The bar material 6 supplied from the bar material supply mechanism 7 is
They abut against the partition member 53 and are aligned in the axial direction.

Next, the operation of the bar storage device 1 will be explained.

First, as shown by the solid line in FIG. 1, the shooter mechanism 3 is supported at the uppermost position by the lifting cylinder 4, and the swing mechanism 33 holds the shooter 31 in an inclined position downward to the right and connected to the strip 21. , the swinging bottom member 30A of the shooter 31 is connected to the opening/closing mechanism 32.
is held in the closed position.

In this state, when the bar material 6 is conveyed to the terminal end of the roller conveyor 8, the supply cylinder 25 is driven, the arm 23 is rotated, and the bar material 6 rolls on the upper surface of the strip material 21 while passing through the first partition. They are brought into contact with the member 29 and aligned in the axial direction, and this process is repeated until a predetermined number of bars 6 are accommodated on the upper surface of the strip 21, and then the first cutting cylinder 28 is driven and the bars 6 are placed on the shooter 31. will be supplied. The bar 6 supplied onto the shooter 31 rolls on the upper surface of the swinging bottom member 30A, contacts the second partition member 53, is aligned in the axial direction again, and swings on the left side of the swinging bottom member 53. It is placed on the upper surface of the moving bottom member 30A.

Next, the cylinder 52 of the alignment mechanism 34 causes the second
When the partition member 53 is opened upward, the bar 6 on the swinging bottom member 30A on the left side of the second partition member 53
are rolled toward the right end on the shooter 31, are received by the support member 44, are aligned, and are placed on the upper surface of the swing bottom member 30A on the right side of the second partition member 53. In a state where the bar 6 is accommodated up to the position of the second partition member 53 on the shooter 31 or above the position of the second partition member 53, the second partition member 53 is closed by the cylinder 52, and then the above-mentioned Similarly, a predetermined number of bars 6 are supplied onto the shooter 31 from the upper surface of the strip 21 and placed on the upper surface of the swinging bottom member 30A on the left side of the second partition member 53. In this way, the bars 6 are sequentially supplied onto the shooter 31 , and when the bars 6 are placed over the entire area in the left and right direction of the shooter 31 , the first partitioning cylinder 28 is driven to supply the bars 6 to the shooter mechanism 3 . supply will be interrupted.

After the supply of the bar material 6 is completed, when the swinging cylinder 46 is extended, the shooter 31 swings downward about the pivot pin 39 via the first link member 48 and the second link member 49, and the first While being held in a horizontal position as shown by the imaginary line in the figure, the lifting cylinder 4 is driven, and the shutter mechanism 3 is lowered along the guide rail 16 via each guide roller 17, 18 to the lowest position. Retained.

Then, the opening/closing cylinder 45 is driven and each connecting rod 40 is rotated via the transmission member 43 and each swinging arm 42, and the swinging rod fixed to each connecting rod 40 is rotated as shown by the imaginary line in FIG. Moving bottom member 30
A is rotated around the connecting rod 40 to the right-down open position, and the bars 6 placed on each of the swinging bottom members 30A roll to the right on the swinging bottom members 30A and their They fall from a relatively low position on the right end and are stored in the pallet 9 one after another.

In this way, when the bars 6 are stored in the pallet 9, the lifting cylinder 4 and the swinging cylinder 46 are driven, and the shutter mechanism 3 is again raised to the uppermost position and held in an inclined position, and the four swinging bottom members 3
0A is held in the closed position, and then the same procedure as above is repeated, but the next time the bar 6 is stored in the pallet 9, it is moved by the diameter of the bar 6 from the lowered position of the shutter mechanism 3. The shutter mechanism 3 is lowered to the upper position, the opening/closing cylinder 45 is driven, the four swinging bottom members 30A are rotated to the open position, and the next stage bar material 6 is stored in the pallet 9.

The second partition member 53 has the function of arranging the bars 6 on the shooter 31, once receiving the bars 6 and decelerating them, and placing the bars 6 on the right end side of the shooter 31.
The function is to prevent the layers from being stacked in double or triple layers.

Incidentally, when feeding the bars 6 from the shooter 31 to the pallet 9, it is also possible to control the opening/closing cylinder 45 so that the opening degree of the swinging bottom member 30A gradually increases. It is desirable to provide ribs of small height dividing the bar into four sections in the left-right direction to restrict the rolling of the first stage bar 6.

The lifting cylinder 4 is configured with an air cylinder,
It is also possible to construct the shutter mechanism 3 so that after the bar 6 is housed in the shutter 31, the shutter mechanism 3 is lowered by its own weight.

As explained above, the bar material 6 supplied from the bar material supply device 7 is corrected in the axial direction by the first partition member 29 and the second partition member 53, and the plurality of bar materials placed on the shooter 31 are Since the bars 6 are distributed and orderly stored in the pallet 9 by the four swinging bottom members 30A, the bars 6 can be stored in the pallet 9 efficiently and with volume efficiency, and can be stored with great ease of removal.

Further, since the bars 6 fall from a relatively low position on the right end of the swinging bottom member 30A and are stored in the pallet 9, the impact during storage is small and damage caused by collisions between the bars 6 can be prevented.
