Definitions

  • the invention relates to a flat rod for a card according to the preamble of patent claim 1.
  • a flat bar as part of a revolving lid, there is an internally hollow supporting body made of extruded aluminum, the hollow space being penetrated in the longitudinal direction by a steel rod.
  • a block-shaped support element which is fixed by a screw, is pushed onto the two ends of the rod protruding from the cavity.
  • the screw is axially engaged with a thread at the end of the rod.
  • the two end head parts slide on the fixed sliding guides of the card.
  • a lid chain is arranged between the end face of the support body and the block-shaped end head part, the links of which are penetrated by the ends of the rod.
  • the flat chain pulls the flat bars over the sliding guides and ensures that the end head parts are pressed onto the sliding guides.
  • the flat bar is complex in terms of construction and assembly.
  • the production of the block-shaped support elements is complicated.
  • Another disadvantage is that considerable friction losses occur between the block-shaped end head parts and the sliding guide.
  • the cover chain is elongated, becomes contaminated with dust and fiber fly, and the chain links need to be serviced with lubricants, i. H. overall, it is constructive and complex in terms of assembly and operationally disadvantageous.
  • the covers clamp an endless flexible band by means of a clamping plate and a screw.
  • the screw has the task of connecting the cover to the clamping plate.
  • the function of the clamping plate is to guide the cover on the sliding surface of the flexible sheet. Fastening the clamping plate on the cover using an additional fastening element is constructive and complex in terms of assembly.
  • On the lid for clutter according to DE-C-384 195 is by a rivet attached to the ends of a piece that slides with a surface on the cover slide.
  • a cover head is present at both ends of the one-piece flat rod, which slides with its lower surfaces on the sliding guide.
  • a flat bar known from US-A-4 827 573 comprises a steel tube drawn through a profile shape. At both ends of the flat bar there are massive head pieces, on which holding elements for attaching a drive belt are attached. These head pieces are connected to the flat rod either by welding or with rivets or screws so that they can be replaced when they become unusable due to wear. It has been found that in some cases the welded connection leads to tension in the flat rod, and then the entire flat rod has to be replaced. The same also applies to the screw and rivet connection, i.e. H. the connecting force to be used (screw rotation or pressure when riveting) must firstly remain constant and constant for all flat bars within a certain tolerance range in order to avoid excessive compressive stresses (i.e.
  • the known flat bar has parallel and then converging side walls down to a certain height.
  • the end head part consists of three elements, the head piece and the two-part holding element, which are arranged axially with respect to the support body. Only the head piece slides on the slide guide, while the holding elements and the drive element are outside the slide guide.
  • the disadvantage here is that the drive element acting outside the sliding guide exerts an undesirable lever effect and thus a bending moment on the head piece and on the support body.
  • the head piece does not slide dimensionally with the sliding guide in this way, which can lead to disruptive canting.
  • the steel tube has a high specific weight, so that the flat rod is too heavy for the drive, which is particularly important given the large number of flat rods.
  • the replacement of the worn head pieces is complex in terms of assembly, since the welded or riveted connections of the head pieces have to be loosened on the supporting body and must be reattached after the replacement.
  • the card can only be repaired when the card is at a standstill, which leads to considerable malfunctions and production losses. This document forms the preamble of the first claim.
  • the invention is based on the object to provide a flat rod of the type described above, which avoids the disadvantages mentioned, which is particularly simple in terms of construction and assembly, and in which the support element (end head part) slides on the sliding guide of the card in a dimensionally stable and low-friction manner.
  • the drive element presses the element directly from above onto the sliding guide, so that undesirable bending moments on the element and on the supporting body are avoided and dimensionally accurate sliding of the element on the sliding guide is achieved.
  • the design of the supporting body from a light metal extruded profile is of particular structural, functional and economic advantage. Manufacture and assembly of the support body are considerably simplified and, in addition, lower driving forces are required for the propulsion because of the low specific weight. Because at least the sliding area of the element consists of a wear-resistant material, a significantly increased service life is achieved. Disruptive business interruptions and production losses are avoided.
  • the element comprises both the sliding area and the fastening area results in a very simple construction of the end head parts.
  • the assembly of the flat rod is simplified, which improves compliance with tolerances, i.e. dimensional accuracy.
  • this construction enables the selection from a large number of material pairings which, compared to the prior art, leads to a reduction in friction and thus to a longer service life.
  • the element is advantageously in one piece.
  • the element is expediently in direct engagement with the supporting body.
  • the element preferably engages with the supporting body in the region of the end face via an auxiliary carrier known per se.
  • the element is advantageously permanently connected to the subcarrier.
  • Each end head part expediently has two elements. This reduces its tendency to tip over and the sliding friction.
  • the sliding area of the element is advantageously made essentially linear.
  • the sliding area is preferably designed as a sliding surface.
  • the fastening area is expediently a cylinder. This provides an adaptation to the curved cover deflection guides without a chamfer or the like being necessary.
  • Commercially available hardened and ground steel needles allow the flat rod to be manufactured economically. The steps of cutting, drilling and inserting the pins make the flat rod particularly easy to manufacture.
  • the fastening area is advantageously a polygon.
  • the sliding area of the element preferably consists of a wear-resistant material.
  • the elements are expediently fastened in the end face of the foot part of the hollow extruded profile.
  • the elements pins made of hardened steel or the like are advantageous.
  • the sliding surface of the elements is preferably ground, finely ground and / or polished.
  • the elements are expediently fastened with their fastening region in recesses in the supporting body.
  • the elements with their fastening area are advantageously fastened in a bore in the end face of the supporting body.
  • the lower limit of the elements is preferably at a distance a above the foot surface of the support body.
  • the elements are expediently arranged in the working direction D at an angle alpha with respect to the longitudinal axis of the support body in such a way that their sliding regions point opposite to the working direction with respect to their fastening regions.
  • the support body is advantageously an extruded profile made of a light metal, for. As aluminum, or a light metal alloy.
  • a specifically light material e.g. B. aluminum
  • the support body can be manufactured in a simple manner by cutting to length a commercially available extruded profile.
  • Aluminum allows the production of a light flat bar.
  • the extruded profile is preferably a hollow profile. In this way, the deflection of the support body and thus of the flat bar is reduced over the width of the card. In addition, aluminum is saved through the inner cavity, so that the supporting body is more economical and also easier to manufacture.
  • the cross section of the recesses is expediently circular.
  • a stiffener is preferably arranged in the recesses between the elements.
  • the cross section of the recesses is advantageously polygonal.
  • the stiffening is expediently a steel profile.
  • the end head parts of the flat rod have low-wear, low-friction and dimensionally precise sliding surfaces.
  • the use of a flexible belt enables the drive element to have a constant length; the flexible belt is maintenance-free, structurally simple and allows the traveling cover to be easily installed.
  • a connecting element is advantageously in engagement with the elements and with the flexible belt.
  • the element expediently engages the flexible strap indirectly.
  • the connecting element is preferably fastened with one end in or on the end face of the supporting body.
  • the elements advantageously have a distance between their free end faces and the connecting element.
  • the connecting elements, bristles, brushes, elastic wiping elements or the like expediently engage the sliding guide in a cleaning manner.
  • the upper region of the foot part is preferably arranged at an acute angle alpha to the vertical.
  • the areas of the elements which remain free at the top advantageously engage a support element when the flat bars are returned.
  • the support body and the end head parts expediently form at least three assembled components.
  • the flexible straps preferably engage directly with the wear-resistant end head parts.
  • the elements are advantageously fastened in or on the end head parts.
  • the elements expediently display a wear-resistant coating, plating, which is located on their sliding area.

  • the elements are preferably connected to the recesses by resilient clamping.
  • the elements are advantageously connected to the recesses by gluing.
