Description

Technical Field

[0001] This disclosure relates to a riveting device for rivet bolts and rivet nuts, and particularly to a method for operating this riveting device. Background Technology

[0002] Common riveting devices for bolts and nuts typically feature a rivet mandrel with dual functions. On one hand, the rivet mandrel is used to upset the rivet body of the bolt or nut, thereby creating the upset head. For this purpose, the rivet mandrel can move in a translational manner along its axis of action. The upset of the rivet body is performed by the rivet mandrel executing a stroke along the axis of action. This stroke is often referred to as the set-up stroke. Furthermore, the rivet mandrel is rotatable about its axis of action and has threads. This allows the bolt or nut to be automatically screwed onto the rivet mandrel, where the threads of the rivet mandrel and the bolt or nut are tightened, thereby creating the connection required for upseting the rivet body.

[0003] The riveting device of this type described herein is described in EP0670199A1. In this riveting device, the rivet mandrel is linked to a drive motor via a ball screw drive of a first transmission system, so that the rivet mandrel moves in a translating manner along the axis of action. In order to enable the rivet mandrel to perform translational movement and thereby to be tightened, a second transmission system and a disengageable clutch device are provided.

[0004] The riveting device described in EP0670199A1 is designed to switch to the first drive system via a clutch mechanism of the second drive system. Although the rivet mandrel rotates via the second drive system, the first drive system needs to be linked with the drive motor to transmit force from the drive motor to the second drive system. Therefore, when tightening is performed, the threaded shaft of the ball screw drive in this riveting device undergoes translational motion. The trade-off is additional structural space, particularly axial structural space, which is needed for the conventional workflow: first tightening the rivet bolt or nut onto the rivet mandrel and then installing it onto the workpiece.

[0005] In this context, it becomes apparent that a technological prerequisite needs to be created so that tightening can be performed, at least independently of the transmission system responsible for the translational movement of the rivet mandrel. The expectation is that this decoupling will allow for a more compact structure of the riveting device, particularly in the axial direction. Summary of the Invention

[0006] A riveting device is proposed, comprising a rivet nozzle and a rivet mandrel for riveting bolts or nuts, the rivet mandrel being configured to move relative to the rivet nozzle along an axis of action to perform an installation stroke and to move about the axis of action for tightening. The riveting device includes a first transmission system for moving the rivet mandrel along the axis of action and a second transmission system for moving the rivet mandrel about the axis of action. The riveting device also includes a housing and a motor (preferably located within the housing) for driving the rivet mandrel via the transmission system (i.e., via the first and / or second transmission systems).

[0007] In order to enable tightening in a manner decoupled from the first transmission system, a planetary transmission is provided in the proposed riveting device. The planetary transmission preferably has at least three transmission members, wherein the first transmission member is assigned to the first transmission system, the second transmission member is assigned to the second transmission system, and the third transmission member is operatively connected to the motor, particularly rotatably and fixedly connected to the output shaft of the motor.

[0008] The term "planetary transmission" in this disclosure is specifically understood to mean a transmission device having a plurality of, particularly at least three, transmission elements, wherein at least two of the transmission elements are arranged concentrically with respect to a common axis of rotation. In particular, at least two, preferably at least three, transmission elements are configured to rotate about a common axis of rotation. In this disclosure, the terms "planetary transmission" and "planetary gear transmission" can be understood as synonyms.

[0009] These transmission components, for example, include at least a hollow component (particularly a hollow gear ring), an inner component (particularly an internal gear) disposed within the hollow component, and at least one intermediate component disposed between the hollow component and the inner component. The intermediate component makes kinetic contact with the inner component on one hand (particularly radially inward) and with the hollow component on the other hand (particularly radially outward), and in particular serves to transmit rotational motion. For example, the intermediate component is configured to make kinetic contact with both the inner component and the hollow component through its outer periphery. The intermediate component may also be configured to make kinetic contact with the hollow component through its outer periphery and with the inner component through its inner periphery. For example, in this case, the intermediate component is annular and / or arranged concentrically with the hollow component and the inner component.

[0010] The term "planetary transmission" also includes, for example, a wellgetriebe, which has, for example, a wave generator, a flexspline, and a circular spline as transmission elements. The term "planetary transmission" also includes, for example, a cycloidal transmission, which has, for example, at least an eccentric element (especially an eccentric shaft), a spool, rollers engaged in the spool, and radially externally distributed bolts arranged in a circular configuration as transmission elements.

[0011] One embodiment of the proposed riveting device provides a screwing mechanism decoupled from a first drive system, wherein the planetary drive is configured for use in dual-axis operation, in which the first or second drive element selectively drives the corresponding drive system.

[0012] The proposed riveting device can be configured in this embodiment such that the first and second transmission members can rotate relative to the device housing in the driven state and can enter a non-driven state via at least one switching element. In the non-driven state, there is a rotationally fixed connection relative to the device housing, particularly a rotationally fixed connection with the device housing. This facilitates a technically simple design, allowing for switching of driving action back and forth between the first and second transmission members.

[0013] The proposed riveting device can also be configured such that the first and second transmission members are rotatably fixed to the device housing via a switching element in a non-driving state, and this rotatably fixed connection is released in a driving state. For this purpose, the switching element can be configured to switch between a first switching position and a second switching position, wherein in the first switching position the first transmission member is in a driving state and the second transmission member is in a non-driving state, and in the second switching position the first transmission member is in a non-driving state and the second transmission member is in a driving state.

[0014] Alternatively, at least two switching elements can be provided. For example, in this case, one switching element is assigned to the first transmission member and the other switching element is assigned to the second transmission member, and the switching elements are preferably configured to switch between two switching positions, wherein the transmission member corresponding to one switching position is in a driven state and the transmission member corresponding to the other switching position is in a non-driven state.

[0015] At least one switching element can be a mechanical (especially purely mechanical) switching element. At least one switching element can also be an electromechanical switching element, such as an electromagnetic switching element. In particular, at least one switching element is a form-fitting switching element, which is, for example, in a form-fitting connection in at least one switching position. For example, a form-fitting switching element creates a form-fitting connection between the device housing and the corresponding transmission element. The switching element can be a component of the switching device. The switching element itself can also be or form part of the switching device.

[0016] The proposed riveting device preferably has a mandrel receiver for the rivet mandrel. The mandrel receiver is specifically configured to displace along the axis of action. In one embodiment, the mandrel receiver is connected to the rivet mandrel in an anti-slip manner, wherein the rivet mandrel is received in a manner rotatable within the mandrel receiver. Thus, the first and second transmission systems can act independently of each other on the rivet mandrel. Further measures are taken in this regard to enable tightening to be performed independently of the first transmission system.

[0017] The connection between the mandrel receiver and the rivet mandrel in an anti-slip manner is specifically understood to mean that an anti-slip connection exists at least during the installation stroke of the rivet mandrel. It is also understood to mean that an anti-slip connection exists at least in the direction along the axis of action, thereby causing the installation stroke of the rivet mandrel through the translational movement of the mandrel receiver.

[0018] The proposed riveting device can be designed such that the first transmission system includes a shaft drive, particularly a ball screw drive, which preferably has a shaft nut on the drive side and a threaded shaft on the output side. The threaded shaft is connected to the rivet mandrel in an anti-slip manner and is configured to move along the axis of action. This facilitates a technically simple design to convert the rotational motion of the output shaft into a translational drive motion, which causes the rivet mandrel to move along the axis of action. For example, the threaded shaft is connected to the rivet mandrel in an anti-slip manner via the aforementioned mandrel receiving member.

[0019] The anti-slip connection between the threaded shaft and the rivet mandrel is specifically understood as the existence of an anti-slip connection at least during the installation stroke of the rivet mandrel. It should also be understood that the anti-slip connection exists at least along the axis of action, such that the translational movement of the threaded shaft causes the installation stroke of the rivet mandrel.

[0020] The proposed riveting device can also be configured such that the first transmission system includes a reduction gear transmission, particularly a cylindrical gear transmission mechanism for reduction, which is positioned between the rivet mandrel or shaft transmission and the planetary transmission. This is advantageous for enabling the motor to have higher drive torque, especially when the motor is an electric motor.

[0021] The proposed riveting device can also be configured such that the second transmission system includes a turning shaft arranged coaxially with the axis of action, which is rotatably and fixedly connected to the rivet mandrel and configured to rotate about the axis of action. This facilitates a simple design for transmitting driving force so that the rivet mandrel can rotate about the axis of action. For example, the turning shaft is arranged coaxially with a threaded shaft. For example, the threaded shaft is constructed as a hollow shaft and the turning shaft is rotatably housed therein.

[0022] The proposed riveting device can also be configured such that the second transmission system includes at least one intermediate transmission device located between the rivet mandrel or turning shaft and the planetary transmission device. Speed ​​change or deceleration, or transmission without speed change or deceleration, can be achieved through at least one intermediate transmission device. Furthermore, driving force can be transmitted over any spatial distance between the planetary transmission device and the rivet mandrel through at least one intermediate transmission device.

[0023] The proposed riveting device can also be configured such that the transmission axis of the planetary gear is arranged parallel to the axis of action. This measure facilitates a compact construction of the riveting device, particularly a compact construction in the axial direction with respect to the axis of action.

[0024] The proposed riveting device can be constructed in different ways in its planetary transmission mechanism to achieve screwing decoupled from the first transmission system. In one possible implementation, for example, the first transmission element is specified as a planetary gear carrier, the second transmission element as a hollow gear, and the third transmission element as a central gear.

[0025] Alternatively, the first transmission component can be a hollow gear, the second transmission component can be a planetary gear carrier, and the third transmission component can be a central gear. Alternatively, the first transmission component can also be a central gear, the second transmission component can also be a hollow gear, and the third transmission component can also be a planetary gear carrier. Alternatively, the first transmission component can also be a hollow gear, the second transmission component can also be a central gear, and the third transmission component can also be a planetary gear carrier. Alternatively, the first transmission component can also be a central gear, the second transmission component can also be a planetary gear carrier, and the third transmission component can also be a hollow gear. Alternatively, the first transmission component can also be a planetary gear carrier, the second transmission component can also be a central gear, and the third transmission component can also be a hollow gear.

[0026] The term "hollow gear" in this disclosure should be understood as one embodiment of the hollow component described above in the planetary transmission. The term "center gear" in this disclosure should be understood as one embodiment of the internal component described above in the planetary transmission. In particular, the center gear is arranged so that its gear axis is coaxial with the common axis of rotation of the planetary transmission, i.e., its transmission axis. For example, the center gear is configured to rotate about the center of the transmission axis.

[0027] The term "planetary gear carrier" in this disclosure should be specifically understood as a carrier for at least one planetary gear. The term "planetary gear carrier" in this disclosure should be understood as one embodiment of the intermediate component described above in the planetary transmission. Specifically, at least one planetary gear is arranged such that its gear axis is parallel to the transmission axis of the planetary transmission. Specifically, at least one planetary gear is supported on the planetary gear carrier in a manner rotatable about its gear axis. Specifically, the planetary gear carrier is arranged coaxially with the transmission axis of the planetary transmission. Specifically, the planetary gear carrier is configured to rotate about the transmission axis of the planetary transmission.

[0028] In another embodiment, the proposed riveting device is configured as a manual riveting device. For this purpose, the riveting device may have a handle portion, for example, having a longitudinal extension transverse to the axis of action. For example, the handle portion is arranged on the device housing, particularly formed on the device housing, for example, molded onto the device housing. Through the handle portion, the riveting device can be held in the hand or manually guided. In particular, the handle portion enables the riveting device to be manually placed at the position where riveting is required.

[0029] The proposed riveting device utilizes a switchable planetary transmission. This allows for arbitrary switching between installation and tightening functions, enabling operation independently of the other transmission system depending on its active function. This decoupling of the transmission systems allows the proposed riveting device to perform the tightening function without causing translational movement of the threaded shaft. This contributes to the compact design of the proposed riveting device, as additional structural space is saved for the translational movement of the threaded shaft during the tightening process. Due to the switchable planetary transmission, a single drive motor can be used to perform both installation and tightening functions.

[0030] One approach proposes a method for operating a riveting device with both installation and tightening functions. This method can, in principle, also be performed by the riveting device described above.

[0031] The method includes the following steps: switching the undriven transmission component of the planetary gear to a driven state and switching the driven transmission component of the planetary gear to a non-driven state by means of at least one switching element, so as to disable the screwing function and enable the installation function, or conversely disable the installation function and enable the screwing function.

[0032] This enables the switching between installation and tightening functions, where the other transmission component of the planetary gear system is driven according to the activated function. In this way, the translational movement of the threaded shaft in a shaft drive, such as in a shaft drive system, can be avoided during the tightening process, as the transmission is separated between the two transmission components. In this respect, this method contributes to the compact construction of the proposed riveting device. Attached Figure Description

Detailed Implementation

[0034] Figure 1 The simplified diagram illustrates the construction of an exemplary first embodiment of the riveting device 1, also known professionally as a mounting device (Setzgerät). The exemplary riveting device 1 is suitable for placing or installing rivet screws and nuts according to a blind riveting method and is designed for use with pull rivet bolts and pull rivet nuts. Exemplarily, Figure 1 An exemplary riveting device 1 with a tightened rivet nut 100 is shown.

[0035] An exemplary riveting device 1 includes, for example, a riveting tool 2 and a drive mechanism 3 for actuating the riveting tool 2. Preferably, the riveting tool 2 is disposed to, and in particular, at least partially housed therein. Preferably, the drive mechanism 3 is housed within a device housing 5. Preferably, the tool housing 4 is supported on and / or held thereon in the device housing 5. For example, the tool housing 4 is a metal housing. For example, the device housing 5 is a plastic housing.

[0036] The exemplary riveting device 1 can be, for example, a manual riveting device. For this purpose, the exemplary riveting device 1 has, for example, a handle portion 6 with a gripping surface 6.1. For example, the handle portion 6 is connected to, and in particular formed on, or by the device housing 5. The handle portion 6 or the gripping surface 6.1 allows the exemplary riveting device 1 to be held in the hand when it is positioned for rivet mounting on a workpiece. The riveting process itself is achieved by actuating the riveting tool 2 via the drive device 3.

[0037] An exemplary riveting device 1 preferably has a rivet nozzle 10 for placement on a workpiece requiring a rivet. Preferably, the rivet nozzle 10 is fastened to a tool holder 4, for example, by a threaded connection to the tool holder. For example, the tool holder 4 has an elongated (particularly tubular) body. In this regard, the tool holder 4 is also referred to professionally as a mounting sleeve (Setzhülse). For example, the rivet nozzle 10 is fastened to one end of the tool holder 4, and the opposite end faces the device housing 5.

[0038] The exemplary riveting device 1 preferably has a rivet mandrel 20 for riveting bolts or nuts. For example, the rivet mandrel 20 is inserted into a through hole 11 of a rivet nozzle 10 and extends from the rivet nozzle 10 with its free end in an axial direction about the axis of action W. The rivet mandrel 20 is configured to move relative to the rivet nozzle 10 toward or along the axis of action W to perform an installation stroke. For example, the installation stroke is performed by displacing (e.g., pulling) the rivet mandrel 20 relative to the rivet nozzle 10 with its free end toward the device housing 5. The rivet mandrel 20 is also preferably configured to move about the axis of action W to perform tightening.

[0039] The term "tightening" is specifically understood in this disclosure to mean that the rivet nut or bolt is connected to the rivet mandrel 20 in an anti-slip manner or that the anti-slip connection is subsequently released. For this purpose, the rivet mandrel 20 utilizes, for example, the threads of the rivet nut or bolt, in such a way that the rivet mandrel 20 has, for example, a corresponding reverse thread 21, and is configured as a threaded mandrel. Figure 1 In the design of the rivet mandrel 20 used in the example, the reverse thread 21 is an external thread so as to form a connection with the internal thread of the rivet nut 100.

[0040] Regarding the term "tightening," this disclosure also uses the terms "tightening" and "loosening." The term "tightening" should therefore be understood as the connection between the rivet mandrel 20 and the rivet nut or rivet bolt, particularly an anti-slip connection. The term "loosening" should be understood as the disengagement of the rivet mandrel 20 from the rivet nut or rivet bolt.

[0041] In order to enable the rivet mandrel 20 to move both translationally and rotationally as described above, a mandrel receiving member 30 is provided, for example. The mandrel receiving member 30 is connected to the rivet mandrel 20 in an anti-slip manner and is configured to move along the working axis W. For example, the mandrel receiving member 30 is therefore housed in the tool holder 4 in a manner that allows it to be displaced in the direction of the working axis W. At the same time, the rivet mandrel 20 is rotatably supported or housed in the mandrel receiving member 30.

[0042] In the exemplary riveting device 1, two transmission systems 40 and 50 and a motor 60 (specifically, a single motor 60) are provided. The first transmission system 40 has the function of moving the rivet mandrel 20 along the working axis W. The second transmission system 50 has the function of rotating the rivet mandrel 20, specifically about the working axis W.

[0043] Motor 60 is preferably a rotary motor, and therefore has a rotatable output shaft 61. Motor 60 can be an electric motor. In this case, to power motor 60, a preferably replaceable electrical accumulator, such as a battery 7, can be provided, for example, arranged in the area of ​​the handle portion 6 away from the end of the riveting tool 2. In this regard, the exemplary riveting device 1 can be a battery-powered device.

[0044] The rivet nozzle 10 and / or rivet mandrel 20 and / or mandrel receiver 30 are, for example, assigned to the riveting tool 2, and particularly are components of the riveting tool 2. The first drive system 40 and / or the second drive system 50 and / or the motor 60 are, for example, assigned to the drive unit 3, and particularly are components of the drive unit 3. Preferably, the first drive system 40 and / or the second drive system 50 and / or the motor 60 are housed within the device housing 5.

[0045] Preferably, the first transmission system 40 includes a shaft drive 41 (particularly a ball screw drive) having a threaded shaft 41.1 and a shaft nut 41.2. For example, the threaded shaft 41.1 and the shaft nut 41.2 are arranged so that they are concentric with respect to the shaft axis of the threaded shaft 41.1. For example, the shaft axis of the threaded shaft 41.1 is located on the operating axis W. Preferably, the threaded shaft 41.1 is located on the output side while the shaft nut 41.2 is located on the drive side.

[0046] Preferably, the shaft nut 41.2 is supported in a radial direction about the shaft axis or the axis of action W in a manner rotatable, for example, relative to the device housing 5, by at least one (preferably two) radial bearings 42, 42'. Preferably, the shaft nut 41.2 is also held or supported thereon in an anti-slip manner relative to the device housing 5 and / or relative to the tool holder 4, for example, by (… Figure 1 and Figure 2 An axial bearing (not shown) provides support in the axial direction.

[0047] Preferably, the threaded shaft 41.1 faces one end toward the rivet mandrel 20. For example, this end of the threaded shaft 41.1 is connected to the mandrel receiver 30 in an anti-slip manner. Preferably, the threaded shaft 41.1 is connected via ( Figure 1 and Figure 2 (Not shown) A torque support is fixed to prevent rotation relative to the device housing 5. Preferably, the threaded shaft 41.1 is constructed as a hollow shaft having a channel 43 extending in its longitudinal extension direction.

[0048] Preferably, the second transmission system 50 includes a turning shaft 51, which is rotatably fixed to the rivet mandrel 20 and configured to rotate about the axis of action W. For this purpose, the turning shaft 51 is supported, for example, by at least one radial bearing 52 in a manner rotatable relative to the device housing 5. For example, the turning shaft 51 is arranged coaxially with the axis of action W. For example, the turning shaft 51 and the threaded shaft 41.1 are arranged concentrically about the axis of action W, wherein the turning shaft 51 is, for example, located in a channel 43 of the threaded shaft 41.1, which is configured as a hollow shaft.

[0049] In order to enable the motor 60 to be driven to be connected to the two transmission systems 40, 50, the exemplary riveting device 1 is provided, for example, with a planetary transmission device 70 preferably located in the device housing 5. For example, the planetary transmission device 70 is arranged such that its transmission axis G is parallel to the operating axis W. Figure 2 To better illustrate the transmission systems 40, 50 and planetary transmission 70, a diagram is shown according to... Figure 1 The exemplary riveting device 1 in the figure is shown, but in a magnified partial view of the area of ​​the driving device 3. For better illustration, in Figure 1 and Figure 2 The diagram also shows, in a simplified manner, elements or components of the transmission systems 40 and 50 and the planetary transmission 70 that are coaxial with the output shaft 61 and located only on one side of the output shaft 61.

[0050] In the exemplary riveting device 1, the planetary transmission 70 includes at least three transmission members, wherein a first transmission member 71 is assigned to a first transmission system 40, a second transmission member 72 is assigned to a second transmission system 50, and a third transmission member 73 is operatively connected to a motor 60. The planetary transmission 70 is specifically configured for dual-axis operation, wherein either the first transmission member 71 or the second transmission member 72 selectively acts on the corresponding transmission system 40 or 50. This is achieved, for example, by the fact that the first transmission member 71 and the second transmission member 72 are rotatable about the device housing 5 in a driven state and enter a non-driven state via at least one (e.g., two) switching elements 81, 82, in which a rotationally fixed connection about the device housing 5 exists.

[0051] For example, switching elements 81 and 82 are respectively assigned to one of the transmission members 71 and 72. Specifically, one switching element 81 is assigned to the first transmission member 71, and the other switching element 82 is assigned to the second transmission member 72. For example, switching elements 81 and 82 are configured to switch between two switching positions, wherein in one of the switching positions, the corresponding transmission member 71 or 72 is in a driven state, and in the other switching position, the corresponding transmission member 71 or 72 is in a non-driven state.

[0052] For example, in the non-driving state, the first transmission member 71 is rotatably connected to the device housing 5 or a component that is fixed to the housing relative to the device housing 5 via a corresponding switching element 81, and this rotatably connected connection is released in the driving state. In the driving state, the first transmission member 71 can rotate and drives the shaft transmission device 41 through its rotational motion, and the first transmission member 71 is connected to it in an actuating manner.

[0053] For example, in the non-driving state, the second transmission member 72 is rotatably connected to the device housing 5 or to a component that is fixed to the housing relative to the device housing 5, and this rotatably connected connection is released in the driving state. In the driving state, the second transmission member 72 can rotate and drives the screwing shaft 51 through its rotational motion, and the second transmission member 72 is connected to it in an actuating manner.

[0054] The first transmission system 40 may include a reduction gear 44, which is positioned between the shaft transmission 41 and the planetary transmission 70. For example, the reduction gear 44 is a cylindrical gear transmission mechanism. An additional reduction gear 45 (e.g., as a cylindrical gear transmission mechanism) may also be provided.

[0055] One possible arrangement is implemented in the exemplary riveting device 1. In this arrangement, for example, the first transmission member 71 is rotatably fixed to the first transmission gear 44.1 of the reduction gear 44 via an intermediate shaft 46. The second transmission gear 44.2 of the reduction gear 44 is rotatably fixed to another intermediate shaft 47, on which the first transmission gear 45.1 of another reduction gear 45 is rotatably fixed. The second transmission gear 45.2 of the other reduction gear 45 is rotatably fixed to, for example, a shaft nut 41.2, particularly formed on the shaft nut 41.2.

[0056] The second transmission system 50 may have an intermediate transmission device 53, which is located between the turning shaft 51 and the planetary transmission device 70. The intermediate transmission device 53 may be a transmission device without speed change or reduction. The intermediate transmission device 53 may also be a speed reduction transmission device or a speed change transmission device. Another intermediate transmission device 54 may also be provided.

[0057] One possible arrangement is implemented in the exemplary riveting device 1. In this arrangement, for example, the second transmission member 72 is rotatably and fixedly connected to the first transmission gear 53.1 of the intermediate transmission device 53 via an intermediate shaft 55. The second transmission gear 53.2 of the intermediate transmission device 53 is rotatably and fixedly connected to or rotatably supported on another intermediate shaft 56. For example, the second transmission gear 53.2 of the intermediate transmission device 53 simultaneously forms the first transmission gear 54.1 of another intermediate transmission device 54. The second transmission gear 54.2 of the other intermediate transmission device 54 is rotatably and fixedly connected to the turning shaft 51.

[0058] The exemplary riveting device 1 can be switched between a tightening function and an installation function via the planetary transmission 70 and switching elements 81 and 82. For example, when the tightening function is activated, the rivet mandrel 20 is rotated by the driving motion of the motor 60, preferably without translational movement of the rivet mandrel 20 and / or the threaded shaft 41.1. For example, when the installation function is activated, the rivet mandrel 20 is translated by the driving motion of the motor 60, preferably without rotational movement of the rivet mandrel 20.

[0059] The exemplary riveting device 1 may operate in the following manner: In its initial state, the exemplary riveting device 1 is activated for tightening. Therefore, the second transmission member 72 of the planetary transmission 70 is in a driven state. The corresponding switching element 82 is located in the corresponding switching device. Furthermore, the first transmission member 71 of the planetary transmission 70 is in a non-driven state. The corresponding switching element 81 is also located in the corresponding switching position.
