8 Claims. (CI. 53-59) This invention relates to a machine for receiving hamburg patties or the like from a hamburg patty making machine of the nature shown in Patent 2,795,816, dated June 18, 1957, and stacking the patties. As shown in said patent, the patties are cut from the forward end of an extruded strip of ground meat and slide therefrom by gravity down an inclined chute.

Our novel stacking machine is inclined from the horizontal to cooperate with the inclined chute and receive patties therefrom for stacking. The stacking mechanism includes a platform inclined to receive the patties direct and successively from the chute and elevate them to predetermined position and into a stack, cooperating fingers being provided for supporting the accumulated stack during elevating movement of the platform. Confining means for the patties and stack is disposed about and extends upwardly from the platform and the upper portion of this means is open upwardly to permit the insertion of a hand to grasp the stack and lift it upwardly and outwardly of the machine, and a further feature of the invention relates to the inserting and loading of the patties directly into a packaging cartonJ The production of a novel machine of this nature and for the purpose described comprises the primary object of the invention.

Another feature of the invention relates to novel mech-- anism for automatically removing each stack of patties from the machine and conveying it to a predetermined station when a predetermined number of patties have been elevated into a stack above said predetermined position. The production of an automatic stacking machine embodying this feature comprises a further object of the invetnion.

These and other features of the invention will be best understood and appreciated from the following description of preferred embodiments thereof selected for purposes of illustration and drawings in which:

Fig. 20 is a perspective view illustrating the first step in placing a carton on the machine in position to receive a stack of patties thereinto,

' Fig. 21 illustrates the carton in such position on the machine, and

Fig. 22 illustrates the filled carton being removed from the machine.

The machine .is mounted on a base 10 supported in line the inclined position of Fig. 2 by supports 12 resting on the shelf 14 of a table 15. The operating mechanism for the stacker, including a motor 16, is housed on the base V-belt 26.

Supported on and above the base 10 by posts 28 is a Mounted to reciprocate longitudinally in a bearing 32 on the plate is a plunger 34. An anti-friction roller 36 on the bottom end of the plunger engages the periphery of a cam 37 fixed to the shaft 20 and a compression spring 38 on the plunger normally holds the roller in contact with the cam. -Mounted on the top end of the plunger above the bearing 32 is a platform 40 adapted to be reciprocated up an down at each rotation of the shaft.

The machine as illustrated is constructed to cooperate with a hamburg patty making machine and'is adapted to receive and stack the patties as they slide by gravity down an inclined chute. This chute is shown at 41 'in Fig. 2 and pivoted at 42 to its bottom end is a lowermost portion 44. The free end of this portion is bifurcated to engage and move with the platform 40 as illustrated at 45 in Fig. 2. As thus constructed the patties slide down the chute and onto the platform.

Mounted on the plate 30 and having a pivoted finge 46 extending upwardly through a slot 47 in the platform 40 is a normally open micro-switch 48. The switch is in circuit with a solenoid 50 which is energized when the switch is closed by a patty sliding down the chute and into pivoting contact with the finger. Such closing of the switch trips mechanism, now to be described, for causing one rotation of the shaft 20. g

Directly adjacent to the cam 37 on and fixed to the shaft 20 is a collar 52 having a radial arm 54. A

clutch pin 56 is supported and mounted to slide in opposite directions in aligned holes in the cam and arm to two extreme positions. In one position (Fig. 2) one end of the pin is disposed in the path of movement of two diametrically opposed lugs 58 carried on the pulley 24 and in which position the other end of the pin clears a stop 60 fixed to the base. A compression spring 62 on the pin between the arm 54 and an annulus 63 fixed to the pin normally maintain the pin in this position. In its other extreme position (Fig. 2a) the pin overlaps the-stop 60 and clears the lugs 58.

Pivotally mounted on a post 64 integral with the base 10 and bearing 22 is a lever 65 (Fig. A tension spring 66 connected to the shorter arm of the lever and to a fixed pin 68 normally pivots the longer arm of the lever upwardly. A pin 69 on the free end of the lever extends through a vertical slot .70 in a bracket 72 carried on the base, the top end of. the slot providing a stop limiting upward travel of the pin and lever. The intermediate portion of the lever is semicircular and has an integral cam surface 74 disposed to cooperate with the beveled portion 75 of the annulus 63. The lever is normally in the raised position of Fig. 5 wherein contact of the annulus 63 with the plane portion 77 of the lever holds the pin.56 in the retracted position of Fig. 2a. In such position the pin is clear of the lugs '58 in the constantly rotating pulley 24.

The spring 66 normally maintains the lever 65 in the raised position of Fig. 5 with the pin 69 at the top end of its travel in the slot 70, and a sear 76 pivoted at 78 normally limits downward movement of the lever and pin. The armature 80 of the solenoid 50 is normally in the .raised position of Figs. 5 and 6 and in which position a conical portion 81 thereon forms a stop for the sear. A spring.82 normally pivots the sear to the stop position of Fig. 6 wherein the sear is disposed in stop position beneath the pin 69. Extending horizontally outward from the armature 80 above its conical portion 81 and through a vertical slot 83 in the bracket 72 is a horizontal arm 84. Energizing of the solenoid is adapted to draw the armature downwardly and pivot the sear out of the path of movement of the pin 69, and such downward movement of the armature also functions through the arm 84 to pull the pin 69 and lever 65 downwardly.

In the normal operation of the machine, the pulley 24 is constantly rotated and the clutch pin 56 is retracted to the position of Fig. 2a wherein it is engaged against the stop 60. When a patty 85 slides down the chute 41-44 and onto the platform 40, its forward end engages and pivots the trigger finger 46 to a position closing the switch 48. The solenoid 50 is thereupon energized and draws its armature 80 downwardly, thereby pivoting the sear rearwardly from beneath the pin 69 and pivoting the cam lever 65 downwardly away from the annulus 63. The spring 62 thereupon shifts the pin 56 to the position of Fig. 2 whereupon one of the lugs 58 contacts the pin and rotates the shaft 20 with the pulley 24. Such rotation continues until the annulus 63 again comes into contact with the cam 74, which has returned to the raised position of Figs. 5 and 6. The cam thereupon functions to retract the clutch pin 56 to the position of Fig. 2a and wherein the clutch pin comes into contact with the stop 60. The shaft 20 has thereupon been rotated one full turn when it is brought to rest against the stop 60.

Such full turn rotation of the shaft 20 and its cam 37 elevates the platform 40 and patty 85 thereon to the extreme top position illustrated in Fig. 11 and the platform then returns to the original position of Fig. 2. Two opposite sides of the platform are slotted at 86 to receive the fingers 88 on two levers 89 pivoted at 96, the retaining walls 91 about the elevator shaft being perforated at 92 to permit passage theretlrrough of the fingers. The levers have two inwardly extending arms 93 slotted at 94 to receive a pin 95 carried on the top end of a plunger 96 extending through a guide bearing 97. A compressionspring 98 on the plunger normally maintains an anti-friction roll 99 on the bottom end of the plunger in contact with a cam 100 fixed to the shaft 20. Rotation of the shaft and cam is adapted to move the fingers outwardly and inwardly synchronously with the platform movement as illustrated in Figs. 8 and 10.

As the platform and patty thereon are moved upwardly the cam 100 pivots the fingers outwardly to a position (Fig. 10) permitting the platform and patty to pass upwardly to the extreme top position of Fig. 11. Immediately following such passage the cam permits the fingers quickly to return to the position of Fig. 11 whereupon the patty is supported on the fingers as the platform drops to its original position. The next patty is elevated in like manner, the fingers continuing to support the prior elevated patties in top position during each patty elevating interim. As each elevated patty approaches the stack 102 (Fig. 10) the fingers are quickly moved outwardly and the elevated patty is added to the bottom of the stack.

The patty elevating operations are repeated, as illustrated in Figs. 7-13, and in Figs. 1-14 we have illustrated means including an endless conveyor 104 for automatically removing each patty stack when a predetermined number of patties have been accumulated. Disposed to cooperate with the top end of the conveyor, along the lower margin of the platform 40 in its topmost position (Fig. 14), is a gate. 105 pivoted at 106, a spring 108 normally holding the gate in the raised position of Fig. 7. A U-shaped pusher 110 is disposed at the opposite margin of the platform and is supported to slide on guide rails 112. A lever pivoted at 114 has an upwardly extending arm 115 connected to the pusher at 117 and a downwardly extending arm 119 carrying an anti-friction roll 121 disposed in the path of movement of a cam 123 on a gear 125, a spring 127 normally holding the pusher retracted to the position of Fig. 2. The gear is rotatably mounted on the base 10 and is driven by a pinion 129 fixed to the shaft 20. Passage of the cam beneath the roll is adapted to swing the lever to the broken line position of Fig. 2 and push the accumulated stack of patties onto the conveyor. During such operation the pusher also contacts and swings the gate 105 downwardly to the position of Fig. 14 wherein it serves as a bridge to the conveyor. As illustrated in the drawings, the machine automatically removes each stack of four patties and the number of patties thus removed in each stack can be varied as by changing the gearing ratio.

In Figs. 15 and 16 we have illustrated a modified construction particularly adapting the patty stacks to be removed manually. This construction includes a confining housing 131 for the patties extending upwardly about the elevator shaft and platform 40. The housing is cut away and open upwardly at 133 from the predetermined position at the bottom of the stack to a width confining the patties and permitting a hand to extend through the opening and grasp and lift upwardly and outwardly a stack of accumulated patties, as indicated in Fig. 16.

The patty stacks can be placed in any arrangement most convenient for their disposal and in Figs. 20-22 we have illustrated the packaging of the patties directly into cartons 135. In this case the patty stack receiving housing 131 (Fig. 16) is constructed as illustrated in Fig. 21 wherein one of the corner posts 131 is cut away to provide a stop 137 and the other corner post 131 (Fig. 21) serves as a guide for locating the carton in patty receiving position.

Briefly, this method of packaging the stacked patties directly into cartons is as follows. The operator grasps an empty carton in his right band (Fig. 20) with the lid 139 open and the open side of the carton facing downwardly. He transfers this carton to his left hand and places it in position on the machine to receive the stacked patties (Fig. 21). In this operation a corner of the carton is' placed within the corner post 131', thus locating the carton laterally with its open face disposed downwardly in position to receive the patties thereinto, and the carton is seated on the stop 137, thus locating the carton vertically in patty receiving position. Ordinarily, four to six patties will be packaged within each carton and, when the desirednumber of patties is disposed within the cazton, the operator slides his fingers in supporting position therebeneath and lifts the carton and contained patties from the machine (Fig. 22) and places them in upright position on a tray or conveyor for completion of the packaging.
