Upon the development of tractor, there it to equipped with a prototype fuel tank for the engine. When manufacturing a product with a small number of manufactured items such as prototypes, the use of a manufacturing method that requires a mold for molding would be uneconomical for the manufacture of the mold. as a production unit, not, there to employ a powder lamination method of laminating a resin powder by laser sintering. When the powder lamination method is adopted, there is a limit to the size of products that can be produced by the powder lamination method. Therefore, a divided product obtained by dividing a desired product into a plurality of parts is produced by the powder lamination method, and manufactured by the powder lamination method. A desired product may be obtained by bonding a plurality of divided products.

When an object to be bonded such as a divided product is bonded manually, defective bonding is likely to occur.
In other words, the pressure-bonding unevenness occurs because the bonded portion of the pair of objects to be bonded is pressed by pressing while supporting the pair of bonded objects to be bonded by hand. However, uneven adhesion or insufficient adhesion may occur.
In particular, when the manufacturing method described in Patent Document 1 is adopted, since the bonded portions of a pair of objects to be bonded are pressed together in a state where a heating element is interposed, it is difficult to perform an appropriate pressure welding operation and uneven pressure welding is not possible. If it is easy to occur and insufficient pressure contact occurs, heat transfer from the heating element to the bonded portion is deteriorated, and insufficient melting tends to occur, resulting in uneven welding or insufficient welding.

  FIG. 18 is an explanatory diagram showing a pressing method that has been conceived as being capable of pressing an object to be bonded while hardly causing uneven pressing. In this pressure contact method, the casing 110 is integrally formed in the vicinity of the bonding portions 101a and 102a of the bonding objects 101 and 102, and the bonding portions 101a and 102a are brought into contact with each other. A clip 111 is attached to the housing 110 of the one 101 and the housing 110 of the other 102, and the housing 110 of the pair of objects to be bonded 101 and 102 is sandwiched by the clip 111, whereby a pair of objects to be bonded 101, 102 is obtained. The adhesive portions 101a and 102a are pressed against each other.

  When this pressure welding method is adopted, it is disadvantageous in terms of production cost and labor because it is necessary to provide the case 110 and to remove the case 110 after the bonding of the object to be bonded is completed. Tended to be.

The fuel tank 100 is equipped to store engine fuel in the tractor. The fuel tank 100 is manufactured by bonding divided tanks 101 and 102 obtained by dividing the fuel tank 100 into two. Each of the divided tanks 101 and 102 is manufactured by a powder laminating method in which resin powder is laminated by laser sintering, and is a resin tank made of a thermoplastic synthetic resin. FIG. 17 is a cross-sectional view showing the bonding portions 101a and 102a of the divided tanks 101 and 102. FIG. As shown in this figure, the adhesive portion 101a of one of the divided tanks 101 is configured to include a recessed portion 103 provided over the entire length of the adhesive portion 101a. The bonding portion 102a of the other split tank 102 includes a chamfered portion 104 provided over the entire length of the bonding portion 102a. The pair of split tanks 101 and 102 are connected by an inlay structure in which the other adhesive portion 102a enters the recessed portion 103 of one adhesive portion 101a. The chamfered portion 104 of the other split tank 102 forms a space for accommodating the heating element 105 between the one adhesive portion 101a and the other adhesive portion 102a. The lateral width W of the recessed portion 103 in the tank inner / outer direction is set to be relatively larger than the outer diameter of the heating element 105. That is, even if the heat generating body 105 is deformed due to the expansion due to the thermal expansion, the heat generating body 105 is inserted into the recessed portion 103 so that the heat generating body 105 does not break through the bonding portion 101a and the bonding portion 102a and go outside. The width is set to a size that can be accommodated.

Below, a pair of adhesion | attachment target object is called the division tanks 101 and 102, and is demonstrated.
As shown in FIGS. 15A and 15B, one of the divided tanks 101 is disposed between the pair of first supports 11 and 12 in a posture in which the bonding portion 101a faces the second holding mechanism 20, and is movable. The first support 12 is moved toward the fixed first support 11. The sandwiching action portions 13a of the plurality of sandwiching bars 13 of the first support bodies 11 and 12 are in contact with the outer peripheral surface of the split tank 101, and the plurality of sandwiching bars 13 of the first support bodies 11 and 12 are split tanks. When a pressing operation is performed against the clamping spring 16 by the contact reaction force from 101, the operation knob 68 of the positioning mechanism 60 is rotated to the working side. Then, the positioning mechanism 60 is switched to the positioning operation state, and the movable first support 12 is fixed to the frame 1 by the positioning bar 64 so as not to be returned by the clamping reaction force. One of the first supports 11 is a fixed type, and the movable first support 12 is fixed to the frame 1 by the positioning mechanism 60, so that the first support 11 contacts the divided tank 101 of each of the first supports 11 and 12.

When held by the holding mechanism 10, the divided tank 101 can be held while the posture is determined by the mounting table 40, and the posture of the divided tank 101 when the divided tank 101 is held by the first holding mechanism 10 is changed to the bonding portion. The operation can be easily set to a posture in which the bonding surface of 101a becomes a horizontal surface and allows easy bonding with the divided tank 102 with high accuracy.

  Furthermore, one side surface of the reference plate is brought into contact with the adhesive surface of the adhesive portion 101a of the divided tank 101, and the other side surface of the reference plate is brought into contact with the frame body of the frame 1. If the posture determination is also employed, the posture determination of the divided tank 101 when the divided tank 101 is held by the first holding mechanism 10 can be performed with higher accuracy.

  When the first holding mechanism 10 holds the divided tank 101, the other divided tank 102 is overlaid on the divided tank 101 held by the first holding mechanism 10 as shown in FIG. At this time, the adhering portions 101a and 102a of the two divided tanks 101 and 102 are aligned so as to fit together, and the heating element 105 is sandwiched between the adhering portion 101a of the divided tank 101 and the adhering portion 102a of the divided tank 102. .

Due to the reaction force, it is pushed against the holding spring 16. When each second support 21 is positioned at a position immediately above the first support 11 or the first support 12, the positioning means 80 of each second support 21 is automatically switched to the positioned state, and the second support 21 is fixed to the first support 11 or the first support 12 by a latch 82 so as not to be returned by the clamping reaction force. Each second support 21 is fixed to the first support 11 or the first support 12, so that a plurality of sandwiching bars 23 that are in contact with the divided tank 102 of each second support 21 are sandwiched by the sandwiching spring 16. The second holding mechanism 20 is held against the divided tank 102 of one second support body 21 and the second holding mechanism 21 is pressed against the divided tank 102 and the other second support body 21. The divided tank 102 is held by the plurality of holding bars 23 in contact with the divided tank 102 and held in an adhesive posture.

  When the second holding mechanism 20 holds the divided tank 102, the welding control device 50 is turned on. Then, the welding control device 50 operates based on a program inputted in advance to control energization of the heating element 105, and the heating element 105 has an appropriate heating temperature and heating time corresponding to the material of the divided tanks 101 and 102. The heating element 105 is caused to generate heat while adjusting the heat generation temperature and the heat generation time so as to generate heat.

  When melting due to heat generation of the heating element 105 occurs in the bonding portions 101a and 102a of both the divided tanks 101 and 102, the pressure contact lever 33 of the moving operation mechanism 30 is rotated to the pressure contact side. Then, the moving operation mechanism 30 is actuated, the second holding mechanism 20 is moved closer to the first holding mechanism 10 by the pressure contact spring 31, and the adhesive portions 101 a and 102 a of both the divided tanks 101 and 102 are pressed to contact each other. , 102 are bonded together by welding.

  At this time, if the first brake lever 71 is operated to the on position [ON], the first brake means 70 enters the on state and the friction brake is applied to the holding bar 13 of the fixed first support 11. . If the 2nd brake lever 91 is operated to the entry position [ON], the 2nd brake means 90 will be in an entry state, and a friction brake will be applied to the clamping bar 23 of one 2nd support body 21. FIG. Accordingly, the holding bar 13 holding the holding tank 13 of the fixed first support 11 is fixed to the first support 11 by the first brake means 70 in the holding state, and the second bar of the first support 11 is fixed. The sandwiching bar 23 that is sandwiched between the split tanks 102 of the support 21 is fixed to the second support 21 by the second brake means 90 in the sandwiched state, and the bonding portions 101a of the split tanks 101 and 102 are fixed. It is possible to prevent the two split tanks 101 and 102 from being displaced due to the sandwiching bars 13 and 23 being displaced due to the pressure contact operation of 102a.

  When the two split tanks 101 and 102 are bonded, the second support 21 positioned above the movable first support 11 is released from the other second while the fixing to the first support 11 by the positioning means 80 is released. The movable first support 12 is moved away from the support 21, and the movable first support 12 is moved away from the fixed first support 11 in a state where the fixing to the frame 1 by the positioning mechanism 60 is released. Then, the first holding mechanism 10 and the second holding mechanism 20 release the holding of the fuel tank 100, and the fuel tank 100 can be taken out from the manufacturing apparatus.

  When the fuel tank 100 is taken out from the manufacturing apparatus, the portion that is sandwiched between the adhesive portions 101a and 102a of the heating element 105 and embedded in the peripheral wall portion of the fuel tank 100 is placed in the peripheral wall portion of the fuel tank 100. The portion that is left between the bonding portions 101a and 102a of the heating element 105 and that is outside the tank from the peripheral wall portion of the fuel tank 100 is cut out and removed.
