Definitions
- the invention relates to a closing device for a filler neck arranged on a container, in particular for at least one container arranged on a rail or road vehicle and which can be fed to a loading station for loading powdery or granular bulk goods, the individual container having at least one via an inlet opening with the container interior has connected filler which can be closed on the outside by a cover.
- the containers each provided with at least one filler neck for loading them with one or more silo containers provided loading station can be fed.
- a cover arranged on the inlet connector weather protective
- a loading head connected to the silo container is inserted into the filler neck or into the interior of the container.
- the cover is fastened again to the filler neck for transport, for example by means of a screw connection or the like.
- the container which is provided at one end with a nozzle for pressurization and at the other opposite end with an outlet nozzle, is pressurized with compressed air for emptying when the outlet nozzle is open when the outlet nozzle is open.
- the problem with the known transport containers is that the cover and the means for fastening the same are exposed to the external conditions (summer and winter operation) and become relatively heavily soiled when loaded with dust-like material such as cement or the like.
- the removal of the cover arranged on the filler neck can only be carried out after taking into account appropriate safety regulations after relatively time-consuming and costly cleaning of the cover and fasteners.
- the individual fasteners (screw connections) and the cover closing the filler neck are no longer functional after a relatively short period of operation and have to be replaced with a relatively large amount of time and money.
- the locking device is characterized by a closure element mounted in the interior of the container on a support arm, which, depending on a pivoting movement of the support arm oriented approximately in the horizontal plane, can be engaged or disengaged with an annular sealing surface assigned to the inlet opening, the sealing surface either on a coaxially in arranged the filler neck and projecting into the container interior end of a hollow cylindrical insert body or on the end of the filler neck projecting into the container interior.

- FIG. 9A the approximately hood-shaped cover 63 is shown in section, and the support arm 64 arranged thereon with one end and a holder 72 for an annular seal 73 arranged on the inside 74 of the cover 63 can be seen around the vertical axis Z in the direction of the arrow Z 'oriented rotary movement of the screw piece 58 supported on the housing 70, the cover 63 is moved in accordance with the direction of the arrow P shown in FIG. 9A and is pressed with the seal 73 sealingly against the filler neck 5.3. In the closed position of the cover 63, the compression spring 68 arranged in the housing 70 is largely compressed (FIG. 9A).
- the individual elements are moved as a result of the restoring force of the compression spring 68 in accordance with the direction of the arrow P 1 shown in FIG 5.3
- the compression spring 68 is designed and dimensioned in such a way that it ensures the stroke movement oriented in the direction of arrow P 1.
- a correspondingly designed disk spring assembly (not shown) can be arranged on the axle body 55.1. In the position shown in FIG.
- the axle body 55.1 provided with the polygon 56.1 can be rotated about the vertical axis Z in the direction of the arrow Z "by means not shown.
- the rotary movement ensures that the cover 63, which is essentially operatively connected to the axle body 55.1 is pivoted relative to the filler neck 5.3
- the closure element 40 mounted on the support arm 50 can simultaneously be pivoted in a horizontal plane relative to the insert body 35 projecting into the container interior 7.
- FIGS. 10A to 10F A variant for the inevitable actuation of the cover 6.3 arranged on the filler neck 5.3 is described below with reference to FIGS. 10A to 10F, the opening 6.3 and the closing in FIG. 10A to 10D being shown in FIGS. 10A to 10D.
- Fig. 10A shows a section of the schematically illustrated loading station 10 with brackets 11 and 11 arranged at a distance from one another therefor for two guide rails arranged in the entry direction and designated by 13 and 13.1. Furthermore, one can see the schematically represented container 2.2 with the filler neck 5.3 and the cover 6.3 arranged thereon in the closed position. On the filler neck 5.3 there is a schematically shown pivot bearing 85 which is provided with a lever arm 86. The pivot bearing 85 further comprises a support arm 89 fastened to the cover 6.3 and operatively connected to it. A plate-shaped slide 87 is arranged on the approximately hood-shaped cover 6.3 and fastened by means not shown. Furthermore, a handle 88 can be arranged and fastened on the side of the cover 6.3 opposite the pivot bearing 85.
- FIGS. 10B and IOC Starting from the cover 6.3 shown in FIG. 10A in the closed state, this is shown in FIGS. 10B and IOC according to the direction of arrow S in an arbitrarily selected intermediate position and in FIG. 10OD in the maximum open end position.
- the cover 6.3 is pivoted by means of the guide rail 13 pressing against the lever arm 86 about the axis of rotation of the pivot bearing 85, not shown, relative to the filler neck 5.3 up to the end position according to FIG. 10 in which the container 2.2 is loaded.
- the rail car After loading, the rail car is transported further and, as shown in FIGS. 10D and 10E, the cover 6.3 is pivoted in the direction of the arrow S 1 as a result of the guide rail 13 pressing against the slide 87, and the cover 6.3 finally engages with the filler neck 5.3 brought (Fig.lOF).
- the covers 63 (FIGS. 9A, 9B) or the covers 6.3 (FIGS. 10A to 10E) described above and designed as weather protection and arranged on the railroad car or the like are made, for example, of light metal (cast aluminum) or of a suitable plastic.
- the individual cover 6.3 or 63 can be fastened to the filler neck in a form-fitting or non-positive manner by means not shown in any more detail.
- the actuating or handling module 80 for example arranged at the loading station 10 and shown schematically in FIG. 8, for actuating the pivoting direction 65 (Fig.5) or the pivoting device 65.1 (Fig.9A and 9B) and the individual brackets 11 and 11.1 arranged on the loading station 10 with the attached and oriented in the transport direction guide rails 13 and 13.1 according to Fig.LOA to 10F are not Subject of the present invention and therefore not described in detail.
