Japanese Unexamined Patent Publication No. 2014-9004

Here, the inventor of the present application shapes the discharged material discharged from the discharge hole into a modeled object having a desired three-dimensional shape on the discharge container before supplying the discharged material to a position away from the discharge container, such as a portion to be coated. I came up with the idea of doing it. It should be noted that, for example, the added value of the discharge container is expected to be improved by modeling the discharged product into a modeled object in this way.

The present invention has been made in view of the above circumstances, and an object of the present invention is to form a modeled object with high accuracy.

In order to solve the above problems, the present invention proposes the following means.
In the modeling head according to the present invention, a communication hole is formed in the discharge hole of the discharge container, and a bottomed tubular mounting portion mounted on the discharge hole and a discharge product discharged from the discharge hole are each formed. A plurality of molding pieces having a plurality of molding holes that pass separately and a molding surface through which these molding holes open, and a plurality of molding pieces formed by each of the discharges formed by passing through the plurality of molding holes separately, are formed. The modeling portion includes a modeling portion that is combined on a surface to form a modeled object, and the modeling portion extends downward from the main body portion whose surface facing upward is the modeling surface, and the mounting portion. It is provided with an operation cylinder portion fitted from the outside in the radial direction and a seal cylinder portion extending downward from the main body portion and fitting into the mounting portion, and between the mounting portion and the modeling portion. Is provided with a diffusion chamber that diffuses the discharged material discharged from the discharge hole in the radial direction along the molding surface and supplies it to each of the plurality of molding holes, and the diffusion chamber is provided through the communication hole. A regulating member facing the discharge hole is provided, and the regulating member is connected to the opening peripheral edge of the communication hole via a bridge portion, and the bridge portion extends upward from the inner peripheral surface of the communication hole. It is characterized in that it is fixed to the lower surface of the regulating member.

In this case, the discharged material discharged from the discharge holes of the discharge container passes through the plurality of molding holes separately and is molded to form a plurality of molding pieces, and these molding pieces are combined on the molding surface. By doing so, a modeled object is formed.
Here, since a diffusion chamber is provided between the mounting portion and the molding portion, it is possible to prevent the discharged material from concentrating on a specific part of the plurality of molded holes, and the discharged material is less likely to vary in each molded hole. Can be supplied. As a result, it is possible to prevent the discharged product from being excessively or excessively supplied to the molded holes, and to supply an appropriate amount of the discharged product to each molded hole. Therefore, it becomes possible to accurately form the modeled piece formed by each molded hole, and it is possible to form the modeled object with high accuracy.
In addition, since the diffusion chamber is provided with a regulating member, the regulating member can regulate the straight movement of the discharged material discharged from the discharge hole. As a result, the discharged material can be effectively diffused in the diffusion chamber.

The discharge hole is provided inside a stem erected so as to be movable downward in an upwardly urged state at the mouth of the discharge container, and the mounting portion may be mounted on the discharge hole via the stem. Good.

In this case, since the mounting portion is mounted in the discharge hole via the stem, by lowering the mounting portion, the stem can be lowered to discharge the discharged material from the discharge hole, and the discharged product can be simplified. Can be discharged to.

The mounting portion may be rotatably mounted on the stem about the axis of the stem and lowered as the stem is rotationally moved with respect to the stem.

In this case, since the mounting portion is lowered with the rotational movement with respect to the stem, the mounting portion can be lowered together with the stem by rotating the mounting portion with respect to the stem. This makes it easier to stabilize the movement amount and the movement speed when the mounting portion is lowered, as compared with the case where the mounting portion is pressed and lowered, for example. Therefore, it is possible to stabilize the discharge amount and the discharge speed of the discharged material discharged from the discharge hole. As a result, the discharged material can be effectively diffused in the diffusion chamber.

A conversion mechanism for converting the rotational movement of the mounting portion with respect to the stem into a descending motion of the mounting portion with respect to the mouth portion is further provided, and the conversion mechanism is used when the mounting portion rotates in the same direction around the axis. The descending state in which the mounting portion is lowered against the upward urging force of the stem and the rising state in which the mounting portion is raised by the upward urging force of the stem may be alternately repeated.

In this case, when the mounting portion rotates in the same direction around the axis, the conversion mechanism alternately repeats the descending state and the rising state, so that, for example, the mounting portion excessively lowers as the mounting portion rotates and moves. Can be suppressed. As a result, the discharged material can be diffused more effectively in the diffusion chamber.

Of the plurality of molding holes, at least a part is a molding slot formed in the shape of a slot, and as the molding slot, the direction in which the molding slot extends on the wall surface defining the molding slot. Of the pair of side wall surfaces extending along the above, one side wall surface may be provided with an inclined elongated hole that is inclined so as to be separated from the other side wall surface as it approaches the molding surface.

In this case, among the plurality of modeling pieces, the modeling piece formed by the forming slot is formed longer in the direction in which the forming slot extends.
Here, in the inclined slotted hole, one side wall surface is inclined as described above, so that the modeled piece formed by the inclined slotted hole among the plurality of modeling pieces may be erected straight on the modeling surface. Instead, it can be erected while being tilted in the direction in which one side wall surface is tilted. Therefore, it is possible to erect the modeled piece formed by the long hole while tilting it in a desired direction according to the shape of the modeled object, and the modeled object can be formed with high accuracy.

The formed elongated hole may extend in a circumferential direction orbiting around an axis orthogonal to the molding surface.

In this case, since the molding slot extends in the circumferential direction, for example, a molding piece such as a petal can be molded on the molding surface by the molding slot.

A plurality of the formed elongated holes may be arranged at intervals in the circumferential direction.

In this case, since a plurality of molding elongated holes are arranged at intervals in the circumferential direction, a plurality of molding pieces such as petals can be arranged side by side in the circumferential direction on the molding surface. Thereby, for example, it is possible to make it easy to accurately shape the corolla by the whole of these plurality of modeling pieces.

A plurality of the molded elongated holes may be arranged at intervals in the radial direction along the molding surface.

In this case, since a plurality of molding elongated holes are arranged at intervals in the radial direction, it is possible to arrange a plurality of molding pieces such as petals on the molding surface in the radial direction. As a result, it is possible to facilitate high-precision modeling of so-called double-flowered flowers such as roses.

As the inclined elongated hole, an outer inclined elongated hole in which the side wall surface located on the outer side in the radial direction of the pair of side wall surfaces is inclined is provided, and among the plurality of molded elongated holes, the outermost portion in the radial direction is provided. The one located at may be the outer inclined elongated hole.

In this case, of the plurality of molded elongated holes, the one located on the outermost side in the radial direction is the outward inclined elongated hole, so that the portion located on the outer side in the radial direction on the modeling surface is molded by the molded elongated hole. The model piece can be erected while being tilted outward in the radial direction. As a result, for example, in a double-flowered flower, it is possible to direct a shaped piece corresponding to a petal located on the outer periphery toward the outside in the radial direction, and it is possible to accurately shape a shaped object such as a flower. ..

The size of the diffusion chamber along the head axis direction may be 1.5 mm or more.

In this case, since the size of the diffusion chamber along the head axis direction is 1.5 mm or more, a sufficient size (height) along the head axis direction of the diffusion chamber can be sufficiently secured. This makes it possible to effectively diffuse the discharged material in the radial direction. For example, the discharged material is allowed to pass through the outermost molding hole in the radial direction among the plurality of molding holes for molding. The piece can be easily modeled.

Of the plurality of molded holes, at least a part thereof is a formed elongated hole formed in an elongated hole shape, and a plurality of the formed elongated holes may be arranged at intervals in the radial direction.

In this case, since a plurality of molding elongated holes are arranged at intervals in the radial direction, it is possible to arrange a plurality of molding pieces such as petals on the molding surface in the radial direction. As a result, it is possible to facilitate high-precision modeling of so-called double-flowered flowers such as roses.

Of the plurality of formed elongated holes, the width at the lower end opening of the formed elongated hole located on the innermost side in the radial direction may be less than 2 mm.

In this case, the width of the lower end opening of the formed slot located on the innermost side in the radial direction among the plurality of molded slot is less than 2 mm, and this width can be maintained narrow. Therefore, when the discharged material is discharged from the discharge hole inside the radial direction, the discharged material in the diffusion chamber passes through the innermost forming elongated hole in the radial direction among the plurality of forming elongated holes. Can be suppressed. As a result, the discharged material can be easily diffused effectively toward the outside in the radial direction in the diffusion chamber.

The radial distance between the formed elongated holes adjacent to each other in the radial direction may be less than 5 mm.

In this case, since the distance between the formed elongated holes adjacent to each other in the radial direction is less than 5 mm in the radial direction, the formed elongated holes can be appropriately densely packed. As a result, it is possible to prevent the modeling pieces from being excessively separated from each other on the modeling surface, and it is possible to easily combine a plurality of modeling pieces with high accuracy on the modeling surface.

According to the present invention, a modeled object can be formed with high accuracy.

The second conversion unit 37 is closed from above by a peripheral wall surface 38 that extends over the entire length in the circumferential direction and faces downward.

As shown in FIG. 6, the peripheral wall surface 38 is divided into a plurality of divided walls 39 in the circumferential direction. Each dividing wall 39 is recessed toward the upper side. The dividing walls 39 are formed to have the same shape and the same size as each other. A plurality of the dividing walls 39 are provided in the circumferential direction, and in the illustrated example, the same number of three as the first conversion unit 36 are continuously provided. The divided wall 39 includes a base wall portion 40, a regulation wall portion 41, and a guide wall portion 42.

The regulation wall portion 41 extends downward from one end of the base wall portion 40 in the circumferential direction and faces the other side in the circumferential direction. The regulation wall portion 41 extends straight in the head shaft O2 direction. The guide wall portion 42 extends downward from the other end of the base wall portion 40 in the circumferential direction and faces one side in the circumferential direction. The guide wall portion 42 gradually extends from the upper side toward the lower side toward the other side in the circumferential direction.

The conversion mechanism 35 regulates the rotational movement of the mounting portion 21 toward the stem 16 in the circumferential direction while restricting the rotational movement of the mounting portion 21 toward the stem 16 in the circumferential direction. The conversion mechanism 35 converts the rotational movement of the mounting portion 21 with respect to the stem 16 toward the other side in the circumferential direction into a descending motion of the mounting portion 21 with respect to the mouth portion 12.

In the conversion mechanism 35, in the initial state before the operation, the first conversion unit 36 is in close proximity to or in contact with the base wall portion 40 of the division wall 39 from below.
When the mounting portion 21 rotates toward one side in the circumferential direction from the initial state, the first conversion portion 36 abuts on the regulation wall portion 41, so that further rotational movement of the mounting portion 21 is restricted.

On the other hand, when the mounting portion 21 rotates toward the other side in the circumferential direction from the initial state, the first conversion portion 36 slides on the guide wall portion 42 in the circumferential direction. At this time, the first conversion unit 36 is guided downward by the guide wall portion 42, so that the mounting portion 21 gradually moves downward against the upward urging force of the stem 16. When the first conversion unit 36 reaches the lower end of the guide wall portion 42, the first conversion unit 36 gets over the guide wall portion 42 on the other side in the circumferential direction. Then, the mounting portion 21 is raised along the regulation wall portion 41 by the upward urging force of the stem 16, and the first conversion portion 36 again approaches or comes into contact with the base wall portion 40 of the split wall 39 from below.

As described above, when the mounting portion 21 rotates toward the other side in the circumferential direction (the same direction around the axis of the stem), the conversion mechanism 35 moves the mounting portion 21 against the upward urging force of the stem 16. The descending state of lowering and the ascending state of raising the mounting portion 21 by the upward urging force of the stem 16 are alternately repeated.

In the present embodiment, among the plurality of hole rows 54, the molded elongated holes 53 forming the outer hole row 54a located on the outer side in the radial direction are all outer inclined elongated holes 56, and are located on the inner side in the radial direction. The formed elongated holes 53 forming the hole row 54b are all straight elongated holes 55, and the formed elongated holes 53 forming the middle hole row 54c located between the outer hole row 54a and the inner hole row 54b are all inside. It is said to be an inclined elongated hole 57.

By the way, in the present embodiment, the widths of the lower end openings of the plurality of molded long holes 53 are equal to each other, while the widths of the upper end openings of the formed long holes 53 are diameters from the formed long holes 53 located inside in the radial direction. The size is gradually increased toward the formed slot 53 located outside in the direction. For example, when the first forming slot 53 and the second forming slot 53 are arranged in order from the inside to the outside in the radial direction, the width at the upper end opening of the second forming slot 53 is the second. It is equal to or larger than the width at the upper end opening of the molded slot 53 of 1. The width of the upper end opening of the formed elongated hole 53 may be different for each position along the circumferential direction (the direction in which the formed elongated hole 53 extends). In this case, the maximum width of the formed elongated hole 53 at the upper end opening is determined. It is preferable that the size gradually increases from the forming slot 53 located inside in the radial direction to the forming slot 53 located outside in the radial direction.

As described above, in the present embodiment, the width of the straight elongated holes 55 is about 0.4 to 1.0 mm, and all the molded elongated holes 53 forming the inner hole row 54b are the straight elongated holes 55. As a result, the width of the lower end opening of the forming slot 53 located on the innermost side in the radial direction among the plurality of molding holes 53 is less than 2 mm, for example, within a moldable range. It is provided small. When the width of the lower end opening of the forming slot 53 located on the innermost side of the plurality of molding holes 53 is different for each position along the circumferential direction (direction in which the molding hole 53 extends). The maximum width of the formed slot 53 at the lower end opening is preferably less than 2 mm.

Next, the operation of the modeling head 20 as shown in FIG. 1 will be described.

In the modeling head 20, first, the stem 16 is lowered in order to discharge the discharged material M from the discharge hole 11. At this time, by rotating the modeling portion 23 relative to the discharge container 10, the mounting portion 21 is rotated around the head shaft O2 with respect to the stem 16 via the modeling portion 23. Then, the rotational movement of the mounting portion 21 is converted into a descending motion of the mounting portion 21 by the conversion mechanism 35, and the mounting portion 21 narrows the allowable gap S in the head shaft O2 direction and together with the stem 16 the mouth portion of the discharge container 10. It descends against 12. As a result, the discharged material M is discharged from the discharge hole 11 in the stem 16.

The discharged material M discharged from the discharge hole 11 is supplied into the diffusion chamber 50 through the communication hole 26 and the bridge portion 52 adjacent to each other in the circumferential direction while its linear movement is regulated by the regulating member 51. The discharged material M supplied into the diffusion chamber 50 diffuses in the radial direction and is supplied from the supply surface 49 to the plurality of molding holes 47. Since the size of the diffusion chamber 50 in the head axis O2 direction is 1.0 mm or more as in the present embodiment, the discharged material M can be effectively diffused in the radial direction, and moreover, it is diffused. When the size of the chamber 50 in the head axis O2 direction is 1.5 mm or more, the discharged material M can be more effectively diffused in the radial direction.

When the discharged material M passes through the plurality of molding holes 47 separately and is molded, as shown in FIG. 9, a plurality of molding pieces A1 are formed, and these molding pieces A1 are combined on the molding surface 48. As a result, the model A is formed. The molding piece A1 formed by the forming elongated hole 53 is formed longer in the direction in which the forming elongated hole 53 extends.

As described above, according to the molding head 20 according to the present embodiment, as shown in FIG. 1, since the diffusion chamber 50 is provided between the mounting portion 21 and the molding portion 23, a plurality of molding holes are formed. It is possible to prevent the discharged material M from concentrating on a specific part of the 47, and to supply the discharged material M to each molding hole 47 with little variation. As a result, it is possible to suppress the discharge M from being excessively or excessively supplied to the molding holes 47, and to supply an appropriate amount of the discharge M to each molding hole 47. Therefore, the model piece A1 formed by each of the molding holes 47 can be formed with high accuracy, and the modeled object A can be formed with high accuracy.
Further, in the present embodiment, since the size of the diffusion chamber 50 along the head shaft O2 direction is 1.5 mm or more, a sufficient size (height) along the head shaft O2 direction of the diffusion chamber 50 can be sufficiently secured. .. This makes it possible to effectively diffuse the discharged material M in the radial direction. For example, the discharged material M is allowed to pass through the outermost molding hole 47 in the radial direction among the plurality of molding holes 47. The modeling piece A1 can be easily modeled.

Further, since the regulating member 51 is provided in the diffusion chamber 50, the regulating member 51 can regulate the straight movement of the discharged material M discharged from the discharge hole 11. As a result, the discharged material M can be effectively diffused in the diffusion chamber 50.

Further, since the mounting portion 21 is mounted on the discharge hole 11 via the stem 16, the stem 16 can be lowered by lowering the mounting portion 21, and the discharged material M can be discharged from the discharge hole 11. The discharged material M can be easily discharged.

Further, since the mounting portion 21 is lowered with the rotational movement with respect to the stem 16, the mounting portion 21 can be lowered together with the stem 16 by rotating the mounting portion 21 with respect to the stem 16. As a result, it is possible to make it easier to stabilize the moving amount and moving speed when the mounting portion 21 is lowered, as compared with the case where the mounting portion 21 is pressed and lowered, for example. Therefore, the discharge amount and the discharge speed of the discharged material M discharged from the discharge hole 11 can be stabilized. As a result, the discharged material M can be effectively diffused in the diffusion chamber 50.

Further, when the mounting portion 21 rotates to the other side in the circumferential direction, the conversion mechanism 35 alternately repeats the descending state and the rising state. Therefore, for example, the mounting portion 21 becomes excessive as the mounting portion 21 rotates. It is possible to suppress the descent. As a result, the discharged material M can be diffused more effectively in the diffusion chamber 50.

Further, as shown in FIG. 9, since the molding slot 53 extends in the circumferential direction, for example, the molding piece A1 like a petal can be molded on the molding surface 48 by the molding slot 53. it can.
Further, since a plurality of molding elongated holes 53 are arranged at intervals in the circumferential direction, a plurality of molding pieces A1 such as petals can be arranged side by side in the circumferential direction on the molding surface 48. Thereby, for example, the corolla can be easily shaped with high accuracy by the whole of these plurality of modeling pieces A1.
Moreover, since a plurality of molded elongated holes 53 are arranged at intervals in the radial direction, the molding pieces A1 such as petals can be arranged in a plurality in the radial direction on the molding surface 48. As a result, it is possible to facilitate high-precision modeling of so-called double-flowered flowers such as roses.

Here, in the inclined elongated holes 56 and 57, since one side wall surface 58 is inclined as described above, the modeling piece A1 formed by the inclined elongated holes 56 and 57 is modeled among the plurality of modeling pieces A1. Rather than standing straight on the surface 48, one side wall surface 58 can be erected while being tilted in the direction of inclination. Therefore, the model piece A1 formed by the formed slot 53 can be erected while being tilted in a desired direction according to the shape of the model A, and the model A can be formed with high accuracy. ..

Of the plurality of molded elongated holes 53, the one located on the outermost side in the radial direction is the outer inclined elongated hole 56, so that the portion located on the molding surface 48 on the outer side in the radial direction is formed by the formed elongated hole 53. The molding piece A1 can be erected while being tilted outward in the radial direction. As a result, for example, in a double-flowered flower, the modeling piece A1 corresponding to the petals located on the outer periphery can be directed outward in the radial direction, and the modeling object A such as a flower can be accurately modeled. it can.

In the present embodiment, all the molded elongated holes 53 provided in the outer hole row 54a are designated as outer inclined elongated holes 56, and all the molded elongated holes 53 provided in the inner hole row 54b are designated as straight elongated holes 55. The formed elongated holes 53 provided in the middle hole row 54c are all inwardly inclined elongated holes 57. Therefore, while the modeling piece A1 formed on the outer peripheral portion in the radial direction on the modeling surface 48 is erected while being tilted outward in the radial direction, the modeling piece formed in the central portion in the radial direction on the modeling surface 48. A1 can be densely packed inward in the radial direction. As a result, for example, it is possible to facilitate the modeling of double-flowered flowers with higher accuracy.

Further, among the plurality of formed elongated holes 53, the width at the lower end opening of the formed elongated hole 53 located on the innermost side in the radial direction is less than 2 mm, and this width can be maintained narrow. Therefore, when the discharged material M is discharged from the discharge hole 11 inside in the radial direction, the discharged material M in the diffusion chamber 50 has a molding length located on the innermost side of the plurality of molding elongated holes 53 in the radial direction. It is possible to suppress the passage through the hole 53. This makes it possible to effectively diffuse the discharged material M in the diffusion chamber 50 toward the outside in the radial direction.

Further, since the radial distance between the formed elongated holes 53 adjacent to each other in the radial direction is less than 5 mm, the formed elongated holes 53 can be appropriately densely packed with each other. As a result, it is possible to prevent the modeling pieces A1 from being excessively separated from each other on the modeling surface 48, and it is possible to easily combine the plurality of modeling pieces A1 with high accuracy on the modeling surface 48.
In the present embodiment, the radial distance between the forming elongated holes 53 adjacent to each other in the radial direction gradually increases from the inside to the outside in the radial direction, so that the forming elongated holes located on the outer side in the radial direction are gradually increased. The molding piece A1 formed in 53 can be easily opened wide toward the outside in the radial direction.

Further, in the present embodiment, the width of the upper end opening of the forming slot 53 is gradually increased from the forming slot 53 located inside in the radial direction to the molding slot 53 located outside in the radial direction. .. As a result, the molding piece A1 formed by the molding slot 53 can be gradually formed larger from the inside to the outside in the radial direction.

Then, the mounting portion 21 descends with respect to the mouth portion 12 of the discharge container 10 together with the stem 16 while narrowing the allowable gap S in the head shaft O2 direction. As a result, the discharged material M is discharged from the discharge hole 11 in the stem 16. When the bottom wall portion of the mounting portion 21 comes into contact with the top wall portion of the auxiliary portion 22 by narrowing the allowable gap S, the lowering of the mounting portion 21 is restricted.
When the discharge of the discharged material M from the discharge hole 11 is stopped, the pressing of the modeling unit 23 is released. Then, the mounting portion 21 and the modeling portion 23 are raised by the upward urging force of the stem 16.
