Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for transporting vehicles in a front-lease pension assembly line where two different tl DA vehicles with alignment r to play.

(Prior art) Due to differences in the construction of front suspension barrels, some vehicles require alignment adjustment with the frame in its normal state (hereinafter referred to as A-table), while others require alignment adjustment to be performed with the frame in an inverted state (hereinafter referred to as A-table). , referred to as B table).

For example, in a vehicle where a shim is installed at the joint between the upper arm and the frame, and the shear alignment is adjusted by changing the thickness of the shim, an eccentric cam is installed at the joint between the lower arm and the 7th frame with the frame in its normal condition. For vehicles that require alignment by changing the rotation angle of the eccentric cam, the alignment must be performed with the frame inverted.

However, conventionally, in order to transmit two vehicles (AJjt, B table) with different orientations of the alignment 51 onto the front suspension assembly line, as shown in FIG. 2, and first, move both A and B tables on the main line 1 with the frame reversed 5).Next, set A table on the front axle stand 4 on the main line 1, and place B on the main line 1. 8 to 70 torque assembly process 4' on 2. After that, Car A passes through a reversal step 5 and reaches an alignment step B, where the frame is aligned 61 times with the frame in a normal state. On the other hand, J3

J =':, F76/ is reached, where the predetermined alignment R1:! After that, it is sent onto the main line 1 through a step 5' where it is erected. In other words, after alignment adjustment, both A car and B@ frame are in normal condition and other settings 4:'j
(7) will be sent as a loss.

However, in the case of the above-mentioned two-way feed system, if the production ratio of vehicles (the production ratio of cars A and B) changes, assembly man-hours will be wasted in either the main engine 1 or the main engine 2, and production efficiency will decrease. ■Double investment such as reversal 9
Various problems arose, including increased equipment costs and the need to deploy personnel to the 0-car line, leading to a growing shortage of human resources.

(Objective of the invention) The presently developed ryJ111: AIh solves the problems of the above-mentioned conventional technology,

The purpose of this invention is to provide a vehicle transportation method that can contribute to reducing equipment costs and manpower shortages.

(Ichigo-Sei of the Invention) And, this purpose is to reverse the front axle λ[1 and move the vehicle that is flowing on the main line in an array/inverted state to the frame inverted state or 180 degrees.

(Example) Hereinafter, an example of the present invention will be described based on the attached drawings.

FIG. 2 shows an apparatus system for carrying out the vehicle transport method according to the present invention. In the figure, reference numeral 11 indicates a main line for assembling the front suspension, and vehicle frames j2a and 12b move along this main line 11 at a predetermined speed I.
At W, it flows in the direction of the P arrow. On both sides of the main line 11, there is an alignment adjustment parking machine 16 for a vehicle (vehicle A) for which alignment A must be performed with the frame in its normal state, and an alignment adjustment parking machine 16 for a vehicle (vehicle A) that must undergo alignment adjustment with the frame inverted. Alignment adjustment for car B) 4 steps 1. ; 14 were measured. Moreover, on both sides along the main twin 11, there are first rails 15a, 1
5b is constructed, and the 77, 1 < 7) L'-ru 15
A, 1 sb 2, y, and cq tsR second rails 16a, 16b are mounted on the rails. This t
The rails j 6a, j 6b IJ' of δ2 can be arbitrarily run on the first rails 15a, 15b by driving means (not shown). Reference numeral 17 denotes a conveyor 3 suspended from the vehicle frame 12, which has the function of reversing and conveying the vehicle frame 12;
The 20th rail 16a is driven by a drive means (not shown),
16b It is now possible to walk across the top.

In other words, the transport machine 17 is capable of moving 8nb arbitrarily in the X and Y directions, and transfers the A'J7L%B cars by distributing them to the A car alignment adjustment 4913 and the B car alignment adjustment rock 14, respectively. and alignment a
It plays the role of returning cars A and B, which have completed their alignment, to the main line 11 by running in the direction of the arrows QA, QB.

Hereinafter, a specific method for transmitting a vehicle image will be described with reference to FIGS. 3 and 4. First, on main line 11,
When the vehicle frame 12a, which has been flown in an inverted frame state after completing the front axle assembly process, reaches the above alignment adjustment line, if it is the A table, it will be inverted 180 degrees by the conveyor 17 and then proceed to the vehicle alignment adjustment line. Machine 1
Listed as 0 on 3. As a result, the car's frame will be in a normal state, and the alignment will be adjusted based on that state. on the other hand,
If it is car B, it will not turn over and will be held in place.
In other words, alignment for car B-11 in the reversed state.
It is then subjected to alignment adjustment (No. 31z).

For vehicles that have completed alignment adjustment,
If it is a car A, the frame is already in the normal state, so it is returned to the main line 11 at the 17
180 degrees and return to the main line 11 (Figure J4).

Therefore, the vehicle frame 12b whose alignment has been successfully adjusted becomes the vehicle frame 12b in its normal state, and is sent along the main line 11 toward the equipment A;L.

In this way, according to the main army's method of dropping soil on both sides, it is possible to process it within the main line 11 for both vehicles A and B, and even if the production weight of both vehicles fluctuates, the production efficiency* will not decrease. It becomes possible to perform alignment without
The raw mouth equipment has a reversing function and only requires a few additional lines of 17.
The investment cost for one piece of equipment is now minimal.

FIG. 5 shows another example of the equipment for carrying out the present vehicle]51p transport method. In addition, the same 41" and the same parts as those shown in FIG.
The explanation will be omitted. The "+"!j feature of this first example is that the alignment adjustment machine 15 for car A and the alignment adjustment machine 14 for car B are arranged in series on the main line 11. is the same as the first embodiment, and by driving and using the 64-row Eikyoku 17, the A car is]!
