Description

The invention relates to a device for transporting printing paper rolls according to the preamble of claim 1.

DE 196 06 554 C1 discloses a device for transporting printing paper rolls comprising a main frame and a satellite frame. The main frame can be moved together with a satellite rack along or parallel to a printing press. The satellite frame can be moved out of the main frame and moved independently of the main frame in a direction that is perpendicular to the direction of movement of the main frame. Using the satellite rack, a print paper roll can be picked up from a roller bearing, with a paper roll taken in the satellite rack moved toward the press by means of the main frame. According to DE 196 06 554 C1, the main frame has a lifting device to lift a recorded in the main frame satellite frame from a floor or put on the same. In the state in which the satellite rack is slightly raised from the ground, the main rack can be moved along with the satellite rack along the printing press.

According to DE 196 06 554 C1, the recording and method of a printing paper roll relative to the printing press, thus using two components, namely the main frame and the satellite frame. The use of a separate main frame for moving the satellite frame parallel to the printing press requires a great deal of material and space and is therefore relatively expensive.

On this basis, the present invention is based on the problem to provide a novel device for transporting printing paper rolls.

This problem is solved by a device for transporting printing paper rolls according to claim 1. According to the invention, the or each frame is further movable in a second direction, which is approximately perpendicular to the first direction, relative to the printing machine, for which purpose the or each frame can be lifted by a lifting device from a ground, and wherein in this lifted from the ground position of the Frames the wheels of the chassis are adjustable.

The device according to the invention combines the functions of the separately formed according to the prior art components, namely the main frame and the satellite frame, in a single frame. This frame is movable in two directions, namely in a first direction parallel to the printing press and in a second, approximately perpendicular to the first direction extending second direction relative to the printing press. This is realized by the adjustable wheels of the chassis. With consistent handling characteristics with respect to a printing paper roll, the dimensions and mass of the printing paper roll transport apparatus are reduced. As a result, the power requirement of the device is reduced. Overall, lower costs result.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 to 3.

1 to 3 show a detail of a device according to the invention for transporting printing paper rolls relative to a printing machine in different perspective views. The device according to the invention comprises at least one frame 10 for receiving in each case at least one printing paper roll, not shown. The frame 10 has a chassis which comprises an impeller 11 at each corner of the frame 10. By means of the wheels 11, the frame 10 is movable in a first direction parallel to a printing press, wherein the wheels 11 are guided in this case in rails 12. The two rails 12 shown in FIG. 1 thus run parallel to the printing machine and provide the relative movability of the frame 10 parallel to the printing press. The mobility of the frame 10 parallel to the printing press is supported by a guide carriage 13 which is movable together with the frame 10 parallel to the printing press.

For the purposes of the present invention, the frame 10 is movable not only in the direction predetermined by the rails 12 first direction parallel to the printing press, but also in a second direction which is perpendicular to the first direction. For this purpose, the frame 10 can be lifted by a lifting device from a floor, wherein when lifting the rollers 11 are brought out of engagement with the rails 12. In this lifted off the ground position of the frame 10, the wheels 11 of the chassis are adjustable, namely in each case by 90 ° rotatable. Fig. 2 shows the wheels 11 in a relation to FIG. 1 each rotated by 90 ° position.

After rotation of the wheels 11, the frame 10 is lowered via the lifting device, so that the wheels 11 are brought back into contact with the ground, so as to allow the mobility of the frame 10 relative to the printing press in the second direction perpendicular to the rails 12 , The wheels 11 are again guided in rails 14 which are perpendicular to the rails 12.

The lifting device is formed by at least two push-off elements which are positioned on both sides of the frame 10. The Abdrückelemente are part of the frame 10 and moved together with the frame 10 in both directions. About the Abdrückelemente the frame 10 can be lifted symmetrically or evenly from the ground. The lifting device and the push-off elements are not shown in FIGS. 1 to 3 or covered by other assemblies of the frame 10.

In the embodiment of FIGS. 1 to 3, each of the wheels 11 of the chassis is assigned a separate electric motor 15 as the drive. The power supply of the drives 15 and other the frame 10 associated electrical devices via a pantograph, not shown, which is movable in a relative movement in the first direction parallel to the printing machine together with the frame 10 relative to a running rail 12. The current collector is preferably integrated in the guide carriage 13. In the region of a running rail 12, power supply lines are accordingly integrated into the ground, wherein the current collector is in contact with the power supply lines and thus provides the frame 10 with electrical energy. In a relative movement of the frame 10 in the second direction along the rails 14 and thus perpendicular to the predetermined by the rails 12 first direction of the current collector is stationary, as well as the guide carriage 13. The power is then supplied via a non-illustrated cable, which is unwound from a drum 16 and connected to the pantograph.

The connected to the pantograph end of the wound on the drum 16 and unwindable from the same cable is therefore in the second relative movement along the rails 14, which is perpendicular to the predetermined by the rails 12 first direction, as well as the current collector and the guide carriage 13 fixed educated.

The movable in two directions relative to the printing press frame 10 all the means for power supply and for controlling the same are assigned. Similarly, the frame 10 as a laser scanner trained sensors 17 are assigned, which serve the collision avoidance of the frame 10 with itself in the direction of movement of the same objects or persons.

In the embodiment of FIGS. 1 to 3, the integrated into the ground rails 12 of the guide of the frame 10 in the movement thereof along the first direction parallel to the printing machine, wherein power supply lines and the current collector are integrated into the ground. Alternatively, a guide rail can be arranged together with power supply lines above the frame 10. However, integration into the ground is preferred for ergonomic reasons. The same applies to the rails 14th

For receiving a printing paper roll with the device according to the invention is thus proceeded so that a frame 10 with rollers 11, which are in the position shown in FIG. 1, relative to the printing press is moved parallel to the same in the direction predetermined by the rails 12 direction. Once the frame 10 has reached the corresponding relative position parallel to the printing press, the frame 10 is lifted by means of the lifting device from the ground, the rollers 11 then get out of engagement with the rails 12. Drauffolgend the rollers 11 in the position shown in Fig. 2 90 ° rotated, and then the frame 10 with the rollers 11 deposited again on the ground and is brought into engagement with the rails 14.

Then, the frame 10 in the second direction along the rails 14, which is perpendicular to the predetermined by the rails 12 first direction, extendable or movable relative to the printing press. About gripping arms 18 is then a printing paper roll removed from a warehouse. After picking up a printing paper roll, the frame 10 is moved back in the direction of the rails 12. Once the corresponding relative position is reached to the rails 12, the frame 10 is raised together with the printing paper roll, to then rotate the wheels 11 of the chassis back into the position shown in Fig. 1. Subsequently, the frame 10 can be moved together with a printing paper roll in the first direction parallel to the printing press.
