    Description The present invention relates to a portable tool for machining a workpiece according to the preamble of claim 1 and to a method for replacing an accumulator of a portable tool according to the preamble of claim 6.
    Conventionally used accumulator-driven tools have at least one accumulator or battery, which supplies an electric motor with electrical energy, so that it can set in motion or drive the components used for performing a work.
    In the case of constructively simple challenge tools, which do not have a control device for controlling and regulating various consumption units, such as a food and / or analysis device for determining the tool's challenge or accomplished performance or work, a replacement of the accumulator or battery is unproblematic, since the use of the tool can continue immediately after the insertion of the new and the charged accumulator, respectively.
    This is different with, for example, accumulator-driven tools which have a control device which, for example with an accumulator-driven screwdriver, regulates and controls the torque or speed of the screw head and monitors the torque or speed with the aid of suitable feed devices. In the case of these tools, the control device is deactivated or switched off when the, for example, the discharged accumulator is removed from the tool, whereby the operating system and specific software of the control device, respectively, are interrupted. After inserting the new and charged accumulator into the tool, the control device must then be reactivated or switched on, whereby the operating system is booted or reactivated or restarted.
    Since the start-up of the operating system takes a certain amount of time, within this time period no machining of any workpiece with the tool aga rum takes place. As a result, the cycle time for machining a workpiece is substantially required, especially in the case of tools in which a frequent accumulator change is necessary.
    Thus, it is an object of the present invention to provide a portable and accumulator-driven tool for machining a workpiece and a corresponding method, which dials after replacement of an accumulator in activated operating system and in activated software, respectively.
    This object solves the present invention by means of a portable tool according to claim 1 and by a method according to claim 6. Particular embodiments and further developments are apparent from the dependent claims.
    Thus, the claims relate to a portable tool for machining a workpiece, in particular for mounting screws / bolts in the workpiece, the tool having at least one drive device for driving a work head or at least one element of a drive head, for example a drive shaft, at least one accumulator to provide electrical energy, at least one control device with an operating system for controlling and / or controlling processing parameters, at least one storage device for storing processing data and at least sanding and receiving device for sanding and / or receiving said processing data.
    The tool according to the invention furthermore has at least one substantially electrical element which at least short-term storage of electrical energy, which enables a replacement of the accumulator when the operating system is activated.
    In fact, the portable and mobile tools, respectively, preferably have an electric motor, which is supplied with electrical energy by an accumulator or a battery, so that no electric cable negatively impairs the tool's mobility.
    As a result, the tool according to the invention is freely movable, in order to preferably reach all the working areas of a workpiece, in order to be able to process it properly. Due to the lack of an electric cable, the risk of the workpiece or its surfaces being damaged by the cable or any connections of the cable is also excluded. At the same time, the safety of the operator and the user, respectively, is increased, which could easily be damaged by defective electrical cables and could easily trip on surrounding cables. The electric motor itself preferably serves to drive a working head or a part thereof, for example a grinding wheel or a screwdriver.
    The accumulator can also, for example, also provide electrical energy for a control device, which, among other things, serves to control and / or regulate machining parameters, for example the number of machining steps to be performed or the speed and / or torque of a screwdriver. Thus, the control device advantageously monitors each machining step performed by the tool and consequently compares the BOR value of the machining with the AR value of the machining, in order to identify an incorrect machining and, if necessary, announce it to the user.
    Machining data, which announces to the tool how to process a particular workpiece, is advantageously transmitted to the tool from a central control device. Thus, the tool has a sanding and receiving device, which, for example, receives this BOR processing data. The sanding and receiving device is thus a device assigned to the control device or an independently functioning device.
    BOR machining data, i.e. machining data which are transmitted or transmitted from the central control device to the tool and preferably to the sanding and receiving device of the tool, contain, for example, the machining parameters necessary for machining, for example a BOR speed and / or a BOR torque. It is thus conceivable that, for example with the aid of a data device arranged on the tool or connected to the tool, a bar code, which is located on the tool, is read or registered to thereby identify the workpiece to be machined. The information determined from the bar code is then forwarded via the sanding and receiving device to the central control device, in order thereby to obtain the necessary processing data.
    The central control device determines, for example, from the data transmitted by the tool sanding and receiving device the part number of the workpiece and preferably the corresponding machining assignment and the assignment number and thus the machining parameters required for machining, for example the required torque when screwing in a screw.
    The machining data selected by the central control device are sent to the tool and preferably to the sanding and receiving device of the tool. Thus, the control device of the tool obtains all for the processing of the present and unloaded necessary processing data of the workpiece and consequently preferably aleat after machining steps in the corresponding value for the machining of the tool.
    With the aid of a camera or an image recording device, for example, a detection of the current machining position on the workpiece is possible, so that the control device with the aid of an image comparison with image data stored in the storage device enables an identification of the current machining position on the workpiece. Thereby it is possible for the control device to set the machining parameters for the working head alit according to the detected machining position.
    With the aid of this image recording device an identification of the workpiece is also conceivable, which would thereby replace a bar code reader, so that only one device would be used on the tool, which in addition to identifying the workpiece for retrieving machining data also detected the individual machining positions of the tool.
    It is also conceivable that the processing data required for processing the workpiece, the so-called Boron processing data, are already stored in the tool storage device, so that only an identification of the workpiece must allow space to determine or read from the storage device necessary data for processing. A connection with the central control device is in this case no longer compellingly necessary, so that the user 5N / en can continue the machining of the workpiece with the aid of the tool in the event of a connection failure of the preferably radio-connecting connection.
    Preferably, during machining of the workpiece, the tool substantially continuously controls and records the machining process and consequently determines the current AR machining data. It should be noted that, for example, in the case of an accumulator screwdriver, the current torque and the current speed, respectively, are determined and compared with the BOR machining parameters for this defined machining position. If the AR machining parameters do not match the BOR machining parameters, there is the possibility that the tool warns the operator and the user via, for example, an acoustic or visual signal. Thus, the tool preferably has corresponding lighting and / or loudspeaker devices.
    The machining data or machining parameters determined by the tool, i.e. the AR machining parameters, are preferably stored at least briefly in the tool storage device in such a way that, for example, each BOR machining parameter is assigned an AR machining parameter. All registered AR machining parameters are preferably assigned the registered article number and, where applicable, a corresponding assignment number or workpiece number, so that a reading of the occurring AR machining parameter to the corresponding workpiece data is possible.
    In a preferred embodiment, the AR machining data set and the AR machining data, respectively, are then transmitted from the tool and preferably from the tool's sanding and receiving device to the central control device, for example to be loaded into a reproducible analysis program. In this way, the operator and the user, respectively, receive the opportunity to carry out, for example, a quality analysis or to save back the machining quality of individual machined workpieces.
    By determining the machining data and the machining parameters for the machining and a monitoring of these AR machining parameters by a comparison with the BOR machining parameters and machining data, the occurrence of incorrect machining of a workpiece by an operator is prevented, even at very high processing complexity. a plurality of successive machining steps and at a plurality of different workpieces.
    In addition to the drive device, i.e. the electric motor for driving a working head, and the unloading device and / or image recording device and the control device and / or the storage device and / or the sanding and receiving device, which are also a control device subordinate or a relatively independent control device, the accumulator can also supply for example further at least one feeding device and / or at least one recording device with electrical energy.
    The feeding device is, for example, a device for feeding AR machining parameters, such as a torque or a speed at, for example, a screwdriver.
    The recording device, on the other hand, establishes, for example, a screw-in angle between the screw / bolt to be screwed in and the workpiece, in order to prevent an oblique screw-in and armed wedging of the screw / bolt in the passage.
    The feeding device and the recording device, just like the unloading device and the image processing device or the lighting device or the loudspeaker device, etc., thus preferably constitute consumption units of the tool, all of which are supplied with the electric energy of the accumulator.
    Should a replacement of the accumulator of the tool now become necessary, the control device on which the operating system operates is preferably preferred, as well as the continued supply of electrical energy, in order to prevent the operating system from being shut down.
    To this end, the tool according to the invention preferably has an electrical element which can store electrical energy for at least a short period of time.
    In a preferred embodiment, this electrical element is a capacitor, particularly preferably an electrolyte capacitor.
    However, it is also conceivable for the electrical element to be an additional accumulator or a battery in which, even during the replacement of the accumulator or the main accumulator, it can supply, for example, the control device with current and electrical energy, respectively.
    Advantageously, however, a capacitor is provided as an electrical element in the tool, which is preferably an accumulator-driven hand screwdriver, since a capacitor in comparison with an accumulator or a bat can certainly only provide electrical energy for a limited period of time but is essentially unlimitedly rechargeable and rechargeable. Thus, the capacitor has a very long service life.
    The capacitor is preferably charged continuously during operation of the tool. However, it is also conceivable for the capacitor to be charged at the request of the control device. Such a prompt is given to the control device, for example, when the accumulator signals the control device that the next one is discharged. Furthermore, it is possible that the prompt to charge the capacitor intraphi first when, for example, an identification device, which is a device which is subordinate to the control device or a device which is independent of the control device, identifies a removal of the accumulator by activating a tripping mechanism, such as a switch. or deactivated, causing a charge of the capacitor.
    The identification of the removal of the accumulator can take place, for example, by opening a protective cap of the housing. When a connection (electrical or mechanical) between the protective cap of the tool and the tool is broken, the identification device identifies the opening of the protective cap and thus the intention of removing the accumulator.
    It is also conceivable for the operator to press, for example, a suitable orifice or button, in order to signal the removal of the accumulator to the control device and preferably the identification device, whereby appropriate procedure steps, such as a charging of the capacitor, are triggered.
    Preferably, the control device is computer-technically connected to the consumable units of the tool for deactivating the consumable units upon a removal of the accumulator from the tool.
    That is, the control device is connected to the consumption units, such as the feeding device, the unloading device or the sanding and receiving device and the storage device, unless these are devices which are subordinate to the control device, by means of a data cable, to cause a deactivation thereof in an identification of a removal of the accumulator.
    It is also possible that the control device is also connected to suitable switching elements, which if necessary can separate the consumption units from the accumulator and preferably from the electrical element, i.e. the capacitor. Consequently, when identifying a replacement of the accumulator, the control device activates these switching devices, the consumption units being separated from the supply of electrical energy, i.e. from the accumulator and the capacitor, by the switching units opening, for example, in order to prevent a current flow to the consumption unit.
    Preferably, only the control device is connected to the electrical element for supplying electrical energy even during the replacement of the accumulator.
    For example, the electrical connection between the electrical element and the control device is preferably not broken during the replacement process of the accumulator. Thus, a shutdown of the operating system is preferably not necessary during the replacement of the accumulator, since the control device does not have to be completely switched off or deactivated.
    As a result, the operating system must not be restarted or booted after the insertion of a new or charged accumulator, whereby no precious time for machining a workpiece is lost, but machining can be resumed immediately.
    Accordingly, the claims also relate to a method of replacing an accumulator of a portable tool for machining workpieces, the tool having at least one drive device for driving a working head, at least one accumulator for supplying electrical energy, at least one control device with an operating system for control and / or controlling machining parameters, at least one storage device for storing machining data and at least one sanding and receiving device for sanding and receiving said machining data, with the following steps: a) identifying a removal of the accumulator from the tool by means of the tool control device; b) interrupting a transfer of machining data from a central control device to the tool sanding and receiving device by means of the control device; c) continuing the control device in a state of emergency operation and d) supplying the control device with electrical energy from the electrical element during the replacement of the accumulator.
    Consequently, upon removal of an accumulator from a tool, which is preferably an accumulator-driven and mobile hand-held screwdriver, the removal of the accumulator is preferably identified by means of an identification device.
    For example, a light curtain can also be arranged on the accumulator or on a protective cap, which delimits the accumulator from the surroundings, that the light curtain is broken when the protective cap is opened or when the accumulator is removed, a signal transmitted to the tool control device indicating removal of the accumulator.
    After the removal of the accumulator has been identified, the transfer of BOR and / or AR processing data from a central control device to the tool and preferably to the tool sanding and receiving device and preferably from the tool and preferably from the tool sanding and receiving device to the central control device is advantageously interrupted. data loss and the energy-intensive sanding and reception of data, thereby reducing the electrical energy present during the accumulator change.
    Thus, the transmission and consequently the preferably wireless radio connection is continued in the power-saving idle state (idle mode), in which the connection between the central control device and the tool and the tool's sanding and receiving device is maintained, but no data exchange can take place.
    This avoids a time-consuming renewed connection or a time-consuming renewed re-establishment of the radio connection between the central control device and the tool or the sanding and receiving device of the tool after insertion of a new and a charged accumulator, respectively.
    In addition, the control device of the tool itself is continued in a standby operating state, i.e. in standby mode, whereby the operating system of the control device is not shut down and consequently after an activation of the control device also does not have to be booted or started up again.
    As a result, the further use of the tool can take place immediately after the replacement of the accumulator without delay.
    The control device is thus preferably the only device or unit of the tool which is supplied with electrical energy during the replacement of the accumulator, in order to avoid a shutdown of the operating system. For this purpose, during the replacement of the accumulator, the control device preferably receives electrical energy from the capacitor or an additional accumulator or a bat.
    In a preferred embodiment, when removing the accumulator from the tool, at least one consumption unit connected to the accumulator is deactivated by the tool with the aid of the control device.
    In a further preferred embodiment, with the aid of the control device, all consumption units are deactivated when the accumulator is removed from the tool, so preferably only the control device itself, which, however, is in a current and energy-saving emergency mode, must be supplied with electrical energy.
    It is said that, for example, any feeding devices or recording devices or the storage device and / or the sanding and receiving device, insofar as these do not constitute devices coordinated or subordinate with the control unit, are switched off or deactivated, so that during consumption of the accumulator no longer need their business necessary electrical energy.
    If, for example, the storage device and / or the sanding and receiving device are coordinated with the control device and subordinate devices, then these are preferably continued with the control device in a current-saving resting layer, in which for example the storage unit can no longer store processing data and the sanding and receiving device can no longer sand and / or receive processing data. Only the radio connection between the sanding and receiving device and the central control device is maintained, however, without performing exchange or forwarding of data, respectively.
    Preferably, from the central storage unit to the tool, overhead processing data is stored in the tool storage device until the replacement of the accumulator upon identification of the removal of the accumulator from the tool.
    Consequently, for example, all machining data is stored, which, for example, contains information concerning the workpiece to be machined and which sands from the central control device to the tool and preferably to the tool sanding and receiving device may perform the machining of the workpiece, first in the storage unit. non-volatile memory of the tool when, for example, an identification device or the tool control device identifies the removal of the accumulator.
    It is said that during the operation or use of the tool the processing data transferred from the central control device to the tool is temporarily stored, it is said that DRILL processing data, preferably in a volatile memory, for example a working memory, to provide the necessary information to the tool controller. individual machining steps for the workpiece are available, so that the control device can set the individual components for the machining of the workpiece using the components and the drives or the electric motors according to the machining data and monitor their design.
    Thus, in a preferred embodiment, the processing data listed by the tool is stored until the replacement of the accumulator in the tool storage device, upon identification of removal of the accumulator from the tool.
    That is, the tool's control device by monitoring the tool's work heads and components, which serve for machining the workpiece, established machining data and machining parameters, i.e. AR machining data and AR machining parameters, are preferably stored in the storage device and the non-volatile memory of the tool, respectively. of the accumulator and the planned removal of the accumulator.
    However, it is also conceivable that the processing data transmitted from the central storage device to the tool and / or the processing data marked by the tool are substantially continuously stored in the tool storage device during use of the tool.
    This stores BOR machining data, i.e. the machining data which is sent from the central control device to the tool and preferably to the tool sanding and receiving device, as well as the AR machining data and the AR machining parameters, which are recorded and determined by the control device or preferably the feed device. during the machining of the workpiece by the monitoring of the work heads and the components which serve for the machining of the workpiece, essentially immediately in the storage device and in the non-volatile memory of the tool, respectively.
    Thereby, an intermediate storage of the AR and / or BOR processing data and the AR processing parameters, respectively, is output in a volatile memory, for example the working memory.
    In a preferred embodiment, the processing data transmitted from the central storage device to the tool and the transmission of registered processing data from the tool to the central control device takes place via a wireless radio connection.
    Thus, not only does the central control device transmit BOR processing data via a wireless radio connection, such as Bluetooth, to the tool or tool sanding and receiving device, but also the tool transmits the established AR processing parameters in connection with AR processing data using the sanding and receiving device. the central control device.
    The data transmitted by the tool is preferably stored in a storage device of the central control device and supplied, for example, with a database system or an analysis tool or an analysis software, by means of which an array of the Ar machining parameters for a particular workpiece is processed with a particular tool. saga AR processing data), possible.
    With the help of these preferably long-stored AR processing data, it is possible for the operator or another person to carry out a quality analysis of the tool and of the processing process, respectively.
    Further advantages, features and features of the present invention will become apparent from the following description of the accompanying drawings, in which, by way of example, an embodiment of the tool according to the invention and an electronic circuit diagram for an embodiment of the tool according to the invention are shown.
    Components which in the figures correspond at least substantially as far as their function is concerned can in this case be denoted by the same male reference numerals, these components not having to be denoted and explained in all the figures.
    In the figures: figure 1 shows a principle sketch of an embodiment of the tool according to the invention; and figure 2 is a schematic diagram of a block wiring diagram for an embodiment of the tool according to the invention.
    Figure 1 shows a schematic diagram of an embodiment of the tool 1 according to the invention, which has an electrical element 2 for storage and buffering of electrical energy and of electric current, respectively, so that in the exchange process of the main accumulator 3 or the accumulator 3, which supplies or feeds an electric motor 4 with electrical energy, at least briefly supply a control device 5 with electrical energy, so that an operating system operating at the control device does not have to be shut down and consequently this operating system does not have to be started up or booted again after the introduction of a new and charged accumulator 3.
    The control device 5 is a component of a control and display unit 9, which furthermore preferably has a display device 7, such as a display screen 7, an input device 8, such as a keypad 8 and a sanding and receiving device 6, such as a radio module 6.
    With the aid of the input device 8, for example, program data or processing data can be entered and transmitted to the control device 5. The input of said data and input data is then disabled for the operator or user via the display device 7. However, with the aid of this display device 7 even currently processed processing parameters can be visualized. for example, the speed of the electric motor 4, which directly affects the speed of the working head 11 located in the angle head 10 and the machining component 11, respectively, which is driven by the electric motor 4.
    For recording such processing parameters, for example, a first feed device 12, such as an angle sensor 12, is arranged on the electric motor 4 or connected thereto, that preferably via suitable sensors the rotation angle has the rotor and / or the rotation angle of the shaft driven by the rotor has the electric motor 4 can be registered or controlled or its change relative to a stationary part can be registered or controlled.
    With the aid of a second feed device 12.2, such as a feed shaft 12.2 or a feed electronics 12.2, the torque can preferably be fed to the shaft driven by the rotor of the electric motor 4 or fixed, whereby a conclusion concerning a torque has the working head 11 can be drawn.
    Between the electric motor 4 and the second feed device 12.2 a gear ratio 13 is arranged, by means of which the movements and the torque, which acts on the shaft, can be changed, so that the hand-held screwdriver, which has been damaged in Figure 1, or the accumulator-driven hand-held screwdriver device. screw a screw into a workpiece and unscrew it.
    A drive electronics 14, which is arranged on the accumulator 3 so that it is supplied with electrical energy, controls and regulates the drive of the electric motor 4, in order to maneuver the working head 11 alit according to the course of a program and alit according to processing data and processing parameters stored in the control device 5.
    It can be said that when, for example, the control device 5 is informed via the overdue processing data, that in the case of processing steps "eft", for example, an M16 screw is to be screwed into a corresponding gangway with a defined speed, the control device 5 sends this data to the drive electronics 14, which installs the motor 4 and preferably also the gear unit 13 said that this M16 screw can be screwed in at the predetermined speed.
    Thereby, a preferably wired first preferably two-part line 15 or supply line 15 exists between the control device 5 and the drive electronics 14 and the accumulator 3, respectively, for transmitting, for example, relevant data, signals and / or information from the control device 5 to the drive electronics 14 and also supplying electrical energy from the accumulator. 3 at the disposal of the control device 5. Thereby, the first two-part line 15 has a data line for transmitting said data and / or the signals from the control device 5 to the drive electronics and a power line for transmitting electrical energy to the accumulator 3 to the control device 5.
    As a result, there is also a preferably wired second preferably two-part line 16 or line 16 between the drive electronics 14 and the accumulator 3 and the electric motor 4 and the angle sensor 12, respectively, to control and regulate the electric motor 4 in accordance with the processing data present in the control device 5 and supply it and the angle sensor 12 electrical energy from the accumulator 3.
    A third preferably wired two-part line 17 or supply line 17 is present between the control device 5 and the electrical element 2, which is preferably a capacitor 2 or a buffer capacitor 2. Thereby it is possible to control the capacitor 2 s5 when the accumulator 3 is removed. a charge, the capacitor 2 therefore having to be preferably connected to the accumulator 3 via an electrical line (not shown).
    In addition, it preferably consists of a data line and a power line consisting of the line 17, the flow of a current from the capacitor 2 to the control device 5, when the accumulator 3, which is preferably used for supplying electrical energy, is replaced. Thus, the control device 5 must not be completely switched off, the titanium can switch to a standby operation, it will switch to a standby operating state, so that the operating system installed on the control device 5 does not have to be shut down.
    Between the second feed device 12.2, the viii saw shaft 12.2 and the feed electronics 12.2 and the control device 5, there is preferably also a connection 18 and a data line 18, respectively, for transmitting data and / or signals, so that a substantially continuous data exchange can take place between the control device 5 and the second feeding device 12.2. As a result, the second feeding device 12.2 can substantially continuously transmit the food processing parameters recorded therefrom to the control device 5, respectively, which is preferably compared to those with shaving processing parameters stored in the preferably integrated storage device (not shown) by means of an integrated comparison device (not shown). if necessary, adjust the movements of the working head by, for example, a renewed installation of the speed.
    The individual devices, such as the control device 5, the display device 7, the input device 8, the radio device 6 and the radio module 6, the first 12 and the second power device 12.2, the drive electronics 14, the electric motor 4 and / or the gear 13 are supplied with electrical energy and current from the accumulator 3 for to fulfill their functions and to carry out their work. For this purpose, the individual devices listed above are connected to the accumulator 3 via electric power lines (not shown).
    A housing 19 surrounds the entire steering and the controlled drives, which protects them from soiling and magnification and damage, respectively.
    The transmission of processing data and the corresponding processing parameters preferably takes place via a wireless radio connection, such as Bluetooth or WLAN, from a central control device 20, such as a central computer 20, which is preferably via a wired line 21, such as a LAN line. is connected to a radio access point 22 (access point).
    With this radio access point 22, the radio module 6 of the tool 1 establishes a radio connection 23, in order to receive BOR processing data from the central computer 20 and store it in the control device 5 and preferably the storage device of the control device 5.
    On the one hand, the radio module 6 can transmit the determined AR processing data via this radio connection 23 to the central computer 20, which are preferably stored at least briefly in the control device 5 and there preferably in the storage device.
    Thereby, the user can later perform a quality analysis in the central computer 20 concerning the tool 1 and the workpiece machined by the tool 1 (not shown).
    In Figure 2, a schematic diagram of a block circuit diagram 50 for an embodiment of the tool according to the invention is neutralized. It is clear that the accumulator 3 is connected to the drive electronics 14 or the start switch 14 via a positive connecting line 30 or positive current line 30 and a negative connecting line 31 or negative current line 31.
    Consequently, a power line or an electrical energy line is first released for conducting electrical energy from the accumulator 3 to the appropriate devices, when the start switch 14 is activated, i.e. the tool is switched on, and consequently the drive electronics are started 14.
    As a result, the drive electronics 14 and the start switch 14, respectively, are connected to the electric motor 4 via corresponding electrical lines 32, 33, 34, to conduct the electrical energy required by the electric motor 4 upon activation of the start switch 14 from the accumulator 3 to the electric motor 4, and at a deactivation. of the start switch 14 disconnect the line of electrical energy from the accumulator 3 to the electric motor 4.
    A switching element 36, which converts, for example, an unstabilized input DC or input shaft voltage to a DC voltage at another defined level, is connected via a positive electrical line 35 (positive pole) or a positive supply line 35 to the drive electronics 14 or the start switch 14, in order to activation of the start switch, an electrical energy is supplied from the accumulator 3.
    After the conversion of the input voltage which enters the switching power supply 36, the electrical energy originating from the accumulator 36 is discharged from this accumulator via a further electrical line 37 and a further electrical supply line 37 via a monitoring controller 38 to the control device 5 and the control and display unit 9, respectively, which contains the control device, the display device, the input device and the sanding and receiving device and the radio module, respectively.
    Said monitoring controls 38 preferably have a switching unit 38a or an electrical switch 38a, by means of which switching can take place between an accumulator drive and a buffer drive. It is said that when the accumulator, as a result of an exchange thereof or as a result thereof, the tower can no longer supply electrical energy to the control and display unit 9 and preferably the control unit 5, the switching unit 38a of said monitoring controls 38 switches, the viii said switch slat if an electrical switching circuit is established with the buffer element 2 or the electrical element 2 or the buffer capacitor 2 or the capacitor 2.
    This capacitor 2 is consequently connected via a positive electrical line 39 or positive supply line 39 to a charging electronics 40, which is connected in parallel with said monitoring controls 38. By means of this charging electronics 40, the capacitor 2 is preferably charged continuously during operation of the tool. However, it is also conceivable that the charging electronics 40 allow a charge of the capacitor 2 only when it receives a signal from the control device 5. This signal is emitted when, for example, a replacement or a planned replacement of the accumulator is identified by the control device, or the control device 5 registers a very low battery level. the accumulator 3, s5 that it can be assumed that this must be replaced within a short time.
    If now the switching unit 38a is switched on or switched off so that the electrical connection between the supply line 37 and the control and display unit 9 is broken and a renewed electrical connection between the capacitor 2 and the control and display unit 9 is established, consequently said monitoring controls 38 switch from an accumulator operation to a buffered rift.
    As a result, the control and display unit 9 is now supplied only with electrical energy from the capacitor 2 and a replacement of the accumulator 3 is possible, without the control and display unit 9 and preferably the control device 5 of the control and display unit 9 having to be shut down.
    By means of a transfer device 41 or a data transfer line 41, the first 12 and / or the second supply device 12.2 is connected to the control and display unit 9 and in particular the control device 5 of the control and display unit 9, in order to receive data and / or signals from the control device. 5 or send to it.
