Description
The present invention relates to the storage of representative type yarn and the feed unit of defined in the preamble of claim 1.
In this class yarn storage and feed unit, switching device is used for controlling the transmission device of bearing supply storage yarn.In case the storage amount of thread reduces to minimum, the storage yarn increases again.At last up to the maximum yarn number of turns, so above-mentioned transmission device is ineffective again.This control process also can be finished in such a way: storage yarn supply is to carry out under the actual situation that does not reach these two numerical value in that the latter is remained between the minimum and maximum yarn number of turns.When reaching its maximum or the minimum yarn number of turns as if storage yarn feeding amount in the case, this is counted as a kind of performance and cause that switching device not only makes the transmission device of yarn storage and feed unit inoperative of lacking of proper care, and makes the relevant mechanical transmission mechanism that therewith turns round inoperative.Yarn and feed unit with storage body, usually adopt the finger-type detective cell, this detection original paper is fixed on the outside of memory bank, and the one end stretches into the axial notch of this memory bank under the elastic force effect of spring, this detective cell or with switching device synergy, or itself has the contact, is used to produce a signal with the secondary contact concerted action.When the storage amount of thread is increased to certain value, detective cell generation deflection, thus produce a signal-to stop the further increase of storage yarn.There is following shortcoming in this known devices: detective cell Volume around coil on apply certain force of strain, cause each unwinding yarn circle is produced an obvious appreciiable pull-back forces.Yet concerning yarn processing or textile industry, the most important thing is: storage line tension force is not only very low, and constant substantially, and this is the main purpose of yarn storage and feed unit.When unwinding yarn, can produce the air ring of feeding, but owing to the formation that detective cell hinders air ring is being put on its surface.Another shortcoming of known devices is this detective cell or their spring force, all must abide by the kind of feeding yarn and performance and thickness of yarn and regulate respectively, and this requires quite complicated structure.These situations cause people to adopt optics more and more or say optical sensing means, can not contact under the situation of yarn in reality, and it is detected.A kind of with regard in these devices directly is mapped on the fixed reflection surface on the memory bank a branch of light, so that by its reflection, monitor light intensity of this folded light beam or the like then.Yet, a monitored so strong and actv. signal take place consistently, that is very difficult.
Therefore, an object of the present invention is yarn storage and feed unit for a kind of afore mentioned rules is provided, in this device, the control of storage amount of yarn and monitoring are to finish under the situation of not disturbing unwinding yarn from the memory bank.
The feature of the present invention that characteristic proposed according to by claim 1 just can reach this purpose.
These features have guaranteed to adopt the detective cell that a weight is extremely light and be easy to move, this element is vulnerable to pollution not in operation, and provide such advantage: it can not disturb the unwinding of yarn and Volume to get significantly, because stretch out at detective cell on this position on memory bank surface, yarn is mentioned mobile from the surface of memory bank above detective cell, perhaps bigger distance in the detective cell front is mentioned yarn successively from the surface of memory bank; And on another position, under a very weak elastic force effect, detective cell extend to mutually concordant with the memory bank surface or even the indentation memory bank in, thereby in fact do not have the problem relevant with yarn.This detective cell is any contact of direct drive or switching device not, so that it does not almost apply significant power to yarn.On the other hand, end instr is to any displacement response of this detective cell, and produces and indicate the reaction signal of detective cell displacement, thereby shows that storage line quantity becomes too big or too little, and do not have actual contact it.
Claim 2 has proposed an advantageous embodiments.Short range starter (Proximity initiator) is for example to the changes of magnetic field response that itself produced, for the displacement of surveying detective cell produces signal.Industrial existing short range starter positional change even is extremely sensitive, thereby can be contained in from place enough far away, memory bank surface.So that this class short range starter of motion that does not disturb yarn can be ignored to not being located immediately at other lead in its measurement range or the influence of magnetizer element.
Claim 4 proposes a kind of alternative embodiment easily, and wherein each displacement of detective cell causes that magnetic field position changes, and detects the variation of magnetic-field intensity by end instr, and the result produces a signal.
Can an obvious prior feature by claim 5, because the return movement of detective cell is not subjected to any external force effect, and screen resilience can maintain atomic little value, thereby helps detective cell to overcome this screen resilience, moves on to the another location from an one position.Like this Volume around the yarn circle on only acted on an inappreciable very little power so that do not influence unwinding yarn tension force or continue Volume around the storage yarn.
Claim 6 has proposed a further advantageous embodiment.Detective cell center of oscillation axle can be positioned at comparison near the surface of memory bank, so that the mass concentration of detective cell that comprises permanent magnet is near this axle, thereby makes detective cell be easy to move.This embodiment advantage is: this kind oscillating motion causes the oscillating motion of permanent magnet field-as a kind of sudden change and the great variation of magnetic-field intensity, detected by end instr.With under the situation of spring leaf, can determine tilting axis as each end, the result under the condition of a long horizontal lever, only requires a small power effect concerning each end movement.
Can obvious another advantageous embodiments by claim 9, the displacement of detective cell Return-ing direction is not by mechanical force in this device, but utilizes magnetic force.This magnetic force can realize that it is very small that detective cell moves required starting power from its position easily with a kind of like this mode, and to Volume around the yarn circle have corresponding favourable influence.
Claim 10 has proposed another alternative embodiment.In the case, Volume around the yarn circle detective cell is moved on linear direction, detect the weakening result of magnetic-field intensity by end instr, thereby produce a signal.Detective cell can be contained in the little opening of memory bank, obtains the protection that avoids making dirty easily.
Claim 11 proposes another alternative.In the case, there is not the fixing axle that waves in the detective cell in memory bank, and detective cell then maintains a unstable balance state by screen resilience, state thus, it also can owing to around the effect of yarn circle be moved toward another stability.Detective cell is an ellipse garden dish, when making it be in the second place, no longer stretches out the surface of memory bank.
As a possibility, claim 12 has proposed an adoptable suitable embodiment.In the case, the step of guide rail causes detective cell to stretch out the memory bank surface in an one position respectively, and does not stretch out this surface in its another location.
In this respect, it is favourable that application rights requires 13 device, obviously is just to be determined from the outset as the end position of in the case detective cell, and the magnetic field position of permanent magnet also will accurately detect by end instr.
The feature that is proposed in the right 14, for guarantee Volume around the yarn circle to make detective cell move on to the another location from a position soon be important.
The end instr of defined can be checked the very little variation of magnetic-field intensity in the claim 15.
The embodiment of claim 17 provides special benefits, owing to cancelled independent retracting spring, or cancelled the independent permanent magnet that detective cell is returned, but utilize magnetic interaction between detective cell and two permanent magnets of swing element, thereby produce the return force of these two elements.
The embodiment that claim 18 proposed has found it is particularly advantageous in force.Detective cell is a simple shape, so that cheap, and the installing and locating in memory bank is convenient, has also guaranteed the rapid reaction to any contact of yarn coil.The interference of dust may influence the work of detective cell, adopts the measure of claim 19 to avoid effectively.
The embodiment of claim 21 provides following special benefits: each detective cell monitoring storage line limit separately, so that produce two kinds of unlike signals-can be used as analog signal conditioning or, thereby control other member as digital signal processing.
Another advantageous embodiments is stipulated by claim 23.In this example, the displacement of detective cell is used as reflection and directly penetrates thereon a branch of light by external light source, compares with traditional optical measuring system.This provides following advantage: can adopt a very strong light beam, and the reflection of this light beam produces a very strong signal, owing to need to survey the Strength Changes of folded light beam-for some reason before receptor does not resemble, it may be quite weak, but only distinguishes that still there is not the reflected light of a beam intensity in existence.Therefore, this optical measuring system is than known system in the past, and is obviously sensitiveer, more reliable.
A prior feature is proposed in the claim 24.Receptor is configured on the path that the light beam under the detective cell displacement situation gets, and on detective cell moved to a bit, this light beam was mapped to receptor, and the signal of Chan Shenging is effective and powerful by this way.
In a kind of alternative concrete device that in claim 25, is disclosed, when detective cell was in one of two positions being replaced, light beam was mapped on the receptor, when detective cell is removed this position, folded light beam no longer is mapped on the receptor, provides the clearly indication of this displacement simultaneously.
Referring now to accompanying drawing, whole embodiment of the present invention is described by way of example.In the accompanying drawing:

In the embodiment of Fig. 5 a and 5b, minimum and maxim detector 18c, 19c respectively comprises an ellipse garden shape detective cell 39.This element has the permanent magnet 29 that is positioned at its center.By the screen resilience of another permanent magnet 38 generations as each detective cell 39.The former polarity and latter's polarity are antithesis.Shown in Fig. 5 b, the width of each detective cell 39 is quite big, makes on its axial guidance 43 that can be constituted in the groove 16 of memory bank to roll reposefully.Suppose that permanent magnet 38 makes detective cell 39 arrive a upright position, this position configuration example as, ellipse garden major axis rill rooved face part 40 is stretched out memory bank surface 15, so that coil engagement with yarn 27, the detective cell 39 of result's (for example) minimum detector 19a, ellipse garden major axis tilt to forward to the mutually concordant position in its surface portion 40 and memory bank surface 15.Guide rail 43 can be installed braking element 41 and 42, with the end positions of absolute each detective cell of qualification.
In the embodiment of the minimum detector 18b shown in Fig. 6 a and the 6b, detective cell 46 is the garden dishes with certain width, so that permanent magnet 29 entirely is wrapped in wherein.This memory bank has the guide rail 44 of band step 45, and detective cell 46 can be made following mode along this guide rail and move: its position makes it stretch out surface 15, and in the another location (shown in the dotted line), makes it mutually concordant with surface 15.Produce as the position that allows detective cell 46 in its withdrawal memory bank to the screen resilience that stretches out the memory bank outer surface position by second permanent magnet 38.Guide rail 44 is also made and is had drg 41 and 42, in order to determine the end positions of detective cell 46 reliably.Detective cell 46 also can be made into to have groove 48-, and it cooperates in such a way with tooth 47 on the guide rail 44: to avoid the rotation of detective cell 46 with respect to guide rail 44.With regard to the change of this embodiment, detective cell 46 certainly is a globosity.
In above-mentioned several embodiment, for producing the screen resilience of detective cell, also available spring replaces second permanent magnet 38.
The embodiment of minimum detector 18a shown in Fig. 7 a and the 7b comprises that still a block detective cell 28-entirely encases-piece permanent magnet 29, and is contained on the bearing portions 37 of memory bank, so that do oscillating motion around axle 36.Pin 64 stretches out from the bottom surface of detective cell 28, connects with extension spring 49, and the other end of extension spring is fixed on the interior set pin 50 of memory bank.49 pairs of detective cells of extension spring 28 produce screen resilience.Memory bank has suitably disposed the brake equipment (not shown), to limit the terminal position of the detective cell 28 shown in Fig. 7 a reliably.
In the embodiment shown in fig. 8, minimum and maxim detector 19f, 18f, each still comprises a block detective cell 28, but its position is with respect to the direction of the yarn coil reach of yarn 27 and the position represented with respect to previous embodiment, rotated 180 °, thereby its slope 32 faces yarn circle reach direction.The top of each detective cell 28 has the angle, garden, with 51 expressions.
Two detective cells 28 are installed in the radial cavities 52 of memory bank, and sliding in the baffle plate 53 of guiding by means of push rod 54 moves radially detective cell 28.Each push rod 54 is processed into a thicker head 55 in the bottom of baffle plate 53, for being connected with compression spring 56, the other end of spring 56 is supported on the areal of support 57.Cavity 52 is with a film 58 leak free in addition externally.
The storage yarn that minimum detector 19f has been reeled in Fig. 8 is pressed onto such degree: its top 51 is actual to reach mutually concordant with surface 15, and head 55 has broken away from baffle plate 53.On the other hand, the detective cell 28 of maxim detector 18f, be to arrive such position owing to compression spring 56 rebounds: its head 55 contacts with baffle plate 53, and surface 15 is stretched out on slope 32, thereby film 58 is stretched upwards.
Embodiment shown in Fig. 9 a and the 9b still comprises a block detective cell 28, and it entirely encases permanent magnet 29 and is installed on the bearing portions 37 of memory bank, so that do oscillating motion around axle 36.Though expression can be equipped with another permanent magnet 38 in Fig. 9 a, in order to produce screen resilience, this second permanent magnet is not requisite in the present embodiment.
This is because the end instr of aiming at detective cell 28 this moment is a swing element 58, and is identical with the polar configurations of the permanent magnet 29 of detective cell 28, and it has comprised whole permanent magnet 60.Swing element 58 has a upright arm 59 that matches with photoelectric sensor 63.Swing element 58 is installed on the bearing portions 62, so that do hunting motion around the axle 61 that is parallel to axle 36.
Two permanent magnets 29 are inhaled also in such a way each other mutually with 60, mate with each other: as the detective cell 28(of minimum detector 18g Figure 10) when swinging, swing element 58 also will correspondingly be swung around axle 61 together with its permanent magnet 60, when the magnetic line of force of two magnet tendency remains on the parallel lines, then make arm 59 lose contact with the photoelectric sensor 63 that produces signal.Because the mutual action of two magnet 29 and 60, the pressure one on swing detective cell 28 disappears, and they just get back to the position shown in Fig. 9 a simultaneously at once.
Figure 11 a to 11c represents to be used for the embodiment as a kind of optical system of maxim detector 18.
In Figure 11 a maxim detector 18 comprise a detective cell 28 ' ", this element by spring leaf 66 ' resilient end 65 constitute, its mode (is not represented) below 15 in the surface that is fixed on memory bank.When reed relaxed state I, end 65 is the top of protuberate 15 obliquely, and under the condition of loading that the coiling coil is arranged, (promptly being assumed to be the position II) is concordant with surface 15 substantially.End 65 has a reflecting surface 74, for example a minute surface.What place this device fixed part is the end instr 20 that photosensor forms "; for example photoelectric transducer; with light source 72(photodiode for example) match; for example a kind of infrared beam of light source 73 emission light beam 73() be mapped on the reflecting surface 74 of end 65; so that at detective cell 28 " ' the position I, by the reflection of direction 73 I.End instr 20 " is direction 73 I of aiming at this reflected light rays.When end 65 moved on to the position II owing to the coiling coil, the reflected light of light beam 73 was along direction 73 II, thereby no longer was mapped to end instr 20 " on.
In the embodiment of Figure 11 b, light source 72 entirely is included in end instr 20 " ' in, in the case, except that light source, end instr also comprises the receptor of a light beam 73.End instr 20 " ' light emitted be substantially the light beam radially 73 of memory bank, thereby this light beam is perpendicular to surface 15.In the I of the position of end 65, light beam 73 reflects along 73 I directions, and along this direction, light beam is penetrated less than end instr 20 " ' on.But be moved to the position II when end 65, even during its concordant with surface 15 substantially position, light beam 73 is along the radially reflection perpendicular to surface 15, so that light is penetrated fully at end instr 20 " ' on.Detective cell 28 " ' be used as maxim detector 18 in the case again, thereby on its second place II, be used for producing signal, in this position, light beam 73 is reflected to end instr 20 along 73 II directions " ' on.
In the embodiment of Figure 11 c, detective cell 28 " ' be block, be mounted for and moving radially with respect to memory bank surface 15, it have a slope 74 ', storage line yarn circle can be wound thereon.Slope 74 ' or, perhaps come reflected light by the embedding element that reflects that is equipped with by itself.Detective cell 28 " " is formed the part of maxim detector 18 again.Light source 73 is installed in the fixed part of this device, and its light beam that sends 73 is along substantially perpendicular to the surface 15 radially, direct projection to the surface 74 of detective cell 28 " " ' on.On the position I of detective cell 28 " ", this detective cell stretches out surface 15, and light beam 73 is along being reflected on the end instr 20 on direction 73 I, and end instr is again a photodiode or a photosensor signal producer.In the position II, detective cell 28 " " is mutually concordant with surface 15 substantially, and this folded light beam is moved down by past as shown in the figure, causes along the reflection of direction 73 II and penetrates at end instr 20 " on.
At Figure 11 a in the embodiment shown in the 11c, directly be mapped to the light beam on the detective cell, in fact can aim at either direction, just be noted that: detective cell when given position the reflected light beam on end instr, and in any other position of detective cell, folded light beam is not penetrated on end instr.For this reason, detective cell is owing to moving that the coiling coil is produced, with respect to surface 15 or with respect to what direction of memory bank axis, (or radially, or to be parallel to memory bank or to be parallel on the axis of coiling coil around one be unessential), as long as guarantee: the displacement of detective cell causes corresponding folded light beam displacement, and the latter can be detected by end instr and produce a signal just.
