Description

The invention relates to a device according to the preamble of the main claim.

Such a device is known from DE-OS 14 59 367. It has a delivery point for on a bridge that can be driven under by a transport vehicle Cement and aggregates with an intermediate container. The intermediate container is not divided so that the cement and the aggregates already come into contact with one another in the container. In order to this container cannot keep its contents in stock for a long period of time, since sand and the like always is moisture-containing and premature this moisture in an undesirable way with the cement Reactions. A long stockpiling is not provided either, only an initial one should be used dosed amount of cement and aggregates can be poured in while the second is being provided. When one mixer after the other comes to fill at peak times, it brings Intermediate container does not save time, as it should take longer to fill than changing locations between a loaded and the following transport mixer. A second mixing device provided on the bridge for the delivery of precast concrete on a no longer mixing transport vehicle is arranged so that not even this point at the same time can be approached with the other intermediate container

is slidably mounted

5. Device according to one of claims 1 to 4, characterized in that the conveying device (15d- h) has buckets (7,7 ") which are used for the simultaneous transport of all components in chambers (7a, 7a", 76, 7b ", 7c 7c "), which are arranged corresponding to the chambers (10a, 10a ', 10a", 106,10 b', 106 ", 10c; 10c ', Wc") of the intermediate container (10) and are each provided with a dispensing opening .

10. Apparatus according to claim 2 and 3, characterized characterized in that at least two independently movable conveying devices (15) are provided in the same direction.

can. The device therefore only ever allows a single vehicle to be charged. The object of the invention is to provide a device of

to train named genus so that they have an even workload of the system and a rapid and economical delivery of concrete, especially at peak times, and that ready-mixed concrete in several places at the same time

^{5 (1} shear can be loaded.

According to the invention, the object is achieved according to the characterizing part of the main claim.

The device according to the invention makes it possible by loading a number of intermediate containers tern at the filling station an equal number of To deliver concrete mixers at the same time. The main advantage here is that all for the Batch required components pre-dosed independently of the call time and correspondingly long in stock can be held because they cannot react with one another in the subdivided intermediate containers. In this way, known peak times in particular can be prepared and mitigated.

It is already known (DE-OS 14 71 391) a container for the separate reception of cement and Subdivide aggregates. However, this container is for the transport of the substances mentioned to a Place of use, if necessary with there in front of

A mixing device, intended, not for loading of transport mixers directly at the filling location It is designed to be flexible and represents a complex combination two sacks, whereby the effort in production and operation only has the advantage that the contents of the two bags are coordinated and that there is no possibility of confusion are.

Furthermore, from DE-PS 15 84 394 a balance is known, the container has chambers in which Water, cement and aggregates are to be stored separately from one another. After completion of the weighing process the weighing container is opened and the components are simultaneously placed in a stationary mixer This device has the purpose of simplifying the weighing process, in particular a single scales for all components instead of several individual scales for aggregates, cement and use water. The subdivision of the weighing container should therefore just include further containers or Save scales with containers.

Also known from the German utility model 17 48 559 is a loading bucket for Mixing machine that is divided into two chambers. One of them is for the aggregates, one for cement certainly. The loading bucket is only for direct transport from a dosing device to the Mixer determined The division into chambers is only intended to prevent, in particular in the area of the In the bucket floor, reactions of the aggregates with the cement occur during this path lead to the fact that the contents of the bucket are not completely or only after additional external influence, such as knocking and the like, emptied. Long-term storage is not intended.

A conveyor is already known for loading two stationary mixing devices (German Utility model 7110 737) with an approximately Y-shaped conveyor track for two loading buckets. One way of the conveyor track goes from a metering device on which the loading buckets can be loaded alternately, and has a switch at the fork, each of which is different moving loading bucket is switched automatically. Thus, both starting and ending points are as well as the conveyor itself stationary. The conveyor cannot handle many Places to be admitted. If, as mentioned as an expansion option, more than two mixers are charged are to be, there is an additional conveyor track for each, possibly accessible via a switch set up.

In the device according to the invention, either one or more conveying devices are movable adjustable to a large number of intermediate containers serving for storage, i.e. mobile, or the intermediate containers can be moved to one or more end points of a stationary conveyor device can be brought up, or both the conveying device and the intermediate container used for storage portable.

The intermediate containers of the device according to the invention can be of simple and robust construction and have a considerable service life. As a further economic advantage, they enable a significantly better utilization of existing transport concrete mixers, since there are no or no significant waiting times at the filling station for them. The energy saving is also essential, since the entire batch can be filled into the transport concrete mixer from an intermediate container at once, thus avoiding long rotation times while stationary.
The intermediate containers can be arranged on stationary parking spaces and the conveying device can optionally be adjusted to all intermediate containers. This device can be adapted to existing systems in a particularly economical manner. It is just

ίο a support device at a wheelchair height for the Intermediate containers and movable conveyors are necessary.

A simple and space-saving embodiment of a device with stationary intermediate containers

! 5 provides that the intermediate container in such a way on a Frame are arranged in ring segment shape that the center of the ring coincides with a cradle and leading the conveyor device radially from the metering device to each intermediate container is adjustable This arrangement has the advantage that the conveyor device when changing from an intermediate container on the other hand only rotated, does not have to be adjusted. Your inclination can remain unchanged, likewise their length. Another major advantage of the ring segment arrangement is that each Intermediate container from the outside, i.e. the larger circumferential side, well from a transport concrete mixer can be approached.

In another embodiment of the device

JO according to the invention, the intermediate container can be arranged stationary in a straight frame and the Conveying device parallel to the frame like a bridge between the metering device and a running rail be slidably mounted in front of the parking spaces.

J5 The conveyor may have buckets that for the simultaneous transport of all components are divided into chambers that correspond to the chambers of the Intermediate containers are arranged accordingly and each provided with a dispensing opening. Every bucket thus conveys all components to the relevant intermediate container at the same time. The handover all components are also carried out at the same time.

In another embodiment of the device, the intermediate containers are designed to be movable and

• ti as a conveyor device at least one on the metering device Passing pair of rails provided. Each intermediate container can be connected to one or more Drive past the filling or dosing devices and pick up the individual components. At the same time offers

w this device the possibility of the intermediate container to approach one or more filling stations for the transport concrete mixer. It doesn't have to more all parking spaces for the intermediate containers for the transport concrete mixer will be accessible.

The track for the intermediate containers is advantageously at least partially two-lane with transition points educated. If the track does not form a closed ring for the intermediate containers, the at least partially two-lane training that

«J each full intermediate container for loading the Providing transport concrete mixers and feeding the empty intermediate containers to a filling point, or that they interfere with each other or stop in the course of the charging process.

t> 5 The conveyor devices for the buckets can be used for simultaneous conveying in both directions be at least partially formed in two lanes. With the second The charging station can be used as an alternative route.

Double the speed, as each empty bucket can move back while a new full bucket is on the way is. Two lanes, or provided with an escape point, can not only be stationary, but also parallel displaceable or radially movable conveying devices may be formed.

Essentially the same devices and objects are throughout all of the figures the same reference numerals.

In FIGS. 1 to 5, a star-shaped aggregate store 1 of different grain sizes, such as sand and gravel, with a removal opening 2 is shown in the right part of the drawing. A scraper 3 is assigned to it. In the area of the aggregate store 1, two cement silos 4 are also provided, of which a filling line 5 leads to a schematically illustrated metering device 6, one of several. A bucket 7, which is divided into a large chamber 7a and two smaller chambers Tb and 7c, ( Fi g. 3) can be filled there with cement, aggregates and water in certain quantities. Each of these components is in this case to Tc filled in one of the chambers 7a Each chamber 7a to 7c has a separate closure element. Opposite the aggregate store 1 is a frame 8 which, as FIG. 2 shows, is arranged in the form of a ring segment. The parking spaces 9 are designed so that the lower region of the intermediate container 10, in particular the floor area, protrudes freely downward. Furthermore, the frame 8 is designed in such a way that a transport concrete mixer 11 (FIG. 5) can approach each parking space 9 so far that it can take over the contents of the intermediate container 10 in its drum 12. In the illustration according to FIG. 5, this is done with the aid of a filler neck 13, which is arranged on the parking space 9 or on the intermediate container 10. The drum 12 of the concrete mixer 11 has catching members 13a, with which they the

to filler neck 13 catches when approaching and releases again after filling. The same arrangement also applies for the F i g. 1 to 4. The frame 8 also has a running rail 14. It runs on its top, and although adjacent in the area of its inner, the aggregate store 1 facing upper edge.

Each intermediate container 10 has a large chamber 10a and two smaller chambers 10b and 10c. Their spatial allocation corresponds to the allocation of the chambers 7a to Tc in the bucket 7 such that a bucket 7 located above the intermediate container 10 separates the contents of its individual chambers Ta to Tc can empty into the corresponding chambers 10a to 10c of the intermediate container 10. The large chamber 7a, 10a, the intermediate container 10 and the bucket 7 are for receiving aggregates such as gravel and sand, the smaller chambers Tb, Tc; XOb 10c, intended for the absorption of water or Zemeni.

A conveyor 15 for the bucket 7, here as

jo inclined elevator is formed with its lower end mounted below the metering device 6 by means of a pivot bearing 16. The top of the Conveyor device 15 is slidably supported on running rail 14 by means of a drive 17. He

J5 extends so far over the top of the frame 8 that the bucket 7 with its chambers 7a to Tc can be brought exactly over the three chambers 10a to 10c of the intermediate container 10. The conveyor device 15 can move in the direction of the double arrow A (FIG. 2)

ίο the pivot bearing 16 can be rotated, with the drive 17 runs on the running rail 14.

The described device according to FIGS. 1 and 2 works as follows: The conveyor device 15 is through Turning around the pivot bearing 16 brought into its position,

• »5 in which its upper area is above an empty intermediate container 10. The bucket 7 is charged with components that are matched to one another in terms of quantity at the dosing device 6, with one or more additives in the large chamber 7a, cement and water in the small chamber intended for this purpose Tb or Tc are filled. The conveying device 15 transports the bucket 7 upwards over the intermediate container 10 such that the chamber 7a of the bucket 7 is above the chamber 10a of the intermediate container 10, the chambers Tb and Tc above the chambers 106 and 10c (FIG. 1 shows the Bucket 7 once in the lowest and once in the top conveying position). The content of the bucket 7 is opened by opening the locking element, not shown.

M) te of the bucket chambers 7a to 7c in the corresponding Chambers 10a to 10c of the intermediate container 10 emptied. The empty bucket 7 is returned to the metering device 6 brought and reloaded with components. This process is repeated. Vis one for

fe5 a certain amount of concrete required Aggregates, cement and water in the corresponding chambers 10a to 10c of the intermediate container 10 are stored. This means that the chamber

walls separate components for transfer to a transport concrete mixer 11 ready. The conveyor 15 is now rotated so that its upper area is above another, empty intermediate container 10 is located, whereupon this intermediate container 10 is filled in the manner described. Repeat this as long as there are empty intermediate containers 10 on the frame 8. As soon as concrete at a construction site is required, a transport concrete mixer 11 drives in the in the manner shown in Figure 5 under a parking space 9 of the frame 8. While its drum 12 begins to rotate, the contents of the at this position 9 located intermediate container ίΟ through its bottom one after the other or at the same time through the filler neck 13 emptied into the drum 12. The rotation of the drum 12 immediately mixes the components. The transport concrete mixer 11 can be provided with a compulsory mixing tool 18. Already at At the end of the filling process for the drum 12, the mixing process is complete. Incidentally, the Drum contents also during transport to the construction site due to occasional or permanent rotation the drum 12 is kept in a mixed state. Further transport concrete mixers 11 can at any time, also at the same time, lower other parking spaces 9 with ge filled intermediate containers 10 drive and be filled. Each emptied intermediate container 10, under which there is no transport concrete mixer 11, can be returned immediately be filled in the manner described with the components for a concrete batch.

F i g. FIG. 3 shows a device that differs from that of FIG. 1 and 2 only differ in that two conveying devices 15a are present. Both are arranged on a single pivot bearing 16a in such a way that, like the single conveyor device 15 in FIG. 2 can be rotated back and forth in the direction of the double arrow A , whereby they are also supported on the running rail 14 with one drive in each case. The side view of the embodiment according to FIG. 3 corresponds to the embodiment F i g. 1, there actually being two buckets 7, one on each conveyor device 15. This device enables the same mode of operation as is used for the device according to FIG. 1 and 2 was described, only that two intermediate containers 10 can be filled at the same time. Each of the conveying devices 15a can be rotated over a currently empty intermediate container 10. The alternating filling of the bucket 7 can be controlled in a simple manner in that the bucket 7 of a conveying device 15a is always at the bottom when the other is at the top and vice versa.

F i g. 4 shows a further, in the side view F i g. 1 corresponding device. It differs from the device according to FIG. 2 only with regard to its conveying device 156, namely in that it has two lanes over part of the conveying path. One of the two tracks 156 'is for upward conveyance (arrow B), the other track 156 "for The downward conveyance (arrow Qdetermined. Otherwise, the conveying device 156 is designed analogously to the conveying device 15 in FIG. 2, ie movable about a pivot bearing 16, supported on the running rail 14 and thus movable to each empty intermediate container 10. FIG. 4 shows the two buckets 7 in their end positions, one at the bottom, one at the top, with solid lines. It also shows the two buckets 7 in dash-dotted lines during their encounter, one being conveyed up on track 156 'and the other down on track 150 " will.

The method of operation with this device is as described, only the filling speed is doubled for an intermediate container 10, since two buckets 7 can be constantly in motion. Depending on the training the conveying device 156 can also each have one of the two tracks 156 ′, 156 ″ for a specific bucket 7 be assigned, which can move up and down on it, so that the two lanes 156 'and 156 " form an alternative point.

ίο Fig.5 shows the schematic side view of a Apparatus which is essentially shown in FIGS. 2, 3 and 4 match, i.e. H. the in F i g. 5 labeled 15c The conveying device can be single or double lane, or two conveying devices 15c can be provided.

The difference lies in the shape of the frame 8c, which has a roof 19 over the parking spaces 9 in a different configuration of its supports. Furthermore, the device is equipped with tubs T without chambers, in which the tub T is tilted for emptying. For the sake of clarity, the tilting device is shown in FIG. 5, however, not shown. In this device, the components have to be conveyed individually and filled into the relevant chambers 10a to 10c of the intermediate container 10. Otherwise, FIG. 5 two work steps, the emptying of a bucket T with aggregates into the chamber 10a of an intermediate container 10 and the emptying of an intermediate container 10 into a transport concrete mixer 11.
In the F i g. 6, 7 and 8, the frame 8 with the parking spaces 9 and the running rail 14, as well as the intermediate containers 10, are designed as in the figures described above. On the right, however, there is a high collecting container 20 which has several chambers 20a for various aggregates, as well as cement and possibly water. The high-level collecting container 20 is loaded by means of an inclined conveyor 21, which is only indicated schematically in FIGS. It can be a conveyor device of a known type, for example a bucket conveyor or elevator. The inclined conveyor 21 feeds the components it is conveying to a displaceable transverse conveyor 22 which, in a known manner, optionally transports the material to be conveyed into one of the chambers 20a. A conveyor device 5d for buckets 7 is rotatably mounted about a vertical axis on a tower 23 carrying the high collecting container 20 by means of a pivot bearing 166. The conveying device \ 5d is supported by means of a drive 17 on the running rail 14, and is thus to be adjusted so that its end is located above an intermediate container 10.The mode of operation of the conveying device \ 5d is analogous to the mode of operation of the conveying device 15 according to FIG. 1 , whereby only the conveying direction of the full bucket 7 goes downwards and the return of the empty bucket 7 goes upwards Chamber of the bucket 7 is pulled The procedure is otherwise as described above, the chambers 10a to 10t / each intermediate container 10 are filled via the conveyor device \ 5d and emptied into a transport concrete mixer 11 if necessary. 6 shows the system with two conveyor devices 154 Fig .8 a conveyor device 15e, which is analogous to the conveyor device ng 156 in Fig. 4 two tracks 15e 'or. 15e ", so an alternative for two moving in opposite directions

Bucket 7 forms.

In the Fi g. 9 and 10 is a further exemplary embodiment of a device according to the invention with a star-shaped aggregate store 1 as in FIGS. 1 to 5 shown. A removal opening 2 and a scraper 3 are assigned to it. The device has a frame Sb which extends in a straight line and parallel to the front side of the aggregate store I. Accordingly, the parking spaces 9 of the frame Sb are arranged in alignment next to one another. Each parking space 9 carries an intermediate container iO 'with an elongated rectangular contour. Each intermediate container 10 'has a smaller chamber 0b' or 10c 'on its narrow sides and a large central chamber 10a' between the two. In the area of the front edge facing the aggregate store 1, a straight running rail 14a is arranged on the surface of the frame Sb. In front of the front of the aggregate store 1, a trench 24 runs parallel to the frame Sb. In the trench 24 there extends in the longitudinal direction a rail 25 on which buckets 7 "can be moved. The chambers 7a", 7b " and Tc" of the buckets 7 "are mutually exclusive The intermediate container 10 'is assigned analogously to the division of the chambers. In addition, there is a track 26 for a roller 27 on which a conveying device 15 / for the buckets 7 "is supported. The upper region of the conveying device 15 / is mounted displaceably with a carriage 17 on the running rail 14a. The conveyor device 15 / is displaced parallel to the frame Sb in the direction of the double arrow D so that its upper end area is located above an empty intermediate container 10 '. A bucket 7 "is first brought to the central metering device 6 and loaded, then moved to the lower end area of the conveyor device 15 / and then conveyed via the intermediate container 10 '. Each chamber 7a" to 7c "of the bucket 7" empties into the corresponding chamber 10a 'to 10c' of the intermediate container 10 '. If the chambers 10a 'to 10c' of the intermediate container 10 'are filled in this way, the conveying device 15 / can be moved to the next intermediate container 10'. «The transport concrete mixer 11 can be used in the form already shown in FIG. 5 shown way under the parking spaces 9 of the intermediate container 10 'and record their contents.

Fig. 10 shows a device with two conveyor devices directions 15 / in the f i g. 9 and 10 is not a cement silo shown. This, as well as a water connection, can also be located away from the central metering device 6 Another point of the trench 24 are, there also chambers of the bucket 7 ″ filled and attached to the Conveyors 15 / can be pushed.

They have an interior division into chambers 10a", 106 ", 10c" analogous to the containers 10 'in FIG Inclined floor 28 leads to an outlet opening 29 for the contents. Under the floor 28 is a running frame 30 attached The associated frames 8c extend substantially straight and are at least stretch- «> wise so wide that two pairs of rails 31, each for the bogies 30 of the intermediate container 10 "are provided, can run side by side. The two pairs of rails 31 are through inclined transitions 32 connected to one another, which can also be designed as switches. The racks 8c are otherwise in the top views according to Fi g. 12, 14 and 16 only indicated by the rail lines. In the embodiments according to FIGS. 11 to 14 are the Systems are provided with high collecting containers 20 on towers 23, the chamber 20a of which by means of an inclined conveyor 21 and a cross conveyor 22 are charged. This arrangement has already been related to the F i g. 6 to 8 described. In the embodiment of the device according to FIGS. 11 and 12, this has Frame 8c, as can be seen from FIG. 12, only in the area of the high collecting container 20 a second pair of rails 31, as well as a transition section on both sides this pair of rails 31. The frame 8c is arranged so close to the tower 23 that the short second Pair of rails 31 under the outlet of the high collecting container 20 passes. This device works in such a way that an empty intermediate container 10 "by appropriate shunting over a transition section 32 to the is brought under the Hochsammeibehäller 20 performing pair of rails 31. There will be his Chambers 10a ", 106", 10c "are filled with aggregates, cement and water. The full Intermediate container 10 ″ maneuvered back onto the continuous pair of rails 31 and parked The transport concrete mixer 11 can either have access to the frame 8c at each parking space 9 bring up the full intermediate container 10 "and connect your drum 12 to its outlet opening 29, or one or more easily accessible parking spaces 9 can be designated as filling stations and the filled intermediate container 10 ″ can be maneuvered to these parking spaces 9 if necessary.

The device according to FIGS. 13 and 14 has a frame 8c which carries two pairs of rails 31 over the entire length and which is arranged at a distance from the tower 23. A conveyor device i5g for buckets 7 ″ is fixedly attached to the tower 23, which leads from the metering device 6 of the high-quality container 20 to the pair of rails 31 closer to the tower 23 although each with the chamber to be filled 10a "to 10c" under the end of the conveyor device i5g. Fig. 13 shows two bucket 7 "in the respective end positions of the conveying device 15g.
