Head 3 has gradually thin shape on the direction of resting position R, and wherein, head preferably has the cone angle between 5 ° and 120 °, also more preferably will have the cone angle between 5 ° and 60 °.Cone angle is less, and obtainable clamping force is higher.But, if cone angle is chosen to be less than 5 °, there is the risk that head 3 keeps being inserted in clamping device 16,17.
Preferably, head 3 is formed by ceramic material.Bar portion 4 is formed by metal, is preferably formed by steel.
Find out in the diagram and for space reasons, multiple senser element 2 to be arranged in guide portion 7 with two parallel rows with missing one another.This arrangement of senser element can be suitably used for detecting by means of an independent detector the multiple senser elements existed in resting position.Detector is configured to grating for this reason and it is so arranged make detector detect whole row's senser element.Grating is so arranged for this reason, in the operating position of all the sensors part of this row, namely do not interrupt the light path of grating; But drop in its resting position iff a senser element, it enters into the light path of grating.Therefore, in the arrangement that all senser elements are in two parallel rows, utilize that only two detectors just can be enough.
Fig. 5 shows the side view being similar to Fig. 2 of alternative senser element 22, and it is only the shape of head 23 with the difference of the senser element used in fig. 2.Namely head 23 is configured with outside 23a, 23b of convex, and it is towards clamping area 16a, 17a of the convex of clamping device 16,17.The tangent line at 23a, 23b and the contact point place between clamping area 16a, 17a can regard the limit of cone angle as outside.Remaining partial response in the warp thread faciola monitor 1 of Fig. 1 to Fig. 4 embodiment and number with identical reference number equally.
Fig. 6 shows the side view being similar to Fig. 2 of another alternative design of senser element 32, and it is only the shape of head 33 with the difference of the senser element used in fig. 2.Head 33 is configured to plate-like in the part of its underpart, thus it has the outside 33a of the convex towards clamping device 34,35.In this embodiment, clamping device 34,35 is implemented as with square-section with the form of two parallel bars, and it limits flat clamping area 34a, 35a of inclining towards each other.The tangent line at 33a and the contact point place between clamping area 34a, 35a can regard the limit of cone angle as outside.Remaining partial response in the warp thread faciola monitor 1 of Fig. 1 to Fig. 4 embodiment and number with identical reference number equally.
Fig. 7 combines the clamping device 16,17 (it is become by two isolated clavates with circular cross-section) shown in figures 1-4 and shows senser element 32.In this embodiment, not only the clamping area of clamping device but also the surface of senser element with the structural plane of convex to each other.
Fig. 8 shows the schematic side view of circular loom 100.Figure 9 illustrates the detailed view of circular loom 100.Correspondingly with the right on circular loom 100 left side be furnished with bobbin cradle 101.Each bobbin cradle carries multiple warp thread faciola bobbin 102, and warp thread faciola K can carry out extracting from warp thread faciola bobbin individually and guide the round reed 105 of circular loom 100 by different commutation portions (such as reverse wheel 14) into.In addition, circular loom has master driver 103 and control device 104, and wherein, master driver 103 drives the movable element of circular loom 100, and control device 104 controls all functions of circular loom 100 electronically.The operation principle of this circular loom is well-known to those skilled in the art and does not therefore need further elaboration.The special feature of this circular loom 100 is that warp thread faciola monitor 1 according to the present invention is arranged in warp thread faciola K at warp thread faciola bobbin 102 and it is in the path of drawing between portion in circular loom 100.In the diagram of Fig. 8 and 9, warp thread faciola monitor 1 is arranged near reverse wheel 14.It is evident that resting position signal 6 apparatus for controlling of supply 104 of warp thread faciola monitor 1.If control device 104 receives resting position signal 6, it makes master driver 103 stop.Therefore circular loom 100 arrives dead ship condition and the warp thread faciola bobbin 102 of the replaceable sky of operating personnel, in the warp thread faciola bobbin of this sky, warp thread faciola K is finished completely, has lost its tension at this, and the senser element 2 be therefore associated again occupies its resting position and warp thread faciola monitor 1 has sent resting position signal 6.
But the independent coil that warp thread faciola K occurs once in a while drops to coil axes from its warp thread faciola bobbin 102.This is particularly related to the coil of the edge being arranged in warp thread faciola bobbin 102.Independent dropping of warp thread faciola coil does not have effect negative further, but the coil loosened is rolled out gradually.But dropping of warp thread faciola coil causes the temporary transient tension loss of relevant warp thread faciola.Be different from the situation that warp thread faciola bobbin 102 exhausts, in order to the misinterpret avoiding the tension of warp thread faciola K to lose in this case, be arranged to: when detector detected during the given time period in resting position, to there is senser element time, at this moment the detector of warp thread faciola monitor 1 just sends resting position signal 6.Do not consider temporary transient warp thread faciola tension fluctuation by the measure postponed, it causes senser element to be displaced in resting position or near resting position.This measure also can perform in control device 104 with software in the following manner, and namely so programming to control device makes it only when it is just reacted to resting position signal 6 when predetermined time, section received resting position signal.
Figure 10 shows the detailed view of the circular loom of Fig. 8, and wherein, warp thread faciola monitor 1 according to the present invention is directly placed on bobbin cradle 101 place.
