Description

[Detailed description of the invention] Industrial applications The present invention can be applied to automobile production lines.

The present invention relates to a device for lifting and tilting a transported object, which is used to lift and then tilt a vehicle body transported by a trolley-type transport device.

In a conventional automobile manufacturing line, there is a step in which a vehicle body supported by a suspended conveyance device is put into an electrodeposition bath, and after being taken out from the electrodeposition bath, it is transferred to a trolley-type conveyance device and conveyed to a drying oven. In this case the car body.

The electrodeposition solution taken out from the electrodeposition tank is drained.

In this case, conventionally, the liquid was drained by tilting the hanger of the hanging conveyance device and tilting the vehicle body integrally.

Problems to be Solved by the Invention According to the above-mentioned conventional system, if the hanger is tilted too much, there is a risk that the vehicle body will fall off, and therefore, since the hanger can only be tilted small, it is not possible to drain the liquid sufficiently. Furthermore, when the vehicle body is displaced from the hanger, the supported portion of the vehicle body comes into sliding contact, causing wear and tear and the paint peeling off.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device for lifting and tilting an object to be transported, which can tilt a vehicle body significantly without causing wear and tear or falling off.

Next, the operation of lifting and then tilting the vehicle body 1 in the above embodiment will be explained.

The trolley 6 receives the driving force of the traveling drive device 7 and moves along the transport path 5.
and both lifting devices 10A.

The vehicle is stopped with the vehicle body 1 positioned in the L direction of 10B.

At this time, both lifting devices! In OA and IOB, cylinder fittings @ 16A and 16B move to contract, and both receivers 23A and 23
B is moving downward. As a result, both horizontal receiving portions 26A.

The sealing part (receiving surface) la of the vehicle body 1 faces 26B from the rear side, and the wheel mounting part 1b faces the inclined receiving part 36.
is facing from the t direction. In this state, the cylinder device 16A
, 16B are extended and the one-car receivers 23A, 23B are raised, the horizontal receivers 26A, 26B are moved to the seal portion 1.
a from below, thereby lifting the vehicle body 1 on the truck 6. At that time, if the cylinder devices 16A and 16B extend by the same amount, the vehicle body 1 can be lifted horizontally as shown by the imaginary line A in FIG. Transfer can be performed using a fork. When a difference is made in the amount of extension of the cylinder devices 16A and 16B mentioned above.

In other words, the external view of one holder 23A is compared to the other holder 2.
By making it larger than the L riser of 3B, the car body l is tilted so that the 23A side of both Iζ is on the upper side, as shown by the temporary phase line B in FIG. At this time of inclination, both receivers 23A,
23B, as shown by the imaginary lines in FIGS. 1, 3, and 6,
The left and right axes 29A and 2 are arranged so that the horizontal receiving parts 26A and 26B are along the seal part 1a of the vehicle body 1, respectively.
9B and thus the horizontal receiving part 26A of the sealing part 1a.

All the portions corresponding to 26B come into contact with each other, and the receiving area is varied. Further, the force that tends to move the tilted vehicle body 1 toward the lower side of the tilt is blocked by the inclination receiving portion 36 of the other receiver 23B not receiving the wheel installation portion 1b of the vehicle body 1.

Also, when the vehicle body 1 is tilted, both horizontal receiving portions 26A.

26B changes, as shown by the imaginary line C in FIG. 6 and the imaginary line iζ in FIG. 6.

One receiver 23A resists the spring 2o and the other receiver 2
3B is absorbed by moving away from it, so that no sliding contact occurs between one horizontal receiving portion 26A and the seal portion 1a.

Due to the above-mentioned inclination, for example, the liquid that has been carried out by the vehicle body 1 can be drained, and at that time, the above-mentioned inclination receiving part 36 receives the liquid.

Tilting can be done safely even at large angles. After that,
By performing a reverse operation to that described above, the car body 1 is brought into a horizontal state, and is returned to the trolley 6 to be transported to the next process.

By returning the vehicle body 1 to a horizontal state, the tilted receivers 23A and 23B automatically become horizontal around the left and right axes 29A and 29B, and one of the receivers 23A is also aligned with the spring 2.
It moves to its original position with the help of an elastic force of 0.

Note that when both receivers 23A and 23B are not loaded, the horizontal receivers 26A and 26B are automatically swung by weight biasing by the blocks 30A and 30B so that the horizontal receivers 26A and 26B are always in a horizontal state. Seal part 1a by lifting
The contact can be made stably and accurately.

Effects of the Invention and According to the present invention having the structure described above, after the object being conveyed by the conveying device is stopped between the upper parts of both lifting devices, the lifting drive devices of both lifting devices are operated to move both receivers. By raising the conveyor belt, the conveyed object can be lifted via the horizontal receiving portions of both receivers. At that time, by making the L length of one receiver larger than the amount of rise of the other receiver, the transported object can be tilted so that one receiver side is in a standing position, which allows the liquid to be You can do things like cut. When tilted like this, both receivers can automatically swing their horizontal receivers around their respective left and right axes along the receiving surface of the transported object, thus reducing the receiving area. (the contact area of the receiving surface) can be maintained. Furthermore, the force that tends to cause the conveyed object to move toward the lower side of the slope can be stopped by the inclined receiving part of the other receiver receiving the conveyed object, so that the conveyed object can be moved larger without falling off. It can be tilted and drained easily. In addition, changes in the distance between the two horizontal receiving parts due to the inclination of the transported object can be absorbed by moving one of the receiving parts in the front-back direction, and the receiving parts of the vehicle body no longer come into sliding contact, causing paint damage due to wear and tear. It can prevent baldness from rubbing.
