Definitions

  • the invention relates to an industrial truck, in particular a driverless truck Transport vehicle, with lifting devices that can be lifted, swiveled and are movable.
  • Driverless transport vehicles are land-based subsidies with their own Travel drive that is automatically controlled and with its own, mostly battery-generated power supply. In the production integrated They are used for flexible linking of manufacturing facilities and Assembly places used. They are also used in picking and in the operation of rack storage. The material to be transported is normally carried by active load handling attachments on the industrial truck are grown. Active load handling devices allow the vehicle to carry the load automatically and automatically at the starting point without the aid of other funding can pick up and deliver at the destination.
  • a transport task that occurs particularly frequently consists of the provided palletized goods to be conveyed floor level, from above-ground transfer devices, Trestles or from shelves to take over automatically, via a to transport the specified route and level with the floor, to above ground Transfer devices, trestles or in shelves.
  • the Load suspension devices (usually these are forks) must therefore be horizontal Extending movements to the left and right or to the rear and vertical Can perform movements (lifting, lowering).
  • FIG. 1 shows Above the possibility of lifting and lowering the forks and in the lower one Partial view in the top view both the swivel option to the left and right as well the ability to move around goods that lie next to the lane of the vehicle, record or deliver there. Because in these versions the loading unit on the forks of the load handler not only during the load handler and load delivery but also when transporting the load from the receiving to the The point of delivery protrudes beyond the wheel contact area of the vehicle Vehicle to achieve sufficient stability with a counterweight be equipped.
  • loading units on the right or also being able to pick up on the left at floor level is an improvement in the stability of the tipping during the transport process by means of fixed, conventional forklift trucks Wheel arms, in the driverless transport vehicle versions with Swivel push fork not possible.
  • the heavy counterweight required increases the total weight of the vehicle, resulting in increased wheel pressures and therefore greater floor load, higher wheel wear, greater driving resistance. This also results in the need for larger traction motors and a higher one Stress on vehicle batteries.
  • the object of the invention is therefore to provide an industrial truck, in particular a driverless one Transport vehicle to improve in that the disadvantages mentioned be avoided.
  • a vehicle that has a C-claw having.
  • the C-claw is a C-shaped arch that is suitable for a vertical Center axis to be pivoted so that the open position of the C's both left of the Vehicle as well as behind the vehicle and to the right of the vehicle.
  • the load suspension device is then arranged, which can carry out a stroke and is telescopic to move loads from outside the Pick up vehicle contour from the ground and into the interior of the vehicle contour bring to. This significantly reduces a tilting moment.
  • the load suspension device according to the invention is so designed to be used as a separate vehicle or as a universal vehicle Attachment to various types of driverless transport vehicles can be attached from which it obtains the necessary energy supply. In this way, driverless transport vehicles that were previously only available as Tractors are used, or only equipped with passive load handling devices are retrofitted with a universal active load handler.
  • the driverless transport vehicle shown in Figure 2 consists of the Main components vehicle stem 1 and load carrier 2.
  • the chassis of the Vehicle stem 1 contains the drive and steering unit, the power supply, the Control and the necessary safety devices. It is based on that steered drive wheel in the middle and over several castors 1.1, here two pieces the road.
  • Two spherical bearings 3.2 on one serve as a connection to the load carrier Bracket 9.
  • the load carrier 2 contains the C-bracket 3 as an essential component, which is designed as a C-shaped welded construction with a U-shaped cross section is trained.
  • the C-claw 3 is about the pivot axis 3.1, which is essentially runs vertically, rotatable. The twisting or pivoting takes place via the Geared motor 12. Also shown in FIG.
  • the C-claw 3 is supported on four castors 14.
  • the castors can additionally with a switchable swivel brake or a directional lock be equipped, in particular when cornering, the pivoting movement of the To be able to block castors 14 about their vertical axis. Then you can regardless of the swivel angle position of the C-claw 3 always the two to Vehicle stem 1 facing castors 14 may be blocked while the two rearmost rollers 14 remain freely pivotable.
  • Figure 3 shows a top view of the vehicle according to the invention with to the right swiveled C-claw 3.
  • the swivel drive for the C-claw 3 which contains the chain sprocket 12.1, which is driven by the motor 12 and which Roll chain 13 sets in motion, the ends of which are attached to the C-claw 3.
  • the C-claw 3 can thus from the position shown on the far right in other positions, e.g. the position shown in Figure 4, completely after be pivoted behind.
  • 9 with the holder is designated, part 1, the Vehicle stem with which the C-claw 3 connects.
  • FIG. 4 shows the vehicle with the C-claw 3 pivoted backwards again the telescope 4, which pushes the load backwards, here drawn in dashed lines, enables.
  • the load rests on the mast truck 5, which the Carries mast 6 on which the fork carriage 7 with the fork tines 8 is located.
  • the load is preferably inside the C-claw 3. This avoids tilting moments.
  • the C-claw 3 is here with two joint bearings 3.2 attached to the vehicle stem 1.
  • the articulated connection shown between vehicle stem 1 and load carrier 2 the latter can also have a rigid Flange connection with the vehicle stem 1 connected (screwed). Then are no longer four castors 14, but only two castors necessary.
  • the Inner diameter and the opening width of the C-claw 3 are determined in that the loading unit to ensure the required floor-level pick-up / delivery can be pushed in and out horizontally without collision through the opening of the C's and does not have to be lifted over the wheel arms of the claw 3.
  • the loading unit Swiveling the C-claw 3 around the pivot axis 3.1 by 90 ° in each case without that the vehicle contour is exceeded by the outer contour of the loading unit.
  • FIG. 5 shows details of the bracket 9.
  • the bracket 9 is on the hinge bearing 3.2 movably connected to the vehicle stem 1.
  • the one here as a welded part trained bracket 9 takes over the leadership with four horizontal rollers 10 the C-claw 3 when pivoting about its vertical axis 3.1.
  • the four vertical Rollers 11 serve to absorb the forces that occur when the center of gravity the loading unit is outside the contact area of the C-claw 3 and thus a Tipping moment works.
  • the two spherical bearings 3.2 are used to connect the bracket the vehicle stem 1 and level unevenness or smaller heels, such as arise when entering and leaving a freight elevator can.
  • FIG. 6 shows an embodiment of the mast pusher 5 according to the invention here from the base frame 5.1, in which the four rollers 5.2 are mounted.
  • the Base frame 5.1 serves to accommodate the lifting mast 6.
  • the mast pusher 5 is horizontally extended and retracted along the inner profile pairs of the telescope 4.
  • Lifting device can use the initial lifting device of a picking stacker become. It consists e.g. from the mast 6, a single-acting Hydraulic cylinder 6.2 and a running over a pair of guide rollers 6.3, simple reeved lifting chain pair 6.1, which the fork carriage 7 with the attached Fork pair 8 carries.
  • FIG. 7 shows the C-claw 3.
  • the C-claw 3 or the C-arm is a C-shaped trained welded construction, which is designed here with a U-shaped cross section. It consists of the upper flange 3.3, the lower flange 3.4 and the two Flanges connecting webs 3.5. At the lower flange 3.4 there are four castors 14 appropriate. 3.1 is the pivot axis.
  • FIGS 8 and 9 show the telescope 4 in its structure and in its Functionality.
  • the telescope 4 for the horizontal extension of the mast pusher 5 consists of two telescopic profile pairs.
  • the outer pair of profiles 4.1 is fixed with the C-claw 3 connected.
  • the inner profile pair 4.2 can with the help of two in outer profile pair 4.1 arranged double-acting hydraulic cylinders 4.3 extend and retract opposite the outer profile.
  • the management of the two profile pairs 4.1, 4.2 is taken over by two pairs of rollers 4.4.
  • There is a pair of rollers 4.4 stored in the outer profile pair 4.1, the other in the inner profile pair 4.2. in the inner profile pair 4.1 runs the mast truck 5, which carries the lifting device 6.
