Furthermore, by moving the pallet outward, the pallet 1 that has been held until then can be released and released.

Next, the operation of this embodiment in a general usage condition will be explained.

FIG. 5 is an explanatory diagram showing an example of the operation of this embodiment.

In FIG. 5, first, before storing the pallets 1, 1...1 in the pallet storage space 21 of the pallet transport device 20, the pallets Il! ! Move the pallet placement section 2 of the feeding device 10 to just below the pallet storage space 21, and move the pallet placement section 2 as shown in the same figure (al) so that the lowest stacked pallet 1 is placed on top of the pallet placement section 2. 1, 1, . . . 1 are stored in the pallet storage space 21.

Next, when supplying one ballen l-1, in the same figure (b
), when the pallet 1 is held by the pallet holding mechanism 30 and lifted upward to the second bar 1 from the bottom among the pallets 1, 1... With only one pallet loaded, place it on the other pallet 1.1.
...1 is held far above.

Note that the shaded pallet 1 in FIG. 2B indicates that it is held by the pallet holding mechanism 30.

Hereinafter, among the pallets 1 in the pallet storage space 21 in FIG.
Similarly, it is assumed that among the pallets 1 in the pallet storage space 51, all of the pallets 1 with diagonal lines are held by the holding mechanism 60.

Next, move the pallet placement unit 2 to a position (in the example of FIG.
Figure 5 (C
) and stop at -.

Therefore, parts and the like are dropped or placed on a predetermined location within the pallet 1 to be accommodated. This storage of parts is normally continued with the pallet 1 stopped until all the outlets of the partition frames provided in the pallet 1 are filled with parts.

Next, as shown in the same figure (d), the pallet mounting part 2 is
It is moved directly below the pallet storage space 51 of the pallet stacking device 50. After the pallet 1 that has been carried is held by the pallet holding mechanism 60 and lifted upward, the pallet mounting section 2 is again moved to just below the pallet storage space 21, and the operations shown in the figure (al) are repeated.

If the loading section 2 on which the pallet 1 with parts storage has been placed comes below the pallet housing space 51, if a pallet 1゜1...1 is already housed in the pallet housing space 51. , as shown in FIG. 1(e), the lowest pallet 1 among the pallets 1, 1, . The mounting section 2 can be inserted.

Then, the pallets 1, 1, which were held by the pallet holding mechanism 60 inside the pallet storage space 51,
...By releasing the hold on the lowest pallet 1, the pallet that was already stored on the pallet 1 that was carried last will be placed on the pallet mounting section 2 as shown in the same figure (fl). ll, 1...1 are stacked. In this state, the lowest pallet (the last pallet brought in) 1 is held and lifted by the barrel l/holding mechanism 60, and as shown in the same figure (gl), All of the pallets 1.1...1 are separated from the pallet mounting section 2 above.

Thereafter, the pallet mounting section 2 is moved and positioned directly below the pallet storage space 21 of the pallet transport device 20. By repeating such operations, the pallets 1 are supplied one after another by the pallet conveying device 20, transported by the pallet conveying device 10, and stacked by the pallet stacking device 50.
Since the parts are stacked by the pallet stacking apparatus, the pallets containing the parts in an orderly manner can be taken out from the pallet stacking device in a convenient state for storage or packaging.

All of these operations are controlled by an electronic control device (not shown) and are automatically performed.

Note that the pallet conveying device 20 and the pallet stacking device 50
Since they have the same mechanism and the same functions, they can be used interchangeably.

Next, as a specific usage example of the present embodiment, a case where the present embodiment is incorporated into an automated system using two winding machines and a winding finishing device will be briefly described.

FIG. 6 is a plan layout diagram showing an example in which this embodiment is installed and used adjacent to a winding finishing device.

In FIG. 6, a coil hobbin conveying device 80 is for supplying a coil hobbin to a winding machine (not shown), and holds the coil bobbin in fingers 81, and a threaded portion 83 of a hole screw is attached along a linear kite rail 84. It can be moved horizontally by being driven.

Further, the coil hobbin conveying device 90 performs the finishing process in cooperation with each device for the winding finishing process, and the
Hold the coil hobbin at 1゛ and set the linear kite rail 94.
By driving the threaded portion 93 of the hole screw along the horizontal axis, the threaded portion 93 of the hole screw can be moved horizontally.

In order to perform a consistent process of finishing one winding using these devices, the finger 81 receives the coil bobbin from the parts tweeter 82, carries it in front of a winding machine (not shown), delivers it to the winding machine, and finishes the winding and terminal. Nokarage and other ceremonies are held.

The coil bobbin that has finished winding is transferred to the finger 81 again, and the finger 81 moves to come in front of the finger 91. Here, the wound coil bobbin is connected to the finger 81.
The coil bobbin received by the finger 91 is moved horizontally with the received coil bobbin facing downward, and the soldering process is stopped above the solder bath 85a of the device 85 to solder the terminal. Next, it stops above the cleaning tank 86a of the cleaning device 86, and the soldering area is cleaned. Next, dryer 8
It stops above the dry air outlet 87a of No. 7 and performs drying after cleaning. Next, the sensor section 88a of the defective product sorting device 88
Stop above the winding and check the winding continuity. Next, the device stops above the defective product removal device 89 to release only the defective products into the defective product storage box 89a, and finally the pallet is placed at the position of the finger 91 shown by the two-dot chain line in the manner explained in FIG. A storage unit 2 receives the completed coil bobbins from a pallet conveying device 20, and drops the completed coil bobbin products at a predetermined location on the carried barren 1 to arrange and accommodate them.

These operations were repeated several times, and each time, the relative positional relationship between the finger 91 and the pallet 1 on the loading section for the baren 1 was shifted, and all of the partitioned discharge ports provided on the pallet were filled with coil hobbins. Thereafter, the pallets 1 are stacked and neatly stored in the pallet storage space 51 of the pallet stacking device 50.

As described above, 50 in FIG. 6 can be used as a pallet conveying device, and 20 can also be made to function as a pallet stacking device.

Further, each device for the winding finishing process of the two winding devices and the pallet feeding, conveying, and stacking device of this embodiment can be controlled synchronously by the same control device.

Moreover, the pallet holding mechanism 30. The structure of the pallet is not limited to this embodiment, and for example, the pallet may be held by supporting the protruding portion of the pallet from below.

(Effects of the Invention) As explained in detail above, the pallet supply/conveyance/stacking device according to the present invention has spaces at both ends of the pallet conveyance device in which pallets can be stacked and accommodated, and pallets can be stacked in one pallet storage space. The lowest pallet is moved horizontally by a pallet transport device, and after completing processes such as arranging parts on the pallet, it is transported to the lower part of the other pallet storage space and the pallets are stacked. This has the effect of being able to be incorporated into various automated processing equipment systems to efficiently supply, transport, and stack pallets in an extremely small space without requiring manual labor or special equipment.
