The specific embodiment
The basic functional principle of drawing frame is described according to Fig. 1 below.According to the example of prior art, many untwisted drawing frame ribbon FB quilts arranged side by side feed.Same possible is only to import a ribbon FB to drawing frame.The head of the trumpet 1 of one compacting fiber bar FB is set at the input of drawing frame.Also can adopt other compaction apparatus.By by the checkout gear 2,3 of roller to constituting, the compacting fiber bar FB ' that is made up of many single ribbon FB sends into a drafting system 4.Its drafting system 4 generally comprise three drafting units or roller right, carry out actual drawing-off betwixt.This roller to be the input roller to 5, middle roller is to 6 and output or supply with roller to 7, their rotate with the peripheral speed that increases successively.By such formation, its ribbon FB ' according to peripheral speed than drafted.By middle roller to 6 with supply with roller in 7 main drawing areas that form, an additional setting depression bar 8, it its ribbon FB ' is turned to and improve thus fiber particularly be not clamped in two rollers between the guiding of fiber (so-called unsteady fiber).Assemble and by apply the bar pipe 16 that power is rotated 13,14 inputs with the calender roller of measuring the band cross section by spring 15 by turning to roller 9 to go up through the ribbon FB ' of drawing-off at many strips guide (seeing section amplification figure).By after being arranged on the bar pipe 16 on the rolling disc 17 that rotates with angular velocity omega, its ribbon FB ' is with speed V
LFall into bar tube 18.
For balance strip material deviation on drawing frame shown in Figure 1, take out signal by checkout gear 2,3.Feeding ribbon FB ' between two detection dishes 2,3 wherein because detection of motion dish 3 is pressed on the detection dish 2 by pressure, can coil the size that 3 skew obtains ribbon FB ' cross section by detection.For example its detection dish 3 and an inductive pick-up 20 idols connect, its signal of sensor is a voltage signal, it at first is transported to memory 21, then be transported to evaluation regulon 22 again according to its time difference, wherein memory (FIFO memory, i.e. push-up storage) can will checkout gear 2,3 pass and drafting system 4 between path difference and time difference count.In this case, be implemented in the compensation of main drawing area material deviation, the adjusting rotating speed of its servo drive control planetary gear mechanism 24 by the rotating speed that changes servo drive 23.With the controlled output speed of the planetary gear mechanism that drives by main motor 25 drive the input roller to 5 and middle roller to 6 bottom roll.The supply roller that is driven by main motor 25 is Chang Su to the rotating speed of 7 bottom roll, has guaranteed the output of accurate estimation ribbon FB '.
In the cross section of Fig. 1, show the bar guide member that is exaggerated between drafting system 4 and calender roller 13,14.Its schematic embodiment is the drawing frame RSB D30 of known Lv Te company.Its supporting plate 30 has the side bearing bolt 36 that makes 34 motions (seeing arrow 37) of fibre guide mouth, makes fibre guide mouth 34 under stopping state, makes its fibre guide mouth 34 deflection forward above supporting plate 30.Its fibre guide mouth 34 will be configured as firm strip FB ' from the fiber or the ribbon FB ' of drafting system 34.The fiber nozzle component 35 of packing in fibre guide mouth 34, its ribbon FB ' passes therethrough.Connect a supporting member 32 that is fixed on the supporting plate at the strip direction of transfer, a strip head of the trumpet 33 is installed thereon.
Show its supporting plate 30 in Fig. 2-4 more exactly, wherein the part is provided with or is not provided with supporting member 32 and strip head of the trumpet 33.Its supporting plate 30 has a tapered opening 31, packs into wherein from top its supporting member 32.Particularly as can be seen from Figure 3, the direction of transfer of its strip head of the trumpet 33 aligned fibers bars and charge into the slit that forms by calender roller 13,14.In Fig. 3, only be shown in broken lines calender roller 14.
Its ribbon FB ' enters strip head of the trumpet 33 and by calender roller 13,14 compactings and obtain higher intensity thus.Needed sliver tenacity will guarantee the reliable doff of its strip and drop into (referring to Fig. 1) in the bar tube 18 well.
Not only strip may occur and stop up, and usually can not stop strip to stop up at bar pipe 16 inlets at fibre guide mouth 34.When product moves continuously, between calender roller 13,14 and bar pipe 16 inlets, can stop up a large amount of ribbons.
The invention solves this problem.In Fig. 2-4, be provided with a recess 39 at the downside of supporting plate 30, fix an optical sensor 40 therein.As shown in Figure 4, its optical sensor 40 has a transmitter unit 47 and a receiving element 48.In Fig. 4, an electrical connector 49 that is used for optical sensor 40 is shown also.No longer schematically provide it and be electrically connected circuit.Its transmitter unit 47 emissions are preferably also worked as the light beam reflex time on reflecting material that is light cone at light beam visible or that infrared wavelength is regional and are reclaimed signal.
One pneumatic means 41 also is set in recess 39, and it has a pressure air connector 43, a pressure air pipe 42 and an inflatable mouth 44 in the flow distribution direction, wherein the space in face of the surface of its inflatable mouth alignment light sensor 40 and the sensor sheet.Its pneumatic means 41 can be for example with mode work continuously or pulsedly and prevent that fiber from flying hair and falling sensor surface.
Its pneumatic means 41 is connected with optical sensor 40 with mechanical system advantageously, makes its pneumatic means 41 only to be fixed on the supporting plate 30, referring to Fig. 4 by bolt 45.Equally as can be seen from Figure 4, two bolts 46 of fixed light sensor 40 are arranged on the pneumatic means 41.
Its optical sensor is worked in such a way.The light path of its reflector element 47 is basic parallel with the ribbon direction of transfer that passes strip head of the trumpet 33 (referring to the arrow 38 of Fig. 3).Because hide from view at the back side, the ribbon FB ' of 40 detections of its optical sensor in light cone be measured length really.Its light cone is enough to cover calender roller 13,14, yet does not have to cover the rolling disc part under being positioned at.In trouble-free strip production process, there is not reflecting material to be positioned within the light cone of transmitter unit 47.But when the strip obstruction occurring before bar pipe 16, its ribbon FB ' overflows the side of bar tube inlet and enters described light cone.The reflection of the ribbon material that it is blocked is received and produces a signal of telecommunication by the receiving element 48 of optical sensor 40.Its signal finally makes machinery shut down by a knock-off gear.By shutting down, interrupt the conveying of strip, make that can not occur serious obstruction before bar pipe 16 or rolling disc 17 also is limited to the substandard products of ribbon in the limited amount scope thus.
Another embodiment at strip head of the trumpet 33 exit region strip clogging sensors has been shown in Fig. 5-7.Supporting plate 30 among Fig. 5 is with above-mentioned identical.Its strip clogging sensor 50 according to theory of mechanics work also mainly comprises three parts, i.e. supporting member 52, switch member 54 and deflection piece 58 for vertical structure substantially.In the recess 39 of supporting plate 30 downsides corresponding, by the bolt 53 that passes a hole from the supporting plate 30 upsides elastic supporting piece 52 that is cylindricality substantially that is spirally connected with Fig. 2-4 recess 39.Its supporting member 52 is made by non-conducting material.On the supporting member 52 of supporting plate 30 downsides, cover a bell metal switch spare 54, but it does not contact with metal support plate 30 under static state.The annular edge and the gap width between the recess 39 of the switch member of measuring at ribbon FB ' direction of transfer (referring to arrow 38) 54 are the 0.1-0.3 millimeter.Its gap width or switch are apart from representing with arrow 51 respect to one another.The lateral distance that switch member 54 arrives recess 39 sidewalls contacts with its sidewall to prevent bell wall greater than its switch distance.
Its switch member 54 has a centre bore in the bell-jar zone, and it is aimed at the blind hole on the supporting member 52.Fix an axle 55 in its hole, its another free end protrudes in bell-jar and withstands on the offset member 58 that is made of helical spring.By on axle 55 and helical spring 58, loading onto a shrink sleeve 57, make fiber fly the bung flange that hair does not contact helical spring 58 especially.When helical spring or offset member 58 skews, its switch bell-jar 54 is along with skew.In case skew surpasses an amount of determining, the top edge of its switch bell-jar 54 and following side contacts at the metal support plate 30 in recess 39 basal plane zones.
Its supporting plate 30 for example is resisted against on the negative electrode, and metal switch spare 54 is resisted against on the positive electrode.According to Fig. 7, electric insulation cable 60 passes the hole of horizontal distribution in the supporting plate 30.The terminal twisted wire 61 of its cable 60 is fixed to switch member 54 in electrical contact by a screw 62.Its offset member 58 from the upright position laterally offset, as mentioned above, makes switch bell-jar 54 and metal support dish 30 electrically contact when the strip obstruction appears in the sleeve pipe entrance area.The consequent signal of telecommunication is input to its machinery is shut down.After strip stopped up removing, its offset member 58 was got back to vertical initial position or resting position under the elastic reaction of supporting member 52 and offset member 58.This is disconnected being electrically connected between supporting plate 30 and the switch member 54 again.
In the replacement embodiment that does not illustrate, its supporting member 52 and offset member 58 can be integrally formed.Like this, the simple path that its offset member 58 provides has been simplified the operation proximity, and the supporting of combination and the spring constant of offset member can change in an advantageous manner according to its length.Preferred big than at the supporting plate far-end at the spring constant of supporting plate one end.
Because supporting member 52 plays insulating effect between supporting plate 30 and switch member 54, it is nonconducting.Its material can be different, for example rubber, elastomer or spring.In addition, its offset member 50 not necessarily uses spring to constitute, and for example can select flexible elastomeric material or other rigid material to substitute spring.In in the end a kind of situation, it is flexible that its supporting member 52 can be selected.Its offset member 58 also has a point surface to substitute shrink sleeve.
Mechanical type strip sensor of the present invention also can be used in other textile machine as drawing frame, as carding machine or combing machine (
) in.As described in the prior art, can also be used in the alternative contact of the induced signal that produces in the corresponding sensing unit current loop is switched on or switched off by two metalworks, produce stopping signal.
