Definitions
- the invention relates to the technical field of installations or machines for processing continuous elongated materials set in motion by the effect of scrolling along their own trajectory.
- continuous elongated materials mention may be made of textile threads, ribbons, bands, etc.
- the invention relates to the control of the means for setting in motion the material capable of causing it to advance along its own trajectory.
- these means there may be mentioned by way of non-limiting indication of cylinders, pulleys, endless belts, rollers, buckets or other bodies driving the elongated material by friction, pinching, meshing effect, ...
- the material is previously arranged along its path, while the movement setting members are stopped. This operation is called “threading” in the case of textile yarn processing machines.
- the moving members are then started and gradually accelerated so that they can reach the required nominal speed depending on the work to be performed. In general, accelerations are programmed according to synchronized ramps which maintain constant gear ratios.
- This solution requires the use of synchronized start and stop means. This solution is not applicable for certain members such as those used in a heat treatment, and liable to burn the material which is static, since when the start-up is started, the material does not pass.
- another method consists in starting the organs for setting in motion the material beforehand and bringing them to nominal speed then in engaging the said material. It is only when the nominal speed is reached that the material is introduced at the entry of the movement setting members, so that the material is caught up and brought instantly to the nominal speed.
- the material is presented by a device which gives it an initial speed close to the nominal speed of the treatment process.
- this device can consist of arms associated with suction nozzles such as those commonly used in the field of textile machines.
- This solution is however difficult to apply in the case of high-speed processes for fragile materials which do not withstand sudden accelerations, generally when the material is caught. When the operation is carried out manually, it requires great skill on the part of the operator. There are also safety concerns since the operations are carried out on moving parts.
- the object of the invention is to remedy these drawbacks in a simple, safe, efficient and rational manner.
- the problem which the invention proposes to solve is to control organs for setting in motion filiform products such as textile threads, ribbons, strips during the start-up phase and along their own trajectory.
- a method has been devised for controlling the linear drive members of a filiform product, in particular a textile thread during the start-up phase, each of said members being subjected to an electric motor, the motor being associated with the minus one control unit capable of receiving speed and / or speed report instructions and start / stop orders.
- the control unit of the member is subjected to a means for measuring the speed of said member; - when a start command is received, the engine does not start if the measured speed is zero; - Information representative of the measured speed of the drive member is monitored; - a control sequence is triggered which can cause the motor to rotate, according to a pre-programmed speed setting profile when a rotation caused by an external intervention is detected.
- the starting mode can only be engaged when the engine is initially stopped. Switching this operating mode does not trigger an engine control sequence such as to cause it to immediately rotate according to an acceleration profile. On the contrary, according to the invention, switching over to this operating mode can possibly, if the technology of the motor allows, cause the creation of a limited holding hold torque. This torque can be configurable and controlled by limiting the voltage or current, for example.
- the driving sequence of the motor is initiated so as to cause it to rotate according to a programmed speed setting profile.
- the process includes:
- the external intervention consists of the drive of the wire and / or of the drive or movement member for said wire, said drive being carried out manually by an operator or by auxiliary means.
- the speed setting profile is a linear ramp or any shape.
- the speed setting profile may include a plateau at constant intermediate speed, different from the nominal speed setpoint:
- the intermediate speed of the chainring can be preprogrammed.
- the intermediate speed of the platform can be the speed of rotation created by external intervention and measured by the control system for a few moments after its detection.
- this control sequence determines a torque limitation (motor or brake), controlled for example by a voltage or current limitation:
- This torque limitation can be fixed. This limitation of the torque can depend on the speed of rotation.
- This torque limitation can be maintained for a preprogrammed time. This torque limitation can be maintained until the speed reaches the speed of the intermediate speed plate. This torque limitation can be maintained until the end of the intermediate speed chainring. This torque limitation can be maintained until the speed reaches the nominal speed setpoint.
- the device comprises members for moving the wire subject to at least one control unit capable of receiving at least one speed signal, the motor being of variable reluctance or of magnets permanent and whose supply sequence is a switching sequence of the windings supply synchronized by signals representative of the position of the rotor relative to the stator, said signals can be used to measure and detect the speed of rotation.

- the processor (6) can receive start, stop, ... orders, via the network or via other inputs / outputs.
- the control unit (3) of the electric motors (2) receives information representative of the speed of the means (1) for setting in motion the filiform element.
- At least one of the movement setting members is subjected to a particular starting mode characterized by the following essential provisions: this starting mode is engaged when the engine is initially stopped ; switching to the operating mode does not trigger an engine control sequence capable of causing it to immediately rotate according to an acceleration profile and may possibly, if the technology of the engine allows, cause the creation of a limited torque holding stationary; the control unit monitors the information representative of the speed (phase (A)) of the setting members in motion, so that the holding while stopped (and possibly the limited holding holding torque) is maintained as long as the rotation resulting from an external intervention is not detected.
