Definitions

  • the present invention relates to an apparatus for manufacturing shoes.
  • these machines are usually made up of a support frame adapted to hold a work head provided with a tool designed for a particular working (rivetting, roughing, gluing or cementing, etc.).
  • Apparatus of known type are further equipped with a device for shoe support and locking designed to enable a correct positioning and fastening of the shoe to be manufactured.
  • the same is provided with the appropriate degrees of freedom and the respective tool for carrying out the working itself.
  • the apparatus dedicated thereto will be provided with a toolhead on which a disc is mounted which has a suitable abrasive surface.
  • the head will be also equipped with appropriate motors and motion-transmitting members capable of setting the roughing tool in quick rotation about its transverse axis and will also be provided with the appropriate members adapted to rotate the tool about an axis orthogonal to the rotation axis through varying angles, until a value of ⁇ 360°.
  • EP 0596570 a carding-cementing machine for shoes, which comprises a pair of supports respectively bearing one shoe to be worked and where two working heads are disposed above said supports.
  • the first head presents a carding tool
  • the second head presents a cement-delivering tool
  • the supports and the working heads are mutually movable so that the carding tool can travel over a predetermined path on the bottom of a shoe (disposed on the first support), while the cementing tool can travel over a predetermined path on the bottom of a second shoe disposed on the second support.
  • the mutual positions between the supports and the working heads can be interchanged with each other.
  • the apparatus will be then programmed in such a manner that the tool can follow the shoe outline to remove material therefrom where necessary and required.
  • each machine is accomplished so that it may be dedicated to performing a precise working on the shoe and for this reason the only operating flexibility of the machine consists in the possibility of carrying out the same working on different shoe typologies and conformations.
  • a roughing-cementing machine for shoes which is provided with two shoe-fastening supports each of which is arranged to lock a respective shoe to be processed.
  • Two independent work heads are positioned above the supports and are provided with a cementing tool and a roughing tool respectively.
  • Each support and the respective work head are also movable relative to each other in such a manner that the roughing tool can follow a predetermined path of travel on the lower surface of the shoe disposed on the first support and the cementing tool can cover the same way on the surface of the second shoe.
  • the two heads carrying the two tools are therefore independent of each other in their movements and their positions can also be exchanged in such a manner that the first tool can operate on the second shoe and the second tool can carry out the working for which it is intended on the first shoe.
  • the two work heads As regards planning too, due to the necessity for the two work heads to be interchangeable, said heads must be built in such a manner that they do not interfere with each other, either during the working operations or during the movement steps of the heads themselves. As a result, the support heads cannot be made using components that are very stout from a structural point of view.
  • the present invention aims at substantially obviating all drawbacks of the known art.
  • An auxiliary aim of the invention is then to make available an apparatus provided with many degrees of freedom so that the active surface of the tools can be conveniently adapted to and positioned on the shoe to be processed thereby obtaining more precise workings.
  • the apparatus for manufacturing shoes 5 in accordance with the invention comprises a support frame 2 only partly shown in the figures in order to enable a better sight of the different parts forming the device itself.
  • the support frame 2 is designed to receive in engagement at least one shoe-supporting device denoted by 3.
  • the shoe-supporting device 3 has been shown only diagrammatically because it can be made in a great number of manners known by themselves and used in the presently available machines.
  • shoe supporting device will be provided with shoe-locking means 4 which is movable between at least one operating condition in which shoe 5 is kept in position so as to be able to carry out a particular working thereon and a second operating condition in which shoe 5 is released for the necessary loading-unloading operations of the apparatus.
  • the locking means 4 too has been shown only diagrammatically as it is of a known and conventional type.
  • the shoe-supporting device 3 used in the present invention is provided with at least two degrees of freedom, i.e. it is movable relative to the support frame 2 in at least one direction Z and a second direction Y, which directions are transverse to each other.
  • the first movement direction Z of the support device 3 is coincident with a substantially vertical axis whereas the second movement direction Y lies in a substantially horizontal plane.
  • Apparatus 1 also has at least one first and one second working tools 7, 8 arranged to operate on a shoe 5 to be processed and which are both mounted on a head block 6.
  • the head block 6 too is in engagement with the support frame 2 and, in detail, is movable in its entirety at least along a movement direction X lying in a substantially horizontal plane.
  • the movement directions X of the head block 6 and Y of the support device 3 are transverse to each other and in particular mutually perpendicular; in this way shoe 5 to be worked and tools 7, 8 mounted on the apparatus will be moved relative to and with each other in three Cartesian axes X, Y and Z.
  • both the first 7 and second 8 tools will follow the head block 6 itself during its translation along axis X.
  • the head block 6 is made up of a bearing body 9 directly in engagement with the support frame and in particular designed to traverse along a predetermined number of slide guides 10.
  • the bearing body 9 in turn carries a work head 11 mounted on said body in an oscillatable manner. More particularly, the work head 11 is pivotally mounted to one end of the bearing body 9 at an oscillation axis W.
  • At least one of the tools 7, 8 (but preferably both of them in the configuration shown in Figs. 1-6) has a substantially disc-shaped conformation.
  • such tools are in fact designed to be set in quick rotation around a respective longitudinal axis 7a, 8a in the direction identified by the arrows in Fig. 1.
  • the working tools 7, 8 can be driven in rotation about a respective axis 7b, 8b parallel to the machining axis (see Fig. 1).
  • the longitudinal rotation axis 7a, 8a of the disc-shaped tools is transverse, preferably orthogonal, to the machining axis.
  • each of the two tools carried by the work head is capable of traversing along axis X, oscillating about axis W, rotating about a longitudinal rotation axis 7a, 8a of its own, as well as of rotating through ⁇ 360° about an axis 7b, 8b parallel to the machining axis.
  • the shoe-supporting device 3 is capable of moving shoe 5 relative to tools 7, 8 along two transverse axes Z and Y.
  • the invention is also suitably arranged for interchangeability of the tools either to replace the tools possibly worn out, or to modify the machine operation (type of working).
  • the machine can be set for execution of roughing-rivetting operations.
  • the same apparatus after replacement of the tools and tool-carriers, can be converted to a roughing-cementing machine (see Fig. 12).
  • the apparatus of the present invention will be adapted, after mounting the appropriate tools thereon, to operate as a rough-shaping-rivetting, rough-shaping-cementing, rough-shaping-roughing machine or at all events to operate according to any combination of workings (which obviously will depend on the type of tools 7 and 8 mounted to the apparatus itself).
  • the apparatus is able to obtain the above described degree of versatility while maintaining the relative basic movements between the tool and shoe without replacement of other parts of the machine being required and with a minimum number of mechanical components.
  • the cement-applying or cementing tool 8 will carry a motor mounted thereon and dedicated to rotation of a brush and will be also able to oscillate about an axis parallel to axis 8a.
  • One of the features of the present invention is then that of giving the working tools 7, 8 all the above described movements although no motor is mounted on the work head 11 (except for the rotation motor for the cement-applying tool); this for the purpose of avoiding the motors themselves being submitted to the oscillations of the work head 11, as well as avoiding too heavy a weight being present on the head itself.
  • actuating means 12 is associated with frame 2 and is activated to enable a relative displacement between the shoe-supporting device 3 and the working tools 7, 8.
  • the actuating means 12 comprises transmission systems designed to allow an efficient motion transmission while enabling the work head to oscillate.
  • the actuating means 12 designed to give a rotatory motion to axes 7a, 8a of the tools mounted on the work head 11 consists of a motor 13, first motion-transmitting members 14 which are able to transfer motion from motor 13 to at least one pulley 15 mounted on the work head 11, and second motion-transmitting members 16 which are able to transfer motion from pulley 15 to the first and second working tools 7, 8 (see in particular Figs. 6 and 7).
  • the work head 11 is also provided with positioning means 22 active on each of the working tools 7, 8 to bring an active portion 23 thereof close to a working plane preferably containing the oscillation axis W of the work head 11.
  • This positioning means 22 further comprises an actuating device (not shown) active on the connecting rods 24, 25 to cause raising/lowering displacements of the active portion 23 of tools 7, 8, as indicated by an arrow still in Fig. 7.
  • the second motion-transmitting members 16 comprise, for each tool, a rotating head 29 set in rotation via a belt 30 by pulley 15 mounted on head 11 and a first shaft 31 suitable to receive a rotatory motion from the rotating head 29 and provided with an inner cavity 32 (see Figs. 7 to 10, in particular).
  • a second shaft 33 slidably engaged in cavity 32 in the first shaft 31 is provided with shaped expansions 34 (in particular a three-lobe shaft is used) capable of transmitting a twisting moment and enabling an axial sliding of the telescopic type between the two shafts.
  • shaped expansions 34 in particular a three-lobe shaft is used
  • At least one and preferably two flexible connecting elements 35 are provided; said flexible connecting element is adapted to enable relative displacements in a vertical plane between a rotation axis 36 of head 29 and a rotation axis 37 of the shaft transmitting motion to the tool.
  • such elements will consist from a structural point of view, of a disc made up of a first layer of rigid material 35a, a second layer of flexible material 35b directly in engagement with the first layer and a third layer 35c of rigid material in engagement with the flexible material.
  • the actuating means 12 is equipped with a motor 38 operatively associated with the support frame 2 and a flexible motion-transmitting element 39 for each tool which is adapted to receive the rotatory motion from motor 38 and to enable transferring of same to tools 7, 8 that are oscillatably mounted on the head block 11 (see Fig. 11).
  • the rotatory motion from the reduction gears of a motor is caused to pass through a bevel gear pair interposed between motor 38 and the flexible element 39 (a first gear of the bevel gear pair receives the rotatory motion from the motor and transfers it to a second gear integral with the flexible element).
  • the flexible element 39 then transfers motion to a rotating head 40 directly mounted on the oscillating work head 11, as shown in Fig. 8.
  • a flexible element 39 (a steel cable or other appropriate element) allows transmission of a rotatory motion from motor 38 which is mounted on the head block 6 and therefore does not oscillate, to a work head 11 capable of carrying out angular displacements of important amounts.
  • the actuating means 12 comprises a motor, preferably an electric one, mounted at either tool 7 or 8; such an electric motor will transmit motion to a tool due to a first transmission gear, whereas through a Cardan shaft (or, more generally, an equivalent transmission apparatus) extending between the two tools 7 and 8 it will transmit motion to the second tool too.
  • a motor instead of arranging a motor connected to the fixed part (i.e. the support frame 2) of the apparatus, a motor is set that moves integrally with one of the movable parts of the apparatus itself.
  • the flexible cable 39 transmits motion to a reduction motor of the worm screw type 48 which in turn transmits it to a disc 49 movable in rotation and suitable to cause oscillation, through a connecting rod 50, of a pivotally-mounted bar 51 rigidly connected to the cementing tool 8 so as to give the latter an oscillatory motion about axis 8c parallel to axis 8b (arrow 52).
  • Position of axis 8c can be conveniently selected based on the operating requirements; in particular, it is possible to cause positioning of axis 8c at the head portion of the cementing tool (in this case it will be a substantially horizontal ideal oscillation axis). Due to this particular choice, which is implemented through an appropriate kinematic mechanism for movement of the cementing tool, an excellent contact of the head portion of the tool itself (which practically carries out spreading of the glue or cement on the shoe being worked) as bending of the different shoe regions varies, is ensured and at the same time arrangement of complicated mechanisms is not required.
  • the head portion of the cementing tool can move with a pendular movement about axis 8c (in this connection see the accompanying figures).
  • the apparatus for shoe manufacture in accordance with the present invention is further provided with additional advantageous features for correct operation of same.
  • damper means 41 interposed between the work head 11 and bearing body 9 to avoid generation of undesirable vibrations during the oscillation movements of the work head 11.
  • damper means 41 interposed between the work head 11 and bearing body 9 to avoid generation of undesirable vibrations during the oscillation movements of the work head 11.
  • vibrations in the work head 11 were generated in particular at the positions of maximum inclination of the latter, which vibrations were transmitted to the working tools 7, 8 thereby giving rise to imprecise and inexact workings.
  • the damper means 41 is made up of a cylinder 42 associated with the work head 11 and provided with a cavity filled with a viscous fluid, such as oil for example, and inside which a slider 43 is movable which is rigidly linked to a rod 44 directly in engagement with the bearing body 9. Slider 43 together with the inner wall of cylinder 42 defines two regions in the cavity that are in fluid communication with each other through a blow-by space 45.
  • slider 43 moves within cylinder 42 and gives rise to oil blow-by through the foramina created between the inner wall of cylinder 42 and slider 43.
  • the reaction forces generated as a result of the oil passing through the blow-by space are of such a nature that they prevent arising of undesirable vibrations during the oscillations of the work head 11.
  • the apparatus also comprises elastic means 46 disposed between the bearing body 9 and work head 11 and designed to become operating when the work head 11 is at a position of maximum oscillation (see Fig. 11).
  • the elastic means 46 is defined by a spring for example, which is proportionally compressed as the inclination angle of the work head 11 increases.
  • the elastic means 46 may comprise at least one pneumatic actuator (of the simple-action and/or double-action type); conveniently, pressure-adjusting means can be interlocked with this actuator, for establishing the appropriate operating parameters. For instance, the presence of a particular pressure reducer can be provided which acts on one of the two pneumatic chambers of the actuator so that pressure within said one chamber is maintained constant. More generally, by conveniently operating on the pressure-adjusting means it is possible to select the force exerted by the pneumatic actuator depending on the displacement of the work head 11.
  • the head block 6 can be provided with a casing 53 designed to surround the working tools at least partly so as to avoid spreading of the removed material as a result of machining, during the roughing operations for example.
  • a casing 53 will be preferably made of a transparent material so that the working operations on the shoe can be examined at any time.
  • a first and a second ducts 54 disposed laterally of the respective working tool 7, 8 can be then connected with casing 53.
  • Sucking means can create a vacuum in said ducts so as to take in the waste material abraded from the shoe surface or the vapours burst out from glues or cements.
  • a selecting device placed at the junction point between the two sucking ducts enables a respective sucking channel to be activated while suction is shut off on the other so that material or vapour removal from the work area may take place in the most efficient manner without the sucking means being doubled (see Fig. 13 in particular).
  • the selecting device to simultaneously act on both sucking ducts, shutting down the suction flow thereof. More generally, depending on the particular requirements, the sucking ducts can be either both opened or both closed or only one of them can be opened; these four possible operating conditions can be selected in any manner through the selecting device.
  • the apparatus in accordance with the invention can be provided with more than one shoe-supporting device 3 to enable the loading-unloading operations to be carried out simultaneously with the working operations on another shoe, thus further increasing the production speed.
  • the invention achieves important advantages.
  • the apparatus of the invention is adapted to allow the head block - shoe-supporting device to have at least six degrees of freedom along respective axes for each working tool using a minimum number of motors and movable parts, thus increasing the device reliability.
  • the invention is also advantageous in its most specific aspects.
  • a single fan can offer an excellent sucking action selectively on one or the other of the two sucking ducts thereby ensuring an efficient cleaning of the regions submitted to machining.
