Abstract

Material to be removed from winding stations (full rolls from unwinding stations, winding cores from unwinding stations) is deposited by a manipulating/transport means onto a handling device (20.1) and from there transported by a manipulating/transport vehicle (30) to a storage area. Material to be fed in at winding stations (empty winding cores for a winding station, full rolls for an unwinding station) are transported by the same manipulating/transport vehicle (30) from a storage area to the handling device, and deposited there, so that they can be fed to the winding station by the manipulating/transport means. The handling device (20.1) is designed in such a way that the manipulating/transport vehicle (30) can deposit the material to be fed and take hold of the material to be removed from a single position. The manipulating tool only has to execute a single translatory movement between the two operations. In the preferred variant of the method, a fork lift truck is used as a manipulating/transport vehicle (30), and in each case two rolls lying on a pallet (40) and in each case two winding cores lying on a pallet are stored as storage units. A storage unit of this type is transported to the handling device (20.1), the storage unit being rotated through +/- 90 DEG and deposited there without a pallet (40). The pallet is moved by the forks of the fork lift truck to the material, to be removed, in the handling device and transported away from the latter together with the material to be removed, the forks being once again rotated through +/- 90 DEG and stored, together with the material to be removed, as a storage unit. <IMAGE>

Description

The invention is in the field of further processing of printed products and relates to a method and a device according to the preambles of the corresponding independent claims. The method and device are used for changing, handling and intermediate storage of printed product windings.

It corresponds to the state of the art to guide printed products, preferably folded printed products, which are laid out by any processing step, for example a rotary press in scale formation and which are to be temporarily stored before the next following processing step, to a winding station (with a winding function) where they are be wound onto a winding core with the aid of a winding tape. Wraps produced in this way are stored upright or horizontally with or without storage aids, such as pallets, and, if necessary, fed back to a winding station (with an unwinding function), unwound there and fed back in a scale formation for further processing.

Winding stations for winding or unwinding printed products in scale formation are described, for example, in European Patent Nos. 161569, 0230677 and 281790 (US Pat. Nos. 4601436, 4769973 and 4898336) by the same applicant or in publications EP-447903 (US-5158242) or US 5176333 by the same applicant. These stations are designed in such a way that they always process (rewind or unwind) one reel while a second reel is being changed. Manipulation and transport mix the winding station and warehouse, through which the goods to be removed (full winding from winding stations, empty winding cores from unwinding stations) are brought from the winding station to the warehouse and the goods to be used (empty winding cores for winding stations, full winding for unwinding stations) are brought from the warehouse to the winding station is carried out with the help of various aids and processes and requires either complex devices or complicated maneuvers and manual labor.

For example, mobile cassettes are used which contain the winding core and winding tape and which are transported between the winding station and the warehouse with the aid of a storage vehicle. Such cassettes are described, for example, in the patents CH-652699 or EP-243837 by the same applicant. The cassettes serve as movable devices as part of the winding station, as well as a transport device and as a storage device. For the change, a cassette must be positioned exactly at the winding station and then serves as part of the winding station. Cassettes with goods to be removed or goods to be inserted are transported to or from the warehouse by a transport vehicle and are stored or removed. Such a method requires a cassette for each winding or winding core to be stored and a comparatively large storage space for each cassette. However, no special requirements have to be made with regard to equipment and shape at the storage location and the entire storage facility can also be composed of any free spaces that are large enough for a cassette. The procedure also requires in the area of Wrapping stations take up a lot of space, since at least two cassettes must always be deposited there when the cassette is changed (see also description of Figure 2) and the vehicle must maneuver there with the cassettes. The working process with cassettes is not only complex but also hardly automatable, but it has the advantage that no specially equipped storage space has to be available and that only one means of transport has to be used between the winding station and the storage, which means that the one to be used and the one to be removed Well, it doesn't have to be "transhipped" from one means of transport to another.

In order to simplify such complicated work steps and make them accessible to automation, winding change and storage processes have been developed in which the goods to be removed are removed from the winding station by a manipulation / transport means and deposited on a stationary handling device, where they are deposited by one, for example on a Rail moving shuttle vehicle is picked up. The goods to be used are brought from the same shuttle vehicle to the stationary handling device and deposited there, from where they can be used by the manipulation / transport means on the winding station. An automated overhead crane is usually used as the manipulation / transport means. If the handling device and the shuttle vehicle are designed accordingly, the goods to be used can be deposited and the goods to be removed can be deposited with only two positioning steps of the vehicle. Such methods and devices are described, for example, in publication EP 505320 by the same applicant and in German Offenlegungsschrift No. 3602320 (Grapha-Holding AG).

Processes with stationary handling devices, manipulation / transport means mix winding station and handling device and shuttle vehicles between handling device and warehouse, which are on a rail can move several winding stations while moving, save a lot of transport, many maneuvers and many manipulation movements compared to the above-mentioned methods with cassettes and can be automated more easily. But they are more complex in terms of the necessary devices and especially in relation to the storage space. The warehouse must either be equipped with storage devices similar to the transhipment devices, i.e. it cannot be composed of various more randomly available places, and it must be accessible to the shuttle vehicle, i.e. as close as possible and accessible from a rail (DE-3602320 ). Or the goods to be removed and the goods to be used must be handed over to another storage vehicle or storage tool for storage in a further transhipment point (EP-505320).

The object of the invention is to demonstrate a method with which the advantages of the above-mentioned methods for changing and temporarily storing printed product windings can be combined, the disadvantages being eliminated as far as possible. According to the method according to the invention, which should also be applicable for winding and unwinding stations, winding changes and intermediate storage should be carried out with a minimum of transport, maneuvering and manipulation movements. According to the method according to the invention, full windings and empty winding cores are to be manipulated in the same way and without manual help, and it should be possible to store windings and cores with a handling maneuver at a storage location that has no requirements with regard to location and equipment in relation to Size minimum requirements must be made. Since the process should offer the greatest freedom in terms of storage space, the process should be less automated and still be able to be carried out with a minimum of personnel and vehicles.

The invention also makes it its task to provide a handling device for carrying out the method according to the invention, with which printed product rolls and winding cores can be provided between the winding station and the warehouse in a manipulation-appropriate manner for both a winding-side and a storage-side manipulation / transport means. The handling device should be simple, inexpensive to manufacture and space-saving.

This object is achieved by the method and the device according to the characterizing parts of the corresponding independent claims.

The central idea of the invention is to create a stationary handling device which is assigned to at least one winding station and on the winding station which is full for the winding station (good to be removed) from the station and empty cores (good to be used) from a store, in the case an unwinding station, empty cores (goods to be removed) from the station and full rolls (goods to be used) can be deposited from a warehouse in such a way that an essentially commercial manipulation / transport vehicle that brings the goods to be used from a warehouse is located in the area of the handling device only has to be positioned exactly once in order to exchange the good to be used for the good to be removed with a single translatory, preferably rectilinear movement of its manipulation tool. The manipulation / transport vehicle can be, for example, a commercially available forklift truck, the forks of which can be moved against one another / apart from one another for gripping / releasing and at least in the vertical direction for the manipulation.

The loading of the handling device with material to be removed from the winding station and the loading of the winding station with the material to be inserted of the handling device is carried out, for example, with the aid of an overhead crane and can be fully automated. In contrast, the manipulation / transport vehicle, with which the goods to be used are brought to the handling device and the goods to be removed are brought away from the handling device, is operated manually. In this way, the manipulation / transport vehicle can drive to any available storage space in order to deposit or take a load.

The method according to the invention thus combines the advantage of a simple change in accordance with the storage method with a shuttle vehicle with the advantage of a storage location that is not specially equipped and not specifically located according to the storage method with cassettes. The method according to the invention can carry out winding changes and storage with only one handling maneuver, but can also be combined with more complex, for example fully automated, storage methods by means of a further handling maneuver. The space required in the area of the winding stations is minimal.

The handling device according to the invention essentially consists of a frame with a space for at least one full roll and at least one empty roll core. The two places are arranged in such a way that they can be reached on the one hand (on the winding station side) from the overhead crane of the winding station and on the other hand (on the storage side) from the manipulation tool of the manipulation / transport vehicle, namely from one and the same position of this vehicle. The two places are arranged in such a way that the manipulation tool of the manipulation / transport vehicle only has to be moved in one direction if possible between the depositing of the goods to be used and the gripping of the goods to be removed.

FIG. 1 shows very schematically a general method for changing, handling and temporarily storing printed product windings W and winding cores WK with a winding station AUF, into which a shingled stream ST enters, and an unwinding station AB, from which a shingled stream ST runs out. Both winding stations have winding positions A and B for two windings, one of which is unwound or wound up (position A in the figure), while the other (position B in the figure) is changed. In the winding station in position B, a full printed product roll W (good to be removed) is exchanged for an empty roll core WK (good to be used), in the unwinding station AB an empty roll core WK (good to be removed) for a full roll W (good to be used). The goods to be removed are transported from the winding station UP or DOWN to a storage facility L and stored there, the goods to be used are removed from storage facility L and transported to the winding station UP or DOWN. Between the winding station and the warehouse, advantageously closer to the winding station, there is at least one transfer location UM assigned to one or more winding stations, on which the goods to be used as well as the goods to be removed are temporarily deposited. Manipulation and transport of the windings and the winding cores between the winding station and the transfer point are advantageously carried out by a fully automated manipulation / transport means, for example, an overhead crane. Manipulation and transport of coils and winding cores between the transhipment point and the warehouse can be carried out by any other manipulation / transport means, advantageously a manipulation / transport vehicle, and a further transhipment point and a third manipulation / transport means can also be activated.

Figure 2 now shows schematically the workflow between the winding station and storage for a method according to the prior art, which works with cassettes. Field 1 represents any storage location. Field 2 represents a precisely defined loading / unloading location on which the cassette is positioned and on which it serves as part of the winding station, by winding a winding directly on the cassette or unwound from the cassette becomes. Field 3 represents a first and field 4 a second parking space in the area of the winding station.

The workflow for a transport vehicle to transport the cassettes, with which empty trips to the warehouse are to be spared as far as possible, is as follows: a: Transport and deposit the first cassette (with a full reel for the unwinding station, empty for the rewinding station) from the warehouse to parking space 3; b: drive to the loading / unloading station, position the vehicle and take the second cassette; c: transport and deposit second cassette to parking space 4; d: drive to parking space 3, position the vehicle and take the first cassette; e: Transport the first cassette to the loading / unloading station 2, position the vehicle and position the cassette; f: drive to parking space 4, position the vehicle and take the second cassette; g: Transport the second cassette to the storage location. Under certain circumstances, the appropriate cassette can be used to manually remove the second cassette from the loading / unloading station and to position the first cassette there, which simplifies the workflow of the vehicle, but requires more personnel.

A process with cassettes which is simpler and simpler in terms of apparatus, but still significantly more complex, is described in European Patent 0242607 by the same applicant. The loading / unloading station is designed for two cassettes and the fully loaded / unloaded cassette is automatically moved from the first to the second place, where it can be picked up by the transport vehicle after it has positioned and deposited the replacement cassette in the first place.

Figure 3 now shows the corresponding workflow according to the inventive method. Field 5 again represents an arbitrary storage location, field 6 a transfer location which is equipped with a stationary transfer device according to the invention, and field 7 a winding station. The workflow is as follows: h: transport the goods to be used with manipulation / transport vehicle from storage area 5 to handling area 6, position the vehicle precisely, deposit the goods to be used on handling equipment; i: Move the manipulation tool of the manipulation / transport vehicle in one direction, grasp the goods to be removed and transport them to the warehouse. Transport and manipulation between the winding station 7 and the handling area 6 is carried out fully automatically by, for example, a traveling crane.

A comparison of the two FIGS. 2 and 3 shows the obvious advantages of the method according to the invention with a stationary handling device compared to the method according to the prior art with cassettes. Another advantage, which cannot be seen from the figures, is that a smaller manipulation / transport vehicle, such as, for example, is used to transport the windings or winding cores according to the method according to the invention a forklift is sufficient, while a larger vehicle is required for the significantly heavier cassettes.

FIGS. 4 and 5 show winding stations UP and DOWN with an overhead crane 10.1 or 10.2 for changing windings and winding cores and an exemplary embodiment of the handling device 20.1 or 20.2 according to the invention, on the windings W and winding cores WK, each on a winding space 21 and a core space 22 can be deposited. The handling devices are advantageously arranged in such a way that the windings deposited thereon are essentially parallel to the windings on the winding station. In the embodiment shown, two windings W or two cores WK can be deposited on the handling device in each case on a corresponding winding space 21 and a core space 22. Embodiments with winding and core positions, on which only one winding and one core or more than two windings and an equal number of cores can be deposited, are quite conceivable.

The deposited rolls have essentially the same spatial position as the rolls on the winding station, that is to say their axes of rotation are essentially horizontal. Several windings are deposited close to each other on the winding station in such a way that their axes of rotation run in the same vertical plane. The deposited cores also have essentially the same spatial position on the core site as on the winding station (horizontal axis of rotation) and, in the case of several cores, they are arranged one behind the other in the transport direction on an inclined plane, in such a way that their order is automatically adjusted by gravity and it is removed from the Manipulation tool of the manipulation / transport vehicle can be safely gripped or delivered.

Figure 4 shows the case of the winding station AUF. The overhead crane 10.1 removes one full roll W after the other from the winding station and deposits it in the winding station 21 of the handling device 20.1 by gripping the rolls in the inner region of the winding core. The winding station is equipped with at least one pair of wedges 23 and a lateral support 24 in such a way that the two windings W can be positioned precisely thereon, leaning slightly against the lateral support 24 (see also FIGS. 10 and 11). The core station 22 is equipped with a core guide 25 which protrudes against the winding station, is provided on the winding station side and on the bearing side with a stop, which is inclined against the winding station and on which winding cores deposited in the core station 22 roll against the stop on the winding station side, from where they are individually carried by the overhead crane 10.1 can be taken and brought to the winding station. The figure shows two winding cores on the core station 22 and a core shown in dashed lines, which is rolled against the winding station and is now at the winding station-side stop of the core guide 25 and can be gripped in this position by the overhead crane 10.1.

FIG. 5 shows an unwinding station AB with an overhead crane 10.2, which corresponds to the overhead crane of FIG. 4, and a handling device 20.2 according to the invention. The overhead crane here removes individual winding cores WK from the unwinding station and deposits them (core shown in dashed lines) on the part of the core guide 25 protruding on the winding station side, which in this case is arranged sinking against the core space 22, so that the cores deposited on the core guide enter the core space 22 roll and stand at their bearing-side stop. The two winding cores shown in solid lines thus assume a position in which they can be securely gripped by the manipulation tool of the manipulation / transport vehicle. The overhead crane also serves to bring windings from the handling device 20.2 to the unwinding station.

FIGS. 6 and 7 show in detail the working method already generally described in connection with FIG. 3 on the storage side of the handling device according to the invention, that is to say the cooperation between handling device 20.1 or 20.2 according to the invention and manipulation / transport vehicle 30, specifically for a winding station (FIG. 6) and for an unwinding station (Figure 7). Both figures are shown as six successive relative positions of manipulation / transport vehicle 30 and transshipment device 20.1 and 20.2 shown one below the other. The method variant shown and the corresponding embodiment of the handling device according to the invention relate, like FIGS. 4 and 5, to the manipulation of two windings W and two winding cores WK.

The manipulation / transport vehicle 30 is a commercially available forklift truck, the manipulation tools of which are, for example, two forks 31 that can be moved relative to one another and that are arranged next to one another and movable in the horizontal direction relative to one another for the embodiment shown. Furthermore, the entire manipulation tool (both Gabein with each other) can be moved at least in the vertical direction.

The handling device 20.1 or 20.2 corresponds to the handling device of FIGS. 4 and 5. Winding station 21 and core station 22 are freely accessible on all sides and are arranged exactly vertically one above the other.

The uppermost illustration shows the manipulation / transport vehicle 30, which transports the goods to be used against the handling device 20.1 or 20.2. It approaches it from the side opposite the winding station. Depending on the type of goods to be used (winding cores WK or winding W), the forks are at the level of the winding space 21 or the core space 22 aligned the handling device. Winding or winding cores are held by the forks in the mutual position that they should also take on the handling device, that is, two windings with horizontal axes of rotation lying in a vertical plane or two winding cores arranged one behind the other in the direction of transport with parallel, horizontal axes of rotation .

The second representation shows the entry of the goods to be used into the corresponding place of the handling device. For this purpose, the manipulation / transport vehicle is aligned as precisely as possible laterally on the handling device when starting off. If the manipulation tool (both forks together) can also be moved in the horizontal direction, the lateral position can be finely adjusted by moving the manipulation tool sideways. The height is set by vertical movement of the manipulation tool, for windings somewhat higher than the definitive deposit position, since the wedge pairs 23 first have to be passed over and only then can the windings be lowered into the definitive deposit position.

The third illustration shows the depositing of the goods to be used. For this purpose, the forks are moved apart and let go of the winding or winding cores. The winding cores roll immediately on the core guide 25 against the winding station. The windings stand on the wedge pairs 23 and lean against the lateral support 24.

The fourth representation shows the vertical movement of the manipulation tool in FIG. 6 upwards, in FIG. 7 downwards, which is the only maneuver that is necessary between depositing the goods to be used and detecting the goods to be removed.

The fifth illustration shows the detection of the goods to be removed. FIG. 7 shows that the two winding cores to be removed are deposited in the core space 22 by means of a corresponding design of the core guide 25 in such a way that they can be securely gripped by the forks.

The sixth and last illustration shows the manipulation / transport vehicle moving away with the goods to be removed.

The shape of the Gabein 31 from standard forklift trucks is standardized and corresponds to the shape of standardized pallets. It is now a particularly advantageous method variant of the method according to the invention if the forklift carries a pallet on one fork while it carries out the workflow shown in FIGS. 6 and 7. Such a standardized European pallet 40 is shown in dashed lines on the fork facing away from the viewer. The lateral support 24 is also designed in such a way that the pallet 40 does not come into conflict with it when retracting coils (FIG. 7, second illustration).

FIGS. 8 and 9 show exemplary bearings of printed product coils (FIG. 8) or winding cores (FIG. 9), which can be created with the method variant with pallets. For example, two windings W or two winding cores WK are always stored per pallet 40. Such storage units can be stacked on top of one another. If such a bearing is to be created, the manipulation tool of the manipulation / transport vehicle must also be rotatable, in both directions by at least 90 °. This means that the manipulation / transport vehicle necessary for this method variant is advantageously equipped with a manipulation tool that can clamp an object that can be moved in the horizontal and vertical direction and that can be rotated in at least 90 ° in two directions, Requirements that are met by many commercially available forklift trucks and corresponding attachments.

FIGS. 6 to 9 illustrate the central advantages of the method according to the invention, in particular the method variant with a pallet. The goods to be used are lifted in the warehouse in the form of a storage unit with the pallet 40, transported to the handling device, where they are moved and deposited in the appropriate place, being clamped somewhere between the storage device and handling device and rotated by 90 °. The manipulation tool with the pallet moves after positioning the goods to be inserted in only one direction to the place of the goods to be removed and grips them. The goods to be removed are then transported to the warehouse and placed there, where they are rotated somewhere between the handling device and the warehouse by 90 ° in such a way that the pallet comes to lie down. Since every pallet freed from the goods to be used is immediately used for the goods to be removed, no pallet has to be deposited in the area of the handling device. Since the storage units (pallet plus winding or cores) have sufficient storage stability, no requirements with regard to equipment have to be made to the storage location. Any free space can be used as a storage space.

Of course, other storage methods are also possible. For example, the windings can also be stored standing against one another, a storage method that then does not require pallets and for which the rotary movement of the manipulation tool is not necessary.

The handling device according to the invention and a forklift can also be used for the storage method described in EP-A-505380 the same applicant is described, can be used between the winding station and warehouse instead of the handling device and shuttle vehicle described there. However, the forklift truck must then deposit or receive the reels and the winding cores in front of the warehouse at another transshipment point, where they can be picked up or deposited by a special storage tool. In this case too, there is no need to carry pallets.

FIGS. 10 and 11 show in detail an exemplary embodiment of the handling device according to the invention, on the right each as a side view as in FIGS. 4 to 7, on the left as a front view from the storage side on which it is approached by the manipulation / transport vehicle. Figure 10 shows the embodiment for cooperation with a winding station, Figure 11 shows the embodiment for cooperation with a winding station. In both side views, the manipulation / transport vehicle is also partially visible, which has just retracted winding cores in FIG. 10 and captures winding cores for transport away in FIG. 11.

The two front views clearly show how the windings W and the winding cores WK are deposited on the winding space 21 and the core space 22 of the handling device 20.1 and 20.2, respectively. It can be seen from these front views that only one or more than two windings can be deposited in the same way. The same applies to the winding cores. A winding core would be arranged in the center of the pallet 40 by appropriate design of the core guide 25, four cores were arranged two next to each other in the manner shown. According to the method described so far, the cores are arranged centrally under the windings and not on the side support 24 side, as shown in FIGS. 10 and 11. Only with a central arrangement of the cores can a forklift be used, the forks of which move symmetrically against each other. A side arrangement As shown in FIGS. 10 and 11, a forklift with a quasi-stationary fork and a fork that is movable against it requires a variant that is not commercially available but can simply be produced from a commercially available forklift. Only with such asymmetrically movable forks can the method according to the invention be carried out with asymmetrically deposited cores without the cores being pushed into the middle when they are gripped. Viewed from the storage side, the cores can either be deposited on the right, as shown, or deposited on the left. If a forklift is to be able to operate handling stations with cores deposited on the right and left, it must be able to turn its manipulation tool in both directions so that the pallet that has to be carried on the quasi-stationary fork always lies down for storage.

In the side views of FIGS. 10 and 11, a pivot lever 26, an upper pivot angle 27 (FIG. 10) and a lower pivot angle 28 (FIG. 11) are visible as further details. The swivel lever 26 is arranged on the side support 24 so that it can be swiveled about a swivel axis M such that it is swiveled upwards (extended position) when retracting wraps with a pallet, and swivels downwards when the manipulation tool is moved down with the pallet (dashed position) and takes over such a part of the lateral support function without coming into conflict with the retracting fork or the pallet.

The upper swivel angle 27 is attached at its kink point about a swivel axis N to the handling device 20.1 in the area of the core space in such a way that it can prevent the cores from rolling away immediately when they are released from the grip of the forks. Such an upper pivot angle 27 is only useful on a handling device 20.1 which is assigned to a winding station (FIG. 10). Its function is as follows: without cores, the upper swivel angle 27 swivels through the Gravity into a position in which its leg 27.1 on the winding station side is directed downwards, while its leg 27.2 on the bearing side bears against the handling device in a substantially horizontal position (dash-dotted position). The core guide 25 is inclined towards the winding station. If the cores are now retracted, they move the upper swivel angle 27 such that the leg 27.1 on the winding station finally assumes an essentially horizontal position and the leg 27.2 on the bearing side is directed towards the bottom (extended position). The two legs of the upper swivel angle 27 are shaped such that they prevent the two cores from rolling away in this position. The upper pivot angle 27 is locked in this position. If the cores are then used for the winding station, the locking is released, whereby the cores roll away against the winding station (dash-dotted position of a core) and the upper swivel angle 27 swings back into its rest position.

The lower pivot angle 28 serves as a bearing-side stop for the core guide 25 when it is inclined against the bearing side (for unwinding station). It prevents cores that roll into the core space from rolling away against the manipulation / transport vehicle, but must be able to be swiveled away to transport the cores away. A lower pivot angle 28 makes sense in a handling device 20.2 which is assigned to an unwinding station (FIG. 11). The lower pivot angle 28 has a leg 28.1 on the winding station side and a leg 28.2 on the bearing side. Between the legs, it is pivotable about a pivot axis Q in the lower region of the core space in such a way that in its one pivot position (extended position) the leg 28.2 on the bearing side can stop 25 cores that are rolling on the core guide rising against the winding station and that it is in its other pivot position (dashed position) does not hinder the extension of the cores. The lower swivel angle 28 can be locked in its stopping position as long as cores are deposited on the core guide by the overhead crane. The lock is released when those deposited in the core square Cores are gripped by a manipulation tool and are to be extended.

The cores are guided laterally in that the core guide 25 has a central slot 29 in which the winding tape WB, which is rolled up centrally on the core, runs.

In all figures, the handling device according to the invention is shown with the winding area at the top and the core space at the bottom. It is also conceivable that the core place is on top, the changing place is on the bottom.

Method for changing, transloading and intermediately storing printed product rolls (W), in which with at least one manipulation/transportation means (10,1, 10.2) for a winding on station (AUF) full rolls to be removed are removed from the station and brought to a storage location (L) and empty roll cores (WK) to be inserted are brought from a storage location (L) and inserted on the station, or for a winding off station empty winding cores (WK) (material to be removed) are removed from the station and brought to a storage location (L) and a full roll (W) to be inserted is brought from a storage location (L) and inserted at the station, characterized in that a winding station-side manipulation/transportation means (10.1, 10.2) removes the material to be removed individually from the winding station (AUF, AB) and deposits it on a stationary transloading apparatus (20.1, 20.2) and fetches the material to be inserted individually from the transloading apparatus (20.1, 20.2) and inserts it on the winding station (AUF, AB), the winding cores (WK) and rolls (W) maintaining the horizontal position of their rotation axes and in which in each case a winding station-side manipulation/transportation means (10.1, 10.2) for a stationary transloading apparatus (20,1, 20.2) is associated with at least one winding station (AUF, AB) and the material to be inserted is deposited by a manipulation/transportation vehicle (30) with a manipulating tool (31) in the function of a store-side manipulation/transportation means on the transloading apparatus (20.1, 20.2) and the material to be removed is gripped and transported away by the same manipulation/transportation vehicle (30) with the same manipulating tool (31) on the transloading apparatus (20.1, 20.2), the material to be inserted or removed being gripped or deposited by a moving towards or away from one another by two tool parts of the manipulating tool (31) and in which between the depositing of the material to be inserted and the gripping of the material to be removed the manipulating tool (31) as a whole performs a single vertical movement.
2. Method according to claim 1, characterized in that the manipulation/transportation vehicle (30) with manipulating tool (31) manipulates and transports at least one printed product roll (W) or an equal number of empty winding cores (WK).
3. Method according to claim 2, characterized in that the manipulation/transportation vehicle (30) is a fork lift with a manipulating tool (31) in the form of a fork pair.
4. Method according to claim 3, characterized in that the material to be inserted is deposited or the material to be removed gripped, in that the forks are moved symmetrically apart or against one another.
5. Method according to claim 3, characterized in that the material to be inserted is deposited or the material to be removed gripped, in that one fork remains quasi-stationary and the other fork is moved relative to the quasi-stationary fork.
6. Method according to one of the claims 3 to 5, characterized in that the fork lift, when working on the transloading apparatus, jointly moves a pallet (40) on one fork, so that the material to be inserted and removed is transported and stored together with the pallet (40).
7. Method according to claim 6, characterized in that in each case a number of rolls (W) resting on a pallet (40) and the sane number of winding cores (WK) resting on a pallet (40) are stored as storage units at random storage locations (L), that such a storage unit is transported by the fork lift to the transloading apparatus (20.1, 20.2), it being rotated by 90° that the storage unit is deposited on the transloading apparatus (20.1, 20.2) without the pallet on a location for the material to be inserted, that the pallet by a vertical movement of the forks is moved into the vicinity of the material to be removed, that the material to be removed is gripped and transported to a storage location (L), where it is rotated by 90°, and that the material to be removed is deposited with the pallet in the store.
8. Method according to one of the claims 1 to 5, characterized in that the material to be inserted is gripped by the manipulation/transportation vehicle (30) at a further transloading location and the material to be removed is deposited by the manipulation/transportation vehicle (30) at the same, further transloading location and that for the placing in and out of store of the rolls (W) and winding cores (WK) a further manipulation/transportation means is used.
9. Stationary transloading apparatus (20.1, 20.2) for transloading printed product rolls and winding cores with a manipulating tool (31) in the method according to any one of the claims 1 to 8, characterized in that it has in a frame too vertically superimposed locations (21, 22) accessible from two sides and from which one is equipped as a roll location (21) with securing means for securing at least one roll with a horizontal roll axis and the other is equipped as a core location (22) with guidance and securing means for guiding and securing the same number of winding cores with horizontal axes.
10. Transloading apparatus according to claim 9, characterized in that the securing means of the roll location (21) and the guidance and securing means of the core location (22) are so arranged that one front side of the number of deposited rolls is located in substantially the same plane as one front side of the deposited winding cores.
11. Transloading apparatus according to claim 9, characterized in that the securing means of the roll location (21) and the guidance and securing means of the core location (22) are so arranged that the substantially vertical plane of symmetry of the number of deposited rolls and the vertical plane of symmetry of the deposited winding cores coincide.
12. Transloading apparatus according to one of the claims 9 to 11, characterized in that the securing means of the roll location (21) have at least one pair of wedges (23), a lateral support (24) and a swivel lever (26).
13. Transloading apparatus according to one of the claims 9 to 11, characterized in that the guidance and securing means of the core location (22) have on the winding station side a core guide (25) projecting from the apparatus.
