In the above-mentioned prior art, since many parts are mounted inside the vehicle during the outfitting work,
An operator brings in parts in a narrow car and manually installs each item. Further, since it is difficult to bring equipment or machinery into the vehicle, automation and mechanization are difficult. Therefore, the workability is poor and much labor and time are required. In addition, there are many parts to be mounted on the ceiling or under the floor in the vehicle, and the work is performed upwards, and the work posture is not good, so the efficiency cannot be improved. In recent years, an outfitting method for rotating the entire vehicle body to improve the work posture has been performed, but it is necessary to install a dedicated jig on the vehicle body.

Further, since the work of outfitting is performed on the box-shaped vehicle body, the work space is narrow, and the workable parts are limited at the same time. Therefore, the number of production days becomes long, which is an obstacle in improving the production efficiency. .

It is an object of the present invention to provide a vehicle production method capable of improving workability in outfitting work.

[0007]

In order to achieve the above-mentioned object, a plurality of blocks constituting a vehicle are combined and joined together and manufactured individually, and each block is subjected to an outfitting work, and the outfitting is carried out. This is to combine and join a plurality of blocks after the work is completed.

[0008]

[Operation] Since the outfitting work is individually performed on the plurality of blocks, the work space can be sufficiently secured, and the carry-in of the outfitting equipment is not restricted, and the workability is greatly improved. You can The plurality of blocks are combined and joined after the outfitting work is completed to complete the vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle production method of the present invention will be described below with reference to FIGS. In the figure, the vehicle is composed of main components of an underframe block 1, a side block L2, a side block R3, a roof block 4, a gable block F5, and a gable block R6, and is basically a hexahedron. The underframe block 1, the side block L2, the side block R3, the roof block 4, the wife block F5, and the wife block R6 are manufactured by independent production lines. However,
Since the wife block F5 and the wife block R6 are smaller than the other blocks and the number of fittings attached is small, they are manufactured in one line. More specifically, the underframe block 1 is formed by the underframe block assembly line 7,
The side block L2 is formed by the side block L assembly line 8, the side block R3 is formed by the side block R assembly line 9, and the roof block 4 is formed by the roof block assembly line 10.
Each is produced by. The wife block F5 and the wife block R6 are manufactured by the one wife block assembly line 11 as described above. Each of the block assembly lines is basically a can making line 12 and a block fitting line 1
3, and a block total assembly line is provided at the final portion of each assembly line. In the can manufacturing line 12 of each of the assembling lines 7, 8, 9, 10, and 11, each block is made of a plate member such as a flat plate member, a shape member, and a coil member, and a plate member such as an outer plate cut and formed. Jig for positioning, such as underframe jig 16 as shown in FIG. 3,
After that, each bone member and the plate material are joined by an automated spot welding machine or the like. Each block is a panel having a simple structure as a whole. The underframe block 1, the side block L2, the side block R3, the roof block 4, the wife block F5, and the wife block R6 thus manufactured are then sent to the block outfitting line 13.
Underframe block assembly line 7 of block outfitting line 13
The underframe block 1 works on both the bottom surface and the floor surface of the vehicle, and main fittings such as underfloor pipes, air reservoirs and center pins, and floor coverings are sequentially installed. . However, large electrical appliances are installed after the total assembly in consideration of deformation of the underframe block 1. The side blocks L2 and R3 are the side block assembly lines 8 and 9 of the block outfitting line 13, and the outfitting work is performed independently. At this time, the side block L2 and the side block R3 are suspended by a suspending tool 17 with respect to a rail installed in accordance with the work advancing direction of the production line as shown in FIG. 4, and the outfitting work is performed in this state. Be seen. Therefore, all the outfittings such as interior materials, window devices, luggage racks, seats and door devices are sequentially attached to the vertical side surface of each block, and the table lifter 18 and the like are used for the work. The outfittings are stored on both sides of each block so as to correspond to the installation surface of each block, so that the moving distance can be shortened as much as possible. The roof block 4 is a roof block assembly line 10 of the block outfitting line 13 to which all indoor-side ceiling-installed parts are attached and also out-door-side outfitting parts. Also, the insulation coating on the roof top will be done in accordance with the outfitting work. The air conditioner is installed on the roof block 4 after the assembly is completed in consideration of deformation. The wife block F5 and the wife block R6 are the wife block assembly line 11 of the block outfitting line 13, on which the interior material and other outfittings are attached. Since the gable block F5 and the gable block R6 have a small number of outfittings, they are manufactured in one line so as to be synchronized with the manufacturing process of other blocks.

As described above, each block is sent to the next block total assembly line 14 after the fittings except for some heavy ones are attached. Then, side blocks L2 and side blocks R3 are placed upright at both widthwise positions of the underframe block 1, and wife blocks F5 and wife blocks R6 are placed upright at the longitudinal end positions of the underframe block 1. , Join these. Thereafter, the roof block 4 is placed on the upper side of the side block L2, the side block R3, the end block F5, and the end block R6 to join them, and the completed vehicle 15 is completed.

According to such a production method, first, the outfitting work can be performed for each block assembled in the can making line 12. Therefore, as compared with the case where the conventional fitting operation is performed on the box-shaped structure, a sufficient working space can be secured, so that workability can be improved. In addition, since each block is a panel with a simple structure, you can work even if it is laid flat or suspended, and compared to the conventional outfitting method, mainly downward work and sideways work, so from this point Also, the workability can be improved and the efficiency can be improved. If the block is rigged as shown in FIG. 4, it is possible to perform the rigging work on both sides of the block at the same time while securing a sufficient working space as described above. Further, the efficiency can be improved. Further, since the block is hung and supported, it is possible to prevent deformation without applying unnecessary bending force to the block. By the way, when the block is suspended and the outfitting work is performed, the position of the center of gravity of the block changes as the outfitting is installed, so that the block tilts. In order to prevent such a phenomenon, it is possible to install a stopper for preventing the movement of the block at each block suspension position. The stopper may have a structure in which a roller or the like formed of an elastic body is installed so that the block can be smoothly moved within the line and the block is not damaged.

Further, since the can making line 12 and the block fitting line 13 simultaneously perform the can making work and the fitting work for each block, the hand waiting time during each work can be reduced as compared with the conventional method. The work schedule can be greatly shortened.

Further, particularly in the can manufacturing line, since each block is a panel having a simple structure, the work can be automated by using various automatic machines.

Next, another vehicle production method of the present invention will be described with reference to FIG. In this embodiment, the side block L2
The side block R3 and the side block R3 are suspended back to back in a state where the surfaces serving as the outer side surfaces of the vehicle face each other, and the cushion material 21 is arranged between the two to perform the outfitting work.

According to such a production method, even if the center of gravity of each block changes due to mounting of the seat 19 and the luggage rack 20 having a comparatively heavy weight on each block, the balance is maintained between the two blocks. Can be prevented. Therefore, it is possible to prevent the workability from being lowered due to the inclination of the block by a simple method.

By the way, although the above-mentioned embodiment shows an example of a stainless steel vehicle, the present invention is not limited to this, and the same effect can be obtained by applying it to a light alloy vehicle or a steel vehicle. Can be achieved. In addition, the above-mentioned embodiment is an example of a stainless steel vehicle, and its production line does not include a coating line, but in the case of a vehicle that requires painting such as a light alloy vehicle or a steel vehicle, A coating line will be formed between the can line and the block outfitting line. Also in this painting line, since each block is formed in a panel shape as a whole, it is easy to automate puttying and painting work.

The present invention is also applied to a container, an automobile, a building, a ship, etc., in which fittings, that is, interior parts are installed in advance in each of a plurality of blocks into which the basic structure is divided, and these blocks are combined and joined. It is possible.
