Description

The textile technology equipment therefor that has automatic flicker indicator

The present invention relates to a kind of textile technology equipment therefor (textiltechnisches Geraet), this textile technology equipment therefor has recoil simulator (Signalisierungseinrichtung), so that transmit specific running status with signal.

Textile technology equipment therefor such as the thread delivery device (Fadenliefergeraet) of knitting machine, Yarn senser, yarn monitor etc. often is arranged in the knitting machine, and must be by knitting worker's monitoring.About this point, cicada from file DE-AS 24 58 884 is provided with yarn monitor on this textile technology equipment therefor, and this yarn monitor comprises electric switch.Indicator lamp is controlled via electric switch, when for example finding that yarn disconnects, this indicator lamp flicker.In addition, can be by the operation of relevant circuit interruption knitting machine.

If knitting worker must the many machines of monitoring, then during the flicker of an independent signal lamp usually and inconspicuous.Therefore, perhaps undesirable state (for example yarn disconnection) can not be found in long period of time, and that yes is unacceptable for this.Therefore, must seek better Signalling method.Yet this point should be implemented with minimum as far as possible cost simple and reliablely.

This task is realized by the textile technology equipment therefor according to claim 1:

The textile technology equipment therefor comprises the recoil simulator that is used to indicate definite (festgelegten) state.This state can for example disconnect for yarn.This point can be detected by yarn sensory rod (Fadenf ü hlhebel) or other suitable device, and this device is to switch element, and for example electric switch (form that for example is protection tube contact (Schutzrohrkontakt)) is handled.In principle, the manipulation of switch can be the closure that also can be the contact of opening of contact.Be by opening the favourable part that the signal transmission (current stabilization contact) that realizes has, the inefficacy of recoil simulator itself also can cause fault being transmitted (fault reliability Fehlersicherheit) with signal, and the advantage of the lower contact closure of nonserviceabling (alive contact during work) is its especially simple realizability.Can use the protection tube contact switch as switch, when magnet was close, this protection tube contact switch was with its closing of contact.This magnet can for example be supported by the yarn sensory rod or be moved.Affact magnetic field on the protection tube contact and also can depend on state to be monitored and be carried out change, so that fault is transmitted with signal by other means.Can for example cause this variation by the flow guide member that is supported in movable mode, for example, when the yarn of being monitored by the yarn sensory rod disconnected, the yarn sensory rod was with this flow guide member displacement.

Characteristics according to textile technology equipment therefor of the present invention are, recoil simulator produces the flash signal of optics in action the time.By the LED (Blink-LED) that will glimmer with at least one, preferred a plurality of common LEDs (Normal-LEDs) link with electric means and fetch the realization this point.Preferably use series circuit.Flicker LED automatically switches on and off its running current.By this series circuit, other LED is switched on and off by identical beat.Therefore, can realize on the one hand, obtain for example bigger illumination angle on all required direction in spaces, also can realize higher brightness simultaneously by means of a plurality of LED.Circuit is especially simple.The most requisite parts only are the series connection that comprises flicker LED and common LED.

Flicker LED and one or more common LED are connected in parallel.Especially when glimmer LED and a plurality of common LED were connected in parallel, common LED and flicker LED alternately glimmered.If they point to different direction in spaces, then can also realize the signal transmission of the especially good attracts attention of running status to be indicated.The favourable part of parallel circuit is that it consumes almost constant running current generally.Therefore, the mode that running current itself can the be simple and reliable and fault (for example yarn disconnection) that is used to continue to exist passes to the control appliance of knitting machine or this knitting machine with signal.Yet it also is attainable that this point is utilized above-mentioned series circuit.When employed recoil simulator at the flicker tempus intercalare when also absorbing certain stabling current, this point is especially feasible.This point can (for example) realize that by one or more buffer condensers (Pufferkondensator) this buffer condenser is emitted electric charge when LED lights, and receives a little electric charge at flicker tempus intercalare (when LED does not work).Even also can not guarantee electric current in the glow phase (Dunkelphasen) at light emitting diode like this, this electric current is informed the existence of the selected running status of master controller (for example fault) with signal.

Also suitable is, is the series circuit that comprises flicker LED and the common LED resistor that is connected in parallel, this resistor flicker LED not glow phase produce the load electric current equally.The electric current demand of textile technology equipment therefor also can be used as the sign that fault exists and controlled circuit detects.So, this resistor be used for preventing control circuit the flicker LED do not think that fault is excluded during the glow phase.

Alternatively, control circuit can be configured to, and the current interruptions of short time (for example being less than 1 or 2 second) is not judged as fault and is eliminated.

Preferably, the recoil simulator upstream is connected with rectifier circuit (form that for example is lattice Ritz (Graetz) circuit).This allows recoil simulator both can also can move under alternating voltage under DC voltage alternatively.Buffer condenser can be connected lattice Ritz circuit downstream.This buffer condenser is charged to the voltage of being exported by lattice Ritz circuit, and voltage is flattened surely, so that supply voltage and avoid beat entanglement (au β er Takt) for flicker LED when voltage hands over zero.Yet preferably, buffer condenser only is connected in parallel to flicker LED.This has reduced the voltage value that is positioned at the buffer condenser place.Therefore, high capacitance but not high voltage bearing usually capacitor (for example double-layer capacitor) can be used as buffer condenser.It is also referred to as " ultracapacitor ", and (time) if needed can have some farads high capacity.

Capacitor to comprise these LED or comprise at least this flicker LED circuit be connected in parallel guaranteed flicker LED the electron flare circuit not continuing to obtain voltage during the glow phase, in order to avoid the beat entanglement.If buffer condenser is a ultracapacitor, even if then when the voltage supply discontinuity of textile technology equipment therefor, recoil simulator also can transmit relevant running status (the normally out of order running status of textile technology equipment therefor) with signal.

Be supplied with alternating voltage if guarantee the textile technology equipment therefor, then also can use Villard (Villard) rectifier circuit to replace lattice Ritz circuit.It may also be referred to as " voltage-multiplying circuit ".If be present in the capacitor in this circuit---its electric capacity is enough low---then can be used for electric current is limited.Form the way circuit that constitutes by considerably less element generally thus.

Alternative solution as above task, also can be set as follows, promptly, the textile technology equipment therefor has the recoil simulator that is used to indicate definite state, at this, recoil simulator comprises at least one color LED (Farb-LED), and wherein, color LED is covered by (lichtdurchlaessig) housing section branch of printing opacity, and the color of this housing parts is different from the color of color LED.

Housing parts can be configured to light scattering (lichtstreuend), for example is configured to lacklustre (matt).Preferably, the color of this housing parts is consistent with the color of adjacent housing parts.As a result, the optics difference between (nichtleuchtender) signal LED that does not work and the signal LED that lights is especially remarkable.Total housing color is preferably grey or white.Equally, the color of lamp lens preferably is similarly grey or white.

In Fig. 1, shown thread delivery device 1 as the example of textile technology equipment therefor.Thread delivery device 1 comprises support 2, and this support 2 is provided with connector (Klemme) 3, is used for thread delivery device 1 is fixed to the machine ring (Maschinenring) of (for example) knitting machine.Usually also be provided with plug-in type electromagnetic contact (elektrischeEinstichkontakte) 4,5 in the zone of connector 3, this electric contact 4,5 is used for touching the cable that (for example) is arranged on the machine ring place of knitting machine.(for example being presented among Fig. 2) recoil simulator 6 that the back will be introduced is provided with voltage by plug-in type electromagnetic contact 4,5.In addition, at least in a preferred embodiment, out of order state (for example yarn disconnection) is informed the master controller of knitting machine in the mode of signaling by plug-in type electromagnetic contact 4,5 and the cable that touched thus.

Thread delivery device 1 have in Fig. 1, do not specifically illustrate, directed axle (Welle) vertically, this axle is rotatably supported on the support 2.Axle intercept place is thereon supporting one or

more belt wheels

7,8, and this

belt wheel

7,8 for example is used for by means of cingulum driving.Yet,, can also be provided with other driving element (for example one or more motor) as substituting of

belt wheel

7,8.

In current embodiment, thread wheel 9 is being supported in the lower end of axle, is twining a circle or preferred multi-turn yarn 10 to be carried round this delivery wheel 9.Yarn is directed to thread wheel 9 by yarn guide device (for example cable guiding device 11) through Yarn Brake 12 and yarn import eyelet 13.Yarn 10 preferably via the lower limb of thread wheel 9 with the mode debatching curried to knitting machine.The yarn that debatching goes out crosses one or

more outlet eyelets

14,15, is furnished with yarn sensory rod 16 between this outlet eyelet 14,15.This assembly is as yarn monitor.Yarn sensory rod 16 is remained in the operating position by yarn 10.If yarn 10 disappearance or too lax, then yarn sensory rod 16 for example under the effect of gravity or spring force or the power (for example magnetic force) that otherwise produces preferably to sideshake.At this, the electric contact 17 of its manipulation of switches 18 or other switching device.This switch 18 is for example for being the electric protection pipe contact switch of form that is in vacuum state or is filled with the glass tube of protection gas, and the affected contact of mode reed that can magnetic is sealed in wherein.

Between belt wheel 8 and thread delivery device 9 or also can be at other position signalization lamp 19 of thread delivery device 1.In current embodiment, this signal lamp 19 comprises transparent case, and this transparent case for example is the form of clear shell portion 20.In current embodiment, housing parts 20 forms the shell section of printing opacity, and this shell section is the general hollow tubular, also presents the shape of general toroidal convex or suitable in the time of if needed.At this, housing parts 20 is preferably handled through frosted, so that the light that will send mode with scattering on all direction of observations is launched.In another preferred embodiment, housing parts 20 is white slightly or colourless, so that it preferably is rendered as light color, for example light grey or lacklustre white under the state that is not illuminated.Therefore, this point is also because of following former thereby be preferred, that is, the ambient light (for example independent light beam of the general light source of the irradiation of the setting sun or luminance shortage) that generally points to that occurs for fear of accident cause housing parts 20 luminous and thus puppet produce in fact also non-existent signal.Especially preferredly be the color of housing parts 20 and the solid colour of all the other housings.This remaining housing can be similarly printing opacity, or preferably opaque as its institute.

Be used to avoid the part of the method for this false signal transmission to be, the light of signal lamp 19 (just as the back will at length be introduced) generation colour, for example red light.With regard to the light that it sends, therefore the color of the light that signal lamp 19 is sent preferably is different from the outward appearance aspect the color of housing parts 20 under the state that does not illuminate.

Fig. 2 has shown recoil simulator 6.Two plug-in type contacts (Einstechkontakt) 4,5 belong to this recoil simulator 6, have realized voltage supply to recoil simulator 6 by plug-in type contact 4,5.This voltage supply can be DC voltage supply or alternating

voltage supply.Lead

21,22 4,5 leads to Graetz rectifier circuit 23 from the plug-in type contact.Based on Fig. 2, this circuit comprises the diode of four polarization, and they link in closed-loop path (Ring).Graetz rectifier circuit 23 flows to

corresponding lead

24,25 with wavy (wellige)

DC voltage.Lead

21,22 belongs to the alternating voltage branch road 26 of recoil simulator 6.

Lead

24,25 belongs to the DC voltage branch road 27 of recoil simulator 6.In the suitable position of recoil simulator 6, for example (for example, in lead 22) is provided with switch 18 in alternating voltage branch road 26, and this switch 18 is handled by yarn sensory rod 16.As symbolically shown, this yarn sensory rod 16 for example is supported in swinging mode.Yarn sensory rod 16 carries at its free end and is suitable for by being placed on the part on the yarn 10, can for example be yarn eyelet 28 also perhaps.When bar 16 rotations exceeded the certain degree in its operating position, it arrived response position (Ansprechposition), in this response position, and switch 18 closures.Alternatively, switch 18 can be arranged in the DC voltage branch road 27, for example is arranged in lead 24 or the lead 25.

DC voltage branch road 27 passes through signal lamps 19 and closure, and flicker LED28 and one or more

common LED

29,30 belong to this signal lamp 19.Flicker LED28 comprises luminous diode element 31 and operation circuit 32, and this operation circuit 32 is periodically connected or interrupted electric current to this diode element 31.Do not need external cabling (Beschaltung) for this reason.Flicker LED28 (to have the mode of set time beat (Zeittakt)) when being applied in DC voltage glimmers.Required DC voltage provides by Graetz rectifier circuit 23.When alternating voltage being applied to 4,5 places, plug-in type contact, Graetz rectifier circuit 23 is as rectifier.When DC voltage being applied to 4,5 places, plug-in type contact, Graetz rectifier circuit 23 is as polarity reversal protector (Verpolschutz).

Described so far recoil simulator 6 is worked as follows:

Normally in service, DC voltage or alternating voltage are applied to 4,5 places, plug-in type contact.Yarn 10 remains on yarn sensory rod 16 in the operating position.Switch 18 is opened, i.e. its non-conducting electric current.Therefore, DC voltage branch road 27 is currentless.Signal lamp 19 does not work.

If yarn disconnects, then response position is gone in 16 rotations of yarn sensory rod.Switch 18 closures, that is, and its conductive electric current.Now, signal lamp 19 places have DC voltage.Flicker LED28 begins flicker.The

common LED

29,30 that is connected in series glimmers jointly with identical beat.If all LED28-30 for example are red, then under all the other situations, light in the mode that takes on a red color for housing parts 20 light color, that turn white.This point can be discovered by the user well.And illuminating obscuring between (Illuminierung) and can be excluded by other light source or the caused housing parts 20 of sunshine.Recoil simulator 6 can be carried out modification as illustrated in fig. 3.For example, at flicker LED28 and common LED 29, connect into resistors in series (Vorwiderstand) if 33 may be necessary or suitable in 30 series circuit upstream---the too high words of voltage (under the situation of not taking this way) that (for example) obtained from plug-in type contact 4,5.In addition, also suitable is, is the flicker LED28 capacitor 34 that is connected in parallel.If the flicker of flicker LED28 operates under the situation of not taking this way can be disturbed by the DC voltage of existing pulsation (this DC voltage is provided by rectifier circuit 23), then this point is especially suitable.Preferably, capacitor 34 has higher relatively electric capacity.For example, it can have the hundreds of microfarad.Take place at this capacitor 34 places that LED28 limited only is a little low voltage drop of several volts by flicker.Capacitor 34 does not charge in the glow phase at flicker LED, and thus, as long as switch 18 closures, electric current all continues to be kept in DC voltage branch road 27 and in alternating voltage branch road 26.Therefore, even if at flicker LED28 not during the glow phase, recoil simulator 6 also is passed to plug-in type contact 4,5 with the closure of switch 18 with signal, that is to say, as long as switch 18 closures are just carried out this signal transmission constantly.

Fig. 4 has shown another change.According to this change, if this optional resistor 33 exists really, then capacitor 34 is connected in parallel on the series circuit that comprises resistor 33 and flicker LED.

Another change can be that switch 18 is not to be arranged in the alternating voltage branch road 26, but is arranged in the DC voltage branch road 27.This point can occur in any position of ac voltage circuit (Wechselspannungskreises).

Especially suitable can be capacitor 34 is connected between the

lead

24,25, and switch 18 to be arranged between capacitor and the LED.The favourable part that this point has is, the capacitor stores electric charge, and this electric charge---when its amount is enough big---can allow, and also can transmit fault with signal even if work as when plug-in type contact 4,5 for example becomes no current owing to the shutdown of knitting machine.If use the double layer capacitor have for some farads capacitance as capacitor 34 (with regard to for example can be used as so-called ultracapacitor as it), the relative time of illuminating that then after knitting machine is shut down, also can realize signal lamp 19 than length for using like that.

Fig. 5 has shown another modification.Herein, the series circuit that comprises switch 18 and the flicker LED28 capacitor 34 that is connected in parallel.For them, relatively low electric capacity is enough.This capacitor 34 is used for being flicker LED28 supply working voltage during possible friendship zero process of the voltage that is positioned at 4,5 places, plug-in type contact.

Fig. 6 has shown another possibility that is used for run signal lamp 19, and it comprises the series circuit of being made up of flicker LED28 and common LED 29,30.Plug-in type contact 4,5 is connected with Villard rectifier circuit 35.The Villard rectifier circuit comprises two rectifier diodes, recharges capacitor (Umladekondensator) 36 and energy-storage capacitor (Speicherkondensator) 37.It is usually as voltage-multiplying circuit.Yet under the enough low situation of the electric capacity that recharges capacitor 36, its mode with the restriction electric current works, so that Villard rectifier circuit 35 limits the running current of signal lamp 19 on the whole.

As shown, switch 18 can be arranged on the entrance side with respect to Villard rectifier circuit 35, perhaps also can be arranged to connect with signal lamp 19.For example, switch can be arranged between LED or be in to their direct connection.

The textile technology equipment therefor that has recoil simulator 6 has flashing circuit, is used to indicate definite running status (for example yarn disconnection).This flashing circuit comprises flicker LED28, for this flicker LED28 is connected in series with at least one common LED 29.Circuit unit is with low cost and have a robustness.It allows to transmit malfunction in the mode of optics with signal on the one hand, and allow on the other hand to transmit this malfunction to central control equipment in the mode of electricity with signal, this central control equipment can be estimated with the detection failure state the electric current demand of recoil simulator.

In addition, central control equipment can with simple short circuit or other electric fault state with in accordance with regulations and the faulty section of being reported separate when responding, can be received in the periodically variable magnitude of current on the time because comprise the flashing circuit of flicker LED28 and at least one other common LED 29.This magnitude of current can be for example with zero significantly different two numerical value between change back and forth with this flicker frequency, perhaps can be zigzag.This current signal can be significantly by with differentiate mutually by short circuit, loose contact or other signal that circuit interruption produced.
