Definitions

  • the present invention relates to a flat end head of a flat bar for a Revolving cover of a card or card.
  • a large number of flat bars are used in generic cards or cards guided over the card drum on a sliding guide.
  • This arrangement is called also revolving cover. They are by an endless element, for example a belt or a chain, connected and are moved by a drive element.
  • Both the Flat bars as well as the drum have a set, for example fine needles or in the form of a saw tooth, which interact with each other for cleaning and the parallelization of the fibers are decisive.
  • the Carding gap between the two sets is at most a few Tenth of a millimeter.
  • the flat bars each have a flat end head at their ends.
  • the Lid end head has an attachment area for attachment to the end of the Flat bars and at least one sliding surface.
  • the lid end head also has another device to fix the endless element, for example one Recess.
  • An example of such a combination of flat rod, endless element, and the lid end head can be found in the patent EP0 627 507 B1.
  • the sliding surfaces of the lid end heads are also the surfaces, making the whole Flat rod rests on the slide guides. You still have the task of To interact with the sliding guide and for a low-friction and dimensionally accurate run of the flat bar. It is therefore important that the end cap and the Sliding guide are precisely matched to each other, so that the distance between Flat rod and drum (each of the clothing tips) in a predetermined Tolerance range can be kept.
  • the Slideway and / or the sliding surface of the lid end head wear. in the essential is the wear of the sliding guide or the sliding surface of the Lid end heads a question of the material pairing used.
  • the wear can also be reduced or minimized through the use of lubrication systems (e.g. Oil lubrication).
  • the sliding guide on the card is traditionally made of cast iron.
  • the newer state the technology discloses sliding guides with sliding strips made of polymer material, for example EP 620 296 or EP 361 219. The latter does not disclose which Material for the lid end head is needed.
  • EP 620 296 discloses for Cast iron or sturdy metal end caps. In addition to these materials also solid steel (US 4,827,573) or an aluminum / aluminum alloy (US 4,300,266) for the manufacture of the lid end heads. In these However, patents do not provide any information about the material for the sliding guide made.
  • sliding shoes can be found in US Pat. No. 4,300,266, the Material for the slide shoe phosphor / bronze or a polymer material, for Example MoS2 / nylon or a combination that contains PTFE.
  • Patent DE 198 34 893 publishes a polymer material sliding shoe Polyamide.
  • the current flat bars are made of steel or cast iron and partly equipped with sliding shoes. Although these Combination meets the requirements of the flat bars, this is to be made disadvantageous. Depending on the type, around 100 flat bars are used on one machine. Each additional component on a complete flat rod increases the Production expenses.
  • the object of the invention is to optimize the end cap under Consideration of the material pairing and the problem described above.
  • a solution according to the invention provides that the entire end of the lid is made from one To produce pieces from a polymer material.
  • a lid end head consists of several areas: the first area is responsible for fastening with the flat bar, the second area consists of the actual one Head that rests on the sliding guide and additional corresponding sliding surfaces adduced. One of these areas could also have a device for the Have attachment of the endless element.
  • Another solution according to the invention provides fiber reinforcement of the Polymer material before. This can increase the strength of the end cap.
  • the approach between the attachment area and the actual head is during the operation of the revolving cover exposed to several forces.
  • the flat bar will only carried by its lid end heads. In order to ensure an exact measurement these end caps must not bend. In addition, they are, through the side Movement of the flat bars through the drive element, also torsional forces exposed. A twisting of the material would also negatively affect the dimensioning influence.
  • the entire lid end head is made of one material is manufactured that wears out.
  • the selected fiber material can then be sent to the Surface of the sliding surface.
  • Abrasive fibers could then be an undesirable one Cause the sliding guide to rub.
  • Carbon fibers for example PAN fibers®
  • aramid fibers polyamideimide fibers, for example Kevlar®
  • a mixture of the two fibers could also be used. Especially since that Aramid fibers show a favorable wear behavior compared to the sliding partner and the carbon fibers achieve better strength. Combining results in an optimal solution.
  • An additional solution according to the invention is a lid end head made of a Polymer material with solid lubricant additive. Trials have shown that not everyone Combination of a base polymer material and solid lubricant on cast iron shows optimal lubricity and lubrication properties. preferred Combinations are shown in Table 1, column 1 are again the preferred ones Groups of base polymer materials listed and the preferred in column 2 Solid lubricants that are used for the task of the end cap as the most appropriate show.
  • Solid lubricants In order to obtain the desired sliding properties, 1-15% by weight of solid lubricants are required, preferably 5-12% by weight, very preferably 8-11% by weight. In the case of molybdenum disulfide (MoS2) and polysiloxane, a smaller amount of solid lubricants is sufficient, for these 2 solid lubricants 1-6% by weight, preferably 1-3% by weight, for example 2% by weight, are preferred.
  • Preferred combinations of base polymer material and solid lubricant Based on polymer material lubricant a. PTFE (fiber or powder) I. Polyamide PA b. Polysiloxane (silicone) c. graphite d. polyethylene e. Molybdenum disulfide (MoS2) II.
  • Polyoxymethylene POM a. Polysiloxane (silicone) b. PTFE (fiber or powder) III. terephthalate a. PTFE (powder or fiber) IV. Polyetheretherketone PEEK a. PTFE (powder or fiber) a. PTFE (powder or fiber) V. Polyimide PI b. graphite c. MoS2
  • the lid end heads can be manufactured using an injection molding process.
  • FIG 1 shows how the flat end head with the flat bar and the sliding guide on one Teasel works together.
  • the flat rod is formed by a hollow profile, part of which is used as a holder for the lid end head.
  • the end cap (1) is inserted into the flat rod (8) pushed in as far as it will go.
  • the lid end head lies together Flat rod on the slide guide (6), (In Figure 2, this is from the side of the Drums shown. It can be clearly seen that the sliding guide is in the form of an arc follows the curvature of the drum.)
  • the carding gap (12) is the distance between the Set (11) of the flat bar and the set (10) of the drum (9). This should be true to size.
  • FIGS 3 and 4 show the lid end head in detail.
  • a lid end head consists of several areas: the first area is responsible for the attachment with the Flat rod (1), the second area consists of the actual head (5) on the The sliding guide rests and additionally has corresponding sliding surfaces (2).
  • One of Both areas could also have an additional option for the Attachment of the endless element, for example a recess (3) in the actual Head.
  • Figures 5 and 6 show the same end caps as in Figures 3 and 4.
  • the Sliding surface has at least one, advantageously a plurality of cleaning grooves (4)
  • the purpose of these cleaning grooves is to remove impurities that are on the Have reached the sliding surface, to be removed or collected or removed.
  • the Cleaning grooves are dimensioned so that they are sufficiently dirty can absorb until they are brushed out when cleaning the lid.
  • the cleaning grooves also have a sufficient depth, which means that Grains of sand or other dirt no further contact with the Counter surface, i.e. the sliding guide. This is a removal of the Contamination without damaging or scratching the sliding guide or the Sliding surface of the lid end head possible. This creates an even surface ensures the sliding guide and thus a uniform abrasion of the sliding surface.
  • one can hold the lid head firmly in the flat rod Profile (17) are attached to the fastening part of the lid end head, for example on at least one long side, raised longitudinal stripes (see FIG. 4 and 5, (17)).
  • This profile has the task of inaccuracies in the hollow profile of the Lift the flat bar by counter pressure and increases the clamping of the Lid end head in the flat bar.
  • At least one stop block is required. Disassembly takes place in that the cylinder (13) moves away from the flat rod in the longitudinal direction, the holder (14) holding the flat end head and pulling it out of the hollow profile. In order to ensure that the flat rod is not pulled along, a stop block (15) blocks the way. Assembly takes place in that the cylinder or piston (13), with the new end cap held by the holder, moves in the direction of the flat rod and thereby pushes the end cap into the hollow profile of the flat rod as far as it will go. In this case, the stop block (16) prevents the flat rod from being pushed away. Rounding of the edges and bevels of the lid end head according to the invention can simplify this process.
