Therefore, by appropriately rotating the motor 63, the traverser 21 can move the guide rail 5
9 can be reciprocated.

The pallet 1 is placed on the traverser 21.
Hooks 71 which can be disengaged from the hooks 29 provided in
The traverser 21 is provided with an actuator 73 such as an air cylinder for moving the hook 71 up and down. The actuator 71 is driven to move the hook 71 up and down. It is configured in.

With the above configuration, after the elevator device 23 is positioned corresponding to the desired pallet storage shelf 17, the motor 63 is driven to move the traverser 21 closer to the pallet 15 in the pallet storage shelf 17, and the traverser 21 Then, the hooks 71 provided on the pallet 15 are engaged with the hooks 29, and then the motor 63 is rotated in the reverse direction to retract the traverser 21 to the original position. The desired pallet 15 can be taken out.

As already understood, the elevator device 2
Of course, the pallet 15 on 3 can be stored in a desired pallet storage shelf 17.

As described above, after the desired pallet 15 is pulled out from the desired pallet storage shelf 17 of the shelf frame 19 onto the elevator device 23, the desired bar B on the pallet 15 is transferred to the bar processing machine 3. The material feeding device 25 for feeding is arranged on the right side of the shelf frame 19 as shown in FIG.

As shown in FIG. 2, the elevator device 23 is disposed on the left side of the shelf frame 19, and the material supply device 25 is disposed on the right side of the shelf frame 19. Needs to be moved to the position of the material supply device 25.

Therefore, the lowermost pallet storage shelf in the shelf frame 19 is formed as a pallet passage shelf 17L through which the pallets 15 can pass in the left-right direction. That is,
The pallet passage shelf 17L has the elevator device 2
3 is positioned at the corresponding height position, a guide rail 75 and a rack 77 (FIG. 3) which are continuous with the guide rail 59 and the rack 69 provided in the elevator device 23.
Reference).

Therefore, the traverser 21 provided in the elevator device 23 can run in the pallet passage shelf 17L from above the elevator device 23, and can move the pallet 15 through the pallet passage shelf 17L. Can be done.

On the right side of the shelf frame 19, a guide rail 79R connected to the guide rail 75 is provided on the right side of the shelf frame 19 to support the pallet 15 transferred from the elevator device 23 through the pallet passage shelf 17L. Is provided with a pallet support 79 having a frame structure.

As shown in FIG. 3, the material supply device 25 is disposed in the pallet support 79 and is provided on the pallet 15 supported by the pallet support 79. B is configured to be supplied to the bar processing machine 3.

That is, as shown in FIG. 1, the material feeding device 25 has a relationship with the bar processing machine 3 so that the bar B can be directly fed to the bar processing machine 3. It is arranged behind the bar processing machine 3.

More specifically, the material feeding device 25 comprises:
An elevating frame 81 (see FIGS. 3 and 4) extending in the front-rear direction (the supply direction of the bar B) is provided. The elevating frame 81 is raised and lowered by the operation of an appropriate number of elevating cylinders 83. On the upper surface of the elevating frame 81, a bracket 8 that can pass up and down inside the lattice-shaped pallet 15 is provided.
5 are erected at appropriate intervals. A feed roller 87 for pushing up the bar B on the pallet 15 and feeding the material in the front-rear direction is provided on an upper portion of each bracket 85 so as to be rotatable.

More specifically, as shown in FIG. 4, the lifting frame 81 is provided with a double chain chain sprocket 89 interlockingly connected to a material feeding motor (not shown). The sprocket 91 provided on the material roller 87 is linked and connected via a chain 93. Further, the material feeding roller 87 is appropriately inclined as shown in FIG.

Therefore, when the lifting frame 81 is raised by operating the lifting cylinder 83, the bar B on the pallet 15 can be pushed up by the feeding roller 87.
Since the material feeding roller 87 is slightly inclined, the pushed-up bar B is supported by the material feeding roller 87 and the partitioning roller 31 erected on the pallet 15.

When the bar B is pushed up by the feed roller 87 as described above, the feed motor is driven to rotate the feed roller 87 so that the bar B is moved to the above-mentioned position. The material can be supplied to the processing machine 3.

As already understood, according to this embodiment, the position of the pallet 15 with respect to the material supply device 25 is adjusted (positioned in the left-right direction in FIG. A desired bar B can be selected and supplied to the bar processing machine 3. In addition, the remaining material processed by the bar processing machine 3 can be returned and placed and stored on the pallet 15 again.

Further, as described above, while the bar B on the pallet 15 is supplied to the bar processing machine 3 and the bar B is being processed, the hook 71 of the traverser 21 is moved from the hook 29 of the pallet 15. The traverser 21 can be separated and returned to the elevator device 23.

Therefore, during processing of the bar B supported by the pallet 15 on the pallet support 79, for example, an empty pallet 15 is pulled out from the appropriate pallet storage shelf 17 onto the elevator device 23, and the empty pallet 15 is pulled out. By refilling the bar 15 with a new bar B and storing it in the pallet storage shelf 17 at an appropriate position, the bar B to be processed next can be prepared in the shelf frame 19.

That is, according to the present embodiment, a large number of various bars can be stored in the bar storage device 1 and a desired bar is selected and automatically supplied to the bar processing machine 3. And the remaining material after processing can be stored again. Further, a new pallet B is supplied to the shelf frame 19 while one pallet 15 is transferred onto the pallet support 79 and the desired bar B is supplied to the bar processing machine 3 for processing. It is possible to automate the bar processing and save labor.
