Further, a lever receiver 231 is attached to an upper portion of the swivel base 23. In addition, the gutter 5 surrounds the swivel table 23.
3 is fixed.

An oil pan 5 is attached to the lower side of the work mounting device 21.
1 and an arc-shaped oil pan 52 arranged below the oil pan 51, and the discharge unit 4 is attached to a side surface of the oil pan 52. The operating lever 43 is operated by the lever receiver 231 when the work mounting device 21 is lowered to the lowest stage.

Reference numeral 7 denotes an electric turntable type setup station.

Next, a description will be given of a delivery operation of the work W using the above-described work handling device and an operation of discharging the cutting oil stored in the oil pan 5.

The unprocessed work W set on the pallet at the pallet receiving table of the setup station 7 is
It is mounted on the pallet support of the work mounting device 21 by the fork device 211. The unprocessed work W mounted on the pallet support of the work mounting device 21 is
The work W is moved to a position facing the storage frontage 11 where the work W is not stored by the lifting and lowering of the work 2 and the turning of the swivel table 23,
It is stored in the pallet support of the storage frontage 11 by the fork device 211. When setting up another work W, the storage frontage 11 in which the empty pallet is stored is used.
The empty work pallet is taken out from the pallet support of the setup station 7 and an unprocessed work W is set. The unprocessed work W set on the pallet is stored in the pallet support of the storage frontage 11 in the same manner. .

When the manual setup is completed and the unmanned operation is performed, first, the pallet receiving table of the work mounting device 21 is not moved by the lifting and lowering of the lifting and lowering table 222 and the turning of the rotating table 23. It is moved to a position facing a predetermined storage frontage 11 of the storage shelf 1 in which the work W for processing is stored,
The unprocessed work W stored in the storage frontage 11 is mounted on the pallet support of the work mounting device 21 by the fork device 211. The unprocessed work W mounted on the pallet support of the work mounting device 21 is moved to a position opposed to the intermediate roller base 6 attached to the machine tool 3 by raising and lowering the elevating table 222 and turning the swivel table 23. Is transferred to the intermediate roller base 6 by the fork device 211 and supplied to the machine tool 3.

When the unprocessed work W is supplied to the machine tool 3, the pallet support of the work mounting device 21 is next supplied to the machine tool 3 by raising and lowering the elevating table 222 and turning the swivel table 23. The unprocessed work W stored in the storage frontage 11 is moved to a position facing the storage frontage 11 of the storage shelf 1 in which the unprocessed work W to be stored is stored by the fork device 211. Mounted on a pallet support. When the unprocessed work W is mounted on the pallet support of the work mounting device 21, the side of the pallet support on which nothing is mounted is attached to the machine tool 3 by raising and lowering the lift 222 and turning the swivel 23. The workpiece W is moved to a position facing the intermediate roller base 6 and waits for the processing of the workpiece W supplied to the machine tool 3 to be completed. When the processing of the work W is completed, the processed work W is transferred to the work mounting
Is mounted on the pallet support on the side where nothing is mounted. When the processed work W is mounted on the pallet support of the work mounting device 21, the swivel 23 rotates 180 °, and the unprocessed work W mounted on the pallet support of the work mounting device 21 is processed. It is moved to a position facing the intermediate roller base 6 attached to the machine 3, transferred to the intermediate roller base 6 by the fork device 211, and supplied to the machine tool 3. The cutting oil falling from the processed work W mounted on the pallet support of the work mounting device 21 is stored in the oil pan 52 via the oil pan 51,
The cutting oil stored in the oil pan 52 is discharged when the work mounting device 21 descends to the lowest stage as described later.

The processed work W mounted on the pallet receiving table of the work mounting device 21 is moved up and down by the elevating table 222 and swiveling of the swivel table 23 to store the frontage 11 of the storage shelf 1 in which the work W is not stored. And is stored in the pallet support of the storage frontage 11 by the fork device 211. Further, when there is an unprocessed work W to be processed by the machine tool 3, the work mounting device 2
The storage frontage 11 of the storage shelf 1 in which the unprocessed work W to be supplied to the machine tool 3 is stored in one pallet receiving stand.
The unprocessed work W stored in the storage frontage 11 is mounted on the pallet support of the work mounting device 21 by the fork device 211, and the delivery of the work W is repeated in the same manner. It should be noted that the work mounting device 21 descends to the lowest stage because the work mounting device 2
One pallet receiving tray is the lowermost storage frontage 11 of the storage shelf 1
, The work W is placed at the bottom of the storage frontage 1
When it is stored in the pallet holder 1 or when the work W
Is taken out from the lowermost storage frontage 11, the cutting oil stored in the oil pan 52 is discharged. That is, the hose 41 and the hose receiver 46 of the discharging means 4 are normally
As shown in FIG. 7, the cutting oil accumulated in the oil pan 52 is not discharged through the hose receiver 46 because the cutting oil is directed upward by the spring 42. As shown in FIG. 3, the operating lever 43 hits the lever receiver 231 and the operating lever 43
Rotates around the pin 47 and the hose 41 and the hose receiver 46 are directed downward, so that the cutting oil stored in the oil pan 52 is discharged to the gutter 53 through the through holes of the hose 41 and the hose receiver 46.

The processed work W stored in the pallet support of the storage frontage 11 of the storage shelf 1 is mounted on the pallet support of the work mounting device 21 by the fork device 211, and the lifting and lowering and moving of the lifting and lowering table 222 is performed. The table 23 is moved to a position facing the pallet receiving table of the setup station 7 by the rotation of the table 23, is transferred to the pallet receiving table of the setup station 7 by the fork device 211, and is manually removed from the pallet.

Although the embodiments of the work handling apparatus of the present invention have been described above, the present invention is not limited to these embodiments.
For example, a plurality of different types of machine tools 3 may be provided.

Further, the storage frontage 11 of the storage shelf 1 may be arranged linearly, and the work transfer device 2 may be mounted on a traveling body running along the storage frontage 11 of the storage shelf 1.

[0027]

Since the work handling apparatus of the present invention is constructed as described above, the cutting oil falling from the work is collected in the receiving tray to prevent the surroundings from being contaminated and to be stored in the receiving tray without stopping the operation. The cutting oil can be discharged, and the time for discharging the cutting oil can be eliminated, and the worker does not need to approach the work handling device to ensure safety. Further, since the cutting oil is discharged when the work mounting device descends to the lowermost stage, the falling distance of the discharged cutting oil can be shortened, and the rebound of the cutting oil can be reduced.
