Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multipurpose filling/sealing device that can be used for filling and sealing a wide variety of containers.

In recent years, there has been a remarkable diversification of liquid types and containers in the soft drink industry, etc. In response to this situation, various equipment used for filling liquid into containers has been made compatible. This is behind the increasing increase in the number of people. In filling machines, not only can they accommodate changing container sizes, but they also tend to be used for a variety of liquid types.
A number of filling machines that can meet these demands have been proposed.

On the other hand, in the case of sealing machines for containers after filling with liquid, there is a similar demand for diversification of sealing tools themselves and support for changes in container size. A system in which multiple sealing machines are connected via a container feed star wheel and a container discharge star wheel, respectively, to discharge onto separate discharge conveyors, or a container discharge conveyor from a filling machine is connected via a container feed star wheel and a container discharge star wheel. However, in both cases, the container is supplied to the sealing machine via a star wheel, so there is a risk of the filling liquid spilling out. There are problems such as restrictions on the number of sealing machines installed, and difficulty in adapting to future developments and expansions.

The present invention was proposed in view of the above-mentioned points, and its purpose is to be able to handle filling and sealing of a wide variety of types and diversified containers, to have little liquid leakage, easy maintenance, and to be suitable for the future. It is an object of the present invention to provide a multipurpose filling/sealing device that can be easily adapted to deployment.

The present invention consists of one filling machine, a conveying device connected to the filling machine and conveying the container after filling with liquid, and a conveying device connected to the conveying device and installed at appropriate intervals along the conveying direction of the conveying device. multiple rotary sealing machines,
comprising a means for selectively switching the supply of containers to each sealing machine, and a delivery device installed in parallel with the conveyance device, for sending sealed containers discharged from the plurality of rotary sealing machines to the next process. This is a multi-purpose filling/sealing device that is characterized by: As mentioned above, multiple sealing machines are installed in the container transport device from the filling machine, so there is no need for a star wheel to feed containers to the sealing machine. This eliminates the problem of liquid spillage caused by unsealed containers being transferred by the star wheel after being filled with liquid, and allows the containers to be supplied to the sealing machine selected by the switching means and sealed in the specified manner. We can adjust and maintain other sealing machines, and
As mentioned above, multiple sealing machines are installed between the container conveyance device and the delivery device, which are installed in parallel, making it extremely easy to respond to future developments such as rearrangement and expansion. , it is possible to obtain a multi-purpose filling and sealing device that meets the needs of an increasingly diversified industry.

The present invention will be explained below based on examples.

Fig. 1 is an overall plan layout, Fig. 2 is an enlarged plan view of a part of Fig. 1, Fig. 3 is an enlarged plan view of the switching section, and Fig. 4 is a cross section taken along line A-A in Fig. 3. be.

In the figure, 1 is a rotary filling machine, and conveyor 2
The container 3 sent from the filling machine is supplied via a timing screw 4 and a star wheel 5, and is filled with liquid as the filling machine rotates.
The container 3 after being filled with liquid is delivered onto a container conveying device 6 installed tangentially to the filling machine.

The container transport device 6 includes a container rail 7 that supports the bottom of the container 3, one front guide 8 and an opposite guide 9 installed on both sides of the rail 7, and the container rail 7.
Chain 1 installed to run along
0, and carriers 11 attached to the same chain 10 at predetermined intervals.

12a, 12b, 12c, 12d are conveyance devices 6
A plurality of rotary sealing machines are installed at appropriate intervals along the conveyance direction of the same conveyance device tangentially to the conveyance direction, and each seals a different sealing tool. Each sealing machine is of a known type, and as shown in FIG. 4, has a rotary table 13, a container holder 14, etc., and the rotary table 13 is flush with the container rail and can be selectively attached. The container is guided from the conveying device 6 by the switching guide 15, which is configured as shown in FIG.

Note that the facing guide 9 is partially omitted so that containers 3 can be supplied to each sealing machine.

Reference numeral 16 is for sending the sealed container 3 to the next process by a container delivery device after sealing, which is installed parallel to the container transport device 6 with each sealing machine in between.

17a, 17b, 17c, 17d are each sealing machine 1
2a, 12b, 12c, 12d is a star wheel that transfers the sealed container 3 onto the delivery device 16.

Note that 18a, 18b, 18c, and 18d are known sealing tool supplying chute that supply sealing tools to be sealed by each sealing machine to the mouth of the container 3.

In the above configuration, the container 3 sent by the conveyor 2 is supplied to the filling machine 1 via the screw 4 and the star wheel 5, and is filled with various liquids. The container filled with the liquid is sent onto the transport device 6, and the chain 10 runs to transport the container to the carrier 11.
The paper is transported to the sealing machine via the

Here, the sealing machine corresponding to the container is selected. For example, when sealing is performed with the sealing machine 12b, the switching guide 15 is attached as shown in the figure, so the container that has passed through the sealing machine 12a without passing through will be moved to the guide 15. It is guided and supplied to the sealing machine 12b, and the holder 1
4 and is rotated by the rotary table 13, while being sealed in a known manner. Although this embodiment shows an example in which the sealing tool is supplied to the mouth of the container while being transported on the transport device 6, the present invention is not limited to this, and the sealing tool may be supplied to the mouth of the container after being supplied to the sealing machine. Of course, a sealing tool may also be provided.

The sealed container is transferred onto the delivery device 16 via the star wheel 17b and sent to the next process.

On the other hand, when sealing different sealing tools or containers of different sizes, the switching guide 15 can be switched to select and switch the sealing machine corresponding to the sealing tool or container. We can perform size changes and maintenance of sealing machines.

Therefore, it is easy to handle a wide variety of containers, and since each device is arranged as described above, it is easy to handle rearrangement and expansion for future developments. Moreover, since the container supply star wheel for each sealing machine is not required, there are many advantages such as simplification of the configuration, cost reduction, and prevention of liquid spills during star wheel transfer.
