Description

Die Erfindung bezieht sich auf eine Beziehpresse für Polsterteile, mit der ein hüllenförmiger Bezug auf einen Polsterkörper aufziehbar ist. Die Beziehpresse hat ein Maschinengestell, an dem erste und diesen gegenüberliegende zweite Pressmittel, vorzugsweise Druckstangen, vorgesehen sind, zwischen denen ein Polsterkörper einlegbar ist. Sie können in eine Öffnungsposition, in der ein Polsterkörper zwischen die ersten und zweiten Pressmittel einlegbar ist, und eine Presstellung, in der der eingelegte Polsterkörper so zusammengepreßt wird, daß der Bezug über den Polsterkörper und die Pressmittel gestülpt werden kann, gebracht werden.The invention relates to a reference press for upholstery parts with which an envelope-shaped cover can be drawn onto a cushion body. The relationship press has a machine frame on the first and opposite second pressing means, preferably push rods, are provided between which a cushion body can be inserted. You can go to an open position in which a cushion body between the first and second pressing means is insertable, and a press position in which the inserted cushion body is pressed together so that the cover over the cushion body and the pressing means can be put over.

Eine derartige Beziehpresse ist z. B. aus der DE-B-21 51 966 bekannt. Der Polsterkörper ist beispielsweise ein Schaumstoffkissen, eine Matratze oder ein mit Polstermaterial gefülltes Inlett. Der Bezug ist normalerweise eine Hülle, die aus Polsterstoff genäht ist. Der Bezug kann aber auch ein Trikotmaterial sein, das zwischen einem Schaumstoffkörper und einem Bezug aus Möbelstoff angeordnet wird, siehe EP 136 766. Das Polsterteil ist ein mit einem Bezug überzogener Polsterkörper. Weiterhin ist aus der EP 0180 018 eine Vorrichtung zum Anbringen von Überzügen an Rümpfen, insbesondere bei Autositzrückenlehnen, sowie Verfahren zum Überziehen eines Rumpfes mittels einer solchen Vorrichtung bekannt.Such a relationship press is e.g. B. known from DE-B-21 51 966. The Upholstered body is, for example, a foam cushion, a mattress or a ticking filled with cushioning material. The reference is usually one Cover sewn from upholstery. The cover can also be a jersey material be that between a foam body and a cover is made of upholstery fabric, see EP 136 766. The upholstered part is a with a cover upholstered body. Furthermore, EP 0180 018 Device for applying covers to fuselages, in particular for car seat backrests, and Method for covering a fuselage using such a device is known.

Durch die ersten und die diesen gegenüberliegenden, zweiten Pressmittel wird ein Polsterkörper soweit zusammengedrückt, daß der Bezug über den Polsterkörper und die an diesem anliegenden Pressmittel gestülpt werden kann.Through the first and the second pressing means opposite these a cushion body is compressed so far that the cover over the Upholstery body and the pressing means lying against it are put over can.

Ein normaler Arbeitsablauf der Beziehpresse der eingangs genannten Art verläuft wie folgt: 1. Die Pressmittel befinden sich in der Öffnungsposition. Ein Polsterkörper kann zwischen die Pressmittel eingelegt werden, die Pressmittel sind ausreichend voneinander entfernt, damit dieses Einlegen einfach möglich ist. 2. Nun wird durch die Pressmittel der Polsterkörper soweit zusammengepreßt, daß der Bezug aufgestülpt werden kann. Die Pressmittel befinden sich in der Pressposition. 3. Ist der Bezug aufgestülpt und sitzt er richtig, wird der Druck auf den Polsterkörper wieder weggenommen, die Pressmittel können sich wieder in Richtung Öffnungsposition bewegen. 4. Nun kann nun entweder das Polsterteil oben weggezogen werden oder die Druckmittel werden in das Maschinengestell eingezogen. In jedem Fall werden die Pressmittel, die sich noch zwischen Bezug und Polsterkörper befinden, herausbewegt, sodaß das fertige Polsterteil vorliegt.A normal workflow of the relationship press of the type mentioned at the beginning proceeds as follows: 1. The pressing means are in the open position. A cushion body can be inserted between the pressing means Pressing media are sufficiently distant from each other for this to be inserted is easily possible. 2. Now the upholstery is made by the pressing means pressed so far that the cover can be put on. The Press media are in the press position. 3. Is the cover turned up and if it is seated correctly, the pressure on the upholstered body is released, the pressing means can move back towards the opening position move. 4. Now either the upholstery part can be pulled away or the pressure medium is drawn into the machine frame. In In any case, the pressing means that are still between the cover and the cushion body are moved out so that the finished upholstery part is present.

Die nach diesem Verfahren arbeitende Beziehpresse der eingangs genannten Art hat allerdings einen Nachteil: Wird in der Öffnungsposition ein Polsterkörper zwischen die Pressmittel eingelegt, so ist der Polsterkörper nicht fixiert, er wird von den Pressmitteln noch nicht gehalten. Um den Polsterkörper in die richtige Position bezüglich der Pressmittel zu bringen, muß er zunächst gehalten werden, die Pressmittel müssen in die Pressposition bewegt werden. In dieser ist der Polsterkörper nicht mehr gegenüber den Pressmitteln bewegbar. Erst dann muß der Polsterkörper nicht mehr gehalten werden.The reference press of the above mentioned working according to this procedure Art, however, has one disadvantage: it becomes a cushion body in the open position inserted between the pressing means, so is the cushion body not fixed, it is not yet held by the press media. To the To bring the cushion body into the correct position with regard to the pressing means, it must first be held, the pressing means must be in the pressing position be moved. In this the cushion body is no longer opposite the pressing means movable. Only then does the cushion body no longer have to being held.

Nun kann es aber passieren, daß man versehentlich einen Finger, eine Hand oder den Arm zwischen einem Pressmittel und dem Polsterkörper beläßt, wenn die Pressmittel von der Öffnungsposition in die Pressposition bewegt werden. Da für das Zusammenpressen des Polsterkörpers bis zu dem Zustand, daß der Bezug ohne größeren Aufwand aufgestülpt werden kann, ein gewisser Druck benötigt wird, können erhebliche Verletzungen auftreten, wenn ein Körperteil eingeklemmt wird.Now it can happen that you accidentally put a finger, a hand or leaves the arm between a press and the cushion body, when the pressing means moves from the opening position to the pressing position become. As for the compression of the cushion body to the state that the cover can be put on without much effort, a certain pressure is required, serious injuries can occur if a part of the body gets caught.

Die Erfindung hat es sich zur Aufgabe gemacht, die vorbekannte Beziehpresse so weiterzubilden, daß der Polsterkörper nicht mehr gehalten werden muss, wenn die Pressmittel in die Pressposition bewegt werden. Gelöst wird diese Aufgabe durch eine Beziehpresse nach dem Patentanspruch 1.The invention has set itself the task to further develop the known relationship press in such a way that the cushion body no longer has to be held when the pressing means are moved into the pressing position. This task is solved by a relationship press according to the patent claim 1.

Erfindungsgemäß ist die Beziehpresse in eine Zwischenposition bewegbar. Die erfindungsgemäße Beziehpresse ist so ausgebildet, daß sie nicht mehr unmittelbar von der Öffnungsposition in die Pressposition bewegt werden kann, vielmehr muß zunächst die Zwischenposition eingenommen werden, bevor die Pressposition erreichbar ist. In der Zwischenposition wird der Polsterkörper gerade so ausreichend durch die Druckmittel gedrückt, daß der fixiert ist, ein eingeklemmtes Körperteil aber ohne weiteres noch zwischen Pressmittel und Polsterkörper weggezogen werden kann, in jedem Fall aber nur so stark gepreßt wird, daß keine Verletzungen möglich sind.According to the invention, the cover press can be moved into an intermediate position. The reference press according to the invention is designed so that it no longer can be moved directly from the opening position to the pressing position can, rather the intermediate position must first be taken, before the pressing position can be reached. In the intermediate position the Upholstery body pressed just enough by the pressure medium that which is fixed, but a pinched body part between Press media and cushion body can be pulled away in each Case is only pressed so hard that no injuries are possible.

Dadurch ist es nur noch beim Übergang von der Öffnungsposition in die Zwischenposition notwendig, den Polsterkörper zu halten. Sobald die Zwischenposition erreicht ist, ist der Polsterkörper ausreichend fixiert, er kann zwar gegenüber den Pressmitteln noch verschoben werden, selbsttätig kann er sich aber nicht mehr verschieben. Um nun aus der Zwischenposition in die Pressposition zu gelangen werden beide Hände so für den Schaltvorgang eingesetzt, daß es unmöglich ist, den Schaltvorgang für die Pressposition durchzuführen, aber dennoch eine Hand, einen Finger oder einen Arm zwischen einem Pressmittel und dem Polsterkörper einzuklemmen.As a result, it is only in the transition from the open position to the Intermediate position necessary to hold the cushion body. Once the intermediate position is reached, the cushion body is sufficiently fixed, he can still be moved compared to the pressing means, automatically but he can’t move anymore. Now from the intermediate position Both hands will be in the pressing position for the Shifting used that it is impossible to shift for the Press position, but still a hand, a finger or pinching an arm between a pressing means and the cushion body.

In einer bevorzugten Weiterbildung ist für die Betätigung der Beziehpresse aus der Öffnungsposition in die Zwischenposition ein Fußschalter vorgesehen. Er ermöglicht es, daß beide Hände für das Halten des Polsterkörpers frei bleiben, bis der Polsterkörper in der Zwischenposition ausreichend fixiert ist.In a preferred development is for the operation of the relationship press a foot switch is provided from the open position to the intermediate position. It allows both hands to hold the cushion body remain free until the cushion body is sufficient in the intermediate position is fixed.

Für den Schaltvorgang aus der Zwischenposition in die Pressposition werden beide Hände benötigt. Sie müssen zwei Schalter unabhängig betätigen, um den Übergang in die Pressposition einleiten zu können. In einer anderen Ausführung muß eine Hand einen Schalter betätigen, die andere muß aber eine entsprechende Sicherheitsvorrichtung auslösen. Es ist auch nicht möglich, einen dieser Schalter ständig zu betätigen, indem beispielsweise ein Gegenstand auf ihn gelegt wird. Dies reicht für die Auslösung eines Schaltvorgangs nicht aus, vielmehr muß der Schalter jeweils erneut betätigt werden. Er ist daher vorzugsweise als Druckkontaktschalter ausgeführt.For the switching process from the intermediate position to the pressing position both hands needed. You have to operate two switches independently, to initiate the transition to the press position. In another One hand must operate a switch, the other must but trigger a corresponding safety device. It is not possible to operate one of these switches continuously, for example by an object is placed on it. This is enough to trigger one Switching process not off, rather the switch must be pressed again become. It is therefore preferably designed as a pressure contact switch.

Die Pressmittel können jeweils eine Platte sein, in einer bevorzugten Ausführung sind es Druckstangen. Die Pressmittel sind vorzugsweise lösbar mit Haltern verbunden, die mit dem Antrieb für den Pressvorgang in Verbindung stehen. Dadurch können die Pressmittel, beispielsweise Druckstangen, ausgewechselt werden. Es kann so die jeweils passende Länge, abhängig von der Größe des Polsterkörpers, eingesetzt werden.The pressing means can each be a plate, in a preferred embodiment are push rods. The pressing means are preferably releasable connected to holders which are connected to the drive for the pressing process stand. As a result, the pressing means, for example push rods, be replaced. So it can be the appropriate length, depending of the size of the upholstered body.

In einer bevorzugten Ausführung sind die Pressmittel nach innen in das Gehäuse des Maschinengestells, einziehbar. Dies erleichtert einerseits das Entfernen der Pressmittel vom fertiggestellten Polsterteil, erspart also einen manuellen Arbeitsvorgang, andererseits läßt sich die Beziehpresse einfacher aufbewahren und transportieren.In a preferred embodiment, the pressing means are inside Machine frame housing, retractable. On the one hand, this makes it easier Removing the pressing agent from the finished upholstery part, so saves a manual process, on the other hand, the relationship press easier to store and transport.

  • FIG. 4 : a detail from the representation according to FIG. 3, but in the pressing position, a cover is placed over the pressed cushion body and
  • FIG. 5 : a perspective illustration similar to FIG. 1 for an exemplary embodiment.
  • Wie aus den Figuren ersichtlich ist, hat die Beziehpresse ein Maschinengestell 20 in Form eines im wesentlichen geschlossenen Gehäuses. In ihm befinden sich die Steuerungsvorrichtungen und Antriebe. Aus einer Öffnung in der Oberseite des Maschinengestells 20 ragen erste und zweite Pressmittel 22, 24 nach oben vor. Sie bestehen im gezeigten Ausführungsbeispiel jeweils aus einer Leiste 26 und drei Druckstangen 28, die von einer Leiste 26 ausgehen. Der Zwischenbereich zwischen den beiden Leisten 26 ist durch eine nachgiebige Abdeckung 30 verschlossen. As can be seen from the figures, the cover press has a machine frame 20 in the form of a substantially closed housing. Are in it the control devices and drives. From an opening first and second pressing means protrude in the upper side of the machine frame 20 22, 24 upwards. They exist in the embodiment shown each from a bar 26 and three push rods 28, the one bar 26 going out. The intermediate area between the two strips 26 is through a resilient cover 30 closed.

    Die Figuren 1 und 2 zeigen die Beziehpresse in der Öffnungsposition. Figur 2 zeigt einen Polsterkörper 32 zwischen den beiden Pressmitteln 22, 24. In der gezeigten Position hält der Polsterkörper 32 nicht, er muß vielmehr irgendwie gehalten werden, beispielsweise mittels der Hände einer Bedienperson.Figures 1 and 2 show the reference press in the open position. Figure 2 shows a cushion body 32 between the two pressing means 22, 24. In In the position shown, the cushion body 32 does not hold, but rather must are somehow held, for example by the hands of an operator.

    Figur 3 zeigt die Beziehpresse in einer Zwischenposition. In dieser sind die ersten und zweiten Pressmittel 22, 24 bereits locker an den Polsterkörper 32 herangeführt, sie liegen am Polsterkörper 32 mit gelindem Druck an. Der Anlagedruck ist so bemessen, daß keine Probleme auftreten wenn eine Hand zwischen einem Pressmittel 22 oder 24 und dem Polsterkörper 32 verbleibt. In der Zwischenposition (FIG. 3) ist der Polsterkörper 32 so gegenüber den Pressmitteln 22, 24 fixiert, daß er nun nicht mehr abgestützt werden muß. Er kann aber noch gegenüber den Pressmitteln 22, 24 verschoben werden, beispielsweise seitlich oder nach oben.Figure 3 shows the reference press in an intermediate position. In this are the first and second pressing means 22, 24 already loosely on the cushion body 32 brought up, they rest on the cushion body 32 with gentle pressure. The System pressure is dimensioned so that no problems occur when one hand remains between a pressing means 22 or 24 and the cushion body 32. In the intermediate position (FIG. 3), the cushion body 32 is thus opposite the Pressing means 22, 24 fixes that it no longer has to be supported. However, it can still be moved relative to the pressing means 22, 24, for example sideways or upwards.

    Figur 4 zeigt die Pressposition. Der Abstand der Pressmittel 22, 24 ist nun geringer als in der Darstellung gemäß Figur 3, der Polsterkörper 32 ist zusammengedrückt. Es wird ein Bezug 34 auf die zusammengedrückte Einheit aus Polsterkörper 32 und den Pressmitteln 22, 24 von oben aufgestülpt, die Aufstülpbewegung ist durch einen Pfeil kenntlich gemacht. Wäre in dieser Position eine Hand zwischen den Pressmitteln 22 oder 24 und dem gepreßten Polsterkörper 32 eingeklemmt, könnte es zu Verletzungen kommen.Figure 4 shows the pressing position. The distance between the pressing means 22, 24 is now less than in the illustration according to FIG. 3, the cushion body 32 pressed together. It becomes a reference 34 to the compressed unit upholstered body 32 and the pressing means 22, 24, which An upward movement is indicated by an arrow. Would be in this Position a hand between the pressing means 22 or 24 and the pressed one If the cushion body 32 is jammed, injuries could result.

    Ist der Bezug 34 vollständig auf die genannte Einheit aus Polsterkörper 32 und Pressmitteln 22, 24 aufgestülpt, wird in einem nächsten Schritt der Pressdruck abgeschaltet, die Pressmittel 22, 24 werden nach innen in das Gehäuse des Maschinengestells 20 eingezogen, das fertige Polsterteil kann nun entnommen werden.Is the reference 34 completely to the unit made of cushion body 32 and pressing means 22, 24 put on, in a next step the Pressing pressure switched off, the pressing means 22, 24 are turned into the inside Housing of the machine frame 20 retracted, the finished upholstery can can now be removed.

    Um von der Öffnungsposition in die Zwischenposition zu gelangen, wird der Beziehpresse ein entsprechender Befehl gegeben. Im gezeigten Ausführungsbeispiel erfolgte dies durch einen Fußschalter 36. Um aus der Zwischenposition in die Pressposition zu gelangen, wird der Beziehpresse ein entsprechender Steuerbefehl manuell eingegeben, für den beide Hände der Bedienperson unabhängig voneinander benötigt werden. Dadurch ist ausgeschlossen, daß die Hände der Bedienperson noch am Polsterkörper 32 sein können, vielmehr muß die Bedienperson den Polsterkörper 32 loslassen, um den Steuerbefehl eingeben zu können. Im gezeigten Ausführungsbeispiel sind an beiden Schmalseiten 38 des Maschinengestells 20 Schalter 40 vorgesehen, von denen aus den Figuren nur der Schalter 40 einer Schmalseite 38 ersichtlich ist. Der Schalter 40 der gegenüberliegenden Schmalseite ist genauso angeordnet und ausgeführt.To move from the open position to the intermediate position, the Given press a corresponding command. In the embodiment shown this was done by a foot switch 36. To from the intermediate position To get into the press position, the relationship press becomes a corresponding one Control command entered manually, for both hands of the Operator are needed independently. This prevents that the operator's hands are still on the cushion body 32 can, rather the operator must release the cushion body 32 to to be able to enter the control command. In the embodiment shown 20 switches 40 are provided on both narrow sides 38 of the machine frame, of which only the switch 40 of a narrow side 38 from the figures can be seen. The switch 40 is on the opposite narrow side arranged and executed in the same way.

    Nur wenn die Bedienperson beide Schalter 40 betätigt, kann die Beziehpresse von der Zwischenposition in die Pressposition gebracht werden. Die Schalter 40 sind so ausreichend weit von den sich bewegenden Teilen der Beziehpresse entfernt, daß ein Einklemmen von Körperteilen nicht möglich ist.Only when the operator operates both switches 40 can the reference press be brought from the intermediate position into the pressing position. The Switches 40 are sufficiently far from the moving parts of the Relative press removed that pinching body parts is not possible is.

    Bei den Schaltern 40 handelt es sich vorzugsweise um Druckkontakte, die normalerweise federbelastet in der Öffnungsstellung stehen. Nur wenn sie gedrückt werden, ist der Schalter geschlossen. Die (elektrische) Steuervorrichtung ist so geschaltet, daß nur bei geschlossenen Druckschaltern 40 der Übergang in die Pressposition möglich ist. Es sind auch andere Ausführungen möglich. So können die Schalter 40 als Berührungsschalter ausgeführt sein, die beschriebenen Druckschalter können auch in der gedrückten Stellung öffnen, die Schalter können pneumatische oder hydraulische Schalter sein. Es können mechanische Führungen, beispielsweise Hauben vorgesehen sein, die es erzwingen, daß die Hand eines Benutzers unter die Haube greift, sodaß die für den Schaltvorgang benötigte Hand nicht noch andere Arbeitsvorgänge durchführen kann oder daß der zugehörige Schalter beispielsweise mittels eines Beins oder eines Gegenstandes betätigbar ist. Diese Führungen übergreifen den Schalter.The switches 40 are preferably pressure contacts that are normally spring-loaded in the open position. Only if you the switch is closed. The (electrical) control device is switched so that only when the pressure switches 40 are closed the transition to the pressing position is possible. There are other versions possible. The switches 40 can thus be designed as touch switches be, the pressure switches described can also be pressed in the Open position, the switches can be pneumatic or hydraulic Switch. There can be mechanical guides, for example hoods be provided that force a user's hand under the Hood engages so that the hand required for the switching process is not yet can perform other operations or that the associated switch can be actuated, for example, by means of a leg or an object. These guides overlap the switch.

    Die beiden Schalter 40 sind auch so ausreichend weit voneinander, daß es unmöglich ist, sie mit derselben Hand zu betätigen. Sie müssen auch jedesmal neu betätigt werden, es ist also nicht möglich, einen Schalter permanent zu drücken, beispielsweise durch Überkleben mit einem Klebeband. Vielmehr ist die elektrische Schaltung im Maschinengestell so ausgelegt, daß jedesmal der Schaltvorgang der Schalter 40 abgefragt wird, bevor die Beziehpresse in die Pressposition gebracht werden kann.The two switches 40 are also sufficiently far apart that it it is impossible to operate them with the same hand. You also have to every time to be operated again, so it is not possible to permanently switch a switch to press, for example by sticking over with an adhesive tape. Rather, the electrical circuit in the machine frame is designed so that each time the switching operation of the switch 40 is queried before the Relative press can be brought into the press position.

    Um die Pressmittel 22, 24 aus der Öffnungsposition in die Zwischenposition und später in die Pressposition zu bewegen, sind unterschiedliche Bewegungsabläufe möglich. Es können beide Pressmittel 22, 24 bewegt werden, es genügt aber auch, ein Pressmittel zu bewegen und das andere stationär zu halten. Die Bewegung des mindestens einen Pressmittels 22, 24 kann durch Schwenken und/oder durch Verschieben in Richtung auf das jeweils andere Pressmittel erfolgen. Vorzugsweise sind die Druckstangen 28 lösbar mit den Leisten verbunden, beispielsweise in diese eingeschraubt. Dadurch können unterschiedliche Druckstangen 28 eingesetzt werden. Der Unterschied kann in der Anzahl, der Länge, der Neigung usw. liegen.To the pressing means 22, 24 from the open position to the intermediate position and later moving to the press position are different movements possible. Both pressing means 22, 24 can be moved, it But it is also sufficient to move one press and the other stationary hold. The movement of the at least one pressing means 22, 24 can by Panning and / or by moving towards the other Press media are carried out. The push rods 28 are preferably detachable with the Last connected, for example screwed into this. This allows different push rods 28 are used. The difference can in number, length, inclination, etc.

    Bei der Ausführung gemäß FIG. 5 sind die beiden Schalter 40 im ausreichenden Abstand voneinander an einer Stange 42 angeordnet. Diese ist bewegbar oder lösbar mit einer Schmalseite 38 verbunden, beispielsweise angelenkt. Ein Sicherheitsschalter sorgt vorzugsweise dafür, daß die Vorrichtung nur im gezeigten Zustand, also bei quer von der Schmalseite 38 wegstehender Stange 42 betrieben werden kann.In the execution according to FIG. 5, the two switches 40 are sufficient Spaced from each other on a rod 42. This is movable or releasably connected to a narrow side 38, for example articulated. A safety switch preferably ensures that the device only in the state shown, that is to say transversely from the narrow side 38 standing rod 42 can be operated.
