Definitions

  • the present invention relates to a machine for a shoemaking operation, especially for fixing the upper to the insole.
  • Known machines of this kind usually include support means on which to position a shoemaker's last to which is attached the insole and over which is laid the upper, means for gripping and stretching the upper, means for clamping the last on said support means, and means for folding the upper onto the insole in order to fix the upper to the insole.
  • GB-A-2 249 707 discloses an improved mechanisms for toe-lasting machine wherein heel press block and pressing means which press down on a toe portion of an upper are actuable simultaneously.
  • EP-A-0 269 333 discloses a system to perform operations on footwear upper assemblies, which includes a transfer mechanism to acquire a shoe upper assembly from a first shoe machine to a second shoe machine in a sequential operation, the upper assembly being reoriented and indexed automatically for operation thereon by the second machine.
  • EP-A-340 390 discloses a shoemaking set-up comprising, in particular, a first conveyor for removing a last from a conveyor for pallets, on each of which a last can be fixed, to a toe lasting machine and second transport device which, after removal from the last of the shoe shaft, toe lasting and heel and side lasting, removes by manual handling the toe-lasted, side-lasted and heel-lasted shoe unit from the heel and side lasting machine, places it positionally correctly on the pallet again and fixes it there.
  • the operator positions the last with the upper and the insole on the support means and then operates the machine in such a way that the grasping means grip and stretch the upper, the clamp means clamp the last on the support means, and the folding means fold the upper onto the insole, to which glue has been applied by suitable devices, so fixing the upper to the insole by adhesive bonding.
  • the last with the upper glued to the insole is released from the abovementioned grasping, clamping and folding means and drops into a suitable receptacle positioned near the support means.
  • the operator positions a new last with insole and upper on the support means and recommences the operating cycle. During this new operation the operator removes the previous last from the receptacle and passes it on for the succeeding operations. The process continues in this way, the lasts being used one after the other.
  • the operator may not remove the last from the receptacle during each new operating cycle, in which case the following last, on falling into the receptacle, may strike the previous last at some speed sufficient to cause damage to the uppers mounted on the lasts.
  • the machine for a shoemaking operation shown in Fig. 1, denoted as a whole by the numeral 10, is designed to adhesively bond the front part of the upper to the insole, thus carrying out one of the operations that lead to the finished item of footwear.
  • a last A is used to which the insole B is attached and over which the upper C is laid.
  • the machine 10 includes: a support 11 for the front part of the last A; a series of grips 12 controlled by actuators for gripping and stretching the upper C; a front pad 13 (illustrated in Fig. 1 only), a resilient front half collar 14 and a rear pad 15, all controlled by individual actuators and movable in the directions indicated by the arrows in order to clamp the last A on the support 11; and plates 16, also controlled by individual actuators, in order to fold the upper C onto the insole B.
  • the machine 10 also includes devices which apply the glue to the front part of the insole B, being arranged in the vicinity of the support 11, but not visible in the figures. These devices will not be further described as they are of known type.
  • a conveyor belt 17 connected to the support 11 by a sloping wall 18.
  • the conveyor belt 17 is driven by a motor 19 controlled by a central electronic control means 20, the last two items being shown in Fig. 1 only.
  • the machine 10 thus described and illustrated operates as follows.
  • the operator positions the last A with the insole B and the upper C on the support 11 and then operates the machine so that the grips 12 grip and stretch the upper C, the pads 13, 15 and the half collar 14 clamp the last A on the support 11, and the plates 16 fold the upper C onto the insole B to which glue has been applied by the appropriate devices, in such a way as adhesively to bond the upper C to the insole B.
  • the last A with the upper C bonded to the insole B is released from the grips 12, from the pads 13, 15, from the collar 14, and from the plates 16, and drops onto the sloping wall 18 where it slides under gravity down onto the conveyor belt 17, which then carries the used last A away from the machine 10 and on to the next operation.
  • the conveyor belt 17 can be connected at an angle to another conveyor belt 23 which likewise is provided both with lateral containment walls 24 and with a containment wall for the tail end, which wall is a continuation of the wall 21. In this way the used lasts are passed automatically to the location of the next operation.
  • Fig. 4 illustrates another conveyor belt 25 with lateral containment walls 26.
  • the connection between the conveyor belt 17 and the conveyor belt 25 is a "T" junction and the belt 25 is intended to collect the used lasts from a plurality of shoemaking machines such as the machine 10 working in parallel, and transferring them to the location of the next operation.
  • the central control means 20 may cause the motor 19 to drive the conveyor belt 17 continuously. Alternatively the central control means 20 may cause the motor, and hence the conveyor belt, to run intermittently, synchronizing them with the other movements of the machine. If the conveyor belt 17 is connected to another conveyor belt, as in Figs. 3, 4, the central control means may synchronize the movement of the conveyor belt 17 with the movement of the other conveyor belt too.
  • the machine 10 herein described and illustrated has many advantages which overcome the problems discussed in the introduction, owing to the fact that the operator is no longer required to pick up the already used last and move it so as to direct it towards the next operation, since this is done automatically.
  • the operator does not lose time in picking up and moving the used last, but simply gets ready to position the new last, thereby cutting out unproductive time and so increasing his productivity.
  • the sloping wall, the conveyor belt and the containment walls may be replaced by equivalent transferring and conveying means.
  • the conveyor belt in particular can be replaced with a functionally equivalent conveyor.
  • the path defined by the conveyor need not be straight but could, for example, be curved or otherwise shaped.
  • the machine can be provided with a robot that identifies, picks up and passes to the location of the next operation the lasts carried away by the conveyor belt.
  • the central control means will in this case synchronize the movement of the conveyor belt not only with the movements of the machine but also with the movements of the robot.
