The arm 11 is provided with guide tubes 12 and 13 that are inserted vertically into the tip and middle portions of the arm 11. It is fixed. Rods 14 and 15 are inserted into the respective guide tubes 12 and 13 so as to be vertically slidable, and the flanges 16 and 17 at the upper ends abut against the upper surfaces of the guide tubes 12 and 13, so that the rods 14 and 15 are suspended from the arm 11. Supported by lowering. Furthermore, arm 11
The position of the flange 16 of the rod 14 at the tip can be adjusted by a double nut 18, so that the length of the rod 14 protruding from the arm 11 can be changed. A magnet 20 is attached to the lower end of the rod 15 by a mounting plate 19, and the magnet 20 is attached to the lower end of the rod 15.
The magnet 20 is recessed at the top dead center of the loader mechanism 5 inside a frame member 22 formed vertically through the upper girder 21. A magnetic separator 24 is provided on the vertical beam 23 of the storage table 7, and the end faces of the blanks 6 loaded on the separator 24 are aligned and abutted, and the magnetic repulsion of this separator 24 separates each blank. Material 6... is magnet 20
It becomes easier to separate when it is adsorbed and rises.

The conveyor 8 is composed of two left and right parallel rail members 30, 30, and rollers 31 are arranged in parallel on the opposing inner surfaces of the respective rail members 30, 30, so that the conveyor 8 becomes a roller conveyor. ing. Shaft members 32, 32, 33, 33 whose axial direction is the length direction of the rail members 30 are fixed to both ends of the outer surfaces of the respective rail members 30, 30, and the rail members 30 on the press working apparatus 1 side The shaft member 32 provided at the end portion is supported by a shaft bearing member 34 provided on the vertical beam 23 of the storage table 7, and this bearing member 34 allows the shaft member 32 to rotate and swing up and down.

The center portion of a bar 40 extending in the left-right direction is fixed to the lower end of the rod 14 suspended and supported by the tip of the arm 11, and link mechanisms 41, 41 having a left-right symmetrical structure are provided at both ends of the bar 40. The link mechanism 41 includes a first link 42 whose upper end is pivotally connected to the end of the bar 40 with a pin 42a, and a second link 43 whose upper end is pivotally connected to the lower end of the first link 42 with a pin 42b.
The lower end of this second link 43 is integrated with the shaft member 33 of the rail member 30. Therefore, one end of the conveyor 8 consisting of the rail members 30, 30 is connected to the loader mechanism 5 via the link mechanism 41, and the other end of the conveyor 8 is connected to the blank material storage table 7.
is connected to. Respective rail members 30, 30
Both ends of a connecting bar 44 are loosely fitted into the shaft members 33, 33, and the bar 44 connects the shaft members 33, 33 with each other.
The spacing between is kept constant. At the top dead center position of the loader mechanism 5 shown in FIGS. 3 and 4, the interval between the rail members 30, 30 including the roller 31 is set smaller than the width dimension of the blank material 6.

As shown in FIG. 3, a stopper member 50 is suspended and fixed from the upper girder 21 of the blank material storage table 7, and the position of this stopper member 50 is determined when the conveyor 8 swings down using the bearing member 34 as a fulcrum.
corresponds to the position of the tip of.

Next, the operation will be described. When the mold mount 3 descends due to the press stroke of the press working device 1, the arm 11 of the loader mechanism 5 also descends together. As a result, the two rods 13 and 14 move downward, and the rail members 30 and 30 of the conveyor 8, which had been tilted downward toward the press working device 1 side, swing downward using the bearing member 34 as a fulcrum, and one end of the conveyor 8 moves downward as shown in FIG. The magnet 20 is received by the stopper member 50 and supported horizontally, and the magnet 20 passes between the two rail members 30 and descends to come into contact with the uppermost blank 6 and attract it. At this time, the link mechanism 41 is operating to expand as shown in FIG.
It is rotated around 2,33.

7 to 10 are a front view and a side view showing this operation of the rail member 30 as the magnet 20, that is, the loader mechanism 5 moves downward. This descending stroke progresses from the top dead center position in FIG. 7 until the rail member 30 and shaft member 33 come into contact with the stopper member 50 in FIG. acts, an outward rotational force is applied to the shaft member 33 integrated with the second link 43 of the link mechanism 41, and as the link mechanism 41 expands, the rail member 30 moves toward the shaft member 3.
The magnet 20 rotates outward as shown in FIG.
As shown in Figure 0, it is adsorbed onto the blank material 6.

When the mold mount 3 of the press processing device 1 starts to rise, the arm 11 rises, and the rod 15 moves upward due to the contact of the guide cylinder 13 with the flange 17, and the blank material 6 is lifted together with the magnet 20.
The blank material 6 rises and passes between the rail members 30, 30 whose interval is larger than the width dimension of the blank material 6. The blank material 6 that has been loaded and accommodated using the space below the conveyor 8 is lifted above the conveyor 8, and when the blank material 6 passes between the rail members 30, 30, the guide cylinder 12 is moved to the flange 16. Rod 14 to come into contact with
When the upward movement starts and the link mechanism 41 operates in the opposite direction, the rail members 30, 30 rotate inward and return to the narrow state with the original spacing, and one end is connected to the stopper member. 50, the rail members 30, 30 begin to swing upward using the other end as a fulcrum. The timing for changing the interval between the rail members 30, 30 before and after the blank material 6 passes is determined by adjusting the position of the flange 16 with the double nut 18,
The length of the rod 14 can be adjusted to an appropriate length.

When the blank material 6 reaches the lower surface of the frame member 22, the rod 15 continues to move upward, so that the upper surface of the blank material 6 comes into contact with the lower surface of the frame member 22, and the blank material 6 is forcibly separated from the magnet 20 and falls. . Therefore, the frame member 22 functions as a peeling member for the blank material 6. The blank material 6 falls onto the conveyor 8, and since the conveyor 8 is tilted downward toward the press processing apparatus 1 side at this point, the blank material 6 slides on the conveyor 8 and the conveyor 51 provided continuously with it. Then, it is automatically introduced and supplied to the press processing device 1.

As described above, the blank material 6 is waiting to be loaded on the storage table 7 for each press process of the press processing apparatus 1.
The loader mechanism 5 lifts up the sheets one by one, and the conveyor 8 feeds them into the press processing device 1.

As is clear from the above explanation, according to the present invention, the loader mechanism utilizes the movable part of the press processing device to move up and down, and there is no need to prepare a separate drive source.
The structure is simplified, the mechanism can be simplified, the maintainability is improved, and the space below the conveyor can be used to store blanks, achieving effective use of space.
