Description

Hobel orrichtung an Maschinen zur Eisaufbereitung Planing device on ice-making machines
Die Erfindung betrifft eine Hobelvorrichtung an Maschinen zur Eisaufbereitung zum Einsatz im bandennahen Bereich der Eisfläche, mit einem Messer, welches mit seinem Träger an der linken Maschinenseite, vorzugsweise an der Seitenwand des an der Maschine vorhandenen Hobelschlittens montiert ist, welche mit seinen Kufen auf der Eisoberflache aufliegt.The invention relates to a planing device on machines for ice preparation for use in the area of the ice surface close to the board, with a knife which is mounted with its carrier on the left side of the machine, preferably on the side wall of the planing slide present on the machine, which with its runners on the ice surface lies on.
An der Eiskante zur Bande wird bei öffentlichen Eislaufzeiten und Eishockeyspielen durch Bremsvorgänge der Benutzer Schnee (Eisabrieb) angehäuft. Durch den an den meisten Eisbereitungs- maschinen montierten rotierenden Bandenbesen wird dieser Schnee nur ungenügend entfernt . Besonders bei großem Schneeanfall taut der Schnee an, wodurch unten eine Eisschicht anwächst, gegen welche der Bandenbesen machtlos ist . Diese zur Bande ansteigende Eisschicht kann von dem Hobelaggregat der Eismaschine nicht erreicht werden, weil die Außenkante des Hobelschlittens durch die Schlittenkufe gebildet ■ wird und das Hobelmesser erst innerhalb der Schlittenkufe beginnt. Diese Anordnung ist aus Eisbereitungsgründen zwingend. Die angewachsene Eiskante ist für Eishockeyspieler störend (Bandenspiel mit dem Puck) . Sehr störend ist diese Kante auch für die Eisbereitung. Bei naher Bandenfahrt mit dem Hobelschlitten gleitet die Schlittenkufe auf dieser angewachsenen Eiskante. Dadurch wird der ganze Hobel einseitig angehoben, wodurch sich an der Bandenseite das Problem verstärkt und sich an der der Bande abgewandten Hobelseite eine Vertiefung bildet. Wenn die angewachsene Eiskante nicht regelmäßig entfernt wird, wächst das Eis über die gesamte Hobelbreite zur Bande hin immer weiter an. An den Bandenkurven ist das Abriebproblem geringer. Dafür wächst dort durch den Wasserauftrag infolge Fliehkraft die gesamte Eisschicht erfahrungsgemäß an. Die Messerkante des Hobels kann aber radiusbedingt in der Bandenkurve nicht näher als 200 bis 250 mm an die Bande.At public ice skating times and ice hockey games, braking (ice abrasion) accumulates on the ice edge of the gang by braking. This snow is only insufficiently removed due to the rotating gang brooms mounted on most ice-making machines. The snow thaws, especially when there is a large amount of snow, causing an ice layer to grow below, against which the gang broom is powerless. This rising to the boundary layer of ice can not be reached by the planing unit of the ice machine because the outer edge of the plane slide is ■ formed by the slider rail and the planer blade begins only within the slider rail. This arrangement is mandatory for ice making reasons. The growing ice edge is disruptive for ice hockey players (gang play with the puck). This edge is also very annoying for ice making. The sled runner slides on this grown ice edge during a close gang ride with the planing sledge. As a result, the entire plane is lifted on one side, which increases the problem on the side of the board and forms a recess on the side of the plane facing away from the board. If the ice edge that has grown on is not removed regularly, the ice grows further and further across the entire planing width towards the board. The abrasion problem on the band curves is less. Experience shows that the entire ice layer grows there due to centrifugal force. The knife edge of the planer cannot be closer to the board than 200 to 250 mm due to the radius in the board curve.
Am Ein-/Ausfahrttor für die Eisbereitungsmaschine wächst das Eis bei nicht hundertprozentiger manueller Entfernung der Schnee- und Wasserreste nach Abfahrt der Maschine von der Eisfläche ebenfalls schnell an. Werden diese unerwünscht starken Eisbereiche nicht regelmäßig abgehobelt, wächst das Eis von der Bande zur Mitte immer weiter und stärker an. Dies beeinträchtigt nicht nur die Eisqualität, sondern verursacht auch unnötige Energiekosten.At the entrance / exit gate for the ice making machine, the ice also grows quickly when the snow and water residues are not removed manually after the machine has left the ice surface. If these undesirably strong ice areas are not planed out regularly, the ice grows more and more from the board to the center. This not only affects the ice quality, but also causes unnecessary energy costs.
Bisher erfolgte das Abhobeln der angewachsenen Eisbereiche nach folgenden Methoden:So far, the growing ice areas have been planed using the following methods:
1. An die linke Aussenseite des Hobelschlittens wird ein Me- tallgestell mit einem ca. 30 cm langen Hobelmesser angeschraubt, mit dem der Bandenbereich gehobelt wird. Der Einsatz dieses Hobels ist zeitaufwendig und schwierig.1. A metal frame with an approx. 30 cm long planing knife is screwed onto the left outside of the planing slide, with which the board area is planed. Using this plane is time consuming and difficult.
2. Ein Batterie- oder Benzinmotor angetriebenes rotierendes2. A battery or petrol motor powered rotating
Messer unter einem rasenmäherähnlichen Gerät wird manuell an der Bande entlang und über die sonstigen abzuhobelnden Eisflächen geführt.Knives under a lawnmower-like device are manually guided along the board and over the other ice surfaces to be planed.
3. Die bisher komfortabelste Lösung ist ein klappbar auf dem3. The most comfortable solution so far is a foldable on the
Hobelschlitten montiertes Hobelaggregat mit einem rotierenden Messer. Dieses Aggregat wird vor dem Hobeln des Bandenbereichs von Hand in Arbeitsposition geklappt und nach dem Einsatz wieder zurückgestellt.Planing slide mounted planing unit with a rotating knife. This unit is folded into the working position by hand before planing the board area and put back after use.
Alle diese Methoden erfordern eine oder mehrere separate Hobel - fahrten und lassen den Schnee nach dem Hobeleinsatz im Bandenbereich liegen, was wiederum anschließend meist mehrere Fahrten mit dem Bandenbesen erfordert, bis die Eiskante zur Bande über die gesamte Länge wirklich sauber schneefrei ist. Eine Anwendung dieser Methoden während der normalen, kurzen Eisbereitungszeiten ist bei den Vorrichtungen gemäß den Punkten 1 und 2 völlig ausgeschlossen. Auch bei der Methode gemäß Punkt 3 erfordert das Bandenhobeln ein zweimaliges Absteigen vom Fahrersitz und mindestens zwei zusätzliche Fahrten entlang der Bande.All these methods require one or more separate planing runs and leave the snow in the area of the board after the planing operation, which in turn usually requires several trips with the board brush until the ice edge over the board the entire length is really clean snow free. Use of these methods during normal, short ice making times is completely ruled out for the devices according to items 1 and 2. Even with the method according to point 3, gouging requires two descents from the driver's seat and at least two additional trips along the gang.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Hobelvorrichtung der eingangs genannten Art so auszubilden, daß die Eiskante an der Spielfeldeinfassung (Bande ) an Eisbahnen während jeder normalen Eisbereitung ohne zusätzlichen Fahr- und Montageaufwand kontinuierlich exakt bearbeitet werden kann.The invention is therefore based on the object of designing a planing device of the type mentioned in such a way that the ice edge on the playing field border (gang) on ice rinks can be continuously and precisely machined during any normal ice making without additional driving and assembly work.
Die Erfindung löst diese Aufgabe gemäß dem Merkmal des kennzeichnenden Teils des Anspruchs 1. Weitere vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.The invention solves this problem according to the feature of the characterizing part of claim 1. Further advantageous embodiments of the invention are the subject of the dependent claims.
Beispielsweise an der linken Seitenwand des Hobelschlittens wird ein nach innen schräggestelltes , ausfahrbares und absenkbares Messer angebracht, welches ohne zusätzlichen Aufwand vom Fahrersitz eingesetzt werden kann und auf der gesamten Aussen- runde die Eiskante zur Bande exakt rechtwinklig hält. Der Ausdruck "hält" ist bewußt gewählt, da bei einem regelmäßigen Einsatz meistens gar nicht wirklich gehobelt wird, sondern das Messer lediglich den losen Schnee an der Bandenkante wegkratzt und durch die Schrägstellung des Hobels diesen unter den Schlitten zum Förderer führt, der integraler Bestandteil der Eismaschine ist. Hinter dem Bandenhobel ist die Eisfläche rechtwinklig zur Bande, in einer Ebene mit dem Hauptmesser, glatt und schneefrei.For example, an inwardly inclined, extendable and lowerable knife is attached to the left side wall of the planer, which can be used by the driver's seat without additional effort and which keeps the ice edge at right angles to the board on the entire outside round. The term "holds" is chosen deliberately, because with regular use it is usually not really planed at all, but the knife simply scrapes away the loose snow at the edge of the belt and, through the inclined position of the plane, leads it under the carriage to the conveyor, which is an integral part of the Ice machine is. Behind the boarding plane the ice surface is perpendicular to the board, in a plane with the main knife, smooth and free of snow.
Ist bei besonderen Verhältnissen, etwa nach einer besonders stark besuchten Eislaufzeit oder nach mehrmaligem Auslassen der äußeren Fahrspur ein wirkliches Hobeln der Bandenkante erforderlich, geschieht dies durch einfaches Einsetzen des Bandenho- bels auf der äußeren Fahrspur vom Fahrersitz aus ohne jeden zusätzlichen Aufwand in gleicher Weise mit dem gleichen Ergebnis wie beim "Schnee wegkratzen " beim regelmäßigen Einsatz. Eine bevorzugte Ausführungsform der Erfindung, die vor allem in den Unteransprüchen als erfindungswesentlich beansprucht wird, wird im folgenden anhand von Zeichnungen dargestellt und näher erläutert.If, in special circumstances, such as after a particularly heavily frequented ice skating period or after repeated omission of the outer lane, a real planing of the edge of the board is required, this is done by simply inserting the board plane in the outer lane from the driver's seat in the same way without any additional effort the same result as with "scraping snow" with regular use. A preferred embodiment of the invention, which is claimed as essential to the invention in particular in the subclaims, is illustrated and explained in more detail below with reference to drawings.

Die Hobelvorrichtung bleibt ständig montiert und ist bei den inneren Fahrspuren im Innenbereich des Hobelschlittens (12) außer Eingriff in Ruhestellung. Zum Einsatz des Hobels wird dieser auf der Fahrt zur Bande vor dem eigentlichen Bandenkontakt durch Betätigung eines Hebels vom Fahrersitz aus hydraulisch in Arbeitsstellung ausgefahren. Das Messer ist danach immer noch außer Eingriff und hinterläßt auf dem Weg zur Bande keine Ho- belspuren auf dem Eis. Die äußere Seite des Messerträgers (6) wird durch einen Gleitschuh (10) begrenzt. Dieser Gleitschuh (10) wird durch die Fahrt der Eisbearbeitungsmaschine gegen die Sockelleiste (11) der Bande gedrückt. Durch den seitlichen Druck auf den Messerträger (6) wird dieser mit dem Messer (7) bis zur Kufenunterkante (13) des Hobelschlittens (12) nach unten und damit in die Eingriffsposition gedrückt. Erreicht wird dies dadurch, daß der Messerträger (6) gleitend auf dem Hobelträger 5 durch drei Rundbolzen gehalten wird, welche im Messerträger (6) in schräggestellten Langlöchern geführt werden .The planing device remains permanently installed and is in the idle position in the inner lanes in the interior of the planing carriage (12). To use the plane, it is extended hydraulically from the driver's seat into the working position on the journey to the board before the actual board contact by actuating a lever. After that, the knife is still out of engagement and leaves no marks on the ice on the way to the gang. The outer side of the knife holder (6) is delimited by a sliding block (10). This slide shoe (10) is pressed against the skirting board (11) of the gang by the movement of the ice processing machine. Due to the lateral pressure on the knife carrier (6), it is pressed down with the knife (7) to the lower runners edge (13) of the planing carriage (12) and thus into the engaged position. This is achieved in that the knife carrier (6) is slidably held on the plane carrier 5 by three round bolts which are guided in the knife carrier (6) in obliquely oblong holes.
Durch Kraft einer Feder (8) wird der Messerträger (6) nach außen und das Messer (7) außer Eingriff gedrückt. Durch Andruck des Gleitschuhs (10) gegen die Sockelleiste (11) der Bande wird der Messerträger (6) nach innen und damit nach unten und das Messer (7) in Eingriffsposition gedrückt. Die Begrenzung des Messereingriffs auf die Kufenunterkante (13) des Hobelschlittens (12) ist durch eine Stellschraube (14) eingestellt.The knife carrier (6) is pressed outwards and the knife (7) is disengaged by the force of a spring (8). By pressure of the sliding block (10) against the skirting board (11) of the board, the knife carrier (6) is pressed inwards and thus downwards and the knife (7) into the engaged position. The limitation of the knife engagement on the lower edge of the runner (13) of the planing slide (12) is set by an adjusting screw (14).
Nach Aufgabe des Bandenkontaktes ist die Messerfunktion automatisch beendet. Das Zurückfahren des Hobels in Ruhestellung erfolgt nur aus optischen Gründen.The knife function ends automatically after the contact with the strip has been given up. The planer is retracted in the rest position only for visual reasons.
Der Hobel kann soweit ausgefahren werden, daß die Funktion auch in den Bandenkurven gewährleistet ist. Für die seitliche Verschiebemöglichkeit des Hobels ist das eigentliche Hobelaggregat auf einer Gleitschiene (2) auf der Hobelhalterung (1) montiert. Verschoben wird das Hobelaggregat durch einen Hydraulikzylinder (20), dessen Zylinderbasis auf einem zweiten Gleitschuh (3) auf der Gleitschiene (2) gleitend montiert ist. Dieser Gleitschuh (3 ) wird durch eine Zugfeder (9) nach außen in seiner Grundposition gehalten. Nach innen wird die Gleitstrecke von ca. 15 cm durch einen Anschlag (20) begrenzt. Die federnd gleitende Montage des Hydraulikzylinders (20) und damit des durch den Hydraulikzylinder (20) bewegten Hobelaggregats bewirkt eine um den etwa 15 cm Gleitweg schwimmende Fahrt des Hobels entlang der Bande. Dadurch werden harte Schläge durch eventuelle Unebenheiten des Bandensockels abgefedert und die Fahrt der Eis- bearbeitungsmaschine braucht zur exakten Bearbeitung der Eiskante zur Bande nicht millimetergenau zu sein, sondern darf ca. 15 cm schwanken.The planer can be extended so far that the function is also guaranteed in the band curves. The actual planing unit is mounted on a slide rail (2) on the planing bracket (1) so that the planer can be moved sideways. The planing unit is moved by a hydraulic cylinder (20), the cylinder base of which is slidably mounted on a second slide shoe (3) on the slide rail (2). This slide shoe (3) is held outwards in its basic position by a tension spring (9). The sliding distance of approx. 15 cm is limited on the inside by a stop (20). The spring-sliding assembly of the hydraulic cylinder (20) and thus of the planing unit moved by the hydraulic cylinder (20) causes the planer to travel along the board, floating around the 15 cm glide path. As a result, hard impacts are cushioned by any unevenness in the base of the board, and the movement of the ice processing machine does not need to be accurate to the millimeter to precisely process the ice edge to the board, but may fluctuate around 15 cm.
Für besondere Einsätze kann das Hobelmesser mittels der Stellschraube (14) auch tiefer als die Schlittenkufe eingestellt werden. Mit einer zweiten Stellschraube (15) kann das Hobelmesser auch in Eingriffstiefe festgestellt werden. Damit ist ein Hobeln auch ohne Bandenkontakt z.B. zum Hobeln einer breiteren Spur in der Kurve oder vor dem offenen Ein-/Ausfahrtstor problemlos möglich. Hierzu kann an der Aussenseite des Messerträgers innerhalb des Gleitschuhs eine in der Höhe verstellbare Hilfskufe vorgesehen sein, die ein zu tiefes Eindringen des Messers in das Eis verhindert. Diese Reparaturfahrten erübrigen sich bei regelmäßigem, sachgemäßen Einsatz des Bandenhobels und sind vor allem zur Bearbeitung von stark angewachsenen Eisflächen beim erstmaligen Einsatz des Bandenhobels mitten in der Eissaison erforderlich.For special applications, the planing knife can also be set lower than the sled runner using the adjusting screw (14). With a second set screw (15) the planer knife can also be locked in the engagement depth. This means that planing is possible without any contact with the board, e.g. for planing a wider track in the curve or in front of the open entrance / exit gate. For this purpose, a height-adjustable auxiliary skid can be provided on the outside of the knife carrier within the sliding block, which is too deep Prevents the knife from penetrating the ice. These repairs are not necessary if the board slicer is used regularly and correctly and are particularly necessary for working on heavily grown ice surfaces when the board slicer is used for the first time in the ice season.
Bei der alternativen Ausführungsform gemäß den Figuren 4 bis 6 wird das Hobelaggregat ebenfalls durch einen Hydraulikzylinder (20) verschoben, dessen Zylinderbasis mit einer Doppel- Gleitschiene (22) in einem Doppel-Gleitlager (21) gelagert ist. Der Hydraulikzylinder wird durch die Zugfeder (9) nach aussen in seiner Grundposition gehalten. Nach innen wird die Gleitstrecke von ca. 15 cm durch einen Anschlag (23) begrenzt. Mit 24 ist eine Dämpfungsfeder bezeichnet.In the alternative embodiment according to FIGS. 4 to 6, the planing unit is also displaced by a hydraulic cylinder (20), the cylinder base of which is supported by a double slide rail (22) in a double slide bearing (21). The hydraulic cylinder is held outwards in its basic position by the tension spring (9). The sliding distance of approx. 15 cm is limited on the inside by a stop (23). At 24, a damping spring is designated.
Für die seitliche Verschiebemöglichkeit des Hobels wird das eigentliche Hobelaggregat, der Hobelträger 5 mittels der zwei Doppelgleitlager 21 auf den zwei Gleitschienen 22 geführt, welche auf der Hobelhaiterung 1 montiert sind.For the lateral displacement possibility of the planer, the actual planing unit, the planing support 5, is guided on the two slide rails 22 by means of the two double sliding bearings 21, which are mounted on the planing bracket 1.
