Abstract

A textile technology device having a signaling device (6) has a flashing circuit for displaying a defined operating state, such as a thread breakage. Said circuit comprises of a flashing LED (28), to which at least one regular LED (29) is series connected. The circuit arrangement is cost-effective and sturdy. It allows both optical signaling of an error state and an electrical signaling of the error state to a central control unit, which can analyze the power requirement of the signaling unit for detecting the error state. The central control unit can further distinguish between simple line short circuits, or other electrical error states, from a properly reported error, because the flashing circuit comprising the flashing LED (28) and at least one further regular LED (29) records a chronologically periodically changing amount of power, once the circuit responds.

Description

Textile technology equipment therefor with automatic flashing indicator

The present invention relates to a kind of textile technology equipment therefor (textiltechnisches Geraet), this textile technology equipment therefor is with signalling apparatus (Signalisierungseinrichtung), so that with the specific running state of signal transmission.

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 arranges yarn monitor at 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 interrupt by relevant circuit the operation of 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 within 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 textile technology equipment therefor according to claim 1:

The textile technology equipment therefor comprises the signalling apparatus 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; this device is to on-off element, and for example electric switch (form that for example is protective 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.The favourable part that has by the signal transmission (current stabilization contact) of opening to realize is, the inefficacy of signalling apparatus 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 protective tube contact switch as switch, when magnet was close, this protective tube contact switch was with its closing of contact.This magnet can for example be supported by the yarn sensory rod or be mobile.Be applied to magnetic field on the protective tube contact and also can depend on state to be monitored by other means and be carried out change, in order to fault is transmitted with signal.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, signalling apparatus 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 circuit series.Flicker LED automatically switches on and off its running current.By this circuit series, other LED is switched on and off by identical beat.Therefore, can realize on the one hand, obtain for example larger illumination angle on all required direction in spaces by means of a plurality of LED, also can realize higher brightness simultaneously.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 power that grips one's attention of running state to be instructed.The favourable part of circuit parallel is that it consumes almost constant running current generally.Therefore, the mode that running current itself can be simple and reliable and be used to the fault (for example yarn disconnection) of sustainable existence is passed to signal the control convenience of knitting machine or this knitting machine.Yet it also is attainable that this point is utilized above-mentioned circuit series.When employed signalling apparatus at the flicker off period when also absorbing certain steady 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 off period (when LED does not work).Even also can not ensure electric current in the glow phase (Dunkelphasen) at light-emitting diode like this, this electric current is informed the existence of the selected running state of central control unit (for example fault) with signal.

Also suitablely being, is the circuit series that comprises flicker LED and the common LED resistor that is connected in parallel, this resistor flicker LED not glow phase produce equally the load electric current.The electric current demand of textile technology equipment therefor also can be used as the sign of fault existence and is detected by the control circuit.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 failure of current of short time (for example being less than 1 or 2 second) is not judged as fault and is eliminated.

Preferably, the signalling apparatus upstream is connected with rectifier circuit (form that for example is lattice Ritz (Graetz) circuit).This allows signalling apparatus both can also can move under alternating-current voltage/AC voltage under vdc alternatively.Buffer condenser can be connected to lattice Ritz circuit downstream.This buffer condenser is charged to the voltage of being exported by lattice Ritz circuit, and voltage is flattened surely, in order to 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 magnitude of voltage that is positioned at the buffer condenser place.Therefore, high capacitance but usually not high voltage bearing cond (for example double-layer capacitor) can be used as buffer condenser.It is also referred to as " ultracapacitor ", and (if needed time) can have some farads high capacity.

Cond 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 ultracapacitor, even if then when the voltage supply failure of textile technology equipment therefor, signalling apparatus also can transmit relevant running state (the normally running state in bad order of textile technology equipment therefor) with signal.

Be supplied with alternating-current voltage/AC 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 double circuit ".If be present in the cond in this circuit---its electric capacity is enough low---then can be used for electric current is limited.Form thus the way circuit that is consisted of by considerably less element generally.

Alternative solution as above task, also can be set as follows, namely, the textile technology equipment therefor has the signalling apparatus that is used to indicate definite state, at this, signalling apparatus 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) the 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 glass preferably is similarly grey or white.

According to the description of following a plurality of embodiment, the feasibility of other embodiment and concrete favourable part thereof are apparent.Description is limited to aspects more of the present invention and other situation.Accompanying drawing is complementarity.Therefrom can obtain further feature.In the drawings:

Fig. 4 has shown the circuit diagram of signalling apparatus, its in the vdc branch road with switch, and with buffer condenser,

Fig. 5 has shown the circuit diagram of signalling apparatus, its between buffer condenser and light-emitting diode with switch, and

Fig. 6 has shown the alternative circuit diagram of signalling apparatus, and it is with villard's circuit.

In Fig. 1, shown the 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 adaptor union (K1emme) 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 adaptor union 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) signalling apparatus 6 that the back will be introduced is supplied with voltage by plug-in type electromagnetic contact 4,5.In addition, at least in a preferred embodiment, state in bad order (for example yarn disconnection) is informed the central control unit of knitting machine in the mode of give a signal 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 thereon intercept place is 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, as substituting of belt wheel 7,8, can also be provided with other driving element (for example one or more electrical motors).

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 conveyed round this thread 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 edge 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 control 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 side on oscillation.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 reed of mode that can magnetic is sealed in wherein.

Between belt wheel 8 and thread wheel 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 processed 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 slightly white 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 extraneous 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 such as its institute.

Part for the method for avoiding this false signal transmission is that signal lamp 19 (just as the back will at length be introduced) produces colored light, for example red light.With regard to the light that it sends, therefore the color of the light that signal lamp 19 sends 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 signalling apparatus 6.Two plug-in type contacts (Einstechkontakt) 4,5 belong to this signalling apparatus 6, have realized voltage supply to signalling apparatus 6 by plug-in type contact 4,5.This voltage supply can be vdc supply or alternating-current voltage/AC voltage supply.Wire 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 C/LOOP (Ring).Graetz rectifier circuit 23 flows to

corresponding wire

24,25 with wavy (wellige) vdc.Wire 21,22 belongs to the alternating-current voltage/AC voltage branch road 26 of signalling apparatus 6.

Wire

24,25 belongs to the vdc branch road 27 of signalling apparatus 6.In the suitable position of signalling apparatus 6, for example (for example, in wire 22) is provided with switch 18 in alternating-current voltage/AC 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 of its control position, it arrived response position (Ansprechposition), in this response position, and switch 18 closures.Alternatively, switch 18 can be arranged in the vdc branch road 27, for example is arranged in wire 24 or the wire 25.

Vdc 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 (in the mode with set time beat (Zeittakt)) when being applied in vdc glimmers.Required vdc provides by Graetz rectifier circuit 23.When alternating-current voltage/AC voltage being applied to 4,5 place, plug-in type contact, Graetz rectifier circuit 23 is as rectifier.When vdc being applied to 4,5 place, plug-in type contact, Graetz rectifier circuit 23 is as polarity reversal protector (Verpolschutz).

Described signalling apparatus 6 is worked as follows so far:

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

If yarn disconnects, then 16 rotations of yarn sensory rod enter response position.Switch 18 closures, that is, and its conduction current.Now, signal lamp 19 places have vdc.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 in 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.Signalling apparatus 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 circuit series upstream---the too high words of voltage (in the situation of not taking this way) that (for example) obtained from plug-in type contact 4,5.In addition, also suitablely be to be the flicker LED28 cond 34 that is connected in parallel.If the flicker of flicker LED28 operates in the situation of not taking this way can be disturbed by the vdc of existing pulsation (this vdc is provided by rectifier circuit 23), then this point especially suits.Preferably, cond 34 has relatively high electric capacity.For example, it can have the hundreds of microfarad.Occur at this cond 34 places only to be a little low loss in voltage of several volts by what flicker LED28 limited.Cond 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 vdc branch road 27 and in alternating-current voltage/AC voltage branch road 26.Therefore, even if at flicker LED28 not during the glow phase, signalling apparatus 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 cond 34 is connected in parallel on the circuit series that comprises resistor 33 and flicker LED.

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

Especially suitable can be cond 34 is connected between the

wire

24,25, and switch 18 to be arranged between cond 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 large---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 have for the double layer capacitor of some farads capacitance as cond 34 (with regard to for example can be used as such as it so-called ultracapacitor for), the time of illuminating of relatively growing that then after the knitting machine shutdown, also can realize signal lamp 19.

Fig. 5 has shown another modification.The circuit series that comprises switch 18 and flicker LED28 herein, the cond 34 that is connected in parallel.For them, relatively low electric capacity is enough.This cond 34 is used for being flicker LED28 supply running 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 circuit series that is comprised 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 cond (Umladekondensator) 36 and energy-storage capacitor (Speicherkondensator) 37.It is typically used as voltage double circuit.Yet enough in the low situation, its mode with Limited Current works, so that Villard rectifier circuit 35 limits the running current of signal lamp 19 on the whole at the electric capacity that recharges cond 36.

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.

Textile technology equipment therefor with signalling apparatus 6 has flashing circuit, is used to indicate definite running state (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 faulty condition in the mode of optics with signal on the one hand, and allow on the other hand to transmit this faulty condition 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 signalling apparatus.

In addition, central control equipment can separate simple short circuit or other electrical accident state faulty section that quilt is reported with as prescribed, 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 when response.This magnitude of current can be for example from zero significantly different two numerical value between change back and forth with this flicker frequency, perhaps can be zigzag.This current signal can be distinguished out with other signal that is interrupted being produced by short circuit, bad contact or circuit significantly.
