Abstract

The machine includes air compressor, sterile air filter, bench, clamping robot, pipe pump, steam valve, sterile filling chamber, lifting robot, by-pass valve, flow rate transmitter, feeding valve, filling valve cylinder, flow rate accumulating instrument and printer and composite cylinder, which is on the sterile filling chamber and consists of three cylinders in the same axis, three pistons and two layers of telescopic piston rods. The use of composite cylinder and sterile filling chamber makes the filling process bacteria-free. The machine has also the advantages of simple structure, steam disinfection and no chemical residue inside the filling bag and at the mouth of bottle.

Description

Sterile liquid filling machine

The present invention relates to the Canning Technique field, the sterile liquid filling machine of the packed liquid beverage of particularly a kind of suitable can flexible packaging.

The aseptic packaging of liquid is nearly two, the new process that grew up in 30 years, and sterile liquid filling machine is a key equipment of realizing this technology, how many liquid germ-free loadings is divided into aseptic Packaging and big packing two classes of aseptic pocket type by Packing Unit, at food, industry such as beverage and pharmacy need be packed at normal temperatures to various liquid or half-blank, so that long preservation, fresh-keeping and accumulating, the present employed overwhelming majority is an import equipment, exist the device structure complexity, the shortcoming that cost is high, and previously used packaging process is finished between an aseptic behaviour does, by manually with these filling liquids in plastics or iron ware, the inevitable like this secondary pollution problem that exists makes that product design is difficult to guarantee, the long preservation that is unfavorable for product, fresh-keeping and accumulating.

The purpose of this invention is to provide and a kind ofly can finish sterilization automatically, uncap, the sterile liquid filling machine of can and pass lid.

The present invention is achieved in that it comprises air compressor, aseptic air filter, bench board, can chamber clamping manipulator, tubing pump, cap relief valve, sterile filling chamber, elevating gear hand, bypass valve, flow transmitter, inlet valve, the filling valve cylinder, flow integrator and chopping machine are provided with a Composite cylinder in sterile filling unit room upper end, and Composite cylinder is made up of three pistons of three cylinders and two-layer telescoping piston rod on the same axis.

The present invention is owing to be provided with Composite cylinder and sterile filling chamber, therefore can guarantee in pouring process asepticly, and it is simple also to have a device structure, uses steam sterilization, in the Filling bag and bottle mouth position do not have the advantage of other chemical residue.

The present invention will be further described below in conjunction with accompanying drawing,

Fig. 1 is the structural representation of sterile liquid filling machine,

Fig. 2 is the structural representation of Composite cylinder,

Fig. 3 is the left view of Fig. 2,

As Fig. 1--shown in 3, this sterile liquid filling machine comprises air compressor 1, aseptic air filter 2, bench board 3, can chamber clamping manipulator 4, tubing pump 5, cap relief valve 6, sterile filling chamber 7, elevating gear hand 8, bypass valve 10, flow transmitter 11, inlet valve 12, filling valve cylinder 13, flow integrator 14 and chopping machine 15 are provided with a Composite cylinder 9 in sterile filling unit room 7 upper ends, Composite cylinder 9 is by three cylinder 16--18 on the same axis, auxiliary piston 20, can piston 21 and two-layer telescoping piston rod 22 are formed, Composite cylinder 9 can drive elevating gear hand 8 and finish and uncap, gland, can are chewed on 23, move down, make sterile bag turnover can chamber, chew by the bag that clamping cylinder 23 control can chamber clamping manipulators 4 fix sterile bag, cover cylinder 24 control lid-moving machine tool hands 25 at the backward shift of uncapping by moving; Before can, need to connect source of the gas earlier, power supply is also adjusted the interior pressure of each cylinder, steam is connected, the jigger lifting piston 20 of Composite cylinder 9 moves down, bag is chewed the lower end that moves on to can chamber 7, manually bag is chewed then to put into and is chewed card and enter the auto-filling state, and the jigger lifting piston 20 of Composite cylinder 9 moves down, bag is chewed the lower end that card moves on to can chamber 7, manually bag is chewed put into then and is chewed card; Enter automatic filling state, move on the jigger lifting piston 20 of Composite cylinder 9, the back that puts in place clamps cylinder 23 and drives can chamber clamping manipulator 4 and bag is chewed clamped, and opens cap relief valve 6 sterilizations and prolongs a period of time; Sterilizing time is to closing cap relief valve 6; Composite cylinder is opened pkt. flap then, uncaps to move after putting in place to cover cylinder 24 actions and will cover displacement by lid-moving machine tool hand 4, and can begins, and bypass valve 10 cuts out at this moment; Inlet valve 10 is opened simultaneously, flow instrument 14 work, and after the setting to be filled, bypass valve 10 is opened, and the lid that bag is chewed is retracted, and auxiliary piston 19 on the Composite cylinder 9 and jigger lifting piston 20 move down lid are covered; The lid back clamping manipulator 4 that puts in place is decontroled, Composite cylinder 9 with bag chew send after, manually install bag and chew.
