にくいという大きな不便がある。[Prior art and its problems] It is known that a pallet exchange device for a machine tool is equipped with a processing station, a setup station, an intermediate station, and an idle station, but this conventional device has four stations for exchanging pallets. Because of this, the equipment becomes large-scale, and there are problems in that the processing station has to stop for a long time to change pallets, and it is difficult for the operator to approach the front side of the processing station, which is a major inconvenience. Also, a three-station pallet exchange device is described in foreign literature (catalog of Gray Company, USA);
This conventional equipment has a setup station and an intermediate station placed on both sides in front of the processing station, and because the distance between the three stations is long, they do not interfere when conveying the pallets, but it has the major drawback of increasing the floor space. Since the intermediate station and the setup station are arranged symmetrically in front of the processing station, there is a major inconvenience in that it is difficult for workers to approach them.

A saddle 3 moves left and right on the guide surface of a cross rail 2 that is set up on a column bed (not shown) on the floor and mounted on the front, and a turret 4 is mounted on the front of the saddle.
A cutter rod 5 passes through the cutter rod, and a cutting tool holder is attached to the lower end of the cutter rod. A processing table 6 is mounted on a table bed (not shown) and rotates at high speed.
P1 is sent in and clamped to process the workpiece (not shown) attached to the first pallet. Here, the work performed by the processing table 6 is referred to as a processing station S. 10 is a first table which is placed on a table bed (not shown) and stops or slowly rotates;
A new workpiece is attached to a pallet (not shown) placed on the upper delivery rail 11, or a processed workpiece is removed from this pallet. Here, the working position of the first table 10 is set to the processing station S.
Bring it closer to the front and lean it slightly to the left. Reference numeral 12 denotes a second table, which is placed on the table bed B, stops or slowly rotates, and places the second pallet P2 with a new workpiece attached on the conveyance rail 13 on the upper surface and waits. Here, the working position of the second table 12 is referred to as a second station S2 , and this station S2 is approached to the left midway between the processing station S and the first station S1 . In this embodiment, the processing station S and the first station
Since a wide space X is created on the right side of S1 , the worker can approach the processing station S and freely inspect the processing status of the workpiece.
