Definitions

  • the invention relates to a device for transporting workpieces to be machined or processed, in particular rods, with a basic housing or frame which can be moved on wheels, the workpieces being accommodated in a bed.
  • the object of the present invention is to develop a device of the type mentioned above, by means of which the storage can be at least partially automated.
  • the bed is connected to the basic housing via scissors and can be raised via the scissors.
  • the transport device no longer has to be unloaded by hand after reaching the storage rack.
  • the workpieces are lifted over the scissors and can then be brought into the storage frame, for example tipped over.
  • the workpieces to be transported are, for example, bar material
  • trestles are preferably also provided on both sides, which are connected to the storage frame in a suitable manner and have, for example, a sliding slope on which, after the bed has been lowered and the bar material has been lifted out can slide the bars along the bed and into the storage rack. In this way, the storage of the processing machine itself is considerably simplified. It is also possible to keep the transport device so narrow that even very narrow aisles can be driven between the individual processing machines.
  • wheels are provided to solve both problem areas, which on the one hand allow a very good turning circle, but on the other hand can be raised when the unloading position is reached, so that the basic housing stands on the floor.
  • the scissors consist of scissor struts which intersect in an axis of rotation.
  • One end of the scissor stay is connected to the base housing via an axis of rotation, while the other scissor stay has one axis of rotation with the bed.
  • the free ends of the scissor struts are designed to be slidable.
  • the one scissor strut which has an articulated connection to the bed, on the other hand forms a sliding foot which slides on a housing base when the scissors move.
  • the free end of the other scissor stay slides in a corresponding guide groove in the bed or a frame of the bed.
  • the end of the one scissor stay designed as a sliding foot engages under a crossbar in the housing when the scissors are in the rest position, ie when the bed is lowered, so that such a mounting takes place that the wheels, which are preferably located on the axle are located, which also connects the scissors struts together, are pressed out of the basic housing. Conversely, this means that the wheels are retracted when the bed is lifted, thereby lowering the basic housing.
  • At least two pairs of scissor struts are preferably connected to one another parallel to one another via the axis.
  • a rotatable spur gear ensures the maneuverability of the device, with such a rotatable spur gear being provided on both sides of the basic housing in the present exemplary embodiment. So that this spur gear is raised when the bed is lifted and thus the basic housing is lowered, it should sit on an angle lever according to the invention, which is connected via a chain or the like to another angle lever within the basic housing. Instead of the chain, other connecting elements can of course also be used.
  • the angle levers are designed so that the angle lever within the housing is attacked and rotated by the scissors when the bed is lowered so that a pull is exerted on the chain and likewise the angle lever outside, on which the spur gear is located, about a corresponding axis of rotation is rotated. This brings the spur gear into the appropriate driving position.
  • the spur gears can also be rotated on all sides on the angle levers about their vertical axis so that, for example, the device can also rotate about itself. This makes the device extremely agile.
  • the movement of the scissor struts or the scissors is preferably effected by a hydraulic cylinder which engages at least one scissor strut via a corresponding piston rod.
  • Corresponding supply devices for the hydraulics and motor devices for driving the wheels are provided in the device, so that the entire device is also designed to be self-propelled.
  • Such a device according to the invention is associated with at least one trestle, but preferably trestles on both sides, for unloading the transported goods, in particular the rods, by means of which the rods can slide into a storage position.
  • This means that the device is moved next to a storage rack for the bars and then the bars are raised to approximately the level of the filling opening of the storage rack. Then the trestles are placed under the bars and the scissors are lowered again. The bars then remain on the trestles and slide along them into the storage rack.
  • the invention further provides that a rope or similar traction means is located between the side posts of the bearing frame.
  • This rope is on a rope ten post while being placed on or near the opposite post over a roller. The free end of the rope is then loaded with a counterweight.
  • the rope is only guided over an edge of the opposite side post.
  • the weight is adjusted so that it yields a corresponding pressure of a corresponding number of rods, so that these are lowered over time. On the one hand this results in an orderly placing of the rods and on the other hand no noise is caused.
  • Figure 1 is a perspective view of an inventive device for transporting rod material in an unloading position
  • FIG. 2 shows a side view, partially broken away, of the device according to the invention according to FIG. 1 in a further position of use;
  • FIG. 3 shows a partially broken side view of the device according to FIG. 1 in a further position of use
  • FIG. 4 shows a top view of the device according to FIG. 1.
  • a device R according to the invention for transporting, in particular, rods 1 which are to be further processed is, according to FIG.
  • Another possibility according to the invention consists of a rope or the like. to stretch transversely from one post of the bearing frame 2 to the other, the rope being fixed to one post, while it runs on a roller or the like on the other post and a weight is then attached to it. In this way, a transverse lying of the rods is avoided during or after filling the storage rack.
  • the rods 1 lie for transport in a bed 4, which is essentially formed by an approximately rectangular frame 5 and side struts 6 projecting therefrom.
  • This bed 4 rests on scissors 7 and can be raised or lowered by means of the scissors 7.
  • the bed 4 is shown in the raised end position.
  • jacks 8 and 9 are placed under the bars 1 on both sides, each jack consisting of a sliding slope 10 and a supporting leg 11.
  • one end of the sliding bracket 10 is inserted into a corresponding holding opening 12 of the storage rack 2. If the bed 4 is now lowered by means of the scissors 7, the rods 1 can slide into the bearing frame 2 on the sliding slope 10 and lie there on the cross struts 3.
  • the scissors 7 consists of two pairs of intersecting scissor struts 19 and 20. These scissor struts are connected to one another via the axis 16, so that the axis 16 also forms a fulcrum for the scissors 7.
  • each scissor strut 20 arranged parallel to one another are connected to one another at one end in the housing via an axis of rotation 21.
  • the scissor stay 20 is then supported against the bottom of the profile.
  • this sliding foot 24 slides onto a housing base 25 in the y direction.
  • the sliding foot slides in the opposite direction y and engages under a cross bar 26 which forms an abutment.
  • the scissors 7 can now be closed further, the side wheels 17 and 18 emerging through an opening 27 in the housing base 25 and thus lifting the base housing 13.
  • the lowering of the spur gears 14 and 15 in the driving position also takes place by the lowering movement of the scissors 7.
  • each of these angle levers 28 has an axis of rotation 29 fixed to the housing, this axis of rotation 29 between a push lever 30 and a pull lever 31 is arranged. If a scissor strut 19 or 20 presses on the pressure lever 30, if necessary, via a fitting 32, the angle lever 28 rotates about the axis of rotation 29, the pull lever 31 pulling on a chain 33.
  • This chain 33 is connected outside the basic housing 13 to a pull lever 34 of a further angle lever 35, which in turn has an axis of rotation 37 between the pull lever 34 and a push lever 36.
  • the spur gear 14 or 15 is seated on the pressure lever 36, wherein it is connected to the pressure lever 36 via a corresponding fastening fork 38 or rotates relative to the pressure lever 36 about an axis of rotation 39 which is only indicated by dash-dotted lines.
  • the entire device R is steered by this rotation about the axis of rotation 39.
  • a movement of the scissors 7 causes both the side gears 17 and 18 and the spur gears 14 and 15 to be lowered into a driving position.
  • the scissors movement takes place by means of a hydraulic cylinder 40.
  • This hydraulic cylinder 40 has a pivot point 41 fixed to the housing, with the pivot point 41 of the cylinder in the exemplary embodiment shown
  • a piston rod 43 which leads out of the cylinder 42, is connected to the two parallel struts 19 between the axis 16 and the axis of rotation 23, an axis of rotation 44 only being indicated for this purpose.
  • a supply for the hydraulic cylinder 40, not shown, is arranged in a housing box 45.
  • corresponding transmission links and connecting chains are provided between the electric motor and the axis 16, which are neglected in the present exemplary embodiment for the sake of clarity.
  • Batteries 46 which are provided in a front housing box 47, serve to supply both the electric motor and the hydraulic device.
  • the spur gear 15 is associated with a drawbar frame 48, of which a drawbar 49 projects according to Figures 2 and 3.
  • This drawbar 49 ends in a switch box 50, on which lever switches 51 and 52 are located on both sides.
  • a lever motor 53 ie the electric motor mentioned above, is actuated via these lever switches 51 and 52, while the other lever switch initiates the hydraulic supply.
  • the drawbar 49 is otherwise articulated to the drawbar frame 48 so that the drawbar 49 can be moved in the direction z. For driving, this drawbar 49 is pulled, the spur gears 14 and 15 enabling cornering.
