Definitions
- the invention regards a blowing controlling device for rectilinear combs of a combing machine.
- a carding process is executed by a carding machine, following which the fibre is in the form of a sliver.
- FIG. 1 illustrates a diagram of a control device in accordance with the present invention, according to a first embodiment
- figure 1a illustrates a side view of a control disc of the control device of figure 1 , according to a variant of the embodiment
- FIG. 1 illustrates a diagram of the control device, according to a further embodiment
- figure 2a illustrates a side view of a comb shaft of the combing machine on which is applied the control device of figure 2;
- FIG. 3 illustrates an operational diagram of the control device, according to an embodiment
- FIG. 4 represents a diagram of the control device, in accordance with a further embodiment
- FIG. 5 represents a diagram of the control device, in accordance with yet a further embodiment.
- 1 shows a pinching device of a combing machine, to which is fed a fibre lap.
- the pinching device 1 comprises a lower jaw 2 and an upper jaw 4, incident to the lower jaw 2 to pinch the lap between the tips.'
- the combing machine comprises a rectilinear comb 9, usually fastened to the pincer support 6, alongside the upper jaw 4, opposite the lower jaw
- the rectilinear comb 9 has also at least one blowing nozzle in the comb body 9' to blow compressed air between the teeth 9".
- the combing machine comprises a circular comb 14 mounted in rotation on a combs shaft 16.
- the needles 22 penetrate the head of the lap strand, combing it.
- the movement of the pinching device 1 is mechanically correlated to the rotation of the circular comb.
- the combing machine 1 comprises a brushing wheel, motorised for example, next to the disc 18 of the circular comb, opposite the disc 18 in relation to the pinching device.
- the brushing wheel is suitable to brush needles 22 of the circular comb 18 to separate the tangled fibres and the impurities accumulate between them.
- the blowing device comprises a solenoid valve 40 and a source of compressed air 42 connected to the solenoid valve.
- the rectilinear comb 9 is operatively connected to the solenoid valve 40 to receive compressed air from it destined to exit from the needles of the comb body 9'.
- the control device comprises a control shaft or a control disc 50 connected to the comb shaft 16 so as to create a desired drive ratio with it.
- control device also comprises at least one sensor 60 and a related signalling element 62, connected to the control disc 50.
- control device comprises a rotating plate 70 that can be angularly positioned in an adjustable manner in relation to the control disc 50.
- the sensor 60 is connected to the rotating plate 70.
- the rotating plate 70 can be accessed by an operator and manually adjusted.
- the angular position adjustment of the sensor 60 allows to anticipate or delay the sending of the position signal Sp in relation to a fixed angular reference or in relation to a particular phase of the combing cycle.
- the control device also comprises an enabling unit 80 suitable to send an enabling signal Sa if any enabling conditions occur.
- a first enabling condition foresees that the enabling signal Sa is absent if the combing machine is accelerating, for example in an initial time interval from the start of the machine, of 10 seconds for example.
- the enabling unit 80 is operating analogue to a timer, which sends the enabling signal Sa only after the predetermined time interval after the start of the machine.
- a second enabling condition foresees that the enabling signal Sa is absent if the combing machine is performing the cleaning of the circular comb 14.
- the enabling unit 80 is operating analogue to a timer that sends the enabling signal Sa only after the predetermined time interval after the start of the machine, because it is possible to determine the in which the said cleaning will take place from the start-up.
- the enabling unit is operating analogue to a switch.
- the enabling unit comprises a
- the control device comprises a first AND logic gate 90 that sends a blowing signal Ss to the solenoid valve 40 if the position signal Sp and the enabling signal
- the solenoid valve 40 provides for the discharge of the blow when the blowing signal Ss is received.
- the opto-coupler is suitable to transfer the position signal Sp from the sensor 60 to the AND port 90, by means of an optic route, only in the presence of the position signal Sp; in the absence of the said signal the sensor and the AND port are uncoupled.
- the combing machine comprises a plurality of combing heads, each with its related pinching device, circular comb and rectilinear comb; the heads are assembled in two groups. For example, an embodiment foresees a combing machine with eight combing heads divided in two groups of four.
- control device comprises an additional sensor 60', positioned for example on the same rotating plate 70, but on the opposite face in relation to that of the sensor 60.
- control device comprises a further signalling element 62', positioned on the control disc 50, spaced in an angular manner to the signalling element 62, at 180° for example.
- control device comprises a further opto-coupler 100' and a further AND logic gate 90'.
- the enabling unit 80 is also connected to a further AND logic gate 90' and sends the same enabling signal Sa.
- a separate enabling unit is foreseen.
- the blowing device comprises a further solenoid valve 40', generally connected to the same compressed air supply 42.
- the first solenoid valve 40 is connected to the rectilinear combs 9 of the heads of the first group (for example, from the first head to the forth head), while the other solenoid valve 40' is connected to the rectilinear combs 109 of the heads of the second group (for example, from the forth head to the eighth head).
- the blowing of the heads of the first group and on the heads of the second group is performed in an out-of-phase manner, improving the efficiency of the compressed air supply.
- the position signal Sp 1 Sp' is emitted every number of combing cycles equal to the said transmission ratio.
- the position signal Sp, Sp' is emitted every forth combing cycle (and the further position signal Sp' is emitted in an out-of-phase manner in relation to the first position signal Sp).
- the signalling element 62 id connected to the comb shaft 16 (in this case the transmission ratio is equal to 1); sensor 60 is positioned on the rotating plate 70 angularly adjustable in relation to the comb shaft
- filtering means 82 are foreseen, with input positioning signals Sp, Sp'; the filtering means are suitable to allow the first signal Sp or the second signal Sp' to alternately pass on each turn of the comb shaft.
- the opto-coupler allows transmitting the position signal from the sensor to the AND logic gate at high speed, while electrically maintaining the components isolated when the position signal is absent.
- control device comprises input means 130, for example comprising a keyboard and a monitor, suitable for inputting a predetermined speed value at which the combing machine to work and blowing is optimal.
