Bottle Metering and Transport
• a starwheel 105 meters bottles from the bottle infeed conveyor into groups for loading into the carriers.

• the lugs 108 engage the rearmost bottle in each column of a bottle grouping.
• a single lug may be used to engage the rearmost bottle in a column
• paired sets of lugs 108 allow more stable contact with bottles because two points on the bottle are contacted rather than one.

• Each bottle gripper 113 is a block-like member with a series of adjacent C-shaped cavities for receiving bottles 1.
• the number of C-shaped cavities corresponds to the number of bottles to be contained in each column of the carrier 3. For example, a carrier for six bottles would have three bottles per column and a carrier for eight bottles would have four bottles per row.
• the invention employs a single chain 111 to circulate the bottle grippers 113 while maintaining the grippers 113 in a constant orientation facing the center of the apparatus 10. Referring now particularly to Fig.

• the pairs of belts 92, 94 and 93, 95 of the declination belt assembly 90 are spaced apart so that the carriers 3 may pass between them.
• one pair of upper 92 and lower 94 belts is considered the "right" declination belts while the opposing upper 93 and lower 95 belts are considered the "left" pair.
• Each of the four belts 92, 93, 94, 95 is an endless belt. The spacing shown between the facing surfaces of each pair of belts is for illustration purposes.
• each pair of belts 92, 94 and 93, 95 belts are disposed closely enough so that the panels 910, 912 of the carrier 3 are wedged between each pair of moving belts.
• the carriers 3 are thus translated along the apparatus 10 by the moving belts.
• belts assembly 90 Although only the general structure of the belts assembly 90 is shown it can be appreciated that means of endless belt movement commonly used by those skilled in the art are employed. For example, the use of a circular roller mechanism 91 disposed at the ends of the belt runs with additional rollers disposed between the ends of the runs to maintain opposing belts in surface-to-surface contact (as is illustrated in Fig. 9 with reference to the rollers 74 in the nip belt assembly 70).
• the belts' 92, 94 and 93, 96 movements are in synchronization with the movement of the bottle-group conveying mechanism (that is, the bottle- gripper conveyors 112) .
• Each carrier 3 is received by the declination belts such that each carrier 3 overlies a group of bottles 5.
• an optimum angle of declination of the pairs of belts 92, 94 (and 93, 95 which are parallel to 92, 94 but not visible in Fig. 26) and the horizontal plane of the groups of bottles 5 is shown as an angle denoted "A" of 4 degrees.
• the angular orientation of the declination belts 92, 94 and 93, 96 causes the carriers 3 to gradually descend upon the groups of bottles 5. Lowering of the carriers 3 is aided by the overhead declination block assembly 100 in which a series of handle-engaging blocks 102 are mounted upon an endless chain which in turn is in alignment and synchronization with the declination belts.
• each block 102 has a groove or slot 103 for receiving the handle of a carrier 3.
• the overhead assembly is disposed with respect to the declination belts 92, 94 and 93, 96 such that as carriers are moved by the belts 92, 94 and 93, 96 the apex of the carrier 3, that is, the top of the handle portion, is engaged by the groove/slot 103 and helps stabilize and reinforce the movement of the downward traveling carriers.
• the blocks may be spaced for synchronization but a simple means of utilization as illustrated is to have the blocks 102 abut one another so that essentially a continuous groove or slot is formed.
• an alternate version of the declination belt assembly 90 includes a guide 98, 99 positioned to engage the fold line created between each bottom panel 910, 912 and an adjacent side wall of the carrier 3.
• the guide 98, 99 is parallel and coextensive with the length of the belts 92, 94 and 93, 96.
• the guides 98, 99 thus further aid in lowering the carriers 3 and further stabilization of the carriers 3 as they are lowered.
• each carrier is only substantially lowered prior to the departure of the carrier panels 910, 912 from the declination belts 92, 94 and 93, 96 and departure of the handle portion from the overhead declination blocks 102.
• Completed lowering of each carrier 3 over a group of bottles 5 is achieved in the seating wheel assembly 120 which follows the declination belt assembly 90 and overhead declination block 100 assemblies.
• Carriers 3 and groups of bottles 5 exit the declination belt 90 and overhead declination block 100 assemblies as a unit denoted by the number 6 in Fig. 26.
• the carrier-bottle unit 6 is a package in which the fully-erected carrier 3 is substantially but not completed lowered over the bottle grouping 5.
• the carrier 3 is either angularly disposed with respect to the bottle-grouping 5, due to the angular placement of the carrier 3 over the bottles 5, or the carrier 3 may be horizontally disposed as it exits the declination section due to contact of the rearmost end of the carrier handle by the last declination block 102.
• the seating wheel assembly 120 is a ferris-wheel-like structure wherein seating blocks 122 are attached to a revolving wheel or drum 124 in a manner which maintains their downwardly-directed (that is, wherein the handle- receiving slot is downwardly directed) orientation.
• the seating blocks 122 maintain the same orientation as they travel in the circular path of the wheel 124. Suitable means for preservation of the orientation of the seating blocks 122 as the wheel 124 turns is to allow the seating blocks 122 to freely pivot with respect to the wheel. This arrangement is simply illustrated in Fig. 26. A more precise means of maintaining alignment is illustrated in Fig. 30.
• Fig. 30 illustrates the use of a planetary gear system to maintain the downward orientation of the seating blocks.
• the seating blocks 122 are mounted upon "planet" gears 127 that revolve around a centrally disposed "sun” gear 126 in known mechanical manner.
• the seating blocks 122 have a handle-receiving groove or slot 123 like the handle-receiving groove/slot 103 of the overhead declination blocks 102. Since the handle-receiving portion 123 of the seating block 122 is not fully visible in the illustration of Fig. 5 and not visible in Fig. 26, the blocks 102, 122 may be considered identical in this aspect.
• the rotation of the wheel 124 is synchronized with the movement of the carrier-bottle units 6 so that consecutive seating blocks 122 engage the handles of consecutive carriers of the units 5.
• the movements of the wheel 124 and carrier-bottle unit conveyor are synchronized such that the handle of a carrier-bottle unit 6 intersects the angular path of the wheel 124 as the handle-receiving portion 123 of a seating block 122 reaches that same point.
• the seating block 122 engages the handle of a carrier rotation of the wheel moves the block 122 both downward and forward. Placement of the carrier 3 over a group of bottles 5 is thus completed and the carrier is fully "seated" with respect to the group of bottles 5.
• the unit of a group of bottles 5 and a fully-seated carrier 3 is denoted by the reference numeral 7 in Fig. 26.
• the unit 7 is now ready for closure.
• the seating blocks 122 may be spring-loaded such that if a bottle is engaged rather than a carrier handle the resistance will cause the seating block to be pushed backward toward its point of coupling. In this manner damage and jamming is prevented if a misaligned bottle is engaged by a seating block 122.
• the bottles 1 are shown in groupings 5 of two by three arrays, a total of six bottles per group. However, as previously mentioned, it is noted that the system of the invention works well with various multiples of bottles to be packaged.

• Closure of the Carrier Closure of the bottom of the carrier 3 may be achieved by several means. For example, adherence of the bottom panels 910, 912 to one another by an adhesive. Another effective means for closure is the use of a locking mechanism known as a "punch lock" in the packaging field wherein the outermost of the two bottom panels has male locking members that are superimposed over corresponding female apertures and members formed in the inside bottom panel. To help effectively close the bottom of the carrier 3, particularly if the carrier will be closed utilizing a punch lock, the two bottom panels 910, 912 can be drawn inwardly to help align the two bottom panels 910, 912.
• lug sets 182 engage pull holes (also known as alignment apertures or tightening apertures) 914 (which can be seen in Fig. 3) in the bottom panels 910, 912 of the carriers 3.
• Each lug set 182 has an outwardly-biased moveable lug member 184 and a stationary lug member 186.
• Outward biasing may be accomplished by the spring 196 shown or other suitable biasing mechanism.
• a pair of opposing lug sets 182 is mounted upon a pair of support rods 190.
• the pairs of lug sets 182 are mounted upon conveyors such as endless chains 188.
• the moveable lug member 184 of each set is spring- biased outwardly and is moved inwardly along the support rods 190 through moving contact with the cam rail 192.
• the moveable lug members 184 of the lug sets 182 are in a retracted position prior to translating inwardly upon the ramp 194.
• the tightening apertures 914 of the carriers 3 are initially engaged by the lug sets 182 when the moveable lug members 184 are retracted (that is, prior to riding up the ramp 194) .
• Each moveable lug member 184 has an angular- shaped protruding portion 185 that is configured to correspond to and be closely received by the apex of the triangular-shaped tightening apertures 914.
• Each stationary lug member 186 has a lip-like linear protruding portion 187 that is configured to correspond to and be closely received by the base of the triangular-shaped tightening apertures 914.
• the bottom panels 910, 912 of carriers 3 are in face-to-face partially overlapping relationship when the packages 7 leave the folding and gluing area 140 of the apparatus 10. As the moveable lug members 184 travel the leading ramp 194 they pull the bottom panels 910, 912 inwardly to a predetermined position.
• the stationary lug members 186 help prevent the bottom panels 910, 912 from being drawn too far inwardly.
• the leading ramp 194 may be stepped in known manner to provide two tiers of ramps for the moveable lugs 184 so that leading and trailing moveable lug members may move inwardly essentially simultaneously to prevent a "scissoring" effect when the bottom panels 910, 912 are drawn together.
• cam followers of the leading moveable lug members engage only the upper-tiered ramp.
• the upper-tiered ramp is more steeply inclined than the lowered-tiered ramp. The less steep lower-tiered ramp is contacted only by the cam followers of the trailing moveable lug members.
• Figs. 37 and 38 as the bottom panels 910, 912 of the carrier 3 are drawn together the tops of bottles are engaged by belts 402 of a bottle stabilizer assembly 400.
• the belts 402 rotate in the same direction as the direction of carrier travel and at the same speed.
• the bottle stabilizer 400 prevents bottles from rising upwardly out of the carrier as the bottom panels 910, 912 are drawn together as described above.
