Definitions

  • This invention relates to improvements in sack mounting machines, ie those machines which mount valve-type sacks on ports through which they are filled for example with pulverulent or grain-like material, such as cement and the like.
  • Such machines are known. They generally comprise a point at which valve-type sacks are loaded horizontally into piles, a point at which sacks are withdrawn one by one from the pile and changed from their horizontal position to a vertical position, and a point in which the now vertical sack is moved horizontally with its valve aperture open and is literally propelled over the filler port which at that moment faces and is aligned with the valve.
  • the devices provided at the point at which the sack is withdrawn from the pile and at which the sack is made vertical move sequentially and hence the cycle is relatively slow, it therefore being the main object of this invention to provide improvements which accelerate the withdrawal and vertically positioning cycle.
  • FIG. 1 A part of the device of the invention is shown schematically in Figure 1 and comprises the sucker device 1, the fixed element 2 and the movable wall 3 cooperating with the fixed element 2, in addition to other parts and components described in detail hereinafter.
  • valve-type sacks indicated by 4 are arranged piled on a known horizontal support table 5 to which they have been transferred in a known manner by known means which do not form part of the invention.
  • the sacks 4 when flattened comprise in known manner two folded ends 4a, b, of which that indicated by 4a carries a usual valve 4c (indicated by dashed lines).
  • the sucker device 1 is shown in detail in plan view in Figure 3 and in side elevation in its two end positions in Figure 4, and operates on the sack end 4a. It comprises a double-acting pneumatic operating cylinder 6, hinged at 7 to the machine structure and having its rod 8 hinged at 9 between two parallel plates 10 rigid with a lever 11.
  • This lever is pivoted at 12 to a part 13 fixed to the machine structure. In a different position on this structure there is hinged at 13 one end of an adjustable rod 14, the other end of which is hinged at 15 to one end of an angle lever 16, the other end of which is hinged at 17 to the lever 11.
  • the four hinge points 12, 13, 15 and 17 define the vertices of an articulated parallelogram, the sides of which are represented by the lines joining said vertices together in pairs.
  • a suction pipe, in the form of a bent pipe 18, is rigidly joined to the angle lever 16 (at its angle) and to a connecting rod 19 also hinged at the point 17 (see Figure 3) to the lever 11 and parallel to said angle lever.
  • the bent pipe 18 comprises a series of suckers 20 suitably spaced apart and can be connected via a controlled valve, not shown, to a source of vacuum and to atmosphere alternately.
  • the suction pipe 18 extends with its suckers 20 projecting towards that side on which the sacks 4 lie in a pile, the described mechanism which operates it being located on one side of this pile (as can be seen from Figures 2 and 3).
  • the suckers 20 act on that end 4a of the sack at which the valve 4c is situated.
  • the machine structure carries (see Figure 5 in particular) a fixed vertical wall 22, which could be adjustable in height, and to the top of which there is connected a horizontal ledge 23 carrying at one end (the right in Figures 2 and 3) a horizontal idle roller 24 which partially emerges from an aperture in said ledge 23.
  • a movable wall indicated overall by 25, provided with a part 26 which during a given period of the operating cycle ( Figure 5) lies vertically parallel to the wall 22, and also provided with a right angled ledge 27 also comprising an idle roller 28 which partially emerges.
  • the movable wall 25 is connected to a lever 29 pivoted at 30 between supports 31 on the machine structure and on which, at 34, there acts the rod 33 of a double acting pneumatic cylinder 32 pivoted at 35 to the machine structure.
  • Two spaced-apart rollers 40 coaxial with each other and with an intermediate driven pulley 41, cooperate with said idle rollers 24, 28 (which as stated slightly emerge from apertures in the relative ledge 23, 27 which carries them).
  • the three components 40, 41 are torsionally connected together and supported at the end of an arm 42 interposed between them.
  • the arm 42 is rotatably supported (at 43) on the shaft of an electric motor 44 driving a pulley 45 which by means of a V transmission belt 46 transmits movement to the wheel and hence to the pair of rollers 40.
  • the rod 48 of a double-acting pneumatic cylinder 47 acts on the arm 42 to raise and lower it from and towards the idle rollers 24, 28 of the driven rollers 40.
  • a usual profiled duct 50 the purpose of which is to open the valve 4c of the sack to enable the sack to be mounted over a rotating filler port 51 by propelling the sack the moment these latter become aligned (see Figure 2).
  • suckers 20 are positioned on the end 4a of the highest sack of the pile lying on the support table 5 ( Figures 3, 4) and that the sucker carrier pipe 18 is connected to a source of vacuum.
  • the suckers which are in pneumatic connection with the pipe 18, retain this end 4a of the sack.
  • a central control unit acts on valve means to feed compressed air into the cylinder 6 in such a direction as to move the articulated parallelogram (vertices 12, 13, 15, 17) from the position indicated by full lines (for sack withdrawal) to the position indicated by dashed lines in Figure 4, so dragging the end 4a of the sack 4 by the relative suckers 20, this end remaining horizontal (see Figure 4) while a part of the remainder of the sack assumes a vertical position and a part (that towards the other end 5b) remains horizontal.
  • the control unit connects the suckers 20 to atmosphere with the result that the sack is abandoned and hence lies in the position shown in Figure 5.
  • the motorized rotating rollers 40 are then lowered against that end 4a of the sack resting on the horizontal ledges 23, 27 on the walls 22, 25, to hence propel the sack 4 towards the filler port 51 by way of the downwardly open profiled duct 50, which opens the valve 4c in order to mount it on the port, as shown by crossed lines. (If another sack is already on the port or if the port is not in position, the rollers 40 are not lowered).
  • the profiled duct 50 is open downwards longitudinally, the sack becomes positioned vertically in its travel after leaving the pile.
  • the articulated parallelogram which controls the sucker carrier pipe 18, brings this latter into engagement with a new sack of the pile.
  • a part of the movement of the sucker carrier pipe 18 can hence be simultaneous with the movement of the movable wall 25. Also, the sucker carrier pipe 18 does not have to wait for the sack to be propelled into the profiled duct before returning to the pile of sacks.
