Description

The invention relates to a roll changer with safety device according to the preamble of claim 1 and to a method for using a roll changer with safety device according to the features of claim 13.

By the DE 10 2007 025 800 A1 a danger area safeguarding a reel changer is known, with a security area for the automatic reel placement of the reel splitter extends on a receiving and / or delivery side over the entire width to the frontal side frames, and which on the one hand by the roll changer and by one or more adjoining units or mechanical shut-off devices and by one or two sensory monitored accesses against unnoticed entry is essentially limited.

From the WO 2005/080241 A2 It is known to provide a security area for the reliability in the environment of large moving material rolls. Here, the attachment of a fence is proposed at the boundaries of a roll of material storage. For introducing or removing material rolls into the bearing, a lock may be provided in the area protection. In the lock area, a preferably non-contact area security is proposed, which can be realized for example via light barriers or ultrasonic sensors. The security area has an interim storage.

The EP 1 986 942 A1 and the WO 2007/096007 A1 relates, for example, to a roll changer with a roller grille for safeguarding the operating personnel in the event of a shell bursting during the operation of the printing press. On a side frame of the Reel changer is a control panel for the reel changer recognizable. The control panel on the side frame of the reel changer shows, for example, the EP 1 644 191 B1 ,

By the EP 1 892 207 A2 and the DE 10 2006 040 140 A1 a method is known in which a roller arranged on a first transport means can be pivoted by means of a device through 180 ° about a vertical axis, while the roller and the first transport means is located on a second transport means with suitable device. The role and the first means of transport can be supplied to or removed from storage bins.

By the DE 10 2005 048 466 A1 a reel changer with safety device is known, wherein adjacent to the reel changer a delimited from an environment safety zone is formed, which is bounded by a protective cover and a catching device, wherein a roller is arranged on a means of transport and the catching device is partially movable with a means of transport.

By the DE 10 2005 032 600 A1 a reel changer is known, wherein a roller is arranged on a first transport means, which is arranged on a second, arranged in the security area transport means.

By the DE 10 2006 019 595 B3 For example, a roll exchanger with a security area is known, wherein the security area is designed with tread mats, which can detect a person or objects arranged thereupon.

By the WO 2009/050332 A1 a reel changer with safety device is known, which has a receiving and / or delivery area and adjacent to which is defined by an environment defined by at least one access security area, wherein the reel changer has a security zone, the receiving and / or delivery area includes and the means at least one movably arranged first protective cover is separated from the safety area and / or separable, and wherein the at least one first protective cover is an opening of the safety zone to the safety area at least partially occlusive and / or closable.

The invention has for its object to provide a reel changer with safety device and a method for using a reel changer with safety device.

The object is achieved by the features of claim 1 and the features of claim 13.

With a reel changer with safety device, wherein the reel changer has a receiving and / or delivery area and adjacent to the reel changer one of an environment by the reel changer and / or at least one unit and / or at least one shut-off device delimited by at least one preferably sensory monitored Access and preferably exclusively by the at least one access enterable security area is formed, wherein the roll changer has a security zone that includes the receiving and / or delivery area and which is separated and / or separable by means of at least one movably arranged first protective cover of the security area and / or the at least one first protective cover is an opening of the security zone towards the security area, at least partially and preferably completely occlusive and / or closable, and wherein the opening preferably is parallel to one he rotation axis of arranged on support arms of the reel changer receiving devices for rolls extends, in particular to achieve the advantage that by training the security zone operators are protected from fragments of ruptured roles and that by the delimited or demarcated security area independent of possible role changes accessible yet protected environment is created in the further steps can be performed in parallel to the role change. In this case, a design effort is minimized by the safety zone has a single opening, which makes other openings unnecessary.

Another advantage is that each roller remains arranged on a first means of transport and thereby possible damage to the rollers, for example, during handovers are avoided.

Another advantage of an embodiment in which at least one, at least a first Transport means and / or at least one residual roll and / or residual sleeve container transportable second transport means is arranged is that this at least one second transport means is versatile and thereby the smallest possible number of means of transport is sufficient.

Another advantage of an embodiment in which the at least one access is sensory-controlled access is that operators are prevented from entering a danger area as long as there is acute danger. Further advantages result if the at least one sensorically monitored access has a non-contact protective device which has a light grid with at least two light beams and preferably the at least two light beams lie in a plane which includes a tilt angle φ with a vertically arranged plane which intervenes 8 ° and 25 °, by creating an intelligent monitoring system that makes operation even safer.

A further advantage of an embodiment in which the security area has an intermediate storage for at least one roller arranged on at least one first transport means, and wherein the intermediate storage has at least one storage location different from the at least one second transport means, apart from at least one feed track and / or at least one discharge track, in which the at least one arranged on the at least one first transport means role is storable, is that the security area can be used effectively, since especially in storage areas dangers can arise by transporting heavy roles. In particular if the intermediate storage has at least one transfer position assigned to at least one storage position and the at least one second transport means is arranged or arrangeable in the at least one transfer position and a first transport means with or without a roller between the second transport means arranged in the at least transfer position and in each case at least a storage position of the intermediate storage is interchangeable, there is the advantage that a particularly effective storage system is created. This is reinforced by the fact that preferably at least a first transport means can be arranged on the at least one second transport means. Another advantage is that the intermediate storage can be used flexibly by arranging a plurality of storage positions, in particular for the storage of one or preferably a plurality of rollers, the introduction of new roles from outside of the intermediate storage in the roll changer and / or an application of residual rolls or sleeves Do not interfere with the reel changer and the intermediate storage. A further advantage is that a security area is combined around the roll changer and a roll storage area, thereby saving space, incurring lower investment costs in demarcation and securing facilities, and arranging an intermediate storage for rolls to be processed with the roll changer in the immediate vicinity of the roll changer , Thus, an exchange of a replacement role to take place very quickly and easily, even if it is not completely used up and should be kept. Another advantage is that fewer infeed and outfeed operations are required by an arrangement of the intermediate storage in the security area, which means not only less safety devices, but also less monitoring work and thus less possible malfunction.

A further advantage of an embodiment in which a transport path of a second transport means extends at least in the security area and at least outside the security zone perpendicular to the rotation axis of the receiving arms arranged on the support means and / or at least two memory locations on a same side of a transport path of a second transport along this transport path of the second transport means are arranged one behind the other and / or at least one storage space on a first side and at least one storage space are arranged on a second side of a transport path of a second transport means is that a movement of rolls of material not unnecessarily often in their direction must be changed and that the arrangement of more than two memory locations increases flexibility of the intermediate storage.

Another advantage of an embodiment in which a second transport through the opening at least between the receiving and / or delivery area of the roll changer and a position outside the security zone is designed to be movable and preferably a opening penetrating guide is arranged and that this guide at least one transport path is formed of the second transport in the security zone and / or out of the security zone out setting, is that thereby only a second transport for a precise implementation of transport operations is necessary. In particular, this advantage exists if the second transport means is designed as a transfer and / or lifting table and / or if at least one roller is arranged to be fed by means of the second transport means through the opening of the security zone and / or removable from the security zone.

Another advantage of an embodiment in which the at least one first protective cover is designed as at least one gate and / or rolling shutter and / or rolling grille and / or grille and / or plastic curtain and / or net, is that a space-saving arrangement in the case an opened protective cover is ensured. In this context, the at least one first movably arranged protective cover is arranged executable at least partially at least one pivotal and / or rotational movement, namely for example for rolling up and / or opening the first protective cover. Such a pivoting and / or rotational movement can also be superimposed by a translational movement. An advantage in this context is again the possible space-saving arrangement. Particularly advantageously, this pivoting and / or rotational movement can be carried out independently of movements of the second transport means, so that the independence of movements of the protective cover and the means of transport remains ensured.

A further advantage of an embodiment in which an operating device of the roll changer is arranged, which is located structurally separate from the roll changer at a location outside the security area and / or at a distance of at most 1 m from boundaries of the security area, consists in a significantly increased Safety of operators using the operating device.

An embodiment of the at least one shut-off device as persons physically preventing a passage of this shut-off device, which is preferably not exclusively designed as marking and / or lettering and which preferably has a dimension in a vertical direction which is at least 50 cm, more preferably at least 100 cm and even more preferably at least 150 cm, there is a further increased safety of operators.

A further advantage is that movements within a security zone can be carried out independently of and separate from movements outside the security zone, for example, an inlay or removal process can be carried out in an intermediate store, while at the same time a processing process, for example gluing, takes place in the roll changer. In addition, a sleeve container can be moved by means of a second transport in a discharge position before or during the bonding process.

Another advantage of an embodiment in which the security zone is located within a security area is that it does not require the provision of an additional security lock.

Another advantage of an embodiment in which a transfer and / or lift table can be moved through the opening is that an unnecessarily large number of transfer operations can be avoided.

Another advantage of an embodiment in which a transport path of the roller is determined by at least one guide, is that errors such as collisions can be avoided.

Another advantage is that after a transfer of a role of a lifting and / or transfer table to receiving devices of the roll changer the lifting and / or transfer table can be used for other purposes, for example, for handling a subsequent role, regardless of one further role change process within the reel changer and in particular a gluing process. This can save valuable time.

Another advantage is that in one embodiment, in cooperation with the intermediate area having a security area double backup of the operator arises, which are held on the one hand by the security area of an area with increased risk potential, for example by automatic movements of rolls of material, and on the other be protected by the security zone and, where appropriate, catching devices and / or protective covers against possibly flying fragments which could otherwise possibly leave this security area via demarcations, for example fences, of the security area. This avoids unnecessarily large expansion of the security area. In addition, the security area can be entered safely despite the reel splitter being in operation, if there is currently no danger in the security area outside the security zone, as might occur, for example, from moving first means of transport.

A further advantage is that a protective zone and a protective cover that separates this protective zone from a remaining area lying outside the protective zone spatially separate an operator from the roll changer and thus protect it. Furthermore, by a structurally separated from the roll changer Operating device still operate an operator from a position of the reel splicer in which it has a good overview of operations on the reel splicer.

Another advantage of an embodiment with an arrangement of a buffer with at least one storage position in the security area and a pivotability of arranged on the second transport rollers is that can be corrected for example by a position of a roll by means of a corresponding method, without this from the security area to have to escape without having to enter the security area and without using additional facilities.

Another advantage of a pivoting embodiment is that corrections of not only small angular misalignment but also orientation errors of 180 ° can be compensated for, even though the trapping device is arranged close to the roller. Such an orientation error is present, for example, when the roller is arranged with the wrong winding direction. A further advantage is that a transfer and / or lifting table and / or arranged thereon or as part of its pivoting device is used to perform these pivoting movements, so that no further devices are necessary, for example, additional embedded in the ground turnstiles or the like ,

Another advantage of an embodiment in which an unpacking station is located outside the security area containing the intermediate storage is that operators can operate at this unpacking station without having to enter the security area. In conjunction with the memory locations, this results in a particularly high level of flexibility coupled with a high level of security for the operators.

In particular, improved hazard coverage is based on Non-contact protective mechanisms for the field of automatic roll placement provided on a reel changer, which ensures a permanent protection of the secured area even with different roll diameters and the removal of residual sleeve containers. The "outward widening" of the security area makes it possible to handle a wide variety of roll sizes without the need for restrictions due to safety margins for structurally limited passage widths (eg adjacent units, building walls or columns, etc.). This can then z. For example, a width of access to the security area can be significantly increased in order to be able to comply with distance measurements to fixed edges in each case. In this context, however, is a particularly powerful protection device at the access limits, ie in the access area of particular advantage.

Particularly advantageous in conjunction with a widened access are sensor systems which allow a distinction between permissible passage and impermissible passage through access to the security area. This is especially true in the event that an admissible object, z. B. passes through a role, however, a person at the same time next to the role passing through the access is recognized as "prohibited". In particular, in this case an embodiment is advantageous, wherein a sensor subsystem allows detection of permissible passages, rollers and / or means of transport, and accordingly inhibits a reaction, and a second sensor subsystem is permanently "armed" and on the passage of z. B. persons is addressed. Also for the latter, in the presence of certain operating situations, the reaction of the protective device with respect to an initiation of countermeasures, such. As a stopping of movement processes and / or a machine to be disabled or be. Alternatively, a camera or camera-like device can be provided as a sensor system, by means of which a detection result obtained via an evaluation device is checked for admissibility.

In an advantageous development, the protective device, in addition to a protective function, also has an integrated muting function, which saves the expense of setting up an additional device for the muting function. This muting function of the sensor system itself can be achieved by distinguishing objects permitted and prohibited by the pattern of passage through the plurality of light beams, in particular by means of a suitable circuit and / or implemented evaluation routine. For example, it may be provided as a rule that - at least in a height section to be considered - only a contiguous area of superposed light beams may be interrupted simultaneously. The muting function thus allows a temporary deactivation of parts of the protective device or the entire protective device. Preferably, the penetration of objects is allowed without the safety device to operate.

In a preferred embodiment, the light beams are evenly spaced from each other and are inclined to the horizontal, wherein the light beams in other embodiments, also horizontally extending and a surface of the light grid can be arranged inclined to the vertical.

A plane formed by light rays of the light grid can be inclined in an advantageous embodiment to a vertical, z. B. parallel to be hedged border of the access level. An incoming object in the transport direction with a vertical leading edge interrupts in this way the light beams one after the other in a continuous sequence. However, a person entering by mistake will not succeed. Slight variations in vertical alignment, such as those caused by winding faults, are "warped" by the skew of adjacent beams of light. The "resolution" or the "tolerance" can be optimized by the distance of the light beams and / or the strength of the inclination.

Another advantage is that a method for correcting an alignment a role in the order of his steps is very flexible and can be adapted to each situation. Thus, for example, steps of other methods can be carried out in between and it is possible, depending on spatial conditions and just free storage locations to proceed flexibly, for example, to perform linear movements before or after pivotal movements or to divide linear movements into several steps.

The advantages mentioned in particular also arise analogously in connection with a method for using the roll changer with safety device.

A roll changer 01; For example, a roll changer 01 a rotary-web press has at least one pair of support arms 02 for receiving a roller 03, z. B. roll of material 03 on. The support arms 02 are arranged on a continuous or divided traverse 06, which, for. B. pivotable about its longitudinal axis, is mounted in frontal side frames 04 or are. As a side frame 04 z. As a whole, the vertically supporting frame parts as well as possibly on these frame parts directly arranged switching and / or side boxes summarized. Other subsequent aggregates or components should preferably not fall under this. A total width of the roll changer 01 thus amounts to the outside of the frame (if applicable, including the side box) to the outside of the frame (if necessary, including the side box). To accommodate a roller 03 and / or deliver a residual role, the support arms 02 can be pivoted about the cross member 06 by a drive motor, not shown. To accommodate the roller 03 each support arm 02 has a corresponding receiving device 07, z. B. one engaging in a roller sleeve mandrel 07, wherein each pair preferably at least one mandrel 07, but in particular both mandrels 07 rotatory -. B. via a drive motor 08 - are positively driven. In particular, the receiving devices 07 have an axis of rotation, which preferably extends from one side frame to the other side frame. Preferably, the support arms 02 in the longitudinal direction of the traverse 06, in particular in a direction parallel to a rotational axis of a aufgeachsten roller 03, formed over at least one positioning range positionable. This allows z. B. an omission / engagement of the mandrels 07 and / or an adaptation to different roll widths and / or a position correction of an aufgeachsten role 03 with respect to their axial position relative to the roll changer 01.

On a front side of the roll changer 01, z. B. a receiving and / or delivery side, is a recording and / or delivery area of the roll changer 01 for its role change accessible by at least one roller 03. Basically, a male roll 03 can be moved by lift truck or other transport devices in a change position of the receiving and / or delivery area. Preferably, it is placed on a transfer and / or lifting table 09, which is movable with at least one to a rotational axis of the roll changer 01 radial component, and its movement z. B. together with the positioning of the support arms 02 a recording or delivery of a roller 03 allows. However, the loading of the receiving and / or delivery area with a new roll 03 is preferably carried out by an automated (ie, automatically moved) system by means of at least one suitable first transport means 11 and preferably also a second transport means 52 preferably rail-guided trolley 11 exist, which preferably automated controlled z. B. along a transport path 10 in the receiving and / or delivery area, in particular on the transfer and / or lifting table 09 is movable, or in a driverless transport vehicle 11 (also called AGV = automatic guided vehicle 11) of a driverless transport system (= FTS ), which spans the roller 03 directly to the change position or to the transfer and / or lift table 09 provided in the receiving and / or delivery area. Preferably, the process of loading a new roll 03 into the receiving and / or dispensing area and / or the process of removing a dispensed residual roll from the receiving and / or dispensing area is automated by a respective control. The inclusion of the new roll 03 or delivery of a residual role by the roll changer 01 (possibly with the assistance of a transfer and / or lifting table 09) is then preferably also automated. The receiving and / or delivery area is characterized in particular by the fact that at least one roller 03 can be brought into contact with the receiving devices 07 arranged on the support arms 02 of the roll changer 01 and with a first transporting means 11 in the receiving and / or delivery area.

Preferably, and in particular in an illustrated advantageous embodiment, a transport of a new roll 03 from a warehouse, not shown, and / or preferably from an immediate location of the roll changer 01 arranged intermediate storage 51 is carried to the transfer and / or lifting table 09. In a transport from the not shown bearing can be a reload on a to be loaded reel changer 01 associated transfer point 12, passed to the example, a arranged on a first transport means 11 roller 03 from an outer loading circle together with the first transport 11 to a second transport 52 within the intermediate storage 51 becomes. From the bearing, not shown, rollers 03 can thus be conveyed either directly to the receiving and / or delivery area of the roll changer 01 or in a storage position 53 in the intermediate storage 51. The second transport means 52 is preferably designed as a self-moving rail 52 or route 52 for first transport means 11, in particular for trolley 11 and / or AGV 11, so that thus located on a trolley 11 or AGV 11 roller 03 with this together to a Storage space, so a storage position 53 can be transported in the intermediate storage 51 or in the receiving and / or delivery area. Further preferably, the transfer and / or lifting table 09 itself serves as a second transport 52 and / or the second transport 52 is designed as a transfer and / or lifting table 09. The outer loading circuit may be either manually controlled or operated means of transport (eg, forklifts, rail-mounted trolleys, pallet trucks, or a combination thereof), or at least in part by automated driverless systems (eg, FTS, AGV, 11 system-controlled rail-bound Trolley 11, first transport 11 or combinations) may be formed. Thus, either nothing or at least a first transport means 11 or a first transport means 11 and at least one roller 03 arranged thereon can be arranged on the second transport means 52. In the latter case, therefore, the roller 03 is also explicitly arranged on the second transport 52.

The mentioned storage positions 53 of the intermediate storage 51 are to be distinguished from another, for holding positions, the short-term storage of rollers 03 suitable places, so-called memory locations of the second kind at a stop of a first transport means 11 and a roller 03 arranged thereon. Such holding positions can in principle arise at any point along the transport path of the first transport means 11, For example, on at least one feed track, can be introduced via the first transport means 11 and / or rollers 03 in a security area 17 and on which a short stop, for example, for registration operations can be performed. Similarly, at least one Abführgleis can be arranged, which can serve a removal of residual rolls or sleeves. Such storage positions 53 are preferably characterized by the fact that rollers 03 and / or first transport means 11 arranged in these storage positions 53 do not obstruct or prevent further transport operations. In particular, storage device 53 are therefore no passage positions along transport paths first transport means 11, in particular no passage positions, which in a printing operation of the printing press and / or a loading operation and / or unloading operation of the roll changer 01 inevitably occupied by another first transport means 11 or the second transport means 52 and / or have to be passed. In particular, first transport means 11 and / or rollers 03, which are arranged completely in memory positions 53, out of contact with second transport means 52. In particular, the second transport means 52 does not represent storage positions 53 for first transport means 11.

In order to make as little change of direction when transporting rollers 03 to the reel splitter 01 required, preferably a transport path in the intermediate storage 51, on which the second transport 52 is movable, extends in virtual extension of a web running direction of the cooperating with the roll changer 01 printing press. Preferably, the transport path of the second transport 52 extends at least in the security area 17 and at least outside a safety zone 57 explained in more detail laterally perpendicular to the axis of rotation of the support arms 02 arranged receiving means 07, more preferably along a horizontal direction. Preferably, at least two memory locations 53 are arranged one behind the other on a same side of the transport path along this transport path of the second transport 52 and / or at least one memory location 53 on a first side and at least one memory location 53 on a second side of the transport path of the second transport 52. This means that preferably a plurality of storage positions 53 are arranged side by side in a direction in which the second transport means 52 is movable. In particular, therefore, preferably more than two storage positions 53 are arranged.

At the transfer point 12, for example, the new roller 03 is transferred to an inner feed circuit, by which the positioning of the roller 03 for the roll change or storage is carried out and through which a grateful residual roll or sleeve is transported out of the reel changer area, for example in a storage position 53rd of the intermediate bearing 51 back or out of the area of the intermediate storage 51. The inner feed circuit thus preferably has a rail-bound, automatically driven second transport means 52, which is itself movable and can accommodate a trolley 11 or AGV 11 formed first transport means 11 and then with this and possibly arranged on this roller 03 together is. In this case, preferably the first transport means 11 formed as a trolley 11 or AGV 11 from the transfer point 12 on the transfer and / or lifting table 09 into the receiving and / or delivery area and / or into one of preferably several transfer position 54 to one or preferably several storage position 53 movable. In particular, the first transport means 11 can be arranged on the second transport 52. Between the transfer position 54 and the storage position 53 so empty first transport 11 or loaded with a roller 03 first transport 11 are interchangeable. The second transport 52 may preferably be moved directly between at least one transfer position 54 and the transfer point 12. The intermediate storage 51 has at least one, at least one storage position 53 associated transfer position 54. The second transport means 52 is arranged or can be arranged in the at least one transfer position 54, a first transport means 11 with or without a roller 03 being interchangeable between the second transport means 52 arranged in the at least transfer position 54 and at least one storage position 53 of the intermediate storage 51.

The control of the transfer and / or lifting table 09 and the control of Tragarmbewegungen are advantageously so logically linked together that a coordinated movement of both the transfer and / or lifting table 09 and the support arms 02 an automated role change without external, especially without manual intervention allows. A load of new rolls 03 can z. B. from a first page to the roll changer 01, z. B. from a feed side SI forth, take place. Disposal of residual rolls and / or sleeves can, for. B. by means of a transport means provided for this purpose 13 (eg., A rail-guided, in particular also automatically operable Restrollen- and / or residual sleeve container 13), on another side, for. B. Restrollenseite SII, go out. In particular, a feed of new rolls 03 and / or a disposal of residual rolls and / or sleeves from the receiving and / or delivery area in a direction perpendicular to a rotational axis of a aufgeachsten roll 03 take place.

Both the automated loading of new rollers 03, in particular in the inner loading circle and in the intermediate storage 51, as well as the automated changing process itself involves considerable risks for present operating personnel. For this reason, as set forth above in the prior art, a variety of backup options have already been proposed, which are intended to minimize the risk of accidents.

In an embodiment, for example, also shown in the figures, the risk is reduced, for example, by the fact that the operating personnel no longer necessarily penetrate into the danger zone, and also in particular do not penetrate unnoticed may allowed. This is achieved by providing, for example, on the receiving and / or delivery side of the roll changer 01 the security area 17 containing an intermediate storage 51 or the security area 17 formed as an intermediate storage 51, which is essentially completely bounded by boundaries in such a way that it is operationally entered preferably exclusively via one or more sensory monitored access 16 can take place. Limitations of the security area 17 and / or the intermediate storage 51 are on the one hand as the roll changer 01 itself and / or as one or more further, subsequent or spaced units and / or mechanical shut-off 14 or shut-off 14, z. As fences or fence sections and / or on the other hand, for example, as one or more, in particular two, sensory monitored access 16 is formed. With respect to a boundary of the security area 17, protective covers 56; 62 and catcher 58 considered as components of the roll changer 01. The sensor-monitored accesses 16 have an access guard or a protective device with a sensor system and with the sensor signals evaluating means. Entering is a normal, non-violent entry through destruction or overcoming lock-out measures. Preferably, at least one rail cooperating with the at least one first transporting means 11 is arranged so as to project through at least one access 16.

In order for the reel changer 01 to be operated safely for the operating personnel, it is preferable for at least one operating device 18 or an operating element 18, eg a control element 18 to be used. B. a control panel 18, provided with at least basic operating functions, which is structurally separated from the roll changer 01 at a location outside of the security area 17 and / or at a distance of at most 1 m from the boundaries of the security area 17 location. This location is preferably outside the security area 17 and thus outside of the intermediate storage 51 and is therefore in any case by an outside of the security area 17 and thus preferably also outside of the intermediate storage 51 located operator accessible. This control panel 18 is preferably not on the side frame 04 itself, but spaced from this, but it, for. B. via appropriate lines or line-free (optical or electromagnetic radiation such as wireless or W-LAN, etc.), is technically connected to the control and / or sensor of the roll changer 01 and / or the inner feed circuit.

The control panel 18 has z. B. at least one display 19, z. As a display 19, which is used for error display and / or visualization of the roll changer 01 with its functionalities and / or the inner feed circuits. Furthermore, the control panel 18 has a switch 21 for "STOP & LOCK" of the roll changer 01 with possibly the inner feed circle, as well as a switch 22 for "EMERGENCY STOP" of the press or machine section affected by the roll changer 01. Further, preferably buttons 23 for selecting the display of the roll change 01 and / or the roller 03 and / or the inner feed circuit and / or the role memory related operating or setting parameters and z. B. designed as a number block 24 keys 24 (possibly with escape, enter and clear function) for changing and / or input of numerical values for selected parameters. For simplified operation of masks displayed on the display 19, a cursor control 26 or a trackball or even a computer mouse can be provided. The keys 23; 24 may be provided in the conventional sense as individual buttons (mechanical, optical, electronic) or partially or all of them as areas of a touch-sensitive display 19.

The control panel 18 may be on its own foot or on a shut-off device 14, z. B. a shut-off fence 14, or be arranged on a unit adjacent to the reel splitter 01 aggregate. However, the control panel 18 is provided in a location that allows the operator to operate on the control panel 18 while viewing the receiving and / or dispensing area of the roll changer 01.

Of particular advantage is this arrangement of an "external" control panel 18 in conjunction with a measure, the security area 17, in particular on the feed side SI, not only up to Seitengestellflucht, but the reel splitter 01 and its receiving and / or delivery area further outward extend and / or at least one monitored by the protection device or its sensor system access 16, in particular on the feed side SI, not directly in the range of Seitengestellflucht, but further away from the roll changer 01 away. The arrangement of the intermediate storage 51 in the security area 17, a correspondingly large distance is advantageous anyway. Preferably, at least at the level of an escape of the transport path 10, this extended area of the security area 17, which extends beyond the escape F of the frame outer side, or the monitored access 16 displaced outwards, is provided. As explained above, this extended security area 17 is subsequently limited by corresponding shut-off devices 14, the roll changer 01 itself, possibly adjacent aggregates and possibly at least one further monitored access 16. Also on an opposite side, z. B. the residual roll side SII can be a monitored access 16, z. B. also be provided from the escape F farther outward access 16.

The comments made for the lateral extension of the limited security area 17 preferably apply in conjunction with a transfer point 12 from an outer to an inner loading circle, wherein the transfer point 12 is arranged on one side of the security area 17. The monitored access 16 then represents a kind of lock 16. By this relative arrangement between the boundaries of the security area 17 and the transfer point 12 an accident is prevented, which due to the transfer of a z. B. tons of roller 03 could result in the inner feed circle. If the control panel 18, as stated above, accessible from outside the security area 17, so is a risk of Personal accident minimized due to role transfer. The transport path 10 of the inner feed circuit may nevertheless generally extend beyond the access 12 - for example, on an outer side, the transport means 11; 13 can be subjected to maintenance and / or adaptation (eg fitting with adapters for smaller / larger rollers). However, the transfer point 12 of rollers 03 preferably remains in the security area 17.

Preferably, if an unscheduled and / or impermissible passage through the monitored access 16 is detected by the protective device, for example, the sensor system, a fault signal is generated and thereby an optionally forthcoming or ongoing transfer process by appropriate signal processing via corresponding, with the inner and / or external charging circuit signal technically connected control means aborted or initiated a controlled termination at least. Under unscheduled passage is to be understood in the broadest sense, the detection of a signal state of the sensor system, which is not explicitly allowed as allowed. This may most simply be an interruption of one or more beams or sound waves of a system of one or more transmitter-detector systems arranged in the manner of a barrier. If, in one embodiment, the system is capable of distinguishing between a roll 03 to be delivered (or else a means of transport 11, 13) and a different one (for example a person), this can be done in the logic with regard to "scheduled" or "interruption" "Permitted" and "Unscheduled" or "Prohibited" Entries (Interferences) must be taken into account accordingly. Also, a "scheduled" or allowed passage may be present if, for example, appropriate operating situations exist, as shown for example by a standstill of the relevant roll changer 01 or even the machine or section.

Preferably, parts of the protection of the relevant access 16 so z. B. for loading the roller 03 are deactivated or at least one thereby caused disturbance to be defined as allowed.

The o. G. Safety measures are particularly advantageous in connection with sensor systems, which ensures the most secure detection of "unauthorized" passages, but z. B. the desired passage of a roll 03 to be supplied or a means of transport 11; 13, for example, first transport means 11 does not inhibit. Preferably, the sensor system - at least in part - as a non-contact system, eg. B. as operating with electromagnetic or sound waves system.

In an advantageous embodiment, the protective device has a first subsystem or a first sensor subsystem which, for example, deactivates when a roller 03 passes, or at least classifies its signal state as permitted or inhibits a possible reaction with respect to a reaction as a result of a change of state. These possibilities are to be understood in the following under a deactivation of a sensor system or a sensor subsystem. Preferably, the protective device additionally z. B. a second, permanently active, non-contact subsystem or a second sensor subsystem for permanent protection of the surrounding area of the roller 03 on.

The first sensor subsystem includes several, z. B. two light beams 31, which secure the passable by a roller 03 and a Restrollen- and / or residual sleeve container 13 area, wherein the first sensor subsystem for enabling the extension and retraction is deactivated. As far as is spoken only by a retractable into the secure area roll 03, this refers in the same way to retractable Restrollen- and / or residual sleeve container 13, a trolley 11 or a driverless transport vehicle 11 and the reverse movement sequences when extending the roller 03, a rolling carriage 11 or the residual roll and / or residual sleeve container 13 or the driverless transport vehicle 11.

The second sensor subsystem includes z. B. a horizontally extending in a first embodiment light beam 32, which is a distance of z. B. at least 50 mm to the largest (maximum processable) roll diameter. Especially with larger roll diameters, however, such a second protective device has proved to be disadvantageous. As Fig. 3a can be removed, there is a risk that a smaller person can run together with the roller 03 in the secure area of the roll stock and thus can be injured by moving machine parts or the moving roller 03.

Fig. 3b shows an advantageous arrangement of a protective device for the field of automatic roll stocking. The protective device in turn comprises a first, non-contact, but deactivatable sensor subsystem at or at the access limits, ie in the access 16, with two light beams 31, that of the roller 03 or the Restrollen- and / or residual sleeve container 13 or the driverless Securing transport vehicle 11 passable area. For permanent protection of the surrounding area of the roller 03 serves a second, permanently active, non-contact sensor subsystem. The second sensor subsystem comprises two light beams 32 which, starting from points located above the roller 03, lead laterally past the roller 03 to near the bottom. Out Fig. 3b It can be seen that even a protective device designed in this way can not provide sufficient protection. The fact that the light rays 32 extend past the roller 03 almost to the floor, there is a risk that the light rays 32 can be exceeded by a person who runs along, for example, when inserting next to the roller 03.

Fig. 3c shows a further advantageous embodiment of the protection device for the field of automatic reel loading, especially with wide, and therefore particularly secure access 16. This protection device, in contrast to the vorgenanten solutions in a first sensor subsystem a light grid 33 with a Variety of at least two, preferably more than 5, in particular more than 10 light beams 31 for a non-contact protective device at the access limits of the secure area of the automatic roll feed. The light grid 33 (or its "stops") can be deactivated (muted) for retracting or extending rollers 03 or remaining roller and / or residual sleeve containers 13 or driverless transport vehicle 11. In addition, a second permanently active, non-contact sensor subsystem for permanent protection of the surrounding area of the roller 03 is provided, which will be described below. It should be pointed out once again that the access limits to be protected can be located not only on the loading side SI but also opposite the loading side SI. Protective devices must then be installed on both sides if both sides are freely accessible to persons. The non-contact sensor system or subsystem secures, in conjunction with an evaluation unit, the access boundary 16 to be protected, ie the access 16, by the light grid 33. By means of a special additional device described in more detail below, the first sensor subsystem can be deactivated in the above-mentioned sense if a "permitted" object is detected.

In the illustrated embodiment, a light grid 33 by a plurality of mutually parallel, z. B. substantially horizontally extending light rays 31 is formed. The light beams 31 of the light grid 33 are associated with a transmitter 36 and a receiver 37 (eg. Fig. 4 and 5 ) positioned at the end points of the light beams 31. The light grid 33 is connected to an evaluation unit, which is not shown. The evaluation unit detects the order of interruption of the light rays 31 when retracting and / or extending a roller 03 or a residual roll and / or residual sleeve container 13 or a driverless transport vehicle and deactivates the protection device with respect to the light curtain 33 upon detection of a known object which is allowed access to the secure area. In the evaluation z. B. evaluated, whether the individual light beams 31 of the light grid 33 in succession interrupted or released again. It does not matter how many or in which area the individual light beams 31 are interrupted. As a rule, however, z. B. that gaps between the interruption of the individual light beams 31 are not allowed.

Regardless of the protective device can still at least one, preferably a group of several, z. B. two or four in particular, for example, designed as photocells 34 sensors 34 for a so-called. Muting include, in particular a plurality of reflection photocells 34, which are viewed in the transport direction T spaced from each other, and wherein at least one, z. B. whose two pairs in front of and one or a pair in the transport direction T after the light grid 33 are arranged. In principle, a sensor 34 can also be arranged before and after the light grid 33. These serve to deactivate (muting) the light grid 33 upon detection of a known object, in particular a residual roll and / or residual sleeve container 13, which due to the shape of the evaluation of the interruption order of the light beams 31; 32 complicate and reactivate. Furthermore, the reflection photoelectric cells 34 are connected to an evaluation unit, not shown. The group of both sides of the light grid 33 arranged sensors 34 act z. B. in terms of muting with means of transport 11; 13, z. B. trolley 11 and / or Restrollen- and / or residual sleeve containers 13 together. To recognize the transport means 11; 13, z. B. the Restrollen- and / or residual sleeve container 13, provided at the height of the cooperating sensors 34 with reflective strips. The light grid 33 or in particular its evaluation is muted (switched off, in particular deactivated in the above sense), when the reflection strips are detected on a residual roll and / or residual sleeve container 13. After passing through the Restrollen- and / or residual sleeve container 13 through the access protection receives in the transport direction T last, z. B. at a total of four fourth reflection photocell 34 no reflection of the light beam more, so then the light grid 33 is activated again.

The muting function can be realized in the case of an external charging circuit with driverless transport vehicle 11 with one, or a pair of two sensors 44, in particular two reflection photo cells 44 only on the outside, because the driverless transport vehicle 11 does not completely through the light grid 33, but only a piece in the security area 17 retracts to deposit the roll 03 or to pass. The first reflection photocell 44 detects z. B. the reflective strip, which is positioned on the transport vehicle 11 corresponding to the height of the arrangement of the reflection photocells 44, and turns off the light grid 33 or deactivates at least one classified as "unauthorized" reaction of the protection device. If the second reflection photographic cell 44 no longer receives reflection of the light beam when the driverless transport vehicle 11 retracts, the light grid 33 or the reactivity is reactivated. For example, upper, z. B. the two uppermost light beams 31 of the light grid 33 and their evaluation remain z. B. permanently active to prevent intrusion of a person or object together with the roller 03 or the Restrollen- and / or residual sleeve container 13 in the secure area of the automatic roll stocking with deactivated danger coverage by the light grid 33. These two top light beams 31 of the first sensor subsystem then make light beams 32 of a method described above, here then z. B. not specifically required second subsystem.

In an advantageous embodiment, however, a second, permanently active, non-contact sensor subsystem is provided which comprises at least one light beam 32 extending transversely above the roller 03 from a transmitter 38 to a receiver 39. In particular, two light beams 32 are provided, which extend transversely to the longitudinal extent or axial direction of the roller 03 and intersect at a slight distance above the roller 03 and are guided in their further course close to the roller 03 and the roller container 13. The point of intersection of the two light beams 32 is preferably only a few centimeters, z. B. <15 cm, in particular <8 cm, preferably <5 cm, above the upper roll edge and the light rays 32nd run below the crossing point then at a distance of a few millimeters, z. B. <15 mm, in particular <8 mm, preferably <5 mm up to a few centimeters on the roller 03 over. The light beams 32 thus have their upper end points above the roller 03, but outside the roller extension. The lower end points are below the top of the roll.

In the illustrated embodiment, z. B. also reflection light barriers are used. The second, permanently active, non-contact sensor subsystem comprises for each light beam 31 then z. B. a combined transmitting and receiving unit 38; 39 (instead of transmitter 38). The light beam 31 is then transmitted from an opposite reflector 39 '(instead of receiver 39) back to the transmitting and receiving unit 38; 39 thrown. This beam guidance can also be used in the light beams 31 of the light grid 33, in which case the transmitter 36 is likewise replaced by a transmitting and receiving unit 36; 37 and the receiver 37 is replaced by a reflector 37 '. In the second, permanently active sensor subsystem and / or in the light grid 33, one-way light barriers, in which transmitter 36 and receiver 37 are arranged opposite one another, can also be used instead. In alternative embodiments, all light rays 31; 32 of the light grid 33 and the second permanently active sensor subsystem each have exactly one transmitter 36 and one receiver 37. In these cases, to guide the light beams 31; 32 requires several deflection mirrors. As transmitter 36; 38 may be an infrared or visible light emitting diode or laser diode and as a receiver 37; 39 a phototransistor are used. It has proven to be advantageous if the position of the transmitting and receiving units 36, 37; 38, 39 and the reflectors 39 '; 37 'can be changed.

A plane E formed by a plurality or all of the light rays 31 of the light grid 33 can, in an advantageous embodiment, form a vertical plane running along the boundary of the access 16 to be protected, ie with one along the one to be secured Border running vertical plane S fall together. An object with a vertical leading edge entering in the direction of transport T thus interrupts the light beams 31; 32 at the same time. However, a person entering by mistake will not succeed.

In a particularly preferred embodiment of the light grid 33, a plane E formed by a plurality or all of the light beams 31 of the light grid 33 extends inclined to a vertical, z. B. parallel to the boundary of the access 16 to be hedged plane S. An incoming in the transport direction T object with a vertical leading edge interrupts in this way the light rays 31 successively in a continuous order. However, a person entering by mistake will not succeed. Minor fluctuations in the vertical alignment, such as may be caused by winding errors, for example, are "distorted" by the oblique offset of adjacent light beams 31. The "resolution" or the "tolerance" can be optimized by the distance of the light rays 31 and / or the inclination angle φ between the plane E and the vertical. The light beams 31 (ie also the transmitters 36, eg on a light bar 47 forming a structural unit or the receivers 37 on a sensor bar 48 forming a structural unit) are e.g. B., preferably equidistant, at a distance of 20 to 100 mm, in particular 30 to 60 mm, arranged to each other. The inclination angle φ is z. B. between 8 ° and 25 °, preferably at 12 ° to 18 °.

Due to the obliquely arranged light grating 33 in conjunction with light beams 31 which are discretely spaced apart in height and in the transport direction T, a minor change of sign extending over a merely small area is "forgiven" in the slope of the passing object edge or the envelope which can be seen from the side. , This is exemplified in Fig. 6 clarifies, where Fig. 6 a) a regular permitted object, b) an admissible object with slight deviation in the leading edge of the object (eg indentation) and sloping lower edge and c) an impermissible form with non-continuous signal sequence.

The different transmitters 36; 38 and receiver 37; 39 and possibly provided muting sensors 34; 44 are advantageous in two access 16 laterally limiting, opposite frame members 42; 43 or columns 42; 43, which may also be parts of subsequent shut-off devices 14. In this case, sensors 34; 44 may be arranged for muting on only one of the two sides, if it is ensured that reflection strips of the cooperating object are always present at least on the side facing this side.

By pulled to "outside" security area 17, a passage width b16, z. B. width b16 of the monitored access 16 against an otherwise possibly by adjacent stationary obstacles 45, for example, adjacent units and / or building parts such. B. building walls or in particular building supports 45 in so-called. "Rollenkellern" limited width can be significantly increased, whereby even stronger rollers 03 are automatically deliverable.

In a further development, the signal processing routine assigned to the sensor system can also be connected to a computing and / or storage device of a higher-order roller transport system and / or the control of the roll changer 01 and / or a control of the outer feed circuit in such a way that information about the size / Width of the roll 03 to be supplied can be used in the evaluation with regard to the permissibility of the passage.

In all cases, if an unscheduled or impermissible passage through the monitored access 16 is detected by the protective device, ie by the sensor system or a sensor subsystem, generates a fault signal and thereby possibly an upcoming or ongoing transport or transfer process by appropriate signal processing corresponding, with the inner and / or external charging circuit signal technically connected control means aborted or a controlled termination at least initiated. For the injury (disturbance) of different sensor subsystems or for different forms of injury of a sensor system or subsystem, different measures to be triggered by the injury (disturbance) can be provided. It can also be provided that in special, or in all incidents an optical and / or audible warning device 41, z. B. warning light and / or siren is activated, which is preferably arranged in direct visibility to the access 16, in particular in the immediate vicinity of or directly at the entrance 16.

The operating element 18, which can be reached by the operator at a distance from the roll changer 01, is preferably not only a device with narrowly limited influence possibilities, such as emergency functions, but a full-fledged operating panel 18, which has at least the functions of a control panel arranged directly on the roll changer 01 18 with functions for the roll changer 01 itself and to an inner feed circle (eg, a transfer and / or lifting table 09 and / or a transport means 11, 13), and preferably also having functions to roll requests from a warehouse or memory. The control panel 18 with its functions is preferably assigned to a specific roll changer 01 and, although possibly mechanically detachable, but operationally fixed.

A roller 03 can be transported to the transfer point 12, for example, by means of the outer charging circuit. In this case, the roller 03 is preferably already on the designed as a trolley 11 or AGV 11 first transport 11. At the transfer point 12, the roller 03 together with the first transport 11 to the second transport 52, so preferably the transfer and / or lifting table 09 moves, for example, by rails 52 which are arranged on the transfer and / or lifting table 09 and preferably at least in corresponding positions one Formation of permanent notes. The transfer and / or lifting table 09 is then moved in a direction which is preferably perpendicular to a direction in which the first transport means 11 has been moved onto the transfer and / or lifting table 09, for example away from the roll changer 01, for example in a horizontal direction, which is arranged perpendicular to a rotation axis of a roll 03 which is raised in the roll changer 01. The second transport means 52 designed as the transfer and / or lifting table 09 is thereby moved, for example, into one of preferably several transfer positions 54. As soon as the transfer and / or lifting table 09 is in a transfer position 54, the first transport means 11 can, for example, in turn moved along the arranged on the transfer and / or lifting table 09 and in the corresponding storage position 53 rail 52, in a storage position 53 become. The transfer and / or lifting table 09 can then be moved to other positions again. At a later time, the transfer and / or lifting table 09 can be brought back into the same transfer position 54 and the first transport means 11 can be brought together with the roller 03 arranged thereon on the transfer and / or lifting table 09. The transfer and / or lifting table 09 is then moved into the receiving and / or delivery area of the roll changer 01, where the roll 03 is received in the roll changer 03 by means of the support arms 02. In another embodiment, a roll 03 is moved from the transfer point 12 by means of the transfer and / or lifting table 09 into the receiving and / or delivery area of the roll changer 01, bypassing any storage position 53, and is preferably received there by the roll changer 01.

Within the security area 17, a further security zone 57 is preferably set up, which serves to protect operators in the event of a nearly or completely exhausted roll 03 bursting. For rollers 03 with large axial length, for example, six pages in a broadsheet format next to each other in the direction of the axis of rotation of the roller 03 wide rollers 03, such a burst may occur with decreasing roll diameter, especially shortly before Substrate of the roll 03 is used up. In order to protect operators from flying debris around, the further security zone 57 is delimited in all spatial directions.

In one embodiment, the security zone 57 is delimited in at least one direction, which may be, for example, an axial direction of the roller 03 from the transfer and / or lifting table 09, by a second protective cover 56, preferably by the security area 17 and / or the Interim storage 51 delimited. The second protective cover 56 may be designed to be movable, in particular movable relative to the roll changer. In particular, the second protective cover 56 closes at least partially and preferably completely in an operating state at least a first side opening of the security zone 57 and releases the at least one side opening of the security zone 57 in another operating state. Side openings preferably have dimensions of at least 100 cm in the vertical direction. Side openings preferably have dimensions of at least 100 cm in the horizontal direction. As a result, rollers 03 can be moved parallel to their axes of rotation through side openings. The second protective cover 56 is formed, for example, as at least one door 56 and / or roller door 56 and / or rolling grille 56 and / or grille 56 and / or plastic curtain 56 and / or net 56. Such a second protective cover 56 is preferably only opened when a roller 03 has to be moved through the corresponding side opening, for example to be moved into the intermediate storage 51 and / or to the transfer and / or lifting table 09. Preferably, two such second protective covers 56 are arranged on opposite sides of the security zone 57, so that one secures the first side opening for introducing fresh rollers 03 and the other a second side opening for discharging used rollers 03 or empty tubes.

A delimitation of the safety zone 57 upwards is preferably arranged rigidly, but may be flexible and / or elastic in itself, in order to fly a kinetic energy around To be able to absorb debris very well. In at least one horizontal direction, the security zone 57 is limited by the paster 01 itself.

In a first embodiment of the roll changer 01, in a further horizontal direction, which is preferably remote from the roll changer 01, the security zone 57 is preferably delimited by a catching device 58, which is connected to the second transport means 52 and, in particular, can be moved together therewith. Preferably, the capture device 58 is connected exclusively to components of the second transport 52 and / or fully movable together with the second transport 52. This is preferably true even if the second transport 52 is designed as a transfer and / or lifting table 09. The catching device 58 is preferably, apart from a possible pivoting movement, movable in a direction which is perpendicular to a rotational axis of a role 03 aufgeachsten in the roll changer 01. More preferably, the direction is a horizontal direction. The catcher 58 may be formed, for example, as a rigid or at least partially resilient wall 58, or preferably as a fence 58 supported by a series of struts and / or a frame. The joint mobility of the second transport means 52 and the catching device 58 ensures that the safety zone 57 is opened exclusively and always in the direction secured by the catching device 58, if such an opening of the second kind is necessary, for example, if a roller 03 from a Memory position 53 of the latch 51 on the transfer and / or lifting table 09 within the security zone 57 or a partially used up role 03 is to be transported from the transfer and / or lifting table 09 in a storage position 53 of the latch 51. The catching device 58 is therefore the opening of the second type occlusive or closable, preferably completely occlusive or closable. The opening of the second kind has a dimension of at least 100 cm in the vertical direction. The opening of the second type has a dimension of at least 200 cm in the horizontal direction. In this way, rollers 03, with their axis of rotation in the horizontal direction are moved in a direction perpendicular to its axis of rotation through the opening of the second kind to be moved.

For example, the second transport means 52 is brought into a transfer position 54, whereupon a first transport means 11 is transferred together with a roller 03 arranged thereon out of a storage position 53 and onto the second transport means 52 located in the transfer position 54. The second transport 52 and the catcher 58 arranged thereon are then moved together with the first transport 11 and the roller 03 into the security zone 57. In this case, on the one hand, the roller 03 is transported together with the first transport means 11 on the transfer and / or lifting table 09 into the receiving and / or delivery area of the roll changer 01 and at the same time the second type opening of the security zone 57 is closed. Now a Aufachsen the roller 03 can be made while the security zone 57 is completely closed. The second protective covers 56 do not have to be opened for this process.

The second transporting means 52 and / or the transfer and / or lifting table 09 preferably has a pivoting device 59, for example a rotary disk 59, by means of which at least parts of the transfer and / or lifting table 09 and / or at least parts of the second transporting means 52 and / or or at least parts of the roller 03 carrying the first transport means 11 are pivotally mounted about a vertical axis. In this way, the said pivotally mounted components, or at least the roller 03 occupy at least two different horizontal angular positions on the transfer and / or lifting table 09, which may preferably differ by up to 180 ° and more. As a result, on the one hand, it is possible to align the roller 03 with a possible imbalance, for example by a few degrees, so that the receiving devices 07 can optimally engage in corresponding openings of the roller 03 in the axial direction. In addition, rollers 03, which arrive in a certain position at the transfer point 12, by means of the pivoting device 59 by, for example, at least 180 ° be pivoted, whereby a compensation of previously incurred errors is possible. Such errors can take place, for example, at an unpacking station 61, if here a roll 03 is stored and unpacked from the outset in the wrong way. Such an unpacking station 61 is preferably located outside the security area 17 so that operators can work at the unpacking station 61 without having to enter the security area 17. Preferably, at least one rail is arranged to extend from the at least one unpacking station 61 to the at least one access 16. It is also conceivable that a transfer and / or lifting table 09 and / or an intermediate storage 51 serves to supply two opposing roll changers 01 and therefore rollers 03 from the intermediate storage 51 can be arranged in different orientations on the transfer and / or lifting table 09 have to. In one embodiment, rails for first transporting means 11 extend from an unpacking station 61 to at least two different intermediate storages 51 of two different reelstands 01. This enables a saving of costs and a particularly effective working.

The pivoting device 59, for example, turntable 59, may preferably be arranged on the second transport means 52 or be formed as part of the second transport means 52.

In the second step, at least the part of the pivoting device 59 is pivoted without the first roller 03, since the roller 03 is in the storage position 53 of the intermediate storage 51. For carrying out the method, it is irrelevant whether it is a storage position 53 of the intermediate storage 51 or holding position. Preferably, however, a storage position 53 of the intermediate storage 51 is used in order to avoid space problems and not to disturb a running operation of the roll changer.

In a second, preferred embodiment of the roll changer 01 with safety device, which is described below and which, apart from the features described above, can be designed in exactly the same way as the previously described first embodiment, at least one first protective cover 62 is arranged. The at least one second protective cover 62 is formed, for example, as a door 62, roller shutter 62, rolling grille 62, grille 62, plastic curtain 62 and / or net 62. This at least one first protective cover 62 is in at least one first operating state, the security zone 57 to the outside, in particular to the security area 17 towards delimiting and closing arranged. This is at least to be understood that the at least one first protective cover 62 is arranged to prevent access of operators to the security zone 57 and an escape of fragments of a broken material roll 03. The at least one first protective cover 62 is arranged such that, at least in the first operating state, it preferably lies substantially in a plane which has a component in the vertical direction and which has a component which is aligned parallel to a direction of a rotation axis of a roll changer 01 Material roll 03 is located ( Fig. 12 to 15 ).

The at least one first protective cover 62 closes in the first operating state, the safety zone 57 in a horizontal direction which points away from the paster 01 and perpendicular to the axis of rotation of aufgeachsten in the roll changer 01 roll of material 03 is located. In the following, only a first protective cover 62 is mentioned, but this should also include the case in which a plurality of first protective covers 62 are arranged, which share, for example, an opening 63 can close. If in the foregoing and / or below it is mentioned that the at least one first protective cover 62, the opening 63 of the security zone 57 is at least partially closing towards the security area 17 towards, so is always also possible with appropriate reversal of direction that at least a first protective cover 62, the opening 63 of the security zone 57 is moved to the security area 17 releasably moved. In particular, in an appropriate method, both steps can be performed in any order.

In a second, open operating state, the opened first protective cover 62 releases the opening 63, which can be passed in a horizontal direction perpendicular to the axis of rotation of a material roll 03 raised in the roll changer 01. The opening 63 is preferably passable by the second transport 52, which is preferably designed as a transfer and / or lifting table 09. The opening 63 is passable by the second transport means 52 both when the second transport means 52 an empty first transport means 11 is formed supporting, as well as when the second transport means 52 a loaded with a roll of material 03 or rest role first transport means 11 is formed supporting. The opening 63 is also passable by the second transport means 52 carrying the residual roll and / or residual sleeve container 13. In principle, the opening 63 can also be passed by an empty second transport means 52 or by a second transport means 52, which is designed to support only a remaining roll or a material roll 03. Preferably, at least one guide projecting through the opening 63 is arranged, so that the second transporting means 52 and / or the first and the second transporting means 11; 52 along this at least one guide on a defined path through the open opening 63 passes therethrough, in particular can be moved. The guide, which is preferably designed as a rail, is preferably arranged horizontally and perpendicular to the axis of rotation of the roller 03 arranged in the roll changer 01, so that a transport path of a roller 03 into the safety zone 57 or out of this also preferably perpendicular to the Rotation axis of arranged in the reel changer 01 roller 03 is arranged.

The first, closed operating state is preferably given when a roll change is imminent because a residual roll has reached a minimum diameter, when a roll change is being performed or when a roll change has just been completed. In this way, it is ensured that the safety zone 57 is completed at all times which constitute a critical situation with regard to a bursting of a roll of material 03. Under a roll change is in particular the process to be understood that a printing material from a first roll of material 03, which is currently being processed in the roll changer 01, is connected to a printing material a second roll of material 03, for example by gluing, and that at one time the printing material of the first roll of material 03 is completely separated from the sleeve of this first roll of material 03. At least thereafter, printing material is therefore unwound only from the second roll of material 03. Also, a pivoting movement of the cross member 06 can preferably be done when needed and sufficient space when the first protective cover 62 is closed.

The second, opened operating state is preferably given when a previous role change is sufficiently long ago, so that there is no danger and / or if a subsequent roll change is planned sufficiently far away in time and / or if only rolls of material 03 with sufficiently large diameter in the Reel changers 01 are aufgeachst and / or when the roll changer 01 and in particular therein optionally arranged material rolls 03 stand still, in particular no roll of material 03 is arranged to rotate.

The first protective cover 62 can be arranged independently of and in particular in addition to second protective covers 56 which cover possible but not necessarily arranged side openings of the safety zone 57 in the axial direction with respect to an upstanding material roll 03. First and second Protective covers 56; 62 may be the same except for their orientation and dimensions. The first protective cover 62 may additionally or preferably be arranged as an alternative to the above described capture device 58. Thus, in addition to the first protective cover 62, the catching device 58 may also have the opening 63 arranged at least partially wearing and / or closable. The first protective cover 62 has a width that is greater than a maximum dimension in the axial direction of a roll of material 03 processable with the roll changer 01. The first protective cover 62 is preferably designed such that it covers the opening 63 in the first operating state by at least 50%. , preferably at least 75%, and more preferably completely closes, in particular, if only the first protective cover 62 is provided to cover the opening 63.

The first protective cover 62 is thus independent of the first and second transport means 11; 52 movable as a first protective cover 62 and first and second transport means 11; They do not have to move at the same time. If neither a roller 03 nor the first and / or second transport means 11; In principle, the first protective cover 62 can be opened or closed arbitrarily, in particular in contrast to the catching device 58 described in the first exemplary embodiment. This is possible because the first protective cover 62 does not have any translation movements rigid with a first and / or second transport means 11; 52 is connected. The first protective cover 62 has, at least for translational movements, a possible direction of movement with at least one component which lies in a plane whose surface normal lies in and / or against a possible transport direction of the second transport means 52, which is preferably designed as a transfer and / or lifting table 09. Preferably, the possible direction of movement of the first protective cover 62 has a component in a vertical direction. More preferably, the first protective cover 62 is designed as a roll-up door 62 that can be rolled up to open. In particular, the first protective cover 62 with respect to rotational movements about vertical axes not rigid with the first and / or second transport means 11; 52 connected.

In a preferred embodiment, the reel changer 01 thus results with a safety device, wherein the reel changer 01 has the receiving and / or delivery region and adjacent to the reel changer 01 that of an environment through the reel splitter 01 and / or at least one unit and / or the at least one shut-off device 14 delimited by the at least one access 16 enterable security area 17 is formed and wherein the roll changer 01 has the security zone 57, which includes the receiving and / or delivery area and by means of at least one movably arranged first protective cover 62 of the security area 17 is separated and / or separable and wherein the at least one first protective cover 62, the opening 63 of the security zone 57 to the security area 17 towards at least partially occlusive and / or closable and wherein the opening 63 is parallel to a rotation axis of the on the support arms 02 of the roll changer 01 arranged receiving means 07 for rollers 03 extends.

Preferably, the reel changer 01 has the traverse 06, on which the support arms 02 and thus the receiving means 07 for receiving at least one roll of material 03 are arranged, wherein the opening 63 seen from a part of the cross member 06, with respect to a connecting direction of two for the common receiving a roller 03 formed receiving devices 07 between these two receiving devices 07 is arranged lying, is arranged in a direction which is aligned perpendicular to this connecting direction. In an extension of the connection of each two receiving devices 07 of the roll changer 01 are preferably permanently closed boundaries 64 or side shields 64 are arranged, which are not designed to be movable and around flying debris bursted sleeves intercepting arranged or can be.

In this embodiment, the roll changer 01 and an assigned security area 17 are preferably designed such that openings for entering the security area 17 are arranged outside the roll changer 01 itself ( Fig. 12 ; 13 ). In particular, the security area 17 can thereby be fed and / or removed rolls 03, while at the same time a roll change is performed in the roll changer 01. Also movements of rollers 03 within the intermediate storage 17 are so independent of a role change process within the reel changer 07 possible, for example, deposits and / or outsourcing of rollers 03 in or out of memory positions 53rd

This roll changer 01 also preferably has the described security area 17, which more preferably also has the described memory positions 53 and transfer positions 54. This reel changer 01 also preferably has the described transfer and / or lifting table 09; the second transporting means 52 is preferably designed as such. This reel changer 01 preferably also has the described operating device 18. Also, this reel changer 01 preferably has the described device 59 for rotations of at least the rollers 03 about vertical axes.

In one embodiment, the security area 17 is not designed as an intermediate storage 17, but serves merely to delineate a range of danger areas. Then, for example, the security area 17 can have at least two and preferably exactly two accesses 16 and serve exclusively for a secure sequence of roll changes. Such a security area 17 can be made particularly space-saving, in particular in conjunction with a first protective cover 62 with adapted geometry. Such a geometry is given, for example, when guide rails of the first protective cover 62, which may be formed, for example, as a roller shutter 62, a single or multiple curved course and thereby the first protective cover 62 is also curved in a closed state also single or multiple times. Curvatures for winding area, for example, designed as a roller door 62 or rolling grill 62 first protective covers 62 should be disregarded. As a result, the volume of the security zone 57 can be adapted to the requirements, for example, maximum pivoting distances of rolls of material 03, and kept to a minimum ( Fig. 14 ; 15 ). This is particularly relevant when a number of reelstands 01 is to be arranged in a small space without sacrificing ease of use and safety, for example in a series of reelstands 01 arranged below a printing press.

A roll change process then preferably proceeds as follows: Starting from a second operating state, in which the opening 63 is not closed and in which a first roll of material 03 is arranged to rotate and printing material is unwound from the first roll of material 03, first the opening 63 is opened by means of the first Protective cover 62 closed. This occurs, for example, when a minimum diameter of the roll 03 which has just been unrolled is reached and thus, for example, there is an increased risk of bursting of a roll 03. Following this, the actual roll change is carried out by means of appropriate means of the roll changer 01, ie a second printing material web is connected to the first, the first printing material web is separated from its sleeve and the second printing material web is subsequently unwound from its sleeve. Subsequently, the remaining role or the empty shell of the first material web is stopped and brought the roll changer 01, for example, by pivoting the traverse 06 in a position in which the remaining role or sleeve to the first and / or second transport 11; 52 and in particular to the residual roll and / or residual sleeve container 13 can be transferred. After stopping the residual roll or sleeve and before pivoting the traverse 06 and / or simultaneously with it and / or thereafter, the first protective cover 62 is opened, so that after a transfer of the residual role or sleeve to a corresponding first and / or second Transport means 11; 52 and / or the Restrollen- and / or residual sleeve container 13 of this first and / or second transport means 11; 52 and / or this residual roll and / or residual sleeve container 13 can be removed together with the remaining roll or sleeve from the security zone 57. Preferably, the second transport means 52, which is preferably designed as a transfer and / or lift table 09, is already moved together with the sleeve container into a discharge position before and / or during the joining of the first and the second printing material web, in which the sleeve container for receiving one from the roll changer 01 is ready to be removed sleeve.

At least temporarily, with closed security zone 57, at least one further work step is carried out outside safety zone 57, for example delivery of a sleeve container for removal of an empty sleeve and / or storage and / or removal of at least one roller 03 into the housing and / or from the intermediate storage 17 and / or a position correction of a roller 03 by means of the device 59. This results in, for example, an operating state in which two rolls of material 03 are arranged aufgeachst in the roll changer 01 and in which preferably a printing material of a roll of material 03 with a printing material web of the other roll of material 03 connected, for example, is glued and in which preferably the first protective cover 62 is closed and arranged in which preferably designed as a transfer and / or lifting table 09 second transport 52 outside the security zone 57 is. In this operating state, the second transport means 52 may be arranged to be moving outside the safety zone 57 and / or, for example, to carry a sleeve container or another roller 03 to support it.

The result is a method for using the roll changer 01 with safety device, wherein the roll changer 01 has the receiving and / or delivery area and wherein adjacent to the roll changer 01 from the environment by the roll changer 01 and / or at least one unit and / or at least one shut-off device 14, formed by at least one preferably sensory monitored access 16 accessible security area 17 is formed, wherein the security area 17 preferably the intermediate storage 51 for the at least one arranged on the at least one first transport means 11 roller 03 and wherein preferably the intermediate storage 51 apart at least one of which at least one second transport means 52 has a different storage position 53, in which preferably the at least one roller 03 arranged on the at least one first transport means 11 can be stored, wherein the roll changer 01 the security zone 57, which includes the receiving and / or delivery area, wherein preferably the opening 63 of the security zone 57 to the security area 17 towards parallel to the rotation axis of the arranged on the support arms 02 receiving devices 07 erstre and wherein the at least one second transport means 52 is moved through the opening 63 between a position outside the security zone 57 and the receiving and / or delivery area of the roll changer 01 arranged within the security zone 57 and / or is movable, and wherein the at least one first protective cover 62, the opening 63 of the security zone 57 is moved toward the security area 17 at least partially closing or releasing. Preferably, at least one roller 03 is moved by means of the at least one second transport 52 from the security area 17 into the security zone 57. In one operating state, the protective cover 62 is preferably closed and the second transporting means 52 is arranged outside the safety zone 57. At least occasionally, with the protective cover 63 closed, at least one work step is carried out outside the security zone 57 by means of the second transport means 52, preferably within the security area 17 and more preferably, while within the security zone 57 a roll change is performed.

As the at least one step is preferably a delivery of a Restrollen- and / or residual sleeve container 13 for a removal of an empty sleeve and / or a Storage and / or outsourcing at least one roller 03 into and / or out of the intermediate storage 17 and / or storage and / or outsourcing at least one roller 03 into and / or out of the at least one storage position 53 and / or storage correction at least a roll 03 performed.
