Definitions

  • the present invention refers to a variable end-of-stroke device for the raising and lowering of a pressing arm in a fixed column and rotating platform winding apparatus.
  • winding equipments that are made up of a support base including a motorized rotating platform for the support of the articles and of a fixed column for the support of a reel of windable film that rises and descends along the column are generally used.
  • an article pressing arm with an end plate or disk, which a suitable pneumatic cylinder raises to enable the articles to be placed on the rotating platform and then lowers to press on the top of the articles.
  • Object of the present invention is to produce a device for raising and lowering a pressing arm in a rotating platform and fixed column winding apparatus, that permits a wide variation of the upper and lower limits of the stroke of the pressing arm.
  • this object is achieved with a device comprising a pneumatic cylinder that extends vertically along the reel support column, an arm-holder trolley that can be raised and lowered along said column and connection means between said cylinder and said trolley, characterized in that said connection means can be moved between hooking points at different heights along the vertical axis of the trolley.
  • FIG. 1 shows an elevation view of a winding apparatus including a device for raising and lowering the pressing arm in accordance with the present invention
  • FIG. 2 shows an enlarged representation of the zone for hooking the stem of the cylinder to the arm-holder trolley
  • FIG. 3 shows the above-mentioned hooking zone in transversal section according to the line III-III of FIG. 2;
  • FIG. 4 shows the trolley and its points of hooking to the stem of the cylinder in axial section
  • FIG. 5 shows only the trolley seen from right with respect to FIG. 4.
  • FIG. 1 shows schematically the assembly of a winding apparatus composed of a base 1 incorporating a suitably motorized rotating platform 2 for the support of the articles 21 to be wound, a fixed column 3 for the vertical sliding support of a reel-holder trolley (not shown) and a pressing arm 4 in turn vertically sliding along the column 3 .
  • the pressing arm 4 is composed of a horizontal arm 5 , which at one end carries a pressing plate or disk 6 that freely rotates around its own axis and at the other end is firmly fastened to a trolley 7 , which thanks to idle wheels 8 can slide along a vertical guide 9 fastened to a side of the column 3 .
  • the trolley 7 is constituted of a C-shaped section bar 10 with right angles, from which four idle wheels 8 extend on the sides.
  • the ascent and descent of the trolley 7 along the vertical guide 9 is controlled by a pneumatic cylinder 11 fastened to the above-mentioned side of the trolley, from which a piston stem 12 extends terminating with a bored head 13 , which is intended for hooking onto the trolley 7 .
  • the trolley 7 provides for two hooking points 20 at different heights along the axis of the trolley, constituted by eyelets 14 having one part 15 narrower and one part 16 wider (FIG. 5).
  • eyelets 14 having one part 15 narrower and one part 16 wider (FIG. 5).
  • the head 17 of a screw 18 can be passed through the widened part 16 , which passes through the bored head 13 of the stem 12 and ends in a screw knob 19 (FIGS. 3 - 5 ).
  • the pressing disk 6 can be moved between the two positions indicated with a continuous line in FIG. 1. If instead the stem 12 is attached to the upper end of the trolley 7 , position indicated by a dotted line in the FIGS. 2 and 4, the pressing disk 6 can be moved between the two positions indicated by a dash-dot line in FIG. 1. The range of heights of the articles that the winding apparatus can receive is evidently high.
