Definitions

  • This invention relates to a stepping device for moving a movable reaction member by an operating member after a selectively predetermined amount of movement of the operating member.
  • Such stepping devices are used for many purposes and customarily employ an apparatus that is movable through successive increments in a cycle with means at the completion of the cycle for moving a reaction member. The operating member is then returned to its initial condition to start a subsequent cycle.
  • One of the features of this invention therefore is to provide an improved stepping device formoving a movable reaction member only after a selectively predetermined amount of movement of the operating member with this cyclical amount of movement being repeated after each movement of the reaction member.
  • FIGURE 1 is a fragmentary side elevational view of a portion of a meat patty molding apparatus employing one embodiment of the stepping device of this invention.
  • FIGURE 2 is a fragmentary plan View of the machine of FIGURE 1 with the top cover of the stepping device removed for clarity of illustration.
  • FIGURE 3 is a fragmentary side elevational view taken from the right-hand side of FIGURE 2.
  • FIGURE 4 is a plan view of the stepping device of this invention with the ⁇ top cover removed.
  • FIGURE 5 is a vertical sectional View taken substantially along line 5 5 of FIGURE 4.
  • FIGURE 6 is a vertical sectional View taken substantially along line 6-6 of FIGURE 4.
  • FIGURE 7 is a vertical sectional view taken substantially along line 7-1 of FIGURE 5.
  • FIGURE 8 is a View similar to FIGURE 7 but showing the rotatable member in a different position.
  • This apparatus comprises a cabinet 10 on which is located an endless belt 11, one end of which passes over an adjustable pulley 12.
  • This belt 11 is driven by electrically operated means (not shown) in the customary manner andis located so as to receive patties falling from a rotatable mold plate 13 containing four equally spaced mold openings 14 of patty shape adapted to be lled with the moldable material such 3,222,935 Patented Dec. 14, 1965 ICC as ground meat under pressure by .feeding means not shown here but shown in the above-mentioned patent.
  • the vertical shaft 21 within the housing 20 operates through gearing to rotate continuously a sprocket 22.
  • This sprocket 22 rotates by means of a chain 23 and a second sprocket 24 which is mounted on the outer end of a rotatable member or shaft 25 of the stepping device 26.
  • the stepping device has a metal casing 27 with opposite sides 28 and a front 36.
  • the shaft 25 extends between these opposite sides 28 with the outer end 29 of the shaft beyond its adjacent side 28 having fastened thereto the sprocket 24.
  • a collar 30 mounted on the shaft 25 for rotation therewith is a collar 30 within the casing 27 having an outwardly projecting spur 31.
  • a bearing 32 Surrounding the shaft 25 at the area where it passes through the side wall 28 is a bearing 32 in which the shaft 25 is rotatable and also slidable longitudinally relative thereto. Between the collar 30 and the bearing 32 is a compression spring 33 surrounding this portion of the shaft and urging the shaft 25 to the right as viewed in FIGURE 4.
  • the end of the shaft 25 opposite the spring 33 carries a lever 34 extending from a collar 35 attached to this end of the shaft 25.
  • a shaft 37 Extending through the front wall 36 of the casing 27 is a shaft 37 on the outer end of which outside the front 36 is mounted a control knob 38.
  • the inner end of this shaft 37 within the casing 27 carries a stop member 39, here exemplified by a sprocket 40 provided with a hub 41.
  • This hub 41 carries on its inner surface an inwardly extending stop 42 in the form of a pin having a rearwardly and downwardly sloped stopsurface as viewed in FIGURE 4.
  • the shaft 37 and stop member 39 can be rotated by means of the knob 38 through slightly'less than 360. The extent of rotation is governed by a projection 43 on the outer surface of the sprocket 40 engaging a second 'projection 44 on the inner surface of the front wall 36 of the casing.
  • the two projections 43 and 44 engage eachother to deline each end of the arc of rotation of the stop member 39.
  • a bracket 46 having an upwardly extending flange 47 parallel to and spaced inwardly of the inner surface 48 of the hub ⁇ 41.
  • a stub shaft 49 which is axially aligned with the knob shaft 37.
  • an operating member 50 here exemplified by a collar 51 having one end adjacent the flange 47 and on ⁇ which is mounted a sprocket 52.
  • the sprocket 52 is the same size asthe sprocket 40 and has the same number of teeth.
  • a stop engaging pin 53 Extending outwardly from the surface of the collar 51 that is opposite the sprocket 52 is a stop engaging pin 53.
  • This stop engaging pin has an outer end sloped similarly but opposite to the outer end of the pin 42 so that when the pins are in engagement with each other, as shown in FIGURE 4, the stop pin 42 prevents further movement of the operating member 50 in a clockwise direction as viewed from the front of FIGURE 4.
  • the operating member is adapted to move a reaction member 57 after a selectively predetermined amount of movement of the operating member 50.
  • the reaction member 57 is in the form of a hinged plate having a lower end hingedly mounted on a transverse shaft 58 at the bottom of the casing 27 and the upper end positioned between the hub 41 and collar 51 on one side and a slidably mounted plunger 59 on the other side.
  • This plunger is mounted for movement in an opening on one side of the casing 27 and when moved to the right, as shown in FIGURES 4-6, is adapted to close a switch 60.
  • the plate 57 is moved to this switch closing position either by engagement of the plate S7 with a pin 61 extending radially from the hub 41 or pin 62 extending radially from the collar 51 of the operating member 50.
  • the hinged plate 57 is constantly urged toward the hub 41 and collar 51 by means of a helical spring 63 around the shaft 58 having one end bearing against the casing 27 and the other end bearing against the hinged plate 57.
  • the urging of the plate 57 to the left, as viewed in FIGURES 4-6, causes the end of the pin 62 to be held in a recess 64 in the plate 57 until the plate is moved to the right against the urging of the spring 63.
  • This movement of the hinged plate or reaction member 57 further to the right from the position shown in FIGURES 4-6 is brought about by means of the lever 34.
  • This lever which projects from the collar 35 is provided with an inner sloped surface that is sloped from a relatively sharp leading edge 66. Rotation of the lever 34 causes this sloped leading edge 66 to engage a similar but oppositely sloped edge 67 on the hinged plate 57 and move the plate further to the right, as shown in FIGURES 4 and 6. Furthermore, this engagement of the edges causes the plate 57 to be retained in this locked position for a short time.
  • the collar 51 is hollow and contains a coil spring 68 having the inner end attached to the shaft 49 and the outer end attached to a pin 69 on the collar 51. This spring 68 always urges the operating member 50 in a clockwise direction as viewed from the front of FIG- URE 4.
  • the operation of the device is as follows: When the stop member 39 is turned to the position shown in the drawings by the knob 38, the pin 61 is in contact with the hinged plate reaction member 57 to hold the switch 60 closed. Because the spring 68. holds the operating member pin 53 of the operating member 50 against the stop pin 42, the pin 62 is also in contact with the plate 57. The closing of the switch 60 causes the belt 11 to move continuously so that patties are deposited thereon in series or, in other words, in stacks of one. Thus the device now is operating solely to hold switch 60 closed.
  • the knob 38 is turned to the right, as viewed from the front of FIG- URE 4, to position the stop pin 42 of stop member 39 a desired clockwise distance from operating member pin 53.
  • This position can be predetermined by counting the number of clicks as the teeth of sprocket 40 of stop member 39 pass over the spring pressed ball 56. Because sprockets 40 and 52 are identical, the total number of clicks will be the number of patties that will be arranged in each stack.
  • the continuously rotating shaft 25 of the device causes spur 31 to engage each tooth of sprocket 52 of the operating member 58 in succession.
  • This moves the operating member 50 one increment (equivalent to the distance between adjacent teeth) of the total distance the pin 62 must be moved to engage the plate 5'7.
  • These total increments move the operating member 50 in a counterclockwise direction as viewed from the front of FIGURE 4 in steps eventually to engage the operating member pin 62 with the plate 57 and again close the switch 60.
  • the conveyor 11 is moved to place the conveyor in position to receive the next stack.
