Abstract

The invention relates to a planing device mounted on machines for processing ice. The inventive device is used in the area of the ice surface located close to the barrier and comprises a blade which is mounted with the carrier thereof on the lateral wall of the planing side that is provided on the machine. The planing device rests with an edge on the ice surface. The invention is characterized in that the blade can be moved from a lifted non-operating position into the working position by means of a driving mechanism.

Description

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 Eisoberfläche aufliegt.The invention relates to a planing device on machines for Ice conditioning for use in the area near the strip of ice, with a knife, which with its wearer on the left Machine side, preferably on the side wall of the at Machine existing planing slide is mounted, which with his skids rests on the ice surface.

An der Eiskante zur Bande wird bei öffentlichen Eislaufzeiten und Eishockeyspielen durch Bremsvorgänge der Benutzer Schnee (Eisabrieb) angehäuft. Durch den an den meisten Eisbereitungsmaschinen 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. At the ice edge the gang will be on public ice skating and ice hockey games by braking the user snow (Ice rub) piled up. By the most ice making machines mounted rotating strip broom becomes this snow only insufficiently removed. Especially with a large amount of snow thaws the snow, which grows down a layer of ice, against Which of the gang brooms is powerless. This to the gang Rising ice can from the planing aggregate of Ice machine can not be achieved because the outer edge of the Sliding carriage is formed by the sled runner and the Planer knife only starts inside the sled runner. These Arrangement is mandatory for ice making reasons. The grown Ice edge is disturbing for ice hockey players (playing with the puck). Very annoying this edge is also for the ice making. In close band ride with the planing slide slides Sled runner on this grown ice edge. This will the whole planer raised one-sided, resulting in the band side the problem intensified and turned away at the gang Planing side forms a depression. When the grown Ice edge is not removed regularly, the ice grows over the entire planing width to the band ever further.

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 the belt curves, the abrasion problem is lower. Therefore grows there by the water order as a result of centrifugal force Experience has shown that the entire ice layer The knife edge of the However, planets can not be closer due to the radius in the band curve as 200 to 250 mm to the gang.

Am Ein-/Ausfahrttor für die Eisbereitungsmaschine wächst das Eis bei nicht hunderprozentiger 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 that grows Ice with not one hundred percent manual removal of the Snow and water residues after departure of the machine from the Ice surface also fast. Are these undesirable heavy ice areas not planed regularly, the ice grows from the gang to the middle always further and stronger. This not only affects the ice quality, but causes also unnecessary energy costs.

Bisher erfolgte das Abhobeln der angewachsenen Eisbereiche nach folgenden Methoden:

  • 1. An die linke Aussenseite des Hobelschlittens wird ein Metallgestell mit einem ca. 30 cm langen Hobelmesser angeschraubt, mit der der Bandenbereich gehobelt wird. Der Einsatz dieses Hobels ist zeitaufwendig und schwierig.
  • 2. Ein von einem Batterie- oder Benzinmotor angetriebenes rotierendes Messer unter einem rasenmäherähnlichen Gerät wird manuell an der Bande entlang und über die sonstigen abzuhobelnden Eisflächen geführt.
  • 3. Die bisher komfortabelste Lösung ist ein klappbar auf dem 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.
    • Previously, the planing of the grown ice areas was carried out according to the following methods:
  • 1. On the left outside of the planing carriage, a metal frame is screwed with a planer blade of about 30 cm, with which the band area is planed. The use of this planer is time consuming and difficult.
  • 2. A powered by a battery or gasoline engine rotating knife under a lawn mower-like device is manually guided along the band and on the other abzuhobelnden ice surfaces.
  • 3. The most comfortable solution so far is a folding unit mounted on the planing slide with a rotating knife. This unit is folded by hand in the working position before planing the band area and reset after use.

    • Die Erfindung geht aus von einer Hobelvorrichtung, wie sie in der US-A- 4 372 617 beschrieben ist. Dort ist das Messer mittels eines Getriebes (Hydraulikzylinder) aus einer oberen Position in eine untere Arbeitsposition bewegbar. Der Nachteil dieser Vorrichtung ist jedoch darin zu sehen, dass der Fahrer der Eismaschine beim Hobelvorgang an der Bande ganz genau fahren muss, damit beim Hobelvorgang weder die Hobelvorrichtung noch die Bande selbst beschädigt wird.The invention is based on a planing device, as in US-A-4,372,617. There is the knife by means of a gearbox (hydraulic cylinder) from an upper one Position movable in a lower working position. The disadvantage However, this device is to be seen in the fact that the driver the ice machine during the planing process on the band exactly drive, so that during the planing process neither the planing device even the gang itself is damaged.

    Die meisten der vorgenannten Methoden erfordern eine oder mehrere separate Hobelfahrten 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.    Most of the aforementioned methods require one or more separate planer rides and leave the snow after the planing use in the band area, which in turn then usually requires several trips with the strip broom until the ice edge to the band on
    the entire length is really clean snow. An application of these methods during the normal, short ice-making times is completely excluded in the devices according to the items 1 and 2. Also in the method according to item 3, the banding requires a two-fold descent from the driver's seat and at least two additional rides along the band.

    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, a planing device of the aforementioned type so that the Ice edge at the field setting (rink) at rinks during any normal ice cream preparation without additional driving and Assembly effort can be processed continuously accurately.

    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 characteristic of the characterizing Part of claim 1. Further advantageous embodiments 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 Aussenrunde 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, on the left side wall of the planing carriage is an inwardly inclined, extendable and lowerable Knife attached, which without additional effort of Driver's seat can be used and on the entire outer round the ice edge to the band keeps exactly right angles. The expression "holds" is deliberately chosen, as with a regular use usually not really planed, but that The knife simply scrapes off the loose snow at the edge of the strip and by the inclination of the planer this under the Carriage leads to the conveyor, the integral part of the Ice machine is. Behind the striping machine is the ice surface perpendicular to the band, in one plane with the main blade, smooth and snow-free.

    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 Bandenhobels 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. Is in special circumstances, such as after a special heavily visited skating time or after several omissions of the outer lane a real planing the band edge required This is done by simply inserting the striping machine on the outer lane from the driver's seat without any additional Effort in the same way with the same result like scratching the snow off with regular use.

    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.A preferred embodiment of the invention, especially in the dependent claims are claimed as essential to the invention, is shown below with drawings and closer explained.

    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 Hobelspuren 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 planer remains permanently installed and is in the Internal lanes in the interior of the planing carriage (12) except Intervention at rest. To use the planer is this on the way to the gang before the actual band contact by actuating a lever from the driver's seat hydraulically in Work position extended. The knife is still there after that disengaged and left on the way to the gang no traces of planing on ice. The outer side of the knife carrier (6) is limited by a sliding block (10). This shoe (10) is determined by the ride of the ice-working machine against the Skirting (11) of the band pressed. By the side Pressure on the knife carrier (6) is this with the knife (7) up to the runner bottom edge (13) of the planing carriage (12) pressed down and thus in the engaged position. Reached This is characterized in that the knife carrier (6) sliding on the Planing beam 5 is held by three round bolts, which in Knife holder (6) guided in slanted oblong holes become.

    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.By force of a spring (8), the knife carrier (6) to the outside and the knife (7) is disengaged. By pressure of the shoe (10) against the skirting board (11) of the band the knife carrier (6) inwards and thus downwards and the Knife (7) pressed into the engaged position. The limitation of Knife engagement on the runner bottom edge (13) of the planing slide (12) is adjusted by a set screw (14).

    Nach Aufgabe des Bandenkontaktes ist die Messerfunktion automatisch beendet. Das Zurückfahren des Hobels in Ruhestellung erfolgt nur aus optischen Gründen.After abandonment of the band contact, the knife function is automatic completed. The return of the planer in rest position takes place 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 (23) 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 Eisbearbeitungsmaschine 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 also guaranteed in the band curves. For the lateral displacement possibility of the planer is the actual planing aggregate mounted on a slide rail (2) on the planer holder (1). The planing aggregate is moved by a hydraulic cylinder (20), the cylinder base on a second shoe (3) the slide rail (2) is slidably mounted. This shoe (3) becomes outwardly in its home position by a tension spring (9) held. Inside, the sliding distance of about 15 cm limited by a stop (23). The spring-sliding assembly the hydraulic cylinder (20) and thus the by the Hydraulic cylinder (20) moving planing unit causes a order the about 15 cm glide path floating ride along the planer the gang. This will be hard blows by any bumps cushioned the tape base and the ride of the ice-working machine needs for exact processing of the ice edge not to the millimeter to the gang, but may 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 planer blade by means of the adjusting screw (14) also set lower than the Schlittenkufe become. With a second set screw (15) can the planer blade also be determined in depth of engagement. This is one Planing without band contact e.g. for planing a wider one Track in the curve or in front of the open entrance / exit gate easily possible. This can be done on the outside of the Knife holder inside the shoe one in height adjustable auxiliary skid be provided, the one too deep Penetration of the knife into the ice prevented. These Repair trips are unnecessary at regular, appropriate Use of the band planer and are mainly for processing strongly grown ice surfaces at the first use of the Banded planes required in the middle of 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.
    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 Hobelhalterung 1 montiert sind.
    Gleiche Teile der Vorrichtung sind in den Zeichnungen mit gleichen Bezugszeichen versehen.    In the alternative embodiment according to Figures 4 to 6, the planing unit is also displaced by a hydraulic cylinder (20) whose cylinder base is mounted with a double slide rail (22) in a double slide bearing (21). The hydraulic cylinder is held by the tension spring (9) to the outside in its basic position. Inside, the sliding distance of about 15 cm is limited by a stop (23). With 24 a damping spring is designated.
    For the lateral displacement possibility of the planer, the actual planing unit, the planing beam 5 is guided by means of the two double plain bearings 21 on the two slide rails 22 which are mounted on the planing holder 1.
    Like parts of the device are provided with the same reference numerals in the drawings.
