Definitions

  • the invention relates to a mixing device according to the preamble of claim 1.
  • Mixing devices of the required type are known in practice in various embodiments; They are used, for example, to mix bulk components that can be filled into a portable mixing container part in a special loading station.
  • This mixing container part is transported under a stationary first mixing container part, aligned with respect to a stationary first mixing container part, lifted against the first mixing container part with the aid of a separate lifting device, which is generally provided in the bottom region of the mixing device, and with this first clamping device provided on the first mixing container part Mixing container part clamped to an entire mixing container, the drivable mixing tools are provided in the stationary first mixing container part.
  • These known mixing devices also contain a stationary frame on which the first mixing container part is pivotally mounted about a horizontal axis of rotation such that the mixing container formed from the two clamped mixing container parts between an initial position in which the first mixing container part forms the container lid and a mixing position, in which the first mixing container part forms the bottom of the mixing container, can be pivoted about 180 °.
  • the clamping device can be used to clamp the two together
  • Mixing container parts can be provided, for example, with cam-controlled clamping claws, which, when the aligned second mixing container part is raised against the stationary first mixing container part, reach under the opening flange of the transportable second mixing container part and clamp it against the opening flange of the first mixing container part, so that the two mixing container parts are also firmly clamped together are.
  • the clamping claws are driven and controlled with the aid of pressure-actuated lifting cylinders. For safety reasons, reliable monitoring of the clamp position is required during the entire mixed operation. Since this type of clamping claws as well as their actuation and control allow only relatively small tolerances, in the known mixing devices, relatively narrow tolerances, especially in the manufacture of the mixing container parts, must be observed in order to avoid malfunctions when the mixing container parts are clamped. In addition, problems can arise when the two mixing container parts are braced, in that the transportable second mixing container part is sometimes loaded with the mixing components on one side, as a result of which it is then moved under the stationary first mixing container part in a somewhat inclined or tilted position, which in turn aligns or Brings with it positioning problems.
  • the invention is therefore based on the object to provide a mixing device of the type required in the preamble of claim 1, the mixing container parts of which are relatively inexpensive to construct can be braced relatively easily and with sufficient accuracy, and a reliable connection of the two mixing container parts should always be ensured even during mixing operation.
  • the mixing device on the one hand at least two clamping lugs are fixedly distributed over the circumference of the transportable second mixing container part, while on the other hand the first mixing container part carries in its peripheral region at least two combined lifting-clamping elements adapted to the peripheral arrangement of the clamping lugs on the second mixing container part , which can be brought into engagement with one another in the sense of lifting the second mixing container part and, on the other hand, also in terms of tightening the two mixing container parts with the mentioned clamping approaches.
  • these combined lifting and tensioning elements simultaneously take over the lifting of the transportable second mixing container part against the stationary first mixing container part and the bracing of these two mixing container parts against one another to form the mixing container.
  • any suitable construction is conceivable for the formation of the lifting and tensioning elements, although they can generally also have both mechanical and pressure medium-operated stroke adjustments.
  • the lifting-tensioning elements have tensioning hooks that can be brought into engagement with the tensioning attachments of the second mixing container part, as well as mechanical stroke adjustments.
  • These mechanical stroke adjustments can be designed primarily in the form of threaded spindle drives, although, for example, those with a rack and pinion drive are also conceivable.
  • Formations with threaded spindle drives have the particular advantage that they are independent of these influences, for example in the event of a power failure or malfunctions in pneumatic or hydraulic systems, in that they are secured against loosening of the lifting and tensioning elements with great certainty by self-locking of the threaded spindles .
  • these guide devices are generally formed in the bottom region of the mixing device, for example in the form of separate guide forks, guide rails or the like provided with stops.
  • This type of guide device is therefore an extremely simply designed and attached element which, when the second mixing container part is positioned under the first mixing container part, ensures that the two mixing container parts are clamped together quickly and extremely reliably and which also represent a kind of securing this positioning during the entire state of tension.
  • the mixing device contains a mixing container 1, which is held overall in a stationary frame 2 and thereby about a horizontal axis of rotation 3 by about 180 ° from its initial position shown in FIG Fig. 2 shown mixing position and can be pivoted back, which will be discussed in more detail later.
  • the mixing container 1 consists of mixing container parts, of which the first mixing container part 1a is held stationary on the stationary frame 2 and is equipped with mixing tools which can be driven, for example, by a geared motor 4 and which are designed in a conventional manner can be and are therefore only indicated by dashed lines in Figure 1 at 5.
  • the second mixing container part 1b In its initial position, the second mixing container part 1b is provided with a lower floor outlet 6 and is completely open at its upper end surrounded by a connecting flange 7.
  • This second mixing container part 1b is designed to be transportable, so that it can be filled with mixing components in at least one loading station (not shown here) and can be emptied in a delivery station (also not shown) after the mixing has ended.
  • this second mixing container part For the transportable design of this second mixing container part, either a type of pallet truck (as indicated in the drawing) can be provided, on which this second mixing container part 1b with its bottom outlet 6 can be placed and moved, or this second mixing container part 1b can be at least partly used with a forklift, a traveling crane or the like. are transported between the corresponding stations and the actual mixing device, wherein it is fed in the direction of arrow 8 shown in FIG. 3 to the actual mixing device or is inserted into its stationary frame 2.
  • a type of pallet truck as indicated in the drawing
  • this second mixing container part 1b can be at least partly used with a forklift, a traveling crane or the like.
  • the two mixing container parts 1a, 1b are mutually clamped to the mixing container 1 with the aid of a clamping device to be explained in more detail (and in this starting position also detached from each other again), the second mixing container part 1b being relatively against the first mixing container part 1a something can be raised.
  • the stationary first mixing container part is held on the stationary frame 2, in particular on its horizontal axis of rotation 3, as a result of which it is in the Can be pivoted so that the mixing container 1 formed from the two braced together mixing container parts 1a, 1b between the starting position (Fig.1), in which the first mixing container part 1a forms the container lid, and the mixing position (Fig.2), in which this first mixing container part 1a forms the bottom of the mixing container 1b, can be pivoted about 180 °.
  • a structurally relatively simple, but extremely fast and very reliable acting clamping device for the mutual clamping of the two mixing container parts 1a and 1b results from the fact that at least two clamping lugs, preferably in the form of trunnions 9, are fixedly distributed over the circumference of the second mixing container part 1b and that the first mixing container part 1a carries in its circumferential area at least two of the circumferential distribution of the supporting pins 9, combined lifting-tensioning elements 10, which in the sense of lifting the second mixing container part 1b and bracing the two mixing container parts 1a, 1b against each other with the supporting pins 9 of the second mixing container part 1b can be brought into engagement.
  • the two trunnions (clamping lugs) 9 are - as can be seen particularly in FIG. 1 - attached to the upper, cylindrical peripheral wall 1b '' of the second mixing container part 1b, in the starting position of the mixing container 1 (FIG. 1) above the center of gravity of this second one Mixing container part, but with a sufficient distance below its upper end 1b 'are provided.
  • These two trunnions 9 are - as can also be seen in FIG. 1 - on the outer peripheral wall 1b '' of the second mixing container part 1b fastened, preferably welded, so that they project outward approximately horizontally from this peripheral wall 1b '' and that they are diametrically opposed to one another.
  • clamping lugs in this embodiment in the form of trunnions 9, can in principle be designed in any suitable form (for example as eyelets, hooks, or the like) in order to provide suitable stopping points for engaging and adapting to the stroke clamping Organs to form 10.
  • These combined lifting and tensioning elements 10 can also basically be designed in any meaningful way so that they can serve both for lifting the second mixing container part 1b against the first mixing container part 1a and for bracing these two mixing container parts against one another.
  • these lifting-tensioning elements 10 each have clamping hooks 11 which can be brought into engagement with the support pins 9 of the second mixing container part 1b, as well as mechanical stroke adjustments which, in the illustrated example, are designed in the form of threaded spindle drives 12 can.
  • These two threaded spindle drives 12 are in drive connection with a common drive motor 13 via suitable connecting devices 14, as a result of which the two threaded spindle drives 12 can be perfectly synchronized.
  • each stroke adjustment could also be provided with its own drive motor, also in this case if necessary, a synchronization could be ensured.
  • the transportable second mixing container part 1b when it is transported to be clamped with the first mixing container part 1a, can be aligned as quickly and sufficiently precisely as possible in the starting position with respect to the stationary first mixing container part 1a and largely coaxially with the vertical mixing container axis 1c a guide device for positioning this second mixing container part below the first mixing container part 1a is provided.
  • This guide device contains - viewed in relation to the feed direction (arrow 8) of the second mixing container part 1b - approximately in the rear circumferential area of the first mixing container part 1a at least two guide stop bars 15 which project downwards in the starting position of the mixing container 1 and which on the outer circumference of the - in the starting position - downward-facing open end edge 1a 'are firmly attached and are used for (stop) positioning of the second mixing container part 1b under the first mixing container part 1a. Furthermore, this guide device also includes at least one positioning bar 16 attached in the region of the front peripheral edge of the first mixing container part 1 a.
  • this positioning bar 16 can be moved downwards against the outer circumference, in particular against the upper end 1 ′ of the second mixing container part 1 b and can be locked or locked in this positioning position, so that the second mixing container part 1b is not only positioned and aligned very quickly and precisely in the starting position, but opposite in this aligned position the stationary first mixing container part 1a can also be locked.
  • This positioning bar 16 can be actuated in any suitable manner manually or with the aid of its own drive (for example pneumatic, hydraulic or electrical), this positioning bar 16 being able to be brought into its locking position, for example, by folding it down or swinging it down. This locking of the previously positioned second mixing container part 1b with respect to the first mixing container part 1a takes place before the second mixing container part 1b is lifted and clamped onto the first mixing container part 1a.
  • this mixing device If in this mixing device according to the invention a second mixing container part 1b filled with mixing components is transported, it can first be aligned very quickly and precisely with the guide stop bars 15 in the starting position of the mixing container 1 with respect to the downwardly opening first mixing container part 1a and coaxially to the mixing container axis 1c and then can be locked in this orientation using the positioning bar 16. At the same time, the support pins 9 of the second mixing container part 1b are also aligned with the tensioning hooks 11 of the lifting-tensioning elements 10, so that these tensioning hooks 11 come into engagement with the support pins 9.
  • the threaded spindle drives 12 of the lifting-clamping members 10 are then driven by the drive motor 13 in the sense of lifting and bracing the second mixing container part 1b against the first mixing container part 1a.
  • These positioning, locking as well as lifting and bracing measures can be carried out relatively quickly and extremely simply, but very reliably.
  • manufacturing tolerances in size and scope the mixing container parts or their connecting flanges largely irrelevant, since they can be easily compensated for by the threaded spindle drives or the other elements required for positioning and tensioning.
  • the clamping pressure with which the two mixing container parts 1a and 1b are clamped together to form the mixing container 1 is determined and controlled by the torque of the drive motor 13.
  • the self-locking of the threaded spindles of the threaded spindle drives 12 offers sufficient security against loosening the tension of the two mixing container parts 1a and 1b.
  • the second mixing container part 1b which is freshly filled with mixing components, is loaded somewhat on one side, since the supporting pins 9 fastened above the center of gravity of the second mixing container part 1b and the lifting-tensioning elements 10 acting thereon are potentially disruptive Tilting this second mixing container part can be avoided.
