Abstract

The present invention relates to the sector of leather manufacturing, mainly but not exclusively shoe manufacturing and relates to a process and apparatus for assembling a shoe or similar article, for example but not exclusively a so-called "pulling-over" or "lasting" machine, i.e. the machine in which the upper of a shoe is assembled on the form, under which the insole has previously been applied, in order to pull and glue the upper below the front part of the form.

Description

METHOD AND APPARATUS FOR MOUNTING A LEATHER ARTICLE SUCH AS A
SHOE
DESCRIPTION
Field of the invention
The present invention relates to the field of leather manufacturing, mainly but not exclusively shoe manufacturing, and relates in particular to a method and apparatus for mounting a shoe or similar article, for example but not exclusively a so-called pulling over, tacking or toe lasting machine, i.e. the machine in which the upper of a shoe is assembled on the shoe last, under which the insole has previously been applied, in order to pull and glue the upper, below the front part of the last.
Background of the invention
The aforesaid machines, for the functional purpose just mentioned, are provided with a mounting unit comprising a plurality of clamps arranged according to a curved path, adapted to pull on the periphery, and to centre with respect to the last, a blank of leather destined to form the upper, which will be then glued to the insole. Clearly, it is of maximum importance that such pull and particularly the centring action be performed with constant precision, i.e. with reliable and precise conformity with respect to the instructions programmed in the machine and based on a sample mounting.
Accordingly, despite the support provided by the programming of the machine, a manual intervention (or at least a check) by a trained operator is always necessary, to compensate for any differences between one piece and another (which in particular due to the use of natural materials may not have completely standardised characteristics), and any possible undesired movements of the upper blank in the initial step of the toe lasting process. Considering that even slight imprecisions can cause shoe assembly defects, and lead to waste, the importance that the aforesaid intervention has, in terms of production quality and economics, can be understood.
Therefore, highly specialised staff is needed, able to operate with the right attention and intensity required by modern productivity. On the other hand, to support the operator, various technologies have been introduced, including those that make use of the projection, onto the shoe being processed, of light reference marks that can guide the personnel, as well as digital technologies that have introduced imaging techniques with the comparison and superposition - on a display screen - between an image of the shoe acquired through one or more video cameras, and an image or reference template taken from records stored in a storage medium.
Summary of the invention
Although such techniques have promoted a significant improvement to working conditions and an increase in the production quality, the level of specialization of the trained operators being equal, the applicant has recognized the need for further proposals, particularly based on solutions that can maximise quality while preserving the margins of flexibility that are precluded to a completely automated system, solutions that therefore, although remaining within the context of a solid support and guide supplied by the machine, let the operator and his/her contribution of skills intervene to make a difference, especially in relation to a top quality shoe product.
However, in order to be fully successful, the development of a system of this kind must not require high structural complications and must provide the operator with a tool that is simultaneously intuitive and fully functional.
According to the present invention, a system has been successfully developed thanks to a method and apparatus for mounting a leather article such as a shoe with the essential characteristics according to the independent claims 1 and 9 appended hereto. Other significant and advantageous characteristics are defined by the secondary claims.
Brief description of the drawings
The characteristics and advantages of the method and apparatus for the mounting of a leather article such as a shoe according to the present invention will become apparent from the following description of an embodiment thereof, provided by way of non-limiting example with reference to the attached drawings wherein:
- Figure 1 is a schematic axonometric view of an apparatus according to the invention, in particular by way of example a toe lasting machine;
Figures 2 and 3 show enlarged parts of the apparatus of figure 1 , respectively at the region of a control touch screen, and of the mounting last unit with projection and video shooting system;
- Figure 4 is a block diagram that represents the structural and circuital architecture of the apparatus of the previous figures; and Figure 5 is a schematic representation of a device for projecting luminous reference marks, adopted in the apparatus of the previous figures.
Detailed description of the invention
With reference to the above figures, the invention shall be described below, without any limitative purpose, in an embodiment thereof implemented on a toe lasting apparatus, being it understood that the invention can equally be implemented on other apparatuses in the shoe making supply chain such as tack, peg, heel seat and side- lasting machines (terms that are familiar to a person skilled in the art), still by way of non limiting examples, considering that the invention is applicable also to machines dedicated to the production of leather articles other than shoes. The term“mounting” is used herein for the sake of conciseness and by way of example; it must indeed be interpreted in the broad sense to include any working step or sub-step on a shoe, and more generally on a leather article.
The apparatus in question is shown as a whole in Figure 1 , with a schematic depiction technique, fully justified by the fact that its general characteristics can be attributed to known apparatuses of which a person skilled in the art is fully aware. In relation to the present disclosure, it is sufficient to point out that a box-shaped frame 1 an assembling unit 2 can be noticed, having a curved array of clamps 21 adapted to enter into action on the leather intended to form the upper, according to working modes and sequences compliant with those already in use. The way the clamps are installed, their degrees of freedom, their activation program, and the related motorization and control systems and related accessories (supports, glue dispensers, motorized stretching plates, controls, etc.) are all - as such - outside the scope of the present invention, and can take on arrangements and features selected from the known ones; therefore, detailed depictions and descriptions of these elements are superfluous.
The assembling unit 2 is located within the visual field of at least one optical unit 3 which, as will become clear shortly hereafter, comprises photo/video acquisition means and projection means of luminous reference marks on the leather/upper being processed in the assembling unit 2. The machine further comprises at least one viewing screen (or display) 4 preferably of the touch screen type connected for data transmission with the optical unit 3, so as to enable the viewing of the images shot by the video acquisition means and to control the projective activity of the luminous mark projection means.
As depicted in figure 4, the display 4 is, in fact, controlled by an electronic control unit 5 (CPU with related storage medium) typically through an Ethernet communication line 6, a unit which in turn is connected to the optical unit 3 through a signal transmission line 7. A power supply block 8, adapted to be connected to a network power supply 81 , is connected both to the optical unit 3 and to the control unit 5. The display 4 can, in turn, make use of the power supply 41 from the service network, and be directly or indirectly in communication through a data exchange line 42 (also of the wireless type) with a local or global information network.
Software instructions are loaded onto the electronic control unit 5 to manage the operation of the apparatus as described below. Such instructions can be implemented, loaded and controlled according to techniques and languages that a person skilled in the art will recognise as purely instrumental and obvious to actuate by resorting to normal IT knowledge.
Returning more specifically to the optical unit 3, with specific reference to figure 5, besides to the aforesaid video acquisition means in the form of a normal video camera, it further comprises the projection means that in an advantageous embodiment envisage a device 31 comprising one or more mirrors 311 , 312 that when driven into rotation in a controlled manner by respective galvanometers 313, 314 deviate and direct to a desired target direction (i.e. onto the upper being processed) a coherent light beam Fs emitted by a source integrated into the unit (not shown). The mirrors, two in this case, hit the beam Fs in succession, and by moving them in a controlled manner a luminous spot will move, on the upper, as an effect of the upper itself being hit by the resulting output beam Fu. The arrangement of the two mirrors 311 , 312, or more precisely, of the related axes of rotation, is mutually orthogonal, such as to respectively control the movement of the output beam on a coordinate X and a coordinate Y of a Cartesian reference plane. In fact, Figure 5 shows various possible output beams Fu as a function of the respective displacements of the mirror.
By pushing the movement of the mirrors to high frequencies, the resulting movement of the light spot on the upper is perceived by the human eye as a continuous linear luminous mark Mp (figures 1 and 2). Appropriate optical elements (lenses, filters, etc.) can be used to increase or reduce the projection area as a function of the distance at which the optical unit 3 is positioned from the related target, i.e. the unit 1. Having established such position and distance, a system calibration can be performed (specific for every installation) such that the control software makes it possible to project the linear reference (or more generally the pattern of lines/marks) Mp exactly where required.
This latter functionality, according to an important aspect of the invention, is related with the display 4. In fact, it is precisely by“drawing” on the graphic interface display a reference mark, line or pattern (in practice, a“master” pattern Mm comprising vectorial geometries such as points, straight lines, curved lines, polygonal lines or a combination of such elements) in the desired position - clearly in relation to the image P acquired by the video camera and displayed on the same screen for a first sample being processed - that it will be possible to save the instructions for reliably and repeatably projecting the same“master” pattern in the same position on all the uppers being processed of the same batch, or however of subsequent batches with similar shape characteristics (line of the shoe). The mark, line or pattern will be typically and preferably drawn with the aid of a pen 42 (figure 3) but in general different modes or tools can be made use of. On the basis of the projected pattern of lines Mp, the operator will be provided with a univocal and direct reference on the part being processed, on which he/she can operate with manual modes and with the complete control of the actuation/drive of the assembling unit.
The aforesaid instructions shall typically assume the form of a configuration file, adapted to drive the galvanometers for the movement of the spot in the coordinates XY. Therefore, a library of master patterns/drawings will progressively be formed in the data storage of the apparatus, associated with respective individual models of shoe, that can be retrieved in the presence of the subsequent assembly of same or similar models (in that case the master images/instructions can also be edited, as necessary).
It will be appreciated that, thanks to the invention, the operator can be provided with a strong automatic help, still preserving the role of the human control, as thanks to the operator’s know-how he/she will be able to perform an analysis of the characteristic elements that he/she considers peculiar, making the relevant corrections and therefore enhancing all the elements functional to the success of the product assembly process. The intervention of the operator is materialised both in the master pattern Mm definition step (which, as has been mentioned, is generally free through a manual writing means), and even more so in the actual assembly/mounting step.
To summarize, the integrated system according to the invention includes and/or allows the following basic functions:
• Verification of the position and geometries of the product to be assembled/mounted;
• Extraction of significant punctual or linear geometries from the shoe for defining a reference pattern Mm to be converted into a luminous pattern Mp to be projected onto the shoe being processed;
• Control of the assembly operations with the aid of the luminous pattern, for example and in particular with verification of the alignment between the lines of the product and the projected luminous pattern Mp.
Among the accessory and optional functions the following can however be mentioned:
• generation of luminous reference marks in a specific position of the product, indicated by the actual operator regardless of, or in addition to, the projected pattern Mp;
• position correction of any projected luminous reference;
• saving not only of the patterns Mp generated, but also of the images P acquired by the video camera, advantageously with a mutual correlation;
• adoption of calibration matrices both for the system and for the detection of the product. With such activity, particular vectorial patterns can be created, which can be projected to assist the processing/reproduction of particular elements of the product;
• Interface for data exchange with company production management systems, in order to load product or order information, sending of production progress data and operating parameters in general.
In addition to the successful and synergistic combination aspect between automatic and manual prerogatives, the apparatus and process according to the invention offer the advantages of a tool that minimises direct contact with the mechanical parts (with the consequent favourable safety repercussions) and that allows the operator to perform the assembly operations of the product parts in a guided way without hindering the movements, facilitating the identification of the references and in general with simple, intuitive and functional operating methods.
The present invention has been described herein with reference to a preferred embodiment thereof. It is to be understood that there may be other embodiments that relate to the same inventive concept, within the scope of the appended claims.
