Definitions
- This application relates to a heat sealing device for a bag making machine.
- the present application also relates to a bag making machine provided with the heat sealing device.
- the bag making machine disclosed in Patent Documents 1 and 2 is provided with a heat sealing device that heat seals the components of the bag before molding the bag (cross-cutting process).
- the components of the bag are, for example, a web-shaped body portion and a web-shaped or sheet-shaped gusset portion (side gusset portion, bottom gusset portion, top gusset portion).
- the heat-sealing device heat-seals two web-shaped body parts to each other, or heat-seals a gusset part to the body part.
- the direction of the heat seal is generally the width direction or the length direction of the web-shaped body.
- the direction of the heat seal may be diagonal with respect to the width direction and the length direction of the web-shaped body.
- the gusset portion is heat-sealed to the body portion to form a V-shaped inclined sealing portion.
- Such a heat-sealing device heat-seals the components of the bag by sandwiching the components of the bag between the heated first and second heat-sealing members.
- at least the first heat seal member has a surface that has the shape of the sealed portion to be formed and is pressed against the components of the bag.
- the heat seal device includes at least two urging members that urge the first heat seal member toward the second heat seal member when the components of the bag are sandwiched between the first and second heat seal members. .. At least two urging members are arranged in a horizontal alignment with each other spaced apart from each other. The urging force of the urging member is applied to the components of the bag via the first heat sealing member.
- the urging member is a spring or a cylinder (see Patent Documents 1 and 2).
- the center of the surface of the first heat seal member is on the action line (extending in the vertical direction) of the resultant force of the urging force of the urging member. In such a state, a uniform sealing pressure is applied over the entire surface of the surface, and a high-quality seal can be obtained.
- the first heat seal member is changed to a different shape, or the position of the first heat seal member is changed.
- the center of the figure on the surface of the first heat seal member may deviate from the action line of the resultant force of the urging member.
- the center of the figure deviates from the arrangement line of the urging member. Due to this deviation, the uniform application of the urging force is impaired, and the finish of the sealed portion may be deteriorated.
- the present application provides a heat sealing device capable of adjusting the action line of the total urging force of the urging member in the horizontal direction perpendicular to the arrangement line of the main urging member, and a bag making machine provided with the heat sealing device.
- the purpose is.

- the slider and the first heat seal member are held by the second heat seal member when the component of the bag is sandwiched between the first heat seal member and the second heat seal member.
- At least two main urging members for urging towards the heat seal member Located between the slider and the beam, the slider and the first heat seal member are held by the second heat seal member when the component of the bag is sandwiched between the first heat seal member and the second heat seal member. Equipped with a secondary urging member for urging toward the heat seal member, The at least two main urging members are arranged in a straight line in the first horizontal direction.
- the secondary urging member is arranged offset from the at least two main urging members in the second horizontal direction perpendicular to the first horizontal direction.
- the heat-sealing device is configured so that the urging force of the auxiliary urging member on the first heat-sealing member can be adjusted.
- the auxiliary urging member is the first heat sealing member. It may be configured to be adjustable so that it does not urge.
- the first heat seal member is With the base A seal plate detachably attached to the base may be provided.
- the seal plate may include a protrusion having a surface facing the second heat seal member when the base plate is mounted on the base.
- the heat-sealing device is configured such that a component of the bag is sandwiched between the seal plate and the second heat-sealing member and heat-sealed to form a sealing portion having the shape of the surface of the convex portion. You can do it.

- the surface core pressed against the bag components 11, 12, 13 of the first heat seal member 43 i.e., the actual bag component 11, of the surface 461. It suffices that the center of the part pressed against 12 and 13 (hereinafter referred to as the effective surface of the seal) coincides with the line of action of the resultant force of the urging force of the urging member used for the heat seal (extending in the vertical direction Z). .. As a result, the urging force is evenly applied to the components 11, 12, 13 of the bag through the effective surface of the seal.

This makes it possible to apply a uniform sealing pressure even when the folding amount of the gusset portion 13 is changed. It is possible to prevent deterioration of the quality of the inclined sealing portion 14, thereby preventing problems such as leakage of contents from the inclined sealing portion 14.
- the heat sealing device 4 can adjust the action line of the resultant force of the urging force of the urging member at least in the second horizontal direction Y by adjusting the urging force of the auxiliary urging member 50. Even if the center of the seal effective surface of the first heat seal member 43 deviates from the arrangement line L due to a change in the design of the bag 10, it is possible to apply a uniform seal pressure.
- the edge guideline 463 and the center guideline 464 are formed on the seal plate 46 at a predetermined pitch, for example, by engraving.
- Both guidelines 436 and 464 are formed in a place easily visible to the operator, in the embodiment, on the side surface of the plate portion of the seal plate 46 as shown in FIG. 14A. Both guidelines 436 and 464 may be formed on the surface of the plate portion on the convex portion 460 side.
- the seal plate 46 is a long hole so that the edge 103 and 104 are aligned with the “0” scale of the edge guideline. It is positioned with respect to the base 45 using a known means such as 462. At this time, the drawing core G on the surface of the effective seal is aligned with the "0" scale of the drawing core guideline 464. Then, the action line Lf of only the main urging member 47 is aligned with the “0” scale of the figure core guideline 464.
- the positional relationship between the scale of the edge guideline 463 and the corresponding scale of the center guideline 464 corresponds to the positional relationship between the edge 103, 104 and the center G / G'on the effective seal surface.
- Both guidelines 463,464 are configured. This facilitates the operator to align the line of action Lf'(FIG. 13) with the center G'.
- the heat seal device 4 whose action line can be adjusted is such that the seal plate 46 is repositioned with respect to the base 45, the seal plate 46 is replaced with another seal plate having a convex portion having a different shape, or the seal plate 46 is replaced with another seal plate having a convex portion having a different shape. It can also be used when the position of the center of the seal effective surface is changed as a result of replacing the entire first heat seal member 43 with another one.
- the web 1, and thus the bag components 11, 12, 13 may be made of either a monomaterial material or a composite material as long as it makes heat sealing and bag making feasible.
- the components 11, 12, and 13 of the bag may be a multi-layered film including a base material layer and a sealant layer disclosed in Patent Documents 1-3, respectively.
- the body portions 11 and 12 and the gusset portion 13 are heat-sealed, but other components may be heat-sealed by the heat-sealing device 4.
- the gusset portion 13 is not limited to the bottom gusset portion as in the embodiment, but may be a top gusset portion or a side gusset portion.
- the arrangement of the heat seal device 4 in the bag making machine is not limited to the example of FIG. 1A, and is appropriately determined according to the design of the bag. It can be easily understood by those skilled in the art that the heat sealing device 4 can be applied to various bag making methods in addition to the bag making method of the embodiment.
- the main urging member 47 may be a cylinder, for example, an air cylinder or an electric cylinder, instead of the spring.
- the auxiliary urging member 50 may also be a cylinder, for example, an air cylinder or an electric cylinder, instead of the spring.
- the urging force at the time of heat sealing can be adjusted by adjusting the fluid pressure (air pressure) and stroke. Since the urging force can be calculated from the fluid pressure, the position of the action line Lf'can be adjusted in a shorter time. Further, the urging force of the urging member 47/50 may be detected by the sensor.
- the pressure sensor may be sandwiched between the seal plate 46 and the second heat seal member 44. By using the measurement result of the pressure sensor, it is possible to confirm whether or not the action line Lf'passes the center G'.
- the heat sealing device 4 or the bag making machine may further include a user interface such as an operation panel composed of a touch panel type display.
- the heat sealing device 4 or the bag making machine may be configured so that the urging force of the main urging member 47 and the sub urging member 50 can be increased or decreased in response to the operation of the user interface by the operator. This can be easily done with an electric cylinder.
- the urging force of the electric cylinders 47 and 50 may be controlled by a value calculated using software. Next, it may be confirmed by using the pressure sensor that the action line Lf'actually passes through the figure core G'. Further, fine adjustments may be made by manipulating the user interface.
- three or more main urging members 47 may be arranged in a straight line.
- One or three or more auxiliary urging members 50 may be arranged offset from the arrangement line L1 in the second horizontal direction Y.
