EP2563699B1 - Roll changer comprising a safety device and use of a roll changer comprising a safety device for correcting an alignment of a roll - Google Patents

Description

The invention relates to a roll changer with safety device according to the preamble of claim 1 and to a use of a roll changer with safety device for correcting an alignment of a roll according to the features of claim 12.

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 an area coverage 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 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 EP 1 801 057 A1 there is known a reel changer with safety device to which is adjacently formed a safety area which is delimited by an environment and can be accessed by at least one monitored access, which is completely confined so that an operational access can only take place via the access, the security area having an interim storage, that, apart from at least one Zuführgleis and optionally at least one Abführgleis, at least one storage position for at least one roller and at least one transfer position, wherein at least one roller on at least a first transport means can be arranged and the at least one first transport on one second, arranged in the security area transport can be arranged.

By the WO 2009/050332 A1 a reel changer with safety device is known to which adjacent to an environment delimited by at least one supervised access enterable security area is formed, which is so completely limited by limits that an operational access can be made only via the access.

By the EP 1 632 447 A1 an intermediate storage is known which, apart from at least one feed track and optionally at least one Abführgleis, at least one storage position for at least one roller and at least one, the at least one storage position associated transfer position, wherein at least one roller on at least a first transport means can be arranged and the at least one first transport means can be arranged on a second transport means arranged in the intermediate storage, and wherein transport means and / or rollers arranged on the second transport means are arranged pivotably at least about a vertical axis by means of a pivoting device.

The invention has for its object to provide a reel changer with safety device and a use of a reel changer with safety device for correcting an alignment of a roll.

The object is achieved by the features of claims 1 and 12, respectively.

The achievable with the present invention consist in particular that by forming a security zone within a security area operators protected against fragments of broken rolls. This results in the interaction with the intermediate area having a security area double protection of operators who are held on the one hand by the security area of an area with increased risk potential, for example, by automatic movement of rolls of material, and on the other by the security zone and possibly capture devices and / or Protective covers are protected from possibly flying fragments, which could otherwise possibly leave this security area via demarcations, for example fences, in 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 an operating device arranged structurally separate from the roll changer, an operator can still operate from a position from the roll changer in which he has a good overview of operations on the roll changer.

Another advantage is that the safety zone, which may be at least partially limited by a catching device, in at least one other direction by at least one space-saving protective covers, such as a gate and / or rolling shutter and / or rolling grille and / or fall grid and / or Plastic curtain and / or net can be limited.

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

A further advantage is that corrections of not only small angular misalignment but also orientation errors of 180 ° can be compensated for, even though the trap arranged close to the roller is located. 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 is that by an arrangement of a control panel at a location outside of the security area and / or at a distance of at most 1 m from boundaries of the security area remote location and / or a transfer point enclosing extension of the security area at least on the side of the roll feed contributes to a significantly increased safety.

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 reel splicer and a roller storage area, thereby saving space, incurring lower investment costs in demarcation and securing devices, and arranging an intermediate storage for rolls to be processed with the reel splitter 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.

Another advantage is that an unpacking station is located outside the security area containing the intermediate storage so that operators can work on 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, an improved hazardous area protection based on non-contact protective mechanisms for the field of automatic reel placement is provided on a reel changer, which ensures a permanent protection of the secured area even with different reel 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 to accommodate clearance firm edges to be able to comply in any 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 can be provided as a rule that - at least in a height section to be considered - only a contiguous area of superimposed light beams may be interrupted at the same time. The muting function So allows a temporary deactivation of parts of the protection or the entire protection. 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.

A further advantage is that a method for correcting an orientation of a roll in the order of its steps is very flexible and can be adapted to particular circumstances. 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.

A roll changer 01, for example, a roll changer a RollenRotationsdruckmaschine has at least one pair of support arms 02 for receiving a front side of a roller 03, z. B. roll of material 03, which on a continuous or divided traverse 06, the, z. 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). In order to receive a roller 03 and / or deliver a residual role, the support arms 02 can be pivoted about the traverse 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. 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 recording and / or Dispensing side, is a receiving and / or delivery area of the roll changer 01 for the 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 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 can be moved, or in a driverless transport vehicle 11 (also called AGV 11 = automatic guided vehicle 11) of a driverless transport system (= FTS), which spans the roll 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.

In an illustrated advantageous embodiment, a transport of a new roll 03 from a warehouse, not shown, and / or preferably takes place from a disposed in the immediate vicinity of the roll changer 01 intermediate storage 51 to the transfer and / or lifting table 09. In the case of a transport from the bearing, not shown, a transfer can take place at a transfer point 12 assigned to the reel changer 01 to be loaded, at which, for example, a roller 03 arranged on a first transport means 11 is provided by an outer loading circle together with the first transport means 11 is transferred to a second transport 52 within the intermediate storage 51. 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 trolley 11 or AGV, so that thus a roller 03 located on a trolley 11 or AGV with this together to a storage space or 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 second transport means 52. The outer loading circuit can be either manually controlled or operated transport means (eg forklifts, rail-mounted trolleys, lift trucks or a combination thereof) or at least in part by driverless, automated systems (eg FTS, AGV 11, system-controlled rail-bound trolleys 11, first means of transport 11 or combinations). 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 aforementioned storage positions 53 of the intermediate storage 51 are to be distinguished from holding positions, which enable a short-term positioning of the roller 03 when a first transport means 11 and a roller 03 arranged thereon are stopped. 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 over which first transport means 11 and / or rollers 03 can be introduced into the 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 devices 53 are thus no passage positions along transport paths of the first transport means 11. In particular, passage positions which in one printing operation of the printing press and / or one loading operation and / or one unloading operation of the roll changer 01 are inevitably effected by another first transport means 11 or the second transport means 52 occupied and / or must be passed. In particular, first transport means 11 and / or rollers 03, which are arranged completely in storage positions 53, are out of contact with second transport means 52

In order to make the least possible change in direction during the transport of rollers 03 to the reel splitter 01, preferably a transport path in the intermediate storage 51, on which the second transport means 52 is movable, preferably extends in virtual extension of a web running direction of the cooperating with the roll changer 01 printing press and / or a horizontal direction, which is arranged perpendicular to a rotational axis of a aufgeachsen in the roll changer 01 03 role.

At the transfer point 12, for example, the new roll 03 is transferred to an inner feed circle, by which the positioning of the roll 03 for the roll change 01 or the storage is made and through which a grateful residual roll or sleeve is transported out of the roll changer area, for example in a storage position 53 of the intermediate bearing 51 back or out of the range of the intermediate bearing 51 out. The inner feed circle has so preferably a rail-bound, automatically driven second transport means 52, which is itself designed to be movable and can accommodate a trolley 11 or AGV 11 and then together with this and, if appropriate, arranged on this roller 03 is movable. In this case, the trolley 11 or AGV 11 from the transfer point 12 on the transfer and / or lifting table 09 in the receiving and / or delivery area and / or in a preferred multiple transfer position 54 to one or preferably a plurality of storage position 53 can be brought. Between the transfer position 54 and the storage position 53 so empty trolley 11 or AGV 11 or with a roller 03 loaded trolley 11 or AGV 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 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.

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 stated 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 now reduced by the fact that the operating personnel no longer necessarily penetrate into the danger zone, and in particular must not be able to penetrate unnoticed. This is achieved, for example, by providing on the receiving and / or delivery side of the roll changer 01 a security area 17 containing an intermediate storage 51 or a security area 17 formed as an intermediate storage 51, which is essentially completely bounded by boundaries such that an operational entry takes place can only be done via one or more monitored access 16. 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 regard to a limitation of the protection area 17, protective covers 56 and catching devices 58 are considered as components of the roll changer 01. The 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 transporting means 11 is arranged so as to project through the at least one access 16.

So that the reel changer 01 can be safely operated by the operating personnel, an operating device 18 or an operating element 18, for example, is preferred. 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 preferred outside the security area 17 and thus outside of the intermediate storage 51 and is therefore accessible in any case by an outside of the security area 17 and thus preferably outside the intermediate storage 51 located operator. 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. The control panel 18 is, however, in one place provided that allows the operator to operate on the control panel 18 while viewing the receiving and / or delivery 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. heavy roll 03 to the inner Feed circle could result. If the control panel 18, as set out above, accessible from outside the security area 17, so a risk of personal injury is minimized due to the roles of handover. 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 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 outer Feed circuit signal technically connected control means aborted or a controlled abort at least initiated. 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. are disabled for loading the roller 03 or at least one disturbance caused thereby 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 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 trolley 11 or the Restrollen- and / or Residual sleeve container 13 or of 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 a wide, and therefore particularly secure access 16. This protection device has, in contrast to the vorgenanten solutions in a first sensor subsystem a light grid 33 having a plurality of, for. B. more than 5, in particular more than 10, light rays 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 roller 03 or residual roller and / or residual sleeve container 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 11 and deactivates the protective device with respect to a reaction to the light grid 33 upon detection of a known Object that is allowed access to the secure area. In the Evaluation unit is z. B. evaluated whether the individual light beams 31 of the light grid 33 are interrupted in succession or free 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. in a total of four fourth reflection photocell 34 no reflection of the light beam more, so then the light grid 33 is activated again becomes.

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 crossing point of the two Light rays 32 is preferably only a few centimeters, z. B. <15 cm, in particular <8 cm, preferably <5 cm, above the roll upper edge and the light rays 32 are 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 In an advantageous embodiment, it may form a vertical plane running along the boundary of the access 16 to be protected, ie coincide with a vertical plane S running along the border to be secured. 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) a permissible object with slight deviation in the leading object edge (eg indentation) and sloping lower edge and c) represents an impermissible form with a 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 inadmissible 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 a possibly imminent or ongoing transport or transfer process terminated by appropriate signal processing via appropriate, technically connected to the inner and / or outer feed circuit control means or a controlled abortion are 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 Tarnsportmittel 11. At the transfer point 12, the roller 03 together with the trolley 11 or AGV 11 on the second transport 52, so preferably the transfer and / or lift table 09 moved, for example, by rails 52 which are arranged on the transfer and / or lifting table 09 and preferably form at least in corresponding positions an extension of fixed rails. The transfer and / or lifting table 09 is then moved in a direction which is preferably perpendicular to a direction in which the trolley 11 or AGV 11 has been moved onto the transfer and / or lifting table 09, for example away from the paster 01 , For example, in a horizontal direction, which is arranged perpendicular to a rotational axis of a aufgeachsten in the roll changer 01 roller 03. The transfer and / or lifting table 09 is moved, for example, in one of preferably several transfer positions 54. Once the transfer and / or lifting table 09 is in a transfer position 54, the trolley 11 or AGV 11, for example, again along the arranged on the transfer and / or lifting table 09 and continued in the corresponding storage position 53 rail, in a storage position 53 are moved. 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 trolley 11 or AGV 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 rolls 03 of large axial length, for example, six pages in a broadsheet format side by side in the direction of Rotation axis of the roller 03 wide rollers 03, such a burst may occur with decreasing roll diameter, especially shortly before the substrate of the roller 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 at least one direction, which may be, for example, an axial direction of the roller 03 as viewed from the transfer and / or lifting table 09, the safety zone 57 is delimited by a protective cover 56, preferably delimited by the safety area 17 and / or the intermediate storage 51. The protective cover 56 is designed to be movable, in particular movable relative to the roll changer. In particular, the protective cover 56 closes at least a first opening of the first type of the safety zone 57 in an operating state and releases the at least one opening of the first type of the safety zone 57 in another operating state. Openings of the first type preferably have dimensions of at least 100 cm in the vertical direction. Openings of the first type 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 openings of the first kind. The protective cover 56 is formed, for example, as at least one door 56 and / or roller door 56 and / or roller grille 56 and / or grille 56 and / or plastic curtain 56 and / or net 56. Such a protective cover 56 is preferably only opened when a roller 03 must be moved through the corresponding opening of the first type, for example, to be moved into the intermediate storage 51 and / or to the transfer and / or lifting table 09. Preferably, two such protective covers 56 are arranged on opposite sides of the security zone 57, so that one secures the first opening of the first kind for introducing fresh rolls 03 and the other a second opening of the first kind for discharging used rolls 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 be able to absorb a kinetic energy of flying debris particularly well. In at least one horizontal direction the security zone 57 is limited by the paster 01 itself.

In a further, preferably facing away from the paster 01 horizontal direction, the security zone 57 is preferably limited by a catching device 58 which is connected to the second transport means 52 and in particular with this jointly movable. 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 Storage position 53 of the intermediate storage 51 on the transfer and / or lifting table 09 within the security zone 57 or a partially used up roll 03 is to be transported from the transfer and / or lifting table 09 in a storage position 53 of the intermediate storage 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, which are aligned with their axis of rotation in the horizontal direction, can be moved in a direction perpendicular to its axis of rotation through the opening of the second kind.

In one exemplary embodiment, the second transporting means 52 is brought into a transfer position 54, whereupon a trolley 11, together with a roller 03 arranged thereon, is transferred out of a storage position 53 and onto the second transporting means 52 located in the transfer position 54. The second transport 52 and the catcher 58 arranged thereon are then moved together with the trolley 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 trolley 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. Protective covers 56 do not have to be opened for this process.

In a preferred embodiment, the second transport means 52 and / or the transfer and / or lifting table 09 has a pivoting device 59, for example a turntable 59, by means of at least parts of the transfer and / or lifting table 09 and / or at least parts of the second transport means 52 and / or at least parts of the roll 03 carrying trolley 11 or AGV 11 are pivotally mounted about a vertical axis. In this way, said pivotally mounted components, but 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 Roll 03 in a possible imbalance, for example by a few degrees possible, so that the receiving means 07 can optimally engage in the axial direction in corresponding openings of the roller 03. In addition, rollers 03, which arrive in a certain position at the transfer point 12, are pivoted by means of the pivoting device 59 by, for example, at least 180 °, whereby a compensation of previously incurred errors is possible. Such errors can take place, for example, at an unpacking station 61, if a roll 03 is misdirected from the start filed and unpacked. 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 a preferred embodiment, the pivoting device 59 is at least partially designed as a turntable 59 or turntable 59 and is in operative connection with a drive. Preferably, the pivoting device 59 at least one externally and / or internally toothed gear and is mounted on rolling elements and / or sliding body. The drive can be for example a hydraulic drive or preferably an electric drive motor, which is more preferably position-controlled. The swiveling device 59 is preferably arranged and designed in such a way that by means of the swiveling device 59 a part of the second transporting means 52 designed as a rail 52 can be pivoted about a preferably vertical axis relative to a remaining part of the second transporting means 52, preferably by at least 180 °.

A rotation of a rotated by 180 ° oriented roller 03 can take place, for example, by the roller 03 is first introduced in its twisted orientation on the transfer point 12 in the intermediate storage 51 and then analogous to the Described above is transferred to the trained as a transfer and / or lifting table 09 second transport 52. By means of the corresponding pivoting device 59, for example a turntable 59 arranged as part of the transfer and / or lifting table 09, the roller 03 is then pivoted through 180 °. For this purpose, the pivoting device 59, which is initially in a first pivot position, rotated by 180 °, so that it is located in a second pivot position. The first pivot position and the second pivot position thus preferably differ by a 180 ° about a vertical axis pivoted arrangement of the pivoting device 59 It is preferred reasons of space, the catcher 58 pivoted so that, depending on the previous orientation, after the pivoting operation, the capture device 58th between the roller 03 and the paster 59 is arranged. The transfer and / or lifting table 09 is now or previously moved to a transfer position 54, from where the now properly oriented roller 03 is moved into an empty storage position 53. Once the transfer and / or lifting table 09 is empty, the corresponding pivoting device 59 and thus also the catching device 58 is again pivoted through 180 °, ie brought from the second pivot position back into the first pivot position. Now or at a later time, the properly oriented roll 03 of the storage position 53 can be removed and fed to the correctly oriented transfer and / or lifting table 09, to then be moved into the receiving and / or delivery area of the roll changer 01. In particular, in this procedure, the roller 03 is transferred from the second transport means 52 to a storage position 53, while the pivoting device 59 is in the second pivot position and the roller 03 is transferred from the long-term storage position 53 to the second transport 52 while the pivoting device located in the first pivotal position.

It is of course also possible to store misaligned roller 03 in a storage position 53, to pivot the pivoting device of the empty transfer and / or lifting table 09 by 180 ° about the vertical axis from the first pivot position to the second pivot position, the roller 03 again to relocate the transfer and / or lifting table 09 and then the pivoting device 59 of the transfer and / or lifting table 09 together with the wrongly oriented roller 03 to pivot about 180 ° or about another vertical axis and thus to pivot the pivoting device 59 from the second pivot position back into the first pivot position. As a result, the roller 03 is preferably oriented correctly and arranged between the roller changer 01 and the catching device 58. In particular, in this procedure, the roller 03 is transferred from the second transport means 52 to a storage position 53, while the pivoting device 59 is in the first pivot position and the roller 03 is transferred from the long-term storage position 53 to the second transport 52, while the pivoting device located in the second pivotal position.

Rollers 03 are preferably arranged at the latest at the unpacking station on first transport means 11 on which they are transported to the intermediate storage 51 and on which they are arranged in the intermediate storage 51 in storage positions 53 and on which they are moved to the transfer and / or lifting table 09 and from which they are lifted by means of the receiving means 07 of the roll changer 01.

At least two are preferred such memory positions 53 are arranged and more preferably more than two memory positions 53. A plurality of memory positions 53 are preferably arranged side by side in a direction parallel to a direction in which the second transport means 11 is movable. The at least one shut-off device 14 is preferably designed such that it physically prevents persons from passing the shut-off device 14. Preferably, the at least one shut-off device 14 is not designed exclusively as a marking and / or inscription and 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.

In a preferred embodiment, the roll changer 01 is distinguished by the fact that the operating device 18 of the roll changer 01 is structurally separate from the roll changer 01, preferably at the outside of the security area 17 and / or at a distance of at most 1 m from the boundaries of the security area 17 lying place.

In a preferred embodiment, the roll changer 01 is further characterized in that at least one roller 03 is arranged or can be arranged on a first transport means 11 and that the first transport means 11 is arranged or can be arranged on the second transport means 52 arranged in the security area 17 and further preferably that arranged on the second transport means 52 first transport means 11 and / or rollers 03 are arranged pivotably about a vertical axis by means of the pivoting device 59.

In a preferred embodiment, the roll changer 01 is further distinguished by the fact that at least part of the pivoting device 59, both with and without roller 03 disposed on the second transporting means 52, is arranged to be pivotable around the vertical axis by at least 180 °.
