Lift tables with mechanical raisers providing for supply of plates for the assembly process can be incorporated.
  • the insulation head/injection device 101 consists of a plate lying flatly down on the framework in which there are two slots. Injection tube/hose runs in the foremost through which the material is supplied to the underlying spaces in the element.
  • the tube can be moved in the slot from side to side and the tube can be turned 280° around so that the injection direction is variable.
  • the tube can furthermore be elevated and lowered relative to the bottom side of the plate such that it projects more or less down into the volume space across which the device is moved.
  • the tube mouth can be shaped according to the direction in which the supplied material is to be delivered. The tube mouth can be adjusted in relation to the size of the opening or it may be changed to a different size automatically or entirely or partially manually.
  • a variable "needle filter” consisting of rods that are lowered down to the bottom of the space. The ends of the rods are rounded in order not to adhere to irregularities in the bottom. Only the number of needles fitting the width of the volume space across which the device is moved are lowered. The redundant needles are held up by a catcher which can be elevated/lowered relative to the actual depth of the volume space. By asymmetric, curved or round spaces, the "needle width" is adapted during the movement. In both slots there is fitted a brush filter or other flexible sealing that seals around the injection tube and the "needle filter". A brush filter can be mounted on the needles at the sides towards the sides of adjacent needles. All filters are applied to prevent or limit material spillage.
  • a meter is provided on the hose for measuring the amount of material supplied under the plate. This measurement determines the speed at which the robot or other control device moves the plate across the element to be filled.
