Description

Die Neuerung betrifft eine Arbeitsstück-Führungsvorrichtung, insbesondere Faltvorrichtung zum nähgerechten Falten eines Paspelstreifens zur Herstellung eines Tascheneingriffes ohne Patte mit Mitteln zur Festlegung der Länge der auf einer nachgeschalteten Nähmaschine zu nähenden Naht.The innovation relates to a work piece guide device, in particular a folding device for the appropriate folding of a piping strip for producing a pocket opening without flap with means for determining the length of the seam to be sewn on a downstream sewing machine.

Zur Herstellung von paspelierten Tascheneingriffen werden bekanntlich Zweinadel-Nähmaschinen eingesetzt, die mit Messern zum Aufschlitzen der Taschenöffnung sowie für das Anbringen der V-förmigen Einschnitte an den Enden derselben ausgerüstet sind. Zur nähgerechten Vorbereitung des Paspelstreifens ist einer solchen Nähmaschine eine Faltvorrichtung vorgeschaltet. Die Länge der zu nähenden Naht ist bei einfacher Fertigung durch Anzeichnen des Nahtanfanges sowie des Nahtendes auf dem Stoff bestimmt. Die Näherin kann somit den gefalteten Paspelstreifen in bekannter Weise exakt aufnähen, wobei sie zum Nahtende hin die Nähgeschwindigkeit verlangsamen muß, damit sie ihre besondere Aufmerksamkeit auf das korrekte Erreichen der Nahtendmarkierung richten kann. Es ist aber auch eine teil -automatisierte Nähanlage mit vorgeschalteter Faltvorrichtung bekannt, mittels der bei optimaler Nähgeschwindigkeit ohne menschliche Einwirkung auf den Nähvorgang Nähte an paspelierten Tascheneingriffen mit aufgesetzter Patte genäht werden können. Zu diesem Zweck wird der Durchlauf der hinteren Kante der Patte zwischen Faltvorrichtung und Nähstelle mittels einer Reflex-Lichtschranke erfaßt und sodann ein voreinstellbarer Stichzähler aktiviert, der die bis zum Nahtende hin noch zu nähende, relativ geringe Anzahl Stiche abzählt und sodann die Stillsetzung der Nähmaschine selbsttätig bewirkt. Um Paspeltaschen ohne Patte ebenfalls in einer solchen teil-automatisierten Fertigungsweise herstellen zu können, war es bisher mangels einer durch eine Reflex -Lichtschranke abtastbaren Kante im Bereich der zu nähenden Naht notwendig, den Stichzähler für das Abzählen der Stiche der gesamten Naht einzusetzen. Hierbei kann es zu nicht mehr tolerierbaren Abweichungen der tatsächlich genähten Naht von ihrer vorgegebenen Sollmaßlänge kommen, deren Ursachen z. B. unterschiedliches Transportverhalten des Nähgutes, individuell verschiedene Handführung desselben u. a. sein können. Es besteht jedoch ein Bedarf, auch Tascheneingriffe ohne Patte oder ähnliche Näharbeiten ohne Einfluß der erwähnten Störfaktoren in der geschilderten teil-automatisierten Fertigungsweise auszuführen. Diesen Bedarf deckt die Erfindung.As is known, two-needle sewing machines are used to produce piped pocket interventions, which are equipped with knives for slitting the pocket opening and for making the V-shaped incisions at the ends thereof. Such a sewing machine is preceded by a folding device for the appropriate preparation of the piping strip. The length of the seam to be sewn is determined in simple manufacture by marking the beginning and end of the seam on the fabric. The seamstress can thus sew up the folded piping strip exactly in a known manner, whereby she must slow down the sewing speed towards the end of the seam so that she can pay particular attention to the correct reaching of the seam end marking. However, a partially automated sewing system with an upstream folding device is also known, by means of which seams are sewn to piped pocket interventions with a flap at the optimum sewing speed without human intervention on the sewing process can be. For this purpose, the passage of the rear edge of the flap between the folding device and the sewing point is detected by means of a reflex light barrier and then a preset stitch counter is activated, which counts the relatively small number of stitches to be sewn to the end of the seam and then automatically stops the sewing machine causes. In order to also be able to produce piped pockets without flaps in such a partially automated production method, it was previously necessary to use the stitch counter to count the number of stitches of the entire seam due to the lack of an edge in the area of the seam to be sewn, which can be scanned by a reflex light barrier. This can lead to unacceptable deviations of the actually sewn seam from their specified nominal length, the causes of which, for. B. different transport behavior of the sewing material, individually different hand guidance of the same can be among others. However, there is a need to carry out pocket interventions without a flap or similar sewing work without the influence of the mentioned disturbing factors in the partially automated production method described. The invention meets this need.

Der Erfindung liegt die technische Aufgabe zugrunde, eine gattungsgemäße Arbeitsstück-Führungsvorrichtung derart auszubilden, daß im Zusammenwirken mit einem Stichzähler die exakte Nahtlängenbestimmung - insbesondere die genaue Länge des letzten Nahtabschnitts - auch dann möglich ist, wenn keine abtastbare Kante am Arbeitsstück, z. B. eine Patte an einem Tascheneingriff, vorhanden ist.The invention is based on the technical problem of designing a generic work piece guiding device in such a way that, in cooperation with a stitch counter, the exact seam length determination - in particular the exact length of the last seam section - is also possible when no scannable edge on the work piece, e.g. B. a flap on a pocket opening is available.

An exemplary embodiment of the innovation is described below on a folding device for the ready-to-fit preparation of a piping strip for producing a pocket opening without a flap on a downstream sewing machine with the aid of the accompanying drawings.
  • 1 is a side view of the folding device according to the invention;

Mit der Bezugszahl 1 wird eine an sich bekannte Faltvorrichtung für Paspelstreifen bezeichnet, in welcher der Paspelstreifen beim Durchlauf längs zweckmäßig geformter Bleche entsprechend, z. B. U-förmig, gefaltet wird. An die Faltvorrichtung mit entsprechend bezeichnetem Ein- und Auslaufende schließt sich eine handelsübliche Zweinadel-Nähmaschine an, die mit einem zwischen den Nadeln in vertikaler Richtung hin- und herbewegtem Messer sowie mit Messern für die V-förmigen Einschnitte an den Nahtenden ausgrüstet ist, um paspelierte Tascheneingriffe herstellen zu können. Die Faltvorrichtung ist entweder an der Maschinen-Grundplatte befestigt oder schwenkbar am Kopf der Nähmaschine angebracht. Die Tülle 2 der Faltvorrichtung wird im Bereich ihres Auslaufes von einem Halteblech 3 überragt, an welchem der Sender 4 und Empfänger 5 einer Durchlichtschranke befestigt ist. Zur Aufnahme, der zu derselben führenden Kabel 9 und 9" sind seitlich längs der Tülle 2 die Führungsrohre 8 und 8' fest angebracht. Ein vom Sender 4 ausgesandter Strahl kann durch in den Wandungen der Tülle 2 befindliche Löcher auf den Empfänger 5 treffen (Fig. 2), sofern sich kein Paspelstreifen mehr im Auslaufbereich der Tülle 2 befindet. Die dort befindliche übliche Faltzunge 6 behindert die einwandfreie Funktion der Lichtschranke 4, 5 nicht, welches mit bekannten Mitteln durch entsprechende Strahlenbündelung erreichbar ist. Während des Nähens wird der Paspelstreifen durch die Vorschuborgane der Nähmaschine durch die Tülle 2 der Faltvorrichtung gezogen und der Lichtstrahl der Lichtschranke 4, 5 wird zunächst unterbrochen. Sobald jedoch das hintere Ende des Paspelstreifens die Lichtschranke passiert hat, kann der Strahl des Senders 4 ungehindert auf den Empfänger 5 treffen. Hierdurch wird in üblicher Weise mittels eines elektrischen Signals ein nicht gezeigter, voreinstellbarer elektronischer Stichzähler bekannter Konstruktion aktiviert. Derselbe ist auf die Anzahl der Stiche eingestellt, die erfahrungsgemäß bis zum Nahtende noch genäht werden müssen. Das Nahtende kann also mit optimaler Nähgeschwindigkeit selbsttätig angesteuert werden , worauf die Nähmaschine - wiederum mit bekannten Mitteln - ohne menschlichen Eingriff abgestellt wird. Selbstver- . ständlich können auch andere Funktionen der Nähmaschine zu einem vorgegebenen Zeitpunkt inittels des Stichzählers ausgelöst werden, wenn das Nahtendbereich erreicht ist, z. B. das Nähen eines Endriegels zwecks Nahtendensicherung und/oder die Betätigung des Fadenabschneiders.The reference number 1 denotes a known folding device for piping strips, in which the piping strips are appropriately shaped as they pass along appropriately shaped sheets, e.g. B. U-shaped, is folded. The folding device with the appropriately labeled inlet and outlet ends is followed by a commercially available two-needle sewing machine, which is equipped with a knife that reciprocates between the needles in the vertical direction and with knives for the V-shaped incisions at the seam ends Pocket openings to be able to manufacture. The folding device is either attached to the machine base plate or pivotally attached to the head of the sewing machine. The grommet 2 of the folding device is surmounted in the area of its outlet by a holding plate 3, to which the transmitter 4 and receiver 5 of a transmitted light barrier are attached. For receiving the cables 9 and 9 "leading to the same, the guide tubes 8 and 8 'are fixedly attached laterally along the spout 2. A beam emitted by the transmitter 4 can strike the receiver 5 through holes in the walls of the spout 2 (FIG 2), provided there is no longer a piping strip in the outlet area of the spout 2. The conventional folding tongue 6 located there does not hinder the proper functioning of the light barrier 4, 5, which can be achieved with known means by appropriate beam bundling the feed elements of the sewing machine are pulled through the grommet 2 of the folding device and the light beam from the light barrier 4, 5 is first interrupted, however, as soon as the rear end of the piping strip has passed the light barrier, the beam from the transmitter 4 can hit the receiver 5 unhindered in the usual way by means of an electrical signal, a not shown, adjustable elect Ronic stitch counter of known design activated. The same is set to the number of stitches that experience has shown that need to be sewn to the end of the seam. The end of the seam can therefore be controlled automatically at the optimum sewing speed, whereupon the sewing machine - again using known means - is switched off without human intervention. Self-confidence. Of course, other functions of the sewing machine are triggered at a predetermined time by means of the stitch counter when the seam end area is reached, e.g. B. the sewing of an end bartack to secure the seam ends and / or the actuation of the thread cutter.

Die Tülle 2 weist in ihrem mittleren Bereich einen Ausbruch auf, durch welchen (Fig. 4) eine Anlegeskala 7 sichtbar wird, die mit einer Gradeinteilung in Millimetern versehen ist. Die Näherin schiebt den Paspelstreifen soweit in die Faltvorrichtung ein, bis die hintere Kante desselben an einer jeweils vorgegebenen Millimeterzahl anliegt. Hierdurch wird die Länge des zu nähenden Tascheneingriffes genau vorbestimmt. Statt einer Skala mit Millimetereinteilung können Markierungen beliebiger Ausführung vorgesehen sein, damit die Näherin leicht reproduzierbare Werte als Arbeitsgrundlage hat.The grommet 2 has a cutout in its central area, through which (FIG. 4) a contact scale 7 is visible, which is provided with a graduation in millimeters. The seamstress pushes the piping strip into the folding device until the rear edge of it lies against a predetermined number of millimeters. As a result, the length of the pocket opening to be sewn is precisely predetermined. Instead of a scale with millimeter gradations, markings of any design can be provided so that the seamstress has easily reproducible values as a basis for work.

Es können durch die Neuerung bei vertretbarem Aufwand Tascheneingriffe ohne Patte sehr präzise hergestellt werden, da auftretende Störeinflüsse sich bei der neuerungsgemäßen Faltvorrichtung mit Mitteln zur Nahtlängenbestimmung nur geringfügig auswirken können und sich innerhalb vertretbarer Toleranzgrenzen halten. Der Grund hierfür liegt in der Tatsache, daß die vom Stichzähler auszuzählende Anzahl der Stiche relativ gering ist. Sie entspricht lediglich der kurzen Nähstrecke zwischen der Lichtschranke am Auslauf der Faltvorrichtung und den Nadeln der Nähmaschine minus dem Maß, um welches der Paspelstreifen über das Nahtende hinausragt. Auf einer solchen kurzen Nähstrecke können sich Störeinflüsse, wie z. B. unterschiedliche Transportgeschwindigkeit des Nähgutes usw. , nicht mehr schädlich auswirken. ;With the innovation, pocket interventions without flap can be produced very precisely with reasonable effort, since the disturbing influences that occur with the folding device according to the innovation with means for determining the seam length can only have a minor effect and are kept within acceptable tolerance limits. The reason for this lies in the fact that the number of stitches to be counted by the stitch counter is relatively small. It only corresponds to the short sewing distance between the light barrier at the outlet of the folding device and the needles of the sewing machine minus the amount by which the piping strips protrude beyond the seam end. On such a short sewing distance, interference such as B. different transport speed of the sewing material, etc., no longer have a detrimental effect. ;

Die Neuerung beschränkt sich nicht auf das geschilderte Ausführungsbeispiel einer Faltvorrichtung. Es lassen sich vielmehr auch andere Arbeitsstück-Führungsvorrichtungen neuerungsgemäß ausrüsten, z. B. Reißverschluß-Zuführungen oder auch sonstige, einer Nähmaschine vorgeordnete Vorrichtungen zum Führen und/oder Formen von vorzugsweise streifenförmigem Nähgut.The innovation is not limited to the described embodiment of a folding device. Rather, it is also possible to equip other work piece guiding devices according to the innovation, for. B. zipper feeds or other devices upstream of a sewing machine for guiding and / or shaping preferably strip-shaped material.
