Description
Technical field
The present invention relates to a kind of cover plate bar that is used for carding machine, this cover plate bar has supporting body, two connectors and two front end components, and this front end component has at least one preferred two sliding area that limit the slide-and-guide surface.The invention still further relates to a kind of device that is used to be provided with the cover plate bar of carding machine.
Background technology
The structure of the cover plate bar of many type is known.
For example, described a kind of cover plate bar in the disclosed specification of DE10358257, wherein front end component is designed to pin.These sell the bottom of not using connector and directly being fixed to the supporting body of cover plate bar, and in this case, the downside of the pin that level is installed forms slidingsurface simultaneously, and the combing cover plate is leading by the sliding members on the side plate that is fixed to carding machine on this slidingsurface.When producing the cover plate bar, pin is placed on combing cover plate bottom for the special recess that is provided with of this purpose, is cast then.By the suitable setting of recess, the lower limb that can realize sliding area is that the free end of slide-and-guide surface and combing flat-clothing is the adjustment of the distance between the supporting body plane.Yet, this production method cost height, when the cover plate bar was changed card clothing subsequently, the front end component of former cast molding can not re-use.The Different Plane that produces owing to the processing of supporting body and delivery element for example slide-and-guide surface and supporting body plane the mutual alignment or mutually the inaccuracy of angle position eliminate by between the supporting body of card clothing and support member, introducing the intermediate layer.Usually, this intermediate layer is cast and forms.By this method compensate since make issuable from the slide-and-guide surface to the supporting body plane more than the obliquity on the axis be difficulty with complexity.
Adjustable cover plate bar also is known, for example, according to the disclosed specification of DE10046916, wherein disclose a kind of by a supporting body and two cover plate bars that front end component is formed, and have the adjustable that is combined in the front end component, and be this purpose, propose front end component is divided into two parts, the connection between these two parts or second parts itself are like this designs, make it possible to adjust the distance between the slidingsurface of supporting body and front end component.Even in this structure, also can not adjust the mutual alignment on two surfaces.
The EP0383479 patent specification has been described a kind of cover plate bar, and wherein a plurality of adjustment bolts provide the possibility of the distance between the lower limb of sliding area of free most advanced and sophisticated and front end component (slide-and-guide surface) of the card clothing that is adjusted at cover plate bar (supporting body plane).Yet described design only can not be set the mutual alignment on a plurality of surfaces along the vertical axis adjustment.In addition, this design has shortcoming, shown in the supporting body of cover plate bar must form by two parts, two parts of supporting body interconnect by described adjustment bolt more than two points along the whole width of carding machine.Thus, this adjustment work has produced bigger expense.
US 4,757, and 575 patent specifications disclose adjustable cover plate bar equally.Shown in the structure, the cover plate bar is made up of supporting body and two front end components.Connection between supporting body and the front end component is designed to be threaded.In this case, supporting body and front end component are in the assembling of the outside of carding machine.Because the gap between a plurality of parts of cover plate bar that manufacturing tolerance produces is compensated by space washer in assembling.The space washer of proper number is installed between supporting body and front end component, is positioned within the predetermined tolerance so the distance between the tip of the tip of cylinder card clothing and combing flat-clothing is also referred to as the combing gap.Shown structure makes and may re-use supporting body and front end component when changing card clothing.Yet this adjustable is confined to adjust the distance along cover plate bar vertical axis, and the additional correction of the mutual alignment on a plurality of planes is impossible.And the distance adjustment that will reach the tolerance order of magnitude and be 1/100mm needs too high cost, and for the correct space washer of selecting, needs to measure in advance tolerance to be compensated.
The possibility that the combing cover plate re-uses has been shown in the EP1004692 patent specification.Yet, the method of the distance between the free tip that is used to be adjusted at slide-and-guide surface or cylinder card clothing and combing flat-clothing described here needs machining cover plate bar working face, its shortcoming is, because the machining of slidingsurface, can increase as the distance between the free end of the lower limb of the sliding area of the front end component of slide-and-guide surface marking and the combing flat-clothing that indicates as so-called supporting body plane.Therefore, when changing card clothing, the cover plate bar must be classified arrangement according to its size before it can be re-used, to obtain the unanimity distance between the slide-and-guide surface of supporting body plane and all cover plate bars of carding machine.In many cases, even before using for the first time, the card clothing side of the cover plate bar that will come into operation of also will polishing, so all cover plate bars accurately have identical size.Has only the maximum requirement that just may satisfy carding property and quality in this way at present.
The connection of the known type that adopts between supporting body and front end component is that for example be threaded, cast connection (moulded resin), pressure connection (Pressverbindung), especially extruding connect (Quetschverbindung).So far all that use connect the principle that all is based on form fit (Formschl ü ssigkeit), for example embodiment of the interlocking moulding shown in the EP0303479.Adjust the cover plate bar in order not hinder, this connection type must manufacture has accurate cooperation.The shortcoming of this design is that the trade union that adds of closed tolerance causes expensive production method, and therefore brings expensive.
Summary of the invention
The object of the present invention is to provide a kind of cover plate bar or device of originally mentioning, its do not have above-mentioned shortcoming or with above-mentioned drawbacks limit among a small circle, thereby producing significant simplification aspect the production of cover plate bar and the adjustment, and bringing appreciable cost savings for the maintenance and operation of carding machine.And, the objective of the invention is to obtain in cover plate bar aggregate (Verband), to adjust the structure flexibly of each cover plate bar, obtain multiple possible adjustment simultaneously and select and adjust the improvement of accuracy, therefore under the situation that keeps equal in quality, obtain high as far as possible carding property.
This purpose is that the feature by independent claims 1,8 and 10 realizes.
For reaching this purpose, the present invention proposes the novel connection that between supporting body and front end component, realizes by novel connector.According to connection of the present invention, can obtain obviously simpler, the whole property of adjustable positions of cover plate bar more flexibly and more efficiently.The free end of cover plate bar card clothing forms a plane, is called the supporting body plane, and its downside that is basically parallel to supporting body extends.The lower limb of the sliding area of front end component forms the surface, is called the slide-and-guide surface, and this slide-and-guide surface can be designed to a plane, the situation that it extends in parallel in a plane corresponding to the edge of the sliding area of front end component.Yet the lower limb of the sliding area of front end component also can be adapted to the profile of the slidingsurface of bend, in this case, can obtain the surface similar substantially to the circumferential surface of cylinder.According to connection of the present invention, can determine position or the orientation of supporting body plane by adjusting connector and front end component with respect to the slide-and-guide surface, described position or orientation are adjusted corresponding with the qualification of clearance angle α.Clearance angle α is represented as the formed angle of vertical axis by the tangent line of the outer surface of cylinder and cover plate bar or supporting body plane, and wherein the vertical axis of this tangent line and cover plate bar intersects at the point of contact.Tangent line contacts in a bit with circumference on the point at point of contact being represented as.Clearance angle α can be a plus or minus.
Because according to novel connector of the present invention, the cover plate bar of possible is revolution combing cover plate assembly occupies the diverse location of the cylinder surface of facing, and for example conceivable is that the clearance angle α of continuous cover plate bar is periodically and increases (for example, 5,8,12,16,5,8,12,16,5,8 ... degree).
By novel connection according to the present invention, be possible in the adjustment that reaches on three axis.Therefore can be subdued mostly by the tolerance of making and assembling produces, thereby be formed the adjustment of obviously more accurate combing gap.If used according to connection of the present invention, can increase the tolerance commonly used in the cover plate bar is made now, make and assemble and brought considerable saving thereby give.Under the situation that does not have complicated and expensive adjustment and measuring method, on the drive manner that is adjusted at carding machine on a plurality of axis, produced new possibility.
Because it self is adjustable connecting, and neither needs for example space washer of extra parts, do not need to be used to adjust the parts of the different size of purpose yet, readjusting after card clothing is changed can be carried out in mode simple and that cost is calculated.The cover plate bar of replacing defective revolution combing cover board arrangement also is possible, and does not need to replace all cover plate bars or do not need the complete break-in of cover plate bar that will be used to replace to also in the size of the cover plate bar that uses.
According to the accurate adjustment of cover plate bar, the difference between each cover plate bar is very little, to such an extent as to do not need polishing before using for the first time.Under any circumstance, the cover plate bar that is loaded into is polished under new state in advance, makes and assemble the difference that produces so it may be eliminated.Because according to the new adjustable property of connection of the present invention, so this polishing has in advance just no longer needed.
Connection according to the present invention is characterised in that front end component is not directly to be fixed to supporting body, but is fixed to supporting body by connector, and therefore removable or adjust at least one axis, and with the orientation and the location independent of connector.Being connected by clamping to connect of front end component and supporting body guaranteed.For the reinforcement clamp stressed joint, it is coated like this clamp to connect the surface that is in contact with one another, even under low tensile force effect, can generation part yet skid.Even in order also to have the adjustment of reliable combing cover forward end position under low tensile force effect, this surface can correspondingly be applied by part parts coated or only clamping connection.When the combing cover forward end had bigger load, the coating with the effect that increases stiction also helped clamping connection stability.
Layout that the present invention is favourable and embodiment can find in the dependent claims.

The specific embodiment
Schematically show the side view of existing revolving flats carding machine 1 among Fig. 1.The fibrous material for the treatment of combing can comprise the mixture of natural fabric or synthetic fiber or these fibers, and it is received by licker-in 3 as lap then, and be sent to cylinder 4 to be fed into feed well 2 by shredding and form fibre bundle that be cleaned.Fibre bundle is by shredding and parallel being placed on the cylinder.This operation is carried out mainly due to the co-operating of cylinder and cover plate strip device.Revolution combing cover plate drives by the opposite direction of guide roller 6,7,8,9 along the direction of rotation 10 of cylinder 4.
Fiber forms fiber web, and this fiber web is positioned on the cylinder 4, and the roller 11 that doffed then removes, and forms card sliver 13 at the deferent segment of being made up of a plurality of rollers 12 in a manner known way.This card sliver 13 by ribbon storeroom 14 cycloid formulas be deposited in the transport tube 15.
Fig. 2 enlargedly and illustrate in greater detail carding machine 1 in the Fig. 1 in the zone of revolution combing cover plate 16.For convenience of description, only show single cover plate bar 16, all cover plate bars all comprise a supporting body 17 and two front end components 18, this supporting body 17 is designed to hollow profile and supports combing flat-clothing 19, front end component 18 be installed to the hollow profile style supporting body 17 each end and be connected to supporting body 17 by connector 27.
Revolution combing cover plate 16 drives by the conveyer belt 5 that for example is designed to cog belt, and this revolution combing cover plate 16 is opposite mobile continuously with the direction of rotation 10 of cylinder 4.And be understandable that cover plate bar 16 on-stream being arranged to are evenly distributed on the whole length of conveyer belt 5.In the zone of cylinder 4, cover plate bar 16 is carried by this way, and it is extruded on two so-called bends 22, and bend 22 is installed on the carding machine backplate 1a.In this case, the slide 26 that is installed on the front end component 18 contacts with the lower limb of front end component 18, and the lower limb of front end component 18 is called as the slide-and-guide surface 20 of bend 22, towards the upper side 21 of this slide.Bend 22 is provided with on its radial height like this, thereby and the distance of slide-and-guide surface 20 from supporting body plane 25 of front end component 18 form so-called combing gap 24 together, this combing gap 24 has the predetermined value relevant with the pre-adjustment of cover plate bar 16.And slider bar also can be positioned on the bend 22.If suitably design slider bar, just can be on front end component 18 without slide 26.Combing gap 24 is the distance between the free tip on the tip of cylinder card clothing 23 and combing flat-clothing or supporting body plane 25.The size in combing gap 24 is carding property to combing processing especially and is had significant effects at carding machine 1 place by the fibroreticulate quality of combing.Being provided with equally of so-called clearance angle α has significant effects to carding effect.
Fig. 3 a shows the detailed view of an end of cover plate bar 16 in the mode of perspective view.Can be clear that from this figure cover plate bar 16 is made up of the supporting body 17 that is designed to hollow profile, connector 27 and front end component 18 basically.Show the slide of pushing open 26 on the front end component 18, the lower limb of this slide 26 has formed the slide-and-guide surface 20 of cover plate bar 16.If slide 26 is because the suitable design of front end component 18 is removed, the lower limb of front end component 18 just forms the slide-and-guide surface of cover plate bar 16.Opening portion 18a on the front end component 18 forms the fixedly zone of conveyer belt 5 (not shown).Structure setting shown in front end component 18 can be pressed, but it also can comprise two pins, described two pins are located at left side and the right side of opening portion 18a, thus the slide 26 shown in replacing.In this case, the slide-and-guide surface 20 of cover plate bar 16 can be formed by the lower limb of pin.Can also use the band shape director element of the embedding of describing among the DE 3907396 to replace slide 26, in this case, the upside of pin is installed to and is suitable on the director element cover plate bar 16 is fixed on the part of conveyer belt 5.Fig. 3 a also shows connecting according to clamping of the present invention by connector 27 between supporting body 17 and the front end component 18.Connector 27 is pushed into the bottom of the supporting body 17 of being arranged to hollow profile.
By connector 27 (see figure 3)s that preferably are set to clamp connection according to the present invention, front end component 18 can be regulated with respect to supporting body 17 along at least one axis.On the one hand, front end component 18 can move along vertical axis Z with connector 27, shown in direction arrow A.This makes combing gap 24 to change, for example only be preferably between 0 to 1mm 0.05 and 0.7mm between change.In addition, front end component 18 and connector 27 together can be around rotating with the corresponding X-axis of the transverse axis of supporting body 17 or cover plate bar 16, can regulate slide-and-guide surface 20 by this C that rotatablely moves, the C that rotatablely moves around X-axis is used to regulate slide-and-guide surface 20, thereby the even contact between the slidingsurface 21 of acquisition slide-and-guide surface 20 and bend 22, even contact that is obtained and possible mismachining tolerance are irrelevant.Because the hollow profile of supporting body 17 is in the position that a position is higher than connector 27 self that pushes of connector 27, so be possible around the rotation C of X-axis.Supporting body plane 25 can reach 10 ° with respect to the slide-and-guide of front end component 18 surface 20 around the B that rotatablely moves with the corresponding Y-axis of the longitudinal axis of supporting body 17 or cover plate bar 16, be preferably and reach 6 °, in this case, front end component 18 is not only with respect to supporting body 17 rotations, and with respect to connector 27 rotation, thereby obtained the free degree of remarkable increase.This can realize, because front end component 18 for example tightens to connector 27 by screw thread, therefore the rotation around Y-axis is possible.The intersection that is formed by supporting body 17 and front end component 18 is represented by angle α thus, is called clearance angle (seeing Fig. 4 c).By appropriate structuring connector 27, the numerical value of above-mentioned gap width and rotation can enlarge arbitrarily or also can dwindle as required.What also can expect is, suitable setting by supporting body 17, front end component 18 and connector 27, the fixing clearance angle α (seeing above) that predesignates also can be set, and for example the form by draw-in groove (Rast) or groove can form the interlocking between connector 27, supporting body 17 and the front end component 18.
For the sake of clarity, Fig. 3 b shows two reference planes, supporting body plane 25 and slide-and-guide surface 20 and affiliated axis X, Y and Z thereof along the bottom view I among Fig. 3 a.Arrow A, B and C show front end component 18 separately or the possible direction of motion of adjusting with respect to supporting body 17 with connector 27.

Fig. 4 b show front end component 18 with connector 27 at the opening portion of supporting body 17 with interior rotation around X-axis.The angle that forms between the obliquity of the trunnion axis Y of supporting body 17 and connector 27 and front end component 18 under this situation is represented with β.Fig. 4 c shows the view III among Fig. 4 a.Fig. 4 c shows front end component 18 rotatablely moving around Y-axis.The angle that forms between the obliquity of the vertical axis Z of supporting body 17 and front end component 18 under this situation is represented with α.With above-mentioned reverse movement, in the rotation of Y-axis, have only front end component 18 self to rotate at front end component 18, connector 27 remains on vertical substantially position.In the rotary course of Y-axis, front end component 18 is with respect to supporting body 17 and connector 27 rotations at front end component 18.
Fig. 5 a shows the different embodiment that are provided with at the combing cover plate assembly that turns round the combing flat caiding machine capable with 5b.
In Fig. 5 a, cover plate bar 16 is arranged like this, looks along the direction of rotation 10 of cylinder 4, crosses three cover plate bars and has obtained the combing gap 24 that reduces gradually from cover plate bar 16 to cover plate bar 16.After three cover plate bars 16, same period is restarted (periodically).
In Fig. 5 b, cover plate bar 16 is arranged like this, looks along the direction of rotation 10 of cylinder 4, crosses three cover plate bars clearance angle α that 16 acquisitions reduce gradually from cover plate bar 16 to the cover plate bar.After three cover plate bars 16, same period is restarted (periodically).
Because the adjustable according to the connection between supporting body 17 of the present invention and the front end component 18 provides can obtain the distortion of countless arrangements.
Fig. 6 a shows the side view of cover plate bar 16, and this cover plate bar 16 has the connector 27 of one and superincumbent front end component 18 is installed.This view is from input side, that is to say on-streamly, and cover plate bar 16 moves and escape to cylinder surface 28 from the observer towards the observer.Combing gap 24 (schematically showing) determined by the distance between cylinder surface 28 and the slide-and-guide surface 20 and distance h 2, and the preset distance between the slide-and-guide surface 20 of distance h 2 and supporting body plane 25 and input side is corresponding.By clearance angle α can select any needs between h1 and h2 ratio is set, its result makes for each cover plate bar 16, and the combing gap 24 of input side does not need identical with outlet side.
Fig. 6 b shows the cross section according to connection of the present invention.Comprise intermediate member 27b, at least one edge member 27a, 27c and tension part 27d as the connector shown in the exemplary embodiment 27 preferred the clamping in the syndeton.Clamp connection 27 activates by tension part 27d, and as shown in exemplary embodiment, the activation of clamp connection 27 can realize by the bolt as tension part 27d, preferred expansion bolt.Yet except bolt, the tension part 27d of use can be that other power is introduced parts, for example spring, key (Keil), tensioning fastener etc.Intermediate member 27b by tension part 27d by this way forward end parts 18 move, edge member 27a, 27c are outwards moved with respect to supporting body 17.This connects in the clamping that generation power between intermediate member 27b and edge member 27a, the 27c and between edge member 27a, 27c and supporting body 17 cooperates, and this clampings connects connector 27 and and then front end component 18 remained on the position of selection in advance of the different axis X in supporting body 17 upper edges, Y, Z.The optimal way of intermediate member 27b and edge member 27a, 27c has been shown among Fig. 6.Yet other version of the different parts of connector 27 also is possible with conceivable, for example cylindrical or conical.The true form of employed parts also depends on the design of supporting body 17 and will adapt with the moulding of supporting body 17.Supporting body 17 and clamp connection 27 are coordinated in their configuration design mutually, thereby set up enough big adhesive force (Kraftschluss) front end component 18 are connected to supporting body 17, preferably can not cause the distortion of supporting body 17 in this case.According to the selection of tension part 27d, can load onto fixed part in addition, this fixed part can be implemented in known manner according to tightening technology, for example the fixed part of stop washer, wire type or adhesive.
Fig. 6 c, 6d show other the possible version that is connected according to of the present invention with 6e.
In Fig. 6 c, activate connection by knocking on intermediate member 27b.In this structure, do not use tension part 27d.
In Fig. 6 d, because the activation of tension part 27d, intermediate member 27b is out of shape by this way, thereby there is no need to use special- purpose edge member 27a, 27c in connection according to the present invention.In this application scenarios, supporting body 17 is considered to edge member 27a, 27c around the zone of intermediate member 27b.
