Description

[Detailed description of the invention] This invention is a cylindrical casing made by continuously forming a belt-shaped synthetic resin film into a cylindrical shape, and a nozzle is inserted into the casing to produce solids such as liquid eggs, raw oysters, and konjac. After filling the casing by dropping a different type of filling consisting of solid matter and sealed liquid into the casing, it is squeezed by pressing an ironing roller intermittently at regular intervals, and the areas where solids are not present are squeezed twice with an aluminum wire. In an automatic filling and packaging machine that produces packages of a certain length by ligating and sealing the casing in one place and cutting the casing in the middle of two ligated parts, air may be mixed in, the film at the ligated part may be torn, or solids may be caught during the ligation. The present invention relates to a dissimilar filler supplying device for an automatic filling and packaging machine, which eliminates knots and can obtain packages having a good ligation state.

Conventionally, in order to fill and package such different kinds of fillings with an automatic filling and packaging machine, a belt or chain conveyor, which is equipped with a fixed number of containers containing solids at regular intervals, is continuously rotated to remove the solids from the containers. Materials are intermittently introduced into the nozzle portion, while the filled liquid is continuously supplied to the nozzle portion at a constant flow rate.

In filling and packaging such heterogeneous fillings, the squeezed portion is ligated and cut at two places by pressing a squeezing roller to obtain a package of a certain length, and a closed-bottomed casing to be filled next. However, when the casing is filled with a heterogeneous filling consisting of a solid substance and a sealed liquid, it is preferable that the liquid level of the heterogeneous filling in the casing be located near the middle of the two parts to be ligated. Necessary to obtain a ligated state.

That is, if the liquid level is low, air will be mixed inside the ligated portion of the package, and if it is too high, the film at the ligated portion is likely to tear.

The conventional method was to fill a casing with a fixed number of solids and at the same time fill the casing with a fixed volume of liquid by continuously injecting the liquid at a constant flow rate during the entire time that one package was manufactured. In the case of filling packaging with different types of fillers where the size of solids varies, the liquid level position will fluctuate, resulting in inconveniences such as air being mixed into the package and film tearing at the ligated part. It was easy to use, and many defective packages were produced.

In addition, in such conventional methods, if the size of the solid object is particularly large, the upper surface of the filled solid object will be close to the intermediate position of the ligation part, and the liquid level of the sealed liquid will be pressed by the squeezing roll. At times, since the position is above the position of the squeezing roll, solid matter floats in the liquid, moves above the squeezing roll, and becomes caught in the ligation.

When the filling liquid level is maintained at the intermediate position of the ligature as described above, the above-mentioned jamming will not occur unless the solid is particularly large and the upper surface of the filled solid reaches the intermediate position of the ligature. .

The purpose of the present invention is to maintain the liquid level of the different types of filler at an intermediate position between the ligation parts and to eliminate the disadvantages of the conventional method as described above. The solids and the filled liquid are measured in a metering container to the volume of one product package, and this fixed volume of different types of filling is supplied into the casing through the nozzle to accommodate fluctuations in the size of the solids. Provided is a feeding device for an automatic filling and packaging machine that can maintain the liquid level of a different type of filling at an intermediate position of a ligation part without holding it together, and obtain a package in a good ligation state without air entrainment, film tearing, or biting. It is something to do.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The apparatus for supplying different types of fillings of the present invention passes from a conveyor 2 to which containers containing counted solids are attached at regular intervals to a metering container 8 into which solids are intermittently fed via a hopper 6, from a filled liquid tank 11. Filled liquid is injected by a filled liquid pump 12 through a pipe 4 having a solenoid valve 5 and a hopper 6.

The metering container 8 is a part for determining the volume of the entire heterogeneous filling, and after the solid matter is added, the filling liquid is injected and overflowed to determine the volume.

At the top of the container 8, there is a sliding part 7 (in this example, a vertically movable sliding ring) whose height can be changed so that the volume of the container 8 can be changed depending on the size of the packaged product. attached.

The sealed liquid that has overflowed the sliding part 7 enters the overflow liquid receiving part 23 and is returned to the sealed liquid tank 11 through the overflow pipe 24.

Incidentally, the sliding portion may move up and down integrally with the overflow liquid receiving portion 23.

A shutter 9 is provided at the bottom of the metering container 8.
It is designed to be opened and closed by a rotary solenoid 10.

25 is a backing provided at a portion of the shutter 9 that corresponds to the bottom of the container 8.

The operation of the feeding device of the present invention configured as described above is as follows.

When the shutter 9 at the bottom of the metering container is closed, the package 1
When the individual pieces of solid matter are put into the hopper 6, the electromagnetic valve 5 interlocked with the shutter 9 opens and the sealed liquid is poured.

When the sealed liquid starts to overflow, the volume of the heterogeneous filling consisting of the solid matter and the injection liquid in the metering container 8 becomes constant.

Next, the squeezing rollers 19, 19 approach each other and press the casing, and this portion is ligated with two aluminum fittings 21 by the ligating section cutting section 20, and the casing is cut between the face fittings.

As a result, one package 22 is obtained, and an empty casing 18 whose lower end is closed with one metal fitting 21 is formed.

The squeezing roller 19 opens in conjunction with this ligation section drive.

At the same time, the shutter 9 at the bottom of the metering container is opened, and the weighed dissimilar filling passes through the nozzle section 13 and into the casing 1.
8 is supplied and filled.

The solenoid valve 5 opens and closes in conjunction with the ligation unit drive, and is closed while the shutter 9 is open, stopping injection of the sealed liquid.

Further, the solids are intermittently fed into the hopper 6 from a conveyor with a container at a predetermined period by adjusting its speed.

- In an automatic filling and packaging machine equipped with a supply device devised by a used book, as shown in FIG.
5 forms a casing 18.

The casing, in which the overlapped portions of the films are welded by a high-frequency electrode 16, is sent downward at a constant speed by two pairs of feed rollers 17, 17, and when a certain volume of different types of filling is supplied and filled, the filling inside the casing is The liquid level is maintained at an intermediate position between the ligatures.

When charging solid matter into the metering container 8 with the supply device of the present invention, if it is required to minimize the amount of liquid enclosed in the package 22, which is the product, the amount of liquid in the metering container 8 is The upper surface of the solid should not be convex or the inner wall of the container should not be exposed above the level of the overflowing liquid.

For this purpose, in the present invention, an inverted conical metering container hopper 6 is constructed above the container, and the outlet diameter of the hopper 6 is set to be close to the inner diameter of the metering container and has an appropriate diameter. Depending on the situation, a dispersion plate for uniformly introducing solids may be attached to the metering container hopper 6.

In addition, the piping 4 for injecting liquid into the hopper is located at the center of the hopper to prevent solid matter from being exposed by utilizing the ejection of the filled liquid. A liquid film may also be formed by injecting the liquid onto the inner wall surface.

This is preferable when the type of solid material is one whose surface is likely to be damaged by friction or which is likely to adhere to the inner wall of the hopper.

As described above, according to the present invention, in the production of heterogeneous filled packages consisting of a fixed number of solids and sealed liquid in cylindrical shapes of various lengths with ligated seals at both ends, one package Since different types of fillers are supplied and filled with a constant volume, it is possible to obtain a package with a good ligation state without being affected by fluctuations in the size of the solids, and there is no possibility of air inclusion, ligation film tearing, or There are no ligatures or entanglements of solid objects, and the occurrence of defective product packaging can be significantly reduced.
