setting the batching time T and the batching target value M, and starting the feeding module to work and feed to the mixing chamber 6;
s200, determining the theoretical speed V of blanking of a feeding module as M/T according to the set batching time and the batching target value;
s300, dividing T into N sections, wherein each section of time is T, and dividing T into normal feeding time TIs normalAnd compensating the feeding time tCompensation；
S400, calculating the compensation speed V in the compensation feeding timeCompensationAnd in each time t, respectively using theoretical speed V and compensation speed VCompensationFeeding;
and S500, stopping the work of each feeding module at the same time.
By applying the batching method, the batching equipment can effectively control the feeding amount of each feeding module, so that the proportion of the amount of the materials provided by each feeding module meets the target proportion when the feeding is stopped.
Compensation velocity V in calculating compensation feeding timeCompensationAnd in each time t, respectively using theoretical speed V and compensation speed VCompensationThe feeding step comprises:
let MIs normalIs tIs normalThe material loss after the internal normal feeding is finished meets the requirement of VCompensation＝(V×t-MIs normal)/tCompensation。MIs normalThe product can be obtained by weighing.
By dividing the time periods and further designing a part of time in each time period for compensation, the feeding amount in each time period can be ensured to meet the target requirement, so that the whole feeding amount meets the target requirement, and each feeding module can stop at the same time and realize equal proportion mixing of materials.
For example, A, B, C three materials need to be proportioned, 10kg, 20kg and 30kg are needed respectively, and the time for completing the whole proportioning needs 10 minutes, so that A, B, C three materials theoretically need to realize 1kg/min, 2kg/min and 3kg/min on the feeding speed. The feeding amount can be determined according to the rotating speed of the screw, but the feeding amount can generate certain deviation when the screw keeps the same rotating speed, for example, after 55 seconds, the actual material loss amount of A, B, C three materials is 0.8kg, 1.9kg and 2.9 kg. Therefore, the whole feeding time can be divided into 10 sections, namely 1 minute is compensated again, for example, 1 minute in the first stage, one section of collection quantity is started in the first 55 seconds, and the material compensation calculation is carried out in the last 5 seconds, namely, after the 1 minute is finished, the weight loss of the three feeding modules is respectively 1kg, 2kg and 3 kg. After 10 minutes, the feeding targets of 10kg, 20kg and 30kg are reached, the speed of the materials is kept stable basically in the feeding process, the instantaneous proportion of the materials entering the mixing chamber 6 is in accordance with the target proportion, and the metering targets are reached simultaneously, so that the actual proportion is ensured to be the same as the target proportion. In addition, the instantaneous proportion can be ensured to be consistent with the target proportion, so that the materials in the mixing chamber 6 can be mixed more uniformly.
Example 4
The embodiment of the application provides a batching method, which is applied to the batching equipment provided in the embodiment 1, wherein batching time T is divided into N sections, feeding is carried out at a normal speed in a part of time section, feeding is carried out at a compensation speed in a part of time section, and feeding is carried out at the compensation speed in the Nth time section;
wherein, the compensation speed is V when the feed is compensatedH，VHDetermined according to the dosing method provided in example 2 or the dosing method provided in example 3.
That is, a part of the time can be selected to directly feed according to the theoretical speed V, and then a part of the time can be selected to feed in a compensating manner according to the compensating speed, the specific determining manner of the compensating speed can be determined in the manner mentioned in embodiment 2 or 3, and the specific value can be different, which only refers to the compensating speed uniformly, and it is not required that all compensating times are compensated according to the same value.
By applying the batching method, the batching equipment can effectively control the feeding amount of each feeding module, so that the proportion of the amount of the materials provided by each feeding module meets the target proportion when the feeding is stopped.
Optionally, normal feeding is carried out in odd time periods, and compensation feeding is carried out in even time periods;
alternatively, normal feeding is performed during even periods and compensation feeding is performed during odd periods.
The time periods are divided and are respectively compensated by odd-numbered sections or even-numbered sections, so that the feeding amount of the speed-regulating feeder 1 can be timely regulated, and when a plurality of feeding modules work, the feeding modules can be simultaneously stopped and the feeding proportion can be ensured to meet the target proportion.
It will be understood, of course, that the particular compensation time period may be determined in accordance with production conditions, and that the odd and even time periods are merely examples, which primarily indicate that compensation may be performed within a certain time period to ultimately achieve a ratio of material provided to meet a target ratio when the feeding modules are stopped simultaneously.
Furthermore, the selection of the respective compensation time period may be different for each feeding module and the manner of determining the compensation speed may also be different, as long as it is finally achieved that after compensation the instantaneous speed of the material supplied by the respective feeding module at the moment of entry into the mixing chamber 6 is proportioned to the target proportion, which also corresponds to the actual proportion of the material when the supply is finally stopped. That is, taking the parameters of the above example as an example, when A, B and C are finally mixed in a metered and equal ratio of 10kg, 20kg and 30kg, the target ratio is 10:20:30, and when entering the mixing chamber 6 can be realized according to the method, the instantaneous speed of each material is also proportional and in a ratio of 10:20:30, and then the ratio of the materials actually entering the mixing chamber 6 is also 10:20:30, which is the same as the target ratio.
In summary, the batching device of the present application can feed the mixing chamber 6 through the feeding module, and the material loss amount is used as the measuring basis, so that the actual feeding amount is accurate, and the measuring distortion of the feeding amount caused by the material residue on the speed-adjusting feeder 1 is avoided. On the basis of guaranteeing the accuracy of the feeding amount, the corresponding batching method is further combined, so that the instantaneous speed of the materials provided by each feeding module when the materials enter the mixing chamber 6 is proportional and is consistent with the target proportion, and finally, when the machine is stopped simultaneously, the actual proportion of the amount of the provided materials is the same as the target proportion. The quality of the product in the subsequent production is not influenced by the larger deviation between the proportion of the ingredients and the target proportion.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
