Definitions

  • the invention relates to a paper roll transport carriage with a support element for a paper roll and a plurality of special running elements which are intended for rolling in a running rail.
  • the invention also relates to a paper roll transport system which comprises a running rail network in which branch points are formed by fixed crossing elements. Paper roll transport trolleys of the type mentioned at the outset can be guided on novel tracks on this track network.
  • paper rolls weighing up to approximately 1.8 t have to be transported quickly from one place to another.
  • paper rolls are to be transported from a paper roll store to unpacking and gluing station preparation stations. From there, the paper rolls prepared in this way must be transported to the rotary printing press.
  • Waste paper rolls that are to be removed from a roll dispenser of a rotary printing press are often disposed of differently than the new ones Rolls of paper to avoid blocking supply routes. It is also necessary to change the paper roll on the printing presses, even if the paper roll is not yet used, if the paper roll web width changes due to a different newspaper format or an insert to be printed with a different format.
  • a print shop In order to be able to carry in and out the heavy paper rolls or the remaining rolls, a print shop is equipped with an entire rail network in which paper roll transport trolleys, also called “transport dogs", are motor-supported or can be moved manually.
  • the paper roll transport has been carried out with trolleys, in which a support for a paper roll is attached to a drive that consists of several wheels.
  • the entire drive is accommodated in a rail space located below the floor surface.
  • the wheels are guided in a rail that is completely recessed in the floor.
  • This system does not differ fundamentally from a rail system as used in the railroad or other rail-based transport systems.
  • the running wheels have a flat wheel rim section which is guided along a side surface of the rail head of the rail.
  • the rails which are completely embedded in the floor, are only accessible from the outside via the narrowest possible slot.
  • a support element protrudes through the slot and is connected to the paper roll support of the trolley.
  • the entire drive of such a known transport carriage, which consists of the normal side-guided wheels, is housed in the floor.
  • the construction measures required to install such a transport system are very complex and expensive.
  • the ground foundations must be adapted to the planned transportation system. Subsequent installation of such a rail system is only possible under great circumstances, if at all.
  • appropriately deep-seated turntables are necessary at the crossing points of two railways so that a transport carriage can be moved into a rail branch branching off to the side.
  • the turntables are rotatably embedded in the floor, making them very complex and expensive.
  • the effort required to turn such a turntable with a transport trolley thereon and the heavy paper roll is very high.
  • dirt penetrating through the slot into the rail space below the floor is very difficult to remove.
  • DE-U-296 09 589 describes a transport system for feeding paper rolls to a roll changer, an adapter carriage being provided there, but which can only be moved linearly on rollers in a rail.
  • the underlying technical problem underlying the invention is to create a paper roll transport system and a paper roll transport carriage designed for this purpose, in which the disadvantages explained above are largely eliminated.
  • the invention is based on the idea of replacing the previously used castors which can be rotated around a wheel axle by completely new running elements which can be rolled off in several directions for the first time, and correspondingly a new flat one To provide a guide profile to guide the running elements.
  • This makes it possible for the turntables previously required to be replaced by fixed crossing elements, which significantly reduces the installation effort and reduces the costs for the transport system. It also makes it possible for the first time to significantly reduce the installation depth of the running rails and the crossing elements.
  • the fact that the crossing elements do not include any moving parts also increases operational safety.
  • a group comprises two or more running elements, which are each arranged in a row at an even distance apart.
  • the number of running elements in a group is preferably limited to two, since the crossing elements can then be designed more simply; by providing an advantageously existing rotary guide groove, which will be explained later.
  • the underside of the support element is angled upward in cross section Side parts on, or is substantially V-shaped, and the running elements are arranged on the outer edge regions of these side parts. This results in an extremely low overall height of the trolley. This small height is necessary so that a paper roll can be rolled onto such a paper roll carriage with as little effort as possible.
  • a ramp which extends towards the floor and can be rotated about a horizontal axis is advantageously provided at least on one long side of the support element.
  • the ramp preferably has a bearing point at which it can be releasably placed on the trolley and at which the ramp can be rotated about a horizontal axis of rotation.
  • a section of the ramp extends beyond this bearing point. This section can be inserted into a recess in the support element.
  • Such a ramp can be produced very cheaply from sheet steel, for example, and is also extremely robust.
  • this configuration of the ramp holds it in place on a paper roll located on the support element. Because the paper roll is then on the section of the ramp that protruded beyond the storage location.
  • Pushing the trolley on and off with such a centering element is facilitated in that this is spring loaded. Due to the suspension, a centering is achieved when pushed onto a counter element of the centering element on the trolley, but this can be easily solved by overcoming the spring force in one direction, but blocked in the other direction.
  • a rotating cap is very advantageous, which can be pivoted about a horizontal axis of rotation.
  • a centering element a spherical shell directed towards the bottom, which interacts with a bottom-side centering ball section, is very simple and extremely effective. It is of course also possible to interchange the two elements, i.e. the centering element on the trolley is a centering ball section and interacts with a bottom centering shell.
  • a freely rotatable running ball is advantageous as an extremely load-bearing and at the same time having a very low rolling friction. This makes it possible to move the trolley in different directions, as well as rotating it in appropriately pre-shaped guide profiles of the running rails. At the same time, such balls allow an extremely low construction. Even with the high absorption forces, relatively small running balls are sufficient, which for example have a radius of 15 to 25 mm, advantageously 18 to 20 mm. Four such rollers at a distance of about 350 to 450 mm create a tipping-proof, very low-build transport trolley. An extremely robust embodiment of such balls is given by the fact that they are each stored in a shell on a large number of small balls. Such a ball structure is also referred to as a ball roller. The construction of these ball casters enables effortless movement or rotation in any direction, even with heavy loads.
  • ball rollers are known per se for installation in ball roller tables. These enable goods to be moved or rotated on the ball roller tables in any direction.
  • ball rollers from Dr. Tretter, machine elements, Göppingen / Germany also excellently suitable for the present, completely new purpose.
  • the support element comprises an upper and a lower part which can be rotated relative to one another about a vertical axis.
  • a rotation of 180 ° of the paper roll on a transport trolley can be necessary, for example, if the paper roll winding direction was not observed when the paper roll was placed on the transport trolley.
  • a paper roll transport system of the type according to the invention in which paper roll transport carriages according to the invention are guided on flat guide profiles of the running rails forming a rail network, have fixed crossing elements at intersection and branching points with guide grooves formed therein which intersect the guide profiles in the running rails. This means that the guide profiles of the rails in crossing areas are extended by corresponding guide grooves in special crossing elements.
  • a steel track is extremely easy to manufacture. Such a running track is also very robust and can easily be run over by forklifts or the like. Due to the essentially flat guide profile in such a running track, driving over with vehicles of all kinds is not a problem.
  • the guide profile in the running rail has an essentially V-shape, the profile flanks of which enclose an angle adapted to the rolling element rolling therein.
  • This angle is advantageously 90 ° - 170 °, in particular in the case of a ball with a radius of 19 mm, an angle of approximately 140 ° is optimal.
  • a transport carriage centering element is present in the center of the intersecting guide profiles in a crossing element.
  • the trolley driven over it is held immovably, but at the same time allows rotation about the vertical axis. This makes it possible to turn the transport carriage "on the spot" on the crossing element by, for example, 90 ° or more.
  • a simple embodiment of a trolley centering element is provided in that it comprises a spherical section protruding above the top of the crossing element. This protruding ball section can easily be run over by forklifts, for example. A corresponding spherical shell or dome part is then provided as a counterpart on the transport carriage.
  • trolley centering element can be raised and lowered in the crossing element.
  • a trolley centering element is thus completely retractable, so that if the crossing element is not extended, this does not become a "trip hazard" or damage to other vehicles which drive in the region of the transport system.
  • a rotary guide groove is additionally present in the crossing element.
  • This rotary guide groove has a profile cross section which corresponds to the straight guide grooves in the crossing element and describes a circle in plan view which passes through the intersection points of the straight guide grooves located in the crossing element.
  • crossing element is a steel plate.
  • the linear guide grooves and the rotary guide groove are optimally milled into the crossing plate.
  • the milling can lead to the omission of the guide flanks of the guide grooves at the intersection points of the straight guide grooves and the rotary guide groove, so that, optimally, a support element is used, the one Guiding the running elements in the areas in which the guide flanks of the guide grooves are no longer available.
  • the support element has intersecting guide grooves which are aligned according to the straight guide grooves in the intersection plate, but which have a smaller depth and a smaller width.
  • the additional element is underlaid with at least one washer.
  • the height of the additional element is variable, so that it can be adapted to the external environmental conditions.
  • the additional element is a disk which is made of a harder material than the crossing plate.
  • a wear band which advantageously consists of a steel sheet, to the running profile on the essentially flat or V-shaped guide profiles of the running rails.
  • the wear band is glued to the running rail by means of double-sided adhesive tape.
  • rails of the paper roll transport system according to the invention can also be laid in a curve.
  • the guide profile on the outside of the curve has the same cross section as a guide profile of a straight section of a running rail.
  • the inner guide profile on the other hand is flat due to the given geometry.
  • a first exemplary embodiment of a paper roll transport carriage 1 according to the invention is explained below with reference to FIGS. 1 to 4.

  • the basic structure of the ramp part 11 can be seen in particular from FIG. 4.
  • the ramp part 11 is basically plate-shaped, but has a ramp section 11a on a front section, from which two bearing parts 12 protrude laterally at an angle of approximately 90 °.
