PATENTAMT.PATENT OFFICE.

Der Zweck dieser Erfindung ist die Construction einer Maschine für die Herstellung von Metallkapseln von jeder beliebigen Gröfse.The purpose of this invention is to build a machine for manufacturing of metal capsules of any size.

Aufser dem Bewegungsmechanismus besteht diese Maschine aus drei mit einander zusammenwirkenden Haupttheilen, und zwar:In addition to the movement mechanism, this machine consists of three interacting Main parts, namely:

I. aus dem Druckapparat, welcher die Kapseln aus dem Arbeitsblech preist;I. from the pressure apparatus, which praises the capsules from the work sheet;

II. aus dem Schieberapparat zum Verschieben des Arbeitsbleches nach dem Druckapparat; undII. From the pusher device for moving the work sheet to the pressure device; and

HI. aus dem Apparat zum Fertigmachen und Abschneiden der geprefsten Kapseln und zur Entfernung derselben aus der Maschine.HI. from the apparatus for preparing and cutting off the pressed capsules and for Removal of the same from the machine.

In den beiliegenden Zeichnungen ist Fig. 1 eine Vorderansicht dieser Maschine; Fig. 2 giebt die Seitenansicht der Bewegungsvorrichtung des Apparates unter III.; Fig. 3 ist ein Längsschnitt der Maschine; Fig. 4 giebt die Details des Apparates 'unter III., und Fig. 5 und 6 geben die Details des Apparates unter II. Die Fig. 7 und 8 zeigen die Einrichtung der Stempel des Druckapparates.In the accompanying drawings, Fig. 1 is a front view of this machine; Fig. 2 gives the side view of the movement device of the apparatus under III .; Fig. 3 is a Longitudinal section of the machine; Fig. 4 gives the details of the apparatus under III., And Fig. 5 6 and 6 give the details of the apparatus under II. FIGS. 7 and 8 show the arrangement of FIG Stamp of the printing apparatus.

Die Maschine wird durch die unten am Gestell S angebrachte Trieb welle α in Bewegung gebracht; diese Triebwelle trägt aufserhalb des Gestelles einerseits die Riemscheibe c, andererseits die Kurbel d. Zur Arikupplung der Riemscheibe dient eine Frictionskupplung y, welche mittelst der Schraube \ regulirt wird. Durch die Pleuelstange ρ wird die Bewegung der Triebwelle α von der Kurbel d an den Apparat unter III. übertragen.The machine is brought into motion by the drive shaft α attached to the frame S below; this drive shaft carries the pulley c on the one hand outside the frame and the crank d on the other hand. A friction clutch y, which is regulated by means of the screw \, serves to clutch the pulley. The movement of the drive shaft α from the crank d to the apparatus under III is controlled by the connecting rod ρ. transfer.

Die Apparate unter I. und II. werden aber durch eine senkrechte Achse a³ in Bewegung gebracht, welche Achse unten ein konisches Zahnrad b'², Fig. 3, trägt, in Eingriff mit einem ähnlichen, an der Achse α innerhalb des Gestelles S befindlichen Rad b. The apparatus under I. and II., But are brought by a vertical axis a ³ in motion, which axis below a conical gear wheel b ^'2, Fig. 3, carries α in mesh with a similar, to the axle within the rack S wheel b.

Der Druckapparat besteht hauptsächlich aus einer Anzahl in einander verschiebbarer röhrenförmiger Stempel ss'i²i³s', Fig. 1 und 3, von welchen jeder eine auf- und niedergehende Bewegung dadurch erhält, dafs die oberen Enden mit den Kloben k² vereinigt sind, welche hinten kleine Führungsrollen tragen. Diese Rollen gleiten in den Führungsrinnen XX¹X²X³X⁴ des oben an der Achse α³ angebrachten Cylinders e. The pressure apparatus consists mainly of a number of telescoping tubular dies ss'i ² i ³ s', Figs. 1 and 3, each of which is given an up and down movement by the fact that the upper ends are united with the clamps k ² which carry small guide rollers at the back. These rollers slide in the guide channels XX ¹ X ² X ³ X ^{4 of} the cylinder e attached to the top of the axis α ^3.

Diese Rinnen haben je vier verschiedene Strecken, oben und unten sind dieselben horizontal durch verschieden steigende Theile verbunden, Fig. i. Jede obere Rinne steigt etwas steiler als die ihr nächst liegende untere, während die abwärts führenden Zweige parallel sind. Durch diese Einrichtung werden die zugehörigen Stempel beim Hinuntergehen sich mit derselben Geschwindigkeit bewegen, in ihrer tiefsten Lage so lange stehen bleiben, bis die Führungsrollen den horizontalen Theil ihrer Bahnen passirt haben.These gutters each have four different routes, the top and bottom are the same horizontal connected by differently increasing parts, Fig. i. Each upper gutter rises a little steeper than the lower one lying closest to it, while the branches leading downwards are parallel are. Through this facility, the associated stamps are turned down as you go down move at the same speed, stay in their lowest position for so long, until the guide rollers have passed the horizontal part of their tracks.

Die Führungsrinnen sind aber von ungleicher Länge, derart, dafs von jeder oberen Rinne der hinabführende Zweig länger, der horizontale aber kürzer ist als die entsprechenden· Zweige der nächsten Rinne; infolge dessen dauert die Bewegung jedes oberen Stempels noch fort, nachdem der untere in Ruhe ist; es wird also jeder Stempel tiefer hinuntergeführt als der vorhergehende. Nachdem der letzte Stempel seine tiefste Lage erreicht hat, werden die Führungsrollen der Stempel gleich-The guide troughs are of unequal length, however, in such a way that from each upper trough the branch leading downwards is longer, but the horizontal one is shorter than the corresponding Branches of the next gutter; as a result, each upper punch continues to move still away after the lower one is at rest; so each punch is led down deeper than the previous one. After the last punch has reached its lowest position, the guide rollers of the punches are

zeitig in den aufwärts steigenden Bahnen der Rinnen eintreten, deren Steigungen derartig bemessen sind, dafs alle Stempel gleichzeitig ihre höchsten Punkte erreichen. Während der Auf- und Abwärtsbewegungen werden die Stempel durch die Führungsleisten«, Fig. i, 7 und 8, dirigirt, in welchen die Kloben k'², Fig. 3, der Stempel laufen; diese Führungsleisten sind um die Scharniere y^l drehbar, damit man, wenn nöthig, die Stempel leicht herausnehmen und austauschen könne.enter early in the ascending tracks of the gutters, the slopes of which are such that all pistons reach their highest points at the same time. During the upward and downward movements, the rams are directed by the guide strips ¹ , 7 and 8, in which the clamps k, 2, Fig. 3, of the ram run; these guide strips can be rotated about the hinges y ^l , so that, if necessary, the stamps can easily be removed and exchanged.

Die Führungsleisten sind von einem vom Gestell S ausragenden Arm ν getragen. Unterhalb dieses Armes befindet sich noch ein zweiter Arm, zwei senkrechte Wände.?, Fig. 7, tragend, in welchen mehrere horizontale Furchen angebracht sind, welche die den Stempeln entsprechenden Gesenke oder Matrizen u u¹ M² u^z u^l aufnehmen.The guide strips are carried by an arm ν protruding from the frame S. Below this arm there is a second arm, supporting two vertical walls.?, Fig. 7, in which several horizontal grooves are made, which receive the dies or dies corresponding to the punches uu ¹ M ² u ^z u ^l.

Diese Furchen haben eine solche Weite, dafs sie eine kleine Verschiebung der Matrizen nach allen Richtungen hin in der Horizontalebene gestatten. Demzufolge wird jede Matrize automatisch ganz genau gegen den ihr zugehörigen Stempel centrirt, welcher also beim Hinuntergehen die konische Oeffnung, »das Auge«, Fig. 7 und 8, in der Matrize genau in der Mitte passirt. Durch diese Einrichtung erleiden die Kapseln während des Formens keinen ungleichen Druck, während sonst leicht ein -Aufreifsen eintreten könnte. Der Apparat unter II., »der Schieberapparat«, Fig. 5 und 6, ist unterhalb des Cylinders e placirt und erhält seine Bewegung durch eine an der senkrechten Achse a³ befindliche Excenterscheibe 2. In dem Rande dieser Scheibe befindet sich eine Führungsrinne, in welcher ein Zapfen des Schieberarmes 1 gleitet, Fig. 6. Dieser Zapfen wird durch eine Spiralfeder, welche das entsprechende Ende des Schieberarmes mit dem Gestell vereinigt, in die Rinne jener Scheibe eingedrückt. Der Schieberarm ruht in der Mitte auf einem doppelgelenkigen, am Gestell befestigten Zapfen, um welchen der Arm sich frei bewegen kann. Am anderen Ende des Armes befindet sich eine verschiebbare Gabel 3, deren Arm 4 eine in dem Arbeitstisch jf'² befindliche bewegliche Scheibe 5 umfassen, welche nebst der an dem oberen Arm befindlichen Scheibe 11 den zu bearbeitenden Blechstreifen hervorschiebt.These furrows are so wide that they permit a slight displacement of the matrices in all directions in the horizontal plane. As a result, every die is automatically centered exactly against the punch belonging to it, which, when going down, passes the conical opening, "the eye", Fig. 7 and 8, in the die exactly in the middle. As a result of this device, the capsules do not suffer any unequal pressure during molding, while otherwise they could easily be opened. The apparatus under II., "The slide apparatus", FIGS. 5 and 6, is placed below the cylinder e and is moved by an eccentric disk 2 located on the vertical axis a ^3. In the edge of this disk there is a guide channel, in which a pin of the slide arm 1 slides, Fig. 6. This pin is pressed into the groove of that disk by a spiral spring which unites the corresponding end of the slide arm with the frame. The pusher arm rests in the middle on a double-jointed pin attached to the frame, around which the arm can move freely. At the other end of the arm there is a movable fork 3, the arm 4 comprise a jf in the work table ² 'located movable disc 5, which pushes the projecting together with the on-the upper arm plate 11 to be machined sheet metal strip.

Die Führungsrinne der Excenterscheibe 2 ist derart geformt, dafs sie dem Zapfen des Schieberarmes eine Bewegung sowohl in horizontaler als in verticaler Richtung mittheilt, , welche Bewegung nach dem Schieberarm übertragen wird. Zufolge der Befestigung des Schieberarmes in der Mitte wird diese Bewegung an das Vorderende des Schieberarmes derart überführt, dafs der obere Gabelarm und die damit verbundene Scheibe 11 bei ihrer von den Stempeln am meisten entfernten Stellung gegen das Arbeitsblech geprefst werden, welches zwischen der von dem oberen Gabelarm niedergedrückten Scheibe 1 1 und der in dem Arbeitstisch befindlichen beweglichen Scheibe 5 hineingeschoben wird. Bei der weiteren Bewegung der Excenterscheibe 2 wird die Gabel nebst der Scheibe 5 und dem zwischenliegenden Blechstreifen gegen die Stempel hervorgeschoben, wobei der Blechstreifen von der oberhalb des Arbeitstisches angebrachten Rolle v^l abgewickelt und sein Vorderende unter die Stempel geschoben wird.The guide groove of the eccentric disk 2 is shaped in such a way that it notifies the pin of the slide arm a movement both in the horizontal and in the vertical direction, which movement is transmitted to the slide arm. As a result of the fastening of the pusher arm in the middle, this movement is transferred to the front end of the pusher arm in such a way that the upper fork arm and the disk 11 connected to it are pressed against the work sheet in their position furthest away from the punches, which is between that of the upper fork arm Fork arm depressed disc 1 1 and located in the work table movable disc 5 is pushed in. As the eccentric disk 2 continues to move, the fork, along with the disk 5 and the sheet metal strip lying in between, is pushed out against the punch, the sheet metal strip being unwound from the roll v ^l attached above the work table and its front end being pushed under the punch.

Infolge der Form der Führungsrinne der Excenterscheibe 2 hört aber in diesem Augenblick der Druck der Gabel gegen den Blechstreifen auf; durch die Einwirkung der Spiralfeder auf das Hinterende des Schieberarmes wird dieser in seine frühere Lage zurückgeführt; die mit dem unteren Gabelarm 4 verbundene Scheibe 5 und die an der oberen Zacke befestigte Scheibe 11 nehmen an dieser Bewegung Theil.As a result of the shape of the guide groove of the eccentric disc 2 stops at this moment the pressure of the fork against the metal strip; by the action of the spiral spring on the rear end of the pusher arm this is returned to its previous position; the disk 5 connected to the lower fork arm 4 and the disk 11 attached to the upper prong take this Movement part.

In dem Arbeitstisch befinden sich mehrere verstellbare Riegel, durch welche die Länge des Vorschiebens und des Zurückweichens der Scheibe 5 und somit auch das jeweilige Hervorschieben des Blechstreifens auf das genaueste regulirt werden kann.In the work table there are several adjustable latches, through which the length the advancing and retreating of the disc 5 and thus also the respective pushing out of the sheet metal strip can be regulated as precisely as possible.

Sobald der Blechstreifen unter die Stempel eingeschoben worden ist, fangen diese an, sich abwärts zu bewegen. Zuerst wird dann eine kreisrunde Scheibe ausgepunzt, aus welcher die Kapsel geformt werden soll, dann wird die Kapsel allmälig in die Länge gezogen, je nachdem sie von den folgenden Stempeln durch die entsprechenden »Augen« in den Matrizen u bis M⁴ geprefst wird. Nach dem Passiren der letzten Matrize wird die Kapsel dem Vollendungsapparat unter III. übergeben, was durch einen in dem letzten Stempel eingeschlossenen Schieber y^ geschieht. In dem Augenblick des Uebergebens wird nämlich dieser Schieber durch einen oben an der senkrechten Achse α³ hervorragenden Arm f momentan nach unten geschoben.As soon as the metal strip has been pushed under the punches, they begin to move downwards. First a circular disc is punched out of which the capsule is to be formed, then the capsule is gradually elongated as it is pressed through the corresponding "eyes" in the dies u to M ^{4 by the following punches.} After passing the last die, the capsule is given to the completion apparatus under III. passed what happens through a slide y ^ enclosed in the last punch. At the moment of transfer, namely, this slide is momentarily pushed downwards by an arm f ^{protruding above the vertical axis α 3.}

Der Vollendungsapparat, Fig. 2 und 4, besteht aus zwei über einander placirten und gegenseitig zusammenwirkenden Theilen, von welchen der obere die Kapsel dem Druckapparat abnimmt und sie an den unteren Theil übergiebt, wo die Kapsel geebnet und am Rande sauber geschnitten wird, um danach abgeliefert zu werden.The completion apparatus, Figs. 2 and 4, consists of two placed on top of each other and mutually cooperating parts, of which the upper part is the capsule to the pressure apparatus decreases and transfers it to the lower part, where the capsule is leveled and cut neatly at the edge, and afterwards to be delivered.

Die Theile des Vollendungsapparates werden von separaten Achsen a¹ bezw. a² getragen und stehen 'durch Zahnräder g g¹ in dem Auswechselungsverhältnifs 1 : 2 zu einander. Demzufolge macht die untere Achse a¹ eine ganze Umdrehung, während die obere a² nur eine halbe macht. Der Vollendungsapparat er-The parts of the completion apparatus are separated by separate axes a ¹ respectively. a ² carried and are 'by gears gg ¹ in the exchange ratio 1: 2 to each other. As a result, the lower axis a ¹ makes a full turn, while the upper a ² makes only half a revolution. The completion apparatus

keeps its movement through the upper axis ar by means of the gear n ^l attached to the end thereof and the oscillating toothed arc o, which is connected to the axis a by the connecting rod ρ and the crank d . The axis a ² is brought to participate in the forward movement of the dental arch o by the action of the locking hook X ^s . The locking hook is attached to the arm η connected to the freely movable gear n ¹ and engages alternately in one of the two notches made in the wheel m attached to the axis a ^2. As a result, the axle will make half a turn every time the locking hook X ^s engages one of the notches. After each half revolution but the movement of the axis a 'is ² q inhibited by the bolt mounted on the frame, which is / pushed into a recess in the α to the axle ² adjacent to the ratchet wheel attached Riegelrad m by a spring. The bolt q remains in this position until the dental arch ο has completed its backward movement; but then the locking hook x ^{5 takes} its position behind the bolt q in order to remove it during its subsequent forward movement. to remove the recess. The locking hook now engages directly in the next notch in the wheel m in order to rotate the axis d ² by 180 °.

At the inner end of the axis α ² and just below the dies there is a tube r whose longitudinal axis coincides with that of the punches as soon as the axis α ^{2 is} at rest. In this tube there is a cylindrical slide r ¹ . As soon as the capsule has passed the matrices and leaves the pressure apparatus, it is pushed into the upper mouth of the receiving tube r of the completion apparatus, which is then reversed by the mechanism described above so that its upper mouth comes down. The following capsule is pushed into the empty mouth, which is now facing upwards (formerly the lower one) and pushes the movable cylinder r ¹ downwards, which consequently pushes the capsule there out and places it on the mouthpiece i , which is located on that of the lower one Axis a ¹ carried part of the perfection apparatus is located.

The axis a ^l carries at its inner end, just below the receiving tube r, a tube h ^l , which is fixed perpendicular to the axis. This tube encloses a spindle h , one end of which carries the mouthpiece i , while a conical gear wheel k sits on the other, which engages in a similar wheel k ^{l located on the frame.} According to this device, the spindle h assumes a rotating movement about its axis for every complete revolution of the lower axis a ¹ . On an arm protruding from the tube A ¹ there is the movable socket g · ² with the handle 7, which carries a piece of leather as a polishing agent, with which it smooths the capsule stuck on it when the mouthpiece is rotated. At the lower edge of the same handle 7 there is the cutting edge 8 which is directed towards the mouthpiece and which can be pressed against its lower edge. This is achieved in that the socket g ² connected to the handle is continuously pressed by a spiral spring against the inner surface of the toothed disk k ^l on the frame, the inside of which is partially provided with a guide rail. As soon as the completion apparatus begins its work, the front part of the socket g ¹ leaves this rail and slides down on the disk k ^x . By the action of the spiral spring, the socket is pressed against the disk surface and the cutting edge 8 is pressed against the lower edge of the mouthpiece i , so the capsule is cut off sharply at the bottom. The cutting edge is then removed from the mouthpiece i in that the front part of the socket g ² again slides up onto the guide rail.

The removal of the cut-off capsule hoop would be impossible if it were not broken through somehow. For this purpose the tube A ¹ , FIG. 4, has two cutting edges which, at the very moment when the capsule is attached to the mouthpiece i , make two vertical cuts below. In the section through the cutting edges 8 that now follows, the cut edge therefore falls into two halves and cannot get stuck on the spindle A. The fully finished capsule is finally ejected from the mouthpiece by the pressure of a slide y ^{z enclosed in this spindle A;} When the tube A ¹ rotates, this slide is pushed forward by the pressure of an arm protruding from the frame and consequently throws the capsule loose.

The residues of the processed sheet metal strip can be removed from the channel y ^{l at} will.
