状態で露出する時間は極めて短かい。<Prior art> Recently, large tables such as large portal machine tools, such as vertical boring machines, plano milling machines, or large horizontal boring machines, are used to feed cutting only in the longitudinal (back and forth) direction on the bed. In machine tools as well, labor saving,
For unmanned work or even multiple-machine line work, workpieces are attached to pallets in advance at a setup station, transported and automatically placed on the machine table, and the pallets removed after processing are transferred to the next process machine. The application of a production method that automatically attaches and detaches parts by transferring them to other parts is expanding. In small machining centers where pallet exchange systems are already widely used, the pallet seating surface of the table is often the upper surface of two narrow rail-shaped guideways, but new and old pallets can be exchanged continuously. Because the work area of the table is often separated from the surrounding area by a splash guard room, protection of the seating surface such as the guideway on the table top is more important than dust prevention from the outer periphery of the machine while the machine is cutting. The main purpose is to prevent the intrusion and adhesion of cutting chips and contaminated cutting fluid. Even in large machines, if the machine has a pallet holder on both sides of the bed with a table in between, and two pallets are attached to and removed from the table interchangeably, the time that the top surface of the table is exposed is extremely short. .

る。 However, as mentioned above, the machine structure and line configuration in which pallets are carried in and mounted on the table from one side of the bed, and then separated and carried out before the next new pallet is carried in and mounted, are also used depending on the content of production. . In this case, the pallet guide path and seating surface on the top of the table will be exposed until the processed pallet is separated and carried out from the table and the next new pallet is carried in and mounted, preventing contamination from floating chips and dust on the outer periphery. Become defenseless. In particular, this dust accumulation continues even when the machine is stopped or not in operation, so protective measures such as covering the table with cloth are carried out as a countermeasure, but if the table size is large, repeating this work is complicated and is a safety issue. Also requires caution.

られテーブルへ移送される。 Next, I will explain the effect. First, to describe the pallet exchange operation, the pallet 4 is carried into the opening of the pallet holder 3 by another unmanned or manned conveyance means such as buried line guidance or rail running.
It is received by the lifting cylinder 8 of the pedestal 3 and lowered onto the guide rail 7. At this time, the concave engaged piece 17 of the transfer device 5 is waiting at a position directly below the convex engaged piece 18 of the pallet 4, and as the pallet is lowered, the convex engaged piece 18 is moved to the concave engaged piece. By engaging the piece 17 and rotating the feed screw 14, the pallet 4 is transferred from the pedestal to the table in the Y-axis direction along the guide rail and stopped at a predetermined position on the table. At this point, the clamping device 10 is activated and the pallet is lowered by a minute amount, and its lower surface is brought into contact with the top surface of the table and fixed. In response to the next command, the table is sent in the X-axis direction for machining work, but the convex engaging piece 18 on the pallet side is freely separated from the concave engaged piece 17 of the transfer device 5. When the machining operation is completed, the pallet 4 returns to the end of the bed 1 together with the table 2, and the convex engaging piece 18 re-engages with the concave engaged piece 17. Thereafter, the pallet is transferred from the table to the pallet holder 3 by the reverse procedure to the above, and is carried out of the machine by another conveying means, and then the next new pallet is carried in, and the pallet holder 3 is moved. It is received and transferred to the table.

ーはそのまま受台上に残る。 Next, the operation of the cover device will be explained. As shown in FIG. 6, the protective cover 21 of the cover device 6 is extended on the table 2. A pallet 4 is introduced onto the pallet pedestal 3 by external means, received by the lifting cylinder 8, lowered and placed on the guide rail. At this time, the pallet 4 is engaged with the pallet transfer device 5 in the Y-axis direction by the concave engaged piece 17 and the convex engaging piece 18. Subsequently, when the transfer device 5 is driven to move the pallet toward the table, the roller 27 of the hook 24 at the tip of the pallet is raised by the slope of the hanging block 31, and the claw of the hook 24 touches the hook of the cover 21. Uke 2
Multiply by 3. As the pallet 4 moves toward the table, the cover 21 moves from the hook receiver 23 to the hook 2.
When the pallet 4 has completed its movement onto the table, the cover is compressed and stored on the cover holder 19. Next, when the pallet 4 travels on the bed 1 together with the table 2 in the X-axis direction, the hook 24 freely comes out of the hook receiver 23, and the cover remains on the bed as it is.

復され、テーブル上面が露出することはない。 During cutting, the table surface is protected from dust by the pallet 4 and the gutter 32 around its outer periphery. When the pallet 4 returns to the front end of the bed together with the table 2 after the cutting process is completed, the hook 24 of the pallet re-engages with the hook receiver 23 of the cover.
At this time, the convex engaging piece 18 of the pallet engages with the concave engaged piece 17 of the pallet transfer device 5 at the same time.
Therefore, when the transfer device 5 is activated in response to a command to carry out a pallet, the cover 21 of the cover device 6 is pulled by the pallet and pulled out onto the table, and the roller 27 of the hook 24 is moved to the position where the cover 21 has finished being spread on the table.
However, as the hooking block 31 on the pallet holder 3 descends on the slope, the cover is disengaged from the hook holder 23 and the cover 21 stops. The pallet 4 moves further outward and stops at the delivery position with the external conveyance means. Thereafter, the application of the dustproof cover to the table top surface is repeated in conjunction with the loading and unloading of pallets from the table, so that the table top surface is not exposed.
