Description

  TECHNICAL FIELD The present invention relates to a spatula for handling a sealing agent, and particularly for handling a sealing agent suitable for performing sealing work on a joint of an outer panel and an inner panel of a vehicle member at an individual level. Regarding the spatula.

  In general, a door of a vehicle such as an automobile, a hood, a luggage compartment door, a back door, a side door, a trunk lid, and the like are made by overlapping two plate members of an outer panel and an inner panel. Since both are usually joined by folding the edge of the outer panel toward the inner panel, a joint (note: also referred to as a hemming part) with the outer panel is formed around the edge of the inner panel. And it is common to seal with an elastic material from this joined part. In the automobile manufacturing process, a sealing agent is applied from above the joint with a sealing agent application robot apparatus using a room temperature curable sealing agent and dried to dry (for example, Patent Document 1).

  The reason for sealing the joint with an elastic material is as follows. First, if the joint is exposed, there is a design problem that it simply looks bad. Next, since the metal edge of the outer panel is exposed at the joint, there is a risk of injury if a finger or arm touches the joint by mistake. Furthermore, if water or dust enters from the gap between the inner panel and the outer panel at the joint, there is a risk of deterioration due to rust or dirt on the metal inner panel or outer panel.

  By the way, when a car door or the like is greatly damaged due to a vehicle accident or the like, it may be necessary to order parts such as a replacement door from a car manufacturer. However, when only parts such as doors are ordered for replacement, some manufacturers may be provided with parts that are not sealed at the joint. In addition, even if it is not necessary to replace the parts, there are cases where the joint is deformed when sealing is performed by sheet metal repair, and sealing must be performed again. In such a case, it is necessary to perform a sealing operation on the joint at the individual level.

  However, at an individual level that does not have a specialized machine such as the above-described sealing agent application robot apparatus, the sealing work cannot be performed in the same manner as in the manufacturing factory. Therefore, the following method is adopted. First, a curing tape is affixed at a predetermined height on both sides of the joint. Next, a sealing agent is applied from above the joint. Then, before the applied sealing agent is solidified, the excess sealing agent is scraped off so that the surface of the sealing agent (hereinafter also referred to as the sealing surface) is smoothed with a spatula. Finally, after the sealing agent is solidified, the curing tape is peeled off from both sides of the sealing surface to form a predetermined height of sealing on the joint.

  However, in this method, since the process of applying the curing tape, which is an essential process, is complicated, the burden on the operator is large. Furthermore, when the sealing agent protrudes and is also applied onto the curing tape, unnecessary sealing may occur at the edge of the sealing surface on the curing tape when the curing tape is peeled off. In such a state, the appearance of the sealing surface is deteriorated, and the above design problem cannot be solved.

  Therefore, in Patent Document 2, sealant extrusion is performed so that even an unskilled person can apply a sealing agent accurately and easily and can be provided at low cost without the need for a separate tool. A nozzle body that is attached to the discharge port of the container, and an elastic member that is provided on at least the surface facing the sealant application surface of the nozzle body, and that contacts the application surface during sealant application. Disclosed is a technology for a sealant extrusion container nozzle that has a friction coefficient with a coating surface that is larger than a friction coefficient between the nozzle body and the coating surface. According to this technique, an elastic member having a high friction coefficient is provided on at least the surface of the nozzle body that faces the sealant application surface, so that a grip force is applied between the application surface and the nozzle during the sealant application operation. As a result, the nozzle becomes difficult to slide, and as a result, the coating operation can be performed very stably, and even an unskilled person can perform the coating operation accurately and easily. In addition, it is economical because it is not necessary to prepare a jig and tool separately.

  Certainly, if such a nozzle for a sealant extrusion container is used, a sealing agent application operation can be performed stably along the joint portion even if it is not an expert. However, this technique does not constantly discharge a certain amount of the sealing agent to be applied, nor does it assist the operator to move the sealing agent container at a constant speed. However, there is a problem in that a sealing is formed in which unevenness occurs in the height or a thick portion occurs depending on the amount of application.

  In order to eliminate such a complicated sealing operation, there is a cord-like sealing tape in which a double-sided tape is provided on the back surface (for example, Patent Document 3). If a cord-like sealing is used, a good-looking seal can be formed by a simple operation of sticking a cord-like sealing tape along the joint using a double-sided tape.

  However, in such a method using a sealing tape, a double-sided tape is used, so that a gap corresponding to the double-sided tape is formed between the sealing tape and the joint. Since water or the like can sufficiently enter from the gap, there is a risk of deterioration due to rust or dirt on the metal inner panel or outer panel. In addition, there is an economic problem that commercially available sealing tape is expensive.

JP-A-6-79231 JP 2009-195859 A Japanese Patent Laid-Open No. 9-273630

  Therefore, the problem to be solved by the present invention is the above-mentioned property required for sealing the joint, that is, the design is good, and it prevents the fingers and arms from being injured when touched, and prevents the deterioration of the inner panel and the outer panel. It is an object to provide a spatula for handling a sealing agent so that a sealing operation having the above can be easily achieved even at an individual level.

  In order to solve the above-mentioned problem, a thick plate including a front part including a front face in the longitudinal direction and a rear face in the longitudinal rear direction, wherein both ends of the front face and the back face are respectively connected by side faces extending in the vertical direction. In a spatula for handling a sealing agent having a shape and elasticity, in the present invention, any one of the lateral edges of the front portion has a rectangular notch, and the notch has a flat guide surface extending in the lateral direction, The front portion includes a tapered surface extending in the lateral direction while reducing the thickness from any part of the front portion toward the handling surface, and the handling surface includes: It is a flat surface or curved surface having a length in the longitudinal direction of 5 to 25 mm, and the handling surface is provided with a recess for sealing formation, and the recess for sealing formation extends in the same shape in the thickness direction, and its center position is , The handling surface From intersections of the guide surface toward the longitudinal direction forwardly and most important features to be arranged at a position of 3 to 15 mm.

  According to the spatula for handling the sealing agent of the present invention, when the guide surface is placed along the folded edge of the outer panel such as a door, the sealing surface is formed so that the concave portion for forming the sealing surface of the handle comes on the joint. And because the shape is the same as the seal that was affixed at the time of the new car, if you remove the excess sealant by handling the sealant applied on the joint with the spatula handling spatula of the present invention, Even if it is not a person, it can leave the sealing agent of the shape which does not produce an unevenness | corrugation and a protrusion on a sealing surface, and is very good-looking. Furthermore, not only the appearance but also the handling work is performed on this sealing agent, so that it is possible to achieve a sealing with high adhesion to the joint. As a result, the properties required for sealing the joints, that is, good design without causing irregularities and protrusions on the sealing surface as in the past, good for preventing injury of fingers and arms when touched. Thus, sealing having a function of preventing the deterioration of the inner panel and the outer panel can be easily achieved even at an individual level work.

  Further, according to the spatula for handling the sealing agent of the present invention, the front portion includes a tapered tapered surface extending in the vertical direction while reducing the thickness from any portion of the front portion toward the handling surface, The handling surface of the notch is a flat surface or a curved surface and is not sharp. Therefore, the contact area between the handling surface and the joint can be increased, and the handling surface can be firmly brought into contact with the joint. Therefore, when the sealing agent is handled on the handling surface, it is possible to prevent the weight and viscosity of the sealing agent from escaping from places other than the recess for forming the sealing, and the height of the sealing surface can be adjusted smoothly. it can.

  In addition, according to the spatula handling spatula of the present invention, the front part has a tapered shape with a tapered surface, so that when the sealing agent is handled by the notch handling surface, the notch handling surface is joined. When abutting on the portion, the handling surface can be made to follow the shape of the joint portion with the minimum necessary force without applying extra force.

  Hereinafter, the present invention will be described with reference to the drawings. However, the present invention is not limited to the mode shown in the drawings. In FIG. 1 and FIG. 5, for convenience of explanation, the XYZ three-dimensional coordinate system is defined with the thickness direction of the sealing agent handling spatula 100 as X, the vertical direction as Y, and the horizontal direction as Z.

(Outline of spatula for handling sealant)
The spatula handling spatula 100 of the present invention is a spatula having a front plate 110, a back surface 120, and a side surface 130 and having a thick plate shape and elasticity. The outline of the spatula 100 for handling the sealing agent of the present invention is shown in FIGS. The sealing agent handling spatula 100 referred to in the present invention is a spatula for use in sealing work performed at an individual level. For example, in an automobile door, a hood hood, a luggage compartment door, a back door, a side door, a trunk lid, and the like, a joining portion 400 formed when two plate members of an outer panel and an inner panel are overlapped with each other. It is a carpenter's tool for scraping off the excess sealing agent so as to level the sealing surface before the sealing agent is solidified.

  An elastic material such as rubber or elastomer can be used as the material for the spatula 100 for handling the sealing agent. Specifically, acrylic rubber, isoprene rubber, urethane rubber, chlorinated polyethylene rubber, epichlorohydrin rubber, ethylene-propylene rubber, chloroprene rubber, silicon rubber, hydrogenated nitrile rubber, styrene butadiene rubber, natural rubber, nitrile rubber, fluorine Rubber, butyl rubber, polybutadiene rubber or the like can be used. Further, instead of the rubber, acrylic resin, polyester resin, urethane resin, vinyl chloride resin, polypropylene, polycarbonate, PET resin, fluororesin, polyethylene, AS resin, ABS resin, polystyrene resin, polyvinyl chloride, polyvinylidene chloride, Examples thereof include thermoplastic resins such as polyvinyl acetate, nylon, alkyd resins, phenol resins, epoxy resins, and polyphenylene sulfide resins.

(Front part)
The front part 110 referred to in the present invention is a part including the front (XZ plane) 111 in the longitudinal direction (Y direction) among the parts of the sealer handling spatula 100, and the sealant handling spatula 100. In the YZ plane, a region located in the longitudinal direction forward of the Z direction virtual extension line of the guide surface 150 (virtual line I indicated by a broken line in FIG. 1).

(Notch)
The spatula 100 for handling a sealing agent according to the present invention has a notch in which one of the edges of the front portion 110 in the lateral direction is rectangular. The notch is formed by a flat guide surface 150 (XZ plane) extending in the horizontal direction and a handling surface 160 (XY plane) extending in the vertical direction. 1 to 5 show a state in which a notch is provided only on the left side of the front part 110 drawing.

(Handling surface)
The handling surface 160 is a flat surface or a curved surface having a longitudinal length of 5 to 25 mm, and the handling surface 160 can be a curved surface by, for example, C surface processing or R surface processing. C-plane machining refers to machining that creates a C-plane by scraping off the corners. The C plane refers to a plane made at a portion called a corner or an edge. The processing for making the handling surface 160 a curved surface can be R-surface processing. R surface processing refers to processing for making the corners of the substrate R (= radius), that is, processing for making the corners round. The handling surface 160 needs to have a length in the vertical direction that is equal to or longer than the distance from the folded edge of the outer panel to the joint portion 400. Although there are some differences depending on the vehicle type and location, if the length of the handling surface 160 in the vertical direction is 5 to 25 mm, it is possible to handle almost all vehicle types and locations.

  In the spatula 100 for handling a sealing agent according to the present invention, the handling surface 160 is flat or curved and not sharp, so that the contact area between the handling surface 160 and the joint can be increased. In addition to being able to be firmly brought into contact with the handle surface 160, when the sealant is handled on the handling surface 160, the weight and viscosity of the sealant escape from between the handle surface 160 and the joint. Since it can be prevented, the height of the sealing surface can be adjusted smoothly. The thickness W1 (see FIG. 2) of the handling surface 160 is preferably in the dimensional range of 0.5 to 1.5 mm.

(Recesses for forming sealing on the handling surface)
The handling surface 160 is provided with a recess 161 for sealing formation. This is because when the sealing agent before drying applied on the joint 400 is handled along the joint 400 with the sealing agent handling spatula 100 of the present invention, excess sealing agent is removed and the sealing surface is removed. This is a dent for leaving a good-looking sealing agent with a uniform height. Therefore, the concave portion 161 for forming the sealing needs to extend in the same shape in the thickness direction, and when the center of the concave portion 161 is aligned with the folded edge of the outer panel of the door or the like, It is necessary to arrange so that it may become 400 or more. Although the distance from the folded edge of the outer panel of the door or the like to the joint 400 varies slightly depending on the vehicle type and location, the center position of the concave portion 161 for sealing formation is the intersection of the handling surface 160 and the guide surface 150. If it is 3 to 15 mm (corresponding to L in FIG. 1) from the portion (corresponding to point P in FIG. 1) in the longitudinal direction, it is possible to cope with almost all vehicle types and parts.

  It is preferable that the shape of the concave portion 161 for forming the seal corresponds to the shape of the sealing that has been pasted on the original. Since the sealing used for the joint portion 400 such as a door is often a semicircular (kamaboko-shaped) having a diameter of 3 to 10 mm, the shape of the concave portion 161 for forming the sealing is also as shown in FIGS. In addition, it is preferable to have a semicircular shape with a diameter of 3 to 10 mm. On the other hand, a rectangular seal with a length of 3 to 15 mm and a width of 1 to 5 mm is sometimes used for sealing gaps such as joints and joints on the rear fender. The shape of the recess 161 is also preferably a rectangular shape having a length of 3 to 15 mm and a width of 1 to 5 mm (not shown).

(Tapered surface)
The front portion 110 includes a tapered surface 112 extending in the lateral direction (Z direction) while reducing the thickness from any portion of the front portion 110 (the taper start position of 113 in FIG. 1) toward the handling surface 160. That is, the front part 110 is tapered from the taper start position 113 toward the handling surface 160. This is because the height of the sealing surface can be adjusted more smoothly by damming the sealing agent with the tapered surface 112 when handling the sealing agent with the notch handling surface 160. . Further, when the sealing agent is handled by the notch handling surface 160, when the notch handling surface 160 is brought into contact with the joining portion 400, the handling surface is joined with the minimum necessary force without applying extra force. It is because it can be made to follow the shape of a part. In order to ensure such workability sufficiently, the inclination angle θ (see FIG. 3) with respect to the lateral direction of the tapered surface 112 (broken line J in FIG. 3) may be within an angle range of 5 to 30 °. preferable.

(back)
The back surface 120 is the XZ surface on the rear side in the longitudinal direction in the portion 100 of the spatula 100 for handling the sealing agent.

(side)
The side surfaces 130 and 140 are XY surfaces that extend in the vertical direction (Y direction) and connect both the front surface 111 and both ends of the back surface 120 of the sealant handling spatula 100. Hereinafter, the left side surface 130 in FIG. 1 is referred to as the left side surface 130, and the right side surface 140 in FIG. 1 is referred to as the right side surface 140.

  The back surface 120 and the side surface 140 on the opposite side of the side surface 130 having the handling surface 160 are locations that become a handle in the sealing agent handling operation using the handling surface 160. As shown in FIGS. 1 to 5, the back surface 120 and the side surfaces 130 and 140 may be provided with a taper that tapers toward the edge side. Providing such a taper makes it easier to hold the spatula handling spatula 100 when handling the sealing agent.

(Recesses for sealing other than the handling surface)
In the sealing agent handling spatula 100 of the present invention, a sealing forming recess different from the sealing forming recess 161 of the handling surface 160 is formed at one of the side surfaces 130 and 140 so as to extend in the thickness direction. Also good. The recess for forming the sealing may be provided on either the right side surface 130 or the left side surface 140. However, when a notch is provided only on the left edge as shown in FIG. 1, the side opposite to the notch is provided. It is preferable to provide a sealing-forming recess 141 at any position on the left side surface 140 of the lens. Moreover, you may form the recessed part 121 for sealing formation different from the recessed part 161 or the recessed part 141 in any position of the back surface 120 so that it may extend in the thickness direction.

  It is preferable that the shapes of the recesses 121 and 141 for forming the seals other than the recesses 161 on the handling surface correspond to the shape of the seal attached on the original. That is, a semicircular shape with a diameter of 3 to 10 mm, or a rectangular shape with a length of 3 to 15 mm and a width of 1 to 5 mm is preferable. In the case where two or more sealing formation recesses other than the sealing formation recess 161 provided on the handling surface 160 are provided at any one of the side surfaces 130 and 140 and the back surface 120, the sealing formation recess 161 is provided at the second and subsequent locations. It is preferable to use a different shape. The embodiment shown in FIGS. 1 to 5 shows a case where the sealing formation recess 121 is rectangular and the sealing formation recess 141 is semicircular. Therefore, in the concave portion 121 for sealing formation, it is preferable that the length W2 is 3 to 15 mm and the width D is 1 to 5 mm (see FIG. 1).

(how to use)
FIG. 5 shows a scene of the sealing operation using the spatula handling spatula of the present invention. Examples of the sealing operation for the joint using the sealing agent handling spatula 100 of the present invention include the following methods [A] and [B].

[A] Method of Directly Applying Sealing Agent to Joint Portion In this method, first, a sealing surface is formed on the joint portion 400 by applying an appropriate amount of sealing agent along the joint portion. The sealing surface at this time may not be slightly along the joint, and the sealing surface may be somewhat uneven. Next, before the sealant is dried and solidified, the center of the seal-forming recess 161 formed on the handling surface 160 is positioned on the center line of the joint using the sealer handling spatula 100 of the present invention. Then, the sealing surface is handled by the handling surface 160. At this time, according to the present invention, when the guide surface 150 is arranged so as to contact the edge of the outer panel, it is designed to naturally be in the position as described above. 161 can handle the sealing surface. By handling the sealing surface in this manner, the sealing agent can be in close contact with the joint portion 400 and the excess sealing agent can be scraped off, so that the sealing surface formed with the remaining sealing agent is improved in appearance. If this is left for several hours to several days, the sealing agent solidifies in the same shape and the sealing is completed.

[B] A method of separately preparing a linear sealing material and sticking it to a joint using a sealing agent. In this method, first, a sealing agent is applied linearly on a metal or glass plate having a smooth surface. To do. At this time, the sealing agent is applied on a straight line while being discharged along the edge of the plate at a distance corresponding to L in FIG. 1 from the edge of the plate, thereby forming a line of the sealing agent. Next, before the sealing agent is solidified, the center of the concave portion 161 for forming the sealing agent formed on the handling surface 160 of the spatula for handling the sealing agent 100 is positioned on the center line of the joint portion of the previously prepared sealing agent. The sealing surface is handled by the handling surface 160. In this method, unlike the case of handling on a three-dimensionally curved joint according to the shape of a vehicle door or the like, the streaks of the sealing agent formed on a smooth plane are handled linearly. Even a general worker who is not an expert can easily form a sealant having a good appearance. If this is left for several hours to several days, the sealing agent solidifies in the shape as it is to form a linear sealing material, and therefore the linear sealing material is peeled off from the top of the plate.

  Next, a small amount of a sealing agent is applied along the joint 400. Since this sealing agent is used for the adhesive action between the linear sealing material and the joint portion 400, it is applied in a smaller amount than in the case [A]. It arrange | positions so that the said linear sealing material may be along from it. The sealing agent-treating spatula 100 was set so that the center of the sealing-forming recess 161 formed on the handling surface 160 of the sealing agent handling spatula 100 was located on the center line of the linear sealing material, and the handling surface 160 Handles linear sealing materials. At this time, when the guide surface 150 is arranged so as to come into contact with the edge of the outer panel, it is designed so that the guide surface 150 is naturally positioned as described above. It can handle linear sealant. By treating the linear sealing material thus created with good appearance, the linear sealing material is brought into close contact with the joint through the sealing agent used for adhesion. At this time, since the sealing agent and the linear sealing material used for adhesion are only different in the liquid state or solidified state of the same compound, the adhesion between them is very high. Adhesiveness with the joining part 400 which is not inferior to [A] can be secured.

(Sealing agent)
The sealing agent used in the sealing operation to the joint using the spatula for handling the sealing agent 100 of the present invention can be used without particular limitation, but as a general sealing agent, a one-component curable modified polyurethane And modified silicone-based sealing agents. Since the sealing to the vehicle body is usually applied to the interior color in the vehicle in order to make it inconspicuous, a one-component curable modified polyurethane sealing agent that is easy to apply is generally used.

  Hereinafter, the present invention will be described in detail by way of examples. However, in order to clarify the comparison of the finished seals, the test was conducted on a smooth and flat steel plate, not on the joint of the vehicle.

(Example)
Sealing work was performed on the joint 400 using the sealing agent handling spatula 100 in the manner shown in FIG. Acrylic rubber was used as the material of the spatula 100 for handling the sealing agent. The handling surface 160 was subjected to C-plane processing with the surface as a flat surface, and the thickness W1 of the handling surface 160 was 1.00 [mm]. The inclination angle θ with respect to the lateral direction of the tapered surface 112 was set to 16 [°]. The length L (see FIG. 1) from the intersection of the handling surface 160 and the guide surface 150 to the sealing formation recess 161 was 7.50 [mm]. The shape of the concave part 161 for sealing formation was semicircular, and the dimension of the radius R was 1.50 [mm]. This sealing agent handling spatula 100 is a spatula of the embodiment.

  A trade name “urethane body sealer cartridge 8651” (manufactured by Sumitomo 3M Limited) was applied along the joint 400 as a modified polyurethane sealant. In the applied state, the coating mark (sealing surface) of the sealing agent was slightly curved or uneven in height. Next, using the spatula of the embodiment, the notch guide surface 150 is brought into contact with the fold of the outer panel 200 and the handling agent 160 is brought into contact with the joint 400, and the spatula 100 for handling the sealing agent is used. Sealing work was performed by handling the sealing agent along the joint 400 with the handling surface 160. The result is shown in FIG. As shown in FIG. 6, in the sealing using the sealing agent handling spatula 100 of the present invention, the height of the sealing surface could be aligned to a semicircular shape with a radius of 1.50 [mm]. Further, the unevenness of the height, the variation of the sealing width, and the protruding of the sealing edge did not occur on the sealing surface.

(Comparative example)
At the tip of the product name “urethane body sealer cartridge 8651” (manufactured by Sumitomo 3M Limited), which is a modified polyurethane-based sealant, a sealing agent filling nozzle “fitting nozzle FT-10” (manufactured by Big Tool Co., Ltd.) It was mounted and applied along the joint 400 while keeping the discharge amount of the sealing agent as constant as possible while referring to the method described in the instruction manual of the nozzle. “Fitting nozzle FT-10” is a product that embodies the invention of Patent Document 2. The result is shown in FIG. As shown in FIG. 7, in the sealing by coating using the sealing agent filling nozzle for automobiles of the comparative example, although the sealing can be performed linearly without being relatively curved, the unevenness of the height occurs on the sealing surface, and A thick part and a narrow part were generated. This is because in the application of the sealing agent, it is an extremely difficult task to keep the discharge amount of the sealing agent constant and to move it along the joint 400 at a constant speed.

  The present invention has been specifically described above with reference to the drawings. However, the present invention is not limited to the illustrated examples, and can be implemented with appropriate modifications within a range that can meet the spirit of the present invention. .

  For example, in the mode shown in the drawing, a rectangular notch, and a guide surface 150 and a handling surface 160 are provided in the front part 110 only on the left side of the drawing, but these are provided on the right side in the front part 110 drawing. Alternatively, they may be provided on both the left and right sides. Regarding the recesses for sealing formation, 141 and 161 have the same shape and 121 have different shapes in the drawing. However, these may be all different shapes or the same shape, or may have different shapes from the same shape and different shapes. May be present. In the embodiment shown in the drawings, the taper is provided from the center to the edge direction of the back surface 120 and the both side surfaces 130 and 140. However, all of these three directions are not necessarily tapered. However, the tapered surface 111 is an essential part to be provided. In the embodiment shown in the drawings, the edges formed by the back surface 120 and the side surface 130 or the back surface 120 and the side surface 140 are all chamfered and curved, but it is not always necessary to chamfer the portion.

  The present invention relates to a spatula for handling a sealing agent, and particularly for handling a sealing agent suitable for individually performing a sealing operation for a joint (joint) between an outer panel and an inner panel of a vehicle member. Can be applied to the spatula.
