Description

  The present invention relates to a coating apparatus that applies a liquid adhesive to a downward surface such as a ceiling.

  A conventional general adhesive application device is intended for an upward adhesive application surface. In other words, the liquid adhesive container has an opening that allows the amount of the adhesive to flow out by gravity when the opening is directed downward to some extent, and the user spreads the discharged adhesive on the application surface. Yes. In order to make the operation of spreading the coating more convenient, there is a configuration in which rollers and brushes are provided. However, if these are applied to a downward adhesive application surface, for example, a ceiling surface, since the opening through which the adhesive comes out faces upward, the adhesive does not necessarily come out continuously. . For this reason, when applying an adhesive to the ceiling surface, etc., use an adhesive container made of a flexible material, press the container from the outer surface to extrude the adhesive, and apply an appropriate amount. It is applied to the ceiling surface and spread.

As a thing which seems to be able to apply | coat a liquid adhesive to such a downward adhesive application surface, there exists a container of the glue etc. of patent document 1, for example. The general configuration is that an application roller is provided by being exposed from the opening of a cylindrical container having one end open, and a transmission disk is pressed against the application roller so that it can rotate integrally. A worm wheel provided at one end of the screw rod provided in the axial direction in the cylindrical container is meshed with a worm provided coaxially with the transmission disk, and screwed into the screw rod and the inside of the cylindrical container. By providing an extrusion plate that moves in the cylindrical container by guidance by an axial guide protrusion provided on the peripheral surface, and by pressing and rotating the coating roller onto the coated surface, a transmission disk and a worm gear The extruding plate is moved through a screw rod to forcibly supply fluid glue or the like filled in the cylindrical container to the coating roller side. That is, extrusion is performed by the piston action of the extrusion plate.
Japanese Patent Application Laid-Open No. 2004-243591

In order to apply the liquid adhesive to the adhesive application surface facing downward like the lower surface of the ceiling, it is necessary to push up the adhesive against gravity and take it out of the container. Therefore, the adhesive application device is flexible. The configuration is such that the operator uses an adhesive container to push or the pusher plate that moves in conjunction with the rotation of the coating roller as in the technique described in Patent Document 1 is pushed out. However, the former has a problem that it is very difficult to keep the amount of the adhesive to be extruded constant, and it is difficult to extrude when the amount of the adhesive in the container becomes small. Therefore, a constant amount of adhesive is forcibly extruded onto the roller portion and spreads the extruded adhesive, but there is a problem that it is difficult to produce an optimal extrusion amount. If the amount of extrusion of the adhesive is large, it may be spread, but not all of the adhesive that is extruded on the ceiling surface will adhere, so it may fall and hit the operator, and when the amount of extrusion is small Will be used to repaint. In any case, since an appropriate amount of adhesive is difficult to be applied to the ceiling surface or the like, the adhesive application operation is difficult to be performed smoothly. Therefore, in the configuration in which the adhesive is extruded, it is difficult for the operator to use the coating apparatus, and smearing of the adhesive is likely to occur, and the workability is not good. In addition, the latter has a problem that the manufacturing cost increases because the configuration is considerably complicated.
An object of the present invention is to provide an easy-to-use adhesive applicator that is less likely to cause smearing in the adhesive application operation on the downward surface without depending on the configuration in which the adhesive is extruded from the container.

  The adhesive applicator of the present invention has a belt tensioning structure in which an endless belt for holding an adhesive capable of holding a liquid adhesive in an impregnated state is stretched so that it can run. The lower end portion of the belt extending structure reaches the bottom in the adhesive container, and the upper end portion penetrates the lid portion and the pulley portion and its pulley A portion of the endless belt passing through the outer periphery is exposed to the outside so as to protrude upward.

  In this configuration, when a lid-like part is attached to an adhesive container containing a liquid adhesive, the part of the belt tensioning structure installed on the lid-like part and the part of the endless belt are immersed in the adhesive. . In this state, when the endless belt portion engaged with the pulley protruding upward is pressed against the adhesive application surface such as the lower surface of the ceiling and moved in a predetermined direction in which the endless belt travels, the endless belt travels and The pulley rotates. As a result, the portion of the endless belt immersed in the adhesive comes out of the container in a state of being impregnated with the adhesive. When the pressing and movement are further continued, the adhesive is continuously applied to the adhesive application surface according to the movement length with the width of the endless belt.

  It is preferable that the endless belt has an outer peripheral surface made of a sponge-like porous material. In this configuration, the sponge-like porous material on the outer peripheral surface of the belt pushes out the liquid adhesive impregnated in the portion sandwiched between the pulley and the application surface, so that the thickness of the sponge-like layer is increased. When an appropriate amount is determined, an appropriate amount of adhesive is always applied to the application surface.

  It is preferable that the outer peripheral surface of the pulley exposed to the outside and the inner peripheral surface of the endless belt are provided with non-slip irregularities. In this configuration, since the endless belt always rolls together with the pulley when the pulley rolls, the adhesive is reliably supplied to the application surface and the amount thereof is also constant.

  It is preferable that the pulley exposed to the outside is provided with a non-slip convex portion for forced rolling protruding radially outward at both outer peripheral portions of the endless belt engagement position. In this configuration, the pulley is used in a state where the non-slip convex portion is in contact with the application surface, and the pulley is reliably rotated. Therefore, both the endless belts are easy to rotate, and the adhesive is evenly applied.

  The belt tension structure may be configured to be detachable from the lid-shaped portion. In this configuration, when a failure occurs in the pulley or the endless belt during use, the work can be continued by replacing the belt tensioning structure with another one.

In the invention according to claim 1, the endless belt portion immersed in the adhesive successively comes out continuously at the upper part of the adhesive container, and in particular, without performing the operation of extruding the adhesive from the adhesive container. It can be applied and provides an easy-to-use effect.
The invention described in claim 2 has an effect that an appropriate amount of adhesive is always applied to the application surface.
The invention according to claim 3 has an effect that the adhesive is reliably supplied to the application surface and the amount thereof is also constant.
The invention according to claim 4 has an effect that the adhesive is uniformly applied.
According to the fifth aspect of the present invention, when a problem occurs in the pulley or the endless belt during use, the belt tensioning structure can be replaced with a good one and the operation can be continued.

  A belt tensioning structure in which an endless belt for holding an adhesive that can hold a liquid adhesive in an impregnated state is stretched so as to be able to run is installed on a lid-like portion provided at the upper end opening of the adhesive container. The lower end portion of the belt tensioning structure reaches near the bottom in the adhesive container, and the upper end portion penetrates the lid-like portion and the pulley portion and the endless belt portion passing through the outer periphery of the pulley. It is exposed to the outside so that it protrudes upward. The outer peripheral surface of the endless belt is made of a sponge-like porous material. Non-slip irregularities are provided on the outer peripheral surface of the pulley exposed to the outside and the inner peripheral surface of the endless belt. A non-slip convex portion for forced rolling projecting outward in the radial direction is provided on an outer peripheral portion on both sides of the endless belt engaging position of the pulley exposed to the outside. And the said belt extension structure is comprised so that attachment or detachment with respect to the said lid-shaped part is possible.

  A position example of the present invention will be described with reference to FIGS. The adhesive application device 1 includes a belt tension structure 2, an endless belt 3, an adhesive container 4, a lid-like portion 5, and the like.

  As shown in FIGS. 2A and 2B, the belt extending structure 2 is positioned so that two elongated plate-like portions 10 are parallel to each other in a face-to-face state and have a predetermined distance via the support portion 11. The upper pulley 12 and the lower pulley 13 are rotatably supported between the plate-like portions 10 at both ends. A protrusion at one end of the plate-like portion 10 shown in the figure is a stopper 14. The upper pulley 12 at the upper end has a belt groove 15 on the outer periphery, and both side walls of the groove are side walls 16 whose height is sufficiently smaller than the thickness of the endless belt 3 to be described later, and is enlarged in FIG. As shown in the figure, a large number of tapered projections 17 are projected along the outer periphery of the side wall 16 as slip preventing projections for forced rolling, and when the belt is hung, about half of the belt thickness is small projections 17. It protrudes from the tip. In the drawing, 18 is a pulley shaft, and 19 is a shaft hole. Each portion constituting the belt tension structure 2 is formed of a plastic material to which an adhesive is difficult to adhere. An endless belt 3 is stretched between the upper pulley 12 and the lower pulley 13 of the belt stretching structure 2. The lower pulley 13 at the lower end may be a pulley without the tapered protrusion 17 or without the belt groove 15.

  The endless belt 3 is formed as a thin tensile layer 20 made of a flexible material having a relatively high strength, for example, rubberized cloth, plastic, or the like, on the inner peripheral surface portion that contacts the groove bottom of the upper pulley 12. A thick sponge layer is formed on the liquid adhesive impregnation layer 21. The surface where the tensile layer 20 and the groove bottom of the upper pulley 12 are in contact with each other is provided with non-slip irregularities, for example, simple teeth (not shown) that mesh with each other such as a timing belt and its pulley. Good.

  As shown in FIG. 2A, the adhesive container 4 is a substantially cylindrical rigid container large enough to be gripped with one hand, and is screwed into the opening 22 having a slightly smaller diameter at the upper end. The shaped part 5 is mounted. This lid-like portion 5 is provided with a mounting opening 23 having a rectangular cross section to be mounted by inserting a belt extending structure 2 penetrating the ceiling wall vertically into a normal screw lid, and extends the mounting opening 23 up and down. Thus, a rectangular tube-shaped guide portion 24 is formed. The mounting opening 23 is of a size that allows the belt tensioning structure 2 to which the endless belt 3 is mounted to be inserted. The belt extending structure 2 is inserted with the stopper 14 facing upward, and when the stopper 14 comes into contact with the upper end of the guide portion 24, it cannot be pushed any further. In this state, the lower end of the belt tensioning structure 2 reaches near the bottom of the adhesive container 4.

  The adhesive applicator 1 configured as described above is used by storing the liquid adhesive 25 in the adhesive container 4. The use is as follows. When the adhesive container 4 is gripped with one hand and the outer surface of the upper pulley 12, that is, the tapered protrusion 17 is pressed against the ceiling surface 26 that is the application surface and rolled, the adhesive of the endless belt 3 is initially used. The portion not impregnated with the abutment contacts the ceiling surface 26, but the portion immersed in the adhesive by the running of the endless belt 3 comes to the outer peripheral position of the upper pulley 12. When the pulley is further rolled, the adhesive held in the impregnation layer 21 of the endless belt 3 is sent out from the impregnation layer 21 by the endless belt 3 being sandwiched between the ceiling surface 26 and the groove bottom of the upper pulley 12, Adhere to the ceiling. At this time, the upper pulley 12 rolls without sliding on the ceiling surface 26 due to the presence of the tapered small protrusions 17, and the degree of compression of the endless belt 3 is kept constant, and the endless belt 3 meshes with the upper pulley 12 with teeth and does not slip. To the upper pulley 12 at the same rotational speed. Therefore, the sponge on the outer peripheral surface of the endless belt 3 is in a state of rolling with the ceiling surface 26 without slipping, and a surface on which the adhesive is applied very uniformly and well is obtained in a straight line with the width of the endless belt 3. Since the endless belt 3 is immersed in the adhesive 25 and the adhesive is continuously supplied to the upper pulley 12 side in a state where the sponge portion is impregnated, the supply of the endless belt 3 is performed by the liquid level of the adhesive 25 on the endless belt 3. There is no break until it does not touch the bottom. That is, it can be used up without difficulty until the adhesive in the adhesive container 4 is almost empty.

  According to this adhesive application device 1, when applying the adhesive to the ceiling surface, there is no need to perform an operation of extruding the adhesive from the adhesive container, it can be applied continuously and with good workability, The construction is also made of a belt tensioning structure that can be formed of plastic or a simple endless belt, so that the manufacturing cost can be kept low.

  The teeth with which the upper pulley 12 and the endless belt 3 mesh, and the small protrusions 17 of the upper pulley 12 may be omitted. Further, the lower pulley 13 may be a fixed member (made of fluororesin) having good sliding property.

  In interior work such as a ceiling surface of a building, it is used for an adhesive application work, so that the work efficiency can be improved and a good adhesion work can be performed.
