Description

  The present invention relates to a method for filling and packaging a moisture-curing sealing material, and more particularly, to a method for filling and packaging a moisture-curing sealing material that facilitates work and enables uniform and packaging without deterioration in quality. is there.

  It is necessary to block moisture in the atmosphere to prevent curing when storing and transporting moisture-curing sealing materials, and various countermeasures such as packaging containers using aluminum laminate sheets have been proposed in the past (for example, Patent Documents 1 and 2).

  However, it is necessary to prevent moisture curing, not only during storage and transportation, but also when the moisture curable sealing material is filled into a container, the moisture curable sealing material may be exposed to the atmosphere. Improvements were needed in the filling and packing method.

  For example, conventionally, when filling a container with a moisture curable sealing material, after the moisture curable sealing material is discharged from a discharge port of a supply device into a bottomed cylindrical container having an inner bag and filled with a predetermined amount The upper surface of the filled moisture-curing sealing material was newly covered with a moisture-proof sheet made of an aluminum laminate sheet or the like. Since this operation is a manual operation by an operator, there is a problem in that the upper surface of the moisture-curing sealing material is exposed to the atmosphere before being coated with the moisture-proof sheet, and the curing progresses to deteriorate the quality.

In addition, since it is a manual work, it is easy for air to enter between the moisture-proof sheet and the top surface of the moisture-curing sealing material, and it is difficult to cover the moisture-proof sheet without air mixing, resulting in variations depending on the skill of the operator. In other words, there is a problem that filling and packaging cannot be performed without uniform and quality deterioration.

  An object of the present invention is to provide a method for filling and packaging a moisture-curing sealant that facilitates work and enables filling and packaging that is uniform and does not deteriorate in quality.

In order to achieve the above object, the moisture-curing sealing material filling and packaging method of the present invention comprises a moisture-curing sealing material discharged from a discharge port of a supply device to a bottomed cylindrical container having a moisture-proof inner bag. In a method for filling and packaging a moisture-curing sealing material for filling and packaging, at least the lower surface of a follower plate having a through-hole penetrating vertically is covered with a moisture-proof sheet provided with a hole at a position corresponding to the through-hole, and the follower plate is covered Attached to the supply device, the penetrating portion and the discharge port are communicated with each other and disposed inside the inner bag, and a moisture-curing sealing material is discharged from the discharge port, and is discharged and filled into the inner bag. A predetermined amount of moisture-curing sealing material is filled while the follower plate is lifted by the moisture-curing sealing material that rises, and the moisture-proof sheet is filled with the follower after filling. Covering the upper surface of the moisture-curable sealant filled as it is removed from the plate, by folding the open end of the inner bag inside a sealed gap between the inner bag and the moistureproof sheet, a hole of the moisture-proof sheet Sealing is performed with a sealing material made of the moisture-curing sealing material, and the sealing material is covered and covered with a patch sheet having moisture resistance.

  According to the method for filling and packaging a moisture curable sealing material of the present invention, moisture that fills and packages a moisture curable sealing material discharged from a discharge port of a supply device into a bottomed cylindrical container having a moisture-proof inner bag. In a method of filling and packaging a curable sealing material, at least the lower surface of a follower plate having a through portion penetrating vertically is covered with a moisture-proof sheet provided with a hole at a position corresponding to the through portion, and the follower plate is attached to a supply device Then, the penetrating part and the discharge port are communicated with each other and placed inside the inner bag, and the moisture-curing sealing material is discharged from the discharge port. Since a predetermined amount of moisture-curing sealing material is filled while raising the follower plate with the material, the upper surface of the moisture-curing sealing material being filled is covered with a moisture-proof sheet and sealed Next, by blocking contact with moisture in the atmosphere it is possible to prevent deterioration in quality.

Also, after the filling, the moisture-proof sheet is removed from the follower plate and covered as it is. by sealing the gap between the bag, the hole in the moistureproof sheet sealed with a sealing material made of the moisture-curable sealant, blocked covered by the patch sheet having a moisture resistance over the sealing material, It is possible to prevent the deterioration of the quality by blocking the contact between the moisture-curing sealing material filled and the moisture in the atmosphere.

  As described above, this filling and packaging operation is easy, and it is possible to perform uniform filling and packaging without any deterioration in quality regardless of the skill of the operator.

  Hereinafter, a method for filling and packaging a moisture-curing sealing material of the present invention will be described based on the embodiment shown in the drawings. FIG. 1 illustrates the first step of the filling and packaging method in a longitudinal section. A moisture-proof inner bag 2 is provided along the inner wall of the bottomed cylindrical container 1, and the opening end 2 a of the inner bag 2 is fixed to the upper end of the bottomed cylindrical container 1 and supplied to the inner bag 2. The moisture-curing sealing material S discharged from the device 7 is filled.

  For example, the inner bag 2 is formed of a film in which a resin film such as polyethylene, polypropylene, nylon, polyester, or the like is laminated on both surfaces of a metal film such as aluminum to ensure moisture resistance. The bottomed cylindrical container 1 is preferably a cylindrical container that facilitates filling and discharging of the moisture-curing sealing material S. For example, a drum can or a similar container can be used.

  The supply device 7 includes a supply pipe 10 whose end is a discharge port 10a, and an attachment 8 fixed around the supply pipe 10 in a flange shape, and the attachment 8 has a mounting hole 9 penetrating in the vertical direction. Is provided.

  The follower plate 3 attached to the attachment 8 has a penetrating portion 4 penetrating vertically at the center, covers the edge from the lower surface to the upper surface with the moisture-proof sheet 6, and the center of the moisture-proof sheet 6 corresponding to the penetrating portion 4. Is provided with a hole 6b.

  The moisture-proof sheet 6 is composed of, for example, a moisture-proof film made of the same material as the inner bag 2 described above. It is sufficient to cover at least the lower surface of the follower plate 3 with the moisture-proof sheet 6. However, as shown in the embodiment, there is an advantage that the moisture-curing sealing material S does not adhere to the follower plate 3 when the edge of the upper surface is covered.

  The follower plate 3 covered with the moisture-proof sheet 6 has the attachment shaft 5 protruding from the upper surface inserted into the attachment hole 9 from the lower surface of the attachment 8 and engaged therewith, and the discharge port 10a of the supply pipe 10 and the penetrating portion 4 are communicated. It is attached and fixed to the attachment 8. With the follower plate 3 attached to the attachment 8, the follower plate 3 is disposed at a predetermined position inside the inner bag 2. The mounting and fixing of the follower plate 3 and the attachment 8 is not limited to the above-described means, and general means can be used.

  FIG. 2 illustrates the second step in a longitudinal section. In this step, the moisture-curing sealing material S is discharged from the discharge port 10a of the supply device 7 into the inner bag 2. The moisture-curing sealing material S that is filled as it is discharged gradually rises inside the inner bag 2, and the lower surface of the follower plate 3 contacts the upper surface of the rising moisture-curing sealing material S via the moisture-proof sheet 6. Both rise and are filled with a predetermined amount of moisture-curing sealing material S. As described above, since the upper surface of the moisture curable sealing material S is covered with the moisture-proof sheet 6 and is in a sealed state, contact with moisture in the atmosphere is blocked and the moisture curable sealing material S is prevented from being cured. Filling becomes possible.

  FIG. 3 illustrates the third step in a longitudinal section. After filling a predetermined amount of moisture-curing sealing material S, the follower plate 3 is removed from the attachment 8, and the moisture-proof sheet 6 is removed from the follower plate 3. Here, since the lower surface of the follower plate 3 is in contact with the upper surface of the moisture-curing sealing material S filled through the moisture-proof sheet 6, the moisture-proof sheet 6 can be directly removed from the follower plate 3. Since the upper surface of the material S is covered, the operation is easy.

  As shown in FIG. 5, the entire upper surface of the moisture-curing sealing material S to be filled is obtained by making the outer peripheral shape F2 of the follower plate 3 substantially the same as the outer peripheral shape F1 of the bottomed cylindrical container 1. Can be pressed by the lower surface of the follower plate 3, and the upper surface of the moisture-curing sealing material S can be easily covered with the moisture-proof sheet 6 without air mixing. Here, the substantially identical shape refers to a shape that allows the follower plate 3 to smoothly move up and down inside the bottomed cylindrical container 1 in consideration of the thickness of the inner bag 2. The lower surface of the follower plate 3 is preferably a planar shape that can easily prevent air from entering.

  Next, the edge portion 6a of the moisture-proof sheet 6 and the opening end portion 2a of the inner bag 2 are folded inward to seal the gap between the moisture-proof sheet 6 and the inner bag 2. At this time, if the sealant bead S1 is interposed between the moisture-proof sheet 6 and the inner bag 2, the moisture entering from the periphery of the gap is absorbed by the sealant bead S1 to improve the sealing performance. As the sealant bead S1, for example, a moisture-curing sealing material S to be filled can be used.

  FIG. 4 illustrates the fourth step in a longitudinal section. In the state of FIG. 3, the moisture-curing sealing material S filled from the central hole 6b of the moisture-proof sheet 6 is exposed and exposed to the atmosphere. Therefore, the central hole portion 6b of the moisture-proof sheet 6 is closed with a moisture-proof patch sheet 11 to prevent the moisture-curing sealing material S from being cured. Here, by making the patch sheet 11 the same material as the inner bag 2 and the moisture-proof sheet 6, it is possible to reduce the cost due to the common use of members.

In the present invention, a small amount of the moisture-curing sealing material S to be filled is prepared separately, and the hole 6b of the moisture-proof sheet 6 is sealed as the sealing material S2, and then the patch sheet is placed on the sealing material S2. close the hole portion 6b covering 11. According to this closing method, moisture entering from the periphery of the hole 6b is absorbed by the sealing material S2, and the internal moisture-curing sealing material S can be prevented from curing.

  The above process is an easy filling and packaging operation as described above, and it is possible to perform filling and packaging without any deterioration in quality, such as curing of the moisture-curing sealing material S, regardless of the skill of the operator.

  In addition, the edge 6a of the moisture-proof sheet 6 and the opening end 2a of the inner bag 2 are folded inward to seal the gap between the moisture-proof sheet 6 and the inner bag 2, and the central hole 6b of the moisture-proof sheet 6 is provided. The operation of closing with the moisture-proof patch sheet 11 may be reversed in the order of execution.
