Definitions

  • This invention concerns a holding and advancing device for cork slabs of irregular shapes, sizes and edges, intended to supply the said slabs to a treating apparatus.
  • the device of this invention is applicable, for example, to various natural cork slab treating apparatus that are employed in the manufacture of natural cork plugs and discs.
  • the utility model document ES-A-1052712 makes known a perfected multiple circular saw that includes a support structure for a cutting disc or blade, together with a drive system for the slabs to be cut with the blade during the advance of such slabs in a horizontal plane.
  • the drive system consists of two lower driven roller groups: one is located at the entrance, before the cutting position, and the other at the exit, after the cutting position, together with the corresponding upper pressure idler rollers that make contact with the upper faces of the slabs, the lower faces of which are on the lower driven rollers.
  • the ends of the pressure rollers are supported on freely rotating levers and the pressure of the said rollers on the slabs is adjustable by means of pneumatic cylinders connected by their shafts to these levers.
  • Both the driven support rollers and the pressure rollers can have a toothed surface in order to ensure drive.
  • the slabs are held to the cutting disc or blade by means of sliding shoes that are independent of the drive system.
  • a drive system of driven rollers as described in the cited document has the inconvenience of not being applicable when the slabs to be handled have irregular shapes, sizes and edges, such as, for example, in the cork stopper industry, where the natural cork slabs that are employed possess significant irregularities with respect to thickness, even in different areas of the same slab.
  • the driven roller drive system as described in the cited document does not anticipate an intermittent forward movement since the cut is made in a direction that is parallel to the advance.
  • machines are known in which the slabs are manually advanced on a support surface in direction of a treating apparatus, until contact is made with stops that are located at a desired distance in accordance with the treatment to be carried out.
  • a vertically moving pressure bar in a position close to the treating apparatus that is driven to press the slab against the support surface in order to immobilise it during the treating operation.
  • One example of such as unit includes a slicing machine in which a motor-driven carriage moves a cutting disc or knife in a transversal direction and in interference with the slab until it cut makes a slicing cut.
  • the pressure bar is mounted on moving supports that can accept a certain inclination in relation to the support surface in order to adapt to the variations in slab thickness and rise to completely free the slab and then descend again to fix it in place in accordance with the intermittent forward movements made by the operator.
  • These ascending and descending movements of the pressure bar are usually produced by a pedal worked by the operator and which usually involve a significant loss of time.
  • cork stopper industry also knows machine for die-stamping the stoppers from previously cut slices and also machines that cut circles from a thin slab of cork agglomerate, in which the material is moved forward using driven rollers.
  • cork-slice thickness although not possessing the precision of other slabs of material, is significantly more regular than natural cork slabs.
  • EP-A-1010506 discloses a method and apparatus for the manufacture of a band or ribbon from bark, the apparatus comprising means for driving a band or a ribbon in its longitudinal direction towards a cutting tool providing the features included in the preamble of claim 1.
  • One objective of this invention is to contribute to the overcoming of the previous and other inconveniences by means of a slab holding and advancing device that is applicable to natural cork slabs and carried out at least the holding operation and optionally the advance movement by means of at least one position pressure roller that adjusts itself to the slab thickness variations and is optionally motor driven.
  • This invention contributes to achieving the previous and other objectives by providing a machine that holds and advances the slabs and comprising at least one pressure roller arranged to rotate with respect to a shaft mounted to rotate in relation to a support surface in a guided, positionable fashion ; some means to move the roller designed to move the said roller closer to or further away from the said support surface with the interposition of at least one of the slabs in order to make contact with the slab or to free it; some means of forward movement designed to advance the slab over the support surface under the action of the pressure roller to a treating apparatus locate operationally in relation to the support surface; and some means of pressure designed to apply a determined pressure by means of the pressure roller, with this determined pressure being selected in function of whether the said slab is being advanced or being treated by the said treating apparatus.
  • Said means of roller movement are designed to independently move each end of the pressure roller to allow a pressure roller inclination variation with respect to the support surface in order to adapt to any possible thickness variations of the said slab, and the said means of pressure are capable of independently applying a variable pressure to each end of the pressure roller. It would be an advantage for the means of pressure to consist of the same means of pressure roller movement.
  • this invention consists of at least one support roller arranged so that it rotates with respect to a shaft in a fixed position with respect to a fixed position in relation to an edge of the support surface where a cylindrical working surface of the said support roller is level with the support surface and facing a cylindrical working surface of the pressure roller.
  • the means of forward movement include some means of drive designed to rotate the support roller, the pressure roller, or both at the same time.
  • the device could include more than one pressure roller and more than one support roller, preferably forming pairs.
  • One or more continuous belts could also be included mounted on two or more pressure rollers or on two or more support rollers.
  • An electronic device is preferably employed to independently govern the operation of the said liner movement pressure roller motor units in a synchronised fashion, included control of the pressure exercised on the slab by the pressure roller in accordance with the operational control of the drive for the means of advance movement.
  • This device drive control can be made in accordance with previously programmed sequences, or according to parameters detected by sensors or a combination of both.
  • the main advantage of the device described in this invention is that the pressure roller must only be lifted when the slab is first introduced. From this point, the pressure roller can remain in permanent contact with the slab and apply a lower pressure when the slab is being moved in the forward direction and then, when the slab is detained, can apply a greater pressure in order to firmly hold the slab in place while it is being machined by the treating apparatus.
  • the pressure and support rollers do not necessarily have to be motorised and could be freely rotating, in which case the device would have to include some auxiliary drive method comprising, for example, one or more moving clips or one or more pusher mechanisms.
  • a cylindrical working surface of the support and pressure rollers incorporates a surface treating or configuration designed to increase the friction or to mate with the slab material in order to ensure its correct movement.
  • This surface treating or configuration may include, for example, a more or less deep milling, perforation or even a large number of needles set out so that they penetrate into the cork slab.
  • the unit is a slicer that comprises a support surface 5, fitted to a frame 30 and a treating apparatus 6 (shown in trace lines in Fig. 1 ) operationally located with respect to the support surface 5.
  • the mentioned treating apparatus 6 includes a motor-driven cutting disc or blade, together with some stops 2 located at a predetermined distance from the cutting disc 1, which corresponds to the width of the slices to be cut.
  • the device in accordance with this embodiment consists of a support roller 10 arranged to rotate with respect to a shaft located in a fixed position in relation to an edge of support surface 5, so that a cylindrical working surface of the said support roller 10 is level with the support surface 5, or slightly above it and facing a cylindrical working surface of a pressure roller 20 arranged to rotate with respect to a shaft installed in an adjustable fashion in relation to support surface 5.
  • a pair of rectilinear guides 31, 32 fixed to frame 30 is installed next to ends 21, 22 of the pressure roller 20.
  • a pair of moving supports 35, 36 are arranged to slide along guides 31, 32 respectively and are connected to corresponding linear operating motor units 37, 38, each of which has a fixed part connected to the frame 30 and a moving part connected to the corresponding moving support 35, 36.
  • each end 21, 22 of the pressure roller 20 is installed so that they can rotate in their respective sliding supports 23, 24 and each of these sliding supports 23, 24 is, in turn, linked in a sliding fashion to a respective pivoting support 33, 34 articulating with one of the mentioned moving supports 35, 36.
  • the sliding of shafts 25 joined to the sliding supports 23, 24 in corresponding orifices in the pivoting supports 33, 34 absorb any differences in length produced by the inclination of the pressure roller 20.
  • the activation of the said linear motor units 37, 38 in one or the other directions produces an independent movement of the ends 21, 22 of the pressure roller 20 to move the same closer to or further away from the mentioned roller support 10 with interposition of at least one of the said slabs P.
  • the installation of moving supports 35, 36 permits a variation of pressure roller 20 inclination to adapt to any irregularities in slab P thickness.
  • the linear motor units 37, 38 form the means of roller movement and can consists of, for example, pneumatically or hydraulically driven piston and cylinder assemblies or of electric motor and spindle.
  • An electronic device is included to independently control operation of the said linear motor units 37, 38, which allows, for example, the independent control of the holding movements of the ends 21, 22 of the pressure roller 20, together with the pressure applied to each end 21, 22 during the various stages of the operating cycle.
  • the support roller 10 may be omitted and, in this case, the slab P is held in place between the pressure roller 20 and the support surface 5.
  • the pressure roller guidance system 20 at its ends 21, 22 by means of the rectilinear guides 31, 32 means that the pressure roller 20 shaft and the said guides 31, 32 are maintained in the same transversal plane to the support surface 5 at all times. If the device includes the support roller 10, its shaft is also in this same transversal plane to the support surface 5.
  • other guidance elements are possible, such as, pivoting arms that define other paths, for example, curvilinear.
  • the device also includes the means of forward movement designed to advance the slab P over the support surface 5 and through the action of the pressure roller 20, towards the treating apparatus 6.
  • These means of forward movement could consist of an auxiliary drive system (not shown) comprising, for example, one or more moving clips or by one or more pusher mechanisms.
  • the means of advance movement consists of a geared motor unit 39, connected so that it rotates the pressure roller 20.

  • the previously mentioned electronic device is also designed to independently control the said geared motor units 39, 40 for driving the pressure and support rollers 20, 10 in a synchronised manner, respectively.
  • the motorised operation of both support and pressure rollers 10, 20, as shown in the figures, provides high drive capability.
  • the means of advance movement may only include the support roller 10 drive or only the pressure roller 20 drive.
  • the electronic device will be designed to independently control operation of the motorised roller in synchronisation with the linear operation motor units 37, 38.
