Device for the production of preferably several protruding elements, especially climbing elements such as crampons. Stirrups Or the like., provided concrete parts, e.g. manhole rings, manhole necks or the like.

The invention relates to an apparatus for producing with preferably several protruding elements, in particular climbing elements such as crampons, stirrups or the like., Provided Concrete parts, e.g. manhole rings, manhole necks or the like, according to the preamble of claim 1.

A known molding device of this type (DE-PS 31 10 165) has has proven itself well. It enables an automatic production process, which, however, is repeated several times for the purpose of performing manual work is interrupted. An interruption occurs after the end of the work cycle, in dsm a concrete part is completed and with the ejection plate and the lower sleeve for underfloor arrangement the device is ejected at the level of the mandrel lower edge. Then the finished concrete part is on the Lower sleeve resting, to be transported away. There is also a new one Place the lower sleeve on the ejection plate. In addition, the insertion of the individual protruding elements, especially riser elements, to be done by hand. For manhole rings with a construction height of 500 mm or for cones where only two risers are to be provided

the riser elements are inserted into the mold cores by hand from above. As a rule, the operator has to be on the ejector plate in order to insert the lifting elements kneel. If four climbing elements are set in concrete, they can only be inserted from above with great difficulty. Much more In the case of underfloor machines, it is then necessary for the operator to take a flight of stairs into the pit of the machine climbs down and then inserts the riser elements by hand into the mold segment of the mold core. This screamed These methods are obviously very cumbersome. they are also extremely physically demanding for the operator. These manual operations also have a great effect has a negative effect on the cycle time. Due to these manual activities, the automatic production process is very large influenceable times. In addition, the automatic Sequence can also be interrupted.

The invention is based on the object of providing a device of the type defined in the preamble of claim 1 create, which provides a remedy here and the operator from the manual introduction of the climbing elements with all disadvantages resulting therefrom relieved.

In the case of a device, the task is the one described in the preamble of Claim 1 defined genus according to the invention solved by the features in the characterizing part of claim 1.

By means of such an automatically working element inserting device, the protruding EIe elements, especially climbing elements, automatically into the form segment of the mold core are inserted in the underfloor area, while in the freely accessible area of the device the operator removes the finished concrete part at the end of the cycle time and the other manual urgent preparatory work for the implementation of the

most work cycle meets, especially when manufacturing Insert the next sub-socket. This reduces the cycle time of the device by the amount which would otherwise have made the manual introduction of the individual elements, in particular climbing elements, necessary. It is also advantageous that the operator of this cumbersome, extremely strenuous manual work is relieved. In addition, she otherwise fails, the corresponding manual activities given Bs controllability of the time by the operator.

This ensures that the protruding elements, in particular riser elements, are fed in at the same time as the The previously manufactured concrete part is transported away. This has the advantage that it reduces the cycle time of the machine ne both when manufacturing concrete parts without introducing protruding elements, especially riser elements, as well as in the manufacture of concrete parts with such elements is equally short. The time that was previously required for the manual insertion of the protruding elements was seen falls away. Because of the temporal overlap of the automatic feed and introduction of the protruding Elements, in particular climbing elements, the cycle time within which a concrete part is to be manufactured is shortened by this time segment. This increases the effectiveness of the

Process and also the machine used for it increased. The number of pieces to be produced per unit of time is elevated. At the same time, the automatic process produces reproducible results that are free from personal influence during manual handling. 30th

Further details and advantages emerge from claims 2- 5. It goes without saying that the gripping device Can be designed so that either only one element, in particular Steigelemt, or several Elements can be handled simultaneously from it. Each gripping device can have at least its own magazine be assigned. Another advantageous embodiment results from claim 6 .. Are advantageous fsrnsr dis embodiments It. Claims 7 and S Each holder can be assigned its own magazine. Instead, it can also be an advantage if a single magazine is assigned to two appropriately aligned holders and the gripping device is controlled accordingly when removing from the magazine.

Another advantageous embodiment results from claims 9 and 10 · This ensures that in this way not only commonly used as "crampons" designated climbing elements, but also stirrups are automatically fed. Stirrups usually exist made of light metal, e.g. aluminum. Because of their low weight, there is a risk that after introduction into the Recordings of the core segment by means of an ejector device and moving them back Slipping stirrups. This is countered by the fact that the stirrup clamps by means of the Gripper these are only released when the

Clamping devices of the core segment were activated 30

and hold the inserted stirrups. The latter can be found in the area of the anchoring ends, which are later in the Sitting in concrete, gripping, crampons can also be handled in the same way. By training as a

Gripper, the element insertion device is simpler, lighter and more cost-effective. You only need one imple mentation form for both types of climbing elements described.

Further advantageous measures emerge from claims 11 and 12. The features in claim it is guaranteed that the individual parts mentioned in the manufacture of concrete parts with different Nominal widths can be adjusted in terms of the angle, also if, for example, any protruding elements, especially riser elements, are not radially with respect to the central axis of the mold core, but aligned and introduced parallel to one another should be.

Another advantageous embodiment results from claim 14 and claims 15 and 16. Thereafter has each magazine has its own element guide device. This then forms when the element insert device is in its inserted position, a connection between the magazine on the one hand and the molding device on the other hand, wherein in the element guide device those that abut one another there Elements are advanced by at least one element length when the gripping device is activated. the Gripping device fulfills two tasks in one. On the one hand it fulfills the task of removing the element located at the bottom of the magazine stack, the element from the magazine stack is pulled out and moved into the element guide device. The gripping device is fulfilled by the latter also the task of advancing the elements within the element guide device by one element length, in such a way that at the front end there is an element through the discharge opening of the guide device

Due to the features in claim 17, one can see into the element guide device from the outside. This is therefore easy to monitor and, for example, offers cleaning in the event of a fault

Another advantageous embodiment results from claims 26 and 27. This element insertion device is even simpler. It is particularly suitable for a single-barrel arrangement in which several elements, for example Stirrups are to be placed one below the other. This element insertion device is particularly simple, inexpensive and space-saving.

Further advantageous measures emerge from claims 28 and 23. This embodiment provides with regard to Material costs and space requirements represent the lightest, smallest and cheapest solution. Depending on the individual case can do this despite the larger number of control functions and more frequent refilling of the Magazines predominate and make the difference.

Further advantageous measures emerge from claims 30-35. This form of the gripping device is Functionally reliable to a high degree, at the same time extraordinarily space-saving, simple and cheap.

Further details and advantages emerge from the following description.

Avoidance of unnecessary repetitions is expressly referred to. The same also applies to the mode of operation and the process sequence during shaping.

Part of the molding device is a mold core 15, which is designed in this way is that during the shaping of the concrete part 12 in this from the inside at the same time preferably several protruding elements of any kind, in the present example a total of four crampons 23-26, set in concrete can be. The term "-» crampons "used here includes all possible forms and designs of such elements that have the function of steps and walking enable a shaft composed of such concrete parts 12. The term crampon covers the so-called normal crampons and also heavier and larger safety crampons, e.g. each made of cast, as well as the climbing elements conventionally referred to as stirrups. Also in this respect reference is made to DE-PS 31 10 185.

The mold core 15 is approximately hat-shaped. It is hollow inside and attached to a central vibrator 14 so that it can be replaced. This ilitzt on a base plate 16. In the interior of the mold core 15 contains an example welded plate 17 is fitted with d _B r _it on the Zentralrüttler 14 and fixed. The plate 17 is, for example, approximately three quarters of a circle. The mold core 15 is round here, for example, but this is not mandatory. It has a circular cover 1Θ and a cylindrical core wall 19 leading down to the base plate 16.

The mold device also includes an outer mold jacket 22 and a lower sleeve 27 and an upper sleeve 40, the

are known.

The mold core Ib has a tin building device 2y - with their help during the shaping process one crampon, preferably all four crampons at the same time 23-26 or 23a-26a, can be concreted from the inside into the concrete part 12 to be formed. The installation device 29 has a core segment 30, which here consists of a cover section 31 and a wall section 32 is formed. The cover section 31 is slightly larger as a cover-side recess 28, which in the geffiSS state Fig. 2 of the cover section 31 sn the drsi stws sin U forming sides is sealingly overlapped. The recess The remaining part of the cover 18 containing 2Θ is attached to the core wall 19, in particular welded thereto or instead integrally therewith, whereby this remaining part of the mold core 15 solidifies and against deformation in the area of the cover 18, in particular the core wall 19 is stiffened.

The wall section 32 of the core segment 30 has the shape a portion of the cylinder wall. The cylindrical core wall 19 is corresponding to the wall section 32 with a cutout 34 of the same shape is provided which, in side view according to FIG. 1, is essentially approximately U-shape and extends from top to bottom. In a side view or section (FIG. 2), the core segment 30 is approximately Angular shape. It forms an independent element with respect to the remaining part of the mold core 15, together with the cover section 31, which is at the upper end of the wall section 32 is welded on. The core segment 30 is in relation to the mold core 15 from its shaping contour (Fig. 1-4) out in the direction of arrow 33 horizontally inside in a release position according to FIG. 5 and in the opposite direction to arrow 33 back to that shown in FIGS. 1-4 Movable closed position.

The underfloor machine 10 described according to the first embodiment in FIG Fig. 1-5 is within the working area 11 with -a working automatically

² ^ element insertion device 50, which is integrated into the underfloor machine 10. It is placed on the carrier and shown in Figs. 3 and 4 alone. It is at least substantially at the same level as the mold core 15 and outside the mold and in the

this laterally adjacent work area 11 is arranged. The element inserting direction 50 is located on the side of the mold core 15 where the core segment 30 with the openings 41 - 44 and receptacles 45 - 48 is arranged,

i.e. in Figures 3 and 4 to the right of the mandrel 15. 30

The element inserter 50 is at least one only schematically indicated magazine 51, in which, one above the other, the individual crampons to be concreted in are stored ready for withdrawal. The magazine 51 be-35

is located above floor level 9, so it is for the operator the Unterfiurmaschine 10 freely accessible, so

that the magazine 51 by the operator between the automatic production process can be refilled with crampons in free time. This refill work is completely independent of the automatic production process. As shown schematically by a base 52 and an axle 53 is indicated, the at least one magazine, viewed within a diametrical plane of the mold core 15, is angularly adjustable for the angle adjustment with different sizes. Also an adjustment for such crampons is possible, which instead of being concreted in the usual way radially to the central axis of the mold core 15, is concreted in parallel should. The removal of crampons stored in the magazine 51 can always take place in the lowest Ma ^ azine area. When they are removed, the crampons located above slide down automatically.

The element insertion device 50 has at least one gripping and Einseczvi rrichtung 60, by means of which a crampon or at the same time several crampons from the magazine 51 removable, on the respective receptacles 45 - 46 in the core segment 30 of the mold core 15, into which they are to be introduced, can be aligned in the correct position and in the associated Recordings 45 - 48 can be used from the outside of the mold core 15. Part of this at least one gripping and insertion device 60 is at least one gripping device 61 which engages in the at least one magazine 51, Take at least one crampon in it, remove it and align it in the respectively assigned receptacle 45 - 48 of the core segment 30 can be used. The gripping device 61 shown can be designed so that they - as is illustrated by the example of Fig. 3 - from the magazine 51 at the same time two crampons 23a and 24a remove and in the manner described above through associated openings 41 and 42 of the core segment 30 in the local recordings 45, 46 can use. It goes without saying that instead of this simultaneous handling in pairs

of crampons, the gripping device 61 is also designed in this way

! It may be that, for example, only one crampon is handled at a time

f> 10 26a (Fig. 4) one holder 62 and 63 and one associated ejection device, for example in the form of a hydraulic working cylinder 64 or 65. The mounts 62, 63 with associated; Working cylinders 64, 65 are

f aligned with each other in space, i.e. in the same way

Stepped shape, as is the case with the openings 41, 42 in the core segment 30 is the case. Both are therefore offset at an angle to one another within the diametrical plane of the mold core 15 and at the same time in the direction of the longitudinal center axis of the

; "Mold core 15. The brackets 62 are oriented in this way,

arranged with their working cylinders 64, 65 on a support part 66, which in turn on a carrier 67 with a

} to the longitudinal center axis of the mold core 15 at least approximately

guided parallel guide 68 and by means of an associated Actuator in the form of a hydraulic, for example

! 2b working cylinder 69 is displaceable. The brackets 62, 63 are angularly adjustable with respect to the carrier 67 within the diametrical plane of the mold core 15 for adaptation to different nominal widths of the concrete parts 12 to be produced is mounted displaceably in a suitable manner, for example by means of two indicated bearing blocks 71, 72 and which is ins-

(special one hydraulic working cylinder in direction

device on the mold core 15 movable into an inserted position which shows Fig. 4, as well as back out of the range of

Molding device can be moved out into the waiting position shown in FIG. 3. The carrier 67 is an integral part of the carriage 70, so that by the movement of the carriage 70 between the insertion position and the waiting position the gripping device 61 in the relevant position is brought. As indicated, the carriage 70 with respect to the mold core 15, within a Seen in the diametrical plane of the mandrel 15, it can be arranged at an angle adjustable on the carrier 6 in order to adapt to it different nominal widths or other desired orientations to enable.

In another exemplary embodiment, not shown if the gripping device has at least one gripper, which clamp a gripped crampon using lockable clamps and after inserting it into the respective assigned receptacle 45-4B of the core segment 30 can be released by opening the clamps. This takes effect Grab each crampon at the end that will later be set in concrete within the concrete of the concrete part 12 is anchored. The gripper is controlled so that its clamps after inserting the at least one crampon will only be geöf.net if this crampon has previously been inserted into the assigned receptacle 45 - 46 held in a slip-proof manner within its receptacle 45-48 by actuation of the associated clamping device 88 is. Compared to the example shown, the working cylinders 64, 65 are omitted here, with the holder 62, 63 is designed as a gripper with gripping jaws. This

Embodiment is suitable with preference for as a stirrup trained climbing elements, which today usually consist of aluminum and are relatively light, so that in the formation of the gripping device in the in Fig. 3 and 4 there would be a risk that the stirrups when retracting such a gripping device on hold within their admission

45-48 slip. The same embodiment is also preferred for the automatic insertion of crampons 23-26, 23a-26a, which are then also clamped to the anchoring ends by means of the gripper will. The elimination of the working cylinders 64, 65 reduces effort and costs. Above all, one is designed in this way Gripping device unchanged on the one hand for the introduction of crampons and, on the other hand, of stirrups equally well suited

The element inserter 50 makes it possible that the individual crampons, e.g. crampons 23a, 24a in the position according to FIG. 3, in the meantime between one ended with removal, preferably ejection, of the finished concrete part 12 from the mold cavity Work cycle and a subsequent new work cycle automatically overlapping the work steps carried out in the meantime Feed core segment 30 and into its receptacles 45-48 can bring in. This can be done while the concrete part 12 in the ejected position shown in Fig. 3 is transported away and on an ejector plate 49 a new lower sleeve 27 is placed for the next following concrete part to be produced. You can use the crampons in the In the meantime, supply the core segment 30 individually one after the other or as several containing groups at the same time and bring 45-4G into its receptacles. It is advantageous if one can already be ejected before the end of one of the finished molded concrete part 12 completed work cycle with a temporal overlap so for the The next concrete part to be produced removes the individual crampons 23a-26a from the magazine 51, with reference to aligns the receptacles 45-48 of the core segment 30 and in this orientation for later feeding and loading ready.

Fig. 3 shows a state during the shaping pro-ZBSSBS, in which the finished molded concrete part 12 with the butt plate 49 and the lower sleeve 27 at the level of the upper edge of the mold core 15, which corresponds to the floor level 9,

B has been ejected upward from the mold cavity. The core segment 30, which moves into the pushed-in release position, as also shown in FIG. 5, during ejection in order to prevent the molded crampons 23 - 26 from getting caught and torn out, must be done immediately after the concrete part 12 has been ejected, it has been moved back into the closed position shown in FIG. 3. the Clamping devices BB - 91 are open, as shown.

Already during the work cycle, in which the according to Fig.3 ejected concrete part 12 has been produced, the element inserting device 50 is based on that shown in FIG. 3 Loading state has been prepared, i.e. the gripping device 61 has been out of the associated at least one magazine 51 new crampons 23a and 24a removed. The gripping and inserting device 60 is located is already in the correct orientation for inserting the crampons 23a, 24a, but in FIG. 3 it is still in the Waiting. As soon as the core segment 30 moves into the closed position shown, the slide together with the carrier 67 and the gripping device 61 horizontally moved forward from the waiting position into the insertion position, to the left in FIG. 3, towards the core segment 30. Then the holder 62 is at the level of the opening 41 with the receptacle 45 there and the holder 63 is at the level of the Opening 42 with a receptacle 46 there. Then the working cylinders 64, 65 are actuated, whereby the crampons 23a or 24a from the respective holder 62 or 63 down through the opening 41 or 42 into the associated receptacle 45 or 46 are pushed. The carriage 70 then moves back into the waiting position according to FIG. Fig. 3 back. The gripping device 61 then removes

the magazine 51 two more crampons 25a, 26a. After that moves the gripping device 61 by actuating the working cylinder 69 in the correspondingly aligned position, so that the holder 62 now rests on the opening 43 with receptacle 47 and the other holder 63 is aligned with the opening 44 and receptacle 4ß. Then will the carriage 70 by its associated drive from the Waiting position in Fig. 4 to the left in that shown there

cylinder 64, 65, the crampons 25a, 26a are ejected and placed in the receptacles 47 and 48, respectively. After that the carriage 70 moves from the insertion position again back in diB in Fig. 3 shown waiting position. The task of the element insertion device 50 is thus first of all Fulfills. During the rest of the operation of the Underfloor machine 10 can now be brought to the loading state again, for example, as can be seen from FIG is.

The described automatic insertion of the individual crampons 23a-26a takes place in an overlapping manner during the time during which the operator of the underfloor machine 10 at the end of the first work cycle nac ^ Concrete part 12 pushed out at the top on the lower sleeve 27 transported away and a new lower sleeve 27 is placed on the ejector plate 4d. The machine using the Insertion of the crampons 23a-26a carried out by the element insertion device 50 is quick, reproducible and safe and relieves the operator of these otherwise very cumbersome and extremely strenuous activities, the were necessary when manually inserting the crampons. So far, this manual introduction has therefore been very disadvantageous affects the cycle time and thus the production speed; because through this manual Activities resulted in very long controllable times for the automatic sequence, with the automatic

As indicated in FIG. 6 only by dashed arrow 182 and as can be seen from FIG. 7, the two assemblies 151a, 151b on the one hand and 151c, 151d on the other hand each for itself within an approximately horizontal plane, predetermined by the carriage 170, along a Arched track kept pivotable. It is both

- 30 -

the first assembly 151a, 151b with its two guide devices 175a, 175b as well as the second assembly 151c, 151d with its guide devices 175c, 175d are aligned along radial lines that are preferably symmetrical to one another, which can only be seen in broken lines in FIG. By pivoting the two assemblies along the arched path as indicated by the arrow, it is possible to precisely set up the core segments for different diameters. The carriage 170 carries an arc segment piece 183a, 183b for each assembly, along which the respective assembly, seated on its carrier 177a or 177b, can be pivoted. Each arcuate segment piece 1B3a, 183b contains, for example, an arcuate elongated hole 184a, 184b, along which a swivel adjustment and, by means of screws, a fixation in the set angular position is possible (FIG. 7).

Each magazine 151a-151d has its own gripping device 161a-161d, which is arranged in the region of the lower end of the magazine 151a-151d. How in particular Fig. 6 shows each gripping device 161a-161d arranged below the respective element guide device 175a-175d in the area of the right-hand end thereof and held on to it.

The gripping device 161a-161d is the same for each individual magazine 151a-151d. It has each magazine 151a 151d a translation drive in the form of a pneumatic one, for example or in particular hydraulic working bit cylinder 164, 164a in the first assembly and 165, 165a in the second assembly, which via its piston rod has a Hooks 185a-185d operated to go back and forth in the horizontal direction. Each hook 185a-185d is located in the area of the lower end of the assigned magazine 151a-151d and engages there through the assigned magazine, for example slot-shaped opening 1BOa, 180b, which in Fig. B for the hooks 185a, 185b of the magazine 151a and 151b can be seen

is. The respective hook 185a-1B5d engages across the Longitudinal axis of the respective magazine 151a-151d in its lower end, the hook 185a-1B5d being the one in the Stack of the respective magazine 151a-151d lowermost element when moving in FIG. 8 to the right below drive and can hook into its interior, behind the transverse part of the element.

So Fig. 8 shows that the hook 185a in the magazine 181a Underside the lowest element 123c and hooked behind the transverse part of this element 123c so that the When moving to the left in FIG. 8, 1B5a hooks this lowermost element 123c out of the magazine 151a can pull and slide into the element guide device 175a, at the same time in the guide device 175a the individual elements stored there are pushed forward by one element length, so that on in Fig. 6-8 left end, which contains the dispensing opening, the element 123a there is discharged from the element guide device 175a and completely ejected, and through the opening 141 of the core segment and into its receptacle.

The same is the case with respect to the rear magazine 151b of the first assembly, in which also the hook 1B5b is the one at the bottom of the magazine stack Element 125d has engaged behind, so that upon displacement of the hook 185b in FIG. 8 to the left by the length of an element 125d this out of the vertical stack is pulled and removed from the magazine 151b and pushed into the element guide device 175b.

For a better overview, further details of this gripping device 161a are shown schematically in FIG. It can be seen that the hook 185a has a stroke which corresponds to at least the length of an element 123f can be pulled out in the direction of arrow 186a and to the left and

is displaceable in the direction of the mold core, which is not visible here, as a result of which the lowermost element 123f is pulled out of the magazine 151a in the direction of arrow 186a and pushed into the guide device. The hook 185a can then be moved back into its starting position in the opposite direction to arrow 186a and in the direction of arrow 186b with an idle stroke. During this idle stroke movement, the hook 185a can move under the element located at the bottom of the magazine 151a, e.g. element 123f, since the hook 185a is pivotably mounted in one direction according to arrow 187 about a horizontal axis 157 on a fork 158 on which the piston rod of the working cylinder 164 engages. By means of a spring, not shown here, the hook 185a can automatically be moved back into the effective position according to FIG. 9 after this tilting movement in the direction of arrow 187 and release. Such tipping hook, which can tilt in a direction according to arrow B ^ 7 free and the opposite direction to the pivoting direction of the arrow 187 are non-tiltable manner, Q ^ are known per se. In the embodiment shown in Fig. 9 this Unkippbarkeit is achieved in that in the fork 158 in distance from the horizontal axis 157, a front stopper 159 is included, where the hook 185a ER in the opposite direction to arrow 187 * ° following restoring movement abuts .

If in the course of the production process by means of the element inserting device 150 through all of them at the same time four openings 141-144 each elements 123a, 125a over the first assembly - and 124a, 126 - over the second assembly - are to be introduced automatically, this is done by switching on the working cylinder the carriage 170 together with the two assemblies resting on it in the horizontal direction towards the core segment

now ready for the next bar.

The length of the individual element guide devices 175a-175d is chosen so that no parts of the element inserter 150, that is, neither the magazines 151a 151d nor the guide devices 175a - ^ SdjDuring of the rest of the manufacturing process in collision with the Machine or parts of it, e.g. the machine's pallet truck. In their retracted position the element guide devices 175a 175d are therefore outside the machine area.

As can be seen, are for the activation of the element insertion device 150 only two additional control functions necessary, namely control of the working cylinder 173 on the one hand and control of the individual working cylinders 164, 164a or 165, 165a of the gripping devices 161a-1B1d on the other hand. This makes control technically no difficulties whatsoever. The element insertion device 150 therefore enables a fully automatic, problem-free Process flow.
