Definitions
- the invention relates to a multi-range program switching mechanism with a mechanical gear driven by any motor with at least two different rotational speeds of the drive of a detachably mounted program carrier for controlling mechanical and / or electrical or electronic switching devices, in particular for radio or time measuring devices .
- one and the same program carrier is firmly connected to the time switch mechanism and assigned to the same contact system and provided with a changeover gear, by means of which its speed of rotation, for example from one rotation per week to, for example, one Revolution per day and vice versa is switchable.
- Two scales as well as exchangeable individual scales are provided for the scale-based identification of the program carrier for the respective speed.
- the invention is based on the object of eliminating the disadvantages of the known program switching mechanisms and creating a single program carrier for at least two switching program areas, in which confusion of the areas with one another or the loss of a program carrier area is excluded.
- each side or surface of a program carrier is assigned a special program area with its own scale, and each program area has its own coupling half on the program carrier, for engagement with a corresponding coupling half of the drive.
- a program carrier To change a program area, a program carrier must therefore only be turned over, brought into engagement with the drive and secured axially.
- An advantage of such a program switching mechanism is not only the absolute unmistakability of individual program areas related to a scale for the drive in question, but also in particular the insertion of such a multi - area program carrier.
- Another advantage is the ease of use and economical manufacture of such a program carrier according to the invention, which can be disc-shaped, or plate-shaped, or roller-shaped, or band-shaped, and for triggering a control signal with fixed or portable switching cams or other switching signal-triggering switching means, the latter Traps are freely programmable and are captive or detachable from the program carrier.
- the disk-shaped, in particular one-piece, program carrier 1 consisting of a plastic is on each of the two plan sides 2 and 2 a provided with a scale of 3 or 4.
- Each of the sides 2, and 2, respectively A corresponds to a Pragramm area and for each of the program areas is on the program carrier 1, a coupling half 5, or 6 is provided for engagement with corresponding drive shafts.
- the coupling halves 5 and 6 are in particular designed as so-called claw couplings, the spatial distances between the claws of one half 5 and the claws of half 6 being different, as can be clearly seen in FIG. 1.
- FIG. 3 shows in more detail, there the coupling half 5 to side 2 with the scale 3 and the coupling half 6 to side 2 ⁇ with the scale 4 of the program carrier 1, which is axially limited there on a bearing pin 8 by means of a fastening nut 7.
- the coupling half 5 of the program carrier 1 is there with a coupling half 9 of the same size or congruent, one of two drive tubes 10a and 10b, which are mounted coaxially with the bearing bolt 8, but rotating at different speeds, both of which can engage with each other via a gear stage 11, whereby the drive tube 10a can be driven directly by a pinion 12 of a central drive with any motor.
- the program carrier 1 is first removed from the bearing pin 8, turned 180 ° and put back on the bearing pin 8, the coupling halves are brought into engagement with one another. and again axially limited by the nut 7.
- FIG. 13 there designates a control shaft with a switching star 14, which of the switching cams 15, according to Fig. 1 u. 3 is applied in accordance with the switching program, for triggering control signals at corresponding devices.
- the program carrier 1 if necessary, for each program area, each with its own Drucknakkenbahn 15a u. 15b, which are independently programmable for each program area, is provided.
- the switching cam tracks 15a and. 15b can be arranged spatially one above the other - u. be integrally connected to the program carrier.
- the switching cam tracks 15a and 15b can be divided over the circumference into individual cams, which are broken out to form a switching program.
- switching tabs 28 which are shown in more detail in FIG. 4, on the program carrier 1 instead of switching cams.
- Such freely programmable switching tabs 28 can be designed to be non-removable or removable from the program carrier 1.
- the program carrier 1 is provided on the side 2 with an internal ring gear 16 and the adjacent side 2 with an external ring gear 17.
- the internal ring gear 16 is in engagement with the pinion 12 of the central drive. If the program area is now to be changed, then by loosening the axially limiting fastening nut 7, the program carrier 1 is removed from the bearing pin 8 and turned over, i.e. turned and put back on the bearing pin, the outer ring gear 17 now coming into engagement with the pinion 12. The direction of rotation remains the same due to the change of range.
- FIG. 6 shows a multi-range program switching mechanism with an annular multi-range program carrier 1, with a gear coupling between the individual program carrier sides 2 or 2a and a pinion 12 of the central drive.
- the relevant scales can be arranged in the area of pages 2 and 2a.
- Switch cams or other switch tabs can be arranged on the ring end face.
- the ring-shaped program carrier 1 is simply removed from the bearing flange 24, turned through 180 ° and plugged back onto the bearing flange and fastened axially by a position securing device (not shown in more detail).
- Other functional parts can be arranged and stored in the cavity 25 of the bearing flange, the program carrier 1 rotating around these functional parts.
- FIG. 7 shows an arrangement of a plurality of multi-area program carriers stacked one above the other according to the present invention, which, as already described in FIG. 2a are provided both with corresponding scales and with coupling halves for the respective engagement with the corresponding coupling halves on the drive side, which are arranged there on drive tubes 26 which are mounted coaxially to one another.
- the drive tubes 26 have different rotational speeds from one another.
- the devices according to the invention described above for creating a multi-range program switching mechanism can also be transferred to tape-shaped program carriers 1.
- 8 shows, for example, a band-shaped program carrier 1, in the region of the outer edges with a perforation 27 for the engagement of a switching or other drive mechanism, with a pinion 12. Instead of the perforation 27, spur toothing can of course also occur.
- Scales 3 and 4 can be provided on pages 2 and 2a respectively.
- Switch cams 15 or other signal-triggering elements or markings can also be provided.
- Program to range shift of the program carrier 1 is lifted out of the drive and turned through 180 0 and engaged with the second drive gear 12a, which has a different round-trip time as the pinion gear 12 in engagement.
- a further expedient embodiment of a program carrier 1 can be in a cube-shaped form, in which all six sides of the cube have an area with their own scale, corresponding control means in the form of switching cams or switching tabs or other control means and corresponding coupling halves for the optional engagement with corresponding coupling halves Central drive can be provided.
