Description

[0001] This patent application claims the priority of German patent application DE 10 2022 207 584.6, the content of which is incorporated herein by reference. Technical Field

[0002] The invention relates to an arrangement, in particular as part of a corrugated board system, and capable of producing a single-face laminated corrugated board web. The invention also relates to a corresponding method. Background Art

[0003] As is known, in an arrangement with an apparatus for producing a single-sided laminated corrugated board web and a material web unwinding device arranged upstream thereof, the position of the material webs is detected before they are glued together. However, before the glued connection, the material webs can still shrink or move in their transverse direction relative to each other. This can result in corrugated board of not particularly high quality. Furthermore, glue can stick to the slotting rollers due to incorrect positioning of the glue dam of the gluing device. The apparatus for producing a single-sided laminated corrugated board web or the entire corrugated board system then has to be stopped to clean the slotting rollers. Summary of the invention

[0004] The object of the invention is to overcome the disadvantages of the prior art. In particular, the object of the invention is to provide an arrangement which allows a particularly efficient and sustainable production of corrugated board. Furthermore, corrugated board of extremely high quality can be produced. Furthermore, a corresponding process should be provided.

[0005] According to the invention, this object is achieved by the features specified in independent claims 1 and 15. The core of the invention consists in at least one non-contact temperature measuring device, which is assigned to a single-sided laminated corrugated cardboard web and is capable of measuring or detecting the temperature of at least one area, such as one side or both sides, preferably at least the edge side, of the single-sided laminated corrugated cardboard web in a non-contact or contactless manner. It is advantageous if the at least one non-contact temperature measuring device is capable of measuring the temperature in at least one planar or linear area of ​​the single-sided laminated corrugated cardboard web. (Direct) contact between the temperature measuring device and the single-sided laminated corrugated cardboard web is not necessary for the temperature measurement. During the temperature measurement, the temperature measuring device and the single-sided laminated corrugated cardboard web are preferably spaced apart from each other.

[0006] It is advantageous if at least one non-contact temperature measuring device measures at least one surface temperature of the single-faced laminated corrugated cardboard web at least in a region. The non-contact temperature measurement is preferably based on an evaluation of radiation, in particular infrared radiation, or energy, in particular infrared energy, radiated from the single-faced laminated corrugated cardboard web, or a measurement thereof. The detected radiation or energy is converted into a temperature signal, in particular an electrical temperature signal. Preferably, a temperature distribution or a temperature difference of the single-faced laminated corrugated cardboard web is measurable or identifiable.

[0007] The at least one non-contact temperature measuring device is preferably capable of measuring the actual temperature of the adjacent single-face laminated corrugated board web, preferably continuously. It is preferably capable of measuring the temperature actively and / or passively. In active temperature measurement, for example, radiation from at least one radiation source, such as an infrared light source, is used.

[0008] For example, at least one non-contact temperature measuring device comprises in each case a non-contact temperature measuring device, which can be arranged, for example, stationary or can be displaced in the transverse direction or width direction of the single-faced laminated corrugated board web, ie perpendicularly to its conveying direction or longitudinal direction.

[0009] Optionally, the at least one non-contact temperature measuring device has, for example, in each case at least two, preferably exactly two, non-contact temperature measuring devices which are arranged fixedly or are displaceable in the transverse direction or width direction of the single-face laminated corrugated board web.

[0012] The at least one non-contact temperature measuring device and the processing unit are combined into one unit, for example. Alternatively, they are constructed or arranged separately from each other.

[0013] The bonding or gluing connection of the first and second material webs to one another takes place, for example, exactly in the center or at the edge. Preferably, there is a center or edge alignment or adjustment of the material webs.

[0017] The gluing device preferably has a glue container and a glue roller. It is advantageous if the glue roller forms a gluing gap with the first slotting roller for guiding and gluing the first material web or the corrugated web. Advantageously, the glue roller applies the glue located in the glue container to the fluting tips of the corrugated web. The gluing device is advantageously arranged downstream of the slotting device in the conveying direction of the corrugated web.

[0018] The pressing device is preferably a pressing belt device, which advantageously has at least two pressing belt deflection rollers and an endless pressing belt guided around the pressing belt deflection rollers. The pressing belt preferably presses on the second material web, which in turn presses on the endless corrugated web provided with glue and resting on the first notching roller. The pressing device is preferably arranged downstream of the notching device in the conveying direction of the corrugated web.

[0019] The arrangement is preferably part of a corrugated board system.A double-faced laminated corrugated board web may preferably be produced from a single-faced laminated corrugated board web.

[0020] Further advantageous embodiments of the invention are disclosed in the dependent claims.

[0021] It is advantageous if the thermographic device according to dependent claim 2 is equipped with an optical system. Thermography, in particular infrared thermography, is advantageously used to measure the temperature of a single-sided laminated corrugated cardboard web. The contactless temperature measurement is preferably based on an optical evaluation of radiation, in particular infrared radiation, or energy, in particular infrared energy, radiated from the single-sided laminated corrugated cardboard web, or its measurement. Based on the detection of the radiation or energy of the single-sided laminated corrugated cardboard web, an electronic image representing the temperature distribution of the single-sided laminated corrugated cardboard web is advantageously generated. The thermal radiation of the single-sided laminated corrugated cardboard web is recognizable or visualized. It is advantageous if the thermographic device comprises at least one photoreceiver or microbolometer or array. The arrangement preferably has a corresponding display, such as a screen, for displaying the temperature of the single-sided laminated corrugated cardboard web.

[0022] The arrangement according to dependent claim 3 is particularly effective. For this purpose, the at least one non-contact temperature measuring device is preferably capable of detecting or measuring at least one longitudinal edge region, in particular its temperature distribution. Its temperature distribution can advantageously be identifiable, visualized or ascertainable by the at least one non-contact temperature measuring device or the processing unit. Preferably, the temperature distribution of at least two longitudinal edge regions of the single-faced laminated corrugated cardboard web is identifiable, visualized or ascertainable. The temperature distribution of a central region of the single-faced laminated corrugated cardboard web can be detected or measured. Alternatively, no temperature measurement is performed.

[0023] The design according to dependent claim 4 allows, for example, conclusions to be drawn about the positioning of the corrugated web relative to the web of second material. During the temperature measurement of the single-sided laminated corrugated cardboard web, at least one longitudinal edge or side edge of the corrugated cardboard web, in particular its position or orientation, can preferably be detected or measured by at least one non-contact temperature measuring device. Advantageously, both longitudinal edges of the corrugated web can be detected or measured by at least one non-contact temperature measuring device. Preferably, at least one non-contact temperature measuring device or processing unit is capable of identifying, determining or visualizing at least one longitudinal edge of the corrugated web. At least one longitudinal edge of the corrugated web has a different temperature than at least one adjacent area of ​​the single-sided laminated corrugated cardboard web.

[0024] The arrangement according to dependent claim 5 is particularly economical. During the temperature measurement of the single-sided laminated corrugated cardboard web, at least one side glue edge, in particular its position or course, can preferably be detected or measured by at least one contactless temperature measuring device. Advantageously, both side glue edges can be detected or measured by at least one contactless temperature measuring device. It is advantageous if at least one contactless temperature measuring device or the processing unit is able to identify, determine or visualize at least one side glue edge. At least one side glue edge has a different temperature than at least one adjacent area of ​​the single-sided laminated corrugated cardboard web.

[0025] The arrangement according to dependent claim 6 produces a single-sided laminated corrugated cardboard web or corrugated cardboard, which has a particularly high quality. The arrangement or the course of the at least one circumferential groove can preferably be determined by measuring the temperature of the single-sided laminated corrugated cardboard web. Preferably, the arrangement or the course of several (advantageously all) circumferential grooves can be determined. It is advantageous if the at least one circumferential groove can be identified, determined or visualized by at least one non-contact temperature measuring device or processing unit. In the vicinity of the area where the single-sided laminated corrugated cardboard web passes through the at least one circumferential groove, the single-sided laminated corrugated cardboard web has a different temperature than at least one adjacent area of ​​the single-sided laminated corrugated cardboard web.

[0026] The at least one circumferential groove is preferably a suction groove. It is preferably configured as an infinite groove. It is advantageous if the processing unit knows or can calculate the course or position of the at least one circumferential groove, in particular its position relative to the longitudinal extent of the grooved roller used. For example, for this purpose the processing unit has recourse to a database or external data, for example about the grooved roller. The spaced arrangement from the longitudinal edge of the first material web to the at least one circumferential groove, in particular in the transverse or longitudinal direction of the grooved roller, results in a particularly high-quality single-face laminated corrugated board web.

[0027] A particularly high quality single-face laminated corrugated board web is also provided by the design according to the dependent claim 7. In particular, the processing unit can check whether the correct position or set distance of the corrugated web to the at least one circumferential groove is maintained.

[0028] By means of the design solutions of dependent claims 8 and 9, edge trimming or waste of the single-sided laminated corrugated cardboard web can be reduced or avoided. This is particularly effective and sustainable. The processing unit or at least one contactless temperature measuring device is preferably capable of determining at least one single-layer edge region when measuring the temperature of the single-sided laminated corrugated cardboard web. Only the corrugated web or the web of the second material is located in the single-layer edge region. Outside the single-layer edge region, the single-sided laminated corrugated cardboard web is two-layered.

[0029] The embodiments according to the dependent claims 10 and 11 also lead to a particularly efficient and sustainable production of single-face laminated corrugated board webs. The transverse position of the material webs can be varied relative to one another, in particular in an apparatus for producing single-face laminated corrugated board webs.

[0030] For example, if necessary, according to dependent claim 10, the first unrolling device is able to influence the first material web, for example to slide or deflect it in its transverse direction so that it is shifted accordingly. The corresponding shifting, for example sliding or tilting, leads to a change in the orientation of the first material web in its transverse direction. It is advantageous if, at least in the device for producing a single-sided laminated corrugated board web and / or relative to the second material web, a corresponding change in the transverse position of the first material web occurs, in order, for example, to minimize at least one single-layer edge region. For this purpose, preferably, at least one device of the first unrolling device can be shifted accordingly. In particular, at least one receiving device of the first unrolling device can slide and / or tilt or tip over laterally from its basic position or neutral position. In the basic position, the first material web is normally unrolled.

[0031] For example, according to dependent claim 11, the second unfolding device is able to influence the second material web in such a way that, for example, it slides or deflects in its transverse direction so that it is shifted accordingly. The corresponding shifting, for example sliding or tilting, leads to a change in the orientation of the second material web in its transverse direction. It is advantageous if the transverse position of the second material web is changed accordingly at least in the device for producing a single-sided laminated corrugated board web and / or relative to the first material web, in order to, for example, minimize at least one single-layer edge area. For this purpose, preferably, at least one device of the second unfolding device can be shifted accordingly. In particular, at least one receiving device of the second unfolding device can slide and / or tilt or tip over laterally from its basic position or neutral position. In the basic position, the second material web is unfolded normally.

[0032] The design according to dependent claim 12 also allows a particularly economical and sustainable production of single-sided laminated corrugated board webs or corrugated board. It is advantageous if the gluing device has at least one glue dam which is displaceable in the transverse direction of the corrugated web and which is able to spatially limit the application of glue to the corrugated web, in particular transversely outwards, or to limit the width of the gluing. The at least one glue dam is preferably adaptable to the width or the direction of the corrugated web. Preferably, the gluing device has two glue dams. Each glue dam is preferably plate-shaped.

[0033] The at least one first transverse position detection device according to dependent claim 13 preferably operates in a contactless manner and advantageously operates continuously. It is advantageous if it is designed as a light barrier, a sensor, a camera, an ultrasonic detection device, an infrared detection device or the like. It is preferably capable of detecting the current position or orientation of the first material web in its transverse direction. As a result, a single-face laminated corrugated board web can be produced extremely efficiently, also of a particularly high quality.

[0034] The at least one second transverse position detection device according to dependent claim 14 preferably operates in a contactless manner and advantageously continuously. It is advantageous if it is designed as a light barrier, a sensor, a camera, an ultrasonic detection device, an infrared detection device or the like. It is preferably capable of detecting the current position or orientation of the second material web in its transverse direction. As a result, a single-face laminated corrugated board web can be produced extremely efficiently, also of a particularly high quality.

[0035] The dependent claims also relate to preferred embodiments of the method according to independent claim 15 .

[0036] The terms "upstream", "downstream", "upstream", "downstream" and the like as used herein particularly refer to the transport direction of the associated or assigned web material.

[0037] The signal connection shown can be wired or wireless. Corresponding signals or information can be transmitted in this manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] First reference Figure 1 , a corrugated web device (not shown as a whole) comprises a device 1 for producing an infinite single-faced laminated corrugated board web, which is capable of producing an infinite single-faced laminated corrugated board web 2.

[0046] A first splicing device 3 and a second splicing device 4 are arranged upstream of the device 1 for producing a single-face laminated corrugated board web.

[0047] The first splicing device 3 is designed as an intermediate web splicing device and comprises a first unrolling device 7 for unrolling a limited first intermediate web 5 from a first intermediate web roll 6 and a second unrolling device 9 for unrolling a limited second intermediate web from a second intermediate web roll 8 .

[0048] The first splicing device 3 also has a base frame 10, which has at least one base frame base 11, at least one base frame column 12 and at least one base frame bracket 13. The at least one base frame base 11 is fixed to the floor or the foundation. At least one base frame column 12 extending vertically or perpendicular to the floor is arranged on the at least one base frame base 11. At least one base frame bracket 13 is arranged at the end of the at least one base frame column 12 opposite to the at least one base frame base 11 and extends parallel to the floor.

[0049] At least one base support 13 carries a splicing device of the first splicing device 3. The first finite intermediate web 5 and the second finite intermediate web are connected to each other by the splicing device to provide an infinite intermediate web 20. The first finite intermediate web 5 and the second finite intermediate web are guided into the splicing device by respective intermediate web rollers 6, 8, respectively. The splicing device is preferably designed as a connecting and cutting device. The intermediate webs 5, 20 form a first material web. It has two intermediate web longitudinal edges or side edges 63 ( Figure 3 ).

[0050] The base frame 10 carries an elongated first carrier device extending horizontally and carrying the first unrolling device 7. The first unrolling device 7 has two first carrier arms 14, which are arranged along the first carrier device and each of which carries a first receiving portion 15. The first receiving portion 15 is guided into the central opening of the first intermediate web roll 6. It engages into the first intermediate web roll 6 from both end faces and forms a first receiving device. The longitudinal center axis of the first intermediate web roll 6 then extends parallel to the first carrier device.

[0051] The first carrier arms 14 can slide uniformly together along the first carrier means, which causes the first intermediate web roll 6 to slide along its longitudinal center axis or the finite first intermediate web 5 or infinite intermediate web 20 unfolding therefrom in its transverse or width direction. Alternatively or additionally, they can pivot relative to each other about the first carrier means, which enables the first intermediate web roll 6 to tilt and thus enables the finite first intermediate web 5 or infinite intermediate web 20 to deflect in its transverse direction.

[0052] The base frame 10 also carries an elongated second carrying means extending horizontally and parallel to the first carrying means. The second carrying means carries a second deployment means 9. The first and second deployment means 7, 9 are arranged opposite each other relative to at least one base frame column 12 or base frame base 11.

[0053] The second unwinding device 9 has two second carrying arms 16, which are arranged along the second carrying means and each carrying arm 16 carries a second receiving portion 17. The second receiving portion 17 is guided into the central opening of the second intermediate web roll 8. It engages into the second intermediate web roll 8 from both end faces and forms a second receiving means. The longitudinal center axis of the second intermediate web roll 8 then extends parallel to the second carrying means.

[0054] The second carrier arms 16 can slide uniformly together along the second carrier means, thereby causing the second intermediate web roll 8 to slide along its longitudinal center axis or in the transverse or width direction of the finite second intermediate web or the infinite intermediate web 20. Alternatively or additionally, they can be pivoted relative to each other about the second carrier means, which causes the second intermediate web roll 8 to tilt, thereby making it possible to deflect the finite second intermediate web or the infinite intermediate web 20 in its transverse direction.

[0055] For a corresponding transfer of the first supporting arm 14 , the first joining device 3 has at least one corresponding first transfer unit 18 , which comprises, for example, at least one electric, pneumatic or hydraulic drive.

[0056] For a corresponding transfer of the second carrying arm 16 , the first joining device 3 has at least one corresponding second transfer unit 19 which comprises, for example, at least one electric, pneumatic or hydraulic drive.

[0057] The second splicing device 4 is constructed in the same manner as the first splicing device 3. It is designed as a cover web splicing device and comprises a third unrolling device 23 for unrolling a limited first cover web 21 from a first cover web roll 22 and a fourth unrolling device 25 for unrolling a limited second cover web from a second cover web 24.

[0058] The second splicing device 4 also has a base frame 27, which has at least one base frame base 28, at least one base frame column 29 and at least one base frame bracket 30. The at least one base frame base 28 is fixed to the floor or the foundation. At least one base frame column 29 extending vertically or perpendicular to the floor is arranged on the at least one base frame base 28. At least one base frame bracket 30 is arranged at the end of the at least one base frame column 29 opposite to the at least one base frame base 28 and extends parallel to the floor.

[0059] At least one base support 30 carries a splicing device of the second splicing device 4. By means of the splicing device, the limited first cover web 21 and the limited second cover web are connected to each other to provide an unlimited cover web 26. The limited first cover web 21 and the limited second cover web are guided into the splicing device by respective cover web rollers 22 and 24, respectively. The splicing device is preferably designed as a connecting and cutting device. The cover webs 21, 26 form a second material web. It has two cover longitudinal edges or side edges 64 ( Figure 3 ).

[0060] The base frame 27 carries an elongated third carrier device, which extends horizontally and carries the third unrolling device 23. The third unrolling device 23 has two first carrier arms 31, which are arranged along the third carrier device and each of which carries a first receiving portion 32. The first receiving portion 32 is guided into the central opening of the first cover web roll 22. It engages into the first cover web roll 22 from both end faces and forms a first receiving device. The longitudinal center axis of the first cover web roll 22 then extends parallel to the third carrier device.

[0061] The first carrier arms 31 may slide uniformly together along the third carrier means, which causes the first cover web roll 22 to slide along its longitudinal center axis, or causes the limited first cover web 21 or the infinite cover web 26 unrolled therefrom to slide in its transverse or width direction, respectively. Alternatively or additionally, they may pivot relative to each other about the third carrier means, which allows the first cover web roll 22 to tilt, thereby allowing the limited first cover web 21 or the infinite cover web 26 to deflect in its transverse direction.

[0062] The base frame 27 also carries an elongated fourth carrying device extending horizontally and parallel to the third carrying device. The fourth carrying device carries a fourth deployment device 25. The third deployment device 23 and the fourth deployment device 25 are arranged opposite each other relative to at least one base frame column 29 or base frame base 28.

[0063] The fourth unwinding device 25 has two second carrying arms 33, which are arranged along the fourth carrying means and each carrying arm 33 carries a second receiving portion 34. The second receiving portion 34 is guided into the central opening of the second cover web roll 24. It engages into the second cover web roll 24 from both end faces and forms a second receiving device. The longitudinal center axis of the second cover web roll 24 extends parallel to the fourth carrying means.

[0064] The second carrying arms 33 can slide uniformly together along the fourth carrying means, which causes the second cover web roll 24 to slide along its longitudinal center axis and the limited second cover web or infinite cover web 26 unrolled therefrom to slide in its transverse or width direction. Alternatively or additionally, the second carrying arms 33 can pivot relative to each other around the fourth carrying means, which causes the second cover web roll 24 to tilt, thereby making it possible to deflect the limited second cover web or infinite cover web 26.

[0065] For a corresponding transfer of the first supporting arm 31 , the second joining device 4 has at least one corresponding third transfer unit 35 , which comprises, for example, at least one electric drive, pneumatic drive or hydraulic drive.

[0066] For a corresponding transfer of the second carrying arm 33 , the second joining device 4 has at least one corresponding fourth transfer unit 36 ​​, which comprises, for example, at least one electric drive, pneumatic drive or hydraulic drive.

[0067] The endless intermediate web 20 is fed to the device 1 for producing a single-faced laminated corrugated board web in a first transport direction 38 via deflection rollers 37 , while the endless cover web 26 is fed to the device 1 for producing a single-faced laminated corrugated board web in a second transport direction 40 via a heating device 39 .

[0068] The device 1 for producing a single-sided laminated corrugated board web comprises a slotting device 41 with a first slotting roller 42 and a second slotting roller 43 for producing an infinite corrugated web with fluting from an infinite intermediate web 20. The slotting rollers 42, 43 are arranged adjacent to each other. They form a slotting gap for guiding and slotting the infinite intermediate web 20. The slotting rollers 42, 43 are supported to be rotatable or rotatably driven. The axes of rotation of the slotting rollers 42, 43 extend parallel to each other and preferably one above the other.

[0069] like Figure 3 As shown, the first slotted roll 42 has a plurality of circumferential grooves 44 that are spaced apart along the first slotted roll 42 and extend around the longitudinal center axis of the first slotted roll 42. They are open outwardly and infinite. The circumferential grooves 44 extend in a plane extending perpendicular to the longitudinal center axis of the first slotted roll 42 and are in flow communication with at least one vacuum source so that the infinite intermediate web 20 is held on the first slotted roll 42 and cleanly rests in its slotted grooves.

[0070] In order to connect the endless cover board web 26 to the endless corrugated intermediate web or the corrugated web 20 to form the single-face laminated corrugated board web 2, the device 1 for producing the single-face laminated corrugated board web has a gluing device 45, which advantageously includes a glue roller 46, a glue drop roller 47 and a glue container 48. In order to guide and glue the endless corrugated intermediate web or the corrugated web 20, the glue roller 46 forms a gluing gap with the first slotting roller 42. The glue in the glue container 48 is applied to the corrugated tip of the endless corrugated web 20 by the glue roller 46. The glue drop roller 47 is assigned with the glue roller 46 for forming a uniform glue layer on the glue roller 46.

[0071] In addition, the glue coating device 45 has two glue dams 49 ( Figure 3 ), in use, the two glue dams 49 are closely against the glue-spreading roller 46 and the glue-dropping roller 47. For this reason, each glue dam 49 preferably has a corresponding sealing edge. The glue dam 49 extends perpendicularly to the glue-spreading roller 46 and the glue-dropping roller 47.

[0072] The glue dams 49 are arranged at intervals along the glue coating roller 46 and the glue dripping roller 47 and are transferable, in particular slidable. They can be transferred uniformly relative to each other or together. They are used to limit the glue in the glue container 48 in the lateral space and set the gluing area in the lateral direction of the infinite corrugated intermediate web 20. In order to glue different widths or lateral areas of the infinite corrugated intermediate web 20, the glue dam 49 can be transferred in the lateral direction of the infinite corrugated intermediate web 20. By shifting the glue dams 49, the glue width on the infinite corrugated web 20 or the distance between the glue area on the infinite corrugated web 20 and its longitudinal edge can be adjusted. The position of the glue dams 49 and the distance between them can be adapted to the infinite corrugated web 20 to be glued. Each glue dam 49 is assigned a fifth transfer unit 50 for its transfer ( Figure 3 ). The transfer units 50 can be actuated independently of each other.

[0073] After applying glue to the infinite corrugated intermediate web 20, each glue dam 49 forms a glue edge 65, which extends adjacent to and parallel to the longitudinal edge 61 of the single-sided laminated corrugated board web 2. Each glue edge 65 is, for example, located between the infinite corrugated intermediate web 20 and the infinite cover web 26. It is therefore covered and forms the lateral boundary of the gluing area. Instead of a negative pressure source in flow communication with the circumferential groove 44, the glue application device 45 can be under overpressure, so that the infinite corrugated intermediate web 20 is particularly held on the first slotting roller 42 and cleanly rests in its groove. Then there is an overpressure source. A pressure gradient or pressure difference is essential, which can be achieved by a corresponding pressure gradient or pressure difference source.

[0074] Then, in the device 1 for producing a single-sided laminated corrugated board web, a smooth endless cover web 26 is connected to an endless corrugated web 20 provided with glue from a glue container 48. In order to press the endless cover web 26 onto the endless corrugated web 20 provided with glue, which in turn rests in the region against the first grooved roller 42, the device 1 for producing a single-sided laminated corrugated board web has a pressing device 51 designed as a pressing belt device or a pressing belt module. The pressing device 51 is arranged above the first grooved roller 42. It has at least two spaced-apart pressing belt deflecting rollers 52 and an endless pressing belt 53 guided around the pressing belt deflecting rollers 52. The first grooved rollers 42 partially engage from below into the space between the pressing belt deflecting rollers 52, whereby the pressing belt 53 is deflected by the first grooved rollers 42. The pressing belt 53 presses on the endless cover board web 26 , which in turn presses on the endless corrugated web 20 , which rests on the first slotting roller 42 to form a single-sided laminated corrugated board web 2 .

[0075] The single-sided laminated corrugated paperboard web 2 is essentially two-layer. It consists of an infinite cover web 26 and an infinite corrugated web 20 ( Figure 2 ). In the region where the endless cover web 26 and the corrugated web 20 overlap one another, the single-sided laminated corrugated board web 2 is two-ply. On its outer side, i.e. at the edges, it is (in each case) single-ply. Figure 3 As shown, in the single-faced laminated corrugated paperboard web 2, a longitudinal edge 61 is formed by an intermediate web longitudinal edge 63, and another longitudinal edge 61 is formed by a cover web longitudinal edge 64. In the case of the single-faced laminated corrugated paperboard web 2, the longitudinal edge 61, the intermediate web longitudinal edge 63, the cover web longitudinal edge 64 and the glue edge 65 are parallel to each other and extend along the single-faced laminated corrugated paperboard web 2. The single-faced laminated corrugated paperboard web 2 may have one or two single-layer edge regions.

[0076] For temporary storage and buffering of the single-face laminated corrugated board web 2, it is supplied by means of an overhead transport device 54 to a storage device of a corrugated board plant, where it is formed into a loop.

[0077] The corrugated board device further comprises a laminated web splicing device (not shown) which is able to produce a laminated web, in particular an infinite laminated web.

[0078] The corrugated board apparatus further comprises a glue unit (not shown) which applies glue to the endless corrugated web 20 of the single-face laminated corrugated board web 2 .

[0079] Downstream of the glue unit, the corrugated board device has a heated pressing device (not shown) which comprises a horizontally running heating table. Adjacent to the heating table is an infinite pressing belt guided by guide rollers. Between the pressing belt and the heating table a pressing gap is formed through which the single-face laminated corrugated board web 2 and the laminated web are guided to form a preferably infinite three-layer corrugated board web.

[0080] If the corrugated board plant comprises more than one device 1 for producing a single-faced laminated corrugated board web, double-faced laminated corrugated board webs can be produced having more than three layers, for example five or seven layers.

[0081] The endless intermediate web 20 is assigned a first transverse position detection device 55, which is arranged between the first splicing device 3 and the device 1 for producing a single-face laminated corrugated board web, in particular between the first splicing device 3 and the deflection roller 37. The first transverse position detection device 55 is therefore arranged downstream of the endless intermediate web 20 or its outlet or output of the first splicing device 3 in the first transport direction 38. In the first transport direction 38, it is located upstream of the endless intermediate web 20 of the slotting device 41. The first transverse position detection device 55 is arranged, for example, above the endless intermediate web 20.

[0082] The endless cover web 26 is assigned a second transverse position detection device 56 which is arranged between the second splicing device 4 and the pressing device 51. The second transverse position detection device 56 is therefore arranged downstream of the endless cover web 26 or its outlet or output opening of the second splicing device 4 in the second transport direction 40. In the second transport direction 40, it is located upstream of the endless cover web 26 of the pressing device 51. The second transverse position detection device 56 is arranged, for example, above the endless cover web 26.

[0083] The single-face laminated corrugated cardboard web 2 is assigned a temperature measuring device 57, which is arranged between the device 1 for producing the single-face laminated corrugated cardboard web and the bridge carrying the storage device. The temperature measuring device 57 is therefore arranged downstream of the pressing device 51 or its outlet in the conveying direction 84 of the single-face laminated corrugated cardboard web 2. It is arranged, for example, near the outlet of the pressing device 51.

[0084] The temperature measuring device 57 is configured as a contactless operating temperature measuring device. It is spaced apart from but adjacent to the single-face laminated corrugated cardboard web 2. The infinite cover web 26 of the single-face laminated corrugated cardboard web 2 faces the temperature measuring device 57. Thus, the infinite corrugated web 20 of the single-face laminated corrugated cardboard web 2 faces away from the temperature measuring device 57. Thus, the temperature measuring device 57 is located on one side of the infinite cover web 26. Optionally, the temperature measuring device 57 is arranged on one side of the infinite corrugated web 20.

[0085] The arrangement further comprises an electronic processing unit 58 .

[0086] The first lateral position detection device 55 and the second lateral position detection device 56 are at least temporarily in signal connection with a processing unit 58. The processing unit 58 receives electrical signals from the lateral position detection devices 55, 56, which are related to the respective current lateral position of the infinite intermediate web 20 or the infinite cover web 26 at the respective lateral position detection device 55 or 56, respectively.

[0087] The temperature measuring device 57 is also at least temporarily in signal connection with a processing unit 58. The processing unit 58 receives from the temperature measuring device 57 an electrical signal relating to the current temperature of the single-face laminated corrugated paperboard web 2 at the temperature measuring device 57.

[0088] The processing unit 58 is at least temporarily in signal connection with the first splicing device 3. In particular, it is at least temporarily in signal connection with the first transfer unit 18 or the second transfer unit 19. If necessary, the processing unit 58 can in particular actuate, in particular control, the first transfer unit 18 or the second transfer unit 19.

[0089] Furthermore, the processing unit 58 is at least temporarily in signal connection with the second splicing device 4. In particular, it is at least temporarily in signal connection with the third transfer unit 35 or the fourth transfer unit 36. If necessary, the processing unit 58 can in particular actuate, in particular control, the third transfer unit 35 or the fourth transfer unit 36.

[0090] Furthermore, the processing unit 58 is at least temporarily in signal connection with the glue application device 45. In particular, it is at least temporarily in signal connection with the fifth transfer unit 50. If necessary, it can actuate, in particular control, the fifth transfer unit 50.

[0091] The signal connection is designed to be wireless or wired.

[0092] The device 1 for producing a single-sided laminated corrugated board web produces a single-sided laminated corrugated board web 2. A two-sided laminated corrugated board web is thereby produced. The temperature measuring device 57 detects, for example, periodically or continuously, two longitudinal edge regions 60 of the single-sided laminated corrugated board web 2. It measures its temperature. The transverse position detecting devices 55, 56 detect or measure, for example, periodically or continuously, the respective current transverse position of the infinite intermediate web 20 or the infinite cover web 26.

[0093] The processing unit 58 evaluates the transverse positions of the infinite intermediate web 20 and the infinite cover web 26 relative to each other detected by the transverse position detection devices 55, 56. In order to determine the transverse deviation or transverse offset of the infinite intermediate web 20 and the infinite cover web 26 relative to each other, i.e. perpendicularly to their transport directions 38 and 40, respectively, it calculates, for example, the difference between the centers of the infinite intermediate web 20 and the infinite cover web 26 relative to the transverse presence. For example, the processing unit 58 is able to determine the transverse offset of the infinite intermediate web 20 and the infinite cover web 26 relative to each other.

[0094] If the processing unit 58 detects a deviation between the actual value and the set value, a corresponding transverse shift of the infinite intermediate web 20 and / or the infinite cover web 26 occurs. For example, the transverse position of the infinite intermediate web 20 and / or the infinite cover web 26 is adjusted to the center. Optionally, an edge-precision adjustment is performed.

[0095] like Figure 3 As shown, the temperature measuring device 57 includes two independent temperature measuring devices 59, each of which is designed as a thermal imaging camera. The temperature measuring devices 59 have the same construction and are spaced apart from each other in the transverse direction of the single-face laminated corrugated cardboard web 2. Each temperature measuring device 59 is capable of detecting a longitudinal edge region 60 of the single-face laminated corrugated cardboard web 2 and measuring its temperature. Each longitudinal edge region 60 is adjacent to an outer longitudinal edge 61 of the single-face laminated corrugated cardboard web 2 and extends in the vicinity thereof. The two longitudinal edges 61 and the longitudinal edge region 60 extend in the conveying direction 84 of the single-face laminated corrugated cardboard web 2. There is a central region of the single-face laminated corrugated cardboard web 2 between them.

[0096] Each temperature measuring device 59 is carried by a carrier device 62, which extends in the transverse or width direction of the single-face laminated corrugated board web 2, i.e. perpendicularly to its conveying direction 84. Each temperature measuring device 59 can be transferred or moved along the associated carrier device 62. It is advantageous if each temperature measuring device 59 is moved back and forth along the associated carrier device 62 for temperature measurement. For example, each temperature measuring device 59 is assigned its own carrier device 62. Alternatively, the temperature measuring devices 59 share a common carrier device 62. The temperature measuring devices 59 can be transferred, for example, independently of one another or synchronously.

[0097] like Figure 4 As shown, according to an alternative embodiment, instead of the transferable temperature measuring device 59, there is a fixed temperature measuring device 57, which extends in the transverse direction of the single-faced laminated corrugated cardboard web 2 and is able to detect at least the longitudinal edge region 60 of the single-faced laminated corrugated cardboard web 2. For example, a single fixed temperature measuring device 57 is provided for this purpose, which extends over the entire width of the single-faced laminated corrugated cardboard web 2. Alternatively, for example, there are two fixed temperature measuring devices 59, which are spaced apart from each other in the transverse direction of the single-faced laminated corrugated cardboard web 2. Each temperature measuring device 59 is arranged to be able to detect the longitudinal edge region 60.

[0098] Refer to the following Figure 5 The operation of the arrangement is described in more detail.

[0099] The temperature measuring device 57 detects the two longitudinal edge regions 60. It measures their temperature.

[0100] In step 66, the second transverse position detection device 56 and / or the temperature measurement device 57 detects a first cover web longitudinal edge 64 of the infinite cover web 26. The first cover web longitudinal edge 64 extends, for example, relative to the arrangement on the drive side. In particular, its transverse position or width position is measured or determined.

[0101] In step 67, the first transverse position detection device 55 and / or the temperature measurement device 57 detects the first intermediate web longitudinal edge 63 of the infinite intermediate web 20. The first intermediate web longitudinal edge 63 extends on the same side of the single-faced laminated corrugated board web 2 as the first cover board web longitudinal edge 64, for example on the drive side. In particular, its transverse position or width position is measured or determined. In the case of the single-faced laminated corrugated board web 2, the first intermediate web longitudinal edge 63 and the first cover board web longitudinal edge 64 extend adjacent to each other.

[0102] In step 68, the temperature measuring device 57 detects a first glue edge 65 in the first longitudinal edge region 60, which first glue edge 65 extends on the same side of the single-faced laminated corrugated cardboard web 2 as the first cover web longitudinal edge 64, for example on the drive side. In particular, its transverse position or width position is measured or determined. In the case of a single-faced laminated corrugated cardboard web 2, the first glue edge 65 extends adjacent to the first intermediate web longitudinal edge 63 or the first cover web longitudinal edge 64, respectively.

[0103] In step 69, the second transverse position detection device and / or the temperature measuring device 57 detects a second cover web longitudinal edge 64 of the infinite cover web 26. The second cover web longitudinal edge 64 extends, for example, relative to the arrangement on the operator side. It extends opposite to the first cover web longitudinal edge 64. In particular, its transverse position or width position is measured or determined.

[0104] In step 70, the first transverse position detection device 55 and / or the temperature measurement device 57 detects the second intermediate web longitudinal edge 63 of the infinite intermediate web 20. In particular, its transverse position or width position is measured or determined. The second intermediate web longitudinal edge 63 extends on the same side of the single-faced laminated corrugated board web 2 as the second cover web longitudinal edge 64, for example on the operator side. In the case of the single-faced laminated corrugated board web 2, the second intermediate web longitudinal edge 63 and the second cover web longitudinal edge 64 extend adjacent to each other.

[0105] In step 71, the temperature measuring device 57 detects a second glue edge 65 in the second longitudinal edge region 60, which second glue edge 65 extends on the same side of the single-face laminated corrugated board web 2 as the second cover web longitudinal edge 64, for example on the operator side. In particular, its transverse position or width position is measured or determined. In the case of a single-face laminated corrugated board web 2, the second glue edge 65 extends adjacent to the second intermediate web longitudinal edge 63 or the second cover web longitudinal edge 64, respectively.

[0106] Steps 66 to 71 occur simultaneously or (slightly) offset in time from one another.

[0107] In step 72 , the difference between the transverse position of the first cover sheet web longitudinal edge 64 detected in step 66 and the transverse position of the first intermediate web longitudinal edge 63 detected in step 67 is calculated by the processing unit 58 .

[0108] In step 73 , the difference between the transverse position of the first intermediate web longitudinal edge 63 detected in step 67 and the transverse position of the first glue edge 65 detected in step 68 is calculated by the processing unit 58 .

[0109] In step 74 , the difference between the transverse position of the second cover sheet web longitudinal edge 64 detected in step 69 and the transverse position of the second intermediate web longitudinal edge 63 detected in step 70 is calculated by the processing unit 58 .

[0110] In step 75 , the difference between the transverse position of the second intermediate web longitudinal edge 63 detected in step 70 and the transverse position of the second glue edge 65 detected in step 71 is calculated by the processing unit 58 .

[0111] Steps 72 to 75 may occur together in time, or may be (slightly) offset in time from one another.

[0112] In step 76, if necessary, the glue dam 49 producing the first glue edge 65 is adjusted accordingly based on the difference calculated in step 73. To this end, the processing unit 58 controls the associated fifth transfer unit 50 accordingly. The glue dam 49 is either moved away from the other glue dam 49 or towards the other glue dam 49.

[0113] In step 77, if necessary, the glue dam 49 generating the second glue edge 65 is adjusted accordingly based on the difference calculated in step 75. To this end, the processing unit 58 controls the associated transfer unit 50 accordingly. The glue dam 49 is either moved away from the other glue dam 49 or towards the other glue dam 49.

[0114] In step 78 , processing unit 58 calculates the difference between the difference calculated in step 72 and the difference calculated in step 74 .

[0115] In step 79, if necessary, the infinite cover web 26 is readjusted accordingly based on the difference calculated in step 78. To this end, the processing unit 58 controls the third and fourth transfer units 35, 36 accordingly. For example, the cover web rolls 22, 24 that have just been moved or unfolded are axially shifted and / or tilted. Then, the second splicing device 4 unfolds the finite cover web 21 or the infinite cover web 26 according to the set specifications, preferably in such a way that in the device 1 for producing a single-sided laminated corrugated board web, the latter can, for example, be connected substantially congruently to the infinite intermediate web 20 or respectively connected centrally with respect to its transverse direction to the infinite intermediate web 20. The processing unit 58 adjusts, in particular, the transverse position of the infinite cover web 26 according to the transverse position of the infinite intermediate web 20. As a result, subsequent edge trimming of the double-sided laminated corrugated board web can preferably be minimized or completely unnecessary.

[0116] Alternatively or additionally, the first and second transfer units 18 , 19 are actuated accordingly, in particular in order to minimize or render edge trimming superfluous.

[0117] Optionally, the lateral position of the infinite intermediate web 20 is adjusted according to the lateral position of the infinite cover web 26 .

[0118] like Figure 6 As shown, in step 80, the first circumferential groove 44 or the course of the circumferential groove 44 on the single-face laminated corrugated board web 2 is detected by means of the temperature measuring device 57. In particular, its transverse position or width position relative to the first grooving roller 42 is measured or determined.

[0119] In step 81, the processing unit 58 calculates the first circumferential groove 44 or the lateral position of the circumferential groove 44, respectively. The first circumferential groove 44 or the lateral position of the circumferential groove 44 may also be known in different ways.

[0120] In step 82 , the processing unit 58 calculates the difference between the first circumferential groove 44 or the lateral position of the circumferential groove 44 detected in step 80 and the first circumferential groove 44 or the lateral position of the circumferential groove 44 calculated in step 81 .

[0121] In step 83, the difference determined in step 82 is used as an offset or transverse shift value of the infinite intermediate web 20 relative to the first circumferential groove 44 or the transverse shift of the circumferential groove 44. The offset value can be determined automatically. The processing unit 58 preferably actuates the first splicing device 3 in such a way that at least one intermediate web longitudinal edge 63, preferably both intermediate web longitudinal edges 63, are arranged transversely offset relative to the circumferential groove 44 of the first grooved roller 42 or offset relative to the circumferential groove 44 along the first grooved roller 42.

[0122] Thus, fully automatic bonding and gluing can be ensured.
