[0003]

The conventional hand painting operation has the following disadvantages. (1) Although it depends on the skill of the worker, it is generally difficult to ensure the uniformity of the applied state of the adhesive in the hand coating work. For this reason, even when the adhesive is applied to the surface to be applied in a parallel line shape at a predetermined interval, the worker may apply the adhesive to the entire surface of the surface to be applied, and the consumption of the adhesive may increase. (2) Since the adhesive dries as soon as it comes into contact with air, it is necessary to minimize the application time, for example, in units of ceiling boards that are simultaneously applied. This makes the work even more difficult. If the adhesive has dried, the operation is interrupted and the operation must be repeated. (3) On the other hand, since the application of the adhesive is basically performed manually, the equipment used for the operation must be light enough to be held for a long time by a human even in a state where the adhesive is contained. SUMMARY OF THE INVENTION An object of the present invention is to provide an adhesive applicator capable of efficiently applying an adhesive such as glue to an object to be applied in order to solve such problems in the conventional technology. .

The adhesive applicator according to the present embodiment is shown in FIG.
As shown in the figure, a main body 1 for storing an adhesive such as glue,
The lower part is immersed in the adhesive 2 stored in the main body 1,
A grooved roller 3 rotatably supported at both ends in the main body 1 so that the upper part is exposed outside the main body 1, and the upper part of the roller 3 is brought into contact with an application target surface (application target) 4. The adhesive 2 is applied to the surface 4 to be applied by being rotated. Hereinafter, the detailed structure of the present adhesive applicator will be described with reference to FIGS. (Structure of the main body 1) The main body 1 of the present adhesive applicator has a rectangular open tank structure in plan view as shown in FIGS. 2 and 3, and its cross section is as shown in FIG. , A semicircular arc formed along the lower part of the roller 3.
Thus, the bottom of the main body 1 has a curved surface slightly larger than the diameter of the roller 3, and the shape of the main body 1 is minimized. As a material for the main body 1, a thin aluminum plate is used for weight reduction. However, it is a matter of course that a resin material may be used if there is no problem in strength or the like. Further, as shown in FIG. 4, the main body 1 is provided with a grip 1a which can be held horizontally, vertically and obliquely with respect to the surface 4 to be coated. The coating operation can be performed from any angle without taking a proper posture. The grip portion 1a is formed by bending an aluminum round pipe and is fixed near the top and bottom of the main body 1 by welding, screws, or the like, thereby reducing the weight. As shown in FIGS. 2 and 3, the grips 1a are provided near both ends in the longitudinal direction of the main body 1 so that the user can hold the grips firmly with both hands. Pipes of the same diameter are connected between them to provide the required strength. However, a resin material may be used here.

(Structure of Roller 3) The roller 3 is formed by arranging a plurality of discs 3a, 3a,... Made of aluminum or resin in a coaxial manner. The case where a disk is arranged is illustrated. In the figure, these disks 3a, 3a,... Are fixed to the same shaft 3b of an aluminum round pipe at equal intervals. However, the disks 3a, 3a,... Do not necessarily need to be fixed to the shaft 3b. For example, the disks 3a, 3a,. By changing the length of the discs 3a, 3a, ...
Can be adjusted. Accordingly, it is possible to cope with various sizes, weights, and the like of a ceiling board or the like that is attached to a ceiling or the like as the application target surface 4 by changing the application pattern. Each of these disks 3a, 3a, ... has grooves 3c, 3c, ... formed continuously in the circumferential direction. The grooves 3c, 3c,... Have, for example, a U-shaped cross section or a V-shaped cross section, and have a depth such that a predetermined amount of the adhesive 2 to be applied can be held here by the adhesive force. I have. However, as shown in FIG. 5, these disks 3a ′, 3a ′,... May have grooves 3c ′, 3c ′,. In that case, intermittent application becomes possible and the adhesive 2
Consumption can be further reduced. Also, as shown in FIG. 4, the disks 3a have through holes 3d formed on the side surfaces thereof. Through hole 3
The size of d, 3d,... is made as large as possible within a range that does not cause a problem in the strength of the disks 3a, 3a,.
During the rotation, the adhesive 2 stored in the main body 1 is flowed and agitated to prevent the adhesive 2 from drying and hardening during the operation. In the figure, five round holes having the same diameter are arranged equidistantly and equiangularly with respect to the center of the disk so that the rotation of the roller 3 becomes smooth. , 3
The shape of d,... is not limited to this. (Supporting Structure of Roller 3) The roller 3 can be detached at both ends of the body 1 so that maintenance such as cleaning can be easily performed. Specifically, the shaft support portions at both ends in the main body 1 are constituted by U-shaped bearing plates 1b, 1b from which the shaft ends 3e, 3e of the roller 3 can be removed upward. The material of the bearing plates 1b, 1b is made of aluminum or resin in order to reduce the weight.
For e and 3e, a round bar made of stainless steel is used to prevent corrosion by the adhesive 2 and to prevent distortion due to the weight of the roller 3, and the round bar is inserted into and fixed to the hollow portions at both ends of the shaft 3b. . Hereinafter, the operation of the present adhesive applicator will be described.

(When Applying Adhesive) As shown in FIG. 1, the main body 1 is filled with an adhesive 2 in an appropriate amount. At this time, the lower part of the roller 3 is immersed in the adhesive 2, and the adhesive 2 enters the grooves 3c, 3c,..., But the upper part of the roller 3 is exposed outside the main body 1. The adhesive 2 does not enter the grooves 3c. When the user grips the holding portion 1a with both hands and applies the roller 3 exposed to the outside of the main body 1 to the application target surface 4 to move the main body 1, the frictional force between the roller 3 and the application target surface 4 causes the roller 3 to move. Start rotation of 3. The grip portion of the grip portion 1a at this time differs depending on the relative positional relationship between the user and the coating target surface 4. That is,
When the surface 4 to be coated with the adhesive 2 is a high ceiling surface,
When the user needs to reach out and lift the main body 1 upward, the user grasps the part in FIG.
And hold it parallel to the ceiling. When the application target 4 of the adhesive 2 is a low ceiling surface and the user needs to reach out and extend the main body 1 forward, the user grasps the part in FIG. And hold it parallel to the ceiling surface. In addition, adhesive 2
When the application target 4 is a ceiling surface of an intermediate height, the user grasps the portion in FIG. 4 and inserts the main body 1 obliquely forward and holds it in parallel with the ceiling surface. Then, the groove 3 of the roller 3
The adhesive 2 held in c, 3c,... is supplied from the main body 1 to the surface 4 to be applied in a fixed amount, and the four lines are simultaneously applied. In the present adhesive applicator, even if the amount of the adhesive 2 is reduced by use, the adhesive 2 in the main body 1 can be almost completely used because the bottom of the main body 1 is along the lower part of the roller 3. it can. After the adhesive 2 is applied to the surface 4 to be applied as described above, a ceiling board or the like is stuck to a corresponding portion of the surface 4 to be applied while the adhesive 2 is not dried.

(At the time of maintenance) At the time of maintenance,
As shown in FIG. 1, the user takes out the roller 3 from the main body 1 and cleans the main body 1 and the roller 3 separately. Thereby, the clearance between the main body 1 and the roller 3 and the bearing plates 1b, 1b in the main body 1 and the shaft end 3 of the roller 3
It is possible to prevent the adhesive 2 from remaining and being dried and fixed between e and 3e. After the maintenance, the user places the rollers 3 on the bearing plates 1b, 1b in the main body 1.
The shaft ends 3e, 3e are fitted from above and the roller 3 is set in the main body 1 to return to the original state. At this time, the type and number of the disks 3c, 3c,... Of the roller 3 may be changed as necessary, or the intervals between the disks 3c, 3c,. It is considered possible. In this manner, in the present embodiment, the lower portion of the roller 3 is immersed in the adhesive 2 stored in the main body 1, so that a fixed amount of the adhesive 2 is held in the roller groove. Then, the upper portion of the roller 2 exposed outside the main body 1 is rotated by hitting the upper portion of the roller 2 against the coating target 4.
Since the adhesive 2 held in the roller grooves is supplied to the application target surface 4 by a constant amount, the application state of the adhesive 2 becomes uniform. Along with this, the consumption of the adhesive 2 becomes smaller than before. In this case, the distance between the main body 1 and the surface 4 to be applied is short, and the application time is also short. Therefore, there is little possibility that the adhesive 2 dries during this time and the work is interrupted. As a result, the adhesive 2 can be efficiently applied to the surface 4 to be applied.

[0010]

In the above embodiment, the disk 3a of the roller 3
Although the number of 3a ... is four, the number of disks may be increased to extend the area that can be painted at one time as long as the weight permits, or vice versa. May be reduced to reduce the area that can be painted at once. FIG. 6 shows that the number of disks 3a ", 3a".
The case where the number is increased is illustrated. In this case, eight lines are applied simultaneously, and the disk 3 of the roller 3
Since the width in which the adhesive 2 "can be applied is doubled as compared with the case where the number of a, 3a,... is four, the work efficiency is also considered to be doubled. May involve multiple people working together.
