Abstract

1. Process for gluing and pressing carton blanks, according to which the carton blanks are glued, are aligned, are pressed and are transported to a subsequent processing station, characterised in that the carton blanks (27, 27', 27") provided with glue are supplied to a collector station formed as conveying means (23 - 26, 30) variable in height, are positioned directly one above the other at continuously or stepwise adjustable limiting stops (28) on the worktable (22) and are pressed onto the conveying means by holding-down elements (46) so that the pressed glue folder spots will not release, that subsequent to having arranged a predetermined number of stacked carton blanks the conveying means (23 - 26, 30) are operated and the stack of carton blanks (27, 27', 27") is moved on the conveying means, that dependent on the movement of the conveying means the carton blanks subsequent to their arriving at the pressing station (2) are automatically pressed, and that after completing the pressing operation the pressed blanks are automatically removed from the machine by the conveying means.

Description

Die Erfindung bezieht sich auf ein Verfahren zum Bekleben und Pressen von Kartonteilen, bei dem die Kartonteile beleimt, ausgerichtet, gepreßt und an eine weitere Verarbeitungsstation transportiert werden, auf eine Einrichtung zum Bekleben und Pressen von Kartonteilen in Form von Kartonzuschnitten, z.B. Displays, mit mindestens einer Klebestation für die Klebestellen der Kartonzuschnitte, einer Transportvorrichtung und einer Preßstation zum Verpressen der Klebestellen, sowie auf eine Positioniervorrichtung für Kartonzuschnitte oder dergl.The invention relates to a method for gluing and pressing cardboard parts, in which the cardboard parts are glued, aligned, pressed and transported to a further processing station, to a device for gluing and pressing cardboard parts in the form of cardboard blanks, e.g. Displays, with at least one gluing station for the gluing points of the cardboard blanks, a transport device and a pressing station for pressing the gluing points, and on a positioning device for cardboard blanks or the like.

Aus der DE-OS 25 50 607 ist ein Verfahren zum Einführen von preßgut in eine Etagenheizpresse bekannt, bei dem die zu pressenden Teile einer Transportvorrichtung zugeführt werden, die aus einzelnen übereinander angeordneten Bandförderern besteht, deren jeder ein einzelnes Teil aufnimmt. Die einzelnen Bandförderer übergeben die Teile getrennt und unabhängig voneinander an die Presse. Das Verpressen der Teile kann ebenso wie das Abtransportieren selbsttätig durchgeführt werden.From DE-OS 25 50 607 a method for introducing material to be pressed into a deck heating press is known, in which the parts to be pressed are fed to a transport device which consists of individual belt conveyors arranged one above the other, each of which accommodates a single part. The individual belt conveyors transfer the parts to the press separately and independently of one another. The pressing of the parts as well as the removal can be carried out automatically.

Des weiteren sind aus der US-PS 4.108.031 Anschläge zum Positionieren von zu bearbeitenden Teilen bzw. Werkstücken bekannt, wobei ein Ausrichten der gestapelten Teile an einer als Anschlag wirkenden Säule erfolgt.Furthermore, from US Pat. No. 4,108,031, stops for positioning parts or workpieces to be machined are known, the stacked parts being aligned on a column acting as a stop.

Bisher werden Kartonagen, die zu Displays, Aufstellern oder dergl. zusammengefügt werden, und die mit anderen Teilen und untereinander verklebt werden müssen, von Hand in eine mechanische Klebevorrichtung eingeführt, einzeln verklebt, manuell wieder hieraus entnommen, einzeln gepreßt und dann einzeln abgelegt. Insbesondere bei kleineren Aufträgen und Stückzahlen erfolgt das Kleben und Pressen von Hand, weil keine Maschinen vorhanden sind, die es gestatten, geringe Stückzahlen wirtschaftlich zu verkleben und zu verpressen.So far, cardboard boxes, which are put together to form displays, stands or the like, and which have to be glued to other parts and to one another, are inserted by hand into a mechanical adhesive device, individually glued, manually removed therefrom, individually pressed and then individually deposited. Especially for small orders and quantities, gluing and pressing is done by hand because there are no machines available that allow small quantities to be glued and pressed economically.

Aufgabe der Erfindung ist es, das Kleben und Verpressen von Kartonagen auch für Kleinserien wirtschaftlich zu gestalten und nach dem Einlegen der mit Klebstoff versehenen Kartonteile den Weitertransport und den Preßvorgang automatisch ablaufen zu lassen. Insbesondere soll mit vorliegender Erfindung erreicht werden, daß das Umstellen bzw. Einstellen der Einrichtung auf unterschiedliche Abmessungen der Kartonzuschnitte für den automatischen Betrieb einfach und schnell mit minimalem Aufwand möglich ist.The object of the invention is to make the gluing and pressing of cardboard boxes economical even for small series and to allow the further transport and the pressing process to take place automatically after inserting the cardboard parts provided with adhesive. In particular, it is to be achieved with the present invention that the changeover or adjustment of the device to different dimensions of the carton blanks for the automatic operation is simple and quick with minimal effort.

Diese Aufgabe wird gemäß der Erfindung mit einem Verfahren mit den Merkmalen des Kennzeichens des Anspruches 1, mit einer Einrichtung mit den Merkmalen des Kennzeichens des Anspruches 2 und mit einer Positioniervorrichtung mit den Merkmalen des Kennzeichens des Anspruches 9 erreicht. Weitere Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Unteransprüche.This object is achieved according to the invention with a method with the features of the characterizing part of claim 1, with a device with the features of the characterizing part of claim 2 and with a positioning device with the features of the characterizing part of claim 9. Further embodiments of the invention are the subject of the dependent subclaims.

Die Vielseitigkeit der Anwendung und die rationelle Arbeitsweise der Einrichtung nach vorliegender Erfindung ergeben sich insbesondere dadurch, daß der Aufnahmetisch relativ zur Transportvorrichtung höhenverstellbar ausgebildet ist, daß die positioniervorrichtung und die Presse als Ganzes höhenverstellbar sind, so daß eine Anpassung an automatische Zuführeinrichtungen vorgenommen werden kann, daß der Übergang der auf dem Aufnahmetisch befindlichen (mit Klebstoff versehenen) Kartonteile in die presse vollautomatisch erfolgen kann, und daß die positionierung der Kartonteile durch auf dem Arbeitstisch stufenlos verschiehbare und festlegbare Anschläge auf einfachste Weise erreichbar ist, so daß eine Einstellung auf unterschiedliche Dimensionen von unterschiedlichen Kartonzuschnitten lediglich durch Verschieben der Begrenzungsanschläge erzielt werden kann. Hierfür eignen sich besonders Magnetanschläge, die auf dem Aufnahmetisch stufenlos verschiebbar und unabhängig von Führungen und dergl. an jeder beliebigen Stelle des Aufnahmetisches einsetzbar sind. Als zweckmäßig hat sich insbes. herausgestellt, die Magnetanschläge mit Niederhaltern zu versehen, die ein einwandfreies, nachgiebig elastisches Andrücken der Kartonteile gegen die Transportvorrichtung ergeben, so daß ein Sichaufrichten der Kartonteile und damit ein Lösen der Klebestellen unmittelbar nach dem Klebstoffauftrag verhindert wird. Des weiteren hat sich als zweck-mäßig herausgestellt, die gesamte Einrichtung fahrbar und damit ortsunabhängig auszubilden.The versatility of use and the efficient operation of the device according to the present invention result in particular from the fact that the receiving table is designed to be height-adjustable relative to the transport device, that the positioning device and the press as a whole are height-adjustable, so that adaptation to automatic feed devices can be carried out. that the transition of the cardboard parts located on the receiving table (provided with adhesive) into the press can be carried out fully automatically, and that the positioning of the cardboard parts can be reached in the simplest way by means of infinitely adjustable and fixable stops on the work table, so that an adjustment to different dimensions of different cardboard blanks can only be achieved by moving the limit stops. Magnetic stops are particularly suitable for this purpose, which can be moved continuously on the receiving table and can be used at any point on the receiving table, independently of guides and the like. It has proven to be particularly expedient to provide the magnetic stops with hold-down devices which result in a perfect, resiliently elastic pressing of the cardboard parts against the transport device, so that a straightening of the cardboard parts and thus a loosening of the adhesive points is prevented immediately after the adhesive application. Furthermore, it has proven to be expedient to design the entire facility to be mobile and therefore independent of location.

  • 2 is a view of the positioning device from the front,
  • Fig. 3 shows a magnetic stop according to the invention, namely
  • Fig. 3a in side view, Fig. 3b in end view and Fig. 3c in supervision.

Die erfindungsgemäße Einrichtung besteht im Prinzip aus einer Positioniervorrichtung 1 und einer Presse 2. Beide haben einen gemeinsamen Rahmen 3, der auf Rädern 4, 5 fahrbar ausgebildet ist. Im betrieb ist die gesamte Einrichtung aufgebockt. Die Winden hierfürsind mit 6, 7, 8 bezsichnet. Sie können in beliebiger Weise ausgestaltete Hubvorrichtungen sein, z.B. mechanisch, pneumatisch oder hydraulisch betätigbar, heber, die stufenlos oder in Stufen höhenverstellbar sind. Der Rahmen 3 besteht aus die Vorrichtungen 1 und 2 aufnehmenden vertikalen und horizontalen Trägern, z.B. l-Trägern, Vierkantrohren oder dgl., nämlich den horizontalen Trägern 9, 10, 11, den horizontalen Querträgern 12, 13, 14, 15, 16 und den vertikalen Trägern 17, 18, 19, 20. Die Positioniervorrichtung 1 weist einen höhenverstellbaren Tisch 22 auf, der über mit dem Rahmen 2 verbunden, mechanische Winden bzw. Hubzylinder 21, welche hydraulisch oder pneumatisch betätigbar sind, stufenlos oder in Stufen abgesenkt und angehoben werden können. Über dem Tisch 22 sind auf dem Träger 13 bzw. mit diesem Träger 13 verbunden Rollen 23, 24, 25, 23', 24', 25' aufgenommen, die zur Führung und zum Antrieb von Transportbändern bzw. Transportriemen 26 oder entsprechenden Transportvorrichtung dienen, deren oberes Trum die Aufnahmefläche für die Kartonteile 27, 27', 27" darstellt, welche übereinander zu einem Stapel angeordnet werden und zwar entweder von Hand oder selbsttätig, z.B. durch stufenweises Absenken des Tisches 20, so daß die Oberseite des Stapels stets die gleiche Höhenlage einnimmt. Der Tisch 22, dessen Oberfläche vorzugsweise sus Metall besteht, dient als Aufnahmefläche für die Anschläge 28, die vorzugsweise als Magnetanschläge ausgebildet und im einzelnen in Fig. 3 dargestellt sind. Diese Anschläge 28 dienen zum exakten Positionieren und Niederhalten der auf der Transportvorrichtung 26 zu stapelnden Kartonteile 27.The device according to the invention consists in principle of a positioning device 1 and a press 2. Both have a common frame 3, which is designed to be mobile on wheels 4, 5. The entire facility is jacked up in operation. The winches for this are designated 6, 7, 8. They can be lifting devices designed in any way, for example mechanically, pneumatically or hydraulically actuated, lifters which are infinitely variable or adjustable in steps. The frame 3 consists of the devices 1 and 2 receiving vertical and horizontal beams, for example l-beams, square tubes or the like, namely the horizontal beams 9, 10, 11, the horizontal cross beams 12, 13, 14, 15, 16 and vertical supports 17, 18, 19, 20. The positioning device 1 has a height-adjustable table 22 which is connected to the frame 2 by mechanical winches or lifting cylinders 21 which are hydraulic or can be operated pneumatically, can be lowered or raised continuously or in stages. Above the table 22, rollers 23, 24, 25, 23 ', 24', 25 'are received on the carrier 13 or connected to this carrier 13, which serve to guide and drive conveyor belts or conveyor belts 26 or corresponding transport devices, whose upper run represents the receiving surface for the cardboard parts 27, 27 ', 27 ", which are arranged one above the other to form a stack, either by hand or automatically, for example by gradually lowering the table 20, so that the top of the stack is always at the same height The table 22, the surface of which is preferably made of metal, serves as a receiving surface for the stops 28, which are preferably designed as magnetic stops and are shown in detail in Fig. 3. These stops 28 serve for the exact positioning and holding down of those on the transport device 26 Cardboard parts to be stacked 27.

Die Kartonteile 27 werden als Kartonzuschnitte 27a über eine an sich bekannte Klebevorrichtung 29 geführt, wo sie an den Klebestellen mit Klebstoffauftrag versehen werden. Die Zuführung der Kartonteile auf die Transportvorrichtung 26 erfolgt im Falle des Ausführungsbeispieles von Hand, kann aber in entsprechender Weise auch automatisch erfolgen. Hierbei werden die Kartonteile so über die Klebevorrichtung 29 geführt, daß die Klebestellen mit Klebstoff bestrichen und an den vorgegebenen Falzstellen mit dem gefalzten Teil durch Andrücken verbunden werden. Die so vorläufig verklebten Kartonteile 27, 27', 27" werden übereinander gestapelt, dabei exakt aufeinander ausgerichtet und mit Hilf, der Transportvorrichtung 23 bis 26 als gemeinsamer, ausgerichteter Stapel in die Presse 2 übergeführt, indem sie dort von einer Transportvorrichtung 30 übernommen und unter der Preßplatte 31 verpreßt werden. Die Transportvorrichtung 30 der Presse ist beispielsweise ebenfalls als Bandförderer ausgebildet, dessen oberes Trum 32 die Kartonzuschnitte 27, 27', 27" aufnimmt und von starren Trägern 33, 33', 33" abgestützt wird, welche die Unterlage bzw. den Pressentisch bilden. Die Preßplatte 31 wird über Pressenstempel 34, 35 betätigt, welche z.B. mechanisch, pneumatisch oder hydraulisch (Druckzylinder 36) angetrieben werden und z.B. am Maschinenrahmen 11 verbunden sind. Oas Anfahren und Stoppen der Transportvorrichtungen 26 und 30 sowie das Betätigen der Presse 31, 34, 35, 36, 37 erfolgt selbsttätig in Abhängigkeit von der Betätigung eines Schalters 38 bzw. in Abhängigkeit von einem Schalter 39 an der Transportvorrichtung 26, der auf das auflaufende oder ablaufende Ende eines Kartonteiles 28 anspricht, und die Transportvorrichtung 26 und ggf. die Transportvorrichtung 30 sowie die Presae 31, 34-37 ih Bewegung versetzt. Der gesamte Bewegungsablauf ist durch eine Programmsteuerung schaltbar, so daß die Bedienungsperson lediglich die Anzahl der Kartonteile zu bestimmen hat, die zu einem Stapel zusammengefügt werden, ehe die Transportvorrichtungen in bewegung gesetzt werden.The cardboard parts 27 are guided as cardboard blanks 27a over an adhesive device 29 known per se, where they are provided with adhesive application at the adhesive points. In the case of the exemplary embodiment, the cardboard parts are fed onto the transport device 26 by hand, but can also be carried out automatically in a corresponding manner. Here, the cardboard parts are guided over the gluing device 29 in such a way that the gluing points are coated with glue and are connected to the folded part at the predetermined folding points by pressing. The cardboard parts 27, 27 ', 27 "thus provisionally bonded are stacked one above the other, exactly aligned with one another and, with the aid of the transport device 23 to 26, transferred as a common, aligned stack into the press 2 by being taken over by a transport device 30 and under of the press plate 31. The transport device 30 of the press is, for example, also designed as a belt conveyor, the upper run 32 of which receives the carton blanks 27, 27 ', 27 "and is supported by rigid supports 33, 33', 33" which support the base or The press plate 31 is actuated via press rams 34, 35, which are driven, for example, mechanically, pneumatically or hydraulically (pressure cylinder 36) and are connected, for example, to the machine frame 11. Starting and stopping the transport devices 26 and 30 and actuating the Press 31, 34, 35, 36, 37 takes place automatically depending on the actuation of a switch 38 or as a function of a switch 39 on the transport device 26, which responds to the up or down end of a cardboard part 28, and the transport device 26 and possibly the transport device 30 and the press 31, 34-37 move them. The entire movement sequence can be switched by a program control, so that the operator only has to determine the number of cardboard parts which are put together in a stack before the transport devices are set in motion.

Die Magnetanschläge sind,wie in den Fig. 3a, 3b und 3c dargestellt, so ausgebildet, daß sie einen massiven Magnetfuß 40 aufweisen, mit dem ein L-förmiger Arm 41, dessen einer Schenkel 42 mit dem Fuß 40 durch Schraubverbindung 43 befestigt ist, verbunden ist. Mit dem vertikalen Schenkel 44 des Armes 41 ist am oberen Ende bei 45 eine Metallfeder 46 befestigt, die vom der Befestigungsstelle 45 nach außen gewölbt istt und deren unteres Ende 47 freiliegt, so daß ein durch die Kartonteile27 ausgeübter Druck der Spannung der jeder 46 entgegenwirkt. Das untere Ende 47 der Feder 46 ist durch einen am Fuß 40 befestigten Anschlag 48 geführt. Die Form der Feder 46 entspricht etwa einer halben Sinuswelle, und die Kartonteile 27 liegen im unteren Teil dieser Wellenform an der jeder an, ao daß die Feder gleichzeitig als Niederhalter für die gegen die Feder gedrückten Kartonteile wirkt, indem die Wellenform der Feder verhindert, daß die Kartonteile 27 sich nach oben bewegen können. Die Magnethalterung 28 ist mit Stromanschlüssen 49, 50 versehen. Der entsprechende Stromkreis wird durch Einachalten dses Stromes geschloasen, wenn der betreffende Magnetanschlag positioniert werden soll, so daß eine einwandfreie Fixierung des Magnetanschlages erreicht wird. Durch Abschalten des Stromes läßt sich der Magnetanachlag stufenlos auf der Auflagefläche des Tisches 22 verschieben.The magnetic stops, as shown in FIGS. 3a, 3b and 3c, are designed such that they have a solid magnetic base 40 with which an L-shaped arm 41, one leg 42 of which is fastened to the base 40 by screw connection 43, connected is. With the vertical leg 44 of the arm 41, a metal spring 46 is fastened at 45 at the upper end, which is curved outwards from the fastening point 45 and whose lower end 47 is exposed, so that a pressure exerted by the cardboard parts 27 counteracts the tension of each 46. The lower end 47 of the spring 46 is guided through a stop 48 fastened to the foot 40. The shape of the spring 46 corresponds to about half a sine wave, and the cardboard parts 27 lie in the lower part of this waveform against each other, so that the spring also acts as a hold-down for the cardboard parts pressed against the spring, by the waveform of the spring preventing the cardboard parts 27 can move upwards. The magnet holder 28 is provided with power connections 49, 50. The corresponding circuit is closed by switching on this current when the magnetic stop in question is to be positioned, so that the magnetic stop is properly fixed. By switching off the current, the magnetic attachment can be shifted continuously on the support surface of the table 22.
