Definitions

  • the invention relates to a mixing device according to the preamble of claim 1.
  • the basic shape of the mixing device can be designed, for example, according to DE-C-21 10 074 or DE-A-34 26 159.
  • the first container part of the mixing container if it is not firmly connected to the first container part, is carried by a chassis, wherein 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.
  • 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.
  • 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.
  • 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 retracted and held exactly in its end position.
  • This end position of the chassis in the guide fork is then correct with the position of the first container part match, in which the latter is aligned exactly under the second container part in the starting position of the mixing container.
  • 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.
  • 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.
  • 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 off from this range for connection to the second container part 2.
  • 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.
  • 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 cover 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.
  • 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 cover 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.
  • 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.
  • two stop elements 10 are symmetrical on both sides of the vertical central axis 1b of the first container part 1 and on the end section 3b of the driving pallet 3 facing the guide fork 9, preferably welded on.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • this mixing device contains a correspondingly adapted control device, which is indicated at 17 in FIG. 2.
  • this control device 17 With the help of this control device 17, the pivoting and mixing operation can be initiated and carried out in the desired manner.
  • 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.
