A transport conveyer that can be entered, a panel erecting mechanism connected to the panel convey direction of the conveyer and erecting a panel sent from the conveyer, and a conveyer and panel erecting in a direction orthogonal to the arrangement direction of the panel storage. It is characterized by having a structure provided with a conveyor moving mechanism for moving the mechanism in and out of the panel storage and the panel gripping elevating clamp by reciprocating the mechanism as a unit and moving the conveyor in and out. This is a means for solving the above-mentioned conventional problem.

[0011]

In the panel transfer device according to the present invention,
When the lifting / lowering clamp for holding the panel clamps one panel from the panel storage designated by the production instruction and moves above the panel storage arranged in series with the panel transport device, the transport conveyor is operated by the operation of the conveyor moving mechanism. Moves to the panel storage side together with the panel erecting mechanism, and the transport conveyor enters between the panel storage and the panel holding up / down clamp.

Next, when the panel gripping lifting / lowering clamp is lowered to release the panel and then rise again, the panel is sent to the panel upright mechanism by the operation of the transport conveyor, and subsequently the panel is upset by the operation of the panel upright mechanism. Stand up.

During this time, the conveyor and the panel erecting mechanism move integrally to the opposite side of the panel storage due to the operation of the conveyor moving mechanism, so that the conveyor is retracted from between the panel storage and the panel holding up / down clamp. The panel reaches the next step in the upright state.

That is, since it is not necessary to arrange the panel transport device in parallel with the panel storage, the panel storage is increased by the amount of the panel transport device.

Further, even if the number of the panel transport devices is increased in accordance with the number of the panel storages, the distance in the arrangement direction of the panel storages is not increased, so that the space can be effectively used.

Further, since the panel is in the upright state during the transport of the panel, the transport time until the next step is short.

First, the lifting / lowering clamp 5b for gripping the panel of the overhead loader 5 clamps one front floor panel F from the panel storage (eg, the panel storage 1) designated by the production instruction. As shown, when moving above the panel storage 3 disposed in series with the above-described panel transport device 10,
Due to the rod pushing operation of the conveyor moving cylinder 41 in the conveyor moving mechanism 40, the belt conveyor 20 moves to the panel storage 3 side together with the panel upright mechanism 30, and as shown by a solid line in FIGS. The belt conveyor 20 enters between the storage unit 3b and the panel holding elevating clamp 5b. At this time, since the proximity switch 15 detects the approach of the frame 12, the belt conveyor 20 stops at a predetermined position.

Next, when the panel gripping lifting / lowering clamp 5b is lowered to release the front floor panel F and then rise again, the belt conveyor 20 is operated to send the front floor panel F to the main body 31 of the panel standing mechanism 30, and The floor panel F is gripped by clamps 34, 35 driven by cylinders 32, 33.

Subsequently, the erecting cylinder 37 of the panel erecting mechanism 30 performs a rod pushing operation, whereby the front floor panel F held by the clamps 34 and 35 on the main body 31 erects.

At the same time, since the conveyor moving cylinder 41 of the conveyor moving mechanism 40 operates to retract the rod, the belt conveyor 20 and the panel upright mechanism 30 move integrally to the opposite side of the panel storage 3, and the belt conveyor moves. 20 withdraws from between the panel storage 3 and the panel-holding elevating clamp 5b, as shown in FIGS.
As shown by an imaginary line, the next step is reached with the front floor panel F standing upright. Also at this time, since the proximity switch 16 detects the approach of the frame 12, the belt conveyor 20 stops at a predetermined position.

Then, the clamp 3 of the panel erecting mechanism 30
After releasing the gripping by the front and rear panels 4 and 35 and transferring the front floor panel F to the next step, the lifting / lowering clamp 5b for gripping the panel of the overhead loader 5 moves the front floor panel F from the panel storage designated by the next production instruction.
Is clamped by one sheet, and in accordance with moving above the panel storage 3 arranged in series with the panel transfer device 10, the rod moving operation of the conveyor moving cylinder 41 of the conveyor moving mechanism 40 again causes the panel storage 3 to move. The belt conveyor 20 is inserted between the storage unit 3b and the lifting / lowering clamp 5b for holding the panel, and the above operation is repeated thereafter.

The panel transporting device 10 in series with the panel storage 2 (the upper panel storage in FIG. 2) is also provided.
An operation similar to the operation described above is performed.

Therefore, in the panel transport apparatus 10, the front floor panel F can be transported from the panel storages 1, 2, 3, and 4 without being arranged in parallel with the panel storages 1, 2, 3, and 4. , A panel storage can be added to a space required for installing a panel transport device (belt conveyor).

Further, even if the panel transport device 10 is added, the distance in the arrangement direction of the panel storages 1, 2, 3, and 4 does not change, so that the space can be used effectively.

Further, in the panel transfer apparatus 10, the front floor panel F is in an upright state during the transfer of the front floor panel F, so that the operation of erecting the front floor panel F before the next process can be omitted. As a result, the transport time is short.

In the above-described embodiment, the case where the panel transfer apparatus according to the present invention is applied to the floor main assembly line of an automobile has been described. However, the present invention is not limited to this. In addition to being applicable to the line, the detailed configuration is not limited to the above-described embodiment.

[0040]

As described above, the panel transfer device according to the present invention has the above-mentioned structure, and therefore can be arranged in series with the panel storage, and the panel transfer device which has been required conventionally. Panel storage can be added to the space for installing the panel storage device, and even if a panel transport device is added, the distance in the direction in which the panel storages are arranged does not increase, so that the space can be used effectively. In addition, since the panel can be erected at the same time as the panel is transported, an extremely excellent effect that the transport time of the panel until the next step can be shortened is brought about.
