  As described above, various methods for manufacturing a desired composite member by applying a coating layer formed of a material different from the core material on the outer surface of the member to be the core material have been devised, and manufacturing apparatuses corresponding thereto Has also been devised. It is an object of the present invention to provide a novel manufacturing apparatus that is completely different from the manufacturing apparatuses as described above, in particular, a novel manufacturing apparatus for a composite member that is manufactured by fixing a surface member to the outer peripheral surface of a core material. To do.

The object of the present invention is a manufacturing apparatus for manufacturing a composite member in which a surface member is fixed to the outer peripheral surface of a core material, and a surface member disposing means capable of disposing the surface member on the outer peripheral surface of the core material; , the core is heated by the heat of the heated said core, at least one allowed one to melt the region opposed to the said surface member disposed on the outer peripheral surface of the core material and the core material, wherein Heating means for fusing the surface member and the core material without damaging the outer surface shape of the surface member arranged on the outer peripheral surface of the core material by heat melting, the surface member arrangement means, This is achieved by a composite member manufacturing apparatus that is a covering device that covers the outer peripheral surface of the core member with the surface member by winding a surface member made of a wire around the outer peripheral surface of the core member . Alternatively, a manufacturing apparatus for manufacturing a composite member having a surface member fixed to an outer peripheral surface of a core material, the surface member disposing means capable of disposing the surface member on the outer peripheral surface of the core material, and the core material The outer peripheral surface of the core material is heated and melts at least one of the facing regions of the surface member and the core material disposed on the outer peripheral surface of the core material by the heat of the heated core material. Heating means for fusing the surface member and the core material without damaging the outer surface shape of the surface member disposed on the surface by heat melting, and the surface member disposing means is granular or fibrous By spraying the surface member onto the outer peripheral surface of the core member, this is achieved by a composite member manufacturing apparatus that is a spraying device that covers the outer peripheral surface of the core member with the surface member.

  According to such a composite member manufacturing apparatus, the portion to be thermally melted is at least one of the opposed regions of the surface member and the core material (the opposed region of the surface member to the core material, or the surface member of the core material) Therefore, the surface member is surely placed on the outer peripheral surface of the core material without damaging the shape of the outer surface of the surface member disposed on the surface of the core material by heat melting. It becomes possible to fuse and fix. Further, in the stage of arranging the surface member on the outer peripheral surface of the core material, even when a material that is difficult to be generated in a liquid state is selected as the surface member, the surface member is in the form of a wire or particles. By forming the surface member, it is possible to fuse such a surface member onto the outer peripheral surface of the core material.

  In this composite member manufacturing apparatus, the core member is formed of a conductive material, the surface member is formed of a material having lower magnetism than the core member, and the heating means includes the core member. It is preferable that it is an electromagnetic induction heating apparatus which heats the said core material by the electromagnetic induction heating system from the outer side of the said surface member arrange | positioned by the outer peripheral surface of this.

  By adopting such a configuration, from the outside of the surface member disposed on the outer peripheral surface of the core material (from the outside of the composite member), it is possible to easily heat the core material arranged inside, The productivity of the composite member can be improved.

  In the composite member manufacturing apparatus, the surface member disposing unit may be configured to dispose the surface member on an outer peripheral surface of the core member heated by the heating unit. Even in such a configuration, at least one of the facing regions of the surface member and the core material disposed on the surface of the core material is thermally dissolved by the heat of the heated core material, so that the surface member is cored. Can be fixed to the material.

  Further, an adhesive layer forming means for applying an adhesive having a melting point lower than the melting point of the core material to the outer peripheral surface of the core material in advance with respect to the core material on which the surface member is disposed on the outer peripheral surface. It is preferable to provide.

  When such an adhesive layer forming means is provided, by heating the core material, for example, a member having a melting point lower than the melting point of the core material is used as the surface member, and the adhesive used in the adhesive layer forming means is used. When the adhesive has a melting point of the adhesive substantially equal to or lower than the melting point of the surface member, by heating the core member, the region facing the core member in the surface member and between the surface member and the core member It is possible to dissolve the adhesive intervening, and to fix the surface member to the core material more firmly. Specifically, as the surface member, a wire rod that is spirally wound around the outer peripheral surface of the core material or a granular or fibrous member that is disposed on the outer peripheral surface of the core material by spraying is used. In this case, the melted adhesive enters the gap between the adjacent wire and granular members, so that the surface member can be securely fixed to the core.

  Moreover, it is preferable that an adhesive bond layer formation means is further equipped with the drying apparatus which dries the adhesive agent apply | coated to the outer peripheral surface of the said core material.

  In this way, by configuring the adhesive applied to the outer peripheral surface of the core material to dry, the surface member can be disposed on the outer peripheral surface of the core material in a state where the adhesive strength of the adhesive is lost. It becomes. The surface member may be disposed on the outer peripheral surface of the core material even in a situation where the adhesive has an adhesive force, that is, the adhesive is not dried, but the adhesive is not dried and the adhesive is bonded. When the surface member is disposed on the outer peripheral surface of the core material in a liquid or semi-liquid state, the liquid (or semi-liquid) adhesive oozes from around the disposed surface member. The adhesive may remain on the outer surface of the finally obtained composite member. Alternatively, the liquid (or semi-liquid) adhesive may flow along the outer peripheral surface of the core material, and the adhesive may not be uniformly distributed on the outer peripheral surface of the core material. In such a case, for example, when the core material Z1 is heated to melt the adhesive and / or the surface member of the surface member facing the core material, and the surface member is fixed to the core material, the adhesive is thin. There is a possibility that the fixing force between the surface member and the core material in the portion applied to the material surface may be reduced. On the other hand, in the previous stage of disposing the surface member on the outer peripheral surface of the core material, after drying the adhesive applied to the outer peripheral surface of the core material, when disposing the surface member on the outer peripheral surface of the core material, It is possible to effectively prevent the situation described above (adhesive leaching and non-uniform distribution of the adhesive) from occurring, and the adhesive remains on the outer surface of the finally obtained composite member. It is possible to reliably prevent the occurrence of a portion where the adhesion between the surface member and the core member is reduced.

The core material Z1 is preferably composed of a material that easily conducts electricity (conductive material). The shape of the core material Z1 is not particularly limited, and various shapes such as a rod shape, a wire shape, a columnar shape, and a hollow cylindrical shape can be adopted. Further, the core material Z1 may be composed of a single material according to its function, or may be composed of a plurality of materials. As the core material Z1 composed of a plurality of materials, for example, one obtained by twisting two types of wire-like metal members, one obtained by twisting wire-like metal members and wire-like resin members, Various materials such as those formed from a material different from the surface part (two-layer structure, for example, a member in which the outer surface of the central part made of metal is coated with a thermosetting resin to form the surface part) The configuration can be adopted. When the core material Z1 is composed of a plurality of materials, at least one kind of material is made easy to conduct electricity, and the core material Z1 as a whole is configured to have conductivity.

  Various members can be adopted as the surface member Z2, for example, it may be formed from a metal material such as iron or stainless steel, or may be formed from a synthetic resin material. Preferred examples of the synthetic resin material include a fluorine resin, a polyester resin, a polyamide resin, and a polyolefin resin. In addition, when the composite member Z is provided with one function selected from various functions such as a corrosion resistance function, a lubricity function, a heat insulation function, and a fatigue resistance function, a material suitable for providing a desired function. May be selected as the surface member Z2. Or when giving a some function simultaneously, what is necessary is just to select the some material which each exhibits a desired function as the surface member Z2. The shape of the surface member Z2 is not particularly limited, and for example, various shapes such as a wire shape, a granular shape, a belt shape, and a fiber shape can be employed.

  Examples of the pretreatment means 2 include a foreign substance removal processing device that removes dirt and dust attached to the outer peripheral surface of the core material Z1, and degreasing that removes oil and fat components such as mineral oil attached to the outer peripheral surface of the core material Z1. Examples of the processing apparatus or various apparatuses such as a surface processing apparatus performed to improve the adhesion between the outer peripheral surface of the core material Z1 and the surface member Z2 can be given. Further, as the pretreatment means 2, a single device selected from a foreign matter removal treatment device, a degreasing treatment device, and a surface processing treatment device may be adopted, or the manufacturing device 1 may be combined with a plurality of devices. It may be configured. Here, examples of the foreign matter removal processing device include an air processing device that removes dirt and dust attached to the outer peripheral surface by blowing air to the core material Z1, a water washing processing device that removes dirt by washing, and a core material Z1. Examples thereof include a wiping treatment device for wiping off dirt on the outer peripheral surface with a waste cloth or the like. In addition, as a degreasing apparatus, for example, an oil or fat component such as mineral oil adhered to the core material Z1 by immersing the core material Z1 in a degreasing solution such as alcohol, acetone or thinner in a degreasing treatment tank or the like. A solvent degreasing device for removing dirt can be exemplified. In addition to such a solvent degreasing device, a heating degreasing device that removes oil and fat components on the surface of the core material Z1 by applying heat, or a shock wave when a vacuum bubble generated in a liquid by an ultrasonic wave bursts is used. An ultrasonic degreasing device, an alkaline electrolytic degreasing device that removes oil and fat components such as mineral oil attached to the surface of the core material Z1 by electrolysis at a predetermined current density while immersing the core material Z1 in an alkali cleaning solution, Various degreasing devices can be applied. Moreover, as a surface processing apparatus, the blast processing apparatus for improving the unevenness | corrugation of the outer peripheral surface of the core material Z1 can be illustrated, for example. In addition, since the pretreatment means 2 is a means (apparatus) for increasing the adhesion strength between the core material Z1 and the surface member Z2, the manufacturing apparatus 1 according to the present invention does not include the pretreatment means 2. When sufficient adhesion strength between the core material Z1 and the surface member Z2 can be obtained, the pretreatment means 2 can be omitted and the manufacturing apparatus 1 can be configured.

  The surface member disposing means 3 is a device that disposes the surface member Z2 on the outer peripheral surface of the core material Z1 made of a conductive material. The surface member disposing means 3 can employ various devices capable of disposing the surface member Z2 on the outer peripheral surface of the core material Z1, but for example, the surface member Z2 made of a wire is used as the core material Z1. A covering device that covers the outer peripheral surface of the core material Z1 with the surface member Z2 by being wound spirally around the outer peripheral surface can be employed as the surface member disposing means 3. As shown in FIG. 3, the covering device includes a spool 31 around which a wire is wound, and a drive device (not shown) that rotates the spool 31 around the shaft center. The axial center of the spool 31 is formed so as to be hollow, and the core material Z1 can be inserted into the hollow portion. The operation of the covering device will be described. First, the wire (surface member Z2) wound around the spool 31 is pulled out, and the tip of the wire (surface member Z2) is fixed to the surface of the core material Z1. Next, while rotating the spool 31 by the driving device, the core material Z1 is moved at a predetermined speed (moved in the direction along the axis of the spool 31) by a separately provided conveying means (not shown). The wire material which is the surface member Z2 is spirally wound on the outer peripheral surface of the material Z1, and the outer peripheral surface of the core material Z1 is covered with the surface member Z2 made of the wire material as shown in FIG. The surface member Z2 made of a wire wound around the outer peripheral surface of the core material Z1 is appropriately adjusted by adjusting the transport speed (movement speed) of the core material Z1 by the transport means and the rotational speed of the spool 31 (core core). The number of windings of the wire per unit length of the material Z1) can be adjusted.

  The heating means 4 is a device for heating the core material Z1 having the surface member Z2 disposed on the outer peripheral surface. Due to the heat of the core material Z1 heated by the action of the heating means 4, at least one of the facing regions Z3a and Z3b between the surface member Z2 and the core material Z1 is melted, and the surface member Z2 is fused to the core material Z1. It becomes possible to make it.

  In the present embodiment, an electromagnetic induction heating device is employed as the heating means 4. The electromagnetic induction heating device is a kind of heating device used for electromagnetic cookers (IH cooking heaters), high frequency welding, etc., and causes a change in magnetic field (magnetic flux density) by passing an alternating current through the coil. This is a heating device that utilizes the principle of generating an induced current (eddy current) in a conductive substance placed in a magnetic field and generating heat by the resistance of the conductive substance itself. When the electromagnetic induction heating device is used as the heating means 4, the core material Z1 constituting the composite member Z is formed from a conductive material. Further, the surface member Z2 is formed of a material having lower magnetism than the core material Z1. The material having lower magnetism than the core material Z1 is a concept including a material having no magnetism in addition to a material having lower magnetism than the core material Z1. The surface member Z2 may be formed of a material that easily conducts electricity, or may be formed of a material that does not conduct electricity. The core material Z1 is not composed of a single material, but is composed of a plurality of materials (in the case where the core material Z1 is composed by twisting two kinds of wire-shaped metal members, or a wire-shaped metal member and a wire material) In the case where the resin member is formed by twisting the resin member, the material is configured such that at least one kind of material can easily conduct electricity.

  In this way, the core material Z1 is made of a conductive material, and the surface member Z2 is made of a material having a lower magnetic property than the core material Z1, so that the core material Z1 is more core than the surface member Z2 by electromagnetic induction heating by the electromagnetic induction heating device. The amount of heat generated by the material Z1 increases, and the temperature of the core material Z1 becomes higher than the temperature of the surface member Z2. Accordingly, at least one of the facing regions Z3a and Z3b between the surface member Z2 and the core material Z1 (the facing region Z3a of the surface member Z2 with the core material Z1 or the facing region Z3b of the core material Z1 with the surface member Z2) Or both) can be melted. For example, when the melting point of the surface member Z2 is lower than the melting point of the core material Z1, the heat generated by the core material Z1 is transmitted to the surface member Z2, and the surface member Z2 is opposed to the core material Z1 (contact region). Z3a will melt. Further, since the density of the induced current generated in the electromagnetically heated core material Z1 is higher as the surface is closer to the surface from the center of the core material Z1, the surface is heated faster than the inside of the core material Z1 ( Will be heated in a concentrated manner). Therefore, when the melting point of the core material Z1 is lower than the melting point of the surface member Z2, the surface of the core material Z1 heated in a concentrated manner (the region (contact region) Z3b facing the surface member Z2 in the core material Z1) Will melt. Here, by setting the frequency of the current flowing in the electromagnetic induction heating device (AC current flowing in the coil) high, the heat generating parts in the core material Z1 can be collected on the surface, and conversely the current frequency is lowered. By setting, the inside of the core material Z1 can also generate heat uniformly. Therefore, it is preferable to configure the electromagnetic induction heating device so that the frequency of the current flowing through the electromagnetic induction heating device can be appropriately changed.

  As the electromagnetic induction heating device, for example, as shown in FIG. 4, a hollow cylindrical shape can be preferably used. Electromagnetic induction heating is performed by placing a core material Z1 having a surface member Z2 disposed on the outer peripheral surface in a space 41 at the center of the hollow cylindrical electromagnetic induction heating device. After completion of the electromagnetic induction heating for a predetermined time, the core material Z1 in which the surface member Z2 is disposed on the outer peripheral surface is taken out from the space 41 in the center of the hollow cylindrical electromagnetic induction heating device, or electromagnetic induction is performed. By stopping the heating device, the temperature of the surface member Z2 and the core material Z1 is decreased, the dissolved region is solidified, and the surface member Z2 and the core material Z1 are fixed to each other.

  In the composite member Z manufacturing apparatus 1 according to the above embodiment, the surface member disposing means 3 disposes the surface member Z2 having a lower magnetic property than the core material Z1 on the outer peripheral surface of the core material Z1 made of a conductive material. The core material Z1 is electromagnetically induction heated from the outside of the surface member Z2, and at least one of the facing regions Z3a and Z3b between the surface member Z2 and the core material Z1 is melted by the heat of the heated core material Z1, Since the heating means 4 for fusing the member Z2 to the core material Z1 is provided, the shape of the outer surface of the surface member Z2 disposed on the surface of the core material Z1 is not impaired by heat melting. It becomes possible to reliably fuse and fix the surface member Z2 on the outer peripheral surface of the core material Z1. Therefore, a function that combines the material characteristics of the member (surface member Z2 fixed on the outer peripheral surface of the core material Z1) disposed on the outer side of the composite member Z and the shape characteristics of the outer surface of the composite member Z. Can be applied to the composite member Z. For example, the composite member Z produced by spirally winding a wire made of a corrosion-resistant material as the surface member Z2 on the outer peripheral surface of the core material Z1 made of a long metal wire by the production apparatus 1 In addition to the corrosion resistance which is a material characteristic of the surface member Z2, it has an excellent flexibility function obtained from the shape characteristics of the outer surface of the composite member Z. That is, it becomes more excellent in flexibility than the composite member Z manufactured by simply applying the corrosion resistant coating to the outer peripheral surface of the core material Z1. Further, when lubricating oil is infiltrated into the outer surface of the composite member Z obtained in this way, the lubricating oil enters the recesses Z4 (see FIG. 2) on the outer surface of the composite member Z. This composite member Z can exhibit the function of being able to hold the lubricating oil for a long period of time.

  Further, even when the surface member Z2 is selected on the outer peripheral surface of the core material Z1 as the surface member Z2, a material that is difficult to be generated in a liquid form is used in the form of a wire or particles. By forming the surface member Z2 on the surface, such a surface member Z2 can be fused and fixed onto the outer peripheral surface of the core material Z1.

  Moreover, in the said embodiment, the hollow cylindrical type thing (thing of a cross-sectional ring form) is employ | adopted as an electromagnetic induction heating apparatus (heating means 4), and the core by which the surface member Z2 was arrange | positioned on the outer peripheral surface The material Z1 is arranged in the central space 41 to perform electromagnetic induction heating. That is, since it is configured to surround the surface member Z2 disposed on the outer peripheral surface of the core material Z1 and perform electromagnetic induction heating, heat is uniformly emitted from the entire outer peripheral surface of the core material Z1, The entire region to be dissolved (a region Z3a facing the core member Z1 in the surface member Z2 or a region Z3b facing the surface member Z2 in the core member Z1 or both) is uniformly thermally melted. It becomes possible. As a result, the surface member Z2 and the core material Z1 disposed on the outer peripheral surface of the core material Z1 can be joined with a uniform fixing force without unevenness.

  Further, in the manufacturing apparatus 1 for such a composite member Z, electromagnetic induction can be achieved by selecting materials for the surface member Z2 and the core material Z1 so that the melting point of the surface member Z2 is lower than the melting point of the core material Z1. The heat of the core material Z1 to be heated makes it possible to melt the facing region (contact region) Z3a of the surface member Z2 with the core material Z1 before the core material Z1, so that the shape of the core material Z1 is heated. Only the surface member Z2 can be reliably melted without being damaged by melting, and the surface member Z2 can be fused and fixed on the outer peripheral surface of the core material Z1.

  Moreover, in the manufacturing apparatus 1 of such a composite member Z, for example, as shown in FIG. 5, the core material Z1 is formed so that the center portion Z11 and the surface portion Z12 are different materials, and the surface of the core material Z1 You may comprise so that the surface part Z12 of the core material Z1 corresponding to the opposing area | region Z3b with respect to the member Z2 may be heat-dissolved by heating. Even in such a configuration, the surface portion Z12 of the core material Z1 is thermally melted and then cooled and solidified, so that the surface member Z2 and the core material Z1 can be firmly fused (fixed). .

  Specifically, for example, the central portion Z11 of the core material Z1 is formed of a material having a relatively high melting point such as iron or stainless steel, and the surface portion Z12 of the core material Z1 is zinc or tin having a lower melting point than the central portion Z11. It forms with metal materials, such as. When such a core material Z1 is heated by the heating means 4, the surface portion Z12 having a melting point lower than that of the central portion Z11 is first melted by heat, and the material of the surface portion Z12 is cooled and solidified. Thus, the surface member Z2 (surface member Z2 disposed on the surface portion Z12 of the core material Z1) disposed on the outer peripheral surface of the core material Z1 is fixed to the core material Z1. When the core material Z1 has such a configuration, the material of the surface member Z2 may be selected so that the region Z3a facing the core material Z1 of the surface member Z2 is thermally melted, or the core material of the surface member Z2 The surface member Z2 may be selected so that the region Z3a facing the Z1 is not thermally melted, and the range of material selection for the surface member Z2 is widened.

  Further, the core material Z1 shown in FIG. 5 has a two-layer structure including a central portion Z11 and a surface portion Z12. For example, as shown in FIG. The core material Z1 may be configured to include a plurality of layers Z11a, Z11b, and Z11c. Further, as the core material Z1, the material of the surface portion Z12 may be configured to have a melting point lower than that of the central portion Z11, and the core material Z1 may be configured to have conductivity as a whole. The surface portion Z12 may be composed of a conductive material, or the center portion Z11 may be composed of a conductive material, and the surface portion Z12 may be composed of a material that is difficult to conduct electricity. Good.

  The manufacturing apparatus 1 for manufacturing the composite member Z according to the present invention has been described above, but the specific configuration is not limited to the above embodiment. For example, in the above embodiment, the electromagnetic induction heating device (heating means 4) employs the hollow cylindrical shape shown in FIG. 4, but is not particularly limited to such a configuration, and the surface member Any shape may be used as long as it can generate an eddy current in the core material Z1 by changing the magnetic field (magnetic flux density) with respect to the core material Z1 on which Z2 is disposed. For example, a plate-shaped material used for an electromagnetic cooker (IH cooking heater) is adopted as an electromagnetic induction heating device, and a core material Z1 having a surface member Z2 disposed in the vicinity of the plate-shaped electromagnetic induction heating device is used. You may comprise so that the core material Z1 may be heated by arrange | positioning.

  Moreover, in the said embodiment, although the electromagnetic induction heating apparatus is employ | adopted as the heating means 4, it replaces with this electromagnetic induction heating apparatus, for example, an electrode is connected to the predetermined two places of the core material Z1, and the said electrode You may comprise so that the core material Z1 may generate | occur | produce a Joule heat by sending an electric current in between.

  In the composite member manufacturing apparatus 1 in the above embodiment, the surface member Z2 is heated by the heating means 4 after the surface member Z2 is disposed on the outer peripheral surface of the core material Z1, thereby the surface member Z2 is heated to the core material Z1. For example, after the core material Z1 is heated by the heating means 4 in advance, the surface member disposing means 3 is attached to the outer peripheral surface of the heated core material Z1. You may comprise the manufacturing apparatus 1 so that Z2 may be arrange | positioned. In the case of adopting such a configuration, as the heating means 4, in addition to the above-described electromagnetic induction heating device and a device for heating the core material by flowing an electric current between electrodes connected to two predetermined positions of the core material, A hot air generator, an infrared heating device, a far infrared heating device, or the like that heats the core material by applying hot air to the core material can also be used, and the versatility of the manufacturing apparatus 1 can be enhanced. Even when such a configuration is adopted, when the surface member Z2 is disposed on the outer peripheral surface of the core material Z1, it is disposed on the outer peripheral surface of the core material Z1 by the heat of the core material Z1 that has been heated in advance. At least one of the facing regions Z3a and Z3b of the surface member Z2 and the core material Z1 (the facing region Z3a of the surface member Z2 with the core material Z1 or the facing region Z3b of the core material Z1 with the surface member Z2 or Both of them can be thermally melted, and a composite member in which the surface member Z2 is fixed to the outer peripheral surface of the core material Z1 can be manufactured.

  Moreover, in the said embodiment, as shown in the schematic block diagram of FIG. 7, you may comprise the manufacturing apparatus 1 so that the adhesive bond layer formation means 5 may be provided. This adhesive layer forming means 5 has an adhesive having a melting point lower than the melting point of the core material Z1 in advance on the outer peripheral surface of the core material Z1 before the surface member Z2 is disposed on the outer peripheral surface of the core material Z1. It is a means for coating, and includes a coating device 51 and a drying device 52. The coating device 51 is a device that applies an adhesive having a melting point lower than the melting point of the core material Z1 to the outer peripheral surface of the core material Z1. As a specific method of applying the adhesive to the outer peripheral surface of the core material Z1, an adhesive layer is sprayed on the outer peripheral surface of the core material Z1 by spraying the adhesive atomized by a spray gun or the like onto the outer peripheral surface of the core material Z1. A method of forming (spray method), a method of dipping the core material Z1 in a storage tank in which the adhesive is stored, and forming an adhesive layer on the outer peripheral surface (outer surface) of the core material Z1 (dipping method), etc. Can be adopted. The adhesive used in the adhesive layer forming means 5 is not particularly limited as long as the surface member Z2 can be maintained at a desired position on the outer peripheral surface of the core material Z1 by the adhesive force. The melting point of the agent may be approximately equal to or lower than the melting point of the surface member Z2, or the adhesive may have a melting point equal to or higher than the melting point of the surface member Z2. Here, when an adhesive whose melting point is larger than the melting point of the surface member Z2 is adopted, an adhesive having high thermal conductivity capable of efficiently transmitting the heat of the heated core material Z1 to the surface member Z2. Is preferably selected. Moreover, what has various functions can be selected as an adhesive agent. For example, in the case where an adhesive having a high heat insulating property is adopted, in addition to the function exhibited by the core material and the function exhibited by the surface member, a composite member further having a heat insulating function exhibited by the adhesive can be manufactured. It becomes possible. Further, as the adhesive, a hot melt adhesive mainly composed of a thermoplastic resin can also be used. When this hot melt adhesive is used, the hot melt adhesive is heated and melted and then applied to the outer peripheral surface of the core material Z1.

  The drying device 52 is a device that dries the adhesive applied to the outer peripheral surface of the core material Z1. For example, the drying device 52 applies a predetermined amount of air to the core material Z1 to which the adhesive is applied by an air blower. Configured to perform drying. In addition, you may comprise so that an air blower may be provided with a heat generating body, and you may comprise so that warm air may be sprayed with respect to the core material Z1 to which the adhesive agent was apply | coated. In addition, when drying an adhesive agent by natural drying, the manufacturing apparatus 1 which concerns on this invention can be comprised, without providing this drying apparatus 52. FIG.

  As described above, when the manufacturing apparatus 1 is configured to include the coating apparatus 51, the core material Z1 is heated by electromagnetic induction from the outside of the surface member Z2, for example, as the surface member Z2, than the melting point of the core material Z1. When a member having a low melting point is used and the adhesive used in the adhesive layer forming means 5 is one whose melting point is substantially equal to or less than that of the surface member Z2, the core material Z1 is electromagnetically induced. By heating, the facing region Z3a of the surface member Z2 with respect to the core material Z1 and the adhesive interposed between the surface member Z2 and the core material Z1 can be dissolved, making the surface member Z2 stronger and more robust to the core material. It can be fixed to Z1. Specifically, as the surface member Z2, a wire rod that is spirally wound around the outer peripheral surface of the core material Z1, or a granular or fibrous material that is disposed on the outer peripheral surface of the core material Z1 by spraying. When a member is used, the melted adhesive enters the gap between adjacent wire and granular members, so that the surface member Z2 can be securely fixed to the core material Z1. It becomes. Further, when a member having a melting point higher than that of the core material Z1 is used as the surface member Z2, an adhesive interposed between the surface member Z2 and the core material Z1 is obtained by heating the core material Z1. It melt | dissolves and it becomes possible for this melt | dissolved adhesive agent to approach into the clearance gap between the surface members Z2 arrange | positioned adjacently, and to adhere the surface member Z2 and the core material Z1 reliably. Further, even when an adhesive having a melting point higher than that of the surface member Z2 is used, the heat of the core material Z1 is transmitted to the surface member Z2 through the adhesive layer, so that the surface member It is possible to dissolve the facing region 13a of the core material Z1 in Z2, and the surface material Z2 is fixed on the core material Z1 through the adhesive layer by cooling the dissolved facing region 13a. be able to.

  Further, since the adhesive layer forming means 5 is configured to include the drying device 52 that dries the adhesive applied to the outer peripheral surface of the core material Z1, the surface in a state where the adhesive strength of the adhesive is lost. The member Z2 can be disposed on the outer peripheral surface of the core material Z1. The surface member Z2 may be disposed on the outer peripheral surface of the core material Z1 even in the state where the adhesive force of the adhesive exists, that is, in the state where the adhesive is not dried, but the adhesive is not dried. When the surface member Z2 is disposed on the outer peripheral surface of the core material Z1 in a liquid or semi-liquid state, the liquid (or semi-liquid) adhesive is disposed around the disposed surface member Z2. Ooze out and the adhesive may remain on the outer surface of the finally obtained composite member Z. Alternatively, the liquid (or semi-liquid) adhesive may flow along the outer peripheral surface of the core material Z1, and the adhesive may not be distributed with a uniform thickness on the outer peripheral surface of the core material Z1. In such a case, when the core material Z1 is heated, for example, when the surface area Z3 is fixed to the core material Z1 by melting the facing region Z3a of the adhesive and / or the surface material Z2 with the core material Z1, There is a possibility that the adhesive force between the surface member Z2 and the core material Z1 may be reduced in a portion where the adhesive is thinly applied to the surface of the core material Z1. On the other hand, in the previous stage of disposing the surface member Z2 on the outer peripheral surface of the core material Z1, the adhesive applied to the outer peripheral surface of the core material Z1 is dried, and then the surface member Z2 is applied to the outer peripheral surface of the core material Z1. In the case of disposing, it is possible to effectively prevent the adhesive leaching and the adhesive thickness distribution as described above from being uneven and adhere to the outer surface of the finally obtained composite member Z. It is possible to reliably prevent the agent from remaining and the occurrence of a portion where the fixing force between the surface member Z2 and the core material Z1 is reduced.

A core material winding device that winds spirally around the outer peripheral surface and covers the outer peripheral surface of the core material Z1 with the surface member Z2 may be employed as the surface member disposing means 3. When the belt-shaped surface member Z2 is wound around the core material Z1, the surface member Z2 may or may not overlap with the winding pitch. Here, when the core material Z1 has a rod-like shape with a relatively large diameter, the belt-shaped surface member Z2 is spirally wound around the outer peripheral surface of the core material Z1 while rotating the core material Z1 in this way. By adopting the core material winding device, the surface member Z2 can be efficiently disposed on the core material Z1. Moreover, it is possible to employ as the surface member disposing means 3 a spraying device that covers the outer peripheral surface of the core material Z1 with the surface member Z2 by spraying the granular or fibrous surface member Z2 onto the outer peripheral surface of the core material Z1. it can. When the granular or fibrous surface member Z2 is arranged on the outer peripheral surface of the core material Z1 using such a spraying device, for example, the outer surface of the core material Z1 is charged so as to have a positive charge. The granular or fibrous surface member Z2 is charged so as to have a negative charge, and the granular or fibrous surface member Z2 is sprayed and attached to the outer peripheral surface of the core material Z1. preferable.
