The material feeding roller conveyor 15 rotatably supports a substantially horizontal support roller 19 and a vertical roller 21 on a large number of conveyor brackets 17 standing upright while avoiding interference with the plurality of connecting plates 11. It will be.

Each supporting roller 19 of the material-feeding roller conveyor 15 is appropriately connected to a material-feeding motor (not shown) that is appropriately provided to perform a material-feeding action on the cutting machine 13. Further, the intervals between the respective support rollers 19 are provided so that an arm or a claw member for supporting the material M can be easily inserted in a carrying device such as a crane for supporting and carrying the material M.

In order to carry in and out the material M to and from the storage shelves 9 of each of the three-dimensional shelves 3 and the material feeding roller conveyor 15, the material storage device 1 is provided with a material transfer device 23 as a loading and unloading device. There is.

The material conveying device 23 is provided with lateral guide rails 25 provided on both sides of the three-dimensional shelf 3 in the longitudinal direction.
Is provided so as to be movable in the direction in which the plurality of three-dimensional shelves 3 are arranged side by side.

More specifically, the guide rail 25 is provided relatively high through a plurality of columns 27, and the material M fed by the material feeding roller conveyor 15 traverses the lower side of the guide rail 25. Are configured to pass through. The material transfer device 23, such as a gantry crane, is movably supported on the guide rail 25.

More specifically, the leg portions 29L on the front and rear sides of the gate-shaped frame 29 in the material conveying device 23 are movably guided to the guide rail 25 via wheels 31. The upper and lower guide members 33 are vertically provided inside the both leg portions 29L, and the upper and lower guide members 33 are vertically movable to guide both front and rear end portions of a lifter beam 35 extending horizontally in the front and rear direction. There is.

In order to move the lifter beam 35 up and down, an elevating motor 37 is mounted on an upper horizontal beam portion 29B of the gate-shaped frame 29. The elevating motor 37 and the lifter beam 35 are mounted. Are interlockingly connected as appropriate. As a mechanism for moving the lifter beam 35 up and down along the vertical guide member 33, for example, a vertical screw rod is rotatably engaged with a nut member provided on the lifter beam 35, and this screw rod is used for the lifting motor. Three
It is possible to employ various general configurations such as a configuration of rotating by 7 or a configuration of connecting a chain, a wire or the like wound on a drum rotated by a lifting motor 37 to the lifter beam 35.

That is, since the structure for vertically moving the lifter beam 35 may be a general structure, a detailed description of the structure for interlocking the lifting motor 37 and the lifter beam 35 will be omitted.

The frame 29 of the material conveying device 23 can move in the left-right direction while straddling the three-dimensional shelf 3. With the frame 29 positioned corresponding to the three-dimensional shelf 3, the lifter beam 35
By moving up and down, the lifter beam 35 can correspond to the upper and lower storage shelves 9 in the three-dimensional shelf 3.

Therefore, in order to carry the material M in and out of each storage rack 9 of the three-dimensional rack 3, the lifter beam 35 is used.
Is provided with a plurality of lifter arms 39 that support the material M. In the present embodiment, the lifter arm 39 is arranged in the left-right direction orthogonal to the longitudinal direction of the lifter beam 35 so that the material M can be carried in and out of the storage shelves 9 on both sides of the support column 5 of the three-dimensional shelf 3. It is movably installed so that it can project in both directions.

Further, the lifter arm 39 is divided into a plurality of groups, and each group is configured to be movable individually or simultaneously in the left-right direction.

More specifically, as shown in FIG. 1 and FIG. 2, the support arm 7 having a plurality of stages of storage shelves 9 for storing the material M is formed on the columns 5 of the plurality of three-dimensional shelves 3. Are provided so as to project in the left-right direction.

The lifter beam 35 is provided with lifter arms 39 divided into a plurality of groups. A rack 41 is formed on the lower surface of the lifter arm 39,
A pinion 43 is meshed with the rack 41. The pinion 43 is attached to a shaft 45, the shaft 45 is rotatably supported by a bearing (not shown), and is a servomotor such as a servomotor that drives the pinion 43 via a rotation transmission member 47 attached to the shaft 45. Motor 49 is lifter beam 3
It is attached to the lower surface of No. 5. The lifter arm 3
Although not shown in the figure, the slide shaft 9 is assembled so as to be slidable smoothly with an appropriate structure so as to be movable in the left-right direction with respect to the lifter beam 35.

Further, in order to support the material M on both ends of the upper surface of the lifter arm 39, a V groove, which is a material support portion 51a, is formed near the left end of the lifter arm 39,
A material support portion 51b, for example, a V groove is formed near the right end of the lifter arm 39.

With the above structure, when each motor 49 in each group is driven, the rotation is transmitted to the shaft 45 via the rotation transmitting member 47. The rotation of the shaft 45 causes the pinion 43 to rotate, and the rotation of the pinion 43 causes the rack 41 to move and the lifter arm 39 to move left and right.

Therefore, when the motors 49 in each group are simultaneously rotated in the same direction, all the lifter arms 39 can be projected in the same direction at the same time. Further, only the required motor 49 is rotated to project only the lifter arms 39 of the required group in the required direction,
Other unnecessary groups of lifter arms 39 can be retracted and retracted to the position of the lifter beam 35.

Further, by rotating the respective motors 49 in opposite directions, the lifter arms 39 of one group can be made to project in an appropriate direction and the lifter arms 39 of the other group in the projected state can be retracted. ..

That is, by appropriately controlling each motor 49 of each group, the lifter arm 3 of each group is controlled.
The protrusion and retreat of 9 can be controlled appropriately.

Therefore, by appropriately controlling the motors 49, the lifter arm 39 can be moved in association with the horizontal movement of the material conveying device 23. For example, the lifter arm 3 is moved in accordance with the horizontal movement of the material conveying device 23, for example, the moving speed or the moving distance.
It is possible to make 9 project out synchronously or to make it recede. Further, as a matter of course, the material conveying device 2
It is also possible to cause the lifter arm 39 to project or retract after the left and right 3 have moved the required distance, and conversely, it is also possible to move the material conveying device 23 after projecting or retracting the lifter arm 39. is there.

In FIG. 1, assuming that L is a length of the lifter arm 39 with a slight margin, and H is a protruding length of the support arm 7 to one side, the space between the columns 5 of the three-dimensional shelf 3 is L + 2H. The distance between the columns 5 can be significantly smaller than in the conventional case, and the overall size of the device can be reduced.

The material M is loaded and unloaded, for example, when the material M stored on the support arm 7 provided on the left column 5 in FIG. 3 is unloaded, the lifter arm 39 is projected to the left at the same time. Or, after the protrusion, the lifter beam 35 is moved to the left to position the material support portion 51a formed on the lifter arm 39 just below the desired material M. Then, the lifter beam 35 is raised and the material M is lifted by the material supporting portion 51a and carried out. When carrying out the material M stored on the support arm 7 provided on the right support 5, the material support 51b formed on the lifter arm 39 supports the material M to carry it in and out.
The operation is similar to the operation described above.

As another means for downsizing the entire apparatus, FIG. 2 shows a so-called shelf station management in which various materials M are stored in and out of the storage shelf 9.
As shown in FIG. 3 and FIG. 3, when the desired material M1 is taken out of the materials M1 and M2 stored in the storage shelf of the three-dimensional shelf 3, the material M1 is the station ST. 1 and the material M2 is stored in the station ST. The lifter arm 3 mounted on the lifter beam 35 is housed in the lifter beam 35.
Only the lifter arms 39 (three in this embodiment) of the group of 9 corresponding to the length of the material M1 are moved to the left side in FIGS. 2 and 3, and the lifter arms 39 of the other groups are moved to the right side. Everything, or lifter beam 3
It is retracted to the position of 5 so as not to be an obstacle when carrying out the material M1. The material M2 can be taken out by performing the above operation in reverse.

With the above-mentioned configuration, the distance between the shelves of the three-dimensional shelf 3 can be shortened and the station management of the shelves can be performed, so that the space can be saved and the materials M stored in the left and right shelves can be freely adjusted. Can be carried in and out.
In addition, since the structure is simplified, the cost can be reduced.

The present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes. For example, in this embodiment, the lifter arm 39 is incorporated in the lower portion of the lifter beam 35, but the lifter arm 3 is provided above the lifter beam 35.
It is also possible to incorporate 9.

As a construction for moving the lifter arm 39 in the left-right direction, for example, as shown in FIG.
Instead of 1, the chain CH may be stretched on the lifter arm 39, and the chain CH may be meshed with the sprocket 43. Further, various configurations such as a configuration in which the lifter arm 39 is moved in the left-right direction by using an appropriate actuator such as a fluid pressure cylinder, a linear motor, or a ball screw can be adopted.

[0042]

As can be understood from the above description of the embodiments, according to the present invention, a lifter beam which can be moved up and down is used for loading and unloading materials into and from a storage shelf provided on a three-dimensional shelf. Move the lifter arm horizontally for each group. Thus, the distance between the three-dimensional shelves can be shortened, and only desired materials can be loaded and unloaded, and the stations of the shelves can be managed. Thus, it is possible to save space and reduce costs by simplifying the structure.
