Description

Vorrichtung zum Transportieren und Stapeln von Blechen Die Erfindung betrifft eine Vorrichtung zum Transportieren und Stapeln von Blechen mittels Magnetrollen, bei der die ankommenden Bleche mit gleichbleibender Geschwindigkeit in gleicher Höhe übernormen und weitergeleitet oder unter der Vorrichtung gestapelt werden.Device for transporting and stacking sheets The invention relates to a device for transporting and stacking metal sheets by means of magnetic rollers, in which the incoming sheets at a constant speed in the same Above standard height and forwarded or stacked under the device.

Bei den bekannten Vorrichtungen zum Transportieren und Stapeln von Blechen finden Magnetkrane Verwendung, die an Traversen hängende reckteckige oder runde Plattenmagnete tragen, mit denen die Bleche aufgenommen, weitergetragen und wieder abgelegt werden. Mit diesen Vorrichtungen lassen sich die auf einem Rollgang ankommenden Bleche nicht mit gleichbleibender Geschwindigkeit übernehmen und weiterleiten, vielmehr muß der Rollgang mit den aufzunehmenden Blechen jeweils stillgesetzt werden. Ferner sind in der Höhe verstellbare rechteckige oder runde Plattenmagnete bekannt, unter denen ein in der Höhe nicht verstellbares Band läuft. Diese Vorrichtungen stellen Weichen in der senkrechten Ebene dar und haben den Nachteil, daß zwischen den Magneten und dem zu transportierenden Blech in jedem Fall ein großer, die Tragkraft mindernde Luftspalt besteht. In the known devices for transporting and stacking Sheet metal is used for magnetic cranes, the rectangular or Carry round plate magnets with which the sheets are picked up, carried on and be put down again. These devices can be used on a roller table do not take over and forward incoming sheets at a constant speed, rather, the roller table with the sheets to be picked up must be stopped in each case. Furthermore, height-adjustable rectangular or round plate magnets are known, under which a height-adjustable belt runs. These devices represent points in the vertical plane and have the disadvantage that between the magnet and the sheet metal to be transported is in any case a large one, the load-bearing capacity there is a reducing air gap.

Bekannt sind auch Magnetrollgänge, die mit Permanentmagnetrollen arbeiten. Mit diesen Rollgängen lassen sich jedoch keine Blechstapel bilden, weil die einmal gefaßten Bleche nicht abfallen. Ferner sind Rollgänge mit Elektromagnetrollen bekannt, bei denen feststehende Magnete innerhalb eines sich drehenden Rollenmantels liegen, wobei der Magneterregerstrom durch die hohle Welle zugeführt wird. Diese Rollen haben infolge des großen Luftspaltes zu große Durchmesser, um die entsprechend starken Magnete aufzunehmen. Ein weiterer Vorschlag behandelt einen Rollgang mit Magnetrollen, bei denen die Polscheibe einz im Querschnitt I-förmigen Magnets zusammen mit zwei zwischen den Polscheiben eingesetzten, unmag,netisierbaren Einlagen eine Förderwalze von zylindrischer Form bilden. In diesem Falle kommt abwechselnd nur jede zweite Rolle zum Tragen. Bei Maguetrollgängen ist aber der Rollendurchmesser und der Abstand der einzelnen Rollen von großer Bedeutung, insbesondere beim Transport von kurzen, dicken Blechen. Dabei ist nicht nur die größte Tragfähigkeit erforderlich, sondern auch ein geringer Abstand der wirksamen Berührungslinien, um ein Verlaufen der Bleche zu vermeiden. Magnetic roller tables with permanent magnet rollers are also known work. With these roller tables, however, sheet stacks cannot be formed because the once gripped sheets do not fall off. There are also roller tables with electromagnetic rollers known, in which fixed magnets within a rotating roller shell with the magnetic excitation current being supplied through the hollow shaft. These Due to the large air gap, the diameter of the rollers is too large to accommodate them accordingly strong magnets. Another suggestion deals with a roller table Magnetic rollers, in which the pole disc consists of a single magnet with an I-shaped cross-section one with two non-magnetic, netisable inserts inserted between the pole discs Form a conveyor roller of cylindrical shape. In this case just alternate every other roll to wear. In the case of Maguetrolls, however, is the roller diameter and the distance between the individual roles is of great importance, especially during transport of short, thick sheets. Not only the greatest load-bearing capacity is required, but also a small distance between the effective lines of contact to prevent them from getting lost to avoid the metal sheets.

Nach einem weiteren Vorschlag sollen aus dem Ofen kommende Bleche unmittelbar von Magnetrollen, die als Elektromagnete ausgebildet sind, transportiert werden. Dabei sind zwischen den Rollen einzelne Platten angeordnet, die eine Durchbiegung des Bleches infolge der Magnetkräfte verhindern sollen. Abgesehen davon, daß Bleche nur bis zu einer bestimmten Temperatur magnetisierbar sind, ergeben die Platten zwischen den Rollen bei dünneren Blechen eine zweifellos unerwünschte Bremse beim Transport. According to another suggestion, sheets coming out of the furnace should be transported directly by magnetic rollers, which are designed as electromagnets will. In this case, individual plates are arranged between the rollers, which deflect should prevent the sheet metal as a result of the magnetic forces. Apart from that sheet metal The plates are only magnetizable up to a certain temperature an undoubtedly undesirable brake between the roles with thinner sheets Transport.

Alle diese Vorschläge berücksichtigen nicht das Vorkommen von kurzen Blechen, für deren Transport nur Rollen mit kleinem Durchmesser und geringem Rollenabstand in Frage kommen. Ebenso werden die Steifigkeit der Bleche und vor allem die unterschiedlichen Blechdicken nicht beachtet. Wenn Bleche von verschiedener Dicke transportiert werden, muß auch der Abstand zwischen Oberseite des Zufuhrrollgangs und der Unterseite der Magnetrollen verschieden sein. Schon bei der Übernahme der Bleche müssen diese genau in der durch die Unterseite der Magnetrdlen gebildeten Ebene anlaufen. Dies ist aber nur zu erreichen, wenn der Magnetrollgang in der Höhe verstellbar ist. None of these suggestions take into account the occurrence of short Sheets, for their transport only rolls with a small diameter and small roll spacing come into question. Likewise, the stiffness of the sheets and, above all, the different Sheet thicknesses not taken into account. If sheets of different thicknesses are transported, must also be the distance between the top of the infeed roller table and the bottom of the Magnetic rollers be different. When the sheets are taken over, they must be precise start in the plane formed by the underside of the magnetic spindle. This is but this can only be achieved if the height of the magnetic roller table is adjustable.

Die vorliegende Erfindung hat sichdie Aufgabe gestellt, eine Blechstapelanlage zu schaffen, welche die auf einem normalen Rollgang ankommenden Bleche von verschiedenen Längen, Breiten und Dicken mit gleichbleibender Geschwindigkeit übernimmt, weiterleitet und an bestimmten Stellen fallen läßt, um Stapel zu bilden. Erfindungsgemäß wird dies dadurch erreicht, daß die einzelnen Magnetrollen bei kleinem Durchmesser eine enge Rollenteilung haben und der Rollgangsrahmen mit den Elektromagnetrollen in seiner Höhenlage verstellbar ist. The present invention has set itself the task of a sheet stacking system to create which sheets of different sheets arriving on a normal roller table Adopts and forwards lengths, widths and thicknesses at a constant speed and drops at certain points to form stacks. According to the invention this is achieved in that the individual magnetic rollers have a small diameter have narrow roller division and the roller table frame with the electromagnetic rollers in its height is adjustable.

Ein Ausführungsbeispiiel der Erfindung ist in der Zeichnung schematisch dargestellt, und zwar zeigt Fig. 1 einen Längsschnitt durch den Magnetrollgang, Fig. 2 einen Schnitt nach Linie A-B der Fig. 1. An exemplary embodiment of the invention is shown schematically in the drawing shown, namely Fig. 1 shows a longitudinal section through the magnetic roller table, FIG. 2 shows a section along line A-B of FIG. 1.

Die auf einem normalen Rollgang 1 liegend ankommenden Bleche 2 werden bei gleichbleibender Ge- schwindigkeit unter ein in der Höhe verstellbares Gerüst 3 geleitet, wo sie von mit Elektromotoren 4 einzeln angetriebenen Rollen 5, die aus Elektromagneten bestehen, hängend weitergeleitet werden.
