DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0026] With reference now being made to FIGS. 1-5, the new and improved automatic packaging dispensing system of the present invention is disclosed and is generally indicated by the reference character 100. More particularly, it is seen that the system 100 is adapted to dispense both packaging boxes and wrapping paper packaging and therefore comprises a packaging box sub-system 102 and a wrapping paper packaging sub-system 104. The packaging box sub-system 102 comprises a plurality of different types or sizes of packaging boxes that are disposed within different packaging box assemblies 106 which are fixedly mounted at their upper end portions upon a mounting plate 108 which is operatively connected to a linear belt drive 110 by means of a mounting bracket 112 disposed atop a linear slide block 114 which is connected to the linear belt drive 110. A reversible motor 116 is operatively connected to the linear belt drive 110 so that when the reversible motor 116 is actuated in a first mode for a predetermined amount of time, the linear belt drive 110 will move the mounting plate 108 and the plurality of packaging box assemblies 106 mounted thereon a predetermined distance in a first direction, whereas, when the reversible motor 116 is actuated in a second mode for a predetermined amount of time, the linear belt drive 110 will move the mounting plate 108 and the plurality of packaging box assemblies 106 mounted thereon a predetermined distance in a second opposite direction.
[0027] The mounting plate 108 undergoes its lateral, reciprocating movements as a result of being movably attached to, and supported upon, a horizontally oriented guide rail 118 as can be seen in FIGS. 1 and 2. In this manner, any one of the plurality of packaging box assemblies 106 can be moved so as to be properly positioned relative to, and beneath, a vacuum suction cup pickup and transfer assembly 120, which can be seen in FIG. 1 and which will be more fully discussed hereinafter, such that the vacuum suction cup pickup and transfer assembly 120 can remove the uppermost packaging box, one exemplary box 122 being disclosed within FIG. 5, disposed within the particular packaging box assembly 106 and thereby transfer the packaging box 122 to a food preparation line conveyor 124, as seen in FIG. 1, such that the particular packaging box may be moved to the next food preparation station of a food preparation line 126.
[0028] With reference now being made to FIG. 4, one of the packaging box assemblies 106 will be described. More particularly, it is seen that each packaging box assembly 106 comprises a box support platform 128 upon which a plurality of a particular kind or type of packaging boxes 122 are to be stacked so as to effectively form a packaging box magazine from which the uppermost packaging box 122 will be removed by means of the vacuum suction cup assembly 120. The box support platform 128 actually comprises a horizontally oriented component 130, upon which the stack of packaging boxes 122 are actually disposed and supported, and an upstanding bracket 132 to which a pair of laterally spaced constant force springs 134 are adapted to be attached although the springs 134 are not shown attached in FIG. 4. The springs 134 are mounted upon a horizontal spindle 136, the ends of which are mounted within laterally spaced end brackets 138. The end brackets 138,138, in turn, are connected to a peripheral framework 140 which is mounted upon the mounting plate 108 and to which are attached a plurality, for example, four, leaf-spring type fingers 142, as well as a pair of vertically oriented packaging box guide rods 144 which depend vertically downwardly from opposite sides of the peripheral framework 140.
[0029] The peripheral framework 140 and the vertical guide rods 144 are adapted to maintain the stack of packaging boxes 122 upon the stacking platform component 130, with the vertical guide rods 144 engaging corner regions 146 of the packaging boxes where are effectively defined between the upper or cover portion of the packaging box 122 and the bottom portion of the packaging box 122. The disposition of the vertical guide rods 144 within the corner regions 146 of the packaging boxes 122 effectively prevents the plurality of packaging boxes 122 from moving forwardly and backwardly as well as laterally from side to side. Furthermore, with reference being additionally made to FIG. 4a, it is seen that the upper end portions 141 of the vertical guide rods 144 are bent at an angle of 90 and are seated within slots 143 defined within the peripheral framework 140. Accordingly, the upper end portions 141 of the pair of vertical guide rods 144 may be moved within the slots 143 and relative to each other such that the distance between the pair of vertical guide rods 144 is rendered adjustable. In this manner, different packaging boxes 122, having different width dimensions, can be housed or accommodated within the packaging box assembly 106. It is additionally noted that mounting plates 145 are fixedly secured atop the peripheral framework 140 so as to securely fix the bent end portions 141 of the vertical rods 144 within the slots 143 of the peripheral framework so that, in turn, the pair of vertical rods 144 will remain at their relative desired spacing so as to house or accommodate differently sized packaging boxes 122.
[0030] Accordingly, it can be appreciated that as a stack of packaging boxes 122 are mounted upon the horizontal component 130 of the box support platform 128, the box support platform 128 will be moved downwardly and the constant force springs 134, when attached to the rear upstanding wall component 132 of the box support platform 128, will be extended such that the constant force springs 134 will continuously tend to move the box support platform 128 back toward its uppermost position so as to continuously move the box support platform 128 incrementally upwardly as the uppermost packaging box 122 is removed from the box support platform 128 by means of the vacuum suction cup assembly 120. The box support platform 128 moves vertically downwardly and upwardly along a vertically oriented guide rail 146 which is fixedly secured at its lower end to a mounting bracket 148. The plurality of fingers 142 extending into the central part of the peripheral framework 140 supply a sufficient retaining force to the stack of packaging boxes 122 disposed upon the horizontal component 130 of the packaging box platform 128, however, when the uppermost packaging box 122 is removed by means of the vacuum suction cup assembly 120, the plurality of fingers will flex upwardly, permitting the uppermost packaging box 122 to be withdrawn from the stack of packaging boxes 122 disposed upon the horizontal component 130 of the packaging box platform 128, and will effectively slide along the external surface portions of the uppermost packaging box 122 being withdrawn by means of the vacuum suction cup assembly 130 until the fingers 142 snap back to their original positions, thereby preventing any further packaging boxes 122 from being removed from the packaging box assembly 106. It is lastly noted that the packaging box assembly 106 also includes a packaging box sensor 152 which is adapted to be coaxially aligned with an aperture 154 defined within the horizontal component 130 of the packaging box platform 128. In this manner, in a manner similar to a photocopying machine warning the user that the supply of paper in the paper tray has been depleted, the sensor 152 will sense when the last packaging box 122 has been removed from the packaging box assembly 106 whereby the supply of packaging boxes 122 needs to be replenished.
[0031] Continuing further, and with particular reference being made to FIGS. 6 and 7, the vacuum suction cup pickup and transfer system 120 will now be described. A pair of suction cups 154 are fixedly attached to the bottom surfaces of a pair of vacuum manifolds 156 so that the system comprises four suction cups 154. Each one of the vacuum manifolds 156 is fluidically connected to a vacuum generator 158, and the vacuum generators 158,158 are fixedly mounted upon a horizontally oriented mounting bracket 160. A plurality of vertically oriented tubes or guide rods 162 have their lower ends fixedly connected to the mounting bracket 160 and are operatively associated with a servo unit 164 which is fixedly mounted upon a vertically extending housing 166. Accordingly, as the plurality of tubes or guide rods 162 move relative to the servo unit 164, the plurality of suction cups 154 will accordingly be moved upwardly and downwardly. It is to be noted at this juncture that the control of all movable components, the operation of all valving, not necessarily shown, and the like, comprising the automatic packaging dispensing system 100 are under the control of a suitable control unit which may be, for example, a programmable logic controller 168 schematically illustrated within FIG. 1, which causes the various operative components to act as described in accordance with patron order data transmitted thereto from the point-of-sale (POS) location.
[0032] Continuing further, it is also seen that the vertically oriented housing 166 is fixedly mounted upon a mounting plate 170 and that the mounting plate 170 is fixedly connected to a servo unit 172 which, in turn, is slidably movable upon a linear slide 174. Accordingly, when the servo unit 172 moves along the linear slide 174, it will cause the suction cup assembly, comprising the mounting plate 170, the housing 166, the tubes 162 and the servo unit 164, and the mounting bracket 160, the vacuum generators 158, the vacuum manifolds 156, and the vacuum suction cups 154 to move laterally toward the left or right as viewed within FIGS. 6 and 7, or to move into or out of the page as viewed within FIG. 1. In a similar manner, the servo unit 164 can effectively cause the tubes or guide rods 162 to move upwardly and downwardly so as to, in turn, cause the mounting bracket 160, the vacuum generators 158, the vacuum manifolds 156, and the vacuum suction cups 154 to move upwardly and downwardly. Accordingly, when these compound movements are properly controlled and timed by means of, for example, the programmable logic controller (PLC) 168, the vacuum pickup and transfer assembly 120 can be moved to a position whereby the plurality of vacuum suction cups 154 will be disposed above a selected one of the plurality of packaging box assemblies 106 which has been moved into position beneath the vacuum suction cups 154 of the vacuum pickup and transfer assembly 120 by means of the linear belt drive 110, the vacuum control generators 158 can then be actuated, and then the servo unit 164 can be actuated so as to move the vacuum suction cups 154 downwardly such that the vacuum suction cups 154 can remove or extract the uppermost one of the packaging boxes 122 from the selected one of the plurality of packaging box assemblies 106. The servo unit 164 can then be actuated so as to elevate the packaging box 122 that has been removed or extracted from the selected packaging box assembly 106, the servo unit 172 can then be actuated so as to effectively retract the vacuum suction cup assembly from its forwardmost position above the selected one of the plurality of packaging box assemblies 106 to a predetermined rearwardmost position at which the vacuum suction cups 154 will now be disposed above the food preparation line conveyor 124. The servo unit 164 can then be actuated again so as to lower the vacuum suction cups 154 toward the food preparation line conveyor 124, and when the vacuum suction cups 154 are disposed immediately above the food preparation line conveyor 124, the vacuum generators 158 can be deactivated whereby the packaging box 122 will be released from the vacuum suction cups 154 and deposited onto the food preparation line conveyor 124.
[0033] With reference now being made to FIGS. 8-12, the wrapping paper packaging sub-system 104 will now be described. More particularly, it is seen that the wrapping paper packaging sub-system 104 comprises a wrapping paper packaging housing 176 within which there is disposed a plurality of horizontally oriented, vertically spaced trays 178, each one of the trays 178 holding a predetermined number of wrapping paper packaging sheets, and wherein each tray 178 holds a different type or size of wrapping paper packaging sheet. An L-shaped angle iron or angle bracket 182 has its long leg fixedly secured to the rear wall 183 of the housing 176 while the short leg of the L-shaped angle iron or angle bracket 182 is fixedly secured to a slide block 180 which is part of a vertically oriented linear ballscrew actuator 184 which is driven by means of a suitable motor 186, all of which can best be seen in FIG. 9. In addition, it is seen that the vertically oriented ball screw actuator 184 is also fixedly mounted upon a vertically oriented mounting platform or wall 188 which is also shown transparently within FIG. 10 for clarity purposes.
[0034] As can best be seen in FIG. 11, the rear wall 183 of the housing 176 is integrally connected to a left wall 190 of the housing 176 from which project a pair of vertically oriented, laterally spaced female track members 192 which are adapted to engage and slide along a pair of vertically oriented, laterally spaced male guide rails 194. In this manner, as the wrapping paper packaging housing 176 is moved vertically upwardly and downwardly by means of the linear ballscrew actuator 184, the movement and support of the wrapping paper packaging housing 176 is provided by means of the operatively cooperative track members 192 and guide rails 194. It is lastly noted, as can also best be seen in FIGS. 10 and 11, that a vertically oriented rail 193 is mounted upon the left wall 190 of the housing 176, while a pair of pneumatic brake components 195,195 are mounted upon the mounting platform or wall 188 so as to be disposed upon opposite sides of the vertically oriented rail 193. These pneumatic brake components 195,195 are provided, and are adapted to be moved toward each other so as to fixedly grasp opposite sides of the vertically oriented rail 193, so as to prevent the entire wrapping paper packaging housing 176 from falling, for example, power to the motor 186 and the linear ballscrew actuator 184 should be terminated for some reason, such as, for example, a power switch or circuit breaker has been tripped, or the like.
[0035] With reference still being made to FIG. 11, it is further seen that each tray 178 is also slidable upon horizontally oriented ball-bearing slides or tracks 196 which extend from the rear wall 183 of the housing 176 toward the front of the housing 176, which is open so as to permit the front edge portions of the plurality of trays 178 to project outwardly therefrom, so that the trays 178 can be easily and readily moved from their normal positions disposed internally within the tray housing 176 to external positions relative to the tray housing 176 when packaging sheets within a particular one of the trays 178 need to be accessed by means of the vacuum suction cups 154 of the vacuum pickup and transfer assembly 120. Each forward end of each wrapping paper tray 178 is provided with a horizontally oriented finger 198, and a horizontally oriented tray extension piston-cylinder assembly 200 is mounted upon the external surface of the vertically oriented mounting platform or wall 188 such that when the piston of the piston-cylinder assembly 200 is extended, the piston will encounter the finger 198 of a particular wrapping paper tray 178 and thereby cause that particular tray 178 to be moved out from the interior of the paper tray housing 176 to an external position at which the vacuum suction cups 154 of the vacuum pickup and transfer assembly 120 can engage the uppermost wrapping paper sheet within that particular wrapping paper tray 178 and then transfer that wrapping paper sheet to the food preparation line conveyor 124.
[0036] More particularly, it is to be noted that the distal end of the piston of the piston-cylinder assembly 200 is provided with a head portion 202 which has a slotted section 204, which can be seen in FIG. 11, through which the various fingers 198 of the various paper trays 178 can pass as the paper tray housing 176 is moved upwardly or downwardly, however, when the paper tray housing 176 has been moved upwardly or downwardly such that a particular one of the paper trays 178 is located at the correct position for that particular tray 178 to be moved out from the housing 176 such that the wrapping paper packaging sheets disposed within that tray 176 can be accessed, the finger 198 of that particular paper tray 178 will be disposed within the slotted section 204 defined within the head portion 202 of the piston of the piston-cylinder assembly 200 such that when the piston-cylinder assembly 200 is actuated, the head portion 202 of the piston of the piston-cylinder assembly 200 can act upon the finger 198 of that particular paper tray 178 so as to move that particular paper tray 178 outwardly from the paper tray housing 176 whereby the uppermost wrapping paper packaging sheet disposed within that extended tray 178 can now be grasped by means of the vacuum suction cups 154 of the vacuum pickup and transfer assembly 120.
[0037] With reference again being made to FIG. 1, a wrapping paper packaging sheet sensor 206 is mounted at a location upon the food preparation line 126 that is adjacent to and disposed above the wrapping paper packaging housing 176 such that when a selected paper tray 178 of the wrapping paper packaging housing 176 is extended outwardly from the wrapping paper packaging housing 176 such that the uppermost wrapping paper packaging sheet disposed within the selected paper tray 178 can in fact be grasped by means of the vacuum suction cups 154 of the vacuum pickup and transfer assembly 120 and transferred to the food preparation line conveyor 124, the wrapping paper packaging sheet sensor 206 can determine the vertical distance to the uppermost wrapping paper packaging sheet disposed within the selected paper tray 178. It is to be appreciated that this distance will vary as the supply of wrapping paper disposed within a particular paper tray 178 is steadily depleted. Accordingly, the sensor 206 will transmit a signal to the vacuum pickup and transfer assembly 120 such that, for example, the tubes and servo system 162,164 will know precisely how far to move the plurality of suction cups 154 downwardly in order to properly engage and extract the uppermost wrapping paper sheet disposed within the extended paper tray 178.
[0038] Lastly, as can best be appreciated from FIGS. 11 and 12, each paper tray 178 is seen to have a substantially rectangular configuration so as to house or accommodate the various different wrapping paper packaging sheets. Accordingly, in order to permit any one paper tray 178 to house or accommodate any particularly sized wrapping paper packaging sheet, a pair of adjustable guides 208,210 are respectively slidably mounted within a pair of guide slots 212,214, all located upon two sides of each paper tray 178 which form a corner section 216 of the paper tray 178. Set screws 218,220, or the like, are mounted within the adjustable guides 208,210 so as to fix the adjustable guides 208,210 at desired positions according to the particularly sized wrapping paper packaging sheets to be accommodated or housed the particular paper tray 178. Such guides 208,210, guide slots 212,214, and set screws 218,220 are similar to those components conventionally utilized within photocopying machines for accommodating or housing differently sized photocopy paper sheets such as, for example, letter sized paper or A4 international sized paper. Still yet further, each paper tray 178 is provided with a through-hole 222 to permit, for example, a light beam or other sensor signal to pass therethrough so as to indicate that the supply of wrapper paper packaging sheets, disposed within the tray 178, has been depleted, such a sensing system again being similar in operation to a paper supply sensor system incorporated within a photocopying machine.
[0039] Obviously, many variations and modifications of the present invention are possible in light of the above teachings. For example, in lieu of, or in conjunction with, the Point-of-Sale (POS) location, the overall system 100 can also include a user interface where patrons can enter their orders whereupon the rest of the system 100, as controlled by means of the programmable logic controller (PLC) 168, will automatically dispense the properly required food item packaging. Still further, a brake can be operatively associated with the box support platform 130 so as to ensure that the support platform 130 is fixedly held against the vertically oriented guide rail 146 at a predeterminedly elevated position, the brake being released when the constant force springs 134 are to move the platform 130 upwardly toward the suction cups 154. The brake effectively works in combination with vacuum sensors which will effectively confirm that sufficient vacuum is being provided to the suction cups 154 and that the platform 130 is to be maintained at its predetermined elevation so as to enable the suction cups 154 to remove the uppermost packaging box 122.
