Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention applies a strip-shaped film in a groove-shaped shaping mold to shape the film into a groove-shaped shape, while supplying an object to be packaged onto the film. Further, the present invention relates to a packaging device in which both sides of the groove type film are welded in a palmar shape by a center sealer to form a tubular shape, and the object to be packaged is wrapped in the tubular film.

(Prior Art) Conventionally, as shown in FIG. 5, a film (4) is formed by a groove-shaped shaping mold (3) supported on a machine base (2) via a stay (1).
Is shaped into a groove, while the material to be packaged (5) is supplied onto the groove-shaped film (4), and the material to be packaged (5) is also supplied.
While pressing the holding plate (6) downward, both sides of the film (4) are overlapped above the holding plate (6) in a palm-shape,
There is provided a product in which the overlapped portion is heat-welded so that the article to be packaged (5) is packaged in a tubular film (4).

(Problems to be solved by the invention) However, in the above-mentioned device, if the object to be packaged has a thin leaf tip or root such as "green onion" or an elongated object such as a thousand radish or sprouts, the object to be packaged is When (5) moves integrally with the film (4), a part of it is shaped (3)
The food is eroded from the gap between the holding plate (6) and the holding plate (6), and the food is caught between the ridges on both side edges of the film, which causes poor sealing of the ridges and a decrease in commercial value.

In view of the above points, the present invention provides an apparatus for compressing and packaging a part of an object to be packaged, such as fluffy vegetables, so as not to be caught in the palm of the film.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a groove-shaped shaping die for forming a groove-shaped film and an object to be packaged supplied on the groove-shaped film. In a packaging device comprising a pressing plate having an arc-shaped cross section provided in the shaping mold for pressing from above, and a center sealer for welding both side edges of the film in a palmar shape at the upper rear part of the pressing plate, Is provided with a film sliding plate having an arc larger than that of the pressing plate.

(Operation) According to the present invention, both side edges of the film formed in the groove shape by the shaping mold are slid on the sliding plates provided on the holding plate and are overlapped with each other in a palm shape and are welded, It is made into a tube so as to wrap the object to be packaged. In this case, the upper sliding plate has a larger circular arc than the lower pressing plate of the arc type cross section, and a gap is formed between the pressing plate and the film sliding plate on both sides. Even if a part of the packaged item projects from between the shaping mold and the holding plate, a part of the packaged item does not project above the film sliding plate.
In short, the pressing plate presses the article to be packaged, while the film is made into a tube so as to be lifted by the sliding plate, and a part of the article to be packaged is prevented from being caught in the film welding portion.

(Example) As shown in FIGS. 1 to 3, a groove-shaped shaping die (10) is horizontally supported on a machine base (12) through a stay (11), and a film (F) is rolled. It is shaped into a groove by pulling in the direction of the arrow (14) along the shaping mold (10) via the (13), and the article (A) to be packaged is supplied into the groove-shaped film. The holding plate (16) and the film sliding plate (17) provided on the machine base (12) via the stay (15) in the shaping mold (10) are the same as the holding plate (16) as shown in FIG. The film sliding plate (17) is bent into a small arc shape, while the film sliding plate (17) is bent into a larger arc shape. And as shown in FIG. 1, the object to be packaged (A) is placed in the shaping mold (10) and the lower holding plate (16) is placed.
On the other hand, both side edges (F1) (F2) of the film (F) formed in a groove shape as shown in FIG. 3 are attracted by sliding on the upper surface of the sliding plate (17). (18) (18) are stacked in a chisel shape and welded by center sealers (19) (19).

(Effect) The present invention provides a film slide plate (17) having a larger cross-section arc than the holding plate (16) of the packaged object in the shaping mold (10), and holding plates at both sides. Since a gap is formed between the package and the package so that a part of the package does not protrude upward, the effect of being able to wrap the capillary package with the film without biting the package is there.
