Description

Regulate the device of web guider

The present invention relates to the fibroreticulate device of guiding on the spigot surface of a guide element, this guide element extends perpendicular to fibroreticulate throughput direction.

Several web guiders have been shown in Fig. 8 of EP-PS139236, and these web guiders respectively have different cross sections.A kind of arch web guider 5.3 for example has been shown in Fig. 8 c, in this guide, has crossed domes from the fiber web of drafter 4 outputs at a bigger width internal diameter and carry.According to application target, particularly consider the web guider that to select respective shapes under the situation of desired web width for use.

Particularly, on this machine, fiber web is exported to a transport platform by a plurality of output points, and then superimposed, therefore must adjust fibroreticulate width exactly.Through after this adjustment, need superimposed fiber web to stack together exactly on the one hand, on the other hand, under the situation that also has the part ribbon to exist, avoid in fiber web, forming the space.The space refers to and form empty zone in fibroreticulate breadth, thereby the continuous fibers that can't be implemented on the fibroreticulate whole breadth distributes.This space produces disadvantageous result in processing subsequently.The adjustment of web width also is very important for the machining cell of back, when especially needing a kind of fiber web sample of predetermined fabric width.

Can know by inference thus, adopt a higher adjusted value that fiber web is adjusted accurately, so that in the operation of back, form high-quality finished product (yarn).This adjustment must usually be carried out, because always change (for example new material) in the processing.In other words, with the device of being advised among the EP-PS 139236, the web guider shown in must replacing according to required adjusted value.Therefore, may need repeatedly replacement just can reach required result.This shows, need sizable power consumption and many deposits with web guider of varying cross-section structure.

Adopted a kind of adjusting device in another known Japanese Utility Model JP-U-6-47386, wherein the side guiding face of a guide plate can be regulated in its obliquity.But this device can only influence fibroreticulate two outside scopes.Can't be implemented in the even regulation on the fibroreticulate whole fabric width, particularly consider the formation in above-mentioned space.In addition, also have a kind of concave surface web guider, the fiber web fabric width is narrowed down, and the fiber web fabric width of element (for example drafter) output from preceding working procedure is strengthened with this guide.

Therefore, the present invention constructs a kind of such fiber web guide element based on following task, and it overcomes the shortcoming of prior art on the one hand, realizes a kind of adjustment of simple and best fiber web fabric width on the other hand.In addition, make people can abandon special-purpose side web guider, for example the sort of described in described Japanese Utility Model patent specification.This task is to solve like this, guide element constitutes an arch Crumple element, it is positioned at an adjustment plane perpendicular to fibroreticulate throughput direction, and guide element has guide in the scope at its two ends, and it is protruding to advance in the guide rail of support, also have, in the support at least one has a regulating element, is used for respect to throughput direction laterally at least one guide of bracket adjustment, and it is remained on adjusting position.

Can simply regulate according to material solution by the present invention.

Preferable is that guide element is made of an elastic deformable material.So especially, can simplify the holder device that supports guide element, and for example can further advise, a kind of simple stepless regulator is provided.

Because guide element is an elastic construction, regulating element can be regulated the bending radius of guide element by the pressure at guide element two ends.

Further suggestion enlarges the cross section of guide element, does not so just need other element to come side direction guiding guide element on throughput direction extraly.In other words, the cross section of guide element constitutes like this, makes the flexural strength ratio on fibroreticulate throughput direction big in perpendicular to the plane of fibroreticulate throughput direction.

The intersection in order to avoid guiding particularly, suggestion are provided with the guide in the protruding guide rail that advances holder device in the scope at the two ends of guide element.

Guide can be pin, bolt, screw or analog, and it can guide in the slotted hole of support.

Preferably, the regulating element that is used for adjusting guide element in holder device is installed like this, makes it apply a pressure in the end of guide element when regulating.

For the good result of secured adjusted, the suggestion regulating element is made of lockable bolt.

Preferably, guide element is made by a kind of plastic material.Can imagine that also director element is made by the combination of a kind of composite or a kind of some materials.The selection of material will be especially according to carrying out for forming the desired strain value of arch.

To point out further feature in the following description, and it will be explained in detail.

Fig. 1 one has the plane according to an equipment of the guide element of the present invention equipment,

Fig. 2 is the front view of an embodiment of this guide element,

Fig. 3 is a zoomed-in view (guide element is in and does not add stress state) of holder device shown in Figure 2,

Fig. 4 is the plan view of Fig. 3,

Fig. 5 is the view of another guide element embodiment,

Fig. 6 is a profile of A-A face among Fig. 5.

Fig. 1 shows the section of a lapper 1, this machine the same with described in our application of Swiss Patent formerly CH-1335/94.Feed plate illustrates to number 2, and superimposed fiber web V is transported on it from a unshowned lap former, to form finisher lap.Superimposed fiber web V constitutes by being deposited on together from each fiber web V1 of illustrated drafter cell S 1 and S2 output and V2 respectively.

Fiber web V1 and V2 are before being transported on the feed plate, always earlier by guide element 4 guiding.Do not illustrate from the process of fibre transportation band to each drafter cell S 1 and S2 conveying at this, this part can be selected from the application of addressing previously of Swiss Patent formerly.

In Fig. 2,, in other words, on the throughput direction S1 of fiber web V and S2, show in detail a this guide element 4 with front view.This guide element is made of an elastic rod 5, and its both ends E1 and E2 have reinforcement 6.Respectively having a pin 7, two pins in the scope of the reinforcement 6 of described end rabbets respectively in the slotted hole 8 on each holder device 10.Fig. 3 and 4 has provided the detailed view of this holder device.Holder device 10 respectively has two side fishplate bars 11, and slotted hole 8 just is arranged on these two side fishplate bars.Thereby bolt 7 passes slotted hole 8 from the both sides of fishplate bar 11.In addition, holder device 10 also has diaphragm plate 13, and it is connected to each other with two fishplate bars 11 on the one hand, is used to hold a nut 15 on the other hand.Nut 15 is fixedlyed connected with diaphragm plate 13.Also have on the diaphragm plate 13 one with concentric through hole 16, one bolts 18 of nut 15 from wherein stretching out, and screw in each nut 15.

As mentioned above, the guide post with spigot surface 20 5 shown in Figure 3 is in the state that does not add mechanical load, that is to say, and is just in time straight.Want to regulate imaging arch state shown in Figure 2, bolt 18 must be screwed in nut, thereby the end pin 7 placed on it of bolt 18 is moved inward.Form selected flexural strength according to the cross section according to guide bar 5, this bar can only be in one direction, i.e. bending in perpendicular to the plane 30 of fiber web throughput direction.Can regulate radius of curvature R by rotating bolt 18 suitably.By this adjusting, pin 7 moves in each holder device 10 in slotted hole 8, because holder device 10 is fixed on the feed plate 2, perhaps is fixed on the shell of drafter.The adjusting of the size of radius of curvature R affects the width B of the fiber web V1 (V2) of guiding on guiding plane 20.In other words, radius R is regulated more for a short time, fiber web by corresponding tightening force draw back just many more, thereby strengthened width B.

Figure 5 illustrates the another kind of form of implementation of guide element 4.This guide element itself is made of a rod (for example sticking plaster) 22, has a mild section 25 in bending range 24.Should the special employing of mild section cross sectional shape shown in Figure 6.Because this mild section has been arranged, when applying a pressure k on illustrated pin 7, this rod is perpendicular to the fiber web V1 bending of guiding in the above.In other words, by this layout, bending strength on perpendicular to the throughput direction of fiber web V1 than little on throughput direction.To the adjusting of support element with same or similar at the embodiment shown in Fig. 3 or 4.

In order to prevent that definitely adjusted good state appearance is loose in operation process, can on bolt, add locking nuts than 15 to nut.

Adjusting device also can be constructed like this, and the adjusting that makes guide element 4 is promptly carried out in the scope of end E1 and E2 only in a side of machine.Adjusting device can be expanded in many-side.The limitation that do not have when considering " fiber web " this notion, and be interpreted as the also bootable cotton-wool band of this device.
