- a data carrier 13 eg a CD-ROM 13
- control device 11 operates the ski storage according to an operating method, which is described below in connection with
- the control device 11 accepts a predetermined tension Z * in a step S1.
- a predetermined tension Z * For example, an operator, not shown in FIG. 1, of the control device 11 can specify the desired tension Z *.
- the Sollzug Z * may alternatively be fixed by the control program 12 fixed.
- the desired train Z * is determined by external circumstances (for example, the operating state of a system arranged downstream of the ski storage). In the context of the present invention, it does not matter which way the desired tension Z * is given.
- control device 11 determines a
- control device 11 determines the Soll Stahl ⁇ change ⁇ F * based on a time clock with which it works, in connection with the inlet velocity vi and the out ⁇ running speed v2.
- control device 11 receives from the traction measuring devices 9, 10 the trains Z1, Z2 detected by the traction measuring devices 9, 10.
- a step S4 the control device 11 determines a desired lifting state change ⁇ h * for the traverses 7. It determines the desired lifting state change ⁇ h * as a function of the desired filling degree change ⁇ F *, the reference train Z * and at least one of the two trains Z1, Z2.
- the nominal lifting state change? H * may in particular correspond ⁇ setpoint with a torque or speed. Step S4 will be explained later in connection with FIG. 3.
- a step S5 the control device 11 determines a torque setpoint value m * or a speed setpoint value n * for each driven lower roller 6. It determines the setpoint values m *, n * as a function of the position of the respective driven lower roller 6 in the ski storage, the entry speed vi, the exit speed v2, the desired lift state ⁇ change ⁇ h * and the two trains Zl, Z2. Step S5 will be explained in more detail in conjunction with FIG.
- control device 11 outputs the Sollhe ⁇ beSullivans Sung ⁇ h * to the trusses 7 from. Furthermore, it outputs the setpoint values m *, n * to the driven rollers 6 as part of step S6.
- the setpoint values m *, n * correspond to control signals in the sense of the present invention.

- the controller 11 checks in a step S15 whether the effective train Z is smaller than the target train Z *. If this is the case, the controller 11 increases in one step S16 the desired lifting state change ⁇ h * by a correction value, which is dependent on the difference of the effective train Z and the train Z *.
- the desired lifting state change ⁇ h * is essentially determined by the desired filling degree change ⁇ F *. It depends - albeit only to a small extent - but also on the deviation of the effective train Z from the Sollzug Z *.
- step S5 menting the step S5 as a single step to imple ⁇ . According to FIG. 4, however, the following procedure is preferred:
- step S21 the controller 11 determines the speed command values n * for the driven rollers 6 as a function of the running speed vi, the running speed v2 and the target lifting state change ⁇ h *.
- control device 11 determines on the basis of the output-side train Z2 and the input-side train Zl a train difference ⁇ z.

- the desired speed values n * are essentially determined by the speeds vi, v2 and the so-lift state change ⁇ h *. However, they also depend on trains Z1 and Z2, albeit only to a small extent. In particular, they depend on whether the train ⁇ difference Az is greater or less than the Sollzugdifferenz Az *. In both cases, the speed setpoint values n * of the driven rollers 6 are corrected in such a way that the tension difference ⁇ z is guided in the direction of the desired tension difference ⁇ z *.

- 6 non-driven rollers 4, 5 are present in addition to the driven rollers.
- the driven rollers are distributed on ⁇ 6 in the general case any memory between input 2 and output memory.
- the number of driven rollers 6 in principle arbitrary. In general, the number of driven rollers 6 is greater than two. It is therefore at least three. According to FIG 1 even four driven rollers 6 are present. According to FIG. 1, furthermore, between two respective driven rollers 6, a large number of non-driven rollers 4, 5 are arranged. The latter statement applies preferably regardless of whether, in addition to the upper rollers 4 and the non-driven lower rollers 5, the guide rollers 8 are counted as non-driven rollers with ⁇ .
- the Schiingen amid is always operated uniformly.
- the ski storage may have only a single traverse 7.
- a uniform operation is possible.
- all trusses 7 must always be controlled identically.
- Each traverse 7 defines a memory section 14, wherein the memory sections 14 follow each other sequentially.
- the control device 11 it is possible to operate the individual memory sections 14 independently of each other. This will be explained in more detail below in conjunction with FIG.
- FIG 5 has the same basic structure as FIG 2. After ⁇ Following is therefore discussed in more detail only the differences from FIG. 2
- step S2 is replaced by a step S31.
- step S31 the controller 11 determines for each memory section 14 its own desired filling degree change ⁇ Fi * (i stands as an index for the respective memory section 14).
- the determination of the desired filling degree changes ⁇ Fi * is known per se.
- individual Speicherab- the sections 14 can be deactivated so that they are operated with a kon ⁇ constants degree of filling of 50%.
- step S4 has been replaced by a step S32.
- step S32 the controller 11 individually determines, for each memory section 14, a target lift state change ⁇ hi *.
- the index i is also here for the respective memory section 14.
- the respective desired lifting state change ⁇ hi * is output individually.
- Each storage section 14 is thus operated such that a Ist Stahlllgrad the respective Speicherab ⁇ section 14 is approximated to the corresponding Soll Stahl.
- step S5 is retained in the embodiment of FIG. 5.
- the control device 11 also determines a corresponding torque or speed setpoint value m *, n * for each driven roller 6 as a function of the input-side train Z 1 and the output-side train Z 2 and feeds it to the respective drive ⁇ ne role 6 from.
- the buffered in the ski storage band 1 is thus acted upon by each driven roller 6 according to the respective desired value m *, n *.
- This statement also applies, although the driven rollers 6 are distributed over the memory sections 14 and the memory sections 14 are given different desired lifting state changes ⁇ hi *.
- step S32 in determining the desired speed values n * for each driven roller 6, the desired lift ⁇ state change ⁇ hi * of the memory section 14 is taken into account, in which the respective driven roller 6 angeord ⁇ net.
