    • Detailed Description
    Referring to the drawings there is illustrated part of a method and apparatus used for manufacturing an insulated panel length 1 of the type having an external skin, an internal backing tray and an insulating core between the external skin and backing tray.
    Referring initially to Figs 1 and 2 a continuous length of panel 1 is formed and delivered to a cutting station 2 at which the panel 1 is cut to a desired length by a cross-cut saw 4. The panel is cut to provide a leading panel 10 with a trailing end 11 and a trailing panel 12 having a leading end 13. A first clamp comprising a first upper clamping head 20 and a first lower clamping head 21 grips the leading panel 10. A second clamp comprising a second upper clamping head 22 and a second lower clamping head 23 grips the trailing panel 12. The first and second clamps are mounted on separate carriages 24, 25 which are moved apart as illustrated in Fig. 3 to separate the panels 10, 12 at the joint. The carriages 24, 25 on which the clamps are mounted to travel with the panels as they progress along the production line. This ensures that processing time is optimised as the panels are not stopped during the separation of the panels. At this stage the trailing end 11 of the leading panel 10 is separated from the leading end 13 of the trailing panel 13. The end faces have a rough finish after the cutting process and may be contaminated by metal shards, and dust of foam material.
    Cleaning apparatus for simultaneously cleaning and de-burring the end faces 11, 13 of the adjacent panels is illustrated in Figs. 5 to 10. The cleaning apparatus comprises a cleaning carriage 50 which is mounted for vertical movement in the direction of the arrows A, for example by a ram. The carriage 50 is also movable in the direction of the arrows B transversely of the panels 10, 12 along tracks 51 for movement of the carriage 50 across the gap between the separated panels 10, 12. In use, the carriage 50 is moved from the raised inactive position of Figs. 5 and 10 to the extended or lowered active position of Figs. 7 and 8 and is then driven across the gap created between the panels 10, 12 to clean the end faces 11, 13. Material removed on cleaning is collected in lower collection hoppers 52 to prevent contamination in the region of the panels.
    The carriage 50 carries a leading panel cleaning head 55 and a trailing panel cleaning head 56. The leading panel head 55 has pairs of upper and lower brushes 60, 61 and de-burring knives 63 between the pair of upper brushes 60. Similarly, the trailing panel cleaning head 56 has pairs of upper and lower brushes 63, 64 and de-burring knives 65 between the upper brushes 63. As the carriage 50 is moved across between the panels 10, 12 in the direction of the arrow B in Fig. 9 the brushes 60, 61, 63, 64 brush off debris from the ends 11, 13 of the panels 10, 12 and the knives 63, 65 drag on the uppermost metal edge of the panels, removing metal shards. The lowermost metal edge of the panels may be similarly de-burred.
    After end cleaning the carriage 50 is lifted back up to the inactive position, the panels 10, 12 travel to the next station at which the faces of the panel are cleaned and the cutting, cleaning and de-burring station is ready for the next panel.
    Referring to Figs. 10 to 13 to clean the upper and lower faces 70, 71 of a panel 10, the panel is led over a lower face cleaning brush 80 and under an upper face cleaning brush 81 at a panel face cleaning station 85. In this case the brushes 80, 81 are provided in the form of belts that brush across the faces 70, 71 of the panel 10 as the panel travels along a conveyer 86. Debris is brushed into inlets 87 of a vacuum removal system 88. Both the upper and lower face cleaning brushes 80, 81 are movable from a raised to a lowered position by any suitable means such as a ram.
    The invention provides a highly optimised process for producing insulating panels in which the panel is cut to a desired length in-line, the end faces are cleaned and de-burred and the panel faces are cleaned in-line without interrupting the production panel flow. Substantially clean faces are provided which assists in optimising use of the panels and preventing damage caused by loose metal shards or debris which may damage the panel faces or ends.
    The invention is not limited to the embodiments hereinbefore described which may be varied in construction and detail.
