Description

Device for transporting printing plates Technical Field The present invention relates to a device for transporting printing plates, which can be used in connection with a printing press. Background In DE 10 2009 039 050 A1, a device is described in connection with a web printing press, in which the printing plate containers are transported by means of an elevator. Disclosure of Invention The object of the present invention is to provide a further device for transporting printing plates. This object is achieved by a device for transporting printing plates, characterized in that a plate housing (Druckplattenschale) in which the printing plates are located is restrained/secured (gesichert) in a carrier arm by means of a restraint/safety lever (Sicherungshebel). The device according to the invention has the advantage that the printing plate shell does not fall off the carrier arm even in the event of a strong acceleration and deceleration of the carrier arm. Damage to the printing plate during handling can thereby be avoided. An additional advantage is that the apparatus is suitable for supplying printing plates to a sheet printing press in an aligned configuration. Various extensions of the device according to the invention are possible: the safety lever is operable by a control cam (Steuerkurve) during the pivoting movement of the carrier arm. For this purpose, the safety lever can have a cam roller (Kurvenrolle) which contacts the control cam. The bumper may have a retaining plate that locks the plate shell. The bumper may be reset by a spring. Drawings Further developments come from the following description of exemplary embodiments and the attached drawings, in which: FIG. 1A printing plate transport apparatus in a locked state, and FIG. 2 shows the plate transport apparatus in an open position. Detailed Description Fig. 1 shows a device for transporting printing plates 1 in a printing plate housing 2. The printing plate shell 2 is secured in the carrier arm 3 by a bumper 4. The safety lever 4 has a retaining plate 5 on one end for locking the plate shell 2 and a cam roller 6 (e.g. a ball bearing) on the other end. The retaining plate 5 forms a hook member (Haken) and may be referred to as a hook. A swivel joint 7 is arranged between the holding plate 5 and the cam roller 6, about which swivel joint 7 the safety lever 4 can pivot. The safety lever 4 is connected to the carrier arm 3 via a swivel joint 7. The spring 8 (for example a tension spring) holds the safety lever 4 in the position according to fig. 1, in which the holding plate 5 prevents the plate shell 2 from falling out of the carrier arm 3 during the pivoting movement 9 of the carrier arm 3. This pivoting movement 9 takes place about the horizontal axis of the coupling mechanism (Koppelgetriebe). Fig. 2 shows that during the pivoting movement 9, the cam roller 6 is contacted by the control cam 10 in order to release the safety lever 4. This unlocking is necessary in order to subsequently transfer the printing plate shell 2 together with the printing plates 1 from the carrier arm 3 to the printing plate store. By means of the movement of the cam roller 6 along the control cam 10, the safety lever 4 is caused to pivot about the swivel joint 7 counter-clockwise with reference to fig. 2 against the resetting action of the spring 8. Thereby, the holding plate 5 is turned down and the plate shell 2 is free. After the transfer of the printing plate shell 2 has been completed, the cam roller 6 moves over the control cam 10, so that the spring 8 closes the safety lever 4 again.
