Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the adhesive application device of Patent Document 1, the amount of adhesive extruded changes according to the number of operations of the operation lever, and the extruded adhesive is moved and spread on the floor base material by the coating portion. Therefore, it requires skill to apply a certain amount of adhesive on the floor base material according to the moving distance of the adhesive application device.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide an adhesive application device that can apply a certain amount of adhesive according to the moving distance regardless of the skill of the operator.

Means for Solving the Problems

[0006] (1) The adhesive application device according to claim 1 has a discharge port at the bottom, a housing capable of accommodating the adhesive inside, a pushing-out part that can move forward and backward with respect to the discharge port inside the housing and pushes out the adhesive from the discharge port, wheels rotatably supported outside the housing, and a conversion mechanism that converts the rotation of the wheels into the movement of the pushing-out part in the forward and backward directions. The conversion mechanism has a rack extending from the pushing-out part in a direction opposite to the discharge port, and a first pinion that meshes with the rack and rotates about a second rotation axis parallel to the first rotation axis of the wheels by the rotation of the wheels.

[0007] The rotation of the wheels in both directions is converted into the movement of the pushing-out part in the forward and backward directions via the first pinion and the rack. For this reason, the pushing-out part moves in the forward and backward directions by an amount of movement corresponding to the amount of rotation of the wheels. Therefore, an operator can apply an adhesive with a constant application amount according to the moving distance of the adhesive application device regardless of their skill level.

[0008] (2) The adhesive application device according to claim 2 is the adhesive application device according to claim 1, wherein the conversion mechanism has a belt stretched between the wheels and the first pinion.

[0009] Since the rotation of the wheels is transmitted to the first pinion via the belt, the rotation of the wheels is transmitted to the first pinion smoothly as compared with the case where the rotation of the wheels is transmitted to the first pinion via a plurality of gears. For this reason, it is easy for an operator to move the adhesive application device with the wheels pressed against the floor surface.

[0010] (3) The adhesive application device according to claim 3 is the adhesive application device according to claim 1, wherein the conversion mechanism has a second pinion that rotates about a third rotation axis parallel to the second rotation axis and meshes with the first pinion, and a belt stretched between the wheels and the second pinion.

[0011] For example, when the operator presses the wheel against the floor surface with the wheel positioned in front of the operator relative to the housing and then moves the adhesive application device forward, the first pinion, whose rotation is transmitted via the belt and the second pinion, rotates in the direction of moving the rack toward the discharge port. As a result, the extrusion part moves in the direction of advancing toward the discharge port. Therefore, since the operator can apply the adhesive while moving the adhesive application device forward, it is easy to apply the adhesive. Also, the adhesive extruded from the discharge port does not adhere to the wheel.

[0012] (4) The adhesive application device according to claim 6, wherein the rack, the first pinion, and the second pinion are covered by the housing, and it is the adhesive application device according to claim 3.

[0013] Since the housing suppresses foreign matter from coming into contact with the rack, the first pinion, and the second pinion, the conversion mechanism is less likely to malfunction.

Advantages of the Invention

[0014] According to the present invention, regardless of the skill level of the operator, an adhesive with a constant application amount can be applied according to the moving distance of the adhesive application device.

Embodiments for Carrying Out the Invention

[0016] Hereinafter, with reference to the drawings, the adhesive application device 1 according to the embodiment of the present invention will be described. It should be noted that the embodiments described below are merely examples of the present invention, and it goes without saying that the embodiments of the present invention can be appropriately changed without changing the gist of the present invention.

[0017] As shown in FIGS. 1 and 2, the adhesive application device 1 includes a housing 2, an extrusion part 3, wheels 4, and a conversion mechanism 5. The housing 2 has a substantially cylindrical shape extending along the first direction A. The housing 2 has a main body casing 11 and a sub-casing 12. The main body casing 11 has a bottom part 11A and a main body part 11B. The bottom part 11A is located at one end of the main body casing 11 in the first direction A. The bottom part 11A has a conical tube shape whose diameter decreases toward one side in the first direction A. The bottom part 11A has a discharge port 21 that penetrates one end of the bottom part 11A along the first direction A. The main body part 11B has a cylindrical shape extending from the other end of the bottom part 11A to the other side in the first direction A. The internal space of the main body part 11B communicates with the internal space of the bottom part 11A. The other end of the main body part 11B in the first direction A is open. The main body casing 11 can accommodate the adhesive through the opening at the other end of the main body part 11B in the first direction A. Note that the main body casing 11 may directly accommodate the adhesive, or may accommodate an adhesive filling bag in which the adhesive is enclosed. When the adhesive filling bag in which the adhesive is enclosed is pressed, the adhesive is pushed out to the outside through the opening located in the adhesive filling bag.

[0018] The wheel frame 22 is located near one end of the main body part 11B in the first direction A on the outer surface thereof. The wheel frame 22 is a rod-shaped frame extending from the outer surface of the main body part 11B in one direction of the second direction B orthogonal to the first direction A. A pair of engaging claws 23, 23 are located at the other end of the main body part 11B in the first direction A. The pair of engaging claws 23, 23 are located on both sides of the second direction B on the outer surface of the main body part 11B. The pair of engaging claws 23, 23 protrude from the other end of the main body part 11B in the other direction of the first direction A. The pair of engaging claws 23, 23 are elastically deformable outward in the second direction B.

[0019] The sub-casing 12 is connected to the other end of the main body part 11B. The sub-casing 12 has a rectangular tube shape extending from the other end of the main body part 11B in the other direction of the first direction A. The internal space of the sub-casing 12 communicates with the internal space of the main body part 11B. The other end of the sub-casing 12 in the first direction A is open. The length L1 of the sub-casing 12 along the first direction A is shorter than the length L2 of the main body part 11B along the first direction A. The length L3 of the sub-casing 12 along the second direction B is substantially equal to the length L4 of the main body part 11B along the second direction B. The length L5 of the sub-casing 12 along the third direction C orthogonal to the first direction A and the second direction B is shorter than the length L6 of the main body part 11B along the third direction C. A belt through-hole 24 is located on one side of the sub-casing 12 in the second direction B. The belt through-hole 24 penetrates the sub-casing 12 along the second direction B. The belt through-hole 24 has a rectangular shape with a longer length in the first direction A than in the third direction C.

[0020] A pair of engaging grooves 25, 25 are located at one end of the sub-casing 12 in the first direction A on the outer surface thereof. The pair of engaging grooves 25, 25 are located on both sides of the second direction B on the outer surface of the sub-casing 12. The pair of engaging grooves 25, 25 are recesses recessed from the outer surface of the sub-casing 12. The pair of engaging claws 23, 23 are fitted into the pair of engaging grooves 25, 25 in a state of being elastically deformed outward in the second direction B. Thereby, the sub-casing 12 is detachably attached to the other end of the main body casing 11 in the first direction A.

[0021] The extrusion part 3 is located in the internal space of the main body part 11B of the main body casing 11. The extrusion part 3 is circular and has a diameter slightly smaller than the inner diameter of the main body part 11B. The extrusion part 3 can advance and retreat along the first direction A in the internal space of the main body part 11B. The first direction A is an example of the advancing and retreating direction.

[0022] The wheel 4 is located outside the housing 2. The wheel 4 has a first rotating shaft 4A rotatably supported by the wheel frame 22. The first rotating shaft 4A extends along the third direction C. The wheel 4 is rotatable about the first rotating shaft 4A.

[0023] The conversion mechanism 5 has a rack 32, a first pinion 33, a second pinion 34, and a belt 35. The rack 32 has a flat plate part 32A and a plurality of teeth 32B. The flat plate part 32A is located across the internal space of the main body part 11B to the internal space of the sub-casing 12. The flat plate part 32A is connected to the surface of the extrusion part 3 on the side opposite to the discharge port 21. The flat plate part 32A extends from the extrusion part 3 toward the other side in the first direction A. The flat plate part 32A is in a flat plate shape that spreads in the first direction A and the third direction C. The length L7 of the flat plate part 32A along the first direction A is substantially equal to the length L1 of the sub-casing 12 along the first direction A plus the length L2 of the main body part 11B along the first direction A.

[0024] The plurality of teeth 32B are located on one surface of the flat plate part 32A in the second direction B. The plurality of teeth 32B are arranged from one end to the other end of the flat plate part 32A along the first direction A.

[0025] As shown in FIG. 3, the rack 32 has support grooves 32C extending along the first direction A on both side surfaces of the flat plate portion 32A in the third direction C. Each support groove 32C is recessed from each side surface of the flat plate portion 32A. Each support groove 32C is located from the vicinity of one end of the flat plate portion 32A in the first direction A to the vicinity of the other end of the flat plate portion 32A in the first direction A. As shown in FIG. 4, each support groove 32C has inserted therein support pieces 36 extending inward in the third direction C from both sides in the third direction C of the inner surface of the sub-casing 12. Each support piece 36 is prevented from coming out in the first direction A from each support groove 32C. Thereby, the rack 32 is supported by the two support pieces 36 so as to be movable along the first direction A.

[0026] The entire rack 32 is covered by the main body portion 11B and the sub-casing 12 when the pushing portion 3 is located at one end in the first direction A in the internal space of the main body portion 11B. As shown in FIG. 2, when the pushing portion 3 is located on the other side of one end in the first direction A in the internal space of the main body portion 11B, the other end of the rack 32 in the first direction A is exposed from the sub-casing 12.

[0027] The first pinion 33 is located in the internal space of the sub-casing 12. Thereby, the entire first pinion 33 is covered by the sub-casing 12. The first pinion 33 has a second rotation shaft 33A rotatably supported on the inner surface of the sub-casing 12. The second rotation shaft 33A extends along the third direction C parallel to the first rotation shaft 4A. The first pinion 33 rotates about the second rotation shaft 33A and meshes with a plurality of teeth 32B of the rack 32.

[0028] The second pinion 34 is located in the internal space of the sub-casing 12. As a result, the entire second pinion 34 is covered by the sub-casing 12. The second pinion 34 is located on one side of the first pinion 33 in the first direction A. The second pinion 34 has a third rotation axis 34A that is rotatably supported on the inner surface of the sub-casing 12. The third rotation axis 34A extends along a third direction C parallel to the second rotation axis 33A. The second pinion 34 rotates about the third rotation axis 34A. The second pinion 34 meshes with the first pinion 33.

[0029] As shown in FIG. 2, the tip circle diameter D4 and the number of teeth of the second pinion 34 are the same as the tip circle diameter D5 and the number of teeth of the first pinion 33. The diameter D1 of the third rotation axis 34A is the same as the diameter D2 of the second rotation axis 33A. The diameter D1 of the third rotation axis 34A is smaller than the diameter D3 of the first rotation axis 4A of the wheel 4. The tip circle diameter D4 of the second pinion 34 is smaller than the diameter D6 of the wheel 4.

[0030] The belt 35 is stretched across the first rotation axis 4A of the wheel 4 and the third rotation axis 34A of the second pinion 34 through the belt through-hole 24 of the sub-casing 12. As a result, the rotation of the wheel 4 in both directions can be transmitted to the first pinion 33 via the belt 35 and the second pinion 34. When the rotation of the wheel 4 in both directions is transmitted to the first pinion 33, the rack 32 that meshes with the first pinion 33 moves along the first direction A, so that the extrusion part 3 moves along the first direction A. In this way, the rotation of the wheel 4 in both directions is converted into the movement of the extrusion part 3 in the forward and backward directions.

[0031] The moving distance of the extrusion section 3 and the discharge amount from the discharge port 21 of the adhesive can be adjusted by changing the ratio of the diameter D3 of the first rotation axis 4A of the wheel 4 to the diameter D6 of the wheel 4, or by changing the ratio of the diameter D1 of the third rotation axis 34A of the second pinion 34 to the diameter D3 of the first rotation axis 4A of the wheel 4, or by changing the ratio of the tip circle diameter D4 of the second pinion 34 to the diameter D1 of the third rotation axis 34A of the second pinion 34. For example, when the ratio of the diameter D3 of the first rotation axis 4A of the wheel 4 to the diameter D6 of the wheel 4 is increased, the moving distance of the extrusion section 3 becomes longer. Conversely, when the ratio of the diameter D3 of the first rotation axis 4A of the wheel 4 to the diameter D6 of the wheel 4 is decreased, the moving distance of the extrusion section 3 becomes shorter. Also, when the ratio of the diameter D1 of the third rotation axis 34A of the second pinion 34 to the diameter D3 of the first rotation axis 4A of the wheel 4 is decreased, the moving distance of the extrusion section 3 becomes longer. Conversely, when the ratio of the diameter D1 of the third rotation axis 34A of the second pinion 34 to the diameter D3 of the first rotation axis 4A of the wheel 4 is increased, the moving distance of the extrusion section 3 becomes shorter. Further, when the ratio of the tip circle diameter D4 of the second pinion 34 to the diameter D1 of the third rotation axis 34A of the second pinion 34 is increased, the moving distance of the extrusion section 3 becomes longer. Conversely, when the ratio of the tip circle diameter D4 of the second pinion 34 to the diameter D1 of the third rotation axis 34A of the second pinion 34 is decreased, the moving distance of the extrusion section 3 becomes shorter.

[0032] Also, by changing the size of the discharge port 21, the ease of discharge of the adhesive from the discharge port 21 can be adjusted. For example, when the discharge port 21 is enlarged, the moving resistance of the adhesive in the main body casing 11 becomes smaller, so the adhesive is more easily discharged from the discharge port 21. Conversely, when the discharge port 21 is reduced, the moving resistance of the adhesive in the main body casing 11 becomes larger, so the adhesive is less easily discharged from the discharge port 21.

[0033] Next, the method of using the adhesive application device 1 will be described. In the initial state, an adhesive-filled bag containing the adhesive is housed in the main body casing 11. When housing the adhesive in the main body casing 11, the operator removes the belt 35 from the first rotation shaft 4A of the wheel 4 and then removes the sub-casing 12 from the main body casing 11. Next, the operator houses the adhesive through the opening at the other end of the main body portion 11B in the first direction A. Next, the operator attaches the sub-casing 12 to the main body casing 11 by fitting a pair of engagement claws 23, 23 of the main body casing 11 into a pair of engagement grooves 25, 25 of the sub-casing 12. Finally, the operator passes the belt 35 over the first rotation shaft 4A of the wheel 4.

[0034] As shown in FIG. 2, the operator presses the wheel 4 against the floor underlayment 41 with the wheel 4 positioned in front of the operator relative to the housing 2. Next, the operator moves the adhesive application device 1 toward the operator's front side. As a result, the wheel 4 rotates clockwise in FIG. 2. The rotation of the wheel 4 is transmitted to the second pinion 34 via the belt 35. As a result, the second pinion 34 rotates clockwise in FIG. 2. The first pinion 33 meshing with the second pinion 34 rotates counterclockwise in FIG. 2. The rack 32 meshing with the first pinion 33 moves in one direction of the first direction A toward the discharge port 21. The extrusion portion 3 connected to the rack 32 moves in one direction of the first direction A toward the discharge port 21. As a result, the adhesive is extruded from the discharge port 21 and applied onto the floor underlayment 41.

[0035] [Operation and Effect of the Embodiment] In the adhesive application device 1, the rotation of the wheel 4 in both directions is converted into the movement of the extrusion portion 3 along the first direction A via the belt 35, the second pinion 34, the first pinion 33, and the rack 32. For this reason, the extrusion portion 3 moves in the first direction A by an amount of movement corresponding to the amount of rotation of the wheel 4. Therefore, the operator can apply a constant amount of adhesive according to the movement distance of the adhesive application device 1 regardless of skill.

[0036] In the adhesive application device 1, since the rotation of the wheel 4 is transmitted to the second pinion 34 via the belt 35, the rotation of the wheel 4 is transmitted to the second pinion 34 more smoothly than in the case where the rotation of the wheel 4 is transmitted to the second pinion 34 via a plurality of gears. Therefore, it is easy for the operator to move the adhesive application device 1 with the wheel 4 pressed against the floor surface.

[0037] In the adhesive application device 1, when the operator presses the wheel 4 against the floor surface with the wheel 4 positioned in front of the operator with respect to the housing 2 and moves the adhesive application device 1 forward, the first pinion 33 to which the rotation of the wheel 4 is transmitted via the belt 35 and the second pinion 34 rotates counterclockwise in FIG. 2, and the rack 32 moves in one direction A toward the discharge port 21. Therefore, the extrusion part 3 moves in one direction A toward the discharge port 21. For this reason, the operator can apply the adhesive while moving the adhesive application device 1 forward, so that it is easy to apply the adhesive. Further, the adhesive discharged from the discharge port 21 does not adhere to the wheel 4.

[0038] In the adhesive application device 1, the rack 32, the first pinion 33, and the second pinion 34 are covered with the sub-casing 12. Therefore, since the sub-casing 12 suppresses foreign matter from coming into contact with the rack 32, the first pinion 33, and the second pinion 34, the conversion mechanism 5 is less likely to malfunction.

[0039] [Modification Example] In the adhesive application device 1, although the rotation of the wheel 4 is transmitted to the second pinion 34 via the belt 35, as long as the rotation of the wheel 4 can be transmitted to the second pinion 34, it is not limited to the belt transmission mechanism. For example, the rotation of the wheel 4 may be transmitted to the second pinion 34 via a plurality of gears.

[0040] In the adhesive application device 1, the conversion mechanism 5 has the first pinion 33 and the second pinion 34. However, as shown in FIG. 5, the second pinion 34 may be omitted. In this case, the belt 35 is stretched between the first rotation shaft 4A of the wheel 4 and the second rotation shaft 33A of the first pinion 33. In the adhesive application device 1 of the modified example, when the operator moves the adhesive application device 1 so that the wheel 4 rotates counterclockwise in FIG. 5, the first pinion 33 rotates counterclockwise in FIG. 5, so that the rack 32 moves in one direction A of the first direction A toward the discharge port 21, and the extrusion part 3 moves in one direction A of the first direction A toward the discharge port 21. As a result, the adhesive is extruded from the discharge port 21. In this case, in order to prevent the adhesive extruded from the discharge port 21 from adhering to the wheel 4, as shown in FIG. 6, the wheel 4 may be arranged at two positions that do not coincide with the discharge port 21 in the third direction C.

[0041] In the adhesive application device 1, the diameter D1 of the third rotation shaft 34A of the second pinion 34 was smaller than the diameter D3 of the first rotation shaft 4A of the wheel 4, but it may have a length equal to or greater than the diameter D3 of the first rotation shaft 4A of the wheel 4. By doing so, the rotation speeds of the second pinion 34 and the first pinion 33 become slower, so that the moving distances of the rack 32 and the extrusion part 3 become shorter with respect to the rotation amount of the wheel 4. For this reason, the user can apply less adhesive with respect to a certain moving distance of the adhesive application device 1.

[0042] In the adhesive application device 1, the length L7 of the flat plate part 32A of the rack 32 along the first direction A was substantially equal to the length L1 of the sub-casing 12 along the first direction A plus the length L2 of the main body part 11B along the first direction A, but it may be longer than the length obtained by adding the length L2 of the main body part 11B to the length L1 of the sub-casing 12. Further, the length L7 of the rack 32 may be shorter than the length obtained by adding the length L2 of the main body part 11B to the length L1 of the sub-casing 12 as long as the engagement between the rack 32 and the first pinion 33 can be maintained when the extrusion part 3 is located at one end in the main body part 11B.

[0043] In the adhesive applicator 1, when the extrusion part 3 is located on the other side of one end in the first direction A in the internal space of the main body part 11B, the other end of the rack 32 in the first direction A is exposed from the sub-casing 12. However, for example, by increasing the length of the sub-casing 12 along the first direction A, the entire rack 32 may be covered by the main body part 11B and the sub-casing 12 regardless of the position of the extrusion part 3.

[0044] In the adhesive applicator 1, the entire first pinion 33 was covered by the sub-casing 12. However, if the first pinion 33 is rotatably supported by the sub-casing 12, at least a part of the first pinion 33 may be exposed from the sub-casing 12. Also, the first pinion 33 may be rotatably supported by the main body part 11B. Further, the entire second pinion 34 was covered by the sub-casing 12. However, if the second pinion 34 is rotatably supported by the sub-casing 12, at least a part of the second pinion 34 may be exposed from the sub-casing 12. Also, the second pinion 34 may be rotatably supported by the main body part 11B.

[0045] In the adhesive applicator 1, the rack 32 is movably supported along the first direction A by two support pieces 36 extending inward from the inner surface of the sub-casing 12, but it may be movably supported along the first direction A by the inner surface of the main body part 11B. When the rack 32, the first pinion 33, and the second pinion 34 are supported by the main body part 11B, the sub-casing 12 may be omitted.

[0046] In the adhesive applicator 1, the sub-casing 12 is detachably attached to the main body casing 11 by fitting a pair of engagement claws 23, 23 into a pair of engagement grooves 25, 25 in a state where they are elastically deformed outward in the second direction B. However, if it is detachable from the main body casing 11, it is not limited to the pair of engagement claws 23, 23 and the pair of engagement grooves 25, 25. For example, the sub-casing 12 may be detachably attached to the main body casing 11 by being press-fitted into the main body casing 11.

[0047] [Appendix 1] It has a discharge port at the bottom and a housing capable of accommodating an adhesive inside, a pushing part that can move forward and backward in the housing with respect to the discharge port and push out the adhesive from the discharge port, wheels rotatably supported outside the housing, and a conversion mechanism that converts the rotation of the wheels into the movement of the pushing part in the forward and backward directions, and is provided with, The conversion mechanism is a rack extending from the pushing part in a direction opposite to the discharge port, and a first pinion that meshes with the rack and rotates around a second rotation axis parallel to the first rotation axis of the wheels by the rotation of the wheels.
