Definitions

• the invention relates to a method according to the preamble of the first independent claim.
• the method is used for discharging printed products from a flow and for forming stacks of the discharged printed products. Furthermore, the invention relates to a device for carrying out the method.
• Print products are transported during their processing, for example between successive processing stations, usually in the form of flow rates.
• the printed products lie, for example, on a conveying surface behind one another or overlapping one another (imbricated flow) and are conveyed substantially parallel to their main surfaces or the printed products are individually suspended by holding means, for example, suspended substantially transversely to their main surfaces.
• Printed products are collected into stacks for various processing operations (intermediate storage, packaging) and then further conveyed in stack form (rods, packages, etc.) and / or further processed.
• devices for forming stacks form the end of conveying streams, that is, all printed products fed in the conveying stream are stacked.
• the capacity of the stack further conveying or further processing devices is to be adapted to the flow rate of the flow or it is previously incorporate switches in the flow, which direct the flow to various stack-forming devices.
• the number of printed products that a device can handle for further conveying or further processing (e.g., tying or packaging) stacks per unit of time is substantially constant and can be handled smoothly as long as all the stacks formed comprise substantially the same number of printed products.
• Publication CH-667854 (or US-4683708) describes a system with which printed products can be ejected from a supplied imbricated stream optionally into a stacking shaft or conveyed further into another stack-forming device.
• the stacks formed are immediately packed in films and further promoted. This attachment is only applicable if the bulk of the printed products in the stacking shaft is discarded, or, if the delivery rate of the supplied scale flow is matched to the instantaneous capacity of the two, in particular the further stack-forming device.
• EP-A-0 218 872 a device for collecting different printed matter products is known, which has a plurality of at regular intervals of each other orbiting an orbit and from the top coatable pockets.
• the delivery flow in which the printed products are supplied is a stream of printed products which are suspended on retaining means and suspended transversely to their main surfaces.
• This delivery flow is conveyed via a stacking surface, wherein the stacking surface is arranged such that it protrudes from below into the delivery flow and that each of the printed products is temporarily applied at least with its lower part to the stacking surface or to a printed product already in contact with the stacking surface. If now a printed product to be added to the forming on the stacking stack, it is in the moment in which it at the Bearing surface is present or immediately before, released from the holding means. Due to gravity, the released printed product, guided by the stacking surface or by printed products already stacked on the stacking surface, drops down to a foot piece and stands there.
• the foot piece is removed for the further transport of a stack formed on the stacking surface, and the printed product or products standing on the foot piece are supplied by gravity falling to a further processing, for example a packaging between film webs.
• a further processing for example a packaging between film webs.
• a stack formed on the stacking surface which can consist of several printed products or even of only one printed product, it can also be pushed sideways by suitable means from the stacking surface.
• the discharge and stacking can be combined in one process step.
• products which are not discharged that is to say not intended to be deposited on the stacking surface, are not released by the holding means in the region of the stacking surface but continue to be suspended on the holding means and thus pulled over the stacking surface.
• the discharge and the stacking can also be carried out in two separate steps, characterized in that in front of the stacking area a switch is provided at which the NASAschleusenden printed products are discharged with their holding means from the flow and conveyed against the stacking surface, while printed products, the not be discharged, be promoted on the original conveyor line.
• a switch is provided at which the NASAschleusenden printed products are discharged with their holding means from the flow and conveyed against the stacking surface, while printed products, the not be discharged, be promoted on the original conveyor line.
• Figures 1 to 4 show schematically the principle of operation of the inventive method on the basis of successive stages of a flow with a conveying direction F, are conveyed in which conveying flow hanging held by holding means 1 printed products 2 substantially transversely to their major surfaces. From the flow individual print products 2 are discharged and further promoted as a stack 3.
• a stacking surface 4 projecting from below into the delivery stream is provided, the upper edge 4.1 of which lies (substantially perpendicular to the plane of the paper) in a plane parallel to the main surfaces of the printed products and at the lower end thereof, which is positioned below the delivery stream.
• a foot piece 5 is arranged.
• the stacking surface 4 may be oriented vertically or obliquely so that its upper edge in the conveying direction F is leading towards the lower end.
• Figure 1 shows a section of the flow in a stage in which the printed product 2.1, held by the holding means 1.1 hanging is, has arrived in a position in which it rests against the stacking surface 4.
• the printed product 2.1 should not be rejected.
• the holding means 1.1 passes the location above the stacking surface without being opened and the printed product 2.1 is pulled over the stacking surface.
• Figure 2 shows the printed product 2.1, which has passed the stacking surface 4 and is further promoted.
• the following printed product 2.2 which is conveyed by the holding means 1.2, has now arrived at the stacking surface 4. Since the printed product 22 is to be discharged, the holding means 1.2 is opened and the printed products 2.2 falls down from the stacking surface 4 down until it rests on the foot piece 5 ( Figure 3).
• FIG. 3 shows how a further following printed product 23 is also deposited on the stacking surface 4 or on the printed product 2.2 already resting on the stacking surface, in that the holding means 1.3 is opened.
• FIG. 4 shows how, by displacement of the foot piece 5, the stack 3, which has formed on the stacking surface 4 and which in the illustrated example consists of the printed products 2.2 and 2.3, is further conveyed by gravity (arrow W), for which advantageously a suitable not shown guide is provided.
• the stacking surface is thereby empty and, when the foot piece 5 is returned to its original position (arrow R), again ready for the formation of a new stack, which begins, for example, by the illustrated discharge of the following printed product 2.4.
• stacks which consist of a plurality of printed products
• individual printed products stack with only a printed product
• the printed products are shown schematically as a once folded sheet with a folding edge, which is directed upward, that is held by the holding means.
• other printed products are manageable, which consist for example of several nested sheets, or printed products that are multi-page and stapled or bound.
• the printed products can be conveyed with the folded edge or the stapled or bound back against the top, against the bottom or also arranged laterally.
• the main advantage of the method according to the invention is that it is so simple and that the device necessary for its implementation is also very simple.
• This device consists essentially of a conveyor line, which is realized, for example, as a transport chain with grippers for hanging conveyance of individual printed products, and one or more stacking surfaces with a displaceable foot piece or other suitable means for removing a stack formed on the stacking surface. Furthermore, control means are provided, with which the grippers in a position in the areas can be opened over the stacking surface, and optionally guide means with which printed products are guided out of open grippers, whereby an uncontrolled entrainment of the printed products is avoided by the removing gripper.
• a guide means is, for example, a guide link or guide band and is moved to be rejected products in the flow (see Figure 5) or is stationary in cases where all printed products are discharged.
• FIG. 5 shows an exemplary embodiment of a device for carrying out the method according to the invention.
• This has a chain 10 (shown schematically by a line), which is moved in the conveying direction F via a conveying path.
• Equidistant grippers (holding means 1) are arranged on the chain 10, on which folded printed products 2 are conveyed suspended over a stacking surface 4.
• Above the stacking surface 4 a means 11 for opening the gripper is installed, which means 11 for individually opening predetermined gripper can be controlled.
• the conveying path (course of the transport chain 10) can turn upwards in the region of the stacking surface 4 in order to facilitate the further conveyance of printed products which are not to be rejected, as shown in FIG.
• the stacking surface 4 and the foot piece 5 of the device shown in Figure 5 for carrying out the inventive method correspond to the stacking surface and the foot of Figures 1 to 4.
• the stacking surface 4 in its height displaceable (for example parallel to their orientation), as indicated by the double arrow V.
• Such a movable stacking surface 4 is for a researcherschleusendes Printed product in an upper, displaced for a not novelschleusendes print product in a lower position, for which purpose it is operatively connected to a correspondingly controllable drive.
• FIG. 5 also shows guide means 16 for guiding print products to be ejected from opened grippers.
• These guide means are to be designed in such a way that they can be moved into the delivery stream for printed products to be rejected and removed from the delivery stream for print products which are not to be rejected. They are realized for example as a pair of guide cylinders, which are arranged on both sides of the gripper and in their extended position ( Figure 5) lead a printed product from an open gripper and leave in its retracted position not numeroschleusende printed products.
• FIG. 6 shows a further exemplary embodiment of a device for carrying out the method according to the invention.
• the conveyor line is realized in this case as a rail 12 or rail arrangement (shown schematically as a line) on the individual transport means 13, each carrying a holding means 1, such as a gripper, are individually transportable.
• the rail 12 branches in a controllable switch point 14 in a rail 12.1 for further promotion of transport and holding means with notmultischleusenden printed products and in a leading over the stacking rail 12.2, on the transport and holding means, promote Stereoschleusende printed products are passed.
• the rail 12.2 may, for example, be directed downwards and have a controllable locking means 15, for example in the form of a controllable release, clock and counting wheel, at which locking means the gravity-fed transport means are stopped and buffered and as required against the means 11 for Opening the retaining means 1 are dismissed. Since on the rail 12.2 only conferenceschleusende and on the stacking surface 4 to be piled printed products are conveyed, all holding means 1 must be opened on the stacking surface, so that the means 11 must not be controlled to open. It may be formed, for example, as a stationary control link, which cooperates with corresponding control rollers on the holding means.
• the stacking surface shown in Figure 6 substantially corresponds to the stacking surface as described in connection with Figures 1 to 4. Since, according to the variant shown in FIG. 6, no printed products to be rejected from the delivery flow need to be drawn over the stacking surface 4, this can assume a position which is optimal for the discharge, but which prevents overprinting of printed products.
