Decadal electric pulse counter

The present invention relates to a decadic Llektroiinpuls counter, especially to determine the Rotational speeds of Ila & chinen and work motions of various Ivechani & men, if necessary also for length measurement and especially to control different work performances with a planned number of repetitive Operations, with this counter being able to determine another program as well as a repetition of the cycle after nullification and forms a component for the grouping together.

Known electric pulse counters, especially for the purpose of automation, unite a great number of Elements that enable their activity, which

particular is characterized by the registration of impulses and in the definite, predetermined in advance Transfer a certain momentum to the next level or to carry out a certain work serve the associated device, in the circle of which the mentioned counter is switched on.

For the activity of an electric ο impulse counter it is It is particularly important that any attitude is easily possible at that moment in which a certain recorded impulse transferred to the next level of higher! tang or immediately to the recording a certain work performance of the associated device is used, in whose circle the counter is switched on is. This is also related to the so-called area code, which always takes place before a specific one is recorded Function of the counter is set. The mentioned area code is only available with a certain basic position of the Counter adjustable, which is achieved by a mechanical or by electric impulses zeroing.

A disadvantage of previously known decadic electric pulse counters consists in that the meter is composed of a large number of ropes and in complexity of the internal electrical circuits. These are on many counters, especially for the purpose of achieving a Smallest possible size of the counter and to prevent defects or to make it easier to contact the printed Connections carried out and further through the use of various semiconductor rectifiers or switching elements

with its circular recess in a recess 14 a have 15 of the counting member 1, whereby this counting member 1 with the counting member 2 inevitably engages is brought. The counter element 1 is an organ in the form of a key 16 for the purpose of disengaging the counter element 1 assigned from engagement with the second counting member 2, this key 16 being rotatable in two holders 13,17 and is slidably mounted and these holders are attached to the frame 4. On the shaft of the key 16 is a squat 18, which with a release means in the form of a thumb 19 for the purpose Cooperation with a projection 20 provided on the hub 15 of the counting member 1 is provided as soon as As will be further described, the key 16 is rotated.

The one designed as a key 16 and for disengaging the counting member 1 from engagement with the counting member 2 Serving organ is further assigned a spiral spring 21, which comprises the shaft of the key 16 and with one end is suspended in the holder 13 and the other end in the cam disk 18, the aforementioned Coil spring 21 on this cam 18 causes a compressive and torsional moment.

A free end 22 of the key 16 is for loading Made contact with the armature 7 of the electromagnet 8, while the other bent end 23 of the same Key 16, which protrudes from the end wall 24 of the counter i), adapted for manual operation

is. The key 16 is as long as it is in the in all the figures is in the position shown, held in its longitudinal direction by the flat spring 12, which is supported with its recess 12a against the lower part of the squat 18 (FIG. 4).

suffering counting members 1,2 are on their outer circumference with Projections 25,26 are provided, which means for the actuation of spring bundles 27,28 formed essentially Contact organs serve. These spring bundles 27, 28 are fastened with one end on the electromagnet 8 equipped at its other free end with associated contacts 29, 29a, JO.

The described counter works as follows:

The current pulses supplied to the electromagnet 8 call a pivoting of the armature 7 about the axis 9 outwards. This pivoting is activated by the pawl 6 on the Transferring ratchet 5 of the counter 2, with the counting member 2 is rotated by an angle of 36 ° with each movement of the pawl.

Coinciding with the counting member 2, the counting member 1 also rotates because these two members are connected to one another are bound by driving elements 10, 11.

However, as soon as the projection 26 of the counting member 2 comes into contact with the associated spring bundle 28,

009824/1312 " ⁷ "

bind the corresponding contacts 30, whereby the electrical circuit is closed and one is not The device shown is set into [activity which, for example, switches off an associated machine or switches on another organ of the machine to carry out another work.

When the current pulse supplied to the electromagnet 8 closes the mentioned contacts 30, is determined by the so-called preselection, which only takes place after the counter has been moved to a certain basic position can be performed in which the counter is zeroed.

The elimination of the voter is through a not shown Source of zeroing pulses carried out which It is immediately started as soon as a certain electrical circuit is closed by means of the contacts 30 and thus fulfills a certain puncture of the counter became. The Kullung impulses are closed over the Contacts 29,29a of the Pederbund 27 to the electromagnet 8 supplied, the armature 7 through it is attracted normally, so that the counter 2 rotates.

Simultaneously with the counter 2, the counter rotates 1, because uieses link is tied to counting link 2 up to now. The whole system of the counting elements 1,2 is twisted as long as the projection 25 of the counting member

- 8 009824/1312

1 does not run against the corresponding spring bundle 27 and thus the contacts 29, 29a are separated from one another.

By separating the contacts 29 »29a from one another, the electrical circuit of the electromagnet 8 is interrupted and thus the further operation of the meter is suspended. At the moment when the counter indicates that there is an action the means mentioned comes to a standstill the counter is zeroed out, whereby a certain basic position of the counter is determined, from the later one Setting the preselection, i.e. Number of pulses, which is to be checked by the counter, is assumed.

The zeroed position of the counter can be advantageous are optically tracked on de.n associated counter 1, its associated brand or number, which of the above corresponds to the listed position of the counter, in the associated sight glass 31 on the face 24 of the counter appears.

In this position of the counter or of the counter element 1, the preselection can be carried out with the key 16

If the key 16 is turned in the direction of the arrow S (Fi ^. 2), the thumb 19 approaches the cam disk 18 provided on the Iiabe 15 of the counter 1

- 9 -009824/1312

Projection 20 (]? Ig.4), which only in this position . "of the counting member, 1 by the mentioned thumb 19 er7 can be grasped. By further turning the key 16, the thumb 19 moves according to cooperation the projection 20, the counting member 1 out of engagement with the counting member 2. At the same time, the Flat spring 12 swung out, which when the key 16 is later compressed, the counting member 1 in disengaged Position obtained, although the thumb 19 of the cam 18 is then out of reach of the Projection 20 is located. The flat spring 12 remains when the key 16 is pressed together by the ■ Cam 18 of the key 16 swiveled out. The cam 18 is also on the contact side with one? Locking surface or recess 52 provided, which prevents the key 16 from rotating freely when it is pressed together.

With axial pressure on the key 16 in the opposite direction the spiral spring 21 comes the free end 22 of the key 16 on the armature 7 of the electromagnet 8 to rest. By subsequent interrupted cooperation of the key 16, the mechanical impulses are through the ratchet 6 and the ratchet 5 are transferred to the counter 2. This increases the number of Impulse determines which should be checked by the counter, i.e. at which impulse the contacts are 30 of the spring bundle 28 should close so that it is desired activity of another device, not shown, comes.

The number of controlled pulses is using

determined by numbers or other characters with which the counter 2 is provided and which when carried out the preselection can be followed again in the sight glass 33 on the face 24 of the counter.

There. the number of pulses controlled by a counter and limited by the number of each Positions are given which the counter 2 can assume, can be given a desired larger number of pulses switch several counters one after the other, whereby their output pulses, as will be explained further is transferred to each other and total.

If the preselection is set so that the counter receives e.g. ten pulses, which e.g. 3. the capacity of the counter 2 represents, then runs at the recorded tenth pulse, i.e. as soon as both counting elements 1.2 to Turn around an angle of 360 °, the projection 25 of the counting member 1 on the movable part of the spring bundle 27, the two contacts 29 being connected to one another. This becomes the tenth impulse inasmuch as it is a device (not shown) is not used directly to perform any puncture Transfer of the mentioned contacts 29 to the subsequent meter of the same type. This counter then registers and counts the impulses of higher rank, with this also following counter and any a preselection can be carried out for further counters.
