Definitions

  • the invention relates to a method and a system for the production of shoes which have a shaft, a shaft lining and a sole.
  • the object of the invention is therefore to provide a shoe, a method for its production and a system for carrying out the method, which at least largely allow automation and, insofar as manual intervention is required, the use of auxiliary personnel without reducing the quality of the footwear thus manufactured must be accepted.
  • this object is achieved by the design of the shoe according to claim 1, the design of the manufacturing method according to claim 3 and the manufacturing system according to claim 28.
  • the invention is based on the consideration that all manufacturing processes requiring expert skill are replaced by those that can be largely automated or carried out by technical assistants. However, this presupposes from the outset a departure from the conventional design concept that the lining to be provided in the shoe upper must be connected to the shaft blank from the outset in order to be able to carry out the shaping process for the finished shoe upper and the lining simultaneously. Rather, a shoe according to the invention is constructed from an outer shoe and a lining, the lining being produced separately from the outer shoe as an inner shoe and subsequently attached as a lining in the finished outer shoe.
  • the automatable method according to the invention already begins with the individual parts of the shoe models designed by a designer in computer design being graded by a shoe modeler on the computer and controlled very precisely by the computer from the raw material.
  • Cutting machines and tables of this type are known. Depending on the type of raw material used (leather, synthetic leather), it can be considered to work with laser or hot jet cutting machines.
  • the corresponding individual parts can be stored manually in magazines by assistants, from which they can be removed in a controlled manner by manipulators or robots and fed to an assembly line intended for carrying out the further production steps.
  • the lasting process in which the shaft blank is removed on the last is replaced by a shaping process in which the shaft blank is pressed against the last by means of pressure pads and appropriately shaped under the action of heat.
  • molded parts are used as reinforcements made of a thermoplastic plastic material for a shoe according to the invention, which are spatially deformed by the action of heat on the last from the previously flat or preformed state and thereby largely determine the shape of the outer shaft.
  • Such molded parts are, for example, front and heel caps and, if appropriate, molded parts on the lasting fold. You can also go through liquid or initially fluidly applied and then hardening or drying reinforcing materials are formed. The forming process does not require monitoring in its sequence. Rather, the outer shaft blank can simply be pulled onto the last and, after being set with regard to a marking on the last, temporarily fixed there. This is done by an assistant.
  • the last carries the required insole on its sole surface from the outset.
  • the last can automatically take this from a correspondingly provided work station of a production table or belt assigned to the last, by lowering the last, which can be raised and lowered with respect to the production table and can be adjusted clockwise along the production table, onto the insole, so that the sole surface with it comes into contact.
  • the holding of the insole on the last sole surface can be achieved in that holding pins are provided on the last sole surface, which penetrate the insole when placed on the insole and take it along when the last is raised again.
  • the molding and shaping of the outer shaft blank on the last takes place in such a way that the lasting flap is folded over the edge of the insole, so that after the shaping process this lasting flap points approximately towards the center of the sole surface.
  • This makes it possible, after the introduction of adhesive into the space between the insole and the lasting fold, to use a further lowering and pressing of the last on the production table to press and stick the lasting fold with the insole, the last acting as a pressure stamp.
  • the introduction of the adhesive into the space between the insole and the lasting fold can be controlled precisely and in time.
  • the last can be raised and lowered again for the purpose of connecting the outer shaft to a finished sole, which is located in a further work station of the production table and has been moved there in accordance with the step cycle.
  • the last is used at the same time to bring the finished formed outer shaft to the sole and as a pressure stamp in order to load the adhesive layer previously applied to the underside of the lasting fold and the insole and / or on the finished sole with the pressure required for the connection.
  • the last in addition to its shaping function, has the function of a feed device for holding and bringing together the individual parts making up the outer shoe and a connecting device in the form of a pressure stamp in order to connect these parts to one another. All of these functions can be controlled and monitored very precisely in terms of time and location by processors and can therefore be carried out automatically.
  • the last Since the last is intended for reshaping the outer shaft into which the lining produced as the inner shoe has to be subsequently introduced, the last has a shape which corresponds to the outer shape of the inner shoe.
  • the inner shoe is produced in an analogous process using an inner shoe last. The latter has a shape corresponding to the desired shape of the foot. As a result, the inner shoe is tightly received after insertion into the outer shoe and can be fixed in place as a lining by gluing.
  • the outer shaft blank before the outer shaft blank is mounted on a last, the outer shaft blank is connected to an insole by stroking. After shaping the shaft, it is connected to a shell sole, the shell edge of which covers the strobe seam. This takes the place of flipping a lasting fold around the edge of the insole in the In the course of the molding on the lasts, which requires a subsequent gluing of the lasting fold to the underside of the insole, the insole is connected to the outer shaft blank punched out without a lasting fold by stroking.
  • This process in which the insole is connected directly to the upper edge of the shaft by a loose seam, can easily be carried out on a strobe machine by an assistant.
  • the subsequent shaping process after the outer shaft blank thus created has been drawn onto the lasts is therefore limited to the shaping of the actual shaft with the shaft reinforcements.
  • the shell sole can also be designed as a finished sole, the shell edge overlapping the lower edge of the upper is glued to the upper.
  • mold the shell sole from a raw sole part made of vulcanizable material to the outer shaft in a vulcanizing mold or to injection-mold the initially flowable sole material in a known manner in an injection molding system.
  • Materials such as PU, PVC or TR (thermoplastic rubber) are suitable for this.
  • the system for carrying out the method according to the invention has a strobe machine in a work station in front of the last, in the working area of which the insoles are fed.
  • the individual parts making up the outer shaft and the inner shoe are automatically positioned very precisely relative to one another, the insole is picked up by the last, the shaping of the outer shaft blank on the last and the connection between the outer shaft and sole are carried out automatically, remaining intermediate actions, such as, for example, closing the outer shaft individual parts to form the spatially shaped outer shaft blank and pulling the outer shaft blank onto the last, can be done by trained persons Workers are carried out.
  • the productivity of shoe manufacturing can therefore be increased.
  • An essential feature of the invention for which protection is claimed regardless of the manufacturing method described, is to sell a separately manufactured lining separately from an outer shoe in the trade and to be able to interchangeably fit it in the outer shoe. In this way, used or sweaty lining can be replaced if the outer shoes are still perfect. This can play a role, especially with sports shoes.
