JPS595974B2 - Video warehouse method - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a video storage system in which a large number of VTR cassettes, cartridges, movie film cartridges, etc. are loaded into a playback port and outputted using an external control signal.

Conventionally, a conveyor-type video warehouse has been proposed as this type of video warehouse.

In addition, a method has been devised in which a large number of material magazines are stacked on one rotating body, and two material magazines are retrieved by a machine hand after being primarily searched by rotation, and then loaded into a playback port. The former requires a long access time because it is conveyed by a conveyor, and high-speed hb access is difficult. In addition, in the latter case, in order to perform high-speed access, it is necessary to increase the rotational speed of the rotating body, and in order to ensure the rotational speed, the total weight of the rotating body is limited, which means that the number of material magazines in one stacker is limited. There are limitations and drawbacks. An object of the present invention is to eliminate the drawbacks of the prior art described above and provide a large-capacity video storage that can be accessed at high speed.

In order to achieve the above object, the present invention uses an annular stacker to enable short-time access, and a plurality of annular stackers are arranged coaxially to alleviate the capacity limitation of the annular stacker. In order to ensure the rotational speed of the annular stacker, each annular stacker is individually driven.

A specific example of the video warehouse system according to the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a magazine stacker, which is rotatably provided on one rotary shaft 2.

Each magazine stacker 1 is provided with a plurality of material magazines 4 arranged on the circumference and a gear 11 for transmitting a rotary stop to the magazine stacker 1. The rotating shaft 2 is fixed to a support 3.
The stacker is driven by applying the driving force from the drive mechanism 6 to the rotating shaft 12.
This is done by transmitting it to the tooth weight 11 of the magazine stacker section via the drive gear 5 fixed to the. Rotating shaft 12 of the stacker drive unit
The gear 5 is arranged so as to selectively drive the magazine stacker 1 which moves up and down according to an external control signal and transmits the driving force. When the search is started, the magazine stacker containing the magazine to be searched is rotated and the magazine to be searched is moved to the position of the magazine hand 7.

The machine hand 7 moves up and down along the support shaft 9, moves to a position facing the magazine to be searched, and extracts the magazine to be searched. Next, the machine hand 7 rotates around the circumference b of the support shaft 9, performs an operation to face the reproduction port section 13, and an operation to move up and down to the position of the reproduction port 10 to be output. The machine hand drive unit 8 raises and lowers the machine hand 7, rotates it, and controls the machine...
Generates and transmits power for hand movement. When the machine hand 7 faces the corresponding playback port 10, it loads the magazine to be searched into the playback port 10. The playback port performs operations such as starting, stopping, and fast forwarding and rewinding by 5 rewinds based on an external control signal. After the output is completed, the searched magazine is stored in the corresponding position of the magazine stacker 1 by the reverse procedure of the search. The method of driving the magazine Z stacker is not limited to this embodiment, and any method may be used as long as each magazine stacker is rotated independently. Although not shown in the figure, the magazine stacker 5 drive section, machine hand drive section, and regeneration port section are connected to a control section and controlled automatically or manually. According to the present invention, the rotation speed of magazine stackers can be increased compared to conventional circular stacker warehouses, and a large-capacity warehouse can be realized.

Claims (1)

[Claims] 1 Select a plurality of material magazines in which video information or video information accompanied by audio information is recorded on roll tape-shaped media, and use at least one magic hand that moves up and down to take out the material magazines and load them into the playback port. In a video warehouse where material magazines are arranged in an annular shape and driven gears are installed, a plurality of stackers are arranged coaxially with a stacker rotating shaft vertically erected via a support. A video warehouse system characterized in that one of the drive gears rotatably mounted and rotated via a stacker drive unit is geared to a driven gear of a specific stacker so that the driven gears of a specific stacker can be rotated individually.
