Definitions

  • the invention relates to an abrading device for abrasion of substantially plane items according to the preamble of claim 1. See, for example, document EP 1 175 961 A2 ..
  • the roll is brought to rotate about its longitudinal axis and the rotating abrading tool is brought into contact with the surface, whereby a gentle abrasion may take place.
  • This abrasive method is gentle due to a low abrasive pressure but it may be a slow abrasive process in relation to abrasive tasks on a general plane face having shapings, e.g., a door. In this case, it is necessary to move the abrading tool in a complicated movement around along the shapings to ensure a complete abrasion of these. In this connection it is also of great importance which rotational direction the abrading tool has in relation to the profile curves. The result is that the conduction of the abrasive task becomes slow and at the same time may be difficult to fully automate which also makes the tool inefficient seen from a production cost view.
  • the present invention relates to an abrading device for abrasion of substantially plane items in accordance with claim 1.
  • abrading discs By moving the abrading discs in an oscillatory or reciprocatory movement transverse to the direction of feed of the items it is achieved that traces etc. from the different abrasive properties of the abrading discs across the diameter of the disc are eliminated as well as all parts of milled out areas etc. are abraded evenly by applying abrading discs with abrasive means which comprise abrasive lamellae of an abrasive sheet, such as abrasive cloth where the surface of which has abrasive properties and which extends from the face of the abrading disc.
  • abrasive means which comprise abrasive lamellae of an abrasive sheet, such as abrasive cloth where the surface of which has abrasive properties and which extends from the face of the abrading disc.
  • Such abrading discs are, e.g., described in US-A-4,493,170 , in DE-A-24 11 749 and in EP-A
  • the suspension means for suspension of the abrading discs is preferably made as one single structure so that the reciprocatory movement of all the abrading discs can be driven by the same drive means.
  • This or these means may typically be an electrical or hydraulic motor, which drives rotation of an axis with an eccentric attachment to the suspension means but may, e.g., instead consist of an elastic suspension of the suspension means and a solenoid which is turned on and off at a given frequency by a relay, thus performing regularly changing forces between the suspension means and a stationary part of the abrading device.
  • This reciprocatory movement transverse to the direction of feed of the items is preferably a substantially strictly transverse movement but may also, e.g., comprise a circular or elliptical shaped movement of the abrading discs as long as the movement pattern includes said reciprocatory movement.
  • the reciprocatory movement of the abrading discs has in one embodiment preferably a length of stroke of 40-100%, preferably 60-85%, of the diameter of the discs to eliminate the tendency to groove formation. By length of stroke is understood the distance between the two extreme positions in transverse direction of the centre axis of an abrading disc.
  • the abrading device may advantageously comprise a plurality of abrading discs with undercut grooves for reception and fixing of profile rails which form a part of elongated abrasive elements comprising abrasive means, said grooves preferably extend in a mainly radial direction on the face of the abrading disc.
  • the abrading discs can receive elongated abrasive elements which consist of abrasive means in the form of lamellae of abrasive cloth of which the front side has abrasive properties and the back side is supported by support elements being elastic in the tangential direction of the disc, so that the front side of the abrasive cloth is pressed into abutment with a relatively high abrasive pressure with the surface to be abraded and thus the abrasion can take place at low feed velocity of the abrasive element, i.e.
  • the support elements are preferably brushes, e.g., natural brushes, which extend from the face of the disc in a shorter distance than the abrasive means so that the support elements are not normally in contact with the item.
  • the abrasive means and support elements are secured in a profile rail with a cross section corresponding to the cross section of the grooves such that the abrasive elements are easily pushed into and retained by the grooves and also easily removed from them whereby a replacement of worn abrasive elements or a conversion of the device to another kind of processing with other abrasive elements is easily performed.
  • Suitable kinds of abrasive elements are described in, e.g., WO-A-01/76824 .
  • holding elements may be arranged between the abrasive elements in order to limit the deflection of the abrasive means.
  • the effect of the holding elements is that the abrasive means at a certain deflection thereof become engaged with the holding element at the back, which results in an increased stiffness of the abrasive means and thereby requires greater force for further deflection.
  • the holding elements preferably comprise a holding brush having a shorter length than the abrasive elements and which is mounted in a profile rail, which is received in a corresponding undercut groove on the face of the abrading disc.
  • the means for driving the rotation of the abrading discs is normally arranged in such a way that all abrading discs are rotated the same way.
  • adjacent abrading discs are rotated in the opposite direction which in combination with the reciprocatory movement of the abrading discs results in a more uniform abrasion of all parts of the item surface.
  • the plurality of abrading discs may preferably be arranged so that they are aligned transversely to the direction of feed of the items.
  • the plurality of abrading discs are arranged in two consecutive rows transversely to the direction of feed of the items, wherein the discs in one row are staggered with respect to the discs in the other row.
  • the length of stroke may be reduced and is preferably a magnitude of 20-50%, preferably 30-43%, of the diameter of the discs.
  • the at least one abrading cylinder is arranged after said side has been abraded by the abrading discs but may alternatively be arranged before, so that the items meet the cylinder prior to the abrading discs.
  • An abrasion with rotating abrading discs can be relatively aggressive as there will be some transversal abrasion of the items and the device is typically designed for a relatively high abrasion pressure and low rotational speeds of the abrading disc in order not to deform possible shapings in the work piece.
  • some "wild" abrasive scratches will occur due to the rotation but these will be removed by the one, two or more abrading cylinder, which will, typically, be equipped with a rougher grit size than the abrading discs.
  • the machine may be constructed with an extra similar module with a plurality of abrading discs in order to leave out the abrading cylinders.
  • the abrading device 1 comprises a conveyor belt 2 driven continuously or stepwise by a motor 3 and is used to convey substantially plane items through the abrading device 1 from a feed end 4 in a direction of feed indicated by the arrow A on Fig. 1 .
  • the upper side of the item contacts with six abrading discs 5 arranged in a row which is transversal in relation to the direction of feed of the item and where the abrading discs 5 are rotated clockwise and counter-clockwise alternately such that two adjacent abrading discs 5 are rotated in separate directions as indicated by the arrows B-G on Fig. 1 .
  • the drive of the abrading discs 5 may also be arranged such that all the abrading discs 5 rotate in the same direction.
  • the abrading discs 5 are mounted on a slide 10 which during operation is moved in a reciprocatory movement as indicated by the arrow H on Fig. 1 , where the movement has a length of stroke so that the extreme positions of each of the abrading discs 5 centre positions in the reciprocatory movement are situated with a mutual distance of 75% of the diameter of the abrading discs 5.
  • Each abrading disc 5 consists of a disc 6 which, on the bottom side facing down towards the item, has a plurality of undercut, radially running grooves (not shown) in which abrasive elements (not shown) are received comprising a profile rail which retains a number of abrasive lamellae of which the front side has abrasive properties and of which the back side is supported by a number of support brushes.
  • the abrasive lamellae extend downwards from the disc towards the item substantially perpendicular to the rotation plane of the disc.
  • a suitable type of such abrasive lamellae consisting of profile rail, abrasive lamellae and brushes is, e.g., described in WO-A-01/76824 .
  • the abrasive elements are orientated in such a way that the front side of the abrasive elements with the abrasive properties are at the front in the rotational direction.
  • the abrasive elements are secured on the disc by the interaction between the profile rail and the undercut grooves having a dovetailed cross section of the opening, and by a ring, which extends around the periphery of the disc and closes the open end of the rails at the periphery of the disc. This ring is removable after which the abrasive elements can be pushed out of the grooves and new abrasive elements can be pushed in.
  • the items After having passed the abrading discs 5 the items are transported further on the conveyor belt 2 under two opposite rotating abrading cylinders 7, 7' which remove possible scratches in the surface of the items and give the surface the final finish.
  • the abrading cylinders 7, 7' are driven by associated motors 8, 8'. Suitable abrading cylinders are, e.g., described in WO-A-01/76824 .
  • the conveyor belt 2 conveys the items out of the abrading device at its exit end 9.
  • the abrading discs 5 are mounted on a common slide 10 which is movable in transverse direction in relation to the direction of feed of the items in as much as the slide 10 comprises two rails 11 that run in three sets of wheels 12 which are securely mounted on a transverse beam 13 which is secured to the frame 14 of the abrading device 1.
  • Each abrading disc 5 is mounted on a vertical axle 15, which is embedded in the slide 10 with bearings 16 such that it turns freely about its vertical axis with minimal friction.
  • the axle 15 extends through the slide 10 and has at its upper end a pulley 16 to cooperate with a v-belt 17 for driving the rotation of the abrading discs 5.
  • All abrading discs 5 are driven by a motor 18 mounted on the slide 10, which has a pulley 20 mounted on its driving axle 19.
  • the extension 21 of the abrasive lamellae in vertical direction is indicated.
  • the reciprocatory movement of the slide 10 transverse to the direction of feed of the items is driven by a separate motor 22 via an eccentric mechanism 23.
  • the abrading discs 5, 5' are arranged in two successive rows transversely to the direction of feed A of the items, and the discs 5 in the first row are staggered with respect to the discs 5' in the second row. All the discs 5, 5' are arranged on a common slide 10 which, due to the staggered arrangement, during operation is moved in a reciprocatory movement as indicated by the arrow H on Fig. 1 , with a length of stroke of about half of the magnitude of the embodiment shown in Fig. 1 , i.e. the extreme positions of each of the abrading discs 5, 5' centre positions in the reciprocatory movement are situated with a mutual distance of about 35-40% of the diameter of the abrading discs 5, 5'.
