Definitions

  • the present invention relates to a device according to the preamble of patent claim 1.
  • a device of this kind is disclosed in GB-A 2 015 695. It shows a device in which a pressure cylinder jacket and a pressure piston are arranged axially within the cylinder jacket of the conveyor roller.
  • the pressure piston is firmly connected to a piston rod which is axially displaceably mounted in one of the two end PTO shafts of the conveyor roller. Outside the PTO bearing, the piston rod is provided with an external thread and is mounted in a fixed nut thread.
  • the pressure piston in the pressure cylinder jacket can be moved and the pressure in the liquid within the cylinder jacket can be increased or decreased.
  • the position of the pressure piston is secured by an adjusting nut screwed onto the external thread. A change in the pressure in the conveyor roller during operation is therefore not possible and the use of automatic adjustment means is difficult.
  • the non-generic DE-C 29 33 775 shows a rotatably mounted shaft with axially parallel, evenly distributed over the circumference hoses. These are surrounded by ring-shaped brake bodies pushed axially over the shaft. Races are rotatably mounted on these brake bodies.
  • the hoses can be pressurized with a pressure medium via an axially extending channel in the shaft. Depending on the level of pressure in the hoses, the brake bodies are more or less radially stretched and brake the races accordingly. It is not intended to apply high pressure to the hoses.
  • the object of the present invention is to improve a device of the type mentioned at the outset in such a way that the pressure of the conveying roller can be adjusted during operation by means which operate automatically and that the pressurization can be carried out by the compressed air network which is regularly present in manufacturing plants.
  • a conveyor roller 3 is rotatably mounted in bearings 2 between two parallel end plates 1.
  • the conveyor roller 3 has a penetrating axial shaft 4 which carries at one end a pinion 5 which is connected to a motor which is not shown.
  • Circular end walls 6, which are tightly connected to a cylindrical jacket 7, are firmly connected to the shaft 4.
  • An axial channel 8 is arranged in one end of the shaft 4, which branches in the region of the cavity 9 enclosed by the jacket 7 and whose branches open into the cavity 9. At the outer end of the shaft 4, the channel 8 is closed by a screw 10. Further sealing elements are arranged between the cavity 9 and the end walls 6.
  • the right end of the shaft 4 passes through a section of smaller diameter diametrically through the pressure cylinder 12 of a hydro-pneumatic pressure transducer 15 and is rotatably supported therein with pressure-tight bearings 13.
  • the channel 8 In the area of the pressure chamber 14 of the pressure cylinder 12, the channel 8 has a branch opening into the pressure chamber 14, so that the pressure chamber 14 communicates with the cavity 9.
  • a pneumatic cylinder 16 Connected axially to the pressure cylinder 12 is a pneumatic cylinder 16 which can be acted upon by a pressure medium source (not shown) with a gaseous pressure medium via a line 17.
  • line 17 are means to selectively build up and maintain a certain excess pressure in the cavity 9.
  • the end walls 6 and the shaft 4 are preferably made of steel, whereas the cylinder jacket 7 consists of a material which can be deformed elastically within a pressure range. Light metal alloys are particularly suitable for this.
  • the cavity 9 is pressurized by the pressure transducer 15, the diameter of the conveyor roller 3 increases (dash-dotted line in FIG. 2). As the diameter increases, the length of the material section conveyed per roller revolution increases. The thinner the material thickness, the greater the overpressure in the cavity 9 is chosen or vice versa, such that the radius from the shaft axis to the center of the material web (neutral fiber) remains constant.
  • the cylinder jacket 7 has annular ribs 18 spaced apart from one another on the inside. Under pressure, the outside of the cylinder jacket 7 is given a corrugated shape, as is indicated by dash-dotted lines in FIG. 3, which gives the material web a more stable lateral guidance.
