Definitions
- the invention relates to a mixing device for preparing a ready-to-use compound consisting of at least one component which is to be mixed before use, in a cartridge with a tubular mixing rod, and to a working method with this mixing device and cartridge.
- Cartridges in particular two-component or multi-component cartridges with the features mentioned at the outset, are generally known in the prior art. Examples are on DE 198 28 351 A1, US 3,735,900 and
- Such cartridges are used to prepare and dispense one
- a base component in a storage and mixing space and, for example, a hardener in the tubular mixing rod are stored separately from the base component.
- a coupling arrangement is known from US 2006/0099028 A1, which can be used for the rapid connection and disconnection of an impeller shaft on a drive shaft.
- US 2011/0142536 A1 a quick connection assembly device for a mobile pump system or generator system is known.
- EP 1 994 977 A1 describes an automatic mixer for injecting and mixing an accelerating agent into a one containing a starting agent Known cartridge with filler, the accelerating means being contained in a hollow rod equipped with an injection and mixing head.
- a device for transmitting a reciprocating movement of a drive element to a stirring blade in a conditioning container in which the rotary movement is achieved by a helical rotation of a flat profile in a corresponding guide.
- the mixing device described at the outset is known from DE 20 2005 005 150 U1.
- the cartridge receptacle is designed such that the cartridge with its cylindrical storage and mixing space in a corresponding cylindrical receptacle with the mixing rod first in this head
- Cartridge holder is used, with a small edge at the end of the cartridge down from the mixing rod rests on a circumferential seat. Then the cartridge is firmly clamped with this small edge in the cartridge holder by means of a clamping piece via a bayonet catch.
- a clamping piece is provided with a pneumatic cylinder, which loads a pressure stamp on the compensating piston of the storage and mixing space of the cartridge.
- the object of the invention is therefore to simplify the insertion of the cartridge, starting from a mixing device according to DE 20 2005 005 150 LH, in particular to be able to operate them fully automatically.
- a mixing device according to DE 20 2005 005 150 LH
- the insertion and ejection of a cartridge to be mixed or a ready-mixed cartridge with automated handling means (robots) should be made possible.
- the holder for the coupling element of the mixing rod has at least two, preferably three clamping arms, which are designed so that the plate-shaped coupling element can be reclamped in order to be able to transmit torque to the mixing rod, simplifies the plate-shaped coupling element and thus the rotary drive of the mixing rod in such a way that simple manual handling or using robots is possible.
- the preferred three clamping arms span the plate-shaped coupling element so that a
- Torque can be transferred to the mixing rod.
- the tensioning arms are designed to be able to be wrapped around the plate-shaped coupling element about pivot axes arranged tangentially to the axis of rotation oriented coaxially to the mixing rod, a high holding force on the plate-shaped coupling element and thus reliable torque transmission can be ensured.
- the swivel axes for the tensioning arms can also be oriented slightly adjusted to the tangential direction to the axis of rotation, so that a secure clamping of the plate-shaped coupling element for torque transmission is still possible. If the clamping arms can be actuated with a second pneumatic cylinder, the clamping forces can be generated pneumatically.
- a second proximity sensor is arranged on the holder for the coupling element of the mixing rod, which sensor can detect the approach of the coupling element of a cartridge and can trigger the clamping of the plate-shaped coupling element.
- Clamping the cartridge in the mixing device is simplified and can be triggered by power, for example pneumatically.
- the clamping device has two jaw tongs which can be pivoted about a joint and have receptacles for the bottle neck-like section
- Cartridge are laterally fed to the clamping device without critical handling of the elongated cartridge with the mixing rod having to be carried out from one end.
- the cartridge can, for example, be gripped by a robot on the cylindrical storage and mixing space and radially to the axis of the joint with its longitudinal axis between the jaw tongs
- the jaw tongs preferably have approximately semi-cylindrical receptacles for the bottle neck-like section.
- the receptacles can also be prismatic or polygonal in order to be able to securely grip the bottle neck-like section of the cartridge.
- a first proximity sensor is arranged on the clamping means, which can detect the approach of a cartridge and trigger the clamping of the cartridge, the clamping of the cartridges can be automated with a corresponding supply of the cartridge.
- At least one component is accommodated in the storage and mixing space and the other component is accommodated in the tubular mixing rod, an insertion rod insertable into the tubular mixing rod, an insertion rod holder for holding the insertion rod and an insertion rod holder
- Fig. 1 shows a mixer with a cartridge not yet clamped in
- Fig. 4 in a partially sectioned representation of a front view of the
- FIG. 5a in an enlarged detail view.
- FIG. 1 shows a side view of a mixing device for preparing an operational sealing compound or adhesive compound.
- a cartridge 5 is positioned in the mixer, but not yet braced.
- the cartridge 5 has a storage and mixing space 51 with a compensating piston 52 (see FIG. 4), in which a first component (base component B) of the mass to be prepared is received.
- base component B base component of the mass to be prepared
- the cartridge 5 has a bottle-neck-like section 53 at its downward-pointing end, in which a tubular mixing rod 6 is rotatably and laterally displaceably guided.
- the tubular mixing rod 6 has a mixing head 61 at its end oriented in the storage and mixing space 51, which ensures that when rotating the mixing rod 6 in the storage and mixing space 51st
- a plate-shaped coupling element 62 is provided at the outward end of the tubular mixing rod 6.
- the other component for example a hardener H, is accommodated in the tubular mixing rod 6.
- the mixing device has a cartridge holder 1 for inserting the cartridge 5 to be prepared.
- the cartridge receptacle 1 has a lower receptacle 11, which has a clamping means 17 with which the cartridge 5 can be clamped on the bottle neck-like section 53.
- the mixer is shown with the clamping means 17 still open.
- the clamping means 17 has two jaw tongs 171, 172 which can be pivoted relative to one another about a joint 173.
- Semi-cylindrical receptacles 174 are provided in the first clamping jaw 171 and the second clamping jaw 172, so that the bottle neck-like section 53 of the cartridge 5 is securely from the
- Clamping means 17 can be clamped and held.
- a first pneumatic cylinder 18 is provided, which in the exemplary embodiment shown (see in particular FIG. 2) can adjust the second clamping jaw 172 about the joint 173 relative to the first clamping jaw 171.
- a first proximity sensor 19 is provided on the clamping means 17. This recognizes the insertion of the bottle neck-like section 53 of the cartridge 5 into the clamping means 17, as shown in FIGS. 1, 2 and 3 and 3a, and closes the first pneumatic cylinder 18 for clamping the cartridge 5 with compressed air, that is the clamping device 17.
- the cartridge receptacle 1 has an upper element 12, on which a counter-pressure cylinder 13 with an associated counter-pressure plate 14 is provided.
- This upper element 12 of the cartridge holder 1 lies just above the cartridge 5 to be inserted, so that after the insertion of the Cartridge 5 can be activated in the mixing device of the counter-pressure cylinder 13 and can load its counter-pressure plate 14 onto the compensating piston 52 in the cartridge 5.
- switching cams 15 are provided on the upper element 12 of the cartridge receptacle in order to match the lifting movement of the mixing rod for complete mixing of the mass taken up in the cartridge 5 in the supply and mixing chamber 51 through the mixing head 61 of the tubular mixing rod 6 to the respective cartridge size used ,
- a stationary holder 2 for the plate-shaped coupling element 62 of the mixing rod 6 is provided on the mixing unit, on which the mixing rod 6 is rotatably but fixedly received in the longitudinal direction.
- three clamping arms 21 are provided on the holder 2, which are oriented about pivot axes 22 which are tangential to the longitudinal axis of the cartridge 5 or the axis of rotation of the device. The three clamping arms 21 are over a second one
- Pneumatic cylinder 23 can be pivoted about these pivot axes 22 in a power-operated manner.
- a second proximity sensor 24 is provided on the holder 2, which activates the second pneumatic cylinder 23 for clamping the plate-shaped coupling element 62 by the clamping arms 21 when the plate-shaped coupling element 62 of the tubular mixing rod 6 approaches.
- Cartridge holder 1 with the cartridge 5 accommodated therein and thus the tubular mixing rod 6 projecting downward thereon (see FIG. 5 and in detail FIG. 5a).
- an insertion rod 31 held in an insertion rod receptacle 3 is inserted from below (below the holder 2) into the tubular mixing rod 6 by means of an insertion cylinder, not shown, and thus inserted there in a sealed section 63 of the tubular mixing rod 6 received component, for example the hardener H, injected into the storage and mixing space 51.
- the insertion rod 31 of the insertion rod receptacle 3 is withdrawn again after the other component H has been introduced.
- Counter pressure plate 14 balanced. Volume changes during the mixing process are also compensated for by the evenly loading counter-pressure cylinder 13.
- the mixing process is now pneumatically actuated via a mixing stroke cylinder 16 and rotary drive of the holder 2 by means of, for example, pneumatic drive means 4.
- the switching cams 15 also effect associated
- Bracket 2 transmits the rotary movement to the mixing rod 6 and thus the mixing head 61.
- the clamping arms 21 are opened by releasing the second pneumatic cylinder 23 so that the plate-shaped coupling element 62 of the mixing rod 6 is exposed and the upper element 12 of the cartridge receptacle 1 with its counter-pressure cylinder 13 and counter-pressure plate 14 is lifted out of the cartridge 5.
- the clamping means 17 is then opened as soon as the cartridge 5 is gripped, for example, by a robot arm. Now the robot can be used prepared sealant or adhesive in the cartridge 5 for
- Clamping jaw 172 enables a safe and easy-to-use clamping possibility for the cartridge 5 on the bottle neck-like section 51. Robots can thus also handle the cartridges, namely feeding the cartridge to the mixing device and removing cartridges that have already been prepared from the mixing device.
- the holder 2 provided with clamping arms 21 also makes it possible to automate the transmission and clamping of the mixing rod 6 by means of the plate-shaped coupling element 62.
- sealing compounds or adhesive compounds composed of at least two components which are accommodated in corresponding cartridges can thus be mixed reliably and with consistent quality and thus be prepared for use, the supply and removal of the cartridges being highly automated and for example carried out by robots.
