Definitions

  • the present invention relates to a rock processing machine which has a plurality of different functional units which can be activated from an inactive state to an active state and can be deactivated from an active state to the inactive state at different times, the rock processing machine having an operating console, which is designed to switch the rock processing machine in a start switching process as an operating state switching process from a weaker active operating state to a more active operating state and in a stop switching process as an operating state switching process from a more active operating state to a weaker active operating state to switch, wherein more functional units are activated in the more active operating state than in the less active operating state, wherein the control console has a plurality of status switching elements as switching elements, whereby i each state switching element from the plurality for at least one functional unit is assigned a state transition in such a way that actuation of the state switching element on the functional unit causes a state transition between the inactive state and the active state over an operating state switching process.
  • Such rock processing machines such as those from WO 2019/081186 A are known, for example, are crushing machines for crushing rock material, sieving machines for the grain size-related sorting of granular rock material or combined breaking and sieving machines.
  • the present invention preferably relates to mobile stone processing machines which can reach and leave their place of use in a self-propelled manner. Due to their large weight, mobile stone processing machines are usually crawler-type machines with a crawler chassis.
  • Such stone processing machines - hereinafter also referred to only as “machines” - comprise a plurality of functional units, which are based on have to be activated by a stationary machine in a predetermined sequence in order to finally put the machine in an operational state.
  • switching elements on operating consoles have so far usually been arranged with regard to the available space.
  • Control consoles are known in which, based on an operating state of the machine that has meanwhile been reached, the operator is optically indicated the next switching element to be actuated in the predetermined sequence, for example by lighting up or flashing.
  • Screens on control consoles are also known, which display to the operator the next switching element to be actuated in the predetermined sequence.
  • next switching element to be actuated In order to avoid operating errors beyond the display of the next switching element to be actuated, it is also known to activate only the next switching element to be actuated for an actuation, starting from an operating state reached, while all other switching elements are rendered inoperative. If the operator deviates from the specified sequence of operations, however, it sometimes happens that the machine is considered defective due to the ineffective operation of a switching element that was simply not "on the line", which can lead to an undesirable loss of production.
  • this object is achieved in a rock processing machine of the type mentioned at the outset in that each status switching element from the plurality of status switching elements for at least one functional unit is assigned exactly one status transition.
  • a first set of switching elements is thus formed, which is involved in the start switching process, and a second set of switching elements, which is different from the first, is formed which is involved in the stop switching process.
  • Each set of switching elements is arranged on the control console in a visually and / or haptically perceptible spatial arrangement relationship which corresponds to a predetermined operating sequence of the switching elements of the respective set.
  • a status switching element can therefore be assigned exactly one or more than one functional unit, the activation status of which: active or inactive status, can be changed by actuating the status switching element. For at least one, preferably for each, functional unit that can be switched by the status switching element, however, only one change in status is assigned to the status switching element. If a functional unit is already in the target state of the change of state, actuation of the state switching element has no effect, at least for this functional unit.
  • the first set contains switching elements that are only involved in the start switching process.
  • the second set contains switching elements that are only involved in the stop switching process. These are preferably those status switching elements to which only one change of status is assigned for at least one assigned functional unit, preferably for all assigned functional units.
  • the first and the second set can also have at least one common switching element that is involved in both the start and the stop switching process.
  • the status switching elements are arranged along an optically and / or haptically perceptible actuation sequence path.
  • the actuation sequence and the direction of progress within the same are indicated visually and / or haptically perceptible. Due to the spatial relationship corresponding to the predetermined actuation sequence, the next state switch element to be actuated in the predetermined actuation sequence is arranged spatially closest to each state switch element from the plurality of state switch elements in the direction of progress of the actuation along the actuation sequence path.
  • all switching elements of the start and stop switching processes are arranged one after the other along a common actuation sequence path in the direction of progress.
  • the indication of the state change "beyond an operating state switching process", i.e. beyond the start-switching process or the stop-switching process, is intended to mean that the assessment of the state change is not based on a merely temporary change in the activation state of a functional unit during the operating state. Switching process arrives. It should therefore be irrelevant whether a functional unit - for whatever reasons - is activated and deactivated again, if necessary several times, during the operating state switching process, or vice versa. It is only relevant whether the functional unit after the operating state switching process has a different activation state than before the operating state switching process.
  • the less active operating state can be any desired operating state in which the number of activated functional units is lower than in the more active operating state. Since the start switching process should preferably lead to the establishment of full operational readiness of the rock processing machine, the machine is preferably in full operational readiness in the more active operating state, in which the machine is fully operational as intended or processes rock as intended.
  • the less active operating state can be an operating state of complete machine standstill or can be a stand-by operating state in which basic functional units, such as a control device and a basic power supply of the machine are activated, trade devices for transporting and processing both rock material however, also of waste material released or / and produced during rock processing, such as metal reinforcements, are deactivated.

  • propulsion Chassis and a steering device represent trade devices in the sense of the present application.
  • the second set can also have a third status switching element, the actuation of which deactivates at least one service device.
  • the third status switching element is preferably designed to deactivate the same service devices that were activated by the second status switching element. So that the stop switching process is at least partially an inverted image of the start switching process, which essentially requires the same actuations as the start switching process, only in the opposite order, the second set can have a fourth status switching element, the actuation of which the first energy supply deactivated.
  • the first status switching element is designed to activate not only the first energy supply but at least one further functional unit by its actuation.
  • the exclusive function of activating the first energy supply by the first status switching element is preferred. The same applies mutatis mutandis to the deactivation of at least one further functional unit by the fourth status switching element.
  • the stone processing machine has a plurality of trade devices in order to be able to carry out different tasks of stone processing, such as transport, crushing, sorting, separation, with complex, factual interlinking in one machine.

  • the time sequence can only consist in specifying an activation sequence.
  • the time sequence can also be contain further conditions, such as that a trade device to be activated earlier must first have reported information representing the attainment of its active state to the control device processing the start control command sequence before a trade device to be activated later is activated.
  • a stop control command sequence can be stored in the data memory, which defines the deactivation of a plurality of service devices in a predetermined time sequence. The actuation of the second status switching element then causes the start control command sequence to be carried out. An actuation of the third status switching element causes the stop control command sequence to be carried out.
  • the start control command sequence can, for example, include the activation of the following work devices in the specified order: Impact crusher (crushing work)> fine grain belt (transport)> transfer belt (transport)> return belt (transport)> secondary sieve ( Sorting)> magnetic belt (sorting / transport)> crusher discharge belt (transport)> discharge chute (transport)> pre-screen belt (transport)> pre-screen (sorting)> feed chute (transport).
  • the stop control command sequence can include the deactivation of all of the above-mentioned service devices, for example, in the following sequence: feed chute> pre-screen> impact crusher> pre-screen belt> discharge chute> crusher discharge belt> magnetic belt> final screen> transfer belt> return belt> fine-grain belt.
  • the start control command sequence can include the activation of the following trade devices in the specified order: magnetic tape> crusher discharge belt> discharge chute> jaw crusher (crushing plant)> pre-screen belt>pre-screen> feed chute.
  • the sequence of the deactivated service devices in the stop control command sequence can be exemplified here correspond to the reverse sequence of the activated service devices of the start control command sequence.
  • the sequence of deactivation of service devices according to the stop control command sequence can be a mere reversal of the sequence of activation of the same service devices. However, this does not have to be the case.
  • a status switching element is connected to a control device to transmit signals in such a way that actuation of the status switching element triggers a control process in the control device.
  • Safety plays a major role in stone processing machines, which can usually crush several hundred tons of stone per hour.
  • the machine in particular the control console, can therefore have at least one additional status switching element, which, for reasons related to the operational safety of the machine, takes up such a large volume that the space required for its arrangement in the direction of progress of the actuation is in the first Sentence and one more time in the second sentence is not available.
  • This can be the case, for example, with a switching element that must be able to transmit and disconnect a high level of electrical power.
  • Such a switching element can be, for example, an electrical main switch through which a large part of the current or all of the electrical current supplied to the functional units that can be activated at least by the second status switching element flows.
  • a single such switching element must be able to connect and disconnect a circuit.
  • an integration of such an exceptional special status switching element, through the actuation of which a second energy supply can both be activated and deactivated, in the spatial arrangement of the status switching elements based on the actuation sequence can be realized by actuation of the special status switching element is represented as a pseudo-switching element as a pseudo-switching element that is spatially arranged according to the respective actuation sequence, i.e. along the actuation sequence path, both in the first set and in the second set.
  • the pseudo switching element is preferably the only non-physical switching element of both the first and the second set arranged in the actuation sequence path.

  • the first set and the second set of switching elements can have a common control voltage switch, through whose actuation at least a plurality of switching elements of the first and second set can be activated and deactivated for signal transmission when they are actuated.
  • the control voltage switch can preferably be used to shut down the entire machine or to transfer it from standstill to a ready-to-start state. Because of this fundamental importance of the control voltage switch for machine operation, it can preferably only be actuated using an authentication secret.
  • the authentication secret can be stored in a data memory separate from the operating console or can be implemented as a physical secret, for example in the form of a key bit.
  • the control voltage switch is therefore preferably a robust key switch.
  • the machine can have more than one operating mode, for example a production mode, a maintenance mode and possibly a driving mode.
  • the first set can be a selection switching element have, by actuating an operating mode from a plurality of operating modes of the rock processing machine can be selected.
  • the selection switching element is arranged in the spatial relationship after the control voltage switch, since the machine is usually first switched from standstill to a standby state in which the selection switching element is only activated for the transmission of signals. Since, on the other hand, different start and / or stop control command sequences can be stored in the data memory depending on the selected operating mode, the selection switching element is preferably in the spatial arrangement of the first set of switching elements in front of the second status switching element, particularly preferably also, in the spatial arrangement of the first set of switching elements corresponding to the actuation progress arranged in front of the first status switching element. Depending on the number of selectable operating modes, the selection switching element can be, for example, a toggle switch for only two selectable operating modes or a rotary switch for more than three selectable operating modes.
  • the first set can have a confirmation switch element, the actuation of which generally confirms a setting state of the rock processing machine, which is indicated by in the actuation sequence before the confirmation switch element arranged switching elements is determined.
  • the confirmation switching element can put a control device into a predetermined operating state, for example by activating an emergency stop switch, which is often prescribed for safety reasons, and an associated emergency stop circuit, and / or configure a data memory in a predetermined manner , for example by deleting error messages from a previous operating phase from the current main memory or / and writing them to an archive memory.

  • the machine can then be started up again quickly and safely based on the confirmation switching element.
  • the visual and / or haptic perceptibility of the spatial arrangement relationship which reflects the predetermined operating sequence of the switching elements, can be achieved in the simplest case by a mere straight-line linear arrangement of the switching elements, for example all below one another or all next to one another, on a control panel of the control console.
  • Such a simple arrangement requires either a correspondingly large size of the control panel or an arrangement of the switching elements with a correspondingly small distance from one another, which in turn increases the risk of incorrect operation.
  • the optical and / or haptic perception of the predetermined actuation sequence can be achieved with a relatively large distance between the switching elements, with at the same time relatively little space available for the arrangement of the switching elements, in that for a plurality of switching elements it applies that between two following the predetermined actuation sequence Switching elements a visually perceptible directional symbol and / or a haptically perceptible directional physical formation is arranged, wherein the symbol and / or the formation point to the next switching element in the predetermined operating sequence.

  • the special status switching element 76 switches both from “on” to “off” and from “off” to “on”.
  • the special status switching element 76 is therefore assigned two status transitions for the same technical function content, here: electrical power supply, while the first status switching element 74 and the subsequent second status switching element 80 only for each of the switching elements 74 and 80 between inactive and Active-state switchable functional unit is only assigned exactly one change of state.
  • the electrical energy supply activated in the start switching process must be deactivated again in the stop switching process.
  • a realization of these two state transitions by two separate switching elements would, however, not be able to meet the requirement existing for safety reasons or only with an undesirably high effort, according to which the switched electrical power should also flow via the switching element that switches it.
  • the special status switching element 76 is therefore represented both in the first sentence 58 and in the second sentence 60 as a pseudo switching element 78 only by a symbol which indicates to the operator on the control panel 50 that in the operating sequence after the first status switching element 74 the State special switching element 76 is to be operated.
  • the pseudo-switching element 78 is treated and considered as a switching element in the present application.
  • the pseudo switching element 78 or the actuation of the special status switching element 76 is followed in the first set 58 by the second status switching element 80 as the last switching element, again in the form of a pushbutton switch as an example.
  • a start control command sequence which the control device 62 executes when the second status switching element 80 is actuated, is stored in the data memory 64.
  • this start control command sequence exactly one change of state, usually an activation, is assigned to a plurality of functional units and trade devices 14, 16, 22, 34, 36, 38 and 44 over the start switching process.
  • the activation progress of the machine 10 can be output accompanying the actuation of the switching elements of the first set 58, so that the operator recognizes on the control panel 50 when the start switching process has been completed and the machine 10 is ready for operation.
  • directional arrow symbols 82 or directional triangular symbols 84 are arranged between the switching elements.
  • the directional symbols 82 and 84 point, starting from a switching element to be actuated earlier, to the switching element to be actuated next along the actuation sequence 66 after it has been actuated.
  • the symbols 82 and 84 are also designed as haptically perceptible raised formations 86 and 88, respectively.
  • the raised formations 86 and 88 not only support the visual perceptibility of the symbols 82 and 84 by casting shadows, but can also be felt in poor light conditions or when the control panel 52 is very dirty.
  • Switching element 94 is a third status switching element 94, the actuation of which causes a stop control command sequence stored in data memory 64 to be processed by control device 62, as a result of which functional units and service devices 14, 16, 22, 34, 36, stored in the stop control command sequence, 38 and 44 are deactivated in an order stored in the stop control command sequence.
  • the machine 10 After the complete execution of the stop control command sequence, triggered by the actuation of the third state switching element 94, the machine 10 as a rule has the same operating state as before actuation of the second state switching element 80.
  • the stop Control command sequence is merely the reversal of the order of the functional units and trade devices 14, 16, 22, 34, 36, 38 and 44 of the start control command sequence with each associated opposite change of state.
  • the special status switching element 76 is to be actuated again. Since it is in the on-state after the start switching operation, the actuation of the switching element 76 means a switching actuation in the off-state.
  • the actuation of the special status switching element 76 and thus the deactivation of the electrical power supply of the assigned functional units and service devices follows in the actuation sequence along the actuation sequence path 66, a fourth status switching element 96, which deactivates the diesel engine 16.
  • the last actuation in the stop switching process is the actuation of the control voltage switch 68 and the removal of the key necessary for its actuation.
  • the sequence of actuation of the switching elements 94, 78, 96 and 68 of the second set 60 is in turn indicated by directional arrow symbols 98 and directional triangular symbols 100, depending on the space available, between the switching elements of the second set 60.
  • the arrow symbols are 98 and the triangle symbols 100 also raised formations 102 or 104, which can still be felt in poor light conditions and / or heavy soiling, although they may no longer be recognizable due to their coloring alone.
  • the different hatching of the directional symbols and formations 82 to 88 of the first set 58 on the one hand and of the directional symbols and formations 98 to 104 of the second set 60 on the other hand in FIG Figure 2 indicate that the directional symbols and formations 82 to 88 of the first set 58 have a different color and / or a different haptically detectable texture than the directional symbols and formations 98 to 104 of the second set 60 for better differentiation.
  • the directional symbol 90 which is at the same time the directional formation 92 also differs from the symbols and formations of the first and second sets 58, 60 in terms of color and / or texture, since the symbol 90 or the formation 92 neither only in the first nor only in the second set 58 , 60 listened.
  • the emergency stop switch 56 If the intended operation of the machine 10 is initially terminated by the emergency stop switch 56, no renewed actuation of the control voltage switch 68 and, as a rule, no actuation of the selector switching element 70 are necessary to restart the machine 10.
  • the emergency stop switch 56 which is usually mechanically blocked after actuation, is released, the operation of the machine can be restored with a start procedure which begins with the confirmation switch element 72 as the first switch element to be actuated.
  • the control device 62 is designed to highlight this switching element by illuminating the switching element to be actuated next in an operating state switching process and to display it to the operator.
  • status switching elements 80 and 94 on the one hand and on the control panel 52 74 and 96 on the other hand which are each assigned to the same functional units, but with opposite changes in state, arranged one below the other in columns, while - with the exception of the control voltage switch 68 - all switching elements 70 to 80 of the start switching process and all switching elements 94, 78 and 96 of the stop switching process are arranged in rows next to one another in different lines.
  • this arrangement can also be interchanged in terms of rows and columns.
