  • Stretch wrappers are very convenient packing machines, which are used to wind a plastic film around an object or a group of objects stacked on a pallet. A stretch wrapper includes a main unit, and a rotary platform. The main unit has a roll of plastic film thereon, and a cutter for cutting the plastic film. Thus, a plastic film will be wound around an object by means of actuating both the main unit and the rotary platform when the object is supported on the rotary platform; the cutter of the main unit will cut the plastic film after the winding process is finished. After the cutting action, a tail end portion of the plastic film is prone to project from the object and move around. Consequently, an electronic sensing and positioning equipment in the warehouse will make mistakes because of the projecting tail end portion of the plastic film around the object.
  • Conventionally, the tail end portion of the plastic film is manually adhered to the object to prevent such a mistake from happening. In light of the fact that time and labor can be saved if automatic adhesive tape applying machines are used to adhere the tail end portion of the plastic film on the object instead of hands, an adhesive tape applying machine is made available by the inventor.
    • SUMMARY OF THE INVENTION
  • It is a main object of the invention to provide an adhesive tape applying machine for use with a stretch wrapper to overcome the above-mentioned problem. The adhesive tape applying machine includes two first power sources secured in vertical position, a moving rod joined to output rods of the first power sources at two ends, a second power source connected to the moving rod with an output rod being displaceable in a horizontal direction, a supporting seat joined to the output shaft of the second power source, and an adhesive tape applying mechanism, which is supported on a lower end portion of the supporting seat, and which will apply adhesive tape on an object when it is pressed against and displaced relative to the object. The machine is positioned next to a stretch wrapper such that after the stretch wrapper winds a plastic film around an object, adhesive tape will be stuck on the object and a tail end portion of the plastic film.
