22000BPH PET bottled water filling monoblock

1,  General Introduction

Air conveyor is connected directly with filling machine, transfer of the bottle in the whole process is bottle neck held method. Advantages of this method: (1) height of machine is not necessarily adjusted with flexible bottle change (if the diameter of the bottle does not differ a lot). Only bottle handle is necessarily changed in a short time even if the diameter differs a lot, which is easy for customers to use, fee and time of bottle change can be saved. (2) Secondary pollution of the bottle mouth can be averted.

The operational process of filling machine is as below: bottles separated by bottle – in screw are transferred to the rinsing machine through star wheel when bottles enter the 3 in 1 filling machine. Bottle gripper is installed on the rotary disk of rinsing machine, which catches and pivots the bottle 180°along with the rail, and it makes the bottle mouth downwards. In designated area, specialized nozzle will spray the inner space of the bottle, whilst, rinsing the outer wall of the bottle. After washing and draining, bottle will be pivoted 180° along with the rail, with the bottle mouth upwards. Bottles washed will be transferred to filling units by star wheel. Bottles are held by the bottle – neck supporting board and ascended and descended in the function of the elevator mechanism of the cam. The gravity filling principle is adopted that the filling level is reached when the liquid reaches the vent tube. The filled bottle will descend and leave the filling unit, and be conveyed to the capping unit by transition star – wheel. Bottles under the capper are fixed by anti – rotation knife (bottle neck) so as to ensure the bottle is up – right and prevent bottle rotation. Capper in the capping machine keeps revolution while rotation at the same time, movements of cap seizing, cap covering, cap screwing and cap releasing are all done in the function of cam mechanism. Finished product will be transferred to bottle – out conveyor from the capping unit, and conveyed out of the 3 in 1 filling machine.

The machine looks elegant and graceful with console mode windows.

2,  Main Characteristics

1)   Bottle – in Mechanism

a)   Air conveyor is connected with bottle – in wheel directly.

b)   Pneumatic control system of bottle block.

3)   Rinsing Machine

a)   Rotary disk is made of stainless steel (ANSI304).

b)   Overturning gripper is exclusively designed by Newamstar. Bottle neck is held by gripper and pollution to thread of bottle can be prevented. The gripper is made of stainless steel ANSI304, which is hygienic and durable.

c)   Efficient nozzle is adopted that water is sprayed in pre – set direction. Any part in the bottle can be rinsed thoroughly with less water consumption.

d)   Gripper uses maintenance – free bearings (corrosion resistant) of brand IGUS (Germany).

e)   Momentum of rinsing machine is provided by inner transmission system transmitted by gear.

4)   Transition Wheel

a)   Bottle neck held wheel is made of stainless steel.

5)   Filling Machine

a)   Rotating panel is made of stainless steel.

b)   Gravity filling principle.

c)   Filling valve is made of SS 316L.

d)   High precision, high speed filling valve, tolerance ≤±2mm.

e)   The ball tank is adopted, and liquid level in the tank is controlled by the floating ball.

f)   Bottle lifting is controlled by elevating cylinder, bottle neck is blocked to stabilize the bottle.

g)   Momentum of filling is driven by inner transmission system through gear.

6)   Capping Machine

a)   Magnetic constant torque capper, the running of capper is steady which can ensure the effect of capping, and defective rate is less than 0.2%.

b)   Reverse cap stopping and rejecting device is installed on cap falling track. At the same time photoelectric switch is equipped, the machine will be shut down once no cap is detected in the track.

c)   Bottle detector is equipped before the capping machine, which will transfer the signal to control cap lock cylinder in the connection of cap falling track and cap separating board. Therefore, no bottle no cap can be realized, with less cap loss.

d)   High efficiency centrifugal cap unscramble, which can ensure less cap abrasion.

e)   Cap detecting device is equipped in cap unscramble to control the start-up of cap elevator.

7)   Bottle – out Wheel

a)   Bottle bottom transmission method is adopted with a spiral descending curve of the pallet (under the bottle bottom). Height of machine and conveyor is not necessarily changed when the bottle shape changed.

8)   Bottle – out Conveyor

a)   Frequency inverter is used in transmission motor, which can ensure the synchronization with 3 in 1 filling machine and prevent bottle falling.

9)   Machine Frame

a)   The frame of the machine is made of superior mild steel, with rustproof coating treatment on the surface of the machine. Stainless steel (ANSI304) is covered on the frame.

b)   Stainless steel table with anti – pull technology is exclusively used, together with “O” type sealing ring. Leaking of bearing pedestal and supporting shaft can be minimized with this construction.

c)   Transmission system is right under the frame of 3 in 1 filling machine, driven by a main motor through gear.

d)   Transmission gear arrangement is crossed with steel gear and nylon gear

e)   Overloading protection device is equipped on the output shaft of the main motor.

10)  ontrol System

a)   The whole process from bottle – in to bottle – out of the 3 in 1 filling machine is controlled by PLC system.

b)   The operation can be done on the touch screen, capacity, count, incident type and spot can all be displayed on the screen. Incidence time and type etc. can be recorded automatically.

c)   Main electric parts are procured from world famous brand so as to ensure the excellent performance of the machine. PLC and frequency inverter are procured from MITSUBISHI (Japan), touch screen is procured from MITSUBISHI or Pro – face (Japan), photoelectric switch is procured from TURCK (Germany), proximity switch is procured from BANNER (USA).

d)   All parts of pneumatic system are procured from FESTO (Germany).
