Problems solved by technology

[0006] However, such devices have no position control, their torque is limited and not sufficient for the specific application, and finally, with these devices it is not possible to preselect the swivel amplitude, which is determined in a defined manner by the geometry of the structure
[0007] Finally, these devices have difficulty controlling the position at the end of the swing
[0008] Another controlled positioning device known at present is of the parallelogram type; the mechanical structure of this device is complex and, due to the lever means and the mass of the movable equipment, the above-mentioned device has a larger inertia, less electrical efficiency and higher cost
[0009] A third type of controlled positioning device currently known employs conventional servo motors with stepper motors or "brushless" motors for actuating small heddle-carrier looms ; however, these devices have considerable disadvantages due to their large size and high combined overall cost

Embodiment Construction

[0020] The device that is the object of the present invention consists essentially of an angular position controlled motor in which a direct current is delivered to a "brushless" rotor connected to a series of elements including cables and heddle carrier looms ), the motor can make the above-mentioned small heddle projectile loom reciprocating, so that desired organization is obtained between the weft and warp.

[0021] Referring to the above drawings, the angle servo motor according to the present invention basically consists of a rotor 1 rotating on a shaft 1 ″ which forms a part of a fixed plate 2 .

[0022] The rotor 1 in turn comprises a winding 1' through which a current fed by a conductor 3 flows, and is equipped with a plurality of control sensors 4.

[0023] In addition, on the stator 7 are fixed magnets 2', 2", said magnets being suitably shaped for this purpose.

[0024] The moving element constituting the device object of the invention consists of the cable 5 whic...

Abstract

An angular servo-motor for the controlled positioning of elements connected to weft or warp yarns, in a weaving machine, essentially comprising a position control angular motor, with direct current sent to a 'brushless' rotor (1), the latter connected to a sequence of elements consisting of cables (5) and small heddle-carrier looms (10, 11); the servo-motor in question is capable of conferring an alternating motion to the aforesaid small heddle-carrier looms (10, 11), such to obtain the desired weaves between the weft and warp yarns.

Description

technical field [0001] The present invention relates to an angular servomotor for the controlled positioning of elements attached to weft or warp threads in a weaving machine. [0002] More specifically, the invention relates to angular position control servomotors suitable for driving devices dedicated to the control of one or more weft or warp threads, said servomotors being determined to be suitable for the purpose for which they are dedicated The positioning of elements where one or more yarns interact. Background technique [0003] In the case of controlling the position of the yarns, in particular the binding yarns of the lateral edges of the fabric, the mechanism object of the invention is able to drive the element on which the heddles (said heddles controlling the binding yarns) are mounted, In order to obtain on both sides of the fabric the weft yarns necessary for the process of forming and joining the two edges of the fabric. [0004] This operation is associate...
