Definitions
- the present invention regards the technical field of the machines for the footwear industry and relates to an apparatus for spraying glue and a process for bonding shoes.
- glue will be used to indicate any adhesive substance or mixture of substances usable to bond parts or components of a shoe.
- glue is sprayed along a path that defines the junction/overlay line between the sole and the upper.
- the bonding of shoe portions involves the use of spray glue dispensers which direct a glue jet on the portions of the footwear to be glued.
- the glue distribution needs to be performed with great precision and the higher is the quality of the footwear, the higher is the degree of precision required for gluing. In practice, high- quality footwear must be free from imperfections due to incorrect glue distribution.
- the bonding process is extremely simplified, accurate and effective; the productivity can be increased because the gluing speed is increased; it is possible to employ non-highly skilled operators, thanks to the operational simplicity of the apparatus; the apparatus keeps its characteristics unaltered even after prolonged periods of use; the apparatus is simple from a constructive point of view and requires limited maintenance.
- Fig. 1 is a schematic side view with parts in see-through of a possible embodiment of an apparatus according to the invention
- Fig. 2 is a schematic side view with parts in see-through of the embodiment shown in Fig. 1, in which the apparatus is represented in conjunction with a shoe being formed;
- Fig. 3 is an enlarged detail of Fig. 2;
- Fig. 4 is a front view of the apparatus in question
- Fig. 5 is a schematic lateral view of the apparatus, with portions removed according to the section line indicated by V-V in Fig. 4;
- Fig. 6 shows schematically a possible example of conformation of the distal part of a shielding element that is part of the apparatus in question.
- the present invention relates to an apparatus (1) for spray-dispensing glue on a shoe portion.
- the shoe portion (100) is the upper of a shoe to be manufactured.
- the apparatus (1) can be used to spray glue on the shoe portion (100).
- the apparatus (1) comprises a support structure (10) which is fixed to a plate (11), which is provided with connection and / or supply means (12) enabling it to be used in a unit for forming footwear.
- the structure (10) comprises a sliding stem (13) supporting a tool holder (14) on which the active components of the apparatus (1) are arranged as further disclosed below.
- the apparatus (1) comprises a first nozzle (2), that is supported by a
- nozzle (2) is capable of spraying a glue jet (20) towards the shoe portion (100) to be treated.
- nozzle (2) By appropriately moving the nozzle (2) with respect to the shoe portion (100), i.e. by turning the shoe portion (100) on itself or turning the structure (10) around the shoe in a known manner, the glue is distributed around the shoe along a path (101) extending along the peripheral development (edge) of the shoe portion.
- the nozzle (2) itself is of the known type and it is connected to a corresponding glue supply circuit not described in further details because it is also known in the art.
- the apparatus (1) comprises a shielding element (3) and at least one second nozzle (4).
- the shielding element (3) is supported by an arm (33) connected to the structure (10) so as to place the shielding element (3) in an area crossed by the glue jet (20) produced by the nozzle (2), the shielding element being positioned between the nozzle (2) and the portion of the footwear (100). As shown in Figs. 2 and 3, the shielding element (3) can be positioned close to the shoe portion (100).
- the shielding element (3) is capable of intercepting the glue jet (20) sprayed by the nozzle (2) to define a boundary line (30) for the glue distribution on said shoe (100).
- the shielding element (3) forms a barrier that intercepts the glue jet (20) leaving a shoe area free from the glue beyond the path marked with (101) in the drawings.
- the sprayed glue covers only the part (102) on which it is to be applied.
- said area free from glue is below line (101).
- the path (101) is predetermined by the shoe designer.
- the boundary line (30) is determined by the shielding element (3). In operation, the boundary line (30) overlaps the path (101).
- the apparatus (1) has an additional nozzle (4) which faces the shielding element (3) and directs a pressurized fluid jet (40) towards the same shielding element (3) to interact with any glue residues present there.
- a pressurized fluid jet (40) towards the same shielding element (3) to interact with any glue residues present there.
- the shielding element (3) is always cleaned by any residues and the bonding process can proceed without drawbacks due to the glue accumulations that after a certain period of use would limit the function of the shielding element.
- the additional nozzle (4) is preferably supplied with compressed air. For this reason the additional nozzle (4) is connected to a source (41) of compressed air.
- the second nozzle may increase the air pressure for predetermined periods of time.
- the nozzle (4) can emit very high pressure air jets, while maintaining a lower pressure in the other parts of the bonding cycle.
- Another feature of the invention is the structure of the shielding element (3), which is made and / or coated with a low friction material.
- the shielding element (3) can be coated, for example, with Teflon or any other low friction material, to interfere with the footwear material as little as possible.
- edges of the distal end (31) of the shielding element (3) can also be rounded to overcome any superficial irregularities presented by the shoe (100).
- the shielding element (3) can be concave, with the concavity facing the second nozzle (4).
- the jet of compressed air emitted by the nozzle (4) is indicated by (40) and the reference (40A) indicates the part which is diverted by the shield element (3).
- the apparatus (1) has one additional nozzle (4).
- embodiments of the invention may include a plurality of additional nozzles for directing multiple air flows towards the shielding element.
- the present invention also relates to a method for gluing a shoe portion by means of a sprayed glue.
- the method involves the use of a first nozzle (2) for spraying a glue jet (20) towards said shoe portion (100).
- the process involves screening the shoe portion by means of a shielding element (3) for intercepting said glue jet (20) and defining a glue line (30) for the glue distribution on said shoe (100), and to direct a pressurized fluid jet (40) towards said shielding element (3) by means of at least one additional nozzle (4) to interact with any glue residues present therein.
- the process may vary the pressure of the pressurized fluid (compressed air in the example) that forms the jet (40) emitted by the extra nozzle (4).
