Operation and Manual 200BPH PLC 5 GALLON WATER FILLING MACHINE
Methods of AIR DISINFECTED
1. ClO2 suffocating method
Every cubic meter needs 1ml activated ClO2 disinfectant. Hang up a roomy tank with disinfectant on the wall over 1 meter to the ground per 20 cubic meters and replace the disinfectant every three days. The disinfection would be more effective if the disinfectant was replaced.
2. Formaldehyde suffocating method
The working will be fully disinfected by means of formaldehyde suffocating. However, due to the strong irritating smell of the formaldehyde, which causes discomfort, using for disinfection once a week. Mix Moderate formaldehyde liquor (10~15 ml per cubic meter space) with 0.5g permanganate in a plastic container. Position the mixture at the center and four corners of the room. A vial with 25% ammonia should be placed in the room in order to neutralize the smell.
Formaldehyde 255~380ml and permanganate 126~190g should be applicable in a standard feeding room.
3. Spraying hydrogen peroxide method
Put hydrogen peroxide, which is in the dilution rate of 1:50, into the sprayer and sprays it equably to the feeding room with the dosage of 200ml per 100 cubic meters.
4. ClO2 spraying method
Spray 500~800ppm (1:25~40) activated ClO2 disinfectant to the room. The spray is featured with tiny particle, high decentralization and excellent effect. The dosage is 1m ClO2 disinfectant every cubic meter.
Sanitation is significant in the pure water production, especially in the place where it is quite wet. Under wet condition, germ and mildew grow easily. Therefore, the water factory should disinfect the working area. Usually, there are the following methods of air disinfected in the water factory.

Slinging, Removal & installation
Try to sling the set of equipment with packing box, which must be slung from the bottom of the equipment based on the pedestal as jumping-off point. Place some cartons or wood block on the interface between the tightwire and the machine body to protect the surface from damage. The machine should be kept on balance and vertical level so as to avoid impacting to it.
1. Overall arrangement for the equipment.
The location of the machine should be good for operation and room using, where should had a space over 1 meter all around for convenient operation and maintenance. It is unnecessary to place fixed setup for the machine as the machine only gets little vibration when it runs. Adjust each up-and-down screw of its legs to steady the machine with horizontal ruler, and screw it. In order to wash the machine and drain off waste water easily, it is necessary to set up a tap water pipeline and a drain alongside of the machine.
2. Selection of pump and pipeline
It is recommended that the pure water filling part and the washing part provide with one or two pumps respectively while collocation of pumps.
As the water is filled by filling pump intermittently, it is recommended to install ball valve (DN25) to adjust filling pressure, and supply water circumfluence for decreasing the load of pump while water filling stops. If the flux of filling pump is over 1.5tons/h, the lift head is 20m; if the flux of washing pump is over 1ton/h, the lift head is 25m. Employing separate pump for water supply under other conditions, it should increase the flux and lift head of pump so as to prevent bottle washing from uncleanness.
It is recommended to choose pipeline DN25 if the length of pipeline is less than 5 meters, install and connect washing pipeline of germfree water (pure water) with pipeline DN20. If it is more than 5 meters or with overmany crankles, it should enlarge the track, otherwise, output would decrease and the bottle would be unclean. The selection of pump and pipeline had been configured according to the required design before leaving factory; they need not to be reinstalled when you use our machine.
Meanwhile,
Note: The captioned pump and pipeline should choose food grade products.
3. Installation of power supply circuit
Installation according to power supply configuration offered by the machine, it must be earthed reliably with the wire marked ground wire (PE or green-yellow colour) in the machine. (Caution: Don’t earth it to the pipeline of water and electricity)
Connect the power supply of electrical net to the terminal block of Air Electric Leakage Switch on the device distribution box with multi-leading wires. Select appropriate wire diameter according to the power of the device. It is recommended to employ power wire of RV 5×4.0mm2—500wire diameter for three phase AC 380V.
4. Gas path installation
Connect the exit of air compressor gas source with the entrance of oil-water separator on distribution box of filler, it is recommended to use the following parameters: volume capacity 0.1M3,Kilogram volume 0.17M3/min, Rated exhaust pressure 1MPa/Cm2 (Adjust the air compressor to 0.55-0.8Mpa, of which will start up on 0.5Mpa and stop on 0.8Mpa). Start up the air compressor, turn on the gas source switch and regulate the pressure adjusting valve above the air-water separator to over 0.55Mpa in case of the air pressure over 0.8Mpa. (Note: The machine would fail to run normally if the air pressure below this value, it needn’t to regulate again after the pressure adjusting valve has been regulated. Method of air pressure adjusted: put up the pressure adjusting valve of oil-water separator, and adjust air pressure by clockwise and counter-clockwise.) Use JIS K2213 input oil (ISO VG32 same level oil). The oil adding volume can not surpass 80% of the cup. Figure 0 means oil volume minimum and figure 9 means oil volume maximum. The figure aims at the point as arrowhead direction. (Adjust it to figure 4 commonly): It can’t be circumrotated from 9 to 0 while must be turned by direct hour hand.
Note: In order to make the pneumatic components of this machine work more steady during its using, the oil feeder of the oil-water separator must be filled moderate JIS K2213 input oil ( ISO VG32 same level oil).
Mechanism of the machine
Washing part: consisting of conveying structure, water tank, water washing pipeline, etc.
Conveying mechanism of washing
The mechanism uses the whole machine frame as basic prop up with conveying electromotor and drive bearing fixed on the supporter. The conveying motor carries the driving shaft, driven shaft and two pairs of nylon chain wheels and stainless steel chains on the shafts. And then the stainless steel chains convey the bottle seat which is fixed on it to transfer the bottle to be disinfected.
Water tank
The machine equips two tanks made by stainless steel plate. One is used for disinfectant solution, which is employed for disinfectant collection and circulating. The other one is water tanks, which are employed for water collection and circulating. There is no water tank for pure water which will be refluenced to the water tank. There is a water gauge for observing the height of disinfectant.
Water washing pipeline
The machine’s pipeline is conglutinated by special water pipe fittings with food grade products. Disinfectant, germfree water (pure water) washing, germfree water (pure water) filling and water filling pipeline are independent. Disinfectant is supplied by water tank while germfree water (pure water) is supplied by outer mechanism; germfree water (pure water) washing and filling are separated into two pipelines, on which install one electromagnetic valve respectively. Individual electromagnetic valve and pump turn off after finishing washing or filling.
Filling capping system part: consisting of filling, capping and bottle sending system.
1.Bottle pushing & filling system
The bottle pushing mechanism is constructed by the connection of bottle pushing cylinder and stainless steel bottle pushing bracket, its fixed pedestal builds in the machine’s framework. Water filling system consists of stainless steel water filling head, filling electromagnetic valve and filling head location adjusting plate.
2.Cap-aligning, cap-covered and capping system
The cap-aligning system consists of cap-aligning box, cap-aligning tray, cap-aligning electromotor and bottle cap slide track. The cap is slid into the cap-covered area from the cap-aligning slide track for waiting to be covered. When the full bottles pass the cap-covered area, the cap is covered on the bottle head depending on the contrary force from bottle carrying and cap-covered mechanism, being pushed into the capping area synchronously. Capping mechanism consists of capping tray, capping cylinder and adjustable capping supporter. It starts to cap while the conveying electromotor runs. (The whole capping mechanism can be regulated up and down according to the height of the bottle.)
Note: In order to make the machine more stable during its working, the bottle caps on the cap-aligning mechanism must be kept dry and can not be dripped for prevention of electric breakage, which makes the equipment unable to work.
Machine’s framework
Main supporter of the machine consists of stainless steel foursquare pipe with beautiful appearance and firm structure. Subsidiary supporter which is joined to the main supporter functions for separating the workaround and supporting.
Bottle out conveying system
Bottle out conveying system consists of bottle out supporter, bottle pushing cylinder and bottle conveying slide track. The disinfected and washed bottles will be overturned to the bottle conveying slide track by the bottle washing conveying mechanism. The bottle conveying cylinder runs and pushes bottles to the filling location, then conveys it to the cap-covered area and capping area by next disinfected and washed bottle, and be pushed out.
Electric system
The electric part consists of PLC controller, AC contactor, Time Relay and Air Switch.
Pneumatic system
The pneumatic part consists of Cylinder, Pneumatic electromagnetic valve and pneumatic control electric control box.
Adjustment and operation of the complete set
Adjustment of the equipment
The machine had been tested precisely and run for a long time before leaving the factory. However, consider that the bolt of the machine may become loosened during the slinging and transportation; it should be regulated carefully before operation.
Adjustment of bottle washing part
Turn on the power and open the Air Electric Leakage Switch, turn the “Option Switch” to “Manual” position on the operation panel, then press “startup” button to observe whether the running direction of bottle washing conveying electromotor is correct. Check if the orientated flake of the bottle washing holder is in the range of the bottle washing oriented inductive switch (Alongside of pure water washing position). (Method: When each oriented flake runs to the bottle washing orientated inductive switch, check whether the LED on the orientated inductive switch lights on or not. Lighting means the orientation is normal; if not, the orientated inductive switch should be adjusted to front or back.)
Put a bottle into the bottle entrance when the LED lights up. Turn the “Option Switch” to the “Manual” position and press the “Startup” to run the machine for several cycles. Check whether bottles can be overturned into the bottle pushing supporter normally when the conveying electromotor stops. If it fails, the orientated inductive switch should be adjusted to the left or the right till the bottle can be overturned into the bottle pushing bracket. Check whether the center of bottle head aims at each washing nozzle, otherwise, it needs to be adjusted till every washing nozzle aims at the center of bottle head. The bottle circumrotating effect is realized by adjusting the water ejecting angle.
Adjustment of filling part
Adjust the speed of bottle pushing cylinder (Adjust the throttle-valve of the cylinder to accelerate or decelerate the speed of the cylinder.). Make the bottle pushing device to push the bottles to the filling position in the set time. Place a bottle on the pushing supporter and press the red or blue testing button on the bottle pushing pneumatic electromagnetic valve, then have the pushing mechanism convey bottles to the position of water filling. The testing button is inside of the distribution box. Check whether the center of bottle head aims at each washing nozzle, otherwise, it needs to be adjusted till every washing nozzle aims at the center of bottle head. The filling flux is regulated by the time adding, time reducing and ball valve of the filling pipe.
Adjustment of cap-covered and capping
Check whether the cap-covered and capping mechanisms can cover cap and cap accurately. If fails to cover cap, it reveals that the cap-covered mechanism’s slide track is too high. Bottles dropping down or failing to be carried means the slide track is too low, which need to loosen the nut beside the cap-covered path and adjust the track of cap-covered. After adjusting the height of slide path, unfirm cap-covered reveals shortage of spring force and bottle falling reveals the excess of spring force. Adjust the spring nut to increase or decrease the spring force. Capping will be effected by the pressure of the capping cylinder and the height of bottle. Shortage of the capping cylinder pressure will result in unfirm capping. Bottle over-height will result in destruction of bottles. On contrary, bottles under-height will result in unfirm capping. In such condition, the height of capping tray adjustor and pressure of cylinder should be regulated accordingly
Adjustment of bottle filling with 3 gallons 、5 gallons: and 6 gallons
As the device have the function of exchange filling with both 3 gallons \5 gallons amd 6 gallons, bottle pushing supporter and bottle carrying slide track should be adjusted while filling bottles of different size.
1). Adjustment of bottle pushing supporter
When bottles are filled with 5 gallons, the oriented pole screw of the bottle pushing supporter is transferred to its first aperture position (upper aperture position). Adjust the oriented pole screw on the bottle pushing supporter till the bottle is pushed out horizontally, and then screw the nut. When bottles are filled with 3 gallons, the oriented pole screw is transferred to its second aperture position (centre aperture position). Adjust the oriented pole screw till the bottle is pushed out horizontally, and then screw the nut.
2). Adjustment of bottle out supporter
When bottles are filled with 5 gallons, loosen the nuts between the bottle out slide track and filling slide track supporter. Move downwards the bottle out slip track and the whole filling slip track to the supporter of bottle out part, and then fasten relevant nuts. When bottles are filled with 3 gallons, loosen the nuts between the bottle carrying slip path and filling slide track supporter. Move upwards the bottle out slip track and the whole filling slide track to the supporter of bottle out part, and then screw the relevant nuts.
3). Adjustment of capping
Adjust the position of capping cylinder backwards and forwards till the center of bottle head aims at the center of capping mechanism.
4). Adjustment of the filling time
Adjust the filling time adding switch, the filling time reducing switch and the filling restoration switch to achieving satisfactory effect of filling.
5)、5 gallon s convert to 6 gallons:(1)The head of filling should strike the lengthen screw;(2)Cap-ahigning slideway should be replace 6 gallons;(3)Capping head lengthen screw should be replace 6 gallons lengthen screw.
Preparation before starting up the device
It is unavoidable that the bolts and nuts will loosen during the transportation. So before testing the machine, tighten all the bolts and nuts with standard wrench; check whether all the shafts loosen or even block the machine and the electricity lines disrepair or drop. Then clean up the sundries inside the machine. Switch the power supply on and start up the machine to check whether the machine runs smoothly. Shut off the machine immediately in case that any abnormity occurs, which should not be restarted until the trouble-shooting of the machine.
(Caution: The Distribution Box and Switch Panel have to be free from water in case of malfunction and electric leakage).
Working principle and systemic instruction of the device
Working principle of the device
The device employs PLC program automatic control and the working process is as following:
1) Turn on the Air Electric Leakage Protection Switch and the Emergency switch. The power indicator on the control panel lights up, which indicate that power supply of the device, has been put through and PLC is electrified.
2) Set “Option switch” to the position of “Automatic”, press “Startup” pushbutton once so that the AC contactor of the control conveying electromotor is on, and the device proceeds to work. Press the empty bottle inspected inductive switch for empty bottle inspected when the empty bottle is cut in the empty bottle installed position (Release rinsing signal by the bottle inspected inductive switch on the bottle rinsing district of entrance.) Bottle rinsing conveying electromotor proceeds to run and carry empty bottles to each working station for disinfecting and washing through chains and bottle holder. (Rinsed bottles pass through four working stations: the first and the second working stations is rinsing with ClO2 solution for 25 respectively; the third working station is rinsing with water for 20 seconds; the fourth working station is for pure water washing for 10 seconds When the conveying electromotor runs with empty bottles, of which enter the oriented inductive zone with inductive slice on the chains, the oriented inductive switch releases a signal to stop the conveying electromotor. Meanwhile, the washing pump starts to carry out corresponding disinfectant procedures. (The washing time is set up and controlled by PLC program.) After the completion of bottle washing, the cleaned empty bottles are transferred by the bottle washing conveying mechanism and dropped down on the bottle pushing supporter, the bottle pushing cylinder runs and pushes empty bottles to the filling position, which have the head of bottle filling aimed at the headof bottle. As soon as the completion of pure water bottle washing, the bottle-filling pump starts filling. (The filling time can be adjusted according to the user’s requirement.) PLC released a signal for shutting up the electromagnetic valve and pause of water filling while water filling finished. After the completion of filling, the bottle is carried to the cap-aligning district by next bottle for cap-covered, then is conveyed to the capping district, capping cylinder drives capping mechanism to tighten the cap. Consequently, a washing and filling cycle is completed.
Note: It works only when bottles are inserted before starting up the bottle conveying motor. (The
bottle inspecting signals will be release only when two bottles be inserted simultaneously.)The
bottle, which is inserted in the working station for washing and disinfecting after the bottle washing conveying electromotor has run, will be not treated by the Microcomputer control system. The device will not proceed rinsing and filling. It would cause damage to the device if it keeps on running.
Systemic instruction of the device
1) The working mode of the device can be selected through the “Option switch”. If the “Option switch” is positioned to “Manual” status, the “working status indicator” remains dark, press pushbutton “Startup” to run the bottle washing conveying electromotor. There is no other work goes on until undo the pushbutton “Startup switch”. When the “Option switch” is positioned to “auto” status, pressing pushbutton “Startup switch” and “Working status” indicator keeps lighting up, which indicate that the device’s system can proceed washing and filling bottle normally.
2) If there is no cap entering into the slide track or cap-covered district for awaiting cap-covered after running the device, please press pushbutton “cap-aligning assistant” and the cap-aligning mechanism will keep on working. If need to pause working of the cap-aligning mechanism, please undo pushbutton “Cap-aligning assistant”.
3) Instruction of indicator
There are four indicators including “Power supply”, “Working status”, “Filling” and “Error” on the control panel.
* Power indicator: Turn on the Air Electric Leakage Protection Switch and the stop switch, the power indicator lights up
* Working status indicator: The indicator is blinking when it is positioned to “Manual” status. Press “Startup switch”, the indicator keeps lighting up while it is positioned to “Auto” status.
* Filling indicator: The indicator lights up as soon as water filling.
* Error indicator: The indicator is blinking in case of shortage of air source.
4) Filling time adjuster (consists of three red buttons built in the distribution box.): A. Filling time adding switch: the filling time is added 0.2seconds for each press; B. Filling time reducing switch: the filling time is subtracted 0.1 seconds for each press. Filling time recovering switch: Press A and B at the same time. The recovering time of the filling time is 15 seconds (set by the PLC).
In addiction: Adjust the ball valve at the exit of the filling pump to change the flux of water filling. Adjust the ball valve to decrease the pressure in case of excess hydraulic pressure of water filling. Satisfactory effect will be achieved by such-and-such repeating adjustment.
