SU33923A1 - Counter the number of cars passed - Google Patents

Description

The proposed device relates to counters of the number of cars that have passed, having a rewind from one Jalik to another tape, provided with a series of digits printed on it. According to the invention, for the purpose of intermittent movement of the tape, the latter is provided with holes equally spaced from each other so that the oscillating measles of the electromagnet can mechanically interlock with this tape, the circuit of which closes and then opens with a passing trolley.

In the drawing, FIG. Depicts schematically a 4th counter, the casing of which is shown in section; FIG. 2 is a top view of the tape and rollers.

Rollers 2 and 3 are installed in the casing 5, the first of which is equipped with a spring 4, which tends to rotate the roller in a clockwise direction. The tape 7, provided with equidistant holes from one another /, W ..., is rewound from valia 3 to roller 2. Under the belt / are located electromagnet 6, the measles 7 of which can make tilting. The anchor 7 carries rounded protrusions 8, 9 and is under the action of a spring 22, which tends to turn the measles 7, lower the protrusion 8 and lift the protrusion P. The protrusions 8 and can enter / into the JO, 70 ... tapes 7 and: nests 77 and 72, respectively, made in the casing 5.

232X

Under that shoulder of the lever 7, which carries the protrusion 9, there is one Ileo swivel lever / 5, on: the other shoulder of which rest the button J3. Outside on the casing there is a movable latch serving to hold the button 75 in the lowered position. By push button 13, there are Obi1N-open contacts J6, L, included in the circuit of electromagnet 6, and the last current source 75 supplying it. In parallel with the contacts 16, 17, the contact 19 is switched on, periodically closed by passing trolleys. In the casing 5. There is a hole-window 20 through which a number can be observed on the tape, indicating the number of cars traversed.

The operation of the counter is as follows. In the embodiment shown in FIG. I position of the electromagnet circuit. Ji closed by pin 19 by the action of a passing trolley. The tension belt 7 is spring-loaded / and BbicTyj is prevented from moving 8, entering into one of the holes 10, 10 ... of the tape and the socket 77 of the case 5. When the electromagnet 6 is opened by contact 19, the measles 7 are turned by iodine by the action of the spring 22; in this case, the protrusion 8 emerges from the opening 10 of the tape and releases the latter, and the protrusion 9 presses against the tape. The belt 7 moves towards the roller 2, rolling onto the latter 2 from the roller 5. At

Above the protrusion 9, the hole JO of the tape appears, the protrusion 9 enters this hole and into the nest / 2, thereby hardening the tape, preventing its further movement. At this moment, the next digit of the tape appears under the hole 20.

With the passage of the next car, the contact / P closes the circuit of the electromagnet 6, the latter is excited and attracts the measles 7. At this, the protrusion 9 comes out of the opening of the tape /, and the protrusion 8 presses against the tape. The tape is again moved in a directional direction and then stops again when the opening JO of the tape approaches the protrusion 8 and the protrusion enters this opening; the details of the counter will occupy the position shown in FIG. 1. In the future, work with, the chetcher will proceed as already described above. Thus, during the passage of the trolleys, the electromagnet b will be periodically excited, the measles 7 will perform rocking movements, the tape / will move intermittently from left to right. To rewind the tape J from the roller 2 onto the roller 3, press the / 5 button and lock it with the latch / - # in the lowered position. In this position, the button 73 presses down one shoulder of the pivoting lever 75 and closes in contacts 16, 17 the circuit of electromagnet 6, which is opposite 7. The latter will turn so that the protrusion 9 will come out of the hole 10 of the tape, but the protrusion 8 into the tape does not will come in, since the second lever arm 75 will and thus will hold E1kor 7 at a certain distance. electromagnet pole 6. Tape / yuddet completely free. Now it is possible, by rotating the roller 5 at the handle 27, to rewind the tape 7 from the roller 2 to it. The rewinding lasts until the figure 0 is shown in the hole 20. Press this latch 14 to retract and release the button 13. The chain

the electromagnet 6 opens and the tape is locked by a protrusion 9. The meter is ready for further work.

The author points out that as a tape of 7 ms1 it is possible to use a film, cutting off its perforated edges, piercing the holes 10.10 on it ... and numbering them properly.

Yavtor assumes that such an account is v. can be used especially in mining hoists for the purpose of accounting for trolleys issued to the top. In this case, contact 19 is placed in the shaft or at the lifting machine; in the first case, it is closed by a trolley, in the second, by the movable part of the indicator. Finally, the electromagnet 6 can also be included in the electrical signal circuit of the elevator; here, when the signal circuit closes, the counter also functions in the same way as the signal.

The subject matter of the invention.

Claims (2)

1. A counter of the number of passed trolleys with the use of a rewinding roller onto another tape with random numbers on it, characterized in that, in order to intermittently move the tape 7, it is equipped with: holes 10, 10 .., equally spaced from each other which may alternately enter the rounded protrusions 8, 9 of the oscillating cortex 7 of the electromagnet 6, when turned on: the latter is connected to the circuit by means of a 7P contact closed by a passing trolley and then switched off. 2. In the counter according to claim 1, in order to release the tape 7 from its delay by the projections 8, 9 when it is rewound to the roller 5, use the latch / 4 button 13, which serves to close the electromagnet b contacts 16 and 77 and simultaneously hold by means of a lever 75 core 7 of an electromagnet at a certain distance o | - of its poles. /, (.1, .J / /  I Y-j- (mva,: wa / / iO F 09 pg O 7OgO,; 5 Q4X33Of OlS ir / FIG. 2 F f
