Equipment for conveying printing plates

Abstract

The present invention relates to a device for conveying a printing plate (1), characterized in that a safety bar (4) is used to secure the printing plate housing (2) where the printing plate (1) is located in the support arm (3).

Description

Technical Field

[0001] The present invention relates to a device for conveying printing plates, which can be used in conjunction with a printing press. Background Technology

[0002] The document DE 10 2009 039 050 A1 describes a device combined with a web printing press, in which the printing plate container is transported by means of a lift. Summary of the Invention

[0003] The objective of this invention is to provide another device for conveying printing plates.

[0004] This task is accomplished by a device for transporting printing plates, characterized in that the printing plate housing (Druckplattenschale) containing the printing plate is restricted / secured by a limiting rod / safety rod (Sicherungshebel) in the support arm.

[0005] The advantage of the device according to the invention is that the printing plate shell will not detach from the support arm even during strong acceleration and deceleration. This prevents damage to the printing plate during operation. An additional advantage is that the device is suitable for supplying printing plates to sheet-fed printing presses with an array configuration.

[0006] Various extension schemes of the device according to the present invention are feasible:

[0007] The bumper can be operated via a control cam (Steuerkurve) during the pivoting motion of the load arm.

[0008] For this purpose, the bumper may have a cam roller that contacts the control cam.

[0009] The safety bar may have a retaining plate to lock the printing plate housing.

[0010] The bumper can be reset by a spring. Attached Figure Description

[0011] Further extensions are derived from the following description of exemplary embodiments and the accompanying drawings, which are shown in the drawings:

[0012] Figure 1 : Plate conveying equipment in a locked state, and

[0013] Figure 2 : Printing plate conveying equipment in the open state. Detailed Implementation

[0014] Figure 1An apparatus for conveying a printing plate 1 in a printing plate housing 2 is shown. The printing plate housing 2 is secured in a support arm 3 by a safety lever 4. The safety lever 4 has a retaining plate 5 at one end for locking the printing plate housing 2 and a cam roller 6 (e.g., a ball bearing) at the other end. The retaining plate 5 forms a hook and can be referred to as a hook. A rotary joint 7 is arranged between the retaining plate 5 and the cam roller 6, about which the safety lever 4 can pivot. The safety lever 4 is connected to the support arm 3 via the rotary joint 7. A spring 8 (e.g., a tension spring) holds the safety lever 4 in place according to... Figure 1 In this position, the retaining plate 5 prevents the printing plate housing 2 from detaching from the support arm 3 during the pivoting motion 9 of the support arm 3. This pivoting motion 9 occurs about the horizontal axis of the coupling mechanism.

[0015] Figure 2 As shown, during the pivoting motion 9, the cam roller 6 is contacted by the controlled cam 10 to release the safety lever 4. This unlocking is necessary so that the printing plate housing 2, along with the printing plate 1, can then be transferred from the support arm 3 to the printing plate memory. The movement of the cam roller 6 along the controlled cam 10 causes the safety lever 4 to overcome the reset action of the spring 8 and refer to... Figure 2 The rotating joint 7 pivots counterclockwise. As a result, the retaining plate 5 flips downward and the printing plate housing 2 is free. After the printing plate housing 2 is transferred, the cam roller 6 moves past the control cam 10, thereby causing the spring 8 to close the safety lever 4 again.
