  • Fig. 3 a top view showing an upper level of the transport device 18 and the Fig. 4 shows a top view showing a lower level of the transport device 18.
  • the transport device 18 can in particular have a plurality of conveyor belt sections 36 and corner converters 38.
  • the conveyor belt routes 36 can transport individual workpiece carriers 14 between different stations or facilities of the device 10.
  • the printing processes take place within the printing device 12.
  • the respective workpiece carriers 14 must be positioned within the printing device 12, in particular on the printing table top 16 of the printing device 12.
  • the respective workpiece carrier 14 is positioned from the printing device 12 into a settling area 40 downstream in the material flow.
  • 16 settling areas 40 can be provided on both sides of the printing table top.
  • the workpiece carriers 14 can therefore be transported away from the printing table top 16 on both sides.
  • the workpiece carriers can be transported by a positioning device 20, which can also be formed by a conveyor belt section and forms part of the transport device 18.
  • a settling area 40 mentioned above can in particular also be designed as an inspection area and/or serve as an inspection area.
  • the respective workpiece carrier 14 is transported from the respective settling area 40 to the drying device 30.
  • the workpiece carrier 14 can be transported from the settling area 40a along the conveyor belt route 36a to the drying device 30.
  • the workpiece carriers are transported to the corner transfer device 38a, further along the conveyor belt route 36b to the corner transfer device 38b and then into the drying device 18.
  • the corner converter 38b can be transported further to the conveyor belt section 36a and then into the drying device 30.
  • the drying section 42 runs within the drying device 30.
  • the drying section 42 can be designed in two lanes, that is to say it can be formed by two conveyor belt sections 36c and 36d in order to increase the drying capacity. After passing through the drying section 42, the respective workpiece carrier 14 reaches a buffer storage 32 in which further drying or post-drying can take place.
  • the storage device 34 is arranged adjacent to the corner converter 38e. Starting from the corner converter 38e, the workpiece carriers are further transported along a return route which has the conveyor belt routes 36f and 36g.
  • the conveyor belt sections 36f and 36g can merge into one another along the conveying direction, whereby the downstream conveyor belt section 36g can have an inclination.
  • the conveyor belt route 36g be inclined downwards and thus a transfer of workpiece carriers from the in Fig. 3 shown upper level of the transport device 30 towards one in Fig. 4 shown lower level of the transport device 30 enable.
  • Both conveyor belt sections 36f and 36g of the return section can also have a vertical inclination.
  • the workpiece carriers 14 reach the in. through the conveyor belt section 36g Fig. 4 shown corner converter 38f. Starting from the corner converter 38f, the workpiece carriers 14 can be transported further either to the conveyor belt route 36h or to the conveyor belt route 36i.
  • the conveyor belt section 36h leads to the lift device 44a, through which the workpiece carriers 14 are lifted into the upper level of the transport device 18. Finally, raised workpiece carriers 14 can be transported further to the settling area 40b, from where the printing table plate 16 can be loaded by the positioning device 20.
  • the conveyor belt section 36i first leads to the corner converter 38g and from there further along the conveyor belt section 36j to the lift device 44b, through which the workpiece carriers 14 are lifted into the upper level of the transport device 18. Finally, raised workpiece carriers 14 can be transported further to the settling area 40a, from where the printing table plate 16 can be loaded by the positioning device 20.
  • the corner converter 38a can also be equipped with a lifting function for direct transport of the workpiece carriers 14 between the two levels of the transport device 18. This can be particularly advantageous if the printing device 12 is to be bridged over the shortest possible path, for example in order to carry out repeated drying without printing the workpiece carrier in the meantime. However, this can also be accomplished without a lifting function of the corner converter 18a, as can be seen from the arrangement of the conveyor belt sections 36.
  • the device 10 described above is particularly suitable for mass production of three-dimensional screen printing workpieces.
  • the device 10 enables extensive or complete automation of the screen printing process.
  • the risk of operating errors is reduced and the level of productivity can be significantly increased using a device 10 as described above.
