Definitions

  • the invention relates to a three-way stacker according to the preamble of patent claim 1.
  • Such a three-way forklift is out about DE 31 41 215 A known. It is used, for example, as a rack conveyor. At the front end a soschub- or guide frame is arranged transversely to the longitudinal axis of the device. Depending on the version of the side push frame is fixedly connected to the vehicle or guided approximately on a mast in height. Finally, it is also possible to attach the side push frame to the front of the cabin of the vehicle, which is movable in total on the mast in height. In this case, the three-way stacker is a picking device. On the side push frame, a boom is moved horizontally.
  • the boom consists of two sections, namely a first section guided on the side push frame and a second section rotatably mounted about a vertical axis.
  • a first section guided on the side push frame and a second section rotatably mounted about a vertical axis.
  • At the second section is either directly a holder for a load supporting means, such as a fork attached or, for example, an additional mast on which the fork holder can be moved in height.
  • a load supporting means such as a fork attached or, for example, an additional mast on which the fork holder can be moved in height.
  • a preferably hydraulic drive the second section and thus the load fork or the mast can be pivoted about a vertical axis in an angle range of 0 to 180 °.
  • the hydraulic lines for supplying the drives to the moving parts are combined and guided in a suitable manner so that they can follow the horizontal movement of the boom.
  • To transfer weight from the boom on the side push frame rollers are arranged on the boom, which cooperate with
  • the invention has for its object to provide a three-way stacker in which the wear on gears and racks is minimized in ensuring a smooth running of the boom on the side push frame.
  • the spacer rollers can be rotatable or preferably non-rotatably seated on the torsion shaft.
  • the Abstandsröllen are each arranged on the side facing away from the end of the torsion shaft of the gears and the guideways respectively in the space between the racks.
  • each rack contains at least one parallel track, with which the spacer rollers cooperate.
  • the racks can also form a track for a guide roller of the boom.
  • the upper rack has an upper surface on which rests about a horizontal axis rotatable guide roller.
  • the torsion shaft is rotatably mounted in the first section of the boom.
  • an embodiment of the invention provides that the torsion shaft is mounted in an upper and a lower bearing component, for example a bearing plate attached to the boom, wherein the guide roller is in turn rotatably mounted on the bearing member.
  • the wear on the tooth flanks of the gear and rack is reduced, which increases the service life.
  • the smoothness of the boom on the side push frame improves.
  • the adjustment work can be reduced during assembly.
  • the invention enables a compact and inexpensive design, since the torsion wave is used as a carrier part.
  • a side push frame 10 of a three-side forklift is designated by 10.
  • the three-way forklift is not shown otherwise. In that regard, about DE 31 41 215 A1 Referenced.
  • the side push frame 10 is mounted horizontally on the front of the three-way forklift, for example on the vehicle itself or on a mast or on a height-adjustable guided on the mast cab.
  • the side push frame has a cross-sectionally U-shaped frame section 12, whereby a channel 14 is formed.
  • a flat rail 16 is attached, for example by screwing.
  • a rack 18 is attached, for example, also by screwing, which is not shown in detail.
  • Rail 16 and rack 18 are horizontal.
  • a further flat rail is attached. While the flat sides of the rail 16 extend horizontally, the flat sides of the rail 20 extend vertically.
  • a rack 22 is attached on the rail 20, a rack 22 is attached. The toothing of the rack 22 does not extend completely across the width of the rod, but a slightly recessed portion 24 is provided which forms a horizontally extending vertical track 26.
  • the rail 16 also forms on the side facing the toothing of the rack 18 side a track 28. This is also slightly set back relative to the toothing of the rack 18.
  • the raceways 26, 28 extend in a common plane. However, they can also lie in parallel planes. In addition, they run parallel to the parallel racks 18, 22.
  • a boom 30, which extends generally perpendicular to the frame profile 12, has an upper bearing plate 32 and a lower bearing plate 34, which on a stable Housing are mounted, which is indicated at 36.
  • the bearing plates 32, 34 rotatably support a torsion shaft 38, on which an upper gear 40 and a lower gear 42 are arranged rotationally fixed.
  • the gears 40, 42 mesh with the teeth of the racks 18, 22.
  • the torsion shaft 38 is driven in rotation by a hydraulic drive 46.
  • two guide rollers are rotatably mounted on the underside about a vertical axis, one of which can be seen at 50 in Fig. 2.
  • the guide rollers 50 cooperate with a back in Fig. 1 guideway of the rack 18.
  • Fig. 2 On the lower bearing plate 34 also two guide rollers are rotatably mounted, one of which is shown in Fig. 2 at 52. They interact with a guideway on the rear side (FIG. 1) of the toothed rack 22.
  • the guide rollers 50, 52 receive the weight moment of the boom 30 about an axis parallel to the longitudinal axis of the side push frame 10.
  • a further guide roller 54 is rotatably mounted about a horizontal axis. It cooperates with an upper guide track of the rack 18 and absorbs the weight of the boom. Preferably, two such rollers can be provided.
  • the bearing plate 60 On the housing 36 of the arm 30 is horizontally extending at the lower end of an arm 58 is attached to which a further, transversely extending bearing plate 60 is attached.
  • the bearing plate 60 carries a rotary arm 66 via an upper arm 62 or a lower arm 64. Its housing is supported by a block 68 from a mast 70, in which a lifting cylinder 72 is guided, which in turn is supported on the block 68.
  • the lifting mast 70 can be rotated about a vertical axis 72a, preferably between 0 and 180 °.
  • a carriage or fork carriage 76 On the mast 70, a carriage or fork carriage 76 is guided in height, which can be adjusted by means of a chain, not shown, and the lifting cylinder 72 in height.
  • a sensor bearing is indicated at 78, with which the lifting height of the carriage 76 is determined.
  • the hydraulic power supply for the drives 46, 66 and the cylinder 72 must of course take place from the carrier vehicle, wherein the hydraulic lines are summarized accordingly (not shown) and are guided by the profile frame 12. They may be guided in a loop (not shown) in the channel 14, so that the boom 30 can move freely along the side push frame 10.
  • the boom 30 moves horizontally according to the double arrow 80.
  • the fork lift carrier 76 moves along the double arrow 82 and upon actuation of the rotary drive 66, the mast 70 rotates about the axis 72a according to the double arrow 84 ,
  • the gears 40, 42 rotate, causing the boom 30 to move along the racks 18, 22.
  • the guide rollers 50, 52 and 54 are based on the facing guideways or surfaces of the racks 18, 22 from.
  • an upper spacer roller 86 and a lower spacer roller 88 As further seen in Figures 1 and 2, sitting on the torsion shaft 38, an upper spacer roller 86 and a lower spacer roller 88.
  • the spacer roller 86 rolls on a guideways 26, 28 from. With the help of the spacer rollers 86, 88 a predetermined distance between the gears 40, 42 and the racks 18, 22 is set.
