Description
Technical field
The present invention relates to a kind of liquid filling devices suitable for fields such as medicine, food, chemical industry, and in particular to Yi Zhongke
To realize that liquid is with pressure filling and fills by gravity alternate liquid material filling control device.
Background technology
The liquid quantitative filling equipment in entire filling and package field at present is generally used with pressure filling and is filled by gravity two kinds
Canning means.So-called with pressure filling, pipeline is directly connected with filling head, and material is fed directly to filling head by charging pump,
Therefore it is with pressure it is filling can ensure quick filling speed, but due to the fluctuation of feed pressure, especially for multiple filling
For the equipment of head, when after some filling head is closed, pipeline pressure being caused to fluctuate, the flow for leading to other filling heads is random
The fluctuation of rule property, has seriously affected the filling accuracy of equipment.So-called to fill by gravity, material is first passed through in pipeline to hopper, so
Hopper is connect by pipeline with filling head afterwards, filling pressure depend primarily on material density and it is filling when hopper in material liquid level
Height, for the equipment of multiple filling heads, after filling head is closed, generated pressure oscillation can feed back to hopper
It is interior, since the volume of hopper is sufficiently large so that material position fluctuation is smaller caused by pressure oscillation to ignore, thus hopper acts as
The suction container of pressure oscillation ensure that the basicly stable of material pressure and flow, thus fill by gravity solve it is with pressure filling
Pressure oscillation leads to the shortcomings that filling accuracy bad control, but the filling speed to fill by gravity is low, and the general body of hopper used
Product is big, not easy cleaning, be easy to cause material pollution.

Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
Liquid quantitative filling equipment at present, in order to meet the double requirements of filling speed and filling accuracy, mostly using double
The filling pattern of speed：First using big flow high-speed canning, closing big flow is filling before filling amount reaches requirement filling amount, cuts
It is filling to change to small flow, reaches high speed, high-precision requirement.Therefore, thinking of the invention is：With reference to the spy of aforesaid way
Point when filling apparatus is when big flow is filling, using with pressure filling, to improve filling speed, when small flow is filling, is converted into
Fill by gravity or with the similar voltage-stabilizing filling that fills by gravity, to ensure filling accuracy.
As shown in Figure 1, liquid material filling control device proposed by the invention includes filling head 1, feed pipe 6 and storing
Cylinder 3.Equipped with inlet valve 7 among feed pipe 6, it is connect with filling head 1 and accumulator by flange 5, passes through screwed pipe with accumulator 3
4 connections.The break-make of inlet valve 7 with circulation of the control material in feed pipe 6 and can block.Accumulator 3 includes air cavity A and material chamber
Two chambers of B, they are sealed off by piston 2, and air cavity A is connected by tracheae 8 and control valve 9, and material chamber B is connect with feed pipe 6.
Control valve 9 has two stomatas of P1 and P2, the two stomatas can connect industrial instrument general mood or air.Control valve 9 passes through control
It the connection of two stomatas of tracheae 8 and P1 and P2 processed and blocks, air cavity A can be controlled to be connected with industrial instrument general mood or air
And air cavity A itself is closed.When filling, material arrow direction flowing as shown in Figure 1, filling head 1 is controlled whether to bucket, tank etc.
Fill material in packing material.
It first opens inlet valve to be filled accumulator, after accumulator is filled, opens filling head and carry out big flow filling
Dress when filling amount reaches small flow setting value, closes inlet valve, and the stomata of accumulator leads to air or the constant instrument of positive pressure
General mood, it is filling to carry out small flow, is finished until filling.
Fig. 2 is the work flow diagram of liquid material filling control device proposed by the invention.At first, filling head
1 is to close.In step sl, control valve 9 controls air cavity A and atmosphere, inlet valve 7 to be connected, material with pressure by into
Expect valve 7 into pan feeding chamber B, and piston 2 pushed to be moved to the direction that air cavity A reduces, material chamber B increases, air cavity A reduces, material by
Accumulator 3 is full of, and then control valve 9 controls air cavity A itself closed.In step s 2, filling head 1 is opened, material with pressure such as Fig. 1
Direction shown in arrow is flowed into the packing materials such as bucket, tank, and at this moment pouring process is with pressure filling, and material is pushed by pressure, flowing
Speed is fast, can realize big flow Quick-filling, improves filling speed.In step s3, control system can according to weight or
Person's liquid level etc. judges whether big flow is filling and finishes that the filling amount of big flow is usually the 95%-99% of entire filling amount.
In step S4, inlet valve 7 is closed, control valve 9 control air cavity A and the industrial instrument general mood of air or stabilization conducting, material by
The pressure of gravity or/and stabilization pushes, and by material chamber B, through filling head 1, flows into the packing materials such as bucket, tank, material flow is slow, fills
Dress process by it is with pressure it is filling be converted to fill by gravity or with the similar voltage-stabilizing filling that fills by gravity, to ensure filling essence
Degree.In step S5 and S6, after pouring process, filling head is closed, and then control flow jumps to step S1, so again
It can carry out next time filling.
