Definitions

  • the invention of the present patent application is encompassed within the procedures and machinery dedicated to bagging, with plastic, manufactured articles and in particular for bagging pillows to avoid deterioration or fouling during transport and handling.

  • Bagging machines that use two plastic reels bag the pillow between two separate layers of plastic, one upper and one lower provided each by a different plastic coil. Subsequently they proceed to the thermal welding of the four sides of the package formed by the lower layer of plastic, the pillow and the upper layer of plastic to, once finished, cut the excess material.
  • These machines therefore, to bag a pillow need to make four welds and four cuts of material complicating the structure of the machine and obtaining a final bagging of worse resistance and worse quality than that obtained with the process and the machine of the present invention.
  • the machines for bagging pillows that use a single plastic coil deposit the pillow on a plastic layer of sufficient length to later fold part of that layer on the upper face of the pillow such that this is between two layers of plastic forming a parallelepiped open on three sides. Subsequently they proceed to thermally seal the plastic through the three open edges, leaving the pillow enclosed in a bag that has therefore been constituted from a plastic coil.
  • This type of bagging has the disadvantage that three welds and three cuts of excess material are needed to form a bag, which mainly entails in terms of machine complexity, processing time, quality of adjustment of the bag to the pillow and mainly robustness of the final bagging.
  • the longitudinal axis of the machine is understood as the direction in which the feeding and transfer station of pillows, the carriage and the station for forming the bag.
  • the transverse axis of the machine is understood as the one constituted by the direction, perpendicular to the previous one, in which the carriage and the compacting and sealing station of the bag are aligned with the pillow.
  • the procedure of bagging pillows proposed by the present patent application consists in using a coil of plastic tube from which its free end is opened and, keeping it open on the claws of a car, a certain length of plastic tube is extracted of the coil, a heat welding is carried out at a distance from the free end slightly greater than the length of the pillow to be bagged, a cut is made along a line parallel to the weld and just where it ends in such a way that it is constituted a bag closed by one of its ends in which the pillow to be bagged is introduced which has been previously, and in a temporary way, compacted laterally in its longitudinal direction (the largest dimension) thanks to a transfer of parallel blades to facilitate thus its introduction in the bag. Finally, the bag is compacted with the pillow and closed.
  • the procedure of bagging pillows is such that, when any of the different stations of the machine that execute the procedure he finishes his particular task corresponding to a certain cycle, prepares for the next cycle. In this way, for example, it is allowed that while a compaction and sealing of a bag with a pillow is being carried out at the same time a new pillow is being packed and another pillow may be being fed by the belt conveyor.
