Description

The The present invention relates to a device for feeding of printing plates to a platesetter comprising a magazine with a plurality of vertically spaced storage levels for Storage of storage containers for printing plates. Further is a first moving means for horizontally moving a Reservoir from the magazine in a separating device as well as a second movement means for vertical Moving the reservoir within the singulator in a separating position for removing printing plates from the Reservoir or to move the container in a dispensing position for dispensing the storage container from the singulator. Procedurally, The invention also relates to a method of handling of printing plates, in which the printing plates in storage containers be provided in storage levels of a magazine

to Illustration of printing plates, which in a subsequent Printing process used it is known these printing plates to provide in cassettes and several cassettes z. B. with different To hold printing plate formats in a magazine, so that for imaging a printing plate with a predetermined format from a cassette this magazine by means of a so-called single cassette loader, d. H. a charging device can be removed and in the single Cassette Loader a corresponding pressure plate from this cassette is isolated.

A corresponding device for handling these printing plates are provided in cassettes is from the DE 10 2004 020 693 A1 known.

Here Several cassettes are arranged one above the other in a magazine and stored in appropriate compartments. These subjects of the magazine are movable together in height, so that a desired cassette in the appropriate plane the charging device, d. H. Single Cassette Loaders are moved can pass and at this level to the single-cassette loader so they open in the single cassette loader and a printing plate can be singulated.

The Cassettes are outside the device with pressure plates loaded and are transported via a corresponding transport vehicle, which is detached from the institution, the magazine fed. The opening over the magazine a new cassette can be fed and the opening over which loaded the single cassette loader with cartridges from the magazine will be provided here in one level.

The Printing plates are delivered to a printing company so that they first must be manually inserted into a corresponding cassette. The cassettes have a blind, which opens can be so that plates can be put into it and which in the closed state, the plates from ambient light protect.

Become especially large format printing plates needed to illustrate them in a jar, so is a load of Cassettes at least problematic. Besides, the requirements are to the magazine then raise all cassettes together with extreme Effort connected.

From the US2007 / 0227387A1 It is known to provide printing plates in cassettes in a magazine.

Around to re-insert printing plates in the magazines of the magazine, The cassettes are initially horizontal from the magazine pushed out and then vertically in a charging device in a second Position transported. From this second position can either printing plates removed from the cassettes or the cassettes be moved horizontally in a Plattenbeladeeinrichtung. These Plattenbeladeeinrichtung has for a pivotable Level up the cassettes from a horizontal, towards can tilt an inclined plane. On this inclined plane plates can be loaded into the cassette.

Problematic in the described prior art, it is at least that if Printing plates are unloaded from the cassettes, no further cassettes can be moved from the magazine to the plate loading device and that in addition to the necessary facilities anyway like magazine and disk loader still further facilities necessary are.

It is therefore the object of the present invention, the described To reduce problems of the prior art.

This object of the invention is achieved by a generic device in which the separating position is different from the dispensing position and the dispensing position is assigned an output level above the first, ie the uppermost storage level of the magazine. In this way, a storage container can remain in the region of the singulation position and at the same time a further storage container can be brought into the dispensing position in order to then be transported to the dispensing level above the uppermost storage level of the magazine. According to the invention, it is not provided here that a special loading device is provided for loading the cassettes. The storage containers should then be provided on the top storage level of the magazine for loading.

Around Safe loading and unloading of cassettes in and out of the delivery position in the separating device or on the uppermost storage level To ensure, it is envisaged that between the Output position of the singulator and the output level above the top storage level of the magazine a substantially light-tight sealable bulkhead in the wall area of the separating device is provided. This bulkhead is for an edition or a transfer of cassettes into or out of the singulator to open.

Yet It is simply intended in a further development that the output level above the top storage level of the magazine immediately is provided on the top of the magazine itself and guide rails For receiving the dispensed storage container. On this way are no more complicated facilities for Providing the reservoir necessary for loading.

Around loading the cassettes on the top of the magazine even easier To design it is advantageously provided that the top of the Essentially from at least three pages and from above is freely accessible.

In In another embodiment, it is advantageous provided that the separating device above the output level another level for receiving a storage container and that in the area of this further level separating organs for separating printing plates and / or intermediate layers from the printing plate stack are provided from the reservoir. In this way Can a storage container in this additional level for recording of the storage container, d. H. in the singling position be brought and the level in which the issue position and the output level for the storage tanks is located then remains even during the separation of printing plates freely accessible around there cassettes for the output from the To provide magazine for reloading.

Around a reservoir safely in the singulation position to provide, in a development according to the invention a Hanging device for receiving a storage container provided in the area of the separating position.

To the Moving the reservoir in the singulator In particular, a lift is provided.

The storage containers may in particular be cassettes or stock levels such as those from the DE 10235897 A1 are known, act.

Procedurally, The object of the invention is achieved by a method of handling solved by printing plates, in which the printing plates in storage containers be provided in storage levels of a magazine. A first Reservoir is then in a first horizontal Transfer movement from the magazine to a separating device and then moved vertically in the separating device in a corresponding separating position. To move as described a lift is provided, which the reservoir vertically in the singulation position moved so that the reservoir are hung here can. While the first reservoir now is in the singling position or moved here, can According to the invention, a second reservoir first moved horizontally from the magazine into the singulator and then vertically in the singulator be transported in a delivery position. The second reservoir can then also from the singulation on the top The magazine will be moved out while the first Reservoir still located in the singulation position. On the top of the magazine can then the second reservoir again equipped with printing plates and / or intermediate layers become.

As described, it is advantageously provided that the first Hanging reservoir in the separation position is stored and the second reservoir with pressure plates is loaded while printing plates from the first reservoir be separated by means of separation organs.

One Embodiment to which the present invention should not be limited and from which more inventive Can give characteristics is shown in the following figures. Show it:

1 a feeding device for printing plates in a first process time,

2 the feeder in a second process time,

3 the feeding device in a third process time and

4 the feeding device in a fourth process time.

The 1 shows a feeding device 1 to the Feeding printing plates, which are in cassettes 3 . 3 ' . 3 '' are provided to a platesetter not shown here.

The cassettes 3 . 3 ' . 3 '' are for it in memory levels 12 a magazine 2 for such cassettes 3 . 3 ' . 3 '' stored.

The storage levels 12 are each transport organs 11 for moving the cassettes horizontally 3 . 3 ' . 3 '' in the plane in the direction of the double arrow 17 assigned. In alternative embodiments, these transport organs 11 also the cassettes 3 . 3 ' . 3 '' be directly assigned.

By means of a transport organ 11 can a cassette 3 ' which are on a storage level 12 of the magazine 2 is provided, in the direction 19 horizontally on a transport plane 18 a lift 6 to be moved.

The lift 6 with the transport level 18 is a singling facility 16 for separating printing plates from the cassettes 3 . 3 ' . 3 '' the feeder 1 assigned. By means of drive elements, such as. B. a drive spindle 21 can the transport plane 18 the separating device 16 in the direction of the double arrow 15 be moved vertically. For this purpose, in particular still further drive members such. B. drive motors for the drive spindle 21 be provided.

By means of the lift 6 can cassettes 3 . 3 ' . 3 '' either an issue position 4 , or a separating position 14 be supplied. Of course, this is also a supply to all memory levels 12 possible.

In the separating device 16 are in the range of the singulation position 14 Cassette holders 9 and separating organs 5 provided.

In the area of an issue position 4 includes the singulator 16 Continue in the direction of the double arrow 22 vertically pivoting bulkhead 8th which has a passage 23 for a cassette 3 '' from the issue position 4 to an output level 13 on the top of the magazine 2 can release. On the top of the magazine 2 are for receiving a cassette 3 '' guide rails 7 provided.

As in 1 is shown, first a cassette 3 ' from a storage level 12 horizontally in the direction of the arrow 19 to the transport level 18 of the lift 6 postponed.

These at the transport level 18 provided cassette 3 ' can then by a corresponding movement of the drive spindle 21 in the direction of the arrow 20 vertically in the singulator 16 be moved up. This way, the cassette can 3 ' the singulation position 14 be supplied. Here is the cassette 3 ' then from the cassette holders 9 recorded and held. Will the cassette 3 ' from the cassette holder 9 held, this is the transport plane 18 of the lift 6 Released and can again vertically in the direction of the double arrow 15 be moved so that they again a cassette 3 '' from the magazine 2 can record. This cassette can then again vertically in the direction of the double arrow 15 moved and so the issue position 4 in the separating device 16 be supplied. This procedural status is in the 2 and 3 shown.

As in 3 shown, when the cassette 3 '' from the lift 6 in the issue position 4 was provided, the previously closed bulkhead 8th in the direction of the arrow 24 pivoted vertically upwards, so now the passage 23 for the cassette 3 '' free is. By means not shown drive elements in the transport plane 18 and / or in the area of the output level 13 can the cassette 3 '' in the direction of the arrow 25 horizontally from the delivery position 4 to the output level 13 on the top of the magazine 2 be moved. Here are transport wheels 26 at the bottom of the cassette 3 '' in guide rails 7 at the issue level 13 one. The cassette 3 '' This makes it stable in a precisely defined loading position 27 on the top of the magazine 2 spent like it was in 4 is shown.

To prevent the cassette from slipping 3 '' at the issue level 13 To avoid, here are additional stops 28 provided a secure position of the cassette 3 '' guarantee.

As in 4 represented, now is in each case a cassette 3 ' . 3 '' both in the singulation position 14 the separating device 16 as well as in a loading position 27 at the issue level 13 , This was the Schott 8th open. Even with the bulkhead open 8th is by design the top of the cassette 3 ' by their hanging positioning in the cassette holder 9 before light exposure through the bulkhead 8th protected. A removal of not shown printing plates from the cassette 3 ' by a separating organ 5 can thus during the entire process of transporting the cassette 3 '' from the magazine 2 over the lift 6 to the output level 13 in loading position 27 be guaranteed. In particular, in a further step, the bulkhead 8th vertically in the direction of the arrow 29 be closed again. Then also the cassette 3 ' again through the transport level 18 taken over, vertically moved and into the magazine 2 be handed over and another cassette 3 can from the magazine 2 taken over the described way and in the singling position 14 brought and there the cassette holders 9 be handed over. While loading a cassette 3 '' at the issue level 13 Thus, different formats of printing plates from different cassettes 3 . 3 ' through the separating organs 5 be transferred to a plate setter, not shown.

In particular, a newly loaded printing plate 3 '' after a corresponding reopening of the bulkhead 8th back to the transport level 18 transported and into the magazine 2 are added while simultaneously a printing plate separation from the cassette 3 ' through the separating organ 5 he follows. Thus, a decoupling of the loading of cassettes 3 . 3 ' . 3 '' and the separation of printing plates made from these cassettes, wherein the transport of the cassettes and the separation of the printing plates in each case in the same device with the aid of the same transport elements as the drive spindle 21 and the transport level 18 can be done.
