[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer system having a temporary storage function capable of temporarily storing an object to be transferred in a transfer device during transfer.

[0002]

2. Description of the Related Art Conventionally, as a transfer system of this type, FIG.
There is one configured as shown in. This transfer system includes a first transfer device 31 and a second transfer device 32 arranged in the same transfer plane as the first transfer device 31.
It is composed of a storage device 33 such as a rack arranged between the two transport devices 31 and 32. The storage device 33 is
The storage place of the transported object is configured in a plurality of stages, and is vertically moved by a vertical movement drive device 34 configured by a uniaxial unit or the like.

In this transfer system, a transfer target object 35, such as an alumina substrate, which has been transferred by the first transfer device 31 and has undergone thick film printing such as a wiring pattern in the previous step, is stored in the storage device 33 in a predetermined manner. It is sent to a tier and temporarily stored in that storage tier. When the storage stage is fully loaded with the transported objects, the storage device 33 is moved up and down by the vertical movement drive device 34, and the transported objects are stored in another storage stage.

The objects to be transported temporarily stored in the storage device 33 are removed from each of the storage steps by a pusher or the like after the completion of a predetermined work such as an appearance inspection by a sampling method. The second transfer device 3 is pushed out to the outside.
It is placed on the sheet 2 and conveyed to the next step such as the firing step.

[0005]

In the transfer system having the temporary storage function configured as described above, the first transfer device 31 and the second transfer device 32 are arranged in the same transfer plane. Therefore, the operation of sending the transported object to the storage device 33 and the operation of taking out the transported object from the storage device 33 cannot be performed at the same time, which causes a problem that a time loss occurs in the transport operation of the transported object. It was

Now, assuming that the first transport device 31 and the second transport device 32 are arranged on different transport planes by changing their vertical positions, and the number of storage stages of the storage device 33 is increased, A device 3 for temporarily storing the transported object.
Although it is possible to simultaneously perform the operation of sending the transferred object to the storage device 3 and the operation of taking out the transferred object from the storage device 33,
In the case of No. 3, since the whole is simply moved up and down, there is a limit to the improvement of the above problems.

Therefore, it is an object of the present invention to provide a transfer system having a temporary storage function that can further reduce the time loss of the transfer operation of the transferred object.

[0008]

The second transport device 2 side end is configured to face the end of the second transport device 2.

In the transport system of the present embodiment constructed as described above, when the third transport device 3 is in the position shown in FIG.
The transported object 16 transported by the third transport device 3
It is fed onto the wire belt 15 of the lower stage transport device 3b. At this time, for example, the first conveyed object 16 sent to the lower conveying device 3b is extracted by a robot or the like, and a predetermined work such as an appearance inspection is performed on the extracted conveyed object 16. This work is completed by the time the lower transfer device 3b is fully distributed with the transferred objects 16.

As described above, when the object 16 to be conveyed is fed to the lower conveying device 3b, the object 16 to be conveyed on the wire belt 12 of the upper conveying device 3a has already been subjected to predetermined work such as visual inspection. When the belt 12 is driven, the belt 12 is taken out from the upper conveying device 3a and fed onto the wire belt 9 of the second conveying device 2.

When the lower transfer device 3b is fully distributed with the objects 16 to be transferred (however, at this time, the upper transfer device 3b is
The removal of the transported object 16 of a has also been completed. ), It is detected and the both ends of the third conveying device 3 are inverted in the vertical direction to be in the state shown in FIG. At this time, the object 16 to be conveyed that has been conveyed by the wire belt 6 of the first conveying device 1 is fed onto the wire belt 12 of the upper conveying device 3 a of the third conveying device 3. At this time, similarly to the case of the lower-stage transfer device 3b, the transferred object 1 extracted
Perform predetermined work such as appearance inspection on 6. This work is completed by the time the upper transfer device 3a is fully distributed with the objects to be transferred 16.

As described above, when the object 16 to be conveyed is fed to the upper conveying device 3a, the object 16 to be conveyed on the wire belt 15 of the lower conveying device 3b has already been subjected to a predetermined work such as visual inspection. When the belt 15 is driven, the belt 15 is taken out from the lower conveying device 3b and fed onto the wire belt 9 of the second conveying device 2.

When the upper transfer device 3a is fully distributed with the transferred object (at this time, the removal of the transferred object from the lower transfer device 3b is finished), it is detected and the third transfer device 3 is detected. Figure 1
Return to the state of.

That is, both ends of the third transfer device 3 are repeatedly inverted up and down like a seesaw, so that the upper transfer device 3a and the lower transfer device 3b are alternately stored in the conventional example shown in FIG. In addition to having a temporary storage function similar to the storage stage of the device 33, the operation of sending the transported object 16 to the third transportation device 3 and the operation of taking out the transported object 16 from the third transportation device 3 are substantially continuous. Therefore, the time loss of the transport operation can be reduced.

When it is determined that the object 16 is defective by the visual inspection or the like performed on the object 16, the object 16 is conveyed for each quantity unit sent to the upper conveying device 3a or the lower conveying device 3b. A bad mark is attached to and the transported object 16 with the bad mark is discarded or corrected in a later process.

FIG. 3, FIG. 4 and FIG. 5 show a more specific structure of the transfer system having the temporary storage function of the above embodiment. 3 and 5 are side views of the transfer system, and FIG. 4 is an enlarged top view of the first transfer device 1.
