Description

[Technical Field]

[0001] The present invention relates to a method for forming a laminated material by stacking layer materials each made of a clay-like strip material laid and reinforced with wire material. [Background technology]

[0002] Conventionally, there has been known a method for forming a laminated material by stacking laid strips of clay-like hardening material such as mortar, etc. Patent Document 1 discloses a method for reinforcing laid strips by supplying flexible wires through a supply port for supplying hardening material to the laying surface. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-184275 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the method described in Patent Document 1, the supply port for the strip material may be blocked by the wire material. [Means for solving the problem]

[0005] A laminated material molding method that solves the above problem is a laminated material molding method that molds a laminated material by stacking layer materials having laid strip material in which clay-like strip material is laid in the laying direction and wire material embedded in the laid strip material so as to extend in the laying direction, and a strip material supply port that supplies the strip material to the laying surface and a wire material supply port that supplies the wire material to the laid strip material are aligned in the laying direction.

[0006] According to the above configuration, the strip material supply port and the wire material supply port are separate and are aligned in the laying direction, so that the wire material can be embedded in the laid strip material so that it extends in the laying direction while preventing the wire material from clogging the strip material supply port.

[0007] In the laminate molding method, the strip material supply port and the wire material supply port may be provided in a trowel that holds the strip material. According to the above-mentioned configuration, the wire can be embedded in the strip material that has been leveled by the trowel, and the degree of freedom in terms of the embedding position of the wire in the width direction of the strip material is also improved.

[0008] In the laminate molding method, the wire rod supply port may be provided behind the strip rod supply port in the laying direction and supply the wire rod to an upper surface of the laid strip rod. According to the above configuration, the wire supply port is provided behind the strip supply port, so that the wire can be buried on the upper surface of the laid strip.

[0009] In the laminate molding method, the wire rod supply port may be provided in front of the strip rod supply port in the laying direction to supply the wire rod into the inside of the laid strip rod. According to the above configuration, since the wire supply port is provided in front of the strip supply port, the wire can be embedded inside the laid strip.

[0010] The above-mentioned laminate molding method may include a first wire rod and a second wire rod as the wire rods, and a first wire rod supply port for supplying the first wire rod and a second wire rod supply port for supplying the second wire rod as the wire rod supply ports, and the first wire rod supply port and the second wire rod supply port may be arranged in front of the strip rod supply port in the laying direction and at different positions in the height direction of the laid strip rods.

[0011] According to the above-mentioned configuration, the wires can be embedded at different positions in the height direction relative to the laid strip material, thereby increasing the strength of the layer material and, ultimately, the laminate material. [Brief explanation of the drawings]

[0013] (First embodiment) A first embodiment of a laminate molding method will be described with reference to FIGS. As shown in FIG. 1, the laminated material 10 is formed by laminating layer materials 13 each composed of a laying strip material 11 and a wire material 12 embedded in the laying strip material 11.

[0014] The layer material 13 is formed by a 3D printer 20. The 3D printer 20 has a strip material laying unit 21 and a wire material supply unit 31. The strip material laying unit 21 lays the strip material 11 to be laid on a laying surface 15. The wire material supply unit 31 supplies wire material 12 to the strip material 11 to be laid. The strip material laying unit 21 and the wire material supply unit 31 are configured to be movable in the laying direction X while maintaining their relative positions by a robot arm (not shown) or the like. In FIG. 1, the top surface of the layer material 13 formed previously is referred to as the laying surface 15. In the following, the strip material laying unit 21 and the wire material supply unit 31 are collectively referred to as a molding unit.

[0015] The strip laying unit 21 moves in the laying direction X and supplies a clay-like hardening material to the laying surface 15, thereby laying strips 11 extending in the laying direction X on the laying surface 15. The clay-like hardening material is, for example, mortar. The strip laying unit 21 has a nozzle 24 and a trowel 25. The clay-like hardening material is pressure-fed to the nozzle 24 through a hose (not shown). The trowel 25 is provided at the lower end of the nozzle 24. The trowel 25 has a strip supply port 27. The strip supply port 27 supplies the hardening material pressure-fed to the nozzle 24 to the laying surface 15 as strips. The trowel 25 presses down the strip material laid on the laying surface 15 from the strip material supply port 27 with the pressing surface 25a, thereby forming a laid strip material 11 having a height corresponding to the distance between the laying surface 15 and the pressing surface 25a and a width corresponding to the amount of hardenable material supplied.

[0016] The wire supply unit 31 supplies the wire 12 to the strip 11 while moving in the laying direction X. The wire supply unit 31 supplies the wire 12 through a wire supply port 32. In the first embodiment, the wire supply port 32 is provided behind the strip supply port 27 in the laying direction X. More specifically, the wire supply port 32 is provided in the trowel 25 and opens to the pressing surface 25a of the trowel 25.

[0017] The wire supply unit 31 has a wire feeder 33. The wire feeder 33 is configured to be rotatable around a rotary shaft 34 extending perpendicular to the plane of the drawing. A wire 12 is wound around the wire feeder 33. The wire 12 is a member that has a greater tensile strength than the clay material after hardening, such as steel fiber, organic fiber, or chain, and serves to reinforce the laying strip 11.

[0018] The wire rod feeding machine 33 may be configured to be rotationally driven so as to feed the wire rod 12 at a feeding speed corresponding to the moving speed of the molding unit, or may be configured to rotate automatically due to the frictional force between the laying strip material 11 and the wire rod 12 supplied to the laying strip material 11.

[0019] The wire rod supply unit 31 may have a direction changer 35. The direction changer 35 is installed depending on the positional relationship between the wire rod supply port 32 and the wire rod delivery machine 33. The direction changer 35 changes the direction of the wire rod 12, thereby guiding the wire rod 12 delivered by the wire rod delivery machine 33 to the wire rod supply port 32.

[0020] The wire supply section 31 is configured so that the number of wires 12 to be embedded in the laying strip 11 depends on the width of the laying strip 11 and the strength required for the layer material 13 . For example, as shown in Fig. 2(a), the wire supply unit 31 is configured to supply one wire 12 to one laying strip 11. In this case, the wire supply unit 31 is configured to embed the wire 12 in the center of the width direction of the laying strip 11 when viewed from above.

[0021] 2(b), the wire supply unit 31 is configured to supply three wires 12 to one laying strip 11. In this case, the wire supply unit 31 is configured to embed the wires 12 on both sides of the widthwise center of the laying strip 11 in addition to the widthwise center when viewed from above.

[0022] (Operation of the first embodiment) The 3D printer 20 has a wire material supply port 32 behind the strip material supply port 27 in the laying direction X. The 3D printer 20 supplies strip material from the strip material supply port 27 and wire material 12 from the wire material supply port 32 while moving the molding unit in the laying direction X. In this way, the 3D printer 20 forms a layer material 13 on the laying surface 15, which is composed of laid strip material 11 extending in the laying direction X and wire material 12 extending in the laying direction X and embedded in the upper surface of the laid strip material 11. The 3D printer 20 forms the laminated material 10 by stacking these layer materials 13.

[0023] The effects of the first embodiment will be described. (1-1) In the laminated material molding method, a laminated material 10 is molded by stacking layer materials 13 each having laid strips 11 made of clay-like strips laid in a laying direction X and wires 12 embedded in the laid strips 11. In the laminated material molding method, a strip supply port 27 for supplying a hardenable material as strips to a laying surface 15 and a wire supply port 32 for supplying wires 12 to the laid strips 11 are aligned in the laying direction X, so that the wires 12 are embedded in the laid strips 11 so as to extend in the laying direction X.

[0024] In this way, the wire 12 is supplied to the laid strip 11 from the wire supply port 32 installed at a position different from the strip supply port 27, so the strip supply port 27 does not become clogged with the wire 12.

[0025] (1-2) The strip material supply port 27 and the wire material supply port 32 are provided on the trowel 25. As a result, the strip material supply port 27 and the wire material supply port 32 can be moved while maintaining their relative positions simply by moving the trowel 25 in the laying direction X.

[0026] (1-3) The wire 12 is supplied to the upper surface of the laid strip 11 from a wire supply port 32 provided behind the strip supply port 27 in the laying direction X. This makes it possible to form a layer material 13 in which the wire 12 is embedded in the upper surface of the laid strip 11. In addition, the wire 12 can be embedded in the interlayer space between two layer materials 13 that are stacked.

[0027] (1-4) By embedding multiple wires 12 aligned in the width direction in the laying strip 11, it is possible to embed the number of wires 12 according to the width of the laying strip 11. As a result, the strength of the layer material 13 and, ultimately, the laminated material 10 can be increased.

[0028] (Second embodiment) A second embodiment of the laminate molding method will be described with reference to Figure 3. The laminate molding method of the second embodiment has the same main configuration as the laminate molding method of the first embodiment. Therefore, in the second embodiment, only the parts that differ from the first embodiment will be described in detail, and parts that are the same as those in the first embodiment will be denoted by the same reference numerals and will not be described in detail again.

[0029] 3, in the 3D printer 20, the wire supply port 32 is provided in front of the strip supply port 27. The wire supply port 32 is provided in a wire guide 38 located between the pressing surface 25a of the trowel 25 and the laying surface 15. The wire guide 38 guides the wire 12, which is supplied through a wire guide path 28 provided in the trowel 25, to the laying strip 11.

[0030] (Operation of the second embodiment) The 3D printer 20 has a wire supply port 32 in front of the strip supply port 27 in the laying direction X. The wire 12 supplied from the wire supply port 32 is supplied into the inside of the laying strip 11 laid rearward in the laying direction X.

(2-1) The wire supply port 32 is provided in front of the strip supply port 27 in the laying direction X. The wire supply port 32 supplies the wire 12 into the inside of the laying strip 11. This allows the wire 12 extending in the laying direction X to be arranged inside the laying strip 11.

[0032] (Third embodiment) A third embodiment of the laminate molding method will be described with reference to Figure 4. The laminate molding method of the third embodiment has the same main configuration as the laminate molding method of the first embodiment. Therefore, in the third embodiment, only the parts that differ from the first embodiment will be described in detail, and the parts that are the same as those in the first embodiment will be denoted by the same reference numerals and will not be described in detail again.

[0033] 4, the 3D printer 20 has a first wire rod supply unit 41 and a second wire rod supply unit 42. The basic configurations of the first wire rod supply unit 41 and the second wire rod supply unit 42 are the same as those of the wire rod supply unit 31 of the first embodiment.

The first wire supply port 43 is provided in a first wire guide 46 located between the laying surface 15 and the pressing surface 25a. The first wire guide 46 guides the first wire 45, which is supplied through a first wire guide path 44 provided in the trowel 25, to the laying strip 11. The first wire supply port 43 supplies the first wire 45 to a portion of the laying strip 11 near the top surface.

[0035] The second wire supply section 42 has a second wire supply port 48 in front of the strip supply port 27. The second wire supply port 48 is provided in front of the first wire supply port 43 in the laying direction X and closer to the laying surface 15 than the first wire supply port 43. The second wire supply port 48 is provided in a second wire guide 47 located between the laying surface 15 and the pressing surface 25a. The second wire guide 47 receives the second wire 50 through a second wire guide path 49 provided in the trowel 25. The second wire guide path 49 is provided forward of the first wire guide path 44 in the laying direction X. The second wire guide 47 guides the second wire 50 supplied through the second wire guide path 49 to the laying strip 11. The second wire supply port 48 supplies the second wire 50 to a portion of the laying strip 11 closer to the laying surface 15.

[0036] (Operation of the third embodiment) The 3D printer 20 has a first wire rod supply port 43 and a second wire rod supply port 48 in front of the strip rod supply port 27 in the laying direction X.
