TRANSPORTATION DEVICE

Description

[0001] The invention relates to a transport device for transporting goods in a transport direction according to the preamble of claim 1.

[0002] Conveyor devices of this type are used in the beverage industry for transporting individual items and generally comprise a multitude of transport elements, each forming a closed loop and driven in a continuous motion, particularly in the form of transport chains or hinged belt chains. Such transport devices are well known to those skilled in the art. The transport elements, with their upper length supported against at least one sliding guide, each form the common horizontal or substantially horizontal transport plane or surface upon which the transported goods rest with their base or standing surface.

[0003] These transport devices are in particular carriers in the beverage industry, which, for example, have a capacity of more than 10,000, preferably more than 50,000 transported items, such as containers, per hour.

[0004] Therefore, such transport devices typically comprise a frame or machine structure on which the transport elements are mounted, held, and / or guided. Individual frames are generally adapted to specific grid dimensions with regard to their respective length and / or width, allowing individual frames to be combined and the individual machines of a complete production plant within the beverage industry to be interconnected. For this purpose, the frames have a base support to which profile elements such as M-profiles, U-profiles, flat profiles, tubular profiles, and especially C-profile elements are arranged. The transport elements, preferably transport chains, run along the top surface of these profile elements, being moved continuously by drive motors and guided by sliding action on the profile elements.

[0005] It is also known to provide sliding elements, in particular sliding strips, to reduce the coefficient of friction between the profile elements and the transport elements, forming a covering for the transport elements with a low coefficient of friction in order to reduce wear on and the driving forces required for the transport elements.

[0006] In the current state of the art, the individual components of the machine frame of the transport device are connected to each other using screw connections, which is very time-consuming and therefore expensive for assembly.

[0007] From publication FR 2915474 A1, a conveyor belt support device is known, comprising a frame, at least one sliding shoe forming a support surface for the belt, wherein the sliding shoe or shoes are supported by the frame; fastening means for the sliding shoe or shoes on the frame, wherein the fastening means comprise a guide connected to the sliding shoe, a wedge engaging in the guide and cooperating with the frame to fix the sliding shoe in at least one direction, and a pin engaging in the guide and cooperating with the wedge to lock the wedge along the length of the guide in at least one direction. FR 1915474 A1 also discloses a transport device according to the preamble of claim 1.

[0008] Furthermore, WO 91 / 17 938 A1 discloses a conveyor belt support device comprising one or more elongated impact arrangements located below the upper running of a conveyor belt and extending longitudinally in the direction of movement of the conveyor belt, each arrangement comprising a support beam, an elastomer layer attached to the upper surface of the conveyor belt support device, and an elongated friction block arranged on the elastomer layer. The upper surface of the friction block is in sliding contact with the underside of the upper running of the conveyor belt. This document is particularly distinguished by the fact that the lateral position of the friction block is arranged by guides extending from the support beam and slidably engaging in one or more longitudinal grooves in the friction block, such that they allow vertical movement of the friction block relative to the support beam as the elastomer layer.

[0029] Identical reference numerals are used in the figures for identical or similarly functioning elements of the invention. Furthermore, for the sake of clarity, only those reference numerals necessary for describing the respective figure are shown in the individual figures.

[0030] The exemplary transport device, generally designated 100 in the figures, is used in particular for transporting goods 102 in at least one transport direction A between container handling machines and / or transfer stations and / or interchange stations (not shown in detail) for the packaging and / or beverage industry. The transport device 100 advantageously has a capacity of more than 10,000, preferably more than 50,000, transported items 102, for example containers, per hour.

[0031] In particular, the transport device 100 comprises at least one transport element 103 forming a closed loop and driven continuously in the transport direction A, which can be designed, for example, as a transport belt, transport chain, hinged belt chain or transport mat. The transport element 103 forms with its upper end, which faces at least one, in the Figure 2The length of the sliding rail 113 supporting a horizontal or substantially horizontal transport plane or surface TE, as shown in more detail, is defined by a horizontal or substantially horizontal transport plane or surface TE on which the transported goods 102 rests with its base or its standing surface. Several transport elements 103, for example two, three, four or more, can also be provided, which are arranged adjacent to one another in a multi-stage manner, i.e., transversely or perpendicularly to the transport direction A, such that the several transport elements 103 form the common transport plane TE with at least a part of their respective upper lengths of their corresponding loops, on which the transported goods 102 can rest at least partially with their base surface.

[0032] At its front end 1.11 and rear end 1.12, both relative to the transport direction A, the at least one transport element 103 is guided by deflection devices 141 and 142, respectively. Specifically, the at least one transport element 103 is guided at its front end 1.11 by a front deflection device 141 and at its rear end 1.12 by a rear deflection device 142. A transport path TS for the transported goods 102 is formed between the front and rear deflection devices 141 and 142 by means of the at least one transport element 103. The transport path TS, on which the transported goods 102 can be transported, is thus formed, in particular, from the rear deflection device 142 in the transport direction A to the front deflection device 141.

[0033] It can also be provided that the front and / or the rear deflection device 141, 142 is designed to be driven by a motor. For example, the front and / or rear deflection device 141, 142 can be designed as an electric motor, preferably as a gearless electric motor, for example in the form of a direct-drive electric motor, preferably in the form of a stepper motor, a servo motor or a torque motor.

[0034] Furthermore, the transport device 100, as shown in the Figure 1 Only schematically indicated, a machine frame 1.10 forms a scaffold on which all components of the transport device 100 are arranged or mounted, and by means of which the transport device 100 stands on a ground surface BE via support elements 101 or legs. As can be seen in particular from the Figure 2As can be seen in more detail, the machine frame 1.10 has at least one base support 111 extending across the entire width of the transport element, i.e., transversely to the transport direction A, to which two support elements 101 are fixedly arranged. The base support 111 forms a support element, for example, a U-profile beam made of stainless steel. Preferably, the machine frame 110 comprises two or more base supports 111, which are distributed along the entire length of the transport path TS, for example, at uniform intervals, and which are each supported on the ground surface BE by at least two support elements 101. Advantageously, at least one base support 111 is provided in the region of the front end 1.11 and at least one further base support 111 is provided in the region of the rear end 1.12 of the transport device 100.

[0035] The base support 111 has, in particular in a flat surface section 23, which can be formed, for example, by one of the legs of the base support 111 designed as a U-profile support, a pre-drilled hole 20 with a geometry deviating from a circular shape. Figure 5b The schematic top view shows a partially depicted flat surface section 23 of a base support 111 with a pre-drilled hole 20. In particular, the pre-drilled hole 20 can be mirror-symmetrical and have two identical circular arc sections 20.1 and two identical rectangular sections 20.2.

[0036] As can be seen in particular from the Figure 2 As can be seen, the base support 111 extending transversely to the transport direction A can also have several pre-drilled holes 20, which are essentially each provided below a corresponding sliding strip 113.

[0037] The at least one transport element 103 is guided to slide on at least one slide rail 113 along the transport path TS, wherein the at least one slide rail 113 is provided in a plane parallel or substantially parallel below the transport plane TE. Advantageously, however, several slide rails 113 are provided, particularly advantageously along the entire transport path TS along which the transport element 103 is moved. Several slide rails 113 can be provided both transversely and longitudinally to the transport path TS below the transport element 103. For example, as shown in the Figure 2 As shown, four sliding rails 113 arranged transversely to the transport route TS are provided, which in their respective longitudinal extent are essentially parallel to each other, i.e. in the transport direction A .

[0038] Multiple sliding rails 113 can be provided not only transversely but also longitudinally along the transport track TS, preferably positioned directly adjacent to one another along the entire length of the transport track TS. Furthermore, it is advantageous for the sliding rails 113 provided longitudinally along the transport track TS to be arranged in a mutually aligned manner, such that a straight, adjacent row of sliding rails 113 is formed. It is also preferred that the sliding rails arranged side-by-side and adjacent to one another in width are also aligned with each other.

[0039] Preferably, the sliding strips 113 have a surface on their upper side facing the transport element 103 that has a low coefficient of friction, which may in particular be made of a plastic.

[0040] The at least one sliding strip 113 is arranged at least sectionally along the transport path TS on at least one profile element 112, which in turn is arranged on the at least one base support 111 of the machine frame 110 via at least one quick fastening device 2 according to the invention.

[0041] The at least one profile element 112 can have a substantially C-shaped cross-section. The at least one profile element 112 has three leg sections: a central leg section 22.1 and two lateral leg sections 22.2. The slide rail 113 is preferably fixedly arranged on the central leg section 22.1, for example, by screwing or gluing. Such profile elements 112 are known to those skilled in the art in the field of transport devices 100 in the beverage industry as C-profile elements. They extend in a parallel plane below the plane spanned by the slide rails 113 and thus also in a plane below the transport plane TE. The longitudinal extent of the cross-section of the lateral leg sections 22.2 is similar to that of the central leg section 22.1.1 oriented at an angle, preferably less than 90°, such that the respective free ends 22.3 of the two lateral leg sections 22.2 would converge at an acute angle in cross-section along an imaginary extension of the free ends 22.3. The middle and the lateral leg sections 22.1, 22.2 define in their cross-section a recess 21, which is open downwards, i.e., in the direction of the support body 111, and accessible from there. The recess 21 thus forms a groove which in its cross-section forms a kind of truncated cone, i.e., it tapers on the side facing away from the sliding rails 113 with the two lateral leg sections 22.2. The middle leg section 22.1 has a width transverse to the transport direction A that corresponds to the cross-section of the . Figure 2The width shown corresponds to at least one sliding strip 113. The sliding strip 113, which is essentially rectangular on its upper surface in a top view (not shown), can have a length in the transport direction A that corresponds to the length of the profile element 112. The profile element 112, in particular its central leg section 22.1, can also be essentially rectangular in a top view (not shown).

[0042] According to the invention, it is provided that at least one profile element 112 is arranged on a base support 111 of the machine frame 110 via at least one quick-fastening device 2, wherein the quick-fastening device 2 is designed for the detachable connection of the profile element 112 with the base support 111.

[0043] Preferably, the quick-fastening device 2 is adjustable between a locking position VP and a release position FP, such that in the locking position VP the quick-fastening device 2 connects the profile element 112 firmly - but releasably - to the base support 111 and in the release position FP releases it again.

[0044] According to the invention, the quick-fastening device 2 has two opposing fastening sections, BA1 and BA2, extending along a central longitudinal axis MA of the quick-fastening device 2, with which the profile element 112 and the base support 111 can be connected. In particular, a first fastening section BA1 is provided, which can be connected to the profile element 112, and a second fastening section BA2, which can be connected to the base support 111.

[0045] Preferably, the first and / or second fastening section BA1, BA2 is designed for force-fit and / or form-fit connection in the locking position VP of the quick fastening device 2.

[0046] It can also be provided that the first fastening section BA1 is inserted into the base carrier 111 in the locking position VP. In particular, the first fastening section BA1 can be inserted into the pre-drilled hole 20 of the base carrier 111 in the locking position VP.

[0047] It can therefore also be provided that the first and / or second fastening section BA1, BA2 is snapped into the profile element 112 and / or the base support 111 in the locking position VP. In particular, the first and / or second fastening section BA1, BA2 can have a locking element 25 for this purpose, which is snapped into the pre-drilled hole 20 of the base support 111 and / or the recess 21 of the profile element 112 in the locking position VP.

[0048] Furthermore, it can also be provided that the first fastening section BA1 is firmly connected to the base carrier 111 in the locking position VP by the first fastening section BA1 engaging the pre-drilled hole 20 of the base carrier 111 with a locking element 25.

[0049] Preferably, the quick-fastening device 2 is rotatable about a central longitudinal axis MA between a locking position VP and a release position FP, such that in the locking position VP the quick-fastening device 2 firmly – but releasably – connects the profile element 112 to the base support 111 and in the release position FP releases it. The quick-fastening device 2 is particularly preferably designed as a rotary locking device that establishes a force-fit and / or positive-locking connection in the locking position VP.

[0050] Two additional components or parts can also be detachably arranged, in particular detachably connected or attached, directly or indirectly to the machine frame 110 of the transport device 100 by means of the quick-fastening device.

[0051] These components can be, for example, electrical components such as repair switches and / or sensors. They can also be mechanical components such as mirrors for light barriers and / or brackets for railings for guiding containers and / or mounting plates for attaching further components and / or mounting strips for attaching further components and / or switch boxes for housing electrical circuits.

[0052] An example in this context is the Figure 3One embodiment is shown in which a retaining element 116, in particular a retaining plate or a retaining strip, with a guide rail 117 attached thereto for the transported goods 102, is detachably fastened to the machine frame 110, in particular to a right and / or left scaffold plate 114, 115 provided on the machine frame 110, by means of the quick-fastening device 2. The quick-fastening device 2 is thus detachably engaged with the scaffold plate 115 by its first fastening section BA1 and with the retaining element 116 by its second fastening section BA2.

[0053] More details are provided in the exemplary embodiment of the Figure 2Several, in particular four, quick-fastening devices 2 are shown, each detachably connected by its first fastening section BA1 to a common base support 111 and by its second fastening section BA2 to a profile element 112. A sliding rail 113 can be provided on the upper side of each profile element 112, which can be fixedly connected to the respective profile element 112, in particular by screwing, soldering, gluing or welding. The transport element(s) 103 rests on the sliding rail(s) 113 and is guided sliding over the upper side of the sliding rail(s) 113. In addition, a right and left scaffold plate 114, 115 are provided on each side of the base support 111. Preferably, the profile elements 112 and / or the sliding rail(s) 113 and / or the scaffold plates 114, 115 extend over the entire length of the transport section TS and can be formed in one piece or, preferably, in multiple parts.

[0054] The Figure 4 Figure 1 shows a schematic side view of an embodiment of the quick-fastening device 2 according to the invention in a locking position VP, in which the profile element 112 is detachably connected to the base support 111 by means of the fastening device 2. In the Figure 4 In the side view shown, the quick-fastening device 2 spans a central plane ME through the central longitudinal axis MA, which is oriented perpendicular to the drawing plane, i.e., the side view shown.

[0055] In particular, the first fastening section BA1 with the base carrier 111 and the second fastening section BA2 with the profile element 112 are in a detachable effective engagement, so that the base carrier 111 can be connected to each other via the first fastening section BA1 and the profile element 112 via the second fastening section BA2.

[0056] Furthermore, the first fastening section BA1 has a free-end first locking section VA1 and / or the second fastening section BA2 has a second locking section VA2 by means of which the base carriers 111 can be held firmly in the locking position VP via the quick-fastening device 2 and released from the quick-fastening device 2 in the respective release position FP.

[0057] According to the design variant of the Figure 4The base carrier for detachable clamping fastening has at least in a section 23 that is at least partially flat a pre-drilled hole or opening 20 which deviates from the circular shape, the cross-section of which is adapted to the longitudinal section of the first locking section VA1, in such a way that the first locking section VA1 can be passed through the pre-drilled hole 20 and the quick-fastening device 2 can be clamped to the base carrier 111 by rotation about the central longitudinal axis MA with the first fastening section BA1.

[0058] Furthermore, the first fastening section BA1 can, in addition to the free-end first locking section VA1, have a first mounting section AL1 extending along the central longitudinal axis MA in the direction of the second fastening section BA2, which forms a receiving groove 24 preferably extending perpendicular to the central longitudinal axis MA. In particular, the first mounting section AL1 can be provided directly adjacent to the second fastening section BA2, and especially arranged on it.

[0059] The receiving groove 24 is provided at least partially circumferentially around the central longitudinal axis MA, preferably fully circumferentially around the central longitudinal axis MA, and forms a contact surface AF for the profile element 112 in the locking position VP on the surface section facing the base support 111. In particular, the receiving groove 24 is dimensioned to match the pre-drilled hole 20 such that the receiving groove 24 does not extend through or pass through the pre-drilled hole 20 in the locking position VP, but rather is supported on the flat section 23 on the side facing the second fastening section BA2, at least partially circumferentially around the pre-drilled hole 20, and in particular comes into contact with it.

[0060] Furthermore, the first fastening section BA1 in the first locking section VA1 has at least one locking element 25, which is provided on a pipe section 27 coaxially enclosing the central longitudinal axis MA and extends radially outwards from the central longitudinal axis MA and can be designed as a locking finger. Advantageously, several, in particular two, locking elements 25 are provided, which are provided on preferably opposite sides of the pipe section 27 and each extend radially outwards from the central longitudinal axis MA and are preferably each designed as a locking finger. The longitudinal extent of the section 27 can be adapted to the thickness of the base support 111 to be locked.

[0061] The at least one locking element 25 has a contact surface 25.1 on its upper side facing the second fastening section BA2, oriented obliquely, in particular at an acute angle to the central longitudinal axis MA, as can be seen in particular from the Figure 5a can be removed.

[0062] In the locking position VP, the at least one locking element 24 is passed through the pre-drilled hole 20 and is rotated relative to the base carrier 111 by preferably 40° degrees from the release position FP to the locking position VP, such that the at least one locking element 25 engages behind the pre-drilled hole 20 and is supported on the flat section 23 on the side facing away from the second fastening section BA2, at least partially around the pre-drilled hole 20, in particular by contact.

[0063] In more detail, the inclined contact surface 25.1 of the at least one locking element 25 comes into clamping and contact-locking contact with the flat section 23 of the base carrier 111 on the side facing away from the second fastening section BA2 by the rotation of the first locking section VA1, such that the base carrier 111 is pressed against the contact surface AF of the receiving groove 24 in the flat section 23 on the side facing the second fastening section BA2 and the flat section 23 is held clampingly between the contact surface AF and the inclined contact surface 25.1.

[0064] As can be seen particularly from the in Figure 5bAs can be seen in the schematic top view of the partially depicted flat surface section 23 of the base support 111, the pre-drilled hole 20 provided therein has a geometry in the cross-section of the top view that deviates from a circular shape. In particular, the pre-drilled hole 20 can be designed to be symmetrical and have two identical circular arc segments 20.1 and two identical rectangular segments 20.2, which are geometrically adapted to the first locking section VA1 such that the first locking section VA1, in particular the at least one locking element 25, can be passed through the rectangular segments 20.2 and is blocked from being pulled out of the pre-drilled hole 20 by the circular arc segments 20.1 in the locking position VP by means of the 40° rotation. The pre-drilled hole 20 in the flat surface section 23 can be produced, for example, by laser cutting, punching, or drilling.

[0065] The flat surface section 23 of the base support 111 has a planar, i.e., flat, upper surface 23.1 facing the second fastening section BA2, and a planar lower surface 23.2 facing away from the second fastening section BA2. In particular, the upper surface 23.1 and lower surface 23.2 span parallel or substantially parallel planes within the flat surface section 23. In other words, the flat surface section 23 has a constant or approximately constant surface thickness.

[0066] According to the design variant of the Figure 4The profile element 112 includes at least one profiling section 22 forming a recess 21, the cross-section of which is adapted to the cross-section of the second locking section VA2, such that, for the releasably clamping attachment of the second fastening section BA2 to the profile element 112, the second locking section VA2 can be received at least section by section in a form-fitting and / or force-fitting manner in the recess 21 by rotating the second locking section VA2 about the central longitudinal axis MA.

[0067] The quick-fastening device 2 has a clamping element 30 in its second locking section VA2, which, in its top view, i.e., perpendicular to the central plane ME, is essentially oval and tapers towards the first fastening section BA1, i.e., has a smaller oval diameter compared to the first section. Thus, the clamping element 30 has its greatest length L in the lateral cross-section of its locking position VP at its free end section 30.1, which faces the second component BT2. In particular, the clamping element 30, which is essentially oval in its top view, has straight contact surfaces 30.2, 30.3 on at least two preferably opposite sides in the region of the free end section 30.1. These contact surfaces allow the clamping element 30 to clamp against the corresponding inner surfaces of the two lateral leg sections 22.2 in its locking position VP, thereby forming a clamping fit.The two lateral leg sections 22.2 are designed to be elastically deformable in such a way that when the system surfaces 30.2, 30.3 of the clamping body 30 are rotated from the release position FP to the locking position VP, they are deflected outwards, i.e. away from the central plane ME - i.e., they give way elastically.

[0068] Between the release position FP and the locking position VP, the second locking section VA2 of the quick-fastening device 2 is preferably rotated by 40° relative to the profiling section 22. Figure 4 This shows in particular the locking position VP, while the Figure 5aThe release position FP is shown. Furthermore, the quick-fastening device 2 can advantageously be designed in one piece, in particular as a single unit, so that if the second fastening section BA2 of the quick-fastening device 2 is rotated, the first fastening section BA1 also rotates, i.e., is rotated from the release position FP to the locking position VP. The first and second fastening sections BA1, BA2 are thus positively connected to each other.

[0069] The clamping body 30 has a width B in the lateral cross-section of the release position FP such that the clamping body 30 can be inserted into the recess 21 formed by the profiling section 22 in its release position FP.

[0070] Furthermore, the clamping body 30 has a length L, i.e., a distance between the opposing contact surfaces 30.2 and 30.3, such that in its locking position VP, the clamping body 30 clamps against the corresponding inner surfaces of the two lateral leg sections 22.2 of the second component BT2, thus creating a clamping fit. The clamping body 30 is also designed such that, by rotating from the release position FP into the locking position VP, it is pressed against the underside of the middle leg section 22.1 and comes into contact with the underside of the middle leg section 22.1 upon reaching the locking position VP, thus establishing a defined position of the fastening device 2 relative to the profile element 112.

[0071] In particular, the length L and width B of the clamping body 30 can be adapted to the profiling section 22, especially to the dimensioning of the middle and the lateral leg sections 22.2.

[0072] As can be seen in particular from the Figure 6a or 6b As can be seen, the quick-fastening device 2 has a through-passage in the form of an opening 28 penetrating the first and second fastening sections BA1, BA2, which in the area of ​​the pipe section 27 may at least partially have an internal hexagon that forms an engagement surface for a tool, for example an Allen key, so that the rotary movement between the release position FP and the locking position VP can be initiated via the tool onto the fastening device 2.

[0073] The Figures 7a to 7bEach figure shows a simplified schematic side view of further design variants of the quick-fastening device 2. This differs from the design variant of the Figures 4 to 6 The respective quick-fastening device 2 is according to the design variants of the Figures 7a and 7bThe assembly is designed in multiple parts. In particular, the first fastening section BA1 is firmly connected to the corresponding second fastening section BA2 by means of an intermediate piece 40. For this purpose, the intermediate piece 40, which acts as a spacer, can be made of solid material and may, for example, have two connecting sections 40.1, 40.2, which may be nose-shaped or tubular, and which engage with the first and second fastening sections BA1, BA2, respectively. The connecting section 40.1, 40.2 can be screwed, glued, soldered, or welded to a corresponding receiving section 50.1, 50.2 of the first and second fastening sections BA1, BA2, respectively. The geometric design of the respective connecting section 50.1, 50.2 can be adapted to the corresponding connecting section 40.1, 40.2, for example, by being designed as a blind hole.

[0074] The circumferential surface U of the intermediate piece 40 can be designed as an engagement surface for a tool, for example a wrench or spanner, so that the rotary movement between the release position FP and the locking position VP can be introduced via the tool onto the fastening device 2. For example, the circumferential surface U can be n-sided, in particular hexagonal.

[0075] Figure 7b This shows a design variant in which the first and second fastening sections BA1, BA2 are identical, in particular like the first fastening section BA1 of the design variant of Figures 4 and 5 Alternatively, within the scope of the invention, it is also possible that the first and second fastening sections BA1, BA2 are identically designed, such that the second fastening section BA2 of the Figures 4 and 5. In particular, by means of such a quick-fastening device, two further components or parts can be detachably arranged directly or indirectly on the machine frame 110 of the transport device 100, in particular detachably connected or fastened.

[0076] Figure 8 Figure 1 shows a schematic side view of another variant of the quick-fastening device 2, which differs from the variant of the Figures 4 to 7 does not have a first and second plant section AL1, AL2 and no receiving groove 24 extending perpendicular to the central longitudinal axis MA and is designed for the detachable arrangement of further components or parts directly or indirectly on the machine frame 110 of the transport device 100.

[0077] For this purpose, in the version of the Figure 8The respective mounting surface is formed by the corresponding first and second components themselves, each of which has at least the partially flat section 23 and a pre-drilled hole or opening 20 that deviates from a circular shape, against which the first and second locking sections VA1, VA2 mutually support each other in the locking position VP. For this purpose, both the first and second fastening sections BA1, BA2 each have at least one locking element 25, as described in the embodiment of the Figures 4 and 5 was explained in more detail.

[0078] Furthermore, the quick-fastening device 2 can also be used according to the Figure 8a through-passage in the form of an opening 28 penetrating the first and second fastening section BA1, BA1, which may have at least a partial internal hexagon in the area of ​​the pipe section 27, which forms a surface for engagement of a tool, for example an Allen key, so that the rotary movement between the release position FP and the locking position VP can be initiated via the tool onto the fastening device 2.

[0079] The invention has been described above using exemplary embodiments. It is understood that numerous modifications and adaptations are possible without departing from the underlying inventive concept. Reference symbol list
