PATENT LETTERING

CLASS 79: Tobacco.

Patented in the German Empire on July 25, 1886.

The present invention comprises on the one hand the various mechanisms which are used for continuous production of non-glued paper tubes for filling them with tobacco and serve to store the finished gigarettes and, on the other hand, the compilation of these different mechanisms to one in their mode of action and their entirety entirely new machine, which one both by the uniformity of the produced Cigarettes, as well as the processing of raw materials, which is excellent due to the very large production enables.

According to my invention, the paper wound on a roll is transformed into an endless tube which is closed by inner folding of the longitudinal edges of the endless paper; thereon a pair of scissors cuts the sleeve thus formed in some parts of mathematically certain length which fall on a pair of pins studded rods to one another, which perform a reciprocating rotational movement by 90 ⁰ and due to their inclined arrangement of the transport of the sleeves up to arrange for the stuffing or filling apparatus. There the sleeves are pushed onto a funnel-like attachment tube and clamped onto the same. The tobacco roll intended for filling comes out of the neck tube and is pushed into the sleeve by a pusher operating in accordance with the tobacco distribution and pressing device. Finally, the cigarettes obtained in this way are packed in a box of a customary shape.

On the accompanying drawings, Figs. 1 and 2 illustrate the Aufrifs and the basic riff of my new cigarette machine. 3 and 4 are cross-sections according to the Lines 1-2 and 3-4 of FIG. 1.

The machine is set up as follows:

A base frame, which is attached to the floor or just rests on the same, carries the cast iron table a on which the tools and mechanisms forming the cigarette are assembled. First a shaft b, which is arranged on the upper side of the table in two bearings b ^l b ² attached to the latter. This shaft carries the cam c moving the stuffing mechanism, the cam d actuating the tobacco preform, the thumb e for moving the clamping pliers, the cam / for transporting the sleeves, the thumb g for feeding the paper, which with the cam h for moving the guide rod which pushes the sleeve onto the stuffing funnel and forms a body with the cam disk i for moving the scissors, and finally the cam disk j for the plunger.

Below the table a shaft k rotating in the bearings of the blocks A: ¹ k ' ² carries the thumb / the packaging device, the thumb m of the Prefs- and distribution slide and the thumb m ^{l of} the tobacco feeder, then a gear, κ, which the Chains of the tobacco distributor convey movement.

The shafts b and k get their movement from the intermediate shaft 0, which with pulleys 0 ¹ O ² , a flywheel o ³ and

a gear ο ^{4 is} provided, which the latter with the same size gears b ³ and k ^{s of} the main shafts b k. is engaged.

At the end of the machine opposite the transmission, I arrange the entire device used to manufacture the non-glued sleeve on a plate P ⁰ screwed to the table α.

Manufacture of the pods.

The paper p, which is wound onto the drum p ^l , which is movably mounted in a forked stand p ² , runs first over a roller p ³ , then over a second roller p ⁴ , which sits on a tension spring p ^h , and then over other intermediate rollers p ^a p ⁷ p ⁸ to finally go over a last roller p ⁹ , which is located immediately in front of the device for forming the sleeve.

The drum p ¹ , rotatable on its axis, is subjected to the action of a brake, a kind of locking spring, p ^x , the free end of which grinds on a metal ring attached to the drum; the greater the pressure exerted by the screw p? exerts on the spring p ^x.

From the last guide roller ρ ⁹ the paper goes through a drawing iron q , FIGS. I, 2, 9 and io (FIG. Io is a section according to 5-6 of FIG. 9); in which the end of a round dome r, Fig. 5, 6, 7 and 8, is suspended. The paper, which has a tubular cross-section, places its longitudinal edges against the fastening pin q ^{l of} the dome r. : A screw q ^x sitting in the head of the drawing iron q presses on the end of the dome r , which is only suspended in the drawing iron, otherwise freely floating, and serves to maintain the position and to precisely adjust the latter.

- Behind the drawing iron, the paper encircles the thorn r, which preserves the cylindrical Secures the shape of the paper and the formed sleeve to its complete completion serves as a guide.

The mandrel r is provided on its upper side with a longitudinal groove r ¹ , in which the edges of the paper with the aid of a prefinger s, Fig. 8, section according to 7-8 of Fig. 1, whose acting surface has a special shape to be pushed in. The prefinger is suspended from the end of a spring s ¹ attached to the drawing die q , the pressure of which (and consequently the pressure of the prefinger on the paper) can be changed as required ^{by a screw s 2.}

At the end of the groove r ^{1 of} the dome, the paper surrounds the folding device t, which is embedded in the mandrel.

This device t, FIGS. 5, 6 and 7, consists of a tough, fine-grained piece of metal which is conically drilled through and has a sufficiently large inlet opening and a very small outlet opening; ^{a slit i 1} , which is enlarged at the front and gradually narrows in it, makes the conical hole of the piece t accessible on the upper surface of the latter. The turned down edges of the paper follow the slot t ^x and are curled or folded into one another as they move forward by the decreasing cross-sections of the former t.

Immediately in front of the former t , the closed sleeve goes through a second drawing iron u , which is concentric to the mandrel and which prepares the sleeping fold. After leaving the former, the sleeve gets between the knurled wheel r ³ mounted in the mandrel r and the transport roller ν, which is ^{arranged just above the wheel r 3} , Fig. I, 2 and 11. The wheel r ³ and the roller ν exert so great a pressure on the paper, which they jointly pull forward, that the longitudinal closure of the sleeve is completed, that is, that the different paper thicknesses and -Layers which the former t has joined together - are firmly united with one another ';

The sleeve formed receives the required forward movement with the aid of a toothed rack x, FIGS. 2 and 3, which is set in an upward and downward movement by the thumb g. The movement of the rack χ is converted by a locking device into an intermittent rotation of the roller v, F ¹ Ig: 5, which is constantly taking place in the same direction. The magnitude of the movement of the roller ν can be calculated in such a way that it is sufficient to wrap the paper at once by an amount equal to the length of the cigarette to be formed. or so that it corresponds to the advancement of the paper by half a length of the finished cigarette, as takes place in the machine shown. In this case the advancement of an entire tube is accomplished in two steps. ^;

As soon as the ^{core leaves the rollers r 3} and ν , it is completely closed by the edges of the paper which are united with one another inside the core. In this way it can be produced in any length and even in a length which is equal to the total length of the paper wound on the drum.

In order to cut the endless sleeve into individual sleeves of the length which is to receive the finished cigarette, I arrange in the vicinity of the rollers r ³ ν immediately behind the tongue-shaped rounded end of the Dornest two to z ^'3 rotatable Scheer leaves i ^1/2 an, Fig. 4, the rear ends of which are connected to one another by a spring i ^{4, which}

constantly seeks to close the shear leaves. The Oeffhen the latter is done by a · between her thighs i ^l i ² arranged thumb 'i ⁵ which is i8o ° back and forth rotates. This movement of the thumb i ⁵ takes place after each advance of the paper by a sleeve length with the aid of the cam disk i, the lever z ⁶ , the link i ⁷ and the lever i ⁸ , FIGS. 3 and 4. In the front, the legs Pi ^{2 are} with thin shear blades i ^x i ^x provided, which can be easily and quickly attached and removed again to enable them to be sanded down or replaced; ^{two teeth i 9} in constant contact with one another on the legs i ^x i ² ensure the rectilinear movement of the scissor blades, although a certain amount of play remains between them, as is the case with the scissors of ordinary scissors.

The transport roller ν rests with the ends of the axle on which it is attached in bearings v ¹ v ² , the covers of which can be opened and are kept in the closed position ^{by springs v 3.} This device enables easy removal of the roll in the event that an inspection of the 'fold former is necessary.

Before we put the paper tubes, which the scissors. V i has cut ^2, followed by its further way is to be mentioned "That the paper between the guide rollers p ⁷ p ^8, Fig. L ·, a trade mark or a different imprint of a printing stamp j received ^1, which in 'a carrier provided with the abutment j ² for the punch _ / ³ is movable up and down, is mounted and is moved by the cam plate j of the shaft " b . Before the printed paper arrives at the drawing iron q on its way over the rollers p ^s and p ⁹ , the. printed area completely dried. '

: Finally it should be noted that by tightening the screw q ^x , Fig. 2, the free end of the dome r can be raised more or less, that is, the wheel r ³ can more or less approach the roller ν. This is a simple and safe means of regulating the pressure which is necessary to complete the longitudinal closure of the paper tube.

Transport of the pods.
The sleeves are located in the moment when they are cut by the scissors i ¹ i ^2, a few millimeters are highly equipped with two inclined rods Z ^1/2 which with two right angles to each other arranged rows of equidistant from each other protruding pins , the pins in one row being staggered in a regular manner to the pins in the second row.

The bars / ^1/2, Fig. 1, 2 and 4, which by means of two equally grofser toothed Sectoren / ^3/4 with two only toothed partly wheels / ^5/6 are engaged, received by the curve disc / for each revolution of shaft .b a reciprocating rotational movement around go degrees, such, that the cut sleeve by falling on the ladders / ^1/2, are retained by the first pins of the first row, the at the reverse movement of the conductors up to fall second pins of the second row and so on with every movement of the rods / ^1/2, which is also the direction of movement to a rung go down lower. Finally, each of these tubes gradually arrives opposite a funnel w , FIGS. 1 and 13, which is located in front of the extension tube w ^x which protrudes laterally from the cavity of the tobacco press.

In this position, with the curve disc h-related lever / 1 ^1, 2 and 3 gives., The guide bar h ² a forward movement and thereby stöfst the sleeve into the hopper w and thence w on the neck tube ^1.

Clamping the sleeves on the attachment tube w \

A lever e ¹ , Fig. 2, lifts through a thumb e. the ends of the two levers e ² e ³ , Fig. 12 and 13, which ^{together form a pair of pliers, which are rotatable about the pins e 4} e ⁵ attached to the frame, in such a way that the jaws of the pliers from the funnel n> ¹ removed. This operation occurs before the cut sleeve is prepunched, while when the sleeve is in place, the forceps are closed by the action of a spring e ⁶ and clamps the sleeves on the attachment tube; then the forceps are opened again and the tube filled with tobacco, ie the cigarette, is removed by means of the stuffing pin, as described further below.

Distribution and compression

of tobacco.

The distribution and compression of the tobacco are accomplished by known means. The cam plate m gives the press slide m ² the necessary movements, ie upwards, downwards, forwards and backwards, as I have already done earlier with machines of this type. The cam plate W ¹ causes the tobacco to be fed in, and the toothed wheel η moves the endless tobacco feed cloth n ¹ and the endless cloth n ^2, which is used to distribute the tobacco evenly, through an endless chain and wheel transmission .

These distributing and pressing organs have finished a roll of tobacco when a tube has been pushed onto the extension tube n> ^x , so that the finished roll can be pushed by the stuffing mandrel c ¹ into the held tube.

Filling the pods.

The appropriately guided tamper c ¹ is moved straight back and forth and intermittently by the lever c ² from the cam disc c , as is necessary to push the tobacco roll from the press into the sleeve held on the neck tube n> ^1. When the filling of the sleeve is done, the pusher c ¹ is inhibited until the. Forceps has opened, then he continues his forward movement by about a centimeter in order to stab the cigarette off the neck tube n> ¹ , and then goes back to its starting position.

The cigarette produced in this way reaches the next movement of the rods / ¹ Z ^'2 further downwards and falls into a channel y, where the same is performed by the packaging device Z ^1/2, Fig. I.

Packing the cigarettes.
As the cigarettes arrive at / ', they are pushed forward in a known manner by means of a slide moved by the thumb / and a lever and packed into the box I ^2.

How the machine works.

The various operations just described are carried out in a regular manner in such a way that a cigarette is made with each revolution of shafts b and k .

While not glued sleeve is made of Tabaksvertheil- and Prefsmechanismus prepares a requisite for filling the sleeve tobacco wrap front, such that if a sleeve is moved down to the transport bars to a rung, BEZW a cigarette from the hopper w. the neck tube η> ^{λ has been} pushed away and a cigarette has been packed into the box. In short, all the tools and mechanisms which produce the cigarette have motions combined in such a way that the manufacture of the sleeves and their transport are in proper correlation with the processing of the tobacco. . . ..
