    摘要: A machine for driving fastening members into workpieces, comprising:
    - a reversible drive motor (3);
    - an axially displaceable tool (6); and
    - a motion conversion mechanism comprising a screw rod (9) and a nut (10) which co-operates with the screw rod, for converting a rotary motion of the output shaft of the drive motor into an axial translational motion of the tool.
    The nut is axially fixed to a holder unit (11) and is prevented from being displaced in the axial direction in connection with a mutual rotation between the screw rod and the nut, the screw rod being displaced in relation to the nut and the holder unit in the axial direction when the screw rod and the nut are subjected to a mutual rotation under the effect of the drive motor. The tool is arranged to be displaced together with the screw rod in the axial direction downwards into engagement with a fastening member when the screw rod and the nut are subjected to a mutual rotation in a first direction and in the axial direction upwards out of engagement with the fastening member when the screw rod and the nut are subjected to a mutual rotation in a second direction.

    摘要: An electric stapler (1A) includes a clamp part (2), a penetration part (3), a clinch part (4), and a motor (5). The electric stapler performs binding processing accompanying rotation of the motor by sequentially performing a clamping process, a penetrating process, and a clinching process. The electric stapler includes a first position detection unit (101) that detects that a rotational position of the motor passes a first position, a braking unit (110) that applies braking to the motor after it is detected that the motor passes the first position, a difference calculation unit (110) that calculates a difference between a position at which the motor is stopped by the braking unit and a predetermined stop target position of the motor; and a motor control unit (110) that moves a rotational position of the motor to the stop target position by rotating the motor forward or in reverse by the calculated difference.

    摘要: A nailing unit (1, 1') for nailing machines, particularly for nailing wood elements on multiple layers, comprising a clamp (40) adapted to keep in the nailing position a nail (C) above an element to be nailed, and a plunger (30) adapted to push the nail (C) in order to make it penetrate into the element to be nailed; an actuator (20, 120) which comprises a pusher element (21, 121) which moves along a vertical direction, the pusher element (21, 121) being integral with the plunger (30) and with a vertical traction rod (51) which is provided with a lower locking element (55), along which traction rod (51) the clamp (40) can slide freely to a lower stroke limit position in which it is prevented from moving further downward by the locking element (55), so that when the clamp (40) is in the lower stroke limit position an upward movement of the traction rod (51) draws upward the clamp (40); the clamp (40) comprises a through vertical tunnel (48) in which the plunger (30) can slide until it reaches the nail (C) when it is held in the nailing position by the clamp (40) and then push it.

    摘要: Nailing machine (2) for nailing wooden parts, such as palettes, wooden boxes and indented beams, where the pressing ram (3) is movable in vertical axis, the machine (2) comprises electromechanical actuators (1) for exerting mechanic pressure on the pressing ram (3). Further, the pressing ram (3) pushes the sliding bars of the hammers (4), thereby pressing the nails into wooden parts (6). The electromechanical actuator comprises a sliding rod (7), a solid part (8) with flanges for mounting to the machine (2) frame and for mounting to a spacer (9) of the drive unit (10).

    摘要: An electric tool for driving in fixing elements (10) into an object (4) by means of a magnetic field generated by supplying magnetising current to an electromagnetic device, comprises a circuit means (17) which is adapted, when activated, to supply magnetising current to said electromagnetic device. The tool comprises two actuators (18, 19) alternatively connectible to the circuit means (17) and adapted, when actuated, to activate the circuit means, one (18) of the actuators being an actuator which is activatable in a potential-free mode and which is, in an initial position, unconnected to the circuit means, and the other (19) of the actuators being connected to the circuit means in the initial position. An activating means (25) is connectible to an actuator (18') which is activatable in a potential-free mode and included in a subsequent, similar tool, said activating means being adapted to be actuated by the circuit means (17) to produce, with a time delay after the actuation of said circuit means, a potential-free signal for actuation of said actuator (18') which is activatable in a potential-free mode and included in the subsequent tool. The actuator (18) which is activatable in a potential-free mode, is activatable by an activating means connected thereto, such as the activating means (25'') of a preceding similar tool, so as to activate the circuit means (17) after being connected thereto.
