Definitions

  • a dispensing system for dispensing predetermined quantities of a fluent material onto moving material receiving surfaces.
  • the system includes a dispensing valve having a shutoff valve and an oscillated dispensing member.
  • the shut-off valve and the dispensing member are actuated by air cylinders controlled by an electric timing circuit responsive to a sensing element which senses the approach of a material receiving surface.

  • the present invention is directed to the dispensing art and, more particularly, to an improved apparatus for dispensing variable amounts of fluent material at predetermined time intervals.
  • the invention is especially applicable for dispensing batters in baking pans and will be described with particular reference thereto; however, it will be appreciated that the invention is capable of broader application and could be used to dispense a wide variety of material into or on any type of receiving surface or container.
  • the present invention overcomes the above problems and provides a dispensing system which can handle a variety of types of batters and can be readily adjusted to automatically dispense substantially any desired quantity into any size or shape of pan automatically.
  • the system is arranged so that it can be readily moved from one production line to another, thus facilitating its use for a variety of separate operations.
  • an improved dispensing system for use with a conveyor adapted to convey a plurality of material receiving surfaces past a selected location at a predetermined fixed speed.
  • This system includes an adjustable dispensing valve means adapted to be positioned above the conveyor at the selected location.

  • An adjustable timing means responsive to the signal is provided for causing the dispensing valve means to dispense a predetermined amount of material after a predetermined time period.
  • selectively operable adjustable timing means are provided for causing the dispensing valve to dispense additional quantities of material at predetermined time intervals following the dispensing of said first quantity.
  • the system can be utilzed for dispensing into a variety of pan sizes and with conveyors which move at a variety of different speeds.
  • the setting for the the first timing means depends on the distance from the sensor to the desired location and the speed of the conveyor. If a conveyor of relatively high speed is used then the first timer is adjusted for a relatively short time delay because the time it takes the pan to travel from the sensor to a position beneath the dispensing valve is relatively short. Additionally, by varying the time delay period slightly, the material can be deposited at any loca tion in the pan.
  • the second selectively operable adjustable timing means permits the system to be used for filling pans such as cupcake pans or a group of pans mounted in a common frame, or for making a plurality of spaced deposits in a single pan. Note that by adjusting the second timer the depositing valve is caused to dispense additional quantities of material at spaced intervals following the first deposit. Thus, in response to a single pan being sensed the dispensing valve can be caused to dispense a desired number of deposits at any desired time interval.
  • an improved dispensing valve for dispensing predeterminde quantities of fluent material.
  • This dispensing valve comprises an elongated valve body having an upper portion and a lower portion.
  • a longitudinally extending chamber is formed in the body and is communicated with a supply of material to be dispensed by a longitudinally extending materal receiving opening formed in the upper portion of the body.
  • An elongated material outlet opening is formed in the lower portion of the body. and is opened and closed by an elongated rotatable shut-off valve member positioned in the chamber adjacent the outlet.
  • a dispensing member is also positioned in the chamber and extends longitudinally thereof. This member is mounted for oscillation between a material receiving position and a material dispensing position.

  • a conventional conveyor belt 18 is driven by rollers 20 which extend between members 16.
  • Conveyor belt 18 is moved at the desired rate through a variable speed motor 22 mounted at the left hand end of the conveyor and connected with the left roller 20' through a sprocket 24 suitably secured to the end of the motor drive shaft and connected by a chain 26 to a second sprocket 28 keyed or otherwise connected to the roller shaft.
  • Depositing valve C includes a main valve body 30 which supports material hopper 34 connected to the top of the valve body through a wedge lock connector arrangement 37. As best shown in FIGURE 3, this arrangement comprises a wedge bar 31 connected to the top of the valve and cooperating with a wedge surface formed on the hopper. The hopper is forced against the wedge bar 31 and thus into snug engagement with the top of the valve by an arm 33 which is pivotally connected at its lower end to the valve body, and at its upper to the hopper.
  • the pivot hole in the upper end of the arm is of oblong shape and arranged so that as the arm 33 is moved counterclockwise a force directed downwardly and to the left is applied to the hopper to cause it to move against the wedge bar 31 and the top of the valve.
  • a bolt or stud 35 is connected to the valve and extends loosely through arm 33 where it is engaged by a wing nut to provide means for locking the hopper in position.
  • main valve body and hopper 34 are supported in cantilever fashion by a pair of support arms 32 which extend from the drive housing 41. By supporting the valve and hopper in this manner, they can be readily moved into position over any desired conveyor.
  • Depositing valve C and drive assembly D are mounted on a main base frame 35 provided with casters 36. This arrangement permits this portion of the assembly to be readily moved from one production line to another to permit the apparatus to be used for a variety of different operations.
  • the height of the depositing valve is adjustable in any convenient manner such as link assembly 39. Additionally, other methods of varying the height :of the depositing valve readily suggest themselves.

The opposite ends of the housing are closed by end plates 42 and 44 releasably secured thereto by screws 46.
  • An inlet opening is provided in the upper portion of the body to permit the batter or other material to flow from the hopper into the chamber.
  • a longitudinally extending outlet opening 48 is formed along the bottom portion of the body to permit the material to flow therefrom into the pan or other receiving surface positioned beneath the valve.
  • a die or orifice plate 50 is held in the outlet opening by the releasable clamp mechanism 52.
  • this releasable clamp arrangement comprises two rods 49 which are mounted on opposite sides of the valve and spaced therefrom.
  • a plurality of clamp arms 51 are freely pivotal and slidable on the left rod (as viewed in FIG.
  • dispensing valve C must be capable of dispensing exact amounts of batter without undue working or damage to the batter, it is provided with a unique shut-off and dispensing mechanism.
  • This mechanism comprises a cut-off valve member 54, positioned longitudinally of the body 30 and having a reduced end portion mounted in suitable bearings in the end plate 42. The opposite end likewise has a reduced portion 62 which extends through end wall 44 and provides means for rotating the valve element 54.
  • the valving surface of valve element 54 is of cylindrical configuration and arranged to fit closely with a similarly shaped valve seat formed along outlet slot 48.
  • the die 50 is shaped on its upper surface to conform closely to the configuration of the valving surface of element 54. This arrangement permits the valve to close off the flow of batter from the valve chamber with a clean, sharp, non-drip cut-off point.
  • the means for dispensing the desired amount of batter through the outlet opening 48 comprises a centrally positioned shaft 56 having reduced end portions 64 mounted in suitable bearings formed or mounted in end plates 42 and 44.
  • Shaft 56 is preferably positioned to rotate about the longitudinal center line of the valve chamber.
  • a drive 66 extends from the right end of shaft 56, as viewed in FIGURE 7, through end plate 44 to permit the shaft to be rotated.
  • a longitudinally extending slot 68 is formed in the side of shaft 56 and carries a plunger or wiper blade 70 which is outwardly biased by a spring 72 into engagement with the internal surface of the valve chamber.
  • the longitudinal chamber of valve body 30 is preferably of generally cylindrical shape.
  • the chamber could have other configurations, so long as that surface portion of the chamber over which wiper blade 70 is oscillated has all points of substantially equal distance from the center of oscillation of the wiper blade.
  • FIGURE 3 shows the valve with the cut-off valve element 54 in its closed position and the plunger in its uppermost position.
  • the shut-off valve 54 is moved to the position shown in FIGURE 4.
  • Shut-off valve member 54 is designed so that when it is in the position shown in FIGURE 4 it just misses the outer surface of shaft 56 by a few thousandths of an inch. This prevents any wear between the two parts while effectively sealing the chamber portion 55 from the remaining portion of the chamber.
  • shaft 56 is rotated clockwise, thus forcing the material in chamber portion 55 through outlet opening 48.
  • shut-off valve 54 When the wiper blade has moved to the position shown in FIGURE 5 it is at the end of its stroke and shut-off valve 54 is then rotated counterclockwise to its closed position as shown in FIGURE 6. Shaft 56 would then be rotated back counterclockwise to the position shown in FIGURE 3, thus causing the wiper blade to draw more batter into chamber portion 55.
  • shut-off valve 54 and the plunger shaft 56 A variety of different mechanisms could obviously be used to rotate shut-off valve 54 and the plunger shaft 56.
  • these drive means comprise gears 74 and 76 carried on the ends of shafts 66 and 62 and rotated through rack gears 80 and 32 driven by double-acting air cylinders 84 and 86.

  • a switch-actuating arm which contacts limit switches at the end of the stroke of the piston rod.
  • Arm 92 mounted on the piston rod of shaft 86 contacts limit switches LS1 and LS3 while arm 94 mounted on the piston rod of cylinder 84 controls limit switches LS2 and LS4.
  • Means are provided to control the upper limit of movement of the piston rod of cylinder 84 so that the movement of wiper or plunger blade 70 can be adjusted to vary the effective volume of chamber portion 55.
  • These means comprise a stop arm 96 carried in a slideaway 97 and moved by an adjustable drive 98.
  • stop arm 96 is provided with an opening through which the piston rod of cylinder 8-4 extends. The lower surface of the stop arm thus provides a stop surface which limits the upward movement of the piston.
  • Arm 96 also carries the limit switch LS2 so that it is always properly positioned with respect to actuator arm 94 no matter what the upper stop position for the piston rod happens to be.
  • C ontrols A variety of different control systems could be used to control the admission of air to the double-acting air cylinders 84 and 86 and thereby control the position of the shut-off valve and plunger. However, according to the preferred embodiment of the present invention, a system as shown in FIGURE 9 is utilized. This system is arranged to perform the following functions:
  • this system is provided with means for manual actuation to make a single deposit or row of deposits, or alternately, to run continuously to dispense rows at any predetermined time interval without regard to the presence or absence of a container.
  • this system includes means 106 and 108 for sensing the approach of a container.
  • This means could be of a variety of types, such as an electric eye, a limit switch, or a proximity switch; however, as shown it comprises a conventional proximity switch, provided with a pair of sensing elements 106 which when approached by a container causes switch 108 to momentarily energize the relay coil CR1 to momentarily close its switch CR11.
  • Sensing elements 106 are mounted beneath the conveyor belt 18 at a location spaced from the depositing valve (see FIGS. 1 and 2). Although a single sensor could obviously be used, it is preferred to use two sensors positioned at locations spaced transversely of the belt. This avoids the necessity of closely regulating the lateral positioning of the containers.
  • proximity switch 108 is connected in series with start switch 104 across power lines 101 and 103 provided with a main switch 100 and fuses 102.
  • Timer TDRl is a conventional adjustable timer such as the Cycle-Flex type HPS 17 manufactured by the Eagle Signal Company.
  • the timer includes a motor TM connected through a clutch (not shown) controlled by clutch coil TDRl-C, to an adjustable rotary cam which controls the position of switches 118 and 119.
  • the clutch coil also controls the position of switches 114 and 115, and when energized causes the clutch to be engaged and switches 114 and 115 to be moved to their upper position as viewed in 7 FIGURE 9.
  • the motor TM After the motor TM has run for the set period of time it drives the adjustable cam through the position where it first moves switch 119 into engagement with its upper contact and then opens switch 118.
  • a relay coil CR2 Connected between the upper contact of switch 119 and line 103 is a relay coil CR2. Energization of this coil causes it to close switches CR21 and CR2-2.
  • a counter C2 Connected between the lower contact of switch 119 and line 103 through the upper contacts of a selector switch 134 is a counter C2.
  • This counter is a conventional counter such as one of the PCC series sold by the Eagle Signal Company. In general, it comprises coil or solenoid operated mechanical ratchet mechanism which registers one count each time the coil is energized and de-energized. With selector switch in the upper position the counter C2 will register one count for each actuation of proximity switch 108. However, with the selector switch in the lower position, the counter will count the total number of cycles of the depositing valve without regard to the number times switch 108 is actuated.
  • a second counter C1 which functions to selectively control the number of deposits made by the dispensing valve after timer TDR1 times out.
  • this is a conventional counter such as type I-IZ172A6 sold by the Eagle Signal Company.
  • the counter comprises a clutch coil 126 which when energized moves switch 110 into contact with its upper contact.
  • the counter includes a count coil which each time it is energized and deenergized actuates a ratchet wheel and cam mechanism (not shown) which controls the positioning of switches 109 and 111.
  • the clutch coil 126 additionally controls a stop pawl in contact with the ratchet wheel. This stop pawl functions to prevent reverse movement of the ratchet wheel until clutch coil 126 is de-energized.
  • a pulse-type limit switch LS1 Connected with the lower contact of switch 111 through a conventional pulse-type limit switch LS1 (such as type 1PD1 sold under the trade name Micro-switch) is a second timer TDR2.
  • This timer is conventional (such as type 5231C001Q-KX sold by Automatic Timing and Controls Inc.) and functions to receive a pulse through limit switch LS1 and, after a regulatable time delay momentarily closes its contact TDRZ-l.
  • the coils 1A, 2A, 1B, and 2B are the coils shown in FIGURE 8 which control the positioning of the air admission valves 88 and 90.
  • the limit switches LS1, LS2, LS3, and LS4 are the limit switches shown in FIGURE 8 that are actuated by the switch actuation arms 92 and 94 carried on the piston rods of air cylinders 84 and 86.
  • FIGURE 9 Also shown in FIGURE 9 is a rectifier 144 and an RC 0 circuit 146.
  • proximity switch 108 momentarily energizes relay coil CR1, thereby momentarily closing switch CR11.
  • Energization of the clutch coil causes the clutch to be engaged and connect timer motor TM with its switch operating cam.
  • Energization of the clutch coil also closes switch 114 and moves switch 115 to its upper contact. This provides a holding circuit for the timer through line 116, switch 114, switch 118, and lines 120 and 122 to line 103.
  • switch 119 is moved to its upper contact completing a circuit from line 101 through line 116, switch 115, switch 119 through relay CR2 to line 103.
  • the switch 113 opens thus deenergizing the timer motor and the timer clutch coil. This permits switch 114 to open and switch to move to its lower contact. However, the momentary energization of relay coil CR2 causes it to momentarily close its switches CR2-1 and CR22. Closing of switch CR2-1 causes counter clutch coil 126 to be energized and switch 110 moved to its upper contact. This completes a holding circuit for the counter through line 107, switch 110, switch 109, line 128 and coil 126 to line 103.
  • valve 90 (see FIGURE 8) to move to the position in which air is admitted to the upper half of cylinder 84 causing the piston to move downwardly and rotate blade 70 clockwise to the position shown in FIGURE 5.
  • switch arm 94 contacts limit switch LS4 and causes it to move to its upper position, as viewed in FIGURE 9.
  • limit switch LS4 was in the lower position as shown in FIG- URE 9
  • the RC circuit 146 was charged through rectifier 144, switch LS4, and line 141.
  • the switch LS4 is in its upper position
  • the RC circuit 146 discharges through line 141 switch LS4 and line through solenoid coil 2B.
  • This causes air valve 88 to be moved to the position in which air is supplied to the upper half of air cylinder 86. This causes the piston to move downwardly and rotate shut-oif valve 54 to the closed position shown in FIGURE 6.
  • Limit switch LS1 is of the type that momentarily closes when it is held in the down position. If counter C1 has been set for one count closing of switch LS1 will have no effect on timer TDRZ because the switch 110 will be in its lower position and the circuit through timer TDRZ not completed. Thus, not-hing more will happen until a second pan is sensed by sensors 106 and proximity switch 108 actuated at which time the above described cycle of operation will again be repeated. However, assuming that counter C1 has been set for two or more counts, i.e.
  • timer TDR2 is adjustable so that the time between its energization and the time it closes its contact TDR2-1 can be varied.
  • switch TDR21 is closed and solenoid coil 1A is again energized through switch TDR2-1, line 101 and 135. This causes the same cycle of operations which previously took place with the closing of CR2-2. This cycle of operations will be repeated until counter C1 counts out.
  • the spacing between the deposits following the first sensing of a pan by sensors 106 can be varied.
  • This aspect of the invention is important since it permits any desired number of deposits to be made at any particular spacing.
  • Means are also provided to permit the system to run continuously without regard to the sensors 106 sensing a pan or material receiving surface. These means comprise a switch 150 in parallel with switch CRl-l. By closing switch 150 timer TDR1 Will be continuously energized to repeatedly actuate the depositing valve in the manner previously described.
  • a normal open switch 152 is provided to permit the timer TDR1 to be momentarily energized to perform a single cycle of operations in the manner described above with regard to closing of switch CRl-l by proximity switch 108.
  • the system in effect, provides a memory for ease in making future setups. After first determining the timer and dispensing quantity settings for the particular combinations of pan size and conveyor speeds which the bakery uses, the settings can :be recorded for future reference. Subsequently, it is only necessary to make the settings as previously determined and the apparatus is ready for operations.
