Definitions
- the invention relates to a method for turning and final shaping of inflatable bodies made of fabric / n with or without coating, in particular air bags, using a corresponding device.
- the object of the present invention is therefore to provide an economical method for turning inflatable bodies, in particular air bags, by means of a device which is particularly suitable for this purpose.
- the turning process should also be carried out with the same device, the final shaping of the body or airbag.
- the fabric must not be stretched excessively. Furthermore, there must be no wrinkles.
- a stamp which is provided with a compressed air connection and a blow-out opening, the downward moving stamp pushing the body or airbag completely into the inverting tube while simultaneously turning the body or airbag;
- a sealing element which closes the upper edge of the sleeve tube pressure-tight after the stamp movement; such as
- the compressed air connection is in the upper part, especially directly at the beginning of the stamp.
- a slip head is arranged, which is provided with one or more blow-out opening (s), the compressed air connection being connected to the blow-out opening (s) of the slip head via an air duct contained in the punch. Furthermore, the everted head protrudes into the catching device in the closed state of the everting tube.
- the stamp has a sealing element, in particular a sealing plate made of metal and / or elastomeric material.
- the inverted tube is provided on its upper edge with a sliding, ball or roller ring, the shape, material and surface of which is designed in such a way that only minimal frictional forces are opposed to the inverting process.
- the inverted tube is formed in the transition area between the inverted tube end and catching device such that the molding process of the body or airbag is only opposed to a slight resistance.
- these device parts are firmly connected to a horizontally extending holding arm, each retaining arm in turn being in contact with a guide rail running parallel to the stamp and inverted tube, with vertical displaceability of the retaining arms.
- the holding arm is expediently arranged directly above the sealing element or the sealing plate; ie the sealing element or the sealing plate is an integrated part of the holding arm here.
- a catching device which limits the outlet of the body or airbag downwards by means of a horizontal bottom with the aim of making the end shape as flat as possible in the radial direction. It is also advantageous if, alternatively, the catching device is designed as a transport device for removing the turned and finally shaped body or airbag.
- FIG. 1a shows a sectional view of an airbag immediately after assembly
- FIG. 1 b shows a three-dimensional representation of an airbag according to FIG. 1 a;
- FIG. 2a shows a sectional illustration of an inverted and finally shaped airbag
- FIG. 2b shows a three-dimensional representation of an airbag according to FIG. 2a
- Fig. 4 shows a device in which the stamp in the Stülprohr with simultaneous
- FIG. 6 shows a device in the closed state of the everting tube while driving out the turned airbag while simultaneously striking the catching device
- Fig. 7 shows a device in the turned and final shape of the airbag.
- a airbag (immediately after assembly)
- the device comprises a guide rail 1, which is equipped with two horizontally extending holding arms 1 'and 1 ", which holding arms are vertically displaceable within the guide rail by means of a drive.
- the stamp 4 is provided with a sealing element 6 (here sealing plate).
- the stamp is now firmly connected to the holding arm 1 'directly above this sealing plate.
- a compressed air connection 5 while the end of the stamp 4 "is equipped with a slip head 8, which in turn is provided with one or more blow-out openings 5", the compressed air connection via an air duct 5' contained in the stamp with the or the outlet opening (s) of the everting head is connected.
- the inverted tube 2 itself is firmly connected to the holding arm 1 "approximately in its central region. At its upper edge 2 ', the inverted tube 2 is provided with a slide, ball or roller ring 7, the shape, material and surface of which is designed such that only minimal frictional forces are directed against it. Furthermore, the inverted tube is designed in the transition area 2 "between the inverted tube end and catching device 3 in such a way that the molding process of the airbag B (FIG. 6) is only one in the state C (FIG. 2a, 2b, 7) low resistance is opposed.
- the catching device itself is delimited downwards in the radial direction by means of a horizontal base 3 'for the purpose of making the airbag C as flat as possible (FIG. 7).
- the airbag A (FIG. 1 a, 1 b) placed with the opening above the inverting tube 2 is now pushed into the inverting tube 2 by the punch 4 that moves downward with the inverting head 8 (FIG. 4).
- the inverted tube moves downwards by means of a drive at half the speed of the punch (in the direction of the arrow according to FIG. 4). This makes it easier to pull the airbag into the inverted tube and prevents the formation of sharp folds. This is supported by the shape and material-optimized slide, ball or roller ring attached to the upper edge of the sleeve.
- the punch 4 moves relative to the inverted tube 2 until the entire airbag B is in the inverted tube in the already turned state.
- the sealing plate 6 seals the inverted tube upwards.
- the everting head 8 projects into the catching device 3. 6
- a strong air blast (via the compressed air connection 5) drives the airbag B out of the inverting tube through the air duct 5 'of the punch 4 and through the blowout opening 5 "of the everting head 8.
- the airbag strikes the horizontal floor 3 'of the catching device 3 then inflates and unfolds the airbag.
- FIG. 7 now shows the turned and finally shaped airbag C, which is then removed from the catching device 3.
- the punch 4 now moves at twice the speed of the inverting tube 2 (in the direction of the arrow), namely while opening the inverting tube (initial state according to FIG. 3).
