Description

Die Erfindung betrifft eine Vorrichtung zum Stapeln von vorzugsweise mit Positionierlöchern versehenen flachen Gegenständen, vorzugsweise von von einer Kunststoffschlauch- oder -halbschlauchbahn abgeschweissten Beuteln, die vorzugsweise von einem sogenannten Wicketer mit um eine Achse rotierenden, paarweise angeordneten Transportarmen übergeben werden, bestehend aus einer Stapelstrecke aus endlosen, über Umlenkräder oder -rollen laufenden, intermittierend angetriebenen Zugmitteln, die mit aufragenden, auf Tragplatten befestigten Stapelstiften oder -nadeln versehen sind.The invention relates to a device for stacking flat objects, preferably provided with positioning holes, preferably bags which are welded off by a plastic tube or semi-tube web and which are preferably transferred from a so-called wicketer with transport arms rotating in pairs, arranged in pairs, consisting of a stacking section Endless, intermittently driven traction means running over deflection wheels or rollers, which are provided with upstanding stacking pins or needles attached to support plates.

Bei einer aus der DE-PS 31 38 221 bekannten Vorrichtung dieser Art werden von einem Folienschlauch durch Querschweissnähte abgeschweisste Doppelbeutel auf von endlosen Ketten getragenen Stapelplatten abgelegt, die zur Aufnahme der Beutel beidseits ihrer Längsmittellinie eine Reihe von Stapelstiften aufweisen. Zur Trennung der Beutel ist ein beheiztes heb- und absenkbares Messer vorgesehen, das die in der Schneidstation befindlichen Stapel zwischen den Reihen der Stapelstifte durchtrennt, wobei die Stapelplatte das Widerlager für das Schneidmesser bildet. Da die Stapelplatten zugleich auch die Widerlager für die beheizten Messer bilden, müssen diese relativ gross und schwer ausgebildet werden.In a device of this type known from DE-PS 31 38 221, double bags welded from a film tube by transverse weld seams are placed on stacking plates carried by endless chains, which have a series of stacking pins on both sides of their longitudinal center line for receiving the bags. To separate the bags, a heated knife can be raised and lowered, which cuts the stacks located in the cutting station between the rows of stacking pins, the stacking plate forming the abutment for the cutting knife. Since the stacking plates also form the abutments for the heated knives, these have to be made relatively large and heavy.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs angegebenen Art zu schaffen, die bei einfacherAnpassung an unterschiedliche Formate und wechselnde Bedingungen in einfacher Weise unterschiedliche Arten von Bearbeitungen an den Stapeln zulässt.The object of the invention is to provide a device of the type specified at the outset which, with simple adaptation to different formats and changing conditions, allows different types of processing on the stacks in a simple manner.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass zwei Stapelstrecken vorgesehen sind und dass zwischen den Stapelstrecken wahlweise unterschiedliche Werkzeuge zur Bearbeitung der intermittierend geförderten Stapel austauschbar und gestellfest angeordnet sind.According to the invention, this object is achieved in that two stacking sections are provided and in that, between the stacking sections, different tools for processing the intermittently conveyed stacks are optionally interchangeable and fixed to the frame.

DieAnordnung von zwei Stapelstrecken ermöglicht es, wahlweise zwischen diesen gestellfeste Bearbeitungswerkzeuge anzuordnen, die in beliebiger Weise zusammenwirken können, da es nicht mehr erforderlich ist, als Gegenwerkzeug die intermittierend mitbewegten Stapelplatten miteinzubeziehen. Die beiden Stapelstrecken können entsprechend leichter ausgelegt werden, weil sie nur noch der Stapelung dienen und nicht mehr die Funktion von Gegenwerkzeugen übernehmen müssen.The arrangement of two stacking sections makes it possible to selectively arrange between them processing tools which are fixed to the frame and which can interact in any manner, since it is no longer necessary to include the stacking plates which are moved intermittently as a counter-tool. The two stacking sections can be designed correspondingly lighter because they only serve for stacking and no longer have to take on the function of counter tools.

Die Werkzeuge können aus einem im Bereich der Förderebene angeordneten gestellfesten Widerlager, dessen Länge der Länge der Stapel in Förderrichtung entspricht, und einem beheizten heb- und absenkbaren Schneidmesser entsprechender Länge bestehen, das in gestellfesten Rahmenteilen gelagert ist. Nach dieser Ausgestaltung lassen sich auf den Stapelstrecken gestapelte Doppelbeutel mittig trennen, wobei durch das beheizte Schneidmesser zugleich eine Verblockung der getrennten Stapel an den Schnittflächen erfolgt. Das Schneidmesser und das Widerlager lassen sich nach Bedarf austauschen oder auch gänzlich entfernen.The tools can consist of an abutment fixed to the frame in the region of the conveying plane, the length of which corresponds to the length of the stack in the conveying direction, and a heated lifting and lowering cutting knife of corresponding length, which is mounted in frame parts fixed to the frame. According to this embodiment, double bags stacked on the stacking sections can be separated in the middle, the heated cutting knife simultaneously blocking the separated stacks on the cut surfaces. The cutting knife and the abutment can be exchanged or completely removed as required.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Werkzeuge aus einer gestellfesten Widerlagerplatte und aus auf diese absenkbaren Stanz- oder Haltestempeln und/oder Perforiermesser bestehen. Eine derartige vorzugsweise mit Haltestempeln versehene Widerlagerplatte bietet den Vorteil, dass sie mit Aussparungen versehen werden kann, so dass Bearbeitungswerkzeuge auch unterhalb der Widerlagerplatte angeordnet werden können, die zur Bearbeitung der Stapel durch die Aussparungen treten. Beispielsweise kann also ein beheiztes Schneidmesser zum Durchtrennen der Stapel von unten durch die Widerlagerplatte hindurchtreten.In a further embodiment of the invention, it is provided that the tools consist of an abutment plate fixed to the frame and of punching or holding punches and / or perforating knives which can be lowered thereon. Such an abutment plate, which is preferably provided with holding punches, offers the advantage that it can be provided with cutouts, so that processing tools can also be arranged below the abutment plate, which pass through the cutouts for processing the stack. For example, a heated cutting knife can thus pass through the abutment plate from below for severing the stacks.

Die Zugmittel jeder Stapelstrecke, die vorzugsweise aus Zahnriemen bestehen, können auch mit nur einer Nadel oder einem Stift versehen sein, so dass nach der Trennung der Stapel durch einen Längsschnitt die Stapelhälften, die seitlich über die Stapelstrecken herabhängen, eine Drehung ausführen, wenn die Nadel oder der Stift seitlich, also exzentrisch angeordnet ist. Diese Drehung kann vorteilhaft sein, um die Schnittflächen von dem beheizten Trennmesser wegzubewegen.The traction means of each stacking section, which preferably consist of toothed belts, can also be provided with only one needle or a pin, so that after the stacks have been separated by a longitudinal cut, the stack halves, which hang laterally over the stacking sections, rotate when the needle or the pin is arranged laterally, ie eccentrically. This rotation can be advantageous in order to move the cut surfaces away from the heated cutting knife.

Nach einer erfinderischen Ausgestaltung ist vorgesehen, dass die Längsträger der beiden Stapelstrecken in dem Endgestell auf einer Querachse drehfest um deren horizontale Achse gelagert und in ihrem mittleren oder vorderen Bereich über einen Stempel oder dergleichen auf einem das Endgestell mit dem Wicketergestellverbindenden Träger abgestützt sind, der mit Endgestell biegesteif verbunden und mit seinem vorderen Ende auf einer Querachse des Wicketergestells querverschieblich geführt ist, wobei das Endgestell auf bodenfesten Führungen in Querrichtung verschieblich oder verfahrbar geführt und eine Einrichtung zum Bewegen des Endgestells in Querrichtung vorgesehen ist. Zum Anpassen an unterschiedliche Formate werden beide Stapelstrecken gegeneinander verfahren. Zum Betreiben des Wicketers mit nur einer seitlichen Stapelung werden beide Stapelstrecken gemeinsam seitlich verfahren, und zwar so weit, dass die Stapelstrecken die Wicketerarme einer Seite zwischen sich einschliessen. Zum Betreiben der Vorrichtung mit nur einer seitlichen Stapelung braucht der Werkzeugsatz nicht ausgebaut zu werden, da er die Stapelung nicht beeinträchtigt.According to an inventive embodiment, it is provided that the longitudinal beams of the two stacking sections in the end frame are mounted on a transverse axis in a rotationally fixed manner about their horizontal axis and are supported in their central or front region by a stamp or the like on a carrier connecting the end frame to the winder frame, which supports End frame is rigidly connected and is guided with its front end on a transverse axis of the winding frame, the end frame being guided displaceably or displaceably in the transverse direction on floor-fixed guides and a device for moving the end frame in the transverse direction is provided. To adapt to different formats, both stacking sections are moved against each other. To operate the winder with only one side stacking, both stacking sections are moved laterally together, to the extent that the stacking sections enclose the winder arms on one side between them. The tool set does not need to be removed to operate the device with only one side stack, since it does not impair the stacking.

Nach einer weiteren erfindungsgemässen Weiterbildung ist vorgesehen, dass die Längsträger der Stapelstrecken über mit diesen drehfest verbundene Gleitbuchsen auf der Querachse des Endgestells gelagert und beide Längsträger mit Gewindemuttern mit gegenläufigen Gewinden versehen sind, in die eine gemeinsame querverlaufende Spindelachse zur Verstellung des Abstandes der Stapelstrecken eingeschraubt ist, und dass die Längsträger der Stapelstrecken auf einer von dem Stempel oder dergleichen getragenen Gleitplatte abgestützt sind. Diese Ausgestaltung ermöglicht es, zur Anpassung an unterschiedliche Formate den Abstand der Stapelstrecken auf einfache Weise nur durch Betätigung der Spindel zu ändern.According to a further development according to the invention, it is provided that the longitudinal beams of the stacking sections are mounted on the transverse axis of the end frame via slide bushes connected in a rotationally fixed manner, and both longitudinal beams are provided with threaded nuts with opposing threads into which a common transverse spindle axis is screwed in order to adjust the distance between the stacking sections , and that the longitudinal beams of the stacking sections are supported on a slide plate carried by the stamp or the like. This configuration makes it possible to adapt the spacing of the stacking sections to one in order to adapt to different formats easy to change only by operating the spindle.

Diese seitlich der Stapelstrecken 8, 9 angeordneten Seitenteile dienen der Aufnahme von die Stapel bearbeitenden Werkzeugen.The lower longitudinal member 14, which connects the winder frame 1 to the end frame 10, is provided with lateral base frame parts 41, 42 which are connected to the latter via flanges 40 and which carry side parts 43, 44. These side parts arranged to the side of the stack sections 8, 9 serve to hold tools that process the stack.

Bei dem Ausführungsbeispiel nach den Fig. 1 bis 3 ist auf den unteren Längsträger 14 ein Widerlager 45 aufgeschraubt, das mit die Schrauben aufnehmenden bodenseitigen Flanschen 46, 47 versehen ist. Die Oberseite des Widerlagers 45 ist zur Polsterung mit einer ausreichend wärmebeständigen Kunststoffleiste 48 versehen. Die Oberseite dieser Leiste 48 liegt im Bereich der Förderebene der von Platten 49 getragenen Stapelstifte 50. Die die Stapelstifte 50 tragenden Platten 49 sind abwechselnd mit paarweise parallel umlaufenden Zahnriemen 51, 52 verbunden.In the exemplary embodiment according to FIGS. 1 to 3, an abutment 45 is screwed onto the lower longitudinal member 14 and is provided with the bottom flanges 46, 47 receiving the screws. The top of the abutment 45 is provided with a sufficiently heat-resistant plastic strip 48 for padding. The top of this strip 48 lies in the region of the conveying plane of the stacking pins 50 carried by plates 49. The plates 49 carrying the stacking pins 50 are alternately connected to toothed belts 51, 52 which run in parallel and in pairs.

An den Seitenteilen 43, 44 ist heb- und senkbar das beheizte Schneidmesser 53 angeordnet, das zwischen den Stapelstiften 50 die Stapel durchtrennt.On the side parts 43, 44, the heated cutting knife 53 can be raised and lowered and cuts the stacks between the stacking pins 50.

Bei dem Ausführungsbeispiel nach Fig. 4 ist eine gestellfeste Widerlagerplatte 55 vorgesehen, die mit einer mittleren Aussparung 56 versehen ist. Oberhalb der Widerlagerplatte 55 sind an den Seitenteilen 43, 44 absenkbare Haltestempel 57 und Perforiermesser 58 angeordnet. Unterhalb der Widerlagerplatte ist ein heb- und senkbares beheizbares Schneidmesser 59 angeordnet, das durch die Aussparung 56 greift. Nach Absenken der Haltestempel 57 lässt sich somit ein auf der Widerlagerplatte 50 liegender Stapel durch Heben des unteren Messers 59 durchtrennen.In the exemplary embodiment according to FIG. 4, an abutment plate 55 which is fixed to the frame and is provided with a central recess 56 is provided. Above the abutment plate 55, lowerable holding punches 57 and perforating knives 58 are arranged on the side parts 43, 44. Arranged below the abutment plate is a heatable cutting knife 59 which can be raised and lowered and which extends through the recess 56. After the holding punches 57 have been lowered, a stack lying on the abutment plate 50 can thus be severed by lifting the lower knife 59.

Bei dem Ausführungsbeispiel nach Fig. 4 sind auf den Zahnriemen befestigten Platten 60 Nadeln 61 befestigt, auf die sich von den Tragarmen 5 die Beutel ohne vorherige Anbringung von Positionierlöchern aufnadeln lassen.In the embodiment according to FIG. 4, plates 60 attached to the toothed belt are attached to needles 61, onto which the bags can be needled by the support arms 5 without prior positioning holes.

Ist jeweils exzentrisch, also aussermittig, nur eine Nadel 61 angebracht, schwenken die von diesen gehaltenen geteilten Stapel nach dem Durchtrennen mit dem beheizten Trennmesser 59, so dass die verblockten Schnittflächen von dem Schneidmesser 59 fortbewegt werden.If only one needle 61 is attached eccentrically, that is to say off-center, pivot the needle sen kept divided stack after cutting with the heated cutting knife 59, so that the blocked cutting surfaces are moved by the cutting knife 59.
