Description

  The present invention relates to a honeycomb structure manufacturing method and a honeycomb structure manufacturing system for manufacturing a honeycomb structure used as an artificial nest spleen for beekeeping by rapid prototyping.

<First prior art>
As a first conventional technique of an artificial nest spleen used for beekeeping, there is Patent Document 1 “Beekeeping nest foundation and beekeeping method”. In the artificial nest spleen of this document, the body part and the frame part are formed by integrally molding using polycarbonate as a resin material, and the back side of the single frame constituting the bottom part of each cell is directed to the center point of each cell. Inclined downward and the back surface of each frame is formed into a symmetrical V-shaped cross section.

  Further, the bottom of the cell is formed as a thin nectar film by solidifying the melted beeswax, and the larvae communicate with each other through stimuli such as sound, vibration, and heat to promote growth.

  Furthermore, when the distance between the centers of the cells is changed to create a worker beehive foundation and a beehive foundation, when the bees are no longer needed or when ticks are concentrated on the beehive foundation, The nest foundation is configured to be removed from the nest box.

<Second prior art>
As a second conventional technique of an artificial nest spleen used for beekeeping, there is Patent Document 2 “Artificial nest spleen”. In the artificial nest spleen disclosed in this document, at least a pair of facing partition walls among the six-surface partition walls of each cell in which the bottom plate and partition walls are formed of polylactic acid resin are expanded from the bottom of the partition toward the opening. Inclined to.

  With this configuration, a sufficient space in each cell is secured, the bee is devised so as to be smooth, and the mold release from the mold is improved during molding.

  In addition, each cell is configured to tilt upward while the artificial nest spleen is suspended from the nest box, thereby preventing honey accumulated in each cell from flowing out of the cell.

  Furthermore, since the strength after molding is sufficient, a member such as a metal wire that reinforces the mechanical strength is not required, and the used artificial nest spleen can be buried in the ground as it is and discarded.

  Furthermore, since the height of the partition wall is set appropriately from the beginning, it is not necessary for the bees to create the partition wall, and honey accumulation can be started immediately, thereby improving the production efficiency of honey.

<Third prior art>
As a third conventional technique for an artificial nest spleen used for beekeeping, there is Patent Document 3 “An artificial nest for bees”. The artificial nest spleen in this document uses a sheet obtained by processing an aluminide fiber into a sheet shape, and a thermosetting resin is attached and impregnated on the outer surface of the cell wall.

  Further, the height of the cell wall surface is set to about 7 mm, and the remaining bees are added to the wall of about 3 mm to finally form a wall surface having a height of about 10 mm. This manufacturing method is said to reduce the labor of bees making the wall and improve the production efficiency of honey.

  Further, the artificial nest spleen of this document is manufactured by a stretching method in which an adhesive is applied to a sheet-like material on a line, and then a plurality of sheets are bonded by heating and pressurizing, and then stretched in the stacking direction.

<Fourth prior art>
As a fourth conventional technique of an artificial nest spleen used for beekeeping, there is Patent Document 4 “Paper beehive of bee for pollination”. The artificial nest spleen described in this document is formed by laminating both sides of a paper partition using a paper honeycomb core or roll core, and applying or impregnating beeswax to the whole.

  Thus, by forming a nest hole as a base when the bees start nest building in advance, the time required for nest building is shortened and the production efficiency of honey is improved.

  Moreover, since the raw material is paper, it is lightweight, and can be easily performed by incineration as a disposal.

<Fifth prior art>
As a fifth conventional technique of an artificial nest spleen used for beekeeping, there is Patent Document 5 “Portable field-installed bee breeder and beehive”. The artificial nest spleen in this document is configured by forming a cavity having a hexagonal cross section in a grid pattern by sequentially laminating corrugated sheets as described in FIG. 2 or FIG. To do. As an example, these corrugated sheets are made of biodegradable cardboard with beeswax and can be easily disposed of, and are devised to be resistant by waterproofing.

<Sixth Prior Art>
Although not a conventional technique for an artificial nest spleen used for beekeeping, Patent Document 6 describes a “honeycomb core manufacturing method” that forms the basic structure of a honeycomb structure and a honeycomb structure manufacturing method. In this publication, flat sections of a plurality of prepreg sheets based on fiber-reinforced thermoplastic resin are brought into contact with each other and heat-bonded to form a longitudinal cross-sectional shape into a honeycomb shape. Thereafter, the laminated prepreg sheets are cut at predetermined lengths to produce a honeycomb core having a desired thickness.

<Seventh prior art>
Further, the manufacturing technique by the honeycomb core extending method is described in FIG.

<Eighth prior art>
The bee ecosystem based on the latest research is described in detail in Non-Patent Document 1.

<Ninth Prior Art>
Recently, a so-called 3D printer that produces slice data obtained by slicing a cross section in the stacking direction from three-dimensional data of a three-dimensional structure and manufactures a three-dimensional structure using resin, metal, gypsum, or the like has attracted attention. In order to increase the strength of the structure and reduce the weight when creating a three-dimensional structure with a 3D printer, a technique for laminating the inside of the structure with a regular hexagonal honeycomb structure has been developed.

  As such a technique, there is Patent Document 8 “3D modeling apparatus and 3D modeling method”. 4 and 6 of this document disclose a three-dimensional structure formed by sequentially laminating honeycomb structures inside the structure.

<Tenth prior art>
The 10th prior art which models a modeling thing which has a honeycomb structure inside using a 3D printer is indicated by patent documents 9 "a method and an apparatus which form a three-dimensional object." In [0106] of this document, it is described that hexagons are excellent in that the tiles can be densely packed, and further, in [0107], when the layers by the tiled pattern are sequentially formed, each layer is described. Describes that the tile positions are staggered so that tiles in adjacent layers are not aligned with each other.

<Eleventh prior art>
The eleventh prior art for modeling a modeled object having a honeycomb structure inside using a 3D printer is disclosed in Patent Document 10 “High-Speed Prototype Device for Three-dimensional Object with Support Structure”. [0145] of this document also describes that the inside of a modeled object is laminated in a honeycomb shape to reduce the weight of the modeled object as a whole, reduce the modeling material, shorten the manufacturing time, and prevent cracks.

  Patent Document 1 “Beek-keeping nest foundation and beekeeping method” is designed to form the bottom of each cell as thin as possible and promote the growth of larvae, so that the back side of the frame constituting the cell bottom is the center point of each cell. The back surface of each frame is formed in a symmetrical V-shaped cross section. In addition, a technique is disclosed in which the bottom of the cell is solidified with molten beeswax to form a thin film.

  However, as described in [0018], the manufacturing method of this document uses a method of integrally molding with a mold using polycarbonate as a resin material. In this method, a honeycomb structure suitable for bee colonies is used. It is not easy to produce a nest spleen with a body.

  That is, as described in Non-Patent Document 1, bee colonies have a complex tissue form, and bees act in a high behavior pattern in order to adapt to the environment. The nest spleen production method described in this document is suitable for uniform mass production, but has various variations suitable for bee colonies and has a highly complex structure. It is difficult.

  Patent Document 2 “Artificial Nest Spleen” uses a general injection molding as a manufacturing method as described in [0033]. For this reason, as described above, it is difficult to manufacture a nest spleen suitable for bee colonies in a timely manner.

  In other words, although the method for producing an artificial nest spleen by injection molding is excellent in terms of mass productivity, there are problems in flexibility for redesign and rapid processing from design to production. For this reason, it is difficult to make an artificial nest spleen experimentally by changing many environmental variables and to timely manufacture an artificial nest spleen most suitable for a wide variety of colonies.

  Patent Document 3 “artificial nest for bees” is manufactured by a stretching method in which a sheet-like material is coated with an adhesive on a line, and then a plurality of sheets are heated and pressed to be bonded and stretched in the stacking direction. Yes. For this reason, as described above, it is difficult to proceed with the flexibility from the redesign and from the design to the production promptly.

  In other words, the artificial nest spleen suitable for the natural environment and the bee colony is carefully observed to obtain appropriate design parameters, and the artificial nest spleen is quickly prototyped based on these design parameters. It is difficult to develop an optimal artificial nest spleen by testing in the field whether it is suitable for the environment and bee colonies.

  Specifically, as described in [0024], the nest spleen mounted on Patent Document 4 “Panel beehive paper beehive for pollination” includes a paper honeycomb core and both sides of a paper partition made of kraft paper. It is formed by impregnating with beeswax after being attached to. In the fourth prior art manufacturing method, as described above, it is difficult to flexibly improve the redesign and to efficiently advance the process from design to manufacturing. Similarly, there is no description or suggestion of developing a nest spleen that accommodates various variations suitable for a wide variety of bee colonies and has a highly complex structure.

  Patent Document 5 “Portable Field-Installed Bee Breeder and Beehive” is manufactured by sequentially stacking folded corrugated sheets to form a hexagonal or other cross section in a grid pattern. Therefore, as described above, although the technique of this document is suitable for producing a uniform and mass-produced nest spleen, it corresponds to various variations suitable for a wide variety of bee colonies, and It is difficult to develop a nest spleen with a highly complex structure.

  In Patent Document 6 “Honeycomb Core Manufacturing Method”, flat portions of a plurality of prepreg sheets are brought into contact with each other and thermally fused to form a longitudinal cross-sectional shape into a honeycomb shape. This method is suitable for mass production of honeycomb cores of the same structure in large quantities on the production line, but as mentioned above, it is compatible with various variations suitable for a wide variety of bee colonies and is highly complex. It is unsuitable to quickly develop a nest spleen having a unique structure and to flexibly respond to design changes.

  FIG. 4 of Patent Document 7 describes a method for forming a three-dimensional honeycomb core by stretching a commonly used honeycomb core on a flat plate. As described above, the honeycomb structure has various variations and has a highly complex structure, although it is convenient for manufacturing a large number of solid honeycombs with a constant shape for the purpose of core material It is unsuitable to develop a body quickly or to develop a honeycomb structure flexibly in response to a design change.

  Chapter 7 of Non-Patent Document 1 describes in detail a natural nest made of bees, but needless to say, there is no description or suggestion about an artificial nest spleen.

  FIG. 6 of Patent Document 8 describes a honeycomb structure formed by laminating a photocurable resin by an inkjet method. In this document, in order to improve the strength in the stacking direction, in the portion constituting the skeleton, the modeling material is laminated in a state where tackiness is lost to ensure the rigidity of the skeleton portion, while in the portion of the modeled object, the tack is The modeling material is laminated in a state where the properties remain, and the bonding strength in the laminating direction is improved. Using such a manufacturing method, even when a trophy or the like is accidentally dropped, it is prevented from being broken and broken from the interface portion to be laminated.

  That is, the purpose of this document is to improve the mechanical strength of the shaped object by making the inside of the shaped object a honeycomb structure, but there is no description at all about the honeycomb structure and the honeycomb structure manufacturing method suitable for the honeycomb spleen. Not. For example, the thickness of the bottom wall constituting the nest spleen is desired to be as thin as possible. However, it is an advanced technology to stably manufacture an artificial nest spleen by integrating this thin sheet-like structure with the honeycomb structure. is necessary. On the other hand, the honeycomb structure of this document does not have the concept of “bottom wall”, and is merely a structure that merely maintains mechanical strength.

  The purpose of Patent Document 9 “Method and apparatus for forming a three-dimensional object” is to improve the structural integrity of parts formed by stereolithography and reduce distortion, as described in [0009]. The honeycomb structure and the honeycomb structure manufacturing method suitable for the honeycomb spleen as described above are not described at all.

  Patent Document 10 “High-Speed Prototyping Device for 3D Object with Support Structure” uses a smoothing member (rotating cylinder) to thicken a flowable material supplied on a material supply stand in an SDM (Selective Deposition Modeling) system. Although the accuracy of the shaped object is improved by controlling it to be constant, the above-described honeycomb structure suitable for the honeycomb spleen and the honeycomb structure manufacturing method are not described at all.

  Moreover, when forming the bottom wall which has an inclination angle, it is necessary to use a support material different from a modeling material, but there is no description about the removal of the support material required by post-processing. That is, each cell of the nest spleen is independent from each other, and it is not easy to completely remove the support material attached to the cell side wall of each cell. If the support material cannot be completely removed and remains in the nest spleen, an unpleasant odor and stickiness peculiar to the support material are generated, which is not preferable for bees.

  An object of the present invention is to provide a honeycomb structure manufacturing method and a honeycomb structure manufacturing system in which the above problems are preferably solved.

  A method for manufacturing a honeycomb structure according to the present invention includes a honeycomb structure for beekeeping having a plurality of cells each having a hexagonal cell bottom wall and six cell side walls erected on each side of the cell bottom wall. In a honeycomb structure manufacturing method for manufacturing a body, the first step of inputting the three-dimensional data of the honeycomb structure and converting the three-dimensional data into slice data, and the slice data converted in the first step are referred to Then, the cell bottom wall is formed in a hexagonal pyramid shape protruding backward by laminating the modeling material and the support material of the material different from the modeling material on the modeling stage, respectively, and the cell side walls are all on the same side. And a third step of removing the support material from the honeycomb structure formed in the second step. It is obtained by way.

  The method for manufacturing a honeycomb structure according to the present invention forms a base having an inclined surface on a modeling stage with a support material, and forms a cell bottom wall on the inclined surface with a predetermined thickness substantially perpendicular to the inclined surface. It is formed by laminating materials.

  In the honeycomb structure manufacturing method according to the present invention, after the third step, the entire cell opening of the honeycomb structure from which the support material has been removed is covered with the cell sealing means, and the honeycomb structure is washed in this state. A fourth step is provided.

  In the honeycomb structure manufacturing method according to the present invention, in the first step, the unique information of the cell side walls of each cell provided in the honeycomb structure is encoded along a direction parallel or perpendicular to each cell side wall in plan view. In the second step, cell side walls that match predetermined specific information are formed according to the result of encoding.

  The honeycomb structure manufacturing method according to the present invention is such that the upper end of the cell side wall is larger than the thickness of the cell side wall.

  The method for manufacturing a honeycomb structure according to the present invention includes a cell reinforcing portion that reinforces the coupling between the cell bottom wall and the cell side wall along the cell corner portion where the cell bottom wall and the cell side wall contact each other or discretely. It is a thing.

  The method for manufacturing a honeycomb structure according to the present invention is such that a sub-honeycomb structure including a plurality of cells larger than the cells is disposed on at least a part of the outer peripheral portion of the honeycomb structure.

  In the honeycomb structure manufacturing system according to the present invention, the honeycomb structure manufactured by the honeycomb structure manufacturing method according to any one of claims 1 to 7 is mounted as an artificial spleen for beekeeping. The nest box provided with the environmental parameter measuring means for measuring the environmental parameters related to the honeycomb structure, and the environmental parameters measured by the environmental parameter measuring means are obtained, and the honeycomb structure is subjected to the activity of the bees and the honey stored by the bees. The correlation with the amount is simulated, and based on the simulation result, the honeycomb structure material and the structural parameters are corrected, and the honeycomb structure design apparatus for correcting the three-dimensional data of the honeycomb structure is provided. Is.

  According to the present invention, to produce a honeycomb structure for beekeeping having a plurality of cells each having a hexagonal cell bottom wall and six cell side walls erected on each side of the cell bottom wall. In the honeycomb structure manufacturing method, the first step of inputting the three-dimensional data of the honeycomb structure, converting the three-dimensional data into slice data, and referring to the slice data converted in the first step, By laminating support materials of materials different from the modeling material on the modeling stage, the cell bottom wall is formed in a hexagonal pyramid shape protruding backward, and the cell side walls are inclined so that all the cells are all on the same side. And a third step of removing the support material from the honeycomb structure formed in the second step. Without using any other special manufacturing equipment, 3D data is referenced, and a honeycomb structure is manufactured by curing a molding material such as resin, so there are various variations and highly complex structures. The honeycomb structure can be easily and quickly manufactured, and the manufacturing cost can be reduced. For design changes, the structure and dimensions of the honeycomb structure are corrected on the three-dimensional CAD tool, and the three-dimensional structure forming device forms the honeycomb structure with reference to this data, so that the design change can be made flexibly. The effect that a corresponding honeycomb structure can be manufactured is obtained. Furthermore, by stacking modeling material on the support material, the hexagonal pyramid shaped cell bottom wall protruding backward can be formed thinly, and it is suitable for bees when the honeycomb structure is mounted on the nest box as an artificial nest spleen An effect of providing a comfortable environment. Furthermore, since the cell bottom wall has a hexagonal pyramid shape protruding rearward and the cell bottom wall can be formed thin, an effect that can provide an environment suitable for the growth of bees, particularly larvae, can be obtained. In particular, when manufactured by an ink jet method or an optical modeling method, the cell bottom wall can be made sufficiently thin and stably manufactured.

  According to this invention, the base having an inclined surface is formed on the modeling stage by the support material, and the cell bottom wall is laminated with the modeling material with a predetermined thickness on the inclined surface substantially perpendicular to the inclined surface. Since it is formed, even if the cell bottom wall is extremely thin, the effect that the cell bottom wall can be stably stacked can be obtained.

  According to this invention, after the third step, the entire cell opening of the honeycomb structure from which the support material has been removed is covered with the cell sealing means, and the fourth step of cleaning the honeycomb structure in this state is performed. Since the support material residue that could not be completely removed in the third step can be prevented from entering the cell internal space from the cell opening, the support used when forming the cell bottom wall is provided. The material does not adhere to the cell side walls of the internal space of each cell as the cleaning liquid is agitated, and it is possible to produce a clean honeycomb structure that does not have the odor and stickiness peculiar to the support material, which is preferable for bees. The effect that an artificial nest spleen can be provided is obtained.

  According to the present invention, in the first step, three-dimensional data is encoded by encoding the unique information of the cell sidewalls of each cell included in the honeycomb structure along a direction parallel or perpendicular to each cell sidewall in plan view. In the second step, cell side walls that match predetermined specific information are formed according to the result of encoding, so that it is modeled by the three-dimensional model forming apparatus. In addition, there is an effect that a universal coding method can be provided for the honeycomb structure.

  According to the present invention, since the upper end of the cell side wall is larger than the thickness of the cell side wall, the bees can easily walk around the edge of the upper end of the cell, and the signals when the bees vibrate to communicate with the friends. Transmission can be performed efficiently, and an effect of providing an artificial nest spleen in which honey stored in the cell internal space does not leak out by the edge can be obtained.

  The method for manufacturing a honeycomb structure according to the present invention includes a cell reinforcing portion that reinforces the coupling between the cell bottom wall and the cell side wall along the cell corner portion where the cell bottom wall and the cell side wall contact each other or discretely. As a result, the strength of the cell can be increased, and an effect that a highly reliable honeycomb structure can be manufactured can be obtained.

  In the honeycomb structure manufacturing method according to the present invention, the sub-honeycomb structure including a plurality of cells larger than the cells is arranged at least at a part of the outer peripheral portion of the honeycomb structure. The honeycomb structure can be used as a male nest spleen that is necessary only during the breeding season, and each sub-honeycomb structure can be used to construct an artificial nest spleen that integrates these sub-honeycomb structures. There is no need to make a nest spleen, and the effect of further improving the production efficiency of honey is obtained.

  According to this invention, the honeycomb structure manufactured by the honeycomb structure manufacturing method according to any one of claims 1 to 7 is mounted as a beehive artificial spleen and relates to the honeycomb structure. The nest box provided with the environmental parameter measuring means for measuring the environmental parameters, and the environmental parameters measured by the environmental parameter measuring means are obtained, and the honeycomb structure is correlated with the activity of the bees and the amount of the honey stored by the bees. And based on the simulation results, the honeycomb structure material and the structural parameters are corrected, and the honeycomb structure design apparatus for correcting the three-dimensional data of the honeycomb structure is provided. It is actually tested whether it is suitable for bee colonies, and 24 hours rear using environmental parameter measuring means. By observing the behavior of the bees in the nest box in time, an appropriate structural parameter can be obtained, and this structural parameter can be quickly fed back to the improvement of the honeycomb structure, so that the honeycomb structure suitable for the bees can be improved. can get.

  As a device for forming a three-dimensional three-dimensional object, a so-called 3D printer (three-dimensional object forming device) has been rapidly spreading recently. As a manufacturing method using this 3D printer, various methods such as a hot melt laminating method, an optical modeling method, an ink jet method, and a powder sintering method have been developed and applied to a wide range of three-dimensional modeling objects.

  On the other hand, although there are mass-produced artificial nest spleens for bees, it cannot be said that artificial nest spleens suitable for bees are provided in various environments including the natural environment. is there.

  We invented the technical features and possibilities of the 3D printer and the necessary elements for the artificial nest spleen. Using the 3D printer, the artificial nest spleen with high honey production efficiency and high flexibility Found a way to develop.

  Hereinafter, embodiments of a honeycomb structure and a honeycomb structure manufacturing method according to the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 is a side cross-sectional view showing the configuration of a 3D printer used in the honeycomb structure manufacturing method according to Embodiment 1 of the present invention. Here, as an example, a 3D printer using an ink jet method is shown, but other three-dimensional model forming apparatus, for example, a 3D printer using an optical modeling method may be used.

  The 3D printer shown in FIG. 1 supplies a modeling material 12 and a support material 13 on the modeling stage 11 while scanning in the X-axis direction and the Y-axis direction, and sequentially stacks these materials 12 and 13. Have Here, the head 10 includes a modeling material supply head 101 that selectively supplies the modeling material 12 to the modeling stage 11 sequentially and sequentially according to a signal from a control unit (not shown), which is cured by the light from the light source 104. . A plurality of discharge nozzles (not shown) arranged in a line are provided at the tip of the modeling material supply head 101, and droplets of the modeling material 12 are discharged from these discharge nozzles.

  In the above description, the modeling material 12 that is cured by light, such as an ultraviolet curable resin, is used. However, a resin that is cured by a stimulus such as heat, electron beam, or vibration may be used.

  Further, the head 10 in FIG. 1 selectively places a polyvinyl alcohol (Poly Vinyl Alcohol, abbreviated as PVA) or a water-soluble support material 13 lower than the melting point of the modeling material 12 on the modeling stage 11 by a signal from the control unit. A support material supply head 102 for sequentially supplying is provided.

  The smooth roller 103 controls the thickness along the Z-axis direction of the modeling material 12 discharged from the modeling material supply head 101 and the support material 13 discharged from the support material supply head 102. That is, the thickness of the modeling material 12 and the support material 13 discharged from each of the heads 101 and 102 is not uniform and the surface is not flat, but the thickness of each layer is made uniform by the rotating smooth roller 103, and Smoothly control surface flatness.

  The light source 104 collectively irradiates the modeling material 12 discharged onto the modeling stage 11 with light to cure the modeling material 12. When the 3D printer in FIG. 1 completes the light irradiation, the modeling stage 11 is moved by one layer downward in the Z-axis direction, and the above steps are repeated until the uppermost layer is formed.

Next, with reference to the circuit block of FIG. 2, the control system of the three-dimensional molded item formation apparatus used for the manufacturing method of the honeycomb structure by this invention is demonstrated.
The X-axis direction control unit 21 and the Y-axis direction control unit 22 drive and control the head 10 in the X-axis direction and the Y-axis direction, respectively, according to a control signal from a CPU (control unit) 29, and the Z-axis direction control unit 23 The modeling stage 11 is driven and controlled in the Z-axis direction at a stacking pitch of one layer.

  The modeling material supply head control unit 24 refers to the slice data to control the supply of the modeling material 12 from the modeling material supply head 101, and the support material supply head control unit 25 also refers to the slice data to supply the support material. The supply of the support material 13 from the head 102 is controlled.

  Further, the light source control unit 26 controls irradiation of the light source 104. That is, referring to the slice data, the modeling material 12 and the support material 13 are laminated one layer further, and then controlled so as to irradiate light non-selectively from the light source 104 so as to include these lamination regions. 12 is cured.

  In the above description, the modeling material 12 laminated in a predetermined pattern with reference to the slice data is cured by non-selectively irradiating light from the light source 104. 11 is stacked substantially non-selectively on one layer, and refers to slice data, and scans light beams such as laser light from the light source 104 so as to form predetermined patterns in the X-axis direction and the Y-axis direction. You may do it.

  Further, the modeling material 12 is substantially non-selectively laminated on the modeling stage 11, and slice data is referred to generate a region where light is transmitted and a region where light is not transmitted by a liquid crystal shutter or the like, and is transmitted through the liquid crystal shutter or the like. You may comprise so that light may be made into the shape corresponding to slice data and the modeling material 12 may be exposed collectively.

  2 is a 3D image visualized based on an STL (Standard Triangulated Language) file of a three-dimensional object to be manufactured by a 3D printer, and up to 3 layers of stacked layers. A three-dimensional image, a slice data image, a modeling temperature, a stacking pitch, an expected time and an estimated time until completion of modeling, an expected amount of the modeling material 12 to be consumed, various alarm information, and the like are displayed.

  The operation unit 28 receives the operation from the user and outputs the instruction information to the CPU 29. A bus 210 indicates a data bus, a memory bus, and the like, and transmits data between the CPU 29, the control units 21 to 26, the monitor unit 27, and the operation unit 28.

  Note that a number of sensors such as a temperature sensor and a position sensor are usually mounted on the 3D printer, but these sensors are not shown in FIGS. 1 and 2.

  FIG. 3 is a flowchart for explaining the honeycomb structure manufacturing method according to the first embodiment of the present invention. In step S1 of FIG. 3, the user inputs 3D data in the STL format created by a 3D CAD tool, 3D scanner, or the like from a server or a USB memory to the 3D printer.

  The three-dimensional CAD tool used at this time is flexible by using a feature-based three-dimensional CAD tool that changes a parameter by changing a parameter of a single shape attribute (feature) that is history-managed, And a desired honeycomb structure can be manufactured rapidly.

  Next, in step S2, the CPU 29 performs an error check on the input three-dimensional data. If there is a problem as a result of the error check, the three-dimensional data is corrected. If there is no problem, the slicer software is used to convert the three-dimensional data into a layered model (slice data) for each layer. G code for controlling the 3D printer is generated.

  Furthermore, in the next step S3, the CPU 29 refers to the G code, and controls the head 10 through the respective control units 21 to 25 to discharge the modeling material 12 from the modeling material supply head 101 to the modeling area. In addition, the support material 13 is discharged from the support material supply head 102 to the support area, and a layer of the modeling area and the support area are stacked at the same time.

  As will be described later, the cell bottom wall forming the honeycomb structure of the present invention has a concave first inclination angle in the depth direction and is extremely thin. In order to realize such a cell bottom wall, it is extremely important to appropriately design the support material 13 in order to stably manufacture the honeycomb structure of the present invention.

  Subsequently, the CPU 29 cures the modeling material 12 stacked in one layer of the modeling region by non-selectively irradiating light such as ultraviolet rays from the light source 104 to the irradiation target region via the light source control unit 26. (Step S3). This process is repeated one layer at a time until reaching the highest layer (step S3).

  When step S3 is completed, the honeycomb structure formed in step S3 is separated from the modeling stage 11 in step S4. As an example, by cooling or heating the metal modeling stage 11 and the honeycomb structure, the honeycomb structure is separated from the modeling stage 11 using the difference in thermal expansion coefficient between the modeling stage 11 and the honeycomb structure. Other separation methods may be used. In step S5, the user puts the separated honeycomb structure in an oven or the like and heats it to 60 ° or more to melt and remove the support material 13.

  Subsequently, in the first cleaning step S6, the honeycomb structure was immersed in a solution such as oil heated to a high temperature and ultrasonically cleaned using an ultrasonic cleaner, and then used in step S6 in the second cleaning step S7. The oil and the residue of the support material 13 are removed using a detergent. Here, the inventors of the present invention have found a problem related to cleaning unique to the honeycomb structure in step S6.

  FIG. 4 is a diagram for explaining a problem related to cleaning unique to the honeycomb structure in step S6 of FIG. FIG. 4A shows that when the honeycomb structure 41 is ultrasonically cleaned, the support material 13 formed in contact with the cell bottom wall 42 is stirred by convection or the like and adheres to the cell side wall 43 as a residue 44. It shows a state.

  When the cell size is small and the cell internal space is deeper than the cell size, as shown in FIG. 4A, it is easy to completely remove the residue 44 attached to the cell side wall 43 in step S6 in the next step S7. Not. Eventually, if the residue of the support material 13 is not completely removed from the honeycomb structure, the honeycomb structure comes to have a strange odor and stickiness peculiar to the support material 13. Such a honeycomb structure cannot be a desirable artificial nest spleen for bees.

  FIG. 3B is a flowchart obtained by improving the first cleaning step S6 of FIG. 3A, and FIG. 4B is a diagram for explaining means for solving the problem described above. In step S6 of FIG. 3B, first, in step S61, the entire cell opening is covered with a cell sealing material (cell sealing means) 45 such as a sheet, and in this state, in step S62. A first cleaning is performed.

  By such a procedure of steps S61 and S62, the residue of the support material 13 is not mixed and attached to the cell internal space, so that a clean honeycomb structure 41 from which the support material 13 is removed can be formed. It becomes possible to produce an artificial nest spleen that is preferable for the bees without the unusual smell and stickiness peculiar to the support material 13.

  Although the honeycomb structure 41 has been described above, this method is not limited to the honeycomb structure 41 and is also applicable to the case where the support material 13 is not formed in the internal space and the gap between the internal space and the surface is narrow. The technical idea of cleaning after sealing the entrance of the cell internal space using the cell sealing material 45 can be widely applied.

  When manufacturing the honeycomb structure 41 according to the present invention, since the support material 13 is formed only on the outer surface of the cell bottom wall 42, step S5 is not performed without performing the first cleaning (ultrasonic cleaning) in step S6. After the process, the second cleaning in step S7 may be performed.

Returning to FIG. 3, the description will be continued.
In step S8, the honeycomb structure 41 manufactured as described above in steps S1 to S7 is mounted on a nest box as an artificial nest spleen for beekeeping, and field evaluation is actually performed. That is, the bees and the bee colonies are observed, and how the bees use the artificial nest spleen according to the present invention, and the behavior and the production efficiency of honey are evaluated.

  At this time, the behavior of bees varies greatly depending on the environment, including the natural environment, so prototype artificial nest spleens were prototyped under multiple conditions, and these artificial nest spleens were mounted in a nest box to change the installation location in various ways. Observe in detail. At this time, the bee's behavior is to install observation equipment such as a super slow motion monitoring camera, an infrared camera for observing nighttime activities, a highly sensitive microphone for observing sound and vibration, and a vibration meter in the nest box. May be observed.

  Next, in step S9, evaluation is performed based on the observation data obtained in step S8, and it is determined whether or not the evaluation result satisfies the specification. If the evaluation result satisfies the specification (OK in step S9), a series of operations are completed in step S11 assuming that the production target of the artificial nest spleen has been achieved. On the other hand, when the evaluation result does not achieve the specification (NG in step S9), the process proceeds to step S10 to analyze the evaluation result and correct the design parameter.

  Bees are said to spend more than 90% of their lives in the nest spleen even in the case of worker bees, and nest spleen is an important living infrastructure for bees (abbreviation for infrastructure [UK]). Therefore, providing a suitable artificial nest spleen to bees is extremely important for beekeeping. Examples of the analysis in step S10 include the following items.

(1) Establishing rate to artificial nest spleen as a whole colony (2) Spawning rate of queen bee (3) Growth rate from larvae to adults As an example, nest spleen with nest foundations formed on both sides across the cell bottom wall In this case, there is a dimension suitable for the thickness of the cell bottom wall constituting the nest spleen. If the thickness is larger than this dimension, communication between the larvae via the cell bottom wall is insufficient, and the growth of the larvae is slowed. In addition, when observing two cells that are symmetrically related to the cell bottom wall, the bees act to accumulate nectar on the other when nectar is accumulated on one side, and to collect pollen on the other side when pollen is accumulated on the other side. To do. These can only be considered that when the cell bottom wall is thin, the bees exchange information with each other through the cell bottom wall. Therefore, the growth rate from the larva to the adult is observed by changing the conditions of the cell bottom wall that constitutes the artificial nest spleen that was prototyped in the present invention, and the storage that is stored in two cells symmetrical to the cell bottom wall is observed.
(4) Degree of bee reconstitution with respect to artificial nest spleen Ratio of bees themselves to be constructed with respect to artificial nest spleen according to the present invention, degree of energy required for reconstitution (5) Production amount of honey in unit nest spleen, and honey Quality (6) Degree of protection against infection by pathogenic bacteria

  The items (1) to (6) are analyzed, and the structural parameters of the honeycomb structure 41, the material of the modeling material 12, and the additive material mixed in the modeling material 12 are determined with reference to the honeycomb structure file 31. . The honeycomb structure file 31 stores a feature-based model, and the shape of the honeycomb structure 41 can be flexibly changed by changing the structure parameter.

  Since the correlation between the analysis result analyzed in step S10, the structural parameter, the material of the modeling material 12, the material of the additive material, and the additive amount is stored in the honeycomb structure file 31 and updated together with the update history information, Each time field evaluation is repeated, the quality of the honeycomb structure as an artificial nest spleen is improved.

  After the structural parameters of the honeycomb structure 41, the material of the modeling material 12, and the additive material mixed in the modeling material 12 are determined in step S10 to generate three-dimensional data, the three-dimensional data is read again into the 3D printer in step S1. . In this manner, a honeycomb structure as an artificial nest spleen suitable for bees and colonies can be developed and manufactured while repeating trial manufacture using a 3D printer and various observations by field evaluation.

  Since the conventional honeycomb structure is manufactured using a mold, it has been difficult to flexibly and rapidly manufacture a honeycomb structure suitable as an artificial nest spleen. Since the three-dimensional CAD tool and the analysis result are stored and the honeycomb structure file 31 that is continuously updated is integrated and closely integrated, the honeycomb structure 41 suitable as an artificial nest spleen is flexible and flexible. It can be manufactured quickly.

  FIG. 5 is a perspective view showing the appearance of the honeycomb structure according to Embodiment 1 of the present invention. 6 is a view showing a cross section of the honeycomb structure according to Embodiment 1 of the present invention, and FIGS. 6 (a) and 6 (b) are cross sectional views taken along the lines PP and QQ in FIG. 5, respectively. It is.

  5 and 6, reference numeral 51 denotes a cell bottom wall. As shown in FIG. 5, six cell side walls 52 are erected on six sides of the hexagonal cell bottom wall 51, and cells 53 are formed from the cell bottom wall 51 and the six cell side walls 52. ing. In FIG. 6A, of the cell side walls 52 and 52 ′ with respect to the cell bottom wall 51, the cell side wall 52 extends in the direction of the paper surface depth (X axis positive), and the cell side wall 52 ′ is left and right of the paper surface. It extends in the direction (both positive and negative on the Y axis). A plurality of such cells 53 are arranged in an array to form a flat honeycomb structure shown in FIG.

  6 (a) and 6 (b), when viewed from the opening side of the cell 53, the cell bottom wall 51 has six isosceles triangles that are thinly formed as 0.25 mm and the cell center is the center of the cell. A hexagonal pyramid shape (conical shape) is formed at a first inclination angle from the horizontal plane (XY plane) toward the portion. This shape was determined with reference to the structure of the natural nest spleen.

  In FIG. 6A, reference numeral 61 denotes a support material. As can be easily seen from FIG. 6A, the support material 61 forms a hexagonal pyramid-shaped cell bottom wall 51 protruding rearward of the cell 53 (in the negative direction of the Z axis) in the ink jet method. Indispensable. That is, the height of the cell bottom wall 51 in the stacking direction (Z-axis direction) increases from the position A to the position B in FIG. For this reason, when the cell bottom wall 51 is formed only by the modeling material 12 without using the support material 61, the cell bottom wall 51 is coupled with the thin cell bottom wall 51, so that an overhang occurs and the flat cell bottom wall 51 is formed. I can't.

  Therefore, in the honeycomb structure manufacturing method according to the present invention, the support material 61 is stacked on the modeling stage 11 along the hexagonal pyramid shape of the cell bottom wall 51, and the modeling material is formed on the support material 61 stacked in the concave shape of the hexagonal pyramid. By stacking 12 layers one by one, a cell bottom wall 51 protruding rearward in a hexagonal pyramid shape is formed. Needless to say, the support material 61 is laminated on the entire hexagonal pyramid, and then the modeling material 12 is not laminated on the upper surface. The modeling material 12 is laminated | stacked on the upper surface of the lower layer of this support material 61, and the upper surface of the modeling material 12 modeled below one layer, respectively. On the other hand, in the slanting surface that is on the lower left, the modeling material 12 is laminated on the upper surface of the lower layer of the support material 61 and the upper surface of the modeling material 12 that is modeled below the support material 61 from the left end of the support material 61 in one lamination surface. The Therefore, even if the cell bottom wall 51 is very thin, the cell bottom wall 51 can be laminated stably.

  Another point, as can be seen from FIG. 6 (b), in each cell 53, the cell side walls 52, 52 ′ are formed so as to incline at a second inclination angle with respect to the Z-axis direction. All cells in the body are inclined to the same side. When such a honeycomb structure 41 is used as an artificial nest spleen, the right side of the paper in FIG. 6B is the upper side during mounting, and the left side of the paper is the lower side during mounting, so that the cell opening is more than the cell bottom wall 51. If it is mounted on the nest box so that it is at a high position, the cell central axis 54 (that is, the entire cell 53) faces diagonally upward, so that the honey stored in the cell 53 is less likely to overflow from the opening and prevents honey from flowing out. can do.

  In the cell 53, the distance between the cell side walls 52, 52 facing each other and the distance between the cell side walls 52 ′, 52 ′ facing each other is 5.8 mm, and the thickness and height of each of the cell side walls 52, 52 ′ is 0.25 mm. And 8 mm. These dimensions are examples as described in the flowchart of FIG. 3, and are designed to meet various artificial nest spleen specifications required by beekeepers because they differ depending on the type of bees and the environment in which the nest box is installed.

  In addition, as the modeling material 12 for forming the cell bottom wall 51 and the cell side walls 52 and 52 ′, an acrylic resin having a color similar to that of a natural nest spleen is used, but other materials such as an ABS (Acrylonitrile Butaylene Styrene) resin, Polycarbonate may be used.

  Furthermore, a polylactic acid resin may be used as the modeling material 12. In this case, since it can be easily decomposed by underground microorganisms or the like, there is an advantage that the honeycomb structure 41 with reduced environmental load can be manufactured.

  In the above description, the modeling direction has been described as the direction from the cell bottom wall 51 to the opening of the cell 53 as shown in FIGS. 6A and 6B. There may be. For example, you may model in the cell bottom wall 51 direction from an opening part reversely to the above-mentioned direction. However, since the support material 61 is filled in the cell 53 in this case, it is difficult to completely remove the support material 61 filled in the cleaning steps S6 and S7. In addition, an extra amount of support material is consumed. As can be seen from the above description, the stacking direction described in FIGS. 6A and 6B is a preferable stacking direction.

  As described above, according to the first embodiment, a cell including the cell bottom wall 51 having a hexagonal shape and the six cell side walls 52 and 52 ′ standing on each side of the cell bottom wall 51. In the honeycomb structure manufacturing method for manufacturing the honeycomb structure 41 having a plurality of 53, first steps S1, S2 for inputting the three-dimensional data of the honeycomb structure 41 and converting the three-dimensional data into slice data And by referring to the slice data converted in the first steps S1 and S2, by laminating the modeling material 12 and the support material 13 of a material different from the modeling material 12 on the modeling stage 11, the cell bottom wall 51 is A second step S3, which is formed in a hexagonal pyramid shape protruding rearward and the cell side walls 52, 52 ′ are erected so that all the cells 53 are inclined to the same side, Since the honeycomb structure 41 formed in step S3 of 2 is separated from the modeling stage and the third steps S4 and S5 for removing the support material 13 are provided, the honeycomb structure 41 rich in variations is 3D. The printer can be manufactured quickly, and there is no need for a mold or other special manufacturing apparatus, and the manufacturing cost can be reduced. In addition, by stacking the modeling material 12 on the support material 13 made of a material different from the modeling material 12, the hexagonal pyramidal cell bottom wall 51 protruding rearward can be formed thinly. When mounted in a nest box as an artificial nest spleen, an effect that a suitable environment for bees can be provided is obtained.

  Further, according to the first embodiment, a base having an inclined surface is formed on the modeling stage 11 by the support material 61, and the cell bottom wall 51 is formed on the inclined surface substantially perpendicularly to the inclined surface. Since the modeling material 12 is laminated and formed, the effect that the cell bottom wall 51 can be stably laminated even if the cell bottom wall 51 is extremely thin can be obtained.

  Further, according to the first embodiment, in the second step S3, the cell side walls 52 and 52 ′ are formed so as to be inclined so that all the cells 53 are inclined to the same side. By mounting in the nest box such that the cell opening is positioned higher than the cell bottom wall 51, an effect of preventing the honey accumulated in each cell 53 from flowing out can be obtained.

  Further, according to the first embodiment, after the third steps S4 and S5, step S61 covering the entire cell opening of the honeycomb structure 41 from which the support material 13 has been removed with the cell sealing material 45, and this Since the fourth step S6 including the step S62 for cleaning the honeycomb structure 41 in the state is provided, the residue of the support material 13 that has not been completely removed in the third steps S4 and S5 enters the cell internal space. Intrusion can be prevented, a clean honeycomb structure 41 can be formed, and a honeycomb structure suitable as an artificial nest spleen that does not have the odor and stickiness peculiar to the support material 13 can be manufactured. The effect is obtained.

  Furthermore, according to the first embodiment, since the polylactic acid resin is used as the modeling material 12 in the second step S3, the honeycomb structure 41 that can be easily decomposed by underground microorganisms or the like is formed. The effect that the honeycomb structure 41 with reduced environmental load can be manufactured is obtained.

  Furthermore, according to the first embodiment, after the third steps S4 and S5, the honeycomb structure 41 is mounted on the nest box as an artificial nest spleen, field evaluation is performed, and observation data regarding the honeycomb structure 41 is acquired. The honeycomb structure 41 is evaluated based on the fifth step S8 and the observation data acquired in the fifth step S8, and it is determined whether or not the evaluation result satisfies the specification of the honeycomb structure 41. When the evaluation result does not satisfy the specifications in the sixth step S9 and the sixth step S9, the evaluation result analysis and the design parameter correction are performed on the honeycomb structure 41, and the result is stored in the honeycomb structure file 31. 7th step S10 utilized for manufacture of the honeycomb structure 41 in following step S1-S5 while storing. The conventional honeycomb structure manufacturing method in which the quality of the honeycomb structure 41 can be improved every time manufacturing and field evaluation are repeated, and it is difficult to flexibly and quickly develop a suitable nest spleen because of the use of a mold. In comparison, an advantageous effect that a suitable honeycomb structure 41 can be manufactured flexibly and rapidly is obtained.

Embodiment 2. FIG.
In steps S1 and S2, the following structure shown in FIG. 7 may be input by being included in the three-dimensional data and converted into slice data.

  FIG. 7 is a front view showing the appearance of a honeycomb structure according to Embodiment 2 of the present invention. A part or all of the outer periphery of the honeycomb structure 71 as a worker beehive artificial nest spleen is used as a worker bees artificial nest spleen. A sub-honeycomb structure 72 as a beehive spleen having a plurality of male bee cells larger than the worker bee cell of the honeycomb structure 71 is arranged.

  In this second embodiment, since the sub-honeycomb structure 72 necessary for the breeding period is provided integrally with the honeycomb structure 71, there is no need for the worker bees to make a male honeycomb spleen using precious colony resources, Production efficiency is further improved.

  Since the sub-honeycomb structure 72 is necessary only as a beehive spleen only during the bee breeding period, the sub-honeycomb structure 72 may be usually covered and the cover removed only during the breeding period.

  Further, a part or the whole of the sub-honeycomb structure 72 may be an attachment method, and the sub-honeycomb structure 72 having a required number of cells may be connected to the honeycomb structure 71 at a necessary time to constitute an artificial nest spleen. good.

  Further, in FIG. 7, reference numeral 73 denotes a cap-like structure used as an artificial royal ring, 731 denotes a part of the cap-like structure 73, and the cap-like structure 73 is joined to the honeycomb structure 71 or the sub-honeycomb structure 72. The cap-like structure side coupling portion 74 for separation is provided in the honeycomb structure 71 or the sub-honeycomb structure 72, and the cap-like structure side coupling portion 731 is coupled to and separated from the honeycomb structure 71 or the sub-honeycomb structure 72. It is a honeycomb structure side joint part for doing.

  As shown in FIG. 7, the cap-like structure 73 is combined with the honeycomb structure 71 or the sub-honeycomb structure 72 via the cap-like structure-side coupling portion 731 and the honeycomb structure-side coupling portion 74, and is necessary as an artificial prince. Use as many as possible. When the queen bee is not produced, the opening of the cap-like structure 73 may be sealed with a cap or the like.

  The cap-like structure 73 according to the second embodiment can constitute an artificial nest spleen in which the honeycomb structure 71 or the sub-honeycomb structure 72 and the cap-like structure 73 are integrated when it is necessary to produce a queen bee. This eliminates the need for worker bees to make natural kingdoms using valuable colony resources, further improving honey production efficiency.

  Since the sizes of the working bee cell of the honeycomb structure 71, the bee cell of the sub-honeycomb structure 72, and the cap-like structure 73 are different from each other, in the honeycomb structure manufacturing method by the normal stretching method, each of these cells and caps is used. In other words, it is difficult to manufacture a hybrid honeycomb structure in which the structure 73 is mixed. In contrast, the honeycomb structure manufacturing method according to the present invention refers to slice data converted from three-dimensional data, cures the modeling material 12 laminated by a 3D printer, and forms the honeycomb structure 71, the sub-honeycomb structure 72, and the cap. Since the structure 73 is manufactured, even a complicated hybrid honeycomb structure can be easily manufactured.

  Note that various methods such as a screw method, a method of inserting a pin-like member into the opening, and a fixing method using an adhesive or the like can be applied as a method of bonding the cap-shaped structure side bonding portion 731 and the honeycomb structure side bonding portion 74. .

  In particular, when a screw method using a male screw and a female screw is adopted as a method of joining the cap-like structure side joint portion 731 and the honeycomb structure side joint portion 74, the support material 13 is placed between the male screw and the female screw. By arranging and finally removing the support material 13, all components can be manufactured in one manufacturing flow, so that not only the accuracy as a screw is high, but also the manufacturing efficiency is high. is there. The same applies to a method of inserting a pin-like object into the opening.

  As described above, according to the second embodiment, in the first steps S1 and S2, a plurality of bee cells larger than the working bee cells of the honeycomb structure 71 are provided, and at least the outer peripheral portion of the honeycomb structure 71 is provided. Since the sub-honeycomb structure 72 arranged in a part is included in the three-dimensional data and converted into slice data, the honeycomb structure 71 is used as a worker beehive spleen, which is necessary only for the breeding season. As the nest spleen can be used to construct an artificial nest spleen that integrates the sub-honeycomb structures 72, it is no longer necessary to make a bee spleen by using a valuable colony resource. Can be further improved.

  According to the second embodiment, in the first steps S1 and S2, the cap-like structure 73 that can be combined with and separated from the honeycomb structure 71 or the sub-honeycomb structure 72 is included in the three-dimensional data and input. Since the data is converted into slice data, the honeycomb structure 71 is used as the worker beehive spleen, the sub-honeycomb structure 72 is used as the male beehive spleen, and the cap-like structure 73 is used as the artificial prince. Since an artificial nest spleen that integrates these can be constructed, there is no need for worker bees to make artificial kings using precious colony resources, and the effect of further improving honey production efficiency can be obtained.

Embodiment 3 FIG.
In the honeycomb structure manufacturing method according to the first and second embodiments, the case where a resin is used as the modeling material 12 has been described. Recently, a three-dimensional modeling method for laminating paper called Paper 3D Printing has been developed, and modeling of a three-dimensional map, etc. Has been applied. In this three-dimensional modeling method, printing and coloring on paper with an inkjet printer, etc., cutting the paper into a shape corresponding to the slice data for each layer, and shaping and cutting the cut paper from the bottom layer in order by repeating lamination and adhesion To do.

  When this three-dimensional modeling method of laminating paper is used in the honeycomb structure according to the present invention, the weight of the honeycomb structure can be reduced as compared with the case of modeling with a resin.

  Also, by stacking colored paper, it is easy to make the nest foundation the color that bees like.

  Furthermore, a honeycomb structure can be manufactured as an artificial nest spleen similar to a natural nest spleen by forming a nectar film by spraying beeswax or honey on the honeycomb structure manufactured by paper.

  Further, the honeycomb structure made of paper is dipped in beeswax to coat the cell bottom wall 51 or the cell side walls 52, 52 ′ with a beeseal film, and then placed in a centrifuge to control the rotation speed, thereby controlling the coated honeycomb. The thickness of the film may be controlled.

  Furthermore, when beeswax is used as the modeling material 12 instead of resin, a honeycomb structure can be manufactured as an artificial nest spleen that is very close to the natural nest spleen.

  As described above, according to the third embodiment, in the second step S3, instead of the modeling material 12 and the support material 13, paper cut into a shape corresponding to the slice data is stacked. As compared with the case of manufacturing with a resin or the like, the honeycomb structure can be reduced in weight.

  Further, according to the third embodiment, since the colored paper is laminated in the second step S3, an effect that a honeycomb structure colored in the color preferred by the bees can be manufactured is obtained.

  Further, according to the third embodiment, after the third steps S4 and S5, the eighth step of forming a nectar film by spraying beeswax or honey on the cell bottom wall 51 or the cell side walls 52, 52 ′ is performed. Since it was provided, the effect that a honeycomb structure can be manufactured as an artificial nest spleen close to a natural nest spleen is obtained.

  Further, according to the third embodiment, after the third steps S4 and S5, the honeycomb structure is dipped in beeswax or honey to coat the cell bottom wall 51 or the cell side walls 52, 52 ′ with a beeswax film, Since the ninth step of controlling the thickness of the honeycomb membrane immersed in beeswax or honey by centrifugation is provided, the honeycomb structure can be manufactured as an artificial nest spleen close to a natural nest spleen. can get.

  Furthermore, according to the third embodiment, since the beeswax or honey is laminated as the modeling material 12 in the second step S3, the honeycomb structure can be manufactured as an artificial nest spleen very close to the natural nest spleen. An effect is obtained.

Embodiment 4 FIG.
In steps S1 and S2 in FIG. 3, a structure as shown in FIG. 8 may be input as included in the three-dimensional data and converted into slice data.

FIG. 8 is a view for explaining the shape of a cell provided in a honeycomb structure according to Embodiment 4 of the present invention.
Generally, the edge of the upper end of the cell is swollen, and it is known that the bees roam around this edge and also vibrate to communicate with their friends (refer to Chapter 7 of Non-Patent Document 1). In the fourth embodiment, as shown in FIG. 8, the cell upper end 52u of the cell side wall 52 is larger than the thickness of the cell side wall 52 (the inner diameter of the portion other than the cell upper end 52u of the cell side wall 52). Configure as follows.

  FIGS. 8A, 8B, 8C, and 8D illustrate cases where the shape of the cell upper end 52u is a rectangle, a triangular pyramid, a sphere, and an ellipse, respectively. However, the shape of the cell upper end 52u is not limited thereto, and may be any shape that swells outside the cell side wall 52.

  By adopting this structure for the cell upper end 52u of the honeycomb structure according to the present invention, it becomes easy for the bees to walk around the edge, and it is possible to efficiently perform signal transmission when performing communication by causing vibration. Nest spleen can be provided.

  Moreover, it is possible to prevent the honey accumulated in the cell inner space from leaking out by the edge.

  As described above, according to the fourth embodiment, in the first steps S1 and S2, the cell upper end 52u having a shape larger than the thickness of the cell side wall 52 is included in the three-dimensional data, and is converted into slice data. This makes it easier for the bees to walk around the edge of the cell upper end 52u, and allows the bees to vibrate and communicate efficiently with their peers. The effect is that an artificial nest spleen in which honey does not leak out by the edge can be provided.

Embodiment 5. FIG.
In step S1 of FIG. 3 (a), 3 is information unique to the manufacturing of the honeycomb structure, such as the manufacturing number of the honeycomb structure, the date of manufacture, and the like, which is formed and displayed on the honeycomb structure. Dimensional data may be input and converted to slice data.

  In this way, the honeycomb structure and the unique information can be integrally formed and displayed, and a method of stamping the unique information on the honeycomb structure with a laser beam or the like, or a seal printed with the unique information is provided. The unique information can be reliably and efficiently displayed on the honeycomb structure as compared with a method of displaying in a subsequent process such as a method of attaching to the honeycomb structure.

  Moreover, in FIG. 7, you may comprise so that the number corresponding to each of the cap-shaped structure side coupling | bond part 731 and the honeycomb structure side coupling | bond part 74 may be modeled, and the efficiency at the time of combining these may be improved.

FIG. 9 is a plan view for explaining the method for manufacturing a honeycomb structure according to the fifth embodiment of the present invention.
For example, in FIG. 9A, in a plan view of the honeycomb structure, a predetermined thickness is formed along a horizontal arrow arw from the upper left end to the upper right end parallel to the cell side walls 52h, 52l,. The cell side wall 52h having a certain thickness (unique information) and the cell side wall 52l having a predetermined thickness (unique information) are respectively coded as “1” “0” “1” “1” “0” “0” “1” “0”. It has become.

  In FIG. 9A, after coding up to the upper right corner of the honeycomb structure, other cell rows, for example, the cell side walls 52h, 52l,. .

  Further, for example, in FIG. 9B, in a plan view of the honeycomb structure, a predetermined thickness (proprietary information) is observed along an oblique arrow arw extending from the upper right end to the lower left end perpendicular to the cell side walls 52h and 52l. ) And the side wall 52l of a predetermined thickness (unique information) are coded as “1” “0” “0” “1” “1” “1” “0” “1”, respectively. When coding in an oblique direction, the number of cell side walls 52h and 52l to be coded increases, so it is preferable when the amount of information to be coded is large.

  In FIG. 9B, after coding up to the corner portion at the lower left corner of the honeycomb structure, other diagonal cell rows may be coded continuously. The encoding direction at this time does not have to be parallel to the arrow arw shown in FIG. 9B, and may be a direction that forms an angle of 60 ° or 120 ° with the direction of the arrow arw.

  By doing in this way, the effect of being able to provide the coding method universally with respect to the honeycomb structure modeled by 3D printer, and reducing data amount is acquired.

  In the above description, as the unique information, the thickness / thinness of the cell side wall 52h is coded as “1” / “0”, respectively. The thick 52u may be “1” (or “0”), and the thin 52u may be “0” (or “1”).
