Definitions
- the invention relates to a device for Positioning on a means of transport in one mutual distance lying rectangular Sheet metal blanks.
- From DE-A1 43 00 729 is already a device for lateral orientation of moving forward in a stream Objects to a contact surface known.
- Such a device is sufficient not for aligning at high speed induced high-precision blanks for the production of containers.
- the Alignment accuracy can not be obtained and on the other hand would be oriented in the inclined position Sheet metal blanks when returning to the horizontal their lose the exact position again.
- the object of the present invention consists in to provide a device with the whole surface with a paint or an extruded plastic layer coated sheet metal blanks on a means of transport very can be positioned exactly in one subsequent processing along at least two opposite edges of the sheet metal blanks the paint, or the plastic layer from the sheet surface to remove.
- two parallel guided conveyor belts only partially and randomly aligned and positioned sheet metal blanks in the device in an exact parallel and spaced mutual location and with exactly in Longitudinally aligned edges to be machined adjusted and on the further transport route to the Processing station in the exactly positioned position held.
- reference numeral 1 is schematically indicated a roller-shear, in which from sheet metal a variety for the production of a hull for a sheet metal packaging certain, in predetermined size in terms of length and width tuned sheet metal blanks 3, also called blanks, are produced.
- the transport means 5 comprises in the example shown two parallel adjacent and at a distance encircling endless toothed belt 7, which rotate in pairs of axes 9 and 11 mounted guide rollers 13 and 15.
- the roller pair 15 is driven by a drive motor M shown only schematically.
- the mutual distance of the two conveyor belts 7 can be adjusted by axial displacement of the guide rollers 13,15 to the length L of the sheet metal blanks 3 to be positioned.
- the upper run 17 and the lower run 19 of the two toothed belts 7 extend parallel to one another.
- Below the upper two strands 17, means for holding the blanks 3 on the conveyor belts 7 in the form of magnets 21 are arranged in a first transport section A.
- rod-shaped magnet 23 are also arranged as holding means below the upper strands.
- In the middle second transport section B is missing holding means which hold the sheet metal blanks 3 immovably on the two transport means 7.
- the front run 25 of a continuous endless steel belt 27 is arranged laterally on one of the two toothed belts 7 and exactly parallel to its direction of movement P.
- the steel strip 27 passes around two support rollers 29 and 31 on vertical axes of rotation, of which one of the two, preferably the transport roller 31 is driven.
- the drive of the transport roller 31 is synchronized with the drive for the two toothed belts 7 and preferably done by the same drive motor M.
- a magnetic element 33 extends substantially over the entire gap between the magnets 21 and 23 below the Timing belt 7.
- a processing station 35 is schematically indicated as a rectangle and the sake of clarity to the right shifted.
- the coatings are removed in a very narrow, for example 0.5 to 2 mm wide, area along the two edges 37 of the sheet metal blanks 3 either on one side or on both sides.
- the removal of the varnish or plastic layer may be by laser beam or otherwise.
- the design and operation of the processing station 35 is not the subject of this invention and will therefore not be further explained.
- the magnets 21, 23 have a decreasing force of attraction on the sheet metal blanks 3 at the ends projecting towards the center of the transport device.
- the decreasing attraction can be generated in different ways.
- the ends of the magnets 21,23 are tapered or the magnets 21,23 are inclined in this area to the toothed belt 7, so that their distance increases and thus their attraction to the sheet metal blanks 3 decreases.
- the magnet 23 can via the Transport sections A and C synchronously circulating Conveyor belts 41,43 (in broken lines in Figure 2 indicated), whose underlying dreams 45,47 press the sheet metal blanks 3 on the toothed belt 7 and protect against slipping.
Description
- Figur 1
- ein Grundriss der Vorrichtung,
- Figur 2
- eine Seitenansicht der Vorrichtung und
- Figur 3
- einen Schnitt durch die Vorrichtung längs Linie III-III in Figur 1.
In einer weiteren Ausführungsform (keine Abbildung) tritt an die Stelle des vorderen Trums 25 eines Stahlbandes eine geradlinig verlaufende Richtfläche, hinter der die Magnetelemente 33 angeordnet sind.
Am ausgangsseitigen Ende der beiden Zahnriemen 7, in den Figuren 1 und 2 auf der rechten Seite, ist schematisch als Rechteck und der besseren Übersichtlichkeit halber nach rechts verschoben eine Bearbeitungsstation 35 angedeutet. In dieser Bearbeitungsstation 35 werden entlang der beiden Kanten 37 der Blechzuschnitte 3 entweder einseitig oder beidseitig die Beschichtungen in einem sehr schmalen, beispielsweise 0,5 bis 2 mm breiten Bereich entfernt. Das Entfernen des Lacks oder der Kunststoffschicht kann durch Laserstrahlen oder auf andere Weise erfolgen. Die Ausbildung und Funktionsweise der Bearbeitungsstation 35 ist nicht Gegenstand dieser Erfindung und wird daher nicht weiter erläutert.
Die Magnete 21,23 weisen an den gegen die Mitte der Transportvorrichtung ragenden Enden eine abnehmende Anziehungskraft auf die Blechzuschnitte 3 auf. Die abnehmende Anziehungskraft kann auf unterschiedliche Weise erzeugt werden. Beispielsweise sind die Enden der Magnete 21,23 verjüngt oder die Magnete 21,23 liegen in diesem Bereich geneigt zum Zahnriemen 7, so dass deren Abstand zunimmt und damit deren Anziehungskraft auf die Blechzuschnitte 3 abnimmt.
Bei niedriger Transportgeschwindigkeit kann auf die Magnete 21 im Bereich A verzichtet werden.
