Description

10. The invention relates to a method and an arrangement for buffering and converting flat products, in particular printed products, which preferably occur in scale formation, according to the preamble of patent claims 1 and 10, respectively.

It is known to continuously supply sheet products of various types to a winding core and to wind them up thereon (see, for example, DE-PS 2 207 556, CH patent application 1 788 / 86-0). In printing technology in particular, the resulting printed products are preferably arranged in a shingled formation and are thus fed to the winding stations and wound up into coils. If the number of products to be processed in this way is greater than the capacity of a reel, measures must be taken as soon as the reel is full in order to be able to wind up the continuously occurring products on another, empty reel core. In the simplest, but uneconomical way, it would be, for example possible to interrupt the work process and to replace the full roll with an empty roll core during this break.

Furthermore, a method and a device are known from CH-PS 654 553 and CH-PS 654 554 which allow the main winding of the winding station to be exchanged with only one winding station with an additional intermediate winding without interrupting the working process. However, the products have to be wound up in double layers and divided into two separate shingled streams for further processing using a special device. If a winding is to be processed further in another working area, such an additional device for unwinding the double winding must be provided there. Depending on the capacity of the intermediate roll and because of the double layering of the wound products on the main roll, this process requires that the roll be replaced at relatively short intervals.

From DE-OS 33 04 219 a device for stacking printed sheets is known. The printed sheets fed via a feed conveyor line are transferred to a conveyor belt of the device. It is obvious that the phase position of the printed sheets, ie the information about mutual overlap or displacement of the printed products, is lost during this transfer and the printed sheets are inevitably arranged differently because of the feed at right angles to the conveyor belt. This device can therefore only be used if there is a subsequent intermediate stacking of the printed products and the changed phase position does not play a role in further processing. In many contemporary applications, however, it is just desirable or necessary to keep the phase position of the printed products as possible during all working days steps and also to maintain the intermediate storage. Without additional, complex and expensive measures, this device can therefore not be used for such applications. Furthermore, the mutual position of the printed sheets on the discharge path cannot be freely selected with this device. Another disadvantage is that it is not possible or only with considerable effort to replace the individual windings or buffer windings, since these are arranged in parallel next to one another, access to the individual windings is practically impossible and the device is therefore only to a limited extent as an offline buffer can be used.

In addition, it is known from DE-OS 25 44 135 to provide two alternately loadable winding stations, of which one product is fed while the full winding is removed from the other winding station. However, this solution can only be used to a limited extent in this embodiment within an overall process, since the coils for further processing have to be fed manually (or possibly with the aid of handling devices) to a further system, in other words that the device has a "dead end" within one continuous process. Additional stations must be used for unwinding. In addition, the right-angled course of the conveyor belts at the transfer points, similar to DE-OS 33 04 219, leads to problems since the mutual arrangement of the products is necessarily (undesirably) changed.

In many applications, for example in the printing industry, the products are obtained in a certain arrangement in various processing processes. For example, newspapers on conveyor routes are often transported with the federal government ahead, magazines with the flower ahead. Of course, the mutual arrangement of the Products vary with regard to a large number of other parameters (phase, top / bottom funding, spatial location, etc.). In order to be able to process products with different parameters in a subsequent, uniform process or special machines, it is therefore necessary to convert or standardize these parameters assigned to the products. Devices are generally known, for example, which convert the printed products (which would otherwise be superlative in the case of simple unwinding) wound into a product stream which is in turn undershot by winding. Previous devices of this type are always intended for special applications and therefore only allow such parameters to be converted to a limited extent. In addition, these devices do not provide any possibility of buffering products.

It is an object of the invention to provide a method and an arrangement which avoids the disadvantages mentioned above and can be used both as an offline buffer and as a functional arrangement for flexibly converting the parameters of the products within an overall system, with as little overall mechanical expenditure as possible, especially at winding stations.

It is a further object of the invention to provide a method and an arrangement in such a way that, even with very high working capacities, the loaded rolls can be exchanged without problems and thus unlimited offline buffering, as well as a flexible relationship between those of the device and the device. and removed products are achieved in terms of quantity, orientation and mutual position of the products; the arrangement according to the invention should be able to be arranged in a space-saving manner.

This object is achieved by the features mentioned in the characterizing part of patent claim 1 or 10.

The method according to the invention allows a continuous feeding of any, preferably flexible, flat products which are formed in scale form. The method is preferably used in connection with printed products. At least two winding stations arranged one behind the other in the conveying direction are fed via a common feed, a feed belt or feed conveyor. Depending on the quantity of the supplied products, which depends on the process speed, two or preferably more winding stations can be provided. The alternate loading of these winding stations can be controlled as desired. By means of a suitable arrangement of a common discharge belt or a similar conveying device, it is possible to simultaneously load a coil and to remove products from the device from another winding, the ratio of the products being fed in and out being controllable as desired. In addition, thanks to the free accessibility of the individual winding modules, it is possible to easily bring full windings from the device into a warehouse or to feed full windings from an intermediate store to the device without influencing or even interrupting the working process. By means of suitable measures, for example a wrapping device, the mutual orientation or position of the products at the exit can be changed as desired relative to that at the entrance or the feed belt within the arrangement. The phase position of the products can be kept constant during the buffering. This winding process ensures optimum flexibility of the application options when winding up or unwinding the products and enables continuous offline operation within an overall process or overall system.

The arrangement according to the invention contains at least two winding modules with exchangeable winding cores or windings. The feed belt, the winding planes of the winding modules and the discharge belt are preferably in a vertical plane. The feed belt or a feed conveyor is carried out in a straight line above the winding stations and has at least a number of branching points or points corresponding to the number of winding stations. The individual branches to the winding stations lead the products to the windings preferably on their underside. Each winding station has a connection to the discharge belt, which is carried out in a straight line under the winding stations. In order to be able to predefine the mutual arrangement of the products at the exit, it is advantageous to provide at least one device within the device for wrapping the reels or changing the input parameters of the printed product arrangement.

Although the invention is explained in more detail below with reference to examples from the field of printing technology, the invention can of course also be used in connection with any other flat products, for example flexible plastic parts. In addition, it is not a prerequisite that the products are fed in scale form. For example, products held at a distance from one another can be wound up or unwound in the same way by means of a clamp conveyor.

If, for example, high-frequency print products are to be fed to a further process step that has a lower work capacity than would be necessary to be able to accommodate the continuously occurring print products or if there is an interruption in one work step, it is necessary to provide an appropriate buffer. Known solutions, as explained above, either involve a considerable amount of mechanical effort or limit the possibilities of the work process. On the one hand, the present invention is intended to implement real offline buffering, i.e. the possible buffer capacity should be of any size. On the other hand, the buffer arrangement should at the same time offer the possibility of flexibly changing the various parameters which can be assigned to the manner in which the printed product is fed.

With previous buffer devices, only one function, namely the buffering of supplied products, could be achieved despite considerable mechanical effort. The invention The idea is to create a multifunction device that can perform a variety of functions with the least possible effort. This takes advantage of the fact that devices such as, for example, additional winding stations are necessarily present for buffering, which entail the mechanical requirements for further functions, in particular the change in the input parameters. This optimizes the total mechanical effort in an overall system. By using the device according to the invention at only one point in an overall system, the latter can be optimized in its entirety and made more flexible. There is no longer a need, for example, for the printing press, inserting and bundling devices, etc. to be coordinated in terms of their working speed, since the offline buffer forms the necessary interface both in this regard and in relation to other parameters.

The method according to the invention is explained in more detail below with reference to the block diagram in FIG. 1. It should be noted that this figure in no way refers to a spatial arrangement of the individual elements, but only shows the functional connections that are important for the method principle. Via a common input 2, the off-line buffer device 1, which contains a suitable number of winding modules 41-45, is supplied with printed products with a clock frequency t 1, an orientation o 1, a phase p and a mutual position l 1. Phase p or the phase position is to be understood as the mutual displacement of the printed products in the transport direction. Orientation o describes the spatial position of the printed products (e.g. flower or bunch in the direction of transport, cover page up or down, etc.) and the mutual position l indicates whether the printed products at input 2 are fed with insufficient or undershot . At an output 3, the printed products with a clock frequency t₂, a phase p, one Orientation o₂ and a mutual position l₂ given. At additional, depending on the number of winding stations in the off-line buffer 1, the number of inputs 21-25 empty or loaded reels with printed products can be fed to the offline buffer 1. The printed products wound on the winding cores can be characterized in an analogous manner with parameters l₂₁-l₂₅, o₂₁-o₂₅, which describe the "frozen" state of the products, etc. At outputs 31-35, full, empty or partially unwound packages can be removed from the offline buffer. [In general, input parameters are designated with x _i and output parameters with y _i in the following].

The windings supplied or removed via these inputs and outputs are equipped with printed products in such a way that they preferably have the same phase p, but otherwise each winding itself can contain printed products of its own orientation o and mutual position l. At least one of the winding modules 41-45 of the offline buffer 1 can change the position 1 and the orientation o of the printed products fed to it via one of the inputs 2, 21-25. In addition, a direct connection 5 between input 2 and output 3 can be provided. Each winding unit 41-45 can contain a main and a buffer winding station or also additional devices for converting the parameters.

Inputs 2 are connected to the individual winding modules 41-45 and output 3 via interfaces 51-55, which function as turnouts. Similarly, the outputs of the individual winding modules are connected to output 3 via interfaces 56-60. Products can of course be fed to the input 2 from different systems, ie a multiple input 2 can be provided. It can also be seen from FIG. 1 that the output 3 is simultaneously direct from the input and / or from one or more winding modules can be supplied with products, these being spliced together by suitable merging at the interfaces 56-60 to form a uniform scale formation or individual printed sheets or bundles subsequently being inserted into them. For example, a buffer clock according to CH-PS 610276 or US-PS 4,072,228 can be used for this purpose, as is described in more detail in connection with FIG. 5.

Printed sheets printed on one side are, for example, undershot and with their printed side facing up the input 2 with a clock frequency t 1. If the printed products are to be produced at the output with their underside upwards and with a lower clock frequency t₂, then input 2 is to be connected via a switch of the switch group 51-55 to a winding module, at the output of which the printed products can be led out with the desired orientation o₂ . It is obvious that in this example the clock frequency can only be changed if a part of the printed products is buffered. This happens because, for example, a winding of a first winding unit is filled. The input 2 is then automatically connected to a second winding unit. While the resulting printed products are now buffered on the roll in the second winding station, it is possible to remove printed products with the desired clock frequency t 2 from the roll of the first winding module. The desired clock frequency t2 is achieved in that the printed products are unwound from the corresponding second winding module at the desired speed and fed to the output 3. Of course, the winding as a whole can also be removed from this winding module via the corresponding output.

The following functions or their links within a winding module are possible: Change from: mutual situation orientation Clock frequency Type 1 x Type 2 x Type 3 x Type 4 x x Type 5 x x Type 6 x x Type 7 x x x Type 8 (none of the parameters are changed)

Of course, in the case of special process sequences, it may be necessary to change further parameters, possibly also phase p, so that this table represents only one example of the functions that can be carried out within a winding module. It is of course possible to link the functions by connecting at least two winding modules in series, that is, for example, to obtain a type 6 winding module by connecting two types 2 and 3 modules in series. For this purpose, additional switches 71, 72 are provided within the buffer device 1, which in the arrangement shown permit, for example, a series connection of the winding modules 41, 42 and 44.

Since empty and full rolls can be fed to and taken from the offline buffer via the exits and inputs 21-25 or 31 to 35, even if output 3 is idling, i.e. if no printed products are removed there, the latter can permanently print products via input 2 are fed. The buffer capacity of the offline buffer can be increased as desired by temporarily storing the full packages from offline buffer 1 in a separate warehouse. Depending on the area of application, the offline buffer can contain two or preferably more winding modules 41-45. Conversely, full windings can be fed from such a store via the inputs 21 to 25 of the offline buffer arrangement and by unwinding are output in a suitable winding module 41-45 with desired output parameters y _i at output 3 without products being produced at input 2.

The present invention accordingly allows, on the one hand, to receive the resulting printed products in the off-line buffer and, if necessary, also to temporarily store them, and on the other hand can be used as a functional arrangement for converting the parameters x _i which can be assigned to the products. The output parameters y _i are functionally dependent on the input parameters x _i , the possible functions on the one hand through the types of the winding modules within the arrangement (see table) and on the other hand through their mutual additional connections, for example 71, 72 in FIG. 1, given are. The buffer arrangement can be expanded by coordination with an additional, separate warehouse. In the manner described, products wound onto a winding can be inserted, converted and directly wound onto a new winding (by appropriately switching the switches 71, 72) or taken out at the exit 3 for further processing via the inputs 21-25.

The arrangement is controlled by a computer unit, which monitors the state of the individual winding modules and takes over the functional control of the system. In addition, sensors for monitoring can be provided in the area of the conveyor lines, which detect any faults (for example an interruption of the scale flow). A central computer is preferably used to at least feed and discharge the products via the inputs and outputs (2, 3, 21-25, 31-35), the winding processes of the individual winding modules (41-45), the position of the switches (51 -60, 71, 72) and the connections between the winding modules (41-45) and the inputs and outputs (2, 3, 21-25, 31-35) by means of, for example, optical Sensors monitored and / or controlled. With complex winding modules, it may be necessary to provide additional decentralized computer units.

Instead of using coils, the method can also be used in connection with other storage units, for example pallets or cassettes, the individual winding modules being adapted accordingly to these storage units, that is to say, for example, the products which are used as storage units via the inputs 21-25 can be fed, record and pass on to output 3.

An example of an arrangement with three winding modules for carrying out the described method is shown in more detail below. In Figure 2, the common feed belt 11, the common discharge belt 12 and three winding modules 41, 42, 43 can be seen. Via a first group of switch devices 51, 52, 53, a conveyor connection 61, 62, 63 leads to the corresponding winding modules 41-43 and feeds the printed products to them from below. The winding modules each contain a winding station 8 with winding brackets 46-48, which are used for winding or unwinding windings 10. The windings 10 have a winding core 9, which allows the windings to be exchanged in the winding stations. A possible design of the winding stations, the winding and unwinding or the way of changing windings or winding cores can be found in the CH patent applications 00 860 / 87-5, 1 788 / 86-0 and 2 267 / 84-6 . The winding modules are arranged one behind the other in the conveying direction so that the winding planes, ie the center planes of the windings of the individual winding stations 8 perpendicular to the winding axis, are perpendicular and in one plane. The feed belt is carried out in a straight line over the winding modules 41-43. In a similar manner, the discharge belt 12 lies below the winding modules, parallel to the Feed belt and the winding levels. Of course, the arrangement of the infeed and outfeed belt can be interchanged or slightly shifted laterally with respect to the winding modules. In addition, the individual winding stations can also be offset laterally for special applications, the feed and discharge having corresponding switches or connecting conveyor sections to overcome the lateral offset.

It is easy to see that the device can contain other types of conveying means, for example a clip conveyor, a tape conveyor or a clip chain system, instead of a feed or discharge belt. Different conveying means can be used for the connecting sections between the switches 51, 52, 53 to the individual winding modules 41, 42, 43.

All conveyor lines and winding modules are therefore aligned parallel to a vertical plane. This arrangement of the winding modules or the conveyor belts has the great advantage that all the winding stations 41-43 or the windings held on their winding brackets 46-48 can be easily reached from at least one side, so that the windings or winding cores, for example, with one Floor conveyor, which can travel back and forth along the arrangement in a path that is also parallel to this plane, can be gripped and exchanged. This simple handling option enables the use of special, for example inductively controlled, handling devices. Due to the interchangeability of the rolls, any quantity of printed products can be buffered in a space-saving and cost-effective manner in a separate warehouse. Since it is necessary to replace the windings very frequently in the case of high working capacities, at least three winding modules are generally required. As can be seen from the drawing, in this exemplary embodiment, those in the description of the method according to the invention fall mentioned inputs 21-25 and outputs 31-35 together, ie the windings are inserted at the same location of the winding module and removed again.

A second conveyor connection 66, 67, 68 with a 180 'deflection leads from each winding module to the common discharge belt 12. As can be easily seen, the products obtained via the feed 11 are turned by winding and unwinding in a winding module, i.e. their orientation o changed. In this exemplary embodiment, all winding modules 41-43 are the same and correspond to the type 2 mentioned above. If the unwinding speed of the individual winding modules is controllable, a desired clock frequency can also be achieved at the output 3, given the corresponding speed of the discharge belt 12.

A further exemplary embodiment of the invention is shown in FIG. The common feed belt 11, the common discharge belt 12, switch devices 51-53 and three winding modules 41-43 can again be seen. Each winding module here contains a winding station 8 and a wrapping device 7. The manner of wrapping is described, for example, in Swiss Patent 657,115. Turnouts 74-76 connect the main winding 8 to the feed belt 11 on the one hand and to the wrapping device 7 on the other hand. The wrapped printed products can be brought from a wrapping device to the discharge belt 12 by a second group of turnout devices 56, 57, 58. As can easily be seen, the printed products here maintain their orientation as well as their mutual position between input 2 and output 3. These are type 3 or 8 winding modules.

In order to also be able to achieve a change in the orientation of the printed products with these winding modules, it is possible, for example, to provide an additional switching device at the winding station 8, which connects the winding station 8 directly to the discharge belt 12, or a direct switch can also be used Connection from the feed belt 11 to the individual winding devices 7 can be provided.

FIG. 4 shows an arrangement with two winding modules 41, 42 of type 2 or 6 and two winding modules 43, 44 of type 8. In addition to the winding device 7, the winding modules 41, 42 have a deflection device 79 which turns the printed products through 180 °, ie whose orientation o changes. By means of an associated switch 78, either the winding device 7 or the deflection device 79 of these winding stations can be activated. Accordingly, the printed products supplied via the conveyor connection 61, 62 are fed to the discharge belt 12 in an unchanged manner or turned through 180 °, depending on the position of the switches 78. If the products are to be fed to output 3 unchanged, they can be buffered by switching the switches 51-54 via any of the winding modules 41-44. On the other hand, should the orientation of the printed products be changed, i.e. the parameter o are converted, the winding modules 41 and 42 are preferably used. It is of course also possible to carry out buffering via the winding modules 43 and 44 and to carry out the conversion in a second work step using module 41 or 42.

In order to be able to control the rotational speed of the winding during unwinding (change of the clock frequency t 1 to t 2), the drive must be variable in speed. For example, a reversible, pole-changing asynchronous motor is used.

The switch devices 51-60, 71, 72, 79, etc. are sufficiently known from the prior art and can be implemented, for example, by means of short, pivotable conveyor belt sections.

FIG. 5 shows another possible application of the method according to the invention. The basic diagram and the reference numbers correspond to FIG. 1. A buffer clock 77, as is known, for example, from Swiss Patent 610 276, is present in the area of the output 3. This makes it possible to discharge products 41-45 simultaneously from the connection 5 and / or from different winding modules. The corresponding product flows are "spliced together" by means of the buffer clock 77, i.e. added to a single stream and fed to the output 3. In addition, at least one return path 80 is provided after output 3 to input 2. As shown, this return 80 can start after a first machine module 81, which represents a processing step of the products. In an analogous manner, a return 80 'to the input 2 can be provided after each further machine module. The result of this is that if any machine module fails, the products can be returned to input 2 and, accordingly, only one buffer arrangement 1 must be provided within an overall system. A device for carrying out this method can be achieved in a simple manner in that the returns, similar to the conveyor lines 61-63 in FIG. 2, are returned to the feed belt from above.
