Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a filling and packaging device for injecting contents such as alcoholic beverages and juices into containers.

In particular, the present invention relates to a container transport device that transports containers in order to perform various treatments on the containers.

[Prior Art] As the above-mentioned filling and packaging apparatus, one is known that is constituted by two apparatuses: a container bottom forming apparatus and a forming and filling apparatus.

The container bottom forming device folds in one end, for example, one end P of a cylindrical container material made of a laminated material mainly made of paper and has both ends open, so-called sleeve material 1 (Fig. 3), and roughly forms the armpit part. This is an apparatus for forming a container 2 with a bottom (FIG. 4) having a bottom Q by sealing the container.

The forming and filling device has a container transport device, for example a transport chain, for transporting the bottomed container 2 . Around this container conveyance device, especially above it, a top breaker, a contents filling device, and a top heater are arranged in order according to the conveyance direction of the conveyed containers.

Various equipment such as a top press will be installed.

The container 2 with a bottom formed by the container bottom forming device is
The container is received by the container transport device at a predetermined container receiving position, and thereafter is intermittently transported in an upright state with the bottom Q facing downward. During this intermittent conveyance, the top opening R of the container 2 is temporarily folded by the top breaker, and the contents, such as alcohol, juice, etc., are poured into the container by the contents filling device through the temporarily folded top opening R. Injected.

After that, the top R of the container is further heated by a top heater to give adhesiveness to the armpit, and the top opening R is sealed by a top press device using the adhesiveness, and finally the contents of the product are Container 3 (l[5
Figure) is manufactured.

Conventionally, the above-mentioned container transport device uses a ring-shaped transport chain to transport the containers, and a transport rail is provided below the transport chain.

There is a device that receives the container 2 being transported from below.

In the forming and filling apparatus, as is clear from the above description, temporary folding of the top of the container 2 and other processes are performed from above the container 2 being transported.

This means that the container bottom Q, which is received by the transport rail, is at the reference height position for each of the above processes.

In the conventional container conveying device, the bottom portion of the container is transferred from the container bottom forming device to the bottom part! The height of the conveyor rail installed between the container receiving position where the container 2 is received and the container 3 containing the contents as a product is created is set to a constant height over the entire length.

[Problems to be Solved by the Invention] However, in the conventional container conveying device in which the height of the conveying rail is set constant over the entire length, the bottom-equipped container 2 formed by the container bottom forming device is When transferring the container to the transport device, due to dimensional errors in the sleeve material 1 and other various causes, the container bottom Q may not accurately contact the transport rail, and the container 2 may float slightly above the transport rail. Ta. When this condition occurs, the height of the top of the container will vary, and there is a risk that the containers will not be processed accurately by the various devices placed above the container transport path, such as the top breaker and top heater. .

The present invention has been made in view of the above-mentioned problems in conventional container transport devices, and is a container transport device capable of accurately holding the tops of individual containers that are sequentially transported at a constant height. The purpose is to provide

[Means for Solving the Problem] In order to achieve the above object, the container conveying device according to the present invention has a container receiving position (Sl) for receiving the container with a bottom (2) from the container bottom forming means (8). to the position corresponding to the top breaker (first top breaker 20) (container top segregation position S2) (transfer rail (4))
is characterized in that the height is lower than the height of the conveyor rail (4) at the container top segregation position (Sl).

[Operation] In normal work, the bottom (Q) of the container (2) that is transferred from the container bottom forming means (8) to the container conveying means (container conveying chain 17) comes into contact with the conveying rail (4). be transported to.

Since the height of the transport rail (4) at the container receiving position (Sl) is lower than the height of the transport rail (4) at the container top segregation position (Sl), the height of the transport rail (4) at the container receiving position (Sl) is lower than the height of the transport rail (4) at the container top segregation position (Sl). The height of the container (2) transported from ) to the container top segregation position (Sl) increases by the difference in height of the transport rail (4). This elevated position is the reference height position of the container (2) being transported.

If there is a dimensional error in the sleeve material (1) or if there is any other cause of abnormality, the container receiving position (Sl
), an abnormal situation may occur in which the bottom (Q) of the container received from the container bottom forming means (8) to the container conveying means does not come into contact with the conveying rail (4) and floats slightly upward. In this case, since the conveyance rail (4) is lower than the standard height in advance, until the conveyed container reaches the container top temporary folding position (Sl), the container bottom (Q
) remains floating from the transport rail (4). However, the height of the conveyor rail is limited to the temporary folding position of the top of the container (
The height increases as the container approaches the container top folding position (Sl), so that when the container reaches the container top temporary folding position (Sl), the bottom of the container comes into contact with the conveyance rail.

In this way, even if there is variation in container height at the container receiving position (Sl), the container height at the container top temporary folding position (Sl) is always the same as that at the container bottom (Q).
can be set to a reference height at which the rail contacts the conveyor rail (4).

[Example 1] FIG. 1 shows the entire filling and packaging apparatus using a container conveying apparatus according to the present invention. This filling and packaging apparatus is broadly divided into a container bottom forming apparatus 8 and a forming and filling apparatus 9.

The container bottom forming device 8 has eight mandrels 12 arranged radially, and the sleeve material 1 is sequentially inserted and fitted onto the outer periphery of these mandrels 12 one by one.

Each mandrel 12 rotates intermittently in the direction of arrow B around the center block 12a. During this intermittent rotation, the outer open end P of the sleeve material 1 fitted into one mandrel 12 is sequentially heated by the first heater 13 and the second heater 14 to give it adhesive properties. and,
The open end P is folded in by the bottom folding device 15, and the folded portion is further pressed by the bottom press device 16. During this pressing process, the end surfaces of the sleeve material are adhered to each other due to the adhesiveness imparted to the open end portion P of the sleeve material 1 as described above, and the bottomed container 2 (
FIG. 4) is formed.

The container 2 thus formed is pulled out downward from the mandrel 12 when the mandrel 12 rotates to a position facing vertically downward and stops.

The forming and filling device 9, which is another device constituting the filling and packaging device, has a container conveyance chain 17 stretched in an annular shape. This conveyance chain 17 is adapted to rotate in the direction indicated by the arrow, and a large number of conveyance pieces 18 are attached to the outer surface of the conveyance chain 17 at equal intervals.

Further, below the conveyance chain 17, a conveyance rail 4 is provided.
It is installed along the circumferential direction of the conveyor chain 17.

The container 2 with a bottom pulled out from the mandrel 12 is sequentially lowered between the two conveyor pieces 18 with the bottom Q (FIG. 4) facing downward, and as the conveyor chain 17 rotates, the conveyor piece 18 and is intermittently conveyed linearly in the direction of the arrow while sliding on the conveyance rail 4.

The container 2 transported in this way is made up of a pair of triangular press pieces 1
The top R (FIG. 4) is temporarily folded by the first top breaker 20 having a diameter of 9.

The contents of the liquid tank 22, for example, sake, are then poured into the container 2 whose top has been temporarily folded through the first filling nozzle 21a and the second filling nozzle 21b.

The container 2 into which the contents have been poured is then temporarily folded by a second top breaker 24 equipped with a pair of triangular press pieces 23, and then the first folded top is heated by a heater 25. be done. This heating causes
The top of the container is sticky. The container 2 after the heat treatment is folded and pressurized by the top press device 26, and as a result, a container 3 with contents as a product having a mountain-shaped top as shown in FIG. 5 is manufactured. Ru. This product container 3 is removed from the conveyor chain 17 by a container discharge device (not shown) and discharged to the outside.

The above filling and packaging equipment, especially the forming and filling equipment! 9, as shown in FIG.
The height of the conveyance rail 4 up to the first temporary folding position S2 where the top breaker 20 is arranged is a height H higher than the height of the conveyance rail 4 at the position corresponding to the second temporary folding position S2. The height is reduced.

Therefore, when the bottom part Q of the container 2 pulled out from the mandrel 12 is placed in the normal position where it contacts the transport rail 4, when the container 2 being transported in the direction D reaches the primary segregation position S2, The container 2 is lifted upward by the difference in height of the transport rail 4 and set at the primary segregation position S2. This position becomes the reference height position for a series of filling and packaging processes to be performed on the container 2 from then on.

On the other hand, due to dimensional errors in the container 2 and other various causes, the bottom portion Q of the container 2 may not come into contact with the upper surface of the transport rail 4 at the container receiving position S1, but may be slightly floating. In this embodiment, even in such a case, when the container 2 is transported to the primary segregation position S2, the container 2 is lifted up to the reference height position by the transport rail 4, as in the normal case described above. Therefore, filling and packaging processing by various devices arranged above the conveyance path of the container 2 can be performed normally without any trouble.

Although the present invention has been described above with reference to one embodiment, the present invention is not limited to that embodiment.

For example, the configuration of the container bottom forming device 8 is not limited to the configuration shown in FIG. Can be adopted.

Also in the forming and filling device 9, on the downstream side of the top breaker, that is, the first thump breaker 20, if necessary,
Any other equipment other than the equipment shown in FIG. 1 can be added.

[Effects of the Invention] According to the present invention, even when there are variations in the height of the containers received by the container transport means at the container receiving position (Sl), the containers are located at the position corresponding to the top breaker (at the top of the container). When the paper is transported to the temporary folding position S2), its height is always set to the reference height. Therefore, the bottomed container (2) can always be transported at the same height without variation.
