Definitions

  • the present invention relates to an apparatus which is primarily designed for packaging a compressed stack of insulating mats in a bag or a sack but can also be used for goods of another kind.
  • the packaging takes place generally by stacking a suitable number of such slabs to a height of, e.g., 0.7-1 m and passing the stack between an upper and a lower plate while exerting a certain compression in the vertical direction.
  • the stack Before its passage between these plates, the stack meets a foil web composed of an upper foil and a lower foil drawn from their respective feed roll and welded together along a horizontal seam located approximately midway between the plates.
  • This composite foil web is drawn along by the stack when passing between the plates, so as to be tightened around the stack, the upper and lower foil being then welded together to form a rather broad seam behind the stack.
  • the seam is cut through along its centre line, so that one portion forms the closure of the package around the stack while the other portion of the seam connects the ends of the next lengths of upper and lower foil to be used for packaging the subsequent stack.
  • the packaged stack can then pass through a shrinking tunnel where the packaging foil is shrunk to such an extent that the height of the stack can be reduced up to 50% when finally packaged.
  • the present invention relates to an apparatus for packaging goods, in particular a compressed stack of insulating mats, in a bag or a sack, and comprising a packaging beak through which the stack is led to the bottom of the bag, after the open end of said bag has been drawn on to the beak around its free end.
  • Packaging of mineral wool slabs has been used for a number of years in the following manner: the height of the stack is first subjected to a reduction of up to 50%, whereafter the stack is pressed forward through the packaging beak, after a prefabricated bag or sack has been manually pulled on this beak so that it can accommodate the compressed stack without allowing it to expand again vertically to an appreciable extent. While continuing its movement through the beak, said stack draws off the sack from the beak, whereafter the mouth of the sack can ' be closed by welding or lacing.
  • This method as hitherto practised requires a substantial amount of personnel, as it presupposes three working stands manned with five persons each, when work is carried on continuously.
  • the main object of the present invention is to provide an apparatus allowing a radical reduction of the staff required, and for this purpose the apparatus according to the invention is characterized by providing, in front of the free end of the packaging beak, a mechanism adapted for receiving and opening flat-folded bags and for drawing them on to the beak, said mechanism comprising two sets of holders with grippers for a respective side wall of the bag, which holders are movable away from each other for the opening of the bag and are further movable from a bag receiving position laterally displaced in relation to the packaging beak to a position in alignment with the beak, in which latter position the grippers while still firmly engaging with the side walls of the bag are displaceable parallel to the packaging beak to place the open bag thereon.
  • this apparatus makes use of prefabricated bags or sacks which can, without becoming economically unwarranted, be made in such a quality that they can stand without breaking the very high inner pressure exerted by the highly compressed stack, rendering a subsequent shrinkage unnecessary, although such shrinkage may possibly be envisaged in special cases.
  • the desired reduction of staff results from the fact that the opening of the flat-folded bags as well as their placing on the packaging beak are carried out fully automatically and in such a way that the various operations do not interfere with each other.
  • the non- interference aspect is the reason why at any rate the initial opening of the bags takes place in a position which is laterally displaced in relation to the packaging beak, thereby allowing the reception and the initial opening of a bag to take place simultaneously with the filling of a preceding bag with a stack of insulating mats passing through the packaging beak.
  • the next bag can, by means of the holders, be opened to a maximum and be shifted to a position opposite the beak and be pushed onto said beak, whereafter the holders can immediately return to their receiving position for preparing the next bag.
  • Fig.1 and 2 indicate horizontal elements belonging to the support (not shown in detail) of the apparatus
  • 3 is a vertical standard forming part of said support.
  • 8 indicates a carriage or slide for carrying forward between the holders 6 and 7 a flat-folded bag 9.
  • This bag 9 can in a conventional manner be fed from a stock or it can, also in a known manner, be made just before from a tubular foil which at suitable intervals corresponding to the desired bag length is sealed by means of a transverse welding seam 10 forming the bottom of the ready bag.
  • Each of the holders 6 and 7, see in particular Fig.2, can be designed as a pneumatic cylinder 11 having a piston rod 12 carrying a gripping head 13 which by suitable control of the pressure fluid admitted to the cylinders 11 is displaceable backwards and forwards, as indicated by the arrows 14' in Fig. 2.
  • the grippers are provided with suction cups 14 and spring clips 15 for temporarily gripping the bag 9.
  • the carriage or slide 8 is displaced to the left from the position shown in Fig.2, until the end of the bag which is held to the carriage or slide 8 by means of a releasable clip 16 has passed the spring clips 15.
  • the grippers 13 are drawn nearer to each other, so that the opposite lateral walls of the bag are grasped by their respective suction cups 14 after establishing a suitable partial vacuum.
  • the clip 16 is then released and the carriage 8 is withdrawn from the space between the grippers 13 which are again moved a little farther from each other to initiate the opening of the bag 9.
  • a pair of angular swinging arms 16 pivotally mounted in the foremost end of the grippers 13 are actuated, said arms being so arranged that their free bent ends, when pivoting in the directions indicated by arrows, land in the spring clips 15 and thereby form an outward fold in each of the two lateral walls of the bag.
  • each of the swing arms 16 can be carried by a shaft 17 in frictional or toothed engagement with a reciprocating driving rod 18 which can, for instance, be actuated by a pneumatic cylinder (not shown) mounted in the associated gripper 13.
  • This beak 19 is provided with a support (not shown) having an upper and a lower endless band 20 running in the directions indicated by the arrows, the paths of which are determined by the guiding and return rollers 21 and 22.
  • the inner and forwardly running band portions converge, at any rate until they meet the guiding rollers 21 and possibly to the region of the return'rollers 22, and they contribute thereby to a vertical compression of the stack of mineral wool mats 23 to be packaged.
