Definitions
- the general object of the present invention is to obviate the above drawbacks by providing an automatic machine capable of carrying out both roughening and cementing operations, while at the same time optimizing the processing time by the simultaneous working of two shoes.
- a carding-cementing machine for shoes which comprises a pair of supports each supporting a shoe to be worked, a first and a second working head being disposed above said supports, the first working head comprising a carding tool and the second head comprising a cement-delivering tool, said supports and working heads being 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 cover 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 being interchangeable with respect to each other so that the carding tool may be also capable of travelling over a predetermined path on the bottom of a shoe disposed on the second support, while the cementing tool can follow a predetermined path on the bottom of another shoe disposed on the first support.
- a machine in accordance with the invention comprises a supporting frame 11 bearing two carriages 12, 13, each designed to receive a corresponding last or shoe to be made 14, 15 having its bottom turned upwardly.
- carriages 12, 13 are movable transversely of the machine extension along horizontal guide rails 16, 17.
- One working or carding head 18 and a second working or cementing head are present above the carriages 12, 13.
- the first working head 18 is movable horizontally in a direction longitudinal to the machine along guide rails 19 supported by a carriage 20 which in turn is vertically movable along guides 21 fastened to the frame 11.
- movement of the head 18 can take place by a lead-screw unit 22 operated by an electric motor 23, whereas the vertical movement of carriage 20 can take place by means of a second lead-screw unit 24 operated by an electric motor 25.
- the second working head 26 is on the contrary movable vertically along a vertical guide 27, in turn supported by a carriage 28 horizontally movable along guide rails 29 supported by the frame 11 and parallel to the guide rails 19.
- movement of the head 26 can take place by means of a lead-screw unit 30 operated by an electric motor 31, whereas the horizontal movement of carriage 28 can take place by means of a second lead-screw unit 32 operated by an electric motor 33.
- Carriages 12, 13 supporting the shoe are power driven to be movable along the respective guide rails 16, 17 between a receded position and an advanced position which are located to the farthest right and left ends respectively, as viewed looking Fig. 2.
- Means for actuating carriages 12, 13, not shown for the sake of simplicity, can consist of power driven screw-lead units, as described above with reference to the working head.
- shoes can be alternately brought to intersect the vertical planes parallel to each other in which the first or second head moves.
- the support carriages 12, 13 are identical with each other and comprise a base 34, 35 slidable on respective guide rails 16, 17.
- Each base 34, 35 carries a fixed rear support and a movable front support for the shoe. Also located on the base is a central reclining support.
- the rear supporting portion 38 comprises two grippers 39 for laterally tightening the shoe heel area.
- the central support portion comprises a post 36 adjustable in height, on top of which the shoe last carrying the shoe is fitted, said post being pivotally mounted at the rear part thereof according to an axis 41 enabling it to be tilted forward by means of an actuator 42, thereby moving from the upright position drawn in solid line in the figure to the inclined position drawn in chain line.
- the front support portion 43 comprises a slide 44 horizontally movable along guide rails 45 parallel to the shoe extension.
- the slide movement can be obtained by power driven screw-lead units not shown in the drawing for the sake of clarity.
- Grippers 40 are disposed on the slide 44 for laterally tightening the toe portion of the shoe, and also provided is a locking device 46 for the shoe toe.
- the device 46 comprises an actuator 47 designed to move it vertically.
- the slide 44 moves forward to the position in chain line and the central support is tilted forward for facilitating fitting (this is particularly useful in case of boots). After the shoe has been positioned on the central support 36, the latter goes back to the upright position, the slide 44 moves back towards the shoe and grippers 39 and 40 are tightened. The locking device 46 rises and entraps the shoe toe, which is therefore perfectly fixed.
- the toe locking device ensures the exact positioning of the shoe relative to the working heads.
- the head 18 comprises a rotating carding brush 54 movable along the periphery of the shoe bottom.
- Said carding head 18 being the object of an Italian patent application No.MI91A000950 in the name of the same Applicant, will not be described in detail but only enough to enable comprehension of the present invention
- the head 18 comprises a slide 48 for movement along the guide rails 19.
- Fastened to the slide 48 is a sleeve 49 for rotation of an arm 50 about a vertical axis 51 by means of actuators 52.
- the arm 50 carries a second arm 53 supporting the power driven carding rotating brush 54.
- the arm 53 is movable in the brush plane to enable said brush to rest on the shoe bottom while exerting a predetermined pressure.
- the arm 53 may also be rotated by an actuating means 55 to enable tilting of the brush plane about a tangency line of the brush to the shoe, so that the brush can be kept tangent to the shoe bottom while the tool is being moved.
- the axis 51 substantially passes through the contact point of the brush with the shoe bottom so that upon operation of actuators 52, the brush plane rotates through 180° about this contact point.
- the brush while rotating always in the same direction, has a rotatory movement at the tangency point with the shoe bottom which is always directed towards the inside of said bottom over the whole travel of the head along the shoe perimeter.
- the cementing machine 26 comprises on the contrary a nozzle 56 dispensing cement in a controlled manner.
- a nozzle 56 is surrounded by a spreading brush 57 rotatably moved about the nozzle axis by a motor 58 so that cement can be uniformly distributed.
- the nozzle is supported by a kinematic mechanism for its controlled tilting according to planes transverse and longitudinal to the shoe, so that the nozzle can be maintained always perpendicular to the shoe bottom while it is moving for carrying out the cementing operation.
- the cementing head 26 comprises a slide 59 slidable along a vertical guide 27.
- a first arched guide 60 extending in a plane transverse to the machine.
- Slidable on the arched guide 60 is a carriage 61 moved by an actuator 62 and supporting a second arched guide 63 extending in a plane longitudinal to the machine.
- Slidable on said second arched guide 63 is a carriage 64 driven by an actuator 65 and supporting the delivery nozzle 56.
- the bending centres of the arched guides are adapted to identify a rotation centre coinciding with the nozzle delivery end. In this manner, by moving the carriages on said guides, the nozzle tilts while at the same time keeping its outlet end fixed.
- control device 66 substantially of known type and therefore not shown in detail as it can be easily envisaged by a person skilled in the art.
- a control device may be embodied by an electronic microprocessor circuit suitably programmed, as will be apparent from the following description concerning operation.
- the brush will travel over one shoe edge and will then rotate through 180° so as to follow the opposite shoe edge.
- the device 47 Upon the brush passing close to the shoe toe, the device 47 will retract the locking device 46, in order to let the brush freely pass, said locking device being immediately afterwards positioned in place again.
- the carding head When work is over, the carding head will park in a position at which it does not interfere with the shoe and the work heads change of place relative to each other sliding along the respective horizontal guide rails.
- the cement-delivering nozzle By its own movement and the corresponding movement of carriage 12, the cement-delivering nozzle can therefore travel over its path along the shoe bottom as established, while keeping its outlet opening always tangent thereto.
- the actuators may be embodied either by electric, or pneumatic or hydraulic elements.
- the carding head may also be a traditional head provided with two rotating brushes, disposed on either side of the shoe to be processed.
