Definitions

  • Bakery products such as muffins, cupcakes, pound cake and the like are usually baked in a fluted paper shell which is specially treated to withstand baking temperatures and ready release from baking tins or receptacles. While various attempts have been made to provide automatic machinery to dispense such paper shells, such attempts have been only marginally successful. It will be understood that to automate the dispensing of such shells, liners or cup-like members is particularly difficult since a nested stack of several hundred such members, each fluted cup nested within the next adjacent, tends to be tightly and frictionally bound. Furthermore, when a cup is extracted from the stack, the next adjacent cup or cups usually are dislodged due to such frictional engagement and more than one such cup will be dispensed.
  • method and apparatus for individually separating nested cup-like members from a stack thereof, wherein the stack is first secured, for example, in a refillable magazine having an open end and wherein the interior cavities of the nested shells or cups face the open end of the magazine.
  • the cup or shell nearest the magazine opening is retained therein by means such as a plurality of circumferentially arranged fingers which extend radially into the magazine opening.
  • the cups or shells used in baking are usually frusto-conical with the open end of each such member having a larger dimension than its base.
  • the dispensing/extraction process is initiated by the insertion of a suction means (in the illustrated embodiment, a cylinder) having suction ports in an annular pattern arranged about that portion of the cylinder which is inserted within the interior of each cup.
  • a suction means in the illustrated embodiment, a cylinder
  • the cylinder is of a slightly smaller diameter than the base diameter of a cup or shell so that when suction is applied the diverging sidewall of the cup will be drawn inwardly toward the cylinder. This effectively reduces the width of the shell so that it may pass through the opening in the magazine.
  • the nested cups are generally tightly engaged, each adjacent one within the next adjacent one, so that engagement of the suction means with the cup nearest the opening usually causes at least the next adjacent cup to be pulled from the stack at the same time.
  • the invention uniquely provides positive air flow directed externally of the cup engaged by the suction source which separates the cup so engaged by the suction means from the next adjacent one or ones thereof.
  • the positive flow furthermore will not only separate the respective members but will force the next adjacent members back into the magazine to await their respective turn to be withdrawn.

  • Fig. 1 illustrates a bakery product (muffins or cupcake) 10 which has been baked within a fluted shell or cup 11.
  • the cup 11 is conventionally made of paper which has been specially constructed and treated to withstand the temperatures of the baking process and to permit ready release of the product 10 and the surrounding cup 11 from the receptacle 12 (Fig. 7) in which it is baked.
  • the present invention concerns automatic, sequential dispensing of large numbers of such cups 11 (or functional equivalents) individually from a nested stack into bakery receptacles, baking platforms or the like.
  • Figs. 2 - 7 illustrate a plurality of such cups 11 which are so dispensed in accordance with the present invention.
  • Each cup 11 has been manufactured to have a fluted or crimped sidewall 13 and a flat base 14 which define a cavity 16 generally frusto-conical in shape. Cups 11 are uniform in size and shape and thus may be nested each within a next respective cavity 16 to form a stack 17 which may include several hundred cups 11. It will be understood that in such an arrangement, the fluted sidewalls 13 of adjacent cups 11 tightly engage and greatly inhibit individual automatic separation of each cup 13 from a stack 17 thereof.
  • the stack 17 of cups 13, as illustrated, is held within a magazine 18 comprising a plurality of rods 19 which circumferentially surround sidewalls 13.
  • the magazine 18 has a base plate 20 which is removable so that additional cups 13 may be added from time to time to fill the magazine as cups are dispensed therefrom.
  • rods 19 are permanently connected to a plate 21 defining a circular opening 21a therein which permits egress of cups 13 therefrom.
  • Fingers 22 (four to six) are attached to plate 21 and extend radially inwardly within opening 21a. Fingers 22 effectively operate to restrict the diameter of opening 21a to assist in the sequential individual withdrawal from magazine 18 of cups 13 by the cup separation and dispensing apparatus 25.
  • Apparatus 25 includes a central, hollow cylindrical section 26 which preferably includes a suction source known as a vortex generator 27.
  • Section 26 defines one end 26a which as illustrated may be inserted within a downwardly facing cavity 16 of the lowermost cup 13 within stack 17.
  • the diameter of section 26 is essentially the same (allowing for tolerances) as the diameter of each cup base 14.
  • Section 26a defines a plurality of annular ports 28 which are connected to the vortex generator 27.
  • Apparatus 25 includes a hollow, annular ring 29 which as illustrated is connected to an external source of air pressure which directs a controllable flow of air pressure into ring 29.
  • Ring 29 defines a plurality of ports 29a for the direction of air flow therefrom upwardly and parallel to the longitudinal axis of section 26a.
  • Figs. 2 - 5 illustrate the cup dispensing apparatus 25 as it operates to withdraw an individual cup 13 from stack 17 and magazine 18.
  • the means for moving the apparatus 25 toward and away from magazines 18 has been shown in Fig. 5 and shall be described later.
  • section 26a has been shown having been inserted within the cavity 16 of the cup nearest to the opening 21a in magazine 18. It will be noted that without suction being applied from ports 28, the sidewall 13 of such cup rests upon fingers 22 which prevent such cup from moving from the magazine. However, it will be seen that when suction is initiated, the walls of a cup 13 surrounding section 26a will be pulled toward (Fig. 4) and against (Fig.
  • FIGs. 4 and 5 show how apparatus 25 solves withdrawing a single cup A from magazine 18 notwithstanding the fact that a next adjacent cup B has, due to frictional contact, been partially withdrawn from magazine 18 at the same time.
  • the withdrawal force acting on cup A is suction provided by ports 28, whereas the withdrawal force acting on cup B is contact between the sidewalls 13 of cups A and B.
  • Positive air pressure from ports 29a in ring 29 will act in two ways upon cup B to a) separate the frictional engagement between the respective sidewalls of cups A and B and b) to drive cup B back into magazine 18.
  • Fig. 4 and 5 show how apparatus 25 solves withdrawing a single cup A from magazine 18 notwithstanding the fact that a next adjacent cup B has, due to frictional contact, been partially withdrawn from magazine 18 at the same time.
  • the withdrawal force acting on cup A is suction provided by ports 28, whereas the withdrawal force acting on cup B is contact between the sidewalls 13 of cups A and B.
  • Positive air pressure from ports 29a in ring 29
  • pressure from ports 29a shall flow between the engaged sidewalls and also outside the sidewall of cup B, the latter acting aerodynamically in concert with pressure between the respective sidewalls.
  • the upward pressure from ports 29a has driven cup B away from cup A and into the magazine where further upward pressure will force the lower edge of cup to rest upon and be restrained by fingers 22 until the next dispensing cycle has begun.
  • apparatus 25 is provided movement in two directions within carriage 30 comprising a base 31 rigidly secured to longitudinal members 32 at one end. The opposite ends of such members slideably engage and laterally support ring 29. Plate 33 is attached to members 32 and has been provided with a circular opening 33a to permit retraction therethrough of section 27 of apparatus 25 by piston and piston rod 34 and 35. Such movement shall be automatically controlled by sensors well- known in the art.
  • the second kind of movement of apparatus 25 provided by carriage 30 is rotation of apparatus 25 from and to the respective positions of Fig. 2 and Fig. 7. To accomplish such rotation carriage 30 is connected by a bracket 36 to rotary actuator 37 which shall be secured to stationary adjacent structure (not shown) .
  • Fig. 6 illustrates rotation of apparatus 25 from the position of Fig. 5 (full withdrawal from magazine 18 to an intermediate position) .
  • Fig. 7 illustrates further rotation of such apparatus to a position in which it shall dispense a cup 13 into a receiving cavity 38 in a receptacle 12.
  • suction from ports 28 shall be discontinued which will cause cup 13 to begin to assume its original frusto-conical shape (see dotted outline) .
  • positive pressure will flow from ports 29a to literally "blow" cup 13 into cavity 38 completing the dispensing cycle.
  • Figures 8-12 illustrate high production cup dispensing machinery incorporating the principles of the present invention:
  • Figure 8 is a front elevation thereof;
  • Figure 9 a partial top view thereof;
  • Figure 10 is a section through the top view of Figure 9.
  • the high production machine illustrated includes a main disc 50 and an outer disc 51 which are attached to pairs of support rods 52, 53 extending laterally between each disc 50 and 51.
  • cup retainer plates 54 Between rods 52, 53 are cup retainer plates 54 which define therein circular cup retainer openings 56 (see also Figure 10A) .
  • a plate 57 Secured to the upper surface of plates 54 around each opening 56 is a plate 57 through which a cup 13 may freely pass when drawn therethrough by an extractor head 25.
  • each cup retainer plate 54 Secured to the lower surface of each cup retainer plate 54 and about each opening 56 therein is a circular stripper plate 58 which is of a sufficiently reduced diameter to effect stripping of a cup 13 from an extractor head 25 as the head 25 moves entirely through one of the cup retainer openings 56.
  • Such movement of each cup 13 through an opening 56 shall be coordinated with cessation of suction from extractor head 25, thereby releasing each cup into a cup retainer opening 56 and permitting expansion of the sides of a cup 13 to a diameter greater than the diameter of the opening in stripper plate 58.
  • the described deposition of cups 13 into respective retainer openings 56 in plates 54 shall be simultaneously achieved by the plurality of extractor heads 25 as illustrated.
  • FIG. 11 illustrates an extractor head 25 in its top dwell position and is similar to the sectional view shown in Figure 10.
  • Figure 12 illustrates the extractor head 25 in its bottom dwell position. In the top dwell position, the extractor head is positioned to withdraw a cup 13 from a stack thereof as heretofore described.
  • FIGs 10, 10A, 11 and 12 further illustrate the arrangement of cup retainer plates 54, cup retainer openings 56 and stripper plates 58.
  • retainer plates 54 there are six retainer plates 54, each attached to circular end discs 50, 51 for counter-clockwise rotation of discs 50, 51 together with cup retainer plates 54 as viewed in the drawing.
  • Six retainer plates 54 are attached to discs 51 spaced apart at angular intervals of 60 .
  • FIG 8 it will be seen that to the left of main disc 50 there has been diagrammatically illustrated a pulley 60 which is connected by belt 61 to a pulley 62, drive train shafts and gearing 63, the latter enclosed within gear housing 64.
  • a central drive shaft 66 is connected to the center of main disc 50.
  • FIG. 10-12 power fed to main disc 50 shall move discs 50,51 counter-clockwise. Movement of extractor heads 25 from the top dwell position of Figure 11, to the bottom dwell position of Figure 12, shall be accompanied by 60 rotation of discs 50,51; but only after heads 25 have reached the bottom dwell position and are clear of retainer plates 54.
  • each of the extractor heads 25 are attached to a plate 65 extending laterally behind the array of heads 25, as viewed in Fig. 8.
