Definitions

  • This application relates to the field of equipment for producing footwear.
  • a brush is fitted to a horizontal rotating shaft which is part of a machine.
  • the operator applies a wax polish to the brush and then causes the footwear article to approach said brush, while turning it in such a way that the whole surface thereof is evenly polished.
  • the operator engaged in polishing also carries out retouching, that is, the correcting of any defects in the footwear.
  • the machine must be stopped at intervals so that the operator can see to retouching the footwear.
  • a first drawback with the prior art is that the polishing operation takes up all of the operator's attention. Therefore, when the operator is engaged in polishing, he cannot carry out retouching and when engaged in the latter operation, he must stop the polishing machine.
  • a second drawback is that with known machines the polishing operation generates dust, much of which is inhaled by the operator.
  • the objects of this present invention are to make the operation of polishing easier and simpler, reduce the amount of pollution in the working environment and cut production times.
  • abowe said objects have been realised with a machine or apparatus for polishing, comprising two brush-bearing hubs spaced apart near one another and suitable for holding and rotating a brush, conveyor means for moving a footwear article along a path running between the brushes on the hubs and driving means for turning said hubs, preferably with a reversible rotary motion.
  • the brushes are enclosed in a protective casing, fitted with a suction device. Provision is made for enabling the brushes to be displaced between a position near to one another and a position at a distance from one another.
  • the conveyor means for the footwear comprises a device composed of a rod with one end for engaging the footwear, means for moving said rod between a lowered position engaging said footwear and a nonengaging raised position and means for moving said rod along a path between the brushes.
  • the footwear is displaced while lying on a sliding belt or mat. A part of the path for the footwear slants or is inclinable with respect to the horizontal plane, such that the footwear can be placed against the brushes in a tilted position.
  • the apparatus also comprises a means for applying polish made up of a polish-holding rod, on which is fitted a stick of polish, and a support for the rod, the support being movable between a working condition in which the stick is placed between the rotating brushes and a rest condition in which the stick is removed from the brushes; or the apparatus comprises a spray device for spraying abrasive finishing liquid onto the surface of the brushes.
  • a counter-rotating . motion is provided for the brushes, in one direction along a section of the footwear article and in the opposite direction along a further section thereof, such that the parts of the brushes in contact with the surface of the footwear are always moving towards the centre thereof.
  • brushes are provided which are oblong in shape, seen in plan view, the main radius of the oblong shape being longer than the distance between the brush's axis of rotation and said longitudinal centre line in the path and the minor radius of the oblong shape being shorter than said distance.
  • Said brushes are arranged to be staggered in rotation, that is to say, their main axes are staggered by 90° with respect of one another.
  • the new apparatus allows footwear to be polished automatically with a saving in time, in as much as all the operator has to do is position the footwear article and this being done, he is able to carry out retouching another footwear article.
  • the footwear are polished more uniformly and working conditions are more healthy.
  • the polishing machine indicated globally by 10 in the Figs., comprises a pair of brush-bearing hubs placed near to one another, 12 and 14 respectively. It is preferable for the hub axes to lie in a vertical plane. Each of the hubs is shown with its respective brush 16, 18, which is attached to the hub so as to revolve therewith, but also so as to be easily removed therefrom along the axis.
  • the brushes 16, 18 shown in Fig. 1 are of the traditional type with a central body and a set of radially arranged bristles. The outline of the set of bristles is circular in shape, seen in plane view.
  • bristles are meant hairs of animal origin, cotton or wool
  • each circular brush is about half the distance I between the brushes' centres, such that the brushes are basically tangential to one another and both tangential to a theoretical line 72' along which the footwear article C to be polished travels, as eaglained below.
  • R the major radius
  • I the distance between the brushes' centres
  • R+r I.
  • Each hub is integral with its respective first shaft 20, 22 and each first shaft 20, 22 is integral with a second shaft 28, 30 by means of an articulated joint, 24 and 26 respectively.
  • the shafts 28, 30 are held vertical by means of supports 32, 34 and brackets 36, 38 fitted with ball bearings, such that shafts 28, 30 can each rotate on its own basically vertical loag Congressal axis.
  • a gearwheel, 40 and 42 On each shaft 28, 30 (Fig. 3) is fitted a gearwheel, 40 and 42 respectively.
  • a toothed belt 43 or other similar drive means, links the gearwheels 40 and 42 to one another in such a way that they rotate in opposite directions.
  • Said toothed belt is made taut by a tightener 44.
  • a motor 45 drives the belt 43 in the direction of the arrow F 1 or that of the arrow F 2 , and in this way a counter-rotating motion, both in one and the opposite direction, is imparted to the brushes.
  • an approaching device 52 generally composed of a cylinder-piston unit 53, having the end of the cylinder fixed to shaft 22 and the end of the rod fixed to shaft 20.
  • the position of maximum approach of the brushes can be regulated by means of the device 55, which includes limit stops, 56, extending orthogonally in the plane of Fig. 2 to act as an abutment for shafts 20, 22.
  • Each stop is fitted on a threaded sleeve, for example 57, operated by a supported screw rod 58 rotating on a fixed frame 60.
  • a protective casing 62 enclosing the machine is fixed to supports 32, 34 by means of brackets 63 and bears the above-said frame 60.
  • a handwheel 64 is for adjusting the stops 56.
  • the casing 62 extends upwards to form front 65, 65' and back 66, 66' walls protecting the brushes (Fig. 1).
  • Covers 67, 68 pivoted on hinges are fitted onto the upper part of the casing 62.
  • the walls 65, 66, 65', 66' and covers combine to enclose each brush in a box, such that only the side facing the opposite brush is left open.
  • Flexible closing flaps, 69 are placed between walls 65 and 65' and walls 66 and 66'. In this way the brushes are enclosed within a chamber, from which harmful dust cannot escape.
  • a suction outlet 106 is connected to a suction-filtering device of a known type, not shown.
  • a footwear article lies on a belt 72 extending along the path indicated by 72' and passing around idle rollers 74. It is preferable for the upper path of the belt to be supported by a plate 73 covered with a frictionless material.
  • the belt 72 basically extends horizontally to a position near the brushes axes. A fixed surface covered by a mat made of frictionless material may be provided in place of the moving belt 72. The footwear article is moved along the mat (or together with the belt) using means explained below.
  • the following part of the footwear article's path is composed of an upward slanting section, 75, achieved by fitting a swinging board 76, hinged at 76' and moved by means of a cylinder-piston 77 between a lowered position, in which said board is coplanar with plane 78 of the machine, and a raised position, slanting at about 30° with respect to said plane.
  • a belt or mat 79 is placed on board 76 with one end fastened near hinge 76' and the other end to a return spring 79'.
  • the device comprises a rod 80 for moving the footwear forward having at its end a means 81 for engaging the footwear, said rod moving between a raised position, not engaging the footwear (chain in Fig. 4), and a lowered position engaging the footwear (continuous line in the same Fig.). It also moves along the means 72 and between the brushes, thereby causing the footwear to move forward.
  • the footwear-engaging means 81 may be formed by a point (as in Fig. 4) for engaging a notch in a shape inside the footwear, where polishing is preferred with the footwear fitted around a shape, or it may comprise a foot (not shown) for engaging the bottom of the footwear, made to advance without a shape; or lastly (Fig. 5), it may comprise an element 81a pivoted to the rod.
  • the rod 80 is held in a clamp 82, held in turn by a bar 83 in such a way as to be adjustable lengthwise.
  • Said bar is held pivoted to a vertical column 84, which is integral with a sleeve 85 sliding on a horizontal rail 86, supported by the machine's casing or housing.
  • a longitudinal opening 84' in the surface 78 allows the column 84 to slide.
  • a cylinder-piston unit 87 acts between a bracket 88, integral with the vertical column 84, and an extension 83' of bar 83 in order to move said bar 83 between a lowered position (continuous line in Fig. 4) and a raised position (chain in Fig. 4).
  • a horizontal longitudinal motion is imparted to column 84 by a cylinder-piston unit 90 fixed to the machine housing through a crank 91, pivoted at a fixed point 92, on which a rod hinged to sleeve 85 slides in contact with sleeve 93.
  • the limit positions of device 80 are indicated by broken lines and continuous lines respectively in Fig. 4. Therefore, rod 80 can carry out a forward horizontal movement and a movement of raising and lowering.
  • a horizontal arm 96 is fixed to the vertical column and holds a throw 97, with which a rod 98 holding a stick of polish 100 is made integral.
  • a cylinder-piston unit 102 provides for displacing the stick of polish between a raised (continuous line in Fig. 4) and a lowered condition (broken line in the same Fig.).
  • a cantrol panel 104 for the machine is indicated by a thin line.
  • a footwear article C to be polished is placed on means 72 with its back facing in the forward-moving direction and the rod 80 is lowered to engage the footwear article.
  • the cylinder-piston 77 actuates raising of the board 76.
  • rod 80 which has hooked the footwear, advances slowly bringing it towards the moving brushes.
  • the cylinder-piston 102 lowers the stick of polish between the brushes before the footwear arrives, such that the work surfaces thereof are covered with polish.
  • the stick of polish has been raised from the brushes into the rest position.
  • rod 80 is moved forward slowly by means of the cylinder-piston 90 and brings the footwear, sliding with the belt 72 on the frictionless surface 73, between the brushes.
  • the brushes covered in polish rotate in opposite directions with regard to one another and change their direction of rotation, when they reach the approx. halfway point of the footwear article; that is to say, the surfaces of the brushes always act on the footwear with a movement towards a line crossing the center of the footwear article. In this way the back and sides of the footwear are fully polished.
  • other ways of rotating the brushes are possible within the field of the invention, for example alternate rotation. Having reached the slanting section 75, the footwear presents the top of its upper to the brushes and this is also polished.
  • a suitable stop ensures that cylinder-piston 77 lowers or causes board 76 to be lowered.
  • rod 80 ends at the position shown by a broken line in Fig. 4, where the rod is raised and the operator removes the footwear article. In the raised position the rod travels back as far as the position shown by a continuous line in Fig. 4, being lowered automatically to hook another footwear article to be polished, which has been positioned by the operator.
