Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a library device such as a magnetic tape and an optical disk.

[0002]

2. Description of the Related Art An example of a conventional library device is disclosed in
-259451. As shown in FIGS. 7 and 8, the library device described in this publication accommodates a plurality of cartridges 101 radially from the outer surface on the same plane and is rotatable about a vertical axis 102. Is provided with a large cylindrical cell unit 100.

[0003]

By the way, in consideration of the increase in capacity, in the above-mentioned conventional library apparatus, it is necessary to store a very large number of cartridges radially in the same plane on the outer surface. In this case, since the outer circumference of the cell unit becomes large, the installation area of the library device increases in proportion to the square of the radius of the cell unit. When 24 cartridges are mounted on the same plane as shown in FIG. 9, the ratio of the cell unit total area 105 to the cartridge total area 106 is about 3.3 times, and the device size becomes too large. Further, since a useless space 107 exists inside the cell unit, it is difficult to save space.

An object of the present invention is to provide a library device which can realize space saving and large capacity in consideration of the above circumstances.

[0005]

According to a first aspect of the present invention, there are provided a plurality of cells each having a cell rotatable about a vertical central axis and capable of accommodating cartridges from the outer periphery in multiple stages in the vertical direction and in multiple rows in the circumferential direction. A cell unit, a handling device for delivering a cartridge between the cell and the drive device, and driving the plurality of cell units around in a horizontal plane
And a unit moving mechanism for moving an arbitrary cell unit sideways on the handling device.

According to a second aspect of the present invention, in the first aspect, the cell is capable of accommodating four cartridges at 90-degree intervals in the circumferential direction, and the unit moving mechanism moves the cell unit along a rectangular locus. It is characterized by being constituted.

According to a third aspect of the present invention, in the second aspect, two bosses spaced apart from each other are projected from a lower surface of the cell unit, and the unit moving mechanism includes two bosses of the all cell units. A guide floor having a rectangular guide groove to be inserted, and a loop-shaped member disposed below the guide floor and driven around the rectangular guide groove and directly connected to two bosses of each of the cell units. , And a driving source for driving the conveyor belt around.

In the present invention, a plurality of cell units are provided,
Since an arbitrary cell unit can be placed sideways on the handling device, the total cartridge storage capacity per unit plane can be increased by increasing the number of cell units while keeping the diameter of cells mounted in one cell unit small. Can be enhanced. In particular, when each cell can accommodate four cartridges in the circumferential direction and the cell unit is moved along a rectangular locus, the diameter of the cell is minimized,
In addition, the occupied area of the entire cell unit can be reduced, and space saving and large capacity can be achieved.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a library apparatus for a magnetic tape according to an embodiment, FIG. 2 is a side view, and FIGS. 3 and 4 are views taken along arrows AA and BB in FIG. This library device includes a drive device 2 for reading and writing a magnetic tape, a cell 1 on which a plurality of cartridges 7 can be mounted in four rows at 90-degree intervals in the circumferential direction on the same plane, and a plurality of cells 1 in a vertical direction. A motor 3 for rotating around a central axis, a plurality of cell units 4 each having one cell 1 in a case composed of a cylindrical outer wall and a bottom wall, a drive device 2 and cells 1 in the cell unit 4. Cartridge 7 between
Handling device 8 for transferring a plurality of cells,
The knit 4 is driven to rotate in a horizontal plane along a square locus.
And a unit moving mechanism 10 for moving an arbitrary cell unit 4 laterally to the handling device 8.

The handling device 8 is a hand 8 for directly transferring the cartridge 7 between the drive device 2 and the cell 1.
And an accessor 9 that enables the hand 8 to move up and down. The unit moving mechanism 10 includes a guide floor frame 5 having a square guide groove 5a, a loop-shaped transfer belt 11 disposed inside the guide floor frame 5 and driven to circulate along the square guide groove 5a, and a transfer belt. And two bosses 19 projecting from the lower surface of each cell unit 4 at a distance from each other, and are directly connected to the conveyor belt 11 after passing through the rectangular guide groove 5a. ing. The bearing 18 fitted on the boss 19 is slidably fitted in the rectangular guide groove 5a. 13a, 13b
Numeral 17 denotes a gear for transmitting the driving force of the motor 12 to the transport belt 11, and 17 denotes a pulley for holding the transport belt 11 so as to be able to move around. By inserting the gears 13a and 13b between the motor 12 and the pulley 17, the size of the motor 12 is reduced.

An overturn prevention plate 14 is provided above the cell unit 4 so that the cell unit 4 does not overturn due to the moment caused by the drive of the motor 12. In addition, the lower end of the cell 1 is
A caster 15 is provided to prevent a thrust load due to its own weight from being applied, and to prevent overturning, and casters 16 to prevent overturning are provided at the upper and lower ends of the cell unit 4. The guide floor frame 5 having the square guide groove 5a is configured by combining a base frame 6a and a rectangular frame 6b as shown in FIG.

In such a configuration, an arbitrary cell unit 4 can be laid sideways on the handling device 8 by driving the motor 12 to drive the conveyor belt 11 around. Then, the cell unit 4 facing the drive device 2
Since the cell 1 inside is rotatable around a vertical central axis, the hand 8 and the accessor 9 enable the delivery of an arbitrary cartridge 7.

In this library device, by using the cell 1 capable of storing four cartridges 7 in the circumferential direction,
The area ratio of the cell unit 4 and the cartridge 7 is reduced to save space. Further, a large capacity can be achieved by arranging a plurality of cell units 4 and arbitrarily arranging an arbitrary cell unit beside the handling device. Therefore, as shown in FIG. 6, even when six cell units 4 are provided so that 24 cartridges 7 can be mounted in one plane, the ratio of the total area of the cell units 4 to the total area of the cartridge 7 is about 2%. .8 times, so that the device size can be made smaller than in the conventional example. Further, by further increasing the number of cell units 4, it is possible to increase the capacity while saving space.

[0014]

As described above, according to the present invention,
Since the ratio of the total area of the cell unit to the total area of the cartridge can be reduced, there is an effect of saving space. In addition, there is an effect that a large capacity can be achieved by mounting a large number of cell units.
