Definitions

  • the invention relates to a chain for tenter frame dryers according to the preamble of claim 1.
  • Such chains are e.g. used for the broad transport of a web through a heat treatment device.
  • Either the chain links on the outer surfaces or the guide rails are each provided with sliding elements in order to keep the sliding friction in the guide rail low even without lubricant.
  • the sliding elements are sliding pieces.
  • the individual chain links are each composed of various individual parts such as the base body, carrier, bushings, bolts, plates, etc.
  • Two sliders are attached to each carrier. For this purpose, tabs are arranged on the sliders, which are connected to the carrier by e.g. Screws or rivets are connected.
  • the invention is based on the chain known in DE 35 10 856 A1.
  • the links of this chain are made from one piece together with a supporting part.
  • the individual links are connected by bolts.
  • the chain is not equipped with sliders. Rather, slide strips are installed as slide elements in the associated guide rails.
  • These slide rails have the disadvantage that they are subject to greater wear at the points at which the guide rails are guided in an arc.
  • the wear strips must be dismantled and replaced with new ones in the event of wear within the drying fields, that is to say in confined spaces; this is very expensive because the chain must be pulled and reassembled after the slide bars have been replaced.
  • the work for the exchange must be carried out within the device.
  • the invention has for its object to provide a chain that is simple and inexpensive to manufacture and assemble and in which the sliding elements, which are subject to a certain amount of wear and must be replaced accordingly, can be replaced quickly and without great effort. Furthermore, the replacement intervals should be increased by largely uniform wear of the sliding elements.
  • a chain link is made entirely of one piece with a carrier.
  • a U-shaped slider is attached to the chain link on each of the two long sides and fastened with only one rivet. Both a chain link and a slider can each be easily cast in a reusable form. An easy interchangeability of a slider is guaranteed because outside the dryer fields, only one fastener has to be loosened, the old slider has to be removed, a new one has to be attached and secured. Because the sliders are attached to the chain links, the wear is distributed over the entire chain instead of the arcuate parts of the guide rail.
  • Recesses in the base body according to claim 6 prevent the fastener from coming into contact with the teeth of a sprocket. This prevents destruction of the rivet head.
  • the production and warehousing as well as the assembly are simplified by identical sliders according to claim 2.
  • Bevels according to claim 8 reduce the risk of the chain tilting e.g. at joints of the guide rail.
  • Figure 1 shows a chain link vertically from above with a part cut.
  • FIG. 2 shows a section perpendicular to the running direction of the chain according to FIG. 1.
  • Figure 3 shows a side view of Figure 1 with a cut support part.
  • Figures 1 to 3 show a chain link 1 with a rectangular base body 2, two plates 3 and a connecting piece 4. In the plates 3 and in the connecting piece 4 of an adjacent chain link, not shown, there are aligned bores 5, which also form a bolt, not shown take up the chain links.
  • the bore 5 of the connector 4 is provided with a matching bush 5a.
  • the inner sides of the base body 2 are slightly beveled in the upper and lower third.
  • a supporting part 6 striving outward at right angles is arranged. It is composed of two arms 7, each of which has the shape of an elongated S, and a support bar 8.
  • the arms 7 are arranged at two upper corners of the base body 2, the top side of an arm 7 being arranged somewhat higher than the top side of the base body 2. They are provided with reinforcements in some areas.
  • a needle bar 9 is fastened on the support bar 8, for example with screws.
  • a one-piece slide 12 is fastened in the center with a rivet 13. Instead of a rivet 13, a screw, for example, can also be used as the fastening means.
  • the sliders 12 are identical for both sides.
  • a slider 12 has a U-shaped cross section, an essentially rectangular base area and is designed such that it sits on a side leg of the base body 2 without substantial play.
  • a slider 12 extends over its entire length, the total height corresponds to that of a chain link 1 plus the material thickness of the two legs of the slider 12.
  • Each recess 14 extends into the base of the slide 12 such that an arm 7 can be accommodated therein with play.
  • a chain link 1 is completely cast with the support part 6 in one piece from metal, preferably steel.
  • a slider 12 is made of low-wear plastic e.g. manufactured by injection molding.
  • a single rivet 13 per slider 12 is therefore sufficient for fixing. for example may be present at joints.

Abstract

Le problème des chaînes traditionnelles réside soit dans le montage complexe des maillons individuels avec les pièces de coulissage correspondantes, avec les difficultés de fabrication et de montage qui en découlent, soit dans l'utilisation de baguettes de coulissage, particulièrement exposées à l'usure à certains endroits, et difficiles à remplacer. Un maillon (1) complet avec élément porteur (6) est par exemple réalisé à partir d'une pièce. Chaque maillon (1) comporte deux pièces de coulissage (12) monopièces identiques. Chaque pièce de coulissage (12) est en forme de U, et vient se positionner exactement sur la branche latérale d'un maillon (1), l'assemblage s'effectue au moyen d'un seul moyen de fixation. Une pièce de coulissage (12) peut être remplacée aisément et fabriquée simplement par ex. par moulage par injection. L'invention concerne également l'apprêt des textiles.
