摘要:
In a jacquard system of a weaving machine in which hooks are actuated by harness cords controlled by knives carried by belts supported on drums drivingly connected to drum disc shafts, independent motors having output shafts are provided for driving the drum disc shafts. The motors are controlled to reciprocate the movement of the belts by first sensors monitoring the rotational movement of the motor output shafts and second sensors monitoring the rotational movement of a primary drive shaft of the weaving machine.
摘要:
A speed reducer of the cycloidal type for robots and other industrial manipulators which includes actuation fingers introduced in openings of toothed cams controlled by rotating eccentrics. Each actuation finger is formed by a roller bearing having an inner ring mounted about a pin with clearance to thereby allow self-centering of an outer ring of each roller bearing in its respective opening.

This invention is directed to improved mobile hooks for the shed forming device of weaving looms wherein the mobile hooks are disposed at each of the ends of a funicular element. Each hook includes a web bordered by a vertical heel disposed in a slideway formed by grooves made in two opposing separating partitions with the web including a toe adapted to be hooked by the curved ends of a conventional blade element which is utilized to maintain the hooks in their uppermost elevated position. The hooks further include portions which are adapted to be gripped by conventional knives as the knives are moved vertically in reciprocating motion and also a push element adapted to displace the hook retaining blade against the core of an electromagnet which is used to selectively urge the retaining hook into engagement with the mobile hook when the electromagnet is activated.
摘要:
A lifting beam for the shed forming device in a weaving loom which includes a fork joint made in the form of two cheeks or pairs of opposing flanges having aligned openings formed therein through which the stub shaft of two pulleys are rotatably mounted. The pulleys are made of an appropriate plastic material which is overmolded over the metal pins or shafts with opposing grooves provided in the interfaces of the cheeks to facilitate positioning of the pins in the openings.

The present invention relates to improvements in rotating dobbies. The control of the coupling pawl for connection to the driving shaft is effected by one of two right-angled pivoting levers actuated in the same zone by push elements of the reading device of the dobby. When a lever engages in a notch in a plate fixed to the eccentric, the nose of the engaged one of the pivoting levers pushes a catch on the pawl which pivots the pawl causing the withdrawal of its finger to release connection with drive from the shaft.
摘要:
The articulated structure for a multi-axis robot comprises a stationary base; an arm hinged to the base about a first axis; a forearm hinged to the arm about a second axis parallel to the first axis, the forearm forming a deformable parallelogram structure and comprising two connecting rods that are hinged to two plates about respective axes that are perpendicular to the first and second axes. This structure also comprises a first electric actuator controlling pivoting of the arm about the first axis; a second electric actuator controlling pivoting of the forearm about the second axis; and a third electric actuator controlling pivoting of one of the connecting rods relative to the plates about the axes that are perpendicular to the first and second axes. The third actuator is mounted on the base or on the arm.
摘要:
This robot structure comprises a base structure (2), at least a first arm (40) that can move with respect to this base structure, both in terms of translation and in terms of rotation, movement means (12, 22, 32) for moving this first arm with respect to the base structure, an accepting member (70) for accepting a tool (72), and a power supply assembly (80).The movement means comprise a hollow movement member (32) which is able to move in terms of translation with respect to one of either the base structure or the first arm, and is incapable of translational movement independently of the other of either the base structure or the first arm, this hollow movement member being able to move in terms of rotation with respect to one of either the base structure or the first arm, while at the same time being incapable of rotational movement independently of the other of either the base structure or the first arm, whereas the power supply assembly (80) extends, from the base structure towards the first arm, through the hollow movement member (32).
