Pet Bottle Liquid Production Line Rinsing Filling Capping 3 In 1 Monoblock Machine

Automatic Carbonated Drinks PET Bottle Rinsing-Filling-Capping 3-in-1 Monoblock Machine

Working Procedure:

Bottles are fed from air conveyor into the filling machine monoblock via starwheel. Bottle clamp installed on the rotary wheel of the rinser will grip bottle mouth and make a 180º turn along a guide track to face the bottle mouth downward. In designated section of the rinser, rinsing water will jet out from special nozzles to flush bottle inside wall. After rinsing and dripping, bottles gripped by bottle clamp will make another 180º turn along a guide track to resume bottle neck facing up position. Clean bottles are discharged out of the rinser by a starwheel to feed the filler. After entering the filler, bottles are retained by bell cover at the mouth, which are actuated by elevating cylinder to raise them to engage with filling valves, and bell-cover is also lift up at the same time. Filling valves are opened by bottle presence signals. After finishing filling, valves are closed by valve closing mechanism to further stop venting to complete the filling process. Bottle carrier mechanism is lowered by a cam to disengage filled bottles with filling valves. Then bottles are transferred into the capper by a neck handling starwheel. Anti-rotation blades on capping heads will seize the bottle neck to prevent it from rotation and hold it in an upright position. The screw capping head will make revolving and rotating movement along with the machine to finish the complete capping process of cap picking, placing, twisting and disengaging under the control of a cam. A discharge starwheel discharges finished bottles onto discharge conveyor belt to be conveyed out of the filling monoblock.

Equipment Structure

1. Bottle infeed

l Bottle infeed by combination of air conveyor and infeed starwheel.
l Equipped with bottle jam protection device.

2. Rinser

l The rotary wheel is a fully stainless steel welded structure.
l The machine applies unique overturning bottle clamp, which is an innovation of our company. This bottle clamp grips bottle at neck position, avoiding bottle mouth thread contamination caused by rubber gripper block of a traditional bottle clamp. Made of SUS304 stainless steel, this bottle clamp is hygienic and durable.
l The high efficiency atomizing spay nozzle installed on bottle clamp is capable of cleaning any part of bottle inner wall, and also saves rinsing water.
l All sliding bushes of lifting device use Igus (Germany) anti-corrosion maintenance free bearing.
l The rinser is driven by driving system positioned inside machine frame via gear transmission.
l Transfer starwheel
l Made of stainless steel of superior quality.
l Equipped with bottle jam protection device.

3. Transfer Starwheel

The material is super-corrosion stainless steel ,the wheel has block bottle protect device.

4. Filler

l Rotary wheel fully made of stainless steel SUS 304.
l Isobaric filling method.
l Filling valves are made of SUS316L.
l Filling valves are reasonably structured with accurate filling.
l Bottles go up and down by pneumatic cylinders and cams, to process filling with contact to bottle-mouth.
l Level of cylinder is controlled with float-ball.
l Filler is driven through gears inside the machine frame.
l Link-wheels in rinser, filler and capper are transported in ringed support of bottle-neck.

5. Capper

Capper is the machine with highest precision, influence very much with the stability and reliability of the filling monoblock. Our capper features as follows:
l The equipment is designed with the support of experts from school of engineering and mechanical in Shanghai Jiao Tong University, and uses the technology of Arol from Italy, most advance technology in the world, developed with the experience of asepsis filling machine. For example, I) extruding wheel (main part to control the stability when sealing), uses the technology of Arol. Kinematical and kinetic design of the wheel by experts improves the stability and credibility of the equipment. II) Sealing faucet (main part to control the credibility of sealing), is improved by experts with the design of alnico. Besides the magnetic contortion variation device, there is variation dial which makes variation more easily. The benefit of this design is not only it can set the contortion, but also it makes contortion more precise and credible, and reduces inferior.
l Cap distributing chute is equipped with reverse cap stop and reverse cap pick-out mechanism.
l Cap distributing chute is equipped with a photocell switch to stop the capper when there is no cap inside the chute.
l The capper is equipped with inlet bottle detection switch.
l Centrifugal way of cap arranging is adopted to reduce damage of caps.
l A cap inspecting system is applied to control on-off of elevator.

6. Discharge Starwheel

l Nylon starwheel and conveyor belt work together to discharge bottles.
l Equipped with bottle jam protection device.

7. Discharge Conveyor

l Driving motor is frequency inverted to synchronize with the filling line to prevent bottles from falling.
l Discharge conveyor is equipped with photocell switch to slow down and stop filling line in case of fallen bottles.

8. Machine Frame

l The machine frame is a welded structure of high quality carbon steel with the surface anti-rust treated and coated. The machine frame is wrapped with stainless steel sheet.
l Driving system of the 3-in-1 Unit is positioned under the machine table. One main motor provides driving power via gear transmission.
l The gear transmission system is an interleaved arrangement of steel gears and nylon gears.
l The output shaft of the main motor is equipped overload protection to secure machine safety.

9. Electrical control system

The electrical cabinet is made of stainless steel. From bottle infeed to bottle discharge, a PLC controls the fully automatic operation of the 3-in-1 Unit.
