In order to produce the form completely and evenly, it is still achieved by multi-lane pavers to fill, the filling truck will usually go OK.

Form, base plate, vibrating table and kind of a work cycle in two work areas The stamp plates are also phased together with two jrrieaelt one behind the other in the production direction, advantageously at the same time the main 20 lying layers are divided in such a way that the shaking process begins.

To be carried out by the successive types of work, which is seldom used, phases is the duration of a work cycle which otherwise makes the vibrating table too complicated. the Sum of all work phase times given. The result is therefore an imperfect filling The impact of a manufacturing machine is related or condensed, but mostly both. Through a with the acquisition and operating costs the compromise of these two fundamentally different for-production machines a decisive factor in the changes is little to be achieved. With the invention economy kit the machine. If the same appropriate procedures are used, however, two divided vibrator creation and operating costs are planned for the economic groups. For the filling process and that The ability of the machine in a linear relationship to the pre-vibration is a vibrator group with low output, directional vibration number, large directional vibration

Based on these considerations, it is advisable even with a wide and low imbalance.

3 4 find the mineral skeleton with cement paste. In Fig. 2 is a side view of the device according to Normal frequency required for compression Fig. 1 seen perpendicular to the manufacturing direction. The knocking effect is achieved by the high-frequency oscillation Fig. 1 shows a storage container 1 in addition to the i-iing far outweighed it. Production line of the device in which the fresh The invention further relates to a device 5 concrete is introduced from a concrete mixer, and to carry out the method for machine a filling carriage 2. The form 3 is in position I Forming artificial stone elements. In this before (Fig. 2) brought, and after their placement on the Direction, the storage containers are opposite to each other arranged next to the production line and consists of a steel grate (not visible in the drawing i their two filling carriages over the forms across the io bar), the form 3, the base board 6 and tertiary direction. the vibrator group 7 locked together. At the According to the invention it is proposed that the group filling the form 3 by repeatedly moving over it., Us base board, form and vibrator group under- with the filling carriage 2 sets the pre-vibrating approximately in the .. ■ to interlock and not over the vibrating last third of the filling process. Of course. A locking via the vibrating table is necessary, it is possible to have far more vibrating force on the opposite side and the theoretical production line can require a further storage container 1 to be required that the ratio of the vibrating and filling carriages 2 '(Fig . 1) to- ^ d to. As a result, in the case of idle vibration or useful vibration, production with facing concrete is even possible with output loss. As soon as the filling process is finished, 'rounds will hardly do justice. Instead of a »» the vibrator group 7 is detached from the support board 6, vibrating table according to known designs is set down at and slightly downwards, the embodiment according to the invention only having a bolt between the form 3 and the support! The interlane for the underlay board and the form in the case of the rest position board 6, however, remains. Form 3 and underlays. The significantly light boards 6 according to the invention are advanced with the known board feed into the right vibrator group hydraulically, mechanically or in position II (FIG. 2) until the form 3 and form 3 and 4 are electromagnetically possible with the base board and form Underlay board 6 is locked in the correct position under the '<chst rigidly, and this group will then occupy stamps 8. The fine alignment is carried out by means of a swivel buffer against the frame of the machine via the locking vertical gripper 9 of the molding machine, which is elastically supported Advantages. Only cylinder horizontally and vertically movable form vibrator group, base, mold and concrete swing. The guide 10 guides the second mold 11 from its upper position with concrete is therefore substantially back to position I, precisely above vibrator group 7, cheaper and enables a ratio of vibrating 35 A new platform 6 'is spread in a known manner with an empty or payload of about 10: 7, which is shown in position I inserted, form 11 on it, according to the theory of vibration engineering, the Be clay and compacted together with the vibrator group 7 by far the best. It is locked, and the filling process as well as the pre-jogging for structural reasons very easily possible, the second work cycle can begin
Stamp load for compression by simple 40 The form 3 is now in position II to optimally keep the width of the spring adjustment of the stamp plate for every concrete underlay board (6 or 6 ') in production filling. A compression conveying direction is shifted, the shock before the vibration is filled from position I and, if appropriate, and is locked together with the support board 6 with a short initial compression pressure in an appropriate size of the vibrator group 12. As soon as in position 1, the filling process of the second work cycle can begin via the ram by means of a hydraulic cylinder 45. The invention will be in position II of the ram shock and the arrangement allows a very large part of the pressing pressure to be transferred directly to the concrete by means of the ram 8 and the finished Rüttclcnergic. shake executed. After compaction is complete, however, the known designs transfer form 3 in position II by means of the form guiding system, with the majority of the vibrating energy being pulled up to the vibrating table from construction, whereby the punch 8 is slightly higher and the vibrating table is very heavy and the vibrating table is pulled as the form 3 The hori-support and only a fraction of it on the concrete zontalcn return of the form 3 by means of the form and therefore cause even with a very high centrifugal force guidance 10 from the position II to the position I and high energy expenditure only an insufficient amount of nothing . With the return of the Form J compaction of the concrete. The advance of the mold 11 begins with this, with the heads of the base stepping against the fixed struts. With which is pushed. As soon as the form 3 is in position 1 at> invention, the above-mentioned disadvantages are eliminated, whereby it is set and locked, in position 1 the two light, separate, in effect and execution 60 third work cycle begins and in position II the finished shaking different groups of vibrators to purchase and Be of the second work cycle, etc.
drive are cheaper than a single vibrator group according to patent claims:
well-known, much too heavy execution. ' An exemplary embodiment of the invention is shown in the first method for the machine molding of Drawing shown.
