Illustrate the method (Figure 10) for running cutter device 10 below.

Preferably, only when blocking device in the second position when can manipulate cutter device.Preferably, this second The charging process of cutter device is not provided with position.Cutter device 10 is constantly in a kind of operational mode.Once switch 72 Closure, control unit 52 activate drive motor 20.But substantially also, it is contemplated that cutter device 10 especially has additional fortune Row switch, can activate and disable cutter device 10 by means of the run switch.Alternatively, also, it is contemplated that cutter device 10 can for example be activated automatically by the closing of the restriction of cutter device 10 and/or opening sequence.Such as it is contemplated that according to when Between disabled.

If operator wants to implement cutting process during operation, such as cuts off branch, then the operator will must treat The cut substrate 11 of cutting is positioned between the cutting element 12,14 of cutter device 10.Then, especially such as in the garden shear of routine Like that, can be by 16,18 extruding relative to each other of grip element come closing of cutting element 12,14.Grip element 16,18 is in step Manually it is forced together by operator in rapid 1180.Without departing from the spring force of force snesor 40, switch 72 does not send signal. In step 1200, control unit 52 monitors force snesor 40 or switchs 72 signal.Therefore, control unit 52 is monitored for cutting Cut the power needed for process.Control unit 52 checks that the switch 72 of force snesor 40 is opening or closure.

If the power F being used for needed for cutting process of operator_userLess than by force snesor 40 it is limiting, in order to close out The power needed for 72 is closed, then cutter device 10 is used in manual mode.If switch 72 is opened, in branch 1220 then Repeat step 1200.In manual mode, operator manually makes grip element 16,18 pivot relative to each other.In manual mode In, rope 32 by means of reset unit 31 in other words spring element 36 on capstan winch 32.Because power is herein by slave end It is applied on clutch unit 22, clutch unit 22 is under open mode.Therefore, capstan winch 32 can be in no transmission device Reversed in the case of the resistance of unit 38 and driver element 20.In this state, rope 34 is remained by spring element 36 and opened Tightly.If operator is because such as cutting process terminates and reduced the power being applied in grip element 16,18, grip element 16th, 18 it is separated from each other by means of opening spring 50 and opens cutter device 10.Here, rope 34 resists the bullet of spring element 36 Spring force is from the uncoiling of capstan winch 32.

If the energy-storage units 54 of cutter device 10 are empty, cutter device 10 can use in manual mode, its In, driver element 20 also keeps disabling when beyond the power limited by force snesor 40.Without swashing for driver element 20 Living, thus, clutch unit 22 also stays open.

If the power F for the operator needed for cutting process_userMore than by force snesor 40 it is limiting, in order to close out The power needed for 72 is closed, then cutter device 10 is used in auxiliary mode.Conversion from manual mode to auxiliary mode substantially exists Carried out in cutting process.In manual mode, operator manually makes grip element 16,18 pivot relative to each other.If cutting Hard cut substrate 11, then operator grip element 16,18 must be made to extrude relative to each other with high power.If apply so high Power so that switch 72 is overcoming spring force F_gsWhen close, then this controlled unit 52 detects.Therefore, control unit 52 activates Driver element 20.If determining the closure of switch 72 in branch 1220, activated and driven by control unit 52 in step 1240 Moving cell 20.Therefore, when beyond the operating physical force of restriction, driver element 20 is switched to the close mechanism of cutter device 10.Therefore, The inner rotation element 46 that driver element 20 passes through the driving clutch unit 22 of actuator unit 38.Driver element 20 is along driving Direction 41 is driven.Clutch unit 22 closes and drives capstan winch 32.Rope 34 is on capstan winch 32.Except operating physical force F_userOutside additionally by driving force F_asGrip element 16,18 is forced together or is drawn together.Under this running status, In partially manual motion, driver element 20 loads cutting element 12,14 with additional force.Herein, driving force F_asPass through strand Disk 32 is acted on rope 34.

Herein, driving force F_asActed on by rope 34 on lever 80.Once in addition, operating physical force F_userPassed more than by power Power that sensor 40 limits, needed for for closure switch 72, then also pass through driving force F_anAuxiliary hand-operating moves., whereas if behaviour Make power F_userSo weakening causes switch 72 to open, then driver element 20 stops in step 1260.When two grip elements 16, When 18 closures are mutually touched by being spaced apart element 630 in other words or object 17 is arranged between grip element 16,18, thus Equally not less than by force snesor 40 it is limiting, for closure switch 72 needed for power, then can also realize that driver element 20 exists Stopping in step 1260.In this state, operating physical force F_userIt can not be further continued for being applied on force snesor 40, because driving Power F_asActed on by rope 34 on lever 80 and the lever motion is switched into its initial position in the initial position 72 open.Then, in step 1280, driver element 20 is briefly driven along reverse drive direction 410, to open clutch Device unit 22.Braking member 28 brakes retainer 26, and clamping body 24 no longer makes the external rotating element and inner rotation element 46th, 48 clamp.Therefore, can briefly, be, for example, less than 100 milliseconds, especially 40 milliseconds to cancel driver element 20 to drive in other words Direction reversion of the drive division of moving cell 20 along reverse drive direction 410.Then, driver element is disabled in step 1300 20.After the deactivation of driver element 20, methods described is from the beginning.

Substantially, in the case where rotational motion stops, clutch unit 22 can also make driver element 20 voluntarily decoupled. Here, when the rotational motion of driver element 20 stops, cutter device 10 in principle can also be by opening at least portion of spring 50 Ground is divided to open, and here, capstan winch 32 is partly reversed by rope 34 against the driving direction 42 of driver element 20.Here, The inner rotation element 46 of clutch unit 22 can equally occur relative to the torsion of external rotating element 48 and therefore beat Declutch unit 22.But substantially it is also contemplated that other are used for the method for opening clutch unit 22.
