Description

[0001] The invention relates to an alignment device for a laying device for aligning a layer of shaped blocks, which comprises several shaped blocks arranged in rows, and to a laying device.

[0002] DE 10 2004 015 374 A1 discloses a laying device for gripping a layer of shaped blocks. This laying device comprises a frame structure on which a gripping device is provided, which comprises two opposing gripping jaws, wherein the gripping jaws are provided such that they can be moved relative to one another. This gripping device can grip the layer of shaped blocks in the main clamping direction. Furthermore, an alignment device is provided on the frame structure. This alignment device comprises alignment jaws that can be pivoted toward the layer of shaped blocks in a secondary clamping direction. This alignment device comprises a hydraulic cylinder that actuates a pivoting lever device to move the alignment jaw toward the layer of shaped blocks in the secondary clamping direction. This alignment device is actuated with a force and travel speed predetermined by the hydraulic cylinder.This alignment device is designed in such a way that even rows of shaped blocks in the block layer can be aligned offset from one another, which requires a high displacement force, thereby slowing the closing speed of the alignment device. However, such shaped block layers are only installed in a small percentage of cases. Mostly, shaped block layers are installed that require a low displacement force for the offset of the shaped block rows and could be controlled with a higher closing speed. However, due to the high displacement force, this alignment device also requires a considerable amount of time to complete the displacement of the shaped block layer.

[0003] The invention is based on the object of proposing an alignment device for a laying device and a laying device by means of which a simple adaptation to the type of shaped block layers to be laid is possible in order to achieve an optimization, in particular a shortening of the laying time.

[0004] The object underlying the invention is achieved by an alignment device for a laying device, in which a clamping arm is pivotably provided on a base frame for moving or opening and closing, which clamping arm has at least two articulation points for selectively connecting a coupling element from a drive. These at least two articulation points on the clamping arm are arranged at a different distance from the axis of rotation of the clamping arm, about which the clamping arm is pivotally mounted on the base frame. This makes it possible to adjust lever arms of different lengths to generate a pivoting movement on the clamping arm. A larger lever arm on the clamping arm can generate a closing movement of the alignment jaw, which comprises an increased closing force at a reduced closing speed.A smaller lever arm on the clamping arm can generate a closing movement of the alignment jaw, which allows for a reduced closing force at an increased closing speed. This allows for adjustment of the required displacement force for the displacement movement of the respective rows of molded blocks relative to each other, depending on the molded block layers to be handled, in order to achieve optimized installation time, particularly a reduction in installation time. This can also enable increased flexibility for the use of such a laying device.

[0005] It is preferably provided that a first articulation point of the clamping arm is formed at a distance from the axis of rotation on the base frame that is greater than a distance of the at least one further or second articulation point of the clamping arm from the axis of rotation on the base frame. An adjustment of the coupling element for positioning at the first articulation point of the clamping arm is carried out if an increased closing force is required for a sliding movement of the rows of shaped blocks. If the rows of shaped blocks of the shaped block layer to be handled require a lower closing force for the sliding movement, the coupling element is positioned and fixed at the at least one second articulation point of the clamping arm. This adjustment enables time-optimized laying of the respective shaped block layers.

[0006] Advantageously, the articulation points are each designed as separately aligned openings, open-edged recesses, or perforations on or in the clamping arm. This allows for easy manufacture of the articulation points on or in the clamping arm. Preferably, the coupling element of the drive can be relocated between the at least two mutually different articulation points or mounted thereon.

[0007] Alternatively, it can be provided that the at least two articulation points are arranged or integrated in a guide. This can be an open or, preferably, a closed guide, within which the coupling element of the drive is displaceably guided between the at least two mutually differing articulation points and can be fixed therein.

[0008] The coupling element can be designed as an end piece with a through-hole or as a U-shaped or fork-shaped end piece with through-holes located in one axis.

[0009] Preferably, the coupling element of the drive is detachably connected to the respective pivot point of the tensioning arm by a lock. This allows for quick and easy installation of the coupling element from one pivot point to at least one other pivot point. This lock is preferably also suitable for construction sites.

[0010] A positive and / or non-positive connection is preferably formed between the clamping arm and the coupling element by the closure.

[0011] This allows both high closing forces and closing speeds to be transferred to the alignment jaw of the alignment device.

[0012] Furthermore, it is preferably provided that the closure has at least one securing element by which the closure is secured on the clamping arm in an engaging position on the clamping arm and the coupling element.

[0013] For example, the securing element can be designed as a tab with a bore that can be connected to the clamping arm via a detachable connection, in particular a screw connection. The securing element can also be designed as a plug-in spring clip or as a locking pin that can be attached to the clamping arm.

[0014] The closure may, for example, comprise a plug-in pin, a clamping element or a plug-in element which can be positioned in an opening in the coupling element and at the same time can be connected to the respective articulation point.

[0015] According to a further preferred embodiment of the alignment device, the clamping arm is designed as a single lever arm. The at least two pivot points are provided on this lever arm. Alternatively, the clamping arm can also be designed as a multi-part lever arm mechanism. This allows, for example, larger gripping widths to be achieved.

[0016] The drive of the attachment device can, for example, be designed as a lifting cylinder with a lifting cylinder rod as the actuating element. This lifting cylinder can be driven electrically, hydraulically, or pneumatically.

[0017] The object underlying the invention is further achieved by a laying device for gripping a layer of shaped blocks, in which at least one alignment device according to one of the embodiments described above is provided.

[0018] This alignment device is preferably detachably mounted on a support frame of the laying device. This also allows for different alignment devices to be provided on the support frame of the laying device, for example, to easily convert the support frame to different sizes or formats of the shaped blocks and / or shaped block layers.

[0019] Furthermore, it can be provided that two alignment devices are provided on the holding frame of the laying device, spaced apart from one another and aligned in opposite directions, and whose spacing can be adjusted. This, in turn, increases the flexibility in handling the laying device for different formats of the shaped block layers.

[0020] The invention, as well as further advantageous embodiments and developments thereof, are described and explained in more detail below with reference to the examples shown in the drawings. The features shown in the description and the drawings can be used individually or in any combination according to the invention. They show: Fig. 1 a perspective view of a laying device, Fig. 2 a further perspective view of the laying device according to Fig. 1, Fig. 3 a perspective view of an alignment device of the laying device according to Fig. 1, Fig. 4 a schematic side view of the alignment device according to Fig. 3 in an arrangement for a high alignment force, Fig. 5 a schematic side view of the alignment device according to Fig. 4 in an open position, Fig. 6 a schematic side view of the alignment device according to Fig. 3 in an arrangement for a rapid closing movement of the alignment jaw, Fig. 7 a schematic side view of the alignment device according to Fig. 6 in an open position, Fig. 8 a perspective view of a closure, Fig. 9 a perspective view of a layer of shaped bricks, Fig. 10 is a schematic side view of an alternative embodiment to Fig. 5 in an arrangement for a high alignment force, and Fig. 11 a schematic side view of the alternative embodiment according to Fig. 10 in an arrangement for a rapid closing movement of the alignment jaw.

[0021] In Fig. 1 is a schematic view of a laying device 11 for gripping a layer of shaped blocks 63 ( Fig. 9). This laying device 11 comprises at least one holding frame 12, on which a gripping device 13 with two opposing gripping jaws 14, 15 is provided in a first direction. These gripping jaws 14, 15 are aligned in a main clamping direction. For example, it can be provided that one gripping jaw 14 is designed as a fixed gripping jaw and the second gripping jaw 15 as an openable or pivotable gripping jaw, or vice versa. Both gripping jaws 14, 15 can also be pivotable.

[0022] In another direction, in a secondary clamping direction, two alignment devices 16, 17 are provided on the holding frame 12, in particular detachably attached thereto. Each alignment device 16, 17 comprises an alignment jaw 18, 19, which is pivotally mounted relative to a base frame 21 of the alignment device 16, 17. Fig. 1, the alignment jaws 18, 19 of the alignment device in 16, 17 are shown in a closed position and in a gripping position, respectively.

[0023] In Fig. 2, the laying device 11 is shown in Fig. 1, wherein one alignment jaw 18 of the alignment device 16 is shown in an open position and the other alignment jaw 19 of the alignment device 17 is shown in a closed position. The alignment jaws 18, 19 are preferably controlled synchronously, so that both are simultaneously moved from an open position to a closed or alignment position and engage the molded block rows 65 of the molded block layer 63.

[0024] The at least one gripping jaw 14, 15 and the alignment jaws 18, 19 are preferably controlled by a hydraulic circuit. For example, a hydraulic cylinder for opening and closing the at least one gripping jaw 14, 15 and preferably a hydraulic cylinder for opening and closing the alignment jaws 18, 19 are controlled by a control system (not shown in detail). A connection interface 20 is provided on the holding frame 12 so that the laying device 11 is accommodated by a carrier device (not shown in detail), such as an excavator, a wheel loader, or a laying machine, in order to grip the shaped block layer 63 and transfer it to a laying location.

[0025] The alignment jaw 18, 19 is preferably designed as a C-shaped profile. An attachment device 22 can be attached to this alignment jaw 18, 19. This attachment device 22 can comprise several displacement elements 23 in order to engage the shaped block rows 65 and to displace them relative to one another. The example shown in Fig. The sliding element 23 shown in Figure 1 is designed as a pin.

[0026] In Fig. 3 shows a perspective view of the alignment device 16. The alignment device 17 is preferably constructed identically, so that only the alignment device 16 is described below. Fig. 4, the alignment device 16 is shown in a side view. The alignment device 16 according to the Fig. 3 and Fig. 4 is arranged in a closed position or a gripping position for a sliding movement of the shaped block rows 65 of the shaped block layer 63. A mounting plate 24 or a connection point is provided on the base frame 21, by means of which the alignment device 16 is detachably fastened to the holding frame 12. At the same time, a distance between the opposing alignment devices 16, 17 on the holding frame 12 can be adjusted via this mounting plate 24 or a connection point. The base frame 21 preferably has a U-shaped cross-section, with the mounting plate 24 merging into the laterally upwardly projecting legs 25. At an upper end of the legs 25, a support element 27 is provided, which accommodates a left and right lever mechanism 28, by means of which the alignment jaw 18 is pivotably mounted about a rotation axis 31.

[0027] A drive 32 is provided in the base frame 21. This drive 32 is designed as a lifting cylinder. At one end, the lifting cylinder is fixed, for example, between the legs 25 of the base frame 21. Opposite, an extendable actuating element 34 is provided, which has a coupling element 36 at its free end. The coupling element 36 can be designed as a bearing with an opening. The drive 32 is connected to the coupling element 36 on a clamping arm 37. The clamping arm 37 is pivotally mounted on the base frame 21 about a rotation axis 38. Advantageously, the rotation axis 38 of the clamping arm 37 can deviate from the rotation axis 31 of the lever arm mechanism 28 with respect to the base frame 21, in particular with respect to the mounting plate 24. For example, a further lever arm 39 is provided on the clamping arm 37, which is coupled to the alignment jaw 18.

[0028] The clamping arm 37 has at least two pivot points 41, 42. These two pivot points 41, 42 are provided at a different distance from the rotational axis 38 of the clamping arm 37. A releasable closure 44 is provided to fix the coupling element 36 to the respective pivot point 41, 42. This closure 44 forms a positive and / or non-positive connection between the respective pivot point 41, 42 and the coupling element 36. This closure 44 can be easily released, so that the coupling element 36 can be quickly transferred from one pivot point 41 to the at least one further pivot point 42 and connected thereto. In this embodiment, the pivot points 41, 42 are designed as a bore or opening in the clamping arm 37 according to the alignment device 16. Alternatively, it can also be provided that the articulation point 41, 42 is formed by a recess with an open edge.In this case, the pivot point 41, 42 can preferably be formed by an L-shaped recess. The pivot points 41, 42 provided on the clamping arm 37 can be of the same design.

[0029] The clamping arm 37 can be formed, for example, by a single plate or a single lever. Alternatively, the clamping arm 37 can be formed as shown in Fig. 3 may be formed by two plates aligned parallel to one another, with the coupling element 36 positioned between these two plates and fixed to the clamping arm 37 by the closure 44. The clamping arm 37 is formed in one piece with respect to the rotation axis 38 and the at least two articulation points 41, 42.

[0030] It can also be provided that the clamping arm 37 is constructed in several parts, i.e., that the plate or lever is formed from at least two components that can pivot relative to one another. These components can also be arranged at a distance from one another, in order to accommodate the coupling element 36 between them.

[0031] The drive 32 is connected to the clamping arm 37 at the pivot point 41 ( Fig. 4). This pivot point 41 is at a greater distance from the rotation axis 38 than the at least one further pivot point 42. This arrangement enables a pivoting movement of the alignment jaw 18 onto the molded block layer 63 with an increased gripping force or displacement force at a reduced closing speed.

[0032] In Fig. 5 is a schematic side view of the attachment device 21 according to the Fig. 3 and Fig. 4 in an open position of the alignment jaw 18. After aligning the shaped block rows 65 of the shaped block layer 63 with each other, the alignment jaw 18 is opened again. Subsequently, the mutually displaced shaped block rows 65 are gripped by the gripping jaws 14, 15 in order to transfer them to the installation location. The control of the opening position of the alignment jaw 18, 19 according to Fig. 5 is necessary so that the shaped block layer 63 can also be laid directly adjacent to a wall. The alignment jaws 18, 19 of the alignment device 16, 17 therefore do not hinder such installation.

[0033] In Fig. 6 shows a schematic side view of the alignment device 16. The coupling element 36 of the drive 32 is positioned in the second articulation point 42 of the clamping arm 37. In this embodiment, it is provided that due to the shorter lever arm between the rotation axis 38 and the articulation point 42 in comparison to the lever arm according to Fig. 4 between the rotation axis 38 and the first pivot point 41, a faster closing movement of the alignment jaw 18 is possible. However, due to the reduced lever arm, the application of a reduced gripping force or displacement force to the molded block layer 63 is possible.

[0034] In Fig. Figure 7 shows a schematic side view of the alignment device 16 of the alignment jaw 18 in an open position. Even when the coupling element 36 of the drive 32 is connected to the pivot point 42 of the clamping arm 37, the gripping jaw 18 can be fully opened, allowing unhindered installation of the shaped block layer, for example, directly adjacent to a wall or the like.

[0035] The releasable closure 44 is, according to a possible embodiment, in Fig. 8. The releasable closure 44 comprises a plug pin 46, which is provided on a securing element 47. The securing element 47 is designed, for example, as a tab with a bore 48, which is firmly connected to the plug pin 46. This securing element 47 can be secured to the clamping arm 37, for example, via a releasable connection, in particular a screw connection. This enables quick and easy assembly and disassembly. Other alternative embodiments, which enable easy assembly and disassembly of the coupling element 36 to the clamping arm 37, can also be used.

[0036] The detachable closure 44 allows the alignment device 16 to be easily converted to the respective requirements or the force to be applied for the respective molded block layer 63. The securing element 47 is released from the clamping arm 37, so that the closure 44 can then be removed. The coupling element 36 is moved from the one pivot point 41 to at least one other pivot point 42, or vice versa. The closure 44 is then reassembled and secured.

[0037] This arrangement thus has the advantage that, with the same drive 32, different closing forces or different closing speeds can be applied to the alignment jaw 18 depending on the positioning of the coupling element 36 to the clamping arm 37.

[0038] The articulation points 41, 42 on the clamping arm 37 can, for example, be spaced apart from one another relative to the rotational axis 38 such that, when the drive 32 engages at the articulation point 41, a closing force up to 50 or 60 percent higher than at the articulation point 42 can be achieved. When the coupling element 36 of the drive 32 is positioned at the articulation point 42, a speed up to 50 or 60 percent higher in the opening and closing movement of the alignment jaw 18 can be achieved. The respective increase in force or speed depends on the length of the clamping arm 37 or the distance from the articulation points 41, 42 to the rotational axis 38 on the base frame 21.

[0039] In Fig. 9 shows a perspective view of a layer of shaped blocks 63. This layer of shaped blocks 63 comprises several rows of shaped blocks 65, which are formed from several consecutive shaped blocks 64. Two adjacent rows of shaped blocks 65 are displaced relative to each other by the laying device 11, so that they are Fig. 9, for example, can be converted into a runner assembly. When the alignment jaws 18, 19 are closed, the offset of the shaped block rows 65 relative to one another is enabled by the displacement elements 23 of the attachment device 13. During the displacement movement, the gripping jaws 14, 15 are open in the main clamping direction. After the shaped block rows 65 have been offset relative to one another by the alignment devices 16, 17, the alignment devices 16, 17 are opened and the gripping jaws 14, 15 are closed, so that the shaped block layer 63, which is provided, for example, on a pallet, can be transferred to the installation site.

[0040] In the Fig. 10 and Fig. 11 is an alternative embodiment of the alignment device 16 to the Fig. 3 to 7. This alignment device 16 differs in the design of the clamping arm 37 from the embodiment according to the Fig. 3 to 7. In this embodiment, it is provided that the at least two articulation points 41, 42 are provided or integrated in a guide rail 51. The articulation point 41 and the articulation point 42 can be located in the respective end region of the guide rail 51. Additional articulation points can be provided in between. The guide rail 51 enables continuous adjustment of the coupling element 36 between the end regions of the guide rail 51. This guide rail 51 can be straight, curved, or arched. As a result, various force and / or speed profiles for controlling the alignment jaw 18 can be achieved.

[0041] The gate 51 has the advantage that, for example, the fixed position of the coupling element 36 within the gate 51 is released, subsequently enabling a guided sliding movement of the coupling element 36 with the closure 44 along the gate 51. The closure 44 can be adapted or modified accordingly, for example, by clamping to fix any desired position of the coupling element 36 relative to the gate 51. QUOTES CONTAINED IN THE DESCRIPTION
