DETAILED DESCRIPTION

[0035] The present disclosure relates to a station for a cable transportation system, a cable transportation system equipped with such a station, and the method for operating the system as regards the management of the movement of the transporting units inside the station.

[0036] FIG. 1 shows a schematic, side elevation view of a portion of a cable system 2 provided with a station 1 according to the present disclosure. In particular, FIG. 1 shows a plurality of transporting units 3, in succession one after the other, which are supported and moved outside the station 1 by a carrying/hauling cable 4. As already evident from the schematic view in FIG. 1, inside the station 1 of the present disclosure the transporting units 3 are alternately diverted along two different paths such that at least two transporting units are at at least one embarking and disembarking platform. According to the example in FIG. 1, the station has three platforms 15, 16 and 17, respectively, both between the two transporting units 3 and outside the latter. The reference numeral 14 in FIG. 1 schematizes a control unit configured to control the movement of the transporting units 3 inside the station 1. However, this control unit 14 may also be used to control the entire system, therefore without providing one control unit for each station.

[0037] FIG. 2 shows an enlarged view of the detail indicated as II in FIG. 1. In particular, FIG. 2 shows how the transporting units are guided inside the station 1 where they are no longer coupled to the cable 4.

[0038] According to the example of FIG. 2, the station 1 comprises a guiding device 7 in the form of a pair of rails 21, 22 which support respective roller portions of a suspension arm 23 connected to the roof 24 of the transporting unit 3. The advancing, acceleration and deceleration of the transporting units along these tracks 21, 22 are imposed by a plurality of motorized wheels (not shown and, in certain embodiments, made of rubber), which act, in certain embodiments, against a corresponding knurled portion 26 at the top of the suspension arm 23. At the bottom, the represented transporting unit 3 is contained by side walls 20 optionally integrated into the disembarkation and embarkation platforms 17.

[0039] FIGS. 3 to 6 show schematic views of alternative embodiments of stations according to the present disclosure. In particular, these embodiments differ in the arrangement of the embarking and disembarking platforms 15, 16, 17 with respect to the guiding device 7. However, all these embodiments, which show repeatable modules even within the same station, enable the movement of the transporting units 3 in the station 1 to be controlled as provided in the present disclosure. In this respect, before describing in detail the differences in the embodiments of FIGS. 3 to 6, attention will be given to the common characteristics that contribute to the implementation of the disclosure.

[0040] In particular, in all the embodiments of FIGS. 3 to 6 the guiding device 7 comprises a plurality of guides arranged in succession (and shown in plan view) between the inlet 5 and the outlet 6 of the station. At such inlet 5 and outlet 6 points of the station 1, the reference numerals 25 and 27 schematize a device for respectively uncoupling and coupling the cable 4. The arrows I and O indicate the forward direction of the transporting units 3 entering and exiting the station 1.

[0041] In particular, the guiding device 7 comprises an inlet guide 8 extending from the inlet 5 to a diverging point 9, two intermediate guides 10, 11 extending along different paths between the diverging point 9 and a converging point 12, and an outlet guide 13 extending from the converging point 12 to the outlet 6 of the station 1. Selector devices are provided at the diverging 9 and converging 12 points, which are configured so as to ensure a secure passage of the transporting units 3 at such switches. In the examples of FIGS. 3 to 6, the station 1 is configured to be an upstream station or a downstream station, but for the purposes of the present disclosure the station 1 may also be an intermediate station.

[0042] In view of the presence of two intermediate guides 10 and 11, the control unit 14 feeds in an alternating, cyclic manner a transporting unit 3 along the first intermediate guide 10 and the subsequent transporting unit 3 along the first intermediate guide 11 by controlling the operation of the selector 9. According to the examples shown, the control unit 14 activates the selector 9 when a group or train of units 3, for instance four as shown, is reached, not upon the passage of a single transporting unit 3. According to the disclosure, the control unit 14 also commands a temporary stop of the transporting units 3 at corresponding stopping points along the intermediate guides 10, 11 configured to enable the embarking and disembarking while the transporting units 3 are stopped. According to this example (i.e., with groups of four selectively diverted units 3), the control of the station can be schematized as follows.

[0043] Initially, all the stopping points provided along both the intermediate guides 10 and 11 are occupied with the respective transport units stationary to enable embarking and disembarking. In this condition, a transporting unit enters the station while a first group of transporting units 3 is set in motion along the first intermediate guide 10. The first unit of this first group exiting the station occupies the gap left along the cable 4 by the vehicle entering the station 1. This entering unit is diverted towards the first intermediate guide 10, which is being emptied, until it reaches the stopping position downstream of the guide. Similarly, the next unit entering the station 1 will be diverted to the first intermediate guide 10 until it reaches the free stopping position downstream of the guide. As indicated above, the “gaps” left along the cable 4 by the units entering the station are filled by the units exiting the same.

[0044] This procedure continues until the complete filling of the stopping positions provided along the first intermediate guide 10. At this point, the next entering transporting unit is no longer diverted towards the first intermediate guide 10, but rather towards the second one 11 where the present train of units is operated so that it leaves the station 1. Similarly as described above, the second intermediate guide 11 is also gradually emptied and filled again along the stopping positions. In this condition, the starting point is reached again and the cycle can be repeated.

[0045] As previously mentioned, the operation of the station as described above is applicable to all the embodiments shown in FIGS. 3 to 6, which differ from each other in the relative positioning of the platforms with respect to the stopping positions of the units 3 along the intermediate guides 10 11.

[0046] According to the example in FIG. 3, the station 1 comprises a common inner embarking and disembarking platform 15 arranged in the inner zone between the first 10 and the second 11 intermediate guide. According to this example, therefore, the platform 15 serves as an embarkation and disembarkation platform for all the transporting units 3 passing through the station.

[0047] According to the example in FIG. 4, the station 1 comprises an outer embarkation and disembarkation platform 16, 17. According to this example, therefore, the platform 16 serves as an embarkation and disembarkation platform for all the transporting units 3 fed along the second intermediate guide 11, whereas the platform 17 serves as an embarkation and disembarkation platform for all the transporting units 3 fed along the first intermediate guide 10.

[0048] According to the example in FIG. 5, the station 1 comprises an inner embarking and disembarking platform 15 housed in the inner zone between the first 10 and the second 11 intermediate guide, and an outer embarking and disembarking platform 16, 17 at an outer zone of one of the intermediate guides 10, 11. The example shows the outer platform 16 coupled to the second intermediate guide 11, but alternatively the platform 17 coupled to the first intermediate guide 10 may be present.

[0049] According to the example in FIG. 6, the station 1 comprises an outer embarking (or disembarking) platform 16, 17 at each outer zone of the intermediate guides 10, 11, and an inner embarking (or disembarking) platform 15 at the inner zone between the first 10 and the second 11 intermediate guide.

[0050] In FIGS. 3 to 6, the platforms 15, 16, 17 comprise a plurality of platform doors 18 at the stopping points where the units 3 stop along the intermediate guides 10, 11. FIG. 5 schematically shows a time indication device 19 configured to indicate the waiting time at each stopping point along the intermediate guides 10, 11. These time indication devices 19 may of course also be present in the remaining embodiments of FIGS. 3, 4 and 6 as well as in other embodiments of the disclosure described herein but not shown in the Figures.

[0051] Lastly, it is clear that modifications and variations may be made to the disclosure described herein without departing from the scope of the appended claims. As such, the present disclosure also covers embodiments not described in the detailed description and equivalent embodiments that fall within scope of the appended claims. Accordingly, various changes and modifications to the presently disclosed embodiments will be apparent to those skilled in the art.
