Definitions
- the invention relates to a closure arrangement according to the preamble of the independent claim.
- the object of the present invention is to improve a closure arrangement for closure clips.
- the feed lever has a plastic support at its front end or feed end or is formed from plastic, or has a roller or ball
- the clip wire can be spared during feed.
- the wear of the closing arrangement itself is greatly reduced when this arrangement is in idle mode without clip wire in operation, since doing the feed end the feed lever comes into contact with the clip wire guide in the feed channel.
- a plastic training or a rotatable role or ball-like training can significantly reduce the wear of the arrangement in this area.
- a wire positioning and wire retention means is provided in the feed channel itself increases the positioning accuracy of the clip wire in the cutting and forming tool and avoids incorrect positioning due to the behavior of the wire, especially at high cadences of the arrangement.
- Another aspect is the adjustability of the die on the forearm of the closure arrangement, which allows the adjustment of the cutting clearance and thus the correct clip formation in a simple manner.
- FIG. 1 shows a closing arrangement 100 according to the prior art, by means of which the essential elements of a closing arrangement will be briefly explained again.
- a die 118 Disposed on a forearm 116 of such an assembly is a die 118 which, together with a punch 117 on an upper arm 115 (shown in broken lines), forms a clip cutting and sealing tool consisting of a continuous preformed clip wire 112 and 112, respectively be formed.
- the clip wire feed takes place by a feed lever 113 which is rotatably mounted on a crank disk 114 and pivots in the movement in the arrow direction about the pin 119 and performs with its front free end the indicated egg-shaped movement.
- the scissors lace in a known manner in closely adjacent position, the package by a movement of the scissor arms and then move away from each other, which forms an elongated, constricted, product-free area of the packaging material (sausage casing) between the two sausages, in which then in the Usually two clips are set in succession, namely the end clip of one sausage-shaped package and the initial clip of the subsequent sausage-shaped package.
- various drive elements which achieve the said movements for constricting, cutting and closing by a motor drive with chains, gears and cams. this will here, as known, not explained further.
- the present invention relates to such a closure arrangement as far as not explained below.
- FIG. 2 now shows a more detailed, partially sectioned representation of an inventive closure arrangement, wherein in FIG. 2 only the lower arm 2 and the wire feed is shown and the punch 4 is indicated, while the other elements, in particular the shears of the closing arrangement are not shown.
- the clip wire 5 is also shown here as a preformed clip wire in the position in which it lies in the die 3 and is positioned for cutting between the cutting parts 37 and 38 of punch 4 and die 3.
- the feed of the clip wire is carried out with a feed lever 11 in a known manner by this is fixed to a crank disc 12, which will be explained in more detail, and rotates about the pin 16 and moves along it.
- the clip wire 5 is guided in a feed channel 6 with an upper part 20, in which feed channel, the front free end of the feed lever engages from below to move the clip wire in each case by a clip division forward and in the die 3 as shown position.
- the clip wire 5 comes from a clip wire supply, not shown, which is usually a clip wire roller, which is rotatably supported on the Verschliessan extract and from which the clip wire is inserted in a manner not shown in the feed channel 6.
- the feed channel 6 is seated on a support 7 which is rotatable about the axis 8 for lifting the feed channel and thus the clip wire 5, so that the clip wire 5 can be lifted over the blade 38 during the advance and then lowered into the die.
- the feed channel 6 with its carrier 7 is raised during the advance by the feed lever 11, 11 'against the force of a spring 10 and the feed of the Wire causes.
- the spring force on the other hand leads to lowering of the feed channel 6 and the clip wire 5 when the feed lever 11 is moved by the crank mechanism 12, 13 back down.
- a cutting positioning means 24 engaging outside the feed channel at the top of the clip wire is known.
- FIG. 3 shows a section through the feed drive along the line AA of FIG. 2 , Based on Figures 2 and 3 Now, a first aspect of the invention can be explained. Accordingly, the front free end of the feed lever 11, which acts on the clip wire and causes the lifting of the feed channel is formed in the example shown by a substantially U-shaped plastic cap 17, which forms the free end of the feed lever 11 and the feed end, which engages the clip wire 5. Side of this plastic cap 17, the free tongues 22 and 23 of the feed lever are visible, which, however, do not promote the wire but only form a lateral guide for this.
- the formation of the front, the wire conveying end of the feed lever 11 made of plastic on the one hand has the advantage that the wire over the previous purely metallic design of the feed lever during feeding is not damaged and is not provided with engagement marks.
- Another significant advantage is that the front part of the feed lever dips less far into the clip wire through its cap 17.
- the - depending on the pitch of the clip wire - deep immersion of the feed lever according to the prior art can namely lead to a temporary jamming of the front part in the wire, which interferes with its exact promotion and positioning.
- the main advantage lies in the fact that at idle the machine without wire, which may happen at the end of the wire coil and also otherwise, the upper wire guide in the feed channel 6 is not damaged. This is in FIG.
- the upper guide 21 consists of a material to which the wire 5 in its promotion despite the force of the spring 10 easily slides along to provide as low as possible promotion even at high cadences. It is known, for example, to manufacture the upper guide 21 from bronze in order to give a good sliding behavior for an aluminum wire 5. In the embodiment of the feed lever 11 and the front end of the prior art made of metal, it comes at idle wire without a considerable wear on the guide 21 which is undesirable. This is remedied according to the first aspect of the invention, in that the plastic part 17 does not wear the guide 21 even when idling, so that its service life is substantially increased.
- the whole front part of the feed lever 11 may be integrally formed of plastic, in particular together with the tongues 22 and 23. Further embodiments are possible, for example, by the front engaging end of the feed lever 11 of a cylindrical, rotatable about its longitudinal axis Feed lever 11 arranged roll is formed, which can also engage in the wire 5 to its promotion and which rolls at low wear on the upper guide 21 wear. Instead of a roller and the provision of a front end of the feed lever 11 with a held in a holder and partially exposed ball is possible, which rolls on idle operation on the guide 21.
- the structurally simple and cost-effective solution with the plastic part 17 is preferred.
- Another aspect of the invention lies in the attachment of the feed lever 11 on the crank mechanism.
- the feed lever must be replaced for different widths of the clip wire to be adjusted in its width also to this, due to the lateral Tongues 22 and 23 can be seen which form lateral guides for the clip wire.
- the feed lever must be unscrewed from the driven crank pulley 12 by the threaded bearing pin of the feed lever is attached to the disc is released and is fixed again for the new feed lever. This work is complicated due to the installation position of the crank mechanism.
- the feed lever 11 is attached to the crank mechanism so that it can be attached and detached without tools.
- a tensile force on the feed lever is exerted in such a way that the side parts of the support member 14 spread open again, so that the pin can be solved.
- This type of assembly results in a very quick and easy tool-releasable mounting option.
- the holding member 14 may be fastened with screws on the central part of the feed lever 11, like that FIG. 3 is apparent.
- a circumferentially extending recess may be present, in which a corresponding shape of the retaining element 14 can engage to exact positioning in the longitudinal direction of the pin 13 to to reach.
- a wire positioning and retaining means 25 is arranged in the feed channel, which prevents sliding back of the wire during and after its feed. It is known to provide a partially out of the feed channel wire holding means 24, which contacts the wire only outside the feed channel and presses against the cutting edge 38 of the die 3 to improve the cutting precision. However, it has been shown that at high cadences or wire feed speeds inaccuracies in the wire positioning and cutting may occur to which the wire holding means 24 has no significant influence. To prevent them, a positioning and retaining means is now provided, which engages in the feed channel 6 on the wire and prevents it from sliding back.
- the wire retaining means in the feed channel can effectively prevent this and improve the positioning precision of the wire and thus the good quality of the closure clip.
- the wire retaining means is arranged in the feed channel in the conveying direction in front of the feed lever 11, so that the wire thus first reaches the wire retaining means and then the feed lever, as shown in the FIG. 2 is shown.
- the means 25 contacts the wire from below and is also arranged on the lower inside of the feed channel.
- the wire retaining means and positioning means 25 may be formed in any way, but it should impede the feed of the wire as little as possible, while preventing the sliding back of the wire against the feed direction as effectively as possible.
- a preferred construction for this is in FIG. 2 shown, in which the wire retaining means is formed by a lying on the underside of the feed channel 6 leaf-shaped spring which is fixed in the feed channel and can bend in the advance of the wire in the figure down and thus does not hinder the feed, but which springs back when it is no longer acted upon by the wire and has a front bearing surface 25 ', which prevents sliding back of the wire against the conveying direction.
- the spring force is made adjustable. This can be done in a simple manner initially as shown in the figure, characterized in that the spring attached to the lower arm and the holder 7 of the feed channel is arranged at one or both of these points so that the bias of the spring can be adjusted. In the in the FIG. 2 shown embodiment, this is achieved in a simple manner such that the spring 10 is held on the forearm side to a threaded bolt 26 which is adjustable by a nut 27 so that the spring preload can be adjusted by turning the nut 27.
- Another aspect of the invention relates to the attachment of the die 3 on the forearm 2. This is done in such a way that the die 3 is displaceable in the feed direction or against the feed direction, whereby the cutting clearance x between the cutting edges 37 and 38 about 5/100 mm should be adjustable to the die 3 itself. This was not the case until now and due to the tolerances between the forearm and the upper arm supporting the punch 4, the cutting clearance often had to be very large.
- the adjustability of the die now gives the opportunity to adjust the cutting clearance with fully assembled closure assembly.
- an eccentric pin 30 is arranged in a bore of the lower arm and rotatable there, wherein the protruding from the bore upper part of the eccentric pin 30 performs an eccentric movement.
- the die 3 is as in FIG.
- the die 3 is as in FIG. 4 indicated with a transverse slot 34, in which the eccentric part of the pin 30 engages so that the die is defined defined in its position in the feed direction upon rotation of the pin 30 in its bore by the eccentric.
- This allows the exact adjustment of the cutting clearance by displacement of the die 3 in the final assembled Verschliessan extract and thus the compensation of the tolerances between the forearm and upper arm. Is the cutting game set accordingly, the die 3 can be fixed by the threaded bolt 31 definitely on the forearm 2.

Description
Die Erfindung betrifft eine Verschliessanordnung gemäss dem Oberbegriff des unabhängigen Patentanspruchs.The invention relates to a closure arrangement according to the preamble of the independent claim.
Es ist bekannt, Verpackungen durch Metallclipse zu verschliessen, wobei solche Verpackungen z.B. wurstförmige Verpackungen sind, die aus einer Füllmaschine austreten und von der Verschliessanordnung mit Clipsen versehen werden. Bei der Bildung von Würsten, die als kontinuierliches, schlauchförmiges Produkt aus einer Füllmaschine austreten, weist die Verschliessanordnung in der Regel Verdrängerscheren auf, die die Einschnürung zwischen dem Ende der einen Wurst und dem Anfang der nächsten Wurst bilden, bei welcher Einschnürung der Clip für das Ende der einen Wurst und der Clip für den Anfang der nächsten Wurst gesetzt wird. Die Clips werden dabei von einem kontinuierlichen, vorgeformte offene Clipse aneinander anschliessend bildenden Clipdraht, der in der Regel in Rollenform an der Verschliessanordnung gehalten ist, beim Setzen des Clips abgeschnitten und zum geschlossenen Clip verformt. Solches ist z.B. aus
Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine Verschliessanordnung für Verschlussclipse zu verbessern.The object of the present invention is to improve a closure arrangement for closure clips.
Diese Aufgabe wird mit den Verschliessanordnungen gemäss Anspruch 1 gelöst. Dass der Vorschubhebel antriebsseitig werkzeuglos lösbar und wieder befestigbar ist, reduziert die Standzeiten der Anordnung beim Wechsel des Vorschubhebels für verschiedene Clipdrahtbreiten ganz erheblich.This object is achieved with the closure arrangements according to
Dadurch, dass vorzugsweise der Vorschubhebel an seinem Vorderende bzw. Vorschubende eine Kunststoffauflage aufweist oder aus Kunststoff gebildet ist, oder eine Rolle oder Kugel aufweist, kann einerseits der Clipdraht beim Vorschub geschont werden. Andererseits wird aber besonders der Verschleiss der Verschliessanordnung selber stark gemindert, wenn diese Anordnung im Leerlaufbetrieb ohne Clipdraht in Betrieb ist, da dabei das Vorschubende des Vorschubhebels mit der Clipdrahtführung im Vorschubkanal in Kontakt kommt. Eine Kunststoffausbildung oder eine drehbare rollen- oder kugelartige Ausbildung kann in diesem Bereich den Verschleiss der Anordnung deutlich vermindern.Because preferably the feed lever has a plastic support at its front end or feed end or is formed from plastic, or has a roller or ball, on the one hand the clip wire can be spared during feed. On the other hand, but especially the wear of the closing arrangement itself is greatly reduced when this arrangement is in idle mode without clip wire in operation, since doing the feed end the feed lever comes into contact with the clip wire guide in the feed channel. A plastic training or a rotatable role or ball-like training can significantly reduce the wear of the arrangement in this area.
Dass neu im Vorschubkanal selber ein Drahtpositionierungs- und Drahtrückhaltemittel vorgesehen ist, erhöht die Positioniergenauigkeit des Clipdrahtes im Schneid- und Formwerkzeug und vermeidet besonders bei hohen Kadenzen der Anordnung Fehlpositionierungen aufgrund des Verhaltens des Drahtes.The fact that a wire positioning and wire retention means is provided in the feed channel itself increases the positioning accuracy of the clip wire in the cutting and forming tool and avoids incorrect positioning due to the behavior of the wire, especially at high cadences of the arrangement.
Ebenfalls für eine gute Drahtpositionierung besorgt ist die Einstellbarkeit der Federkraft, die auf den Vorschubkanal wirkt.Also concerned about good wire positioning is the adjustability of the spring force acting on the feed channel.
Ein weiterer Aspekt ist die Justierbarkeit der Matrize am Unterarm der Verschliessanordnung, welche auf einfache Weise die Einstellung des Schnittspiels und damit die korrekte Clipbildung ermöglicht.Another aspect is the adjustability of the die on the forearm of the closure arrangement, which allows the adjustment of the cutting clearance and thus the correct clip formation in a simple manner.

Die
Ein weiterer Aspekt der Erfindung liegt in der Befestigung des Vorschubhebels 11 am Kurbeltrieb. Der Vorschubhebel muss für verschiedene Breiten des Clipdrahtes ausgewechselt werden, um in seiner Breite ebenfalls an diese angepasst zu sein, was aufgrund der seitlichen Zungen 22 und 23 ersichtlich ist, die seitliche Führungen für den Clipdraht bilden. Nach Stand der Technik muss der Vorschubhebel von der angetriebenen Kurbelscheibe 12 losgeschraubt werden, indem der Gewindelagerbolzen der den Vorschubhebel an der Scheibe befestigt gelöst wird und für den neuen Vorschubhebel wieder befestigt wird. Diese Arbeit ist aufgrund der Einbaulage des Kurbeltriebes aufwendig. Gemäss der vorliegenden Erfindung wird der Vorschubhebel 11 am Kurbeltrieb so befestigt, dass er werkzeuglos an diesem befestigt und gelöst werden kann. Dies ist grundsätzlich durch jedes werkzeuglos montierbare und wieder lösbare Befestigungsmittel möglich, das die entsprechend bewegliche Halterung des Vorschubhebels 11 an der Kurbelscheibe 12 ermöglicht. Besonders bevorzugt ist die dargestellte Ausführungsform, bei welcher an der Kurbelscheibe 12 ein abstehender Zapfen 13, 13' fest angeordnet ist. An dem Vorschubhebel andererseits ist eine entsprechende, zum Zapfen 13 passende Klemmanordnung 14 vorgesehen, z.B. aus Kunststoff, welche durch elastisches federndes Umgreifen des Zapfens 13 um einen grösseren Teil seines Umfanges auf den Zapfen 13' aufclipbar ist. Mit anderen Worten, bei einer Montagebewegung, welche den Vorschubhebel 11 auf den Zapfen 13 aufdrückt, werden die beiden Seitenteile der Befestigung 14 federnd auseinander gedrückt, so dass der Zapfen in die entsprechend geformte Ausnehmung im Halteteil 14 hineingedrückt wird. Die beim Hineindrücken aufgespreizten Seitenteile des Halteelements 14 gehen dabei wieder in ihre Ausgangslage zurück und halten den Vorschubhebel drehbar auf dem Zapfen 13. Zur Demontage wird eine Zugkraft auf den Vorschubhebel derart ausgeübt, dass sich die Seitenteile des Halteelements 14 wieder aufspreizen, so dass der Zapfen gelöst werden kann. Diese Art der Montage ergibt eine sehr rasche und einfache werkzeuglos lösbare Befestigungsmöglichkeit. Das Halteelement 14 kann dabei mit Schrauben am Mittelteil des Vorschubhebels 11 befestigt sein, wie das aus
Gemäss einem weiteren Aspekt der Erfindung ist im Vorschubkanal ein Drahtpositionier- und -rückhaltemittel 25 angeordnet, welches ein Zurückgleiten des Drahtes bei und nach dessen Vorschub verhindert. Bekannt ist es, ein teilweise ausserhalb des Vorschubkanals liegendes Drahthaltemittel 24 vorzusehen, welches den Draht nur ausserhalb des Vorschubkanals kontaktiert und diesen gegen die Schneide 38 der Matrize 3 drückt, um die Schnittpräzision zu verbessern. Es hat sich aber gezeigt, dass bei hohen Kadenzen bzw. Drahtvorschubgeschwindigkeiten Ungenauigkeiten bei der Drahtpositionierung und beim Schnitt vorkommen können, auf die das Drahthaltemittel 24 keinen wesentlichen Einfluss hat. Zu deren Verhinderung wird nun ein Positionier- und Rückhaltemittel vorgesehen, welches im Vorschubkanal 6 am Draht angreift und dessen Zurückgleiten verhindert. Dieses kann erfolgen, da die Drahtrolle und der vorgeformte Draht auf seinem Weg bis zur Matrize eine erhebliche, insbesondere durch die Vorformung bewirkte Elastizität in Vorschubrichtung besitzen, welche zu Schwingungen und anderen Effekten führen kann, die das präzise Vorschieben durch ein Zurückgleiten des Drahtes beeinträchtigen können. Das Drahtrückhaltemittel im Vorschubkanal kann dies wirksam verhindern und die Positionierungspräzision des Drahtes und damit die qualitativ gute Ausbildung des Verschlussclips verbessern. Bevorzugterweise ist das Drahtrückhaltemittel im Vorschubkanal in Förderrichtung vor dem Vorschubhebel 11 angeordnet, so dass der Draht also zunächst das Drahtrückhaltemittel erreicht und danach den Vorschubhebel, wie dies in der
Ein weiterer Aspekt zur Beeinflussung der Positionierungsgenauigkeit und damit der Qualität des Clipverschlusses besteht in der Beeinflussung der Kraft der Feder 10. Nach Stand der Technik ist diese Federkraft nicht einstellbar und wird für alle Drahtdimensionen und Kadenzen gleich gewählt. Gemäss dem nun erläuterten Aspekt der Erfindung wird dahingegen die Federkraft einstellbar gemacht. Dies kann auf einfache Weise zunächst wie in der Figur gezeigt dadurch erfolgen, dass die am Unterarm und an der Halterung 7 des Vorschubkanals befestigte Feder an einer oder beiden dieser Stellen so angeordnet wird, dass die Vorspannung der Feder eingestellt werden kann. In der in der
Ein weiterer Aspekt der Erfindung betrifft die Befestigung der Matrize 3 am Unterarm 2. Diese erfolgt derart, dass die Matrize 3 in Vorschubrichtung bzw. gegen die Vorschubrichtung verschiebbar ist, wodurch das Schnittspiel x zwischen den Schneiden 37 und 38 das ca. 5/100 mm betragen sollte an der Matrize 3 selber einstellbar ist. Dies war bis anhin nicht der Fall und aufgrund der Toleranzen zwischen Unterarm und dem den Stempel 4 tragenden Oberarm musste das Schnittspiel häufig sehr gross gewählt werden. Die Verstellbarkeit der Matrize ergibt nun die Möglichkeit das Schnittspiel bei fertig montierter Verschliessanordnung einzustellen. Bevorzugterweise ist dazu ein Exzenterbolzen 30 in einer Bohrung des Unterarms angeordnet und dort drehbar, wobei der aus der Bohrung herausragende obere Teil des Exzenterbolzens 30 eine exzentrische Bewegung ausführt. Die Matrize 3 ist dabei wie in
