Description

[Detailed Description of the Invention] The present invention relates to a liquid filling device particularly suitable for liquids containing alcohol such as alcoholic beverages.

Recent liquid filling devices aim to speed up the filling process, and a vacuum method or a pressurization method is being adopted. However, in the case of liquids containing alcohol, the vacuum method causes degassing of the alcohol, and the pressurized method has drawbacks such as bubbling and the liquid spilling out of the bottle.
In addition, with conventional filling equipment, the height of the filling nozzle and bottle must be adjusted for each head each time the type of bottle changes, which is extremely troublesome and hinders the speed of filling operations. Ta.

It is an object of the present invention to provide a liquid filling device equipped with a filling nozzle that can speed up filling using the so-called gravity fall method and can quickly respond to changes in bottle types.

The present invention includes a plurality of filling nozzles provided on a circumference of a desired diameter in a substantially vertical state and equally spaced in the circumferential direction; In a liquid filling device that includes a liquid tank for supplying liquid and injects the liquid from the filling nozzle into a container sent directly below the filling nozzle, the liquid is disposed between the liquid tank and the filling nozzle. A measuring cup for receiving a predetermined amount of liquid from the tank is provided for each filling nozzle and is connected to the corresponding filling nozzle, and each filling nozzle includes a vertically extending cylindrical member forming a liquid passage, and a measuring cup for receiving a predetermined amount of liquid from the tank. a rotatable adjustment shaft disposed adjacent and parallel to the cylindrical member and having a sprocket attached thereto; an outer cylinder that is telescopically fitted in the cylindrical member and is threadedly connected to the adjustment shaft; A valve mechanism is attached to the lower end of the outer cylinder and opens when it comes into contact with the mouth of the container, and the sprocket of each filling nozzle is engaged with a common endless chain, so that the plurality of adjustment shafts can be rotated simultaneously. It is configured as follows.

In the above configuration, a predetermined amount of liquid is supplied into the measuring cup from the liquid tank. Once the container is fed under the fill nozzle, the fill nozzle is lowered and a valve mechanism opens to inject the liquid contained in the measuring cup into the container. When adjusting the vertical positions of the outer cylinder and the valve mechanism, it is sufficient to rotate any one adjustment shaft.

The present invention will be explained below with reference to the drawings. FIG. 1 shows the entire apparatus according to an embodiment of the present invention. The liquid filling device 1 includes a filling nozzle section 2, a liquid tank 3, a switching valve 4, a measuring cup 5, a conveyor 6, and the like. The injection of the filling liquid filled into the tank 3 is electrically controlled.
A timer 72 is activated in response to a signal from a cam-activated microswitch 71, and the operating time of this timer 72 determines the filling amount. The timer 72 is the solenoid valve 7
3 to energize the cylinder 74,
Due to the force of 4, the switching valve 4 is opened and the tank 3 is opened.
The filling liquid inside is supplied into the measuring cup 5. When the timer 72 turns OFF, the switching valve 4 is closed via the solenoid valve 73 and the cylinder 74, and the tank 3 is closed.
The supply of filling liquid to the measuring cup 5 is then stopped.
The lower end of the metering cup 5 communicates with the filling nozzle part 2 via a flexible tube 8.

The device of the present invention includes a plurality of filling nozzle parts 2, and an adjustment shaft 21 for adjusting the injection position of the filling nozzles.
are designed to interlock with each other via sprocket 22 and chain 32. Bottles A filled with a liquid containing alcohol are placed on a conveyor 6 and continuously transported.

FIG. 2 shows the filling nozzle part 2 in detail. A helical screw 31 is formed on the outer periphery of the lower part of the adjustment shaft 21, and this helical screw 31 is connected to a female screw 33 formed inside the support bracket 30 of the outer cylinder 23 that forms a liquid passage extending in the vertical direction. engaged. Therefore, by turning the upper end 40 of the adjusting shaft 21 with the handle, the bracket 30 moves up and down under the action of the helical screw, thereby changing the height of the filling nozzle. Furthermore, a sprocket 22 is fixed near the center of the adjustment shaft 21, and a chain 32 is attached to the sprocket 22 so as to interlock the adjustment shafts for correcting the heads of each filling nozzle (Fig. 3). The upper end of the adjustment shaft 4
Just by rotating 0, the heads of all adjustment axes will be corrected.

The lower end of the flexible tube 8 is a hollow conduit 24
The hollow conduit 24 is inserted and fixed into the outer cylinder 23. At the bottom of the outer cylinder 23, there is a valve mechanism 25 that opens only when it comes into contact with the mouth of the container A.
is provided.

FIG. 4 shows details of the valve mechanism 25.
A bottom cover 36 provided with a plurality of holes is attached to the lower end of the outer cylinder 23, and a shaft 37 extending downward is fixed to the bottom cover 36. A valve member 39 containing an elastic material 38 such as rubber is provided at the lower end of the shaft 37.
is installed. On the other hand, a holder 26 extending into a cylindrical shape is slidably attached to the outer periphery of the outer cylinder 23, and a lower surface 35 of the holder 26 is formed into a conical shape and comes into contact with the opening of the container A. A guide tube 29 is attached to the lower end of the holder 26 and extends further downward, the lower end 42 of the guide tube 29 forming a valve seat that engages sealingly with the elastic material 38 of the valve member 39.

A spring 28 is attached between the spring receiver 27 fixed to the outer cylinder 23 and the holder 26, and the holder 2
6 is always biased downward. In the state shown in FIG. 4, the holder 26 is at its upper limit position and comes into contact with the spring receiver 27 and stops, and the valve seat 42 and valve member 39
The liquid is injected in the direction of the arrow with a distance between the two. At the lower limit position of the holder 26, the valve seat 42
The valve member 39 stops in contact with the valve member 39, and no liquid is injected.

To explain the operating sequence of the valve mechanism 25, first, when the container A is conveyed by the conveyor 6, the filling nozzle part 2 descends toward the mouth of the container A. At this point, the holder 26 is in its lower limit position and the valve 26 is in its lower limit position.
5 is in the closed state.

The filling nozzle part 2 is lowered to the lower surface 35 of the holder.
When the holder 26 comes into contact with the mouth of the container, the holder 26 stops descending, but the outer cylinder 23 continues to descend while compressing the spring 28. This opens the space between the valve seat 42 and the valve member 39, allowing liquid to flow into the container.
The descent of the outer cylinder 23 stops at the position where the holder 26 contacts the spring receiver 27.

When the filling time set by the timer 72 (FIG. 1) has elapsed, the outer cylinder 23 rises, the gap between the valve seat 42 and the valve member 39 closes, and the inflow of liquid stops.
The filling nozzle part 2 returns to its initial raised position. Thereafter, similar steps are repeated to continuously fill a large number of containers with liquid.

As is clear from the above explanation, according to the filling device of the present invention, each adjustment shaft is interlocked via a sprocket and a chain, so adjusting any one adjustment shaft simultaneously adjusts all the heads. This makes it possible to quickly respond to changes in bottle types. In addition, since the liquid is filled by gravity falling, there is no spillage due to alcohol degassing or foaming, and an economical, hygienic, and efficient filling device is provided.
