Description
Technical field
Introduction according to the 1st, 11 and 12 of Patent right requirements independently the present invention relates to housing, has installation a pair of roller within it, relates to the drafting system with the type housing, and relates to the weaving loom with corresponding drafting system.
Background technology
In textile technology, drafting system is used for the drawing-off or the traction of ribbon in spinning machine.After the traction operation, the ribbon that draws in drafting system is spun into yarn by the weaving operation.Adjusting or the adjustability that the present invention relates to drafting system described below, the i.e. adjustability of drawing-off distance in the drafting system.Drafting system comprises at least two pairs of rollers, but preferably includes three pairs or four pairs of rollers.Operation is passed the ribbon of drafting system by the right different rotation rates institute drawing-off of described roller.Draw continuously or drawing-off between two pairs of rollers, promptly carry out in the zone between the clamping line of two pairs of rollers.Distance between such two clamping lines is also referred to as clamping or clamping distance.The drawing-off zone is positioned at this clamp distance, and in this zone, the fiber of ribbon draws each other.Generally use three roller drafting devices with preliminary draft zone and dominant draft zone.For the optimum waveguide traction and the best traction that realize fiber in drafting system, the clamp distance in single drawing-off zone must be adjusted to the fibre length of pending fiber.In the drawing-off zone, best clamping or clamping distance are longer than pending longest fiber (exceeding about 2mm) slightly.For clamp distance being adjusted to the optimum value of fibre length, but drawing-off zone step-less adjustment or can regulate with very little step-length (step-length is about 1mm) at least correspondingly; This is particularly useful for the preliminary draft zone.Because under the situation that does not have other outer fiber thread-carriers (as apron), in the preliminary draft zone, carry out 1.1 to 5 times real traction or drafting process, so the adjustability particular importance of clamp distance in the preliminary draft zone.For dominant draft zone (having about 10 to 100 times drawing-off or distraction procedure), the adjustability of clamp distance is favourable equally, even in this case, the fiber thread-carrier is guaranteed by the apron of common existence.Yet, in this case, if clamp distance arrives between maximum five step-lengths adjustable just enough at two.
When regulating clamp distance, right two axles of moving roller (in this respect, such as referring to DE 1 123 959 or DE 1 122 885) normally common (as utilizing the ring spinning drafting system) always.In other words, driving roller moves together with the top roller that is subjected to load.These devices have shown the disadvantage of traditional drafting system.When changing pending fibrous material, the right adjusting of roller needs extensive work.If in the time of must changing dominant draft or hauling distance, above-mentioned situation is especially suitable, because in this case, must replace with, descend apron and all upper leather ring retainers.
Though just at the single apron drafting system of early stage use, DE 489 810 discloses a possibility equipment for this problem.The disclosed input roller of regulating is installed on the guiding vehicle frame among the DE 489 810, and presses to the bottom roll that belongs to it by screw.Because the simple designs of single apron drafting system and lack upper leather ring, the adjusting of top roller is carried out easily.
For the duo roth system in modern times, the adjustability of the type is no longer possible, because top roller has apron.
For the device according to DE 1 122 885, two rollers of input roller centering all move.Can from describing, it find out this point, because this device is used to handle staple fibre and long stapled fiber, promptly from the cotton to the wool.Because in order to obtain such well-formedness, very different clamp distance must be able to be regulated, except the point of adjustment that discloses upper and lower roller, other content is not disclosed in the literary composition.Using this single apron drafting system to handle staple fibre and long stapled fiber no longer may in modern machines.The skin circle must be arranged, for the speed (speed is higher than 100 meters/minute) of current high speed drafting system, described skin circle will begin chatter for this reason.
EP 362 477 A1 disclose another and have been used to regulate the right device of a plurality of rollers.Yet disclosed therein device relates to so-called drawing-off or hauling machine.Drawing-off or hauling machine do not comprise any apron, because they only need to realize considerably less drawing-off.Yet, thereby they at delivery roller to locating to have very high transmission speed up to 1000 meters/minute.In order to ensure clamping or be clamped in this at a high speed down and still enough for big fibre weight, the contact pressure at the clamping line place between two rollers is also very high.Because a large amount of grinding work has taken place at the apron place, the result makes apron overheat because bad heat radiation, so for the high speed and the high pressure of the type, do not use apron.
Summary of the invention
Therefore, the present invention is based on the problem (output speed is higher than 100 meters/minute) of the adjustability that improves Modern High-Speed drafting system clamp distance.
Feature in the 1st, 11 and 12 by Patent right requirement has independently solved this problem.
Claim and below description in, mention " bottom roll " and " top roller ".The title of two rollers normally commonly used in textile technology especially comes from the layout of drafting system, and it is level normally.Yet the space of drafting system and roller is arranged important anything but for the present invention.On the contrary, in the particularly preferred application possibility of the present invention, even know that the regulation drafting system is substantially for being arranged vertically.Therefore, should clearly note this fact: the term " bottom roll " and " top roller " that run through among the application should not explain with regard to its locus, they are restricted to " on " or D score.In general, term " bottom roll " can be regarded as and refers to the right cylinder of roller.It is preferably made by metal (for example steel)." top roller " has resilient coverings (for example rubber) usually.
Illustrated: especially for the high speed drafting system, clamp distance can be regulated by shifting axle, for yarn qualities or weaving result without any the unfavorable effect of determining.Therefore the adjusting of clamp distance has been simplified greatly.If only move a roller, retainer can be used for the roller that rigidity is settled, and when regulating, it does not need to change.This has also simplified adjusting.In order in adjustment process, to keep clamping or clamping force between two rollers constant, regulate the loading force of bite then be favourable if can automatic or manual.In order to make apron all have enough tension force in each position of regulating, apron can have a tensioning apparatus at the roller place of removable installation.If two rollers all have apron, each of two aprons can have a tensioning apparatus so.Yet, also possible: as especially,, can not use the apron tensioning apparatus as its result for the elasticity or the extendible apron that use.Even must not change apron because not having tensioning apparatus or elastic performance, still can realize saving the plenty of time, because have only a roller to be moved.
Can in the accompanying Claim book, find an advantageous embodiment of the invention and form.
Description of drawings
Hereinafter the embodiment based on the accompanying drawing representative explains the present invention and notion of the present invention.Yet, should know and notice this fact: the embodiment that the present invention and notion of the present invention are not limited to show in the example.Accompanying drawing has shown:
To regulate roller right according to of the present invention for Fig. 1;
Fig. 2 roller regulated with apron tensioning apparatus according to the present invention is right;
Fig. 3 is used for according to the right housing of roller of regulating of the present invention; With
Fig. 4 has the yarning part of the weaving loom of drafting system, and it has shown that to regulate roller right according to of the present invention.
The specific embodiment
Fig. 1 has shown according to a pair of roller 2 of regulating of the present invention.This roller is installed in the suitable housing naturally to the roller in 2, though observe for convenience, housing does not show in the drawings.Roller comprises that to 2 bottom roller 4 and 5, two rollers of top roller are being called the place contact of clamping line 6.The structure of napex roller 5 is rigidity.On the contrary, bottom roller 4 is installed to such an extent that can move around the axis of top roller 5, as a result clamping line removable (referring to the position of dotted line among Fig. 1 and arrow demonstration).As result's (referring to arrow) that bottom roller 4 moves, clamping line 6 and consequent from front roller to can shortening or prolong to the clamp distance of rear roller to (not shown).In order to make bottom roller 4 install to such an extent that the top roller 5 installed for rigidity is axisymmetric, do not provide adjusting for top roller 5.As a result, not only readjust and to carry out quickly, and installation top roller 5 in design also can be simpler.In addition, the right adjustability of roller according to the present invention allows to use single retainer 9 and single top apron.Up to the present,, not only need to move two rollers, and need to change apron and retainer 9 (in order to be adjusted to new clamp distance) for adjusting device according to prior art.Because the fact that roller 5 rigidity are installed, the requirement of this replacing is no longer suitable, and the result can realize saving the considerable time.
In Fig. 1, apron 8 is applied to two rollers.Apron comes tensioning by counter-rotating cross bar 10 or retainer 9.For the adjustability of bottom roller 4, as directed, the apron 8 of bottom roller 4 must be tensile, maybe must come tensioning by suitable tensioning apparatus (referring to following Fig. 2).As previously mentioned, top roller 5 is installed (being that its axis is not removable) with rigid manner.Yet according to the present invention, the stiff shaft of top roller 5 can move in plane 7, and plane 7 is formed by two axis of described roller.If treat drawing-off or the fibrous material by the clamping line at clamping line 6 places (charger that can be used for this purpose is shown in Fig. 3, hereinafter will describe) push in constant and uniform mode, then the removable installation of the type will gear to actual circumstances.Have this effect with this mode movable axie: the skew of top roller 5 will can not cause any of clamping line 6 to move.
Fig. 2 shown according to the present invention and according to the roller regulated of Fig. 1 to 2, provide an extra apron tensioning apparatus 13 at this.This apron tensioning apparatus 13 is particularly useful for stiff or does not have enough flexible apron 8, to compensate the different clamp distance length that cause owing to elongation.The apron tensioning apparatus 13 that shows can be designed as tensioning spring.Yet other tensioning apparatus also are possible.If do not have enough elasticity certainly, the apron that is necessary for the top roller provides such tensioning apparatus (not shown).If there is no elastic characteristic or suitable tensioning apparatus, according to the present invention, the bottom apron also can be changed simply.
According to the demonstration among the present invention, especially Fig. 1 and 2 of describing so far, the roller 5 that rigidity is installed or can only be moved in plane 7 has apron 8, and is dispensable for the present invention, though shown apron in the drawings.
