DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(11) A fitment delivery system for reducing down time of pouch manufacturing and improving the quality of sealing the fitment to the pouch is provided. The fitment delivery system includes a fitment deliverer configured to accumulate a plurality of fitments and deliver an individual fitment to a respective carrier. Thus, by accumulating the fitments the fitment delivery system prevents down time caused when a fitment is not properly position to be received by a robotic arm.

(12) The fitment delivery system further includes a fitment heater. The fitment heater is downstream of the fitment deliverer. The fitment heater is configured to heat the fitments prior to being inserted into the pouch. Accordingly, the fitments are at an optimal temperature for pouch sealing operations and thus the system reduces cracks in the fitment which may occur when a fitment is too cold for sealing operations.

(13) The fitment delivery system further includes a fitment inserter. The fitment inserter is configured to both pick up and insert the fitment into the pouch at the same time. The fitment inserter includes an arm support and a pair of fitment grippers disposed on each end of the arm support. The arm support is rotatable mounted to a piston. The piston is configured to drive the arm support between an up position and a down position. Accordingly, the fitment delivery system increases the efficiency of pouch formation by having a single device configured to both pick up and insert a fitment into the pouch.

(14) With reference now to FIG. 1, a fitment delivery system 10 for reducing down time of pouch 14 manufacturing and improving the quality of sealing the fitment 12 to the pouch 14 is provided. The term fitment 12 as used herein may reference the spout individually or the spout with the cap. The spout provides access to the contents of the pouch 14. In some cases, the pouch 14 may be fitted with a cap to close the spout. The fitment delivery system 10 may be used with a bowl feeder 16 and a pouch forming system 18.

(15) The bowl feeder 16 includes a bowl 20 configured to receive a plurality of fitments 12. The bowl 20 vibrates and rotates the fitments 12 and feed the fitments 12 to an output channel 22, wherein the fitments 12 are positioned to be inserted into a pouch 14. For illustrative purposes, the bowl feeder 16 is shown as having two output channels 22, however it should be appreciated that that the bowl feeder 16 may have only one output channel 22 or more than two output channels 22, and the number of output channels 22 shown are provided for illustrative purposes only and is not intended to limit the scope of the appended claims.

(16) The pouch forming system 18 includes a plurality of stations configured to form a pouch 14. The pouch forming system 18 includes a pouch opening station 24 where the pouch 14 is opened, a fitment sealing station 26 where the fitment 12 is sealed to the pouch 14, and a pouch filling station 28 wherein the pouch 14 is filled. It should be appreciated that the pouch 14 may be filled through the fitment 12 or may be filled through the pouch opening before the fitment 12 is sealed thereto.

(17) With reference to FIG. 1 and also to FIG. 2, the system includes a conveyor 30 driven along a closed loop, a fitment deliverer 32, a fitment heater 34, and a fitment inserter 36. The fitment deliverer 32 positioned with respect to the conveyor 30 so as to individually drop the fitments 12 into one of the plurality of carriers 38. The fitment deliverer 32 includes a chute 40 configured to accumulate a predetermined number of fitments 12 in a line. The fitment deliverer 32 is positioned with respect to the conveyor 30 so as to individually drop the fitments 12 into one of the plurality of carriers 38. The fitment heater 34 is disposed downstream from the fitment deliverer 32. The fitment heater 34 is configured to emit heat. The fitment heater 34 is positioned with respect to the conveyor 30 so as to heat the fitments 12 to a predetermined temperature. The fitment inserter 36 is disposed downstream from the fitment heater 34. The fitment inserter 36 includes an arm support 42 and a pair of fitment grippers 44 (See FIGS. 6A-6D). The fitment inserter 36 is positioned with respect to the conveyor 30 so as to pick up a fitment 12 off each one of the plurality of carriers 38 and insert the fitment 12 into the open pouch 14.

(18) The conveyor 30 is configured to move the carriers 38 in a loop. However, it should be appreciated that any conveyor configured to carry an item in a loop currently known and used in the art may be adapted for use herein. For illustrative purposes, the conveyor 30 is shown as a chain 46 having three chain drives 48. Any chain drive 48 currently known and used in the art may be adapted for use herein. The loop is shown as having a generally triangular dimension having a first side leg 50, a second side leg 52 and a base leg 54. One of the chain drives 48 is mounted to one end of the loop where the first and second side legs 50, 52 connect and the other chain drives 48 are spaced apart from each other and are generally coaxial to each other so as to form the base leg 54 of the loop.

(19) The fitment deliverer 32 is disposed on the first side leg 50. The fitment heater 34 is disposed on the second side leg 52. The fitment inserter 36 is disposed on the base leg 54. The conveyor 30 is configured to move the carrier 38 from the fitment deliverer 32 to the fitment heater 34, from the fitment heater 34 to the fitment inserter 36 and from the fitment inserter 36 back to the fitment deliverer 32. At the fitment deliverer 32 the carriers 38 are empty and a fitment 12 is dropped into the carrier 38. The carrier 38 is then moved to the fitment heater 34 where the fitment 12 is heated to a predetermined temperature. The warmed fitment 12 is then moved to the fitment inserter 36 where the heated fitment 12 is picked off the carrier 38 and sealed to the pouch 14. The conveyor 30 is configured to rotate in a clockwise direction so as to move the carrier 38 to the fitment deliverer 32, fitment heater 34, fitment inserter 36 and back to the fitment deliverer 32 in the sequence described above.

(20) The carriers 38 are fixedly mounted to the chain 46. The carriers 38 are generally equidistant away from each other. The carriers 38 are configured to receive a fitment 12 from the fitment deliverer 32. Specifically, the carriers 38 are configured to catch the fitment 12 as the fitment 12 is dropped form the fitment deliverer 32. The carrier 38 includes a base 56 mounted to the conveyor 30. The base 56 is a generally rectangular block formed of a durable and rigid material such as steel. The base 56 has a top surface 58 configured to accommodate the dimensions of the fitment 12. The carrier 38 includes four prongs 60 which project upwardly from the top surface 58 and are shown generally disposed on each corner of the top surface 58. The prongs 60 are generally elongated members and the ends of each prong may be bent outwardly with respect to the center of the top surface of the base so as to provide additional tolerance for catching the fitment 12. It should be appreciated that the prongs 60 have a sufficient length to help guide the fitment 12 as it falls onto the base and the prongs 60 further assist in keeping the fitment 12 in a generally upright position.

(21) The conveyor 30 may be controlled by a programmable logic controller 62 configured to drive the chain 46 along the loop. Preferably, the chain 46 is indexed so as to move a predetermined distance which allows the carriers 38 to stop at the fitment delivery system 10 and the fitment inserter 36. Further, indexing the movement of the chain 46 allows the carriers 38 and the fitments 12 held therein to be exposed to the heat emitted from the fitment heater 34.

(22) With reference again to FIG. 1, the fitment delivery system 10 is disposed along the first side leg 50 of the loop. The chain 46 is driven in a counter clockwise direction as indicated by the arrow, and the fitment heater 34 is disposed downstream the fitment delivery system 10. Thus, fitments 12 are dropped in a carrier 38 at the fitment deliverer 32 and are carried to the fitment heater 34. The fitments 12 are heated and then carried to the fitment inserter 36 which is downstream the fitment heater 34. The fitment inserter 36 picks a fitment 12 off of the carrier 38 and inserts the fitment 12 into the pouch 14. Thus, carriers 38 arriving at the fitment delivery system 10 are empty and ready to receive another fitment 12.

(23) It should be appreciated that the operation of the conveyor 30, the fitment heater 34, the fitment inserter 36 and the fitment delivery system 10 may all be controlled by the programmable logic controller 62. Thus, the movement of the chain 46, and the actions of the fitment deliverer 32, fitment heater 34 and fitment inserter 36 are synchronized so as to allow for the smooth and undisrupted manufacturing of the pouch 14.

(24) With reference now to FIGS. 3 and 4, a fitment deliverer 32 is provided. The fitment deliverer 32 is configured to accumulate a predetermined number of fitments 12 in a line and individually drop the fitments 12 into an empty carrier 38. The fitment deliverer 32 includes a chute 40. For illustrative purposes, the chute 40 is shown as having two lanes 64. Each lane 64 is coupled to a respective output channel of the bowl feeder 16. The chute 40 is configured to hold a plurality of fitments 12 in a line so as to allow the fitments 12 delivered by the bowl feeder 16 to accumulate therein. However, it should be appreciated that the fitment deliverer 32 is configured to receive fitments 12 from the bowl feeder 16, and thus the fitment deliverer 32 would have a number of chutes 40 corresponding to the number of channels 22 the bowl feeder 16 has. Thus, in instances where the bowl feeder 16 has only one channel 22, the fitment deliverer 32 would have only one chute 40.

(25) Each lane 64 includes an elongated portion 66 configured to allow a predetermined number of fitments 12 to be stored therein. The elongated portion 66 includes a proximal end configured to receive fitments 12 from a corresponding output channel 22. The chute 40 further includes an arcuate end portion 68 disposed on the distal end of the elongated portion 66 so as to allow the fitment 12 to drop into the carrier 38. The bowl feeder 16 feeds fitments 12 into the elongated portion 66. The elongated portion 66 is angled so as to allow gravity to assist in feeding the fitments 12 towards the arcuate end portion 68.

(26) With reference now to FIG. 4, an isolated view of the elongated portion 66 of the chute 40 is provided. FIG. 4 shows two elongated portions 66, each are similar to the other and thus an explanation of one is sufficient to describe the other. The elongated portion 66 is configured to guide the fitment 12 towards the arcuate end portion 68. The elongated portion 66 includes a track 70 which helps guide the fitment 12 and maintain the fitment 12 in a predetermined position so as to be ready for pouch 14 assembly steps. In the instant case, it is preferable to have the fitments 12 standing upright so that the fitment inserter 36 may place the base of the fitment 12 into the opening of the pouch 14. Accordingly, the track 70 is configured to feed the fitment 12 into the arcuate end portion 68 with the base positioned downstream of the spout.

(27) The fitment deliverer 32 includes a fitment feeder 72 configured to move the fitments 12 down the track 70. In an illustrative embodiment, the fitment feeder 72 is a pair of belts 74 formed in a loop and extending the length of the track 70. The track 70 includes a pair of spaced apart bars 76 disposed above the pair of belts 74. As shown, the sides of the fitment 12 are held between a respective bar and belt 74. The belt 74 is rotated by a belt drive 78 thus moving the fitment 12 towards the distal end of the elongated portion 66 as shown in FIG. 4. The elongated portions 66 are mounted to a pair of elongated portion stands 80, one of the elongated portion stand 80 is taller than the other. Specifically, the elongated portion stand 80 supporting the proximal end of the elongated portion 66 is taller than the elongated portion stand 80 supporting the distal end of the elongated portion 66.

(28) The belt drive 78 may be controlled by the programmable logic controller 62 or may be continuously running. The belt 74 provides a friction engagement with the fitment 12 driving the fitment 12 towards the distal end of a respective track 70. The fitments 12 are thus continuously building up along the track 70 as the bowl feeder 16 feeds the fitments 12 to the chute 40. The bars are spaced apart from the belt 74 so as to allow the fitments 12 to remain in contact with the belt 74 but without pinching the belt 74 or otherwise loading the belt 74 in such a manner as to place an undue load on the belt drive 78.

(29) With reference again to FIG. 3 and now to FIG. 5, a perspective and an isolated view of an illustrative example of the arcuate end portion 68 is provided. The arcuate end portion 68 is configured to slidingly support the fitment 12 so as to maintain the position of the fitment 12 as it is dropped into the carrier 38. In a preferred embodiment the arcuate end portion 68 includes a pair of spaced apart guides 82 configured to slidingly support the sides of the fitment 12. The guides 82 have a generally U-shaped cross section having a back wall 82a spaced apart from a front wall 82b. A side wall 82c is disposed between the back wall 82a and the front wall 82b so as to define an opening 82d. The opening 82d of the guides face each other. The guides 82 are arcuate so as to transition the fitment 12 from a generally horizontal position to an upright position.

(30) With reference again to FIG. 5, the fitment deliverer 32 further includes a dispensing mechanism 84. The dispensing mechanism 84 is configured to maintain the accumulation of fitments 12 within a respective track 70 and individually release a fitment 12 down the arcuate end portion 68 for gravity fed delivery into the carrier 38. The dispensing mechanism 84 is illustratively shown as having a guide arm 86 rotatable about a guide arm support 88. A guide arm drive 90, drives the guide arm 86 forward, rotating the guide arm 86 about the guide arm support 88.

(31) The distal end of the guide arm 86 includes a keeper 92. The keeper 92 is configured to retain a fitment 12 and release the fitment 12 down the arcuate end portion 68 and into the empty carrier 38. The keeper 92 includes a back stop 94 and a fitment support 96. The back stop 94 is generally orthogonal to the fitment support 96. The fitment support 96 is configured to support the fitment 12 in a generally horizontal platform. The back stop 94 is configured to prevent the fitment 12 from slipping out of the keeper 92 when advanced by the belt 74.

(32) A gate 98 is disposed adjacent the proximal end of the arcuate end portion 68. The gate 98 is configured to open so as to allow one fitment 12 to advance into the keeper 92. Thus, as the belt 74 is rotated the fitment 12 is urged downstream the track 70 of the elongated portion 66 into the arcuate end portion 68. The gate 98 is opened long enough to allow the fitment 12 to pass into the keeper 92 and then is closed.

(33) The guide arm drive 90 drives the guide arm 86 forward, rotating the guide arm 86 about the guide arm support 88 wherein the keeper 92 is moved along the arcuate end portion 68 carrying with it the fitment 12. When the guide arm 86 is adjacent the proximal end of the arcuate end portion 68, the keeper 92 is retreated removing the back stop 94 from underneath the fitment 12 when the fitment 12 is in a generally upright position. As the back stop 94 is removed, the fitment 12 is held within the chute 40 by a back wall 82a of the guides. Accordingly, the fitment 12 is able to free fall out of the distal end of the arcuate end portion 68 into the carrier 38.

(34) With reference again to FIG. 1, the conveyor 30 moves the carrier 38 with the fitment 12 downstream the loop to the fitment heater 34. The fitment heater 34 is disposed along the second side leg 52 of the loop. The conveyor 30 carries carriers 38 holding a fitment 12 past the fitment heater 34. The fitment heater 34 is a heating unit having a heat emitting surface 100 disposed a predetermined distance from the path of the conveyor 30. In a preferred embodiment the heater unit is configured to heat the fitment 12 to temperature between 120-150 degrees Fahrenheit. It should be appreciated that the desired temperature may vary based upon the material the fitment 12 is made of and the sealing conditions used when sealing the fitment 12 to the pouch 14. It should also be appreciated that the time that the carrier 38 is exposed to the fitment heater 34 will also affect how the fitment 12 will achieve the desired temperature.

(35) The conveyor 30 then moves the carrier 38 past the fitment heater 34 to the fitment inserter 36. The fitment inserter 36 is disposed between the conveyor 30 and a pouch forming system 18. The pouch forming system 18 includes pouch grippers 102 configured to hold the pouch 14. The pouch forming system 18 further includes a pouch opening station 24 and a fitment sealing station 26. The pouch 14 is opened so as to receive a fitment 12 and is then transferred to the fitment sealing station 26 wherein the fitment inserter 36 picks a fitment 12 from the carrier 38 and places the fitment 12 into the pouch 14 opening wherein the fitment sealing station 26 seals the fitment 12 thereto.

(36) With reference now to FIGS. 6A through 6D a perspective view of the fitment inserter 36 is provided. The fitment inserter 36 includes an arm support 42 rotatably mounted to a piston 104. For illustrative purposes, the arm support is shown as having two elongated members 42a, 42b. Each elongated member 42a includes a fitment gripper 44. However, the depiction is configured for use with a pouch forming machine 18 which provides two open pouches configured to receive a fitment. Accordingly, it should be appreciated by those skilled in the art that the arm support 42 may have only one elongated member or more elongated members based upon the number of pouches the pouch forming machine is capable of sealing a fitment to. However, in any embodiment the fitment inserter 36 operates in the same general manner as described below.

(37) An arm support drive 106 rotates the arm support 42 one hundred and eighty (180) degrees so as to move the ends of the arm support 42 between the carrier 38 and the fitment sealing station 26. The piston 104 is configured to drive the arm support 42 between an up and down position. In the down position one of the pair of fitment grippers 44 is configured to pick up a fitment 12 off the carrier 38 and the other of the pair of grippers 44 is configured to insert a fitment 12 into the open pouch 14.

(38) The fitment grippers 44 are configured to pick up a fitment 12 from the carrier 38 and also insert a fitment 12 into an opening of the pouch 14. The fitment grippers 44 include an elongated body 108 having an end portion 110 configured to engage the fitment 12. For illustrative purposes only, the fitment grippers 44 include a suction tube 112 configured to pick up the fitment 12 by vacuum pressure. The elongated body 108 includes a central passage in fluid communication with the suction tube 112 for which air may be drawn. However, it should be appreciated that other means of picking up the fitment 12 currently known and used may be adapted for use herein, illustratively including a pair of closable and openable fingers. In another alternative embodiment, the end portion 110 of the fitment gripper 44 includes having a slit configured to engage a fin of a fitment.

(39) With reference now to FIGS. 6A-6D the operation of the fitment inserter 36 is provided. The piston 104 moves the arm support 42 between an up and down position. In the down position, each of the fitment grippers 44 holds a fitment 12. One of the fitment grippers 44 grabs a fitment 12 from the carrier 38 and the other of the fitment grippers 44 places a fitment 12 within an opening of the pouch 14. The fitment inserter 36 leaves the arm support 42 in the down position long enough to allow the fitment sealing station 26 to seal the fitment 12 to the pouch 14. The fitment inserter 36 moves the arm support 42 to the up position wherein the fitment 12 sealed to the pouch 14 remains held by the pouch gripper 102 and is released by the corresponding fitment gripper 44. Simultaneously, the fitment 12 in the carrier 38 is picked up by the corresponding fitment gripper 44.

(40) The arm support 42 is then rotated 180 degrees thus the empty gripper is positioned above the conveyor 30, simultaneously, the conveyor 30 is indexed so as to move a carrier 38 with a fitment 12 generally underneath the empty fitment gripper 44. The fitment gripper 44 hold a fitment 12 is positioned above the pouch 14 forming station. As the arm support 42 is turned, the pouch forming system 18 moves an open pouch 14 to the fitment sealing station 26. It should be appreciated that movement of the conveyor 30, pouch 14 system, and fitment inserter 36 are synchronized such that an empty fitment gripper 44 is positioned above a carrier 38 holding a fitment 12 and the fitment gripper 44 holding a fitment 12 is position above an open pouch 14.

(41) The arm support 42 is then moved to the down position wherein the empty fitment gripper 44 engages a fitment 12 from the carrier 38 and the fitment gripper 44 carrying a fitment 12 places the fitment 12 into the opening of the pouch 14. The fitment 12 is then sealed to the pouch 14 and the cycle continues as described above.

(42) FIG. 6A shows the arm support 42 in the up position, wherein a pair of the fitment grippers 44 are empty and disposed above carriers 38 holding fitments. Another pair of fitment grippers 44 are opposite the other pair and disposed above a pair of open pouches 14. With reference now to FIG. 6B, the arm support 42 is driven to the down position. The fitment grippers 44 above the carrier 38 have engaged a pair of fitments 12. The fitments 12 may be held to a respective fitment gripper 44 by a vacuum pressure provided by the suction tube 112. The other pair of fitment grippers 44 have disposed their respective fitments 44 into an open pouch 14. FIG. 6C shows the arm support moved to the up position. The fitment grippers 44 have picked up a respective fitment 12 off of the carrier 38. The pouch forming station 18 has sealed the fitments 12 to the pouch 14. It should be appreciated that seal bars (not shown) have come in to seal the fitments 12 to the pouch 14. The fitments 12 are held within the pouch 12 as the fitment grippers 44 are moved up by the arm support 42. With reference now to FIG. 6D, the conveyor 30 has been indexed forward so as to bring a pair of carriers 38 holding fitments 12 to the fitment inserter 36. Simultaneously, the pouch forming machine 18 has advanced a pair of open pouches to the fitment sealing station 26. The arm support 42 is rotated 180 degrees as indicated by the arrow and the empty fitment grippers 44 are positioned above the carriers 38 and ready to pick up their respective fitment 12. Simultaneously, the fitment grippers 38 holding fitments 12 are ready to place their respective fitment 12 into a corresponding open pouch 14.

(43) Accordingly, the fitment delivery system 10 is configured to reduce down time for manufacturing pouches 14 with fitments 12 by providing a chute 40 for which fitments 12 may accumulate, improves the process of sealing the fitment 12 to the pouch 14 by preheating the fitment 12 before the sealing process, and increases the efficiency of pouch 14 formation by having a single device configured to both pick up and insert a fitment 12 into the pouch 14.
