Description

The present invention relates to at least one pivotally arranged web guide during the processing or processing of a web-like material, preferably during the processing or processing of a paper web, cardboard web, plastic web, composite web or woven web. With respect to a web guide device for changing the lateral position of a web-like / endless sheet-like material using a roller, particularly adjusting and / or controlling, the web-guide roller is a web-like material when the web-like material is conveyed. Wrapped at least partially by the material, the lateral position of the web-like material is altered by pivoting the web guide roller around the correction axis and / or the reference axis.

Accurate lateral positioning of the web-like material / material web is crucial in many processing and processing steps such as printing / stamping, longitudinal cutting, embossing or punching. Increased production rates and improved quality requirements require accurate guidance of material webs / sheets throughout the production process. Deviations from the desired lateral position of the material web and variations in lateral position are caused by other effects such as, for example, different web thicknesses, colorant action and / or humidity action, or other effects such as previous processing steps. Can be caused by uneven elongation of.

The web-like material is usually provided on large feed rolls, which are unwound and fed to the processing machine. Correction and / or control and / or adjustment of the lateral position of the material web, i.e., the generation of lateral offsets in the direction across the web extension direction, is performed using pivotally arranged web guide rollers. , The web guide roller is arranged between the supply roll and the processing device. The web guide rollers can be detected by one actuator each at both ends, and these actuators are synchronously reciprocated. In this way, the rollers pivot around their center, thereby preventing changes in web length on only one side and / or actively adjusting / setting the lateral position of the web-like material. Can be done. The lateral offset is determined by the so-called correction angle between the pivot web guide roller and another roller on the upstream or downstream side of the material web in the transport direction. The corresponding rollers can also be pivoted by only a single actuator. In this case, the adjusting stroke can be transmitted in opposite directions to the respective roller ends via the lever and the connecting rod. Corresponding pivot rollers are known from German Patent Application Publication No. 2540923 (A1) and European Patent Application Publication No. 1474226 (A1).

Further, it is known that the web guide device is provided with two web guide rollers arranged parallel to each other and spaced apart from each other. The two web guide rollers can be pivoted independently or synchronously with each other. The two web guide rollers can also be placed on a common frame that can be pivoted around the axis of rotation. The axis of rotation of the frame can, for example, pass through the center of the frame or the axes of rotation of the two web guide rollers. The lateral offset of the material web is a function of the distance between the two pivot web guide rollers and the angle of rotation of the pivot frame.

German Patent Application Publication No. 2540923 (A1) European Patent Application Publication No. 1474226 (A1) German Patent Application Publication No. 3833804 (A1)

An object of the present invention is to improve a web guidance device known by the prior art. In particular, the web guide device shall be characterized by a compact design and high functional density. In addition, reliable and precise control and / or adjustment of the lateral position of the web-like material shall be ensured.

The above object is achieved by a web guide device having the characteristics of claim 1. The advantageous configuration of the present invention is the subject of the dependent claims.

According to the present invention, in the type of web guidance device described above, at least one break / smoothing / break in the stroke between a pivotable web guide roller and preferably another roller following the material transfer direction. Tools are provided. The material is at least partially wrapped around the web guide roller and another roller, whereby the material web is tensioned across the rollers. Breaking tools (Germany: Brechwerkzeug, English: breaking tool, orthodontic tool) can sink to the surface of the material web. The material is pushed in one direction by the break tool and exhibits the break surface and / or alignment surface and break angle and / or lap angle of the break tool. Break tools in particular allow the web-like material to be provided in a stress-free, fully planar and / or flat form, which can be crucial for further processing of the web-like material. This type of storage can provide curvature and / or stress in the material web and / or to the material web, especially when unwinding the web-like material from the storage roll, so that the material web is stress-free and flat. It is not possible to secure a proper position. However, in principle, it may then be necessary to treat the flat material web so that it exhibits a curved orientation, i.e., a bent and / or curvilinear shape.

In either case, a predetermined stress is broken / smoothed / decaled and / or by passing a web-like material with a curved flat side through the break and / or alignment surfaces of the break tool. Will be generated. The material exhibits a break angle in the contact area with the alignment surface, which is determined by the position of the two rolls adjacent to the alignment surface. In particular, a smoothing action occurs, i.e., the web-like material is then available in a flat, planar form. However, as an alternative, it is also possible to thus provide stress and thus curvature in the material web. Depending on the break angle and alignment plane of the break tool, various curvatures and / or stresses can be removed from the web-like material or provided to the web-like material.

Therefore, the present invention is based on the idea that the web guide device can also be used to break the web-like material, i.e., further new functionality is incorporated into the web guide device. Here, the stress tool is incorporated into the web guide so that the lateral position of the web-like material can be changed and the web-like material can be broken.

Surprisingly, with respect to the present invention, it has been shown that breaking the material web, especially for tension release, has a beneficial effect on the lateral position change of the material web caused by the web guide rollers. Breaking the material web in the area between the two web guide rollers results in the material web being guided between the web guide rollers in a flat, planar form, which results in highly accurate lateral positioning of the web-like material. It will be possible. In the case of the web guide device according to the present invention, the stress of the material web resulting from the lateral offset of the material web can also be reduced in the region between the web guide rollers for accurate web guidance and / or web guidance. Control is simplified.

Further, by incorporating the two functional units into the web guidance device, the installation space required for the functions of "web guidance control" and / or "web guidance adjustment" and "break" can be significantly reduced. Due to the compact design of the web guidance device according to the present invention, low machine cost and / or equipment cost can be realized. Since the installation space is small, it is possible to easily change the installation position of the web guide device, which makes the web guide device according to the present invention suitable for a wide range of applications. Incorporating the "break" function into the web guidance device means deviating from the conventional conventional break tool placement in front of the web guidance device.

The lateral offset generated by the web guide device according to the present invention is a function of the correction angle or the pivot angle driven by the pivot web guide roller. The break tool is incorporated into the web guide device and is arranged adjacent to the web guide roller so that the web guide material is broken in addition to changing the lateral position of the web guide material. The web-like material is broken after undergoing a (first) direction correction and / or redirection as it passes through the pivotal web guide roller. After passing through the break tool, the material web is preferably stress-free and flat and can be fed into further processing and / or processing steps. In this context, "no stress" means that when the external force is released, preferably the material web no longer contains stresses that lead to bending, straining or wrapping of the material web. When all external forces are released, especially when the tension acting on the material web during web transfer is released, the material web preferably has a planar form and is preferably no longer stressed.

In order to change the lateral position of the web-like material, the web guide roller can be manually or automatically pivoted by the correction angle or the pivot angle. The web guide rollers can be detected at both ends in the axial direction by one adjusting device, such as a motor or adjusting cylinder, and the adjusting devices are moved in synchronization with each other. In this way, the web guide roller can be pivoted around its center, which allows the lateral position of the web-like material to be adjusted. However, the web guide roller can also be pivoted by a single adjustment device and / or only one actuator. In this case, the rotation can be transmitted in opposite directions to the respective roller ends via the lever and / or the connecting rod. Alternatively, the web guide roller can be pivoted around a rotation axis that does not pass through the center of the web guide roller. Instead of pivoting the web guide roller with at least one adjustment device, the web guide roller can also be manually adjusted by the user.

A sensor device equipped with at least one sensor to detect the lateral position of the web-like material, and a correction angle and / or pivot angle of the web guide roller as a function of the lateral position of the web-like material detected by the sensor. It is useful when a control device and / or a control device designed to control and / or adjust is provided. The sensor device detects the lateral position of the web-like material and transmits this information to the control device and / or the adjustment device. The control device and / or the adjustment device compares the sensor data representing the current data with the stored target data and derives a control command for the pivot web guide roller from the comparison of the two values. The corresponding command is then transmitted by the control device and / or the adjustment device to the pivot web guide roller and / or the adjustment device of the web guide roller. Next, the corresponding correction angle of the web guide roller is set. This provides automatic control and / or adjustment and adjustment of the lateral position of the web-like material. For example, as the sensor, a web edge sensor in the form of an ultrasonic sensor or an optical sensor can be provided. A line scan camera can be used to detect the lateral position of the web-like material.

To change the lateral position of the web-like material, the web guide rollers are pivoted around a correction or pivot axis perpendicular to the axis of rotation of the web guide rollers. The greater the desired lateral offset of the material web and / or the greater the deviation between the current position and the target position of the material web, the greater the correction angle of the web guide roller is set.

The pivot web guide roller can be designed as a heating roller and / or as a cooling roller. This further increases the functional density of the web guide device according to the present invention. Heating rollers and / or cooling rollers are used in a variety of applications. For example, a heating roller can activate the reaction layer. Cooling rollers can be used, for example, to cool the material web.

In a preferred embodiment of the invention, the break tool is also arranged to be mobile and preferably pivotable. Preferably, the web guide rollers and break tools can be rotated around pivot axes parallel to each other. The pivotal placement of the break tools allows, in particular, to align the break tools parallel to the web guide rollers. Therefore, the break tool can be adapted to the lateral offset of the material web caused by the pivotal web guide roller. The break tool can be pivoted automatically or manually.

In another advantageous design, the web guide rollers and break tools are synchronously pivotable. This ensures that, in particular, the web guide rollers and break tools are always parallel to each other. As a result, the effective tension reduction of the material web after passing through the web guide roller is ensured, and the collision between the web guide roller and the break tool between the pivots of the web guide roller can be avoided.

For synchronization adjustment, a mechanical coupling between the web guide roller and the break tool can be provided, which allows a specific correction angle and / or pivot angle of the web guide roller and / or a specific pivot of the break tool. Simplified control and / or adjustment when setting the angle.

According to the present invention, the break tool can be provided between two pivotable web guide rollers arranged continuously in the material transport direction. When the web guide rollers are pivoted upstream and downstream of the web guides, preferably with respect to the non-driven guide rollers, the pivot angle or correction angle of the material web as it passes through the web guides. As a function, it is possible to achieve a specific lateral offset of the material web, the transport direction before the first web guide roller and the transport direction after the second web guide roller can extend parallel to each other and laterally. The offset is also determined by the distance between the web guide rollers. The distance between adjacent web guide rollers can be, for example, 50 to 1,000 mm, preferably 200 to 800 mm, and even more preferably 300 to 400 mm. The distance between adjacent web guide rollers can be further increased, especially for large web widths. In the region between changes in the direction of the material web, according to the invention, the material is broken with a break tool.

A common actuator can be provided for the pivotal movement of the two web guide rollers. This actuator can also be used to pivot the break tool. This facilitates synchronous adjustment and movement of the web guide roller and the break tool in particular. However, the web guide rollers and break tools can also be adjusted by multiple separate actuators. This adjustment can be made electrically, hydraulically and / or pneumatically. A measuring device, a control device and / or an adjustment device can be provided for the integrated adjustment of the web guide roller and the break tool.

Web guide rollers and break tools, and preferably another web guide roller, can be placed on a pivotable frame and thus can be pivoted together. A particular lateral offset of the material web can be achieved by rotating the frame. In addition, the common placement of the web guide rollers and break tools on the frame includes the synchronous adjustment of the web guide rollers and break tools structurally easily and at low cost. Preferably, at least two web guide rollers can be placed on the pivot frame and the break tool can be placed in the transport area between the web guide rollers so that the web guide rollers and the break tool are synchronized pivots. For motion, it is sufficient to rotate the frame by a specific correction angle and / or pivot angle. The use of the pivot frame greatly simplifies the synchronization of the web guide roller and break tool, which is the only single adjustment device for pivoting the web guide roller and break tool through the pivot frame. And / or due to the need for only one actuator. An alternative design can include a pivot frame in which a web guide roller and preferably another web guide roller are located, the frame being movable relative to a stationary break tool. The break tool can be fixed, for example, to a stationary frame wall. For all designs, ensure in all cases that the web-like material can be guided through the break tool so that the desired break action can occur as a result of the web-like material coming into contact with the break tool. It is understood that it needs to be.

The frame can include a fixed lower frame and a pivot upper frame, which can pivot around a rotation axis with respect to the fixed lower frame. The axis of rotation of the frame can be provided in the infeed region of the material web in front of the web guide rollers. With such an arrangement, when the stress of the material web is small, the lateral position of the material web can be changed, and at the same time, an extremely short control compartment can be obtained. As a result, this arrangement is particularly suitable for sensitive materials. However, the axis of rotation can also intersect the transport plane of the material web in the central region between the two web guide rollers and preferably extend through the vertical axis of the break tool.

Preferably, the guide rollers for the material web are provided in front of and / or behind the pivotable frame in the transport direction and can be more preferably non-motivated. The guide rollers should not be mounted on the frame. Therefore, a pivotable frame with web guide rollers and break tools is preferably located between fixed deflection rollers, which provides accurate material supply to the web guide device according to the present invention and generation of lateral offsets. Material discharge is ensured after and after the material breaks.

To break the material, multiple break tools can be provided back and forth in the transport direction of the material web. By using a plurality of break tools, the stress in the web-like material can be gradually reduced or generated. For example, this can be provided to achieve extremely precise and complete smoothing of the material web. Conversely, the use of multiple break tools can also produce higher stresses and / or higher degrees of curvature in web-like materials. In this case, each break tool is preferably on the stroke between two adjacent rollers. Each break tool and the rollers assigned to each break tool preferably face different flat sides of the material web. During the break, the rollers assigned to the break tool apply tension to the material web.

In particular, the web-like material can be broken by using a plurality of break tools on both flat sides, the break tools facing different flat sides of the material web.

The break tool can be designed to be adjustable in order to change the break angle between the web-like material and the alignment plane of the break tool. By adjusting the break tool, the position of the alignment plane with respect to the material web can be changed and / or adjusted / set. By changing the break angle, it is possible to reduce the stress at the time of breaking the material web, or, if necessary, to obtain the stress accumulation in the material web.

By changing the break angle, for example, various smoothnesses of the web-like material can be achieved. In this way, any kind of curvature and / or stress can be provided to the web material. The smaller the break angle between the aligned surface and the web-like material, the greater the stress and / or smoothness that can be achieved from the web-like material. The larger the break angle, the lower the smoothness. Starting from a break angle of about 180 °, there is no deflection of the web-like material at the alignment plane of the break tool and the break action is close to zero.

Preferably, the distance between the alignment plane of the break tool and the plane defined by the two web guide rollers is adjusted / set and / by moving and / or offsetting the break tool with respect to the defined plane. Or it can be changed. This includes an exact alignment plane for the web-like material. This adjustment can be made manually and / or automatically using the adjustment device.

On the other hand, the distance between the break tool and the two web guide rollers in the plane defined by the web guide rollers is such that the break tool is equidistant to both web guide rollers in the transport direction of the material web and vice versa. It can be non-adjustable so that it can be.

It is not excluded that the adjustment of the break tool for changing the break angle is performed by the control device and / or the adjustment device. A sensor device with at least one sensor can be provided, the curvature and / or stress of the material web is detected and / or measured using the sensor, and the adjustment of the break tool to the web guide roller is the measurement data. It is done automatically as a function of.

Therefore, the break tool can only preferably be displaced and / or offset perpendicular to this plane by two adjacent web guide rollers, especially with respect to the plane defined by these vertical axes. Thus, for example, if the web guide is arranged horizontally, the break tool can adjust the height only, for example, in the vertical direction. Therefore, the break angle between the aligned surface and the web-like material can be easily adjusted / set and / or changed by a single setting parameter, which simplifies the adjustment.

In an advantageous design, break tools are provided with break bars, break rolls or break rollers. Suitable breakbars are known, for example, from German Patent Application Publication No. 3833804 (A1). When a break roller is used as the break tool, the diameter of the break roller can be less than 70%, preferably less than 50%, more preferably less than 30% of the diameter of the web guide roller. Advantageously, the break tool can include one or two break rollers supported and mounted by ball bearings. One or more support rolls can also be provided on one or more break rollers. In addition, a suction device can be provided on the break device, which can be used to continuously and / or intermittently remove particles such as dust and paper, especially in the area of the guide surface. The suction device prevents contamination of the web-like material and damage by particles that can accumulate on the guide surface.

Even if not explicitly mentioned in detail, the embodiments of the present invention described above can be combined with each other as needed. The disclosure of the present invention is not limited to the combination of features of the invention specified by the selected paragraph formatting.

Further features of the invention are derived from the following description of the two preferred embodiments of the invention based on the drawings, as well as from the drawings themselves. All of the described and / or drawn features form the subject matter of the invention alone or in any combination, regardless of their combination or relative relationship within the claims.

The present invention will be described in detail below with reference to the drawings.

FIG. 5 is a schematic view of a web guide device according to the present invention provided with two web guide rollers and a break tool arranged between them. FIG. 6 is a schematic view of a web guide device according to the invention comprising two break devices, each disposed between two adjacent web guide rollers.

FIG. 1 shows two web guide rollers 3 and one break device 4 during processing or processing of a web-like material, preferably during processing or processing of a paper web, cardboard web, plastic web, composite web or woven web. The web guide device 1 for changing the lateral position of the web-like material 2 is schematically shown with reference to. The distance A between the two web guide rollers 3 can be 50 to 1,000 mm, preferably 100 to 800 mm, and more preferably 300 to 400 mm with respect to the central vertical axis or the rotation axis. The distance between adjacent web guide rollers can also be increased. In the illustrated design, for example, the lap angle of the material web 2 with the web guide roller 3 is at least 90 °, respectively.

The web-like material 2 is provided, for example, by a feed roll (not shown). The web-like material 2 is fed to the web guide device 1 via at least one guide roller 6.

The two web guide rollers 3 and the break device 4 are arranged on a pivotable upper frame 5. The pivotable upper frame 5 is connected to a fixed lower frame 7 so that it can pivot around the axis of rotation 8. In the illustrated design, the rotating shaft 8 passes through the in-feed region of the web-like material 2 into the web-guide device 1, that is, the web-like material 2 in the region of the first web-guide roller 3 shown on the right side of FIG. Extends in the transport direction 9. However, the design of the web guide device 1 in which the rotation shaft 8 passes through the center of the upper frame 5 between the web guide rollers 3, which preferably coincides with the center of gravity of the upper frame 5, is not excluded. However, the position of the rotating shaft 8 can also be any other position inside or outside the upper frame 5.

A sensor device 11 with at least one sensor is arranged between the web guide device 1 and another guide roller 10 arranged outside the upper frame 5. The sensor determines the current position of the lateral position of the web-like material 2. If the current position deviates from the target position of the web-like material 2 required for the transport process or processing of the web-like material 2, or if the corresponding target position will be set, the corresponding adjustment command Is transmitted by an adjustment device and a control device (not shown) to the adjustment device of the pivotable upper frame 5 which is also not shown. The adjusting device causes a pivotal movement and / or rotation of a pivotable upper frame 5 around a fixed lower frame 7 and adjusts the web guide rollers 3 with respect to the deflection rollers 6 and 10 to form a web-like material. Two specific lateral offsets will be generated.

The break device 4 includes a break tool 12 in the form of a break bar. When the material is conveyed, the web-like material 2 wraps around the web guide roller 3 and tensions are applied to the material web across the roller 3. The alignment surface 13 of the break tool 12 sinks into the plane of the material web. The material is pushed out of its plane by the break tool 12 and exhibits a break angle and / or lap angle 14 with the break surface and / or alignment surface 13 of the break tool 12. When the web-like material 2 is pulled over the break surface 13, the material is broken, which results in, for example, smoothing of the material web. However, in principle, it is also possible to establish a specific stress in the material web by pulling the web-like material 2 over the break surface 13 and thus to achieve a specific curvature of the material web.

Due to the collective arrangement of the break tool 12 and the web guide roller 3 on the pivotable upper frame 5, a constant parallel alignment of the alignment surface 13 with respect to the web guide roller 3 is ensured. In this way, the alignment surface 13 can be optimally adapted to the transport direction 9 of the web-like material 2. In addition, the integration of "web guidance" and "break" functions into a single unit offers space-saving, structurally simple and low-cost potential.

The break angle 14 can be varied by the vertical height adjustment capability of the break tool 12 (characterized by arrow 15 in FIG. 1) as shown in FIG. In height adjustment, the break tool 12 moves perpendicular to the plane defined by the rotation axes of the two web guide rollers 3.

By changing the break angle 14, it is possible to have a particular effect on the particular smoothing of the web-like material 2 when pulled over the alignment surface 13, or to provide a particular stress and / or curvature as needed. It is possible. For example, the larger the break angle 14, the smaller the smoothing of the web-like material 2 achieved by pulling over the alignment surface 13. For example, when the break angle 14 shown in FIG. 1 is about 180 °, no further smoothing and / or break occurs. As a result, the material web 2 is no longer in stressed contact with the alignment surface 13 of the break tool 12. Similarly, the small break angle 14 results in a high degree of smoothing and / or curvature.

The position of the break tool 12 can be changed and / or adjusted manually or automatically. For automatic height adjustment, an adjustment device for electrical, hydraulic or pneumatic operation can be provided. The position of the break tool 12 can also be adjusted, preferably automatically, as a function of stress in the web-like material 2. For this purpose, corresponding measuring devices, control devices and / or adjustment devices can be provided (not shown in FIG. 1).

Further, the design in which the break tool 12 is adjusted along the arrow 16 in the plane defined by the rotation axes of the two web guide rollers 3 is not excluded. The break angle 14 can also be changed by adjusting the break tool 12 in the transport direction 9 of the material web or in the opposite direction.

FIG. 2 schematically shows a different configuration of the web guide device 1. The same reference symbols of design shown in FIGS. 1 and 2 characterize components or assemblies of the same structure and / or function.

In order to change the lateral position of the web-like material 2, the web guide device 1 shown in FIG. 2 includes four web guide rollers 17 and 18. Two break devices 19 and 20 are provided for multiple breaks of the material web. Each break device 19 and 20 includes a break tool 22. The types and designs of break devices 19 and 20 can correspond to the types and designs of break devices 4 shown in FIG. 1 and described above.

The web guide rollers 17 and 18 and the break devices 19 and 20 are arranged on the upper frame 5. The upper frame 5 is pivotally connected to a fixed lower frame 7 around a rotating shaft 8. A particular lateral offset of the web-like material 2 can be achieved by the pivot of the upper frame 5. In the design shown in FIG. 2, the rotary shaft 8 can be located in the material entry region into the web guide device 1, that is, in the transport direction 21 of the web-like material 2 in front of the first web guide roller 17.

The first front break device 19 is arranged between the web guide rollers 17 in front of the transport direction 21. The second break device 20 is arranged between two web guide rollers 18 arranged on the downstream side. As described above, each break tool 22 is assigned to the pair of web guide rollers 17 and 18, and the break tool 22 and the web guide rollers 17 and 18 assigned to the break tool 22 are different from each other in the web-like material 2. Facing the flat side. When the material is transported, the web-like material 2 wraps around each pair of rollers, thereby tensioning the material web across the web guide rollers 17 and 18. The aligned surface of each break tool 22 sinks into the plane of the material web between the web guide rollers 17 and 18.

Each of the two break tools 22 acts on the opposite flat side of the web-like material 2. In this way, smoothing can be achieved from both sides. Alternatively, it is possible to apply stress and thus curvature to the web-like material 2 from both sides.

To change the break angle 14, the break tool 22 can be adjusted perpendicular to the plane placed by the adjacent web guide rollers 17, 18, i.e. left and / or right in FIG. For this, the break devices 19 and 20 can be adjusted manually or automatically.

Control devices and / or adjustment devices (not shown) are provided to change the lateral position of the web-like material 2, in particular to control and / or adjust. When the web-like material 2 exits the web-guide device 1, if the sensor 11 of the control device and / or the adjustment device detects a deviation of the current lateral position from the target position of the web-like material 2, the corresponding control command and / or Alternatively, an adjustment command is generated and sent to an adjustment device (not shown). The adjusting device pivots the upper frame so that the lateral position of the web-like material 2 changes to a desired degree.

In principle, the web guide device 1 can also include three or more break devices 19, 20 each having an assigned pair of rollers.
