Technical Field

The invention relates to a walkway (Laufsteg) for installation on a machine, in particular a machine for producing, processing or treating a fibrous material web, comprising a walkway floor which is connected at least on the boundary side to a walkway cheek (Laufstegwange), preferably designed as a hollow profile, and which comprises at least two railing columns connected to the walkway cheek, on which railing is fastened.

Background

Such walkways are known. Document DE 202012104986U 1 discloses a walkway for a fiber web machine with a walking plane and two strut members which are arranged laterally on the walking plane and spaced apart from each other so as to form a gap for accommodating the walking plane. The upper post element is implemented in two parts and consists of two halves between which the balustrade panel is clamped in order to construct the balustrade.

This known embodiment is costly, less flexible and has to be dimensioned and configured for each station in the fiber web machine. This means a large part diversity for large machines with multiple walkways.

Disclosure of Invention

The object of the invention is therefore to provide a low-cost and safe walkway which is constructed substantially in a modular manner and whose components can be used and arranged at least in part in a flexible manner.

The present invention solves the above technical problems. In the invention, a walkway for installation on a machine, in particular a machine for producing, processing or treating a fibrous web, is provided, which includes a walkway base plate which is connected at least on the boundary side to a walkway cheek, preferably designed as a hollow profile, and which includes at least one railing post on which a handrail is fastened. The invention is characterized in that the walkway cheek has on its upwardly facing side a cross-sectional profile, preferably extending over the entire length in the longitudinal direction of the walkway cheek, for a slidable, form-fitting connection with at least one clamping element having a complementary profile.

The walkway cheek with the clamping element is preferably arranged on the boundary side of the walkway base plate facing away from the machine, that is to say on the outside. In the case of certain applications, however, at least the walkway cheeks can also be arranged on the inside of the walkway base plate.

The connection between the walkway cheek and the at least one clamping element is established by using mutually engaging, complementary profile shapes. The connection is made such that the clamping element is mounted slidably along the walkway cheeks and maintains a form-fitting connection there. The component, for example the at least one clamping element, can thus be flexibly used for different stations on the machine or reused when being rebuilt, and without the need to construct and manufacture new components or to perform mechanical machining (e.g. drilling, tapping) on the component. The adjustment of the balustrade (e.g. the distance between the balustrade posts) can be performed without changing the walkway cheeks and maintaining the safety function of the balustrade.

A further advantage is that the clamping element is arranged above the walkway cheek. The plane of the walkway cheek assigned to the walkway base and the outer surface opposite the walkway base thus do not have a projecting bracket for the railing cylinder. This increases the safety of the staff on the one hand and, on the other hand, facilitates the tidiness and the maintenance of the machine.

In an advantageous practical embodiment, the connection between the at least one clamping element and the walkway cheek is lockable by clamping. This is beneficial for the fixation after adjustment of the balustrade.

In a preferred embodiment, the at least one clamping element is designed in two parts. The first and second clamping element members are held in position relative to each other by a tensioning element, such as a screw. Whereby a slidable or lockable connection between the at least one clamping element and the walkway cheek can be established with the tensioning element.

The first clamping element component and the second clamping element component of the at least one clamping element can have a positioning element, preferably a tongue and groove. So that the assembly of the at least one clamping element on the walkway cheek is also simplified by the mutually engaging, complementary contour shape.

In a preferred practical embodiment, the at least one clamping element has a receiving opening for a preferably circular newel on the side opposite the complementary contour.

The rail post can be fixed in the receiving opening by clamping and/or by form-fitting.

The at least one clamping element can have a threaded bore for a screw (in particular a threaded pin) provided with a tip in order to establish a form fit.

In other possible embodiments, the newel post has a groove in the region of the screw to establish a form fit.

The walkway cheek is preferably designed to take up the load of the walkway base plate. The load of the walkway base consists of the weight of the walkway base and the additional load when the walkway base is used.

For reasons of static mechanics, it is therefore advantageous if the cross-section transverse to the length of the walkway cheek has a greater height than width.

For safety reasons it is also advantageous when the upper side of the walkway cheek is located above the walkway floor.

The walkway cheek preferably has a cavity for accommodating supply lines and/or data lines. This can be achieved at low cost by applying the cavity profile.

In a possible further development, the walkway cheek has an opening and/or a window for emitting an optical signal on the side facing away from the walkway base plate. Here, colored LED light may be involved. Colors may be assigned meanings. This may be used to inform machine personnel of, for example, the operational status of the machine, impending services, or security conditions.

Accordingly, information elements for displaying text and/or images can be integrated into the walkway cheek. The information element may be an LCD/LED display. This embodiment can also be used to inform machine operators, for example, of the operating state of the machine, of services to be carried out or of safety situations.

In addition, the walkway cheek can be embodied in one piece. This can simplify the construction of the walkway cleats and improve stability.

In a possible design variant, the shape of the cross-sectional profile is designed as a T-profile and the shape of the complementary profile is designed as a C-profile. In other words, the C-profile-like contour of the at least one clamping element encompasses the T-profile-like cross-sectional contour of the walkway cheek. When the clamping element is locked on the walkway cheek, the tensioning element is tightened, in other words tightened, until a clamping is produced by the C-profile-like profile and the T-profile-like cross-sectional profile.

In an alternative embodiment, the cross-sectional profile is in the form of a C-profile and the complementary profile is in the form of a T-profile. In other words, the C-profile cross-sectional contour of the walkway cheek encompasses the T-profile contour of the at least one clamping element. When the clamping element is locked on the walkway cheek, the tensioning element of the at least one clamping element is tightened, in other words at least one clamping element is spread, until a clamping is produced by the T-profile-like profile and the C-profile-like cross-sectional profile.

The walkway cheek may be composed of aluminium or stainless steel.

Detailed Description

Fig. 1 shows a part of an embodiment of a walkway 1 according to the invention in a simplified three-dimensional schematic view. The walkway 1 is suitable and designed for assembly on a machine for manufacturing, processing or treating a fibrous web. The walkway comprises a walkway base plate 2 in a horizontal plane, which is connected at least on the boundary side to a walkway cheek 3 designed as a hollow profile. The walkway cheek 3 extends with its long side in the longitudinal direction 5. The hollow profile has a cavity 6. More than one cavity 6 can be designed according to the embodiment shown in fig. 2. The cavity 6 extends in the longitudinal direction 5. The walkway 1 also comprises at least one railing post 9 to which a handrail (not shown) is fixed. The side of the walkway cheek 3 facing upwards has a cross-sectional profile 4, preferably extending over the entire length of the walkway cheek 3, for a slidable, form-fitting connection with at least one clamping element 7 having a complementary profile 8. The walkway cheek 3 with the clamping element 7 is preferably arranged on the boundary side of the walkway base plate 2 facing away from the machine, that is to say on the outside. In certain applications, however, at least the walkway cheeks 3 can also be arranged on the inside of the walkway base plate 2, that is to say on the side facing the machine. In the example shown, only a band-shaped lamella is arranged on the inner side. In practice, the walkway 1 can have a plurality of clamping elements 7 each having a railing post 9.

By applying or designing the cross-sectional profile 4 and the complementary profile 8 as mutually engaging, complementary profile shapes, a connection between the walkway cheek 3 and at least one clamping element 7 is established. The connection is made such that the clamping element 7 is mounted slidably along the walkway cheek 3 and maintains a form-fitting connection there. The component, for example the at least one clamping element 7, can thus be used flexibly for different stations on the machine or reused in a retrofit, and no new component has to be constructed and manufactured. The connection between the at least one clamping element 7 and the walkway cheek 3 is lockable by clamping. For this purpose, the at least one clamping element 7 is implemented in two parts. The two clamping element members 7.1, 7.2 are held in position relative to each other by means of a tensioning element 13, for example a screw in this example. A slidable or lockable connection between the at least one clamping element 7 and the walkway cheek 3 can thus be established by means of the tensioning element 13. After adjustment of the balustrade, locking is beneficial for fixing. Adjustment of the balustrade, for example changing the distance between the balustrade posts, can be carried out without changing the walkway cheeks 3 and maintaining the safety function of the balustrade, because the clamping element is slidable after the clamping of the tensioning element on the clamping element 7 is released, while the form fit between the cross-sectional profile 4 and the complementary profile 8 is maintained. The clamping element 7 is arranged above, that is to say on the upper side of, the walkway cheek 3. The plane of the walkway cheek 3 associated with the walkway base 2 and the outer surface opposite the walkway base are thus free of projecting brackets for the railing posts 9, which may be in danger of tripping. This design increases the safety of the staff on the one hand, and on the other hand facilitates the tidiness and keeping clean of the machine. The two clamping element components 7.1, 7.2 of the at least one clamping element 7 have positioning elements 11, 12, preferably a tongue and groove and a tongue (or key). The assembly of the at least one clamping element 7 on the walkway cheek 3 is thereby also simplified due to the mutually engaging, complementary profile shapes. The at least one clamping element 7 has a receiving opening 10 for a circular rail post 9 on the side opposite the complementary contour 8. The rail post 9 is fixed in the receiving opening 10 by clamping and by form fit. For this purpose, the clamping element 7 has a threaded through-hole 14 for a screw provided with a pointed end. When the screw is tightened, the tip is pressed onto the newel post 9 and thereby establishes a clamping on the one hand and a form fit on the other hand. If a screw with a blunt end is used, only clamping can take place. It is also possible to adapt the size of the receiving bore 10 to the newel 9 so that when tensioning the two clamping element members 7.1, 7.2, the newel 9 is clamped by the tensioning element 13. The walkway cheek 3 is dimensioned to be able to bear the load of the walkway floor. For reasons of static mechanics, the cross-section transverse to the length of the walkway cheek has a greater height than width. Thereby increasing the bending strength. For safety reasons, the upper side of the walkway cheek 3 is located above the walkway floor. Thereby preventing the falling of the parts placed on the walkway floor. The walkway cheeks 3 are embodied in one piece. The walkway cheek 3 consists of aluminium.

Fig. 2 shows an exemplary cross-sectional shape transverse to the longitudinal direction 5 of a first embodiment of the one-piece walkway cheek 3 in a simplified three-dimensional illustration. The walkway cheek 3 has a plurality of cavities 6, which extend in the longitudinal direction 5. The cavities are spaced from one another by a partition. The partition plate improves the stability of the extrusion type profile. The cross-sectional contour for accommodating the clamping element is placed on the upper side of the walkway cheek 3. The shape of the cross-sectional profile is designed as a T-profile and the adapted shape of the complementary profile of the clamping element 7 as a C-profile, as shown in fig. 4 and 5.

Fig. 3 shows a section of an exemplary second embodiment of the walkway cheek in a simplified three-dimensional illustration. It differs from the embodiment according to fig. 1 to 3 in that an information element 17 for the playback of text and/or images is integrated into the walkway cheek 3. The information element 17 may relate to an LCD/LED display. This embodiment can also be used to inform machine operators, for example, of the operating state of the machine, of services to be performed or of safety situations

Fig. 4 shows a section of an exemplary third embodiment of the walkway cheek 3 in a simplified three-dimensional illustration. In this embodiment, the supply line 15 and/or the data line 15 pass through the cavity 6. Furthermore, the walkway cheek 3 has three openings 16 and/or windows 16 for transmitting optical signals on the side facing away from the walkway base plate 2. In this case, colored LED light may be involved. Colors may be assigned meanings. This may be used to inform machine personnel of, for example, the operational status of the machine, impending services, or security conditions.

Fig. 5 shows a simplified three-dimensional illustration of a first exemplary embodiment of a two-part clamping element 7. A complementary contour 8 embodied in the shape of a C-profile is placed on the underside of the clamping element 7. The clamping element has positioning elements 11, 12, which enable positioning of the two clamping element components 7.1, 7.2 in the vertical direction. This can be achieved by complementary projections and retractions on the joining faces of the two clamping element members 7.1, 7.2.

The second exemplary embodiment of the two-part clamping element shown in a simplified three-dimensional representation in fig. 6 differs from the first exemplary embodiment in fig. 5 by the embodiment of the positioning elements 11, 12 on the one hand and by the threaded bores for receiving screws for clamping the rail post 9 in the receiving bore 10 on the other hand. The first clamping element component 7.1 has a tenon as a positioning element, while the second clamping element component 7.2 has a mortise. In addition, the tensioning element 13, which is embodied as a screw, is shown in a partial schematic view.
