Definitions

  • the invention relates to a device for the advancement of leather and the like.
  • a transport device with at least one acting on the leather Drive member is provided, preferably in the form of a transport roller moving on the circumferential side opposite to the work roll and / or with a corresponding transport belt.
  • the subject of the invention also includes associated drive means and in particular transport rollers.
  • Such feed devices work largely satisfactorily in practice, provided that the transport roller or the conveyor belt moves circumferentially in the same direction as the work roller.
  • This is not the case in important areas of application, in particular not in the case of those application and printing machines for leather in which the leather passes through the contact and pressure zone on the work roll in the opposite direction to its direction of movement.
  • This fulfills the essential and often indispensable brushing or rubbing effect for the deep and even application of the working media, e.g. Paints, impregnating agents, dressings and the like.
  • the pressing of the work roll especially in connection with viscous application or working media, causes a strong hindrance to the leather feed, which can easily slow the feed movement with a non-uniform application and even lead to congestion with malfunction can.
  • the object of the invention is therefore to create a drive device or drive means or a Transport roller for leather, which enables not only a frictional, but at least an additional positive transfer of the feed force to the leather.
  • the achievement of this object according to the invention is determined by the features of claim 1 or claim 5 or claim 13.
  • the invention is particularly suitable for the introduction of thin leather into the printing zone of roller pairs, especially in dyeing machines, and here again in such known dyeing machines that work with inking rollers acting in the opposite direction to the feed direction.
  • driver arrangements with at most about 5 cm 2 , preferably with at most about 2 cm 2, per drive projection or driver have been found to be useful according to the invention.
  • Fig.l shows a dyeing machine with transport roller TW and inking roller FW (ink supply not shown), which rotate in opposite directions with respect to their circumferential movement in the working area AB.
  • the peripheral surface of the transport roller is provided with drive means AM according to the invention, here in the form of needles distributed over a large area.
  • the work station formed by the pair of rollers is preceded by a leather feed device LVZ, the transfer point UBS of which is arranged at a distance in front of the work area in the engagement area of the drive means AM on the leather with respect to the feed direction.
  • the feed device LVZ therefore brings the incoming leather edge into the positive and non-positive connection with the drive means AM before that leather gets in the opposite direction to the feed effect of the ink roller.
  • the leather feed device LVZ is provided with a leather pressure device LAV which is arranged in the engagement area AGM of the drive means AM on the leather L and in relation to the leather feed direction in front of the work area and acts in the direction against the drive means.
  • the leather pressure device comprises a wedge-like tapering pressure element with leather-facing, sliding-friendly surface that engages in the inlet bracket EW of the rollers on the leather side.
  • a rotating conveyor belt TB is guided over the transport roller TW and is provided with feed drive means AM in the manner according to the invention.
  • FIG. 4 shows a partial axial section of a transport roller with drive means according to the invention.
  • the roller body is composed of a plurality of coaxial jacket rings MR, which are centered on a roller core WK.
  • a group of drivers MN is connected to an installation unit by a common holder H.
  • 6 shows in a partial cross section of a jacket ring MR the receptacles designed as radial bores RB for needle-shaped drivers and axial inner grooves IN for receiving the brackets H.
  • the drivers are accordingly supported on the circumference of the roller core WK via their holder.
  • the outer rings with an outer jacket are made of resilient, in particular Provide elastomeric covering material HM, in which the tips of the drivers are arranged.
  • the radial bores which extend into the elastomer jacket can be made from the interior of the jacket ring.
  • the installation units consisting of carriers and brackets are also inserted from the inside.
  • the driver tips directed against the leather are arranged above the outer surface of the casing material in the inactive state.
  • the tip protrusion can be dimensioned such that the leather does not pierce and the color-bearing leather surface remains intact.
  • the driver tips are in the inactive state within the wrapping material or at least substantially aligned with the outer wrapping material surface and in the active state are arranged above the wrapping material surface.
  • a particularly efficient and successfully implemented further development of the invention provides that at least one jacket ring with an at least partially groove-free inner circumferential surface and with bores is provided for receiving needle-like or wire-shaped carriers, each fastened in holders, and that at least a jacket ring is centered directly on the jacket ring by such holders.
  • Securing the casing ring against displacement relative to the casing core can be achieved in a force-fitting manner by appropriate radial prestressing, but optionally also by additional form-locking elements.
  • Adequate form-fitting tangential thrust protection between the brackets and the casing solution is obtained with suitable dimensioning by the drivers that are firmly connected on the one hand to their brackets and, on the other hand, with a snug fit or press fit in the bores of the casing ring.

Abstract

L'invention concerne un dispositif pour faire avancer du cuir ou similaire au niveau d'une station de traitement, équipée notamment d'un cylindre applicateur de fluides liquides ou visqueux (FW) venant en contact avec le cuir et tournant dans le sens opposé au sens d'avance. L'avance s'effectue au moyen d'un dispositif de transport qui comprend au moins un organe d'entraînement venant en contact avec le cuir, se présentant de préférence sous la forme d'un rouleau de transport (TW) se déplaçant côté périphérique dans le sens opposé à celui du cylindre applicateur, et/ou une bande transporteuse correspondante. L'invention vise à créer un dispositif d'entraînement ou des moyens d'entraînement ou un cylindre de transport pour du cuir, permettant de transférer au cuir la force d'avance non seulement par liaison par friction, mais au moins également par liaison de forme. A cet effet, des moyens d'entraînement (AM) sont répartis sur la surface de l'organe d'entraînement et présentent des parties saillantes pointues ou à arêtes vives, dirigées vers le cuir, entraînant le cuir au moins en partie par liaison de forme.
