Photoelectric counting system

The invention relates to a radiation transmitter and receivers working and for continuous counting from Paoketüoken or the like. certain Lichtachranke, the Passage of the packing pieces or other shadow bodies responds and actuates a counter.

The invention "consists essentially in that in the Vor-Bchubrichtung the goods to be counted on one side of the conveying path a two light beam transmitters connected in parallel and on the opposite side two associated beam receivers connected in series are arranged so that the beams forming the light barrier cross one another.

Expediently, this light barrier is equipped with an electric motor-driven counter, to which the possibly amplified Current pulses are fed. The counter consists advantageously of an adding machine, which can be built on or installation of an electromagnetic control device coupled with the addition key, for example is. A time relay can be provided that does not respond to short-term current pulses.

The AddiermpiBchine can be provided with a locking device be that, if necessary, stops the keys that are not required for the counting process, but when released the Usual use as an office robot. Advantage-

In this way special becomes a falsehood '. Multiple response of the 'counting valve' avoided ₉ if, for example, the packaged goods and wrapping remain a grinding gap or if it is provided with an appendage, a barrier that only works with a light beam would, under certain circumstances, three times "ie" when the front part of the envelope passed through, then be home the packaged goods and Sohließlioh "address the passage of the back cover partsB and thereby show a false Brgelmi'S, Eadurcii that the beam send he and the recipient are arranged separately from each other" with the torso of the conveyor ₅ we achieved that packages with a reflective outer surface (sheet metal "container or the like) in also eimvandfroier VJeise v; eröen, since unwanted and possibly "the recipient" influencing feelings

Pig »2 a rare view of the control device provided on an adding machine«

1 is a conveying belt on which aB Baefcstücke 2 f 3? Χ means of a light barrier are supplied. On a base plate 5, two light beam transmitters 4 »5 are arranged one behind the other on one long side of the band 1 in the direction of interference, and opposite these on the other side of the band 1 are two beam receivers 6, 7, Ben transmitters 4» 5 and the receivers 6.7 the current drawn from the iieta 8 is supplied via a transformer 9 known per se. Me two transmitters 4 # 5 are parallel, while the receivers 6,7 are connected in series. According to the innovation, the arrangement is such that the light beams 14.15, which are emitted by the headlights 10, 11 of the transmitters 4 and 5 and acting on the eyes 12, 15 of the receivers 6, 7, cross one another. Hi © 3? Du3? Oli. a double or multiple interruption of the light beam is avoided with certainty when a package passes through. A timing relay can be used with the receivers to achieve increased accuracy

be connected, the interruption of the Itur side Power rays not responding? if e.g. the Psckstüek the conveyor belt should be back and forth due to a shock or a sudden standstill.

Hit the Strahlempfäagema 12,15, a counter 20 is connected via a line 18 * to which the strobe pulses are initiated. 7The current impulses, which may be appropriately amplified, lead to a magnetic coil 22 housed in an attachment 21, the armature 23 of which is drawn in in the direction of the arrow y * whose vertical Atta is provided with a slot 26 iTinkelhebels 24 »25. Kit 25 in the slot 2β one rod engages at 27 befindlicher Bolsen 28 a"She's rod 27 with "telß Schlitsfiüirun§i;.. j29 tinfi engaging screws 30 therein rectilinearly you wearing a to the point 33 schivenkbar gelagertsii Boppelhebel 31> 32 "Abi lever arm 31 is provided, connected to the rod 27! [spring 55 tending _s the lever 31» 32 clockwise su turn Ivna against a Back to the stop pin 36 located on the rod 27.

Through a longitudinal slot 37 of the machine side wall is an axis 39 connected to the action key 3S passed through the j when the current pulse from the lever arm 32 is moved downwards and thereby actuates the flas counter. When the electromagnet 22,23 responds, the moves Stango 27 in the direction of the arrow a · The trigger axis 39 from the end of the lever arm 32 which is passed over it

pressed down * the adding machine responds, ie the motor control is closed, the clutch released, the machine makes one revolution and counts the set value. Once the revolution has taken place, the machine and the trigger axis 39 return to their starting position. This is easily possible until the armature 23 is still on. When the current pulse ceases, the control linkage, under the action of a tension spring 40 connected to the lever arm 25, returns to the starting position according to FIG Lever 31 * 32 grinds over the trigger axis 39 »The sowing process can thus" be repeated as often as you like. whereby the duration of the impulse delivery has no meaning for the actual J-dialing process »

Of course, the hiring is not based on what is shown Example limited. So instead of the adding machine, another one, suitably from the beam receivers, can be used 6.7 influenced counter can be used «Me on di © counting button 38 of the Efaseliine 20 acting tax with « tel can also be designed in another suitable manner and be legendary.
