Abstract:
Method and device (10) to manage a coiler apparatus (11) associated with a distributor (15), in which there is at least an exit of the feeder (21) of hot or cold semi-worked metal products, and with a reel (16), both being respectively moved with suitable controlled movement and rotation means, able to manage the coiling obtaining coils with desired characteristics.
Abstract:
A device for controlling the lag angle of optical fiber as it is wound on aobbin prior to the fiber wound bobbin being placed in a missile and payed out during flight on the missile. The device includes a laser light source which is projected into the groove between the turns of fiber being wound on the bobbin. A hemispherical detector receives the reflected laser light as it tracks the light between the grooves and any difference in the light intensity that is received by the detector is amplified and is used to speed up or slow down a reversible, variable speed motor which controls the winding of the fiber on the bobbin.
Abstract:
A sliding base is guided for vertical movement on an upright of the traverse mechanism. It bears a camera having its lens directed along a horizontal axis toward a vertical bank of lights. A drum supported by uprights and driven rotatingly by a motor can move back and forth on rails, while the traversing carriage bearing vertical rolls guiding a cable can likewise move parallel to the axis of the drum in order to check and, if neccessary, modify the approach angle formed by the incoming cable about to be laid on the winding. The silhouette of the zone of the winding where the turns are laid down is formed on a receiving surface within the camera, this surface taking the form of a photodiode grid, the periodic scanning of which yields signals sensing the conditions under which the cable is being wound.
Abstract:
A control device for obtaining a uniform or even winding is provided for a winding machine for winding strand-shaped winding material, and includes an electrical scanning device which detects the transition from a winding layer into a next higher winding layer by detecting the step that is formed during such transition. The scanning device does not make physical contact with the winding layer but relies on detection information furnished by opto-electrical or acousto-electrical sensing elements. This information is used to control the reversing of movement of a feed drive which effects the relative reciprocating traversing movement between the spool and a strand guide.
Abstract:
An apparatus and method for winding cables onto a rotatably driven cable drum without gaps, an oncoming cable being wound in a new coil directly next to the preceding coil at the running-on point, and the running-on angle of the cable being corrected if a monitoring device finds a gap between the last coils. A marking that changes over time is applied to the cable by a marking device before it is wound, and in the marking is detected at least in the new coil and the preceding coil, it being possible for the new coil to be differentiated from the preceding coil.
Abstract:
Strand-shaped winding material is continuously supplied to a coil, whereby the position of the winding material is observed with at least one video camera, whereby the data about the wrapping obtained in this way are conducted to a computer unit that initiates a corresponding readjustment. With reference to the coil axis and as seen in radial direction, the position of the apexes of the turns is identified for at least respectively two turns of the new winding ply, and, given a deviation of these apexes from a rated value, a readjustment is implemented in the delivery of the winding material.
Abstract:
In precision winding of fibers onto a bobbin mounted on a mandrel, a suity positioned circuit of lag angle detector, differentiator, threshold and status latch detect the occurrence of a crossover event while a suitably positioned circuit of angle counter, turn counter and data latch record the absolute mandrel angle and the number of complete revolutions of the mandrel at each occurrence of the crossover event. A computer coupled to the status latch and data latch graphically depicts the absolute mandrel angle versus the number of revolutions at the time of each crossover occurrence. This graphic depiction simulates the crossover pattern, thus making it possible to observe the pattern without stopping the winding process to inspect the pattern visually.
Abstract:
System for controlling the loading or unloading a cable [2] or the like onto a drum [3], wherein the drum [3] has a known first rotation axis loading or unloading the cable, the system also comprises an imaging means [1] aimed at the cable [2] from a position at a distance from the drum rotation axis, the imaging means [1] being adapted to measure the direction of the cable [2] relative to the rotational axis of the drum. The imaging means can be constituted by a video camera.
