Definitions

  • This claim concerns an aided managerial procedure especially for the production of insulating glass (panels) that coordinates many work stations, called stations, and includes, for example only and without limiting the types and number of stations: one or more machines for cutting panes of glass, whether monolithic, laminated or armoured glass; one machine to form the spacer frame from a straight bar and obtain - by bending and/or calendering - a closed frame; a machine to fill the hollow part of the frame with hygroscopic material; a machine to apply the sealant to the sides of the spacer frame; a line (washing, assembly, sealing and so on) for the production of insulating glass.
  • One essential feature of the system is the special way (explained in detail in the description) to assist the operators who load and unload the machines.
  • the sequence of loading, unloading and moving the raw materials and the semi-finished products from one machine to the other (or from one station to another) is governed both by the common sense of the operators and by management programs that assist the operators in the work stations mainly by supplying them with printouts or, in the cutting lines, with an unfriendly monitor displaying only the division of the "origin" sheet of glass into the "destination" sections.
  • the “multiple glazing” is made of two or more “panes” (that is, sheets of glass), each pair separated by one or more hollow “spacer frame” with micro-holes on the internal side; the spacer frames being filled with hygroscopic material and the chambers created by the panes and the frames being filled with air or gas or gas mixtures that confer the "multiple glazing” particular properties, e.g. heat insulating and/or sound insulating.
  • the panes and frames are joined by two sealing operations, the first sealing makes the unit gas-tight (and is also useful for the production of the multiple glazing), the second operation binds the components and makes the assembly mechanically strong.
  • the "panes" used to produce the “multiple glazing” may be of different types according to the final use; for instance the eternal pane may be normal or reflecting (to reduce heat in summer) or laminated/armoured (to protect against trespassing/vandalism) or laminated/tempered (for safety reasons) or combined (for instance reflecting, and stratified to obtain a combination of features), the internal pane may be normal or low-emissivity (to reduce the dispersion of heat in winter) or stratified/tempered (for safety reasons) or combined (for instance low-emissivity and laminated to obtain a combination of features).
  • the “spacer frames” are made of hollow profiles that may be produced with different materials, thickness (corresponding to the distance between the panes), finishes and colours.
  • each producer of "multiple glazing” since it supplies many customers, organizes the jobs according to the lists of requirements of each customer, but it also groups and mixes the jobs in order to use the raw materials in the best way, mainly the sheets of glass (large panes, usually sized 6000 mm x 3210 mm, and of different types), the "spacer frames” (according to the materials, sizes, finishes and colours) and the sealants (usually polysulphide, polyurethane, silicone, hot melt, some two-components, other single-components, some available both as single and as two-components).
  • This process is carried out by means of management and optimization programs, for instance, for cutting glass.
  • the shipment units of the finished products must be reconstructed according to the destination, that is, the customer.
  • the operators are currently inadequately assisted, since they only receive printouts that list the "multiple glazing" for each customer and the components of the multiple glazing by uniform types, to deal with both as raw materials and as processing.
  • This invention intends to reduce the flow of information burdening the operators by communicating only the essential information in a synopsis and intelligent way.
  • a production line for "multiple glazing” (mainly rectangular, but also of other shapes) requires many cascading processes, and productivity and service to the customer may be improved if such processes, loading, unloading and moving of raw materials are rationalized, managed and assisted.
  • This invention concerns only the identification of the components of the insulating glass insofar as the same are marked - for instance - with bar codes, and each machine is equipped with a reader and the production is therefore managed, as well the production parameters of the machines are set according to the features (sizes, shapes, etc.) of the components being processed.
  • the main purpose of the object of this patent application is to solve the technical problems mentioned above and eliminate the drawbacks of the prior art mentioned above by means of an assisted coordination system for the production of "multiple glazing", that is, a system based mainly on a software program that assists the operators in loading and unloading the machines with raw materials or semi-finished products.
  • stations including, as a non-binding and non-limiting example concerning the number and types of stations: lines for cutting "panes of glass”; one machine to produce the spacer frame from a straight bar and obtain, by bending and/or calendaring, a closed frame; one machine to fill the hollow part of the frame with hygroscopic material; one machine to apply the sealant to the sides of the spacer frame and finally a line for the production of "multiple glazing" which itself is composed of several machines.
  • the essential feature of the aided managerial procedure is to use in each position where there is an operator, or at least in the most important positions, a monitor, or an equivalent device, that displays a 3D synopsis and dynamic view of the components while they are picked up from the other components of the same level during the feeding of a station or while they are accumulated with other components of the same level during the unloading of a station.
  • the operator is assisted because the component being processed is highlighted, in relation to the other components of the same level, by means of a different colour, by blinking. or by an arrow, etc.
  • the logic of progression of the components to be handled is always governed by the need of arranging the finished products in accordance with the progression required by the priorities of delivery of the finished product.
  • FIGURE 1 which concerns the "multiple glazing” product already described, displays the problems of differentiating the products to be laid on the carriages that come from the production grouped by types but assigned to different customers, each of them requiring a mix of types and dimensions.
  • This figures displays the edge of the "double glazing" in a non-limiting example of combinations: 1A normal, 1B triple glazing, 1C stepped panes, 1D laminated external pane and low-emissivity internal pane, 1E tempered reflecting external pane and low-emissivity stratified internal pane.
  • the two types of sealant used are also shown: in black, the butyl sealant for tightness (first sealing), in dotted lines, the sealant (polysulphide or polyurethane or silicone) required to achieve mechanical strength (second sealing).
  • the external/internal position is marked visually by the icons of the sun (external side) and of a heater (internal side).
  • FIGURES 2, 3, 4 show a possible version of the machines coordinated for the production of the insulating glass starting from the raw materials which are the “panes” to be cut, the "spacer frames", the sealants, up to the finished product, which is packed on the carriages or stands that will be subsequently, and almost in real time, shipped to the customer.
  • FIGURE 2 [VC] the vertical cutting table; [HC] the horizontal cutting table; in FIGURE 3: [PB] the automatic profile bender; [DF], the desiccant filler; [MB] the manual butyliser; [AB] the automatic butyliser; in FIGURE 4: [IL] the insulating glass line, the line for the production of insulating glass composed of the sections for edge finishing, washing, assembly, pressing, filling with gas, and sealing.
  • the monitor symbol and the letter [M] mark the positions where a monitor assists the view of the operator with a "3D, synopsis and dynamic", by blinking or in some other way highlighting the item to be picked up from the set of items or the position in the subsequent stage that the processed item is to be inserted.
  • FIGURES 5, 6, 7 (shaded, not due to a mistake made by the draftsman, but , as they concern the software part of the invention) better displays the interface with the operator.
  • FIGURE 5 displays the operating logic of the software part of the invention, as far as cutting of the "pane” is concerned, that is: in the first part, one can see a part of the storage of the glass panes ("origin"), for instance, a type of panes, where the well-known waste reduction program cuts them into the "destination" sizes; in the second part, one can see the operation of the software part of this invention that reorders the "origin" panes and, if this is not enough, re-runs the waste reduction programs, to organize the subsequent processes according to the priorities of delivery of the several types of multiple glazing to the final customers.
  • oil part of the storage of the glass panes
  • FIGURE 6 shows, for the part concerning cutting of the panes, the messages that the software part, which is an essential component of this invention, sends to the operator to assist him in handling each semi-finished product that comes out of the cutting table(s) and moving it to the correct carriage, and -within the carriage- to the correct position, so that in the subsequent processing station (in this case the washing machine of the insulating glass line) is fed with semi-finished products in the correct sequence according to the priorities of delivery of the several types of multiple glazing to the final customers.
  • the subsequent processing station in this case the washing machine of the insulating glass line
  • FIGURE 7 shows, for the part concerning the production of the "spacer frame", the messages that the software part, which is an essential component of this invention, sends to the operator to assist him in destining each semi-finished product that comes out of each machine that takes part in the production of the frame to the correct carriage so that in the subsequent processing station (in this case the coupling machine of the insulating glass line) is fed with semi-finished products in the correct sequence according to the priorities of delivery of the several types of multiple glazing to the final customers.
  • the software part which is an essential component of this invention
  • FIGURE 8 shows, for the part concerning the insulating glass line, the messages that the software part, which is an essential component of this invention, sends to the operators, at the feeding of the washing machine and at the delivery of the sealer respectively, to assist them in handling the semi-finished products ("panes") and the finished product (“multiple glazing”) according to the priorities of delivery of the several types of multiple glazing or in such a way as to optimize these priorities.
  • This invention may be realized in many variations (as compared to what can be seen in the drawings), all falling within the scope of the invention: which is, assisting the operator with a visual representation of the components to be fed and delivered in each stage of production, such variations may concern the methods of representation (orthogonal projections, 3D views, axonometric projections, perspective views, etc. the colours, the highlighting method), the positions of the monitors (external to the machine or on the machine itself, etc.), the quantity of monitors (as a function of the combinations of machines that carry out the process and of the extent of details to be supplied).
