Abstract

Die Erfindung betrifft eine Mischvorrichtung, deren Mischbehälter aus zwei schalenförmigen Behälterteilen besteht, wobei am Fahrgestell wenigstens ein Anschlagelement befestigt und an der Führungsgabel eine mit dem Anschlagelement in Spanneingriff bringbare Einzugsvorrichtung derart vorgesehen ist, daß das Fahrgestell mit dem ersten Behälterteil in die Ausgangsstellung des Mischbehälters einziehbar und dort arretierbar ist.The invention relates to a mixing device, the mixing container of which consists of two bowl-shaped container parts, at least one stop element being fastened to the chassis and a retraction device which can be brought into clamping engagement with the stop element being provided on the guide fork such that the chassis with the first container part can be retracted into the starting position of the mixing container and can be locked there.

Description

Die Erfindung bezieht sich auf eine Mischvorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a mixing device according to the preamble of claim 1.

Mischvorrichtungen der vorausgesetzten Art sind in ver­schiedenen Ausführungsformen aus der Praxis bekannt, wo­bei die Mischvorrichtung in ihrer Grundform beispiels­weise etwa gemäß DE-PS 21 10 074 oder DE-OS 34 26 159 ausgeführt sein kann. In der praxisgerechten Ausführung dieser bekannten Mischvorrichtungen wird der erste Be­hälterteil des Mischbehälters dann, wenn er nicht fest mit dem ersten Behälterteil verbunden ist, von einem Fahr­gestell getragen, wobei er dann lösbar darauf befestigt ist. Dieser erste Behälterteil kann dadurch beispiels­weise einerseits zwischen einer Befüllstation und den ortsfesten Teilen der Mischvorrichtung sowie andererseits zwischen diesem ortsfesten Teil der Mischvorrichtung und einer Verbraucherstation verfahren werden.Mixing devices of the presupposed type are known in practice in various embodiments, the basic shape of the mixing device can be designed, for example, according to DE-PS 21 10 074 or DE-OS 34 26 159. In the practical implementation of these known mixing devices, the first container part of the mixing container is carried by a chassis when it is not firmly connected to the first container part, and it is then releasably attached to it. This first container part can thereby be moved, for example, on the one hand between a filling station and the stationary parts of the mixing device and on the other hand between this stationary part of the mixing device and a consumer station.

Damit der mit einer Mischgutcharge befüllte erste Behäl­terteil in seine Ausgangsstellung unter den stationären zweiten Behälterteil gefahren und dort zur vertikalen Be­hälterachse ausgerichtet werden kann, ist an der ortsfe­sten Halterung der Mischvorrichtung eine Führungsgabel angeordnet, die das Fahrgestell in der Ausgangsstellung und Mischstellung des Mischbehälters aufnimmt.So that the first container part filled with a batch of mixed goods can be moved into its starting position under the stationary second container part and aligned there with the vertical container axis, a guide fork is arranged on the stationary holder of the mixing device, which holds the chassis in the starting position and the mixed position of the mixing container.

In der Praxis hat sich nun gezeigt, daß es trotz des Vor­sehens der Führungsgabel oft sehr schwierig ist, das Fahrgestell mitsamt dem gefüllten ersten Behälterteil in der gewünschten Weise in die Ausgangsstellung für den Mischbehälter einzufahren. Dieser Einfahrvorgang muß, insbesondere bei größeren Behältertypen, häufig wieder­holt werden, bis das Fahrgestell mit dem ersten Behälter­teil exakt in der Führungsgabel und damit unter dem stationären zweiten Behälterteil steht.In practice it has now been found that, despite the provision of the guide fork, it is often very difficult to move the chassis together with the filled first container part in the desired manner into the starting position for the mixing container. This run-in process must be repeated, especially with larger container types, until the chassis with the first container part is exactly in the guide fork and thus under the stationary second container part stands.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Mischvorrichtung der im Oberbegriff des Anspruches 1 vorausgesetzten Art zu schaffen, bei der durch relativ einfache bauliche Maßnahmen zuverlässig dafür gesorgt ist, daß der erste Behälterteil rasch und genau zum zweiten Behälterteil ausgerichtet in die Ausgangsstellung fahr­bar ist.The invention is therefore based on the object to provide a mixing device of the type required in the preamble of claim 1, in which relatively simple structural measures reliably ensure that the first container part can be moved quickly and precisely to the second container part in the starting position.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzei­chen des Anspruches 1 angegebenen Merkmale gelöst, wobei zweckmäßige Ausgestaltungen und Weiterbildungen der Erfindung Gegenstand der Unteransprüche sind.This object is achieved according to the invention by the features specified in the characterizing part of claim 1, expedient refinements and developments of the invention being the subject of the dependent claims.

Da bei der erfindungsgemäßen Ausführung der Mischvorrich­tung einerseits am Fahrgestell wenigstens ein Anschlag­element befestigt und andererseits an der Führungsgabel eine mit dem Anschlagelement in Eingriff bringbare Ein­zugsvorrichtung vorgesehen ist, kann auf äußerst zuver­lässige Weise dafür gesorgt werden, daß das Fahrgestell mitsamt dem davon getragenen ersten Behälterteil in die Ausgangsstellung des Mischbehälters eingezogen und arretiert wird, was aufgrund der Anordnung und Ausbildung der Führungsgabel sowie der passend zu dieser Führungs­gabel entsprechend der Ausgangsstellung des Mischbehälters vorgesehenen Ausführung des Fahrgestelles sehr rasch ge­schehen kann. Wenn bei dieser erfindungsgemäßen Ausführung das Fahrgestell in die Führungsgabel eingefahren wird, dann kommt die Einzugsvorrichtung mit dem Anschlagelement (vorzugsweise mit wenigstens zwei Anschlagelementen) des Fahrgestells in Spanneingriff, so daß durch die Aktivie­rung der Einzugsvorrichtung das Fahrgestell über das An­schlagelement ergriffen und sofort beim ersten Einfahren exakt in seine Endposition eingezogen und festgehalten wird. Diese Endposition des Fahrgestells in der Führungs­gabel stimmt dann mit der Stellung des ersten Behälter­ teiles überein, in der letzterer in der Ausgangsstellung des Mischbehälters genau unter dem zweiten Behälterteil ausgerichtet ist.Since in the embodiment of the mixing device according to the invention on the one hand at least one stop element is fastened and on the other hand a retraction device which can be brought into engagement with the stop element is provided on the guide fork, it can be ensured in an extremely reliable manner that the chassis together with the first container part carried by it Starting position of the mixing container is retracted and locked, which can happen very quickly due to the arrangement and design of the guide fork as well as the design of the chassis provided for this guide fork in accordance with the starting position of the mixing container. If in this embodiment according to the invention the chassis is retracted into the guide fork, then the retraction device comes into clamping engagement with the stop element (preferably with at least two stop elements) of the chassis, so that when the retraction device is activated, the chassis is gripped via the stop element and immediately upon first retraction is pulled in and held exactly in its final position. This end position of the chassis in the guide fork then matches the position of the first container Part coincides, in which the latter is aligned exactly below the second container part in the starting position of the mixing container.

Ein weiterer Vorteil dieser erfindungsgemäßen Ausführung der Mischvorrichtung ergibt sich durch die Tatsache, daß das Fahrgestell während des Mischvorganges sicher in der Führungsgabel gehalten und arretiert ist, wodurch nach Beendigung des Mischvorganges und Rückkehr des Mischbe­hälters in seine Ausgangsstellung ein exaktes Wiederauf­setzen des ersten Behälterteiles auf das Fahrgestell ge­währleistet ist.Another advantage of this embodiment of the mixing device according to the invention results from the fact that the chassis is securely held and locked in the guide fork during the mixing process, which means that after the mixing process has ended and the mixing tank has returned to its starting position, the first container part is put back on the chassis exactly is guaranteed.

  • Figure 1 is a side view of the mixing device when moving the first mixing container part into the starting position.
  • FIG. 2 shows the same side view as in FIG. 1, but with the container parts aligned vertically to one another (starting position of the mixing container) before they are coupled together, the chassis being drawn into the guide fork;

Die erfindungsgemäße Mischvorrichtung sei zunächst allge­mein anhand der Fig. 1 und 2 beschrieben, wobei vor allem die Darstellung in Fig. 2 den Gesamtaufbau bzw. die Ge­samtzusammenordnung der Mischvorrichtung erkennen läßt.The mixing device according to the invention will first be described generally with reference to FIGS. 1 and 2, the illustration in FIG. 2 in particular showing the overall structure or the overall arrangement of the mixing device.

Die Mischvorrichtung enthält einen Mischbehälter, der im wesentlichen aus einem verfahrbaren ersten Behälterteil 1 und einem stationären Behälterteil 2 besteht. Dabei ist der erste Behälterteil 1 mit einem Bodenauslauf 1a ver­sehen, und er wird von einem Fahrgestell getragen, das im veranschaulichten Ausführungsbeispiel in Form einer mit Rädern 3a versehenen Fahrpalette 3 ausgeführt ist und auf dem der erste Behälterteil 1 in an sich bekannter und daher nicht näher veranschaulichter Weise lösbar be­festigt ist, so daß er für eine Verbindung mit dem zwei­ten Behälterteil 2 von dieser Fahrpalette abgehoben wer­den kann.The mixing device contains a mixing container, which essentially consists of a movable first container part 1 and a stationary container part 2. The first container part 1 is provided with a floor outlet 1a, and it is carried by a chassis which, in the exemplary embodiment illustrated, is designed in the form of a driving pallet 3 provided with wheels 3a and on which the first container part 1 is known per se and therefore not closer illustrated manner is releasably attached so that it can be lifted from this range for connection to the second container part 2.

Der zweite Behälterteil 2 ist mit an sich bekannten Mischwerkzeugen 4 ausgestattet, die durch eine Motor­antriebseinheit drehend angetrieben werden können.The second container part 2 is equipped with mixing tools 4 known per se, which can be driven in rotation by a motor drive unit.

Die Mischvorrichtung enthält ferner eine ortsfeste Hal­terung 6, an deren oberen Ende der zweite Behälterteil 2 stationär derart gehaltert ist, daß er um 180° um eine horizontale Drehachse 7 zwischen einer Ausgangsstellung (etwa entsprechend Fig. 2), in der der zweite Behälter­tei 2 den Deckel des Mischbehälters bildet, und einer Mischstellung (in Fig. 2 strichpunktiert angedeutet), in der der zweite Behälterteil 2 den Boden des Mischbehäl­ters bildet, mit Hilfe eines Schwenkantriebes 8 geschwenkt werden kann.The mixing device also contains a stationary holder 6, at the upper end of which the second container part 2 is stationary so that it is 180 ° about a horizontal axis of rotation 7 between an initial position (approximately corresponding to FIG. 2) in which the second container part 2 Forms lid of the mixing container, and a mixing position (indicated by dash-dotted lines in FIG. 2), in which the second container part 2 forms the bottom of the mixing container, can be pivoted with the aid of a pivot drive 8.

An der ortsfesten Halterung 6 ist ferner eine Führungsga­bel 9 fest angeordnet, die für die Aufnahme des Fahrge­stelles (Fahrpalette 3) in der Ausgangsstellung (und auch in der Mischstellung) des Mischbehälters bestimmt ist.On the fixed bracket 6, a guide fork 9 is also fixed, which is intended for receiving the chassis (pallet 3) in the starting position (and also in the mixing position) of the mixing container.

Wie insbesondere in Fig. 3 in der Aufsicht auf die Fahr­palette 3 und die Führungsgabel 9 veranschaulicht ist, sind im vorliegenden Beispiel auf der Oberseite der Fahr­palette 3 zwei Anschlagelemente 10 symmetrisch zu beiden Seiten der vertikalen Mittelachse 1b des ersten Behälter­ teiles 1 sowie an dem der Führungsgabel 9 zugewandten Endabschnitt 3b der Fahrpalette 3 befestigt, vorzugs­weise angeschweißt. An der Führungsgabel 9 ist demgegen­über eine mit diesen Anschlagelementen 10 in Spannein­griff bringbare Einzugsvorrichtung derart vorgesehen, daß die Fahrpalette 3 mitsamt dem ersten Behälterteil 1 in die Ausgangsstellung des Mischbehälters gezogen und dort arretiert werden kann.As is particularly illustrated in FIG. 3 in the top view of the driving pallet 3 and the guide fork 9, in the present example on the top of the driving pallet 3, two stop elements 10 are symmetrical on both sides of the vertical central axis 1b of the first container part 1 and attached to the guide fork 9 facing end portion 3b of the pallet 3, preferably welded. On the other hand, a guide device which can be brought into clamping engagement with these stop elements 10 is provided on the guide fork 9 such that the driving pallet 3 together with the first container part 1 can be pulled into the starting position of the mixing container and locked there.

Die zuvor erwähnte Einzugsvorrichtung für die Fahrpalette 3 enthält auf jeder Seite der Führungsgabel 9 angebrachte, druckmittelbetriebene, vorzugsweise pneumatisch betätig­bare Zylinder-Kolben-Einheiten 11, wobei diese beiden Zylinder-Kolben-Einheiten 11 ebenfalls symmetrisch zu beiden Seiten der vertikalen Mittelachse 1b des ersten Behälterteiles 1 (und somit auch der dadurch bestimmten vertikalen Mischbehälterachse) angeordnet sind. Jede Zylinder-Kolben-Einheit 11 ist dabei für einen Spannein­griff einem Anschlagelement 10 der Fahrpalette 3 zuge­ordnet.The aforementioned pull-in device for the driving pallet 3 contains, on each side of the guide fork 9, pressure-medium-operated, preferably pneumatically actuated cylinder-piston units 11, these two cylinder-piston units 11 likewise being symmetrical on both sides of the vertical central axis 1b of the first container part 1 (and thus also the vertical mixing container axis determined thereby) are arranged. Each cylinder-piston unit 11 is assigned to a stop element 10 of the driving range 3 for a clamping engagement.

Im einzelnen ist jede Zylinder-Kolben-Einheit 11 mit ihrem einen Ende 11a schwenkbar über einen Schwenkzapfen 12 an der Führungsgabel 9 gehaltert und an ihrem anderen Ende 11b über das freie Ende ihrer Kolbenstange 13 gelen­kig ( Gelenkzapfen 14) mit einem Schwenkhebel 15 verbun­den, dessen eines Ende 15a über einen Schwenkzapfen 16 an der Führungsgabel 9 drehbar gelagert ist und dessen ande­res Ende 15b mit dem zugehörigen Anschlagelement 10 der Fahrpalette 3 in Spanneingriff gebracht werden kann.Specifically, each cylinder-piston unit 11 is pivotally supported at its one end 11a via a pivot pin 12 on the guide fork 9 and at its other end 11b via the free end of its piston rod 13 in an articulated manner (pivot pin 14) to a pivot lever 15, the one end 15a is rotatably mounted on the guide fork 9 via a pivot pin 16 and the other end 15b of which can be brought into clamping engagement with the associated stop element 10 of the driving range 3.

Wie in Fig. 3 gut zu erkennen ist, kann jedes Anschlag­element 10 in Form eines auf der Fahrpalette 3 aufge­schweißten Anschlagklotzes ausgebildet sein, und jeder Anschlagklotz kann dabei winkelförmig ausgeführt sein, so daß er eine Eingriffsausnehmung 10a für den zugehöri­gen Schwenkhebel 15 bzw. dessen Ende 15b aufweist.As can be clearly seen in FIG. 3, each stop element 10 can be designed in the form of a stop block welded onto the driving pallet 3, and each stop block can be angular so that it has an engagement recess 10a for the associated pivot lever 15 or its end 15b.

Während bei dieser bisher beschriebenen Ausführungsform zwei Anschlagelemente 10 mit diesen zugeordneten Zylinder­-Kolben-Einheiten 11 vorgesehen sind, kann bei einer be­sonders einfachen Ausführung, insbesondere kleineren Be­hältertypen, auch bereits ein einziges Anschlagelement - bei entsprechend symmetrischer Anbringung - ausreichend sein, und es versteht sich dabei ferner von selbst, daß die an der Führungsgabel vorgesehene Einzugsvorrichtung anstelle der druckmittelbetriebenen Zylinder-Kolben-Ein­heiten auch anderweitig betriebene Einzugsorgane, bei­spielsweise mechanische Hebel- oder Spindelantriebe oder Elektrokolben, enthalten kann.While in this embodiment described so far two stop elements 10 are provided with these associated cylinder-piston units 11, with a particularly simple design, in particular smaller container types, even a single stop element - with a correspondingly symmetrical attachment - can be sufficient, and it goes without saying it also goes without saying that the pull-in device provided on the guide fork may also contain pull-in members operated in other ways, for example mechanical lever or spindle drives or electric pistons, instead of the pressure-medium-operated cylinder-piston units.

Bei einer Mischvorrichtung der erläuterten Art soll der Mischvorgang vielfach auch teil- oder vollautomatisch gesteuert werden können, wozu diese Mischvorrichtung eine entsprechend angepaßte Steuereinrichtung enthält, die in Fig. 2 bei 17 angedeutet ist. Mit Hilfe dieser Steuereinrichtung 17 kann der Schwenk- und Mischbetrieb in gewünschter Weise eingeleitet und durchgeführt werden.In the case of a mixing device of the type described, the mixing process should in many cases also be able to be controlled partially or fully automatically, for which purpose this mixing device contains a correspondingly adapted control device, which is indicated at 17 in FIG. 2. With the help of this control device 17, the pivoting and mixing operation can be initiated and carried out in the desired manner.

Im Zusammenhang mit einer solchen Steuereinrichtung 17 kann es bei der Mischvorrichtung ferner besonders vor­teilhaft sein, wenn die Führungsgabel 9 einen Endschal­ter (Näherungsschalter) 18 trägt, der - wie durch die gestrichelte Linie 19 angedeutet - mit der Steuerein­richtung 17 steuerungsmäßig verbunden und durch die voll in die Führungsgabel 9 eingefahrene Fahrpalette 3, d. h. durch deren der Führungsgabel 9 zugewandten Endabschnitt 3b, betätigbar ist. Diese Ausbildung begünstigt besonders einen vollautomatischen Betrieb der Mischvorrichtung, d. h. wenn die in Richtung des Pfeiles 20 (Fig. 1 und 3) mitsamt dem ersten Behälterteil 1 in die Führungsgabel 9 eingefahrene Fahrpalette 3 voll eingezogen und arretiert ist, dann schaltet sie den Endschalter 18 in der Weise, daß dadurch der gesamte Mischvorgang - beginnend mit dem Verspannen der beiden Behälterteile 1 und 2 und dem Schwenken des Mischbehälters um die horizontale Achse 7 - eingeleitet und vollautomatisch durchgeführt werden kann.In connection with such a control device 17, it can also be particularly advantageous in the mixing device if the guide fork 9 carries a limit switch (proximity switch) 18 which - as indicated by the dashed line 19 - is connected to the control device 17 in terms of control and by means of the fully in the guide fork 9 retracted driving pallet 3, that is to say by its end section 3b facing the guide fork 9, can be actuated. This design particularly favors fully automatic operation of the mixing device, ie if the driving range 3 which has been moved into the guide fork 9 together with the first container part 1 in the direction of arrow 20 (FIGS. 1 and 3) is fully retracted and locked, then it switches the limit switch 18 in the way that thereby the entire mixing process - starting with the bracing of the two container parts 1 and 2 and the Swiveling the mixing container around the horizontal axis 7 - initiated and can be carried out fully automatically.
