Description

[0001] The invention relates to a method for operating a laying device for handling a layer of shaped bricks, which comprises several shaped bricks arranged in rows, and to a laying device.

[0002] From DE 10 2006 042 564 A1, a laying device for handling a layer of shaped bricks is known. This laying device comprises a holding frame with a gripping device arranged thereon, which includes gripping jaws designed to generate a primary clamping force on the layer of shaped bricks and actuated by at least one gripping cylinder. At least one alignment device with alignment jaws is provided on the holding frame, which is designed to generate a secondary clamping force on the rows of shaped bricks and can be actuated by at least one alignment cylinder. Furthermore, a pressing device is provided, which includes at least one pressing jaw that acts on the layer of shaped bricks and can be actuated by at least one pressing cylinder. The laying device includes a control arrangement by which the gripping jaws, the alignment jaws, and the pressing jaws can be controlled.A cam control device, driven by a motor, is used for this purpose. The cam control device has several cams, each of which actuates a control valve to control the opening and closing movements of the gripping cylinder, the alignment cylinder, and the ejector cylinder. This cam control device enables precise control. A defined sequence of individual process steps is provided for with this cam control device. Conversion or adaptation to a different sequence of process steps is time-consuming.

[0003] From DE 20 2007 014 578 U1 a laying device is known in which a hydraulic motor is provided for its power supply, which simultaneously with the pressure build-up in the hydraulic line drives an electric generator which generates electrical energy at an output line to supply an electrical control device.

[0004] The invention is based on the objective of proposing a method for operating a laying device for handling a layer of shaped bricks, a laying device and a control device for the laying device, which can be easily adapted to different processes and / or requirements for handling layers of shaped bricks.

[0005] This problem is solved by a method for operating a laying device for handling a layer of shaped bricks with a laying device, in which a laying device with a holding frame is provided, on which a gripping device with gripping jaws is arranged, which are designed to generate a main tension on the rows of shaped bricks and can be actuated by at least one gripping cylinder in a control circuit of a hydraulic circuit, on which an alignment device with alignment jaws is arranged, which are designed to generate a secondary tension on the rows of shaped bricks and can be actuated by at least one alignment cylinder in a further control circuit of the hydraulic circuit, on which a pressing device with at least one pressing jaw is arranged, which is designed to press the rows of shaped bricks and can be actuated by at least one pressing cylinder in a further control circuit of the hydraulic circuit.and in which an opening and closing movement of the gripping jaws and / or the alignment jaws and / or the ejector jaw is controlled by a control device, wherein the control device comprises a digital data processing device which is connected via at least one electrical interface to at least one electrical control valve in which at least one control circuit is stored and in the digital data processing device of the control device at least one program for handling the molded stone layer is stored and the program for handling the molded stone layers is selected for handling,which controls the laying device for handling the layer of shaped bricks. One or more programs can be stored in the data processing unit. The programs can differ from each other in the successive process steps, or be arranged in any order, and / or omit or add individual process steps for controlling the gripping device, the alignment device, and / or the pressing device, and can be individually adapted to the layer of shaped bricks to be laid. This allows for flexible use of the laying device, in particular the same laying device, for different layers of shaped bricks, as well as reduced handling time. Furthermore, a conversion of the existing cam control is no longer necessary. Only the selection of the appropriate program is required.

[0006] According to a preferred embodiment of the method, after selecting the appropriate program in the data processing unit, the laying device is aligned with the layer of shaped blocks for handling, and subsequently, the selected program for handling the layer of shaped blocks is started by a start signal or a control signal. This can be done, for example, by an operating lever or hand control of the carrier device, by a remote control, or by activating an app on a mobile communication device.

[0007] Furthermore, it is preferably provided that in a first phase of the program, a gripping program is initiated and its process steps are executed. In a simple embodiment of the gripping program, the laying device for handling the layer of shaped bricks is closed and the layer of shaped bricks is gripped. In a second phase of the program, a placement program can be initiated and its process steps executed. In a simple embodiment of the placement program, the laying device is opened and the layer of shaped bricks is placed.

[0008] Preferably, a program for handling the layer of shaped blocks includes at least one gripping program. This gripping program comprises at least the following process steps, which are preferably executed sequentially: closing the gripping device, opening the gripping device, closing the alignment device, closing the gripping device, and opening the alignment device. These sequential process steps allow the layer of shaped blocks to be aligned in both the main and secondary tensioning directions, so that the shaped blocks are positioned close together and then gripped for transfer to the laying location by the laying device.

[0009] Preferably, a program for handling the layer of shaped bricks includes at least one placement program. This placement program preferably comprises at least the following process steps, which can preferably be controlled sequentially: opening the gripping device, moving the pressing device downwards. This allows for the simple placement of the layer of shaped bricks at the laying location, with the pressing device designed to transfer the row of shaped bricks adjacent to the already laid row completely onto the subgrade and position them directly adjacent to the already laid layer of shaped bricks.

[0010] Preferably, fixed, sequential process steps are selected and stored for the first and second phases in the respective program for handling the layer of shaped bricks. This allows different programs to be saved for different arrangements. By selecting the appropriate program, the operation of the laying device can be individually adapted to different layer configurations with regard to the size of the shaped bricks, the positioning of the rows of shaped bricks relative to each other, and the like.

[0011] Advantageously, the end of each program phase can be indicated to the operator by a visual, audible, and / or haptic signal. This allows the operator to be informed about the current status of the program's progress. In particular, after the first phase has ended, the operator can be notified that the layer of shaped blocks has been gripped correctly by the laying device and can then be transferred to the installation location.

[0012] Furthermore, it is preferably provided that at least one end position of the opening and / or closing movement of the gripping jaws, the alignment jaws, and / or the upper and / or lower stroke end position of the ejector jaw is monitored, time-controlled and / or with at least one pressure sensor and / or a sensor element, particularly for position detection, and that a control signal is transmitted from the detected end position to the data processing device. After the adjustable time period has elapsed and / or the end position has been detected, a further process step can be initiated and / or a signal can be output to the user. This enables monitoring of the individual process steps within the various phases of the program.

[0013] According to a further preferred embodiment of the method, a test program is stored in the data processing unit. This test program can be executed after connecting the laying device to a carrier vehicle, excavator, or the like, or at the beginning of each workday or laying operation, in order to check the functionality of the laying device.The test program may, for example, comprise one or more process steps, in particular the following process steps listed and sequentially: closing the gripping jaws, fully opening the gripping jaws, preferably closing and reopening the gripping jaws again, closing the alignment jaws, opening the alignment jaws, preferably closing and reopening the alignment jaws again, lowering the ejector jaw, raising the ejector jaw, preferably lowering and raising the ejector jaw again.

[0014] Advantageously, a reset function can be implemented to reset the last executed program step and then re-execute it. This reset function offers the advantage that a program step can be restarted if it was not executed correctly. This reset function can also be activated during or after any program step of the selected program. Furthermore, this reset function allows the process step to be reset and not executed if a danger is imminent.

[0015] According to a further preferred embodiment of the method, a calibration program is stored in the data processing unit. This calibration program comprises the following successive process steps: closing the gripping device and detecting the pressure of the gripping cylinder in the closed position using the pressure sensor; comparing the detected pressure in the closed position of the gripping cylinder with the stored pressure for the gripping position; and adjusting the detected pressure to the stored pressure for the gripping cylinder. Analogous procedures can be provided for the alignment device and / or the ejection device.The calibration program for the alignment device can include the following sequential process steps: closing the alignment device and measuring the pressure applied to the alignment cylinder in the closed position using the pressure sensor; comparing the measured pressure in the closed position of the alignment cylinder with the stored pressure for the alignment position; and adjusting the measured pressure to the stored pressure for the alignment cylinder. The calibration program for the bead breaker can include the following sequential process steps: closing the bead breaker and measuring the pressure applied to the bead breaker cylinder in the bead breaker position using the pressure sensor; comparing the measured pressure in the bead breaker cylinder's bead breaker position with the stored pressure for the bead breaker position; and adjusting the measured pressure to the stored pressure for the bead breaker cylinder.This allows for adjustment to the current pressure in the hydraulic circuit of the carrier device to which the laying device is connected.

[0016] The object underlying the invention is further solved by a laying device for handling a layer of shaped bricks, which has a control unit for controlling an opening and closing movement of the gripping jaws, the alignment jaws and / or the pressure jaw, wherein the control unit comprises a digital data processing unit which can be connected via at least one electrical interface to at least one electrical control valve in the at least one control circuit and in which at least one program for handling the layer of shaped bricks can be stored. This enables a simple and quick conversion of the laying device to the layer of shaped bricks currently being laid. It is only necessary to call up the appropriate program from the data processing unit to handle the newly laid layer of shaped bricks.

[0017] Preferably, the control device for controlling a hydraulic circuit of the laying device comprises a control circuit for the opening and closing movement of the gripping jaws, the alignment jaws, and / or the ejector jaw, each with an electrically controlled control valve. Preferably, an electrical control valve is provided for each of the at least one gripping cylinder, the at least one alignment cylinder, and the at least one ejector cylinder. This allows for individual control.

[0018] Furthermore, the data processing unit can be provided with an interface for at least one pressure sensor and / or at least one sensor element for detecting at least one position and / or one end position of the gripping jaws, the alignment jaws, and / or the ejector jaw. This allows the detected positions and / or end positions to be transmitted as control signals to the data processing unit and evaluated by the pressure sensor and / or the sensor element. Preferably, at least one pressure sensor is provided in each control circuit.

[0019] Furthermore, the data processing device may include at least one interface for reading and / or reading data and / or programs. This allows for the easy installation of updates and new programs. Additionally, the data processing device can be easily accessed to record the activities performed or error messages in a log.

[0020] Furthermore, it may be preferable to provide an additional interface on the data processing unit for transmitting a control signal from a handheld controller of a carrier device. This allows the operator to communicate directly with the data processing unit on the laying device from the carrier device in order to select the appropriate program for handling the layer of shaped bricks.

[0021] The data processing device preferably comprises a display and preferably a keyboard, via which a stored program in the data processing device can be selected. Alternatively or additionally, it may be provided that a stored program in the data processing device can be selected via a remote control. Furthermore, it may be provided that a stored program in the data processing device can be accessed via an app on a mobile communication device. Additionally, it may be provided that a stored program in the data processing device can be selected by hand control on the carrier device, in particular a joystick.

[0022] A battery is preferably provided to supply power to the control unit. In particular, this is designed as a replaceable battery. Advantageously, the at least one replaceable battery includes battery management. Additionally, a further battery management system can be provided in the control unit. This allows energy consumption during operation with the carrier device and the laying device to be reduced to a minimum. In particular, a supply voltage from the replaceable battery is only required when outputting the necessary control signals and / or when acquiring signals from the at least one control valve and / or the at least one pressure sensor or the like.

[0023] The object underlying the invention is further solved by a control device for operating a laying device for handling a layer of shaped bricks, which comprises a digital data processing device in which at least one program for handling the layer of shaped bricks is stored and can be called up to control the laying device. This control device can be designed as a single unit, in particular also as a retrofit kit, so that the laying device can be easily equipped or existing laying devices can be retrofitted. This can increase the flexibility in the use of the laying device.

[0024] Preferably, the control device includes at least one electronic interface for controlling electric control valves in a hydraulic circuit. This enables quick retrofitting to existing laying devices. The control device can then be attached, for example, to a mounting frame of the laying device. This also allows a desired program to be called up directly on the data processing device at the laying device.

[0025] 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 that can be derived from the description and the drawings can be applied individually or in any combination according to the invention. The drawings show: Figure 1 is a perspective view of a laying device, Figure 2 is another perspective view of the laying device according to Figure 1 Figure 3 is a schematic side view of a pressing device of the laying device, Figure 4 is a perspective view of a data processing device with an accumulator of the laying device according to Figure 1 Figure 5 shows a schematic view of a control device with a hydraulic circuit of the laying device according to Figure 1 Figure 6 is a schematic view of process steps of a laying program, Figure 7 is a schematic view of process steps of a test program, Figure 8 is a schematic view of process steps of a calibration program, Figure 9 is a top view of a layer of shaped stone to be laid, and Figure 10 is a top view of a layer of shaped stone to be laid in a semi-bonded pattern.

[0026] In Figure 1schematically, a laying device 11 for gripping a layer of shaped stone 63 ( Figure 9 ) shown. 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, one gripping jaw 14 can be designed as a fixed gripping jaw and the second gripping jaw 15 as an opening or pivoting gripping jaw, or vice versa. Both gripping jaws 14, 15 can also be pivotable. The at least one gripping jaw is actuated for opening and closing by at least one gripping cylinder 20.

[0027] In another direction, in a secondary clamping direction, two alignment devices 16, 17 are provided on the retaining frame 12, in particular detachably attached to it. Each alignment device 16, 17 comprises an alignment jaw 18, 19, which is pivotably mounted to a base frame 21 of the alignment device 16, 17. Figure 1 The alignment jaws 18, 19 of the alignment device are shown in 16, 17 in a closing position and in a gripping position, respectively.

[0028] In Figure 2 The laying device 11 is in accordance with Figure 1The figure shows one alignment jaw 18 of the alignment device 16 in an open position and the other alignment jaw 19 of the alignment device 17 in a closed position. The alignment jaws 18, 19 are actuated, preferably synchronously, by at least one alignment cylinder 21, so that both are simultaneously moved from an open position to a closed position or alignment position and engage the form block rows 65 of the form block layer 63.

[0029] The alignment jaw 18, 19 is preferably designed as a C-shaped profile. An attachment device 22 can be fastened to this alignment jaw 18, 19. This attachment device 22 can comprise several sliding elements 23 to engage the rows of shaped blocks 65 and move them relative to one another. The example shown in Figure 1 The depicted sliding element 23 is designed as a pin.

[0030] The laying device 11 further comprises a pressing device 22. This is shown by way of example in a side view in Figure 3 This ejection device 22 is preferably fixed to the holding frame 12. The ejection device 22 comprises at least one pressure jaw 23. This pressure jaw 23 advantageously extends adjacent to one of the gripping jaws 14, 15. The pressure jaw 23 can, for example, be designed as a tube or a C-profile.

[0031] The pressure jaw 23 is actuated so that it can move up and down relative to the holding frame 12. It is preferable that the pressure jaw 23 is held in an upper position against a spring force by a release cylinder 26. As soon as the release cylinder 26 is deactivated, the release jaw 23 is moved downwards, thereby pressing the formwork block 63 downwards onto the laying location. Alternatively, the function described above can be reversed. This allows the formwork block 63 to be pressed downwards after it has been positioned at the laying location and the gripping device 13 has been opened.

[0032] According to the, the mounting frame 12 is Figures 1 and 2A connection interface 20 is provided so that the laying device 11 is picked up by means of a carrier device not shown in detail, such as an excavator, a wheel loader or a laying machine, in order to grip the layer of shaped stone 63 and transfer it to a laying location.

[0033] Furthermore, at least one interface 43, 44 for a hydraulic circuit 42 is provided at the connection interface 20. This allows the laying device 11 to be controlled by a hydraulic pressure supplied by the carrier device for controlling the gripping device 13, the alignment device 16, 17 and / or the pressure-cutting device 22.

[0034] In Figure 4A control device 31 is shown schematically. This control device 31 is provided in a housing 32. This housing 32 can be detachably attached to the mounting frame 12 of the laying device 11. The control device 31 comprises a data processing unit 33, which is positioned inside the housing 32. This data processing unit 33 can be operated via a display 34 or an adjacent keypad 35. Instead of or in addition to the display 34, a remote control or a mobile communication device can also be provided to control the data processing unit 33.

[0035] A battery 36 is provided to supply power to the control unit 31, in particular the data processing unit 33. This battery 36 is replaceably attached to an interface 37 in the housing 32. This interface 37 is accessible via a preferably closable housing opening 40. Advantageously, the control unit 31 is provided with at least two batteries 36. One of the two batteries 36 is intended for operation, and the other battery 36 can be recharged during this time in a charging station (not shown in detail).

[0036] Furthermore, one of several interfaces 38 of the data processing device 33 is shown as an example. This interface 38 can, for example, be in the form of a plug for a connector. In addition, further interfaces 39 can be provided, which are designed for wireless data transmission.

[0037] The housing 32 is preferably designed as a closed housing. This is both sufficiently rigid and therefore suitable for construction sites, as well as weather-resistant.

[0038] In Figure 5 Figure 3 shows a schematic view of the control device 31. The data processing device 33 is connected to the switching and / or control components of the hydraulic circuit 42 via at least one electrical interface 44 and to the hydraulic components of the hydraulic circuit 42 via at least one hydraulic interface 43.

[0039] The at least one gripping jaw 14, 15, the alignment jaws 18, 19 and / or the pressure jaw 23 are preferably controlled by means of the hydraulic circuit 42. For example, the hydraulic gripping cylinder 20 is provided for opening and closing the at least one gripping jaw 14, 15 and preferably a hydraulic alignment cylinder 21 each for opening and closing the alignment jaws 18, 19 and in particular a pressure cylinder 26 for lowering and raising the pressure jaw 23.

[0040] The hydraulic interface 43 comprises two main connections through which hydraulic fluid is supplied to and discharged from the carrier device via a hydraulic motor (not shown). Control valves 71, 72, and 73 are provided for controlling at least one gripping cylinder 20, one alignment cylinder 21, and one ejector cylinder 26, respectively. Each of these valves can be individually controlled by the data processing unit 33 via control lines 83, 84, and 85. Control valves 71, 72, and 73 each control a control circuit 75, 76, and 77 for the opening and closing movement of the at least one gripping cylinder 20, the at least one alignment cylinder 21, and the ejector cylinder 26, respectively. A pressure sensor 79 can be provided within each control circuit 75, 76, and 77 for monitoring the control circuit. This pressure sensor 79 is preferably connected to the data processing unit 33.Furthermore, it can be provided that at least one gripping cylinder 20, at least one alignment cylinder 21, and at least one ejector cylinder 26 are each assigned at least one sensor element 81 in order to detect at least one end position of the respective cylinders 20, 21, and 26. The at least one end position can be an extended or retracted position, or a closed or open position, and / or a partially open and / or partially closed position of the gripping device 13, the alignment devices 16 and 17, and / or the ejector device 22.

[0041] The data processing unit 33 can store one or more programs 46, or may already contain them. Application-specific configurations of individual programs 46 can also be stored in the data processing unit 33. Each of these programs 46 can be adapted to a specific handling process to enable fast, safe, and / or controlled handling of the formwork block 63.

[0042] For example, a key switch can be provided to start the data processing unit 33. This switch serves to open the housing 32 and insert the accumulator 36, and / or to move the data processing unit 33 into a start position. The required program 46 can then be accessed via the display 34 and / or the keypad 35. After operation of the laying device 11, this key switch can be pulled. It can be provided that this disconnects the data processing unit 33 from the power supply.

[0043] The respective program 46 can be accessed, started, and terminated via the display 34, which can also be a touch display, and / or via the keyboard 35 adjacent to the display 34. The display 34 shows the status of the data processing unit 33 or the respective program 46.

[0044] The respective program 46 can be composed of several successive process steps 49, 50, etc. Each process step 49, 50, etc. is assigned to a defined operation for controlling the laying device 11. These process steps 49, 50, etc. can be stored in different sequences. Individual process steps can also be omitted or skipped.

[0045] Program 46 can, for example, consist of or be composed of a gripping program 47 and / or a placement program 48. Various process steps can be assigned to each of the gripping program 47 and the placement program 48, resulting in a manifold number of programs 46. The gripping program 47 includes at least the operation of the placement device 11 gripping the layer of shaped bricks 63 to be laid. Following this, the placement device 11 can be moved to the placement location. Subsequently, the placement program 48 can be activated, which includes at least the operation of placing the layer of shaped bricks 63 at the placement location.

[0046] For example, the following process steps can be assigned to gripping program 47. Process step 49 can be assigned to the operation "Close main clamping force". This means that in this process step 49, the gripper jaws 14, 15 are moved from an open position to a closed position. Process step 50 can be assigned to the operation "Open main clamping force". In this process step 50, the gripper jaws 14, 15 are moved from a closed position to an open position. A process step 51 can also be provided, through which the gripper jaws 14, 15 are moved from a closed position to a partially open position. A process step 51 can be assigned to the operation "Close secondary clamping force". A process step 52 can include the operation "Open secondary clamping force", and a process step 53 can include the operation "Partially open secondary clamping force".

[0047] The following process steps can, for example, be assigned to the storage program 48: process step 50 for opening the gripping device 13 and, if applicable, process step 52 for opening the secondary clamping. Process step 58 can, for example, be assigned to the operation of actuating the ejector 22 or moving the ejector 22 downwards. Process step 59 can be assigned to the operation of raising the ejector 22.

[0048] It is understood that further process steps are assigned to a program 46 and can optionally be integrated into the gripping program 47 and / or the putting-down program 48.

[0049] Starting from these process steps 49, 50..., for example a test program can be created according to Figure 7The system can be configured with the following process steps: Process step 49 is followed by process step 50. Process steps 49 and 50 involve opening and closing the main clamping mechanism and the gripping jaws 14 and 15, respectively. Process steps 49 and 50 can then be repeated. Process steps 51 and 52 then follow consecutively. These process steps 51 and 52 can also be repeated. Process steps 51 and 52 involve actuating the secondary clamping mechanism, i.e., opening and closing the alignment devices 16 and 17. Process step 58 can then be started, followed by process step 59, which involves lowering and then raising the release device 22. These consecutive process steps 58 and 59 can also be repeated.In each of the aforementioned individual process steps, the respective end positions can be additionally queried and verified by at least one pressure sensor 79 and / or at least one sensor element 81. The test program is then terminated, provided the defined parameters have been successfully determined.

[0050] Furthermore, a calibration program 67 can also be used according to Figure 8Such a calibration program 67 is provided for, in particular, after a change between the carrier devices and the laying device 11. This is because the carrier devices may have different pressures in the hydraulic circuit 42. For example, process step 49 can be activated, by which the gripping cylinder 20 closes the gripping jaws 14, 15. In the closed state, the pressure applied in the closed position of the gripping cylinder 20 can be detected by means of the pressure sensor 79. If there is a deviation from a stored pressure in the data processing unit 33, this deviation can be corrected computationally, and thus the data processing unit can be calibrated to the actual acting pressure. A similar process can then be carried out by process step 51 for the alignment cylinder 21 and / or process step 58 for the ejector cylinder 26.

[0051] Furthermore, it can be preferably provided that the data processing unit 33 saves the last called-up program 46 before the control unit 31 is switched off. When the laying device 11 is subsequently started up, the data processing unit 33 can restart the last used program 46 that was saved when it was switched off. This allows the operator of the laying device 11 to immediately resume work and continue from the activities before the interruption or the previous day.

[0052] In Figure 9 A perspective view of a layer of shaped bricks 63 is shown. This layer of shaped bricks 61 comprises several shaped bricks 64 arranged one behind the other to form a row of shaped bricks 65, with several rows of shaped bricks 65 arranged side by side. The layer of shaped bricks 63 is aligned in a so-called fully bonded configuration.

[0053] In Figure 10Figure 11 shows a perspective view of a layer of shaped bricks 63 with shaped bricks in a semi-bonded pattern. The laying device 11 can, within the gripping program 47, start from a layer of shaped bricks 63 according to the figure. Figure 6 The alignment device 16, 17 enables the conversion of the shaped block rows 65 from full bond to semi bond. Alternatively, it can also be seen that the shaped block layer 63 according to Figure 7 in this manner, it is provided at the installation site.
