Abstract

The invention relates to a pulse counter in the form of an electromechanical counter with a vibrating-coil drive and a switching armature for stepping on the digit drums which can be triggered by electric pulses. In this arrangement, it is intended to create a particularly space-saving counter which can be produced efficiently and inexpensively as a compact assembly. Prefabricable assemblies should be usable which form functional units and can be inserted complete into a rack provided with receptacles. For this purpose, a pulse counter is used, the drive of which for the switching armature in the form of a switching rocker is effected from a coil rocker which carries on both sides in a symmetrical arrangement with respect to the pivoting axis one coil each at a distance corresponding to the pivoting travel from one stationary permanent magnet each, and polarity and direction of winding of the coils are designed in such a manner that when current is applied, one coil is in each case attracted and the other coil is repelled. <IMAGE>

Description

Die Erfindung betrifft einen Impulszähler als elektromechanisches Zählwerk mit Schwingspulenantrieb mit zwei stationären Permanentmagneten und Schaltanker für durch elektrische Impulse auslösbare Fortschaftung der Ziffemrollen.The invention relates to a pulse counter as an electromechanical counter with a voice coil drive with two stationary permanent magnets and switch armature for the triggering of the digit rollers, which can be triggered by electrical pulses.

Ein derartiger Impulszähler ist aus der EP 00 78 787 A1 bekanntSuch a pulse counter is known from EP 00 78 787 A1

Zählwerke dieser Art werden in Geräten zur Erfassung von Mengen, Zeiten, Stückzahlen u.a. eingesetzt, wobei die Bauart und Größe von besonderer Bedeutung ist Oft erfördert die kleine Bauart solcher Geräte, die in erheblichen Mengen benötigt werden, entsprechend kleine raumsparend und kompakt ausgebildete Zählwerke. Vielfach werden diese Geräte auch aus Batterien versorgt, sodass ein leistungsarm ausgebildeter Antrieb des Zählwerks erforderlich ist, welcher sich entsprechend günstig auf die aus der Batterie erreichbare Impulszahl und damit Betriebsdauer auswirktCounters of this type are used in devices for recording quantities, times, quantities etc. used, the type and size is of particular importance Often, the small design of such devices, which are required in large quantities, promotes correspondingly small space-saving and compactly designed counters. In many cases, these devices are also powered by batteries, so that a low-power drive of the counter is required, which has a correspondingly favorable effect on the number of pulses that can be achieved from the battery and thus the operating time

Ausserdem werden weitere Forderungen bezüglich Festigkeit gegen Stoßen und Rütteln gestellt, was zur Realisierung besondere Gestaltung erfordert und sich die be kannten Lösungen nur aufwendig und teuer fertigen lassen.In addition, further demands are made with regard to strength against impact and shaking, which requires special design for implementation and the known solutions can only be produced in a complex and expensive manner.

Der Erfindung liegt nun die Aufgabe zugrunde ein besonders raumsparendes Zählwerk zu schaffen, welches sich als kompakte Baugruppe rationell und kostengünstig herstellen läßt Dabei sollen vorfertigbare Baugruppen verwendbar sein, welche funktionelle Einheiten bilden und sich komplett in ein mit Aufnahmen versehenes Gestell einbringen lassen. Ferner sollen diese Einheiten für rationelle Fertigung zur automatisierten oder teilautomatisierten Vormontage geeignet und mehrere Ausführungsvarianten realisierbar sein.The invention has for its object to provide a particularly space-saving counter, which can be produced efficiently and inexpensively as a compact assembly. Pre-fabricated assemblies should be used, which form functional units and can be completely inserted into a frame provided with receptacles. Furthermore, these units should be suitable for rational production for automated or partially automated pre-assembly and several design variants should be possible.

Zur Lösung dieser Aufgabe kennzeichnet sich der lmpulszähler nach dem Oberbegriff von Anspruch 1 dadurch, daß der Antrieb des Schaltankers als Schaltwippe von einer Spulenwippe aus erfolgt, welche beidseits in symmetrischer Anordnung zu ihrer Schwenkachse je eine Spule trägt, der jeweils in einem dem Schwenkweg entsprechenden Abstand je einer der stationären Permanentmagnete gegenüberliegt und Polung und Wickelsinn der Spulen so ausgelegt sind, daß bei Bestromung jeweils eine Spule angezogen und die andere Spule abgestoßen wird.To achieve this object, the pulse counter according to the preamble of claim 1 is characterized in that the switching armature is driven as a rocker switch from a coil rocker, which carries a coil on both sides in a symmetrical arrangement to its pivot axis, each at a distance corresponding to the pivot path one of the stationary permanent magnets is opposite each other and the polarity and winding direction of the coils are designed so that one coil is energized and the other coil is repelled when energized.

Hierbei führt Schwenkachse der Spulenwippe zur unwuchtfreien Lagerung durch deren Schwerpunkt, wobei zwei körperlose Backspulen für die Spulenwippe Verwendung finden.Here, the swivel axis of the coil rocker leads to unbalance-free storage through its center of gravity, two disembodied baking coils being used for the coil rocker.

Weitere Einzelheiten ergeben sich aus den Unteransprüchen. Hierbei waren höchstmögliche Unempfindlichkeit gegen Stoß-und Rüttelbeanspruchung bei der Anordnung und Gestaltung zu berücksichtigen. Auch waren die beweglichen Teile massearm und unwuchtfrei zu gestalten, was u.a. bewirkt daß die Leistungsaufnahme die geforderten, geringen Werte erreicht.Further details emerge from the subclaims. The greatest possible insensitivity to impact and vibration stresses had to be taken into account in the arrangement and design. The moving parts were also designed to be low-mass and unbalanced, which among other things causes the power consumption to reach the required, low values.

Ein Impulszähler als elektromechanisches Zählwerk mit Schwingspulenantrieb gemäß der Erfindung ist als bevorzugtes Ausführungsbeispiel in der Zeichnung dargestellt und nachfolgend erläutert und zwar zeigen:

  • Figur 1 bis 3 einen Querschnitt, Draufblick und Längsschnitt durch das Zählwerk,
  • Figur 4 und 5 eine Seitenansicht und Draufsicht eines Zählrollenwerks als kompakte Baugruppe,
  • Figur 6 und 7 einen Ausschnitt und Draufsicht der Spulenwippe als Antriebsgruppe und
  • Figur 8 und 9 eine Seitenansicht und Draufsicht eines Zählrollenwerks in atternativer Bauform.
A pulse counter as an electromechanical counter with a voice coil drive according to the invention is shown as a preferred exemplary embodiment in the drawing and explained below, specifically showing:
  • 1 to 3 show a cross section, top view and longitudinal section through the counter,
  • FIGS. 4 and 5 show a side view and a top view of a counting roller mechanism as a compact assembly,
  • 6 and 7 show a detail and top view of the bobbin rocker as the drive group and
  • 8 and 9 show a side view and a top view of a counter roller mechanism in an alternative design.

Wie aus der Zeichnung in Figur 1 bis 3 ersichtlich ist, dient das Gestell 1 der Aufnahme aller Baugruppen, wie sie in den weiteren Figuren 4 bis 9 dargestellt sind und in am Gestell 1 angebildete Aufnahmen einrastend, einsetzbar sind.As can be seen from the drawing in FIGS. 1 to 3, the frame 1 serves to hold all the assemblies, as shown in the further FIGS. 4 to 9, and can be inserted into the receptacles formed on the frame 1.

In zwei am Gestellboden 2 angeformten, federnden Lagerstellen 3,4, die Bohrungen 5,7 mit den Einführschrägen 6,8 aufweisen, lagert die Spulenwippe 9 mittels der beidseits einstückig angeordneten Lagerzapfen 10,11. Diese Lagerzapfen 10,11 bewirken beim Einsetzen der Spulenwippe 9 durch die Einführschrägen 6,8, daß die Lagerstellen 3,4 ausweichen bis die Lagerzapfen 10,11 in die Bohrungen 5,7 eintauchen und dann zurückfedem. Zur unwuchtfreien Lagerung der Spulenwippe 9 führt deren Schwenkachse gebildet von den Lagerzapfen 10,11 durch den Schwerpunkt Die Spulenwippe 9 dient als Träger der beiden Spulen 12,13, die als Backspulen ausgebildet und auf Spreizhülsen 14,15 in gleichem Abstand vom Schwerpunkt angeordnet sind.In two resilient bearing points 3, 4 formed on the frame base 2, which have bores 5, 7 with the insertion bevels 6, 8, the spool rocker 9 is supported by means of the bearing pins 10, 11 which are arranged in one piece on both sides. These pegs 10, 11 cause the insertion points 6, 8 when inserting the bobbin rocker 9 so that the bearing points 3, 4 dodge until the pegs 10, 11 dip into the bores 5 , 7 and then spring back. For the unbalanced mounting of the bobbin rocker 9, its pivot axis is formed by the journals 10, 11 through the center of gravity. The bobbin rocker 9 serves as a carrier for the two coils 1, 2.13, which are designed as baking coils and are arranged on expanding sleeves 1, 4.15 at the same distance from the center of gravity are.

Wie aus Figur 6 und 7 ersichtlich wird, ist jeweils ein Stopfen 16,17 einstückig mit der Spreizhülse 14,15 verbunden. Die Spulen 12,13 werden zur Montage auf die Spreizhülsen 14,15 gesteckt und die Stopfen 16,17 eingedrückt, wodurch die Spreizhülsen 14,15 aufweiten und die Spulen 12, 13 in ihrer Bohrung festlegen. Außerdem besitzt die Spulenwippe 9 beidendig Mitnehmerzapfen 18,19 zur Antriebsübertragung und Ösen 20,21, durch welche die Spulenanschlüsse 22,23 geführt werden, während die Spulenanschlüsse 24,25 im Bereich der Bohrung 26 überkreuzend mittels Lötung 27 elektrisch leitend verbunden sind. Die Spulenanschlüsse 22,23 werden in loser Schleife bei im Gestell 1 eingesetzter Spulenwippe 9 an die Anschlußstifte 28,29 angelötetAs can be seen from FIGS. 6 and 7, a stopper 16, 17 is connected in one piece to the expansion sleeve 14, 15. The coils 12, 13 are placed on the expansion sleeves 14, 15 for assembly and the plugs 16, 17 are pressed in, as a result of which the expansion sleeves 14, 15 expand and fix the coils 1 2, 1 3 in their bore. In addition, the coil rocker 9 has driver pins 18, 19 on both ends for drive transmission and eyelets 20, 21 through which the coil connections 22, 23 are guided, while the coil connections 24, 25 are connected in an electrically conductive manner in the region of the bore 26 by means of soldering 27. The coil connections 22, 23 are soldered in a loose loop with the coil rocker 9 inserted in the frame 1 to the connection pins 28, 29

Der Spulenwippe 9 gegenüberliegend sind die Permanentmagneten 30,31 im Abstand angeordnet und zwar so auf den Schwenkweg der Spulenwippe 9 abgestimmt, daß beiseitig ein ausreichender Sicherheitsabstand gegeben ist Diese Permanentmagnete 30,31 sind in einem Abschirmblech 32 mit Einprägungen 33,34 fixiert und gehalten und zwar durch ihre eigene Feldstärke, ggfs. sind sie - (30,31) auch zusätzlich aufgeklebt Das Abschirmblech 32 ist in Aufnahmen 35/36 der Seitenwände 37,38 des Gestells 1 eingesetzt Die Polung der Permanentmagnete 30,31 und der Wickelsinn der zugeordneten Spule 12, 13 sind so ausgelegt, daß bei Bestromung jeweils die eine Spule angezogen und die andere Spule abgestoßen wird.Opposite the bobbin rocker 9, the permanent magnets 30, 31 are arranged at a distance, in such a way that they are matched to the swivel path of the bobbin rocker 9, that there is a sufficient safety clearance on both sides. These permanent magnets 30, 31 are fixed and held in a shielding plate 32 with impressions 33, 34 and although by their own field strength, if necessary they are (- 30, 31) also glued on. The shielding plate 32 is inserted in receptacles 35/36 of the side walls 37, 38 of frame 1. The polarity of the permanent magnets 30, 31 and the winding direction of the associated coil 12, 13 are designed so that when one is energized, one coil is attracted and the other coil is repelled.

Die in Figur 4 und 5 dargestellte Baugruppe des Zählwerkes besteht aus der Anfangsrolle 40 mit Schaltrad 41, den Mittelrollen 42 und der Endrolle 43, welche auf der Welle 44 gelagert sind. Auf der parallel dazu angeordneten Welle 45 sind mit den Zahlenrollen 40,42,43 im Eingriff stehende Schatttriebe 46 und die Schaltwippe 47 gelagert Beide Wellen 44,45 sind in entsprechend gleiche Platinen 48,49 eingepreßt, die den Wellenabstand exakt bestimmen. Hierbei sind beide Platinen 48,49 axial so aufgepreßt, daß sich bei allen auf der Welle 44 gelagerten Zahlenrollen 40,42,43 das erforderliche axiale Laufspiel -Rollensatzspiel - ergibt Die Enden beider Wellen 44,45 stehen auf beiden Seiten der Platinen 48,49 vor und zwar zur Aufnahme der Zählerbaugruppe während der Montage und sodann zur Halterung im Gestell 1.The assembly of the counter shown in FIGS. 4 and 5 consists of the initial roller 40 with ratchet wheel 41, the central rollers 42 and the end roller 43, which are mounted on the shaft 4 4. On the arranged parallel to shaft 45 are in engagement with Schattseite drives 46 and the rocker 47, both shafts 44, 4 5 are in accordance with the same circuit boards 48,49 are pressed with the number wheels 40,42,43 supported, determining the shaft distance accurately. Here, both boards 4, 8.49 are axially pressed in such a way that the required axial running play - role set play - results for all numbered rolls 40, 42, 43 supported on the shaft 4 4. The ends of both shafts 44 , 45 are on both sides of the boards 48 , 49 before and specifically for receiving the counter module during assembly and then for mounting in frame 1.

An den Platinen 48,49 sind ferner, wie in Fig. 4/5 und 8/9 ersichtlich, Haltelappen 50 mit Einhängeschlitzen 51 angebildet, in welche endrollenseitig die Basis 53 der U-förmigen Drahtfeder 54 eingesetzt ist Von den federnden Enden 55,56 der Drahtfeder 54, welche zur Sicherung gegen axiales Verschieben abgewinkelt ist, liegt antriebsseitig das eine Federende 55 im Einhängeschlitz 51 der Platine 49, während das andere Federende 56 vorgespannt im Einhängeschlitz 57 der Schaltwippe 47 eingehängt ist. Diese Drahtfeder 54 schaltet nach Impulsende in bekannter Weise den zweiten Halbschritt der Zahlenrollen durch die Schaltwippe 47, die in Fig. 4/5 in einer Zwischenstellung gezeichnet ist.On the boards 48, 49, as is shown in FIGS. 4/5 and 8/9, retaining tabs 50 with hanging slots 51 are formed, in which the base 53 of the U-shaped wire spring 54 is inserted on the end roller side. From the resilient ends 55, 56 the wire spring 54, which is angled to secure it against axial displacement, the drive end has one spring end 55 in the suspension slot 51 of the circuit board 49, while the other spring end 56 is preloaded in the suspension slot 57 of the rocker switch 47. This wire spring 5 4 switches after the end of the pulse in a known manner the second half step of the number rollers by the rocker switch 47, which is shown in Fig. 4/5 in an intermediate position.

Damit ist diese Zählwerk-Baugruppe voll funktionsfähig und kommt beim Einsetzen in das Gestell 1 durch die Mitnehmergabel 58 in Eingriff mit dem Mitnehmerzapfen 19 der Spulenwippe 9. Die beidseitig an der Zählwerk-Baugruppe gegenüber den Platinen 48,49 vorstehenden Wellen 44,45 dienen der Befestigung im Gestell 1, wofür die Wellenenden 45 in den starren Lagersitz 60 der Seitenwände 37,38 eingelegt und die Wellenenden 44 in den Lagersitz 61 im federnden Steg 62 eingerastet werden.Thus, this counter assembly is fully functional and comes into engagement with the driving pin 58 of the spool rocker 9 when inserted into the frame 1 by means of the driving fork 58. The shafts 44, 45 projecting on both sides of the counter assembly relative to the boards 48, 49 serve the purpose Fastening in the frame 1, for which the shaft ends 45 are inserted into the rigid bearing seat 60 of the side walls 37, 38 and the shaft ends 44 are snapped into the bearing seat 61 in the resilient web 62.

Mit weitgehend gleichen Teilen, ausgenommen anders bedruckter Zahlenrollen 40,42 und 43 ist, wie in Fig. 8/9 dargestellt, ein Zählwerk herstellbar, bei welchem die Zahlenrollen auf der anderen Seite des Antriebs angeordnet sind. Dabei greift die Mitnehmergabel 58 der Schaltwippe 47 in den Mitnehmerzapfen 18 der Spulenwippe 9.With largely the same parts, with the exception of differently printed number rollers 40, 42 and 43, a counter can be produced, as shown in Fig. 8/9, in which the number rollers are arranged on the other side of the drive. The driver fork 58 of the rocker switch 47 engages in the driver pin 18 of the coil rocker 9.

Dementsprechend wird auch die U-förmige Drahtfeder 54 in der Platine 48 eingesetzt und deren Drahtenden 55,57 vorspannend in der Platine 49 und in der auf dieser Seite eingebauten Schaltwippe 47 eingehängtAccordingly, the U-shaped wire spring 54 is also used in the circuit board 48 and its wire ends 55, 57 are preloaded in the circuit board 49 and in the rocker switch 47 installed on this side

Zur Befestigung von Zusatzbausteinen, wie Verstärker, Impulsformer oder Zeitimpulsgeber als Hybrid oder auf gedruckter Schaltung ausgeführt, sind an beiden Gestellwänden Führungsschlitze 63,64 vorgesehen. An Durchbrüchen 65,66 am Boden 2 des Gestell 1 führen ggfs. notwendige weitere Anschlüsse des Zusatzbausteins, während die abgewinkelten Anschlußstifte 28,29 direkt an den Baustein angelötet werden.Adapted for attachment of additional components, such as amplifiers, pulse former or timing pulse as a hybrid or printed circuit which guide slots 63.6 4 are provided on both frame walls. Necessary further connections of the additional module lead to openings 65, 66 on the bottom 2 of the frame 1, while the angled connecting pins 28, 29 are soldered directly to the module.

Zur Abdeckung des Zählwerkes dient die Kappe 67, welche aus durchsichtigem Kunststoff hergestellt, im Ablesebereich als Lupe 68 ausgebildet, die Ziffern vergrößert und mittels der Rastnasen 69,70 in die Durchbrüche 71,72 der Gestettseitenwände 37,38 einrastbar ist Ein am Gestellboden 2 umlaufender Dichtwulst 73 legt sich so an den in der Kappe 67 umlaufend angebildeten Ansatz 74 an, daß eine für das Vergießen erforderliche umlaufende Rille 75 gebildet wird.To cover the counter, the cap 67, which is made of transparent plastic, is formed in the reading area as a magnifying glass 68, the digits are enlarged and can be snapped into the openings 71, 72 of the frame side walls 37, 38 by means of the locking lugs 69, 70 Sealing bead 73 rests against the shoulder 74 formed in the cap 67 in a circumferential manner in such a way that a circumferential groove 75 required for the potting is formed.
