Definitions

  • ABSTRACT Mechanism for reciprocating the press of a stackforming implement utilizes hydraulic energy so arranged as to decrease the time consumed during each pressing operation.
  • the forces imparted by fluid pressure piston and cylinder assemblies are, in effect, reversed by unique arm and link arrangements such that the pressing stroke takes place as the piston stems are extended and the press is moved rapidly along its return stroke during retraction of the stems.
  • Synchronization is effected by intermeshing gear teeth between each of two pairs of power transmitting arms or beams and by an operable interconnection through use of a torque member, the linkages being so connected as to apply equalized forces at each of four corners of the press.
  • An important object of the present invention is to provide actuating mechanism for a press of the kind disclosed in said patent, for example, which will increase the speed of the press operation.
  • Another important object of the present invention is to provide a press control which permits the use of hydraulic energy while, at the same time, eliminates the resultant slowdown when such type of energy is used and coupled in conventional manners.
  • Still another important object of our instant invention is to make use of fluid pressure piston and cylinder assemblies for the aforementioned purpose in a manner to eliminate need for any type of control to equalize the fluid flow to the assemblies in order to distribute the forces uniformly to the press.
  • FIG. 2 is a fragmentary vertical cross-sectional view taken on irregular line 2-2 of FIG. 11;
  • FIG. 3 is a fragmentary, detailed cross-sectional view taken on line 3-3 of FIG. 1.
  • the mechanism includes a pair of substantially identical arms or beams 18 and 20 which, in the form chosen for illustration, are essentially triangular in configuration. Arms 18 and 20 are mounted'on the body it exteriorly thereof for vertical swinging movement about horizontal shafts 22 and 24 respectively, shafts 22 and 24 projecting outwardly from reinforcing studs 26 and 28 respectively forming a part of the proximal sidewall of the body 10.
  • the outer ends of the shafts 22 and 24 are supported by elongated straps 30 and 32 respectively attached at their lower ends by corresponding pins 34 and 36 projecting outwardly from the studs 26 and 28.
  • a crossbar 38 adjacent the straps 30 and 32 interconnects the shafts 22 and 24.
  • the same identifying numerals suitably primed designate the components of the mechanism 116 shown in FIG. 2.
  • a fluid pressure piston and cylinder assembly 52 pivotally interconnecting the body 10 and the arm 18, includes a cylinder 54 having a piston 56 reciprocable therein and a piston stem 58 extending upwardly and outwardly beyond the upper end of the cylinder 54.
  • the cylinder 54 is adapted to receive hydraulic pressure at both ends thereof, rendering the same double acting, and the pin 34 serves to pivotally connect the cylinder 54 at its lower end with the body 10.
  • a pivot pin 60 couples the outer end of the stem 58 with the gear tooth segment 48 of the arm 18.
  • the return stroke of the press 12 takes place during retraction of the piston stems and that therefore the upward movement of the press 12 is relatively rapid because the fluid capacities of the cylinders above their pistons are less than the capacities of the cylinders below their pistons. That is to say, the presence of the stems within the cylinders during downward movement of their pistons reduces the volumetric capacity of the cylinders above their pistons. Accordingly, by virtue of the coupling between the hydraulic assemblies and the press 12, which includes the two sets of arms 18 and 20, together with the two sets of links 40 and 42, the speed of travel of the press 12 during its upward stroke is greater than the speed of descent of the press 12 when it is under a working load. That feature, together with the parts played by two sets of intermeshing teeth 48, 50 and the torque member 62 as above described, contributes to the improved performance made possible by the principles of the instant invention.
  • each mechanism comprising:
  • a double acting, fluid pressure, piston and cylinder assembly having a cylinder provided with a reciprocable piston and adapted for receiving fluid under pressure at opposide ends of the piston, said piston having a stem extending outwardly through one end of the cylinder;
  • each mechanism comprising:
  • a double acting, fluid pressure, piston and cylinder assembly having a cylinder provided with a reciprocable piston and adapted for receiving fluid under pressure at opposite ends of the piston, said piston having a stem extending outwardly through one end of the cylinder;
  • said restraining means including an operable connection between the beams of each mechanism respectively for swinging the beams in opposite directions with respect to one another and means interconnecting the two mechanisms,
  • said interconnecting means including an elongated torque member, means supporting said member for rotation about its longitudinal axis, and means coupling opposite ends of the member with the mechanisms respectively for rotating the member in response to actuation of the mechanisms.
  • crop receiving structure including a hollow open top body having a pair of spaced, upright sides and a hollow open bottom press, reciprocable vertically in said body,
  • said press being provided with a roof and with a pair of spaced, upright sides;
  • each link extending upwardly from a corresponding arm
  • each power means comprising a fluid pressure piston and cylinder assembly.
  • each assembly pivotally interconnecting the body and one of said arms.
  • each arm having a first upper end and a second end spaced from said first end
