Description
Maschine zum Zunähen gefüllter Säcke mit einem Kreismesser Die Erfindung bezieht sich auf eine Nähmaschine zum Zunähen gefüllter Säcke, welche mit einer Vorrichtung zum Durchschneiden der vom einen Sack zum vorangehenden Sack laufenden Fadenkette, mit welcher die Säcke verschlossen werden, versehen ist. Im besonderen bezieht sich die Erfindung auf eine Nähmaschine dieser Art, wobei die Schneidvorrichtung aus einem Kreismesser besteht, welches ortsfest hinter der Tischplatte gelagert ist.Machine for sewing up filled sacks with a circular knife The invention refers to a sewing machine for sewing up filled sacks, which is equipped with a Device for cutting through the sack running from one sack to the preceding one Thread chain with which the bags are closed is provided. In particular The invention relates to a sewing machine of this type, wherein the cutting device consists of a circular knife, which is stored in a fixed position behind the table top is.
Das Wesen der Erfindung besteht nun darin, daß das Messer in einer Vertiefung der Tischplatte liegt, wodurch Verletzungen beim Abschneiden ausgeschaltet sind. Überdies hat die Anordnung des Messers hinter der Tischplatte den Vorzug, daß es dort die Sicht nicht stört, wie wenn. das Messer vor der Tischplatte angeordnet ist, wo es zudem auch behindert.The essence of the invention is that the knife in a Deepening of the table top lies, which eliminates injuries when cutting off are. In addition, the arrangement of the knife behind the table top has the advantage of that it does not disturb the view there, as if. the knife placed in front of the table top is where it also hinders.
Ein weiterer Vorteil der Anordnung des Messers in der Vertiefung besteht darin, daß das Durchschneiden der Kette außerordentlich erleichtert ist und sogar selbsttätig vorgenommen werden kann. Es genügt, die Kette einen Augenblick gegen das Messer zu drücken oder, wenn das Abschneiden selbsttätig vorgenommen werden soll, eine Anordnung zu treffen, durch welche der Sack bei seinem Abtransport etwas kippt und dadurch seine Kette gegen das Messer drückt.Another advantage of arranging the knife in the recess is there in that the cutting of the chain is and even is greatly facilitated can be done automatically. Suffice it to stop the chain for a moment to press the knife or if the cutting is done automatically is supposed to make an arrangement by which the sack something when it is transported away tilts and thereby presses his chain against the knife.
Der Gegenstand vorliegender Erfindung ist auf der Zeichnung in beispielsweisen Ausführungsformen näher erläutert.The subject matter of the present invention is shown in the drawing by way of example Embodiments explained in more detail.
Abb. i zeigt die Anwendung der Schneid-e, in Vorderansicht.Fig. I shows the use of the cutting edge , in a front view.
Abb. :2 und 3 sind Seitenansicht und Draufsicht, zum Teil geschnitten, bei Antrieb durch die Nähmaschine.Fig.: 2 and 3 are side and plan views, partly in section, when driven by the sewing machine.
Abb. 4 und 5 sind gleiche Ansichten bei elektromotorischem Antrieb.Fig. 4 and 5 are the same views with an electric motor drive.
Die zuzunähenden Säcke a werden der Nähtnaschine b auf einer Transportvorrichtung c stehend einzeln nacheinander zugeführt und durch die mit waagerechter Nadel arbeitende Nähmaschine b zugenäht. Zum Durchschneiden der Kette d, mit welcher die Säcke a zu- genäht werden, dient ein rotierendes Kreismesser e, gegen welches die Kette d gedrückt und dadurch durchschnitten wird. Das Messer e liegt in einer Vertiefung g der Tischplatte f, in welche die Schneide ragt und in welche die Kette d eingedrückt wird. Diese Vertiefung g liegt waagerecht und ist zweckmäßigerweise rinnenförmig ausgestaltet. Sie steigt gegen die stichbildenden Elemente an und geht hier in die Fläche der Tischplatte f über, während sie auf der Abtransportseite der Säcke a für den Durchgang der Kette d offen steht.The sacks a to be sewn are fed individually to the sewing machine b standing on a transport device c and sewn closed by the sewing machine b operating with a horizontal needle. A rotating circular knife e, against which the chain d is pressed and thereby cut, is used to cut through the chain d with which the bags a are sewn shut. The knife e lies in a recess g of the table top f, into which the cutting edge protrudes and into which the chain d is pressed. This depression g lies horizontally and is expediently designed in the shape of a channel. It rises towards the stitch-forming elements and merges here into the surface of the table top f, while it is open on the transport side of the sacks a for the passage of the chain d.
Bei der in Abb. :2 und 3 dargestellten Ausführung wird das Kreismesser e von der Nähmaschine selbst angetrieben. Es sitzt auf einer waagerechten Achse la, welche in den Lagerungen i eines an der Nähmaschine b angeschraubten Bockes k dreht und senkrecht zur Hauptantriebsachse l der N ähmaschine b verläuft. Deren Drehbewegungen werden mittels Verzahnungen, wie z. B. Schrauben-oder Schneckenrädern na, auf die Achse lt und damit auf das Kreismesser e übertragen.In the version shown in Fig. 2 and 3, the circular knife e is driven by the sewing machine itself. It sits on a horizontal axis la, which in the bearings of a i b at the sewing machine bolted bracket k rotates and perpendicular to the main drive axis l of N ähmaschine b runs. Their rotary movements are made by means of gears, such as. B. screw or worm wheels na, on the axis lt and thus transferred to the circular knife e.
Abb. q. und 5 zeigen einen Antrieb des Kreismessers e durch einen Elektromotor ia.Fig.q. and 5 show a drive of the circular knife e by an electric motor ia.
