Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Schliefsen von Briefumschlägen und bezweckt die Herstellung" einer Maschine, die rasch und zuverlässig arbeitet. The present invention relates to a device for closing envelopes and aims to produce "a machine that works quickly and reliably.

Die Zeichnungen veranschaulichen die Erfindung, und zwar zeigt:The drawings illustrate the invention and show:

Fig. 2 eine Draufsicht,Fig. 2 is a plan view,

Fig. 3 eine Schnittansicht nach der Linie 3-3 der Fig. 2 (die Vorrichtung ist hier in der Stellung dargestellt, in welcher das Anfeuchten erfolgt),Fig. 3 is a sectional view along the line 3-3 of Fig. 2 (the device is here in the position in which the moistening takes place),

Fig. 4 einen Schnitt nach der Linie 4-4 der Fig. 2 (in der Stellung", in welcher die Schliefsrollen in Thätigkeit sind).Fig. 4 is a section along the line 4-4 of FIG. 2 (in the position "in which the castors are in action).

Fig. S ist eine Einzelansicht der Druckrollen zum Anfeuchten.Fig. 5 is a detailed view of the dampening pressure rollers.

ι ist eine Unterlagsplatte, 2 ein fester Tisch zur Aufnahme des Umschlages. Auf diesem befindet sich eine Führung oder Einstellvorrichtung 3.ι is a base plate, 2 is a fixed table for receiving the envelope. On this one there is a guide or adjustment device 3.

In der Verlängerung des Tisches 2 befindet sich ein schwingend angeordneter Tisch 2". Dieser wird von Armen 4, die bei 5 drehbar aiigelenkt sind, getragen und von einer Feder 6 in richtiger Stellung gehalten (Fig. 1), An den Armen 4 ist gleichzeitig die Vorrichtung zum Anfeuchten angebracht. Sie besteht aus einer mit Filz oder ähnlichem wasseraufsaugenden Stoff 8 belegten Platte 7. Der Filzstreifen taucht in ein Wassergefäfs 9 ein.In the extension of the table 2 there is a swinging table 2 ″. This is carried by arms 4, which are pivoted at 5, and by a spring 6 held in the correct position (Fig. 1), On the arms 4 is also the device attached for moistening. It consists of a water-absorbent one with felt or similar Fabric 8 occupied plate 7. The felt strip is immersed in a water vessel 9.

Zu beiden Seiten der Vorrichtung sind Stützen -ίο angebracht. An jeder derselben sind durch einen Querstab 11" verbundene Arme 11 drehbar angelenkt.Supports -ίο are attached to both sides of the device. At each of them are connected by a cross bar 11 " Arms 11 are rotatably articulated.

An den Armen 11 sind die Walzen zum Schliefsen des Umschlages gelagert. Diese bestehen aus einer Triebwalze 13 und einer durch Reibung angetriebenen Walze 14.The rollers for closing the envelope are mounted on the arms 11. These consist of a drive roller 13 and a roller 14 driven by friction.

Die Walze 13 erhält ihre Drehung in folgender Weise:The roller 13 gets its rotation in the following way:

In ein Sperrrad 18 auf der Walzenachse greift ein Sperrhaken 16, der von einer Scheibe 17 getragen wird, ein. Die Scheibe 17 erhält ihre Drehung von einem in ein Rad 19 eingreifenden Rade 18. Das Rad 19 greift bei der Bewegung der Arme 11 in ein Zahnsegment 20, das mit den Seitenstücken 10 fest verbunden ist, ein.In a ratchet wheel 18 on the roller axis a ratchet 16 carried by a disc 17 engages. The disk 17 receives its rotation from a wheel 18 engaging in a wheel 19. The wheel 19 engages during the movement of the arms 11 in a toothed segment 20, which is fixed to the side pieces 10 connected, a.

Ein Handgriff oder dergl. 21 dient zur Drehung der Arme 11 um ihre Drehzapfen 11".A handle or the like. 21 is used for Rotation of the arms 11 about their pivot pins 11 ".

Ein Anschlag 22 kommt mit dem schwingenden Tisch 3 in Berührung und dreht diesen dadurch bei Seite, so clafs die Schliefswalzen den Umschlag" erfassen können.A stop 22 comes into contact with the vibrating table 3 and rotates it thereby aside, so the sleeping rollers the envelope "can capture.

Die Arme 11 werden durch Federn 23 in ihre ursprüngliche Lage, zurückgezogen. Vom Fufsstück ι gehen Pfosten 24 aus, an welchen ein Rahmen 25 mit Querstäben 26 drehbar angelenkt ist. In diesem Rahmen sind Stifte 27 verschiebbar angeordnet. Diese werden durch Federn .28 nach vorn geprefst und sind an ihrem vorderen Ende mit Druckrollen 29 versehen. Diese sind dazu bestimmt, die Klappe des Umschlages fest gegen die Anfeuchtfläche zu pressen.The arms 11 are retracted into their original position by springs 23. From the Fufsstück ι go from posts 24 to which a frame 25 with cross bars 26 is rotatably hinged is. Pins 27 are slidably arranged in this frame. These are through Springs .28 pressed forward and are provided with pressure rollers 29 at their front end. These are designed to hold the flap of the envelope firmly against the moistening surface to press.

Claims

The front end of the frame 25 is suspended from levers 34 which at one end have the frame 25 and on the other with the arms 11 are rotatably connected.

The tension of the springs 28 can be regulated by adjusting screws 30 (FIG. 5). These are threaded at their lower end and go through the Ouerstab 26, which they adjust when they are tightened.

The screw has a head 32.

Instead of two pins 27 and a single pressure roller, a larger one can also be used A number of such pins may be present (FIG. 5), two of which are connected by a roller 29 are. All of the rollers then act like one.

The advantage of this arrangement is as follows. ■ ■. . '

If a large number of such machines are to be manufactured, it may that the moistening surface and the axis of the roller 29 do not become parallel.

However, this would impair the reliable operation of the device.

This inconvenience is avoided by arranging several rollers.

The operation of the device is as follows.

The setting device 3 is set so that the envelope α, placed on the table, hangs down with its flap b so that the latter lies on the moistening surface (FIG. 1). Then the frame containing the sleeping rollers is rotated against the table, the rollers 29 coming into contact with the flap b (Fig. 3).

If the frame is rotated further, the flap is first firmly attached to the damp surface praised, whereupon under the action of the stop 22 the swinging part of the table is turned downwards. The folded edge of the envelope is then removed from the Prefswalzen grabbed and the frame turned back again, taking the envelope " who holds him during the backward movement, so that during this time the gluing takes place.

When the frame moves backwards, the locking hook 16 does not cause any movement the idler rollers while engaging the ratchet wheel as it moves forward; so that the rollers are set in rotation, thereby the flap firmly on the envelope press on and finally convey the latter onto a collecting table 33.

Godfather nt-A ν Proverbs:

ι. A device for closing Envelopes, in which the envelope is placed on a two-part table, moistened and then by slack rollers is detected, characterized in that the swing-mounted arms of the device carrying the sleeping rollers can be approached and removed from the carrying table, with the arms, when they are moved to the table for the purpose of gripping the envelope after moistening, the movable ones, the moistening surface push the supporting part of it out of the way.

2. An embodiment of the device according to claim 1, characterized by a shoulder (22) on the arms (11) carrying the sleeping rollers, which for this purpose serves to fold down the swinging part (2 ") of the support table when the arms are moved against it.

3. An embodiment of the device according to claim 1, characterized in that that the foldable part (2 ") of the table is pivoted on an arm (4) and is held in the normal position by a spring (6).

4. An embodiment of the device according to claim 1, characterized in that that those carrying the idle rollers are connected by a cross rod (12) Arms (11) pivoted to supports (10) and are held in their normal position by a spring (23).
