Abstract
ABSTRACT
Discloses a machine for feeding groups of bottles in case formation in one by one fashion onto an outlet conveyor. The machine involves the use of a spacing conveyor interposed between the feed conveyor and the outlet conveyor and channel means disposed over the end of the feed conveyor so as to orient the groups of bottles in side-by-side rows as they were taken from the case. Spacing guides are positioned on the spacing conveyor at an angle so that the row of bottles side-by-side relation are retained on the spacing conveyor while the foremost row is angled so that the bottles reach the outlet conveyor at different times and can the be carried away one at a time. The spacing guides are angled so that the last bottle in one row is fed onto the outlet conveyor before the first bottle of the next row is fed onto the outlet conveyor. A series of gates are supplied at the end of all but the last channel so that the gates separate the bottles as they are fed onto the outlet conveyor. A timing screw driven in the same direction as the outlet conveyor and in synchronism therewith engages each of the bottles in a pocket as it is fed onto the outlet conveyor and carries it along the outlet conveyor.

Description
~05i~9 This invention relates to a bottle orientation mechanism and more particularly to a machine for receiving a variety of bott:Les in case formation from a carton unloader and for arranging said bottles in side-by-side rows so as to feed them in tLmed manner onto a conveyor or the like.
Empty bottles are dumped from cases onto a conveyor prior to their being filled. These bottles are thus lined up on the conveyor belt in the same pattern that they were in the carton.
The problem is to get the bottles into a single line to be fed to the filling equipment. The best solution is to release the bottles onto an outlet conveyor one at a time to avoid two bottle~ reaching the same point at the same time and jamming.
In instances invslving pint and half-pint bottles, for example, there is an additional problem of turning the bottles in a direction approaching 90 degrees to be fed onto the outlet con-veyox.
According to the present invention, the bottles, after being unloaded from the carton onto the feed conveyor are fed into channel guides so as to be oriented in side-by-side rows.
2Q Further, there is provided a spacing conveyor interposed between the feed conveyor and the outlet conveyor, normal to the feed conveyor so that the feed conveyor feeds onto the spacing conveyor. The direction of the conveying surface of the spacing conveyor is opposite to the direction of travel of the conveying surface of the outlet conveyor directly adjacent to it. Further, spacing guide means are positioned on the spacing conveyor at an angle so that the separating or leading point of the spacing guide can split a row of bottles apart and push the row o bottles out toward the outlet conveyor at an -1- ~
1~)5i~g angle generated by the spacin~ guide. Simultaneously, the retaining side of the spacing guide acts to retain the subse-quent row of bottles and angles these rows out sufficiently to provide space for the separating point of the subsequent spacing guide to plow in between it and a subsequent row of bott:les. The spacing guide is fabricated of indi~idual blocks of high-density polyethylene or other polymeric material so that contact with the glass bottles does not cause undesirable sound or breakage. Further, there is provided at the end of each of the channel guides, gates, hinged and fabricated of high density polyethylene so as to physically separate each of the bottles leaving the channel as it goes onto the outlet conveyor. Thus as the bottle leaves its channel, it opens up the gate and the subsequent bottle moving along the outlet conveyor closes the gate for the next row of bottles to be fed onto the spacing conveyor. Thus, the bottles as they are fed onto the conveyor are physically separated from each other and do not cause any undue noise or breakage. Further, there is provide~ a timing screw having heIical flights forming pockets 23 between the two points of the heIical 1ight to engage a bottle leaving its channel and propel it along the outlet conveyor.
The timing screw, according to this invention, is fabricated of a polymeric material, again such as high density polyethylene so as to eliminate noise and breakage to allow speeds of convey-ing bot~les along the outlet conveyor of up to and in excess of 400 bot~les per minute.
Referring now to the drawings, Fig. 1 is a perspective view of the present invention illustrating the relationship of the feed conYe~or to the spacing conveyor and the rela~ionship .: .. . .
:~ ' ' ' '. ' 10~ 9 of the feed conveyor and spacing conveyor to the outlet con-ve~or and the relationship of the outlet conveyor to the timing screw.
Figs. 2, 3, and 4 are diagramatic illustrations of the machine of this invention in operation, illustrating the relation-ship of guide means in retaining, guiding, and moving bottles from the feed conveyor to the outlet conveyor and which further illustrates the relationship of the spacing and outlet conve~or to the timing screw.
Referring now to the drawings in detail, the feed conveyor 1 comprises an endless belt of flat articulated chain links as is indicated in Fig. 1 and moves in the direction illustrated the arrow.
The spacing conveyor 2, made of flat articulated chain links is located with its long axis normal to the long axis of the feed conveyor 1 so that the feed conve~or feeds bottles onto the spacing conveyor. The conveying surface of the spacing conveyor moves in the direction illustrated which, it will be noted, is opposite to the direction of the conveying surface of outlet conveyor 3. Again, the outlet conveyor 3 i~ comprised of flat articulated chain links. Channel support means 8 are supported by means of transverse bars 6 trained through holes 7 in post 5 near the outlet portion of the conveyor. For purposes o description, the proximal channel guide 13 extends all the way across the spacing conveyor 2 to the inner edge of the outlet ~onveyor 3. These channel guides then form proximal channel 15, middle channel 16 and distal channel 17. Gate 45 is connected to middle channeI guide 10 by means of hinge 48 held into position by pop rivets 49, while gate 46 is connected to lOS14~9 channel guide 12 again by means of a hinge 40 so as to be swinging-ly disposed at the end of the proximal channel 15 and the middle channel 16.
. In the modification of the invention illustra-ted, the motor generally is indicated at 19 and is utilized as a drive means for both the spacing conveyor 2 and the outlet conveyor 3 as well as the timing screw 37. It is, of course, within the scope of this invention to run each of the conveyors by a separate driving means. Nevertheless in the modification il~ustrated in Fig.
1, the motor 19 is connected to shaft 20 which in turn is connected to belt 21 which is trained over drive sheave 23, tension sheave 24, and a driven sheave (not shown). The driving chain is trained over the tension sprocket 29 and trained under the drive sprocket 27 which drives the outlet conveyor 3 thence over drive sprocket 28 (for spacing conveyor 2) and thence over the driven sprocket (not shown) for the spacing conveyor 2. The tension sprocket 29 drives the shaft 30 to drive sprocket 31 which by means of chain 33 train-ed thereover drive sprocket 32. Shaft 34, for sprocket 33, is connected to a gear reduction box 35 which in turn drives the shaft 36 of the timing screw 37 in syncronism with the spacing conveyor

Shaft 34, for sprocket 33, is connected to a gear reduction box 35 which in turn drives the shaft 36 of the timing screw 37 in syncronism with the spacing conveyor
2 and the outlet conveyor 3. The timing screw 37 is fabricated of high density polyethylene and consists of a series of helical flights 38 forming pockets 39 which engage with the bottles leaving a particular channel and transports same down the outlet conveyor 3.
The guide means 50 are made up of a series of blocks 52 of high density polyethylene and form at the front a sepa-rating or plowing point 51, a retaining edge 53 and a guiding edge 54. At the end of the guiding edge 54 is a backup edge 55 which runs " - ' ' ' ' ' :

OPE~TION
The operation of the conveyor and the guiding means can best be illustrated by refere~ce to Figs. 2, 3, and 4 wherein the bottles are shown numbered 1 through 15, being fed from the feed convevor 1 onto the spacing conveyor 2 and then outward to the outlet conveyor 3.

OPE~TION
The operation of the conveyor and the guiding means can best be illustrated by refere~ce to Figs. 2, 3, and 4 wherein the bottles are shown numbered 1 through 15, being fed from the feed convevor 1 onto the spacing conveyor 2 and then outward to the outlet conveyor 3. It will be ntoed that in Fig. 2, bottles 1, 2, and 3 have already moved onto the outlet conveyor
3 and are moving in the direction shown by the arrow to the filling equipment. Each of the bottles is shown engaged in a pocket 39 of the timing screw 37. The square edges of the individual pol~meric blocks 52, forming backup edge 55 of guide means 50 is shown in engagement with the back of the bottles as they feed into pockets 39 of the timing screw 37. Further, it will be noted in Fig. 2 that bottle 2 has closed gate 45 while gate 46 is open awaiting contact with bottle 3 which will in turn close it. Bottles 4, 5, and 6 have now assumed the angle generated by the retaining edge 53 of the guiding means so as to be in position for the plowing point 51 of guiding means 50 to separate the rows 4l 5, and 6 from rows 7, 8, and 9. Once this is accomplished, as is -shown in Fig. 3, the row of bottles formed b~ 4, 5/ and 6 are pushed by the guiding edge 54 of the guiding means 50 outwardly and transversely to the outlet con-veyor 3 so as to feed off in one-by-one fashion. Again, it will be shown that bottle 4 being sent off of the spacing conveyor 2 onto outle~ conveyor 3 is opening gate 45 while gate 46 is still in close~ position.
lQSl~9 Referring now to Fig. 4, bottles 7, 8, and 9 retained in angular position by the retaining edge 53 of the guiding means 50 and subsequent rows illustrated by 10, 11, 12, begin to take on the angular configuration o the bottles in the preceding rows 7, 8, and 9. As is shown, the square edge of the individ-ual polymeric blocks 52 forming the backup edge 55, backs up the bottle 4 and holds it in proper engagement for fittin~ into pockets 39 of the conveying screw 37, so that it can be propelled rapidly along outlet conveyor 3.
As will be obvious, if this apparatus is utilized in con-junction with pint bottles, the pint bottles will fulcrum around the end 11 of the channel members 9, 10, 12, or 13 and again be fed into the pocket 39 of the timing screw properly for transportation down the outlet conveyor 3. While the material of fabrication of the timing screw, the polymeric blocks 52 and the gate~ 53 have been indicated as high density polyethylene, it is quite obvious that other materials can be used which have a certain amount of resiliency so as to eliminate noise and minimize breakage of the glass bottles. Thus, for example, even wood could be utilized, however, high density polyethylene, nylon, Teflont or other relatively high-quality : i.
pol~meric materials can be used all as within the skill of those ski~led in the art.
