Definitions

  • the invention relates to a gripping device for carrying a sticky material web, with a carriage movably guided in its longitudinal direction and a remotely operated holding pliers arranged thereon, the pliers legs of which are designed to reduce adhesion on their mutually facing inner side.
  • Mat strips with different widths can be produced either by carrying out only one cross-cutting process (with the width of the material web unchanged) or by dividing them lengthways and in the transverse direction (i.e. by forming mat strips whose width is less than the width of the material web) he follows. With a view to better economy and less susceptibility to faults, the production of the mat strips should be done in this way run that the material web is first freed of its cover films before their subdivision in the transverse direction or in the longitudinal and transverse directions.
  • the further transport of the then sticky material web into the area of the cutting devices and the subsequent placement of the mat strip (s) on a transport device requires the use of at least one gripping device, by means of which the end section of the sticky material web is gripped, carried along and after carrying out the cutting process or the cutting processes is released.
  • a gripping device for carrying a textile web of the type mentioned above is known, but the inside of the pliers legs is not designed to reduce adhesion.
  • a holding pliers is known, the pliers legs of which have an anti-adhesive surface on their mutually facing inner side.
  • the invention is therefore based on the object to provide a gripping device with which tensile forces can be exerted on sticky material webs and which, with a long service life and low maintenance, makes it possible to deposit the mat strips produced by lower parts without problems and with sufficient accuracy.
  • the object is achieved by a gripping device with the features of claim 1.
  • the basic idea of the invention is then to equip the holding pliers forming part of the gripping device on their pliers legs with an adhesion-reducing film that runs through their area and to arrange and drive them in such a way that when the holding pliers are switched off without power, the mat strip initially located between the pliers legs does not become one Performs movement - towards the forehead sections of the Pliers leg is pulled off and detaches from the sticky mat strip.
  • the subject of the invention preferably has a support frame fastened to a carriage, which is movably held in relation to the slide in the longitudinal direction of the material web and which has a deflection point which supports the adhesion-reducing film.
  • the adhesion-reducing film is fastened on both sides via its end sections, which are located one behind the other in the transport direction of the material web, to a tenter frame which is likewise arranged so as to be displaceable in the longitudinal direction of the material web with respect to the support frame.
  • the adhesion-reducing film executes a movement along the mutually facing inner sides of the pliers legs in the direction of their end sections if the slide is displaced counter to the transport direction of the material web.
  • the required pre-tensioning of the anti-adhesive film is generated by a pre-tensioned spring element which acts on the tensioning frame with a pre-tensioning force which is effective in the direction of transport of the material web and which engages supported on the support frame at the same time.
  • the holding pliers are equipped with a pliers leg pivotably arranged on the carriage in such a way that the pliers legs assume a detaching position which is at least approximate to their closed position when the pliers drive is switched off.
  • the movable arrangement of the tensioning frame with respect to the support frame can be realized in a simple manner in that the latter is equipped with support rollers, between which the tensioning frame is held perpendicularly and transversely to the longitudinal extent of the material web (that is to say only movable back and forth in the longitudinal direction of the material web).
  • Claim 2 The mobility of the carriage with respect to the support frame and the tensioning frame is ensured by guide rollers which are movably supported on the tensioning frame in the longitudinal direction thereof (claim 3).
  • the holding pliers are preferably designed in such a way that the pliers limb, which is at the top with respect to the material web, is pivotably connected to the carriage (claim 4).
  • the adhesion-reducing film is fastened to the tenter frame in such a way that it wraps around the exposed end portions of the pliers legs (ie facing the material web) (claim 5).
  • the attachment point for the film end section of the upper pliers leg lies - seen in the direction of the transport movement of the material web - in front of the attachment point of the other film end section (claim 6).
  • the end sections of the pliers legs have suitable recesses on their inside (claim 7).
  • the recesses can in particular be realized in that the inner sides of the pliers legs are provided with an inclined inner wall section following the end sections.
  • the subject of the invention is preferably designed in such a way that the spring element acting on the clamping frame, the detaching drive acting on the slide and the pliers drive acting on a pliers leg are designed as cylinder units (claim 8).
  • the spring element in particular can consist of a mechanical spring with an adjustable preload force.
  • the support frame is connected to the carriage in such a way that it can be swung out about a horizontal axis and can be locked in a working position which can be changed via an adjustment stop (claim 9).
  • the carriage is preferably equipped with a brake, by means of which the support frame can be held in a pivoting position outside of its working position (claim 10); the brake ensures that the support frame does not perform any unwanted movement outside of its working position without the application of force.
  • an SMC resin mat web 2 is unwound from a coil 1 past a deflection roller 3 in the direction of the arrow 4 and fed via a feed device 5 with feed rollers 5a, 5b to a cross-cutting device 6, by means of which the sticky resin mat web is transversely directed can be divided.
  • the feed device 5 there is one between the feed device 5 and the cross-cutting device 6 Clamping device 7 with height-adjustable clamping jaws 7a, 7b and, on the other hand, a cover film take-off with take-off rollers 8a, 8b.
  • the cover film is used to pull the upper and lower cover films 9a and 9b arranged on the resin mat web 2 up and down, the clamping jaws opened during the transport movement of the resin mat web 2 simultaneously serving as a scraper knife.
  • the transport movement of the resin mat web 2 (to the right in FIG. 1) is interrupted; the clamping device 7 then assumes the closed position in which the clamping jaws 7a, 7b hold the resin mat web 2 and also the cover foils 9a, 9b.
  • the cross-cutting device 6 with the transverse knife 6a is - seen in the direction of transport (arrow 4 in FIG. 1) of the resin mat web 2 - a longitudinal cutting device 10; this has one or more knives 10a, corresponding to the desired number of mat strips to be produced.
  • Each knife is held rotatably about a fixed axis 10b arranged below the plane of the material web on a swivel arm 10c, which can be moved back and forth by means of a swivel drive in the form of a cylinder unit 10d.
  • the longitudinal cutting device 10 is designed in such a way that each knife 10a by swiveling from below into the area of the resin mat web 2 has a cutting movement opposite to its transport movement Longitudinal direction of the Harzmattenbahn can run.
  • the cutting movement is caused by moving the swivel arm 10c counterclockwise.
  • a gripping device 11 is provided, which can be moved via a carriage 12 perpendicular to the plane of the drawing on two stationary guide rails 13 so far in the direction of the clamping device 7 that their holding pliers 14, which are arranged next to one another at a distance, engage the jaws 7a, 7b grasp end portion 2a of the resin mat web 2 projecting to the right, hold it there and carry it in the transport direction (arrow 4).
  • This end section extends - corresponding to the position of the cross-cutting device 6 - to the effective area of the transverse knife 6a.
  • the resin mat web 2 is carried to the right by moving the carriage 12, while at the same time removing its cover foils 9a, 9b.
  • the longitudinal cutting device 10 is put into operation by extending the cylinder assembly 10d, with the result that each knife 10a performs a cutting movement past the moving holding tongs 14 and thereby divides the resin mat web carried by the holding tongs in the longitudinal direction into several mat strips.
  • the movement of the Resin mat web 2 interrupted by stopping the carriage 12 and the feed device 5 and by actuating the cross-cutting device 6 the resin mat web 2 is divided transversely to its longitudinal extent, the already projecting, freely projecting end section 2a also being formed.
  • the carriage 12 with the holding tongs 14 continues its entraining movement into the region of a transport device, not shown, on which the mat strips produced - possibly also with the formation of mat stacks - are deposited.
  • the transport device By means of the transport device, the mat strips or the mat stacks formed therefrom can be fed to a pressing tool for further processing.
  • a support frame 16 is attached to the carriage 12 (shown without guide rails) via a swivel bearing 15 with a horizontal axis of rotation 15a, which has four laterally projecting support rollers 16a in its central section and a support roller 16b at its end section facing away from the swivel bearing 15 and - in the transport direction of the resin mat web ( Arrow 4 seen in Fig. 1) - lying behind this carries a deflection roller 16c.
  • a tensioning frame 17 is slidably held between the support rollers 16a, the angled front or Rear section 17a and 17b is each equipped with a clamping unit 18 and 19, respectively.
  • the tensioning frame 17 serves at the same time as a guide track for a slide 20 equipped with four guide rollers 20a, the downward extension 20b of which carries the already mentioned holding tongs 14 via the pliers legs 14b located below.
  • the tensioning frame 17 and the slide 20 with the holding tongs 14 are thus held directly or indirectly on the support frame 16 in such a way that they can perform a longitudinal movement in the direction independent of the support frame, which is caused by the support rollers 16a or by the tensioning frame 17 and the guide rollers 20a is predetermined.
  • the support frame 16 has a stop surface 16d, via which it can be held in its working position by means of a locking device 21.
  • the locking device consists of a bracket 21a immovably connected to the carriage 12, in which a retaining bolt 21b is guided to be displaceable in the longitudinal direction and can be locked by means of an articulated lever 21c.
  • the length of the retaining bolt 21b can be changed via an adjusting nut 21d; this change in length simultaneously affects the position of the support frame 16, for example with respect to a vertical plane.
  • the carriage 12 On its underside facing the tensioning frame 17, the carriage 12 is additionally equipped with an adjusting screw 12b serving as a counter-stop, on which the support frame 16 supported immovably in both directions of rotation under the action of the retaining bolt 21b via a second stop surface 16e above the support rollers 16a.
  • the holding pliers 14 are composed of an upper pliers arm 14a and the lower pliers arm 14b already mentioned, the rear section of which extends beyond the upper pliers arm and is immovable is connected to the extension 20b of the carriage 20.
  • the upper pliers leg can be pivoted about an axis 14c which is held on the lower pliers leg and forms an articulation point and merges into an adjusting arm 14d in the region thereof.
  • the pliers drive which causes the movement of the upper pliers limb 14a consists of a cylinder unit 22 which is connected in an articulated manner to the adjusting arm 14d or to the extension 20b of the slide 20 via its piston rod 22a and its cylinder housing 22b. By extending the piston rod 22a, the holding tongs 14 can be brought into the closed position shown.
  • their pliers legs are provided on their mutually facing inner side 14e or 14f with a continuous adhesion-reducing film 23 which has an adhesion-reducing plastic coating.
  • the adhesive-reducing film 23 is supported one after the other on a deflecting surface 17d of the front section 17a, on the end section 14g of the upper pliers arm and on the support roller 16b of the support frame 16, is deflected under the action of the deflecting roller 16c into the region of the inside of the lower pliers arm 14b, is supported on its end section 14h and extends below the last-mentioned pliers leg, bearing against a deflection surface 17e of the rear section 17b, into the region of its second fastening point 17f, at which it is held between the clamping piece 19a of the clamping unit 19 and a counter surface of the rear section
  • the adhesion-reducing film 23 is thus arranged in such a way that the fastening point 17c for the film end section 23a of the upper pliers leg 14a - seen in the direction of transport of the material web - lies in front of the fastening point 17f of the other film end section 23b (on the rear section 17b of the tenter frame 17).
  • the deflection roller 16c forms a deflection point which - since the deflection roller is a component connected to the support frame 16 - is stationary both with respect to the tensioning frame 17 and with respect to the slide 20.
  • the adhesion-reducing film 2 can be tensioned under the action of the deflection roller 16c.
  • a spring element in the form of a Cylinder unit 24 causes articulated between a bracket 16f on the central region of the support frame 16 and on a projection 17g of the tensioning frame 17; the cylinder assembly 24 in question is continuously pressurized in the operating state of the gripping device in such a way that it acts in the manner of a compression spring on the projection 17g on the clamping frame 17, which is guided in the longitudinal direction; the pretensioning force is absorbed by the adhesion-reducing film 23 clamped on both sides.
  • a detaching drive in the form of a cylinder unit 25 is also attached to the console 16f, the piston rod 25a of which is articulated to a projection 20c of the slide 20 above the guide rollers 20a.
  • the cylinder units 24 and 25 are supported at a small distance next to each other on the console 16f (cf. FIG. 3); the cylinder unit 25 has a larger effective diameter than the cylinder unit 24 equipped with a longer stroke length.
  • the holding pliers 14 - with the cylinder assembly 22 depressurized and the deflection roller 16c and the guide roller 16b held stationary - are also moved to the right, with the result that the adhesion-reducing film 23 on the inside between the two pliers legs 14a, 14b executes an opposite movement at the same speed and thereby from the end section 2a of the resin mat web, which is initially located between the pliers legs:
  • the film sections lying against the resin mat web are pulled over the end sections 14g and 14h of the pliers legs, whereby the end section of the sticky resin mat web is released without any own movement.
  • the pliers legs are each provided with a recess 14i and 14k on the inside, following the end sections 14g, 14h, the depth of which increases over a predetermined length in the direction of the pliers rotation axis 14c.
  • the pivot bearing 15 (cf. FIG. 3) is equipped with a brake in the form of a preloaded plate spring 15b. This presses the support arm 16 against the connection surface 12a of the carriage 12 in such a way that the support frame pivoted out of the working position in the counterclockwise direction maintains a swivel position once it has been used without any additional external force.
  • the pivoting process is made possible in that the retaining bolt 21b is returned in the direction of the bracket 21a by lifting the articulated lever 21c.
  • the gripping device 11 described above works as follows: To grasp the end section 2a of the resin mat web projecting to the right via the clamping device 7, the carriage 12 is moved to the left against the transport direction with the holding pliers 14 open until the lower pliers leg 14b lies below at least part of the end section. The holding pliers are then closed by lowering the upper pliers limb 14a, the cylinder assembly 22 remaining pressurized. By moving the carriage 12 to the right, the resin mat web is moved accordingly over the fixed end section 2a. After the necessary cutting operations have been carried out (dividing the resin mat web in the transverse direction or in the transverse and longitudinal directions), the carriage 12 is moved into a predetermined storage position with the holding pliers 14 still closed.
  • the cylinder assembly 22 is now switched off so that the upper pliers limb 14a is essentially only weight-bearing against the end section 2a.
  • the slide 20 is moved to the right by extending the cylinder assembly 25 with the holding pliers 14, the adhesion-reducing film 23 carrying out the opposite movement already described in the direction of the end section 14g, 14h of the associated pliers limb 14a or 14b detaches from the stationary section 2a.
  • the advantage achieved by the invention is that it provides a guarantee that the sticky resin mat web can be detached properly and thus stored in a targeted manner by a suitable detachment movement of the adhesion-reducing film in the area of the holding pliers.
  • the adhesion-reducing film in the area of the pliers legs can also be attached differently than described and shown. It is essential in the sense of the proposed solution according to the invention that the adhesion-reducing film executes a peeling movement during the detaching process, by means of which the sticky resin mat web is automatically conveyed out of the area of the pliers legs without the need for a transverse force on its surfaces.
  • the gripping device can be equipped with a plurality of supporting frames, clamping frames, slides and holding tongs, etc., which - held on a common carriage - lie at a distance from one another transversely to the longitudinal extent of the material web to be processed. If, for example, a material web is to be divided into two mat strips, a gripping device with two holding tongs is used.
