Definitions

  • the invention is preferably used in a precast concrete plant where precast concrete elements are manufactured on a production line – essentially "on an assembly line.”
  • a formwork with a demolding unit is placed on a magnetic or magnetizable formwork base by a formwork robot.
  • Reinforcing elements and, typically, magnetic fixing elements are positioned on the formwork base.
  • These fixing elements must be removed separately from the formwork base after the formwork has been filled with liquid concrete and the finished, hardened concrete element has been removed.
  • Such fixing elements serve, for example, to fix concrete inserts to the formwork base and are distinct from concrete inserts that are embedded in the concrete when the formwork is filled with liquid concrete and are removed from the formwork base after the precast concrete elements have been completed.
  • fixing elements are individually positioned by hand on the formwork base and, after use, individually removed from the formwork base either by hand or with levers. Positioning and removing the fixing elements by hand proves to be time-consuming and uneconomical, as considerable force is required to remove the fixing elements from the formwork base (the holding force to be overcome during removal is typically around 50 to 100 kg).
  • the document discloses a method and a device with which at least the positioning of concrete components is carried out automatically, in particular it discloses a method for positioning fixing elements on a formwork base, comprising the steps: grouping at least two fixing elements into a group of fixing elements in a stacked configuration along a stacking axis and moving the group of fixing elements with a formwork robot parallel to the formwork base into a position above the formwork base, and singulating a fixing element from the group of fixing elements for positioning on the formwork base.
  • EP 1 273 407 A1 discloses a magnet placement robot for spatially positioned placement and/or pickup of magnets - in particular permanent magnets for the arrangement of formwork in the production of precast concrete elements.
  • the present invention is based on the objective of providing a method for positioning fixing elements on a formwork base in order to significantly reduce the workload for a worker when positioning fixing elements on the formwork base, so that cycle times on a production line for the semi-automated production of precast concrete elements in a precast concrete plant can be significantly reduced.
  • the invention provides the method according to claim 1.
  • the fixing elements are moved as a group into the intended position on and/or above the formwork base, separated there, and positioned on the formwork base.
  • moving all fixing elements as a group into the intended assembly position on/above the formwork base eliminates the need for a separate picking step for each individual fixing element.
  • the fixing elements can be separated from the group and positioned on the formwork base independently of one another in different positions.
  • the fixing elements are moved as a group in a housing designed as a magazine above the formwork base and/or individually positioned on the formwork base from the housing designed as a magazine.
  • the movement of the group of fixing elements parallel and perpendicular to the formwork base is carried out by a formwork robot. This further reduces positioning errors when placing the fixing element to be positioned onto the formwork base. Unlike positioning by hand, the fixing element can be positioned on the formwork base with millimeter precision using a robot.
  • This method allows multiple fixing elements to be collected sequentially, particularly automatically, and removed as a group from a formwork base and transported to a delivery station. This eliminates the need to transport individual fixing elements to the delivery station.
  • the fixing elements are collected in a housing designed as a magazine and/or removed as a group from the formwork base in a housing designed as a magazine.
  • step B* at least one remaining fixing element of the group is moved to at least one further position above the formwork base that differs from the aforementioned position, wherein step B and optionally step B* are preferably repeated in each further position, preferably until the last fixing element of the group is positioned on the formwork base, wherein steps A, B and optionally step B* are particularly preferably repeated with at least one further group of fixing elements.
  • the method according to the invention proves to be particularly economical because, in one operation – without a separate start-up of the initial position or refilling station – several fixing elements can be positioned independently of one another on the formwork base.
  • the formwork formed on the base is filled with liquid concrete and the hardened concrete section is removed from the formwork base without the fixing elements.
  • this method no residues remain on the formwork base except for the fixing elements, allowing the formwork base to be used after The removal of the fixing elements allows for the immediate use of another precast concrete element in the production of a new one.
  • steps A and B, and optionally B* can be repeated any number of times after steps C and D have been carried out, using the same fixing elements. Accordingly, the fixing elements previously removed from the formwork base can be repositioned on the formwork base repeatedly.
  • the device 1 serves to position and remove fixing elements 2 on/from a formwork base 3 and comprises a housing/magazine 11 for receiving a group of fixing elements 2 and a support 12, as well as an engagement device 13 for making an engagement with a fixing element 2.
  • the housing 11 is tubular, e.g., made of aluminum/stainless steel (non-magnetic), and comprises two, e.g., plate-shaped extensions 112, which project substantially radially from the hollow cylindrical base part 111 to the central axis M, optionally tapering upwards at their ends, and are connected to the base part 111, e.g., by welding.
  • the interior of the base part 111 preferably tapers conically along the central axis M from top (support 12) to bottom (adjustment device 14) in order to center the fixing elements 2 stored inside with respect to the central axis M and to guide them precisely onto the engagement device 13 described in detail below.
  • Two guide elements/buttons 115 extend parallel to the central axis M on the inner wall of the housing 11 and are spring-loaded in a direction parallel to the central axis M, pre-tensioned into an extended position to rest on the formwork support 3.
  • the guide elements/buttons 115 are designed to engage in the recesses 24 of the fixing elements 2 and, during movement along the central axis M, to guide these elements in a rotationally secure manner within the housing 11, to place them in the correct orientation on the formwork support 3, and to retract them from the formwork support 3 into the housing 11 in the correct orientation.
  • the support 12 is designed as a tube concentric to the base part 111 of the housing 11 and is intended to be held by a worker so that the housing 11 is suspended below the support 12.
  • another adapter such as a hollow square tube with an edge length of 60 mm, can be attached to the wings 122 projecting laterally from the base part 121 of the support 12 via a screw closure 124.
  • This adapter can be used, for example, to be picked up by a formwork robot, similar to a formwork panel.
  • Other adapters or suspensions for the device 1 are also conceivable.
  • Two further wings 125 extending radially to the central axis M, are attached to the underside of the base part 121. These wings are connected by linkage rods 131 to couple the movement of the support 12 relative to the housing 11.
  • the engagement device 13 comprises two slide-shaped engagement sections 134, each of which can be positively engaged with a fixing element 2.
  • the two engagement sections 134 are arranged offset by 180° from the central axis M.
  • the engagement sections 134 are designed to be mirror-symmetrical and simultaneously operable, in order to form-fitting, backlash-free, and fully enclose a fixing element 2 at the neck 22 or between the head 21 and body 23.
  • the number of engagement sections 134 is not necessarily limited to two.
  • each engagement section 134 is coupled to a relative movement between the housing 11 and the support 12 via a joint/toggle lever mechanism formed from the lever rod 131 and lever 132 as well as further deflection rods and joints 133, such that when the overall length of the housing 11 and the support 12 is shortened, each engagement section 134 is spaced away from the central axis M.
  • a joint/toggle lever mechanism formed from the lever rod 131 and lever 132 as well as further deflection rods and joints 133, such that when the overall length of the housing 11 and the support 12 is shortened, each engagement section 134 is spaced away from the central axis M.
  • the distance of the engagement section 134 from the central axis M decreases. This automatically actuates the engagement device 13 when the housing 11 is placed on the formwork base 3, moving it from the closed position to the open position.
  • the engagement device 13 is also automatically actuated, but this time it moves from the open position to the closed position.
  • the inner diameter of a circle formed by the sides of the engagement sections 134 facing the central axis M is smaller than the outer diameter of the head 21 and the body 23 of the fixing element 2, so that the fixing element 2 is positively locked and preferably play-free between the engagement sections 134 in both directions along its axis A.
  • the opening formed between the engagement sections 134 is larger than the outer diameter of the head 21 and the body 23 of the fixing element 2, so that the fixing element 2 can be moved out of the effective range of the engagement device 13 along its axis A, which preferably coincides with the central axis M of the device 1.
  • the strength of the engagement device 13 is dimensioned such that a lifting force directed perpendicular to the contact side of the fixing element 2 can be applied to the fixing element 2 via the engagement sections 134 in order to overcome the magnetic holding force of preferably approximately 87 kg.
  • the central axis M ideally corresponds to the axis A of the engaged fixing element 2 and the stacking axis S, along which the fixing elements 2 can be stacked in the housing 11 with a regular arrangement and orientation (contact side facing down).
  • the adjusting device 14 is, in this case, essentially tubular, e.g., made of aluminum/stainless steel (non-magnetic), and is arranged concentrically along the central axis M outside the base part 111 of the housing 11, allowing it to be adjusted relative to the housing.
  • the adjusting device 14 comprises a hollow cylindrical base part 141 with at least one guide groove for forming a cam guide with a guide pin 114 that projects radially outwards from the base part 111 of the housing 11.
  • the base part 141 includes two further guide grooves for forming a cam guide with a guide pin 114 that projects radially outwards from the base part 111 of the housing 11.
  • the adjusting device 14 is adjustable between a retracted and an extended position by means of a knob 142.
  • the base part 141 of the adjusting device 14 can be fixed in either the retracted or extended position relative to the base part 111 of the housing 11 by means of a knob 142.
  • Four feet 143, which define the base of the device 1 extend from the lower end of the base part 111 of the housing 11, essentially parallel to the central axis M.
  • the device 1 is configurable between a function for positioning fixing elements 2 on a formwork support 3 (extended position of the adjusting device 14) and a function for removing fixing elements 2 from a formwork support 3 (retracted position of the adjusting device 14).
  • the engagement device 13 can be brought into engagement with a fixing element 2 positioned directly on the formwork base 3.
  • the engagement device 13 can be brought into engagement with a fixing element 2 that is placed or stacked on top of the fixing element 2 positioned directly on the formwork base 3.
  • the engagement height of the engagement sections 134 in the retracted position of the adjustment device 14 is dimensioned in relation to the installation surface of the device 1 such that the engagement sections 134 positively, without play, and completely enclose the neck 22 or the constriction formed between the head 21 and body 23 of the fixing element 2 in the closed position.
  • the engagement height of the engagement sections 134 in relation to the installation surface of the device 1 is dimensioned such that the engagement sections 134 enclose the fixing element 2, which is placed on the fixing element 2 positioned directly on the formwork base 3, in a form-fitting, play-free and complete manner in the closed position.
  • the fixing element 2 comprises a mushroom-shaped upper part 2a made of a non-magnetic material, in particular stainless steel or aluminum, and a substantially cylindrical lower part 2b.
  • the upper part 2a of the fixing element 2 forms a head 21 and a neck 22.
  • the lower part 2b forms a body 23.
  • the neck 22 is arranged between the head 21 and the body 23 and forms a taper for a positive-locking connection, e.g., with a concrete insert, as well as for the positive-locking application of a force to lift the fixing element 2 from the formwork base 3.
  • the head 21 and body 23 each comprise a cone 21a, 23a, projecting away from the contact side, to facilitate the engagement of the engagement device 13 or insertion into the housing 11 of the device 1.
  • the head 21, neck 22, and body 23 each comprise a cylindrical surface 21b, 23b, which projects radially away from the axis A of the fixing element 2, perpendicular to the contact side.
  • the change in cross-section between the head 21 and neck 22 forms a radially projecting and circumferential flange 21c, which can be engaged with the engagement device 13 of the device 1.
  • Semi-cylindrical recesses 24 in the outer surface 21b, 23b of the body 23 form an anti-rotation device 24 for the positive locking connection of the fixing element 2, e.g., with a concrete installation element, and for securing it against rotation about an axis perpendicular to the contact side, as well as for rotation-proof guidance on the guide elements/buttons 115 in the housing 11.
  • a cylindrical magnet 2d for fixing the fixing element 2 on the formwork base 3 is located centrally on the contact side of the fixing element 2 in a complementary cavity of the lower part 2b.
  • Another magnet 2c is arranged on the side of the fixing element 2 facing away from the contact side in a complementary cavity of the upper part 2a.
  • This additional magnet 2c is smaller than the magnet 2d for fixing the fixing element 2 on the formwork base 3 and generates a smaller magnetic force.
  • the lower part 2b has a larger diameter than the upper part 2a and forms the contact surface for the fixing element 2 to rest on the formwork base 3.
  • the upper part 2a and the lower part 2b are separate components made of different materials and are connected by a screw that extends through a central bore 2e of the fixing element 2 and into both magnets 2c, 2d.
  • the axes A of the fixing elements 2 are aligned and centered on the central axis M by guiding the cylindrical outer surface 23b of the body 23 on the inner wall of the housing 11 and the recesses 24 on the guide elements/buttons 115 as the movement progresses towards the engagement device 13, and the fixing elements 2 are fed to the engagement device 13 in a positionally accurate manner, so that the engagement sections 134 can penetrate the constriction of the fixing element 2 formed between the head 21 and the body 23 in the closed position.
  • the filling level of housing 11 can be measured from above using a laser or detected in some other way.
  • the neck 22 of the fixing element 2 has a non-rotationally symmetrical, preferably polygonal, outline in cross-section with respect to the axis perpendicular to the mounting surface, by means of which the fixing element can be aligned about this axis.
  • the polygonal outline of the neck 22 is, for example, star-shaped and has four concave recesses on the outside, which taper towards the axis and are arranged symmetrically around the axis at regular angular intervals of 90°.
  • the engagement sections 134 of the device 1 have arrow-shaped tips which have convex outlines complementary to the concave recesses on the neck 22 of the fixing element 2. This allows the fixing element 2 to be aligned around its axis when the two arrow-shaped engagement sections 134 engage in two diametrically opposed recesses.
  • a group is formed from individual fixing elements 2 and arranged regularly in the most compact stack configuration, for example, such that the contact surfaces of the fixing elements 2 each point downwards.
  • the group of fixing elements 2 is fixed in this stack configuration, for example with packing straps. Ideally, this takes place in the factory and outside the formwork system 3 (sub-step A1).
  • the mutual magnetic attraction of the fixing elements 2 supports their stacked arrangement and holds them together in the stack configuration in an arrangement aligned along the stack axis S without any external influence.
  • the fixing elements 2 in this stacked assembly are received from above or below in the housing 11 of the device 1 along a stacking axis S, so that the contact surfaces of the fixing elements 2 face downwards or towards the engagement device 13 (sub-step A2).

  • the engagement sections 134 are moved away from the central axis M by the toggle levers 132 and joints 133, and the engagement device 13 is moved into the open position. This further moves the end of each engagement section 134 pointing towards the central axis M away from the central axis M.
  • the fixing elements 2 fall through the released opening of the housing 11 onto the formwork base 3 and are thereby moved along the stacking axis S (sub-step B2) until the fixing element 2 to be separated rests on the formwork base 3 and is positioned in position P1 (sub-step B3).

Subsequently, the device 1 is lifted from the formwork support 3 by the formwork robot 1 and moved perpendicular to the formwork support 3 in a direction away from it. When the engagement sections 134 move back into the closed position as the housing 11 of the device 1 is lifted from the formwork support 3, the engagement sections 134 engage the second fixing element 2 from below.
