Definitions
- the invention relates to an arrangement of sheet holding systems on storage drums in Turning devices of sheet printing machines.
- Turning devices working on the principle of three-drum turning consist of three sheet guide cylinders, the middle one as a storage drum with double-large Diameter is formed.
- Such a turning device enables the bow to be turned on the principle of Trailing edge of sheet and thus the optional application of a face print or a perfecting on the sheet in one pass.
- the storage drum each has two sheet holding systems for the front area and two bow support systems for the back of the bow, each diametrically are opposite.
- the sheet holding systems are for processing sheets of different lengths adjustable relative to each other in the circumferential direction.
- the bow support system for the front area of the bow is designed as a clamping gripper, is fixedly arranged on the body of the storage drum. That as Suction cup-shaped bow holding system is provided on a support element which is detachable on Body of the storage drum is arranged.
- the support element In the circumferential direction is the support element and thus the suction cups provided on the support element by means of an adjusting shaft, which is mounted in the drum leg, adjustable, on which one end of the control shaft (outside) via a gear stage a motor for actuating the Control shaft and a pinion is arranged at the other end.
- the pinion engages in a tooth segment a, which is connected to the support member.
- the control shaft is eccentric in the Drum shaft mounted.
- control shaft is rotated via the motor and the gear stage, which acts on the support element via the pinion and the toothed segment. With the support element the suction cups are adjusted relative to the clamping gripper.
- a disadvantage of such an adjustment device of the sheet holding systems is the large amount of parts. Many gear elements mesh with one another, which are subject to play, so that the adjustment of the sheet holding systems to the sheet size to be processed is inaccurate. The drilling and milling in the drum shaft leads to a weakening of the drum leg.
- DE 39 008 18 C1 shows a sheet guide drum with an inner shaft and one outer drum with at least one with respect to the inner shaft in the circumferential direction adjustable segment.
- the inner shaft and the outer drum through a multi-plate clutch are coupled with each other, the bow holding systems are assigned.
- the coupling sits between an end face of the segments and a bearing journal Wave. Via an externally operable tension rod and a clamping lever, the Coupling actuated and thus the connection between shaft and segment can be released. Then both can be adjusted relative to each other with the bow support systems.
- a disadvantage of this locking and releasing device is the large number of parts.
- the coupling within the storage area of the sheet guide cylinder is difficult to access for maintenance work with wear and soiling. In this case, too, the drilling and milling to weaken the thigh.
- the object of the invention is an arrangement of sheet holding systems on storage drums to create, which ensure a rigid structure of the storage drum and a simple Adjustment of the sheet retention systems guaranteed relative to each other.
- the rigidity of the storage drum base body is not weakened, since the Elongated holes are arranged on the operating side of the printing press in the storage drum.
- the adjustability of the sheet holding systems is ensured with simple means.
- This storage and arrangement of the gripper and suction system on the storage drum enables to arrange the coupling for the systems outside the storage drum. In order to easy accessibility of the coupling is guaranteed due to the good accessibility.
- Fig. 1 shows a schematic representation of a turning device 1 of a three-drum turn in a printing press and that upstream and downstream of the turning device 1 Printing cylinder 2.2 'with the rubber cylinder 3.3'.
- the turning device 1 is seen in the direction of sheet travel (indicated by arrow) from the transfer drum 4 with a single-large diameter, the storage drum 5 with double-large diameter and the turning drum 6 with single-large diameter.
- the storage drum 5 is equipped with two sheet holding systems 8, 9 for the sheet 7.
- the sheet holding systems 8, 9 for the front area are as gripper system 8 and for the rear area designed as a suction system 9.
- Gripper system 8 and suction system 9 are adjustable in the circumferential direction to each other, so that sheet 7 of max. to min. Format in front and rear area can be held on the storage drum 5.
- the Printing cylinders 2.2 ' have a double-large diameter. Of course you can also have a simple large diameter.
- the gripper and suction systems 8, 9 are each diametrically located in the storage drum 5 across from.
- FIG. 2 The detailed structure of the storage drum 5 is shown in FIG. 2.
- the storage drum base body 11 In the side wall 10 of the printing press is the storage drum base body 11 with its Legs 12 rotatably mounted.
- the gripper system 8 is located on the storage drum base body 11 assigned to the front arc segments 13.
- a central axis 14 In the legs 12 of the main storage drum body 11, a central axis 14 is rotatably mounted. With the central axis 14 is within of the side windows 17, a driver 15 is firmly connected, one at both ends Driver pin 16 has. Instead of the driving pin 16, a cross section can also be used another element may be connected to the driver 15.
- the driving pin 16 passes through the side window 17 of the main body of the storage drum 11.
- For the passage of the driver pin 16 17 are arcuate in the side window Elongated holes 18 provided.
- the length of the arcuate slots 18 corresponds to the required Travel (max. To min. Format) of the storage drum 5.
- the suction traverse is open the legs 12 of the storage drum base body 11 mounted. Fixed with the suction system 9, the rear arch segments 20 are connected.
- only one driver 15 is provided.
- the other side window 17 has another driver 15 on the central axis 14 to arrange.
- the clamping device on the storage drum 5, with the gripper and suction system 8, 9 are not separable or connectable to each other, is not shown.
- the central axis 14 is braked, the clamping device, not shown, is released and the storage drum base body 11, which is connected to the main drive, and thus the gripper system 8 is adjusted relative to the suction system 9. Then the sheet holding systems 8.9 are firmly connected to each other again.
- the invention has been described with reference to a storage drum 5 in a turning device 1. However, it can also be used on sheet guiding cylinders in straight printing machines for guiding the sheet in the rear area.
