• • the harmonic vibration.

shock vibration

The technological methods of shock vibration for shaping and compaction of mixtures, in particular concrete quantities in stiffer to very stiff consistency has been known for many years.

In this method, devices are mostly used in industrial production, which generate shock-like vibrations for the compression of the concrete amount by the generation of shock processes between machine components and act on the mixture to be processed. Known devices use vibration generating systems based on electric motor driven unbalanced shafts, such as in the Article "Increasing product quality through efficient compaction" by Berthold Schlecht and Alexander Neubauer, published in the journal "Betonwerk + Fertigteil-Technik", issue 9/2000, p. 44-52 , presented in detail.

A detailed description of the state of the art of the shock vibration method and the devices used therefor is given in US Pat DE 20301954 contain.

The advantage of the shock vibration with the very intense compaction effect are faced with a number of significant disadvantages. These exist

• • in the extremely high load of the machine technology and the associated high machine wear and the operating costs
• • in high environmental impact with vibrations and
• • in the extreme noise emission.

Harmonic vibration

method and devices for shaping and compacting mixtures, in particular concrete quantities in stiff to very stiff consistency by means of harmonious Vibration exposure has arisen recently, at least at the same conditions for product quality to reduce or avoid the disadvantages of shock vibration.

at The well-known technical solutions are harmonious Movement functions with the required acceleration amplitudes through produced various technical procedures.

there It can be assumed that the values of the accelerations in the Exciter frequency at least in the order of magnitude the accelerations in the excitation frequency with shock-like vibration have to come to comparable compaction effects too to reach.

A known technical solution for the shaping and compaction of mixtures in stiff to very stiff consistency consists in the application of one or more hydraulically operated Servo cylinder to the required high forces in one to generate harmonic time function

Hydraulic drive-based devices for concrete block production are in the above-mentioned article by Schlecht and Neubauer and in the Scriptures WO 01/47698 A1 described.

Another technical solution for the shaping and compression of mixtures is the generation of harmonic vibrations by means of rotating unbalanced shafts. This principle is also used for the forced excitation of the vibrating table in the shock vibration process. However, in the harmonic vibration method, the excitation forces must be significantly higher compared to the shock vibration method to comparable acceleration amplitudes for the sufficient shaping and compression of Ge to achieve quantity.

A known solution for this method is in DE 20301954 described. During vibration compacting with harmonic vibration, a stiff vibrating band consisting of the vibrating table, the base plate and the mold is temporarily produced by a form tension.

Another solution of shaping and compression of mixtures by means of harmonic vibration, developed by G. Becker, is in the journal "Betonwerk + Fertigteil-Technik", issue 10/2007 "Increasing Performance and Reducing Noise with Harmonic Vibration", p. 22-27 , described.

On an elastically mounted swinging table with those at the bottom attached unbalanced vibrators are base plate and mold with the amount of concrete to be compacted contained in the molding chambers. During the action of the harmonic vibrations will be the shape and the backing board with such force on the Swing table pressed that during this time no relative movements between these components of the vibration bandage can occur more. This force is by vertical movable spring assemblies applied during the Press vibration on the mold and on the opposite Spring side are temporarily fixed to the frame positioned. By their elastic properties ensure the oscillating movement of the Vibration Association. A ballast presses during the vibration is passive or active with its own vibration drives on the upper side of the concrete in the mold chambers.

Without reference to the realization of the harmonic vibration on large board machines are from the field of American block machines forms arranged directly on the form of imbalance pathogens such. In DE 689 04 376 T2 known.

• • der extrem hohen Maschinenbelastung,
• • der hohen Umweltbelastung mit Schwingungen und
• • der extremen Lärmemission.

All of the harmonic compression devices described herein significantly reduce the previously described disadvantages of shock vibration devices

• • the extremely high machine load,
• • the high environmental impact with vibrations and
• • the extreme noise emission.

Criticism of the state of the art

In spite of the visible advantages of the described technical solutions for the shaping and compression by means of harmonic Vibration these are also associated with significant disadvantages.

In the choice of a hydraulic drive medium is a great Disadvantage. Straight servo hydraulics require extreme purity of oil, which is in the environment of a concrete plant only can be maintained with high effort. Furthermore is the energy requirement of a hydraulic-based device much higher due to the relatively poor efficiency than conventional electromotive shock vibration devices. moreover are the initial cost of such a servo hydraulic system significantly higher than for an electromotive Drive.

When Another disadvantage is found in some of the solutions described, that in addition to the mixture to be compacted other components moved must be, which have a high mass due to the structure. A mass analysis shows that significantly more steel construction than too compressing mixture must be vibrated which requires correspondingly sized unbalanced shafts and reduces the efficiency.

Because of the necessary temporarily fixed connection of all components of the vibration system, consisting of vibration table with vibration exciter system, Base plate, shape and the mixture to be compacted is a Shaping required, the very large forces must apply relative movements between the vibrating components safe to prevent. The large clamping forces require correspondingly complex and fixed clamping assemblies, the even increase the swinging mass further and one subject to high wear.

in the Solution example of the production facility of G. Becker Be the applied here also clamping forces a relatively large force path through parts of the machine frame on the one hand, a correspondingly load-appropriate design requires and represents a high machine load.

task

• • eine deutliche Reduzierung der bewegten Massen und
• • eine Vereinfachung der Verspannung insbesondere hinsichtlich Größe der Verspannkraft.

The object of the invention is, while maintaining the method of shaping and compaction of mixtures, preferably concrete quantities in rigid and very stiff consistency for the production of concrete products and paving stones by means of the harmonic vibration action to develop a manufacturing facility, which is characterized by

• • a significant reduction of the moving masses and
• A simplification of the bracing, in particular with regard to the size of the bracing force.

The inventive task of reducing the moving masses is achieved in that the temporary vibratory structure is formed within the concrete paver so that the force path between the source of excitation forces - the vibration exciter system - and the amount of concrete to be compacted in the mold insert is reduced to the shortest possible extent by the vibration exciter system acts directly on the mold insert on the vibration frame and the excitation forces directly into the mold. This eliminates the previously required and due to its rigid design very massive swinging table.

For the production of concrete blocks and concrete products in different Dimensions is the mold insert as detachable from the vibrating frame Component formed. Depending on the one to be manufactured Product becomes the required mold insert in the vibration frame set and i. A. positively connected thereto.

The Swing capability of the molded insert with the vibration frame and the vibration exciter system attacking it is replaced by a elastic storage on vibration frame springs achieved at the same time also take over the vibration isolation relative to the machine frame.

To below, the shape and each form element by the known backing board closed, wherein in the inventive solution, the base plate by an elastic attachment to the bottom of the mold by means of spring elements the swinging motion of the mold follows and a secure closure ensures the molding chambers during the harmonic vibration.

To above, each mold chamber is temporarily during the harmonic vibration completed by one load plate each. All load plates are combined as a module and form the load group. It is counteracted by a lifting device pressed the surface of the concrete amount, taking a moving part of the load group with the movements of the form with the concrete amount by an elastic coupling between the moving and frame-fixed part follows on load springs and thus one Ensures closure of the mold chamber.

The attached to the vibration frame vibration exciter system is in mirror symmetry Construction to a vertical center plane through the vertical Mold center is formed and is dynamically preferred operated so that the mold with the amount of concrete to be compacted is applied with a directed vertical vibration. But also horizontal vibration components are possible.

The inventive task of simplifying the tension in particular in terms of size of the clamping force is characterized solved that it is omitted in the previous function.

Because of the direct introduction of force into the vibration frame with mold insert is a tension between unbalance exciter and mold insert, the for the demoulding in the clock cycle opens and closes not necessary anymore. For the possibility of Replacing the mold insert when changing products, there are joints as an interface between mold insert and vibration frame, through which to lead the forces. These must however only released with mold insert change and reconnected be what by conventional screw and / or clamp connections is performed.

The temporarily secure connection of the base plate with the Form during the harmonic vibration is replaced by a Bretthubeinrichtung with Bretthubzylinder, the underlay board from below against the mold insert moves achieved. Because of the much smaller swinging mass of the underlay board including proportionate batch of compound in proportion to the moving masses in previous solutions from the state The technology is much smaller for the temporary installation of the base plate on the mold required which are to be applied by the Bretthubzylinder or the.

While the harmonic vibration secure board springs the movement of the Underlay boards with the mold and its permanent attachment at the bottom of the mold.

To Completion of molding and compaction becomes the vibration action reset to zero, resulting in shutdown or power-free operation z. B. can be reached in a 4-wave arrangement. The demoulding takes place by a synchronous movement of the Bretthubzylinders and the lift-down cylinder down, the shape of their position maintains.

In a simple embodiment of the invention is the vibration exciter system from a pair of unbalance exciter shafts that are mirror-symmetrical on the vibration frame with respect to the vertical shape center plane are installed and in opposite directions with the same speed and mirror-symmetric phase relationship to the vertical shape center plane work. In this mode of operation are vertically directed harmonic oscillations stimulated. By a suitable design of the dynamic unbalance moments will be the forces required to produce the for the shaping and compression favorable vibration effects reached.

In a further embodiment of the invention, the vibration exciter system consists of egg nem pair mirror-symmetrically mounted and driven double or quadruple waves that both produce a directed harmonic vibration effect on the shape and allow adjustment of the effective resulting exciter force amplitude during vibration continuously between zero and a maximum by pairwise synchronous changing the phase angle between the corresponding unbalanced shafts , This feature allows, for example, a zero exciter power up the speed from zero to the operating speed. without swing path overshoots when passing through the rigid body natural frequencies. Furthermore, a continuous operation of this vibration exciter system is possible in which the resulting exciter force amplitude is set to zero by a phase angle adjustment during the clock change, without having to set the drive speed of the unbalanced shafts to zero. By dispensing with the ramp-up and ramp-down speed, short cycle times are possible.

By changing the phase position in the operating frequency can be as favorable for the compression determined exciter force amplitudes be set.

A comparable functionality of the vibration excitation is when using an adjustment exciter system accordingly DE 197 35 268 reached.

A Another embodiment of the invention consists in the application of a positively-driven vibration drive via hydraulic, pneumatic or Piezoelectric actuators that use the vibrating frame with mold insert as a single drive or in a mirror-symmetrical arrangement with respect the vertical shape center plane into vertical harmonic vibrations offset. Because of the lower excitation forces in comparison for harmonic vibration of the prior art are here physically smaller Components can be used as purchase units.

A Further development of the invention also uses vibration excitation on the base board. So have mold insert and board respectively himself about the excitation system, the harmonic oscillatory motion necessary is. The exciter systems are via a controller coordinated. So only small forces between mold insert and replace the stock board.

Description of the invention

The Invention will be closer by way of example with reference to the drawings explained.

In 1 shows the basic structure of a device according to the invention for shaping mixtures, in particular for the production of concrete blocks.

In a vibration frame ( 5 ) is a mold insert ( 4 ) and connected to this play and releasably. The connection between mold insert ( 4 ) and vibration frames ( 5 ) can only be released and restored if the product is changed and the associated change of mold is used.

On the vibration frame ( 5 ) are the vibration exciters ( 11 ) are fastened in a generally mirror-symmetrical arrangement to the mold center plane, in the simplest case an unbalance exciter pair in single-shaft arrangement (FIG. 11 ) enough.

The vibration frame ( 5 ) is the component that absorbs the vibrations from the vibration source - the vibration exciters ( 11 ) - for mold use ( 4 ) with the mixture contained therein ( 17 ) transmits. From the vibrational requirements, he ensures the rigidity of the vibrating body, consisting of vibration frame ( 5 ) with vibration exciters attached thereto ( 11 ), the mold insert ( 4 ) and base plate ( 7 ) and load ( 2 ).

The vibration frame thus fulfills the same function as the vibration table and the mold frame of a technical solution according to the prior art. Due to the short force path and the compact design, the moving mass of the solution according to the invention is advantageously significantly lower in comparison to known solutions such as in DE 20301954 , This is associated with a significant reduction of the excitation forces while achieving equal acceleration amplitudes for the shaping and compression of the batch.

The underlay board ( 7 ) after its transfer to the position shown with the Bretthubbaugruppe, consisting of Bretthubzylinder ( 10 ), Bretthub ( 8th ) and board springs ( 9 ) before vibration effect against the mold insert ( 4 ). The elastic connection between the backing board ( 7 ) and Bretthub ( 8th ) over the board springs ( 9 ) together with sufficient of the Bretthub cylinders ( 10 ) applied force the mobility of the backing board ( 7 ) during the vibration without it from the mold insert ( 4 ) takes off. It follows during the vibration impact the movements of the mold insert ( 4 ) and closes the mold chambers down.

The necessary contact forces for a permanent installation during the vibration are essentially dependent on the mass of the underlay board ( 7 ) and the acceleration amplitudes at the base board ( 7 ). Assuming equal vibration effects, ie acceleration amplitudes on the backing board ( 7 ) and the mold insert ( 4 ) as an interface to the mixture to be compacted ( 17 ), a further advantage of the invention is that the required clamping forces between vibration-inducing and shaping components - ie according to the invention between vibration frame ( 5 ) with mold insert ( 4 ), Vibration exciter ( 11 ) as well as underlay board ( 7 ) - because of the much lower mass of the backing board ( 7 ) Compared to the known masses of the components to be braced in the Trade journal "Betonwerk + Fertigteil-Technik", issue 10/2007, p. 22-27 or in DE 20301954 described solutions are much smaller. You can see through the shown Bretthubbaugruppe with the Bretthubzylindern ( 10 ) can be generated without problems.

The board springs ( 9 ) at the same time have the function of vibration isolation in relation to the frame-fixed environment.

In the individual mold chambers of the mold insert ( 4 ), the mixture to be compacted ( 17 ) filled. Then the ballast assembly consisting of lift-up cylinders ( 1 ) and load ( 2 ) until the load plates push on the batch surface. The loading springs ( 3 ) ensure the movement of the surcharge ( 2 ) during the vibration and the vibration isolation to the machine frame.

During demoulding, the vibration frame remains ( 5 ) with mold insert ( 4 ) in contrast to the prior art in its position, which is advantageous for vibration exciter ( 11 ) and stuffing car is.

Due to the fixed position of the vibration frame ( 5 ) with mold insert ( 4 ) eliminates the Formhubeinrichtung from the prior art, which had to lift during the demoulding relatively high masses.

The Shuttering takes place in the solution according to the invention through the Bretthub with smaller masses to be moved, with ballast movement and Bretthub are coordinated.

If required, it is also possible to dismantle by forming stroke, in which case the underlay board ( 7 ) can remain in its position.

2 shows design variants of the vibration frame ( 5 ) with attached vibration exciters and mold insert ( 4 ).

The Vibration exciter system can consist of rotating unbalance systems, these are mounted in pairs on the sides and synchronized z. B. with the help of an electronic control.

They are paired unbalanced wave systems with single shaft ( 11 ), with double shaft ( 12 ) and 4-fold wave ( 13 ) as well as with adjustment unbalance ( 14 ) conceivable. The vibration generation can also be done by means of dynamically operating hydraulic, pneumatic, electrical or piezoelectric actuators.

3 shows an exemplary solution of the connection between vibration frame ( 5 ) and mold insert ( 4 ). This backlash-free connection can be made mechanically by screwing or by means of a splined connection ( 16 ), whereby hydraulic actuators can also be used.

4 shows the device according to the invention in a structurally extended embodiment. Between Bretthub ( 8th ) and underlay board ( 7 ) is an auxiliary swing table ( 19 ). The auxiliary swing table ( 19 ) has a vibration system ( 20 ) that the coordinated movement of the underlay board ( 7 ) relative to the movement of the vibrating frame ( 5 ) with mold insert ( 4 ) serves. Via a controller ( 21 ), both movements are coordinated so that the base board ( 7 ) during vibration always at the bottom of the mold insert ( 4 ) is applied and at the same time the required pressure forces are minimized.

Advantages of the invention

The Invention has a number of advantages compared to the state the technology.

Due to the direct connection of the vibration exciter with the vibration frame ( 5 ) and the insert used therein ( 4 ) is a shortest possible path between the vibration source and the amount of concrete to be compacted ( 17 ) in the mold insert ( 4 ), taking into account a sufficient bending stiffness and the Possibility of change of shape achieved at product change. This is associated with a significant reduction of the moving masses. The lower masses that are to be put into vibration have the consequence that with the same values to be achieved of the motion variables for a sufficient shaping and compression lower excitation forces are required, which increases the efficiency of the device.

The technical solution of the tension was due to the lower required clamping forces designed much easier.

With the overall lower moving masses and the much lower Clamping forces can reach shorter cycle times be, because, for example, for hydraulic actuators smaller sizes are applicable with lower displacement, the same hydraulic volume flow drive through the travel paths faster.

The Advantages of noise reduction in the application of harmonic Vibration are already in the described solutions for State of the art become known. With the invention Solution is possible further reduction because With the reduction of the moving masses also the effective Radiating surface for the noise reduced.
