Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von Versandbeuteln einschließlich von Briefumschlägen aus bahnförmigem Werkstoff, der mit Hilfe von mehreren Verfahrensschritten und entsprechend in mehreren Arbeitsstationen in vielfältiger Weise bearbeitet wird (siehe zum Beispiel US-A-3 400 641). Der bahnförmige Werkstoff wird dazu an seinen Rändern beschnitten und durchtrennt, mit Klebstoff versehen, gefaltet und verklebt. In besonderen Fällen wird auch ein zweites, flächiges Teil wie z. B. ein Fensterzuschnitt, ein Aufkleber, ein Klebstoff - Abdeckstreifen oder auch ein sonstiges, zustätzliches, den Versandbeutel bzw. den Briefumschlagrohling bildendes Teil mit Hilfe von Klebstoff unmittelbar noch an dem bahnförmigen Werkstoff oder an einem Zuschnitt bzw. Rohling befestigt. Der damit verbundene technische Aufwand ist groß und stellt vor allem ein Problem dar, wenn es darum geht, die Stückzahl der herzustellenden Versandbeutel bzw. Briefumschläge pro Zeiteinheit deutlich zu erhöhen.The invention relates to a method and an apparatus for manufacturing of mailers, including envelopes of web-like Material, with the help of several process steps and correspondingly in multiple workstations in a variety of ways is processed (see, for example, US-A-3 400 641). The web-shaped material is at its edges cut and cut, with adhesive, folded and bonded. In special cases, a second, flat part like z. B. a window blank, a sticker, an adhesive - cover strip or another, additional, the shipping bag or the Envelope blank forming part with the help of adhesive directly still on the sheet-like material or on a blank or Rough attached. The associated technical effort is great and above all, it is a problem when it comes to the number of pieces the shipping bag or envelopes to be produced per To significantly increase the time unit.
Der Erfindung liegt daher die Aufgabe zugrunde, Verfahrensschritte und die zugehörige Vorrichtung anzugeben, mit deren Hilfe es möglich ist, die Stückzahl pro Zeiteinheit bei der Herstellung von Versandbeuteln einschließlich von Briefumschlägen zu erhöhen, die nicht nur aus einem Teil, sondern aus mindestens zwei zunächst getrennten Teilen bestehen.The invention is therefore based on the object process steps and to provide the associated device with the help of which it is possible is the number of pieces per unit of time in the production of shipping bags including from envelopes that not only increase a part, but from at least two initially separate parts consist.
Zur Lösung der besagten Aufgabe sieht die Erfindung mit den Merkmalen von Anspruch 1 vor, daß sich mindestens eines der beiden Teile und/oder sein Träger im Bereich der Verbindungsstelle wellenförmig bewegen. Die eigentliche Kontakt- und Verbindungsstelle ist nur minimal größer als eine linienförmige Kontaktfläche. Ihre Krümmung und Lage ist durch die Krümmung der als Auftragswalze dienenden Saugwalze vorgegeben. Unmittelbar neben der eigentlichen Kontaktstelle ist die Krümmung von mindestens einem der beiden Teile und/oder seines Trägers entgegen der Krümmung der Auftragswalze gerichtet und geht dann sofort in eine vorzugsweise gemeinsame Ebene über. Die jeweiligen Bogenstücke sind extrem kurz.To solve the said problem, the invention provides the features Of claim 1, that at least one of the two parts and / or its support in the region of the joint wavy move. The actual contact and connection point is minimal larger than a linear contact surface. Your curvature and Location is due to the curvature of the suction roller serving as the application roller specified. Immediately next to the actual contact point is the curvature of at least one of the two parts and / or its Straightened against the curvature of the applicator roll and goes then immediately into a preferably common level. The respective ones Arched pieces are extremely short.
Die Führung und Handhabung beider Teile beim Aufeinanderlegen und Verkleben ist in der besagten Weise einfacher als bisher, insbesondere weil nahezu keine durch die Krümmung bedingten Gurtspannungen auftreten und auch weil in der Regel nur eines der beiden miteinander zu verbindenden Teile entsprechend der Krümmung der Auftragswalze abgebogen werden muß. Mindestens eines der beiden Teilen läuft daher nahezu geradlinig durch die Kontakt- und Verbindungsstelle und wird dennoch minimal wellenförmig geführt. Die Folge hiervon ist, daß sich größere Stückzahlen als bisher pro Zeiteinheit erzielen lassen.The leadership and handling of both parts when stacking and Gluing is easier in the said way than before, in particular because almost no due to the curvature belt tension occur and also because usually only one of the two together parts to be joined according to the curvature of the applicator roll must be bent. At least one of the two parts is running almost straight through the contact and junction and is nevertheless guided in a minimal wavy manner. The consequence of this is that Larger quantities than previously achieved per unit time.
Zur Durchführung des erfindungsgemäßen Verfahrens ist ferner vorgesehen, daß sich mindestens eines der beiden Teile und/oder sein Träger an der Verbindungsstelle zunächst konvex in eine Mulde und sodann konkav durch die Mulde und schließlich wieder konvex aus der Mulde bewegen. Die jeweiligen Bogenstücke sind extrem kurz und verursachen daher auch keine ausgeprägte, sondern nur eine minimale Krümmung. Um dies zu erreichen, ist die Mulde gemäß der Erfindung nur flach und kann eine größte Tiefe von zum Beispiel 1,5 mm bis 2 mm besitzen.For carrying out the method according to the invention it is further provided that at least one of the two parts and / or its carrier at the junction first convex in a trough and then concave through the hollow and finally convex out of the Move trough. The respective bow pieces are extremely short and cause therefore no pronounced, but only a minimal Curvature. To achieve this, the trough is according to the invention only shallow and can have a maximum depth of for example 1.5 mm to 2 mm own.

Eine Vorrichtung 1 zum Herstellen von Versandbeuteln einschließlich
von Briefumschlägen aus bahnförmigem Werkstoff 2 bzw. 3 umfaßt
mehrere Baugruppen 4, in denen der Werkstoff 2, 3 in vielfältiger Weise
bearbeitet wird. Dazu wird er zugeschnitten, mit Vorbrüchen versehen,
gefaltet, mit Leim versehen und zum fertigen Produkt zusammengelegt.
Bei der Herstellung verschiedener Versandbeutel und auch verschiedener
Briefumschläge ist es erforderlich, an mindestens einer
Verbindungsstelle 5 zwei getrennt vorbereitete Teile 6, 7 aneinander zu
befestigen bzw. mit Hilfe von Klebstoff miteinander zu verbinden. Die
beiden Teile 6, 7 können z. B. ein Fensterzuschnitt einerseits und ein
Briefumschlagzuschnitt andererseits und/oder andersartige, bereits
vereinzelte Teile oder noch bahnförmiges, noch nicht in Einzelteile geschnittenes
Material sein. Wesentlich ist, dass an der Verbindungsstelle
5 der Vorrichtung 1 ein bereits mit Klebstoff versehenes Teil und ein
weiteres Teil zusammengeführt und sodann im Kontaktbereich bei
ausreichendem Anpressdruck miteinander verbunden werden.An apparatus 1 for producing mailer bags including
envelopes of

eine Saugeinrichtung 8. Gemäß Ausführungsbeispiel ist die Saugeinrichtung
8 eine als Auftragswalze dienende Saugwalze 8'.At the
Als Träger für das andere Teil 7 dient im Bereich der Verbindungsstelle
5 eine mindestens einen Gurt aufweisende Transporteinrichtung 9. Sie
transportiert das Teil 7 zur Verbindungsstelle 5, durch diese hindurch
und sodann von dieser weg. Gemäß Ausführungsbeispiel handelt es
sich bei der Transporteinrichtung 9 um eine mit Unterdruck arbeitende,
mindestens einen Sauggurt aufweisende Transporteinrichtung.As a support for the
Die Sauggurt-Transporteinrichtung 9 umfaßt einen Saugkasten 10 und
weist ferner mit Abstand voneinander angeordnete Transportgurte 11
sowie Umlenkrollen 12 und eine Einrichtung 13 zum Spannen der
Transportgurte 11 auf.The suction
Die Sauggurt-Transporteinrichtung 9 dient jedoch nicht nur als Träger
für das eine Teil 7, sondern auch als Gegenwerkzeug für die Saugwalze
8'. Die Saugwalze 8' transportiert ihrerseits das andere Teil 6 an die
Verbindungsstelle 5 und hält und führt es dort. Sie hat zugleich die
Funktion eines Aufklebezylinders.The suction
Der Saugkasten 10 weist in seiner den Transportgurten 11 zugewandten
Oberseite 14 parallel zueinander angeordnete, grundsätzlich bekannte
Saugöffnungen bzw. Schlitze 15' und 15'' auf (Figur 4). Ferner
befindet sich in der Oberseite 14 bzw. in der diese Oberseite bildenden
Deckplatte 15 eine Vertiefung bzw. Ausnehmung oder Mulde
16. Im Ruhezustand bzw. ohne die Teile 6 und 7 liegen die Transportgurte
11 unmittelbar auf der Deckplatte 15. Sie sind mit einer konstanten
Kraft vorgespannt und erstrecken sich geradlinig über die
Deckplatte 15 und berühren den Umfang 17 der Saugwalze 8' tangential.
Die Transportgurte 11 tauchen in diesem Betriebszustand (Ruhezustand
ohne Teile 6 und 7) nicht in die Mulde 16 ein, so daß sich ihre
Zähne 18 in einem deutlichen Abstand über dem Muldengrund 19 befinden
(Fig. 2). Wenn jedoch gemäß Figur 3 die Saugwalze 8' ein Teil
6 und gleichermaßen die Transportgurte 11 ein Teil 7 in den Muldenbereich
bzw. durch die Verbindungsstelle 5 transportieren, so werden
die Transportgurte 11 entsprechend der Materialstärke der beiden Teile
6 und 7 in die Mulde 16 gedrückt (Figur 3). Auch in dieser Situation
berühren die Zähne 18 der Transportgurte 11 nicht den Muldengrund
19.The
Beim Verbinden treffen die längs der Kontur bzw. längs des Umfanges
17 der Saugwalze 8' transportierten Teile 6 spitzwinklig auf die Teile
7, die sich ihrerseits wegen ihrer Materialstärke ebenfalls spitzwinklig
zum Umfang 17 der Saugwalze 8' bewegen. Die Teile 7 treffen nicht
tangential auf die Teile 6 am Anfang der Verbindungsstelle 5. Sie werden
dadurch zunächst konvex in Richtung Mulde abgelenkt und bewegen
sich sodann konkav zur Mulde 16. Während des unmittelbaren
Kontaktes der beiden Teile 6, 7 bewegen sie sich kurzfristig längs einer
bogenförmigen Strecke entsprechend der Kontur der Saugwalze 8'.
Grundsätzlich Gleiches gilt für die Bewegung der Transportgurte 11.When joining the meet along the contour or along the
Während des Zusammenführens und Verbindens der beiden Teile 6, 7
dienen die an der Kontaktstelle nicht unmittelbar abgestützten Transportgurte
11 zugleich als Anpreßwerkzeug bzw. als Gegenwerkzeug für
die Saugwalze 8'. Längs eines kurzen Bogenstückes sowie kurzzeitig
umschlingen die Transportgurte 11 zusammen mit den beiden Teilen 6
und 7 die Saugwalze 8'. Dabei bewegen sich die Transportgurte 11
zunächst konvex zur Mulde 16 und sodann konkav längs der Mulde 16
und schließlich wieder konvex zur Mulde 16. Die Transportgurte 11
tauchen etwas bogenförmig konkav in die Mulde 16 ein. Aufgrund der
Gurtspannung werden die Teile 6 und 7 zugleich mit konstanter Kraft
aneinander gedrückt.During the merging and joining of the two

der Oberseite 14 des die Transportgurte 11 tragenden Saugkastens
11 beträgt etwa 1,5 bis 2 Millimeter. Wesentlich ist, dass die
Transportgurte 11 auch im Betriebszustand gemäß Figur 3 den Muldengrund
19 nicht berühren.The contour of the
