Definitions
- the present invention relates to a process for activating, upon interruption of the thread, a flexible and modulating winding cycle which can be a preparation, recontinuation or finishing cycle; the invention also relates to suitable equipment for this process. More specifically, the present invention relates to a process for activating a winding cycle which detects the operating procedure of each subsequent phase of the whole thread-winding cycle, allowing continuation to the subsequent phase in the case of an acceptable result, or blocking the cycle when the result is not sufficient to proceed to the winding phases and in the latter case establishing a repetitive action and, if necessary, repositioning in retroaction to a previous phase.
- DE-A-3 644 433 describes a process for activating a winding cycle which detects the operating procedure of each subsequent phase of the whole thread-winding cycle, allowing continuation to the subsequent phase in the case of an acceptable result, or blocking the cycle when the result is not sufficient to proceed to the winding phases.
- This bobbin is subsequently fed to an automatic winding station for a subsequent operation wherein the thread of the cop is wound in a preset quantity onto a bobbin having a pre-established shape, whereas any defect in the thread is removed therefrom.
- a thread is drawn from a cop, which is fed by various feeding devices to a preset position of each winding unit, and this thread is passed into tension devices, into an electronic slub catcher, or any other electronic yarn cleaning device, after which it is wound onto a bobbin which is made to rotate by means of a known grooved cylinder.
- the spinning cops Owing to the mechanical limitations of a continuous ring spinning machine, the spinning cops have a relatively small quantity of wound thread, up to several hundreds of grams at the most.
- the present invention therefore not only has the object of considerably increasing the production of bobbins of wound thread, but also of ensuring the correct operational functioning of automatic winding.
- the present invention relates to a process for carrying out a winding cycle by the continuous automatic indication of data relating to the winding process in its operating sequences, thus activating the preset winding phases each time rewinding is necessary at the single collecting station of an automatic winder, this process comprising the following phases:
- the process comprises the compulsory control of the operating parameter values which regulate the functioning of the operating phase itself to vary them and adapt them to the correct functioning of the repeated operating phase.
- the invention also relates to the equipment for embodying the above process, this equipment comprising:
- the electronic slub catcher 12 can be of the conventional type or may contain an electric sensor-transducer 18, or capacitive such as a thread-presence feeler or exploration device. It produces a feeler signal which is amplified in the preamplifier 22, according to a direct current, or alternating current, and is conveyed to the part of the governing unit 20 through connecting cable 41; 13 and 17 are optoelectric sensors for controlling the thread-presence and thread-tension and they generate electric signals which are passed to the governing unit through connecting cables 44 and 43; 24 is a disk probe which generates impulses in correspondence with the rotation of the control cylinder 23.
- This impulse generator 24 indicates the number of revs of the grooved cylinder 23 and continuously transmits, through connecting cable 40, these rotation impulses to the governing unit 20.
- this latter unit 20 uses these rotation impulses for the regulation of the velocity of the cylinder 23 in its various operating phases, for the cross-tangling device, for controlling the winding onto cylinder 23 itself; 28 is a disk probe which generates impulses in correspondence with the rotation of the bobbin of wound thread 21.
- the above generated impulses are sent, through the connecting cable 38, to the governing unit 20, which processes them for calculating the diameter of the bobbin, for measuring the length of wound thread and for controlling the free rotation in the recontinuation cycle and in the final free run before changing the bobbin;
- 15 is the guide shoe device, or thread tension washers with a breaking action elastically regulated by means of an electromagnetic activator 16, which receives control and piloting impulses from the governing unit 20 to vary the supporting pressure of the guide shoes on the thread being wound;
- 19 is a proximity sensor, known in the art, which continuously indicates the traverse motion of the thread being wound onto bobbin 21, and this traverse movement generates impulses which, through cable 42, are sent to the governing unit 20, which is informed of the regular winding in process;
- 14 is the thread balloon, which is rapidly unwound from cop 11;
- 20 is the governing unit, based on a miniprocessor suitable for memorizing the operator's instructions, introduced by means of the control board 30 and connecting cable 32, and it
- the governing unit 20 which controls the whole operating equipment of the present invention.
- the governing unit 20 according to its intern program, which controls the recontinuation cycle, sends, through cable 37, electric impulses which activate the inverter with varying frequencies 2, which feeds and pilots the driving element 5, in its angular rotations, the latter being indicated by the probe disk 1 which generates a series of electric impulses, which are sent to the governing unit 20, through connecting cable 33, to activate a control of the operating phases of the recontinuation closed-ring cycle; 31 is the cable which transmits the operator's instructions introduced along the winding front of an automatic winder.
- Figure 1 shows an example scheme of a winding station.
- the thread extracted from a spinning cop (hereafter referred to as cop 11) situated in a fixed position passes through a balloon-breakage element 14, thread-presence control sensors 13 and 17, a thread-tension guide-shoe device 15 with a regulated breaking action and a device for indicating thread defects of the photoelectric type, or with electric capacitance as a slub catcher 12 and is wound, as it is moved sideways, onto a bobbin 21, which is activated by a control cylinder 23.
- a signal is sent with a thread-cutting instruction whereby the cutting device (not shown) is activated and the compulsory cutting of the thread is effected.
- the thread-presence signals emitted by sensors 18, 17 and 13 stop and a signal is immediately sent out from the governing unit 20, which activates the operating sequences of the recontinuation cycle and, then the thread-joining instructions.
- the governing unit 20 emits a series of signals which activate in succession and/or temporary overlapping, instructions for starting the operating sequences of the winding recontinuation cycle.
- the thread movement stops and sensors 13, 18 and 19 communicate the disappearance of the dynamic thread-run signal to the governing unit 20, and this unit 20 disactivates the motor 7 of the control cylinder 23 and at the same time activates both the electronic breaking of the motor 7 itself and the bracket lift for separating the bobbin 21 and cylinder 23.
- the thread-guide cylinder 23 and bobbin 21 stop and this is indicated and communicated by the rotational probes 28 and 24.
- the upper suction mouth 27 contemporaneously rotates by means of the driving element 3, which is activated and piloted by the electronic device 4, which receives impulses programmed by the governing unit 20 (see figure 4 and position "b" of figure 2).
- the suction slot of the mouth 27 is positioned in correspondence with the contact generator between bobbin 21 and cylinder 23, which in the meantime are attached to each other in their state of rotational stop (see figure 5 and position "c" of figure 2).
- the governing unit 20 activates the motor 7, which inverts its rotation direction and makes the cylinder 23 and bobbin 21 slowly rotate backwards for at least one or more suction attempts depending on the instructions received and preset by the operator in unit 20, through board 30.
- the backward rotation automatically adapts itself to the diameter of the bobbin 21, and is lesser for large diameters.
- there are two consecutive attempts at withdrawing the thread-end wound onto the bobbin 21 see figures 6, 7 and 8 and position: "d", "e” and "f” in figure 2), and one or more attempts at thread suction can be made.
- the governing unit 20 activates the descent of the suction mouth 27, which inserts the caught thread-end into the slub catcher 12.
- the slub catcher verifies with sensor 18 the presence of the thread itself and sends an amplified thread-presence signal to unit 20, which immediately activates the driving elements 3 and 6 to send the two thread-ends, lower and upper, into the joining device 25, to effect the joining of the thread (see figure 10 and position "h" of figure 2).
- the governing unit 20 activates in succession, by means of the electronic device 8, the driving element 9 responsible for activating the knotter 25.
- the governing unit 20 blocks the activation of the driving elements 9 of the knotter 25 and repositions the recontinuation cycle, with retroaction, into the suction phase of the thread-end in position "d" of figure 2 (see also figure 6).
- the governing unit 20 when retroactivating the subsequent operating phases changes the functional and operative parameters of the phase which has not been effected or effected with a non-acceptable result, according to a preset diagnostic program, to allow the non-effected phase to be regularly carried out with an acceptable result to successfully complete the winding recontinuation cycle in the shortest time possible.
- the process and equipment of the present invention consequently permit operation with such a control as to avoid blocking the winding station, thus eliminating alarm signals and interventions on the part of the operator.
- the motor 7 starts and by means of the thread-guide cylinder 23 the bobbin progressively accelerates its rotation until it reaches, without slipping, the standard rotation velocity.
