  • a plurality of flags 131 are mounted on corresponding brackets 132 on turntable 12 (see also Figure 8) and cooperate with photocell-photodetector pairs 129 in a manner similar to that described above for optical switch assembly 124.
  • flags 131 depend downwardly from turntable base 100, together with single control flag 130, and in this embodiment, the two pairs or sets (not shown in Figures 2 and 3) are also mounted on support wall 113 behind gripper 110.)
  • Flags 131 cooperate with optical switch arrangement 127 to provide indexing of the turntable 12.
  • a pair of signals is produced by each flag 131 as that flag passes between the photodiode and photodetector of the pairs or sets 129, and that when a flag 131 is positioned at a location between the pairs 129, so that no signal is produced but so that a signal will be produced if the turntable rotates in either direction, precise positioning of the turntable 12 is achieved.
  • an inverted U-shaped mounting support or upright 62 including a support bracket 62a, supports the downwardly depending pneumatic cylinder 64 which, in turn, controls the movement of an associated plunder head 64a down into the upper, open end of a canister 14 to force the contents of the canister out through the dispensing nozzle assembly 104.
  • the plunger assembly 64 bay not be required in dispensing all of the ingredients to be mixed in a particular batch, and would not, for example, be used in dispensing thinners and the like. It will be appreciated that whether or not the plunger assembly 64 is used in dispensing a particular ingredient or component to be mixed is controlled by the operator and, in a fully automated operation, is programmed into the system commands.
  • Figure 13 shows a follower plate 132 which is adapted to cooperate with the plunger head or piston 64a as the latter is caused to move downwardly into a canister 14.
  • the basic purpose of follower plate 132 is to prevent leakage of ink from the top of a canister 14, especially during the application of pressure by plunger 64a.
  • the follower plate 132 comprises an upper plate 134, preferably made of a metal such as aluminum and including an outer peripheral ring 135 (preferably made of polytetrafluoroethylene) which engages the side walls of the associated canister 14 to provide sealing, an intermediate rubber platelike member 136, which also engages the side walls of the associated canister 14, and a bottom plate 138, also preferably of metal such as aluminum, all secured together by a central screw 140.
  • the diameter of the bottom plate 138 is substantially less than that of the rubber plate 136 so that the former does not extend to the wall of the canister 14.
  • follower plate 132 prevents the piston 64a from directly contacting the ink in the canister 14 and thus keeps the piston 64a clean.
  • the screw 140 in the middle of follower plate 132 permits the follower plate 132 to be removed from the canister when the latter is empty, using a special tool (not shown).
  • an important feature of the invention involves the use of a two-step full open/partial open valve actuation sequence, in the nature of a "dribble" feed, so as to achieve the required weighing accuracy.
  • the basic sequence is to fully open the valve for an initial dispensing period, to then partially close the valve (e.g., to a position where the valve is one-quarter open) and then to fully close the valve.
  • the times during which the valve is fully open and partially open can be preprogrammed depending on the type of ink or other ingredient to be dispensed.
  • FIG 14 is a block form electrical circuit diagram of the overall control system, and to Figures 15(a), 15(b) to Figures 19(a), 19(b) which show the sequence of steps employed in the dispensing operation.
  • control panel 103 also shown schematically in Figure 4
  • control modules are provided which include a gripper control module 144 and three valve control modules 146, 148 and 150, which serve to control the dispensing operation.
  • Other control modules include a pair of motor control modules 152 and 154, a "master index" module 156 and a piston control module 158.
  • control signals are transmitted from CPU 24 to the gripper control module 144 for the gripper mechanism 110 to first control engagement thereof with control valve actuator 106 for valve actuator assembly 104 and thereafter, in sequence, to valve control modules 146, 148 and 150 to provide the required rotation of valve actuator 106 needed to first provide opening of the valve, to then provide partially closing thereof and to finally provide full closing thereof, as mentioned above and as is described in more detail below.
  • cam 160 and 162 are provided which rotate with the gripper 110 and which include notches or slots in preset angular positions around the periphery therein that cooperate with microswitch activating cam followers to signal that the gripper 110, and thus the ball valve 120 of valve assembly 104, have both been rotated to the desired position.
  • cam 160 includes notches 160a and 160b which cooperate with respective cam followers 164a and 166a of microswitches 164 and 166, respectively positioned at angularly spaced locations around the periphery of cam 160.
  • microswitches 164, 166 and 168 are also schematically illustrated in Figure 13, and, as indicated, microswitch 164 signals that the valve 120 is in the proper "fully open” position, microswitch 166 signals that the valve is in the proper "one-quarter open” position and microswitch 168 signals that the valve is in the proper "fully closed” position.
  • cams, cam followers and microswitches described above is provided to ensure precise positioning of the valve, and to thus ensure that the desired amount of ink is dispensed, and that this arrangement can be dispensed with if the precise positioning of the valve can otherwise be provided, e.g., by the gripper controller.
  • Figures 15(a), 15(b) to Figures 19(a), 19(b) which illustrate an embodiment similar to that of Figure 8, but employing, as noted above, a gripper 170 having jaws that open and close to engage the actuator 106 of valve assembly 104.
  • a gripper of this type is the precision gripper made by Barrington Automation while the pneumatic actuator can be of the type made by Worcester (39/40 series).
  • FIG. 15(a) and 15(b) the system is shown in the rest position thereof wherein gripper 170 is open and valve 120 of valve assembly 104 is fully closed.
  • gripper 170 is closed responsive to a signal from gripper module 144 ( Figure 13), so as to engage valve actuator 106.
  • a signal from module 146 causes the actuator 106 to be turned (e.g., clockwise in the exemplary embodiment under consideration) to the fully-open position.
  • cam follower 164a drops into notch 160a in the periphery of the cam 160 and in doing so activates microswitch 164 thereby producing an output signal which terminates rotation of the gripper 170.
  • the time during which the control valve 120 of valve assembly 104 is maintained in the fully opened position thereof is a function of a number of factors including the nature of the ink being dispensed (e.g., viscosity, etc.), and as indicated in Figure 14, the weight of the ink that has been dispensed is determined by load cell or scale 20.
  • the weight value at which the valve opening is changed from fully open to partially open is determined in calibrating the system and is 90% of the expected weight in the exemplary embodiment under consideration.
  • the second microswitch 166 is activated during this time sequence, when the gripper 170, and thus valve actuator 106, is precisely rotated to the partially (25%) closed position, at which time the signal produced by microswitch 166 acts through computer 26 to terminate gripper rotation.
  • valve control module 150 When the amount of ink dispensed into the blend can 18 as determined by weigh scale 20 reaches the desired level (e.g., 97% of the expected weight), a signal from CPU 26 to valve control module 150 will cause gripper 170 to be rotated back to the fully-closed position. As indicated in Figures 19(a) and 19(b), the third microswitch 168 is activated when the valve actuator 106 is rotated to the precise, predetermined fully closed position so as to terminate rotation of the gripper 170. When this is accomplished, the jaws of gripper 170 are caused to open by a signal from the CPU 26 so that the system is returned to the rest state shown in Figures 15(a) and 15(b) and is thus readied for the next ingredient.
  • the desired level e.g. 97% of the expected weight
  • Tilting assembly hydraulic lifter 38 basically comprises a hinged plate 180 which is raised (as indicated in dashed lines) or lowered (as indicated in solid lines) in a controlled manner by extension and retraction of a hydraulic control arm 182 under the control of a hydraulic controller 184, to thereby provide controlled pouring from blend can 18.
  • mixer unit 36 Prior to dispensing the contents of blend can or ink pot 18, mixer unit 36 (referred to above in connection with Figures 1 and 4) is used to thoroughly mix and blend these contents.
  • a motor 186 and drive unit 188 are mounted on a base 190 by a hydraulic lift device 192 which enables the motor 186 and drive unit 188 to be raised and lowered relative to the base 190.
  • Drive unit 188 drives a stirrer assembly 194 comprising a stirrer rod 196, which is detachably or removably attached to the rotary drive output shaft 188a of drive unit 188 by an arrangement comprising a pin 196a and an L-shaped slot 188b, as illustrated, and a flexible blade 198, preferably fabricated of polytetrafluoroethylene, which is adapted to be inserted into an ink pot or blend can 18.
  • Ink pot 18 is removably secured to base 190 by an arrangement including a shaped notch 18a in a skirt 18b formed on the bottom of ink pot 18 and a pin 190a provided on an upstanding support pad on which ink pot 18 is supported and around which skirt 18b extends.
  • mixing unit 36 is operated at low speed, not greater than 60 rpm, in that this provides substantially improved mixing. It is to be understood that mixer 36 and hydraulic lifter assembly 38 can be integrated into a single unit wherein the ink pot 18 would be removably secured to the upper plate 180 of assembly 38. However, in a presently preferred embodiment, the units are separate, as indicated schematically in Figure 4, so that the different operations, i.e., mixing and tilting, can take place at the same time using two different ink pots.
  • the computer 26 also stores an ingredient database which includes for each choice of the ingredients contained in the canisters 14, the ingredient code, name and hazard code, as well as data relating to the dribble point, cutoff point, accuracy percentage, cost and the like.
  • a formula database includes the formula name and code, the ingredients in per cent, quality control specifications, manufacturer's instructions and the like.
  • the operator inputs appropriate data in computer 24, including the formula number, name option, quantity (e.g., in kilograms), finished product container code, operator number, the customer's name and the date.
  • the computer will generate a batch number and a ticket reading (including all inputs) and will display the formula by weight and record the starting time. It will be understood that after the operator input page is completed, all of the ingredients will be displayed on a batch display page.
  • the batching procedure then starts with checking operations based on interaction with the database described above. By simply hitting the correct keys, the operator initiates weigh up operation which is then carried out automatically.
  • the basic weigh up operation has been described above and begins with movement of a canister 14 containing one of the selected ingredients to the dispensing station 16.
  • the computer 26 will determine the shortest route to dispensing station 16, i.e., whether clockwise or counterclockwise and, referring to Figure 14, will transmit a signal to either module 152 (clockwise) or module 154 (counterclockwise).
  • the selected module will then cause motor 88 to step the turntable or carousel 12 around the required angular distance or arc to the dispensing station 16.
  • the direction of movement of turntable 12 provided by motor 88 is controlled simply by reversing the direction of current flow through motor 88.
  • the "master index" module 156 in cooperation with optical switch 124 signals when a predetermined canister 14 arrives the dispensing station or arrives at a further reference point (e.g., in the embodiment of Figures 8 and 9) so that the computer 26 can calculate the position of the turntable 12 and determine the amount of rotational movement required to move a selected canister to the dispensing station 16.
  • the piston head 64a will exert pressure on the canister, as required. (In this regard, as mentioned above, some ingredients such as solvents do not require the use of piston assembly 64.)
  • the gripper operation then begins and as described in some detail above in connection with Figures 15(a), 15(b) to Figures 19(a), 19(b), the gripper 170 is first closed, and the valve 104 is fully opened.
  • the valve is partially closed, i.e., so as to be one-quarter open in the preferred embodiment.
  • the computer 26 Upon the completion of a dispensing operation for a first canister, the computer 26 will transmit a signal to cause the gripper 170 to open, and to cause the piston head 64a to be removed from the top of the canister 14. The turntable 12 will then be caused to rotate to bring the next canister 14 into registration at the dispensing station 16. The procedure will be repeated upon all ingredients of the selected formula have been dispensed.
  • the expected total weight will include the amount requested, the adjusted weight for strength compensation, and, typically, an additional 1.5% of the weight for loss compensation.
  • the operator can command a cost report from the computer which will then be printed out.
  • the ink mixture in ink pot 18 is at this time ready for mixing or blending using the mixing unit 36 in the manner described above.
