Description

Die Erfindung betrifft eine Vorrichtung zum Ausrichten der Öffnungsseiten von Hohlkörper mit annähernd zylindrischer Grundform, die einseitig einen Abschluß als ganz oder teilweise geschlossener Boden oder eine Formkontraktion aufweisen und deren größter Querschnittsdurchmesser wesentlich kleiner als ihre Längserstreckung ist, wobei ein Kanal zum Transport der Hohlkörper und ein Schwenkmechanismus für einen in den Kanal ragenden Stift vorhanden ist, mit Hilfe des Stiftes erkennbar ist, ob der Abschluß an der Unterseite des Hohlkörpers ist oder nicht, und nur solche Hohlkörper, deren Abschluß an der Unterseite der Hohlkörper ist, nach Wegschwenken des Stiftes geordnet weiterfallen können.The invention relates to a device for aligning the opening sides of hollow bodies with an approximately cylindrical basic shape, which have a closure on one side as a completely or partially closed bottom or a shape contraction and whose largest cross-sectional diameter is significantly smaller than its longitudinal extent, with a channel for transporting the hollow bodies and a Swivel mechanism for a pin protruding into the channel is present, with the help of the pin it can be seen whether the closure is on the underside of the hollow body or not, and only those hollow bodies whose closure is on the underside of the hollow body continue to fall in an orderly manner after the pin has been swung away can.

Die Hülsen für Sprengkapseln, Munition u. dgl. werden getrennt von dem Hülseninhalt hergestellt und der Hülseninhalt wird erst anschließend in die fertigen Hülsen eingesetzt. Die Hülsen liegen nach ihrer Herstellung regellos vor, und sie müssen nicht nur axial ausgerichtet werden, sondern ihr Hülsenboden muß auch in eine definierte Position gebracht werden, bevor die Weiterverarbeitung erfolgen kann.The sleeves for detonators, ammunition and. The like. Are produced separately from the sleeve content and the sleeve content is only then inserted into the finished sleeves. The sleeves are randomly available after their manufacture, and they not only have to be aligned axially, but their sleeve bottom must also be brought into a defined position before further processing can take place.

Es ist bekannt, Hülsen zum Zwecke der Ausrichtung des Hülsenbodens auf eine Art Waagebalken zu befördern, so daß diejenige Hälfte des Balkens, auf der sich der Hülsenboden befindet, aufgrund ihres größeren Gewichtes absinkt. Weiterhin ist es bekannt, Hülsen auf eine schiefe Ebene, in der parallele Nuten angeordnet sind, durch Schütteln axial auszurichten. Die an den unteren Enden ankommenden Hülsen werden, sofern sie mit ihren Öffnungen zuerst ankommen, auf Nocken gestülpt, um anschließend durch ihr Gewicht mit dem Boden nach unten herunterzufallen. Die Hülsen, die mit dem Boden zuerst ankommen, stoßen gegen die Nocken und fallen sofort in die Auffangtrichter.It is known to transport sleeves for the purpose of aligning the sleeve base on a type of balance beam, so that that half of the beam on which the sleeve base is located sinks due to its greater weight. Furthermore, it is known to axially align sleeves on an inclined plane, in which parallel grooves are arranged, by shaking. The sleeves arriving at the lower ends, if they arrive with their openings first, are put on cams and then fall down with their weight due to their weight. The pods that arrive first with the bottom hit the cams and immediately fall into the collecting funnels.

Bei den bekannten Verfahren zum Ausrichten der Hülsenböden wird die Schwerpunktlage der Hülse zum Wenden ausgenutzt. Diese Verfahren sind nicht hinreichend sicher, so daß sowohl Fehlausrichtungen als auch Verklemmungen vorkommen können.In the known methods for aligning the sleeve bottoms, the center of gravity of the sleeve is used for turning. These procedures are not sufficiently secure, so that misalignments as well as jams can occur.

In der US-A-2 364 243 ist eine Sortier- und Ausrichteinrichtung für Patronenhülsen beschrieben, bei der in ein gekrümmtes Rohr ein schwenkbarer Stift hineinragt. Wenn eine Hülse mit dem Boden nach unten durch das Rohr rutscht, drückt sie den Stift zur Seite und rutscht dann im Rohr weiter. Fällt dagegen eine Hülse mit ihrer Näpfchenseite auf den Stift, bleibt sie zunächst an dem Stift « hängen ", diese Hülse wird durch den ausschwenkenden Stift aus dem Rohr herausgezogen und fällt in einen Sammelbehälter. Bei dieser Vorrichtung erfolgt kein Umdrehen der falsch im Zuführkanal liegenden Hülsen sondern nur ein Aussortieren. Kritisch ist dabei die Sortiergenauigkeit; daneben stört die geringe Leistungsfähigkeit und der Wartungsaufwand.US-A-2 364 243 describes a sorting and aligning device for cartridge cases in which a pivotable pin projects into a curved tube. When a sleeve slides through the tube with the bottom down, it pushes the pin to the side and then continues to slide in the tube. If, on the other hand, a sleeve falls with its well side onto the pin, it initially "catches " on the pin, this sleeve is pulled out of the tube by the pivoting pin and falls into a collecting container. With this device, the sleeves lying incorrectly in the feed channel are not turned over The only thing that is critical is the accuracy of the sorting, and the low performance and the maintenance effort are also a problem.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der eine Abtastung des Hülsenbodens und in Abhängigkeit von dem Ergebnis der Abtastung erforderlichenfalls ein zwangsweises Wenden der Hülse ohne Ausnutzung der Lage des Hülsenschwerpunktes erfolgt.The invention has for its object to provide a device of the type mentioned, in which a scanning of the sleeve base and, depending on the result of the scanning, if necessary, a forced turning of the sleeve without utilizing the position of the sleeve center of gravity.

Die Lösung der Aufgabe besteht erfindungsgemäß darin, daß eine drehschwenkende Sortierwalze vorgesehen ist, auf deren Umfangsfläche mindestens ein Zuführkanal mündet, daß die Sortierwalze in der Querebene jedes Zuführkanals in einer Schwenkposition je einen Durchgangskanal und in einer anderen Schwenkposition je einen Sperrkanal aufweist, Durchgangskanal und Sperrkanal parallel zueinander und mit gleichen Abständen von der Drehachse der Sortierwalze verlaufen, der Sperrkanal als Sacklochbohrung ausgebildet ist, wobei vom Boden der Sacklochbohrung her der Stift, dessen Durchmesser so groß ist, daß er den Abschluß der auszurichtenden Hohlkörper nicht durchdringen kann, koaxial durch den Sperrkanal bis zur Umfangsfläche der Walze ragt und daß von der vom Zuführkanal abgewandten Seite der Sortierwalze mindestens ein Auslaßkanal zum Abführen der gleichgerichteten Hohlkörper abgeht.The object of the invention is that a rotating pivoting sorting roller is provided, on the circumferential surface of which at least one feed channel opens, that the sorting roller in the transverse plane of each feed channel has a passage channel in a pivot position and a blocking channel in a different pivot position, through channel and blocking channel run parallel to each other and at equal distances from the axis of rotation of the sorting roller, the blocking channel is designed as a blind hole, whereby from the bottom of the blind hole the pin, the diameter of which is so large that it cannot penetrate the end of the hollow body to be aligned, coaxially through the blocking channel extends to the circumferential surface of the roller and that at least one outlet channel extends from the side of the sorting roller facing away from the feed channel for discharging the rectified hollow bodies.

Bei der erfindungsgemäßen Vorrichtung befindet sich in der Aufnahmestellung der Sortierwalze der Sperrkanal in Ausrichtung mit dem Zuführkanal. Diejenigen Hohlkörper, die mit der Öffnung zuerst ankommen, dringen in den Sperrkanal ein, jedoch wird der Hülsenboden beim Anschlagen gegen das Ende des Stiftes an der Weiterbewegung gehindert.In the device according to the invention, the blocking channel is in the receiving position of the sorting roller in alignment with the feed channel. Those hollow bodies that arrive first with the opening penetrate into the blocking channel, but the sleeve base is prevented from moving further when it strikes against the end of the pin.

Beim nachfolgenden Drehschwenken der Sortierwalze um ihre Längsachse herum werden diese Hohlkörper gewendet, so daß sie mit dem Boden zuerst aus der Sortierwalze herausfallen. Diejenigen Hohlkörper, die mit dem Boden zuerst ankommen, stoßen mit dem Boden gegen das Ende des Stiftes, so daß sie überhaupt nicht in die Sortierwalze eindringen können. Beim Drehschwenken der Sortierwalze gelangt der Durchgangskanal in Ausrichtung mit dem Zuführkanal, so daß diese Hohlkörper durch den Durchgangskanal hindurch in den Auslaßkanal befördert werden. Somit werden sämtliche Hohlkörper, unabhängig davon, ob sie mit dem Boden oder der Öffnung ankommen, mit dem Boden voran in den Auslaßkanal befördert.During the subsequent pivoting of the sorting roller about its longitudinal axis, these hollow bodies are turned so that they fall out of the sorting roller with the bottom first. Those hollow bodies that arrive first with the bottom hit the bottom against the end of the pin so that they cannot penetrate the sorting roller at all. When the sorting roller is pivoted, the through channel comes into alignment with the feed channel, so that these hollow bodies are conveyed through the through channel into the outlet channel. Thus, all hollow bodies, regardless of whether they arrive with the bottom or the opening, are conveyed face down into the outlet channel.

Ein besonderer Vorteil der erfindungsgemäßen Vorrichtung besteht darin, daß sie unterschiedliche Hohlkörperlängen verarbeiten kann, ohne daß an der Vorrichtung Veränderungen oder Justierungen vorgenommen werden müßten. Auch Hohlkörper mit unterschiedlichen Durchmessern können in gleicher Weise verarbeitet werden.A particular advantage of the device according to the invention is that it can process different lengths of hollow body without changes or adjustments having to be made to the device. Hollow bodies with different diameters can also be processed in the same way.

Das Einfüllen der Hohlkörper in die Sortierwalze und das Herausführen aus der Sortierwalze erfolgt vorzugsweise durch Schwerkraft, wobei die Sortierwalze mit horizontaler Achse angeordnet ist und der Zuführkanal und der Auslaßkanal im wesentlichen vertikalen Verlauf haben. Es ist aber auch möglich, das Zuführen und Abführen unabhängig von der Schwerkraft, z. B. mit Hilfe von Druckluft, vorzunehmen.The filling of the hollow bodies into the sorting roller and the removal from the sorting roller is preferably carried out by gravity, the sorting roller being arranged with a horizontal axis is and the supply channel and the outlet channel have a substantially vertical course. But it is also possible to feed and discharge regardless of gravity, for. B. using compressed air.

Vorzugsweise ist eine Sortierwalze für mehrere Zuführkanäle ausgelegt, wobei die einzelnen Zuführkanäle achsparallel zur Sortierwalze auf deren Umfangsfläche enden. Durchgangskanal und Sperrkanal haben dann in jeder Querebene die gleichen Abstände von der Drehachse der Sortierwalze.A sorting roller is preferably designed for a plurality of feed channels, the individual feed channels ending axially parallel to the sorting roller on its circumferential surface. Through channel and blocking channel then have the same distances from the axis of rotation of the sorting roller in each transverse plane.

Vorzugsweise ist der einzige Auslaßkanal trichterförmig ausgebildet und mit seinem größeren Ende der Sortierwalze zugewandt und das größere Ende erfaßt sowohl den Durchgangskanal als auch den Sperrkanat, wenn der Durchgangskanal mit dem Zuführkanal fluchtet. Hierbei ist nur ein einziger Auslaßkanal für den Durchgangskanal und für den Sperrkanal erforderlich. Alternativ besteht auch die Möglichkeit, zwei getrennte Auslaßkanäle vorzusehen, die später wieder vereinigt werden.The single outlet channel is preferably funnel-shaped and faces the sorting roller with its larger end, and the larger end detects both the through channel and the blocking channel when the through channel is aligned with the feed channel. Only a single outlet channel is required for the through-channel and for the blocking channel. Alternatively, there is also the possibility of providing two separate outlet channels, which are later reunited.

Im folgenden wird unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert.In the following an embodiment of the invention will be explained with reference to the drawings.

  • Fign. 2 bis 6 einen Querschnitt durch die Sortierwalze in verschiedenen Betriebszuständen.
Show it :
  • Fig. 1 is a schematic perspective view of the device for aligning sleeves and
  • Fig. 2 to 6 a cross section through the sorting roller in different operating states.

Die Vorrichtung zum Ausrichten von Hülsen weist ein Gestell 10 auf, an dessen oberem Ende ein um eine horizontale Achse 11 schwenkbarer Zuführbehälter 12 angeordnet ist. Der Zuführbehälter 12 ist an seiner Oberseite offen und sein Boden ist mit zahlreichen parallelen Nuten 13 versehen, die quer zur Schwenkachse 11 verlaufen und in den Auslaß 14 münden. An der Unterseite des Zuführbehälters 12 greift eine Antriebseinrichtung 15 an, um den Zuführbehälter 12 um die Achse 11 herum zu bewegen bzw. zu rütteln, damit die im Zuführbehälter 12 liegenden Hülsen sich in den Nuten 13 axial ausrichten.The device for aligning sleeves has a frame 10, on the upper end of which a swiveling feed container 12 is arranged about a horizontal axis 11. The feed container 12 is open at its top and its bottom is provided with numerous parallel grooves 13 which run transversely to the pivot axis 11 and open into the outlet 14. A drive device 15 engages on the underside of the feed container 12 in order to move or shake the feed container 12 around the axis 11 so that the sleeves lying in the feed container 12 align axially in the grooves 13.

Hinter dem Auslaß 14 des Behälters 12 ist eine Vereinzelungsvorrichtung 16 aus mehreren quer zu den Nuten 13 verlaufenden Leisten angeordnet, die einzeln geklappt werden können, um eine Reihe von Hülsen jeweils zur nächsten Leiste weiterzuleiten. Danach werden die Leisten wieder hochgeklappt, um die nächstfolgende Reihe von Hülsen zu empfangen.Behind the outlet 14 of the container 12, a separating device 16 is arranged from a plurality of strips running transversely to the grooves 13, which can be folded individually in order to forward a row of sleeves to the next strip in each case. The bars are then folded up again to receive the next row of sleeves.

Das Auslaßende der Vereinzelungsvorrichtung 16 ist mit zahlreichen parallelen Zuführkanälen 17 zum Zuführen der Hülsen zu dem Walzengehäuse 18 verbunden. Die Zuführkanäle 17 sind Schläuche oder Rohre, von denen jeder für den Durchlaß einer Hülse, die von der Vereinzelungsvorrichtung 16 freigegeben worden ist, bestimmt ist. Die Zuführkanäle 17 führen durch den oberen Bereich der Umfangswand des mit horizontaler Achse angeordneten Walzengehäuses 18 hindurch. Unter dem Walzengehäuse 18 ist ein Verteiler 20 angeordnet, aus dem zahlreiche Auslaßkanäle 22 austreten. Diese Auslaßkanäle führen zu einer Transportpalette 21 in deren Löcher die Hülsen mit nach unten gerichtetem Boden eingeführt werden.The outlet end of the separating device 16 is connected to numerous parallel feed channels 17 for feeding the sleeves to the roller housing 18. The feed channels 17 are hoses or tubes, each of which is intended for the passage of a sleeve which has been released by the separating device 16. The feed channels 17 lead through the upper region of the peripheral wall of the roller housing 18 arranged with a horizontal axis. A distributor 20 is arranged under the roller housing 18, from which numerous outlet channels 22 emerge. These outlet channels lead to a transport pallet 21 in the holes of which the sleeves are inserted with the bottom directed downwards.

Die Fign. 2 bis 6 zeigen einen Querschnitt durch die im Innern des Walzengehäuses 18 angeordnete Sortierwalze 19, die um ihre horizontale Achse herum drehbar ist. In der Querebene eines jeden Zuführkanals 17 weist die Sortierwalze 19 einen Sperrkanal 23 und einen Durchgangskanal 24 auf. Die beiden Kanäle 23 und 24 verlaufen parallel zueinander und mit gleichen Abständen von der Drehachse der Sortierwalze 19. Der Sperrkanal 23 ist als Sacklochbohrung ausgebildet, die nur an einem Ende zum Walzenumfang führt und dort offen ist, während das gegenüberliegende Ende sich im Innern der Sortierwalze befindet und verschlossen ist. Von diesem verschlossenen Ende ragt ein Stift 26 koaxial durch den Sperrkanal 23 hindurch bis zur Umfangsfläche der Walze.The figures 2 to 6 show a cross section through the sorting roller 19 arranged inside the roller housing 18, which can be rotated about its horizontal axis. In the transverse plane of each feed channel 17, the sorting roller 19 has a blocking channel 23 and a through channel 24. The two channels 23 and 24 run parallel to one another and at equal distances from the axis of rotation of the sorting roller 19. The blocking channel 23 is designed as a blind hole which only leads to the roller circumference at one end and is open there, while the opposite end is inside the sorting roller located and locked. From this closed end, a pin 26 projects coaxially through the blocking channel 23 to the circumferential surface of the roller.

In Fig. 2 ist der Fall dargestellt, daß aus dem Zuführkanal 17 eine Hülse 25 mit nach hinten gerichtetem Hülsenboden 25a ankommt, während die Sortierwalze 19 sich in der Wartestellung befindet, in der der Sperrkanal 23 mit dem Zuführkanal 17 ausgerichtet ist. Die Hülse 25 dringt in den Sperrkanal 23 ein, bis der Hülsenboden 25a gegen das freie Ende des Stiftes 26 stößt. Die Hülse 25 befindet sich dann nahezu vollständig im Innem der Sortierwalze 19, wobei sie auf dem Stift 26 aufsitzt. Lediglich der Hülsenboden 25a ragt geringfügig über die Kontur der Umfangsfläche der Sortierwalze 19 hinaus. Damit die Sortierwalze 19 in diesem Zustand gedreht werden kann, ist der Innendurchmesser des Walzengehäuses 18 an dieser Stelle geringfügig größer als der Außenumfang der Sortierwalze 19.In Fig. 2 the case is shown that a sleeve 25 arrives from the feed channel 17 with the sleeve bottom 25 a directed backwards, while the sorting roller 19 is in the waiting position in which the blocking channel 23 is aligned with the feed channel 17. The sleeve 25 penetrates into the blocking channel 23 until the sleeve bottom 25a abuts against the free end of the pin 26. The sleeve 25 is then almost completely inside the sorting roller 19, wherein it rests on the pin 26. Only the sleeve bottom 25a protrudes slightly beyond the contour of the peripheral surface of the sorting roller 19. So that the sorting roller 19 can be rotated in this state, the inner diameter of the roller housing 18 is slightly larger at this point than the outer circumference of the sorting roller 19.

Nachdem die Hülse 25 von dem Sperrkanal 23 aufgenommen wurde, wird die Sortierwalze 19 in Richtung des Pfeiles 27 gemäß Fig. 3 gedreht Nach einer Drehung um 180° befindet sich die Öffnung des Sperrkanals 23 im Bereich des trichterförmigen Auslaßkanals 22, der dem Zuführkanal 17 gegenüberliegt. Die Hülse 25 fällt jetzt, aufgrund der Schwerkraft, mit nach unten gerichtetem Hülsenboden 25 aus dem Sperrkanal 23 heraus. Anschließend wird die Sortierwalze 19 wieder zurückgedreht, bis sie den in Fign. 2 und 5 dargestellten Ausnahmezustand wieder annimmt.After the sleeve 25 has been received by the blocking channel 23, the sorting roller 19 is rotated in the direction of the arrow 27 according to FIG. 3. After a rotation by 180 °, the opening of the blocking channel 23 is in the region of the funnel-shaped outlet channel 22 which lies opposite the feed channel 17 . The sleeve 25 now falls out of the blocking channel 23 due to the force of gravity with the sleeve bottom 25 directed downward. Then the sorting roller 19 is turned back again until it is shown in FIGS. 2 and 5 assumes the exceptional state shown again.

In Fig. 5 ist der Fall dargestellt, daß eine Hülse 25 mit nach vorne gerichtetem Hülsenboden 25a auf die Sortierwalze 19 trifft. Der Hülsenboden 25a stößt gegen das Ende des Stiftes 26, so daß die Hülse 25 nicht in die Sortierwalze eindringen kann. Wird die Sortierwalze 19 anschließend um 180° gedreht, so gelangt der Durchgangskanal 24 in Ausrichtung mit dem Zuführkanal 17. Die Hülse 25, die sich bisher mit dem Boden 25a auf dem Walzenumfang abgestützt hatte, fällt nunmehr im freien Fall durch den Durchgangskanal 24, der an beiden Enden offen ist, hindurch in den Auslaßkanal 22 hinein. In der Auslaßstellung, die in denIn Fig. 5 the case is shown that a sleeve 25 with the sleeve bottom 25a facing forward hits the sorting roller 19. The sleeve base 25a abuts against the end of the pin 26, so that the sleeve 25 cannot penetrate the sorting roller. If the sorting roller 19 is then rotated through 180 °, the through-channel 24 comes into alignment with the feed channel 17. The sleeve 25, which previously had been supported on the circumference of the roller with the bottom 25a, now falls in free fall through the through-channel 24 is open at both ends, into the outlet channel 22. In the outlet position, which in the

Fign. 4 und 6 dargestellt ist, erfaßt der trichterförmige Auslaßkanal 22 die Öffnungen des Sperrkanals 23 und des Durchgangskanals 24. In der Auslaßstellung verläßt die Hülse 25 mit nach vorne weisendem Hülsenboden 25a die Sortierwalze 19 - unabhängig davon, ob sie gemäß Fig. 2 mit zurückweisendem Boden oder gemäß Fig. 5 mit nach vorne weisendem Boden angekommen ist. Anschließend wird die Sorierwalze 19 wieder zurückgedreht.Fig. 4 and 6, the funnel-shaped outlet channel 22 detects the openings of the ratchet nals 23 and the through-channel 24. In the outlet position, the sleeve 25 leaves the sorting roller 19 with the sleeve bottom 25 a facing forward - regardless of whether it has arrived according to FIG. 2 with a rejecting bottom or according to FIG. 5 with a forward facing bottom. The sorter roller 19 is then turned back again.

Die Hülsen werden regellos in den Zuführbehälter 12 gemäß Fig. 1 eingefüllt. Anschließend wird die Antriebseinrichtung 15 mehrere Male betätigt, um die Hülsen zu schütteln und in den Nuten 13 auszurichten. Bei schrägstehendem Behälterboden wird dann die Antriebseinrichtung 15 angehalten und eine Hülsenreihe nach der nächsten wird über die Vereinzelungsvorrichtung 16 den Zuführkanälen 17 zugeführt. Für jeden Zuführkanal 17 weist die Sortierwalze 19 einen Sperrkanal 23 und einen Durchgangskanal 24 auf. Die Hülsen 25, die die Sortierwalze mit nach unten gerichtetem Boden verlassen, werden durch die Auslaßkanäle 22 in die Löcher der Transportpalette 21 geleitet.The sleeves are randomly filled into the feed container 12 according to FIG. 1. The drive device 15 is then actuated several times in order to shake the sleeves and align them in the grooves 13. When the container bottom is inclined, the drive device 15 is then stopped and one row of sleeves after the next is fed to the feed channels 17 via the separating device 16. For each feed channel 17, the sorting roller 19 has a blocking channel 23 and a through channel 24. The sleeves 25, which leave the sorting roller with the bottom directed downward, are passed through the outlet channels 22 into the holes in the transport pallet 21.
