Description

GERMAN

The invention relates to an electrical value input device for calculating machines, their setting rods start on value-determining attacks, which attacks under the influence of the Arithmetic values associated with electrical potentials standing electromagnets are adjusted.

The limitation of the adjustment movement of calculating machine parts during the value movement and when bringing in values from outside have so far taken place either through mechanical drives or electrically by pulse-controlled and voltage-controlled switching means such as selectors and relays. With the known A great deal of effort is required for this arrangement.

The invention is intended to create a simple circuit arrangement that controls the movement of value the adjusting members limited in the simplest possible way. The electromagnetic According to the invention, controlled stops or slides have, on the one hand, a flow valve Coils connected to a common encoder potential line, which on the other hand are connected to a control potential corresponding to a certain value. The control potential increases from coil to Coil in such a way that all coils respond magnetically with a control potential that differs from the transmitter potential.

In order to keep the electrical power low, provision is made within the scope of the invention for each slide to assign a contact located in the encoder line, which can be opened mechanically by means of its slide is. This ensures that only the first slider to respond is moved and all the following ones The slide valve can be switched off by the encoder line when a value is recorded.

According to the invention it is further provided with pure adding machines or counters that only are suitable for addition tasks to perform subtraction tasks. To that end is a Second encoder line connected to the solenoid valve coils via flow control valves. As potentials incoming values can be switched from the first to the second encoder line. Simultaneously the control potentials are switched in such a way that they decrease from coil to coil and all coils respond magnetically in reverse with the control potential below the value of the encoder potential. An addition of the complement values is then achieved, which in the calculating machine a subtraction is performed.

IJm the energy consumption even with such an arrangement To keep it low, a second contact can be assigned to each slide in the encoder line be. These contacts are then in the second encoder line.

In the drawing, two switching arrangements of the subject of the invention are shown, namely shows 1 shows the basic circuit diagram,

Fig. 2 is a circuit diagram for reduced energy consumption.

Ten solenoid valve coils 16 are connected to a transmitter line 14 via flow control valves 15. the Magnetic valve coils move a small core.

The other end of the magnet coils 16 is connected to the lines 17. Each line 17 is present a certain control potential, which increases from coil to coil.

The numerical values are transmitted by the encoder 11 as a voltage potential via the lines 12 and the Changeover switch 13 given to the encoder line 14. All coils 16, whose control potential comes from lines 17 is higher than the value potential in the transmitter line 14, are influenced magnetically. They pull their kernels and thereby limit the setting rods of the calculating machine. The effectiveness the control slide 16 is achieved by the flow control valves 15 switched on.

A second transmitter line 20 can also be switched on by means of the changeover switch 13. This second The encoder line 20 is connected to the coils 16 of the solenoid slides via flow control valves 21. The activation the second encoder line 20 is provided for a calculation with calculators that only adding can work to achieve the complement values, whereby subtractions are performed can. When the encoder line 20 is switched on, the control potentials must be switched over at the same time. those on the individual coils of the magnetic slide

16 are to be made. For this purpose, the switches 18 are provided, which give the corresponding potentials from the control potential lines 19 to the lines 17. The switching of the control potentials in the lines 17 has the effect that the control potentials are reduced from coil to coil in contrast to the arrangement described above. All coils with a control potential below the encoder potential now respond magnetically. In FIG. 2, a switching arrangement is shown in which each slide in the transmitter line 14 is assigned a contact 22 which can be opened mechanically by its control slide 16. By switching on the contacts 22 it is achieved that energy is saved and only the first responsive slide needs to be moved. All subsequent slides are switched off by the encoder line 14 by opening the contact of the first responsive slide. In the switching arrangement according to FIG. 2, a second transmitter line 20 is also provided. Further switching contacts 23 are switched on in this transmitter line 20, one contact 23 also being mechanically actuated by each control slide. When calculating with complementary values, the changeover switch 13 is placed on the line 20. Thus, only the first responsive slide is moved, and all subsequent slides are switched off by the transmitter line 20 by opening the first contact 23. In the exemplary embodiment in FIG. 1, a transmitter 11 is shown with a circular movement. In the exemplary embodiment in FIG. 2, this encoder is designed for linear movement with a grinder 24. The individual contacts of the encoders are designated from 0 to 9 and correspond to the numerical values to be set, which are given as potentials in the encoder lines. Both the control potentials and the transmitter potentials are taken from the same power source, so that a compensation of the potentials is not necessary. The potentials on the magnet coils are increased by a numerical value compared to the potentials on the encoder. In the case of a calculation with complementary values, the reverse is the case; H. the values are compared to each other by a value figure. PATENTAX PACKAGE: 1.
