Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear suspension supply device applied to an automobile assembly line, and more particularly to a rear suspension supply device.
The present invention relates to a rear suspension supply device suitable for a separate type rear suspension in which left and right drums are separated.

[0002]

2. Description of the Related Art In recent automobile assembly lines, a method of mixed production of a plurality of vehicle types tends to be actively adopted. As such mixed flow production progresses, it may be necessary to assemble vehicles of completely different suspension types on the same line.

Now, as shown in FIG. 4, a left and right drums 1 are integrally connected by an axle beam 2 in a 3-link type suspension which has been widely adopted as a rear suspension of a front-wheel drive vehicle. As for such suspensions, those assembled at another factory are placed on a supply pallet, carried into an automobile assembly line, gripped one by one by a rear suspension supply device, and supplied to a receiver on a toe conveyor. It is conveyed to a predetermined assembly position by a conveyor.

FIG. 5 shows a gripping mechanism for gripping an integrated rear suspension in which left and right drums are integrally connected and supplying it from a supply pallet to a toe conveyor, like the above-mentioned 3-link type suspension. , A carrier 3 provided with a longitudinal and vertical movement mechanism (not shown)
In addition, a pair of left and right holders 5 that slide left and right by the operation of the cylinder 4 to open and close are attached. In such a gripping mechanism, for example, when pressure fluid is supplied to the cylinder 4, the left and right drums 1 can be gripped while being pressed in the direction in which the holder 5 closes inward in the axial direction.

[0005]

By the way, in the rear suspension of a front wheel drive vehicle, in addition to the integral type such as the above-mentioned 3-link type suspension, for example, as shown in FIG. 3, the left and right drums 1 are separated. A separate type such as the multi-link type suspension has been developed and put into practical use. Such a separate-type suspension cannot use the above-mentioned conventional gripping mechanism because the left and right drums are not connected. Therefore, in the conventional device, different types such as an integrated type and a separate type suspension cannot be used. It was difficult to produce a mixed flow model of a vehicle that adopted the rear suspension. In FIG. 3, 6 is a lower arm and 7 is a trailing arm.

Therefore, an object of the present invention is to provide a rear suspension supply device which can take out a separate type rear suspension from a supply pallet and supply it to a receiver on a toe conveyor.

[0007]

SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned problems, and a separate type rear suspension having left and right drums separated is taken out from a supply pallet and supplied to a predetermined position on a toe conveyor. In the rear suspension supply device, a carrier having a longitudinal and vertical movement mechanism is provided with two sets of gripping mechanisms for independently gripping the left and right sides of the rear suspension, respectively. Is.

[0008]

According to the above-mentioned means, since the gripping mechanism dedicated to each of the separated left and right drums is provided, the left and right drums are individually gripped and taken out from the supply pallet, and the predetermined drums on the toe conveyor are picked up. It becomes possible to feed to the position at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the rear suspension supply device according to the present invention will be described with reference to FIGS.

In the front view shown in FIG. 1, the multi-link suspension having a structure in which the left and right drums 1 are separated is
The work 11 in which the lower arm 6 and the trailing arm 7 are assembled to the drum 1 constitutes one set on the left and right and is placed on the supply pallet 12. The rear suspension supply device that takes out the work 11 from the supply pallet 12 and supplies the work 11 onto a toe conveyor (not shown) includes a carrier 13 having a moving mechanism in the front-rear direction and a vertical direction, and two sets of gripping mechanisms 14 provided in the carrier 13. The gripping mechanism 14 comprises a pair of holders 15 and an opening / closing cylinder 16, respectively.

In the carrier 13, a vertical slide frame 21 is movable up and down with respect to a base frame 20 connected to a front-rear moving mechanism including a drive motor 17 (see FIG. 2), a guide rail 18 and wheels 19. Further, the rotary frame 22 is rotatably supported by the vertical slide frame 21, and the gripping mechanism 14 provided on the rotary frame 22 also rotates integrally.

The vertical movement mechanism of the vertical slide frame 21 includes a drive motor 23 installed on the base frame 20, drive chains 24 and 25, a guide rail 20a provided on the base frame 20, and a slider 26 attached to the vertical slide frame 21 side. Etc. The drive chains 24 and 25 connect the drive motor 23 and the upper and lower slide frames 21, and the upper and lower slide frames 21 are connected to the base frame 20 according to the rotation direction of the drive motor 23.
Move up and down.

The rotating mechanism of the rotary frame 22 uses a cylinder 27 fixed to the upper and lower slide frames 21 as a drive source, and the rotary frame 22 connected to the tip of the piston rod 27a is expanded and contracted according to the expansion and contraction of the piston rod 27a. , Is configured to rotate about the rotation shaft 28.

The operation of the above-mentioned rear suspension supply device will be described below based on the work procedure.

Since the work 11 on the supply pallet 12 is first taken out, the carrier 13 moves in the front-rear direction and stops on the target work 11. Thereafter, the vertical slide frame 21 is lowered together with the rotary frame 22 and the gripping mechanism 14 to the position shown by the imaginary line, and the opening / closing cylinder 16 is operated to close the holder 15. As a result, the left and right workpieces 11 are held between the holders by the respective drum portions, and are lifted from the supply pallet 12 as the vertical slide frame 21 is lifted.

The work 11 taken out in this way is conveyed onto the receiving member of the toe conveyor 29 (see FIG. 2) by the movement of the carrier 13 in the front-rear direction.

Then, at an appropriate position during this conveyance, the cylinder 27 operates to work together with the work 11 and the rotary frame 2.
2 is rotated 90 degrees and the direction of the trailing arm 7 taken out downward is corrected to a substantially horizontal body assembly state.

The work 11 conveyed onto the receiving member of the toe conveyor 29 descends together with the vertical slide frame 21, and then the holder 15 opened by the operation of the opening / closing cylinder 16.
To be supplied onto the receiver. In this way, the carrier 13 to which the left and right one set of works 11 is supplied moves up to the position where the next work is taken out by raising the vertical slide frame 21. On the other hand, the toe conveyor 29 which receives the supply of the work 11 conveys the work 11 to the rear suspension assembly position of the automobile assembly line.

Now, the rear suspension supply device in the case where the separate type rear suspension described above and the integrated rear suspension shown in the conventional example are produced in a mixed flow on the same line, may be constructed, for example, as shown in the side view of FIG. Good. That is, the carrier 32 for the separate rear suspension and the carrier 33 for the integrated rear suspension are attached to the common base frame 31 that moves in the front-rear direction (the arrow 30 in the figure) by the drive motor 17, and the work is supplied. Then, either one is selected and used.

Carrier 3 for separate rear suspension
Similarly to the above-described embodiment, the drive motor 2 moves up and down by the drive motor 23 and rotates by the cylinder 27. The carrier 32 has a pair of left and right workpieces 11
Corresponding to the above, two sets of gripping mechanisms 14 are provided.

On the other hand, the carrier 33 for the integrated rear suspension is moved vertically by the drive motor 34 and is equipped with a rotation mechanism (not shown). The work is held by a pair of left and right holders as in the conventional example. Is configured to.

With this structure, the amount of movement of the common base frame 31 is adjusted according to the type of the rear suspension to be supplied, and when the separate rear suspension is supplied, the carrier 32 is stopped on the target work. When supplying the integrated rear suspension, the carrier 33 is stopped on the target work so that any type of work can be taken out from the supply pallet 12 and the toe conveyor 29.
Can be supplied to.

[0023]

According to the present invention described above, even if a separate type having a structure in which the left and right drums are separated, such as a multi-link type rear suspension, both types can be obtained by modifying a conventional integral type feeding device. Therefore, it is possible to provide a device that can cope with the above, and it is very effective in promoting the mixed flow production line and automating the rear suspension supply.
