Definitions
- the invention relates to methods for draping flat semi-finished products according to the preamble of claim 1, a molded part according to the preamble of claim 8, a
- Draping flat semi-finished products plays an important role in the production of molded parts, for example in the automotive sector.
- Contacting section includes, the stiffness is selectively adjustable between a dimensionally stable state and a flexibly mouldable state and which is able to generate a suppressive force as a gripping force.
- the gripper can be used, for example, to press an object into a shape or to take a negative shape of the shape and to suck in a limp object so that it adheres to the negative shape.
- Workpiece can be picked up and shaped on an external shaping tool.
- the invention is based on the object of creating a new method for draping flat semifinished products which is significantly more flexible than the known solutions.
- the object is solved by the subject matter of independent claims 1, 8, 9 and 10. Further preferred embodiments of the invention result from the other features mentioned in the subclaims.
- a first aspect of the invention relates to a method for draping flat semi-finished products, in which a gripper is used, which comprises a contacting section, the
- Dimensional rigidity is selectively adjustable between a dimensionally stable state and a flexibly mouldable state and which can generate a suppression as a gripping force.
- This can be a gripper, for example, as is known from DE 10 2012 003 094 A1.
- the method comprises the following steps:
- the blanks can represent, for example, side or top surfaces of the draping shape and have protrusions in the area of edges, corners or joints, for example.
- the flat semi-finished products can be, for example, semi-finished products
- the stiffness can be characterized, for example, by an elastic modulus in the range from 5000 N / mm 2 to 70000 N / mm 2 . Likewise, the stiffness can be characterized by a small size of the blanks, which can cover a range from 100 mm 2 to 1200 mm 2 , for example in the flat state.
- a machine table comprising a portal robot, which in turn comprises the gripper, is used and that different cuts are provided on the machine table, which correspond to different draping shapes and that alternate or, in parallel, the blanks are placed on the corresponding draping forms using the gripper.
- the machine table comprises at least two portal robots and that a first portal robot places blanks for a first draping shape at a transfer position on the machine table, these are picked up by a second portal robotic and placed on the first draping shape and that the first gantry robot is placed during a cut for a second draping mold, which is then picked up by the second gantry robot and placed on the second draping mold.
- the embodiments can, for example, be 3D printed and correspond to the molded part to be produced.
- an embodiment of the draping shape is used and the gripper contacts the embodiment in a flexibly moldable state and then changes to the dimensionally stable state and thus molds a negative image of the embodiment and that the blanks are then made by contacting the blanks are placed on the negative image with the gripper.
- the machine table comprises a shape-flexible section
- the blanks are provided on the shape-flexible section and are contacted with the negative image embodied by the gripper.
- the form-flexible section can comprise, for example, an elastomer cushion or also an area fed by active media, for example liquid or gaseous active media. This will place the blanks on the gripper, which itself
- the flexible section can also be segmented to make it easier to place different blanks.
- the gripper can be pivoted on.
- Another aspect of the invention relates to a molded part, produced or producible in a method according to the preceding description.
- Another aspect of the invention relates to a manufacturing device designed for
- Another aspect of the invention relates to a vehicle comprising a molded part according to the invention as described above.
- the invention relates to a method in which molded parts can be produced. It is provided that blanks of flat semifinished products are deposited on partial areas of an embodiment of the molded part.
- Figure 2 blanks of semi-finished products, as they can be used in a method according to the invention
- FIG. 3 shows a negative image of a draping shape formed by a gripper in relation to different variants of draping shapes
- Figure 4 shows an inventive vehicle.
- FIG. 1 shows an example of a sequence of a method according to the invention using a manufacturing device 10 according to the invention.
- the manufacturing device 10 comprises a machine table 12 with two portal robots 14, 16.
- the portal robots 14, 16 can be moved in the longitudinal direction L, transverse direction Q of the machine table 12 and in the vertical direction V to the machine table 12.
- the portal robots 14, 16 are of identical design, so that, for simplification, the further details are described using a second portal robot 16 as an example.
- the second portal robot 16 is equipped with a gripper 18.
- the gripper 18 comprises a contacting section 20 which is designed as a granule cushion.
- the stiffness of the granule cushion can be selectively adjusted between a dimensionally stable state and a flexibly mouldable state according to the prior art. According to the prior art, a suppression as a gripping force can also be generated via the granulate cushion.
- blanks 22, 24 are provided on the machine table 12. The blanks 22, 24 are cut flat
- Embodiments 26, 28 of draping molds 30, 32 are provided on the machine table 12 in the area of the second portal robot 16.
- the blanks 22 correspond to a first draping mold 30 and the blanks 24 correspond to a second draping mold 32, more precisely each with partial regions 34 of the draping molds 30, 32 (more details in FIG. 2).
- the blanks 22 are then deposited on the corresponding subregions 34 of the first draping mold 30.
- the blanks 24 are placed on the
- the second draping shape 32 includes, by way of example only, a side face 36, a top face 38 and a groove 40 in the top face 38, the partial areas 34 of the FIG form second draping mold 32.
- the blanks 24 comprise blanks corresponding to the partial areas 34.
- the blanks 24 are placed on the corresponding subregions 34 of the second draping mold 32.
- the blanks 24 preferably have protrusions 42, in particular in the region of corners 44 and the like.
- the first gantry robot 14 thus places blanks 22 for the first draping mold 30 at a transfer position 46 on the machine table 12. There, the blanks 22 are successively picked up by the second gantry robot 16 and placed on the first draping mold 30. During this time, the first portal robot 14 already places blanks 24 for the second draping form 32 at a transfer position 46 '.
- the molded part 48 is attached to one by the second portal robot 16
- Removal position 50 placed which is indicated by the portal robot shown in dashed lines.
- the second gantry robot 16 can then pick up the blanks 24 at the transfer position 46 ′ and place them on the second draping mold 32.
- the second gantry robot 16 comprises several grippers 18, for example, also in parallel, blanks 22, 24 can be placed on the corresponding drapery forms 30, 32 via the gripper 18.
- the gripper 18 contacts the embodiment 52 with its contacting section 20, which is in a flexibly mouldable state. Once the contact has been made, the contacting section 20 changes into a dimensionally stable state. This creates a negative image 56 of the embodiment 52 in the contacting section 20. The right part of FIG. 2 shows that this can easily be done with an embodiment 58 of another draping shape 60, the same gripper 18 being usable.
- the sectional view schematically shows that the gripper 18 contacts the blank 24 in the contacting section 20 with the molded negative image 56 and thus deposits the blank 24 on the negative mold 56.
- the machine table 12 in this variant comprises a section 62 that is flexible in shape.
- the blank 24, as shown in the figure on which the sectional view is based, is provided on the section 62 that is flexible in shape.
- the flexible section 62 can also be segmented, so that a plurality of blanks 24 can be provided on segments at the same time.
- FIG. 4 shows a vehicle 64 according to the invention, in the present case a motor vehicle 66.
- the motor vehicle 66 comprises one or more molded parts 48, produced in the method described above.
- An interior part 68 can be an example of this.
