摘要:
The invention relates to an end effector for a manipulator (1), wherein the end effector interacts with a workpiece (2), wherein there is provided at least one carrier (3, 4) for a tool arrangement (5, 6), said carrier being configured in particular as a carrier plate, and wherein the tool arrangement (5, 6) serves for interacting with the workpiece (2). It is proposed that the carrier (3, 4) is formed at least in part from a deformable material, in particular from an elastically deformable material, and that the carrier (3, 4) is assigned an actuator arrangement (7, 8) by way of which the carrier (3, 4) is deformable and thus the tool arrangement (5, 6) is orientable in space.

To remove bobbins (7) from a bobbin mandrel (4) of a winding device (1), the invention suggests a sliding device, comprising a piston which, driven by a pressure medium, moves back and forth in a cylinder (8). The device is characterized in that the piston is a magnetic piston, whose polarity is opposite that of at least one magnet connected to a sliding unit (9), and in that said sliding unit (9) can slide substantially lenghtways along the cylinder (8).
摘要:
Bei einer Vorrichtung zum Fangen einer gerissenen Bedruckstoffbahn mit einer in einem für Bahnrisse gefahrdeten Bereich, vorzugsweise hinter dem letzten Druckwerk, einer Rollenrotationsdruckmaschine angeordneten, mittels einer Antriebseinrichtung (4) antreibbaren Walze (3), an die eine frei drehbare Rotoranordnung (6) andrückbar ist, die auf einem bewegbar im Maschinengestell (1) angeordneten und mittels einer im Falle eines Bahnrisses aktivierbaren Anstelleinrichtung antreibbaren Träger (5) aufgenommen ist, lassen sich dadurch ein einfacher und robuster Aufbau sowie eine wirtschaftliche Betriebsweise erreichen, daß die Betätigungseinrichtung wenigstens einen Pneumatikzylinder (12) enthält, der zum Anstellen der Rotoranordnung (6) an die Walze (3) mit hohem Druck beaufschlagbar ist und der die Rotoranordnung (6) mit reduziertem Druck an die Walze (3) andrückt.
摘要:
The tensioning device comprises at least two wheels (3, 4) with a peripheral race, rotatably installed, with substantial parallel axes, on a support (5), at a certain distance from each other. The support (5) can be orientated by being revolved around an axis substantially parallel to the axis of the wheels (3, 4), in order to move the wheels from a position in which they are not into contact with the thread (2) and are on opposite sides relatively to it, to a position of peripheral engagement with the thread (2). According to the angle of orientation of the support (5), the thread (2) engages a longer, or shorter, portion of the peripheral race of the wheels (3, 4), running according to an "S"-shaped, or "Z"-shaped trajectory. The larger or smaller extent of engagement determines a larger or smaller value of rolling friction, and therefore a higher or lower thread tension. By means of a programmed movement of the support (5), the thread tension value during processing can be varied according to a programmed schedule.

摘要:
A transfer unit (100) in an interfolding machine comprises at least a first plurality of separation members (120) carried by a support and handling assembly (130) which moves the above said separation members (120) along a work path (60) comprising a side introduction movement (61) by appropriate constraint members (140, 150, 160) and actuators which comprise electric motors (143, 152, 163) suitable to determine the displacement of the separation members (120) throughout their work path (60) and pneumatic actuators (144, 153, 164) which are of aid to the electric motors (143, 152, 163) exclusively during the side introduction movement (61) which must be performed with very high accelerations and speeds.
摘要:
Thread clamp, in particular for a weaving machine, which at least consists of an actual clamp (2) with at least two clamping parts (3-4) between which a thread (5) can be clamped, as well as of actuation means (6) for moving said clamping parts (3-4) in mutual respect between at least two positions, a closed position, whereby the clamping parts (3-4) are pushed towards each other, and an open position whereby the clamping parts (3-4) are situated at a distance from each other, respectively, characterized in that said actuation means (6) comprise at least a pneumatically actuatable part (7) for bringing the clamp (2) into at least one of said two positions, which part can be actuated by means of a negative pressure, more particularly vacuum, fed thereto.
摘要:
Ce dispositif de freinage comprend au moins un organe de freinage souple (1) s'étendant transversalement à la trajectoire des feuilles et susceptible d'être déplacé entre au moins deux positions limites, l'une dans laquelle sa trajectoire rencontre celle desdites feuilles, l'autre dans laquelle ledit organe de freinage est écarté de la trajectoire desdites feuilles. Le dispositif comprend également des moyens d'entraînement pour déplacer ledit organe de freinage entre lesdites positions limites, lesdits moyens d'entraînement dudit organe de freinage (1) comprenant un actuateur pneumatique (3) qui agit sur une came linéaire (4) pivotant autour d'un axe transversal (5), et un galet (7) roulant le long de la surface (6) de la came linéaire (4) ; le galet (7) et l'organe de freinage (1) étant portés par un support (8) pivotant autour d'un axe transversal (2).
