Definitions

  • the present invention relates to an apparatus and a process for treating sheet materials intended for covering motorcar dashboards provided with airbags, in particular invisible airbags.
  • portions intended for covering and concealing the airbag device are such shaped that they are provided with weakening regions or with regions where there is no material, along the separation lines, thereby promoting opening of the same in a controlled manner.
  • covering panels consist of an inner layer of foam material optionally reinforced with one or more rigid insert pieces, over which a thin layer of synthetic leather is applied.
  • Generally weakening of the panel structure is carried out by suitably scoring the foam material and/or weakening the rigid insert pieces therein contained.
  • scores can be made in the covering layer in order to prevent tearing thereof and avoid arising of anomalous deformations in the leather material and a non-instantaneous or uneven coming out of the airbag, as well as the possibility of spreading leather portions and the consequent impact of these portions on people within the driver and passenger compartment .
  • An apparatus has been recently accomplished for treating leather material intended for covering dashboards, in which the leather-cutting blade has two spacer elements integral therewith at the cutting end and more particulary two rollers intended for maintaining a predetermined insertion depth of the blade into h e leather material.
  • the leather sheet is laid down over a supporting surface and the blade penetrates through the covering layer until the rollers abut against the outer surface of the sheet material .
  • rollers substantially ensure a constant scoring depth.
  • a first drawback highlighted by this device is connected with the fact that too much pressure on the cutting tool causes a compressive strain in the leather material thereby increasing the cut depth and giving rise to leather tearing.
  • regions having a strong gradient of spatial variation as herein present hardly lend themselves to interposition of rubber materials for absorbing compressions of the cutting tool.
  • the tool pressure should not be directed perpendicularly to the surface to be cut, deformations and sliding actions created between the leather sheet and the support cause the score not to be very precise and the cut may pass through the whole leather layer.
  • the incapability of obtaining a high accuracy in scores is also due to the absence of appropriate fastening systems between the leather sheet and the locating surface.
  • the present invention aims at substantially solving all the above mentioned drawbacks.
  • An auxiliary object of the invention is then to avoid material removal (as it may happen with a V-shaped score or notch) by cutting the leather sheet in such a manner that the notch flaps are left close to each other, and the presence of recognizable marks on the visible surface of the dashboard is eliminated as much as possible.
  • - Fig. 1 is an elevation side view of a work head associated with an apparatus for treating sheet material in accordance with the present invention
  • - Fig. 2 is a diagrammatic plan view of an apparatus in accordance with the invention
  • FIG. 3 shows the supporting base of the apparatus referred to in Fig. 2;
  • FIG. 4 is a cross-section view of the cutting tool active on the sheet material shown in Fig. 3;
  • FIG. 5 shows an alternative embodiment of a work head active on the sheet material at two operating positions.
  • an apparatus for treating sheet materials intended for covering motorcar dashboards provided with airbags has been generally identified by reference numeral 1.
  • the apparatus is provided with a fixed bearing structure 2 over which one or more supporting bases 3 can be engaged for receiving a sheet material 4, to be submitted to working operations, on an operating surface 3a thereof defined on top.
  • the upper surface 3a of the supporting base 3 (see the representation in Fig. 3 in particular) has at least one locating portion of three-dimensional extension the shape of which substantially matches that of a corresponding surface of the dashboard to be covered with the sheet material 4.
  • this operating surface will substantially match that of the finished product, i.e. a dashboard to which the leather covering has already been applied and will be also made of materials adapted to give it the appropriate rigidity.
  • the locating portion 5 of three-dimensional extension will extend not only at the region where a score will be executed, but also at a surrounding region in order to enable a better positioning and engagement of the sheet material.
  • the sheet material too will be provided with a three- dimensional-extension conformation capable of facilitating its adaptation to, and positioning on the locating portion 5 with which it is to be engaged.
  • the shape of the leather sheet will match that of the motorcar portion to be covered with it.
  • base 3 has a first portion 7 substantially disposed at the region where the weakening line 8 is to be formed, which is made of a porous material, suitably-worked aluminium for example.
  • the porous-material portion 7 performs a dual function: it forms an as much as possible continuous (i.e. devoid of discontinuities due to holes or scores) support and, through appropriate sucking, enables locking of the portion to be submitted to working with a uniformly- distributed force.
  • the supporting base 3 then comprises a second portion 9 arranged peripherally of the first portion and having a predetermined number of through suction channels 10 suitably distributed over the whole surface and associated with a suction device "p" being part of the pneumatic locking means 6.
  • the pneumatic locking means 6 consists of said suction device "p" which is active on at least the first porous-material portion 7 and preferably on the second portion 9 too, by means of through suction channels 10.
  • mechanical locking means 11 may be provided as well, and it preferably consists of one or more bumpers of appropriate shape moved by respective actuators (not shown) and operating by a thrust action on the free side of the sheet material 4 to be treated.
  • bumpers 11 are preferably positioned at a portion immediately surrounding the region on which notching or scoring is to be executed.
  • Fig. 1 shows a work head 12 operatively active on the sheet material 4 to make at least one weakening line 8 of predetermined depth thereon.
  • the sheet material Since an invisible score is required to be made on the finished product, the sheet material has a resting side 4a (Fig. 4) bearing against the base 3 which corresponds to the visible leather side when covering of the dashboard has been carried out and a free side 4b (Fig. 4), in which the score is made and which is intended for being concealed when the leather sheet covers the dashboard.
  • the work head 12 is provided with means 13 for holding and moving a cutting tool 14, which means is arranged to move said tool along the predetermined weakening line 8.
  • the head work 12 comprises a control unit 30 active on the holding and movement means 13 to move tool 14 while keeping an active end 14a thereof to a preferably constant distance, preestablished for each point, from the locating portion.
  • the head work 12 also moves tool 13 in a path which, point by point, is a function of the geometry of the supporting surface.
  • control unit 30 will be able to be programmed and therefore will be provided with a memory block 31 carrying previously stored data or capable of, by an input interface 32, storing data 33 containing information relative to the geometry of the surface to be scored, the shape of the score to be carried out, and the score depth at the various points of the line.
  • the control unit 30 will also comprise a central processing unit 34 capable of reading the information and data from the memory block 31 and controlling, through appropriate actuators, the movements of the holding and movement means 13 for execution of the received instructions.
  • the holding and movement means 13 must enable the cutting tool 14 to carry out displacements in at least three main axes independent of each other, i.e. for example (this reference is not limited to the drawings) rotation about axes 15 and 16 and translation along axis 17, in order to achieve movement of the cutting tool 14 in a plane tangential and/or orthogonal to the locating surface.
  • the holding and movement means 13 also enables rotation (denoted by arrow 18 in Fig. i) of blade 14 around a fourth axis parallel to the blade 14 plane, preferably vertical and coincident with the translation axis 17, and possibly around a fifth rotation axis 19 parallel to the blade plane and preferably horizontal (see representation in Fig. 5).
  • a rotation about the vertical axis 17 is substantially required in that the cutting tool is provided with a flat blade that must always be displaced with its cutting profile along the direction tangent to the weakening line
  • the fifth horizontal rotation axis is needed because the inventive apparatus can be also used for making scores either on leather sheets for dashboards with which a layer of foam material has been previously associated or on leather sheets of high thickness. It is apparent that under this situation the thickness to be cut is greatly increased and, when surfaces of great three-dimensional conformation are concerned, it is necessary for the blade carrying out scoring to penetrate into the material in a direction orthogonal to the surface of the sheet material (see Fig. 5) .
  • the work head 12 (a "Yamaha” robot of the "scara” type, for example) may consist of a support block 20 from which a first arm 21 branches off which has a horizontal extension and is rotatably associated according to a vertical axis to the support block itself.
  • first end 22a of a second arm 22 which has a substantially horizontal extension too, is movable in rotation relative to the first arm and carries the cutting tool 14, at its opposite end 22b.
  • a motor electrically and/or pneumatically operated which is associated with the cutting tool 14 and is capable of making the tool carry out translations in the substantially vertical axis 17 to move the blade close to and away from the sheet material .
  • the work head further comprises a tool carrier associated with the head, from which the blade comes out and projects to a minimum degree in order to avoid bending problems during the cutting operations.
  • the apparatus is also provided with positioning-controi means 35 for the cutting tool and the supporting base.
  • the base 3 and cutting tool 14 positioning-controi means comprises at least one video camera having an optical reading axis inclined at 45° relative to the horizontal main axes of the work head.
  • Such an arrangement will enable positioning of the components to be verified relative to the vertical axis and both the horizontal axes.
  • the video camera also has the function of controlling both the real presence and the precise vertical arrangement of the blade axis.
  • the central processing unit (CPU) , after receiving data from the video camera, will be able to send appropriate signals to the user by audio or video alarm means 36 and cause immediate stopping of the work head 12 if the base or tool positions do not fall within the preestablished value gaps .
  • the CPU 34 will further carry out storage into the memory blocks 31, for each scoring and consequently for each leather sheet submitted to working, of the data detected by the video camera 35 and the executed cutting program.
  • the CPU 34 will be also able to carry out recording of data as regards the blade 14 position at predetermined intervals during the cutting cycle, by use of appropriate transducers 37 such as encoders to be associated with each of the movable axes of head 12.
  • the CPU 34 will also send a further signal to the alarm means, should the relative distance between the blade tip and the base be varied, due for example to wear of the blade itself, and will also automatically operate the new correct positioning of the blade.
  • the video camera carries out the control and verification operations as regards positions at least at the beginning of each cycle and at the end of each cycle on each leather sheet.
  • control means is to be positioned at an area as much as possible close to the cutting point so as to have a good optical access, while at the same time not interfering with the movements of the cutting head and with the mechanical locking bumpers.
  • a supporting base of three-dimensional extension is arranged, the shape of which substantially matches that of the dashboard surface to be covered with the leather material, and position thereof is verified by the video camera.
  • the work head cycle is started and it involves a first step in which protections around the apparatus are closed and the base and tool positions are controlled and possibly recorded.
  • a signal is sent from the central unit which is capable of stopping movement of the work head.
  • the CPU operates a relative repositioning of said components. In case of a correct position, the cutting operation is started.
  • the CPU may also record the work position of the blade, and the leather and supporting base positions during the leather-cutting step.
  • a blowing step carried out through the suction holes and the porous material may be also provided in order to remove the leather sheet from the base and clean the possibly closed suction holes.
  • the invention achieves important advantages.
  • the apparatus enables both the score typology to be varied (making U-shaped or H-shaped notches, for example) by modifying the parameter inputs contained in the memory block, and the concerned dashboard type to be varied by merely replacing the supporting base and resetting the control data of the trajectory which is a function of the geometry of the new supporting surface.
  • the invention is also advantageous in its secondary aspects .
  • Control on the positioning of the supporting base and tool enables the relative positioning between blade and leather sheet to be verified and possibly adjusted (which operation is necessary in case of wear of the materials) , and also stopping of the apparatus to be operated, if given positioning parameters were not respected. The whole is carried out with completely automated operations .
  • the same means also enables the production history of each leather sheet being treated to be recorded.

Abstract

L'invention concerne un appareil permettant de traiter des matériaux de maroquinerie destinés à être utilisés pour recouvrir des tableaux de bord d'automobiles pourvus d'air-bags invisibles, une base support (3) étant conçue pour recevoir, sur sa surface supérieure, ces matériaux de maroquinerie devant être soumis à un traitement. Ainsi, l'un des cotés desdits matériaux de maroquinerie repose sur cette base, ce coté correspondant au coté visible des matériaux de maroquinerie qui se présentent sous la forme d'une feuille tridimensionnelle (4) une fois le tableau de bord recouvert de cuir, l'autre coté étant destiné à être caché de la même façon que ledit tableau de bord est recouvert. Une tête d'usinage (12) portant un outil de coupe travaille ladite feuille (4) de manière à former sur celle-ci une ligne d'affaiblissement de profondeur prédéterminée. La surface de fonctionnement de ladite base support (3) présente une extension tridimensionnelle dont la forme correspond sensiblement à celle de la surface correspondante du tableau de bord destiné à être recouvert d'un matériau de maroquinerie. L'appareil de cette invention permet donc de pratiquer des entailles précises même sur des surfaces pourvues d'une forte extension tridimensionnelle.
