Description

Liquid pouring device in automatic sealing machine for liquid goods

The present invention relates to a liquid injecting device of the automatic juice packing machine, in detail, to straighten the liquid inlet vertically to open and close correctly without unnecessary blockage or opening so that the juice is correctly injected, easy to clean and maintain In addition, by suppressing the use of injection pumps and solenoid valves with high failure rate, the service life is greatly increased, and the failure rate and cost are greatly reduced.

In general, the automatic juice packing machine injects a certain amount of various liquids or juices such as herbal medicine, soy sauce, juice, sake, liquor, bottled water into a bag made of synthetic resin or aluminum paper (usually a retort pouch that can be placed on the bottom). Automatic packaging and discharging machine.

Figure 1 shows a conventional juice injection device (2) used in such a juice automatic packaging machine, looking at its structure is connected to the injection pump (8) for forcibly injecting juice into the discharge pipe (6) of the juice storage container (4) The solenoid valve 10 which opens and closes a flow path to the lower part of the injection pump 8 is connected, and the injection pipe 14 which injects the appropriate amount of liquid in the bag 12 to the lower part of the solenoid valve 10 is carried out. Connecting the cleaning pipe 18 having the hose 16 to the side of the discharge pipe 6 and connecting the inlet portion of the injection pump 8 and the outlet portion of the solenoid valve 10 to the elbow 20. ) Is connected to the juice injection device 2 is configured.

Due to the structure using the injection pump 8, the solenoid 10, and the elbows 20 and 22, the juice injection device 2 is not straight in the flow path (flow path) through which the juice passes, and is bent in several stages. This is not only because the configuration is complicated, but also the discharge resistance is increased, there is a problem that the smooth discharge of the juice is not made, the higher the viscosity (viscosity) of the juice is increased such discharge resistance.

That is, when cleaning, the straight section of the flow path can be smoothly cleaned with the help of a cleaning tool, for example, a long cleaning brush, but cleans the inner wall of the non-linear flow path bent under the elbow 20. In order to do this, a professional (skilled person) has to disassemble and clean the non-linear flow path part, and then reassemble it.

If the flow path cleaning process is cumbersome and neglects to clean the flow path, the remaining liquid in the flow path cools or hardens, leading to failure of the injection pump 8 or damage to the motor mounted on the injection pump 8 due to overload. If a small amount of juice leaks out as the shaft of the injection pump 8 leaks, the liquid is not only blown around the liquid injection device but also the flying liquid is buried in the impeller 8a, which is an air cooling device of the pump motor. Even when cured, there is a problem that the pump motor is overheated, so the life of the injection pump 8 is very short, about 3 months.

In addition, the packaging liquid is a high temperature treatment for sterilization or processing and has a slight viscosity, so the rubber packing of the soft material used in the injection pump 8, etc. causes a change in heat and hardens, causing cracks, which shortens the lifespan. The service life of the component is very short, and viscous liquids easily flow into the gap between the operation part, so that the opening and closing load is increased, so that the operation is not desired.

In addition, in the case of the solenoid valve 10 including the solenoid, the silicone hose, and the opening / closing mechanism, when the silicone hose is pressurized while the opening / closing mechanism moves forward by the pressing force of the solenoid, the flow path of the solenoid valve 10 is closed, and conversely, the pressing force of the solenoid is released. If the silicone hose that was pressurized while the opening / closing mechanism is retracted is restored to its original state, the flow path of the solenoid valve 10 is opened. When the dregs or foreign matter is caught in the opening / closing part of the silicone hose, There is a problem that the liquid does not flow completely because the opening and closing is not made, even if the valve 10 is opened, it does not flow properly.

In particular, when the foreign matter such as grape seed is caught in the opening and closing portion of the silicone hose, the above phenomenon occurs, in this case there is a problem that the expert must disassemble the parts to clean or repair (A / S) .

Therefore, an object of the present invention is to make it easy to clean, repair and manufacture by vertically straightening the flow path of the juice injection device through which the juice passes.

In addition, a reliable ball-valve is opened and closed by the forward and reverse rotation of the reduction motor in the middle of the flow path of the juice injection device, so that the juice injection flow path can be opened and closed. To achieve this.

In addition, it is intended to achieve a quantitative juice injection without the use of an injection pump forcibly injecting a liquid by installing a liquid quantitative injection device in the upper portion of the flow path of the straightened liquid injection device.

In order to achieve the above object, the cleaning elbow, the ball-valve and the juice injection pipe are connected to the juice discharge pipe of the juice storage container in order so that the juice injection passage is vertically aligned to clean and repair the juice injection device. It is easy to manufacture, fixing the connecting plate and the support plate between or around the cleaning elbow and the ball-valve, fixing the reduction motor which can be rotated forward and reverse on one side of the support plate, and rotating shaft and ball of the reduction motor. The opening and closing part of the valve is connected to the coupler to transmit the rotational force of the reduction motor to the ball-valve, and to install a working rod projecting in the direction perpendicular to the coupler on one side of the coupler to rotate along the coupler, the right side of the support plate and the support plate Install the bending support plate on the lower side of the motor, and then install the limit switches to set the stop section of the reduction motor, and operate the coupler between the limit switches. The limit switch is turned off by the pressing force of the rotating rod, and when the limit switch is turned off, the deceleration motor is stopped so that the ball-valve is opened or closed by 90 ° reciprocating rotation of the reduction motor. In addition, the branch of the cleaning elbow is connected to the ball-valve having a handle and the discharge hose so that the cleaned rinsed water can be naturally discharged.

In addition, the volume of the main tank in the bottom of the main tank, such as the 'liquid metering device of the automatic juice packing machine' registered in the Patent No. 226345, which is much smaller than the volume of the main tank but slightly larger than the inner volume of the bag. After the juice storage container is extended, the main plate and the liquid storage container are separated by a separator plate formed with an injection hole and an air discharge pipe, respectively, so that the juice of the liquid storage container is not affected by gravity even if the water level of the main tank is gradually lowered. Very little madness is achieved to achieve a metered dose of juice.

The present invention has the advantage of preventing the inflow and closing of the flow path and straightening the juice injection flow path, and the cleaning of the juice injection flow path can be easily performed even by non-experts.The use of injection pumps and solenoid valves with high failure rate and cost Since the structure is simple, the cost is reduced, the life is extended, and the quantitative juice is injected into the bag by the quantitative injection device.

In addition, if the juice injection flow path is straight, when the juice injection flow path needs cleaning, open the ball-valve 34 and insert a long cleaning brush into the open juice injection flow path, and then reciprocate up and down to wash. And because cleaning can be achieved simply and comfortably, there is an effect that even non-experts can clean.

In addition, even if the flow path cleaning process does not neglect the hassle and the path (流 路) cleaning, even if the liquid remaining in the flow path cools or hardens, the flow path is straight, so that it can be easily cleaned.

In addition, instead of injection pump and solenoid valve, water-tight and reliable ball-valve and reduction motor are used to prevent leakage or leakage of liquid, and water-tight and reliable ball-valve is used instead of solenoid valve affected by foreign substances. This prevents phenomena such as foreign matters such as grape seeds from clogging the flow path or hindering the flow of juice, and eliminates the problem of having to disassemble and clean the parts or repair (A / S). It is a useful design that works.
