JNL No...OT
applying the backing sheet over the outer sheet and liquid foam reactants and inserting spacers there-between;
heating the sheets and foam reactants in an oven to expand the foam reactants and form a continuous panel;
removing the spacers; and cutting the panel to a desired length.
In one particularly preferred embodiment of the invention, there are at least two coil stations for receiving backing sheet coils and at least two coil stations for receiving outer sheet coils and the method includes the step of leading a sheet from a following coil for jointing with sheet from a leading coil to provide a substantially continuous course of backing sheet and outer sheet.
Preferably in this case, one of the backing sheet coil stations has an associated bypass conveyor to the lower outer sheet conveyor and the method includes the steps of fitting an outer sheet coil to the backing sheet coil station and leading the outer sheet from the coil along the bypass conveyor to the lower outer sheet conveyor.
In one preferred embodiment of the invention, there are two backing sheet coil stations and two outer sheet coil stations, one of the backing sheet coil stations having a bypass conveyor for leading an outer sheet coil located at that coil station to the outer sheet conveyor.
In another embodiment of the invention, the method includes the steps of overlapping the end of an outer sheet from one coil with the start of an outer sheet from
another coil, sensing the overlap and automatically attaching the outer sheets at the overlap to form a joint. In this case, the outer sheets are overlapped for a distance of at least 250 mm and the outer sheets are attached by applying a number of spaced-apart rows of connections between the sheets at the overlap.
Preferably each connection is formed by punching a hole through the outer sheets at the overlap and swaging the hole thus formed.
In a further embodiment of the invention, the method includes the step of applying a release material to the lowermost face of the outer sheet. In this case, preferably the release material is a strip of plastics material which is continuously applied from a supply reel to the lowermost face of the outer sheet as it travels along the outer sheet conveyor after profiling.
In another embodiment of the invention, the panel has a projecting part formed along one longitudinal side edge thereof and a complementary receiving part including a recess for the projecting part formed along the other longitudinal side edge thereof and the method includes the steps, after heating in the oven and before cutting of automatically and continuously inserting an edge joint sealing member into the recess.
Preferably prior to insertion of the edge sealing member, of continuously applying adhesive into the recess to receive the edge sealing member and, on insertion of the edge sealing member, applying the edge sealing member to the adhesive.
In a preferred arrangement, the edge sealing member is automatically inserted into the recess at a speed and tension proportionate to the speed of travel of the panel.
- 4 In this case, the adhesive is preferably applied proportionally to the speed of travel of the panel to apply a substantially even spread of adhesive in the recess along the length of the panel.
In a further embodiment of the invention, the method includes the step of palletising the finished cut panels.
In this case, preferably a pallet to receive a cut length of panel and/or a stack of panels to receive another panel is available on demand at the palletising station.
In a further embodiment of the invention, the method includes the step of releasably mounting a train of spacer blocks on an endless chain, and, as required, removing a first set of spacer blocks associated with one panel from the chain and mounting another set of blocks associated with another panel on the chain.
The invention also provides an insulating panel whenever manufactured by a method as claimed in any preceding claim.
The invention will be more clearly understood from the following description thereof given by way of example only with reference to the accompanying drawings, in which :Fig. 1 is a diagrammatic flow chart of a method 5 for manufacturing an insulating panel according to the invention;

- 6 Fig. 10 is an elevational partially crosssectional view of part of the apparatus of Figs. 7 to 9.
Referring to the drawings and initially to Figs. 1 to 4 thereof, there is illustrated a method for manufacturing an insulating panel. One example of an insulating panel which may be manufactured by the method of the invention is illustrated in Figs. 2 to 4 and comprises a profiled steel backing sheet 2 and a profiled external outer metal sheet 3. An insulating core 4 of polyurethane material is provided between the backing sheet 2 and outer sheet 3. It will be noted that in this case the insulating panel includes a projecting part 6 at one longitudinal side edge thereof and a mating recess part 7 at the other longitudinal side edge thereof for mating engagement between the panels on assembly in use as illustrated in Figs. 3 and 4. In this case, an edge sealing member 9 of elastomeric material is provided in the recess 7 for a sealing engagement on assembly with the projecting part 6 of an adjacent insulating panel.
Referring particularly to Fig. 1 in the method for manufacturing an insulating panel according to the invention, a backing sheet 12 is led from one of two coil stations 13,14. A top or outer sheet 15 is led from one of two top sheet coil stations 16,17 or, as explained in more detail below from the second backing tray coil station 14. The backing sheet 12 is led from the coils 13,14 to an upper conveyor 20. A joint between the end of a backing sheet from one coil and the start of the next coil is made on the upper conveyor 20 by advancing the backing sheet 12 from a following coil until it is aligned with the end of the backing sheet from the leading coil. Jointing tape is then applied in step 21 across the joint between the end of the leading coil and the leading edge of the following coil to provide a substantially continuous supply of backing sheet to the manufacturing process. The backing sheet on the top conveyor is then profiled in step 22 to provide a desired outer profile and then preheated in step 23.
The outer sheet 15 is led along a bottom conveyor 21 from one of the coil stations 14,16,17 as will be described in more detail below at the end of a coil of outer sheet material. The start of a following coil is advanced so that the leading edge of the following coil is overlapped with the trailing edge of the first coil. A reflective tape is applied in step 26 at the overlap joint and the overlap joint is advanced along a bottom conveyor 24. At a jointing station 27, the presence of the reflective tape applied in step 26 is automatically sensed and a number of spaced-apart rows of connections are made between the outer sheets 15 at the overlap. The overlap is for a distance of at least 250 mm and each connection is in this case formed by punching a hole through both outer sheets 15 at the overlap and swaging the hole thus formed. A number of rows of such connections are provided across the overlap for secure fixing of a leading outer sheet to a following outer sheet to provide a substantially continuous course of outer sheet to the manufacturing process .
In step 29, a release material in the form of a strip of plastics material is applied to the underside (i.e. the lowermost face) of the outer sheet 15. The plastic strip is continuously applied from a supply reel to the underside of the top sheet 15 as it travels along the outer sheet conveyor 24.
In step 28, the outer sheet 15 is profiled as required.
In step 30, the profiled outer sheet 15 is preheated.
The preheating of the outer sheet 15 and backing sheet 12 is carried out by leading the outer and backing sheets 15,12 through a common preheater unit. When the outer sheet 15 exits from the preheater unit 30 in step 35, side adhesive tapes are applied to both longitudinal side edges of the profiled outer sheet 15. The profiled outer sheet 15 is then subjected to a localised heating in step 36 typically by applying infra-red heat to the uppermost face of the outer sheet to present the outer sheet 15 at an optimum temperature to a station 37 at which liquid foam reactants are laid down on the uppermost face of the outer sheet across the outer sheet 15 between the side tapes. The side tapes prevent spillage of the liquid foam reactants during lay-down and in further processing. The preheated backing sheet 12 is then applied over the outer sheet 15 with the side tapes and liquid foam reactants applied in step 40. Side spacer blocks are then applied at the longitudinal side edges of the panel between the outer sheet 15 and backing sheet 12 in step 41. The backing sheet 12, outer sheet 15 with the side tapes and liquid foam reactants therebetween and the side blocks spacing the sheets 12,15 apart are then passed through an oven in step 42 in which the liquid foam reactants expand to form an insulating core between the backing sheet 12 and outer sheet 15.
As will be described in more detail below, in step 45, an edge seal 9 is applied to one longitudinal side edge of the panel thus formed. The panel is then automatically cut to a desired size on line in step 46. If required, the transverse cut edge of the panel is hand finished in step 47 and then stacked and palletised in step 48.
Referring particularly to Figs. 5 and 6, it will be noted that in this case, there are two coil stations 13,14 for receiving backing sheet coils and two coil stations 16,17 for receiving outer sheet coils. The backing sheet coil station 14 is provided with a bypass conveyor 50 for delivery of sheet material from the station 14 to the bottom conveyor 24. In this way, the second backing sheet station 14 can be used for outer sheet material thus providing three stations at which outer sheet material may be delivered to the bottom conveyor 24. This has considerable advantages in providing a substantially continuous course of outer sheet material to the manufacturing process and in providing maximum flexibility for presenting sheet material to the upper and lower conveyors 20,24 as required by the demands of production. For example, the second backing sheet station 14 may be used to supply outer sheet material which may be required only in relatively small amounts. For example, the particular outer sheet material used may be of a colour which is used in small quantities.
By the simple application of a release film on the underside of the top sheet 15 in step 29, a substantial difficulty is overcome. The release film ensures that when the panels are stacked one upon another for storage and transportation, there is a release layer between adjacent panels. We have found that this is particularly important in preventing thermal bonding occurring between the panels in transportation and storage as the panels are still relatively hot on stacking. By providing a release film, the panels may be stacked and transported immediately after production.
In the method of the invention, finished cut panels are automatically palletised. A pallet is always available to receive a cut length of panel and/or a stack of panels to receive another panel is available on demand at the palletising station. In this way, optimum production rates are achieved as the panels can be taken from the main conveyor immediately after cutting and finishing.
In one particularly preferred embodiment of the invention, the spacer blocks which are inserted between the top and backing sheets in the oven as the foam expands are releasably mounted on an endless chain which passes through the oven during expansion of the foam and travels outside the oven to return to the start of the course. We have found it particularly advantageous to releasably mount the spacer blocks on the endless chain as the blocks may then be very quickly and readily changed when it is required to change from one profile panel to the next. The spacer blocks associated with the first panel are simply removed and replaced by another set of blocks associated with another panel. In this way, time required for a changing over from one insulating panel to another is minimised. Further, if any of the individual blocks become damaged, they can be easily replaced in situ without interrupting the manufacturing process.
Referring now to Figs. 7 to 10, the step 45 for applying an edge seal 9 is illustrated in detail. The edge seal 9 is drawn from a supply reel 60 over a series of pulley wheels 61 and through guide tubes 63 and over a seal inserting wheel 65 and a final insertion pusher wheel 66. Adhesive is applied continuously into the recess 7 in the panel in advance of the insertion of the seal 9. The adhesive is delivered from the supply pot 70 through an applicator nozzle 71 in proportion to the speed of travel of the panel along the line so that the uniform amount of adhesive is applied into the seal receiving recess 7. Immediately after the adhesive is applied, the seal 9 is applied to the adhesive by the pusher wheel 66. A strip
3 of adhesive applied behind the seal 9 is diagrammatically illustrated in Fig. 10.
The seal 9 is trained over the various pulley wheels 61 to effectively decoil and straighten the seal prior to application. One of the pulley wheels 61 is driven by a motor 7 5 in proportion to the speed of travel of the insulating panel along the line. In this way the seal 9 is presented for insertion into the recess 7 in the panel in optimum condition and at optimum speed to achieve effective insertion and sealing within the panel without interrupting the panel on the line and without a requirement for manual intervention.
The invention provides a substantially continuous production process for manufacturing insulated panels in a highly efficient manner.
The invention is not limited to the embodiments hereinbefore described which may be varied in both construction and detail.
