DETAILED DESCRIPTION

(12) FIG. 1 shows a road finisher 1 for paving a road surface B. The road finisher 1 is equipped with a hopper 2 for receiving a paving material E. The paving material E is transported from the hopper 2 by means of a longitudinal conveyor (not shown) to the rear against a paving direction R to a paving screed 3 which is movably mounted on the road finisher 1. The paving material E is spread out in front of the paving screed 3 and compacted by the paving screed 3 to produce the new road surface B.

(13) The paving screed 3 is equipped with a side shining device 4 with an external control station 5 attached thereon. An operating panel 6 as a functional input unit for an operator is attached to the external control station 5. The operating panel 6 can be used to set a large number of operating parameters for the paving screed 3 and/or the road finisher 1 and to call up operating parameters currently set for operation. FIG. 1 shows schematically an operating parameter P, for example, concerning an adjustable output of a screed heating system installed on the paving screed 3.

(14) FIG. 1 also shows an external control station 5′ mounted on the other side of the paving screed 3 with an additional operating panel 6′ attached to it, which can be attached and removed in the same way as the operating panel 5.

(15) FIG. 2 shows in isolated view the external control station 5 of the paving screed 3. The operating panel 6 mounted on the external control station 5 according to FIG. 2 comprises at its top side 7 a plurality of input switches 8 for the operator. In addition, the operating panel 6 has a display 9 in an upper section on its top side 7 for showing currently set operating parameters P, which can, however, optionally be designed as touch display for setting various operating parameters P. The display 9 can also indicate that the operating panel 6 is correctly attached to the external control station 5.

(16) FIG. 2 shows that the operating panel 6 has lateral engagement recesses 10 for holding the operating panel 6 on both sides. In addition, FIG. 2 shows that a handle 11 protrudes into the right-hand engagement recess 10, protruding over a lateral edge 12 of the operating panel 6, visible to the operator, to indicate to the operator by mechanical means that the operating panel 6 is correctly attached.

(17) FIG. 3 shows a support 13 of the external control station 5 without the operating panel 6 mounted on it. The support 13 is designed in the form of a mounting saddle 14 on which the operating panel 6 can be slid along a mounting direction M. In addition, an emergency stop switch 15 for stopping the paving operation is provided on the support 13, separated from the mounting saddle 14. In addition, FIG. 3 shows that the support 13 is equipped with a signal unit 16, which can be used in particular to indicate the position of the external control station 5, for example to avoid collisions with the external control station 5 during construction work.

(18) In FIG. 3 the support 13 is mounted on a mounting tube 17 in a height-adjustable manner. FIG. 3 also shows a base plate 18, which is formed on the mounting saddle 14 of the support 13. When resting on the base plate 18, the operating panel 6 can be placed in a stable position if it is attached to the support 13 of the external control station 5.

(19) FIG. 4 shows the external control station 5 from a view from below. The operating panel 6 has an underside 19, by which the operating panel 6 is attached to the support 13. The underside 19 of the operating panel 6 is provided with a ground spotlight 20. The ground spotlight 20 can be used to illuminate the subgrade directly below the operating panel 6, in particular a terminal edge of the newly produced road surface B.

(20) FIG. 4 also shows a mounting part 21, which attaches the support 13 to the mounting pipe 17. The mounting part 21 is designed to support the support 13 in a height-adjustable manner and to rotate it around the longitudinal axis of the mounting tube 17.

(21) FIG. 5 shows a part of the support 13 of the external control station 5. FIG. 5 shows a first connector part 22 on the support 13 with an integrated first electrical contact part 23. The first connector part 22 has two parallel guide rails 24. On the support 13, the two guide rails 24 form a linear guide 25. The linear guide 25 comprises a lighting unit 35 for illuminating the respective guide rails 24.

(22) In addition, FIG. 5 shows a protective flap 26, which is assigned to the first electrical contact part 23. When the operating panel 6 is not mounted on the support 13, the first electrical contact part 23 can be covered by the protective flap 26 to prevent the first electrical contact part 23 from being exposed to the weather and from becoming soiled. In addition, in FIG. 5, the first electrical contact part 23 is assigned a seal 36 running around it.

(23) In FIG. 5, the first plug connector part 22 provided on the support 13 is designed as part of a plug connection device 27, which is used when attaching and removing the operating panel 6 to the support 13. The plug connection device 27 is formed from the first plug connector part 22 together with the second plug connector part 28, now described in conjunction with FIG. 6, to allow the operating panel 6 to be easily attached to the support 13 of the external control station 5.

(24) The second pug connector part 28 of the plug connection device 27, shown in FIG. 6, has a second electrical contact part 29 integrally formed thereon and insertable into the first electrical contact part 23, which is dockable to the first electrical contact part 23 of the first connector part 22 of FIG. 5 to establish an electrical coupling on contact.

(25) As shown in FIG. 6, the second plug connector part 28 is formed on the underside 19 of the operating panel 6. The plug connection device 27 has two parallel mounting rails 30 on the second plug connector part 28, which together with the guide rails 24 shown in FIG. 5 form the linear guide 25. Also shown on the underside 19 of the operating panel 6 are two laterally sliding handles 11, which can be manually operated by the operator to attach and detach the operating panel 6 to the support 13. The two handles 11 each comprise a locking projection 31, which allows the operating panel 6 to be secured to the mounting 13, in particular to the first plug connector part 22 formed on it, and to be electrically coupled, in particular when preloaded under pressure.

(26) FIG. 7 shows a schematic rear view of an external control station 5 of the paving screed 3 with two separately mounted operating panels 6a, 6b. A separate plug connection device 27a, 27b is provided on the support 13 for each of the operating panels 6a, 6b to detachably attach the respective operating panels 6a, 6b to the external control station 5.

(27) FIG. 7 also shows that the two operating panels 6a, 6b are arranged one above the other in a common schematically indicated mounting plane 32 on support 13. The two operating panels 6a, 6b can be attached to the support 13 in opposite mounting directions M1, M2 and can be removed in opposite directions.

(28) FIG. 8 shows a schematic perspective view of an external control station 5 with two operating panels 6a, 6b mounted one above the other on the support 13 along the mounting plane 32, which are arranged as separate control modules on support the 13. An operator F is positioned behind the external control station 5. The respective operating panels 6a, 6b can be removed separately from the support 13 by the operator F as input units in order to be used as mobile input units in the area of the road finisher 1, especially in the area of the paving screed 3.

(29) FIG. 9 shows a support 13 for mounting two separately designed operating panels 6a, 6b. On the base plate 18 of the support 13, the first plug connector parts 22a, 22b are formed one above the other for attaching the respective operating panels 6a, 6b. FIG. 9 also shows that the base plate 18 is attached to an upper part 34 of the support 13 by means of a swivel joint 33. The swivel joint 33 allows the base plate 18 to be adjusted to a desired inclined position to align the operating panels 6a, 6b attached to the support 13.

(30) FIG. 10 shows the free support 13 shown in FIG. 9 with an operating panel 6a attached to the upper first plug connector part 22a.

(31) The features described in connection with the plug connection device can be used both on an external control station for the attachment of one or more separate operating panels. Regardless of whether the paving screed is equipped with a single or multiple operating panels, the operating panels can be ergonomically connected and disconnected both mechanically and electrically from the external control station in a single coupling procedure.
