Description

  The present invention relates to an adhesive application device that applies an adhesive to a metal plate or the like. This adhesive application device is particularly useful when a solid adhesive is used.

  The inventor of the present invention has developed a building material manufacturing apparatus that uses a heat insulating material, a soundproofing material, and the like as a building material by bonding to a metal plate (see Patent Document 1). This is as follows. That is, the frame with the roller attached is provided so that it can move up and down, and the frame with the pin attached is provided so that it can move up and down along the frame, and a pair of pressure rollers are arranged downstream of them. Thus, the building material manufacturing apparatus is configured such that a sheet material coated with an adhesive on one surface is bonded to a metal plate at a predetermined interval while being cut into a predetermined length. The sheet-like metal plate is fed horizontally while feeding a liquid adhesive to the lower surface of the sheet-like heat insulating material or the like, and the adhesive-coated surface is pressed against the metal plate to be bonded. When the predetermined length of heat insulating material or the like has been bonded, the feeding of the metal plate or the heat insulating material is stopped, the heat insulating material or the like is cut, and this time, only the metal plate is sent for the predetermined length. In this way, a predetermined length of heat insulating material or the like is bonded onto the metal plate with a predetermined interval.

No. 52-167282

  The conventional building material manufacturing apparatus has the following drawbacks. Apply an adhesive on the bottom surface of the insulation, etc., and feed the metal plate / insulation material, etc., while the specified length of insulation is adhered to the metal plate, stop the feed of the metal plate / insulation material, etc. and cut the insulation material, etc. Then, the operation of sending only a predetermined length of the metal plate is repeated. A frame with a roller attached is provided so that it can move up and down, and a mounting frame with pins attached can be moved up and down along the frame. The mechanism is complicated and expensive. Moreover, although a liquid adhesive is used, a solvent is used for this. The solvent is harmful to the human body and is not preferable for environmental hygiene.

  The inventor of the present invention thinks that an adhesive application device with a simple mechanism can be obtained if the adhesive is not applied to a heat insulating material or the like, but applied to the side of a metal plate or the like. It was. And I was able to complete the present invention by repeating this and thought / prototype. The problem to be solved by the present invention is to provide an adhesive application device having a simplified mechanism by applying an adhesive to the side of a metal plate or the like. Another object of the present invention is to provide an adhesive application device that is not harmful to the human body by using a solid adhesive instead of a liquid adhesive.

  The adhesive application device according to claim 1 is provided with an adhesive container 14 that is horizontally provided with an adhesive application roller 5 exposed on a part of the surface of the adhesive application roller 5, and the adhesive application roller 5 and the adhesive A gap is provided between the container 14 and a thin screen of the adhesive adhered to the surface of the adhesive application roller 5, and an elevating mechanism that moves up and down at a position directly below the adhesive application roller 5 is provided above the elevating mechanism. Is provided with a lifting roller 2. Any mechanism such as a piston cylinder mechanism or a screw feed mechanism can be employed as the lifting mechanism for moving the lifting roller 2 up and down. An adhesive is put in the adhesive container 14, and a metal plate or the like is placed on the lifting roller 2. The elevating mechanism is operated to raise the elevating roller 2 to bring the metal plate or the like into close contact with the adhesive application roller 5. When the adhesive application roller 5 is rotated, the adhesive in the adhesive container 14 adheres to the surface of the adhesive application roller 5 and is carried and applied onto a metal plate or the like. The elevating roller 2 is lowered when a metal plate or the like is sent for a predetermined length by installing an electronic counter at a predetermined position, and the metal plate or the like is separated from the adhesive coating roller 5. While the adhesive application roller 5 is separated, the adhesive does not adhere to the metal plate or the like. In addition, when the electronic counter counts a predetermined value, the elevating roller 2 is raised again, and the adhesive is applied again. By repeating the above, a product having a certain length of adhesive-applied part and non-applied part is manufactured.

  According to a second aspect of the present invention, the rotational direction of the adhesive application roller 5 in the first aspect of the present invention is the one in which the elevation roller 2 is provided above the elevation mechanism at the position directly below the adhesive application roller 5. It is characterized by being arranged at an interval in the front-rear direction. When only one lifting roller 2 is used, when the thickness of a metal plate or the like to which the adhesive is applied changes, the lifting amount of the lifting roller 2 can only be adjusted. In the case where two lifting rollers 2 are arranged at intervals before and after the rotation direction of the adhesive coating roller 5, if the lifting amount of the lifting roller 2 is slightly larger, the adhesive coating is applied while the metal plate is curved. Since it is in close contact with the attached roller 5, it is not necessary to adjust the lifting amount of the lifting roller 2.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the feeding direction of a metal plate or the like that feeds the lifting roller 2 and the rotation direction of the adhesive coating roller 5 are reversed. Is. If the feeding direction of the metal plate, etc. is the same as the rotation direction of the adhesive application roller 5, the adhesive will not cut immediately after the metal plate etc. is separated from the adhesive application roller 5, and it will be pulled. Sometimes. If the feeding direction of the metal plate or the like and the rotation direction of the adhesive application roller 5 are reversed, the adhesive may be cut off when the metal plate or the like is separated from the adhesive application roller 5. Is less likely to follow.

  According to a fourth aspect of the present invention, in the one according to any one of the first to third aspects, a gap is provided between the surface of the adhesive application roller 5 and the lower part of the adhesive container 14, and the lower part of the gap. The adhesive thickness adjusting piece 13 is attached to the main body via a forward / backward mechanism provided between the main body and the main body. An arbitrary mechanism such as a screw feed mechanism can be adopted as the advance / retreat mechanism of the adhesive thickness adjusting piece 13. By moving the adhesive thickness adjusting piece 13 forward and backward with respect to the adhesive application roller 5, the thickness of the adhesive adhered to the adhesive application roller 5 is adjusted, and the thickness of the adhesive applied to the metal plate or the like is adjusted.

  According to a fifth aspect of the present invention, there is provided the method according to any one of the first to fourth aspects, wherein a porous body such as a punching metal is cut by a linear cutting line that cuts across a plurality of holes. A porous piece 28 is prepared, and the porous piece 28 is attached to a lower position in the adhesive container 14 with a linear cut surface being along the adhesive application roller 5. This is used when the adhesive is not applied to the entire surface but is applied partially in a streak form. Since a porous material such as punching metal is used, it can be realized at a low cost.

  According to a sixth aspect of the present invention, there is provided the heater according to any one of the first to fifth aspects, wherein a solid adhesive is used as an adhesive and a heater 15 for melting the solid adhesive accommodated in the adhesive container 14 is provided. It is characterized by that. The heater 15 may be provided outside or inside the adhesive container 14. When using a solid adhesive, it is not necessary to use harmful solvents. A seventh aspect of the present invention is characterized in that, in the sixth aspect, a heater is incorporated in the adhesive application roller 5. The heater keeps the molten state of the adhesive film adhering to the adhesive application roller 5.

  In the adhesive application device according to the present invention, the adhesive application part and the non-application part each having a predetermined length can be formed on a metal plate or the like by simply raising and lowering the elevating roller 2. This device has a simple structure and can be manufactured at low cost. The work is also simple. According to the second aspect, even if the thickness of the target metal plate or the like is changed, it can be dealt with. According to the third aspect of the present invention, the adhesive hardly pulls back when switching from the adhesive application to the non-application. In the fourth aspect, the thickness of the adhesive applied to the metal plate or the like can be adjusted. According to the fifth aspect, the adhesive can be partially applied in a streak shape. According to the sixth and seventh aspects, since a solid adhesive is used instead of a liquid adhesive, it is harmless to the human body and preferable for environmental hygiene. In the seventh aspect, the molten state of the adhesive film attached to the adhesive application roller 5 is maintained.
