Abstract
Description
- The present invention relates to a machine for manufacturing shoes and in particular to a machine for pulling over and lasting an upper on a corresponding shoe form.
- As is known, in the manufacture of shoes, the upper is glued to the insole. In order to achieve this, the upper is fitted and stretched over a form, to the bottom of which an insole has been applied beforehand. Then, after spreading glue around the contour of the insole, the edge portions of the upper are folded back and pressed against the insole.
- In accordance with the known art, the abovementioned operations are performed automatically using pulling-over machines. These machines comprise a support element for positioning of the shoe form thereon, pushing devices acting on the form in order to keep it in pressing contact against the support, a plurality of grippers for tensioning the upper, which are arranged around the support element, means for supplying glue along the contour of the insole, means for folding back the edges of the upper towards the underside of the form and means for pressing, from underneath, the edges of the upper folded against the insole.
- Machines of this type are known, for example, from the patents US-A 357691 and EP 0,118,243 B2.
- The use of machines which are able to perform the abovementioned operations automatically has proved to be advantageous both from the point of view of the high production volumes which these machines are able to achieve and owing to the uniform quality which these machines are able to ensure for the products obtained.
- The requirement which these machines must satisfy is that of managing to be adapted to the different dimensions and shapes of the existing insoles. In this connection it must be considered that, in the case of insoles of the same size, there may be models with different shapes and fits (for example narrow or wide fit).
- In order to achieve good gluing of the upper to the insole, it is necessary for the glue to be properly distributed around the contour of the insole. Therefore, it is obvious that, when there is a variation in the shape of the insole, the glue supplying means must be able to supply the glue at the required points.
- The need is therefore that of managing to provide glue supplying means which are able to be adapted to the different configurations of the existing inner soles.
- It must also be considered that supplying of the glue must be limited to only the portions of the insole which are intended to be glued to the upper, namely along the contour of the insole. In fact, the presence of glue outside of these portions is undesirable during the successive processing operations which the upper must undergo.
- In machines of the known art, the glue supplying means mainly consist of a supply plate provided with a plurality of nozzles arranged so as to be substantially positioned along the contour of the insole.
- However, these machines have the drawback that they cannot be adapted to insoles which have very different shapes and dimensions, except by means of replacement of the supply plate. Basically, these machines are provided with a plurality of interchangeable glue supply plates from among which it is necessary to choose the plate which is most suitable for the shape of the insole to be glued.
- In the patent EP 0,118,243 B2 the glue supplying means comprise a supply plate for supplying the glue in the region of the front portion of the insole and a movable nozzle for supplying the glue along the remaining part of the contour of the insole.
- In the patent it is also specified that the supply plate extends along the longitudinal axis of the insole over a distance of only 50 mm measured from the toe of the insole, so as to be suitable for most insoles.
This conclusion is based on the consideration that the front portion of the insole, namely the toe, remains substantially unchanged when there is change in the shape and dimension of the insole. - However, this is not exactly true. In order to illustrate this point, one need merely mention that there are shoes with square toes as opposed to shoes with rounded toes.
- The solution proposed in the patent EP 0,118,243 B2, therefore, does not overcome the above mentioned drawback, but only partially solves the problem. In other words, in order to be able to process insoles which are differently shaped, it is in any case necessary to use different types of interchangeable plates.
- The same limitation is present in US 3,422,474.
- To overcome this limitation EP 0,338,725 and EP 0,138,474 disclose an adhesive applicator mechanism, for supplying the glue in the region of the front portion of the insole, comprising a plurality of adhesive supplying elements articulated to each other so as to enable the configuration of the adhesive applying surface to be varied, according to the needs, by varying the relationship between the elements.
- In order to vary the relative position of the elements, adjustment threaded rods and complicated actuation devices, permanently coupled to the elements, are provided, which cannot be reconciled at all or easily reconciled with the requirement of leaving free space, without any encumbrance, for the movable nozzle or nozzles supplying the glue along the remaining part of the contour of the insole.
- In fact, the relative position of the elements not only is adjusted by the actuation devices, but is also held by the actuation devices, missing which, the relative position is subjected to possible changes, particularly in an operative environment with mechanical movements and consequent shocks and vibrations.
- A secure clamping in position of the elements cannot be provided by position adjusting threaded rods, as disclosed in D2.
- The problem underlying the present invention is that of devising a machine for manufacturing shoes which has structural and functional characteristics such that it is able to satisfy the above mentioned requirements and at the same time overcome the drawbacks associated with machines of the known art in simple way. This problem is solved by a machine for manufacturing shoes in accordance with Claim 1.
- Further characteristic features and advantages of the machine according to the present invention will emerge from the description below of a preferred example of embodiment thereof provided by way of a non-limiting example with reference to the accompanying figures, in which:
- Figure 1 shows a perspective schematic view of a machine according to the invention;
- Figure 2 shows a perspective view, on a larger scale, of a detail of the machine according to Figure 1;
- Figure 3 shows a perspective and exploded view of a detail according to Figure 2;
- Figures 4 and 5 show a schematic plan view of the detail according to Figure 3 in two different operating configurations;
- Figures 6, 7 and 8 show schematic views of a detail of the machine according to Figure 1 during different stages of the machine operating cycle; and
- Figure 9 shows a perspective view of a shoe form with upper and insole on which the position of the glue applied with the machine according to Figure 1 is shown.
- With reference to the accompanying figures, 1 denotes in its entirety a machine for pulling over and lasting an upper 21 on a
shoe form 2. Aninsole 23 is applied onto theunderside 15 of theform 2. - The machine 1 comprises a supporting frame 3 to which positioning means 5 intended to support the
form 2 in the region of thetoe 6 thereof are fixed. - In the example, the positioning means 5 consist of a
support element 4 with a flat triangular surface which extends over a small area and against which theform 2 is intended to be rested. - The
support element 4 is inclined so that the line Z perpendicular to its flat triangular surface substantially coincides with the line of vision of an operator who observes thesurface 5 itself, standing in front of the machine 1 (at the point indicated by "O" in Figure 1). - The machine 1 comprises an upper pushing device 7, two side pushing devices, both indicated by 8, and a
rear pushing device 9. These pushing devices are intended to engage respectively with theback 10, with thesides 11 and with theheel 12 of theform 2, so as to keep the form itself in pressing contact against the triangular surface of thesupport element 4, in an operative working position (Figures 6 to 8). - A plurality of grippers, which are all indicated by 13, are arranged around the
support element 4 so as to face the contour of thetoe 6 of theshoe form 2. In a manner conventional per se, thegrippers 13 are actuated so as to open and close and are individually displaced according to needs so as to achieve the desired tensioning of the upper 21 on theshoe form 2. - The machine 1 also comprises means which are indicated overall by 14, for folding back the edges of the upper 21 towards the
underside 15 of theshoe form 2, after opening of thegrippers 13, as well as means, indicated in their entirety by 16, for pressing from underneath the folded-back edges of the upper 21 against theinsole 23 along its contour provided withglue 24. - In the example shown, the
means 14 for folding back the edges of the upper 21 comprise twocurved plates 17 reproducing the profile of the contour of thetoe 6 of theshoe form 2 and movable towards the form itself. Themeans 16 comprise a plurality of rod-shaped elements 18 which are movable (in a transverse direction Y-Y) towards theform 2 so as to engage with it, from underneath, with a predetermined elastic force. - The machine 1 comprises means for supplying the glue along the
contour 27 of theinsole 23 associated with theunderside 15. - These means comprise a
supply plate 19 positioned in the vicinity of thesupport element 4 and twonozzles 23 for supplying the glue, which are movable so as to be able to follow thecontour 27 of theinsole 23. - The
supply plate 19, which according to a preferred example of embodiment is in the form of a horseshoe (Fig. 5), is positioned around thesupport element 4 and comprises a plurality of fixed supply nozzles indicated by 20 in the figure. - By means of actuating means conventional per se and not shown in the Figures, such as for example hydraulic actuators, the
plate 19 is movable in the direction of the axis Z-Z indicated in Figure 1 from a rest position at a distance from the form 2 (Fig. 6) to an active position (Figs. 7 and 8) where it engages from underneath with the shoe form 2 (more precisely with theinsole 23 applied to the underside 15) so as to distribute theglue 24 along thecontour 27 of theinsole 23 by means of thesupply nozzles 20. - In the light of what has been described above, it is-obvious that the
plate 19 allows theglue 24 to be supplied along thecontour 27 of the front portion of theinsole 23, namely in the region of thetoe 6 of theshoe form 2. - The
supply plate 19 comprises a plurality ofsegments plate 19 is therefore articulated so as to be able to adapt its shape to the shape of thecontour 27 of theinsole 23. In the example shown in the Figure, theplate 13 comprises foursegments pins 26 which are three in number (26A,26b,26c)in the example. For this purpose, the ends of thesegment pins 26. - According to the invention, the
supply plate 19 is associated with anunderlying support plate 28 so as to be able to be hingeably connected wit respect thereto. - The
intermediate pin 26A in the chain is steadily positioned on thesupport plate 28 along the axis of symmetry (or centre line) X-X of thesupport plate 28, namely at the toe end of theshoe form 2, while the other twopins support plate 28, are positioned so as to be located on opposite sides with respect to the above mentioned axis of symmetry. - By hingeably adjusting the
segments 19a of theplate 19 about the hingingpin 26A and thesegments 19b about the hingingpins plate 19 to that of thedifferent insoles 23. With reference to Figures 4 and 5, theplate 19 is shown in the narrow and widened configurations, respectively. - The
supply plate 19 and thesupport plate 28, besides being connected by thepin 26A, are connected by means of twofixing elements 31 which allow thesegments 19b of thesupply plate 19, remote frompin 26A to be steadily fixed and locked in the desired position with respect to thesupport plate 28. Preferably, the fixingelements 31 comprisescrews 29, the shanks of which are inserted intorespective eyelets 30 in thesegments 19b of theplate 19. - The size of the head of the
screws 29 is greater than the size of theeyelets 30. The shanks of thescrews 29 are also inserted into respective elongated eyelets orslots 32 of thesupport plate 28. The end portions of thescrews 29 emerging from theeyelets 32 are provided with a fixing nut 25 (Fig.3). Until thescrews 29 are fully tightened, the screws themselves are able to move in theeyelets 32 and consequently it is possible to vary the position of thesegments support plate 28. - On the other hand, when the
screws 29 are tightened, the heads thereof lock thesegments 19b against thesupport plate 29, preventing any further displacement of bothsegments - The above mentioned actuating means which move the
plate 19 from the rest position at a distance from the form 2 (Fig. 6) to the active position (Figs. 6 and 7) act on thesupply plate 19 by means of thesupport plate 28. - The glue supplying means of the machine 1 further comprise two nozzles for supplying the glue, indicated by 22. The
nozzles 22 are movable, namely are supported by the frame 3 of the machine 1 so as to be able to follow the portion of thecontour 27 of theinsole 23 which is not affected by thesupply plate 19. In particular, with thenozzles 22 it is possible to follow and therefore supply theglue 24 along the opposite sides of theinsole 23. - The machine 1 comprises actuating means which are known per se and not shown in the Figures, for example hydraulic actuators, which allow the
nozzles 22 to be actuated so that they move along thecontour 27 of the insole starting from theplate 19, namely in the zone which is not affected by thesupply plate 19. The machine 1 comprises operating and control means, not shown in the Figures, for managing operation of the actuating means. In particular, during each operating cycle of the machine 1, these operating and control means allow thenozzles 22 to be positioned along thecontour 27 of theinsole 23 and behind theplate 19, also when there is a variation in the shape of theplate 19. Therefore, the abovementioned operating and control means allow the movement and the displacements of thenozzles 22 to be varied according to the type ofinsole 23. For this purpose, the operating and control means comprise a memory, such as for example an EEPROM, in which it is possible to store different programs for movement of thenozzles 22. - Preferably, the
nozzles 22 terminate in a roller which allows distribution of theglue 24 supplied along thecontour 27 of theinsole 23. - Electric resistances, which allow the glue to be heated so as to render it more fluid, are associated with the
supply plate 19 and thenozzles 22. - The nozzles of the
supply plate 19 and themovable nozzles 22 are in fluid communication with a glue storage tank (not shown in the figures). - During operation of the machine 1, the
shoe form 2 is placed against thesupport element 4. Then the pushingdevices form 2 in its working position (Figures 6, 7 and 8). Tensioning of the upper 21 is performed on theform 2 by means of thegrippers 13. - At this point, displacement of the
supply plate 19 is effected from the rest position (Fig. 6) to the active position (Figs. 7 and 8) where the glue is supplied via thenozzles 20. Theglue 24 is therefore applied and distributed along the front portion of thecontour 27 of theinsole 23. Once supplying of theglue 24 has been performed, thesupply plate 19 is brought back into the rest position. - At the same time, the
nozzles 22 are actuated so that they come into contact with thecontour 27 of theinsole 23, in the vicinity of the supply plate 19 (Fig. 7). Then thenozzles 22 are actuated so that they follow thecontour 27 of the insole 22 (until they reach the position illustrated in Figure 8) so as to supply and apply theglue 24 thereon. - It should be emphasised that the point along the
contour 27 of theinsole 23 from where thenozzles 22 start to supply the glue depends on the configuration of theplate 19 or more precisely on thesegments 19a of thereof. Basically, thenozzles 22 are positioned so as to start from behind theplate 19. - After the
glue 24 has been applied to thecontour 27 of theinsole 23, themeans 14 are first actuated so as to fold back the edges of the upper 21 towards the insole and, then, subsequently, also themeans 16 are actuated so as to press from underneath the edges themselves against theinsole 23, thereby ensuring that the upper 21 is glued to theinsole 23. - With regard to that described above, it is obvious that the configuration assumed by the
supply plate 19, or rather by thesegments insole 23, without having to change thesupply plate 19. Thus, for example, it is possible to hingeably adjust the segments of thesupply plate 19 so as to make them suitable for the inner soles of shoes with a square or rounded toe. Thenozzles 22 are also able to apply perfectly theglue 24 along thecontour 27 of insoles which have different shapes. - It is obvious that, in the case where the machine is provided with the means for hingeably arranging the supply plate and with the control and adjusting means described above, the operation of hingeably adjusting the
plate 19 so as to adapt it to the shape of aninsole 23 may be advantageously performed automatically rather than manually. - As can be appreciated from that described above, the machine for manufacturing shoes according to the invention is able to satisfy the requirements referred to in the introductory part of the present description and at the same time overcome the drawbacks associated with the machines of the known art.
- In fact, the machine for manufacturing shoes according to the invention is able to perform gluing of the upper to insoles of various dimensions and with different shapes without having to replace any parts.
- Another advantage of the machine for manufacturing shoes according to the invention lies in the fact that operation thereof may be completely automated.
