Is not a material roll 08 with the required minimum weight (and otherwise no correspondingly heavy object), so there is a signal at the output of the sensor, which is an unloaded state of the support device 18 or the receiving means 19 ; 21 signaled. Will be a roll of material 08 (or another item 08 ) with the minimum weight in the range of the switching means 53 ; 63 When switched on, the switching state changes with the consequence that a signal representing a loaded state is present at the output.

B. as a lift table 17 trained lifting device 17 spatially fixed to the ground, but an upper part 18.1 ; 18.2 a possibly vertically multi-part constructed carrying device 18 against an underlying part 18.1 or a recording medium 19 ; 21 on the carrying device 18 in the above sense horizontal in a front and a rear work position can be brought. As a result, in both cases, that of the carrying device 18 encompassed and / or arranged on this recording means 19 ; 21 into the aforementioned front and rear working position - once, for example, indirectly via the movement of the entire transfer device 14 and in the other case directly by its relative movement relative to or part of the carrying device 18 ,

The mentioned control means 29 ; 31 ; 32 ; 36 ; 41 can in principle each case by one or more circuits, for. As hardware circuits, by one or more implemented in computing means program routines or as a combination of such circuits and program routines. It can in the respective control means 29 ; 31 ; 32 ; 36 ; 41 several, if necessary into each other are provided and / or implemented cross-circuits and / or routines for processing different processes.

The automated or at least partially automated removal process for taking a currently still on the roll carrier 07 worn roll of material 08 may, for example, as a result of the control means 32 the role carrier 07 initiated command or as a result of a by operating personnel via preferably a user interface 54 on the roll carrier 07 , or possibly indirectly at the helm 37 the removal device 13 or manually triggered command at the control desk. If the material roll to be removed 08 supporting frame 56 the role carrier 07 not fundamentally arranged fixed to the frame and / or a removal position of the roll of material 08 or of the supporting frame 56 deviates from the operational winding position, the support frame 56 or the material roll carried thereby 08 as a result of the signal triggering the sampling process - for example by the control means 32 the role carrier 07 controlled - spent in a discharge position. If the removal process has been triggered and is possibly the formerly frame-fixed or appropriately aligned support frame 56 or the material roll carried thereby 08 in his or her discharge position, then -. B. by the control means 32 the role carrier 07 a release signal, generated and, for example, the control means 36 the removal device 13 supplied or at least at an output of the control means 32 the role carrier 07 provided. The release signal has the significance that the roll of material 08 is ready for removal, ie, for example, is in the requisite extraction situation.

The preceding steps are for example the actual, for example by the control means 36 the removal device 13 preceded by a controlled removal process and deliver the ready-to-standby signal only the initiation of the withdrawal process start signal, to which the actual removal process is started (see, for example, in the divided for better readability figure 7a and 7b) ,

For example, the control means controlling the removal process 36 continuously or cyclically checks whether there is a signal for readiness for collection on the input side (in 7a for example with process step P1 designated). Once in the process step P1 the readiness for acceptance is affirmative, the process steps required for the removal are processed, the number and / or sequence of the required process steps depending on the equipment of the removal device 13 and / or configuration of the process management may vary.

The removal process comprises, for example, at least one determination of the roll diameter (process steps P2 or. P3 ). This can be done either by a measurement (process step P2 ), for example via the control means 36 the removal device 13 is triggered and / or carried out using a diameter measuring device set forth above. Alternatively, the diameter may be made by reading in corresponding diameter-related data, for example in the control means 32 the role carrier 07 present and z. B. via the signal connection 38 be transmitted.

In an advantageous embodiment, both a measurement (process step P2 ) as well as reading in (process step P3 ) already present diameter data, the two results in a subsequent step (process step P4 ) are compared. If the two values deviate more than permitted from one another, for example by more than one absolute, relative or percentage tolerance value, preferably predefinable and changeable, then an error message and / or an abort of the (semi-) automatic removal process takes place (process step P5 ). For example, a value for a maximum tolerable deviation between the two determined diameter values can be defined as a tolerance, which, for example, depending on the accuracy requirements and / or the possibilities of the measuring device used, amounts within a range of less than 100 mm, advantageously in the range of 80 mm to 5 mm, in particular between 50 mm and 5 mm. A larger value for the tolerable deviation could possibly lead to disturbances in the further process chain and too small a value to an undesired frequent abort in the process step P4 to lead. For example, one of the two values or, advantageously, an intermediate value formed by averaging can be guided as the value to be processed for the roll diameter.

After a value for the roll diameter has been determined via one of the alternatives or preferably after the positive comparison, in an advantageous process variant this value becomes the required vertical position required for lifting the carrying device 18 determined (process step P7 ). This happens, for example, taking into account the geometric conditions such. B. the vertical relative position of the support device 18 and in Abgabeposition located support frame 56 the role carrier 07 , in particular the effective center axis.

Instead of or preferably in addition to this, in a particularly advantageous process embodiment, after a value for the roll diameter has been determined via one of the alternatives or preferably after the positive comparison, an expected roll weight is calculated from the value to be taken into account for the roll diameter (process step P6 ). This happens z. B. taking into account, for example, the machine control 29 , the control means 41 the input-side roll carrier 07 or the control means 32 the output side roll carrier 07 originating roll data (eg for data on the printing substrate and / or on the sleeve).

After the expected vertical position is determined as the desired vertical position and / or the value for the roll diameter, the lifting of the support device starts 18 (see, for example, also 3 With 4 ), z. B. by appropriate driving of the drive means provided for this purpose 24 (Process step P9 ). The lifting takes place, for example, in a control loop in which the current vertical position is compared with the expected vertical position continuously or cyclically (process steps P10 or. P11 ). The lifting takes place in this control loop z. B. until the expected vertical position is reached and is stopped at the latest when reaching the expected vertical position (process step P12 ).

In a preferred embodiment, in which, for example, a measure of the weight of a by the lifting device 17 currently taken load-supplying measuring device is provided and / or during the lifting a weighing by the support device 18 When the load is absorbed, a weight increase determined in relation to the unloaded state is continuously or cyclically determined during lifting with the expected weight of the roll of material 08 compared (process step P13 or. P14 ). The value for the expected roll weight can in principle be read in or entered beforehand, but advantageously determined via the above-mentioned steps.

In the preferred embodiment of the removal process including a monitoring of the load absorption by the above-mentioned process step P13 and P14 is during the lifting process (process steps P10 ; P11 ) monitors not only the achievement of the expected vertical position, but in parallel also achieving a weight gain corresponding to the expected roll weight. The lifting is then until the - z. B. determined from the roll diameter - vertical position or the expected roll weight corresponding weight gain is reached and is already stopped with the presence of one of the two criteria (process step P12 ). In a modification, however, the presence of both criteria may be a condition for the continuation of the sampling process. In each case tolerable deviations are preferably provided within which the corresponding condition is still regarded as fulfilled or can be.

Basically, after the first time by reaching the target lift height formed by the expected vertical position and / or the expected weight gain stopping (process step P12 ) by the extraction process controlling control means 36 the process continues with the next process step and z. B. a release signal for the introduction of a by the roller carrier 07 generated and to the control means 32 the role carrier 07 be transmitted (process step P17 ). Preferably, however, at least in the case of the abortion as a result of the achieved weight gain, before the next step and in particular before the release after at least the first stop, a time interval, for example of at least 50 ms, preferably at least 150 ms, awaited and after its lapse the value resumed for weight gain. If there is a positive difference between the expected deviation and the weight increase hitherto carried out during the lifting, compared with the previous measurement, a gradual raising and waiting takes place until after the time interval has elapsed no change in value has taken place and / or the difference is in a - for example definable - tolerance range. In the case of this embodiment variant, the generation and transmission of the release signal for the downsizing takes place hereafter.

The "Abachsen" can - depending on the design of the support mechanism on the roller carrier 07 - be given in principle by every process through which the roll of material 08 from the roll carrier 07 or its supporting frame 56 is released and then removed freely. For example, this can be achieved by moving two clamping cones engaging in the roller sleeve from the front side or by releasing two sections of a continuous shaft or axle protruding from the roller sleeve or two end stub shafts or axle stubs from a suitably designed mounting on the roller carrier 07 be feasible. It may be the "Abachsen" to the opening of any arbitrarily designed holding system, so that the roll of material 08 then free from the roll carrier 07 is and on the recording medium 19 ; 21 vertically and / or horizontally.

After passing through the roller carrier 07 a Abachsen is done, ie as a result of z. B. the control means 32 the role carrier 07 caused Tragarmbewegungen, previously in the roller sleeve frontally engaging cones from the frontal alignment of the roll of material 08 are moved out, which is the removal device 13 or their drive means 24 ; 27 controlling control means 36 the release is reported. This happens, for example, by the control means 36 the removal device 13 from the control means 32 the role carrier 07 a corresponding signal is supplied. The roll of material 08 is now free on the carrying device 18 , In particular on the encompassed by this or arranged on this receiving means 19 ; 21 on.

Before through the control means 36 the removal device 13 a lowering of the support device 18 is initiated, is checked for the presence of the Abachsprozess positive confirming enable signal. This check can be carried out continuously or cyclically (process step 18 ). A not completely or not properly performed Abachsen could get caught and tilting the roll of material 08 and thereby dangerous situations and / or damage to the roll of material 08 to lead.

Only after completion and / or approved by Abachsprozesses approval starts z. B. the lowering of the support device 18 , z. B. by appropriate driving of the drive means provided for this purpose 24 , Lowering (process step P19 ) takes place, for example, until a lower end position, z. B. via a corresponding sensor 48 monitored situation, is reached. The lowering can be done via a correspondingly established control loop - comparable to z. B. for lifting - done.

In the version with horizontally displaceable transfer device 14 occurs before the lifting step (process step P9 ) of the carrying device 18 or the receiving means 19 ; 21 nor a horizontal method of transfer device 14 (Process step P8 ) From a release or rest position in one of the material roll to be removed 08 working position (see, for example, also 2 With 3 ). Accordingly takes place - depending on structural requirements - before or after lowering the support device 18 or the receiving means 19 ; 21 a horizontal displacement of the transfer device 14 (see, for example, also 5 With 6 ) from the working position required for the removal into the delivery or rest position (process step P20 ).

In a configuration of the removal process which is particularly advantageous in terms of safety and therefore to be preferred, the process step takes place before the lowering and / or the horizontal displacement P19 ; P20 still checked, whether actually a load, as for example, at least by a material roll 08 would be given on the carrying device 18 rests on (process step P15 ). This takes place, for example, by way of a sensor device which is triggered mechanically by the applied weight force 53 ; 63 , z. B. as in particular binary switching device 53 ; 63 , as mentioned above, for example, and is set forth in more detail below in advantageous embodiments. In this embodiment variant of the removal process is prior to lowering and / or possibly horizontal displacement of the support device 18 nor the presence of the load, in particular the switching state of the sensor device 53 ; 63 checked and in the case of a negative result, ie no adequate load, a fault message is issued and / or the (partially) automatic removal process is aborted if necessary (process step P16 ).

As already above for the execution of the removal device 13 explicitly emphasizes, is also for the removal process, the horizontal displacement of the support device 18 or of the recording medium encompassed by the latter and / or arranged on it 19 ; 21 by relocating the takeover facility 14 also apply to the process sequence that a horizontal shift of the receiving means 19 ; 21 both indirectly by relocating the takeover facility 14 , as well as directly by relocation on the example in this case spatially fixed transfer device 14 he follows.

After the roll of material 08 or the material roll 08 carrying receiving means 19 ; 21 vertically in the lower layer and possibly horizontally in the farther from the roll carrier 07 spaced location, z. B. in the discharge position, spent, the removal process can be completed per se.

Possibly. However, before the end of the process and / or before a release of the sampling device 13 for the possibility of re-running in a process step, not shown, a check on whether the roll of material 08 from the recording medium 19 ; 21 is removed and / or whether an unloaded receiving means 21 on the carrying device 18 is available. Such a check is, for example, via the evaluation of the switching state of a sensor device already mentioned above 53 and / or by a presence of a receiving means 21 on the carrying device 18 cognitive sensor effect.

After the takeover facility 14 in the dispensing or rest position - which in principle can be the case even without horizontal displacement - can from the roller carrier 07 removed material roll 08 from the withdrawal facility 13 , z. B. from the transfer device 14 or in particular of the carrying device 18 to be removed.

The removal can in a first embodiment, for example by unloading the support 18 or the recording medium covered by this 19 respectively. Here, the receiving means 19 in the simplest case rigid and immobile only serve to avoid rolling, wherein the roll of material 08 manually moved over the rolling resistance or by a lifting device 17 recorded and lifted.

In an advantageous embodiment of the first embodiment shown here, this is the roll of material 08 carrying receiving means 19 with a deactivatable rolling obstacle and / or as a particular tilting or swiveling loading means 19 executed (see eg 11 ). Preferably, a drive means 57 provided by which the rolling obstacle deactivatable, ie out of action, and / or the loading means 19 can be brought from a holding position in a discharge position. The tilting or swiveling loading device 19 is z. B. groove-like and about a parallel to the longitudinal extent of the groove extending pivot axis pivotally mounted on the support device 18 stored. As drive 57 can be a drive motor 57 or advantageously a pressure-medium-actuated cylinder-piston system 57 be provided. In an illustrated embodiment is thus a tilting device with a by a drive means 57 tiltable or swiveling loading means 19 intended.

It is preferable for the position monitoring of the rolling obstacle and / or of the tiltable or pivotable loading means 19 one the receiving means 19 provided with regard to its operating condition monitoring sensor. This includes, for example, at least one sensor 58 ; 59 , by which the taking of the holding position or the unloading position is recognizable. Preferably, it comprises both a sensor 58 , by which the receipt of the holding position is recognizable as well as a sensor 59 , by which the receipt of the unloading position is recognizable. The sensor 58 ; 59 can basically be based on mechanical, optical, capacitive or magnetic measuring principle based, but is preferred here as an inductive proximity switch 58 ; 59 educated.

The carrying device 18 , in particular the receiving means 19 , preferably comprises the above, the absence of a roll of material 08 Cognitive sensors with the corresponding sensor device 53 , The sensor device 53 can in principle be designed and arranged arbitrarily in the way, so that their actuating means 61 in the empty state of the receiving means 19 the envelope of a aufzusetzenden on this roll of material 08 penetrates. In this case, the arrangement is chosen, for example, so that this for material rolls 08 of any diameter which is within a permissible and permissible diameter range for the removal.

In an embodiment shown here is the actuating means 61 for example, in the manner of one in the roll of material 08 facing cargo space projecting into the switching means 61 designed and preferably against an actuation, ie a displacement of the reel surface, biased in the manner mentioned above in the direction occupied in the unloaded state or working against a significant mechanical resistance. The actuating means 61 is here formed, for example, by a splayed in the unloaded state in the hold tab, which bent back springing into the hold and / or working against a spring medium or directly to a sensor 62 , z. B. a different between two switching states switching means 62 acts.

That by the actuating means 61 switched switching means 62 can in principle be designed mechanically, optically, capacitively or magnetically acting. Preferably, it is designed as a proximity switch, in particular as an inductive proximity switch, which by approaching the actuating means 61 or an optionally coupled Wirkverlängerung at the output of a state representing an unloaded state changes to the loaded state representing switching state.

The switching state of the sensor device 53 or the sensor 62 can then z. B. in the manner indicated above in such a way in the removal process that, for example, no Abachsen the roll of material 08 and / or not lowering or retracting the carrying device 18 takes place without a signal representing the loaded state being present and / or that the removal process does not have to be restarted as long as a signal representing a loaded state is present.

As already explained above, in an advantageous development (eg. 12 to 17 ) as receiving means 21 a means of transport 21 provided by which the roll of material 08 receivable and along a transport path without the need to transfer from the support device 18 down to a transfer position 22 (eg indicated in 13 ) or even a storage position 23 in a several material rolls 08 receiving storage facility 77 (eg indicated in 1 ) is transportable. The movement along the transport path can in principle be carried out by any means, the means of transport 21 from the carrying device 18 Drive means moving to a defined and / or definable location. This can be z. B. by self-propulsion of the receiving means 21 even in the way of one AGV (automated guided vehicle), through a receiving means 21 promotional AGV or by an arranged in the transport path and the one or more passive means of transport 21 promotional conveyor system be realized.

In a preferred embodiment, the one or more as a means of transport 21 trained receiving means 21 driving drive device designed as a particular rail-mounted underfloor conveyor system. In this case, for example, a traction means, for. As a chain, by a drive means 76 , z. B. a transport path fixed drive motor 76 , driven and coupled to the traction means of transport 21 moved on the relevant transport route. Preferably, the means of transport is 21 optionally coupled to the traction means and decoupled from this. The means of transport 21 is preferred as guided on rails trolley 21 educated.

The carrying device 18 includes, for example, a section of the route 74 (see eg 13 ) on which the means of transport 21 is movable.

Basically, regardless of the design of the drive device, but in particular of advantage with its design as a rail-mounted underfloor conveyor system, is also for the execution of as a means of transport 21 carried out recording medium 21 a sensor with a sensor device 63 provided by which for a on the support device 18 - in z. B. a working position to be taken on this - placed means of transport 19 the absence of a roll of material 08 (or another item 08 ) with z. B. the above minimum weight is recognizable.

The sensor device 63 includes one with the means of transport 19 entrained actuator with a preferably mechanically actuated actuator 64 and a relative to the support device 18 spatially fixed sensor 66 , in particular a switching means to be switched by the actuating device 66 ,

That at the means of transport 19 entrained actuating means 64 is designed and arranged so that it in the unloaded state, ie in the empty state of the receiving means 19 , the envelope of a aufzusetzenden on this roll of material 08 penetrates. The design and arrangement is, for example, such that this is for material rolls 08 of any diameter which is within a permissible and permissible diameter range for the removal.

The actuating means 64 is preferably against actuation, that is, a displacement of the reel surface, biased in the manner mentioned above in the direction of the unloaded state carried out or operating against a significant mechanical resistance. For example, it requires for the actuation, that is to say for displacement from a position representing the unloaded state into a position representing the loaded state, a weight or a resistance force to be overcome of, for example, at least 1 N, preferably still significantly more, e.g. B. at least 10 N, in particular at least 20 N or even more than 30 N.

The by the actuating means 64 the actuator to be switched sensor 66 can in principle be based on a mechanical, optical, capacitive or magnetic measuring principle switching means 66 be executed, but is preferred here as an inductive proximity switch 66 formed, which by approaching the actuating means 64 or an optionally coupled Wirkverlängerung at the output of a state representing an unloaded state changes to the loaded state representing switching state.

The sensor 66 is so corresponding to the transport 21 entrained actuator on or in the region of the support device 18 arranged so that when in working position on the support device 18 located receiving means 19 by a change in position of the actuating means 64 from the unloaded state position to the loaded state position at the output of the sensor 66 a change in the switching state of the unloaded state switching state is effected in the loaded state state switching state.

For example, as an actuating means 64 at the means of transport 21 an actuating rod 64 stored, which z. B. against a spring element 67 , For example, a spring 67 , works and in the unloaded state in the manner outlined above, the envelope of a roll of material to be deposited 08 penetrates. When actuated, ie in case of load, this operating rod occurs 64 itself or a coupled thereto and moved by this switching element 68 in switching contact with the support device fixed switching means 66 such that its switching state changes from the state representing the unloaded state to the state representing the loaded state.

In the present and advantageous example of the actuating device, this actuating rod acts 64 not even on the switching means 66 but a - preferably via a switching path of the actuating means 64 in a larger movement of the switching means 66 translating gear - with the operating rod 64 coupled switching element 68 . which, for example, as a switching flag 68 is formed and / or designated.

The one with the sensor 66 cooperating part of the actuator, e.g. B. the relevant part of the actuating means 64 or the switching element 68 , acts on the type and characteristics of the switching means 66 mechanical, optical, capacitive, magnetic or inductive with this together. Preferably, the actuating means act 64 or the switching element coupled thereto 68 the actuator and the sensor 66 based on inductive action together.

Instead of the spring element 67 or in addition to this - especially in the coupling with a switching element 68 comprehensive design variant - a counterweight 72 be provided, which via a pivot axis S the actuating means 64 acted upon by a force directed towards the unloaded position.

For example, is at the transport 21 an actuating rod 64 provided on at least one pivotally mounted lever 71 acts. In one - especially further than the point of application of the operating rod 64 from the pivot axis S spaced - area of the lever 71 this is as an og, with the sensor 66 cooperating switching element 68 executed or provided with such. In the area of on the other side of the pivot axis S lying lever arm, for example, the counterweight 72 provided or formed by the lever arm itself. Will the actuating rod 64 loaded, it presses the lever 71 that by his counterweight 72 is held high to the pivot axis S downward. The switching flag 68 moves thereby - the receipt of the correct working position of the receiving means 21 provided - in the detection range of the inductive proximity sensor 66 , which changes due to the switching state. The sensor 66 can do this on the rail 69 , in particular on the underfloor rail, be arranged.

In a preferred embodiment of the removal device 13 or the carrying device 18 one is the presence of a receiving agent 21 on the carrying device 18 Cognitive sensors, in particular the presence of a receiving means 21 in the correct position, eg. B. provided in the correct work situation, cognitive sensors. The sensor system comprises at least one sensor 73 (see eg 13 ), by which at least the presence, in particular the presence and taking of the desired position, for. B. the working position, the means of transport 21 on the carrying device 18 is detectable. The sensor 73 can basically be designed arbitrarily, z. B. as a on a mechanical, electromagnetic or optical stimulus the switching state changing switching means 73 , In the example here it is an inductive proximity switch 73 formed, for example, is damped when the means of transport 21 on the carrying device 18 , in particular in the work position to be detected.

The principle of the absence of a roll of material 08 on a means of transport 21 Cognitive sensor or sensor device 63 , in particular via a mechanical actuation, although at the top in a preferred connection with a removal device 13 , in particular with a stretch of road 74 on one of the withdrawal device 13 included carrying device 18 However, it is also on track sections 74 other stations, z. B. another loading, unloading or transfer station to transfer in the route network of a roller transport system. The removal device set out above 13 represents from the perspective of the roller transport viewed in this sense, at least one loading station 13 to which the roller carrier 07 role to be taken 08 by the means of transport 21 is received and thus provided for transport on the downstream transport route. The term of the roller transport system should basically only a simple, the section 74 the loading, unloading or transhipment station comprehensive and only to an adjacent transfer station reaching transport route, as well as larger systems to a complex route network with branches and / or one or more other provided in the route network loading, unloading or transfer stations and / or a warehouse.

In generalization the absence of a roll of material 08 on a means of transport 21 recognizing sensor or sensor device 63 this can be provided for any section of a roller transport system, for which the unambiguous answer to the question of the loading state of the means of transport 21 For example, of safety and / or control technology relevance. This may be next to or in place of the described application on one of the transfer devices 12 assigned station of the route network in the area of another station in the route network of a roller transport system be useful to apply, where a loading or unloading of means of transport 21 with material rolls 03 ; 08 takes place and / or is required.

Above explanations on the design of the sensor device 63 are thus to be generalized to sections of other stations to be transferred with the proviso that in place of the section 74 comprehensive carrying device 18 generalizes the section of the route 74 more comprehensive and that Mode of Transport 21 as a kind of road section serving ground section 18 occurs, with the proviso that of the section of track 74 assigned background to the location of the support device 18 occurs and the sensor 66 thus with respect to the subsurface is fixed in space.

The sensor device 63 can then in general on the output side with the further transport on the transport route controlling control means, such as a drive control for the transport 21 on the stretch of track 74 and / or an adjoining transport section driving drive means, and / or - as in the above example - with a to be performed by the loading, unloading or transfer station process or process step controlling means 36 in signal connection.

The above for the removal device 13 and for the removal process and for the execution of the recording medium used there 19 ; 21 This is - where the appropriate application does not oppose - even on an input side roller carrier 02 or the local removal of a residual role 03 ' transferred to.
