Abstract
Description
- This invention relates generally to packers for loading plastic and/or glass bottles into upwardly open cases or trays which are adapted to receive two or more side-by-side columns of bottles in aligned rows. Line pressure from a conveyor moves the bottles across a ramp. Support for the bottles at the load station may be provided by neck ring guides, or by virtue of the fact that the bottles are prepackaged in cartons or six packs or by other suitable means. The trays or cases move upwardly from below the path of the article columns into the load station where each tray is elevated slightly at its rear or aft end by a flight bar conveyor system that is used to synchronize the trays with an overrunning series of parallel collating wheels that are provided with protuberances for downward movement between adjacent columns of articles to form individual groups of articles for deposit in each of the generally rectangular cases or trays.
- Continuous motion packers of the type adapted to handle relatively large plastic soda bottles in two columns are currently available. See for example the apparatus disclosed in U. S. Patent No. 4,90̸1,50̸1 and assigned to the assignee herein. The usefulness of such an apparatus for packing plastic bottles in two or more columns or lanes poses problems for such a packer, and typically, trays for transporting smaller bottles do not have pockets uniformly spaced with respect to one another as do the trays for handling large plastic bottles.
- Patent No. 5,020,306 entitled CONTINUOUS MOTION PACKER FOR FEEDING CONTAINERS IN END-TO-END PACKING CASES and also assigned to the assignee herein teaches that an apparatus can be provided for handling two side-by-side columns of containers or bottles even where the pockets in which the bottles are to be deposited are not equally spaced in the longitudinal direction. However, as in the apparatus of Patent No. 4,901,501 only two side-by-side columns or lanes of plastic soda bottles can be accommodated. US-A-2 699 278 discloses an apparatus according to the preamble of claim 1.
- The general purpose of the present invention is to provide a packer capable of handling two or more columns of bottles and depositing such articles into upwardly open plastic cases or trays such that orderly slugs or charges of articles are deposited in each tray as the trays move end-to-end through the load station.
- The invention provides apparatus for loading columns of articles into upwardly open rectangular cases wherein the cases have end walls and wherein the articles in the columns are arranged adjacent one another, said apparatus comprising: case conveying means for feeding cases end-to-end to and through a load station; and article moving means for advancing the articles in N columns and including a ramp across which the articles move in side-by-side rows by line pressure, said load station being provided at a downstream end of said ramp; CHARACTERIZED IN THAT the case conveying means is suitable for continuously feeding the cases; and a plurality (N plus one) of article separator discs is arranged for rotation one between each adjacent pair of article columns and one adjacent each peripheral column, each disc having first circumaxially spaced article engaging lugs for acting on predetermined article rows in timed relation with the arrival of cases at the load station to retard certain of said rows and create gaps between successive groups of articles, the gaps coinciding with the adjacent front and rear end walls of adjacent cases at the load station.
- Preferably the article separator discs have second, smaller article engaging lugs for moving between rows of articles in each group of articles to guide each row of articles into the cases. Neck ring guides may be provided for supporting articles with necks during their movement through the load station and preferably for suspending the articles vertically at the load station.
- A preferred embodiment of the invention further comprises case indexing means at said load station, said case indexing means comprising flight bars spaced apart by a distance slightly less than the length of the case to be loaded, and each such flight bar being movable upwardly at said load station through a horizontal plane defined by said case conveying means to tilt each case forwardly as it traverses the load station.
- The apparatus of the present invention can pack two or more columns of articles into cases, either individually or in prepackaged subgroups such as six packs of soda bottles. The articles are generally moved down the ramp to the loading station by line pressure and by gravity.

- Fig. 8A is a schematic view similar to that of Fig. 8, but illustrating only the rotating discs with the lugs provided thereon for purposes of separating adjacent rows of articles.
- Turning now to the drawings in greater detail, Fig. 1 illustrates an apparatus according to the present invention as including a fixed frame having legs 10̸ and 12 for supporting the frame. The frame includes a superstructure indicated generally at 14 supporting a conveyor for moving articles in a plurality of side-by-side columns in the general direction of the
arrow 16. Thisarticle conveyor 18 is driven from the head shaft indicated generally at 20̸ by adrive motor 15 best shown in Fig. 2. - Plastic trays or cases to be loaded are fed below the path of the articles on a
case conveyor 22 which provides cases C, C in end-to-end relationship to a pair of spacedapart case conveyors - The
head shaft 26 for thecase conveyor 22 and thehead shaft 25 for the spaced apartcase conveyors beam 28 which is fixed for a particular setup, that is for loading articles of a particular geometry in a particular size case. However, thebeam 28 is vertically adjustable, as for example by the crank 30̸ through a system of four verticallyoriented shafts 32 provided in the legs 10̸ and 12. More particularly, thebeam 28 can be lowered from the position shown in full lines to that illustrated generally in broken lines at 28 in Fig. 1. This adjustability permits handling cases of different height as well as handling articles of different height. Adrive motor 21 operates bothconveyor 22 andconveyors - The side-by-side lanes or columns of articles are moved by line pressure, from the
article conveyor 18, onto an inclined deadplate or ramp indicated generally at 34 in Figs. 1 and 2.Side guides inclined ramp 34, andlane dividers ramp 34 toward a load station indicated generally at 40̸ in Figs. 1 and 2. - The
ramp 34 has adownstream edge 34a which is provided just short of the load station 40̸ so that the articles must be further guided into the load station. Inclined neck ring guides indicated generally at 42 in Figs. 1 and 2 are shown as a preferred means for guiding the columns of plastic bottles into the load station. However, glass bottles with caps attached provide the same opportunity for such a neck ring guide structure. As used in this disclosure and the appended claims the term neck ring guide is intended to cover such equivalent structure as will handle capped glass bottles. These neck ring guides define slots for slidably receiving the articles as best shown in Fig. 3. The upstream ends of these neck ring guides are provided well upstream of thedownstream edge 34a of the ramp, and thedownstream edges 42a of the neck ring guides are provided at a position approximately at the middle of the load station 40̸ (that is in the middle of the case C′ shown at the load station 40̸ in Fig. 1). - As mentioned previously the cases C, C are fed in the downstream direction initially by the
case conveyor 22 and then by the laterally spaced verticallyadjustable case conveyors case conveyors flight bars case conveyors - The articles are controlled in their movement so as to correlate with movement of the underlying case by rotating discs 60̸, 60̸ provided on a
common shaft 67 and driven by adrive motor 63 best shown in Fig. 2. Each disc 60̸ has at least one lug or protuberance provided adjacent its periphery as indicated generally at 62. Preferably, twosuch lugs protuberances - Fig. 4 shows the case C′ being loaded and being guided between the side guides as the case is controlled by the
forward flight bar 52. The underlying spaced apartcase conveyors flight bar 52 so that theflight bar 52 acts to hold back the case C and closely control its movement relative to the overhead series of discs 60̸. - Fig. 5 shows the
drive motor 63 for rotating the discs 60̸. The discs are provided in a subassembly which is readily removable for replacement by a subassembly (not shown) with discs of different diameter for handling articles of different size. Fig. 5 also shows that themotor 63 and its opposedbearing block 65 are vertically adjusted in thefixed frame 64. A pair ofparallel jack screws shaft 67.. - In summary the articles move downstream in side-by-side rows, being separated by lane dividers for movement on an inclined path defined in part by the
ramp 34 and in part by the neck ring guides 42. The cases C, C are moved toward the load station along a path below the articles and the position of each case is controlled by a flight bar conveyor 50̸ provided between the spaced apartconveyor belts - Article synchronizing means in the form of discs driven in timed relation to these flight bars 52, 52 are provided with at least one protuberance, and preferably two diametrically opposed lugs, for separating selective article rows. These discs 60̸ may have smaller lugs or protuberances between other article rows to assure that the operative lugs 62, 62 move into positions between the proper article rows to form groups or slugs of articles of the proper geometry for the case to be loaded.
- Each row of articles drops off the ends of the neck ring guides at approximately the midpoint of the case at the load station 40̸. At this point the articles are already down inside the case (see Fig. 1) and hence drop less than one-half the height of the case.
- Turning next to a discussion of Figs. 6-8A inclusively an apparatus of slightly different construction is illustrated for handling six pack shrink wrap container groups for loading in cases similar to those shown and described in their previous embodiment of Figs. 1-5. The individual articles or bottles may be small plastic injection molded soda bottles of the type shown in the foregoing description of Figs. 1-5, but these containers are grouped in individual six packs to form more conveniently handled six pack units or articles not only during the loading of the case in the machine to be described, but also for further handling by the retailer or customer.
- The apparatus of Figs. 6-8A includes the same fixed frame as described previously with legs 10̸ and 12, and with a vertically
adjustable beam 28 for supporting the head shafts of both thecase conveyor 22 and the spaced apart case conveyors 24. As in the previously described embodiment thisbeam 28 may be adjusted vertically for purposes of handling cases of different height and/or receiving articles of different height. - Comparing Figs. 6 and 7 it will be apparent that each article comprises a six pack carton which has been prepackage to provide a six pack configuration as described above. Two side-by-side lanes are provided for the articles A, A as these articles move down the
inclined ramp 34. Thedownstream end 34a may be provided just short of the entry to the load station 40̸ as in the previously described embodiment. However, neck ring guide need not be utilized because of the fact that the individual plastic containers or bottles have been partially preassembled to form the six pack carton shown. The six pack cartons provide sufficient stability for handling at the load station without necessity for supporting the usual bottles from neck ring guides. - As in the previously described embodiment the six pack carton units or articles are controlled in their movement so as to correlate with movement of the underlying case by rotating discs 160̸, 160̸. These discs are provided on a
common shaft 167 and driven by adrive motor 163 as best shown in Fig. 7. Each disc 160̸ has at least one lug or protuberance provided adjacent its periphery as indicated generally at 162, and preferably two such lugs are provided on each disc 160̸ as in the previously described embodiment. - The geometry of these is such that the radius of the disc corresponds roughly to the height of an article or six pack unit to be loaded, and so that the circumference of the disc is related to the length of the case to be loaded. As in the previously described embodiment, with two
protuberances - Comparing Fig. 6 and Fig. 6A the case being loaded will receive one article as shown in Fig. 6A followed by a second article as best shown in Fig. 6 as the case C′ proceeds through the load station with its motion uninterrupted except for the fact that the article synchronizing means in the form of the discs 160̸ will serve to match the speed of forward movement for these articles with the speed of forward movement of the cases, the latter being controlled by the flight bar conveyor 50̸. The flight bar conveyor on the embodiment illustrated in Fig. 6-8A is identical to that shown and described previously to the embodiment of Figs. 1-5. As in the previously described embodiment the support for the article indexing means in the form of disc subassembly is vertically adjustable in a fixed framework as described previously, and as shown at 64 in Fig. 7.
- Fig. 8 shows the
shaft 167 for rotatably supporting the disc 160̸, and it will be apparent that thisshaft 167 has couplings at each end so that the shaft can be easily removed for replacement by disc subassemblies of different geometry for accommodating articles of different geometry. - In summary, the articles A, A move downstream in side-by-side relationship being separated by fixed lane dividers so that the articles will move down the inclined path defined solely by the
ramp 34. The cases C, C are moved toward the load station 40̸ along a path below the articles and each case is indexed by a flight bar conveyor 50̸ provided between the spaced apartconveyor belts - Each row of articles drops off the
downstream end 34a of theramp 34 at approximately the midpoint of a load station 140̸ which load station 140̸ is defined slightly upstream of the load station 40̸ referred to in the previously described embodiment because of the absence of the neck ring guides. At this point, at the load station, the articles are loaded in orderly rows inside the case (see Figs. 6 and 6A). The articles comprising the six pack carton shown in Figs. 6 and 6A will generally drop a vertical distance equal approximately to the height of the case C to be loaded.
