Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixed flow line device for positioning a left body and a right body of a vehicle body on the same line.

[0002]

2. Description of the Related Art A conventional vehicle body manufacturing line is shown in FIG.
The one shown in 7 is in practical use. That is, as shown in FIG. 5, the vehicle body manufacturing line is provided with a left body line 50L and a right body line 50R. A plurality of jigs for positioning the left body LB of the vehicle body are arranged on the left body line 50L as shown in FIG. The plurality of jigs are formed of hangers or the like, and the upper left jig 1 that supports the upper portion of the left body LB.
L to 7L, a left intermediate jig 8L to 15L configured by a locator or the like for positioning the intermediate portion of the left body LB, and a lower jig 16L to 23L configured by a piece receiver or the like for positioning the lower end portion of the left body LB. Become.

A plurality of jigs for positioning the right body RB of the vehicle body are arranged on the right body line 50R as shown in FIG. Similarly, the plurality of jigs similarly include upper right jigs 1R to 7R configured by hangers and the like to support the upper portion of the right body RB, and right intermediate jig 8R configured by a locator and the like to position an intermediate portion of the right body RB. ~
15R and lower jigs 16R to 23R for positioning the lower end of the right body RB, which are composed of a piece receiver and the like. That is, since the left body LB and the right body RB are left / right different, the left and right body lines 50L and 50R have the same number of jigs corresponding to the left and right inverted positions. .

[0004]

However, in such a conventional vehicle body manufacturing line, the left body LB is used.
Left body line 50L for positioning the right body LB, and right body line 50 for processing the right body LB
R and R are provided separately. Therefore, each line 50
A space is required for each of L and 50R, which not only lengthens the line space but also reduces the production efficiency for the line space.

The left-side body LB and the right-side body RB are different in right and left but have the same size. Therefore, the same number of jigs 1L to 23L and 1R to 23R are required in the lines 50L and 50R, respectively. Becomes Therefore, the number of jigs becomes enormous, which is one of the causes of increasing the equipment cost.

The present invention has been made in view of such conventional problems, and it is an object of the present invention to provide a mixed flow line device in which the line space is reduced and the facility cost is reduced. .

[0007]

In order to solve the above problems, according to the present invention, a body left side jig used only for the left body of the vehicle body and a right side body jig are used. The jig for the right side of the body and the common jig that is commonly used for the left and right bodies are arranged on the same line.

[0008]

In the above structure, when the left side body of the vehicle body is positioned, the body left side jig and the common jig are used, and when the right side body of the vehicle body is positioned, the body right jig and the common jig are used. Use and. Therefore, since the common jig is used for both the left body and the right body, the number of jigs required is reduced as compared with the case where the dedicated jig is provided for each side body.

In the present embodiment having the above configuration, the upper part, the intermediate part, and the lower end part of the left body LB and the right body RB are respectively positioned by the jigs described below. (1) Upper part of left body LB: common upper jigs 101N, 102N, 104N,
106N, 107N Upper left jig 105L Middle part: Left middle jig 109L, 110L, 112L,
113L Lower end: common lower jigs 121N, 122N lower left jigs 116L, 119L, 123L, 125L,
126L (2) Right body RB Upper part: Common upper jig 101N, 102N, 104N,

That is, in this embodiment, the left body LB and the right body RB, which are left-right handed, are positioned by 17 jigs respectively, but 5 common upper jigs 101N, 102N, 104N, 106N, 1
07N and the two common upper jigs 121N and 122N are shared by the left body LB and the right body RB. Therefore, when the lines of the left body LB and the right body LB are separately provided, 17 × 2 = 34 jigs are required, whereas 34-7 = 27 jigs are sufficient. As a result, the number of required jigs can be reduced and the equipment cost can be reduced. Further, since the line for the left body LB and the line for the right body RB can be positioned by the single mixed flow line 100, a dedicated line space for each of the side bodies LB and RB is not required, and the line space is short and small. Can be realized.

[0017]

As described above, according to the present invention, the body left side jig used only for the left side body, the body right jig used only for the right side body, and the left and right side bodies The common jig used in common is arranged on the same line. Therefore, it is possible to reduce the number of jigs corresponding to the number of shared jigs and reduce the equipment cost, as compared with the conventional case where the left and right bodies are positioned on separate lines.

Further, the dedicated line space for each of the left and right bodies is not required, and the line space can be shortened, whereby the production efficiency for the space can be improved. In addition, since the line space can be reduced and the lines can be collectively arranged, it is possible to suppress the decentralization of maintenance personnel in the event of a failure.
