Description

Die Erfindung betrifft eine Vorrichtung zur Übergabe von in einem Vorratsbehälter gelagertem, aus Einzelprodukten gebildetem Schüttgut an eine die Einzelprodukte in die Näpfe einer kontinuierlich oder getaktet bewegten Folienbahn transferierende Transfereinrichtung, mit einer dem Produktauslauf des Vorratsbehälters stromab nachgelagerten Lochplatte, die auf einem Grundgestell angeordnet ist.The invention relates to a device for transferring stored in a reservoir, formed from individual products bulk material to the individual products in the wells of a continuously or clocked moving film web transfer transfer device, with a product outlet of the reservoir downstream downstream perforated plate, which is arranged on a base frame.

Derartige Vorrichtungen finden insbesondere Verwendung in der Arbeitsstation von Thermoformmaschinen, bei der die als Schüttgut in dem Vorratsbehälter bereitgestellten Einzelprodukte weiterverarbeitet werden, um deren Abfüllung in die Näpfe der Folienbahn zu ermöglichen. Dazu werden die Einzelprodukte aus dem Vorratsbehälter durch den Produktauslauf auf die Lochplatte überführt.Such devices are particularly used in the workstation of thermoforming machines, in which the individual products provided as bulk material in the reservoir are further processed to allow their filling into the wells of the film web. For this purpose, the individual products are transferred from the reservoir through the product outlet to the perforated plate.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, dass die Arbeitsweise der Transfereinrichtung vereinfacht wird.The invention has the object of providing a device of the type mentioned in such a way that the operation of the transfer device is simplified.

Diese Aufgabe wird nach der Erfindung bei einer Vorrichtung der eingangs genannten Art dadurch gelöst, dass stromab zum Produktauslauf oberhalb der Lochplatte ein um eine Schwenkachse drehbarer Schüttgutnivellierer angeordnet ist.This object is achieved according to the invention in a device of the type mentioned in that downstream of the product outlet above the perforated plate is arranged around a pivot axis rotatable bulk material leveler.

Dieser Schüttgutnivellierer hat den zweifachen Vorteil, dass zum einen die aus dem Produktauslauf des Vorratsbehälters austretenden Einzelprodukte von einer Produktsäule in einen Produktteppich umgewandelt werden, und zum anderen die Auffächerung des Produktteppichs auf die gesamte Breite der Lochplatte unterstützt wird, so dass die durch die Lochplatte bereitgestellte Fläche zur Staub- und Bruchausscheidung effektiv genutzt werden kann.This bulk leveler has the dual advantage that on the one hand, the emerging from the product outlet of the reservoir individual products are converted from a product column in a product carpet, and on the other hand, the fanning of the product carpet is supported on the entire width of the perforated plate, so that provided by the perforated plate Area can be effectively used for dust and Bruchausscheidung.

Zur schonenden Behandlung der aus der Produktsäule austretenden und in den Produktteppich überzuführenden Einzelprodukte ist an dem der Lochplatte zugewandten freien Ende des Schüttgutnivellierers eine elastische Lippe angeordnet .For gentle treatment of emerging from the product column and transferred to the product carpet individual products, an elastic lip is arranged on the perforated plate facing the free end of Schüttgutnivellierers.

Indem die Drehlage des Schüttgutnivellierers durch ein Fixierelement feststellbar ist, besteht die einfache Möglichkeit, die Drehlage des Schüttgutnivellierers in Abhängigkeit der Größe der Einzelprodukte, insbesondere von deren Höhe, festzulegen.By the rotational position of Schüttgutnivellierers is determined by a fixing element, there is the easy way, the rotational position of the bulk level depending on the size of the individual products, in particular the amount set.

Da insbesondere im pharmazeutischen Bereich sehr strenge Reinheitsanforderungen zu beachten sind, ist es auch erforderlich, bei einem Produktwechsel die Vorrichtung und dabei insbesondere die Lochplatte sowie den Schüttgutnivellierer reinigen zu können. Es ist daher zweckmäßig, dass der Schüttgutnivellierer lösbar an dem Grundgestell angeschlossen ist.Since very strict purity requirements are to be observed especially in the pharmaceutical field, it is also necessary to be able to clean the device and in particular the perforated plate and the bulk material leveler during a product change. It is therefore expedient that the bulk material leveler is detachably connected to the base frame.

Um eine möglichst einfache Konstruktion zu erzielen, ist das Fixierelement durch eine Klemmschraube mit einem Knebelrad gebildet, die in eine nach oben offene Schraubenaufnahme einsetzbar ist.In order to achieve the simplest possible construction, the fixing element is formed by a clamping screw with a Knebelrad, which is insertable in an upwardly open screw receptacle.

Für eine feinfühlige Positionierung des Abstandes der elastischen Lippe von der Lochplatte ist an der Klemmschraube ein Justierhebel angeordnet.For a sensitive positioning of the distance of the elastic lip of the perforated plate an adjusting lever is arranged on the clamping screw.

Eine weitere bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass dem Grundgestell mindestens eine in einem Kulissenträger mit einer geneigt zur Vertikalen verlaufenden Kulisse gelagerte Klemmleiste zugeordnet ist, dass die Kulisse durch eine endseitig offene Steuerkurve gebildet ist, in die die Klemmleiste mit einem Führungsstift einsetzbar ist, und dass die Klemmleiste auf der der Kulisse abgewandten Seite ein die Klemmleiste gegen die Plattenhalterung spannendes Spannmittel aufweist. Diese Ausführungsform ist insbesondere auf eine einfache Reinigungsmöglichkeit optimiert und bietet zudem den Vorteil, dass die Lochplatte wenig belastbar gestaltet sein kann, da durch die Klemmleiste eine Beaufschlagung von oben erfolgt, bei der die Lochplatte gegen die Plattenhalterung gedrückt wird.A further preferred embodiment of the invention is characterized in that the base frame is associated with at least one mounted in a link carrier with a sloping to the vertical backdrop mounted terminal block, that the link is formed by an open end control cam, in which the terminal block can be used with a guide pin , And that the terminal strip on the side facing away from the backdrop has a clamping strip against the plate holder exciting clamping means. This embodiment is particularly optimized for easy cleaning and also has the advantage that the perforated plate can be designed to be less resilient, since the terminal strip is acted upon from above, in which the perforated plate is pressed against the plate holder.

Eine besonders sichere Halterung der Lochplatte wird erzielt, wenn mehrere Klemmleisten vorgesehen sind in einer den Seitenrändern der Lochplatte zugeordneten Anordnung, wobei durch diese Gestaltung auch ein Verkippen der Lochplatte ausgeschlossen ist. Zur Steigerung der Effektivität der Vorrichtung besteht weiterhin die Möglichkeit, dass mehrere Lochplatten vorgesehen sind in einer senkrecht zur Förderrichtung liegenden Reihung. Bei dieser Ausführungsform bietet es sich dann an, dass der Schüttgutnivellierer mindestens eine Aufnahme für eine der Klemmleisten aufweist, um eine Verteilung des Produktteppichs zwischen die Klemmleisten auf die Lochplatte zu ermöglichen, so dass der Schüttgutnivellierer nicht vor dem Anfang der Klemmleisten positioniert sein muss.A particularly secure mounting of the perforated plate is achieved if a plurality of clamping strips are provided in an arrangement associated with the side edges of the perforated plate, whereby this design also prevents tilting of the perforated plate. To increase the effectiveness of the device is still the possibility that a plurality of perforated plates are provided in a direction perpendicular to the conveying direction Reihung. In this embodiment, it then makes sense that the bulk material leveler has at least one receptacle for one of the clamping bars to allow distribution of the product carpet between the clamping bars on the perforated plate, so that the bulk material leveler does not have to be positioned in front of the beginning of the clamping bars.

Weiterhin ist vorgesehen, dass dem Grundgestell mindestens ein Vibrationsantrieb zur Förderung der Produkte von dem Produktauslauf zu der Transfereinrichtung zugeordnet ist, um somit effektiv die durch die Lochplatte bereitgestellte Länge zur Staub- und Bruchausscheidung ausnutzen zu können und eine kurze Transferzeit zwischen dem Produktauslauf und der Transfereinrichtung zu erzielen.Furthermore, it is provided that the base frame is assigned at least one vibration drive for conveying the products from the product outlet to the transfer device, so as to be able to effectively utilize the length provided by the perforated plate for dust and breakage elimination and a short transfer time between the product outlet and the transfer device to achieve.

Thermoformmaschinen werden insbesondere in der pharmazeutischen Industrie dazu verwendet, Einzelprodukte wie Tabletten, Dragees, Pillen oder dergleichen in Blisterpackungen zu verpacken, wozu zunächst in der Thermoformmaschine von einer Vorratsrolle als Folienbahn eine Formfolie abgezogen und einer Heizstation zugeführt wird, in der die Formfolie auf Verformtemperatur erhitzt und einer Formstation zugeführt wird, in der die Näpfe der Blisterpackungen ausgebildet werden. In die so ausgebildeten Näpfe müssen dann die Einzelprodukte transferiert werden, die dafür als Schüttgut bereitgestellt werden. Um die Überführung der Einzelprodukte aus dem Schüttgut in die Näpfe der Folienbahn zu vereinfachen, dient die erfindungsgemäße Vorrichtung (Fig. 1) als Koppelglied zwischen dem Vorratsbehälter 1 und der die Einzelprodukte in die Näpfe der Folienbahn transferierenden Transfereinrichtung.Thermoforming machines are used in particular in the pharmaceutical industry to package individual products such as tablets, dragees, pills or the like in blister packs, for which initially a thermoforming machine is withdrawn from a supply roll as a film web and fed to a heating station in which the mold film is heated to deformation temperature and a forming station is fed, in which the wells of the blister packs are formed. In the so-trained wells then the individual products must be transferred, which are provided as bulk material. In order to simplify the transfer of the individual products from the bulk material into the wells of the film web, the device according to the invention ( Fig. 1 ) as a coupling member between the reservoir 1 and the individual products in the wells of the film web transfer transfer device.

Die erfindungsgemäße Vorrichtung umfasst dazu neben dem Vorratsbehälter 1 mit seinem Produktauslauf 2 eine auf einer Plattenhalterung 3 lösbar und auswechselbar angeordnete Lochplatte 4, die dem Produktaustauf 2 stromab nachgelagert ist. In dem gezeigten Ausführungsbespiel sind zwei Lochplatten 4 in einer senkrecht zur Förderrichtung der Einzelprodukte liegenden Reihung vorhanden, so dass sich dadurch in sehr einfacher Weise eine effektive große Nutzbreite ergibt. Jede Lochplatte 4 weist eine Mehrzahl von an den Durchmesser und die Form der Einzelprodukte angepassten Löchern auf, die intakte Einzelprodukte auf der Oberfläche der Lochplatte 4 zurückhalten, aber das Ausscheiden von Bruch und Staub ermöglichen. Auf der den Einzelprodukten abgewandten Seite der Lochplatten 4 sind Versteifungsrippen 5 (Fig. 7b) ausgebildet, die von den Seitenrändern geneigt nach innen verlaufen und dadurch viereckige Plattenbereiche 6 voneinander trennen, wobei nur in den Plattenbereichen 6 zwischen den Versteifungsrippen 5 die Löcher ausgebildet sind. An dem in Förderrichtung vorderen und hinteren Ende der Lochplatten 4 sind Auflageflächen 7 ohne Versteifungsrippen 5 vorgesehen, die einer genau definierten Auflage der Lochplatte 4 in dem Grundgestell 24 dienen bei einer verbesserten Ankopplung an einen Vibrationsantrieb, der zur Förderung der Produkte von dem Produktauslauf 2 zu der Transfereinrichtung vorgesehen ist. Da in einem Grundgestell 24 die Mehrzahl der Lochplatten 4 angeordnet werden kann, ist in der Regel ein Vibrationsantrieb ausreichend, so dass sich dadurch ein entsprechender Kostenvorteil ergibt. Ergänzend zur Unterstützung des Vibrationsantriebes kann selbstverständlich auch das Grundgestell 24 in Förderrichtung geneigt verlaufen, um so die Wirkung der Schwerkraft auszunutzen.The device according to the invention comprises, in addition to the storage container 1 with its product outlet 2, a perforated plate 4 detachably and exchangeably arranged on a plate holder 3, which is downstream of the product outlet 2. In the exemplary embodiment shown, two perforated plates 4 are present in a row perpendicular to the conveying direction of the individual products, so that this results in an effective, large usable width in a very simple manner. Each perforated plate 4 has a plurality of holes adapted to the diameter and the shape of the individual products, which retain intact individual products on the surface of the perforated plate 4, but allow the separation of breakage and dust. On the side facing away from the individual products of the perforated plates 4 are stiffening ribs 5 ( Fig. 7b ) are formed, which extend from the side edges inclined inwardly and thereby quadrilateral plate areas 6 separate from each other, wherein only in the plate areas 6 between the stiffening ribs 5, the holes are formed. At the front and rear end of the perforated plates 4 in the conveying direction bearing surfaces 7 are provided without stiffening ribs 5, which serve a well-defined edition of the perforated plate 4 in the base frame 24 with an improved coupling to a vibration drive to promote the products of the product outlet 2 the transfer device is provided. Since in a base frame 24, the majority of the perforated plates 4 can be arranged, a vibration drive is usually sufficient so that this results in a corresponding cost advantage. In addition to the support of the vibration drive can of course also run the base frame 24 inclined in the conveying direction, so as to take advantage of the effect of gravity.

Die Fläche direkt unter dem Produktauslauf 2 kann nicht zur Bruchausscheidung benutzt werden, da die auf der Lochplatte 4 aufliegenden Einzelprodukte von oben durch die darüber liegende Produktsäule auf die Lochplatte 4 gedrückt würden und die Kanten der Löcher und die Vibrationsbewegungen der Lochplatte 4 die Einzelprodukte beschädigen könnten. Der Bereich unterhalb des Produktauslaufs 2 muss daher frei von Löchern bleiben und geht somit für die Bruchausscheidung verloren, so dass sich dadurch eine Verlängerung der Lochplatte 4 ergibt, um eine vollständige Produktausscheidung zu erreichen. Als Rahmenbedingungen bestanden daher die Forderungen nach einem möglichst geringen Platzbedarf bei einer möglichst hohen Leistungsfähigkeit. Das Erreichen dieser Ziele wird dadurch gefördert, dass die Austrittsöffnung 21 des Produktauslaufs 2 eine an einem Rechteck orientierte Grundform aufweist mit einer der Breite der Lochplatte 4 angenäherten Breite und einer an der Größe der Einzelprodukte ausgerichteten Länge, wobei die Lochplatte 4 unterhalb des Produktauslaufs eine mit der Länge der Austrittsöffnung 21 korrespondierende Produkteinlauffläche 22 frei von Löchern aufweist. Bei der Vorrichtung ist also vorgesehen, dass möglichst die gesamte Breite der Lochplatte 4 für die Produktausscheidung ausgenutzt wird bei dem Aufbringen der Einzelprodukte auf die Lochplatte 4, so dass sich daraus eine entsprechende Anpassung der Austrittsöffnung 21 des Produktauslaufs 2 ergibt. Durch die entsprechende Wahl der Form der Austrittsöffnung 21 ist die Länge des löcherfreien Bereiches der Lochplatte 4, also der Produkteinlauffläche 22, begrenzt und auch die Fläche minimiert, die nicht zur Bruchausscheidung beiträgt, da zunächst die Einzelprodukte sich von den Rändern des Produktauslaufes 21 bis zu den Rändern der Lochplatte 4 verteilen müssen (Fig. 8). Als günstig hat es sich erwiesen, wenn die Austrittsöffnung 21 rechteckig gestaltet ist mit einer 60 bis 95%, insbesondere 75 bis 85% der Breite der Lochplatte 4 entsprechenden Breite und dem 2- bis 12-fachen, insbesondere dem 5-bis 8-fachen der Größe der Produkte entsprechenden Länge, wobei die Produkteinlauffläche 22 die 3- bis 8-fache Größe der Austrittsöffnung 21 aufweist.The area directly under the product outlet 2 can not be used for fractional discharge, since the resting on the perforated plate 4 individual products would be pressed from above through the overlying product column on the perforated plate 4 and the edges of the holes and the vibration movements of the perforated plate 4 could damage the individual products , The area below the product outlet 2 must therefore remain free of holes and is thus lost for the fractional precipitation, thereby resulting in an extension of the perforated plate 4, in order to achieve a complete product separation. As conditions therefore the demands existed for a small space requirement with one highest possible performance. The achievement of these objectives is promoted by the fact that the outlet opening 21 of the product outlet 2 has a rectangular shape oriented to a width of the perforated plate 4 approximate width and aligned to the size of the individual products length, the perforated plate 4 below the product outlet with a Having the length of the outlet opening 21 corresponding product inlet surface 22 free of holes. In the device, it is thus provided that as far as possible the entire width of the perforated plate 4 is utilized for the product separation in the application of the individual products on the perforated plate 4, so that there is a corresponding adjustment of the outlet opening 21 of the product outlet 2. By appropriate choice of the shape of the outlet opening 21, the length of the hole-free area of the perforated plate 4, so the product inlet surface 22, limited and minimizes the area that does not contribute to breakage elimination, since initially the individual products from the edges of the product outlet 21 to distribute the edges of the perforated plate 4 ( Fig. 8 ). It has proven to be advantageous if the outlet opening 21 is designed rectangular with a 60 to 95%, in particular 75 to 85% of the width of the perforated plate 4 corresponding width and 2 to 12 times, in particular 5 to 8 times The size of the products corresponding length, wherein the product inlet surface 22 has 3 to 8 times the size of the outlet opening 21.

Bei der Überführung der Einzelprodukte aus dem Vorratsbehälter 1 zu der Transfereinrichtung ist es wichtig, dass die Einzelprodukte auf der Lochplatte 4 nur einlagig aufliegen. Daher ist stromab zum Produktauslauf 2 oberhalb der Lochplatte 4 ein um eine Schwenkachse 8 drehbarer Schüttgutnivellierer 9 angeordnet, der lösbar an dem Grundgestell 24 angeschlossen ist, um den Wechsel der unterhalb des Schüttgutnivellierers 9 befindlichen Lochplatten 4 zu ermöglichen. Der Schüttgutnivellierer 9 selber weist an seinem der Lochplatte 4 zugewandten freien Ende eine elastische Lippe 10 auf, um eine schonende Behandlung der Einzelprodukte zu gewährleisten; die Drehlage des Schüttgutnivellierers 9 selber ist durch ein Fixierelement 11, nämlich eine Klemmschraube mit einem Knebelrad, festellbar, um eine Anpassung an die Größe der Einzelprodukte zu ermöglichen (Fig. 10). An der Klemmschraube selber ist ein Justierhebel 12 angeordnet. Bei einem Wechsel der in die Näpfe der Folienbahn zu verpackenden Einzelprodukte ist gleichfalls ein Wechsel der Lochplatte mit an die Form und Größe der neuen Einzelprodukte angepassten Löchern erforderlich, so dass zur Erzielung möglichst kurzer Rüstzeiten der erfindungsgemäßen Vorrichtung ein Wechsel einfach, schnell und möglichst nur durch eine Person möglich sein soll. Für den Wechsel der Lochplatten 4 wird daher zunächst die Klemmschraube gelöst und mit dem Justierhebel 12 der Schüttgutnivellierer 9 so verdreht, dass dieser aus einer nach oben offenen Schraubenaufnahme 13 nach oben entnommen werden kann.When transferring the individual products from the storage container 1 to the transfer device, it is important that the individual products rest on the perforated plate 4 in only one layer. Therefore, downstream of the product outlet 2 above the perforated plate 4, a bulk material leveler 9 rotatable about a pivot axis 8 is arranged which is detachably connected to the base frame 24 in order to enable the change of the perforated plates 4 located underneath the bulk material leveler 9. The bulk leveler 9 itself has at his the Perforated plate 4 facing the free end of an elastic lip 10 to ensure a gentle treatment of the individual products; the rotational position of the bulk material leveler 9 itself can be adjusted by a fixing element 11, namely a clamping screw with a toggle wheel, in order to allow adaptation to the size of the individual products ( Fig. 10 ). On the clamping screw itself an adjusting lever 12 is arranged. When changing the individual products to be packed in the wells of the film web, a change of the perforated plate is also required with adapted to the shape and size of the new individual products holes, so that to achieve the shortest possible set-up of the device according to the invention a simple, fast and possibly only by a person should be possible. For the replacement of the perforated plates 4, therefore, the clamping screw is first loosened and twisted with the adjusting lever 12 of the bulk material leveler 9 so that it can be removed from an upwardly open screw holder 13 upwards.

Die einfache Auswechselbarkeit der Lochplatten 4 ist dann gegeben durch die Verwendung an der Plattenhalterung 3 als ein Kulissenträger angeordneter Klemmleisten 14. Jede Klemmleiste 14 ist in dem Kulissenträger 15 mit einer geneigt zur Vertikalen verlaufenden Kulisse 16 gelagert, wobei die Kulisse 16 durch eine endseitig offene Steuerkurve 17 gebildet ist, in die die Klemmleiste 14 mit einem Führungsstift 18 einsetzbar ist. Auf der der Kulisse 16 abgewandten Seite der Klemmleisten 14 ist ein Spannmittel, nämlich eine Spannschraube 19, angeordnet, die in einem nach unten gegen die Vertikale geneigt geführten Schraubenlager 23 eingreift, wobei die Neigungsrichtung der Kulisse 16 der Neigungsrichtung der Spannschraube 19 entspricht, so dass bei einem Verdrehen der Spannschrauben 19 in Spannrichtung die Klemmleiste 14 insgesamt entsprechend der Neigung nach unten gezogen wird und die Lochplatte 4 gegen die Plattenhalterung 3 klemmt. Wiederum zur Verbesserung der Reinigungsmöglichkeit ist die Spannschraube 19 lösbar an der Klemmleiste 14 befestigt (Figuren 6a bis 6c). Die Figuren 1 bis 3 zeigen, dass mehrere Klemmleisteln 14 vorgesehen sind in einer den Seitenrändern der Lochplatte 4 zugeordneten Anordnung. Da bei dem gezeigten Ausführungsbeispiel zwei nebeneinander angeordnete Lochplatten 4 vorhanden sind, dient die mittlere Klemmleiste 14 der Beaufschlagung der zwei Seitenränder der linken und der rechten Lochplatte 4. Die Präsenz der mittleren Klemmleiste 14 erzwingt darüber hinaus auch die Ausbildung einer Aufnahme 20 in dem Schüttgutnivellierer 9. Nach dessen Entfernen können die Spannschrauben 19 gelöst und die Klemmleisten 14 in der Kulisse 16 verschoben werden, so dass der Führungsstift 18 aus der endseitig offenen Steuerkurve 17 entnommen und damit die Klemmleiste 14 von der Plattenhalterung 3 entfernt werden kann. Die Lochplatten 4 sind damit frei zugänglich und können entnommen und durch andere Lochplatten 4 ersetzt werden, für die dann lediglich die zuvor gereinigten Klemmleisten 14 wieder mit ihren Führungsstiften 18 in die Steuerkurve 17 eingesetzt und auf die Lochplatten 4 verschwenkt werden müssen zur nachfolgenden Klemmung mittels der Spannschraube 19.The simple interchangeability of the perforated plates 4 is then given by the use of the plate holder 3 as a slide support arranged terminal strips 14. Each terminal block 14 is mounted in the slide carrier 15 with a sloping to the vertical backdrop 16, wherein the gate 16 through an open end cam 17 is formed, in which the terminal block 14 with a guide pin 18 is used. On the side facing away from the backdrop 16 of the terminal strips 14 is a clamping means, namely a clamping screw 19, which engages in a downwardly inclined to the vertical guided screw bearing 23, wherein the inclination direction of the link 16 of the inclination direction of the clamping screw 19 corresponds, so that in a twisting of the clamping screws 19 in the clamping direction, the terminal block 14 is pulled in total according to the inclination down and clamps the perforated plate 4 against the plate holder 3. Again, to improve the Cleaning possibility, the clamping screw 19 is releasably attached to the terminal block 14 ( FIGS. 6a to 6c ). The FIGS. 1 to 3 show that several Klemmleisteln 14 are provided in a side edges of the perforated plate 4 associated arrangement. Since in the embodiment shown two perforated plates 4 arranged side by side are present, the middle clamping bar 14 serves to load the two side edges of the left and right perforated plates 4. The presence of the middle clamping bar 14 also forces the formation of a receptacle 20 in the bulk material leveler 9 After removing the clamping screws 19 can be solved and the terminal strips 14 are moved in the gate 16 so that the guide pin 18 removed from the open end cam 17 and thus the terminal block 14 can be removed from the disc holder 3. The perforated plates 4 are thus freely accessible and can be removed and replaced by other perforated plates 4, then only the previously cleaned terminal strips 14 used again with their guide pins 18 in the cam 17 and must be pivoted to the perforated plates 4 for subsequent clamping by means of Clamping screw 19.
