Definitions
- the invention relates to an endless belt according to the preamble from claim 1 and a revolving lid assembly according to Claim 10.
- An endless belt or a revolving cover assembly this type is shown in EP-A-627507.
- the belt according to EP-A-627507 includes pairs Connecting elements, each element being one with the elongated Belt strap made of a single piece and has a foot part removed from the belt band, and wherein each foot part as a holder for one provided on the flat bar Counterpart can serve.
- each foot part as a holder for one provided on the flat bar Counterpart can serve.
- each pair of elements opposite the counterparts of the flat bar a snap connection.
- the flat bar of a revolving flat card comprises a clothing receiving part, which is connected to the drive belt must become.
- the flat bar can include end heads that both with the clothing receiving part as well as with the drive belt are to be connected.
- the invention is applicable in any case with a flat bar, of which the receiving part is shaped as a hollow profile and with separately formed end heads connected to the hollow profile is provided.
- a flat bar is for example in US-A-4827573 and consists of one steel tube drawn through a profile shape. At both ends of the flat bar are massive head pieces for fastening provided with a drive belt. These headers are either by welding or by riveting or screwing connected to the flat rod so that they can be replaced can, if they have become unusable due to wear.
- a preferred solution to the latter problem is in EP-A-627507 (Figs. 8 to 11) and is also related to of the present invention.
- this is Connection type particularly advantageous when light metals, such as Aluminum or the like, as a hollow profile for the manufacture of flat bars can be used.
- Fig. 1 is a known known revolving card, 1, for example the applicant's C50 card, shown schematically.
- the fiber material is in the form of dissolved and cleaned flakes fed into the filling shaft 2, from a breeze (or lickerin) 3 as a cotton swatch, handed over to a drum (or drum) 4 and by one Moving cover set 5 parallelized, the over pulleys 6 counter to or in the same direction as the direction of rotation of the drum 4 is driven. Fibers from the one on the drum 4 Nonwoven fabrics are then removed from a take-off roller 7 and in an outlet section consisting of different rollers 8 formed into a card sliver 9. This card sliver 9 is then transferred from a belt deposit 100 into a transport can 110 filed in a cycloidal manner.
- the flexible sheet 120 is one in a section such a card is shown, with flat bars running around it 13, (only two shown) by a toothed belt 14 and a drive not shown here in sync or slowly moved in the opposite direction to the direction of rotation of the drum 4 become.
- Adjustment elements 15 are on this flexible bend 120 provided with which the distance of the flat bars 13 to Drum surface, the so-called carding distance, set can be.
- the constructive execution of such control elements on the flexible arch is, for example, from the German utility model DE-U-9313633 known to the applicant.
- the adjusting elements 15 are not merely manual adjustable, but they are by means of an actuator system, for example small servomotors 17, automatically adjustable. details of this system are listed in EP-A-787841 and are not repeated here.
- the revolving cover set of a card according to DE-A-3835776 comprises for example 106 flat bars, of which 41 are in the working position, that means being in contact with the sliding guide.
- Fig. 3 shows the preferred embodiment according to EP-A-627507 for connecting flat bars with a drive (toothed) belt.
- a head piece 36 of a flat bar 31 comprises an insertion part 41 and a sliding part 50.
- the part 41 extends into the receiving part of a hollow profile and is fixed in it.
- the attachment is based on FIGS. 8 to 11 of EP-A-627507 have been explained, and it is referred to here the declaration is not repeated.
- the sliding part is in the working position of the flat bar the flexible sheet 120 and when returning on a rail (not shown) along.
- the sliding section 50 is with provided two attachments 52, and form the two attachments 52 together a receiving opening 54.
- the drive belt 14 is formed as a toothed belt.
- the teeth on the "inner surface” 56 of the belt i.e. on surface 56, those related to the circumferential closed path inside working with drive wheels (not shown) together.
- the flexible sheet 120 in the working position of the flat bars opposite, recesses 60 are provided in pairs, the recesses 60 each receiving an attachment 52.
- a protrusion 10A formed integrally with the belt is between the recesses 60 of each pair have the belt 14 a protrusion 10A formed integrally with the belt is.
- the protrusion 10A is in the receiving opening 54 added between the resolutions 52.
- the lead points a slot 11, whereby two "legs" are formed, each of which is provided with a cam 12 in the foot area is.
- the attachments 52 each have an inclined surface 62 in order to to be able to better accommodate and hold the cams 12.
- the legs are elastically compressible to a snap connection to form with the head part 36 of the flat bar 31.
- connection between the projection 10A and the headers 52 arises, on the one hand is firm enough to hold the flat bar to keep on the strap (even if it is no longer through the arch 120) and the driving forces transmitted, on the other hand, the connection is also through a Operator can be released (manually) without special tools. Since no additional (loose) elements are necessary, can manufacturing costs kept low and assembly / disassembly be carried out efficiently.
- the material pairing Slide section of the flat bar / slide guide of the sheet can be optimally adjusted, and the manufacture of the clothing receiving Bands from the flat bar can still be used if possible be done inexpensively, with strength and weight this body can be optimally chosen.
- the flat bar 31 with that shown in Fig. 3 Profile shape is drawn when using a steel tube, however, if aluminum is used, by a suitable one Profile shape pressed through (so-called extrusion).
- the flat bars are used for the metals steel and aluminum manufactured by so-called cold forming.
- the head 36 is preferably made of cast iron or sintered metal, can, however, also be made from another stable metal his. It should be noted that the bottom of the headboard should be hard enough to be unnecessary and to prevent rapid wear and tear.
- Fig. 4 shows a first embodiment of an endless belt according to the present invention, wherein only a minor distance of a elongated structure is shown in the figure.
- the illustrated Structures are in the longitudinal direction of the belt always repeated, so that the description of the pictured Part is enough to explain the whole.
- the strap is as Whole indicated by the reference numeral 200, and it includes a belt 202 continuous in the longitudinal direction, beam pairs 204 or 206 of connecting elements 208 or 210 and teeth 212.
- the strap is cast in one piece, with the Reinforcements extending in the longitudinal direction (e.g. filaments or Wires, not shown) can be cast.
- the (matrix) material is preferably an elastomer, e.g. Polyurethane.
- the band 202 has a predetermined width B (e.g. in the area 20 mm to 30 mm) and a predetermined thickness D (e.g. in the area 1 to 3 mm).
- the thickness D can depend on the tensile forces to be transmitted, e.g. dependent on on the number of flat bars.
- the length of the strap 202 is explained in more detail below.
- Each connecting element 208 or 210 consists of a crossbar, which extends over the entire width B of the band 202, namely perpendicular to the longitudinal direction of the belt.
- everyone Beams 208 and 210 have a predetermined height H (e.g. in the range 3 to 8 mm).
- the bar 208 or 210 is wedge-shaped in cross-section, the smaller "root" from the wedge connects to band 202 and the larger head part from Band 202 is removed.
- the bars 208, 210 of a pair (e.g. of the pair 204, which is also shown in Fig.
- Each bar therefore has an inclined surface 214 and 216, and the sloping faces of a pair are in opposite Longitudinal directions.
- each sloping face of a pair e.g. pair 204, Fig. 4
- an inclined surface of the adjacent pair e.g. the pair 206 opposite.
- the sloping surface 214 or 216 of a bar closes with the adjoining surface 220 of the tape 202 a predetermined angle ⁇ (e.g. in the range 60 to 80 Degrees) with the band 202 extended.
- each bar 208 and 210 is at least in Root area rubber-elastic, so that the beams by means of suitable Forces on the inclined surfaces (or in the head area general) can be pushed against each other to their mutual Reduce distance in the head area.
- each pair of bars 204, 206 is moved from right to left in Figures 4 and 5.
- Each pair of bars is preferably designed symmetrically, so that it doesn't really matter which way it goes is moved.
- the assumption of a certain direction is simplified but the descriptions below.
- In the "ready state" (Volume 202 stretched out straight, without Use of force on the bars 208,210) is the distance in the longitudinal direction of the band 202 between the previous one free edge K1 of the pair of bars 204 (FIG. 5) and the trailing one free edge K2 of the same pair a predetermined Value "L", which ranges from 12 to 25 mm. can lie.
- the distance "L” subsequently becomes the "span” of the pair of bars called.
- the corresponding distance "1" at the root the bar 208, 210 is one in the same state smaller predetermined value, which is in the range 9 to 22 mm. can lie.
- a flat bar that is supposed to work with this strap is indicated by reference numeral 222 in Fig. 6, and he comprises a hollow profile 224 and two end heads 226, only one of which one is visible in FIG. 6 or FIG. 7. Every end head 226 has a connecting part (not visible in these figures, but see the insertion part 41 in Fig. 3), which in each End part of profile 224 pressed in and held therein is.
- the preferred solution for attaching the end heads 226 in profile 224 has been described in EP-A-627507, another attachment, which the without much effort Requirements met, could be used.
- the insert part the end head is therefore not further described here.
- a slide shoe / clip part protrudes at each end of the profile 228 (FIG. 7) of the respective end head 226 from the end of the profile.
- the part 228 comprises two strips 230 (FIG. 6), which are in extend in the longitudinal direction of the rod 222. These ledges 230 each form a sliding surface 232, which on the sliding surface of the flexible sheet slides when the rod 222 is in the working position is.
- the strips 230 are made of one piece with cross struts 234 formed, which together with the last one Inclusion of the specified size for the corresponding elements of the belt 200.
- the size of this opening in the The longitudinal direction of the strips 230 preferably corresponds to that Belt width (or bar length) B (see Fig. 7 and Fig. 4). This ensures that the straps of the revolving cover assembly and the flat bars of the unit are on the side center each other.
- the bracket or connection function is made up of two strip parts 236 (Fig. 6), which is also wedge-shaped in cross section are so that they each have an inclined surface 238 or 240 exhibit. These inclined surfaces 238, 240 face each other, and they have a predetermined minimum distance Mn (Fig. 7), which is significantly smaller than that Span L (Fig. 5) of a pair of bars in the aforementioned standby state.
- the inclined surfaces have a predetermined one Maximum distance Mx (Fig. 7), which is explained in more detail below becomes.
- the distances Mn and Mx are as below denotes the "opening widths" of the bracket part.
- each wedge-shaped part the ledge 230 is approximately equal to the height H of the beams 208,210, but the total height LH (Fig. 6) of each ledge is 230 significantly larger, so that the sliding surfaces 232 (in the arrangement 8) lie far above the bars 208, 210.
- Each flat bar 222 is in the same way with connected to a pair of bars.
- the distance between neighboring ones Flat bars 222 are predetermined and should be as possible be kept small, it is in Fig. 8 with the reference numerals "t" indicated.
- the distance t is of course through the construction of the strips 230 and the distance between adjacent ones Given pairs of bars. The latter distance is too specified and amounts to 208.210 (at the roots of the bars the area 220 of the band 202) the value "S" (Fig. 8), which in the Range 14 to 27 mm. lies.
- the width Mn of the entrance opening of the clip is preferred about the same size as the dimension "l" (Fig. 5) on the Root of the bars 208, 210.
- the maximum width Mx of the bracket but is preferably less than the span L des Pair of beams. In the assembled state (Fig. 8) is therefore the Distance A of the bars in the head area is somewhat reduced, i.e. the Bars 230 urge the bars 208, 210 against each other also in fully snapped condition. Mutual is much more Squeezing the bars 208, 210 together when snapping the clamp is necessary, as follows with reference to FIGS. 10 until 12 is explained.
- FIG. 9 The holding forces are also determined by the "degree of bending" of the Belt band influences, as explained for the time being with reference to FIG. 9 becomes.
- Figures 4, 5 and 8 all show (for simplicity) the belt band 200 in the straight state. But the hiking cover path is nowhere, and he includes two sections on the deflection rollers in the end areas, that require a significant bend in the belt.
- the outer surface of the band 202, with the beams 208,210, is formed convex.
- the effect of this bend in the absence of a bracket is shown in FIG. 9 - the bars 208, 210 of each pair are particular pulled apart in the head area so that the distance A (Fig. 5) increases to A + (Fig. 9).
- the snap connection according to the invention must also do this Freeing of a flat bar (e.g. while waiting for the flat bars or to check a flat rod) and the (re) attachment enable a staff - and if possible with the (still) running revolving lid aggregate.
- Attaching one The rod is shown schematically in FIG. 10. It will be for the time being one of the inclined surfaces of the bracket (shown in Example the surface 238) in contact with the inclined surface (214 in Fig. 10) of the corresponding bar (208 in Fig. 10) brought.
- the flat bar 222 is inclined such that the edge Ki in contact with the other bar of the clip can be brought with the head of the other bar 210 (State according to Fig. 10).
- edge Ki moves past edge K2 (FIG. 5) can what the clip snaps mean.
- the simple beam head shape according to FIGS. 4, 8 and 10 comprises one End face lying in a single plane. If those Form is chosen is both with problems when "impressing" as well as damage to the edges K1 and K2 expected. A partial solution to this problem is with dashed lines Lines indicated in Fig. 5, where the end face is chamfered to form baffles 242, 244. Opposite the fully extended variant reduces the span of the Pair of bars on L1. The transition between a guiding surface and the corresponding inclined surface of the beam is preferred more rounded than edged. This construction measure simplifies the impression according to Fig. 10. The attachment and even loosening a flat rod could still may be a bit tedious for an operator.
- the span L or L1 is reduced accordingly, which makes it easier to impress. It is now the case that a minimal bend of this kind occurs comes when a flat bar 222 on the sliding surface of the flexible sheet 120 (Fig. 12) is placed.
- the corresponding easing the holding force is low on the one hand and takes place on the other hand in a place that is suitable for attaching or losing weight is unsuitable.
- the latter functions should be on return path 248 are exercised.
- strap 202 but preferably supported by a return rail 246, which is even a slight curvature in the "wrong" direction can have. It should therefore be in at least one place (e.g. 250, Fig. 12) there is no guide for the belt so that an operator can get the desired one here Bend the belt yourself (with or without tools) can.
- This "assembly point" is preferably in the area where a belt part moves in the hiking trail leaves along a deflecting roller and the return rail has not yet reached. The assembly point can be sent to one other location along the return path, or it can even spread some assembly points along the path become. It is important that the assembly points for the the two straps of a revolving cover aggregate correspond.
- the inclined surface 238 comes or 240 of each strip 230 in full contact with the inclined surface 214 or 216 on the corresponding bar 208 or 210.
- FIG. 13 shows a modification of the arrangement according to FIG. 12, after which the return rail 246 is provided with a recess 252 and this recess 252 is a securing plate 254 is assigned.
- a pair of bars e.g. 207 now joins incorrectly installed flat rod with the sliding head 228 of the locking plate 254 approaches, the locking plate 254 presses the clamp part of the sliding head 228 down over the pair of bars.
- the locking plate 254 is rotatable carried about an axis 253 and by an elastic means (e.g. spring 256) biased towards recess 252.
- the locking plate normally holds a predetermined one Distance from the return rail, e.g. because of a not shown stop. When snapping a clip part the locking plate is up (against the preload) pushed away from the return rail 246.
- the rail 246 itself is rotatably supported by an axis 257 and by means of an elastic means 258 (e.g. a spring) Pretensioned up to tension the belt 200.
- the belt is therefore normally not in the recess 252 deflected, but the recess is bridged by the belt.
- a redirection into the recess takes place under Pressure from the backup plate 254 when the latter is up is pushed, as already described. The redirection has that Effect described in connection with Fig. 11.
- both return rails (one on each machine side) be provided with a device to the Elements of the snap connection engage with each other bring.
- the device has a recess and locking plate 13 includes the two devices snap in the elements at the same time.
- the invention is not restricted to the embodiment shown. It would be e.g. possible the inclined surfaces of the beams to face each other directly and with the flat rod to provide a "snap lock", the two inclined surfaces has and pushes the bars apart when attaching the rod. Such a variant would not be equally good in able to withstand torques when carding out the set can arise and tend to the truss rod to tilt its own longitudinal axis.
- Monitoring means can be provided to monitor the deployed Cover and their connections and check one To issue an alarm if errors are discovered.
- Each crossbar can be formed from a plurality of partial bars what each part is only a part of Belt width extends.
- FIG. 14 shows laterally parts of a flat bar 222, which correspondingly between two belts 200A, 200B, on opposite sides of the card (not shown in FIG. 14, cf. Fig. 1) is performed.
- the central part of the flat rod has broken through.
- the flat bar 222 is shown viewed from above on its "return path", ie the flat set C moves upwards for cleaning, so that the profiles 31 (FIG. 3) are not visible, but the sliding shoes 228 of the end heads can be seen.
- Each of the sliding shoes is attached to a pair of bars 205A, 205B on its belt accordingly.
- the pairs of bars lying on the belt 200A adjacent to the pair of bars 205A, designated 204, 206, are not provided with flat bars.
- the flat bar 222 can be, for example, the first lid that is placed on the belt during assembly or subsequent maintenance.
- the belt is again 200 provided, and comprises a band portion 200 with teeth 212.
- Der Band portion normally includes extending in the longitudinal direction Support elements, which are shown with reference number 260 are shown.
- a pair of bars 262, 264 is in Side view shown, with only bar 264 shown as a whole is.
- the pair of bars 262, 264 are through one Slot 266, which extends from the outer (free) end of the Beam extends up to the belt portion 202 of the belt, separately.
- the side of the bar opposite bar 262 264 is formed by a guide surface 268 on the outside End of the beam, an inclined support surface 270, which the Surface 216 is similar to FIG. 4, and an oblique foot portion 272.
- the sloping foot part 272 is with the sloping holding surface 270 connected via a joint 274.
- the bar 264 bends around it Hinge 274 instead of around a root, as in the case of the beams 208, 210 (Fig. 4).
- It also forms the holding surface 270 with the belt length in a straight position, as in 15, an angle ⁇ (in the range 60 to 80 degrees). In this case the "length" of the belt with reinforcing elements 260 shown.
- Fig. 15 shows edges where two surfaces meet each other. This is not the actually desired shape for reasons that already exist have been broadly stated. Such edges are preferred rounded off, especially if there is a risk that the Cut bars on the clamping or fixed elements becomes.
- Rounding off beam surfaces can, for example, shape as shown by reference number 278 in FIG. 16, where the holding surface 278 is rounded. But it will to be relatively difficult to have a good cooperation between the Slide shoe and the bar in the latter embodiment to reach, partly for the reason that it's relative Heavy is the areas on the sliding shoes for the rounded To determine the bar exactly.
- each bar can have a "cut from below" profile as in Figs. 4, 5, 15 and 16 shown, must be provided (i.e. the bar surfaces that lie against the cover have fewer Distance from each other in a position near the Belt body than in a farther from the belt Position) so that a snap connection is formed between the bars and the cover elements.
- the beams themselves are not elastic are deformable.
- a "pair" of bars can be multiple Contain elements, at least two of these have to tend to move away from or approach each other, when the belt body is bent.
