Description

Die Erfindung bezieht sich auf die Anwendung einer auf vielen Gebieten der industriellen Produktion üblichen Sicherheits-Ausschaltvorrichtung auf Schokoladen-Walzwerke, bei denen es besonders wichtig ist, eine Verschlechterung des Aromas und der Güte der Schokoladenmasse durch Überhitzung der Walzen zu vermeiden. Um dieses Ziel einer sorgfältigen Betriebsüberwachung mit dem Vorteil des Wegfalls jeder menschlichen Kontrolle zu erreichen, soll erfindungsgemäß zum Hauptmotorschalter ein ' gegebenenfalls aus mehreren in Reihe geschalteten Einzelschaltern bestehendes, auf die unzulässige Herbeiführung eines oder mehrerer der nachstehenden unerwünschten Betriebszustände ansprechendes Sicherheits-Ausschaltaggregat parallel geschaltet sein: a) Überschreitung der Kühlwasseraustrittstemperatur, b) Unterschreitung der Kühlwassermenge und c) Verringerung der Stärke des von den Walzen mitgenommenen Massefilms.The invention relates to the use of one in many fields the safety cut-off device used in industrial production on chocolate rolling mills, where it is particularly important, a deterioration in flavor and quality to avoid the chocolate mass from overheating the rollers. To this goal one careful operational monitoring with the benefit of eliminating any human To achieve control, according to the invention, the main motor switch on 'if necessary consisting of several individual switches connected in series to the impermissible one Causing one or more of the following undesirable operating conditions Appropriate safety switch-off unit must be connected in parallel: a) Exceeding the cooling water outlet temperature, b) falling below the cooling water quantity and c) Reduction in the thickness of the bulk film carried along by the rollers.

Verschiedene Ausführungsmöglichkeiten der Anordnung der Sicherheits-Ausschaltvorrichtung nach der Erfindung sind aus den ohne weiteres verständlichen Zeichnungen ersichtlich, und zwar zeigt Fig. i die Impulsgeber für Mengen- bzw. Temperaturimpulse innerhalb der Kühlwasseraustrittsleitung, Fig.2 die Impulsgeber, die auf die Stärke des Schokoladenfilms auf den Walzen ansprechen, sowie Fig. 3 ein Schaltschema der Anlage.Various design options for the arrangement of the safety cut-out device according to the invention can be seen from the easily understandable drawings, namely Fig. i shows the pulse generator for quantity or temperature pulses within the cooling water outlet line, Fig.2 the pulse generator, which affects the thickness of the chocolate film respond to the rollers, and Fig. 3 is a circuit diagram of the system.

Je nach der erwünschten Genauigkeit der Kontrolle ist entweder in nur einem einzigen Kühlwasserauslauf 13° bis 13b einer Walze 3 der üblichen Mehrfachwalzwerke oder in sämtliche Kühlwasserausläufe im Sinne der Fig. i ein einen einstellbaren Schalter 14 darstellender Thermostat und unter Umständen auch gleichzeitig ein von der in der Zeiteinheit durchströmenden Kühlwassermenge beeinflußter Kipphebelschalter 15 eingebaut. Beide Impulsgeber wirken, unter Umständen über Relais (vgl. Fig. 3), auf parallel zum Hauptmotorschalter 31 in Reihe geschaltete Einzelschalter ein, die sich bei einer unzulässigen Erhöhung der mit dem Thermostaten gemessenen Kühlwasseraustrittstemperatur bzw. bei einer Verminderung der Kühlwasserdurchlaufmenge und ihres auf den Kipphebel 16 und 17 einwirkenden Strömungsdruckes selbsttätig öffnen. Der Kipphebel 16, 17 ist mit seiner Achse 18 an einem Gehäuse i9 (vgl. Fig. i) gelagert, das einen Gegenkontakt 2o und einen Anschlag für die Begrenzung der Ausschaltbewegung des Kipphebels aufweist. Fällt der Temperaturimpuls aus irgendwelchen Gründen aus, so kann das Ausschalten des Motorstromes auch schon bei Verringerung der Kühlwasserdurchflußmenge selbsttätig erfolgen.Depending on the desired accuracy of the control, either in only a single cooling water outlet 13 ° to 13b of a roller 3 of the usual multiple rolling mills or in all cooling water outlets in the sense of FIG Switch 14 representing thermostat and possibly at the same time one of the amount of cooling water flowing through in the unit of time influenced toggle switch 15 built in. Both pulse generators act, possibly via relays (see Fig. 3), on individual switches connected in series parallel to the main motor switch 31, which occurs in the event of an impermissible increase in the cooling water outlet temperature measured by the thermostat or with a reduction in the cooling water flow rate and its on the rocker arm 16 and 17 acting flow pressure open automatically. The rocker arm 16, 17 is mounted with its axis 18 on a housing i9 (see. Fig. i), which has a counter contact 2o and has a stop for limiting the switch-off movement of the rocker arm. If the temperature pulse fails for any reason, it can be switched off of the motor current automatically even when the cooling water flow rate is reduced take place.

Ein ähnlicher Kipphebelschalter ist nach Fig. 2 in den auf einer bestimmten Breite durch einen Schaber 22 von einer Walze 3 entnommenen Schokoladenmassestrom eingeschaltet, dessen Verringerung in ähnlicher Weise den aus Fig. 3 ersichtlichen dritten Einzelschalter zum Öffnen des Motorstromkreises und Ausschalten auch dann zwingt, wenn die anderen Impulsgeber wirkungslos bleiben. Dieser letztere Kipphebelschalter weist einen Hebel 24 mit Gegengewicht 25 auf, der um eine Achse 26 eines Gehäuses 27 zwischen einem Kontakt 28 und einem Begrenzungsanschlag für die Ausschaltbewegung des Kipphebels schwingt.A similar toggle switch is shown in Fig. 2 in the on a particular Width of chocolate mass flow removed from a roller 3 by a scraper 22 switched on, its reduction in a manner similar to that shown in FIG Third individual switch to open the motor circuit and then switch it off forces if the other pulse generators remain ineffective. This latter toggle switch has a lever 24 with a counterweight 25, which is about an axis 26 of a housing 27 between a contact 28 and a limit stop for the switch-off movement of the rocker arm swings.

Die elektrischen Übertragungsmittel und die Mittel zur Vergrößerung der geringen Impulskräfte auf die für die Schalterverstellung notwendige Stärke sind für die Beurteilung der Erfindung unwichtig; man kann sich dazu der heutzutage üblichen Hilfsmittel der elektrischen Schalttechnik bedienen.The means of electrical transmission and the means of enlargement the low impulse forces to the strength necessary for the switch adjustment are not important for assessing the invention; you can do this nowadays Use the usual aids in electrical switching technology.
