For the safe and / or realization of an automated or at least semi-automatic removal, the removal device 13 comprises at least one a measure of a vertical position of the role to be taken 08 in the bale, especially within an axially considered middle third, preferably in the center, the bale on the bottom or top, supplying measuring device. Preferably, the vertical position supplying measuring device is formed by a distance measuring device, which in principle can be based on any suitable for the distance determination optical or mechanical measuring systems. For example, it may be based on an optical or mechanical measuring system, which measures a distance between a roller carrier frame-fixed and / or a space-fixed sensor 49 (in FIG. 11 and FIG. 15) encompassed by the distance measuring device

Roller shell outer surface allowed. In the present and here preferred case, the sensor 49 encompassed by the distance measuring device is formed by a laser distance sensor 49 whose viewing direction is preferably aligned radially with respect to the position of the roller axis present during the measurement.

The measuring device delivering the vertical position stands with correspondingly arranged data processing means controlling the processes for the roll removal

Control means 36 in signal connection, by which a change between a present at a given time or in a given operating situation starting position and a current position of the roller 08 can be determined. or is determined.

Depending on the web width and possibly the weight of the roll to be taken 08, this depends on the weight in the middle more or less strong. In addition to the deflection of the roller 08 itself can also be other factors, such as

For example, a weight-related elastic yielding of parts of

Roller mount, for which, compared to the theoretical position of the roller 08 at the measuring location, which it would assume with complete rigidity of roller 08 and bracket,

divergent situation be responsible. The bending and possibly other factors should be summarized below by the formulation of a "sinking" of the roller 08 in the region of the measuring location

Railway width-dependent and can be determined empirically. In this case, the sinking in the central region of the roller 08 for rollers 08 a web width of 2,400 to 2,600 mm, for example, 3 to 7 mm, in particular 4 to 6 mm are assumed. Particularly suitable for the correlation between roller 08 and expected sinking depth E, the roller volume V has been found. Values, e.g. B. sinking depths E, for the expected or assumed sinking (for the location of the measurement) depending on the web or roll bale width or preferably of roll volume V.

For example, in the control means 36, z. B. tabular or as a functional context Z, held.

As a criterion for the role to be taken 08, for example, serve their diameter, which determines, for example, explained below, z. B. over

Roll carrier data can be determined or measured.

If the receiving means 19; 21 (18 is the support means) raised by the lifting device 17 from below against the roller 08, wherein, for example, the presence of a roller 08 is registered in the manner outlined below, the roller 08 after the first touch upon further lifting of the receiving means 19; 21 possibly initially slightly plastically deformed. Upon further lifting of the receiving means 19; 21, the roller 08 and located on the roller 08 measuring location is also raised, which causes a change in the previously constant distance between the sensor 49 and the measuring location on the roller 08, hereinafter also referred to as distance change. The present by the deflection and possibly other factors sinking of the roller 08 is by the

Lifting movement of the receiving means 19; 21 gradually decreases until, ideally, the total roll weight is taken up and subsidence is substantially eliminated when the value of the distance change reaches the expected value for sinking. In principle, the lifting movement can take place until the theoretically assumed deflection compensation is reached, that is, continuously. In a preferred embodiment, the lifting of the receiving means 19; 21, however, successively in breaks, z. B. 1 to 5 seconds, interrupted steps. This allows a more accurate positioning of the roller 08 done.

In order to avoid that the roller 08 is raised too much, for example, because the deflection is less than assumed or as the empirical values for the still aufgeachste role 08 may suggest, in an advantageous embodiment, the movement of the receiving means 19; 21 for the roller to be removed 08 to a maximum lifting height for the receiving means 19; Be limited 21 or be. The value for the maximum lift height is based on a roller diameter of

taking away roller 08 on the one hand and on the vertical position of the roller axis of the roller located in the removal position 08 on the other. In this case, the roll diameter, for example, from operating data, eg. As the winding length of the roller carrier 07, or from a measurement in example set forth below manner be obtained by a suitably trained device. The height of the roller axis in the picking position is known, for example, or can be obtained from control or drive data of the roller carrier 07.

For example, the lifting in the role removal can be limited to a maximum lifting height, the z. B. using a determined via the sensor 49

Approximate value for the diameter or radius of the roll to be taken 08 is obtained. The approximate value for the radius, for example, by the difference of the known vertical distance between the position of the theoretical

Rotation axis in the removal position and the sensor 49 and the distance measured in the radial direction of the roller 08 between the sensor 49 and the outer periphery of the roller 08 is formed. This corresponds to z. B. one compared to the real value by the strength of the actual sinking of smaller value. This approximated radius results Thus, from the difference of the distance between the theoretical roller axis and sensor 49 and the distance between the sensor 49 to the roller 08. About the thus estimated diameter and the resulting volume can be determined with the above-mentioned relationship Z expected sinking and this a maximum lifting height can be fixed For example, as a factor greater than one, z. B. with two, multiplied value of sinking, resulting from the z. B. known roll width and the roll volume V results, which is determined by the approximate value for the radius or can be determined.

To determine the roll diameter can in an advantageous embodiment of the removal device 13 is a measure of the diameter of the still by the

Roller carrier 07 carried and delivered in the following to be taken material roll 08 device, in particular sensor device, hereinafter also referred to as a diameter measuring device. These

Diameter measuring device may instead, but preferably in addition to a z. B. a data interface leading signal connection to an information on the current diameter value having data source may be provided which z. B. are provided in the control means 32 of the roller carrier 07 and / or be and, for example, using original role data and the current

Settlement length are determined and / or will be.

The diameter measuring device can basically be used on any, for the

Diameter determination suitable optical or mechanical measuring systems based. For example, the abovementioned measuring system provided for determining the distance with the spatially fixed sensor 49 (see, for example, also FIGS. 11 and 15) can also or instead be used to determine the roll diameter, which then has a known position of the material roll axis Distance measurement between the roller carrier frame fixed and / or fixed space sensor 49 and the

Roller shell outer surface determine an approximate value for the roll diameter lets or determines. Preferably, the expected value for the sinking is subtracted from the thus obtained approximate value in order to obtain an improved approximation value for the diameter.

In an advantageous development, in addition or possibly as an alternative to the above-described determination and evaluation of sinking, the removal device 13 comprises a measurement device for measuring the weight of a load currently received by the lifting device 17, hereinafter also referred to as weighing device, and / or one a measure of the current vertical position of the support means 18 and the receiving means 19; 21 supplying device, hereinafter also briefly as

Height measuring device called.

In this case, the measuring device relating to the weight provides, for example, a measure of a weight increase brought about by the receptacle on the carrying device 18 or the receiving means 19 relative to the unloaded state.

The weighing device comprises z. B. at least one force sensor 46 and possibly a the electrical signals of the at least one force sensor 46 evaluating evaluation. Preferably, several, in particular at least three, z. B. four, force sensors 46 are provided. The force sensor 46 is z. B. executed as a so-called. Load cell 46 and includes a force absorption, for example, in the manner of a

Spring body, a piezoelectric element or possibly resistive may be formed. A weighing result is determined by taking into account and evaluating the signals of all the force sensors 46 included in the weighing device.

The one or more force sensors 46 of the weighing device are in the structure between the material roll 08 receiving receiving means 19; 21 and the the

Transfer device 14 supporting substrate arranged. Although the Force sensors 46 between the substrate and base 16, between two parts of a possibly vertically multi-part substructure 16, between the base 16 and the lifting device 17, between the lifting device 17 and the support means 18 or between the support means 18 and the receiving means 19; 21 could be arranged, these are preferably between two parts 18.1; 18.2 of the vertically multi-part carrying device 18 is arranged (see, for example, Fig. 1 1). For example, in each case in the axial direction A of the roller carrier 07 spaced-apart force sensors 46 in the production direction T are spaced apart between the two parts 18.1; 18.2 of the support device 18, z. B. a support frame 18.1 and a receiving platform 18.2 arranged.

The height measuring device can be of any desired design, one covered

Movement distance or a position on a predetermined route reproducibly detecting measuring system 47 be. For example, the measuring system 47 may be provided by a device for, for example, laser-based distance measurement between a roller carrier or fixed space point and a point of the receiving means 19; 21, be carried out by a magnetic position measuring system or by a mechanical measuring system 47. In the example, the measuring system 47 is executed because of its robustness and the possibility of its obstruction in the lifting device 17 as an incremental cable-way measuring system 47, in which a z. B. spring-loaded rope is raised while the increments of the revolutions of the cable drum are evaluated. One end of the cable path measuring system 47 is fixed in respect of the ground and the other end fixed to the support means 18 and moved vertically with this.

Preferably, two such measuring systems 47 are provided horizontally spaced from each other and provide redundant values for the current altitude, from which, for example, the mean value is formed and used. If the individual values deviate from one another by more than a definable tolerance amount, for example, a fault message and, if appropriate, a cancellation of the currently running movement process take place. As an alternative to an external measuring system 47, the vertical position of the

Carrying device 18 supplying device also comprise a measuring system 47 integrated in the drive of the lifting device 17. In a development in which the

Lifting device 17 can be driven by a position-adjustable drive means 24, the device delivering the current vertical position of the support means 18 may be formed by the actual value of the drive means 24 issuing and / or evaluating output and / or evaluation. In this case, it may be advantageous for safety reasons if in addition a redundant external measuring system 47 is provided.

Basically, a lower end position of the vertically displaceable support means 18 via the measuring system 47 set out above or one of the drive internal

Alternatives can be determined. In a further development, however, a sensor 48 is provided by which the receipt of a lower end position by the support means 18 can be detected. The taking of the lower end position detecting sensor 48 may be basically formed arbitrarily, for. B. as a mechanical, electromagnetic or optical switching means 48. In the present example, it is designed as an inductive proximity switch 48 which is attenuated when the vertically movable support means 18 is in the lower end position. In this case, the sensor 48 - such. As indicated in Fig. 1 1 - spatially fixed and directed towards the support means 18 or at the

Transfer device 14 arranged and directed to a space-fixed boundary.

For the o. G. Case that the transfer device 14 is designed to be horizontally displaceable, a sensor may be provided in an advantageous embodiment, which at least one respect. The direction of movement in the direction of roller support 02 front and a rear working position of the horizontally displaceable transfer device 14 can recognize. For this purpose, for example, a sensor 51 is provided, through which their receipt of a front working position, for. B. their location below the roll of material 08 in

Removal position is detected, and a sensor 52 through which their ingestion a rear working position, z. B. a provided for dispensing the roll of material 08 and further spaced from the roller carrier 02 position, z. B. dispensing position, can be determined. The respective sensor 51; 52 may in principle be configured arbitrarily, for. B. as a on a mechanical, electromagnetic or optical stimulus the switching state changing switching means 51; 52. In the present example, it is an inductive proximity switch 51; 52 formed, which is damped, for example, when the horizontally movable transfer device 14 is located in the working position to be detected. In this case, the sensor 51; 52 fixed in space and directed towards transfer device 14 or else - such. As indicated in Fig. 10 - arranged on the transfer device 14 and directed to a space-fixed boundary.

Alternatively to the execution of the above to recognize the horizontal end positions as

Switching means 51; 52 executed sensors 51; 52 may be an arbitrarily trained, a traveled distance or a position on a given

Track be reproducibly detected measuring system provided. Thus, the two above-mentioned working situations are recognizable. For example, such a measuring system by a device for example, laser-based distance measurement between a roller carrier or fixed space point and a point of the

Transfer device 14, be carried out by a magnetic or inductive position measuring system or by a mechanical measuring system. Preferably, the

Position determination via one or more displacement measuring rods, which z. B. the

Measuring principle of magnetic switches is based.

In a preferred embodiment of the removal device 13 includes the

Carrying device 18 in the region of its upper surface facing the roll of material 08, a sensor system recognizing the absence of a roll of material 08 with a sensor device 53 - preferably triggered by a roll of material 08 to be mechanically released - by sensor device 53; 63. This works against a significant mechanical resistance and / or required for the change of the switching state an operation with a non-negligible force, such as a force that the weight, for example, at least one possibly resting

Bedruckstofffetzens exceeds. The required weight or the resistance to be overcome, for example, corresponds to at least 50 g or 0.5 N, preferably still significantly more, z. B. at least 1, 0 kg or 9.8 N, in particular at least 2.0 kg or 19.6 N. The sensor device 53; 63 or at least one of which comprises actuation means 61; 64 is in the region of the male material roll 08 facing top of the support means 18, in particular of the

Carrying device 18 comprises receiving means 19; 21 arranged so that their switching state and thus the output signal when placing a roll of material 08 with a minimum required weight on the previously free and unloaded top imperatively changed. If no roll of material 08 with the required minimum weight (and otherwise no correspondingly heavy object) placed, so is at the output of the sensor to a signal indicating an unloaded state of the support means 18 and the receiving means 19; 21 signals. If a roll of material 08 (or another object) with the minimum weight in the range of the sensor device 53; 63

When switched on, the switching state changes with the consequence that a signal representing a loaded state is present at the output. Particularly advantageous

Embodiments of the sensor device 53; 63 will be explained in more detail below (see, e.g., Fig. 12 and Figs. 16 to 18).

The above to the removal device 13 in connection with the horizontally displaceable transfer device 14 set forth is to be transferred to an embodiment in which, for example, the z. B. designed as a lifting table 17 lifting device 17 fixed to the ground, but an upper part 18.1; 18.2 an optionally vertically multi-part constructed support means 18 against an underlying part 18.1 or a receiving means 19; 21 on the support means 18 in the above sense horizontally in a front and a rear working position can be brought. As a result, in both cases the receiving means encompassed by the carrying device 18 and / or arranged on it 19; 21 in the aforementioned front and rear working position be brought about - for example, indirectly 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 support device 18th

The said control means 29; 31; 32; 36; 41 may 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. In this case, in the respective control means 29; 31; 32; 36; 41 several, possibly interlocking and / or peeling, circuits and / or routines for processing different processes provided and / or implemented.

The automated or at least partially automated removal process for removal of a currently still worn on the roller support 07 roll of material 08 can be initiated, for example, as a result of an initiated by the control means 32 of the roller support 07 command or as a result of an operator preferably via a control interface 54 on the roller support 07, or possibly indirectly at the control station 37 of the removal device 13 or manually triggered command at the control station. If the support frame 56 of the roller carrier 07 carrying the material roll 08 to be removed is not fundamentally arranged fixed to the frame and / or a removal position of the roll of material 08 or of the support frame 56 deviates from the operational winding layer, the support frame 56 or the material roll 08 carried therefrom becomes as a result of the

Removal process triggering signal - for example, controlled by the control means 32 of the roller carrier 07 - spent in a discharge position. Was the

Removal process triggered and is possibly ehedem frame-fixed or appropriately aligned support frame 56 and the material roll worn thereby 08 in his or her discharge position, it is -. B. by the control means 32 of the roller carrier 07 - a release signal generated and, for example, the Control means 36 of the removal device 13 supplied or at least provided at an output of the control means 32 of the roller carrier 07. The release signal has the significance that the roll of material 08 is ready for removal, ie

For example, is located in the required removal location.

The preceding steps are, for example, the actual, for example, controlled by the control means 36 of the removal device 13

Picking process upstream and deliver with the the readiness for removal

Only the signal representing the removal process initiates the actual removal process (see, for example, FIGS. 7a and 7b, which are respectively divided for better readability, for a first, eg.

preferred embodiment and Fig. 8a and Fig. 8b for a second, possibly alternative embodiment).

For example, is controlled by the removal process controlling control means 36 continuously or cyclically z. In a loop S1; S'1, in particular polling loop S1; S'1, checks whether there is a ready-to-pick signal on the input side (in FIG. 7a, for example, with process step P1 and in FIG. 8a with ΡΊ). Once in

Process step P1; ΡΊ the readiness for acceptance is affirmative, the process steps required for the removal are processed, wherein the number and / or sequence of the required process steps can vary depending on the equipment of the removal device 13 and / or the process control. Also, a process steps from the first and second execution combining or parallel-applying overall process can be provided by, for example, in particular for the

Decision on the correct vertical position of the carrying device or the

Receiving means 19; 21 and / or resting the material roll 08 more of the criteria from the embodiments for hedging and / or verification can be used side by side or can be. The removal process comprises, first of all, with regard to the measurement accuracy and / or speed z. B. preferred embodiment, for example, at least one determination of the roll diameter (process steps P2). This can be done either by a measurement, for example, via the control means 36 of the

Removal device 13 is triggered and / or carried out using a diameter measuring device set forth above. Alternatively, the diameter can be made by reading in corresponding data relating to the diameter, which are present for example in the control means 32 of the roller carrier 07 and z. B. transmitted via the signal connection 38.

In one embodiment, both a measurement and a read in already existing diameter data, wherein the two results are compared in an intermediate step. If the two values deviate more than permitted from each other, for example by more than one absolute, relative or percentage tolerance, preferably predefinable and changeable, an error message and / or an abort of the (semi-) automatic removal process takes place, for example In this variant, for example, one of the two values or advantageously an intermediate value formed by averaging can be guided along the roll diameter.

After a value for the roll diameter is determined via one of the alternatives or preferably after the positive comparison, this value is added to the determination

expected sinking value used directly or in a preferred process variant from this diameter value a role 08 in terms of the expected value for sinking characterizing and z. B. the input quantity in the tabular or functional relationship Z representing size formed (process step P2). Is preferred as such size -. B. using the known or over

Web carrier data determined web width - a measure of the roll volume V calculated. From the diameter value or preferably the derived therefrom size is the expected sinking depth E determined from the deposited context Z out (process step P3).

After the expected sinking depth E has been determined and, if necessary, the transfer device 14 has moved into the picking position (process step 4), the lifting of the carrying device 18 starts (see, for example, also FIG. 3 with FIG. B. by appropriate driving of the drive means 24 provided for this purpose (process step P5). Lifting takes place, for example, in a loop S2, in particular interrogation loop S2, in which the current distance between sensor 49 and roller 08 is determined continuously or cyclically (process step P6) and a change in distance beginning with the first lifting of the roller 08 is the value for the expected sinking depth Has reached E (process step P7). Latest with

If this distance change coincides with the expected sinking depth E, the lifting is stopped (process step P8).

In principle, the process can be continued with the next process step after the stopping (process step P8) by the control unit 36 controlling the removal process by reaching the correspondence between the distance change with the expected sinking depth E, and the process continues with the next process step. For example, a release signal for initiating a roll carrier 07 to be performed Abachsprozesses be generated and transmitted to the control means 32 of the roller carrier 07 (process step P1 1).

Instead of or in addition to the determination and evaluation of the change in distance according to the process steps P2 to P7 can be used as a criterion for the presence of the end position and / or the correct resting of the role and another criterion, eg. B. a weighing and / or a vertical position of the roll of material or the receiving means according to z. B. subsequently described process steps P'2 to ΡΊ 1 and / or ΡΊ4 serve. The process step P'2 goes z. B. the process step P1 with the loop S1 corresponding process step voraus ahead with the loop S'1. The removal process includes z. For example, in the second embodiment, at least one determination of the roll diameter (process steps P'2 or P'3), which differ substantially in the criteria to be tested until the differentiation takes place. This can be done either by a measurement (process step P'2), which is triggered for example via the control means 36 of the extraction device 13 and / or under

Use of a diameter measuring device set forth above. Alternatively, the diameter can be made by reading in corresponding data relating to the diameter, which are present for example in the control means 32 of the roller carrier 07 and z. B. transmitted via the signal connection 38.

In an advantageous embodiment, both a measurement (process step P'2) and a read in (process step P'3) already existing diameter data, wherein the two results are compared in a subsequent step (process step P'4). If the two values deviate more than permitted from one another, for example by more than one absolute, relative or percentage tolerance value, preferably predetermined and changeable, an error message and / or abort of the (partially) automatic removal process takes place (process step P'5 ). For example, as a tolerance, a value for a maximum tolerable deviation between the two determined diameter values can be defined, which - for example, depending on the accuracy requirements and / or the

Possibilities of the measuring device used - amount within one

Area smaller 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 process step P'4. 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 using one of the alternatives or preferably after the positive comparison Value for the roll diameter is determined in an advantageous process variant from this value, the expected required vertical position for the lifting of the support means 18 is determined (process step P'7). This happens, for example, taking into account the geometric conditions such. B. the vertical relative position of support means 18 and in the dispensing position befindlichem support frame 56 of the

Roller carrier 07, in particular the effective center axis.

Instead of or preferably additionally 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 P'6). This happens z. B. taking into account, for example, the machine control 29, the control means 41 of

Roller data carrier 07 on the input side or roller data originating from the control means 32 of the output-side roller carrier 07 (eg for data on the printing material 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 carrying device 18 starts (see, for example, also FIG. 3 with FIG. B. by appropriate driving of the drive means provided for this purpose 24 (process step P'9). 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 ΡΊ 0 or ΡΊ 1). 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 ΡΊ 2).

In a preferred embodiment, in which, for example, a measure of the weight of a currently received by the lifting device 17 load supplying measuring device is provided and / or during lifting a weighing by the

Carrying device 18 recorded load is performed during lifting a comparison with the unloaded state determined weight gain continuously or cyclically compared with the expected weight of the roll of material 08 (process step ΡΊ 3 or ΡΊ 4). The value for the expected roll weight can in principle be read in or entered beforehand, but advantageously above or below. Steps have been determined.

In the preferred embodiment of the removal process including a monitoring of the load absorption by the o. G. During the lifting process (process steps ΡΊ Ο; ΡΊ 1), process steps ΡΊ 3 and ΡΊ4 not only monitor the achievement of the expected vertical position, but in parallel also achieve a weight increase 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 ΡΊ2). In a modification, however, the presence of both criteria may be conditional on the

Continuation of the extraction process. In each case tolerable deviations are preferably provided within which the corresponding condition is still regarded as fulfilled or can be.

In principle, it is possible to achieve the desired lifting height formed by the expected vertical position and / or already after the first time

Weight gain stopping (process step ΡΊ 2) by the

Control process control means 36, the process continues with the next process step and z. B. generates an enable signal for the introduction of a roll carrier 07 to be performed Abachsprozesses and to the

Control means 32 of the roller carrier 07 are transmitted (process step ΡΊ 7).

Preferably, however, - at least in the case of the crash due to the achieved Weight gain - before the next step and in particular before release after at least the first time stopping a time interval, for example of at least 50 ms, preferably at least 150 ms, waited and resumed after the lapse of the value for the weight gain. Is now compared to the previous measurement enlarged and intolerable positive difference between the expected deviation and the previously made during the lifting

If there is an increase in weight, stepwise raising and waiting successively take place until, after the relevant time interval has elapsed, no change in value has taken place and / or the difference lies within a tolerance range that can be defined, for example. In the case of this embodiment variant, the generation and transmission of the release signal for the downsizing takes place hereafter.

Regardless of the aforementioned embodiment of the process, the "Abachsen" - depending on the design of the support mechanism on the roller carrier 07 - basically be given by any process by which the roll of material 08 from the roller carrier 07 or

the support frame 56 is released and then removed freely. By way of example, this can be achieved by moving two end faces engaging in the roller sleeve

Spannkonen or by the release of two from the roller sleeve each frontally outstanding portions of a continuous shaft or axle or two end-side stub shafts or journals from a suitably trained storage on the roller carrier 07 be effected. It may be the "Abachsen" to the opening of any arbitrarily designed holding system, so that the roll of material 08 is then free of roller carrier 07 and on the receiving means 19, 21 vertically and / or horizontally to remove.

After - triggered on the basis of one or other of the above criteria - by the roller carrier 07 a Abachsen is done, ie as a result of z. B. the control means 32 of the roller carrier 07 caused Tragarmbewegungen, previously in the roller sleeve frontally engaging cones from the frontal alignment of the roll of material 08th are moved out, is the removal device 13 and its drive means 24; 27 controlling control means 36, the release reported. this happens

For example, by the control means 36 of the removal device 13 from the control means 32 of the roller carrier 07, a corresponding signal is supplied. The roll of material 08 is now free on the support means 18, in particular on the encompassed by this or arranged on this receiving means 19; 21 on.

Before a lowering of the support means 18 is initiated by the control means 36 of the removal device 13, it is checked for the presence of the release process positively confirming the release signal. This check can be carried out continuously or cyclically (process step P12 or ΡΊ 8). A not fully or improperly performed Abachsen could lead to snagging and tilting of the roll of material 08 and thereby dangerous situations and / or damage to the roll of material 08.

Only after completion and / or approved by Abachsprozesses approval starts z. B. lowering the support means 18, z. B. by appropriate driving of the drive means provided for this purpose. The lowering (process step P13 or ΡΊ 9) takes place, for example, until a lower end position, z. B. one over 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 embodiment with horizontally displaceable transfer device 14 takes place before the step of lifting (process step P5 or P'9) of the support means 18 and the receiving means 19; 21 nor a horizontal movement of the transfer device 14 (process step P4 or P'8) from a release or rest position into a working position located under the material roll 08 to be taken (see, for example, also FIG. 2 with FIG. Accordingly, depending on the structural requirements, before or after Lowering the support means 18 and the receiving means 19; 21 a horizontal displacement of the transfer device 14 (see, for example, also Fig. 5 with Fig. 6) from the required for the removal work position in the delivery or rest position (process step P14 or P'20).

In an embodiment of the removal process which is particularly advantageous in terms of security and is therefore preferable, in a process step P13 before lowering and / or horizontal shifting, P14 or ΡΊ 9; P'20 still checked, if indeed a load, as for example, by any means

Material roll 08 would be given, rests on the support means 18 (process step P9 or ΡΊ 5). This is done for example via a mechanical way through the

applied weight force to be triggered sensor device 53; 63, z. B. as

in particular binary switching device 53; 63, (missing in list of reference numerals) as mentioned above, for example, and is set forth in more detail below in advantageous embodiments. In this embodiment of the removal process is before lowering and / or possibly horizontal displacement of the support means 18 nor the

Presence of the load, in particular the switching state of the sensor device 53; 63 checked and negative result, d. H. no adequate load, one

Error message issued and / or possibly the (semi-) automatic removal process aborted (process step P10 or ΡΊ 6).

As already explicitly emphasized above for the execution of the removal device 13, the horizontal displacement of the support device 18 or of the receiving device 19 encompassed by the latter and / or arranged on it is also for the removal process. 21 apply by moving the transfer device 14 on the process sequence that a horizontal displacement of the receiving means 19; 21 both indirectly through

Relocating the transfer device 14, as well as directly by relocation on the example in this case spatially fixed transfer device 14 takes place. After the roll of material 08 or the material roll 08 supporting receiving means 19; 21 vertically in the lower layer and possibly horizontally in the further spaced from the roller carrier 07 position, 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 removal device 13 for the possibility of re-running in a process step, not shown, a check is made as to whether the roll of material 08 from the receiving means 19; 21 is removed and / or whether an unloaded receiving means 21 on the support means 18 is available. Such a review will

For example, via the evaluation of the switching state of a sensor device 53 already mentioned above and / or by the presence of a receiving means 21 on the support means 18 recognizing sensor effect.

After the transfer device 14 is in the delivery or rest position - which in principle may be the case even without horizontal displacement - can be removed from the roller support 07 roll of material 08 from the removal device 13, z. B. of the transfer device 14 or in particular of the support means 18, are removed.

The removal can be carried out in a first embodiment, for example by unloading the support means 18 and the receiving means 19 encompassed by this. In this case, the receiving means 19 serve in the simplest case, rigid and immovable only to avoid rolling, the roll of material 08 by hand over the

Rolling resistance is moved or picked up by a lifting device 17 and lifted.

In an advantageous embodiment of the first embodiment shown here, the receiving means 19 carrying the roll of material 08 is provided with a deactivatable rolling obstacle and / or as a particularly tiltable or pivotable loading means 19 (see, for example, Fig. 12). Preferably, a drive means 57 is provided by which the

Rolling obstacle can be deactivated, d. H. can be brought out of action, and / or the loading means 19 can be brought from a holding position into a discharge position. The tilting or swiveling loading means 19 is z. B. trough-shaped and mounted about a parallel to the longitudinal extent of the groove extending pivot axis pivotally mounted on the support means 18. As drive means 57, a drive motor 57 or advantageously a

be provided fluid-actuated cylinder-piston system 57. In a

Thus, a tilting device with a tilting or pivoting by a drive means 57 loading means 19 is thus provided.

For monitoring the position of the rolling obstacle and / or the tilting or pivoting loading means 19, it is preferable to provide the receiving means 19 with regard to its operating state monitoring sensor system. This includes, for example, at least one sensor 58; 59, by which the receipt of the holding position or the unloading position is recognizable. Preferably, it comprises both a sensor 58, by which the capture of the holding position can be seen as well as a sensor 59, by which the receipt of the discharge position can be seen. The sensor 58; 59 may basically be based on mechanical, optical, capacitive or magnetic measuring principle based, but is preferred here as an inductive proximity switch 58; 59 trained.

The carrying device 18, in particular the receiving means 19, preferably comprises o. G., The absence of a roll of material 08-recognizing sensor with the

In principle, the sensor device 53 can be designed and arranged as desired in such a way that its actuating means 61 in the empty state of the receiving means 19 penetrates the enveloping surface of a material roll 08 to be placed thereon. In this case, the arrangement is selected, for example, so that this is met for rolls of material 08 of any diameter, in one for the Removal permissible and predetermined diameter range is.

In one embodiment shown here, the actuating means 61 is formed, for example, in the manner of a in the material roll 08 facing cargo space projecting into the switching means 61 and preferably against actuation, d. H. a displacement from the reel surface, biased in the manner mentioned above in the direction of the unloaded state or working against a significant mechanical resistance. The actuating means 61 is formed here, for example, by a tab spread in the unloaded state in the hold, which

bent back springing into the hold and / or working against a spring medium or directly on a sensor 62, z. B. a different switching state between two switching means 62 acts.

The switched by the actuating means 61 switching means 62 may be performed in principle mechanical, optical, capacitive or magnetic acting. Preferably, it is designed as a proximity switch, in particular as an inductive proximity switch, which changes by approaching the actuating means 61 or an optionally coupled Wirkverlängerung at the output of a state representing an unloaded state in the loaded state representing switching state.

The switching state of the sensor device 53 and 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 no lowering or moving back of the support device 18 without a laden state representing the signal present and / or that the removal process is not new start as long as there is a signal representing a loaded condition.

As already explained above, in an advantageous further development (eg, FIGS. 13 to 18), a transport means 21 is provided as receiving means 21, through which means the transport means 21 are provided Roll of material 08 and along a transport path without the need to convert from the support 18 down to a transfer position 22 (eg indicated in Fig. 14) or even a storage position 23 in a plurality of rolls of material 08 receiving bearing means 77 (eg. indicated in Fig. 1) is transportable. The movement along the transport path can basically by any

executed, the transport means 21 carried by the support means 18 to a defined and / or definable location moving drive means. This can be z. B.

by self-propulsion of the receiving means 21 itself in the manner of an AGV (Automated Guided Vehicle), by an AGV which promotes the receiving means 21, or else by an importer

Transport path arranged and the one or more passive transport 21 promotional conveyor system be realized.

In a preferred embodiment, the receiving means 21, which is designed as transport means 21 or more, is driving drive means, in 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 a coupled to the traction means transport 21 moves on the relevant transport path. Preferably, the transport means 21 is selectively coupled to the traction means and decoupled from this. The transport means 21 is preferably designed as guided on rails trolley 21.

The carrying device 18 comprises, for example, a route section 74 (see, for example, FIG. 14) on which the transporting means 21 is movable.

Basically, regardless of the design of the drive device, however

particularly advantageous with their design as a rail-bound

Unterfurfördersystem, is also for the execution of as a means of transport 21st

Running receiving means 21 a sensor with a sensor device 63rd provided by which for a on the support means 18 - in z. As a work situation to be taken on this - placed transport 21 the absence of a roll of material 08 (or other object) with z. B. the above minimum weight is recognizable.

The sensor device 63 includes a carried with the transport means 19

Actuating device with a preferably mechanically operated

Actuating means 64 and a relative to the support means 18 spatially fixed sensor 66, in particular a to be switched by the actuator

Switching means 66.

The carried on the transport means 19 actuating means 64 is designed and arranged so that it in the unloaded state, d. H. in the empty state of

Aufnahmemittels 19, the enveloping surface penetrates a aufzusetzenden on this roll of material 08. In this case, the design and arrangement is, for example, such that this is fulfilled for rolls of material 08 of any diameter which lies in a permissible and predetermined diameter range for the removal.

The actuating means 64 is preferably against actuation, i. H. a displacement of the reel surface, biased in the manner mentioned above in the direction occupied in the unloaded state layer or executed working against a significant mechanical resistance. For example, it is necessary for the actuation, d. H. for shifting from a position representing the unloaded state into a position representing the loaded state, a weight or a weighting

overcoming resistance force, for example, at least 1 N, preferably even significantly more, z. B. at least 10 N, in particular at least 20 N or even more than 30 N.

The sensor 66 to be switched by the actuator 64 of the actuator can basically be designed as a switching means 66 based on a mechanical, optical, capacitive or magnetic measuring principle, but here it is preferably designed as an inductive proximity switch 66, which by approximation of 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 arranged corresponding to the entrained on the transport means 21 actuator on or in the area of the support means 18, so that when in working position on the support means 18 receiving means 19 by a change in position of the actuating means 64 of the unloaded state of the situation in the loaded state relevant situation at the output of the sensor 66, a change in the switching state of the unloaded state

Switching state is effected in the loading state of the relevant switching state.

For example, as an actuating means 64 on the transport means 21, an actuating rod 64 is mounted, which z. B. against a spring element 67, for example, a spring 67, operates and in the unloaded state in the manner outlined above, the envelope surface of a material roll to be deposited 08 penetrates. When operated, d. H. In loading case, this actuating rod 64 itself or a coupled thereto and moved by this switching member 68 in switching contact with the support device fixed switching means 66 such that its switching state changes from the unloaded state representing in the state representing the loaded state.

In the present and advantageous example of the actuator this actuating rod 64 does not act 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 - coupled to the actuating rod 64 switching member 68, which, for example Also designed as a switching flag 68 and / or is designated.

The cooperating with the sensor 66 part of the actuator, for. As the relevant part of the actuating means 64 or the switching member 68, acts mechanically and optically, capacitively, magnetically or inductively with the latter according to the nature and form of the switching means 66. Preferably, the actuating means 64 or the switching element 68 of the actuating device coupled thereto and the sensor 66 cooperate based on an inductive operating principle.

Instead of the spring element 67 or in addition to this - in particular in the comprehensive coupling with a switching element 68 embodiment - a

Counterweight 72 may be provided, which via a pivot axis S the

Actuating means 64 with a force directed towards the unloaded position

For example, an actuating rod 64 is provided on the transport means 21, which acts on at least one pivotally mounted lever 71. In a region of the lever 71 which is at a distance from the pivot axis S, in particular further than the point of application of the actuating rod 64, this is designed as an o. G., Switching element 68 cooperating with the sensor 66 or provided with such. In the area of lying on the other side of the pivot axis S lever arm, for example, the

Counterweight 72 provided or formed by the lever arm itself. Will the

Actuating rod 64 loaded so it pushes the lever 71, which by

Counterweight 72 is held high, about the pivot axis S down. The

Switching flag 68 moves thereby - assuming the correct working position of the receiving means 21 - in the detection range of the inductive

Proximity sensor 66, which changes due to the switching state. The sensor 66 can be arranged on the rail 69, in particular on the underfloor rail. In a preferred embodiment of the removal device 13 and the support means 18 is a the presence of a receiving means 21 on the support means 18-recognizing sensors, in particular a presence of a receiving means 21 in the correct position, for. B. provided in the correct work situation, cognitive sensors. In this case, the sensor system comprises at least one sensor 73 (see, for example, FIG. 14), by means of which at least the presence, in particular the presence and taking of the desired position, for example. B. the working position of the transport means 21 on the support means 18 can be determined. The sensor 73 can basically be configured as desired, for. B. as a on a mechanical, electromagnetic or optical stimulus out the

Switching state switching means 73. In the present example, it is designed as an inductive proximity switch 73, which is attenuated, for example, when the transport means 21 is on the support means 18, in particular in the work position to be detected.

The principle of the sensor or sensor device 63 recognizing the absence of a roll of material 08 on a transport means 21, in particular via a mechanical actuation, is at the top in preferred connection with a removal device 13, in particular with a stretch section 74 on a carrying device 18 included in the removal device 13 However, it is also on stretches 74 other stations, z. B. another loading, unloading or transfer station, in

Route network of a roller transport system. The above

Removal device 13 is seen from the perspective of the roller transport in this sense, at least one loading station 13, to which the roller carrier 07 to be removed roller 08 is received by the transport means 21 and so provided for transport on the downstream transport route. The term of the roller transport system should in principle comprise both only a simple, the route section 74 of the loading, unloading or transfer station comprehensive and only reaching to an adjacent transfer station transport route, as well as larger systems to a complex route network with branches and / or one or more further loading, unloading or transhipment stations provided in the route network and / or a warehouse.

In generalization the absence of a roll of material 08 on one

Transport means 21 detecting sensor or sensor device 63 may be provided for any section of a roller transport system, for which the unambiguous answer to the question of the loading state of the transport means 21, for example, from safety and / or control technology relevance. This can be used in addition to or instead of the application described at one of the transfer device 12 associated station of the route network in the area of another station in the route network of a roller transport system meaningful, where a loading or unloading of transport 21 with rolls of material 03; 08 takes place and / or is required.

The above explanations on the design of the sensor device 63 are thus to be generalized to sections of other stations to be transmitted with the proviso that the place of the comprehensive section 74

Carrying device 18 generalizes a the route section 74 comprehensive and the means of transport 21 serving as a type of road section bottom section 18 occurs, with the proviso that the track section 74 associated background takes the place of the support means 18 and the sensor 66 is thus arranged fixed in space with respect to the ground ,

The sensor device 63 can then in general on the output side with the further transport on the transport path controlling means, such as a drive control for the transport means 21 on the track section 74 and / or a subsequent transport section driving drive means, and / or - as in the above example - with a through the loading, unloading or transfer station to be performed process or process step controlling Control means 36 are in signal communication.

The top of the removal device 13 and the removal process and to carry out the recording means 19 used there; 21 mentioned is - where the corresponding application is not contrary - to transfer to an input side roller carrier 02 and the local removal of a residual role 03 '.
