    • An apparatus monitors an a.c. motor (12), a door (14) operated by the motor, a frequency converter (16) for supplying electric power to the motor (12), and a control and signal-processing means (32) which causes the frequency converter (16) to control the door in accordance with a desired movement. The movement of the door is continously detected. The control and signal-processing means (32) compares the desired movement of the door with the detected movement, in order to emit an alarm signal (L) when the difference is too considerable. A switch means (28) thus blocks the power supply to the motor (12). A sensing means (31) senses whether the power supply to the motor (12) is blocked. The alarm signal (L) is repeatedly emitted in order to establish a possible malfunction of the switch means (28).

    • A welding device applies weld material between two work pieces (P1, P2) so as to connect the work pieces (P1, P2) mechanically with one another. The welding device has a welding head (110) and a probe head (120). The welding head (110) performs a welding action in respect of the work pieces (P1, P2) during transport of the welding device along an operating direction (OD) in a welding plane (WP); and the probe head (120), which is arranged upstream of the welding head (110) relative to the operating direction (OD), measures a set of geometric properties of a gap (G) between the work pieces (P1, P2). Thus, the welding head (110) can be properly positioned to attain a desired application of the weld material in the gap (G). Moreover, first adjustment means allow a position of the probe head (120) relative to a position of the welding head (110) to be varied angularly by rotating at least one of the probe head (120) and the welding head (110) around a first axis (A1 ) oriented essentially perpendicular to the welding plane (WP). Thereby, welding in narrow and curved gaps (G) is facilitated.
    • 焊接装置在两个工件(P1,P2)之间施加焊接材料,以将工件(P1,P2)彼此机械地连接。 焊接装置具有焊接头(110)和探头(120)。 在焊接装置沿着焊接面(WP)的工作方向(OD)传送时,焊接头(110)相对于工件(P1,P2)进行焊接动作。 并且相对于操作方向(OD)布置在焊接头(110)的上游的探头(120)测量工件(P1,P2)之间的间隙(G)的一组几何特性。 因此,可以适当地定位焊接头(110)以获得在间隙(G)中期望的焊接材料的应用。 此外,第一调整装置允许探头(120)相对于焊接头(110)的位置的位置通过使探头(120)和焊接头(110)中的至少一个旋转至周围而发生角度变化 基本上垂直于焊接平面(WP)定向的第一轴线(A1)。 由此,便于在窄且弯曲的间隙(G)中进行焊接。

    • A weld device (100) applies weld material between two work pieces (P1, P2) such that the work pieces (P1, P2) are connected mechanically with one another. The weld device (100) includes a welding head (110) and a central element (120). The welding head (110) performs a welding action during transport thereof along an operating direction (OD) between the work pieces (P1, P2).Two primary sensor members (S R , S L ) are arranged on the central element (120) upstream of the welding head (110) relative to the operating direction (OD). The sensor members (S R , S L ) register geometric properties of a spacing (G) between the work pieces (P1, P2) in which spacing (G) the weld material is to be applied. Each sensor member (S R ; S L ) is configured to maintain contact with a respective wall (W1, W2) of the two work pieces (P1, P2) adjoining the spacing (G)while allowing variation of lateral distances (d R , d L ) between the central element (120) and the adjoining wall. This is accomplished by the sensor members(S R , S L ) being pivotally attached to the central element (120) via at least one pivoting axis (P) oriented essentially perpendicular to the operating direction (OD).
    • 焊接装置(100)在两个工件(P1,P2)之间施加焊接材料,使得工件(P1,P2)彼此机械连接。 焊接装置(100)包括焊接头(110)和中心元件(120)。 焊接头(110)在沿着工件(P1,P2)之间的操作方向(OD)的运输期间执行焊接动作。两个主传感器构件(SR,SL)布置在中心元件(120)的上游 所述焊接头(110)相对于所述操作方向(OD)。 传感器构件(S R,S L)对应于要施加焊缝材料的间隔(G)的工件(P1,P2)之间的间隔(G)的几何性质。 每个传感器构件(SR; SL)构造成与邻接间隔(G)的两个工件(P1,P2)的相应壁(W1,W2)保持接触,同时允许横向距离(d R,d L )在中心元件(120)和相邻壁之间。 这通过传感器构件(S R,S L)经由基本上垂直于操作方向(OD)定向的至少一个枢转轴线(P)枢转地附接到中心元件(120)来实现。
