Description

Schrittschaltwerk mit wahlweise veränderlicher Schaltschrittlänge Die Erfindung betrifft ein Schrittsehaltwerk mit wahlweise veränderlicher Schaltschrittlänge und an Kniehebeln befestigten Klinken zur Betätigung des Schaltrades, zum Steuern und Bewegen von Maschinenelementen an Arbeitsmaschinen, insbesondere für Bürstenstanzmaschinen. Bisher wurden die Bürstenstanzmaschinen durch Schablonenräder gesteuert. Die Schablonenräder sind nur für eine bestimmte Maschine passend und können nur bei Stillstand der Arbeitsmaschine angefertigt werden.Stepping mechanism with optionally variable switching step length The invention relates to a step switch mechanism with an optionally variable switching step length and pawls attached to toggle levers for actuating the ratchet wheel for steering and moving machine elements on work machines, in particular for brush punching machines. Up to now, the brush punching machines were controlled by template wheels. The template wheels are only suitable for a specific machine and can only be used when the machine is at a standstill be made.

Es sind Schrittschaltwerke mit wahlweise veränderlicher Schrittlänge und Klinken zum Betätigen des Schaltrades bekannt, bei denen die Klinken an Kniehebeln befestigt sind. Dabei erfolgt die Versteilung der Schrittlänge über eine Schraubspindel. Dadurch ist eine schnelle und zuverlässige Verstellung der Sebaltschrittlängen in genau festgelegten reproduzierbaren, stark schwankenden Größen nicht möglich.There are stepping mechanisms with optionally variable step length and pawls for operating the ratchet wheel are known, in which the pawls on toggle levers are attached. The step length is steepened using a screw spindle. This enables quick and reliable adjustment of the Sebalt step lengths in precisely defined, reproducible, strongly fluctuating sizes are not possible.

Aufgabe der Erfindung ist ,es .daher, ein Schrittschaltwerk der eingangs genannten Art zu schaffen, bei dem schnell und zuverlässig ein Schaltrad durch Schaltschritte beliebiger, festgelegter Größe in während des Betriebs vorzusehender beliebiger Folge betätigt wird.The object of the invention is, therefore, a stepping mechanism of the initially to create the type mentioned, in which a ratchet wheel quickly and reliably by switching steps of any specified size in any to be provided during operation Sequence is operated.

Zur Lösung,dieser Aufgabe sind zum Betätigen des Schaltrades mehrere Kniehebel hintereinandergeschaltet angeordnet, die einzeln oder in Gruppen .eine gemeinsame Schaltklinke betätigen.To solve this problem, several are required to operate the ratchet wheel Toggle levers arranged one behind the other, individually or in groups operate the common ratchet.

Zur Erläuterung ist ein Schrittschaltwerk nach der Erfindung an Hand einer Zeichnung beschrieben. Mehrere Kniehebel 1, 2, 3 sind miteinander verbunden. Der Kniehebel l ist an seinem freien Ende ortsfest verankert. Am Kniehebel 3 ist die Schaltklinke 4 befestigt, die in ein Schaltrad 5 eingreift. In der Zeichnung ist der jeweils folgende Kniehebel etwas größer gewählt, gegebenenfalls können die Kniehebel aber auch gleich groß sein. In Ruhestellung sind alle Kniehebel gestreckt. Wenn die Kniehebel 1, 2, 3 einzeln oder in Gruppen betätigt werden, werden die verschieden großen Schaltschritte hervorgerufen. Das Beugen und Strecken .der Kniehebel 1, 2, 3 wird im Rhythmus der Arbeitsmaschine mittels Schwinghebel 8 -und Schieber 11 ausgeführt. Ein Lochband 9 bringt die Kniehebel in Arbeitsstellung, ein Schieber 10 bewirkt, wenn erforderlich, den Rücklauf des Schaltrades. Die Schalträder sind mit einem Zahnrad 6 verbunden, in das die Zahnstange 7 eingreift, um die mit ihr verbundenen Maschinenelemente zu bewegen.A step-by-step mechanism according to the invention is provided for explanation described in a drawing. Several toggle levers 1, 2, 3 are connected to one another. The toggle lever l is fixedly anchored at its free end. On the knee lever 3 is the pawl 4 is attached, which engages in a ratchet 5. In the drawing if the following knee lever is chosen to be slightly larger, the But toggle levers must also be of the same size. In the rest position, all knee levers are extended. If the toggle levers 1, 2, 3 are operated individually or in groups, they become different caused large switching steps. The bending and stretching of the knee levers 1, 2, 3 is carried out in the rhythm of the machine by means of rocker arm 8 and slide 11. A perforated strip 9 brings the toggle lever into the working position, a slide 10 causes if necessary, the return of the ratchet wheel. The ratchet wheels are with a Gear 6 connected, in which the rack 7 engages to the associated with her To move machine elements.

Der Vorteil des veränderlichen Schrittschaltwerkes besteht darin, daß man die Schaltschrittgröße während des Betriebes mittels Lochband vorwählen kann. Außerdem sind die Schaltzeiten bei allen Schrittgrößen gleich. Die Beschleunigungen am Anfang der Schaltbewegung sind klein.The advantage of the variable stepping mechanism is that that you preselect the switching step size during operation using a perforated strip can. In addition, the switching times are the same for all step sizes. The accelerations at the beginning of the switching movement are small.
