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 paper roll transport carriage 1 comprises a V-shaped support element 2 which has two support surfaces 22 which are inclined and form an obtuse angle.
- the undersides 21 of the support element 2 are also V-shaped (see in particular Fig. 2).
- Two running elements 3 are attached to the outer edge regions of the support element 2, ie to those regions which are the most distant from the floor.
- the running elements 3 are so-called heavy duty rollers or ball rollers, which comprise running balls 4.
- the running balls 4 are held in the running element 3 in a shell freely rotatable in all directions on a large number of small balls.
- a spherical section of the Balls 4 protrude from the running elements 3, so that overall the trolley 1 can be moved on the rollers 4 in guide profiles to be explained.
- stiffening tubes 8 are welded on the sides of the edge regions.
- recesses 6 are also provided in the middle between two running elements 3. On the underside, the recesses 6 are closed by stop plates 7.
- a centering device 5 is present in the center between the four running elements 3 and, in this exemplary embodiment, consists of a rotating spherical cap 37, as will be explained in more detail below with reference to FIG. 7.
- a ramp part 11 can be attached to a recess 6 of the support element 2, with the aid of which a paper roll can be rolled up and down laterally onto the paper roll transport carriage 1.
- 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 °.
- the bearing parts 12 serve as a rotary bearing when the ramp part 11 is placed on the stiffening rod 8.
- further bearing parts 12 are further located on the outside, which are supported on support rods 8a, which are welded to the underside of the support element 2 under associated recesses.
- the ramp part 11 is provided with an inclined surface 13 for resting on the floor.
- FIGS. 5 and 6 A second embodiment of a paper roll transport carriage 201 according to the invention is explained with reference to FIGS. 5 and 6.
- This embodiment of the transport carriage 201 basically has the same structure as the first embodiment.
- the support element 202 is formed in two parts here.
- the support elements here consist of bent steel sheets that are welded to an upper part 206, which is a disk in plan view.
- the two support elements 202 in turn form a V-shaped or trough-shaped depression for the secure mounting of a paper roll 50, as shown in FIG. 6.
- the upper part 206 is rotatably arranged on a lower part 207 via axial roller bearings 208.
- running elements 203 are fastened to the corner regions, each with a running ball 204.
- These running elements 203 correspond to the running elements 3 of the first embodiment. This means that these are so-called heavy-duty rollers, the running balls of which are mounted in a shell, advantageously for reducing the friction with the interposition of a large number of small balls.
- the lower part 207 has a through hole, through which a centering device 205 extends, which is attached to the upper part 206.
- This centering device is provided on the end face towards the bottom with a spherical cutout 205a, so that a spherical section can be inserted laterally.

- a centering device 5 is shown in more detail in FIG. 7, which can be used both in a transport carriage 1 of the first embodiment and in a transport carriage 201 according to the second embodiment.
- This centering device 5 comprises a rotating cap 37 which can be pivoted about an axis 36. However, the pivoting movement of the rotary cap 37 is limited in one direction by a stop 38. A spring prestressing force is applied in the other pivoting direction, so that the spherical section milling on the end face of the rotating cap 37 can easily snap onto a corresponding counterpart 35 on an intersection plate 30.
- FIG. 8 shows a schematic rail plan for a paper roll transport system according to the invention, in which transport carriages of the aforementioned type can be moved automatically by hand or on sections by drag conveyors.

- disks 70 are used, each of which has a cross profile milled therein with a trough-shaped or radius-shaped cross section. This also ensures that a roller is guided in the critical areas of the crossing points.
- the trough-shaped guide profiles 71 in the disk 70 extend in the extension of the guide grooves 32 of an intersection plate 30.
- the disks 70 are underlaid with washers 76. If the crossing plates 30, which are made of a softer material than the disks 70, are used for a longer period of time, the guide grooves 32 will wear out accordingly. To compensate for this wear, one or more washers 75 are removed so that the disks 70 are adapted to the actual height of the guide grooves 32 can.
- FIG. 9 shows a schematic cross-sectional view through a running rail 60, in which a running ball 4 rolls.

Abstract
Description
Die Erfindung betrifft einen Papierrollen-Transportwagen mit einem Auflageelement für eine Papierrolle und mehreren speziellen Laufelementen, die zum Abrollen in einer Laufschiene bestimmt sind.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.
Außerdem betrifft die Erfindung ein Papierrollen-Transportsystem, das ein Laufschienennetz umfaßt, in dem Abzweigungsstellen durch feststehende Kreuzungselemente gebildet sind. Papierrollen-Transportwagen der eingangs genannten Art sind auf diesem Laufschienennetz auf neuartigen Laufschienen geführt verfahrbar.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.
In Druckereien, insbesondere Zeitungsdruckereien, müssen bis zu ungefähr 1,8 t schwere Papierrollen schnell von einem Ort zum anderen transportiert werden. So sind Papierrollen beispielsweise von einem Papierrollenlager zu Auspack- und Klebestellenvorbereitungs-Stationen zu transportieren. Von dort wiederum müssen die so vorbereiteten Papierrollen zu den Rotationsdruckmaschinen transportiert werden. Restpapierrollen, die aus einem Rollenspender einer Rotationsdruckmaschine zu entfernen sind, werden dabei oftmals auf anderen Wegen entsorgt als die neuen Papierrollen, um eine Blockierung der Versorgungswege zu vermeiden. Außerdem ist ein Papierrollenwechsel an den Druckmaschinen auch bei noch nicht verbrauchter Papierrolle notwendig, wenn aufgrund eines anderen Zeitungsformats oder einer zu druckenden Beilage mit anderem Format die Papierrollenbahnbreite wechselt.In printers, especially newspaper printers, paper rolls weighing up to approximately 1.8 t have to be transported quickly from one place to another. For example, 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.
Um den Zu- und Abtransport der schweren Papierrollen bzw. der Restrollen durchführen zu können, ist eine Druckerei mit einem ganzen Schienennetz ausgestattet, in dem Papierrollen-Transportwagen, auch "Transporthund" genannt, motorisch unterstützt oder manuell geschoben verfahrbar sind.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.
Bisher erfolgt der Papierrollen-Transport mit Transportwagen, bei denen eine Auflage für eine Papierrolle auf einem Laufwerk befestigt ist, das aus mehreren Laufrädern besteht. Das gesamte Laufwerk ist bei dem bekannten System in einem unterhalb der Bodenoberfläche befindlichen Schienenraum untergebracht. Die Laufräder sind hierin in einer im Boden vollständig versenkten Schiene geführt. Dieses System unterscheidet sich grundsätzlich nicht von einem Schienensystem, wie es bei der Eisenbahn oder anderen schienengebundenen Transportsystemen zum Einsatz kommt. Zur Seitenführung weisen die Laufräder einen flachen Radkranzabschnitt auf, der an einer Seitenfläche des Schienenkopfes der Schiene entlanggeführt wird.So far, 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. In the known system, 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. For lateral guidance, the running wheels have a flat wheel rim section which is guided along a side surface of the rail head of the rail.
Die vollständig im Boden eingebetteten Schienen sind lediglich über einen möglichst schmalen Schlitz von außen zugänglich. Durch den Schlitz ragt ein Stützelement heraus, das mit der Papierrollenauflage des Transportwagens verbunden ist. Das gesamte Laufwerk eines solchen bekannten Transportwagens, das aus dem normalen seitengeführten Laufrädern besteht, ist im Boden untergebracht.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.
Dadurch, daß die Schiene das gesamte Laufwerk aufnehmen muß, sind die erforderlichen Baumaßnahmen zum Einbau eines derartigen Transportsystem sehr aufwendig und teuer. Überdies müssen die Bodenfundamente dem geplanten Transportsystem angepaßt sein. Damit ist ein nachträglicher Einbau eines derartigen Schienensystems, wenn überhaupt, nur unter großen Umständen möglich. Darüber hinaus sind entsprechend tiefbauende Drehscheiben an Kreuzungspunkten zweier Schienenwege notwendig, damit ein Transportwagen in einen seitlich abzweigenden Schienenstrang verfahren werden kann. Die Drehscheiben sind hierzu drehbar im Boden eingelassen, damit sehr aufwendig und teuer. Außerdem ist der notwendige Kraftaufwand zum Drehen einer derartigen Drehscheibe mit darauf befindlichem Transportwagen und der schweren Papierrolle sehr hoch. Schließlich ist zu bemerken, daß durch den Schlitz in den unterhalb des Bodens liegenden Schienenraum eindringender Schmutz nur sehr schwer wieder zu entfernen ist.Because the rail has to accommodate the entire drive, the construction measures required to install such a transport system are very complex and expensive. In addition, 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. In addition, 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. In addition, the effort required to turn such a turntable with a transport trolley thereon and the heavy paper roll is very high. Finally, it should be noted that dirt penetrating through the slot into the rail space below the floor is very difficult to remove.
Ein Transportsystem, wie es zuvor erläutert wurde, ist von der Firma "von Roll Maschinen- und Fördertechnik AG" bekannt. So wird ein derartiges System unter dem Markennamen "Mecaroll-System" vertrieben.A transport system, as previously explained, is known from the company "von Roll Maschinen- und Fördertechnik AG". Such a system is sold under the brand name "Mecaroll system".
Aus der DE-U-297 00 874 ist ein gattungsgemäßes schienengeführtes Rollen-Transportsystem bekannt, bei welchem an dem Transportwagen Paare von rechtwinklig zueinander angeordneten Laufrollen vorgesehen sind, die jeweils nur in einer Richtung vor- und rückwärts abrollbar sind.From DE-U-297 00 874 a generic rail-guided roller transport system is known, in which pairs of rollers arranged at right angles to one another are provided on the transport carriage, which can only be rolled back and forth in one direction.
In der DE-U-296 09 589 ist ein Transportsystem zur Zuführung von Papierrollen zu einem Rollenwechsler beschrieben, wobei dort ein Adapterwagen vorgesehen ist, der jedoch nur linear auf Laufrollen in einer Schiene verfahrbar ist.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.
Das der Erfindung zugrundeliegende übergeordnete technische Problem besteht darin, ein Papierrollen-Transportsystem und einen hierfür konzipierten Papierrollen-Tranportwagen zu schaffen, bei denen die zuvor erläuterten Nachteile weitgehend beseitigt sind.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.
Dieses technische Probleme wird durch einen Papierrollen-Transportwagen mit den Merkmalen des Anspruchs 1 bzw. durch ein Papierrollen-Transportsystem mit den Merkmalen des Anspruchs 16 gelöst.This technical problem is solved by a paper roll transport trolley with the features of claim 1 or by a paper roll transport system with the features of claim 16.
Der Erfindung liegt der Gedanke zugrunde, die bisher verwendeten, um eine Radachse drehbaren Laufrollen durch völlig neue Laufelemente zu ersetzen, die erstmals in mehrere Richtungen abrollbar sind, und entsprechend ein neues flaches Führungsprofil zur Führung der Laufelemente vorzusehen. Dadurch ist es möglich, daß die bisher erforderlichen Drehscheiben durch feststehende Kreuzungselemente ersetzt werden können, was den Einbauaufwand wesentlich verringert und die Kosten für das Transportsystem reduziert. Außerdem ist es damit erstmals möglich, die Einbautiefe der Laufschienen und der Kreuzungselemente signifikant zu reduzieren. Dadurch, daß die Kreuzungselemente keine beweglichen Teile umfassen, ist auch die Betriebssicherheit erhöht.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.
Im Gegensatz zu den bisherigen Transportwagen, bei denen das Laufwerk mit den einzelnen Laufrädern möglichst mittig angeordnet wurde, um nur einen Zugangsschlitz zu den Schienen bereitstellen zu müssen, ist es nun vorteilhaft, wenn Gruppen von Laufelementen an zwei gegenüberliegenden äußeren Randbereichen des Auflageelementes angeordnet sind. Dadurch ergibt sich eine größere Kippsicherheit des Papierrollen-Transportwagens. Bei den bisherigen Schienen mußten zur Erzielung einer ausreichenden Kippsicherheit der Wagen besondere Maßnahmen im Schienenraum getroffen werden. Dadurch erhöhte sich auch der Rollwiderstand beim Verfahren der Transportwagen, was einen erhöhten Kraftaufwand beim Schieben durch eine Bedienperson der wieso schon schweren Papierrollen erforderte.In contrast to the previous transport trolleys, in which the drive with the individual running wheels was arranged as centrally as possible in order to only have to provide an access slot to the rails, it is now advantageous if groups of running elements are arranged on two opposite outer edge regions of the support element. This results in greater security against tipping of the paper roll transport trolley. In the case of the previous rails, special measures had to be taken in the rail space in order to achieve sufficient tipping safety for the wagons. This also increased the rolling resistance when moving the trolleys, which required an increased effort when pushing by an operator of the already heavy paper rolls.
Je nach Tragfähigkeit der in mehreren Richtungen abrollbaren Laufelemente umfaßt eine Gruppe zwei oder mehr Laufelemente, die jeweils gleichmäßig beabstandet in einer Reihe angeordnet sind. Vorzugsweise wird die Zahl der Laufelemente einer Gruppe auf zwei begrenzt sein, da dann die Kreuzungselemente einfacher ausgestaltet werden können; indem dadurch eine vorteilhafterweise vorhandene Dreh-Führungsnut, die später noch erläutert wird, vorzusehen ist.Depending on the load-bearing capacity of the running elements that can be rolled off in several directions, 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.
Nach einer bevorzugten Ausführungsform weist die Unterseite des Auflageelementes im Querschnitt nach oben abgewinkelte Seitenteile auf, bzw. ist im wesentlichen V-förmig, und an den äußeren Randbereichen dieser Seitenteile sind die Laufelemente angeordnet. Dadurch ergibt sich eine äußerst geringe Bauhöhe des Transportwagens. Diese geringe Bauhöhe ist notwendig, damit eine Papierrolle mit möglichst geringem Kraftaufwand auf einen derartigen Papierrollenwagen gerollt werden kann.According to a preferred embodiment, 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.
Um das Aufrollen der Papierrolle auf das Auflageelement des Transportwagens zu erleichtern, ist vorteilhafterweise zumindest auf einer Längsseite des Auflageelementes eine sich zum Boden hin erstreckende, um eine horizontale Achse drehbare Rampe vorgesehen.In order to facilitate the rolling up of the paper roll onto the support element of the transport carriage, 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.
Bevorzugtermaßen besitzt die Rampe eine Lagerstelle, an der sie am Transportwagen lösbar auflegbar ist und an der sich die Rampe um eine horizontale Drehachse drehen läßt. Außerdem ragt ein Teilstück der Rampe über diese Lagerstelle hinaus. Dieses Teilstück ist in eine Ausnehmung in dem Auflageelement einfügbar. Eine derartige Rampe ist beispielsweise aus Stahlblech sehr kostengünstig herstellbar und überdies äußerst robust. Ferner wird durch diese Ausgestaltung der Rampe diese bei einer auf dem Auflageelement befindlichen Papierrolle festgehalten. Denn die Papierrolle befindet sich dann auf dem Teilstück der Rampe, das über die Lagerstelle hinausragte.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. In addition, 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. Furthermore, 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.
Um an einer Kreuzungsstelle zweier Schienenwege das seitliche Verfahren des Transportwagens zu erleichtern bzw. dessen Zentrierung auf die seitlichen Laufschienen wie auch dessen Drehung zu erleichtern, ist ein Zentrierelement im Mittelbereich des Auflageelementes vorhanden, mit dem der Transportwagen unverschieblich fixierbar ist, gleichzeitig aber um seine Hochachse verdrehbar ist.In order to facilitate the lateral movement of the transport carriage at a crossing point of two rail tracks or to facilitate its centering on the lateral running rails as well as its rotation, there is a centering element in the central region of the support element, with which the transport carriage can be fixed immovably, but at the same time around its vertical axis is rotatable.
Das Auf- und Wegschieben des Transportwagens mit einem solchen Zentrierelement wird dadurch erleichtert, daß dieses gefedert gelagert ist. Durch die Federung wird beim Aufschieben auf ein Gegenelement des Zentrierelementes am Transportwagen eine Zentrierung erzielt, die aber durch Überwindung der Federkraft in eine Richtung sehr leicht lösbar ist, in die andere Richtung aber blockiert.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.
Hierzu ist beispielsweise eine Drehkalotte sehr vorteilhaft, die um eine horizontale Drehachse verschwenkbar ist. Sehr einfach und äußerst wirksam ist als Zentrierelement eine zum Boden hin gerichtete Kugelschale, die mit einem bodenseitigen Zentrierkugelabschnitt zusammenwirkt. Es natürlich auch möglich, die zwei Elemente miteinander zu vertauschen, d.h. das Zentrierelement am Transportwagen ist ein Zentrierkugelabschnitt und wirkt mit einer bodenseitigen Zentrierschale zusammen.For this purpose, for example, a rotating cap is very advantageous, which can be pivoted about a horizontal axis of rotation. As 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.
Als äußerst tragfähiges und gleichzeitig eine sehr geringe Rollreibung aufweisendes Laufelement ist eine frei drehbare Laufkugel vorteilhaft. Damit ist ein Verfahren des Transportwagens in unterschiedliche Richtungen möglich, wie auch ein Drehen desselben in entsprechend vorgeformten Führungsprofilen der Laufschienen. Gleichzeitig ermöglichen derartige Laufkugeln eine äußerst niedrige Bauweise. Auch bei den hohen Aufnahmekräften sind relativ kleine Laufkugeln ausreichend, die beispielsweise einen Radius von 15 bis 25 mm besitzen, vorteilhafterweise 18 bis 20 mm. Vier derartige Laufrollen in einem Abstand von etwa 350 bis 450 mm schaffen einen kippsicheren, sehr niedrig bauenden Transportwagen. Eine äußerst robuste Ausführungsform derartiger Laufkugeln ist dadurch gegeben, daß diese jeweils in einer Schale auf einer Vielzahl von kleinen Kugeln gelagert sind. Ein derartiger Kugelaufbau wird auch als Kugelrolle bezeichnet. Die Konstruktion dieser Kugelrollen ermöglicht auch bei schweren Lasten ein müheloses Verschieben oder Drehen in beliebige Richtungen.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.
Derartige Kugelrollen sind an sich zum Einbau in Kugelrollen-Tische bekannt. Diese ermöglichen das Verschieben oder Drehen von Fördergut auf den Kugelrollentischen in jeder Richtung. Beispielsweise sind Kugelrollen der Firme Dr. Tretter, Maschinenelemente, Göppingen/Deutschland auch für den vorliegenden, völlig neuen Einsatzzweck hervorragend geeignet.Such 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. For example, ball rollers from Dr. Tretter, machine elements, Göppingen / Germany also excellently suitable for the present, completely new purpose.
Um ohne Drehung des gesamten Transportwagens eine Drehung der darauf befindlichen Papierrolle zu ermöglichen, ist es vorteilhaft, daß das Auflageelement ein Ober- und ein Unterteil umfaßt, die um eine Hochachse gegeneinander verdrehbar sind. Eine Drehung um 180° der Papierrolle auf einem Transportwagen kann beispielsweise notwendig sein, wenn die Papierrollenaufwickelrichtung beim Auflegen der Papierrolle auf den Transportwagen nicht beachtet wurde.In order to enable the paper roll located thereon to rotate without rotating the entire transport carriage, it is advantageous that 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.
Ein PapierrollenTransportsystem der erfindungsgemäßen Art, in dem erfindungsgemäße Papierrollen-Transportwagen auf flachen Führungsprofilen der ein Schienennetz bildenden Laufschienen geführt werden, weisen an Kreuzungs- und Abzweigungsstellen feste Kreuzungselemente mit darin ausgebildeten, den Führungsprofilen in den Laufschienen entsprechenden Führungsnuten auf, die einander schneiden. Das heißt, daß die Führungsprofile der Laufschienen in Kreuzungsbereichen durch entsprechende Führungsnuten in speziellen Kreuzungselementen verlängert sind.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.
Es ist zum einen denkbar, zwei zueinander parallel verlaufende, flache Führungsprofile in einer Laufschiene vorzusehen. Zum anderen können aber auch zwei voneinander beabstandete Laufschienen vorgesehen werden, die jeweils ein flaches Führungsprofil besitzen. Im ersteren Fall muß die Laufschiene bzw. der Abstand der Führungsprofile in einer solchen Laufschiene der Breite eines Papierrollen-Transportwagens entsprechen. Demzufolge sind derartige Laufschienen relativ breit auszuführen, was beim Anbau möglicherweise aufwendiger sein kann, jedoch die Zahl der einzubauenden Laufschienen verringert. Im zweiten Fall muß nur jeweils der Breite der Laufschiene entsprechend der Boden vorbereitet werden.On the one hand, it is conceivable to provide two flat guide profiles running parallel to one another in a running rail. On the other hand, two spaced-apart running rails can also be provided, each of which has a flat guide profile. In the former case, the running rail or the distance between the guide profiles in such a running rail must correspond to the width of a paper roll transport carriage. As a result, such rails are relatively wide, what when mounting may be more complex, but the number of rails to be installed is reduced. In the second case, the floor only has to be prepared according to the width of the running rail.
Äußerst einfach herzustellen ist eine Laufschiene aus Stahl. Eine derartige Laufschiene ist auch sehr robust und kann von Gabelstaplern oder dergleichen problemlos überfahren werden. Aufgrund des im wesentlichen flachen Führungsprofils in einer derartigen Laufschiene ist das Überfahren mit Fahrzeugen aller Art kein Problem.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.
Eine optimale Führung eines Papierrollen-Transportwagens mit Laufkugeln ist dadurch gegeben, daß das Führungsprofil in der Laufschiene eine im wesentlichen V-Form besitzt, deren Profilflanken einen dem darin abrollenden Laufelement angepaßten Winkel einschließen. Vorteilhafterweise beträgt dieser Winkel 90° - 170°, insbesondere bei einer Laufkugel von einem Radius mit 19 mm ist ein Winkel von ungefähr 140° optimal. Bei einem derartigen Führungsprofil ist die Rollreibung zwischen Schiene und Laufkugel minimiert, gleichzeitig aber eine notwendige Führung der Laufkugel gegeben.Optimal guidance of a paper roll transport carriage with running balls is provided in that 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. With such a guide profile, the rolling friction between the rail and the running ball is minimized, but at the same time there is a necessary guiding of the running ball.
Damit ein Papierrollen-Transportwagen auf einem Kreuzungselement in einen Seitenschienenstrang überführt werden kann, ist es optimal, wenn im Mittelpunkt der sich kreuzenden Führungsprofile in einem Kreuzungselement ein Transportwagen-Zentrierelement vorhanden ist. Mit einem solchen Transportwagen-Zentrierelement wird der darübergefahrene Transportwagen unverschieblich festgehalten, jedoch gleichzeitig eine Drehung um die Hochachse zugelassen. Damit ist dann ein Drehen des Transportwagens "auf der Stelle" auf dem Kreuzungselement um beispielsweise 90° oder mehr möglich.So that a paper roll transport carriage on a crossing element can be transferred into a side rail section, it is optimal if a transport carriage centering element is present in the center of the intersecting guide profiles in a crossing element. With such a trolley centering 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.
Eine einfache Ausgestaltung eines Transportwagen-Zentrierelementes ist dadurch gegeben, daß dieses einen über die Oberseite des Kreuzungselementes herausstehenden Kugelabschnitt umfaßt. Dieser herausstehende Kugelabschnitt ist ohne weiteres von beispielsweise Gabelstaplern zu überfahren. Als Gegenstück ist dann am Transportwagen ein entsprechendes Kugelschalen- oder Kalottenteil vorgesehen.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.
Denkbar ist jedoch auch, daß das Transportwagen-Zentrierelement in dem Kreuzungselement anheb- und absenkbar angebracht ist. Damit ist ein Transportwagen-Zentrierelement völlig versenkbar, so daß bei nicht ausgefahrenem Kreuzungselement dieses nicht zur "Stolperfalle" wird oder eine Beschädigung von anderen Fahrzeugen, die in dem Bereich des Transportsystem fahren, herbeiführt.However, it is also conceivable that the 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.
Damit ein Papierrollen-Transportwagen problemlos auf dem Kreuzungselement drehen kann, ist es vorteilhaft, daß zusätzlich eine Dreh-Führungsnut in dem Kreuzungselement vorhanden ist. Diese Dreh-Führungsnut besitzt einen Profilquerschnitt, der den geradlinigen Führungsnuten in dem Kreuzungselement entspricht und beschreibt in der Draufsicht einen Kreis, der durch die Schnittpunkte der sich in dem Kreuzungselement befindlichen geradlinigen Führungsnuten geht.So that a paper roll transport trolley can easily rotate on the crossing element, it is advantageous that 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.
Eine Ausführungsform, bei der das Kreuzungselement eine Stahlplatte ist, ist äußerst robust und auch einfach herzustellen.An embodiment in which the crossing element is a steel plate is extremely robust and also easy to manufacture.
Optimalerweise sind die geradlinigen Führungsnuten und die Drehführungsnut in die Kreuzungsplatte eingefräst.The linear guide grooves and the rotary guide groove are optimally milled into the crossing plate.
Durch die Einfräsung kann es an den Schnittpunkten der geradlinigen Führungsnuten und der Drehführungsnut zum Wegfall der Führungsflanken der Führungsnuten kommen, so daß optimalerweise ein Stützelement eingesetzt wird, das eine Führung der Laufelemente in den Bereichen, in dem die Führungsflanken der Führungsnuten nicht mehr vorhanden sind, ermöglicht. Hierfür ist es vorteilhaft, daß das Stützelement sich kreuzende Führungsrillen aufweist, die gemäß den geradlinigen Führungsnuten in der Kreuzungsplatte ausgerichtet sind, aber eine geringere Tiefe und geringere Breite aufweisen.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. For this purpose, it is advantageous that 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.
Zum Ausgleich einer möglichen Höhenveränderung der Führungsnuten in den Kreuzungsplatten durch Verschleiß ist das Zusatzelement mit zumindest einer Unterlegscheibe unterlegt. Durch Wegnahme oder Hinzufügung der Unterlegscheiben ist das Zusatzelement in der Höhe veränderlich, so daß es jeweils den äußeren Umgebungsbedingungen anpaßbar ist. Optimalerweise ist das Zusatzelement eine Scheibe, die aus einem härteren Material besteht als die Kreuzungsplatte.To compensate for a possible change in height of the guide grooves in the crossing plates due to wear, the additional element is underlaid with at least one washer. By removing or adding the washers, the height of the additional element is variable, so that it can be adapted to the external environmental conditions. Optimally, the additional element is a disk which is made of a harder material than the crossing plate.
Um die durch Verschleiß an den Schienen anfallenden Reparaturarbeiten zu vereinfachen, ist es besonders vorteilhaft, auf den im wesentlichen flachen bzw. V-förmigen Führungsprofilen der Laufschienen ein dem Laufprofil angepaßtes Verschleißband, das vorteilhafterweise aus einem Stahlblech besteht, aufzubringen. Bei einer sehr vorteilhaften Ausführungsform ist vorgesehen, daß das Verschleißband mittels einem doppelseitigen Klebeband auf der Laufschiene aufgeklebt ist.In order to simplify the repair work due to wear on the rails, it is particularly advantageous to apply 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. In a very advantageous embodiment it is provided that the wear band is glued to the running rail by means of double-sided adhesive tape.
Schließlich ist noch hervorzuheben, daß Laufschienen des erfindungsgemäßen Papierrollen-Transportsystems auch kurvenförmig verlegbar sind. In diesem Fall weist das kurvenäußere Führungsprofil den gleichen Querschnitt auf wie ein Führungsprofil eines geraden Teilstücks einer Laufschiene. Das kurveninnnere Führungsprofil hingegen ist aufgrund der gegebenen Geometrie eben ausgebildet.Finally, it should be emphasized that rails of the paper roll transport system according to the invention can also be laid in a curve. In this case, 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.

Ein erstes Ausführungsbeispiel eines erfindungsgemäßen Papierrollen-Transportwagens 1 wird nachfolgend anhand der Figuren 1 bis 4 erläutert.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.
Der Papierrollen-Transportwagen 1 umfaßt ein V-förmiges Auflageelement 2, das zwei Auflageflächen 22 besitzt, die geneigt sind und einen stumpfen Winkel einschließen. Die Unterseiten 21 des Auflageelementes 2 sind ebenfalls V-förmig ausgebildet (siehe insbesondere Fig. 2).The paper roll transport carriage 1 comprises a V-shaped support element 2 which has two support surfaces 22 which are inclined and form an obtuse angle. The undersides 21 of the support element 2 are also V-shaped (see in particular Fig. 2).
An den äußeren Randbereichen des Auflageelementes 2, d.h. an denjenigen Bereichen, die gegenüber dem Boden am weitesten beabstandet sind, sind jeweils zwei Laufelemente 3 angebracht. Die Laufelemente 3 sind sogenannte Schwerlastrollen oder Kugelrollen, die Laufkugeln 4 umfassen. Die Laufkugeln 4 sind dabei in dem Laufelement 3 in einer Schale frei drehbar in allen Richtungen auf einer Vielzahl von kleinen Kugeln gelagert gehalten. Ein Kugelabschnitt der Laufkugeln 4 steht aus den Laufelementen 3 vor, so daß insgesamt der Transportwagen 1 auf den Laufrollen 4 in noch zu erläuternden Führungsprofilen verfahren werden kann.Two running elements 3 are attached to the outer edge regions of the support element 2, ie to those regions which are the most distant from the floor. The running elements 3 are so-called heavy duty rollers or ball rollers, which comprise running balls 4. The running balls 4 are held in the running element 3 in a shell freely rotatable in all directions on a large number of small balls. A spherical section of the Balls 4 protrude from the running elements 3, so that overall the trolley 1 can be moved on the rollers 4 in guide profiles to be explained.
Zur Aussteifung des Auflageelementes 2 sind-Versteifuhgsrohre 8 seitlich der Randbereiche angeschweißt. An den Seitenflächen des Auflageelementes sind zudem Ausnehmungen 6 jeweils mittig zwischen zwei Laufelementen 3 vorhanden. Auf der Unterseite sind die Ausnehmungen 6 durch Anschlagplatten 7 abgeschlossen.To stiffen the support element 2, stiffening tubes 8 are welded on the sides of the edge regions. On the side surfaces of the support element, recesses 6 are also provided in the middle between two running elements 3. On the underside, the recesses 6 are closed by stop plates 7.
Mittig zwischen den vier Laufelementen 3 ist eine Zentriereinrichtung 5 vorhanden, die bei diesem Ausführungsbeispiel aus einer Drehkalotte 37 besteht, wie sie im einzelnen noch anhand der Fig. 7 nachfolgend erläutert wird.A centering device 5 is present in the center between the four running elements 3 and, in this exemplary embodiment, consists of a rotating spherical cap 37, as will be explained in more detail below with reference to FIG. 7.
Wie es aus der Fig. 3 ersichtlich ist, kann an eine Ausnehmung 6 des Auflageelementes 2 ein Rampenteil 11 angesetzt werden, mit dessen Hilfe eine Papierrolle seitlich auf den Papierrollen-Transportwagen 1 auf- und herabgerollt werden kann. Der grundsätzliche Aufbau des Rampenteils 11 ist insbesondere aus der Fig. 4 erkennbar. Das Rampenteil 11 ist grundsätzlich plattenförmig, besitzt jedoch an einem vorderen Abschnitt einen Rampenvorbau 11a, von dem seitlich zwei Lagerteile 12 um etwa 90° abgewinkelt vorstehen. Die Lagerteile 12 dienen als Drehlager beim Aufsetzen des Rampenteils 11 auf die Aussteifungsstange 8. Bei dieser Ausführungsform sind weitere Lagerteile 12 weiter seitlich außenliegend vorhanden, die sich auf Abstützstangen 8a abstützen, die auf der Unterseite des Auflageelementes 2 unter zugehörigen Ausnehmungen angeschweißt sind. Zur Auflage auf dem Boden ist das Rampenteil 11 mit einer Schrägfläche 13 versehen.As can be seen from FIG. 3, a ramp part 11 can be attached to a recess 6 of the support element 2, with the aid of which a paper roll can be rolled up and down laterally onto the paper roll transport carriage 1. 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 °. The bearing parts 12 serve as a rotary bearing when the ramp part 11 is placed on the stiffening rod 8. In this embodiment, further bearing parts 12 are further located on the outside, which are supported on support rods 8a, which are welded to the underside of the support element 2 under associated recesses. The ramp part 11 is provided with an inclined surface 13 for resting on the floor.
Eine zweite Ausführungsform eines erfindungsgemäßen Papierrollen-Transportwagens 201 wird anhand der Figuren 5 und 6 erläutert. Diese Ausführungsform des Transportwagens 201 besitzt grundsätzlich den gleichen Aufbau wie die erste Ausführungsform. Im Gegensatz zur ersten Ausführungsform ist jedoch hier das Auflageelement 202 zweiteilig ausgebildet. Die Auflageelemente bestehen hier aus gebogenen Stahlblechen, die an ein Oberteil 206, das in der Draufsicht eine Scheibe ist, angeschweißt sind. Die zwei Auflageelemente 202 bilden wiederum eine V-förmige oder muldenförmige Vertiefung zur sicheren Lagerung einer Papierrolle 50, wie es in der Fig. 6 gezeigt ist. Das Oberteil 206 ist auf einem Unterteil 207 über Axialwälzlager 208 drehbar angeordnet. An dem Unterteil 207, das hier eine quadratische Platte ist, sind an den Eckbereichen Laufelemente 203 mit jeweils einer Laufkugel 204 befestigt. Diese Laufelemente 203 entsprechen den Laufelementen 3 der ersten Ausführungsform. Das heißt, es handelt sich hier um sogenannte Schwerlastrollen, deren Laufkugeln in einer Schale gelagert sind, vorteilhafterweise zur Reduzierung der Reibung unter Zwischenschaltung einer Vielzahl von kleinen Kugeln.A second embodiment of a paper roll transport carriage 201 according to the invention is explained with reference to FIGS. 5 and 6. This embodiment of the transport carriage 201 basically has the same structure as the first embodiment. In contrast to the first embodiment, however, the support element 202 is formed in two parts here. The support elements here consist of bent steel sheets that are welded to an upper part 206, which is a disk in plan view. The two support elements 202 in turn form a V-shaped or trough-shaped depression for the secure mounting of a paper roll 50, as shown in FIG. 6. The upper part 206 is rotatably arranged on a lower part 207 via axial roller bearings 208. On the lower part 207, which is a square plate here, running elements 203 are fastened to the corner regions, each with a running ball 204. These running elements 203 correspond to the running elements 3 of the first embodiment. This means that these are so-called heavy-duty rollers, the running balls of which are mounted in a shell, advantageously for reducing the friction with the interposition of a large number of small balls.
Im Mittelbereich des Transportwagens 201 weist das Unterteil 207 eine Durchgangsbohrung auf, durch das sich eine Zentriereinrichtung 205 erstreckt, die am Oberteil 206 angebracht ist.In the central region of the transport carriage 201, the lower part 207 has a through hole, through which a centering device 205 extends, which is attached to the upper part 206.
Diese Zentriervorrichtung ist an der Stirnseite zum Boden hin mit einer kugelförmigen Ausfräsung 205a versehen, so daß ein Kugelabschnitt seitlich eingeschoben werden kann. Ein entsprechender Kugelabschnitt ist auf einer Kreuzungsplatte 30 geschaffen, die anhand der Fig. 4 oder der Fig. 7 noch erläutert wird.This centering device is provided on the end face towards the bottom with a spherical cutout 205a, so that a spherical section can be inserted laterally. A corresponding spherical section is created on an intersection plate 30, which will be explained with reference to FIG. 4 or FIG. 7.
In der Fig. 7 ist eine Zentriervorrichtung 5 detaillierter dargestellt, die sowohl bei einem Transportwagen 1 der ersten Ausführungsform wie auch bei einem Transportwagen 201 gemäß der zweiten Ausführungsform verwendbar ist. Diese Zentriervorrichtung 5 umfaßt eine Drehkalotte 37, die um eine Achse 36 verschwenkbar ist. Die Schwenkbewegung der Drehkalotte 37 ist jedoch durch einen Anschlag 38 in einer Richtung begrenzt. In die andere Verschwenkrichtung ist eine Federvorspannkraft aufgebracht, so daß die an der Stirnseite der Drehkalotte 37 vorhandene Kugelabschnittsausfräsung auf ein entsprechendes Gegenstück 35 an einer Kreuzungsplatte 30 problemlos einschnappen kann.A centering device 5 is shown in more detail in FIG. 7, which can be used both in a transport carriage 1 of the first embodiment and in a transport carriage 201 according to the second embodiment. This centering device 5 comprises a rotating cap 37 which can be pivoted about an axis 36. However, the pivoting movement of the rotary cap 37 is limited in one direction by a stop 38. A spring prestressing force is applied in the other pivoting direction, so that the spherical section milling on the end face of the rotating cap 37 can easily snap onto a corresponding counterpart 35 on an intersection plate 30.
Die Fig. 8 zeigt einen schematischen Schienenplan für ein erfindungsgemäßes Papierrollen-Transportsystem, in dem Transportwagen der vorgenannten Art per Hand oder auf Abschnitten auch durch Schleppfördereinrichtungen automatisch bewegt werden können.FIG. 8 shows a schematic rail plan for a paper roll transport system according to the invention, in which transport carriages of the aforementioned type can be moved automatically by hand or on sections by drag conveyors.
Ein Schienenweg setzt sich hier aus zwei Laufschienen 60 zusammen, die parallel zueinander im Abstand der Laufelemente der Transportwagen voneinander beabstandet sind. In Kreuzungsbereichen der Schienenwegen sind Kreuzungsplatten 30 im Boden eingelassen. In den Kreuzungspunkten sind als Verlängerung der Laufschienen 60 Führungsnuten 32 in der Kreuzungsplatte eingefräst. Die Führungsnuten 32 besitzen eine Querschnittsform, die der der Führungsprofile der Laufschienen 60 entspricht. Außerdem besitzt jede Kreuzungsplatte 30 eine Dreh-Führungsnut 31, die wiederum eine Querschnittsform aufweist, die der Querschnittsform der Führungsnuten 32 und der Führungsprofile der Laufschienen 60 entspricht. Die Dreh-Führungsnut 31 verläuft kreisförmig und geht durch die Schnittpunkte der einzelnen Führungsnuten 32.A rail track here is composed of two running rails 60 which are spaced apart from one another parallel to one another at a distance from the running elements of the transport carriages. In crossing areas of the railroad tracks, crossing plates 30 are embedded in the floor. In the crossing points 60 guide grooves 32 are milled into the crossing plate as an extension of the running rails. The guide grooves 32 have a cross-sectional shape which corresponds to that of the guide profiles of the running rails 60. In addition, each crossing plate 30 has a rotary guide groove 31, which in turn has a cross-sectional shape that corresponds to the cross-sectional shape of the guide grooves 32 and the guide profiles of the running rails 60. The rotary guide groove 31 runs in a circle and passes through the intersections of the individual guide grooves 32.
Ein Detail X der Fig. 8 ist in der Fig. 10 gezeigt. Hieraus ist ersichtlich, daß durch das Ausfräsen der einzelnen Führungsnuten 31 und 32 im Kreuzungspunkt die Seitenführungen für die Laufkugeln der Transportwagen wegfallen. Im Gegenzug sind Scheiben 70 eingesetzt, die jeweils ein darin eingefrästes Kreuzprofil mit mulden- oder radienförmigem Querschnitt besitzen. Damit ist auch in den kritischen Bereichen der Kreuzungspunkte die Führung einer Laufrolle gewährleistet. Die muldenförmigen Führungsprofile 71 in der Scheibe 70 verlaufen in Verlängerung der Führungsnuten 32 einer Kreuzungsplatte 30. Die Scheiben 70 sind mit Unterlegscheiben 76 unterlegt. Bei längerem Einsatz der aus einem weicheren Material als die Scheiben 70 bestehenden Kreuzungsplatten 30 kommt es zu einem entsprechenden Verschleiß der Führungsnuten 32. Um diesen Verschleiß auszugleichen werden eine oder mehrere Unterlegscheiben 75 weggenommen, so daß die Scheiben 70 der tatsächlichen Höhe der Führungsnuten 32 angepaßt werden können.A detail X of FIG. 8 is shown in FIG. 10. From this it can be seen that the side guides by milling the individual guide grooves 31 and 32 at the intersection for the balls of the dolly. In return, disks 70 are used, each of which has a cross profile milled therein with a trough-shaped or radius-shaped cross section. This also ensures that a roller is guided in the critical areas of the crossing points. The trough-shaped guide profiles 71 in the disk 70 extend in the extension of the guide grooves 32 of an intersection plate 30. The disks 70 are underlaid with washers 76. If the crossing plates 30, which are made of a softer material than the disks 70, are used for a longer period of time, the guide grooves 32 will wear out accordingly. To compensate for this wear, one or more washers 75 are removed so that the disks 70 are adapted to the actual height of the guide grooves 32 can.
Aus der Fig. 9 ist schließlich noch eine schematische Querschnittsansicht durch eine Laufschiene 60 gezeigt, in der eine Laufkugel 4 abrollt. Als Verschleißschutz ist hier eine zusätzliche Stahlblecheinlage 60a eingesetzt, die mittels eines doppelseitigen Klebebands auf die Laufschiene aufgeklebt ist.Finally, FIG. 9 shows a schematic cross-sectional view through a running rail 60, in which a running ball 4 rolls. An additional sheet steel insert 60a is used as wear protection, which is glued to the running rail by means of double-sided adhesive tape.
Im folgenden wird nun der Transport einer Papierrolle 50 auf einem der Transportwagen 1 (201) erläutert. Hierfür wird das Rampenteil 11 an einen Transportwagen angesetzt. Durch Aufrollen einer Papierrolle 50 auf die Rampe 11 wird ab einer bestimmten Aufrollhöhe durch das Eigengewicht der Papierrolle die Rampe 11 gekippt. Der Rampenvorbau 11a fügt sich hierbei in die Seitenfläche des Auflageelementes 2 ein. Sodann kann der Transportwagen 1 mit darauf befindlicher Papierrolle 50 auf den Laufschienen 60 verschoben werden.The transport of a paper roll 50 on one of the transport carriages 1 (201) will now be explained. For this purpose, the ramp part 11 is attached to a transport trolley. By rolling a paper roll 50 onto the ramp 11, the ramp 11 is tilted from a certain roll height by the weight of the paper roll. The ramp stem 11a fits into the side surface of the support element 2. The transport carriage 1 with the paper roll 50 thereon can then be moved on the running rails 60.
Soll der Transportwagen 1 in einem Kreuzungsbereich vom bisherigen Schienenweg weggeführt werden, so wird der Transportwagen 1 soweit auf die Kreuzungsplatte geschoben, bis die Zentriereinrichtung 5 auf dem Kugelabschnitt 35 der Kreuzungsplatte einrastet. Dann wird der Transportwagen 1 auf dem Dreh-Führungsprofil 31 entlang gedreht, bis er unter Überwindung der Federkraft der Zentriervorrichtung auf dem neuen Schienenweg weitergerollt werden kann. Bei geradliniger Hinwegführung eines Transportwagens 1 über eine Kreuzungsplatte wird die Federkraft der Zentriervorrichtung zu überwinden sein.If the transport carriage 1 is to be led away from the previous rail path in an intersection area, the transport carriage 1 is pushed onto the crossing plate until the centering device 5 on the ball section 35 of the Intersection plate snaps into place. The transport carriage 1 is then rotated along the rotary guide profile 31 until it can be rolled on the new rail path while overcoming the spring force of the centering device. When a transport carriage 1 is guided in a straight line over a crossing plate, the spring force of the centering device will have to be overcome.
