Filling sealing machine is a three-block that embraces rinser, rotating pouring and sealing units which have common drive. The assemblage of machine includes pneumatic conveyor section, electricity box, force-feed lubrication system. Bottle feed to pouring sealing machine is carried out with help of pneumatic conveyor. The machine includes two-meter conveyor section to which the conveyor of customer is mated. Supplied bottles are transported to rinser.
Rinser
Rinsing process at this machine appears to be momentary washing of inner surface of bottles after blowing-out using substance for rinsing (clean water) in order to remove dust that is neutral to accumulation of electrostatic pressure and easy-washable impurities represented by macroparticles that have no stable mechanic linking with bottle surface.
Operating principle of rinser
With aid of pneumatic conveyor the bottles are passed to tourniquet. Feeding star of tourniquet takes bottles at its mouth with teeth and passes them to grasp that takes the bottle at its mouth and moving on master cam it turns the bottle and passes its mouth to valve muzzle. Clean water is used for rinsing of containers, after washing this water is flushed to drainage system. The minimal pressure at input must be Pmin=1.5 atm. Recirculation system can be established upon request of customer. Bottle grasp consists of frame and moving element that moves by the action of spring. Set screw is established at moving element of grasp, it opens the delivery valve of flushing fluid only when a bottle is present. Upon absence of bottles the valve is in closed position. Such systems give a possibility to spare water. Passing one circle on rinsing wheel the grasps turn bottles to initial position (mouths upwards) and pass them to outloading star that transports bottles to input star of pouring unit.
Pouringunit
Food products are filled in bottles upon isobaric scheme that corresponds to the following principle: filling of bottles is carried out at constant pressure that is equal to pressure of gas in overliquid space of machine reservoir. Inflow of drink into the bottle is conducted by natural flow upon constant flow speed. The isobaric scheme of machine is fulfilled at single-channel system, meaning that reservoir for liquid is used simultaneously as gas channel of bottle filling.
Operating principle of pouring unit
Input star put the bottles at grasps of bottle mouths of lifting cylinders of pouring wheel that lift bottles vertically upwards under centering device of pourers. Upon lifting of bottles to extreme upper position their encapsulation with pourer through consolidator of centering cup is achieved. Pneumatic cylinder puts pouring patrons in position that corresponds to opening of gas valve. Gas mixture from overliquid space of reservoir through gas tube is forwarded to bottle. After equating of pressure in bottle and overliquid space of reservoir the valve of pourer is opened automatically by spring and the drink flows into bottle through circular clearance between bottle mouth and cone of gas tube. From the moment of opening of gas valve the control of presence of liquid in bottle is carried out in some time using indicator of bottle break. It is necessary in order to avoid the loss of product and gas pressure in reservoir upon break of non-standard bottles under pourer during equating of pressure. If a bottle is broken, pneumatic cylinder stops gas supply. Due to cone ring on gas tube the drink is forwarded down the bottle wall in thin jet that enables perfect filling of bottle and removes foaming. During filling of bottle the mixture of air and carbon dioxide is pushed out though gas tube into overliquid space of reservoir. When level of drink in bottle rises up to opening at the end of gas tube, the filling stops. Valve of gas supply closes, gas pressure relieve from bottle into atmosphere takes place. By action of master cam the bottles are moved down, the containers are taken from centering device, they are removed from pouring wheel using feeding star and are passed to sealing wheel. After output of bottle from pourer the blowing-down of gas tube is carried out. It is conducted by short-term opening of gas valve upon signal of controller. Upon absence of polyethyleneterephthalate bottle at lifting cylinder the gas and liquid valves will be closed because the control of bottle presence is executed by indicator.
Sealing unit
In sealing aggregate of machine the sealing of bottles is executed by plastic screw cap
Operating principle of sealing unit
Upon request of customer the bunker of cap feed can be established (fig. 1). The feed screw apparatus of cap consists of orienting device that receives caps from machine of cap feed and orients them from bed for supply to tourniquet star. Sealing head is equipped with magnetic coupling with help of which you can change the size of turning moment of head. The rotary moment is transmitted to sealing aggregate from central drive through drive gear. The machine has lubrication system, its duration and frequency is regulated from operator panel. Controller manages all processes carried out by this machine.
Advantage of machine:
- In case of malfunction the pourer is removed completely without whole disassembling of apparatus, it enables to spare time and labor. Repair and installation is executed out of machine (workshop);
- Machine structure provides minimal time between pouring and sealing, the losses of gas keep to minimum.
- Utilization of up-to-date ultra-sound control system of liquid level enables to define fast and accurately the level of bottle filling. Such system contributes to high efficiency.
- Water saving due to constructive peculiarities of parts of grasps of rinsing unit.
Pouring technology
Isobaric filling of liquids containing carbon dioxide is executed only upon level. A single-staged system of filling device is generally used for it.
Operating principle of single-staged filling device of machine
Filling product and gas are kept in general annular space. In order to create backpressure in bottle the gas is forwarded from annular space and during filling it is output from another jet into annular reservoir.
Saturator is an equipment used for saturation of water by gas CO2 at pouring lines of carbonated water, drinks and other liquids. In order to produce carbonated soft drink a mixer-saturator is used, its purpose is mixing of cooled clean water with coupage and saturation of drink by CO2. While filling of non-carbonated water the compressed air is used instead of carbon dioxide in order to create pressure in overliquid space. The liquid level in reservoir is controlled and regulated by liquid level gage.
Operating principle of liquid level gage of type VEGAFLEX 61 made in Germany
High-frequency microwave pulses are forwarded along the rod. Reaching the surface of product microwave pulses are reflected from it. On the basis of the time of pulse passing in-built electronics calculates the distance. The pressure in reservoir is regulated automatically. In case of breakage the system relieves pressure, the container is equipped with mechanical pressure-relief valve. The ultimate pressure is 6 atm.
You should have at disposal the following objects for changeover of machine for another frame size:
- level tube, amount 48 items (according to number of filling heads)
- output star assembled;
- shoe of output star.
