Description

The invention relates to a delivery device on a sheet-fed rotary printing press according to the preamble of patent claim 1.

A delivery device of this kind is made DE 24 30 212 A1 known. The delivery device has a sorting device which deposits the printed copies optionally on two delivery stacks. The printed copies are subject to metrological quality control within the printing press. A circulating, first chain conveyor leads the printed copies to a first delivery pile. The first chain conveyor is associated with a removal drum with gripper systems, which is arranged downstream of a second chain conveyor. Depending on the determined quality, the print copies can be stored on the first or second delivery pile.

Out DE-OS 22 01 217 is a sheet delivery in modular design for a printing machine, the substrate is either a standard display or a special display fed, known. The boom consists of a sub-module, an attachable upper boom module and / or a special display module. The special display module has a separate chain circle and a delivery table, which is preferably arranged above the stack area of the upper construction module. In a further embodiment, the delivery stack is arranged within the circulating chain system. For safety reasons, the sheet can only be removed when the machine is at a standstill. To view the top stack in the special display module, this module has a transparent cover. The disadvantage here is that the sheet must be stopped for the sheet removal from the special edition module.

Another boom for a sheet-fed rotary printing press is off DE 43 22 324 A1 known, inter alia, has a modular structure. In this case, for example, a dryer section is arranged within the boom as a module. Furthermore, the boom is associated with a copy turnout, which is modular downstream of the last sprocket in the conveying direction of the sheet conveying system. Waste paper and sample sheets can be interpreted separately by activating the copy tray outside of the main stack. The disadvantage here is that inevitably increases the length of the printing press by the Bogenfördersystemen subordinate copy turnout and the stack.

The invention is intended primarily for medium and large format sheetfed offset presses, which are often used on the one hand in nonstop stack change operation in the boom, on the other hand in packet mode. Päckchenbetrieb means in this context that the printed delivery pile is separated into several smaller sub-stacks. This is done by manually installing wooden blocks. With this separation, the weight of the partial stack is to be reduced as much as possible and thus a lubrication of the fresh paint color can be prevented.

From the DE 198 19 491 C1 For example, a delivery device on a sheet-fed rotary printing press is known. In order to enable an improved sheet removal in the area of circulating sheet conveying systems and an increase of the process stability during laying, a switch is arranged on an endlessly circulating sheet conveying system leading to a delivery pile stack. For this purpose, a drum is provided for selective sheet removal in the conveying direction before the delivery pile as a switch. The drum is associated with the sheet conveying system and a sheet to be fed on the drum is deposited on a stacking system arranged below the drum.

The invention has for its object to provide a delivery device on a sheet-fed rotary printing machine, which avoids the disadvantages mentioned and allows a further increase in process stability when laying out.

The problem is solved by the training features of the main claim. Further developments emerge from the subclaims.

It is advantageous in the inventive solution that waste paper sheets or sample sheets are stored on a separate stack (stacking system) without disturbing the printing process. This increases the process stability when laying out. In addition, the separate stack can be used as an auxiliary stacking device. Another advantage is due to the fact that e.g. when a new print job in the Andruckphase resulting spoil sheets are immediately deposited on a separate stack. Intervention of the operator in the continuous stacking process of the sheets on the main stack (first or second delivery stack) is obsolete since the proof sheets (or spoil sheets) can be placed on the separate stack of the stacking system at any time. It is also an advantage that the risk of injury to the operator is appreciably reduced by a circulating sheet conveying system. Finally, it is advantageous to design the delivery device in a modular design. This represents a cost-effective, retrofittable design and allows the universal use of the delivery device on sheet-fed rotary printing presses.

Ideally, this device should be combined with machines with a waste paper Outfeed device are equipped. So far, the stacks are driven by pallet truck out of the boom, if no expensive material logistics is available. This process can be automated by this device. Likewise, the generation of small stacks (packet operation) is considerably simplified or automated.

The invention will be explained in more detail using an exemplary embodiment. Here are shown schematically:

1 a delivery device with a first delivery stack and a removal module,

2 a delivery device with a first and a second delivery stack and a removal module, and

3 to 35 various representations of the delivery system according to the invention in different stages of the process during the sheet delivery and processing of sub-stacks by means of a paternoster boom.

In a sheet-fed rotary printing machine is according to 1 a printing unit 1 , which may also be formed by a processing unit, for example a painting or other post-processing station, downstream of a delivery device in the conveying direction. The printing unit 1 consists of a blanket cylinder 2 (In a painting this corresponds to the forme cylinder) and a pressure cylinder 4 , On the inking unit and possibly the dampening unit will not be discussed here. The blanket cylinder 2 is with a printing cylinder 4 in functional connection, the impression cylinder 4 in the conveying direction a transfer cylinder 3 is arranged upstream of the sheet feed. Related to the blanket cylinder 2 with a simply large diameter are the impression cylinders 4 and the transfer cylinder 3 each with twice the diameter and two gripper bridges executed. The delivery device consists inter alia of an endless, circulating sheet conveying system 5 with several gripper systems 25 , wherein the sheet conveying system 5 , preferably as a chain conveyor, with a first, preferably pneumatically actuated, sheet guiding device 28 is trained. Outside the lower run of the sheet conveying system 5 is in close proximity to the sheet conveying system 5 an over the format width extending recess 30 within the first sheet guiding device 28 arranged. The lower run of the sheet conveying system 5 is in the area of the recess 30 a bow-guiding drum 11 assigned below. The drum 11 has at least one gripper bridge 26 on which with her flight circle 31 the recess 30 cuts. For the sheet storage is below the drum 11 a stacking system 10 this subordinated. The sheet conveying system 5 extends beyond a first stack of piles acting as a main stack 9 , In the conveying direction before this first delivery pile 9 is the bow conveyor system 5 the bow-guiding drum 11 assigned. The drum 11 is, based on a simply large blanket cylinder 2 , as a double-sized drum 11 with two gripper bridges symmetrically distributed on the circumference 26 educated. Likewise, the drum 11 with a simply large diameter and a gripper bridge 26 , but also with triple or multiple large diameters with a corresponding number symmetrically distributed around the circumference arranged gripper bridges 26 executable. The drum 11 acts as a switch for the selective removal of sheets from the circulating sheet conveying system 5 , This is the drum 11 preferably in a horizontally arranged part of the sheet conveying system 5 assigned to this and the one on the drum 11 guided bow is while on the stacking system 10 can be stored. The stacking system 10 is in the simplest form a pallet or a lattice box for receiving spoil sheets. In a further training at least slings and Geradstoßer for an exact edge formation can be arranged. The first sheet guiding device 28 is in the area of the recess 30 formed in two parts. The sheet guiding device upstream in sheet running direction 28 (first part) has comb-shaped prongs 33 with intervening open spaces. The downstream sheet guiding device 28 (second part) also has comb-shaped prongs 33 with intervening open spaces. The tines 33 Both parts of the sheet guiding device 28 face each other so that the open spaces (between the tines 33 ) in the recess 30 are integrated.

In training of the delivery device according to 2 with a first delivery pile 9 and a second delivery stack 17 is between the first boom module 6 and the withdrawal module 7 an intermediate module 18 with a portion of the sheet conveying system 5 arranged. Due to the modular design of the delivery device is the intermediate module 18 also as dryer section executable. The example is not fond of education. 2 limited. Alternatively, in the conveying direction of the removal module 7 even before the intermediate module 18 (with dryer section and / or second delivery pile 17 ) can be arranged. The intermediate module 18 is with a support surface 19 by means of a C-pillar upstream in the conveying direction 14 can be supported to the ground and the first boom module 5 is at the same time on the C-pillar 14 supportable. In a preferred embodiment, the intermediate module 18 on the support surface 15 of the withdrawal module 7 supportable.

The mode of action is as follows:
In a delivery device with a main stack like. 1 happens in the continuous printing operation by means of gripper system 25 guided arch the removal module 7 and the second boom module 8th , is delayed at a sheet braking device and the first delivery pile 9 fed and stored there.

If a non-stop stack change take place, the control device 24 operated, such that the bow from the gripper system 25 to a cam-controlled gripper bridge 26 the drum 11 is transferred correlated. At the same time, this is the sheet guiding element 29 from the horizontal about the axis of the rotary joint 27 has been pivoted, on the one hand, the sheet guide with the second sheet guiding device 20 on the drum 11 on the other hand, the space for discharging the arc in the recess 30 increased. The drivable drum 11 leads the arc at the second sheet guiding device 20 over, the gripper bridge 26 gives the bow free, which in the stacking system 10 is filed. The tray is by the preferably pneumatically acted upon, third sheet guiding device 22 supported. In a delivery device with two main stacks acc. 2 happens in the continuous printing operation by means of gripper system 25 guided arch the first boom module 6 and 25 , is optionally via the intermediate module 18 on the first delivery pile 9 or second delivery stack 17 on a sheet brake delays the delivery pile 9 or 17 fed and filed. For non-stop stack change gem. 1 when printing the sheets to the stacking system 10 supplied until the full delivery pile 9 can be driven off and replaced by a new one. In an education like. 2 the sheet tray is only between the first and the second delivery stack 9 . 17 redirected, so always a stack 9 or 17 can be changed.

In the 3 to 35 becomes the paper delivery in the sheet delivery 6 , the recording of the printed sheets on stacking boards, the automatic replenishment of stacking boards in the stacking hoist 28 , the takeover of the stacking boards from the Stapelhubwerk 28 in a transport device 31 , The transport of the partial stack by means of the transport device 31 to a recording device 33 at a further processing device 29 (eg a cutting machine) and the successive processing of the partial stacks in the further processing device 29 described.
