Description

[Detailed description of the invention] [Industrial application field] This invention is for container transportation used in a container manufacturing line that includes the process of covering the opening of a foil container with a film-like lid and turning the lid. Concerning palette improvements.

Note that the film shape here also includes sheet shape.

[Prior Art] For example, popcorn in a container has been commercially available in which popcorn ingredients are stored in the container and the upper opening is covered with a film-like lid made of cellophane or the like. As shown in the plan view and cross-sectional view in FIGS. 2 and 3, this type of popcorn in a container stores popcorn material 2 in the bottom of a dish-shaped foil container 1 made of metal foil such as aluminum foil. It is covered with a film-like lid 3 made of cellophane or the like, and its peripheral portion is wrapped around a frame 4 made of wire or the like. In the tightened state, as shown in FIG. 4, which is an enlarged view of the area indicated by circle A in FIG. The structure is such that the parts are wrapped around each other. Popcorn in a container is
Because it has the above-mentioned structure, it is manufactured through various processes, but the focus of the present invention in these processes is that the film-like lid is covered with the container, and then caulked (the periphery is tightened). This is a moving process until the final step is reached. That is, during this time, the container and the lid move on the production line, and attention will be paid to how the film-like lid maintains a fixed positional relationship with the container during this movement.

[Problems to be solved by the invention] By the way, it is difficult to ensure the relative positioning of the film-like lid and the container, so it is difficult to ensure that the opening of the container is closed with the film-like lid. There were disadvantages such as the occurrence of defective products that were not made properly, and the need to make the film-like lid larger than necessary.

This device was devised in order to effectively solve the above-mentioned problems, and its purpose is to position the film-like lid relative to the container and reliably maintain that position. It is an object of the present invention to provide a pallet for conveying containers that enables processes such as caulking to be performed and contributes to improved productivity.

[Means for Solving the Problems] The pallet for conveying containers according to this invention has a shape with an open top, and has a foil container placement section in the center and a film-like lid above it. The lid holder has a lid holder that holds the body, and the wall surface around the lid holder is inclined so that the upper opening becomes narrower as it goes upward. After being pushed into the holding section, the foil container is transported while ensuring that the lid is positioned above the foil container.

[Embodiment] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a side sectional view showing a schematic configuration of an embodiment of this invention. As shown, Palette 5
has a shape with an open top, and a foil container 1 (shown in phantom lines) and a film-like lid 3 (shown in phantom lines) made of cellophane or the like are inserted through the top opening 6. A lid holding section 7 for holding the film-like lid 3 is constructed above the pallet 5. This lid holding part 7 is attached to the pallet 5.
The annular seat part 8 is formed on the upper periphery of the annular seat part 8, and the peripheral side wall 9 is erected on the outer circumferential side of the annular seat part 8 and is inclined so that the diameter of the upper opening 6 decreases as it goes upward. It is structured as follows. As a result, the film-like lid 3 pushed into the lid holder 7 will not be displaced or blown off even if the pallet 5 moves at a certain speed, and will not be blown off into the container 1. A constant positional relationship can always be maintained.

On the other hand, at the center of the inside of the pallet 5, a container mounting part 10 made of a cylindrical wall is formed to protrude upward. A rubber ring 11 is attached to the inner periphery of this container placement part 10, and the container 1 to be placed is placed in contact with the inner periphery of this rubber ring 11, and is roughened by manual work. It is configured so that it is always set in a constant position and posture even when placed in the same position. At the upper end of the container placement part 10, a ring member 12 is provided which presses and fixes the rubber ring 11 on the lower end surface and forms a mold surface on the upper end surface.
is installed. The container 1 has a flange portion 13 formed on the periphery of its opening that extends radially outward and approximately horizontally, and is configured such that the flange portion 13 is placed on the upper end surface of the ring member 12. There is. In addition, a notch 14 is formed along the circumferential direction on the inner peripheral side of the upper end surface of the ring member 12, and when the container 1 is placed, the side wall 15 of the container 1 and the flange portion 13 are connected. It is configured to form a space outside the boundary portion. Therefore, the degree of caulking can be adjusted as appropriate during the caulking process. Further, a knockout plate 16 is provided below the foil container 1 placed on the pallet 5, and this knockout plate 16 pushes the pin 17 from below after all processes are completed. By doing so, container 1 can be placed on pallet 5.
It is provided for taking out from.

Note that the film-like lid may be a flat plate made of paper, and in addition to closing the lid by caulking, it can also be applied to other devices such as shrink-linking and heat-sealing. Furthermore, the contents are not limited to popcorn.

[Effects of the invention] As is clear from the above explanation, this invention provides the following excellent effects.

That is, a lid holder is provided at the top of the pallet, and the wall surface around the lid holder is sloped so that the upper opening narrows as it goes upward.
The film-like lid held by this will not shift or blow off even if the pallet moves at a considerable speed, and will be transported while ensuring that it is accurately positioned relative to the container. As a result, products can be manufactured with high yield without requiring any manpower.

[Brief explanation of the drawing]

[Claims for Utility Model Registration] A lid closing device for transporting a foil container that covers the opening of a foil container with an open interior and an opening at the top with a film-like lid. The pallet has an open top, a foil container placement part in the center, and a lid holding part above the foil container holding part for holding the film-like lid. The wall surface around the part is inclined so that the upper opening becomes narrower as it goes upward, so that when the film-shaped lid is pushed into the lid holding part and then transported, the lid is A pallet for conveying containers, characterized in that the pallet is conveyed while ensuring that the body is positioned above the foil containers.
