Abstract

PROBLEM TO BE SOLVED: To eliminate a sealing defect causing object at a heatsealing position, and prevent a sealing defect due to being caught from generating, by providing a film thrusting up body which thrusts up the heat sealing location of a film. SOLUTION: A heat-sealing location P of a film 1 is thrusted up before a heat-sealing by a thrusting up body 20. When the thrusting up body 20 is a plate-form, both the length direction of the leading end plate edge and the width are made to roughly meet the heat-sealing location P. The heat-sealing location P is thrusted up by the film thrusting up body 20, and leading end plate edge of the thrusting up body 20 is pushed in from the lower side of the film 1, and the lower side part of the film 1 is lifted inward into a mountain- shape so that the heat-sealing location P may become the ridge. By doing so, when there is a chip of an article 3 to be packaged at the heat-sealing location P, the chip is eliminated by tilting and sliding so that the chip may be sorted by the thrusting up. By the elimination of the chip, a sealing defect due to being caught, is prevented from generating.

Field of the Invention The present invention relates to a sealing device in a packaging device for heat-sealing a film by sandwiching a position of the film in which a package is stored at a predetermined interval from the outside of the film. It is.

Description of the Related Art A sealing device in a packaging device intermittently conveys a tubular film containing articles to be packaged at predetermined intervals, for example. Once the film transport is stopped, the position between the wrapped objects of the film is clamped from outside of the film by this clamping body, and the film is welded by the heat of the heater at the front end surface of the clamping body. The intermediate positions are sequentially sealed, and, for example, the middle part of the heat sealing position is further cut off and intermittently conveyed so that the packaging bags containing the articles to be packaged are sequentially carried out.

一定となるようにし常にフィルムの被包装物と被包装物

と、熱シール不良をきたすおそれがある。[0003] However, even if the distance between the objects to be packaged is always kept constant and the intermediate position of the film between the objects to be packaged can be reliably held and heat sealed, it is possible to control the heat sealing. If there is dust or the like in the position to be packaged, there is a risk of causing poor heat sealing.

おそれがある。[0004] That is, for example, if the object to be packaged is such that debris such as mushrooms easily come out, small pieces of mushrooms, debris at the portion with a stone, or soil may come out in the film. Even if the mushroom itself is not pinched, if such debris is pinched and pinched together with the film and heat-sealed, the heat welding of the films becomes insufficient, and the sticking is peeled off after bag making, or it is completely welded. There is a risk of causing poor sealing such as not performing.
