Definitions

  • the invention relates to a press for textile fibers with at least one press ram and a press box, the walls of which are arranged pivotably on a support frame or on one another and can be locked together in the closed position.
  • Presses of the type mentioned are known in various embodiments and are used in particular for producing large bales from short or long fibers.
  • the fibers in the press box become denser and press against the box walls with relatively great force, which often causes difficulties when opening the locking device. After the pressing process, this is under such high prestress that it is difficult to open in many cases.
  • the invention has for its object to provide measures to ensure proper closing and opening of the locking device for the swing-open walls of the press box.
  • the invention provides that the locking device is a piston-cylinder device pivotally mounted on a wall with a locking member at the free end.
  • the locking device only works non-positively and holds the walls to be locked together solely on the basis of the closing force exerted by the piston-cylinder device. As soon as the pressure in the piston-cylinder device drops, the interlocked walls of the press box open. It is completely irrelevant how high the internal pressure was in the press box. It can never cause the locking device to jam, as is the case with mechanically locking devices.
  • FIG. 1 for the manufacture of bales from textile fibers has at least one press ram 2 and a press box 3, the walls 4 and 5 or 6 and 7 of which are pivotably arranged on a support frame 8 or against one another and can be locked together in the closed position.
  • the upper end of the press 1, like the drive for the press die 2, is not shown in the figures, since these parts are known in principle and are not the subject of the invention.
  • the two opposing walls 4 and 5 of the press box 3 are pivotally mounted on the support frame 8 on axes 9, 10.
  • the wall 6 is mounted on the one wall 5 so as to be pivotable about an axis 11 and the last wall 7 is articulated on the two opposing walls 4 and 5 with the aid of links 12, 13, 14 and 15. If the two walls 4 and 5 therefore pivot apart from the closed position according to FIG. 2 into the open position according to FIG. 3, the wall 7 moves a bit outwards perpendicularly to its plane.
  • the handlebars 12 - 15 supporting the wall 7 are expediently curved, as can be seen from the figures.
  • the wall 6 is only pivotably pivotable by a few degrees relative to the wall 5 and, according to the exemplary embodiment, is provided with a locking device 16.
  • This locking device 16 consists of piston-cylinder devices 17 which are pivotally mounted on the wall 5 and a locking member 18 at its free end. 19 have.
  • Two piston-cylinder devices 17 are expediently mounted on the wall 6 in brackets 20 and 21 about axes 22 and 23 and can be moved from the closed position shown in FIG. 2 to the position shown in FIG. 3 with the aid of piston-cylinder devices 24. on "swivel.
  • the locking member 18 of the locking device 16 is a rigidly arranged at the free end 19 of the piston rod 25, approximately hemispherical or spherical holding piece, the diameter of which is larger than the piston rod diameter.
  • the locking member or holding piece 18 with its hemispherical holding surface 26 is assigned a holding part 27 with a dome-shaped holding surface 28 with an entry slot 29 on the other wall 4. Details of this are shown in FIGS. 3 and 4.
  • the piston rod 25 enters the entry slot 29, whereupon the piston is moved into the interior of the cylinder 3o of the piston-cylinder device 17.
  • the holding piece 18 lies in the dome-shaped holding surface 28 and closes the press box non-positively.
  • the closing pressure in the cylinder 3o is first gradually reduced, for example by switching on a throttle, until the bale located in the press box no longer exerts pressure on the walls 4-7. Then the piston rod 25 is moved outward until it has completely released the holding part 27 and the walls can be pivoted apart.
  • each of the two pivot axes 9 and 10 of the walls 4, 5 is supported on a spring 34 which is arranged in a bore 35 in the base frame or support frame 8.
  • the walls 4 and 5 L are preferably rigidly connected to the associated axis 9 and 10 and are thereby acted upon vertically upwards by the springs 34 or the walls 4, 5 are supported on the very strong springs 34 .
  • the walls 4 and 5 are connected via brackets 36-38 to the axes 9 and 10, respectively, which are guided in lower bearings 39 and upper bearings 4o or are supported. From the upper bearings 40, the axles 9 and 10 reach out a little and each carry a gear 41 and 42, respectively, which are connected to each other in opposite directions via intermeshing intermediate wheels 43 and 44.
  • a swivel lever 45 protrudes from the one gear wheel 41, which is adjustable by a piston-cylinder device 46, which is articulated with its one end 47 on the swivel lever 45 and with its other end 48 on a box top part 49 of the press 1. As soon as the piston-cylinder device 46 pivots the pivot lever 45, the two walls 4 and 5 open and close synchronously.
  • the support frame 8 is essentially U-shaped or yoke-shaped and comprises a base plate 50 and a bearing plate 51 on which a plurality of pressure pieces 52 are arranged for each press box wall 4-7. Two pressure pieces 52 are preferably assigned to each wall, as can be seen from FIG. 3.
  • the springs 34 are a lifting device which ensures that the walls 4-7 open and close without contact.
  • the press die 2 works in the press box 3 against a base 54, but it goes without saying that instead of the rigidly arranged base 54, a lower, second movable counter-die could also be provided without thereby leaving the core of the invention.
  • the bottom 54 rests on an intermediate piece 55, which is located between the pressure pieces 52, 53 and is arranged on top of the bearing plate 51.
  • the U-shaped support frame has a support member 56 above the bearing plate 51 or the base 54 and laterally or behind the axes 9 and 1o, the upper end 57 of which projects horizontally and the upper bearings 4o for the axes 9 and 1o and also carries the box top 49 with the press ram 2.
