Definitions

  • the invention relates to a device for changing the rollers in roller presses with two rollers lying side by side.
  • the bearing housings are generally not only guided in the longitudinal direction of the upper and lower frame part, but also transversely thereto. For this purpose, the bearing housings can overlap the sliding surfaces on both sides. Tilting the roller when pulling it out or reinserting it easily leads to jamming and possibly damage to the sliding surfaces. Great care is therefore required when pulling out the rollers by means of cables. Even known devices that work with hydraulic cylinders offer no guarantee that the rollers will actually be moved without tilting.
  • the object of the invention is to provide a device which is simple in its construction and which ensures, with great reliability, a parallel guidance of the rollers during extraction and reinsertion.
  • a connecting element which can be screwed to the bearing housings in each case a roller and in / on which a motor-driven drive shaft is mounted, which is parallel to the roller axis and at the ends of which are provided with toothed drive wheels, which each cooperate with teeth that are arranged parallel to the sliding surfaces on the outer sides of the connecting pieces.
  • the roller press shown in the drawing is of conventional construction with a frame which has a lower frame part 2 and an upper frame part 4.
  • the top of the lower frame part and the underside of the upper frame part are each formed over their entire length as sliding surfaces.
  • the lower frame part 2 and the upper frame part 4 are connected to one another via an intermediate piece 6.
  • a screw connection is preferably provided as a connection.
  • the upper and lower frame parts are each connected via a connecting piece 8, which is shown in the drawing in a horizontal position, but is normal in normal operation and each has a lower cross pin 10 and an upper cross pin 12 with the lower or upper frame part is connected.
  • bearing housings 14 are arranged on both sides between the sliding surfaces, in which the rollers 16, 17 are rotatably mounted.
  • the bearing housings 14 are displaceable in the longitudinal direction and are expediently guided in the transverse direction, for example by lateral shoulders 13.
  • the connecting pieces serve as abutments for the bearing housings 14 and 15, the bearing housing 14 on the left in FIG. 1 directly against the connecting piece 8 1, on the right side between the connecting piece 8 and the right bearing housing 15 a hydraulic support (not shown in the drawing) is provided, which in turn bears against the connecting piece 8 and has hydraulic pistons against which the bearing housing 15 bears.
  • rollers 16 and 17 Details of the mounting of the rollers 16 and 17 in the bearing housings 14 and 15 are not shown in the drawing, since this is done in the usual way.
  • the rollers 16 and 17 themselves are only indicated by dash-dotted circles.
  • the connecting pieces 8 are detachable at least with their upper end by loosening the cross bolts 12 from the upper frame part 4.
  • the connection between the connecting piece 8 and the lower frame part 2 can be designed such that the connecting piece 8 can be pivoted about the lower transverse bolt 10 into the horizontal. In this position the two connectors 8 are shown in the drawing.
  • connection piece at the lower end and to provide means between the connecting piece and the lower frame part, by means of which the connecting pieces can be connected to the lower frame part after being moved into the horizontal position in such a way that the surface 18 lying on top , which is preferably the inside of the connecting piece in the active operating position, forms a sliding surface which is flush with the sliding surface 20 on the upper side of the lower frame part 2, both in height and to the side.
  • the rollers can be pulled out of the press frame with their bearing housings 14 between the lower and upper frame part, to the extent that they lie freely on the connecting pieces 8 in their horizontal position in front of the roller frame, so that they can then be lifted with a crane .
  • a device 22 is provided, which is shown on the left in FIG. 1.
  • This device 22 has a connecting element, here a connecting plate 24, which can be connected to the bearing housings, preferably screwed to the end face 26 of the bearing housing directed against the connecting pieces by means of screws 23.
  • a drive shaft 30 is rotatably mounted on the connecting plate 24 in bearings 28.
  • a geared motor 32 is flanged in front of the connecting plate 24, in such a way that its output shaft 34 lies parallel to the axis of the drive shaft 30, which in turn is arranged parallel to the axis of rotation of the roller in the bearing housing 14.
  • a sprocket 36 is fastened on the output shaft 34 of the geared motor 32 and acts on a sprocket 40 fastened on the driven shaft 30 via a drive chain 38.
  • Sprockets 42 are attached to the free ends of the drive shaft 30. These interact with roller chains 44 which are arranged on supports 46 which are held on brackets 48 on the outside of the connecting pieces 8.
  • the carrier 46 and the roller chains 44 arranged thereon extend in height and in the longitudinal direction parallel to the sliding surfaces 18, 20 onto the lower frame part 2 or the connecting piece 8.
  • the geared motor 32 is preferably an electric motor, which is provided with a loose connecting cable and can be supplied with power, for example, from a socket.
  • the transmission can also be driven by an air motor.
  • the connecting pieces 8 are detached from the upper frame part 4 by pulling out at least the upper cross bolts and brought into a horizontal position in which the sliding surface 18 which is normally in contact with the bearing housing 14 is aligned with the sliding surface 20 of the lower frame part. Then the device 22 is screwed with its connecting plate 24 to the bearing housing of a roller. Then the geared motor 32 is switched on with the corresponding direction of rotation. The roller with its two bearing housings 14 is pulled out of the press frame in synchronism via the drive sprockets 42 which engage with the roller chains 44 on the connecting pieces 8. After reaching the end position, which is shown on the left in Fig. 1, the mounting plate 24 of the device is detached from the bearing housings and removed deposited on the connectors.
  • the device 22 is connected with its connecting plate 24 to its bearing housing 14. After switching on the geared motor in the opposite direction of rotation, this roller is then pushed into the frame in a synchronized synchronism of the two bearing housings.
  • the devices 22 are represented in FIGS.
  • roller chain 44 is fastened at one end to the carrier 46 with a conventional anchor plate 50, while a tensioning bolt 52 with a tensioning bolt block 54 is provided at the opposite end of the carrier.
  • the roller chain can be lowered at its end over an area 56, as shown on the left in FIG. 3.
  • the clamping bolt 52 is then at a corresponding angle to the sliding plane 18.
  • the carriers 46 with the roller chains 44 are firmly connected to the connecting pieces and remain on the press even during operation. It is therefore only necessary to store the device 22 separately. As shown in FIG. 1, the carrier 46 extends at the free end of the connecting piece beyond its end face and thus projects over the upper frame part 4 during the operating position of the connecting piece out. In Fig. 1 on the right side, the way in which the roller with its bearing housings has to be moved is larger by the width of the hydraulic pressure device than on the left side. For this purpose, the carrier 46 is guided with the roller chain 44 beyond the inner end of the connecting piece 8 and then extends in the operating position of the connecting piece to below the lower edge of the lower frame part 2. However, there is normally sufficient space here by the base frame on which the press is usually set up.
