Description

[Detailed description of the invention] Industrial applications The present invention relates to a packaging device.

BACKGROUND OF THE INVENTION Traditionally, products have been wrapped in a film that is folded in half, and the open end is heat-sealed. This type of film is generally wound into a roll, and both sides of the film pulled out from the film roll are in close contact with each other. Therefore, in order to wrap products with this film, it is necessary to release the film in some way and open it.

Some conventional packaging devices have a structure as shown in FIG. 6, for example, as a means for opening a film folded in two. In FIG. The film guide plate 25 is a plate-shaped film guide plate fixed on the main body 1. In FIG. Then, the film guide plate 25 is inserted inside the folded film.

By pulling out the film 7 from the film roll and moving it to the left while sandwiching the film guide plate 25,
The tightly adhered films 7 are peeled off one after another by the film guide plate 25. Then, the operator lifts the upper piece 7a of the film 7 and inserts the object to be packaged, for example, a green onion, into the inside of the film 7 as shown in FIGS. 7 and 8.
It is placed in the recess 16 and sealed by closing the sealing device 9 shown in FIG.

Problems to be Solved by the Invention However, in the above configuration, the packaging film 7
Although the upper and lower pieces of film 7 that are in close contact with each other can be peeled off by the film guide plate 25, it is necessary for the user to lift the upper piece of the film 7 by himself or herself when inserting the object to be packaged. Also, depending on the properties of the film and the packaged item, the film may adhere to the packaged item, especially when packaging agricultural products such as green onions as in this example, the agricultural products are often wet. In such cases, the film is very likely to adhere to the packaged item. If the film adheres to the packaged item in this way, the upper and lower pieces may become misaligned or wrinkles may occur in the film. Therefore, when inserting such a packaged item, the user must lift the top piece of the film sufficiently to prevent the film from sticking to the packaged item (this makes the process very complicated). Ta.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a packaging device that can smoothly perform packaging operations without causing shifts or wrinkles in the film.

Means for Solving the Problems In order to solve the above problems, the present invention includes a first side plate and a second side plate as a film guide plate, and
A member having an opening is provided on the open end side of both side plates, and the packaging film is pulled out by sandwiching the film guide member so that the opening of the film guide member corresponds to the open end of the packaging film. In addition, a guide rod was constructed between the first side plate and the second side plate of the film guide member.

Operation With the above-described structure, the upper and lower pieces of the open end example of the packaging film are guided by both side plates of the film guide member and can be widened, allowing the packaged item to be wrapped around the film. By inserting through the opening of the guide plate and moving it along the direction of travel of the packaging film, the item to be packaged can be inserted smoothly inside the packaging film, and the guide rod can guide the item to be packaged. However, it is possible to prevent the object to be packaged from coming into contact with the upper and lower pieces of the packaging film that have not yet fully spread.

By moving the green onion 26 to the left, the film 7 is further pulled out from the film roll. When the film 7 moves, the fold line of the film 7 folded in two moves along the connecting portion 21e of the film guide plate 21. The film 7 is guided by both side plates of the film guide plate 21, that is, the lower plate 21a and the upper plate 21c, and the upper piece 7a and the lower piece 7b are opened one after another. At this time, the film guide plate 20 prevents the film 7 from slipping off the film guide plate 21.

Once the film 7 has been pulled out sufficiently, the leaves of the green onion 26 are also inserted into the film guide plate 21 in the same way. FIG. 4 shows the state at that time. If 26 green onions
Even if the leaf part of the green onion 26 is not moved sufficiently to the left and the leaf part tries to protrude from the film guide plate 21, the leaf part of the green onion 26 will first hit the guide rod 23 before being accommodated inside the film guide plate 21. Therefore, the leaf part of the green onion 26 is blocked by the guide f'J23 and does not hit the part of the film 7 that has been pulled out from the film roller and has not been fully opened. In other words, the leaves of the green onions 26 do not hit the upper and lower pieces 7a and 7b of the film 7 at the portions that are not fully opened, thereby preventing wrinkles or the like from forming on the film 7.

After inserting the leaf part of the green onion 26 inside the film guide plate 21, if the green onion is further moved to the left, the entire green onion will be covered with the film 7.

Then, the green onion 26 wrapped in the film 7 is placed in the recess 16 as it is. At that time, green onion 26 wrapped in film 7
is regulated by the guide plate 25 and brought to the individual wall of the recess 16 on the side of the horizontal sealing underlay member 15 . And film 7
The open end side excess portions of the upper piece 7a and the lower piece 7b are located above the vertical sealing underlay member 14 and the horizontal sealing underlay member 15.
