Definitions

  • This invention relates to de- and re-crating machines and, more particularly, is concerned with a drive mechanism in such a machine for actuating a translating bar whose function is to translate a plurality of containers, e.g. bottles, into or out of a crate.
  • DE-A-3328112 describes a de- and re-crating machine employing a four-bar mechanism for driving the translating bar.
  • a drive arrangement for a de- and re-crating machine which comprises a crank plate including a crank arm and which in use is mounted in the frame of said machine for rotation about a fixed axis; a coupler arm pivotally connected at a point intermediate its ends to said crank arm; a rocker arm one end of which is pivotally connected to one end of said coupler arm and the other end of which in use is mounted for pivotal movement to a fixed point on the frame of said machine; a link arm one end of which is pivotally mounted at the end of said crank arm; and a translating bar the outboard end of which is adapted to carry means for supporting a plurality of containers and the inboard end of which is pivotally connected to that end of said coupler arm remote from the pivotal connection between the coupler arm and the rocker arm, and the translating bar also being pivotally connected at a point intermediate its ends to one end of said link arm, whereby rotation of said crank plate causes the crank arm, rocker arm, coupler arm and link
  • the linkage between the crank plate and the translating bar is a four bar mechanism which is able to articulate freely.
  • the fixed pivot points are represented by the centre of the crank plate and by one end of the rocker arm.
  • the crank plate is preferably arranged to be driven through a maximum rotation of 220°. With such an arrangement, arcuate reciprocation of the crank plate results in a movement of the translating bar which has three components, the first component being a relatively long vertical upward movement; the second component being an arcuate movement in a vertical plane; and the third component being a relatively short vertical downward movement.
  • the translating bar remains in a fixed, substantially horizontal orientation. Continued movement of the connecting rod reverses this sequence of movements of the translating bar.
  • the drive arrangement is mounted in a machine frame which also includes a source of motive power and a mechanism for coupling the power source to the crank plate.
  • a mechanism includes a quadrant gear coupled to said crank plate by, for example, a spur gear; and a connecting rod driven by a crank on the output shaft of the motor and connected so as to cause arcuate reciprocation of the quadrant gear.
  • Figure l shows the drive mechanism holding the translating bar in a first position at which it is about to deliver a plurality of bottles to a crate
  • Figure 2 shows the drive mechanism in a second position in which the translating bar is about to collect a plurality of bottles from a marshalling table.
  • the apparatus comprises a frame l which supports a marshalling table 2 over which is positioned an endless conveyor 3,4 the upper belt run 3 of which is shown carrying a plurality of bottles 5. Also mounted on frame 1 is an electric motor and gear box 6 the output shaft of which includes an eccentric drive pin 7 which forms part of a crank arrangement 8.
  • a connecting rod 9 is pivotally mounted at one end of crank 8. The remote end of connecting rod 9 is pivotally mounted at 10 to a quadrant gear 11 which rotates about a fixed pivot 12 in the frame 1. In the illustrated embodiment, quadrant wheel 11 moves through an arc of 81° 44 minutes.
  • An arcuate portion 13 of quadrant gear 11 is provided with gear teeth and contacts a spur gear 14 which is pivotally mounted about an axis 15 which is fixed with respect to frame 1.
  • a crank plate 16 In front of spur wheel 14, and mounted about the same axis, is a crank plate 16 which is arranged to rotate with spur gear 14.
  • Crank plate 16 includes a crank arm 17 which is pivotally connected at 18 to a link arm 19 and is also pivotally connected at 20 to a coupler arm 21. That end of link arm 19 opposite to pivotal connection 18 is pivotally connected at 22 to a translating bar 23. The inboard end of translating bar 23 is pivotally connected at 24 to one end of coupler arm 21.
  • Coupler arm 21 is pivotally connected at 25 to a rocker arm 26; that end of rocker arm 26 opposite pivot 25 is pivotally mounted at 27 on a pivot axis which is fixed with respect to frame 1.
  • Translating bar 23 is thus held by a four bar linkage made up of crank arm 17, link arm 19, coupler arm 21 and rocker arm 26. These four arms are linked to articulate freely with one another through pivotal connections 18, 20, 22, 24, 25 and 27. Pivot points 12, 15 and 27 are fixed with respect to frame 1.
  • the outboard end 28 of translating bar 23 carries a beam (not shown) which in turn supports the grab heads (not shown) which serve either to take bottles out of, or place bottles into, crates such as that shown at 29. These crates are supported on a crate conveyor 30.
  • the gear ratio between rim portion 13 of quadrant gear 11 and spur gear 14 (which is fixed with respect to crank plate 16) is approximately 13:35, so that the maximum arcuate movement of quadrant gear 11 is able to effect a maximum arcuate movement in crank plate 16 of 220°.
  • translating bar 23 is positioned so that the grab heads (not shown) supported by outboard end 28 are located directly above the longitudinal axis of crate conveyor 30.
  • the vertical spacing between crate conveyor 30 and translating bar 23 is arranged so that, in the configuration shown in Figure 1, bottles held in the grab heads are substantially within the confines of crate 29. Thus release of the bottles from the grab heads serves to position the bottles within crate 29.
  • crank arrangement 8 rotates to push connecting rod 9 upwardly, quadrant gear 11 is caused to rotate counter-clockwise which in turn drives crank plate 16 in a clockwise direction.
  • This causes translating bar 23 to move vertically upwardly from the position shown in Figure 1 and then to follow an arcuate movement as crank arm 17 moves towards a vertical orientation and continues its clockwise movement.
  • further rotation of crank plate 16 results in translating bar 23 moving downwardly and vertically by a small distance until connecting rod 9 reaches its maximum upward position which is illustrated in Figure 2.
  • translating bar 23 is positioned so that its grab heads (not shown) are able to cooperate with bottles 5 positioned on the marshalling table 2.
  • the motor 6 will be driven so that eccentric drive pin 7 rotates at a speed of about 12 revolutions per minute. This allows sufficient time for actuation of the grab heads supported by translating bar 23 thus enabling proper transport and transfer of bottles such as 5 to occur.
