Definitions

  • the invention relates to a system for reversibly holding a container in mixing position in a mixer, as well as a mixer comprising a such a holding system.
  • mixers that are suitable for mixing all types of products in liquid or viscous form contained in a container. In in particular, they can allow the production of emulsions from ingredients introduced into a container.
  • Such mixers must therefore allow the effective maintenance of a container in look at the mixing head of the mixer. Indeed, the mixing head rotating at a certain speed, it can cause the container to move if it is not maintained. In addition, the mixers must allow quick insertion and removal of containers under the mixing head whatever the size of said containers.
  • the invention aims to overcome these drawbacks by proposing a holding system reversible from a container in the mixing position in a mixer which allows quick and easy adjustment of the system depending on the size of the container.
  • this system does not require any new adjustment when exchanging a container by a container of the same size.
  • the system also allows ensure elastic clamping against the container without clamping force important.
  • the invention relates to a system of reversible holding of a container in the mixing position in a mixer, said system being intended to be fixed to a member of said mixer and comprising a first and a second arm which are mounted mobile in rotation relative around an axis between a position of insertion of the container between the two arms and a locked position in which the arms surround the container in exerting a peripheral clamping force, said system further comprising a reversible locking lever which is rotatably mounted about the axis, a elastic constraint in rotation which is integral on the one hand with the first arm and secondly the lever and a reversible locking device of the relative rotation of the second arm relative to the lever.
  • the invention relates to a mixer comprising a frame on which is mounted a mixing head, said mixer comprising in in addition to a reversible holding system for a container facing the head of mixture as described above.
  • Figure 1 is a schematic perspective representation of a mixer provided with a holding system according to the invention.
  • FIG 2 is a perspective view from above of the holding system according Figure 1.
  • Figure 3 is a perspective view from below of the holding system according to figure 1.
  • Figure 4 is a representation from below of the first arm of the holding according to Figures 2 and 3.
  • Figure 5 is a representation from below of the second arm of the holding according to Figures 2 and 3.
  • FIG. 6 is a representation from below of the locking lever of the holding system according to Figures 2 and 3.
  • Figures 7a, 7b, 7c are top views of different positions of the holding system according to FIGS. 2 and 3, respectively without container, with a container and when releasing the container.
  • the mixer 1 comprises a frame 2 provided with a column 3 on which an assembly is longitudinally sliding supporting a mixing head 4.
  • the mixing head 4 comprises a shaft rotated by a motor and provided at its end with a mixing, a propeller for example.
  • the base of the column 3 is provided with a base 5 on which the mixer 1.
  • a holding system 6 is arranged above the base 5.
  • This system is mounted on the column, for example by means of a ring 7 and clamping means (not shown) of the ring 7 on the column 3.
  • the clamping means can be loosened in order to adjust, by sliding the along column 3, the height of the holding system 6 as a function of dimensions of the container used.
  • the ring 7 is provided with a bore allowing the passage of a rod 8 of the support system.
  • the rod 8 is arranged in such a way that the holding 6 can hold a container facing the mixing head 4.
  • Des fixing means (not shown) of the rod 8 in the bore of the ring 7 are provided.
  • the holding system 6 comprises a first 9 and a second 10 arms.
  • the rod 8 is fixed under the second arm 10, as this can be seen in Figure 3, for example by means of screws.
  • the second arm 10 is therefore fixed relative to the frame 2 of the mixer 1 when the clamping means are tightened and that the rod 8 is fixed in the bore of the ring 7.
  • the first and second arms 9 and 10 are mounted in relative rotation around a substantially vertical axis 11 when the mixer rests on its base and have a curvilinear shape which can surround a container. So the first and second arm form a jaw when associated.
  • a locking lever 12 is also provided, mounted in rotation around axis 11 and interposed between the first and second arms 9 and 10.
  • a first 13 and a second 14 coaxial lugs are provided respectively on the face of the top 16 and on the bottom face 15 of the locking lever 12 in the vicinity from its periphery and near axis 11.
  • the first lug 13 is engaged in a groove 17 provided in the second arm in the vicinity of its periphery and near the axis 11.
  • the groove 17 is arranged to allow relative rotation of the lever with respect to the second arms on a defined stroke.
  • the groove 17 has a shape curvilinear, the center of which is axis 11, as shown in FIG. 5.
  • a reversible locking device comprising a thumb wheel 19 is mounted on the first lug 14 which is threaded. So we can block the movement of the lug 14 in the groove 17 by screwing the knob 19 and releasing this movement by unscrewing the thumbwheel 19. This has the effect of preventing or allowing rotation of the locking lever 12 relative to the second arm 10.
  • the second lug 14 is engaged in a groove 18 provided in the first arm 9 in the vicinity of its periphery and near the axis 11.
  • the groove 18 is arranged to allow the relative rotation of the lever 12 relative to the first arm 9 on a defined stroke.
  • the groove 18 has a shape curvilinear, the center of which is axis 11, as shown in FIG. 4.
  • the second lug 14 can also be threaded in order to be able to screw a fixing means, for example a nut (not shown), to hold the first arm 9 under the lever 12.
  • a fixing means for example a nut (not shown)
  • the screwing of the nut is provided to leave a clearance between the first arm 9 and the lever 12, thus the rotation of the lever relative on the first arm is possible.
  • An elastic rotation restraint device 20 is secured to the first arm 9 and the lever 12.
  • This device 20 comprises a first cubic member 21 integral with the underside of the first arm 9 and extending around the axis 11.
  • This first member comprises a housing 22 in which is mounted in rotation around the axis 11 a second cubic member 23 secured to the face from below the lever 15, as shown in FIG. 3.
  • the first and the second cubic members 21 and 23 are arranged so that the second cubic member 23 is offset by an angle substantially equal to 45 ° by relation to the first cubic organ 21 when no force is applied on the restraint 20.
  • Elastic means 24 are arranged in the housing 22 in the spaces created by the offset between the first and the second cubic organs 21 and 23. Thus, one can elastically constrain the relative rotation of the second member 23 in the housing 22.
  • the elastic means 24 can be formed from four strands of material elastomeric which are each arranged between an edge of the first member 21 and a face of the second member 23.
  • other restraint devices elastic may be provided, such as a return spring arranged between the first arm 9 and the sink 12 for example.
  • the first and second arms 9 and 10 include pads 25, 26 and 27 flexible arranged on their top face. These skates are intended for transmit the clamping force of the holding system 6 onto the container maintained in its mixing position.
  • the second arm 10 comprises two pads 25 and 26, mounted on pins 28 provided on the top face of the second arm near its end distant from axis 11, as shown in Figure 5.
  • These pads are formed from a strip of material elastomeric 29 which is wound taut around two pins 28. The strip of material protrudes radially inward from the arm.
  • the first arm 9 comprises a single shoe 27 similar to the shoes 25 and 26 and also mounted on two pins 28.
  • the two pins 28 are mounted on a rotating part 30 mounted on a lug 31 located on the top face of the first arm in the vicinity of its end remote from the axis 11, as shown in Figures 3 and 4.
  • the rotation of the part 30 allows to adapt the position of the shoe 27 to the shape of the container maintained. A better tightening of the container is thus assured.
  • the holding system 6 does not hold any container.
  • the second arm is fixed in rotation relative to the frame of the mixer. Without container and the wheel 19 being loose, the rotation of the first arm 9 relative to the second 10 is free and not elastic in the limits defined by grooves 17 and 18.
  • the rotation of lever 12 is also free within the limits defined by grooves 17 and 18.
  • the rotation of lever 12 relative to the first arm 9 is further limited by the restraining device elastic 20. This position is the insertion position of a container.
  • the first arm 9 is then brought back to the container by closing the jaw and by applying the pad 27 against the container, as shown in Figure 7b where a container 32 is held by the holding system 6.
  • the shoe 27 therefore forms against support on the container, and, when the lever is brought to the first arm, the rotation of the second cubic organ 23 in the housing 22 is elastically constrained and the rotation of the first arm by compared to the second becomes a rotation with an elastic reminder which tends to close the jaw. To accentuate and preserve this constraint, we tighten the wheel 19 on the lug 13 so as to make the lever 12 fixed relative to the second arm 10.
  • This provides a detachable and clutchable holding system 6 at will. by moving the lever 12 and tightening the thumb wheel 19.
  • the two arms of the holding system 6 exert a force of peripheral tightening around the container, keeping it firmly in place look of the mixing head 4 in a locked position.
  • the tightening device is however limited so as not to damage the container maintained. This limit is fixed by the groove 18 whose ends prevent to apply an elastic stress of too great intensity between the second cubic member 23 and the housing 22.
  • the vibrations caused by the rotation of the mixing head are partially absorbed by the elastic movement of the first arm 9. The support system is not therefore not disturbed by these vibrations and preserves its effectiveness during mixer operation.
  • the dimensions of the grooves 17 and 18 and those of the two arms 9 and 10 are by example chosen to allow the system to maintain containers having a capacity ranging from 0.1 L to approximately 20 L.
  • the holding system 6 can also include a safety sensor 33 which is intended to be connected to the control device of the mixer 1, as shown in FIG. 3.
  • This sensor 33 for example based on a angle measurement, is arranged to emit a signal prohibiting start-up of mixer 1 if the container 32 is not properly tightened in the mixer 1.
