Description

Liquid material filling control device
Technical field
The utility model relates to a kind of liquid filling device that is applicable to the fields such as medicine, food, chemical industry, is specifically related to a kind ofly can realize the liquid filling and liquid material filling control device that fills by gravity alternately with pressure.
Background technology
The liquid quantitative filling equipment in current whole filling and package field, generally adopts the filling and two kinds of canning meanses that fill by gravity with pressure.So-called with pressure filling, pipeline is directly connected with filling head, material is directly delivered to filling head by charging pump, therefore with pressurely fillingly can ensure fast speed filling speed, but due to the fluctuation of feed pressure, particularly for the equipment of multiple filling heads, after closing at certain filling head, can cause line pressure fluctuation, cause the flow irregularities fluctuation of other filling heads, have a strong impact on the filling accuracy of equipment.What is called fills by gravity, material is first transported in hopper by pipeline, then hopper is connected with filling head by pipeline, filling pressure depends primarily on the density of material and the height of material liquid level in hopper when filling, for the equipment of multiple filling heads, after filling head is closed, the fluctuation of pressure producing can feed back in hopper, because the volume of hopper is enough large, the material level that fluctuation of pressure causes is fluctuateed compared with I to ignore, thereby hopper has served as the suction container of fluctuation of pressure, ensure the basicly stable of material pressure and flow, therefore fill by gravity and solved the shortcoming that filling fluctuation of pressure with pressure causes the bad control of filling accuracy, but the filling speed filling by gravity is low, and the general volume of hopper adopting is large, not easy cleaning, easily cause material to pollute.
Utility model content
The purpose of this utility model is to provide a kind of can realize the liquid filling and control setup alternately that fills by gravity with pressure, this filling control device combines filling speed with pressure soon and the precision that fills by gravity is held manageable advantage, improve filling speed, ensured again filling accuracy.
The utility model is a kind of liquid material filling control device, wherein: comprise filling head, feed pipe and accumulator; Inlet valve is housed in the middle of feed pipe, and feed pipe one end is connected with filling head, and the other end is inputted the filling material of needs, the circulation of inlet valve control material in feed pipe and blocking; Position between flange and inlet valve, feed pipe is provided with a branch road, and this branch road is connected by threaded line pipe with accumulator; Accumulator comprises air cavity and material Liang Ge chamber, chamber, and they are isolated by piston packing, and air cavity is connected with control cock by tracheae, and material chamber communicates with feed pipe; Control cock imports or blocks industrial instrument general mood or atmosphere.
A kind of liquid material filling control device as above, wherein: control cock comprises two pores: the first pore and the second pore, these two pores are communicated with respectively industrial instrument general mood or atmosphere; Control cock is blocked by the connected sum of controlling tracheae and the first pore and two pores of the second pore, control air cavity and industrial instrument general mood or atmosphere is connected and air cavity self is airtight.
The liquid material filling control device the utility model proposes, not only improve speed and the precision of pouring process, and cancelled hopper from structure, equipment operating flow process has been no longer included and clean this step of hopper, simplify filling process flow process, reduced material waste.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
Liquid quantitative filling equipment at present, in order to meet the double requirements of filling speed and filling accuracy, mostly adopt the filling pattern of double speed: first adopt large flow high-speed canning, before reaching the filling amount of requirement, filling amount closes large flow filling, be switched to low discharge filling, reach high-speed, high-precision requirement.Therefore, thinking of the present utility model is: in conjunction with the feature of aforesaid way, when filling apparatus is in the time that large flow is filling, adopt with pressure filling, to improve filling speed, in the time that low discharge is filling, convert to fill by gravity or with the similar voltage-stabilizing filling that fills by gravity, to ensure filling accuracy.
As shown in Figure 1, the liquid material filling control device that the utility model proposes comprises filling 1, feed pipe 6 and accumulator 3.Inlet valve 7 is housed in the middle of feed pipe 6, is connected by flange 5 with filling 1 and accumulator, be connected by threaded line pipe 4 with accumulator 3.The break-make of inlet valve 7 can be controlled the circulation of material in feed pipe 6 and block.Accumulator 3 comprises air cavity A and material two chambeies of chamber B, and they are by piston 2 seal isolation, and air cavity A is connected with control cock 9 by tracheae 8, and material chamber B is connected with feed pipe 6.Control cock 9 has P1 and two pores of P2, and these two pores can be communicated with industrial instrument general mood or atmosphere.Control cock 9 is blocked with the connected sum of P1 and two pores of P2 by controlling tracheae 8, can control air cavity A and industrial instrument general mood or atmosphere is connected and air cavity A self is airtight.Whether, when filling, the material direction of arrow as shown in Figure 1 flows, control to fill material in the packing material such as bucket, tank for filling 1.
First open inlet valve accumulator is filled, after accumulator is filled, opening filling head, to carry out large flow filling, in the time that filling amount reaches low discharge setting value, close inlet valve, the logical atmosphere of pore or the constant instrument general mood of malleation of accumulator, carry out low discharge filling, until filling complete.
Fig. 2 is the workflow diagram of the liquid material filling control device that proposes of the utility model.At first, close for filling 1.In step S1, control cock 9 controls air cavity A and atmosphere is communicated with, inlet valve 7 conductings, material with pressure enters in material chamber B by inlet valve 7, and promote the direction that piston 2 dwindles to air cavity A and move, material chamber B increases, and air cavity A dwindles, material is full of accumulator 3, and it is airtight that then control cock 9 is controlled air cavity A self.In step S2, to open for filling 1, the direction of material with pressure as shown in Fig. 1 arrow, flows in the packing materials such as bucket, tank, and at this moment pouring process is with pressure filling, and material is promoted by pressure, and flowing velocity is fast, can realize large flow Quick-filling, improves filling speed.In step S3, control system can be according to weight or liquid level etc., judges that whether filling large flow is complete, and the filling amount of large flow is generally the 95%-99% of whole filling amount.In step S4, inlet valve 7 cuts out, control cock 9 is controlled air cavity A and atmosphere or stable industrial instrument general mood conducting, material by gravity or/and stable pressure promote, by material chamber B, through filling 1, flow in the packing materials such as bucket, tank, material flow is slow, pouring process by with pressure filling converted to fill by gravity or with the similar voltage-stabilizing filling that fills by gravity so that ensure filling accuracy.In step S5 and S6, after pouring process, filling head is closed, and then control flow jumps to step S1, can carry out so again next time filling.
Above embodiment of the present utility model is explained in detail, above-mentioned embodiment is only optimum embodiment of the present utility model, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skill in the art, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
