Definitions

  • the invention relates to a device for manipulating packaged and unpackaged, but essentially dimensionally stable transport goods with a work trolley.
  • Containers, drums, cardboard boxes and similar goods are loaded into larger transport containers, for example containers, the loading space of a truck, rail wagons, ship loading space etc. for transport over long distances. To do this, they have to be manipulated again and again during loading and unloading, which also applies to the picking of the transport goods. If the containers in which the transport goods are grouped are not exactly small and light, this is a very tiring and long-term for workers harmful activity. Although pallets are used in many areas as carriers of the transport goods that can be moved mechanically by forklifts, this help is often not sufficient and practical when it comes to stowing or unloading stowed goods or order picking.
  • a large number of work tools for manipulating palletized goods are known, but these are not suitable for variable use when depalletizing and when palletizing or loading and unloading transport goods of different geometries and different materials.
  • the known working means are generally geared specifically to the goods to be manipulated, for example to the manipulation of bulk goods or packed goods of predetermined uniform packaging sizes.
  • a support element which can be moved horizontally (X, Y) and is variable in length on the work trolley and essentially vertically to and fro at its free end
  • a substantially flat storage element is movably arranged, which is provided with a working arm that can be rotated to the horizontal plane and displaceable at least in the horizontal plane, with a contact element for displacing and / or tilting the transport goods onto or from the storage element essentially at right angles at the free end of the working arm is arranged.
  • the main advantage of the device according to the invention lies in the fact that the tipping moment which inevitably arises when manipulating transport goods on shelves has become manageable, so that the device according to the invention can in principle be assumed to be safe from tipping over.
  • the support element is fastened to the pallet truck via a first stand which is fastened essentially vertically to the pallet truck.
  • a first stand which is fastened essentially vertically to the pallet truck.
  • the support element for changing the length consists of a plurality of support sub-elements which are connected to one another via joints movable in the horizontal plane. This allows the function "change distance" of the device to be manipulated to be manipulated in a simple manner, although It must be pointed out that it is also possible in principle to provide a telescopic length adjustability of the support element, in particular to avoid the protruding geometric parts of the support element at certain length settings.
  • the bearing element is preferably guided in a second stand, which is supported on the ground in a mobile manner and is supported essentially in the vertical direction, during its vertical back and forth movement.
  • the second stand is used to move the mounting element attached or mounted on it in height, i. H. to change the distance to the floor level in order to be able to move the storage element to the height of the goods to be manipulated.
  • the vertical back and forth movement of the bearing element takes place by means of a traction means that can be wound on at least one traction drum, the rotational movement of the traction drum by means of pulling a circularly closed one Pull chain is done.
  • This solution is also advantageous from an ergonomic point of view, since the forces required to carry out the lifting work can be applied with the arm system of the worker by pulling from top to bottom using the body weight.
  • such a configuration enables the worker to have a variable posture, the worker also being able to choose different travel paths depending on the load to be moved, depending on the size of the load to be moved, with a sufficient reduction between the pull drum on the one hand and the wheel, on which the train chain runs, on the other hand is chosen.
  • gravity can also facilitate the lowering movement of the bearing element.
  • the storage element is advantageously provided with a substantially horizontally extending support arm, which in the second Stand is guided in a suitable manner in the vertical direction, held, wherein the bearing element is pivotable about the support arm.
  • the support arm essentially forms the pivot axis of the bearing element.
  • the storage element is advantageously articulated in the region of its incline with a push rod that acts on it laterally, which in the second stand goes back and forth in the vertical direction is movable and slightly pivotable about its horizontal basic position.
  • a horizontal displacement of the push rod thus causes the bearing plane to pivot when the axis of rotation of the bearing element is fixed.
  • the mounting element has an adjustable strut that runs essentially transversely to the mounting plane to form a Tilting edge, wherein the strut is guided in lateral longitudinal slots at angles that laterally limit the mounting plane of the mounting element.
  • the working arm which grips the goods to be manipulated or, in turn, shifts the goods to be transported to a predetermined location, is advantageously arranged above the plane of the bearing element via a rod-shaped spacer element, the height of the spacer element determining the distance of the working arm axis from the plane of the bearing element , is determined by the height of the cargo to be manipulated normally with the device.
  • the storage element on its front edge is designed slightly obliquely in the manner of a dustpan in order to be able to easily pull the goods to be transported onto the storage element by means of the working arm.
  • This wedge shape also supports the intervening pushing of the storage element under transport goods such as sacks or the like.
  • the wedge shape or inclination also facilitates the pushing down of the transport goods onto a packing layer or onto the floor.
  • the working arm In order to be able to position the working arm when moving the storage element, for example to a stack of packaged goods behind the selected packing or transport goods, in order to move it onto the storage element, the working arm is advantageously designed to be telescopically extendable, the angle of rotation of the working arm axis being adjustable by a coupling device.
  • the contact element is moved behind the packing or Transport goods brought to initiate a pulling or a tipping force on the transport goods.
  • the coupling device for locking the axial mobility of the working arm is advantageously a ratchet coupling which can be disengaged against the force of an engagement spring by means of an actuating lever which can be actuated manually by the working person, so that as a result the working arm is pivoted axially and the contact element, after being behind the goods to be transported, that is to be manipulated, has been positioned, is locked in this position.
  • the extension is advantageously effected by means of a band-shaped traction means which can be actuated by hand via a drawbar.
  • the horizontal shortening of the working arm is also advantageously effected by means of a manually operated pull rope.
  • FIG. 1 in which the device 10 according to the invention is shown schematically in a side view.
  • the device 10 essentially comprises a work trolley, which is designed here as a fork-lift truck 11 of commercial design, to which the remaining parts of the device 10 are attached. Basically, however, any other mobile transport device can be used instead of the pallet truck 11 shown here.
  • a first stand 17 unlike in the illustration in FIG. 1, is fastened, which is essentially as high as a second stand 19, which will be discussed in more detail below, cf. also Fig. 2.
  • On the first stand 17 is substantially horizontal, i. H. a variable-length support element 12 is attached in the X, Y plane.
  • the free end 13 of the support element 12 is in turn in the X, Y plane, i.e. H.
  • the horizontal plane is rotatably attached to a second stand 19 extending essentially in the vertical direction Z.
  • An essentially flat bearing element 14 is arranged on the second stand 19, which is suitably supported there in the vertical direction according to the arrow 33 and can be moved back and forth.
  • the push rod 142 which is located in the second stand 19, is also suitable essentially horizontally, ie in the X, Y plane from the stand 19 in the basic position.
  • a support arm 25, which can be moved back and forth in the vertical direction, is also suitably mounted in the second stand 19.
  • Mounted on the support arm 25 is the bearing element 14, on which a working arm 15 is fastened, on which in turn a flat contact element 16 with a wedge-shaped cross section, cf. Fig. 3 is attached.
  • the contact element 16 is arranged essentially at right angles to the working arm axis 150.
  • the support element 12 can consist of a plurality of support sub-elements 120.
  • the supporting sub-elements 120 are connected to one another via joints 121 movable in the horizontal plane X, Y.
  • the second stand 19 is supported on a base 18 by means of a joint which can be rotated about the Z axis and via wheel 191.
  • the second stand 19 can also be formed in two parts, a lower stand part 190 being able to be designed to be folded away via a hinge device 192. This configuration makes it possible to easily compensate for differences in height between a base 18 on which the pallet truck 11 is located and the base on which the second stand 19 stands during the manipulation activity.
  • the rotational movement exerted on the pull drum 20 is effected by pulling a circularly closed pull chain 24, which acts on a corresponding wheel 34. that, suitably reduced, acts on the pull drum, for example, via a toothed belt 35.
  • the lifting or lowering movement of the bearing element 14 is effected by two drums 20, 21 which wind up the traction means 23, so that a corresponding drum can be assigned to each direction of force.
  • the bearing element 14 which has an essentially planar support surface for receiving transport goods, is moved over a substantially horizontal, ie. H. in the X, Y plane extending bracket 25 held.
  • the bearing element 14 can be pivoted around this, which is explained in more detail below.
  • the bearing element 14 has a gap 140 formed on its receiving surface, which is dimensioned such that even goods with an approximately circular cross section, such as filled sacks or barrels, can be securely received on it.
  • the front edge of the bearing element 14 is chamfered in the manner of a dustpan, i. H. Wedge-shaped in cross section in order to make it easier to pick up goods to be transported from the floor or ground 18 or to be able to easily remove the goods to be transported from the receiving surface of the bearing element 14.
  • the bearing element 14 is connected in the region of its incline, ie at an angle that laterally delimits the bearing surface of the bearing element 14, via a hinge connection 143 to the free end of the push rod 142.
  • this connection is shown in dash-dot lines in FIG. 2, since the Fig. 2 does not show the bearing element 14 for reasons of clarity.
  • the push rod 142 which is movable back and forth in the second stand 19 in the vertical direction, can be pivoted slightly about its horizontal basic position, ie out of the X, Y plane.
  • the bearing element 14 has a strut 144 which is essentially transverse to the bearing plane.
  • the strut 144 can be positioned and fixed in a suitable manner in the two upstanding legs of the angles formed laterally and delimiting the working surface of the bearing element 14.
  • the strut 144 forms a tilting edge so that the goods to be transported do not slip away when placed on the tilting edge, since the friction of the tilting edge on the bearing plane is often not sufficient to absorb the horizontal portion of the tilting forces.
  • a spacer element 26, which receives the working arm 15, is formed on the bearing element 14, essentially standing vertically away from the bearing element 14, cf. 3 and 4 in particular.
  • the working arm 15 itself is designed in the form of a telescope.
  • the working arm 15 can be rotated about its working arm axis 150 by at least 180 °, so that the contact element 16 can be moved into a tilted, not shown passive end position.
  • the contact element 16 which is attached to the working arm 15 substantially perpendicular to the working arm axis 150, has a wedge-shaped cross section, which makes it possible in a simple manner that the contact element 16 can get behind the corresponding goods to be manipulated in packing units, even if the individual packaged goods lie close together.
  • the working arm 15 has a coupling device 27, which is designed here in the form of a ratchet coupling.
  • a coupling device 27 which is designed here in the form of a ratchet coupling.
  • the ratchet clutch can be disengaged against the force of an engagement spring 29, which is suitably acted upon by the adjusting lever 28, so that the working arm 15 can be rotated about its working arm axis 150 by the worker according to the desired angle.
  • a reversal of the movement of the actuating lever 28 results in a corresponding engagement of the coupling and fixing the arm in the selected position.
  • the contact element 16 fastened to the working arm 15 can be moved to a suitable location on or in a stack or row of packaged goods in order to get behind the desired transport or packaged goods to be manipulated.
  • the horizontal extension of the working arm 15 takes place via a pull bracket 13. This can be effected by means of a suitably deflected band-shaped pulling means 31.
  • the horizontal shortening of the working arm 15 can also be effected by means of a manually operated pull cable 32.
  • the plane of the bearing element 14 rotates around the articulated connection 143, ie around the front end of the push rod 14, which is held in height by means of a lockable sliding guide in the second stand 19.
  • the goods to be packed or positioned on a stack or the like are carried out in the reverse process.
