Description

The Invention relates to an automatic handling machine, to a library system, a method for controlling a library system and a computer program product.

handling machines are used for automated delivery of video cassettes a video recorder to play or save videos or to a regular update, which often necessary to keep the stored information / videos permanently to secure. Generally speaking, such machines are there used where storage media is automatically read or written should be. These can be audio tapes, video tapes or data tapes with magnetic storage medium or optical storage (eg CD, CD-ROM, DVD, ...). Here are successively or successively and automatically the media from a plurality of storage bins one or multiple drives.

A Variety of such machines are known. For example there There are 3-axis robot robotic arms, such as the Sony Flexicart BFC-1 can distribute up to 70 cassettes on 4 video recorders. A disadvantage This system is the high mechanical complexity, in conjunction with high production costs. An alternative system is the Panasonic B AJ-CM32 Micro Cart System, which holds up to 32 DVCPRO cassettes to get managed.

Usually become a plurality of different cassette formats in audio / video studios used where, for example, the Panasonic MII, D3, DVCPRO, Sony D3, Digibeta or Betacam SP (large and small cassettes) too are called.

One Disadvantage of the known construction methods of handling machines is that they are for each only a special cassette will be developed. They usually include Gripping arms with gripping hook, which in defined cavities / receiving loads grab the corresponding cassette. As well as the recorder only for one (or two) different types of cassettes is intended, it is hardly possible or even impossible flexible to use the handling machines and another type of cassette adapt.

task The present invention is an automatic handling machine for automatic feeder from storage media to a read and / or write unit, which are flexibly adapted to different storage media can, cost-effectively to manufacture and is robust.

The Task is achieved by an automatic handling machine with a plurality of media receptacles solved for at least partially recording storage media. A Media receptacle is in particular an area of the magazine device, which preferably has an orientation in the form of a slot and is preferably of the height and width adapted so that a storage medium over a its edges can be pushed in and adapted from the depth so that a part an inserted storage medium protrudes from a front side of the magazine device. The front side of the magazine device is preferably vertical aligned. The media receptacle can be resilient elements (eg stainless steel spring or Injection spring hooks) which elastically spring on at least one side of the Press storage medium, so their slipping in the media recording or slipping out to prevent or reduce.

The Storage media include, for example, a disk, for. B. a digital storage element (such as a hard disk), a magnetic Tape or disk (s), or an optical medium. So come too Audio / video cassettes (of any format) or in general any Storage media, which is both the analog and digital Storage of information includes. Also are storage media with includes, which CDs, CD-ROMs, DVDs or similar Media included. These media are advantageously in one Housing - or cassette - at least partially received, which advantageously a substantially has rectangular or parallelogram-like basic shape.

Of the Handling machine includes According to the invention, a media transport device, which the storage media of a media recording reciprocally can transport to the drive unit. Mutually means in this context, in particular, that a storage medium of the media recording be removed from the handling machine to the desired Carried drive unit, supplied to the drive unit and removed from the drive unit after the read / write operation and any free media or other drive unit supplied can be.

in this connection is the drive unit according to the invention an independent one Device and independent of the handling machine operable. For example, with drive unit a DVD or VCR or audio recorder or data recorder meant. Also are devices comprises which only a reading function without recording capabilities exhibit.

Autonomous and independently operable in this context means in particular that the drive unit is a device which comprises all the necessary controls that it can be manually operated independently of a control of the handling machine or can be controlled separately. The drive unit is preferably a commercially available device which is used by default (eg for professional use). Usually such devices with a standardized data port such. B. Serial data interface, as provided by RS232 or RS 422.

According to the invention this, that too one Drive unit with a data and / or control interface is provided and optionally controlled separately by this or regulated, yet is considered to be independently operable.

There the drive unit is an independent unit some advantages: First, such devices can already in z. B. video studio so that with the purchase of the handling machine, no reader (eg video recorder) must be extra co-acquired. In addition, in the Case of a fault either the handling machine or the drive which is disconnected from the handling machine is easily replaced. There, how later explained The handling machine is flexible and different storage media types carry can, by replacing the drive unit, possibly with a Reconfiguration of the handling machine, another type of storage media be used. Like later explained is, is it possible in principle, to use any type of storage media, advantageously a drive unit is used that holds the appropriate storage media z. B. on a front side (front) of the device a piece far (eg one-fifth of the Depth), or storage media, the corresponding Piece in front of Project front, can move in. Unlike devices, which From the top with storage media are loaded (so-called "top loader"), one can speak of so-called. "Front loaders".

In Advantageously, the media transport device is arranged to that she a storage medium in a withdrawal direction from one of the media receptacles or remove a feed slot of the drive unit. The Storage medium, the removed storage medium along a Move the transport direction and the slot of the drive unit or to another media receptacle, with the feed motion counteracting the removal direction is. This is advantageously the Removal direction in one of 0 ° or 180 ° different Angle, preferably substantially perpendicular to the transport direction arranged.

In Advantageously, the removal direction is a horizontal Direction and the direction of transport is the essentially vertical one Direction. In other words: The media shots are preferably on top of each other essentially arranged. Furthermore, a commercial is preferred Drive unit (such as VCR) is used, which is usually the function offers that Storage medium (eg videocassette) on a front facing Front ejected from the recorder. The location of the media shots is chosen that yourself the storage media located in them largely directly above (or aligned to) one in the ejection position of the drive unit located storage medium.

So As seen, the media transport device moves the storage media in a U-shaped track. In this example, the first leg of the "U" is the first movement in the removal direction. Then follows the removal direction vertical movement in the transport direction and in succession is contrary the removal direction, ie along the second leg of the "U" s, the storage medium in the target position brought. Due to this relatively simple movement of the storage medium, Is it possible, how later is shown, the media transport device constructively simple to realize.

Favorable Way the media transport device of the handling machine a linear drive for moving the media transport device in the transport direction.

One Linear actuator is a standard and inexpensive available Drive element. Since linear drives are offered in different lengths, It is possible by using an example. Longer linear drive, a Variant of the handling machine to build, which a higher number of media footage offers.

In advantageously supported the media transport device does not move the storage media in a lateral direction, which to the removal direction and the transport direction is substantially perpendicular. Because in the lateral direction no, or no substantial offset between the Media mounts and the slot of the drive unit, is a promotion the storage medium in this direction is not necessary, thereby it possible becomes, the media transport device less expensive and thus cost-effective to realize.

Preferably, a standard available professional recorder (ie drive unit) is used. Such devices are usually designed so that several drive units (directly or directly) plaza on each other bar or can be arranged. This means that the top of the drive unit is so stably constructed that the handling machine can be placed directly on the drive unit and thus in particular its weight is borne by the drive. Preferably, the handling machine has substantially the same base or footprint as the drive unit. Of course, it is also conceivable that the drive unit is placed on the handling machine, but this requires a variation of the media transport device.

Further may alternatively or additionally the handling machine include a recorder recording, in which put the drive unit or at least partially included can be. In this case it is possible that the weight forces of the Handling machines are not supported by the housing of the drive unit but at least partially laterally past the drive unit via supports or side walls derived from the recorder recording.

Favorable Way, the drive unit is a commercially available drive unit which In particular, a video cassette recorder or a player is. Preferably the drive unit is operable without reworking with the handling machine. Without reworking means in particular that the drive unit at most changed insignificantly becomes. So can for example, not needed Rubber feet removed or the drive unit can be hooked, taped or otherwise Fasteners are attached to the handling machine. In particular, "without reworking" may also mean that no change or adjustment work is necessary, the interested layman despite instructions not possible are or would be.

Further can advantageously at the handling machine one or more Magazine devices, each with media shots for the partial Recording of one or more storage media are provided. This is particularly useful when a magazine device especially for a storage media form is optimized, but the drive unit is can read / write multiple media types and the magazine recording in which the or the magazine device to be included, offers enough space. In this case, the handling machine includes a Magazine receptacle in which a magazine device is received. The magazine device is preferably a housing, or a frame, in which a plurality of media receptacles are provided, in which the individual storage media at least partially (individually and / or in groups) can be included. Since the magazine device as a whole, preferably with a handle, can be removed from the handling machine, can be very quickly and effectively exchanged a variety of storage media become. Likewise it becomes possible thereby, over the employment of an alternative Magazine device the handling machine for the use of another Memory media type at least partially retool.

Favorable Way is the magazine device in the magazine holder in a, essentially perpendicular to the removal direction and transport direction, displaceable lateral direction. Advantageously, the magazine device in several positions in the magazine holder latching or arresting fixable. Thus, the magazine device just above the Einzugsschlitzes the drive unit to be positioned.

The individual storage media are, for example, substantially one above the other in corresponding media shots, which, advantageously as laterally limited (substantially horizontally aligned) slots or openings may be formed in the magazine device. The media transport device removes the storage media preferably in a removal direction, which are substantially horizontal and / or substantially perpendicular is aligned with the front of the magazine device. After removal the storage medium becomes vertical through the media transport device moved until they counter by a horizontal movement the removal direction of the drive unit or a desired Media intake supplied becomes. Since the automatic handling machine for different types of Drive unit can be reconfigured or converted, which i. d. R. different layers of their storage media receiving areas (infeed slot) have, the handling machine adapted by that different Magazine devices are used, or that a magazine device so within the magazine holder is displaceable, that thereby achieved the necessary alignment in said lateral direction can be. In this case, the magazine holder is preferred in lateral direction wider than the magazine device. Preferably locks the magazine device at the desired position within the magazine recording, or is there (eg. With tensioners) fastened. The Detent can, for example, by at the bottom of the magazine holder after above protruding knobs, protrusions and / or depressions happen, which in corresponding recordings or protrusions of the Grab magazine device and so for example by means of gravity the magazine device is positioned.

Preferably, the automatic handling machine has at least two gripping arms, which are suitable for attaching to lateral surfaces of the storage media to intervene or interact with them. Here, the lateral surface is defined in particular as lying substantially in the plane, which is essentially spanned in its orientation by the removal direction and transport direction. Since the storage media are usually rectangular or cuboidal, the side surfaces substantially correspond to the opposite sides of the storage medium. Here is a difference to see conventional handling machines, which usually have hook-shaped or other specific grippers that engage bores, notches or other prominent or past geometries of the corresponding storage media / cassettes and thus are not flexible adaptable to other media types. Since many standardized media types have opposing substantially parallel side surfaces, the present handling machine is very flexible in that it can access the storage media on these surfaces to different media types adaptable.

advantageously, has the media transport device on two gripping arms, each at least one front conveyor roller and at least one rear conveyor roller, the rear conveyor roller further away from a corresponding media recording than the front conveyor roller. The conveyor rollers Each gripper arm are respectively the same direction and in essence in the opposite or opposite direction to the conveyor rollers the other gripping arm drivable. Because the storage medium completely removed from the media receptacle and transported to the transport position should, at least two conveyor rollers on both sides of the storage medium advantageous to the storage medium during his promotion to lead safely. Also more than two conveyor rollers are possible.

As already described, the single storage medium is preferred such in the associated Media recording that one Part of the opposite lateral surfaces of the storage medium in removal direction opposite the front edge of the magazine device protrudes. The gripping arms have at their front - so the Storage medium adjacent - area conveyor rollers with a substantially perpendicular to the removal direction aligned (in particular vertical) rotation axis, which are driven so that theirs Rotation of the storage media in removal direction from the media recording to transport to a transport position can. The transport position is a position where the storage medium exclusively is held by the media transport device, so that with the media transport device in the transport direction is movable.

Further Is it possible, that only a part of the conveyor rollers (eg the conveyor rollers one of the gripping arms) are driven and in particular the or the other (n) gripping arms (eg the second gripping arm) either one directed to the corresponding side of the storage medium sliding surface, or a plurality (preferably at least at least 3) non-driven and directed to the storage medium roles.

The Gripper arms are advantageously around the axes of rotation of the rear Swiveling conveyor rollers. Furthermore, an electromechanical drive (eg a stepping motor) provided for pivoting the gripping arms. In particular, the gripping arms essentially in opposite directions pivotable. As a result, the construction of the gripping arms is structurally simplified, since only one axle bearing is needed, over which both the gripper arms, as well as the axes of the rear conveyor rollers are stored.

in this connection is advantageously the inner distance of each other facing or directed peripheral surfaces the rear conveyor rollers smaller than the width of the storage media and the rear conveyor rollers are so far at least partially elastically deformable that a storage medium between the rear conveyor rollers can be included. The axis of rotation of the gripping arms can, as already described, with the axis of rotation of the rear conveyor rollers preferably match and this axle can be attached to the media transport device which means that the relative position of the rear conveyor rollers is stationary to the media transport device. To a storage medium good grip, so the forces transmitted by rotation of the rollers substantially in feed forces of the storage medium in or opposite to the removal direction to redirect or implement, must between the conveyor rollers and the storage medium sufficient friction or adhesion to be available. This can be due to the described excess between rear conveyor rollers and the storage medium can be realized. The rear conveyor rollers are designed sufficiently elastically deformable to compensate for the excess. As material of the rear conveyor rollers is a foamed rubber, or foamed Elastomer, z. As LDPE, the elastic properties also can be supported by molding the rollers.

The front conveyor rollers can be made of the same material, but the elasticity is not is quite so important, since the tolerance / tolerance compensation on the Movement of the gripper arms is realized. For the front and rear conveyor rollers is a good and non-slip grip advantageous.

The preferred gripping of the storage media on the conveyor rollers is particularly gentle, because unlike the prior art, the Speichermedi so as not to come into contact with gripping hooks or the like. Conceivable are also driven by driven rollers belts z. B. made of resilient material (eg rubber).

alternative can also at least one axis of the rear conveyor roller elastic (floating) suspended be, such as on a resilient arm. Such a springy Arm can be rotatable with a bias on the media transport device be stored and include the axle bearing of the conveyor roller. So can achieved the necessary oversize compensation and a power transmission be realized by the drive to the storage medium.

Of the Handling machine is advantageously operable so that the media transport device in a release position no control element of the drive unit at least partially or substantially completely obscured. In this release position is the media transport device in front of the media recordings. So the drive unit can be operated independently and in particular are the controls (switch) and the cassette slot the drive unit for the User reachable.

Of the Handling machine advantageously has a cover, which at least in an open Location (first arrangement position) can be arranged, at which the access on all Media recordings and / or the magazine recording essentially released is. This is the loading position in the storage media or the Magazine holder can be replaced by the user, or Alternatively, storage media only added, replaced or removed individually become. In this Beladepostion is advantageously the media transport device positioned above the magazine device or in front of the drive unit.

The Cover is also in at least in a closed position (second arrangement position) can be arranged, with access to the Media recordings and / or the media transport device and / or protected the drive unit is.

Further is the cover preferably in a partially open position (third arrangement position) can be arranged, in which access to the drive unit essentially is released, however, access to the magazine holder and the transport device protected is.

The Cover can be designed as a plastic tub, which essentially cuboid and five Pages is essentially closed, and their sixth page in the closed position towards the front of the handling machine shows and before the media shots and the media transport device and the drive unit and the media transport device is located.

Of the Automat is usually operated in the closed manner and software controlled or -regulated over position information recorded by contacts or position switches arranged so that the Media transport device essentially can not move, as long as the cover is open is. This becomes a hazard the operator is excluded and accordingly the risk of damage reduced at the device itself. As in the partially opened Position of access to the drive unit is possible, the drive unit independently be served while at the same time the handling machine is well protected against environmental influences, such as shocks or dirt.

optional can also be provided on the cover a locking mechanism be, who holds the cover in the closed state, as long as the media transport device performs its tasks.

Around the drive unit associated with the handling machine, also as independent Operate the device to be able to Advantageously, the machine is operable so that the media transport device by the control device in a position before or above the magazine device is movable and so are all controls the drive unit (eg VCR) for manual operation accessible. The controls include the keyboard with on / off switch, the bobbins, ... and the storage media feed slot. This will make it possible that the Storage medium for the drive unit is manually replaceable.

The Invention Furthermore, a library system with a drive unit for storing Data on a storage medium and / or their reproduction and a Handling machine, which preferably the previously described Features partially or completely having. Accordingly, the drive unit is so to the handling machine aligned that the Drive unit operable on the one hand with the handling machine and also without manual work, so it can be operated independently. The automatic handling machine preferably has at least two gripping arms, which depending at least two each concurrently driven conveyor rollers for engagement a side surface have one of the storage media.

The invention further includes a method for controlling and / or regulating a library German: v3.espacenet.com/textdoc? DB = EPODOC & ... PN = EP0288241 comprising an automatic handling machine with a plurality of media receptacles for receiving storage media, a media transport device having at least two gripper arms and a drive unit, the gripper arms being aligned in a transport direction to a storage medium located in the media receptacle, comprising the steps of: substantially aligning the storage media Gripping arms in a transport direction to a storage medium in the media recording,
Move the gripping arms by a gripping movement substantially to the storage medium,
Removing a storage medium in a removal direction from its media receptacle by means of at least one driven conveyor roller located on one of the gripper arms, moving the media to a second media receptacle, or feeding a drive unit by means of the at least one driven conveyor roller.

by virtue of Transporting the storage media by means of conveyor rollers, the storage media are mechanically little stressed.

To Beginning of the transport process is or are preferred the front (s) Conveyor roller (s) brought into contact with a storage medium. This is preferably done via a Pivoting the gripping arms substantially on the sides of the storage medium so that she get engaged. This corresponds advantageously the axis of rotation (pivot axis) of the gripping arms with the axes of rotation their rear conveyor rollers. Likewise, however, is a gripping movement with rotation over a another axis of rotation and / or a translational or substantially linear gripping movement conceivable. This pivoting movement is preferred electromechanically driven, wherein at least one electromagnet or an electric motor (eg, a stepper motor) can.

Further Advantageously, the conveyor rollers engage substantially opposing surfaces the storage media. Since the storage media are often cuboid, For example, the media transport device may change via a change the distances the conveyor rollers easily adapted to different or different storage media.

Further comprises the invention is a computer program product, in particular in shape a computer-readable storage medium or in the form of a corresponding Signal sequence or a corresponding data stream, with computer-readable program elements, which after loading on a computer or in a computer network causes the computer and / or the computer network, the procedures of the invention or a preferred embodiment to control and / or regulate this method. In other words is a computer program product provided that is computer readable Having instructions which, when loaded and executed on a suitable system, the steps of the method according to the invention or a preferred embodiment to do this.

12 a side view of the handling machine with closed cover (alternative arrangement).

The automatic handling machine 1 essentially comprises a media storage system 50 with a magazine device 52 with media shots 54 in which the storage media 5 . 5 ' at least partially included. It also includes a media transport device 100 to remove the Spei media from the media 54 for feeding to the recorder 10 which corresponds to the drive unit. A control unit 30 controls and controls the individual processes.

1 shows a schematic view of the handling machine 1 , which is above the recorder 10 located. At the recorder 10 is the feeder slot 12 , which is used to record and output from the storage media, and the keyboard 16 characterized. Merely to clarify that the handling machine 1 with the recorder 10 does not form a mechanical unit, a small distance is shown between these components. Practical is the handling machine 1 mostly directly on the drive unit stand or rest and preferably only by gravity, possibly connected with frictional forces, rest on the recorder. In addition, however, projections, such as, for example, centering plates mounted on the outer sides, can also be provided on the automatic handling machine, which cover at least one area of the recorder and thus center. Usually, in a professional environment, the handling machine and the recorder (s) are mounted one above the other in a standardized metal cabinet or 19 "frame 30 , which has input / output data interfaces to sensors, such as limit switches / buttons 148 , Buttons / microswitches 146 / 147 on the right and / or left side, a barcode scanner 36 or the like, data about the state of the handling machine 1 to receive and control signals to the actuators, such as the media transport device 100 with the linear drive 40 provide.

In 2 is the linear drive 40 outlined a sledge 44 comprises, at which the media transport device 100 is attached. Above the linear drive 40 is his linear drive motor 42 shown. The linear drive motor 42 may be a commercial stepper motor, which (not shown) can drive a toothed belt, for example, via a gear reduction, within the vertically oriented linear drive 40 encircling and on which the sled 44 is attached. This is how the drive of the motor works 42 a movement of the toothed belt and the lifting or lowering of the carriage 44 , Due to the stepper motor control is a reproducible exact positioning of the carriage 44 possible in the vertical direction.

2 also shows some media footage 54 the magazine device 52 , being in an upper media intake 54 a storage medium 5 ' is shown. The state of the media recordings, in particular whether a storage medium is inserted correctly or not and whether the storage medium is inserted correctly, can be detected or detected by means of sensors which are designed, for example, as pushbuttons with microswitches. The state of the media recordings can be the user z. B. on bulbs (LEDs) or digitally via the control device and a computer connected to the controller (in particular with textual, half or full graphic) user interface or user interface represent.

The 3 and 4 show primarily the cover 56 in the opened state ( 3 ) and the closed state ( 4 ) Here, the cover 56 be changed over two guides by means of a pivoting movement between the positions. The guides are as guide rods 58 executed, each (directly or indirectly) on one of the side surface of the cover 56 and the handling machine 1 fastened or fastened at a pivot point.

12 shows an alternative embodiment of the kinematics for the cover 56 , Here is the continuous axis 57 on both sides of the handling machine on the carriage 60 rotatably mounted. The sledges 60 are each on a rail 62 displaceable substantially in the vertical direction to the front of the handling machine. When closing the hood 56 this is first pulled forward and then around the axis 57 by a predefined or predeterminable angle, in particular approximately by a quarter circle ( 90 Degrees), turned. When opening the hood 56 Preferably, the rotation is done first and then the hood is placed on the slide 60 moved backwards.

Also, a third intermediate position of the cover 56 be provided (not shown), in which the cover 56 according to 3 is offset by an amount up to the intake slot 12 of the recorder 10 to release (preferably substantially completely release) that a storage medium 5 can be issued or removed. This third intermediate position can through a longitudinal slot (not shown) of the storage of the guide rods 58 in conjunction with a support edge (not shown) at the front of the media storage system 50 between the recorder 10 and media storage system 50 be realized by the lower edge or edge of the cover 56 is placed on said support edge or edge. At the handling machine 1 At least one contact switch or proximity sensor is provided, which detects whether the cover 56 is in the open or closed or in the described third state, and which is electrically connected to the control device 30 connected is.

Another possibility is that a lower part of the hood 56 across from the rest of the hood 56 can be pushed up to the intake slot 12 of the recorder 10 release.

5 shows a part of a left side view of the handling machine 1 , with a part of the media storage system 50 , which is above the recorder 10 located. At the media storage system 50 is the linear drive 40 fastened, its carriage 44 in the transport direction T (preferably in a substantially vertical direction) is movable. On the sledge 44 is via a bracket or bracket 95 the media transport device 100 attached, which ensures each a storage medium 5 . 5 ' from a media recording 54 or the intake slot 12 of the recorder 10 to remove and / or supply there.

The media transport device 100 includes an upper guide plate 140 which advantageously has a suspension (not shown) on the bracket 95 is attached. The suspension is used in particular to better hold the holding forces on the guide plate 140 to distribute, otherwise the guide plate would have to be made of stronger material in order not to deform significantly. The suspension can also be made adjustable in order to align the transport device accurately. Thereof offset parallel downwards and preferably over a plurality of standoffs 144 attached, there is a lower guide plate 142 , Next are in 5 two storage media 5 and 5 ' shown in (preferably substantially horizontal) slots of the media receptacle 51 and intake slot 12 are plugged or received, that preferably protrudes a part.

To the sliding of a storage medium 5 on the lower guide plate 142 to improve, it may also be equipped with one or more substantially flat slide rails (not shown), which are preferably oriented in the conveying direction. These slide rails preferably have a semicircular or arched profile and are with the substantially flat side on the lower guide plate 142 attached. On the upper semicircular or curved side, the storage medium slides with substantially less friction and / or with more guidance against surface sliding directly on the lower guide plate 142 , In order to improve the guiding properties even further, the slide rails are advantageously each pairwise symmetrically rotated by a small angle with respect to the conveying direction. The slide rails can be designed as metal or brass profiles or plastic, such as PTFE.

In 5 For the sake of clarity, some components of the gripping device, such as electromagnet 180 or the drive device such as engine 170 and wave 174 not shown.

6 shows this arrangement in a plan view. On the left is the bracket 95 shown with the upper guide plate 140 connected is. At this upper guide plate 140 are the conveyor roller drive with drive motor 170 with pinion 171 , Wave 174 with gear 172 , the snails 160 and worm wheels 162 shown. Further, the gripping mechanism with electromagnet 180 , a short coupling rod 181 , a directional pad 182 , Coupling rods 184 and gripping arms 130 . 230 shown. The said components are mounted on the upper guide plate or stored accordingly, the mounting or bearing components are not shown for reasons of clarity.

The automatic handling machine 1 works as follows: In a first step is by the software of the control device 30 the next step is determined. If, for example, a storage medium 5 from the recorder 10 ( 5 ) is to be removed in removal direction E, first the recorder 10 via the control device 30 prompted the storage medium 5 output from the drive so that it faces the front of the recorder 10 something protrudes. Then the media transport device 100 over the linear drive 40 . 42 and 44 as far as in transport direction T (eg downwards) move that the front drive roller 150 essentially in withdrawal direction E (preferably substantially horizontal) to the storage medium 5 is aligned. In this state, the lower guide plate lies 142 substantially in alignment with the lower edge of the storage medium 5 or a small piece (about max 3 mm) offset (eg deeper). During the process in the direction of transport T are the front guide rollers 150 from the storage medium 5 spaced as in 7 will be shown. Once the correct position along the transport direction T (preferably the right vertical position) of the media transport device 100 is reached, the gripping mechanism attacks a storage medium 5 by the gripper arms 130 and 230 in opposite directions around their rear bearing axles 166 be panned. This happens, for example, via the electromagnet 180 which can attract a movable core (soft iron).

As an alternative to the above sequence, the media transport device may also be the first one 100 in front of the slot of the recorder 10 be positioned and then the recorder 10 via the control device 30 be prompted for the storage medium 5 from the drive.

It is also conceivable pivoting of the gripping arms by means of one or more stepper or servo motors, wherein a mechanical or elek trical / electronic coupling of the movements or the drive of the gripping arms 130 . 230 is advantageous. Out 6 It will be seen that when the electromagnet is attracted, there is a tensile force on the short coupling rod 181 is effected so that the directional pad 182 turns clockwise and compressive forces on the tie rods 184 be exercised. The gripping arms 130 and 230 are each about the rear drive axles 166 rotatably mounted and so causes the front conveyor rollers 150 against the side surfaces of the (dotted) storage medium 5 be pressed or rest on this. Alternative to the directional pad 182 is also conceivable that the two coupling rods 184 movably connected to each other and the short coupling rod 181 acts directly on this connection, which also pressure forces on the coupling rods 184 be exercised. Accordingly, the gripping arms 130 . 230 driven so that they are each about its axis of rotation in the direction of the storage medium arranged therebetween 5 to pivot towards or towards each other (especially in opposite directions) can be pivoted. It is also conceivable that the gripping arms can be pivoted in each case by means of corresponding stepping or actuating motors, wherein the pivoting is preferably carried out in such a way that the gripping arms in opposite directions (preferably as possible with respect to the storage medium 5 essentially centered or symmetrical) takes place. Furthermore, it is also possible that one gripping arm is static and the other gripping arm is pivotable towards the static gripping arm. Also conceivable is also a substantially linear displacement of at least one gripping arm to each other or to the storage medium 5 out.

In the next step, the storage medium 5 in removal direction E from the media recording 54 be removed or moved, which is preferably done via the conveyor roller drive. This includes the drive motor 170 , which is optionally provided with a gear reduction (not shown), and on its output shaft, a pinion 171 having. This is in engagement with the gear 172 , which rotatably on the shaft 174 connected to the upper guide plate 140 is stored. Furthermore, the shaft points 174 two snails 160 on which with worm wheels 162 engaged, which at the rear drive axles 166 are attached. At these drive axles 166 are (see 5 ) Furthermore, one per sprocket 190 and one rear conveyor roller each 152 attached. This is how the screw turns 160 , a rotation of the worm wheels 162 and corresponding rotations of the sprockets 190 and rear conveyor rollers 152 ,

The drive motor 170 is executable as a simple DC or AC motor or as a stepper motor.

At the front end of the gripper arms 130 and 230 So the ends that lead to the media recording 54 each are front drive axles 168 provided in the gripping arms 130 . 230 are rotatably mounted and one sprocket each 190 and a front conveyor roller 150 exhibit. The sprockets 190 the front drive axles 168 and rear drive axles 166 are over an endless chain 192 connected so that the rotational movement of the rear drive axles 166 on the front drive axles 168 is transmitted. This is how the drive of the motor works 170 in that the conveyor rollers 150 and 152 each gripper arm rotate in parallel. Furthermore, the conveying rollers of the different gripping arms run in the opposite direction, as in 8th is shown.

Alternatively, it is also conceivable that instead of the sprockets 190 Timing pulleys and instead of the endless chain 192 a timing belt is used.

Alternatively (or additionally) it is also conceivable that instead of (or in addition to) the sprockets 190 each gears with the same diameter (not shown) may be used, wherein the gears of each gripper arm with another gear are engaged, the axis of rotation parallel and preferably substantially centrally between the front drive axle 168 and rear drive axle 166 lies. So can a corresponding drive of the front conveyor rollers 150 can also be realized without chain and sprockets.

Alternatively (or additionally) it is also conceivable that instead of (or in addition to) motor 170 and the worm drive 160 with worm wheels 162 an alternative drive motor, a sprocket is used, and an extended endless chain (possibly via additional deflection sprockets) to both drive wheels 160 . 162 of each gripper arm 130 and 230 and passed over the sprocket of the drive motor.

The described movement of the conveyor rollers becomes the storage medium 5 removed from its receptacle and moved into the media transport device. Here it is on the one hand between the rear conveyor rollers 166 held. Further, it may be on the lower guide plate 142 rest and as in 10 shown are lateral guides 138 provided which prevent a shift in the lateral direction or a rotation about a vertical axis.

Conceivable are still separate drives of individual or all conveyor rollers by means of actuating or drive motors. The necessary synchronicity of the drives is then electronically via the control of the actuating, Stepper or drive motors accomplished.

Once the storage medium 5 is completely absorbed, it comes into contact with the end stop 148 , which with a button 149 is provided, which signals the control device that the removal process is completed. The storage medium 5 is now in the transport position.

Now the holding voltage of the electromagnet 180 switched off, so that the electromagnet 180 opens. Supporting can be in the electromagnet 180 a (bias) spring may be provided (not shown) which ensures that the plunger of the magnet with the short coupling rod 181 extends and so the gripping arms 130 . 230 open. Alternatively to the said spring in or near the electromagnet, the control pad 182 Also by a torsion or torsion spring, which acts on the axis of the control pad, be vrbunden, which rotates the control pad back to the starting position or to this.

Then the linear drive 40 operated and the media transport device 100 along the transport direction T before the desired media recording 54 placed in the storage medium 5 at least partially introduced. This is done via the steps of alignment along the transport direction T (preferably of vertical alignment) by means of the linear drive 40 , the pivoting of the gripping arms 160 . 260 (Preferably, the attraction of the electromagnet 180 ), the drive of the conveyor roller drive in the opposite direction as described above, thus conveying the storage medium 5 along the removal direction E at least partially into the desired media recording 54 and finally the renewed pivoting or opening of the gripping arms 130 . 230 (which in turn is preferred by releasing the electromagnet 180 happens). The in the 10 and 11 shown microswitch 147 . 149 or similar sensors detect, in particular, when the storage medium 5 has left the media transport device and sensors in the respective media recording 54 signal the control unit 30 when the storage medium returns correctly to the media recording 54 is inserted.

Alternatively, it is also conceivable that no electromagnet 180 but a stepper motor is used. This can be direct, or via a gearbox with the directional pad 182 be connected. Also, alternatively, the directional pad with the coupling rods 184 fall away and the gripping arms 130 and 230 each be controlled directly via a stepper motor.

10 shows a barcode scanner 36 which is oriented (preferably along the transport direction T or vertically), and at least one scanning beam (preferably a laser beam) 112 generated by a corresponding optics (eg a mirror 110 ) to the storage medium 5 is led, on which a barcode 5a is provided and is reflected from there at least partially to the scanner. Due to this structure, it is possible even over a relatively large distance the barcode 5a read. So, before, about the media transport device 100 a storage medium 5 has already been detected, whether the required storage medium 5 in the right media recording 54 is included. Likewise, over the laser beam 112 of the barcode reader 36 be checked, if ever a storage medium 5 in the appropriate media recording 54 is available. As barcode all markings come into question that allow a (preferably one-to-one) assignment, eg. Bar codes, 2D codes (array codes or stacked codes) and / or more specialized codes (hidden codes, stochastic codes, Royal Mail 4 State Customer Code (RM4SCC) or similar.

So can the barcode scanner 36 also at the beginning of a copy or read process for checking the present tapes or storage media 5 be used. This means that after closing the cover 56 , the linear drive 40 the media transport device 100 once completely traverses the entire driving range in the transport direction T and thus checked at each media recording, whether a storage medium 5 and the right storage medium 5 is included. Thus, the central controller 39 be communicated via the data interface (SOAP, TCP / IP), which storage medium should be contained at which location. If the required storage medium does not match the existing storage medium, the central controller may 39 immediately a warning message is issued.

9 shows an overview of the components of the control device 30 , It includes a central controller 39 which may be, for example, a microcontroller or a PLC (Programmable Logic Controller) or a microcomputer. This central controller 39 is with the components: vertical controller 32 for the control of the linear drive 40 , the media transport controller 34 the media transport device 100 , a barcode scanner 36 and optionally with the recorder 10 connected.

The vertical controller 32 essentially controls the linear drive stepper motor 42 and is in contact with respective limit switches (not shown) connected to the vertical controller 32 Position information about the position of the carriage 44 give. Furthermore, it can be in the barcode 5a contained information about the control device and a computer connected to the controller with (in particular textual, semi or full graphic) user interface or user interface is put. The media transport controler 34 controls the engine 170 the conveyor roller drive and the electromagnet 180 the gripping device. Further, it is in contact with a plurality of sensors or buttons which determine the position of the storage medium, the gripping arms 130 . 230 and the media transport device 100 detect.

The barcode scanner 36 also has a connection to the central controller 39 , As a barcode scanner 36 an industry-standard scanner, such as the IS4100 ScanQuest from Metrologic is suitable.

Optionally, the recorder can also 10 with the central controller 39 be connected. Commercially available professional video recorders have a control port or port, via the external control signals to the recorder 10 can be given or the recorder 10 Can output status information. So, after a storage medium 5 the recorder 10 was fed through the central controller 39 the signal will be generated that the recorder 10 an appropriate function (eg playing or recording) should begin. This optional feature limits the recorder / drive unit property described above 10 not one that the drive unit 10 stand alone that is independent of the handling machine is operable.

The connection of the mentioned peripherals 32 . 34 or 36 is preferably done via standardized interfaces, with serial connections are suitable such as RS 485, RS 422 or RS 232 , Unless the central controller 39 has sufficient data ports, the sensors (eg buttons 149 ) and also all actuators such as step, positioning and drive motors as well as electromagnets and display elements such as light emitting diodes etc. directly to the central controller 39 get connected.

Also optional is the central controller 39 a video encoder 33 comprising the input or output signals of the recorder 10 receives and pre-processing. For this connection, the SDI (serial digital interface), the RGB interface or the (F) BAS signal is suitable. For the communication of the central controller 39 with other external control devices, the Internet protocol is suitable for SOAP (simple object access protocol) or TCP / IP. So seen, the central controller 39 already include an intranet server, which, for example, is connected to the company / studio network, so that the operator via a correspondingly comfortable screen interface of any intranet PC control instructions to the central controller 39 or control the operation of the device. Also, the user can use industry-standard PC software applications such. B. Use Media Archive (R) IngestClient to manage the media archive and the required digital instructions (eg as a batch file) to the handling machine 1 to create. After completing all copy or read operations, the user can read a detailed report of the operations, duration, and success information. It is also easily possible via the open interface SOAP, direct control via customer-specific programming, such as Microsoft's. NET or J2EE.

As described, it is possible to use the handling machines 1 to convert without much effort to another storage media type. In this case, in a first step, a recorder is necessary 10 own, which can play the desired storage media type. Then, in a second step, the handling machine 1 opposite the recorder 10 aligned, as has already been described, and what may preferably be done by the automatic handling machine 1 just on the recorder 10 or mounted in a commercially available control cabinet (eg a 19-inch equipment cabinet from Rittal).

In a third step it is ensured that the media recordings 54 in the lateral direction against the intake slot 12 of the recorder 10 is aligned. This can be done either by a changed magazine device 52 , which is optionally offered for each storage media type specifically as a spare part, in the magazine recording 51 is placed, or that a magazine device 52 in the magazine holder 51 is laterally displaceable, is aligned accordingly.

If the width of the storage media type to be used does not match that required, the storage media transport device must 100 and in particular its gripping device are adapted. This can happen in different ways. Firstly, by releasing the connection from the bracket 95 to the upper guide plate 140 and releasing the corresponding cable connections, the entire storage media transport device 100 to be exchanged for an alternative. However, if only the lateral orientation of the conveyor rollers 150 . 152 towards the media shots 54 be changed, it may also be sufficient on a shift z. B. over slots or alternative mounting positions of the bracket 95 opposite the upper guide plate 140 to realign. Furthermore, a floating bearing (eg via elongated holes, displaceable bearings or the like) of the corresponding gripper arms is also conceivable for adaptability to the storage medium to be grasped specifically.

If the width of the desired storage media type is smaller, it is possible the conveyor rollers 150 and 152 to replace others with a larger diameter, so as to adapt the gripping device, or alternatively can with wider storage media 5 Be used smaller diameter conveyor rollers.

The automatic handling machine 1 may additionally be equipped with a counterweight (not shown) which controls the weight forces of the media transport device 100 , or at least part of it, absorbs. For this purpose, parallel to the linear drive 40 a belt / belt / rope or chain drive or the like. Be provided, which in the manner of a loop around an upper guide pulley, which substantially at the level of the linear drive motor 42 is fixed and about a lower pulley, which is fixed in the lower part of the handling machine, is guided, and wherein the pulleys are substantially parallel to the axis. At one point is said belt drive with the carriage 44 or bracket 95 or the like, so that the movement of the carriage 44 is transferred to the belt drive. Due to its circumferentially closed shape, one area of the belt always moves in opposite directions to the slide 44 , At this area, a counterweight is attached, and thereby becomes the linear drive 40 relieved. This is what a low-power linear drive can do 40 be chosen and / or its translation be changed, that the movement speed of the carriage 44 with the media transport device 100 is increased.

As a professional recorder 10 for example, Sony DigiBeta cartridges is, for example, the recorder HDW-1800 from Sony to call. This device has the dimensions width · height · depth of 427 mm · 174 mm · 544 mm. The top edge of its feed slot is 32 mm from the top edge of the recorder. Because the lower guide plate 142 the media transport device 100 to a height level below the lower edge of the storage medium 5 must be movable, the lower guide plate must by 32 mm plus the storage media thickness (in the vertical direction) below the lower edge of the footprint of the handling machine 1 be movable. The base of the handling machine 1 corresponds preferably to the base of the recorder so 427 mm x 544 mm. The height of the handling machine 1 is at least 500 mm plus the upwardly projecting structure of the linear drive 40 , The height can also be chosen significantly larger, so a significantly larger number of media shots 54 to be able to provide.

Different variants and embodiments of the present handling machine 1 and library system are freely combinable. In the illustrated embodiment, the storage media are located 5 in the media recording 54 one above the other. Alternatively, any other orientation (eg a horizontal orientation) is conceivable.

For example, the storage media can be next to each other. Also, the storage media can stand upright side by side, which means that in this embodiment, the drive unit 10 must be aligned accordingly. In this embodiment, the drive rollers engage 150 and 152 the storage medium 5 not laterally, ie in the horizontal, but in a vertical orientation. In this embodiment, the drive unit is 10 not above or below the handling machine, but positioned next to it.

11 shows the media transport device 100 from the bottom. You can see the buttons 146 indicating the position of the storage medium 5 palpate or grasp and (preferably mechanically) to the front microswitch 147 pass the switching state in turn to the control unit 30 pass on. As an alternative to the buttons with micro-switches, other sensors such. As light barriers or reflection light barriers or other based on optical, electromagnetic or other principles position sensors conceivable.

12 shows an alternative kinematics for the cover 56 , In this arrangement, it is in one axis 57 rotatably mounted, in turn, on two carriages 60 is rotatably mounted laterally (left and right). The sledges 60 are in or through two guide rails 62 led on or at the media recording 54 are attached. The sledges 60 are in the guide rails 62 guided so that they can move parallel to each other in the transport direction and in particular neither tilt nor can be moved out of the guide rails laterally or upwards. To the cover 56 To close, the operator pulls the hood on a handle (not shown) so far forward until the cover 56 around the axis 57 can rotate and at least partially covers the recorder with the lower edge or the lower area. Conversely, the operator pivots when opening the cover 56 upwards by a predetermined or predeterminable angle (eg about 90 °) and then pushes it with the carriage 60 until the stop of the guide rails 62 to the rear.
