Abstract

[Problem] To provide: a transverse seal-forming method capable of filling a liquid object to be packaged without gas bubbles, particles, etc. contained in the liquid object to be packaged intruding into the transverse seal and capable of improving productivity; and a fill packaging machine using said method. [Solution] A method for folding a packaging film, which is fed and driven, back at the center and forming a longitudinal seal on the side edge portion thereof to form the film in a tubular shape, filling a liquid object to be packaged inside said tubular packaging film, and forming transverse seals using a pair of transverse sealing rolls, wherein at least the fold back side of the tubular packaging film is pressed by pressing means provided between each of multiple heat sealing bars located at equal intervals in the circumferential direction of the transverse sealing rolls and transverse seals are formed at said pressing positions using the pair of transverse sealing rolls.

Description

Filling and packaging method and filling packaging machine of the liquid packed material

This invention relates to a filling and packaging machine using a filling and packaging method and the method of liquid material to be packaged, in particular filling and packaging method and filling and packaging machine capable of preventing the biting of the transverse seal portion of the liquid packed material on.

Recently, food by packaging film soft, liquid seasonings, medicines, liquid product cosmetics, viscous or powdery, granular, other have it done is widely to automatically filling and packaging to be packaged.

Automatic filling and packaging machine of such articles to be packaged, for example, as described in Patent Document 1, a packaging film having a laminated structure of a single or biaxially oriented base film layer and the non-stretched sealant layer, or the base film layer a heat-sensitive adhesive layer packaging film comprising the part coated single-layer structure, the folded back at the center portion as the sealant layer or the heat-sensitive adhesive layer on the inside, superimposed side edge portions of the wrapping film, while welded together by applying heat and pressure by a pair of vertical seal rolls feeding downward, by forming a longitudinal seal portion extending in the longitudinal direction, shaping the wrapping film into a tubular shape.

Then, the molded film into the cylindrical, horizontal sealing device, by applying successively heated and pressurized by a plurality of heat seal bars positioned at equal intervals in the circumferential direction around each of the pair of transverse seal rolls feeding downward while welded together, to bag-making packaging bags by the lateral sealing portion extending in the width direction of the wrapping film of the tubular is longitudinally spaced apart intermittently formed of packaging film . At this time, intermittently fed between the continuously the objects to be packaged in packaging the film, or from the formation of one of the lateral seal portions of the tubular packaging film to the formation of the next horizontal sealing portion filled with articles to be packaged in each packaging bag by, unloaded intermediate portion of the laterally sealed portion of the packaging bag is continuously produced by cutting by the cutting mechanism, in the continuous packaging state Tantsutsumi or more follicles are consecutive to.

JP 04-114841 discloses

In such a conventional filling and packaging machine, in forming a lateral seal portion by a pair of lateral seal rolls as described above, folding side portions of the packaging film, after forming the transverse seal portion of the primary, the following a state inflated by spring back until forming a transverse seal portion, the liquid packed material was filled, it is sucked up along the folding side by capillary action, is caught in the next transverse seal portion , there may occur a defective seal.

In forming the transverse seal portion, by performing transverse seal while extruding by a heat seal bar of the horizontal sealing rolls in tubular packaging the film to be packaged, chewing of the lateral seal portion of the packaged articles While suppressing the write is not sufficient, particularly to be packaged is, for example, in the case in which such dressing comprising particulates, etc., can not be extruded granulate such a heat seal bar, horizontal there is a possibility that bitten into the seal portion. With such would be incorporated particulates such as chews the lateral sealing portion, not only unaesthetic, foaming sealing failure occurs occurs, there is a risk that the packaged articles may leak.
