Definitions

  • the present invention relates to an automatic press for pressed pots (bumps) with continuous feeding of the pots with the material to be treated and automatic strapping of the pressed coils.
  • ribbons of fibers are used, collected in cylindrical pots, with a spiral distribution capable of allowing their successive use by simple scrolling.
  • Said ribbons can be packaged in pressed coils, that is to say by retaining the cylindrical shape and the spiral winding which they have in the pots, but reducing their volume by pressing and strapping.
  • squaring of pressed pots is carried out, which consists of transforming, by pressing and additional strapping, the initial cylindrical shape into a cubic or parallelepiped shape.
  • a first known type of press for pressed pots ( Kiev St. Eloi), provides for the bottom of the pots to be made with a central hub and a plurality of articulated radial arms so that they can be, on command, open or closed, with a movement similar to that of the tentacles of an octopus . During the recovery of the ribbon in the jar, the arms are open to allow the ribbon to settle on it.
  • the same known press comprises: a first operating cylinder with vertical axis, the rod of which is intended to hang on the bottom hub to press the ribbon contained in the jar from below, and a second operating cylinder with vertical axis, the head of which has the same shape as the bottom of the pots and is intended to press the ribbon of the pot from above; a strapping head, for applying four strips closed in a ring and a cross with respect to each other and means for gripping and unloading the pressed and strapped pot.
  • the object of the present invention is to eliminate the aforementioned drawbacks and to propose an automatic press for pressed pots of high production, of limited cost, suitable for packaging pressed pots of cylindrical and parallelepiped shape.
  • the advantages obtained thanks to the present invention essentially consist in what is obtained: high reliability and reduced maintenance thanks to the simple and robust construction; considerable productivity thanks to the simultaneous pressing and strapping of the ribbon; a strapping operation having a reduced cost, because it is carried out with a single head which quickly performs, in succession, the strapping with the desired step; a limited cost, thanks to the simplicity of constructive construction of the removable bottom of the pots used during the operation; a lower cost of packaging pressed jars of parallelepiped shape, obtained on the same press with two successive operations; completely automatic management of the entire operating cycle using a simple programmable logic computer.
  • FIG. 1 shows a perspective view of a press according to the invention for pressing cylindrical pressed pots
  • Fig. 2 shows a perspective view of a press according to the invention for the pressing of pressed parallelepiped pots
  • Fig. 3 shows a detailed vertical section view of a pot for the press of FIGS. 1 and 2.
  • a third box 26 extending horizontally, coplanar but in an orthogonal direction relative to the second box 8 and with a roughly equal rectangular section, which is open at its ends and with a lateral opening for the entry of pots pressed in correspondence with the outlet of the strapping device 20.
  • a head 29 provided inside said box 26 and with an alternating movement printed by an operating cylinder 28 is provided for controlling the advance by pushing of the pressed pot 22 which has been encircled with strips 21 parallel to the longitudinal direction of said box 26 to the outlet mouth and therefore with an intermittent feed with a step not equal to that of the straps 32 to allow cross strapping performed by a second automatic strapping device 31 also fixed.
  • the head 13 of the thrust cylinder 14 located in the second box 8 is flat to allow the material to be compressed against the opposite wall of the third box 26 and, in addition, a side wall 80 of said second box 8 is rotating around a vertical axis and is slaved to an operating cylinder 25 with horizontal travel to allow the material to be compressed in the direction perpendicular to that of the cylinders 15 and 16 which carry out the first pressing in the vertical direction.
  • a press for pressed pots with simple strapping of the type of FIG. 1 is as follows.
  • the head 6 of the cylinder 5 reduces the height of the ribbon 18 which projects beyond the pot 9 to that of the pot itself; successively, the pot 9, with the ribbon thus partially pressed, is moved forward in the pressing station 7, the material remaining at the edge of the pot because this edge touches the upper wall of the box 1.
  • the pot 9 is positioned in line with the cylinders 15 and 16, both with the heads in the lowered position: the planar circular head 17 of the upper cylinder 15 of back pressure being at the level of the lower wall of the box 8 and the head of the lower pressure cylinder 16 being below the circular opening 23 provided in the bottom wall of box 1.
  • the head of the cylinder 16 is raised by cooperating with the removable bottom 10 of the pot which it pushes upwards; with an appropriate adjustment of the back pressure of the upper cylinder 15, the head 17 of which gradually retracts up to the level of the upper wall of the box 8, the cylinder 15 presses the material, which is transferred into the second box 8 reducing to the height of the latter.
  • the head 13 of the operator cylinder 14 which, in the rest position, has its semicircular profile 19 in correspondence with the edge of the circular openings 81 of the box 8, pushes the pressed material in cylindrical form 22, until causing it to protrude from the outlet mouth of what is necessary to apply, by means of the fixed automatic strapping device 20, a first strapping strip 21; then the pressed pot is pushed forward by the cylinder 14 several times, intermittently, with displacements in front of constant pitch to allow the application of as many equally spaced strips; simultaneously, the pressing cylinder 15 reverses its course by bringing the bottom of the pot to the lowered rest position and allowing the evacuation of the corresponding empty pot.
  • the pressed pot 22, thus circled is evacuated from the box 8; the head 13 of the cylinder 14 is brought back to the initial position and, successively, the cylinder 16 reverses its course, bringing its head back to the initial position lowered, and in this way in position for pressing another coil. At this point, the empty pot is evacuated through the outlet outlet of the box and the next full pot is transferred to the pressing position.
  • a press of the type illustrated in FIG. 2 and the operation of which is as follows.
  • the movable wall 80 When the pressed material, in cylindrical form, is in the box 8, the movable wall 80, pushed by the cylinder 25 against the fixed opposite wall, performs the horizontal pressing of the initially cylindrical coil, which is located with two opposite flat faces . Successively, the flat head 30 of the operating cylinder 14 moves the pressed pot under the automatic strapping device 20 which performs the first strapping with several parallel strips 21. After which the coil thus pressed and encircled is subsequently pushed by the flat head 30, through the opening 27, into the third box 26 and pressed against the opposite wall so as to make the two faces of the coil which are parallel to the plane plan of the first strapping.
  • the coil 33 pressed in parallelepiped shape with the section of the third box 26 is pushed by the flat head 29 of the cylinder 28 beyond the outlet mouth of the box 26, so that the second automatic strapping device 31 performs the second cross strapping.
  • the coil 33 thus pressed and strapped is evacuated from the box 26 and the head 29 of the cylinder 28 is brought back to the initial position.
  • the cylinders 8, 15 and 14 reverse their course by bringing their heads back to the initial position, ready for pressing another pot.
