- FIGURE 5 is a diagrammatic side elevational view of the autoclave apparatus and its associated equipment that is utilized in carrying out the process embodying this invention.
- this autoclave apparatus involves a cylindrical tank-type autoclave unit A that has a pivoted top 11 supported by the cylindrical tank member 10. Top 11 is hinged to tank as shown at 12 and the top is counterbalanced by the counterweight mechanism 13. Suitable bolt connector means 14 are utilized between the periphery of the hinged top 11 and the tank portion 10 to sealingly lock the top member 11 to the top of the tank member 10 during the several stages of the process to be hereinafter described. It will he noted from FIGURES 1-3 that the cylindrical tank 10 has interiorly disposed, chordal arranged, vertically extending partitions 16, 17, 18 and 19 that provide four vertically extending conduit chambers 21, 22, 23 and 24, respectively. These conduit chambers 21 through 24 are to facilitate the circulation of air and/or gas throughout the autoclave unit during the various stages of the laminating process as will be described hereafter.
- a base framework composed of a horizontally disposed bottom frame 28 and a horizontally disposed upper frame 29 that are interconnected by substantially vertically extending leg members 30.
- a funnel-shaped conduit 25 Extending between and mounted within the upper frame 29 and the lower frame 28 is a funnel-shaped conduit 25 that has a series of fluid circulating coils 47, 48 and 49 mounted in its center section 32.
- the upper section 31 of the funnel-shaped conduit 25 is provided with a trap door 31a for service purposes.
- the lower section 33 of the funnel-shaped conduit 25 terminates in an outlet 34 that provides the discharge into a centrifugal fan 50.
- Fan 50 is connected to a fan shaft 51 that mounts a pulley member 52 that is drivingly connected by means of belts 55 to a suitable motor driven pulley not shown.
- Drive shaft 51 is encircled by a seal 53, preferably of the 3,347,723 Patented Oct. 17, 1967 ice pressure responsive type.
- a suitable shaft bearing 54 journals the drive shaft 51.
- each of these coil units has an inlet pipe and an outlet pipe so that heating and/or cooling fluids of various types may be circulated through each of the coil units 47, 48 and 49.
- the coil 47 has inlet pipe 41 and outlet pipe 44.
- the coil unit 48 has inlet pipe 52 and outlet pipe 45.
- the coil unit 49 has inlet pipe 43 and outlet pipe 46.
- the supply riser 61 is connected to a main valve controlled manifold 69 that is adapted to receive either hot steam from the supply pipe 71 or some type of refrigerant or coolant from the supply pipe 70. Either of these fluids, namely a heating fluid or a cooling fluid, may be introduced into supply riser 61 through the manifold valve 69. Likewise, the fluid supplied through the riser 61 can be selectively introduced into the several coils 47, 48 and 49 by means of the valves 63, 64, 65.
- the coil supply and discharge risers 61 and 67 are also connected to the inlet and outlet respectively of the coil unit 66 that is mounted for the underside of the autoclave pivoted head 11.
- a fan unit 68 is positioned adjacent the coil 66 to facilitate heat transfer.
- conduit 78 Connected to the interior of the autoclave tank 10 is a conduit 78 such that compressed air or a similar pressurizing fluid medium may be introduced into the tank interior to facilitate the laminating process.
- the conduit 78 is connected through the tank sidewall 10 (see FIGURE 5) and this conduit is controlled by a valve 79.
- Conduit 78 is connected through valve 79 to a suitable pressure pump 80 that is adapted to be driven by a motor means 81.
- the first step is to assemble the materials to be laminated 83, 84 and 85 (see FIGURE 4) into laminating sandwich assemblies W.
- a deairing ring R which is an endless resilient ring, is applied around the entire periphery of each of the laminate assemblies W.
- the rings R are completely described in Harvey J. Little, United States Patents Nos. 3,074,466 and 3,074,838. Thereafter groups of these laminate assemblies W with the deairing ring R applied thereto are stacked in the baskets 35, 36, 37 and 38 as shown in FIGURES 1 and 3.
- the windshield laminate assemblies W with the deairing rings R mounted thereon are arranged in the stacked baskets 35-38 such that the windshield assemblies W in successive baskets are tilted in opposite directions. This facilitates a scrubbing action of the autoclave gases or fluids that are circulated across the windshield assemblies W during the laminating operation.
- the coupling of each ring R is connected to the header pipe 101 on each basket.
- Each basket header pipe 101 is connected to a riser pipe 102 when the several baskets 35-38 are stacked in the autoclave tank 10.
- a pressure of approximately 50 to 100 pounds per square inch is established within the autoclave unit A by means of the pressure pump 80.
- the heating medium introduced through the several coil elements 47, 48, 49 and 66 is such as to establish a temperature within the autoclave unit A of somewheres in the range of between 225 F. to 265 F. during the first stage of the laminating operation. With an evacuation pressure of to inches of mercury, a pressure of 50 to 100 pounds per square inch, and a temperature of 225 F.
- pretacking or prepressing of the laminate assemblies can be accomplished within a relatively short period oftime, that is within thirty minutes. While the temperature and pressure values given for this first stage of the laminating operation, that is called the prepress or pretack stage, have been found to establish a satisfactory prepress, it is notto be considered that the ranges indicated are the only ranges that will work. Changes in materials for the interlayer and outside sheets will undoubtedly require changes in the times, pressures and temperatures used in the laminating operation.
- the second stage of laminating or the final laminating stage is accomplished without removing the laminate assemblies W from the autoclave A.
- the second stage is achieved in the following mannerpFirst there is a termination of evacuation through the deairingrings R by connecting the evacuation conduit 104 to atmosphere through operation of the valve 74. At the same time that evacuation through the deairing rings is terminated, the
- the second or bonding stage of the lamination process can be accomplished within thirty-five minutes or less.
- the heated fluid supplied to the variouscoil units 47, 48, 49 and 66 is shut off by way of manifold valve 69.
- a coolant fluid may be introduced to the coils 47, 48, 49 and 66 by way of supply conduit 70, the manifold valve 69, and the supply riser pipe 61.
- This coolant fluid is then circulated through the various coil units 47, 48, 49 and so as to provide a fast but a controlled cooling within the autoclave unit A. Controlled cooling will prevent thermal shock that might cause glass cracking due to thermal stresses.
- the cooling of the'laminate assemblies also.
- temperature of the bonded laminate assemblies W can be dropped to less than 150 F. when the cooling stage disclosed is utilized.
- the pressure within the autoclave tank is relieved by suitable control of the pressure pump and the associated valve 79.
- the reason the pressure is reduced within the tank A during the cooling stage is that the heat transferfluid, that is the air or gas circulated within the tank by fans 50 and/or 68, is higher at the reduced pressure and thus it can be circulated faster.
- the evacuation or deairing rings R remain inactive during the cooling stage as .was the case during the second stage bonding or laminating stage. Obviously, if the laminate assemblies have been completely bonded during the second stage then there is no possible need for any deairing during the cooling stage because the glass sheets 83, 84 have already been bonded to the interlayer 85 through the area of the laminate assembly W.
- the circulating fans 50 and/or 68 for the heat transfer medium operate during all stages of the laminating process. While these fans can be constant speed units, still, it is possible to improve control of the. laminating process by using variablespeed fans that have thermostatic speed controls associated therewith. In this manner temperature sensors within the tank A can signal the interior temperatures to the fan speed controls and the fans. canoperate more effectively to maintain the desired temperatures during the variousv stages of the laminating process;
- One of the important conditions that must be maintained during a laminating operation to achieve maximum yield is that there bea uniform temperature and pressure laminating process in a minimum of time and with the minimum expense and operator supervision.
- the centrifugal fan 50 draws the air or otherheat transfer medium within the autoclave unit A downwardly through the lower end or outlet 34 of the funnel-shaped ducts 25. Air or gas drawn through duct 25 by fan 50 is discharged radially outwardly so that it tends to follow thepath of the arrows 110.
- the fluid flow path for the heat transfer fluid is relatively well defined by the several vertical chambers 21, 22, 23 and24 which carry the circulating heat transfer fluid from the lower end of the autoclave unit tank 10 upwardly along the tank side wall and discharges it across the top of basket 35 within the autocalve unit. The fluid flow from the top end of tank 10 will be downwardly through the several stacked baskets of laminate assemblies W from Where it will be discharged through the duct section 31 to the coil section 32 and then to the outlet section 33 and back into the fan 50.
- the supplemental heat transfer coil 66 and associated fan 68 that are mounted on the underside of the autoclave lid 11 can be omitted without materially interfering with the operation of the described two-stage laminating process, still, the units 66 and 68 insure maximum and uniform heat transfer within the autoclave unit A and therefore these units 66, 68 form a part of the preferred embodiment of this invention.
- FIGURE 1 Another arrangement of structure that is disclosed in FIGURE 1 and that contributes to the improved heat transfer achieved with this autoclave unit, is the specific arrangement of the windshield laminate assemblies W within the stacked baskets 35-38. By tilting the assemblies W in adjacent stacked baskets in opposite directions, it is possible to give the heat transfer fluid or gas circulated through the autoclave baskets a zig-zag path as indicated by the broken line 120 in FIGURE 1. This zig-zag path for the heat transfer fluid gives a scrubbing action to the fluid and accomplishes maximum heat transfer in minimum time.
- the baskets 35-38 that support the laminate assemblies W during the laminating process are substantially open frames of octagonal plan configuration. These baskets 35-38 have a pair of spaced bottom support bars 95 that are carried by an open peripheral frame 97.
- the bottom support bars mount rockable spacer bars 96 that keep the assemblies W spaced so that the heat transfer fluid passed vertically through baskets can pass freely across opposite sides of the assemblies W.
- the first step usually involved a prepress or tacking step using nipper rolls or the like, or some type of bagging operation carried on in a pressure chamber. Thereafter the individual prepressed laminate assemblies were then transferred to an autoclave unit for the second and final step of completing and curing the bond between the interlayer and the spaced outside sheets. Most frequently some type of handling of the laminate assemblies was required after the prepress step and before the final cure step.
- the autoclave apparatus with its novel circulation system for the air or gas, or other fluid that is used as the heat transfer medium, insures a uniform temperature throughout all parts of the autoclave tank and thus all laminate assemblies will be treated in the identical manner so that the yield of the process will be at maximum.
