2. Description of the Related Art Conventionally, as a packaging device of this type, there is known a filling and packaging machine which fills and seals soy sauce, horseradish or mayonnaise, which is an object to be packaged such as a liquid or a viscous substance. Generally as a filling and packaging machine,
A pair of holding frames is provided on the side of the main body of the packaging machine, and the film roll wound with the film is held on the holding frames in a detachable and replaceable manner, and the film guide mechanism and the film are provided on the upper part of the machine base. A folding mechanism is provided, and a vertical sealing mechanism, a horizontal sealing mechanism, and a cutter mechanism are provided from the upper side on the front surface of the machine base. The film is pulled out from the rewinding roll and led out to the film folding mechanism via the film guiding mechanism. Then, the film is folded in two in the longitudinal direction by the guide provided in the film folding mechanism, and the folded end portions of the film are folded by the respective vertical seal members provided in the pair of vertical seal rolls facing the vertical seal mechanism. Is heated under pressure and fed while being vertically sealed, and the film is formed into a tubular shape by this vertical seal, and the film is formed in the opposite direction of the horizontal sealing mechanism. The horizontal seal members provided on the horizontal seal rolls laterally seal the film in a horizontal direction while applying pressure and heat, and the bottom is formed by the horizontal seals, thereby forming a bottomed tubular film. Two filling nozzles provided in the filling mechanism are used to fill two types of objects to be packaged, for example, soy sauce and horseradish, and the film is sent again to the film by the horizontal seal member provided on the horizontal seal roll of the horizontal seal mechanism. It is known that a bag is obtained by laterally sealing the bag mouth side of each of the objects to be packaged and cutting the laterally sealed portion with the cutter mechanism.

In such a filling and packaging machine, the thickness and width of the film or the material of the film are selected according to the packaging form of the packaging bag to be produced, and the sealing temperature, the sealing speed, the filling amount, etc. are produced in accordance with this. The conditions are to be determined, and in order to perform good heat sealing under these production conditions, a packaging film is formed into a tubular bag by the vertical sealing members of the pair of vertical sealing rolls, and then the pair of horizontal sealing rolls. The film is sandwiched between the horizontal sealing members of the above, and the film is pressed and heated to expel the liquid or viscous substance inside the film upwards or downwards (while squeezing out), and then the film is cured. Therefore, it is configured to be hermetically sealed.

The film used for heat-sealing is as thin as several tens of microns, and when the thin films are stacked and heat-sealed while applying pressure, if the pressure applied to the film is insufficient, the film will not melt well. As a result, an unsealed portion is generated, and due to the excessively high pressure applied to the film, there is a possibility that the film is crushed and the sealing portion becomes thin so that the sealing strength is lowered and a sealing failure occurs.

For this reason, various methods are generally used for accurately aligning the space between the vertical seal member and the horizontal seal member, and one example thereof is the adjustment of the clearance between the vertical and horizontal seal rolls. One of the seal rolls forming a pair of seal members is rotatably supported at a predetermined position, and the other seal roll side is supported with respect to one seal roll side together with a bearing member supporting both end sides thereof in the guide frame. The guide bolt is screwed into the guide frame so that it can move forward and backward, and the adjuster bolt that abuts against each bearing member is rotated manually, so that the spring force of the spring that inserts the bearing member of the other seal roll between the rolls. Against or against the spring force of one of the seal rolls while applying a predetermined pressure to the heat seal. Or one of the seal rolls is rotatably provided on the main body side of the packaging device, and the other seal roll side of the seal roll side is provided to the one seal roll side via a guide rod or the like. A roll pressing mechanism that adjusts the pressing force with air pressure is provided, and the clearance between the seal rolls (between the opposing sealing members) is set to a predetermined value via a gap adjusting member according to the thickness and width of the film. By setting the dimensions, by pressing the both ends of the vertical and horizontal seal rolls by the roll pressing mechanism, for example, a single-acting cylinder, the vertical seal portion or the horizontal seal portion is sandwiched between the seal members of the respective seal rolls. Is pressurized and heat-sealed in an appropriate state.

[0006]

By the way, as described above, when heat-sealing the packaging film while respectively filling two kinds of objects to be packaged having different viscosities such as soy sauce and wasabi, the vertical sealing member of the vertical sealing roll is used. A horizontal sealing member for a pair of horizontal sealing rolls is manufactured by bag-forming the packaging film into two rows in a tubular shape, and then individually supplying soy sauce and wasabi into each of the tubular packaging films manufactured in the two rows. Insert the tubular packaging film with
It is pressurized and heated to remove soy sauce consisting of a liquid substance with a relatively low viscosity inside the film and a viscous substance such as wasabi consisting of a semi-solid liquid substance with a high viscosity. The upper and lower portions of the film are respectively melted and then cured to be hermetically sealed.

In this way, particularly when the objects to be packaged having different viscosities are heat-sealed at the same time by the same filling and packaging machine, soy sauce and wasabi, etc. are vertically moved while being pressurized and heated by the horizontal sealing member of the horizontal sealing roll. When heat sealing while handling, when trying to handle the objects to be packaged with different viscosities with the same pressure,
For highly viscous objects to be packed (wasabi), it is necessary to apply a high pressing force to heat seal while extruding the objects to be packed. In some cases, the pressure applied to the packaging film is insufficient and unsealed parts occur on the film. Or, on the contrary, if the same pressure is applied by the horizontal seal roll, the pressure applied to the film when the product is heat-sealed while pushing out the product with relatively low viscosity (soy sauce). Is excessively high, there is a problem in that the film is crushed and the sealing portion becomes thin so that the sealing strength is lowered and other sealing defects occur.

Therefore, according to the present invention, particularly when the objects to be packaged having different viscosities are simultaneously heat-sealed by the same filling and packaging machine, it is possible to favorably perform the gap adjustment (sealing pressure) between the lateral sealing members in an appropriate state. An object of the present invention is to provide a seal pressure adjusting mechanism for a heat seal device in a filling and packaging machine.

The gap dimensions T1 and T2 between the lateral seal members 6B thus formed are filled in a cylindrical packaging bag P having a plurality of rows (two rows in the embodiment) of the articles W to be packaged (soy sauce W1 and wasabi W2). The filling and packaging conditions for the article W to be packaged are set by providing a step D in the width direction corresponding to the positional relationship of the packaging bags P arranged in the two rows according to the filling and packaging conditions. Even if the wrapping objects W (soy sauce W1 and horseradish W2) have different viscosities, by setting the gap dimensions T1 and T2 between the horizontal seal members 6B to predetermined dimensions, the pressing force (seal Pressure) And configured to perform a gap adjusted to be proper state.

As a result, the pair of horizontal seal rolls 6
