Definitions

  • the invention relates to a device for Positioning on a means of transport in one mutually spaced rectangular Sheet metal cuts.
  • the object of the present invention is now to to create a device with the whole a lacquer 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 remove.
  • the on a means of transport e.g. two in parallel guided conveyor belts only partially and randomly aligned and positioned sheet metal blanks in the device in an exact parallel and spaced mutual position and with exactly in Longitudinally aligned edges to be machined adjusted and on the further transport route into the Processing station in the exactly positioned position held.
  • reference numerals 1 schematically indicate a sheet-metal shear in which a plurality of sheet-metal blanks 3, also known as blanks, are used, which are intended for the production of a hull for a sheet-metal container and are of a predetermined size and length and width.
  • the sheet metal blanks 3 are individually transferred to a means of transport 5 from the scissors 1.
  • the transport means 5 comprises two endless toothed belts 7 lying parallel to one another and rotating at a distance, which run in pairs of guide rollers 13 and 15 mounted on axles 9 and 11.
  • the pair of rollers 15 is preferably driven by a drive motor M, which is only shown schematically.
  • the mutual distance between the two conveyor belts 7 can be adjusted to the length L of the sheet metal blanks 3 to be positioned by axially displacing the guide rollers 13, 15.
  • the upper run 17 and the lower run 19 of the two toothed belts 7 run 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 magnets 23 are also arranged as holding means below the upper runs 17.
  • In the middle second transport section B there are no holding means which hold the sheet metal blanks 3 immovably on the two transport means 7.
  • one of the two toothed belts 7 is arranged laterally and exactly parallel to its direction of movement P, the front run 25 of a continuous steel belt 27.
  • the steel belt 27 runs around two support rollers 29 and 31 on vertical axes of rotation, one of which, preferably the transport roller 31, is driven.
  • the drive of the transport roller 31 takes place synchronously to the drive for the two toothed belts 7 and is preferably done by the same drive motor M.
  • a magnetic element 33 extends essentially over the entire space between the magnets 21 and 23 under the Timing belt 7.
  • a rectilinear straightening surface behind which the magnetic elements 33 are arranged, takes the place of the front run 25 of a steel strip.
  • a processing station 35 is indicated schematically as a rectangle and for the sake of clarity, shifted to the right.
  • the coatings are removed along the two edges 37 of the sheet metal blanks 3 either on one side or on both sides in a very narrow, for example 0.5 to 2 mm wide area.
  • the lacquer or the plastic layer can be removed by laser beams or in another way.
  • the design and mode of operation of the processing station 35 is not the subject of this invention and is therefore not further explained.
  • the magnets 21, 23 have a decreasing attractive force on the sheet metal blanks 3 at the ends projecting towards the center of the transport device.
  • the decreasing attraction can be created 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 their attraction force on the sheet metal blanks 3 decreases.
  • the Transport sections A and C rotating synchronously Conveyor belts 41, 43 may be arranged, the dreams below 45,47 press the sheet metal blanks 3 onto the toothed belt 7 and protect against slipping.
  • the mode of operation of the device is explained in more detail below.
  • the sheet metal blanks 3 cut in the conventional manner on the scissors 1 are loosely placed on the two toothed belts 7 running in parallel or fall onto them and are transported in the randomly assumed position in the direction of the arrows P.
  • the sheet metal blanks 3 reach the first transport area A, in which the magnets 21 are arranged under the upper runs 17, they are held in a frictional manner and can consequently also be transported at high speed, for example 20 to 100 m per minute, without the risk there is that they stand out due to their light weight by buoyancy from the toothed belt 7 serving as a means of transport 5.
  • the sheet metal blanks 3 which are still not aligned, that is to say neither parallel to one another nor exactly positioned with respect to the edges 37, are freed from the holding force of the magnets 21 as soon as they reach the transport section B. They are now loose and therefore easily laterally displaceable on the two runs 17 of the toothed belt 7. From the magnetic element 33, which is located behind the front run 25 of the circumferential band 27 made of non-magnetic steel, they are pulled onto the steel band 27 until the in Figure 1 lying on top edge 37 fits snugly on the steel strip 27.
  • the steel belt 27, or its front run 25, runs exactly parallel to the transport direction P of the two toothed belts 7.
  • the sheet metal blanks 3 After the sheet metal blanks 3 have been exactly aligned in the transport section B and are held in the new position during the alignment, they arrive in the third transport section C. and are attracted to the toothed belts 7 by the magnets 23 lying below the upper runs 17 and conveyed into the processing station 35 in the exactly positioned immovable position and processed there.
  • the processing ie the removal of strip-like sections of the lacquer or coating close to the edges can thus be carried out extremely precisely and with a minimal width, which is required for welding. If the transport speed is low, the magnets 21 in region A can be dispensed with.
