Definitions

  • This invention relates to a machine for lasting the edges of the sides of an upper on a last in accordance with the precharacterising clause of claim 1.
  • this invention relates to an upper-lasting and heel-lasting machine, that is a machine capable of stretching and bonding the edges of an upper and the heel on a last with the sole-piece of which an insole has first been associated.
  • edges of the upper and the heel are generally fixed to an insole by adhesive bonding.
  • the aforesaid edges must first be folded onto the sole-piece of the last and then stretched or pressed on this after a layer of adhesive has been applied.
  • immobilizing means known in the jargon as " hands”
  • a plurality of stretching means known in the jargon as " fingers "
  • the stretching means perform a movement having a transverse movement component with respect to the last so as to turn and press the edges of the sides of the upper onto the insole associated with the sole-piece of the last.
  • upper- and heel-lasting machines are provided with two opposite working units, each provided with their own stretching means, which work in such a way as to move the corresponding stretching means and cause them to approach each other up to a predetermined centreline.
  • the technical problem underlying this invention is therefore that of devising a machine for lasting the edges of the sides of upper to a last which has structural and functional characteristics such as to satisfy the requirement of being also suitable for footwear having marked asymmetry in the shape of the insole because of a marked indentation present on the inside of the insole, at the same time overcoming the disadvantages mentioned in respect of the known art.
  • this invention also relates to a method for lasting the sides of an upper on a last in accordance with claim 8.
  • the appended figures illustrate some parts of a machine according to the invention for lasting the edges of the sides of an upper on a last, that is a so-called upper-lasting machine.
  • the machine comprises:
  • supporting means 1 make it possible to support last A in the overturned position, that is in such a way that the sole-piece of last A and insole B associated therewith face upwards, as illustrated in Figure 1.
  • These supporting means 1 comprise a block (partly visible in Figure 1) to support the toe of last A and a rear support (visible for example in Figure 2) which can be adjusted for height in a vertical axis Z-Z.
  • insole B which is designed to come into contact with the folded over edges of the upper C, that is the one facing upwards and visible in Figure 1, is designed to receive a layer of adhesive delivered from aforesaid adhesive delivery means 6.
  • adhesive delivery means 6 are positioned substantially above supporting means 1 and comprise one or more delivery nozzles 7, in the example two.
  • Nozzles 7 are supported by a mount 8, which can move in the direction of the aforesaid axis of symmetry X-X, with respect to which nozzles 7 can in turn move transversely.
  • Activating means which are in themselves known then control the movement of nozzles 7 and mount 8 so that nozzles 7 follow the perimeter of the edge of insole B along posterior part 4 and the sides 5 thereof as the adhesive is being delivered.
  • Adhesive delivery means 6 may be replaced by any equivalent means.
  • the aforesaid adhesive delivery means may be directly replaced by means for delivering hot air to the pre-glued part so as to render the adhesive present functional.
  • Immobilizing means 9 for last A and upper C fitted thereto in the example comprise a deformable strip 2 which is substantially U-shaped.
  • Deformable strip 2 is positioned in such a way that it can grasp the rear part of last A, known in the jargon as the heel, and a predominant portion of its sides when the last is positioned on supporting means 1.
  • deformable strip 2 is positioned lower in height than stretching means 3 so as not to interfere therewith when they make their working movement.
  • Opposing pressing means 14 activated by corresponding actuator means 15 act on deformable strip 2 in order to cause it to lock against the upper C lasting last A with a preset load.
  • deformable strip 2 is only shown in Figure 1, while pressing means 14 and corresponding actuator means 15 are only shown in Figures 2 to 7.
  • Pressing means 14 known in the jargon as hands, comprise an elastic block mounted at the travel end of the rod of a pneumatic piston acting as actuator means 15 which travels in transverse direction Y-Y.
  • pressing means 14 are positioned in such a way that they can act on two opposing open limbs of the U provided by deformable strip 2.
  • Aforesaid actuator means 15 are supported by a supporting structure 10 of the machine.
  • the machine according to the invention comprises two separate working units 16, 17, each comprising corresponding stretching means 3 and corresponding first actuator means 11.
  • the two working units 16 and 17 are positioned in such a way as to face each other on opposite sides with respect to centreline X-X. In fact the two working units 16 and 17 form between them a working space within which last A is located, supported by supporting means 1.
  • each working unit 16, 17 are located in such a way that during the working stage their lower surfaces are substantially coplanar with insole B, so that the edges of the upper C can easily be folded thereupon.
  • Stretching means 3 apply a plurality of mechanical fingers 3a extending in the transverse Y-Y direction and located adjacent to each other in the direction of centreline X-X. Fingers 3a are designed to shape the lateral edges of the upper C onto the corresponding lateral profiles 5 of last A. Each mechanical finger 3a is supported at the extremity of a supporting frame 3b against which first actuator means 11 act.
  • first actuator means 11 comprise a plurality of lower pneumatic pistons 11a orientated in the transverse Y-Y direction and located adjacent to each other in the direction of centreline X-X, and a plurality of upper pneumatic pistons 11b above orientated in the transverse Y-Y direction and located adjacent to each other along the direction of centreline X-X.
  • Each pneumatic piston 11a, 11b has a corresponding rod whose free end faces last A.
  • Each supporting frame 3b is associated with the rod of a lower pneumatic piston 11a and the rod of a corresponding upper pneumatic piston 11b. More particularly supporting frame 3a is hinged at the free travel end of the rod from corresponding lower pneumatic piston 11a in such a way that it can rotate with respect to the said extremity about an axis parallel to the aforesaid centreline X-X. Furthermore the free end of the rod of the corresponding upper pneumatic piston 11b interferes with supporting frame 3a during its travel towards last A.
  • supporting frame 3b is forced to follow the rod of pneumatic piston 11a in its back-and-forth movement, causing corresponding mechanical finger 3a to carry out its working movement stretching the upper C onto insole B.
  • upper pneumatic piston 11b is activated bringing about rotation of supporting frame 3c about its hinging point causing said mechanical finger 3a to press stretched the upper C onto insole B with a preset load.
  • stretching means 3 and corresponding first actuator means 11 are supported by a moving structure 12 which is supported by support structure 10 through intermediate second actuator means 13 capable of controlling the movement of the entire moving structure from a position distant from centreline X-X to a position close to it so as to ensure a plurality of forward travel end positions for stretching means 3 with respect to centreline X-X.
  • the forward travel end position of stretching means 3 can be varied with respect to centreline X-X.
  • both the abovementioned working units 16, 17 are supported by a corresponding moving structure 12 which is itself supported by supporting structure 10 through intermediate second actuator means 13 acting to control the movement of the entire moving structure from the position at a distance from centreline X-X to a forward position with respect to it.
  • second actuator means 13 associated with a working unit 16, 17 each comprise at least two actuators arranged in series with each other and selectively activatable so as to bring about:
  • the aforesaid base starting position is determined for each of aforesaid working units 16, 17 in such a way that corresponding stretching means 3 substantially lie along centreline X-X when they are in their forward travel end positions as illustrated in Figures 2 and 3.
  • the arrangement of the two actuators in series makes it possible to use the back-and-forth movement of one of the two actuators to bring about the reversible movement of moving structure 12 of a working unit towards centreline X-X and to use the back-and-forth movement of the other actuator to bring about reversible movement of moving structure 12 of the same working unit away from centreline X-X.
  • second actuator means 13 associated with a working unit 16, 17 comprise a first and a second pneumatic cylinder placed one above the other, a lower one 13a and an upper one 13b respectively, connected together in such a way that they are operatively associated in the serial manner described above.
  • the two pneumatic pistons 13a and 13b are rigidly connected together and are orientated in such a way that their corresponding rods are orientated in transverse direction Y-Y. More particularly, while one piston (in the example upper piston 13b) has its corresponding rod orientated towards moving structure 12 and attached thereto, the other piston (in the example upper piston 13b) has its corresponding rod orientated in the opposite way connected to supporting structure 10 of the machine.
  • the machine according to the invention comprises command and control means, pneumatic circuits and other components necessary to ensure its proper operation, which being of a type in themselves known will not be described in detail.
  • Figure 1 illustrates a condition in which last A on which the upper C is stretched and with the foot of which insole B is associated has just been positioned on supporting means 1 and the working cycle of the machine has yet to begin.
  • insole B has slight asymmetry between the inside and outside, in such a way that stretching means 3 of the two opposing working units 16, 17 can work in a substantially symmetrical way without any problems arising.
  • the working movement of stretching means 3 brought about by corresponding lower pneumatic piston 11a and upper pneumatic piston 11b takes place in such a way that mechanical fingers 3a substantially reach centreline X-X in their forward travel end position, as illustrated in Figures 2 and 3.
  • Figures 4 and 5 relate to the situation of an insole having marked asymmetry between the inside and the outside for a right shoe.
  • the working cycle of the machine corresponds to the former cycle, except for the fact that the working movement of stretching means 3 described above is preceded by a stage in which second actuator means 13 are acted upon to vary the base starting position of the two working units 16, 17.
  • the base starting position of working unit 16, that is the working unit on the inside of insole C, which has a marked indentation is brought forward by a predetermined distance H towards centreline X-X, while the base starting position of the other working unit 17 is moved away from that centreline by the same distance.
  • the aforesaid movements are controlled by actuating only lower pneumatic piston 13a of actuator means 13 associated with working unit 16 and upper pneumatic piston 13b of actuator means 13 associated with working unit 17.
  • Figures 6 and 7 relate to the mirror-image situation to that in Figures 4 and 5, that is the situation for an insole having marked symmetry between the inside and the outside in the case of a left shoe.
  • the machine for lasting the edges of the sides of an upper to a last makes it possible to satisfy the aforesaid requirement and at the same time to overcome the disadvantages mentioned with respect to the known art in the introduction to this description.
  • the presence of the second actuator means as a connecting member between the supporting structure of the machine and the working units makes it possible to overcome the problems associated with the great asymmetries between the inside and outside of insoles of different items of footwear simply and quickly.
  • the machine according to the invention is also capable of perfectly suiting insoles having the aforesaid great asymmetry as well as more symmetrical insoles.
  • Another advantage of the machine for lasting the edges of the sides of an upper to a last according to this invention lies in the possibility of it being simple to construct and easy to operate. In this respect it is worthwhile pointing out that it is possible to compensate for greater or lesser asymmetries depending upon the type of actuators used, in particular the lengths of the rods of the pneumatic pistons.
  • Yet another advantage of the machine according to this invention lies in the possibility of manufacturing footwear having insoles with marked asymmetry or footwear having more symmetrical insoles in sequence without having to replace parts of the machine.
  • the actuator means may differ from those considered above.
  • the use of hydraulic actuators is also a possibility.
