Description

The invention relates to a method for optimizing the operation of web roll packages, in which the consumable required for packaging is provided in a set-up area in the apparatus. The invention further relates to a system for set-up for consumables of a device for packaging material web rolls.

Devices for the packaging of web rolls are known in a variety of embodiments of the prior art. These usually comprise at least one winding station, in which the web rolls are wrapped on its outer periphery with packaging material which projects beyond the end faces of the rollers a little and forms a so-called Faltüberstand, a folding station, by means of which the folding supernatant is flanged, one unit, the inner or outer end cover on the end faces of the material web rolls creates (Stirndeckelapplikationsstationen) and a pressing station, by means of which the outer end cover are pressed against the web rolls, these stations can be effective in individual process section areas.

The consumables required for packaging, in particular the packaging web rolls and end covers are arranged directly in the region of the wrapping station. The packaging material web rolls are arranged in a packaging material web dispensing device provided for this purpose and can be kept in stock in limited quantities also in the dispensing device. The end covers are used in so-called staging areas Area of the wrapping station and arranged in the area of action of so-called handling units, in particular devices for positioning and / or fixing of end caps. If the individual consumables are used up, they must be replaced. For this purpose, a monitoring of the individual, the set-up area forming staging areas, wherein the achievement of a predefined minimum amount either automatically detected by the operator or automatically generates a corresponding signal that indicates the requirement of a loading of the staging areas. In the worst case, this condition is recognized only after the system has come to a standstill, which is due to the used up packaging material. Otherwise, the device is stopped by the operator and retrofitted the required consumables. The resulting required continuous monitoring is very expensive and can result in mismatched retrofitting to a variety of required production interruptions, which significantly reduce the productivity of the device for packaging.

The invention is therefore based on the object, a method for optimizing the operation of devices for the packaging of web rolls, in which the consumables required for packaging is provided in a set-up area in the device to develop, minimizes downtime and the productivity of the packing system increase.

The solution according to the invention is characterized by the features of claims 1 and 12. Advantageous embodiments are described in the subclaims.

An inventive method for optimizing the operation of devices for the packaging of web rolls, in which the consumables required for packaging in a set-up area in the device is provided, is characterized in that at least a portion of the consumables required for packaging in the set-up area in Dependence of the web rolls to be packaged, in particular their parameters and number is prepared.

For the purposes of the invention, consumables are understood as meaning materials which are required for packaging during the packaging process, such as, for example, packaging material, end covers, glue and identification means, in particular labels or printing ink.

The solution according to the invention thus makes it possible to pre-equip consumables for a predefined number of material web rolls to be packaged and / or a predefined period of time, the entire consumable required for this number and / or duration being made available. Setup operations before the end of this period and / or before the end of the packaging of these web rolls eliminated. This means that production interruptions due to set-up processes can be excluded for this period. The monitoring effort is minimized and the operator can be used for other tasks. As a result, the number of required operating personnel can also be reduced overall. By optimally coordinating the processes at several packing stations, these can be operated by a smaller number of persons with the same capacity utilization of the individual packaging devices.

For an individual embodiment of the packaging according to customer requirements, the required consumable material is provided in an advantageous further development as a function of the properties of the packaging material required for packaging.

In order to achieve easily negotiable setup intervals, the pre-equipment is carried out depending on the material web rolls to be packaged in a predefined period of time. The period can be chosen arbitrarily, but this is preferably oriented to the shift times and the operating times of upstream facilities, such as slitter or machines for Production of material webs. The required consumable material is then prepared in a particularly advantageous manner as a function of the production output per unit time of a device upstream of the device, in particular machine for the production of fibrous webs or slitter. This allows a timely packaging of the production output and reduces the risk of production stagnation.

• Maschinengeschwindigkeit der vorgeordneten Produktionsanlage
• Taktzeit der Vorrichtung zur Verpackung von Materialbahnrollen
• Anzahl der Materialbahnrollen
• Parameter der Materialbahnrollen, insbesondere Dimensionierung.

The required consumable material is preferably pre-equipped depending on at least one of the following quantities:

• Machine speed of the upstream production plant
• Cycle time of the device for packaging material web rolls
• Number of material web rolls
• Parameters of the material web rolls, in particular dimensioning.

The setup process, in particular the loading of the staging areas themselves can be done manually or at least partially automated. The latter possibility offers the advantage that under certain circumstances, an interruption of production can be avoided, since the setting is possible even when still working device.

To ensure the set-up intervals, the set-up takes place taking into account a safety factor, i. an addition to consumables. Thereby, e.g. Lid losses are compensated during packaging in the consumable to be considered.

In a further development, the setup specification preferably takes place taking into account the consumable material remaining in the setup area. This can optimize the use of consumables.

In terms of the device, a system for setting up consumables of a device for packaging web rolls is constructed in such a way and designed such that this at least one device for detecting / specifying the web rolls to be packaged or the material web rolls to be packaged per period, a device for detecting / specifying the parameters of the web rolls, means for detecting / presetting of, the packaging material used VM at least indirectly characterizing sizes and optionally a device for specifying a time duration T _soll and an evaluation and / or analysis device. The functions of individual devices can also be combined or executed by a common device.

On the basis of the processed in the evaluation and analysis data manipulated variables are created, which serve to control an information and maintenance system and / or the control of the adjusting devices for setting the set-up area.

The coupling of all components of the set-up system may be via fixed line connections or preferably wirelessly, i. via radio or infrared.

In order to take into account the production output of upstream installations, the device for detecting / specifying the material web rolls to be packaged or the material web rolls to be packaged is preferably directly from a device for detecting / specifying the production output of a production plant upstream of the packaging device, in particular a control device / controller, within a predefined period of time one of the device upstream plant formed. This also allows for rapid adjustments as production changes.

To be able to remove unneeded consumables from the setup area. Is at least one device for detecting the remaining consumables is provided in the setup area, which is coupled to the evaluation and / or analysis device. According to the required setup requirements The remaining consumables can be included in the new setup specification or removed.

The FIG. 1b illustrates in a schematic simplified representation and based on a signal flow diagram, the basic principle of a method according to the invention for optimizing the operation of a in FIG. 1a Such devices 1 can be made very different in complexity depending on the type of packaging, the chosen method for wrapping with packaging material and the packaging materials used. The FIG. 1a illustrates exemplified schematically in a highly simplified representation of the structure of a device 1 for the packaging of web rolls 2.1 to 2.n in a view from above, which is suitable for use of the method according to the invention. This comprises at least one wrapping station 3, in which the material web rolls 2.1 to 2.n to be packaged are wrapped with packaging material. Furthermore, at least one device, here two devices 4.1, 4.2 for positioning and fixing of End covers S provided on the end faces of a single web roll 2.n. Depending on the type of positioning and fixation, this device may be arranged upstream of the wrapping station 3 or arranged in the effective region thereof. In the former case takes place, but not shown here, a plant of the end cover S to the individual end faces of a web roll 2.n, the end cover S are transported in the investment position together with the respective web roll 2.n in the wrapping station 3. In the second case, corresponding handling devices, preferably in the form of industrial robots are provided, which are also referred to as a manipulator device and the recording and conditioning of the front cover S at the end faces of the individual web rolls 2.1 to 2.n serve. These further fix the position of the end cover S during the wrapping process and are therefore arranged in the region of the wrapping station 3 or be effective on this. In general, in each case a front cover unit, consisting of an inner end cover S _I and an outer end cover S _A at each one end face of the material web roll to be wrapped 2.1 to 2.n used to fix the packaging. Here, the inner end cover S _I is first positioned and fixed by the folded fold edges of the packaging material in its position on the front side of the web roll 2.n. After the folding process, the outer end cover S _{A is} positioned and fixed with the fold edges and the inner end cover S _I. In order to achieve a very high number of cycles, the front cover S in the form of end cover stacks 5.1, 5.2 arranged in the handling relation manner effective range of the devices 4.1 and 4.2. This applies both for inner end cover S _I and outer end cover S _A. Also for the wrapping station 3 are a variety of execution options. In this case, the wrapping station 3 comprises at least one packaging material dispensing device 6, which is fixedly arranged depending on the type of packaging to be realized during the packaging process, wherein the individual web roll 2.n according to a first embodiment also stationary, according to a second embodiment is movable relative to this. In a further embodiment, it is also conceivable, the packaging material dispensing device 6 and the Packaging web rolls carrying part also to move, the movement in stationary web roll 2.n or relative to this is done with moving web roll 2.n. As a result, different packaging patterns can be realized. The packaging may be formed overlapping or abutting, wherein packaging material in the form of the packaging material webs in the circumferential direction at an angle to the longitudinal axis of the web roll 2.n is wound around the outer circumference of the web roll 2.n or perpendicular to the longitudinal axis. The longitudinal axis of the material web roll 2 is formed by its axis of symmetry. The packaging material is disposed in the packaging material dispenser 6. Preferably, this comprises a storage area in which packaging material web rolls can be kept in stock. As a further unit preferably a device 4.2 for positioning and / or positional fixation for the outer end cover S _A , for example in the form of a packing press 7 can be used. Additional and optionally used units are marking devices 9, in particular labeling devices 8 for identifying the packaging or for affixing markings thereon. To ensure optimum packaging, in addition to the packaging material V and the end caps S _I , S _A and the means required for labeling, such as labels E also other consumables in the form of glue L are necessary. In the known embodiments according to the prior art while the device 1 is supplied with the consumables VM by these in a so-called set-up area 10, which is composed of the individual Bereitstellungsbreichen 11.1 to 11.n, spatially separated from each other or directly each other may be located adjacent to be held. From this set-up area 10, the required consumables VM are then removed in a timely manner, at least for the packaging material V and the end covers S, and used to operate the device 1 in this manner. However, it is necessary to monitor the consumption of the consumables VM in order to be able to retrofit them if necessary. As this resources, especially in the form of working hours as well as production time binds, because the device 1 is deactivated for each set-up process, it is according to the invention provided which supplies VM to the packaging of each roll of web material 2.n in the setup area 10 and the various staging areas 11.1 to 11.n _{is intended} as a function of either a predefined amount of N2 to be packaging material web rolls 2.1 to 2.n and / or in a predefined period of time T _soll required to be wrapped web rolls 2.1 to 2.n ready to deliver. The material web rolls 2.1 to 2.n to be packaged per predefined period of time T _soll are understood here as a function of the production output PA of an upstream installation 12, in particular a slitter-winder 14 or machine for producing fibrous webs, according to a particularly advantageous embodiment.

The FIG. 1b illustrates an embodiment of a method according to the invention with set-up specification as a function of the production output PA on the basis of a signal flow diagram. Accordingly, a number N2 of material web rolls per time period T ₁₂ , which are to be packaged, are output by a production facility 12 upstream of the device 1, for example in the form of a slitter-winder 14. For the determination of the required consumable VM, it _is also necessary to know the parameters describing the material web rolls 2.1 to 2.n to be wrapped, in particular dimensional sizes. These are here designated PD2.1 to PD2.n and include property and / or dimensions such as diameter, width. This data may be provided by the upstream production facility 12 or one of its associated controls. Another criterion for the determination of the consumable VM _{to be provided} is the type and properties of the sizes to be selected the descriptive packaging PE, which can be specified individually according to the customer. This applies in addition to the wrapping type and the packaging materials used for this purpose V with appropriate packaging material web widths and front lid sizes and the possibilities of labeling. These are also used for evaluation and analysis regarding the required to be provided consumable VM _should , which is composed of the sum of the packaging material, in particular the packaging webs V, the front cover S _I , S _A and other required consumables such as labels E and / or adhesive, in particular glue L included. The packaging material V as well as the end covers S _I , S _A are a function of the production output PA, in particular per predefined time unit of a production facility 12 upstream of the apparatus 1, the parameters describing the material web rolls 2.1 to 2.n to be wrapped, in particular dimension sizes PD2.1 to PD2.n and the sizes PE describing the type and characteristics of the packaging to be selected. The marking, in particular labels E are determined by the sizes PE and optionally by further, at least indirectly descriptive variables. The required consumable VM _is to _be equal to the sum of the packaging webs V, the end cover S _I , S _A and other required consumables such as labels E and / or adhesives such as glue L. This is then provided for the predefined period T _soll , according to FIG. 1b By way of example according to a particularly advantageous embodiment, the predefined period of time T _soll corresponds _to a layer length, so that in particular in non-continuous operation at the end and at the beginning of a layer such a setup process can be carried out and the consumables VM then certainly sufficient for the next layer, without that a retrofit must be made.

In a particularly advantageous embodiment, the solution according to the invention is always used in connection with machines for producing fibrous webs or the winding devices of slitter-cutting machines 14 downstream devices 1 are used. In this case, preferably the device 1 for packaging quasi online downstream of the slitter 14, as in a schematic simplified representation in FIG. 1a reproduced, from which the web rolls 2.1 to 2.n are transported to the device 1 by means of a transport device. However, it is also conceivable to package the Material web rolls 2.1 to 2.n can be seen from a roll magazine, then with respect to the operating parameters an optimal operation of the device 1 is selected and depending on this, the number of web rolls to be packaged N2 per desired period of time T _{soll is} determined.

According to a particularly advantageous embodiment in the FIG. 2a can be incorporated into the process nor a correction component by the specifications for the individual consumables VM are increased in response to interference factors in a corresponding manner by a security allowance. This is as a correction factor K in the calculation of the necessary consumable VM _{is to} considered for integration into the setup area 10. In a further advantageous development according to FIG. 2b it is provided, in particular in embodiments with continuous shift operation in which the number of necessary interruptions in production to be reduced to a minimum as far as possible, the T _{Ü is,} after a predefined period of time at least in stock in the setup area 10 supplies VM which is the from the respective in individual supply ranges 11.1 to 11.n existing consumables VM compound to capture. The detection can be carried out continuously or as already stated in predefined time intervals. The time period T _u is set to be shorter than the predefined time period T _set. In the process, the renewed production output _{N2new is} determined in advance for the next predefined period of time T _sollew and the consumables VM required for this purpose are _newly calculated. Taking into account the still present in the setup area 10 and unneeded supplies VM _is a re-feeding performed. The region _Tnewnew can _connect to the original region T _soll but also already to the monitoring period T _Ü . In this case, already during operation, a determination of the required consumable VM _sollnew for the new layer. The FIG. 3 On the other hand, a recalculation after expiration of the predefined time period T _soll illustrates.

Depending on the arrangement of the preparation areas 10 and the realization of the change of the empty packaging material carrier, both automatic re-equipment and manual retrofitting can take place. If the inventive method according to FIG. 4a used for manual retrofitting, the packaging material VM is retrofitted so that this whenever possible for all individual consumables VM in the form of packaging material V, end caps S, labels E and glue L for a predefined period T _soll and in this possible enclosure of the Quantity N2 to material web rolls 2.1 to 2.n sufficient and all consumables VM, each at the same time, that is to be retrofitted at the same time. The machine or device 1 then stands still only once and can work during the entire mode of operation in the predefined time period T _soll without disturbances. The in the FIGS. 1 and 2 illustrated embodiment with a preferably selected period of time T _is in the form of a layer length offers, as already stated, the advantage that within the layer no interruptions due to retrofitting in the device 1 for the packaging of web rolls 2 are to be expected and thus the device 1 continuously over the entire shift can work. However, the time duration T _soll can also be selected shorter or longer. This also depends in detail on the possibility of the advance planning of the output of production PA or of the material web rolls 2.1 to 2.n available for packaging.

The FIGS. 4a to 4c illustrate in a schematic simplified representation of the structure of a system according to the invention 15 for setup and the implementation of setup specifications. For this purpose, the system 15 comprises at least one device 16 for detecting / specifying the production output PA of a production plant 12 upstream of the device 1, which can be fed continuously directly to the device 1 or is taken from a buffer in the form of a magazine. The device 16 can be formed by a control and / or regulating device of the upstream production plant or a separate facility. Furthermore, the set-up system 15 includes at least one device 17 for acquiring / specifying the parameters PD of the web rolls 2.1 to 2.n ejected from the production line per unit time and a device 18 for detecting / specifying the used packaging material VM at least indirectly characterizing quantities PE and, depending on the realization of the method for setting up, a device 19 for specifying a time duration T _soll , which corresponds to an operating period for which the materials prepared by means of the setting process are considered sufficient. In this case, the device 16 preferably detects the material web rolls to be packaged for a predefined period of time T _soll in order to be able to provide the required consumable material for this period as well. The device 16 may be designed such that it only detects the number of required material web rolls 2.1 to 2.n to be packaged. However, it is also conceivable that this also simultaneously assumes the function of determining the parameters of the material web rolls 2.1 to 2.n and thus the function of the device 17. This means, in particular, the parameters of the material web rolls 2.1 to 2.n determining the amount of packaging material, in particular diameter and width. For standard use unit packaging, the device 18 may be optional. The data given via the devices 16 to 19 are supplied to an analysis and / or evaluation device 20 and in this the necessary set-up specifications are created from the resulting dependencies and functional relationships. Be generated manipulated variables Y depending on the particular required consumable VM _to which are merely generating corresponding information and / or maintenance signals that prompt the operator to implement the Rüstvorgabe, which can be done, for example, via a display device 21st However, it is also possible to generate actuating signals for the actuation of adjusting devices for the automated feeding of the setting area 10. These individual devices 16 to 19 can be coupled with the evaluation and / or analysis device 20. In this processing takes place via the means 16 to 19 predetermined or detected input variables, which are used to determine the required consumables VM _should serve. From this characteristic, a signal can then be generated, which is present as an information signal in the form of, for example, an optical signal or as a control signal.

The possibilities of the setup specifications for the individual setup processes are based on schematized representations of the system 15 in the FIGS. 4a to 4c played. Retrofitting can be done manually, semi-automatically or fully automated. This depends essentially on the design of the individual device 1 and the configuration of the set-up area 10 FIG. 4a In doing so, operating personnel become active, whereby the individual consumables VM are _to spend in the respective provision areas 11.1 - 11.n. In FIG. 4b is shown in a simplified schematic representation of a combination of automated provisioning and operating personnel, while Figure 4c a fully automated deployment. In this case, however, the individual staging areas 11.1 to 11.n are arranged such that these corresponding feed devices for the respective consumable material can be assigned and these are also freely accessible. In this case, however, it is preferably carried out a pre-equipment outside the set-up area 10, wherein the Vorrüstbereiche contained the pre-equipped material is then connected via the feeders with the staging areas 11.1 to 11.n of the setup area 10 for direct and quick loading.

According to a further development, not shown here, however, the variables which _are taken into account with a further device for detecting the existing consumable VM are processed in the evaluation or analysis device 20, whereby the consumables present in the provision regions in the set-up region 10 of the device 1 are available and be taken into account in the required quantity. It goes without saying that in all processes for the consumable, the individual determination processes for each packaging material web rolls, end covers and additional materials such as adhesives, labels separately for themselves be determined, and always on the basis of the required web rolls to be wrapped.

The solution according to the invention is not limited to the illustrated embodiments. It is crucial that, depending on a desired throughput by the device 1 for the packaging of web rolls 2 per predefined time unit T _soll, a set-up is made, which avoids a standstill of the device 1 in this period. In a particularly advantageous embodiment, the individual set-up specifications are implemented in such a way that the charge in the individual staging areas 11.1 to 11.n are further arranged with respect to the temporal sequence of the removal of packaging material from them in particular with changing material web roll to be wrapped within a predefined period of time that these are also accessible one after the other. Thus, for example, different end cover sizes, which are _to be processed within the predefined time period T _soll , are arranged in the order of their execution in the set-up area 10.
